I accept all and any input. I consider myself to be the manager of this FAQ for the good of everyone, not the absolute and controlling owner Of The FAQ. I do not always write in a completely coherent manner. What makes sense to me may not make sense to others.

If the community wants something added or deleted, I will do so. I removed any e-mail and last name references to someone making a suggestion or addition. This is so that someone doesn't get upset at this FAQ and do something stupid. If you don't mind having your e-mail in this FAQ (or where it is required), please tell me.

First off if you received a spam (Unsolicited Commercial E-Mail) there is no "easy" way to get the spam stopped. Generally if you reply (unsubscribe) all this does is confirm that your e-mail address is "live" and just gets your e-mail address sold to other spammers.

Spam has to be dealt with one at a time. Sorry, it isn't easy to stop the spam. The "Internet" (the collective non-profit and profit entities of the network) is trying to fix this problem but it is taking time.

Before trying to determine where the post or e-mail originated from, you should realize that (just like the The National Enquirer http://www.nationalenquirer.com/ or a logical argument from Canter and Siegel) the message will have *some* amount of truth, but all or most of the information may be forged. Be careful before accusing someone.

Commands used in this FAQ are UNIX & VMS commands. Sorry if they don't work for you, you might wish to try looking around at your commands to find an equivalent command (or I might be able to help out some).

There are programs for the Macintosh and Windows machines that do the same thing the UNIX commands do, see the above URL's for where to locate this software.

And no, I am not going to tell you how to post a fake message or fake email. It only took me about 2 days (a few hours a day) to figure it out. It isn't difficult. RTFM (or more appropriately, Read The @&%^@# RFC).

Every e-mail or post will have a point at which it was injected into the information stream. E-mail will have a real computer from which it was passed along. Likewise a post will have a news server that started passing the post. You need to get cooperation of the postmaster at the sites the message passed thru.

Then you can get information from the logs telling you what sites the message actually passed thru, and where the message "looked" like it passed thru (but actually didn't). Of course you do have to have the cooperation of all the postmasters in a string of sites. (Tracing an e-mail message)

 
 
Tracing an e-mail message

To trace the e-mail you have to look at the header.              Back to top of page
Most mail readers
do not show the header because it contains information that is for computer to computer routing. The information you usually see from the header is the subject, date and the "From" / "Return" address. About the only thing in an e-mail header that can't be faked is the "Received" portion referencing your computer (the last received).

You will need to take a look at the headers on the message as follows (Thanks to Michael, Piers and others) :

Claris E-Mailer - under Mail select Show Long Headers.

Eudora (before ver. 3) - Select Tools , Options... , then Fonts & Display then Show all headers

Eudora (ver. 3.x, 4.x IBM or Macintosh) - Press the BLAH button on the incoming mail message

For Mac Eudora 4.x, hitting the following will cause Eudora to alter its default setting so that BLAH will be automatically selected for all new email received after this switch is set:

x-eudora-setting:123=y When checked, Eudora will show all the headers from messages, not just an abbreviated set.

HotMail - To expose the full message header, click "Options" on the Hotmail Navigation Bar on the left side of the page. On the Options page, click "Preferences." Scroll down to "Message Headers" and select "Full."

For Lotus Notes 4.6.x - From the menu bar, select Actions, then Delivery Information. Copy the information from the bottom box into your e-mail report at the top of the spam.

For Lotus Notes R5 - From the menu bar, select Actions, then Tools, then Delivery Information. Copy the information from the bottom box into your e-mail report at the top of the spam.

MS Outlook - Double click on the email in your inbox. This will bring the message into a window. Click on View - Options. You can also open a message then choose File....Properties....Details.

MS Outlook Express - Alt-Enter, or Alt-F then R.

MS Outlook Express - More Detailed:

To look for, copy and send headers In Outlook Express

1- Press CTRL F3

2- Press CTRL A

3- Press CTRL C

4- Press Alt F4. (At this point the message is already copied)

5- Open a new message. Right click and paste or select Edit and paste.

Netscape 3 - In the mail viewing window: Options Show Headers All - When all the headers are displayed in the NS3 mail window, they are formatted. This is much more readable than the display in a text editor such as Notepad.

Netscape 4.xx - Double click on the email in your inbox. Click on View - Headers - All.

PINE - You have to turn on the header option in setup, then just hit "h" to get headers.

Yahoo - 1.Log into your Yahoo! Mail account.

2.Click the "Options" link on the left-hand navigation bar.

3.Click the "Mail Preferences" link on the right.

4.Locate the Show Headers heading and select "All."

5.Click the "Save" button to put your new settings into effect.

 

Another way to show you how to display headers, please see (with some good screen shots):

http://www.wurd.com/eng/ABCs/ms_headers.htm - MS Outlook Express and Internet Mail

http://www.wurd.com/eng/ABCs/mac_headers.htm - MS Outlook Express for the Mac

http://www.wurd.com/eng/ABCs/ns_headers.htm - Netscape Messenger or Netscape Mail

 

Programs that do not comply with any Internet standards (like cc-Mail, Beyond Mail, VAX VMS) throw away the headers. You will not be able to get headers from these e-mail messages.

Aussie tells us that in Pegasus to view the full headers for each message, use CTRL-H. This will show the full headers for the particular message, but will not add them to any reply or forward. You need to cut/paste the message into the reply/forward to send these headers.

Richard tells us with Nettamer, a MS DOS based email and USENET group reader you must save the message as an ASCII file, then the full header will be displayed when you open the saved file with your favorite ASCII editor.

At this point if you are "pushing the envelope" on your ability to figure out how to get that complaint to the correct person, I would suggest joining the Usenet group alt.spam or news.admin.net-abuse.email and post the message with a title like "Please help me decipher this header". Unfortunately there is no "single" place to complain to about spam (or Unsolicited Commercial E-Mail). Complaints have to be directed to the correct ISP (Internet Service Provider) that the spam originated from. See the below section entitled "Reporting spam".

 

URL's to help you figure out how to look at the headers:

http://www.concentric.net/~Nvam

http://www.rahul.net/falk/mailtrack.html

 

A little different description of headers:

http://ddi.digital.net/~gandalf/trachead.html - Line by line tracing of a spammers e-mail

http://help.mindspring.com/features/emailheaders/index.htm

http://www.stopspam.org/email/headers/headers.html - In depth header analysis

 

There is spamming software that sends the e-mail directly to your computer.
This makes only one received line in the e-mail making your life many times easier.
The computer that is not your computer is the spamming computer.

Also, please look through the body of the message for e-mail addresses to reply to. Complain to the postmasters of those sites also (see below for a list of complaint addresses).

Gregory tells us that assuming a reasonably standard and recent sendmail setup, a Received line that looks like :

Received: from host1 (host2 [ww.xx.yy.zz]) by host3

(8.7.5/8.7.3) with SMTP id MAA04298; Thu, 18 Jul 1996 12:18:06 -0600

Shows four pieces of useful information (reading from back to front, in order of decreasing reliability)

- The host that added the Received line host3

- The IP address of the incoming SMTP connection ww.xx.yy.zz

- The reverse-DNS lookup of that IP address host2

- The name the sender used in the SMTP HELO command when they connected host1


Looking at the below we see 6 received lines.
Received lines are like links in a chain. The message is passed from one computer to the next with no breaks in the chain. The received lines indicate that it ended up at ddi.digital.net (my computer) from mail.bestnetpc.com  It was received at mail.bestnetpc.com from unknown (HELO paul-s.-aiello) ([205.160.183.123]).

The last three lines suggests that it was received at

in2.|bm.net from mh.tomsurl|.com and from reb50.rs41|1date.net
Since none
of these computers are in the first two received lines then
we can ignore these lines and every received entry after this line (this UCE had 4 or 5 more faked Received lines in it that were deleted for this example). We also know that these lines are faked because no domain name has a "|" character in the name. Domain names only have alphabetic or numeric characters in the name.

Do not get confused by the "Received: from unknown" portion. The word "unknown" can be *anything* and should be ignored--because this is whatever the spammer put in the SMTP HELO command when they connected to the SMTP server.

Received: from mail.bestnetpc.com (IDENT:qmailr@mail.bestnetpc.com [205.160.183.3]) by ddi.digital.net (8.9.1a/8.9.1) with SMTP id CAA10768 for gandalf@digital.net; Thu, 26 Nov 1998 02:55:11 -0500 (EST)

Received: (qmail 25259 invoked from network); 26 Nov 1998 08:05:49 -0000

Received: from unknown (HELO paul-s.-aiello) ([205.160.183.123]) by mail.bestnetpc.com with SMTP; 26 Nov 1998 08:05:49 -0000

Received: (from uudp@lcl|lhost) by in2.|bm.net (8.6.9/8.6.9) id CFF569794 for suppressed; Thursday, November 26, 1998

Received: from tomsurl|.com (mh.tomsurl|.com [100.257.57.69]) by m4.tomsurl|.com (8.6.12/8.6.12) with ESMTP id PAA21932 Thursday, November 26, 1998

Received: from reb50.rs41|1date.net (root@reb50.rs41|1date.net [256.36.1.176]) by tomsurl|.com (8.6.12/8.6.12) with ESMTP id PBA023891 for suppressed;

 

So we complain to whomever owns unknown (HELO paul-s.-aiello) ([205.160.183.123])  Make sure that you do a nslookup (or use http://samspade.org/t/ , put the address in the section "address digger", click on Whois IP block and Traceroute and click on "do stuff") on the IP address's. I try to verify 205.160.183.123 is paul-s.-aiello

Indeed paul-s.-aiello does not even exist and 205.160.183.123 does not resolve to a name when I do a NSLookup. Next would be a traceroute. See further below for more in-depth tracking on resolving an IP.

IP portion = 205.160.183.123

Traceroute 205.160.183.123 gives us:

See the traceroute section below for how to interpret the "*" (and other codes) that are returned from a traceroute.

Note - if you see something like the following realize that the only portion you can trust is within the "([" and the "])". The spammer put in the (faked) portion "mail.zebra.net (209.12.13.2)" :

Received: from mail.zebra.net (209.12.13.2) ([209.12.69.42])

 

Kamiel tells us that you might also want to make sure that the IP is not hosted by an intermediary site. Check it out at: http://www.arin.net/

You should complain to the abuse@ or postmaster@Last Two or Three words at the end of the name. I would complain to abuse@iag.net OR abuse@espire.net (but NOT both sites) since after looking below at the list of complaint addresses in this FAQ there are no alternate addresses for iag.net or espire.net. Unless it is a "major provider" (someone in the below complaint list) I usually complain to the upstream provider rather than risk the chance of complaining to the spammer and being ignored. If you go too far up the chain, however, it may take quite some time for the complaint to filter down to the correct person.

Louise tells us that you are entitled to make an 'alleged' accusation but to prevent yourself from being libel, prefix your statement with:-

"Without prejudice: I suspect you are the culprit of such and such."

The constitutional and legal boundary of 'Without prejudice' exempts Politician's opinions being spoken publicly and this prefix is often adopted by Solicitors (English) or Lawyers/Attorneys (USA).

I use : abuse@XXXXX - Without prejudice I submit to you this Unsolicited Commercial E-Mail is from your user XXXX. UCE is unappreciated because it costs my provider (and ultimately myself) money to process just like an unsolicited FAX. Please look into this. Thank you.

 

BE SURE to verify the IP address.
Windows '95 machines place the name of the machine as the "name" and place the real IP address after the name, meaning a spammer can give a legitimate "name" of someone else to get someone innocent in trouble. A spammer at cyberpromo changed their SMTP HELO so that it claimed to be from Compuserve. The Received line looked like the below, but a quick verification of the IP address 208.9.65.20 showed it was indeed from cyberpromo :

Received: from dub-img-4.compuserve.com (cyberpromo.com [208.9.65.20]) by karpes.stu.rpi.edu

 

The below e-mail was passed to me thru a "mule" (un1.satlink.com [200.9.212.3]).
The Spammer hijacked an open SMTP port to reroute e-mail to me:

Received: from un1.satlink.com (un1.satlink.com [200.9.212.3]) by ddi.digital.net (8.9.1a/8.9.1) with ESMTP id GAA06372; Fri, 27 Nov 1998 06:53:20 -0500 (EST)

Received: from usa.net ([209.86.128.234]) by un1.satlink.com (Netscape Messaging Server 3.54) with SMTP id AAT2FEA; Fri, 27 Nov 1998 08:46:07 -0200

A NSLookup on 209.86.128.234 resolves to user38ld07a.dialup.mindspring.com, so after I complain to mindspring.com I also send the postmaster of the open SMTP port the following :

postmaster@XXXXX - Your SMTP mail server XXXXX was used as a mule to pass (and waste your system resources) this e-mail on to me. You can stop your SMTP port from allowing rerouting of e-mail back outside of your domain if you wish to. FYI only. Info on how to block your server, see:

http://maps.vix.com/tsi/

http://mail-abuse.org/rbl/usage.html

http://samspade.org/t/

http://www.abuse.net/relay.html - Test for server vulnerability

 

Now that Cable Modems are so popular, companies are starting to put their "personal" e-mail servers on cable / DSL modems and are (of course) not configuring them correctly. I received UCE from an open SMTP server:

Received: from SDMAIN (DT1-A-hfc-0251-d1132e93.rdc1.sdca.coxatwork.com [209.19.46.147]) by ddi.digital.net (8.9.3/05.21.76) with SMTP id SAA04761; Fri, 30 Mar 2001 18:35:24 -0500 (EST)

Received: from Received: (qmail 554 invoked from network); 25 Mar 2001 23:56:02 (ip207.miami41.fl.pub-ip.psi.net [38.37.111.207]) by SDMAIN; Fri, 30 Mar 2001 10:19:58 -0800

Complain to Cox ( abuse@home.com in this case) about their open SMTP server.

 

There are some systems that "claim" to "cloak" e-mail. It is not true.
If you receive one that looks like the following :

Received: from relay4.ispam.net (root@[207.124.161.39]) by ddi.digital.net (8.8.5/8.8.5) with ESMTP id KAA28969 for gandalf@digital.net; Thu, 26 Jun 1997 10:41:46 -0400 (EDT)

Received: from --- CLOAKED! ---

or

Received: from cerberus.njsmu.com ([204.142.120.2]) by ddi.digital.net (8.8.5/8.8.5) with ESMTP id HAA06250 for gandalf@digital.net; Mon, 25 Jan 1999 07:11:18 -0500 (EST)

From: hostme39@aol.com

Received: from The.sender.of.this.untracable.email.used.MAILGOD.by.IMI

It is still broken down as follows :-
The route the e-mail took originated from one of the systems above the line marked "cloaked" or the line "untraceable" (in fact this makes it even easier to trace). There is no magic to it. Complain to that provider. If you get no response from the site that spammed, you should ask your provider to no longer allow the above site [207.124.161.39] to connect to your system.

 

It has been kindly pointed out to me that there is a "feature" (read "bug") in the UNIX mail spool wherein the person e-mailing you a message can append a "message" (with the headers) to the end of their message. It makes the mail reader think you have 2 messages when the joker that sent the original message only sent one message (with a fake message appended). If the headers look *really* screwy, you might look at the message before the screwy message and consider if it may not be a "joke" message.

There are also IBM mainframes and misconfigured Sun Sendmail machines (SMI-8.6/SMI-SVR4) that do not include the machine that they received the SMTP traffic from. You have to route the message (with headers) back to the postmaster at that system and ask them to tell you what the IP of the machine is that hooked into their system for that message.

An example of a Microsoft Exchange server that the "HELO" transaction is taken as the "From" portion (and is completely false "faked") :

Received: from dpi.dpi-conseil.fr (dpi.dpi-conseil.fr [195.115.136.1]) by ddi.digital.net (8.9.3/8.9.3) with ESMTP id KAA06614 for gandalf@digital.net; Thu, 26 Aug 1999 10:51:31 -0400 (EDT)

Received: from FIREWALL ([192.168.0.254]) by dpi.dpi-conseil.fr with SMTP (Microsoft Exchange Internet Mail Service Version 5.5.2448.0) id QW11TJV1; Thu, 26 Aug 1999 16:44:38 +0200

 

It has also been pointed out that someone on your server can telnet back to the mail port and send you mail. This also makes the forgery virtually untraceable by you, but as always your admin should be able to catch the telnet back to the server. If they telnet to a foreign SMTP server and then use the "name" of a user on that system, it may appear to you that the message came from that user. Be very careful when making assumptions about where the e-mail came from.

Note for AOL users when looking at headers:
If you get double headers at the end of a message (like the below) the spammer has tacked on a extra set of headers to confuse the issue. Ignore everything except the last set of headers. These are the *real* headers.

What computer did this e-mail originate from?   Back to top of page

You cannot generally tell by a e-mail header which specific computer the e-mail came from. Just about every time you dial into your ISP (Internet Service Provider) you are assigned a different IP address. If someone sends you an e-mail and they log out, the next time they log in their IP address will most likely be different. If the computer has a permanently assigned IP address *and* you have the cooperation of whomever owns that block of IP addresses you *might* be able to get information on who might have sent the e-mail.

About the only way to tell *exactly* which e-mail account the e-mail was sent from is to get the ISP (Internet Service Provider) to tell you. Usually the ISP will require you to get the local police involved (a warrant of some type) to force the ISP to give you that information. Even given that you know the account the e-mail originated from, a forger can find out that person's account / password and log in as them, they can gain access to that computer while the person who owns that computer is away from the computer or they could install a back door program that allows them to control that person's computer remotely. If this were to happen then the forger could send the e-mail and the nobody would know who *specifically* sent the e-mail.

is a type of email distribution in which email is sent to a fixed site which holds a list of email recipients and mail is distributed to those recipients automatically (or through a moderator).

A LISTSERVER is a software program designed to manage one or more mailing lists. One of the more popular packages is named "LISTSERV". Besides Listserv, other popular packages include Listproc which is a Unix Listserv clone (Listservs originated on BITNET), Majordomo and Mailserve. Most importantly -- not all mailing lists run on listservers, there are many mailing lists that are manually managed.

You may hear of mailing lists being referred to as many things, some strange, some which on the surface make sense, like "email discussion groups". But this isn't accurate either, since not all mailing lists are set up for discussion.

Istvan suggests "Majordomo software is remarkably funny about headers. It does not like headers which contain anything odd. All messages the software receives which do not conform to its rigorous standards are simply forwarded to the list moderator. It turns out this feature is effective at stopping between 80 and 90% of spam actually getting to the list."

Kirk tells us that you can set majordomo up so that new subscribers have to reply to a subscribe request, thus verifying the address is legit. Additionally the lists can be configured so that only subscribers can post. And finally you can put filters on content. I've got the list I manage configured to reject multipart email and email which contains html.

Jeff adds that this would be the closed+confirm option in the configuration file so that only subscribers can post. Also, to prevent multipart or HTML this would be the taboo_headers configuration.

Richard mentions "Listserv can be configured to restrict non-members from sending to a list and can restrict spam based on the headers similar to Majordomo. I've used both of these features successfully. You can read more about Listserv capabilities, if you are interested, at:

http://www.lsoft.com/listserv.stm

http://www.lsoft.com/spamorama.html#FILTER (info on its spam filter)

I suspect that Listserv's spam filter may be better than Majordomo's (but I've not managed any Majordomo lists)."

Jeff adds that having ran a majordomo list for almost 4 years, I find majordomo to be every bit as good. I should, however, qualify that; the listowner needs to have his/her clueons in good working order. Simply put, no listowner in their right mind should leave their majordomo lists set to anything other than closed+confirm. Alas, there are listowners who will leave their lists wide open. I've also seen others knock themselves dead creating their own filters just so a listmember can post to the list from a web-based e-mail account while on vacation. I usually tell anyone in such a situation to subscribe to the list from whatever free e-mail account they plan to use. IMO, I cannot justify compromising list security for such reasons. Lists should be closed+confirm...plain and simple.

 

Example Header appears below:

This is a post from Kevin Lipsitz for his "=== FREE 1 yr. USA Magazine Subscriptions". The latest information indicates that the state of New York has told him he should stop abusing the Internet for a while ... lets hope it is forever. In relation to the Internet he makes a slimy used car salesman look like a saint.

For more info about "Krazy Kevin" or the Magazine Spam , Tony tells us the page "Stop Spam!" is available in html format at:
http://www.iac.co.jp/~issho/stop-spam.html

But as David reminds us, There are a million Kevin J. Lipsitz's out there. All selling magazines, Amway, vitamins, phone service, etc. All the losers who want to get rich quick, but can't start their own business.

Like : http://com.primenet.com/spamking/

 

That having been said, e-mail from a Listserve can usually be broken down the same way as "normal" e-mail headers. There are just more waypoints along the way. As you can see from the above, the e-mail originated from : emout09.mail.aol.com

Jeff also mentions that news.admin.net.abuse.e-mail is a good newsgroup to monitor about how to keep spam off the listserve. I have seen mailing list issues arise occasionally.

 

 


Reporting Spam and tracing a posted message Back to top of page

If someone posts a message with your e-mail in the From: or Reply-To: field, it can (and will if you request) be canceled. Please repost the message to news.admin.net-abuse.misc WITH THE HEADERS (or it will probably be ignored) so that the message cam be canceled (the message-id is the most important) with a suggested subject of the following:

Subject: FORGERY Subject from the Spam message

Or you can look at the Cancel FAQ at :

http://www.ews.uiuc.edu/~tskirvin/faqs/cancel.html

 

Try to make sure that the message has not already been posted to news.admin.net-abuse.misc, news.admin.net-abuse.email or news.admin.net-abuse.usenet and that it is less than 4 or 5 days old. Chris reminds us that yes, there are a lot of annoying, off-topic and stupid postings out there. But that doesn't make it spam. _Really_. All we're concerned with is _volume_. Don't report any potential spams unless you see at least two copies in at least 4 groups. The content is irrelevant. Spam canceling cannot be by content.

For off topic posts, see http://ddi.digital.net/~gandalf/trollfaq.html

 

The first thing to do is to post the ENTIRE message (PLEASE put the header in or it will probably be ignored) to the newsgroup news.admin.net-abuse.misc. Do not reply or post it back to the original group. A suggested subject is one of the following:

Subject: EMP Subject from the Spam message

Subject: ECP Subject from the Spam message

Subject: UCE Subject from the Spam message

Subject: SEX Subject from the Spam message

Please include the original Subject: from the original Spam so that it can easily be spotted. Thank you.

 

Take a careful look at the header, if there are "curious characters" (characters that look like garbage) in the X-Mailer: line, or any other line in the header, then delete those characters otherwise the message may end up truncated. The offending line consists of the EIGHT characters D0 CF 11 E0 A1 B1 1A E1 (in hex).

If the post is particularly amusing (Spammer threat or a postmaster threat), put C&C in the subject. Seymour tells us it means Coffee and cats. This originated from a post claiming that a particular outrageous article had caused spewing of coffee into the keyboard and jumping while holding a cat, resulting in scratched thighs.

An Excessive Multiple Post (EMP) may exceed the spam threshold and may be canceled. An Excessive Cross Post (ECP) may not be canceled because it hasn't reached the threshold. A UCE is for Unsolicited Commercial Email, SEX is for off-topic sex-ad postings.

Make Money Fast message is immediately cancelable and are usually canceled already by others, so please do not report MMF posts. See MMF section below.

Tracing a fake post is probably easier than a fake e-mail because of some posting peculiarities. You just have to save and look at a few "normal" posts to try to spot peculiarities. Most people are not energetic to go to the lengths of the below, but you never know.

Dan reminds us that first you should gather the same post from *several* different sites (get your friends to mail the posts to you) and look at the "Path" line. Somewhere it should "branch". If there is a portion that is common to all posts, then the "actual" posting computer is (most likely) in that portion of the path. That should be the starting postmaster to contact. Be sure to do this expeditiously because the log files that help to trace these posts may be deleted daily.

 

If you *really* want to see some fake posts, look in alt.test or in the alt.binaries.warez.* groups.

A fake post:

This poor lady (Name deleted by suggestion) was abused by someone for a couple of days in an epic spam. Many messages were gathered. The message ID was different for several messages. But several anomalies showed an inept poster.

The headers were screwed up, and when looking at a selection of messages from several sites, the central site was news.net99.net, where goodnet.com gets / injects news at. This lead to the conclusion that either goodnet.com or news.net99.net should be contacted to see who the original spammer was. I never heard the results of this, but the spamming eventually stopped.

 

You can try looking at sites & see if they have that message by :

telnet s46.phxslip4.indirect.com 119

Connected to s46.phxslip4.indirect.com.

200 s46.phxslip4.indirect.com InterNetNews server INN 1.4 22-Dec-93 ready

head DHLMvE.24H@goodnet.com

430

Message was not found at that site, so it did not go thru that computer, or the article has already expired or been deleted off of that news reader.

Converting that IP to a name   Back to top of page

When all you have is a number the looks like 204.183.126.181
and no computer name, then you have to figure out what the name of that computer is. Most likely if you complain to  postmaster@[204.183.126.181]  it will go directly to the spammer themselves (if it goes anywhere at all).

Whois or a traceroute will give you the upstream provider, complain to that organization.

Marty reminds us that there are some "special" IP's that are allocated as private networks. These fall within the confines of 0.0.0.0 to 255.255.255.255 but should be ignored. If the number is greater than 255 then it is faked. The addresses are :

Class Start Address End Address

A 10.0.0.0 10.255.255.255

127.0.0.0 127.255.255.255 - Loopback addresses

B 172.16.0.0 172.31.255.255

C 192.168.0.0 192.168.255.255

D 224.0.0.0 239.255.255.255 - Multicast

E 240.0.0.0 255.255.255.255 - Multicast

See : http://www.umnet.umich.edu/groups/UMnet-Routing/UAssignedPrivateIP.html

First off try using NSLookup (there is software for PC's, I use http://samspade.org/t/ , put the address in the section "address digger", click on Whois IP block and Traceroute and click on "do stuff" or look at the URL's at the bottom of this FAQ). If the NSLookup does not give you a name then try a Traceroute. Somewhere you will get a "name" and at that point I would complain to the postmaster@that name. See below for complaint addresses.

See (as of 1997):

http://ipindex.dragonstar.net/a/indexa.html - Who owns which Class A addresses

What to do with "strange" looking Web links Back to top of page

http://1085381292/ has some %-encoded characters, but decoding those gives http://1085381292/

1085381292 is just another way of writing the IP address 64.177.154.172

To convert a decimal number to a "dotted quad octet" : http://3438189385/yt/rotten1/

You can put this "strange" number in at any of the following :
http://samspade.org/t/

http://www.webspawner.com/users/ipconverter

http://www.isit.nl/cgi-bin/isitbv/ip.cgi

You can also download Cyberkit v. 2.5 to do the translation.

http://www.netdemon.net/ - Automatic url decoder built in for Windows 95.

As well as the Windows 95 based URL decoding tool, it has been ported and made available to everyone as a CGI: http://www.netdemon.net/decode.html

This CGI handles ALL the recent types of spammer tricks, including decimal, octal, hex addresses, username/password tricks, hex encoded characters, and redirectors.

And you get an answer like:

204.238.155.73

You can try the "strange" number at : http://www.abuse.net/cgi-bin/unpackit

 

Kirk tells us wsftp and the traceroute that comes with wsftp will take those number and automatically translate them into the IP addresses.

Or under Widows 95 :

start -- Programs -- Accessories -- Calculator

Choose view -- Scientific

Put in the "strange" number (3438189385) and click on HEX. You get: CCEE9B49

Then type in each of the two characters in HEX and click DEC after each number:

CC = 204

EE = 238

9B = 155

49 = 73

Viola ... Your IP is 204.238.155.73

 

For more general funny URLs, like http://23123443~32:3758493879/www.samspade.org/10.00.0.1/xxxstuff.html, try http://samspade.org/t/url.cgi?x

If you get a strange URL like: http://www.nt.dahouc.mx^t^b^t^e^t.com|net.fr^b^e^t^b^t^e^t^t.oooooooooooooooooo.com/nt/dahouchy/

Where the ^B = Control "B", ^T = Control "T", etc. you can look at the very end right before the first "/" to figure out what the site is, on this case it is oooooooooooooooooo.com, using port 80. The rest of it is "decoded" by oooooooooooooooooo.com to give the "real" site name.

For MS Windows the program at http://www.netdemon.net/ will decode these with ease.

 

If you are looking thru the HTML source and you get something like:

!-- CHANGE EMAIL ADDRESS IN ACTION OF FORM --FORM name="form" method="post" action="mailto:mortmail6@yahoo.com?subject=Debt1" enctype="text/plain"

Then take the "funny" looking part and paste it into the "Obfuscated URLs" section of http://samspade.org/t/ like so:

http://mailto:mortmail6@yahoo.com/?subject=Debt1

And you get:

mailto:href=">href="http://mailto:mortmail6@yahoo.com?subject=Debt1">http://mailto:mortmail6@yahoo.com?subject=Debt1

So then you send a complaint to yahoo.com asking them to delete their user mortmail6@yahoo.com.

 

If the site is a IP address like 198.41.0.5 you can do a DNS lookup to backtrack the site. A DNS lookup or a host command (see example below) uses the info in a Domain Name Server database. This is the same info that is used for packet routing. The UNIX command is :

nslookup 198.41.0.5

Commands:

nslookup hostname dns_server

or

dig @dns_server hostname

And you get :

Name: whois.arin.net

Addresses: 198.41.0.5, 198.41.0.6

If you are having problems with this, Josh suggests you try :

$ nslookup

Default Server: ddi.digital.net

 

Address: 198.69.104.2

set type=ptr

181.126.183.204.in-addr.arpa

Server: ddi.digital.net

Address: 198.69.104.2

Non-authoritative answer:

181.126.183.204.in-addr.arpa name = kjl.com

Authoritative answers can be found from:

126.183.204.IN-ADDR.ARPA nameserver = escape.com

126.183.204.IN-ADDR.ARPA nameserver = ns.uu.net

escape.com Internet address = 198.6.71.10

ns.uu.net Internet address = 137.39.1.3

 

Looking up IP address ownership   Back to top of page

InterNIC is your friend. The InterNIC Registration Services Host contains ONLY Internet Information (Networks, ASN's, Domains, and POC's). Please use the whois server at nic.ddn.mil for MILNET Information. Try :

Bruce tells us that there are three places where you can lookup an IP address, being the current trinity of Regional Internet Registries. These RIRs are:

Jeef says Geektools will work out which one, as well as display the results.

Asia and Pacific Rim: APNIC - Asia Pacific Network Information Centre

whois.apnic.net http://www.apnic.net/apnic-bin/whois.pl

 

Americas and parts of Africa: ARIN - American Registry for Internet Numbers

whois.arin.net http://www.arin.net/cgi-bin/whois.pl

 

Europe and Surrounding Areas: RIPE NCC - RŽseaux IP EuropŽens, Network Coordination Centre

whois.ripe.net http://www.ripe.net/db/whois.html

 

Under Unix, you can use:

whois -h whois.arin.net 198.41.0.5

or

whois -h whois.apnic.net 198.41.0.5

or

whois -h whois.ripe.net 198.41.0.5

 

Each of the above three RIRs may refer to one of the other RIRs. Please do not send complaints to any of the RIRs as they merely provide contact information, and are not related in any way to the possible spammers.

Dan has said that the NIC technical contact is the address to contact if there is a technical problem with the name service records for that domain. Sending spam notifications to the zone tech contact is an abuse of the NIC whois records. Sending to the admin contact is marginally more justifiable, but should only be used after postmaster and abuse address has been tried. Sending a complaint to all of the intermediate sites in a traceroute should *not* be done, these sites in all likelyhood cannot do anything about the problem (with the exception of possibly the next to last site).

For domains that have invalid contact information you should contact the appropriate RIR (see above)

To see who the upstream provider is, try :

traceroute ip30.abq-dialin.hollyberry.com

You might get :

traceroute to IP30.ABQ-DIALIN.HOLLYBERRY.COM (165.247.201.30), 30 hops max, 38 byte packets

10 * * *

The first column is the "hop" that traceroute is working on. The next is the "computer" (and IP) of the computer at that hop. The last three numbers are the milliseconds it took to get an answer from that computer.

You can get "codes" instead of the milliseconds. An example of a "code" is the "* * *" for hop 10.

Here is a list of the codes:

? Unknown packet type.

H Host unreachable.

N Network unreachable.

P Protocol unreachable.

Q Source quench.

U Port unreachable.

 

* The Traceroute Packet timed out (did not return to you).   Back to top of page

Chris clarifies that a '*' in actuality could be caused by a timeout OR something listening on the UDP ports traceroute uses to get it's port unreachables back from, to work, OR the router simply does not support ICMP/UDP unreachable ports and traceroute cannot determine it's status so it displays asterisks.

Humm..... Seems that after abq-phx-gw1.indirect.com we get no response, so *that* is who I would complain to... or you can just send a message to postmaster@indirect.com ... If that doesn't work then complain to MCI.net.

JamBreaker sez : Be sure to let the traceroute go until the traceroute stops after 30 hops or so. A reply of "* * *" doesn't mean that you've got the right destination; it just means that either the gateways don't send ICMP "time exceeded" messages or that they send them with a ttl (time-to-live) too small to reach you.

Try 'dig' (or one of its derivatives), it is used to search DNS records :

Getting a World Wide Web page busted   Back to top of page

Many spammers use throw away accounts, accounts that they know will be deleted as soon as the service gets a complaint. Of course the spammers mentality is "if it is free it is for me to abuse". If the spammer really annoyed you then you might wish to dig and get every account possible deleted.

What you need to do is actually go to the WWW page that they advertise, look at the page and usually the page will redirect you to another site (or possibly redirect 2 or 3 times). Send a complaint to these sites (with the original spam). It is important to explain to the site you are complaining to how you got to their site so that they don't ignore you.

In Netscape and Explorer there is an option to "view source". This will pop up a page with all of the http source from the page. This page will have all of the "links" to the next site.

If you look at the http source and it is unreadable (and sez "Haywyre"), take a look at :
http://www.netdemon.net/haywyre/  A list of Usenet complaint addresses

 

O.K... So you have a common site that you can complain to.
Good. If you cannot figure out where the message came from, you can post the FULL HEADERS (this is *very* important for tracing) to alt.spam, news.admin.net-abuse.misc, news.admin.net-abuse.email or news.admin.net-abuse.usenet (see the section entitled Reporting Spam and tracing a posted message). Usually you can get someone to help with the message.

If you complain (or asked to be removed) to the spammer directly, you may just be confirming a "real" live e-mail address, which may lead to even more junk e-mail. I would suggest complaining to the owner of the site only. You can send e-mail to foo.bar.com@abuse.net (where foo.bar.com is the provider you are complaining to) and it will get forwarded to the "best" e-mail address.. See http://www.abuse.net/

There is a list of admins to contact (besides the list contained here):  http://www-fofa.concordia.ca/spam/complaints.shtml

 

Greg reminds us that if you are complaining to a postmaster about a week-old post, don't bother. It's not on their server, they can't verify it. Make sure you use terms correctly. A recent trend is to call any off-topic post "spam". It's not. I deal with spammers and off-topic or advertising posters differently.

Other providers do also. Also, try to keep the clutter in your complaints down. I don't need a copy of the referenced RFC or statute. It doesn't help either of us if I can't find your complaint in between all the mumbo jumbo.
