relaying spam using mailing lists

by Gadi Evron

A friend of mine just wrote about what happened to an ezmlm mailing list he runs, and how it was recently used to relay spam (quoted below). All mailing list managers return bounces of some sort, for subscriptions, unsubscriptions, moderation, etc. (*configuration dependent*), some just quote the subject line though, as an example. Do we risk blocking by black lists for allowing mailing list bounces? Do we in blacklists block spam in bounces? We all see spam bouncing off our lists, how do we distinguish what's what? Especially if these are bounces themselves? How would mailman be vulnerable, if at all? Thanks go to Ellen from spamcop for the help. ----- People tend to think of SPAMers are a bunch of monkeys, i.e. know nothing, utilize off the shelf tools, and completely un-imaginative. I tend to differ, especially after what I saw happen… It began about 3 months ago, our ezmlm mailing list was starting to get a lot of bounces, and when I say a lot, I mean a lot. The number quickly risen to more than 100 per hour, all of them bounces caused by malformed ezmlm requests. These bounces weren’t ordinary, their body was composed of a SPAMed email. You would ask your self, why would someone use ezmlm to bounce emails? well you take our security oriented mailing-list, which has its credibility (both the IP address of the mail server’s credibility and the email address’s credibility) and you utilize it for your spamming needs. In addition, ezmlm will bounce almost any email it receives without thinking, and not only bounce it, but also include the entire incoming email, in our case the SPAM content. Making it a nice to use SPAM relay. After several weeks, our mail server was starting to get blocked by SpamCop, and others which regard bouncing email SPAM as regular SPAM. Several days ago, we decided to put an end to this shenanigan, we patched - yes changed the source code, as ezmlm doesn’t support the suppression of bouncing emails - ezmlm to stop it from sending back emails whenever something bad has happened, and low and behold a few hours after the change was put into place, our ezmlm was no longer being used to relay SPAM. The only option I can conclude from this is that the SPAMers use some-kind of technique (maybe even “SPAM” themselves) to detect whether it is still useful to use your SPAM relay for their needs, in this case our ezmlm configuration, and when it is no longer useful, they “conserve” their bandwidth and move on to their next target. ----- http://blogs.securiteam.com/index.php/archives/353 Gadi.

If ezmlm has a similar format, then it's easily done. There are some posts in the Archives about this, so you might want to look there for further information.

Re: [Mailman-Users] Large lists and Postfix

by bruce＠hams.com

From: Dan Delaney <Dionysos(a)Dionysia.org> > Thanks. So, considering the claims made about ezmlm for qmail, does > that have anything to do with ezmlm, or is it qmail that's making > mlm so fast? Ezmlm is a very lightweight mailing list manager, and it adds essentially no overhead to that of qmail. Mailman would add some more overhead, but still not enough to be significant. However, the main overhead of mailing lists is their overhead on _your_time_ to manage them, not the computer. Mailman is very good about reducing _that_ overhead, much better than ezmlm. Ezmlm's main advantage is that it uses the qmail "percent hack" to get reliable information about bounces - the "envelope from" address is different for each recepient, and you can tell who a bouncing message was addressed to by the address the bounce comes to. For example, mail to me would have an envelope From something like this: balloons-owner-bruce%hams.com(a)lists.hams.com If my address bounces, the bounce mail goes to that address, a qmail default rule catches it, and ezmlm decodes bruce%hams.com and realizes that I've had a bounce. It doesn't have to look at the bounce message at all, just the address it goes to. When I get sick of watching undecoded bounces go by, I'll add that "percent hack" feature to Mailman. Thanks Bruce

Email command in Mailman to get by e-mail a message (like ezmlm has)

by Ricardo Dias Marques

Hello, I think this is my post to the Mailman Users mailing list. Hi everyone! :) I supposed this would be a FAQ, but I can't find it in Mailman's web site. My question is: "Is there any email command (or other way) that allows you to be e-mailed a past message (or messages) that was sent to a Mailman managed mailing list?" Browsing the Mailman list archives, I could only find a reference from September 2002 (almost 7 years ago!) from a user (Fernan Aguero) asking the same thing, but not getting a reply: [Mailman-Users] add to whishlist? http://mail.python.org/pipermail/mailman-users/2002-September/022243.html I know that ezmlm has a "-get" command for doing this: EZMAN-0.32: ezmlm Commands http://www.ezmlm.org/ezman/ezman5.html >From that page: ---------------------------------------- -get Get a message or range of messages from the archive. Without argument it returns the messages since the latest digest. To retrieve a range of messages, use list-get.123_234@host(*). At most 100 messages are returned. Without ezmlm-idx, individual messages can still be retrieved by sending mail to list-get.123@host. ---------------------------------------- By reading the list of Mailman commands available in the following web page, it seems that Mailman (still) hasn't a command for doing that: Can I use email commands to interact with the Mailman server? http://www.washington.edu/computing/mailman/faqs/mailman.email.html Am I right? Is there some reason for not including this "get" message functionality in Mailman? Thanks in advance! :) Cheers, Ricardo Dias Marques lists AT ricmarques DOT net

Combining mailman and ezmlm

by Irwan Hadi

I use qmail as the MTA, and I've already installed ezmlm to serve domain list.somesite.or.id My question is, can I use mailman too, to serve the mailling list at list.somesite.or.id Because it seems mailman can give easier solution for person who just for the first time follow a mailling list. EZMLM has installed at /list and I have updated the /var/qmail/users/assign to deliver all mail addressed to list.somesite.or.id to /list BTW I read that mailman has smart detection of bounce mail o Smart bounce detection and correction o Integrated fast bulk mailing o Smart spam protection My question is, how this work, since the return-path of, for example this mailling list is Return-Path: <mailman-users-admin(a)python.org> so if mail to subscribers were bounce, then the admin will get the bounce ? ------- AFLHI 058009990407128029/089802---(102598//991024)

Re: [Mailman-Users] Auto-Responses

The auto-replies used to go to the > person that posted the message, not to the list. Actually both are wrong, auto-replies are supposed to go to the envelope sender, which is the list admin address. Ezmlm is much smarter than mailman for bounce processing since it uses VERP and knows exactly which user bounced. That said, unless you have a list that does reply to munging (forcing the reply-to to the list), auto responses should never ever reach the list, whether you're using ezmlm or mailman If an auto-responder is broken to the point that it answers receipients in the To/Cc fields, you can block the sender, but neither mailman or ezmlm can do anything about it. If you are using reply-to munging, that may be another reason to consider not doing it (but the sending mail server is still at fault) Marc -- Microsoft is to operating systems & security .... .... what McDonalds is to gourmet cooking Home page: http://marc.merlins.org/ | Finger marc_f(a)merlins.org for PGP key

Moving to mailman from ezmlm

by Daniel S. Reichenbach

Hi, we are currently testing Mailman on our development systems and really like it. Great work! Right now we use Qmail with the combination of vpopmail / ezmlm to run our mailing lists. We manage a lot of lists for Open Source projects and as of this mail we are near to 1GB of archived mails. Is there any kind of script to migrate vom ezmlm to mailman? Especially converting the archives to mailman would be a great thing. Greetings, Daniel -- Best Off GbR info(a)best-off.org One company.

ezmlm to mailman

by Daniel S. Reichenbach

Hi, I have searched a while through the list archives and google but found no reasonable way to convert an existing ezmlm list with subscribers and archive to a mailman list. Did anyone succeed in doing this? There seem to be a lot of posts in the archive, but none that reports success on this issue. The list is currently served by ezmlm and qmail, but the new servers have Postfix and Mailman available and no support for qmail. Any hints would be very appreciated. Thanks, Daniel S.

You should just need to convert the exmlm archive to mbox, then import it into mailman using the procedure here: http://www.python.org/cgi-bin/faqw-mm.py?req=show&file=faq05.001.htp A quick search for tools to convert ezmlm to mbox yielded a few results.
