Add "sender's name/email" to BODY of mail as header?

by Mal

I want all mails sent to the list to come from the list's email address... But, in this case, if the user forgets to sign their name at the bottom of their mail body, effectively the mail to the list is anonymous...! Is there a way to add the user name (or email address) to the top of each mail so that the mails have the name of the sender, while the mail itself comes from the list address? I have looked high and low for an answer, but noone seems to have the solution. Thank you! Mal

Setting MIME as default for new Non-Digest subscribers

by Steve Reiter

Hi - I have searched FAQ and archives to find an answer. Hoping you can help. I have a new list (with previously imported addresses) for announcements only, and wish these announcements to be received immediately. I set the defaults to allow non-digest and to not allow digest. I wish to send out announcements in html, and so wish to make the default for new subscribers be MIME. While I see a setting under Digest Options (MIME_is_Default_Digest), I don't see any equivalent option under Non-Digest Options... and new subscribers continue to come in as plain text. QUESTIONS: In order to avoid having to manually change this option for each existing subscriber, is there a way to force all existing subscribers to receive MIME in Non-Digest mode? If not, is there a way to force all NEW subscribers to be enrolled with MIME as their default? Also, is there a way to "lock" the MIME switch on, so that users who try to change their option to plain text will be prevented from doing so? Thanks - Steve

Mailman/Qmail/Plesk Problem

by Douglas G. Phillips

OK, I've got another problem with Qmail/Plesk/Mailman (same customer, rebuilt server). Plesk is 7.5.4 reloaded. Mail delivered fails with "need GID 110 got 101" error. I set up the brute-force wrapper to deliver with GID 110, and set the permissions correctly for it to work. Now, I'm getting the following (broken up into multiple lines for courtesy): qmail: 1157518628.995172 delivery 726: success: group_mismatch_error._Mailman_expected_the_mail_wrapper_script_to_be/ executed_as_one_of_the_following_groups:/[mail,_nobody,_mailman],/ but_the_system's_mail_server_executed_the_mail_script_as_group:_"popuser"./ Try_tweaking_the_mail_server_to_run_the_script_as_one_of_these_groups:/ [mail,_nobody,_mailman],/or_re-run_configure_providing_the_ command_line_option:/'--with-mail-gid=popuser'./Failed_to_start_ /usr/lib/mailman/mail/mailman./did_0+0+1/ I'm about ready to pull my hair out. I even added the popuser user to the mailman group in /etc/passwd. So, that being said, are there any ideas out there? I have been messing with this for a week, and have not come up with anything else to do. -- Douglas G.

migrating Mailman server

by Peter Matulis

I have the task of setting up a replacement for an existing Mailman/Postfix server. I am new to Mailman and I am looking for some guidance in this transition. Mailman is currently being used solely as a diffusion of information. That is, it does not accept contributions from list members (read-only). Firstly, should I attempt to migrate data/files over to the new system or should I start fresh? The new system will be running OpenBSD 4.0. Other comments welcome. Peter

rare problem

by Jesús Oliván

Hi! i'm using mailman 2.1.5 on a Solaris box, and i've got a very rare issue... if i try to post a list using a non-suscribed email address, and this email address is included in non-suscribers allowed senders, it accepts my post... but if i use a regular expression like this ^[A-Za-z0-9.\-_%]+(a)[A-Za-z0-9.-]*mynet.com$ and try to post using a from line using more than 30 characters (from line splits in two in mail header then) and an accent. Then, mailman doesn't accept this mail and return it to me, although this email address is under my.net.com domain. Anyone can help, plz? =)

no archives, no logs after system failure

by douglas repetto

Hello, Our server recently had hard drive problems, and the system was copied to another drive where it seems to be more or less happy. But we're having a strange Mailman problem (Mailman 2.1.5 on OSX Server 10.4.10): the lists are running, mail is being delivered, but no archiving is taking place and nothing is being written to the log files. The last change date for all log files is the day the original drive died, as is the date of the last archived messages to our lists. Otherwise all seems to be well... Can someone help me with some ideas of where to start looking? I've run out of ideas at this point. Permissions seem to be fine. Nothing is in our system logs indicating a problem. I run: roar:/var/mailman/logs root# /usr/share/mailman/bin/mailmanctl stop Shutting down Mailman's master qrunner roar:/var/mailman root# /usr/share/mailman/bin/mailmanctl start Starting Mailman's master qrunner. With no problems, but as mentioned, the stop/start does not appear in the logs. Any ideas? thanks, douglas -- ............................................... http://artbots.org .....douglas.....irving........................ http://dorkbot.org .......................... http://music.columbia.edu/cmc/music-dsp .......... repetto....... http://works.music.columbia.edu/organism ............................... http://music.columbia.edu/~douglas

Making list owner (listname-owner) appear in Return Path

by D G Teed

We are doing well in our migration from MJ2 to mailman. The default of sending emails with the -bounce address doesn't fit with our needs. We'd like it to work the way it did with MJ2, where the listname-owner type of address was in the Return-Path. Typically we set our list owner to be some administrative email address which several of us can check for interesting items or bulk delete after some time. In other cases, the owner of some fund raising campaign wants to receive bounce notifications to see immediately what addresses are not current. I think my answer is to edit SMTPDirect.py to set the Sender and Return Path, but I'm not sure what variable I need to use there. Is 'mlist.owner[:]' what I'll need? I'd want the specific list owner, not the site mailman owner. None of these are publicly subscribe-able lists, so the features of bounce processing are not valuable to us. Any suggestions? --Donald

specific (1) LHS and (2) sender rules to frustrate spam/phishing

by Rich Kulawiec

Two related suggestions. (1) LHS (left-hand-side) rules Any incoming mail message whose putative sender matches: do-not-reply@ do.not.reply@ donotreply@ no-reply@ no.reply@ noreply@ and which is directed to any of the Mailman standard aliases can be rejected (not bounced [1]) with SMTP status 550 (extended status 5.7.1) since either: (a) it's a forgery, therefore there's no point in letting Mailman attempt to emit a reply -- or even in accepting the message to begin with. (a) it's not a forgery, therefore there's no point in trying to reply to it. (Nor is there any point in permitting it to subscribe to a list or send any traffic to one.) Arguably, this could be done in some MTAs by configuring rejection of those LHS patterns on a per-local-user basis; but I'll argue that doing this in Mailman itself would be more useful, since many (perhaps most) sites don't use per-local-user configuration (and perhaps don't know how). Moreover, any site running multiple mailing lists would need to set this up for every Mailman alias for every mailing list -- so it seems simpler to handle it inside Mailman itself. My guess is that this should be a switchable feature, named something like "reject-noreplies". (Not that I can envision a need to switch it off, but I think it'd be more conversative to have that option.) (2) sender rules Any incoming mail message whose putative sender matches the list below can also be rejected (SMTP status 550, extended status 5.7.1) because these addresses will never send traffic to any mailing list nor subscribe to any mailing list. There's thus no point in expending the bandwidth/CPU necessary to process them, nor in forwarding them on to list admins for possible approval -- any message from these addresses to any Mailman-related address is invariably a phish attempt. I'm sure this list is incomplete; I built it by looking at incoming attempts received locally in 2007. It's not meant to be complete, only illustrative. Again, this could be done at the MTA level by blocking on a per-local-user basis, but (as above) I think wiring it into Mailman would make it useful to people who do not have their MTAs so configured. And this should probably also be switchable feature, perhaps named "reject-obvious-phishes".

cases, the check can be carried out by doing some simple string-matching. The second list will need ongoing (and careful) maintenance -- and one way to achieve that might be to enlist the cooperation of the domains in question. However, note that (a) under-inclusion is no worse than the current situation and (b) over-inclusion is unlikely given even a modicum of scrutiny applied to prospective list entries. ---Rsk [1] The difference between a reject and a bounce: a reject is performed by emitting the appropriate SMTP status code and closing the connection; that is, the message is refused while the SMTP connection is open from the sending side. A bounce is performed by accepting the message (again, emitting the appropriate SMTP status code), then performing further processing, deciding not to accept the message, and attemping to "return" the message to the putative sender. The simplest way of putting this is "reject good, bounce bad", since bounces invariably result in outscatter (aka "backscatter"), which is a form of spam, which in turn will cause sufficiently egregious emitters to be (correctly) blacklisted. Note as well that various mitigating strategies designed to blunt the effects of bounce-instead-of-reject policies lose entirely due to rampant forgery, DNS redirection, an estimated 100M+ fully-compromised systems, and widespread failure of end-user ISPs to control outbound SMTP abuse. So saying that it's immensely preferable to reject rather than bounce is an understatement.
