Check the archives of the list. I run Mailman 2.1.13 (soon to be 14) on Ubuntu Dapper (to be converted to the latest LTS release). I built my own Mailman package from the SourceForge source because most of the Debian/Ubuntu patches were undocumented as to what they did, and one removed a necessary library.

Mailman Crashes Regularly
by Aaron Kreider Nov. 11, 2010

Nov. 11, 2010

I'm getting regular mailman crashes every 2-4 weeks. I've had 4 so far. I'm running a centos VPS with mailman 2.1.13. What is the best way to restart mailman? I've been restarting the entire vps, which obviously is a bad idea. What can I do to prevent this from happening? Here is the error log entries from when it crashed: Oct 13 01:30:23 2010 mailmanctl(19680): No child with pid: 3683 Oct 13 01:30:23 2010 mailmanctl(19680): [Errno 3] No such process Oct 13 01:30:23 2010 mailmanctl(19680): Stale pid file removed.

Large list and delivery concerns
by Andrew Hodgson Nov. 11, 2010

Nov. 11, 2010

Hi all, Ok, I have dealt with several Mailman lists in the past, however, all have been relatively small number of subscribers (around 60 subscribers being the limit, with around 2-3 messages per day). However, I have now taken on a list of around 350 subscribers receiving around 10-20 posts a day, and wonder what the most efficient way is to send the messages? I am currently using the default of Mailman sending out the message to the MTA (default Debian Exim on localhost) as one message with lots of recipients. Is it best to fan out these deliveries into more than one message by changing SMTP_MAX_RCPTS and using more than one connection by changing SMTP_MAX_SESSIONS_PER_CONNECTION? Any other suggestions? It has gone well so far, the only issue being initially blocked by Yahoo mail servers, however, I am dealing with this separately. Thanks. Andrew.

Redundant Mailman servers
by John Wingenbach Nov. 10, 2010

Nov. 10, 2010

Hi, I am trying to set up redundant/parallel mailman servers. In order to accomplish this, I will have 3 servers which run mailman on them. One server at a time will be determined to be the "admin" point. However, all three will enable distributing email to the pertinent lists. Obviously, archival of the mail to the lists is not enabled or supported. ADMINSERVER -> points to one of SERVERA, SERVERB or SERVERC Email to the lists gets sent to any of SERVERA, SERVERB or SERVERC (MX distributes to all 3 servers). Configurations from ADMINSERVER are to be sync'd to the other 2 servers. The problem I am running into is that when I duplicate the lists to the other servers, the lists which are "advertised" on the current admin server do not show up as advertised. However, config_list shows the lists as advertised. I am duplicating the following files across the servers: /var/lib/mailman/data/aliases /var/lib/mailman/lists/* What am I missing such that /mailman/admin will display the same set of advertised lists? Thanks, John

However, the above messages, presumably from Mailman's vette log, come from two different PIDs. Thus, I'm guessing that you are approving these messages via the admindb web interface, and something is going wrong in that process resulting in the message being discarded by the admindb CGI itself. > BUT if messages are sent by senders as mentioned in [Sender Filters] / > "List of non-member addresses whose postings should be automatically accepted" > THEN messages are delivered (of course without the necessity of approval). > > Since the vette-contents is rather concise, I editted > IncomingRunner.py'sErrors.DiscardMessage as follows, according > a earlier posting about this subject: > syslog('vette', 'Message discarded, msgid: %s, handler: %s', > msg.get('message-id', 'n/a'), handler) > but to no avail. Nothing changes in the output-format. Because the message is not discarded by IncomingRunner. It is discarded by the HandleRequest method in Mailman/ListAdmin.py called from Mailman/Cgi/admindb.py. > Since all our lists suffer the same problem, a generic > configuration error may be assumed, but I've no idea > how to fix it. Any hint would be gratly appreciated. Have you modified admindb.py in any way? Does the web admin interface work? What Mailman version is this?

What Causes Random Unsubscribe Notices
by David Andrews Nov. 4, 2010

Nov. 4, 2010

I run mailman with about 175 lists, and 6000 users, many of whom belong to multiple lists. I have personalized e-mail set to yes, and the following in the footer which produces a personal options link for the user in each message: To unsubscribe, change your list options or get your account info for %(real_name)s: %(user_optionsurl)s Several times a week I get mail from a user saying they got an unsubscribe confirmation message and hadn't done anything to trigger it. I believe them because I have gotten some too. This behavior seems to have started when I started adding personalized footers. Is it somehow caused by the long string of personalized links left in messages when people reply and don't trim off bottom. Some of these message chains can get pretty long. Or, is there something else that causes the generation of seemingly random unsubscribe confirmation messages?

non-delivery to virtual domain
by David Newman Nov. 4, 2010

Nov. 4, 2010

(Apologies for re-raising a topic I asked about here a couple of years ago. The instructions on Sourceforge have changed a bit since then.) New server runs OpenBSD 4.7, postfix 2.65, mailman 2.1.14, and virtual domains. Mail sent to/from virtual domains works fine. Different story with Mailman. Although postfix says a message addressed to a list is "sent" to all addresses, subscribers from virtual domains on this server do not receive the message. Subscribers on other domains not on this server do receive the message. There's no indication of trouble in the Mailman logs or in maillog. I've followed the setup instructions here, doing section 6.1.2 before 6.1.1 (given the link about doing virtual stuff first): http://mailman.sourceforge.net/mailman-install/postfix-virtual.html http://mailman.sourceforge.net/mailman-install/postfix-integration.html I've pasted the config files below.

Message text not showing up in digests or archives - Skipped content of type multipart/alternative
by Carl Shuller Nov. 4, 2010

Nov. 4, 2010

A sporadic number of messages in digest and archives are showing up with out the original message text and instead "Skipped content of type multipart/alternative" is showing up. I did a search and found a few others had experienced this problem some years ago but there wasn't any real follow up to the original posts, none that were helpful anyway. I was hoping folks on this list might have some insights. Thanks so much. Carl

Frequent use of clone_member
by Ivan Fetch Nov. 2, 2010

Nov. 2, 2010

Hello, We are changing student email from mailboxes, to forwarding addresses. Among other challenges, we are exploring various ways to deal with students who are subscribed to closed (only subscribers may post) mailing lists. (There are a lot of similar challenges when switching to an email forwarding model - any list members who have gone through this, I would love to pick your brain!) One possibility we're exploring, is to change a student's mailing list subscriptions, when they change their forwarding address. We would iterate through these address changes and run clone_member, like: Clone_member --remove --admin old(a)our.domain new(a)outside.domain We could end up processing as many as 500 address changes nightly (running clone_member for each one), with each run of clone_member iterating through all mailing lists. I'm concerned that this is much more than clone_member was intended for. Can Mailman developers or heavy uses of Mailman comment on this? Thanks very much, Ivan.

Sounds to me like you should make it a priority to get your servers communicating with your UPS's to perform safe shutdowns for extended power outages?
