Triggers for when lists are changed?
by Kelly Jones June 3, 2008

June 3, 2008

I run nightly cron jobs to fix/update various Mailman lists. I don't know Python, so I write Perl scripts that call the Python scripts in /usr/local/mailman/bin/ This works OK, but I'd really like to run these Perl scripts whenever a list is changed, not just once a day. In other words, I'd like Mailman 'triggers'. Examples: "whenever list foo's membership changes, run foo-member-change.pl" "whenever list bar's config changes, run bar-config-change.pl" "whenver anything changes on any list, run list-cleanup.pl" Can Mailman do that? If not, I'd like to request it as a feature. I realize I can have a daemon watch the config.pck timestamps, but that seems ugly. -- We're just a Bunch Of Regular Guys, a collective group that's trying to understand and assimilate technology.

Subscription errors
by Duncan Drury June 3, 2008

June 3, 2008

I have recently upgraded my Mailman installation to 2.1.10 and the online subscription system that I set up stopped working completely (users fill out a form, which generates an email, which subscribes them to the list). This seems to be related to the known bug in 2.1.10 and I have tried installing the patch that has been discussed in many places - but I am still getting the same problem. In log/error I am seeing the following: May 28 23:36:05 2008 (31672) Uncaught runner exception: 'NoneType' object has no attribute 'lower' May 28 23:36:05 2008 (31672) Traceback (most recent call last): File "/usr/local/mailman/Mailman/Queue/Runner.py", line 120, in _oneloop self._onefile(msg, msgdata) File "/usr/local/mailman/Mailman/Queue/Runner.py", line 191, in _onefile keepqueued = self._dispose(mlist, msg, msgdata) File "/usr/local/mailman/Mailman/Queue/CommandRunner.py", line 241, in _dispose res.do_command('join') File "/usr/local/mailman/Mailman/Queue/CommandRunner.py", line 139, in do_command return handler.process(self, args) File "/usr/local/mailman/Mailman/Commands/cmd_subscribe.py", line 74, in process if digest is None and password.lower() in ('digest', 'nodigest'): AttributeError: 'NoneType' object has no attribute 'lower' May 28 23:36:05 2008 (31672) SHUNTING: 1212014164.9099751+f202edd394843183ffbb4f3cde5b3f52fca1038a Perhaps I am not installing the patch correctly? I'm using the FreeBSD port of Mailman, and haven't had to patch anything before! Any help would be much appreciated. This has had me scratching my head for days. Duncan

Relative to Relaying deny
by JCSL June 3, 2008

June 3, 2008

Hi everybody I have a big problem with a list, I have installed in my server as MTA Postfix, an antivirus Vexira and mailman to have the posibility to get a service's list. I have 4 lists created, 3 of them contain only email's directions with my domain i mean is only for internal use, that's works perfect. But theres one that contain external domains and when i try to send a message to all the members (hotmail's, yahoo's, etc), the message never is delivered, checking the logs i found that error in the smtp-failure's log in mailman: May 27 18:29:15 2008 (7555) delivery to <a member's direction> failed with code 558: Relaying denied: domain not valid. I could send emails from my MTA to this domains, so i think that the configuration of my postfix is correct but....... when mailman try to send messages dosen't work. I hope that somebody could help me. Thanks in advance.... ======================= Julio César Serna Luna ____________________________________________________________________________________ Yahoo!

Re: [Mailman-Users] setting respond_to_post_requests and header filters in mm_cfg.py

The issue is that there seem to be no options in mm_cfg.py that reflect these settings. I can set all other things, but not these two... Florian

custom mime precedence?
by andReadG June 3, 2008

June 3, 2008

Hi all! This is the situation: attachments are stripped (which is as I intended), but many messages come in as multipart, with 1st part as text/plain and second one as text/html. The senders, intended to send the 2nd one (formatted to draw attention in specific parts), but, being treated as attachment, stays at the server. Is there a way around? I mean extract and keep all non-text attachments for http download, but exclude text/html and let it through along with the plain text, or be preferred over it? any help/suggestion will be greatly appreciated! tAndRead

archive/attachment preening
by Savoy, Jim June 2, 2008

June 2, 2008

Hi all, We have 870+ mailing lists and about 20 gigs worth of stuff in the private/archives directory. I thought I would do a little spring cleaning, such as sending mail to list owners to see if they still want their lists. But I would also like to pare down the size of the archives directory, which have been allowed to grow wild, using cron jobs. Before I do that, I want to get assurance from this list that I fully understand how the archives are written. We are currently running Mailman v2.1.5 and we'll upgrade to v2.1.10 later this summer. Please confirm the assumptions I am about to make before I write the preening scripts for cron. I also want to write a bunch of scripts that look for certain information. 1) If a list is digestable and archiving was never turned on, then the archives/private/listname/index.html will contain only the originally-created file (which basically says "No messages have been posted to this list yet, so the archives are currently empty"). 2) If there is no mbox file in the /archives/private/listname.mbox directory, then the list has never had archiving turned on. 3) If a list is digestable but there is no attachments directory in /archives/private/listname, then the list has never had a message posted to it. 4) If the list is digestable, and archiving has never been turned on, then files in the archives/private/listname/attachments directory are only useful to already-existing subscribers who have digesting turned on (ie if I poll a list and it has no members subscribed as digest users, then it is safe to delete all files in the attachments tree). If all of my above assumptions are correct, my psuedo-code would do something like this: if (list is not archived and has no digest members) keep stuff in attachments dir for 1 month; if (list is not archived but does have digest members) keep stuff in attachments dir for 1 year; if (list is archived) keep stuff in attachments dir for 3 years; For the archived lists (we have about 150 of them) I will contact the owners first, to warn them that I plan to pare their archive down to 3 years max. If they protest, I will add them as an exception to the rule and skip over them during the cron job run. I know that there is more to be done with regards to reducing the size of archives (ie running arch --wipe on the editted, pared down .mbox file, but I will do that manually). For now I am mostly interesting in keeping the stuff in the attachments directories to a minimum. I realize that deleting stuff in /attachments breaks links in the archive and digest messages, but I think that is reasonable for the really old messages (provided the list owner concurs). One final question. I know that you can change a list's settings with /bin/config_list, but can you poll a list for settings? For example, you can use "/bin/list_members -d" to see which members of a list read in digest mode, but how can I find out which lists have archiving turned on? Or do I have to examine the archives/private tree to garner that kind of info? Thanks! - jim -

sharing administrator passwords
by Laura Creighton June 2, 2008

June 2, 2008

Here's the situation: I site I know has several hundred mailman mailing lists. Most lists are administed by 2 or 3 different people. Most people who administer at least one list, administer 10 or more. It is a pain to remember all the list passwords, and people are complaining that it is insecure to have them all written down. On the other hand, it is politically impossible to give out the site password. So what people _want_ is a way to log in with a password and then have mailman recognise them and make it possible for them to administer all the lists they run. I don't see any way to do this. Am I missing something, or will this require code? Laura Creighton

high memory usage and long running time for mailman Python process
by Terrence Brannon June 2, 2008

June 2, 2008

Hello, I am running Debian/etch and the user "list" has a Python process which takes up 83.2% of my memory and has been running for more than 40 minutes. My suspicion is that some sort of queue of moderator messages is very large. In fact, /var/lib/mailman/ is very large... I cannot access the administrator interface via the web: 6733 ./qfiles 21551 ./messages 60071 ./lists/asciidoc-discuss 60093 ./lists 288500 ./data 380881 . In looking through archives, I discovered I have more than 60,000 held messages for one mailing list: schemelab@li2-168:/var/lib/mailman/data$ ls -l | wc -l 64688 but for some reason attempting to discard even one is not working... it just sits there and hangs: schemelab@li2-168:/var/lib/mailman/data$ sudo ../bin/discard heldmsg-asciidoc-discuss-59527.pck Password: (no return to shell after 5 minutes)

I did not know if the plus characters were >causing problems. I ran another test: 1) I set up an e-mail alias a+b(a)anl.gov that points to an existing test list on my test Mailman 2.1.9 system. 2) Via that test list admin web page, I added a+b(a)anl.gov to the acceptable_aliases list. This address is the only entry in the list. 3) I sent test mail to a+b(a)anl.gov and the mail was sent to the moderator (i.e., me) due to "implicit destination" I have not looked at the code, and I am not an expert in regular expressions. I surmise that Mailman is treating the address as a regular expression, which matches ab(a)anl.gov aab(a)anl.gov aaab(a)anl.gov aaaab(a)anl.gov ... but does not match a+b(a)anl.gov I then changed the acceptable_aliases to a\+b(a)anl.gov and test mail was distributed. ---------------------------------------------------------------------- Barry S.
