Bounce removal parameters default values
by Greg Stark Oct. 23, 2003

Oct. 23, 2003

I find I am being removed from mailman mailing lists left and right. I believe the default values for the bounce removal should be reconsidered. It's possible that you haven't had many users in my situation and so haven't really had a chance to tune these parameters on the low end yet. But they clearly aren't working for me at a few sites. My particular situation is that my site has seen fit to filter viruses by refusing delivery. This causes a bounce from the remote MTA every time someone sends me an Outlook virus. Why my site administrators felt this was necessary is a question for another day, it's not like I use Outlook or like my spam filters wouldn't have thrown these messages away anyways, but whatever. The net result is that some small fraction of messages to me bounce and list management software notices this. The only reason I became aware of the problem was because ezmlm also does this type of processing but it sends a warning message before removing users. It only removes you if the warning message itself bounces. In fact it sends two such warning messages and only removes the user if *both* bounce. This provides the user with a chance to react to the first message and fix the problem -- if they ever see the message. I could beg for a similar feature in mailman, but I'm not sure it's necessary. But I am sure it's necessary to tune the bounce processing parameters. The relatively few bounces I'm generating shouldn't be causing me to get removed when all the real messages are being delivered fine. It seems the legitimate messages that are correctly delivered should reset the count of bounces to 0. Reading the source it seems it has to see DEFAULT_MAX_POSTS_BETWEEN_BOUNCES such legitimate posts between messages. I'm fairly convinced this parameter should always be 0. If any successful delivery occurs the user should never be removed due to bounces. What I don't understand is how DEFAULT_MAX_POSTS_BETWEEN_BOUNCES relates to the parameters I see in the admin. None of the parameters in the admin corresponds to this. How is it calculated? -- greg

TMDA fronted Mailman v2.1 lists
by J C Lawrence Sept. 17, 2003

Sept. 17, 2003

Things have been a bit busy, but I've finally moved to v2.1.* and Exim4, and in the process have had to adapt my setup for fronting Mailman lists with TMDA and an external optional/controllable MIME processor (MimeFilter, can be turned off on a per-message basis by a custom header). If there's sufficient interest I'll update the HOWTO with the details. There's nothing really hard in the deal, just an excess of details. Interested? ObNote: If you don't know what I'm talking about, please see the UserFAQ and the archives of this list for definitions, implementation details and implications, and prior discussion of same. ObNote2: TMDA as of v0.75 (latest .deb)is not able to read Mailman v2.1 list configurations to extract the membership rosters (the pickle now contains bounce objects so the naive cPickle.load fails). This doesn't create a major problem, just means that you have to comment sections of your TMDA filters until that's fixed. (Jason: If you want example configs and other details, just give me the word and I'll attach them over). -- J C Lawrence ---------(*) Satan, oscillate my metallic sonatas. claw(a)kanga.nu He lived as a devil, eh? http://www.kanga.nu/~claw/ Evil is a name of a foeman, as I live.

RELEASED Mailman 2.1.2
by Barry Warsaw Aug. 18, 2003

Aug. 18, 2003

[Apologies for the empty dups -- been fiddling with my email client again. ;} -BAW] I've just released Mailman 2.1.2 which includes many bug fixes and language updates, as well as support for two new languages, Portuguese/Portugal and Polish. I recommend all Mailman 2.1 users upgrade to this release. The full source tarball has been made available from the usual sites. Currently, there is no patch available, but you should be able to install 2.1.2 over your existing 2.1.x installation. See http://sourceforge.net/project/showfiles.php?group_id=103 for links to download all the patches and the source tarballs. Be sure you restart your mailman daemon by doing a "mailmanctl restart" after installing. See also: http://www.gnu.org/software/mailman http://www.list.org (not yet updated) http://mailman.sf.net Cheers, -Barry -------------------- snip snip -------------------- 2.1.2 (22-Apr-2003) - New languages Portuguese (Portugal) and Polish. - Many convenient constants have been added to the Defaults.py module to (hopefully) make it more readable. - Email addresses which contain 8-bit characters in them are now rejected and won't be subscribed. This is not the same as 8-bit characters in the realname, which is still allowed. - The X-Originating-Email header is removed for anonymous lists. Hotmail apparently adds this header. - When running make to build Mailman, you can specify $DESTDIR to the install target to specify an alternative location for installation, without influencing the paths stored in e.g. Defaults.py. This is useful to package managers. - New Defaults.py variable DELIVERY_RETRY_WAIT which controls how long the outgoing qrunner will wait before it retries a tempfailure delivery. - The semantics for the extend.py hook to MailList objects has changed slightly. The hook is now called before attempting to lock and load the database. - Mailman now uses the email package version 2.5.1 - bin/transcheck now checks for double-%'s - bin/genaliases grew a -q / --quiet flag - cron/checkdbs grew a -h / --help option. - The -c / --change-msg option has been removed from bin/add_members - bin/msgfmt.py has been added, taken from Python 2.3's Tools/i18n directory. The various .mo files are now no longer distributed with Mailman. They are generated at build time instead. - A new file misc/sitelist.cfg which can be used with bin/config_list provides a small number of recommended settings for your site list. Be sure to read it over before applying! sitelist.cfg is installed into the data directory. - Many bug fixes, including these SourceForge bugs closed and patches applied: 677668, 690448, 700538, 700537, 673294, 683906, 671294, 522080, 521124, 534297, 699900, 697321, 695526, 703941, 658261, 710678, 707608, 671303, 717096, 694912, 707624, 716755, 661138, 716754, 716702, 667167, 725369, 726415

Re: [Mailman-Developers] Mailman password and administrative reminders
by Dan Mick Aug. 14, 2003

Aug. 14, 2003

? This very message came to me with the following header: Errors-To: mailman-developers-admin(a)python.org All my bounces come to the list admin address, set in the admin webpage, in the second field of General Options. Do you have that set to something, and bounces still come to root? > 2. Bounces are sent to the poor postmaster instead of a -admin address. > I'm not entirely certain, but I think an Errors-To: header or something > like that in all Mailman messages might allow one to distribute that load > somewhat.

Bugs in Mailman 2.1.2

Mailman 2.1.2, Apache 1.3.27, and Python 2.2.2: On initial configuration, on attempting to create the mailman list itself, the output from newlist mailman is: To finish creating your mailing list, you must edit your /etc/aliases (or equivalent) file by adding the following lines, and possibly running the `newaliases' program: ## mailman mailing list mailman: "|/var/lib/mailman/mail/mailman post mailman" mailman-admin: "|/var/lib/mailman/mail/mailman admin mailman" mailman-bounces: "|/var/lib/mailman/mail/mailman bounces mailman" mailman-confirm: "|/var/lib/mailman/mail/mailman confirm mailman" mailman-join: "|/var/lib/mailman/mail/mailman join mailman" mailman-leave: "|/var/lib/mailman/mail/mailman leave mailman" mailman-owner: "|/var/lib/mailman/mail/mailman owner mailman" mailman-request: "|/var/lib/mailman/mail/mailman request mailman" mailman-subscribe: "|/var/lib/mailman/mail/mailman subscribe mailman" mailman-unsubscribe: "|/var/lib/mailman/mail/mailman unsubscribe mailman" Hit enter to notify mailman owner...

Minor comments and a possible bug on MM v2.1
by J C Lawrence June 30, 2003

June 30, 2003

1) The sliding/N'th_message pseudo-VERP supports rocks. 2) The new admindb interface is a significant improvement. 3) Forwarding messages from the admindb as message/rfc822 parts needs to be optional. Previously I used that feature support heavily to move messages between lists as a moderator as threads drifted. The use of MIME attachments now makes that a pain. 4) I have HOLD_MESSAGES_AS_PICKLES=0 in mm_cfg.py and seem to get occasional orphaned messages in ~mailman/data. There's a held-<listname>-* file there, but there's no entry in the appropriate matching data structures. I suspect a race condition as the three times this has happened have all been when I've had over 20 messages delivered to a single list within a couple seconds. 5) MTAs that send bounces to Return-path headers in messages rather than the envelope suck. -- J C Lawrence ---------(*) Satan, oscillate my metallic sonatas. claw(a)kanga.nu He lived as a devil, eh? http://www.kanga.nu/~claw/ Evil is a name of a foeman, as I live.

strange behavior with EXTERNAL_PUBLIC_ARCHIVER
by Jonas Meurer June 28, 2003

June 28, 2003

hello, i realized some strange behavior of mailman with the EXTERNAL_PUBLIC_ARCHIVER option. simply setting it to '/usr/bin/id > /tmp/log 2>&1' gives in /tmp/log: uid=38(list) gid=38(list) groups=0(root),102(lpadmin),109(shutdown) at commandline: $ whoami list $ id uid=38(list) gid=38(list) groups=38(list),106(lurker) why does user list member different lists in the two cases? same uid, same gid, only the lists it members are different. bye mejo -- Efficiency and progess is ours one more Now that we have the Neutron bomb It's nice and quick and clean and gets things done Kill kill kill kill kill the poor tonight

Excellent analysis Barry -- accurate and revealing. Short version of the results: The 2.1.2-2 Mailman package in /testing is broken in that it uses the floor operator, and yet the Python2.1 package shipped in /testing don't -- which means that the python2.1-email package in /testing fails to install properly due to you use of the floor // operator in _compat22.py. Solution: upgrade python2.1 to /unstable and make sure that the python2.1-email package is installed. Hopefully the Debian mailman maintainer will read this (I'll CC this to him later if he doesn't ack me here). > I hope to have time to spin 2.1.3 tomorrow. It would help me if we could squeeze the Return-Path fix in there. TMDA requires a Return-Path header and the work-arounds for the Mailman/TMDA integration are ungraceful. I won't have time today, and likely not tomorrow either alas. If you could delay a bit I can likely do it in the early days of this week. BTW I may finally be able to buy you some of those beers I owe you. I'm on a consulting gig in Groton CT these days (a long and dismal story).
