? 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.

[ANNOUNCE] Mailman 2.1 alpha 2
by barry＠digicool.com 25 Mar '02

25 Mar '02

This the official announcement for Mailman 2.1 alpha 2. Because it's an alpha, this announcement is only going out to the mailman-* mailing lists. I'll make two warnings: you probably should still not use this version for production systems (but TIA for any and all testing you do with it!), and I've already had a couple of bug fixes from early adopters. 2.1a2 should still be useful, but you might want to keep an eye on cvs and the mailman-checkins list for updates. I am only making the tarball available on SourceForge, so you'll need to go to http://sf.net/projects/mailman to grab it. You'll also need to upgrade to mimelib-0.4, so be sure to go to http://sf.net/projects/mimelib to grab and install that tarball first. To view the on-line documentation, see http://www.list.org/MM21/index.html or http://mailman.sf.net/MM21/index.html Below is an excerpt from the NEWS file for all the changes since 2.1alpha1. There are a bunch of new features coming down the pike, and I hope to have an alpha3 out soon. I'm also planning on doing much more stress testing of this version with real list traffic, and I'm hoping we'll start to get more languages integrated into cvs. Enjoy, -Barry -------------------- snip snip -------------------- 2.1 alpha 2 (11-Jul-2001) - Building o mimelib 0.4 is now required. Get it from http://mimelib.sf.net. If you've installed an earlier version of mimelib, you must upgrade. o /usr/local/mailman is now the default installation directory. Use configure's --prefix switch to change it back to the default (/home/mailman) or any other installation directory of your choice. - Security o Better definition of authentication domains. The following roles have been defined: user, list-admin, list-moderator, creator, site-admin. o There is now a separate role of "list moderator", which has access to the pending requests (admindb) page, but not the list configuration pages. o Subscription confirmations can now be performed via email or via URL. When a subscription is received, a unique (sha) confirm URL is generated in the confirmation message. Simply visiting this URL completes the subscription process. o In a similar manner, removal requests (via web or email command) no longer require the password. If the correct password is given, the removal is performed immediately. If no password is given, then a confirmation message is generated. - Internationalization o More I18N patches. The basic infrastructure should now be working correctly. Spanish templates and catalogs are included, and English, French, Hungarian, and Big5 templates are included. o Cascading specializations and internationalization of templates. Templates are now search for in the following order: list-specific location, domain-specific location, site-wide location, global defaults. Each search location is further qualified by the language being displayed. This means that you only need to change the templates that are different from the global defaults. Templates renamed: admlogin.txt => admlogin.html Templates added: private.html - Web UI o Redesigned the user options page. It now sits behind an authentication so user options cannot be viewed without the proper password. The other advantage is that the user's password need not be entered on the options page to unsubscribe or change option values. The login screen also provides for password mail-back, and unsubscription w/ confirmation. Other new features accessible from the user options page include: ability to change email address (with confirmation) both per-list and globally for all list on virtual domain; global membership password changing; global mail delivery disable/enable; ability to suppress password reminders both per-list and globally; logout button. [Note: the handle_opts cgi has gone away] o Color schemes for non-template based web pages can be defined via mm_cfg. o Redesign of the membership management page. The page is now split into three subcategories (Membership List, Mass Subscription, and Mass Removal). The Membership List subcategory now supports searching for member addresses by regular expression, and if necessary, it groups member addresses first alphabetically, and then by chunks. Mass Subscription and Mass Removal now support file upload, with one address per line. o Hyperlinks from the logos in the footers have been removed. The sponsors got too much "unsubscribe me!" spam from desperate user of Mailman at other sites. o New buttons on the digest admin page to send a digest immediately (if it's non-empty), to start a new digest volume with the next digest, and to select the interval with which to automatically start a new digest volume (yearly, monthly, quarterly, weekly, daily). DEFAULT_DIGEST_VOLUME_FREQUENCY is a new configuration variable, initially set to give a new digest volume monthly. o Through-the-web list creation and removal, using a separate site-wide authentication role called the "list creator and destroyer" or simply "list creator". If the configuration variable OWNERS_CAN_DELETE_THEIR_OWN_LISTS is set to 1 (by default, it's 0), then list admins can delete their own lists. This feature requires an adaptor for the particular MTA you're using. An adaptor for Postfix is included, as is a dumb adaptor that just emails mailman@yoursite with the necessary Sendmail style /etc/alias file changes. Some MTAs like Exim can be configured to automatically recognize new lists. The adaptor is selected via the MTA option in mm_cfg.py - Email UI o In email commands, "join" is a synonym for "subscribe". "remove" and "leave" are synonyms for "unsubscribe". New robot addresses are support to make subscribing and unsubscribing much easier: mylist-join@mysite mylist-leave@mysite o Confirmation messages have a shortened Subject: header, containing just the word "confirm" and the confirmation cookie. This should help for MUAs that like to wrap long Subject: lines, messing up confirmation. o Mailman now recognizes an Urgent: header, which, if it contains the list moderator or list administrator password, forces the message to be delivered immediately to all members (i.e. both regular and digest members). The message is also placed in the digest. If the password is incorrect, the message will be bounced back to the sender. - Performance o Refinements to the new qrunner subsystem which preserves FIFO order of messages. o The qrunner is no longer started from cron. It is started by a Un*x init-style script called bin/mailmanctl (see below). cron/qrunner has been removed. - Command line scripts o bin/mailmanctl script added, which is used to start, stop, and restart the qrunner daemon. o bin/qrunner script added which allows a single sub-qrunner to run once through its processing loop. o bin/change_pw script added (eases mass changing of list passwords). o bin/update grows a -f switch to force an update. o bin/newlang renamed to bin/addlang; bin/rmlang removed. o bin/mmsitepass has grown a -c option to set the list creator's password. The site-wide `create' web page is linked to from the admin overview page. o bin/newlist's -o option is removed. This script also grows a way of spelling the creation of a list in a specific virtual domain. o The `auto' script has been removed. o bin/dumpdb has grown -m/--marshal and -p/--pickle options. o bin/list_admins can be used to print the owners of a mailing list. o bin/genaliases regenerates from scratch the aliases and aliases.db file for the Postfix MTA. - Archiver o New archiver date clobbering option, which allows dates to only be clobber if they are outrageously out-of-date (default setting is 15 days on either side of received timestamp). New configuration variables: ARCHIVER_CLOBBER_DATE_POLICY ARCHIVER_ALLOWABLE_SANE_DATE_SKEW The archived copy of messages grows an X-List-Received-Date: header indicating the time the message was received by Mailman. o PRIVATE_ARCHIVE_URL configuration variable is removed (this can be calculated on the fly, and removing it actually makes site configuration easier). - Miscellaneous o Several new README's have been added. o Most syslog entries for the qrunner have been redirected to logs/error. o On SIGHUP, qrunner will re-open all its log files and restart all child processes. See "bin/mailmanctl restart". - Patches and bug fixes o SF patches and bug fixes applied: 420396, 424389, 227694, 426002, 401372 (partial), 401452. o Fixes in 2.0.5 ported forward: Fix a lock stagnation problem that can result when the user hits the `stop' button on their browser during a write operation that can take a long time (e.g. hitting the membership management admin page). o Fixes in 2.0.4 ported forward: Python 2.1 compatibility release. There were a few questionable constructs and uses of deprecated modules that caused annoying warnings when used with Python 2.1. This release quiets those warnings. o Fixes in 2.0.3 ported forward: Bug fix release. There was a small typo in 2.0.2 in ListAdmin.py for approving an already subscribed member (thanks Thomas!). Also, an update to the OpenWall security workaround (contrib/securelinux_fix.py) was included. Thanks to Marc Merlin.

Of course you switch off Mailman's internal archiver. At least this gets the archiving hairball out of Mailman's pipeline. The HTML stuff is done by wilma (Web Interface to List Mail Archives), a front end to mhonarc and glimpse. I don't know anything about that, but could check out the configuration if you want.

Re: [Mailman-Users] Upgrading from 2.0b5 to 2.1a2

06 Nov '01

[Note: I'm moving this discussion to malman-developers. -baw] >>>>> "JAA" == Jose A Accino <jaccino(a)ieev.uma.es> writes: JAA> Is there any clean way to make a smooth upgrade from 2.0b5 to JAA> lates 2.1a2?

JAA> However, I've been unable to upgrade the old lists. Here are JAA> the main points: There's two ways to upgrade, neither of which has gotten a lot of testing. Based on you're message I tried the first way, and I'm about to check in a bunch of patches to make that go smoother. I'll try the second way soon. 1) Install a fresh virgin MM2.1 in /usr/local/mailman and then move lists from /home/mailman (MM2.0.x) to /usr/local/mailman. This way lets you migrate lists one at a time, gaining confidence in the new system in measured increments. I will probably upgrade {python,zope}.org this way. 2) Install MM2.1 overtop an existing MM2.0.x installation and have everything just magically work. I'll probably upgrade wooz.org's production lists this way. Both ought to work, and ought to be easy. After the checkins, here's a recipe that makes #1 easy: - Do a fresh install of MM2.1 in /usr/local/mailman according to the instructions. - Copy or move `mylist' by first moving /home/mailman/lists/mylist to /usr/local/mailman/lists/mylist and /home/mailman/archives/private/mylist.mbox to /usr/local/mailman/archives/private BTW, I used rsync for this, just cause it's a cool tool and I can actually remember how to invoke it with the right options. :) That's it. Everything else should just work, except for possibly two minor complications. - If your web server is going to support both installations, it's possible you'll have two different base urls, one for your MM2.0.x installation and one for your MM2.1 installation. If so, you'll need to manually change each moved list's web_page_url attribute. Fortunately, I'm about to add a script called `fix_url' which will reset a list's web_page_url to mm_cfg.DEFAULT_URL. So if you configure mm_cfg.py correctly, then run fix_url, you should be golden. I.e. % bin/withlist -l -r fix_url mylist - Same dealie with your MTA, i.e. your wrapper aliases may point to two different directories. Here, because I use Postfix and glued them together as described in README.POSTFIX, all I needed to do was run bin/genaliases and the new list aliases got installed. I'm sure that if you use Exim and glued them together as per README.EXIM, you probably don't need to do anything. (I'm still waiting on contributions for better gluing instructions for Sendmail, qmail, and any others.) -Barry

Bug in mail->news gateway in 2.0.5 (and *simple* fix)
by "Jürgen A. Erhard" 20 Oct '01

20 Oct '01

Bug: in Mailman/Handlers/ToUsenet.py, there are spaces inserted after colons where they are missing ("NNTP is strict about spaces after the colon in headers"). If a colon appears in a continuation line, it is treated as a header colon. Fix: skip lines that start with whitespace. For those interested, the history of the finding of the bug: Problem: my signed emails appeared on Usenet garbled. The multipart boundary had an extra space inserted (which of course the actual boundaries hadn't). After some exchange with Martin Armstrong (who made me aware of this) we concluded it had to be the mail->news gateway (as my direct mail to him, also signed, wasn't garbled). I then investigated ToUsenet.py, and found the error. Why this hasn't hit a lot more often is simple: most MUA seem to use some random gibberish as the boundary string. SEMI doesn't... Of course, if this is fixed in 2.1, you can ignore this (assuming that it comes out soonish ;-) Bye, J -- Jürgen A.

privacy problems with web interface
by Federico Grau 12 Oct '01

12 Oct '01

Hello: We're running a 16K member mailing list on version 1.1 and running into a significant privacy issue regarding membership management. As distributed, Mailman makes it trivial to discover if a given address is in fact a subscriber. If you suspect dev(a)null.com has joined a list, go to the user page and enter his address to subscribe; you'll get back a revealing reply 'You already belong, dummy'.. We initially yanked large chunks of html from the general list information page, but that removes all web-based user options. Our ideal outcome is a General List Info Page with two actions: No password section: Current users get passwords (if any) mailed; with the web page not saying if any address is subscribed or not. If not a subscriber, Mailman would send a "subscription confirmation" notice to the potential member. (This also alerts the 'victim' of potential abuse.) Password presented sections: Users w/ password see no feedback until after entering a valid ID and pw; i.e. both non-existent users and existing ones w/bad pw's are both met with "Sorry, wrong password" as in a *nix login. We looked at modifying the html on the user pages but the python module "handle_opts" seems hard-coded into giving revealing responses. We also glanced at Mailman 2.0.6 but it seemed to offer the same behavior. Has anyone else already looked into this issue, and proposed code to solve it? We are considering writing a patch for "handle_opts" and and submitting it but 1) don't want to fork the code, and 2) don't want to duplicate/waste the effort. thanks, David and Federico

[PATCH] Port HyperArch/pipermail to mimelib
by Ben Gertzfield 12 Oct '01

12 Oct '01

Here's a port of HyperArch and pipermail to mimelib. This allows proper parsing of multipart messages, and will make i18n handling much easier. This is a big step forward, I think, because now we no longer have two very different Message classes in Mailman. This patch depends on the mimelib patch I just sent; it uses the get_decoded_payload() function I added to get a nice text representation of even a multi-part message. This will let us even display a message for non-text parts of a message, and eventually will let HyperArch display attachments inline. And of course, as I mentioned in my previous mail, this will prevent base64 gobbeldygook from showing up in the archives. This patch even deals with multiple text/* attachments to a message, and will include them all in the archive even if they're base64 or quoted-printable encoded. It currently does not deal with replacing high-ASCII characters with HTML entities in HyperArch; I'm going to deal with that next by taking the htmlentitydefs module's hash, inverting it, and using that as a big global search-and-replace, if the charset is undefined or iso-8859-1. You can see an example message with lots of mixed parts in my pipermail archive, at: http://nausicaa.interq.or.jp/pipermail/test2/2001-September/000025.html (The original message that produced this output is available at: http://nausicaa.interq.or.jp/~ben/mime-test.txt) . This also patches pythonlib/mailbox.py to use mimelib instead of rfc822. This is the last use of rfc822 in Mailman, so we can now remove pythonlib/rfc822.py completely from the archives -- now we use mimelib entirely! Patch follows, against current Mailman CVS.

(2.0.6) pipermail takes >1 minute to rebuild indexes on large lists
by Ben Gertzfield 12 Oct '01

12 Oct '01

On a massive list (Mailman 2.0.6) I run that regularly gets a few hundred or more emails every day, things begin to slow down to molasses after a week or two each month, with the qrunner process taking literally HUNDREDS of megabytes of RAM, and 100% CPU, all the time. It's gotten so bad that the pipermail databases have gotten massive: -rw-rw-r-- 1 list list 40866061 Sep 13 19:24 2001-September-article -rw-rw-r-- 1 list list 686273 Sep 13 19:24 2001-September-author -rw-rw-r-- 1 list list 561479 Sep 13 19:24 2001-September-date -rw-rw-r-- 1 list list 796534 Sep 13 19:24 2001-September-subject -rw-rw-r-- 1 list list 569238 Sep 13 19:24 2001-September-thread And, of course, pipermail takes over a *MINUTE* to rebuild the indexes now. This is with a bunch of syslog() debugging in pipermail.py. Notice the timestamps -- this is how long it takes a *single* message to make it through the ToArchive step of the pipeline.. Sep 13 19:24:02 2001 (29357) in pipermail._update_simple_index() now Sep 13 19:24:02 2001 (29357) opening index as stdout Sep 13 19:24:02 2001 (29357) done opening index, writing index header Sep 13 19:24:02 2001 (29357) getting article 200109010000.JAA26551(a)admin.interq.or.jp from db Sep 13 19:24:03 2001 (29357) writing index entry 0 Sep 13 19:24:03 2001 (29357) going to next entry (snip LOTS of index entry writing -- note the timestamp and the count below) Sep 13 19:24:52 2001 (29357) getting article 3B95AB3EA.4F08HONDA(a)192.168.1.190 from db Sep 13 19:24:52 2001 (29357) writing index entry 4794 Sep 13 19:24:52 2001 (29357) going to next db Sep 13 19:24:52 2001 (29357) calling self.write_index_footer() Sep 13 19:24:52 2001 (29357) in pipermail._update_thread_index Sep 13 19:24:53 2001 (29357) in pipermail.write_TOC() Sep 13 19:24:53 2001 (29357) done writing TOC Sep 13 19:24:53 2001 (29357) picking archive state into /var/lib/mailman/archives/private/sysadmin/pipermail.pck While it does this, the size of the python process that's doing the qrunner grows by *megabytes* each second. I've seen it get to 200MB before it finishes, and it's always taking up 99% CPU. As you can guess, things rapidly get out of hand, and messages start arriving faster than pipermail can deal with them. And since it's first in the pipeline, nothing gets delivered until pipermail archives the mail.. and mail queues up and queues up, until it's taking 7-8 hours to send out each mail -- no joke. What can I do to help solve this? I know I can use an external archiver, but I don't know anything about that. I've commented out the ToArchive step from the pipeline for now, but I don't know what else I can do. There *MUST* be a way to not have to loop over every single article in the simple index every time a message arrives, right? Other people must have run into this, and I'd like to know what I can do to only have to write the changed articles in the simple index.
