question about scripts.
by Mike Lucas July 25, 2003

July 25, 2003

I was wondering is there is a good website with docs on the verious scripts that come with mailman? The ones I am currently working with are newlist, config_list and add_members. Mostly I am looking for a list of all the command line args for these and usage. Thanks, Mike

This sounds like an interesting opportunity to get some more Mailman exposure. I won't be able to attend, but if any of our UK or Euro friends are planning to, would you be willing to volunteer a little time at the booth? If so, please let me and Brian know (I don't know what all is involved, other than shouting at the top of your lungs every five minutes: "Mailman Rocks!" :) -Barry

mailpasswds is brittle
by Les Niles July 24, 2003

July 24, 2003

I just ran into a problem with the monthly password reminders. They haven't been going out on some of our lists for several months. I was able to ignore this for quite a while under the theory that it would be fixed when we upgraded from a beta to a final version of mailman. Then we did the upgrade and there still weren't any reminders. Turns out one of the lists has a subscriber who has no password entry; this causes mlist.getMemberPassword() to throw an exception which is not caught, which in turn causes mailpasswds to abruptly exit at that point. For some reason cron didn't email me an exception traceback when this happened, but that's another issue. Anyway, I figured the right fix was to make mailpasswds a little more robust. Here's a patch against the 2.1.2 version, to catch these and possibly other exceptions and report them a little more verbosely. -les les(a)2pi.org --------------------------------------------------------------------- *** cron/mailpasswds.orig Wed Jun 25 10:28:40 2003 --- cron/mailpasswds Wed Jul 23 11:25:25 2003 *************** *** 136,152 **** for mlist in byhost[host]: listaddr = mlist.GetListEmail() for member in mlist.getMembers(): ! # The user may have disabled reminders for this list ! if mlist.getMemberOption(member, ! mm_cfg.SuppressPasswordReminder): ! continue ! # Group by the lower-cased address, since Mailman always ! # treates person(a)dom.ain the same as PERSON(a)dom.ain. ! password = mlist.getMemberPassword(member) ! optionsurl = mlist.GetOptionsURL(member) ! lang = mlist.getMemberLanguage(member) ! info = (listaddr, password, optionsurl, lang) ! userinfo.setdefault(member, []).append(info) # Now that we've collected user information for this host, send each # user the password reminder. for addr in userinfo.keys(): --- 136,159 ---- for mlist in byhost[host]: listaddr = mlist.GetListEmail() for member in mlist.getMembers(): ! try: ! # The user may have disabled reminders for this list ! if mlist.getMemberOption(member, ! mm_cfg.SuppressPasswordReminder): ! continue ! # Group by the lower-cased address, since Mailman always ! # treates person(a)dom.ain the same as PERSON(a)dom.ain. ! password = mlist.getMemberPassword(member) ! optionsurl = mlist.GetOptionsURL(member) ! lang = mlist.getMemberLanguage(member) ! info = (listaddr, password, optionsurl, lang) ! userinfo.setdefault(member, []).append(info) ! except: ! err='mailpasswds: Exception %s (member %s, list %s): %s'%\ !

Bounce processing
by Juan Enrique Gómez July 23, 2003

July 23, 2003

Hi! I have been looking how works the bounce daemon, and i see thtat everytime it processes a bounce, it rewrites the list file complete, is this possible?, if so i think this is a crazyness cause in lists with 200k users, every bounce takes tooooo looong... thanks for the info.

dual processor & large list perforance issues
by Robert Anderson July 23, 2003

July 23, 2003

What sort of performance gains can mailman expect from going from a single processor to a dual processor machine? I'm considering going from a P4 2.0GHz machine to a dual 2.0 GHz Xeon system (also going from ide to scsi hdd). My question is will mailman make use of the second processor with different processes? Say one processor could be used for serious bounce processing and the other for subscriber / unsubscribe requests and other functions? Or will all the locking on list files etc. negate the extra processor? Second question/comments: My total subscriber base in as of today 219,829 (announce only) and it seems to be killing my current machine. I'd like to be able to scale up to over 3 or 400,000 if needed. Am I perhaps being unrealistic about mailman's abilities to handle this? An idea occurred to me that perhaps the only way to stick with mailman and process large lists could be to split the volume up over multiple boxes. Everything else seems to be able to handle around 200,000 subscribers except bounce processing (ie MTA can pump out the messages no problems). It has been suggested Fil at Rezo that pre-processing the bounce messages without opening the lists and then only post-processing the bounces against the real lists could improve performance. Is this in keeping with plans for 3.0 or any other planned future release? If a change like this is likely to be accepted into CVS would any other large list users be interested in assisting with resources for someone to make the changes and submit them back into the mailman project? >From an economics per perspective the cost of ownership of additional box's to run mailman amounts to $1000's of dollars annually. If through a number of interested parties all making a small investment we can cut down of the need for extra machines AND help make mailman a better system then we have a big win-win. Anyone interested in discussing this further on or off list with me would be appreciated (including anybody who might be interested in the contract to do the work or any ideas of the feasibility / time the change could make) -- Robert Anderson Managing Director Ecommerce Magic Ltd http://www.ecommerce-magic.com +64 21 808 525

Bounce & Virgin

July 23, 2003

Hi! I have been investigating on the performance problems with this two daemons when using very big lists (more than 100k members), and in the strace debug, it seems that everytime a bounce is scored the mailman rewrites the entire database for the list?, is working this way mailman?

bug in HTML parsing (in list archives)
by Robert Millan July 22, 2003

July 22, 2003

It seems that HTML links are not parsed properly by mailman for the list archives. In the following message (bug-grub): http://mail.gnu.org/archive/html/bug-grub/2003-07/msg00040.html There are two links but they point to the URL of the archived message itself instead of the real target of the link as intended by the mail author. -- Robert Millan
