? 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.

List of list admins
by Maryann Stopha 21 Mar '01

21 Mar '01

Hi, I need to get a list of all the admins for our Mailman system, and wondered if anyone could help me with this. I have tried to grep them out, but it has not worked with getting info out of the .db files. Does anyone know a simple way to accomplish this? Thanks, Maryann Stopha -- Web Development Professional Computing & Information Technology SUNY Geneseo 716.245.5577 stopha(a)geneseo.edu

There's a stupid, stupid bug in Mailman 2.0, which I've just fixed and (hopefully) unjammed things on the Mailman end[1]. We're still probably subject to the Postfix delays unfortunately; I think those are DNS related, and I've gotten a few other reports of DNS oddities, which I've forwarded off to the DC sysadmins. I don't think that particular problem will be fixed until after the New Year. relax-and-enjoy-the-quiet-ly y'rs, -Barry [1] For those who care: there's a resource throttle in qrunner which limits the number of files any single qrunner process will handle. qrunner does a listdir() on the qfiles directory and ignores any .msg file it finds (it only does the bulk of the processing on the corresponding .db files). But it performs the throttle check on every file in listdir() so depending on the order that listdir() returns and the number of files in the qfiles directory, the throttle check might get triggered before any .db file is seen. Wedge city. This is serious enough to warrant a Mailman 2.0.1 release, probably mid-next week.

Re: [Mailman-Developers] Installing on virtual server - info offered

Hi folks. I also appear to have solved most of the bugaboos, after trying about five or six different approaches (whew!). I'm still trying to get the Redhat cron to run qrunner correctly, but I'd like to compare notes. BTW, I would love it if there were some way to separate the CGI prefix from the MTA and admin script prefix - this makes it tough to install on virtual machines. I spent the morning browsing the code to figure out how it all works and eventually try to spot a way to do it. It'd be lovely and wonderful to just edit a mailman.conf file and have everything work automagically; that way it'd be much easier to create new virtual Mailman installations whenever one creates a new host without rebuilding the package. I realize that right now, anyway, Mailman isn't architected that way, but one can dream... Thanks to everyone for a neat package! Happy New Year!

Installing on virtual server - info offered

Hi, I wanted to run Mailman on a virtual web hosting account, namely on a Cobalt RaQ. I didn't find any advice in the mailing list archives, only a couple of other people asking how. So I disregarded the "You will need root access on the machine hosting your Mailman installation" in the README, had a go and (modulo a few hoops jumped through) appear to have succeeded. As a contribution to the community I would like to write up some notes on what I did, and make them available. Can you suggest where and in what form would be the best way to do that? Maybe a wiki or faqomatic where others can add their own input / caveats etc? Regards, -- Colin Hogben

Off-line for a while :(
by Barry A. Warsaw 28 Dec '00

28 Dec '00

Hello all, As of 6pm last night, my old DSL line was finally yanked, so I'm effectively off-line. (I'm writing this from Guido's house via a web interface to corporate email -- tedious and a whole state away so I won't be doing this too often.) I /think/ I have my new line ordered with a different ISP, but of course that starts me back at ground zero in the DSL game. As soon as I get confirmation, I should at least have dial-up in the interim. The upshot is that my email reading over the next week or so will be sporadic at best. I shouldn't lose any email, so it's fine to keep sending stuff and discussing MM3.0 issues. I'll catch up when I'm back on-line. On the plus side, I sucked down a lot of s/w before my line went down, so I've got plenty of fun stuff to hack on, and no email to distract me. :) Remember, Python was originally written during the week b/w Xmas and NY, so who knows /what/ Mailman will look like on the other side. :) Cheers, -Barry

Users, Bounces, and Virtual Domains (was (no subject))
by Dave Klingler 22 Dec '00

22 Dec '00

It occurred to me that I could provide a little more information in case someone else wants to do what I've done in using virtual domains with mailman. I left out a few steps in my synopsis below. If anyone wants me to post a more complete recipe, let me know. I'll put up better instructions once I figure out what's wrong with what I've done. I DID put a symbolic link to /home/mailman/mail/wrapper in my /etc/smrsh directory so that smrsh could find the wrapper file. I left that out below. I THINK that wrapper runs okay, but when I su to mail and then run it with "wrapper mailcmd test" I get "sh: wrapper: command not found". I'm guessing that means wrapper can't find its way to the scripts directory, but I'm not sure why not, or whether that's the problem that causes sendmail to deposit the missive "operating system error" in my queued mail files. All in all, if it only worked it'd be Really, Really Elegant. No, really. Dave Klingler > 1.

Re: mail processing module
by Barry A. Warsaw 22 Dec '00

22 Dec '00

I've been working on a new package for dealing with message objects, including mime messages. Mostly this is for use in Mailman, but they will be generally useful. I want to eventually replace essentially what's in rfc822.py, multifile.py, mimetools.py, and taking some of the best ideas of stuff like mimecntl.py. The basic idea is that I've separated the object model from parsing and generating. That way you can drop in different parsers or generators, and you can manipulate the object model independently. Conceptually a message object has a set of headers and a payload. The payload can be just a string or a message object, or a list of those. Then you can add/remove headers with semantics similar (but slightly different) to rfc822, and you can add/remove payload objects. You pass a root message object to the generator, and it spits out text suitable for delivery via smtplib.py. It knows that message objects w/ list payloads are multiparts. The parser on the other hand, takes text and spits out a message object tree. parsing->object tree->generator is idempotent. For composition, there is a base class that knows about content-type: headers, and subclasses for common subtypes (image/*, text/*, etc.). Cool things you can do with this are: take a mime message, find the image subparts, rip them out and post them to a webdav server, replacing the image/* part with a text/* part that contains just a url to the image; throw away all binary subparts, reordering the containing multipart, etc. etc. It's not complete right now and I won't be able to post anything until I get back my internet connection, but stay tuned. It'll be distrib'd as a distutils package so it'l be easy to install. I'm just not sure what to call it (always the most important thing to decide. :) The two I've come up with so far are "pantomime" and "mimeo". Cheers, -Barry
