I found that the version that came with Red Hat 9.0 wouldn't work for me (ie I couldn't upgrade to it) so I stuck with the 7.2 version (2.0.13) till the end of Red Hat 9 support. We are now running the 2.1.5 version that comes with Fedora but running it on Red Hat Enterprise Linux (RHEL). I did however have to recreate all the lists by hand in an overnight shift (what fun that was...) a few days before leaving the country (hence the rush). At that time I didn't know I could export the configuration (Doh!). Red Hat have taken some packages out of RHEL eg arpwatch and mysql-server (although this is in the "extras" channel) even though these are in the source RPM. Mailman is currently not included but might be being put back in to RHEL 4.0. I would like to hope so, as I find 2.1.5 far superior to 2.0.13. -- John Airey, BSc (Jt Hons), CNA, RHCE Internet systems support officer, ITCSD, Royal National Institute of the Blind, Bakewell Road, Peterborough PE2 6XU, Tel.: +44 (0) 1733 375299 Fax: +44 (0) 1733 370848 John.Airey(a)rnib.org.uk To truly believe in Evolution requires complete faith that life has no meaning.

Long question: list management library?
by Sean Vickery 30 Jan '05

30 Jan '05

Dear Mailman developers, By way of introducing myself, I'm a small-time programmer and former Unix systems engineer. I used to focus on email systems (Sendmail & majordomo), web (Netscape & Apache), DNS (BIND), usenet news, etc. I intend to development an announcement-subscription and management system for the Queensland Peace Network <www.qldpeace.org>, a community organisation I do IT work for. I envisage a system more sophisticated than a simple mailing list to satisfy the peculiar needs of our organisation and potential subscribers. Would anyone here have some information on email lists management libraries that they could provide me? I'm interested in libraries (freeware or commercial) that do all or some of the following: - User subscription and unsubscription requests - Subscriber web interface to change options (I'd be extending this heavily .. I hope this will be the essence of my project) - Sending emails to subscribers and handling the consequent bounces (RCPT ORCPT= & DSN support would be highly desireable). - VERP probing of bouncing users Clearly Mailman has some fairly sophisticated code to do all of this. How tightly coupled is that code to the rest of Mailman? Are there any 'unpackaged' libraries there might be to perform these functions? Regards, Sean Vickery.

Re: [Mailman-Developers] SMTPDirect timeout
by Thien Vu 29 Jan '05

It should but the MTA we're connecting to is a load balancer, and this is a known issue with our load balancer vendor (the backend goes down but the load balancer doesn't terminate the connection), but this could happen for a variety of other reasons. I chose to do this rather than SO_KEEPALIVE because the socket interface isn't really exposed through the smtplib module.

Currently if the pattern in acceptable_aliases has any upper-case only characters in it, it won't ever match.

29 Jan '05

I put together a tarball for Mailman 2.1.6 beta 1, but unfortunately SourceForge's file upload machine is out of disk space. For now you can get the file from: http://www.list.org/mailman-2.1.6b1.tgz I'll get that uploaded to SF as soon as possible. Huge thanks go out to Tokio Kikuchi for all his great work on this release. -Barry

[Fwd: Mailman tutorial]
by Barry Warsaw 28 Jan '05

28 Jan '05

Jack Jansen sent the following message to me, but I will not be able to attend. I still think it would be a great idea though, and Jack said it would be okay to forward this message to this mailing list to see if anybody else would be willing to sign up for giving a Mailman tutorial at this conference. Time is short though -- the deadline is (officially) January 31st. If you think you'd be able to give this tutorial, please let Jack know (and CC me). Thanks! -Barry

Admin-controlled rejection text...
by Brad Knowles 28 Jan '05

28 Jan '05

Folks, I've been doing a bit of hacking on Mailman. The issue is that if you set member_moderation_action to be Reject instead of Hold, you can supply a nice little bit of text in member_moderation_notice, or you can let the system supply a standard text for you. My problem is that I want to leave member_moderation_action set to Hold, and set the generic_nonmember_action to be Reject, but still supply my own text. Let's look at how these two are handled differently. First, member_moderation_action, has the following lines in Mailman/Handlers/Moderate.py, starting at line 59: if mlist.getMemberOption(sender, mm_cfg.Moderate): # Note that for member_moderation_action, 0==Hold, 1=Reject, # 2==Discard if mlist.member_moderation_action == 0: # Hold. BAW: WIBNI we could add the member_moderation_notice # to the notice sent back to the sender? msgdata['sender'] = sender Hold.hold_for_approval(mlist, msg, msgdata, ModeratedMemberPost) elif mlist.member_moderation_action == 1: # Reject text = mlist.member_moderation_notice if text: text = Utils.wrap(text) else: # Use the default RejectMessage notice string text = None raise Errors.RejectMessage, text elif mlist.member_moderation_action == 2: # Discard. BAW: Again, it would be nice if we could send a # discard notice to the sender raise Errors.DiscardMessage else: assert 0, 'bad member_moderation_action' # Should we do anything explict to mark this message as getting past # this point? No, because further pipeline handlers will need to do # their own thing. Okay, I don't know Python, but I can kinda follow that. Notice how the value of "text" is modified depending on whether or not member_moderation_notice is empty or not, and how this code directly raises the error instead of calling a subroutine. Now, let's consider what happens with generic_nonmember_action. We have the following lines in Mailman/Handlers/Moderate.py, starting at line 101: # Okay, so the sender wasn't specified explicitly by any of the non-member # moderation configuration variables. Handle by way of generic non-member # action. assert 0 <= mlist.generic_nonmember_action <= 4 if mlist.generic_nonmember_action == 0: # Accept return elif mlist.generic_nonmember_action == 1: Hold.hold_for_approval(mlist, msg, msgdata, Hold.NonMemberPost) elif mlist.generic_nonmember_action == 2: do_reject(mlist) elif mlist.generic_nonmember_action == 3: do_discard(mlist, msg) Note how this does very little other than decide which subroutine to call, then call it. No check is made for member_moderation_notice, nor is any specific rejection text supplied. Let's take a look at do_reject(), starting at line 136: def do_reject(mlist): listowner = mlist.GetOwnerEmail() raise Errors.RejectMessage, Utils.wrap(_("""\ You are not allowed to post to this mailing list, and your message has been automatically rejected. If you think that your messages are being rejected in error, contact the mailing list owner at %(listowner)s.""")) This creates a hard-coded message with a %()s substitution, and sends that out. Now, am I missing something here, or should we not be calling do_reject() in each of these cases and having just the one canonical "raise Errors.RejectMessage", and passing this routine a string to be used as the rejection notice, or allowing it to decide to fill one in for us in the case that we provide "None"? Okay, so I modified do_reject to at least check the value of member_moderation_notice and to use that text, if it is non-empty. Here's what I've now got: def do_reject(mlist): listowner = mlist.GetOwnerEmail() text = mlist.member_moderation_notice if text: text = Utils.wrap(text) else: # Use the default RejectMessage notice string text = Utils.wrap(_("""\ You are not allowed to post to this mailing list, and your message has been automatically rejected. If you think that your messages are being rejected in error, contact the mailing list owner at %(listowner)s.""")) # Reject this sucker raise Errors.RejectMessage, text This works. Well, mostly. I'd be submitting this as a patch and working on getting this put into production, if it worked completely. I know that what we should really have is a separate generic_nonmember_notice and have the routine check that instead, but I would be willing to take this as a small but significant improvement in the meanwhile. Problem is, while we can provide a %()s substitution ourselves in the text we feed to Utils.wrap, I can't do the same thing from member_moderation_notice. Instead, it simply outputs the literal string, and gives me "<" and ">" as opposed to the real less-than/greater-than symbols that I want to use around the URLs. I'm stumped. I don't even know what to search for in the archives of the mailman-users and mailman-developers lists. Can anyone here lend me a clue? -- Brad Knowles, <brad(a)stop.mail-abuse.org> "Those who would give up essential Liberty, to purchase a little temporary Safety, deserve neither Liberty nor Safety." -- Benjamin Franklin (1706-1790), reply of the Pennsylvania Assembly to the Governor, November 11, 1755 SAGE member since 1995.

SMTPDirect timeout
by Thien Vu 28 Jan '05

28 Jan '05

We recently experienced a problem with our smtp delivery where the connection is lost to the SMTPHOST which caused all the OutgoingRunners to lock up. There is no connection reset or anything so the connection appears to be ESTABLISTED and it just sits there. Eventually all OutgoingRunners are consumed in this state. The only reference I see to something similar to this happening is at: http://www.mail-archive.com/mailman-developers@python.org/msg07442.html The patch I've attached is a simple alarm around the SMTPDirect.py call into smtplib to terminate the connection after a configurable amount of time. Right now I have it set to minutes(10) but it's completely configurable via mm_cfg.py Any thoughts about this? Thien
