  What's the legitimate use case for multiple From headers?

Technically, there is none.  RFC 5322 requires exactly one From field,
and that's that.  http://www.ietf.org/rfc/rfc5322.txt, table in
section 3.6.  (Resent-From, of course, is a different kettle of fish.)

However, presumably multiple addresses in the From field (same URL,
section 3.6.2) would have the same effect on Mailman's (current)
filtering strategy.

Actually, I think MM3 could handle either case:

field_values = self.get_all(header, [])
senders.extend(address.lower() for (real_name, address)
   in email.utils.getaddresses(field_values))

Re: [Mailman-Users] Automating Mailman Archive Maintenance

[C Nulk]

I agree with you, Mark.  Unfortunately, as you may know, my Python
skills aren't the best.  I am working on little bits of improvements for
us here as time permits so I use the tools with which I am most familiar.

Since we are using Mailman v2.1.9, we are a bit behind where Mailman
currently sits.  Your gracious help assisted us with the LDAP plus I
have made some custom modifications - one you help with was for Special
Posters and a set of changes to add more logging information to the log
files.  At some point, we will be migrating to at least v2.1.12 or
later, so I need to look at incorporating my mods into the later code.
And very little free time to do it.

Thanks again for you help,
Chris

P.S.  While my automation php app isn't the best written thing in the
world, if anyone wants a copy to use as a starting point for conversion
to a Python script, let me know.

 I don't have any way to check on any locks.  Afterwards, I can restart
 Mailman, then call the script to rebuild the archives.

 That should work fine, but if you wrote a Python script, it could use
 Mailman list methods to manage the archive locking and use either
 Python's imaplib or mailbox modules to actually manipulate messages in
 the .mbox.
