[Mailman-Users] creating list defaults and filters?

FAQ 4.38 <http://www.python.org/cgi-bin/faqw-mm.py?req=show&file=faq04.038.htp>
might help with this. I could've sworn there was an FAQ relating to
how to make 'cookie-cutter' lists, as it were, but I can't seem to
find it. This info might just be in the list archives.
What you want to do, in this case, is set a header_filter_rule that
accepts anything with [announce] in it, and then set the default
action to be discard.

However, it sounds like you're trying to set up an umbrella list. An
easier solution here would be to have the umbrella list sender address
(e.g., announce-bounces at example.com) be in the
'accept_these_nonmembers', and set generic_nonmember_action to
discard. If necessary, you can further set all members of the list to
moderated, and set member_moderation_action to 'discard'.

There are mm_cfg.py settings for some list defaults, but not all.

There are settings for DEFAULT_ARCHIVE and DEFAULT_MAX_MESSAGE_SIZE.
See the sections "# Archive defaults" and "# List defaults" in
Defaults.py for a list of what's available.


In header filter rules, first set one or more rules to match and accept
what you want to pass. Then set the last rule with a RE that matches
anything (e.g. simply '^' or '.') and an action of reject (or hold or
discard).

Yes, order matters, the first rule matched is the one that applies to
the message.

Which ones? Is there a list which defaults can be put there?

Read Defaults.py.

Anything that's set there can be overridden in mm_cfg.py (although as
noted there, some settings are for internal Mailman use and shouldn't
be changed).

Anything not in Defaults.py can't be meaningfully set in mm_cfg.py
unless you modify Mailman code to use it.
