[Mailman-Users] umbrella lists

[Evilio del Rio]

Hello,

I was also looking for a solution like yours and I have been able to trick
a little bit the Mailman code.

The general solution is to allow the "posters" setting of a list to be a
regular expression so that you can allow some lists to receive mail from
an entire domain. Maybe this is not exactly what you are looking for but
it can help.

I put the following settings to all lists:

 posters = ['.+ at my.doma.in'] # Any address within domain can post.
 acceptable_aliases ="""allstaff at my.doma.in
 """

and then I have modified the Hold.py file
($prefix/Mailman/Handlers/Hold.py). The diffs are (you can use patch 
if you want to try):

32a33
> import re
120c121,123
<         posters = Utils.List2Dict(map(string.lower, mlist.posters))
---
>       isposter = 0
>       for poster in mlist.posters:
>               isposter = isposter or re.compile(poster,
re.I).match(sender)
122c125
<            not Utils.FindMatchingAddresses(sender, posters):
---
>            not isposter:


This way, anybody in my domain can post to any of the internal lists but
they are still closed to suscrbers+posters. However this is just a quick
hack and there should be another way to have "cascading closed lists".


HTH,
