[Mailman-Users] News to Mail gateway setup

We needed the same thing, for pretty much the exact same setup. 
You'll need to change the source code to do this. It isn't that 
difficult, assuming that I've done this right:

In the "Handlers" directory of the "Mailman" directory, there is a 
file called "Hold.py". This is the script that determines whether or 
not a message needs to be held.

There is a section in there that says:

In it, there is a section that says:

     if mlist.member_posting_only:
         posters = Utils.List2Dict(map(string.lower, mlist.posters))
         if not mlist.IsMember(sender) and \
            not Utils.FindMatchingAddresses(sender, posters):
             # the sender is neither a member of the list, nor in the list of
             # explicitly approved posters
             hold_for_approval(mlist, msg, msgdata, NonMemberPost)
             # no return


Change this to:

     if mlist.member_posting_only:
         if mlist.gateway_to_mail:
             needgroup = mlist.linked_newsgroup
             newsgroup = msg.getheader('newsgroups')

         posters = Utils.List2Dict(map(string.lower, mlist.posters))
         if not mlist.IsMember(sender) and \
            not (mlist.gateway_to_mail and needgroup and 
newsgroup==needgroup) and \
            not Utils.FindMatchingAddresses(sender, posters):
             # the sender is neither a member of the list, nor in the list of
             # explicitly approved posters
             # nor is it from the gatewayed newsgroup
             hold_for_approval(mlist, msg, msgdata, NonMemberPost)
             # no return

Note that this still has some problems: if there is more than one 
newsgroup on the Newsgroups: line, the posting will still need 
approval (this could be considered a feature, of course). And the 
code does not check in a case-insensitive manner. I tried 
newsgroup=string.lower(msg.getheader('newsgroups')) and that 
generated errors in the error log for some reason. (I'm fairly new to 
python; this is, in fact, the first thing I've done in it.)

The above changes the code so that if the group's "gateway_to_mail" 
option is set, it checks to see if the message has a "Newsgroups:" 
header set to the same thing as the list's linked_newsgroup setting. 
If so, it lets the message through.
