Title: Re: [Mailman-Users] News to Mail gateway setup

I've got News to Mail gatewaying working, almost.  Currently, whenever
someone posts to the news group, the post to the mailing list requires my
approval.  Is there some way to automatically approve posts to the mailling
list from the news group short of allowing anyone to post to the mailling
list?  I only ask because the news group I'm gating is not public, and I

assume the uni would like to keep it that way...

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.
