They are telling you that there is a Gmane address which is a member of
your list that is how gmane receives messages posted to your list.
Well, I know that that is how it is meant to work BUT the post I asked
about shows a from address like some...@tormail.net . My mailing
list doesn't have anyone with that address on it.
When someone posts to your list on Gmane, Gmane sends that post to
your list with the envelope sender (SMTP MAIL FROM address) equal to
the Gmane address that's a member of your list.
That doesn't appear to be happening.
Mailman in turn checks every address found in any of the places listed
in the Defaults.py/mm_cfg.py setting SENDER_HEADERS, and if any of
these is a list member, the is considered to be from first member
address found.
Well, I don't know how it can find an address that doesn't appear to
be there. :-(
It is not clear to me whether this post was held as a post from a
moderated member or just went to the list.
He/she doesn't appear to be a member at all.
If it just went to the list
and you want it to be held, just set the mod flag on the subscribed
Gmane address and it will be held as a post from a moderated member.
It doesn't appear to be a subscribed address.
If, on the other hand, you want it treated as a non-member post, you
have to override SENDER_HEADERS in mm_cfg.py. The default setting is
SENDER_HEADERS = ('from', None, 'reply-to', 'sender')
which says places checked in order are the From: header, the envelope
sender, the Reply-To: header and the Sender: header. The None entry in
the above list refers to the envelope sender. If you just want to stop
considering the envelope sender and keep all the others, you would set
SENDER_HEADERS = ('from', 'reply-to', 'sender')
in mm_cfg.py. If you wanted to consider only the From: header, you
could set
SENDER_HEADERS = ('from', )
in mm_cfg.py (the comma and parens are significant here).
Note that this is a global setting and affects all lists in the
installation.
The problem is that this is on a hosted site so I cannot change the
main Mailman files.
IF I understand things correctly you/Gmane seem to be saying that
somewhere in the envelope header is the address of someone on my list.
Not necessarily in the 'from', 'reply-to', 'sender' areas.
Is that correct ?
In any case what does envelope header mean ? Does it mean in the
sender's header in areas other than 'from', 'reply-to', 'sender' ?
In any case it looks like changing things in the SENDER_HEADERS in
mm_cfg.py will enable me to better restrict posters to those on my
registered posters list and/or make it so that posters have to put
their approved address in eg. the 'from', 'reply-to', 'sender'
slots, so to speak.
So can I make this change via my GUI in Windows XP ?
If you/anyone else here can give me an answer to this question, and
give me a step by step as to how to change things via windows, it
will be appreciated.
Regards, John.

Ah ! Gmane's subscription address ? If I put the mod flag on that then every poster would effectively be moderated wouldn't they ? Though your next paragraph suggests that that wouldn't happen. Given what you've said about your list configuration, if you set the mod flag on the Gmane subscription address and not on your actual list members you should see that posts via Gmane From: a list member will go directly to the list but posts via Gmane from a non-list-member will be held for moderation. This is because, at least in a default Mailman installation, we look first at the From: header in deciding if the post is from a member and next at the envelope sender. In the case of a member post via Gmane, the From: will have a member address and we will see this as a post from that (unmoderated) member. In the case of a non-member post via Gmane, the From: address will not be a member so we look at the envelope sender which is a member and which now is moderated so the post is held for moderation. What you need to do is go to the web admin Membership List pages for your list and find the Gmane address that is a member of your list and make sure its mod box is checked. That way, any non-member posts from Gmane, regardless of who they are From: should be held for moderation and you can accept them or not as you see fit. Okay, so I put the Gmane subscription address as mod ? I think that will accomplish what you want. Note that if the only mod address is the Gmane address, you can if you wish set Privacy options... - Sender filters - member_moderation_action to Reject and set member_moderation_notice to something like Posting to this email list via Gmane is restricted to members of the list. The downside of doing this is backscatter. I.e. if a spammer posts to your list via Gmane, the From: header probably contains the address of an innocent third party so you don't really want to reject the spam back to the innocent person who knows nothing about it. I would be more inclined to set member_moderation_action to either Hold or Discard, and if Hold, to Discard held messages that I didn't want to accept unless they clearly weren't spam. You said in your original post that your list was moderated. What does that mean to you? It means that people not on my mailing list should not be able to have emails go to the mailing list or the Gmane newsgroup. Aaahh.. To me, that is a closed list whereas a moderated list is one where all posts require approval by a moderator. -- Mark Sapiro m...@msapiro.netThe highway is for gamblers, San Francisco Bay Area, Californiabetter use your sense - B.

[Mailman-Users] MAIL FROM envelope header query.
Hi, I have a Mailman 2.1.14 *moderated* list that goes to Gmane for newsgroup access. The other day a post was made from someone who didn't appear to be on my list. I wasn't sure whether this was due to an error at my end, or at Gmane's. So I queried them. The problem however is that I didn't understand their reply but more importantlyhow to fix things so it doesn't happen again ! Can someone here read the following and tell me if/how I can put a stop to people not on my mailing list, posting please ? When Gmane sends messages (posted through the news-to-mail gateway) to the mailing lists, it uses the subscribed email address as the MAIL FROM envelope header. If your mailing list software discriminates based on the MAIL FROM instead of the From: header (the latter is more usual), then you may see stuff like that... I have been using Mailman for a time, but still consider myself a newbie, so any help on this would be appreciated.
