There's a package called dns (I think the PyPI name is pythondns). A module called dns.resolver is imported in mailman/rules/dmarc.py which provides the DNS client.

The list it happens on has its Privacy options... -> Sender filters -> dmarc_moderation_action set to Discard. If that is not the case and "SpamDetect" processing is discarding some but not all messages for the same list, then perhaps it is not DMARC but header_filter_rules responsible for the discard. -- Mark Sapiro The highway is for gamblers, San Francisco Bay Area, Californiabetter use your sense - B.

[Mailman-Users] Occasional duplicate messages from a mailman list?
I have a list with about 25 members. One of the members on the list gets duplicate messages most of the time. And yes, the '.. no duplicate' option is checked for the list. My only clue is that sometimes one of the headers in replying to a message sent by the list has 'bounce' in it: From: tcr-owners on behalf of Shelley Brown What is generating the 'bounce'? All email addresses on the list have been checked for authenticity, and the option of sending 'bounces' to me (the admin) is checked and I don't routinely get any. thanks for taking a look at this post, Howard -- Mailman-Users mailing list -- mailman-users@python.org To unsubscribe send an email to mailman-users-le...@python.org https://mail.python.org/mailman3/lists/mailman-users.python.org/ Mailman FAQ: http://wiki.list.org/x/AgA3 Security Policy: http://wiki.list.org/x/QIA9 Searchable Archives: https://www.mail-archive.com/mailman-users@python.org/ https://mail.python.org/archives/list/mailman-users@python.org/

All list messages are sent with envelope from listname-boun...@example.com or in your case the VERPed address LISTNAME-bounces+RECIPIENT=recip.dom...@example.com. This is so bounces if any will be returned to that address where they can be automatically processed by Mailman. This has nothing to do with your duplication issue. Duplication can occur in various ways and is not always easy to diagnose. For example, I sometimes see duplication of mail from yahoo.com users. This is intermittent in my case and not related to particular senders or recipients and when it occurs it appears that two copies of the message get sent by separate yahoo.com servers to my incoming MTA, and I have never been able to understand why. In any case, diagnosing duplication requires comparing all the Received: headers in the two copies to determine where the duplication occurs. I think it's unlikely that this process will show that the duplication comes from Mailman, but it is possible. I think it is more likely that it occurs in your outgoing MTA or further downstream, but you first have to figure out where it occurs and if it's between Mailman and your MTA or between your MTA and the first hop recipient MX, your MTA's logs may have clues. If it's further downstream, there's probably nothing you can do about it. One other obvious but often overlooked possibility is the list member has some message filters set up locally that create the dup. -- Mark Sapiro The highway is for gamblers, San Francisco Bay Area, Californiabetter use your sense - B.
