Yes, we understand that those logs are normal. And indeed we have a list called "mailman"... Could that be confusing the software somewhere??
I doubt it.
Note that the log excerpt posted at
https://lists.mailman3.org/archives/list/mailman-users@mailman3.org/message/...
only shows the handling of a message sent from
snap_wl-bounces+mailman=caltech.edu@caltech.edu. The envelope sender is
VERPed and indicates that this message was intentionally sent to
mailman@caltech.edu. I.e., when the snap_wl list created this message
it intended it to go to mailman@caltech.edu.
The thing is that we have a pretty convoluted setup for handling mailing lists messages, but it's always the same for all messages. That's why we don't understand why only a small fraction of all the moderation messages get misdelivered at random times for random lists.
I think what Dan was getting at is: Are there any other logs that would show us how a message that:
a) was accepted by Postfix on the Mailman server for local delivery to list-owner@lists.caltech.edu;
b) was therefore piped into the Mailman software;
But according to the header excerpt I quote at
https://lists.mailman3.org/archives/list/mailman-users@mailman3.org/message/...
it isn't sent directly from Postfix to Mailman's LMTP runner. It gets
there via ec2-12-34-56-78.us-west-2.compute.amazonaws.com
I think that's where the issue occurs. It appears that isn't even on the Mailman host, the no Mailman logging is going to help.
c) came out of that processing as needing to be now delivered (remotely) to mailman@caltech.edu, rather than the actual address of the owner of the original list?
Or maybe we can turn on more verbose logging or something?
PS: Not to confuse things (because it doesn't apply in my example), but what happens when a list has no owner and a message is sent to list-owner?
Mail to list-owner is resent by Mailman to the list owners and moderators. If there are no owners or moderators the message goes to the configured site_owner https://gitlab.com/mailman/mailman/-/blob/master/src/mailman/handlers/owner_...
