Mark, thank you for your reply. Yes, the hostname variable for the list is correct. The posting emails from the list are delivered correctly.
I now think this is due to a spam email which was sent to mail...@mydomain.com (it's stuck in my mail queue) which is somehow erroneously being processed by mailman and routed to this particular list's owners, but with a bad sender address. Does this seem plausible? I see a "mailman" list in /etc/aliases and ../mailman/lists, but there isn't a "mailman" list in my web config. I did dump the configuration for the "mailman" list via config_list and hostname is set correctly. > -----Original Message----- > From: Mailman-Users [mailto:mailman-users- > bounces+nwyman=viablecomputing....@python.org] On Behalf Of Mark > Sapiro > Sent: Wednesday, November 01, 2017 10:34 AM > To: mailman-users@python.org > Subject: Re: [Mailman-Users] New list's SMTP failures > > On 11/01/2017 07:41 AM, Nick Wyman wrote: > > > > On a server which hosts several mailman lists, a new list is exhibiting odd > behavior for owner email addresses.
