It arrived via SMTP on the loopback interface, perhaps you need to look earlier in your logs to see where a message with ID: <[email protected]> really came from.
it appears to be going back to gmail rather than being intercepted and processed by mailman.It isn't "going back" it is passed to some sort of LMTP service on port 8024 ont the local machine (either a content filter or a mailstore frontend). Are you reading the logs you're posting? Do you understand what they're telling you, or are they just line noise as far as you're concerned?2026-02-06T10:33:49.471389-05:00 dap002 postfix/smtpd[185613]: 7304C500071: client=localhost[127.0.0.1] 2026-02-06T10:33:49.514414-05:00 dap002 postfix/cleanup[185615]: 7304C500071: message-id=<[email protected]> 2026-02-06T10:33:49.553836-05:00 dap002 postfix/qmgr[185296]: 7304C500071: from=<[email protected]>, size=10502, nrcpt=1 (queue active) 2026-02-06T10:33:49.632822-05:00 dap002 postfix/lmtp[185616]: 7304C500071: to=<[email protected]>, relay=127.0.0.1[127.0.0.1]:8024, delay=0.17, delays=0.09/0.02/0/0.06, dsn=2.0.0, status=sent (250 Ok) 2026-02-06T10:33:49.635083-05:00 dap002 postfix/qmgr[185296]: 7304C500071: removedRead these carefully, don't jump to conclusions, and ask about anything that isn't clear.I realize there are separate processes there but that is what comes out every time mail is received from gmail.That email isn't received from gmail. It is addressed to gmail, but is delivered to something else via LMTP. Perhaps a content filter and hence later to Gmail, or not...I'm not sure what causes mail to be intercepted by mailman but it must be a configuration issue. These are all generated automatically by the mailman install.If mailmain is the LMTP server on port 8024, your transport settings are broken, mail TO gmail should not be routed to that transport.
I guess it is back to the mailman forum for help.
Again these entries are all created by the mailman install. I am not knowledgeable enough to completely understand how it all works but changing things tend to break mailman. I guess for now this thread can be ended.main.cf: transport_maps = hash:/opt/mailman/mm/var/data/postfix_lmtpWhat is in that transport table?local_recipient_maps = hash:/opt/mailman/mm/var/data/postfix_lmtpWhy is the mailman transport table your (entire) local recipient table? Both of these are unwise, especially if you don't know what's in that table.relay_domains = hash:/opt/mailman/mm/var/data/postfix_domainsAgain, why?postfix_lmtp: # Aliases which are visible only in the @gmail.com domain. [email protected] lmtp:[127.0.0.1]:8024 [email protected] lmtp:[127.0.0.1]:8024 [email protected] lmtp:[127.0.0.1]:8024 [email protected] lmtp:[127.0.0.1]:8024 [email protected] lmtp:[127.0.0.1]:8024 [email protected] lmtp:[127.0.0.1]:8024 [email protected] lmtp:[127.0.0.1]:8024 [email protected] lmtp:[127.0.0.1]:8024 [email protected] lmtp:[127.0.0.1]:8024Why on earth would you put these entries there?postfix_domains: gmail.com gmail.comWhatever for? The solution to logs that read like line noise to you isn't a configuration that also reads like line-noise to everyone else. You need to read the Postfix book by Patrick and Ralf, and start with a default configuration that you evolve step by step, testing after each modest change before moving further, until it meets your requirements. Trying random tweaks won't get you there.
