Hi,
I noticed this happened (bounce.log):
Jul 09 12:46:51 2022 (71506) Member xxxxx@xxxxx.force9.co.uk already scored a bounce on list users.mailman.bitfolk.com today. Jul 09 12:46:51 2022 (71506) Bounce message for a non subscriber: Email users-leave@mailman.bitfolk.com is not a subcriber of users.mailman.bitfolk.com Jul 09 12:46:51 2022 (71506) Member andy@bitfolk.com on list users.mailman.bitfolk.com, bounce score = 1. Jul 09 12:46:51 2022 (71506) Bounce message for a non subscriber: Email users@mailman.bitfolk.com is not a subcriber of users.mailman.bitfolk.com
What happened here is that a reply to one of my posts was rejected by subscriber xxxxx@xxxxx.force9.co.uk at smtp time (Exim mainlog):
2022-07-09 12:46:13 1oA9qc-007qOx-0T ** xxxxx@xxxxx.force9.co.uk R=dnslookup T=remote_smtp H=mx.avasin.plus.net [212.159.8.200] X=TLS1.2:ECDHE_X25519__RSA_PSS_RSAE_SHA256__AES_256_GCM:256 CV=yes DN="businessCategory=Private Organization,jurisdictionOfIncorporationCountryName=GB,serialNumber=03279013,C=GB,L=Sheffield,O=Plusnet plc,CN=mx.avasin.plus.net": SMTP error from remote mail server after end of data: 552 Spam Message Rejected
The message contained my email address (andy@bitfolk.com) in quoted text, since it was a reply to a message of mine, and also contained addresses from the list's footer, which accounts for the log messages about users-leave@mailman.bitfolk.com and users@mailman.bitfolk.com.
I'm concerned that Mailman seems to have scored my address as bouncing even though it isn't, merely because it appears inside a message that was rejected.
Is that expected? Is there any way to avoid it?
I see that Mailman has a bunch of heuristics to parse bounce messages. In this case though, there shouldn't have been a bounce message received to users-bounces@, as this was an SMTP-time rejection. Mailman seems to have parsed addresses out of the actual mail it was sending, rather than only scoring the subscriber address it was trying to send a list posting to.
Cheers, Andy
