Hello, I need your help. There have question about Scenes:
Add mailbox a and mailbox b to mailing lists c and mailing lists d, and send mail to mailing list c and mailing list d through mailbox b , among which a has received many mails sent by b, check the log and find: The file about path:/opt/mailman /var/queue/bounces has the content of retrying mail, but I turned off process bounces.Mailing list sends mail via exim, logs found in exim： 023-03-09 00:54:47 1pa4YR-001xk5-0y <= <> R=1pa4YM-001xje-1F U=exim P=local S=7672 T="Mail delivery failed: returning message to sender" from <>
I need more information. Even though the list isn't brocessing bounces, bounces will still be returned to the -bounces address and queued in /opt/mailman/var/queue/bounces. If they remain there, the bounce runner is not processing them. If the list's bounce processing is turned off, the bounce runner should just dequeue the message and discard it.
If multiple messages go to the list, something is returning them to the list posting address instead of the list-bounces address.
Yes, You are right, I found the real reason and found that someone intercepted the mail sent through the mailing list, and then reposted the mail to the mailing list, resulting in multiple sending of mail. I only need to add spf detection in mta.
Thanks Mark.
