My setup is as follows: I host mailman3 list server which uses our mail server as a relay.The spam emails i.e [email protected] and [email protected] are neither members nor non members of the lists which are generating the bounces.I have also confirmed that none of the list members are forwarding to any of those spam addresses.What am I missing?Thank you. _______________________________________________ Mailman-users mailing list -- [email protected] To unsubscribe send an email to [email protected] https://lists.mailman3.org/mailman3/lists/mailman-users.mailman3.org/ Archived at: https://lists.mailman3.org/archives/list/[email protected]/message/OVTNBPLWJOXRWGBA4QLOU65OCESRVVCN/
