Re: Bulk Mail Spamming

It's very possible that some mail accounts' passwords were hacked and used to send spams.
Try to use the "find_top_sasl_usernames.sh" script below to find which smtp user sent most emails, then it's the possible spammer:
https://bitbucket.org/zhb/iredmail/src/ … ail/tools/

Reset its password immediately, also clean up the queued emails  sent by this user.

Btw, do you have plugin "reject_null_sender" enabled in iRedAPD (/opt/iredapd/settings.py)?

Does my reply help a little? How about buying me a cup of coffee ($5) as an encouragement?
