Hi I have recently be added to the cbl blacklist twice saying that something using my mailserver is sending spam, as I have a lot of external users on this server I can't figure out who it is , is there any way I can make the server scan outbound email as spam as well as inbound and bounce back the message if it's detected so users can't send spam through my server

Thanks
A

Re: Scan outbound mail

iRedMail enables spam/virus scanning for outgoing mails by default.

The possible cause is someone's weak password was cracked and used to send spam. Try script 'find_top_sasl_usernames.sh' in iRedMail-0.9.3/tools/ to find the top sasl usernames, do any users seem suspicious?
