My server handling outgoing traffic of 2 lakhs = 200,000 (max) emails per day .
Some time due to virus infection or password hacking , spammers are sending many thousand of email within short time. Which at the end causing to blacklist my outgoing IP spool. I am using rate limiting ,strong password etc ... but still due to such issues business is getting disturb.
Want to is there any paid / opensource spam database available which will scan the outgoing email traffic ( not incoming ) from LAN / Wan and that can be integrate within MailScanner + Spamassassin or only with postfix MTA ? Which can detect and block the bulk / spam emails in realtime and have Low false positive rate .
What is best practice others are following for such scenario ?
