[Help] MailScanner detect spam bot or not?

Post by hzwn101 »

I have a mail server that configured with mailscanner and spamaassassin. Lately, I have received a kind of bot attack of email which the sender send an email to multiple recipient( >100) in a short time.

One of my rule in spamassassin is to detect any sender in which is sending to more then 20 person as high scoring spam value.
However, since the attack is a private 1 to 1 mail, my rule cant hit that behavior.

Im asking is there any other way in trying to catch this style of attack using mailscanner and spamassassin?

Using Centos as my OS.
