From: "motty.cruz" on 29 Mar 2010 12:23 Hello, Lately I had been getting bounce email ( spam), I do not know how to effectively proceed to solve this problem. Below is the actual email that one of the users is getting constantly, the spam filer is unable to detected. The administrator said we can't do nothing other than create a rule in outlook to trash this email. Anybody have other suggestions, please? I'm using postfix+amavisd-new to combat spam.
