Can someone please give me some recommendation on good anti-spam measures / applications to use on Windows2008 + MailEnable? The server runs Enkompass control panel.
I have RBL's enabled: Barracuda Reputation Block List Spamcop SpamhausZEN
I also have greylisting enabled.
What else can I do, or which other anti-spam applications work well for Windows 2008 + MailEnable?
