Antispam

[Marshall]

Hi,
I have two iMacs networked to a IBM Server running MS Small busines server and MS Exchange. I've tried using Symantec Brightmail on our server, but it's a waste of time and money.
So I'm looking for a good Mac version of Antispam software, can anyone recommend any.

Thanks
Marshall

The majority of my SBS clients, I have their mail handled by an SMTP smart host, which "washes" the mail for spam 'n viruses, and then spits it out to their Exchange server.
Google/Postini or Appriver are the common ones I use.

I use Postini. It's not perfect, but makes a huge difference in the volume of spam that gets through. And it's dirt cheap.
