I currently evaluating a system to scan our email for Viruses and Spam. 
I'm using Postfix and plan on using Amavis. I would like to hear about 
your experiences with Virus/Spam scanners. Any suggestions would be 
greatly appreciated.

I would prefer to us an open source solution like Clam Antivirus or 
Open Source Antivirus. Has anyone used these scanners and what do you 
think?
