List, We are evaluating a few products for gateway virus scanning. I am very happy about Sybari Antigen for SMTP in general. But I just saw GFI Mailsecurity, and it looks a very competitive product. However, I am not able to get much feedback on the product. Can you experts give your feedback on GFIMS. How does it perform when compared to NAI Webshield, Symantec and Sybari ? Regards, Raj
