RE: Transparent Anti spam and virus web/mail/ftp Proxying on a Bridge

Hi, 

Stop for a while and think that with any kind of filters, will be some traffic delays. So I think, instead of any 
solution do you will adopt one or more machines for every kind of filters will be needed (one for SMTP, and another for 
http and ftp).

We use a CA eTrust Secure Content Manager for SMTP only (ant spam and email virus analyze) installed on heavy machine.

Subject: Transparent Anti spam and virus web/mail/ftp Proxying on a Bridge

Hello everyone.

I am interested in setting up a bridge to check all web, mail and ftp traffic for viruses and spam.  Setting up the 
bridge is the easy part, but I'm wondering if any of you all could give recommendations on what proxy applications may 
be useful.

I am planning on using ClamAV for the virus checking, and will use either SpamAssassin or Dspam as well for spam.  
DansGuardian looked valid as did PCScan for web and pop3 proxying, but would appreciate any ideas you all could share.

Thanks all.
