Take a look at the following links - I use something based on thisthis for spam filtering and it works better than any other free or commercial product I've tried. I don't use the antivirus portion (I have a separate system for that).
Like others have said, this mail scanning should probably be done on some host other than your firewall. It would ideally be done by whatever host your MX record is set to. Think of it as a separate email firewall. This sort of stuff is fairly CPU intensive, especially if it's for a large group of users. http://www.flakshack.com/anti-spam/wiki/index.php http://flakshack.com/anti-spam/wiki/index.php?page=FairlySecureAntiVirusWiki -----Original Message----- From: Siju George [mailto:[EMAIL PROTECTED] Sent: Tuesday, June 06, 2006 2:05 AM To: Smith Cc: [email protected] Subject: Re: popular mail & squid virus scanning technique for openbsd On 6/6/06, Smith <[EMAIL PROTECTED]> wrote: > I once posted that all the anti-virus checking should be done on the > Windows boxes only.
