RE: Anti-Virus Anti-Spam

Roger, have you considered letting Sonicwall do AV in addition to your
desktop AV?  Let the Sonicwall AV engine catch most things.  If it gets
past that then the desktop AV can catch it.  That way if one AV engine
isn't current enough to catch something hopefully the other will be.
Desktop AV still has responsibility for things that don't originate from
email, of course.  If it's a good design then scanning for AV won't add
that much overhead to the Sonicwall; it should be able to do a single
pass over each incoming message to check for spam, phish, and virus.

We security people love layered defenses. :)
