Not only that, but I would look into an alternative to qmail-scanner.
It's a great package (and the one I started using to do virus scanning way
back when), but the overhead of launching perl for each scan can be a
killer. This is especially true if your concern is about lots of messages
at once. I'd suggest looking at a compiled queue replacement program,
like simscan or qmail-scanner (I've used both - I currently use simscan,
but only because it's still being developed and I'd like to eventually use
it for spam scanning as well). Also, if you don't do the virus scanning
at the initial SMTP level, you end up bouncing viruses...
P.S. One last hint: put you scanning directory on a ramdisk - it speeds
things up a ton!
