AntiVirus for sendmail

["Orpheus" <orpheus@metempsychosis.com>]

hiya.

does anyone have any opinions for the best combination of a sendmail and
antivirus solution for 3.2 (current or stable)? this is for a home network
of basically 3 computers and i'm not to keen on $600 AUD + for RAV or
Vexira, plus I'd like some opinions on how they go
(stability/effectiveness/etc.) in the wild.

I currently use F-Secure for my XP machines and am very happy with it ...
looks like their gateway AV is only for Linux though, so I'm not confident
with compile issues..

Any comments greatly appreciated, & all the best for the new year
