No. As MailScanner only starts up the virus scanning engine once for each
*batch* of messages, rather than for every message (which is how certain
products I could mention do it), Sophie doesn't actually help. It also
increases a single point of failure. If Sophie dies or locks up, what can
MailScanner do about it? MailScanner is designed to be as robust as
possible. My MailScanner servers run for months on end with no intervention

MailScanner can happily handle completely different settings for thousands
of domains at the same time. This can all be done on a per-domain, per-user
and per-just-about-anything-you-can-think-of basis.
How you choose to arrange your mail system is entirely up to you. Get your
sendmail/Exim configuration working the way you want it, then simply
install MailScanner over the top of it. No changes required at all.

MailScanner doesn't deliver mail or provide SMTP service itself, there are
already other packages that are very good at that (e.g. sendmail and Exim).
I don't do anything which would be better done elsewhere, it results in a
far more robust system.

The only open source virus scanning engine is Clam. My opinion of that is
improving :-)
One of the cheapest and one of the better commercial scanning engines is
F-Prot, as they and RAV charge per *server* instead of per *user*.
