Software-wise, I'd recommend sendmail with MimeDefang unless the postfix/mailscanner combo has a way to avoid starting a new copy of the scanners for each message.
MailScanner starts one copy of the scanners by batch of messages.
What does 'batch of messages' mean to a mail server? Or more relevant to performance, what kind of ratio of program starts to messages do you expect and can you sort-circuit the startups as soon as you know you are going to discard a virus?
MimeDefang runs as a sendmail milter that is always running and doesn't need to restart for each message so it is particularly efficient although spamassassin takes a certain amount of CPU to run anyway.
