We spent allot of time researching this for the first client, and when 
we went to do the second, it seemed too easy.

As others have mentioned, both clamv and amavis are in extras.

Here are the relevant lines from my postfix main.cf:

content_filter = lmtp-amavis:[127.0.0.1]:10024
lmtp-amavis   unix    -       -       n       -       8       lmtp
smtp-amavis     unix -        -       n     -       8  smtp

It should be pretty obvious which lines go in which section.

The idea is that both inbound and outbound email are passed through the 
virus checker.

amavis will use the clamv database for checking.

As I recall, the default /etc/amavisd/amavisd.conf does this.

clamv may need a bit of tweaking for email reports, but thats about it.

Once you verify the postfix is working, you can remove the sendmail 
packages.

The guys who rolled the packages of clamv, amavis and postfix for FC6 
did a good job.

Good luck!
