I like this one better ... it shows the scan results.
http://wiki.apache.org/spamassassin/FilteringViruses

(Odd that the SA wiki's version is more complete than Clam's...)

There's also an SA plugin that can call ClamAV, see
http://wiki.apache.org/spamassassin/ClamAVPlugin

However, I highly recommend something that interacts at SMTP-time so
that a 500-series reject notice can be issued, letting the sender know
that the message wasn't delivered due to its virus/malware content (I
also feel this way about spam filtering).

Also note (and this is a current predicament on my own deployment) that
clamdscan (as well as clamav-milter, which is what I use) is incapable
of breaking some attachments out of emails; an EICAR test attached with
Thunderbird still gets delivered in all three of the above
implementations on my system.
