Quick, your bias is showing... ;-)

There are many ways to use Perl so that it is lightweight (in terms of 
performance, since RAM is cheap).  For example, *all* of the inbound 
email to the apache.org and perl.[org|com] domains is handled by 
qpsmtpd, which is an advanced MTA written in Perl.

The next generation qpsmtpd will be capable of handling tens of 
thousands of simultaneous inbound connections (currently used only for 
spamtraps).

FULL DISCLOSURE: I am one of the developers of qpsmtpd.

You apparently didn't read very closely; the main project hasn't had a 
recent *official* release, but one of the contributors has been 
continuing to develop (and his last released code in the 1.1.2 series 
was Mar 28, 2006 and in the 1.2.0 series was today).

Did you make sure to update the ClamAV definitions?  Did you make sure 
that you configured ClamAV correctly (e.g. to scan inside archives)?  A 
quick test done without understanding the tools involved is equivalent 
to no test at all.
