Tere.
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).
Well, Ram is cheap but this isn't the main goal. Usually perl needs latest version, all kind of modules etc, and C based software does not. And I have no time to install all that stuff and most of all I have no time to even add more Ram if needed just like that, as servers are running 24/7 and only 4 minutes downtime per year is allowed:(.
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).
You right, I found there link to the latest version, did You mean - http://www.magicvillage.de/~Fritz_Borgstedt/assp/ which gives at this moment:
Internal Server Error

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.
Sure. ClamSmtp did catch some, Amavis did catch all, with identical settings and latest software/definitions, so I choose to use Amavis in future, as I did use it also previously, ClamSmtp was just a test purpose only.
