Quite possibly - and I agree, but I am currently "lazy", thus removing ClamAV 
since it had fewer "hits" than SA does in my logs is the most logical choice 
for me (in terms of least work required) at the moment.  I would rejoice at the 
ability to remove SA from my system however, as the mere thought of depending 
on a Perl program with hundreds of uncompiled RE's makes my boy-bits hide.

I would have thought so too - and perhaps this is maybe just my config for 
ClamAV, but I found it to appear to be using more cpu power than SA was when 
scanning messages... at least I think that's what I remember (might have been 
memory - but I'm fairly sure it was using more of at least one of the two than 
SA was).  In either case however, I would ultimately really prefer to have Exim 
running alone - not really requiring the aid of any 3rd party programs to 
perform message scanning.  I haven't had the time or opportunity however to do 
anything more than think of how nice it would be.

That statement is extremely intriguing.  I would be interested (if it's not a 
company secret) in learning what measures you take within Exim's config to 
block out most of your unwanted email.  As I stated just earlier - if I could 
ultimately remove my last dependency of SA from Exim, I would be a happy man.

Eli.
