me getting OT:

btw:  since stable "only" has security fixes, how much will a current 
(upstream)  ClamAV, SpamAssassin e.a. will drift away from stable? What 
i mean: security fixes won't install new scan engines (does this occur 
in "real world"?), but only programming errors, or maybe some scanning 
patterns, too. So, won't i be forced in time to change a stable system 
(which is what i want in poduction environment) to a mixed system with 
testing or sid? Which would/could cause update problems and potentially 
instabel or (more) insceure system? Won't aging of these scanning tools 
render them quite worthless?

How do YOU deal with this? Suggested Readme's, HowTo's? Is there some 
missconception in my mind?

ps: still rampant learning curve ahead, for running mailserver; don't 
yet use clamav/sa
