As you state above "spamassassin is not very fast...."  which I'd think 
makes it a natural to set a max size of the raw msg to be parsed by SA 
which avoids rocket science.

the truncate and/or continue with bytes may not always work for spam and 
may add to the load by scanning unnecessary large HAM and it seems to me 
its a trial & error method till one gets the spam_du_jour caught in a 
jungle of sizes, multiparts, etc, etc.

Though & wish: apply the VERY simple spamc method: "max msg size" and 
save lots of cpu time and potential FPs avoiding scanning even chuncks 
of oversized msgs.
(incidentaly scanning chuncks breaks some plugins, full & rawbody rules, 
etc)


Expecting to be tarred and feathered by old MS users.....
