What do you prefer
(a) Questions to which you can answer "that's the way the SpamAssassin 
developers recommend it"
(b) User boxes which are grinded to their knees when big mesages arrive.

Remember that *every* mail is scanned in the first place, also you PHB's 
mail with those multi-meg presentation slides or you friend's cool holdiay 
photos. At peaks, SpamAssassin needs about four to ten times the memory of 
the original message. And also remember that KMail is still completely 
useless while any filters with external apps run.

Right, and the recommended basic setup is not to scan big messages, the 
limit randomly chosen at 250k which is already pretty heavy. Whoever wants 
to shoot himself in the knee can indeed change that limit to something 
else.

No, not really :)

spamc has a default limit of 250k built in, overridable with the -s switch.  
The spamassassin script, which (if I may say that again :) is not the 
recommened way running SpamAssassin on a daily basis, doesn't have any size 
limits. This will probably change for 3.1, but currently it relies on the 
user too feed it only reasonably sized mail.

Cheers,
Malte
