any real downside to setting maxsize to 600Kbytes?
I'm getting a small continual number of Asian spam coming in with
message sizes in the 400-500Kbyte range.
Obviously the default 250K size in spamc is too small and these drop
through the defenses.
Upping it to 600K typically pushes these spam into the 10+ score range,
but I'm concerned what impact that will have on our servers if I
defaulted to that. Is there a "rule of thumb" as to how much more
memory/resource such a change would make to a total system?
e.g. if it only means each spamd process took another 1Meg RAM each, I
would be quite happy. If it mean sometimes they will swallow 100M extra
RAM - then it probably isn't worth the hassle.

A lot will depend on the amount of mail you are processing. I've had
my Max size increased for quite a while now and have noted no adverse
effects. Mail numbers here are typically 3k+ a day so not a huge
amount.
The SA server runs on CentOS 64 with a 1.7 Athlon and 1 GB ram.
