Anyone have any experience raising that limit? How high can we go before
it really starts to impact performance? I realize this question contains
the big variable of 'how good is my CPU?', but I figure there might be a
'trip point' for SA, like when a message gets larger than 25% of
physical memory on the box, or some other simple guideline like that?
I run it at 400k on a VM with 256MB RAM and haven't seen problems. But
then, my email volume is quite low and I have zen and HELO FQDN checks at
SMTP time, which cut the majority of the garbage coming in.
