You prolly didn't get many qmailers to respond, then... If it wasn't for SA & spam, my "original" mailserver (Cyrix 133Mhz, 128Meg RAM) would *still* suffice for our mail needs... :-/
We're an odd lot, tho... ;-)

Its hard to say --- memory usage for the automata varies based on the size and type of regexp. For regexp inputs that are primarily fixed strings, its about 10 bytes/character. Generating it may require more RAM, but that can be a one-time thing.
Oh, one-time gigs (once/nite/week/whatever) are no problem... Cron is my friend... ;-)

Can you disable network tests? AFAIK, memory usage for SA is high because it interleaves several emails while they block for DNS queries.
I _already_ have. I have all of my RBL checks in my qmail-smtpd startup, so anything RBL'ed doesn't make it past the SMTP conversation; so all I run are the local test, and I don't auto-whitelist, either...
As is, each SA process requires a minimum of 30M, but can expand to 95Meg! It doesn't take many of those to fill a Gig'O'Ram... :-O
... and spamd doesn't always listen to it's -m operator and starts more children than it should ....

Thanks for the reference. What is the email volume?
Last I checked (about a month ago), between 30K & 35K messages per day, incoming. I haven't actually gauged it lately, tho...
I also haven't gauged the percentage that's actually coming into these mailboxen vs. the entire load...
I'd set up MRTG again, but I don't even run a webserver daemon on the box anymore, for fear of memory usage... :-/
Anywho, gotta blast. Thanks, Roger "Merch" Merchberger
