Hi,
I'm user of spamassassin to reviw a lot (a lot!) of incoming mails with spamassassin lot time ago. Today i have a machine just running spamassassin, due the high CPU and MEM requirements. Just to be clear (may be i have something bad).... The question is:
Q) With spamassassin you need about 20 to 30 seconds per email message and LOTS of RAM and CPU:
a) TRUE
b) FALSE
False for A - however, lots of ram and cpu is essential for any reasonably high throughput (this can be applied to many platforms). We process around 5 million incoming per day through the spamd layer, and each message takes around 0.5 seconds for spamd to process - this includes DNS (URI) checks, per-mailbox database lookups, local rulesets and DCC checks. The key is to have your resources local - if you're relying on external lookups to the Internet then everything becomes very variable...
