At this place (2,000 users), we currently have a couple of Solaris boxes that are running Exim and SpamAssassin and they seem to not be able to cope with the task.
they probably have the wrong approach, and/or is Solaris still called Slowaris?
The boxes are Sun servers with nice CPUs and memory. They run out of CPU resources (one or more SpamAssassin threads just hog the CPU and eventually bog down the servers).
yep, they got the wrong approach. Do envelope-rejection first, and then content-scan the only the rest.
And they're probably have the content-scanning using the POSIX regex rather than PCRE regex. There is a huge difference, like 30x, or 40x faster.
Also the guys in charge of these boxes are pretty bright too.
....hmmmm. Give them this sanity check:
An IMGate machine, "industrial grade" :)) :
Intel PII, 333 MHz, 256 MB, 1 ATA33 disk, FreeBSD.
The results for Thursday:
209864 received (bogus number, ignore) 21547 delivered 214689 rejected (90%) 40162 reject warnings
575m bytes received
682m bytes delivered
9730 senders
3632 sending hosts/domains

981 recipient hosts/domainssmtpd
214894 connections
24822 hosts/domains
8 avg. connect time (seconds)
459:20:31 total connect timeThe 22K msgs "delivered" are all content-scanned with PCRE.
Of the 6000 recipients, estimate about half are recipients of inbound mail, so the site is roughly the same size as your site.
Is that "industrious" enough for you?
