[NMLUG] Email service that does graylisting/razor/spamfiltering/etc?

[niosop at gmail.com (Matthew Bowie)]

Glad to hear I may have been of some indirect help  :)  Mind if I ask what
the machine specs are and what kind of daily volume you get?  Just wondering
because I'm looking at a mail server I set up for a client, and although
it's not a server class machine, it does OK on 512MB RAM, mostly by limiting
the maximum number of virus and spam checking daemons that run at one time
(it's typically CPU bound anyways, so more RAM wouldn't help much).  A
typical day's traffic is something like:

Total incoming SMTP connections: 16130
Total Blocked by Spamhaus: 1580
Total Blocked by Spamcop: 4570
Total Blocked by blacklist: 268
Total Blocked by SpamAssassin: 5122
Total messages delivered: 2784

Machine specs:  AMD 64 3500+ (running 32-bit Debian), 512MB of RAM.
Courier using RBLs+local blacklist+ClamAV+clamcour+spamassassin

The blacklist above is regenerated every hour with IPs that send more than a
set amount of spam identified by SA.
