Our product supports SpamAssassin and comes with the Windows version.
Sometimes in high-volume environments we want to recommend
SpamAssassin to run on its own box in Linux. In this configuration we
want to suggest a server hardware setup--including processor (type and
number), Ram, RAID array #, other.
Maybe I missed it, but I could not find a recommended server config on
the site. Does such a recommendation exist and/or does the user group
have a suggestion? This info is for a white paper we will publish on
our Web site.
For my high-volume MX hosts, I normally go with 6-8G of ram and use a
swap backed filesystem as inbound queue. This really improved virus
scanning speed, and viruses never hit the disk. About 30% of my inbound
traffic is some sort of spam/scan email that gets silently droped. For
the 6-8G of ram to make real sense, you'll need a 64bit OS. After
messages pass my battery of virus engines, it is moved to disk where
spamassassin processes and the rest of delivery happens.
There are risks of course, power outage would lose things in the queue.
I have a good power backup system in place to mitigate that risk.
