[cobalt-users] SpamAssassin offloaded to another machine?

[Greg Hewitt-Long <cobaltusers@xxxxxxxxxxxxxxxxxxx>]

Has anyone off-loaded spamassassin to a secondary machine?

I have a server I'm trialling NuOnce's implementation of SpamAssassin 
(http://www.spamassassin.org) and I like the results - however, the server 
load is amazing (not so much the base product, but I have added 40,000 
lines of custom rules in the local.cf).  Each spamd grabs up to 78Mb of RAM 
- so I'm thinking of off-loading the tasks undertaken by SpamAssassin to a 
secondary machine whose ONLY task it to run spamassassin and razor - has 
anyone done this?

I'm thinking that I'll probably use or build a custom machine for this 
task, something cheap and cheerful, perhaps a colomachines.com box, perhaps 
a machine using AMD processors I have around - possibly building several 
machines using even lower specs and attempting to round-robin them if 
that's possible.

I'd be interested in the changes to the spamassassin config files here on 
the RAQs, and experiences of a choice of OS for the separate box - ie, 
linux/BSD etc.

thanks
