How heavy is your load and how powerful is the machine?
| - Is it integrated with sendmail?
In what way? There is spamass-milter, but I've heard it doesn't
really work (deadlocks). SA can be integrated just like any other
unix-style filter program -- if you can send data out to a pipe and
read the result it back in then it is integrated.

I use sa-exim (a function to embed spamc inside exim and performing
scanning before accepting the mail) and run spamd on the same system
(because it's my only system and the load isn't too high).
Others (eg a large ISP) might have a farm of servers running spamd and
use some load-balancing techniques to choose which server scans the
next message. Some sites even have multiple MX servers using
round-robin DNS on the A records to try and load balance the system.
It all depends on your needs.
