That's a necessity - a caching-only server is fine

Good

Yes

* use spamd to save memory

* AV first
You mentioned you scan for viruses - do you do that before or after scanning for spam?
If you scan after, move it to before.  Use clamav-milter on the same box and save an expensive MIMEDefang thread.  (Make sure the milter order puts clamav-milter first.)

* /tmp swap too
SpamAssassin uses /tmp as a helper directory for all of its plugins.  Make sure that's also a RAM disk (I believe that's the default for Solaris anyway?)
