Not necessarily.  It depends on the client timeout, which is beyond
your control.

Clamd has problems on Solaris, I believe.  And it also has a huge number
of signatures now.  We find Clamd to be very CPU-intensive.

Wow!  For CAD $600, you can get an AMD64 box at a couple of Ghz with

Apparently not. :-(  Clamd is hungry...  You really don't want to run
a production MIMEDefang setup on such an underpowered machine.
