Could be mx timeouts, DNS timeouts, rbl timeouts, dcc/razor/pyzor
timeouts...

In your global SpamAssassin config, try setting a value for timelog_path -
this will cause spamd to log what it's doing, and where it spent most time
doing it.  Check perldoc Mail::SpamAssassin::Conf.

You might also try turning on debugging (modify /usr/local/etc/rc.d/spamd.sh
so that spamd is called with the `-D' option, then restart spamd).  You will
then get lots of debugging in /var/log/mail.
