Luckily, most of spamassassin's CPU is spent in startup, so per-message
costs in daemon mode, although high, aren't anywhere near what they are
when you run spamassassin directly.  You can also put your spamd on a
different machine from your email server to separate the load.

You shouldn't have had to rebuild sendmail; some OSes don't ship a
libmilter with their sendmail, but FreeBSD does.
