I don't use the settings in user_prefs and prefer to set everything for our
domain in /etc/spamassassin/local.cf (SA 3 on Trustix 2.1)

My set up uses Postfix feeding SA directly. I don't have any truck with
milter-ing.

Here are my SA local.cf settings, for interest.

# These values can be overridden by editing ~/.spamassassin/user_prefs.cf

# IL 11/05/2004 We do not use user_prefs.cf at this point.

# These should be safe assumptions and allow for simple visual sifting
# without risking lost emails.
