I don't have any user boxes on my gateway. So should I make user_pref exactly the same as local.cf?
No, that's a waste. Make user_prefs an empty file and put all the settings in local.cf
Thanks I will merge the setting into local.cf. One thing user_pref disables DCC and Razor along with autolearn. Should I disable them in local.cf?
I have no users on the gateway. It will be amavis killing virus and SPAM. Do I need at least 1 user?
Erm. Yes.. you always need at least one user on your system. Can't boot without root.
You are absolutely right.
# ls -l /var/lib/amavis/.spamassassin/user_prefs
-rw-r----- 1 amavis amavis 772 Mar 15 11:38 /var/lib/amavis/.spamassassin/user_prefs
Should I feed SPAM/HAM to postmaster?
