I have a reseller account on a web host. I would like to implement some custom rules for SpamAssassin. I've read the SA docs and written the rules. If I place them in the file ~/.spamassassin/user_prefs the rules are ignored as set by the system admin for security reasions. Where could the sysadmin for the web host place the rules for me so they would only affect the mail processed by SA for my domains? He is willing to custom place them for me after checking them to be sure they aren't security risks but he isn't sure where to put them. Ideas?
