Notes

3.2.2 is BROKEN, http://issues.apache.org/SpamAssassin/show_bug.cgi?id=5574 isn't entirely correct, but the idea is:

POSIX::setuid($uuid);  # set effective and real UID

SpamAssassin and userprefs on MySQL

Useful when using shared bayesdb and squirrelmail sasql. Read /usr/share/doc/spamassassin/sql.

mysql -u root -p
mysql>grant insert,select,delete,update on sasql.* to 'sasqluser'@'localhost' identified by 'sasqlpass';
mysql>flush privileges;
mysql>create database sasql;
mysql>quit

mysql sasql -u root -p < /usr/share/doc/spamassassin/sql/userpref_mysql.sql

and make sure to run spamd with the options -q -x.

On debian you set those in /etc/default/spamassassin under "OPTIONS".
