Just for the heck of it I added the above to my SpamAssassin setup at
home. However my syslog shows:rules: failed to run __F_DM1 test, skipping: (Can't locate object method "from_domains_mismatch" via package "Mail: [...]:SpamAssassin::PerMsgStatus" at (eval 1816) line 19.) I did restart SA after adding this.
