Gentlemen, the TRAC bug tracker is not as smart as bugzilla. It insists on sending one acknowledgements even for one's own actions.
It was me doing the clicking, no acknowledgement needed. But if it was someone else changing/commenting on one of my bugs, well yes, I want mail about it. So to get mail on others' actions on our bugs, but not our own actions, we must make fancy SpamAssassin rules: header __J_TRAC_COMMENT X-Trac-Ticket-URL =~/\#comment/ rawbody __J_TRAC_MY_COMMENT /\+-+\nChanges \(by jidanni\):\n/ meta J_TRAC_OTHERS __J_TRAC_COMMENT && !__J_TRAC_MY_COMMENT score J_TRAC_OTHERS -7 Fortunately TRAC breaks other rules, like missing To: headers, so the above is all I need, at least for the WordPress TRAC.
