Well, there's one positive side to this thread Noel. Your reply to "undisclosed recipients" instead of the list address broke my postfix-users sort filter. I just spent 20 minutes trying to figure it out. I tried "received" and "return-path" and all kinds of header checks in the T-Bird message filter, and none of them work on this message. They clearly should.
So now I get to file a bug report on T-Bird as it's clearly not processing the headers correctly or obeying "custom" headers I plug in. Hell, it won't even filter on Sender: owner-postfix-us...@postfix.org for Pete's sake and Sender is built into the filter, not custom, IIRC. Regardless of the T-Bird issue, could we all please reply to the list address instead of burying it in a BCC? That's just plain silly. Thanks. -- Stan
