I get rejects like this from time-to-time: The enclosed message, found in the XXXXXX-L mailbox and shown under the spool ID 1522352 in the system log, has been identified as a possible delivery error notice for the following reason: mail origin is listed in the "Filter=" list header keyword (or its default value for the XXXXXX-L list). What headers are examined? I've always assumed only the From: and Sender: However, I have some mail now that has this message and I can't see anything wrong and none of my filtered addresses are present. What else could trigger this message. The list is Send= Editor and the message is generated after the editor sends it back with the Resent- headers. -- When a clock is hungry it goes back four seconds.
