-
- First, there is no sensitivity in PMDF to <> on addresses. PMDF simply does not
- care if the angle brackets are present or not.
-
- Second, returning mail to the Sender: address is totally incorrect. It is a
- blatant violation of standards (see RFC1123 for details) and can cause major
- operational problems, including message loops.

-
- The way this is controlled is either by setting the envelope From: address
- (which appears as the Return-path:) or the nonstandard Errors-to: address. PMDF
- will honor Errors-To: if it is present; this is an extension to the standards
- which say the Return-path: should always be used for returning messages.
-
- Lists which don't set a proper Return-Path: can expect to have messages
- returned to whatever address is in the original Return-path: (usually the
- message originator).
-
- There is no option in PMDF to use the Sender: header for returns, and in view
- of the fact that this would amount to a massive violation of standards there
- never will be such an option.

-
- Set the notices timeout value to a huge value and return will never process
- messages on that particular channel. The exclude_list mechanism was never
- documented or supported.
