error messages on the list...

[Greg Stark]

The reason error messages appear on the list is because you've set the
Reply-To header to point to the list. This is flatly incorrect. It fixes a
minor problem that som people's MUAs don't respect the Mail-To: never header,
but causes lots of problems. The Reply-To header is supposed to be for the
author to provide an e-mail address to use in preference to the From header.
