Subject: No subject Date: Thu, 21 Oct 1993 23:05:29 -0400 | The example that the RFC cites is a special mailbox where errors are | to be sent could be used as the envelope address (e.g. the mailing | list administrator's address). That's exactly what we do. | I think that your sysadmins are right: the UA should reply to the From: | address stored within the message. I think that RFC821 specifies other | headers that can be used, too, such as Reply-To:. RFC 822 says that. See sections 4.3.1 and 4.4.4.
