So, basically, the local postmaster user has an alias to [EMAIL PROTECTED] However, when bounces try to go to that user, the are being addressed from <[EMAIL PROTECTED]> and my Exim-MTA interprets that as a domain literal and disallows the message.
So use cancelmsg on the bounce itself, and it will go away.
I look forward to any replies that can help define why bounce messages destined for the local postmaster get sent as <[EMAIL PROTECTED]> when postmaster has been aliased to an offsite user. Thanks in advance.
<[EMAIL PROTECTED]> is not a bounce, it's a double-bounce. An attempt to send the bounce to the sender bounced. <[EMAIL PROTECTED]> is specifically chosen so that it CANNOT BE sent to a remote address. All double-bounces MUST be delivered to a local mailbox, in order to prevent nasty mail loops.
