Recently, I am getting emails bounced back to me from my mail gateway.
Strangely, the attempted outgoing From: is
FETCHMAIL-DAEMON@??? ?!?!
The entire bounce is here:
<
http://www.helices.org/tmP/exim.relay.txt>
I do not claim to know much about this process.
However, correct me if I'm wrong, it looks to me that -- initially --
fetchmail gets an email message from one of my many remote mail servers,
and passes it off to exim for local processing.
The To: header is mangled, and noted, and 550 is returned.
Then, somehow -- this is the part that I do not understand, and that I
want to *STOP* happening -- FETCHMAIL-DAEMON@???
attempts to send an email -- containing this 550 error -- to some
address unknown to me. Note: the URL is only one (1) of many
_different_ examples I am seeing.
Of course, the remote SMTP server rejects
FETCHMAIL-DAEMON@???: Domain not found, and
eventually, I receive the error that the bounce bounced!
So, I want to know several things:
[1] Am I correct on the process as evident from the URL?
[2] What process steps am I missing and/or misunderstanding?
[3] How can I prevent these attempts to send these messages From:
FETCHMAIL-DAEMON@????
[4] Is exim the culprit? Need I configure it differently?

Our capacity for understanding is inversely proportional to how much
we think we know. The more I know, the more I know I don't know . . .
