Recently, I am getting emails bounced back to me from my mail gateway. Strangely, the attempted outgoing From: is FETCHMAIL-DAEMON@bragi.private.network ?!?! The entire bounce is here: <http://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@bragi.private.network 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@bragi.private.network: 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@bragi.private.network? [4] Is exim the culprit? Need I configure it differently? # sudo exim -bV Exim version 3.36 #1 built 24-Jul-2003 23:00:48 Copyright (c) University of Cambridge 2002 What do you think? -- Best Regards, mds mds resource 877.596.8237 - Dare to fix things before they break . . . - Our capacity for understanding is inversely proportional to how much we think we know.
