reading message 1 of 2 (3113 octets) .fetchmail: SMTP error: 553 5.1.8 <jimc@xena.cft.ca.us>... Domain of sender address jimc@xena.cft.ca.us does not exist fetchmail: mail from FETCHMAIL-DAEMON@kleigh.nl bounced to jimc@xena.cft.ca.us
What is the point of bouncing a message to a domain you know does not exist?
It's risky sending a 5xx (i.e. "Go away and don't come back") error because the domain doesn't resolve; the nameserver could be down, network problems, etc. Normally this is treated this as a temporary error and send a 4xx instead which tell the sender to try again later. In any case, the manpage doesn't mention anything that would automatically delete double bounces but you can do that with procmail or whatever you filter your mail with. -- -ckm
