Hi,
Bit of a strange problem here. One of our users sent a mail out to his
friend (on an external host). He received a bounce back from
MAILER-DAEMON@ourdomain.com:
"Hi, this is the qmail-send program at ourdomain.com. I'm afraid I wasn't
able to deliver your message to the following addresses. This is a permanent
error; I've given up. Sorry it didn't work out."
There then followed a list of around 40 email addresses, none of which we
recognised. The addresses included users at aol, netscape, mindspring,
prodigy.net, etc.
After that was a copy of the original message - the message our user had
sent out to his friend. None of the headers of the message include any of
the 40 or so addresses which had bounced - ie they hadn't been cc'd in
I checked the qmail logs for the last 4 weeks, and saw no attempt by qmail
to send mail to any of these unknown addresses. As the bounce message also
contained the IPs of the remote SMTP server (eg "Giving up on
xxx.xxx.xxx.xxx"), I also grepped through the logs for these IPs ... again,
nothing.
I'm running Fedora Core 4 (x86), if that's relevant.
Any ideas what on earth could be causing this? It seems to happen
occassionally and at random
Thanks,
Pete
