I've always have this problem, with sendmail, exim, and now postfix. There's something I must be doing wrong but really don't know what.
I have a LAN smtp server and wenever I send an email to an invalid address that the smtp server can't send to, I'm suppost to get a bounce, but don't get it, instead the bounce just bounces back and it creates an exponential mail loop which ends up killing the server.
Here's the log:
May 19 22:11:21 localhost postfix/smtp[410]: 89E85EC1BD: to=<fjdsklfjklds@invaliddomain.com>, relay=mail.invaliddomain.com[64.62.231.136], delay=7, status=bounced (host mail.invaliddomain.com[64.62.231.136] said: 550 5.1.1 <fjdsklfjklds@invaliddomain.com>...

May 19 22:11:24 localhost postfix/qmgr[10276]: 1BE65EC1BF: removed
Oh and the way it works is that the accounts I send with are local, but are set to reply to the external ones. So the bounce should be going to the external one, but for some reason it does not go anywhere.
