to=msource-domain.com@domain.com [13], orig_to=msource@domain.com [14],
relay=none, delay=0.39, delays=0.23/0.14/0.02/0, dsn=5.4.6,
status=bounced (mail for domain.com loops back to myself)

It looks like there's a configuration issue somewhere. In the above example, is "domain.com" on your server, or another server?

It looks like the DNS settings for "domain.com" resolve to your server, but that your server isn't configured to receive email for that domain.
