I'm seeing a slightly different error:
This message was created automatically by mail delivery software.
A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed:
philipp...@redfish-solutions.com (generated from xyzzy@users.sourceforge.net) SMTP error from remote mail server after RCPT TO:philipp...@redfish-solutions.com: host mail.redfish-solutions.com [66.232.79.143]: 553 5.1.8 philipp...@redfish-solutions.com... Domain of sender address philipp...@redfish-solutions.com does not exist
This is on an externally generated email that is coming into my domain (redfish-solutions.com). The mailbox name is valid (it's been munged here to protect against spam address harvesters).
Looked at the cf/cf/generic-linux.cf briefly, but it's been too long since I've munged .cf files (these days I cop out and us the .mc versions instead).
What's going on, and how do I fix it?
Thanks,
-Philip
