| This is really strange because 5.1.1 has nothing to do with relaying, it
corresponds to the recipient that does not exist at the org the mail was
sent to. The CAT can also issue this NDR when it encounters illegal chars
in addr821.
Try to telnet to the server in question and submit mail manually. If it
fails the problem is on their end (what I tend to think).
Strange indeed.
