relay=smtp.ntlworld.com. [62.253.162.40], dsn=4.0.0, stat=Deferred: 452 Filesystem error - message not accepted

I'm guessing that's bad, espically as NTL's service status checker denies all knowledge of an outgoing problem.

Ho hum.

Maybe one day work will unfuck their mail server so it will relay for people inside the company, and I won't have to send all my outgoing email via an SSH tunnel to our server.
