I have a test server set up at mail.ans.co52.com running Postfix with a regex canonical recipient map:
/etc/postfix/recipient_canonical-regexp:
/[0-9]+@mail\.ans\.co52\.com/ catchall
I need to be able to forward messages sent to NNNN@mail.ans.co52.com to catchall@mail.ans.co52.com.
Sending email directly to catchall@mail.ans.co52.com works fine, but if I send mail to 4403@mail.ans.co52.com it fails with this log message:

What does "451 Temporary local problem" mean, and why would it work for messages sent directly to catchall@mail.ans.co52.com and not 4403@mail.ans.co52.com?
