451-The server has reached its limit for processing requests from your host
Anyone know what this means? The details of the email are that there
is a user on vacation, and she is forwarding her email to her personal
email address, and this is what we are getting back.
The basic smtp message is a hard reject and means:
451
Requested action aborted: local error in processing
...for whatever reason. The server appears to only allow so
many connections from a single host. Probably and
anti-spam/anti-relay setting.
From RFC1893 on Enhanced Mail System Status Codes
X.4.5
Mail system congestion
The mail system was unable to deliver the message because
the mail system was congested. This is useful only as a
persistent transient error.

What MTA are you using on the server? Did you check the
queue??
