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.

Uhh, no.  He gave only the RFC 2821 SMTP Reply Code of 451, but not any RFC 1893 Enhanced Status Code ending in X.4.5.  More of the bounce might help.
