I jsut got this message on my mail server from one of my users. I'm not sure about it and I can only find two hits on google, and they are in french. 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. Thanks. -- -=/>Thom
