We just changed our IP address and now when anyone tried to send us
email they get an NDR saying:

Remote host said: 550 Requested action not taken: mailbox unavailable

The only thing that has changed is the public IP address so I assume
that has something to do with it but I am not sure where to look for
the problem.

I tried to telnet to the exchange server and got the same message
after entering the body of the email.

I am not too experienced with Exchange so any help would be useful.

Thanks,

Scott
