Hi Guy's my company is in the process of merging, which means new smtp (pjack@some.com from pjack@somewhere.com). I just wanted to know is there a way of seting up a rule on the exchange that notifies all email senders that send emails to ?@some.com that the domain name/email address has changed to ?@somewhere.com. We have both smtp address in the domain wich is going to run for a few months and then we are going to remove it.
