change IP scope and now emails will not come in.

[hdeassis]

I've change out IP schema to a different subnet. User can connect to our exchange server and send inner office emails and to the internet. However incoming emails are not arriving. I have changed the rules in our SONICWALL. Do I have to make any changes to our Exchange server? The exchange server has a new ip number and can browse the internet with now problems. Again sending emails is no problem it arrives on it's destination.


PLEASE HELP!!!

Have you changed the MX record in DNS?

I would check the NAT statement of the firewall and any rules regarding port 25 clearly have the new internal IP of the exchange server.
