I recently redirected our email to a new IP address. Previously, the OWA URL and the SMTP traffic were pointed to the same IP address. Now the IP addresses are pointing to different IPs. Will this provide a challenge for mail delivery? Reason I ask the question. I am getting a lot of delivery is delayed messages from sending email servers and I am wondering if this might be the culprit.

There's nothing that requires them to be the same IP address.Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."
