Your domain has two MX records (office. and mail.) and your server is advertising itself as mortgage-atlanta.com.

You are not configured properly (extract from domain report):

office.mortgage-atlanta.com claims to be host mortgage-atlanta.com [but that host is at 69.89.31.245 (may be cached), not 173.160.95.113].

Your primary MX record points to office.mortgage-atlanta.com but your server is not configured as office.mortgage-atlanta.com.

If you open up Exchange System Manager and locate your SMTP Virtual Server, right-click it and choose properties, click on the delivery tab, then the Advanced button, change the FQDN to office.mortgage-atlanta.com and then click OK several times.

You also need to call the ISP for IP 173.160.95.113 and ask them to setup Reverse DNS on that IP as office.mortgage-atlanta.com
