Check the Excahange services on the servers, see this list to see what they do;

Check if port 25 is open and available, run Netstat -a | grep "LISTEN". Also check using 'Telnet servername 25' to see if you get the SMTP banner showing.

Check that other programs or services such as Firewall, Antivirus or Antispam products have blocked the smtp port.
