Make sure the correct FQDN is sent in the HELO\EHLO command. The name should match the DNS "A" record with the IP address seen by the receiving server. --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP

ESM, Servers, <your server>, Protocols, SMTP. Right click on the default SMTP VS and choose Properties. Click on the tab Delivery, and then Advanced. In the FQDN change the field to match the A record that is on the external DNS record for the server. Ideally it should also match the PTR (aka reverse DNS) on the IP address as well. Apply/OK out.
