Thank You Larry,
I edited the /etc/hosts file and restarted sendmail and all is well now.

The SMTP banner has nothing to do with DNS, it is the local
name the server has for that IP address based on the /etc/hosts
file.  Check that file and make sure each IP on the box has the
correct name in the /etc/hosts file, restart sendmail and then
check (telnet <ip> 25) and the box should helo with the name
you put in the hosts file for that IP address.
