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.
