MVP's Messenger service is using _mvpServer in the originating EHLO (HELO) command header when negotiating a handshake with the SMTP server. Messenger appears to be using the SMTP server hostname (_mvpServer) instead of MVP's server hostname.
The MVP messenger command header values used during the initial handshake with the SMTP server should look like this: EHLO <Hostname*> <FQDN**>
(i.e. EHLO Moi.dhcp.lexmark.com)
* computer name for MVP server (Moi)
** fully qualified domain name for the computer running MVP server (dhcp.lexmark.com)
The plug-in MessengerHelo v 1.2 changes the MVP behavior to obtain the line: EHLO
