Configuring the rDNS for a linux server is easy. A windows server with plesk is a different story.
Plesk
I changed the hostname in the plesk Tools and Settings.
Rebooted the system. Then sent a test email. Here is the header:
Received: from WIN-QO7M1M92HBS.home
Humm…where is the new hostname? So I did some investigation. I checked the computername in windows:
Then I checked the Mailenable settings > Services and Connectors > SMTP > properties.
So, the email received from name is a combination of the Windows computer name and the Mailenable Local domain name.
Now that I had this information, how do I give the mail server a valid hostname?
