Title: (ERROR: You don't have a valid hostname set!)
Post by: joekirk on April 01, 2018, 10:34:17 PM

Your Hostname is: localhost.localdomain and it resolves to IP: (ERROR: You don't have a valid hostname set!)
 rDNS/PTR = FAILED, check with your hosting provider! FAILED

rDNS/PTR check for IP addr:192.227.206.26 = not found!

BUT.........

Current Settings in Postfix:
 

mydomain = myhostname.org (NOT REAL HOSTNAME) myhostname = node.myhostname.org (NOT REAL HOSTNAME)

And from the main page:
[/b]

[/pre]

• Server IP: ***.***.***.** | node.myhostname.org
•   Shared IP: ***.***.***.*** [Change] (https://node.joekirk.org:2031/admin/index.php?module=settings)
•   Hostname: node.myhostname.org [Change] (https://node.joekirk.org:2031/admin/index.php?module=change_hostname)

• Server IP: ***.***.***.*** | node.myhostname.org
•   Shared IP: ***.***.***.*** [Change] (https://node.joekirk.org:2031/admin/index.php?module=settings)
•   Hostname: node.myhostname.org [Change]
   (https://node.joekirk.org:2031/admin/index.php?module=change_hostname)

 My server provider has already changed my rDNS, I should not be getting that error.

simply from cwp change hostname to match your rdns.
If this is a vps maybe you will also need to do an update of the hostname from vps panel
