Resolved Different PTR type and hostname

[XCore]

I'm trying to keep as clean and compliant a mail server as possible. One of the things I've done is use a dedicated IP for all mail which is different from the IP I'm using for the control panel. However, I'm getting the following message when I test for issues. Any ideas on what I can change/add to comply?

Reverse DNS lookup or reverse DNS resolution (rDNS) is the determination of a domain name that is associated with a given IP address.
Some companies such as AOL will reject any message sent from a server without rDNS, so you must ensure that you have one.
You cannot associate more than one domain name with a single IP address.

Your IP address 192.xxx.xx.xx is associated with the domain mail.myservers.com.
Nevertheless your message appears to be sent from cp.myservers.com.

You may want to change your pointer (PTR type) DNS record and the host name of your server to the same value.
Here are the tested values for this check:

• IP: 192.xxx.xx.xx
• HELO: cp.myservers.com
• rDNS: mail.myservers.com

Any help is greatly appreciated.

Hi XCore,
you don't mention which MTA you use, Postfix or Qmail.
If postfix you need to change...

/etc/postfix/main.cf
myhostname = mail.myservers.com

QMail
/var/qmail/controls/me

Thanks, Lloyd.

The postfix edit seems to have done the trick.
