Howdy,

Postfix uses the hostname for that, so you can either change your server's hostname, or set the hostname parameter in Postfix.

This is the real example, please check on both cases the rDNS

Your IP address 5.134.115.231 is associated with the domain first.smtp-sender.com. Nevertheless your message appears to be sent from ns1.smtp-sender.com.

You may want to change the host name of your server to first.smtp-sender.com.

Here are the tested values for this check:

IP: 5.134.115.231 HELO: ns1.smtp-sender.com

rDNS: first.smtp-sender.com

Here are the tested values for this check:

IP: 5.134.115.225 HELO: ns1.smtp-sender.com

rDNS: ns1.smtp-sender.com

Howdy,

Hmm, I'm not sure I understand your question... what is your server's hostname currently set to?
