TwitterHello,
I am having a problem where one of the domains I have on my server cannot send emails to certain addresses. These are @gmx.de, @web.de and aol.com. These providers give the following reason for the emails not being delivered
Emails from your email server were rejected because the PTR Resource Record (PTR-RR) of your IP address does not follow our guidelines. Possible reasons for this can be:
From the extensive research and reading I have done in this forum and the Google I kind of understand what is causing the problem but I can figure out how to setup it up correctly. My biggest problem actually is that there are 10-12 active email accounts for the problematic domain and I am afraid that if I don't setup everything correctly I might cause a bigger problem.
At the moment I have 2 domains on the same server and Ideally I want to setup up both correctly. From what I understand that might not be possible.
What do I need to do in order to have this fixed? Can I configure correctly the server for multiple domains?
Any help or pointers to the right direction or any articles that could help would be much appreciated.
Thanks

Emails from your email server were rejected because the PTR Resource Record (PTR-RR) of your IP address does not follow our guidelines. Possible reasons for this can be:
- The PTR-RR states that the IP address was dynamically allocated.
- The PTR-RR is a generic standard entry of your provider. Please allocate an independent and fully qualified domain name (Fully Qualified Domain Name - FQDN) to your email server and enter the corresponding valid PTR-RR.
- Individual rejection of the PTR-RR for system protection reasons. Please contact the administrator of your system who should then contact us.
