Hi, sorry to bother you guys and i am pretty sure that this has been asked before but since i didnt know what to search for here on forums i had to ask... If you can help me or at least push me to the right direction i would be really happy... I am not going to hide any domain names or ip address below here so i hope that is alright...
General info about server;
I have a Centos 7 x64 server with Plesk 12.5 that has 8 shared ip addresses... Primary domain is domain1.com which is hosted at ip1 and server hostname is ns.domain1.com, also all ip addresses have rdns defined to ns.domain1.com, "Send from domain IP addresses and use domain names in SMTP greeting" is selected at "Mail Server Settings", i dont know if it is related but this domain is using office365 mail service so it doesnt use plesk mail services...
My question begins here;
On ip2 ip address there is another domain domain2.com , when i test this domain on mxtoolbox and mail-tester i am getting below errors
- Reverse DNS does not contain the hostname
- Delivered to internal network by a host with no rDNS
Below are some reports that i gathered;
Mail-tester report -> https://www.mail-tester.com/web-AvTPPK
Port25 report
Can you please tell me what i am missing, what is wrong with my configuration and how i can fix it...
I dont know if you guys need master.cf or main.cf so i am sending all just to be sure...
