ostfix Mail Server Manager
Rebuild your mail server with Amavisd, Spamassassin, ClamAV (AntiSpam and AntiVirus Protection)
Hostname needs to have a valid A record and rDNS/PTR set for successful email delivery.
**Reject the request when the hostname in the client HELO (EHLO) command has no DNS A or MX record. The unknown_hostname_reject_code specifies the response code to rejected requests (default: 450).

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

rDNS/PTR check for IP  = My ip not found!
rDNS/PTR check for IP  = My Ip not found!
rDNS/PTR check for IP  =MY ip  not found!

You need to set a hostname by creating an A record in your DNS to point to your VPS Public IP.For example server.example.com

For rdns, you need to speak to your IP provider to set that for you and must also resolve to the public IP of your server

The last point did not understand very well.
Do I have to talk to the company that gives me the ip?
I have to ask them to define rDNS what do I have to do on my machine?

Yep, you have to ask the server or IP provider

Hello

Yesterday I spoke with ISP it says that the ip is not pointing to the domain but I went where I have the registered domain and I have the minus pointing to i fixed IP
Does this happen because it does not have the cpwpro version?

You must have a domain which was registered (you must be owner the domain). And then you will be able to set the PTR.
