Hello Security Center->SMTP Restrictions and i see that it is disabled. What is the reason for this ? I have valid PTR, SPF or DKIM records

  Hello there! If the message isn't sending out at all, PTR/SPF/DKIM would not be related, since it's not leaving your server. I would recommend testing the outbound connection that mail will use with telnet. You can do that by running this command from your server: telnet mx1.cpanel.net 25
  Note - if telnet is not installed, you can run "yum install telnet" to get that package installed on your machine, as that is included with the base operating system packages. If that command times out, that would most likely indicate your hosting provider has blocked port 25 for your server, and you'd need to contact them directly to get that resolved.

  PTR/SPF/DKIM makes mail receiver able to verify the origination of emails, see how to configure it at Email Deliverability in WHM | cPanel & WHM Documentation Check that your SMTP server is running and setup correctly, see how at Exim Configuration Manager | cPanel & WHM Documentation Hope this helps!
