Activation email Feedback

[1]

Hi guys, 
new here, giving feedback on activation email delivery problem.
First registered with public mail service didn't get any not even to my spam folder. Then changed to own mail server to dig deeper. 
Now more technical stuff for the server admins:
The problem: Lied in pretty standard postfix sender restrctions - http://www.postfix.org/postconf.5.html#r...der_domain that rejected email with Domain not found 450 status 
The cause: The A, MX records seems legit, the problem might be caused in missing PTR.
