SMTP error from remote mail server after RCPT TO:<target email address>:

PTR record is present and looks as follows

If you created that in Directadmin it won't be seen as a valid PTR record because PTR records need to be set with the ip owner.

You need to set that PTR record where you cat the ip address from, mostly your datacenter.

i AM the ip owner / server owner and it's set through the admin level at the dns management section. The server is handling the DNS
