Thanks or the reply. That sucks. Is there a way around this,
short of turning that off or whitelisting?
Tell the admin of the remote domain to fix their PTR records and/or MX
helo configuration because in the meantime, you're going to have to
implement a dirty hack to make their server work.
But the PTR needs no "fix".
The IP resolves to a hostname perfectly fine , only that the hostname
does not resolve.
Is that a valid reason to reject mails ?
I had to remove the reject_unknown_client because of this.
I hope postfix would have a *reject_no_ptr* .. that just checks for PTR
record exists.
From Postfix 2.3 on you can use reject_unknown_reverse_client_hostname:
