Anyway asy70.asy179.tellcom.com.tr is a NXdomain. So maybe postfix
tries to look up the name it got from the PTR.
reject_unknown_reverse_client_hostname only checks that the PTR
lookups succeeds, it doesn't care about the lookup result like
reject_unknown_client_hostname does.
Sure? The error message
Jul 12 09:12:48 rap postfix/smtpd[6597]: NOQUEUE: reject: RCPT from
unknown[92.45.179.70]: 450 4.7.1 Client host rejected: cannot find

"cannot find your reverse hostname" sounds different to me.
And the documentation
http://www.postfix.org/postconf.5.html#reject_unknown_reverse_client_hostname
does not say that it does not care about the lookup result:
"reject_unknown_reverse_client_hostname
Reject the request when the client IP address has no address->name
mapping.
This is a weaker restriction than the
reject_unknown_client_hostname feature, which requires not only that the
address->name and name->address mappings exist, but also that the two
mappings reproduce the client IP address."
Hope this helps,
