And indeed:
% host mycrysis.com
mycrysis.com has address 62.67.9.135
80.237.209.12 is the client IP address, 62.67.9.135 is not.
Therefore, Postfix will not use the name..
By the way, their DNS is easily fixed:
mycrysis.com. IN A 62.67.9.135
mycrysis.com. IN MX 5 mailout.mycrysis.com.
mycrysis.com. IN MX 10 mail.mycrysis.com.
mailout.mycrysis.com. IN A 62.67.9.134
mail.mycrysis.com. IN A 80.237.209.12
134.9.67.62.in-addr.arpa domain IN PTR mycrysis.com.
12.209.237.80.in-addr.arpa IN PTR mycrysis.com.
The fix is to replace that last record by:
12.209.237.80.in-addr.arpa IN PTR mail.mycrysis.com.

Blocked by reject_unknown_client_hostname. If you don't want to
block this, don't use reject_unknown_client_hostname, or fix the
DNS for mycrysis.com.
