hipwah.com mail is handled by 5 mail.hipwah.com.
[r...@mail postfix]# host mail.hipwah.com
mail.hipwah.com has address 202.134.118.114
I may be wrong, but I think I should not block sender on helo basis?

From my point of view it looks like reject_unknown_helo_hostname is far
to agressive, while reject_unknown_client_hostname and
reject_unknown_reverse_client_hostname would both permit this mail.
Correct me please if I'm wrong.
