Yeah, this is strange. Postfix is such a successful package that everthing
is solved within a very short period. But this problem has been floating
arroung for quite some time. Also, I noticed that quite a number of the
problematic hosts are from China. And yes, my problematic server is hosted
in China too.

No, no patches. Strictly installed from an rpm.

No, I don't.

The problematic host, chinamail, is placed behind a firewall (pfsense-a
great router). There is not nat for port 25, since this mail will not
recieved email from the net. It only send and receive email locally, and
send-only mails to the internet.
