I'm really not any exchange- or sendmail-expert, but the domains
"hkusa.com" and "hkrt.hkusa.com" are different.
The former exists and has an MX-record, the later does not.
Some mailservers (including my very own) reject mails where the sender
has a clearly non-existing email-address (helo spam).

Perhaps you should create a MX entry for hkrt.hkusa.com and point it to
the same server as the MX for hkusa.com, using whatever techniques
MSFT-exchange provides to sort-out the mails....
Whatever MX you configure for hkrt, it should ideally also provide the
outgoing mail, as some servers reject mail that is not sent from the
MX...
