After some inspection and guessing, I suppose that they seperate their
mail clusters into 2 parts: receiving server and relaying servers. The
arch my looks like below:
Receiving:
@msa.hinet.net -> MX RR is msa0.hinet.net
Relaying:
msa.hinet.net are actually servers behind a load balance box or
something like that. Each incoming request will be redirected to
different servers (You could find that by issuing a HELO smtp command)
Well, I think they play these tricks without awareness of sendmail's
smart relay, which is "too smart."
This might explain why my emails and Edward's (if he's using
hinet.net, too) are rejected by ISP's smtp server.
Of course, since the problem is addressed, it could be solved. This is
another story...
