I don't get it, I don't understand what you meant.

I followed what Magnus said to do these following steps, I think you may not
read his post.

dogs.cnexample.com

In this case, we found the one of ISP can help us to relay it to send out
emails to China, Hong Kong and so on. He just give us one email account to
relay. Therefore we need to forward some domains belonged to China NIC, Hong
Kong NIc and so on to this ISP, so that we can send out the email to China,
HK domains.

NO, relay the relative mails to the specific email address.

Yes, I know this. thank you for your reminding.
