We've just transferred a domain to GoDaddy and parked it. Then bought an email plan for it and got them working ok. Problem is we can receive most emails but whenever somebody from China emails us, the email bounces with "domain not recognized" or "unknown recipient" even though they are correct. I have double checked the mx records and they are correct. It has been 6 days since the mx update and it should have fully propagated before now.
We do a lot of business with China and the emails are vital. Does anyone have any clue as to why China cannot email us? Our domain is coriumsolutions.com.
