Hi All

My first post on Anyway I have a bit of a curly situation which I need to solve ASAP. I have setup an exchange server on Small Business Server 2003 for a client of mine. They can only receive emails from certain people which is very strange.

If I email anyone there from my gmail account or hotmail account they receive the email fine. If I try to send one from my pop3 account or from my exchange account at my business I get an error message thrown back at me saying that it is an invalid email address. Anyone got any suggestions?

Does their isp provider have an MX record for their domain name in dns?

I believe so. Their isp used to host their email but i have moved them over to their exchange server. I have narrowed it down to their isp still has their dns records active. So anybody who has the same isp. In Australia the biggest isp is Bigpond. So anyone who is on bigpond can't email my client because their internet is primarily looking at bigpond dns servers which still has my client's old email dns records on it. Now i'm having the drama of getting through to Bigpond and getting them to delete the dns records off their server.

Does that make sense at all?
