The number one reason for being able to receive email on a new second server is a smart host configured on the default SMTP virtual server. Make sure that you haven't got one set on there.
If there is, then replace it with an SMTP Connector.

Otherwise ensure that both servers can see each other, and telnet to each on the SMTP port:

telnet ip.ad.re.ss 25
telnet servername 25
telnet servername.domain.com 25

What does message tracking say? If you create a new account on the new server, what happens then?

Message tracking needs to be enabled.

If new accounts work correctly, then there is a possibility that the domain isn't updating correctly when you move accounts.

Thanks for your help anyway..... here is problem, the server had Microsoft POP3 service running aswell as Exchange POP3 Service which caused a conflict.  I removed the e-mail service from the server and now works fine.
