I have a client running a Small Busienss Server 2003 using the POP3 connector to download emails. All has been working ok until last Friday. The client wanted their primary email address domain changed, so under each user i created a new smtp email address and set the new address as the primary address. All looked ok - emails sent showed the users email address as the new ones but after a little while we realised that no one was receiving emails.
At first i thought it might have been an issue with the new domain name and DNS settings on the internet but after a couple of hours of testing i realised that emails were getting to their internet mail server (hosted by the company who looks after their domain names) but when the POP connector was downloading emails it was not sending them to the users exchange account - they were just disappearing.
After much panic and testing i have changed their primary email address on their accounts back to the original email address and now the POP connector is delivering emails correctly.
So i now have 3 questions:
1. The emails downloaded but not delivered -where do they go and can i get them back?
2. why would changing the primary email address cause emails to not be delivered?
3. how do i change the primary address and not have this problem come back?
With out giving the real domains the structure of the changes were basically:
original domain: smithxyz.co.nz
server domain: smithxyz.local
new domain: smith-xyzq.co.nz
No change was made to the server domain.
