I have upgraded our exchange 5.5 server to 2000, now I have an issue with sending and recieving external emails.
Let me give you the layout. Have AD domain name of xyz.com Have Internet domain registered as xyz.com as well.
When users send users out or people send to people internally, the mail does not go. There are no errors.
The smtp virtual server queue does not show any mail queued up.
Now I have another internet domain name of xyz.biz. I added that to a users email addresses and made it the
default return address. Now users can send and receive emails. They can get emails either under the .biz address or the .com address as long as .biz is the default return address.
While this works, we have used .com all this time and do not want to switch to the .biz, it is only for emergency.
Does anyone know as to why and how this can corrected?
