550 mailbox unavailable

Hi experts
I'm switching from a hosted email solution to hostine my own email on Exchange running on an SBS 2003 r2 box. When I telnet the server and try to send mail, I receive a 550 error, requested action not taken mailbox unavailable. This happens when I use the address "anyuser@mydomain.com". If I use an address "anyuser@mydomain.local" the mail goes right through. Checking the eMail addresses tab in user managment show "anyuser@mydomain.com" as the default SMTP address.   I can also get delivery when I send to "anyuser".  Additional, ".mydomain.com" is listed as the qualified domain name in Exchange config. Any help would me greatly appreciated. Thanks. Sharquet

Can you receive email normally to the fully qualified domain, without any telnet use?

I haven't updated the mx records to point to the exchange server as yet so the pop3 connector is still retreiving my mail from the ISP's, so I can't check normal delivery using the fully qualified domain. I did, however make my exchange server the outgoing mail served on a machine outside the domain and tried to send using the fully qualified domain and received the same error. I did run the wizard on set up and entered .mydomain.com as the fully qualified domain. Thanks experts.
