A client of mine is unable to send an email to someone in the Czech (across seas). I have included the Undeliverable Message, but for some background info: They are using Microsoft SBS 2003 which includes Exchange 2003. The mail is then going through our relay server which has Microsoft Server 2003 installed and Exchange 2003.
Here is the Bounce:
