Was contacted by a new client stating that they were getting the following error when trying to email an entity:

Diagnostic information for administrators:
 
Generating server: EXCHANGE2010.domain.local
 
initials@otherdomain.com
otherdomain.com #550 5.7.0 message refused ##
 
Original message headers:

The IT person for the receiving entity says it's because the Exchange server is on a .local domain and he had to put my client on a white list.  What can I do to alleviate this other than changing the internal domain name?

You do not need to change the domain name, use of .local is a very common way to set up Exchange.

You DO need to change the server name, as used in SMTP, or many other servers will choke on it.
