I have a LAN that has an Exchange 2010 server and a Linux Postfix server
Trying to send a message from an account that is on the Exchange server to an account
that is on the Linux server I get the following error:
Diagnostic information for administrators:
Generating server: Server1.Domain.local
#550 5.1.1 RESOLVER.ADR.RecipNotFound; not found ##

I am able to successfully send messages to other accounts that are on the Exchange server.
I am able to send mail to the Linux accounts from outside the LAN no problem.
Thank you for your time,
