Quick Sendmail access question

DARN! I know I forgot something.

I should have been more specific with the error messages.

When an Internet address attempts to send an email to a user in the new
configuration, they get a message of "Relaying denied. IP name lookup
failed [ip address here]". 

When an internal user attempts to send an email, it appears to work now.
(I have a feeling this was a mistake on my part, since rectified)
