Hi,
I had the same problem after an update and I just realized that I had a password error in the authentication with our exchange server.
the behavior was the same. I received emails inside our domain but mails to the outside haven't been send.
But I received an error message in "Application | Log viewer" tab.
It looks like if the password is wrong the mails are send anonymously? And it looks like it is possible in the own domain.
try to check your "application configuration" below "admin".
Have you checked the checkbox "enable authentication" and are your credentials 100 % correct?
