Hello All,
I have researched this without a 100% clear reason that an exchange
server would return this error:
The error that the other server returned was: 550 550 #5.1.0 Address
rejected
My guess is it’s an invalid email address that we attempted to be
delivered to, but I want to be positive.
Exchange doesn't like your server or something about the message it
tried to send.
That's about as specific as you'll be able to get unless you can talk to
the Exchange admin and ask him/her what the problem is.
