I am receiving the following error from some OE clients when the user tries
to send an email through our exchange server. I do have relay set to
authentication and OE is set to pass user name and password when it sends a
message. Message sent to address within the exchange domain name work fine.
What am I missing?
OE Send Error:
The message could not be sent because one of the recipients was rejected by
