Greetings,
I have a user who gets a message delivery failure with the failure saying:
Delivery Failure Report
Your message:
XYZ
was not delivered to:
because:
73
I looked up what an error 73 is and it says:
-73 ERR_NO_PREDFINED_MX No Predefined mail exchanger
What does this exactly mean? Is this an issue on their end or mine?
Thanks
