If you run your own mail server, then this is the error message you get from 
your own mail server, so only you can fix it.

If your mail server is configured to smarthost all outgoing mail through 
your Internet provider's mail server, then this may be an error message from 
your provider's mail server. You only posted the error message, and did not 
include the rest of the non-delivery report, which would identify which mail 
server is reporting this non-delivery.

Anyway, since you did not include the complete non-delivery report, key 
pieces of information are missing that are needed in order to fully analyze 
this problem.
