Message Not Delivered: email routing issue due to network

The message could not be delivered because network problems with the recipient's email provider limit routing this message.

Fixes

Try waiting a bit since the receiving mail server is busy. Also, double check the recipient's email address when sending again..

If this error continues, consider contacting the recipient through an alternative email address or other means.

5.4.4: Official Definition

5.X.X

A permanent failure is one which is not likely to be resolved by resending the message in the current form. Some change to the message or the destination must be made for successful delivery.

X.X.X

The mail system was unable to determine the next hop for the message because the necessary routing information was unavailable from the directory server. This is useful for both permanent and persistent transient errors. A DNS lookup returning only an SOA (Start of Administration) record for a domain name is one example of the unable to route error.
