mm/dd/yy hh:mm:ss NonExistent: rc
Explanation
The connection no longer exists for the specified return code reason.
The connection could have been dropped because of a software error
on the remote SMTP server or because of a routing or connectivity
problem in the internet network.

In the message text:
mm/dd/yy
The current date in the month/day/year format.
hh:mm:ss
The current time in the hours:minutes:seconds format.

System action
SMTP continues.

Operator response
No action is needed.

System programmer response
Normally, no action is necessary. The mail is delivered automatically
at a later time when connectivity is restored. If the error persists,
check for a software error in the remote SMTP server or for an error
in the piece of mail itself. For example, if a user tries to send
a binary piece of SMTP mail, some hosts’ SMTP servers malfunction
or abnormally close the connection.
