The text after the message is not used by the MTA - it is solely for
human interpretation. Unfortunately, there is no code to do what you
want. The only standard recognized conventions for the numeric
responses, and their meanings, are as follows. What numbers are in the
'x' dont matter.
2xx Success
3xx Success, send more (used after "DATA" command)
4xx Temporary failure
5xx Permanent failure
