|
Answer» An SMTP reply is an ACKNOWLEDGMENT (positive or NEGATIVE) sent from receiver to sender via the TRANSMISSION channel in response to a command. The general form of a reply is a numeric completion code (indicating failure or success) USUALLY followed by a text string. The codes are for use by PROGRAMS and the text is usually intended for human users. Recent work has specified further structuring of the reply strings, including the use of supplemental and more specific completion codes.
