It is already a de facto standard. Many and probably most well run SMTP servers include an appropriate message in their 5yz rejection messages when spam detection is the issue. Today an appropriate message is often a URL. There are details that could be officially standardized such as formats that MUAs could more easily recognize and present to end users. The bounces generated by the near-end MTA after a failed SMTP session are incomprehensible to many people. Some MTAs (e.g. Hotmail's when I last checked) include random text in their session transcripts apparently drawn from random SMTP sessions during that last several hours. However, this sort of standardization seems more appropriate for some SMTP WG or the ASRG than here. Vernon Schryver vjs@xxxxxxxxxxxx
