But I, at least, am thinking in terms of an implementation where we
notify the SMTP-sending-server during the SMTP session, with a message
including a URL for more information. IMHO, this would tend to converge
to a situation where end-users understood the issue -- and learned to
route around it. ;^)
Where is the business of the main IETF mailing list in that suggestion?
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.
