Re: SMTP traffic control

Perhaps I missed something (this has been a long thread), but I'm completely 
missing how this will solve the problem of long, unpredictable delays for 
users. Everything I've read says these are return codes for server consumption, 
not to be returned to users. 

As best I can tell this proposed idea does nothing for the end user.

Hector, I've seen nothing in the past two of weeks of discussion that

It may not be a problem for you. For some (many?) users long and
unpredictable delays in mail delivery are a problem, especially if the
mail is sent during a phone call.

Such delays can be reduced and regularized if the server can provide
information about when to retry (and possibly other info, like the
number of allowed concurrent connections) to the client.

I really don't understand the resistance against the idea. Some servers
and some clients will implement it and benefit from it (if they are
talking to each other), others won't and for them everything will be as
before. How would a standardized way of conveying the same information
that some servers already convey informally hurt the mail system?
