Has anyone heard of any problems dealing with Yahoo!'s 421 4.16.55?

If not, then we can probably expect the same with x.8.y, yes?
I haven't heard of any MTA that actually looks at ESCs, but that's just me.
StrongMail I know does and I think Message Systems does.
I'm interested in the SMTP conversation being the only conversation
that needs to take place about a given message. To the extent that
something like this proposal can get me to that goal, without driving
follow up questions from senders (e.g., "I got 554 5.8.5 unacceptable
content; what do I have to do to make my content acceptable?") then
I'm interested in seeing this move forward.
