I'd suggest a separate draft, since this is a potentially complex
topic where it'll be a challenge to document existing practice, much
less decide who's right when practice diverges.

Straw man:

  220 server

  EHLO foo
  250 whatever

  MAIL FROM:<a>
  250 ok

  RCPT TO:<b>
  250 ok

  RCPT TO:<c>
  450 try later

  RCPT TO:<d>
  550 no such user

  DATA
  blah blah
  .
  554 ugh

  QUIT
  220 server

Which, if any, of b, c, and d get retried?  Why or why not?  What if
the 554 were a 450?

R's,
