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, John
