After some thought, I agree.  This is a change from RFC 821, in
particular the "Too Many Recipients Scenario" in Appendix F (also in
smtpupd-01).

A sender-SMTP that correctly interprets a 552 response to a RCPT command
(I suspect these are a minority) must violate the "SHOULD test only the
first digit" clause in 1123, =A7 5.2.10.
