From the WishList section "things that didn't make it into Exim 4":
. Allow :fail: to specify that 551 be used instead of 550. Maybe allow a
code at the start, optionally? What about :defer:?
That isn't an ACL, of course. However, "deny" implies 5xx, so you
shouldn't be able to specify the first digit.
Are you seriously expecting any/some/many/all SMTP clients to actually
differentiate between 550 and 551? Even RFC 2821 admits that it is a
lost cause:
But, if a 551 code is used, they [servers] MUST NOT assume that
the client will actually update address information or even return
that information to the user.

Hmm. I thought it was a buried item like RFC1892, which has been there
for over 5 years, but I can't find it either. Not many people have been
calling for it.
