Yeah, there's a huge risk of second-guessing; I think this
sort of thing is only appropriate for rare and
well-defined cases that occur at particular sites, rather
than for a general rule that should be forced on
everybody.
But if you wanted a to offer a useful hook for the odd
occasions where this is necessary, how about an optional
string expansion which is given the SMTP reply code and
string and context of the mail being sent, and expands to
either nothing meaning `treat the reply exactly as it says
on the tin', or to a new fake reply code and string which
exim will then use instead of the real one? Obviously it
should also log when such rewriting occurs....
