I don't recall it, but my memory isn't as good as it was.

It sends the error to postmaster only if the caller is trusted.
Otherwise it sends it to the caller.
I believe the idea was not to delay a whole batch of messages just
because of a problem with one of them. Not quite sure what you mean by
"missing are any other details". The code appears to be written so as to
include any envelope sender, recipients and header lines that it has
read before detecting the error.

Incompatible change. I don't like incompatible changes. Some
unsuspecting person always gets bitten.

This would have to be optional, because it is an incompatible change.
Note that an error code would mean that *some* of the input was not
successful. Earlier messages in the batch would have been sent.

I do not make any use of BSMTP; it was very much a bolted-on facility
for UUCP users who wanted to use it. What do other BSMTP users think of
this idea? I need additional opinions!
I will add it to the wish list, but I'm not extending Exim just at the
moment; I'm waiting for the 2.1x releases to settle down while trying to
consolidate documentation.
