It would be, but only in the case where there is one remote host. If
there are several remote hosts, Exim will try them all when temporary
errors are happening. Maybe the first one fails to connect, and the
second one gives a temporary error.

I think in this case, letting C keep the message is perhaps the safest
course.

I'll think about it, but I have a gut feeling that there isn't a nice
clean non-confusing way one can specify this. Consequently, I'd rather
keep clear...
