Well, the director in question will have some test of validity for
the truncated localpart. When there are several possible ways to
truncate, and only one gives a hit, "correct" is pretty clear, if not
always practical.
OTOH, it's actually simpler than that. We already have several ways
to truncate, in a case like userid-ext-ext2 and a -* pattern. In this
case, the spec says to use the longest sequence; so using the longest
match would be an obvious choice, and, in fact, that was exactly what
I expected exim to do. Even more, I still think anything different
must be considered a bug.
And, having done "take the longest match from a list" code myself,
it's also pretty easy to do. Hmm. Would you accept a patch that made
exim do so?
