What about shared mailboxes?

Close; but it still requires conversion for namespace (and hierarchy
separator ?) details that the MTA really shouldn't have to worry about.
At least not when using LMTP for final delivery.

I've been thinking about finding the cycles to whip out a utility
that would take a local_part on the command line; and return success
or failure to indicate whether it is deliverable. It would work by
starting an LMTP session and issuing a RCPT; then RSET and QUIT after
getting the response to the RCPT. Having to spawn a task to do that
is a bit ugly; but I don't think Exim has a way to do it internally.
(Or at least not directly. I might be able to do something with the
built-in perl lib...)
