determing local path

[Duane L.]

Someone enlightened me of a very helpful qmail command that took a local
email address as an argument, and then it spat out the path to where it
would delivery the message... except I can't recall the command and I've
lost that email, and (of course) can't remember who sent it.

I'm having some difficulties trouble shooting a mail delivery problem for
one of our users, and I'm sure the output of this command (whatever it is)
would be most helpful.  If you happen to have a guess, please let me know.
