In maildrop Make test for the user dir before process anything else. If the
directory of that user doesn't exist than call a little perl prg.

In the perl prg grep the domain .qmail file and check that there is a
delivery to somewhere. (so catch all is exists or not) In my system if a
user doesn't exists than it is bounced back to the sending server, so if I
can't find a user Maildir than catch-all is enabled. (I don't remember the
name of that qmail patch witch do this for me...)

If there it is, then find out this new users dir, and send back this info to

Than process evrything as usual.
Use vuserinfo and vdominfo.
