It's so incredible that every time I get more information, there will
be more questions: now that I have everything setup for lahaya, I'm
messing with something that I can't get to work.

It used to be easy: my local account name in
/var/qmail/alias/.qmail-postmaster and every
postmaster@xxxxxxxxxxxxxxx gets delivered to me. Do I now have to
create a postmaster account for every virtual domain that I host?
