Qmail -ERR this users has no $HOME/Maildir

[New Hope Hostmaster]

I've finally got the checkpasswd authorization to work, but not it's not
finding the $Home/Maildir.

I have put a Maildir in all the placing I think it may look, using the
qmail-makedir whatever command, but still no luck.

So, how do I change/find out the value of $HOME, so I can change it, or make
the necessary directories?

Thanks,

Peter Janett
