$Home/Maildir qmail vpopmail

[Oliver - GoodnGo.COM]

Hello,

when I want to pop in my mailaccounts. My MUA delivered an error:  

'-ERR this user has no $HOME/Maildir'

What can I do?

How can I have to configure vpopmail, so that I can pop into my acccounts?

Is it better to use vpopmail al pop service? Or qmail-poop3d??
Please help me?
