[Dovecot] dovecot & vpopmail

Hi!

Authentication works, but

default_mail_env = maildir:/usr/local/vpopmail/domains/%d/%n/Maildir/

is translated by the "imap"-process to

/usr/local/vpopmail/domains//testerhorst/Maildir/

although I succesfully log in as testerhorst@elektropost.org.

Is there a manual how to use dovecot with vpopmail?

We have here: FreeBSD 4.9-STABLE, vpopmail-5.4.0 and dovecot-0.99.10.4_2.

Thank you for your help!

Regards, Dirk Jaeckel
