Postfix + Dovecot. Postfix не знает о Dovecot

Сабж. Действую по инструкции: http://en.gentoo-wiki.com/wiki/Mail_server_using_Postfix_and_Dovecot

Симптомы такие: логи в /var/log/mail* чисты, но по приходу сообщений Postfix их кладёт в ~/.maildir а не в /var/mail, как ожидает Dovecot.

Создал виртуального пользователя, которого не существует в системе (а следовательно и нет домашней папки) и Postfix вернул сообщение для него с объяснением ": unknown user: "andrey"".

Вот конфег:
