One possibility - did you specify the users home directory?

Output of dovecot -n would have answered this question ahead of time.

>From the wiki:

"Some uses for home directory are:

    * By default Sieve scripts are in user's home directory.
    * Duplicate mail check database is in user's home directory.
        Duplicate suppression won't work if home directory isn't



Best regards,
