fix Dovecot's home directory

Browse Source 
Dovecot's home directory is a user-specific state
directory, see https://doc.dovecot.org/2.3/configuration_manual/home_directories_for_virtual_users/.
It is recommendated
1. to never configure a userdb to return the same
   home directory for multiple users
2. to store the mailbox under the home directory,
   e.g. home = /var/vmail/domain/user and
   mail = /var/vmail/domain/user/mail
This change implements these recommendations. For
stateVersion 24.11 or later, the mailboxes are
stored at ${cfg.mailDirectory}/<domain>/<user>/mail.
Existing mailboxes are moved automatically to the
new location by the systemd service
dovecot-move-maildirs).
