  password_query = SELECT CONCAT( pw_name ,'@', pw_domain ) AS user, \
    pw_passwd AS password, \
    pw_dir as userdb_home, \
    89 AS userdb_uid, \
    89 AS userdb_gid \
    FROM vpopmail vp \
    LEFT JOIN aliasdomains ad ON ad.alias = '%d' \
    WHERE  ( vp.pw_domain = ad.domain  OR vp.pw_domain = '%d') AND ( vp.pw_name = '%n' )
