        If you have compiled sendmail with DBM support instead  of  NEWDB,  you
        may  have  encountered problems in dbm(3) restricting a single alias to
        about 1000 bytes  of  information.   You  can  get  longer  aliases  by
        ``chaining'';  that is, make the last name in the alias be a dummy name
        which is a continuation alias.
