Hi Greg After beeting on this for three hours I have a solution but I don't like it to much. It's better then suid though. Use sudo with a line like this in your sudoers file greg ALL= (greg) NOPASSWD:/usr/bin/aplay then drop in your .mailfilter file `sudo -u greg aplay somefile` Like I said I don't like it that much but it does work and it doesn't allow anyone else to use aplay who isn't you. It also runs aplay as you. HTH --Frank
