    The available  mail file formats for a host are determined
    by the return value of the (flavors) generic function
    ZWEI:NATIVE-MAIL-FILE-FORMATS.  The flavor that this
    needs to live on is called FS:UNIX-MAILBOX-PATHNAME-MIXIN.
    It returns a list of mail buffer flavors.  In addition to
    the list it presently returns (which is constant), it needs
    to return ZWEI:RMAIL-BUFFER.

This will cause it to use ITS EMACS RMAIL format, which I don't think is
the same as GNU Emacs RMAIL format.
