	I have been altering the CF files, and at some point the
	LOCALNAMES file altered drastically.  Essentially I wanted
	to have multiple canonized names (canonized in local sense)
	which would not become mapped to the one and only name in
	the  /etc/mail.conf ..


	The  INSTALL doc says:

	----------------------------------------------------------------
        With the sample config files for mea's Zmailer-2.98, and latter
        this "localnames" is actually a mapping of those various names to
        the desired forms of the canonic name, thus an example:

        astro.utu.fi            astro.utu.fi
        oj287                   astro.utu.fi
        oj287.astro.utu.fi      oj287.astro.utu.fi
        oj287.utu.fi            astro.utu.fi
        sirius                  sirius.utu.fi
        sirius.astro.utu.fi     sirius.utu.fi
        sirius.utu.fi           sirius.utu.fi
	----------------------------------------------------------------

	But nobody reads that file when upgrading, right ?
	(I should have known..)

	Yes, but its use is different.  I wonder how I could make
	that change well known ?  Write a note about it to the
	list perhaps ?

	Naeh, I have been creating a "README.UPGRADING" recently
	(since  2.99.3, I think), it is better place to put these
	warnings in :-)

	Eee ....  491 names  ??
	(You must map even every PC, as valid local name...)

	I have some 20, and I use "ordered" -type, which means
	sort(1) order for the file.
