The main change you'll see in VMS MAIL in V4 is that you
don't need that stupid patch to make it leave case alone
in quotes.  Also, there is a new hook to allow you to attach
your own mail delivery mechanism to MAIL.  You can, for example,
send mail to an address of the form:

	arpa%"user@host"

Then, if you have a shareable image in SYS$LIBRARY called
ARPA_MAILSHR.EXE or pointed to by a logical name of the
form MAIL$PROTOCOL_ARPA, MAIL will activate your image on
the fly and map it into it's address space and call your
MAIL$PROTOCOL entry point.  There is a fairly simple calling
convention MAIL uses to give the message to your handler.

I'm in the middle of writing a handler for our UUCP system.
I will put it on the DECUS tape and maybe archive is somewhere
on a friendly ARPAnet site when it's done.  I have the outgoing
portion working, and am currently writing the code that allows
UUCP to hand a message to MAIL for local (or remote DECnet)
delivery.

ps.  No, the mail hook is not documented anywhere (as far as
     I know).  There are no useful comments on the fiche
	 either.
