This is a sample foreign mail protocol that hooks to VMS MAIL to
allow VMS MAIL user's to send mail to foreign mail delivery systems.
This is NOT intended to be directly usable by anyone unless they
have our UUCP distribution (in which case they already got this).

This should, however, provide a model on which to build your own
foreign mail interface.  I regret that I haven't documented things
terribly well here, but a LOT of work went into decoding MAIL code
listings to figure this out and I didn't have much time in all that
to write everything down.  Hopefully, if anyone REALLY wants to use this
they can follow the code.

By the way, the file with the extension .PAS_DEBUG_OFF and .OBJ_DEBUG_OFF
are copies of the UUCP_MAIL code with the DEBUG flag disabled.   This is for
any systems who do not have a Pascal compiler to modify the flag themselves.
Simply rename the file to .OBJ and relink.  See DESCRIP.MMS for build procedures
or use MMS yourself.

Everything here applies ONLY to VMS V4.0 and beyond.  This code is currently
running under V4.5.  Do not expect ANY of this to have ANY bearing whatsoever
on ANY VMS system running ANYTHING prior to V4.0!!!  This may not work
when VMS 5.0 is released, I don't know yet.

I am not officially supporting any of this, but will be glad to see what
I can do to help if you have any troubles.  If you make any changes or
improvements, I'd appreciate hearing about them.

It should also be fairly straightforward to convert this to work
the DEC/shell UUCP.  You would need to modify RMAIL.C for incoming
mail and UUCP_MAIL.PAS' use of "uux" for outgoing mail.

This submission is an update of my Spring '85 UUCP_MAIL submission.  There
have been a few important bug fixes to the code.

Please don't contact me about getting our UUCP port that this was originally
developed for unless you already have an AT&T and Berkeley UNIX source license
and feel you really must have it.  We won't be using it much longer since
DEC now provides a UUCP with their DEC/shell product.  It does not have an
interface to MAIL, but the code here should be easily modified to provide
such an interface.  I would've liked to have done so for this submission,
but have not had the time.  (For the real reason, see the "Final Note:")

A final note:

We are in the process of switching all mail traffic over to the PMDF mail
system rather than this UUCP_MAIL code.  PMDF is a general-purpose foreign
mail delivery system available for VAX/VMS.  The PMDF mail system does include
support for DEC/shell UUCP as well as other delivery mechanisms.  PMDF is
available for the cost of distribution from:

	Ned Freed
	PMDF Project
	Harvey Mudd College
	Claremont, CA 91711
	USA
	(714) 621-8006

Before hacking this code to work for your mail delivery needs, you
ought to check out PMDF.  There's a good chance it already supports what
you want to do.
