[net.mail] MH vs. /ucb/mail?

jww@sdcsvax.UUCP (Joel West) (10/04/85)

The /usr/group newsletter, reporting on the Portland USENIX
BOF on BSD 4.3 (sorry for the staleness, but some of us don't 
make it to conferences and have to read all about it) noted that
4.3 includes MH, and I quote

	MH.5, a mail handler, provides network users
	with a more efficient way to read mail.  This set of
	programs uses a number of UNIX utilities, and
	supplements the mail program used by 4.2.  The
	4.3BSD release will contain both MH.5 and mail.

Sure 'nuff, there it is in /usr/new/mh/xxx.  'man mh' produces
some mumbo-jumbo.  The difference that's immediately apparent
is that the MH commands are invoked at the UNIX command level,
rather than within a mail subsystem.

Two questions:

	1) In what ways is MH better or worse than /ucb/mail?
	   Does it, for example, directly support new standards
	   in internet messages?  X.400? etc.

	2) At one point, I thought a MH source was available,
	   unlicensed.  Is one available for use by systems
	   for upgrading of archaic mailers (/bin/mail) or
	   non-UNIX systems?  (VMeSs...)
