mailx docs.

[Jeff Stuart]

The header says it all.  I would like a GOOD in depth discussion of mailx for
System V.2.  I have RTFM but it doesn't really talk about folders and some of
the more complicated commands that you can have in your .mailrc.  I am running
on a Plexus P/75 running Unix System V.2.

		Thanks and I will summarize if there is enough interest.
