OK. You raise an interesting point here, but I still think that there are
better ways to address it.
I want to point out that the reason that I did it the way that I did was
because the attachment header is NON STANDARD. I wanted to make sure that
I didn't break anything.
I didn't have your issues in setting up nmh. It worked out of the box.
It was way easier than competing mail systems and easier than most gui
systems. The thing that took time was setting up all of the mhshow stuff
for each mime type.
So two suggestions:
1. Add the -attach options for send and whatnow in the default profile
created by install-mh. Keeps casual users from having to deal with
it and doesn't break anything.
2. Create a program a la configure that scans a target system for programs
that handle content and build the mhshow stuff automatically. This
can't be hardwired because different things are available on different
target systems.

I'm confused here. My attachment code does all of this stuff automatically.
It guesses the content types, eliminates the need to know about mhbuild,
and eliminates the need to run mime. The only problem of which I'm aware is
order-of-operation stuff when wanting to add attachments to a reply to or
forward of a mime message in which you want the original message included.
What am I missing?
