In the past, I used Neil Rickert's scripts which are at
http://faculty.cs.niu.edu/~rickert/mh/
They worked fine for simple text e-mails (i.e. no attachments) and are
probably newer that the mh 6.8.5 things.

I've got a rather more rudimentary script for checking signatures which
I have attached. I think it broke with nmh 1.6, it used:
mhshow-show-multipart/signed: sigcheck %a %F
I think the breakage relates to defining that for the multipart/signed
part rather than for application/pgp-signature. Ideally we'd want to be
able to do something like
mhshow-show-application/pgp-signature: gpg --verify %F %r
where %r is the related content suitably converted to have DOS line
endings (yuk). I think there's an RFC covering multipart/signed.
