A little odd seeing my name on someone else's message. :)  There are not
many Walters here.

My preference would have definately been to have a signature sign a part
before it is attached to an email.  In this format, mail programs that
save parts automatically (like what someone mentioned of eudora), the part
can still be verified.  It would still have been possible to sign a
multipart/mixed.  I am guessing there is a way to write a multipart mixed
to a file here.  It is definately not something that is usually done.  I
guess that doesn't make much sense.  Signing multipart would be about
equivalent to the current for signing the whole message.  And for programs
that automatically save attachments, it would not be possible to put
together the multipart to check a signature.

Basically I would like to sign a simple message (text only) by attaching a
signature that would work when checking only the text body (no mime
header).  Similar signatures could be made for each part.  The signature
should be against the format of the part when saved rather than the format
in the message.  I would at least guess that the CRLF would be used when
generating a signature for text parts anyways.

I suppose I could just start making my signatures in this way.  People
would not likely understand what to do with a signature, but most people I
write don't use pgp or gpg anyways.

Sorry this is probably not the correct place to discuss this, but I am
unsure where is, and the topic came up on this list.
