Well you are right. She's the one with a non RFC-compatible mailer.
But this won't help you as most of the people round there are using
exactly this MUA.
By default Mutt uses PGP/MIME for signing and encrypting Messages as
described in RFC 1847. But most of the windows mailers (alle except
Eudora I think) cannot deal with PGP/Mime, so they will get an empty
message with two attachments. If you save these attachments to a
file, you'll be able to check the signature and read them using some
functions of PGP's GUI, but this means much effort.
What are possible solutions to this problem:
- If you know, what MUA the person you are in contact with is
using, you can use the old-style PGP format that is understood
e.g. by MS OE. I defined some macros in my muttrc to do so
macro compose S "Fgpg --clearsig=on\nj^T^Utext/plain; format=text; x-action=sign\n"
macro compose E "Fgpg -a -e -s\nj^T^Utext/plain; format=text; x-action=encrypt\n"
- And messages to mailing lists I do not sign or encrypt normally.
Signing is not as useful there as in private or business
communication and you can reduce the size of your messages and
also avoid trouble
