I believe that mutt is incorrectly assigning the Content-Disposition
of PGP/MIME signature attachments as "inline". This causes some MUAs
(eg. gmail) to feel the need to display the attached signature inline,
instead of as an attachment. I believe that the Content-Disposition
should instead be set to "attachment", since that is in fact what it
is.
I notice, though, that the Content-Disposition is specifically hard
coded in the mutt pgp.c source to be "DISPINLINE" instead of
"DISPATTACH". I wonder why this is, since it appears to be a
deliberate choice. This seems wrong to me, but I would be curious to
hear a justification.
I am including a patch that changes the Content-Disposition for
PGP/MIME signatures to be DISPATTACH instead of DISPINLINE. This
patch has been tested and working in the lenny version of mutt I am
currently using. If there is reasonable justification for keeping the
default to be DISPINLINE, then I think we should make a patch where
the value of the Content-Disposition is set by a mutt variable,
therefore allowing users to easily change it if need be.
Thanks so much for maintaining such a great MUA. Let me know if I can
be of any further help.
jamie.
