Yes. To make it short, the message that mutt makes the gpg check against
is exactly what is contained between the "--boundary" lines. However, when you
save an "attachment", mutt formats/decodes the text as necessary according to
Context-Type.
For example:
- Headers are removed -- Content-{Type,Disposition,etc}:
- The text is decoded. So the gpg --verify might be executed against the base64
encoded message, but when saving the message itself, you get the pretty text.
- Not sure, but I also believe it would convert the text encoding to the
current locale.
To see the differences -- try "| more" when you're looking at the message, and
when you're looking at the attachments.
