Is this in the main message header, or one of the MIME sub-parts?  As far
as I know, it's totally RFC-legal to insert or remove line-breaks in long
header lines.  If it's in the main header of the message, I woudln't think
gpg would be signing that part anyway, because the headers are guaranteed
to change, if nothing else than by addition of a Received line, but
possibly by other mechanisms as well.

These are things that Yahoo's "Domain Keys" and the more recent replacement
were designed to be able to handle, AFAIK, so you might want to look there.

Thanks,
Sean
