What is 'format=text'?  RFC 2646 only describe 'flowed' and 'fixed' as
values for the 'format' variable.

I believe using either PGP/MIME (RFC 3156), or inline PGP within
text/plain parts, is more likely to work, than (like your MUA does)
using inline PGP within application/pgp.  The content type
application/pgp is not even registered with IANA, as far as I can
tell.
