dilemma: quoted-printables and signatures

Hash: SHA1

If I use a signature in e-mails like
- -----BEGIN PGP ...
Version: GnuPG v1.0.2 (SunOS)
Comment: For info see http://www.gnupg.org
...
=n3Oi
- -----END PGP ...

the last line (containing the equal sign) collides with quoted-printable
encoding (for 8bit characters).
The mail program can't decode the message because
it misunderstands =n3 (and the like) as an illegal quoted printable.
(My mail program is vm 6.75 (from Emacs) + mailcrypt 3.55.)

Any solutions? (using base64 encoding shows similar problems).
