Hi!
I went into the PGP data formats and managed to persuade GnuPG
to create signed and encrypted messages which can be verified and
read by PGP 2.6.x versions - really common in the German university
area, where a certification infrastructure based on this software
is currently created.
The new script doesn't use a separate gpg-options file and
works fully automatically: It encrypts PGP 2 compatible if all used
keys are of type RSA, and can be configured to use RSA when signing
only. Included is short installation information and a tutorial what
steps are required to manually sign-and-encrypt files for PGP 2.
Script is still available at

GnuPG 1.0.0 (which is really nice IMHO) resides here:
http://www.gnupg.org/
Maybe it's worth adding a note somewhere on the mutt www site.
