PGP 6.5 is extremely deprecated.  Standards change over time and in the
case of PGP 6.5 a lot has changed.  In fact, there is even a New
'Standard' in the form of RFC4880.

The 'problem' is _not_ with Enigmail because it contains on encryption
engine of any sort; it is simply a Frontend for GnuPG and merely passes
commands to gpg.exe which is responsible for verifications, error
messages, etc.  My knee-jerk reaction is that the Settings within
Enigmail have not been configured to 'throttle back' the use of Hash
algorithms unsupported by PGP 6.5  If I am correct then PGP 6.5 will not
verify the Sig on this message but any current version of GPG will.

My proposed solution would be for You to immediately switch from PGP 6.5
to a more current version of OpenPGP.  :-\
