Why? The email client already displays the details of the primary UID as pa=

of the good (or bad) verification, as long as the public key is available.=

You don't have to take any notice of From:

Not true. Why make this part of GnuPG when the 'problem' is clearly user=20
related? I don't have any experience of what you described as 'often' - bla=
nk=20
subject lines are just plain rude (make scanning an inbox for important mai=
l=20
from new correspondents more difficult) and users who do this should simply=
=20
be told to mend their ways.
If someone doesn't repeat the 'vital' information contained in the subject=
=20
line within the signed message, disregard it and then ask them why.
