--- Comment #3 from johannes schilling <claws-mail-bugzilla at deaktualisierung.org> ---
you're right, keys/certs don't neccessarily have addresses associated with
them, but many certificate authorities only sign S/MIME certs that have mail
addresses included and validate the email addresses.

so what i'm trying to say is: i know that it's not given that each certificate
has email addresses attached, but it's a use case many organisations i've been
to have and they require that i can't send an email in your name, signed as me
and have it get a green verification badge.

or, put another way: the way you see it, it's the S/MIME certificate alone that
verifies someones identity, and possible mismatches between mail addresses
(that i as a user see, but that are irrelevant to the protocol?) are to be
ignored; is that right?
