I know that it depends on the system; this is why I wrote the email since I think that here are people that know GnuPG in combination with several email clients... Let's break down the problem: A and B have public keys on some keyserver. A has no email address in his public key, B does. AFAIK there are these four use cases concering emails and OpenPGP: 1: A sends a signed email to B. 2: A sends a (signed and) encrypted email to B. 3: B sends a signed email to A. 4: B sends a (signed and) encrypted email to A. Use case 1 and 2 should be no problem. Based on the key information saved in the signature the email client of B should get the public key of A. The email adress does not matter. Use case 3 should also be no problem since it does not deals with A public key. Use case 4 is the problematic one, B's email client does not know anything about A. B's email client could search for A fore- and surename on a keyserver... What do you think?
