I happen to put in:

X-PGP-Key: 9A2FC99A
X-PGP-Fingerprint: CC3C 3A4D D593 3491 DA41  8FE9 3EDB B65E 9A2F C99A

which is, of course, excessive. I put the key in so someone receiving 
this can look the key up. I put a keyserver in there with the key 
correct, since many keyservers have mine either wrong or very out of 
date, and the fingerprint for what seems to me to be a very weak reason.

If I were to receive a GPG | PGP signed e-mail, I would still be in 
doubt if the person who sent it to me were really the person I think it 
was. And so far, WOT not withstanding (there is only one person in my 
WOT, and I do not know him well enough to be sure how strict he is with 
his signing other people's keys, and I know NONE of the people on his 
publically available key. So basically I have no web of trust. Of course 
none of my correspondents take security seriously anyway, and none have 
keys of either the PGP or VeriSign type, so I really get no use out of 
it other than trying to set a good example.

The only way that I can think of is to speak with the sender over the 
telephone, provided the sender is someone I know, and whose voice I can 
pretty unambiguously identify, and exchange a few obscure facts. Even 
then, though, I must assume such a person is not under duress, but I do 
not think I am _that_ paranoid.
