My thought is to pgp sign my mail.

Those who know me, who have spoken to me over the phone and have
received mail from me, can save my signature from my mail and know the
mail, and any future mail with that signature, is from me.

Those who do not know me will have a valid, verified, but untrusted
signature.  If these people have a problem with my mail, they should be
able to track me down through my signature.

If one receives mail that purports to be from me, and doesn't
have a signature or does have a signature, but not my signature,
I can claim I didn't send the mail, and hopefully, the person
who created the signature can be tracked down through their
signature.  I assume the key servers keep a log indicating what Internet
address was used to register what signature and those records can be
accessed if one can get a court order.

I try to register my pgp signature with either keyserver.pgp.com
or pgp.mit.edu:11371 or subkeys.pgp.net, whichever key server seems
to be accessible at the time.  I believe, the key servers synchronize
amongst themselves so I need only register with one key server and the
rest will eventually get my signature.
