Otherwise, how can you be sure that the email address you just signed is correct?
You don't need to know that it's correct. The purpose of your signature is not to say “this is a correct email address”, since that can change at any point in the future. Rather, the purpose of your signature is to say “I met this person, verified they are who they say they are, and this person tells me this is their email address and public key”. You're recording a historical fact, true for a point in time, not guaranteeing that any particular thing will work in future. -- \ “Beware of bugs in the above code; I have only proved it | `\ correct, not tried it.” —Donald Knuth, 1977-03-29 | _o__) | Ben Finney
