Well, John, why is it then that when I sent an encrypted and signed
message to this other Gmail account of mine without Enigmail, and
clicked on Privacy Tray's "clickboard" -> "decrypt/verify", the message
is both decrypted and verified as with good signature? If the message is
altered through the webmail system so that its signature can't be
verified, why is it that when it's encrypted it can both be decrypted
and verified?

Thanks, John, for the earlier reply.
