When displaying an email that contains a digital signature, it will show the email\u0027s date. If the dates were different, Thunderbird didn\u0027t report the email as having an invalid signature. If an attacker performs a replay attack, in which an old email with old contents is present at a later time, it could lead the victim to believe that the statements in the email are current.
