Bug with digitally signed/encrypted emails
Summary:
In Lion, inbound emails that are digitally signed and/or encrypted do not contain any indicators that show that the email is encrypted and that the sender has digitally signed it.
Even worse, if the contents of a digitally signed email have been altered, Mail does not display any warnings that the message has been tampered with.
Steps to Reproduce:
Send an encrypted and digitally signed email. It will be received without any indicators saying it was signed/encrypted. In addition, alter the digitally signed email source with a text editor, and then send the email (using telnet commands) to the mail server. When received, Mail does not warn the user that the email was modified.
Both of these issues were not present in Mail under Snow Leopard
Expected Results:
Digitally signed/encrypted emails should have visual indicators to show it (see screenshot below showing same email in Lion and a different client). In addition, digitally signed emails that were altered must cause mail to warn the user about the tampering.
Actual Results:
Mail does not show that an email is signed/encrypted. Mail does not show that a digitally signed email has been tampered with.
Neither of these two issues were present in the Mail.app in Snow Leopard.
Anyone found a solution....?
