8.5 E-mail Security

Windows Mobile® protects your Outlook e-mails through Secure/Multipurpose
Internet Mail Extension (S/MIME) by allowing you to digitally sign and encrypt
your messages. You can also specify the access permission on your messages
and prevent unauthorized forwarding, printing, and copying.
Sign and encrypt your message
Digitally signing a message applies your certificate with the authorization key
to the message. This proves to the recipient that the message is from you and
that the message has not been altered.
Encryption protects the privacy of your message by converting it from
plain, readable text into cipher (scrambled) text. Only the recipient who has
the authorization key can decipher the message.
