3.6 Setting Up E-mail Security
Windows Mobile on your phone protects your Outlook e-mails
through Secure/Multipurpose Internet Mail Extension (S/MIME),
which allows you to digitally sign your messages as well as
encrypt them.
Using authorization keys and certificates, S/MIME allows you to
digitally sign your e-mail messages to prove your identity to the
recipients. Authorization keys are also used when encrypting
messages to improve privacy and prevent undue tampering or
hacking of your messages. You can encrypt a message with or
without a certificate. However, to read an encrypted message,
you need a valid certificate for decrypting e-mail messages.
Note
S/MIME encryption and digital signatures for Windows Mobile-
based devices are available only with Exchange Server 2003
Service Pack 2 or a later version that supports S/MIME. If you are
not using one of these products, or have not yet synchronized,
these options are unavailable.
Digitally sign and encrypt all messages
ActiveSync allows you to set up S/MIME e-mail encryption and
signing. You will have to obtain a valid certificate for signing or
encrypting e-mail before you are be able to sign or encrypt mail
successfully.
