Synchronising Information and Setting Up Email Security
4.5 Setting Up E-mail Security
Windows Mobile on your Ameo 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 authorisation keys and certificates, S/MIME allows you to digitally sign
your e-mail messages to prove your identity to the recipients. Authorisation 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 to decrypt it.
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
synchronised, these options are unavailable.
Digitally sign and encrypt all messages
ActiveSync allows you to set up S/MIME e-mail encryption and signing. You must
obtain a valid certificate to sign and encrypt e-mail messages successfully.
