Configure Secure e-mail

Make sure that you have installed Mozilla Thunderbird and have configured it to send and receive e-mail through your e-mail server. The presence of at least one digital certificate is required before you can proceed with the following instructions.

Note: If you do not yet have a certificate that can be used for secure e-mail, please obtain a certificate before you continue the configuration steps described below.

Mozilla Thunderbird

  1. Start the Mozilla Thunderbird.

  2. Click on Tools > Account Settings... to open the Account Settings panel.

  3. Click on Security in the left pane under account name.

  4. Click on the Select... button in the Digital Signing section to define the certificate to be used for e-mail signing. A list containing all available certificates appears. Select a certificate, then set the signature using the setting Digitally sign messages (by default).

  5. In the Encryption section, the default encryption behavior can be configured.

  1. Select Never (do not use encryption) when you want to define the encryption behavior on demand.

  2. Select Required (can't send message unless all recipients have certificates) to have all your e-mail encrypted automatically.

The configuration of PKCS #11 is described in the section configuring PKCS #11 for Mozilla Firefox.
