When mail users log in to Communications Express Mail for the first time, they encounter special prompts relating to the S/MIME applet.
When logging in to Communications Express Mail for the first time on Windows 98, 2000 or XP, the following prompts display:
If the Java 2 Runtime Environment (JRE) is not installed on your computer (client machine), you receive a prompt looking something like this:
Do you want to install and run “Java Plug-in 1.4.2_03 signed on 11/20/03 and distributed by Sun Microsystems, Inc.”?Publisher authenticity verified by: VeriSign Class 3 Code Signing 2001 CA
Click Yes and follow the subsequent prompts to install JRE.
If you desire English language support and also want to read incoming S/MIME messages that contain non-Latin characters, such as Chinese, the charsets.jar file must be in the /lib directory on your computer.
To ensure that the charsets.jar file is installed in the /lib directory, use the custom installation to install the English version of JRE. During the installation process, select the “Support for Additional Languages” option.
See Multi-language Support for more information.
Click Finish at the last installation prompt. Restart your computer and log in to Communications Express Mail again.
A prompt asking you:
Do you want to trust the signed applet distributed by “Sun Microsystems, Inc.”?Publisher authenticity verified by: Thawte Consulting cc
Click one of the following responses:
Yes, to accept the S/MIME applet for this Communications Express Mail session. The prompt displays each time you log in.
No, to reject the S/MIME applet. You cannot use the S/MIME features.
Always, to accept the S/MIME applet for this and all subsequent Communications Express Mail sessions. You will not see the prompt again.

There are initial signature and encryption settings that you can set to control whether all users’ outgoing messages are:
automatically signed, or
automatically encrypted, or
automatically signed and encrypted
The initial settings also control whether the signature and encryption checkboxes located at the bottom of a Communications Express Mail window and in the Options - Settings window are displayed as checked (feature turned on) or unchecked (feature turned off). Use the alwaysencrypt and alwayssign parameters in the smime.conf file to specify the initial settings.
Let your mail users know that they can change the initial settings for their mail messages. After they log in to Communications Express Mail, a user can temporarily override a setting for one message, or for all their messages on an on-going basis.
Table 20–5 summarizes the use of the checkboxes.

A variety of operating messages can be written to the Java Console by the S/MIME applet as a Communications Express Mail user processes signed and encrypted messages. The Java Console messages can be helpful when troubleshooting a problem reported by a mail user. However, operating messages are only generated when the Java Console is enabled for the user by adding a nswmExtendedUserPrefs attribute to the inetMailUser object class of their LDAP entry. For example:
nswmExtendedUserPrefs: meSMIMEDebug=on
Do not enable the Java Console for all mail users all the time because this significantly decreases the performance of Communications Express Mail.
