The GroupWise client accommodates users’ preferences for security and privacy when sending messages. Users can do the following:
Sign a message with standardized text (GroupWise client >> > > ).
Sign a message with an electronic business card (vCard) (GroupWise client >).
Digitally sign and encrypt a message. See Section 90.1, Personal Digital Certificates, Digital Signatures, and S/MIME Encryption.
Give a message a security classification (GroupWise client >).
Conceal the subject of an email message (GroupWise client >).
Mark messages and appointments private so that proxy users cannot see them. (GroupWise client >).
Attach a password-protected document to a message and have the application prompt the recipient to supply the password before the recipient can open the document
Require a password in order to mark a Routing Slip completed (GroupWise client >). This can prevent a user who is proxied to the mailbox from marking the item completed, or if multiple users proxy to the mailbox, it can be used to ensure that only the user for whom the item was intended can complete it.
In addition, if the users in your GroupWise system exchange messages with users in other GroupWise systems, you can set preferences to control what types of information pass between the two systems. For example, you can prevent external GroupWise users from performing busy searches or obtaining message delivery status. See Section 4.20.3, External Access Rights.
