Sign or encrypt a message
You must use a work email account that supports IBM Notes mail encryption to send an encrypted email message, or an
email account that supports S/MIME or PGP protected messages to send a signed or encrypted email message.
1. When you compose a message, slide your finger down on the screen.
2. In the drop-down list, tap a signing or an encryption option.
Note: If your BlackBerry device is associated with a CRL or an OCSP server, when you add recipients to an encrypted
message, your device tries to retrieve a certificate status for each recipient. You are unable to send the message until
certificate statuses are received for all recipients. If certificates can't be found or are invalid, the recipients' names appear
as red.
Update secure email settings
Depending on your permissions, you can change the email security that is used for all the messages you send. For
example, if you use S/MIME to protect your messages, you can send clear-signed messages that any email application can
open, or opaque-signed messages that only email applications that support encryption can open.
