In Enigmail I am removing the "S/MIME Security" button in the message
composer according to a user preference when displaying the window. Have
a look at the first lines and the method enigMsgComposeStartup in
http://www.mozdev.org/source/browse/enigmail/src/ui/content/enigmailMsgComposeOverlay.js?rev=1.119&content-type=text/x-cvsweb-markup
