While three options are available ("None", "If Possible", and "Always"), the "If Possible" option is not able to be selected. Forcing the selection by manually editing prefs.js user_pref("mail.identity.id2.encryptionpolicy", 2); becomes user_pref("mail.identity.id2.encryptionpolicy", 1); causes the option to be selected but greyed out, and SMIME encryption does not happen even when it should be possible. The option is also not able to be selected in a Message compose window when going to Options | Security . This may be somehow related to defect 115962 and the migration of encryption preferences from earlier nightly builds. Moz. nightly 2002010206, Linux i686.

The pref has moved from a boolean to an int, but the code still treats it as a boolean. The s/mime functionality is still only all or nothing.

Too bad the boolean can't be switching between "None" and "If Possible" until the rest of the code can be made aware of the preference's integer nature.

S/MIME bugs are automatically nsbeta1 candidates. (this is a bulk update - there may be some adjustment of the list).

While we want to have this feature, and the UI is already prepared, we have not yet implemented the "if possible" behaviour, therefore this does not track a bug, but an enhancement. Let's keep this open as a reminder.

We're removing if possible

This is now a duplicate of bug 129100, because I'll remove that setting with that bug. Next time we attempt to implement that, the "if possible" UI and corresponding logic will be done in a single step. *** This bug has been marked as a duplicate of 129100 ***

Verified dupe.

*** Bug 135636 has been marked as a duplicate of this bug. ***

Kai, is there an open bug for the 'if possible' option now ?
