Steps to reproduce:

In the settings of an eMail account I chose not to send a message if all recipients do not have an S / MIME certificate (see attachment).

Unfortunately, this choice is ignored, in fact if I write an email to a user who does not have a certificate is sent without showing me any warning message. If I send an e-mail to a user without a certificate, the e-mail is sent without showing me any warning message.


Actual results:

You can send eMails convinced that the encryption works, but it will actually be sent in clear text.

For clarity, the English version wording is
 Default encryption setting when sending messages:
  * Never
  * Requuire (can't send message unless all recipients have certificates)

Reporter, do you have the Enigmail Add-on installed?

To clarify the intended behavior.

The preference is a "default" value for new messages. If you enable the preference "default = require", and compose a new message, then the message has encryption enabled.

I tried to reproduce your bug (without Enigmail installed). I set the pref. I compose a new message. I enter a recipient for whom I don't have an S/MIME cert. I send the message. I get an error message, preventing me to send.

Still in the composer window, I can use the menu to disable encryption for this message. Then I can send the message. This works, and is intended behavior.

With the Enigmail Add-on installed, and the default set to OpenPGP messages, the S/MIME pref is ignored. Enigmail seems to override the default configuration.

(In reply to Kai Engert (:kaie:) from comment #3)

I tried to reproduce your bug (without Enigmail installed). I set the pref. I compose a new message. I enter a recipient for whom I don't have an S/MIME cert. I send the message. I get an error message, preventing me to send.

This means, I couldn't reproduce the reported bug.
