By default, I want my notes internal mail messages signed, but I do not have or need a certificate to sign internet messages.

 

When I try to send an internet message, a dialog pops up asking me whether it is okay to send the message anyway, having asked to sign it while lacking a certificate. So far, so good. It is easier to hit that OK button than fiddling with delivery options each time in advance, which I'll forget anyway when in a rush.

 

What annoys me is that the message sent after leaving that dialog is adorned with an X-MIME-Track header shouting my notes-internal name and how S/MIME signing failed due to some certificate not having been found. But nothing failed. I chose not to sign that message after all. I would rather that unsigned unencrypted messages did not get such a header at all. Such details are not for the eyes of outside recipients.

 

Notes should clean outgoing internet messages of all S/MIME traces when user interaction has caused it to drop S/MIME behaviour.
