 Smime signing is ok. What fails is smime signing and encryption!

I reported a similar bug in april: 37025: 27.0.50; smime signing and encryption does not work any longer 

At that time there was a quick fix, namely :

There is however a quick «fix»


       (mml-secure-smime-sign-with-sender nil)
       *did not help*, although I am using smime not opengpg.
       But
       (mml-secure-openpgp-sign-with-sender nil)
       *did help*.

       This should be mentioned in the documentation (NEWS and in the
       relevant doc strings) 

Before it was finally fixed.

This quick fix does not work now. I thought of bisecting the problem,
but I have now time right now, maybe tomorrow night.

I will forward you such a message.
