Who is doing S/MIME enveloping in KMail - gnupg2 or KMail?

It must be a KMail problem.  I know that it used to work very nicely all
the years since we started the S/MIME support about 10 years ago.  Thus
I assume there is a regression in KMail.  I don't have a current version
running here for a quick test.

GnuPG (i.e. gpgsm) does not know anything about S/MIME - it merely
creates data according to the CMS encryption/signing standard.  GPGME
(the library between KMail and GnuPG) also has no knowledge about
S/MIME.  KMail is responsible to pack that into a MIME structure.
