Again, thank you very much for your time. I have got it now. I will just
use S/MIME to communicate with that partner.

Please see my previous post for a detailed explanation why I have been
worried so much (although it has been clear to me since a long time that
S/MIME and PGP are different things).

To make a long story short, my partner first asked me if I would like to
use PGP or S/MIME (I answered "PGP"), and then claimed that the
certificate he provided was a "PGP certificate".

Furthermore, I wouldn't have come to the idea that gpgsm handled S/MIME
certificates (although I am now understanding why it is named gpg>SM<
:-)). In my naive world, GnuPG software (and gpgsm obviously falls into
that category) dealt only with PGP, not with S/MIME. Worlds change ...

For that three reasons, I did not even consider that the certificate my
partner provided could be an S/MIME certificate, but believed that it
would be some sort of a "new, modern PGP certificate". If I only had
known that earlier ...

Sorry for the lengthy posts, and again: Thanks you very much!
