Yes, that is true. However, if i remember correctly gpgsm by itself does not produce
a message body format for an an email which looks like those created from other
S/MIME capable email clients.

While i also played with S/MIME and PGP setup's in Mutt long time ago, i am
using now for regular S/MIME email communications Thunderbird. I also
remember vaguely that for those (Neo)Mutt S/MIME set-up gpgsm was not
required. 

I would suggest that you simply google for "Mutt S/MIME" to see a lot of
tutorials on how to do that. Once you have a correct neomutt set-up
you can send me an S/MIME signed email so that we can see if your
set-up works properly. I have a D-Trust certificate. The D-Trust
root certificates should be already installed in most systems.
