It works for me :)

You need to configure the smime_* options.
On my system the sample configuration file is under:
Just source/copy it in/to your neomutt.rc.

The default trust bundle is under:
Mine is a symlink to /etc/ssl/cert.pem
which is the Systems default ca-bundle.

Neomutt provides a tool named ``smime_keys'' to handle certificates.
It is not needed to just verify.

Yes, openssl has a smime module.
The sample file from above includes all openssl commands.
Just read it, it's documented.

Btw. to get gpg working, you also have to include gpg.rc
and change it to your needs.

I know, I should setup an PGP-Key and sign my messages already.
