iNotes - VOP and sMime to send encrypted email?

We use the signed and encrypted functions with our Notes clients.
We have integrated a smime certificate into the user id.
No hassle sending with the Notes client.
We then integrated an internet certificate from one of our senders into the person file with the Notes client.
in consultation with iNotes, we see the presence of this certificate (nothing with VOP) but no information on the origin
Error when we send an email with both (inotes and VOP)
messages leave signed only.
How to have this feature in http mode ?

Domino 12.0.2 - VOP 3.0.1

What exact error are you getting?

Also you are accessing the server via HTTPS, not HTTP, correct?
