Hi Walter, thank you very much for your answer. I finally found the solution yesterday, but I did not know how to "close" this issue I submitted.
I explain my solution just to check if is seems Ok to you : - I changed the openssl smime command to remove all header part - I insert the header after smime commands (at the beginning of the file) with simple text editing / inserting - Then I send it directly with : sendmail -ti < my_file_encrypted_with_my_new_headers I understand your point : "Disposition-Notification-To" in EVERY email but here it's only for a project for a server to server communication where I need to get the notification back for further operations.
