Hi, > other people could verify it.

The error message when opening Message-ID: <1447719799.6941.4.ca...@scientia.net> is Couldn't verify S/MIME signature: certificate verify error The header Content-Type: multipart/signed; micalg="sha-512"; protocol="application/x-pkcs7-signature"; boundary="=-q9gdJ6oE7VoDos3CeFlt" brings me to https://www.rfc-editor.org/rfc/rfc2311.txt https://www.rfc-editor.org/rfc/rfc2315.txt where i stand somewhat clueless.
