Add an "encryption" option 'use_transport' which does not bother with
encryption and just relies on transport security.
For admins this makes sense as none of the admin messages is really
confidential.
This is also a valid option for a subscriber and makes some sense in
scenarios where the mail provider manages the subscriber key (sic!)
and does server side decryption. Think twice before using this.

This allows setups where there is no S/MIME. In some scenarios using just
GPG is fine and S/MIME might even be discouraged. Previously this required
to provide a dummy S/MIME key just to make remail happy. With this new flag
there is no need for that key if S/MIME is not required for the list.
