Verbose means in Express a Mail is composed and shown as setup.
In non-Express versions we show the Login-Dialog for a new
session and after we have choosen the profile to use, the
composed email is shown before sending
Silent does currently not work for non-Express version. We have
no Session, no Login Dialog so the system refuses to compose a
new email. In Express Versions the email is sent in the
background.
