 * Resolved recipients in this API means a recpient could be resolved
 * to a single useful key. An unresolved recipient is a recpient for
 * whom no key could be found. Import / Search will be offered for such
 * a recpient. Multiple keys for signing / recpient can come e.g. from
 * group configuration or Addressbook / Identity configuration.
 *
 * The Dialog uses the Level System for validity display and shows an
 * overall outgoing level.

     *                             but configuration may allow more.
     * @param resolvedRecp: A map of a recpient address and the keys for that address. Multiple
     *                      keys could for example be configured through Address book or GnuPG
     *                      Groups.
     * @param unresolvedSigKeys: A list of signing addresses for which no key was found. Should
     *                           usually be only one. If resolved and unresovled sig keys are
     *                           empty it is assumed signing was not selected.

     *                        resolved recipients are empty it is assumed no encryption should
     *                        take place.
     * @param senderAddr: The address of the sender, this may be used if singing is not
     *                    specified to identify a recpient for which "Generate Key" should
     *                    be offered.
     * @param allowMixed: Wether or not the dialog should allow mixed CMS / PGP key selection.
     * @param proto: A specific preselected protocol. If Protocol is unknown it will allow
     *               both (depending on allowMixed) S/MIME and OpenPGP.
     * @param parent: The parent widget.
