"without authorization" is a quite well-defined concept in telecommunication
legalese in Europe.  Only the sender, and the recipients specified by the
sender are authorized.  The telecommunications service provider is NOT
authorized, and neither is an employer.

SPAM filtering MUST be implemented as voluntary opt-in, otherwise it will be
illegal, as you correctly notice.  Spam-filtering can only be legal when
it is performed strictly on behalf of the recipient, the receipient is
in full control over the behaviour all the time, and the blocking or
deletion of any messages is performed with explicit and voluntary
(i.e. condition-free) consent of the receipient himself.

A preselection to tag Mails as potential spam or to store potential
spam in a second inbox might be permissible, a preselection to block
or delete potential spam would certainly be illegal.
