Hi,
      I recently inquired different travel agencies through my Main privat
Email
      address. Ever since I get advertisement from Taiwan etc.
      The spam filter does not help since the senders addresses change.

      What I probably need is:

      A tool, which identifies all email of which the sender can not be
identified
      (of which I can not send a 5 MB anti-attack email back).

      Can you advise.I feel insulted here.

      Kind regards,

      Josef Laupheimer
