Help, help not wanted email in my Inbox!

[Josef Laupheimer]

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
