antispam per Thunderbird

[franco causio]

Io uso Thunderbird per la posta.
Sto ricevendo da qualche settimana email fastidiosi con Inviti Amazon chiaramente farlocchi. Il problema è che l'indirizzo email cambia ogni volta e quindi non riesco ad inserire un filtro sul mittente.

Se entro nei messaggi con CTRL+U vedo:

Return-Path: <[email protected]>

oppure in un altro uguale:
Return-Path: <[email protected]>
Delivered-To: xxxxxxxxxxxxxxxxxxxxit
