Bloquer des mails sur yahoo

Bonjour,

Je n'ai pas réussi à trouver un titre expliquant bien le problème.

Depuis quelques jours, je reçois des mails à caractère porno du genre prénom.nom@prénom.nom.us.

Or à nom et prénom ça change tout le temps et je ne sais donc pas comment bloquer ces mails...

J'ai trouvé ça come info sur le mail, ça pourrait vous aider à me proposer une solution?
