Client is receiving multiple e-mails from one exact spammail

Occasional Visitor

Hi, 

 

Our customer uses office 365 and recently received a spam email, only now that email continues to flow in with the exact times it's send from. For the past few days they have been getting about 10/20 emails from the same sender and content every second and it adds up to thousands of emails. SMTP, Captcha and an antivirus is set up. Until now the mails keep pouring in, has anyone had the same kind of problems or is there a solution?

 

Kind regards!

@Berto2715 you need to configure an anti-spam policy for your inbound to block such spam emails coming from a specific sender. Please refer to the below link
