Hi @Matias Opertti ,

Welcome to our forum!

What's your account?

I found a similar thread mentioned that Mail Delivery Subsystem messages may be the spam. To protect your account, it's suggested that you could try to report the emails and block the sender.

If you are using an Outlook.com account, please kindly understand that the Outlook tag here we mainly focus on general issues about Outlook desktop client. It's suggested that you could post your case in dedicated forum for Outlook.com for more professional advice.

Thanks for your understanding and support!
