For the first time ever, I've got spam.

It's from 102.213.93.28 (AfriNIC) and there is no abuse mail in the whois output, only telephone numbers. What should I do? I can DM you the full headers/mail, if it helps.

Dear fellow #mailadmins, especially those who selfhost and offer the service to friends & family:

as you may know Microsoft stores the login credentials for remote (non-MS) mailservers on their servers instead in the clients. See https://mailbox.org/en/post/warning-new-outlook-sends-passwords-mails-and-other-data-to-microsoft

How do you deal with this kind of security issue?
