email – All checks are over – Mail is always sent to spam

This question already has an answer here:

I have a self-hosted mail server using nethserver.

Whatever I do, the mail I send remains in junk mail on Gmail and Office365.

This is an exclusively personal mail.

My IP address or domain is on a blacklist.

check-auth@verifier.port25.com results:
