If you’re running your own domain and mail server with everything validated via SPF and DKIM etc then this layer of spam filtering won’t do anything. Other spam filters like AI-based ones that look at the contents of message for spammy stuff need to take over after that point.
Fighting spam is constant cat-and-mouse battle and you’ll never truly get rid of all of it.
