Hello, I've been looking why this happens for lot of time and I just noticed I just need help. Using https://www.mail-tester.com I get a score of 10/10, what's worng? My xenforo can't connect to the SSL port and using roundcube also marks the emails as spams, also my server is not blocklisted by any page
There must be spam keywords present in your email body so try to identify it and replace.
