I changed the MX records to use Ionos server and it didn't resolve the problem. Again, I don't know if I did it correctly as I only changed DSN records.
One interesting point, is that when I use Ionos webmail (with mail services that run on my server), the email is sent to Hotmail but marked as spam but when I do it directly from a PHP script, it bounces back with the same issue.
Any idea about the reason?
