Plesk mail, spam outlook/hotmail & co

Hello,
I'm busy in recent days setting mails on my Plesk server (Centos 7.2 - OVH)

Everything works fine, I also made the mails settings on my domain (DomainKey and install spamassassin, and SPF)

I use the roundcube webmail to send emails.

I can send emails and everything works fine unless I send in outlook.com, hotmail.com & co ....

When I send to outlook.com, hotmail.com the mails go directly to spam

I do not understand why.

I use email-test and it tells me a 10/10 rating, dnsinspect...
