It does not. I used to work for a non-profit that ran our own SMTP server, and we had issues with our subscriber e-mails getting marked as spam, mainly for Office 365 users. We set up DKIM, DMARC, and SPF, but it still happened. We ended up having to move to using Google's SMTP servers just so our e-mails would go through.
