I've been trying for a long time to get our company's mail server send mail that will get accepted by the GMail spam filter. I have managed making it work for Yahoo Mail and Hotmail, sadly GMail is still marking our mails as spam.

I have configured DKIM, SPF, DMARC and verified our mail server IP address against blacklists. I also have pasted here the headers GMail gets when we send a mail.
