XF 1.5 Email Marked As SPAM in Gmail

So all emails coming from my forums are going straight to the Spam folder in Gmail.

I have a VPS through KnownHost. DKIM and SPF are enabled and configured and pass when looking at the original email in gmail. I have other domains on this VPS (1 ip) and are configured the same way using SMTP and don't have any issue.

Any ideas? Thanks
