Fixing SMTP problem

Hello We've a problem and need someone to correct this. We are running dedicated server under Windows 2003. We are using mailenable 3 Pro mail server. Most of our emails goes to Spam in GMail.? Need a fix. I'm attaching sample email from gmail. Everything looks fine - SPF and DKIM pass, but still goes to spam.? Thanks. Waiting for your suggestions and looking for person to correct that. We don't need you to send any emails. We need to find why our NEW server and new domain emails looks like spam to google. We are not going to send spam, that's a regular company email server.
