Outlook.com not receiving emails sent from my Digital Ocean droplet
I am running Ubuntu 14.04, my mail server is dovecot 2.2.9 and postfix 2.11.0 is the mail transport agent.
I am having an issue where the mail server successfully sends email notifications to the likes of gmail and yahoo but we fail to get any mails to outlook.com email addresses.
We have checked for being blacklisted, which we are not. I have seen other posts with similar issues but no one coming back saying that they have sorted this issue. Surely someone has setup a DO mail server that can send mails to an outlook address. Any help greatly appreciated.
