This has literally just recently (re-)become an issue for me because after a good year or so of not being blocked, several emails from my server started getting filtered as spam by both Google and then just being outright blocked by both Google and Microsoft. When I got through Microsoft's steps to unblock, after several days and steps, they send me the message that actually my IP is not blocked. Google's recent message was more helpful - apparently forwarding emails from the accounts I setup for my kids to my wife's Gmail account triggered some obscure rule that ruined my server's reputation with Google, and I think Google & Microsoft collaborate because the issues cropped up within a week of each other. The interesting thing was I discovered the Outlook issue by trying to reply to an email sent from an Outlook customer. Yes, my reply to an Outlook customer's email to me was blocked because of my server's reputation. To be clear, I run no mailing lists nor solicit any business with my email server. I use it for personal use only and my consulting work which involves know contacts. The forwarding I spoke of before is solely to our own personal accounts. I use Mail-In-A-Box, for what it's worth, on a Linode VPS.

How did you contact Google and Microsoft regarding deliverability issues?

  Microsoft: 1. Set up on https://sendersupport.olc.protection.outlook.com/snds/ https://sendersupport.olc.protection.outlook.com/snds/ 2. Read everything at https://sendersupport.olc.protection.outlook.com/pm/ https://sendersupport.olc.protection.outlook.com/pm/ 3. Make sure everything is fixed, then use the link to the form hidden under Troubleshooting > "Sender services, tools, and issue submission" (the link's label is "here") to contact support. Make sure all fields are provided, including a website. It may take a few days to get a response. You may have to try multiple times until someone actually helps you. Google: Pray

    This is a fair reflection of my experience.

    You failed to mention that if you haven't managed to complete this successfully(google also has a similar form: https://postmaster.google.com https://postmaster.google.com), google will just mark it as SPAM, but outlook will *silently* drop your mails.

      Both google and outlook can drop your mails without delivering them to the recipient, but you can find the rejection error code in your MTA logs. Though it's true that microsoft just rejects everybody and google might not reject you at all, at least outlook has a procedure of sorts these days. I do not see any form at postmaster.google.com that I'm allowed to access.
