On: Moving 12 years of email from GMail to FastMail

Are you on a dynamic IP? I used to run a mail server on a dynamic IP, and many people will be butt-hurt about it and block you on sight.

The IP address change was from spinning up a new server on DigitalOcean.

From what I could gather, changing the IP on a mail server is seen as suspicious and resets your reputation level. Google handles this by “safely” marking all of your mail as spam, I guess until your reputation is restored, which is nearly impossible since nobody will see your mail.
