I also had to change a few servers to use a SMTP relay, being on block lists was taking up more and more of my time on DO. Some have never had issues that I’m aware of.
It would be good to see this as an official feature in MIAB honestly, not sure if there has been a discussion on this before?
Same as others on DO, hosting a mail server for many years in their Amsterdam datacenter without problems. I joined them even before they started blocking port 25 per default.
Oh yeah? but this doesn´t mean that you are not blocked by many, or most of your e-mails go straight to spam folders. I block anything from digital scum because I´m fed up getting tons of phishing and spam mails from their shady network.

UPDATE: DigitalOcean has worked with us to resolve this, and their IPs are no longer listed at MXRBL by default. The following is only useful for historical data.
