The netblock thing has happened to me. My Linode that I’ve had sending mail for 6 years gets blacklisted now purely for being on the netblock that it’s on.

- apocalyptic0n3 4y agoYep. I've encountered the exact same issues on multiple Linode servers in multiple data centers. I've also experienced it with an AWS server. It's often almost impossible to get it unblocked because the support teams at the email providers (if you can even contact them) don't realize that's what's happening. I didn't understand it myself until I got a call with an engineer at Microsoft who realized it in the middle of our call. He unlisted us on the call and we were fine for a while, but were eventually blocked again and haven't been able to get unblocked. It's really frustrating and I'm slowly ending all of my email services (both professional and hobby) as a result.
