Sending email out is a royal pain. Trying to deal with a Microsoft ban on my IP even though it’s sparkling clean for several years. DKIM, DMARC, SPF etc all ser up, reverse dns, you name it. Looks like Linode is being blocked as a whole pretty much? Hate the level of centralization, particularly since there’s still a shit ton of spam still around. Sorry for the rant. https://docs.microsoft.com/en-us/answers/questions…
Wouldn't surprise me if Linode were entirely blocked. Also anything in M247 Ltd's ASN. They host a lot of VPN endpoints, including Mullvad's. Step 1, I'd move off Linode. Find a local DC or business you can support by hosting a VPS or dedi box with them. LowEndBox might be an interesting place to search but avoid anything too famous. Step 2, join this https://sendersupport.olc.protection.outlook.com/pm/services... .…
I'd be very surprised. I hosted email on Linode for years without issue.
