> Outlook/Hotmail blocks DigitalOcean. Microsoft blocking a mail server and DO being blocked aren't necessarily the same thing. I service a number of MS accounts (hosted domain and O/H/live.com) and they block mail from small servers I manage - and from (non-major) online services I work with. There are forums frequent that send verification mails to MS addys that never arrive. Past that: My last time blocking mail server attacks from DO IPs is today. It's always today and has been years and years. Not just DO. OVH, Psychz and a at least doz more attack with that consistency. [edit: Post below mentions DO SMTP changes in 2022. DO is still attacky but less attacky is possible. Not sure.] And not that far behind, Amazon. Amazon is a lot harder because unlike the above, I regularly get legit traffic from them.
