Ask HN: What cloud providers are suitable for running mail servers

4 points by o8r3oFTZPE ↗ HN
Conventional wisdom is that home internet service provider IP address blocks are unsuitable

Does same wisdom apply to cloud service provider IP address blocks

You're going to have deliverability issues with Gmail no matter what if you roll your own. I had ran my own mail server with SPF/DKIM/DMARC/etc. for 15+ years, all setup correctly and still had no guarantee that messages would inbox. I finally gave in and switched to an offshore 3rd party service for hosted emails to keep the "I wonder if that important email actually got delivered to their hosted Gapps" at bay.

But you cannot/will not name the offshore 3d party service

Try protonmail.com, zoho.com or fastmail.com

Same as the op, switched from self-hosted to fastmail.

Most cloud providers block outbound smtp traffic

No matter which provider you choose, your emails will be misclassified just because you're a new host sending email on the internet.

Over time, your server will build reputation by not sending spam and emails start to reach inboxes.
