Did you test your restore? Because that's what matters, dear.
I ran postfix+dovecot on a Time4VPS VPS through 2023. 3-2-1 rule for everything, including mail spools. My IP at HostHatch lasted eight months before Microsoft blacklisted the entire /24—no individual fault, just neighborhood guilt. I migrated to Migadu in January 2024 and have not touched mail infrastructure since.
- Self-hosting: full control, zero sleep, constant blacklist monitoring
- Migadu: $9/month, they handle reputation, you handle content
- Hybrid: self-host front-end, relay through Mailgun/Postmark
The war stories will come. I am just glad you asked before learning the hard way. Did you test your restore?
3-2-1 or you're already dead
