Centmin Mod Users: Email handling?


Active member
Now that Microsoft is no longer going to support custom domain email handing, I need to find another cost-effective solution. What do you all use for mail handling?
I'm thinking maybe I could set up a separate Digital Ocean droplet specifically for email? I run a small network of sites, so it isn't as simple as paying Google $50 for a single domain. I'd have to pay for 6+ domains every year.
I'm open to suggestions!
