set up my own mail server.

Unless you are like a very skilled computer expert, don’t.

Use an encrypted mail provider + custom domain.

I just set up one on Tuta (#NotSponsored), and bought a two year for a .com domain.

I don’t know coding, I suck at most techy things. I managed to set it up by just… following instructions.

Register domain + Payment.

Go to Tuta, get premium plan.

Go to Tuta’s settings, set up Custom Domain.

Copy Paste all the DNS configuration stuff.

Voila, easy.

If Tuta goes rogues, I’d find another one, change settings.

If domain registar goes bad, I’d transfer it to another one.

TLDR: You’re better off just using a mail provider + Custom Domain
