Don't believe the armchair scare-mongering "experts" that will undoubtedly tell you in these comments that no big provider will receive E-mail from you.

I've been running my own mail servers for the last, well, 25 years or so. It's fine, if you get your own IP, don't get unlucky by inheriting one after a known spammer, and just keep a clean server.

Don't let other scare you into "having to use" Gmail or other huge ad-tech E-mail providers. That's not what the Internet was designed for.
