I assume he meant free like speech, not free like beer.
There are no gatekeepers to email, anyone can get a domain and their own server.
There are definitely gatekeepers. Even if your hosting provider isn’t blocking port 25 by default, SPF, DKIM and DMARC will see your emails going straight into the recipient’s junk folder/spam filter if not correctly configured. Hosting your own mail server at home is also a fantastic way to piss off your ISP, lose emails to downtime, have your IP blacklisted from many services and open up your environment to exploitation. It can be done but let’s not pretend that it’s easy or that there aren’t barriers to entry.
Mail servers are like filo pastry. Sure, you could go to the inconvenience and effort of making it yourself and I’m sure it’ll be very satisfying to do so. But 99% of professionals use the store bought version, and for good reason, because it’s a lot of effort for an end result that is no better and in all likelihood probably worse.
Mostly agree, but as someone who has been hosting my own email for years I can tell it is, in fact, better.
Quick note for hosting one on a residential IP - that would no longer piss any ISP off. You would simply not deliver anything anywhere due to IP being blacklisted by default.
SPF, DKIM, and DMARC would like to have a gatekeeping word
Blacklists, greylists, whitelists. All just a big fuck you from the big vendors to anyone trying to self host.
If you don't know what you're doing, hosting an email server will not be a good time. It's very easy to produce an environment that is easily exploited.
A somewhat inexpensive shared hosting plan allows you to host your own email though. I get it done for <$100/yr. and have little to no limitation over self-hosting.
You try that once, but it doesn't last.
