I’m fairly new and don’t 100% understand it yet, but instances are run on servers that require money. Are we heading towards seeing ads or subscriptions to raise funds instead of relying on donations to cover overhead?
Especially with the influx of new users. Hardware upgrades are needed.
You can, but as I said, because you aren’t a know provider every message from your server will end up in the spam folder of everyone using Gmail.
You won’t have a functional system unless you back it with either Gmail or Outlook.

It’s interesting to hear your take as someone experienced, because on hobbyist forums like /r/selfhosted I used to hear the complaint above all the time. Maybe people aren’t doing things correctly. I’ve never messed with my own email server and have no dog in this fight, but I’ve definitely heard that complaint a ton.
