also, (or: alternatively?) one that can't be/won't be blocked by the centralized services' spam filters. The biggest hurdle to running your own email server nowadays isn't the online time or the data volume or anything; it's that the existing institutions don't recognize you as part of the institutional club and block your messages...
btw, Germany did this a decade ago: giving everyone an email account with the national mail service, as an "official email." I honestly don't know anyone here who uses it.

How common is this if you’ve setup DKIM, SPF, etc.? I’ve only heard about problems in that context where someone hadn’t done the basics or was trying to send from shared IPs and hit some spammer’s past reputation.
Presumably it would be tied to an individual's identity which would make it easy to identify who was sending the email and fine them using existing anti-spam laws.
