It is a rarity to see any organization that self hosts email or uses a domestic provider any more. It is all foreign controlled now (specifically Microsoft). It should be examined by regulators everywhere both as a monopoly and a sovereign threat. The move to US services started long before the current political situation and will still be a threat to sovereignty long after the current US exec is gone. The frustrating thing is email services like many cloud services are highly substitutable and can easily be built on open source infrastructure.
