@jwz And presumably a decent proportion of "everything else" has a Google or Microsoft MX record.
@jamesh Various local EDUs make a strong showing in there, but yes, presumably.

@jwz it looks like all four of the big universities in my city are on Office 365 mail these days.

That's quite a change from back when I was in uni, where each individual department ran their own independent mail systems.

@jamesh @jwz Back when rocks were warm, I adminned a mail server which had a public address of the form department.site.company.tld.
This was a bit of a pain when people moved departments, so they did eventually set up simple company.tld mailboxes too, and people decided which to forward where.
