It can. Just give your users POP logins of the form
[email protected]

Don't give them each their own pop3 server, just give them distinct
accounts per virtual domain on the same pop3 server.

ftp can't be name-virtual-hosted. It is also such a wretched
protocol that it urgently needs to be retired in all settings for
all purposes.

The only real excuse I'd argue for keeping IP virtual hosts is
https --- but as there's no chance of a secure replacement for HTTP
that works with name virtual hosts getting deployed any time soon,
and as the last legal barrier to universal deployment of https
is falling in just a month, I think ARIN has picked a remarkably
unfortunate time to launch this crusade. If they'd done it a couple
of years ago, maybe it would have helped to nudge some of the folks
who just never bothered to learn how to configure name virtual
hosts into shifting a bit, and possibly this could have helped
provide motivation for designing something better than the current
https, like e.g. a TLS negotiation within http, and maybe we could
be approaching the point where such an improved client might be
widely-enough available. But now there's no helping it, IP virtual
hosts are the primary webserving product for the next bit of a while
