SPF doesn't know or care whether a domain is virtual or "real". So:

That's up to you. You can publish SPF records for any/all of the
domains that you control the DNS for (and your users can add SPF records
themselves if you do not control the DNS).

You don't need to publish SPF records for those, because SPF looks at
the return address of the E-mail and compares it to the IP that the
E-mail came from. You can only publish SPF records for domains, not
mailservers.
