Yes. But David said that Verisign forwards to your designated server,
rather than operating a mail store.

So [email protected] may forward to Hotmail while [email protected] may forward
to gmail., and [email protected] may forward somewhere else.

Sending on behalf of [email protected] requires a hosting service that allows
you to send using a From domsin that does not match the Mail From domain.

Then any authentication for one account becomes an authorization to
impersonate the other accounts, but a complete list of all possible sources
would cause PERMERROR for SPF even if it could be built.

Verisign wants to be the S/MiME solution for any mailbox provider account,
not rhe competition for them.
