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.
