No. That sums it up perfectly.

No. You can, however, specify a whole domain instead of a specific address. E.g. instead of "Exclusive1@Sender.com" just put "Sender.com". You can also put the disposable address itself in the exclusive sender field, in which case the address will never shut off, no matter who is sending to that address. (Careful with that, though... if someone sends you a couple hundred messages in one day, you're going to feel it.)
You can also use a domain as a trusted sender.

No. You can't specify more than one exclusive sender.
Real programmers don't comment their code. It was hard to write; it should be hard to understand.
