You may have to... and use your own disposable-address as the exclusive sender; after you're done you'll need to remove the exclusive sender

Q. Is there a way to give an address that allows the initial sender to send an unlimited number of messages, but eats mail from anyone else ('exclusive sender')?
A. <snip>
Also, if it's the "to" address that is unique for a particular mailing list you want to use, that will work just as well here (just don't put the disposable address itself here, of course, since that would have the effect of allowing an unlimited number of messages from anyone).
