Ask HN: Is there a safe /dev/null for e-mail addresses?

I hope this isn't a question out of place here. If so, my apologies in advance.

Is there an equivalent of /dev/null for e-mail addresses -- an address where, when you send it there, you can be assured that it goes into nothingness?

An additional (and perhaps essential) criteria would be it not being an address where a third party could redirect the "/dev/null"-iness of it into a normal, saving e-mail address.

This would not be on a mail server I would have any control or configuration over; in fact, I'd be using the address from Gmail.

I did recently purchase a domain name, so perhaps could do something along those lines, but I'm afraid I must admit to slight n00bishness when it comes to what one can do with mail redirection and URL redirection.

If it doesn't or can't exist, fair enough -- but thought I would inquire and I figured if it did exist, it'd be known by someone on here.

Thanks!
