Uh, wait, that's the opposite of what I was asking. The envelope sender is
typically forged, so in bouncing a virus one would want to bounce to the MTA
that submitted the original message, and I was asking if any MTA's can do that.

Of course, a big problem with that is that many MTA's are one-way and wouldn't
accept the bounce on a subsequent connection.

Would it make sense to establish a new standard that requires that a MTA
listen on port 25 *for bounce messages only*?
