It's also worth considering open relays - if you're receiving messages
from an open relay it may be a Bad Thing to reject them since the open
relay may well generate a bounce to the (spoofed) sender in response to
the rejection. (Open relays are, by definition, incorrectly configured).
Yes, but you aren't responsible for that. If you generate the bounce, then
you're responsible for collateral spam. If the open relay generates
collateral spam, then they're responsible.
