Not sure about that, but you can block some of the *types* of messages
that will be sent to certain addresses (or from certain addresses).  So,
instead of when they'd normally get a denial message from you, they'll
get no response from you, and *their* side will report as being unable
to do something.

But, to be honest, I've never believed the paranoia behind the reasons
commonly offered for blocking pings.

Don't send private replies to my address, the mailbox is ignored.  I
read messages from the public lists.
