How can I block someone's e-mail address and have the mail bounce
back
to them. Thanks.

Make a message rule to Delete it from server. Don't attempt to
bounce.
If it is a fake address, your bounce will end up in a loop being
bounced
back to you, and if the address is real, then all you accomplished
was
to verify your address is valid.

Those fake bounces impersonate your ISP's
'MAILER-DAEMON', and that generally is a violation of the TOS of your ISP.

Why should anyone suppose this true?

I have a nasty habit of reporting MailWasher bounces as abuse to the ISP
where
they originate. The ISP may just ignore my complaints; but who knows? I
also
put the source IP address in my mail server ACL, which means that future
fake bounces are rejected by my server. Your server, which is used by
MailWasher to send those fake bounces, will then bounce the MW bounce
right
back at the sender.

Perhaps N. Miller employs a nonstandard configuration.
In several years of bouncing bogus emails via Mailwasher
I do not recall a single instance of "a loop being bounced
back to you." (Mailwasher can be configured to bounce
from the ISP server: no logic suggests how this can
confirm "the address is real.")
