Are you sure about that Arne ?

There's a difference between routing email within a large organisation
and dropping suspect mail with a SMTP reject while it is being received
by the machines listed in the MX records for the receiving domain.

If it gets dropped at the MX boundary between the sending and receiving
organisations, surely the email sender gets to find out directly because
of the SMTP reject.
