He describes the flow of email for domains that have MX records
with the names of his MX hosts (when the primary MX is down, mail
queues on the secondary MX, from which it's sent to the primary).
In other words, he describes inbound email.
Outbound mail. on the other hand, is sent to the remote MX hosts
of remote destination domains. Those remote MX hosts are not the
MX hosts that he is talking about.
