smtp2 doesn't deliver the mail to an IMAP mail storage daemon. Instead, it spools it and waits.... The MX backup machine can be in a different country. When the primary MX comes back up, the MX backup machine will relay spooled mail to it over the Internet via SMTP. That is a benefit of different priority MX records within a DNS zone.
