Delivering email
Use this section to specify how the appliance tries to deliver email, based on the domain part of the
recipient's address. In a
To
field, the domain part of an address such as aaa@example.com is
example.com.
Using the recipient's domain, the appliance uses the following logic to decide how it will deliver
messages:
• If the recipient's domain matches those listed in
Known Domains and relay hosts
, it uses those relays to
deliver the message.
• If the recipient's domain does not match those listed in
Known Domains and relay hosts
, it can be
configured to use an MX record lookup to deliver using DNS. If no MX records are available, it
attempts to make the delivery using an A record lookup. MX delivery is attempted to hosts in the
order of priority that is returned by the DNS server.
• If it cannot deliver using one of the previous methods, it uses fallback relays to make the delivery
(providing the recipient's domain matches those listed in the
Fallback relays
field).
