You can also control the default settings for unspecified domains.
Determining Which Interface is Used for Mail Delivery
Unless you specify the output interface via the
deliveryconfig
command or via
a message filter (
alt-src-host
), or through the use of a virtual gateway, the
output interface is selected by the AsyncOS routing table. Basically, selecting
“auto” means to let AsyncOS decide.

In greater detail: local addresses are identified by applying the interface netmask
to the interface IP address. Both of these are set via the Network > Interfaces page

are sent via the appropriate local interface.

If the destination is not local, packets are sent to the default router (set via the
Network > Routing page or with the
Network > Routing page or with the
setgateway
command). The IP address of the
default router is local. The output interface is determined by the rule for selecting
the output interface for local addresses. For example, AsyncOS chooses the most
specific IP address and netmask that include the default router's IP address.

The routing table is configured via the Network > Routing page (or via the

over the default route. A more specific route take precedence over a less specific

Default Delivery Limits
Each outbound destination domain has its own outbound queue. Therefore, each
domain has a separate set of concurrency limits as specified in the Destination
Controls table. Further, each unique domain not listed specifically in the
Destination Controls table uses another set of the “Default” limits as set in the
table.
