How to set up the appliance
7 On the Inbound Mail Filtering - Local Relay panel, specify the internal host
to which this Scanner will relay inbound mail after filtering is complete.
You can select a host from the list or define a new host. A typical value is a
downstream mail server such as your corporate mail server.
You can also specify a port. If you check Enable MX lookup for this host, you
must specify a host name (not an IP address) for that server.

If you chose to filter inbound and outbound mail, the Outbound Mail Filtering
panel is displayed.
See "To specify outbound mail filtering settings"

To specify outbound mail filtering settings
1
On the Outbound Mail Filtering panel, choose the IP address to use for
outbound mail.
2
If desired, change the port specification for outbound mail.
In most cases this should be left as port 25.
3
On the Outbound Mail Filtering - Connections panel specify by IP address the
internal mail servers from which this Scanner will accept outbound mail.
Typically you would limit this to your corporate outbound mail server. It is
important to restrict to sources you trust the parties that can send outbound
mail through this host.
If you chose to filter only outbound mail, you will see the Outbound Mail
Filtering - Local Relay panel next. Proceed to step 4. If not, skip to step 5.
