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.
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 the parties that can send outbound mail through this
host to sources that you trust.
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
.
4
On the Outbound Mail Filtering - Local Relay panel, specify the internal host
to which this Scanner will relay outbound 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.
5
On the Outbound Mail Filtering - Nonlocal Relay panel, specify how you want
to relay outbound mail after filtering is complete.
You can use default MX lookup, select a host from the list, or define a new
host.
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.
For outbound mail addressed to a non-local domain, there is typically no relay
host to specify. If you choose Use default MX lookup, the appliance will use
Internet MX records to deliver the mail.
If you did not enable IM filtering, the Setup Summary panel is displayed.
See
“To review and finalize settings”
on page 44.
If you did enable IM filtering, continue completing the Add Scanner Wizard.
See
