To configure the Scanner for inbound mail filtering only
On the Scanner Role page, click Inbound mail filtering and click Next.
On the Inbound Mail Filtering page, click the drop-down list to select the IP address to use for inbound mail filtering.
In the Inbound mail SMTP port field, type the port, and then click Next.
On the Inbound Mail Filtering - Accepted Hosts page, to specify the IP addresses of the mail servers from which this Scanner should accept inbound mail, select one of the following options:
All IP addresses
You want your Scanner to accept mail from all sources or the Scanner is deployed at the Internet gateway.
For a Scanner that is deployed at the Internet gateway, Symantec recommends that you select this option to let the appliance accept mail from any MTA on the Internet.
Specific IP Addresses
You want to restrict the domains from which your Scanner should accept mail.
Type the IP addresses or host names.
If the Scanner is deployed behind one or more upstream mail servers, specify the upstream mail servers.
On the Inbound Mail Filtering - Mail Delivery page, do one of the following tasks:
In the Host name or IP address field, type the host where the Scanner should relay inbound mail after filtering is complete and in the Port field, type the port.
This server is typically a downstream mail server, such as your corporate mail server.
Check Enable MX Lookup for this host.
If you enable MX lookup, specify a host name instead of an IP address.
On the Inbound Mail Filtering - Non-local Mail Delivery page, select one of the following options to specify how you want to relay filtered mail:
Use default MX Lookup
You want to use MX Lookup to return the hosts for any domain.
Define new host
You want to specify a new host.
Type a host name or IP address and port in the required fields.
Symantec also recommends that you check Enable MX lookup for this host if you position the Scanner at the Internet gateway. If you choose this option, specify a host name (not an IP address) for that server.
Use an existing host
You want to use an existing host.
Select an existing host from the drop-down list.
If there is a separate gateway MTA between the Scanner and the Internet, provide that MTA's host name or IP address and port.
On the Local Domains page, check the addresses that you want in the Local Domains list. Include all domains for which you want to accept incoming mail.
To modify the list, do any of the following tasks:
To add an address
Type the address into the Domain or email address field for which to accept inbound mail field field and click Add.
For each domain address or email address that you add, you can also specify whether messages should be routed through a specific host and port. Add that information to the Optionally route to the following destination host and Port fields.
To delete an address
Check the address that you want to remove and click Delete.
To import a list of addresses
Click Import, and then navigate to an existing file.
To route messages according to the MX record for the specified host name
Check Enable MX Lookup.
If you enable MX lookup, you must specify a host name, not an IP address.
For example, enable MX lookup if you configure multiple downstream mail servers and use MX records for email load balancing.
On the Setup Summary page, review your settings and select one of the following options:
You are satisfied with the settings and want to save them.
You want to modify your settings. Go back and revise your settings.
You want to cancel your changes without saving them.
