40 Installing Symantec Mail Security for SMTP Setting up Click Next and proceed with To specify outbound mail filtering settings . 2 On the Inbound Mail Filtering panel, choose the IP address to use for inbound mail. You can use the Test button to ensure that the mail server responds. The Test button scans the local network TCP table to see if an address/port is in use; any address that is not listed in this table is assumed to be unavailable. 3 If desired, change the port specification for inbound mail, and then click Next. 4 On the Inbound Mail Filtering - Connections panel, specify the mail servers from which this Scanner will accept inbound mail. You can choose All IP addresses or specify IP addresses or hostnames. A typical choice would be All IP addresses, thus allowing the Scanner to accept mail from any MTA on the Internet. If you specify one or more IP addresses, you must include the IP address of the Control Center so that Spam Quarantine and Suspect Virus Quarantine can release messages. After you add the first entry, the IP address of the Control Center is added automatically and selected. If you are using a different IP address for the Control Center, or have the Control Center and Scanner installed on different machines, you must add the new IP address and disable the one that was added automatically. Warning: If you are deploying this Scanner behind a gateway, and are specifying one or more IP addresses instead of All IP addresses, you must add the IP addresses of ALL upstream mail servers in use by your organization. Upstream mail servers that are not specified here may be classified as spam sources. 5 Click Next.
