Routing and Session Management

You can define individual encryption settings for each domain, then validate your settings by initiating a test connection to a valid domain.

To configure outbound routing and session management parameters:

Manage >> Outbound IPs >> {Outbound IP}

1.

Select the Limit message size checkbox.

2.

Enter the maximum size for an individual email message. Valid options are 1 through 100. Messages larger than the defined maximum are rejected by the system. Note that if an attachment is larger than 10MB, the bounce message notification does not include the attachment, it only includes the message headers.

3.

Enter the number of hours to spool mail before it bounces back to the sender (default is 1), in case of server failure. From 1 through 320 hours.

4.

If you want a copy of every delivered message sent to a particular email address, enter the address in Send a copy of every delivered message to.

5.

If you want to keep copies of messages, check Keep a copy of messages delivered to the Mail Gateway.

6.

In the Routing area, do the following:

•

Select Use external DNS resolution in the unlikely case that the system is unable to deliver mail to multiple domains and you don't want to create delivery exceptions.

•

Select MX to use MX routing, or select the second radio button and enter the host name or IP address in the text box.

7.

To configure delivery exceptions, click the add icon next to Add Delivery Exception and enter the domain, routing, and encryption. Click OK to add the domain. For details, see Domain-Specific Delivery Exceptions.

8.

If you want to send a test message from the product to validate the settings, enter a valid mailbox name in the Test Connection text box and click Test.
