Remote Mail Delivery
Always send all outbound email directly to the recipient's mail server
When this option is selected, SecurityGateway will use the normal SMTP delivery process to attempt to deliver each outbound message directly to the recipient's mail server—normal DNS lookups will be performed, MX records will be checked, and the like. This option is selected by default.
Always send every outbound email to the server specified below
Choose this option if you wish to send all outbound mail to another server, giving it the responsibility to deliver those messages.
Mail server:
Use this option to specify the mail server to which SecurityGateway will send all outbound messages, to let that server to handle their delivery. You can enter a host or IP address such as mail.example.com or 192.168.0.1.

Whenever any message, whether inbound or outbound, cannot be delivered due to a non-fatal error such as when the recipient's mail server is temporarily unavailable, these options govern how long SecurityGateway will continue trying to deliver the message before giving up and returning it to the sender.
During the first hour, retry delivery every: [xx] minutes (recommended: 5)
During the first hour after a message cannot be delivered, this is the interval that SecurityGateway will wait between making further delivery attempts. The default setting is 5 minutes.
After that, retry delivery every: [xx] minutes (recommended: 240)
After a message cannot be delivered for one hour, SecurityGateway will switch to this interval between further delivery attempts. The default setting is 240 minutes.
If a message is still undeliverable after [xx] days then suspend all delivery attempts and inform the sender that the message could not be delivered. (recommended: 5)
This is the number of days SecurityGateway will continue attempting to deliver a message before giving up. After that time it will cease delivery attempts and send a message to the sender stating that the message could not be delivered.
