Utilities: Administration: Server: Server Settings: Network Settings: Relay Hosts
You can specify as many relay hosts as you like. Each entry must be separated by a carriage return. If you specify multiple relay hosts ListManager will automatically distribute the mail relay load between them. If you need to send a great deal of mail through a relay host setup, we recommend that you specify several relay hosts.
If the relay host is defined but unresponsive when ListManager is started or after changing this setting, you will see a warning on the console and ListManager will be unable to deliver mail.
Host IP address
The IP address of the relay host. A mail server must be listening on the IP address you specify.
Port
The port of the relay host receiving SMTP connections.
Maximum connections
The maximum number of connections to be made to this relay host. This setting may be used to prevent the relay host from being overwhelmed with ListManager connections.
NOTE If one or more relay hosts are defined, domain connection limits have no effect
