Relay Host

Relay all outbound mail through this mail host rather than doing regular direct delivery.

Lyris strongly recommends that you not use a relay host, because ListManager has been optimized to send mail directly to the Internet. Using a relay host may delay mail delivery, and result in inaccurate delivery reports. Some bounced mail may also be returned to the relay host instead of ListManager, preventing ListManager from handling error mail correctly.

However, some environments need outbound mail to be relayed through a specific host. For instance, your organization might employ a TCP/IP firewall that prevents ListManager from directly delivering mail. In such a case, each application behind the firewall must use a Relay Host to communicate with the outside.

A mail server must be listening on the port of the TCP/IP address that you specify. For this setting, you specify an IP address/port combination (not a host name).

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.
