SEND SETTINGS
The Send Settings menu provides sub-menus that enable you to specify how messages will be delivered
when they are sent on to the user via RiskFilter E-mail.
DOMAIN-BASED DELIVERY
Domain-Based Delivery enables you to configure relay routing based on the domain of a recipient. It can
also help you to configure the routing delivery methods for e-mail by resolving e-mail servers via DNS or
forwarding to specified e-mail servers. If outgoing mail fails, RiskFilter will retry until a predefined limit is
reached. Routing delivery is configured in the Domain-Based Delivery screen.

Setting up the destination domains
To use Domain-based delivery, you need to add the domains of the destination servers to the Relay
Control screen in RiskFilter. You can add multiple servers. If more than one user-specified e-mail server is
listed, RiskFilter will control traffic automatically to ensure load balancing.
Delivering the messages
There are two ways of delivering a message:
• Resolve e-mail server via the following DNS server(s) – Send messages to the internal SMTP
server via a DNS server for resolution of host names.
• Forward e-mail to the following SMTP server(s) – Send messages to the internal SMTP server
directly so that it can deliver the message.
We recommend that you use Forward e-mail to the following SMTP server(s) for routing mail.
