Outgoing Smarthost Setup

If you use a dynamic IP or you are unable to get the proper PTR records set up then you might need to consider using a smarthost. In this case all outgoing messages would be sent to CSEG mailserver and the actual recipient would be contacted by CSEG mailserver itself. Please note that for smarthost option, email user authorization should be handled on your side, either by IP address or by using SMTP AUTH.

A smarthost allows an SMTP server to route email to an intermediate mail server. This can ease mail server management.

This enables you to route messages over a connection that may be more direct or less costly than other routes. The smart host is similar to the route domain option for remote domains. The difference is that, after a smart host is designated, all outgoing messages are routed to that server. With a route domain, only messages for the remote domain are routed to a specific server. If you set up a smart host, you can still designate a different route for a remote domain. The route domain setting overrides the smart host setting.

You can route all incoming / outgoing messages for remote domains through a smarthost instead of sending them directly to the domain to reduce e-mail spam from the recipient’s mail server via the default SMTP port.

There are two service servers, one in the US and other in the EU. You should provide the hostname of the CSEG server that you are using as your preferred CSEG service domain. The CSEG service URLs are:
