Register Your IP in the Administration Console
After you have set up reinjection, register the IP address of your outbound mail
server in the Administration Console. Do not change your smarthost until your IP
address is registered in Outbound Servers.
For instructions on how to register your IP in the Administration Console, see
“Register Your IP in the Administration Console” on page 15.
Set Up Smarthost
In order to send email on an edge transport server it is required to configure a
send connector. Edge Transport servers subscribed to an Exchange organization
are pre-configured with the necessary elements to send and receive mail from the
internet. Configuring Postini outbound services will change the default setup of
these connectors.
Because send connectors are organization wide configurations and part of the
synchronization process editing them takes place on the hub transport server.
Send connectors are created and edited in the Exchange Management Console
by doing the following from any hub transport server:
1. Choose Organization Configuration -> Hub Transport
2. Click Send Connectors.
3. Double-click the connector named “EdgeSync – [your site] to Internet”,
where [your site] is the name of your site.
4. On the Address Space tab verify that the “*” domain has been added.
