injection server to relay mail traffic through them.

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.
Increase Server Timeouts
To improve reliability of delivery, be sure to increase the timeouts of your outbound
mail server. This provides Outbound Services with some flexibility to handle slow
receiving mail servers.
