Google Outbound Services Configuration Guide - Manual (Page 109)

IBM Lotus Domino (Smarthost Method) 117
Set Up Smarthost
After you have set up reinjection and registered the IP of your outbound mail
server in the Administration Console, set the
relayhost parameter to route mail to
the email security system. This will set Outbound Services as the smarthost.
Domino stops processing queued messages when delivery of a message fails or
the relay host is perceived to be down or unreachable. Setting the Retry Interval to
a lower value allows the queue to start moving again more quickly.

Test Outbound Mail
Check the mail queues of the mail server.
1. Check the mail queues of the mail server to look for items with a retry state
which could indicate outbound mail delays.
2. Send a message from a mail client inside your network to an outside address.
You should see a line in the header email which indicates being received and
delivered by
exprodNobM.obsmtp.com , where N and M are numbers.

outside email address to an address on your service.
