Some long-time Postini customers may be using an out-of-date address format for the Postini outbound gateways.  If you notice an interruption in outbound mailflow and you use a smarthost address such as "outbound1.obsmtp.com" or "outbound3.obsmtp.com", please update your mail server configuration to use the current correct addresses:

System 5

System 6

System 7

System 8
