Look in Postfix LOGS. If the second instance is not up, then fix that. http://www.postfix.org/DEBUG_README.html#logging Look at your TCP ports. If the second smtp port is not open, fix that. # lsof -i Look at your firewall rules. If it does not allow access to the second instance, fix that. And so on. Wietse
