Dear all, I have an exchage server 2003 installed on a server that hosts ISA server and also it has two network addaters one for internal email and the other for external email. when I have used the Internet connection wizerd to create a connector for the internet to send messages using a smarthost (third party SMPT mailserver) it give me a choice to have two smtp servers one for the internal network and one for the external. after I have complete the wizred and I have my two smtp servers plus the connector. I couldn't send emails to the internet. can you tell me where i can find a detialed information about configuring exchange to connect to the internet using a smarthost connection. Best Regards. Hashem
