We currently have all of our exchange servers located in our internal network. We let users send mail through them internally but we do not have a smtp server accessible from the outside. We would like to setup sendmail or equivalent so it will act as a SMTP server and authenticate the user through active directory. Does anyone have any suggestions or links on what would be the best to do and how to configure it? Thanks

Hi, Why you don't select the Front-end server (Exchange 2003) or Edge server (Exchange 2007) as your external SMTP server? Regarding sendmail, It's a pity that the limited knowlodage on this question, I didn't find the special value information that can direct you how to configure it. Thanks Allen
