I am using CDO from my VB code to send automated emails. I did not configure the default SMTP server at alll, but it works fine for emails on my intranet. Now I want to be able to send email to "yahoo.com" or any other email address. Please let me know how to configure the IIS SMTP to do that. I added "smtp.yahoo.com" to the domain name, but it still doesnt send out the emails.They get stuck in the queue. If possible, please point me to a resource on how to configure this server.
