Dumb question, but I need to ask. Do the users have a UserID [e-mail account] on the Exchange server? If so, you can use wwIPStuff and populate the e-mail ID, account password and e-mail server properties [don't remember exact name of properties], then call the SendMail method.

>I don't understand the first question though...regarding your statement that the customers need to install IIS. We were figuring that we would use the WestWind libs to send SMTP email via the customer's Mail Server (MS Exchange, for example). This worked fine for me here in the office...once I configured the Mail Server to allow for relaying of email messages from my IP address. What I was wondering...is how to work-around the issue of dynamically assigned IP addresses in regards to allowing/restricting relaying from the mail (smtp) server. Other than forcing the user to have a static IP Address for our application's workstation/server or having them provide a range of IP addresses.....I was hoping to know if there were another approach, while still using SMTP and WestWind.
