How can I write a .Net web application, using the SmtpMail class (or anything else avaiable!) that successfully formats the body of an email, for display on Lotus Notes R6 and R4 (4.6) clients, with lots of special formatting - e.g., numbered and bulleted lists, differents fonts, colors, images, etc.? When I open one of these in R6, it's not too bad, but in R4 much formatting is lost. (I even lose alot of formatting when creating an email in R6 and sending it to an R4 client!) Are there any techniques, 3rd party componentes, or anything else that will help?? If not possible in .NET, how else might I create emails with special formatting and send them to R4 and R6 clients and have them both render correctly?
