I have an application in which users can email .asp pages via the "File &#124 Send &#124 Page by E-Mail" menu option using Outlook 2000. This works fine in almost all circumstances except one: when it is run from the IIS server machine on which the application resides, i.e. server and client are the same machine. In this circumstance, Outlook 2000 sometimes wants to send the page as a .txt instead of a .htm. The contents of the .txt is the source, i.e. what you see when you select "View &#124 Source". Any ideas?
