Fix a form on ASPX website

Hi For some reason, this form stopped working. It works when we download to our local computers, but on the server it shows an error. I have a form that needs the following job done to it. WE DO NOT REQUIRE A REBUILD, JUST FIX THE MAIL SENDING FUNCTION Developer said: I have a php script to send mail but now i want exact same asp script and it should work like my php script. OR Server Said: Change the PHP mail form to not send a Mail PHP Function, but send using the SMTP settings on the [login to view URL] file. The files are attached Thanks
