I created a form to use C# and ASP to let customers write back suggestions. When I run on local computer it works fine. After I move it to server, the error says "could not Access 'CDO.Message' object...message could not be sent to SMTP...". I tried to set the SMTPMail.SMTPServer=, also tried to re-register cdosys.dll, but not working. Anyone knows how to solve this problem? Thanks ahead!
