Hi

    I a developing on a Windows 2003 Server environment with MS Exchange
2003 installed, using the following code i am able to send e-mail message to
Administra***@myserver.com but not to any internet address eg
ba***@gmail.com

    try
    {
       MailMessage Message = new MailMessage();
       Message.To = "ba***@gmail.com";
       Message.From = "administra***@myserver.com";
       Message.Subject = "Testing";
       Message.Body = "Some message";

       try
       {
           SmtpMail.SmtpServer = "MYSERVER";
           SmtpMail.Send(Message);
       }
       catch(System.Web.HttpException ehttp)
       {
       }

TIA

Hi Barry,

maybe the problem is, that this example
works without authentication ? I think you
should use a smtp implementation which support
authentication. On Codeproject.com you
will find a smtp mailer class with authentication
and attachement support ;) Also you should
install a trace programm like YATT to trace
the communication between your app and the
smtp server.
