Hi,

I have been developing a site and have set up a form to email:

System.Web.Mail.MailMessage message = new System.Web.Mail.MailMessage();
            message.From = from;
            message.To = to;
            message.Subject = subject;
            message.Body = body;
            message.BodyFormat = System.Web.Mail.MailFormat.Html;

            System.Web.Mail.SmtpMail.Send(message);

This works fine on my local machine but I cannot get the email sent on the server - Here is the error message I'm getting:

The "SendUsing" configuration value is invalid.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Runtime.InteropServices.COMException: The "SendUsing" configuration value is invalid.

[COMException (0x80040220): The "SendUsing" configuration value is invalid.
]

Anyone have any ideas?

Thanks in advance

Jay

Does mail sent through the server need CDO authentication?

Hi there,

You may need to set the SMTP server explicitly. I believe it defaults to localhost (that's why it works on your local machine). Apparently, the server your page runs on does not have an SMTP server installed, so it can't send the mail using localhost.

Try this:or in your case since you're not using a using statement (no pun intended):This will force the ASP page to send the e-mail to the smtp.YourProvider.com server.

Hi ally

i also got above that type of error
The "SendUsing" configuration value is invalid.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.


I tried below type of coding , but not use

SmtpMail.SmtpServer = "smtp.YourProvider.com";
SmtpMail.Send(objMail);

(or)

SmtpMail.SmtpServer = "IP address";
SmtpMail.Send(objMail);

(or)

SmtpMail.SmtpServer = "localhost";
SmtpMail.Send(objMail);

(or)

SmtpMail.SmtpServer = "the_machine_name";
SmtpMail.Send(objMail);

nothing happen

not use above coding

give some others solution

10x in @vance

I don't want to be funny, but did you replace smtp.YourProvider.com with an actual valid SMTP server provided by your ISP??
