When MailMessage.BodyFormat = MailFormat.Html, SmtpMail.Send throws exception

A

Aren Cambre

Why does SmtpMail.Send throw an exception if the MailMessage's
BodyFormat = MailFormat.Html? I've searched all over the place and
cannot find a solution anywhere. I am running this on Windows XP SP2,
and IIS's SMTP and WWW servers are installed.

Here is the error trace:

mailMessage.BodyFormat = MailFormat.Html;
mailMessage.Body = "aaaaa";
mailMessage.From = "(e-mail address removed)";

SmtpMail.SmtpServer.Insert(0, "www.smu.edu");
try
{
SmtpMail.Send(mailMessage);
}
catch (Exception ex)
{
Response.Write("<pre>");
Response.Write(ex.ToString());

while (ex.InnerException != null)
{
Response.Write("\n----------------------\n");
Response.Write("InnerException:\n" + ex.ToString());
ex = ex.InnerException;
}
Response.Write("</pre");
}

Any clues?

the error message is generic, any error in CDO causes it. does textmode
work? does html work if you send valid html?

Text mode worked fine.

This is very, very strange: I rebooted my computer, and HTML mode
works fine now. Maybe I've run into an intermittent bug?

I have same problem too. When I set textmode it works fine, but I set
htmlmode it cause 'cdo.message' exception. My development enviroments
are Windows XP (not sp2) & Visual Studio 2002. Is there anyone to help
it?

MailFormat.Html throws exception and not working

For this to get fixed you can add CDOSYS.dll as refernce to your asp.net application and build the solution and run it should work and will not throw exception.
