Problems sending emails

[Srinivas]

Hi,

I am using ASP.NET SmtpMail to send email using the following code

public void SendEmail(string From, string To, string Subject, StringBuilder
Message, string Attachment, string mailFormat)
{
MailMessage mailMessage = new MailMessage ();
mailMessage.From = From;
mailMessage.To = To;
mailMessage.Subject = Subject;
mailMessage.Body = Message.ToString ();

if(mailFormat == "T")
{
mailMessage.BodyFormat = MailFormat.Text;
}
else if(mailFormat == "H")
{
mailMessage.BodyFormat = MailFormat.Html;
}

SmtpMail.SmtpServer = "10.0.0.1";
SmtpMail.Send (mailMessage);
}

This code executes fine without error. But the email goes and sits in the
"C:\Inetpub\mailroot\Queue" folder.
SMTP service is running and cdosys.dll and cdonts.dll are installed.

My computer is connected to the internet through a Speedtouch 545 ADSL
router. I got the "10.0.0.1" by doing the ipconfig at command prompt.

Can anyone please guide me in the right direction.

Thanks,

Srinivas

Well, you've got two potential problems here:
1) Is your C# code correct?
2) Is your SMTP server correctly configured?

I strongly suspect that the second one is the problem, but fortunately
you can test it in isolation - just tell your normal mail client to use
10.0.0.1 as the SMTP server, send a mail, and see what happens. I
suspect the same thing will happen as from your C# code. At that point
you need to look at your SMTP server logs etc. Once you've got your
SMTP server definitely working, try the C# code again - if that fails,
post here again
