Re: Error-While sending Mail - C# Discussion Boards

18-Nov-07 22:40

Hi, I designed a windows applciation by reading mail id's from text file and sending mails. But after sending more than 900 mails i am getting this error.

Exception Occured System.Net.Mail.SmtpException: Failure sending mail. ---> System.IO.IOException: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. ---> System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host

Can any one help reg this error...
I used the code as follows

MailAddress SendFrom = new MailAddress(txtFromAddr.Text);
SmtpClient objSmtpClient = new SmtpClient();
objSmtpClient.Host = "mail.domain.com";
objSmtpClient.Credentials = new System.Net.NetworkCredential("uname", "pwd");
while (!strdata.EndOfStream)
{
_mailId = Convert.ToString(strdata.ReadLine());
if (_mailId != "")
{
MailAddress SendTo = new MailAddress(_mailId);
MailMessage objMailMessage = new MailMessage(SendFrom, SendTo);
objMailMessage.Subject = Convert.ToString(txtSubject.Text);
objMailMessage.Body = Convert.ToString(webBrowser1.DocumentText);
objMailMessage.IsBodyHtml = true;
objSmtpClient.Send(objMailMessage);
}
}

This may be your problem. I rather imagine your ISP wwill have terminated the SMTP connection after you sending so many emails. You should check with them about their bulk email policy.

You'll need to check with whoever runs the SMTP server that you are using to send your email. Many ISPs have rules about the number of emails you can send at a time to prevent spamming. I assume you have the permission of the people you are emailing?

When i run the Email application, automatically the to-address is repeating.
ie.

TO: satish.g@techgene.com; kiran@techgene.com; madhu@techgene.com;
the above line is for one mail.
And for next mail

TO: satish.g@techgene.com; kiran@techgene.com; madhu@techgene.com; suchi@techgene.com

like this for mail to mail.. the toaddress is repeating.

But when i debug this, there is no loops to get this, and also when sending mail
there is only one id in to-address?

any idea ? what's the reason by coming like this?
there is no loop to come like this.
u can see the code in above posting

Hi, Please see the code below.
I am reading mailid's from text file. In each line there is only one mailID.
so "_mailid" contains only 1 id.
now can u suggest how to put cc

MailAddress SendFrom = new MailAddress(txtFromAddr.Text);
SmtpClient objSmtpClient = new SmtpClient();
objSmtpClient.Host = "mail.domain.com";
objSmtpClient.Credentials = new System.Net.NetworkCredential("uname", "pwd");
while (!strdata.EndOfStream)
{
_mailId = Convert.ToString(strdata.ReadLine());
if (_mailId != "")
{
MailAddress SendTo = new MailAddress(_mailId);
MailMessage objMailMessage = new MailMessage(SendFrom, SendTo);
objMailMessage.Subject = Convert.ToString(txtSubject.Text);
objMailMessage.Body = Convert.ToString(webBrowser1.DocumentText);
objMailMessage.IsBodyHtml = true;
objSmtpClient.Send(objMailMessage);
}
}

without doing this. Just create mailmessage object.

MailMessage objMailMessage = new MailMessage();<br />
objMailMessage.To = "toUser's email ID";<br />
objMailMessage.Subject = Convert.ToString(txtSubject.Text);<br />
objMailMessage.Body = Convert.ToString(webBrowser1.DocumentText);<br />
objMailMessage.IsBodyHtml = true;<br />
<br />
SmtpClient objSmtpClient = new SmtpClient();<br />
objSmtpClient.Host = "mail.domain.com";<br />
objSmtpClient.Credentials = new System.Net.NetworkCredential("uname", "pwd");<br />
<br />
objSmtpClient.Send(objMailMessage);<br />

Just try this. If you are getting error then u must have to chekc for smtp setting of server.

for your kind info it's not a Data Grid, it's like a table which u can see while designing ur windows form and can place controls accordingly.
Do have a look at that...

Using .NET 2.0 from VS2003 editor ?

I have .NET framework 2.0 installed on my machine. But I don't have VS2005. I am using VS2003. Is there anyway to access the .NET 2.0 libraries using VS2003 ?

AKAIK, you can only write code against v1.1 of the framework in VS2003.

You need to either upgrade to VS2005, or use a 3rd party IDE like SharpDevelop.

Thanks. So what about .NET 3.0 ? If I have VS2005 installed, can I use .NET 3.0 classes ? I guess we can

Yes, you can use dot net 3 in VS2005, but not in VS2003.

This link[^] explains how to update VS2005 to access .NET 3.0 functionality.

I believe that in VS2008, it will be possible to build your code against a specific version of the framework.

Your right but it's limited to 2.0, 3.0 and 3.5, you wont be able to do 1.0 or 1.1.
