HEEEELP!!! with sending the e-mails from the ASP.NET 2.0 application.

I need to be able to send an e-mail to the specified e-mail address from the application.
The following is the code snippet I am using to execute the task:
---------------------------------------------------------------------------------------
MailMessage Message = new MailMessage();
Message.IsBodyHtml = true;
Message.To.Add( new MailAddress(mToEmail)) ;
Message.From = new MailAddress(mFromEmail);
Message.Subject = mSubject;
Message.Body = mBody ;
SmtpClient smtp = new SmtpClient(mSmtpHost, mSmtpPort);



smtp.Send(Message);
---------------------------------------------------------------------------------------
I am using the following information to send an e-mail:

smtpHost ='mail.calinurseexpress.com'
smtpPort ='587'
----------------------------------------------------------------------------------------
The application is sending an e-mail in the synchronous mode. I am getting the following error:

System.Net.Mail.SmtpException: Failure sending mail. ---> System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: A socket operation was attempted to an unreachable host at System.Net.Sockets.Socket.DoConnect(EndPoint endPointSnapshot, SocketAddress socketAddress) at System.Net.Sockets.Socket.InternalConnect(EndPoint remoteEP) at System.Net.ServicePoint.ConnectSocketInternal(Boolean connectFailure, Socket s4, Socket s6, Socket& socket, IPAddress& address, ConnectSocketState state, IAsyncResult asyncResult, Int32 timeout, Exception& exception) --- End of inner exception stack trace --- at System.Net.ServicePoint.GetConnection(PooledStream PooledStream, Object owner, Boolean async, IPAddress& address, Socket& abortSocket, Socket& abortSocket6, Int32 timeout) at System.Net.PooledStream.Activate(Object owningObject, Boolean async, Int32 timeout, GeneralAsyncDelegate asyncCallback) at System.Net.PooledStream.Activate(Object owningObject, GeneralAsyncDelegate asyncCallback) at System.Net.ConnectionPool.GetConnection(Object owningObject, GeneralAsyncDelegate asyncCallback, Int32 creationTimeout) at System.Net.Mail.SmtpConnection.GetConnection(String host, Int32 port) at System.Net.Mail.SmtpTransport.GetConnection(String host, Int32 port) at System.Net.Mail.SmtpClient.GetConnection() at System.Net.Mail.SmtpClient.Send(MailMessage message) --- End of inner exception stack trace --- at System.Net.Mail.SmtpClient.Send(MailMessage message)




I also tried to use localhost:

SmtpClient smtp = new SmtpClient('localhost', mSmtpPort);

It did not work and I got the same error.

Do I need to provide the port infomation? If yes, is the port info correct? I am use 587 port.
What I am missing?

Lana, is there a user name and password that might need to be supplied here?


You can supply the SMTP information in the web.config file as follows, if you didn't know;
<system.net>
<mailSettings>
<smtp from="[email protected]">
<network port="25" host="mail.mysite.com" userName="[email protected]" password="password"/>
</mailSettings>
</system.net>
Default mail port is 25, which is not necessary to supply if it is 25.
Here is a B-Basic article on sending mail in ASP.NET 2.0;

Hope this helps!

This works for me... Not sure if it is the proper way to do it or not...


<mailSettings>
<smtp from="[email protected]">
<network host="localhost" port="25" defaultCredentials="true" />
</smtp>
</mailSettings>
