Hi,

I am sending mail in asp.net, it shows nice message "Failure sending mail".

I used this code, please help me where it goes wrong.

C#:

 MailMessage mail = new MailMessage();
 mail.From = new MailAddress("Rupesh@RUPI-PC");
 mail.To.Add(new MailAddress("XXXXXX@gmail.com"));
 mail.Subject="Testing";
 mail.Body="testing the mail";
 SmtpClient client = new SmtpClient();
 client.host="localhost";
 client.port=25;

try
 {
     client.Send(mail);
     Response.Write("message sent successfully");
 }
 catch (Exception ex)
 {
     Response.Write(ex.Message);
 }

In IIS for SMTP E-mail the following details i provided
Email Address: Rupesh@RUPI-PC
Deliver e-mail to SMTP server: checked the Use localhost
Port=25
Authentication settings : selected Not Required

Please Suggest me whether i need to provide any further details in SMTP e-mail

Thank You
Rupesh

what you do is use catch (Exception ex)

If you want to see the underlaying SMTP-exception use:

catch (SmtpException exSmtp){Response.Write(exSmtp.Message); }

catch (Exception ex){Response.Write(ex.Message); }
To have better detail of the exception you can also use Response.Write(exSmtp.ToString());

Solution 2

C#

SmtpClient client = new SmtpClient();
client.host="localhost";
client.port=25;

Do you have an SMTP server running on your local host? I thought not.

MailAddress mailfrom = new MailAddress ( "frommail@gmail.com" );
           MailAddress mailto = new MailAddress ( "tomail@gmail.com" );
           MailMessage newmsg = new MailMessage ( mailfrom, mailto );

           newmsg.Subject = "Subject of Email";
           newmsg.Body = "Body(message) of email";

           ////For File Attachment, more file can also be attached

           Attachment att = new Attachment ( "G:\\code.txt" );
           newmsg.Attachments.Add ( att );

           SmtpClient smtps = new SmtpClient ( "smtp.gmail.com", 587 );
           smtps.UseDefaultCredentials = false;
           smtps.Credentials = new NetworkCredential ( "mail@gmail.com", "pwd" );
           smtps.EnableSsl = true;
           smtps.Send ( newmsg );
