sending email
 

Hi all

I have been trying to send email from my asp.net website using c#. the code runs without any errors, but when i click the send button i get this error.

/*System.Net.Mail.SmtpException: Failure sending mail.---> System.Net.WebException: Unable to connect to remote server -->System.net.sockets.socketException: a connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond
at System.Net.Sockets.Socket.EndConnect(IAsyscResult asyncResult)*/
------------------------------------------------------------------

I heard that McAffee OAS blocks emails from going out but i have disabled it in my computer. Can you please help in eliminating this error.

Check, if your mail client is created in this way ?

System.Net.Mail.SmtpClient mailClient = new SmtpClient("your.smtp.server", 25);
System.Net.NetworkCredential nc = new System.Net.NetworkCredential("YourLogin", "YourPassword");
mailClient.Credentials = nc;

And also check address of your SMTP server, login and password, if they are all correct. Or there may be also problems at server side.

here is the code i used

System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage();

message.To.Add(emailAddTextBox.Text);

message.Subject = "Testing";

message.From = new System.Net.Mail.MailAddress("myusername@gmail.com");

message.Body = "Just Testing";

 

System.Net.Mail.SmtpClient smtp = new System.Net.Mail.SmtpClient("smtp.gmail.com",25);



 

SmtpClient client = new SmtpClient();

smtp.Credentials = new System.Net.NetworkCredential("myusername", "mypassword");

smtp.Port = 587; 

smtp.Host = "smtp.gmail.com";

smtp.EnableSsl = true;



 

try

{

smtp.Send(message);

}

catch (Exception exmail)

{

flightNameLabel.Text = "The email cannot be sent" + exmail.ToString();

}

But are you sure that smtp.Port must be 587 but not 25 ? Usually SMTP port is 25 (that is why I have prescribed 25 in SmtpClient constructor). If it is 587, then replace 25 into 587 in that line. Try also with smtp.EnableSsi = false.
