  • Hi,

    The operation has timed out.

    evertime I try to send an email

    I am hosting with dreamhost.

    What could be the issue please?

    mail_message.From = new MailAddress("noreply-employee-request@mybluefile.com", "BlueFile");
    mail_message.To.Add(new MailAddress(Convert.ToString(sql_command.Parameters["param_employee_email"].Value), Convert.ToString(sql_command.Parameters["param_employee_name"].Value)));
    email_body = new StringBuilder();
    email_body.Append("<i>Please do not reply to this message. Replies to this message are routed to an unmonitored mailbox.</i>");
    email_body.Append("My message here......";
    email_body.Append("Best Regards,");
    mail_message.Subject = cboCategory.Text + " Request is Completed";
    mail_message.IsBodyHtml = true;

  • Hi Jassim,

    This problem occurs when you're not able to connect to the SMTP server, hence the timeout message. There are several possibilities why this problem has occurred:

    • Wrong SMTP address
    • SMTP rejected
    • SMTP server is offline
    • Port setting
    • SSL configuration

    You should try setting the credentials, or the server is down or is not replying at all - these are the errors that might generate this problem. Please ensure that the above points are correct.

    I also tested with your code,  use hotmail instead and change port to 587, the code works fine.

    Best regards,
