發送電子郵件C＃（cPanel主機）

Question

我已經買了的cPanel主機和SMTP服務器信息是：

這是我的代碼：

string smtpAddress = "mandane.hostcream.com"; 
int portNumber = 465; 
bool enableSSL = true; 
string emailFrom = "mahabadi@exirsec.ir"; 
string password = Authenitication.PassWord; 
string emailTo = To.Text; 
string subject = Subject.Text; 
string body = Body.Text; 

using (MailMessage mail = new MailMessage()) 
{ 
    mail.From = new MailAddress(emailFrom); 
    mail.To.Add(emailTo); 
    mail.Subject = subject; 
    mail.Body = body; 
    mail.IsBodyHtml = true; 

    using (SmtpClient smtp = new SmtpClient(smtpAddress, portNumber)) 
    { 
     smtp.Credentials = new NetworkCredential(emailFrom, password); 
     smtp.EnableSsl = enableSSL; 
     smtp.Send(mail); 
    } 
} 

當我運行我的代碼並在出現1或2分鐘後點擊發送按鈕：

附加信息：發送郵件失敗。

我在做什麼錯？

Answer 1

我想你錯過了什麼，試試這個：

SmtpClient smtpClient = new SmtpClient(); 
NetworkCredential smtpCredentials = new NetworkCredential("email from","password"); 

MailMessage message = new MailMessage(); 
MailAddress fromAddress = new MailAddress("email from"); 
MailAddress toAddress = new MailAddress("email to"); 

smtpClient.Host = "smpt host address"; 
smtpClient.Port = your_port; 
smtpClient.EnableSsl = true; 
smtpClient.UseDefaultCredentials = false; 
smtpClient.Credentials = smtpCredentials; 
smtpClient.DeliveryMethod = SmtpDeliveryMethod.Network; 
smtpClient.Timeout = 20000; 

message.From = fromAddress; 
message.To.Add(toAddress); 
message.IsBodyHtml = false; 
message.Subject = "example"; 
message.Body = "example"; 

smtpClient.Send(message);

看起來您無法到達端口465的雅虎地址，請檢查此地址是否首先到達，因爲它似乎是網絡問題。
