使用C＃发送电子邮件（Cpanel Hosting）

Question

我买了一个cPanel主机，SMTP服务器信息是：

这是我的代码：

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);
    }
}

当我运行我的代码并在1或2分钟后点击发送按钮时，会出现：

  

其他信息：发送邮件失败。

我做错了什么？

Answer 1

我觉得你错过了什么，试试这个：

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);

您似乎无法通过端口465访问Yahoo地址，请检查此地址是否可以首先访问，因为它似乎是网络问题。
