标签: smtpclient

这是我的代码

for(int i = 0; i < number ; i++)
{
MailAddress to = new MailAddress(iMail.to);
MailAddress from = new MailAddress(iMail.from, iMail.displayName);
string body = iMail.body;
string subject = iMail.sub;
oMail = new MailMessage(from, to);
oMail.Subject = subject;
oMail.Body = body;
oMail.IsBodyHtml = true;
oMail.Priority = MailPriority.Normal;
oMail.Sender = from;
s = new SmtpClient(smtpServer);
if (s != null)
{
 s.Send(oMail);
}
oMail.Dispose();
s = null;
}

这个循环发送超过60,000封电子邮件.但是我的问题是我在一些电子邮件中发送"发送邮件失败"了5000次,而且剩下的时间少了一些时间.我检查了所有那些错误,电子邮件有有效的电子邮件地址.不知道是什么问题.我真的需要帮助.

编辑:这是我的异常跟踪

错误 - 发送邮件失败.Inner Ex - System.IO.IOException:无法从传输连接中读取数据:net_io_connectionclosed.在System.Net.Mail.SmtpReplyReaderFactory.ProcessRead(字节[]缓冲液,的Int32偏移的Int32读,布尔的readLine)在System.Net.Mail.SmtpReplyReaderFactory.ReadLines(SmtpReplyReader呼叫者,布尔ONELINE)在System.Net.Mail.SmtpReplyReaderFactory .ReadLine(SmtpReplyReader呼叫者)在System.Net.Mail.CheckCommand.Send在System.Net在System.Net.Mail.MailCommand.Send(SmtpConnection康恩,字符串&响应)(康涅狄格州SmtpConnection,字节[]命令,从字符串).

我正在尝试从localhost发送邮件..

并且在这样做我有从不同的网站发送邮件的方法.. 但在这样做我感到困惑smtpClient.send()和smtpClient.SendAsync()..

我想知道他们是如何彼此不同的???

提前致谢..

SmtpClient发送方法返回void.有没有办法得到服务器响应？除非它抛出异常,我才假设它成功了吗？

我指的是...... http://msdn.microsoft.com/en-us/library/system.net.mail.smtpclient.aspx

我正在使用以下代码和平来使用godaddy托管发送邮件.

但它的投掷 System.Net.Mail.SmtpException: The operation has timed out.

protected void sendmail()
    {
        var fromAddress = "frommailid@site.com";
        // any address where the email will be sending
        var toAddress = "to@gmail.com";
        //Password of your gmail address
        const string fromPassword = "mypassword";
        // Passing the values and make a email formate to display
        string subject = "HI test mail ";
        string body = "From: pro@e-hotelspro.com";
        // smtp settings
        var smtp = new System.Net.Mail.SmtpClient();
        {
            //smtp.Host = "relay-hosting.secureserver.net";
            smtp.Host = "smtpout.secureserver.net";
            smtp.Port = 80; …

在Windows窗体项目中,我使用SmtpClient和MailMessage类来通过电子邮件发送信息.

Windows Phone 8是否有相同的功能？

尝试通过我的Web服务发送电子邮件时出错.我已尝试启用访问不太安全的应用程序,禁用两步验证并通过Web浏览器登录帐户.SO的解决方案都没有对我有用.我还是得到:

错误:System.Net.Mail.SmtpException:SMTP服务器需要安全连接或客户端未经过身份验证.服务器响应为:5.5.1需要身份验证.

我该怎么做才能解决这个问题？
