发送电子邮件的问题 [英] problem with send email

问题描述

大家好

我想从我的网站发送电子邮件，我试过这段代码：

Hi all
I want send Email from my website , I tried this code :

MailMessage mm = new MailMessage();
mm.From = new MailAddress("[e-mail]");
mm.Subject = "Hello World ";
mm.Body = "Hello World";
mm.IsBodyHtml = true;
mm.To.Add(new MailAddress("[e-mail]"));
NetworkCredential nc = new NetworkCredential();
nc.UserName = "[e-mail]";
nc.Password = "MyPassword";
SmtpClient sc = new SmtpClient();
sc.Host = "smtp.gmail.com";
sc.EnableSsl = true;
sc.UseDefaultCredentials = true;
sc.Credentials = nc;
sc.Port = 587;
sc.Send(mm);
mm.Dispose(); mm = null;
nc = null;
sc.Dispose(); sc = null;

但是我得到了这个例子：

SMTP服务器需要安全连接或者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。了解更多信息

推荐答案

查看关于CP的类似讨论：

SMTP服务器需要安全连接或者客户端未经过身份验证。服务器响应为：5.5.1需要验证。 [ ^ ]

Check out similar discussion on CP:
The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.5.1 Authentication Required.[^]

mm.To.Add（toEmail @ hotmail.com，tomail @ yahoo.com ）;

mm.To.Add("[e-mail],[e-mail]");

转到您的邮件服务器并检查您的防火墙设置。然后，在Gmail中，将您从帐户设置获得的服务器地址添加到其安全客户端列表。

Go to your mail server and checke your firewall settings. Then, in gmail, add the server address that you got from your account settings, to their secured client list.
