推荐答案

第一步，是否正确配置了在客户端上使用的电子邮件设置?

First step, are email settings correctly configured for use on the client?

您必须指定服务器和端口号:

You have to specify server and port number:

mSmtpClient.host = HostName;
mSmtpClient.port = PortNumber,

您可能还需要指定发件人电子邮件:

You may laso need to specify a From email:

MailMessage message = new MailMessage(FromEmail, ToEmail);

并且可能必须指定凭据:

and possibly have to specify Credentials:

mSmtpClient.Credentials = new System.Net.NetworkCredential(EmailUsername, EmailPassword);

可能还有SSL:

and possibly SSL:

mSmtpClient.EnableSsl = true;

我使用类似的代码连接到Hotmail，并且必须完成上述所有操作.代码如下所示:

I used similar code for connecting to Hotmail and had to do all of the above. The code looked like this:

public static void SendEmail(string Body, string UserEmail, string Subject)
    {
        SmtpClient client = new SmtpClient("smtp.live.com");
        MailMessage message = new MailMessage(Resources.Resource.OrganisationEmail, UserEmail);

        message.Body = Body;
        message.Subject = Resources.Resource.OrganisationName + Subject;

        client.Credentials = new System.Net.NetworkCredential(Resources.Resource.EmailUsername, Resources.Resource.EmailPassword);
        client.Port = 587;
        client.EnableSsl = true;
        client.Send(message);
    }

在这种情况下，我认为EmailUsername和OrganisationEmail相同，因为FromEmail必须与注册到Smpt Server帐户的电子邮件相同，但是使用Hotmail时，您的登录名就是您的电子邮件，因此它们是相同的.您的电子邮件密码就是您用来登录Hotmail的普通密码.

The EmailUsername and OrganisationEmail I believe were the same in this case as the FromEmail must be the same as the email registered to your Smpt Server Account but with Hotmail your login name is your email, thus they were the same. Your email password is just your normal password you use to login to Hotmail.

SmtpClient mSmtpClient = new SmtpClient()
mSmtpClient.Port = 25;
mSmtpClient.Host = "smtp.mail.yahoo.com";
mSmtpClient.Send(mMailMessage

用它来发送雅虎帐户

use it to send using yahoo account
