我正在尝试使用 C# 在我的 Yahoo 帐户上检索邮件。我测试了 OpenPop 来做到这一点，我写的是

Pop3Client objClient = new Pop3Client();
objClient.Connect("pop.mail.yahoo.com", 995, true);
objClient.Authenticate("username","pass",AuthenticationMethod.UsernameAndPassword);
int msgCount = objClient.GetMessageCount();
MessageBox.Show(msgCount.ToString());

服务器始终不接受用户凭据但我确定凭据正常的问题。

我用我的 gmail 帐户尝试了相同的代码，一切正常，雅虎希望我设置它吗？

为了通过电子邮件程序访问 Yahoo 邮件，您需要成为 Yahoo Mail Plus 订阅者。

1. Sign in to Yahoo Mail.
2. Move your cursor over the gear icon (Gear Icon) and select Mail Options.
3. Select POP & Forwarding.
- The "Access your Yahoo Mail elsewhere" option displays.
4. Select the radio button next to Access Yahoo Mail via POP.
5. Click Save.

试试下面的代码：

try
 {
    if (pop3Client.Connected)
        pop3Client.Disconnect();

    pop3Client.Connect("pop.mail.yahoo.com", 995, true);
    pop3Client.Authenticate("your@yahoo.com", "yourpassword");
    int count = pop3Client.GetMessageCount();
}
catch (InvalidLoginException)
{
   //MessageBox.Show(this, "The server did not accept the user credentials!", "POP3 Server Authentication");
}
catch (PopServerNotFoundException)
{
   //MessageBox.Show(this, "The server could not be found", "POP3 Retrieval");
}
catch (PopServerLockedException)
{
   //MessageBox.Show(this, "The mailbox is locked. It might be in use or under maintenance. Are you connected elsewhere?", "POP3 Account Locked");
}
catch (LoginDelayException)
{
   //MessageBox.Show(this, "Login not allowed. Server enforces delay between logins. Have you connected recently?", "POP3 Account Login Delay");
}
catch (Exception e)
{
   //MessageBox.Show(this, "Error occurred retrieving mail. " + e.Message, "POP3 Retrieval");
}
