我试图弄清楚当 smtp.auth 属性设置为 false 时为什么会收到 AuthenticationFailedException。从调试日志中，它仍然尝试验证登录。我已经针对在服务器上运行的 localhost smtp 服务器测试了代码，该服务器运行良好，但在发送到第 3 方服务器时失败。

我已经尝试通过 telnet 手动发送电子邮件，而不使用身份验证，并且电子邮件是通过 3rd 方 smtp 服务器成功发送的，所以我不相信这是服务器的限制。

我正在使用 javamail-1.4.7。

调试输出

我不明白为什么即使它被禁用它也试图进行身份验证

请注意，即使 mail.smtp.auth 默认为 false，我尝试明确声明它，但仍然没有帮助。

它正在进行身份验证，因为您正在使用用户名和密码调用 connect 方法。

这有点令人困惑，但是将 mail.smtp.auth 设置为 true 的原因是，如果您在没有用户名和密码的情况下调用 connect 方法，则强制它回调您的 Authenticator。在这种情况下，将其设置为 false 可避免回调。但是，如果您明确地传递用户名和密码，就像您正在做的那样，它假定您是故意这样做的，并且您想使用它们来进行身份验证。

你可以更好地使用 SMTPTransport

让它像

SMTPTransport m_transport；

if(mail.smtp.auth is set to false)
{
    m_transport.connect(new Socket(getSMTPHost, getSMTPPort));
)else{
    m_transport.connect(SMTPHost,SMTPPort,AuthUserAddress,Password);
}

要使用 Socket，您需要导入 java.net.Socket
