我想弄清楚为什么当smtp.auth属性设置为false时我收到AuthenticationFailedException。从调试日志中，它仍然尝试授权登录。我已经针对在服务器上运行的localhost smtp服务器测试了代码，该服务器工作正常，但在发送到第三方服务器时失败。
我尝试通过telnet手动发送电子邮件，而不使用身份验证，电子邮件通过第三方smtp服务器成功发送，所以我不相信服务器的限制。
我正在使用javamail-1.4.7。
我不明白为什么它正在尝试进行身份验证，即使它已被禁用

答案 0 :(得分：3)
它正在验证，因为您使用用户名和密码调用connect方法。
这有点令人困惑，但将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。将其设置为false可避免在这种情况下进行回调。但是，如果您明确传入用户名和密码，就像您正在做的那样，它假定您是故意这样做的，并且您希望使用它们进行身份验证。
答案 1 :(得分：0)
您可以更好地使用SMTPTransport
使其像
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);
}
使用Socket你需要导入java.net.Socket
