AuthenticationFailedException:[EOF]向SMTP服务器发送未经身份验证的邮件时

我正在试图弄清楚，当smtp.auth属性设置为false时，为什么会出现AuthenticationFailedException。从调试日志中，它仍然尝试验证登录。我已经针对运行在服务器上的本地主机smtp服务器测试了该代码，该服务器工作正常，但在发送到第三方服务器时失败

我曾尝试通过telnet手动发送电子邮件，但没有使用身份验证，并且电子邮件通过第三方smtp服务器成功发送，因此我不认为这是服务器的限制

我正在使用javamail-1.4.7

调试输出 我不明白为什么它试图验证，即使它被禁用
