你看你错误信息英文翻译Sending the email to the following server failed :发送电子邮件到以下服务器失败：所以你下面的发送失败下面没有的说明发送正确
看看你发送正确页面信息改下错误的
smtp.saic-gm.com:25 这个服务器/端口 没有连上，你确认这个服务器正常工作么
1、确认端口是否是25，有些邮箱是会改的
2、确认是否仅支持ssl，25端口一般是非加密邮件，如果企业要求必须加密，则不会开放非加密的端口
3、这是企业及的邮箱，通常会限制发送方ip、mac等信息，所以如果你所处环境不对，也是不能发送的
可能是服务器对邮件的限制规则（比如邮件大小），所以有时候可以收到，有时不行
没有开启pop3.smtp服务
