项目需求要更换发邮件服务器，变更成中转邮箱服务器发邮件。结果总是报 No authentication mechansims supported by both server and client 。
搜了一堆东东，都不靠谱最后自己不断调试成功搞定。借鉴网址如下：
原因：中转服务器不需要验证用户名密码啥的，所以链接的时候
MAIL_SMTP_AUTH 要设为 false。
transport.connect();//中转服务器邮箱不验证 连接的时候不要传东西，哪怕是 null 或 空 。它会认为你要验证。
（首先保证自己的发邮件服务器和应用服务器想通的。并且邮件服务器端口正确，默认是25（telnet 192.168.1.114 25））
