各位，请教
在Doris manager 的服务配置处， 我设置了邮件服务器的协议为SMTP， SSL/TLS为无，邮件服务器地址为公司内部smtp.xxx.com , 端口为25。但每次发送警告或消息邮件失败，无法连接到smtp服务器。
公司邮件服务器信息：服务器：smtp.xxx.com;端口：25;身份验证：无; SSL/TLS：无
1， 当我将用户名，密码，独立发件人地址密码全部为空时，根据日志，发邮件时将会默认使用内置doris帐号向smtp服务器验证，参考日志如下：

- 当我填写上正确的用户名密码时，发送邮件仍然失败，是由于smtp 服务器不支持用户名密码验证。

由于不能修改smtp服务器的认证设置，因此有什么参数可以设置邮件通知的配置文件不使用默认的linux帐号进行验证呢？或有别的方法可以绕开这个验证吗？
另外补充一点，我用telnet smtp.xxx.com 25 发送邮件是正常的。
非常感谢大家的支持和帮助。
