请教 ：grails mail发送失败 或给个详细例子
我的代码

Config.groovy配置
grails {
  mail {
  host = "smtp.qq.com"
  port = 465
  username = "**********@qq.com"
  password = "***********"
  props = ["mail.smtp.auth":"true",
  "mail.smtp.socketFactory.port":"465",
  "mail.smtp.socketFactory.class":"javax.net.ssl.SSLSocketFactory",
  "mail.smtp.socketFactory.fallback":"false"] }
}


MailController 

package mail
import org.grails.mail.MailService

class MailController {

  def mailService

  def mailNotice = {
  println("------------------")
 
  mailService.sendMail {
  to "**********@qq.com"
  
  subject "Hello John"
  body 'this is some text'
}

  }


}
我在GSP 页面写了这个 <a href="mailNotice">dd</a> 测试能否发送 

但是不能发送QQ邮箱  

错误代码

抱歉GRAILS我没接触过。按错误提示看是认证失败。
