如何把gitlab项目中的提交、PUSH、合并请求的通知发送到邮箱

己在/etc/gitlab/gitlab.rb配置文件对以下进行设置了

   # gitlab_rails['smtp_enable'] = true 
   # gitlab_rails['smtp_address'] = "smtp.126.com" 
   # gitlab_rails['smtp_port'] = 465 
   # gitlab_rails['smtp_user_name'] = "username" 
   # gitlab_rails['smtp_password'] = "xxxxxxx" 
   # gitlab_rails['smtp_domain'] = "126.com" 
   # gitlab_rails['smtp_authentication'] = "login" 
   # gitlab_rails['smtp_enable_starttls_auto'] = true 
   # gitlab_rails['smtp_tls'] = false

请高手指点！谢谢！
