一个测试环境,现在想启用邮件服务(从系统中可以发邮件给用户),但是我发现我的Workflow Notification Mailer为'System Deactivated'状态,
点击Workflow Notification Mailer,可以看到详细的信息
Status Information:This automatic Service Component has been restarted the maximum of 10 times after stopping with error. Thus, it has been system deactivated -> java.lang.RuntimeException: Connection refused
