Pls be noted that we will set servers including ufbkkap(192.168.51.254), ufbkkaplx01(192.168.51.225), ufbkkaplx02(192.168.51.226) auto shutdown at 18:00.
May I know how long will you finished the removal and boot the servers up? If the mail server is shutdown over 4 hours, users will not receive the emails during the down time, you may need to send global email to inform users about that.
