My English is poor , When do something. For Example deleted an file , Show send mail to admin ,But Can't get the mail. set is right. if setup agaim,It can get the mail success only once.
I guess you have a custom ADD-IN which triggers a notification to ADMIN when a file is deleted.I'd recommmend you talk to Your VAR.
