Guys, I need you help. Could you please try to reproduce and inform me - is this problem actual for you? I need any feedback from you regarding this problem. I'm not found any mentions about this problem on forum and I want to know how serious the problem is and how much users does it affect? STEPS TO REPRODUCE: Create reseller, grant him all permissions, log in as reseller, create domain with mail hosting, try to disable mail service for this domain. ACTUAL RESULT: Panel allows to uncheck 'Activate mail service on domain' checkbox and click OK. No errors are reported. Mail service is on for domain. Settings had not changed. EXPECTED RESULT: Mail service should be disabled settings should be changed Thank you very much for your help and cooperation!
