[otrs] Problems with group of email

Hello all, I set up my system to automatically respond to the customer when a new ticket is created. It works if the customer uses its own email (eg customer@company.com), but it does not work using a group of email (eg noc@company.com or support@company.com). I can´t understand what happens. Anybody knows why I can´t use group of email? Best regards, ------------------------------- Carlos Eduardo Ribas
