Hi, We need message size control for Incoming & Outgoing mails.We having 2 types are users set - One should allowed message size 10 Mb & other should allow upto 5 Mb only.On Domain i can set Message size limit but for user base deafult option not present.Again i want when user try to send message on localy it should check message size and block mail if message size more than his limit before routing.
