I'm using Zimbra Release 7.1.0_GA_3140.RHEL5_64_20110329135300 RHEL5_64 NETWORK edition.

Right now if I start to type in a recipient's name in the TO: or CC: fields I get both "user.name@company.com" and "user.name@mail.company.com" results for my internal users. Is there a way to globally restrict the options to just see the results of the @mail.company.com listings for all users?
