i want to hide the "View mail" button on administrator web panel on the Manage Accounts menu. i'm using the open source version.

i've been "searching needle in the hay stack" here: /opt/zimbra/jetty/webapps/zimbraAdmin trying to figure out a way to hide that button.

i'm thinking either disable it from the AJAX script or simply hide it using CSS style, but it seem to not work.

any pointers would be appriciated. thank you
