I would like to see both the scroll bars (vertical & horizontal) on at least the
listbox under the Search button so more of the email address could be seen as we would have staff and students/alumni with the same name as well as multiple students/alumni with the same name with a slight variant on their generated e-mail address.
In relation to the the drop down list of Address books/global address lists we would definetly need a facility where staff, students and alumni would need to be broken down into seperate group listings with the option as well to search all and ideally on each instance/mailserver to be able to set the staff address book as the default for the staffmail server so they would only search the staff address book otherwise they would have to select all Global Lists from the dropdown if they needed to search other addresses. The same would apply on the student email server in the student address book may be set as the default global list to search (should be customisable so that the
administrator can decide which address book is the default for the instance of Zimbra).
This feature along with some type of Newsgroup/RSS feature/plugin would probably swing our decision to go with Zimbra as opposed to the others we are looking at. With the Newsgroup feature/plugin that we have at the
moment, rather than allowing staff/students send allstaff or allstudent emails about anything and everything we have a newsgroup that is the first thing they see when they login and they can read the messages posted or post new ones (simply to post all they have is subject, message body, and an option to add a file). If they choose to ignore they click on the inbox and get up their mail (Maybe a tab before "Go To Mail" that could be set as default)
Another feature staff have asked for in existing mail app was that you could add multiple documents from the one folder all in one go.
Hope this helps
