[ubuntu] system tray icon for mail-notification??

view story

http://ubuntuforums.org – I just installed 12.04 on a netbook and installed the program 'Mail Notification'. I tested it with my local (ISP) mail account and it works ie it gives a popup notifier and makes a sound. But there is no icon in the top panel for the program that shows a new mail message has arrived. On my desktop with 10.04, there is an icon, which continues to show even after the popup message has disappeared. How can I get an icon in 12.04? TIA (Hardware)
