ThunderBird is a powerful email client launched by Mozilla. It can replace Evolution in Linux (equivalent to Outlook in Windows). I believe everyone is using it. If you use Ubuntu 9.04, install this plug-in for ThunderBird so that it can use the LibNotify new notification system! You can also right-click here and select "Save as" to download the plug-in, install it in ThunderBird, and restart the plug-in after installation. If there is a new email in ThunderBird, the system will pop up with a prompt.

In addition, if you want Firefox to use the new notification system of Ubuntu 9.04, install the FirefoxNotify plug-in for Firefox.
In addition, compared with the previously introduced CheckGmail, gm-notify can use the Ubuntu new notification system to pop up a new email prompt when there is a new email in the Gmail mailbox.
Note: gm-policy is not GmNotify, Gmail Notifier, or Firefox plug-in Gmail Notifier. Although the other four programs/plug-ins can bring up a prompt when Gmail has a new email, however, it seems that only gm-notify can use the Ubuntu notification system. Of course, compared with GmNotify or Gmail Notifier, gm-notify has the least function.
To install gm-notify, search for gm-notify in the new version and install it. Or run sudo apt-get install gm-notify directly.
