I've been using Mozilla's Thunderbird mail client for quite a while now for all my dotnet.org.za and private mail; and it's really great. As with all Mozilla apps, I find it takes a bit of tweaking and customizing to get it suited perfectly to your habits/preferences. I've been looking for a way to minimize it to the tasktray (ala Outlook). Thundertray does just this. I just changed my shortcut to point to "C:\Program Files\Mozilla Thunderbird\thundertray.exe" and then it always runs in the tasktray...
