Tray Helper it's small award winning application with many features (f/e: email checker, auto mail responder, anti-spam, popup-killer, event reminder and more).

There was a new version (2.9) released recently (Oct 11, 2002) with following changes:

• Application can notify you about new mail with Animated New-mail Tray Icon. Thanks to this feature you can faster and easier find out how much mail is waiting for you on your accounts.
  
• TH looks better now, and in addition you can customize some elements of this outlook.
  
• Removed bug from e-mail checker module (it was a quite ugly one but also VERY RARE).
  
• Removed few minor bugs and added some features.
  
• HUNGARIAN language support -> thanks to: Jozsef Tamas Herczeg.
