SmarterMailMon monitors POP and IMAP mail accounts for new messages. It runs in the system tray and will blink when new messages are available.
 
The source code version is different than the executable because of 3rd party library dependencies. As a result, the source code does not have a lot of the UI elements, but includes all the logic for grabbing the messages counts from POP and IMAP accounts.
