qmailcheck looks for new mail in multiple IMAP mail boxes. If you get a lot of mail and split the messages into separate boxes (typically on the server side using procmail or sieve), then checking all the boxes by hand can be tedious. QMailcheck displays the results in a formatted list, highlighting the newest items. When new mail arrives in a folder, it is capable of raising the window, issuing a system notification, flashing the LED (on phones only), and vibrating (on phones only), all on a per-folder basis.
