maildirwatch - look for new mail in a maildir
maildirwatch watches your maildir for new mail. You must supply a MAILDIR environment variable with the name of your maildir directory. maildirwatch prints a new mail summary twice per minute. It is designed to run inside a (VT100-compatible) window; it clears the window before each summary.
