Nbiff is yet another biff-variant. Unlike other biff programs, however, nbiff does not watch mailboxes itself but requires to be notified by a short network contact passing sender address and subject. This is usually done by its companions notifynbiff and nbiffd.
Currently, notifynbiff is tailored for the use in ~/.qmail configuration files.
It is written in Perl and requires following packages: MD5, Net::Domain, and Tk.
