GLD-fork is a fork of the GLD program by Salim
Gasmi. The fork has been made because the original
project has been dead for many years, and some new
featured were needed. GLD-fork, as with the
original GLD, adds greylisting functionality to
the Postfix mail server. Greylisting is a fairly
resource friendly anti-spam technique. GLD-fork
can easily be combined with other (more resource
consuming) tools to build anti-spam protection.
