    1.14  The \masqmail\ project\index{masqmail!the project} was initiated by \person{Oliver Kurth} in 1999. His aim was to create a small \MTA\ that is especially focused on computers with dial-up Internet connections\index{dial-up}. Throughout the next four years he worked steadily on it, releasing new versions every few weeks. During the active phase of development 53 version have been released. In average, this is a new version every 20 days.

    1.32  Although the development on \masqmail\ has been stopped in 2003, \masqmail\ still has its users. Having users is already reason enough for further development and maintenance.
