I was engaged to theoretical physics on quantum dynamics of solid surfaces by means of analytical and computational methods. This research was carried out by composing Fortran and shell script codes on unix-like systems.
From 2003, I switched my computer life to FreeBSD system and aquired sufficient knowledge on open-source systems for doing the all daily business and private work only be FreeBSD. From 2006, I started a private project for developing an email server system which implements a new junk mail filtering mechanism based on white lists and authentication.
The server system is being developed as a software package for installation/administration of an integrated internet server system for personal and enterprise businesses. This project is still in the phase of closed development. The first release is planned to be shipped as an open-source software at least partially.
