geximon
geximon is a clone of eximon, the exim server monitor. The original program is functional, but, to cite one of the exim mailing list members, "it could use a visit from one of the Learning Channel redecoration shows :-)"
geximon is written in Python and uses pygtk, which is a Python binding to GTK+. The source code is available under the GNU General Public Licence.
Version 0.7 released on 10th April, 2004.
Download: geximon-0.7.tar.gz (Debian package)
