geximon is a Gtk2 reimplementation of eximon, an X monitor for the
exim mail transport agent. It has all the features of the original
(tracking the log, managing the mail queue, plotting, etc.) and more.
It integrates with exiwhat (allowing you to manage exim processes),
exigrep, and eximstats. It can utilize sudo, so that you don't need to
run the program itself as the superuser. The interface is intuitive,
compact, and easy to use.
