        Hi,
that's weird, but maybe as Andre said, packaging can disable it, or
even not build it at all. It depends. Though if you have
File->New->Mail Message and in there File->Compose in External Editor,
then the plugin is surely there. The same as it should be in:
   /usr/lib64/evolution/plugins/liborg-gnome-external-editor.so
   /usr/lib64/evolution/plugins/org-gnome-external-editor.eplug
(The actual path can differ on your system, but the files should be the
same.)

Brewster, the plugin stores its settings in GSettings, thus you can for
example:
   $ gsettings get org.gnome.evolution.plugin.external-editor command
to see what is stored there, and you can also:
   $ gsettings set org.gnome.evolution.plugin.external-editor \
       command "gvim -f"
to change the value to gvim, like in UI.

It would still be interesting to know why you do not see the plugin in
Edit->Plugins though (supposing the plugin is built and its files
available). The org-gnome-external-editor.eplug can have set it as a
"system" plugin, which are hidden in UI configuration, but that's not
the case for the upstream version.
        Bye,
