The actual headers you can insert into messags seems to be controlled from:
/usr/share/glib-2.0/schemas/org.gnome.evolution.plugin.email-custom-header.gschema.xml
<?xml version="1.0" encoding="UTF-8"?>
<schemalist> <schema path="/org/gnome/evolution/plugin/email-custom-header/" id="org.gnome.evolution.plugin.email-custom-header" gettext-domain="evolution"> <key type="as" name="custom-header"> <default>['Security=Personal;Unclassified;Protected;InConfidence;Secret;Topsecret']</default> <summary>List of Custom Headers</summary> <description>The key specifies the list of custom headers that you can add to an outgoing message. The format for specifying a Header and Header value is: Name of the custom header followed by “=” and the values separated by “;”</description> </key> </schema> </schemalist>
This custom header is a plug-in, and the plug-in manager does let you edit the options without having to hand-edit the XML file. But if you were customising Evolution for a whole organisation, you probably would want to create custom override XML files.
If a mail header specifies a sensitivity level, when the mail is read in Outlook it adds a message above the subject to treat the mail as whatever sensitivity is specified (except if there is no sensitivity, in which case the sensitivity header is absent). regards, Steve
