You may want to consider setting up a Connector to identify emails sent from your server.  This method is much more effective than using a GPO Push.  Contact your Account Representative for a copy of the documentation on how to do this.

How to add the PoliteMail Server to your IE Trusted Zones file

To more effectively track email, the PoliteMail Server should always be included within your network’s trusted zones.

This is an Internet Explorer security setting which blocks content from untrusted sites, and the user will be asked to “download content from an unknown website”. To avoid this, and enable automatic content download and open tracking for internal email, place the PoliteMail Server name into the trusted zones file.

If the PoliteMail Server subdomain is not contained within an already trusted wildcard domain, then the domain name may be manually added to the trusted zones file on an individual machine (to test the result). However, is it best to implement this company wide using Group Policy [GPO] or Microsoft InTune.  Use this reference chart to determine which policy fits your organization’s needs.

To see the list of existing trusted zones within your network

Start IE, then put the PoliteMail Server domain name into the IE address field. You should see a “Loading…” message. Now use IE > Tools > Internet Options > Security tab, and click Trusted Sites, then the Sites button below.

To Manually Add a Site to the Trusted Zones

Follow the instructions above to see the list of trusted zones, then type the full URL domain name for the PoliteMail Server (including http:// or https:// ) into the Add this website to the zone field, and click the Add button.
