How to Pass Through Inbound Email with S/MIME Certificates
Last Updated February 16, 2015
Bypass S/MIME email from Symantec Encryption Desktop (previously PGP Desktop) and let the messages be processed by Microsoft Outlook.
For a standalone version of Symantec Encryption Desktop:
1. Close Symantec Encryption Desktop and Exit PGP Services from the PGP Tray icon in the Taskbar. 2. Click Start and select Run. 3. Type %appdata% and press Enter. 4. Open the PGP Corporation > PGP folder. 5. Inside the PGP folder is a file called PGPprefs.xml, right-click the file and open it with WordPad. 6. Find the passthroughInboundSMIME key and change the value from false to true and save the file. 7. Restart the PGP Tray (Start > Programs > Startup > PGP Tray).
For a managed Symantec Encryption Desktop:
1. Go to Consumers > Consumer Policy and select the desired policy
2. General and select Edit.
3. Edit the xml preferences and type into the Pref name: passthroughInboundSMIME type: boolean value: true.
4. Re-enroll the Desktop client.
The PGPprefs.xml file has two portions. The top portion is the Client pref. The bottom portion is the Admin pref. Both of these portions have all the same settings in theory, such as "inboundsmimepassthrough".
The top portion, or standalone prefs should be used when the client is a standalone client, not managed by the Symantec Encryption Management Server. Any changes made to the top portion should remain if a standalone client is being used, and the preferences in the top portion should be honored, if the client is standalone. As this is standalone, there are no restrictions with what a user can do.
If "inboundSMIMEpassthrough" is set to "true" in the top portion of the prefs, and the client is standalone, then the client should honor it.
If the client is managed by the SEMS, then modifying the bottom portion of the PGPprefs.xml, or admin prefs, should be reverted, as the client will only use what is pulled down from the Symantec Encryption Management Server, and prevent tampering by users.
Client prefs can be modified via the PGPprefs.xml file. The Admin prefs must be modified on the Symantec Encryption Management Server.
