Hi,

I have a Exchange 2013 Server. Now as a User I want to redirect some Emails to an email address which is not in my Exchange Server.

But for security reasons I want that every email that will be redirected should be encrypted with the PGP Key of the receiver.

Is there any solution how I can solve this? Maybe with an Agent but I think that isnt possible. Maybe I have to setup up a small mail server for receiving the mail from the exchange than encrypt and redirect.

If the messages needing to be sent encrypted will only be coming from your machine then you could probably get away with Symantec desktop encryption http://www.symantec.com/business/support/index?page=content&id=DOC6205 which I believe will plugin to your Outlook and encrypt the messages (where possible) when they leave. If they'll be going from multiple users, or directly from Exchange then you'd probably need the gateway email encryption version http://www.symantec.com/gateway-email-encryption?fid=encryption .

Note while I've heard good things about them I haven't used either so can't confirm how well they work in the real world, but they're probably your best option.
