ES1 for Lotus Domino - Making journaled encrypted emails accessible and searchable?

Hi,

I´m testing searhes from SourceOne Search and noticed that encrypted emails show no content in their body (blank). This makes sense since this is what encryption is for but... For Ediscovery puposes we need to be able to search content, access, review and export those messages.

Is there a way ES1 can decrypt those mails before archiving them?  If not, Is it possible at least to open, read and export those encrypted emails?  This enviroinment has potentially 30,000 users so adding all encryption keys to the ES1 services Notes ID and auditor´s ID is not a possibility.

Any help on this will be very appreciated.
