I don't know the answer to this one :)

What you got is the URN of a nco:PersonContact, that is, a "contact"
object. This contact can have one or more hasEmailAddress predicates
that point to EmailAddress objects (as far as I remember), and those
EmailAddress objects have one "emailAddress" predicate that holds the
textual email address (like foo bar org).

As far as I know plain text content of messages is not exported anymore
to Tracker, because it stressed evolution too much. This is a temporary
situation though.
