Use Windows Rights Management or one of the security services listed at

Only viable for users within the same Exchange organization? What if
the recipients don't use Outlook? What the OP wants can only be
enforced in a small configuration of mail server and e-mail client. RMS
requires the user to log onto a domain using Win2003 with RMS and also
using an e-mail client that supports RMS, like OL2003 (or maybe the
end-users are expected to install the RMS client on their hosts). So
interdepartmental e-mail within the same company could be controlled.

With the plug-ins to Outlook that try to track when a mail is delivered
and when it is read, and some working with a server to regulate who can
read them and how long they can read them, that still doesn't prevent
someone from using a screen capture program, some of which will capture
as text (so no OCR is needed), to then edit it however they want. Since
the mail must somehow be presented in a form viewable and readable to
the recipient, poof, there goes any security that tries to restrict the
content of that mail. The use of these plug-ins requires that the
recipient install them. Not likely, as they aren't going to waste their
time to install software that *they* don't need just because some sender
would like it. Unless the OP is asking about delivering mails within
the same organization (i.e., sender and recipients are in the same
company) where some leverage can be applied to force recipients to
install software or follow policies, the use of the security plug-ins or
services pretty much guarantees that the recipients won't be able to
read his mails.

The OP, as the sender, wants to control what the recipient can do on
their own host. Not going to happen. The OP has provided no
information regarding who and where are her recipients and yet with such
vague information she wants specific help.
