Ability to send “Copy Protected” mail that cannot be forwarded,
printed, or
cut/copy and paste.
Looking fwd to hear from you soon.
An email is just a file, mostly text, with "special" bits like images,
pdfs and zip files sent via smtp. There is no way you can "stop" the
recipient from doing anything they want with that file once they have
it on their computer.
You can encrypt part of the file (the email "body") to make it
unreadable by anyone without the proper decryption tool (or a very
fast quantum computer code breaker)...but once they have the file in
their possession, you have NO control or say over what they can do
with it.
The original poster may be referring to features such as Exchange's
Information Rights Management. This allows exactly this level of
control, but obviously only works within a controlled MS Exchange
environment. This type of feature, as already stated, is not going to be
available in a groupware stack built upon open standards such as IMAP,
SMTP etc...
Good point. I forgot that today you can send an email encrypted by one
of the several proprietary Information Rights Management (IRM) systems
(Oracle, Adobe, Microsoft, etc) and that email can only be decrypted and
used appropriately by someone with the same IRM system.
I did a bit of searching and did not find anything discussing any open
IRM standards that could be used by Horde or any other open source
application. But if such standards exist, I would hope we, the horde
community, could eventually expand the system to be able to offer it.
