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...
