Alessio and Peter thank you again. maybe it can be future request. :)
We are trying to tell you that it is impossible to write a mail _client_
that does not download (i.e. transfer) the mail that it shows to the user.
This is why it makes no sense to prevent the download on the server
side, and so there will never be such a function.
Preventing the download (the transfer) of the mail fro mthe server to
the client just means that the user *cannot read it*.
Another question is whether there are mail _clients_ which do not offer
a possibility to *save* the read mail (which has already been
"downloaded" for reading it). But that question is not really related to
the dovecot mail server.
If you want to get users to read mails, but not download them, I would
suggest you deny the direct access to the mail server and use a
browser-based application that shows the entire mail to the user, maybe
as a graphical representation. Or you use some sort of terminal
software that connects to a host where the mail _clients_ itself are
installed, just letting the user view the data but nor copy it, e.g. the
VNC protocol.
Hope this helps,
