Re: [Dovecot] Prevent Download messages from server
we have no problem, just i want to learn how can i do that. i think it's clear .
Well... I'm pretty sure most others don't.
But anyway. As in ALL Internet protocols (IMAP being no exception), letting the client read data on the server requires it to download the data. Preventing download will prevent reading the mail. Period.
So if you're fine with that and just want to learn how to do it, then just disable the account in the user database.

Alessio and Peter thank you again. maybe it can be future request. :)

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, Jakob Curdes
why are you trying ??? this is brain storming
