If you use IMAP you can set ACL and enable read only for the folders: http://wiki2.dovecot.org/ACL -- Alessio Cecchi is: @ ILS -> http://www.linux.it/~alessice/ on LinkedIn -> http://www.linkedin.com/in/alessice Assistenza Sistemi GNU/Linux -> http://www.cecchi.biz/ @ PLUG -> ex-Presidente, adesso senatore a vita, http://www.prato.linux.it

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. /Peter

do you mean to leave a copy of the email on the server so it can be read in multiple email clients? IMAP can do this and i think modern POP3 can. look for an account config option in your mail client to "leave mail on server". i think there is a setting in dovecot to prevent expunging of email but it has been years since i was researching this. -david On 09/20/2012 02:21 AM, Selcuk Yazar wrote:> Hi, > > can we prevent download messages from server user by user ? sme common used > mail's message must be remain at the server, but sometimes we download them > ? > > thanks in advance >
