(like how a web browser might receive zipped content and > unzip it to build the webpage on the client). Dovecot has two (relevant) plugins. zlib compresses the stored emails. This is transparent to all clients - exim provides uncompressed emails, dovecot compresses them to disk and on-the-fly decompresses them when serving them back to mail clients. There is also imap_zlib which works like the HTTP gzip extension. IMAP communications are compressed, allowing fewer bytes to be sent between the server and the clients. > > Oh and the system_filter saves files directly to backup areas that are > not users on the system; so I have some work to do on that as well. > > Thanks > AndrewM >
