From 522ba399d24e8166681b328f550904fcd4d8fad9 Mon Sep 17 00:00:00 2001 From: Guilhem Moulin Date: Mon, 16 Dec 2013 04:29:55 +0100 Subject: Use a local IMAP caching proxy under the webmail. (Unless the webmail is itself a full IMAP server.) It replaces RoundCube's own IMAP and message caches. Dovecot's IMAPC storage backend is not very documented, but provides smart IMAP proxying.
