Ive now had 2 reports from people on roundcube that they briefly saw an email that was meant for someone else. We dont use caching. Is there still a way where theoretically 2 emails could get mixed up within roundcube? Some temp file or whatever? Im of course also looking at the imap server, but cant rule out roundcube yet..
