If a folder has new messages, then it has a badge that is dark blue (with the theme I am using) with the number of un-read messages. Otherwise it has a badge that is light-blue to indicate un-read messages only. Folders with no badges have zero un-read messages. So there is definitely a distinction for "new" messages.

migration from 2.0.16

I have an old server with CentOS 6.x and dovecot 2.0.16 (postfix-2.6.6 and roundcube), that was an update from a 1.x many years ago ... Users in /etc/passwd Mailbox format mbox some filtering via procmail About 5.000 users, 1 TB data (/var/mail + /home/users) Obviously I am searching for a smooth upgrade path (with no or minimal downtime and users problems) ;-) Until few days ago my idea was a CentOS 8.x new box with the standard default packages (dovecot-2.3.8, postfix-3.3, ...). Now this can be reconsidered. I suppose there will be a RockyLinux or something equivalent but if there is a good reason I can consider Debian or other OS if they have a decent EOL or some advantages. Anyway, the more relevant problem at the moment is collect info for the best approch to have a smooth dovecot upgrade. My dream is the possibility to configure a new server and rsync the data (/var/mail + /home/users), and, when the tests are satisfiable do the final sync and swap the IP, but I suppose deleting the .imap folders isn't a simple complete solution to compatibility problems. Any hints, links, experiences are appreciated. Thanks, B.

Initial Replication
by David Morsberger 01 Jan '21

I searched the archives and do not see a question/answer for this. Should I perform a set of ordered steps after setting up replication? I have setup dovecot on both ends with identical config except for the remote hostname. Main concern is the existing server gets replicated to the new server. I want nothing from new server replicated to the old server. Risking "Trial and error" and "crossing fingers” doesn’t work with production emails Specifically: Do I need to setup the mail directories for the various virtual users on the remote? If so, do the directories need to empty? Should I initially do a manually one-way synch using doveadm from the existing server? If so, is there a way of turning off automatic replication while the manual one runs? Anything else? T David
