Hi, I manually moved my var/vmail maildirs in a new machine (from ubuntu 18.04 to ubuntu 20.04) both with Ispconfig installed, using rsync. As I couldnt see the mailbox quota on ispconfig home, I followed Till suggestion about recalc quota. It worked but for some accounts I got some error/warning like: Shoud I worry about that (and maybe do something) or does Dovecot reindex/fix everything by itself? (on roundcube and thunderbird accounts seem to work). Thank you
