I have moved from dovecot 1.x to 2.x and I have big problem with subfolders. When I'm moving subfolder with other subfolders is moving only main subfolder, without subfolders, example :
mail-storage-1 /var/vmail/home/adamskitest/mdbox/mailboxes # find | egrep -e "janusz|jarek" ./jarek ./jarek/dbox-Mails ./jarek/dbox-Mails/dovecot.index.log ./jarek/jarek2 ./jarek/jarek2/dbox-Mails ./jarek/jarek2/dbox-Mails/dovecot.index.log ./jarek/jarek2/jarek3 ./jarek/jarek2/jarek3/dbox-Mails ./jarek/jarek2/jarek3/dbox-Mails/dovecot.index.log ./janusz ./janusz/dbox-Mails ./janusz/dbox-Mails/dovecot.index.log ./janusz/janusz2 ./janusz/janusz2/dbox-Mails ./janusz/janusz2/dbox-Mails/dovecot.index.log ./janusz/janusz2/janusz3 ./janusz/janusz2/janusz3/dbox-Mails ./janusz/janusz2/janusz3/dbox-Mails/dovecot.index.log
And now I'm moving jarek2 with jarek3 as subfolder to janusz2 subfolder, result :
mail-storage-1 /var/vmail/home/adamskitest/mdbox/mailboxes # find | egrep -e "janusz|jarek" ./jarek ./jarek/dbox-Mails ./jarek/dbox-Mails/dovecot.index.log ./jarek/jarek2 ./jarek/jarek2/jarek3 ./jarek/jarek2/jarek3/dbox-Mails ./jarek/jarek2/jarek3/dbox-Mails/dovecot.index.log ./janusz ./janusz/dbox-Mails ./janusz/dbox-Mails/dovecot.index.log ./janusz/janusz2 ./janusz/janusz2/dbox-Mails ./janusz/janusz2/dbox-Mails/dovecot.index.log ./janusz/janusz2/dbox-Mails/dovecot.index.cache ./janusz/janusz2/janusz3 ./janusz/janusz2/janusz3/dbox-Mails ./janusz/janusz2/janusz3/dbox-Mails/dovecot.index.log ./janusz/janusz2/jarek2 ./janusz/janusz2/jarek2/dbox-Mails ./janusz/janusz2/jarek2/dbox-Mails/dovecot.index.log
As You can see there is jarek2 subfolder but jarek3 havent been moved. I can see this folder in Thunderbird, after clicking error message pops out saying folder dosent exist.
