Just a cosmetic problem, of course. Some IMAP clients do sort folders,
others do not, so they show different folder sort order in Dovecot, if 
migrated from Courier (Courier seems to sort folders, so that the system 
ones appear first). We just needed a seamless migration.

So, it is legal to even list each folder several times?
