You now have to use the true utf-8 name of the folder in your sieve script, and it's automatically converted to the modified utf-7 folder name internally. This change is noted in the changelog for 2.3.11 --- The Sieve compiler now translates UTF-8 mailbox names used in fileinto to modified UTF-7 so that messages will be successfully inserted into the mailbox. --- The old way of using the modified utf-7 form in the sieve script was really wrong and hacky.
