Is this guaranteed to be right? I can't find dicumentation anywhere that says that Maildir folders HAVE to be in utf7-imap. Because quite honestly that doesn't make much sense - Maildir is not limited to use with IMAP. And/or a IMAP server might internally store everything in UTF-8 and only convert to utf7-imap internally when speaking IMAP to the remote client. At a minimum, I think that this needs to be a configuration option. And given that this is a point release, the default behavior needs to be the existing behavior at this point.

Umlauts and other utf7 characters in imap mailbox folder names get represented in utf8 instead of the utf7 encoding typcal for mailbox-folders. Consequently the folder is not found on the filesystem when maildrop runs with these filters. I created a patch addressing the issue by encoding the folder name when preparing the output to the maildrop script (ingo/lib/Script/Maildrop/Recipe.php).
