I'm not sure which client created it and if any of my clients
does support special_use, but I found the following mailbox on
our mdbox filesystem:

# ls -ld mail/mailboxes/Entw\&APw-rfe
drwx------ 3 vmail vmail 4096 2012-05-22 19:58 mail/mailboxes/Entw&APw-rfe

Seems like k9mail or Android Mail must have created it in May 2012,
the folder is not subscribed and contains only a single mail. The
rest is in "Drafts" mailbox (where it belongs).

Daniel
