Package: cyrus-imapd-2.4 Cyrus imapd loses annotations like expiration data, if the given mailbox moved to another partition. Moving and renaming mailbox uses the same command, if no moving just renaming happens, the annotations are kept.
Transcription from cyradm is attached. Annotations are stored by cyrus in a server-global database, when renaming happens, it needed to rename the keys of it. In imap/imapd.c:5708 the renaming function called unconditionally regardless of the name changed or not, but probably renaming to the same name should not delete it. The annotate.c and the relevant part of imapd.c haven't changed between 2.4.16-4+deb7u2 and 2.4.17+caldav~beta10-16, so probably jessie also affected -- Daniel Galambos / Dancsa
