http://dovecot.org/releases/dovecot-1.0.rc29.tar.gz http://dovecot.org/releases/dovecot-1.0.rc29.tar.gz.sig

Probably one more RC after this.

* Security fix: If zlib plugin was loaded, it was possible to open
  gzipped mbox files outside the user's mail directory.

+ Added auth_gssapi_hostname setting.
- IMAP: LIST "" "" didn't return anything if there didn't exist a
  namespace with empty prefix. This broke some clients.
- If Dovecot is tried to be started when it's already running, don't
  delete existing auth sockets and break the running Dovecot
- If deliver failed too early it still returned exit code 89 instead
  of EX_TEMPFAIL.
- deliver: INBOX fallbacking with -n parameter wasn't working.
- passdb passwd and shadow couldn't be used as master or deny databases
- IDLE: inotify didn't notice changes in mbox file
- If index file directory couldn't be created, disable indexes instead
  of failing to open the mailbox.
- Several other minor fixes
