I am pleased to announce the release of Cyrus IMAPd 2.3.16.  This
release should be considered production quality.  Major changes in the 
release are the following:

- Added 'user_deny.db' to be able to selectively deny users access to
   Cyrus services.
- Added 'popuseimapflags' option which enables setting and
   obeying IMAP flags in the POP server.
- Added optimized method of handling an empty maildrop in pop3d.
   (based on work of Cyril Servant <elfejoyeux at>)
- Added 'annotation_definitions' option for specifying
   external (third-party) annotations. (courtesy of Thomas
   Viehmann <tv at>)
- Added COMPRESSion to replication protocol. (courtesy of Bron Gondwana
