   Log Message:
   Update to Dovecot 2.0.16.

   * VSZ limits weren't being enforced for any processes. On server with
     large mailboxes you may now see errors about it if the limits aren't
     high enough. To fix them, either increase individual service {
     vsz_limit } values or simply increase the default_vsz_limit setting.
   * Proxying: If using ssl=3Dyes or starttls=3Dyes with a hostname (not IP)
     as proxy destination, require that the certificate matches the given
     hostname.
   * LMTP: Changed default client_limit to 1. This should improve LMTP
     throughput with default settings.
   * dsync: Quota is no longer enforced (i.e. dsync can't fail because
     user is over quota).

   + Added "auto" mail storage driver, which can be used to autodetect
     mailbox location and format. This behavior is already the default
     for empty mail_location setting, so this change is mainly useful for
     shared namespace's location setting.
   + checkpassword: Export all auth %variables to AUTH_* environment.
