[dovecot] 0.99.5 released

v0.99.5 2003-01-02 Timo Sirainen tss@iki.fi

* This release includes a lot of code cleanups, especially related to
  security. Direct buffer modifying was replaced in several places
  with a new buffer API, which provides a safe way to do it. Code that
  looks unsafe contains @UNSAFE tag to make auditing easier.

+ Support for SORT extension. Originally I thought about not
  implementing any extensions before 1.0, but too many people want
  webmails which want SORT. THREAD is another extension which they
  want, but we don't support it yet.
+ imap_listen and imaps_listen settings now accept "*" and "::" to
  specify if we want to listen in IPv4 or IPv6 addresses. "::" may
  also listen in all IPv4 addresses depending on the OS (Linux does,
  BSD doesn't)
+ New setting: default_mail_env can be used to specify where to find
  users mailbox. Default is still to use autodetection.
+ New setting: imap_log_path to log logins etc. informational messages
  to different file.
+ We support now separate mbox file for INBOX folder, no need for
  symlink kludging anymore.
+ Support for keeping index files in different location than actual
  mailboxes.
? Disabled mailbox_check_interval setting by default, it breaks
  Evolution.
- SEARCH was still somewhat buggy, especially with laggy networks.
  Also body/header searches might have crashed or at least used
  memory too much
- Deleting messages in the middle of mbox caused dovecot to reindex
  the following messages as new messages (ie. change UIDs and set
  \Recent flag).
- Digest-MD5 auth: Initial server challenge packet was missing a comma,
  which might have made it incompatible with some implementations.
- Some more fixes to unnecessarily high memory usage
- SELECT and EXAMINE often printed UNSEEN reply or maybe complained
  about corrupted indexes. Happened usually only with mbox.
- FETCH BODYSTRUCTURE gave incorrect reply, breaking pine
- LIST was pretty buggy with mbox subfolders
- CHECK command returned just "missing parameters" error
- DELETE didn't work with mbox folders
- CREATE mailbox<hierarchy separator> failed always.
- CREATE and RENAME didn't create required hierarchies with mbox
- RFC822 date parser didn't handle single digit days correctly.
- login_process_per_connection = yes didn't work with imaps port
  connections which is exactly where it was mostly wanted.
- ssl_disabled = yes didn't disable listening in imaps port
- process limiting code didn't compile everywhere (eg. FreeBSD).
- Linux sendfile() was never detected
- We didn't work at all with gcc/PowerPC
