	parse lang.codeset@modifier string in LANG.

	* rfc822/encodeautodetect.c (libmail_encode_autodetect): Remove obsolete
	unicode API. Determine encoding with heuristics based entirely on
	the content. Remove charset arg, replace with "use7bit", to force
	qp or base64, instead of 8bit. Take a binaryflag param that gets set
	to indicate whether base64 was selected based on binary content.

	* pcp/pcp.c (usage): Unicode API update.

	the default system unicode charset based on the global locale.
	(libmail_u_convert_init): Support a phony character set used to
	encode unicode folder names for IMAP (and SMAP). Passing the
	phony character set name to libmail_u_convert_init() encodes or
	decodes to the phony character set. For converting to the phony
	character set, libmail_u_convert_init() sets up an iconv conversion to
	UCS-2, then wraps it into a module that converts UCS-2 to the phony
	character set. For converting from the phony character set,
	libmail_u_convert_init() sets up an iconv conversion from UCS-2, then
	wraps it into a module that converts the phony character set to UCS-2.
	(libmail_u_convert_tocbuf_init): A wrapper to libmail_u_convert_init()
	that converts to native UCS-4, and saves it into a malloc-ed
	unicode_char array.
	(libmail_u_convert_tocbuf_toutf8_init): Convenience wrapper for
	converting to UTF-8.
	(libmail_u_convert_tocbuf_fromutf8_init): Convenience wrapper for
	converting from UTF-8.
	(libmail_u_convert_toutf8): Convenience wrapper that converts
	a text string to UTF-8 and returns a malloced buffer with the
	converted string.
	(libmail_u_convert_fromutf8): Convenience wrapper that converts
	a UTF-8 string to another charset, and returns a malloced buffer with
	the converted string.
	(libmail_u_convert_tobuf): Convenience wrapper that converts a
	character string and returns the converted string in a malloced
	buffer.
	(libmail_u_convert_fromu_init): Convenience wrapper that sets up
	a conversion of text to native unicode_chars.
	(libmail_u_convert_uc): Convenience wrapper for passing unicode chars
	through libmail_u_convert().

	* rfc2045/rfc2646create.c (rfc2646create_alloc): Replace unicode
	struct pointer argument with a character set string name.
	Use libmail_u_convert_fromu_init() and libmail_u_convert_tou_init()
	instead of the obsolete unicode functions.

	* rfc2045/rfc2231.c: Replace the unicode struct pointer argument with
	a character set string. Use libmail_u_convert_tobuf() instead of the
	obsolete unicode functions.

	* rfc2045/rfc2045decodemimesectionu.c (rfc2045_decodetextmimesection):
	Add a return value indication of a failed conversion to the requested
	character set.

	* maildir/maildirinfo.c: Use libmail_u_convert_tobuf() instead of the
	obsoleted unicode functions.

2011-01-09  Sam Varshavchik  <mrsam@courier-mta.com>

	* all: Replace all usage of internal unicode tables with iconv.
	Courier-IMAP now supports searching text given in any character set
	that's supported by iconv. The internal unicode library is still used
	for converting unicode to/from lower/uppercase, for functionality
	not directly available in iconv. Pretty much a rewrite of the entire
	search/sort/thread implementation.

2011-01-08  Sam Varshavchik  <mrsam@courier-mta.com>

	* all: Major rewrite of rfc2045 parsing functions, adding an abstraction
	layer for reading the contents of the parsed rfc 2045 message, rather
	than reading from a plain file descriptor.

	* smap.c: New rfc2045src abstraction layer API update.

	* rfc822/rfc822_parsedt.c: Eliminate the dependency on ctype, replaced
	them with macros.

	* rfc822/rfc822hdr.c (rfc822hdr_namecmp): Factor out rfc822hdr_namecmp
	from rfc822hdr_is_addr, and make it usable, generically.

	* pop3dserver.c (main): "disableinsecurepop3" account option disables
	non-SSL logins.

	* imapd.c (chkdisabled): "disableinsecureimap" account option disables
	non-SSL logins.

	* rfc822/rfc2047u.c (rfc822_display_name): Semantical change --
	without an explicit name, display the address as the name. If the

	might invoke the ssl/tls cache call.  Free tls_info after
	SSL_CTX_free comes back.  Explicitly call SSL_CTX_flush_sessions to
	work around a bug in OpenSSL which blows away application data prior
	to calling SSL_CTX_flush_sessions in SSL_CTX_free().

	* libcouriertls:  By George, I think I've got it.  Implement

	shut down.

2000-11-23  Mr. Sam  <mrsam@courier-mta.com>

	* authenticate_auth.c: missing read_eol() breaks multiresponse SASL

        Fixed ENVELOPE to properly handle legacy RFC-822 group list
        notation.

1.2
	Authentication overhaul.  authdaemond split into alternate versions,
	one for each database back end.  The original "authdaemond" replaced
	by a shell script that checks for the installed authdaemond
	alternates, and run whatever's installed.  The idea is to allow
	LDAP and MySQL support to be separately packaged, and for LDAP and
	MySQL support to be added simply by installing the extra package
	(the base packaged for the garden variety and the LDAP/MySQL back
	end remains the same).  See NEWS for more information, as well
	as "Alternative authdaemond modules" section in INSTALL.

	"custom" authentication module - a stub for site-specific
	authentication code.

	Bundled POP3 server from the main Courier package.  The Courier-IMAP
	now includes a compatible POP3 server (by popular request).

	POP3 over SSL support is included.

	Added character sets windows-1250 through windows-1258.

	Added character sets IBM437, IBM775, IBM850, IBM852, IBM855, IBM857,
	IBM860 through IBM866, and IBM869.

	Optimized downloading of large attachments for Netscape Messenger.

1.1

     Use mysql_real_connect(), if available.

     Strip () from name of mail envelope sender that uses old-style header
     format, by calling rfc822_getname instead of rfc822_gettok.

     Reengineer couriertcpd locking mechanism, that permits SO_REUSEADDR.
     New locking mechanism uses liblock's daemon functions.  Removed
     --forcebind option, obsolete.  Added --stop and --restart to couriertcpd.

     standalone: new startup scripts.  Must manually stop the server if
     upgrading.

     Fix a minor interoperability issue with Linux, IMAP_MOVE_EXPUNGE_TO_TRASH,
     and sqwebmail (sqwebmail moves mail to trash by creating a hard link,
     when we expunge we attempt to rename the first link to the second one,
     in Linux rename() returns 0, but NOTHING happens).

     Bug fix -- bad BODYSTRUCTURE response when a multipart content-type
     does not have any sections.

     THREAD semantics updated to ietf-imapext-thread-03.

     THREAD REFERENCES bug fixes.

     Add unicode-based support for non-English character sets.

1.0  Performance tweaks.

     Spec file tweaked to build under RH 7.x

     IMAP_CHECK_ALL_FOLDERS option added.

     Implement IMAP SUBSCRIBE/UNSUBSCRIBE for private folders.

     More questions for the FAQ

     Reorder authentication modules.

     Subject stripping for THREAD and SORT updated to definition in
     draft-ietf-imapext-thread-02.txt ... Except for the broken part.  Should
     be interesting to see if someone spots the obvious glaring error, there.

     Experimental THREAD REFERENCES implementation.

     Fixed a bug in THREAD ORDEREDSUBJECT which skipped over messages without
     a subject header.

     Fixed a typo in IMAP_CAPABILITY -- should be THREAD= not THREAD-, oops.

0.99 SSL related bug fixes.

     Option to use IMAP STARTTLS instead of IMAP over SSL.

     Tweaks to the configuration for better detection of MySQL support.

0.36
     Berkeley DB 3 support.

     Complete rewrite of authmysql.  New authmysql module supports CRAM-MD5
     authentication.

     CHILDREN extension.  A compatibility switch for legacy behavior in order
     to keep Pine happy.

     Creation of debug file is now controlled entirely by IMAPDEBUGFILE.

     Replaced dependency on stunnel with couriertls.


0.35
     Remove spurious space in LIST response.

     IPv6 fixes.

     Fix bug that can be used to crash authdaemon with malformed CRAM-MD5
     authentication requests.


0.34
     Implemented THREAD and SORT extensions.

     Set ulimit for the spawned processes.

0.33a
     Various minor bug fixes in authentication code.  Many memory leaks
     plugged.  CRAM-MD5 with LDAP now works correctly.

0.33 Added IMAP_MOVE_EXPUNGE_TO_TRASH.

     Added IPv6 support.

     Bug fixes.

     IA-64 patches.

     Slightly changed semantics of maildir file creation.  Will abort on
     errors other than ENOENT.  DJB is wrong - if you keep looping
     you'll get stuck in an infinite loop if, say, directory permissions
     are wrong.  Don't loop on non-ENOENT errors.  Abort instead.

0.32 Added the authdaemon module.  Minor fixes for gnus and mutt related
     issues.  Global shared folders.

0.31 Added SSL support, via stunnel (tested with stunnel 3.8).
     Added a FAQ.
     Found and fixed a potential crash caused by messages with corrupted
     MIME headers.

0.29-30 mysql patch applied.  Fixed irrelevant typo in maildir_folderdir().
     authldap failed init bug fix.

     Fixed a bug that sent an incorrect terminating character if a partial
     fetch ended precisely in the middle of a CRLF boundary.

     Miscellaneous bug fixes in miscellaneous authentication modules.

     Added workaround for Netscape crash if it receives an attachment
     with a filename that contains backslashes.

     Added workaround for Pine's failure to quote userids and passwords
     that contain brackets.

0.28 Explicit check to block compilation as root.  Compile Courier-IMAP as
     non-root, then su to root before running make install.

0.27 A new configure option: --enable-workarounds-for-imap-client-bugs
     This enables a couple of workarounds for a bunch of stupid bugs in
     several IMAP clients.

     Nicholas Lee's vchkpw2userdb patch.

     Modified RPM build script.  authldap is not going to be explicitly
     suppressed.  If you have OpenLDAP client libraries installed, authldap
     authentication is going to be built and installed.  Remove authldap from
     imapd.config if you don't want it.

     Shared folder support (weeeeeeeeeee...).  Courier-IMAP will install a
     slightly modified maildirmake command, for that purpose, and a manual
     page.  Read the manual page.

     Added beta MySQL module.

     Kill all current sessions when the listener process stops.

     If the home directory has the sticky bit set, don't log in - maintenance
     lock.

0.26 Enhancements to authldap and authvchkpw - now links with the vpopmail
     library, so MySQL-based authentication is now supported!

0.25a More tweaks to authlib - Makefile + authvchkpw.  Fix bogus failure in
     make check in certain timezones.

0.25 A minor bug fix release.  Fixed a core dump in authldap.  Fixed some
     spurious make check failures in gdbmobj/bdbobj.  Other minor makefile
     and configure changes.  Major editing of INSTALL and README that will
     hopefully make them easier to understand.

0.24 Fixed several userdb bugs introduced in 0.23.  Oops.

0.23 Added experimental LDAP authentication support.  Don't set \Seen on
     fetch of RFC822.HEADER

0.22 authvchkpw fix.  Miscellaneous fixes for Outlook Express.  Other minor
     bug fixes.

0.21 Trying to fix problems that I think are caused by some cranky glibc/libc
     stdio implementations (seek errors, and such).  Refreshed userdb/authlib
     from RCS (changes fix bugs in code that Courier-IMAP never uses, but I
     like to keep things synced up).  Twiddled some docs.

     Added NAMESPACE capability.  This removed several configuration steps.

0.20 Additional enhancements to the authentication library -- implementation
     of framework to support additional SASL forms of authentication.
     Completed implementation of FETCH parameters that were left in a TO DO
     state.  Gave up, and made LIST=LSUB, for all intents and purposes.

0.19 Added CRAM-MD5 support.  Changed location of some installed files, in
     order to better comply with common GNU standards.  Take care when
     upgrading:

     prefix/lib is pretty much now renamed as prefix/libexec
     most stuff in prefix/bin is moved to prefix/sbin
     imapd.config is now installed in prefix/etc, instead of prefix/lib
     authentication modules are installed in prefix/libexec/authlib

     All the initialization and other scripts have been modified to look
     for files in new locations.

     Several bug fixes.

0.18 Many bug fixes for problems experienced on some systems due to type
     mismatches.
     Do not expunge on LOGOUT.
     Changed Red Hat RPMS to default to automatically start imapd on
     system bootup (previously, you had to manually edit imapd.config and flip
     the switch)

0.17 Potential tiny array overflow in redhat-crypt-md5.c, causing a failure
     in md5test.c.  Many configuration and portability changes.
     Intentionally omitted code that complained about some bad commands
     received from an IMAP client.  Certain IMAP clients sometimes send
     malformed commands, which we reject with an error, causing the client
     to complain.  Apparently some IMAP servers silently ignore this error.
     I may put this code back later.

0.16 Oops.  Typo fixed in the userdb script.

0.15 Removed AC_LANGCPLUSPLUS from some configure.in's.  They were giving
     some gccs some grief.  Fixed authvchkpw so that it actually works as
     advertised.

0.14 Initial release
