The new <tt>delete_mode</tt> and <tt>deletedprefix</tt> options in <tt>imapd.conf</tt> controls whether deletes are "immediate" or "delayed" and the mailbox hierarchy for "delayed" deletes. <i>-- courtesy of David Carter and FastMail.fm</i>.</li> <li>Fixed the special case of RENAMEing an Inbox, so that it doesn't keep the same mailbox uniqueid, thus allowing it to replicate properly (seen state is still preserved).</li> <li>Disabled <a href="http://en.wikipedia.org/wiki/Nagle's_algorithm">Nagle's algorithm</a> in <tt>sync_client</tt> and <tt>sync_server</tt> to increase the throughput of the replication protocol. <i>-- courtesy of Wes Craig</i>.</li> <li>Added support for a shared \Seen flag on messages (must be enabled on a per-mailbox basis with the <tt>/vendor/cmu/cyrus-imapd/sharedseen</tt> mailbox annotation.</li> <li>Added <tt>-g</tt> and <tt>-G</tt> options to <tt>reconstruct</tt> <i>-- courtesy of David Carter</i>.</li> <li>Added <tt>SETUIDVALIDITY</tt> command to the replication protocol <i>-- courtesy of David Carter</i>.</li> <li>Finally fixed (again?) alignment issues on 64-bit SPARC.</li> <li>Changed message GUIDs used by replication to be the SHA1 hash of the messages <i>-- based on work of David Carter and Fastmail.fm</i>.</li> <li>Improve the performance of commands that operate on sequence-sets. The sequence-set is now parsed only once, and the commands operate on a sorted list of seq-ranges.</li> <li>Added new <tt>cyr_synclog</tt> utility for adding events to the replication log <i>-- courtesy of Fastmail.fm</i>.</li> <li>Added support for PCRE library <i>-- courtesy of Fastmail.fm</i>.</li> <li>Added support for disabling duplicate delivery suppression on a per-folder basis with the <tt>/vendor/cmu/cyrus-imapd/duplicatedeliver</tt> mailbox annotation <i>-- courtesy of Fastmail.fm</i>.</li> <li>Fixed miscellaneous bugs and build issues.</li> </ul> <h1>Changes to the Cyrus IMAP Server since 2.3.8</h1> <ul> <li>Added support for BDB 4.5 and 4.6.</li> <li>Fixed bug in frontend handling of CREATE for both proxying and referring. <i>-- courtesy of Gary Mills</i></li> <li>Fixed local deletion during XFER from a unified server. <i>-- courtesy of Gary Mills</i></li> <li>Fixed XFER bug which prevented sieve scripts from being migrated. <i>-- courtesy of Gary Mills</i></li> <li>Allow utilities to be run as root (acquiring 'cyrus' uid on-the-fly).</li> <li>Changed the default value of the <tt>allowplaintext</tt> option to disabled (0).</li> <li>Finally fixed 64-bit alignment problem with HIGHESTMODSEQ.</li> <li>Fixed initialization of UUID subsystem for replication. <i>-- courtesy of Fastmail.fm</i></li> <li>Added <tt>-a</tt> option to <tt>cyr_expire</tt> to ignore to skip annotation check. <i>-- courtesy of Fastmail.fm</i></li> <li>Set the mtime of synchronized message files to INTERNALDATE (makes reconstruction a little friendlier). <i>-- courtesy of Fastmail.fm</i></li> <li>Fixed a bug in <tt>sync_client</tt> which caused it to bail when a message was deleted out from under it.</li> <li>Allow <tt>sync_server</tt> to accept unauthenticated connections from <tt>sync_client</tt> on a UNIX socket.</li> <li>Drastically reduced the amount of time it takes for a <tt>mupdate</tt> slave to synchronize with a master.</li> <li>Added URI contained in the <tt>Content-Location</tt> header to the <tt>BODYSTRUCTURE</tt> response (per RFC 3501). <i>-- inspired by Fastmail.fm</i></li> <li>Fixed <tt>flushseenstate</tt> bug which was causing unsolicited EXPUNGE responses during FETCH/STORE. <i>-- courtesy of David Carter</i></li> <li>Added option to <tt>ctl_mboxlist</tt> to verify the consistency of the mailbox list database and the spool partition(s).

A Murder no longer has to have discrete frontend and backend servers; any one "unified" server can both proxy and serve local mailboxes (proxy functionality in <tt>proxyd</tt> and <tt>lmtpproxyd</tt> has been merged with <tt>imapd</tt> and <tt>lmtpd</tt> respectively), or all "replicated" servers can serve the same mailboxes from a shared filesystem. The new <tt>mupdate_config</tt> option in <tt>imapd.conf</tt> is used to determine whether a Murder is using a "traditional", "unified" or "replicated" configuration.</li> <li>Ported/rewrote/integrated David Carter's mailspool replication code. <i>Development sponsored by Columbia University</i>.</li> <li>Added support for "delayed" expunge, in which messages are removed from the mailbox index at the time of the EXPUNGE (hiding them from the client), but the message files and cache entries are left behind, to be purged at a later time by <tt>cyr_expire</tt>. This reduces the amount of I/O that takes place at the time of EXPUNGE and should result in greater responsiveness for the client, especially when expunging a large number of messages. The new <tt>expunge_mode</tt> option in <tt>imapd.conf</tt> controls whether expunges are "immediate" or "delayed". <i>Development sponsored by FastMail</i>.</li> <li>Added support to place some/all mailbox metadata files (cyrus.* files) on a separate (probably high-speed) partition. See the new <tt>metapartition</tt> and <tt>metapartition_files</tt> options for details. <i>Development sponsored by FastMail</i>.</li> <li>Added support for accessing subfolders of INBOX via POP3. See the new <tt>popsubfolders</tt> option for details. <i>Development sponsored by FastMail</i>.</li> <li>Added support to <tt>lmtpd</tt> to do "fuzzy" mailbox matching on user+detail addresses. See the new <tt>lmtp_fuzzy_mailbox_match</tt> option for details. <i>Development sponsored by FastMail</i>.</li> <li>Added new <tt>sieve_extensions</tt> option to allow individual Sieve extensions to be enabled/disabled.</li> <li>The Sieve "include" extension is now supported. This also allows for global sieve scripts. See the new <tt>sieve_extensions</tt> options to enable it.</li> <li>The Sieve "body" extension is now supported. See the new <tt>sieve_extensions</tt> option to enable it. <i>Development sponsored by FastMail</i>.</li> <li>The $text$ variable for Sieve notify messages is now supported. <i>Development sponsored by FastMail</i>.</li> <li>The MIME structure of a new message destined for multiple recipients is now only parsed once rather than once per delivery, resulting in better performance. <i>Development sponsored by FastMail</i>.</li> <li>Support 64-bit quota usage (both per mailbox and for the entire quotaroot), based on a patch from Jeremy Rumpf. <i>Development sponsored by FastMail</i>.</li> <li>Added new <tt>flushseenstate</tt> option which causes imapd to immediately flush changes in \Seen state to disk rather than caching them until the mailbox is closed. Enabling this option may fix \Seen state weirdness with MS Outlook, at the expense of performance/scalability. <i>Based on a patch by John A. Tamplin (jtampli@sph.emory.edu).</i></li> <li>The Sieve "copy" extension is now supported.</li> <li>The IMAP "CATENATE" and "URLAUTH" extensions are now supported.</li> <li>Updated Sieve "vacation" extension to draft-ietf-sieve-vacation-04.</li> <li>Added support for Sieve scripts on shared mailboxes via the /vendor/cmu/cyrus-imapd/sieve annotation.</li> </ul> <h1>Changes to the Cyrus IMAP Server since 2.2.13</h1> <ul> <li><tt>ctl_mboxlist</tt> now dumps/undumps the mailbox type flags, making it useful for remote mailboxes.</li> <li>Added <tt>sieve_allowreferrals</tt> option to control whether <tt>timsieved</tt> issues referrals or proxys traffic to backends.</li> </ul> <h1>Changes to the Cyrus IMAP Server since 2.2.12</h1> <ul> <li>Allow sieve scripts to be run on shared mailboxes (via <tt>sieve</tt> annotation).</li> <li>Updated <tt>nntpd</tt> to be compliant with latest draft (soon to be RFC3977).</li> <li>Updated IMAP UIDPLUS extension to be compliant with latest specification (RFC4315).</li> <li>Performance improvements to <tt>quota</tt> utility.</li> <li>Fixed possible race condition in IMAP IDLE.</li> <li>Made <tt>ptloader</tt> runtime configurable.</li> <li>Added more extensive output to <tt>arbitron</tt>.</li> <li>Allow responses of any length from backend when proxing IMAP/POP3/NNTP traffic.</li> <li>Added <tt>plaintextloginalert</tt> option.</li> <li>Only allow <tt>mbpath</tt> to be run as Cyrus user.</li> <li>Added <tt>berkeley_hash</tt> and <tt>berkeley_hash_nosync</tt> cyrusdb backends (seem to perform better under heavy loads).</li> <li>Added <tt>lastpop</tt> mailbox annotation.</li> <li>Added subscribe/unsubscribe support to <tt>cyradm</tt>.</li> <li>Fixed miscellaneous bugs and build issues.</li> </ul> <h1>Changes to the Cyrus IMAP Server since 2.2.11</h1> <ul> <li>Revert index change which wasn't supposed to make it into 2.2.11</li> </ul> <h1>Changes to the Cyrus IMAP Server since 2.2.10</h1> <ul> <li>Fix possible single byte overflow in mailbox handling code.</li> <li>Fix possible single byte overflows in the imapd annotate extension.</li> <li>Fix stack buffer overflows in fetchnews (exploitable by peer news server), backend (exploitable by admin), and in imapd (exploitable by users though only on platforms where a filename may be larger than a mailbox name).</li> </ul> <h1>Changes to the Cyrus IMAP Server since 2.2.9</h1> <ul> <li>Fix 0 termination in mysasl_canon_user.</li> <li>Check for imap magic plus buffer overflow in proxyd also (CAN-2004-1015).</li> <li>Only send an over quota ALERT on SELECT if the quotaroot is different from the last ALERT, or we haven't sent an ALERT in over 10 min.</li> </ul> <h1>Changes to the Cyrus IMAP Server since 2.2.8</h1> <ul> <li>Change ACLs correctly when renaming a user</li> <li>Do not abandon std{in,out,err} file descriptors;

This will both ensure greater consistancy between the documentation and the code, as well as a more standard format for specifing service-specific configuration options in imapd.conf. Important changes are detailed here: <ul> <li> The tls_[service]_* configuration options have been removed. Now use [servicename]_tls_*, where servicename is the service identifier from cyrus.conf for that particular process.</li> <li> Administrative groups (e.g. admins and lmtp_admins) no longer union, service groups completely override the generic group. </li> <li> lmtp_allowplaintext is no longer a defined parameter and must be specified using the service name of your lmtp process if you require a specific value</li> </ul></li> <li> libcyrus has been split into libcyrus_min and libcyrus, so as to allow sensative applications (such as master) include the least amount of code necessary for operation </li> <li> Virtual domain support.

Now whenever there is a mailbox access, quota access, or subscription access, it goes through a hash function. this is done to help reduce the number of files/directories in any given directory.</li> <li>Added the binary <tt>mbpath</tt>. Given a mailbox name, this binary will print the filesystem path to that mailbox.

Sorry, but it had to happen. It now also includes a timing test (-z) which we use to test the SASL layers.</li> <li>imtest no longer uses a non-synchronizing literal with LOGIN, so it should work against all IMAP servers.</li> <li>The prot layer now uses SASL for encryption and authentication. This changed a large amount of code, and some build procedures.</li> <li>As a side effect of SASL, --enable-static-libraries now doesn't do anything. We are considering compiling cyrus with libtool to change this.</li> <li>Error codes returned by programs have changed, and programs return EX_TEMPFAIL far more than they used to. This is because Sendmail considers most not-EX_TEMPFAIL errors permanent; now, if it may not be permanent, EX_TEMPFAIL is returned. (See lib/exitcodes.h.)</li> <li>Two bugs fixed: UID FETCH's with no messages in range now return OK, not BAD. And an obscure bug in LIST case sensitivity is fixed.</li> </ul> <h2>Changes to the Cyrus IMAP Server Since Version 1.5.19</h2> <ul> <li>Most of the charset.c code (and mkchartable.c code) has been replaced thanks to John Myers).</li> <li>Bug fix in message.c to look up headers in the cache when they're in the cache correctly; thanks to Chris Newman for the fix.</li> <li>Code cleanup here and there (thanks to Bruce Balden).</li> <li>Annoying (and confusing) lines in syslog every time a message was delivered if deliver was compiled using dbm saying that deliver was "unable to fetch entry" have been removed.</li> <li>Content-Disposition lines were being parsed improperly. If they had no optional arguments, they were being ignored as if they were syntactically incorrect. This is fixed, but imapd will continue to serve wrong information unless cyrus.caches are rebuilt (with reconstruct) for any message that was added to the mailbox before this bug was fixed.</li> <li>The arbitron program now takes a mailbox pattern argument for the mailbox to run on. The manpage always said it did anyway.</li> <li>Uninitialized variable fixed in imapd.c with the shutdown file code.</li> <li>Minor tweaks to purify build config.</li> <li>Fix minor memory leak in proc.c where procfname wasn't being free'd.</li> <li>Fix brain fart in auth_krb_pts.c where a CLOSE() was done to a DB handle BEFORE we access the data read from the DB database. This means we were copying free'd memory into the groups list. Note this only affects people using DB, AFS and ptloader.</li> <li>Committed minor syslog log level changes in ptloader and deliver.</li> <li>make distclean now does what it's supposed to.</li> <li>Possibly misnamed experimental --enable-static-libraries switch that tries to do a good job of building binaries with whatever static libraries are availible. If you use this, you do so at your own risk, and if it fails, we will disavow all knowledge of you and your team. Good luck, Jim.</li> <li>Add optional third argument to imtest for it to take input from a file. This is a gross hack.</li> </ul> <h2>Changes to the Cyrus IMAP Server Since Version 1.5.14</h2> <ul> <li>LIST now honors the reference argument. <p>This behavior can be turned off by a configuration option imapd.conf--which may be desirable because of certain clients that ask for a "mail directory" setting for IMAP which will now cause problems when it was ignored before. (The default is for the reference argument to be honored.)</p> </li> <li>The <tt>arbitron</tt> program now takes a mailbox pattern argument for the mailbox to run on. The manpage always said it did anyway.</li> <li>Added --disable-server switch to optionally prevent compilation of server to help sites that just want client libraries (so cyradm and libcyrus can be compiled on remote systems without installing stuff into /usr/cyrus/bin, etc.) For now, the server is still configured in this case, and a Makefile is generated. This could change in future versions.</li> <li>Fixed a mmap leak in index.c in index_search_evaluate that caused problems on complex searches. Thanks to Jeff Schiller for pointing this out. Fixed a potential leak in mboxlist.c that happened if a rename went awry. Thanks to Chris Newman for pointing this out.</li> <li>Fixed a bug in LIST and LSUB code so that user.* mailboxes will be printed on every LIST instead of just the first one.</li> <li>Implemented the <i>POP3 Extension Mechanism</i>, RFC 2449, in order to advertise the capabilities already supported.</li> <li>Fixed a bug in mailbox.c that disallowed MUTF-7 representations of ASCII characters when it shouldn't have. (Thanks to John Myers for providing a fix and to Per Steinar Iversen for telling me that I didn't do it before.)</li> <li>More cleanup the ptloader/auth_krb_pts code. If you use Kerberos and IMSP, you *MUST* pick up cyrus-imspd-v1.5a6 (or newer).</li> <li>A few configure tweaks.</li> <li>Duplicate delivery changes: <ul> <li>Split out duplicate delivery elimination to multiple files. This should help reduce the lock contention that normally occurs with this file. To not clutter <i>config_dir</i>, the files will be located in a subdirectory named <tt>deliverdb</tt>, for example <tt>/var/imap/deliverdb</tt>. If you don't make this directory, nothing bad will happen (other than duplicate delivery elimination will not work).</li> <li>The time value is now stored as an integer in native byte order as opposed to converting it to a string before it is stored in the database.</li> <li>checkdelivered() now obtains a read lock instead of a write lock when trying to check for duplicates. Only markdelivered() grabs a write lock.</li> </ul> </li> <li>Added logic to cause cyradm to abort more cleanly if not given command line arguments in an interactive session. This gets rid of the dreaded <tt>application-specific intialization failed</tt> messages.</li> </ul> <h2>Changes to the Cyrus IMAP Server Since Version 1.5.11</h2> <ul> <li>The CREATE command now ignores a trailing hierarchy delimiter instead of ignoring the CREATE command.</li> <li>UIDPLUS is now always advertised in CAPABILITY and is always availible. The UIDPLUS extension is a set of optimizations using UID values instead of sequence numbers and is described in RFC 2359.</li> <li>Cyrus no longer rejects messages with 8-bit characters in the headers. Rather than reject the message, characters with the 8th bit set are changed to 'X'. Internationalization in headers is supported by the mechanism specified in RFC 2047 (and RFC 1342).</li> </ul> <h2>Changes to the Cyrus IMAP Server Since Version 1.5.10</h2> <ul> <li>If ENABLE_EXPERIMENT is set, the server no longer claims to support OPTIMIZE-1; instead, it claims to support UIDPLUS. The Getuids command has been removed since it is not in the UIDPLUS document (draft-myers-imap-optimize-03.txt).</li> <li>The checks for Tcl in configure are much smarter. The configure script asks tclsh where its configuration lives, then consults the shell scripts that have that information. This should work with 7.5 or better, which is what the server requires anyway. (All the previous checks to look for Tcl libraries are gone; now, configure runs tclsh and asks it where the Tcl libraries are, then runs the shell scripts that are in that directory. Since the tclConfig.sh script may not be in that directory, it looks in .. as well.)</li> <li>The checks for com_err in configure are a little smarter and look to see if all the pieces are there before trying to use them.</li> <li>Added support for the NAMESPACE extension (if --enable-experiment is supplied).</li> <li>Added a "reject8bit" switch to imapd.conf. If set to "true", messages containing 8-bit-set characters in the headers are rejected (the previous behavior); if set to "false" or left to the default value, messages containing 8-bit-set characters have these characters changed to a constant character ('X').</li> <li>Added the "fud" program. This is an interm hack designed to allow allow finger information to be retrieved for cyrus users. This is experimental and it is not recommend that services be built arround this feature, since it is likely to be removed in a future release of the IMAP server.</li> <li>Bug fix: User defined flags now work properly.</li> </ul> <h2>Changes to the Cyrus IMAP Server Since Version 1.5.2</h2> <ul> <li>Fixed a bug with word alignment on Solaris using Kerberos compiled with Sun's CC. (Several patches were submitted; thanks to everyone who did so.)</li> <li>Patches from John Myers, including more glob fixes.</li> <li>Use the default hash function from DB. Note that this means that the existing <tt>delivered.db</tt> and <tt>ptscache.db</tt> is <b>NOT</b> compatible with this release. These files should be removed.</li> <li>Provide two debugging programs that dump the databases: <tt>ptdump</tt> and <tt>dump_deliverdb</tt>.</li> <li>Multiple changes to ptloader. added a bunch of flags; let it reauthenticate on its own; added support perl wrapper; added bunch of debugging information/output; bunch of other cleanups</li> <li>The mailboxes file is now closed if it isn't likely to be referenced, hopefully preventing old mailboxes files from hanging around in memory as frequently.</li> <li>Added a patch from Eric Hagberg to work around a possible deadlock condition in mboxlist.c where rename isn't atomic.</li> <li>Patch from John Myers to get rid of cyrus.seen corruption in bsearch_mem.</li> <li>Patch from John Myers and to allow ISO-8859-1 characters in mailbox names.</li> <li>Makedepend still runs, and still generates warnings, but these are squirrled away in makedepend.log.</li> <li>On mailbox delete, the server will no longer try and unlink ".." and "." as we got a report that it seriously breaks one file system (even as non-root).</li> <li>Added some support for Netscape's very misleading "Administrate My Mail" menu option in Communicator. Allows for a URL to be set in imapd.conf for the page to refer users to; needs to be turned on with --enable-netscapehack at compile time to enable it.</li> <li>Bug swap: imtest quotes password with a non-synchronizing literal in order to allow weird characters like ) in passwords. But it doesn't look to see if the server supports non-synchronizing literals.</li> <li>If the file "<tt>msg/motd</tt>" exists, the first line is now sent to clients upon login.</li> <li>Bug fix: to handle BODY[] properly when fetching news articles (truncation no longer occurs). (thanks to John Prevost)</li> <li>The makedepend supplied should now run on Solaris Intel. (thanks to Chris Newman)</li> <li>Added some hacks to pwcheck.c for Linux and Digital Unix where the default protections on the socket don't allow the cyrus user to read it. (thanks to Lyndon Nerenberg)</li> <li>Bug fix: Flags beginning with \ are system flags and users can only create the defined flags. The code to do this before was confused.</li> <li>The configure scripts and makefiles have some random fixes.</li> <li>Added a contrib directory for reasons of laziness in collecting patches, not all of which should be in the distribution.</li> <li>ptloader can now renew its AFS authentication by reading from a srvtab file.</li> <li>The configure script now looks for a libcom_err and can use an installed one if one exists.</li> <li>Other small bug fixes.</li> </ul> <h2>Changes to the Cyrus IMAP Server Since Version 1.5</h2> <ul> <li>Bug fix: RENAME corrupted mailboxes if they had been EXPUNGEd.

This will be fixed in a subsequent release.</li> <li>Bug fix: imclient_autenticate now does resolution on the hostname before authenticating to it. This caused problems when authenticating to an address that was a CNAME.</li> <li>Bug fix: LIST %.% (and other multiple hierarchy delimiter matches) works properly. Several other glob.c fixes are included as well.</li> <li>Bug fix: a fetch of exclusively BODY[HEADER.FIELDS...] should now work properly.</li> <li>Bug fix: reconstruct now considers a nonexistant INN news directory to be empty; this makes reconstruct fix the cyrus.* files in the imap news partition.</li> <li>Added a manpage for imclient.</li> <li>Fixed a few other minor bugs.</li> </ul> <h2>Changes to the Cyrus IMAP Server Since Version 1.4</h2> <ul> <li>Implemented the "<tt>IMAP4rev1</tt>" protocol commands. (The hierarchical behavior of RENAME, which was added late to the IMAP4rev1 specification, is not implemented.)

It's not quite as bad as HPUX, but...</li> <li>Bug fix: in imclient.c, don't free NULL pointers and don't call htons() on the output of getservbyname(). Have to abort sending the command if you get a tagged response when sending a literal.</li> <li>The auth_xxx routines now create/take a state argument instead of maintaining internal static state.</li> <li>Solaris mktime() is buggy in some releases. Create and use mkgmtime() for parsing date strings.</li> <li>Message parsing routines now use memory mapping, though they still copy data around in line-sized buffers.</li> </ul> <h2>Changes to the Cyrus IMAP Server Since Version 1.3</h2> <ul> <li>Implemented the "<tt>reconstruct -m</tt>" command, for reconstructing the <tt>mailboxes</tt> file. <b>IMPORTANT:</b> it is necessary to run the command "<tt>reconstruct -m</tt>" as the cyrus user after upgrading the Cyrus IMAP software from version 1.3 or earlier. We recommend you make a backup copy of the <tt>mailboxes</tt> file in the configuration directory before performing the conversion.</li> <li>Mailbox names are now case sensitive, not case insensitive. "<tt>INBOX</tt>" is the exception, and is treated as being case-insensitive.</li> <li>Personal mailboxes now appear to their owners as being under the "<tt>INBOX.</tt>" hierarchy. For example, the mailbox "<tt>user.bovik.work</tt>" appears to the user "<tt>bovik</tt>" as "<tt>INBOX.work</tt>". The user may still refer to the mailbox with the name "<tt>user.bovik.work</tt>".</li> <li>Previously, the code used "<tt>anybody</tt>" as the name of the group that all users are in, but the documentation used the name "<tt>anyone</tt>". Changed the code to match the documentation. The name "<tt>anybody</tt>" will be canonicalized to the name "<tt>anyone</tt>".</li> <li>The install document now gives different recommended locations for the server databases. The recommended location of the configuration directory changed from "<tt>/usr/cyrus</tt>" to "<tt>/var/imap</tt>" and the recommended location of the default partition directory changed from "<tt>/usr/spool/cyrus</tt>" to "<tt>/var/spool/imap</tt>". It is <b>NOT</b> necessary to change the locations of these directories when upgrading from version 1.3 or earlier of the Cyrus IMAP server software. If you do wish to change the locations of these directories to match the new recommendations, simply rename the directories and change the appropriate values in your <tt>/etc/imapd.conf</tt> file.</li> <li>Created a "<tt>make install</tt>" rule. See the <a href="install.html">installation</a> document for all the new corresponding <tt>configure</tt> options. Note the recommended location of the "<tt>imapd</tt>", "<tt>pop3d</tt>", and "<tt>deliver</tt>" programs has changed, this change needs to be reflected in the "<tt>inetd.conf</tt>" and "<tt>sendmail.cf</tt>" files.</li> <li>New "<tt>login_unix_pwcheck</tt>" module and "<tt>pwcheck</tt>" daemon, for improved shadow password support. See the "<tt>pwcheck/README.pwcheck</tt>" file in the distribution for details.</li> <li>Renamed the "<tt>login_unix_shadow</tt>" module to "<tt>login_unix_getspnam</tt>".</li> <li>Added a mail notification mechanism, using Zephyr.</li> <li>Added a feature to automatically create user IMAP accounts. Controlled by the "<tt>autocreatequota</tt>" config option.</li> <li>Added the "<tt>logtimestamps</tt>" config option, for putting timestamp information into protocol telemetry logs.</li> <li>Beefed up the Kerberos checks in Configure to ensure the DES library routines exist.</li> <li>On some systems, the "<tt>echo</tt>" command with no arguments emits a newline. Changed the installation document to instead use the "<tt>true</tt>" command to create the "<tt>mailboxes</tt>" file.</li> <li>Store a redundant copy of a mailbox's ACL in the <tt>cyrus.header</tt> file, so "<tt>reconstruct -m</tt>" may later use it as a backup.</li> <li>Had to remove the declaration of <tt>tcl_RcFileName</tt> for the latest version of Tcl.</li> <li>Make much more extensive use of memory mapping. Replace the binary search module with one that searches a memory mapped area.</li> <li>Replaced the yacc-based RFC822 address parser with a hand-coded one.</li> <li>Replaced the et (error table) libary with a version that doesn't require lex or yacc. Remove the lex/yacc checking from Configure.</li> <li>Safety feature: most programs now refuse to run as root.</li> <li>Bug fix: Issue [TRYCREATE] tag on COPY command when appropriate.</li> <li>Bug fix: The quoted-printable decoder wasn't ignoring trailing whitespace, as required by MIME.</li> <li>Bug fix: Don't spew cascade errors if the server gets an EOF during/after reading an APPEND literal.</li> <li>Bug fix: gmtmoff_gmtime.c was returning results with the wrong sign.</li> <li>Bug fix: imclient_send was appending spaces to %d and %u and the response parser was not handling responses that did not contain a space after the keyword.</li> <li>Bug fix: rmnews wasn't removing some (un-indexed) article files correctly.</li> <li>Completely disabled the dropoff code for now.
