1.0.rc10 released
by Timo Sirainen 16 Oct '06

16 Oct '06

http://dovecot.org/releases/dovecot-1.0.rc10.tar.gz http://dovecot.org/releases/dovecot-1.0.rc10.tar.gz.sig I've finally read all the mails in the mailing list and in my INBOX. If I haven't replied to some of your mail, please resend it. Remember that since 1.0.rc9 release dovecot.index.cache files will get rebuilt in 64bit systems, and it's probably better to delete them manually so you don't get errors in log files. There are only a couple of issues left in my v1.0-TODO list: - Master process appears to be leaking log fds with kqueue. Could someone again give me access to a system where this happens? - Login process problems. How well does it work now? Hopefully well enough that v1.0 could be released. - LDAP authentication is leaking memory? Can anyone confirm this? Even better, can someone figure out what exactly is leaking? :) Not a v1.0 blocker though. I think v1.0 will be released once no-one has reported any major problems for a Dovecot release in 2-4 weeks. I think login process handling is the only potentially major problem left. There are a few patches from people that I haven't forgotten, but I've decided not to put them into v1.0 anymore: - Filesystem quota group. I don't think it's that important feature, and it might break something. - HFS+ hardlink avoiding - Managesieve - vmailmgr support And finally the changes in this release: * When matching allowed_nets IPs, convert IPv6-mapped-IPv4 addresses to actual IPv4 addresses first. + IMAP: Try to avoid sending duplicate/useless message flag updates + Added support for non-plaintext authentication for vpopmail if it returns plaintext passwords. Based on patch by Remi Gacogne. + Added %D modified to return "sub.domain.org" as "sub,dc=domain,dc=org" (for LDAP queries). Patch by Andrey Panin. - rc9 broke cache files in 64bit systems - deliver works now with mail_chroot - auth cache didn't work properly with multiple passdbs - Fixes to handling CRLF linefeeds in mboxes.

1.0.rc9 released
by Timo Sirainen 14 Oct '06

14 Oct '06

http://dovecot.org/releases/dovecot-1.0.rc9.tar.gz http://dovecot.org/releases/dovecot-1.0.rc9.tar.gz.sig Most importantly this should fix the login process problems that people have been reporting. There were also some bugs in the proxying feature. Also note the 64bit change in dovecot.index.cache files. Unless you delete dovecot.index.cache files manually, you'll these kind of error messages into your logs: Error: Corrupted index cache file ...dovecot.index.cache: registered field date.sent size changed They'll get fixed automatically of course, but it might be a bit annoying to see them. * 64bit systems: dovecot.index.cache file will be rebuilt because some time fields have been changed from 64bit fields to 32bit fields. Now the same cache file can be used in both 32bit and 64bit systems without it being rebuilt. * Added libmysqlclient workaround to conflicting sha1_result symbol, which caused Dovecot to fail logging into MySQL. + dovecot.index.cache file opening is delayed until it's actually needed. This reduces disk accesses a bit with eg. STATUS commands. + auth_cache: Try to handle changing passwords automatically: If password verification fails, but the last one had succeeded, don't use the cache. This works only with plaintext auth. - dovecot.index.cache: We didn't properly detect if some fields were different length than we expected, which caused assert crashes - Lots of fixes to login/master process handling - mbox: Fixed a bug causing "X-IMAPbase uid-last unexpectedly lost in mbox file" errors, and possibly others.

1.0.rc8 released
by Timo Sirainen 09 Oct '06

09 Oct '06

I've still over 200 mails unread in the mailing list, and important things left in TODO. This release is an improvement over rc7 anyway, hopefully I'll have time to fix the rest soon. http://dovecot.org/releases/dovecot-1.0.rc8.tar.gz http://dovecot.org/releases/dovecot-1.0.rc8.tar.gz.sig * GSSAPI: Changed POP3 service name to "pop", which is what the standard says * "mbox:/var/mail/%u" no longer works as the mail location. You'll have to specify the mail root explicitly, just like the examples always have: "mbox:~/mail:INBOX=/var/mail/%u" + SHA1, LDAP-MD5, PLAIN-MD5, PLAIN-MD4: The password can be now either hex or base64 encoded. The encoding is detected automatically based on the password string length. + Allow running only Dovecot master and dovecot-auth processes with protocols=none setting + deliver: -f <envelope sender> parameter can be used to set mbox From_-line's sender address + deliver: Log all mail saves and failures + Tru64 SIA passdb support. Patch by Simon L Jackson. - INBOX was listed twice in mailbox list if namespace prefix was used - INBOX-prefixed namespaces were a bit broken - kqueue: Fix 100% CPU usage - deliver: Duplicate storage was a bit broken - dictionary code was broken (ie. dict quota) - SIGHUP caused crashes sometimes

1.0 RC7 released
by Timo Sirainen 18 Aug '06

18 Aug '06

http://dovecot.org/releases/dovecot-1.0.rc7.tar.gz http://dovecot.org/releases/dovecot-1.0.rc7.tar.gz.sig Can everyone now agree that there are no more hangs? :) * Require that Dovecot master process's version number matches the child process's, unless version_ignore=yes. Usually it's an accidental installation problem if the version numbers don't match. * Maildir: Create maildirfolder file when creating new maildirs. + ldap+prefetch: Use global uid/gid settings if LDAP query doesn't return them + %variables: Negative offsets count from the end of the string. Patch by Johannes Berg. - kqueue ioloop code rewrite - notify=kqueue might have caused connection hangs sometimes - deliver: If message body contained a valid mbox From_ line, it and the rest of the message was skipped. - mbox: We got into infinite loops if trying to open a 2 byte sized file as mbox. - Don't crash with ssl_disable=yes - quota plugin caused compiling problems with some OSes - mbox: After saving a mail to a synced mbox, we lost the sync which caused worse performance I think my v1.0 TODO list is: - avoid duplicate flag change notifications, or in case the message is also expunged don't bother notifying its flag changes at all (shouldn't be hard) - HFS+ avoid-hardlinks patch? - 32bit -> 64bit upgrade still doesn't work without assert-crashing: mail-cache-transaction.c: line 709 (mail_cache_add): assertion failed: (fixed_size == (unsigned int)-1 || fixed_size == data_size) - Courier-compatible INBOX. namespace gives "invalid namespace" errors I'm still not sure about the last one though. Could someone give me specific commands that clients send that causes it? As for the 32bit -> 64bit upgrade fix, could someone give me access to a x86-64 machine for a while to test it out?

1.0 RC6 released
by Timo Sirainen 07 Aug '06

07 Aug '06

http://dovecot.org/releases/dovecot-1.0.rc6.tar.gz http://dovecot.org/releases/dovecot-1.0.rc6.tar.gz.sig Back to rc1's SSL proxying code with some improvements, which hopefully now makes everyone happy. I'm seeing all kinds of problems with namespace prefixes and LIST code. I guess it would be important to fix it before v1.0 since it makes upgrades from other servers easier.. I also tried looking into the "Unknown namespace" problems that happens if you try to create only one namespace with "INBOX." prefix. I couldn't really figure out what causes those errors. Could someone show me what commands the client tries to use which causes it? * Removed login_max_logging_users setting since it was somewhat weird in how it worked. Added login_max_connections to replace it with login_process_per_connection=no, and with =yes its functionality is now within login_max_processes_count. + Added --with-linux-quota configure option to specify which Linux quota version to use, in case it's not correct in sys/quota.h. Usually used as --with-linux-quota=2 + acl plugins: If .DEFAULT file exists in global ACL root directory, use it as the default ACLs for all mailboxes. - Fixes to login process handling, especially with login_process_per_connection=no. - Back to the original SSL proxy code but with one small fix, which hopefully fixes the occational hangs with it - Several fixes to handling LIST command more correctly.

http://dovecot.org/releases/dovecot-1.0.rc5.tar.gz http://dovecot.org/releases/dovecot-1.0.rc5.tar.gz.sig Hopefully this is the final mbox bugfix.. Nothing else changed since rc4.

http://dovecot.org/releases/dovecot-1.0.rc4.tar.gz http://dovecot.org/releases/dovecot-1.0.rc4.tar.gz.sig Just one fix since RC3: - Saving to mboxes caused assert-crashes

1.0 RC3 released

02 Aug '06

http://dovecot.org/releases/dovecot-1.0.rc3.tar.gz http://dovecot.org/releases/dovecot-1.0.rc3.tar.gz.sig Does this fix the hangs people have been reporting? - SSL connections hanged sometimes, especially when saving messages. - mbox: Mail bodies were saved with CR+LF linefeeds - Mail forwarding was broken with deliver/Sieve - dbox fixes. Might actually be usable now. - Index file handling fixes with keywords - Cache file was incorrectly used in some situations, which probably caused problems sometimes. - Maildir++ quota: Don't count "." and ".." directory sizes to quota. After rewriting maildirsize file keep its fd open so that we can later update it. Patch by Alexander Zagrebin

1.0.rc2 released
by Timo Sirainen 04 Jul '06

04 Jul '06

Final 1.0 release is looking to get closer. There's nothing left in my TODO list for it, so please report any old and new bugs you see. This release also makes upgrades from 0.99 more transparent with automatic renaming of .subscriptions and .customflags files with maildir. http://dovecot.org/releases/dovecot-1.0.rc2.tar.gz http://dovecot.org/releases/dovecot-1.0.rc2.tar.gz.sig * disable_plaintext_auth=yes: Removed hardcoded 127.* and ::1 IP checks. Now we just assume that the connection is secure if the local IP matches the remote IP address. * SSL code rewrite which hopefully makes it work better than before. Seems to work correctly, but if you suddently have trouble with SSL connections this is likely the reason. + verbose_ssl=yes: Log also SSL alerts and BIO errors - If namespace's location field wasn't set, the default location was supposed to be used but it wasn't. - When copying ssl-parameters.dat file from /var/lib to /var/run its permissions went wrong if it couldn't be copied with hard linking. - Fixed filesystem quota plugin to work with BSDs. - Maildir: Saving mails didn't work if quota plugin was enabled (again) - Maildir: Messages' received time wasn't saved properly when saving/copying multiple messages at a time. Also if using quota plugin the S= size was only set for the first saved file, and even that was wrong. - passdb passwd-file: Don't require valid uid/gid fields if file isn't also being used as a userdb. - PostgreSQL: Handle failures better so that there won't be "invalid fd" errors in logs. - Don't try to expunge messages if the mailbox is read-only. It'll just cause our index files to go out of sync with the real mailbox and cause errors. - ANONYMOUS authentication mechanism couldn't work because anonymous_username setting wasn't passed from master process.

1.0.rc1 released
by Timo Sirainen 28 Jun '06

28 Jun '06

I think the code is now stable enough to be called the first release candidate. Please report any bugs, new and old. The filesystem quota numbers should be correct now? http://dovecot.org/releases/dovecot-1.0.rc1.tar.gz http://dovecot.org/releases/dovecot-1.0.rc1.tar.gz.sig * PAM: If user's password is expired, give "Password expired" error message to the user. Now actually working thanks to Vaidas Pilkauskas * Relicensed dovecot-auth, lib-sql and lib-ntlm to MIT license. See COPYING file for more information. * Abuse prevention: When creating a mailbox, limit the number of hierarchies (up to 20) and the length of the mailbox name within a hierarchy (up to 200 characters). * mbox: If saved mail doesn't end with LF, add it ourself so that the mails always have one empty line before the next From-line. + Added --with-statedir configure option which defaults to $localstatedir/lib/dovecot. ssl-parameters.dat is permanently stored in that directory and is copied to login_dirs from there. + IMAP: Support SASL-IR extension (SASL initial response) + Support initial SASL response with LOGIN mechanism. Patch by Anders Karlsson + Added PLAIN-MD4 password scheme. Patch by Andrey Panin. + Added support for XFS disk quotas. Patch by Pawel Jarosz + If another process deletes the opened mailbox, try to handle it without writing errors to log file. Handles the most common cases. + Added TLS support for LDAP if the library supports it. - SEARCH command was more or less broken with OR and NOT conditions - Dovecot corrupted mbox files which had CR+LF linefeeds in headers - MySQL code could have crashed while escaping strings - MD4 code with NTLM authentication was broken with 64bit systems. Patch by Andrey Panin - Plugin loading was broken in some OSes (eg. FreeBSD) - Several fixes to handling empty values in configuration file - Several fixes to dictionary quota backend and dict server. Also changed how they're configured. - deliver: Fixed plugin handling settings - mbox_min_index_size handling was somewhat broken - passdb passwd-file: extra_args field wasn't read unless the file was also used as userdb.
