v1.0.3 released
by Timo Sirainen 01 Aug '07

01 Aug '07

http://dovecot.org/releases/1.0/dovecot-1.0.3.tar.gz http://dovecot.org/releases/1.0/dovecot-1.0.3.tar.gz.sig - deliver: v1.0.2's bounce fix caused message to be always saved to INBOX even if Sieve script had discard, reject or redirect commands. - LDAP: auth_bind=yes and empty auth_bind_userdn leaked memory - ACL plugin: If user was given i (insert) right for a mailbox, but not all s/t/w (seen, deleted, other flags) rights, COPY and APPEND commands weren't supposed to allow saving those flags. This is technically a security fix, but it's unlikely this caused problems for anyone. - ACL plugin: i (insert) right didn't work unless user was also given l (lookup) right. - Solaris: Fixed filesystem quota for autofs mounts.

v1.1.alpha1 released
by Timo Sirainen 19 Jul '07

19 Jul '07

http://dovecot.org/releases/1.1/alpha/dovecot-1.1.alpha1.tar.gz http://dovecot.org/releases/1.1/alpha/dovecot-1.1.alpha1.tar.gz.sig This is the first alpha release of Dovecot v1.1. I hope that it stabilizes into final release within a few months. There are a lot of new features since v1.0. The most important ones are listed at the end of this post. This is the only v1.1.alpha announcement I send to dovecot-news list (or to www.dovecot.org news). The next one probably will be v1.1.rc1. I've been stress testing the code a lot and I've also been using it myself for almost a year, so I think this release should actually be quite stable and usable. But since I haven't tested everything, there might be some crashes and misbehaving commands. So this release should now have all the major features that I intend to add to v1.1 (except for dbox rewrite, see below). Some smaller features will still be added. The rest of the major features in my previous v1.1 list will go to v1.2. While v1.1 is getting stabilized I'm beginning to rewrite dbox code. Its code is isolated from the rest of Dovecot, so it can't destabilize anything else. Hopefully it will be ready before v1.1 release, although maybe still marked as experimental. Some of the features might not be considered quite ready yet: - Mailbox list indexes improve STATUS performance a lot (maybe 7x) when mailboxes haven't changed. Handling updates however is a lot slower than I'd want (2x with one client, more with multiple), so you may want to disable them with mailbox_list_index_disable=yes until the update performance gets better. - THREAD code is completely rewritten with support for incremental updates and index files. I tested it last year and it seemed OK, but I didn't dare try it now so I wouldn't have to delay this alpha if it was broken :) I'll do some more testing soon, but for now be careful with using v1.1 with webmails. - SORT code also uses indexes now, but it's a lot simpler so it probably works. - Squat indexes work and I'm using them myself, but they'll be rewritten for v1.2 with a new faster format. - Although Dovecot now flushes NFS attribute/data caches when needed, I'm not sure if it's done in all the necessary places. - I don't remember if I've tested expire plugin at all. So, the largest changes I've added to NEWS file (which BTW won't contain changes between alphas/betas/rcs, those will be only in my mailing list posts): * After Dovecot v1.1 has modified index or dovecot-uidlist files, they can't be opened anymore with Dovecot versions earlier than v1.0.2. * Empty passwords in passdb doesn't allow user to log in with any password anymore. To do that you'll also need to set nopassword extra field. + IMAP: Added support for UIDPLUS and LIST-EXTENDED extensions. + IMAP SORT: Sort keys are indexed, which makes SORT commands faster. + IMAP THREAD: Threads are indexed into a dovecot.index.thread file. It can usually be updated incrementally, so this makes THREAD fast. + Added Dovecot-specific X-REFERENCES2 threading algorithm. It's similar to REFERENCES, but it doesn't do base subject merging and it sorts the threads by their newest message. + When saving messages, update cache file immediately with the data that we expect client to fetch later. Maildir-only currently. + NFS attribute and data caches are are flushed whenever needed. See mail_nfs_storage and mail_nfs_index settings. + Mailbox list indexes. Mailbox metadata is stored there, so STATUS commands can return synchronized mailboxes' metadata simply by reading a single mailbox list index file. Currently works only with Maildir++ layout. + Out of order command execution (SEARCH, FETCH, LIST), nonstandard command cancellation (X-CANCEL <tag>) + Expire plugin can be used to keep track of oldest messages in specific mailboxes. A nightly run can then quickly expunge old messages from the mailboxes that have them. The tracking is done using lib-dict, so you can use either Berkeley DB or SQL database. + Namespaces are supported everywhere now. + Full text search indexing support with Lucene and Squat backends. + OTP and S/KEY authentication mechanisms (by Andrey Panin). + mbox and Maildir works with both Maildir++ and FS layouts. You can change these by appending :LAYOUT=maildir++ or :LAYOUT=fs to mail_location. + LDAP: Support templates in pass_attrs and user_attrs + Support for listening in multiple IPs/ports. + Quota plugin rewrite: Support for multiple quota roots, warnings, allow giving storage size in bytes or kilo/mega/giga/terabytes, per-mailbox quota rules.

v1.0.2 released
by Timo Sirainen 15 Jul '07

15 Jul '07

http://dovecot.org/releases/dovecot-1.0.2.tar.gz http://dovecot.org/releases/dovecot-1.0.2.tar.gz.sig Fixes several bugs. This release also adds compatibility with upcoming Dovecot v1.1 so it'll be possible to upgrade to v1.1 and back to v1.0.2 without anything breaking. * dbox isn't built anymore by default. It will be redesigned so it shouldn't be used. + Maildir: Support reading dovecot-uidlist (v3) files created by Dovecot v1.1. - Maildir: "UIDVALIDITY changed" errors could happen with newly created mailboxes - If "INBOX." namespace was used, LIST returned it with \HasNoChildren which caused some clients not to show any other mailboxes. - Maildir++ quota: If multiple processes were updating maildirsize at the same time, we failed with "Unknown error". - IMAP: IDLE didn't actually disconnect client after 30 minutes of inactivity. - LDAP passdb/userdb was leaking memory - deliver: %variables in plugin {} weren't expanded - deliver: Don't bounce the mail if Sieve plugin returns failure

v1.0.1 released
by Timo Sirainen 15 Jun '07

15 Jun '07

http://dovecot.org/releases/dovecot-1.0.1.tar.gz http://dovecot.org/releases/dovecot-1.0.1.tar.gz.sig Lots of small fixes. * deliver: If Return-Path doesn't contain user and domain, don't try to bounce the mail (this is how it was supposed to work earlier too) * deliver: %variables in mail setting coming from userdb aren't expanded anymore (again how it should have worked). The expansion could have caused problems if paths contained any '%' characters. + Print Dovecot version number with dovecot -n and -a + deliver: Added -e parameter to write rejection error to stderr and exit with EX_NOPERM instead of sending the rejection by executing sendmail. + dovecot --log-error logs now a warning, an error and a fatal - Trying to start Dovecot while it's already running doesn't anymore wipe out login_dir and break the running Dovecot. - maildir: Fixed "UID larger than next_uid" errors which happened sometimes when dovecot-uidlist file didn't exist but index files did (usually because mailbox didn't have any messages when it was selected for the first time) - maildir: We violated maildir spec a bit by not having keyword characters sorted in the filename. - maildir: If we don't have write access to cur/ directory, treat the mailbox as read-only. This fixes some internal error problems with trying to use read-only maildirs. - maildir: Deleting a symlinked maildir failed with internal error. - mbox: pop3_uidl_format=%m wasn't working right - mbox: If non-filesystem quota was enabled, we could have failed with "Unexpectedly lost From-line" errors while saving new messages - mysql auth: %c didn't work. Patch by Andrey Panin - APPEND / SEARCH: If internaldate was outside valid value for time_t, we returned BAD error for APPEND and SEARCH never matched. With 64bit systems this shouldn't have happened. With 32bit systems the valid range is usually for years 1902..2037. - COPY: We sent "Hang in there.." too early sometimes and checked it too often (didn't break anything, but was slower than needed). - deliver: Postfix's sendmail binary wasn't working with mail_debug=yes - Don't corrupt ssl-parameters.dat files when running multiple Dovecot instances. - Cache compression caused dovecot.index.cache to be completely deleted with big endian CPUs if 64bit file offsets were used (default) - Fixed "(index_mail_parse_header): assertion failed" crash

CVS to Mercurial switch
by Timo Sirainen 19 May '07

19 May '07

I've been meaning to switch away from CVS for a few years now, but I was never sure what I wanted to switch to, so I kept delaying it. I finally decided yesterday that Mercurial is pretty nice. The Mercurial repository is available from http://hg.dovecot.org/ (has a nice web interface). I wrote a small Mercurial mini-howto below. I'm not a Mercurial expert yet, so if you know better ways to do some things please let me know. The CVS repositories will still exist for a while, but they won't be updated anymore. If you notice the CVS being referenced somewhere (wiki, docs, etc.) please let me know (or fix yourself in wiki). 1. Fetch the initial repository: - ex. CVS HEAD: hg clone http://hg.dovecot.org/dovecot/ - ex. branch_1_0: hg clone http://hg.dovecot.org/dovecot-1.0/ - sieve plugin: hg clone http://hg.dovecot.org/dovecot-sieve-1.0/ The Sieve plugin currently works only with v1.0. I'll make a new "dovecot-sieve" repository for CVS HEAD later. 2. Update the repository: hg pull hg merge # only needed if you had done any changes hg update # to actually see the pulled changes All of this can be done with fetch extension. You can enable it by adding to ~/.hgrc: [extensions] hgext.fetch = After that you can use "hg fetch" which does all the above 3 commands (as far as I know, haven't really tried yet). 3. If you want to modify the sources, add your name to ~/.hgrc so it goes nicely into changelogs: [ui] username = Timo Sirainen <tss(a)iki.fi> You're able to "hg commit" your own changes into your repository. If you want to publish them, use "hg log" to see the changeset ID, and then use "hg export changesetid" to get patch ("hg export tip" might work too if you just want the last change(?)). You can then email the patch to Dovecot mailing list to get it merged. With CVS the ChangeLog file was updated every 15 minutes. Now the ChangeLog file doesn't exist in the repository at all. Instead it's generated with "hg log --style=changelog" when running "make dist".

v1.0.0 released
by Timo Sirainen 13 Apr '07

13 Apr '07

http://dovecot.org/releases/dovecot-1.0.0.tar.gz http://dovecot.org/releases/dovecot-1.0.0.tar.gz.sig It took almost 5 years, but it's finally ready. I'm not expecting to release v1.0.1 anytime soon, unless someone's been sitting on a major bug just waiting for v1.0 to be released. :) People wanting new features should start testing the upcoming v1.1. http://dovecot.org/nightly/ contains now snapshots from CVS HEAD. It already has tons of new features. I've been using it myself for half a year, so it should be mostly stable too. I'll write a separate mail about this later.

1.0.rc32 released
by Timo Sirainen 12 Apr '07

12 Apr '07

http://dovecot.org/releases/dovecot-1.0.rc32.tar.gz http://dovecot.org/releases/dovecot-1.0.rc32.tar.gz.sig Pretty late for changes if v1.0 is supposed to come out tomorrow, but I can't really leave these LDAP bugs unfixed. They shouldn't anyway break anything, so here's one more day for you people to find out about any bugs. One thing that I'm a bit concerned about is the addition of #define LDAP_DEPRECATED. I know it fixes crashes with OpenLDAP 2.3 + 64bit systems, but I hope it doesn't break compiling with some old versions or non-OpenLDAP libraries.. - LDAP, auth_bind=no: Don't crash if doing non-plaintext ldap passdb lookup for unknown user. This also broke deliver when userdb static was used. - LDAP, auth_bind=yes and userdb ldap: We didn't wait until bind was finished before sending the userdb request, which could have caused problems. - LDAP: Don't break when compiling with OpenLDAP v2.3 library - Convert plugin: Don't create "maildirfolder" file to Maildir root.

08 Apr '07

http://dovecot.org/releases/dovecot-1.0.rc31.tar.gz http://dovecot.org/releases/dovecot-1.0.rc31.tar.gz.sig mbox + NFS combination shouldn't break anymore. v1.0 still planned to be released next friday. - mbox: Give "mbox file was modified while we were syncing" error only if we detect some problems in the mbox file. The check can't be trusted with NFS. - Convert plugin: If directory for destination storage doesn't exist, create it. - Convert plugin: Mailbox names weren't converted in subscription list.

1.0.rc30 released
by Timo Sirainen 06 Apr '07

06 Apr '07

http://dovecot.org/releases/dovecot-1.0.rc30.tar.gz http://dovecot.org/releases/dovecot-1.0.rc30.tar.gz.sig So, this is it. Unless you can find a new and important bug within a week, this release is the same as v1.0. I'll only update the version number and NEWS file. Changes since rc29: * PAM: Lowercase the PAM service name when calling with "args = *". Linux PAM did this internally already, but at least BSD didn't. If your PAM file used to be in /etc/pam.d/IMAP or POP3 file you'll need to lowercase it now. + Send list of CA names to client when using ssl_verify_client_cert=yes. - IMAP: If message body started with line feed, it wasn't counted in BODY and BODYSTRUCTURE replies' line count field. - deliver didn't load plugins before chrooting

1.0.rc29 released
by Timo Sirainen 30 Mar '07

30 Mar '07

http://dovecot.org/releases/dovecot-1.0.rc29.tar.gz http://dovecot.org/releases/dovecot-1.0.rc29.tar.gz.sig Probably one more RC after this. * Security fix: If zlib plugin was loaded, it was possible to open gzipped mbox files outside the user's mail directory. + Added auth_gssapi_hostname setting. - IMAP: LIST "" "" didn't return anything if there didn't exist a namespace with empty prefix. This broke some clients. - If Dovecot is tried to be started when it's already running, don't delete existing auth sockets and break the running Dovecot - If deliver failed too early it still returned exit code 89 instead of EX_TEMPFAIL. - deliver: INBOX fallbacking with -n parameter wasn't working. - passdb passwd and shadow couldn't be used as master or deny databases - IDLE: inotify didn't notice changes in mbox file - If index file directory couldn't be created, disable indexes instead of failing to open the mailbox. - Several other minor fixes
