Tue Feb 20 14:10:15 EET 2007

Released the 23th 1.0 release candidate. Documentation is probably the only important thing left before v1.0.

Tue Feb 6 18:16:45 EET 2007

Mon Oct 9 21:34:01 EEST 2006

Released the eighth 1.0 release candidate.

Sat Oct 7 20:46:06 EEST 2006

The server move is now complete. Everything should be working again as usual. Please send a mail if something is still broken. The server and the network connection was provided by Nebula, thanks.

Fri Oct 6 17:02:23 EEST 2006

dovecot.org will be moved to a new server in a new location sometimes tomorrow day/night (EEST, saturday). It'll be down temporarily so that I can get everything fully synchronized between the old and the new machines.

Thu Oct 5 21:27:59 EEST 2006

Looks like dovecot.org's hard disk is dying. A reboot fixed it this time, but hopefully I can get it moved to a new and better server soon. I actually had backups of most of the stuff though, so if it really had died completely it wouldn't have been a disaster :)

Fri Aug 18 01:23:19 EEST 2006

Released the seventh 1.0 release candidate.

Mon Aug 7 02:41:53 EEST 2006

Released the sixth 1.0 release candidate. This should finally take care of the SSL hangs that have caused so much trouble lately. So we should be near v1.0 again, I think..

Thu Aug 3 00:24:01 EEST 2006

Released the fifth 1.0 release candidate. I shouldn't have started releasing anything today.. This is what RC3 really should have been.

Wed Aug 2 22:49:31 EEST 2006

Tue Jun 13 19:17:27 EEST 2006

Released 1.0 beta9 version. Fixes a lot of different bugs, so it's a recommended update for everyone.

Fri May 12 12:30:17 EEST 2006

Released 1.0 beta8 version. Most importantly fixes a security hole with mboxes. Also several other fixes.

Wed Apr 12 14:54:25 EEST 2006

Released 1.0 beta7 version. Beta6 didn't really fix the authentication problem, this one does..

Wed Apr 12 11:07:58 EEST 2006

Released 1.0 beta6 version. Fixes several bugs, especially one related to authentication which got broken in beta4.

Tue Apr 4 11:39:39 EEST 2006

Mon Jan 16 22:52:51 EET 2006

Released 1.0 beta1 version. Starting from this version I'm offering 1000€ for the first person to find a remotely exploitable security hole from Dovecot.

Sun Dec 11 00:37:25 EET 2005

Released 1.0 alpha5 version. Most importantly fixes a couple of crashes and several mbox bugs. Also contains beginnings of a new mailbox format named dbox.

Thu Oct 20 13:02:52 EEST 2005

Released 1.0 alpha4 version. Fixes a couple of important (although somewhat rare) problems with IMAP and POP3, so this is a highly recommended upgrade for 1.0alpha and 1.0test users.

Fri Sep 23 16:50:29 EEST 2005

Released 1.0 alpha3 version. This is the recommended Dovecot version to be used. It may of course still have some problems, that's why it's called an alpha.

Sun Sep 11 23:32:43 EEST 2005

Released 1.0 alpha2 version. This is the recommended Dovecot version to be used. It may of course still have some problems, that's why it's called an alpha.

Thu Aug 18 20:15:37 EEST 2005

Released 1.0 alpha1 version. This is now the recommended Dovecot version to be used. It may of course still have some problems, that's why it's called an alpha.

Fri Feb 11 20:33:30 EET 2005

Released 0.99.14 version. Most importantly some fixes for mbox code so it won't allow external mails to grow mail UID counter by sending X-UID headers. Several other fixes all around.

If you don't need support for keywords, it might be a better idea nowadays to use dovecot-stable branch instead of 0.99.x releases. More information about it in here.

Thu Jan 6 20:32:25 EET 2005

Released 0.99.13 version. Fixes SQL/LDAP authentication, adds CRAM-MD5 authentication mechanism, etc.

For non-production use you may try 1.0-test releases. They are finally stabilizing and have entirely rewritten index file and mbox code.

Tue Dec 7 01:02:32 EET 2004

Released version. The only difference to 0.99.12 is that it now doesn't require GNU make to build.

Sun Dec 5 05:25:12 EET 2004

Released 0.99.12 version. Fixes various bugs.

Sat Sep 4 14:17:54 EEST 2004

Released 0.99.11 version. Fixes various bugs.

Sat Jul 31 03:08:23 EEST 2004

Released version. Just MySQL compilation fix and PostgreSQL reconnection fix.

Fri Jul 30 05:47:43 EEST 2004

Released version. Most importantly fixes BODY and BODYSTRUCTURE replies if mail had MIME parts that didn't have Content-Type header set. Also fixes MySQL and PostgreSQL support to reconnect to server if connection is lost.

Wed Jul 14 13:14:45 EEST 2004

Released version. Fixes Dovecot disconnecting client if it wasn't fast enough to download mail in 30 seconds. Also implements outlook-pop3-no-nuls workaround to fix Outlook/OE hanging if mails contain NUL characters.

1.0-test releases still break from time to time while I change things, but there doesn't seem to be any longstanding bugs left. First alpha releases aren't too far away.

Sun Jun 20 01:31:15 EEST 2004

Released version. Most importantly fixes crashes with maildir. Includes also a few new features.

1.0-test releases are beginning to look good too. I'm finally using them myself with mbox. The new mbox code is fast.

Thu May 27 18:31:40 EEST 2004

Released version. Most importantly fixes mbox corruption in certain situations, hopefully it was the only one. Fixes other non-mbox problems as well, so this is a recommended upgrade. Only new feature is MySQL authentication.

1.0-test releases haven't stabilized as fast as I've hoped, it may still take a while to get v1.0 released..

Mon Apr 26 15:58:00 EEST 2004

Dovecot is far from dead. I've just been slowly and quietly working with index file code rewrite, which has taken a long time. The end result however is that it will be faster, easy to use with NFS/clusters, works extremely well with shared mailboxes with lots of users, etc.

I've released the first test version of it. Just remember that it's only a very early test version which might break badly and delete all your mail (NOTE: and I'm only talking about 1.0-test releases here, not 0.99.x which you can get from download page). Also see the release announcement.

We also have a logo now, thanks to Olli Rajala from Anima Vitae.

Mon Nov 24 21:26:30 EET 2003

Released A few more bugfixes. UPDATE: and

Mon Nov 10 20:54:43 EET 2003

Released It's basically 0.99.10 release with several bugfixes backported from CVS. UPDATE: released to fix one more bug.

Sat Sep 13 04:56:08 EEST 2003

Added Dovecot Wiki. Feel free to update it :)

Thu Jun 26 19:22:06 EEST 2003

0.99.10 released. Faster and better maildir synchronization. Support for read-only mailboxes. ANONYMOUS SASL support. OpenSSL fixes. Lots of smaller fixes. Default PAM service name also changed from "imap" to "dovecot". See beginning of NEWS file. UPDATE: Searching address fields can crash sometimes, this patch fixes. Auth process crashes if user doesn't have home directory set, this patch fixes. Some BODY and BODYSTRUCTURE replies missed data for message/rfc822 MIME parts causing clients to break, this patch fixes. Some partial BODY[part] fetches may have returned data incorrectly, this patch fixes.

Sat May 3 21:48:37 EEST 2003 released. A few bugfixes. UPDATE: Some FreeBSD systems fail at startup if SSL is disabled, this patch fixes. Another patch may fix some mail fetching corruption with CR+LF linefeeds.

Mon Apr 28 19:37:59 EEST 2003

0.99.9 released. Faster mbox updating, PostgreSQL authentication support, permanently stored UIDs outside index files and lots of bugfixes. Because of the large mbox code changes, you might want to backup your mboxes just in case. UPDATE: It doesn't compile with OpenBSD, this patch fixes.

Tue Apr 15 16:49:45 EEST 2003

You can get 0.99.9-test releases from here. Note that they're still somewhat buggy, especially maildir seems to have problems. It includes code to support permanently saved message UIDs for both mbox and maildir in NFS-safe storage. Previously they were stored only in index files. mbox rewriting is also more optimized, it shouldn't anymore rewrite the whole file if message flags were updated from beginning of file.

Tue Mar 11 23:12:34 EET 2003

Since I couldn't get 0.99.9 out as soon as I thought, I decided to now put out bugfix-patched 0.99.8 and call it It fixes several crashes and buggy behaviour. UPDATE: Renaming subfolders is still buggy with maildir, this patch fixes. Partial body fetches are buggy, this patch fixes. Using LITERAL+ with APPEND (done by eg. Mozilla) was somewhat broken, this patch fixes. Subfolders had some problems with Maildir, this patch fixes.

Tue Feb 25 23:18:56 EET 2003

0.99.8 released. If you're upgrading, there's a few changes that you must be aware of - read the beginning of NEWS file. New features include a small POP3 server, LDAP authentication, support for LITERAL+, MULTIAPPEND, UNSELECT, IDLE, CHILDREN and LISTEXT IMAP extensions. Also fixes the message flag update problems when copying messages with mbox. UPDATE: There's some quoting problems with ENVELOPE and BODYSTRUCTURE replies, this patch fixes (they may already be cached in indexes, so delete .imap.index* files if it doesn't help).

Tue Feb 4 05:28:44 EET 2003

0.99.8-test1 released. It seems to be working, but I'd still be careful with it. This release contains POP3 server. It has also half-working LDAP support which will be finished for the next real release. I'm also hoping to get some SQL support for it. UPDATE: test4 out, LDAP should fully work now. UPDATE: test10 out, this should be same as final, assuming I don't find any problems.

Tue Jan 14 15:28:30 EET 2003

Released 0.99.7. Broken hash table code in .6 caused various problems (but of course none happened to me with the 2 days testing period..). UPDATE: vpopmail support doesn't compile, this patch fixes. PLAIN authentication is broken, mostly a problem with Pine, this patch fixes.

Tue Jan 14 00:03:57 EET 2003

Released 0.99.6. Supports THREAD extension! Now we should finally be able to fully work with IMAP webmails. Contains also quite a lot of bugfixes, as usual..

Sat Jan 11 22:21:33 EET 2003

0.99.6rc3 out, supports THREAD extension! SORT extension works much faster too now. Go try if it works with your favourite IMAP webmail.

Tue Jan 7 01:30:38 EET 2003

0.99.6rc2 out, rc1 didn't even compile.

Mon Jan 6 22:35:03 EET 2003

Released 0.99.6 release candidate 1. Fixes a few nasty bugs.

Thu Jan 2 16:01:18 EET 2003

Released 0.99.5. Includes many bugfixes and support for SORT extension.

Fri Dec 27 18:06:04 EET 2002

Released 0.99.5rc2. Just a few more fixes. If this works with gcc/powerpc, it should be pretty much the final release.

Sun Dec 22 20:26:58 EET 2002

Released 0.99.5 release candidate. Don't yet put into production, but testing would be fine. See release notes.

Sun Dec 1 18:39:42 EET 2002

0.99.4 released, fixes a few nasty bugs. I'd say this is the first release that could be considered almost "stable". There's no more "weird bugs" that I know of.

Wed Nov 27 00:04:20 EET 2002

0.99.3 released, fixes the mbox EXPUNGE corruption. Strange, I had been using Dovecot for days without noticing this. Guess I'll always delete only the most recent mails which didn't trigger the bug..

Tue Nov 26 23:00:00 EET 2002

0.99.2 released. Still more compiling fixes, one locking related bugfix (which I forgot to mention in changelog), and quite a lot of code cleanups. UPDATE: There's still something wrong with mbox and expunging messages - 0.99.3 probably out soon again..

Mon Nov 25 12:53:41 EET 2002

0.99.1 released. Fixes a few compiling issues, includes a few missing docs and a script to easily generate a self-signed SSL certificate.

UPDATE: vpopmail authentication still wasn't working right because it's library is buggy. Here's a kludgy patch to fix it, also includes a fix to make sure anything written to stdout (where vpopmail might write too) goes to /dev/null.

Sun Nov 24 19:39:31 EET 2002

0.99.0 released. All the major features planned for 1.0 are done now. This release replaces hash index file with binary tree file making dovecot perform better in certain conditions, especially with huge mailboxes. Other new features include support for SEARCH CHARSET, OpenSSL as alternative to GNUTLS, safe mbox locking and lots of smaller things, see the NEWS file.

Tue Oct 8 03:42:50 EEST 2002

I did some benchmarks today with a huge mailbox, mostly to test Dovecot's new binary tree indexing, which does make it perform excellently in all situations. I compared it against UW-imapd, Cyrus and Courier. Dovecot performs quite well against them, but for some reason loses in raw I/O speed. Also Dovecot+mbox still needs more optimizations to be as fast as UW-imapd. Note that this benchmark doesn't reflect any real world situation, but I think it shows quite well how IMAP servers scale. UPDATE: the I/O speed differences were caused by filesystem. When I began using the same mail files as Cyrus, BODY.PEEK[] got down to 1:41, easily beating Cyrus' 2:25.

Sun Oct 6 00:29:12 EEST 2002

0.98.4 released. Two bugfixes: BODY and BODYSTRUCTURE returned invalid data with message/rfc822 content and messages larger than 256k missed sending CR in some situations causing breakage. Also some fixes to make it compile with HP/UX ANSI C compiler. Next release will contain new binary tree code which should make Dovecot much faster in some situations, especially with large mailboxes.

Tue Oct 1 00:25:47 EEST 2002

0.98.3 released. Just noticed a nasty bug with BODY and BODYSTRUCTURE replies which had been crashing my Evolution (thought it was just because I was running the 1.2 beta).. (UPDATE: well, actually there's still one bug with embedded message/rfc822 mails, if anyone wants that fixed I'll release .4)

Mon Sep 30 23:37:48 EEST 2002

0.98.2 released. Most importantly mbox fixes, desync fixes with multiple clients and SEARCH ignored all but first argument.

Tue Sep 24 19:52:54 EEST 2002

0.98.1 released. Guess I should have waited one more day before releasing 0.98 :) This fixes a few mbox problems and should finally make it safe to use. Also fixes a bug of not allowing to save mail larger than 8kB.

Mon Sep 23 20:25:21 EEST 2002

0.98 released. This release includes LOTS of bugfixes after almost 4 weeks of actual use. We've mostly tested with Outlook 2000, Outlook Express 6 and Evolution 1.0.8. I haven't heard of a single bug in maildir for several days, and mbox worked quite well first time today :)

New features include vpopmail authentication, ability to run properly when there's no disk space left to allow user to delete mail, and full support for mbox.

Thu Sep 5 19:43:21 EEST 2002

Just a small status update: Until recently I had been using Dovecot mostly as read-only. Now that we actually began using it for sending mails, a bit too many bugs were found :) I think most of them (or worst of them) are now fixed in CVS. Next release should come after I've fixed all the known problems so far and seen no bugs for a few days.

Thu Aug 29 03:03:08 EEST 2002

v0.97 released. This is a major cleanup release. My near future goal is to make it impossible to crash Dovecot no matter what you did (not counting the bugs ;). This release also adds support for files larger than 2GB with Linux and Solaris. Also mbox support seems to work quite well now, except messages can't be deleted and message flags aren't stored into the mbox file itself (ie. dovecot sees the changes, but other MUAs don't).

Thu Aug 8 18:47:46 EEST 2002

v0.96 released. This release actually seems to work :) Added support for STARTTLS and custom message flags.

Wed Jul 31 22:46:23 EEST 2002

v0.95 released. Added support for SSL and DIGEST-MD5.

Mon Jul 29 04:48:13 EEST 2002

v0.94 released. Several bugs were found and fixed after I tried to run it with Solaris 8. Supports now also running as non-root, if you just can get imap-auth to authenticate yourself without them.

Mon Jul 29 00:30:26 EEST 2002

Fourth release, with "alpha" status this time.

Sat Jul 27 23:55:14 EEST 2002

And a third release, messages can be deleted with maildir and Date-field parser is implemented.

Sat Jul 27 18:14:36 EEST 2002

Second developers release, user authentication actually works now. At least with shadow files, not sure about PAM.

Wed Jul 24 11:13:20 EEST 2002

I think I figured out an ideal solution for the authentication problems. See design.txt, all comments welcome. Updated other parts of it as well.
