[Dovecot] v1.1.19 released
by Timo Sirainen 04 Oct '09

04 Oct '09

http://dovecot.org/releases/1.1/dovecot-1.1.19.tar.gz http://dovecot.org/releases/1.1/dovecot-1.1.19.tar.gz.sig This is hopefully the last v1.1.x release. - file_set_size() was broken with OSes that didn't support posix_fallocate() (almost everyone except Linux), causing all kinds of index file errors. - ldap: Fixed hang when >128 requests were sent at once. - Fixed a crash in saving messages where message contained a CR character that wasn't followed by LF (and the CR happened to be the last character in an internal buffer). - deliver: Don't send rejects to any messages that have Auto-Submitted header. This avoids emails loops. - Message decoding fixes (mainly for IMAP SEARCH, Sieve).

[Dovecot] v1.2.5 released
by Timo Sirainen 04 Oct '09

04 Oct '09

http://dovecot.org/releases/1.2/dovecot-1.2.5.tar.gz http://dovecot.org/releases/1.2/dovecot-1.2.5.tar.gz.sig I'll be more or less gone for next two weeks. Tomorrow I'm heading to MacSysAdmin in Sweden to give a Dovecot talk, the next week I'll be in Finland on vacation. After that I'm hoping to get v2.0.alpha1 released in October. * Authentication: DIGEST-MD5 and RPA mechanisms no longer require user's login realm to be listed in auth_realms. It only made configuration more difficult without really providing extra security. * zlib plugin: Don't allow clients to save compressed data directly. This prevents users from exploiting (most of the) potential security holes in zlib/bzlib. + Added pop3_save_uidl setting. + dict quota: When updating quota and user isn't already in dict, recalculate and save the quota. - file_set_size() was broken with OSes that didn't support posix_fallocate() (almost everyone except Linux), causing all kinds of index file errors. - v1.2.4 index file handling could have caused an assert-crash - IMAP: Fixes to QRESYNC extension. - virtual plugin: Crashfix - deliver: Don't send rejects to any messages that have Auto-Submitted header. This avoids emails loops. - Maildir: Performance fixes, especially with maildir_very_dirty_syncs. - Maildir++ quota: Limits weren't read early enough from maildirsize file (when quota limits not enforced by Dovecot) - Message decoding fixes (mainly for IMAP SEARCH, Sieve).

[Dovecot] Configuring for virtual users in Postfix
by Jerry 03 Oct '09

03 Oct '09

FreeBSD-7.2 with Postfix-2.7x OK, this is my first attempt to configure Dovecot using Postfix and virtual users. In the LDA.Postfix.txt file, there is a reference to making the following setting: dovecot_destination_recipient_limit = 1 virtual_mailbox_domains = your.domain.here virtual_transport = dovecot However, Postfix does not recognize the dovecot_destination_recipient_limit = 1 setting. There is a "virtual_destination_recipient_limit =" setting in Postfix. Is that the setting that I should tweak? -- Jerry gesbbb(a)yahoo.com There is no TRUTH. There is no REALITY. There is no CONSISTENCY. There are no ABSOLUTE STATEMENTS. I'm very probably wrong.

[Dovecot] Mailbox locking problem with iphone and POP3
by Bill Dunn - VCI Internet Services 03 Oct '09

03 Oct '09

I have a problem I can't seem to fix. I have dovecot configured to do POP3 with plain text authentication using a MySQL database. I am using Dovecot 1.0.7 with fcntl locking. My problem has been when an iPhone/iPod checks email. The iPhone/iPod doesn't disconnect with a TCP FIN packet and it leaves the mailbox in a locked state and prevents the user's desktop from checking email. I have tried changing the file locking method and other config file options without any luck. Oddly, I am using the last version of cucipop on another server with fcntl and lockf file locking and it doesn't have this problem. If someone could clue me in I'd be very grateful. Bill

[Dovecot] IMAP proxying for ALL users to internal mail server
by Vitaliy Vladimirovich 02 Oct '09

02 Oct '09

Hi! How must I adjust Dovecot for proxying all users from the Internet to the internal Exchange Mail Server? This is my config files (most important): dovecot.conf protocol imap { #listen = *:10143 ssl_listen = 194.0.148.10:993 auth default { mechanisms = plain login passdb passwd-file { args = /usr/local/etc/dovecot-%Ls.conf } } dovecot-imap.conf testmail1@example.org::0:0::::proxy host=10.0.10.3 port=143 nopassword With this configurations all works fine, but if I trying change dovecot-imap.conf as below %n@%d::0:0::::proxy host=10.0.10.3 port=143 nopassword I get an error: Oct 2 15:10:58 relay dovecot: auth(default): client in: AUTH 1 PLAIN service=imap secured lip=199.10.149.10 rip=199.10.149.3 lport=993 rport=28316 resp=<hidden> Oct 2 15:10:58 relay dovecot: auth(default): passwd-file(testmail1(a)example.org,199.10.149.3): lookup: user=testmail1(a)example.org file=/usr/local/etc/dovecot-imap.conf Oct 2 15:10:58 relay dovecot: auth(default): passwd-file(testmail1(a)example.org,199.10.149.3): unknown user Oct 2 15:10:59 relay dovecot: auth(default): new auth connection: pid=62532 Oct 2 15:11:00 relay dovecot: auth(default): client out: FAIL 1 user=testmail1(a)example.org Any ideas??

[Dovecot] Folder Management Dovecot >1.2
by Carlos Candeias 02 Oct '09

02 Oct '09

Regardless of the mail client no user can modify, move, delete or subscribe an imap folder with Dovecot >1.2.1 (meanwhile 1.2.5). Dovecot apparently have some dotlock problems: (From dovecot.log) Oct 02 14:58:19 IMAP(jcci): Error: fchown(/candeias/home/jcci/.mail/Maildir/subscriptions.lock, -1, 0(root)) failed: Operation not permitted (egid=1003(management), group based on /candeias/home/jcci/.mail/Maildir) Oct 02 14:58:19 IMAP(jcci): Error: file_dotlock_open() failed with subscription file /candeias/home/jcci/.mail/Maildir/subscriptions: Operation not permitted Oct 02 14:58:20 IMAP(jcci): Error: fchown(/candeias/home/jcci/.mail/Maildir/subscriptions.lock, -1, 0(root)) failed: Operation not permitted (egid=1003(management), group based on /candeias/home/jcci/.mail/Maildir) Oct 02 14:58:20 IMAP(jcci): Error: file_dotlock_open() failed with subscription file /candeias/home/jcci/.mail/Maildir/subscriptions: Operation not permitted Oct 02 14:58:20 IMAP(jcci): Error: fchown(/candeias/home/jcci/.mail/Maildir/subscriptions.lock, -1, 0(root)) failed: Operation not permitted (egid=1003(management), group based on /candeias/home/jcci/.mail/Maildir) Oct 02 14:58:20 IMAP(jcci): Error: file_dotlock_open() failed with subscription file /candeias/home/jcci/.mail/Maildir/subscriptions: Operation not permitted Oct 02 14:58:21 IMAP(jcci): Error: fchown(/candeias/home/jcci/.mail/Maildir/subscriptions.lock, -1, 0(root)) failed: Operation not permitted (egid=1003(management), group based on /candeias/home/jcci/.mail/Maildir) Oct 02 14:58:21 IMAP(jcci): Error: file_dotlock_open() failed with subscription file /candeias/home/jcci/.mail/Maildir/subscriptions: Operation not permitted Oct 02 14:58:21 IMAP(jcci): Error: fchown(/candeias/home/jcci/.mail/Maildir/subscriptions.lock, -1, 0(root)) failed: Operation not permitted (egid=1003(management), group based on /candeias/home/jcci/.mail/Maildir) Oct 02 14:58:21 IMAP(jcci): Error: file_dotlock_open() failed with subscription file /candeias/home/jcci/.mail/Maildir/subscriptions: Operation not permitted This was an attemt of changing a subscription. Another weird point: I can create an IMAP folder although it does not show up in the folder list. But the new folder is in the subscription list, just marked as unsubscribed and there is no way to change that. This problem is safely reproducible and I wonder whether I should be really the only person having this trouble. I'm using MAILDIR and simple plain test authentification (internal mail server). The location is mail_location: maildir:~/.mail/Maildir which means a subfolder in each user's home directory. All homes are exported to NFS, but the Dovecot is just on the same server and thus accesses locally. Downgrade to version 1.1.17 solves all problems. Archlinux x86_64, Linux 2.6.30 It would be really great if somebody could understand the cause and suggest a solution!

[Dovecot] Problem with LSUB and public namespace
by Julien Danjou 02 Oct '09

02 Oct '09

Hi, I'd like to know if the following is normal. I've a setup with 2 namespace (private/public) where each user can use subscriptions. This problem is triggered by claws-mail, which uses LSUB to get subscribed mailboxes: * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE AUTH=PLAIN] Dovecot ready. . login user password . namespace * NAMESPACE (("INBOX." ".")) NIL (("public." ".")) . OK Namespace completed. . subscribe public.Admin . OK Subscribe completed. . LSUB "" "%" * LSUB () "." "INBOX" . OK Lsub completed. LSUB does not return "public" as namespace :-( Is this a bug in dovecot, a bug in Claws mail, or a misconfiguration of my dovecot server? I can provide more info if needed. Cheers, -- Julien Danjou // ᐰ <julien(a)danjou.info> http://julien.danjou.info // 9A0D 5FD9 EB42 22F6 8974 C95C A462 B51E C2FE E5CD // There is nothing under this line.

[Dovecot] Disconnected: Too many invalid IMAP commands
by Gabriele 02 Oct '09

02 Oct '09

Greetings, I'm having big issues here, hope you can help me… Ubuntu Server 8.04, postfix 2.5.1, dovecot 1.0.10, postfixadmin (MySQL+ virtual users)… I am trying to move e-mails from an old IMAP account to my new dovecot IMAP server accounts. The old server is EIMS (Eudora Internet Mail Server, so a sort of mbox format)… I move messages by drag 'n' dropping in Mozilla Thunderbird. No problems with messages under 4MB size (there are huge messages, up to 25MB), but as soon as I try to move messages from 4MB and up, the connection hangs, nothing happens, the application becomes barely responsive, I have quit and re-open it to make it behave properly. In the logs, I read (user and IPs are fake, here): Sep 18 07:52:06 in dovecot: imap-login: Login: user=<user@my-domain>, method=PLAIN, rip=123.123.123.123, lip=123.123.123.123 Sep 18 07:52:06 in dovecot: IMAP(user@my-domain): Disconnected: Too many invalid IMAP commands. Could it be a client (Thunderbird) issue? I have tried with Apple Mail 4.1, same problem, same logs. Could it be a quota limit (googling around, I read that sometimes the error may be triggered by dovecot when exceeding the quota limit) Accout usage is actually at 1%… Could drag 'n' drop be the wrong way to have things done? I have also downloaded the huge e-mails from EIMS to Thunderbird Local Folders, the problem arises when I try to upload, so the culprit seems to be the new "system". I really need help at this point… any hints? Thanks in advance for any help you will offer. Gabriele

[Dovecot] Password and special caracter
by Gilles Albusac 02 Oct '09

02 Oct '09

Problem : I have a problem with special character in the password. Character like ! * é are deleted My configuration : - a smtp server with Postfix 2.6 and Dovcot 1.1.11. - a windows 2003 server with active directory for accounts and boxes I use SMTP / SASL on my postfix 2.6 to authenticate my remote laptop users (allow legitimate users to relay mail). To do that, I use SASL Dovecot fonctionnality and ldap request to verify login/password who are declared on a server in Windows 2003 (Active Directory). It works fine with simple password but not with complex password. I have a problem with special character in the password. Character like ! * é are deleted before comparaison. Any idea ? Regards

[Dovecot] I can acces my pop3 account but I can't send an email trough smtp

Dear my friends.... I use OpenSuSE 11.1, KMail and DoveCot version: " sussy:/etc/ssl/certs # dovecot --version 1.1.7 ". This is the configuration of my DoveCot: " sussy:/etc/ssl/certs # dovecot -n # 1.1.7: /etc/dovecot/dovecot.conf # OS: Linux 2.6.27.29-0.1-default i686 openSUSE 11.1 (i586) base_dir: /var/run/dovecot/ log_path: /var/log/dovecot.log protocols: imap imaps pop3 listen(default): * listen(imap): * listen(pop3): *:110 ssl_disable: yes disable_plaintext_auth: no login_dir: /var/run/dovecot//login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login login_greeting: Dovecot of MyGoogle.Com ready. mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 auth default: debug_passwords: yes passdb: driver: pam userdb: driver: passwd ". I have created local linux user account on my Postfix+DoveCot server. I also can access the content of my mailbox from my KMail. I am so happy but once I try to send email (testing the smtp) than I realize that I can't send an email from my email client (KMail). I use this setting on my email client: 1. 'incoming mailserver' == 'outgoing mailserver' == 'mail.mygoogle.com' (pseudonome). Also username and password are all the same between incoming/outgoing mailserver, namely the local userlogin of LINUX. As the username, I put 'ricky' (but not 'ricky(a)mygoogle.com'). 2. smtp authentication: No encryption and plaintext. The error message on my KMail is: " Sending failed: Your SMTP server does not support The server responded: "5.7.8 Error: authentication failed: generic failure". Choose a different authentication method. The server responded: "5.7.8 Error: authentication failed: generic failure" The message will stay in the 'outbox' folder until you either fix the problem (e.g. a broken address) or remove the message from the 'outbox' folder. The following transport was used: mygoogle.com Do you want me to continue sending the remaining messages? " and also: " Sending failed: Your SMTP server does not support The server responded: "5.7.8 Error: authentication failed: generic failure". Choose a different authentication method.

The following transport was used: mygoogle.com ". I'm stucked again. Please help me. Tell me where my mistake. Thank you very much in advance.

[Dovecot] Encryption Plugin
by Patrick McLean 01 Oct '09

01 Oct '09

Hi, There was a discussion a few months ago about a plugin for encrypting email before it hit the disk on the server, and doing transparent decryption while serving data to the client, see: http://www.dovecot.org/list/dovecot/2009-July/041262.html We have a client/user who is interested in such a plugin, and I was wondering if there has been any progress on it yet. In our particular case, server-side on-the-fly decryption would be acceptable. This service is useful in the case of a somewhat paranoid user who does not want the IT staff to have direct access to their email, without going through some major hoops (http://hushmail.com actually offers both server and client side decryption for these reasons). The way I would imagine the plugin working is public-key encryption being done on the message as it was being delivered (plug in to dovecot's deliver). Then when a client connects, the private key is decrypted with the user's password and used to decrypt the messages on the fly. Depending on performance, it may be an idea to convert messages to use symmetric with rotating keys encrypted with the public key encryption. If this were going to be done, I would think an IMAP protocol extension may be an idea so client-side encryption would be an option as well, so there would be end-to-end security.

[Dovecot] OT: IMAP folder aliases
by Patrick Ben Koetter 01 Oct '09

01 Oct '09

It seems that there is no standard for folder names that deal with typical message classes such as drafts, outbox, sent, spam etc. At least there's no common sense on a naming convention that tells how client should handle this. Worse than this, most IMAP clients auto-create folders according to their own naming convention if they don't exist. Every client introduces its own view. Users OTOH expect a single view that makes it easy for them to find their messages. They are unwilling to search in "sent", "sent-mail" or "Sent items" for "messages that have been sent". I doubt that software producers will adopt a standard naming convention if it was introduced within a useful time span. Has anyone seen an approach or a solution that solves the problem from a users point of view? A server side alias list that maps to a server standard? p@rick -- state of mind Digitale Kommunikation http://www.state-of-mind.de Franziskanerstraße 15 Telefon +49 89 3090 4664 81669 München Telefax +49 89 3090 4666 Amtsgericht München Partnerschaftsregister PR 563

Fair enough. But I never saved the tail when the problem occured. I can now extract this again from the info log (getting everything between 11:06 to 11:08 which should be within the problem time...). Who should I send it to? It's 181 lines to 'privatize' and I'd prefere not to send a unprivatized file to the list...

This may be enough for Timo, but its always better to give the full logs of one of these transactions - not just the dovecot error log, but full system logs, showing the message entering the system, each step of processing, and ending with the final delivery (attempt)... -- Best regards, Charles Marcus I.T.

[Dovecot] Compile dovecot 1.2.5 with managesieve patch 0.11.9?
by Seba 01 Oct '09

01 Oct '09

Hi, is it possible to compile dovecot 1.2.5 with the managesieve patch 0.11.9 which is for dovecot 1.2.4 or is it better to wait if a new managesieve patch is released? Maybe 1.2.5 will work too? Thanks, Seba

[Dovecot] Some issues in Dovecot 1.2.5 after upgrade from 1.0.15
by Chris Wakelin 01 Oct '09

01 Oct '09

We upgraded from Dovecot 1.0.15 to 1.2.5 last night, on Solaris 10 using mboxes, mostly without issues. However I had to trash the index/cache files (too many folders were showing corruption issues which is especially bad for Prayer Webmail ".prayer" folders that store preferences; Prayer sees a disconnection as the folder being missing!). I've had one imap process panic in mailbox sync (as I mentioned above, the index files have been newly created in 1.2.5): > Sep 30 09:57:10 imap-login: Info: Login: user=<xxxxxxxx>, method=PLAIN, rip=134.225.xx.xx, lip=134.225.16.6 > Sep 30 09:57:10 imap-login: Info: Login: user=<xxxxxxxx>, method=PLAIN, rip=134.225.xx.xx, lip=134.225.16.6 > Sep 30 09:57:11 IMAP 25384 xxxxxxxx 134.225.xx.xx : Panic: file mail-index-sync-update.c: line 933 (mail_index_sync_map): assertion failed: (map->hdr.indexid == index->indexid || map->hdr.indexid == 0) > Sep 30 09:57:11 dovecot: Error: child 25384 (imap) killed with signal 6 (core dumped) This looks like it was the user's first connection since the upgrade, as well.

[Dovecot] Virtual Plugin
by Darvin Denmian 01 Oct '09

01 Oct '09

I activated Dovecot's Virtual Plugin in my configuration and created dovecot-virtual file with the following content: [quote] # ~/Maildir/virtual/Flagged/dovecot-virtual * flagged [quote] When I flag some messages these messages automatically appears inside my Virtual Folder called "Flagged", but once inside this folder , when I "Unflag" the message, It doesn't disapear from my virtual folder. Is this expected? I'm using dovecot12-1.2.5-2.1 on a Opensuse 11.1 I hope you understand my brazilian english :) Thanks
