[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

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

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 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 ". 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.

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

[Dovecot] deliver doesn't support !include directive, mail is bounced
by Christoph Berkemeier 30 Sep '09

30 Sep '09

Hello, dovecot deliver is used here as a LDA. When I add !include /usr/local/etc/$INCLUDE.FILE to my dovecot.conf I get this error in the maillog: relay=local, delay=0.04, delays=0.02/0/0/0.02, dsn=5.3.5, status=bounced (local configuration error. Command output: Fatal: Error in config file /usr/local/etc/dovecot.conf: deliver doesn't support !include directive /usr/local/etc/$INCLUDE.FILE contains: listen: $HOSTNAME ssl_cert_file: /etc/$FILE ssl_key_file: /etc/$FILE auth_krb5_keytab = /etc/$FILE It would be nice if this bug gets fixed or a comment add, that you can not use include, when you use deliver as your LDA.

[Dovecot] deliver: Fatal: setgid(114) failed with euid=8, gid=8, egid=8: Operation not permitted
by Fredriksson Turbo 30 Sep '09

30 Sep '09

I'm calling 'deliver' from Postfix and in some cases from Procmail. I set this system up more than six months ago and it's been working flawlessly until yesterday (16:52:19 local time) when it, without any apparent reason, just stopped delivering mails! Lots of checking and googling (I've forgot how exacly I setup the system :), I made 'deliver' SUID and it worked again... But it seems that all mails that was received between 16:52:19 and 11:07:52 (which was the last mail that couldn't be delivered) is lost! Is there any way to avoid mails being lost for reasons such as this? Is this a Postfix, Procmail or Dovecot thing? This system runs on a Ubuntu Intrepid: Postfix v2.5.5-1 Procmail v3.22-16ubuntu3 Dovecot v1:1.1.4-0ubuntu1.3 Thinking it over again (when double checking this mail), it might have been a automatic "de-SUID thingie or other" in Ubuntu. If memory serves me right, there used to be something like that in Debian long ago... But for whatever reason it DID happen, I'd appreciate an idea on how to avoid loosing mails if something happens to the delivery process...

[Dovecot] sieve & vacation - ignores "days" parameter
by Jacek Osiecki 30 Sep '09

30 Sep '09

Hi, I am going further with dovecot configuration. Finally managed to configure roundcube 0.3 with managesieve plugin. And it works, although... not perfectly :( For some issues probably roundcube-managesieve is guilty, but simply the sieve plugins seems to work wrong. Here is my sieve file: require ["vacation","fileinto"]; # rule:[wakacje] if anyof (true) { vacation :days 7 text: I am on vacation . ; } # rule:[silver-save] elsif allof (header :is "From" "joshua(a)hybrid.pl") { fileinto "myown"; stop; } And it seems, that sieve ignores ":days 7" parameter. Every time I send the email to this account, I receive the automatic answer. Maybe I misconfigured something? Where does vacation plugin store the information on emails that have already received the automatic answer? Best regards, -- Jacek Osiecki joshua(a)ceti.pl GG:3828944 I don't want something I need. I want something I want.

I'm trying to clean up the code for Dovecot v2.0 and I just keep coming back to the same thought: Is having the super-fast maildir -> single-dbox migration really actually a good idea? Some problems with it: 1. Makes the code more complex.. And I've already fixed many bugs related to that, maybe not all. 2. Having some mails in maildir format and others in dbox format isn't really good in long term. The super-fast migration was mainly meant to be used as a quick and easy way to start using dbox and then slowly convert maildir files to dbox files. 3. There's currently no way to actually convert the migrated maildir files to dbox format. And I'm not really sure how such a tool would even be used. "doveadm -u <username> dbox convert-old-maildir-files" run one user at a time?.. Maybe a better alternative would be to simply do a proper full migration to dbox format, a few users at a time so disk I/O wouldn't explode? dsync especially could be helpful here. convert plugin could be replaced with a dsync plugin and then a migration could be done with: 1. Run a "pre-migration" dsync for n users (not absolutely required, but a good idea to avoid login delays). 2. Enable dsync plugin for the users (or this could be enabled always). 3. Switch users to dbox format. 4. Run a "post-migration" dsync for the users. If any user logged in before the post-migration was finished, the dsync plugin would finish the migration for that user. 5. Goto 1 with another set of users, repeat until finished with all users.

[Dovecot] Problem with dict-quota, deliver killed by delivery attempt

Hi, I can't get quota lda plugin working... When I enable quota plugin, the emails (delivered by exim + dovecot-lda) are instantly rejected: 2009-09-29 16:36:12 1MsdoI-0000aJ-2L ** jacek(a)my-domain.pl R=mysql_localuser T=dovecot_delivery: Child process of dovecot_delivery transport (running command "/usr/lib64/dovecot/deliver -d $local_part@$domain -f $sender_address -a $original_local_part@$original_domain") was terminated by signal 9 (Killed) I have checked, that neither restart of dovecot nor delivery attempt tries to read the quotadict file (/etc/dovecot/dovecot-dict-quota.conf) - the atime is unchanged.

[Dovecot] getmail and Dovecot LDA deliver
by spacejam 29 Sep '09

29 Sep '09

Hello, my first post in this list. Hope it's the right place.:-) I'm having a problem running getmail together with Dovecot LDA for virtual users. To achive this I let getmail run under the user that owns the virtual email accounts-root. The problem is that getmail is running under the user vmail and therefore the emails received will be put into vmail's mailbox. But the emails getmail collected are actually for a virtual Dovecot user which has its maildir in a subdirectory of vmails home. The settings for the virtual users seem to be okay: I can login on Dovecot with virtual user account and I can send emails to Postfix for the virtual user. Postfix correctly uses devlier with the name of the virtual user and so the emails are going to the correct directory. For me it seems that getmail always uses the username under which getmail is currently running. As this must be a local user, getmails always announces this local user to deliver and deliver therefore puts the emails into the wrong account. My question is: How do I let deliver know that it should use a virtual user? I tried with the -d agrument in my getmail rc File, but deliver never accepts the parameter -d (always says unknown parameter -d). I tried as well to let getmail or deliver to be run as root, but then the emails will be delivered to roots home, which is not the goal too... Does anyone know a way how I can set getmail to handle emails for a virtual account properly? Any hint is appreciated as it already costed me hours of try-and-error Regards tobi -- View this message in context: http://www.nabble.com/getmail-and-Dovecot-LDA-deliver-tp24896318p24896318.h… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] Enabling security on POP3 and IMAP
by Richard Hobbs 29 Sep '09

29 Sep '09

Hello, Currently, on our new test server, I am offering IMAP on 143 and POP3 on 110. We would like to enable security on both of these protocols to attempt to eliminate the risk from an internal password-grabbing/content-grabbing attack. I presume this would mean enabling SSL, and a more securure authentication, right? Or are plain text passwords just sent over the SSL, and therefore perfectly secure? Also, what are the steps to enable security for these protocols on an already-configured server? Is it possible to offer encrypted and non-encrypted services simultaneously, so people have a choice of whether they want security or not? I know that's a bit weird, but for testing it would be useful. Finally, is there a way to monitor which users are connecting over the secure ports and which users are connecting over the non-secure ports? Thanks in advance!

[Dovecot] compressed IMAP traffic
by Leonardo Rodrigues 29 Sep '09

29 Sep '09

Simply (and maybe stupid) question ...... is there anything that can be easily used to automatically compress IMAP traffic between client and server ? I was thinking if the SSL/TLS code enables some kind of compression as well. the idea is to reduce IMAP traffic between server and clients and not using VPN-like solutions, the idea is just some IMAP4 standard client (compatible with SSL/TLS if that's the case) and nothing else. can something like that be done ? -- Atenciosamente / Sincerily, Leonardo Rodrigues Solutti Tecnologia http://www.solutti.com.br Minha armadilha de SPAM, NÃO mandem email gertrudes(a)solutti.com.br My SPAMTRAP, do not email it

[Dovecot] sieve vacation error
by Andre Rodier 28 Sep '09

28 Sep '09

Hello everybody, First, I want to thank the development team for the quality and the stability of dovecot. It's now running without problem since two years on my debian box. Next, I'd like you help me to solve the problem I have with vacation/sieve script. My configuration is debian lenny, with standard dovecot packages (1.0). I have setup the sieve plugin, using roundcube on another machine, and filter is working fine. fileinto is working, as well as forward and discard. However, vacation is not working at all, and I have no error message. The mails sent to the account marked as vacation are received, but the auto answer process is not working. Here the successful logs from the vacation reject script, that I temporary use: Sep 23 17:32:41 mail deliver(some.user): Loading modules from directory: /usr/lib/dovecot/modules/lda Sep 23 17:32:41 mail deliver(some.user): Module loaded: /usr/lib/dovecot/modules/lda/lib90_cmusieve_plugin.so Sep 23 17:32:41 mail deliver(some.user): maildir: data=/home//some.user/Maildir Sep 23 17:32:41 mail deliver(some.user): maildir: root=/home//some.user/Maildir, index=/home//some.user/Maildir, control=, inbox= Sep 23 17:32:41 mail deliver(some.user): cmusieve: Using sieve path: /home//some.user/sieve/dovecot.sieve Sep 23 17:32:41 mail deliver(some.user): cmusieve: Executing script /home//some.user/sieve/dovecot.sievec Sep 23 17:32:41 mail deliver(some.user): msgid=<72817c95458dbded987b82ec644f7dce(a)red2.co.uk>: rejectedReturn-Path: <andre.rodier(a)red2.co.uk> Here the headers of an email received, and supposed to be auto answered.

I cant see any dovecot file. I have temporary try to use 0777 for home/sieve/maildir folders, but no file is created at all. * Is it the same process used to forward, discard and finally vacation ? * I use virtual file for users on postfix, and I also have a LDAP server for authentication. Do I have something to configure on dovecot to be sure that vacation is working with this configuration ? * As you may have noticed above, mails are redirected to localhost users. ( c.f X-Original-To: some.user(a)red2.co.uk and Delivered-To: some.user@localhost ) Is this can affect the process ? ( Remember that forward and reject is working ). * Is there a way to debug the vacation process ? Thanks for your help. André Rodier.

[Dovecot] Proxying Performance vs imapproxy
by Dan Poltawski 28 Sep '09

28 Sep '09

Hi, I'm planning on a new mail infrastructure which constists of multiple 'frontends' running webmail & public access pop/imap, which would communicate over imap/pop to 'backend mail stores'. My original idea was to run dovecot on the backends, use a predition on the frontends to proxy imap/pop and also run imapproxy in front of webmail [squirrelmail]. I've since read about the dovecot proxying features and it seems to make sense to replace predition in that above scenario. I'm unclear about the benefits of the auth_cache and how it compares to the using imapproxy in front of webmail client? Does it make sense to have authcaching switched on in the proxy and not on the backend server? (Doesn't the authentication just have to happen on the backend server?) Are there any performance benefits to using a proxying server, or is it just for splitting mailstores? thanks for your work, Dan Poltawski

[Dovecot] Upgrading Dovecot on CentOS 4 from 0.99 to 1.x
by Josep L. Guallar-Esteve 28 Sep '09

28 Sep '09

(sorry for my previous message, I sent it by mistake before finishing it) Hello, We have a production mail server running dovecot 0.99 (dovecot-0.99.14-1.rf). We are getting several errors corrected in dovecot 1.x versions: * corrupted inboxes (garbage at beggining of mbox files), * corrupted index files (Error: Corrupted file index /home/jsmith/.imap/Drafts/.imap.index: Sequence 6 not found from binary tree (6 msgs says header)), * others (Error: fcntl() failed with mbox file /var/mail/jsmith: Resource deadlock avoided), etc. I'm planning to upgrade using the instructions found at dovecot's wiki. On http://atrpms.net/dist/el4/ it is offered in 3 different versions: * dovecot 1..0.15-1_73.el4 * dovecot 1.1.19-1_96.el4 * dovecot 1.2.5-0_100.el4 I have a separated test system, where I'll test upgrading from 0.99 to final selected version, to discover any possible gotchas found while upgrading. Two questions: 1. Which version is the recommended to upgrade? I'd like stability and as little problems as possible over anything else, as we have a simple set up. 2. What is the preferred upgrade method? straight upgrade? (099 -> rpm -Fvh dovecot-1.2 ? Or upgrading one release at a time? (0.99 > 1.0 > 1.1 ...) Thank you in advance for any recommendation.

[Dovecot] require SSL certs only for encrypted connections?
by Florin Andrei 28 Sep '09

28 Sep '09

# 1.1.11: /etc/dovecot/dovecot.conf # OS: Linux 2.6.28-14-server x86_64 Ubuntu 9.04 Here's the situation: I have several local clients (Thunderbird) which do not use TLS at all. It's plaintext completely, on port 143, because the connection is local and there are no unauthorized users on this network (it's a home network). I want to keep it that way to keep things simple. Tools / Account Settings / Server Settings: Use Secure Connection: Never Use Secure Authentication: unchecked Until now, this has worked very well. No problems so far. But now I am also setting up IMAPS for remote iPhone clients, with client/server certificates. This is how I generated the certs: http://impetus.us/~rjmooney/projects/misc/clientcertauth.html On the iPhone I uploaded the client.crt file (couldn't import client.p12 for some reason). For Dovecot I am using ca.crt, server.crt and server.key. ssl_listen: *:993 ssl_disable: no ssl_ca_file: /blah/ca.crt ssl_cert_file: /blah/server.crt ssl_key_file: /blah/server.key ssl_key_password: ssl_parameters_regenerate: 168 ssl_cipher_list: ALL:!LOW:!SSLv2 ssl_cert_username_field: commonName ssl_verify_client_cert: yes disable_plaintext_auth: no auth default: mechanisms: plain login ssl_require_client_cert: no ssl_username_from_cert: no I analyzed the connection on 993 with Wireshark and apparently all is good: it's encrypted, I see the certificate exchanges taking place. But I am worried about authenticating the connections from the iPhone and I would like to configure "ssl_require_client_cert: yes" so that a valid certificate is always required. But if I do that then Thunderbird fails to login because it's required a certificate. This is puzzling. I thought that setting would only influence SSL connections. But apparently it also affects plaintext logins from Thunderbird. Is there a way to require a cert from the iPhone TLS connections on port 993, but do not require it from clients connecting to port 143? -- Florin Andrei http://florin.myip.org/

[Dovecot] Segfault in quota-fs plugin
by Brandon Davidson 28 Sep '09

28 Sep '09

Hi all, We recently attempted to update our Dovecot installation to version 1.2.5. After doing so, we noticed a constant stream of crash messages in our log file: Sep 22 15:58:41 hostname dovecot: imap-login: Login: user=<USERNAME>, method=PLAIN, rip=X.X.X.X, lip=X.X.X.X, TLS Sep 22 15:58:41 hostname dovecot: dovecot: child 6339 (imap) killed with signal 11 (core dumps disabled) We rolled back to version 1.2.4, and installed 1.2.5 on a test system - something we'll have to make sure to do *before* rolling new versions into production. Anyway, after examining a few core files from the test system, it looks like the recent changes to the quota plugin (specifically the maildir backend's late initialization fix) have broken the other backends. Stack trace and further debugging are available here: http://uoregon.edu/~brandond/dovecot-1.2.5/bt.txt The relevant code seems to have been added in changeset 9380: http://hg.dovecot.org/dovecot-1.2/rev/fe063e0d7109 Specifically, quota.c line 447 does not check to see if the backend implements init_limits before calling it, resulting in a null function call for all backends that do not do so. Since this crash would appear to affect all quota backends other than maildir, it should be a pretty easy to reproduce. I've attached a patch which seems to fix the obvious code issue. I can't guarantee it's the correct fix since this is my first poke at the Dovecot source, but it seems to have stopped the crashing on our test host. Regards, -Brandon

[Dovecot] Running dovecot master processes across multiple IPs
by Steven F Siirila 28 Sep '09

28 Sep '09

We are running dovecot 1.1.8 and are currently running it with 4 master processes (one for each of the protocols: imap, imaps, pop3, pop3s). The idea was to spread out the load so as to not overwhelm any one master. This has worked well. To take it further, we're contemplating running masters across multiple IP addresses, where the host/service name DNS records would be something like this: imap-server.domain A 10.1.1.1 A 10.1.1.2 A 10.1.1.3 A 10.1.1.4 The default route would either be through the first address (10.1.1.1 in this example) or potentially across all of them in presumably a round-robin fashion. Do you see any problems with this? Has anyone done this? -- Steven F.

[Dovecot] Ubuntu 9.x segmentation fault with vpopmail auth
by Timothy Timmons 28 Sep '09

28 Sep '09

I've been trying for 24 hours now, to get an IMAP server which will autenticate off of vpopmail cdb database and the auth module always segfaults on login. I'm using vpopmail 5.5.0 only because it is the only version which seems to create a dynamically linked version of the library. I tried latest releases dovecot 1.0, 1.1, and 1.2. Also latest mercurial pulls of 1.1 and 1.2. Even old versions of courier-imap and courier-authlib do it, but with these I can try older versions of vpopmail cause they don't require the dynamically linked version of libvpopmail. So I'm thinking it is something with Ubuntu 9.04 and pretty much all third party vpopmail authentication code. Strangely qmail-pop3d works fine with vchkpwd, just I cannot find any IMAP server that will work no matter what combination of vpopmail and version of the IMAP server. If anyone can figure this out I'd greatly appreciate it.

[Dovecot] Sieve: problems installing in different prefix
by Andreas Ntaflos 28 Sep '09

28 Sep '09

Hi list, but mainly Stephan :) when building and subsequently installing the new Sieve plugin I am coming across a small difficulty when it comes to "make install". The libraries lib90_sieve_plugin.* always get installed in the directory /usr/local/lib/dovecot/lda, no matter what "prefix" argument is supplied to "make install". Only the libraries seem affected, not the rest of the Sieve plugin distribution (i.e. sieve, sievec, sieve-test, ...). Background: I like using XStow [1] to manage packages built from source. With XStow one can configure and build software like Dovecot and Sieve as usual (./configure && make) but then install it under a custom directory/prefix, like /usr/local/stow/dovecot-1.2.5. The "prefix" argument for "make install" is used for this, i.e.: make install prefix=/usr/local/stow/dovecot-1.2.5 XStow is then used to create symlinks to the correct places in the file system. For example the Dovecot binary gets installed in /usr/local/stow/dovecot-1.2.5/sbin/dovecot and a symbolic link is created by XStow: /usr/local/sbin/dovecot -> ../stow/dovecot-1.2.5/sbin/dovecot The advantages are clear: installing a software package is a matter of configuring, building and then installing under a custom directory, and letting XStow create symlinks. Updating is as easy as installing the new version in a parallel custom directory and letting XStow update the symlinks. Removing a software package just involves letting XStow remove the symlinks and doing an rm -rf on the custom directory. No more accidentally orphaned files or the need to keep the compiled source distribution around to be able to issue a "make uninstall". Back to the problem: The Sieve source distribution seems to have some hard-coded setting to always install the libraries under /usr/local/lib/dovecot/lda and not honouring the "prefix" argument for "make install". This is probably a libtool issue, but I am not sure. I know my way around the Autotools but here I am a bit lost. Looking at the generated Makefile in dovecot-1.2-sieve-0.1.12/src I can see the following: moduledir = /usr/local/lib/dovecot/ It *should* look like this: exec_prefix = ${prefix} ... moduledir = ${exec_prefix}/lib/dovecot/ This explains why the install prefix is not honoured here. The "moduledir" has already been hardcoded, instead of prefixed. For comparison look at the Dovecot source distribution. Here all libraries are installed correctly under the specified prefix. An example is src/lib-sql. The generated Makefile includes these lines, which are correctly honouring the prefix: exec_prefix = ${prefix} ... moduledir = ${exec_prefix}/lib/dovecot ... #sql_moduledir = $(moduledir)/sql AM_CPPFLAGS = \ -I$(top_srcdir)/src/lib \ -DMODULEDIR=\""$(moduledir)"\" \ $(SQL_CFLAGS) The last few lines seems to make sure that gcc uses the defined moduledir, but as usual generated code is not immediately comprehensible for the casual viewer :) The top-level generated Makefile also contains a correctly defined moduledir: moduledir = ${exec_prefix}/lib/dovecot So, which knobs have to be turned to have the Sieve source distribution use a correct "moduledir" and not a hardcoded path? I hope I could explain the problem correctly and haven't drawn any wrong conclusions here. I will continue to investigate this and maybe even provide a patch if I find a solution but it is probably easier for the maintainer and author of the build system to look at this and determine what to do. Anyway, apologies for this lengthy post. I hope it wasn't too long to read.

[Dovecot] Sieve: redirect and keep action, possible bug
by Andreas Ntaflos 27 Sep '09

27 Sep '09

Hi, Using Dovecot 1.2.4 and the new Sieve implementation in version 0.1.12, I ran into a problem that could indicate a bug in Sieve. The following is a simple script (as generated by Horde's Ingo application) to redirect incoming mail and also keep a copy of the message in the local inbox: if true { redirect "foo(a)example.org"; } if true { keep; stop; } Problem is, it doesn't work as expected: no copy of the message is kept in the local inbox. However, if I explicitly tell Sieve to "fileinto" it works fine: require ["fileinto"]; if true { redirect "foo(a)example.org"; } if true { fileinto "INBOX"; stop; } Is this a bug in Sieve or am I wrong about how "keep" works? Thanks in advance! Andreas -- Andreas Ntaflos Vienna, Austria GPG Fingerprint: 6234 2E8E 5C81 C6CB E5EC 7E65 397C E2A8 090C A9B4

[Dovecot] Dovecot + DRBD/GFS mailstore
by Guy 26 Sep '09

26 Sep '09

Hi guys, I'm looking at the possibility of running a pair of servers with Dovecot LDA/imap/pop3 using internal drives with DRBD and GFS (or other clustered FS) for the mail storage and ext3 for the root drive. I'm currently using maildrop for delivery and Dovecot imap/pop3 with the stores over NFS. I'm looking for better performance but still keeping the HA element I have now with shared storage over NFS. Has anyone had experience with a setup like the one I'm suggesting? What was performance like with Dovecot using GFS? Thanks Guy -- Don't just do something...sit there!

[Dovecot] Apparent corruption of dovecot.uidlist
by AnneWilson 25 Sep '09

25 Sep '09

I have been using Dovecot for about three years, and am currently using version 1.0.7 under CentOS. One of my users can no longer access his Inbox, although he can read mail in other folders. After a fair bit of log-viewing and looking for clues it suddenly began to make a sort of sense. The error message in the logs is Error: IMAP(david): unlink(/home/david/Maildir/cur/cur:2,ST) failed: Is a directory Eventually I came to /home/david/Maildir/dovecot-uidlist and compared it with my own. The second line in the problem account file is 'cur:2,ST. I backed up the file, then deleted that line. Sure enough, I could then open the messages. Unfortunately, when I close KMail I saw the line 'cur:2,ST' added to the end of dovecot-uidlist, and of course I'm back with the error. Can someone please explain to me what is causing this, and how I can correct it? Thanks Anne

[Dovecot] Feature request: 'dovecot-shared' files to be configurable
by Hendrik Pahl 24 Sep '09

24 Sep '09

Hi list, using dovecot in a more complex environment nearly always requires use of ACLs and shared mailboxes/folders. Now, to make life more easy for the users, we can use 'dovecot-shared' files to eable per-user \seen-flagging. Is it possible to make this issue configurable in the dovecot config, something like "always keep a 'dovecot-shared' file in users maildir, even if that mailbox is not shared"? That would be nice, since creating that files by hand is really time-consuming. Or are there any relations which avoid making this issue configurable?
