---------- Forwarded message ---------- From: Vidyasagar Warge <vidyasagar.mailinglists(a)gmail.com> Date: Apr 17, 2007 4:36 AM Subject: dovecot - cas authentication help needed To: cas(a)tp.its.yale.edu Hello All, I am new to CAS & writing my first mail on this mailing list. So please forgive me if I am asking something trivial or stupid :). I am trying to configure dovecote-IMAP server to authenticate the users against CAS through PAM authentication. I found a tutorial here: http://translate.google.com/translate?hl=en&sl=fr&u=http://esup-portail.org… I followed the instructions, but not able to get the authentication running through PAM :(. I googled a lot but didn't found any text on dovecot-pam-casauthentication. If anyone has done it before? and can tell me the steps? Thanks in advance! Regards, Vidyasagar Warge.

[Dovecot] help with static userdb
by Kyle Wheeler 18 Apr '07

18 Apr '07

Hey, This may be a dumb question... I'm trying to set up 1.0 with a static userdb, and I'm getting stuck. I have: userdb static { args = uid=500 gid=500 home=/domains/%d/%n } When I attempt to log in as, say, kyle(a)memoryhole.net (via telnet, so I *know* I'm logging in as that user), the debug log says that it thinks my home directory is "/domains//kyle". I even tried, just to check what might be going on: args = uid=500 gid=500 home=/domains/%u/%d/%n It then thought my home directory was "/domains/kyle//kyle". Can anyone help me? Where might that be getting cleared? ~Kyle -- The more men you make free, the more freedom is strengthened and the ... greater is the security of the State. -- Frederick Douglas, Nov 17, 1864

[Dovecot] lazy_expunge vs mulberry
by Frank Cusack 18 Apr '07

18 Apr '07

I've configured the lazy_expunge plugin exactly like it says on the wiki. I can't seem to configure Mulberry to find the new namespaces. Any hints? I notice that the wiki says to use / as the separator. Mulberry has a setting for this, and the default is '.'. Leaving this as '.' in Mulberry and / in dovecot seems to work fine. (But I still can't access the .EXPUNGED or other namespaces.) Another page on the wiki says that the default separator for maildir is '.'. Why does the lazy_expunge page suggest using '/'? I'm very confused about namespaces. -frank

[Dovecot] Time just moved backwards
by Chaos Engine 18 Apr '07

18 Apr '07

Hi there, I got a daily cron (rdate to local time server) job wich adjusts time and which constantly gives me headache. Every day my dovecot suicides with: "dovecot: Time just moved backwards by 11 seconds. This might cause a lot of problems, so I'll just kill myself now." Of course my onboard clock is constantly off by more than 5 secs. I don't want to abandon time synchronization and I want to use dovecot. Maybe a -HUP signal would do? What do you propose? -- Chaos greets U

[Dovecot] PAM on AIX - resolved
by Stewart Dean 17 Apr '07

17 Apr '07

I previously asked about this problem with pam on IBM's AIX Unix > I get the errmsg: > auth|security:err|error dovecot-auth PAM: load_modules: can not open > module /usr/lib/security/pam_prohibit FWIW, it turned out that the default PAM libraries are 32 bit, while I had compiled DC at 64bit. The /etc/pam.conf lines come standard like this: telnet auth required /usr/lib/security/pam_aix To get 64 bit, you can either change the line like this: dovecot auth required /usr/lib/security/64/pam_aix OR, you can let PAM figure which bit-width library to use dovecot auth required pam_aix Needless to say, it would have been better if the IBM default was the second -- ==== Stewart Dean, Unix System Admin, Henderson Computer Resources Center of Bard College, Annandale-on-Hudson, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035

[Dovecot] keeping indexes in tmpfs
by Justin McAleer 17 Apr '07

17 Apr '07

While doing some testing with converting accounts while simulating incoming mail load (no other pop/imap processes going but 4 processes converting users), we found that we were maxing out the local disk in the server with the index activity. To find out that it was the index activity, I mounted a tmpfs for dovecot to keep indexes on, and the system load dropped from 70 to 3 :) Anyway, Timo and others, do you have any thoughts about keeping indexes on a tmpfs partition? I realize the obvious issues with this: running out of space, and the fact that the partition is lost on reboot. However, we plan to run a cluster of these servers anyway, where we will keep domains/accounts going to a particular server but fail over to one of the others in case of an outage. Recreating the indexes seems pretty trivial when writing to tmpfs anyway, plus we could copy the indexes to disk (restore after reboot) in the case of planned outages... unplanned outages result in another server rebuilding them all anyway. So, I'm looking for non-obvious issues we may have with this approach. I need to do more testing to see how much memory we would actually need to feasibly keep the indexes there, but otherwise is there a good reason not to do this?

If I would actually use my eyes I would see: "Another problem is that although the namespace prefix shows up as a normal looking mailbox, Dovecot doesn't allow subscribing to it because it's not a real mailbox. This will be fixed in later versions." on the wiki page. Nevermind me :) I assume this hasn't been fixed yet?

[Dovecot] Different classes of user
by John Robinson 17 Apr '07

17 Apr '07

Hello list! Only recently joined, please excuse me if this is a stupid question. I'd like to have 2 classes of user: those with shell accounts, and those without. They'll all have "real" accounts, for which the password can be checked with PAM. I've set up SSL too. What I want to arrange is for users with shell accounts not to be succeed in logging in to Dovecot without using TLS/SSL. I'll have to allow unencrypted logins (for non-shell users), but I want to reject/refuse such a login from someone with a shell account. I've already made my exim do this, with the following logic in my authenticator there: if (pam auth ok) and ((tls) or (user's shell not listed in /etc/shells)) I haven't worked out how to make Dovecot do this, yet. So far I just tried using * as the PAM service name, in the hope that not only would pop3 or imap get passed through, but pop3s and imaps might, and I had a line in my /etc/pam.d/imap and pop like this: auth required pam_succeed_if.so debug shell notin /bin/bash:/bin/sh which worked, but unfortunately also got used for imapS logins. Then I realised this was likely to be the wrong thing anyway, because it would presumably only cover IMAPS on port 993, and not IMAP+TLS on the usual port 143. So I've had a go but got it wrong. What should I do to get it right? Cheers, John.

Hello, I have upgraded to Dovecot 1.0.0, I saw a lot of error in the dovecot.log file: Timeout while waiting for lock for transaction log file /fs/example.com/joewong/Maildir/dovecot.index.log where /fs is a NFS mounted directory. What can be the cause of this problem? How to prevent this from happening? Thanks! - Joe

[Dovecot] Maildir, INDEX, and folders
by Troy Engel 17 Apr '07

17 Apr '07

I'm reading the wiki et el. regarding indexes, but can't come up with a coherent answer to the setup and what will happen. I want to take the indexes and move them off of NFS (~/Maildir) and place in /var/spool/dovecot/indexes, but not have to hand create everything (user homes, mail folders) So, I create a parent folder /var/spool/dovecot/indexes that has the appropriate permissions for writing by all users/dovecot. If I then set: mail_location = maildir:~/Maildir:INDEX=/var/spool/dovecot/indexes/%1u/%u ...will the dovecot daemon(s) automagically create (A) the parent user folders (i.e. .../indexes/t/tengel/)(1), and (B) the necessary subfolders for all the child folder indexes? (i.e. .../tengel/.Lists.Dovecot/) Most of the doc info seems to revolve around moving your indexes if you use mbox, I'm a little fuzzy on what happens with Maildir when you attempt this. thanks! -te (1) in our setup, initially user's home folders are created on an admin server -> NFS that is not the mail server, so Dovecot needs to create the home & index folders on it's own at runtime. -- Troy Engel | Systems Engineer Fluid, Inc | http://www.fluid.com

[Dovecot] mail_log plugin
by Phillip T. George 16 Apr '07

16 Apr '07

Hello all, Is there any way to add additional options for the mail_log plugin? Specifically, I'm wanting to make it so IMAP copy commands will show the source filename and/or the user's IP address. Is this possible? If there are docs for this info, feel free to point me to it. -Phillip

[Dovecot] LDA problem

Hi, I am using dovecot deliver as lda for sendmail. My problem is that when a user account is over quota, deliver program sends message in the logs, but the message is not bounced back to sender informing that their is disk quota problem at the recipient side. Further message remains in the mail queue. Details are below. Plz suggest how to figure out the problems: 1. Message should be removed from queue if quota is exceeded 2. Sender should get a proper response.

[Dovecot] dovecot pam const
by Frank Cusack 15 Apr '07

15 Apr '07

In passdb-pam.c, I found some bits about const with some PAM data types. Rather than check for each vendor of PAM, better to check for actual const usage ... some vendors have changed const-ness between releases. Also, actually testing constness is great for supporting new implementations that may come out. Here is the autoconf test I use in pam_otp_auth: --8<-- # Check PAM headers for brokenness otp_CFLAGS="$CFLAGS" # save CFLAGS="$CFLAGS $EXTRA_CFLAGS -Werror" # Linux-PAM has (incorrectly) overdone const AC_MSG_CHECKING(for extra const in PAM headers) AC_TRY_COMPILE([#include <security/pam_appl.h>], [ pam_handle_t *pamh = NULL; char *item; pam_get_item(pamh, PAM_SERVICE, (void **) &item); ], [ AC_MSG_RESULT(no) DEFINES="$DEFINES -DPAM_GET_CONST=" ], [ AC_MSG_RESULT(yes) DEFINES="$DEFINES -DPAM_GET_CONST=const" ]) # Solaris PAM has (incorrectly) underdone const AC_MSG_CHECKING(for missing const in PAM headers) AC_TRY_COMPILE([#include <security/pam_appl.h>], [ struct pam_conv *conv = NULL; struct pam_message *msg; struct pam_response *resp; conv->conv(1, &msg, &resp, conv->appdata_ptr); ], [ AC_MSG_RESULT(yes) DEFINES="$DEFINES -DPAM_CONV_CONST=" ], [ AC_MSG_RESULT(no) DEFINES="$DEFINES -DPAM_CONV_CONST=const" ]) CFLAGS="$otp_CFLAGS" # restore --8<-- And then I do pam_get_item(..., (PAM_GET_CONST void **) arg); pam_get_user(..., (PAM_GET_CONST void **) arg); conv(..., (PAM_CONV_CONST struct pam_message **) arg, ...); -frank

[Dovecot] Moving Maildir files from multiple Dovecot installs
by craig carriere 15 Apr '07

15 Apr '07

I currently have Dovecot running on a SuSE SLES 10 mail server with postfix as the MTA and a number of real linux users. I have postfix delivering to Maildir records. We are going to convert to a virtual user/domain system with PostfixAdmin. I have checked out all of our settings and they appear to work well except for a problem with authenticating against mySQL using MD5-Crypt; plaintext works well however. My question is how to transfer the maildir files from the real users Maildirs to the created virtual users. When creating a mail user PostfixAdmin will create the maildir directory. Once this is created can I simply rsync the complete old directory including the dovecot files to the new mailbox? Sorry for the newbie question. Many Thanks --------------------------------- We won't tell. Get more on shows you hate to love (and love to hate): Yahoo! TV's Guilty Pleasures list.

[Dovecot] 2 mysql dbs or 2 types of encryption
by Ken Anderson 14 Apr '07

14 Apr '07

Just upgrading to 1.0.0 and I'm trying to switch from PAM (using pam-mysql) to a direct mysql query from dovecot, and I've got both md5crypt and crypt passwords in a password db. http://wiki.dovecot.org/Authentication/PasswordSchemes seems to indicate that I have to pick 1, but that is per auth-worker, right? So, I created 2 auth workers using 2 dovecot-sql config files specifying different default encryption schemes and it seems to work. Is there any problem with this, other than a small bit of overhead for 2 queries if the first doesn't hit? Thanks, Ken Anderson Pacific.Net

This minor problem still exists in the current version. http://www.dovecot.org/list/dovecot/2006-December/018251.html It's my own fault, I kept meaning to test one of the latest versions before the 1.0 release and never got around to it. Oh well, just mentioning it so it stays on the list of things to do. 1.0.0 update from RC15 went smoothly here. Thanks, Mark Nienberg

[Dovecot] Convert mbox to maildir
by Héctor S. Mendoza O 14 Apr '07

14 Apr '07

Hello all Ive installed a new Server with dovecot, started using it and had no problems until I noticed that I couldnt create sub-sub-folders on my imap account, Ive read for the past two days info on how to convert and I know now that instead of using mbox I need to user maildir, the issue is now to convert mbox to maildir, on the various searches I did, I found the convert wiki page (http://wiki.dovecot.org/Plugins/Convert) followed the instructions there and no luck, I always end up with an error: Eopen(/.temp.chihuahua.intranet.acorporativa.com.mx.21409.1089e702ee50f317) failed: Permission denied Error: imap dump-capability process returned 89 If I remove the line convert_mail = mbox:~/mail:INBOX=/var/mail/%u it starts correctly but I see no e-mails and no conversion takes place, since its a production server Ive reverted all changes and had to add a line (mail_location = mbox:~/mail:INBOX=/var/mail/%u) to be able to see my e-mails again. Ive tried stopping dovecot, making the changes and trying dovecot n to see the configuration, but with the same results. Any ideas on what Ive been doing wrong?

[Dovecot] 1.0.rc32 released
by Timo Sirainen 13 Apr '07

13 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.

[Dovecot] dovecot forward multipart problem
by Samuel HAMEAU 13 Apr '07

13 Apr '07

Hi, I experience problems everytime i forward a mail (basically, when forwarding an email containing an attachement). I'm using thunderbird (it does the same with outlook clients) with the forward parameter "as attachement" instead of "inline". (Using the inline parameters works fine). When i forward a mail with attachements (eg a jpeg file), the attachements file is displayed in base64 instead, and is impossible to detach/save. I'm using dovecot 1.0.rc22-1 (debian package) on debian etch, x86 SMP box with maildir format on a ext3 partition. I'm using postfix currently 2.3.4-3, i have tried different version of dovecot (from rc16 i think) and postfix (from 2.2.?) and i suspect the deliver to be the origin of the problem. I think it is the same problem than here http://dovecot.org/pipermail/dovecot/2006-July/014786.html , my "From" headers are badly duplicated. Could this be fixed before the dovecot 1.0 release ?

[Dovecot] LDA sieve plugin [patch]
by Uldis Pakuls 13 Apr '07

13 Apr '07

Hi all. I spent some time testing Dovecot's LDA sieve plugin and found problem with "notify" method. In fact it always returns "generic sieve error"... and thus produces bounce messages like this: ----- Your message was automatically rejected by Dovecot Mail Delivery Agent. The following reason was given: Unknown error ---- Deliver logs error: "generic sieve error", but otherwise server reports "notify" method as supported. The problem is: original code was taken from curys sieve and requires "notifyd", as sieve runs 'chrooted' and can't access external binaries like "sendmail". communications with notifyd is done via socket. Thus I wrote pacth, which ads "notify" functionality to dovecot's sieve plugin, at less "notify:mailto" method. cyrus originally contains null, log and zephyr methods. null and log is useless with dovecot, zephur is cyrus specific... RFC docs says there is 3 available methods SMS, XMPP and MAILTO: ------ method can be an SMS URI [SMS-URI <http://ietfreport.isoc.org/idref/draft-ietf-sieve-notify/#ref-SMS-URI>] containing a phone number, or an XMPP [XMPP <http://ietfreport.isoc.org/idref/draft-ietf-sieve-notify/#ref-XMPP>] URI containing an XMPP identifier [XMPP-URI <http://ietfreport.isoc.org/idref/draft-ietf-sieve-notify/#ref-XMPP-URI>] The supported URI values will be site-specific, but support for the [MailTo <http://ietfreport.isoc.org/idref/draft-ietf-sieve-notify/#ref-MailTo>] method is REQUIRED in order to insure interoperability. If a URI schema is specified that the implementation does not support, the notification MUST cause an error condition. Sieve scripts can check the supported methods using the "valid_notify_method" test to be sure that they only use supported ones, to avoid such error conditions. ------ as SMS-URI and XMPP methods are not included in cyrus sieve version, they are not available in dovecots plugin too. [any ideas, sample code how to implement them?] BUT... WARNING All this will not work if you have "mail_chroot" setting enabled in dovecot.conf; chrooted process can't access required external binaries. DOT USE THIS PLUGIN WITH "mail_chroot" SENTIG ENABLED! Actualy it is not sieve plugin problem only - its LDA problem... it can't send bonce messages, do forwards etc. Question to Timo: Do You have ideas how to fix it? My be disable chroting for LDA at all? or do it "cyrus way" - move all calls to external binaries to sepreate, non chrooted process? For delivery agent it is requred to be able send bounces and notifications... do forwards. Uldis

[Dovecot] convert plugin created maildirfolder file in root maildir directory
by Justin McAleer 12 Apr '07

12 Apr '07

I've noticed that if a user's maildir gets created by deliver or pop/imap without the convert plugin running, the maildir structure is fine (no maildirfolder file). But, if a user gets converted, there is a maildirfolder file in the user's base maildir directory. As far as I can tell, that doesn't cause any problems, but I just wanted to mention it. I've looked at the code for a while but didn't find why it behaves differently.

[Dovecot] Connection refused with auth-master after upgrading to Dovecot 1.0 rc 28

[Dovecot] Comment from OpenLDAP developer regarding "deferring operations"
by Ben Beuchler 12 Apr '07

12 Apr '07

I received this response from a member of the OpenLDAP core team when asking about meaning of the deferred operations I was seeing. Is it possible that this is what I'm seeing, Timo? -Ben --------------------------------------------- I'd note that if your client is performing search + bind on the same connection in an asynchronous manner, then the server behavior as per RFC4511 is undefined, since a server is not supposed to be willing to handle operations intermixed with binds until a bind is concluded. That is, any operation can be multiplexed on a single LDAP connection __except__ binds, which must be serialized. A more appropriate client for that type of operations would need to use at least 2 connections, one for searches and one for binds, and the one for binds should take care of either performing synchronous binds, or in any case to wait for response to a bind before performing another. In case of failure (e.g. timeout) while waiting for bind response, the connection should be trashed (see ldap_unbind_ext(3)) and recreated. This is what is done, for example, by slapd-ldap(5). p.

[Dovecot] Dovecot Assertion on mail server with POP3 and LDAP authentication
by Tim Alberts 12 Apr '07

12 Apr '07

Running two Fedora 6 systems with all the latest updates as of a week ago. One system is the mail server (sendmail, dovecot), the other is the master (open)LDAP server with the mail server running a slave LDAP instance. The problem I'm having is the client pop3 users are frequently being told their passwords aren't correct by their email clients (Outlook, Eudora). They try again, a couple times and eventually it works. I've seen it on my own account and when I test their accounts, occasionally it just doesn't take the password. I've only had this trouble since I implemented the LDAP authentication. Checking through the server maillog, I see the following entry: Apr 4 08:44:38 msi2 dovecot: auth(default): dovecot-auth: ../../../libraries/liblber/io.c:491: ber_get_next: Assertion `ber->ber_buf == ((void *)0)' failed. Apr 4 08:44:38 msi2 dovecot: auth(default): pam(secretuser,192.168.0.200): Child process died Apr 4 08:44:38 msi2 dovecot: auth(default): PAM: Child 14564 died with signal 6 Apr 4 08:44:38 msi2 dovecot: pop3-login: Aborted login: user=<secretuser>, method=PLAIN, rip=192.168.0.200, lip=192.168.0.11 This seems to point out that dovecot is the problem, but again, I didn't have this trouble until I implemented the LDAP authentication. So my question is, anyone know a solution? If not, anyone got a suggestion of where I should look for more clues or support? Or any suggestions at all? Thanks for any help. Following is the dovecot version and configuration [root@msi2 ~]# dovecot --version 1.0.rc15 [root@msi2 ~]# dovecot -n # /etc/dovecot.conf protocols: pop3 listen: login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/pop3-login mail_executable: /usr/libexec/dovecot/pop3 mail_plugin_dir: /usr/lib/dovecot/pop3 pop3_client_workarounds: outlook-no-nuls oe-ns-eoh auth default: passdb: driver: pam userdb: driver: passwd [root@msi2 ~]#

[Dovecot] Building Dovecot to link against alternative libldap
by Ben Beuchler 12 Apr '07

12 Apr '07

I'm running Dovecot on an Ubuntu (Edgy) box. I'd like to link dovecot against the latest stable version of the OpenLDAP libraries instead of the system defaults. I can't really replace the existing libraries as other packages rely on them. If this didn't use libtool, I would be able to influence the runtime linker by manipulating -rpath and -L. I can't seem to figure out how to get this to work with Dovecot's libtool-based build. The system libldap_r.so.2 lives in /usr/lib My libldap_r.so.2.3 lives in /usr/local/lib Anyone have any pointers? -Ben

[Dovecot] Problems with (probably) Dovecot
by Frank Neps 11 Apr '07

11 Apr '07

Hello altogether, I've got Dovecot 0.99 installed on a Suse Linux 9.2 system, together with Postfix. I need to upgrade that server in the near future to new hardware and new versions, but at the moment it would be great, if I could find the solution for the following problem without upgrading. Unfortunately I didn't find a solution in Google. The system has enough memory and disc space, it was running for about 4 or 5 years without problems now. Trying to access my messages on the server via IMAP protocol using Outlook (2000 or 2002 or 2003) leads to an error message "Invalid messageset: xxxxxxxx" (where xxxxxxxx is a changing number). No data is displayed, the headers are not updated. Squirrelmail says, that the messages are not available any more. And Thunderbird joins in with Outlook and also tells me something about an invalid messageset. For some reasons (and some messages, not all) Kontact / Kmail does not give me error message, however, my main system is not a Linux one and therefore I'd like to get that fixed, if possible. Somewhere in Google I found a note about IMAP index files, which may be corrupt and need to be rebuilt, but I didn't find any Index files, I must admit. Any idea how to solve that? Thanks in advance and best regards, Frank

[Dovecot] rc31 -> "deferring operation: binding"
by Ben Beuchler 11 Apr '07

11 Apr '07

I hate to bring up anything that might delay 1.0, but the behavior I'm seeing is rather... weird. I'm running rc31, using "userdb static" and "auth_bind=yes". With rc1 (what I had been running) I would occasionally get some "deferring operation" complaints from LDAP, but very rarely. Every now and then it would start to throw "deferring operation: pending operations" and stop authenticating. Digging through the Changelog indicated you've made considerable updates to the auth_bind code, apparently to eliminate just such problems, so I upgraded. Now I'm running rc31 and my OpenLDAP logs are throwing an error like this every few seconds: Apr 9 19:56:42 swizzle slapd[1626]: connection_input: conn=6696168 deferring operation: binding This appears to happen with around every 3rd or 4th bind request. Sometimes it happens with the anonymous requests, sometimes with the auth bind request. As I understand it, the new auth_bind code is extremely careful about flushing all pending operations before attempting to perform the authentication bind. If that's the case, any idea why OpenLDAP is deferring the binding operations so frequently? So far it hasn't caused any login problems, but it's quite disconcerting given the expected behavior described in the Changelog. Any thoughts? -Ben cliff:/opt/dovecot/etc root# ../sbin/dovecot -n # /opt/dovecot-1.0.rc31/etc/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s ssl_cert_file: /etc/ssl/certs/mcad.edu.rapidssl.crt ssl_key_file: /etc/ssl/private/mcad.edu.rapidssl.key disable_plaintext_auth: no shutdown_clients: no login_dir: /opt/dovecot-1.0.rc31/var/run/dovecot/login login_executable(default): /opt/dovecot-1.0.rc31/libexec/dovecot/imap-login login_executable(imap): /opt/dovecot-1.0.rc31/libexec/dovecot/imap-login login_executable(pop3): /opt/dovecot-1.0.rc31/libexec/dovecot/pop3-login login_greeting: Line forms at the rear. login_greeting_capability(default): yes login_greeting_capability(imap): yes login_greeting_capability(pop3): no login_processes_count: 5 verbose_proctitle: yes first_valid_uid: 5000 last_valid_uid: 5000 first_valid_gid: 5000 last_valid_gid: 5000 mail_location: maildir:/mail/mcad.edu/%u/Maildir/ maildir_stat_dirs: yes maildir_copy_with_hardlinks: yes mail_executable(default): /opt/dovecot-1.0.rc31/libexec/dovecot/imap mail_executable(imap): /opt/dovecot-1.0.rc31/libexec/dovecot/imap mail_executable(pop3): /opt/dovecot-1.0.rc31/libexec/dovecot/pop3 mail_plugin_dir(default): /opt/dovecot-1.0.rc31/lib/dovecot/imap mail_plugin_dir(imap): /opt/dovecot-1.0.rc31/lib/dovecot/imap mail_plugin_dir(pop3): /opt/dovecot-1.0.rc31/lib/dovecot/pop3 pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv auth default: mechanisms: plain login user: dovecot-auth passdb: driver: ldap args: /opt/dovecot/etc/dovecot-ldap.conf userdb: driver: static args: uid=5000 gid=5000 socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master:

[Dovecot] Moving maildir folders between different RC dovecot machines
by Francisco Reyes 11 Apr '07

11 Apr '07

Is it ever necessary to delete any of the dovecot files when moving between machines from different RC versions? I read all the RC notes from RC15 to 31 and didn't see any notes about this, but wanted to be completely sure. Have some domains that I need to move from a RC15 machine to a RC29 machine. Also later this month we plan to ugprade from RC15 to Release 1.. when it is out shortly.

[Dovecot] Having a problem with mbox/inbox
by Nick Le Mouton 11 Apr '07

11 Apr '07

Hi, I've just installed dovecot on a RHEL 4 server. I'm using postfix as my MTA. Everything seems to work well when I have a home dir for the user, but I don't like to clutter up my /home/ dir with dirs for users that will never use them (other than mail). Is there no way to just use /var/mail/user (I think in mbox format?). I have no interest at this time of using IMAP, this is purely for POP3. Thanks Nick

[Dovecot] error creating subfolders
by John Harper 10 Apr '07

10 Apr '07

I'm running rc31 and I've come across a weird little error in creating subfolders that's only apparent in a specific situation. I recently moved our entire campus from UW to dovecot, and as part of that migration, and following the wiki, I have some namespaces: ##default namespace namespace private { separator = / prefix = inbox = yes } #for backwards compatibility: namespace private { separator = / prefix = mail/ hidden = yes } namespace private { separator = / prefix = ~/mail/ hidden = yes } which absorb the typical configuration previously used wherein the email client had the imap server folder set to "mail/" or similar, and which still remains on most clients. All of this works perfectly fine, and all users see their mail folders properly. Currently everyone is still in mbox format, and as far as I can tell, users can also create email folders without problems (ie single files in the file system containing messages). But one user discovered that it does not work to create folder containers (ie directories in the filesystem) that would contain other email folders, no matter how one appended / or checked the right box (or having me add the tb-extra-mailbox-sep client workaround -- they're using Thunderbird). Their client config still had mail/ as the server imap directory, and when I cleared that out, then everything worked perfectly. So it's a bit weird that everything works fine with the namespaces, except the one operation of creating the subfolder.

[Dovecot] Dovecot 1.0rc30 message ownership set as root mail
by Mel Llaguno 10 Apr '07

10 Apr '07

I've compiled the latest release candidate of dovecot and I am encountering a strange problem when mail is delivered. I have my installation configured to use Maildir. When messages arrive, they are placed in the correct user directory, but the ownership for individual messages is set to root and the group set to mail. This prevents these messages from being displayed in my client. The error message logged is as follows: dovecot: Apr 08 13:11:08 Error: IMAP(mel): open(/home/mel/Maildir/cur/_d2F.eyKGGB.mjolnir:2,) failed: Permission denied The file permissions for the message are as follows: -rw------- 1 root mail 1805 2007-04-08 13:02 _AqG.VxTGGB.mjolnir:2, I also noticed that the log file in the root Maildir also has the same ownership assigned (not the user's uid/gid). Unless something has changed in dovecot.conf, this behavior is somewhat unexpected. I've included my config file in case there is something obvious that I am missing: base_dir = /var/run/dovecot protocols = imaps protocol imap { listen = imap.domain.com ssl_listen = 0.0.0.0:993 imap_client_workarounds = outlook-idle delay-newmail } disable_plaintext_auth = yes shutdown_clients = yes log_path = /var/log/dovecot.log ssl_disable = no ssl_cert_file = /etc/ssl/certs/imap.domain.com.crt ssl_key_file = /etc/ssl/certs/imap.domain.com.key login_dir = /var/run/dovecot/login login_chroot = yes login_user = dovecot login_process_per_connection = yes login_processes_count = 8 login_max_processes_count = 32 verbose_ssl = yes mail_location = maildir:/home/%u/Maildir:INBOX:/var/mail/%u mail_full_filesystem_access = no mail_save_crlf = no verbose_proctitle = yes max_mail_processes = 128 maildir_copy_with_hardlinks = yes mmap_disable = no lock_method = fcntl umask = 0077 auth default { mechanisms = plain passdb shadow { args = /etc/shadow } userdb passwd { args = /etc/passwd } } If anyone could help clarify this behavior, it would be greatly appreciated.

[Dovecot] "TLS handshake" errors, frozen IMAP
by Ben Beuchler 10 Apr '07

10 Apr '07

Another new issue has cropped up with my rc1 -> rc31 upgrade: This morning, right around the typical morning email surge, Dovecot stopped accepting new IMAP connections. I didn't get a chance to do much troubleshooting and a restart of Dovecot fixed it. The only thing I've been able to find in the logs is a bunch of entries like this one: Apr 10 09:11:36 cliff dovecot: imap-login: Disconnected: rip=150.253.80.90, lip=150.253.10.10, TLS handshake Apr 10 09:11:36 cliff dovecot: imap-login: Disconnected: rip=150.253.80.208, lip=150.253.10.10, TLS handshake Apr 10 09:11:37 cliff dovecot: imap-login: Disconnected: rip=150.253.91.156, lip=150.253.10.10, TLS handshake And a few like this: Apr 10 09:17:48 cliff dovecot: imap-login: Disconnected: Shutting down: rip=66.93.16.227, lip=150.253.10.10, TLS handshake Any idea what that might indicate? -Ben

[Dovecot] What are the Key DC executables
by Stewart Dean 10 Apr '07

10 Apr '07

Back a year ago, I asked what the key DC executables where that I had to bring from my compile host to the production imap server to install or upgrade DC. I was told: dovecot, dovecot.conf, dovecot-auth, imap & imap-login I recently got DC up and running unencrypted and that worked fine. Then I tried to enable SSL and the logs said I was missing /usr/local/libexec/dovecot/ssl-build-param, which I located in the build tree under ./src/master.

[Dovecot] /etc/passwd authentication anomalies

10 Apr '07

I am using the base AIX Unix authentication with NIS. There is a base /etc/password file (though the passwords are in a funny, IBM-peculiar file, /etc/security/passed) of just 18 lines...since NIS is in use, the last line is the standard for-anything-you-don't-find-here-try NIS indicator: +::0:0::: When I start up DC, I get these error massages: Apr 9 14:44:59 mercury mail:err|error dovecot: auth(default): passwd-file /etc/passwd: User root has invalid UID 0 Apr 9 14:44:59 mercury mail:err|error dovecot: auth(default): passwd-file /etc/passwd: User kmem has invalid GID 0 Apr 9 14:44:59 mercury mail:err|error dovecot: auth(default): passwd-file /etc/passwd: User ipsec has invalid GID 0 Apr 9 14:44:59 mercury mail:err|error dovecot: auth(default): passwd-file /etc/passwd: User + has invalid UID 0 This is a niggle, but is there something I should do differently, or is DC just annoyed at what IBM has done with /etc/passwd? -- ==== Stewart Dean, Unix System Admin, Henderson Computer Resources Center of Bard College, Annandale-on-Hudson, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035

[Dovecot] AFS maildirs & GSSAPI?

10 Apr '07

I saw some stuff about AFS maildirs awhile back, and dovecot seems happy being running via ssh from offlineimap with :INDEX=/tmp/dovecot-%u, but what I'd really like to know is has anyone got a functional dovecot installation with AFS and GSSAPI sasl support that gets the correct users's AFS tokens?

[Dovecot] Request for additional logging
by Richard Stockton 10 Apr '07

10 Apr '07

Hi Timo, First, thanks very much for dovecot, you are doing a fine thing making it open source, and it is working very well here. It would be helpful to me if there were more logging options available. For example, I would like to see a record of each email deleted, with the filename (if maildir), and size in the log. I haven't been able to find much documentation on logging at all. Have I just not been looking in the right place? If so, I would appreciate any enlightenment offered. Thanks in advance, - Richard

[Dovecot] PAM question

I get the errmsg: auth|security:err|error dovecot-auth PAM: load_modules: can not open module /usr/lib/security/pam_prohibit That file is 444 root:security What is wrong here? Also, I'm using plain UINX authentication, but PAM keeps trying to run. How do I turn it off? I'll probably eventually want to use PAM; how do I get it to look in /etc/pam.conf instead /etc/pam.d...or will it find it automatically? -- ==== Stewart Dean, Unix System Admin, Henderson Computer Resources Center of Bard College, Annandale-on-Hudson, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035

[Dovecot] Lock file issues
by Paul Hamby 09 Apr '07

09 Apr '07

First off, just want to say Dovecot is great! We have been using it for several months now in a fairly large installation with only a few problems. We are running 1.0.rc28 on three servers with 3 Horde/IMP boxes talking to Dovecot. The user's home dirs are located on an NFS server and the indexes are stored in their Maildirs. I have mmap_disable=yes and lock_method=dotlock in dovecot.conf. We have not implemented anything to direct users to the same server as is recommended per the Wiki. I have been trying to avoid this, as the best way I could see to do it would be to put in an IMAP proxy (Perdition?) and I just wanted to keep it as simple as possible if I could. The problems we have been having are due to dovecot.*.lock files not being cleaned up. This issue presents itself as a user not being able to login via the webmail interface. The logfile will contain something similar to the following: Apr 3 08:37:51 app02 dovecot: IMAP(user): Corrupted transaction log file /mail_home3/j/ji/user/Maildir/dovecot.index.log: end_offset (23440) > current sync_offset (23368) Apr 3 08:37:51 app02 dovecot: IMAP(user): file mail-index-sync-update.c: line 40 (mail_index_sync_update_log_offset): assertion failed: (prev_offset >= map->hdr.log_file_int_offset || prev_seq > map->hdr.log_file_seq) Apr 3 08:37:51 app02 dovecot: IMAP(user): Raw backtrace: imap [0x80a8c1a] -> imap [0x80a873f] -> imap [0x8091fcf] -> imap(mail_index_sync_update_index+0x2a1) [0x80935c5] -> imap(mail_index_sync_commit+0xbf) [0x8091c9f] -> imap(maildir_sync_index_finish+0xc4) [0x8065fbc] -> imap [0x8066851] -> imap(maildir_storage_sync_init+0x4a) [0x80669b2] -> imap(mailbox_sync_init+0x15) [0x809c9ed] -> imap(imap_sync_nonselected +0x17) [0x8060ac3] -> imap(_cmd_select_full+0xc3) [0x8059893] -> imap(cmd_select+0x13) [0x80599fb] -> imap [0x805b12e] -> imap [0x805b251] -> imap(_client_input+0xc3) [0x805b323] -> imap(io_loop_handler_run+0x184) [0x80ae1c0] -> imap(io_loop_run+0x1d) [0x80ad73d] -> imap(main+0xa5) [0x80626b1] -> /lib/libc.so.6(__libc_start_main+0xbb) [0x4003414f] -> imap(chroot +0x31) [0x80568d1] Apr 3 08:38:01 app02 dovecot: IMAP(user): Transaction log file /mail_home3/j/ji/user/Maildir/dovecot.index.log: marked corrupted Apr 3 08:38:01 app02 dovecot: IMAP(user): Transaction log file /mail_home3/j/ji/user/Maildir/dovecot.index.log.2: marked corrupted A directory listing of the Maildir shows the dovecot lock files: -rw------- 1 user users 0 Apr 3 2007 dovecot-uidlist.lock -rw------- 1 user users 360 Apr 3 2007 dovecot.index -rw------- 1 user users 32768 Apr 3 2007 dovecot.index.cache -rw------- 1 user users 24 Apr 3 2007 dovecot.index.log -rw------- 1 user users 11 Apr 3 2007 dovecot.index.log.lock -rw------- 1 user users 360 Apr 3 2007 dovecot.index.tmp While I can't login via the IMP web interface as that user, I am able to initiate an IMAP session via telnet. I can login, but as soon as I try a " select INBOX" it just appears to hang. I have attached the output of 'strace -p pid' of this IMAP session, which shows that it appears to be in a loop (statting the lock file?) for 244 seconds (seems to be consistent, tried it three different times) before it continues and gives me the INBOX. This happens for every subsequent command as well (Fetch, etc.) Once I log out, the lock files are not removed. I have to remove the lock files for the user to be able to log in via the web interface. Please let me know if I need to provide more information. Paul Hamby

[Dovecot] IP Tables block for POP3 attacks with Dovecot
by Pete Dubler 08 Apr '07

08 Apr '07

Has anyone implemented a script to block IPs which are attacking on POP3 ports using dovecot logs to indicate repetitive failed login attempts? sshblack does this nicely for ssh (port 22) attacks by monitoring the /var/log/secure file. I am considering rewriting this to POP3 port (110), but if it has already been done, I sure don't need the practice. Thanks!

[Dovecot] chdir failed, but requires group permissions
by Brent Nesbitt 08 Apr '07

08 Apr '07

Using Debian Etch package dovecot-common and dovecot-pop3d, based on 1.0.rc15-2 My home directories are set up with 770 permissions as follows: /home/<group name>/<user name> Using this method, users MUST be a member of the appropriate group to access their own home directory. If they are not, they can't chdir past /home. This appears to kill dovecot with a "chdir failed with id xxxx: Permission Denied" error, immediately after authenticating a pop3 user. I was able to make a user the owner of the <group name> directory, and dovecot succeeded But when the <group name> directory is owned by <group name>:<group name> and the user is a member of the group - the process dies. Any suggestions?

[Dovecot] SQL mail storage
by Timo Sirainen 08 Apr '07

08 Apr '07

I wasted some time yesterday and today implementing a SQL storage plugin. It seems to be working, but: - Saving new messages is done in a regular INSERT statement, which is bad. PostgreSQL has at least this COPY TO command which could be used instead. - It breaks in stress testing - It's not that well optimized. Especially it could support caching some commonly requested fields (same as dovecot.index.cache file). - Currently works only with PostgreSQL. Nothing is committed to CVS yet. I'm not sure if I should even do that. I'm not sure if those lib-sql API changes were that great. Maybe there's a better way.. If you're interested in trying it, you need the latest CVS HEAD sources and these patches: http://dovecot.org/patches/sql-storage-changes.diff http://dovecot.org/patches/sql-storage-plugin.diff The SQL schema is in src/plugins/mail-sql/schema.sql file. It creates a "tss" named user by default, so you might want to modify that. :) Then set: mail_location = sql:pgsql:host=localhost dbname=mails user=mailuser password=foo mail_plugins = mail_sql

[Dovecot] ssl connections frozen, client times out

[Dovecot] Fully virtualized w/ postfix?
by tquidca＠gmail.com 08 Apr '07

08 Apr '07

Hi folks, I've poked through the archives and google and have not seen how do do this. Is it possible to virtualize ALL emails on a system? That is, I want delivery only to e.g. /var/mail/vmail/domain.tld/user/Maildir/, and for authentication & userdb to: 1) Try /etc/passwd, and if someone is there, automatically append the "default" domain, otherwise, 2) Authenticate off a mysql db or similar. Is this kind of "fallthrough" user lookup and auth. possible with dovecot? I assume the delivery can probably be done by just telling postfix to use dovecot as the local delivery agent. Thanks for your help! --JB

[Dovecot] Inbox inside the mail location
by guenther 07 Apr '07

07 Apr '07

I recently had some scary experience with the Inbox being stored in the default /var/mail dir, and I believe it would be a better idea to keep the Inbox next to any other mail in the users $HOME. mail_location = mbox:~/.mail:INBOX=~/.mail/INBOX This is what I used for a quick test, and actually would love to use in production soon. Based on the test, it just does exactly what I want. :) However, I'd like to confirm what I see is how it is expected to work. Since the Inbox with this layout is is part of the ~/.mail dir just like any other mbox file (or subdir), I am concerned with getting a "second" Inbox mail folder in the client. I did not, which is great. So, is this expected behavior, and the Inbox mbox file actually being the Inbox and only the Inbox? Will it always be excluded from the list of IMAP mail folders? Also... Thanks for this great IMAP server! I migrated many moons ago, beginning with some 0.9x version I don't exactly recall, and it just works. Migration has been a smooth experience too, and I haven't had any issue yet. guenther -- char *t="\10pse\0r\0dtu\0.@ghno\x4e\xc8\x79\xf4\xab\x51\x8a\x10\xf4\xf4\xc4"; main(){ char h,m=h=*t++,*x=t+2*h,c,i,l=*x,s=0; for (i=0;i<l;i++){ i%8? c<<=1: (c=*++x); c&128 && (s+=h); if (!(h>>=1)||!t[s+h]){ putchar(t[s]);h=m;s=0; }}}

[Dovecot] 1.0.rc30 released
by Timo Sirainen 07 Apr '07

07 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

[Dovecot] fork bomb?
by Timothy Martin 07 Apr '07

07 Apr '07

I'm running dovecot on my FreeBSD 6.0 VPS (just upgraded from FBSD 4.x) and today my server completely ran out of resources and the logs for all my services had errors like this one from dovecot: Apr 6 19:32:22 design1st dovecot: fork() failed: Resource temporarily unavailable eventually it got worse: Apr 6 21:19:34 design1st dovecot: fork() failed: Resource temporarily unavailable Apr 6 21:19:34 design1st dovecot: Temporary failure in creating login processes, slowing down for now Apr 6 21:19:34 design1st dovecot: Created login processes successfully, unstalling Apr 6 21:19:35 design1st dovecot: fork() failed: Resource temporarily unavailable Apr 6 21:19:35 design1st dovecot: Temporary failure in creating login processes, slowing down for now Apr 6 21:20:36 design1st dovecot: fork() failed: Resource temporarily unavailable Apr 6 21:21:36 design1st dovecot: fork() failed: Resource temporarily unavailable Eventually the entire server became unresponsive. Normally I wouldn't even think of blaming dovecot, but the hosting tech support said that when the checked out "top" there were crazy amounts of imap processes (maybe they just aren't used to dovecot's methods of dealing with logins etc) but they blamed "my imap server". Any way I can find out if it's really dovecot that's causing this? I recognize it might not be a dovecot issue, but it's the only hint i've got right now. .tim

[Dovecot] zlib plugin
by guenther 07 Apr '07

07 Apr '07

Good evening, folks, Well, here at least. ;) I recently found out by accident about support for gzip compressed mbox files. While this is great for archives to keep wasting of space down to a minimum, unfortunately it is read only -- no support for rw access. Is implementing write access by any chance planned for future releases? Now for the spoiler. :) I mentioned, I found out about this feature "by accident", reading the NEWS for RC29. Talking to some guys on IRC I realized I am not the only one who found out about this by the release announcement. However, no one (around) was able to tell me how to use it, though interested too. I couldn't find any info in the docs, and google wasn't helpful either. But another careful look at the security announcement (especially the few words about it being a plugin not commonly used) got me going. So I figured, I'd mention it here -- I'm sure others have been wondering about this themself. And maybe google will pick up this post eventually. Of course, just sticking a gzipped mbox file inside your mail dir doesn't work... Inside the protocol imap section of the configuration, you need to enable the zlib plugin (and maybe set mail_plugin_dir, though the build time default should do). Basically, that's it -- once this is done, the naive first attempt magically works. ;) mail_plugins = zlib Of course, restart dovecot. Also, the gzipped mbox file needs to have a .gz suffix. This works for mbox files gzipped in one fell swoop just as well as incrementally concatenated single gzipped mails, as served by some mailing list servers as archives. Keep in mind though, that these archives are read only. With one notable exception: Read/Unread status is being updated and saved, as it will be stored in the index files in this case. This probably holds true for flags too, though I didn't test it. guenther -- char *t="\10pse\0r\0dtu\0.@ghno\x4e\xc8\x79\xf4\xab\x51\x8a\x10\xf4\xf4\xc4"; main(){ char h,m=h=*t++,*x=t+2*h,c,i,l=*x,s=0; for (i=0;i<l;i++){ i%8? c<<=1: (c=*++x); c&128 && (s+=h); if (!(h>>=1)||!t[s+h]){ putchar(t[s]);h=m;s=0; }}}

[Dovecot] Multiple delivery with LDA+sieve
by Vincent Bernat 07 Apr '07

07 Apr '07

Hi ! I am still a bit annoyed with the way that Sieve plugin handles multiple delivery into the same folder. For reference : http://www.dovecot.org/list/dovecot/2007-January/019029.html Summary : When a same message (same message-id) is to be delivered twice into the same mailbox, it is delivered twice while I think that the second one should be discarded. Here are a few test cases : - you subscribe to a few mailing lists on topic "X" and deliver all mails from those mailing lists in the same folder. You get twice the mails that are crossposted. - you subscribe to one mailing list and read it regulary so you don't care of receiving messages from this mailing list (you are in Cc when someone answers) in your INBOX. You match on To or Cc to put everything in the same folder. You get messages twice when you are put personally in Cc. - you place a forward from one account to two of your accounts (one is keeping backup, the other don't but delivers faster). You receive all messages twice. With procmail, I handle those (real) cases with formail. I can't with Sieve. I don't see any interest in receiving the same message twice into the same mailbox. Is it possible to maintain a list of recent message-id and mailbox couples to avoid to deliver again a message to the same mailbox ? -- Terminate input by end-of-file or marker, not by count. - The Elements of Programming Style (Kernighan & Plauger)

[Dovecot] mbox sync/lock issue, rc28 and later
by Jeff A. Earickson 06 Apr '07

06 Apr '07

Help! I just noticed this error this morning, we have been getting a lot of these in rc28 and rc29, not in rc27 or before: Apr 6 07:22:52 karst dovecot: [ID 107833 mail.error] IMAP(jaearick): mbox file /var/mail/j/jaearick was modified while we were syncing, check your locking settings Pine coughed up an internal error, no core dump, and dovecot basically doubled the size of my mailbox by duplicating all of my messages again. What changed with file locking between rc27 and rc28 to cause this? How to fix? My setup: dovecot server is Solaris 10, with ZFS for home directories (where index files go). The mail server is also Solaris 10, /var/mail NFS mounted to the dovecot server (NFSv4, yes lockd is running). The /var/mail filesystem on the mail server is also ZFS.

[Dovecot] [ rc28 ] dict{} seems to be ignored
by Emiliano Gabrielli (aka AlberT) 06 Apr '07

06 Apr '07

Hi all, I'm new to the list, so ... hello everybody :-) Let's go to the point... I'm implementing quota over imap support in my mail server, so since a number of days I'm tring to upgrade to the new 1.x version (debian sarge) ... After having a number of troubles using the debian backport packege I am now using the -rc28 package that I have built by myself... I installed libmysqlclient14 and compiled dovecot with the following configure options: ./configure --with-ssl=openssl \ --with-mysql \ --disable-ipv6 \ --with-cyrus-sasl2 \ --with-gssapi \ --with-deliver \ --host=$(DEB_HOST_GNU_TYPE) \ --build=$(DEB_BUILD_GNU_TYPE) \ --prefix=/usr \ --sysconfdir=/etc/dovecot \ --libexecdir=\$${prefix}/lib \ --localstatedir=/var \ --mandir=\$${prefix}/share/man \ --infodir=\$${prefix}/share/info \ --with-moduledir=\$${prefix}/lib/dovecot/modules as taken from the sarge-backports debian package and after having removed pgsql, ldap and ipv6 support, as I don't need them... The imap over quota seem to work perfectly, since I can see quota info in IMAP clients (and via telnet) the only thing I can't make work is the dict: storage for quota info!! It seems the dict{ .. } section in the dovecot.conf file is *totally* ignored: dict { quotadict = mysq:/etc/dovecot/dovecot-dict-quota.conf } As you can see I have a typo in the driver name, but no error nor error message is given ... I followed the wiki instruction about Quota/Dict and I have created the necessary table ... that is not filled of course .. Anybody can tell me if may be a compilation problem, a configuration one or a bug in the current dovecot release ??

[Dovecot] Problems using GFS2 and clustered dovecot
by David Craigon 06 Apr '07

06 Apr '07

I am trying to use dovecot. I've got a GFS2 shared volume on two servers with dovecot running on both. On one server at a time, it works. The test I am trying is to attach two mail programs (MUA) via IMAPS (Thunderbird and Evolution as it happens). I've attached one mail program to each IMAPS server. I am trying to move emails around in one program (from folder to folder), and then checking it on the other program. I'm testing in effect how it would work if my users log on twice and end up on different servers. I seem to suffer from never ending index file corruption: Apr 4 16:55:49 mailstore-b dovecot: IMAP(david(a)everybody-loves.craigon.co.uk): Corrupted transaction log file /mnt/mailstore/e/everybody-loves.craigon.co.uk/d/david/.fish/dovecot.ind ex.log: end_offset (284) > current sync_offset (104) Apr 4 16:55:49 mailstore-b dovecot: IMAP(david(a)everybody-loves.craigon.co.uk): broken sync positions in index file /mnt/mailstore/e/everybody-loves.craigon.co.uk/d/david/.fish/dovecot.ind ex Apr 4 16:55:49 mailstore-b dovecot: IMAP(david(a)everybody-loves.craigon.co.uk): fscking index file /mnt/mailstore/e/everybody-loves.craigon.co.uk/d/david/.fish/dovecot.ind ex Apr 4 16:55:49 mailstore-b dovecot: IMAP(david(a)everybody-loves.craigon.co.uk): Fixed index file /mnt/mailstore/e/everybody-loves.craigon.co.uk/d/david/.fish/dovecot.ind ex: log file sync pos 1,284 -> 1, 104 Apr 4 16:55:50 mailstore-b dovecot: IMAP(david(a)everybody-loves.craigon.co.uk): Unexpected transaction log desync with index /mnt/mailstore/e/everybody-loves.craigon.co.uk/d/david/.fish/dovecot.ind ex Apr 4 16:56:18 mailstore-b dovecot: IMAP(david(a)everybody-loves.craigon.co.uk): Transaction log file /mnt/mailstore/e/everybody-loves.craigon.co.uk/d/david/.fish/dovecot.ind ex.log: marked corrupted This happens pretty quickly. I can also get message duplication- if I move a message from one server to another, I can get a message in the original folder and the destination folder. I am using RC28. I have tried using fcntl locking and dotlocking with equal lack of success. Can anyone offer any advice?

[Dovecot] managesieve proxy
by Marshal Newrock 06 Apr '07

06 Apr '07

We have dovecot on a pop/imap server working as a proxy to dovecot on the backend storage servers. This is working fine, but the difficulty is that if I use, for example, avelsieve in squirrelmail, it doesn't know where to connect. I imagine the same problem would exist with sieve-capable mail clients such as KMail, especially since the outside world isn't allowed to connect directly to the storage servers. Does anyone know of a way to proxy managesieve? -- Marshal Newrock Ideal Solution, LLC - http://www.idealso.com

[Dovecot] GSS/Kerb5, Solaris 10, how to build?
by Jeff A. Earickson 06 Apr '07

06 Apr '07

Gang, I've been trying to build rc29 under Solaris 10 using either "--with-gssapi" or Kerberos 5 ticket usage. I'm trying to figure out how to set up fetchmail on another S10 box to do IMAP fetches from dovecot without having to enter a password. No matter what configure option I try, I get Building with GSSAPI support ........ : no at the end of the configure. I searched the list archives and I see some discussion from Dan Price about Solaris 11 builds. Is gssapi supposed to work with Solaris 10? Advice please? My dovecot server is a Kerberos 5 client of Active Directory, with PAM configured to do TGT exchanges. I can login to the system with my AD password, ssh to other Kerb clients without having to type in passwords -- Kerberos works at the OS level. Jeff Earickson Colby College

[Dovecot] changing fs separator for maildir (suggestions?)
by Justin McAleer 05 Apr '07

05 Apr '07

Since we're migrating from an existing system that allows periods in folder names, I believe we must continue to allow them. So, I am deciding what to use as the separator instead. Right now, I'm leaning towards the backtick (`), since I don't think I have ever used it unless I was trying to execute an external command in some code. So, can anybody think of reasons not to use it, or have a better idea?

Re: [Dovecot] Problems using GFS2 and clustered dovecot
by David Craigon 05 Apr '07

05 Apr '07

Well, I'm not paying for it. And I've managed to fix the comedy stability I've come across so far, but you're right- I haven't really loaded the system up yet. My rationale is that I want a filesystem I can share between several servers, reducing the points of failure as far as I can down. We've got a large iSCSI SAN we've already bought for other projects, and I'd like to use that for our storage. So using NFS, I'd have to have another server in front of my SAN that act as an NFS server (presuambly as a single point of failuire), and the mail servers as NFS clients. I'd rather have the servers talk to the SAN directly. Besides, NFS never really works for me, but I'm sure I could overcome that. Anyway, I don't think it's a GFS problem so far.

Re: [Dovecot] compiling dovecot on aix gcc 3.3.2
by Ralf Becker 05 Apr '07

05 Apr '07

Hello funkypunky drunky, on AIX dovecot plugins (which are shared objects = .so) are a little bit problematic. It is not enough to activate run time linking by using -brtl and make the main program (dovecot) to be able to use shared objects. When a share object does function calls back into the main program, all these functions (=symbols) in dovecot have to be explicitly exported. Otherwise you see "signal 11" or so. Because this is very fiddly, there is a linker flag -bexpall to export all symbols of the main program (dovecot)... but this does seemingly not work with symbols defined in static libraries (.a). While dovecot build creates static libraries to keep the linker command line small, but does *not* generate export files (.exp) containing the libraries globals symbols, the compile time linker does not known anything about them. I think, if dovecot build would use libtool to create the libraries, libtool would export the libraries symbols to fix this. And this is, what my script does. It looks on the compiler command line for library file (.a) and exports all global symbols to an .exp file. The paths of these .exp files are appended to the original compiler command line and so -bexpall knows about the globale symbols defined in the libraries and is able to export them. I don't know if this information is useful for you, because you're using gcc. But if you are using AIX ld (instead of gnu ld) you have to deal with this problem, I think.

[Dovecot] 1.0.rc29 released
by Timo Sirainen 05 Apr '07

05 Apr '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

[Dovecot] *****SPAM***** The folder 'Inbox' cannot contain items. Namespace problems
by Francisco Reyes 05 Apr '07

05 Apr '07

Several attempts to support both Mac and PCs keep failing. In my latest attempt I used the following settings: #courier-imap compatibility/Thunderbird namespace private { separator = . prefix = INBOX. inbox = yes } For MAC OS Mail.app namespace private { separator = / prefix = INBOX/ inbox = no hidden= yes } This last attempt was based on the suggestion of Timo Sirainen, on the Mac settings. The PC settings were the defaults I got from the sample config and have always worked for PC clients. The new setup with namespace private worked for Mac clients, but got the following error for a number of users in both Outlook and thunderbird. Unable to display the folder. The folder 'Inbox' cannot contain items. This is most likely a limitation of your IMAP server. In order to create a folder that can contain items, be sure to append / to its name as you create it. I see this is an old issue. http://groups.google.com/group/microsoft.public.outlook/browse_thread/thread /5f990142171fb792/62adb6c069946e40?lnk=st&q=%22cannot+contain+items%22+dovec ot&rnum=1#62adb6c069946e40 One interesting point we discovered was that if we set an IMAP account in Outlook the very first time we logged in, it worked. If we closed the client, all subsequent times the "folder Inbox cannont contain items" error would come up. doing a TCPdump showed us that the difference was that the first time that Outlook connects it issued a "Select" command, but all other times it did not. Someone suggested to take out prefix = INBOX. Would that help? I don't want to cause problems for the vast majority of our PC users while trying to fix the Mac clients. Even though Mac users are a minority of our users, it is extremely problematic for us not to be able to support them because many domains may have a handfull of such clients.. so we basically will not be able to host a large number of domains in dovecot machines, just because of a handfull of Mac clients. Currently using Dovecot r27, but have been having this same problem since r15.

[Dovecot] Login lockups
by Daniel L. Miller 04 Apr '07

04 Apr '07

When dovecot works - it works great, and I thank you. But it seems like every time I setup a new server, it's a challenge getting the IMAP logins to work reliably. The changelog's top comment is stamped 2007-01-05, 18:48 if that helps nail down the version (I'm using a Debian/Ubuntu package). Both non-SSL and SSL logins have the problem. This time around I'm using LDAP authentication - and once I figured out how it worked beautifully. The problem is from time to time - with no particular consistency - I lose the ability to log in. A "telnet localhost 143" on the server works with a Dovecot response, then followed with a "01 LOGIN <user> <password>" results in a long delay, then a timeout, with no log files affected. What can I provide to try to trace this? protocols = imap imaps disable_plaintext_auth = no login_process_per_connection = yes -- Daniel

[Dovecot] logfile consistency
by David Lee 04 Apr '07

04 Apr '07

We do some routine logfile (syslog) gathering and analysis. I've been looking at extending this to parse the syslog output of dovecot. Hmmm... Ignoring the leading 'date hostname' prefix, some sample lines are: dovecot: imap-login: Login: user=<uuuuuu>, method=PLAIN, rip=dd.dd.dd.dd, lip=dd.dd.dd.dd dovecot: IMAP(uuuuuu): Disconnected: Logged out dovecot: IMAP(uuuuuu): Disconnected in IDLE dovecot: imap-login: Aborted login: rip=dd.dd.dd.dd, lip=dd.dd.dd.dd dovecot: pop3-login: Login: user=<uuuuuu>, method=PLAIN, rip=dd.dd.dd.dd1, lip=dd.dd.dd.dd dovecot: POP3(uuuuuu): Disconnected: Logged out top=0/0, retr=0/0, del=0/8, size=194970 dovecot: pop3-login: Aborted login: rip=dd.dd.dd.dd, lip=dd.dd.dd.dd deliver(uuuuuu): msgid=<014089712.74355909944644(a)thhebat.net>: saved mail to INBOX I've obfuscated some of the local detail: uuuuuuu represents a username/identifier; dd.dd.dd.dd represents an IP address. Would it be possible, please, to consider improving the consistency of the logging information? For instance: 1. All lines, including the "deliver", to begin "dovecot:"; 2. The "IMAP(uuuu): Disconnected" to become "imap: disconnected user=<uuuu>"; Overall this would make it more consistently amenable to perl-like pattern processing, at least with a reasonably hierarchical structure to the messages. Perhaps something like: dovecot: subprogram: event, key1=value1, key2=value2 ... where: "subprogram" is "{imap,pop,deliver,...}"; "event" is "{login,disconnected, ...}; and one of the "key=value" will usually be "user=<uuuu>". That would really make post-processing of logging information (whether offline, or 'live' via piped syslog) considerably easier. Thanks. -- : David Lee I.T.

[Dovecot] How to integrate dspam and dovecot
by Manilal K M 03 Apr '07

03 Apr '07

Hello all, I am currently setting up a new mail server with Qmail, OpenLDAP and Dovecot in CentOS-4.4. Qmail version is 1.03, OpenLDAP is 2.3 and Dovecot version is dovecot-1.0-3_50.rc27(RPM). I have successfully installed and tested it. But I have two issues with the current setup: #1. I am using dovecot LDA and configured the OpenLDAP such that the mail be delivered to the virtual users through a script. This script is saved in /var/qmail/bin/deliver.sh and the contents is as follows: /usr/bin/dspam --stdout --mode=tum --deliver=innocent,spam --feature=chained,noise --user global |/var/qmail/bin/preline -f /usr/libexec/dovecot/deliver -d $RECIPIENT || exit 77 This script name is mentioned in each user's deliveryProgramPath in the LDAP. I am not sure whether this is the best approach of using dovecot as MDA. I tried to include the following contents in /var/qmail/control/defaultdelivery : |/var/qmail/bin/preline -f /usr/libexec/dovecot/deliver -d $RECIPIENT But it seems that this is not working as desired. Please comment, if I have gone wrong anywhere. #2: I wish to use dspam to filter out the spam messages, but I am unsure whether the dspam plugin mentioned in http://johannes.sipsolutions.net/Projects/dovecot-dspam-integration is already in the dspam version I am using. If it's available please give details to configure it. Kindly share ideas. regards Manilal. -- Better to light one candle than to curse the darkness.

[Dovecot] No CA names sent in TLS handshake
by Johnny Chadda 03 Apr '07

03 Apr '07

Hello, I'm setting up Dovecot with client certificates and everything is working fine as long as the client only has one certificate in his store. If he has more than one, the wrong one might be sent to the server. The root of the problem is that Dovecot does not send out a list of valid CA names in the TLS handshake. If I connect using openssl s_client I get: "No client certificate CA names sent" I am using Dovecot 1.0 RC15 from backports.org. Is there a solution to this problem? Regards, Johnny

[Dovecot] *****SPAM***** Upgrading from rc27 to rc29?
by Francisco Reyes 03 Apr '07

03 Apr '07

After sending a messasge about a problem (The folder 'Inbox' cannot contain items. Namespace problems) I found what seems to be a fix in the release for rc29. Besides any potential configuration files, do I need to delete the old index files? Any of the dovecot files? Based on the release notes for rc29 it seems the following will fix the problem we are experiencing: IMAP: LIST "" "" didn't return anything if there didn't exist a namespace with empty prefix. This broke some clients.

[Dovecot] [PATCH] to fix 2 pam issues
by Phil Oleson 03 Apr '07

03 Apr '07

Timo, I finally made the time to backport a pam fix I created for proftpd over to dovecot, that allows FreeBSD's pam_group to work as expected. (the bug was escalated to me internally hehe.. ). I also noticed an issue while testing that will be confusing to users. If the docs stay as is, or the other half of this patch is applied, then when the dovecot.conf contains: passdb pam { args = * } the imap files within etc/pam.d right now have to be named 'IMAP' and 'POP3' rather than the expected 'imap' and 'pop3'.

[Dovecot] vpopmail "last auth" question
by B. Cook 03 Apr '07

Hello, I run the domain for the school here with qmail and vpopmail on FreeBSD with dovecot from the ports. I'm running dovecot 1.0.r26 and everything is working great.

[Dovecot] Suggestion: mod_auth_dovecot
by David Anderson 03 Apr '07

03 Apr '07

Hello, I have a suggestion which might be a small and very useful project for a C coder (I'm not one!). As Dovecot makes its authentication interface available to other programs, I think that an Apache module to use it would be very useful. Currently I share an passwd-db file between Dovecot and Apache. However with Apache that means I have to give Apache read access. That means that websites with PHP could read that password file if they liked. If Apache could talk to the Dovecot authentication process instead, that would be a lot better. I'm sure there are lots of situations in which this would be useful - Dovecot's authentication settings are so flexible that it would be very handy to be able to use them more widely. If anyone produces one, I pledge to produce an RPM package and submit it to Fedora as my contribution. I would do it myself if I knew C... David

[Dovecot] prefetch + static + deliver
by Tom Bombadil 02 Apr '07

02 Apr '07

Hi all... The prefetch entry in the wiki says: "If you're using Dovecot's local delivery agent, you'll still need a valid userdb which it can use to locate the users. You can do this by adding a normal sql/ldap userdb after userdb prefetch." (http://wiki.dovecot.org/UserDatabase/Prefetch) My question is: Does it need to be a SQL/LDAP userdb? How about static or passwd? Thanks in advance :)

[Dovecot] testing LDAP connections
by Hugo Monteiro 02 Apr '07

02 Apr '07

Hello all, I haven't looked into the source code, but i suspect that LDAP connections, once established, are not tested properly. My scenario is the followind: Dovecot server <--------> firewall <---------> LDAP backend What happens is that the firewall has a security feature which basically make de firewall box "forget" about connections that are idle for more than X period of time. That particular setting is 30 minutes right now. When that happens, neither the LDAP backend or the Dovecot server get any type of notification, and for all they care the connection is alive and well. This is a very common implementation in firewalls nowadays. So my question is, is there any way to make dovecot re-open a new connection if there is a timeout while trying to use a connection already opened? I believe that this could be of great benefit for those who don't have their servers on the same physical network.

[Dovecot] Using Dovecot LDA with Sendmail
by Scott Peron 02 Apr '07

02 Apr '07

Hi all, After looking at the LDA/Sendmail page in the dovecot wiki, I wanted to contribute another method to easily configure Sendmail to use deliver. Instead of adding a new mailer definition, as already suggested, one can simply use the following line in their sendmail.mc file instead: FEATURE(`local_procmail', `/usr/libexec/dovecot/deliver', `deliver -d $u', `SPhnu9')dnl And further on, still use: MAILER(procmail)dnl The location of deliver will of course vary for each OS and distro, etc, but this redefines the "procmail" mailer in the resulting sendmail.cf to use deliver instead, with the correct flags. For most setups, I believe this is the simplest configuration path.

[Dovecot] Unexpected behaviour when deleteing a big mailbox
by Steffen Kaiser 02 Apr '07

02 Apr '07

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, my last tests left me with a mailbox with > 80'000 messages in Maildir. Dovecot served them fine. No problem. I usually use IMAP's "Mark messages a deleted" function and expunge later. Because the "Move to Trash" is default in many MUAs, I decided to try it on this mailbox. I do think that it is hard to detect and prevent such problem, but could it be implemented that when the client connection times out, the COPY process is terminated and rolled back? I mean, as long as the messages are copied/linked to */tmp nothing is done, yet, hence, a simple cleanup of */tmp would result in a rollback. Due to the timeout, the EXPUNGE wasn't issued so far and the source mailbox is unchanged. Or, is it possible to prevent two COPYs of an overlapping message range into the same destination folder simultaneously? Or, can I prevent to COPY such a huge range of messages at once? I know 80'000 messages are much, but I have users with an INBOX of at least 40'000, eventually moving all files into an archive mailbox. I'm also surprised to find that I didn't get two full copies of the source mailbox. ============== Start situation: 4.8G .box1 (I didn't recorded the individual subdirs, unfortunately.) # find .box1 -type f | wc -l 84273 Newly created .Trash. === I started Thunderbird, let sync the mailbox, selected them all, and pressed "Delete". Some time later: Connection timed out. I, wondered, and hit "Delete" a second time. Again, connection timed out. === I was surprised, however, to see that the Dovecot log with still active telling me that mails are copied to Trash. I ended up with two processes copying all messages to .Trash/tmp on the server. The process I traced a bit later linked any file after the other. What I wondered right from the beginning was, that du -hs .??* displayed about 3.5GB in .Trash, but still 4.8GB in .box1. So, why are there 3.5GB additional files in .Trash, when I configured Dovecot to use hardlinks? The end situation is that .box1 contains all messages still, but any Unseen messages are moved to .box1/cur, and .Trash contains: 7.4G .Trash/cur 791M .Trash/new 76K .Trash/tmp # find .Trash/ -type f | wc -l 121713 The size nearly doubled. # du -hs .box1 ; du -sh .Trash/ 4.8G .box1 8.2G .Trash/ ==== Last lines in Dovecot log: dovecot: Mar 21 11:46:15 Info: IMAP(dvtest) [11535]: copy -> Trash: uid=83964, msgid=<xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx(a)xx-xxxx-xxxxx-xxxx.xx>, box=box1 dovecot: Mar 21 11:46:15 Info: IMAP(dvtest) [11535]: copy -> Trash: uid=83965, msgid=<xxxxxxxx.xxxxxxx(a)xx-xxxx-xxxxx-xxxx.xx>, box=box1 dovecot: Mar 21 11:46:29 Info: IMAP(dvtest) [11535]: Disconnected: Mailbox is in inconsistent state, please relogin.

[Dovecot] imaptest10 and stalled messages
by Mike Brudenell 01 Apr '07

Greetings - I've now got as far as playing with the imaptest10 test utility to see if I can stress-test our development server. imaptest10 is built against dovecot-1.0rc28 It may just be that I'm excessively heavy handed, but when I let imaptest10 rip with the command... ./imaptest10 user=test%03d host=testserver.imap.york.ac.uk clients=50 mbox=./dovecot.mbox msgs=1000 secs=30 logout=10 ...after 15 seconds or so I started getting output along the lines of: Logi List Stat Sele Fetc Fet2 Stor Dele Expu Appe Logo 100% 50% 50% 100% 100% 100% 50% 100% 100% 100% 10% 30% 5% 2 0 1 1 1 0 0 0 0 0 0 50/ 50 2 0 0 1 1 0 0 0 0 0 0 50/ 50 0 0 2 2 0 1 1 1 1 1 0 50/ 50 2 0 2 2 0 1 1 1 1 1 2 50/ 50 0 0 1 1 0 0 0 0 0 0 0 50/ 50 - 16. stalled for 16 secs in LOGIN - 17. stalled for 16 secs in LOGIN - 18. stalled for 16 secs in LOGIN 2 1 1 2 1 0 0 0 0 0 0 50/ 50 - 17. stalled for 17 secs in LOGIN - 18. stalled for 17 secs in LOGIN - 22. stalled for 16 secs in LOGIN - 23. stalled for 16 secs in LOGIN - 24. stalled for 16 secs in LOGIN 1 0 1 1 0 0 0 0 0 0 0 50/ 50 - 17. stalled for 18 secs in LOGIN - 18. stalled for 18 secs in LOGIN - 22. stalled for 17 secs in LOGIN - 23. stalled for 17 secs in LOGIN - 24. stalled for 17 secs in LOGIN - 28. stalled for 16 secs in LOGIN - 29. stalled for 16 secs in LOGIN - 30. stalled for 16 secs in LOGIN - 31. stalled for 16 secs in LOGIN - 32. stalled for 16 secs in LOGIN The "stalled" log lines continue until the test completes. I'm assuming it's just that I'm pushing our hardware beyond its reasonable limits: it is only an oldish development box... Sun v120 with 1 650MHz SPARC processor and 1Gbyte RAM Dovecot is using shadow password file authentication. The mail folders are in Maildirs, NFS-mounted from a NetApp filer, and each account's INBOX has around 1000 messages in it. Control and Index files are on local disk. By the end of the 30 second test run load average has climbed to around 11 I don't know how "active" the imaptest10 utility is when it's running, but do you think I should be concerned by the "stalled" messages? That is, do you think I have something configured amiss? Or is it likely just to be I'm expecting too much of our hardware? (The real system will have beefier Suns with Opteron-based CPUs, more memory, etc) With thanks, Mike B-) PS. I forgot to say: despite all this activity there's not a single error logged by Dovecot in the (admittedly short at this stage) test runs. -- The Computing Service, University of York, Heslington, York Yo10 5DD, UK Tel:+44-1904-433811 FAX:+44-1904-433740 * Unsolicited commercial e-mail is NOT welcome at this e-mail address. *

[Dovecot] locking question
by Stewart Dean 01 Apr '07

01 Apr '07

There are three applications that have their mitts on files on my mail server, which is running AIXV5.3 and UWIMAP and mbox format. The mail folders and INBOXES are native to that machine, but also are NFS exported to a login server and a mailing list server. All three machines are running the lockd daemon. Everybody wants to lock differently 1) procmail (delivering for sendmail), which seems to want to use dotlocking, fcntl and lockf locking; for whatever reasons, the compile time tests seem to disallow flock. 2) UWIMAP which according to wiki.dovecot.org/Migration/UW uses: mbox_read_locks = flock mbox_write_locks = dotlock flock 3) I want to run dovecot in the same environment as I switch over, for which the locking strategy is supposed to be (according to http://wiki.dovecot.org/MboxLocking) mbox_read_locks = fcntl mbox_write_locks = dotlock fcntl Since that same page in the wiki says. "*It's important that all software that's reading or writing to mboxes use the same locking settings.",* I had recompiled procmail so it only usedotlocking and fcntl (thus removing lockf in addition to the disallowed flock)...but now I bumped into the Migration/UW page and there looks to be a conflict. I want to be able to run dovecot (for testing) and UWIMAP (for all users/production) at the same time (but never at the same time with the same mailbox), but UWIMAP is doc'ed to use flock and Dovecot doesn't It's conceivable that the different locking strategies of UWIMAP and Dovecot don't matter because they would never be going after the same mail files (right?) but there is procmail, which has to interact with both. It appears to not use flock OK, even though the docs say it should since UWIMAP expects it, and I've disabled lockf as well. But will there be a conflict with procmail and dovecot's use of fcntl, which UWIMAP doesn't use?

[Dovecot] 1.0rc29: Corrupted index cache file
by Jeff Rice 01 Apr '07

01 Apr '07

Hi, I have recently migrated from Courier to Dovecot, and I noticed a problem in one of my spam scripts. Here's the setup: Spam that needs to be retrained by the filter is placed in a maildir from the IMAP client. A cron job scans that maildir and if it finds a message, feeds it to the spam filter and removes it from the training maildir. Depending on whether or not the message was a spam or ham, it is either deleted or delivered to Inbox. It appears I am getting an error when the script deletes a mail message. I haven't checked if this message only occurs when a client is connected -- it's possible. Log excerpt: Mar 31 18:34:57 finity dovecot: IMAP(XXXXXXX(a)finity.org): Maildir /home/vmail/XXXXXXX(a)finity.org/.Spam.Unsure sync: UID inserted in the middle of mailbox (8 > 3, file = msg.FHoB:2,) Mar 31 18:34:57 finity dovecot: IMAP(XXXXXXX(a)finity.org): Disconnected: Mailbox is in inconsistent state, please relogin.

[Dovecot] convert plugin failing
by Adrian Bridgett 31 Mar '07

31 Mar '07

I'm struggling to get the convert plugin working using the Debian etch packages. When starting dovecot it was trying to create files in /.temp.hostname... convert-plugin.c looks like it has a couple of typos in it - it checks "mail" three times for NULL rather than mail, user, home. I changed this but it's getting called when these three items are set to: "maildir:/HOME_DIRECTORY_USED_BUT_NOT_GIVEN_BY_USERDB/Maildir" "dump-capability" "" I must be missing something - shouldn't the mailboxes only be converted when a user logs in? Should the conversion be skipped for the dump-capability user (whatever that is!) Thanks, Adrian -- Adrian Bridgett - adrian(a)smop.co.uk GPG key available on public key servers

Hi all, Merging the two large recent threads, my recommendation is as follows: * The Release Candidates for 1.0 should be bug fixes only. * Each new Feature, or a Feature Set, goes in a separate branch. * That branch is tested by those who need/want that feature. * When testing is completed, the branch is merged into the main trunk. This way, we will have fairly well tested features/feature sets in the main trunk which people can fairly safe download and test and deploy, if their own tests succeeds. When the feature code is merged into the main trunk, the minor version is incremented by one (1.0.x --> 1.1.0). Bug fixes increment the revision (1.1.0 --> 1.1.1). Easy to follow, easy to package for package maintainers. Also, it's easy to write Readme's and other documentation on what's changed. (And for those who think that odd versions are for development (unstable), well, they will just wait until sufficient features have been added before they think it is stable... ) Timo's new features he sees for future versions, plan them for a 2.0 or a 1.1 or whatever version number, just don't call it 1.0.2rc1 :-) Another suggestion, is to create a Bugzilla (or similar) site for dovecot. That gives us all a chance to track changes and bug fixes. /Peter, building rc29 as I write this

[Dovecot] rc28 : can't set quotas with userdb + passwd file
by David Anderson 30 Mar '07

30 Mar '07

I'm using dovecot 1.0 rc28 - great software! I have a virtual hosting setup, with passdb and userdb both using a passwd file. I cannot get per-user quotas put in the relevant field of the userdb to work. They appear to be completely ignored; only the setting from /etc/dovecot.conf is applied. Can anyone confirm that this is working for them? If it is, can you post the relevant bits of your configuration, please? Many thanks. Kind regards, David

[Dovecot] Freebsd 4 error DSN stat=Service Unavailable after dovecot install

Hello everyone, I am getting an error message on FreeBSD 4 after I install dovecot. To start off, I create two regular users, testuser and testuser1. I send each user emails then I install dovecot. After installing dovecot I set up the users in Maildir format then proceed to send them emails and here is what shows up in the maillogs: Email to testuser3 - Mar 29 22:34:52 myserver sendmail[4379]: l2TMYqwj004379: from=root, size=54, class=0, nrcpts=1, msgid=<200703292234.l2TMYqwj004379(a)myserver.vwh.net>, relay=r oot@localhost Mar 29 22:34:52 myserver sm-mta[4380]: l2TMYqMi004380: from=<root(a)myserver.vwh.net>, size=342, class=0, nrcpts=1, msgid=<200703292234.l2TMYqwj004379@myserver .vwh.net>, proto=ESMTP, daemon=MTA-v4, relay=localhost [127.0.0.1] Mar 29 22:34:52 myserver sendmail[4379]: l2TMYqwj004379: to=testuser3(a)myserver.vwh.net, ctladdr=root (0/0), delay=00:00:00, xdelay=00:00:00, mailer=relay, pr i=30054, relay=localhost..

[Dovecot] Security hole #3: zlib plugin allows opening any gziped mboxes
by Timo Sirainen 30 Mar '07

30 Mar '07

zlib plugin allows opening gzipped mboxes as read-only mailboxes. However when using it, the mailbox name checks are bypassed so it's possible to open for example "../otheruser/somefile.gz". Only valid gzipped mbox files can be opened, and only if their name ends with ".gz". You can fix this by upgrading to v1.0.rc29 (available soon) or with this patch: http://dovecot.org/list/dovecot-cvs/2007-March/008488.html I don't think this matters much though. zlib plugin is rarely used, and those who do use it are probably using Dovecot with systems users (per-user UIDs), so the imap process wouldn't have access to other users' mbox files anyway. I found this problem when I was cleaning up the code in CVS HEAD.

[Dovecot] uiddir mailbox format with benchmarks
by Timo Sirainen 30 Mar '07

30 Mar '07

I cleaned up the lib-storage code a bit so that it's easier to write support for new mailbox formats. It could still use a bit of cleaning up. Anyway, I thought I'd try how easy it would be to implement Cyrus-like mail store which would consist of only Dovecot's index files and "<uid>." message files. Flags and everything else is kept only in Dovecot's index files (so it might not be the best idea to use it in production just yet). Several hours later I ended up having it working. The code contains: ~/cvs/m/dovecot-head/src/lib-storage/index/uiddir% wc *[ch] 144 329 3552 uiddir-mail.c 240 565 6206 uiddir-save.c 532 1367 13628 uiddir-storage.c 55 126 1712 uiddir-storage.h 169 404 4057 uiddir-sync.c 21 48 573 uiddir-sync.h 103 258 2762 uiddir-transaction.c 1264 3097 32490 total uiddir-storage.c is still a bit too bloaty with lots of copy&pasted code. The same with maildir and mbox: maildir: 6022 18232 165605 total mbox: 7859 23283 213686 total Benchmarks show that with small mailboxes it's a lot faster than maildir, and with larger mailboxes it's a bit faster. I also tested it against Cyrus. I found out that fetching ENVELOPE vs. specific headers gives quite a huge performance difference. Cyrus is optimized for ENVELOPE while Dovecot is optimized for specific headers. With larger mailboxes + ENVELOPE Cyrus is faster than Dovecot, while with specific headers Dovecot is always faster. Maybe I'll some day make Dovecot optimize for ENVELOPE also if it sees that client only wants to use it. BTW. Does anyone have better naming ideas than "uiddir"? I'll commit it to CVS HEAD once I'm sure about the name. :) u: Dovecot CVS HEAD + uiddir m: Dovecot CVS HEAD + Maildir c: Cyrus IMAP 2.2.13 ./imaptest list=0 seed=1 secs=60 clients=10 Logi Stat Sele Fetc Fet2 Stor Dele Expu Appe Logo u: 23486 11822 23481 23476 33426 11659 8038 23472 11922 46952 m: 19367 9734 19367 19356 27453 9687 6287 19347 7983 38709 c: 5124 2553 5121 5105 7080 2559 1877 5104 3271 10228 ./imaptest list=0 dele=20 expu=20 seed=1 secs=60 msgs=10000 clients=10 Logi Stat Sele Fetc Fet2 Stor Dele Expu Appe Logo u: 5291 2704 5289 5278 7448 2706 1048 1061 5283 10563 m: 4162 2103 4162 4153 5977 2124 762 853 4153 8304 c: 4302 2157 4301 4289 6021 2072 806 879 4292 8584 ./imaptest list=0 dele=10 expu=10 seed=1 secs=60 msgs=100000 clients=10 Logi Stat Sele Fetc Fet2 Stor Dele Expu Appe Logo u: 3211 1637 3206 3195 4639 1537 287 302 3202 6402 m: 2957 1508 2955 2944 4173 1440 279 306 2948 5894 c: 3933 1929 3933 3920 5604 2020 380 379 3923 7846 ------ ./imaptest list=0 dele=10 expu=10 seed=1 secs=60 msgs=100000 clients=1 Logi Stat Sele Fetc Fet2 Stor Dele Expu Appe Logo u: 1529 745 1529 1528 2184 819 136 162 1528 3056 c: 1579 813 1579 1578 2257 811 171 148 1578 3156 ./imaptest list=0 dele=10 expu=10 seed=1 secs=60 msgs=100000 clients=50 Logi Stat Sele Fetc Fet2 Stor Dele Expu Appe Logo u: 3098 1552 3093 3085 4432 1520 293 334 3089 6173 c: 3664 1765 3659 3596 5106 1802 365 364 3614 7228 ====== FETCH BODY.PEEK[HEADER.FIELDS(from to cc subject)] instead of ENVELOPE: ./imaptest list=0 dele=20 expu=20 seed=1 secs=60 msgs=10000 clients=10 Logi Stat Sele Fetc Fet2 Stor Dele Expu Appe Logo u: 5777 2933 5777 5767 8215 2901 1133 1191 5767 11531 c: 3636 1794 3635 3623 5196 1843 682 722 3627 7254 ./imaptest list=0 dele=10 expu=10 seed=1 secs=60 msgs=100000 clients=10 Logi Stat Sele Fetc Fet2 Stor Dele Expu Appe Logo u: 3869 1959 3868 3861 5452 1943 364 394 3859 7717 c: 3191 1620 3189 3184 4501 1598 315 327 3181 6362 ./imaptest list=0 dele=10 expu=10 seed=1 secs=60 msgs=100000 clients=1 Logi Stat Sele Fetc Fet2 Stor Dele Expu Appe Logo u: 1912 966 1912 1910 2783 940 184 197 1911 3820 c: 1342 696 1342 1341 1888 682 109 126 1341 2682 ./imaptest list=0 dele=10 expu=10 seed=1 secs=60 msgs=100000 clients=50 Logi Stat Sele Fetc Fet2 Stor Dele Expu Appe Logo u: 4618 2320 4610 4604 6558 2266 452 455 4605 9205 c: 2960 1472 2956 2941 4134 1425 281 312 2910 5820

[Dovecot] sieve-body extension support for deliver LDA's sieve plugin
by Scott Peron 30 Mar '07

30 Mar '07

Hi Timo & Co, Is there any time frame for updating the deliver LDA's sieve plugin code to that from Cyrus IMAPd v2.3.x? I ask as I'm looking for the functionality of the sieve-body extension, as described here: http://www.ietf.org/internet-drafts/draft-ietf-sieve-body-06.txt This requirement has come up as we're upgrading from a Courier-IMAP/maildrop configuration that has some filtering based on message body content. As an aside, if that time frame is undefined or will be long, if I use maildrop instead as my LDA, will I loose the instant delivery notification via IMAP IDLE? Thanks very much, Scott -- Scott Peron, Webmaster, Infolytica Corp. webmaster(a)infolytica.com Tel: (514) 849-8752 x269 Fax: (514) 849-4239 http://www.infolytica.com Place du Parc, 300 Leo-Pariseau, Suite 2222, Montreal, QC, Canada, H2X 4B3

[Dovecot] Version numbering
by Timo Sirainen 30 Mar '07

30 Mar '07

After v1.0 is released, I can finally get back to sane version numbers. But any comments on which one is better: a) Postfix-style: "1.1.UNSTABLE.YYYYMMDD" -> 1.1.0 (stable) b) Odd-even numbering: 1.1.x (unstable) -> 1.2.0 (stable) With a) style the releases could be done by simply copying a nightly snapshot to releases/ directory and announcing the changes since the last release. I'm not sure if that's good or bad.

Have the RC's released new features as well as fixed bugs? I've been hesitant to upgrade to an RC because they seem to be released so frequently and I have no idea if one is more or less stable than another. This uncertainty is a big show-stopper to upgrading. It would help if, for a given RC, we knew exactly what known issues that RC had. (Is that in the wiki?) I'd suggest that a "version" be assigned only to something that should get spread around. A nightly snapshot should get the version it was based from and a timestamp suffix of when it was extracted from CVS. (Were this Subversion, I'd append the repository revision, instead.) The snapshot is not a "version" but a convenient download from CVS. It should be exactly what you get with the same timestamp used in a checkout command. Apache's versioning scheme (posted by John Peacock) looks good to me: <http://apr.apache.org/versioning.html>

[Dovecot] Forbidding folder delete
by Kenneth Porter 30 Mar '07

30 Mar '07

Is there some way I can forbid the deleting of folders? I have a Thunderbird user who twice now has accidentally deleted a folder, forcing me to go fetch it from the nightly backup. I'd like to prevent this from happening again, and the easiest way to me is to block folder deletion. I'd rather do that "manually" from the shell than leave it available from the client GUI.

[Dovecot] Copy to sent mail timeouts
by Jeff Tucker 29 Mar '07

29 Mar '07

Hi. I'm running the dovecot IMAP that comes with Ubuntu Edgy, which is 1.0rc2. I realize this is old, but I'll ask my question in case anyone knows about this problem and how to fix it, or knows that a later version definitely fixes it. What I'm seeing is that the IMAP server works perfectly, except for occasional timeouts when the user sends an email with attachments, causing that email then to be copied to their sent mail folder. The behavior seen is that Thunderbird, for instance, will say it is copying to the sent mail and the progress goes up to 100%, but then stops and Thunderbird eventually says the action timed out. I don't see anything in any dovecot logging and the file does not appear in the sent mail. I don't have any other kind of timeout issues. I can move mails around folders, read large emails, or whatever. The problem seems worse with large emails, but some times it will copy 15 MB emails and some times it won't. I can't find that any particular email always fails. Any ideas? As a last resort, I'll build the latest rc from scratch, but I like the automatic installation, notification of security problems, etc. I get with the distro packages. Thanks Jeff

[Dovecot] chroot and raw logging

I'm not sure if it's even intended to work in this particular case, but there's a problem when chroot is explicitely defined and rawlogging is used. Rawlog respects chroot point, without being actually chrooted. Consider configurtion as below, with two cases (dovecot.rawlog dir is of course created earlier, with appropriate uid/gid). 1) dovecot.userdb: test::10000:10000::/home/vmail/test.tld/test/./::userdb_mail=maildir:~/Maildir: ktrace will show: 18206 rawlog CALL sigprocmask(0x3,0) 18206 rawlog RET sigprocmask -65793/0xfffefeff 18206 rawlog CALL lstat(0x81fbe028,0xcfbcc980) 18206 rawlog NAMI "/dovecot.rawlog" 18206 rawlog RET lstat -1 errno 2 No such file or directory 18206 rawlog CALL sigprocmask(0x1,0xffffffff) 2) dovecot.userdb: test::10000:10000::/home/vmail/test.tld/./test::userdb_mail=maildir:~/Maildir: 1116 rawlog CALL lstat(0x85768028,0xcfbc1d20) 1116 rawlog NAMI "test/dovecot.rawlog" 1116 rawlog RET lstat -1 errno 2 No such file or directory 1116 rawlog CALL sigprocmask(0x1,0xffffffff) 1116 rawlog RET sigprocmask 0 I also noticed something else (not rawlog related). If I do a silly (blame my curiosity ;) thing like: valid_chroot_dirs: / and set chroot point as /./home/vmail/test.tld/test/ in passwd-file Dovecot will try to stat home/vmail/test.tld/test/ (and fail w/o beginning /), then chdir to /tmp, start pop3 or imap process, and recreate home/vmail/test.tld/test under /tmp. 17027 dovecot CALL chdir(0x87a4b29c) 17027 dovecot NAMI "home/vmail/test.tld/test/" 17027 dovecot RET chdir -1 errno 2 No such file or directory 17027 dovecot CALL setitimer(0,0xcfbe7020,0xcfbe7010) 17027 dovecot RET setitimer 0 17027 dovecot CALL seteuid(0) 17027 dovecot RET seteuid 0 17027 dovecot CALL chdir(0x3c001b72) 17027 dovecot NAMI "/tmp" 17027 dovecot RET chdir 0 ... 17027 dovecot CALL sigprocmask(0x3,0) 17027 dovecot RET sigprocmask -65793/0xfffefeff 17027 dovecot CALL execve(0x87a4bc38,0x87a4bc70,0x84fdb900) 17027 dovecot NAMI "/usr/local/libexec/dovecot/pop3" ... 17027 pop3 CALL mkdir(0x85f5a2b0,0x1ff) 17027 pop3 NAMI "home/vmail/test.tld/test//Maildir" 17027 pop3 RET mkdir -1 errno 2 No such file or directory 17027 pop3 CALL mkdir(0x85f5a2e0,0x1ff) 17027 pop3 NAMI "home/vmail/test.tld/test/" 17027 pop3 RET mkdir -1 errno 2 No such file or directory 17027 pop3 CALL mkdir(0x85f5a328,0x1ff) 17027 pop3 NAMI "home/vmail/test.tld/test" 17027 pop3 RET mkdir -1 errno 2 No such file or directory 17027 pop3 CALL mkdir(0x85f5a348,0x1ff) ... and so on, then it creates all the home/vmail/... dirs Configuration: openbsd 3.9, i386, dovecot 1.0-rc28 dovecot.userdb: test::10000:10000::/home/vmail/test.tld/test/./::userdb_mail=maildir:~/Maildir: dovecot.passdb: test:{PLAIN}test: base_dir: /var/dovecot/ protocols: imap imaps pop3 pop3s ssl_listen: * ssl_ca_file: /etc/ssl/cert_bundle.pem ssl_cert_file: /etc/ssl/ca_ppgk/certs/fetch_crt.pem ssl_key_file: /etc/ssl/ca_ppgk/private/fetch_key.pem verbose_ssl: yes login_dir: /var/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login login_greeting: Dovecot IMAP server ready. login_greeting_capability(default): yes login_greeting_capability(imap): yes login_greeting_capability(pop3): no valid_chroot_dirs: /var/mail:/home/regular:/home/vmail verbose_proctitle: yes first_valid_uid: 1999 first_valid_gid: 10 mail_location: mbox:~/Mail:INBOX=/var/mail/%u mail_debug: yes fsync_disable: yes lock_method: fcntl maildir_copy_with_hardlinks: yes mbox_read_locks: fcntl mbox_write_locks: fcntl mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 imap_client_workarounds(default): outlook-idle delay-newmail imap_client_workarounds(imap): outlook-idle delay-newmail imap_client_workarounds(pop3): outlook-idle pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: mechanisms: plain login verbose: yes debug: yes passdb: driver: passwd-file args: /etc/dovecot.passdb passdb: driver: bsdauth userdb: driver: passwd-file args: /etc/dovecot.userdb userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master:

I expected: * PAM authentication would not be attempted * passwd-file would provide gid, uid, home, mail I notice that even thought it appears that this information is returned from auth(default) in the IMAP(randykahle) phase, it is not using that information - it used uid=502, etc. Here is my log output: ----- Mar 29 05:59:08 kahle dovecot: auth(default): pam(randykahle, 72.211.130.251): lookup service=dovecot Mar 29 05:59:08 kahle dovecot: auth(default): pam(randykahle, 72.211.130.251): pam_authenticate() failed: Authentication failure Mar 29 05:59:08 kahle dovecot: auth(default): passwd-file /etc/ dovecot/userdb: Read 1 users Mar 29 05:59:08 kahle dovecot: auth(default): passwd-file(randykahle, 72.211.130.251): lookup: user=randykahle file=/etc/dovecot/userdb Mar 29 05:59:08 kahle dovecot: auth(default): client out: OK 1 user=randykahle home=/var/mail/vhosts/com.rosalita/ randy mail=maildir:~/Maildir uid=5000 gid=5000 Mar 29 05:59:08 kahle dovecot: auth(default): master in: REQUEST 26 11935 1 Mar 29 05:59:08 kahle dovecot: auth(default): passwd(randykahle, 72.211.130.251): lookup Mar 29 05:59:08 kahle dovecot: auth(default): master out: USER 26 randykahle system_user=randykahle uid=502 gid=502 home=/ home/randykahle Mar 29 05:59:08 kahle dovecot: IMAP(randykahle): Effective uid=502, gid=502, home=/home/randykahle Mar 29 05:59:08 kahle dovecot: IMAP(randykahle): maildir: access(/ home/randykahle/Maildir, rwx): failed: No such file or directory Mar 29 05:59:08 kahle dovecot: IMAP(randykahle): maildir: couldn't find root dir Mar 29 05:59:08 kahle dovecot: IMAP(randykahle): mbox: root exists (/ home/randykahle/mail) Mar 29 05:59:08 kahle dovecot: IMAP(randykahle): mbox: INBOX exists (/ var/mail/randykahle) Mar 29 05:59:08 kahle dovecot: IMAP(randykahle): mbox: root=/home/ randykahle/mail, index=/home/randykahle/mail, inbox=/var/mail/randykahle Mar 29 05:59:08 kahle dovecot: imap-login: Login: user=<randykahle>, method=PLAIN, rip=72.211.130.251, lip=72.249.22.55 Mar 29 05:59:11 kahle dovecot: IMAP(randykahle): open(/var/ mail/.temp.kahle.org.11965.76100dca2c5b2009) failed: Permission denied Mar 29 05:59:11 kahle dovecot: IMAP(randykahle): file_lock_dotlock() failed with mbox file /var/mail/randykahle: Permission denied Mar 29 05:59:16 kahle dovecot: IMAP(randykahle): Disconnected ----- Here is my passwd-file user information line: ----- randykahle:{plain}xxxxx:5000:5000::/var/mail/vhosts/com.rosalita/ randy::home=/var/mail/vhosts/com.rosalita/randy mail=maildir:~/ Maildir uid=5000 gid=5000 ----- Any tips on how to get the information in the passwd-file used by the IMAP process would be appreciated. -- Randy

[Dovecot] can't receive mail from other hosts
by carpenter＠strongs.org 29 Mar '07

29 Mar '07

i'm running RHEL v 5 and 1.0-1.2.rc15 of dovecot and 2.3.3-2 of postfix. users can send mail to outside hosts, but can not receive them. i find no errors in the maillog -- i used a page from the redhat docs to configure postfix and dovecot so that they used the same mail directory... i think... any ideas on how to debug and/or fix this would be greatly appreciated. thanks, steve

[Dovecot] New mail not appearing consistently in Outlook 2003
by Karl von Randow 29 Mar '07

29 Mar '07

Hi all, I have continuously experienced a new mail not appearing problem in Outlook 2003 on Windows XP. Using Dovecot 0.99.14 on Debian Sarge and now in 1.0rc26 and rc27. The problem exhibits itself as: Some new mail is randomly(?) not shown in my mailbox. More new mail does appear, so it's difficult to know when a message has been missed. If I restart Outlook the missed new messages will appear as unread in the order where they should have been received in my inbox. I use secure imap. I get email through my inbox (receipts from a website we're testing, at its peak maybe 2-3 a minute) that are moved into another mailbox using a rule in Outlook. These are often the messages that are missed as above, but it often includes other email as well. The mail box format is mbox on the server. The mail delivery is by exim4 from Debian Sarge. I wondered if there was a locking problem between exim4 and dovecot? My transport in exim4 for delivering the mail is: mail_spool_home: debug_print = "T: appendfile for $local_part@$domain" driver = appendfile file = /home/vmail/$domain/$local_part/INBOX delivery_date_add envelope_to_add return_path_add group = mail mode = 0660 mode_fail_narrower = false The problem is reproducable in that I see the problem occur everyday. I am about to compile and install rc28 to see if that improves matters. I'd appreciate any help resolving the problem! Here is my dovecot.conf: # /usr/local/etc/dovecot.conf protocols: pop3 imap imaps disable_plaintext_auth: no login_dir: /usr/local/var/run/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login mail_extra_groups: mail mail_location: mbox:/home/vmail/%d/%n/mail/:INBOX=/home/vmail/%d/%n/INBOX mbox_dirty_syncs: no mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 imap_client_workarounds(default): outlook-idle delay-newmail imap_client_workarounds(imap): outlook-idle delay-newmail imap_client_workarounds(pop3): outlook-idle pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv auth default: passdb: driver: passwd-file args: /etc/vmail.passwd userdb: driver: static args: uid=1064 gid=1001 home=/home/vmail/%d/%u

[Dovecot] Bug-report for rc28: Mailbox isn't a valid mbox file
by Erik van Oosten 29 Mar '07

29 Mar '07

Hi, When I try to open the attached mbox file I get the following warning in Thunderbird 1.5.0.10: 'The current command failed. The e-mail server responded: Mailbox isn't a valid mbox file'. I also tried this with squirrelmail, with the same result. The Dovecot version is dovecot-1.0.rc28, compiled from source. The attached mbox was correctly read from, and written to in earlier versions (either rc15 or rc22, I am not sure). The initial import was done (a long time ago) by copying a file from my Thunderbird profile directory. OS: SuSE 10.0, x86 Filesystem: ext3, (no NFS) Output of dovecot -n: ------------------------------------ # /usr/local/etc/dovecot.conf disable_plaintext_auth: no login_dir: /usr/local/var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login mail_location: mbox:~/mail:INBOX=/var/spool/mail/%u auth default: passdb: driver: pam userdb: driver: passwd ------------------------------------- Can I somehow recover the data in this mbox?

[Dovecot] odd behavior with Dovecot LDA
by Steven F Siirila 29 Mar '07

29 Mar '07

Okay, to convince myself that quota handling was working okay with Dovecot 1.0-rc27 on Solaris 10, I tested sending a message to an account that was purposely over-quota. The account in question had a vacation message set up. For the first test, there was no $HOME/.imap directory at all. I received the vacation message, but the message which was supposed to be delivered locally queued in Postfix (temporary failure). For the second test, I created $HOME/.imap and $HOME/.imap/INBOX directories with the owner and group set to that of the user (just to make sure the code handled things the same). Again, I received the vacation message, but the message which was supposed to be delivered locally bounced back to me after Dovecot LDA crashed: <syst0005(a)peridot.tc.umn.edu>: Command died with status 139: "/opt/dovecot/libexec/dovecot/deliver -f "$SENDER"". Command output: Segmentation Fault It appears that Dovecot LDA assumes that if .imap/FOLDERNAME exists that the index files must also exist.. I wonder what other assumptions might cause segfaults. -- Steven F.

[Dovecot] How do I check the release #?
by Randolph Kahle 29 Mar '07

29 Mar '07

I am a dovecot newbie and I am setting up a machine that already has dovecot installed. Since bugs are being resolved rapidly, it appears that I need to know the release version of dovecot I am running. Is there a command I can issue or a file I can examine to determine the release version of my installation? -- Randy

[Dovecot] transfer files from Plesk qmail to Dovecot and Postfix
by Frank Church 29 Mar '07

29 Mar '07

I have some files I want to transfer from Plesk qmail to Postfix with virtual mailboxes, MySQL, Maildir etc. I can add the accounts to the database manually as there are only a few of them. In the case of the mail folders, is it merely a matter of copying the mail files over, or are there some adjustments to be made to the files? I have noticed the thread about the Courier to Dovecot script and I wonder whether it may have a role in this process.

[Dovecot] auth server refusing connections intermittently
by Steven F Siirila 28 Mar '07

28 Mar '07

Running Dovecot 1.0-rc27 on Solaris 10.. We have been noticing intermittent messages of this sort and wondered if this indicates whether we need to add more dovecot-auth worker processes: Mar 28 03:15:41 myhost dovecot: pop3-login: Can't connect to auth server at default: Connection refused Mar 28 08:10:20 myhost dovecot: imap-login: Can't connect to auth server at default: Connection refused Mar 28 09:08:13 myhost dovecot: imap-login: Can't connect to auth server at default: Connection refused Mar 28 10:23:38 myhost dovecot: imap-login: Can't connect to auth server at default: Connection refused Mar 28 10:35:37 myhost dovecot: imap-login: Can't connect to auth server at default: Connection refused Mar 28 10:50:59 myhost dovecot: imap-login: Can't connect to auth server at default: Connection refused Mar 28 12:00:44 myhost dovecot: pop3-login: Can't connect to auth server at default: Connection refused Mar 28 12:07:31 myhost dovecot: imap-login: Can't connect to auth server at default: Connection refused Mar 28 14:44:57 myhost dovecot: imap-login: Can't connect to auth server at default: Connection refused However, this system has over 7,000 users and 1,500 simultaneous IMAP and POP3 connections, and we only see one dovecot-auth process running. By contrast, another server has over 11,000 users and 3,000 simultaneous IMAP and POP3 connections (but is currently running rc24), and we only have seen 3 of the above error messages there -- and there is only one dovecot-auth process there as well. Does this sound right? Also, how many times are these connections retried (and at what sleep interval, if any) before it gives up? -- Steven F.

[Dovecot] Removing users maildir DOVECOT+LDAP

Hi all, Does anyone have an idea how can I remove(delete) my virtual mail users' maildir? I have Dovecot + LDAP and I would like to do something like this: When I remove an user entry in my ldap server, it should remove my user directory information. Does anyone has this implemented? Or have an idea? I can remove users entry in my ldap server remotely, is there some way in dovecot? I'm asking this, cause I'm very familiar with Cyrus and I can do this with it.

[Dovecot] Deliverm, vpopmail, and valias
by John Peacock 28 Mar '07

28 Mar '07

I'm in the final stages of testing my e-mail server to come and I seem to have hit a roadblock. One option of current vpopmail is to store all aliases in a valias table, that looks like this: +-------------+----------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +-------------+----------+------+-----+---------+-------+ | alias | char(32) | NO | MUL | | | | domain | char(64) | NO | | | | | valias_line | text | NO | | | | +-------------+----------+------+-----+---------+-------+ where valias_line could be either an e-mail address (preceded by an ampersand) or a command (piped to vacation for example). I have already accepted a message for an aliased address, but the MTA isn't going to be rewriting the envelope address, so how can I get dovecot's deliver to dereference the alias and deliver to the correct Inbox? Because of the number of other hops[1] that the message is going through, I don't want to rewrite the destination address unless I really have to, but if that is the only option, that is what I'll have to do. Thoughts? John 1) inbound e-mail hits a qpsmtpd instance which validates e-mails using several different filtering techniques. Next the mail gets fed to a dspam appliance running two Postfix queues (one before dspam and one after). Mail that isn't quarantine by dspam gets sent to the delivery server (currently running qmail) and delivered to the final destination (modulo sieve rules under deliver). The only place I could conceivably rewrite the address would be the second Postfix queue. -- John Peacock Director of Information Research and Technology Rowman & Littlefield Publishing Group 4501 Forbes Boulevard Suite H Lanham, MD 20706 301-459-3366 x.5010 fax 301-429-5748

[Dovecot] ignoring some subfolders [potential wishlist]
by Arkadiusz Miskiewicz 28 Mar '07

28 Mar '07

Hello I'm looking at migration path from my current setup (tpop3d/courier-imap) and I seem to miss one feature - ability to ignore some subfolders for pop3. tpop3d allows me to say: maildir-ignore-folders: Spam Trash trash Sent sent-mail POP3-Invisible (would be stupid to fetch own sent-mail via pop3 again 8-) In recent tpop3d cvs version I can also use regexps like maildir-ignore-folders: ^IMAP-Only.*$. Is it possible to ignore some subfolders in dovecot per protocol (like for pop3 only and not imap) ? If not then please consider this as wishlist, maybe in form of location negation like: mail_location = \ maildir:/var/mail/%Lu:!maildir:/var/mail/%Lu/.Something (which doesn't look sane) or with separate config directive like in tpop3d -- Arkadiusz Miśkiewicz PLD/Linux Team arekm / maven.pl http://ftp.pld-linux.org/

Hello, I have a problem (at least with 1.0rc28 and 1.0rc27) when using the following namespace definitions: namespace private { separator = "/" inbox = yes location = mbox:~/Mail:INBOX=/var/spool/mail/%u } namespace public { separator = / prefix = 0-LISTS/ location = mbox:/var/mail/lists:INDEX=~/.sharedMail/lists/index } namespace private { separator = "/" prefix = "0-MAILDIR-FOLDERS/" location = maildir:~/Maildir } IMAP access is working as expected, but when connecting with POP3(s), the (mostly empty in our case) ~/Maildir is used as mail location when it has been created (including index files) by IMAP access. If ~/Maildir does not exist/has been deleted again, POP3 uses /var/spool/mail/%u. This is independent of the private namespace section order and also an explicit "inbox = no" in 0-MAILDIR-FOLDERS namespace. Any idea if this is an configuration issue I don't understand yet or a bug?

[Dovecot] Allow/disallow mail access based on group membership
by Taras Savchuk 28 Mar '07

28 Mar '07

I'm just finished FreeBSD/AD integration via Kerberos/LDAP and now I can manage unix users/groups from AD. I want to grant access to IMAP based on user membership in certain group. Is it possible? Can you give me some hints? Thanks in advance! -- С уважением, Савчук Тарас ООО "Элантек" : Аутсорсинг ИТ, WEB-разработка http://www.elantech.ru +7 (495) 589 68 81 +7 (926) 575 22 11

[Dovecot] LDAP group quota support
by Ioannis Zachariadis 28 Mar '07

28 Mar '07

Is there a plan to support LDAP group quotas in the future releases ? Just like the ldap quota plugin for users but with additional support for a unified quota for a group users. -- giannis.

[Dovecot] proxy host specified as fqdn in userdb
by Apostolos Papayanakis 28 Mar '07

28 Mar '07

Abstract from http://wiki.dovecot.org/PasswordDatabase/ExtraFields/Proxy > > host=s: The destination server's *IP address*. This field is required. > Note that currently it's required to use an IP address since no DNS > resolving is done. > Hello Timo, Here goes one more item for the v2.0 wishlist: Will it become possible to do dovecot imap proxying based on a "host" userdb attribute that is an FQDN (instead of a numeric IP as it is now)? It would simplify things for large smtp clusters that already do LDAP mail routing, based on per user "mailHost" attribute containg mail server FQDNs (according to "IETF Internet Draft LDAP Schema for Intranet Mail Routing", http://www.sendmail.org/m4/laser.txt) It is kinda redundunt to keep an extra LDAP attribute for "host" that contains essentially the same information as "mailHost" attribute, but in numeric form. I know the proposed change is not that important for many people, so don't really bother unless it is trivial to implement. apap

[Dovecot] rc2x seems to break Pegasus Mail
by Rick Romero 28 Mar '07

28 Mar '07

Hi guys, I upgraded from rc7 to rc24 a couple weeks ago, and noticed today that Pegasus Mail's IMAP no longer connects. So I put rc27 in, and it worked, but only for a little while... I'm not sure what the problem might be, the logs look fine, and I can still use Horde and Evolution without a problem. Pegasus Mail's error is unfortunately not helpful. Restarting rc27 didn't 'bring it back' for Pegasus. I turned on debugging, but I don't know what to look for because other clients work :/ dovecot: Mar 22 09:55:58 Info: imap-login: Login: user=<rick>, method=PLAIN, rip=172.16.100.20, lip=172.16.100.10, TLS dovecot: Mar 22 09:55:58 Info: IMAP(rick): Loading modules from directory: /usr/local/lib/dovecot/imap dovecot: Mar 22 09:55:58 Info: IMAP(rick): Module loaded: /usr/local/lib/dovecot/imap/lib10_quota_plugin.so dovecot: Mar 22 09:55:58 Info: IMAP(rick): Module loaded: /usr/local/lib/dovecot/imap/lib11_imap_quota_plugin.so dovecot: Mar 22 09:55:58 Info: IMAP(rick): Effective uid=89, gid=89, home=/usr/home/vpopmail/domains/havokmon.com/rick dovecot: Mar 22 09:55:58 Info: IMAP(rick): Namespace: type=private, prefix=INBOX., sep=., inbox=yes, hidden=no, subscriptions=no dovecot: Mar 22 09:55:58 Info: IMAP(rick): maildir: root exists (/usr/home/vpopmail/domains/havokmon.com/rick/Maildir) dovecot: Mar 22 09:55:58 Info: IMAP(rick): maildir: root=/usr/home/vpopmail/domains/havokmon.com/rick/Maildir, index=/usr/home/vpopmail/domains/havokmon.com/rick/Maildir, control=, inbox= dovecot: Mar 22 09:56:03 Info: imap-login: Login: user=<rick>, method=PLAIN, rip=172.16.100.20, lip=172.16.100.10, TLS dovecot: Mar 22 09:56:03 Info: IMAP(rick): Loading modules from directory: /usr/local/lib/dovecot/imap dovecot: Mar 22 09:56:03 Info: IMAP(rick): Module loaded: /usr/local/lib/dovecot/imap/lib10_quota_plugin.so dovecot: Mar 22 09:56:03 Info: IMAP(rick): Module loaded: /usr/local/lib/dovecot/imap/lib11_imap_quota_plugin.so dovecot: Mar 22 09:56:03 Info: IMAP(rick): Effective uid=89, gid=89, home=/usr/home/vpopmail/domains/havokmon.com/rick dovecot: Mar 22 09:56:03 Info: IMAP(rick): Namespace: type=private, prefix=INBOX., sep=., inbox=yes, hidden=no, subscriptions=no dovecot: Mar 22 09:56:03 Info: IMAP(rick): maildir: root exists (/usr/home/vpopmail/domains/havokmon.com/rick/Maildir) dovecot: Mar 22 09:56:03 Info: IMAP(rick): maildir: root=/usr/home/vpopmail/domains/havokmon.com/rick/Maildir, index=/usr/home/vpopmail/domains/havokmon.com/rick/Maildir, control=, inbox= dovecot: Mar 22 09:56:03 Info: IMAP(rick): Disconnected: Logged out Config: base_dir = /var/run/dovecot/ protocols = imap imaps listen = * disable_plaintext_auth = no shutdown_clients = yes log_path = /var/log/dovecot/dovecot.log info_log_path = /var/log/dovecot/dovecot_info.log log_timestamp = "%b %d %H:%M:%S " ssl_cert_file = /usr/local/share/courier-imap/mail-vfemail-godaddy.crt ssl_key_file = /usr/local/share/courier-imap/mail-vfemail-godaddy.key ssl_key_password = verbose_ssl = no login_dir = /var/run/dovecot/login login_user = nobody login_process_size = 64 login_process_per_connection = yes login_processes_count = 15 login_max_processes_count = 512 login_greeting = VFEmail IMAP Dovecot ready. namespace private { separator = . prefix = INBOX. inbox = yes } mail_debug = no mmap_disable = yes verbose_proctitle = yes first_valid_uid = 89 last_valid_uid = 0 protocol imap { mail_plugins = quota imap_quota imap_client_workarounds = outlook-idle } protocol pop3 { } protocol lda { postmaster_address = admin(a)vfemail.net } auth_verbose = no auth_debug = no auth default { mechanisms = plain passdb checkpassword { args = /usr/local/vpopmail/bin/vchkpw } userdb prefetch { } user = vpopmail } dict { } plugin { quota = maildir } I compiled both rc2x's with just ./configure Install prefix ...................... : /usr/local File offsets ........................ : 64bit I/O loop method ..................... : poll File change notification method ..... : none Building with SSL support ........... : yes (OpenSSL) Building with IPv6 support .......... : yes Building with pop3 server ........... : yes Building with mail delivery agent .. : yes Building with GSSAPI support ........ : no Building with user database modules . : static prefetch passwd passwd-file checkpassword vpopmail (modules) Building with password lookup modules : passwd passwd-file pam checkpassword vpopmail (modules) Building with SQL drivers ............: Though - for rc27, I had to disable vpopmail because it wouldn't build.

[Dovecot] rc29 and documentation changes
by Timo Sirainen 28 Mar '07

28 Mar '07

http://dovecot.org/nightly/dovecot-latest.tar.gz Any comments about the doc/wiki/ contents? doc/documentation.txt? dovecot-example.conf's doc/wiki/ pointers? ./autogen.sh now updates the wiki from http://www.dovecot.org/tmp/wiki-export.tar.gz (updated each night) if doc/wiki/Authentication.txt doesn't exist. I guess I'll release rc29 tomorrow. The current changes are: + 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

[Dovecot] MANAGESIEVE patch v3 for dovecot 1.0.rc28
by Stephan Bosch 28 Mar '07

28 Mar '07

Hello dovecot users, I have updated the MANAGESIEVE patch to apply and compile against dovecot 1.0.rc28. Not much has changed with respect to the functionality of the previous version however: ChangeLog vs v2 - Updated source to compile with dovecot 1.0.rc28, tested with rc27 (debian package) - Daemon now uses the same location for .dovecot.sieve as dovecot-lda This is typically ~/.dovecot.sieve. - If .dovecot.sieve is a regular file, it is now moved into the script storage as dovecot.orig.sieve, preventing deletion of (important) active scripts upon managesieve installation. Otherwise, it would simply be replaced by a symlink to the new active script. - Changed error handling to yield a BYE message when the managesieve daemon exits unexpectedly (upon login) before any commands are entered. Horde-ingo would wait indefinitely for a response. This patch still includes (yet another) instance of the CMU Sieve source, as explained in my previous mail (http://dovecot.org/list/dovecot/2006-July/015016.html) It can be downloaded at: http://sinas.rename-it.nl/~sirius/dovecot-1.0.rc28-MANAGESIEVE-v3.diff.gz Have fun testing the patch. Notify me when there are problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl IRC: Freenode, #dovecot, S[r]us

[Dovecot] gssapi auth issue...
by Dan Price 28 Mar '07

28 Mar '07

Hi all-- been away from the list for a few weeks so forgive me if this problem has been reported-- with the help of some of our Kerberos engineers, we tracked down why we can't authenticate our Solaris kerberos clients to Dovecot. Here's the deal: Our IT organization issued us kerberos tickets of the form imap(a)foobar.sfbay.sun.com Which I presume is their standard-- and probably not negotiable. However, the hostname of the machine is: "foobar", not foobar.sfbay.sun.com (as reported by gethostname(3c)). So when dovecot does this: mech-gssapi.c: principal_name = t_str_new(128); str_append(principal_name, service_name); str_append_c(principal_name, '@'); ---> str_append(principal_name, my_hostname); We wind up asking kerberos to look for a ticket for imap@foobar, instead of imap(a)foobar.sfbay.sun.com. Obviously we can patch the source, but I was wondering if we could have a gssapi_hostname setting in the config file? Or perhaps we could have a knob letting us globally override my_hostname? Although I don't know what side effects that could have. We have some new cores I also need to report-- I'll get on that. Thanks in advance, -dp -- Daniel Price - Solaris Kernel Engineering - dp(a)eng.sun.com - blogs.sun.com/dp

[Dovecot] Custom Mail Directory for some users
by Patrick Kranz 27 Mar '07

27 Mar '07

Hi list, I'm new on this mailing list and I'm kind of stucked at the moment. I managed to get Postfix and Dovecot working together with Amavis, OpenLDAP und SASL on Ubuntu Linux Release "Dapper Drake". The Dovecot version shipped with Dapper is 1.0-beta3 (at least, that's what the package database tells me), I also tried this with a Debian Backport of version 1.0-rc15. And here is my problem: A customer of mine needs usernames different from the mail address for his third party software to work. In other words, I need the ability to login with the username foo to get access to the mailbox bar(a)example.com. So I tried to override the mail_location property for this user with a separate mailDirectory attribute in my LDAP tree. Speaking in dovecot.conf words: mail_location = maildir:/var/spool/dovecot/mail/%d/%n auth default { machanisms = plain passdb ldap { args = /etc/dovecot/dovecot-ldap.com } userdb ldap { args = /etc/dovecot/dovecot-ldap.com } userdb static { args = uid=vmail gid=vmail user = dovecot } and dovecot-ldap.conf: hosts = localhost dn = cn=admin,dc=ekits,dc=de dnpass = secret auth_bind = yes ldap_version = 3 base = ou=mailsystem,dc=ekits,dc=de scope = subtree user_attrs = mailDirectory=mail user_filter = (&(objectClass=ekitsMailAccount)(uid=%u)) pass_attrs = uid=user,userPassword=password pass_filter = (&(objectClass=ekitsMailAccount)(uid=%u)) user_global_uid = vmail user_global_gid = vmail a typical ldap entry looks something like this: dn: cn=Patrick Kranz,o=EK IT-Solutions,ou=mailsystem,dc=ekits,dc=de ekitsMailDestination: patrick(a)ekits.de objectClass: ekitsMailAccount objectClass: top cn: Patrick Kranz structuralObjectClass: ekitsMailAccount entryUUID: b4ebb9e8-6d8d-102b-9dc9-9edb870845a4 creatorsName: cn=admin,dc=ekits,dc=de createTimestamp: 20070323132526Z userPassword:: YVBhc3M= mailDirectory: maildir:/var/spool/dovecot/mail/ekits.de/blubb uid: patrick As far as I can interpret the log of slapd, dovecot doesn't even ask for the attribute "mailDirectory". I also tried this with userdb prefetch. With this it did actually ask for the attribute but it still had no effect. With this configuration dovecot creates the directory /var/spool/spool/dovecot/mail/patrick if I login with the uid patrick but I wanted access to /var/spool/dovecot/mail/ekits.de/blubb If anybody has any clue what I did wrong or if I have a conceptional misunderstanding, I would appreciate every help. Thanks in advance. Greetings, Patrick

[Dovecot] Sync of read message status between squirrelmail and outlook express
by Mohd Ikhwan Abdullah 27 Mar '07

27 Mar '07

Hi, We have a Linux email server running CentOS 4.4. I have a scenario here. The users here use a mixture of outlook express and squirrel mail as their email client. The users download their mail into outlook express via pop3 but the have configured outlook express to leave a copy on the server for 7 days. 1. After downloading the mail into outlook express the users would read the mail and the mail would be set as 'READ' in outlook express. 2. Is there a way to configure dovecot so that the 'READ' status in outlook express is reflected on the message still stored on the server as well. Cause when they access via squirrel mail the message is still mark as 'UNREAD'. Any suggestions is very much appreciated. Thanks in advance.

[Dovecot] LDA bouncing mails after upgrade
by Milan Holzäpfel 27 Mar '07

27 Mar '07

Hello, on my system, I have a copy of /usr/libexec/dovecot/deliver located in /usr/libexec/dovecot/postfix-deliver/deliver (only accessible to postfix and with SUID root permissions). If I happen to forget to update this copy after an upgrade of dovecot, the deliver LDA bounces mails: | Mar 22 20:29:20 host.example.org deliver(user(a)example.org): Module is for different version 1.0.rc27: /usr/lib/dovecot/lda/lib10_quota_plugin.so | Mar 22 20:29:20 host.example.org postfix/pipe[17344]: <ID>: to=<user(a)example.org>, relay=dovecot, delay=1.9, delays=1.5/0/0/0.35, dsn=5.3.0, status=bounced (Command died with status 89: "/usr/libexec/dovecot/postfix-deliver/deliver") Should I just set version_ignore=yes and remember myself to upgrade it, or could deliver return a code signaling "temporary failure", or should I rather make postfix interpret 89 as temporary failure? (don't know by heart whether that's possible). Regards, Milan -- Milan Holzaepfel <mail(a)mjh(d)name> <URL:http://mjh.name/> pub 4096R/C790FC23 EB8E 5E81 81E3 53A9 9B74 B895 5179 54C0 C790 FC23

[Dovecot] netapp/maildir/dovecot performance
by bofh list 26 Mar '07

26 Mar '07

We are seeing some poor performance recently that is focused around users with large mailboxes (100,000 message /INBOX, 80,000 message subfolders, etc). The performance problem manifests as very high system% utilization - basically iowait for NFS. There are two imap servers with plenty of horsepower/memory/etc. They are connected to a 3050c cluster via gig-e. Here are the mount options: rw,tcp,nfsvers=3,rsize=8192,wsize=8192,nosuid,nodev,soft,intr,noac,actimeo=0 I need to get this system% utilization brought down because it is starting to slowdown imap performance for other users (it goes up to 95% on a regular basis, with users that have folders with many messages). My thought is to try removing the noac option and bump up the actimeo value from 0 to 30. Unfortunately I don't have access to use a SLB to direct traffic to individual servers. My understanding is that the worst that can happen is index corruption (which will result in rebuilding them when it happens). Any thoughts? I'm running RC24.

[Dovecot] Unwanted INBOX. prefix issues
by Kevin Bowling 26 Mar '07

26 Mar '07

I have a strange problem. I installed Dovecot and had my trash folder and such in the root of my maildir, and everything was working great. I then installed SquirrelMail which created folders in with the INBOX. prefix. I manually removed these from the maildir, but the INBOX.Trash is still shown in the folder listing of Thunderbird. This leads to some strange behavior, such as the delete button not working. Is there a way I can reset the folder list, and take the INBOX.* items out? Any help would be appreciated. Regards, Kevin

[Dovecot] Rpm builders: Dovecot spec file
by Egbert Jan 26 Mar '07

26 Mar '07

Maybe best asked to Axel... I'm re-building my server from scratch (the old one was MDK 10.1 -> Mandriva 2006.0 with Postfix/Courier) and I want to install the latest versions postfix/mysql/postfixadmin/dovecot/squirrelmail. I've been building Dovecot (and postfix) from tarballs/srpm in the past so I know more or less how it all fits together. But I wonder if 'old' patches still need to be included/applied in the building of the latest rc's. I still see references to those patches in the spec file. Unfortunately the latest 'official' rpm for Mandriva (I'm running 2007.0) is rc7 and I never succeeded getting in contact with the Mandriva maintainer to ask the same question. In the Axel's AT rpm I still see some patches included but others than in the Mandriva rc7 spec file. Are those patches not already applied to the latest sources by Timo? Tnx Egbert Jan NL

[Dovecot] Bug tracking system
by Timo Sirainen 26 Mar '07

26 Mar '07

There are three reasons why I haven't really bothered setting up a bug tracking system for Dovecot: 1) They're all kind of annoying to use. 2) They all require a lot of stuff like PHP, SQL server, etc. which I don't really want to put into dovecot.org. 3) Probably most importantly: If people start reporing bugs in there, I'm pretty much the only person who will ever read them and reply to them. Currently when people report bugs in here, it's quite useful to have other people read them too. They may already know the bug and say they've reported it, they may have an idea what's causing it, they may know a workaround, etc. All in all, moving things to BTS would most likely cause my life to be harder and it might be more difficult to get some bugs fixed. A couple of days ago I started thinking about this and then I figured out a way to solve all of this nicely with a new and great Dovecot based bug tracking system. :) Just so I won't forget it, here's the plan: Dovecot BTS ----------- The preferred way to report bugs is to send them to dovecot-bugs(a)dovecot.org. The only thing it does is prefix the subject line with [BUG #nnn] and forward it to dovecot(a)dovecot.org. Now everyone can reply to it just as it was a normal mailing list mail. As long the subject contains the "[BUG #nnn]" prefix, it's part of the bug. Existing mailing list threads can also be turned into bugs by replying to the thread's root message with To: dovecot-bugs(a)dovecot.org. This again causes the new reply to contain [BUG #nnn] prefix. Then comes the web part. There's no SQL database or anything, everything is stored in a mailbox in the IMAP server. The mailbox contains the whole dovecot(a)dovecot.org archive. Bug metadata such as priority, status, etc. is stored using IMAP ANNOTATE extension, which allows setting key=value pairs to messages. Unfortunately Dovecot doesn't yet support that extension. Bugs' root messages contain the annotations for the whole bug thread. So to get a list of all bugs, the BTS issues an IMAP SEARCH ANNOTATE command to list all messages with some specific "bug=yes" type of annotation. For those messages then it can fetch the subject and whatever else metadata it wants. Newly created bugs don't have annotations though. To fix that, the BTS also uses ANNOTATEMORE (or is it METADATA nowadays?) extension to keep "last seen message in BTS" state in the mailbox's annotations. It then issues a SEARCH SUBJECT "[bug #" command for the new messages and does THREAD command for them to see if they're the bug root, or if they were replies to another message which should be treated as the bug root. When viewing a bug, the bug metadata comes from the annotations. Annotation history could also be kept, possibly as messages in another history mailbox. The messages for a bug can be viewed by issuing a THREAD (REFERENCES) command and showing all the mails that exist under the bug root. So, any volunteers to implement the web part, if I implement the ANNOTATE extension? :) It would actually even be possible to implement multiple frontends. All I need to do is give you access (read-only, or read-write for some) to the bug tracking mailbox, and you can use whatever frontend you wish, even a non-web one!

[Dovecot] Dovecot LDA issues
by Steven F Siirila 26 Mar '07

26 Mar '07

We've seen two issues come up with Dovecot LDA, both of which have caused us problems: 1) If the user's home directory does not exist, or is not owned by them, deliver fails and causes the mail message to bounce back to the originator. In our environment this happens when our user is moved to another server (where we move their files, but for up to 24 hours afterwards, continue to re-mail their /var/mail INBOX). This no longer works because the user has no home directory, causing deliver to fail with "Permission denied" when attempting to create their home directory for the purposes of creating INBOX index files. 2) If the user is over quota (in their home directory), deliver fails with a temporary error, causing requeues until the user is back under quota (which in our environment could be a long time, days). Since we've never had quotas on the user's INBOX (in /var/mail), this is a problem for us. I'd propose for both of these cases that deliver issue WARNING messages to its logs, and simply not create index files for the INBOX. If the INBOX index files already exist, and the user is over quota in /home, neither deliver nor any other Dovecot process should attempt to update them, and instead issue WARNING messages. This allows the e-mail to be delivered instead of requeued, or worse yet, rejected. Index files are supposed to make things perform better, not worse, in ALL cases. :) -- Steven F.

[Dovecot] deliver: -m, sieve and -n
by Jim Horner 26 Mar '07

26 Mar '07

Hi, I took a stab at editing the wiki ... the changes disappeared? I guess I was overruled. The wiki (http://wiki.dovecot.org/LDA) states -m <mailbox>: Destination mailbox (default is INBOX). If the mailbox doesn't exist, it's created (unless -n is used). If message couldn't be saved to the mailbox for any reason, it's delivered to INBOX instead. I tried to add a little note that the sieve plugin takes precedence. For example if at the end of the a .dovecot.sieve there is a line like: fileinto "CompanyFolders.general"; then the -m <mailbox> is ignored. I am not sure about the use of 'stop'. -n: If the destination mailbox doesn't exist, don't create it. This affects both -m parameter and fileinfo action in Sieve scripts. The fallback is to deliver mail to INBOX. (typo: fileinto not fileinfo) My testing shows that if the mailbox does not exist then the mail is rejected like so: === Your message was automatically rejected by Dovecot Mail Delivery Agent. The following reason was given: Mailbox doesn't exist: mail-lists.debian === I like the wiki's solution better. Jim

[Dovecot] dovecot authentication & exim in rc27
by Richard P. Welty 26 Mar '07

26 Mar '07

[introduction: new to the list, used dovecot w/exim as MTA in simple ways for 2 years, blah blah blah] i'm trying to get exim to use dovecot auth with a copy of rc27 and am missing something that's probably quite simple. specifically, how does one configure the authenticators in dovecot.conf for rc27? the auth section of the default config file installed in rc27 doesn't entirely look like what i'm seeing in other documentation; instead of auth default { } i'm seeing auth = default followed by lots of standard flags prefixed by auth_, but i don't see how to set up the socket. i have the following; dovecot starts and doesn't complain but it doesn't create the socket either: auth_socket listen { client { path = /var/run/dovecot/auth-client mode = 0660 user = exim group = exim } } any suggestions? thanks, richard

[Dovecot] anonymous mailing list archive configuration?
by Johannes Berg 25 Mar '07

25 Mar '07

Hi, I'd like to run a mailing list archive via IMAP like for this list but my mails are in maildir and not mbox. It's easy to add a new user that has access to the maildir that mails get stored in, and I can simply link that up to that user's inbox. It's also easy to prevent putting mail into that folder. However, one thing I'm not clear on is how to prevent that user from creating new folders. I don't think I can do that with permissions to the ~/Maildir since that user needs to be able to create files there for indizes etc. Is that possible? Should/can I write a plugin that prevents things? johannes

[Dovecot] 1.0.rc28 / v1.0 plans
by Timo Sirainen 24 Mar '07

24 Mar '07

I'll probably release 1.0.rc28 in a few days. Would be nice to get some testing for it first. http://dovecot.org/nightly/dovecot-latest.tar.gz contains pretty much what it's supposed to be. I've now replied to all the mails I was planning on replying, excluding the few patches that are v1.1 material. If you think I forgot to reply to some mail, please resend it. I think the documentation in Wiki is finally beginning to look pretty good. All the important things are done. The only things in my "would be nice TODO" list are: - Add a new page about index files and their configuration. I'll probably do this before rc28. - PasswordSchemes and Authentication/Mechanisms are pretty heavy reading. Could be made easier to understand. Possibly also create some mechanism-specific pages describing how to configure them in Dovecot and in clients. - Design documents would also be nice, but not very useful for non-programmers and pretty big job to write them I'm planning on adding the Wiki pages to doc/wiki/ in the tarball and changing: - http://wiki.dovecot.org/* links to doc/wiki/*.txt in dovecot-example.conf - doc/variables.txt could be removed and links to it updated to doc/wiki/Variables.txt - doc/auth-protocol.txt is also already in wiki. Maybe create doc/design/ and put the AuthProtocol.txt there and other design wiki pages there as well. As for v1.0, it looks like there aren't many bug reports anymore about rc27. If there are as few for rc28, I'll release v1.0 in about a month. So unless something special happens, I'll fix only the simplest bugs after rc28 and leave the rest to v1.1/v1.0.1. Hmm. Looks like 13.4. is Friday. Perhaps that's a good day for a release. :) Looks like I ended up adding a few more new features to rc28: * deliver + userdb static: Verify the user's existence from passdb, unless allow_all_users=yes * dovecot --exec-mail: Log to configured log files instead of stderr + When copying/syncing a lot of mails, send "* OK Hang in there" replies to client every 15 seconds so it doesn't just timeout the connection. + Added idxview and logview utilities to examine Dovecot's index files + passdb passwd and shadow support blocking=yes setting now also + mbox: If mbox file changes unexpectedly while we're writing to it, log an error. + deliver: Ignore -m "" parameter to make calling it easier. + deliver: Added new -n parameter to disable autocreating mailboxes. It affects both -m parameter and Sieve plugin's fileinto action - auth cache: If unknown user was found from cache, we didn't properly return "unknown user" status, which could have caused problems in deliver. - Index view syncing fixes - rc27 didn't compile with some non-GCC compilers - vpopmail support didn't compile in rc27 - NFS check with chrooting broke home direcotry for the first login - deliver: If user lookup returned "unknown user", it logged "BUG: Unexpected input" - convert plugin didn't convert INBOX

[Dovecot] Dovecot LDA Logging

I have Dovecot LDA logging fine right now but I really don't like having my log files world writable because I have users with shell access.

[Dovecot] multiple instances of dovecot on one machine
by Marshal Newrock 23 Mar '07

23 Mar '07

I was trying to run two instances of dovecot on the same machine, each listening on a single IP. The problem I ran into was that each time one was started or restarted, the other stopped responding. I saw the following in the logs: Mar 23 00:02:27 sentinel dovecot: Dovecot v1.0.rc27 starting up Mar 23 00:02:27 sentinel dovecot: Socket already exists: /var/run/dovecot/dict-server After I saw that, I commented out the dict section and quota from the plugins. The second line disappeared, but I could still only get one dovecot listening at a time. In the end, I went back to a single dovecot listening on all IP's, and found another way to do what I was trying to do, so all is still working for me. I'm guessing I'm the first person to try to run two dovecots on one machine. Actually, I should clarify: there was also a third, listening to none on localhost, but there only for the lda process. The auth socket was set to /var/run/dovecot/auth-master. And this also was not accepting connections while the others were running. -- Marshal Newrock Ideal Solution, LLC - http://www.idealso.com

[Dovecot] Possible bug with removing e-mail when user over fs quota
by Qweb - Yavuz Aydin 23 Mar '07

23 Mar '07

Dear list, I don't know if this is by design or possibly a bug, but there is a difference when removing e-mail when a user is over filesystem quota when indexing is on or off. All is working fine on our servers when indexing is on, users can remove then purge e-mail when over quota, but when we turn off indexing (by setting INDEX=MEMORY) it doesn't work. Users can remove, but not purge. And after a reload of the page the e-mail is there again. We are using Dovecot 1.0.rc15 on Debian Sarge (through backports.org) with mboxes. We have set up the configuration of dovecot regarding quota's according to http://wiki.dovecot.org/Quota/FS Unfortunately I don't have time to try this on the latest version, but is there anyone out there willing to try? -- Best regards, Yavuz Aydin Qweb Internet Services

[Dovecot] maildirsize problem?
by Alan Mosca [Aluminati] 23 Mar '07

23 Mar '07

Hello all, Recently I have received a few complaints from users that their quota was being reported wrong. This seems to have started when I switched to quota=maildir and ignore=Trash (did both at the same time). The main reported problem is that maildirsize is not correctly updated when they delete messages. My personal hypothesis is something like this: - User moves to Trash - Trash is ignored so it is not marked on the maildirsize (?) - User purges trash - Trash is still ignored so it is still not marked (?) Resulting in a buildup of errors in the maildirsize file. Would it be a good idea to mark the maildirsize file when a file is moved to an ignored folder? That could though potentially lead to people just moving to trash instead of deleting. Thank you guys and keep up the good work! -- Alan Mosca Systems Administrator Aluminati Network Group

[Dovecot] Timeout while logging in

Re: [Dovecot] deliver to subfolder with dovecot's LDA

[Dovecot] I wrote a managesieve server for Dovecot
by Neale Pickett 22 Mar '07

22 Mar '07

I have written a managesieve server from scratch in Python. I did just enough work to get it working with avelsieve (the squirrelmail plugin), smartsieve, and KDE's sieve kioplugin. It supports the entire Internet draft. Since I didn't have a working sieve server to compare against, I'm not sure if it's 100% compatible with timsieved. Client applications seem to work okay anyway. I wrote it in such a way as to decouple how authentication is carried out and how sieve scripts are actually stored, so you could for instance modify this to work with SASL and Exim. Currently it only has code for PAM and Dovecot's LDA, because I run Postfix :). TLS support is in the code but disabled because I had problems writing a unit test for it. All my connections are from localhost anyway. http://woozle.org/~neale/repos/pysieved if anyone is interested. I haven't looked closely at Stephan Bosch's managesieve server in C but I do want to acknowledge that he has written a C managesieve server that currently exists as a patch to the Dovecot source code. People looking for a managesieve implementation in C are encouraged to try his patch out: http://sinas.rename-it.nl/~sirius/ Neale

[Dovecot] tilde in mbox:, when used in non-system user db
by Michal Soltys 22 Mar '07

22 Mar '07

Originally I've thought that this is related to INBOX field, but it turned out it happens only when you specify mbox. Consider following passwd-file: testms::10000:10000:imap,,,:/home/vmail/ppgk.com.pl/testms/./::userdb_mail=mbox:~/Mail:INBOX=/home/vmail/ppgk.com.pl/%u/inbox or following line from userdb static: args = uid=10000 gid=10000 home=/home/vmail/ppgk.com.pl/%u/./ mail=mbox:~/Mail:INBOX=/home/vmail/ppgk.com.pl/%u/inbox In both cases, in user's directory, there will be an empty ~/Mail directory created, in addition to Mail and inbox. No idea about how sql or ldap would behave here, but global mail_location from dovecot.conf doesn't suffer from this issue (~ was expanded properly in ktrace dump). Chroot specification (/./) doesn't matter here. If I change mbox:~/Mail:INBOX=..... to mbox:/home/vmail/ppgk.com.pl/%u/Mail:INBOX=~/inbox then everything will be fine - no extra '~' dir. Thus my assumption it's not INBOX field related. Looking at ktrace, it seems that imap process is checking for the existence of ~/Mail, without expanding tilde. Then quite a bit later, it creates Mail as a "side effect" of creating Trash subdirectory. Relevant fragments: 1853 imap CALL mkdir(0x8a79b100,0x1f8) 1853 imap NAMI "~/Mail" 1853 imap RET mkdir -1 errno 2 No such file or directory 1853 imap CALL sigprocmask(0x1,0xffffffff) 1853 imap RET sigprocmask 0 1853 imap CALL mprotect(0x3c0ec000,0x1000,0x3) 1853 imap RET mprotect 0 1853 imap CALL mprotect(0x3c0ec000,0x1000,0x1) 1853 imap RET mprotect 0 1853 imap CALL sigprocmask(0x3,0) 1853 imap RET sigprocmask -65793/0xfffefeff 1853 imap CALL mkdir(0x8a79b108,0x1f8) 1853 imap NAMI "~" 1853 imap RET mkdir 0 1853 imap CALL mkdir(0x8a79b100,0x1f8) 1853 imap NAMI "~/Mail" 1853 imap RET mkdir 0 and 1853 imap CALL stat(0x8a79b180,0xcfbeb5c0) 1853 imap NAMI "/home/vmail/ppgk.com.pl/testms/Mail/Trash" 1853 imap RET stat -1 errno 2 No such file or directory 1853 imap CALL stat(0x8a79b1b0,0xcfbeb600) 1853 imap NAMI "/home/vmail/ppgk.com.pl/testms/Mail/Trash" 1853 imap RET stat -1 errno 2 No such file or directory 1853 imap CALL mkdir(0x8a79b1e0,0x1f8) 1853 imap NAMI "/home/vmail/ppgk.com.pl/testms/Mail" 1853 imap RET mkdir 0 1853 imap CALL open(0x8a79b1b0,0xa02,0x1b0) 1853 imap NAMI "/home/vmail/ppgk.com.pl/testms/Mail/Trash" 1853 imap RET open 7 My configuration is prtty much the same as previously: openbsd 3.9, i386, dovecot 1.0-rc27 (latest nightly, but the same happened in stock 1.0rc27) dovecot.userdb: testms::10000:10000:imap,,,:/home/vmail/ppgk.com.pl/testms/./::userdb_mail=mbox:~/Mail:INBOX=/home/vmail/ppgk.com.pl/%u/inbox dovecot.passdb: testms:{PLAIN}test: base_dir: /var/dovecot/ protocols: imap imaps pop3 pop3s ssl_listen: * ssl_ca_file: /etc/ssl/cert_bundle.pem ssl_cert_file: /etc/ssl/ca_ppgk/certs/fetch_crt.pem ssl_key_file: /etc/ssl/ca_ppgk/private/fetch_key.pem verbose_ssl: yes login_dir: /var/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login login_greeting: Dovecot IMAP server ready. login_greeting_capability(default): yes login_greeting_capability(imap): yes login_greeting_capability(pop3): no valid_chroot_dirs: /var/mail:/home/regular:/home/vmail verbose_proctitle: yes first_valid_uid: 1999 first_valid_gid: 10 mail_location: mbox:~/Mail:INBOX=/var/mail/%u mail_debug: yes fsync_disable: yes lock_method: fcntl maildir_copy_with_hardlinks: yes mbox_read_locks: fcntl mbox_write_locks: fcntl mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 imap_client_workarounds(default): outlook-idle delay-newmail imap_client_workarounds(imap): outlook-idle delay-newmail imap_client_workarounds(pop3): outlook-idle pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: mechanisms: plain login verbose: yes debug: yes passdb: driver: passwd-file args: /etc/dovecot.passdb passdb: driver: bsdauth userdb: driver: passwd-file args: /etc/dovecot.userdb userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master:

It is posible in the paper, in the real world? Hi Oliver, We run sendmail + dovecot on FreeBSD for around 3500 users. It runs smooth. We also run two other FreeBSD machines with Sophos PureMessage for Anti-SPAM and Anti-Virus cleanup which is linked via sendmail's milter. You're going to need Procmail to link sendmail and dovecot for local mail delivery to the user's mbox or Maildir, which ever you prefer. We're using Maildir here to serve both IMAP over SSL and POP3 over SSL. If you need any help in the setup of sendmail + procmail + dovecot, just tell me. Of course, if you're more experienced with Postfix, then use it. IMHO it's not as flexible as sendmail. But YMMV.

[Dovecot] GSSAPI authentication behind HA servers
by Mustafa A. Hashmi 22 Mar '07

22 Mar '07

Hi all, We have 2 mail servers sitting behind linux-HA machines.The mail servers are currently running dovecot 1.0rc2. Looking to enable GSSAPI authentication, I exported krb keytabs for imap/node01.domain@REALM and imap/node02.domain@REALM for both mail servers. However, clients are connecting to mail.domain.com, which results in a mismatch as far as the keytab is concerned (and rightly so). Connections directly to node01 and node02 work fine for gssapi auth. I proceeded to export a key for mail.domain.com into the same keytab for both the nodes, however, I don't think more than a single key is checked for the imap service, and authentication errors continued. Is anybody running something similar? Could you please explain how you have this working on your end? Appreciate any help. Regards, -- Mustafa A. Hashmi mahashmi(a)gmail.com

Greetings - I'm finalising the layout of our new mailstore ready for a trial service using Dovecot (switching from the UW IMAP server). This is using Maildir mailboxes, changing from our current mix of MBX and traditional Berkeley. One of the things we are often asked for is how someone can grant another access to their mailbox: eg, a Head of Department wants the Departmental Secretary to review and reply to e-mails, but not tell her the password. I understand that Dovecot doesn't provide a user-interface for setting up or manipulating these, nor the IMAP ACL extension at this time, so... Q1. Are there plans to add support for ACLs in the future, along with an end-user accessible means of setting these up and manipulating them? I also understand that it is currently possible for the Mail Admin to set up ACLs (globally and/or per-mailbox) and shared folders (I admit I'm having trouble getting my head around the latter in the Wiki a bit). I' hoping to avoid using the current "has to be done by the Administrator" setup, and instead want to plan for any future end- user interface. We are using filestore quotas for the Maildirs, so at present a user's Maildir directories and files are owned by their username (UNIX uid) and group (UNIX gid). * Naturally for filestore quotas to continue to work items need to continue to be owned by the person's username (UNIX uid). When end-user support for shared mailboxes and ACLs comes along one day (hopefully!) I assume two levels of access control are needed: 1. At the filestore level the other authorised users will need read and/or write access to the directories and files comprising the Maildir, and 2. Suitable ACLs will be needed to grant access via Dovecot to authorised persons, but not to other random people. So looking to the future, I'm therefore thinking that instead of having each user's Maildir directories and files owned by their UNIX uid and gid I should instead have them owned by their UNIX uid and a common-to-everyone UNIX gid. Eg, drwxrwx--- user1:mail directoryname -rw-rw---- user1:mail filename I realise there is an element of risk here, as we would be relying on Dovecot's security to limit access so that only authorised users can access a given person's mailbox. Is this the right approach to adopt? Or is there a better way of (one day) enabling Person A to share their mailbox to Person B but not Person C? (We need a solution that is general and based on ACLs, not one that relies on our creating custom UNIX groups and assigning people's usernames to these.) I've read the Wiki pages on ACLs and Shared Folders, but am having trouble putting the information together in my mind to (one day) solve this particular requirement. Can anyone shed any light, please?

[Dovecot] corrupted transaction log error resulting in multiple deliveries
by Justin McAleer 22 Mar '07

22 Mar '07

I'm finally picking my dovecot project back up now, and after upgrading rc19 to rc27, I sent a test message to an existing account which resulted in log entries like these: Mar 16 08:45:37 node7 deliver(user(a)example.com): Corrupted transaction log file /var/indexes/example/com/u/us/user/.INBOX/dovecot.index.log: Append with UID 3, but next_uid = 15368 Mar 16 08:45:37 node7 deliver(user(a)example.com): msgid=<20070316124031.8F089D39A5(a)node7.neonova.net>: save failed to INBOX Mar 16 08:45:37 node7 postfix/pipe[29267]: 8F089D39A5: to=<user(a)example.com>, relay=dovecot, delay=306, delays=306/0.01/0/0.02, dsn=4.3.0, status=deferred (temporary failure) So, as you can see deliver has the problem and defers delivery. Is dovecot supposed to be able to recover from a corrupted log file on its own? It repeated this until I manually wiped out the index directory (didn't try just removing the log files first, sorry). The kicker is that deliver actually did save the message to the inbox every time, so multiple copies were delivered (every time I flushed the queue until it was actually fixed, a copy was delivered). I have my mail directories on an NFS mount, and indexes on localdisk, FYI.

[Dovecot] Throttling Logins
by Sean Kamath 22 Mar '07

22 Mar '07

Hi. Earlier today I was hit with 612 login attempts in 7 minutes. They ramped up slowly, too. :-) They quickly hit the file descriptor limit. And then a login server spawned and died so quickly that dovecot just died. My question is, is there a way to throttle the number of login connections? I'm doing it in my firewall now, but it would be nice to be able to say something like "max-login-attempts: X" before we blacklist the IP (for some configurable time). yeah, I know V4.2 :-) By the way, I *really* appreciate all the effort that's gone into Dovecot. Great work, everyone. Sean

[Dovecot] mail looping
by Steven F Siirila 22 Mar '07

22 Mar '07

We are running Postfix 2.3.3 and Dovecot 1.0-RC27 on a Solaris 10 server. We use the Dovecot LDA for local delivery. Problems arise with looping mail whenever a user's .forward contains a reference to themselves. This most frequently occurs when a user sets up a vacation since it then puts this in their .forward file: \username, "|/usr/bin/vacation username" The vacation program runs fine, and sends a notice back to the message originator, but when an attempt is made to deliver the message locally, it fails with: Mar 21 13:02:16 myhost.mydomain postfix/local[13373]: 3DF5A2C63: to=<systest(a)myhost.mydomain>, relay=local, delay=0.15, delays=0.12/0/0/0.03, dsn=5.4.6, status=bounced (mail forwarding loop for systest(a)myhost.mydomain) Any ideas? I hope it's something stupid I've overlooked...

[Dovecot] Timeouts connecting via POP3
by Don O'Neil 22 Mar '07

22 Mar '07

I'm experiencing timeouts from time to time from both Mac Mail and Outlook when connecting to my server. I originally suspected that it might be process # related, so I increased the auth & login process counts but that hasn't seemed to make a difference. I'm running 1.0rc10 which came with my DirectAdmin control panel. I'm wondering if this problem is known and was fixed in a later release? I'm waiting for instructions from the DirectAdmin folks on building a new version in case they do something special. Any ideas? Thanks!

[Dovecot] Solaris Dovecot dovecot dovecot-1.0.rc27
by Randall Svancara 22 Mar '07

22 Mar '07

To all, I am using Dovecot on solaris 10. Home directories are mounted using NFS. However, they are not readable by root. I compiled Dovecot from the source. I set the following environment variables: export LDFLAGS='-L/local/software/openssl/lib -R/local/software/openssl/lib' export CPPFLAGS=-I/local/software/openssl/include Then I ran gmake and the gmake install. In the server logs, when I attempt to connect to port 993 using imap over SSL, i receive the following error: dovecot: Mar 21 15:34:25 Info: imap-login: Login: user=<someusername>, method=PLAIN, rip=134.121.92.228, lip=134.121.5.141, TLS dovecot: Mar 21 15:34:25 Error: IMAP(someusername): ld.so.1: imap: fatal: libgcc_s.so.1: open failed: No such file or directory dovecot: Mar 21 15:34:25 Error: child 13085 (imap) killed with signal 9 Has anyone seen similar issues?

[Dovecot] Comments about LDA wiki page
by Magnus Holmgren 22 Mar '07

22 Mar '07

I've just tried out Dovecot LDA. The reason I didn't want to use it before was that I found it unnecessary together with Exim, plus I wanted to use Exim's filtering. But now I wanted to see if can notice any improvement when the indexes are updated on delivery, and I saw that it's possible to use Exim filters and pass the resulting folder with -m. Now, correct me if I'm wrong, but IIUC some corrections, improvements, and comments could be made on http://wiki.dovecot.org/LDA. In the "Site-wide setup" section (and in dovecot.conf) it's suggested that access be restricted to the master socket somehow. The first Exim example ("System-users"), however, requires a world-writable socket. Uncomment "group = mail" and deliver will complain that setgid() fails. In this situation, the "-d $local_part@$domain" is unnecessary because then deliver will use the name of the user it's running as (it should probably have been just "-d $local_part" anyway). However, if deliver is run by root (which is by default impossible under Exim) or setuid root, then a destination user is mandatory. Oh wait, without -d the auth socket isn't used at all, only the HOME environment variable and default_mail_env are. Well, it shouldn't matter much if you're running a standard pam/passwd setup, but with a more complicated non-virtual setup I see only four solutions: Make deliver setuid root, remove root from the compiled-in FIXED_NEVER_USERS list, run deliver as a user/group that has write access to all mailboxes, or make the master socket world-writable. -- Magnus Holmgren holmgren(a)lysator.liu.se (No Cc of list mail needed, thanks)

[Dovecot] How does vpopmail support works?
by Oliver Schulze L. 22 Mar '07

22 Mar '07

Hi, I'm still trying to migrate a running qmail + vpopmail to sendmail + dovecot. I need the milter stuff from sendmail. I got sendmail + dovecot running using the migrated tables from the vpopmail DB, but I'm facing the UID problem in pop3. So, now I'm following the vpopmail authdb path. My questions are: - what do I need, a running vpopmail server (lib + binary, etc)? - or only the DB? This is on Centos 4.4 Many thanks Oliver -- Oliver Schulze L. | Get my e-mail after a captcha in: Asuncion - Paraguay | http://tinymailto.com/oliver

[Dovecot] Wiki needs updating: Dovecot LDA + Dovecot Sieve + Exim
by Stephen Usher 22 Mar '07

22 Mar '07

So as to make sure that Dovecot Sieve's vacation system works Exim has to be forced to generate a "Reply-To:" header in the message (which it doesn't do by default). The current example for using the Dovecot LDA with Exim doesn't do this. Here is a replacement example for the local_delivery transport:- local_delivery: driver = pipe command = /usr/local/libexec/dovecot/deliver -d $local_part message_prefix = message_suffix = log_output delivery_date_add envelope_to_add return_path_add headers_add = Reply-To: ${if def:header_reply-to:{$h_reply-to:}{$h_from:}} #group = mail #mode = 0660 Basically, if the Reply-To: header exists than it merely gets overwritten with itself. If it doesn't then the header is created and the contents of the From header is put into it. If this is not done then the libsieve over restrictive rules (requiring a "Reply-To:" header even though the RFC doesn't require it) will not allow the vacation system to work.

[Dovecot] Doubled mails and UIDs
by Adam Lackorzynski 22 Mar '07

22 Mar '07

Hi, I'm still seeing mails being downloaded twice via POP3 in my setup, running rc27. The log file shows: dovecot: Mar 18 22:08:05 Error: POP3(joe): mbox sync: UID inserted in the middle of mailbox /home/joe/Mail/INBOX (442671 > 80, seq=10, idx_msgs=153) dovecot: Mar 18 22:08:05 Info: POP3(joe): Disconnected: Logged out top=0/0, retr=153/1069109, del=153/153, size=1066449 The next POP3 connect will fetch most of the messages again. dovecot: Mar 18 22:18:48 Info: POP3(joe): Disconnected: Logged out top=0/0, retr=147/1006204, del=147/147, size=1003647 Is there a problem if an incoming message already contains an X-UID header? Might it be worthwhile to remove this header when mails are being delivered (e.g. with procmail)? Thanks, Adam -- Adam adam(a)os.inf.tu-dresden.de Lackorzynski http://os.inf.tu-dresden.de/~adam/

[Dovecot] rc27 assert, mbox format

Timo, After several days of flawless work, rc27 gave an assert/core yesterday: Mar 19 00:10:46 karst dovecot: [ID 107833 mail.error] IMAP(user): file mbox-sync-rewrite.c: line 423: assertion failed: (need_space == (uoff_t)-mails[idx].space) Mar 19 00:10:46 karst dovecot: [ID 107833 mail.error] IMAP(user): Raw backtrace: 0x8a51c -> 0x473f4 -> 0x479b0 -> 0x41c50 -> 0x42430 -> 0x431d4 -> 0x43dac -> 0x44040 -> 0x2aa70 -> 0x2afec -> 0x2337c -> 0x23508 -> 0x235f0 -> 0x90c18 -> 0x9043c -> 0x2cfac -> 0x1dbe8 I could see nothing wrong with the user's mailbox, it was not corrupted. My setup: Solaris 10 sparc, mbox format, INBOX NFSv4 mounted from another S10 sparc system, no disk quotas, ZFS filesystem for both the INBOX filesystem and the user's home directory. Unfortunately, I compiled dovecot with Sun's cc compiler, so the gdb traceback is fairly useless. I need to go back to gcc. Jeff Earickson Colby College

[Dovecot] Double homedirs and tilde problems in case of chroot in passwd-file / static dbs.
by Michal Soltys 21 Mar '07

21 Mar '07

Recently I've made the post about "double homedir" problem, but I couldn't recreate it later. Here're the exact steps to make it happen (configuration is at the bottom): 1) set configuration as below with passwd-files 2) clean testms dir (not necessary though) 3) reload dovecot (HUP is enough) 4) access the server with any client using testms user (make sure no other user accesses server before you) - on the first access, dovecot will create /home/vmail/ppgk.com.pl/testms/Maildir under /home/vmail/ppgk.com.pl/testms/ - on every next access, dovecot will access (and create if it doesn't exist) proper Maildir under "single" home path Situation will repeat itself, if dovecot is reloaded (or killed and restarted). It happens to both imap and pop3. Note, that the a single access seems to be enough to "fix" the problem to all the other users in passwd-file, should there be any. The problem seems to be created by chroot specification in passwd-file & static (and possibly when other dbs are used). On the first access, dovecot attempts to recreate whole /home/vmail.... directory structure *after* chrooting to the homedir (or without taking earlier chroot into account), at least that's how it looks from ktrace. If I moved /./ to the left by one subdir, dovecot would attempt to do it under root owned /home/vmail/ppgk.com.pl/ and fail in the process. And so on. Tilde is another problem - if in dovecot.userdb I change - maildir:~/Maildir: to mbox:~/Mail:INBOX=~/inbox: - then single '~' directory will be created under /home/vmail/ppgk.com.pl/testms/, along the inbox file and Mail dir. If INBOX, CONTROL and/or INDEX is specified explicitely in maildir case, '~' won't be created. That leads to the questiom - is tilde allowed in INBOX under mbox storage at all ? I can't check '~' in INBOX/mbox case for system accounts atm though. If you need any more info (like ktrace), let me know.

[Dovecot] Index files in .imap directory
by Steven F Siirila 21 Mar '07

21 Mar '07

A few RC releases ago we had a problem where a user's restored home directory contained a .imap folder either from a previous RC release or perhaps it was a different server. In any event, restoration of the user caused problems since Dovecot choked on the restored .imap index files. Removing those index files cleared the problem. I'm wondering if this is still an issue, and therefore whether we need to find and remove all .imap folders prior to archiving users, so that they are not restored with potentially old/bad index files. I would like to NOT have to worry about them, but rather have Dovecot be smart about when to simply re-create them if it detects something it does not like about them. -- Steven F.

Hi Timo, What I did actually was change option (D) to the following below, or do I have to remove this one altogether? plugin { quota = maildir } Then added the attribute mailquota=10240 as I had defined in my dovecot schema And when I did a tried to run getquota "" or getquotaroot inbox (via telnet localhost 143), it would return me a "no quota" message. What I am able deduce is that the mailquota attribute did not take effect at all. Do you think I may have missed something out. And thanks for your prompt reply, really appreciate it.

Even after I've added the attribute mailquota in the ldap for the entry uid=ldapuser it still does not look like its taking any effect at all. Regards and thanks in advance.
