[Dovecot] Connection refused with auth-master after upgrading to Dovecot 1.0 rc 28
by Jason Warner 12 Apr '07

12 Apr '07

Fedora pushed out an update to Dovecot 1.0 rc 28 today. After upgrading, mail isn't delivered to local recipients. My log file is full of error messages similar to the following: Apr 2 12:56:32 mail deliver(user(a)domain.com): net_connect(/var/run/dovecot/auth-master) failed: Connection refused I'm including some snippets from my dovecot.conf file that pertain to the auth-master file: protocol lda { # Address to use when sending rejection mails. postmaster_address = postmaster(a)brashers.com mail = maildir:/home/vmail/mail/%n # Hostname to use in various parts of sent mails, eg. in Message-Id. # Default is the system's real hostname. #hostname = # Support for dynamically loadable plugins. mail_plugins is a space separated # list of plugins to load. #mail_plugins = #mail_plugin_dir = /usr/lib/dovecot/lda mail_plugins = cmusieve mail_plugin_dir = /usr/lib/dovecot/lda # Binary to use for sending mails. #sendmail_path = /usr/lib/sendmail # UNIX socket path to master authentication server to find users. auth_socket_path = /var/run/dovecot/auth-master #auth_socket_path = /home/vmail/mail/auth-master } socket listen { master { # Master socket provides access to userdb information.

Any help would be greatly appreciated.

[Dovecot] Dovecot deliver agent - dovecot.conf permissions
by Daniel L. Miller 12 Apr '07

12 Apr '07

I started playing with deliver, and saw a permission error in the logs for dovecot.conf. Under my distro install, /etc/dovecot.conf was installed owner/group root, with only user rw rights. I added "other" read privileges and deliver is happy - is this necessary? -- Daniel

[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] [PATCH] Compile cleaning against OpenLDAP 2.3.x
by Roy Marples 12 Apr '07

12 Apr '07

Hi List Looks like OpenLDAP 2.3 doesn't define LDAP_DEPRECATED [1] anymore which causes a few warnings in Gentoo [2]. Attached is a patch that re-defines this so that dovecot can continue using simple functions like ldap_bind().

[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

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

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

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.

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

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
by Stewart Dean 10 Apr '07

10 Apr '07

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
