Hello, I'm attempting to migrate from an existing dovecot .99 install to dovecot 1.0.rc15 on a fresh up to date CentOs 5.1.

[Dovecot] Postfix, mailbox_command, Dovecot deliver, LDAP and mail_location
by Patrick Ben Koetter 02 Feb '08

02 Feb '08

I am trying to tell Dovecot deliver to use $mail_location as the location to store mail for system users. From the docs I've read <http://wiki.dovecot.org/MailLocation> I believe this is possible, but mail to my system users always gets delivered to their /home/<USERNAME> homedirectory. Here's what I've done so far: # Postfix main.cf mailbox_command = /usr/lib/dovecot/deliver # Dovecot # dovecot-ldap.conf user_attrs = mailHomeDirectory=home,mailUidNumber=uid,mailGidNumber=gid,mailQuota=quota=maildir:storage,mail=mailHomeDirectory Above you can see, I query for $mail as documented in <http://wiki.dovecot.org/UserDatabase>. # dovecot.conf # dovecot -n # 1.0.5: /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s ssl_cert_file: /etc/ssl/mail.state-of-mind.de.crt ssl_key_file: /etc/ssl/private/mail.state-of-mind.de.key disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login login_greeting_capability(default): yes login_greeting_capability(imap): yes login_greeting_capability(pop3): no mail_extra_groups: mail mail_location: maildir:~ mail_debug: yes maildir_copy_with_hardlinks: yes mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 imap_client_workarounds(default): outlook-idle netscape-eoh delay-newmail imap_client_workarounds(imap): outlook-idle netscape-eoh 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 digest-md5 cram-md5 ntlm passdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf userdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf socket: type: listen master: path: /var/run/dovecot/auth-master mode: 384 user: virtual group: virtual What am I missing?

[Dovecot] Bug handling zero-byte files in maildirs

[Dovecot] Dovecot, LDAP and something akin to Postfix' "table search order" from virtual deliver.
by Pawel Sawicki 01 Feb '08

01 Feb '08

Hi. /* The short version. */ Is there a way to mimic Postfix' "table search order" in Dovecot's LDAP configuration of pass_filter/user_filter? /* Here goes the detailed description :) */ Just to quote the http://www.postfix.org/virtual.8.html: --- TABLE SEARCH ORDER (...) The search order is as follows. The search stops upon the first successful lookup. (...) o The user(a)domain.tld address, without address exten- sion, is looked up next. o Finally, the recipient @domain is looked up. --- Basicaly this allows to have separate users assigned addresses like j.doe(a)example.com (first account), j.smith(a)example.com (second account) and at the same time to have a "catch all" anything(a)example.com mailbox (for the administrator e.g.). What do I need it for? To have dovecot-lda working. Why? I want Sieve :) The test data may look as follows: account #1: + mail: j.doe(a)example.com + mailAlternateAddress: j.c.doe(a)example.com account #2: + mail: j.smith(a)example.com + mailAlternateAddress: j.t.smith(a)example.com account #3 (administrator): + mail: bofh(a)example.com + mailAlternateAddress: @example.com (means - anything possible) The filter I used is (more or less - for both pass_filter and user_filter): (|(mail=%u)(mailAlternateAddress=%u)(mailAlternateAddress=@%d)) Just for testing purposes I've stripped off some irrelevant data (like checking if the account is active), since that made the filter about 140 characters long ;) The trouble is when there're both a "catch all" and a true account that are linked to different accounts. As an example, if I try to send mail to "j.doe(a)example.com" I receive: dovecot: auth(default): ldap(j.doe(a)example.com): Multiple replies found for user Which is of course true, since the filter returns "account #2" and "account #3". What I'd like to get? I'd like to set the filter to: (|(mail=%u)(mailAlternateAddress=%u)) Where "%u" is expanded to "j.doe(a)example.com" during the first run Then, if dovecot can't find any user that would match this literaly it should retry the search operation, but now with "@example.com" as the "%u". I've tried to fiddle with the filter itself, but I see any reasonable way of doing it. I don't even know if it is possible at all. Could anyone give me a hint? Or maybe it's already on someone's whish list? Some final info. * I've followed the examples on dovecot.org website: http://wiki.dovecot.org/LDA#head-dacb9b9a1f19c3ea86bb6f8caa3d64e3ddad9ef8 * Here's the dovecot's master.conf entry: dovecot unix - n n - - pipe flags=DRhu user=mail:mail argv=/usr/libexec/dovecot/deliver -d ${recipient} Best regards!

[Dovecot] Gnus and dovecot time out
by Richard G Riley 31 Jan '08

31 Jan '08

Could someone suggest what the solution here is? Dovecot is terminating the connection to Gnus after a certain period of activity. It's my own mail server so no need to worry about "hogging resources". Should/could Dovecot be configured to keep the connection alive, or should Gnus be programmed to automatically reopen the conneection? The current problem that one can not leave an IMAP group if the connection is cut by the server. Here is the text posted and replied to on the gnus usenet: ,---- | I have the same problem as the article I link and reproduce below. Is | there a way to get Gnus to keep an IMAP session open without using a | daemon to check for all new messages regularly? | | http://osdir.com/ml/emacs.gnus.user/2006-02/msg00133.html | | ,---- | | Subject: Gnus closing imap connection | | List-id: "Announcements and discussions for GNUS, the GNU Emacs Usenet newsreader $in English$" <info-gnus-english.gnu.org> | | | | My IMAP connection closes and Gnus does not reopen it.

[Dovecot] Multiple copies of a message
by Anne Wilson 31 Jan '08

31 Jan '08

I have a problem and I don't know which part of the mail chain could be causing it, although dovecot does seem to be the most logical source. I get multiple copies of messages to my Inbox. I have just deleted 24 copies of a newsletter from Computer Shopper. The worst example I have seen of this had more than 90 copies. This doesn't happen to any subfolder of Inbox, just Inbox itself. The problem started about 10-14 days ago, on the old mail server (running Mandriva 2007.1). The new server runs CentOS and exhibits the same problem. I'd be interested in any comments, as my efforts to track it down have got nowhere. Anne

[Dovecot] Rename file opened for read-write -- cannot edit subscriptions
by Jack Schmidt 31 Jan '08

31 Jan '08

Howdy, Here is a problem with fix affecting dovecot-1.0.10 (and 1.1rc13). On a linux system's CIFS mounted filesystem, it is not possible to rename a file opened read-write: $ sleep 5 >> .subscriptions.lock & mv .subscriptions.lock .subscriptions mv: cannot move `.subscriptions.lock' to `.subscriptions': Text file busy This causes problems in editing subscriptions, as the new subscription list is still open for writing before it is renamed in: lib-storage/subscription-file/subscription-file.c line 169 in dovecot version 1.0.10 (and 1.1rc13) This is an unpatched linux 2.6.21-5, CIFS mounted filesystem from a windows 2003 sp2 server. The documentation for rename(2) indicates that it is allowed to return an error when the file is already opened, so perhaps the file should be closed before the replace. Should this be done in file_dotlock_replace (before line 672) generally? Here is a patch that does so: diff -rw -U3 dovecot-1.0.10/src/lib/file-dotlock.c dovecot-1.0.10-patch/src/lib/file-dotlock.c --- dovecot-1.0.10/src/lib/file-dotlock.c 2007-12-11 13:52:08.000000000 -0500 +++ dovecot-1.0.10/src/lib/file-dotlock.c 2008-01-23 08:53:33.000000000 -0500 @@ -635,7 +635,7 @@ struct dotlock *dotlock; struct stat st, st2; const char *lock_path; - int fd; + int fd, old_errno; dotlock = *dotlock_p; *dotlock_p = NULL; @@ -669,6 +669,14 @@ } } + if (dotlock->fd != -1) { + old_errno = errno; + if (close(dotlock->fd) < 0) + i_error("close(%s) failed: %m", dotlock->path); + dotlock->fd = -1; + errno = old_errno; + } + if (rename(lock_path, dotlock->path) < 0) { i_error("rename(%s, %s) failed: %m", lock_path, dotlock->path); file_dotlock_free(dotlock);

[Dovecot] Using Dovecot with nsswitch for LDAP on Solaris
by Laurent Blume 31 Jan '08

31 Jan '08

Hello all, I'm having some issues configuring dovecot 1.0.10 on a Solaris 10 box, that uses LDAP¨for its accounts. The local accounts (in /etc/passwd) are authenticated properly and work as expected, but all accounts from the LDAP fail authentication. Those are declared for the system using PAM and NSS (/etc/pam.conf and /etc/nsswitch.conf are configured accordingly). Currently, there are WU-IMAP and Qpopper installed and working, and neither of them needed any special configuration to use the login, they're just using Unix auth. I tried various configurations, based on what I read in the wiki documentation, but nothing works, even the passwd userdb/passdb, which *should* if I understand correctly. Trying to use PAM in dovecot fails, too. Any idea what I'm doing wrong, or pointers to hints? Google returned little information about configuring Dovecot on Solaris, and none that was useful.

[Dovecot] Using dovecot proxy as multi-account aggregator?
by Mika Boström 31 Jan '08

31 Jan '08

Good day. I am trying to build a rather weird setup. The basic idea is to have a relatively simple IMAP client and let dovecot do the actual connections. So far both the documentation and my trials on this front have been rather fruitless. The desired components: - 1 dovecot server, acting as a proxy - 1 master account - 1 client connection - 0 "real" user accounts, so no local mail storage at all - N real accounts, spread over different domains - mails from different remote accounts combined to the single client connection - outgoing server for mails selected by the address of the remote account Since the proxy setup can use name(a)domain.tld as destination user, it would appear that the setup is not impossible. Hence my two questions: 1) Is it possible? 2) If yes, how in the name of all that is good and holy do I configure that? And believe me, I am fully aware that for most setups a full-featured client or fetchmail would be the easier path. Thank you for any and all help in advance, -- Mika Boström / mika.bostrom(a)nomovok.com

[Dovecot] Dovecot + Windows AD + Postfix + quota
by Maciej Paczesny 31 Jan '08

31 Jan '08

Hello, I'm almost sure that all topics and problems mentioned below were separately posted to this list already. But after spending 4 days on searching, I did'n find a compilation similar to my case. So maybe some of you guys, are able to answer to help me solve this: 1. I'd like to use userdb and passdb of Dovetcot to work with Windows AD. 2. I have to use them both because I'd like to use LDA to serve for my Postfix. 3. I DO NOT want tou use any external programs (ie PAM) to talk to AD server. 4. I was able to make my system partially running - I CAN bind to AD database, and confirm user/password. 5. I want to get follownig attributes: home directory (OK, I could put it statically), uid/gid (OK, it could be static too) and MAIL QUOTA (my users have different values - no 'statics').

is it shown somewhere? how can it be verified? the value "storage=10240000000 " is a static one written in config and the same for all users. is there any kind of manual on how to make AD and Dovecot running and returning uid, gid, home, quota etc attributes without PAM?

[Dovecot] SQL user_query question
by John Dubchak 31 Jan '08

31 Jan '08

Hi, I am working through setting up a virtual hosting system using Dovecot, Postfix and Postgres on a CentOS 5 box running an install of the dovecot-1.0-1.2.rc15.el5 RPM. The question I have is, given this password_query SELECT clause, which all return valid values from the database: user password domain can I use a %d in the WHERE clause of my user_query? The reason I ask is that the log file shows the results coming back correctly for the password_query in the log file: dovecot: auth(default): client out: OK 1 user=user1 domain=domain.com Yet, the user_query that is logged shows: dovecot: auth(default): sql(user1,192.168.0.77): SELECT vu.virtual_mailbox AS home, vu.virtual_uid AS uid, vu.virtual_gid AS gid, vd.domain AS domain FROM virtual_users vu, virtual_mailbox_domains vd WHERE vu.domain_key = vd.id AND vu.username = 'user1' AND vd.domain = '' And the actual query in my dovecot-sql.conf looks like this: user_query = SELECT vu.virtual_mailbox AS home, vu.virtual_uid AS uid, vu.virtual_gid AS gid, vd.domain AS domain FROM virtual_users vu, virtual_mailbox_domains vd WHERE vu.domain_key = vd.id AND vu.username = '%u' AND vd.domain = '%d' I would have expected the above %d to contain the "domain" SELECT value from the password_query, but that doesn't seem to be the case. Any insight is most appreciated. Thanks, John

[Dovecot] multiple ports, different characteristics
by bill-dovecot＠carpenter.ORG 31 Jan '08

31 Jan '08

The wiki <http://wiki.dovecot.org/Iptables> leads me to believe that the only way to configure dovecot to listen for the same protocol on multiple ports is via external redirection (iptables or similar). Is that so, or can dovecot be directly configured to listen on multiple ports? Here's a concrete example of what I'm trying to accomplish. Our environment uses plaintext authentication, and so we force our users to use TLS for IMAP. For some internal connections (specifically with dovecot built-in proxying), we need non-TLS connections for IMAP. It's completely OK here if we need to listen on different ports for the two flavors of connections. Can dovecot be configured to handle this and/or do we need to run multiple instances of dovecot with different config files? Thanks -- bill-dovecot(a)carpenter.ORG (WJCarpenter) PGP 0x91865119 38 95 1B 69 C9 C6 3D 25 73 46 32 04 69 D6 ED F3

[Dovecot] Deliver a message marked as read.
by "Fábio M. Catunda" 31 Jan '08

31 Jan '08

Hi. Is there a way to deliver a message already marked as read. I would like to configure my MTA to deliver a copy of all sent messages to a folder named Sent in the user Maildir, I believe that it would be interesting to keep this folder always marked as readed. I'm not sure what define a message readed (a mark, a xheader or something) thats why I'm asking here! Any idea is apreciated. Thanks, Catunda.

hi, i've found this topic while looking for a solution for the way to use 'mail groups' with dovecot an postfix, using dovecot as LDA. i'm not sure if this patch is implemented into the source or not. or maybe there is a 'special' way to have multilpe mailboxes served by postfix/dovecot? -- Maciej Paczesny maciunio2(a)gmail.com ***Gdyby nie wymyślono elektryczności, siedziałbym przed kompem przy świeczkach***

[Dovecot] viewing a subset of folders in dumb IMAP clients
by Amitai Schlair 31 Jan '08

31 Jan '08

I have several dozen IMAP folders (stored as Maildir++). When I'm on the go with my iPhone, I only want to see a few of them. My naive solution that didn't work: 1) create an alternate login that yields my existing permissions and mail folder, but stores its own version of metadata 2) configure the iPhone to use that login 3) subscribe to the folders I want I test-drove the Dovecot config in a webmail app and it worked exactly right, but it turns out the iPhone (running the latest, 1.1.3) apparently doesn't respect IMAP subscriptions. My world-weary, clunkier, but seemingly working solution: 1) have the alternate login yield my existing permissions, but a different mail folder and metadata 2) create that mail folder, make its cur/new/tmp symlinks to the real ones, and symlink in the other folders I care about Is this safe? And is there a more elegant way to do what I want? Thanks, - Amitai

[Dovecot] Shared inbox
by adsarebad＠gmail.com 31 Jan '08

31 Jan '08

Hello all, I am using dovecot with maildir storage. I want to share a inbox of one user with another user. I read the page http://wiki.dovecot.org/SharedMailboxes but it does not deal with inboxes. I tried a test of a non-inbox folder and it worked great. The inbox does not have a .inbox folder instead its kindof spread through the root of the mailbox. Should I create a folder say .shared-inbox with a symbolic link to cur new tmp in other-guys-mail-folder? What about index files, uid list, and keywords? Thanks

[Dovecot] More efficient Deleting of a whole folder (or Purging Trash)
by Daniel Watts 31 Jan '08

31 Jan '08

Hi, I've straced a few dovecot processes after hitting purge on a large Trash folder (35,000 messages). It looks like it is going through each message, one by one, and removing (unlinking) each one. Is there not a more efficient way to do this? If Dovecot knows the whole folder is being deleted (ie a Trash purge), could it do something clever with the filesystem to just remove the whole folder? Incidently, the command that initially deleted those 35k messages to Trash took about 1 hour to complete on my server and effectively locked my account out for all that time. There were also an awlful lot of these output from my strace: nanosleep({0, 131475000}, NULL) = 0 lstat("/home/virtual/xxx.com/home/admin/Maildir/.Folders.Porter/dovecot-uidlist.lock", {st_mode=S_IFREG|0600, st_size=0, ...}) = 0 Not sure if there's much one can do about speeding up deleting a lot of messages though. My webmail client has a 'delete all messages' button for each folder. If there was an efficient IMAP command for deleting a whole folder that would be useful in those circumstances. Interested to know if there is anything that can be improved. Thanks, Daniel Dovecot 1.0.9 XFS Filesystem Maildir Directories

Can some one please help w/this? Additionally is there a way to run mail_convert on the command line to try to sort out the arguments? I noticed the converts are .so and .a in /usr/local/lib/dovecot/ so I doubt it but it can not hurt to ask.

[Dovecot] Virtual Alias Forwarding

I'm having a problem with Dovecot and forwarding of aliases. Any help would be greatly appreciated.

Mail gets to the correct mailbox (address field), however, if I change the destination mailbox (goto) in the alias table in mysql, the mail still goes to the main mailbox (address). mysql_virtual_alias_maps.cf looks to be configured correctly but I'm suspecting that dovecot is circumventing that file. I'll post maillog entry, dovecot-deliver.log entry, dovecot-mysql.conf, mysql_virtual_alias_maps.cf, and dovecot.conf below in case that helps. Thanks in advance for anything that helps me resolve this.

[Dovecot] sa learning from an imap spam folder
by Zbigniew Szalbot 29 Jan '08

29 Jan '08

Hello, I am sorry if I am writing to a wrong list because honestly I do not know where to write but I would like to be able to set up sa-learn via cron to learn from spam folder of a particular email account (via IMAP). Can anyone share how to do it? Is dovecot involved in it? I am using: Exim 4.69 Dovecot 1.0.10 p5-Mail-SpamAssassin-3.2.1 Thanks a lot for helping. Zbigniew Szalbot

[Dovecot] Load average on machine 400+
by Patrick 29 Jan '08

29 Jan '08

Hi all, Over the past week our mail server which NFS mounts the /home directory for mail has been experiencing major load issues. When doing a 'top', it appeared that slapd was the culprit (we use LDAP for authentication), but after upgrading the system and updating ldap, the cpu usage for LDAP has gone down, but the load average as not. I'm using Maildir. Everything from /home is NFS mounted, and the structure looks like this: /home/USERNAME/Maildir We're doing about 300 email messages a minute right now to that server, which isn't that much. I'm at a loss of words right now as I do not know where to troubleshoot from here. I've come up with the following questions: 1) I've noticed that some of our users have 500mb Maildir folders some even have 3gb+ - would this cause the CPU to have such a high load? 2) Currently on the box there is about 120 POP3 connections and 40 IMAP connections. Could this be the issue? 3) When I first set up this server, I appended INDEX=MEMORY to the end of the mail_location line. Should I remove this? I wanted to either remove it or put it on the local machine to speed things up. Here is my config: ##################### protocols = imap imaps pop3 pop3s listen = * disable_plaintext_auth = no log_path = /var/log/dovecot.log ssl_disable = no ssl_cert_file = /usr/share/ssl/xyz.com/xyz.com.crt ssl_key_file = /usr/share/ssl/xyz.com/xyz.com.key login_dir = /var/run/dovecot-login login_user = dovecot login_process_size = 64 login_process_per_connection = yes login_max_processes_count = 128 login_max_connections = 256 mail_location = maildir:/home/%u/Maildir:INDEX=MEMORY mmap_disable = yes fsync_disable = yes first_valid_uid = 200 maildir_copy_with_hardlinks = yes maildir_copy_preserve_filename = yes protocol imap { imap_client_workarounds = outlook-idle delay-newmail } protocol pop3 { pop3_no_flag_updates = no pop3_lock_session = no pop3_uidl_format = %08Xu%08Xv pop3_client_workarounds = } protocol lda { fsync_disable = no postmaster_address = postmaster(a)xyz.com hostname = mail.xyz.com } auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@ auth_username_format = %Lu auth_verbose = yes auth_worker_max_count = 30 auth default { mechanisms = plain login passdb pam { args = blocking=yes } userdb passwd { } user = dovecot-auth socket listen { client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } } dict { } plugin { } ##################### Again, this only happened within the past 1-2 weeks. How can I fix? Thanks in advance! Patrick

Re: [Dovecot] Dovecot/SeLinux issues after RHEL5.1 upgrade

Thanks to Marius, I've got this problem fixed! I don't know how or why, but selinux directory contexts have been altered during the update for everyone else on the system except myself (what makes it odd is that my user has the same group and permissions as everyone else). So what did the trick was to apply: chcon -t user_home_dir_t to each user's home, mail, .imap and INBOX directories. Thanks again for pointing me in the right direction, Marius!

[Dovecot] Messages not moved from Inbox by Apple Mail (Dovecot 1.0.10)
by Tom Collins 29 Jan '08

29 Jan '08

I just upgraded a server from Courier-IMAP to Dovecot, and I'm seeing some odd behavior. It's probably the result of something I did wrong in my configuration, and I'm hoping someone will let me know the easy fix for it. I have rules set up in Apple Mail to move and copy messages to different folders, some of which are IMAP folders, others on my own system. With Courier-IMAP, the messages would get moved without a problem. With dovecot, that's not happening. Here's my dovecot config. I've tried changing maildir_copy_with_hardlinks and maildir_copy_preserve_filename to "no", but that didn't seem to help. # 1.0.10: /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 verbose_proctitle: yes first_valid_uid: 89 last_valid_uid: 89 first_valid_gid: 89 last_valid_gid: 89 maildir_copy_with_hardlinks: yes maildir_copy_preserve_filename: yes namespace: type: private prefix: INBOX. inbox: yes auth default: mechanisms: plain login digest-md5 cram-md5 username_chars: abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@% username_translation: %@ passdb: driver: vpopmail userdb: driver: vpopmail plugin: quota: maildir I haven't tried logging the IMAP session yet, but I can turn off SSL, fire up Wireshark and monitor the session if necessary. Is this a known problem? I'm able to move messages between folders manually, but when Apple Mail moves the new messages it doesn't work. -- Tom Collins - tom(a)tomlogic.com Vpopmail - virtual domains for qmail: http://vpopmail.sf.net/ QmailAdmin - web interface for Vpopmail: http://qmailadmin.sf.net/

[Dovecot] Dovecot/SeLinux issues after RHEL5.1 upgrade
by Ion Soltan 28 Jan '08

28 Jan '08

Hello to everyone on the list, I have upgraded my RHEL4 to RHEL5.1 yesterday (all updates have been applied to it as well). I used to have dovecot v0.99.11 on the old system. Everything was working fine. Now I have 5.1 and its respective dovecot v1.0.rc15. Upon upgrading to RHEL5.1, dovecot no longer works correctly. The first thing I did after rewriting the config file for the updated version, was to check my own email. It works fine. However, no other user on the system can check his/hers. Here is what the log shows for everyone except myself: ============================ Jan 27 13:56:41 warp dovecot: POP3(jj): open() failed with file /home/jj/mail/.imap/INBOX/dovecot.index.log: Permission denied Jan 27 13:56:41 warp dovecot: POP3(jj): open() failed with file /home/jj/mail/.imap/INBOX/dovecot.index.log: Permission denied Jan 27 13:56:41 warp dovecot: POP3(jj): Couldn't open INBOX: Internal error occurred. Refer to server log for more information. [2008-01-27 13:56:41] ============================ There are NO complaints reported by selinux in the logs. If I setenforce 0 (disable selinux), everything is working fine for everyone. If I disable selinux monitoring on dovecot (setsebool dovecot_disable_trans 1), nothing changes, which makes me think that something else is causing the problem. I do very much want to use selinux, however, I cannot figure out what the problem is and I have been trying for many hours. Can anyone help? Thanks, Ion

[Dovecot] dovecot servers hanging with fuse/glusterfs errors
by Jordi Moles 28 Jan '08

hi. i've got a clustered mail system with glusterfs and some postfix, squirrelmail and dovecot machines sharing the same storage system through glusterfs. each server has only postfix or squirrel or dovecot installed on it. The thing is... dovecot servers hang very often and the last thing they always log is this: ************* login: Unable to handle kernel paging request at 0000000000100108 RIP: [<ffffffff88020838>] :fuse:request_end+0x45/0x109 PGD 1f729067 PUD 1faae067 PMD 0 Oops: 0002 [1] SMP CPU 0 Modules linked in: ipv6 fuse dm_snapshot dm_mirror dm_mod Pid: 678, comm: glusterfs Not tainted 2.6.18-xen #1 RIP: e030:[<ffffffff88020838>] [<ffffffff88020838>] :fuse:request_end+0x45/0x109 RSP: e02b:ffff88001f04dd68 EFLAGS: 00010246 RAX: 0000000000200200 RBX: ffff88001db9fa58 RCX: ffff88001db9fa68 RDX: 0000000000100100 RSI: ffff88001db9fa58 RDI: ffff88001f676400 RBP: ffff88001f676400 R08: 00000000204abb00 R09: ffff88001db9fb58 R10: 0000000000000008 R11: ffff88001f04dcf0 R12: 0000000000000000 R13: ffff88001db9fa90 R14: ffff88001f04ddf8 R15: 0000000000000001 FS: 00002b29187c53b0(0000) GS:ffffffff804cd000(0000) knlGS:0000000000000000 CS: e033 DS: 0000 ES: 0000 Process glusterfs (pid: 678, threadinfo ffff88001f04c000, task ffff88001fc5a860) Stack: ffff88001db9fa58 ffff88001f676400 00000000fffffffe ffffffff88021056 ffff88001f04def8 000000301f04de88 ffffffff8020dd40 ffff88001f04ddb8 ffffffff80225ca3 ffff88001de23500 ffffffff803ef023 ffff88001f04de98 Call Trace: [<ffffffff88021056>] :fuse:fuse_dev_readv+0x385/0x435 [<ffffffff8020dd40>] monotonic_clock+0x35/0x7d [<ffffffff80225ca3>] deactivate_task+0x1d/0x28 [<ffffffff803ef023>] thread_return+0x0/0x120 [<ffffffff802801d3>] do_readv_writev+0x271/0x294 [<ffffffff802274c7>] default_wake_function+0x0/0xe [<ffffffff803f0976>] __down_read+0x12/0xec [<ffffffff88021120>] :fuse:fuse_dev_read+0x1a/0x1f [<ffffffff802804bc>] vfs_read+0xcb/0x171 [<ffffffff802274c7>] default_wake_function+0x0/0xe [<ffffffff8028089b>] sys_read+0x45/0x6e [<ffffffff8020a436>] system_call+0x86/0x8b [<ffffffff8020a3b0>] system_call+0x0/0x8b Code: 48 89 42 08 48 89 10 48 c7 41 08 00 02 20 00 f6 46 30 08 48 RIP [<ffffffff88020838>] :fuse:request_end+0x45/0x109 RSP <ffff88001f04dd68> CR2: 0000000000100108 dovecot01gluster01 kernel: Oops: 0002 [1] SMP dovecot01gluster01 kernel: CR2: 0000000000100108 <3>BUG: soft lockup detected on CPU#0!

[Dovecot] Howto set mail_location for system users over LDAP?
by Patrick Ben Koetter 28 Jan '08

28 Jan '08

In parallel to /etc/passwd I do have my system users in LDAP. I want to store their messages in /srv/mail/state-of-mind/<username>. Dovecot has been configured to retrieve the extra field mail to override the mail_location setting. I can see in the log it retrieves the correct information as long as I run Dovecot deliver as Postfix service 'dovecot' as shown in section "Virtual users" <http://wiki.dovecot.org/LDA/Postfix>. However if I use deliver as specified for "System users" it ignores the LDAP settings and delivers messages to my users $HOME directory as specified in /etc/passwd. Is this correct behaviour? What do I need to do to use the Postfix $mailbox_command _and_ have Dovecot deliver honor my LDAP settings?

[Dovecot] Thunderbird Problem - What causes this?
by Marc Perkel 28 Jan '08

28 Jan '08

Strange problem and I'm not sure what's causing it. I'm using IMAP. A new message arives in the inbox. I see it displayed in the message list in bold. I click on the message and it looks like it's reading it by the previous message that was in the window remains and the new message is still bold (unread). However I can then click on an old message and then click on the new message again and it reads. I have also seen Thunderbird be in a somewhat unresponsive state. You can click on messages and they don't read. But Shutting down Thunderbird and restarting it make it responsive again. Has anyone seen this?

[Dovecot] proxy configuration
by bill-dovecot＠carpenter.ORG 27 Jan '08

27 Jan '08

Before I spend some time experimenting with what might be impossible, maybe someone can just tell me (either "how" or that it's impossible). I'd like to get perdition out of my environment (mainly to have one less moving part in my architecture). I'm looking at dovecot's built-in proxying. In my setup, I don't have dedicated front-end machines. A user can connect to any server, but their mail files live on one particular machine. I'd like to transparently proxy them from whatever machine they happen to hit to their home machine. Except for the "proxy_maybe" feature advertised for dovecot 1.1, I don't see a surefire way to do this. Has anyone done it, or can anyone say for sure that it can't reasonably be done until "proxy_maybe"?

[Dovecot] Thunderbird trouble with Dovecote and dbox
by Hannes Dorbath 27 Jan '08

27 Jan '08

Hi, I'm new to Dovecot -- migrating from Cyrus. Version and config: # 1.1.beta14: /etc/dovecot/dovecot.conf protocols: imaps login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login mail_location: dbox:/data/mail/%u auth default: passdb: driver: pam args: * userdb: driver: passwd Linux 2.6.22-gentoo-r10 x86_64 GNU/Linux I have chosen dbox as mailbox format as it is claimed to be the best performing -- and performance is the reason I'd like to migrate away form Cyrus. I'm aware that dbox might not be 100% mature, but I'm good at doing backups. Anyway, so far I have the following problems: - Greyed out Inbox After creating a new user and connecting to that account with Thunderbird the first time, the INBOX folder is greyed out and in italic. Restarting Thunderbird 3-4 times seems to fix the problem. Google suggests that other people have seen the same, but they never found a solution. - After creating sub folders they are not displayed, I need to manually subscribe to them after creation. - When "Trash" contains folders, Thunderbird is unable to "Empty Trash". While the folder is removed from Thunderbird's folder tree, it's there again after a restart of Thunderbird. - Deleted folders are never deleted from the file system. I'm not sure if this is intended with dbox. - Moving folders via drag & drop does not work, it just does nothing. So basically nothing besides reading existing mails seems to work reliable. My basic questions now is, are those problems related to dbox, or to Dovecot and Thunderbird in general? -- Best regards, Hannes Dorbath

[Dovecot] User-specific mail_location using passwd database
by Maxime Brugidou 26 Jan '08

26 Jan '08

current version : 1.0.rc15 Hi, I would just like to know if it's possible to have different mail locations for different UNIX users, using pam authentication and the passwd userdb. We also have some virtual users using an SQL db. The current config is : auth default: username_translation: %@ verbose: yes debug: yes passdb: driver: pam passdb: driver: passwd passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: passwd userdb: driver: sql args: /etc/dovecot/dovecot-sql.conf Then we can only modify mail locations for virtual users on the sql userdb. But how could we change it for real users ? Thanks for help, -- Maxime Brugidou

[Dovecot] Dovecot LDA (deliver) stopped working
by falz 26 Jan '08

26 Jan '08

Hello, One day a week or so ago, a server that's Postifx w/ Local users, dovecot w/ LDA decided to stop working. The only thing that stopped is the LDA portion, the rest all works fine. I also posted to the postfix mailing list yesterday but wasn't able to debug any further. Here's the situation: if I use mailbox_command to point to deliver, postfix will always put the message in the deferred queue. However, if I run deliver from the command line, it works fine. I've recompiled Dovecot and Postfix cleanly and reinstalled a few times to ensure permissions are OK. It's not a virtual setup, so I do NOT have setuid root on the deliver binary. Postfix people suggested placing a wrapper script for mailbox_command, which I did, and have it log to a text file, so I do know that deliver is being called. However, although I have LDA debug logging on, and it DID log prior to this, when postfix supposedly calls deliver, dovecot does NOT log anything. It DOES however log if I call deliver from any account (root or not) from the command line (ls / | /path/to/deliver -d localaccountname). Any way I can debug this further? I would assume that deliver would log something even if it's called, but it appears that it does not. My postfix related details are here: http://marc.info/?l=postfix-users&m=120119147917409&w=2 I followed the postfix/lda wiki (http://wiki.dovecot.org/LDA/Postfix) when setting it up, and it worked perfectly for months. I did indeed only have to change mailbox_command and it worked (I'm also using sasl auth, but that should be unrelated). Obviously something happened on my system, but I would assume recompiling/reinstalling would reset things. Nothing in the config files for postfix or dovecot changed, from what I can see, as generally I am the only one making changes. Thanks, --falz

[Dovecot] Capturing credentials for imap sync
by Master Abi 26 Jan '08

26 Jan '08

Hi List All the imap sync apps I could find requires the username /password credentails to be known before a sync occurs. I have Dovecot using ldap acting as a nearline backup mail server to MS Exchange. Every hour imapsync syncs mail between Exchange and Dovecot. This all works fine becuase the users credentials are known, but when new users are added I would like the process to work seemless like this: The user is added to the Active Directory. The mail client is configured with 2 accounts with identical credentials, one of which is connected to Dovecot. When the new client connects to dovecot, the credentials are captured and stored so that imapsync can use it. This If there is another way this can be done with dovecot, could I please be enlighten. I have read the doco on migration but I am not quite migrating but more replicating. Thank you

[Dovecot] symbolic links to root node
by Martin Preen 25 Jan '08

Hello, I have a question about the way Dovecot limits file system access. Currently we're using Dovecot 1.0.5 (Solaris 10). In some cases users have a symbolic link like "z: -> /" in their mail directory. As a result there are log entries like Jan 25 13:30:31 imap1 dovecot: [ID 107833 mail.error] IMAP(xyz): stat(/home/xyz/.wine/dosdevices/c:/windows/profiles/xyz/.../z:/proc/28381/root/proc/28381/.../root/proc/28381/Player/#SharedObje Jan 25 13:30:31 imap1 dovecot: [ID 107833 mail.error] IMAP(xyz): x) failed: File name too long We know the reason (the links are create by Wine) but unfortunately we cannot get rid of them. Is there something I can do (these links should be ignored) ? Or is it a bug ? Greetings.

[Dovecot] New server error
by Anne Wilson 25 Jan '08

25 Jan '08

I'm setting up a replacement mail server on a CentOS 5.1 box. The dovecot version is 1.0.rc15. 'dovecot -n' returns # /etc/dovecot.conf login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 auth default: passdb: driver: pam userdb: driver: passwd I can telnet localhost 143 and log in. I have given kmail the address of the server and an Inbox has been created, but no option to create sub-folders. If I attempt to send a message kmail freezes. Clearly something's wrong. I am using configuration files from the old server, modified only to the new server details. I have alias and transport hashes. What else should I be looking at? Thanks Anne

[Dovecot] dovecot + antispam + sendmail
by Anil 25 Jan '08

Whats a good antispam solution? I am using sendmail and dovecot 1.1. I came across dovecot's antispam plugin, but it seems it does not support 1.1 yet. I am also looking for something non-perl based. I am already doing some greylisting with sendmail milter. Any other good suggestions? If not, I guess I might have to downgrade back to 1.0 dovecot. Thanks

[Dovecot] Is there a way to limit multiple POP3 connections?
by patrickm 25 Jan '08

Hi all, Please correct me if I'm going about this the wrong way. We currently have a 3 system Mail server set up - two machines are the load balanced frontends running Dovecot and Postfix, and the third machine is our NFS. Over the past 4 months or so, I've tweaked and optimized our mail servers, and we receive roughly 3 million emails a day combined through this setup. Sometimes, the IO Wait is horrible on the load balanced servers - it can get up into the 80-90% range sometimes - it's usually when a lot of email is being passed, or there are a lot of POP3 and IMAP connections. One item which I believe to be hurting I/O performance is the fact I used a RAID 10 setup using SATA II drives on an LSI Logic SATA I controller, in 32 bit mode. Until we rebuild our mail setup (which may be another year down the road), I want to make sure these servers are optimized to the fullest just in case we get heavy I/O usage, it doesn't slow down if at all possible. One thing I noticed is that when issuing a 'ps aux | grep -i pop' or 'ps aux | grep -i imap' I see the same username 2,3,4,5 times, sometimes more. When issuing a 'tail -f /var/log/dovecot.log' I notice that some users log into POP3 every 3 seconds, sometimes sooner. Without upsetting the customer, is there anything I can do on my end to disallow people logging into POP3 multiple times at once? Any tips on this is very much appreciated. Thanks in advance. Patrick
