[Dovecot] inet_listener imaps { port = 0 } question
by henrixd 01 Jun '12

01 Jun '12

Hi Why commenting out "inet_listener imaps {}" won't stop dovecot to listen port 993? I think this would be expected behavior. Just curious, finally got it working with port = 0. :) - Henri

Re: [Dovecot] High level of pop3 popping causing server to become unresponsive
by Root Kev 30 May '12

Missed CCing on last reply. See below.. Also, would having Nagios checking the number of messages in a mailbox cause issues with the popping of messages? And/Or would having a user accessing the mailbox from two different applications cause issues? Ie. from Outlook and mobile device? I am under the impression that a lock file is generated which should deal with the issue of contention, deleting mail, etc. Thanks for any information.

Show your doveconf -n output and what error messages you see. Attached to this email (dovecot 2.0 and 2.1 -n outputs) In both cases, we use the same local config file, included from dovecot.conf (I've included both of these too) The error message is: May 30 17:00:31 msslat dovecot: imap(foobar): Error: user foobar: Initialization failed: namespace configuration error: Duplicate namespace prefix: "" May 30 17:00:31 msslat dovecot: imap(foobar): Error: Invalid user settings.

[Dovecot] Strange Dovecot 2.0.20 auth chokes and cores

[Dovecot] i can't make DOTS before mailbox names
by John Goodner 30 May '12

30 May '12

hello i have a real stumper of an issue here and need some help! (config posted below) ok, so i'm building out a new mail system with v1.2.15 of dovecot on debian6 this new system is being designed to seamlessly migrate from an older dovecot mail system (v1.1.3). i have everything almost perfect but i've hit a wall which I need help on. so the existing mailboxes on the old server are as such: cur dovecot.index dovecot.index.cache dovecot.index.log dovecot-uidlist dovecot-uidvalidity dovecot-uidvalidity.4fbffa1a .INBOX.Drafts .INBOX.Sent .INBOX.Trash new subscriptions tmp .Trash NOTICE that it puts the . in before INBOX now on the new mailserver I get this: cur dovecot.index.cache dovecot.index.log dovecot-uidlist dovecot-uidvalidity dovecot-uidvalidity.4fc03e57 Drafts INBOX new Sent subscriptions tmp Trash Notice how it's no longer using DOTS before the names. so what i need to do is make the new mail server DUPLICATE EXACTLY the folder layouts of the old server. i've tried fussing with Namespace and the MailDir and especially the PREFIX option which is seems to ignore a '.' to start a filename. i also fussed with the autocreate hoping i could find something there to adjust. but no good. no matter what i do I can't get it to make or read .Trash .Sent .Drafts! please help me! any advice would be appreciated. i'm also willing to hire someone to finish up the config for me. shouldn't take more than a couple hours. thanks! jg here's my config: root@mailserver1:/# dovecot -n # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-686 i686 Debian 6.0.5 nfs log_path: /var/log/dovecot.log log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s 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 mail_location: maildir:/var/vmail/%d/%n@%d:INBOX=/var/vmail/%d/%n@%d:LAYOUT=fs mbox_write_locks: fcntl dotlock mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 namespace: type: private separator: . prefix: .INBOX. inbox: yes list: yes subscriptions: yes lda: log_path: /var/log/dovecot-deliver.log auth_socket_path: /var/run/dovecot/auth-master postmaster_address: postmaster(a)m.minla.net mail_plugins: sieve global_script_path: /home/vmail/globalsieverc auth default: passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: static args: uid=1010 gid=1010 home=/home/vmail allow_all_users=yes socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: vmail

http://dovecot.org/releases/2.1/dovecot-2.1.7.tar.gz http://dovecot.org/releases/2.1/dovecot-2.1.7.tar.gz.sig * Session ID is now included by default in auth and login process log lines. It can be added to mail processes also by adding %{session} to mail_log_prefix. + Added ssl_require_crl setting, which specifies if CRL check must be successful when verifying client certificates. + Added mail_shared_explicit_inbox setting to specify if a shared INBOX should be accessible as "shared/$user" or "shared/$user/INBOX". - v2.1.5: Using "~/" as mail_location or elsewhere failed to actually expand it to home directory. - dbox: Fixed potential assert-crash when reading dbox files. - trash plugin: Fixed behavior when quota is already over limit. - mail_log plugin: Logging "copy" event didn't work. - Proxying to backend server with SSL: Verifying server certificate name always failed, because it was compared to an IP address.

[Dovecot] Different SSL requirements for connections on different ports?
by William Gallafent 29 May '12

29 May '12

Hi All, I'm running dovecot 2.0.19. I currently have remote users access mail using IMAP over SSL, with their client certificates being both required and verified. I do this using "ssl = required" and "ssl_verify_client_cert = yes". I would now like to add a webmail front-end (squirrelmail) running on the same server. In order to achieve this I would like to have squirrelmail connecting locally using IMAP, but without the certificate requirement. I'm happy to use the standard IMAP port for this, since that port is firewalled so that only localhost has access. Do I need to run two separate dovecot instances in order to achieve this, or can I somehow configure different SSL requirements for the two ports? Is there a way to have the ssl directives I mention above active only for a certain port (or for certain hosts, i.e. non-local?) I've been looking around in the documentation, but I haven't yet worked out how to do this other than by having two separate dovecot instances running, with the different auth configurations. Is that the best approach, or can I get it working with only once instance? Thanks for any help! -- Bill Gallafent.

[Dovecot] Director and backend on the same server
by James Devine 29 May '12

29 May '12

I have setup director and a backend dovecot service on the same machine using different ports. The backend service is listening on the default 24, 110 and 143 for lmtp, pop3 and imap respectively. Director is listening on 10024, 10110 and 10143 for the same respective services. I can get this setup to work if I have one backend server on a different IP listening on 10024, it seems director tries to use the same port it is listening on when making backend connections. If I point it to the local backend server, it tries to connect to itself which fails. Is there a way to specify the backend ports that director tries to connect to? I see there is a way to specify the port in director_servers but I'm not sure how I would specify the different ports for the different backend services, if this is even possible.

[Dovecot] Crash on force-resync if / is given as mailbox name

[Dovecot] Dovecot 2.1 mbox + maildir
by Alan Brown 29 May '12

29 May '12

What syntax is needed to make this work? The 2.0 wiki recomendations don't work - I can see the inboxes or the folders but not both at once and there are lots of error messages about prefix clashes if I simply use the existing 2.0.20 conf file on 2.1.6 The layout I have is: Inboxes in mbox format - /var/spool/mail/%u Folders in maildir format - /var/spool/imap/%u/Maildir/ Control and index folders are under separate trees (/var/spool/control & /var/spool/indexes) There's also a mbox area mainly for moving oversized inboxes (/var/spool/imap/%u/mbox/ - prefixed as OLD) Presumably I'm not the only one who's had problems of this type? Thanks in advance for any help Alan

[Dovecot] Bug report - crash on group lookup
by Peter Meier 29 May '12

29 May '12

Hi I was doing some migration from a 1.2 installation to a 2.1. While testing my new installation dovecot crashed at two test-cases constantly with with a "Panic: Trying to allocate 0 bytes" message. Both times it was because I was using a wrong group (or none) in my config. The output I got by dovecot was not that helpful. I only figured it out, that it has something to do with the group by looking at the code, to figure out where the stacktrace I got could come from. Unfortunately, I don't remember one of the examples anymore that correctly (except that it was also a group configuration related issue). The other example, was that I was testing the quota warning scripts: Normal delivery worked fine, but as soon as dovecot should send a quota warning, after the mail got already delivered, I received said panic. For the MTA the mail delivery failed (-> bounce), although the LDA already delivered the mail, but failed in post processing (sending the quota warning). My fix was to add: unix_listener quota-warning { group = mail mode = 0660 } to the quota warning service. The LDA process has an own user per mailbox and the mail group. It looks to me as it would panic by looking up the user of the lda process, but that's pure guess. Attached is a debug output and the configuration that triggered the problem. I see two problems: 1. Don't panic while "looking" up a group 2. Give a meaningful error messages. If you have any further questions, please let me know. ~pete ==> /var/log/dovecot/debug.log <== May 25 12:19:50 lda: Debug: Loading modules from directory: /usr/lib/dovecot May 25 12:19:50 lda: Debug:

Hello everyone ! I'm trying to make a mail server with dovecot and postfix. Users will authenticate with Active Directory server. I've got an problem with Dovecot. To make the mail server, I'm using IredMail, and I used this tutorial : http://www.iredmail.org/wiki/index.php?title=Integration/Active.Directory.i… here Here's my dovecot-ldap.conf : hosts = dc.domain.lan:389 ldap_version = 3 auth_bind = yes dn = vmail(a)domain.lan dnpass = vmail_passwd base = ou=some_ou,dc=domain,dc=lan scope = subtree deref = never user_filter = (&(userPrincipalName=%u)(objectClass=person)(!(userAccountControl:1.2.840.113556.1.4.803:=2))) pass_filter = (&(userPrincipalName=%u)(objectClass=person)(!(userAccountControl:1.2.840.113556.1.4.803:=2))) user_attrs = =home=/home/mail/%Ld/%Ln/Maildir/,=mail=maildir:/home/mail/%Ld/%Ln/Maildir/ pass_attrs = userPassword=password default_pass_scheme = CRYPT With this configuration file, it works. BUT : To allow Dovecot to find users in my AD database, I must specify an OU in "base". If I only set "dc=domain,dc=lan" the research doesn't work. It seems that Dovecot is not capable to make a research without an OU specified in base. Am I wrong ? The root research works fine with postfix, samba+winbind, and I've an enterprise sized hardware firewall, and it works fine too. I'll be surprised if you tell me that Dovecot can't make a research without OU... That's why I'm posting here.. I've already post about this problem on the Iredmail forum, http://www.iredmail.org/forum/post15184.html#p15184 here , but no solution were found. You're my last hope :) Thanks a lot for replies Nicolas -- View this message in context: http://old.nabble.com/Active-Directory-%3A-searches-in-root-tree-tp33881379… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] GETQUOTAROOT under roundcube
by Adam Szpakowski 29 May '12

29 May '12

Hi, I'm struggling with the proper quota displaying under roundcube webmail. I've tracked the problem to the different responses on GETQUOTAROOT command. Roundcube aquire quota usage using IMAP command: GETQUOTAROOT INBOX Example dump of the roundcube <-> dovecot communication: > GETQUOTAROOT inbox < QUOTAROOT "inbox" "User quota" < QUOTA "User quota" (STORAGE 1198415 10485760) < OK Getquotaroot completed. The same communication using python imaplib: > GETQUOTAROOT inbox < QUOTAROOT "inbox" "User quota" < QUOTA "User quota" (STORAGE 1431260 10485760) < OK Getquotaroot completed. Quota reported to python client is the same as the one reported to Thunderbird and seems to be the proper one. Python test was performed from the webmail same server, the same user. Can someone point me in the right direction? If there is no explanation on IMAP level i'll move the question to roundcube list. software used: - dovecot: 2.0.15, quota limit set in LDAP, usage tracked in SQL - roundcube: 0.7 - python: 2.6.7 Relevant parts of the dovecot config (taken selectively from different files): quota = dict:User quota::proxy::quota quota_rule2 = Trash:storage=+10%% quota_rule3 = spam:storage=+10%% user_attrs = mailQuota=quota_rule=*:bytes=%$ mail_plugins = quota imap_quota dict { quota = mysql:/etc/dovecot/dovecot-dict-used-quota.conf.ext } #dovecot-dict-used-quota.conf.ext map { pattern = priv/quota/storage table = used_quota username_field = username value_field = bytes } map { pattern = priv/quota/messages table = used_quota username_field = username value_field = messages } -- Adam Szpakowski

[Dovecot] per-mailbox message limits
by Alan Brown 29 May '12

29 May '12

This is something Timo hacked up for me a few years ago and I realised should be on the list in case anyone else wants them. The following patches will limit maildir folders to 4000 messages on Dovecot 2.0.* and 2.1.* The Specfile patch is against the Cityfan Redhat EL5 SRPM but is likely to work on most build platforms Changing the message limit requires a recompile. It's brutal and ugly but it prevents users overloading FSes that can't cope with huge numbers of files (EG: GFS2)

[Dovecot] (no subject)
by Phil Petree 29 May '12

29 May '12

Hey All, I'm developing a site on a VPS that comes stock with dovecot 1.2.17 and I'm trying to setup some functionality that is very specific to our business model. My question is this: How do I create (programatically) aliases for a forwarder? I have an address, email(a)domain.com that gets sent to a php script and I want users to be able to send to that script via any number of different names (could ultimately be 1000's). I'm thinking that I append/delete from the etc/aliases file and then run #newaliases So that email(a)domain.com will answer on dummy(a)domain.com or dothis(a)domain.com, once the email comes in, I can check the header, get who it was really sent to, do all my checks, perform the necessary action blah blah blah... and be able to do it all on one piece of code (my fantasy LOL). Am I on the right track here or is this simply not going to work? Thanks, Pete

[Dovecot] AUTH PLAIN fails while AUTH LOGIN succeeds with Exim -> Dovecot SASL auth
by Sandro Tosi 29 May '12

29 May '12

Hello, we're trying to setup a platform with authenticated SMTP with exim and relying on dovecot as auth agent. We've read http://wiki2.dovecot.org/HowTo/EximAndDovecotSASL and so made the changes mentioned there, also setting auth_mechanisms = plain login in conf.d/10-auth.conf . With this setup, we're able to use AUTH LOGIN method on an SMTP session, but using AUTH PLAIN fails. What we receive in the SMTP session is: auth plain `echo -e -n `\0user\0password' | mimencode` 535 Incorrect authentication data (it's actually the output of that command that we put there), and in the dovecot log we see: 2012-05-24 15:04:20 auth: Debug: client in: AUTH 1 PLAIN service=smtp secured rip=127.0.0.1 lip=127.0.0.1 nologin resp=<hidden> 2012-05-24 15:04:20 auth: Info: plain(?,127.0.0.1): invalid input Do you know where we can look to resolve this problem?

[Dovecot] Released Pigeonhole v0.3.1 for Dovecot v2.1.6
by Stephan Bosch 27 May '12

27 May '12

Hello Dovecot users, It's been a few months since the last Pigeonhole release. The main reason is that I've introduced a few big new features. Although the new features themselves probably haven't seen much testing so far, I'm now pretty confident that existing configurations are not broken by these changes. The biggest change is the addition of dict support for Sieve script retrieval. It now possible to fetch Sieve scripts from an SQL database using the Dovecot dict facility. Read the INSTALL file and the referenced additional documentation for more information. Note that this feature currently is not usable with sieve_before/sieve_after and ManageSieve. Additionally, it is now possible to specify multiple sieve_before and sieve_after scripts. This for instance enables administrators to specify both global and user-specific scripts that are to be executed before and after the user's personal script. User-specific scripts configured in sieve_before and sieve_after can not be seen or changed through the ManageSieve protocol. Finally, as promised a while back, I've incorporated the vnd.dovecot.duplicate extension into the main Pigeonhole package. Using this Dovecot-specific extension it is possible to detect duplicate deliveries (such as for example caused by mailing list subscriptions). The detection is based on the message ID and uses the same database file (~/.dovecot.lda-dupes) as the vacation extension. Since the changes introduced in the release are rather large, I strongly advise you to experiment with it a bit before deployment. Changelog v0.3.1: * Added support for retrieving Sieve scripts from dict lookup. This means that Sieve scripts can now be downloaded from a database. Compiled script binaries are still put on disk somewhere if used. The INSTALL documentation is updated with information on this new feature and the (backwards-compatible) changes to the configuration. Note that his feature is currently not supported for sieve_before/sieve_after or script management through ManageSieve. + Incorporated the sieve_duplicate plugin into main Pigeonhole tree as a normal extension (vnd.dovecot.duplicate). This Dovecot-specific extension adds the ability to check for duplicate deliveries based on message ID. Specification can be found in: doc/rfc/spec-bosch-sieve-duplicate.txt + Added support for specifying multiple sieve_before and sieve_after paths. This adds much more flexibility to the multiscript configuration. One application is to have user-specific Sieve scripts outside the user's normal control through ManageSieve. + Added a "session ID" string for managesieve connections, available in %{session} variable (analogous to Dovecot change). - Fixed several small issues, including a few potential segfault bugs, based on static source code analysis. - ManageSieve: changed use of EPROTO error to EIO in ManageSieve string stream implementation because it is apparently not known in BSD. - Gave stamp.h.in (needed for autotools) some content to prevent it from disappearing in patch files. - Fixed bug that caused a SunStudio CC compile failure (reported by Piotr Tarnowski). The release is available as follows: http://www.rename-it.nl/dovecot/2.1/dovecot-2.1-pigeonhole-0.3.1.tar.gz http://www.rename-it.nl/dovecot/2.1/dovecot-2.1-pigeonhole-0.3.1.tar.gz.sig Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information. Have fun testing this new release and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

[Dovecot] Checkpassword Perl LDAP Implementation
by Jeff Hardy 27 May '12

27 May '12

A few years back I hacked up a perl chkpassldap.pl script to authenticate against ldap, and optionally authorize against groups and/or ldap attributes. This works with both qmail and Dovecot, and it also supports a somewhat generic method to alter the environment suitable to use for Dovecot as a prefetch userdb. Anyway, I have been running the script on a qmail-ldap and Dovecot 1.2 proxying cluster using the stock qmail-ldap attributes without any troubles, and figured I would finally release it in the thought someone might find it useful. http://fritz.potsdam.edu/projects/chkpassldap I tried to document the ins and outs of userdb configuration. If anyone finds anything that could use correction or clarification, please let me know. It has been awhile since I was in the middle of it all. Cheers, -Jeff -- Jeffrey Hardy Network / Systems Administrator hardyjm(a)potsdam.edu

[Dovecot] Dovecot usage values differ from actual disk usage
by Daniel Parthey 26 May '12

26 May '12

Hi, in my dovecot setup the accounting database table shows wrong values which do not correspond with the actual disk space used. The disk usage says 2.6 Gigabytes: mail01:~# du -sh /mail/dovecot/example.org/username 2.6G /mail/dovecot/example.org/username While the doveadm quota get says 7 Gigabytes for the same user: mail01:~# doveadm -f tab quota get -u username(a)example.org Quota name Type Value Limit % User quota STORAGE 7065208 - 0 User quota MESSAGE 282024 - 0 mysql> select * from dovecot.dovecot_usage where username="username(a)example.org"; +----------------------+------------+----------+ | username | storage | messages | +----------------------+------------+----------+ | username(a)example.org | 7234773131 | 282024 | +----------------------+------------+----------+ 1 row in set (0.00 sec) What might be the reason for such huge differences (several gigabytes) between storage value in dovecot_usage table and disk usage value? After a quota recalc everything is correct: mail01:~# doveadm quota recalc -u username(a)example.org mail01:~# doveadm -f tab quota get -u username(a)example.org Quota name Type Value Limit % User quota STORAGE 2630434 - 0 User quota MESSAGE 100714 - 0 mysql> select * from dovecot.dovecot_usage where username="username(a)example.org"; +----------------------+------------+----------+ | username | storage | messages | +----------------------+------------+----------+ | username(a)example.org | 2693565239 | 100714 | +----------------------+------------+----------+ 1 row in set (0.00 sec) How can I keep the accounting data consistent with actual disk usage, without running a recalc cronjob every few hours? There's running a dovecot director and mailbox instance on each of our servers with the mails being stored on NFS and received from postfix via LMTP through the director lmtp port 20024. Configuration of director (dovecot-director.conf) and mailbox (dovecot.conf) is attached. Kind regards Daniel

[Dovecot] Valid config for lda_mailbox_autosubscribe with dovecot 1.2?
by Joan 25 May '12

25 May '12

Hi, Due to some reasons I've to support both dovecot 1.2 and dovecot 2.x, and I just found that the -s parameter I used to autosubscribe to sieve folders doesn't exist anymore in dovecot 2.x The problem arises because (AFAIK) in postfix's master.cf you can only specify one configuration, and I used to have this: dovecot unix - n n - - pipe flags=DRhu user=vmail argv=/usr/lib/dovecot/deliver -f ${sender} -d ${recipient} -s Is there any way to make the config compatible for both versions, achieving the autosubscribe and not crashing dovecot?

[Dovecot] Berkeley DB with Dovecot
by Jerry 23 May '12

23 May '12

I have a friend who is preparing to set up a small Postfix/Dovecot mail system. There are only approximately 25 users. He wants to use Berkeley DB in a similar fashion to the way Postfix does. I told him I do not believe Dovecot supports that. I could not find any documentation relating to it. 1) Does Dovecot support Berkeley DB? 2) Are their any plans to incorporate that feature into Dovecot? It seems like it could potentially be a very useful feature. I have used it myself when a full blown MySQL configuration seemed like over-kill on other small projects. -- Jerry ♔ Disclaimer: off-list followups get on-list replies or get ignored.

Re: [Dovecot] BEWARE: This list is being harvested for leads
by Douglas Mortensen 20 May '12

I personally didn't mind a one-time notice from the dev's team that that are now offering paid commercial support. What if I WANTED it? I felt like it was a courtesy email from them to let me know that it's available. If those emails continue unsolicited, then it may start to feel like spam to me, but this did not. In general, I've actually been looking for ways to financially support good open source projects. I have worked with many & find that oftentimes, the ones with hood commercial support tend to be ones that have the manpower resources needed to quickly fix bugs, patch vulnerabilities, maintain a strong development schedule & give decent support through mailing lists & similar means.

[Dovecot] Best way to change index location on mdbox
by Patrick Westenberg 20 May '12

20 May '12

Hi, right now my index directory is part of the users home directory: mail_home = /var/mail/%d/%n mail_location = mdbox:~/mdbox I want the indexes to be stored in a different location: mail_home = /var/mail/%d/%n mail_location = mdbox:~/mdbox:INDEX=/var/indexes/%d/%n If I just switch this setting and reload the configuration, no e-mails are shown to the user. After restoring the whole maildir I deleted all dovecot.index.*-files from that user and starting dovecot with the new index directory setting, I got the following error after connecting. I expected the index files to be regenerated but I got an error: May 18 23:11:12 imap(test(a)example.com): Panic: file mail-storage.c: line 787 (mailbox_check_mismatching_separators): assertion fail ed: (strncmp(vname, ns->prefix, ns->prefix_len-1) == 0) May 18 23:11:12 imap(test(a)example.com): Error: Raw backtrace: /usr/local/lib/dovecot/libdovecot.so.0(+0x4475a) [0x7f993f60875a] -> /usr/local/lib/dovecot/libdovecot.so.0(+0x447a6) [0x7f993f6087a6] -> /usr/local/lib/dovecot/libdovecot.so.0(i_error+0) [0x7f993f5df5bf] - > /usr/local/lib/dovecot/libdovecot-storage.so.0(mailbox_open_stream+0) [0x7f993f8ccca0] -> /usr/local/lib/dovecot/libdovecot-storage.so. 0(mailbox_open+0xf) [0x7f993f8cccbf] -> /usr/local/lib/dovecot/libdovecot-storage.so.0(mdbox_storage_rebuild_in_context+0xb2b) [0x7f993f8 8eeab] -> /usr/local/lib/dovecot/libdovecot-storage.so.0(mdbox_sync_begin+0x7ec) [0x7f993f88ce7c] -> /usr/local/lib/dovecot/libdovecot-st orage.so.0(mdbox_sync+0x46) [0x7f993f88cee6] -> /usr/local/lib/dovecot/libdovecot-storage.so.0(mdbox_storage_sync_init+0x87) [0x7f993f88c fc7] -> /usr/local/lib/dovecot/libdovecot-storage.so.0(mailbox_sync_init+0x31) [0x7f993f8cb851] -> /usr/local/lib/dovecot/libdovecot-stor age.so.0(mailbox_sync+0x27) [0x7f993f8cc387] -> /usr/local/lib/dovecot/libdovecot-storage.so.0(index_storage_get_status+0x28f) [0x7f993f8 ef41f] -> dovecot/imap(imap_status_get+0x7a) [0x41756a] -> dovecot/imap(cmd_status+0x14f) [0x40e85f] -> dovecot/imap(command_exec+0x3d) [ 0x41158d] -> dovecot/imap() [0x41050e] -> dovecot/imap() [0x4105ed] -> dovecot/imap(client_handle_input+0x135) [0x410815] -> dovecot/imap (client_input+0x5f) [0x41113f] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x36) [0x7f993f6148f6] -> /usr/local/lib/dovecot /libdovecot.so.0(io_loop_handler_run+0x9f) [0x7f993f61592f] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_run+0x28) [0x7f993f614898] -> /usr/local/lib/dovecot/libdovecot.so.0(master_service_run+0x13) [0x7f993f601023] -> dovecot/imap(main+0x2a4) [0x419364] -> /lib/libc.s o.6(__libc_start_main+0xfd) [0x7f993f280c8d] -> dovecot/imap() [0x408e89] How can I change the index directory without losing mails?

[Dovecot] High level of pop3 popping causing server to become unresponsive
by Root Kev 19 May '12

19 May '12

Hello all, We have put Dovecot 2.1.4 on several of our production servers (CentOS, on Dell R710, with 20GB memory, dual CPU Quad-core). We have a single instance of Dovecot running and currently have several instances of Popa3d. When there are significant amount of popping from 2 mailboxes that dovecot that is popping from (500+ msgs in the mailboxes), the popping of the messages causes the boxes to become unresponsive. We use another application that connects to the Dovecot, downloads 2-10 messages, then processes them, then sends the delete command to Dovecot. When this issue occurs we are unable to become Root, or login again if we close our ssh connection. This only occures when Dovecot is doing the popping. If we only run the older Popa3d, this doesn't occur. We believe it is caused by the way dovecot is authenticating. We are using auth_mechanisms = plain passdb drive = shadow usedb driver = passwd args = blocking=yes If anyone could suggest what could be causing the login issue, we would appreciate any incite to fix it! Thanks, Kevin

[Dovecot] ..::MBOX ISSUE::..
by Alfonso Alejandro Reyes Jimenez 19 May '12

19 May '12

Hi everyone. I have a postfix working with sasl auth and dovecot, everything works fine. I just have 2 issues, the first is that if you add the IMAP mail accounts you can import all the mboxes on the /var/spool/mail/ which we don't want. The second issue is that there's no sent, trash and draft folder, so if we have imap we are not able to store those emails. Basically I would like to know how to fix both but the first one is the most urgent. I thought it was a postfix issue, but it seems not to be. Any ideas? Thanks in advance for your help.

[Dovecot] Authentication with AD and quick mbox question
by Kaya Saman 19 May '12

19 May '12

Hi, I'm attempting to implement Dovecot 2.1.3 built on a FreeBSD 8.2 64 bit system from ports. I had the servicve up and running on a local vbox demo which did a very simple Maildir format sytem which was situated in ~/Maildir. I would now like to expand the system and tie it to a Windows domain. What is the best way to go about doing this? Can Dovecot be directly tied in or do I need to tie the server in to the domain? This is my current dovecot.conf file - which of course I will tweak but as I am currently in the stage of building this is what I have so far: protocols = imap # It's nice to have separate log files for Dovecot. You could do this # by changing syslog configuration also, but this is easier. log_path = /var/log/dovecot.log info_log_path = /var/log/dovecot-info.log # Disable SSL for now. ssl = no disable_plaintext_auth = no # We're using Maildir format #mail_location = maildir:~/Maildir mail_location = mbox:/mail:INBOX=/mail/%u # If you're using POP3, you'll need this: #pop3_uidl_format = %g # Authentication configuration: auth_verbose = yes auth_mechanisms = plain passdb { driver = passwd-file args = /usr/local/etc/dovecot/passwd } userdb { # driver = static # args = uid=root gid=root home=/root/ driver = static args = uid=500 gid=500 home=/ZPOOL_1/%u } Is this correct to use mbox++ format and store under /mail/%u ?? Can anybody give me some advice? Regards, Kaya

[Dovecot] Migration between namespaces breaks outlook on mac's
by Mark Zealey 19 May '12

19 May '12

Hi there, We're running dovecot 1.1 on one set of servers with a courier-imap-like namespace configuration: namespace private { separator = . prefix = INBOX. inbox = yes } We're now migrating customers onto a dovecot-2 platform, switching from Maildir to sdbox (using dsync mirror) & changing the namespace at the same time. New namespace configuration looks like (as taken from http://wiki2.dovecot.org/Namespaces) # This is for courier-imap namespace compatability namespace { type = private separator = / prefix = inbox = yes } namespace { type = private prefix = INBOX. separator = . inbox = no hidden = yes list = no alias_for = } For 99% of clients this works fine eg thunderbird on first login after migration notices the folder structure has changed & automagically redownloads folders & emails. However I have noticed some really strange messages in the logs which seems to be related to customers running outlook on macos. When they login after migration they are generating commands like: dovecot: imap(xxxx): Mailbox created: INBOX 1 1 1 1 1 dovecot: imap(xxxx): Mailbox created: INBOX 1 1 1 1 1 1 dovecot: imap(xxxx): Mailbox created: INBOX 1 1 1 1 1 1 1 dovecot: imap(xxxx): Mailbox created: INBOX 1 1 1 1 1 1 1 1 dovecot: imap(xxxx): Mailbox created: INBOX 1 1 1 1 1 1 1 1 1 dovecot: imap(xxxx): Mailbox created: INBOX 1 1 1 1 1 1 1 1 1 1 dovecot: imap(xxxx): Mailbox created: INBOX 1 1 1 1 1 1 1 1 1 1 1 dovecot: imap(xxxx): Mailbox created: INBOX 1 1 1 1 1 1 1 1 1 1 1 1 ... this goes on a long time and we've not yet found a solution other than delete the imap config on their outlook and reconfigure. Does anyone have any idea why this might be happening, or if there is a way we can somehow have old namespaces for old customers, new namespaces for new customers (we are using sql login code so should be possible to do something like this in theory I think?) Thanks, Mark

[Dovecot] Getting Postfix Admin's DB to work with Postfix's/Dovecot's MySQL DB
by Femi Ajayi 18 May '12

18 May '12

Hi all, I followed the instructions here: http://library.linode.com/email/postfix/dovecot-mysql-centos-5 to configure Postfix to work with MySQL and Dovecot before discovering PostfixAdmin (I was searching for a visual tool for creating users). Since I had created MySQL database already for virtual domains and user mailboxes (following the instructions I linked to earlier) and PostFix admin's db too does the same. Question #1: is there anyway to make all these work with together for the creationg and use of virtual users/mailboxes? or is there another visual tool for creating virtual users/mailboxes? I had also installed Roundcube following the instructions on Roundcube's page: http://trac.roundcube.net/wiki/Howto_Install The questions now is: . #2. Roundcube came with its own database, which also stores user information. Is there a way to ensure that the user information is picked from the database created to work with Postfix (and not Roundcube's)? Thanks.

[Dovecot] Error in dovecot 2.0.13: "Too many levels of symbolic links"
by Tom Pawlowski 17 May '12

17 May '12

Hi all, I've run into an issue we have with dovecot versions 2.0.12 through 2.0.14 on latest CentOS 6.2 when dealing with Maildirs located on NFS partitions. Although I saw Mr. Egbert's thread, his resolution does not work on our end. When dealing with users with over 500 messages in any of their Maildir folders, they occasionally receive an error from the server: Internal error occurred. Refer to server log for more information. The corresponding log entries: dovecot: imap(user1): Error: readdir(/u1/user1/Maildir/.AUTO-DELETED-SPAM/new) failed: Too many levels of symbolic links dovecot: imap(user1): Error: readdir(/u1/user1/Maildir/.logwatch/new) failed: Too many levels of symbolic links dovecot: imap(user2): Error: readdir(/u2/user2/Maildir/cur) failed: Too many levels of symbolic links dovecot: imap(user2): Error: readdir(/u2/user2/Maildir/.Trash/new) failed: Too many levels of symbolic links dovecot: imap(user3): Error: readdir(/u1/user3/Maildir/.Trash/new) failed: Too many levels of symbolic links dovecot: imap(user3): Error: readdir(/u4/user3/Maildir/.AUTO-DELETED-SPAM/new) failed: Too many levels of symbolic links dovecot: imap(user4): Error: readdir(/u1/user4/Maildir/.AUTO-DELETED-SPAM/new) failed: Too many levels of symbolic links dovecot: imap(user4): Error: readdir(/u1/user4/Maildir/new) failed: Too many levels of symbolic links A 'find . -type l' shows there are absolutely no symbolic links to be found in those directories. Running readdir.c that Timo provided always returns errno == 0 on {cur,new} of all the directories reported in the logs. It does not occur consistently in production, but it does tend to occur to a fuzzy set of the same users on different partitions. We can replicate it every time in testing. The file count in these directories are all over the place, from less than a thousand to multiple thousands. However, it's hard to calculate what may have been in new prior to the clients processing/sorting that mail. It may have been more on the higher side than lower. The error tends to favor new over cur, but there are exceptions. The tests we have been trying: Create a new folder using alpine, save anywhere from 1000 to 10000 identical emails to the new folder. Change to that new folder, thus prompting the move from new to cur. The client receives the message and aborts the opening. Anywhere from 400-520 files are successfully moved each time. It takes numerous attempts to finally move all the files over--which I suspect some IMAP clients do, hence the inconsistent errors in production. We then create a brand new folder with the same amount of files and verify that the error is reproduceable--which it is. I'm leaning towards some sort of bug on the NFS client level, as Timo mentioned, but the odd thing is we were running this setup since early April and did not begin seeing these errors until early May--with user load being relatively consistent during that time. I would think the bug would have been evident before then. I'm also curious as to why dovecot is getting an ELOOP error code from it. Any ideas or pointers would be appreciated, sorry for the length. :) -- Tom Pawlowski OIT-CSS System Administrator office: Hill 145 email: tompru(a)jla.rutgers.edu phone: (732) 445-2634

[Dovecot] Migration between namespaces breaks outlook on mac's
by Mark Zealey 17 May '12

17 May '12

Hi there, We're running dovecot 1.1 on one set of servers with a courier-imap-like namespace configuration: namespace private { separator = . prefix = INBOX. inbox = yes } We're now migrating customers onto a dovecot-2 platform, switching from Maildir to sdbox (using dsync mirror) & changing the namespace at the same time. New namespace configuration looks like (as taken from http://wiki2.dovecot.org/Namespaces) # This is for courier-imap namespace compatability namespace { type = private separator = / prefix = inbox = yes } namespace { type = private prefix = INBOX. separator = . inbox = no hidden = yes list = no alias_for = } For 99% of clients this works fine eg thunderbird on first login after migration notices the folder structure has changed & automagically redownloads folders & emails. However I have noticed some really strange messages in the logs which seems to be related to customers running outlook on macos. When they login after migration they are generating commands like: 2012-05-07T00:04:43+01:00 imap-03 dovecot: imap(xxxx): Mailbox created: INBOX 1 1 1 1 1 2012-05-07T00:05:38+01:00 imap-03 dovecot: imap(xxxx): Mailbox created: INBOX 1 1 1 1 1 1 2012-05-07T00:06:44+01:00 imap-03 dovecot: imap(xxxx): Mailbox created: INBOX 1 1 1 1 1 1 1 2012-05-07T00:07:33+01:00 imap-03 dovecot: imap(xxxx): Mailbox created: INBOX 1 1 1 1 1 1 1 1 2012-05-07T00:08:42+01:00 imap-03 dovecot: imap(xxxx): Mailbox created: INBOX 1 1 1 1 1 1 1 1 1 2012-05-07T03:09:00+01:00 imap-03 dovecot: imap(xxxx): Mailbox created: INBOX 1 1 1 1 1 1 1 1 1 1 2012-05-07T03:09:08+01:00 imap-03 dovecot: imap(xxxx): Mailbox created: INBOX 1 1 1 1 1 1 1 1 1 1 1 2012-05-07T03:10:09+01:00 imap-03 dovecot: imap(xxxx): Mailbox created: INBOX 1 1 1 1 1 1 1 1 1 1 1 1 ... this goes on a long time and we've not yet found a solution other than delete the imap config on their outlook and reconfigure. Does anyone have any idea why this might be happening, or if there is a way we can somehow have old namespaces for old customers, new namespaces for new customers (we are using sql login code so should be possible to do something like this in theory I think?) Thanks, Mark
