[Dovecot] cluster with dsync mirror
by Bryan Vyhmeister 17 Aug '10

17 Aug '10

I have an idea for running a pair of redundant dovecot mail servers that may be odd but it might work. I'm interested in any thoughts on the topic. Would it work to run 'dsync mirror' every minute against either mdbox or sdbox mailbox on a dedicated network connection between two (or potentially three or four) mail servers? I'm trying to avoid using a NAS/SAN or some other dedicated NFS server in a simple environment with a limited number of users. Everything else about the systems could be identical. Both could receive mail using Postfix with dovecot LDA. Thank you. Bryan

However I am going to rename the package to dovecot2 in order to separate it from dovecot 1.x installs. My idea there is to allow the user to continue with the dovecot 1.x line in the event of patch updates and further releases from that tree ( like dovecot 1.2.13 ) while also maintaining the ver 2.x family. However I don't think I'll support multiple instances of dovecot ( regardless of version ) in the same Solaris zone.

[Dovecot] Split number of imap-login and pop3-login processes
by Mischa Peters 16 Aug '10

16 Aug '10

Hi All, Is there a way to define the number for imap-login processes and pop3-login processes separately? My mail server is getting more IMAP clients and much less POP3 clients these days and it continues to run out of authentication processes. I have been increasing login_max_processes_count the last couple of days and I noticed that it's split between IMAP and POP3. All 129 imap-login processes are tied up while there are only 3 of the 129 pop3-login processes in use. Any help would be greatly appreciated! Thanx!!

[Dovecot] Address book for 2.0?

With The dict {} and expire-related parts commented out, operation has no errors or delays; performance is exceptional with maildir, quota, sieve, and managesieve. I don't think managesieve would patch any part of the dictionary code as it only has to do with another service process, not a plugin; if the patching was to cause problems with other services, for the service definition coding, the other services would have a problem, correct? The expires dictionary mysql table was being correctly used, with one day of use, as there are 10000 records; I'm going to have to revise the mysql indexes for performance in case I am able to fix the dictionary problem. We like the 1.2.13 version of dovecot, as far as security, and wonder how I can find a correct defintion scripting for the dict {}, from a previous version, and merge. We are use to windows compilations. I am skeptical to go to dovecot 2.0 as our services are in production and 2.0 is beta. I have recompiled several times with fresh sources of dovecot 1.2.13, managesieve 0.11.11 patchl, and sieve 1.0.17 as directed by the Dovecot Wiki. Jerrale G, SCA

Unless release critical bugs are reported, I'll update the version number to v2.0.0 on Monday morning without any other changes. Since rc5 there have been mainly some small fixes and some error message improvements. The only (somewhat) important fixes are: - dict quota didn't always decrease quota when messages were expunged - Shared INBOX wasn't always listed with FS layout

I added some new filters to this list that will bounce your mail if it doesn't like it. If you think your bounced mail was legitimate, let me know and I'll look at fixing the scripts.

[Dovecot] Maildir over NFS
by CJ Keist 14 Aug '10

14 Aug '10

I'm working on bring up a new mail server to replace our current one. Our current mail server is running dovecot 1.1.16, with postfix using mbox format. User inboxes are stored locally on the mail server and all other mail folders in users home directory under mail which is NFS mounted on the mail server. For our new mail server I'm looking to switch to the Maildir format. Some years ago I remember reading that it was not recommended to run Maildir format over NFS. Now I'm looking at several posts that seem to indicate that Maildir should run fine over NFS. I'm a little concerned about running Maildir over NFS, especially from the howto conversion pages I read would move all messages over to the User ~/Maildir folder including the inbox. So having every single mail transaction going over NFS doesn't seem the smart thing to do. So question I have for the dovecot team, does running Maildir over NFS work well? Or would you recommend that all user mail folders be stored locally on the mail server when using Maildir? We have about 3400 users, doing about 30k mail deliveries daily. Some users have 10's of thousands of mail messages in hundreds of mail folders. Thanks... -- C. J.

[Dovecot] quota_warning bug?
by jeroen＠intuxicated.org 13 Aug '10

13 Aug '10

Hi, Today I was testing with dovecot 2.0 rc5 and experienced some odd behaviour with quota_warning rules. It's reproducable. When I set a rule (this one simply writes some message to a text file) and go over quota (2 messages in this case), it works as expected. But if I restart my client, remove one message, restart my client again and remove the last message from my inbox, it executes the warning rule again. Does this sound familiar to anyone? I tested with the debian package dovecot_2.0.rc5-0~auto+8 found in rename-it.nl's repository. Thanks. Best regards, Jeroen Koekkoek

[Dovecot] hunting timeouts
by Iv Ray 12 Aug '10

12 Aug '10

Hi guys, I inherited a Dovecot 1.0.1, which I will have to upgrade, but until then I need, if possible, to resolve a timeout. - we have about 25 IMAP users - the busiest user has about 100 000 messages (Maildir) in less than 100 folders - the mail server is on HP server with server grade 2.5" HDDs in RAID 5 - the load average of the server is low (the 5/15 minute is under 0.20) - the mail server is in-house on Gigabit Ethernet The timeout we face is that sometimes even small messages take 20-40 seconds to open (i. e. Tunderbird 2 on Windows 7). Or connection to the mail server timeouts. Could you give me a few tips where can I look in order to detect the possible reason for these timeouts. Thank you, Iv

[Dovecot] moving mail from private inbox to public folder kills the latter
by Tamas Kadar 12 Aug '10

12 Aug '10

Hi I've ran into something rather nasty: if a user moves a mail from its inbox to a public folder, the folder becomes inaccessible for others, because the moved file will have the the permission 600 instead of 777 (or 666) which the rest of the emails have in the folder. How can I change this behavior so when he moves the mail it automatically becomes world-readable? Also why one mail kills the whole folder? Here's the error I get: Error: open(/home/_shared/projects/.Long.Folder/cur/1281535484.M3B5A7P15183Q0.mail_espell_com:2,Sb) failed: Permission denied (euid=1000(ktamas) egid=1000(ktamas) missing +r perm: /home/_shared/projects/.Long.Folder/cur/1281535484.M3B5A7P15183Q0.mail_espell_com:2,Sb, euid is not dir owner) Thanks and best regards Tamas

[Dovecot] More than one private namespace not possible
by Jan Friedrich 12 Aug '10

12 Aug '10

Hi everyone, Two days ago I migrated from Courier to Dovecot 1.2.13. Everything went smooth until the point I wanted to try some more features of Dovecot. My working configuration contains just the one INBOX. private namespace. Adding any other private namespaces (e.g. SHARE. with the configuration below) produces strange results in Thunderbird 3.0.6 and Evolution 2.28.3: I cannot see the SHARE. namespace but the mail clients create SHARE^^Trunk and other funny things inside the INBOX. namespace (inside die INBOX. Maildir). Changing the name of this private namespace has no effect. Because the devault dovecot.conf tells me I need an default namespace I created one but that did not change anything. In Thunderbird 3.0.6 the namespaces are correctly displayed in the advanced IMAP settings under "private namespaces" but not in the main view. The logs do not show any errors or warnings and the Maildir for the SHARE. namespace is correctly created by Dovecot. System: Ubuntu Hardy with self-compiled Dovecot 1.2.13 with managesieve 0.11.11 patch.

[Dovecot] v2.0.rc5 released
by Timo Sirainen 12 Aug '10

12 Aug '10

http://dovecot.org/releases/2.0/rc/dovecot-2.0.rc5.tar.gz http://dovecot.org/releases/2.0/rc/dovecot-2.0.rc5.tar.gz.sig Unfortunately v2.0.0 has to be delayed a while longer, because I found that there were still problems in plugin hook handling when using more than 2 plugins. Hopefully it's now finally fully fixed, but I'd like to be sure and wait for one more week to see if people can find a problem with some plugin combination. - Using more than 2 plugins could have caused broken behavior (more fixes for this) - Listescape plugin fixes - mbox: Fixed a couple of assert-crashes - mdbox: Fixed potential assert-crash when saving multiple messages in one transaction.

[Dovecot] sessions accounting and monitoring
by Xavier Pons 12 Aug '10

12 Aug '10

Hi, we would have some accounting/monitoring of pop and imap sessions in our dovecot servers, which are the 'best' and fair way to do it? using some post-login scripts, parsing the log file, using netstat ... I know in the 2.0 version exists the doveadm who, but only relates to imap sessions... some recommendations? thanks Xavier

[Dovecot] Thunderbird IMAP woes
by Tamas Kadar 11 Aug '10

11 Aug '10

Hi, I'm a new dovecot user. We've actually just migrated our email system from Courier-IMAP to Dovecot (2.0 rc5) cause we were choking on IO and resources, and dovecot's cache and indexing really seems to help, not to mention the awesome amount of options, tweaks, and extra features, so far, I'm lovin' it. However, we're having a few issues with Thunderbird and I wonder if anyone could help. I know it's probably not dovecot's fault (some issues we already had with Courier...) but maybe some tweaks or settings could help. So here it goes: We have about 40 users, with their own mailboxes. About half of them have access to a HUGE public folder with many many subfolders (think 60 GB of email in Maildir format), it's organized into divisions and clients and projects (and subprojects and whatnot). We have ACLs controlling the public folder's access (courier-acl file). It goes like this, for a typical user that has access to the public part: - Inbox - Drafts - Trash - Sent - Some important folter - Some other important folder + SHARED |-- Finances |--|-- PriceWaterhouseCooper |--|-- ErnestandYoung |--|--|-- First project |--|--|-- Second project |--|-- Deloitte |--|--|-- Some project |--|--|-- Super important project |-- Health Care |-- Automotive |-- IT |--|-- Microsoft |--|--|-- That Windows 8 project |--|-- IBM |--|--|-- Reviving OS/2 project |--|--|-- What's eComStation project |--|-- HP (not the actual structure, but a very close analogy to what we have here) So yeah, a public folder with lots of subfolders, sub-subfolders, sub-sub-sub-subfolders, sub-sub-sub-sub-subfolders... Now, the problem is that to a lesser extent, Thunderbird 2, and to a larger extent Thunderbird 3 is having serious issues when I go (want to go) deeper than two levels of nesting. Like, in the Subscribe dialog sometimes I see the third level subfolders, sometimes I dont. If is subscribe to a second-level folder, then create a subfolder in it, the other subfolders suddenly appear. It's all very random, unfortunatelly, then only way I can use the system right now is to uncheck 'Show subscribed folders only' in Account Settings, and even then, sometimes folders disappear or reappear that are highly nested. Other clients seem to work fine, but we like Thunderbird cause of the add-ons, for example. Output of dovecot -n: # 2.0.rc5: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 2.6.26-2-xen-amd64 x86_64 Debian 5.0.5 auth_mechanisms = plain login disable_plaintext_auth = no listen = * mail_location = ~/Maildir mail_plugins = acl maildir_very_dirty_syncs = yes namespace { inbox = yes location = prefix = separator = . type = private } namespace { location = maildir:/home/_shared/projects:INDEX=~/Maildir/_shared prefix = shared. separator = . subscriptions = no type = public } passdb { driver = pam } plugin { acl = vfile } protocols = imap pop3 service imap-enable-acl-groups { executable = script-login /home/enable_acl.sh user = root } service imap { executable = imap imap-enable-acl-groups } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } verbose_proctitle = yes protocol imap { mail_max_userip_connections = 10 mail_plugins = $mail_plugins imap_acl } Thanks for the help in advance, and keep up the good work, Tamás Kádár

I've setup Apache 2.2.9 for SOGo 1.3.2 on Debian 5.0.5. I know that the developers of Debian 5.0.5 are sometimes making choices which are not handy.

[Dovecot] Subscription to folders and subscription file
by Fabio Ferrari 11 Aug '10

11 Aug '10

Hello, I'm using dovecot 1.0.7 and have a problem with subscription files. The documentation says that this file ("subscriptions" or ".subscriptions" in the root of the maildir, I've tried both) holds the informations about the subscribed folders. I've created such a file with these lines: Trash Sent Drafts INBOX.prova INBOX.prova4 And configured a client (Thunderbird) with INBOX.prova and INBOX.prova3 subscribed. So, I have 2 different configurations: one for the client and one for the server. Then, I turned off the first PC and configured with default options a second client in a second PC. I expected that - it subscribed with the entries in the subscriptions file or - it subscribed with a default option, that is All Folders or None But it subscribed exactly the entries subscribed by the first client in the first PC. So, since I grepped "prova3" on all the directory structure and I found nothing, I think that dovecot is saving these informations in a binary format somewhere. Is it right? And, if it is right, how can I configure it to use the "subscriptions" file (or any other text file) as said in the documentation? Maybe I have to upgrade dovecot to do this? thank you in advance Fabio Ferrari

Hi all, is it possible to install/activate a "out of office" messages for each user in dovecot? I've read about the Sieve scripts, but can't find a howto to install it on your dovecot 1.0.7 installation. http://wiki.dovecot.org/LDA/Sieve ... With v1.1 it's possible to include other Sieve scripts in your script ... I know, its an old release, so don't treat me like a dog ;-). Upgrade to the newest version will be done at the next maintenance windows. many thanks Richard

[Dovecot] Outlook 2003 Client
by Richard Gliebe 11 Aug '10

11 Aug '10

Hi all, my dovecot IMAP Server (1.0.7-7.el5) is now up and running ;-) Now I want that all clients have to save there sent messages in the IMAP folder on the server. no problem with the thunderbird clients. BUT, I can't configure the office 2003 clients to save there send messages to the imap folder. Some people told me, that outlook 2003 isn't able to do that. The send messages folder have to be a "local" folder and not a folder on the IMAP server. I can't believe. The only way on outlook 2003 is to create a messages filter .... very strange .... many thanks Richard

[Dovecot] dot-containing foldernames \HasNoChildren bug ?
by Samuel Kvasnica 11 Aug '10

11 Aug '10

Hello, we experience problems with dovecot configuration using the listescape plugin to allow dots in foldernames. In some mail clients, dot-containing folders won't show any subfolders. This seems to be related to the fact that the \HasNoChildren flag is set on such folders even if subfolders do exits. Here is an example from telnet session: * LIST (\HasNoChildren) "/" "my.test" * LIST (\HasNoChildren) "/" "my.test/aaa" * LIST (\HasNoChildren) "/" "my.test/folder.first" * LIST (\HasNoChildren) "/" "my.test/folder.first/sub.sub.folder" * LIST (\HasNoChildren) "/" "my.test/folder.second" when we rename my.test to my_test everything works as expected: * LIST (\HasChildren) "/" "my_test" * LIST (\HasNoChildren) "/" "my_test/aaa" * LIST (\HasNoChildren) "/" "my_test/folder.first" * LIST (\HasNoChildren) "/" "my_test/folder.first/sub.sub.folder" * LIST (\HasNoChildren) "/" "my_test/folder.second" Could somebody look into this issue or give us some more debugging hints ? We use dovecot 1.2.13 + maildir + acl+quota+listescape, the config is: # 1.2.13: /etc/dovecot/dovecot.conf # OS: Linux 2.6.31.13-18-xen x86_64 openSUSE 11.2 (x86_64) xfs base_dir: /var/run/dovecot/ log_path: /var/log/dovecot protocols: imap imaps managesieve ssl: no 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(managesieve): /usr/lib/dovecot/managesieve-login login_processes_count: 5 mail_privileged_group: vmail mail_uid: vmail mail_gid: vmail mail_location: maildir:/data/vmail/%u/Maildir mail_debug: yes mail_executable(default): /etc/dovecot/gmember.sh mail_executable(imap): /etc/dovecot/gmember.sh mail_executable(managesieve): /usr/lib/dovecot/managesieve mail_plugins(default): fts fts_squat acl imap_acl quota imap_quota listescape mail_plugins(imap): fts fts_squat acl imap_acl quota imap_quota listescape mail_plugins(managesieve): mail_plugin_dir(default): /usr/lib64/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib64/dovecot/modules/imap mail_plugin_dir(managesieve): /usr/lib64/dovecot/modules/managesieve namespace: type: private separator: / inbox: yes list: yes subscriptions: yes namespace: type: shared separator: / prefix: Shared/%%u/ location: maildir:/data/vmail/%%u/Maildir:INDEX=/data/vmail/%u/index/shared/%%u list: yes namespace: type: public separator: / prefix: Public/ location: maildir:/data/vmail/Public:CONTROL=/data/vmail/%u/index/public:INDEX=/data/vmail/%u/index/public list: yes lda: postmaster_address: postmaster(a)xxx.co.at hostname: imap mail_plugins: acl sieve quota listescape mail_plugin_dir: /usr/lib64/dovecot/modules/lda log_path: /var/log/dovecot-deliver-errors.log info_log_path: /var/log/dovecot-deliver.log auth_socket_path: /var/run/dovecot/auth-master auth default: mechanisms: plain login user: vmail master_user_separator: # passdb: driver: passwd-file args: /etc/dovecot/dovecot.deny deny: yes passdb: driver: passwd-file args: /etc/dovecot/passwd.masters master: yes passdb: driver: ldap args: /etc/dovecot/dovecot-ldap_pass.conf userdb: driver: ldap args: /etc/dovecot/dovecot-ldap_user.conf 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 plugin: quota: maildir quota_rule: *:storage=16G quota_rule2: Trash:storage=100M quota_rule3: Junk:ignore quota_warning: storage=85%% /etc/dovecot/quota_warning.sh 85 %u quota_warning2: storage=90%% /etc/dovecot/quota_warning.sh 90 %u quota_warning3: storage=95%% /etc/dovecot/quota_warning.sh 95 %u acl: vfile:/etc/dovecot/acls:cache_secs=300 acl_shared_dict: file:/var/lib/dovecot/shared-mailboxes.db sieve: /data/vmail/%u/.dovecot.sieve sieve_dir: /data/vmail/%u/sieve fts: squat fts_squat: partial=4 full=7

[Dovecot] Thunderbird namespace handling
by Thomas Hummel 10 Aug '10

10 Aug '10

Hello, I've noticed that Thunderbird (3.0.3) seems to wrongly "repeat" the namespace prefix when selecting the top level maildir of a namesapce. It doesn't occur if "list=yes" and TB has no clue about the namespace prefix. But it seems to happen only when TB is aware of the namespace prefix, either via the NAMESPACE command (so in "hidden=no" setups) or via hard setting it up in the "Account Settings". For instance, if location = maildir:/courriel/boites/test:CONTROL=/courriel/meta/test hidden = no list = yes Trying to select the mailbox which appears as "#test" in the UI gives 4 select "#test/#test" in rawlogs, giving for the user a "Mailbox doesn't exist" error, whereas, via telnet, I can : x select "#test" * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 2 EXISTS * 0 RECENT * OK [UIDVALIDITY 1271768576] UIDs valid * OK [UIDNEXT 3] Predicted next UID * OK [HIGHESTMODSEQ 3] Highest x OK [READ-WRITE] Select completed. The same happens with any combination of (hidden=, list=, "Allow Server to override [the namesapce] settings") where TB knows about the namespace. Any ideas ? Thanks. -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

The slapd log file is showing "deffering operation: too many executing". When i googled i have seen that if the client is not properly disconnecting the connection slapd will give this error.

[Dovecot] Why p_strdup and other string functions uses loops instead strlen? (dovecot 2.0.rc4)
by Len7hir 10 Aug '10

10 Aug '10

I did Dovecot profiling on huge e-mail system, and p_strdup was very high on list. I do minor change: p_strdup: /* for (len = 0; (str)[len] != '\0'; ) len++; len++; */ len = strlen(str) + 1; p_strndup: /* len = 0; while (len < max_chars && ((const char *) str)[len] != '\0') len++; */ len = strnlen(str, max_chars); And after changes strdup drop down on the profile list. This is output from oprofile: samples % symbol name 28000 10.9764 p_strdup 8507 3.3349 safe_memset 7857 3.0801 .plt 7627 2.9899 buffer_write 6871 2.6935 parse_body_add_block And after (about four times smaller samples, but shows everything): samples % symbol name 9595 26.2625 parse_next_body_to_boundary 8247 22.5729 parse_body_add_block 772 2.1130 .plt 672 1.8393 buffer_write 658 1.8010 __i686.get_pc_thunk.bx 614 1.6806 safe_memset 586 1.6039 pool_alloconly_malloc 559 1.5300 p_strdup 533 1.4589 hash_table_insert_node I wonder why You use loops instead strlen, which is optimalised on every platforms.

[Dovecot] maildirsize having incorrect content, how to recreate/correct?
by Thomas von Eyben 10 Aug '10

10 Aug '10

Hi List, I have (otherwise successfull) migrated a server from cyrus to dovecot (Mac OS X Server 10.5.8 to 10.6.4 [dovecotd version to be 1.1.20apple0.5]). There are ca. 300+ users of which a very small handfull (ca. 1 %) are having reported a usage size that is very different to what 'du' reports. How can I rebuild the maildirsize and why might it be wrong in the first place(?) Will the maildirsize files be regenerated if deleted and when will this then happen ( at the next time of the user logging in or…) >From what I can read here: http://www.inter7.com/courierimap/README.maildirquota.html The maildirsize file contains (in linenumber > 1) "bytecount SPACE filecount" I also have one (perhaps more) user with one line having a negative value in maildirsize (-138204393 -2294) how can that happen / be corrected?

Hello, what does the Dovecot process ssl-build-param do? It has just eaten all my CPU for a minute or so. When I run it myself with "--help", it just does it all again and says "SSL parameters regeneration completed".

[Dovecot] network_biopair_interop
by Leander S. 09 Aug '10

09 Aug '10

Hi, since I use TLS I'm getting the following waning when I send mail to somebody in the internet:| "warning: network_biopair_interop: error reading 5 bytes from the network: Connection reset by peer|" ... Mail seems to be delivered & sent as usual. I found a post about it: http://de.postfix.org/pipermail/postfix-users/2009-March/000891.html but it didn't help to involve: "smtpd_tls_ask_ccert=no" Did anybody face that issue before? I'm using self signed certs. Regards

[Dovecot] restricting access by reverse domain name
by Phil Howard 09 Aug '10

09 Aug '10

Is there a feature or plugin to restrict access to IMAP/POP service by the domain name in reverse lookup? It would be even better if this restriction can exclude certain users (e.g. some users can access IMAP from certain networks but other users cannot). -- sHiFt HaPpEnS!

[Dovecot] Dovecot 2.0.rc4 not generating ssl-parameters.dat on first start
by Andreas M. Kirchwitz 09 Aug '10

09 Aug '10

Dear Dovecot lovers! When starting Dovecot 1.x the first time, it runs "ssl-build-params" to generate a file named "ssl-parameters.dat". This takes a couple of minutes. During this time users have no access to their mail, but this can be planned in advance and users can be notified. This is explained in http://wiki.dovecot.org/SSL/DovecotConfiguration With Dovecot 2.0.rc4, the new command "ssl-params" seems to do this job, but unfortunately it isn't run on first start of Dovecot but the start is delayed until a user connects to port 993 (or does STARTTLS in 143). According to http://wiki2.dovecot.org/SSL/DovecotConfiguration it should behave the same way as Dovecot 1 did. So, with Dovecot 2.0.rc4 it hits the first user who wants to establish a secure connection. It's hard to explain this to users. ;-) Of course, I could simply run "telnet <imaphost> 993" manually after installation. I also tried running "ssl-params" manually before starting Dovecot but it stays in foreground forever and doesn't seem to finish (what is it waiting for?) So it would be really great if Dovecot 2 could do this on its own like Dovecot 1 did. Besides that, Dovecot 2.0 runs like a charm ... Andreas

[Dovecot] IMAP namespace and Courier migration
by Yves Goergen 09 Aug '10

09 Aug '10

Hello, the migration guide from Courier-IMAP to Dovecot says that I should change the folders namespace to "INBOX." if I want a seamless migration. Isn't it that e-mail clients determine that namespace automatically? At least I never needed to enter one in Thunderbird and then it was there. What happens if I copy the database, all the Maildir files, run the migration script to convert the special files and don't change that namespace - will clients show an error message and stop working or will it still work? -- Yves Goergen "LonelyPixel" <nospam.list(a)unclassified.de> Visit my web laboratory at http://beta.unclassified.de

[Dovecot] Dovecot 2.0.rc4 core dumped with Alpine 2.00
by Andreas M. Kirchwitz 09 Aug '10

09 Aug '10

Hi Timo and all others! The current Dovecot 2.0.rc4 did really well with Mutt 1.5.20 and Thunderbird 3.1.2, but a user with Alpine 2.00 crashed it immediately. I'm running Fedora 13 (Linux) and compiled Dovecot 2.0.rc4 manually like I did before with Dovecot 1.2.13. When switching from 1.2 to 2.0 I removed all those ".imap" folders with internal cache data (didn't know for sure if it's compatible between both version). All folders are in mbox format. When Alpine is started, the first crash happens. Alpine notifies the user that there was a problem connecting the IMAP server. No mail is display. And then the second crash happens. Looks like Alpine starts a second try to connect to the IMAP server before displaying the (empty) screen with (no) folders.

[Dovecot] Dovecot and Active Directory separate domain data stores.
by Andrew Bruce 09 Aug '10

09 Aug '10

Hi, I've got Dovecot setup to auth my AD users fine via Winbind and I've also tried it using LDAP and can get this working also. The problem lies in the way we store our email for our virtual users in this setup. We run a flat domain for AD (lets call it newzealand.local), and then under each users account that gets email, in the E-mail field in AD, they have an email address like user1@auckland, user2@wellington, user3@chch and so on. With Postfix, I've set it up so that each email domain ends up being stored in a different path - /mail/auckland/user1, /mail/wellington/user2, /mail/chch/user3. This was done using a query filter that returned a person's email address from AD, chopped it into separate user/domain parts around the '@' symbol and using these to determine where the mail should be stored. This seems to work well for our purposes. But now I need to get Dovecot to be able to do the same thing in order to present the email to the user. I'm fairly certain this isn't going to work with Winbind, so I implemented the LDAP passdb and got that working, but I can't seem to quite work out how to get it to work with the domain part from the email address. Could someone give me a pointer in the right direction if this is possible. I'm thinking it has to do with the user_attrs variable, but can't quite workout how I would split this. Or is there a better way to do this? Thanks, Andrew

[Dovecot] Setting up webmail in DMZ
by Phill Edwards 09 Aug '10

09 Aug '10

I have a Smoothwall server on my network and am running three network interfaces off it. 1) local LAN 192.168.0.0 with PCs and an internal dovecot server on 192.168.0.154. 2) internet interface 3) DMZ 192.168.2.0 which has a linux web server 192.168.2.1 on which I want to install a webmail so I can access my email remotely. Originally 192.168.2.1 couldn't see the 192.168.0.0 network but with some help from the Smoothwall forums I have fixed that. The problem now is that 192.168.2.1 can't connect to the dovecot server on 192.168.0.154. When I "telnet 192.168.0.154 993" or "telnet 192.168.0.154 143" I get a "Connection refused" error. But these commands work fine from PCs on the 192.168.0.0 network. I'm pretty sure there's no firewall on the dovecot server and /etc/hosts.allow and /etc/hosts.deny are empty. Is there a default setting that I need to change in Dovecot that only allows connections from machines on the same subnet?

[Dovecot] Searching dovecot Maildir

Hi All, Loving Dovecot after several years with Cyrus. This might be more a general question, but this seemed the best place to ask. The idea is to just add up all the values of quotes I've sent in a month. I want to search my Sent mail folder for all messages with a certain subject, then "grep" out a certain line that has a dollar ($) figure, and add up those figures. The idea is to just add up all the values of quotes I've sent in a month. Can it be done? Any help appreciated. regards, Murray Dovecot 1.2.6

[Dovecot] Strange behaviour when add new mailbox to IMAP (v 1.2.13)
by Alexander Chekalin 06 Aug '10

06 Aug '10

Hi, I think I need to ask you for advice. Personally I face that for the first time and hardly imagine this could be possible at all, but... My setup is simple: I have one mail server where all of my mail accounts are stored, and another one to store backup of all mailings. The scheme is simple, SMTP on first server forwards a copy of each message to address catchall(a)secondserver.my-domain. So whenever I need to restore any message I'll simple search for it on second server. Both servers are have Dovecot 1.2.13 as IMAP servers. First server's Dovecot is sql-backed one, the second server's (in fact it serving just one box) is using passwd-style text file auth. Other than this, setup is pretty similiar, and everything is well, but here is the mystery: I use Thunderbird (yesterday it was 3.1.1 and now it is 3.1.2) as my IMAP client. When I connect to my IMAP account on second server, and create mailbox, I see that there appears greyed folder named #virtual^Sent , and my new mailbox is in it. When I do the same thing on first server, everything works just as I expect it (new mailbox created right under root of my IMAP account). If I create on second server new mailbox right under any existing (say, under Inbox) everything is fine also. To check the problem I simplified my Dovecot config to the bare minimum, and it also won't work (#virtual^Sent still there). When I see on server disk, I see there .#virtual^Sent.NewTestMailbox dir (NewTestMailbox is the test mailbox I created), but there is no .#virtual^Sent dir. I rebuilt Dovecot, and also tried to build 1.2.12, none worked. May there be any solution for that? Yours, Alexander Chekalin

[Dovecot] Problem creating sockets after Solaris Live Upgrade
by Jürgen Obermann 06 Aug '10

06 Aug '10

Hello, I use Solaris Live Upgrade to install solaris patches in an alternate boot environment. Unfortunately the dovecot sockets /opt/local/var/run/dovecot/dict-server and /opt/local/var/run/dovecot/login/default are created as normal files in the ABE. After switching to the ABE dovecot will not start because of the existence of these two files. After removing these files dovecot starts normally. I think that dovecot should create the sockets even if there exist files with the same names. Here is the protocol of this: Dovecot uses two sockets in the running system: # ls -al /opt/local/var/run/dovecot/login/default /opt/local/var/run/dovecot/dict-server srwxrwxrwx 1 root root 0 Aug 4 10:07 /opt/local/var/run/dovecot/dict-server srw-rw---- 1 root dovecot 0 Aug 4 10:07 /opt/local/var/run/dovecot/login/default In the Alternate Boot Environment created with Solaris Live Upgrade there are normal files instead of the sockets: # ls -al /a/opt/local/var/run/dovecot/login/default /a/opt/local/var/run/dovecot/login/default -rw-rw---- 1 root dovecot 0 Jul 7 17:01 /a/opt/local/var/run/dovecot/login/default -rw-rw---- 1 root dovecot 0 Jul 7 17:01 /a/opt/local/var/run/dovecot/login/default During booting this ABE dovecot will not start, unless both files are removed: Aug 6 06:55:30 hostname dovecot: Fatal: Socket already exists: /opt/local/var/run/dovecot/dict-server # ls -al /opt/local/var/run/dovecot/dict-server -rwxrwxrwx 1 root root 0 Aug 4 10:09 /opt/local/var/run/dovecot/dict-server # rm /opt/local/var/run/dovecot/dict-server # /etc/init.d/dovecot start Last died with error (see error log for more information): Socket already exists: /opt/local/var/run/dovecot/dict-server Aug 6 06:57:50 hostname dovecot: [ID 583609 local0.info] Dovecot v1.2.12 starting up Aug 6 06:57:50 hostname dovecot: [ID 583609 local0.error] net_listen_unix(/opt/local/var/run/dovecot/login/default) failed: Address already in use Aug 6 06:57:50 hostname dovecot: [ID 583609 local0.crit] Fatal: Couldn't create auth process listener # ls -al /opt/local/var/run/dovecot/dict-server srwxrwxrwx 1 root other 0 Aug 6 06:57 /opt/local/var/run/dovecot/dict-server # ls -al /opt/local/var/run/dovecot/login/default -rw-rw---- 1 root dovecot 0 Aug 4 10:09 /opt/local/var/run/dovecot/login/default # rm /opt/local/var/run/dovecot/login/default # /etc/init.d/dovecot start # ls -al /opt/local/var/run/dovecot/login/default srw-rw---- 1 root dovecot 0 Aug 6 07:00 /opt/local/var/run/dovecot/login/default Both sockets are created by dovecot if they don't exist.

[Dovecot] dovecot 2.0 rc4, expire, sqlite
by Burckhard Schmidt 06 Aug '10

06 Aug '10

Hello, I will use expire like described within wiki2.dovecot.org/Plugins/Expire with sqlite for a folder AutoCleanSpam. If I copy a message (with TB) into that folder, I get an error if there exists no entry for that user and that folder within the database: dict: Error: sqlite: exec(INSERT INTO expires (expire_stamp,username,mailbox) VALUES ('1281016832','userx','AutoCleanSpam')) failed: unable to open database file (14) dict: Error: sql dict: commit failed: If I make an initial entry manually first no error occurs. Anymore there is a problem concerning acl of the base directory of the expires.db: dict: Error: sqlite: open(/addons/expire/expires.db) failed: unable to open database file dict: Error: dict sql lookup failed: out of memory It was necessary to give "other" r-x permissions for directory /addons/expire. I use mail_uid = sysdov and mail_gid = sysdov. That is uid 29. Furthermore I work with userdb ldap and uid/gid mapping: user_attrs = homeDirectory=home,uidNumber=29,gidNumber=29 So usually it was sufficient using acl like this drwxr-x--- 2 sysdov sysdov 5 Aug 5 16:00 /addons/expire As which user expire, dict, sqlite access are running? -- Regards --- Burckhard Schmidt

[Dovecot] dovecot-auth process crashed during pam login
by Elmar Rudigier 06 Aug '10

06 Aug '10

Hello! We experienced crashes of the dovecot-auth process during user verification with pam_ssh. After a little debugging I saw that pam_ssh and dovecot both provide a buffer_free() function. During cleanup of pam_ssh the buffer_free() from dovecot was called. The members of the buffer had all "out of bound" addresses. After rename the buffer_free() in dovecot the pam login works fine.

[Dovecot] Configure Dovecot to move read mails to another folder?
by Steven Weiß 06 Aug '10

06 Aug '10

Hallo, is it possible (with dovecot sieve?) to deliver incoming mails to the default INBOX and then, when I have read the mail with Thunderbird, automatically move it to another folder? I know I could create filters in my mail client. But that has the disadvantage that I would need to create these filters everywhere: on my office PC, at home, webmail, ... Also moving a mail from one folder to another marks the original mail as deleted, at least in Thunderbird. Maybe other clients finally delete the mail. Therefore that would be really cool. Another related problem for me is: how can I automatically move outgoing mails to another folder? I created sieve-rules but it doesn't work - the mails remain in the folder "sent-mail". For example: if address :domain :is "to" "somedomain.de" { fileinto "sent-mail.Somedomain"; stop; } Greetings, Steven

[Dovecot] Double logging problem
by Nikolaos Milas 06 Aug '10

06 Aug '10

Hi, I have a relatively new installation with LDAP and Postfix, running smoothly on CentOS but it logs dovecot messages both in /var/log/messages and in /var/log/dovecot.log. I have configured it to log in /var/log/dovecot.log (with syslog_facility: local1 and a respective line in syslog.conf, see below) but it also logs in /var/log/messages. As a result, I would expect it to only log into /var/log/dovecot.log. Can someone suggest why this happens and help me stop logging dovecot messages in /var/log/messages ? Could it be because the following directive (in syslog.conf) does not capture dovecot messages to exclude them? *.info;mail.none;authpriv.none;cron.none /var/log/messages Could I use something like (in syslog.conf): *.info;mail.none;authpriv.none;cron.none;dovecot.none /var/log/messages to capture dovecot messages and *exclude* them from /var/log/messages ? I am not sure if syslog understands "dovecot.none". Please explain how this could be done. Here is the configuration (I've changed real domain name with example.com) # dovecot --version 1.2.11 # dovecot -n # 1.2.11: /etc/dovecot.conf # OS: Linux 2.6.18-194.3.1.el5.centos.plus x86_64 CentOS release 5.5 (Final) syslog_facility: local1 ssl_ca_file: /etc/pki/CA/certs/cert-xxx.pem ssl_cert_file: /etc/pki/CA/certs/cert-xxx.pem ssl_key_file: /etc/pki/CA/private/key-xxx.pem 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_max_userip_connections(default): 10 mail_max_userip_connections(imap): 10 mail_max_userip_connections(pop3): 3 mail_location: maildir:~/Maildir/ mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota mail_plugin_dir(default): /usr/lib64/dovecot/imap mail_plugin_dir(imap): /usr/lib64/dovecot/imap mail_plugin_dir(pop3): /usr/lib64/dovecot/pop3 imap_client_workarounds(default): delay-newmail outlook-idle netscape-eoh imap_client_workarounds(imap): delay-newmail outlook-idle netscape-eoh imap_client_workarounds(pop3): pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh lda: postmaster_address: postmaster(a)example.com auth default: mechanisms: plain login username_format: %Lu verbose: yes debug: yes passdb: driver: ldap args: /etc/dovecot-ldap.conf userdb: driver: static args: uid=500 gid=500 home=/home/vmail/%u socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix plugin: quota: maildir:User quota quota_rule: *:storage=307200 quota_warning: storage=75%% /opt/mail.sh 75 %u # grep -v '^ *$#.*$\?$' /etc/dovecot-ldap.conf hosts = ldap.example.com tls = yes base = ou=people, dc=example, dc=com scope = subtree ldap_version = 3 auth_bind = yes pass_attrs = uid=user,userPassword=password auth_bind_userdn = uid=%u,ou=people,dc=example,dc=com pass_filter = (uid=%u) And the content of /etc/syslog.conf # cat /etc/syslog.conf # Log all kernel messages to the console. # Logging much else clutters up the screen. #kern.* /dev/console # Log anything (except mail) of level info or higher. # Don't log private authentication messages! *.info;mail.none;authpriv.none;cron.none /var/log/messages # The authpriv file has restricted access. authpriv.* /var/log/secure # Log all the mail messages in one place. mail.* -/var/log/maillog # Log cron stuff cron.* /var/log/cron # Everybody gets emergency messages *.emerg * # Save news errors of level crit and higher in a special file. uucp,news.crit /var/log/spooler # Save boot messages also to boot.log local7.* /var/log/boot.log # Dovecot messages will be using local1 local1.* /var/log/dovecot.log #local2.* /var/log/php.log local3.* /var/log/sympa.log Thanks, Nick Milas Greece P.S.

[Dovecot] Cyrus to Dovecot migration (OS X Server): Backup + restore messages, live "standby server" and delayed expunge and…
by Thomas von Eyben 05 Aug '10

05 Aug '10

Hi List, I am very close to migrating from Cyrus to Dovecot (to be more precise from Mac OS X Server 10.5.8 to 10.6.4). The latter is reporting the dovecotd version to be 1.1.20apple0.5. All I have read about dovecot is extremely positive so I am exited to make the switch. BACKUP: BUT I would like to be sure that I can make a sound backup strategy. For Cyrus i used topicdesk's mailbfr (a script that stops the mailservice and then rsync's the mailstore to a backup location incrementing daily and restarting a complete backup weekly). This script is not yet ready for Dovecot, but from what I have read it should be as easy as "just" backing up the mail-data (/var/spool/imap/dovecot/mail in OS X), eg. with rsync. Our current setup is requiring ca. 11 hours for a full (200+ GB) backup (weekly) this is not good for uptime… RESTORE: Restore should be the same (well reverse) "just" restoring the files and making sure the get the correct permissions. What I am not sure about is the (cyrus specific) need for reconstructing the database, as I have read (on this list) it seems that dovecot is designed better and will "automatically" recognised the restored messages without the need to reconstruct any databases or stopping+restarting the service. Is this really true ,-)? NB.: For restores I plan to always restore to a specific subfolder for the user (eg RESTORED MAIL) as opposed to placing the mails within the folder hierachy LIVE BACKUP SERVER I have been told, that dovecot provides clever mechanisms for making it possible to synchronise the data to a "hot-spare" server. Both for being able to provide access to the data during breakdown or planned maintenance, but perhaps also to make backups easier (perhaps not needed?) DELAYED DELETION OF MESSAGES I believe that the feature is called "delayed expunge", a way of not deleting the messages until after an additional delay from the time the user deletes the message. Is this possible in dovecot? DOCUMENTATION Where would the best FAQ/KB for getting to know dovecot better be, perhaps there have even been written good books (I know old fashioned, but I really like the physical hands on a real book provides ;-) It's a lot of questions and I hope for good pointers to where I can find more documentation and good feedback from the list.

[Dovecot] IMAP IDLE, Virtual mailboxes
by Patrick Nagel 05 Aug '10

05 Aug '10

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, K-9 Mail (on Android) has been mentioned on this list multiple times recently, I think it's definitely an IMAP client "on the rise". :) It supports IMAP IDLE, and so brings "push mail" to Android mobile phone users. To bring this into the context of this mailing list: I guess a lot of people on this list are making use of server-side filtering (using sieve), so that mails from certain persons or mailing lists end up in the right mailboxes, right on delivery. Now, this is all great, but there are issues when server-side filtering and IMAP IDLE come together: Only one mailbox can be "watched" with one IMAP IDLE connection. So, people who have set up elaborate server-side filtering with say, 50 different sieve "fileinto" calls, will constantly have a *lot* of IMAP IDLE connections open, if they really want to get informed of any mail arriving in any of their mailboxes. Keeping those 50 IMAP connections open wouldn't cost much bandwidth, and who cares about the Internet router's connection tables getting unnecessarily big, anyway? But then there is the "problem" of a mobile phone being carried around constantly, switching physical connections (from WLAN access point 1 to WLAN access point 2 to 3G to 2G to no connection at all and back), every time needing to terminate* those 50 IMAP connections, and then establish 50 new ones (with SSL handshake overhead and all). So, all in all, not an optimal solution. *) (which does not always happen the way it should, see http://code.google.com/p/k9mail/issues/detail?id=1255) I see two ways to improve the situation (one of them quite dovecot-centric): 1) A new extension of the IMAP protocol: IMAP MULTI-IDLE, which somehow allows a client to get notified of changes to more than one mailbox within one IMAP connection. This conflicts with the basic IMAP design though, AFAIK, and is thus not likely to be feasible. 2) Enhancing dovecot's Virtual plugin, so virtual mailboxes do not only get updated on select and expunge, but also when anything changes that affects the set of messages shown in the virtual mailbox. I guess that would have an impact on performance, and thus should be optional. Let me explain the second one: With the help of the Virtual plugin, it is possible to pull all those 50 mailboxes that receive incoming mail together again, just like the INBOX of the pre-server-side-filtering times - the user could configure a virtual mailbox to show all unread mails from those 50 mailboxes. Now the mobile IMAP IDLE users could just watch that one virtual mailbox, needing only one IMAP IDLE connection. After having read the mail (directly in the virtual mailbox), it would disappear, but of course still be in the "real" mailbox, determined by the sieve filter on delivery.

[Dovecot] sender address of sieve vacation script
by Wolfgang Burger 05 Aug '10

05 Aug '10

Hi, not entirerly sure wether this is the right place to ask. Sorry if not. I´m running dovecot on a Mac OS X Server (10.6.4). Everything works fine. When I try to enable a vacation message, I get the following error in the log: delays=0/0.01/0.09/0.1, dsn=5.0.0, status=bounced (host XXX[x.x.x.x] said: 553 Mail to <name(a)domain.tld> not allowed; missing domain name in MAIL FROM (in reply to RCPT TO command)) Where host is the mail relay. The logs on the mail relay show matching entries. Sending mails is generally working. I´ve sniffed the network traffic and the FROM Field in the SMTP transfer contains only the following text: <> I´ve allready set the value of myorigin in /private/etc/postfix/ main.cf but to no avail. Can somebody tell me where I can set the sender address of the vacation mail? Or is there something else wrong? Thank you very much. Best regards Wolfgang

I didn't find anything interesting in the search, so I just wanted to see what other people have done (or thought about doing). I'd like to be able to access my dovecot server via IMAP, from the Internet, using the integrated e-mail client from a smart phone. I'm very concerned about security and don't feel comfortable just poking holes into the firewall for direct access from the Internet. Is there a better way to do this?

It's much better to do this in Dovecot/LMTP then in Postfix-Relay (which can then use LMTP for dynamic address verification).

[Dovecot] Dovecot 1.2.13 intermittent authentication failures
by C. Bensend 04 Aug '10

04 Aug '10

Hey folks, I recently upgraded my mail server from an older OpenBSD -CURRENT snapshot to the latest (Aug 1). As part of this upgrade, I updated all of my packages to their latest versions. Since this upgrade, dovecot has begun failing to authenticate intermittently. I use it primarily for web mail (Squirrelmail 1.4.20) and leave myself logged in during the day. This problem manifests itself by kicking me back to the "Username or password incorrect" screen occasionally (several times an hour) when the page refreshes. I am not using sieve, and while I have the PostgreSQL version of the OpenBSD package installed, I do not currently use it for authentication. I am authenticating against the OpenBSD system. The only error I get in the mail log is: Aug 3 11:00:09 fusion dovecot: imap-login: Aborted login (auth failed, 1 attempts): user=<benny>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured There are no errors in the Apache error log... Squirrelmail's version wasn't upgraded, so I don't think this is a Squirrelmail problem as far as I can tell. My config is pretty simple: # 1.2.13: /etc/dovecot.conf Warning: fd limit 128 is lower than what Dovecot can use under full load (more than 640). Either grow the limit or change login_max_processes_count and max_mail_processes settings # OS: OpenBSD 4.8 i386 base_dir: /var/dovecot/ listen: *, [::1] ssl_cert_file: /etc/ssl/webmail.crt ssl_key_file: /etc/ssl/private/webmail.key login_dir: /var/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login login_user: _dovecot mail_location: maildir:~/Maildir mbox_write_locks: fcntl imap_client_workarounds: delay-newmail netscape-eoh tb-extra-mailbox-sep namespace: type: private prefix: INBOX. inbox: yes list: yes subscriptions: yes lda: postmaster_address: postmaster(a)example.com auth default: mechanisms: plain login passdb: driver: bsdauth userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: _postfix group: _postfix Everything seems to be working just fine (ie, I don't get any other IMAP errors or see any problems), it's just that it will spontaneously fail to authenticate. When this happens, it may take more than one try to get logged back in. I checked with the OpenBSD port's maintainer, and he hadn't heard of any similar issues (and he uses it himself). Can anyone please help? Thank you so much! Benny -- "Something's going on in this house - last night, I saw a face!" "Did it have a nose?" "Yes!"

[Dovecot] error 89 when loading plugin

Hi, I'm very confused - that's not too difficult for me. I have written a small plugin change_passwd_plugin.c I would like this custom IMAP command to be available to all users. The code contains the following. void change_passwd_plugin_init(void) { command_register("XCHANGEPASSWORD", cmd_xchangepasswd, 0); str_append(capability_string, " XCHANGEPASSWORD"); } void change_passwd_plugin_deinit(void) { command_unregister("XCHANGEPASSWORD"); } % nm 0000000000000920 T change_passwd_plugin_deinit 00000000000008ec T change_passwd_plugin_init 0000000000201248 D change_passwd_plugin_version dovecot.conf mail_plugins = change_passwd_plugin mail_plugin_dir = /usr/lib/dovecot/imap imap_capability = XCHANGEPASSWORD %ls -la /usr/lib/dovecot/imap ls -la /usr/lib/dovecot/imap total 28 drwxr-xr-x 2 root root 4096 Aug 1 16:03 . drwxr-xr-x 3 root root 4096 Aug 1 10:51 .. -rwxr-xr-x 1 root root 16969 Aug 1 16:03 change_passwd_plugin.so During login I see the following /var/log/maillog Aug 1 16:13:00 development dovecot: IMAP(test): Loading modules from directory: /usr/lib/dovecot/imap Aug 1 16:13:00 development dovecot: IMAP(test): Plugin change_passwd_plugin not found from directory /usr/lib/dovecot/imap Aug 1 16:13:00 development dovecot: child 29715 (imap) returned error 89 I don't understand why I'm getting an "error 89" reported. The login session is terminated by dovecot when the error occurs. Any assistance or ideas would be appreciated. Regards, John

[Dovecot] IMAP/POP3 Proxy Redundancy
by Cory 04 Aug '10

04 Aug '10

Looking over the list archives and Wiki there doesn't seem to be any sort of built-in host redundancy with the proxy. I would prefer to use a built in though it doesn't look like this is possible. One of the suggestions that I found in the list archives was to write a script which checks the health of the hosts and adjusts the MySQL table accordingly. Has anyone done anything like this in production? Thanks, Cory Here is a sample of what I'm testing the proxy with. CREATE TABLE `users` ( `user` varchar(255) NOT NULL, `filesystem` varchar(5) NOT NULL, PRIMARY KEY (`user`), UNIQUE KEY `idx_user` (`user`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1 CREATE TABLE `hostmap` ( `id` int(11) NOT NULL auto_increment, `filesystem` varchar(5) NOT NULL COMMENT 'Filesystem identifier', `ip` int(10) unsigned NOT NULL, `alive` tinyint(1) NOT NULL default '1', PRIMARY KEY (`id`), UNIQUE KEY `idx_hostmap` (`filesystem`,`ip`) ) ENGINE=MyISAM AUTO_INCREMENT=103 DEFAULT CHARSET=latin1 password_query = SELECT user,NULL as password, INET_NTOA(hostmap.ip) as host, 'Y' AS proxy_maybe from users left join hostmap on users.filesystem=hostmap.filesystem where hostmap.alive=1 and users.user='%u' limit 1;

[Dovecot] Dovecot 2.0.rc3 Capability response
by Christian Affolter 04 Aug '10

04 Aug '10

Hi I have a question regarding the IMAP CAPABILITY command behavior of Dovecot 2.0.rc3. While connecting to a Dovecot 1.2.4 server and requesting the supported capabilities, Dovecot returns all capabilities: * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE STARTTLS AUTH=PLAIN] Dovecot ready. a1 CAPABILITY * CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE SORT THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT IDLE CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH ACL RIGHTS=texk QUOTA AUTH=PLAIN AUTH=CRAM-MD5 a1 OK Capability completed. Doing the same on 2.0.rc3, will return only a limited set of supported capabilities: * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE STARTTLS AUTH=PLAIN] Dovecot ready. a1 CAPABILITY * CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE STARTTLS AUTH=PLAIN a1 OK Capability completed. However after a user has logged in, Dovecot 2.0.rc3 returns all supported capabilities: * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE STARTTLS AUTH=PLAIN] Dovecot ready. a1 login user(a)example.com pass a1 OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT IDLE CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS QUOTA ACL RIGHTS=texk] Logged in a2 CAPABILITY * CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT IDLE CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS QUOTA ACL RIGHTS=texk a2 OK Capability completed So what's the idea behind the change of this behavior? Is it planned to support different capabilities per user in the future? The reason behind my question is, that the Open-Xchange IMAP client implementation relies on the presence of the ACL capability presented before the actual login took place. Thanks for any clarifications. Regards Christian

[Dovecot] OT dovecot w/postfix, mysql , postfix does unnecessary lookups
by Noel Butler 04 Aug '10

04 Aug '10

I know this unnecessary lookups question is really a postfix one, but I'm curious if anyone else sees the behaviour of postfix continuing looking up users after it clearly have got its answer that it is "not a local domain" response. (this msg is an extract from what I sent to WV some time ago, with him showing absolutely no interest, I got bored tonight so thought I'd throw it on this list since the question remains valid today) 30 Query SELECT 1 FROM virtual_domains WHERE name='example.net' AND active ='1' 31 Query SELECT destination FROM view_aliases WHERE email='someuser(a)example.net' Should that not have ended its lookups at Q30 and not gone on to ask Q31 which it now knows is not local? Secondly, it seems to do "double lookups" of destination and email before it gets to dovecots deliver, has anyone else ran a log on mysql and seen same? I'm trying to work out why, since it already has its answer by Q54 and Q55, it is doing Q56 and Q57, which seem pointless... 54 Connect 54 Query SELECT destination FROM view_aliases WHERE email='laura(a)example.com' 55 Connect 55 Query SELECT email FROM view_users WHERE email='laura(a)example.com' 56 Connect 56 Query SELECT destination FROM view_aliases WHERE email='laura(a)example.com' 57 Connect 57 Query SELECT email FROM view_users WHERE email='laura(a)example.com' So, it to me appears postifx does more work then it needs too since it already knows the answer, I consider this a flaw in postfix, yet perhaps I am the only one seeing it hence why WV couldnt give a shit. just curious if anyone has noted same or not....
