[Dovecot] Some POP3 questions
by Kenneth Kalmer 06 May '09

06 May '09

Hi everyone Been spending the whole day on the wiki and in the list archives on using dovecot for POP3 mail. I'd like to present my findings and ask for some feedback. Our current software setup: * Courier-IMAP running POP3/IMAP * Postfix MTA * MySQL backend for user and login info As for the system layout, it looks like this: * NFS server which is the same server that houses single Courier-IMAP installation (Gentoo, 3GB memory) * 2x Postfix instances delivering to NFS * Mail directory structure: /mail/e/ex/example.com/user Usage: * Currently reaching in excess of 1,200 concurrent connections, traffic roughly 36GB per day * 90% POP3 (mostly pop+delete), 10% IMAP * ~170GB of mail on disk Current problems experienced: * Massive load averages (>500) * Memory exhaustion (3GB) * Server looses network connectivity (related to massive loads) I've got a new server ready for action, well after mail directories have been rsync'd over. Will have 8GB of memory and much fast discs. I'm looking at giving Dovecot + Postfix/LDA a go. From my research today it seems that running a POP server without LDA (or without the W=(\d+) filename field) is a futile business. I'm running Gentoo, and the stable release in portage is currently dovecot 1.1.7, with 1.1.14 being available but masked. Long stories short, will Dovecot with the Postfix/LDA give performance equal than Courier-IMAP or improved (because of the cached message sizes)?

Yes. Now i have two new issue: 1. "Content-Type:" header in mail wrong - so it's TEXT/mspowerpoint for example, but it's binary *.ppt file. 2. many html from repository change-set(many commit's to html) in text/plain mail In both cases we have "Error 500" from solr (HTMLStripReader class) (in solr log: "Marked inlalid"). And in both cases we can not detect this in dovecot code (or it's hard to do). So for now i need some method to ignore "bad" messages. Because we can not catch all variants, but indexing die on first error like this. Powered by the 6zap.

[Dovecot] NTLM configuration
by Cédric Laruelle 06 May '09

06 May '09

Hi all, Im actually running samba 3 as a primary domain controller. The workstations of my network are all running windows (some xp, some vista) and use Outlook 2007 as a web client. Samba is set up with the following parameters : security = user passdb backend = tdbsam unix password sync = Yes domain master = yes domain logons = yes Everything works fine on samba side, meaning that the machines are part of the domain, and users do authenticate correctly. For the moment, the users are getting their mail (pop3 or imap) through dovecot (running on the same box as samba). Dovecot is configured with mechanisms = plain. I would like to secure it by using mechanisms = ntlm, but still using the system users. I found much information on how to authenticate against an active directory, but nothing that allows me to keep my actual authentication against system users. Indeed, if I just change the mechanisms to ntlm, dovecot does not start anymore complaining that NTLM mechanism can't be supported with given passdbs Any help would be much appreciated as I already tried the whole day yesterday to get it working Best regards, Cédric Laruelle

[Dovecot] Testing POP3 with telnet - password always wrong
by Timothy Legg 06 May '09

06 May '09

Hello, I just installed the postfix and dovecot packages according to the document, http://www.debianadmin.com/debian-mail-server-setup-with-postfix-dovecot-sa… And it has been quite helpful. It looks like Dovecot works because I can communicate with it on port 110. I can't help but feel I am doing something stupid though... The web page listed above told me to test the POP3 server using Outlook Express, and well, I am just not going to do that. Not when I can do it by hand... legg@debian:~$ telnet 192.168.10.171 110 Trying 192.168.10.171... Connected to 192.168.10.171. Escape character is '^]'. +OK Dovecot ready. USER test(a)192.168.10.171 +OK PASS password1 -ERR Authentication failed. But why do I always get the password wrong? I twice set the password for the test user and also restarted Dovecot, but the password is always wrong. Note that disable_plaintext_auth=no. I'm sure there must be something stupid I have overlooked. Any suggestions? Thank you very much!!!! Tim Legg Here is some additional data that I am volunteering... # dovecot -n # 1.0.15: /etc/dovecot/dovecot.conf 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_privileged_group: mail 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 pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv auth default: passdb: driver: pam userdb: driver: passwd # dovecot --version 1.0.15

[Dovecot] Unable To Send Mail
by Carlos Williams 05 May '09

05 May '09

I just installed CentOS 5 + Postfix + Dovecot. Now When I send mail via telnet from one user to another via Postfix (MTA), I have no problem. The recipient gets the message perfectly. Now this tells me that Postfix is working fine (I assume) but then I configured Dovecot to use IMAP4 and then configured my Thunderbird client. Now all the messages I previously sent using Telnet showed up in Thunderbird Inbox but then when I attempt to send a message via Thunderbird, the message appears to send fine however the recipient never gets it and I get no delivery failrures back of any kind. I check the Postfix (MTA) mail queue and it shows empty. What is causing this anyone? Does anyone know why this is not working? Here is my postconf -n for Postfix (MTA) [root@nat home]# postconf -n alias_database = hash:/etc/aliases alias_maps = hash:/etc/aliases command_directory = /usr/sbin config_directory = /etc/postfix daemon_directory = /usr/libexec/postfix debug_peer_level = 2 home_mailbox = mail/ html_directory = no inet_interfaces = all mail_owner = postfix mailq_path = /usr/bin/mailq.postfix manpage_directory = /usr/share/man mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain mydomain = wtf.com myhostname = nat.wtf.com myorigin = $mydomain newaliases_path = /usr/bin/newaliases.postfix queue_directory = /var/spool/postfix readme_directory = /usr/share/doc/postfix-2.3.3/README_FILES sample_directory = /usr/share/doc/postfix-2.3.3/samples sendmail_path = /usr/sbin/sendmail.postfix setgid_group = postdrop smtpd_banner = $myhostname ESMTP $mail_name unknown_local_recipient_reject_code = 550 ================================================================ Here is what is 'UNCOMMENTED' in my /etc/dovecot.conf protocols = imap imaps mail_location = maildir:~/mail protocol imap { imap_client_workarounds = delay-newmail outlook-idle netscape-eoh } login_process_size = 64 protocol pop3 { protocol lda { protocol lda { postmaster_address = carlos(a)wtf.com } auth default { mechanisms = plain passdb pam { } userdb passwd { } user = root } dict { } plugin { } Anyone know what is causing this problem above? Sending internal email works fine via Telnet however when I try using my mail client / imap4, nothing happens.

[Dovecot] Disabling users whilst still allowing logins with a 'master password'
by Dominic Hargreaves 05 May '09

05 May '09

Hi, I'm having trouble coming up with an authentication configuration that does what we want with dovecot, and thought it would be worth passing it by the list in case anyone can spot an easy fix, or confirm my suspicions that code changes are required. You should probably be aware that this is to support a migration away from Dovecot to a certain Microsoft-provided mail platform, so if this makes you feel uncomfortable, you may choose not to respond ;) We have the following configuration: - the passdb in use is pam (for pam_krb5) - the userdb in use is passwd (for nss_ldap) - GSSAPI is also supported - We support both IMAP and POP - Dovecot 1.0.9 - users have their own uid/gid and the following requirement, in order to support the migration process: - Access to mailstore should be allowed by means of a master password or user (ideally configurable, so we have a fine degree of control over which users are exposed to the migration process at a given time) - Migration process accesses mailstore via IMAP - During migration, users should not be allowed to log in with their Kerberos password, nor with GSSAPI We've achieved the first requirement with master passwords roughly as described at the bottom of http://wiki.dovecot.org/Authentication/MasterUsers by configuring another passdb with the master password hash in place for the users we want to be enabled to migrate. Our standard auth config looks like: auth default { gssapi_hostname = imap210.herald.ox.ac.uk mechanisms = plain login gssapi passdb pam { } userdb passwd { args = blocking=yes } socket listen { master { path = /var/run/dovecot/auth-master } } } and my first try at satisfying my requirements was: auth default { gssapi_hostname = imap-dev.herald.ox.ac.uk mechanisms = plain login gssapi passdb sql { args = /etc/dovecot/dovecot-sql-master.conf } passdb sql { args = /etc/dovecot/dovecot-sql-deny.conf deny = yes } passdb pam { } userdb passwd { args = blocking=yes } socket listen { master { path = /var/run/dovecot/auth-master } } } where /etc/dovecot/dovecot-sql-master.conf describes a query representing those users accessible by the master password (and a hash of the master password) and /etc/dovecot/dovecot-deny.conf describes a query representing those users who should not be allowed to log in with their normal password (or GSSAPI). This almost works, but unfortunately (as documented) the GSSAPI mechanism does not check any passdbs, so does not get checked against the deny passdb. Normally to disable logins for a user we chmod their mail store to 0 so they can't access it, which has the same effect, but this obviously also prevents the master password from being able to access it. It would seem to be generally useful to be able to check GSSAPI logins against a deny passdb, but is this a valid code change? Alternatively, could the *userdbs* could be extended to cope with the idea of a deny form, since the GSSAPI login process already uses them (although it would have to return USERDB_RESULT_USER_UNKNOWN). Alternatively, does anyone have any other ideas about how I could achieve the same effect? Thanks for listening.

[Dovecot] Maildir bugs
by Timo Sirainen 05 May '09

05 May '09

I just found out that when using deliver or saving mails with IMAP APPEND command there was all kinds of race condition bugs that could cause e.g.: dovecot-uidlist: Duplicate file entry at line 18: 1241457213.M690227P32531.host,W=3359:2,T (uid 170019 -> 170020) And who knows what else. If you've run into those problems, these patches should help: http://hg.dovecot.org/dovecot-1.1/rev/6bbe27c32cb8 http://hg.dovecot.org/dovecot-1.1/rev/003bebac2c76 http://hg.dovecot.org/dovecot-1.1/rev/96c8632775df They are pretty large though, hopefully won't break anything. But at least my stress tests can no longer break it. I'll probably release v1.1.15 RC in a few days so at least some people can try to break it before the final v1.1.15 :)

[Dovecot] questions about compiling Sieve plugin
by MercuryShadow 04 May '09

04 May '09

I'm using the info on the wiki to try to compile the sieve plugin for dovecot on a server running Debian Etch, but I'm getting nowhere because I'm stuck trying to find the directory to use in the "--with-dovecot=" argument when running the configure script. The wiki says: Compilation is identical among the CMUSieve and the new Sieve plugin. Use --with-dovecot=<path> to point to dovecot-config file's directory. There are two possibilities where this could exist: 1. If you configured Dovecot with --enable-header-install, you'll have dovecot-config installed in $prefix/lib/dovecot/ directory. 2. Compiled Dovecot sources' root directory. The problem is that there is no such file called "dovecot-config" on the server, and dovecot was installed from the Debian repositories, not compiled. There is no /usr/lib/dovecot or /usr/local/lib/dovecot. I figured that, as is the case with many Debian packages, the libraries needed to compile would be included in a "dovecot-dev" package, but I checked and there is no such package in the Debian repos. Does anyone know what I need to do in order to get this plugin compiled? -- View this message in context: http://www.nabble.com/questions-about-compiling-Sieve-plugin-tp23285989p232… Sent from the Dovecot mailing list archive at Nabble.com.

Hi, I've changed a program that fetches mail via IMAP from an Exchange Server to use our Dovecot machine. But now I'm experiencing strange problems with seem to be caused by a wrong BODYSTRUCTURE answer that causes wrong charset handling. When fetchting the BODYSTRUCTURE I see this: Dovecot: 88 UID fetch 32 (BODYSTRUCTURE) * 1 FETCH (UID 32 BODYSTRUCTURE ("text" "plain" ("charset" "us-ascii") NIL NIL "7bit" 725664 9385 NIL NIL NIL NIL)) 88 OK Fetch completed. Exchange: 90 UID fetch 10 (BODYSTRUCTURE) * 2 FETCH (BODYSTRUCTURE (("TEXT" "PLAIN" ("charset" "iso-8859-1") NIL NIL "QUOTED-PRINTABLE" 2784 47 NIL NIL NIL)("IMAGE" "JPEG" ("name" "197254.jpg") NIL NIL "BASE64" 498806 NIL ("attachment" ("filename" "197254.jpg")) NIL)("IMAGE" "JPEG" ("name" "197254_1.jpg") NIL NIL "BASE64" 188424 NIL ("attachment" ("filename" "197254_1.jpg")) NIL)("IMAGE" "JPEG" ("name" "197254_2.jpg") NIL NIL "BASE64" 31878 NIL ("attachment" ("filename" "197254_2.jpg")) NIL)("TEXT" "PLAIN" ("name" "pix.xml") NIL NIL "QUOTED-PRINTABLE" 2934 49 NIL ("attachment" ("filename" "pix.xml")) NIL)("TEXT" "PLAIN" ("CHARSET" "US-ASCII") NIL NIL "7BIT" 0 1 NIL ("attachment" NIL) NIL) "mixed" ("Message-ID:" "<d2788bc14788ff16e67e63941937c1e1(a)foo.de>" "boundary" "000XMAIL000") NIL NIL) UID 10) 90 OK FETCH completed.

Any hint would be appreciated... Thanks in advance, Craig

OK. Concentrating problem in one question. How to ignore "bad" message and index next one in indexing procedure (fts plugin) ?.

[Dovecot] login_max_processes_count and logs
by Dominique Fournier 04 May '09

04 May '09

Hello, Our server reach today the login_max_processes_count. Dovecot works well and don't accept any new connection. But it doesn't log anything about this problem : we are blind why the connection is refused for the clients. Could you add a log when the connection limit is reached or (maybe better) a log with the occupation for the beginning of each connection ? Thanks Dom Dovecot version 1.0.15 on Debian AMD64

[Dovecot] Strange virtual users issues
by Ovi C 02 May '09

Hi i'm using dovecot with virtual users from a postgresql database backend on a Debian Lenny system. I'm using qmail as MTA. Mostly everything seems to work ok , except the fact that the mail delivered never reaches virtual user's INBOX. Here's the dovecot config: dovecot -n # 1.0.15: /etc/dovecot/dovecot.conf base_dir: /var/run/dovecot/ log_path: /var/log/dovecot.log log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap ssl_disable: yes login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login login_greeting: Server ready to process requests. login_process_per_connection: no max_mail_processes: 512 verbose_proctitle: yes first_valid_gid: 61 last_valid_gid: 2003 mail_privileged_group: mail mail_location: maildir:~/Maildir mail_debug: yes mail_plugins: quota autocreate imap_client_workarounds: outlook-idle delay-newmail auth default: mechanisms: plain login digest-md5 passdb: driver: pam passdb: driver: passwd passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: passwd userdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: prefetch socket: type: listen client: path: /var/run/dovecot/auth-client mode: 432 master: path: /var/run/dovecot/auth-master mode: 384 user: root group: mail plugin: quota: maildir acl: vfile:/etc/dovecot-acls trash: /etc/dovecot-trash.conf lazy_expunge: .EXPUNGED/ .DELETED/ .DELETED/.EXPUNGED/ autocreate: Trash autocreate2: Spam The setup is as follows: I've created a system user named vmail in /home with a group also called vmail. The virtual users are created in /home/vmail/username when i configure an account from thunderbird. If I send an message from a virtual user to an system user everythings is ok. The system user get's the mail in his Maildir. But if I send a message from the system user to the virtual user the MTA's log says that the message has been delivered but it never reaches virtual user's INBOX. Here's a snip from logs both qmail's and dovecot's: cat /var/log/qmail.log status: local 0/10 remote 0/20 new msg 155041 info msg 155041: bytes 263 from <caretaker@localhost.> qp 4560 uid 1000 starting delivery 1: msg 155041 to remote akkersson@localhost. status: local 0/10 remote 1/20 new msg 155147 info msg 155147: bytes 438 from <caretaker@localhost.> qp 4563 uid 64011 starting delivery 2: msg 155147 to local akkersson@localhost status: local 1/10 remote 1/20 delivery 1: success: 127.0.0.1_accepted_message./Remote_host_said:_250_ok_1241272738_qp_4563/ status: local 1/10 remote 0/20 end msg 155041 delivery 2: deferral: status: local 0/10 remote 0/20 cat /var/log/dovecot.log dovecot: 2009-05-02 16:30:46 Info: Dovecot v1.0.15 starting up dovecot: 2009-05-02 16:30:46 Info: auth(default): pgsql: Connected to maildb dovecot: 2009-05-02 16:32:00 Info: IMAP(akkersson): Loading modules from directory: /usr/lib/dovecot/modules/imap dovecot: 2009-05-02 16:32:00 Info: IMAP(akkersson): Module loaded: /usr/lib/dovecot/modules/imap/lib10_quota_plugin.so dovecot: 2009-05-02 16:32:00 Info: IMAP(akkersson): Module loaded: /usr/lib/dovecot/modules/imap/lib11_autocreate_plugin.so dovecot: 2009-05-02 16:32:00 Info: IMAP(akkersson): Effective uid=2003, gid=61, home=/home/vmail/akkersson dovecot: 2009-05-02 16:32:00 Info: IMAP(akkersson): maildir: data=/home/vmail/akkersson/Maildir dovecot: 2009-05-02 16:32:00 Info: IMAP(akkersson): maildir: root=/home/vmail/akkersson/Maildir, index=/home/vmail/akkersson/Maildir, control=, inbox= dovecot: 2009-05-02 16:32:00 Info: imap-login: Login: user=<akkersson>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured dovecot: 2009-05-02 16:58:11 Info: IMAP(akkersson): Disconnected: Logged out but akkersson's INBOX is empty..

Great. Thank you so much for responding. It hangs at Tying 127.0.0.1 The funny part is that one day it works fine and the next day it just hangs. And its not that the service is completely unresponsive. If 200 users try to connect, 10 get through and are able to download. However which 10 get through depends on luck!

[Dovecot] fts-solr plugin issue (Marked invalid)

Hi. We user ftp-solr plugin and have problem with solr-1.3+ with HTMLStripWhitespaceTokenizerFactory (Solr schema in attachments). In some maildir's present messages with wrong "Content-Type: " fields in attachments. For example: " Content-Type: TEXT/mspowerpoint; name="Zapatec_6zap_netvibes_1.ppt" " Indexing for this messages is stop with "fts_solr: Indexing failed: 500 Internal Server Error". In solr log is: " SEVERE: java.io.IOException: Mark invalid at java.io.BufferedReader.reset(BufferedReader.java:485) " (mail list with discussion: http://markmail.org/message/2fnfiwygvehjngyr#query:SEVERE%3A%20java.io.IOEx…) Look's like dovecot try to index attachments like this. Also for some messages we have same error. Dovecot stop indexing of box and each search we have lag and CPU load on server. So we need to make dovecot more "stable" to this error. For first time , will be good, just ignore problematic messages with error from solr. Let's discuss this issue, because this is general problem. We ready to explore code where needed , etc. Regards, Nikolai Powered by the 6zap. Sign up at http://www.6zap.com for an account that provides advanced e-mail, calendar and contacts capabilities.

[Dovecot] Installed include files
by Timo Sirainen 01 May '09

01 May '09

Currently when using configure --enable-header-install and doing make install the include files get installed to their own subdirectories, like: /usr/local/include/dovecot/src/lib/ /usr/local/include/dovecot/src/lib-mail/ ..etc.. But using that is kind of annoying, because you have to give -I paths to all of them with their full directories. The worst thing about that is that it requires having some kind of a --with-dovecot=path configure parameter. It would be nice if you could simply do: CPPFLAGS=-I/usr/local/include/dovecot ./configure Just like for any other include option. But that's not really possible. One possible way to fix it would be to just install all the .h files to a single directory, /usr/local/include/dovecot/ and make sure there aren't any conflicts (there currently are a few). But whis would make it more difficult to find out what files are related. Another possibility would be to put the subdir paths to all #include lines. Such as #include "lib-mail/mail-types.h" instead of just #include "mail-types.h". This seems kind of annoying to use, but would it be clearer? I'm not really sure. Anyone have any thoughts?

[Dovecot] Case sensitive oddity when mail delivered.
by dovecot＠corwyn.net 01 May '09

01 May '09

Currently running Postfix/Dovecot1.1.8 with mysql storing the user data and delivering to folders as determined by dovecot using dovecot's "deliver" as defined in postfix's master.cf Mail location is determined by mail_location = maildir:/var/spool/mail/%d/%n/Maildir If I have an account user1(a)example.com it works just fine. However, when mail is sent to USER1(a)EXAMPLE.COM it also delivers, but ends up creating a new file structure so I end up with /var/spool/mail/example.com/user1 (with lower case mail in it) and /var/spool/mail/EXAMPLE.COM/USER1 (with uppercase mail in it) which is decidedly not good. Looks to me like wherever %d and %n are pulled from is pulled out of the email, but not lower-cased. Any ideas where I would look to change this value before the email is delivered to the mailbox?

[Dovecot] How to call a script when an E-Mail will moved in a folder?
by Luca Bertoncello 30 Apr '09

30 Apr '09

Hi, list! I use Dovecot 1.1.14 at work. It is configured to manage IMAP and IMAPs. Exim is the MTA of the Network. Of course, I installed SpamAssassin and ClamAV to check all incoming E-Mails. An, of course, some E-Mail marked as Spam are Ham and some E-Mail marked as Ham are Spam... To teach SpamAssassin I create for every user two folder: "DochSpam" (for Spam E-Mails not marked) and "FalscheSpam" (for Ham E-Mails marked as Spam). Every hour a cronjob search for E-Mails in these folders and call sa-learn to teach SpamAssassin. All run perfectly, but I'd like to modify this method and call automatically the script when the user move an E-Mail to DochSpam or FalscheSpam. I searched in Google, but I cannot found any useful link... How can I trigger an action (script calling) based on event (E-Mail will be moved to a folder) in Dovecot? Thanks for your help!

Re: [Dovecot] Unexplainable problem with POP3 quotas

> No, we don't. We use dovecot as POP/IMAP server, and let Postfix do the rest.

I just tested the quota-warning, with the dovecot-deliver-example. Exactly the same time as the mail exceeding the quota-percentage is delievered in the account, the quota-warning-message is generated and also delivered. > Anyway, we are neither sending an email nor using deliver. What we are > trying to do is to generate a message file that is injected into the > mailbox. But the script that should do that is never run by dovecot > :-( Try the injection using deliver, and use the "alternative script" from the wiki-page as quota_warning. I just tested it, works great. Also: when using dovecot-deliver, the maildir-indizes are being generated better and faster than with alternative MDAs. Best regards, Anton

[Dovecot] Unexplainable problem with POP3 quotas
by Marco Marongiu 30 Apr '09

30 Apr '09

Greetings * We are having a problem with POP3 quota warnings, and despite we dig into the documentation, mailing list archives, google... we didn't spot any light We are running a self-compiled dovecot 1.1.7. The user base is in a Postgres database. We'd like a quota warning message to be injected into the maildir at 80% and 95% of occupation reached. >From the logs, it looks like dovecot is correctly reading the quotas from the DB. Nevertheless, the warning message is never delivered. We tried many different configurations (e.g.: from using bytes instead of storage to change the quota configuration alltogether, I think we tried every single sensible, applicable solution that we could spot during our searches in the net). Currently, we have the following non-working one: root@mgo2-popimap-v01:/usr/local/dovecot/etc# ../sbin/dovecot -n # 1.1.7: /usr/local/dovecot_1.1.7/etc/dovecot.conf Warning: fd limit 1024 is lower than what Dovecot can use under full load (more than 16384).

[Dovecot] Quota: ldap dict
by Marcio Merlone 29 Apr '09

29 Apr '09

Hi, I have set a dovecot-1:1.0.10-1ubuntu5.1 server on top of a Ubuntu 8.04 LTS box and everything goes fine. All my users are on a LDAP database integrated via nss_ldap, so from the dovecot point of view they are all local system users. Now I want to set maildir quota for everybody, and was wondering if I could store quota limits per user on LDAP. As I read on http://wiki.dovecot.org/Quota/Dict, there seem to be no way to do that, am I right? It is ok for me to manage the current usage on Maildir++, but would like to retrieve the quota information from the LDAP server. What do you guys recommend? Thanks in advance for any hint or rtfm. Best regards. -- Marcio Merlone

[Dovecot] Dovecot v2.0 hg tree
by Timo Sirainen 29 Apr '09

29 Apr '09

http://hg.dovecot.org/dovecot-2.0/ I just did the initial commit for master process rewrite, which marks the beginning of Dovecot v2.0. Several things are still missing/broken, but at least I was just able to successfully log in using imap :) I left v1.3 hg tree there for now, but once v2.0 tree is fully usable I'll just delete the v1.3 tree. Note the new dovecot-master-example.conf, which you'll need to !include to get the services running. Some settings have also been removed because they're now more generically set in the dovecot-master.conf. I'm thinking that perhaps the config process could still be run in compatibility mode where it's able to use an existing v1.x dovecot.conf and translate the old settings to new settings.

[Dovecot] Slow connections with POP3 service
by V S Rao 29 Apr '09

29 Apr '09

Hi All, I am facing a very strange issue with the pop3 server for the past one week. I run my mail service using sendmail & use UW-IMAP for POP3 & IMAP service. We have around 5000 users. Suddenly for the past one week I am facing very slow connections for POP3 alone on that server. Other services such as SMTP, IMAP, telnet, ssh etc work fine. Assuming that UW-IMAP may have an issue, I download the latest dovecot, compiled it and installed it. This also gives the same issue. I do not any firewall issues nor iptables is enabled. I have checked on the network to ensure that I do not have any kind of virus or DoS attacks using an IDS. I am unable to see any 'Strange' messages in /var/log/messages or maillog. What is strange is that it works one day without any issues and the next day the problem persists. Even a telnet to localhost on port 110 is very very slow. Can someone help with any ideas on how to troubleshoot? This is our production box. Thanks V S Rao

[Dovecot] Quota/Dict Postgres Trigger
by Warren Volz 29 Apr '09

29 Apr '09

I posted the trigger for v1.1 versions of Dovecot on the Wiki (http://wiki.dovecot.org/Quota/Dict ) and while I understand the comment posted about two process inserting at the same time, I'm not sure I understand how this is fixed in v1.2 other than via the revised trigger in the Wiki. Does someone have a known working trigger that will handle a double insert correctly? Also, out of curiosity why wasn't the code for dict written to do an update first and then an insert if this failed? That would eliminate the need for this trigger. Thanks. -Warren

[Dovecot] Mail statistics
by Timo Sirainen 29 Apr '09

29 Apr '09

I just committed a mail statistics gathering patch to v1.2: http://hg.dovecot.org/dovecot-1.2/rev/fdaf0bda70d5 It keeps track of: struct mail_private { .. /* open(), stat(), .. */ unsigned long stats_dentry_lookup_count; /* fstat() mostly */ unsigned long stats_attr_lookup_count; /* number of files we've opened and read */ unsigned long stats_files_read_count; /* number of bytes we've had to read from files */ unsigned long long stats_files_read_bytes; /* number of cache lookup hits */ unsigned long stats_cache_hit_count; So it's possible to write a plugin that does whatever with those values. You can get them per-command or even per-single-mail-access. Any thoughts on if those are good variables? Like would it be useful to split dentry lookups to opens and stats?

[Dovecot] Virtual mailbox plugin, 4 days of struggling
