[Dovecot] user_attrs seems not to set 'mail'.
by ian＠comtek.co.uk 12 May '09

12 May '09

Hi, I am using Dovecot 1.1.13 (from a Debian package). I was having problems using user_attrs to set 'mail' and 'home'. Initially I tried: user_attrs = uid=mail=maildir:/var/mail/virtual/users/%$/Maildir/,uid=home=/var/mail/virtual/users/%$/ This appeared to set 'home' but not 'mail'. In the debug lot I see: May 12 15:24:40 alpha dovecot: auth(default): ldap(X(a)Y,10.4.4.113): user search: base=ou=users,dc=Y scope=subtree filter=(& (mail=X@Y) (|(accountStatus=active) (accountStatus=migrate)) ) fields=uid,uid May 12 15:24:40 alpha dovecot: auth(default): ldap(X(a)Y,1.1.1.1): result: uid(home=/var/mail/virtual/users/%$/)=/var/mail/virtual/users/uid/ May 12 15:24:40 alpha dovecot: auth(default): master out: USER 30688 X@Y home=/var/mail/virtual/users/uid/ Note that 'home' seems to be set on the last line, but not 'mail'. I was hoping to see 'mail=/var/mail/virtual/users/uid/Maildir/'. Next I tried: user_attrs = =mail=maildir:~/Maildir/,uid=home=/var/mail/virtual/users/%$/ Now I see: May 12 15:31:28 alpha dovecot: auth(default): ldap(X(a)Y,1.1.1.1): user search: base=ou=users,dc=Y scope=subtree filter=(& (mail=X@Y) (|(accountStatus=active) (accountStatus=migrate)) ) fields=uid May 12 15:31:28 alpha dovecot: auth(default): ldap(X(a)Y,1.1.1.1): result: uid(home=/var/mail/virtual/users/%$/)=/var/mail/virtual/users/uid/ May 12 15:31:28 alpha dovecot: auth(default): master out: USER 30712 X@Y home=/var/mail/virtual/users/uid/ mail=maildir:~/Maildir/ Now both 'home' and 'mail' are set, which is what I want. This means the following lines are not synonymous: user_attrs = uid=mail=maildir:/var/mail/virtual/users/%$/Maildir/,uid=home=/var/mail/virtual/users/%$/ user_attrs = =mail=maildir:~/Maildir/,uid=home=/var/mail/virtual/users/%$/ Either I misunderstand the documentation for user_attrs or there is a bug. Assuming the former, can somebody please explain what I am doing wrong? Thanks, Ian

[Dovecot] Dovecot auth user lookup patch updated for maildrop 2.1.0
by mr.maX 12 May '09

12 May '09

Hi, an updated version of my patch for maildrop that extends it with the ability to perform user lookups against Dovecot's database made against the latest version of maildrop 2.1.0 can be downloaded from the following location: http://www.max.rs/ozone/maildrop-2.1.0-dovecotauth.patch.txt The patch has just been redone in order to apply cleanly without fuzz and to apply properly against one file that was changed in the latest version of maildrop. There have been no other changes compared to the initial version of the patch. For more information, take a look at my previous post to the Dovecot's mailing list at: http://www.dovecot.org/list/dovecot/2009-April/039121.html -- Best Regards, Marko Njezic - mr.maX @ MAX Interactive corp.

[Dovecot] Fail2Ban and the Dovecot log
by Lou Duchez 12 May '09

12 May '09

Hi, Is there any way to disable the "dovecot: " at the beginning of each line of the log? Fail2Ban responds poorly to it. I know there are a number of sites with "failregex" strings for Fail2Ban and Dovecot, but I've tried them all, and they don't work, at least with the latest Fail2ban and the latest Dovecot. The Fail2Ban wiki is pretty clear about why there will be a problem: "In order for a log line to match your failregex, it actually has to match in two parts: the beginning of the line has to match a timestamp pattern or regex, and the remainder of the line has to match your failregex.". So in other words, Fail2Ban expects that each line of the log will start with a timestamp. Thanks all! Dovecot rocks.

[Dovecot] Sieve & Regex
by Peregrino "Pipino" Tuc 12 May '09

12 May '09

Hi all I'm trying to create a new sieve rule. What I would like to do is catch "From" addresses that are equal to the rightpart (hostname) of a message-id. For example: Message-ID: <000d01c9d23a$941a7db0$6400a8c0@upwabm> From: "Leanne Crabtree" <upwabm(a)blomberg-co.com> I would like to catch this mail, because it has "upwabm" on the right part of the message-id and "upwabm" on the left part of the sender address. I've done this, but with no success. The error reported is: "Invalid preceding regular expression" on line with the second regex with ${1} More over I would like to add an header with the result of regex, an header like this: "X-MyHeader" "${1}" but it does not work. This is an extract of our sieve: --- require ["regex"]; if header :regex "Message-ID" "^.*(a)(.*)>$" { if header :regex "From" ".*<${1}@.*>$" { addheader "X-MyHeader" "${1}" } } ---

[Dovecot] Quota over NFS
by Flavio Costa 11 May '09

11 May '09

Hey, I've been strugling to get quota working on my enviroment. I have one storage server that exports the 'home' dir. My mail server mounts the exported 'home' server at '/home' # dovecot --version > 1.1.14 I'm also running Postfix and using Dovecot/LDA as MDA so that we can use the Dovecot's Quota plugin. The thing is that if the user has exceeded it's quota the LDA detects it and I get a response from postmaster warning me that the INBOX is full. But through IMAP, if I issue : > C: 1 GETQUOTAROOT INBOX > S: * QUOTAROOT INBOX "" > S: 1 OK Getquota complete > > There's no: > * QUOTA "" (STORAGE 10 512) > > I've tried using this plugin for Thunderbird: https://addons.mozilla.org/pt-BR/thunderbird/addon/881 And also tested issuing commands by hand. Running 'quota' on the console works just fine, that means that rpc.rquotad is running smoothly. # quota USER > Disk quotas for user coutinho (uid 1191): > Filesystem blocks quota limit grace files quota limit > grace > home.mail:/home > 166264* 102400 153600 3013 0 > 0 > Thanks in advance for you help. -- Flávio Coutinho da Costa

[Dovecot] dovecot weird bug
by Fernando Bertasso 11 May '09

11 May '09

Hi, We have a weird bug happening in our dovecot installation. When I send html emails from many clients and compress them, there are no problem. They are opened and correctly formated. When I send an email from Squirrelmail and compress it, dovecot exits with no errors (there are no coredumps or seg fault - dovecot just exits). But the weird is, it just happens when squirrelmail opens an email (compressed) that was sent by squirrelmail (all other clients can open it and squirrel can open all other emails sent by other clients). (Try with this message - compressing too - it occurs with me).

[Dovecot] dovecot weird bug
by Fernando Bertasso 11 May '09

11 May '09

I found the bug, there are two errors: 1) Squirrelmail is wrongly formating multipart/alternative messages. Look here: ------=_20090510163738_24160 Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: 8bit a<br /> *<------ HERE* ------=_20090510163738_24160-- All other clients insert an '\n' here, but squirrelmail. 2) When this king of message (above) is compressed (in order to use zlib plugin), dovecot dies.

[Dovecot] Dovecot not accepting connections
by Jim 11 May '09

11 May '09

Hi, new user here, trying to track down an issue. Sometimes, after starting dovecot, I'll attempt to check mail and will not be able to get a connection to my server. I'll kill dovecot, restart it, and usually it will begin working. When I first ran into this, I first tried auth_debug=yes, restarted dovecot, and had no problems. I'd turn set auth_debug=no, restart dovecot, and would be unable to check mail. After a time I determined that setting the debug wasn't really effecting anything, it was just hit or miss if I'd be able to get a connection. Once I was able to get a connection, things were fine until dovecot started again. Nothing unusual in the logs, if it works or not, I'll just see this at startup: Mar 25 21:34:48 mail-web-server dovecot[664]: dovecot v1.1.13 starting up (core dumps disabled) Mar 25 21:34:48 mail-web-server dovecot[664]: auth-worker(default): mysql: Connected to localhost (postfix) If debug is on and connections aren't being accepted, I never see anything in the logs.

[Dovecot] Degeneration of CPU Performance
by Thiago Monaco Papageorgiou 11 May '09

11 May '09

Hello everybody! We have a interesting issue about dovecot behavior here. First, the scenario: We have 2 server running with the same load, one with our old pop3 solution (out of date) and other with Dovecot. We realized that dovecot are comsuming more CPU, and this consumption is growing day by day. When we starts dovecot, it runs between 40%-45% of CPU consumption and our old solution runs on 30-35%. This is quite acceptable, so no problem here. The problem is one day after it jumps to 45%-55% of cpu comsunption while the old pop3 solution runs on the same CPU consumption of one day before (30%-35). I attached a graph with this information. In this graph the green line is dovecot CPU consumption and the blue line is the old solution. In this graph we restart dovecot at monday morning. This restart is noticed as a big fall of CPU consumption(green line) in the graph. After that, it stay between 40%-45%, one day after it runs on 45%-55% and next day, it reaches 50%-60%! You can notice that the blue line (old pop3 solution) runs with the same behavior, so we have the same load. We have other monitoring informations that confirm it. I looked for some bugs about this, but I didn't find anything. The question is: Is there any dovecot problem or wrong configuration that could cause this degeneration of CPU performance? Any sugestion about what can be the cause of this? I attached dovecot -n output. Two important information: we store the mailboxes in NFS and we are only using pop3 protocol.

[Dovecot] Unit testing
by Timo Sirainen 09 May '09

09 May '09

Unit testing is slowly going forward in Dovecot. In v2.0 tree all the unit tests are now run when you do "make check". They're also run on "make distcheck", which is what I use when building releases or nightly snapshots. So as soon as I start building nightly v2.0 snapshots I should start getting mails every night if the unit tests fail. And I can no longer make a release if a unit test fails. (Unit tests never get run manually - I once fixed a unit test that had been failing for months.) Besides that, I started trying to add unit tests to lib-index. After some hours of refactoring the code I finally managed to get mail-transaction-log-view and mail-index-transaction to a condition where unit tests could be added to them without too much pain. I didn't really add that many unit tests there yet though. I'll probably slowly continue adding more tests and refactoring the code more to allow more unit tests, but if anyone else finds they have nothing better to do, now's a good time to add more tests :) Especially lib/, lib-mail/ and lib-imap/ should already be easily testable and they're missing a lot of tests.

[Dovecot] dovecot slowing down
by P.A 08 May '09

08 May '09

Hi, not really a dovecot issue but, im running dovecot 1.0.10 with no issues for awhile now J. However I ran into an issue today where postfix didn't have enough processes to handle incoming smtp connections. This for whatever reason was causing pop/imap (dovecot) to take a long time to respond on the appropriate port. After looking at server and finding nothing wrong I stopped postfix which got rid of the delay on port 110/143. I then turned on postfix again and saw the delay for port 25/110/143. What I then did was adjust/increase the default_process_limit in postfix which took care of the problem. Question is why would not enough processes in postfix slow other services down like dovecot 110/143? There was plenty of bandwith/mem/cpu left.

[Dovecot] mailutil?
by Timo Sirainen 08 May '09

08 May '09

dbox format needs at least two tools: 1. Expunging only marks the message having refcount=0. The actual disk space is freed only after calling a tool pointing to the user's dbox dir. 2. Ability to force index resync/rebuild in case it doesn't figure out itself that there's something wrong. I'm starting to think about building a more generic mailutil tool, maybe something similar to what UW-IMAP has. So two questions: - What should the tool be called? Probably not mailutil to avoid confusion. doveutil? dovemail? dovetool? mailtool? - Is there any functionality you'd like it to do?

[Dovecot] Imap notifications in IDLE
by Jarosław Przybyłowicz 07 May '09

07 May '09

Hi, could you please tell me if there is a way, to make dovecot notify my mail client of new messages in inbox subfolders? I'm using fdm to fetch mails into maildir and proper subfolders. So far, when idleing mozilla gets a notification when new message arrives in INBOX, but if mail is fetched into other folder I have to click on it to see if there is a new message. I've checked thunderbird imap log to check if this is dovecot or TB issue. Is there any way to force dovecot to monitor other folders? Regards, V

[Dovecot] authentication to IMAP
by punit_j 07 May '09

07 May '09

HI All, Is there a way to do admin authentication for a normal user in dovecot IMAP ? I have a user using PAM to store password in /etc/shadow file. I need to authenticate the user in IMAP using that password. I tried using : - I tried all combinations as below [root@mail ~]# cat /etc/shadow| grep -i ajay ajay.lal:CM730q8foSA9A:13545:0:99999:7::: [root@mail ~]# telnet 0 143 Trying 0.0.0.0...

Escape character is '^]'. * OK dovecot ready. a1 login ajay.lal CM730q8foSA9A a1 NO Authentication failed. a1 login ajay.lal "{crypt}CM730q8foSA9A" a1 NO Authentication failed. Also i tried [root@mail ~]# perl -MMIME::Base64 -e 'print encode_base64("\0ajay.lal\0{crypt}CM730q8foSA9A");' AGFqYXkubGFsAHtjcnlwdH1DTTczMHE4Zm9TQTlB [root@mail ~]# telnet 0 143 Trying 0.0.0.0...

My dovecot server does PLAIN authentication as can auth_mechanisms = plain Is there a way to do PLAIN auth with crypt password or any means of doing admin authentication on behalf of normal user ?

[Dovecot] Solr FTS issues (Was fts-solr plugin issue (Marked invalid))
by Dror Matalon 06 May '09

06 May '09

Hi, Sorry for the change of thread, I just signed up to the list so I couldn't reply to the earlier message. Let me clarify the issue that Nikolai was describing. We're running dovecot 1.1.11 and solr 1.4. The issue is quite simple. 1. I run a search. 2. Dovecot sends a list of emails to solr 3. Solr starts indexing them 4. Solr runs into a "bad" email and we get: SEVERE: java.io.IOException: Mark invalid org.apache.solr.common.SolrException log SEVERE: java.io.IOException: Mark invalid at java.io.BufferedReader.reset(BufferedReader.java:485) at org.apache.solr.analysis.HTMLStripReader.restoreState(HTMLStripReader.java:171) at org.apache.solr.analysis.HTMLStripReader.read(HTMLStripReader.java:728) at org.apache.solr.analysis.HTMLStripReader.read(HTMLStripReader.java:742) at java.io.Reader.read(Reader.java:123) at org.apache.lucene.analysis.CharTokenizer.next(CharTokenizer.java:109) at org.apache.lucene.index.DocInverterPerField.processFields(DocInverterPerField.java:159) at org.apache.lucene.index.DocFieldConsumersPerField.processFields(DocFieldConsumersPerField.java:36) at org.apache.lucene.index.DocFieldProcessorPerThread.processDocument(DocFieldProcessorPerThread.java:234) at org.apache.lucene.index.DocumentsWriter.updateDocument(DocumentsWriter.java:765) ... 5. All the above email messages that were indexed are rolled back, and we're stuck. I think that the solution should be simple too :-). When solr runs into a bad email, it should just ignore it and keep indexing. This seems much more robust since the emails are coming from a variety of sources, and we can assume that some of them are going to generate badly formated emails. Seems like having a few bad emails not indexed is much better than the current situation of a bad email stopping all searching. I don't understand the architecture enough between fts, fts_solr and solr to know where this should be solved. Ideally, it would be a simple directive to solr.

[Dovecot] [OT] two-way IMAP synchronization
by Wolfram Schlich 06 May '09

06 May '09

Hi, I am looking for a tool that does a true two-way synchronization (synchronization of expunges/deletes) of IMAP mailboxes, kind of a mixture of unison and imapsync. Does anyone have any ideas how to accomplish that? TIA. -- Regards, Wolfram Schlich <wschlich(a)gentoo.org> Gentoo Linux * http://dev.gentoo.org/~wschlich/

[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)? Kind regards -- Kenneth Kalmer kenneth.kalmer(a)gmail.com http://opensourcery.co.za @kennethkalmer

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?

[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.

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] Maildir bugs
by Timo Sirainen 04 May '09

04 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.

[Dovecot] Problem with BODYSTRUCTURE (wrong charset)
by Craig Craig 04 May '09

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.

[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

Hi i'm using dovecot with virtual users from a postgresql database backend on a Debian Lenny system. I'm using qmail as MTA.

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.

[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? Thx. rick Rick Steeves http://www.sinister.net "Life is like a sausage: The more you pack into it, the longer it gets"

[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!

I just tested the quota-warning, with the dovecot-deliver-example.

[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).

I have dovecot (with squirrel mail etc.) running without any problems but cannot understand how to get e-mail from a pop server into dovecot. I have fetchmail configured to pick up the mail from the pop3 server but don't understand how to get it from there into my dovecot mbox structure. New to mail servers! Thanks, Michael.

[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
by Brandon Lamb 28 Apr '09

28 Apr '09

Hello, I finally got an INBOX to work, but is virtual mailbox plugin only meant to create a virtual inbox, or should I be able to have an Allmails virtual folder that is viewable in my imap client? if ~/virtual/ is my location, would I create an Allmails directory in the virtual/ or virtual/INBOX/Allmails.

[Dovecot] Dovecot auth user lookup patch for maildrop
by mr.maX 26 Apr '09

26 Apr '09

Hi, recently I started using maildrop as a MDA doing lightweight filtering in a Postfix/Dovecot mail server combo. Only thing missing was the fact that maildrop couldn't perform user lookups against a user database that was already being served by Dovecot (for smtp auth in Postfix and for imap access obviously) in order to easily determinate proper mailbox location and home directory of my "virtual" users when delivering e-mails. I wanted to avoid having another authentication daemon running (Courier Authlib) that would be serving this data to maildrop, so I've spent some time to write an extension for maildrop that would allow it to do user lookups directly against Dovecot in a similar way how they are done by Dovecot's LDA deliver. For everyone that are using maildrop in a similar setup that may be interested in this extension, a patch against maildrop version 2.0.4 can be downloaded from the following location: http://www.max.rs/ozone/maildrop-2.0.4-dovecotauth.patch.txt When this patch is applied, maildrop will be extended with another command line option "-t", which can be used to specify the location of Dovecot's master auth socket that will be used when performing user lookups. There's a readme file (README.dovecotauth) together with patch with a little bit more information regarding the use of this extension. I hope that some of you may find my modification to maildrop useful. -- Best Regards, Marko Njezic - mr.maX @ MAX Interactive corp.

[Dovecot] Virtual mailboxes, howto, examples, help? =)
by Brandon Lamb 24 Apr '09

24 Apr '09

Using 1.2rc3 maildir format maildir /mail/example.com/j/johndoe/{cur,new,tmp} Is there more documentation and examples on how to configure virtual mailboxes, or maybe more info on what it is suppose to do? From what I could understand on the wiki, i could create a fake/virtual folder under /mail/example.com/j/johndoe/virtual/allmail/ and inside that dir create dovecot-virtual with INBOX all And then in my mail client i would see virtual/allmail and when i click that folder it shows me mail from all my normal maildir folders? Is my thinking of how to use virtual mailboxes totally off, or am I trying to use it for what it is suppose to be used for? So far i have been messing with various values = yes/no using the following namespace private { prefix = virtual/ separator = / # location = virtual:~/virtual location = virtual:~/virtual:LAYOUT=maildir++ list = yes inbox = no subscriptions = yes hidden = no } # The default namespace that is visible to IMAP clients namespace private { prefix = separator = / location = maildir:~/ list = yes inbox = yes subscriptions = yes hidden = no } I dont know if I am retarded in my lack of ability to figure this out or what

I am starting to use Squirrelmail a little bit more to read my mail during the day and I seem to be getting this error more frequently while using Squirrelmail.

[Dovecot] bad maildir location
by denis 23 Apr '09

23 Apr '09

Hi, I use dovecot 1.0.15 on Debian Lenny. In my /etc/dovecot/dovecot-sql.conf, i use user_query = SELECT path, 33 AS uid, uid AS gid FROM mail_users WHERE alias = '%u' The result is something like this /var/alternc/mail/d/denis_collectifs.net and is the correct location (the Maildir is created by an script) But the problem is that dovecot creates (when you log in for the first time) a directory in the form of the exact address. Here for example, /var/alternc/mail/d/denis(a)collectifs.net And so all connections will be on an empty location. How is it possible to resolve this? As mail_location I have this "maildir:/var/alternc/mail/%1u/%u/Maildir" which is not really correct. Thanks Denis PS: For now, I temporarily symlinks /var/alternc/mail/d/denis(a)collectifs.net /var/alternc/mail/d/denis_collectifs.net

[Dovecot] server is not imap4 compatible
by marco ghidinelli 23 Apr '09

hello, i have a problem with my dovecot installation. sometimes, the thunderbird clients on windows machines complains about: "server is not imap4 compatible". on the server, at the same time, i found this error: Apr 20 16:21:17 harlock dovecot: imap-login: Disconnected: Shutting down: rip=192.168.0.194, lip=10.70.0.1, TLS handshake the imap server is behind a dmz which sometimes drops connections. the server ran without problem until i upgraded from 1.0.rc15 to 1.0.15. after the upgrade i was forced to enhance the proc.sys.fs.inotify.max_user_instances = 1024 because i had error messages about "Inotify instance limit for user exceeded" my question is: does the upgrade triggered a new way of communication between clients and server that exacerbates the problem of dropped connections from the DMZ server? p.s. the dovecot configuration is: $ sudo dovecot -n # 1.0.15: /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s ssl_cert_file: /etc/ssl/certs/harlock_digicert_2009.pem ssl_key_file: /etc/ssl/private/harlock_digicert_2009.key login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login login_max_processes_count: 256 mail_privileged_group: mail mail_location: maildir:/var/mail/vhosts/turboden.net/%n/ 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 imap_client_workarounds(default): tb-extra-mailbox-sep imap_client_workarounds(imap): tb-extra-mailbox-sep imap_client_workarounds(pop3): outlook-idle pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv auth default: mechanisms: plain login default_realm: DOMAIN.LOCAL username_format: %Ln@%Ud passdb: driver: pam userdb: driver: static args: uid=5000 gid=5000 socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix

[Dovecot] Mailbox is locked?
by Kyle Wheeler 23 Apr '09

23 Apr '09

Hello, I recently upgraded from Dovecot 1.1.8 to 1.1.14, and I've started to get errors I never got before. Specifically, I'm getting "Mailbox is locked, will abort in xx seconds" errors. My mail client (mutt) will just sit there in the background (presumably in IDLE) and randomly will show this error (I THINK it has something to do with delivering new messages to the folder; I use the dovecot LDA). Nothing else about my configuration has changed, just the version of dovecot. Does anyone know what could be causing these? I assume it has something to do with the index files, but... Nothing interesting shows up in the log files. How do I get rid of these error messages? Or even begin tracking them down? For what it's worth, mail is stored on the server in Maildirs, and the lock_method is fcntl, the mbox_write_locks is fcntl (I don't set mbox_read_locks). ~Kyle -- For to accuse, requires less eloquence, such is man's nature, than to excuse; and condemnation, than absolution more resembles justice. -- Hobbes, Leviathan

[Dovecot] overnight clients causing lockfiles to be converted to root-owned messages on debian lenny
by Brett Dikeman 23 Apr '09

23 Apr '09

Greetings all, After running for more than a year without issue on debian lenny while it was in the testing- we're now experiencing problems under Lenny/Stable. Dovecot now converts some sort of lockfile into messages, and they're owned by root. The result is a mess; clients can't read their mailboxes with the root-owned files, and when the file is changed to be owned by them, many mail clients don't like the zero-length message (Outlook being one major client with this "problem".) This happens to users who leave their email clients open overnight. I haven't found a cronjob that could be responsible for this. Further details- 64 bit machine, we use maildir, /var/spool/mail is on an xfs volume, and we run postfix, procmail, and spamassassin. Dovecot version is 1.0.15; the machine is fully up-to-date with Debian Stable (Lenny.) Sample log entry of the aftermath; please pardon the sanitizing (host/username): Apr 22 00:08:34 host dovecot: IMAP(user): Fixed a duplicate: 1240289413.9181_0.host:2,S.lock -> 1240373314.P6717Q0M159857.host Apr 22 00:08:34 host dovecot: IMAP(user): Fixed a duplicate: 1240356531.15928_0.host:2,S.lock -> 1240373314.P9995Q3.host Apr 22 00:08:34 host dovecot: IMAP(user): open(/var/spool/mail/user/Maildir/cur/1240373314.P6717Q0M159857.host:2,) failed: Permission denied Brett

[Dovecot] expire-tool
by Jeff Rice 23 Apr '09

23 Apr '09

Hi, I'm having some trouble getting the expire plugin to work, and I'm not sure where to turn for troubleshooting. This is on 1.2rc3. To my dovecot.conf, I've added: mail_plugins = expire under the protocol imap and lda sections. I also added: dict { expire = mysql:/etc/dovecot/dovecot-dict-expire.conf } plugin { expire = Trash 30 Trash/* 30 Spam 30 expire_dict = proxy::expire auth_socket_path = /var/run/dovecot/auth-master } /etc/dovecot/dovecot-dict-expire.conf contains: -- connect = host=/var/run/mysqld/mysqld.sock dbname=email user=XXX password=XXX map { pattern = shared/expire/$user/$mailbox table = expires value_field = expire_stamp fields { username = $user mailbox = $mailbox } } -- I created the table and granted all permissions to the user. The socket is the same one used by the auth_socket process, so that should work. Dovecot restarts fine, but the table is empty. A couple questions: First, the mailboxes to expire are stored as user(a)domain/.INBOX.Trash. How should I list them in the conf file? Also, is there any way to have the system come up to date since older emails already exist in those boxes and should be deleted. Will it detect those, or only start to delete old emails that were delivered after the plugin was enabled? Second, should the table be empty if mail has been delivered & deleted since I enabled the plugin? I assumed it would start to fill. Jeff

[Dovecot] Quota for Shared Folders
by Anton Dollmaier 22 Apr '09

22 Apr '09

Good morning list, first of all: dovecot works really great, the performance is overwhelming (especially compared to courier), the configuration flexible as hell, it is good documented - I love this software. But as things get complicated, I think I need some additional help. I'm using dovecot to replace the currently used courier-mailserver in a shared hosting environment based on the control panel Confixx. Confixx uses per default filesystem-users, giving each mailuser a filesystem-quota, mails are stored in ~/Maildir/. The imap-logins are all in the form of "webxpy", being "webx" the customer (prefix 'web', and a increasing number), and "py" the number of the pop account. Because of the filesystem-quota we moved the indexes to another partition. This basic setup with dovecot works great, with auth directly against the confixx-database etc, imap_quota-plugin, quota-plugin working as expected. We now want to implement shared folders for each customer: all mailaccounts of a customer should be able to subscribe to per-customer shared folders in a specified maildir, thus I re-mapped the usernames with a new user_query (and password_query) to the format of "webxpy@webx" - being "webx" the virtual domain and "webxpy" the mailaccount, but still using "webxpy" as the imap-login (no need for customers to change the login). This also works, we even can control with ACL-vfiles the permissions of specified users, to enable or disable specific folders. The shared folders are specified as a new public namespace and the "domain" is part of the storage-path (see configuration at the end of this mail). To allow easier quota-management (no need to create a new system-user), the quota of the shared folders is maildir-based, with a mysql-quota-dictionary (later, all accounts will be migrated to a virtual-user-mailstorage, with only maildir-quota and no fs-quotas). But when things come to the shared quota, I currently don't know how to solve the wishes of the customer: The current solution for shared folders (at the customer's local site) is based on mdaemon, every shared folder (of a customer, not a single mail-account) has a quota assigned. This quota cannot be exceeded by the users, no more mails can be saved into the shared folders if used space exceeds the hard quota-value. As my tests have shown, dovecot uses a different approach to the quota-issue: users can always move their mails from local folders to the shared namespace, regardless of the shared quota. The quota itself is only checked when receiving new mails, where the combined quota (local + shared) may not be exceeded. If it is, the mail is not delivered to the mailbox. Our quota-config is this: > quota_rule: *:storage=50M:messages=1000 > quota_rule2: Trash:storage=50M:messages=100 > quota_rule3: shared*:storage=100M:messages=1000 (also being altered by user_query, but the scheme is the same) As of dovecot-wiki, this means: Users can save "50M + 50M + 100M" of mails in all specified Folders, so the storage-value for the "shared*"-folders works additionally to the "*"-storage-value. Different from this, we want the following to happen: If the customer exceeds the shared folders-quota, his mail-users may not move mails from INBOX to shared, this move-operation should fail with a reasonable error-message. If the local quota of a mail user is exceeded, new mails should be rejected/delayed, regardless of the shared quota-value (e.g., shared quota exceeded, but no local mails [new mail-account], mails should be delivered to INBOX). Sieve-filters are not a problem, we do not allow user-specific sieve-rules (managesieve is disabled). Hopefully, I could explain my issues to you. Our current dovecot-configuration is attached to this mail, any help would be gladly appreciated. If additional configuration-values/information is needed, I'll happily provide them, if possible. best regards, Anton Dollmaier > # 1.1.13: /etc/dovecot/dovecot.conf > # OS: Linux 2.6.26-1-686 i686 Debian 5.0.1 > log_timestamp: %Y-%m-%d %H:%M:%S > protocols: imap imaps pop3s pop3 > listen: *, [::] > ssl_cert_file: /etc/dovecot/dovecot.pem > ssl_key_file: /etc/dovecot/dovecot.pem > 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_max_userip_connections(default): 25 > mail_max_userip_connections(imap): 25 > mail_max_userip_connections(pop3): 10 > first_valid_uid: 249 > mail_access_groups: poponly > mail_privileged_group: poponly > mail_location: maildir:~/Maildir:INDEX=~/index:CONTROL=~/control > mail_debug: yes > mail_executable(default): /usr/lib/dovecot/imap > mail_executable(imap): /usr/lib/dovecot/imap > mail_executable(pop3): /usr/lib/dovecot/pop3 > mail_plugins(default): quota imap_quota acl > mail_plugins(imap): quota imap_quota acl > mail_plugins(pop3): quota acl > mail_plugin_dir(default): /usr/lib/dovecot/modules/imap > mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap > mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 > imap_client_workarounds(default): netscape-eoh > imap_client_workarounds(imap): netscape-eoh > imap_client_workarounds(pop3): > pop3_client_workarounds(default): > pop3_client_workarounds(imap): > pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh > namespace: > type: private > separator: . > inbox: yes > list: yes > subscriptions: yes > namespace: > type: private > prefix: INBOX. > hidden: yes > subscriptions: yes > namespace: > type: public > separator: . > prefix: shared. > location: maildir:/var/mail/shared/%d/:INDEX=~/shared > list: yes > auth default: > verbose: yes > debug: yes > debug_passwords: yes > passdb: > driver: sql > args: /etc/dovecot/dovecot-sql.conf > userdb: > driver: sql > args: /etc/dovecot/dovecot-sql.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: 432 > user: vmail > group: vmail > plugin: > quota: dict:::proxy::quotadict > quota2: dict::%d:proxy::quota2dict > quota_rule: *:storage=50M:messages=1000 > quota_rule2: Trash:storage=50M:messages=100 > quota_rule3: shared*:storage=100M:messages=1000 > acl: vfile > expire: Trash 7 Spam 30 > expire_dict: proxy::expire > dict: > quotadict: mysql:/etc/dovecot/dovecot-dict-quota.conf > quota2dict: mysql:/etc/dovecot/dovecot-dict-quota2.conf (the two quota-dicts could probably be merged into one) /etc/dovecot/dovecot-sql.conf: > driver = mysql > connect = host=localhost dbname=confixx user=confixx password=p4ssw0rd > default_pass_scheme = CRYPT > password_query = SELECT CONCAT(account, '@', kunde) as user, longpw as password FROM pop3 WHERE (account='%u' and gesperrt='0' > user_query = SELECT CONCAT('/var/mail/vmail/', p.kunde, '/', p.account,'/') as home, 249 as uid, 249 as gid, CONCAT('*:storage=', p.maxkbhard) AS quota_rule, CONCAT('shared.*:storage=', k.shared_maxkb) as quota2_rule FROM pop3 AS p, kunden AS k WHERE k.kunde = p.kunde AND CONCAT(p.account, '@', p.kunde) = '%u' (quota-values in kilobytes) /etc/dovecot/dovecot-dict-quota.conf: > connect = host=localhost dbname=confixx user=confixx password=p4ssw0rd > table = dovecot_quota > select_field = current > where_field = path > username_field = username /etc/dovecot/dovecot-dict-quota2.conf: > connect = host=localhost dbname=confixx user=confixx password=p4ssw0rd > table = dovecot_quota_shared > select_field = current > where_field = path > username_field = username (tables are exactly as specified in dovecot-wiki)

[Dovecot] Dovecot -> Gmail (via POP Mail Fetcher)
by Neil 20 Apr '09

20 Apr '09

I'm trying to move my entire email store from my Dovecot installation (which I normally access via IMAP) into Gmail using Gmail's Mail Fetcher (which functions over POP); and I'm running into two problems: 1. Gmail only imported 78 out of 1000+ mails in my inbox, which I'm taking to mean that Dovecot is reporting only those 78 as new. How can I get Dovecot to send all mail over as new? 2. I can't be sure of this yet (since, due to #1, Gmail doesn't seem to be downloading everything), but I'm pretty sure Dovecot is only reporting my Inbox emails over POP; is there a way I can get all my mail, from all my folders, to stream in over POP? Thanks, Neil PS. I'm not leaving Dovecot entirely, I just need to have my mail in another place in case something happens to my server...

[Dovecot] Strange behaivour with extended characters
by Armando Soto Baeza 20 Apr '09

20 Apr '09

Hi there. I am using dovecot in almost all the mail servers I configure, but I have not noticed some problems till now, when I configured a server for a japanese language based customer. Now I know, the problem is not about this customer, but it seems to be a constant in all my servers (for some reason we did not noticed that before). The situation is like this. When receving mail with extended (not only japanese) characters in the subject, Outlook Express does not recognize them. Most of our users do not use OE, but most of the japanese do. This is not all. When extended chars are also in the body, they look well when the maqil still arrives, but if forwarded to another account, or when mail is an answer to another, extended characters are not well displayed. In some tests we have done, I found more or less the same is happening when using squirrelmail. The funny thing is that the problem dos not appear when using Evolution or Outlook (the MS Office component). I move some pamrs in dovecot.conf and get some results (before moving them, the problem extended to attachements), but still remains as described. Somebody has seen such a behaivour and solved it? I was thinking to change dovecot for another agent, but will be happier using dovecot. Any suggestion? Thanks in advice.

[Dovecot] [SIEVE: Redirect] Double ">" in forwarded envelop sender address => Gmail syntax error
by Toorop 20 Apr '09

20 Apr '09

Hi, Plateform: gentoo + qmail My deliver line is in a .qmail-USER file: |/var/qmail/bin/preline /usr/libexec/dovecot/deliver -f ${SENDER:-<>} -d user(a)domain.tld I notice that sieve implementation in Dovecot use double ">" for the envelop sender when there is a redirect command in sieve script. (i've tried preline -f, without -f ${SENDER:-<>},... but nothing change for the the envelop sender syntax, alway the double ">") And that fact breaks forwardin to Gmail. Gmail reply that there is a syntax error probably due to the double "<<" (<<address>> and not <address>) as we can see in the log behind: Dovecot logs: deliver(stephane@XXXX): Apr 20 16:06:44 Info: Sending a forward to <XXXX(a)gmail.com> with return path <<stephane@XXXXXX>> deliver(stephane@XXXXX: Apr 20 16:06:44 Info: msgid=<49EC816D.9090403(a)XXXXX.com>: forwarded to <XXXXX(a)gmail.com> qmail-send logs: 2009-04-20 16:06:44.877793500 info msg 14815541: bytes 1290 from <<stephane(a)XXXXX.com>> qp 17780 uid 89 2009-04-20 16:06:44.892303500 starting delivery 6356: msg 14815541 to remote XXXXX(a)gmail.com 2009-04-20 16:06:44.982424500 delivery 6356: failure: Connected_to_209.85.219.1_but_sender_was_rejected./Remote_host_said:_555_5.5.2_Syntax_error._1si7169155ewy.101/ 2009-04-20 16:06:44.982502500 status: local 0/10 remote 0/80 Is there something to do to fix that probleme ?

[Dovecot] 0 mails available even if mails in mailbox
by Raphael Thoma 20 Apr '09

20 Apr '09

Hello We are currently facing the problem, that dovecot doesn't return any messages (Pop3: +OK 0 messages) even if there are messages in the cur and new directory (maildir format). The logfile does not contain any information other than login/logout. After I deleted the dovecot.index file, all messages are available and everything works as expected. According to the wiki page [1] the main index file should be synchronized when the cur and new timestamps changed. I suppose this synchronization doesn't work correctly because the problem still existed after I changed the timestamps manually. Dovecot version: 10.0.14 Operating System: FreeBSD 7.0-RELEASE-p1 CPU Arch: amd64 Filesystem: NFS Clients: The problem exists on Pop3 and IMAP. It doesn't matter which client. I could reproduce the problem on outlook, thunderbird and even on telnet. Reproduced: +OK Dovecot ready. user user(a)domain.com +OK pass password +OK Logged in. list +OK 0 messages: After deleting dovecot.index: +OK Dovecot ready. user user(a)domain.com +OK pass password +OK Logged in. list +OK 20 messages: It seems to be a problem with the index-file from dovecot which doesn't seem to be synchronized. What could be the reason for this behaviour? How can we fix this issue for all customers? Kind regards Raphael Thoma [1] http://wiki.dovecot.org/IndexFiles

[Dovecot] dovecot deliver with sieve: Corrupted index cache file (in-memory index).cache: Broken fields for mail UID
by Mathias Gug 19 Apr '09

19 Apr '09

Hi, Running dovecot deliver 1.1.11 with a sieve script (dovecot-sieve 1.1.6 + changeset b9567e94b897) the following messages started to show up in the mail logs for some (spam) messages: deliver(mathiaz): Apr 18 19:03:06 Error: Corrupted index cache file (in-memory index).cache: Broken fields for mail UID 1 deliver(mathiaz): Apr 18 19:03:06 Error: Couldn't fix broken header unfolding deliver(mathiaz): Apr 18 19:03:06 Info: msgid=<01c9548a$f1666dfe$6c822ecf@pillarsx6>: saved mail to INBOX How serious are these?

[Dovecot] Suggestion: deliver should honor mail_log_prefix
by Mike Abbott 19 Apr '09

19 Apr '09

I can set the log prefix for imap/pop3 processes using mail_log_prefix but the log prefix for deliver is hard-coded. (I'm using 1.1.13.) Deliver should either honor mail_log_prefix or have its own setting (deliver_log_prefix?). What do you think?

[Dovecot] Released Sieve v0.1.5 and ManageSieve v0.11.4 for Dovecot v1.2.rc3 and ManageSieve v0.10.6 for Dovecot v1.1.14
by Stephan Bosch 18 Apr '09

18 Apr '09

Hello Dovecot users, This is a simultaneous release of new versions of Sieve-related software for Dovecot v1.1 and v1.2. Only the Sieve implementation itself has seen significant development. The ManageSieve packages only have small fixes and the ManageSieve patches are updated as usual to match the new Dovecot releases. Changelog Sieve v0.1.5: * Ported the implementation of the Sieve include extension to the latest draft. This means that the import and export commands are replaced by a new command called global. The import and export commands are now DEPRICATED and are mere aliases for the global command. The new specification also adds the :once modifier to the include command. The also newly specified global.* variable namespace is not implemented yet as support for variable namespaces is currently missing. * Did a major rework of the multiscript support for better error handling and made sure that persistent global scripts (sieve_before/sieve_after) are always executed, even when the user does not have a script of his own and a global default is missing. + Provided basic support for the environment extension. Currenly, the name, version and host items are useful. Others are pending. + Improved error message that is presented when an unknown Sieve extension is provided as argument to the require command. It now notifies the user that Sieve core commands do not need to be specified in require. - Fixed bug in includes at levels deeper than one. - Fixed bug in address matching that was caused by the failure to handle group specifications. In Dovecot, these are marked by address items with NULL elements, which causes a segfault if not considered. The group 'undisclosed-recipients:;' in particular triggered this bug. Bug reported by Bernhard Schmidt. Changelog ManageSieve v0.11.4 (Dovecot v1.2.rc3): * Adjusted to changes in the Dovecot signal handler API. Changelog ManageSieve v0.10.6 (Dovecot v1.1.14): - Fixed small problems in the login proxy support. -- The releases are available as follows: Sieve for Dovecot 1.2: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.5.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.5.tar.gz.sig ManageSieve for Dovecot v1.2 (package + patch): http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.4.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.4.tar.gz.s… http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.rc3-managesieve-0.11.4.diff… http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.rc3-managesieve-0.11.4.diff… ManageSieve + patch for Dovecot v1.1 (package + patch): http://www.rename-it.nl/dovecot/1.1/dovecot-1.1-managesieve-0.10.6.tar.gz http://www.rename-it.nl/dovecot/1.1/dovecot-1.1-managesieve-0.10.6.tar.gz.s… http://www.rename-it.nl/dovecot/1.1/dovecot-1.1.14-managesieve-0.10.6.diff.… http://www.rename-it.nl/dovecot/1.1/dovecot-1.1.14-managesieve-0.10.6.diff.… -- Have fun testing the new releases and don't hesitate to notify me when there are problems.

[Dovecot] Mail replication
by Renaud Allard 18 Apr '09

18 Apr '09

Hello, I am running an asynchronously replicated mail setup. 2 servers are each running an smtp server which uses dovecot as the LDA. I am using unison to replicate mail files between servers. Before, I was using Maildir format and after reading so much good papers about the very good performance of dbox format, I decided to switch to dbox. However, I now have a very annoying problem, as mails are created with names like u.1234 and numbers are following each others. So, if there is for example a mail stored as u.1001 on both servers, and now 2 mails arrive at about the same time, 1 on each server. Then, they will both be created as u.1002, that means unison will encounter a conflict as both files are different. So my question would be, is there a way to tell the servers to increment by 2 instead of 1 and have each an offset (like you can do with mysql with auto incrementing tables for example)? That way, with former example, one mail would be stored as u.1002 and the other as u.1003. Thanks

[Dovecot] Logging to see exactly all IMAP commands?

[Dovecot] Feature Request: Control over IMP IDLE 'OK Still Here' message timings
by Robert Goldsmith 18 Apr '09

18 Apr '09

Hi all, I would like to make a feature request regarding IMAP Idle support. Currently when a client triggers Idle support, Dovecot then sends 'OK Still Here' messages every 2 minutes. This is apparently to prevent NAT systems killing the tcp connection and disconnecting the client. However, while this may be fine for desktop clients, this rapidly drains the battery life of mobile clients such as phones. Unfortunately, the timing control on this behaviour is a c define at the top of cmd-idle.c and is only adjustable at compile-time. I have experimented with this define and find a timeout of 20 minutes between 'OK' messages is perfectly adequate for my system setup and results in a significant battery saving for my Nokia 6120c (increasing from ~ 6 hours to ~ 55 hours from full charge to low battery warning). Therefore, can you please make the timeout changeable from the config file, even if it defaults to the current 2min timing, so admins supporting mobile users can balance battery life with a need to prevent killed tcp connections. Thanks Robert Goldsmith --- GnuPG public key: http://www.Far-Blue.co.uk

[Dovecot] Shared folders and subscriptions
by Markus Werner 18 Apr '09

18 Apr '09

Hi, I've got a problem with user shared folders and subscriptions. When I try to subscribe a folder, dovecot returns "OK Subscribe completed", but the newly subscribed folder is not listed with LSUB: a1 login test(a)example.com ******* a1 OK [CAP..... a2 list "" "*" * LIST (\HasChildren) "/" "INBOX" * LIST (\Noselect \HasChildren) "/" "#User" * LIST (\Noselect \HasChildren) "/" "#User/markus(a)example.com" * LIST (\HasNoChildren) "/" "#User/markus(a)example.com/ForTest" a3 subscribe "#User/markus(a)example.com/ForTest" a3 OK Subscribe completed. a4 lsub "" "*" * LSUB (\Noselect) "/" "#User/markus(a)example.com" Dovecot is 1.2-rc3, namespace configuration as follows: namespace private { separator = / prefix = INBOX/ inbox = yes subscriptions = yes } namespace public { separator = / prefix = "#Shared/" location = maildir:/var/spool/dovecot/sharedfolders:INDEX=~/Maildir/index/public:CONTROL=~/Maildir/control/public subscriptions = yes } namespace shared { separator = / prefix = "#User/%%u/" location = maildir:%%h/Maildir:INDEX=~/Maildir/index/shared/%%u:CONTROL=~/Maildir/control/shared subscriptions = yes list = yes } I tried without CONTROL= directory in the shared namespace, but that made no difference.

[Dovecot] Sieve "redirect"
by James Butler 18 Apr '09

18 Apr '09

Is there an alternative to the "redirect" Sieve capability? For example: if header :contains "Subject" "Listserv" { redirect "list-user1(a)example.com"; redirect "list-user2(a)example.com"; redirect "list-user3(a)example.com"; stop; } How can I do the above without using "redirect"? Unfortunately, "redirect" seems to be unsupported by Dovecot. Thank you. James

[Dovecot] Address Extensions with System Users
by Jeff Grossman 18 Apr '09

18 Apr '09

I am using Dovecot 1.2RC2 with Postfix 2.5.5. Everything is running fine. I would like to start using address extensions and have e-mail automatically filtered into folders based on the folder name after the "+" in the e-mail address. I only use system users, no virtual users. I have Deliver configured in main.cf as: mailbox_command = /usr/local/libexec/dovecot/deliver Everything I can find about setting this up applies to virtual users which I do not have. How do I get Deliver to recognize the address extension. I am sure it is easy, and I apologize for not finding the answer out myself. Here is a copy of my dovecot -n output: # 1.2.rc2: /usr/local/etc/dovecot.conf # OS: Linux 2.6.29-1-amd64 x86_64 Debian squeeze/sid base_dir: /var/run/dovecot/ protocols: imap imaps pop3 pop3s ssl_cert_file: /etc/ssl/certs/stikman-godaddy.crt ssl_key_file: /etc/ssl/private/stikman-godaddy.key ssl_cipher_list: ALL:!LOW:!SSLv2 disable_plaintext_auth: no login_dir: /var/run/dovecot//login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login mail_location: maildir:~/Maildir mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 auth default: mechanisms: plain login passdb: driver: pam userdb: driver: passwd plugin: sieve: sieve

[Dovecot] Setup Question
by Jeff Grossman 17 Apr '09

17 Apr '09

I really want to try and get this plus addressing working correctly with Dovecot and Postfix. After doing some reading I think I am going to change my Postfix setup from mailbox_command to mailbox_transport. I have a few questions to make sure I am thinking correctly. All of my users are system users. Their mail is delivered directly to their "/home/<user>/Maildir" directory. Everything works great and I have no problems. Here is what I am thinking of doing. 1. Create a new vmail user and group. 2. Have all mail delivered for each user to the "/home/vmail/<user>/" directory. All mail will be owned by vmail, but that is okay since Dovecot is the only thing touching the mail files anyway. 3. Change the mail_location setting in dovecot.conf to "mail_location = /home/vmail/%u 4. Uncomment the auth_socket_path = /var/run/dovecot/auth-master setting in dovecot.conf 5. Switch Postfix's main.cf to use "mailbox_transport = dovecot" and put the following line in master.cf: 1. dovecot unix - n n - - pipe flags=DR user=vmail:vmail argv=/usr/local/libexec/dovecot/deliver -f ${sender} -d ${recipient} -n -m ${extension} 6.

[Dovecot] Active Directory LDAP authentication fails after a time
by noahisaac 17 Apr '09

17 Apr '09

Hi - I've got Dovecot version 1.0.7 running on a CentOS 5.2 machine. It's serving pop, imap and imaps and authenticating against an Active Directory machine. This all works fine at first, but after about two weeks or so, dovecot's authentication against AD starts to fail. All of dovecot's authentication attempts time out. I also have postfix on the same machine authenticating against the same AD, and it does not seem to experience this issue. If I restart dovecot, the authentication starts working again. I've gone over /var/log/maillog, but I don't see anything particularly useful. The only thing I really see is: dovecot: IMAP(noah): Disconnected for inactivity Here's some of the relevant portions of my configs: dovecot.conf auth default { mechanisms = plain passdb ldap { args = /etc/dovecot-ldap.conf } passdb passwd-file { args = /etc/dovecot/passdb master = yes } userdb static { args = uid=vmail gid=vmail home=/home/vmail/%u } user = root } dovecot-ldap.conf hosts = admachine.domain.com base = dc=domain,dc=com ldap_version = 3 auth_bind = yes auth_bind_userdn = DOMAIN\%u Does anybody have any ideas about why this is happening, or maybe just an idea about how to better troubleshoot it? If you need any more info, I'll be happy to provide it. Can I tell dovecot to be a little more verbose with it's log entries (I've already got auth_debug set to yes, but I'm not getting very much info)? Thanks!

[Dovecot] SELinux and "i_stream_read() failed: Permission denied"
by James Butler 17 Apr '09

17 Apr '09

Not a problem ... sharing a solution (this time)! Please correct my understanding of the process, if required. "i_stream_read() failed: Permission denied" is an error message generated when a large-ish file (>128kb in my case) is attached to a message that has been passed to Dovecot's deliver program when SELinux is being enforced. In my case, these messages are first run through Spamassassin, then passed to deliver, however the SELinux policy that is being violated relates to deliver, and not to Spamassassin, even though I do NOT generate the errors WITHOUT running Spamassassin. I'm not going to guess as to why that is. The policies below resolve the issue, and now large-ish (even LARGE) attachments come through without a whimper with Postfix+Spamassassin+Dovecot. The problem is that deliver is not running with the correct SELinux policy to be able to write to the global /tmp directory (in my case, after receiving the big attachment from SA), even if that directory's permissions allow it. (Bless you, SELinux!) Small-ish file attachments do not trigger this deliver functionality. Here's a complete error message, and its subsequent errors in the course of delivering a large-ish message+attachment: =================================================== deliver(user): unlink(/tmp/dovecot.deliver.. \ 1239836047.9469.46242b1037005551) failed: Permission denied deliver(user): copy: i_stream_read() failed: Permission denied deliver(user): read(mail, uid=1) failed: Permission denied deliver(user): read(mail, uid=1) failed: Permission denied deliver(user): msgid=: save failed to INBOX: Internal error occurred. \ Refer to server log for more information. [2009-04-15 17:54:07] =================================================== This is the final error series received before the policies were finally updated, and shows an error during deliver's attempt to "unlink()" (remove) the temporary file. Previous errors occurred during attempts to "stat()" and "creat()" (sic) the temporary files. Basically, the "dovecot_deliver_t" context needs to be able to create, read, write and remove files in the /tmp directory ("tmp_t" context). Below, I am pasting my "local_postfix.te" SELinux policy file. It includes instructions for using it, and for figuring out how to do other SELinux policy adjustments on your own. This is my COMPLETE Postfix+Dovecot SELinux policy group. I also have policies for Spamassassin, if anyone wants them. If you are running Sendmail or another MTA instead of Postfix, you can build on what you find below and establish your own policies. I hope this proves useful. Again, please feel free to correct any misunderstandings I may be promoting with this message. Use at your own risk, please! No guarantees ... it just worked, for me.

[Dovecot] UW-IMAP migration to namespaces
by Jernej Porenta 17 Apr '09

17 Apr '09

Hello, I am trying to migrate existing UW-IMAP installation to dovecot 1.1.14 and I am having troubles with namespaces. As you know UW-IMAP allows full system access to home directory of a user and you can set up dovecot to do that as well, but I would like to use namespaces. If I set my namespaces like this: namespace private { separator = / prefix = inbox = yes location = mbox:~/:INBOX=~/.mailbox hidden = yes list = yes } namespace private { separator = / prefix = mail/ location = mbox:~/mail prefix = mail/ hidden = yes } Everything is working fine, but I am seeing also all other files in home directory of a user, but this is annoying if you have users with public_html folder with millions of files in it. Dovecot indexing makes index.log file for every file seen in namespace, so you have several million index files for files that are not mailboxes. So I was wondering is there a way to skip certain directories in namespaces or a way to setup namespaces in a way, that you would have: - INBOX in home directory - some folders in home directory (via .subscriptions) - some folders in %h/mail/ directory - and not seeing all other files/directories in home dir Thanks in advance, regards, Jernej

[Dovecot] Multiple instances and/or separate certificates per email address
by Simon L Jackson 17 Apr '09

17 Apr '09

Hi, We have a mail server with multiple instances of Postfix each listening on a different IP address to create a set of virtual mail servers. There are various reasons why separate instances of Postfix seems to work best to achieve this goal, but I wont divert into that discussion here. I would like so match this with Dovecot. The listening side isn't a problem as Dovecot can listen on multiple explicit IP addresses. However, we would prefer a separate SSL certificate for each virtual mail server i.e. for each IP address. Would it be better to have multiple instances of Dovecot on the server (not sure what the issues might be with this) or would it be better/easier to be able to specify separate SSL certificates for each listen address, since there isn't any other reason I can see to have multiple instances. Any thought? Is there a way to do this now or would this be a new feature request?

I was already going to report a bug with rc2 where the server crashed when a client tried to access a Maildir folder with wrong permissions. After installation of rc3 the server correctly reports the wrong permissions and keeps running: IMAP(user1): stat(/var/spool/mail/user1/Maildir/tmp) failed: Permission denied (euid=12807(user1) egid=200(grp1) missing +x perm: /var/spool/mail/user1/Maildir) Great work, thanks Timo! -- Wolfgang Friebel Deutsches Elektronen-Synchrotron DESY Phone/Fax: +49 33762 77372/216 Platanenallee 6 Mail: Wolfgang.Friebel AT desy.de D-15738 Zeuthen Germany

[Dovecot] v1.1.14 and v1.2.rc3 released
by Timo Sirainen 17 Apr '09

17 Apr '09

http://dovecot.org/releases/1.1/dovecot-1.1.14.tar.gz http://dovecot.org/releases/1.1/dovecot-1.1.14.tar.gz.sig http://dovecot.org/releases/1.2/rc/dovecot-1.2.rc3.tar.gz http://dovecot.org/releases/1.2/rc/dovecot-1.2.rc3.tar.gz.sig Fixed lots of bugs in v1.2 related to shared mailboxes and virtual mailboxes. Keep on testing and sending bug reports and hopefully we'll get v1.2.0 release out soon. :) Also v1.3 branch has started and it's coming along nicely. Multi-dbox is working and looks like its performance is very nice. LMTP server is basically implemented, except master process doesn't start it. Adding the master code started becoming so annoying that I think I'll finally finish the master process rewrite, or at least the most important parts of it. So looks like v1.3 might become v2.0 after all. v1.1.14 2009-04-16 Timo Sirainen <tss(a)iki.fi> * IMAP: Don't allow APPEND to specify INTERNALDATE more than 2 hours into future. With Maildir future INTERNALDATEs may mess up incremental backups. - Date: header was always being added to cache file when saving messages, even if clients didn't really want it. This caused POP3-only users to have dovecot.index.cache file unneededly. - Character set conversion in specific mails may have caused Dovecot to allocate all the available memory (in default configuration dying after having allocated 256 MB). This happened only while searching messages. - Message address parser didn't handle empty group:; correctly. - imap/pop3-login: Don't crash when shutting down and destroying clients. - deliver wasn't using mail_access_groups setting. - mbox: When doing autodetection, if mbox didn't find an existing mail directory it just went and created it anyway, instead of failing the storage creation. - Fixed some error handling in maildir and index code. v1.2.rc3 2009-04-16 Timo Sirainen <tss(a)iki.fi> * IMAP proxy no longer simply forwards tagged reply from remote authentication command. It's now done only if the remote server sent a [resp-code], otherwise all failure strings are converted to Dovecot's "Authentication failed." to make sure that if remote isn't using Dovecot it won't reveal user's existence. + Quota roots can now specify which namespace's quota they're tracking. This is probably the most useful for giving public namespaces a quota. + Added imap_idle_notify_interval setting. - Fixes to shared mailbox handling - Fixes to virtual mailboxes - Fixed compiling with some FreeBSD and NetBSD versions - THREAD REFS still might have returned one (0) at the beginning. - deliver wasn't using mail_access_groups setting. - Fixed some error handling in maildir and index code.

[Dovecot] Postfix, Dovecot SASL and Entourage smtps authentication fails.
by Mart Pirita 17 Apr '09

17 Apr '09

Tere. Recently just migrated from Sendmail 8.14.3 to Postfix 2.5.6 and switched from Cyrus-sasl 2.1.22 to Dovecot 1.1.13 sasl, all are compiled from source and I have used Dovecot for a long time, since alpha versions. Everything worked well for Outlook Express, Outlook and Thunderbird clients, but Microsoft Entourage 2004 or 2008 clients smtps fails - "Authentication failed because Entourage doesn't support any of the available authentication methods." Similar case like - http://archives.neohapsis.com/archives/postfix/2008-09/thread.html#145 I tried everything, the config is like described in Postfix and Dovecot sites - http://wiki.dovecot.org/HowTo/PostfixAndDovecotSASL I also tried in main.cf smtpd_sasl_security_options =forward_secrecy like described in http://www.postfix.org/postconf.5.html#smtpd_sasl_security_options But none helped. So I switched back to Cyrus-sasl and Entourage works well like before with sendmail. I started to search what may be the reason, and seems with Dovecot sasl Postfix wont advertise needed stuff in ehlo: With Cyrus: telnet localhost 25 Trying 127.0.0.1... Connected to localdomain.localhost. Escape character is '^]'. 220 my.host.ee ESMTP EHLO example.com 250-my.host.ee 250-PIPELINING 250-SIZE 250-ETRN 250-STARTTLS 250-ENHANCEDSTATUSCODES 250-8BITMIME 250 DSN starttls 220 2.0.0 Ready to start TLS With dovecot: telnet localhost 25 Trying 127.0.0.1... Connected to localdomain.localhost. Escape character is '^]'. 220 my.host.ee ESMTP EHLO example.com starttls 220 2.0.0 Ready to start TLS Setting with Cyrus in main.cf smtpd_tls_auth_only = no gives even more but still nothing with Dovecot: telnet localhost 25 Trying 127.0.0.1... Connected to localdomain.localhost. Escape character is '^]'. 220 my.host.eeESMTP EHLO example.com 250-my.host.ee 250-PIPELINING 250-SIZE 250-ETRN 250-STARTTLS 250-AUTH PLAIN LOGIN 250-AUTH=PLAIN LOGIN 250-ENHANCEDSTATUSCODES 250-8BITMIME 250 DSN So is this a Entourage or Dovecot or Postfix bug? I really like to drop the Cyrus and use only Dovecot sasl. Any hint is welcome. -- Mart

Hi, Shared folders is ok now. and when I create a public folder follow the doc http://wiki.dovecot.org/SharedMailboxes/Public, I can not get the boxes listed. namespace: type: public separator: / prefix: public/ location: maildir:/home/data/public:INDEX=~/Maildir/public list: children # ls /home/data/public/ -a . .. dovecot-shared .test1 .test2 .test3 And then, I checked the shared folders created by 'setacl' command, and add a dovecot-acl-list file in the root public folder, ok, I got it. # cat /home/data/public/dovecot-acl-list 1239108915 test1 so, 'dovecot-acl-list' should be created manually or any other methods?

[Dovecot] Is there any more detailed docs about dict configuration
by Xueron Nee 17 Apr '09

17 Apr '09

Hi, I am looking for some help on dict configration. I'm trying to config shared and public mailbox, and use sql as acl backend. Here is my config: table: CREATE TABLE `shared_dict` ( `id` int(10) NOT NULL AUTO_INCREMENT, `from_user` char(50) NOT NULL, `to_user` char(50) NOT NULL, `status` int(10) NOT NULL DEFAULT '1', PRIMARY KEY (`id`), KEY `from_user` (`from_user`), KEY `to_user` (`to_user`) ) dovecot-dict-sql.conf map { pattern = shared/shared-boxes/user/$from/$to table = shared_dict value_field = status fields { from_user = $from to_user = $to } } dovecot.conf acl_shared_dict = proxy::shared_dict It works, and when i use 'setacl', it can add a record. All I want are some more detailed docs about the `pattern' line, and such as how to add a `group' function. :) Detailed on quota/expire dict configration are welcome, too. :) Thanks! -- Xueron Nee http://www.xueron.com

[Dovecot] Public mailboxes configuration to receive mails
by Didier Faugeron 17 Apr '09

17 Apr '09

Hello, I would like to know how to use Public mailboxes in my Dovecot environment (dovecot 1.2.beta4) Currently my dovecot server is only used for mailbox user. The Postfix master.cf is configured with the following line: "dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/libexec/dovecot/deliver -d ${user}" Both dovecot and postfix use LDAP requests for authentication and users data retrieving. However I don't use userdb database to get the users home directory but an userdb static instruction : "args = uid=vmail gid=vmail home=/data/maildir/%1Lu/%Lu allow_all_users=yes" I have configured my dovecot.conf to create a namespace Public, and it works fine: an user who have read/write access(ACL) to a public mailbox can subscribe to it and read/copy mails. My problem is to deliver mails in this public mailbox. I don't know how to do it. Therefore, first question: is it possible to deliver mails to a public mailbox through the LDA/Postfix ? If yes, please could you tell me how to configure LDA/Postfix and Dovecot in order to accept and deliver mails to users mailboxes and to public mailboxes ? I assume that the main modifications should be done in the master.cf of Postfix. Could you please specify and clarify what modifications are required ? Find below my dovecot -n output and dovecot-ldap.conf. Thank you in advance for your help and your feedback.

[Dovecot] Could sharing a folder with other users cause a loss of emails?
by Alfred Nutile 17 Apr '09

17 Apr '09

we are trying to figure out how and email box is not empty. All we did was /mail/user1 /mail/user2 /mail/shared ln -s /mail/shared /mail/user1/shared ln -s /mail/shared /mail/user2/shared Perms are fine and people where dropping emails in here fine. We added a third one and the user also right clicked in their IMAP client and added a subfolder. It was around that time they where gone. Could any of these actions cause that? PS it is not a mbox layout. Thanks!

[Dovecot] Coredump using virtual folder.
by Matthias Rieber 17 Apr '09

17 Apr '09

Hi, I'm using dovecot 1.2rc2 and I have the following issues with the virtual folder: 1. The virtual folders are flagged with \Noselect and at least thunderbird does not offer to select them. Adding them to the subscriptions file works fine and the folder can be used after that. 2. Two basic virtual work just fine like: $ cat virtual/all/dovecot-virtual INBOX INBOX.Ordner.work.archive.* all and $ cat virtual/unseen/dovecot-virtual INBOX unseen But the third one does not work: $ cat virtual/talk/dovecot-virtual virtual.all inthread x-references2 x-mailbox INBOX The IMAP Client says Unkown server error, the server logs look like this: ... dovecot: Info: IMAP(matthias): virtual: data=~/Maildir/virtual dovecot: Info: IMAP(matthias): fs: root=/home/matthias/Maildir/virtual, index=, control=, inbox= dovecot: Info: IMAP(matthias): Namespace INBOX.: Using permissions from /home/matthias/Maildir: mode=0700 gid=-1 <access happens here> dovecot: Info: IMAP(matthias): Loading modules from directory: /usr/local/lib/dovecot/imap dovecot: Info: IMAP(matthias): Module loaded: /usr/local/lib/dovecot/imap/lib20_fts_plugin.so dovecot: Info: IMAP(matthias): Module loaded: /usr/local/lib/dovecot/imap/lib20_virtual_plugin.so dovecot: Info: IMAP(matthias): Module loaded: /usr/local/lib/dovecot/imap/lib20_zlib_plugin.so dovecot: Info: IMAP(matthias): Module loaded: /usr/local/lib/dovecot/imap/lib21_fts_squat_plugin.so ... kind regards, matthias

by Tomasz Lutelmowski 16 Apr '09

16 Apr '09

Hello ! Is it possible to configure dovecot so it can use SQL authentication for set of domains, and ntlm authentication for one domain? In other words, I would like to authenticate all users (with user(a)domain.com as login) in SQL server, and if not found, then strip @windomain.com from login and fallback to pam->winbind authentication. So far i have in my dovecot.conf: auth_default_realm = windomain.com mechanisms = plain passdb sql { args = /etc/dovecot/dovecot-sql.conf } passdb pam { } passdb passwd { } userdb sql { args = /etc/dovecot/dovecot-sql.conf } userdb passwd { } userdb prefetch { } in pam.d/dovecot : auth required pam_nologin.so auth include system-auth-winbind account include system-auth-winbind session include system-auth-winbind With this configuration I can authenticate all users for virtual domains with logins user(a)domain.com - ok, then it fallbacks to pam - ok, but then it returns error (winbind uses only "user" or "DOMAIN\user" as login). After I set auth_username_format = %n I get opposite situation - I can authenticate users with pam, but I can't with SQL (it requires user@domain as login field). Unfortunately auth_default_realm = windomain.com is a must have (and most of the windows clients uses user(a)windomain.com as login anyway). Please help, I'm banging my head against keyboard since 3 days but still no idea how to do it. Best regards, Tomek

[Dovecot] dovecot SASL + Postfix no IMAP or POP3
by Roderick A. Anderson 16 Apr '09

16 Apr '09

A customer is suffering with an older version of a Windows "Mail Server" software that does not permit connections to _other_ ports (25 only). Several of the domains they host have users who's ISPs block port 25 so they can not send mail. They'd like to set up an outbound (relay?) SMTP server for those customers using per user(a)domain.tld authentication. Since I personally use Postfix with dovecot SASL I'd prefer doing the same for them. The only issue I see is how to "disable" IMAP and POP3 and use only the SASL authentication feature. I read that Timo is thinking to _someday_ :-) separate the SASL authentication from the rest of Dovecot, but in the mean time can I just leave out the IMAP and POP3 stuff from dovecot.conf, or is there a disable option? Of course I'll clamp the IMAP and POP3 ports down with iptables but it would be nice knowing Dovecot would just say go away or ignore those connections. Is anyone doing this or have any suggestions, thoughts, or ideas about it? \\||/ Rod --

[Dovecot] INBOX lost in virtual namespace
by Xueron Nee 16 Apr '09

Hi, I have set a virtual namespace to create Virtual POP3 INBOX follow: http://wiki.dovecot.org/Plugins/Virtual dovecot.conf: mail_location = maildir:~/Maildir # default namespace namespace private { separator = / prefix = list = yes hidden = no subscriptions = yes } # virtual mailbox, for pop3 namespace private { separator = / prefix = virtual/ location = virtual:~/Maildir/virtual:LAYOUT=maildir++ list = no hidden = yes } # Copy of the default namespace. We'll use this in dovecot-virtual file. namespace private { separator = / prefix = secret/ list = no hidden = yes subscriptions = no } # cat ~/Maildir/virtual/.INBOX/dovecot-virtual secret/* all but, the INBOX lost in secret/ namespace :( When list in IMAP: a1 list "" "*" * LIST (\HasNoChildren) "/" "Sent" * LIST (\HasNoChildren) "/" "Spam" * LIST (\HasNoChildren) "/" "Junk" * LIST (\HasNoChildren) "/" "Draft" * LIST (\HasNoChildren) "/" "Trash" * LIST (\HasNoChildren) "/" "INBOX" a1 OK List completed. a1 list "secret/" "*" * LIST (\HasNoChildren) "/" "secret/Sent" * LIST (\HasNoChildren) "/" "secret/Spam" * LIST (\HasNoChildren) "/" "secret/Junk" * LIST (\HasNoChildren) "/" "secret/Draft" * LIST (\HasNoChildren) "/" "secret/Trash" a1 OK List completed.

Oh, that was fun. Making the change below resulted in mail getting deferred with "Fatal: destination user parameter (-d user) not given" ... which apparently is caused by running deliver as 'root'! (http://archive.netbsd.se/?ml=dovecot-general&a=2008-02&t=6558196) So I am back to: -rwxr-xr-x 1 root dovecot 4044835 2009-04-03 13:52 deliver which doesn't produce the error and delivers the mail. Still no joy with Postfix+Spamassassin+Dovecot. This is unbelievably hard to get going. I started with the default installations of everything on a brand new system. I only made minimal changes as indicated by the docs. Then I made small changes as indicated by this and other mailing lists. I always reverted back to the original defaults between each effort. Now I'm just stumped. I'm not a newbie ... I've been administrating public servers for over 10 years, and using and working on the Internet since 1968! This is just the first time I've tried to use Postfix+Spamassassin+Dovecot. Previous installations have all used Sendmail+Spamassassin+Dovecot with zero issues. I want the benefits of using the Maildir storage system, but the past two weeks of trying to get this going are making me question whether that benefit is worth it. Can anyone please post their successful Postfix+Spamassassin+Dovecot setup for me to learn from? I would really appreciate it.

I've been messing with this for too long, now, and I'm blind to whatever's wrong. Or I'm simply being dense. Either way, I need help with a common issue. I'm trying to get Postfix+Spamassassin+Dovecot going on Fedora 10. (I'll get back to the global Sieve thingy soon, but I need to get this going, first.) When using the simple: mailbox_command = /usr/local/libexec/dovecot/deliver everything is cool, except there's no Spamassassin involvement, obviously. The problem shows itself when the Spamassassin user hands off to the recipient user and Deliver + the recipient user tries to access /var/run/dovecot/auth-master. Thank you for any insight you can provide. /var/run/dovecot: 755 root:dovecot /var/run/dovecot/login: 750 root:dovecot /var/run/dovecot/auth-master: 750 root:dovecot (I think. auth-master is a temporary file?

[Dovecot] uw-imap to dovecot conversion tool
by Joe Pruett 14 Apr '09

14 Apr '09

i plan to switch from uw-imap to dovecot on a couple of medium size systems and so i have written a conversion tool that understands mbox, mbx, and mix formats and converts to maildir format while trying to preserve uid info, keywords, flags, subscriptions, etc. it seems to work for me now, but i think some feedback might be useful. so if you have some files to convert and a desire to help, please download: http://www.spiretech.com/~joey/uw2dovecot.pl and give it a whirl. it is very sparsely documented right now but isn't too complex (yet). by default it copies your INBOX, mail dir, and .mailboxlist info into Maildir. those filenames can be overridden. i'd suggest running with -v to watch it. it requires that the output directory not exist before starting, so it should be relatively safe. it doesn't lock any files being read, so an active uw tree could cause it indigestion. it's designed to run while inbound mail and pop/imap sessions are disabled. it uses a few perl modules, but they should be standard with perl itself. it does do everthing in memory, so the largest message you have will be in memory and will be duplicated at least once as crlf pairs are replaced. also, this assumes you'll change the uid format in dovecot.conf to %08Xu%08Xv so that it doesn't change uids for the clients. send feedback to me and cc the list if you feel it useful. once this is stable, i'll get it added to the dovecot wiki.

[Dovecot] Handling ENFILE
by Mike Abbott 14 Apr '09

14 Apr '09

My mail server consumed all of its configured file table slots and started returning ENFILE ("Too many open files in system") for many operations. This wreaked havoc with dovecot-1.1.13. Here are some areas where dovecot should detect and more gracefully handle ENFILE error returns: 1. Deliver should report an error more helpful than "Unknown internal error" when fdatasync_path fails: deliver(user): Apr 10 14:53:20 Error: fdatasync_path(/Volumes/MailData/ user/new) failed: Too many open files in system deliver(user): Apr 10 14:53:20 Info: msgid=<...>: save failed to INBOX: BUG: Unknown internal error 2. Index files should not be fscked when they could not be opened due to ENFILE: Error: IMAP(user): open() failed with index file /Volumes/MailData/ user/.Deleted Messages/dovecot.index: Too many open files in system Warning: IMAP(user): fscking index file /Volumes/MailData/ user/.Deleted Messages/dovecot.index 3. Dovecot should not crash when mail transaction logs become corrupt, or appear to have become corrupt due to ENFILE. Here is a sequence of error messages from the log but I can't tell whether the IMAP ones up through the panic in the middle are all from the same process, or from different processes. deliver(user): Apr 10 14:55:32 Info: msgid=<...>: saved mail to INBOX deliver(user): Apr 10 14:55:54 Error: open() failed with index file / Volumes/MailData/user/dovecot.index: Too many open files in system deliver(user): Apr 10 14:55:54 Error: open() failed with file /Volumes/ MailData/user/dovecot.index.log.2: Too many open files in system deliver(user): Apr 10 14:55:57 Error: open() failed with index cache file /Volumes/MailData/user/dovecot.index.cache: Too many open files in system dovecot: Apr 10 14:56:08 Warning: IMAP(user): fscking index file / Volumes/MailData/user/dovecot.index dovecot: Apr 10 14:56:16 Error: IMAP(user): Fixed index file /Volumes/ MailData/user/dovecot.index: log_file_seq 15 -> 2 deliver(user): Apr 10 14:56:19 Info: msgid=<...>: saved mail to INBOX deliver(user): Apr 10 14:56:20 Error: Corrupted transaction log file / Volumes/MailData/user/dovecot.index.log seq 2: record size too small (type=0x0, offset=23088, size=0) (sync_offset=36848) deliver(user): Apr 10 14:56:20 Warning: fscking index file (in-memory index) deliver(user): Apr 10 14:56:21 Info: msgid=<...>: save failed to INBOX: Internal error occurred.

[Dovecot] Issue with converting users from cyrus user.domain.com
by Preston Lord 13 Apr '09

13 Apr '09

I have been using cyrus for the past 6 years, but it is a pain to config. So ... I just installed dovecot 1.0.15 on a new debian 4r7 box. In cyrus we were using usernames as "user.domain.tld". In dovecot I realize I can: auth_username_translation = .@ But this converts user.domain.tld to user@domain@tld which of course fails. Is there a regex or something I can apply to pull this off? I also tried auth_username_format = %n.%d But I think this does the opposite of what I need. Any help is GREATLY appreciated. Thanks in advance P.

[Dovecot] deliver vs lda
by Timo Sirainen 12 Apr '09

12 Apr '09

deliver is the binary name. but it's configured inside protocol lda {} section. This is getting annoying, any thoughts on what would be a good unifying name? a) deliver binary, protocol deliver {} b) lda binary, protocol lda {} c) dovecot-lda binary, protocol lda {} d) mda binary, protocol mda {} e) dovecot-mda binary, protocol mda {} f) something else? In any case protocol lda {} would work for a while longer for backwards compatibility. c) and e) choices also makes me think if e.g. imap and imap-login should be called dovecot-imap and dovecot-imap-login instead. People have had trouble finding them since ps|grep dovecot doesn't find them..

tonight dovecot 1.2beta4 crashed for the first time with an assertion failed. See attached log file. Around that time nobody was logged in into dovecot and there were no other mail deliveries going on. The mail in question should have been delivered to three recipients, one got the mail, the two others not. There is unfortunately no core dump file.

I'm trying to restrict imap logins to our internal network for several users, but this breaks dovecot delivery too Even if i set allow_nets to NULL or 0.0.0.0/0 deliver exits with "Error: Auth lookup returned failure" i'm running it as 'command = /usr/lib/dovecot/deliver -e -d "$local_part@$domain" -s' in exim.conf i guess delivery lookups should be independent of allow_nets i'm using dovecot 1.1.13 + managesieve patch -- Pavel

[Dovecot] outlook problem if TLS mailsettings are off

Behaviour: If I set /etc/dovecot/dovecot.conf: Following is valid with IMAP mailboxes only: disable_plaintext_auth = yes # outlook 2007 with TLS in/out enabled can show index of mails and klick on mail does preview / doubleklick opens mail PERFECT AS INTENDED disable_plaintext_auth = no # outlook 2007 with TLS/SSL OFF can show index of mails, but (double)-/klick on mail gives me "sandwatch"-mouspointer and I've to restart outlook again (and enable TLS again to get it work again) with POP3 mailbox both variants are working smoothly.

[Dovecot] Postfix + Dovecot + Sieve + SpamAssassin
by Sascha Scandella 10 Apr '09

10 Apr '09

Hello Until now I used Postfix in combination with Procmail and Dovecot. I am convinced that the Dovecot Sieve plugin is a much more elegant solution. So I changed to Postfix + Dovcecot Deliver + Dovecot + Sieve. If I understood correctly I cannot call other applications within a Sieve script. Until now I used Procmail to filter Spam Messages with SpamAssassin. Is there a possibility to filter spam messages before/after Dovecot deliver. I want to use the users .spammassassin user_prefs located in their home folder. I suppose if I use a content filter in Postfix this is to early, since the user is not known at that moment. Or am I wrong? Any help is highly appreciated. Best regards, Sascha

hi list, I'd like to know about "Status" to the header on dovecot.

Which one is the reason of that cannot see "Status" to the header with evolution and thunderbird? - there isn't "Status" to the header - there is "Status" to the header, but just cannot see Thanks in advance.

[Dovecot] dbox problem
by Xueron Nee 09 Apr '09

09 Apr '09

Hi, I have just tested the dbox format mailbox, it works fine. But when I create dir through imap with `create` command, it only creates the dir onder ~/dbox/mailboxes, such as ~/dbox/mailboxes/newfolder. There was no `dbox-Mails` dir created. So the newfolder was 'noselect'. But the new folders created by `autocreate` plugin was correct. -- Xueron Nee http://www.xueron.com

[Dovecot] Indexing of mails to speed up the IMAP SEARCH command
by Tassilo Horn 09 Apr '09

09 Apr '09

Hi all, I use a local dovecot server which is synchronized with my two imap accounts using OfflineIMAP. This works very nice and is highly usable. But one thing I'd like to improve is the slow IMAP search. When I search for a string in the subjects of all messages in a mailbox using some mail client, dovecot seems to grep all the messages in there. Is there a way to let dovecot index more informations which are then used to speed up the SEARCH command? Bye, Tassilo

[Dovecot] Moving IMAP folders to NFS volume.
by Frank Bonnet 09 Apr '09

09 Apr '09

Hello Due to lack of disk space on local disks I need to move all our imap folders to a NFS volume ( NetAPP filer ) I have a question about Dovecot indexes , is it better to remove all of them before copying folders to the NFS volume and let Dovecot rebuild all indexes when users restart to access to their imap folders ? Thanks a lot.

[Dovecot] Strange behavior of header_filter_callback

[Dovecot] Upgrade from 0.99.x to 1.1.x
by Wolfram Schlich 09 Apr '09

09 Apr '09

Hi! I want to upgrade a Dovecot installation from 0.99.14 to 1.1.15, so I had a look at the following wiki article: http://wiki.dovecot.org/Upgrading?action=show&redirect=UpgradingDovecot The article http://wiki.dovecot.org/Upgrading/1.0 says something about .customflags -> dovecot-keywords and .subscriptions -> subscriptions change/conversion: http://wiki.dovecot.org/Upgrading/1.0#Subscriptions http://wiki.dovecot.org/Upgrading/1.0#Keywords Do I understand it correctly that when directly upgrading from 0.99 to 1.1, Dovecot does the subscriptions renaming but not the keywords renaming and conversion, but that when I manually rename all .customflags files to dovecot-keywords, it does the format conversion of that file automatically? Is there anything else what's important to note for such an upgrade? The system is using Maildir as the mailbox format and only local storage (no NFS etc.). -- Regards, Wolfram Schlich <wschlich(a)gentoo.org> Gentoo Linux * http://dev.gentoo.org/~wschlich/

[Dovecot] Multiple use of the same LDAP attribute
by Bernhard Schmidt 09 Apr '09

09 Apr '09

Hi, we've found a weird bug (?) in Dovecot 1.1.11. Since day and age we've been running dovecot for our student mailserver, getting the location of the mailbox from a LDAP directory. We allow login and LDA with both full mail address and an internal username, so the mailbox directory is based on a LDAP attribute user_attrs = xxxMailbox=mail=maildir:/home/mailstore/%U$/Maildir:INDEX=/home/mailstore/indexes/%1U$/%U$, uidNumber=vmail, gidNumber=vmail, xxxMailQuota=quota_rule2=*:storage=%$B this worked just fine until we introduced sieve, which made us realize we did not have the home directory set at all. The obvious and easy fix (we thought) was to set the home directory based on the xxxMailbox variable as well: user_attrs = xxxMailbox=mail=maildir:/home/mailstore/%U$/Maildir:INDEX=/home/mailstore/indexes/%1U$/%U$, uidNumber=vmail, gidNumber=vmail, xxxMailQuota=quota_rule2=*:storage=%$B, xxxMailbox=home=/home/mailstore/%U$ unfortunately, after this trivial change hell froze over, because suddenly the mail variable was not set at all anymore, and since we had set mail_location = maildir:/home/mailstore/%Uu/Maildir:INDEX=/home/mailstore/indexes/%1Un/%Un (based on username) it was suddenly delivered into the wrong folder (based on the supplied username, not on the LDAP attribute). Debug from after the change: Apr 8 13:53:39 lxmhs23 dovecot: auth(default): ldap(username(a)xxx.de): user search: base=<deleted> scope=onelevel filter=<deleted> fields=xxxMailbox,uidNumber,gidNumber,xxxMailQuota,xxxMailbox Apr 8 13:53:39 lxmhs23 dovecot: auth(default): ldap(username(a)xxx.de): result: xxxMailQuota(quota_rule2=*:storage=%$B)=*:storage=1073741824B xxxMailbox(home=/home/mailstore/%U$)=/home/mailstore/1636D8B1D7916DEA/ [...] Apr 8 13:53:39 lxmhs23 deliver(username(a)xxx.de): maildir: data=/home/mailstore/USERNAME@XXX.DE/Maildir:INDEX=/home/mailstore/indexes/U/USERNAME As you can see the mail variable wasn't set by LDAP at all. We did some more tests and found a workaround, when using another LDAP (mwnid) attribute that contains the same information it works just fine user_attrs = xxxMailbox=mail=maildir:/home/mailstore/%U$/Maildir:INDEX=/home/mailstore/indexes/%1U$/%U$, uidNumber=vmail, gidNumber=vmail, xxxMailQuota=quota_rule2=*:storage=%$B, mwnid=home=/home/mailstore/%U$ Apr 8 14:18:06 lxmhs23 dovecot: auth(default): ldap(username(a)xxx.de): user search: base=<deleted> scope=onelevel filter=<deleted> fields=xxxMailbox,uidNumber,gidNumber,xxxMailQuota,mwnid Apr 8 14:18:06 lxmhs23 dovecot: auth(default): ldap(username(a)xxx.de): result: xxxMailQuota(quota_rule2=*:storage=%$B)=*:storage=1073741824B xxxMailbox(mail=maildir:/home/mailstore/%U$/Maildir:INDEX=/home/mailstore/indexes/%1U$/%U$)=maildir:/home/mailstore/1636D8B1D7916DEA//Maildir:INDEX=/home/mailstore/indexes/1/1636D8B1D7916DEA/ mwnid(home=/home/mailstore/%U$)=/home/mailstore/1636D8B1D7916DEA Apr 8 14:18:06 lxmhs23 deliver(username(a)xxx.de): maildir: data=/home/mailstore/1636D8B1D7916DEA//Maildir:INDEX=/home/mailstore/indexes/1/1636D8B1D7916DEA/ So, it looks like there is an issue using the same LDAP attribute (xxxMailbox in this case) twice in variable expansion. Is this a known issue? Of course there are several viable workarounds (base mail location on home directory, use the second attribute), but this problem was pretty surprising. Bernhard

[Dovecot] Trying nonplaintext mech with LDAP password-hash
by dovecotlist＠encambio.com 09 Apr '09

09 Apr '09

Hello List, The only passdb block in /pfx/etc/dovecot/dovecot.conf is: passdb ldap { args = /pfx/etc/dovecot/dovecot-ldap.conf } In /pfx/etc/dovecot/dovecot-ldap.conf: auth_bind = no dn = cn=mymgr,dc=host,dc=tld dnpass = ******** default_pass_scheme = LDAP-MD5 In /pfx/etc/openldap/slapd.conf: password-hash {MD5} If I try: $ /pfx/bin/ldapsearch <...> \ | grep '^userPassword' \ | sed -e 's;.*:: $.*$$;\1;' \ | mimencode -u ...I get the correct password (MD5 hashed.) According to wiki.dovecot.org/AuthDatabase/LDAP/PasswordLookups this should work, and indeed when starting dovecot it does not complain about: 'CRAM-MD5 mechanism can't be supported with given passdbs' Instead it starts right up, but when a thunderbird client connects and tries authenticating with CRAM-MD5 it fails. In the wiki page 'PasswordLookups' it mentions: Supports non-plaintext authentication mechanisms (if returning plaintext/properly hashed passwords). I've already verified that this works correctly with plaintext (CLEARTEXT in slapd.conf), but I really want to store the passwords in LDAP using some hash. Why doesn't LDAP-MD5 work as advertised? What did the author mean by 'properly hashed passwords'? Thanks. -- Eduard

Greetings - We are running Dovecot 1.1.11 on our servers and have been gradually migrating people off our old (UW-based) systems onto the new (Dovecot-based) ones. As a result the new systems are seeing more connections from more people. We have started seeing problems reported by users of our webmail service that they are getting an error indicating the webmail software (Prayer) has failed to establish an IMAP connection using TLS to Dovecot. Investigations show it is not just the webmail service that is affected but all mail clients: it's just other clients retry the connection, whereas Prayer fails the login and shows the error message: TLS/SSL failure for username.imap.york.ac.uk: SSL negotiation failed It seems to be related to one of Dovecot's imap-login processes getting a lot of file descriptors in use. We initially spawn off 10 imap-login processes and have each handling 256 connections. Full "dovecot -n" at the end of the message, but the relevant settings here are: login_process_size = 64 login_process_per_connection = no login_processes_count = 10 login_max_processes_count = 128 login_max_connections = 256 We have grown to suspect it is to do with one of the imap-login processes having a large number of files open. Killing the process seems to get rid of the problem. For example currently we have 11 imap-login processes running, one of which has 518 open files -- process 12436 in the list below. I suspect that, as in previous times we've encountered the problem, killing this process will alleviate the problem. (I'll be doing this later on this evening.) It is slightly odd that the imap-login processes have a very skewed distribution of open files, almost as if the algorithm for allocating connections to a process favours some over others. For example the current counts of open files are: Pid = Open files count 12430 = 42 26818 = 237 12431 = 90 12433 = 12 12438 = 304 12437 = 106 12435 = 190 12432 = 14 12436 = 518 12434 = 32 12429 = 12 Process 12436 was one of the 10 imap-login processes initially created back on March 3rd. (Process 26818 was the additional imap-login process spawned a little later on March 4th.) I don't believe the problem lies with the available file descriptors on the system: in the script which starts Dovecot I do date >/var/run/dovecot-limits ulimit -Sa >>/var/run/dovecot-limits echo "----------" >>/var/run/dovecot-limits ulimit -Ha >>/var/run/dovecot-limits ulimit -Sn 10128 echo "==========" >>/var/run/dovecot-limits ulimit -Sa >>/var/run/dovecot-limits echo "----------" >>/var/run/dovecot-limits ulimit -Ha >>/var/run/dovecot-limits $DOVECOT >>/var/run/dovecot-limits 2>&1 (The magic 10128 number came from Dovecot 1.1.11 itself, complaining that the number I had originally was too low.) Likewise the output of the pfiles command on process 12436 (which is the one I believe to be problematic) indicates its limit still has some available -- I'm guessing Dovecot has reduced the limit down to 533 from the 10128 set in the startup script: Current rlimit: 533 file descriptors We originally saw this problem with Dovecot 1.0.3 which we were running up until a couple of weeks ago. From there I upgraded first to 1.0.15 and then to 1.1.11. I'd hoped that upgrading would fix the problem: I see it has been mentioned before on the list, but not for a year or two. Can anyone give any help, please?

[Dovecot] Prohibit removing INBOX
by floss＠pbartels.info 08 Apr '09

08 Apr '09

Hello list, I'm using dovecot 1.1.11 and I'm going to prohibit users to remove their INBOX and some other directories in the mailbox root. I used Access Control Lists (http://wiki.dovecot.org/ACL) to do this: protocol imap { mail_plugins = acl } plugin { # With global ACLs in /etc/dovecot/acls/ directory: acl = vfile:/etc/dovecot/acls } /etc/dovecot/acls/.DEFAULT: owner lrwstie /etc/dovecot/acls/INBOX/.DEFAULT owner lrwstiekxa Actually - its not possible to create/remove directories under the mailbox root - its possible to create directories under INBOX - its NOT possible to remove directories under INBOX (This is my problem.) I tried symlinks like: /var/mail/.../INBOX/dovecot-acl -> /etc/dovecot/acls/INBOX/.DEFAULT /var/mail/.../dovecot-acl -> /etc/dovecot/acls/.DEFAULT But I think the symlink won't help because they doesn't change anything. And even with the symlinks its not possible to remove directories under IBOX. The documentation says: > If a mailbox has both global and per-mailbox ACL file, both of them > are read and the ACLs are merged. If there are any conflicts: > * v1.0 and v1.1: The per-mailbox ACL file overrides global ACL file. As far I can see it the documentation says nothing about merging ACLs of subdirs. But it seems the given behavior is not wanted by the dovecot design, because it seems it should be possible to override ACLs for subdirs, also give more permissions than the upper dirs. Is this a dovecot failure, do I miss something or is it really wanted by dovecot this way? My MUA (Evolution) says: > Cannot delete folder "INBOX/test". > Because "IMAP command failed: Permission denied". It unsubscribes the folder but it not able to remove it.

[Dovecot] Dovecot, LVS and the issues I have with it.
by neil 08 Apr '09

08 Apr '09

We run around 5 dovecot (debian etch 1.0.rc15) POP/IMAP 'nodes' using the LVS load balancer and an NFS based SAN. it works pretty well. I love the robustness of load balancing POP/IMAP. We do a reasonable amount of throughput through these especially at peak times pushing our SAN to around 1.5k IOP/s We currently have two issues with this setup. One of which is NFS index corruption issues we get due to NFS/dovecot locking. Basically the UUID list or a .index gets corrupt. This causes a full re-indexing of the mailbox / broken mailbox until i delete the indexes. In the UUID lists case the symptom tends to effect use who use POP rather than IMAP and insist on keeping messages on the server. Because it's corrupt it gets rebuilt one way or the other and the users email client proceeds to redownload the entire mailbox again until he remarks them to be saved. This tends to annoy the user a lot. After a bit of testing we do however expect this to be fixed by version 1.1. However if anyone has any comments on this I would certainly be interested. The other issue is a little tricky to describe or even log effectively. Occasionally a node basically receives more connections than it is able to handle. The connection count goes through the roof for that node. It will go up way beyond 150 dovecot authentication threads and 100 or so active POP/IMAP dovecot threads. The IO_wait/cpu and memory usage also tends to be spiking at this point. The server gets to the tipping point where it can no longer serve it's POP/IMAP requests fast enough compared to the number of connections it's getting. I'd be fine with this but this creates some less than desirable symptoms: 1. We obviously reach the auth thread cap eventually so any new auth requests basically get refused by the server. To the user this is a seen as an outlook/mail client re-auth pop-up request. This annoys them. Ideally if the server stops accepting auth requests it should fall off our load balancer until it can consistently accept them again. Since the LVS detects a node fail by whether the tcp port is still open this doesn't happen, since dovecot keeps the port open. This is obviously more an LVS issue and not for this mailing list I expect unless anyone has any config tweaking tips here? 2. Now here's my real gripe. Dovecot does not handle running out resources very gracefully at all in our setup. It does start killing threads after a while. I get multiple *"dovecot: child 17989 (login) killed with signal 9". *I'm not exactly sure what's going on here because after this all I can see is the machine totally out of memory and the kernel starts killing absolutely everything. All services are killed (including ssh etc..) and I plug a monitor into the server and find the last few lines of the console listing init and other rather important things having just been killed. At this point it is a case of power cycling the server and all is back to normal again. I imagine there's not a huge amount of people using dovecot in this way. But anyone got any recommendations here? I really like using dovecot in this setup it handles it pretty well and the redundancy and functionality options it provides have been invaluable. Neil

[Dovecot] Global Sieve File
by James Butler 08 Apr '09

08 Apr '09

Is anyone here using a global Sieve file that handles messages for an entire server with many users? I understand and use local Sieve files, but I would like to learn more about how to set up Sieve to filter ALL incoming messages using a single file. I would love to read about how you managed to get it working. I'm running Fedora 10 with Postfix 2.5.5 and Dovecot 1.2.rc2. Thanks for any insight! James

[Dovecot] Compiling v1.3 on different OSes
by Timo Sirainen 08 Apr '09

08 Apr '09

I was hoping to finally get shared libdovecot.so and libdovecot-storage.so libraries for v1.3, so Sieve (and maybe others) could link against them. But I'm running into trouble getting it to compile in Solaris 10. Could you non-Linux users test if this compiles with you? http://dovecot.org/tmp/dovecot-1.3.UNSTABLE.tar.gz Or if anyone has ideas why this happens, I'd like to know: libtool: link: gcc -std=gnu99 -g -O2 -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -Wstrict-aliasing=2 -I/home/cras/include -o .libs/rawlog rawlog.o ../lib-dovecot/.libs/libdovecot.so -lrt -lsocket -lsendfile -Wl,-rpath -Wl,/usr/local/lib/dovecot ../lib-dovecot/.libs/libdovecot.so: undefined reference to `dlerror(a)SUNW_1.22' ../lib-dovecot/.libs/libdovecot.so: undefined reference to `dlopen(a)SUNW_1.22' ../lib-dovecot/.libs/libdovecot.so: undefined reference to `dlsym(a)SUNW_1.22' ../lib-dovecot/.libs/libdovecot.so: undefined reference to `dlclose(a)SUNW_1.22' If I disable plugins (so dl*() functions aren't used) it compiles, so it's only those functions that are problematic. pvs -s /lib/libc.so lists the dl* functions under SUNW_1.22 so I'd think that should have worked..

[Dovecot] Segfault in dovecot 1.2rc2 with quota + public namespace enabled

[Dovecot] v1.3 plugin locations
by Timo Sirainen 07 Apr '09

07 Apr '09

It's getting more and more annoying to have separate plugin directories for lda, pop3 and imap. Currently all the plugins are installed into $lib/dovecot/ and then symlinked to the lda, pop3, imap directories. The original reason was that v0.99 just loaded everything in those directories since there was no mail_plugins setting. But then there are things like expire-tool and convert-tool (and the upcoming doveadm) that don't load plugins at all, even though they probably should. Adding just more directories to them seems to be pointless. Also SQL plugins are shared by dovecot-auth and dict and those would need symlinking.. And in future you might want to load SQL plugins to e.g. imap process. So, I was planning on just putting everything into $lib/dovecot/. expire-tool etc. would use mail_plugins setting that wasn't inside protocol {}. So for example: mail_plugins = quota protocol lda { mail_plugins = quota sieve } protocol imap { mail_plugins = quota imap_quota } protocol pop3 { # defaults to mail_plugins=quota above, no need to set it explicitly } That leaves auth and dict.. I was considering adding new auth_plugins and dict_plugins settings, but that might make it more difficult to start using distro-compiled Dovecot where sql, ldap, etc. are in plugins. So perhaps the auth/ and dict/ directories can stay and contain symlinks. But the $lib/dovecot/sql/ directory could go away and the sql plugins be stored just in $lib/dovecot/ among everything else. Any thoughts?

[Dovecot] Compile and configure Solr plugin
by Rui Carneiro 07 Apr '09

07 Apr '09

Hi all, I'm having some kind of troubles on Solr's integration. I configured Dovecot with the Solr argument (--with-solr) and everything proceeded just fine. But, when I started Dovecot I got this error: Plugin fts_solr not found from directory /usr/lib64/dovecot/modules/imap Error: imap dump-capability process returned 89 Fatal: Invalid configuration in /etc/dovecot/dovecot.conf In fact, there is no Solr plugin in that directory. So I tried to make a symbolic link from where the compiled Solr plugin was to this directory: ln -s /usr/local/lib/dovecot/lib21_fts_solr_plugin.so And now I have the following error: dlopen(/usr/lib64/dovecot/modules/imap/lib21_fts_solr_plugin.so) failed: /usr/lib64/dovecot/modules/imap/lib21_fts_solr_plugin.so: undefined symbol: mailbox_get_virtual_box_patterns Couldn't load required plugins Error: imap dump-capability process returned 89 Fatal: Invalid configuration in /etc/dovecot/dovecot.conf I'm missing some steps in this installation for sure, do anyone have any clue? Thanks, Rui Carneiro

[Dovecot] Modified websieve for use with dovecot
by Wolfgang.Friebel＠desy.de 07 Apr '09

07 Apr '09

In order to let users construct a sieve filter using a GUI I have taken websieve.pl from Alain Turbide (for use with Cyrus) and modified it to work with dovecot. In order to get it working quickly I have removed all the code I did not need (e.g. ldap support, password authentication) and coded Kerberos5 auth (via GSSAPI or SASL) in. I understand that this makes the work mostly useless to others. As however the dovecot adaptations were done by removing internally used perl packages by ones on CPAN such as Mail::IMAPClient and Net::Managesieve that part of the code should be of a broader interest. If someone is interested to have a look or even wants to help make it again a more universal tool I have put the code on ftp://ftp-zeuthen.desy.de/pub/unix/mail/websieve.pl Current status: I have tested the creation and modification of sieve rules, inspecting and setting ACL's (dovecot 1.2), displaying quota and creating folders. All the other code (e.g. the part that deals with an administrative user) is untested and probably not compatible yet with the new perl modules used. -- Wolfgang Friebel Deutsches Elektronen-Synchrotron DESY Phone/Fax: +49 33762 77372/216 Platanenallee 6 Mail: Wolfgang.Friebel AT desy.de D-15738 Zeuthen Germany

[Dovecot] Script to install dovecot 1.2 plus Managerootsieve to CentOS5.2
by Bruce A. Mallett 07 Apr '09

07 Apr '09

I have no idea if this is of interest to anyone but it might save you some work .. I created a script that will install Dovecot 1.2-rc2 (currently) to a CentOS5.2 installation complete with Stephan Bosch's Managesieve, postfix, virtual users, LDAP, and LDAP personal address books. Oh right! .. and Squirrelmail plus various plugins (change LDAP password, LDIF import, Avelsieve). Also self-signed certificates are created from data supplied in a configuration file. I've stuck the required files here: http://www.nightstorm.com/~bam/CentOS5.2/ I did an install to a 32 bit CentOS so it has worked at least once on that architecture. It *should* work on a 64 bit as well (I provide the RPM) but I've not personally tested it. I am by no means an expert on any of this stuff (particularly the security aspects), so I'd certainly welcome any suggestions for ways to improve on the installation, the script, life, the universe, ... ;-) - Bruce

Why is it listed with "\Noselect"? 2) "user/A(a)example.com/INBOX" does not exist, so the error message is correct, but why does it appear in the listing in the first place? cheers sascha -- Sascha Wilde OpenPGP key: 4BB86568 http://www.intevation.de/~wilde/ http://www.intevation.de/ Intevation GmbH, Neuer Graben 17, 49074 Osnabrück; AG Osnabrück, HR B 18998 Geschäftsführer: Frank Koormann, Bernhard Reiter, Dr. Jan-Oliver Wagner

[Dovecot] Implementation of editheaders in dovecot
by Konstantin Lepa 06 Apr '09

06 Apr '09

Hello. I wrote the hook function for deliver. I want to add support of editheaders in the plug-in for dovecot. For this purpose I wrote the function rarules_get_stream. Remover of headrs works properly, but adding does not work. I took Timo Sirainen's advice from http://markmail.org/message/skb6arnll5gaopdr . Do I use a correct way of creation of a message? I give backtrace and a part of my code.

[Dovecot] is it possible to recover files from a dovecot.inboxe.cache file?
by Alfred Nutile 06 Apr '09

06 Apr '09

I found this file in the mail boz and noticed it had 20 emails in it (though you can only read really the header the body is cryptic cause it is a bin file?) Just not sure if I can and how to use this to restore the lost emails in that inbox. Thanks

[Dovecot] Segfault in Sieve 1.2
by Bernhard Schmidt 06 Apr '09

06 Apr '09

Hello, two days ago I've upgraded to 1.2rc2 and the new sieve implementation (version 0.1.4). Today I got the first mail that got stuck in the postfix queue because deliver was dying with a segfault. The mail is spam, thus I don't have any issues sharing it: http://users.birkenwald.de/~berni/temp/deliver-segfault.mail It happens with this small sieve script (my normal one is larger, but this is the part that triggers the segfault): http://users.birkenwald.de/~berni/temp/deliver-segfault.sieve Note that I've been running this script unaltered for months, first with Dovecot 1.1 and CMUSieve and now with various versions of Dovecot 1.2 and the new sieve implementation for about three weeks, this is the first mail that got stuck. I got a coredump, but without debugging symbols it doesn't tell that much. If you can't reproduce it I'll compile it with debugging symbols and try again.

[Dovecot] THREAD X-REFERENCES2 index bug?
by Nathan Kinkade 04 Apr '09

04 Apr '09

Hi all, $ sudo dovecot --version 1.2.beta3 I just started using Dovecot a few weeks ago, and my client is also using the X-REFERENCES2 thread algorithm. The client is misbehaving when trying to list messages in my INBOX, but only when a threaded message exists. I have tracked it down to the thread index that Dovecot is returning, but the problem is only extant when using the X-REFERENCES2 thread algorithm. Here is a snippet of transcript from imap client that comes with Dovecot: $ export MAIL=maildir:~/Maildir:INBOX=~/Maildir/INBOX $ /usr/lib/dovecot/imap <snip> 1 SELECT "INBOX" <snip> 2 THREAD X-REFERENCES2 UTF-8 ALL * THREAD (0)(2)(1 3)(4) 2 OK Thread completed. There are, in fact, only 4 messages in my INBOX, and the reference to (0) seems spurious. When I do the same test, but passing REFERENCES instead of X-REFERENCES2 Dovecot returns an index which I believe to be correct: <snip> 2 THREAD REFERENCES UTF-8 ALL * THREAD (1 3)(2)(4) 2 OK Thread completed. <snip> Is this the normal and expected behavior of X-REFERENCES2 that the client just needs to take into account, or is the reference to thread index (0) an error? Thanks! Nathan

http://dovecot.org/releases/1.2/rc/dovecot-1.2.rc1.tar.gz http://dovecot.org/releases/1.2/rc/dovecot-1.2.rc1.tar.gz.sig I think it's time to get v1.2.0 out soon. Shared mailbox code is beginning to look like it's working and other features should work fine also. I don't really see any reasons to delay it, so please start testing and let's get the last bugs found and fixed quickly. I'm also going to start v1.3 branch soon with configuration rewrite and multi-dbox support. Changes since beta4: * Renamed THREAD X-REFERENCES2 to THREAD REFS (from INTHREAD draft) + When a process is killed, show the signal code and the sending process's pid and uid. + quota-fs: Added support for NFS group quota. - Several fixes to shared mailboxes and ACLs - Removed umask setting. We're nowadays creating practically all files with proper umasks. - acl: Dropped default ACL cache timeout from 5 minutes to 30 seconds. - fts-solr fixes - virtual mailbox fixes - Write to main index file less often.

[Dovecot] Missing mail_max_userip_connections setting
by Thomas M Goerger 03 Apr '09

03 Apr '09

Hi, I'm having a problem with a webmail client trying to open multiple IMAP connections with dovecot, and hitting a cap. I see from the error logs from this program that it's hitting the mail_max_userip_connections cap, but I'm not seeing this value as defined in the dovecot.conf file. Would this automatically get set to a certain value by default if it's not present?

[Dovecot] Maildir files with mtime in the future
by Holger Weiss 03 Apr '09

03 Apr '09

If Maildir storage is used, the mtime of a given Maildir file is set to the message's INTERNALDATE. Now, when a client APPENDs a message to an IMAP mailbox, the client may optionally specify the INTERNALDATE: | If a date-time is specified, the internal date SHOULD be set in the | resulting message; otherwise, the internal date of the resulting | message is set to the current date and time by default. [ ftp://ftp.fu-berlin.de/doc/rfc/rfc3501.txt (6.3.11. APPEND Command) ] However, if the client does so, Dovecot will set the mtime of the Maildir file in question to the date specified by the client even if it's in the future. Since files with an mtime in the future can cause all sorts of trouble (e.g., they might get backed up repeatedly by incremental backups), it would be nice if Dovecot would (optionally?) use the current time if the client specifies a time in the future. For example, we use the following patch: ---------- 8< ---------------------------------------- 8< ---------- diff --git a/src/imap/cmd-append.c b/src/imap/cmd-append.c index 0b22fd5..b7e42b9 100644 --- a/src/imap/cmd-append.c +++ b/src/imap/cmd-append.c @@ -319,6 +319,12 @@ static bool cmd_append_continue_parsing(struct client_command_context *cmd) return cmd_append_cancel(ctx, nonsync); } + if (internal_date != (time_t)-1 && internal_date > time(NULL)) { + /* the client specified a time in the future, set it to now. */ + internal_date = (time_t)-1; + timezone_offset = 0; + } + if (ctx->msg_size == 0) { /* no message data, abort */ client_send_tagline(cmd, "NO Can't save a zero byte message."); ---------- 8< ---------------------------------------- 8< ---------- Holger

Dear all, I am trying to setup Dovecot with GSSAPI support. For testing purposes gssapi is the only method allowed for login. As I cannot login to my mailbox, I'vo got two questions about the following log entries: dovecot: Info: auth-worker(default): passwd-file /dovecot/store/db/test-userdb: Read 3 users dovecot: Info: auth(default): new auth connection: pid=3915 dovecot: Info: auth(default): client in: AUTH 1 GSSAPI service=imap lip=131.169.*.* rip=131.169.*.* lport=143 rport=35779 dovecot: Info: auth(default): gssapi(?,131.169.40.218): Obtaining credentials for imap(a)my.host.name dovecot: Error: imap-login: Timeout waiting for handshake from auth server. my pid=3918, input bytes=0 1. I am puzzled about the credentials "imap(a)my.host.name" being obtained; shouldn't this be something like "imap/my.host.name(a)MY.REALM" ? 2. what does "Timeout waiting for handshake from auth server." mean? Who is trying to handshake with whom? Any ideas?

[Dovecot] Time moved backwards errors
by Bloke 03 Apr '09

03 Apr '09

Hello, I am experiencing a number of 'Time moved backwards errors' such as: Mar 27 11:38:20 host-78-129-239-60 dovecot: imap-login: Time just moved backwards by 729 seconds. This might cause a lot of problems, so I'll just kill myself now. http://wiki.dovecot.org/TimeMovedBackwards Mar 27 15:20:10 host-78-129-239-60 dovecot: Time just moved backwards by 4214 seconds. This might cause a lot of problems, so I'll just kill myself now. http://wiki.dovecot.org/TimeMovedBackwards Mar 29 11:08:59 host-78-129-239-60 dovecot: imap-login: Time just moved backwards by 4341 seconds. This might cause a lot of problems, so I'll just kill myself now. http://wiki.dovecot.org/TimeMovedBackwards on my Centos 5.2 openvz - based VPS I have raised the issue with my VPS provider, who are responding that 'the jury is still out' as to whether this is a system, or Dovecot problem. Reading the TimeMovedBackwards article on the Dovecot wiki, and the kernel mailing list thread referred to on it, it would seem quite apparent that this is caused by a failure of the gettimeofday() function to reliably return the correct value. If anyone has any advice as to how I could proceed to fix this (I currently have a watch on the Dovecot service which restarts it after any failures) or how I should best phrase this to get it resolved 'upstream' by the VPS provider, I would be very grateful. Thank you, Patrick Vale

[Dovecot] dbox benchmarks
by Timo Sirainen 03 Apr '09

03 Apr '09

http://hg.dovecot.org/dovecot-dbox-redesign/ Looks like multi-dbox scales pretty nicely. Even after 100k messages the peak saved msgs/sec is the same as the initial saved msgs/sec, even if the average slows down somewhat. I tested this by first deleting mailbox, then running "imaptest" for a second to get saving to start writing several fields to dovecot.index.cache file. Then ran imaptest for 60 seconds that did nothing but save messages using IMAP APPEND commands. The summary is that multi-dbox is almost 10x as fast as maildir when fsync is disabled and 2,5 faster with fsyncing: fsync_disable=yes: multi-dbox : ~1700 -> ~1500 msgs/sec, 90842 msgs/60 sec single-dbox: ~1700 -> ~1400 msgs/sec, 86149 msgs/60 sec maildir : ~330 -> ~110 msgs/sec, 9789 msgs/60 sec fsync_disable=no: multi-dbox : ~220 -> ~170 msgs/sec, 10113 msgs/60 sec maildir : ~100 -> ~70 msgs/sec, 4123 msgs/60 sec Also I just noticed that saving messages with two clients gets a peak of 2200 msgs/sec, most likely because two CPU cores can be used then. Hmm. I guess if there were no locking it should have reached 3400 msgs/sec, but it's better than no performance increase. And the raw data: multi-dbox, fsync_disable=yes imaptest clients=1 secs=1;imaptest clients=1 msgs=1000000 - logout=0 append=100,0 secs=60 Logi Sele Appe 100% 100% 100% 1 1 1759 1/ 1 0 0 1424 1/ 1 0 0 1734 1/ 1 ... 0 0 1701 1/ 1 0 0 1640 1/ 1 0 0 778 1/ 1 0 0 1305 1/ 1 0 0 1598 1/ 1 Totals: Logi Sele Appe 100% 100% 100% 1 1 90842 multi-dbox, fsync_disable=no imaptest clients=1 secs=1;imaptest clients=1 msgs=1000000 - logout=0 append=100,0 secs=60 Logi Sele Appe 100% 100% 100% 1 1 209 1/ 1 0 0 227 1/ 1 0 0 208 1/ 1 ... 0 0 203 1/ 1 0 0 145 1/ 1 0 0 156 1/ 1 0 0 180 1/ 1 0 0 162 1/ 1 Totals: Logi Sele Appe 100% 100% 100% 1 1 10113 maildir, fsync_disable=yes Logi Sele Appe 100% 100% 100% 1 1 331 1/ 1 0 0 311 1/ 1 0 0 288 1/ 1 ... 0 0 96 1/ 1 0 0 119 1/ 1 0 0 111 1/ 1 Totals: Logi Sele Appe 100% 100% 100% 1 1 9789 maildir, fsync_disable=no Logi Sele Appe 100% 100% 100% 1 1 77 1/ 1 0 0 101 1/ 1 0 0 45 1/ 1 ... 0 0 52 1/ 1 0 0 67 1/ 1 0 0 89 1/ 1 Totals: Logi Sele Appe 100% 100% 100% 1 1 4123 single-dbox, fsync_disable=yes imaptest clients=1 secs=1;imaptest clients=1 msgs=1000000 - logout=0 append=100,0 secs=60 Logi Sele Appe 100% 100% 100% 1 1 1765 1/ 1 0 0 1715 1/ 1 0 0 1764 1/ 1 ... 0 0 1722 1/ 1 0 0 1679 1/ 1 0 0 1678 1/ 1 0 0 828 1/ 1 0 0 1467 1/ 1 0 0 1469 1/ 1 0 0 1149 1/ 1 0 0 1135 1/ 1 Totals: Logi Sele Appe 100% 100% 100% 1 1 86149

[Dovecot] An issue of I login my mail server from webmail client
by Alan Zheng 03 Apr '09

03 Apr '09

Dear all: I have a really strange issue, that is when I login my mail server from webmail client (I used SquirrelMail, by the way, I have modified squirrelmail's timeout value, that means not since squirrelmail timeout), I will got timeout issue when I login about 5PM ~ 10PM everyday (it works fine on other time, I also check my cron, that looks no problem), and during this time, I also cannot connect my 993 port with openssl like this: openssl s_client -connect myDomainName:993 But when I use mail client (such as outlook) to access dovecot, that works fine, and during 5PM ~ 10PM, my web site also works fine, and once I restart computer if I can not login during 5PM ~ 10PM from webmail client. that will work fine. can you try to help me? below is my configure of dovecot. *dovecot -n # 1.0.7: /etc/dovecot.conf log_path: /var/run/dovecot/maillog info_log_path: /var/run/dovecot/maillog protocols: imaps ssl_parameters_regenerate: 0 verbose_ssl: yes login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login mail_location: maildir:~/Maildir mail_debug: yes auth default: mechanisms: plain login passdb: driver: pam userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix plugin: convert_mail: mbox:~/Mail:INBOX=/var/mail/%u* -- Best Regards Alan Zheng

[Dovecot] Dovecot ACLs
by dovecot＠corwyn.net 03 Apr '09

03 Apr '09

Running Dovecot 1.1.8 using Virtual users, multiple domains. My file structure is /var/spool/mail/<domain>/<user>/Maildir/ (cur, new,tmp,.Spam) What I'd like to do is add an ACL such that all users can read/delete/move mail that's in the spam folder, but not delete it. Am I going to have to create an entry for every single user, or is there a way to do it once, for all .Spam folders? I've read through http://wiki.dovecot.org/ACL and can't quite get this as the last step. Thanks rick Rick Steeves http://www.sinister.net "The journey is the destination"

Hello, I'am following the beginning tutorial on the Wiki, but actually, I can't even start the server correctly so far. The imap-login child dies immediately. What I can guess from the log is that it tries some unpermietted operations on some files but I can't find out which files are concerned. Google is not my friend at all either on this matter. How can I know which files are concerned ?

[Dovecot] Squat memory usage
by Ryan 02 Apr '09

02 Apr '09

I've been reading about using Squat with Dovecot on large mailboxes. I was wondering if some of the memory usage during searching and indexing could be reduced by using a berkeley db? I've used this in the past for something similar and in BTREE mode it was very fast for millions of keys. I havent had time to look at how squat is implemented, but I thought I'd throw it out there... -Ryan

Hi Timo, I'm playing with Dovecot v1.2.beta2 currently. When the dict process was started via deliver(?) and Dovecot is killed (kill $PID_OF_DOVECOT) after delivering only one message, it logs: Fatal: io_loop_handle_add: epoll_ctl(1, 10): Bad file descriptor If the dict process was not started or deliver has delivered more than one message, the error doesn't occur.

[Dovecot] quota-fs: get nfs GROUP quota (patch)
by fandorin＠rol.ru 02 Apr '09

Hi all. Unfortunately, the existing quota-fs does not know how to get GROUP quota with NFS storage. But there is a tool for Linux quota-tools (http://slackware.rol.ru/slackware/slackware-12.2/source/a/quota/) This patch is made on the basis quota-tools. The patch was successful alpha testing.
