[Dovecot] X-UIDL Ignored?
by Benjamin Wakefield 14 May '09

14 May '09

Hello! I am trying to migrate from Teapop to Dovecot. I'm using Dovecot 1.1.14. I need to make use of the X-UIDL header so clients don't download messages they've already received. I have the X-UIDL head in the message. I have pop3_reuse_xuidl(pop3): yes My problem is the X-UIDL in the message is being ignored and Dovecot is still generating it's own. The INBOX is an mbx file not Maildir. Should this work? Have I missed something? Thanks!

[Dovecot] virtual mailbox users users can send, but can't read e-mail
by Ioan Nemes 13 May '09

13 May '09

Greetings, I am trying to add the second virtual mailbox domain (transco.org.au) to an existing Postfix/Dovecot/MySQL mail server. Users of the first virtual mailbox domain (transylvania.org.au) have no problems sending and receiving mail. Users belonging to the second virtual mailbox domain can successfully send mail to outside, however they won't receive the mail, though Postfix delivers the mail to the mail directories. The configuration: --------------------------------------------------------------------------------------- # dovecot --version 1.0.2 --------------------------------------------------------------------------------------- # dovecot -n # 1.0.2: /etc/dovecot.conf base_dir: /var/dovecot/ protocols: imap imaps pop3 pop3s ssl_cert_file: /etc/ssl/dovecotcert.pem disable_plaintext_auth: no login_dir: /var/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 login_user: _dovecot first_valid_uid: 5000 last_valid_uid: 5000 mail_location: maildir:/var/spool/vmboxbase/%d/%u mbox_write_locks: fcntl 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 imap_client_workarounds(default): delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(imap): delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(pop3): outlook-idle pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: verbose: yes debug: yes debug_passwords: yes passdb: driver: bsdauth passdb: driver: sql args: /etc/dovecot-mysql.conf userdb: driver: passwd userdb: driver: sql args: /etc/dovecot-mysql.conf ---------------------------------------------------------------------------------------------------- password_query = SELECT password FROM users WHERE login = '%u' and active = 'Y' ----------------------------------------------------------------------------------------------------- SELECT password FROM users WHERE login = 'dummy(a)transco.org.au' and active = 'Y'; mysql> SELECT password FROM users WHERE login = 'dummy(a)transco.org.au' and active = 'Y'; +---------------+ | password | +---------------+ | Wdrbd5SLusraw | +---------------+ 1 row in set (0.00 sec) ------------------------------------------------------------------------------------------------------ user_query = SELECT home, maildir, uid, gid FROM users WHERE login = 'dummy' AND active = 'Y' ------------------------------------------------------------------------------------------------------ mysql> SELECT home, maildir, uid, gid FROM users WHERE login = 'dummy(a)transco.org.au'; +----------------------+-----------------------+------+------+ | home | maildir | uid | gid | +----------------------+-----------------------+------+------+ | /var/spool/vmboxbase | transco.org.au/dummy/ | 5000 | 5000 | +----------------------+-----------------------+------+------+ 1 row in set (0.00 sec) # more /etc/dovecot-mysql.conf # This file is opened as root, so it should be owned by root and mode 0600. # # http://wiki.dovecot.org/AuthDatabase/SQL # # For the sql passdb module, you'll need a database with a table that # contains fields for at least the userid and password.

Note that if you store username and # domain in separate fields, you most likely want to return a combination of # them as the "user" column, otherwise the domain gets stripped. # # Commonly used available substitutions (see # http://wiki.dovecot.org/Variables for full list): # %u = entire userid # %n = user part of user@domain # %d = domain part of user@domain # # Note that these can be used only as input to SQL query. If the query outputs # any of these substitutions, they're not touched. Otherwise it would be # difficult to have eg. usernames containing '%' characters. # # Example: # password_query = SELECT concat(userid, '@', domain) AS user, password FROM users WHERE userid = '%n' AND domain = '% d' # password_query = SELECT pw AS password FROM users WHERE userid = '%u' AND active = 'Y' # password_query = SELECT password FROM users WHERE login = '%u' and active = 'Y' # Query to retrieve the user information. # # The query must return only one row. Commonly returned columns are: # uid - System UID # gid - System GID # home - Home directory # mail - Mail location # # Either home or mail is required. uid and gid are required.

[Dovecot] Dovecot 1.0.7 domain variable
by elliott＠n.localhost 13 May '09

13 May '09

Hi all, Thanks in advance for any help! I'm trying to configure Dovecot to pull emails from Postfix virtual mailbox domain Maildirs under /var/mail/vhosts/<domain>/<username>. I've set mail_location as such in dovecot.conf: mail_location = maildir:/var/mail/vhosts/%d/%n but from debug output I see the domain is blank: dovecot: May 10 20:49:25 Info: IMAP(elliott): maildir: data=/var/mail/vhosts//elliott I've set elliott(a)n.0o0.bz as my username in Outlook so it is sending the domain (and changed auth_username_format to "auth_username_format = %n" so authentication works fine) Why is %d blank here? Anything else to check?? I'm at a loss. Thanks! -elliott-

[Dovecot] New messages notification - (IMAP PUSH?)

Hello all. I have strange problem. As I understand IMAP use server2client command to tell what new email is arrived. So - all was good, but few weeks ago I notice what my thunderbird not show new messages.

[Dovecot] Dovecot shared quota with Maildir
by Jorgen Lundman 13 May '09

13 May '09

Hello list, We are in the process of exploring the idea of moving from UFS with fs-quota to using softquotas in Dovecot (probably Maildir type, stored in LDAP, all ontop of NFS). I have it setup, and it works rather well so far. But there is one situation we can currently support, which I can not see a solution for with soft-quotas. Generally customers get 1 email, with 1 quota. But it is also possible for customers to get 1 quota, but create multiple mail accounts, all sharing the same quota. This is done by using the same UID for each account when using fs-quota. (It is not that each account gets a fraction of the quota, but that all accounts add up to the one quota). Is this still possible to do with soft-quotas. To share one set. Dovecot would have to go count files in multiple mail-directories so I would guess no.

[Dovecot] dovecot bug (maybe)

I believe that dovecot is doing something strange, when it founds a 'corrupted' multipart and using fetch body. Look what I figured out: 1) Sent a message from squirrelmail (it wrongly drop the last \n from epilogue): ------=_20090512171902_78105 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 8bit n ------=_20090512171902_78105 Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: 8bit n <--------(squirrelmail didn´t insert an additional \n). ------=_20090512171902_78105-- 2) Sent a correct message, inserting the last '\n': ------=_20090512171902_78105 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 8bit n ------=_20090512171902_78105 Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: 8bit n ------=_20090512171902_78105-- 3) Compress both messages 4) Request the messages using: A004 UID FETCH 1 (FLAGS BODYSTRUCTURE) (the correct message): 127.000.000.001.00143-127.000.000.001.35604: * 1 FETCH (UID 1 FLAGS (\Seen) BODYSTRUCTURE (("text" "plain" ("charset" "iso-8859-1") NIL NIL "8bit" 7 3 NIL NIL NIL NIL)("text" "html" ("charset" "iso-8859-1") NIL NIL "8bit" *3 1*NIL NIL NIL NIL) "alternative" ("boundary" "----=_20090512171853_50085") NIL NIL NIL)) A004 OK Fetch completed. 5) Request the broken message: 127.000.000.001.00143-127.000.000.001.43679: * 2 FETCH (UID 2 FLAGS (\Seen) BODYSTRUCTURE (("text" "plain" ("charset" "iso-8859-1") NIL NIL "8bit" 7 3 NIL NIL NIL NIL)("text" "html" ("charset" "iso-8859-1") NIL NIL "8bit" *1 0*NIL NIL NIL NIL) "alternative" ("boundary" "----=_20090512171902_78105") NIL NIL NIL)) A004 OK Fetch completed. >From RFC the red numbers mean: size body, number of line for the body. This makes sense, because stripping the 'control' chars from first message, size and number of lines match. But in the second message, the line number is 0 - this does not make sense. You need to test this using telnet, because outlook and thunderbird did not follow this way, they use body.peek. What do you think? Fernando

[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] Problem with IMAP (rename and delete non existent folder).

[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...

[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.

Here's the dovecot config: dovecot -n # 1.0.15: /etc/dovecot/dovecot.conf base_dir: /var/run/dovecot/ log_path: /var/log/dovecot.log log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap ssl_disable: yes login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login login_greeting: Server ready to process requests. login_process_per_connection: no max_mail_processes: 512 verbose_proctitle: yes first_valid_gid: 61 last_valid_gid: 2003 mail_privileged_group: mail mail_location: maildir:~/Maildir mail_debug: yes mail_plugins: quota autocreate imap_client_workarounds: outlook-idle delay-newmail auth default: mechanisms: plain login digest-md5 passdb: driver: pam passdb: driver: passwd passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: passwd userdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: prefetch socket: type: listen client: path: /var/run/dovecot/auth-client mode: 432 master: path: /var/run/dovecot/auth-master mode: 384 user: root group: mail plugin: quota: maildir acl: vfile:/etc/dovecot-acls trash: /etc/dovecot-trash.conf lazy_expunge: .EXPUNGED/ .DELETED/ .DELETED/.EXPUNGED/ autocreate: Trash autocreate2: Spam The setup is as follows: I've created a system user named vmail in /home with a group also called vmail. The virtual users are created in /home/vmail/username when i configure an account from thunderbird. If I send an message from a virtual user to an system user everythings is ok.

[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 30 Apr '09

30 Apr '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 30 Apr '09

30 Apr '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 22 Apr '09

22 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)
