[Dovecot] Namespaces and shared folders
by bbell2000 28 Nov '08

28 Nov '08

I had a working dovecot install before I tried to implement shared folders using namespaces. I added the following to /etc/dovecot/dovecot.conf: namespace private { separator = prefix = inbox = yes } namespace public { separator = / prefix = location = maildir:/home/public/shared/Maildir } </pre> I created my shared folder using the maildirmake command that came with qmail: maildirmake -S /home/public/shared/Maildir maildirmake -s write -f online /home/public/shared/Maildir chown -R dovecot:shared /home/public/shared find /home/public/shared -type d -exec chmod 0777 {} \; find /home/public/shared -type f -exec chmod 0666 {} \; At this point, the online folder shows up as a subscribable folder in Thunderbird. I can subscribe to online and I can still access my Inbox. But I can't get to any of the folders in my Inbox (Trash, Drafts, etc.). I can access these folders if I comment out the namespaces and revert to the default behavior. There are no clues in mail.err, mail.info or mail.warn -- the only messages are the ones written when my client establishes a successful IMAP connection. What did I do wrong? -- View this message in context: http://www.nabble.com/Namespaces-and-shared-folders-tp20727713p20727713.html Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] UIDL question
by Wouter van der Schagt 28 Nov '08

28 Nov '08

Hi all, I'm migrating a Postfix + Dovecot 1.0 server with mboxes to Qmail + Dovecot 1.4 with Maildirs and encounter the following the problem. Using perfect-maildir.pl from: http://perfectmaildir.home-dn.net/ i can relatively succesfully convert the mbox to a Maildir. The problem, however is that clients with "leave mail on server" set to on retrieve all email a 2nd time. I understand this must be because the email client "sees" a different UIDL and downloads the message again. Looking at the 1.0 configuration, i do not see a "pop3_uidl_format" setting. So was wondering how the UIDL is generated. Is anybody aware of a conversion script that properly maintains the UIDL? Or am I misisng something else here? Sincerely, - Wouter van der Schagt

Hello, I have several thousand domains on a server. I'm doing now migration to Dovecot to replace courier-authlib.

[Dovecot] Does either version 1.2 or 1.4 support UIDPLUS?
by Robert Nicholson 28 Nov '08

28 Nov '08

My ISP currently runs version 1.2 and I'm looking to make use of UIDPLUS because I want to append and then move the message I've just appended to another folder so then I need the UID in order to address the new message. My ISP says they have plans to upgrade to version 1.4 soon. Do either of these versions support UIDPLUS? ie. give me the new UID as the response to an append?

[Dovecot] expire tool question
by Jakob Curdes 27 Nov '08

Hi, I try to get expire working, with the BDB backend and mbox mailboxes. If I try to invoke the expire-tool like /usr/local/sbin/dovecot --exec-mail ext /usr/local/libexec/dovecot/expire-tool --test I get [root@m ~]# /usr/local/sbin/dovecot --exec-mail ext /usr/local/libexec/dovecot/expire-tool --test Error: read(/var/run/dovecot/dict-server) failed: Remote disconnected Hmm. I searched for hints but could not find a related discussion or problem. Here are the relavant config parts: dict { expire = db:/var/lib/dovecot/expire.db } plugin { # expire plugin expire_dict = proxy::expire expire = backup 7 spam 30 # If you have a non-default path to auth-master, set also: auth_socket_path = /var/run/dovecot/auth-master } Any ideas? Has anybody got this working ? The file /var/lib/dovecot/expire.db doas not exit even though I restarted DC quite a while ago. Regards, Jakob

In my case, the cause was a large spam message (above the configured MaxMessageSize parameter for DSPAM) that was skipped during tests and thus no signature was added. Might this be true in your case? As a general suggestion for Johannes: maybe it is better to ignore this error silently, just move the message and don't call DSPAM? > I checked that the given location for the dspam executable is correct, > that the user executing it (dovecot?) is actually able to execute dspam > and that dspam trusts this user.

I have lines like > X-DSPAM-Signature: 1,49084a24139132188715614 Another guess: if that comma is not a misprint, something is wrong in your setup. Regards Eugene

[Dovecot] Can I import RFC822 messages into Dovecot from file system
by bbell2000 27 Nov '08

27 Nov '08

I'm returning to qmail and dovecot after having suffered a complete failure with a different mail system and I'm now trying to figure out the easiest way to recover our messages from the failed system. The messages are stored as RFC822 in individual files and I can easily identify which message belongs to whom. I have qmail and dovecot configured to use Maildir format. I know I can probably write a script that resends the messages... but in addition to adding another layer of transport headers I really don't want, it's going to be way slow unless I disable my current content filters. I'm new to dovecot and what's got me hung up are the indexes that dovecot maintains in each user's directory. Otherwise, I'd probably try copying the messages into Maildir/cur just to see if it worked. I could sure use some ideas about an efficient, reliable means of getting our old messages back. Thanks. -- View this message in context: http://www.nabble.com/Can-I-import-RFC822-messages-into-Dovecot-from-file-s… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] Antispam plugin + script sieve
by Allan Cassaro 27 Nov '08

27 Nov '08

Hi guys, I will start a little script that receive via antispam plugin an email, extract the "from" and "return-path" and create alter the sieve script of the user that send the e-mail. Well, I don't speak english very well (I speak like Borat!!!), but with some examples is better to understand: 1) Some user move an "undesirable" mail to "Automatic Block" folder 2) The antispam plugin call my script 3) The script parse the e-mail and extract the from and return-path mail 4) A rule is added to ~/.dovecot.sieve to dicard messages that came from that e-mail 5) If the user remove the mail from "Automatic Block" folder, the script remove this rule So, my question is: anyone is working on something similar with this? (I don't want to reinvent the wheel) Regards. -- "Não deixe a faculdade atrapalhar seus estudos." http://allan.cassaro.googlepages.com

[Dovecot] deliver segv on sieve redirect
by Andy Howell 27 Nov '08

27 Nov '08

Hello, I've been trying out the bleeding edge, 1.2.alpha4. I'm having a problem with deliver and dovecot-1.2-sieve-0.1.1. I get a segv on this sieve script: require ["fileinto", "reject", "vacation", "envelope", "regex"]; if header :contains "subject" ["urgent"] { redirect "someone(a)somewhere.net"; fileinto "test"; } Seems its happening on the "redirect". If I put the fileinto before the redirect, the fileinto works. I tried putting extra debug statements in plugins/lda-sieve/lda-sieve-plugin.c right after the sieve_execute in lda_sieve_run, but it never prints anything. I'm guessing thats the right place. Its quite possible there is something amiss in my setup. My logs show: Nov 26 02:51:12 marvin dovecot: deliver(andy(a)x.y.org): sieve: using sieve path: /var/mail/vhosts/x.y.org/andy/.dovecot.sieve Nov 26 02:51:12 marvin dovecot: deliver(andy(a)x.y.org): sieve: opening script /var/mail/vhosts/x.y.org/andy/.dovecot.sieve Nov 26 02:51:12 marvin dovecot: deliver(andy(a)x.y.org): sieve: executing compiled script /var/mail/vhosts/x.y.org/andy/.dovecot.sieve Nov 26 02:51:12 marvin postfix/pipe[17027]: 0CA895CB3A: to=<andy(a)x.y.org>, relay=dovecot, delay=0.41, delays=0.33/0.01/0/0.07, dsn=5.3.0, status=bounced (Command died with signal 11: "/usr/libexec/dovecot/deliver") Thanks, Andy

[Dovecot] Released Sieve v0.1.2 (important bug fixed)
by Stephan Bosch 26 Nov '08

26 Nov '08

Hello Dovecot users, Today, Andy Howell tripped an important bug in the Sieve interpreter that makes it crash when redirect is executed. That is why I quickly release yet another new version to provide a fix for this bug. I really should prevent this from happening again in the future by extending the test suite to test the execution of actions. Changelog v0.1.2: - Fixed important bug in the redirect action (and probably other actions like reject and vacation that only send messages). This was a bug in the handling of context information during the execution of actions. It caused the sieve interpreter to crash with a segfault when redirect was executed. The release is available here: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.2.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.2.tar.gz.sig Refer to the initial release mail for more information: http://www.dovecot.org/list/dovecot-news/2008-October/000087.html Regards, -- Stephan Bosch stephan(a)rename-it.nl IRC: Freenode, #dovecot, S[r]us

[Dovecot] Unable to use imapflags in sieve
by Guillaume Hilt 25 Nov '08

25 Nov '08

Hello, I'm using dovecot 1.1.6 with libsieve 2.2.5 and I can't use the imapflags extension. Here's the begginning of my .dovecot.sieve file : require ["fileinto"]; #require "imapflags"; #require "reject"; #if header :contains "X-DSPAM-Probability: 0.9" { # addflag "$label3"; #} # On déplace le spam dans le dossier Spam et on s'arrête là if header :contains "X-DSPAM-Result" "Spam" { fileinto "Spam"; # addflag "\\Seen"; stop; } # Si le destinataire est l'user apache, on discarde le mail if address :is "to" "ftp(a)shadowprojects.fr" { discard; } # Listes de diffusion if header :contains "List-Id" "dovecot.dovecot.org" { fileinto "Listes.Dovecot"; stop; } If i enable imapflags (require ["fileinto","imapflags"];) sieve won't work anymore (same with reject by the way). Only enabling it without using it (with addflag) is enough to stop sieve from working. All my emails will be delivered in my inbox despite the rules I use. If I remove imapflags, everything is working fine. And I don't see anything in my logs explaining the problem.

[Dovecot] Released Sieve v0.1.1 and ManageSieve v0.11.2 for Dovecot v1.2.alpha4
by Stephan Bosch 25 Nov '08

25 Nov '08

Hello Dovecot users, Since the first release of the new Sieve implementation, not that many bugs were reported. This is probably due to the fact that it is not tried yet by that many people. In the mean time, I did find and fix some more bugs myself, I adapted to changes in Dovecot, wrote some more documentation and started work on the enotify extension. Both Sieve and ManageSieve were changed to match API changes in Dovecot and therefore older versions will not compile against the new Dovecot release. Likewise, these new Sieve and ManageSieve releases will not compile for older Dovecot versions. Changelog Sieve v0.1.1: * Re-enabled support for compiling against dovecot headers. Much like cmusieve, command line tools like sievec and sieved are not compiled in this case. * Started implementation of enotify extension. Not anywhere near finished though. * Adapted to changes in Dovecot on various occasions, making this release dependent on Dovecot >= v1.2.alpa4. + Improved logging of errors at specific occasions and added debug messages to find script execution problems quicker. + Removed code duplication between command line tools and the test suite. Also restructured the sources of the tools. + Added UTF-8 to UTF-7 folder name conversion for compatibility with IMAP. + Created man pages for the command line tools. These are automatically installed upon 'make install' + Incorporated Valgrind support into the test suite and fixed a few memory leaks in the process. - Fixed compile error surfacing for gcc3.4. Forgot mask argument for the open() system call when the O_CREAT flag is specified. Bug found by Sergey Ivanov. - Fixed bug in the sievec tool. -d output was always written to stdout. - Fixed important bug in the imap4flags extension. When no :flags argument is specified, the previous version would always use the final value of the internal variable to set the flags. This means that modifications to the internal variable also affected the bare fileinto/keep actions executed earlier. This does not comply to the RFC. - Fixed bug in the include extension's import/export commands. Duplicate import/exports caused problems. - Fixed bug in the handling of non-existent scripts. Errors were sometimes ignored. - Dovecot omitted unfolding multi-line headers. This was added to the cmusieve plugin after the code was incorporated into the new implementation. This is now implicitly fixed by concurrent change in Dovecot. Changelog ManageSieve v0.11.2: * Adapted to changes in Dovecot, making this release dependent on Dovecot >= v1.2.alpa4 The following files are released: Sieve: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.1.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.1.tar.gz.sig ManageSieve package: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.2.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.2.tar.gz.s… ManageSieve patch: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.alpha4-managesieve-0.11.2.d… http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.alpha4-managesieve-0.11.2.d… The full story of the new Sieve implementation is available in my previous posting: http://www.dovecot.org/list/dovecot-news/2008-October/000087.html I still need to update the wiki with pointers to the new Sieve implementation. I hope to have some time and motivation to do so in the next few days. Have fun testing the new releases and don't hesitate to notify me when there are problems.

[Dovecot] v1.1.7 released
by Timo Sirainen 25 Nov '08

25 Nov '08

http://dovecot.org/releases/1.1/dovecot-1.1.7.tar.gz http://dovecot.org/releases/1.1/dovecot-1.1.7.tar.gz.sig I should have released this earlier since v1.1.6 had that annoying startup problem, but surprisingly few people complained about it so I kind of forgot about it then. BTW. v1.2 progresses nicely. Now that shared mailboxes are finally fully supported, there aren't any widely used IMAP features missing from Dovecot. v1.2.beta1 shouldn't be in too distant future anymore. * IMAP QUOTA extension now returns "MESSAGE" quota, not "MESSAGES". This makes Dovecot now RFC 2087 compliant. Hopefully this change doesn't break anyone's Dovecot-specific quota checking code.. + Added !include and !include_try directives to config file reader. Note that !include doesn't currently work with deliver. The main point here is that ssl_key_password can be placed to a different file with !include_try that deliver can just ignore. + More error/debug message logging improvements. - v1.1.6 gave "userdb didn't return a home directory" error at startup - Some config file parsers (deliver, passwd-file, acl, trash) ignored the file's last line if it didn't end with LF. - fts: SEARCH SUBJECT didn't search messages that weren't already in fts index. - fts-solr: Don't assert-crash if we couldn't connect to Solr. - IMAP: Mailbox deletion gave an error, but still worked, if mails' control directory wasn't the same as index directory. - Several fixes to rarely used mailbox list layout configurations.

[Dovecot] PLAIN password scheme question
by Dmitri V. Ivanov 24 Nov '08

24 Nov '08

Hi, ppls There is some problem with using passwd-like file and plaintext passwords within it. Let's assume we have users speaking russian. They think and remember their passwords also within russian words (they just not change keyboard layout before entering their passwords). So if the user has password like ":jgf" (meaning "ass" in russian) and passwords are stored into passwd-like file within {PLAIN} scheme what will happen? ===== user:{PLAIN}:jgf:1234:1234:.... ===== Isn't it a reason to implement something like {HEX} and why?

The logs stating the "File too large" errors belong to dovecot's deliver process. While I was searching for a solution, I read that deliver honors mailbox_size_limit setting of postfix, I'm not sure if that is correct or not. Note that the destination mailboxes are smaller than 2GB here, but still gets "File too large" error. The machine is 64-bit, so no fs related kernel limits on file size. I have not dived into postfix and/or dovecot internals, but my guess is , dovecot gets the mailbox size limit and behaves accordingly. If that is the case, the problem can be fixed in dovecot's deliver code. If postfix sets file size limit with ulimit before execing deliver, OR uses a similar process which is out of deliver's control, then there is nothing concerning dovecot. If someone can clarify the issue I would be happy. -- Gokdeniz Karadag

[Dovecot] pam auth fail considered mail.error?
by David Halik 24 Nov '08

24 Nov '08

Hello all, Following the Dovecot wiki and migration help, we recently migrated our core IMAP systems from Courier to Dovecot on Solaris. So far it's been working great, but I have one issue that I'm curious about. Just as the docs mention, we also use "syslog_facility = mail" for logging. Unlike in the past, failed PAM auth attempts are now getting logged as mail.error: Nov 24 08:34:34 xxx.xxx.xxx.xxx dovecot: [ID 107833 mail.error] auth-worker(default): pam(dhalik,xxx.xxx.xxx.xxx): pam_authenticate() failed: Authentication failed Is there a reason for this, or a way to configure this behavior? mail.error is a little harsh for pam auth failures and I would think that the auth channel would be used instead similar to other processes (sshd, courier, etc) I'd like to continue using the mail facility, but if every time there is an auth error Dovecot reports to mail.error, my consoles and legitimate error logs are going to be full of something considered a non-issue by most. Any help is appreciated, thanks. -Dave -- ================================ David Halik System Administrator OIT-CSS Rutgers University dhalik(a)jla.rutgers.edu ================================

[Dovecot] two dovecot server using the same file system
by Osvaldo Alvarez Pozo 24 Nov '08

24 Nov '08

Hi all. I want to use two servers with dovecot using a common file system with drbd. So I have several questions. If one server write a mail to th file system he will use his name as part of the mail identification. the second server will use his own name. Each server will generate it own mail numbers . When an imap or pop user will consult the mails i shoul be confusion. Am I correct. is there a way of solving this issue?? Thanks

I manually deleted all the dovecot.index* files and the account started working. Perhaps dovecot could try the fix but if it still fails just go and delete the indexes itself?

Hi, Setting mailbox_size_limit to 0 made deliveries possible. a limit of 2000000000 (<2GB) also did not show the errors. Thank you ! :) My issue is fixed but deliver might have a bug, so I will explain things, sorry for not being clear previously. Old mail server was 32 bit(an old version of debian) and used procmail for deliveries, that setup worked with the given limit of 5GB and mailbox sizes above 1GB. After migrating to an 64 bit server (debian etch) and dovecot's deliver, the stated delivery errors appeared for mailboxes above 1 GB. As I stated at the beginning of my reply, setting mailbox_size_limit below 2GB made deliveries possible. I tried with edge values, mailbox_size_limit=2147483648 (exactly 2GB) would give the following error in postfix logs: fatal: main.cf configuration error: mailbox_size_limit is smaller than message_size_limit A limit of 2147483648 - 1 worked fine. There are two distinct bugs probably, one in postfix and one in dovecot. I guess this is result of using integer values for size limit. values greater than 2GB would wrap and cause warnings in postfix. Probably, my previous limit of 5GB would confuse things and no error was reported. (I don't know how, 5GB cannot be stored in an unsigned int, double overrun makes it within limit ? :) ) Maybe moving to "long long int" for mailbox file size is a possible solution. -- Gokdeniz Karadag

[Dovecot] OT: Run Sieve On A Mailbox Manually
by Neil 22 Nov '08

22 Nov '08

(Apologies for being offtopic.) The subject basically says it all...does anyone know of a tool to run a sieve script on a mailbox (in particular, Maildirs) manually? Ideally, I'd like to do it without adding a bunch of new headers to the mail. So, could I just do a find (or for-loop, if it was just one maildir) command and pipe all the mails into deliver..? Thanks, Neil.

[Dovecot] expire-tool fails if mail_location contains %h
by Thorsten Vollmer 21 Nov '08

21 Nov '08

Hi Timo, not long ago you fixed a bug regarding the expansion of ~/ in mail_location that prevented expire-tool from working correctly. A similar problem exists if mail_location contains %h: expire-tool will use the wrong path to access the mailbox. After replacing %h with ~, expire-tool works as expected. Why are there two variables for the home directory? Maybe the use of %h could be discouraged, sparing you some problems. Regards, Thorsten

[Dovecot] Separate quotas not displayed correctly
by Laurent Blume 21 Nov '08

21 Nov '08

Hello all, My system is set up to have quotas both on /var/mail, where emails are received, and on /export/home, where users' homedirs are. But the client (Thunderbird) shows the same /export/home values both for the Inbox and for the folders in the homedir, so a user cannot know where she stands on her /var/mail use. This is Dovecot 1.1.5. As per the wiki, the dovecot.conf file contains this: quota = fs:INBOX:mount=/var/mail quota2 = fs:Others:mount=/export/home A sample user: # quota -v testimap Disk quotas for testimap (uid 1143): Filesystem usage quota limit timeleft files quota limit timeleft /export/home 6490 10000 15000 0 0 0 /var/mail 0 20000 25000 0 0 0 When Icheck the Quota tab in the Properties of the Inbox, the field contains "Others", and the value are 6490 out of 10000. Any idea why this doesn't display the value of /var/mail?

[Dovecot] Dovecot and Bogofilter
by Matthias-Christian Ott 21 Nov '08

21 Nov '08

Hi, on my small Xen-virtualised server with 48 MiB RAM I use Postfix and Dovecot, because the Debian administrators dislike qmail [1], which is in my opinion despite some maintainability and code quality issues a quite well designed software, because it mostly follows the UNIX principles. Postfix is not able to sort my E-Mail into different Maildir folders and after I looked at procmail's source code, I decided to use Dovecot's LDA, because it supports sieve via a plugin. All in all it worked after some tweaking and Dovecot is now responsible for authentication and delivery. Furthermore I want to setup a spam filter and due to the memory constraints I decided in favour of bogofilter (I made no real world tests, but the authors claim that it's fast and has a small memory footprint). My first idea was train bogofilter via a cronjob that runs bogofilter for each E-Mail in my spam folder and deletes them afterwards. Then I stumbled upon the dovecot antispam [2] plugin and quickly wrote a backend for bogofilter. During the development I realised that bogofilter has to update the X-Bogosity header of the reclassified E-Mails. Johannes Berg told me that he wasn't sure whether dovecot would be able to do this and recommended to ask this on the mailing list. An other problem is that each mail needs to be initially classified and due to the fact that sieve is not able to execute external programmes, deliver has to do this task. I'm currently thinking of possibilities to implement this, so far I came up with the following: 1. Write a generic pipe plugin which can execute an arbitrary number of programmes. The problem with this is that I'm not sure how to integrate this is in Dovecot's configuration file. I thought of something like this: pipe = prg1 | prg2 2. Write a bogofilter-specific plugin for this. Anyhow I would like to take this opportunity to criticise Dovecot for being a bloated (unnecessary abstractions, verbose, pseudo object-oriented, ...), non-suckless [3] and non-unixish (plugin architecture, monolithic design, ...) software which in return works quite well and stable so far. I appreciate any suggestions, ideas or criticism. I would really like to finish configuring my mail server as soon as possible.

[Dovecot] nfs_flush_fcntl failed: No locks available

[Dovecot] Per User Quotas
by Peter Fraser 21 Nov '08

21 Nov '08

HI All Asking for a little patience and a bit of help here. I'm using dovecot-1.1.3_1 with postfix and squirrelmail. I have implemented a global quota successfully. That works fine. I want to now implement per user quotas. So far I have read the howto in the documentation and searched several threads but can't seem to get it working properly. My LDAP server is Windows 2003 Active Directory. Is there any documentation specific to AD that I could look at or any other doc that could help me? My last effort was to put this in dovecot-ldap.conf user_attrs = streetAddress=quota_rule4=*:storage=%$M ,=uid=1002,=gid=1002,=home=/home/vmail/%u and this in dovecot.conf in addition to the other quota rules. quota_rule4 = *:bytes=%$ I then put the quota in the streetAddress area of AD. I'd certainly appreciate any help. Thanks.

[Dovecot] make archive emails undeletable?
by Rob Nichols 21 Nov '08

21 Nov '08

I've been using dovecot for a year or two now, and really like it. I have a fairly simple setup, but I think it's time to get a little more advanced. I keep an "archive" of all my email, both sent and received. Every once in a while I get confused, and accidentally delete something from my archive. I also worry that I'll misconfigure a mail client some day and accidentally wipe out my "trash" folder. I would like some way to prevent deletion in several mailboxes. Is that possible? It looks like ACL could do this, but I can't quite figure out where to start. Any pointers would be greatly appreciated. Thanks, Rob

[Dovecot] sieve-body extension support for deliver LDA's sieve plugin
by BrunoM 21 Nov '08

21 Nov '08

Hello, I just read your message about sieve and body-extension in Dovecot. Do you have news on that topic? I just have to filter mails containing a particular text fragment, and I cannot do without sieve body, I think.. Thank you for any clue you'd be able to give me ! Regards, Bruno --- Hi Timo & Co, Is there any time frame for updating the deliver LDA's sieve plugin code to that from Cyrus IMAPd v2.3.x? I ask as I'm looking for the functionality of the sieve-body extension, as described here: http://www.ietf.org/internet-drafts/draft-ietf-sieve-body-06.txt This requirement has come up as we're upgrading from a Courier-IMAP/maildrop configuration that has some filtering based on message body content. As an aside, if that time frame is undefined or will be long, if I use maildrop instead as my LDA, will I loose the instant delivery notification via IMAP IDLE? Thanks very much, Scott

[Dovecot] %d in deliver
by Mark Zealey 21 Nov '08

21 Nov '08

Hi there, I run a system that has a lot of virtual users. We invoke deliver from exim and pass the directory to deliver into using the HOME environment variable, so deliver doesn't do any database lookups during the delivery process. The exim pipe environment is described at http://exim.org/exim-html-current/doc/html/spec_html/index.html#toc0239, but basically I'd like to know the domain as well as the user, however deliver doesn't seem to pick this up. Is there any way that you could extend deliver to make it either pick up the domain (or correct username) from the command line, but not do an authdb lookup; or get it to read the domain from an environment variable (or be able to print the contents of an arbitrary environment variable in a formatted string)?

[Dovecot] namespace public / namespace shared - question
by Michal Soltys 21 Nov '08

21 Nov '08

After looking through wiki/config/list I'm still not sure, what exactly is the difference between those two. Even all the examples in dovecot's wiki don't have a single "namespace shared" anywhere. And there's only short mention about the difference in dovecot.conf . Peeking into rfc2342 - would shared namespace relate to "Other Users' Namespace(s)" and public namespace to "Shared Namespace(s)" ? Does perhaps the difference only lie on the client side, depending on the namespace it's asking, while functionally it's the same from the perspective of dovecot ?

I use LDAP for the user database and Dovecot LDA. --- dovecot.conf mail_location = maildir:/var/spool/mail/data/%Lu:INDEX=/var/spool/mail/index/%Lu auth default { mechanisms = plain (Note: TLS is used anyways..) userdb prefetch { } passdb ldap { # Path for LDAP configuration file, see doc/dovecot-ldap-example.conf args = /etc/dovecot/dovecot-ldap.conf_passdb (symlink do dovecot-ldap.conf) } userdb ldap { # Path for LDAP configuration file, see doc/dovecot-ldap-example.conf args = /etc/dovecot/dovecot-ldap.conf_userdb (symlink do dovecot-ldap.conf) } socket listen { master { path = /var/run/dovecot/auth-master mode = 0600 user = maildeliver group = mail } } } --- dovecot-ldap.conf Q1: auth_bind_userdn (commented since it would avoid the use of passdb and userdb, right?) # auth_bind_userdn = ... # userdb user_filter = (&(objectclass=postfixuser)(mail=%u)) user_attrs = uid=user # passdb pass_filter = (&(objectclass=inetlocalmailrecipient)(uid=%u)) pass_attrs = uid=user,userPassword=password,uid=userdb_user --- mail log host postfix/smtpd[8923]: connect from localhost[127.0.0.1] host postfix/smtpd[8923]: 5B449EA2C6: client=localhost[127.0.0.1] host postfix/cleanup[8925]: 5B449EA2C6: message-id=<20081121103114.5B449EA2C6@host> host postfix/smtpd[8923]: disconnect from localhost[127.0.0.1] host postfix/qmgr[8894]: 5B449EA2C6: from=<sender(a)otherdomain.org>, size=368, nrcpt=1 (queue active) host deliver(person(a)mydomain.com): Loading modules from directory: /usr/lib/dovecot/modules/lda host deliver(person(a)mydomain.com): Module loaded: /usr/lib/dovecot/modules/lda/lib10_quota_plugin.so host dovecot: auth(default): master in: USER 1 person(a)mydomain.com service=deliver host dovecot: auth(default): prefetch(person(a)mydomain.com): passdb didn't return userdb entries (#0) host dovecot: auth(default): ldap(person(a)mydomain.com): user search: base=dc=mydomain,dc=com scope=subtree filter=(&(objectclass=postfixuser)(mail=person(a)mydomain.com)) fields=uid host deliver(person(a)mydomain.com): auth input: person(a)mydomain.com (#1) host deliver(person(a)mydomain.com): auth input: user=person~mydomain.com host deliver(person(a)mydomain.com): auth input: uid=501 host deliver(person(a)mydomain.com): auth input: gid=12 (#2) host deliver(person(a)mydomain.com): maildir: data=/var/spool/mail/data/person@mydomain.com:INDEX=/var/spool/mail/index/person@mydomain.com (#3) host deliver(person(a)mydomain.com): maildir: root=/var/spool/mail/data/person(a)mydomain.com, index=/var/spool/mail/index/person(a)mydomain.com, control=, inbox= host dovecot: auth(default): master out: USER 1 person(a)mydomain.com user=person~mydomain.com uid=501 gid=12 host deliver(person(a)mydomain.com): msgid=<20081121103114.5B449EA2C6@host>: saved mail to INBOX host postfix/pipe[8929]: 5B449EA2C6: to=<person(a)mydomain.com>, relay=dovecot, delay=0.69, delays=0.19/0.02/0/0.48, dsn=2.0.0, status=sent (delivered via dovecot service) host postfix/qmgr[8894]: 5B449EA2C6: removed What I don't get is that since I use userdb (read mail log lines marked (#0-3) and the "mail_location" option from dovecot.conf), mail should be saved to "person~mydomain.com" and not "person(a)mydomain.com" on the disk(?). Q2: Did I misunderstood the meaning of userdb/mail_location, is that right (this behavior)? Q3: Is it misconfigured? I want to save mail on the disk to person~mydomain.com, when I get that right (save mail to what line #1 tells is "user"), I'll use mailRoutingAddress (my mailroutingaddress = person~mydomain.com(a)mydomain.com, mail_location would use %Ln). The passdb and userdb prefetch are working ok on the user is checking mail. thanks = PathMaker for Six Sigma Complete low-cost Six Sigma toolset.

[Dovecot] CRAM-MD5 and proxy_maybe
by David Jonas 20 Nov '08

20 Nov '08

When using proxy_maybe CRAM-MD5 authentication fails when the connection is proxied. Is this expected behavior? Is proxy_maybe too simplified for this case? We're using SQL so I could rewrite the query with IFs to fake proxy_maybe and return the password as NULL and nologin as Y, but if it works that way couldn't it work with proxy_maybe? This works: password_query = \ SELECT NULL AS password, host, CONCAT(user,'@',domain) AS destuser \ 'Y' AS nologin, 'Y' AS nodelay, 'Y' AS proxy \ FROM accounts WHERE class='pop' AND domain='%d' This doesn't work if proxied and CRAM-MD5 auth: password_query = \ SELECT \ CONCAT(user,'@',domain) AS user, password, \ host, 'Y' AS proxy_maybe, \ target AS userdb_home, uid AS userdb_uid, gid AS userdb_gid \ FROM accounts WHERE \ class='pop' AND domain='%d' AND user='%n' \ LIMIT 1 Thanks, David

[Dovecot] Sieve RFC5229 support?
by list_dovecot＠bluerosetech.com 20 Nov '08

20 Nov '08

I'd like to take advantage of RFC5229 match variables (it would reduce the number of rules I have by an order of magnitude); however, the required extension isn't supported yet. Am I mistaken? If not, are there plans to support it?

[Dovecot] Unbreakable NFS locking issues...
by Rod Treweek 20 Nov '08

20 Nov '08

Hello All, We are struggling to find a solution to a problem we are encountering with a load-balanced email setup. Currently, we have a Coyote loadbalancer, and 3 Postfix/Dovecot nodes that then get their information from a mysql database. The problem is that after a couple weeks, we start seeing NFS locking issues occur, which then takes email completely down, requiring a site visit to basically do an interactive mode reboot to shut off NFS so that we can remount the filesystem again. We have our mailstore on an Aberdeen NAS which is accessed over NFS v. 4. Dovecot version 1.1.2 Here's the relevant mysql string: grep -v '^ *$#.*$\?$' dovecot-mysql.conf driver = mysql connect = host=X.X.X.X dbname=Something user=Something password=Something password_query = SELECT username as user, password, concat('/NFS1MAILDIR/mailSysV2/', maildir) as userdb_home, concat('maildir:/NFS1MAILDIR/mailSysV2/', maildir) as userdb_mail, 143 as userdb_uid, 143 as userdb_gid, concat('*:bytes=', floor(quota*1024)) AS quota_rule FROM mailbox WHERE username = '%u' AND active = '1' user_query = SELECT concat('/NFS1MAILDIR/mailSysV2/', maildir) as home, concat('maildir:/NFS1MAILDIR/mailSysV2/', maildir) as mail, concat('maildir:/NFS1MAILDIR/mailSysV2/', maildir) as maildir, 143 AS uid, 143 AS gid, concat('*:bytes=', floor(quota*1024)) AS quota_rule FROM mailbox WHERE username = '%u' AND active = '1' And here's what our configuration is on each of the nodes: dovecot -n # 1.1.2: /usr/local/etc/dovecot.conf protocols: imap pop3 ssl_ca_file: /usr/local/etc/dovecot/certs/tdpserver.crt ssl_cert_file: /usr/local/etc/dovecot/certs/tdpserver.crt ssl_key_file: /usr/local/etc/dovecot/certs/tdpserver.key ssl_parameters_regenerate: 0 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 login_user: postfix login_greeting: Something witty here.. login_process_per_connection: no login_max_connections: 512 max_mail_processes: 2048 mail_max_userip_connections: 50 verbose_proctitle: yes first_valid_uid: 69 last_valid_uid: 500 first_valid_gid: 69 last_valid_gid: 500 mail_access_groups: postfix mail_privileged_group: postfix mail_location: mbox:/NFS1MAILDIR/mailSysV2/%d/%u:INDEX=/usr/local/mail/indexes/%d/%1n/%n mmap_disable: yes dotlock_use_excl: no mail_nfs_storage: yes mail_nfs_index: yes 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_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota 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 netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(imap): delay-newmail netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(pop3): pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: mechanisms: login plain user: dovecot passdb: driver: sql args: /usr/local/etc/dovecot-mysql.conf userdb: driver: sql args: /usr/local/etc/dovecot-mysql.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: dovecot group: dovecot plugin: quota: dict:user::proxy::quota imap_quota: dict:user::proxy::quota quota_rule: *:storage=528576 dict: quota: mysql:/usr/local/etc/dovecot/dovecot-dict-quota.conf Any help you can offer is greatly, greatly appreciated, as well as opinions on any other 'validated' postfix/dovecot email enterprise design solutions.

[Dovecot] New message notification
by Juan Asensio Sánchez 19 Nov '08

19 Nov '08

Hi What is the best option to notify a user that a message has arrived? The intention is to write a script that connects to a jabber server and checks if the user is online, so then a message is sent to user notifying him that he has received a new message. The solution should be compatible with Sieve filtering, so the script should not be executed when the message is moved to the SPAM folder, or pass to the script an argument specifying the folder where the message has been saved. Regards and thanks in advance. Juan Asensio Sánchez - http://www.nutum.es
