[Dovecot] Wrong size calculating with maildirquota
by Umut Arus 22 Sep '07

22 Sep '07

Hello, I'm using dovecot-1.0.5 with postfix. There is a problem which dovecot folder's size calculating wrong. It doesn't calculates whole folders' sum. Only maildirsize file keeps the first requested folder's size (in this example, Inbox). The example shows Inbox's size, another folder's size didn't add although connecting with IMAP. As the effect, I can not manage users' quota. Is there any hint with using namespace. Include quota size infos in control file, [root@xxxx Maildir]# cat /var/no-quotas/control/oneusername/maildirsize 512000000S 4941014 190 1849 1 40788 1 Also, namespace descriptions in dovecot.conf, namespace private { separator = / prefix = inbox = yes location = maildir:~/Maildir:INDEX=/var/no-quotas/index/%u:CONTROL=/var/no-quotas/control/%u } namespace private { separator = / prefix = mail/ #hidden = yes location = maildir:~/Maildir/.mail:INDEX=/var/no-quotas/index/%u:CONTROL=/var/no-quotas/control/%u } thanks in advance.

[Dovecot] Deliver parameter problem
by Umut Arus 22 Sep '07

22 Sep '07

Hello, I'm using dovecot-1.0.5 with postfix. I have to use deliver from procmail because I have some filters. There is no document about how to using deliver parameters (-d) other than http://wiki.dovecot.org/LDA . If I set -d parameters manually as a username everything is ok. I can not set users' mail quota (don't lookup) with mysql db if I haven't set -d parameter as receipt username in procmail. How can I describe user (-d) parameter's variable in procmail? Procmail configuration, :0 | /usr/local/dovecot/libexec/dovecot/deliver -f $blabla -d $blabla2 Output of the configuration, # 1.0.5: /usr/local/dovecot/etc/dovecot.conf protocols: imap imaps pop3 pop3s listen: 10.1.1.168 ssl_cert_file: /usr/local/dovecot/etc/dovecot.cert.pem ssl_key_file: /usr/local/dovecot/etc/dovecot.key.pem disable_plaintext_auth: no login_dir: /usr/local/dovecot/var/run/dovecot/login login_executable(default): /usr/local/dovecot/libexec/dovecot/imap-login login_executable(imap): /usr/local/dovecot/libexec/dovecot/imap-login login_executable(pop3): /usr/local/dovecot/libexec/dovecot/pop3-login mail_location: maildir:%h/Maildir:INDEX=/var/no-quotas/index/%u:CONTROL=/var/no-quotas/control/%u mail_debug: yes mail_full_filesystem_access: yes mail_executable(default): /usr/local/dovecot/libexec/dovecot/imap mail_executable(imap): /usr/local/dovecot/libexec/dovecot/imap mail_executable(pop3): /usr/local/dovecot/libexec/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): mail_plugin_dir(default): /usr/local/dovecot/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/dovecot/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/dovecot/lib/dovecot/pop3 pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xv%08Xu namespace: type: private separator: / location: maildir:~/Maildir:INDEX=/var/no-quotas/index/%u:CONTROL=/var/no-quotas/control/%u inbox: yes namespace: type: private separator: / prefix: mail/ location: maildir:~/Maildir/.mail:INDEX=/var/no-quotas/index/%u:CONTROL=/var/no-quotas/control/%u auth default: verbose: yes debug: yes passdb: driver: pam userdb: driver: sql args: /usr/local/dovecot/etc/dovecot-sql.conf userdb: driver: prefetch socket: type: listen master: path: /var/run/dovecot/auth-master mode: 438 plugin: quota: maildir:storage=500000:ignore=trash regards,

[Dovecot] Assertion failure in mail-index-view-sync.c
by Doug Council 22 Sep '07

22 Sep '07

I have been getting these assertion failures every couple days, killing the IMAP process. After it happens, I can login immediately and everything is fine until it happens again. Here is the log entry: Sep 10 10:03:41 mailbox-4 dovecot: nh: IMAP(username): file mail-index-view-sync.c: line 666 (mail_index_view_sync_end): assertion failed: (view->log_file_offset >= view->map->hdr.log_file_int_offset) Sep 10 10:03:41 mailbox-4 dovecot: child 38458 (imap) killed with signal 6 It started after I disabled indexing for deliver and IMAP: mail_location = maildir:~/Maildir:INDEX=MEMORY I removed the dovecot.index* files from all of the maildir directories (including the root/INBOX), but that didn't help. I have upgraded to 1.0.5, but that didn't help either. Any ideas as to what might be causing this? Thanks, -Doug

Hi. I am testing E-mail delivery by using dovecot 1.1 alpha6. But, The following message(syslog) is output while receiving mail. And, I'm try to looked for this reason in that source code. Hum... I think why the deliver is not using a 'MAILBOX_TRANSACTION_FLAG_ASSIGN_UIDS' flag. # deliver/deliver.c:142::deliver_save() function - calling mailbox_transactio n_begin() The imap's COPY/APPEND commands is using this flag.

[Dovecot] dovecot 1.1alpha6 deliver+quota bugs
by Andrew Garner 22 Sep '07

22 Sep '07

I was playing around with dovecot-1.1 and maildir++ quotas, and ran into a reproducible error with indexing. This only seems to be a problem for new maildirs. If I send a message without the quota plugin on, and "seed" the index/control files, future deliveries with the quota plugin seem to succeed without errors.

[Dovecot] quota reporting and mail.app
by Mike Horwath 20 Sep '07

20 Sep '07

Hi everyone. I can't get mail.app to report back correct quota information using mail.app and dovecot (though it works with courier-imap). I am looking at migrating away from courier-imap to dovecot but this issue is something I need to have resolved <somehow>. Thunderbird is fine and reports back good info on either connection. I am off to read RFCs (can't I just read the sendmail book again? Might be easier...) to see what should really be done.

[Dovecot] SASL from remote server
by Daniel L. Miller 20 Sep '07

20 Sep '07

Is there a way, using Dovecot and Postfix, to use SASL from a remote server? Since it appears the communication uses Unix sockets, does this mean it is restricted to local services only? I have a two-server configuration, where my firewall also runs the mail gateway/filter (Postfix + ASSP). My internal server has Postfix + Dovecot. Right now I have my internal server configured to use Dovecot SASL, but the external server is still using the Courier authdaemon against the LDAP database. -- Daniel

[Dovecot] Running a script when a mail arrives
by Dennis Becker 20 Sep '07

20 Sep '07

Hi, I'm trying to execute a script when a mail arrives in a given user's mailbox. Something like .dovecot.sieve. The reason I'm not using sieve itself is that I need to do stuff on mail arrival, which is beyond sieve's features. So is there a way to tell dovecot to run a script when a mail arrives in a certain mailbox? Optionally a solution to forward the whole mail to a script would be good too. -- Dennis Becker

[Dovecot] Multiple Quota "ignore=" in Dovecot 1.0.x?

Any chance that multiple "ignore=" statements cab be specified for a quota in Dovecot 1.0.x? We know this is possible in 1.1, but won't be able to update until it's stable. We've tried: quota = maildir:storage=256000:ignore=Junk:ignore=Trash and quota = maildir:storage=256000:ignore=Junk,Trash However, only "Junk" is ignored, and email can't be deleted when the mailbox is full. Thanks! Rich

Hello, hope guys someone can help me i have installed mailserver according this tutorial http://johnny.chadda.se/2007/04/15/mail-server-howto-postfix-and-dovecot-wi… which is linked from dovecot maunal pages Using Debian Etch 4.1 amd64, Postfix 2.3.8, Dovecot v1.0.rc15 , have tried also 32bit version with same result Everything works great except when i send mail to non-existing user in existing domain Dovecot is ignoring Postfix main.cf values delay_warning_time = 4h and unknown_local_recipient_reject_code = 550 And is sending error message ca every two hours for 4 days like : Out: 220 mailserver2.mydomain.tld ESMTP Postfix (Debian/GNU) In: EHLO mail.otherdomain.tld Out: 250- mailserver2.mydomain.tld Out: 250-PIPELINING Out: 250-SIZE 10240000 Out: 250-VRFY Out: 250-ETRN Out: 250-STARTTLS Out: 250-AUTH PLAIN Out: 250-AUTH=PLAIN Out: 250-ENHANCEDSTATUSCODES Out: 250-8BITMIME Out: 250 DSN In: STARTTLS Out: 220 2.0.0 Ready to start TLS In: EHLO mail.otherdomain.tld Out: 250- mailserver2.mydomain.tld Out: 250-PIPELINING Out: 250-SIZE 10240000 Out: 250-VRFY Out: 250-ETRN Out: 250-AUTH PLAIN Out: 250-AUTH=PLAIN Out: 250-ENHANCEDSTATUSCODES Out: 250-8BITMIME Out: 250 DSN In: MAIL From:<rh(a)tvujweb.cz> SIZE=704 Out: 250 2.1.0 Ok In: RCPT To:<non_existing_user(a)existingdomain.net> Out: 451 4.3.0 <non_existing_user(a)existingdomain.net>: Temporary lookup failure In: QUIT Out: 221 2.0.0 Bye I have googled out somewhere parameter for dovecot.conf unknown_address_reject_code = 550 , but Dovecot is not taking this one. Is Dovecot using Postfix paramteres delay_warning_time = and unknown_local_recipient_reject_code = ?? Assuming not, becauase Postfix is delivering over Dovecot, as defined in postfix/master.conf dovecot unix - n n - - pipe flags=DRhu user=vmail:mail argv=/usr/lib/dovecot/deliver -d $(recipient) So how can i set this two parameters ?? Thanks in advance for any hint Radim -- Radim Hejc

[Dovecot] documentation for developers
by Boris Lorbeer 20 Sep '07

20 Sep '07

Hi there, I have two questions: - Is there a dovecot documentation for developers (apart from the source itself)? - In the site I am concerned with, it happens very often that one mail is delivered to hundreds of recipients. Since almost all of the mailboxes are situated on the same filesystem, the mail is delivered by just saving it once and establishing hardlinks from the mail directories of all the other recipients to this one mail. My question now is: can dovecot's lda "deliver" be configured to deliver mail to more than one recipients and to use the hardlink method just described? Boris -- Dipl. Phys.

[Dovecot] 'r' flag in ACL stomping on 'l' flag effect
by Phil Edwards 19 Sep '07

19 Sep '07

We're using Dovecot 1.0.3, and I'm setting up some shared IMAP folders. The eventual goal is to do the standard "learn as spam" / "learn as ham" type of setup, with some cron jobs to do the message extractions. But there's one minor twist: the "learn as ham" folder will need to be write-only for users. (I'll either create a fake user with read access to extract the mail for sa-learn, or do some local filesystem access, etc. A problem for a future day.) The issue is that some of the mail being misclassified might contain sensitive information. So users should be able to copy messages into that folder, but not list or read other messages. (Yes, they will be removed from the folder by the future sa-learn script, don't worry.) I can get normal operation with the ACL plugin and a global ACL file: # "TestTwo" mailbox acl file: authenticated lrwik * OK Dovecot ready. 1 login ........ 1 OK Logged in. 2 list "" * * LIST (\Noselect \HasChildren) "." "Testing/" * LIST (\HasNoChildren) "." "Testing/TestTwo" * LIST (\HasNoChildren) "." "Testing/TestOne" 2 OK List completed. 3 select "Testing/TestTwo" * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 0 EXISTS * 0 RECENT * OK [UIDVALIDITY 1189458953] UIDs valid * OK [UIDNEXT 1] Predicted next UID 3 OK [READ-WRITE] Select completed. Now, I change the TestTwo acl file to read authenticated lwik but can no longer subscribe to the folder: 1 login ........ 1 OK Logged in. 2 list "" * * LIST (\Noselect \HasChildren) "." "Testing/" * LIST (\HasNoChildren) "." "Testing/TestTwo" * LIST (\HasNoChildren) "." "Testing/TestOne" 2 OK List completed. 3 subscribe "Testing/TestTwo" 3 NO Permission denied According to http://wiki.dovecot.org/ACL, the 'l' flag means "Mailbox is visible in mailbox list. Mailbox can be subscribed to." but the second part of that statement is not actually happening. Is this a misunderstanding on my part, or a bug? -- Phil Edwards

[Dovecot] Delete mails in dovecot POP3 has a bug/feature
by Nuilte Infotech 19 Sep '07

19 Sep '07

When a mailbox has abt 40 mails with 4-5 mb attachments , it is quite common for the pop3 connection to get timed out or disconnected esp. if user has dialup modem. In this case , dovecot seems to REALLY HIT the user hard. Because it simply DOES NOT delete mails , even if user requested so. It only deletes the mails if users succesfully logs out. No other pop3 server has this problem so i would request this bugs is fixed ASAP. Effect of this bug - user has to retry multiple times and download multiple copies of mail before it finally deleted. Server Using ubuntu 7.04 Feisty Fawn + standard apt-get dovecot. Client end tested using getmail+BrokenUIDLPOP3Retriever To be Fixed - dovecot should delete mail even if the client connection gets "broken" or disconnects "ungracefully". e.g. user hits CTRL+C with getmail.

[Dovecot] What's the best way to authenticate against Active Directory?
by Chris Johnson 19 Sep '07

19 Sep '07

Hi all, I'm working on a replacement for a legacy linux mail server: courier POP/IMAP, Postfix, OpenLDAP. One of the requirements of the new mail server is to authenticate against our AD infrastructure (I'll still keep a userdb in OpenLDAP). SSO is not required since most of the clients don't log into our domain. The current system has about 1,000 concurrent users on it during the day (almost all are IMAP users). Inbox size varies but is generally very high 1GB+. I'm considering dovecot as a replacement for courier IMAP on the new server mainly for performance reasons. Cyrus was also considered but I'd rather work with maildir format inboxes. I'm in the process of installing a "proof of concept" server with CentOS 5 and dovecot-1.0-1.2.rc15.el5. the production system will most likely run on RHEL Question: What's the best way (most reliable/fastest) to authenticate dovecot to AD? If someone is doing this in a production environment can you offer any hints on configuration for performance or what to expect in general? Thanks, chrisj

[Dovecot] Dovecot 1.0.3: mbox problems for newly created users
by Bernd Kuhls 18 Sep '07

18 Sep '07

Hi, I am having problems with Dovecot 1.0.3 and Thunderbird 2.0.0.6 when using a new user account without any mbox files present. Directory /home/$user/.imap_mail/ does not exist when Thunderbird first tries to login using IMAP to the account. On login this directory is created with a zero byte Trash file and .subscriptions containing string "Trash", so far, so good. Now I create a new message in Thunderbird and save it as draft. A zero byte file "Drafts" is created in /home/$user/.imap_mail/ but the message I wanted to save got _lost_, /home/$user/.imap_mail/Drafts stays at zero bytes. The next message I try to save as draft finds its way to the Drafts mbox however. Please note that no /home/$user/.imap_mail/inbox has been created although a inbox is shown in Thunderbird. When I move the saved message from Drafts to the inbox folder shown in Thunderbird, it gets saved in /var/mail/$user instead of /home/$user/.imap_mail/inbox, I guess this is due to the use of the mbox_snarf plugin, right? /home/$user/.imap_mail/inbox is the maildrop for Exim, which handles incoming mails, but in this scenario the user did not receive any emails yet. If I manually create /home/$user/.imap_mail/inbox, then moving a message from Drafts to the Thunderbird-displayed inbox works. How to fix this problem? Especially messages getting lost is really bad because I am in the process of changing our mail server setup from Exim/UW-Imapd to Exim/Dovecot, where I have to move 100+ /var/mail/$user mbox files to /home/$user/.imap_mail/inbox. But when Dovecot can not properly save files to previous non-existing mbox files, like Drafts, this is really a problem.

[Dovecot] IP based virtual users: stripping login domain?
by Alan Ferrency 17 Sep '07

17 Sep '07

Hello. I have a likely unusual request regarding IP based virtual dovecot users. When you specify a passdb passwd-file name containing "%d", then the domain portion is stripped from the login username, before the user is checked in the passwd-file. However, if you specify a passwd-file name containing "%l" (the local IP), the domain portion of the login is not stripped off before the username is checked in the passwd-file. This behavior makes sense, and should be considered the right and proper thing to do. But in this case, I want to do something different anyway. In the setup I'm working on, most logins will use domain based virtual usernames. However, if a customer logs in with an unknown domain in their login username, I'd like to fall back to IP-based virtualization, based on the local IP they connect to. I can't use auth_username_format to strip off %d, because that would break the domain based virtualization. What I need is an option to make %l work the way %d already works; or a format inside a passwd-file which allows for partial matches in the "username" column. If I can do this directly using a passwd-file, I'd like to do that. It seems like it'd be easy if I were using an SQL back end, but that's not an option. It's possible with an external authentication script, but I want to explore more direct configuration options, first. Does anyone have any recommendations? If what I want can't already be done, and I patched dovecot to do one of these things, how likely would it be to have that patch merged into the project? Thanks, Alan Ferrency pair Networks, Inc. alan(a)pair.com

http://dovecot.org/releases/1.1/alpha/dovecot-1.1.alpha6.tar.gz http://dovecot.org/releases/1.1/alpha/dovecot-1.1.alpha6.tar.gz.sig Most importantly doesn't crash anymore if both pop3 and imap aren't used. :) I'm hoping people won't find anything too bad from this release anymore, so I'll release v1.1.beta1 in a week or so. I also finally did some larger API changes and code cleanups that I had been planning on doing for a long time. I also changed copyright notices in the code to: /* Copyright (c) xxxx-2007 Dovecot authors, see the included COPYING file */ So my name isn't there anymore. It wasn't always correct anyway. I'm planning on updating the -2007 year at the beginning of each year to all the files. It's annoying to try to keep it updated manually.

[Dovecot] Dovecot stops talking to the auth server.
by Tom Diehl 17 Sep '07

17 Sep '07

Hi, I have an RHEL4 machine running dovecot-1.0.3 + postfix-2.3.2 + postfixadmin + mysql-4.1.20-2.RHEL4.1 + amavisd-new-2.5.2-1. The machine only has a gig of memory in it, I am trying to keep it running until I get new hardware to replace it in a couple of weeks. For the most part it works as advertised but every once in a while it stops talking to the auth server. I think I have tracked this to periods of high auth requests. Today the machine experienced a dictionary attack and I had log entries like the following: Sep 10 13:31:06 rocky dovecot: pop3-login: Disconnected: Shutting down: rip=::ffff:24.0.201.240, lip=::ffff:192.168.0.16 Sep 10 13:31:06 rocky dovecot: pop3-login: Can't connect to auth server at default: Resource temporarily unavailable Sep 10 13:31:07 rocky last message repeated 47 times Sep 10 13:31:08 rocky dovecot: pop3-login: Disconnected: Shutting down: rip=::ffff:24.0.201.240, lip=::ffff:192.168.0.16 Sep 10 13:31:08 rocky dovecot: imap-login: Can't connect to auth server at default: Resource temporarily unavailable Sep 10 13:31:08 rocky dovecot: pop3-login: Can't connect to auth server at default: Resource temporarily unavailable Sep 10 13:31:09 rocky last message repeated 27 times Sep 10 13:31:09 rocky dovecot: imap-login: Can't connect to auth server at default: Resource temporarily unavailable Sep 10 13:31:09 rocky dovecot: pop3-login: Can't connect to auth server at default: Resource temporarily unavailable Sep 10 13:31:09 rocky last message repeated 4 times Sep 10 13:31:09 rocky dovecot: imap-login: Can't connect to auth server at default: Resource temporarily unavailable ... a ps showed numerous defunct processes similar to the following: ... nobody 16647 0.0 0.2 9784 2112 ?

[Dovecot] Dovecot Sieve crash
by Julian Cowley 16 Sep '07

16 Sep '07

I just transferred the files in my home directory from an x86_64 machine to an i686 machine. This included the .dovecot.sieve and .dovecot.sievec files in my home root, and the Dovecot index files in my ~/Maildir directory. Everything seemed to be working until I tried sending an email that triggers a Sieve "redirect" command, then I got the following in the logs. I then tried the same dovecot.sieve file using a separate account which has always been on the i686 machine (and the index files have always been written there too), and the Sieve "redirect" worked fine. There were core files written in my home directory which I can post if necessary. Both the x86_64 and i686 machines are CentOS 4.5 running Dovecot 1.0.5 and Dovecot Sieve plugin 1.0.1.

[Dovecot] Dovecot Periodically Stops Authenticating Users
by David Gitman 16 Sep '07

16 Sep '07

Hi, It seems that my dovecot installation periodically stops authenticating users. Restarting dovecot resolves the issue temporarily. I'm authenticating via PAM to OpenLDAP on a CentOS 4 box. I've seen several related posts about this issue but no resolution. My logs show: Sep 15 03:58:24 server01 dovecot: imap-login: Can't connect to auth server at default: Resource temporarily unavailable Sep 15 03:58:24 server01 dovecot: imap-login: Can't connect to auth server at default: Resource temporarily unavailable And my configuration is: /usr/sbin/dovecot --version 1.0.3 /usr/sbin/dovecot -n # 1.0.3: /etc/dovecot.conf login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login mail_location: maildir:~/mail mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 auth default: passdb: driver: pam userdb: driver: passwd Any ideas on how to resolve this?

[Dovecot] Migration woes from tpop mbox to dovecot maildir
by Chris Richardson 16 Sep '07

16 Sep '07

I was hoping some one might be able to offer me some advice on a little problem I have. I am looking to A. move from mbox to maildir B. looking to move from tpop to dovecot to bring both pop and imap under the same program. anyways the problem I am having is this tpop3d mbox uses MD5 sum of the mailbox headers in hex which is option %m in the uidl section but the problem is when dovecot convert plugin runs and makes in a maildir it fails to find the md5 of this because it is only used for mboxs. if I change this from %m to %Mf it downloads every message on the clients computer which is not desirable. I was thinking only options i have is to allow it to download all them mail and or write a script to convert it to maildir or another pop servers uidl. but i dont know much about how other pop servers generate there headers. so I was hoping maybe some one has done something similar to this or could offer some input. thanks -Chris The information transmitted is intended only for the person or entity to which it is addressed and may contain confidential and/or privileged material.

Hi, sorry for this question, but I didn't find the information in the documentation or wiki: Is mailbox_idle_check_interval (in dovecot.conf) in seconds or minutes? I think it's minutes. But ... It would be nice, if this will be in the docu of the dovecot.conf. Thanks Rupert

http://dovecot.org/releases/1.0/dovecot-1.0.5.tar.gz http://dovecot.org/releases/1.0/dovecot-1.0.5.tar.gz.sig v1.0.4 was a bit bad release. - deliver: v1.0.4 broke home directory handling - maildir: Creating mailboxes didn't use dovecot-shared's group for cur/new/tmp directories.

[Dovecot] v1.1.alpha5 released
by Timo Sirainen 15 Sep '07

15 Sep '07

http://dovecot.org/releases/1.1/alpha/dovecot-1.1.alpha5.tar.gz http://dovecot.org/releases/1.1/alpha/dovecot-1.1.alpha5.tar.gz.sig I think we're finally close to v1.1.betas. - Fixed "messages_count too large" index errors. - deliver was crashing. - Saving messages with maildir accessed freed memory, which might have caused crashes. - Index files are now never marked as "corrupted". Instead fsck is run which preserves as much of the original index as possible. This is important with dbox at least since index files are the only place where the latest flag/keyword changes are. Recent alphas were also modifying process's fd limits. The current behavior is: - If current fd limit is less than login_max_processes_count (imap +pop3) + max_mail_processes, log a warning at startup: "fd limit 1024 is lower than what Dovecot can use under full load (more than 1234). Either grow the limit or change login_max_processes_count and max_mail_processes settings" - Since 1024 is a common default limit, I dropped max_mail_processes default to 512. - Login processes drop their fd limit to the maximum number of fds needed, plus a few more just in case.

[Dovecot] Proxy problems with 1.0.5 !
by Ed W 15 Sep '07

15 Sep '07

Hi I am trying to do a staged migration over to dovecot, but having troubles at the first hurdle. I setup the proxy feature to redirect most of our users back to the current Courier imap/pop server, and it's partly working, but I'm getting some serious errors using Thunderbird and IMAP. Now, I had expected the proxying to be fairly transparent and basically just dovecot doing an auth and then passing the stream on to the other server? My problem is that using Thunderbird I can read all my folders OK, but I can't save anything in my Sent Items or Drafts folders... Basically I get errors every time I try and send an email, or try to save to the draft folder. Curiously, directly browsing into those folders works fine, as does deleting emails, and apparently copying them works fine also... Why is the saving of sent messages failing...? The setup is basically taking a working Thunderbird install, changing the server name from pointing at the Courier server to point at the dovecot server - dovecot in turn is told to proxy back to the original server. All I'm getting from Thunderbird is an "Invalid Command" response. Is there an easy way to get a look inside the imap stream to try and see what's failing? Any suggestions on why this is happening at all? One idea is that I have setup completely different namespaces in Dovecot, (with a hidden namespace which should be courier compatible), but I wouldn't have expected this to affect the Proxy stuff at all?! Grateful for any pointers to debug this - it's a fairly major hurdle for my rollout Thanks Ed W

[Dovecot] auth_default_realm for different listeners
by John Morrissey 15 Sep '07

15 Sep '07

We provide POP3 service for several realms, each of which has a substantial number of users logging in with no realm (bare username). We would like to use Dovecot, but I haven't been able to findout how to vary auth_default_realm for each listener. My most recent attempt was to set up one auth {} block for each realm with a different auth_default_realm and socket master path. I then set up one protocol pop3 {} block for each realm, listening on different IP addresses and with a auth_socket_path corresponding to the auth block for that listener. I'm not sure if I'm on the right track here, but I'm seeing two problems: 1. When dovecot starts, I get: Sep 5 18:32:21 pop01 dovecot: auth(otherdomain): Socket already exists: /var/run/dovecot/auth-otherdomain for each additional auth {} block. 2. dovecot won't start with auth_socket_path specified in a protocl pop3 {} block: Error in configuration file /etc/dovecot/dovecot.conf line 654: Unknown setting: socket_path Is there a way to vary auth_default_realm for each listener, so I can have multiple realms log in with bare usernames? thanks, john -- John Morrissey _o /\ ---- __o jwm(a)horde.net _-< \_ / \ ---- < \, www.horde.net/ __(_)/_(_)________/ \_______(_) /_(_)__

[Dovecot] namespace prefix issue with avelsieve
by it-dovecot＠ml.epigenomics.com 15 Sep '07

15 Sep '07

Hi! I am currently testing a setup with dovecot's lda, the cmusieve plugin, pysieved and the avelsieve plugin for squirrelmail. The issue I am stumbling upon is that avelsieve is generating folder names including the namespace prefix when creating "fileinto" rules. E.g.: A rule: If the header "Precedence" contains "bulk", then file it into the folder INBOX.bulk. Also keep a copy in INBOX, marked as deleted. translates into sieve: require ["fileinto","reject","vacation","imapflags","relational","comparator-i;ascii-numeric","regex","notify"]; if header :contains "Precedence" "bulk" { fileinto "INBOX.bulk"; addflag "\\Deleted"; keep; } But what happens when a matching email is delivered is that a new mailbox ".INBOX.bulk" in the user's Maildir is created. I.e. the email is not delivered to ~/.Maildir/.bulk as intended, but into ~/.Maildir/.INBOX.bulk, creating the new folder on the fly. The same happens when trying to fileinto folders from other namespaces. It seems that either avelsieve is generating "too much" and should remove the prefix (at least for INBOX) or dovecot's deliver is not able to use the namespaces definition in dovecot.conf correctly when interpreting sieve's fileinto directive. Did I miss something? This is the dovecot.conf in use: # /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S listen: *:143 ssl_listen: *:993 ssl_cert_file: /etc/courier/imapd.pem ssl_key_file: /etc/courier/imapd.pem disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login login_processes_count: 12 login_max_processes_count: 512 verbose_proctitle: yes mail_location: maildir:~/.Maildir:INDEX=/var/cache/dovecot/INBOX.%u:CONTROL=/var/cache/dovecot/INBOX.%u mail_full_filesystem_access: yes maildir_stat_dirs: yes maildir_copy_with_hardlinks: yes namespace: type: private separator: . prefix: INBOX. inbox: yes namespace: type: public separator: . prefix: shared. location: maildir:~/.Maildir/shared:INDEX=/var/cache/dovecot/shared.%u:CONTROL=/var/cache/dovecot/shared.%u namespace: type: private separator: . prefix: archive. location: maildir:/mnt/nfs/imap_archive.hm/%u:INDEX=/var/cache/dovecot/archive.%u:CONTROL=/var/cache/dovecot/archive.%u auth default: verbose: yes passdb: driver: passwd userdb: driver: passwd socket: type: listen client: path: /var/run/dovecot/auth-client mode: 432 master: path: /var/run/dovecot/auth-master mode: 384 Greetings -- Robert Sander Senior Manager Information Systems Epigenomics AG Kleine Praesidentenstr. 1 10178 Berlin, Germany phone:+49-30-24345-0 fax:+49-30-24345-555 http://www.epigenomics.com robert.sander(a)epigenomics.com

Re: [Dovecot] Dovecot / OS X 10.4 Mail.app and "Too Many Opened files" error message ?
by Xavier Beaudouin 14 Sep '07

14 Sep '07

(replying to myself) > After a long time, the OS X client say error : "Too Many opened > files". Seems that OS X has stupidly low number of files that can be opened... $ ulimit -a [...] open files (-n) 256 On my MacBook Pro.... This is bloody low.... So I've figured to change this limit globaly, but it seems that OS X don't have any limits.conf or default values.... This kinda strange.. So I decided to do some local fixe for Mail.app only : in /Applications/Mail.app/Contents/MacOS/ $ sudo mv Mail Mail.orig and ... Create a Mail file with this following content : #!/bin/sh # thanks to http://www.amug.org/~glguerin/howto/More-open-files.html # To understand this, read 'man sh' below "substring processing". # This can also be accomplished with the 'dirname' command, # but it may not be installed. here="${0%/*}" # This should be the name of your native Java-app's executable. cmd='Mail.orig' # Set all desired soft-limits here. See 'ulimit' in 'man sh'. ulimit -S -n 1000 # Execute the Java-app in the current process. See 'exec' in 'man sh'. exec "$here/$cmd" "$@" $ sudo chmod +x Mail and this all... FYI Mail.app is really strange thing.... $ lsof | grep Mail.orig | wc -l 150 Mostly all libraries and TCP connection to mail server... Maybe this can be added to Wiki even if it is not too mutch dovecot related, but can be usefull for people like me that does have lots of mail.... /Xavier

[Dovecot] gssapi, kerberos and webmail
by Denis Cardon 14 Sep '07

14 Sep '07

Hi every one, first thanks for the great job, I switched successfully from courier imap a few months ago and both the migration and maintenance went smoothly from then on. The reason I switched was gssapi support (and the easier debug) and now I have thunderbird on Linux connecting in an SSO fashion through kerberos/GSSAPI (works great). Users should be able to access their mail throught a webmail too (eg. eGroupware). I have already checked for kerberos authentication on Apache, however there seems to be no way to have ticket forwarding throught PHP. AFIAK there is thus no way to use kerberos for php-imap --> dovecot authentication. The only information available seems to be the username. So here is my question : how do people on this mailing list handle kerberos authentication with webmail? Do you use other kind of authentication on privileged port (ie with access only from apache) and just do a login/nopassword authentication (like an uid base authentication through ldapi:/// on an ldap directory for example) ? Here is what we have with thunderbird : Thunderbird -------kerberos-------> dovecot on standard port Here is what I would guess for webmail auth : Firefox ------kerberos----> Apache ----gssapi-auth-just-using-login----> dovecot on privileges port Cheers, Denis -- Denis Cardon Tranquil IT Systems 44 bvd des pas enchantés 44230 Saint Sébastien sur Loire tel : +33 (0) 2.40.97.62.67 http://www.tranquil-it-systems.fr

Hello, I am trying to move from Courier-imap to dovecot.... Even if the processes to move logical (eg name spaces etc...) went very and without any problem, I've some etrange behavior when Imap client is Mac OS X Mail.app. I've got a big mailbox that have about 3 / 4G of mail in several folder (lots !!!)... After a long time, the OS X client say error : "Too Many opened files". I have check on the servers (a FreeBSD farm of 3 servers using freebsd ports of dovecot)... And nothing special... A question : why do I have never this kind of message on courier imap and why do I get this on dovecot... ? Configuration file on demand... if needed... THanks, /Xavier

[Dovecot] pipe() error but not linked to kqueue
by Patrick Milvich 14 Sep '07

14 Sep '07

I have dovecot 1.0.5 installed on an OpenBSD 4.1 box and an OS X Server 10.4.10 box. Sure you've all heard it before, because of the pipe error, no more login processes can be launched, and I have to restart the server. dovecot: Sep 13 05:50:00 Error: pipe() failed: Too many open files I first thought this was the issue with kqueue, but I've since recompiled making sure to use poll. This also happened with 1.0.3 and 1.0.2. It also happens very specifically after a dictionary attack that lasts usually about an hour, unless I can catch it earlier. (Around 18,000 login attempts) ex: dovecot: Sep 13 05:49:58 Info: pop3-login: Aborted login: user=<aaron>, method=PLAIN, rip=62.161.41.32, lip=<local ip> dovecot: Sep 13 05:49:58 Info: pop3-login: Aborted login: user=<adm>, method=PLAIN, rip=62.161.41.32, lip=<local ip> dovecot: Sep 13 05:49:58 Info: pop3-login: Aborted login: user=<account>, method=PLAIN, rip=62.161.41.32, lip=<local ip> But after the attack has subsided for a period of time, I still have the number of file descriptors maxed out for the dovecot process. I've increased the number available to have a higher roof, but that doesn't fix the problem. Wondering if anyone else has seen this issue, and also in a generic problem. How are others dealing the the problem of being attacked in this method? Is there a max number of login tries for a given ip address within a period of time that I'm missing? :) Thanks, Patrick

[Dovecot] dirsize quota assertion problem
by Alan Ferrency 14 Sep '07

14 Sep '07

Our current virtual mailbox configuration is not compatible with one of the assertions in the dovecot quota plugin's assertions in quota-dirsize.c. I believe the assertion is incorrect, but I would also be happy if I could get the same result with a better configuration setting. Here is a sample passdb entry which causes the quota assertion to fail: test(a)example.com:<snip>:3007:1000::/usr/boxes/username/example.com::userdb_mail=mbox:~/test^/.imap:INBOX=~/test userdb_uid=3007 userdb_gid=1000 userdb_home=/usr/boxes/username/example.com userdb_quota=dirsize:storage=100 The imap folder is "~/test^/.imap" and the INBOX is "~/test". As you can see, these are in different locations, but the INBOX string happens to be a substring of the imap folder directory. An example of the failed assertion error: Aug 31 16:44:13 www2 dovecot: IMAP(test(a)example.com): file quota-dirsize.c: line 180 (quota_count_path_add): assertion failed: (!is_file) This particular error log line was generated by dovecot 1.0.3, but the code in quota-dirsize.c is the same in dovecot 1.1 alpha3's version of quota-dirsize.c: 131 if (strncmp(count_path[i].path, path, strlen(path)) == 0) { 132 /* the new path contains the existing path */ 133 i_assert(!is_file); 134 count_path += i; 135 break; 136 } First, quota_count_path_add() is called for directory "~/test^/.imap" and it succeeds. When it is subsequently called for file "~/test": - the strncmp matches because "~/test" is a substring of "~/test^/.imap" - the assertion fails because "~/test" is a file and not a directory It seems to me that instead of asserting !is_file, it would be better to simply skip the conditional in that case, since a path variable that is a file should never be tested to see whether it contains an existing path. if (!is_file && strncmp(count_path[i].path, path, strlen(path)) == 0) { /* the new path contains the existing path */ count_path += i; break; } But this also has a bug: if path is a directory which substring matches count_path[i].path, but the same path with a directory separator appended to it does not substring match count_path[i].path, then it is a different path and does not contain the existing path. For example, if count_path[i] is the directory /usr/home/test/mailbox_folders, and path is the directory /usr/home/test/mailbox, then /usr/home/test/mailbox does not contain/usr/home/test/mailbox_folders, and this condition should fail. If some other code were to enforce that /usr/home/test/mailbox be terminated with a directory separator, then this is not a problem and my patch should work. I hope this makes sense.

[Dovecot] Dovecot + virtual users
by bichumo 13 Sep '07

13 Sep '07

Hi, I'm running FreeBSD, Dovecot, Postfix (virtual users), MySQL, Squirrelmail. I have installed squirrelmail-quota_usage-plugin, but I cannot make it work. It mentions "If you have an IMAP server with QUOTA Extension capability...". In dovecot.conf I have enabled "mail_plugins = quota" near protocol pop3 and protocol lda, near protocol imap I have "mail_plugins = quota imap_quota". Near " plugin { ..." I have "quota = maildir:storage=204800". I think that the problem of why I don't see quota in Squirrelmail is in file dovecot-sql near user_query. I have my users mailboxes in such format: /usr/local/virtual/domain.tld/username and my user_query looks like this: user_query = SELECT maildir, 125 AS uid, 125 AS gid, concat('maildir:storage=', quota) AS quota FROM mailbox WHERE username = '%u' AND active = '1', I think that in my user_query I'm missing something. I do not get any errors in the dovecot and dovecot-debug logs, everything works fine, but I still can't see quota.

[Dovecot] Datehandling bug?
by Ed W 12 Sep '07

12 Sep '07

Hi, I am testing dovecot 1.0.3 alongside my existing courier installation and a number of my emails are heading to the top of the inbox even though they are rather old. Closer inspection shows that my mailclient (Thunderbird on Win32) is showing me some screwey dates for a number of messages. One example is an email which says: Date: 2007-08-21 11:42:43 But in TB I see the date shown as only: 03:27 ie just a time and no date OK, the date above is clearly not an RFC date, but any idea why this is showing up only under Dovecot? Is it a dovecot date handling issue? Cheers Ed W

[Dovecot] Deliver parameter problem
by Umut Arus 11 Sep '07

11 Sep '07

Hello, I'm using dovecot-1.0.5 with postfix. I have to use deliver from procmail because I have some filters. There is no document about how to using deliver parameters (-d) other than http://wiki.dovecot.org/LDA . If I set -d parameters manually as a username everything is ok. I can not set users' mail quota (don't lookup) with mysql db if I haven't set -d parameter as receipt username in procmail. How can I describe user (-d) parameter's variable in procmail?

[Dovecot] postfix + dspam + dovecot problem
by Lars Stavholm 11 Sep '07

11 Sep '07

Hi All, I'm new to dovecot (coming from cyrus) and have a bit of a problem setting up postfix + dspam + dovecot. 1. postfix + dovecot: works like a charm. Using "mailbox_command = /usr/lib/dovecot/deliver" in postfix main.cf 2. adding dspam to the equation: unable to deliver: net_connect(/usr/var/run/dovecot/auth-master) failed: No such file or directory Using "mailbox_transport = lmtp:unix:/var/tmp/dspam.sock" in postfix main.cf (instead of the above mailbox_command), and the corresponding setting in master.cf. In /etc/dspam.conf I'm using... TrustedDeliveryAgent "/usr/lib/dovecot/deliver" And here's the full error message: Sep 11 02:10:38 nwinnie postfix/pickup[18313]: 090F1C042: uid=0 from=<root> Sep 11 02:10:38 nwinnie postfix/cleanup[7010]: 090F1C042: message-id=<20070911001038.090F1C042(a)nwinnie.telcotec.se> Sep 11 02:10:38 nwinnie postfix/qmgr[18318]: 090F1C042: from=<root(a)nwinnie.telcotec.se>, size=431, nrcpt=1 (queue active) Sep 11 02:10:38 nwinnie deliver(stava(a)nwinnie.telcotec.se): net_connect(/usr/var/run/dovecot/auth-master) failed: No such file or directory Sep 11 02:10:38 nwinnie dspam[10379]: Delivery agent returned exit code 75: /usr/lib/dovecot/deliver -d stava(a)nwinnie.telcotec.se Sep 11 02:10:38 nwinnie postfix/lmtp[7018]: 090F1C042: to=<stava(a)nwinnie.telcotec.se>, orig_to=<stava>, relay=nwinnie.telcotec.se[/var/tmp/dspam.sock], delay=0.35, delays=0.32/0.01/0.01/0.01, dsn=4.3.0, status=deferred (host nwinnie.telcotec.se[/var/tmp/dspam.sock] said: 421 4.3.0 <stava(a)nwinnie.telcotec.se> Delivered (in reply to end of DATA command)) So, postfix hands the message to dspam, dspam does its thing, dspam tries to deliver and fails. What throws me is that the delivery works as expected in case 1) but not in case 2), despite the fact I'm using the same delivery agent, i.e. /usr/lib/dovecot/deliver. Why would dovecot go for some other authentication method in case 2)? BTW, we're using PAM on top of LDAP. Any ideas appreciated. Cheers /Lars

[Dovecot] Write-only mailboxes
by Steffen Kaiser 11 Sep '07

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, I've setup a mailbox for reporting SPAM by simply symlinking it into the Maildir of selected users. In order to preserve anonymity of the users I setup the mailbox as follows: drwxr-xr-t 5 root fb 4096 2007-09-05 16:18 ./ drwxr-xr-x 7 root root 4096 2007-09-05 16:16 ../ drwx-wx-wt 2 spamd fb 12288 2007-09-10 16:17 cur/ hence, with read permission for the spam bot only. When Thunderbird copies mails from the same mail account into the folder, it seems like it tries to select the mail box afterwards, then a "Internal error occured. Refer to server log for more information." because of permission denied. When one copies mail from yet another account into the SPAM box, no such message appears. I guess, Thunderbird does not try the refresh the message count. Well, is there a possiblity to setup a Write-Only mailbox, with Dovecot v1.0.3 with the ACL plugin? Is there a working setup for write-only mailboxes with the ACL plugin?

[Dovecot] multiple emails
by dhottinger＠harrisonburg.k12.va.us 10 Sep '07

10 Sep '07

I have a weird issue where several users are recieving the same email's multiple times. Each email has a different que id, but are exactly the same otherwise. I thought at first this was a new spam, but I have local users doing the same thing. Im not sure where to start looking for the root of this problem. Seems to be pretty widespread across multiple platforms. I currently utilize openldap for user database, sendmail, Dovecot-Imap, and horde webmail. Im not sure where to start digging for this problem, Ive scanned through all my log files and havent found anything. Any guidance would be great. thanks, ddh -- Dwayne Hottinger Network Administrator Harrisonburg City Public Schools

Hello, I'm using dovecot-1.0.5 with postfix. There is no document about how to using deliver parameters (-d). I can not set mail quota with mysql db if I haven't set this parameter. How can I describe user (-d) parameter to procmail. Procmail set, :0 | /usr/local/dovecot/libexec/dovecot/deliver -f blabla -d blabla regards,

[Dovecot] Courier Migration
by Ed W 09 Sep '07

09 Sep '07

Hi Is it legal/sensible to use the following in the conf file # default namespace namespace private { separator = / prefix = inbox = yes } # for backwards compatibility: namespace private { separator = . prefix = INBOX. inbox = yes hidden = yes } The goal would be to migrate away from an Courier server, whilst still supporting clients using their old settings, but going forward they can use the new settings? In particular I always noticed that OE would not set the namespace automatically, so being able to leave it blank would be an advantage (fewer config issues for customers) Grateful if someone could confirm this works ok? Compatibility issues with Thunderbird/OE/Outlook 2003+ in particular? Cheers Ed W

Hi, We are using dovecot version 1.0.3. We have dovecot-ldap configured to authenticate users using ldap database. We are facing the inactivity problem with dovecot. After some hrs of successful working, dovecot logs shows the connection inactive problem with pop3 & imap server, & it starts rejecting the connection requests from clients. The problem goes away once we restart dovecot. The problem occurs again & again after some random time. Please help us in solving this problem.

[Dovecot] shared mailbox subfolder permissions
by David Leuschner 09 Sep '07

09 Sep '07

Hi all, when I create a subfolder in a public mailbox the dovecot-shared file is copied for the newly created subfolder and all mails get the owner, group and permissions from the file. Unfortunately the cur, new and tmp folders only get the permissions from the file but owner and group are set according to the creator. This effectivly makes the folder private to the creator. Is this the intended behavior? Is it a bug that has already been fixed in a later version? I am using 1.0.rc29. An example follows. Thanks for your help! David As an example .foobar was created manually (maildirmake) and permissions were setup using the shell: uml public # ls -al . .foobar .: total 24 drwxrwx--- 6 root pub 4096 Aug 18 13:05 . drwxrwxr-x 3 root mail 4096 Aug 18 11:10 .. drwxrwx--- 5 root pub 4096 Aug 18 11:42 .foobar drwxrwx--- 2 root pub 4096 Aug 18 10:50 cur -rw-rw---- 1 root pub 0 Aug 18 11:40 dovecot-shared drwxrwx--- 2 root pub 4096 Aug 18 10:50 new drwxrwx--- 2 root pub 4096 Aug 18 10:50 tmp .foobar: total 20 drwxrwx--- 5 root pub 4096 Aug 18 11:42 . drwxrwx--- 6 root pub 4096 Aug 18 13:05 .. drwxrwx--- 2 root pub 4096 Aug 18 11:42 cur drwxrwx--- 2 root pub 4096 Aug 18 11:42 new drwxrwx--- 2 root pub 4096 Aug 18 11:42 tmp After creating a subfolder 'baz' with Thunderbird the group of .baz is the group from dovecot-shared but the contained new/cur/tmp directories have the users primary group (instead of pub). uml public # ls -al . .baz .: total 28 drwxrwx--- 7 root pub 4096 Aug 18 13:09 . drwxrwxr-x 3 root mail 4096 Aug 18 11:10 .. drwxrwx--- 5 dleuschner pub 4096 Aug 18 13:09 .baz drwxrwx--- 5 root pub 4096 Aug 18 11:42 .foobar drwxrwx--- 2 root pub 4096 Aug 18 10:50 cur -rw-rw---- 1 root pub 0 Aug 18 11:40 dovecot-shared drwxrwx--- 2 root pub 4096 Aug 18 10:50 new drwxrwx--- 2 root pub 4096 Aug 18 10:50 tmp .baz: total 20 drwxrwx--- 5 dleuschner pub 4096 Aug 18 13:09 . drwxrwx--- 7 root pub 4096 Aug 18 13:09 .. drwxrwx--- 2 dleuschner dleuschner 4096 Aug 18 13:09 cur -rw-rw---- 1 dleuschner pub 0 Aug 18 13:09 dovecot-shared drwxrwx--- 2 dleuschner dleuschner 4096 Aug 18 13:09 new drwxrwx--- 2 dleuschner dleuschner 4096 Aug 18 13:09 tmp Here's my configuration: listen: localhost ssl_listen: * ssl_ca_file: /root/ca/ca.crt ssl_cert_file: /root/ca/crt/uml.crt ssl_key_file: /root/ca/keys/uml.key ssl_verify_client_cert: yes verbose_ssl: yes login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login namespace: type: private separator: . prefix: Priv. location: maildir:~/.maildir:CONTROL=~/.maildir/ctrl/priv:INDEX=~/.maildir/idx/priv inbox: yes namespace: type: public separator: . prefix: Pub. location: maildir:/var/mail/public:CONTROL=~/.maildir/ctrl/pub:INDEX=~/.maildir/idx/pub auth default: passdb: driver: pam args: * userdb: driver: passwd socket: type: listen client: path: /var/run/dovecot/auth-client mode: 432 master: -- David Leuschner Meisenweg 7 79211 Denzlingen Tel. 07666/912466

[Dovecot] SSL connections frozen on Dovecot 1.0.0
by Thibault VINCENT 09 Sep '07

09 Sep '07

Hello, We are running Dovecot 1.0.0 (Debian Etch, Backports.org, OpenSSL) in a production environment and we experience sporadic SSL connection problems. At the moment, it's difficult to tell if the server goes back to normal operation after some time or if it can be reproduces at any time because we have to restart it as soon as we get Nagios alerts. Some tests with openssl s_client have shown difficulties to proceed the SSL handshake (hanging at different stages), or no response to IMAP commands. SSL client used: openssl s_client -host imap -port 993 - First case : s_client hangs on the first output "CONNECTED(00000003)" and there is no handshake at all; - Second case : like the first but the handshake starts after a few minutes; - Third case : the handshake goes fine but the "OK" server banner is never sent (no response to commands); - Fourth case : the greeting banner is received but dovecot will never answer. The configuration file is almost identical to the default and SSL certificate is not the autogenerated one. Log files do not show dying process. I've searched the ML archive for SSL issues but not found related bug. Does anyone use the Backport.org package of Dovecot ? Thank you :) -- Thibault VINCENT tibal(a)reloaded.fr thibault.vincent(a)reloaded.fr PGP Key : 0x4BA8A39B

[Dovecot] postfix + dovecot lda,
by Michael Moritz 09 Sep '07

I'm trying to replace procmail with deliver but I'm having problems with the group part of things. I keep getting: Aug 29 16:44:19 dingbat deliver(mimo): open(/var/mail/.temp.dingbat.3969.d1689935a308e0dd) failed: Permission denied Aug 29 16:44:19 dingbat deliver(mimo): file_lock_dotlock() failed with mbox file /var/mail/mimo: Permission denied My primary group is mimo and I think it's trying to use that. I changed it to mail and things work. But I do not want all my users to have a primary group mail. Is there a way I can force deliver to use group mail as group and ignore the per user gid? I tried chmod 6755 /usr/lib/dovecot/deliver but no change. This is on debian/etch, help appreciated.... mimo

Hi folks, My institute's mail server was upgraded to RHEL5 with dovecot 1.0-2.1rc5 recently. And it uses PAM authentication which points to LDAP server. Now from time to time it gets Error like dovecot: Aug 29 09:23:59 Error: auth(default): pam(joshua,192.168.177.52): pipe() failed: Too many open files and users can not login. My config is like dovecot -n # /etc/dovecot.conf base_dir: /var/run/dovecot/ log_path: /var/log/dovecot info_log_path: /var/log/dovecot listen: * login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login login_greeting: ASIAA Dovecot ready. login_processes_count: 4 mail_location: mbox:/asiaa/home/%u/:/asiaa/home/%u/mail/:INBOX=/var/mail/%u:INDEX=/asiaa/home/%u/mail/dovecot_indexes mail_debug: yes mail_full_filesystem_access: yes mail_drop_priv_before_exec: yes mail_executable(default): /etc/dovecot_postlogin_beforeimap.sh mail_executable(imap): /etc/dovecot_postlogin_beforeimap.sh mail_executable(pop3): /etc/dovecot_postlogin_beforepop3.sh mail_process_size: 512 mail_plugin_dir(default): /usr/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 pop3_uidl_format(default): %08Xu%08Xv pop3_uidl_format(imap): %08Xu%08Xv pop3_uidl_format(pop3): %08Xv%08Xu auth default: passdb: driver: pam userdb: driver: passwd Any suggestion or help is appreciated Cheers Joshua

It doesn't work with '+' delimited address+extension >(I reported it in this list, but had no replies). Actually I managed to fix this setting global_script_path = /usr/local/etc/sieve/Junk instead of sieve_global_dir = The emails marked as spam were moved to correct directory which is Junk, as listed in user's subscriptions file and not INBOX.Junk. I also correcred my sieve file to say: require ["fileinto"]; # Move spam to Junk folder if header :contains ["X-DSPAM-Result"] "Spam" { fileinto "Junk"; # Stop here so that we do not reply on spams stop; } But now I can see following logs for some of the accounts.

[Dovecot] Don't let deliver create index files
by Martin Strand 09 Sep '07

09 Sep '07

For various reasons I want to use deliver with Postfix and Courier-IMAP, and it seems to work fine except for one thing: deliver creates some dovecot.* index files that Courier never uses (and I assume deliver doesn't need them) Is there a way to prevent that? Thanks, Martin

[Dovecot] Using NID_x500UniqueIdentifier as ssl_username_from_cert
by S. Wefel 09 Sep '07

09 Sep '07

Hi, please have a look at the attached patch for dovecot-1.0.3 These patch modifies ssl_proxy_get_peer_name() to use the NID_x500UniqueIdentifier as username instead of NID_commonName. The reason is, that the Common Name doesn't have to be unique for the whole mailserver. Example; in germany a lot of people got the first name "Andreas" and the last name "Schulz". Therefore a lot of certificates exists with subjects like this: C=DE,O=ABC,CN=Andreas Schulz/emailAddress=andreas.schulz(a)abc.de C=DE,O=DEF,CN=Andreas Schulz/emailAddress=andreas.schulz(a)def.de ... dovecot couldn't distinguish between these users. So we decide to use certificates with an X509v3 extension NID_x500UniqueIdentifier which allows to extend the subject by an unique ID, e.g. the unix-uid or a database unique key. The new certificates may look like this: C=DE,O=ABC,CN=Andreas Schulz/emailAddress=andreas.schulz(a)abc.de/x500UniqueIdentifier=user1 C=DE,O=DEF,CN=Andreas Schulz/emailAddress=andreas.schulz(a)def.de/x500UniqueIdentifier=user2 With the attached patch the user is taken from this extension and e.g. with userdb=ldap you can use the filter string user_filter = (&(objectClass=posixAccount)(uid=%u)) A good solution to use booth, the common name and the UniqueIdentifier is to extend settings like ssl_username_from_cert = no | yes | cn | uid where "yes" is similar to "cn".

[Dovecot] Server Timed Out: Outlook Express
by Jackie Hunt 09 Sep '07

09 Sep '07

Hi all, We just started running Dovecot this fall here on campus v 1.0. I've started getting some trouble reports from users. An Outlook Express users reported seeing the "Server has not responded in 60 seconds" messages. Waiting longer doesn't help, he has to stop/start Outlook Express to get connected again. Also have a Thunderbird user who is seeing that type of behavior first thing in the morning after being logged in all night. He has to stop/restart Thunderbird. Also, have had some reports of "disconnected" showing up on the Outlook2007 status bar. I've looked at the Dovecot log, and don't see any errors. I do see lots of "Disconnected", "Disconnected in IDLE" and "Disconnected: Logged Out". These last two seem normal, if I just see "Disconnected" is that a flag that we're losing connections abnormally? I know version 1.0.3 is out. I've looked at the changes, and the only one I can see that might be related to what we are seeing is the IDLE commmand fix. Was hoping for some advice on whether upgrading might resolve these issue. Any insight would be greatly appreciated. Jackie --- Jackie Hunt ACNS Voice: (970) 663-3789 Colorado State University FAX: (970) 491-1958 Fort Collins, CO 80523 Email: jackie.hunt(a)colostate.edu

[Dovecot] LDA bouncing mails after upgrade -- again
by Milan Holzäpfel 09 Sep '07

09 Sep '07

Hi Timo, some time ago (2007-03-24 and following) I asked whether it was intended that Dovecot deliver bounces mails (by terminating with status 89) if the deliver version is older than the rest of the dovecot installation. You replied that it was a bug, and that it had been fixed in <URL:http://dovecot.org/list/dovecot-cvs/2007-March/008346.html>. When I upgraded from Dovecot 1.0.2 to 1.0.3 a few days ago, I found out that this problem probably still exists: | Aug 28 09:38:03 host.example.org deliver(user(a)example.org): Module is for different version 1.0.3: /usr/lib/dovecot/lda/lib10_quota_plugin.so | Aug 28 09:38:03 host.example.org postfix/pipe[18356]: <ID>: to=<user(a)example.org>, relay=dovecot, delay=0.4, delays=0.13/0.09/0/0.18, dsn=5.3.0, status=bounced (Command died with status 89: "/usr/libexec/dovecot/postfix-deliver/deliver") The error message I posted in march was: | Mar 22 20:29:20 host.example.org deliver(user(a)example.org): Module is for different version 1.0.rc27: /usr/lib/dovecot/lda/lib10_quota_plugin.so | Mar 22 20:29:20 host.example.org postfix/pipe[17344]: <ID>: to=<user(a)example.org>, relay=dovecot, delay=1.9, delays=1.5/0/0/0.35, dsn=5.3.0, status=bounced (Command died with status 89: "/usr/libexec/dovecot/postfix-deliver/deliver") I suppose you still want to fix it.

[Dovecot] processing Dovecot maildirs with shell scripts
by M. Fioretti 09 Sep '07

09 Sep '07

Hello, I have a postfix server which uses procmail as its delivery agent to deliver incoming messages to several maildirs. For several reasons, not really relevant here, I need to process/refilter/sort again the content of these mailboxes before delivering the messages to the _other_ maildirs which Dovecot sees and serves to local or remote imap users. Basically, I need to write some shell scripts that, from cron jobs, regularly do this: foreach file in some_incoming_mailbox/new/ do #process the file and/or set some variable according to its content delete the file or mv it to some_other_maildir/new/ where the actual action and value of some_other_maildir is set every time by the "process the file" part of the script. The part that I still miss is guidelines to do these things safely, that is without losing or corrupting messages or doing anything else that would confuse dovecot. For example, under which conditions it is sure to move or delete (the Unix way, with mv or rm) a message from mailbox1/new/ to mailbox2/new, when the latter is served via dovecot to remote users? What is advisable and most efficient? Use locks (how?), only work on file which are at least one minute old? Should I move the messages to tmp instead of new? What else? Tips or pointers about this are very welcome. Ciao, Marco

Hi, Whitbox Linux 3 (RHEL) Dovecot 1.0.rc29 Using NFS From time to time does all mail get re-downloaded to Thunderbird. I would believe this has something to do with an index problem. I upgraded to 1.0 a few months ago but that didn't work well so I installed version 1.0.rc29 which worked better but we still get this problem from time to time.

[Dovecot] passing quota to deliver via command line
by bill-dovecot＠carpenter.ORG 09 Sep '07

09 Sep '07

Is there any way to pass things like "quota=" for the quota plugin to the deliver LDA via the command line or as an environment variable or whatever? I've got all the info I need in my MTA to avoid a userdb lookup in the LDA, but I still have to do the userdb query to get the per-user quota number (the default quota works fine, of course). -- bill-dovecot(a)carpenter.ORG (WJCarpenter) PGP 0x91865119 38 95 1B 69 C9 C6 3D 25 73 46 32 04 69 D6 ED F3

[Dovecot] passdb/userdb args
by Daniel L. Miller 09 Sep '07

09 Sep '07

I'm a bit unclear on these - give me a moment to ramble on. I should mention I'm using version 1.0.3, my primary backend is LDAP, and I do NOT want to store user mail folders in my LDAP directory. I currently have the following: default_mail_env = maildir:/var/mail/%d/%n passdb ldap { args = /etc/dovecot/dovecot-ldap.conf } # Instructions for deliver state a userdb is still required if using prefetch userdb ldap { args = /etc/dovecot/dovecot-ldap.conf } userdb prefetch { } My dovecot-ldap.conf is pretty simple - the trimmed version is: hosts = localhost auth_bind = no user_attrs = %d/%n=mail user_filter = (mail=%u) pass_attrs = (&(userPassword=password)(mail=%u)) user_global_uid = 5000 user_global_gid = 8 I recognize that the pass_attrs is incorrect for a prefetch config - but I couldn't get it to work. My mail folder structure is /var/mail/domain/username. If, under 1.0.3, I can't use the %d/%n variables to build the user/home/mail parameters in the LDAP config, can I do it in the configuration stanza? Something like: passdb ldap{ args = home=%dn/%n mail=%d/%n /etc/dovecot/dovecot.conf } -- Daniel

I have a user that gets client timeout errors when he tries to delete/clean up his massive "Spam" folder (many thousands of mail messages). He uses Thunderbird and has it configured to use "Move to Trash" when he deletes messages. I find the following in Dovecot's log file when it happens: Aug 28 10:38:22 ifm.liu.se dovecot: [ID 107833 mail.error] IMAP(bpn): Timeout while waiting for lock for transaction log file /home/bpn/Maildir/.Trash/dovecot.index.log Aug 28 10:38:24 ifm.liu.se dovecot: [ID 107833 mail.info] IMAP(bpn): Disconnected Any suggestions on what I can tuned/fix in Dovecot to solve this issue?

[Dovecot] trouble with deliver in 1.0.4
by Jack Bailey 09 Sep '07

09 Sep '07

Ok, here's one for the idiot file. I just installed dovecot-1.0.4 on my personal system for testing, a system which has to be the simplest dovecot configuration possible. deliver is barking about something with which version 1.0.3 has no problem. I looked over the wiki, googled, and see nothing wrong. The error: deliver(jjb): Sep 07 21:39:40 Fatal: Failed to create storage for 'jjb' with mail 'mbox:/HOME_DIRECTORY_USED_BUT_NOT_GIVEN_BY_USERDB/:INBOX=/var/mail/jjb' In dovecot.conf: userdb passwd { # [blocking=yes] - By default the lookups are done in the main dovecot-auth # process. This setting causes the lookups to be done in auth worker # processes. Useful with remote NSS lookups that may block. # NOTE: Be sure to use this setting with nss_ldap or users might get # logged in as each others! #args = args = blocking=yes } and mail_location = mbox:~/:INBOX=/var/mail/%u Clues generously accepted, Jack

[Dovecot] Two newbie problems
by Timothy Murphy 08 Sep '07

08 Sep '07

I've started running dovecot on my server under Fedora 7, to act as an IMAPS server for kmail. 1. I see my email fine on my laptop in an IMAPS account, but it doesn't get updated - I mean I don't get any new email - until I run kmail on my server. This isn't a great problem, as I am always logged to the server with ssh, and I just start kmail and stop it after a few minutes. Then I run kmail on my laptop, and the new mail is there. But I assume this is not the intended system? 2. I opted (probably mistakenly) to set ~/Mail/inbox/ as my base IMAPS directory on my server. I'd like to change this to ~/Maildir (I use maildir folders). Is it relatively easy to do this? I tried copying my email to ~/Maildir/ and changing the setting in /etc/dovecot.conf (and restarting dovecot), but for some reason I could not see the email on my laptop. Any advice or suggestions gratefully received.

[Dovecot] o/s tuning for imap
by Ken A 07 Sep '07

07 Sep '07

I'm switching from a pop3 only dovecot install to a pop3/imap install and I'm wondering how many connections every 100 'normal' imap users might have/keep open? I'm wondering if I need to tweak any o/s related things, like time_wait, etc. Any pointers would be greatly appreciated. Thanks, Ken A.

See UserIds#mailusers for more information about different ways to allocate UIDs for users. All I want is to be able to access the mail, with the same my "virtual_uid_maps = static:501"(set in my postfix main.cf) All of these say it can be done, but how do I do it?

[Dovecot] Quota bug in deliver?
by FORMER 03 | Baltasar Cevc 06 Sep '07

06 Sep '07

Hi, I may be wrong, but I suspect a bug in dovecot deliver when using quotas. I've put some mails into a mailbox and then reduced the quota, to have the mailbox be over quota - here's the quota informaiton: [...] 2 getquotaroot INBOX * QUOTAROOT "INBOX" "" * QUOTA "" (STORAGE 880 5) 2 OK Getquotaroot completed. [...] When I have a setup with quotas only in the database, everything works as expected and deliver denies the message: Sep 5 21:50:14 ms4 deliver(postfach(a)email5.former03.local): msgid=<20070905195014.9D874239C007(a)ms4.srv.hoster03.de>: save failed to INBOX: Quota exceed ed Sep 5 21:50:14 ms4 deliver(postfach(a)email5.former03.local): msgid=<20070905195014.9D874239C007(a)ms4.srv.hoster03.de>: Rejected: Quota exceeded When I put a standard quota into the config as follows, the delivery succeeds (apparently deliver checks the standard quota, while IMAP correctly checks the quota from the database if it is returned.

[Dovecot] securing dovecot proxy connections
by bill-dovecot＠carpenter.ORG 06 Sep '07

06 Sep '07

The wiki <http://wiki.dovecot.org/PasswordDatabase/ExtraFields/Proxy> page says this: "The connections created to the destination server can't be TLS/SSL encrypted.". Hrmm. Right now, with perdition, I'm forcing the use of STARTTLS on the internal connections. I'd just as soon get rid of perdition (to have one less moving part in my architecture), but I need the secure connections. Is there a way to configure dovecot's internal proxy connections to use STARTTLS or some other SSL/TLS level of security? (Without a bunch more research, I don't know what the interaction is between the real client, the dovecot proxy, and the destination server.) -- bill-dovecot(a)carpenter.ORG (WJCarpenter) PGP 0x91865119 38 95 1B 69 C9 C6 3D 25 73 46 32 04 69 D6 ED F3

[Dovecot] How do I use sieve to move bounces?
by Jef Driesen 06 Sep '07

06 Sep '07

How can I use sieve to move bounces and non delivery reports (i.e. anything with an empty envelope from) to a special mailbox? I placed this snippet at the start of my sieve script require ["envelope", "fileinto"]; if envelope :is "from" "" { fileinto "INBOX.Reports"; stop; } But mails are not moved to the reports mailbox, and they are still processed by the rest of the script.

[Dovecot] OT Project idea: IMAP plugin for Google Desktop
by Kenneth Porter 06 Sep '07

06 Sep '07

Posting here, as Dovecot seems to be the premier IMAP server available. In case anyone is looking for something to work on, I found today that Google Desktop only understands email clients that keep mail on the client, and it would be nice if there was a plugin that understood IMAP. Here's a site that seems to explain how to write such plugins: <http://www.plugindevelopment.com/>

[Dovecot] alert function (possible WIBNI)
by Stewart Dean 05 Sep '07

05 Sep '07

The imapd spec has a provision for an alert pop-up of any ASCII text message contained in /etc/imapd.alert on the IMAP server. Can I assume this is implemented on DC? It'd be real nice if in addition to the current all-users message, it was possible to do a per-user alert...but I guess that would be something for IMAP standards....... -- ==== Stewart Dean, Unix System Admin, Henderson Computer Resources Center of Bard College, Annandale-on-Hudson, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035

[Dovecot] Dovecot + Sieve
by Marcin M. Jessa 04 Sep '07

04 Sep '07

Hi guys. I installed dovecot 1.0.3 with sieve plugin. It looks like sieve is loaded fine by dovecot [1]. I set up dovecot to use sieve globally: protocol lda { mail_plugins = cmusieve quota sieve_global_dir = /usr/local/etc/sieve/Junk ..... } And created a sieve file which is supposed to move all the Spam marked by dspam to users's Junk folder (listed as Junk in the subscriptions file) : require ["fileinto"]; # Move spam to Junk folder if header :contains ["X-DSPAM-Result:"] "Spam" { fileinto "Junk"; # Stop here so that we do not reply on spams stop; } I also set up postfix to use pipe mail through dovecot: mailbox_command = /usr/local/libexec/dovecot/deliver The problem is dovecot seems to be ignoring my sieve rule and delivers emails directly to INBOX. Any idea how to fix that?

[Dovecot] rule of thumb for indexing overhead
by bill-dovecot＠carpenter.ORG 30 Aug '07

30 Aug '07

I realize it's hard to be precise about this, but does anyone have a feel or rule of thumb for a couple of aspects of indexing overhead? 1. Proportionally, how much space does it take for all 4 files? If I want to give my users a quota of 100 MB for messages, how much real space should I plan for so that I won't run out of space for indexing? 2. What's the overhead in rebuilding index files? Suppose I use an LDA other than dovecot, so at least the INBOX index is frequently getting out of date. Does it cost much (in CPU, memory, and disk IO) to rebuild the index files? (I'm using maildir.)

[Dovecot] (slightly OT) syncing / migrating IMAP mailboxes
by Gunter Ohrner 28 Aug '07

28 Aug '07

Hi! I fear this may be slightly off-topic but it's both related to IMAP and to dovecot: Is there any good and in paticular realiable program for synching / migrating one IMAP mailbox to another? The most important features for me is that a) no mails are lost / left out silently and b) the porgram is able to sync the complete mailbox including all folders without just giving up in the middle of the transfer. If it's somehow possible, I'd like to migrate directly from one IMAP account to the other, without running the synchronizer on one of the servers and without accessing one of the Maildirs directly. I simply want to migrate my existing IMAP account from one Dovecot server (running 1.0beta5) to a new one (running 1.0rc15, as that's the version in Debian stable). Actually, a large part of the mailbox including most / all folders is already present on both servers, but I recently noticed that a few thousand mails are still missing. The current mailbox state is the result of two earlier (obviously incomplete :-( ) migrations a few months ago, from the original Dovecot 1.0beta5 server to a Cyrus server, and - shortly thereafter - from there on to the currently used Dovecot 1.0rc15. So far I've tried offlineimap, imapsync and mailsync, none of which seems to be really usuable. :-( The current state with the incomplete mailbox was caused by mailsync. When I did the first two migrations, mailsync looked like the only program which worked, but seems to have "forgotten" the missing messages. Another extremely suspicious thing is that mailsync reports "phantom changes" if run again immediately after synching a folder and will start to delete and copy / "sync" dozends of messages even if none of the folders actually changed after synching. I've read the name "imapsync" on this list several times, but I just tried it and just tried version 1.219. It happily starts synching the mailboxes and copying messages, but stops after partially synching the first folder - it simply exists, leaving no informational or error message whatsoever... Restarting imapsync will not help, it will appear to start synching the first folder again, but silently exit without doing anything. Some of you seem to use imapsync as a migration tool for production systems, how do you cope with these situations and how do you ensure a mailboxs' migration actually completed successfully? As you're probably not playing Roulette with your customers' or companie's eMails, I'm interested in your receipts to successfully use imapsync myself. As the third application I tried offlineimap (4.0.x-branch). During the migration a few months ago offlineimap (4.0.16 IIRC, synching from a Maildir to a remote IMAP account) was unusuable as it continuously and reproducibly threw exceptions at me during syncing obviously caused by specific messages in the accounts. Unfortunately, I wasn't able ti get any successful help on the offlineimap mailing list this time. :-( Now, synching from one IMAP account to another, specifiying the new server as the "local" account, offlineimap did not throw exceptions caused by mail messages so far, but it's performance is unusuable. It seems to use the "local" IMAP account on my target sevrer in a way which causes Dovecot to utilize all CPU power, copying one message every 10 to 20 seconds - this way, a sync would take ages and frequently aborts because of connection problems. The target server is an Athlon64 3700+ machine... So, does anyone have any pratical solution on how to migrate one IMAP mailbox to another? For various reasons I'd really prefer to go with a tested and working, reliable solution instead of starting to debug complex non-working programs I do not halfway understand and for which I cannot seem to get reliably support from its authors and/or its user community... :-/ Thanks a lot in advance for any pointers to a solution, Gunter -- +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ "The obvious mathematical breakthrough would be development of an easy way to factor large prime numbers." -- Bill Gates from The Road Ahead, p265 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ + PGP-verschlüsselte Mails bevorzugt! + +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+

[Dovecot] Some customers receiving duplicate e-mails
by Patrick - South Valley Internet 28 Aug '07

28 Aug '07

Hi all, I posted this question in the Postfix users mailing list as well - I'm not sure if this is Dovecot or Postfix related. Our old system which we migrated off of was an AIX 5.2 machine running most recent Postfix and mbox format with UW-IMAP. We've migrated to most recent Postfix, using Maildir and Dovecot v1. After we used mb2md to migrate over all our customers, some of our customers have called in to let us know they are receiving duplicate e-mails. It's not happening to everyone, it's random (well, I'm sure it's not really random, I haven't found the issue yet). I don't even know where to start. I looked at the logs, but everything looks fine. How can I troubleshoot something like this? Have any of you experienced the same issue? Thanks in advance.

[Dovecot] MANAGESIEVE patch v7 for dovecot 1.0.3
by Stephan Bosch 27 Aug '07

27 Aug '07

Hello dovecot users, I have updated the MANAGESIEVE patch to fix a recently reported problem. This is a patch against the latest stable release 1.0.3. It currently won't compile with 1.1 due to significant changes in the master code. Change Log V7 ------------- - Robin Breathe indicated that the regex capability was missing in the server's SIEVE listing. It turns out I forgot to make arrangements for setting ENABLE_REGEX in the cmu libsieve sources, so the regex extension was not compiled in. I copied the configure.in section regarding ENABLE_REGEX from dovecot-sieve-1.0.2 and that fixed the problem. This patch still includes (yet another) instance of the CMU Sieve source, as explained in one of my previous e-mails (http://dovecot.org/list/dovecot/2006-July/015016.html) The patch can be downloaded at: http://sinas.rename-it.nl/~sirius/dovecot-1.0.3-MANAGESIEVE-v7.diff.gz The README.managesieve is located in the root of the dovecot source tree after applying the patch. Have fun testing the patch. Don't hesitate to notify me when there are problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl IRC: Freenode, #dovecot, S[r]us

[Dovecot] Restoring a deleted/moved imap folder
by Oliver Schulze L. 27 Aug '07

27 Aug '07

Hi, one user of my imap server just deleted a whole folder, blame thunderbird I have the server disk and running Stellar Info for deleted files recovery. My cuestion is about how dovecot deleted an imap Maildir folder? The imap client is configured to move the deleted mails to the Trash folder, so I think dovecot would delete every Maildir email after successfully moved it. In the case a folder is deleted, is something special dovecot does to the email? Or it just run the unlink() function? In the case of compacting a folder, I think thats just a client side action. Many thanks Oliver -- Oliver Schulze L. | http://tinymailto.com/oliver Asuncion - Paraguay | http://www.solojuegos.mobi

[Dovecot] authentication with mysql - problem with table name escaping
by XhE 26 Aug '07

26 Aug '07

Found a problem with dovecot 1.0.3 and mysql authentication I got a problem with escaping of mysql table names. Usually, when a mysql table name has some special character (in my case there is a table beginning with the # character) one has to put into these special quotes --- ` ---; others like ' oder " are not recognized. But dovecot somehow doesn't allow me to do that. After switchting auth_verbose to true I get entries in /var/log/messages stating: Password query failed: Incorrect table name ' ' Regards, XhE

Trying to do a little (cosmetic) tweak to my configuration and just don't seem to be able to come up with a set of options that works. My POP/IMAP configuration is working just fine in terms of mail retrieval, etc. What I'm seeing in the logs now is... Aug 13 18:15:17 test2 dovecot: pop3-login: Login: user=<support>, method=PLAIN, rip=10.11.12.12, lip=10.11.12.13 I would prefer (for ease of troubleshooting) to have "user=<support(a)realm.com>" appear in the logs instead, to save having to figure the realm from the IP value. Have played around with various combinations of %u, %n and %d and all I seem to be able to accomplish is break the working part of the config. I'm sure the answer is probably something simple, or some combination I haven't tried... but it's certainly escaping me at the moment. The relevant (I think) part of my config follows. The usernames in the mentioned passwd and shadow files are in the 'user' format (ie. not 'user@realm'). --snip-- mail_location = mbox:/vhome/%l/home/%n/mail:INBOX=/var/spool/vmail/%l/%n auth_username_format = %n passdb passwd-file { args = /etc/vmail/shadow.%l } userdb passwd-file { args = /etc/vmail/passwd.%l } login_log_format_elements = user=<%u> method=%m rip=%r lip=%l %c --snip-- Hints and suggestions appreciated!

[Dovecot] removing IMAP keywords?
by martin f krafft 25 Aug '07

25 Aug '07

Hi there, I found that with an IMAP command like <unique-leader> STORE 1 +FLAGS (testflag) I can set arbitrary flags on mails through the dovecot IMAP daemon. This rules. Now I wonder, however, how I can remove those flags, which become properties of the folder, really. For instance, after the above, SELECT on the containing folder gives: * FLAGS (\Answered \Flagged \Deleted \Seen \Draft testflag) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft testflag \*)] Flags permitted. Even if I remove the flag from all messages or even delete all messages in the folder, the flag stays on the folder. Is there an IMAP way of removing flags from a folder? Also, does someone know where I can find specification on what characters are allowed for keywords? RFC 3501 is strangely quiet on this, or I am blind.

[Dovecot] [PATCH] Deliver doesn't enforce userdb quotas
by Sergio Lopez 24 Aug '07

24 Aug '07

Hello all, While configuring the latest stable version of Dovecot (1.0.3), I've noticed that "deliver" always uses the quota arguments found in the configuration file, completely ignoring what userdb sends to it through the authentication service. This doesn't happen in the previous version I was used (1.0.rc15, comes with Debian "etch"). After digging a little into the code, I've found that "expand_envs" is being called after "auth_client_put_user_env", thus clobbering the "QUOTA" environment variable. The attached patch changes "expand_envs" to avoid setting "QUOTA" if it has been exported before. Thanks! -- Sergio López - <sergio.lopez(a)nologin.es> Nologin Consulting S.L. - http://nologin.es

[Dovecot] Dovecot on different server than MTA
by FORMER 03 | Baltasar Cevc 24 Aug '07

24 Aug '07

Hi, I'm setting up our new mail system using dovecot as mailbox server. As our goal is to have many many small redundant (virtual) servers as components, for example a mailhub (just relaying mail) and a frontend smtp server (just accepting or denying mail in the first place and then forwarding it to the mailhub), etc. I want to run Dovecot on a different server than the main MTAs. The mailbox server is the only service that cannot be made redundant in an easy way (the servers don't have common storage and we can't add that easily), thus I prefer not to have it on the same server as the relay. Is there a best practice to do that? My current ideas are either to implement a stripped-down Postfix in the Dovecot server or to use some qpsmtpd setup there, both just to call the Dovecot delivery program. SMTP will be the communication protocol for the components except dovecot. (e.g. the virus scanner will be implemented as SMTP proxy). I'm quite bad at ASCII art, but I'll try anyways to illustrate the setup: I <--> [public incoming MX] -------------\ N | T \|/ E <--> [customer mailrelay] -----> [Postfix Mailhub] <====> virusscanner R | | N <-------outgoing mails-------------/ | E | T <--> [dovecot mailstore] <-mail delivery Each of the subsystems will be on a different virtual server in order to have small systems with distinct functions and to improve scalability. Everything except the dovecot server is planned to be duplicated on two different hardware machines (e.g. mx-in1 on server1, mx-in2 on server 2, mailhub1 on server1, mailhub2 on server2, virusscanner on server 2 and 3, etc. or something similar).

[Dovecot] Log Message Disconnected: Disconnected
by Jackie Hunt 24 Aug '07

24 Aug '07

We just started running Dovecot this summer at our campus. Overall things have gone very well, and performance have improved since moving off of U of Wash. We have run into an issue with a user running Thunderbird 2.0.0.6 on Solaris. He is seeing a very long response time (20mins+) on his first mailbox selection each morning when he comes into work. I looked at the Dovecot log, and the only think I can see that might be a bit out of the ordinary is two Disconnected messages that happen about 30 minutes apart each morning: Aug 17 04:54:08 host dovecot: IMAP(uname): Disconnected: Disconnected Aug 17 05:24:09 host dovecot: IMAP(uname): Disconnected: Disconnected The disconnected messages for other users say "Disconnected: Logged Out". I don't know for sure if these messages are related to his problem. Can anyone can shed some light on why Dovecot might indicate a "double disconnect"?

[Dovecot] Enabling IMAP namespaces for existing folders
by Phil Edwards 24 Aug '07

24 Aug '07

Hi. We're using dovecot 1.0.3 with a very very simple setup; specifically, there are no namespaces defined. Users have been puttering away happily for many months, creating subfolders and whatnot with (almost) zero problems. We'd like to start taking advantage of shared IMAP folders. I've been reading over the dovecot wiki and have only one question that I don't see documented. The docs point out that if we define any namespaces, we must also explicitly define the private previously-default one. My question is: are there any migration or transition steps that must be taken there? Will clients' configuration need to be modified in any way when, e.g., their existing IMAP folders suddenly become part of a private namespace? Thanks for the newbie help. -- Phil Edwards

[Dovecot] Imap service and quota
by Miguel 23 Aug '07

23 Aug '07

Hi, i have just migrated from courier-imap to dovecot. im using it with vpopmail, the pop service is working ok but the imap service for imp webmail is not writing the quota information to the maildirsize file, as recommended in the docs, i have this in dovecot.conf : plugin { # Quota plugin. Multiple backends are supported: # dirsize: Find and sum all the files found from mail directory. # Extremely SLOW with Maildir. It'll eat your CPU and disk I/O. # dict: Keep quota stored in dictionary (eg. SQL) # maildir: Maildir++ quota # fs: Read-only support for filesystem quota quota = maildir } This only happend with imp/imap, there is not problem using a pop client Regards,

[Dovecot] UW-IMAP to Dovecot conversion - How to migrate the folders?
by Patrick - South Valley Internet 23 Aug '07

23 Aug '07

Hi all, I've read so much information on this that I'm a little confused as to what to follow. Here's what's going on: We just migrated away from our AIX machines which were running Postfix and UW-IMAP. We're now running Postfix with Dovecot. I already converted everyone's mbox file to maildir, but now I'm having a little troubles with how to exactly populate their IMAP folders. People are saying they cannot see their folders. These 'folders' they are talking about can be found in their /home directory. I have the following URLs I've been looking at: http://wiki.dovecot.org/Migration/MailFormat http://people.redhat.com/rkeech/maildir-migration.txt http://wiki.dovecot.org/Plugins/Convert http://www.dovecot.org/list/dovecot/2007-June/023757.html What would be the suggested method to convert them? So far I understand that I need to somehow populate the /home/USERNAME/Maildir/subscriptions file with the items located in /home/USERNAME/.mailboxlist and then I don't know what to do from there. I don't know if I need to incorporate a Dovecot plugin, or if there is a script I can run to do this for me. Since this is a live server, I would prefer to test on a single account before I run a plugin that would effect all users globally. Any help would be very appreciated - thanks in advance! Patrick

[Dovecot] Exim-dovecot-Horde/imp-Mysql
by Andre Eisvogel 22 Aug '07

22 Aug '07

Dear all, I'm running a linuxbox with ' Dovecot<->Exim<->horde/IMP<-> Mysql ', this is a very good combination and works excellent for the system users. Now I want to change the configuration and authenticate against the mysql database from horde. That way it is much easy for me to create (virtual) mail users. I also want to use the mail alias of the horde users for Exim and Dovecot. My questions are; is it possible to use the horde mysql database for this? And is it also possible for the mail alias of horde? If this is possible, is there a howto of this configuration? The packages i'm using are: Exim 4.67 Dovecot 1:1.0.3 Horde 3.1.4 Mysql 5.0.45 PHP 5.2.3 -- Met vriendelijke groet / Kind regards, André Eisvogel

[Dovecot] maildir question
by Tim Bates 22 Aug '07

22 Aug '07

If I copy message files (from a command prompt) will dovecot get upset or confused? Do I need to delete index files or anything like that? I ask because I need to restore some messages from a backup, but not restore the entire maildir. I tried some the other day as a test, but the user is saying that they didn't appear.

[Dovecot] Subscriptions - delivering to different folders
by bichumo 21 Aug '07

21 Aug '07

Hi, I am using Postfix and Dovecot. I have set up backup_mailbox(a)domain.tld, which gets mail copies from user1(a)domain.tld user2(a)domain.tld user3(a)domain.tld, the copy option is set in postfix recipient_bcc_maps = path_to_file_recipient_bcc. In recipient_bcc file I have: user1(a)domain.tld backup_mailbox(a)domain.tld user2(a)domain.tld backup_mailbox(a)domain.tld user3(a)domain.tld backup_mailbox(a)domain.tld Postfix does the job and copies user1, user2, user3 emails to backup_mailbox. But I also want to filter mails in backup_mailbox and to put user1 mails to USER1 folder in backup_mailbox, user2 mails to USER2 folder in backup_mailbox and so on. How this is possible? I made an entry in subscriptions file of user1, user2, user3. Now I have folders .user1, .user2, user3 in backup_mailbox folder and I can also see these folders through webmail client (squirrelmail), but how do I put email copy which comes from user1(a)domain.tld to backup_mailbox(a)domain.tld to go not to main folder of backup_mailbox but to USER1 folder in backup_mailbox folder. Thanks for any suggestions.

It's then accessed only when and where needed. It probably does access the whole file though. This is because all the cached data for messages are stored next to each others. So now that your client fetches only INTERNALDATE it doesn't really need to read much, but because mmaped pages are read 4kB at a time, it practically reads the whole file. Perhaps this could use some work in future too, so that fields that are accessed together are stored in cache file close together. But then if multiple clients are used, there can be conflicting access patterns, and what's good for one client would be bad for another. Data could also be duplicated to reduce disk reads for different access patterns, but that comes at the cost of disk space..

[Dovecot] Dovecot fails almost every 20 minutes exactly
by Patrick - South Valley Internet 21 Aug '07

21 Aug '07

Hi all, We just set up our new mail servers using Postfix and Dovecot. We have implemented a load balanced solution to where our two mail servers have a common NFS share. Everything is working great. Everything but Dovecot for the most part. In testing, Dovecot was great. Now that we're in the production environment, we've noticed that every 20 minutes, Dovecot will stop running. But it gets even weirder - it appears that Machine A will stop, then 20 mins later after we issue a 'service dovecot restart', Machine B will stop. Then the whole process starts over when we restart Dovecot on Machine B. I can't see anything out of the ordinary in the log files either. I'm at a loss as to what's going on. Here's my dovecot -n: ################################ # 1.0.3: /etc/dovecot.conf listen: * ssl_cert_file: /usr/share/ssl/hermes.garlic.com/hermes.garlic.com.cert.pem ssl_key_file: /usr/share/ssl/hermes.garlic.com/hermes.garlic.com.privatekey.pem login_dir: /var/run/dovecot-login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login first_valid_uid: 200 mail_location: maildir:/home/%u/Maildir:INDEX=MEMORY maildir_copy_with_hardlinks: yes maildir_copy_preserve_filename: yes mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 auth default: user: dovecot-auth username_format: %Lu passdb: driver: pam userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix ################################ Any ideas what could be wrong?

[Dovecot] Dovecot IDLE bandwidth usage
by Fredrik Tolf 20 Aug '07

20 Aug '07

Hi list, I just recently discovered the IMAP IDLE command and tried it out with my Dovecot server. It seems to work fine and all, but it seems to be using quite a deal of bandwidth, because of the "* OK Still here" messages sent by the server at two minute intervals. I would argue that is a bit of a problem when using the IDLE command for "Push mail" on a mobile phone. I don't know exactly what parts of the packets that mobile carriers collect payment for, but the Ethernet bandwidth consumed by one such message is 149 bytes (83 bytes for the message itself, and 66 bytes for the TCP ACK from the client). At two minute intervals, that becomes over 100 KB per day, and over 3 MB per month. At GRPS rates typical here in Sweden, that becomes about 5-7 USD per month. That might not seem tremendously much, but seeing how it is what takes up the vast majority of the IMAP bandwidth, it is still quite annoying. Are those messages really necessary? I mean, Dovecot still times out after half an hour if the client doesn't "finish" the IDLE command and re-issues it, right? (Coincidentally, I would like to argue that it would be better not to time out at all during an IDLE command and just turn on TCP keepalives instead, but that is the minor issue here) I'll apologize in advance if this is already a tunable option, but I haven't found anything about it in the configuration file. Cheers, Fredrik Tolf

[Dovecot] MANAGESIEVE patch v6 for dovecot 1.0.3
by Stephan Bosch 18 Aug '07

18 Aug '07

Hello dovecot users, I have updated the MANAGESIEVE patch to (hopefully) fix the compilation issues reported by Robin Breathe. This is a patch against the latest stable release 1.0.3. It currently won't compile with 1.1 due to significant changes in the master code. Change Log V6 ------------- - Corked the client output stream while producing the capability greeting and on other some other occasions as well. Some naive client implementations expect to receive this as a single tcp frame and it is a good practice to do so anyway. Using this change the Thunderbird sieve extension (v0.1.1) seemed to work. However, scripts larger than a tcp frame still caused failures. All these issues are fixed in the latest version of the sieve add-on (currently v0.1.4). - Cleaned up the new proxy source. My editor made the indentation a complete mess in terms of TABs vs spaces. - Added TRYLATER response codes to BYE and NO messages where appropriate. - Recopied the libsieve library into this patch to incorporate any changes that were made (only sieve-cmu.c still needs to be compared to the old cmu-sieve.c). This also solves the __attribute__((unused)) GCC dependencies. These were fixed long ago by Timo.... the code duplication beast strikes again. (Will have to do this again for dovecot 1.1) - Removed spurious return value from void function in src/lib-sieve/sieve-implementation.c as reported by Robin Breathe. GCC fails to report these issues. The function involved is currently not used and serves only as an example on how dovecot could support multiple sieve back-ends... This patch still includes (yet another) instance of the CMU Sieve source, as explained in one of my previous e-mails (http://dovecot.org/list/dovecot/2006-July/015016.html) The patch can be downloaded at: http://sinas.rename-it.nl/~sirius/dovecot-1.0.3-MANAGESIEVE-v6.diff.gz The README.managesieve is located in the root of the dovecot source tree after applying the patch. Have fun testing the patch. Don't hesitate to notify me when there are problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl IRC: Freenode, #dovecot, S[r]us

[Dovecot] Migrating from imapd to dovecot - how to keep user's Mail folders
by Patrick - South Valley Internet 17 Aug '07

17 Aug '07

Hi all, We're migrating off our current mail server with runs postfix and imapd on an AIX machine to Postfix and Dovecot running linux. Our customers have a lot of IMAP folders with folders they configured, which are currently located in their /home directory on the current mail server. The new mail server will have them at the same location. How do I configure Dovecot so that when a customer connects via IMAP using their favorite e-mail client, that the folders will be there? Thanks in advance. Patrick

[Dovecot] Dovecot 1.0.3: LDA + quota plugin

[Dovecot] High CPU utilization on Solaris 10

[Dovecot] dovecot notifying a database about total number of messages.
by Erland Nylend 17 Aug '07

17 Aug '07

Hello, in addition to our mail system, we have some other systems which needs to know how many messages, and how many unread messages, a user has in his/her inbox (maildir). Currently, we have a mod_perl script which takes a mail address as input, and then traverses the maildir, and outputs the number of unread messages. Our challenge is that the maildirs are located on a SAN, and traversing a maildir is slow. We currently have more than 100 requests pr. second, which we handle with caching, and spreading the load across different servers. I'm looking into the possibility of either using dovecots index files, or having dovecot update a database with total number of messages/number of unread messages. Question: 1) if I'm using perl, is there any way I can read in the information in the index files? Is the data formatted in some standarized way, so that I can parse it, or use a module which read in the data? (if I can read the indexes in wrapper scripts to imap/pop/deliver, then I could probably update a database with the information) 2) how would you proceed, if the aim is to end up with dovecot notifying a database regarding the number of messages, and unread messages? -- Erland Nylend

[Dovecot] ssh tunneling and maildir
by Joel Becker 17 Aug '07

17 Aug '07

Hello everyone, please keep my CC'd, I'm not on the list. I've been using dovecot happily via an ssh tunnel. My mutt is configured to use IMAP, and the tunnel is as follows in my muttrc: set tunnel="ssh -q mymailhost 'MBOX_LOCKS=fcntl MAIL=/home/jlbec/mail /usr/libexec/dovecot/imap'" It should be pretty obvious that this logs into mymailhost as me (via SSH keyauth) and runs /usr/libexec/dovecot/imap directly as a foreground process. Setting MAIL, it points dovecot imap to my mbox folders. dovecot imap speaks imap over stdin/out, this goes over the ssh to mutt. It works great. Really great. I don't need root access at all, the server isn't running dovecot globally, and I get IMAP through firewalls if I can ssh through a firewall/vpn. I'm using mbox and fcntl, so my MTA has no trouble working in concert. However, this doesn't appear to be documented anywhere. A friend showed it to me, and I don't even remember who that was. I'm now considering changing to maildir folders. I figure dovecot imap might figure out a folder is maildir when stat says S_IFDIR, but without documentation, I can't figure out how to tell dovecot imap to use maildir when I create a folder. I'm also unsure how this will interact with my MTA. For the latter, I'm thinking I just need to configure my MTA to use dovecot's deliver program. For the former, is there some magic environment variable I need to add to my tunnel command line?

[Dovecot] Recover mailboxes
by Jordi Espasa Clofent 17 Aug '07

17 Aug '07

HI all, Some time ago I've user(a)domain.com in maildir mailbox with their own mails, their folders, subfolders, indexes files.. etc My server was missconfigured and I've rebuilded all SMTP; I've recreated all the mailboxes with same names that before. Of course, the problem is the content of these mailboxes it's not the same. So, the idea is: add all the contento from user(a)domain.com (old) mailbox to user(a)domain.com (new) mailbox. because I have got a complete copy of (old) mailboxes and their content. ¿How can I do it?

[Dovecot] High CPU utilization on Solaris 10

Some people had this problem when giving some superoptimization flags with Sun Studio. Did you do that? -Timo No I did not use any optimization. And Dave, I took what you said and just tried both dovecot-1.0.2 dovecot-1.0.rc29 and have the same exact results :(

[Dovecot] index and control files not being created
by Luis Pablo Michelena Scaffo 16 Aug '07

16 Aug '07

Hello, I'm configurating dovecot 1.0.3 on debian etch. While trying to set public folders, y decided to have the index and control files on the users homes. those homes are mounted by nfs, with disabled access to root. In that scenario, I'm getting the errors i transcribe next: Aug 16 11:21:17 server dovecot: IMAP(user): fchown(/home/user/Maildir/shared-settings/control/.folder/dovecot-uidlis t) failed: Operation not permitted Aug 16 11:21:17 server dovecot: IMAP(user): fchown(/home/user/Maildir/shared-settings/control/.folder/dovecot-uidlis t) failed: Operation not permitted Aug 16 11:21:17 server dovecot: IMAP(user): rename(/inbox/shared/.folder/cur/mailfile, /inbox/shared/.folder/cur/mailfile :2,S) failed: Operation not permitted Aug 16 11:21:17 server dovecot: IMAP(user): fchown(/home/user/Maildir/shared-settings/control/.folder/dovecot-uidlis t) failed: Operation not permitted Aug 16 11:21:17 server dovecot: IMAP(user): rename(/inbox/shared/.folder/cur/mailfile, /inbox/shared/.folder/cur/mailfile :2,S) failed: Operation not permitted Aug 16 11:21:26 server dovecot: IMAP(user): Disconnected: Logged out Aug 16 11:21:27 server dovecot: IMAP(user): fchown(/home/user/Maildir/shared-settings/control/.folder/dovecot-uidlis t) failed: Operation not permitted Aug 16 11:21:27 server dovecot: IMAP(user): rename(/inbox/shared/.folder/cur/mailfile, /inbox/shared/.folder/cur/mailfile :2,S) failed: Operation not permitted Then I touched those files and the errors faded away. Beside that, I was testing the setup, and while trying to delete some files on the shared folder, I got another error: Aug 16 16:38:04 server dovecot: IMAP(user): rename(/inbox/shared/.folder/cur/1183976419.755_0.server:2,Sa, /inbox/shared/.folder/cur/1183976419.755_0.server:2,STa) failed: Operation not permitted Aug 16 16:38:11 server dovecot: IMAP(user): fchown(/home/user/Maildir/shared-settings/control/.folder/dovecot-uidlist) failed: Operation not permitted Aug 16 16:38:11 server dovecot: IMAP(user): rename(/inbox/shared/.folder/cur/1183976419.755_0.server:2,Sa, /inbox/shared/.folder/cur/1183976419.755_0.server:2,STa) failed: Operation not permitted Which seems odd, because I though that as a flag, the deleted flag should be marked on the index files and not directly on the shared folder (where the user hasn't any permission other than reading), ant the same goes to the "read" flag Am I wrong? Is there any workaround to make dovecot behave the way I'd liked? The config follows: login_executable: /usr/lib/dovecot/imap-login mail_extra_groups: mail mail_location: maildir:/home/%u/Maildir:INBOX=/inbox/mdir/%u mmap_disable: yes namespace: type: private separator: / location: maildir:~/Maildir:INBOX=/inbox/mdir/%u inbox: yes namespace: type: public separator: / prefix: Shared folders/ location: maildir:/inbox/shared:INDEX=/home/%u/Maildir/shared-settings/index:CONTROL=/home/%u/Maildir/shared-settings/control auth default: passdb: driver: passwd args: blocking=yes passdb: driver: shadow userdb: driver: passwd Cheers, Luis

[Dovecot] ANY password option
by Master Abi 16 Aug '07

16 Aug '07

Hi We sometimes migrate mailboxes over to one of our mail servers which has a very handy feature called 'ANY password'. This will allow access to a mailbox using the given username and disregard checking for the password. This is a useful feature for many reasons. Is there a possibility Dovecot could have such a a feature or is there a workaround already. Thanks Master

[Dovecot] Moving a mail between folders and post-processing ?
by Jerry Nicholls 16 Aug '07

16 Aug '07

Hi, Within Dovecot is there a way of spotting a change to a folder and running a post-processing script on the email that was moved ? I'm specifically after a way of seeing either an email entering or leaving a folder - preferably running a different post-process script depending on the direction. Essentially if an email enters or is moved out of a 'spam' folder I'd like to mark it as 'spam'/'ham' in the Bayesian filters respectively. Is there any such mechanism, or should I start looking at how to write a plugin to achieve this ? If it's the plugin route is there any good documentation on the plugin APIs etc ? Thanks, Jerry. -- Jerry Nicholls E: Jerry.Nicholls(a)zeninternet.co.uk Core Systems & Networks Manager W: http://www.zen.co.uk/ Zen Internet Ltd. T: 0845 058 9000 F: 0845 058 9005

[Dovecot] MANAGESIEVE patch v5 for dovecot 1.0.2
by Stephan Bosch 15 Aug '07

15 Aug '07

Hello dovecot users, I have finally updated the MANAGESIEVE patch to fix the currently known small problems with the protocol implementation. Also, I included a proxy implementation based on imap-proxy.c. This patch is designed for dovecot release 1.0.2 and it will not apply cleanly to the 1.1 versions yet. Change Log V5 ------------- - Applied patch by Uldis Pakuls to fix master_dump_settings bug - Added some compilation/installation info to the README - Moved README to source tree's root as README.managesieve - Fixed minor error handling bug in sieve_storage.c with respect to a missing root directory. - Now sieve capabilities are reported as they are specified by the implementing library and not in forced upper case. The sieve RFC now explicitly states that sieve capability identifiers are case-sensitive. This broke compatibility with SquirrelMail/Avelsieve. - Disabled ANONYMOUS login entirely until proper support is implemented. V4 claimed to do so as well, but in fact it only stopped announcing it. - Implemented managesieve-proxy. It is not so much a clean copy of imap-proxy, since the managesieve greeting is much more complex and requires parsing. Configuration is identical to imap-proxy. This seems to be a little under-documented however (http://wiki.dovecot.org/PasswordDatabase/ExtraFields) This patch still includes (yet another) instance of the CMU Sieve source, as explained in one of my previous e-mails (http://dovecot.org/list/dovecot/2006-July/015016.html) Current plans include merging src/lib-managesieve with src/lib-imap, updating the patch for dovecot-1.1 and fixing any problems you might find. The patch can be downloaded at: http://sinas.rename-it.nl/~sirius/dovecot-1.0.2-MANAGESIEVE-v5.diff.gz The README.managesieve is located in the root of the dovecot source tree after applying the patch. Have fun testing the patch. Notify me when there are problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl IRC: Freenode, #dovecot, S[r]us

[Dovecot] Dovecot deliver + sieve + postfix virtual + mysql ?

Hey there guys. I have successful postfix + mysql + sagator + clamav + spamassassin + dovecot setup (it was a really crazy month full of tweaking :]) and the only thing i miss is some per maildir specific filtering. i decided to use sieve. everything is fine except that dovecot's deliver process doesn't see the actual .dovecot.sieve file with filtering rules in the root of a maildir. description of the situation follows: from /var/log/dovecot.log: deliver(support{the_at_symbol}support.etnetera.cz): "2007-08-15 13:32:11 "Error: userdb(support{the_at_symbol}support.etnetera.cz) didn't return a home directory or sieve script location, can't find it deliver(support{the_at_symbol}support.etnetera.cz): "2007-08-15 13:32:11 "Info: msgid=<200708151330.22021.radek.slavicinsky{the_at_symbol}etnetera.cz>: saved mail to INBOX /etc/dovecot/dovecot.conf: protocols = imap imaps pop3 pop3s listen = * disable_plaintext_auth = no shutdown_clients = yes log_path = /var/log/dovecot.log log_timestamp = "%Y-%m-%d %H:%M:%S " ssl_cert_file = /etc/certs/sponka.etnetera.cz.crt ssl_key_file = /etc/certs/sponka.etnetera.cz.key ssl_ca_file = /etc/certs/CA.crt login_process_size = 64 login_processes_count = 32 login_max_processes_count = 256 login_max_connections = 512 mail_location = maildir:/srv/vmail/domains/%d/%n/ #mail_location = maildir:/ namespace private { separator = . prefix = INBOX. inbox = yes } namespace private { separator = . prefix = inbox = yes hidden = yes } mail_extra_groups = vmail verbose_proctitle = yes mbox_read_locks = fcntl mbox_write_locks = fcntl protocol imap { } protocol pop3 { pop3_uidl_format = UID%u-%v } protocol lda { hostname = sponka.etnetera.cz postmaster_address = postmaster{the_at_symbol}etnetera.cz auth_socket_path = /var/run/dovecot/auth-master mail_plugins = cmusieve } auth default { mechanisms = plain login digest-md5 cram-md5 passdb sql { args = /etc/dovecot/dovecot-sql.conf } userdb sql { args = /etc/dovecot/dovecot-sql.conf } user = dovecot-auth socket listen { client { path = /var/spool/postfix/private/auth mode = 0666 user = postfix group = postfix } master { path = /var/run/dovecot/auth-master mode = 0600 user = vmail group = vmail } } } dict { } plugin { } /etc/dovecot/dovecot-sql.conf: driver = mysql default_pass_scheme = PLAIN connect = host=127.0.0.1 dbname=postfix user=postfix password=averysecretpass password_query = SELECT password FROM mailbox WHERE username = '%u' AND active = '1' user_query = SELECT maildir, 65500 AS uid, 65500 AS gid FROM mailbox WHERE username = '%u' AND active = '1' the user_query gives: mysql> SELECT maildir, 65500 AS uid, 65500 AS gid FROM mailbox WHERE username = 'radek.slavicinsky(a)etnetera.cz' AND active = '1'; +--------------------------------+-------+-------+ | maildir | uid | gid | +--------------------------------+-------+-------+ | etnetera.cz/radek.slavicinsky/ | 65500 | 65500 | +--------------------------------+-------+-------+ 1 row in set (0.00 sec) the sieve rules file # ls /srv/vmail/domains/support.etnetera.cz/support/.dovecot.sieve -lha -rw-r--r-- 1 vmail vmail 957 Aug 15 13:30 /srv/vmail/domains/support.etnetera.cz/support/.dovecot.sieve i think there should be some specific settings for the cmusieve plugin, but i didnt find much docs about that thx for any help ;] blue4 :p

[Dovecot] use of deliver from procmail advisable?
by martin f krafft 15 Aug '07

15 Aug '07

Hi list, I understand that dovecot's deliver does a little more than deliver: it also updates the dovecot metadata stored with each Maildir. Thus, if I use deliver as opposed to procmail's internal Maildir delivery, it seems that the IMAP server later has less work to do since the metadata is can use are up to date. Doing this, however, incurs an extra process for each mail delivered. I thus wonder whether the two balance each other out, or whether there is a strong difference. What do you think will be less resource-heavy: calling deliver for every mail received *in addition to* procmail, or letting the IMAP server update the metadata on access? -- martin; (greetings from the heart of the sun.) \____ echo mailto: !#^."<*>"|tr "<*> mailto:" net@madduck EARTH smog | bricks AIR -- mud -- FIRE soda water | tequila WATER spamtraps: madduck.bogus(a)madduck.net

[Dovecot] namespaces and creation of folders that contain folders...
by bhayden＠umn.edu 14 Aug '07

14 Aug '07

Hi Timo and all. imap/cmd-create.c contains the following bit of code: len = strlen(full_mailbox); if (len == 0 || full_mailbox[len-1] != ns->sep) directory = FALSE; else { /* name ends with hierarchy separator - client is just informing us that it wants to create children under this mailbox. */ directory = TRUE; mailbox = t_strndup(mailbox, len-1); full_mailbox = t_strndup(full_mailbox, strlen(full_mailbox)-1); i_info("Z CREATE NAME: YYY%sYYY", mailbox); } We've been having trouble with people not being able to create a mail folder that will contain other folders. Tried it both with users using mbox (where this would be a filesystem directory) and maildir. Failed everytime because of a test which rejects folder names that end with MAILDIR_FS_SEP. Looks like the above bit of code is supposed to catch these, make a note of the fact that the client wants a directory, and strip off that trailing separator. In fact, it does this in the case of 'full_mailbox'. However, for 'mailbox' (it seems to me) the code is incorrect as its using the len-1 which is the length of 'full_mailbox', not 'mailbox'. This means that when 'mailbox' and 'full_mailbox' are the same length--that is, for the default namespace (no prefix), it happens to work. However, in any other namespace, it won't, as 'full_mailbox' will always be longer then 'mailbox' if there is a ns prefix, and hence that trailing separator won't be trimmed. (As a matter of fact, in the unlikely instance that the prefix is a single character this will trim the null character from 'mailbox', which probably isn't a good thing.) So. Am I missing something, or crazy, or is this really a bug? Thanks, -Brian

Hi Timo, Is the dovecot index cache stored only standard header fields (from, to, cc, subject, content-type... )? What happen if there is non standard header, will it be cached? - Joe May the force be with you..

[Dovecot] status of APPENDUID: returning a UID in response to APPEND
by martin f krafft 14 Aug '07

14 Aug '07

# dovecot-related content below, this one for debian bug tracking # system: retitle 435959 Please support RFC4315 UIDPLUS extension in APPEND reply severity 435959 wishlist thanks [please keep 435959(a)bugs.debian.org on Cc.] Hi there, I am working on http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=435959, which is a performance problem that offlineimap has on large mailboxes. We think that a simple patch to dovecot could cure this problem. I am willing to write the patch but would really like to get your opinion first. In order to keep track of which IMAP message is stored in which local file, offlineimap uses the message UID, which is guaranteed to be unique in the directory, but constant across sessions. When uploading a new message to the IMAP server with APPEND, offlineimap then has to run a SEARCH to obtain said UID for the message it just uploaded. This takes ages on larger mailboxes, as the way offlineimap identifies the message is via a header that's not indexed by dovecot. The solution I found in RFC4315 ("UIDPLUS"; http://www1.tools.ietf.org/html/rfc4315) and then I saw http://www.dovecot.org/list/dovecot/2004-July/003993.html, and now I am wondering: is anyone else interested in APPENDUID? What's the status of an implementation, if any? Newer Courier IMAP server implementation support UIDPLUS and offlineimap will likely obtain this functionality soon.

I attach a patch that adds some informational logging for the vacation outcome in a similar style as the 'notify', 'redirect' and 'reject' cases. I considered adding logging for the not-willing-to-respond case since I think that would greatly assist testing/debugging vacation responses, but couldn't see where to put it that wasn't in the CMU code.

[Dovecot] plain authentication
by Roger D. Vargas 13 Aug '07

13 Aug '07

After upgrading my server I have found that Im not able to use plain auth for clients conecting from outside server. localhost clients (pine, webmail) works fine, but if I use Thunderbird I got an error saying that server requires TLS or SSL. But if I enable TLS or SSL I got more errors. I have tried sevral combinations, but havent found a working one. Here is my config, can somebody see what Im doing wrong? # /etc/dovecot/dovecot.conf protocols: imap pop3 ssl_disable: yes ssl_cert_file: /etc/ssl/dovecot/server.pem ssl_key_file: /etc/ssl/dovecot/server.key login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login login_greeting_capability(default): yes login_greeting_capability(imap): yes login_greeting_capability(pop3): no mail_extra_groups: mail mail_location: mbox:~/mail/:INBOX=/var/spool/mail/%u mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 auth default: passdb: driver: shadow userdb: driver: passwd -- Roger D.

[Dovecot] "pipe" plugin
by Nicolas Boullis 13 Aug '07

13 Aug '07

Hi, Long ago (more than 2 month ago), I told about a "pipe" plugin I had written to perform some spam/ham learning (see the attached message). I'm now proud to say that I can make it available for use by anyone. You can get it from http://nicolas.boullis.free.fr/pipe.tar.gz Note that this is a temporary location. If someone had a good place to host it, feel free to do (and tell). I think it would be great if the feature could be merged into dovecot. I don't care whether my plugin is used or a rewrite is performed... Cheers, Nicolas

[Dovecot] Inbox re-initialized
by Joshua, C.S. Chen 13 Aug '07

13 Aug '07

Hi folks, I just replaced my mail server's UW-imap with dovecot yesterday. I use the following folder setting default_mail_env = mbox:/asiaa/home/%u/:/asiaa/home/%u/mail/:INBOX=/var/mail/%u:INDEX=/asiaa/home/%u/mail/dovecot_indexes This is a Scientific linux 4.2 with dovecot 0.99.11-2 . Now today the server loading is highly reduced because of the pop3 session impact is low. But users have the following problems: For outlook express users, when they come in the office, the first time they launch outlook express, they found that the previous Inbox is re-transmitted. So they got double the number of all past e-mails (they setup OE setting to keep a copy on the server). And some users also use pine. After the pine session, they get another whole copy of the past e-mails (so some users got 3X or even 4X the past e-mails). Am I missing something for the dovecot.conf setting, here is the entire configurations: Thanks in advance protocols = pop3 pop3s imap_listen = [::] pop3_listen = [::] log_path = /var/log/dovecot login_dir = /var/run/dovecot-login login = imap login = pop3 default_mail_env = mbox:/asiaa/home/%u/:/asiaa/home/%u/mail/:INBOX=/var/m ail/%u:INDEX=/asiaa/home/%u/mail/dovecot_indexes mbox_locks = fcntl auth = default auth_mechanisms = plain auth_userdb = passwd auth_passdb = pam auth_user = root Cheers Joshua

[Dovecot] using complete email address as username
by WJCarpenter 13 Aug '07

13 Aug '07

I've been poking around the dovecot wiki, and this idea looks plausible. I'm just double-checking with the assembled experts to see if there is some "gotcha" that will happen to me down the road. I have in mind a deployment of dovecot which will use serve several unrelated domains. My plan is to use the complete email address of the users as the unique userid. So, for example, a user with email address <foo(a)example.COM> is unrelated to a user with email address <foo(a)example.NET>. The "home" directories of such users will look something like: /some/path/foo(a)example.com/ /some/path/foo(a)example.net/ I do also plan to use ACLs for some things, so there could be ACL entries of the form: user:foo@example.com ... I will probably be using the quota plugin for individual users right away and group quotas later when that's officially available. So, is all this likely to work or will it collapse in a miasma of unmet expectations? Thanks in advance for any comments!

[Dovecot] Deleting deleted eMails
by Michael Weisgerber 11 Aug '07

11 Aug '07

Hello 2gether, I am using Dovecot 1.0.rc15 together with Outlook (I apologize) via IMAPS. Now I discovered, that all the old eMails, I marked for deleting, are still there, even the veeery old ones. Dovecot is marking the eMails (I am using maildir configuration) files with an "ST" extension. Is there any switch to turn on garbage collection and maybe a screw to tune the duration until deletion? Thanks for your help! Michael Weisgerber

[Dovecot] dovecot: child 1690 (auth-worker) killed with signal 11
by Thomas Zajic 10 Aug '07

10 Aug '07

Hi there, I've been seeing this for quite a while now, but only today finally got off my lazy you-know-what and did a backtrace. Here's the requested info as per http://dovecot.org/bugreport.html: * Dovecot version [root@airframe]:~# dovecot --version 1.0.3 * Operating system or Linux distribution name Slackware 10.2, both kernel 2.6.21.3 and dovecot self-compiled * CPU architecture (x86 or something else?) x86 (AMD Athlon XP 3200+) * Filesystem you used (especially if you use NFS or not) ext3, local (no NFS) * Some kind of description of what you were doing and with what IMAP client. Thunderbird 2.0.0.4 (also happened with earlier versions) mail-notification-4.1 (" " " " " ) * If the problem can be reproduced, it helps a lot if you can tell how. Happens in almost regular intervals, not sure when exactly though. Usually when doing something in TB again (deleting or moving mails) after it has been sitting idling for a while.

[Dovecot] Version 1.1 Alpha 2 Various Stuff
by Jerry Yeager 09 Aug '07

09 Aug '07

Some preamble information… OS X 10.4.10 (all updates) Power Mac Dual G5, 2.0 Postfix with Dovecot SASL, Dovecot LDA, Dovecot imaps (openssl) Mail clients Apple Mail v 2.1 SquirrelMail v 1.4.10a Thunderbird v 2.0.0.6 Mulberry v 4.06 For various versions of Dovecot, from 0.9m up through 1.0.3 things went well, no memorable big problems, with one exception: Mulberry v 4.0.8 would/will not work; i.e. it refuse(d) to connect saying it could not start SSL to begin the connection. Dropped back to version 4.0.6. I switched to version 1.1 alpha 2 (compile and configuration information is attached at the end of this message) 1) Started up Apple mail. Mail boxes disappeared in Apple Mail's list, except for the main Inbox mail box. Fixed by setting mailbox_list_index_disable = yes in the Dovecot.conf file, restarted both Dovecot and Mail, all the mailboxes reappeared and worked correctly. 2) Started up Squirrel Mail using several different browsers. No problems. 3) Started up Thunderbird. No problems. 4) Started up Mulberry. It partially connected, but stopped with the error saying that it had hit the limit for maximum connections. Mail logs show: dovecot: imap-login: Maximum number of connections exceeded: user=<username>, method=PLAIN, rip=192.168.1.1, lip=192.168.1.50, TLS I tried increasing the various limits in the Dovecot.conf file up through a maximum limit of 2048 connections, to no avail. Mulberry will initially connect to several of the mailboxes, but will stop without getting all of them and will throw up the 'over the connection limit' error and will then show you a dialog box that asks you to log-in. Attempting to doing so returns a fatal error 54. I have not tried Mulberry's version 4.0.8. 5) Mail logs had this message suddenly begin appearing: auth-worker(default): pam(username,192.168.1.1): pam_authenticate() failed: Authentication failure Fixed by completely commenting PAM authentication section out; It was: passdb pam { # [blocking=yes] [session=yes] [setcred=yes] # [cache_key=<key>] [<service name>] # ... essentially a placeholder section, since everything inside is commented out # # } now is: #passdb pam { # # ... even the outer block is commented out # #} The error has now disappeared from the logs.

[Dovecot] Crash with 1.1alpha2 when lazy_expunge is enabled?

I'm seeing a crash in 1.1alpha2 when trying to expunge a folder when "lazy_expunge" is enabled: namespace private { separator = . prefix = .EXPUNGED/ location = maildir:/mailstore/%u/Expunged hidden = yes } ... lazy_expunge = .EXPUNGED/ .EXPUNGED/ .EXPUNGED/ Commenting out "lazy_expunge" prevents the crash and mail is expunged.

[Dovecot] UW-IMAP style mbox snarfing from /var/mail/ to ~/mbox
by Timo Sirainen 09 Aug '07

09 Aug '07

http://dovecot.org/patches/mbox-snarf-plugin.c Also committed to CVS HEAD. Usage: mail_location = mbox:~/mail:INBOX=/var/mail/%u protocol imap { mail_plugins = mbox_snarf } protocol pop3 { mail_plugins = mbox_snarf } plugin { mbox_snarf = ~/mbox } If ~/mbox doesn't exist, nothing special is done. If ~/mbox exists, it's treated as INBOX and mails are moved from /var/mail/%u whenever the mailbox is synchronized. If all the messages couldn't be copied, for example because of out of quota, then none of the messages are copied. I suppose that could be a problem. It might be possible to fix that by changing: if (mailbox_copy(dest_trans, mail, 0, NULL, NULL) < 0) { if (!mail->expunged) { ret = -1; break; } } to just: if (mailbox_copy(dest_trans, mail, 0, NULL, NULL) < 0) { if (!mail->expunged) break; } But I'm not sure about that. Try and tell me. :)

Debugging information would have been really useful, but I did fix one bug and added some more asserts: http://hg.dovecot.org/dovecot-1.0/rev/bd113e9fe67b If it still wasn't fixed, maybe with this change it gives another assert.

[Dovecot] Outlook 2000/2003 frequent disconnect issue
by Jeff Ramsey 09 Aug '07

09 Aug '07

I have been using Dovecot for an IMAP server for a few years now, with no hitch. Even using Outlook 2K/2K3 as a client. Yesterday, I had a user experience the 'Negative UIDs' issue spoken of here: http://wiki.dovecot.org/Clients/NegativeUIDs I performed all of the steps mentioned in this article, and it seemed like it would work properly the first time the user checked their email, and then after that, they would get this error again. I checked to see what the latest stable version of Dovecot was, and decided to upgrade. I was at 0.99.11-8 and the latest stable rpm for my distro was 1.0.2-2. The upgrade went fine. Or so I thought. I am now getting the following message on all Outlook Clients: "Your IMAP Server closed the connection....this can occur if the connection is idle for too long" I have scoured the Internet for this error and have come up with many suggestions, none of which have worked. I have increased Outlook's timeout period to the full 10 minutes, and I have disabled SELinux. None of this seems to have worked. Is there anyone out there who has actually had this issue and resolved it? Can you please help? Thanks, Jeff Ramsey MIS Administrator TMI Forest Products, Inc. jefframsey(a)tubafor.com 360.477.0738 -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

[Dovecot] Database server failure causes endless loop
by Andy Shellam 09 Aug '07

09 Aug '07

Hi, I've just started setting up Dovecot 1.0.1, and made an error in my configuration, which I think has found a potential problem in Dovecot. I'm using PostgreSQL authentication, and set the database host to "localhost", which PostgreSQL doesn't listen on, so libpq is throwing the standard "is the server running?" message. The problem, however, is Dovecot isn't seeming to understand this, and is endlessly looping, trying to query it every 5 seconds. My client (telnet during testing) is simply sitting there waiting for a response, which it's never going to get. After about 5 minutes, Dovecot killed the connection, saying "* BYE Disconnected for inactivity." If this was from an IMAP client, I'm guessing the client would time-out after so long when it doesn't get a response back. Wouldn't it be more sensible for Dovecot to try PostgreSQL, say, 3 times. If unsuccessful, send the client an "internal server error" or something similar? Otherwise if the database server failed, and the client tries to connect, it'd be waiting for at least a minute (or whatever the standard time-out interval is) before failing, whereas it'd be better to see almost instantly if the server's down. Regards, Andy.

[Dovecot] Moving mboxes around
by tomas＠tuxteam.de 09 Aug '07

09 Aug '07

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Dovecot gurus, I have a couple of questions for which I haven't found answers in the docs (which may be well more a limitation of my capabilities than anything else). Here they go: - Is it OK to move mailboxes around from under Dovecot? Case in point: I'm using procmail to pass incoming mail through bogofilter (the standard recipe mentioned in their manpage, which more or less funnels spam into a "spam" mailbox, unsure into an "unsure" and non-spam into "inbox"). From time to time I'd like to clear the spam and unsure mailboxes, using logrotate. Dovecot seems to cope with it. Am I tempting my luck? - Is there a way to tell an external application when mail has been moved by a client? Again: dovecot+bogofilter: from time to time a client checks incoming, unsure and sometimes spam and decides to move --say-- a mail from unsure to spam (deciding it's spam, after all) or similar. This is of course important for the training of bogofilter, so I'd like to trigger a backend action. I see basically two possibilities: - create two more mailboxes, say "spam-indeed" and "ham-indeed". User is told to move mail into these. Ham-indeed gets re-funneled to inbox (or something like that). Manual and error prone. - Use the mail_log plugin (seems more attractive). I still have (distro-provided) dovecot 0.99.14, but this would be a good reason to upgrade. (I still don't see where I get the source mailbox in the mail_log messages from, but that's details now). You get the idea, I think. Anyway, I am interested in any ways to combine dovecot and bogofilter in the backend in a way that I can route user feedback to the filter without putting too much burden on the user. Ideas? Thanks - -- tomás -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (GNU/Linux) iD8DBQFGtuS4Bcgs9XrR2kYRAkiXAJoDJYZC8DYIxFqCw+HEIn0CCNssQwCfaZjh z533XFMH36c4Lemv/+gSn9A= =s87z -----END PGP SIGNATURE-----

Hello Timo, I've noticed that when slapd which I'm using as the passdb and the prefetched userdb is restarted I have to restart dovecot. As a matter of fact, if I don't, I get the following error : -- Jul 2 16:38:39 xxxx dovecot: imap-login: Internal login failure: user=<xxxx>, method=PLAIN, rip=xxx.xxx.xxx.xxx, lip=xxx.xxx.xxx.xxx, TLS Jul 2 16:38:46 xxxx dovecot: auth(default): prefetch(xxx,xxx.xxx.xxx.xxx): passdb didn't return userdb entries Jul 2 16:38:46 xxxx dovecot: auth(default): userdb(xxx,xxx.xxx.xxx.xxx): user not found from userdb -- I'm using dovecot-1.0.1 on FreeBSD 6.2-STABLE with openldap-server-2.3.35_1 (bdb backend). Would some cache-related parameters allow to fix that or will restarting dovecot be always mandatory after an ldap restart ?

[Dovecot] lda: vacation auto-reply for a virtual address
by martin f krafft 09 Aug '07

09 Aug '07

Hi, I am using Dovecot to manage a complex virtual mailbox setup. It's all working splendidly, thanks to the Dovecot LDA. This morning, however, I needed to create a vacation-style autoreply for one of the virtual addresses. I made use of cmusieve, authored a little sieve script, and had it working in no time... until I discovered how limited sieve's vacation module is. Most importantly: it's hardcoded to use the Return-Path of a message, but in this very case, I need to actually use the address in the from header. So I had to give up on sieve and am now looking for another solution, but without much success. Given that mail is delivered by the Dovecot LDA, is there any way to make deliver pass it off to e.g. procmail in such a way that $HOME is set to /srv/vmail/domain.org/localpart, so that procmail can find the .procmailrc?

My company is running a dovecot 1.0.0 server set up with an LDAP directory, mails are delivered to /var/spool/imap and users do not have a real unix home directory on this system. During my internship, I've installed a sieve server (pysieved) that is working with dovecot. But I encountered a problem with the LDAP setup. Pysieved is using dovecot's auth and client sockets to authenticate the user and get it's home directory where it will store sieve scripts, this home directory is also actually used by cmusieve. With our setup, users do not have /home directories on the mail server but the homeDirectory LDAP attribute is used by other services and cannot be modified for dovecot. I know we have the option to create a new attribute, set it to something like /var/spool/imap/<user> for every mail users, and use this new attribute name in dovecot-ldap.conf with the user_db statement. This is actually working on a test environnement, but we wish we could do it without any modification on the LDAP directory. The very precise question is : How can I tell dovecot to compute the « home » path from the login name when using LDAP userdb ? By example, if a user has login name "jdoe", dovecot will authenticate him against the LDAP directory but won't get the home path from it. Instead, it will use the same mail_location path (if possible) or something similar, like /var/spool/imap/%1u/%u . Can I do this without any modification of the source code of both dovecot and pysieved ? Thank you, -- Thibault VINCENT tibal(a)reloaded.fr thibault.vincent(a)reloaded.fr PGP Key : 0x4BA8A39B
