Hi, recently I installed the newest 2.x version of dovecot working with postfixadmin/mysql and it works great, thanks Timo, however I been reading dovecot's mailing list archived messages and haven't run across a good solution for archiving mail with dovecot. There was mention of using rsync but I was looking for incoming mail to be copied to another folder, maybe called archive J, in real time where the user would have only read access to the messages in the archive folder and the expire plug-in would delete messages older then x number of days. Does anyone have an suggestions on how I can implement this, I would also like to hear how some people were implement archiving if they do it differently. Also as far as shared calendars with dovecot what are my options. Sorry if it's a little off topic. Thanks, Paul

[Dovecot] dovecot director terminate ssl ?
by Jan-Frode Myklebust 03 Jan '11

03 Jan '11

I plan on putting two dovecot directors in front of our backend dovecot pop/imap servers, instead of our current haproxy loadbalancing of the connections -- but how do we handle SSL in such a setup. Will all SSL be terminated on the directors automatically, and then proxyed plain text, or is there any configuration needed to achieve this ? Does it matter that the directors are v2.0 while the backends are running v1.2 ? -jf

[Dovecot] RV: Quota ignore subfolders
by Héctor Moreno Blanco 03 Jan '11

03 Jan '11

Please, any help with this issue. Thanks. Héctor Moreno Blanco. -----Mensaje original----- De: dovecot-bounces+hmoreno=gmv.es(a)dovecot.org [mailto:dovecot-bounces+hmoreno=gmv.es@dovecot.org] En nombre de Héctor Moreno Blanco Enviado el: miércoles, 15 de diciembre de 2010 12:48 Para: dovecot(a)dovecot.org Asunto: [Dovecot] Quota ignore subfolders Hello, We have dovecot 2.0.8 in our servers with Scientific Linux SL release 5.2 (Boron). We want to ignore a mailbox and its child mailboxes. A few weeks ago Timo told me to do this in dovecot.conf, create a new namespace which will be the quotaless namespace and edit the quota: namespace { inbox = yes location = prefix = INBOX. separator = . type = private } namespace { location = maildir:%h/Maildir/carpeta1 prefix = carpeta1. separator = . type = private } plugin { quota = maildir:carpeta1:ns=INBOX. quota_warning = storage=75%% /usr/local/dovecot/bin/quota-warning.sh 75 quota_warning2 = storage=90%% /usr/local/dovecot/bin/quota-warning.sh 90 } We also have passdb and userdb with ldap, with dovecot-ldap.conf: pass_filter = (&(objectClass=qmailUser)(uid=%u)(accountActive=TRUE)) pass_attrs = uid=user,userPassword=password, mailQuotaSize=quota_rule=*:bytes=%$ user_attrs = mailMessageStore=home, mailQuotaSize=quota_rule=*:bytes=%$ user_filter = (&(objectClass=qmailUser)(|(mailAlternateAddress=%u)(mail=%u)(uid=%u))(accountActive=TRUE)) We also tried the easy solution which was to indicate a quota rule in order to ignore the mailbox but with no success. It still get every mailbox to calculate the quota. We set mail_debug=yes to see if there was any error, but everything seemed to be ok. Any suggestions? Thank you very much in advanced.

[Dovecot] Dovecot Quota plugin as Couier quota
by Antonio Perez-Aranda 03 Jan '11

03 Jan '11

I get a similar behavior between dovecot quota plugin and courier quota with the attached patch. When the client change flags, then is forced to recalc. This is because I don't know how to get the changed flags on quota sync method. The courier quota behavior is avoid to count all deleted mails, include "mark as deleted" mails. -- Antonio Pérez-Aranda Alcaide aperezaranda(a)yaco.es Yaco Sistemas S.L. http://www.yaco.es/ C/ Rioja 5, 41001 Sevilla Teléfono +34 954 50 00 57 Fax +34 954 50 09 29

[Dovecot] lmtp (xxx@mydomain.yy): Error: user xxx@mydomain.yy: Initialization failed: Namespace '': mbox: mbox requires client_limit=1 for service
by G.Nau 02 Jan '11

02 Jan '11

new Dovecot 2.0.8 installation on Opensuse 11.3 I got the error "lmtp (xxx(a)mydomain.yy) Error: user xxx(a)mydomain.yy: Initialization failed: Namespace '': mbox: mbox requires client_limit=1 for service" while trying to transfer mails by lmtp from postfix to dovecot. I googled and looked on the dovecot wiki about this client_limit issue, but no success. What's the syntax of the client_limit and where to place it? Into which config file? Inside the global namespace doesn't seems to work (error on dovecot start). -What's the side effect of this setting to my IMAP clients? Are multiple imap connections to the same mailbox still possible? Regards Birte Nauer

[Dovecot] listescape breaks acl plugin
by Jens 02 Jan '11

02 Jan '11

Hi all Without the listescape plugin I see the following things happen: - If I share a mailbox, dovecot-acl-list in Maildir root is updated accordingly. - If I create a subfolder in an already shared mailbox the dovecot-acl file of the parent folder is copied to the new folder and dovecot-acl-list is updated as well. When I activate the "listescape" plugin, this doesn´t happen. Additionally (with listescape enabled), if I create a folder which contains a dot and then share that folder the dovecot-acl-list looses all entries except the first found shared folder without a dot in foldername. I Hope this is not a bug but only a configuration issue. Thanks for any hints in advance and best Regards Jens

[Dovecot] Shared Folders via Symlinking
by Adrian Mardlin 01 Jan '11

01 Jan '11

Hi folks, I'm trying to set up shared folders via symlinking and have come across a problem. I created a folder for one user, then symlinked it to another. I figured that one thing that is likely to happen at some point is that user 2 is going to decide they don't want to look at that folder any more, and will delete it, so I tried this. Much to my relief, it didn't delete the actual mails, just the symlink. However, it did alter the dovecot.index.cache file to indicate that the folder had been removed, and subsequent attempts to select this folder via the primary user resulted in an error, "NO Mailbox was deleted under us". I had to delete dovecot.index.cache to get it working again. Sorry - can't bring myself to call folders mailboxes... ;-) Adrian Mardlin in charge @ The Very Good Email Company t 01442 892641 m 07920 102401 f 01442 808081 w www.verygoodemail.com The content of this email and any attachment is private and may be legally privileged.

[Dovecot] Sieve rule issue with certain character sets
by Thomas Leuxner 01 Jan '11

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I have a global sieve rule in place to filter mailing-lists. This has worked well so far. Recently however one subscriber on a list seems to create strange character set encodings in the 'From' and 'To' headers. This leads to unprocessed/unfiltered mails (no errors thrown).

[Dovecot] Dovecot 1.2.12 + Postfix + virtual domains: delivering to system users
by Ran Talbott 01 Jan '11

01 Jan '11

As mentioned in my previous posting, I've set up a mailserver for a domain of Winboxen, authenticated through Active Directory. After some struggles, I finally got that working. But I also need to receive emails for a few system users on the mailserver (like postmaster, and a couple of accounts set up for maintaining the system). I thought, based on the way I read the documentation, that I could just add a "userdb passwd", ahead of the "userdb ldap", and deliver would find their home directory maildirs. The virtual users would fail the passwd search, fall through to the LDAP check, and deliver would drop their mail into their maildirs in the /var/mailstore tree. I knew the system users wouldn't be able to login to the IMAP server, but this isn't a concern. Instead, the system users' mail got bounced, after an auth check via the "master" socket (from Postfix, I guess: it's a transient process) whose details don't get logged. And the virtual users' lookups (done by deliver) returned made-up UIDs and GIDs, and maildir locations (/home/<realm>/<username>) completely different from what the LDAP lookup normally returns (/var/mailstore/<username>). So what am I missing here? I managed to work around this by adding the system users to the Postfix virtual.db, but it would be nice to not need to do that. It would also be nice to neable the system users to check email by logging in to the IMAP serve, but I'm reluctant to even try that after the way delivery went completely wonky. Thanks, Ran

[Dovecot] Can doveadm rebuild thread indexes?
by David Warden 30 Dec '10

30 Dec '10

I'm already using "doveadm search" to update my squat fts indexes (dovecot.index.search and dovecot.index.search.uids) but I'd like to also update dovecot's thread index file (dovecot.index.thread) using doveadm. I checked the new wiki and the archives but didn't see any option for this. (I'm running 2.0.8) The alternative (AFAIK) is to write a script that signs in to IMAP and does "thread references UTF-8 ALL" in each folder. As an aside, could the dovecot LDA do any of this work? I'd surely be willing to spend the resources at delivery time to keep those indexes updated if it meant I didn't have to run a cron job to keep them updated. -David Warden

[Dovecot] LDAP binds
by Trever L. Adams 30 Dec '10

30 Dec '10

I am using 2.0.8. Anonymous binds are no longer supported in the environment I am using. I need to change my userdb ldap setup to bind. I believe the ldap server does Kerberos (or can) authentication. My users are authenticating using Kerberos or Kerberos/PAM. This needs to stay in place. Can anyone suggest how I might go about changing my setup to work? My current ldap setup is as follows (the directories, user id, etc are set statically in the configuration elsewhere): tls = yes hosts = MAILSERVER base = dc=middleearth,dc=sapphiresunday,dc=org ldap_version = 3 user_attrs = userPrincipalName=user user_filter = (&(objectClass=person)(|(mail=%u)(sAMAccountName=%u)(userPrincipalName=%u))) # For using doveadm -A: iterate_attrs = userPrincipalName=user iterate_filter = (objectClass=person) Thank you, Trever Adams -- "Seize the day, put no trust in the morrow!" -- Quintus Horatius Flaccus (Horace)

[Dovecot] dovecot-keywords problem with MDN
by Mauro D. 30 Dec '10

30 Dec '10

Hi all, I have Dovecot 1.2.13 installed. My clients ask why Disposition-Notification is requested every time the mail is moved on a new IMAP folder... I take a look into dovecot-keywords file and I see that: 1) I have only one row 0 NonJunk 2) dovecot-keywords file is not present inside every directory. How I can restore normal status? Where is probably the problem? Thanks Mauro D.

[Dovecot] IMAP messages not being marked read
by void372＠transientvoid.com 30 Dec '10

30 Dec '10

I recently moved from Fedora 13 to Fedora 14 and consequently to dovecot 2.0.8. Since then, I have observed that messages are not being marked as read in all cases. The general behavior is: 1. Use my mail client to read all unseen messages. All mail folders show no messages unread. 2. Tell mail client to check for new mail. 3. Mail client now says that some folders have new mail (1 or more messages) 4. Clicking on a folder with new mail (say with 6 unread) shows that there are no unread messages. I have observed this behavior using both kmail and squirrelmail so do not believe it is a mail client problem. I have maildir folders to which mail is delivered using procmail recipes directly to the appropriate dovecot folder. In these folders, I notice that the "cur" directory has a matching number of messages that do not have an "S" flag on the end of the file name. For example: # ls .fedora-list/ cur/ dovecot.index.log new/ dovecot.index.cache dovecot-uidlist tmp/ # ls .fedora-list/cur 1293379204.26554_1.nehalem.home.rainbowdreams.com:2,S 1293379206.26571_1.nehalem.home.rainbowdreams.com:2, 1293379207.26581_1.nehalem.home.rainbowdreams.com:2, 1293380106.26744_1.nehalem.home.rainbowdreams.com:2, 1293380106.26748_1.nehalem.home.rainbowdreams.com:2,S 1293381904.26876_1.nehalem.home.rainbowdreams.com:2,S 1293383704.26978_1.nehalem.home.rainbowdreams.com:2,S 1293384604.27005_1.nehalem.home.rainbowdreams.com:2,S 1293385504.27067_1.nehalem.home.rainbowdreams.com:2,S 1293386404.27105_1.nehalem.home.rainbowdreams.com:2,S 1293387305.27158_1.nehalem.home.rainbowdreams.com:2, 1293387305.27166_1.nehalem.home.rainbowdreams.com:2, 1293388204.27193_1.nehalem.home.rainbowdreams.com:2, 1293389105.27234_1.nehalem.home.rainbowdreams.com:2,S 1293390005.27292_1.nehalem.home.rainbowdreams.com:2,S 1293390006.27298_1.nehalem.home.rainbowdreams.com:2,S 1293392706.27400_1.nehalem.home.rainbowdreams.com:2,S 1293392706.27406_1.nehalem.home.rainbowdreams.com:2,S 1293393611.27515_1.nehalem.home.rainbowdreams.com:2,S 1293396304.27673_1.nehalem.home.rainbowdreams.com:2,S 1293396305.27675_1.nehalem.home.rainbowdreams.com:2,S 1293398104.27743_1.nehalem.home.rainbowdreams.com:2,S 1293399003.27966_1.nehalem.home.rainbowdreams.com:2,S I have so far been unable to observe a pattern as to which messages get affected. I made the assumption that perhaps the issue is a conversion issue in my existing maildir folders, but this does not appear to be the case. When I moved the existing directory out of the way and started with a fresh empty directory the issue has come back after a day or two. Unfortunately, my install of Fedora 14 overlaid the partition with Fedora 13, so I cannot confirm the version of dovecot I was using with no issues. (so very glad I use separate disk and partition for the OS!) I can say that all configuration was in one dovecot.conf file, not the multiple conf.d files I see on Fedora 14. Any assistance on what to troubleshoot next is greatly appreciated! The info about my dovecot is shown below. The maildir's are on local LVM/RAID and not remote.

[Dovecot] Dovecot consulting companies
by Timo Sirainen 30 Dec '10

30 Dec '10

Once in a while someone asks about companies who could help installing / running / etc. their mail server. I don't really know many, so I thought I'd add a wiki page about it. Feel free to add your company on the list if you offer some Dovecot related services. Write also a few words what type of services you offer. http://wiki2.dovecot.org/Consulting I'll add a link there once at least one company is listed. :) Oh and if it's not clear above, I don't mean that the list should contain companies that only offer email accounts (Dovecot or not).

[Dovecot] Reverting from 2.0. to 1.2
by Thomas Hummel 30 Dec '10

30 Dec '10

Hello Timo, I switched this morning from dovecot-1.2.12 to 2.0.8 with a basic setup (high performance login mode, Maildir, everyhing on NFS, one shared but unused namespace). No problem so far except that some Thunderbird users who wouldn't succeed in moving messages from some one folder to another. They'd get a message about some illegal character in the mailboxname (already existing mailbox of course). This is user input so I don't have any details nor sufficient element to consider it a real problem. A Thunderbird restart seems to solve the problem. My questions were : . is there a different handling in the hierarchy separator (internal or advertized for the namespace) ? (I use "/" for both namespaces and "." since in Maildir). . is there a different handling in the non-ASCII mailbox names ? Could it be related ? . if something goes really wrong, is it safe to revert to 1.2.12 ? Maybe some files has non-compatible format (dovecot-uidlist, indexes, ...) ? Thanks. -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

[Dovecot] over quota issue
by PA 30 Dec '10

30 Dec '10

I have a situation where if a user is over quota and sending through postfix I get an error, now this error only happens if the user is over quota, otherwise it works with no problem. However if sending using /usr/local/libexec/dovecot/dovecot-lda it works every time even if overquota, any ideas? I just can't seem to figure this one out.

[Dovecot] Dovecot 1.2.12+Postfix+Active Directory: virtual domain name dropped.
by Ran Talbott 30 Dec '10

30 Dec '10

I have a Windoze-only client who wants to move their mail hosting from godaddy.com hosting to an in-house system. I'm pitching Linux as an alternative to Exchange, and trying to set up a demonstration system for them. While a long-time Linux user, my server admin experience has been in setting up front-ends (mostly Apache-based web interfaces) for the embedded systems I specialize in. The goal is to have an IMAP server where the users don't have Linux IDs, and only need to manually login to the Active Directory domain controller. The client has multiple Internet domains, but all users are in the same Active Directory realm internally. With the help of the how-tos at linuxmail.info, I got the system to the point of being able to authenticate logins for both IMAP and SMTP (usng dovecot-SASL). I tried using PAM first, but it didn't work: running kinit from the command line takes over 90 seconds to get a ticket, and Dovecot timed out after 60 on every login attempt. So I switched to LDAP. Note: I still don't understand why, but authentication through Active Directory didn't work until I changed the querying distinguished name from the "cn=,dc=,dc=" format to "user(a)xxxx.local" format. I have Postfix using dovecot-deliver as the LDA, but I hit a snag: deliver is not putting the domain name in the path to the maildir. I have the active directory query set as: user_filter = (&(objectClass=user)(samaccountname=%n)) user_attrs = =home=/var/mailstore/%d/%n. =uid=501, =gid=501, \ =mail=maildir:/var/mailstore/%d/%n/Maildir/ When I send mail to testing.testing(a)xxxx.xxx (real domain obscured), I see this in mail.log Dec 23 10:49:24 IBMUBUNTU1 dovecot: auth(default): master in: USER#0111#011testing.testing(a)xxxx.xxx#011service=deliver Dec 23 10:49:24 IBMUBUNTU1 dovecot: auth(default): ldap(testing.testing): user search: base=dc=lawley, dc=local scope=subtree filter=(&(objectClass=user) (samaccountname=testing.testing)) fields= Dec 23 10:49:24 IBMUBUNTU1 dovecot: auth(default): ldap(testing.testing): result: objectClass(?unknown?)= cn(?unknown?)= sn(?unknown?)= givenName(?unknown?)= distinguishedName(?unknown?)= instanceType(?unknown?)= whenCreated(?unknown?)= whenChanged(?unknown?)= displayName(?unknown?)= uSNCreated(?unknown?)= uSNChanged(?unknown?)= name(?unknown?)= objectGUID(?unknown?)= userAccountControl(?unknown?)= primaryGroupID(?unknown?)= objectSid(?unknown?)= sAMAccountName(?unknown?)= sAMAccountType(?unknown?)= userPrincipalName(?unknown?)= objectCategory(?unknown?)= Dec 23 10:49:24 IBMUBUNTU1 dovecot: auth(default): master out: USER#0111#011testing.testing#011home=/var/mailstore//testing.testing. =uid=501#011gid=501#011mail=maildir:/var/mailstore//testing.testing/Maildir/ i.e., the domain does not appear in the paths to the home directory or maildir. I found a bug report in the mailing list that looks like it might be the same problem (%d not supported in user_attrs), but the fix it references is for 2.0. Is this a known problem in 1.x? Is there a fix/workaround for it? E.g., could I have Postfix generate the maidir path and pass it to deliver as the "-m" parameter? Thanks, Ran

[Dovecot] Is this really a user agent issue?
by Phil Howard 30 Dec '10

30 Dec '10

I suspect this is a user agent issue, given that Evolution is flaky in so many areas. When I deliver mail to a subfolder/subbox (e.g. the -m option in the deliver command), and Evolution doesn't know of it, yet, creating it fails, and Evolution still can't get to it. Doing things the other way around (create it in Evolution first, then deliver to it) works fine. Seems to be silliness to me. Just wondered if any Dovecot aspects might be involved ... such as the fact that the case is different (e.g. "INBOX" in the filesystem, but "Inbox" in Evolution). -- sHiFt HaPpEnS!

[Dovecot] How to get a working dovecot.conf?
by oddball56 29 Dec '10

29 Dec '10

Hi, I installed openSUSE 11.3 server version, and followed the guidelines from: http://www.howtoforge.com/perfect-server-opensuse-11.3-x86_64-ispconfig-3 Everything works, accept loggin into dovecot. For many days i tried to get logged into dovecot, from localhost, from other pc in the lan, from squirrelmail, not possible. I read manuals on http://wiki.dovecot.org/ and tried to set the passwd db like: auth default { .. passdb passwd-file { args = /etc/passwd.dovecot } .. The "args" were not accepted according to the output from dovecot -n As now i installed dovecot 20, with a fresh dovecot.conf. Ofcourse this was not working, so i 'updated' ISPConfig. Now my dovecot.conf is a mess, and i get errormessages like: Dec 20 21:00:02 AsusTT-sfn6 postfix/smtpd[7073]: fatal: no SASL authentication mechanisms And from dovecot: dovecot.pem missing from /etc/ssl/certs, so no ssl login possible also Now i am checking dovecot -n line by line and this message pops out: mail_plugin_dir: access(/usr/lib/dovecot/modules/imap) failed: No such file or directory passdb { driver = pam } passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } furtheron: ssl = no userdb { driver = passwd } userdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } it has 64 lines. first and last_valid_uid and gid are set to 5000. In this conf i did not change anything. I would realy appreciate some help, as my only goal was to set up an imap server so i can access my mail from all over the world, and have all mail in 'one' central place, instead of scattered all over many pc's and laptops. The irony is that evrything but this works ;-p tia, for an answer.

[Dovecot] director in large(ish) environments
by Cor Bosman 28 Dec '10

28 Dec '10

Hey all, just wondering who here is running the director service in a larger environment. I just switched our whole production setup to the director and am quite pleased with the result. We're doing a peak of about 25000 tot 30000 concurrent sessions on 3 servers. But ive shut 1 server down a couple of days ago to see what would happen and 2 servers carried the load easily. (16 CPU, 24GB memory servers). If others are using the director on larger setups maybe we can all post when things do or dont work well. Now to see if the solution is better than the problem :) Cor

[Dovecot] Migrate from Maildir to mdbox
by Odhiambo Washington 28 Dec '10

28 Dec '10

Looking at http://wiki2.dovecot.org/Migration/MailFormat, I do not see much on how to do a migration from Maildir to mdbox. That page isn't quite updated it looks. I have several domains (virtual) with the following storage layout: /var/spool/virtual/$domain. So the users have their mail stored as follows: /var/spool/virtual/domain1/$user/Maildir /var/spool/virtual/domain2/$user/Maildir /var/spool/virtual/domain3/$user/Maildir /var/spool/virtual/domainN/$user/Maildir >From the wiki, I am told the steps to take are: 1. Set mail_location=mdbox:~/mdbox 2. Run "doveadm mirror -u username maildir:~/Maildir" The instruction above confuses me because in my situation, I don't have a "username" per se. dovecot-deliver knows how to figure out my usernames and their mail_location settings. How do I derive my "username" when users are virtual, stored in MySQL back end? Again, the right command seems to rely on dsync, not "doveadm mirror". I could manually get all the values for the users for each domain and run: dysnc -u $u -o "mail_location=maildir:/var/spool/virtual/domain1/$u/Maildir" mirror "mdbox:/var/spool/virtual/domain1/$u/mdbox" This is so manual, especially because I have to (if I remember well) create /var/spool/virtual/domain1/$u/mdbox (and have the permissions right) before running dysnc. Is there an easier way out, perhaps?? -- Best regards, Odhiambo WASHINGTON, Nairobi,KE +254733744121/+254722743223 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Damn!!

[Dovecot] Postfix - deliver problem.

[Dovecot] Kicking by dovecot as proxy?
by Antonio Perez-Aranda 27 Dec '10

27 Dec '10

I'm using dovecot 2.0 as proxy to make easy the migration from Courier to Dovecot. ¿Is it possible to use doveadm kick on a proxy connection?

[Dovecot] Status update
by Timo Sirainen 27 Dec '10

27 Dec '10

Just in case you're wondering: I should hopefully soon get back to answering all the pending mails and start coding. I moved back to Finland a week ago. I should get my proper internet connection on Wednesday, although this 3.5G isn't too bad either. I couldn't get my old Mac Mini to work properly anymore so I went and bought a new machine. Dovecot recompiles in 43 seconds now. :)

[Dovecot] passwd, gid and uid
by Mauricio Tavares 25 Dec '10

25 Dec '10

I forgot the answer for this: in http://wiki.dovecot.org/AuthDatabase/PasswdFile, we have the passwd file defined as user:password:uid:gid:(gecos):home:(shell):extra_fields What should the uid and gid be associated with? In my setup I told postfix to use Dovecot LDA's deliver, which then is saving files as uid:gid of 1500:1500. How would that affect the uid:gid used in the passwd file? From what I read in the dovecot's wiki, you want them *not* to be anything that has the rights to access the emails. So, does that mean any value for them will do?

[Dovecot] Maildir feature I'd like to see - SSD for newer messages
by Marc Perkel 24 Dec '10

24 Dec '10

SSD drives are very fast but expensive. So I have a crude idea that I'd like to see. May not be practical but would like to get some thoughts on it. Some new SSDs use SATA 3 (6gb/sec) with 355/mb/sec read speeds and 215MB/sec write. Put these in raid 0 and it screams! Can you imagine how fast that would be? What would be nice is if new email were on faster drives with old email being migrated to larger mechanical cheaper storage. Perhaps messages over a month old? From dovecot's perspective it would sort of all look the same but maybe one a week a script would run migrating older messages to slower media. It would also make backups easier. The faster newer messages could be archived hourly. On the weekend after the archiving script was run the older message could be backed up once a week. I'm not sure what it would take to make dovecot seamlessly access email from two different locations or if this is practical. Just wanted to throw the idea out there to see if something sticks.

[Dovecot] Is this an index problem?
by Chris Barnes 23 Dec '10

23 Dec '10

This is my first post to this list/gmane newsgroup, so please be gentle with me.... :-) Here's my situation: I have a user (the "main boss secretary") who uses MS Outlook 2007 as her email client. She has over 46,000 messages in her inbox, with nobody knows how many more in 75+ different folders & subfolders. Surprisingly, her response time wasn't too terrible up until we had to reboot our mail server the other day (actually, restoring the entire server from a backup). Now it takes anywhere from 10 to 60 seconds for her to switch from 1 folder to another. Details: * Server is Debian running Postfix and Dovecot (both the current release). Using Maildir format stored in the user's ~/Maildir folder. * User connects to server via Imaps. Connection is local using gigabit network (ie. it ain't the network). * Yes, we did all the things on the Outlook side -thinking that is where the problem lays. Rebuild the .pst file, had Outlook re-index, compacted the .pst file, etc. So now I'm thinking that maybe I need to just wipe out all of the ~/Mailder/dovecot* files (including all those in sub-directories) and let it all reindex. Which begets 3 questions: (1) will this help? (2) anyone have a shell script that will remove all those dovecot* files from the user's directory AND all the sub-directories? (3) Any other suggestions I might be missing? -- Chris Barnes

[Dovecot] Deliver limit based of number of destination recipients and size of mails, any option to do that?
by Andrés Yacopino 23 Dec '10

23 Dec '10

I have a mail server with postfix, dovecot (1.2.15) and deliver lda (dovecot) with 350 users. I have the problem that in this christmas the employees are sending some big files (mainly powerpoints files) to a lot of recipients, because of that the server get a lot of charge (is a Xeon quad core 5405 with 4GB of Ram), i have four disks in Raid 5 configuration (HP E200 controller, not very fast) Is there any option to limit this type of delivery, the total size of the mails delivered to each user (total recipients * size of mail), in dovecot deliver. I don't want to limit the concurrent delivery more lower than 350 recipients and the max size of the mail we can send is 15M. Thanks a lot, -- Andrés Fernando Yacopino

[Dovecot] trying to make cmusieve happen globally
by Phil Howard 22 Dec '10

22 Dec '10

In Dovecot 1.1.11 cmusieve is apparently integrated in the Ubuntu 9.10 package "dovecot-common" since the files are there. I am wanting to right now just do a very basic test of the setup to see how it runs before doing more sophisticated steps that could obscure any errors or bugs (e.g. unit testing). So I took the following example sieve script from the wiki1 documentation: require "fileinto"; if header :contains "X-Spam-Flag" "YES" { fileinto "spam"; } and recoded it to skip the test and just always do the fileinto step like so: require "fileinto"; fileinto "spamtest"; Then I configured my dovecot.conf file (via dovecot-postfix.conf it really points to) by setting: protocol lda { ... mail_plugins = cmusieve mail_plugin_dir = /usr/lib/dovecot/modules/lda ... } and: plugin { sieve_global_path = /etc/dovecot/sieve-global.d/spam.sieve } I manually compiled /etc/dovecot/sieve-global.d/spam.sieve so there also exists /etc/dovecot/sieve-global.d/spam.sievec in the same directory. Then I restarted both Dovecot and Postfix. Mail is being delivered, but still only to the same place it always has. The filesystem shows these sieve files are not being accessed at all. I've read documents http://wiki1.dovecot.org/LDA/Sieve and http://wiki1.dovecot.org/LDA/Sieve/CMU to come up with this. But it just doesn't seem to be happening. So I guess it is a good thing I've broken my testing down into smaller units. Anything standout that I misinterpreted about the documentation? If not, I can post the whole config files (in case there is a conflict with something else I have done). FYI, I'm only trying to do a global sieve, not per-user sieve scripts. I'll tackle per-user stuff at a later date, after the global is working. -- sHiFt HaPpEnS!

[Dovecot] Per user quota on MySQL

I understand that killing dovecot/auth is not, but Dovecot could survive this easily, if recreating and re-using the new socket file would work. And loosing dovecot/auth happens sometimes (I don't yet now why). Thanks,

[Dovecot] Moving email between folders outside of IMAP context
by Phil Howard 21 Dec '10

21 Dec '10

I'd like to run a script from cron that will scan certain mailboxes and move selected mail from one folder (usually INBOX) to another folder. The basic idea is to move previously detected spam based on headers prepended to the mail. Since I am not able to figure out how to get Postfix to invoke deliver with the -m option in these cases, and not in others, this is one idea I have come up with to deal with it. The big (hopefully obvious) complication seems to be getting the indexes updated. Is there a way to move mail this way AND then have the indexes updated to reflect that move (maybe even if regenerating the entire index all over again)? -- sHiFt HaPpEnS!

Hi there, is it possible in any way to have private seen flags for users in a shared mailbox? http://wiki2.dovecot.org/SharedMailboxes/Shared says no, but i'm not sure, if newer mailbox formats can do this... like mdbox oder something like that. thanks for your help Tobi --

[Dovecot] Maildir and Solaris UFS acls
by Tom Lieuallen 21 Dec '10

21 Dec '10

I have a centrally located shared imap folder location. We have several maildir folders with different file system permissions. They are for several groups of people who are loosely related for support purposes. All mail gets delivered to queue1 just fine. The files are group writable by group1. Some of the mail gets moved via imap to queue2. Queue2's maildir tree is configured with Solaris UFS acls such that any new files are read/write by group1 or group2. If a new file is created within queue2 anywhere, it has the correct permissions. However, if a message is moved from queue1 to queue2, it retains the permissions that it had within queue1. This is what happens if I use 'mv' within the file system, btw. Is there any way to configure dovecot such that if a person moves or copies a message to another imap folder, it creates a new file instead of doing a link or mv or whatever? If not, no problem; I was just hoping for an elegant solution to my particular problem. :-) queue1 - read/write by group1 queue2 - read/write by group1 & group2 through solaris ACLs BTW, if any file whatsoever in queue2 is not readable by group2, those in group2 cannot read _anything_ in queue2. thanks Tom Lieuallen

[Dovecot] Best way to move mail to an archive
by Richard C. Cox 18 Dec '10

18 Dec '10

Hello all...new to dovecot and this list. I have a question that may have been answered before, but I can't find anything yet that addresses it directly. I installed dovecot 2.0.8 (+postfix, fetchmail) on a small server to manage several e-mail accounts. I love this software! So, to back to the question: I'd like to archive e-mail as it ages into a single IMAP archive directory. Ideally, I would like to set up a cron job to search for e-mail in all of my imap directories that older that 'X' days and move it to the archive directory. I know that dovecot wants to manage e-mail movement thru the IMAP interface, so I'm leery of just using ordinary Linux commands to move mail around and bypass the IMAP protocol. Does anybody have any recommendations about dovecot/IMAP safe commands I could use to accomplish this task? Thanks in advance and I apologize for not being more knowledgeable about this subject. Regards, Richard

[Dovecot] Problem with expunge
by Jeff Mitchell 18 Dec '10

18 Dec '10

I'm running Dovecot 2.0.8. The other day I tested doveadm expunge on a test Inbox with a few messages received over the course of a day, and using savedbefore <a few hours>, and it seemed to work. However, today I was testing converting some maildirs over to sdbox, and noticed odd behavior: it's deleting all messages in the specified folder instead of just the ones matching the condition I'm using ("savedbefore 4w"). The command I'm using is "doveadm -Dv expunge -A mailbox Trash savedbefore 4w" Because of the conversion, all of the ctimes for all of the files are actually the same (basically, a few minutes ago), due to the converstion to sdbox from maildir, so I would expect that either it doesn't delete any of them or looks inside at some header of the mail (half of which was received/placed into Trash before 4w ago and half of which wasn't). I definitely don't expect full-on deletion... Any idea what's going on? Thanks, Jeff

Hi, after deciding to use Dovecot 2.0.8 as a postfix LDA using mysql DB I'm running into some issues. I started to follow, http://wiki.dovecot.org/HowTo/DovecotLDAPostfixAdminMySQL but noticed that the auth settings on the config changed, after looking through the dovecot wiki I think I have that issue fixed.

[Dovecot] namespace and list=children inconsistencies
by Holger Mauermann 17 Dec '10

17 Dec '10

Hi, after setting up a new Dovecot server with shared and public namespaces, both with hidden=no and list=children, I see some inconsistency in the folder listing. . NAMESPACE * NAMESPACE (("" "/")) (("Shared/" "/")) (("Public/" "/")) . OK Namespace completed. . LIST "" * * LIST (\HasNoChildren) "/" "INBOX" * LIST (\Noselect \HasChildren) "/" "Shared/user(a)do.main" * LIST (\HasNoChildren) "/" "Shared/user(a)do.main/INBOX" * LIST (\HasChildren) "/" "Public" . OK List completed. . LIST "Shared/" * * LIST (\Noselect \HasChildren) "/" "Shared/user(a)do.main" . OK List completed. . LIST "Public/" * . OK List completed. With LIST "Shared/" the other users INBOX is missing, so with namespace capable clients like Thunderbird it is impossible to see or subscribe this folder. The "Public/" namespace has some subfolders, but only for other acl_groups and I don't have rights to access any of them. So the LIST "Public/" looks good. However, with LIST "" * it is shown without the trailing slash and with \HasChildren where it should be hidden. Here is the relevant doveconf -n output: ... namespace { list = children location = maildir:%%h/Maildir:INDEX=~/shared/%%u prefix = Shared/%%u/ separator = / subscriptions = no type = shared } namespace { list = children location = cydir:/var/spool/imap/public:INDEX=~/public prefix = Public/ separator = / subscriptions = no type = public } ...

[Dovecot] How to avoid "authenticated user not found" - messages when using multiple Ldap userdbs/passdbs?
by Sebastian Urbanneck 16 Dec '10

16 Dec '10

Following: We've got a Dovecot 1.0.10 running on Ubuntu Hardy. Till now we used to have only mail accounts under our own domain, but since we're also a webhoster the people began to ask if there is a possibility to use there own Domains in there mail address. For addressing this we changed our Ldap Tree Structur: users which had been there befor remain in there old subtree, new accounts for Virtual Domains are located below an "vd=<domain>,ou=domains,..." subtree. The main Problem at this: old users are used to login only with their username and password, new users has to login via their complete mail address and their password. This is not going to change in the future so I tried to do this: Using two userdb/passdb - entries, in each case one for the old users and one for the new ones. If a user is not found through the first request the second is tried. If this failed too, the user gets rejected. The Problem with this: when not found during the first try the request logs an "authenticated user ot found" - message, no matter if trying via the second etry is successful. Is there a way to tell dovecot, that the user is not "not found" until __both__ requests failed? Regards Sebastian

[Dovecot] adding servers to director_mail_servers
by Cor Bosman 16 Dec '10

Is there a specific order in which one has to add servers to director_mail_servers, Let's say I have 20 loadbalanced director servers (I dont, but for arguments sake). I want to add 5 servers to director_mail_servers. If I do this by restarting each director server 1 by 1 with an updated conf, it seems the 5 new servers dont get added. Or at least I dont get what makes it work eventually. Only after restarting a few times they seem to all want to agree on the new list of servers. Cor

[Dovecot] users's mailboxes = mbox , shared mailboxes = maildir ... is it possible ?
by Frank Bonnet 16 Dec '10

16 Dec '10

Hello I solved my previous SSL problem by reinstalling dovecot2 ... :-) at FreeBSD 8.1 Now I'm using dovecot 2 , cool ... Actually my production mail server runs with MBOX format but reading the dovecot 2 wiki I read shared mailboxes are only working well with Maildir format. As I would like to setup some shared mailboxes, is it possible to have MBOX format for normal users ( UNIX NIS users ) and Maildir format for shared mailboxes to gain access to the per-user \Seen flag Or do I have to convert ALL my server to Maildir format ? Thanks a lot for your help

[Dovecot] Trying to populate dovecot with outlook contacts
by Spyros Tsiolis 15 Dec '10

15 Dec '10

Hello, What the subject says. I am trying, that is. OK, here's the story. Users very lazy. Don't want to write down their contact details from scratch. Here's what I thought : migrate (export?) contacts from outlook to mozilla thunderbird. Then find a way to make thunderbird "talk" to dovecot, so that the latter can import the contact details from mozilla tb. Any ideas ? Will it work ? Am I ranting ? :-) Thank you all, s. ---- "I merely function as a channel that filters music through the chaos of noise" - Vangelis

Regarding Dovecot 1.2.x, for maildir, I believe it would be something like this: mail_location = maildir:~/Maildir:INDEX=MEMORY The ":INDEX=MEMORY" disables writing the index files to disk, and as the name implies, I believe, simply keeps indexes in memory. The docs say: "If you really want to, you can also disable the index files completely by appending :INDEX=MEMORY." My read of that is that indexing isn't disabled completely, merely storing the indexes to disk is disables. The indexes are still built and maintained in memory. Timo, is that correct? Also, due to the potential size of the index files (mine alone are 276 MB on an 877 MB mbox), you'll need to do some additional research to see if this is a possibility for you. If using a ramdisk, 100 mail boxen like mine would require ~ 27.6 GB or RAM just for the index files. This would not be logical to do or feasible given the amount of RAM required. I don't know if, or how much, storing them in RAM via :INDEX=MEMORY consumes, as compared to using a ramdisk. The memory consumption may be less or it may be more. Timo should be able to answer this, and give a recommendation as to whether this is even a sane thing to do. -- Stan

[Dovecot] Connection queue full on 2.0.8

[Dovecot] question about snarf plugin in dovecot 2
by Tom Lieuallen 15 Dec '10

15 Dec '10

I'm trying to get the snarf plugin working with dovecot 2.0.7. Specifically, I want to use the UW-IMAP style optional snarfing. I'm looking at the wiki2 documentation. The first question is whether the UW-IMAP optional snarfing will require any changes to the mail_location. The first section suggests (but doesn't specifically state, which I'd propose be clarified) that mail_location be updated to point at ~/mbox for INBOX. However, with the optional snarfing, sometimes inbox will be at /var/mail and for some users, it'll be ~/mbox. What, if anything, do I do to mail_location? Does it matter where (in which config file) the plugin block is placed? I put all of my snarf configuration in 10-mail.conf. It's not working; not snarfing and not reading mail from ~/mbox (how would it, I have yet to tell it to). The following are excerpts from 10-mail.conf mail_location = mbox:~/mail:INBOX=/var/mail/%u:INDEX=/a2/imap-index/%u .... namespace { type = private separator = / prefix = inbox = yes } .... namespace snarf { prefix = /snarf separator = / location = mbox:/private/dovecot/var/run/dovecot/empty:INBOX=/var/mail/%u:INDEX=MEMORY list = no hidden = yes } plugin { snarf = /snarf/INBOX mbox_snarf = ~/mbox } Thank you BTW, the dovecot-2.0.7/docs/wiki appear to be from wiki1, not wiki2... :-) Tom Lieuallen Oregon State University

[Dovecot] After-delivery sieve processing
by Daniel L. Miller 14 Dec '10

14 Dec '10

Is it possible to run sieve against an existing mailbox? My application: I've got a mailbox that stores status messages from multiple sites. It's easier to check up on recent events by having them all in one folder. However, after I've read them, I'd like to have them archived to individual folders per site. I currently have a sieve script that uses "fileinto" to sort the mails - but I'm thinking of removing it from deliver if I can run it as a manual job later. I suppose another method would be to duplicate the mails on delivery into both the main folder and the per site folders, then delete after I've read them - but for whatever reason that strikes me as inelegant. -- Daniel

[Dovecot] Migration from UW-IMAP
by Daniel Senie 14 Dec '10

14 Dec '10

I am attempting to test out dovecot on a server on a separate IP address from the live, functioning UW-IMAP. I am having mixed results with dovecot. An entirely new account that's never been used with UW-IMAP seems to work fine, but that's really not the point of the exercise. If I try changing over an existing account to use dovecot, I get a variety of issues. Testing with Apple Mail.app, if I synchronize the account, the INBOX stops displaying. So off to plan B, and debug via command line commands. I tried connecting to Dovecot. It was able to list the mailboxes for me. I asked for status on INBOX. Sometimes I get an error back in the IMAP stream, sometimes not. Either way, the log shows complaints about creating mail/.imap and below (we use mbox format, plus /var/mail/%u for inbox). I have active namespace compatibility recommended by the Wiki so that clients specifying "mail/" and clients not specifying an imap path both work. With the test account, I proved this functionality is working. At this point I clearly have some issues, and could use some help figuring out what to ask for help with, i.e. how to proceed to debug this without damaging the existing UW-IMAP setup in the process. The goal is to cut over to dovecot once I can be sure it really is working compatibly, but until then I have a large user base and can't blow everything up. And yes, I really, truly have RTFM (i.e. read the Wiki, the troubleshooting pages, the migration pages).

[Dovecot] Incorrect W value after filesystem corruption
by Bob 14 Dec '10

14 Dec '10

Dec 14 00:15:54 vm dovecot: IMAP(####@####): Maildir filename has wrong W value: /var/vmail/#####/####/cur/#########.M###########.??.????.??.??,S=4951,W=5057:2,RSa Dear Dovecot elite, This morning I woke up to find my mail server hard disk controller had gone crazy and decided to corrupt my file system. After over eight passes with the fsck and a new machine I have mostly recovered but this being a personal server the backups were a half-job. So for speed I recovered the mail directly off the bad file system. Most of the data was fine but a few files were corrupt and as a result I have found Dovecot to be a real pain when it comes to handling a wrong W value. I am having to separately look at the mail.log and just systematically remove the W value as a quick work-around. But it seems to me that it would be much easier to have this done by Dovecot when it realises it has this wrong value, especially as Dovecot seems to drop the connection of that user after encountering this problem. Can I suggest as an improvement this scenario is handled better? I saw one posting which said "this should never happen" but clearly it can and I think there could be better handing of it perhaps?

[Dovecot] Courier-mta with Dovecot LDA
by komodo 14 Dec '10

14 Dec '10

Hi all I have setup dovecot lda instead of maildrop on my courier server. Delivery is working, sieve plugin too, but i can't figure out why lda can't send emails via sendmail (vacation). I always get error Error: Sendmail process terminated abnormally, exit status 67 And i know why, but i don't know how to setup lda to make it work . Here is .courier file where is redirect to lda. | /usr/libexec/dovecot/deliver -a $RECIPIENT -f $SENDER But the deliver does not pass recipient address to sendmail. Here is some output of strace execve("/usr/libexec/dovecot/deliver", ["/usr/libexec/dovecot/deliver", "-a", "komodo@somedomain", "-f", "someuser@somedomain"], [/* 22 vars */]) = 0 So it's clear that deliver have those variables, but then i can see this execve("/usr/sbin/sendmail", ["/usr/sbin/sendmail", "-i", "-f", "<>", "--", "someuser@somedomain"], [/* 2 vars */] <unfinished ...> And there is empty -f , so here is the problem. How should i setup this to make it work correctly ?

[Dovecot] FTS and compound searches
by Tony Pyro 13 Dec '10

13 Dec '10

Hello, New subscriber here. I noticed that the FTS index is not used in compound searches. Is this expected? Tested in 2.0.0 and 2.0.8: . search BODY "waldo" * SEARCH . OK Search completed (0.000 secs). . SEARCH CHARSET UTF-8 OR SUBJECT "waldo" FROM "waldo" * SEARCH . OK Search completed (1.768 secs). . SEARCH CHARSET UTF-8 OR SUBJECT "waldo" BODY "waldo" * OK Searched 0% of the mailbox, ETA 9605:25 * OK Searched 4% of the mailbox, ETA 6:39 * OK Searched 6% of the mailbox, ETA 6:58 * OK Searched 8% of the mailbox, ETA 6:54 It's a problem for us because the Afterlogic webmail client does not offer a body-only search. The two search options are From + To + Subject, or "entire messages", which puts together a large OR query: SRCH1069 SEARCH CHARSET UTF-8 OR (OR (OR FROM "waldo" TO "waldo") SUBJECT "waldo") BODY "waldo" I also checked to see whether the header fields are included in the FTS index but it didn't appear so. I got more results from the search "TO gmail.com" than from "BODY gmail.com" plugin { fts = squat } protocol imap { mail_plugins = " fts fts_squat" } Thanks!

Hello We are using dovecot 1.2.x. In our setup we will have 1200 concurrent imap users (maildirs) and we have 2xraid5 sas 15k diks mounted by iSCSI. The dovecot server (RHEL 5 x64) is a virtual machine in our vmware esx cluster. We want to minimize disk I/O, what config options should we use. We can "exchange" CPU & RAM to minimize disk i/o. Should we change to dovecot 2.0? Maybe mdbox can help us? Maybe ext4 instead of ext3? Any idea is welcome. Regards Javier

[Dovecot] Pigeonhole 0.2.2 - managesieve supports virtual namespaces?
by Tom Talpey 13 Dec '10

13 Dec '10

I got around to trying the 0.2.2 managesieve listener and it's not working for me. As soon as the client authenticates, the connection is closed and the following is logged on the server: > Dec 13 11:48:30 managesieve(xx(a)yy.com): Error: user xx(a)yy.com: Initialization failed: Namespace 'Mobile/': Unknown mail storage driver virtual > Dec 13 11:48:30 managesieve(xx(a)yy.com): Error: Invalid user settings. Refer to server log for more information. I do have such a virtual namespace defined in dovecot.conf, obviously, and it works fine with dovecot 2.0.8. Additionally, the sieve plugin is working fine for lda, dovecot's deliver is executing it perfectly. Do I need to add a setting or plugin to "protocol managesieve" for this? Combed the wiki to no avail.

Is this possible, or will I have to use another approach?

[Dovecot] Feature request
by Nikita Koshikov 13 Dec '10

13 Dec '10

Hello Timo, and all. Preface: From time to time we have problems with thunderbird. The problem is that mail client begin to sync users inbox (or other folder) and this process didn't stop. Last time we have this situation - our monitoring system shows unusual amount of imap traffic send to one of local hosts. This host was - terminal server and 20 users worked with their mailboxes that time. But normal 20 imap session can't fork that amount of traffic (5.2Gb). After measuring local thunderbird's cached mailboxes we find out that one user have local INBOX about 19Gb and size is rising. On server side - this mailbox was 89Mb. And after killing thunderbird in logs appear: Dec 10 17:35:53 IMAP(user@domain 192.168.2.92): Info: Disconnected: Logged out bytes=1133593/1175103 Dec 10 17:35:53 IMAP(user@domain 192.168.2.92): Info: Disconnected: Logged out bytes=15964/44364 Dec 10 17:35:53 IMAP(user@domain 192.168.2.92): Info: Disconnected: Logged out bytes=54758/944989 Dec 10 17:35:53 IMAP(user@domain 192.168.2.92): Info: Disconnected: Logged out bytes=6532/43930 Dec 10 17:35:53 IMAP(domain@domain 192.168.2.92): Info: Connection closed bytes=235408/4797272694 As you can see - 4.8Gb of data was send to this client - and who knows - what was that. So we have 5.2Gb send to host with 20 active sessions and 4.8Gb send to one user. Of course lifetime of this connection can be much more than last day, but problem disappeared after killing it. This is not single accident. But this one was hard to find out because of 20-25 users working at the same time from 1 server. So it will be great if dovecot has feature to limit the amount of data send per connection. For example: service imap { bytes_per_connection = 100Mb } And after limit reached - close connection and log warning. This will much simplify fights with sometimes become crazy imap clients. That do you think?

[Dovecot] Quota warning generated when crossing on both sides
by Harm van Tilborg 13 Dec '10

13 Dec '10

Hello everyone, I'm experimenting with the quota warning plugin. I have the following setting in Dovecot's general config: plugin { quota_warning = storage=75%% /var/www/contrib/doquotawarning.py 75 quota_warning2 = storage=90%% /var/www/contrib/doquotawarning.py 90 } The doquotawarning.py script is working okay -- meaning that the user gets a warning. My SQL backend uses the following query: user_query = \ SELECT m.maildir AS home, 1001 AS uid, 1001 AS gid, \ CONCAT('*:bytes=', m.quota, 'M') AS quota_rule, \ 'Trash:ignore' AS quota_rule2 \ FROM mailbox m \ INNER JOIN domain d \ ON d.id = m.domainid \ WHERE d.domain = '%d' \ AND m.user = '%n' Where m.quota is the user's personal quota (in MB). As you can see, we ignore the 'Trash' box, when considering the usage data. We are using the dict quota backend. Now this is what happens. Assume we have 'user(a)example.org', that has a quota of 10MB and he currently has 5MB in use. Now someone sends a 3MB email towards 'user(a)example.org'. Dovecot does indeed generate the warning message (75%), that arrives correctly 'together' with the 3MB email. Now the user moves the 3MB email to trash. This goes well, however: Dovecot generates the 75% warning message again. Which is not necessary: the user was cleaning his mailbox, i.e. usage is 5MB again. I have the feeling Dovecot is generating the warning event twice. When getting from e.g. 50% to 79% and when the usage is lowered from 87% to 70%. I have the feeling this is either not the correct behavior, or I'm misinformed. When looking at the source, this shouldn't be happening: if ((bytes_before < (uint64_t)warnings[i].rule.bytes_limit && bytes_current >= (uint64_t)warnings[i].rule.bytes_limit) || (count_before < (uint64_t)warnings[i].rule.count_limit && count_current >= (uint64_t)warnings[i].rule.count_limit)) { quota_warning_execute(root, warnings[i].command); break; } We're using Dovecot 1.2.9 (Ubuntu's 10.04 LTS version). -- Kind regards, Harm van Tilborg

[Dovecot] Crash in 2.0.8 dovecot/imap - information capture

13 Dec '10

My dovecot logs revealed a crash in the dovecot/imap process a few days ago. It appears to have dereferenced 0x00000004 in the storage shared lib. Unfortunately, I didn't get a core and I'm not sure how to reproduce it. Dovecot 2.0.8 on linux32. Two questions: 1) How can I be sure I get a core next time? I think it's because I run dovecot/imap under a mail uid and didn't have write permission to the cwd. Any way to verify that was it, and be sure it works? 2) What other settings would provide more info if it happens again?

[Dovecot] director_user_expire
by Cor Bosman 11 Dec '10

11 Dec '10

Would it be ok to set director_user_expire to a very high value? Say 1 day? This would pretty much lock a user into a specific server right? What if I set it to 1 year? :) What happens when the server a user is locked into disappears (i remove it from the pool). Then a day later, I add the server again. Is the user now locked to the new server, or will he revert back to the old server? Cor

[Dovecot] Execute Script on LMTP Deliver?
by Edward Carraro 10 Dec '10

10 Dec '10

Is it possible to have dovecot 2.0.8 using LMTP run a shell script each time it delivers a message to a users mailbox? I see there's an "execute = script /path/to/script" but when i added it to lmtp service in 10-master.conf, it didnt do anything and stopped delivering mail altogether service lmtp { executable = script /usr/local/bin/test.sh u% unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix user = postfix } inet_listener lmtp { port = 24 } } $ ls -lh | grep test -rwxrwxrwx 1 root staff 270 2010-12-09 18:05 test.sh $ cat test.sh #!/bin/sh USER=$1 echo $USER > /tmp/newfile basically when a message arrives, it will execute a shellscript which will notify another service that mail has arrived in their inbox

[Dovecot] Phantom INBOX in 1.2. Is there a stable .deb of 2.0?
by ian+dovecot＠comtek.co.uk 10 Dec '10

10 Dec '10

Hi, We've been running 1.2 Dovecot for a while and are happy with it. In trying to migrate from symlinks to shared folders I see a similar problem to that shown at http://www.mail-archive.com/dovecot@dovecot.org/msg32083.html . For example: . lsub "" "*" * LSUB () "." "Users..INBOX" The advice given in the thread is to upgrade to 2.0. We currently use Debian's 1.2 package and I'm reluctant to move since I can't find a stable 2.0 .deb (http://wiki2.dovecot.org/PrebuiltBinaries only has repository heads of 2.0). Building from source is an option but I'd really prefer to be using a package. Can anybody advise on an appropriate way to go? Like the original poster I am seeing INBOX under the shared namespace when I try to share. I'm also getting an empty /var/mail/virtual/users/Maildir created (maildir:/var/mail/virtual/users/%n/Maildir/). We formerly had an INBOX prefix namespace from a Courier migration too, but it has been deleted (to no avail). Shared folders do work, though. It just requires 'anyone l' in /etc/dovecot/dovecot-acls/.DEFAULT (though I'd really rather not do this!). Thanks for any help, Ian ######## mail_location = maildir:/var/mail/virtual/users/%n/Maildir/ namespace private { separator = . prefix = inbox = yes } namespace shared { separator = . prefix = Users.%%n. location = maildir:/var/mail/virtual/users/%%n/Maildir/:INDEX=~/shared/%%u subscriptions = no list = children } namespace public { separator = . prefix = Shared. location = maildir:/var/mail/virtual/public:INDEX=~/public subscriptions = no } auth default { mechanisms = plain passdb ldap { args = /etc/dovecot/dovecot-ldap.conf } passdb ldap { args = /etc/dovecot/dovecot-ldap-master.conf master=yes } userdb passwd { } userdb ldap { args = /etc/dovecot/dovecot-ldap-userdb.conf } userdb ldap { args = /etc/dovecot/dovecot-shared-ldap.conf } } plugin { acl = vfile:/etc/dovecot/dovecot-acls:cache_secs=3 acl_shared_dict = file:/var/mail/virtual/shared-mailboxes.db }

[Dovecot] Released Pigeonhole v0.2.2 for Dovecot v2.0.8
by Stephan Bosch 10 Dec '10

10 Dec '10

Hello Dovecot users, The new Dovecot v2.0.8 release has a few changes that prompted changes in Pigeonhole as well. This means that a new release of Pigeonhole is also necessary, because otherwise things will not compile anymore. Apart from a few rather minor bugfixes, some of which originate in Dovecot, one TODO item has finally been resolved: the reject action uses the LDA mail reject API, meaning that the associated LDA settings now also work for Pigeonhole, as would be expected. Changelog v0.2.2: * LDA Sieve plugin: started using Dovecot LDA reject API for the reject extension. This means that the LDA reject_reason and reject_subject settings now also work for Pigeonhole's LDA Sieve plugin. * Did some work on the new sieve-filter tool. It is mostly functional, but it is not finished yet. * Dovecot change: services' default vsz_limits weren't being enforced correctly in earlier v2.0 releases. Now that they are enforced, you might notice that the default limits are too low and you need to increase them. This problem will show up in logs as "out of memory" errors. See default_vsz_limit and service { vsz_limit } settings. - Imap4flags: fixed segfault bug occurring in multiscript context. - Added version checking to the ManageSieve settings plugin. This plugin was forgotten when the LDA plugin was updated with this change in the previous release. - LDA Sieve plugin: fixed memory leak at deinitialization. The release is available as follows: http://www.rename-it.nl/dovecot/2.0/dovecot-2.0-pigeonhole-0.2.2.tar.gz http://www.rename-it.nl/dovecot/2.0/dovecot-2.0-pigeonhole-0.2.2.tar.gz.sig Refer to http://pigeonhole.dovecot.org and the Dovecot v2.0 wiki for more information. Have fun testing this new release and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

[Dovecot] Dovecot as IMAP proxy to Exchange
by Hugo Monteiro 09 Dec '10

09 Dec '10

Hello list, I'm looking into the possibility to setup dovecot to act as an IMAP proxy to an Exchange server. Things i know beforehand: - I will not be able to use the ldap (Active Directory) user DN for auth binds (but i discovered that i could could use the user userPrincipalName attribute as bind DN. I tested it using ldapsearch and it worked fine.) - I will not be able to perform any unbinded searches. - The Exchange server is unique, so i can setup a static proxy route to the server. Given the above, i'd like to post some questions: 1 - Will i be able to use auth_bind = yes given the restrictions? My first guess is that this might work if i use something like "auth_bind_userdn = %u(a)example.org" 2 - Will i be able to specify a static route to the exchange server, not having to rely on that information from the AD itself? Another thing i'd like to know is if NTLM auth can be used while dovecot acts only as proxy.

[Dovecot] Dovecot 1.2/2.0 coexistence guide?
by Tom Talpey 09 Dec '10

09 Dec '10

I am running Dovecot 1.2.16 and considering moving up to 2.0.8. I have found <http://wiki2.dovecot.org/Upgrading/2.0> but there's not a lot about deploying a 2.0 server alongside an existing 1.2. Any hints on a seamless approach to this, especially one that might allow me to upgrade individual users in place, without moving their maildirs into a new tree and still avoid issues with 1.2/2.0 sharing access?

[Dovecot] How to handle "Waiting for authentication process..."

Sometimes, when dovecot authentication processes are busy, dovecot write reply "Waiting for authentication process to respond.." to client. Roundcube webmail do not understand it and invalidate user session. My question is what is a good practise to handle this situation by client software? One Roundcube user proposes to detect such response then wait a moment and try again. Is there any standard for this? How long should we wait?

[Dovecot] local seen flags with shared mailboxes

08 Dec '10

Hello all, after recent upgrade from 2.0.5 to 2.0.8 it seems that local seen flags for mails reside in shared mailboxes doesn´t work anymore. Before the upgrade I had read mails with account #1. Account #2 (who has access via acl) saw the mails still as unread. Now, no matter who read the mails, the other account see the same flags, immediately. I read the related wiki pages again and tried to find any configuration error, unfortunately without much success. I´ve attached output from "doveconf -n" and a debug logfile. Thanks a lot! Tim

As I mentioned in another post, your log message clearly shows the IPv6 address is being used. And yes, your host obviously is capable of that. You don't need to specifically enable it with fetchmail. It will under certain circumstances default to IPv6, which in your case happened. As also mentioned, your postfix seems to not bind to the IPv6 address by default, though, or it has deliberately been disabled. Moreover, your router is not even in the picture here -- just like dovecot, FWIW. Fetchmail fetches the mail from a remote server, and tries to deliver it locally. That local delivery step is generating the log messages. A mail, sent from and to your box. Long after the data stream passed your router...

[Dovecot] imap/pop proxy and filter

Hi I use dovecot as imap/pop proxy. Is it possible to filter the messages before they get delivered to the client? Thanks for any hint how to achieve this. Mike

[Dovecot] proxy and gpg processing
by Mike 07 Dec '10

07 Dec '10

Hi I have dovecot running as pure proxy for accessing imap and pop mailboxes on other servers. How can I do the following scenario: When a client user reads a gpg signed or gpg encrypted email through the proxy, can I verify/decrypt the email before it gets delivered to the client user? Ideally I would like to write a perl program which processes the email within the proxy before it gets delivered to the user. With Sieve I can not do this, is there another way to achieve this? Thanks for any hint. Mike

Can I use Sieve for mail filtering despite I do not have local mailboxes? Thanks, Mike

[Dovecot] imap limits please ?
by Spyros Tsiolis 06 Dec '10

06 Dec '10

Hello, Finally managed to sync an outlook client to dovecot. Looks like it's working. Questions though ; : What are the limits? Number of Folders ? Number of mails per folder ? E.g. for a client of mine, I know that she uses about 5Gb of data at the moment (and counting). Now, this same outlook client consists of the following : 1. about thirty (30) folders ranging from 1000 messages per folder to 100 messages per folder 2. A "Sent Items" folder with about 4,000 messages (and counting) 3. A "Deleted Items" folder with about 5,500 messages (and counting) System, now, is a CentOS 5.5 32-bit on an hp/compaq dl360 (G3) with RAID1 76,3Gb Disks UW320 and four (4Gb) of RAM Output of "dovecot -n" : ------------------------------------------------------------ # 1.2.16: /etc/dovecot/dovecot.conf # OS: Linux 2.6.18-194.17.4.el5 i686 CentOS release 5.5 (Final) ext3 base_dir: /var/run/dovecot/ log_path: /var/log/dovecot/dovecot.log info_log_path: /var/log/dovecot/dovecot-info.log ssl_parameters_regenerate: 48 verbose_ssl: yes login_dir: /var/run/dovecot//login login_executable: /usr/local/dovecot/libexec/dovecot/imap-login login_greeting: * Dovecot ready * login_max_processes_count: 32 mail_location: maildir:/var/MailRoot/domains/%d/%n/Maildir mail_plugins: zlib auth default: verbose: yes debug: yes debug_passwords: yes passdb: driver: passwd-file args: /etc/dovecot/passwd passdb: driver: pam userdb: driver: static args: uid=vmail gid=vmail home=/home/vmail/%u userdb: driver: passwd ------------------------------------------------------------ Any answer would be greatly appreciated since I am trying to know the systems' limits.

[Dovecot] CentOS 5 + selinux
by Marcelo Roccasalva 06 Dec '10

06 Dec '10

I've just installed CentOS 5.5 and dovecot 2.0.7. Out of the box, it worked ok with local user accounts. Then I enable selinux and I could no loger login to imap server. I can deal with that via a local policy. But I found dovecot tried to open /etc/shadow: type=AVC msg=audit(1291490764.101:670): avc: denied { read } for pid=16130 comm="auth" name="shadow" dev=md2 ino=96335 scontext=user_u:system_r:dovecot_t:s0 tcontext=system_u:object_r:shadow_t:s0 tclass=file type=AVC msg=audit(1291500097.318:818): avc: denied { getattr } for pid=17350 comm="auth" path="/etc/shadow" dev=md2 ino=95396 scontext=user_u:system_r:dovecot_t:s0 tcontext=system_u:object_r:shadow_t:s0 tclass=file even it is configured for pam passdb: # dovecot -n # 2.0.7: /etc/dovecot/dovecot.conf # OS: Linux 2.6.18-194.26.1.el5 x86_64 CentOS release 5.5 (Final) mbox_write_locks = fcntl passdb { driver = pam } ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { driver = passwd } I straced the process and it efectively tries to open /etc/shadow. I don't want to disable selinux but I'm not happy letting dovecot read my /etc/shadow. Is there a guide to selinux and dovecot? -- Marcelo "¿No será acaso que ésta vida moderna está teniendo más de moderna que de vida?" (Mafalda)

[Dovecot] 1.2.15 - segfault if host field attribute not present in ldap. (proxy)
by Mohit Chawla 06 Dec '10

06 Dec '10

In case this is relevant: kernel: [17549.714369] imap-login[11704]: segfault at 0 ip b75c3d23 sp bf888178 error 4 in libc-2.11.2.so[b7551000+140000] If no host field attribute is present in ldap (like mailHost for qmail-ldap), and we are trying to use proxy, then dovecot segfaults. If more information's needed, let me know. Also, somewhat unrelated, but maybe the wiki needs to be edited since using a template as =proxy_maybe=y works, while in wiki its kinda opposite. I don't know of specifics, but should I try using a recent release ?

[Dovecot] Problem with ACLs
by Micha Krause 06 Dec '10

06 Dec '10

Hi, i want to use unix groups in my ACLs. http://wiki2.dovecot.org/ACL says, I can do that with a post-login script (http://wiki2.dovecot.org/PostLoginScripting) I have verified, that the script is running, and that ACL_GROUPS is correct. But I still can't access the Mailbox. Logfile says: Dec 3 11:19:35 mailint1 dovecot: imap(micha): Debug: acl vfile: reading file /var/mail/mailboxes/shared/mails/server-root/dovecot-acl Dec 3 11:19:35 mailint1 dovecot: imap(micha): Debug: acl vfile: reading file /var/mail/mailboxes/shared/mails/dovecot-acl Im using: dovecot 2.0.7 (5e82c5b1b4a9) Micha Krause

[Dovecot] Internal Error form delivery from LDAP lookup.
by Jorgen Lundman 06 Dec '10

06 Dec '10

Solaris-x86-10u8 Dovecot-1.2.7 Large mail setup, with quite a few MX servers working well. Generally everything is super. But every now and then, we get "bouts of bad weather" - which only lasts a short time, and curiously nearly always occur when mail is sent to customer mailing lists. I suspect mostly because of that 1 message has multiple recipients within the same domain. Perhaps. Delivery setup as: main.cf: virtual_transport = dovecot dovecot_destination_recipient_limit = 1 dovecot_destination_concurrency_limit=300 master.cf: dovecot unix - n n - 70 pipe flags=DRhu user=dovecot:dovecot argv=/usr/local/libexec/dovecot/deliver -f ${sender} -d ${recipient} Errors look something like: example.com Dec 06 08:46:25 deliver(rbc-005(a)example.com): Info: msgid=<A22A602A940A45A49EA2C4CC53D27655(a)UQC.local>: saved mail to INBOX Dec 06 08:46:25 deliver(rbc-002(a)example.com): Info: msgid=<A22A602A940A45A49EA2C4CC53D27655(a)UQC.local>: saved mail to INBOX Dec 06 08:46:28 deliver(rbc-004(a)example.com): Error: userdb lookup(rbc-004(a)example.com) failed: Internal failure Dec 06 08:46:28 deliver(rbc-011(a)example.com): Error: userdb lookup(rbc-011(a)example.com) failed: Internal failure Dec 06 08:46:28 deliver(rbc-013(a)example.com): Error: userdb lookup(rbc-013(a)example.com) failed: Internal failure Dec 06 08:46:28 deliver(rbc-006(a)example.com): Error: userdb lookup(rbc-006(a)example.com) failed: Internal failure Later on, when it retries, everything goes according to plan and delivery is achieved. Now this is actually due to slapd saying: Dec 6 08:46:25 vmx15.unix slapd[3958]: [ID 763815 local4.debug] connection_input: conn=72057 deferring operation: too many executing And since it happens most frequently with mailing-lists, or mails with many recipients, I would guess it is due to a large number of lookups happening in a very short time. Since dovecot_destination_recipient_limit=1, I believe 'deliver' is only ever called with just one recipient for "-d", and 'deliver' probably-does-not (?) query LDAP for any of the other "To:" addresses in the message body. Is that the case? Secondary, the dovecot-ldap.conf for dovecot-auth has: hosts = 127.0.0.1 172.20.12.33 172.20.12.23 172.20.12.113 So even though localhost's slapd was busy at the time, the other three hosts were definitely not. Is LDAP fail-over ... failing... in this case? How many concurrent queries does dovecot-auth perform? Any way to tweak this value? Admittedly, postfix/dovecot does handle this situation correctly, as 'temporary failure' and mail delivery is merely delayed. But at the same time, it *could* be something with an easy fix as well.

What exactly is the error message? Is it always the same specific user, or if you reorder users is it always the 150th?

[Dovecot] Dovecot v2.1 plans
by Timo Sirainen 06 Dec '10

06 Dec '10

Now that v2.0 seems to be getting stable, I finally started v2.1 branch: http://hg.dovecot.org/dovecot-2.1/ So far there are just some API changes to fix some annoyances and to make it simpler. They'll probably keep coming for a while more to make future work easier. As for larger upcoming features, I'm hoping for: - simplify index files and make it write only via lib-fs (but keep backwards compatibility & make v2.0 forwards compatible) - make lib-storage API support asynchronous and support parallel lookups - use async disk io as much as possible & get rid of all lock waits inside lib-storage -> it'll be ok to have lots of imap/pop3 connections per process, at least for some storage backends - write imap-client lib-storage backend (make it fast using above async stuff - using configurable number of IMAP connections) - this could maybe also be used to access other users' shared mailboxes when it can't be done directly - design a mailbox format (maybe based on dbox) for key-value databases, implement it via lib-fs and implement a lib-fs backend for one such database - merge Apple's CATENATE and URLAUTH patch But if some company desperately wants me to work on other stuff, that list can change. BTW. I'm moving back to Finland in two weeks. Maybe I'll also get some studying done towards my Master's degree. :)

[Dovecot] 2.0.8 & enable-header-install
by Tamsy 05 Dec '10

Dear List, up to Dovecot 2.07 I used "--enable-header-install" for the Sieve Plugin when configuring Dovecot before compiling. With 2.0.8 I get the following message when running the configure script: "configure: WARNING: unrecognized options: --enable-header-install" Is this intentionally? Is there a substitute directive for Sieve when compiling Dovecot 2.08? Rgds Tamsy

[Dovecot] v2.0.8 released
by Timo Sirainen 03 Dec '10

03 Dec '10

http://dovecot.org/releases/2.0/dovecot-2.0.8.tar.gz http://dovecot.org/releases/2.0/dovecot-2.0.8.tar.gz.sig There are many small fixes all around, plus some more noticeable changes: * Services' default vsz_limits weren't being enforced correctly in earlier v2.0 releases. Now that they are enforced, you might notice that the default limits are too low and you need to increase them. This problem will show up in logs as "out of memory" errors. See default_vsz_limit and service { vsz_limit } settings. * LMTP: In earlier versions if mail was delivered to user+detail@domain address, LMTP server always attempted to deliver the mail to mailbox named "detail". This was rather unintentional and shouldn't have been the default. lmtp_save_to_detail_mailbox=yes setting now preserves this behavior (default is no). + Added systemd support (configure --with-systemdsystemunitdir). Based on patch by Christophe Fergeau. + Replaced broken mbox-snarf plugin with a new more generic snarf plugin. - dbox: Fixes to handling external mail attachments - verbose_proctitle=yes didn't work for all processes in v2.0.7 - imap, pop3: When service { client_count } was larger than 1, the log messages didn't use the correct prefix. Last logged in user's prefix was always used, regardless of what user's session actually logged it. Now the proper log prefix is always used. - MySQL: Only the first specified host was ever used

[Dovecot] Indexes.
by Henrique Fernandes 03 Dec '10

03 Dec '10

Hello people! I have huge problems with IO wait becase dovecot configured to use maildir is under OCFS2 1.4. Now i have an question to OCFS2 each disk action is really heavy becaue it has no index. Now i am thinking in what can be done to heltp my system to use less disk. Looking for index and etc in dovecot i found this, this disables the index file on disk and leave it on ram or it disable the index files ? If you really want to, you can also disable the index files completely by appending :INDEX=MEMORY I am only trying to get dovecot to work faster. Right now we have to waing some seconds to dovecot list all emails or read an email. I am also thinking in right index to an NFS but i don't know if this makes any diferences in performance. Thanks to all! I use 3 servres wrinting on OCFS2 one is mailman, and other two are to email, I have ipvs to load balance the conections. []'sf.rique

Hello to all, I am setting up a mail server using sendmail and dovecot 2.0.7 with maildir storage. I want to use dovecot lmtp as local mail delivery agent becouse when I send a message to multiple recipients it deliver the message to all recipients with hard links instead of store n copies of the message. The only think I can't set up is make dovecot-lmtp reading the .forward file in the user's home directory. I think I am missing something, becouse dovecot-lda read that file but don't do hard links when deliver the mail. What I am missing?

[Dovecot] SSL issues on separate IPs
by Tim Traver 03 Dec '10

03 Dec '10

Hi Timo, I have set up 2.07 to answer on several different IP's with different SSL certs, like the following : local 209.132.xx.4 { ssl_cert = </shared/templates/res/1040/certs/*.xxxxx.com.crt-pem-298 ssl_key = </shared/templates/res/1040/certs/*.xxxxx.com.key-298 } I have several of these, and there appears to be a problem with one in particular that is dropping connections, and I'm not sure why. In this case it is a wildcard cert issued from godaddy, and I have the cert file in pem format with the chain on it. I have another completely separate local IP setup with a different cert on it that works without any problems. This particular one drops the connection when I try to connect to IMAP using TLS on port 143, or using the IMAP SSL port of 993. When I try it using Thunderbird, I am using the default settings for both tests. The Thunderbird error I get is "The server has disconnected. The server may have gone down or there may be a network problem." I don't see any errors in the dovecot error log or the system error log, and when using doveadm who to view the current connections, it does not show a connection. I tried enabling the logs for SSL errors, but nothing appears for my IP when attempting to connect. FreeBSD 8.1 with openssl 0.9.8n. The IP's are on the box and are on the loopback interface if that makes any difference for a direct server return load balancing system. But, I don't know how that would make a difference since one of the separated IP's works with its cert, and the other one disconnects. Thanks, Tim.

[Dovecot] Static userdb with LDAP passdb but without "allow_all_users=yes"?
by Andreas Ntaflos 03 Dec '10

03 Dec '10

Hi, Is it possible to have a static user database along with an LDAP password database and *not* be forced to set "allow_all_users=yes" for the userdb? The wiki page on static user database says "Normally static userdb handles this by doing a passdb lookup instead." How should the passdb behave in order for this to work? In my tests (on a test server) I am using Dovecot 2.0.7 and Postfix 2.7.0 on Ubuntu 10.04.1. I use (or am trying to use) LMTP with Dovecot and Postfix according to the HOWTO in the wiki [1] as well as dynamic address verification with LMTP [2]. Users are virtual, using a static userdb and passwords from LDAP. I also serve local system users which is why I also have userdb and passdb pam, but this isn't the issue here. Delivering mail to an existing virtual user works fine as far as I can see but when a non-existent user is the recipient Dovecot complains that the passdb doesn't support lookups: postfix/smtpd[26469]: connect from remote-smtp.example.net[10.0.0.10] postfix/cleanup[26474]: 772A760B25: message- id=<20101125172409.772A760B25(a)mailtest.example.com> postfix/qmgr[27672]: 772A760B25: from=<double- bounce(a)mailtest.example.com>, size=276, nrcpt=1 (queue active) dovecot: lmtp(22109): Connect from local dovecot: auth: Error: static(not-a-user(a)test01.example.com): passdb doesn't support lookups, can't verify user's existence dovecot: lmtp(22109): Error: user not-a-user(a)test01.example.com: Auth USER lookup failed dovecot: lmtp(22109): Disconnect from local: Client quit postfix/lmtp[26475]: 772A760B25: to=<not-a-user(a)test01.example.com>, relay=mailtest.example.com[private/dovecot-lmtp], delay=0.18, delays=0.17/0.01/0/0, dsn=4.3.0, status=undeliverable (host mailtest.example.com[private/dovecot-lmtp] said: 451 4.3.0 <not-a- user(a)test01.example.com> Internal error occurred.

To summarise: I want to use LMTP, dynamic address verification, a static user database and an LDAP password database.

The best fix for this is to prevent it from happening. Configure your setup so that a user always gets redirected to the same server (unless it's down). This also means that mail deliveries must be done by the same server, or alternatively it shouldn't update index files. Dovecot flushes NFS caches when needed if you set mail_nfs_storage=yes, but unfortunately this doesn't work 100%, so you can get random errors. Disabling NFS attribute cache helps a lot in getting rid of caching related errors, but this makes the performance MUCH worse and increases the load on NFS server. This can usually be done by giving actimeo=0 or noac mount option. Index files As described above, it's better to redirect users to the same server whenever possible. If you do this, it might also be a good idea to keep index files stored locally in that server. If user gets occasionally redirected to another server, the indexes will then be created locally there. This isn't a problem. However you might want to create a cronjob to delete old index directories. If you choose to keep the index files stored in NFS, you'll need to set mmap_disable=yes. Both the mmap_disable and indexing to NFS will result in a notable performance hit. If you're not running lockd you'll have to set lock_method=dotlock, but this degrades performance. Note that many NFS installations have problems with lockd. If you're beginning to get all kinds of locking related errors, try if the problems go away with dotlocking. ------------- but i agree, there should be more info with cluster file systems in the wiki perhaps Timo has time to send recommands by mail, i am not sure that mine are optimal ( whatever i have no problems yet ) > > > I will try send an image on the load of machine. > > > []'sf.rique > > > On Thu, Dec 2, 2010 at 11:25 AM, Robert Schetterer > <robert(a)schetterer.org <mailto:robert@schetterer.org>> wrote: > > Am 02.12.2010 14:10, schrieb Henrique Fernandes: > > With recomendation settings do you have ? > > http://wiki2.dovecot.org/MailLocation/SharedDisk > > and a few more optimizes about maildir > > > > how many clients ? > > i started the server not long ago so they are less yet ( about 100 > maildirs ) > but i have my own account in it which has massive mails ( 10 GB store > with over 1000 mails daily in out , and perhaps 10000 mails in store) > > > > > sorry, i did not say i use dovecot 2.0.6 > > looks fine, update to 2.0.8 if ready > > > did you use the mail option at ocfs2 store creation ? > > what os/distro do you use , i remember bugs with ocfs with some distro > versions > > > > > []'sf.rique > > > > > > On Thu, Dec 2, 2010 at 10:40 AM, Robert Schetterer > > <robert(a)schetterer.org <mailto:robert@schetterer.org> > <mailto:robert@schetterer.org <mailto:robert@schetterer.org>>> wrote: > > > > Am 02.12.2010 13:13, schrieb Henrique Fernandes: > > > Hello people! > > > > > > I have huge problems with IO wait becase dovecot configured > to use > > maildir > > > is under OCFS2 1.4.

[Dovecot] Virtual folder root cannot be opened, virtual folders ok
by Tom Talpey 02 Dec '10

02 Dec '10

I am running dovecot 1.2.16 and not able to figure out an error that happens whenever I select the root of a virtual mailbox tree. At the moment I have a simple maildir store, accessed via IMAP, and have successfully added a virtual fs namespace with two subdirectories. I have created dovecot-virtual entries in the subdirs and they are working fine; they show the expected messages, etc. My problem is with the top-level virtual directory. If I happen to select it in Thunderbird (Eudora, actually), I receive a popup "The current command did not succeed. The mail server responded:Mailbox doesn't exist: Mobile." It also fails in the same way during search, which interrupts it and makes other client operations fail. I have tried placing a dovecot-virtual rule in the directory, leaving the directory empty, moving it in or out of the maildir tree, tweaking namespace and INDEX/LAYOUT options all with the same result - the subdirs are fine, the virtual root fails. I must be missing something obvious. Clue, please? Thanks!

[Dovecot] Virtual mailboxes and subfolders
by François-Xavier Payet 02 Dec '10

02 Dec '10

Hello again, I'd like to know if there is a way to have subfolders in virtual mailbox? In my virtual namespaces, I have some virtual maiboxes named like this : Mailbox Mailbox.SubMailbox (the separator is '.') But when I try to access the submailbox, depending on my client, it either : - Tells me the mailbox doesn't exists (Roundcube) - Don't show me any error, but don't display any mail in the mailbox (Apple Mail.app) So I'd like to know if this is because I can't make subfolders of virtual mailboxes, or if I'm doing something wrong. Thanks.

[Dovecot] Have inbox at the same place
by Spyros Tsiolis 02 Dec '10

02 Dec '10

Hello again, I have an installation with dovecot and I am accessing it through linux mint and thunderbird v3.0.10 As thunderbird "subscribes" to dovecot, it does the following : Inbox Trash MyName(a)Mydomain.gr Local Folders Local Folders MyName(a)Mydomain.gr subfolder A Subfolder B Subfolder C Subfolder D Subfolder E Local Folders Outbox OK, I have to admit a have a couple of folders more than what I need. But this is fine. My problem is that *everything* is in its respective place (say, *all* subfolders have their respective e-mail properly laid in there), but the messages I keep on the inbox is the "Inbox" folder. What I would like to have is my Inbox messages under (or *on*) MyName(a)Mydomain.gr folder. Also, trash mail goes to : Trash MyName(a)Mydomain.gr folder. Could this also be under the more generic MyName(a)Mydomain.gr folder further down the tree ? (Hope you understand this :-) The tree above is represented exactly as it looks like on thunderbird (with the indentations and everthing). The "dovecot -n" output follows : ------------------------------------------------------------------- # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.18-194.17.1.el5PAE i686 CentOS release 5.5 (Final) ext3 base_dir: /var/run/dovecot/ log_path: /var/log/dovecot/dovecot.log info_log_path: /var/log/dovecot/dovecot-info.log ssl: required ssl_parameters_regenerate: 48 verbose_ssl: yes login_dir: /var/run/dovecot//login login_executable: /usr/local/dovecot/libexec/dovecot/imap-login login_greeting: * Dovecot ready * login_max_processes_count: 32 mail_location: maildir:/var/MailRoot/domains/%d/%n/Maildir mail_plugins: zlib auth default: verbose: yes debug: yes debug_passwords: yes passdb: driver: passwd-file args: /etc/dovecot/passwd passdb: driver: pam userdb: driver: static args: uid=vmail gid=vmail home=/home/vmail/%u userdb: driver: passwd ------------------------------------------------------------------- Is this possible ?

Greetings yesterday i was resetting an account from a script. and the user was deleted an re-added. subsequently the user now has two dovecot directories.

[Dovecot] Permission denied error log messages
by Tim Traver 02 Dec '10

02 Dec '10

Hi Timo, ok, I have a large 2.07 NFS setup, and I have been monitoring error messages to make sure I catch things, and I've come across a lot of messages that come in pairs and look like this : Dec 01 17:48:35 lda(paul(a)xxxxxx.com): Error: write(/home/mailboxes/data/301/paul@xxxxxx.com/Maildir/tmp/1291254514.M620308P83269.mta2.scaledsystems.com) failed: Permission denied Dec 01 17:48:35 lda(paul(a)xxxxxx.com): Error: sieve: msgid=unspecified: failed to store into mailbox 'INBOX': Internal error occurred. Refer to server log for more information. [2010-12-01 17:48:34] I run the dovecot installation as a single user, and that user owns ALL of my virtual accounts directories. I checked, and there aren't any permissions that aren't correct. All the way up the tree has the same owner and group, and there are plenty of messages that make it through without any issue. The NFS servers don't have enough load on them to return errors for file operations, so I don't believe it is that. We use high end NetApp equipment and have never had any problems with them. I'm baffled as to why it gets permission denied message on the tmp directory. There does not seem to be a recognizable pattern for times, or particular accounts. I've just got a heck of a lot of these messages in the deliver log error files... I use qmail control files to feed the lda delivery for messages. When these errors happen, is the message lost? or is it still queued up in qmail's queue when the lda gives a fatal error like that? Thanks, Tim. here is my dovecot -n output : # 2.0.7: /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 8.0-RELEASE-p3 i386 auth_username_format = %Lu auth_username_translation = %@ auth_verbose = yes disable_plaintext_auth = no dotlock_use_excl = yes first_valid_uid = 100 listen = * lock_method = dotlock log_path = /local/logs/dovecot.errors mail_fsync = always mail_gid = 100 mail_location = maildir:%h/Maildir mail_nfs_index = yes mail_nfs_storage = yes mail_plugins = " quota" mail_uid = 100 managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date imapflags notify mmap_disable = yes passdb { args = /bin/checkpassword_dovecot_auth driver = checkpassword } plugin { quota = maildir:User quota quota_rule = Trash:storage=+100M sieve = ~/.dovecot.sieve sieve_after = /home/mailboxes/sieve/to_spam_folder.sieve sieve_dir = ~/Maildir/sieve sieve_extensions = +notify +imapflags } protocols = imap pop3 sieve service auth { unix_listener auth-userdb { group = sn mode = 0600 user = sn } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = prefetch } userdb { args = /bin/checkpassword_dovecot_deliver driver = checkpassword } verbose_proctitle = yes protocol pop3 { pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } protocol lda { info_log_path = /local/logs/dovecot-deliver.log log_path = /local/logs/dovecot-deliver-errors.log mail_plugins = " quota sieve" } protocol imap { mail_plugins = " quota imap_quota" } protocol sieve { managesieve_sieve_capability = comparator-i;ascii-numeric fileinto reject vacation imap4flags notify include envelope body relational regex subaddress copy }

Hi, I'm sorry if this is a silly question, but i know that is not possible in Courier, so, I need to check if I can do it with Dovecot. Can I use PAM authentication, witch get the users data from a external database (like mysql)? I've found many ways to do this stuff disconnectedly (like pam authentication with passwd ), but i can put all together? I can't use the passwd... Thank's, Álvaro

[Dovecot] How to know if dovecot director is running OK?
by Antonio Perez-Aranda 30 Nov '10

30 Nov '10

I'm using director on dovecot 2.0 At present, I know that two instances are connected, If I stop of one system, then I can watch how to the connections are closed on port 5000. I defined 5000 as director port. I have one user (user1) connected to kvm1 (192.168.13.100) and kvm2 (192.168.13.101) servers vía telnet telnet kvm1 143 and then login telnet kvm2 143 and then login If try to execute doveadm director status I can watch the two server like that: [root@kvm1 ~]# doveadm director status mail server ip vhosts users 192.168.13.100 100 0 192.168.13.101 100 0 If I try to find if a server has been asigned to user, but I don't know if it is running correctly [root@kvm1 ~]# doveadm director status user1 Current: not assigned Hashed: 192.168.13.101 Initial config: 192.168.13.101 [root@kvm2 ~]# doveadm director status user1 Current: not assigned Hashed: 192.168.13.101 Initial config: 192.168.13.101 Is there any way to test if it really running?

[Dovecot] "doveadm auth user" requiring a tty
by Axel Luttgens 30 Nov '10

30 Nov '10

Hello, "doveadm auth user password" may be scripted without a glitch. But this comes with the usual problem of a "ps" command showing the password, which may be especially annoying in case of a single-letter typo: the almost correct password is then visible for about two seconds... Clearing the password argument (zeroing it) in doveadm-auth.c, in the hope to reduce the window during which the password may be catched, didn't prove successful. "doveadm auth user" could be an alternative, but it imperatively requires a tty, which may not always easily nor efficiently be available in a scripting environment. I thus ended with this very quick and dirty hack (I guess this should be named that way): --- askpass.original.c 2010-05-31 18:36:52.000000000 +0200 +++ askpass.c 2010-11-27 19:12:03.000000000 +0100 @@ -16,8 +16,24 @@ char ch; int fd; + // A very crude attempt... this supposes that STDIN not being a tty + // may never happen outside of "doveadm auth", and that STDIN will + // always be clean. + //if (!isatty(STDIN_FILENO)) + // i_fatal("stdin isn't a TTY"); if (!isatty(STDIN_FILENO)) - i_fatal("stdin isn't a TTY"); + { + pos = 0; + while (read(STDIN_FILENO, &ch, 1) > 0) { + if (pos >= buf_size-1) + break; + if (ch == '\n' || ch == '\r') + break; + buf[pos++] = ch; + } + buf[pos] = '\0'; + return; + } fputs(prompt, stderr); fflush(stderr); but this for sure must overlook a lot of things. What would be the best way to achieve a scriptable "doveadm auth", say through php's proc_open(), without possibly compromise passwords? TIA, Axel

[Dovecot] Plan: ACL changes
by Timo Sirainen 30 Nov '10

30 Nov '10

Global ACLs are intended to apply to a few mailboxes for all users. For example you could have a master user called "spam" that would have access to each user's "spam" mailbox, but nothing else. Global ACLs are kind of ugly. A mailbox's ACL is found from exactly the same name as what the mailbox's virtual name is. So for example if you have namespace { separator = / prefix = foo/ } And you have a mailbox called foo/bar, the global ACL is looked up from the <global dir>/foo/bar. The problem there of course is what if you want to set global ACLs for "foo". You can't have both directory and a file called "foo". So if this happens, Dovecot instead looks up the ACLs from <global dir>/foo/.DEFAULT file. The name for this file is slightly confusing, and also of course if there really is a mailbox called ".DEFAULT" it won't really work well. Global acl is currently configured by giving its path to acl setting, such as: plugin { acl = vfile:/etc/dovecot/global-acls } So plan #1: deprecate this usage. If global-acls is a directory, keep using the old method. But the new preferred method would be for it to be a file that contains all of the global ACLs. Typically there should be very few entries, so this should also be more efficient. Also this would allow setting default ACLs for namespaces by using wildcards. For example you could have: * masteruser +lrw spam spamuser +lr test/* testuser +lr etc. The * would match only within a single namespace, so if you had more than one, the * entry would match only the one having prefix="". The * entry would be especially helpful for master users who you intend to have access to user's all mailboxes. Currently there is no good way to implement this. Plan #2: Add support for per-user default namespace ACLs. In the mail root directory if "dovecot-default-acl" file exists, it's used as the default ACLs. I'm not entirely sure what should happen if it conflicts with the global ACLs. Probably they both should be simply merged, since both can only be created by an admin. Probably the per-user ACL should be allowed to override the global ACLs. Any thoughts? Since neither of these would break backwards compatibility, I could add them to v2.0.x.

[Dovecot] (vaguely) related to: "doveadm auth user" ...
by Clemens Schrimpe 30 Nov '10

30 Nov '10

While digging through the code I remember having seen something like an (yet undocumented) "update_query" for SQL (and I guess something similar for the LDAP faction as well)?! Can that be used to augment the "doveadm pw" function to actually /set/ the password for a given user instead of just "calculating" the hash, so that an operator can copy&waste it into the respective passdb? Just curious ... I guess it would be nice to have "doveadm" become as central point of administration (yeah, yeah - we would still need a "create user" and "delete user", etc. -- but we would at least be further on our way, wouldn't we? :-) Just 2¢ from Clemens

[Dovecot] SQL insert?
by Oliver Berse 29 Nov '10

29 Nov '10

Hi, I want to log some informations about a mail in a mysql database when the mail is saved to inbox (for a groupware). I use Dovecot 1.2.16 and the log message "msgid=<xxx>: saved mail to inbox" is generated in deliver.c. I find all the needed data in that file. But I'am not sure how to use the functions in sql-api.h or sql-api-private.h to send a simple SQL insert statement to the database. Can anyone give me a hint how to do this? best regards, Oliver

[Dovecot] Dovecot and loading OpenSSL libraries
by Paul Griffith 29 Nov '10

29 Nov '10

Hi, I am running into a interesting issue with Dovecot. I compiled Dovecot 2.0.7 with LD_RUN_PATH set to /xsys/lib and it was able to find and link against the correct OpenSSL libraries (/xsys/lib), the generated Makefile look OK. Here is a snippet of the SSL cflags and libs. SSL_CFLAGS = -I/xsys/include SSL_LIBS = -L/xsys/lib -lssl -lcrypto -ldl After I compil, install and run Dovecot I get the following error. ssl-params: Error: dovecot/ssl-params: error while loading shared libraries: libssl.so.0.9.8: cannot open shared object file: No such file or directory It seems that Dovecot can't find the SSL libraries, even if I set the LD_LIBRARY_PATH environment variable. I always assume that the Dynamic Loaded (dl) library would pickup LD_LIBRARY_PATH. If I add /xsys/lib to /etc/ld.so.conf and regenerate my /etc/ld.so.cache file, Dovecot works without any error messages. Any ideas why SSL_CFLAGS, SSL_LIBS and LD_LIBRARY_PATH aren't been honored ? 78 % /xsys/pkg/dovecot/bin/doveconf -n # 2.0.7: /xconf/dovecot/dovecot.conf # OS: Linux 2.6.9-89.0.29.EL.CSE.smp i686 CentOS release 4.6 (Final) ext3 auth_mechanisms = plain login auth_username_format = %Lu doveadm_socket_path = /var/run/dovecot/doveadm-server imap_client_workarounds = tb-extra-mailbox-sep mail_location = mbox:/local/home/%u:INBOX=/local/home/%u/inbox mail_plugin_dir = /xsys/pkg/dovecot/lib/dovecot passdb { driver = pam } pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_uidl_format = %08Xv%08Xu protocols = imap pop3 ssl_cert = </xconf/openssl/certs/imapd.pem ssl_key = </xconf/openssl/certs/imapd.pem userdb { driver = passwd } Thanks Paul

[Dovecot] maildir-dbox hybrid
by Roland Stuehmer 28 Nov '10

28 Nov '10

Hi! How can I convert old mailboxes in "maildir-dbox hybrid" to a current dbox? I have a Dovecot installation that was upgraded from 1.2.x to 2.0.x. Having used the old convert plugin during the 1.2-times I am now stuck with mailboxes which are partially converted (maildir-dbox hybrid state). On <http://wiki2.dovecot.org/Upgrading/2.0> it just says to contact the mailinglist. :) | If you have any Maildir files in your dbox, you need to convert them | somehow (contact Dovecot mailing list) Regards, Roland. P.S.: I am currently using version: 2.0.5 (b8803a1e2dc2)

[Dovecot] dovecot genesis v2.0.X
by Jim Pazarena 28 Nov '10

28 Nov '10

V2 of dovecot has had the following releases (to recap) 2.0.0 2010-08-16 2.0.1 2010-08-24 2.0.2 2010-09-08 2.0.3 2010-09-17 2.0.4 2010-09-26 2.0.5 2010-10-01 I am on FreeBSD, and the port committers want to wait till dovecot V2 "stabilizes" prior to adding it to the FreeBSD ports base. So, my question is, respectfully, is dovecot V2.0.5 stable enough for prime-time on a busy ISP mail server? I'll install it myself independent of the FreeBSD ports tree if so. Thanks,

[Dovecot] Mailbox Delete

Hi Timo.... I Modify the plugin autocreate, that create and subscribe a mailbox to user. My modification consist in do the inverse, if my user don't have permission to create and subscribe a folder, the plugin remove and unsubscribe. My function is called in the same place that create and subscribe is called, just seeing if my flag is "create or delete". My function i copy from doveadm + autocreate create mailbox. The delete is made, and works, but i got some errors before the delete.

My question is this: can I create a user "jsmith" to get all emails with the recipient address: dovecotdemo@domain? Because of using LDAP, I need to do a lookup to know that the user "jsmith" is getting emails for "dovecotdemo@domain", NOT "dovecotdemo" (there will be no such user). In postfix's master.cf, I can use LDA to deliver to DoveCot, which needs to know the user name where the message should be delivered to. But I would not know that at the time because I need to do a lookup in LDAP. Does the DoveCot delivery agent have any way to allow me return a different user name after LDAP lookup? I would not want to modify a couple of files to accomplish that, because I would have to do that for every email address created.

[Dovecot] (summarized) wishlist :-)
by Clemens Schrimpe 26 Nov '10

26 Nov '10

Hello All (and Timo in particular :-) -- While reading through some of the conversations on this list over the past two weeks or so, I always thought "how would <this> particular problem affect you and how would you address it in your environment?". This results in a few suggestions, or "thing to wish for", which I thought others may find useful, hence I'm posting this here. 1) the whole "post login scripting" is a mighty tool, yet it presently lacks a few more words in the documentation, i.e., the syntax of the corresponding config files isn't /entirely/ clear to me. Yes, I can replay the examples given, but I'm not fully sure, what happens when, etc. I'm perfectly willing, though, to contribute to that, by documenting findings in the Wiki2 (I'm just using 2.0.x, sorry). I'd appreciate a few more examples, so if anyone has a funny, working configuration, making good use of "post login scripting", I'd appreciate it, if you'd "show" them! :-) Anyway: A bit more "control" over PLS would be nice. For example, I'd like to have a script invoked every time a new "session" starts (new IMAP/POP3 connection from a unique ID), as many clients open multiple connections at once and usually I wouldn't want to see the second, third, nth connection - just the first. "Nice" would also a "post logout scripting" feature - again: Both for "all" connections, as well as just for the "last" one. Yes, this certainly requires a bit more discussion, I know - but I hope to trigger just that with this message! :-) 2) The "local x.x.x.x {" feature is very nice, yet it could use some "polishing", I guess. Inclusion of ports and wildcards for either addresses or ports, for instance. I'm imagining a syntax like this: local 1.2.3.4 { ... } like now to remain backward compatible local 1.2.3.4:* { ... } same result, just different new syntax -> don't care about port local 1.2.3.4:4711 { ... } add port restriction local *:4711 { ... } don't care for address, but match on port and -of course- (yes, I am really USING IPv6), the use of "[2001:xxxx:yyyy::zzzz]" instead of "1.2.3.4" in the examples show above. If one would like to become really funky, the optional "/xx" addition to specify a prefix-length would leave no more wishes open. (Well ... maybe the use of "names" derived from DNS instead of literal addresses, of course :-) [if this feature becomes clearer to me, I'd -again- be happy to help document it within the Wiki2] 3) The "iterate_query" in the SQL interface (I assume, there is something similar in the LDAP realm?) could be supplied with a few (optional, of course) "%x" variables, i.e., "%s" could deliver the "service" again, like with the other queries. This could tell the database engine, what the "show me all users" query is being used for ("quota", "expunge", ... basically all functions of doveadm, where you can supply a "-A" parameter). A "%{env:HOST}" could be used to tell the DB interface, which node of a multi-node installation is "asking". I.e., if you have your users distributed over multiple nodes, each one might want to perform "cleanups" only for their own users, saving a lot of bandwidth for unnecessary NFS traffic, etc. That's it - for now. Otherwise I'm pretty happy with dovecot, let me make that very clear here! :-) :-) :-) Clemens

[Dovecot] ioloop.c panic
by Brad Davidson 26 Nov '10

26 Nov '10

Timo, Just this morning I upgraded from 2.0.6 to 2.0.7 (hg changeset 66a523135836). A few hours later we had some power problems that caused the networking to drop out at one site. The directors on the surviving site all had a few imap-login processes crash with the following error: Nov 23 09:15:30 cc-director1 dovecot: imap-login: Panic: file ioloop.c: line 35 (io_add): assertion failed: (fd >= 0) Nov 23 09:15:31 cc-director1 dovecot: imap-login: Panic: file ioloop.c: line 35 (io_add): assertion failed: (fd >= 0) Nov 23 09:55:48 cc-director1 dovecot: imap-login: Panic: file ioloop.c: line 35 (io_add): assertion failed: (fd >= 0) Nov 23 09:55:51 cc-director2 dovecot: imap-login: Panic: file ioloop.c: line 35 (io_add): assertion failed: (fd >= 0) I don't have core dumps enabled, so I can't provide any more information than that.

[Dovecot] ldap passdb + mdbox
by Daniel L. Miller 26 Nov '10

26 Nov '10

I previously had a static userdb and an ldap passdb. Everything's been working fine, both 1.2 and 2.0 - but now I need to support the nightly mdbox purge operation. I added the iterate params to my ldap configuration, but (I'm guessing) that with a defined static userdb it won't work. How should I setup my ldap userdb? Do I use prefetch?

[Dovecot] proxy (director) and destination ports
by Oliver Eales 26 Nov '10

26 Nov '10

Hello, i am delivering Mail from postfix via LMTP to dovecot. I am using the director also for LMTP. As long as i connect to the dovecot LMTP TCP socket from postfix everything is working. postfix main.cf: virtual_transport= lmtp:localhost:30025 But when i try to switch to the local socket postfix main.cf: virtual_transport = lmtp:unix:private/dovecot-lmtp The dovecot proxy tries to connect to the backend server port 0 which is obviously not working. The proxy always seems to connect to the same port on the backend as it was accessed itself.

[Dovecot] Director and deliver
by Thomas Hummel 26 Nov '10

26 Nov '10

Hello Timo, Although I haven't tried neither director nor deliver, I'm planning to try both. I've been catching up with threads on this list talking about director but I'm not sure about how deliver would fit into a setup using director. Since deliver would touch indexes and dovecot-uidlist, wouldn't it need to be proxied as well through director ? Is that the case ? If not, how can we use deliver as LDA in a setup where n directors would proxy to m dovecot backends ? -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

[Dovecot] maildir maintenance?
by Brian Kroth 26 Nov '10

26 Nov '10

Hi, I'm running version 1.2.15 (so no doveadm) with around 6000 maildir users, some of which are very large. For completeness, the details of the setup are as follows: - The maildirs are stored via NFS. - The indexes are on a volume local to the dovecot server. - Only one IMAP server currently. - A separate sendmail/procmail server delivers via NFS. I recently wrote the attached script (could probably be improved) meant in theory to be run as a nightly cron job to do the follow: 1) Remove old messages marked as deleted. (I didn't really like the expunge/trash plugins the last time I looked at them.) 2) Rebuild the indexes to account of those changes. (So that the users aren't delayed by dovecot rebuilding them.) 3) Rebuild FTS indexes. (Again to avoid delay.) 4) Rebuild the maildirsize file. (It seems to become slightly inaccurate over time.) To the devs, I'm wondering if this seems sane? To other users of dovecot, I'm wondering what, if any sort of maintenance operations you tend to do in your setups? Thanks, Brian

[Dovecot] Quota by max file size
by Antonio Perez-Aranda 26 Nov '10

26 Nov '10

Is It possible have a quota for max file size? Per example, If the client try to save a very big mail as draft, p.e. 100M, and the limit of Exim configuration is 20M, the mail is really saved in Maildir at sent or Draft but it can't be sent. I think maybe is easy to create a plugin, get the saved stream size and then if it is over quota max file size, abort save and notice to use about the limit, but at first I want to know that really daesn't similar exists.

[Dovecot] iPhone leaves imap process active
by Jim 26 Nov '10

26 Nov '10

A quick search of the archives didn't reveal a fix, so I thought I'd ask the list. I was running Dovecot 2.0.2, and noticed a lot of CPU being used up. I discovered a number of IMAP processes burning a lot of cycles, when no connections should have been active. I traced this to the iPhone leaving the IMAP connection apparently active. I just upgraded to Dovecot 2.0.7, and I'm still seeing connections left active, but haven't seen the high CPU usage yet, but I've only been running 2.0.7 for about 30 minutes. I tried adding kill_idle to the IMAP config, but that doesn't seem to have helped. Turning off the iPhone does kill the connection, so I know that the iPhone is really keeping the connection alive, but if I can find a way to keep these connections down, I'd really rather have that ability. Here's my config: wrights-Mac-mini:/Users/transmit wright$ doveconf -n # 2.0.7: /usr/local/etc/dovecot/dovecot.conf # OS: Darwin 10.4.0 i386 hfs auth_mechanisms = plain login cram-md5 default_internal_user = _dovecot disable_plaintext_auth = no first_valid_gid = 27 first_valid_uid = 27 last_valid_gid = 27 last_valid_uid = 27 mail_gid = 27 mail_location = maildir:/var/mail/vhosts/%d/%n mail_privileged_group = postfix mail_uid = 27 namespace { inbox = yes location = prefix = type = private } passdb { args = /usr/local/etc/dovecot-mysql.conf driver = sql } protocols = imap pop3 service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } user = root } service imap-login { process_limit = 64 } service imap { idle_kill = 150 secs process_limit = 128 } service pop3-login { process_limit = 64 } service pop3 { process_limit = 128 } ssl = no userdb { args = /usr/local/etc/dovecot-mysql.conf driver = sql } protocol lda { postmaster_address = postmaster(a)example.com } wrights-Mac-mini:/Users/transmit wright$

Hello, i use dovecot 1.2.11 with auth by mysql. auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@üÜöÖäÄ for some reasons more special chars in username are needed. in fact the % char is meant.

[Dovecot] dovecot transport with postfix and recipient restrictions.
by Mauro 25 Nov '10

25 Nov '10

I'm using dovecot deliver with my postfix smtp. In postfix configuration I have: smtpd_recipient_restrictions = check_recipient_access hash:/etc/postfix/maps/recipient_checks and in recipient_checks I have: mail(a)example.com REJECT. It doesn't work. Perhaps the recipient restriction has to be put in dovecot side? How can I do this.

[Dovecot] Automatic expire on post-login

I need to clear two folder from Maildir at login. Exatly, delete all mails older than 30 days on Trash and 1 day on spam folder. I'm using dovecot 2.0 and I think about use a post-login script calling doveadm -u $user expunge but post-login scripts in dovecot 2.0 are very complex Is there possible to get the environment vars like on dovecot 1.2 ? I think this action must be done by expire plugin, but it isn't the work method if as I understand after read wiki2.dovecot.org about expire plugin, It run only with a cronjob.

Running "doveadm purge" with both -D and -v parms, and both -A and -u options, I don't see much in the way of output. doveadm -v purge -u username just returns with no output doveadm -v purge -A returns no output for most users - for my own mailbox it yields "20 / 21" -D returns the same, along with messages about skipping plugin modules. Is this normal? I'm thinking not - since after deleting messages in the client, emptying the trash, compacting from the client, and then performing a purge - I see no difference in mailbox files. -- Daniel

[Dovecot] two mailboxes - sieve?
by Egbert Jan van den Bussche 24 Nov '10

24 Nov '10

Hi helpful list! I have this user that has two different accounts om the mail server. One is a system account, the other is a virtual account (for what it is worth...). This user would like to have all his email to the virtual mail box (maildir format) automatically moved (or delivered) to the system mailbox (also maildir fornat). Both are on the same machine and use the same postfix/dovecot installation. Something tells me that I might need the sieve plugin for lda here since dovecot is the local delivery transport. I have no knowledge whatsoever about sieve or its scripting. What do I need to o apart from enabling the sieve plugin in dovecot.conf? Or is there another simple solution for this problem directly in Postfix or with fetchmail? A simple working example would be wonderful! TIA Egbert Jan (NL)

[Dovecot] gnus/dovecot open transactions panic
by Greg Troxel 24 Nov '10

24 Nov '10

I have been using dovecot with gnus for a long time. Recently, I started getting failures, and I think it's a dovecot problem triggered by gnus being more aggressive, but I'd like to hear opinions about whether I should pursue this as a gnus bug. The log shows: Oct 25 19:27:36 gdtserver dovecot: IMAP(gdt): Panic: Trying to close mailbox foo.bar with open transactions Oct 25 19:27:36 gdtserver dovecot: dovecot: child 26231 (imap) killed with signal 6 (core not dumped - set mail_drop_priv_before_exec=yes) and this seems to be triggered when dovecot is going GCC: to a local mailbox (not imap) when sending, but also semi-randomly. most of dovecot -n: (I'm sure that I'm not having auth problems and would rather not post that part): # 1.2.14: /usr/pkg/etc/dovecot.conf # OS: NetBSD 5.1_RC1 i386 protocols: imaps login_dir: /var/run/dovecot/login login_executable: /usr/pkg/libexec/dovecot/imap-login login_processes_count: 4 login_max_processes_count: 16 max_mail_processes: 32 first_valid_uid: 128 mail_location: maildir:~/IMAP I have 162 mailboxes polled by gnus on this dovecot instance. I get the panic on various mailboxes and I can't see a pattern. I do get Checking new news... nnimap-send-command: SIGPIPE raised on process *nnimap*; closed it From gnus. I then look at the listed one in the panic, and *imap-log* From gnus. This just may be an artifact of pipelining, but the panic-list mbox has 30 more after it that were sent, as in: 19:35:43 506 EXAMINE "mbox.named-in-panic" (QRESYNC (1208908407 1)) [30 more lines] I'm guessing that this is a dovecot problem. I realize I should update to 1.2.15 :-) but I didn't see anything in the 1.2.15 release notes that looks like a match.

[Dovecot] Doveoct crashes: UID
by Peer Heinlein 23 Nov '10

23 Nov '10

We're running Dovecot 2.0.2 and sometimes a user creates several imap- prozesses, all of them hanging with the UID-command, using 100% of the CPU resources: root@mail:~# ps ax | grep UID 8005 ? R 266:52 dovecot/imap [user(a)example.com 192.168.5.5 UID] 10342 ? R 250:33 dovecot/imap [user(a)example.com 192.168.5.5 UID] 10539 ? R 248:28 dovecot/imap [user(a)example.com 192.168.5.5 UID] 11150 ? R 245:03 dovecot/imap [user(a)example.com 192.168.5.5 UID] 11525 ? R 243:55 dovecot/imap [user(a)example.com 192.168.5.5 UID] This situation is triggered by two users only. Looks like their mailclient is sending a special command, that triggers the crash. Is it a bug or another problem? Is this a bug already fixed in Dovecot 2.0.3? - Fixed an infinite loop introduced by v2.0.2's message parser changes. Unfortunetaly I can't try an update at the moment. :-( Peer -- Heinlein Professional Linux Support GmbH Linux: Akademie - Support - Hosting http://www.heinlein-support.de Tel: 030 / 40 50 51 - 0 Fax: 030 / 40 50 51 - 19 Zwangsangaben lt. §35a GmbHG: HRB 93818 B / Amtsgericht Berlin-Charlottenburg, Geschäftsführer: Peer Heinlein -- Sitz: Berlin
