[Dovecot] Highly Performance and Availability
by Wayne Thursby 22 Feb '10

22 Feb '10

Hello everyone, I am currently running Dovecot as a high performance solution to a particular kind of problem. My userbase is small, but it murders email servers. The volume is moderate, but message retention requirements are stringent, to put it nicely. Many users receive a high volume of email traffic, but want to keep every message, and *search* them. This produces mail accounts up to 14+GiB. After seeing the failures of my predecessors, I transitioned to Postfix/Dovecot and haven't looked back. Things are running nicely with the below setup. Postfix and Dovecot running on the same virtual machine on a Dell 2950 with 1x Xeon E5440 on ESXi 4. Maildirs served up by 10x146GB 15k RPM SAS drives on RAID-10 via direct attached Dell MD-1000. We are transitioning other services to high availability, and I'm wondering exactly how to provide some kind of near-realtime failover for my Postfix/Dovecot machine. The MD-1000 provides nothing in the way of iSCSI, but it *does* have two SAS connections available, only one of which is in use. I have been looking at the Dell EqualLogic stuff and it seems to provide what we need. I can get most of the information I need from the rep, but I wonder if anyone has any experience with high performance requirements on these kinds of storage. I'd like to continue running my current hardware as the primary mail server, but provide some kind of failover using the SAN. The primary usage of the SAN will be to make our 2TB document store highly available. I'm wondering what kind of options I might have in the way of piggybacking some email failover on this kind of hardware without sacrificing the performance I'm currently enjoying. Is it possible to go with a virtual machine mounted on iSCSI acting as a backup mail server? How would I sync the two, NBD+MD? Any experience doing this with maildirs? I wonder about the performance. Can it be as simple as attaching my MD-1000's second controller to the SAN magic box via SAS and pressing the Easy button? Is it as expensive as running my primary mailserver mounted from the SAN via Fiber Channel? Will that get me under 30ms latency? I welcome any suggestions the group may have. -- Wayne Thursby System Administrator Physicians Group, LLC

[Dovecot] Best inode_ratio for maildir++ on ext4
by Rodolfo Gonzalez 22 Feb '10

22 Feb '10

Hi, This might be a silly question: which would be the best inode ratio for a 5 Tb filesystem dedicated to Maildir++ storage? I use ubuntu server, which has a preconfigured setting for mkfs.ext4 called "news" with inode_ratio = 4096, and after formating the fs with that setting and then with the defautl setting I see this difference of space (wasted space, but more inodes): 4328633696 free 1K-blocks with mkfs's "-T news" switch = 1219493877 free inodes 4557288800 free 1K-blocks with default mkfs settings = 304873461 free inodes I'll be storing e-mail messages for around 20,000 accounts on that partition (average 512 Mb per account). Would you consider worth the waste of about 200 Gb of the filesystem space in exchange of more inodes? Thanks. Rodolfo.

[Dovecot] enabling IMAP SORT and THREAD extensions
by Colin Brace 21 Feb '10

21 Feb '10

Hi all, The home page of the Dovecot website indicates: "Supports multiple commonly used IMAP extensions, including SORT, THREAD and IDLE." However, I cannot find instructions in the Wiki for how to enable these extensions. Can someone tell me how to do this? I will add this info to the Wiki myself if need be.

[Dovecot] Dovecot blog
by Timo Sirainen 20 Feb '10

20 Feb '10

http://blog.dovecot.org/ I was thinking that I could blog about: - ideas for new Dovecot feature designs - when I actually manage to implement some new great feature - maybe some stuff about IMAP/email in general - and maybe whenever I happen to be moving to a different country I wasn't really planning on announcing new releases there. Dovecot feature designs are also sent to Dovecot mailing list, as before. But there have been other things I've thought about mentioning somewhere, but Dovecot ML didn't really seem like the right place. I doubt I'll update the blog very often. But that probably makes it even more useful, since casual readers find the useful stuff quickly. :)

[Dovecot] Virtual POP3 Inbox question
by Josephus 20 Feb '10

20 Feb '10

Hi, I'm having trouble implementing the virtual pop3 inbox solution in Dovecot 1.2.x. As the following wiki page describes (http://wiki.dovecot.org/Plugins/Virtual) one should only set the inbox=yes flag for the virtual namespace which then flattens all mailboxes in the realmails/ prefix. In the above example when I set the inbox=yes flag for the virtual namespace, the inbox in the realmails/ prefix gets left out for obvious reasons. How did the original author intend this to work? Regards, Jos

[Dovecot] Dovecot design-question
by Werner 20 Feb '10

20 Feb '10

Hi everybody, we're currently in the process of drafting our new mailserver-setup. Instead of a single-server-setup we'd like to have two equal servers behind a loadbalancer like LVS and shared mailhomes on NFS. We'd like to use dovecot for POP/IMAP, dovecot-deliver as LDA. - It's probably the best idea to direct SMTP and POP/IMAP always to the same server behind the loadbalancer (because dovecot-deliver is used which updates indexes?) - If we think of a "active/passive" setup: dovecot index-files locally or on the nfs-share? - Is it possible to activate loadbalancing for SMTP in this environment if dovecot index-files are held locally on each machine (POP/IMAP is directed only to one of the two servers?) Any comments welcome :-) Werner

[Dovecot] exporting client socket to postfix
by zhong ming wu 20 Feb '10

20 Feb '10

Dear List, I have a few questions regarding dovecot sasl authentication that are somewhat related to each other. I have a working dovecot config with ---------- ssl_verify_client_cert = yes .. . ssl_require_client_cert = yes ssl_username_from_cert = yes --------------- (With this set up I need not set a correct user name in my mail client so long as I have it correctly in cert.) It turns out that I cannot export client socket to postfix to do smtp authentication unless I comment out ssl_require_client_cert=yes Does it mean that postfix is not passing to dovecot any information about certificate? Is passing certificate information not part of sasl framework? If so I won't be able to use it with a different sasl implementation. Also if I comment out ssl_require_client_cert=yes, then I can no longer use username from cert to log in to retrieve my pop mail. I prefer to get username this way otherwise my thunderbird mailbox reads user@domain.org@domain.org; I could have more than one domain in my dovecot servers. Thanks mr.wu

[Dovecot] passing parameters to deliver
by kjonca＠wp.pl 20 Feb '10

20 Feb '10

Is any posibility to pass parameters/environment variables to deliver with sieve plugin? I have some procmail rules to decide where mail should go, which can't be migrated to sieve (uses external programs). So far I write it to maildirs, but I wonder to migrate to mdbox, and procmail can't handle it. Any ideas?

[Dovecot] Feature request? Make deliver quota inclusive!
by Joachim Boltz 19 Feb '10

19 Feb '10

hi all, I'd like to make deliver put mail into a nearly full mailbox even when they become overquota as a result. The same problem came up a few weeks ago: http://dovecot.org/list/dovecot/2010-January/045695.html Since no solution was offered may I suggest this topic as an additional feature for future releases? ;-) This is a important for me because sometimes users are lazy. They think "oh, still 10% left, no reason to delete mail" while in the meantime large messages are already bounced, while some small ones arrive in the users inbox. cheers, achim

[Dovecot] Client behaviour with sieve
by Koenraad Lelong 19 Feb '10

19 Feb '10

Hi, I have a working dovecot imap-server, with sieve. I find it odd that my mail-clients (Thunderbird 2 and 3) don't report anything that's new in the folders. What I mean is this : Postfix get's a mail and hands it over to dovecot's LDA and sieve moves it to a folder. When I log in with Thunderbird, I see new messages in my Inbox. But that message that was moved to a folder is "invisible" until I click on the folder. Then Thunderbird sees there are new messages in that folder and reports the number of new messages and makes the foldername bold. Is this the expected behaviour ? Or did I configure something wrong ? Thanks for any clarification. Regards, Koenraad Lelong.

[Dovecot] wish now I'd not upgraded...
by Stan Hoeppner 19 Feb '10

19 Feb '10

Upgraded from Debian Dovecot 1.0.15 to Debian Dovecot 1.2.10-1~bpo50+1. I use Postfix local delivery to and Dovecot mbox. As per upgrade directions, I stopped dovecot processes and deleted all dovecot.index.cache files in /home/%user/mail/.imap. Performed upgrade to 1.2.10-1~bpo50+1. Modified new dovecot.conf for my environment. Started dovecot. Problem: Instantly noticed in TB 3.0.1 Win32 that all emails in all folders were marked as unread. Stopped TB, stopped dovecot, deleted *all* files in /home/%user/mail/imap/ so indexes and caches could be rebuilt from scratch. Started dovecot, started TB. Same problem. Then I got ugly, stopped TB and dovecot, deleted all ~.imap/ files *and* deleted *all* TB cache and index files with a time stamp of today. Restarted dovecot, restarted TB. Same damn problem. I sit hit right clicking folder after folder and selecting "mark as read", only to see all the emails in the folder go "read" and then within seconds go back to marked as unread (bold). Opening messages one at a time and moving to the next doesn't even keep them marked as read. WTF is going on? Why won't they stay marked as read? I've got over 25,000 emails in these folders and I get a few hundred list mails a day. I really need to get this read/unread business straightened out. What the heck am I missing? Is this a bug in the Debian backport? Good thing I have no hair or I'd have pulled half of it out by now... -- Stan

[Dovecot] quota problem
by Andre Hübner 19 Feb '10

19 Feb '10

dovecot 1.0.15 Hello, i try to set quota settings for my users. currentyl i use a mysql table for auth process and now i want to add quotasettings for each individual user. at the moment i have the problem that only global quota is effective and no userquota which is stored in usertable. This is my mysql-usertable: login varchar(255) password varchar(64) home varchar(128) uid int(11) gid int(11) quota_kb varchar(10) active char(1) In my main-dovecot.conf i have quota/imap_quota activated for pop/imap and protocol lda This is the auth-section which contains passdb/userdb auth default { mechanisms = plain login passdb sql { args = /etc/dovecot-sql.conf } userdb sql { args = /etc/dovecot-sql.conf } user = root socket listen { client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } socket listen { client { path = /var/run/dovecot/auth-master mode = 0755 user = nobody } } } SQL-queries in /etc/dovecot-sql.conf (connection itselfs is ok, auth per mysql is working already) password_query = SELECT login as user, password, home as userdb_home, uid as userdb_uid, gid as userdb_gid FROM mail_users WHERE login = '%u' AND active='Y' user_query = SELECT login as user, home, uid, gid, concat('dirsize:storage=', quota_kb) AS quota FROM mail_users WHERE login = '%u' I think there is something missing in my conf but have no idea what it could be. I need a little hint please. Thanks, Andre

[Dovecot] auth processes
by Stan Hoeppner 19 Feb '10

19 Feb '10

With 1.0.15 my configuration I a single dovecot-auth process, which is what I want now. Since upgrading to 1.2.10 I have two such processes: root 16992 16990 0 Feb15 ? 00:00:00 dovecot-auth root 16997 16990 0 Feb15 ? 00:00:00 dovecot-auth -w I can't seem to tweak dovecot.conf to get this down to one auth process again. I've tried setting each of these below to 0, which resulted in either none, or one auth process. In the case of the one auth process, T-Bird wasn't working correctly, although it presented no pop up or other errors. When I'd click an IMAP folder it would just show whitespace and never pull up the emails. auth_worker_max_count = # Number of authentication processes to create count = This is an extremely low volume host, and I'm an efficiency freak. I don't like having "unnecessary" processes running if it is at all possible to avoid it. Given my IMAP user load, I know for a fact that I should only need one auth process, and for that matter, given my load, running all the dovecot processes from inetd is even a valid option, although I've not yet attempted that. Any ideas? Thanks. -- Stan

[Dovecot] dovecot and firstname.initial.lastname mbox format archive
by Wilko Bulte 19 Feb '10

19 Feb '10

hi Today I have been in a puzzling fight with 2 dovecot versions that I would like to ask some comments on. The situation is this: - I have a considerable mail archive in mbox format (yes, I know, but that is what I have..). - My mail reader is mutt 1.5.20 by the way. - Some of these mbox files have names like firstname.initial.lastname Note the . seperating the parts of the email-ers name. - On my old system I have dovecot v 1.1.7 which has always worked flawless - On my new system I have dovecot v 1.2.8 which refuses to handle these dot-seperated files. I get the somewhat familiar "Mailbox doesn't allow inferior mailboxes". On a not-previously-existing mbox dovecot 1.2.8 produces the directory hierarchy thing: firstname -> initial -> lastname - I am using the same dovecot.conf on v.1.1.7 and v.1.2.8 Can anyone tell me if v1.2.8 no longer is able to do what v1.1.7 did? And what I dearly would like to get working :-( And if it can, what should I put in dovecot.conf to make that happen? thanks, Wilko -- wilko(a)FreeBSD.org

[Dovecot] 2nd REPOST: mbox vs maildir
by Ashley M. Kirchner 18 Feb '10

18 Feb '10

I'm going to assume this is just not possible, or that no one has an answer, which would lead me back to uw-imap since it does work as-is. So I'll post it again, hoping that there is a solution for this setup and that folks have just been too busy to help think about it and/or help come up with a possible solution. ----- Ignoring my previous message just for a second, I realized that my config wasn't correct. First the layout: ~mail/ ~mail/Drafts ~mail/Ashley-Feb09 ~mail/Others-Feb09 ~mail-Archives/ ~mail-Archives/2009/ ~mail-Archives/2009/Ashley/ ~mail-Archives/2009/Ashley/Ashley-Dec09 ~mail-Archives/2009/Ashley/Ashley-Nov09 ~mail-Archives/2009/Ashley/Ashley-Oct09 So I (now) have this for namespaces: namespace private { separator = / prefix = "mail/" location = mbox:~/mail:INBOX=/var/mail/%u inbox = yes hidden = no list = yes # for v1.1+ } namespace private { separator = / prefix = "mail-Archives/" location = maildir:~/mail-Archives:LAYOUT=fs inbox = no hidden = no list = yes subscriptions = yes } But when I'm in Thunderbird and I try to subscribe to anything that falls inside of ~/mail-Archives/ it won't work. I can browser all the way down to the folder, but I can't see anything within that folder. For example, consider the full path to the following 'Ashley-Dec09' mailbox: ~mail-Archives/2009/Ashley/Ashley-Dec09 In Thunderbird, when I hit 'Subscribe' I can browse down to '2009' and I can see 'Ashley', but I can't drill down into it and subscribe to 'Ashley-Jan09'. What am I missing here?

[Dovecot] LDAP as password database - some problems / suggestions
by Stefan Palme 18 Feb '10

18 Feb '10

Hi all, Using dovecot-1.2.6, I use dovecot with an LDAP backend for user authentication. In general this works ok, but I have some issues with this... In LDAP, I have users like this: dn:cn=user1,ou=users,dc=kapott,dc=org dn:cn=user2,ou=users,dc=kapott,dc=org etc. When authenticating users, I explicitely want to use the AUTH_BIND feature (and NOT lookup passwords). My problem: not ALL users from the LDAP system should be allowed to use the IMAP server. Currently, I have defined an auth_bind_userdn of "cn=%u,ou=users,dc=kapott,dc=org" in dovecot-ldap.conf, but with this, user1 AND user2 could login (but I don't want user2 to be able to use dovecot). Because the LDAP system is used in a larger environment, it is NOT possible to re-arrange the users like this: cn=user1,ou=dovecot,ou=users,dc=kapott,dc=org cn=user2,ou=not_dovecot,ou=users,dc=kapott,dc=org So my question: are there any plans to support group-based LDAP authentication? For several other application, I have something like this: dn:cn=dovecot,ou=groups,dc=kapott,dc=org objectclass:groupOfNames member:cn=user1,ou=users,dc=kapott,dc=org So I can define groups of user accounts - one group per application. A nice solution for this in dovecot would be, if I could "mix" password lookup and authentication bind: First, a search query should be used to find a valid DN to bind as. In my case, the search query could look like this: base="ou=groups,dc=kapott.org" filter="(&(cn=dovecot)(member=cn=%u,ou=users,dc=kapott,dc=org))" result_attribute="member" After finding a DN this way (via attribute "member"), I want to use auth_bind to use this DN for password verification... Any hints how to solve this? Any plans to support this in the future? Thanks and regards -stefan-

Is there a correct way to tell the client we don't want, and don't support Keywords via a configuration option? If there's no configuration option, would I override "allow_new_keywords" to just return FALSE? Thanks, Tony

[Dovecot] Courier->Dovecot Migration Issue
by Tony Rutherford 18 Feb '10

18 Feb '10

For testing purposes, on a small set of users, we've run the courier-dovecot-migrate.pl script. We are converting from Courier 0.43 to Dovecot 1.2.9. For the most part, things seem to be ok. However, an iPhone IMAP client user is reporting a problem where some of her messages don't show up. Even stranger is the fact that these same messages do appear when using Outlook 2k7 for instance. The common denominator for when the messages are missing seems to be whether or not the message appeared in both the Courier IMAP and Courier POP3 uid files. The missing messages appear in the CourierIMAP file, but NOT the Courier POP file. Here is a snippet from the resulting Dovecot-uidlist file: 3 V1141844265 N12392 9338 P00cf2eb6_fadc_4992_ad3a_57cc83a16eab W5146 :00cf2eb6_fadc_4992_ad3a_57cc83a16eab:2,S 9788 P0b18a2d6_97dd_4712_a09c_23c7a3d59467 W4055 :0b18a2d6_97dd_4712_a09c_23c7a3d59467:2,S 9942 P0b3cfd0b_1fc7_47b3_805f_b369a3bb6c65 W4359 :0b3cfd0b_1fc7_47b3_805f_b369a3bb6c65:2,S 10100 Pe178f1ed_d648_47e8_807a_3e2d655d7f84 W12028 :e178f1ed_d648_47e8_807a_3e2d655d7f84:2,S 10101 Pe3f28a53_a4d4_4f3d_babe_5df72bc35b47 W13974 :e3f28a53_a4d4_4f3d_babe_5df72bc35b47:2,S 10102 Pf3c3024b_2850_43ef_a397_d5cae5c8f537 W7177 :f3c3024b_2850_43ef_a397_d5cae5c8f537:2,S 10104 P6e808a68_0a7b_4528_aa67_4cc16361c56b W10817 :6e808a68_0a7b_4528_aa67_4cc16361c56b:2,S 10105 P65c8218d_7b2a_43b7_82a4_2743025bd954 W3579 :65c8218d_7b2a_43b7_82a4_2743025bd954:2,S 10106 P963cc43e_0355_481e_99d5_5468708bc28f W6410 :963cc43e_0355_481e_99d5_5468708bc28f:2,S 10107 P1405aefc_b98b_4a35_a7dd_a69199f724d0 W4703 :1405aefc_b98b_4a35_a7dd_a69199f724d0:2,S 10108 P67908fad_ec0a_4786_b0f1_c7cfaa23d09a W127288 :67908fad_ec0a_4786_b0f1_c7cfaa23d09a:2,S 10109 :9176f3b2_1927_4657_baa8_bfe4c39e89d4:2,S 10110 :79047185_aef7_48ec_aff2_6b71bd566acd:2,S 10111 :efe275a0_a7a8_4f47_b638_45a18bc0b108:2,S The last three entries exist in the Courier IMAP file, but NOT the Courier POP file. The resulting dovecot-uidlist format is different, but to be honest, I haven't been able to find the exact specification for the format of the dovecot-uidlist file (if it exists). What is really strange to me is: If there was a problem with the migration script and resulting dovecot-uidlist file, why would these messages show up fine in some client (ex. Outlook) and not others (ex. iPhone). Regards, Tony

[Dovecot] Virtual mailboxes show up twice
by Matthijs Kooijman 18 Feb '10

18 Feb '10

Hi all, I've been struggling a bit getting Hastymail webmail to work with my virtual mailboxes. After a while, I discovered that my virtual mailboxes are listed twice: Once with \NoSelect and once without. See the following (partial) LIST reponse: * LIST (\Noselect \HasChildren) "/" "virtual" * LIST (\Noselect \HasNoChildren) "/" "virtual/foo" ... * LIST (\HasNoChildren) "/" "virtual/foo" This makes somewhat sense, since my "virtual" namespace is a subdir of my default namespace: mail_location = Maildir:~/Mail:LAYOUT=fs # Default namespace, uses mail_location above namespace private { prefix = separator = / inbox = yes } # Virtual mailboxes namespace private { prefix = virtual/ separator = / # Store virtual mailbox in a "virtual" subdirectory. We use the fs layout, # so nesting of mailboxes is done using normal filesystem nesting. location = virtual:~/Mail/virtual:LAYOUT=fs } Now, should dovecot handle this configuration transparently by hiding the virtual directory from the default namespace, or is this configuration just not supported and should the virtual directory be outside of ~/Mail? The current wiki documentation on the virtual plugin currently does suggest this configuration, its examples point to ~/Maildir/virtual. Gr. Matthijs

From dovecot 1.2.10 sources i have: src/plugins/quota/quota.c #define DEFAULT_QUOTA_EXCEEDED_MSG \ "Quota exceeded (mailbox for user is full)" struct quota_settings *quota_settings_init(void) { [ .... ] quota_set->quota_exceeded_msg = getenv("QUOTA_EXCEEDED_MESSAGE"); if (quota_set->quota_exceeded_msg == NULL) quota_set->quota_exceeded_msg = DEFAULT_QUOTA_EXCEEDED_MSG; [ .... ] but i havent found, in all the sources, where the QUOTA_EXCEEDED_MESSAGE is feeded by something from dovecot.conf or anywhere else. question is: isnt it possible to configure the quota exceeded message from dovecot.conf ??

[Dovecot] Problem in sharing mailboxes across users
by Rampage 18 Feb '10

18 Feb '10

Hello everyone, I'm trying to configure dovecot to allow users to share their imap folders. I've followed the wiki and i'm near to accomplish my tasks, when i set ACL properly on folders using imap commands the other user can see the folder as shared, but i can't subscribe to it or even access its content using any email client (like thunderbird) couse it looks like the path to the shared folder is not complete. i mean when i go to "manage subscriptions" i can see the shared folder from the other users as "shared/user@domain/sharedfoldername" but since only "sharedfoldername" is present i cant subscribe to it. am i missing somethimg? like do i need to setup a particular directory tree on the filesystem? thnx in advice for your help. Best regards. Francesco.

[Dovecot] Problem with allow_nets passdb parameter and Postfix
by Неворотин Вадим 18 Feb '10

18 Feb '10

I use Dovecot for SASL authentication from Postfix. In Postfix main.cf I have: smtpd_sasl_type = dovecot It works good, but now I need to allow users to connect by IMAP only from given IP adresses. I've added extra field allow_nets to passdb in Dovecot, and IMAP authentication works fine. But now I can't connect to my SMTP server because when smtpd ask dovecot about user authentification, dovecot always denied it. Even if I try to connect to SMTP from correct IP, listed in allow_nets for user. In dovecot log I have messages about incorrect ip like this: dovecot: 2010-02-15 13:28:51 Info: auth(default): passwd-file(malamut): lookup: user=malamut file=/etc/dovecot/temp.users dovecot: 2010-02-15 13:28:51 Info: auth(default): passdb(malamut): allow_nets check failed: Remote IP not known dovecot: 2010-02-15 13:28:53 Info: auth(default): client out: FAIL 7 user=malamut Problem is clear: smtpd don't send client IP to dovecot authentication socket. But I need to limit the ability of connection to users only from specific IP. Both for SMTP and IMAP. How can I do that? I use dovecot 1.0.15 and Postfix 2.5.5 on Debian Lenny.

[Dovecot] quick question
by David Halik 18 Feb '10

18 Feb '10

Timo (and anyone else who feels like chiming in), I was just wondering if you'd be able to tell me if the amount of corruption I see on a daily basis is what you consider "average" for our current setup and traffic. Now that we are no longer experiencing any core dumps with the latest patches since our migration from courier two months ago, I'd like to know what is expected as operational norms. Prior to this we had never used Dovecot, so I have nothing to go on. Our physical setup is 10 Centos 5.4 x86_64 IMAP/POP servers, all with the same NFS backend where the index, control, and Maildir's for the users reside. Accessing this are direct connections from clients, plus multiple squirrelmail webservers, and pine users, all at the same time with layer4 switch connection load balancing. Each server has an average of about 400 connections, for a total of around concurrent 4000 during a normal business day. This is out of a possible user population of about 15,000. All our dovecot servers syslog to one machine, and on average I see about 50-75 instances of file corruption per day. I'm not counting each line, since some instances of corruption generate a log message for each uid that's wrong. This is just me counting "user A was corrupted once at 10:00, user B was corrupted at 10:25" for example. Examples of the corruption are as follows: ########### Corrupted transaction log file ..../dovecot/.INBOX/dovecot.index.log seq 28: Invalid transaction log size (32692 vs 32800): ...../dovecot/.INBOX/dovecot.index.log (sync_offset=32692) Corrupted index cache file ...../dovecot/.Sent Messages/dovecot.index.cache: Corrupted physical size for uid=624: 0 != 53490263 Corrupted transaction log file ..../dovecot/.INBOX/dovecot.index.log seq 66: Unexpected garbage at EOF (sync_offset=21608) Corrupted transaction log file ...../dovecot/.Trash.RFA/dovecot.index.log seq 2: indexid changed 1264098644 -> 1264098664 (sync_offset=0) Corrupted index cache file ...../dovecot/.INBOX/dovecot.index.cache: invalid record size Corrupted index cache file ...../dovecot/.INBOX/dovecot.index.cache: field index too large (33 >= 19) Corrupted transaction log file ..../dovecot/.INBOX/dovecot.index.log seq 40: record size too small (type=0x0, offset=5788, size=0) (sync_offset=5812) ########## These are most of the unique messages I could find, although the majority are the same as the first two I posted. So, my question, is this normal for a setup such as ours? I've been arguing with my boss over this since the switch. My opinion is that with a setup such as ours where a user can be logged in using Thunderbird, Squirrelmail, and their Blackberry all concurrently at the same time, there will always be the occasional index/log corruption. Unfortunately, he is of the opinion that there should rarely be any and there is a design flaw in how Dovecot is designed to work with multiple services with an NFS backend. What has been your experience so far?

[Dovecot] dovecot-sieve vacation vs qmail-ldap

How to fix it ? I was thinking about deliver extracting target address from Delivered-To: header added by qmail's preline, or use DTLINE env variable, whitch qmail populates with Delivered-To header.

[Dovecot] using signed certificates for TLS/SSL
by Leonardo Rodrigues 18 Feb '10

18 Feb '10

Hi, I have, in one customer, a web server running on a Verisign-signed certificate SSL certificate. Everything works fine, IE and Firefox connects on https without asking anything, which usually happens on self-signed certificates. I'm trying to use that certificate on dovecot, but clients (Thunderbird basically) keeps saying the certificate is not valid. yes i'm using, when configuring Thunderbird, the same CN that was signed by Verisign for the web usage i've enabled verbose_ssl and got when thunderbird tries to connect: Feb 18 12:32:02 correio dovecot: imap-login: Disconnected (no auth attempts): rip=201.86.xxx.xxx, lip=192.168.1.2, TLS handshaking: SSL_accept() failed: error:14094418:SSL routines:SSL3_READ_BYTES:tlsv1 alert unknown ca unknown CA ??? is that Thunderbird that is not recognizing the Verisign-signed certificate ? Do i need to, somehow, install some Verisign CA certificate in dovecot.conf ? when using a self-signed certificate, i also get an SSL_accept failed, but with different message: Feb 18 12:41:45 correio dovecot: imap-login: Disconnected (no auth attempts): rip=201.86.191.114, lip=192.168.1.2, TLS handshaking: SSL_accept() failed: error:14094412:SSL routines:SSL3_READ_BYTES:sslv3 alert bad certificate despite the fact my certificates were generated for use with Apache, i can 'print' them, both of them, with the same commands i use to print dovecot generated certificates, with mkcert.sh.

[Dovecot] revision control on maildir possible?
by Markus Beyer 18 Feb '10

18 Feb '10

Hi, I was wondering if it is possible to put a dovecot managed maildir under a vcs like system, for example git or bzr. I'd like to have a seamless history of all mail going in and out of my mailboxes, so a vcs like system seams a good choice for me. I'm not quite sure however if that would cause any problems to dovecot and what the best way of handling commits would be. If anyone on the list got any pointers regarding this, it would be much apprechiated. Best regards, Markus -- Sicherer, schneller und einfacher.

[Dovecot] Special user
by Daniel L. Miller 17 Feb '10

17 Feb '10

Not sure what to call this - I'm actually working out the details as I type this. I want to have a valid username/password for an account for sending purposes - but when receiving this is an alias that broadcasts to several users. Example: accountspayable(a)mydomain.com - is an alias for jane(a)mydomain.com, june(a)mydomain.com, and john(a)mydomain.com. However - any mails sent (from a particular client software) should all only show "accountspayable" as the sender. How would I implement this? I'm asking here because Dovecot serves as the authentication mechanism for my SMTP server (Postfix) via LDAP lookups. -- Daniel

[Dovecot] salted passwords
by Leonardo Rodrigues 17 Feb '10

17 Feb '10

The idea of salted hash algorithms is to generate a different hash even if the same text is entered. That can be easily seen with dovecotpw: using NON-salted SHA256, same hash is generated for a given password [root@correio ~]# dovecotpw -s SHA256 -p 123 {SHA256}pmWkWSBCL51Bfkhn79xPuKBKHz//H6B+mY6G9/eieuM= [root@correio ~]# dovecotpw -s SHA256 -p 123 {SHA256}pmWkWSBCL51Bfkhn79xPuKBKHz//H6B+mY6G9/eieuM= [root@correio ~]# dovecotpw -s SHA256 -p 123 {SHA256}pmWkWSBCL51Bfkhn79xPuKBKHz//H6B+mY6G9/eieuM= [root@correio ~]# using SALTED SHA256, a different hash is generated for the same given password [root@correio ~]# dovecotpw -s SSHA256 -p 123 {SSHA256}FpJZqafpEVKp2heepp9Z7+OeHaX+DBVpLzd6GKg3BW1XqDS0 [root@correio ~]# dovecotpw -s SSHA256 -p 123 {SSHA256}6lWmvtO3SKG5RMET5n89WMIp0xeCg3U14xH1xnAXbvkr8Yjk [root@correio ~]# dovecotpw -s SSHA256 -p 123 {SSHA256}7fXVjC7Iiu0Ko9SgyBpbDvbwMSkoxMILRjDUE0nNpCHBFaIa [root@correio ~]# This ideia is OK to me ... but i'm having a hard time trying to figure out how my dovecot-sql.conf would be in the case i store salted SHA256 passwords on the database. The idea is to use a RANDOM salt, not a fixed one, just like dovecotpw does. would it be as simple as changing the 'password', which today is plaintext, by something like concat('{SHA256}',password) ??? dont i have to give the salt, somehow ?? Or should i store the salt used in the password, for example first or last N characters .... is there anyone using dovecot with MySQL and SSHA256 passwords that can share me the dovecot-sql.conf file ? -- Atenciosamente / Sincerily, Leonardo Rodrigues Solutti Tecnologia http://www.solutti.com.br Minha armadilha de SPAM, NÃO mandem email gertrudes(a)solutti.com.br My SPAMTRAP, do not email it

Your results are even more impressive if that's the case. Sorry if it's less impressive, but I've certainly configured the VM for 4 cores. The cores are shared equally between all VMs, I've done no prioritization because I've not had any performance issues related to resource contention. Having 10x15k RPM spindles to seek across, and 512MB of cache on the controller, means I can give Postfix/Amavis/Dovecot 3GB of RAM to use, and 1GB of it is always used for cache, without ever dipping into swap. I get occasional spikes to 30ms of disk latency, but it stays below 5ms for most of the workday. > Also, are you seeing the classic system clock drift of ESX guests, > and if so, is it causing problems with smtp and imap? Not at all, that's what the VMware tools are for. The ESXi host is configured to use our NTP server inside the VPN, and the VMware tools package synchronizes the guest clock with the host. I ran into this on our webmail client as well, then I discovered how easy it really is to install the VMware tools on Ubuntu, so it's no longer a problem. Don't want to stray off topic, so I'll start a new thread, but I'm now attempting to bring High Availability to the mix, and could use some suggestions. -- Wayne Thursby System Administrator Physicians Group, LLC

[Dovecot] sieve addflag has stopped working
by Andrew Schulman 16 Feb '10

16 Feb '10

Dovecot 1.2.10 in Debian, using Dovecot sieve. I have a sieve script, generated by Ingo, that's supposed to mark spam messages as "Seen" and file them into the Junk folder. In part it reads: require ["regex", "body", "imapflags", "fileinto"]; if exists "X-Spam-Flag" { addflag "\\Seen"; fileinto "Junk"; removeflag "\\Seen"; stop; } This has been working correctly for a long time, but since about 2 weeks ago now, the "Seen" flag isn't being set, although the messages are still being filed into the Junk folder. In two different mail clients, new messages in the Junk folder show up as being unread. Looking at the mail files that hold those messages, the file names don't have an "S" flag appended, while older messages all have the "S" and show up as already seen in the mail clients. I don't believe that I've updated dovecot recently, so I'm not sure why the behavior has changed. Note that I do have plugin { sieve_extensions = +imapflags } in dovecot.conf. I know that imapflags is deprecated, but it is still supposed to be supported. Unfortunately ingo1 doesn't support imap4flags yet (http://bugs.horde.org/ticket/8784) I'm trying to find log information that might indicate an error, but I'm not finding much. /var/log/exim4/mainlog just says: 2010-02-15 14:22:14 1Nh6WK-000200-8z <xxx(a)xxx.xxx>: deliver_pipe transport output: deliver(andrex): Info: sieve: msgid=<ad58db2a42700ec0e5c924c8882d48c2(a)yourmailnews.net>: stored mail into mailbox 'Junk' The wiki says that there should be a log file ~/.dovecot.sieve.log, but there isn't one, which I guess means there are no error messages. Output of dovecot -a is below. Any ideas why the Seen flag isn't being set any more?

[Dovecot] Dovecot+Postfix+Maildir with ActiveDirectory userbase

> Luigi Rosa <lists(a)luigirosa.com> uttered: > Hi, > has anyone implemented a mail server with maildir, Postfix and Dovecot > using > Active Directory ad userbase and password authentication? > > Do I need Samba to authenticate users? > > Can I use credential caching just like mysql? > > > Ciao, > luigi > > -- > / > +--[Luigi Rosa]-- > \ Hi Luigi, I am running a Postfix/Dovecot setup that is authenticating against a Windows 2000 domain. It is possible to authenticate several different ways, including Kerberos/Winbind and NTLM via Samba. I used the following article as a guide. It is for FreeBSD, but the configuration instructions apply equally to any Postfix/Dovecot setup. I am running mine on Ubuntu 8.10. http://blog.al-shami.net/index.php/freebsd-postfix-dovecot-and-active-direc… The above article covers most of the setup, however I have changed a few things for my purposes. In short, I am using LDAP to communicate with the Active Directory server. I am looking up email addresses and aliases from AD in Postfix and using Dovecot as LDA. Postfix uses Dovecot's SASL for authentication, and Dovecot in turn authenticates against AD. My Setup: Postfix and Dovecot running on the same virtual machine on a Dell 2950 with 1x Xeon E5440 on ESXi 4. Maildirs served up by 10x146GB SCSI drives on RAID-10 via direct attached Dell MD-1000. Serving 600+ users, mailbox sizes up to 14GiB with constant heavy searching (no fts yet) and filtering (sieve and IMAP clients). 80,000 messages delivered per week, 95,000 messages rejected, 17,000 spam. 15 minute Load average stays under .50 all day with 4 CPU cores. IMAP clients include Outlook 2007, Thunderbird 2 and 3, in addition to webmail via Group Office (yuck). dovecot-ldap.conf: # Include multiple domain controllers for redundancy, first one is # at the same facility as the Dovecot server. hosts = 10.0.1.12:389 10.0.2.12:389 10.0.3.12:389 # Specify the full DN of a user to authenticate against dn = cn=Internal, ou=People, dc=example, dc=com dnpass = some_secure_password auth_bind = yes ldap_version = 3 base = ou=People, dc=example, dc=com # Specify the base storage for email here user_attrs = sAMAccountName=home=/var/vmail/example.com/%$ # The following user_filter should all be on a single line. # The ugly userAccountControl param means "Exclude disabled users" user_filter = (&(sAMAccountName=%Ln)(!(userAccountControl:1.2.840.113556.1.4.803:=2))) pass_filter = (&(sAMAccountName=%Ln)(!(userAccountControl:1.2.840.113556.1.4.803:=2))) For the Postfix side of things, the article explains how to set Postfix to use Dovecot's SASL for authentication. It also specifies separate confs for Postfix to lookup users and aliases from. For my purposes, I decided not to modify the AD schema, and to instead utilize an unused field to store aliases in. This field had to be able to store multiple values in a way that I could query easily via LDAP. I chose the "IP Phone" field for this purpose. In the AD GUI it is easily accessible, and allows for multiple values to be stored. Note its usage in the queries that follow. /etc/postfix/ldap-users.cf: # Same list of DCs as in dovecot-ldap.conf server_host = ldap://10.0.1.12:389 ldap://10.0.2.12:389 ldap://10.0.3.12:389 search_base = dc=example, dc=com bind = yes bind_dn = EXAMPLE\internal bind_pw = a_secure_password # Use this lookup for email addresses matching the following domains # corresponds with virtal_mailbox_domains in main.cf domain = example.com, examplelegacy.com, exmple.com # The following query has been modified a bit from the above article. # First, the userAccountControl param specifies the exclusion of # disabled users. # The other change is from objectClass to objectCategory. query_filter = (&(&(objectCategory=person)(sAMAccountName=%u))(!(userAccountControl:1.2.840.113556.1.4.803:=2))) result_attribute = sAMAccountName version = 3 # I was having trouble with referrals not resolving properly due to a # misconfigured domain controller. I turned this option off and have # not had a problem since. chase_referrals = no result_format=example.com/%s/ debuglevel = 0 timeout = 30 /etc/postfix/ldap-aliases.cf: # Same list of DCs as in dovecot-ldap.conf server_host = ldap://10.0.1.12:389 ldap://10.0.2.12:389 ldap://10.0.3.12:389 search_base = dc=example, dc=com bind = yes bind_dn = EXAMPLE\internal bind_pw = a_secure_password domain = example.com, examplelegacy.com, exmple.com # This query looks up aliases from the otherIPPhone field. query_filter = (&(&(objectCategory=person)(|(otherIPPhone=%u)(sAMAccountName=%u)))(!(userAccountControl:1.2.840.113556.1.4.803:=2))) result_attribute = sAMAccountName version = 3 chase_referrals = no result_format=%s(a)example.com debuglevel = 0 timeout = 30 The objectCategory replacement for objectClass is a *huge* performance increase. objectClass is not indexed in Active Directory, forcing a lot of CPU cycles to be wasted for every lookup. The way I have implemented things, this means two of these expensive lookups per incoming email (even if it was undeliverable!). At first this was using around 50% CPU on a dual Xeon domain controller. This was acceptable at the time, but after my optimizations we were able to move authentication to a virtual machine with 640MB of RAM and a single CPU core where it now stays below 20% all day. Changing the lookup to an indexed field probably cut the initial load by 90%. Adding auth_cache settings to dovecot.conf then further reduced load by more than 50%. Well, I suppose that screed should suffice for my first post.

Re: [Dovecot] [RCU] Dovecot managesieve

Well I've looked forward into the wiki and did not found my server have only system users ( no virtual domain ) and the wiki says : System users If you wish you use deliver for all system users on a single domain mail host you can do it by editing mailbox_command parameter in /etc/postfix/main.cf (postconf(5)): That's what I did but then I have this problem with DOTLOCK If I chmod 777 /var/mail directory it works but I do not feel comfortable with that kind of access rights ...

[Dovecot] Capability COMPRESS implemented?
by Ed W 15 Feb '10

15 Feb '10

Hi, I just read that http://tools.ietf.org/html/rfc4978 ..is being implemented in Thunderbird 3. This is great news! It's been a long time since we last discussed this and I don't think it's currently implemented in Dovecot, but since Cyrus just added it, any chance of getting support in Dovecot please? (Fastmail seems to be supporting this effort) On a similar note we had a previous thread about supporting TLS deflate - any chance you could investigate this again and add support on the Dovecot side so at least it would be feasible to submit a bug fix on the Thunderbird side? (It looked like a one liner change back when we last discussed it?) Thanks Ed W (Obviously for those looking for an external high performance compressor you can use our compressing email proxy from http://www.mailasail.com ...)

[Dovecot] So, what about clustering and load balancing?
by Stefan Foerster 15 Feb '10

15 Feb '10

Hello world, so, with beta2 of Dovecot 2.0 being available, what is the preferred way to achieve load balancing and fault tolerance? As far as I can see it, there are basically two options: 1) Use a HA shared storage, export either a cluster filesystem or NFS, and have your dovecot servers mount that file system. Load balance these servers (Cisco ACE, ldirectord, ...) and there you go. Overall performance is limited by the speed of the shared storage and may further decrease due to locking issues, imperformant cluster filesystems and so on. 2) Set up every dovecot server with local storage and trigger a dsync after each change (pyinotfiy, incron, parse LMTP delivery logs, ...). Load balance these servers as before. Depending on the number of syncs that have to be done, mailbox replication may lag behind. The need to constantly spawn dsync processes may further decrease performance if you don't do it right (stickiness of established connections, replicating at most every xyz seconds). What are your opinions on that matter? Stefan P.S: I've set up option two in a test setup, though the incron/inotify part is still giving me a headache.

[Dovecot] POP3 with dovecot LDA and sieve
by Arthur Titeica 14 Feb '10

14 Feb '10

Hello. I'm using Postfix with Dovecot as IMAP, POP3 and LDA. With sieve rules I successfully move mails to specific mailboxes and this is great if accessing the account thru IMAP. However, when accessing thru POP3 I only get mails from Inbox. I wonder if it's possible to get real new mails, regardless of the folder they're in. Thanks for any thoughts. Arthur

[Dovecot] Virtual plugin and user_query
by Arthur Titeica 14 Feb '10

14 Feb '10

Hello, As per a previous reply regarding POP3 I'm now trying to configure the virtual plugin. However I don't really understand how to modify the sql user_query to properly indicate inbox=yes. I created 3 namespaces as per wiki instructions and I've modified the password and user queries as bellow: password_query = \ SELECT email, password, login , concat('*:bytes=', quota) \ AS userdb_quota_rule, \ CASE '%s' WHEN 'pop3' THEN NULL ELSE 'yes' \ END AS namespace_1_inbox, \ CASE '%s' WHEN 'pop3' THEN 'yes' ELSE NULL \ END AS namespace_2_inbox \ FROM users \ WHERE email = '%u' AND login = 'active' user_query = SELECT \ concat('*:bytes=', quota) AS quota_rule, \ CASE '%s' WHEN 'pop3' THEN NULL ELSE 'yes' \ END AS namespace_1_inbox, \ CASE '%s' WHEN 'pop3' THEN 'yes' ELSE NULL \ END AS namespace_2_inbox \ FROM users \ WHERE email = '%u' After that all I get in the logs is: IMAP(arthur(a)psw.ro): Error: namespace configuration error: inbox=yes namespace missing IMAP(arthur(a)psw.ro): Fatal: Namespace initialization failed As I don't really understand those case sql queries is there something I should add in the mysql tables? Any thoughts will be greatly appreciated. Thanks!

[Dovecot] deliver and cloning file permissions
by Alexander 'Leo' Bergolth 14 Feb '10

14 Feb '10

Hi! I'd like to use deliver (dovecot-1.2.10) as LDA to deliver mails to my local users on my postfix-system. However, deliver tries to copy the filesystem permissions of the mail-spool-files to the user's index files, which doesn't work, since the files in /var/mail/ belong to the group 'mail'. Feb 13 00:21:19 leo-x61 dovecot: deliver(leo): fchown(/home/leo/mail/.imap/INBOX/dovecot.index.log.newlock, -1, 12(mail)) failed: Operation not permitted (egid=100(users), group based on /var/mail/leo) I know that dovecot tries to clone the mailbox permissions in order to support shared folders but it would be nice if there was an option to disable this (or to just try it and ignore the fchown error). I could manually change group ownership of all mailboxes from mail to each user's primary group or set the mailbox-modes to 0600 but I'd also have to do that for every new user. (Tools to create users like useradd from shadow-utils use hardcoded file modes and group ownership.) Is there any workaround?

[Dovecot] Plugin question
by Valery Gorbunov 14 Feb '10

14 Feb '10

Hi All I needs to write plugin which converting messages by replacing entier message by one of parts of this message. In another words I need show part of multipart message instead entire message. Stream substitution in *mail->v.get_stream()* function gives incorrect results because mail indexed and cached before. Therefore I should wrap email during indexing too. something like: ----- struct index_transaction_context * it; it->ibox->mail_vfuncs->get_stream = convert_get_stream; ----- Is it enough or idea to replace mail stream by another will don't work anyway? Could you suggest how to show one mail instead another in Dovecot environment? Thank you Valery Gorbunov

Hi Folks, How scalable is dovecot. Do you think a machine with a dual core 2.8Ghz processor and 2GB of RAM would do a business with 600 users? This server will have a 100Mbps link to the net, however it will be access by the business using a couple of ADSL lines (Roughly 7Mbps each). This machine will also be running Postfix Your help is appreciated Cheers Jonny

I can browser all the way down to the folder, but I can't see anything within that folder. For example, consider the full path to the following 'Ashley-Dec09' mailbox: ~mail-Archives/2009/Ashley/Ashley-Dec09 In Thunderbird, when I hit 'Subscribe' I can browse down to '2009' and I can see 'Ashley', but I can't drill down into it and subscribe to 'Ashley-Jan09'.

[Dovecot] upgrade 1.0.15-2.3+lenny1 to 1.2.9-1~bpo50+1

System: Debian 5.0.4 Lenny Kernel: custom 2.6.31.1 built from kernel.org source Dovecot: 1.0.15-2.3+lenny1 Available: 1.2.9-1~bpo50+1 Mailbox format: mbox Storage location: /home/$user/mail/ on ext2 fs Delivery: Postfix 2.5.5 local to /var/mail/$user As you can see Debian has a backport package of Dovecot 1.2.9 available to Lenny users, and it appears it is a big jump forward in terms of elapsed time and codebase. Debian ships Dovecot in a collection of 6 packages. I currently only use two, dovecot-common and dovecot-imapd. I'm guessing it would probably be wise to shutdown all my current Dovecot processes before starting the upgrade. Before I do this upgrade I figured I'd ask first to see if there are any gotchas or explosions awaiting me. Any warnings, hints, pointers anyone? Timo? Thanks. -- Stan

[Dovecot] fts squat -> webmail, fastcgi timeout: SOLR the answer?
by mailinglists＠belfin.ch 11 Feb '10

11 Feb '10

Hi I turned on fts squat to speed up full text searches over webmail. This works absolutely fantastic once the mailboxes are indexed. But when they are indexed for the first time I'm getting a fastcgi timeout after 30 seconds resulting into a internal server error on the webserver. In the background the indexing job is getting finished after 80 seconds for a 25k emails, ~300MB mailbox. Does solr allow user-offline indexing (no user interaction needed to kick on indexing) ? And the other question is, is there any mail user agent that would support server-side full text indexing and not create own indexes? Thanks, Philipp

[Dovecot] Purging a large folder... anything I need to be careful of?
by Dave 10 Feb '10

10 Feb '10

I've got a large message folder (about 40G in 'cur') that I need to empty to a more reasonable size. Oddly, my Thunderbird e-mail client only sees about 2.4G of that, and has "looped" a few times. What I mean is, I thought someone was cleaning the folder out, but Thunderbird apparently was actually just looping back to 0 every 4 gigs and starting to count up again Ha. But that's a sidenote. So, since Thunderbird apparently is not seeing all of the messages, what is the safest way to delete the files straight from the 'cur' folder? IS that safe? Will I mess up any of the dovecot indexes in any way?? Dave

[Dovecot] Folders within folders ...
by Ashley M. Kirchner 10 Feb '10

10 Feb '10

Our mail setup is as follows: ~/mail/ - This contains single mailboxes (Drafts, Trash, and others) ~/mail-Archives/ - This contains a hierarchy of folders containing mailboxes For example, a tree of ~/mail/ would look like this: ~/mail/ ~/mail/Trash ~/mail/Drafts ~/mail/sent-mail ~/mail/My Stuff ~/mail/Important ~/mail/test/SomeFolder <-- this would never happen, but I have to account for it during our transition A tree of ~/mail-Archives/ would look like this: ~mail-Archives/2009/MyStuff/MyStuff-Dec09 ~mail-Archives/2009/MyStuff/MyStuff-Nov09 ~mail-Archives/2009/MyStuff/MyStuff-Oct09 ~mail-Archives/2010/MyStuff/MyStuff-Jan10 ~mail-Archives/2010/Important/Important-Jan10 All of that works, I can open up Thunderbird and browser/read/delete messages no problem. However, when I try to move that 'test' folder from ~/mail/ into ~/mail-Archives I get an error message: 'Can't rename mailbox to another storage type.' The same thing happens if I try to move any of the mailboxes in ~/mail/ to ~/mail-Archives/ . Is there a way to fix that? Our namespaces look like this: namespace private { separator = / prefix = "mail/" location = mbox:~/mail:INBOX=/var/mail/%u inbox = yes hidden = no list = yes # for v1.1+ } namespace private { separator = / prefix = "mail-Archives/" location = mbox:~/mail-Archives inbox = no hidden = no list = yes subscriptions = yes }

[Dovecot] Dovecot and duplicates
by Veikko "Wexi" Skurnik 10 Feb '10

10 Feb '10

Hi I'm having a problem setting up duplicate filtering on my mail server. I've set up the mail server with Postfix and Dovecot with virtual LDAP users, ClamAV virus scanning. The problem is that some of the virtual users use multiple e-mail addresses and postfix delivers emails sent to a user as many times as the user has email address entries in LDAP. I was wondering what would be the smartest way to get rid of these duplicates, they have identical message ID:s and a simple procmail recipe does the trick, however as I'm using dovecots deliver, procmail isn't the answer. Is it possible to use Sieve to do this, I've been googling around *a lot* and haven't found anything that would solve the problem... This is the procmail recipe that succesfully eliminates the duplicates: MAILDIR=/var/vmail :0 Wh: msgid.lock | formail -D 8192 .msgid.cache Or could another solution be to configure postfix to first receive the email, then let procmail do the duplicate filtering, then ClamAV does the virus scan and finally dovecots deliver delivers the message to the virtual user's mailbox? Any help will be greatly appreciated =) Wexi -- * Veikko "Wexi" Skurnik: +358(44)5288338 * * wexi(a)wexin.net Wexi@IRCNet * * Näyttämönkatu 4 B 12 33720 Tampere * * "Kosminen balanssi ei saa järkkyä" *

I'm running KDC with all users and passwords, but have to manage clients who doesn't support GSSAPI like mobile phones. Is it possible to dovecot SASL check password in KDC when user sends plain text login? I know this is possible to do with saslauthd from Cyrus but prefer to stick with dovecot SASL.

[Dovecot] Converting layouts
by Luciano Mannucci 09 Feb '10

09 Feb '10

Hello, I'm using dovecot 1.2.10 with mbox format (which implies layout=fs) and I would like to switch to maildir++ layout without changing format in order to implement subfolders for IMAP users. I understand that I should move the INDEX location to avoid some namespace conflict (it would be a good idea anyway: I'll move them on another disc :). Now I have mail_location = mbox:/var/spool/mailboxes/%u:INBOX=/var/spool/mail/%u in my /etc/dovecot.conf. I think it should become somethink like mail_location=mbox:/var/spool/mailboxes/%u:LAYOUT=Maildir++:INBOX=/var/spool/mail/%u:INDEX=/var/dovecot_indexes I'll have to rename folders for IMAP users, right? Is there some script that does just that? Some other needed black magic for .subscriptions? Thanks to all in advance, Luciano. -- /"\ /Via A.

[Dovecot] Problem with created ~/mail directory
by Chris Adams 08 Feb '10

08 Feb '10

If a user doesn't have a ~/mail directory and logs in, the directory is created for them. However, it is created with insecure permissions, 0770 (full group access). The problem is this bit in src/lib-storage/index/mbox/mbox-storage.c: #define CREATE_MODE 0770 /* umask() should limit it more */ The code then uses CREATE_MODE as an argument to mkdir_parents(), but mkdir_parents() overrides the umask setting and forces the requested permissions. There's no way to override this except to change the source code. It looks like the same thing is in dbox-storage.c and cydir-storage.c. This is with Dovecot 1.2.10. -- Chris Adams <cmadams(a)hiwaay.net> Systems and Network Administrator - HiWAAY Internet Services I don't speak for anybody but myself - that's enough trouble.

[Dovecot] LMTP in 2.0: concurrency, inet sockets
by Stefan Foerster 07 Feb '10

07 Feb '10

I didn't really have much time to look at the beta versions of dovecot 2.0 (apart from installing it once and migrating most of my current configuration, purely for testing purposes). An exciting new feature is the LMTP support. In the default configuration I have seen, that one only listened on a Unix socket - will it support network (inet) sockets, too? What about concurrent deliviers? As of now, when using the deliver LDA together with Postfix, you have to make sure that only one recipient is passed to deliver at a time, so for multi-recipient mail, the system might spawn a large number of processes (two per recipient, therefore two forks/execve calls). Is that limit still imposed with the new LMTP server? Stefan

[Dovecot] blocked for xx secs

Hello, Occasionally (a few times a day) we get batches of Warnings in the log such as: dovecot: Warning: chdir(/maildir/x.co.uk/users/y) blocked for 18 secs This tends to last a minute or so for different users. /maildir is a NFS mount, and I'm suspecting it's the NFS server being busy and dovecot having to wait. Other than replacing the NFS server with faster hardware is there anything else we can do? Indexes are local, and Maildir is on the NFS. Dovecot 1.2.5 using: mail_nfs_storage = yes mmap_disable = no NFS mounted as; /maildir on /.automount/a.diskless/root/mail type nfs (nosuid,nodev,noatime,vers=3,proto=tcp) TIA -- Andrew

[Dovecot] pop3 quick question
by Nikita Koshikov 06 Feb '10

06 Feb '10

Hello list, I have found imap_allowed option in dovecot which do exactly what I need, for imap. Is there something similar for pop3 protocol? The main goal for it - is to enable pop3 access to specific users. Or maybe dovecot have some 'pop3=yes' or 'imap=no' args to userdb/passdb sections ? I know future dovecot 2.* versions will support rewriting for protocols, but this is required for 1.2 branch.

Re: [Dovecot] mdbox compression
by Damon Atkins 06 Feb '10

06 Feb '10

ZFS has support for compression on the file system ( lzjb | gzip | gzip-N | zle ). gzip eats CPU even at levels as low as 3. From the zfs man page The lzjb compression algorithm is optimized for performance while providing decent data compression. You can specify the gzip level by using the value gzip-N where N is an integer from 1 (fastest) to 9 (best compression ratio). The cost of CPU to support compression (gzip) vs the Cost of Disk if mboxes are not compressed? The other interesting feature ZFS (OpenSolaris) has is de-duplication, it detects if the block which is about to be written, is the same as another block and instead of writing the block it puts a pointer to the already existing block, saving disk space. Only problem with this is you would need to filter out headers which are different even when the to/body is the same. Cheers

[Dovecot] mdbox compression
by Timo Sirainen 06 Feb '10

06 Feb '10

I was wondering if I should add compression support to mdbox one mail at a time or one file (~2MB) at a time. The tradeoffs are: * one mail at a time allows quickly seeking to wanted mail inside the file, but it can't compress mails as well * one file at a time compresses better, but seeking is slow because it can only be done by uncompressing all the data until the wanted offset is reached I did a quick test for this with 27 MB of my old INBOX mails: (note the -b option, so it doesn't count wasted fs space) mdbox/storage% du -sb . 15120350 . Maildir/cur% du -sb . 16517320 . % echo 1-15120350/16517320|bc -l .08457606924125705623 So, compressed mdboxes take 8.5% less space. This was with regular gzip compression with default level. With bzip2 -9 compression the difference was 10%. Any thoughts on if 8-10% is significant enough improvement to make seeking performance worse? Or perhaps I should just implement both ways.. :)

[Dovecot] Forcibly emptying a POP3 mailbox
by Răzvan Sandu 05 Feb '10

05 Feb '10

Hello, I've recently saw a discussion on this list, about a standardised way of emptying POP3 mailboxes on the server - but no solution came up. Please provide a suggestion for the following situation: - I am running a stock POP3 dovecot server, on Fedora 12 (dovecot version 1.2.9) - passwd-file authentication via /etc/imap.passwd - users are virtual, sharing the same UID/GID; - storage is in MailDir system; - for remote users, server is POP3-only, since the administrative policy says that every user should download his messages on the local workstation, then delete them from server immediately after succesful download. - IMAP is allowed only locally, in order to be used together via stock squirrelmail Web interface (for emergencies only) However, there are users that check the infamous „Leave a copy on the server” checkbox (or equivalent) in their mail clients, eventually adding „Delete messages after X days”. Since I have no direct administrative control on the clients, I absolutely need a way to forbid the above behaviour at server level, in order to enforce the policy. The server's HDD is meant to store received messages from reception to the first access only. Filesystem quotas are not an option in this scenario, since the UID/GID is the same for all virtual users. What I need is way to make sure that "cur" and "tmp" subdirectories are perfectly empty after the user downloads his mail. (I will also need a way to make sure that users using squirrelmail leave no populated "Sent" and "Trash" folders on server's HDD, but that's offtopic here). Could you please suggest a way to solve this ? Thanks a lot, Răzvan

Hello, Thanks a lot, but the problem here are not the IMAP users accessing the server via squirrelmail. Few people use this. What I mainly want to avoid are *POP3* users checking the „Leave a copy on the server” checkmark. I need a way of automatically performing the DELE command at server level, just after a POP3 user *succesfully* downloaded his messages via POP3... Thanks again, Răzvan

[Dovecot] postfix and dovecot on different systems - sasl request
by thomas polnik 05 Feb '10

05 Feb '10

Hello, until now I have use postfix and dovecot on the same server. Now I want/must split this both systems (server1 - postfix, server2 - dovecot). I used dovecot auth system for postfix ## snip ## smtpd_sasl_type = dovecot smtpd_sasl_path = private/auth ## snap ## but this does not work, if dovecot is not running on the same server. I did not find any information in postfix/dovecot documentation, how I could solve this problem smart. My only idea, but it looks like quick and dirty solution: On the postfix system a small dovecot systems runs only for postfix sasl via /var/spool/postfix/private/auth. (Or I use saslauthd with sql or imap) The postfix system (on server 1) delivers mails via transport map to the dovecot system. On the dovecot system postfix delivers this mails i.e. via ## snip ## dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/deliver -d ${recipient} ## snip ## to the mail boxes. Are there other ways, how I could solve this problem? My wish configuration: postfix sends the auth request via tcp/ip to the dovecot auth system and not via a socket. I use postfix 2.6 and dovecot 1.2.6. Best regards, thomas polnik.

[Dovecot] Fatal: chdir( ) failed: Permission denied

Hi Dovecot fails to chdir() into users home directory giving the following error: Oct 9 16:43:49 jura dovecot: dovecot: Fatal: chdir(/a/home/mina) failed: Permission denied (euid=1118 0(mina) egid=11332(devel) missing +x perm: /a/home) Oct 9 16:43:49 jura dovecot: dovecot: child 14441 (imap) returned error 89 (Fatal failure) The reason seems to be that user primary group is "devel" and directory /a/home has ACL which gives execute permission only to the users in "domain users" group. Now the catch is that the user _is_ member of "domain users" group and is happily accessing his home directory over CIFS(Samba) for long time. Also, the user has no problem entering his home directory when using shell access. It just seems like the user lost membership of a bunch of supplementary groups. The group membership info is coming from M$ PDC via winbind and NSS. We have few users and can change the users primary group and/or relax the /a/home directory ACL, but overall this is not right. Shall I shut up or can we hope for a fix or at least explanation?

[Dovecot] Question re: storing non mail files via IMAP
by Charles Marcus 05 Feb '10

05 Feb '10

Hey Timo, I have a question regarding how dovecot might behave if a mail client (like, for example, Thunderbird) decided to store some of its config files on the IMAP server itself. Would there be a decent way of doing this with dovecot that wouldn't cause problems for other clients that didn't know about these files? Maybe there's a way to define a special folder that dovecot knows about at the top level of each users mail location that can be used for this kind of thing? All I'm thinking of are certain config related files, so they would be small, and would only be downloaded when they didn't already exist - ie, when someone adds their existing account to a new PC, the first time they logged in, TB could simply download all of the config files, restart itself, and voila, your pre-configured TB is ready to go...

Only client knows, so only client may act. In that case, the only possibility is to have some automatic script that periodically "cleans" the "cur" subdirectories, as you suggested. However, not being a programmer at all, I'm far from being able to write an industrial-grade solution for this. ;-) Best regards, Răzvan

@Pascal Volk Thanks for the algorithm you've provided ! Unfortuantely, I'm not a programmer myself and I don't feel confident to code such an utility (even if I perfectly understand your pseudocode). ;-) What I'm looking for is not even a hand-made script, but a production solution included in the stock dovecot RPM package itself - i.e a new, better form of the dovecotpw utility.

[Dovecot] Execute mailfilter after message move
by Kārlis Repsons 04 Feb '10

04 Feb '10

Hi, came here to ask, if there are any ideas about a possible Dovecot feature, which would allow execution of a specific mailfilter or other program after new message is *moved* in specified mail location? The practical benefit on my side would be, that there wouldn't be any need to do getmail cronjobs, which unnecessarily fill up logfiles... (primarily for easy spam learning and reporting)

[Dovecot] [dovecot] Problem with namespaces and dovecot -n
by Jonathan Siegle 03 Feb '10

03 Feb '10

I'm running dovecot 2.0 revision 10622:de9d6dae7fe5 on AIX. I'm trying to see both namespaces that I have listed in mail.conf. namespace private { separator = / prefix = inbox = no hidden = no location = maildir:%h/Maildir list = yes } namespace private { separator = / prefix = "#mbox/" location = mbox:%h:INBOX=/var/mail/%u inbox = yes hidden = no list = yes # for v1.1+ } Whichever namespace is last, I can see when running dovecot -n. Am I supposed to only see the last one printed? # 2.0.beta2: /usr/local/dovecot2.0beta2/etc/dovecot/dovecot.conf # OS: AIX 3 0001112AD300 auth_debug = yes auth_gssapi_hostname = $ALL auth_krb5_keytab = /etc/krb5/dovecot.keytab auth_mechanisms = plain gssapi disable_plaintext_auth = no listen = * login_greeting = Dovecot version 2 on tr27n12 ready. mail_full_filesystem_access = yes mail_location = mbox:%h:INBOX=/var/spool/mail/%Ju/%u mbox_lazy_writes = no mbox_write_locks = fcntl mmap_disable = yes namespace { hidden = no inbox = yes list = yes location = mbox:%h:INBOX=/var/mail/%u prefix = #mbox/ separator = / name = private } passdb { deny = no driver = pam master = no pass = no } With this config I have no folders. If I flip the namespaces in the config, I have no INBOX and can't login. Thanks, Jonathan

[Dovecot] [RFE] A way to encode passwords in the /etc/imap.passwd file
by Răzvan Sandu 03 Feb '10

03 Feb '10

Hello, Is this the proper place to suggest an enhancement for the stock dovecot package ? The enhancement would be the following: For the time being, the dovecotpw utility offers a standardised way to interactively encode a user password in a certain scheme, say: dovecotpw -s CRYPT Enter new passord: Re-enter new password: etc. Given a *valid* /etc/imap.passwd file (passwd-file authentication), dovecotpw should be able to process it non-interactively and output another text file with all {PLAIN} passwords converted in the specified <scheme>, i.e.: dovecotpwd -s CRYPT if=/etc/imap.passwd of=/etc/imap.passwd.converted where /etc/imap.passwd.converted have the previously {PLAIN} passwords converted in scheme CRYPT. Passwords that were previously encrypted in other schemes than {PLAIN} shoud remain untouched. That will allow quick securing of old legacy /etc/imap.passwd files. Thanks a lot, Răzvan

[Dovecot] deny=yes in userdb
by Edgar Fuß 03 Feb '10

03 Feb '10

I would like deliver to reject certain users. Since supposedly deliver only uses userdb, not passwd, I can't use deny=yes for that. Or does userdb support deny=yes? Yes, I should rather reject them right in the MTA, but that currently takes too long to implement. Or how to reject gast* in postfix using nss authentication?

[Dovecot] disabling mail delivery for a user
by Frank Cusack 02 Feb '10

02 Feb '10

How can I disable mail delivery for a user yet still allow access to their mailbox from another account which their mail is shared to? If I put them in a userdb which has "deny = yes" that just disables their ability to login, yes? And they would still have mail delivered. I want to disable their ability to login AND bounce all mail delivered to them, preferably solely through dovecot configuration. I am using lda, obviously, for mail delivery. (I could configure the MTA to reject mail for them if there is no other option.)

[Dovecot] v2.0.beta2 released
by Timo Sirainen 02 Feb '10

02 Feb '10

http://dovecot.org/releases/2.0/beta/dovecot-2.0.beta2.tar.gz http://dovecot.org/releases/2.0/beta/dovecot-2.0.beta2.tar.gz.sig I tried to keep the configuration and APIs compatible with v2.0.beta1, but unfortunately there were a few things that really had to be changed: 1. passdbs and userdbs have now a separate "driver" setting inside them. So for example if you had: userdb passwd { } You'll now need to use instead: userdb { driver = passwd } 2. Services now have default inet_listeners. You need to either remove your existing ones, or override the defaults by giving the listeners's name like shown in the new example master.conf. For example if you had: service imap-login { inet_listener { port = 1234 .. change it to: service imap-login { inet_listener imap { port = 1234 If you want to disable a default listener, you can set its port to 0. Some new features: - Added auth_verbose_passwords = no|plain|sha1. If authentication fails, this setting logs the used password. If you don't really need to know what the password itself was, but are more interested in knowing if the user is simply trying to use the wrong password every single time or if it's a brute force attack, you can set this to "sha1" and only the SHA1 of the password is logged. That's enough to know if the password is same or different between login attempts. - lazy-expunge: Support a single-namespace configuration. In this setup if mailbox has some expunged messages and then the whole mailbox gets deleted, they get merged into the same deleted mailbox. - protocol !imap { .. } adds configuration to all protocols except imap. - imap/pop3 proxying supports now async DNS lookups for hosts. There's a separate dns-client service doing the lookups using OS's own blocking resolver. - dovecot-config file changed in a way that it'll be easier to create external software linking against dovecot libraries. This made Pigeonhole's configure script a lot simpler. And of course there have been lots of fixes.

[Dovecot] proxy_maybe regex
by David Halik 02 Feb '10

02 Feb '10

Does anyone know if dovecot support regex lookups for proxy/proxy_maybe, rather than mysql/ldap etc? I've been comparing it with perdition to see which one might be better for us to do layer7 username switching. Perdition supports the ability to not have any auth/db looks, but rather just a regex file that parses the usernames as they come in and forwards to the particular machine on the same port. For example: username:host ^[a-d]: 192.168.xxx.1 ^[e-k]: 192.168.xxx.2 and so on... I didn't think this was supported in dovecot, but I wanted to check first. I think this is going to end up being what we use to avoid NFS problems. It's lightweight, drops into our current setup, and doesn't require a mysql database which adds another point of failure. -- ================================ David Halik System Administrator OIT-CSS Rutgers University dhalik(a)jla.rutgers.edu ================================

[Dovecot] Want to have some users with Maildir, some with mbox
by Stewart Dean 02 Feb '10

02 Feb '10

Want to have some users with Maildir, some with mbox, as I migrate from mbox format to maildir over the space of a month. After everyone is converted to maildir, I'll change the mail_location in dovecot.conf. During the interim, can I use the Custom mailbox location script (at the bottom of the Mail Location DC Wiki page)? > if [ -d $HOME/.maildir ]; then > export MAIL=maildir:$HOME/.maildir > else > export MAIL=mbox:$HOME/mail:INBOX=/var/mail/$USER > fi > Questions: 1) What does explicitly specifying MAIL this way override? The dovecot.conf mail_location variable? 2) My mail_location var is defined as: mail_location: mbox:~/mail:INBOX=/var/spool/mail/%u:INDEX=/var/dcindx/%u and my prospective maildir INBOX and mail folder root is to be ~/Maildir. So would I change the above to: > if [ -d $HOME/Maildir ]; then > export MAIL=maildir:$HOME/Maildir:INDEX=/var/dcindx/$USER > else > export MAIL=mbox:$HOME/mail:INBOX=/var/spool/mail/$USER: > INDEX=/var/dcindx/$USER > fi Question 3: When converting existing users from mbox to maildir, should I delete the index contents?

[Dovecot] index location
by Dave Brenner 01 Feb '10

01 Feb '10

Greetings. We are testing with 1.2.9 and have found that with mail_full_filesystem_access set to 'yes', we cannot force indexes for folders under ~/mail to be stored in /var/dovecot/indexes/%u. /var/dovecot/indexes/%u/.imap/INBOX/dovecot.index* is created just fine, but everything else ends up in ~mail/.imap. If I change mail_full_filesystem_access to 'no', then all indexes are created in the expected location: $ ls -la /var/dovecot/indexes/blitz/ total 4 drwxr-xr-x 4 blitz popuser 512 Jan 25 11:46 . drwxrwxr-x 5 root popuser 512 Jan 22 16:16 .. drwxr-xr-x 3 blitz popuser 512 Jan 22 16:16 .imap drwxr-xr-x 3 blitz popuser 512 Jan 25 11:46 mail (I probably need to set the sticky bit for this, but for testing this is OK) We are setting the index location from /etc/passwd-dove: blitz:x:14267:500::/usr/users/dialups/blitz::userdb_mail=mbox:~/:INBOX=/var/mail/%u:INDEX=/var/dovecot/indexes/%u Is there a way to get this to function the way we'd like, with all indexes stored in /var/dovecot/indexes/u% ? My apologies if I missed an explanation about this in the list archive. Dave

[Dovecot] Extraneous information

Not technically a bug, but a small waste of bandwidth: it seems (at least as of 1.2.10) that if neither CONDSTORE/QRESYNC are enabled dovecot still sends HIGHESTMODSEQ info: a examine Testing.AAA * FLAGS (\Answered \Flagged \Deleted \Seen \Draft $Forwarded impflag0 impflag1 impflag2) * OK [PERMANENTFLAGS ()] Read-only mailbox. * 309 EXISTS * 0 RECENT * OK [UNSEEN 5] First unseen. * OK [UIDVALIDITY 1225053009] UIDs valid * OK [UIDNEXT 387] Predicted next UID * OK [HIGHESTMODSEQ 136] Highest a OK [READ-ONLY] Select completed. I'm guessing this would only happen if using a client that supports QRESYNC (like IMP) and then switching later to a client that doesn't support.

[Dovecot] Not understanding namespaces
by Stewart Dean 01 Feb '10

01 Feb '10

I have been diligently reading about namespace in the DC doc and what I can find in Google. Like the blind men and the elephant, I see the nature of some individual bits of namespace, some syntax and the overall purpose (overriding defaults and providing extensions), but I don't see the whole thing and how it is used. I am looking to do some maildir testing in what is a mbox default system, so I thought to employ namespace to do so. I see that namespace(s) can be defined in dovecot.conf and I see that it can be defined in TBird (under ServerSettings, Advanced Account Settings), but it isn't clear to me how they are made to work together. Some questions: - Is it that you can define multiple namespaces in dovecot.conf and then specify which of these you use in the TBird server settings? - What is the syntax of the TBird namespace specification? -- ==== Once upon a time, the Internet was a friendly, neighbors-helping-neighbors small town, and no one locked their doors.

[Dovecot] sha-512 ... shadow blended with database
by WJCarpenter 31 Jan '10

31 Jan '10

The cryptic subject is the outcome of my looking into how to do a particular thing. I wonder if anyone else has solved this problem in a way that hasn't occurred to me. I'm using dovecot 1.1.11 on Ubuntu Server 9.10. I could consider upgrading to my own install of a newer dovecot if it made a difference to this problem. I have two populations of dovecot users. Some users have Unix accounts (with logins disabled), and so their password hashes are stored in /etc/shadow. These days, the default configuration for that is salted SHA-512. It's easy for me to change that scheme to something else if I want to, but the important fact is that I already have some users with passwords in salted SHA-512. The other population of users is purely virtual, and their password hashes are stored in a MySQL database in SHA-1 format (unsalted, but moving to salted wouldn't be a big deal). The database also has a column identifying the hash scheme, so SHA-1 isn't some assumption. I know that I have have multiple passdb in my dovecot config, but I'm looking to unify my two user populations and put them all in the MySQL database. As far as I can tell from the wiki, there is no SHA-512 in any version of dovecot. MySQL also doesn't have SHA-512. So, I don't see a way of reworking my password checking to accomodate the salted SHA-512 values currently in /etc/shadow. I'd prefer to not ask the SHA-512 users to update their passwords for this administrative reason if I can avoid it (but so far, that looks like the only answer). Any ideas?

[Dovecot] Recommended method?
by Brandon Lamb 30 Jan '10

30 Jan '10

Hopefully this isnt TOO general of a question. I have a raid server that runs dovecot and exports via nfs the maildir format store. I have 4 mail servers running exim that use dovecot to deliver over nfs I have been examing our entire setup and had the thought, would it be recommended to instead have another exim process running directly on the raid server and have my mail servers deliver mail to that rather than over nfs, if that makes sense? So mail would go from our postini frontend => mail cluster => final delivery via exim on raid server. Seems like this way I could make all the nfs config options go away and such. Thoughts?

[Dovecot] Pigeon hole sieve binaries and dovecot header install
by Mark Washenberger 30 Jan '10

30 Jan '10

Stephan, I've recently been playing around with packaging dovecot 2.0 and dovecot-2.0-pigeonhole, as well as the --enable-header-install configure options of both. This lead me to the following question. Should pigeonhole's sieve binaries rely on static libstorage / other dovecot libraries? It seems like they should instead use shared libraries, but I couldn't find a configure option to make this happen. That way, I could break my packages up like so: dovecot dovecot-devel libdovecot dovecot-pigeonhole dovecot-pigeonhole-devel And while pigeonhole/sieve might require libdovecot to run, it shouldn't require it to compile. Thoughts? I can provide a lot more detail about my compilation errors if you think its necessary.

[Dovecot] Does anyone know a good Dovecot hoster in europe?
by Johannes 30 Jan '10

30 Jan '10

Hi, though I am not sure this is the right place to ask, but I just try. I am looking for a better e-mail hoster providing me with a dovecot server (I don't want to do all the admin stuff and backup myself, if possible). I already googled a bit, searched the archives and had a look at dovecot.org but could not find an answer to this question. Since dovecot seems to get a fair amount of funding from finnish companies I thought there should be a good hoster among them. Any hints? Thanks Johannes

[Dovecot] Authentication failure (password mismatch?)

I setup dovecot on my laptop to practice on. I was following some of the information on this page: https://help.ubuntu.com/community/PostfixVirtualMailBoxClamSmtpHowto#Testing Your Setup I created the in this format: user:{plain}pass:1000:1000::/home/user::userdb_mail=maildir:~/Maildir for userdb passwd-file. I used smart for the user and wade for the password (its just for testing) and then attempted to log into the system.

[Dovecot] Dovecot SSL issues
by Spyros Tsiolis 29 Jan '10

29 Jan '10

Hello all, successfully managed to make dovecot work with horde (http://www.horde.org) and another MTA (SMTP/POP3). I have this nagging issue with dovecot though (I suspect - it's dovecot and not the rest of the packages, please read on): There is this special page one goes, that check if everything is ok with all the relevant software running along Horde. It's a php file called "test.php". Now, this file shows almost everything that happens in the box. Here's a transcript of what shows when it comes to dovecot and SSL : --------------------------- * Trying protocol imap/ssl, Port 993: ERROR - The server returned the following error message: SECURITY PROBLEM: insecure server advertised AUTH=PLAINCertificate failure for localhost: self signed certificate: /C=GR/ST=Kerkyra/L=Kerkyra/O=The Company Name/OU=IMAP server/CN=webmail.thecompanyname.gr/emailAddress=postmaster(a)webmail.thecompanyname.gr --------------------------- From what I understand, it doesn't like the certificate. However, I've followed a howto document step-by-step and did what is documented. Does anyone have any pointers on how to make secure imap for dovecot ? E.G. on ThunderBird, the settings are the following : Tools -> Account Settings -> Server Settings : Server Name : (the server or its ip address) Username : (the username) Port : (I've manually entered "993", because by default goes to "143") Security Settings -> Connection Security : SSL/TLS (again manually entered) CHECK_ON : Use secure authentication Now, if I click on "Get Mail" button on top of the TB window, I get a pop-up window with the following message : ------ Server : Location : <Servers' IP Address>:993 Certificate Status : This site attempts to identify itself with invalid information. Wrong Site : Certificate belongs to a different site, which could indicate an identity theft. Unknown Identity : Certificate is not trusted, because it hasn't been verified by a recognized authority. ------ After that, the users accepts the above by pressing ok twice. However, there's a third pop-up window with a message shown below : ------ You cannot log in to <servers' ip address> because you have enabled secure authentication and this serer does not support it. To log in, turn off secure authentication for this account. ------ Any help would be appreciated.. Thank you all for your patience, S. Tsiolis

[Dovecot] mdbox, dsync
by Timo Sirainen 29 Jan '10

29 Jan '10

I finally migrated my mails from mbox format to mdbox format using dsync: 1. Stop dovecot, wait a few seconds for processes to die 2. dsync convert mdbox:~/mdbox 3. Change mail_location to mdbox:~/mdbox 4. Check that no new mails arrived during conversion (alternatively I could have just run dsync again, but I decided not to test my luck) 5. Start dovecot After fixing a pretty bad bug in dsync and a couple of other unrelated bugs, everything seemed to work correctly and transparently. UIDs and everything was preserved as expected. I think I even feel my mail clients being faster than with mbox :) ~% du --exclude=.imap -bsh mail-old-mbox 707M mail-old-mbox ~% du -bsh mdbox/* 27M mdbox/mailboxes 704M mdbox/storage The reason why I'm giving -b is because without it, mdbox was a lot larger than mbox (734 MB vs. 710 MB). I guess this is because zfs internally decided to waste some space for the files. ~/mdbox/storage% ls -lS -rw------- 1 tss tss 13602413 2010-01-29 18:05 m.68 -rw------- 1 tss tss 10487382 2010-01-29 18:06 m.209 -rw------- 1 tss tss 7749964 2010-01-29 18:06 m.270 -rw------- 1 tss tss 7493010 2010-01-29 18:05 m.69 .. -rw------- 1 tss tss 2097246 2010-01-29 18:06 m.175 -rw------- 1 tss tss 2097213 2010-01-29 18:06 m.151 -rw------- 1 tss tss 2097173 2010-01-29 18:06 m.197 -rw------- 1 tss tss 2097163 2010-01-29 18:05 m.89 -rw------- 1 tss tss 1307164 2010-01-29 18:33 m.296 Total of 296 files. The reason why there are a few large files is because their last mail is huge. I guess in future mdbox should try to avoid doing that if it knows the mail's size beforehand. Actually I thought it already tried to do that.. Anyway, let's hope it doesn't now corrupt all my mails.

[Dovecot] dovecot auth feature request
by Frank Cusack 29 Jan '10

29 Jan '10

when i try to run dovecot for SASL support only, with literally just this configuration: protocols = none ssl = no auth default { mechanisms = plain login passdb passwd-file { args = /etc/dovecot/passwd } socket listen { client { path = /var/spool/postfix/private/auth mode = 0660 } } } I get this: Error: ssl_cert_file: Can't use /etc/ssl/certs/dovecot.pem: No such file or directory Since, in this configuration, SSL doesn't have meaning, dovecot shouldn't be looking for any cert file. Easily fixed with "ssl = no" but that shouldn't be required. -frank

[Dovecot] mailbox format w/ separate headers/data
by Frank Cusack 29 Jan '10

29 Jan '10

In the future, it would be cool if there were a mailbox format (dbox2?) where mail headers and each mime part were stored in separate files. This would enable the zfs dedup feature to be used to maximum benefit. In the zfs filesystem, there is a dedup feature which stores only 1 copy of duplicate blocks. In a normal mail file, the headers will be different for each recipient and the chances of the content of the message being able to be dedup'd are close to zero, because the differences in header length changes the block boundaries for the rest of the message. But if each mime part is stored in a separate file, you get massive compression "for free". -frank

[Dovecot] Courier-to-Dovecot-migration: Outlook downloads all Mails again
by Werner 29 Jan '10

29 Jan '10

Hi everybody, I'm currently playing through the migration from Courier to dovecot. I've converted the User's Maildir with 'courier-dovecot-migrate.pl'. Outlook 2003 is configured to access the Mailbox via POP3, the option "Leave a copy of messages on the server" is activated. But: after the migration Outlook 2000 redownloads all mails again :-( Could it be, that Outlook 2000 "thinks" (after changing the POP3/SMTP-Server in the Outlook configuration pointing to my testsystem) this is a new system and starts to download the messages again? If so, Outlook 2000 won't download all messages again if we do the migration because POP3/SMTP-Server remains the same. Can anybody confirm this? We do not experience this issue with Thunderbird for example. Thank you, Werner

Hello List, we use in our system cryptical Usernames for dovecot etc. and authenticate users against shadow/passwd User abcde is loging in and gets data from /var/spool/mail/abcde and /home/popuser/abcde Now we want to make it possible that users can log in also with emailadresses. I tried dovecot-mysql authentication which works fine but i do not find a way to use 2 different login-formats in my queries. login with abcde and also testname(a)example.com should return ok and lead to /var/spool/mail/abcde. Is this possible or i have to make a decision which format to use? Thanks, Andre

Just a notice to those of you who use Dovecot authentication with Exim. In Dovecot 2.0 authentication server will send a new keyword, COOKIE. This will cause Exim to abort it's authentication request. I submitted a bug and patch to Exim to fix this, the patch is here: http://km.krot.org/code/exim-dovecot-1.1.diff BR, Kirill

[Dovecot] virtual mailbox / INTHREAD use case, issues, questions
by David Abrahams 27 Jan '10

27 Jan '10

For over a year now, I've been trying to acquire the ability to review the thread history of a message in my INBOX while still deleting messages as soon as I believe I'm done with them. Suddenly I'm gratified to see that several approaches have been right under my nose all along! One is the INTHREAD imap extension, which I see is implemented by dovecot. Another (related) is dovecot's virtual folders. When I saw the GMail-style "conversation view" described at http://wiki.dovecot.org/Plugins/Virtual I was elated, so I tried it out, with exactly that configuration (almost -- my separator is '.'). I ran into several problems (using Dovecot 1.2.8 with http://hg.dovecot.org/dovecot-1.2/rev/9cccb8617820 applied): 1. I had to manually create the virtual folder for all my users or they couldn't access their mail at all. Is this fixed in 2.0? 2. My users were getting errors when accessing via POP3. The possible meaning of such a virtual folder under POP3 is lost on me, but I had to enable the virtual plugin for that protocol too. I think that should at least be in the documentation, or better yet the requirement should that it be enabled for POP3 should be dropped. 3. I couldn't get the virtual "conversation view" inbox to show any messages. But maybe that's because of a possible issue I describe below with x-mailbox 4. At some point I ended up with an empty mailbox called "private.virtual" --- I have no idea how. Probably user error. 5. The "all" virtual mailbox would only show 89 messages. I switched it to be a mirror of my "archive" mailbox and the number started to look more reasonable. This could be the "lots of mailboxes" bug describe in http://dovecot.org/list/dovecot-news/2009-December/000145.html 6. I got the impression that looking at the virtual INBOX didn't cause the "all" mailbox to be updated, which I'd guess that it should be. 7. I tried to create an IMAP search, rather than a virtual folder, that looked for x-mailbox INBOX header like the virtual folder does. It too came up empty. It doesn't exactly surprise me because I don't see an x-mailbox header in any of these messages. In fact, I can't find one in /any/ of my messages. When I look for a description of the x-mailbox header, I don't find much information on where it comes from or what it represents. http://www.dovecot.org/list/dovecot/2009-June/040619.html seems to indicate it's synthesized by the server. If it's really supposed to represent the message's "original" mailbox as implied by http://wiki.dovecot.org/Plugins/Virtual then I'm not sure what that means for messages that are filed twice by sieve and never moved. Lastly, I want to report that for me, the speed of these IMAP searches doesn't begin to approach what I can do with mairix if I want a message's entire thread. I'm happy to use mairix, although it would be nicer not to duplicate that capability if it's already in the server. But it needs to be fast. Is there something I can do to make it go faster? Thanks in advance for any advice, hints, fixes, workarounds, etc. -- Dave Abrahams Meet me at BoostCon: http://www.boostcon.com BoostPro Computing http://www.boostpro.com

Looks like my bugfix exposed yet another bug. Your script worked previously because the removeflag command did not work properly. With 0.1.15 I fixed the removeflag command, thus breaking your script. The essence of the bug we face now is that for the deprecated imapflags extension (that you are using now) only the flag state at the end of the script is used for storing messages. This is now fixed: http://hg.rename-it.nl/dovecot-1.2-sieve/rev/a890258aa5a9 You can work around this issue by substituting "imapflags" with "imap4flags" in the script above. I've added some proper tests to the test suite to prevent this problem from re-occuring in the future. Regards, Stephan.

[Dovecot] STATUS command and total/read message count
by Florian Effenberger 27 Jan '10

27 Jan '10

Hello, I'm running Dovecot 1.0.15 with Thunderbird 3.0.1. TB can query folders for messages in two ways: Either by using the STATUS command, or by opening the folder (don't know the respective IMAP commands, sorry...). Querying via opening the folder is reliable, but via the STATUS command, only new/unread messages are shown. If I want to have the total number of (unread) mesages in a folder, I have to manually open it, so the headers are loaded. Is this a Dovecot issue, or a problem with Thunderbird? In other words: Does the STATUS command only return new/unread messages, or can this be configured on the server side? Thanks, Florian

[Dovecot] Plugin
by Alex Baule 27 Jan '10

27 Jan '10

Hello Everyone... Some time ago, i send some questions about plugins and concat 2 file handles. So, there is another questions about this. Timo Sirainen send to me this modification, in src/lib-storage/index/maildir/maildir-mail.c struct istream *full_input[3]; full_input[0] = i_stream_create_fd(fd, 0, TRUE); full_input[1] = i_stream_create_fd(fd1, 0, TRUE); full_input[2] = NULL; input = i_stream_create_concat(full_ input); This is necessary because my Header and Body is splited. This modification works fine. My question is: There is a way to do this with a plugin ? I dont know how to implement this in a plugin, because i dont know what is the hook to change the maildir_open_mail functions. (this is the function with the modification above) . Another question is: There is a seek function, in dovecot, and in zlib plugin, it is rewrite by another function, that use the "gzseek" to do the seek. My splited body will be encrypted, and the crypto no have seek, because the message will be encrypted. (if i open the message, decrypt and seek to some position, maybe work). The seek function is really necessary to IMAP and maildir ?

[Dovecot] read-only dovecot-uidlist

Hi all, i just investigated a user complaint and found a read-only dovecot-uidlist. Since dovecot couldnt write it, the process failed. Users can not reach this file, so how this became readonly is beyond me. Must be something in dovecot. Maybe an older bug? Doing a search now for more readonly uidlist files, but that'll take a few hours. Cor

[Dovecot] dovecot-antispam for dovecot 2.0?
by Adam Seering 26 Jan '10

Hi, Just wondering, is there a development version or the like of the dovecot-antispam plugin, that works with the Dovecot 2.0 beta? I'm starting to poke at the new version (mdbox looks really handy for my use case); I'm also starting to play with dspam, but I'm finding it annoying to train dspam without it having direct access to my (rather-large existing) spam folder... Thanks, Adam

[Dovecot] acl flag to limit imap_acl based acl changes
by Amon Ott 26 Jan '10

26 Jan '10

Hi all! I have tried the imap_acl plugin with 1.2.9 today, but was not able to limit acl changes for those mailboxes where acl changes should be forbidden. http://wiki.dovecot.org/ACL says that "a" or "admin" covers "Administration rights to the mailbox". However, removing "a" from owner acl (using "lr") does not help, the user can still change all acl flags for all users with imap. Write accesses to mails are forbidden as they should. Is this intended or a bug? We would like to give all users the ability to use ACLs through IMAP, but the current behaviour endangers our read-only mail archives.

[Dovecot] Released Pigeonhole Sieve v0.1.15 and ManageSieve v0.11.11 for Dovecot v1.2.10
by Stephan Bosch 25 Jan '10

25 Jan '10

Hello Dovecot users, It's been a while since the last Pigeonhole Sieve and ManageSieve releases. That is why this release includes quite a few changes. Most interestingly, the include extension is updated to match the most recent specification, the Sieve interpreter now includes plugin support and ManageSieve now has support for enforcing quota on the size of scripts, the number of scripts and the space the scripts occupy on disk. Other than that, quite a few small bugs were fixed. One of which was in the i;ascii-numeric comparator. If one of the matched strings did not start with a digit, the comparator would always yield a 'less-than' result. In stead it should have considered the string starting with the non-digit character as having a positive infinite value. Elsewhere in this list, Julian Cowley pointed out that negative values also start with a non-digit character, which some people may not have understood (i.e. i;ascii-numeric works only on unsigned values). The bug fix in this release could therefore change result of certain misconceived (and probably spam-related) Sieve rules, so watch out! I started work on the spamtest(plus) and virustest extensions. These are implemented for the most part, but their configurability needs quite a bit more work. Changelog Sieve v0.1.15: * Enotify extension: - Adjusted notify method API for addition of new notification methods. - Set default importance level to 'normal' (was 'high'). * Include extension: updated implementation towards most recent specification (all should be backwards compatible): - Implemented global variables namespace. - Global command may now appear anywhere in a script. - Implemented script name checking using the requirements specified in the ManageSieve draft. - One issue remains: ManageSieve currently requires included scripts to be uploaded first, which is not according to specification. * Changed envelope path parser to allow to and from envelope addresses that have no domain part. + Added preliminary support for Sieve plugins and added support for installing Sieve development headers. + Started work on the implementation of the spamtest, spamtestplus and virustest extensions (unfinished). + Deprecated notify extension: implemented denotify command. + Variables extension: added support for variable namespaces. + Added configurable script size limit. Compiler will refuse to compile files larger than sieve_max_script_size. + Testsuite changes: - Added support for changing and testing an extension's configuration. - Added a command line parameter for copying errors to stderr. - Fixed a bug in the i;ascii-numeric comparator. If one of the strings started with a non-digit character, the comparator would always yield less-than. - Imap4flags extension: fixed bug in removeflag: removing a single flag failed due to off-by-one error (bug report by Julian Cowley). - Improved EACCES error messages for stat() and lstat() syscalls and slightly improved error messages that may uccur when saving a binary. - Vacation extension: fixed typo in runtime log message (patch by Julian Cowley). - Fixed use of minus '-' in man pages; it is now properly escaped. - Fixed parser recovery. In particular cases it would trigger spurious errors after an initial valid error and sometimes additional errors were inappropriately ignored. Changelog ManageSieve v0.11.11: * This release contains adjustments to match changes in the Sieve API. This means that this release will only compile against Pigeonhole Sieve v0.1.15. + Implemented ManageSieve QUOTA enforcement. + Added MAXREDIRECTS capability after login. + Implemented new script name rules specified in most recent ManageSieve draft. - Fixed assertion failure occuring with challenge-response SASL mechanisms. - Made configure complain about trying to compile against installed Dovecot headers alone. - Fixed compile warning for compilation against CMUSieve. The releases are available as follows: Sieve: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.15.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.15.tar.gz.sig ManageSieve (package + patch): http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.11.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.11.tar.gz.… http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.10-managesieve-0.11.11.diff… http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.10-managesieve-0.11.11.diff… Refer to http://pigeonhole.dovecot.org for more information.

[Dovecot] Delete messages with archivemail
by gstyle 25 Jan '10

25 Jan '10

Hi, I have set up a dovecot imap server (Version 1.0.15 on Debain Lenny). Until know I used courier. Every night I run a script calling archivemail ( http://archivemail.sourceforge.net/) to delete all messages in the Spam folder that are older than 30 days archivemail deletes the files directly in the Maildir folder. I am not using IMAP for this (cause I don't want to store the passwords in plain text). I know that dovecot uses index files to speed up Maildir access. Will there be any problems with the index files when I delete the old spam like this? Cheers Mario

[Dovecot] pop3+leave messages on server
by Papp Tamas 24 Jan '10

24 Jan '10

hi All, I have a srange problem. Before dovecot there was a courier imap and it worked just fine. The client(s) are the same then before, so I think, this is an server side problem. I have a user with Outlook and he uses pop3 and leaves messages on server. Sometimes the messages get downloaded again, when he starts the outlook. Not all, but 7-9 hours back. uidl format is like it's suggested: pop3_uidl_format = %08Xu%08Xv Any idea, what's wrong and what I can do? Thank you very much, tamas

[Dovecot] strange behaviour with seen/unseen messages in virtual folders.
by Matthias Rieber 24 Jan '10

24 Jan '10

Hi, I've a virtual folder that contains unseen messages. When I mark the message and expunge the folder, the message should disappear. This works as expected in alpine. Alpine uses the following commands: 06000010 STORE 1 +Flags (\SEEN) 06000020 EXPUNGE Using roundcube mail, the message wont disappear, when I perform the same steps. RoundCube Mails sends: flg UID STORE 445 +FLAGS (\Seen) exp1 EXPUNGE But the message doesn't dissapear. But I can expunge it with alpine, as long as the folder contains one message. If it contains more messages, some or even all messages won't disappear. When I mark them as unseen/seen in alpine, I can expunge them with alpine. The expunge command send by roundcube mail never expunges any seen message in the unseen folder. Whether it was flagged as seen by alpine nor roundcube mail. kind regards, matthias

[Dovecot] Need simplest method for providing alternate mail location
by Stewart Dean 24 Jan '10

24 Jan '10

I am looking to migrate my DC V1.2 from mbox to maildir format....and want to do this in stages, user group by user group rather than in one horrendous fell swoop....since I'd rather fell things didn't happen. Since I'm running sendmail/procmail, I can change the ~/.procmailrc to change the writing of the INBOX, but the IMAP mail location access info is knottier when one wants to do things a bit at a time. Setting aside for now the matter of converting existing folders, I will be moving: = from a mbox setup with the INBOX in /var/spool/mail/<userid> and the folders in ~/mail = to both in ~/Maildir (unless someone has better ideas) It seems that one could: 1) Change the namespaces in the client...but this is not feasible, because it would means going out to all my 4000+ users desktop and modifying them. 2) Having some sort of db to tell DC it a mail_userdb extra field and override the mail_location in dovecot.conf 3) Perhaps waiting for DC v2.0 which will have this architected in. A) Is there any sense the v2.0 will be coming Real Soon Now and will fulfill #3? B) What's the simplest way to implement #2? I would really rather not install MySQL on my mail server and have all the overhead of installing and managing it when all I need it for is a temporary resource to tell DC where things are until the switchover is complete and Maildir is the default. Is it feasible to do this with an additional flat file in the /etc/passwd mode with some extra fields tacked on that is *only* used for mail location info? Or some other and simple way? My apologies if this is a Stupid Question............. -- ==== Once upon a time, the Internet was a friendly, neighbors-helping-neighbors small town, and no one locked their doors.

[Dovecot] SpamAssassin and i;ascii-numeric comparator
by Julian Cowley 24 Jan '10

24 Jan '10

Hi Stephan, I noticed that you changed i;ascii-numeric comparator recently (<http://hg.rename-it.nl/dovecot-1.2-sieve/rev/17fb38aee85f>) to correct a small bug. I have an interest in this because I use the comparator to check for SpamAssassin scores. Before the fix, this was all that was necessary to check for scores above a certain value: header :value "ge" :comparator "i;ascii-numeric" "X-Spam-Score" "5" Since SpamAssassin includes negative scores and the i;ascii-numeric comparator doesn't recognize negative numbers, all negative scores are actually treated as positive infinity after the fix. Of course, this means mail which has a negative score then gets counted as spam. Now an additional test is necessary, something like this: allof(not header :matches "X-Spam-Score" "-*", header :value "ge" :comparator "i;ascii-numeric" "X-Spam-Score" "5") I thought I'd mention this because other people may get affected by this once 0.1.15 comes out. Here is a patch that makes further tests for the comparator between numeric and non-numeric values. Hope you can use it. -=- julian

[Dovecot] how to create maildir on local mail delivery
by Sebastian Logar 24 Jan '10

24 Jan '10

Hi! I am using Dovecot 1.0.10 with LDA/postfix option reading user data from ldap, but the problem would be nonexistent maildir. Connection with ldap should be fine since reading proper maildir folder.

[Dovecot] feature question: local delivery from SMTP

Does Dovecot really need a separate MTA for inbound mail? Or can it receive SMTP directly if there is no forwarding to do? What about spam/virus filtering in that case? -- Phil Howard KA9WGN - ka9wgn(a)gmail.com

[Dovecot] Mail process plans: multiple connections in a process + idle processes
by Timo Sirainen 23 Jan '10

23 Jan '10

Maybe for v2.1: imap and pop3 processes can currently handle multiple connections, but they're assigned pretty much randomly to processes. It would be better if it was possible to: a) Require that a process handles only a specific user's connections b) Require that a process handles only a specific UNIX UID's connections (e.g. if each domain has a separate UID) c) Prefer to put user's connections to same process, but don't require it. To do this, there needs to be a process between imap/pop3-login and imap/pop3. Let's call it imap/pop3-tracker process (or aggregator? or any suggestions?). This process accepts all connections coming from login processes when they've finished authenticating a connection. Internally it figures out if the connection should go to a new or an existing process. It keeps track of username -> { mail_process[], cookie (see idle processes below) } mail_process -> { unix_socket_fd, connection_count } So there's a connection to each mail process. This connection is used to send connection fds for the process to handle. It's also used to receive notifications when a connection is closed. The mail process sockets could also be used to communicate to a specific process. For example doveadm could use this in future to ask what a specific user or process is currently doing, by connecting to imap-tracker, which forwards the request to wanted process(es). The above isn't really anything new, just a more specific plan about what I had been thinking for a long time. A new and more interesting idea is to gather IDLEing imap connections under a few imap-idle processes: When a connection has been IDLEing for a few minutes (or something), and there's no special state in the connection (e.g. CONTEXT=SEARCH searches), the connection could be moved to a separate imap-idle process that simply waits for something to happen. When something does happen, it'll move the connection back to imap process, which restores state and continues. The idea would be to reduce the number of idling imap processes that are wasting memory. The state that needs to be saved and restored is: - selected mailbox name, GUID, UIDVALIDITY (for reliably selecting back the original mailbox, or reliably fail if it's gone) - flag: mailbox is EXAMINEd, not SELECTed - highest seen modseq - UIDs of \Recent messages - SEARCHRES extension: last saved SEARCH result - List of keywords that had been advertised in FLAGS/PERMANENTFLAGS reply to client. Or probably MD5 sum of it would be enough. If MD5 had changed, the list would be re-sent to client. - connection fd - paths that are being monitored with [id]notify/kqueue Connection is moved back when a) new command is received from connection fd, b) one of the monitored files changes. The connections are moved back via imap-tracker process, by sending the saved state along the request. For security there's a per-user security cookie (128 bits of randomness), which is sent to imap processes, and when restoring connection from imap-idle, the request must provide the correct cookie or imap-tracker fails the login. (Normally new post-login imap/pop3 connections can't be created without having authenticated first via dovecot-auth. They verify it.) So when connection comes back, imap process opens the mailbox based on saved information. If this fails for some reason (e.g. mailbox deleted), client gets disconnected. Next Dovecot gets a list of changes to mailbox since the saved modseq, and based on that sends the missing FETCH, EXPUNGE, EXISTS and RECENT events. Again if it somehow fails, the client gets disconnected. At least initially this would only be done for connections that are running IDLE command, because non-IDLE connections are a lot more difficult to restore to their original state. This is mainly because if a message gets expunged, it's still visible to the connection until it issues a command that allows sending EXPUNGE event. To handle that, there would have to be code that allows building a view of mailbox where there are some expunged messages. Also it can be difficult to find out the expunged messages' flags, unless they're also part of the saved state.

[Dovecot] format of file dict
by Frank Cusack 22 Jan '10

22 Jan '10

For shared (between users) mailboxes, I am using a file dict. plugin { acl_shared_dict = file:/etc/dovecot/acl_shared_dict/shared.db } What is the format of this file? I would like to manage it directly rather than have SETACL update it. I see lines which describe a sharing entry (the format of those looks obvious) but also lines with just a '1'. Do I just need to separate entries by lines with just '1' in them? -frank

[Dovecot] Thinderbird+delete+move to Trash folder
by Papp Tamás 22 Jan '10

22 Jan '10

hi All, I have a problem, which makes me headache. I can't find out, what is the problem. I have a mail szerver, which works just fine as expected, TB move messages to trash folder after I delete it, and they are moved. I have an other server. If I delete a message, it doesn't move to the Trash folder. As deleted_to_trash plugin is installed, if I only mark messages as deleted, they are moved to thee Trash folder and also with Outlook works well. It's like when a messages is deleted from TB, the message get moved to the Trash folder, and it's expunged(?) at the same time. Is it possible? Could you help me? The system is Ubuntu 9.04 with docecot 1.2.5-0~auto+0 from http://xi.rename-it.nl/debian/, but builded by myself for x86_64. Thank you, tamas

[Dovecot] Modifying the underlying maildir externally (webmail, replication)
by Attila Nagy 22 Jan '10

22 Jan '10

Hello, I have a setup where there are multiple maildir users, one of them being the pop/imap server itself, the others are for example a maildir capable webmail and message replication. I would like to evaluate Dovecot, but I wonder how would its binary indexes and logs fit into this picture. After running through http://wiki.dovecot.org/IndexFiles I'm not sure how well would Dovecot work with other programs modifying the maildirs (adding, deleting, moving messages, folders etc). The "Main index" section says "The index file is synchronized against mailbox only if the syncing information changes.", where syncing information consists or cur and new directories' timestamps. Does that mean I am safe there? The cache file is hopefully just a cache, so it won't contain information from messages which are inserted or moved by an external program, and I assume Dovecot fetches the message lists and other information from the main index, which seems to be OK. The transaction log is for the main index, so if the latter is OK, the former should be OK too. http://wiki.dovecot.org/MailboxFormat/Maildir talks about MUAs and there nothing scary can be found, except for some temporary conditions, where the changes won't propagate to Dovecot in real time, but it's OK. Are the above right, and can Dovecot use its indexes and caches safely with others using the same maildirs? Thanks,

Hi folks, Is there some config file option to switch off CONDSTORE support? Of course I checked the manual on the Wiki, but I haven't seen CONDSTORE mentioned at all. Forgive me if I am too blind to see. Many thanx Harri

[Dovecot] Files Moving From /New to /Cur
by Tony Rutherford 22 Jan '10

22 Jan '10

Using Dovecot 1.2-9 with Maildir and layout=FS. We have our own delivery pushing messages to the /new and then /cur folder eventually. When I have an IMAP client attached, there is apparently some sort of race going on. I believe that Dovecot is moving files from /new to /cur (and renaming them) before our own delivery gets the job done. This is causing a problem for us. Is there a way to disable this in Dovecot? I have the LDA section commented out of the config file..so I don't think that's in play. Bottom line is that I don't want Dovecot to move any files around whether an IMAP client is attached or not (except for handling the IMAP COPY/APPEND). Regards, Tony

[Dovecot] Conditionally use a sieve script with deliver?
by Kārlis Repsons 22 Jan '10

22 Jan '10

I found a post in this list [0], which says sieve scripts can be used to deliver mail as read. However, can it be done somehow conditionally, I mean, with a direct or indirect switch for deliver? For a nonexistent example, it would be simply < | deliver -m path/to/maildir -r > or maybe an environment variable could be exported to deliver sieve and checked there? (Still not sure if sieve can replace maildrop in my case, however, using it with dovecot creates various problems with interoperability; but perhaps I can just add those imap4flags like "\\seen" myself to the message with maildrop and avoid mess with sieve at all?)

[Dovecot] IDLE timing issue - dovecot or fetchmail issue?
by Matt Doran 22 Jan '10

22 Jan '10

Hi guys, Thanks for the great product. We've used dovecot for ages as our internal mail server and it works great! I've recently started using fetchmail 6.3.9 (with IDLE enabled) to download mail from our ISP (Pair networks). The ISP is running Dovecot 1.1.16. I am unable to get the info about the dovecot config at this time. The IDLE support in fetchmail allows us to deliver mail near instantaneously without the need to poll (which is what we did previously using POP3). However I've noticed an issue where if 2 mails are delivered in quick succession fetchmail will only download the first email, and the second will not download. If I then send in another test email this triggers the download of 2 emails (the original that wasn't downloaded and the test email). Now I'm wondering whether the issue lies with Dovecot (e.g. a timing issue), or is it fetchmail that isn't implementing the IDLE/download properly. I've attached the output of a fetchmail session showing this problem in action (I've added some annotations to this file starting with >>>>>). The sequence of events are: * Start fetchmail with IDLE enabled * Send 2 emails in quick succession. * Dovecot notifies of the new message * Fetchmail downloads the message * Fetchmail initiates a new IDLE * Then nothing more is delivered. :( * I then send another email, which triggers the 2 to download. I don't know enough about IMAP to understand whether the problem lies with Dovecot or Fetchmail. Hopefully an IMAP expert will be able to see from the attached IMAP session.

[Dovecot] IMAP only for some users or via webmail
by Federico Tomasczik 22 Jan '10

22 Jan '10

Hello! First, sorry for my English... I'm a newbie with Dovecot and I have some questions, I'm testing Dovecot 1.1.11 in a virtual machine. I wish in the future, migrate this to a real server. Ok, but i need this: 1) A group of users can use IMAP or POP3. 2) The others, only can use POP3. But, this users can use IMAP only with a webmail (the webmail is in the same server that Dovecot) It is possible? How? Thanks! Federico Ch. Tomasczik

[Dovecot] nologin in auth proto version 1.1
by Kirill Miazine 21 Jan '10

21 Jan '10

I notice that the nologin parameter for the AUTH command is gone in version 1.1 of Dovecot Authentication Protocol. nologin was added in 1.1, so that authentication client could indicate that there will be no subsequent master requests to retrieve user info. Could we have nologin back please? Kirill

[Dovecot] Fastest restart of dovecot after upgrade: HOW?:
by Ralf Hildebrandt 21 Jan '10

21 Jan '10

I'm running dovecot under runit: #!/bin/sh echo '/var/core/%p' > /proc/sys/kernel/core_pattern ulimit -n 8096 ulimit -c unlimited exec /usr/local/sbin/dovecot -F (that way, together with incron, I can automatically generate the coredumps I'm posting all the time) If I apply a patch and recompile, what is the fastest way of restarting dovecot?

[Dovecot] Maildir and IMAP keywords
by Per-Erik Persson 21 Jan '10

21 Jan '10

When a user in thunderbird toggles some flags like junk, spam or something similar dovecot appends these flags form a-z to the end of the file in maildir. I have another application that also access the maildirs which gets really upset with these flags and ignore those emails. Are there any other way for dovecot to store these flags to make it compatible with other softwares?

[Dovecot] Migration from Courier to dovecot
by Werner Detter 21 Jan '10

21 Jan '10

hi list, I've just registered to the list, so please be tolerant ;) I'm currently in the process of planning the migration from courier to dovecot as POP/IMAP-Server. I'm migration from Courier 0.58 (Debian-Etch-packages) to Dovecot 1.1.13 (Debian Lenny Backport). The conversion of the Mailbox from Courier to Dovecot will be done with "courier-dovecot-migrate.pl"-script[1], which works fine. However after running "courier-dovecot-migrate.pl" the Courier-Files still remain in the Maildir. Can i just delete those Courier-specific-files or does dovecot need them somehow (do you normally get rid of these after conversion)? It's about these files: courierimapacl courierimapsubscribed courierimapuiddb courierpop3dsizelist And those directories: courierimaphieracl courierimaphieracl Can i simply delete those with "find" ? Furthermore: is it possible to convert back from Dovecot-Format to Courier-Format? Thanks in advance, Werner [1] http://www.dovecot.org/tools/courier-dovecot-migrate.pl

[Dovecot] MUA notifications on new mail in a new folder?
by Kārlis Repsons 20 Jan '10

20 Jan '10

If deliver gets run with a non-root userid like this: < | deliver -m path/to/NEWmaildir >, I wonder, is a connected IMAP MUA automatically notified, that the new message has arrived in the new folder? As I see from some experiments with Thunderbird, it has no problems with immediate notifications of new mail in previously existing folders, however, it has problems with the case of new folder.

[Dovecot] outlook 2007 can't see public folders more than 1 deep
by Frank Cusack 20 Jan '10

20 Jan '10

dovecot-1.2.9 I have a public folder using ACLs to determine who can access it. namespace public { separator = / prefix = shared/ location = maildir:/var/maildir/shared subscriptions = no } Outlook 2007 can't see any folders except at the top level. It can create them just fine, but can't see them after quit and restart. For example, I can create the folder shared/foo/bar but on restart outlook only sees foo as a folder without subfolders (no + to expand it) and doesn't see bar anymore. In fact I can delete the folder foo in outlook and then BOTH .foo and .foo.bar directories are removed on the server. When you click on foo, the error message in the mail pane is "Cannot display the folder. The folder 'foo' cannot contain items. This is most likely a limitation of your IMAP server. In order to create a folder that can contain items, be sure not to append '/' to its name as you create it." -frank

[Dovecot] md5_verify(...): Not a valid MD5-CRYPT or PLAIN-MD5 password
by BaQs 20 Jan '10

20 Jan '10

'afternoon list! I use mysql as userdb, which contains two type of password schemes: DES and MD5-CRYPT. I read there : http://wiki.dovecot.org/Authentication/PasswordSchemes that both are supported by dovecot. Unfortunately, dovecot keeps saying: Not a valid MD5-CRYPT or PLAIN-MD5 password when looking for a user with DES encrypted password. Is dovecot able to recognize password scheme, or do I have to do something else ? I can't add {DES} to DES passwords, as this database is used with many other softwares. Thanks a lot for your help Pierre

[Dovecot] Two different issues with dovecot 1.1.13
by Stuart Rowan 20 Jan '10

20 Jan '10

Hi Timo, I'm using Debian backports.org dovecot-imapd, 1:1.1.13-2~bpo50+1. I've got two different issues, a reoccurring, seemingly harmless one about "Corrupted index cache file" (boring.txt) and one that went bonkers over the least few days (bt.txt) causing much spamming of the logs. I've made bt.txt stop happening by just rm'ing dovecot.index* : find Maildir/ -type f -name 'dovecot.index*' -print0 | xargs -0r rm ... which I realise may not be the most helpful thing to have done from your point of view. Anyway I just wanted to let you know about both of these. If one or both are already known about or already fixed by a later version of Dovecot, great and sorry for the noise! If not, and you want any more information etc., let me know. Many thanks, Stu. dovecot: 2009-07-28 10:23:16 Error: IMAP(strr): Corrupted index cache file /home/local/strr/Maildir/dovecot.index.cache: record continues outside its allocated size dovecot: 2009-07-28 10:23:56 Error: IMAP(strr): Corrupted index cache file /home/local/strr/Maildir/dovecot.index.cache: record continues outside its allocated size dovecot: 2009-07-28 08:05:54 Panic: IMAP(strr): file index-mail-headers.c: line 77 (index_mail_parse_header_finish): assertion failed: ((match[match_idx] & HEADER_MAT CH_FLAG_FOUND) == 0) dovecot: 2009-07-28 08:05:54 Error: IMAP(strr): Raw backtrace: imap [0x48dbf2] -> imap [0x48dc73] -> imap [0x48d346] -> imap(index_mail_parse_header+0x617) [0x4545f7] -> imap [0x483284] -> imap [0x483478] -> imap(i_stream_read+0x2c) [0x491d7c] -> imap(i_stream_read_data+0x46) [0x491f16] -> imap(message_get_body_size+0x108) [0x4885 a8] -> imap [0x4226c3] -> imap(imap_fetch+0x162) [0x420852] -> imap(cmd_fetch+0x23c) [0x41a27c] -> imap [0x41e46c] -> imap [0x41e51d] -> imap [0x41eb25] -> imap(clien t_input+0x63) [0x41efd3] -> imap(io_loop_handler_run+0xcb) [0x49515b] -> imap(io_loop_run+0x18) [0x4945c8] -> imap(main+0x3da) [0x426bea] -> /lib/libc.so.6(__libc_sta rt_main+0xe6) [0x7f0e851941a6] -> imap [0x418859] dovecot: 2009-07-28 08:05:54 Error: child 20007 (imap) killed with signal 6 (core dumps disabled) dovecot: 2009-07-28 08:05:56 Panic: IMAP(strr): file index-mail-headers.c: line 77 (index_mail_parse_header_finish): assertion failed: ((match[match_idx] & HEADER_MAT CH_FLAG_FOUND) == 0) dovecot: 2009-07-28 08:05:56 Error: IMAP(strr): Raw backtrace: imap [0x48dbf2] -> imap [0x48dc73] -> imap [0x48d346] -> imap(index_mail_parse_header+0x617) [0x4545f7] -> imap [0x483284] -> imap [0x483478] -> imap(i_stream_read+0x2c) [0x491d7c] -> imap(i_stream_read_data+0x46) [0x491f16] -> imap(message_get_body_size+0x108) [0x4885 a8] -> imap [0x4226c3] -> imap(imap_fetch+0x162) [0x420852] -> imap(cmd_fetch+0x23c) [0x41a27c] -> imap [0x41e46c] -> imap [0x41e51d] -> imap [0x41eb25] -> imap(clien t_input+0x63) [0x41efd3] -> imap(io_loop_handler_run+0xcb) [0x49515b] -> imap(io_loop_run+0x18) [0x4945c8] -> imap(main+0x3da) [0x426bea] -> /lib/libc.so.6(__libc_sta rt_main+0xe6) [0x7f2edf08b1a6] -> imap [0x418859] dovecot: 2009-07-28 08:05:56 Error: child 20984 (imap) killed with signal 6 (core dumps disabled)

[Dovecot] Autobuilder packages for Debian stable/i386 now available
by Stephan Bosch 20 Jan '10

20 Jan '10

Hi, A few days back I started the first automated slave builder that produces bleeding edge Debian stable packages for Dovecot v1.2 and v2.0. It uses the source packages already provided by the automated master repository (which builds binary packages for Debian testing), so that the version numbers and content are equal throughout all Debian releases. The repository is available as follows: deb http://xi.rename-it.nl/debian/ stable-auto/dovecot-1.2 main Or, for Dovecot v2.0: deb http://xi.rename-it.nl/debian/ stable-auto/dovecot-2.0 main Read this for more information: http://wiki.dovecot.org/PrebuiltBinaries#Automatically_Built_Packages I hope to add amd64 binary support soon. Regards, Stephan.

Re: [Dovecot] Oracle SQL driver

I've corrected the transaction handling mechanism. The only thing I couldn't understand: why rollback() shouldn't need to make real ROLLBACK? In case when whole transaction was failed succeded statements will remain uncommited. Then they will be commited later on next successful transaction. May be ROLLBACK is still needed? > The "VARCHAR sqltext[2048]" seems like an unnecessary restriction on the > query length. Wasn't there a way to do this without the limit? Or in AFAIK there is no possibility to use C types in PREPARE statement. Also Oracle cannot handle unsized VARCHARs. I've increased VARCHAR size to 65535. > test_connection() seems unnecessary. Right you are. > Couldn't driver_oracle_generate_name() be simply: > static unsigned int counter = 0; > return i_strdup_printf("ORACONN_%x", ++counter); =) Right. > driver_oracle_escape_string() really should be escaping the string. I made this function to replace single quote in string with two single quotes. IMHO this should be enough. How do you think? > Kind of annoying that each query needs a cursor, even though nearly all > queries are expected to return only a single row, but I guess that can't > be helped with the current API.. Yes. There are no other ways to work with untyped statements in OCI. But Oracle claims that all these statements shouldn't produce significant performance impact. The new version attached.

Re: [Dovecot] How can I configure dovecot as gmail imap proxy
by Supratik Goswami 20 Jan '10

20 Jan '10

Here the proxy server should authenticate the user. If the user is in the list of authenticated users then dovecot will allow to connect to imap.gmail.com. Consider a scenario where a client tries to read his mailbox from imap.gmail.com:993. Client executes the command "mutt -f imaps://imap.gmail.com", the request is first authenticated at the proxy server. If the request is coming from a valid user, dovecot will allow to connect to imap.gmail.com and fetch mails for that user. Can you please help me with the steps to configure the server.

[Dovecot] LDA and POP3/IMAP user_query
by Michael 20 Jan '10

20 Jan '10

How do I get IMAP+POP3 vs. LDA to use different user_query statements? The problem is that the input fields are different. IMAP/POP3 is an email address LDA is a username I have written a long statement to try and cater for both however it still only works 99% of the time, and the remaining 1% fails. The 1% that fails sees the mail being delivered to the wrong mbox. In this particular case the same client owned both mboxes so it was ok, but if this had not been the case things could have gotten real embarrassing. Think of the following: abcwidgets(a)theirdomain.tld mailuser1 mailuser1(a)adomain.tld mailuser2 Now when using the Postfix LDA, email for each address is properly delivered to the specified mbox, however in this case because their is a matching name for the mbox and the email address lefthand content, the compound SQL query returns both results and the LDA will use the first one, which in this case was the wrong one. This is the query used: user_query = \ SELECT mailboxes.username AS user, mailboxes.uid, mailboxes.gid, \ concat('*:storage=',mailquota,'M') AS quota_rule \ FROM mailboxes JOIN accounts ON accounts.username = mailboxes.username \ WHERE ((mailboxes.username = '%n' AND accounts.active='1') || \ (mailboxes.email = '%u' AND mailboxes.active='1' AND accounts.active='1') || \ (mailboxes.email = CONCAT('@','%d') AND mailboxes.active='1' \ AND (SELECT COUNT(email) FROM mailboxes WHERE email='%u') = '0')) which additionally caters for the few catch alls our users have. I think this is a massive oversight in the design of Dovecot to use one query to for 2 separate and distinct processes, that both use different parameters. From what I can tell it seems to assume that a mail system will always use username@domain addresses, and never anything more arbitrary. Has anyone found a way around this? Michael

[Dovecot] shared namespaces with common prefix prefix
by Frank Cusack 19 Jan '10

19 Jan '10

Can shared/public namespaces' prefixes have a common prefix? :) namespace public { separator = / prefix = zz/shared/ location = maildir:/var/maildir/shared:INDEX=/var/maildir/%n/shared subscriptions = no } # to share other employees mailboxes (term'd or admin access) namespace shared { separator = / prefix = zz/shared/%%u/ location = maildir:/var/maildir/%%n:INDEX=/var/maildir/users/%%u subscriptions = no list = children } Since I added the shared namespace, I can no longer access the public namespace. The folders show up but then trying to access one gets the error that the mailbox doesn't exist. If they can't have a common part of the prefix, is that an IMAP limitation or could dovecot conceivably handle it? -frank
