[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-

[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

Hello, I'm currently running 1.1.20 and I'm planning to upgrade to 1.2.10 I've read carefully the wiki page "Upgrading Dovecot v1.1 to v1.2" and a few messages concerning mail_location parameter but I still don't know what to change in my configuration in order to keep it working after the upgrade. I'm using mbox format and mbox_snarf plugin. dovecot -n : protocols: imaps pop3 pop3s listen: * ssl_cert_file: /etc/pki/tls/certs/ipop3d.pem ssl_key_file: /etc/pki/tls/certs/ipop3d.pem login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login mail_privileged_group: mail mail_gid: 12 mail_location: mbox:~/mail:INBOX=/var/spool/mail/%u mbox_lazy_writes: no mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugins(default): mbox_snarf mail_plugins(imap): mbox_snarf mail_plugins(pop3): mail_plugin_dir(default): /usr/lib64/dovecot/imap mail_plugin_dir(imap): /usr/lib64/dovecot/imap mail_plugin_dir(pop3): /usr/lib64/dovecot/pop3 lda: postmaster_address: postmaster(a)example.com auth default: debug: yes passdb: driver: pam userdb: driver: passwd plugin: mbox_snarf: %h/mail/INBOX Any help would be appreciated.

[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
by Lazy 18 Feb '10

18 Feb '10

Helloo, We are using dovectot lda with qmail-ldap, dovecot 1.2.10, sieve 0.1.15 lda is executed as exec /var/qmail/bin/preline -f /usr/local/dovecot/libexec/dovecot/deliver -s preline adds Delivered-To: header, everything works fine except vacation Feb 9 16:07:16 thebe dovecot: deliver(lazy): sieve: msgid=unspecified: discarding vacation response for message implicitly delivered to <lazy(a)thebe.org> Feb 9 16:07:16 thebe dovecot: deliver(lazy): sieve: msgid=unspecified: stored mail into mailbox 'INBOX' thebe.org is the hostname of the machine, oryginal recipient address has other domain .dovecot.sieve file looks like this require ["vacation"]; #autoresponder vacation :days 1 :subject "Auto Reply / Odpowiedz automatyczna" "aaaaaaaaaaaaaaaaaaaaa"; I did experiments with :addresses ["*"] without any luck. deliver only gets user and HOME directory form env variables provided by qmail, so it's unaware of the target email address. 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. So, it seems they are compatible. if i click OK on Thunderbird, when using my Verisign-signed certificates, everything works and i do got TLS logs: Feb 18 12:23:36 correio dovecot: imap-login: Login: user=<user(a)domain.com.br>, method=PLAIN, rip=201.86.xx.xx, lip=192.168.1.2, TLS, TLSv1 with cipher DHE-RSA-AES256-SHA (256/256 bits) Feb 18 12:31:43 correio dovecot: imap-login: Login: user=<user(a)domain.com.br>, method=PLAIN, rip=201.86.xx.xx, lip=192.168.1.2, TLS, TLSv1 with cipher DHE-RSA-AES256-SHA (256/256 bits) what am i doing wrong ?? or using a signed-certificate for WEB usage is not possible on dovecot ? -- 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

[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] tls not working on ubuntu
by zhong ming wu 18 Feb '10

18 Feb '10

Hello List, I'm new to dovecot. I have sucessfully configured dovecot with just virtual users on a centos linux box to my satisfaction; I can connect with TLS with disable_plaintext_auth = yes. This dovecot is also version > 1. Can't post exact version right now but it's what comes with Centos 5.4. On a Ubuntu 9.10 box here, I cannot connect with TLS (port 110) but I can connect with plain SSL (port 995). The config files between centos and ubuntu boxes are the same except for minor details. The following is the log entry Feb 17 21:38:18 ubuntu dovecot: pop3-login: Disconnected (no auth attempts): rip=192.168.0.101, lip=192.168.0.108 The output below is from a binary compiled from source. I have also tested with 1.1.11 (that I get from apt-get install) with the same config file. I have tested ubuntu with both Thunderbird 3 and thunderbird 2. I have also searched google as well as dovecot website.

[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
by Wayne Thursby 15 Feb '10

> 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. I've gained much from just lurking in this list, just trying to contribute where I can. -- Wayne Thursby System Administrator Physicians Group, LLC

[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?

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

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 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]-- \ This morning at breakfast, I noticed that Kellogg's have put a helpline number on their cornflake packets. When you need a helpline for breakfast cereals, it's time to start thinking about tearing down civilisation and giving the ants a go. --Chris King -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkt2wGAACgkQ3kWu7Tfl6ZR3qQCgv7+smY1v1YY3OAK+A2lH/adr JtIAoIU+yd9zecP+iKoSxOAyaZJLnRfR =KnFa -----END PGP SIGNATURE-----
