[Dovecot] cgroup support
by Andreas Pelme 01 Feb '11

01 Feb '11

Hi, I am setting up a system that enforces cgroup restrictions when a user logs in via SSH, and for all the services that are run by a particular user. I am also running dovecot to give users IMAP/POP access to their mailboxes. However, to be part of a cgroup, PIDs must be explicitly added to the cgroup tasks file. So for now, all my processes are run with resource restrictions, except for Dovecot processes. It would be really cool if dovecots child/worker processes could be added the a cgroup in addition to the usual setuid/chroot protections that already exists. Adding a process to a cgroup is a matter of writing the PID to the correct cgroup tasks file. If this were implemented as an extra field in userdb, it could be very powerful, and allow for all kinds of resource management/accounting of dovecot processes. This would obviously not be cross-platform, since cgroups are a feature of the Linux kernel. Would that be a problem? Is support for cgroups something that could be considered for dovecot at all? Are there other ways to put dovecot processes in cgroups? I do not really have a patch or a plan for how everything would work out in detail. If this would be useful for dovecot, I would be happy to start hacking on a patch. Cheers Andreas

[Dovecot] Permissions issues after dovecot reload
by Matt Rude 01 Feb '11

01 Feb '11

Hello, Today while looking at a different issue (one user couldn't retrieve mail; DNS issue) I set 'mail_debug=yes' then ran `dovecot reload` on our mail server. After running the reload, dovecot started complaning about permission issues with the dict file, and preceded to try to kill it's self. The self reload didn't seem to work, and since this is a production system, I was forced to restart the dovecot service. After the restart of the service, everything seemed to go back to normal. Dovecot is currently working as expected, no other permission errors in the logs. Dovecot Version: 2.0.9 (3582271a897e) running on Fedora 14 running with a mySQL setup including dict tables (quota, expire). The virtual user's mail has a local user and group id of 1000.

[Dovecot] disable_plaintext_auth = no ignored by dovecot in Ubuntu 10.04
by David Mattox 31 Jan '11

31 Jan '11

Help!! I have been trying to get Dovecot configured to allow plaintext auth with no success. After some testing with the mail system I discovered the >dovecot -a commant to dump the config file values from the program. Gee, changing the value of disable_plaintext_auth had no effect on what the program reported this value to be! To eliminate possible errors caused by other config file entries I finally restored the /etc/dovecot/dovecot.conf file that was created by installing the package. I then changed the one line to uncomment disable_plaintext_auth and set it equal to no. restart the box and execute dovecot -a The value is still set to the default value of yes... Help! What is happening and how to I get this system to allow plain text auth without TLS? I did also try setting different ports for imap, imaps, pop3, pop3s inside the seperate protocol blocks with no effect. Below you will find a partial of the config file. Below that you will find the output of >dovecot -a and >dovecot -n Thank you in advance for any help with this problem.

[Dovecot] Particular user post-login hang
by Henry C. 31 Jan '11

31 Jan '11

Greets, I'm using dovecot 2.0.9 (also tried rolling back to 2.0.8 which does the same - the output below is from 2.0.8), and this problem is imap specific. The following is a recurring problem with a specific user - as far as we can tell, other users are working just fine (there are thousands); but I bet there are others. In a nutshell: User authenticates OK, then the imap process hangs. It's almost as if something in the user's inbox is causing the problem, since if I clear all emails (and cache), then things work fine. The user will then receive emails OK for some random period (maybe a few days) and be able to read/write OK via imap, and the problem will re-occur.

[Dovecot] dovecot can't see mail that is there
by Joachim Ferreira 31 Jan '11

31 Jan '11

Hi list, I've yet to figure out what's the issue with my installation, why I can't see the mails that are definitely there. I've updated with last package: dovecot-2.0.9-1.fc14.x86_64.rpm and performed the following test: 1) send a simple 2 lines test mail from "root" to user "testdvct" with alpine 2) login under "testdvct" + run alpine + list (only list, not read) the mail: +------------------------------ Alpine Output --------------------------------------+ | ALPINE 2.02(1266) MESSAGE INDEX Folder: INBOX Message 1 of 1 NEW | | | | + N 1 17:43 root (881) | +--------------------------------------------------------------------------- --------+ so it tells me I've got one mail from root 3) I issue the command: "strace -o strace-dovecot.txt -p 2218" where 2218 is the /usr/sbin/dovecot PID 4) telnet into pop3: # telnet localhost pop3 Trying 127.0.0.1...

[Dovecot] Duplicate messages when moving message to inbox
by Ron Garret 31 Jan '11

31 Jan '11

Hello, I am encountering a strange problem but I'm not sure if it's a dovecot problem or a Mac Mail problem. The symptom is that if I move a message from a folder into my inbox the message ends up showing up as a duplicate in Mac Mail. On the server it's still just one message. This ONLY happens when I move a message IN to the inbox. It does not happen when I move a message out of my inbox into a folder, or when I move a message between folders. I can force a sync on Mac Mail and the duplicate is still there. If however I quit Mac Mail and start it up again, the duplicate disappears. I can move one of the duplicated messages out of my inbox into a folder and then back into my inbox repeatedly and end up with (apparently) an arbitrary number of copies of the same message. On the server, though, there is still only one file. Surely I'm not the first person to have encountered this behavior? Does anyone happen to know if this is a dovecot bug or a Mac Mail bug (or, hopefully, a configuration problem)? Thanks, rg

It's a theoretical problem mostly, especially in your case. It's mainly visible when doing stress testing with large maildirs. I doubt in regular use it matters. Courier doesn't try to prevent it in any way and it seems to have worked mostly ok. > Or is the UID supposed to change when the flags change? No.

[Dovecot] dovecot: pop3-login: Disconnected (tried to use disabled plaintext auth): method=PLAIN
by John Espiro 30 Jan '11

First, my problem. Settings are below that... Everything works fine - I can login to webmail (users are tied to LDAP). I can send and receive email via my Thunderbird Client. However in my mail.err log I see lots of messages that say: dovecot: pop3-login: Disconnected (tried to use disabled plaintext auth): method=PLAIN 1.) What does that mean, and how can I solve it? 2.) With regards to pop3s I am not altogether sure that I am using the right config in my dovecot.conf file (also below). Can someone let me know?

[Dovecot] inform users's about new spam
by ckubu 30 Jan '11

30 Jan '11

Hallo evryone! Mailsetup: postfix+dovecot2 with postgres database backend - about 2,000 virtual mailboxes, growing.. New possible spam will be sorted into a users directory named "spam", emails older than 30 day's in that folder will be deleted by using expunge. I would like to inform my users evry two day's (or something like that) about new emails in the spam folder. Can you give me a hint how to handle that ? Are there helpful tools , or have i to wrote my own script, walking through the folders, checking for new emails since last check and finally inform the user if needed. Best wishes Christoph

[Dovecot] Copying sieve scripts
by Christoph Pleger 30 Jan '11

30 Jan '11

Hello, I am using squirrelmail with avelsieve to edit my filter rules. The filter rules are like this: 1. If the message contains a virus, delete the mail and notify me by email. 2. If the message is spam, deliver it to my spam folder. 3. If the message is from the dovecot mailing list, deliver it to my dovecot folder Yesterday, I created a new user and wanted to let him have rules 1 and 2 like above, only with another destination for email notification. So, I copied my sieve script into the sieve directory of the new user, deleted rule 3, changed the destination for email notification and then called sievec to compile the rule set. But this did not work like expected: Using squirrelmail, I saw that the new user had only rules 1 and 2, but the destination in rule 1 still contains my email address. My own account still has three rules. So, this simple way of copying sieve scripts does not work. Is there another way to copy sieve rules from one user to another? Regards Christoph

[Dovecot] sql : uid, gid, home ignored ?
by Eric Diaz Fernandez 30 Jan '11

30 Jan '11

Hello, I'm trying to setup a dovecot imap server. version is 2.0.9 I've setup a mysql database using: user_query = \ SELECT home, uid, gid, home as userdb_home, uid as userdb_uid, gid as userdb_gid, \ FROM user WHERE username = '%n' AND domain = '%d' AND active = 'Y' password_query = \ SELECT username AS user, password, home as userdb_home, uid as userdb_uid, gid as userdb_gid, home, uid, gid \ FROM user WHERE username = '%n' AND domain = '%d' AND active ='Y' (I get the information with and without the userdb_ prefix since I was not sure what was needed) When I login, I see the password_query in the debug log and it says: client out: OK 1 user=theuser home=/home/theuser uid=1000 gid=1000 master in: REQUEST 547880961 10068 1 e6...(hexadecimal stuff) master out: USER 547880961 theuser But in the mail.err log i see: dovecot: imap(theuser): Error: user theuser: Couldn't drop privileges: User is missing UID (see mail_uid setting) dovecot: imap(theuser): Error: Internal error occurred. Refer to server log for more information. The same two lines are also displayed in mail.info and mail.log Further testing (setting mail_uid & mail_gid to a nobody) shown that the home setting was ignored too. The sql example says that uid and gid are supposed to be an override of the mail_uid and mail_gid settings. Any idea of why the columns are ignored ? Thanks in advance, Eric

[Dovecot] Cooperating with dovecot in its Maildir
by Rob Browning 29 Jan '11

29 Jan '11

Is it possible to cooperate with dovecot within its Maildir, and if so, what's required? In this particular case, we're thinking of trying to allow notmuch to operate directly on the dovecot Maildir, and at the moment, the only modifications notmuch makes are to change maildir flags. Would locking dovecot-uidlist.lock be sufficient, perhaps via liblockfile? Also, is there some reliable way to detect a dovecot Maildir? For example, are any of the dovecot-* files guaranteed to exist all the time? Thanks -- Rob Browning rlb @defaultvalue.org and @debian.org GPG as of 2002-11-03 14DD 432F AE39 534D B592 F9A0 25C8 D377 8C7E 73A4

[Dovecot] How do I do this with mdbox?
by Odhiambo Washington 29 Jan '11

29 Jan '11

In my life with Maildir, mails were stored as single files, each mail per file. It was pretty easy to resend an e-mail from a Maildir folder to another address, by causing the mail to be re-injected into my MTA (Exim) queue for processing: I'd use a very simple shell script to achieve the above: #!/bin/sh email=$(find $*) { for x in ${email}; do sendmail president(a)egypt.gov < ${x}; done } Now, with mdbox container/storage, it beats me how to achieve the same. -- Best regards, Odhiambo WASHINGTON, Nairobi,KE +254733744121/+254722743223 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Damn!!

[Dovecot] Sharing user folders doesn't work when users have periods in names.
by ian+dovecot＠comtek.co.uk 28 Jan '11

28 Jan '11

I am using period as an IMAP separator with Maildir directories and I cannot share folders where the user has a period in their name. Suppose I log in as 'some.user' and do: SETACL INBOX mailtest(a)example.co.uk +lrwstipekxacd /var/mail/virtual/users/some.user/Maildir/dovecot-acl is created, with appropriate contents and shared-mailboxes.db gains an entry for 'shared/shared-boxes/user/mailtest@example.co.uk/some.user@example.co.uk'. mailtest is simply unable to see a new folder. As mailtest 'a LIST "" "Users.*" ' is empty. If I do ' a MYRIGHTS Users.some.user.INBOX ' I get 'NO [NONEXISTENT] Mailbox doesn't exist: Users.some.user.INBOX' and, oddly, a new maildir appears: '* LIST (\Noselect \HasChildren) "." "Users.some" ' -- it also creates an empty folder structure with a single file /var/mail/virtual/users/some/Maildir/dovecot-acl-list too! Is there a workaround that does not involve rebuilding every user's Maildir with backslash as a separator? Thanks, Ian

Hi, i'm new on sieve, but want to use ist with sogo. The Problem is, that when i set a redirect or vacation rule like: redirect "email(a)example.com"; (real Adress is different) the sieve says the mail would be forwarded, but no mail is sent. (No Action in /var/log/maillog) And because there is no Error-Message it's difficult to search for...

[Dovecot] Telnet access creates new maildir folders
by Seasoul 28 Jan '11

28 Jan '11

Hi, I am running Dovecot Version 1.0.15on a Debian server, with postfix and postfixadmin. My mailbox base is /var/mail/vmail When I send an email to a user1(a)domain.com for the first time, the user "mail" creates a set of dovecot folders under /var/mail/vmail/ user1(a)domain.com/ and my new emails are found in /var/mail/vmail/ user1(a)domain.com/new When I test my server using telnet (telnet domain.com 110), I can log in fine as a user1, but when I type "LIST", it tells me there are no emails. And I realize a new set of dovecot folders were created under /var/mail/vmail/user1/ ! The folders are created by the user "user1". Obviously the folder "new" under that is empty, since my emails received are in /var/mail/vmail/user1(a)domain.com/new and not /var/mail/vmail/user1/new . Therefore, connecting with an email client via POP also shows an empty inbox. I am lost as to what to do to fix this, and how to let the server know that pop access should be looking into /var/mail/vmail/user1(a)domain.com/ instead of /var/mail/vmail/user1/ . Hopefully someone on this list will be able to save me from my misery :) Cheers Sea

[Dovecot] Best way to calculate concurrent users?
by Henrique Fernandes 28 Jan '11

28 Jan '11

Well, i am having some problens to figure out how many concurrent users into the server! In my envoriment now, most people are using the webmail interface, and it just conect and disconct pretty quickly so i can not get it with "doveadm who" doveadm who only gets the ones that are connect with clients. O use ipvs to balance betwaeen 2 servers does anyone have an ideia ? With ipvs i get this results: IP Virtual Server version 1.2.1 (size=4096) Prot LocalAddress:Port Scheduler Flags -> RemoteAddress:Port Forward Weight ActiveConn InActConn TCP XXX.XX.X.XX:143 lblcr -> 10.0.2.10:143 Masq 1 16 228 -> 10.0.2.11:143 Masq 1 16 184 There is others ports and stuff. Does any one have an ideia how to get this number ? []'sf.rique

[Dovecot] Storing Dovecot index files on sql
by list＠airstreamcomm.net 28 Jan '11

28 Jan '11

We have been communicating with the mailling list on another thread regarding dotlocking on the dovcot-uidlist over an NFS share, and I was hoping to get some ideas on whether or not a sql database would be a suitable location for storing the dovecot index files. Our though process so far has been that storing the index files on NFS with the maildir has not worked very effectively when we are using multiple Dovecot servers (even using sticky IPs in our load balancer), and using local storage is not possible with a cluster of machines, so we got to thinking about what type of storage platform would be suitable for these index files that would provide native locking of the data while multiple servers accessed and wrote to it. Our question to the community is whether sql storage for index files has ever been considered, what issues would this introduce, and if it's even feasible? Thanks everyone! Michael

[Dovecot] Differenft INBOX for IMAP/POP with checkpassword passdb
by Peter Mogensen 27 Jan '11

27 Jan '11

Hi, I'm trying to do a setup where IMAP and POP users see different INBOX' Like described on the virtual folder wiki page: http://wiki.dovecot.org/Plugins/Virtual However, for now, I'm stuck with the checkpassword passdb and prefetch userdb So I can't parameterize the result on %s like the example with MySQL does. So I thought of having to different checkpassword scripts: passdb checkpassword { args = /usr/bin/checkpassword-%s } However, Dovecot (1.2.15) doesn't seem to expand %s even though the Wiki says it should be available everywhere: http://wiki.dovecot.org/Variables Is this a bug, or am I missing something. /Peter

[Dovecot] Best Cluster Storage
by Jonathan Tripathy 27 Jan '11

27 Jan '11

Hi Everyone, I wish to create a Postfix/Dovecot active-active cluster (each node will run Postfix *and* Dovecot), which will obviously have to use central storage. I'm looking for ideas to see what's the best out there. All of this will be running on multiple Xen hosts, however I don't think that matters as long as I make sure that the cluster nodes are on different physical boxes. Here are my ideas so far for the central storage: 1) NFS Server using DRBD+LinuxHA. Export the same NFS share to each mail server. Which this seems easy, how well does Dovecot work with NFS? I've read the wiki page, and it doesn't sound promising. But it may be outdated.. 2) Export block storage using iSCSI from targets which have GFS2 on DRBD+LinuxHA. This is tricky to get working well, and it's only a theory. 3) GlusterFS. Easy to set up, but apparently very slow to run. So what's everybody using? I know that Postfix runs well on NFS (according to their docs). I intend to use Maildir Thanks

[Dovecot] Questiosn about dbox
by Javier de Miguel Rodríguez 26 Jan '11

26 Jan '11

Hello I have read carefully about dbox (/http://wiki2.dovecot.org/MailboxFormat/dbox/) and I have some questions: - One of the main advantages (speed wise) of dbox over maildir is that index files are the only storage for message flags and keywords. What happens when we want to recover some messages from backup? With maildir we can rebuild message indexes, but I am not sure about dbox. Should we also restore "old indexes" and merge with the "new indexes" in order to restore the deleted messages? - The previous question applies to sdbox and mdbox. In the case of mdbox, we can configure rotation of files using /mdbox_rotate_size/ . We would like to rotate daily, not based in size (our users ask us for yesterday's backup). How can we accomplish this? We have now 17.000.000 messages in our maildir, almost 1.5 TB (zlib compresssion enabled). Our backup time with bacula is rather bad: 24 hours for a full backup, most of the time the backup is busy fstat'ing all those little messages. We think that mdbox can help us in this. Does anybody has good experiences migrating from maildir->mdox in "large" enviroments? What about mdox performance & reliability? Thank you for your support Javier

[Dovecot] shared namespace subscription
by adrian.stoica＠dacris.net 25 Jan '11

25 Jan '11

I test dovecot 2.0.9 and i use a shared namespace. I use this to see inbox for user2 in shared namespace for user1. When user2 unsubscribe for inbox , the shared inbox disapear too from shared namespace in user1 list. This is normal ? I believe that whatever subscription has user2 , if the director is shared , only the indexes will be copyied from the original place, not along with the subscription.

[Dovecot] custom maildir location mapping
by Vlad Mazek 25 Jan '11

25 Jan '11

Greetings, I'm migrating from a sendmail/dovecot setup with system users to a postfix/dovecot maildir setup with virtual users. To simplify the mess we've gotten into by having users that can't remember their username, we've switched to email address being the username. In order to allow for a smooth migration, I need to allow users to be able to login with their email address as well as their (old) username for about a month or so. I have all the usernames, email addresses and passwords stored in SQL and I'm generating the userdb and passworddb manually. Is there any way to create a userdb and passworddb so that users can login with either username or email address and have dovecot locate their maildir without an issue? For example, I'd like to be able to login as either vlad or vlad(a)vladville.com and have dovecot locate my maildir:/var/spool/mail/%d/%n; I'd really appreciate any thoughts, ideas and examples anyone is willing to share. I'm really looking to avoid a shotgun approach ("On Feb 1, your new username is your email address"). Here are some notes on the currently functioning setup: I'm running dovecot 1.0.7 on CentOS 5.5 x64 with Postfix 2.3.3 mail_location = maildir:/var/spool/mail/%d/%n userdb static { args = uid=virtual gid=virtual home=/var/mail/%d/%u } passdb passwd-file { args = /etc/dovecot/passwd } user@domain.com:{HMAC-MD5}1b05f379...

[Dovecot] PAM problem with virtual domain/user ownership
by Mauricio Tavares 25 Jan '11

25 Jan '11

I am running dovecot 1.2.9 (ubuntu package, not from source) and wanted to use pam to authenticate my mail users who have no local accounts. I've done that before in an earlier release of dovecot and ubuntu, so I would not need to do set dovecot to ask LDAP directly. So, I have in dovecot.conf: # Authentication processes mechanisms = plain login passdb pam { args = "*" } userdb static { args = allow_all_users uid=virtual gid=virtual home=/var/spool/vmail/domain.com/%n } i.e. /var/spool/vmail/domain.com/ is owned by virtual:virtual, drwxr-x--- 4 virtual virtual 4.0K 2011-01-23 11:45 domain.com and that is how I would hope dovecot would be trying to login as. When I tried to login as user raub, the log file seems to tell me that it is trying to create /var/spool/vmail/domain.com/raub/cur as raub:users, not as virtual:virtual Jan 22 06:35:02 mail dovecot: imap-login: Login: user=<raub>, method=PLAIN, rip=216.155.101.90, lip=216.155.101.94, TLS Jan 22 06:35:02 mail dovecot: IMAP(raub): mkdir(/var/spool/vmail/domain.com/raub/cur) failed: Permission denied (euid=5016(raub) egid=100(users) missing +w perm: /var/spool/vmail/domain.com) What am I missing here?

[Dovecot] SSD drives are really fast running Dovecot
by Marc Perkel 24 Jan '11

24 Jan '11

I just replaced my drives for Dovecot using Maildir format with a pair of Solid State Drives (SSD) in a raid 0 configuration. It's really really fast. Kind of expensive but it's like getting 20x the speed for 20x the price. I think the big gain is in the 0 seek time. Here's what I bought. Crucial RealSSD C300 CTFDDAC256MAG-1G1 2.5" 256GB SATA III MLC Internal Solid State Drive (SSD) <http://www.newegg.com/Product/Product.aspx?Item=N82E16820148349> * 2.5" * 256GB * SATA III * *Sequential Access - Read:* 355MB/sec (SATA 6Gb/s) 265MB/sec (SATA 3Gb/s) * *Sequential Access - Write:* 215MB/sec (SATA 6Gb/s) 215MB/sec (SATA 3Gb/s) * *Power Consumption (Active):* 2.1W READ, 4.3W WRITE * *Power Consumption (Idle):* 0.094W Running it on an Asus motherboard that supports SATA III - 6 core AMD CPU and 16 gigs of ram. Might be slightly off topic but this server screams!

[Dovecot] How to enable COPY and APPEND commands separately
by Alex Cherniak 24 Jan '11

24 Jan '11

I'd like to allow a user to move messages between his folders on Dovecot IMAP account, but prevent move/copy from different accounts (Exchange in particular). Outlook uses "xx UID COPY 1 folder" and then "xx UID STORE 1 +FLAGS (\Deleted \Seen)" for internal moves and "xx APPEND folder" for external ones. I tried to achieve this with ACL, but i (insert) seems to control both. Do I miss something? Should I look somewhere else? Please help.

[Dovecot] Dovecot Update on Ubuntu from 1.0.10 to 1.2 doesn't work
by franc walter 24 Jan '11

24 Jan '11

Hello, i have an ubuntu 8.04 LTS Virtual Server with Dovecot 1.0.10 and postfix. Now i tried to update Dovecot because i need Quota, which is not possible in 1.0 but in 1.2 So i added the packages to my /etc/apt/sources.list: deb http://codex.xiaoka.com/apt hardy main restricted deb http://archive.ubuntu.com/ubuntu hardy-backports main universe multiverse restricted and updated dovecot with aptitude. After this i killed the proc master and restarted postfix and dovecot but now dovecot is running but doesn't get any more mails from postfix. I had to downgrade back to 1.0.10 and after this all is working again. I immediately looked into the mail.log, but i didn't see any clear errors. I uploaded the mail.log here, maybe someone could give me a hint, what it could be: http://7fw.de/tmp/2011-01-24-23-38-mail.log I started the update at 2011-01-23 at 23:00 and downgraded back at 2011-01-24 at 00:26. In the error.log i only have errors about inotify, which is not available on the ubuntu server (old kernel version, cannot be updated by provider). I set in dovecot.conf: mail_debug=yes auth_debug=yes auth_debug_passwords=yes but this didn't help me. Thank you, Kind regards, franc walter

[Dovecot] Using dsync+imapc for migration from other IMAP servers to Dovecot
by Timo Sirainen 24 Jan '11

24 Jan '11

Dovecot v2.1 hg (http://hg.dovecot.org/dovecot-2.1) now supports doing e.g.: dsync -o plugin/imapc_user=remote.user(a)example.com -o plugin/pass=remote-password mirror imapc:imap.example.com dsync will preserve message UIDs and UIDVALIDITY/UIDNEXT values for mailboxes, just like with all other storage backends. A couple of bad things: 1) It currently fetches one message at a time from server. Very slow.. Will be fixed some day. 2) You can't do incremental sync, because dsync relies on message GUIDs, which aren't available in IMAP protocol. This could be fixed some day. Also a support for Dovecot extension could be added some day to make this work for Dovecot as remote IMAP server.

[Dovecot] Does dsync handle client-side deletions?
by Patrick Schoenfeld 21 Jan '11

21 Jan '11

Hi there, I'm currently evaluating the idea of a multi-master setup where each node shall hold a full copy of the mailboxes. Basically the idea is to use NFS and dsync to keep those copies in sync. So I did some tests with dsync and ran into a problem. Consider the following scenario: 1) Location1 and Location2 are in sync 2) A mail gets deleted on Location1 (via IMAP) 3) dsync mirror run to sync the two locations Expected behaviour: dsync notices that the mail was deleted on Location1 and also deletes it on Location2 to get the locations in sync. What I experience, however, is: dsync notices that the mail is missing on Location2 and copies it from Location1 to get the locations in sync. (At least) In debug mode it will spit a warning: dsync(test2): Info: INBOX: highest_modseq changed: 8 != 11 dsync(test2): Info: INBOX: Couldn't keep all uids dsync(test2): Info: INBOX: Ignored 1 modseq changes dsync(test2): Warning: Mailbox changes caused a desync. You may want to run dsync again. Now the question is: Doesn't dsync handle deletions or is there something I missed? Dovecot version is 2.0.9. Thanks in advance and best Regards, Patrick

[Dovecot] utility to update indexes ?
by Jan-Frode Myklebust 21 Jan '11

21 Jan '11

We have both dovecot and a webmail application that are both modifying our users maildirs, so dovecot indexes can be out of sync when the webmail has been messing with the maildirs. We also have a webservice that report how many unread messages a user has in his inbox, which is simply counting files in the maildirs (plus caching the result, and present old values if the directory timestamps hasn´t changed). I think this checking of unread messages webservice would be much nicer on the filesystem if it instead used the dovecot indexes, so I created a small utility based on utils/idxview.c that do that: http://blag.tanso.net/code/unread.c But this woun´t work if the maildir has been modified outside of dovecot (i.e. webmail usage). Are there any simple interface I can use in this short snippet for noticing that the index is out of sync, and update it ? -jf

[Dovecot] LMTP & home, chroot, mail userdb fields.
by Lev Serebryakov 21 Jan '11

21 Jan '11

Hello, Dovecot. I'm using postfix + dovecot with pure virtual users. postfix uses standard virtual transport, and dovecot fetches such fields from userdb: chroot: "/usr/home/hosted/v-mail/%d/%n" home: "/" mail: "maildir:." Everything works Ok -- dovecot founds users' mail. Now, after upgrade to dovecot2, I want to use it LMTP server as virtual_transport in postifx. I've changed virtual_transport setting to "lmtp:unix:/var/run/dovecot/lmtp". dovecot's LMTP can not deliver messages, because it seems that it uses userdb fields in some OTHER way.

[Dovecot] Feature request - statistics for the COMPRESS imap protocol
by Ed W 21 Jan '11

21 Jan '11

Unless I have failed to read the manual for the second time in two days (?), it doesn't seem to be possible to get COMPRESS statistics at logout time from the IMAP protocol? Assuming not, then can I make a feature request that this might become available in some future version (pretty please?) Can I also just check that the meaning (as of today) of the "imap logout" statistics "%i/%o", presumably they refer to bytes over the wire, ie they are the compressed data sizes? Thanks - Dovecot 2 adds a fantastic bag of new features! Ed W

[Dovecot] Fwd: Re: Dotlock dovecot-uidlist errors / NFS / High Load
by list＠airstreamcomm.net 21 Jan '11

21 Jan '11

Stan, Thanks for the reply. In our case we have actually already done most of the work you suggested to no avail. We had rebuilt two new ntp servers that sync against two stratum 1 sources, and all our nfs clients, regardless of using dovecot, sync to those two machines. You bring up the difference between bare metal and hypervisor, and we are running these machines on vmware 4.0. All the vmware knowledge base articles tend to push us towards ntp, and since we are using centos 5.5 there are no kernel modifications that need to be made regarding timing from what we can find. I will give the ntpdate option a try and see what happens. I was also hoping to understand why the uidlist file is the only file that uses dotlock, or if there was plans to give it the option to use other locking mechanisms in the future. Thanks again!

In a clustered server environment, _always_ run a local physical box/router ntpd server (preferably two) that queries a set of external sources, and services your internal machine queries. With RTTs all on your LAN, and using the same internal time sources for every query, this clock drift issue should be eliminated. Obviously, when you first set this up, stop ntpd and run ntpdate to get an initial time sync for each cluster host. If after setting this up, and we're dealing with bare metal cluster member servers, then I'd guess you've got a failed/defective clock chip on one host. If this is Linux, you can work around that by changing the local time source. There are something like 5 options. Google for "Linux time" or similar. Or, simply replace the hardware--RTC chip, mobo, etc. If any of these cluster members are virtual machines, regardless of hypervisor, I'd recommend disabling using ntpd, and cron'ing ntpdate to run once every 5 minutes, or once a a minute, whatever it takes to get the times to remain synced, against your local ntpd server mentioned above. I got to the point with VMWare ESX that I could make any Linux distro VM of 2.4 or 2.6 stay within one minute a month before needing a manual ntdate against our local time source. The time required to get to that point is a total waste. Cron'ing ntpdate as I mentioned is the quick, reliable way to solve this issue, if you're using VMs. -- Stan

[Dovecot] Populating mailbox dir

Let's say you created a (virtual) mail user but have not created the user mail directory. When you first try to access it, the mail directory is created and populated: ls -a /var/spool/vmail/domain.com/raub/ . dovecot.index.log dovecot-uidvalidity.4d375a39 tmp .. dovecot-uidlist new .Trash cur dovecot-uidvalidity subscriptions Who populates/creates the initial files and folders in the user mailbox? Dovecot? The mail client accessing it through imap? Elvis? If dovecot, is there a way to customize it a bit, so a few extra folders will also be thrown there?

I have errors in log: mail dovecot: auth: Error: LDAP: binding failed (dn cn=administrator,ou=users,dc=my,dc=domain): Invalid credentials, 80090308: LdapErr: DSID-0C090334, comment: AcceptSecurityContext error, data 525, vece This is my dovecot.conf file: protocols = imap disable_plaintext_auth = no listen = * ssl = no auth_mechanisms = plain base_dir = /var/run/dovecot/ mail_location = mbox:/home/vmail/%n/ passdb { driver = ldap args =/etc/dovecot/dovecot-ldap.conf } userdb { driver = ldap args = /etc/dovecot/dovecot-ldap.conf } And this is my dovecot-ldap.conf: hosts = 192.168.0.19 dn = cn=administrator,ou=users,dc=my,dc=domain dnpass = password base = ou=myuser,dc=my,dc=domain scope = subtree ldap_version = 3 auth_bind = yes auth_bind_userdn = ou=myuser,dc=my,dc=domain user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid user_filter = (&(objectClass=posixAccount)(uid=%u)) pass_attrs = uid=user,userPassword=password pass_filter = (&(objectClass=posixAccount)(uid=%u)) Should I have any file in /etc/pam.d ?

[Dovecot] domain stripping
by PA 20 Jan '11

20 Jan '11

Hi, using dovecot 2.0 and I'm using a couple of user DBs, sql/prefetch and pam. Currently if the user logins with username@domain it authenticates off the sql DB and works fine. If the user logins with username with no @domain it fails on the sql lookup and succeeds on the pam user DB. However I was wondering if I can have another sql DB lookup that says when the user logins and fails against the first two user DBs, sql/pam db, to try this last sql user DB and appends a default domain to it, because the sql DB lists username with the domain. Currently I have all users login in with no realm on the older mail server and I wanted to migrate these users to dovecot 2.x with minimal impact and wanted to have the ability for these virtual users to login with and without a realm. Thanks paul.

[Dovecot] Problems with Upgrade from Courier
by Aaron Pettitt 20 Jan '11

20 Jan '11

I inherited a server from a previous employee. The server crashed so it was time to move everything over to another server. We have a web mail site and I installed everything running dovecot, postfix and roundcube. After I installed it, everything worked great when I created a new user. The new user could send and receive emails with no issues. I then copied the home directory over from the other server and ran the courier-dovecot migration script. It created the subscription files and the dovecot-uidlist files in each user (about 1000 total users). When I login as one of the existing users, it says that there is no mail in the mailbox. However, if I look at the user's cur and new folders, there is mail in those folders. If I send a new mail to the user, it does not show up in their inbox. If I look in their new folder, the new mail that I sent was delivered to that folder but it does not show up in their inbox. I've tried going to dovecot directly through telnet with the same results. I've been stuck for 2 days now so any help is greatly appreciated. Below is my dovecot.conf with all the comments removed. Thanks all! protocols = imap imaps disable_plaintext_auth = no log_path = '/var/log/dovecot/error.log' info_log_path = '/var/log/dovecot/info.log' log_timestamp = "%m/%d/%Y %H:%M:%S " #mail_location = maildir:~/ mail_location = maildir:/home/vmail/%d/%n/ mail_privileged_group = mail mail_debug = yes protocol imap { } protocol pop3 { } protocol managesieve { sieve_storage=~/sieve } protocol lda { log_path = /home/vmail/dovecot-deliver.log auth_socket_path = /var/run/dovecot/auth-master postmaster_address = postmaster(a)mybridemal.com mail_plugins = cmusieve global_script_path = /home/vmail/globalsieverc } auth_verbose = yes auth_debug = no auth_debug_passwords = no auth default { passdb sql { args = /etc/dovecot/dovecot-sql.conf } args = uid=5000 gid=5000 home=/home/vmail/%d/%n allow_all_users=yes } user = root path = /var/run/dovecot/auth-master mode = 0600 user = vmail #group = } client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } } }

[Dovecot] Bug found, assertion failed
by Tobias Daucher 20 Jan '11

20 Jan '11

Hi there, We're running dovecot 2.06, with mdbox. Following message was in our syslog: Jan 20 09:26:48 servername dovecot: [ID 583609 mail.crit] imap(user): Panic: file istream-limit.c: line 79: assertion failed: (v_offset <= lstream->v_size) The problem could be solved on client side, by just deleting the ImapMail-Folder in Thunderbird. Why? Thunderbird tried to move a message, that obviously wasn't there. Dovecot got killed and the message above was in the syslog. Connection was closed and Thunderbird told me the server is dead. Thunderbird tried this every few seconds, and there was no way to say thunderbird "stop try moving". So the only way was to delete thunderbirds mail cache. I think it would be very nice, if dovecot doesn't die, just because the client tries to move a message, which isn't there.

Go with a cluster filesystem such as OCFS or GFS2 and an inexpensive SAN > storage unit that supports mixed SSD and spinning storage such as the Nexsan > SATABoy with 2GB cache: http://www.nexsan.com/sataboy.php I can't speak for OCFS2, but after several years' experience with the filesystem I strongly recommend NOT using GFS/GFS2. Its locking model is incredibly slow (500 locks/second on a filesystem mounted with quotas enabled and noatime) and results in dire performance - plus there's a known crash vulnerability if files are repeatedly renamed in large directories (this bites us regularly...) GFS2 isn't an "enterprise" filesystem by any stretch of the imagination, despite what a number of enthusiastic salespeople might try to convince you of. We're lucky to keep the GFS servers up for more than a week at a time.

[Dovecot] Upgrading from 1.2 to 2.0
by list＠airstreamcomm.net 20 Jan '11

20 Jan '11

Greetings Dovecot mailing list! We are an ISP that recently migrated from Courier to Dovecot, and are looking at the next round of upgrades. Hoping that we could get pointed to some documentation or get a general list of best practices for an upgrade from 1.2.13 to 2.0.9. Our current environment consists of four Dovecot machines that share an NFS backend hosting POP and IMAP. Our biggest question is whether we can support a rolling upgrade from 1.2.13 to 2.0.9, or if it would need to be an all for one cut. Thanks in advance.

Cool, thank you Patrick! Must have missed that somehow. I put the setting in main.cf, "receive_override_options = no_address_mappings", right after 'content_filter' (running amavisd on a separate port) and it seems to have fixed the problem. -- Darek On Tue, Jan 18, 2011 at 7:05 PM, Patrick Westenberg <pw(a)wk-serv.de> wrote: > Darek M schrieb: > >> Anyone have an idea of what I should be looking at in a situation like >> this?

[Dovecot] Pigeonhole 2.2 build issue on arm
by Tom Talpey 19 Jan '11

19 Jan '11

When building Pigeonhole 2.2 for ARM, the following warnings are produced: uri-mailto.c: In function '_parse_hex_value': uri-mailto.c:139: warning: comparison is always false due to limited range of data type uri-mailto.c:145: warning: comparison is always false due to limited range of data type The problem is a test assuming that char is a signed type : static inline int _decode_hex_digit(char digit) { ... static bool _parse_hex_value(const char **in, char *out) { char value; // <<--- change to "int". if ( **in == '\0' || (value=_decode_hex_digit(**in)) < 0 ) return FALSE; *out = value << 4; (*in)++; if ( **in == '\0' || (value=_decode_hex_digit(**in)) < 0 ) return FALSE; This is untested, but I changed the "char value" to "int value" to correct the signed comparisons. There are no warnings when building for x86 in either case, btw. Also, the two tests for "**in == '\0'" seem to be unnecessary?

[Dovecot] Problem with seeing mail after Upgrade from Courier
by apettitt 19 Jan '11

19 Jan '11

I created a new server for a webmail system because the old server crashed. When I created the server, I installed Dovecot and the old server had Courier. On the new server, I'm doing virtual users where the old one created system users. I moved all the folders over for all the users on to the new server and ran the Courier-Dovecot migration script. The files were created successfully with no issues. The issue I'm having now is that Dovecot is not seeing any mail in the user's directory. If I create a new user, it can send and receive mail with no problems. If I send an email to an existing user, it gets delivered to the new folder but dovecot does not see anything in the new folder. There is also mail in the curr folder that dovecot does not see. I'm using Roundcube as a webmail client but I've also tried using Telnet with the same results. Any ideas? -- View this message in context: http://old.nabble.com/Problem-with-seeing-mail-after-Upgrade-from-Courier-t… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] Duplicate mail for forwards (dovecot+postfix+postfixadmin)
by Darek M 19 Jan '11

19 Jan '11

Dovecot 1.2.11, using postfixAdmin 2.3 to manage, basically using the postfixadmin schema and sql queries during install. - If I set a forward for an account to go to a remote email address, no dupes. - If I set a forward for an account to go to an email address on the same system, I get a dupe in the inbox of the second address. So if account1(a)domain.com has account2(a)domain.com as a forward, account2@ receives two copies of the same message, completely identical, same message IDs, same md5 sum. If I add account3@ into the mix, account3@ will also receive two copies of each message. I will also get a duplicate if I forward mail to account(a)anotherdomain.com, where anotherdomain.com is also hosted on the same system. account1(a)domain.com receives one copy. Here is the Dovecot log: Jan 18 17:24:40 deliver(account2(a)domain.com): Info: msgid=<4D361323.3040000(a)srvr.net>: saved mail to INBOX Jan 18 17:24:40 deliver(account1(a)domain.com): Info: msgid=<4D361323.3040000(a)srvr.net>: saved mail to INBOX Jan 18 17:24:40 deliver(account2(a)domain.com): Info: msgid=<4D361323.3040000(a)srvr.net>: saved mail to INBOX Postfix logs only show one delivery for each message, and since the headers aren't changed at all, I think the lda is at fault here. This is the entry for the account in the 'alias' table ======================== mysql> select * from alias where address='account1(a)domain.com'; +-----------------------+----------------------------------------+------------+---------------------+---------------------+--------+ | address | goto | domain | created | modified | active | +-----------------------+----------------------------------------+------------+---------------------+---------------------+--------+ | account1(a)domain.com | account1@domain.com,account2@domain.com | nyinet.com | 2010-11-28 18:07:40 | 2011-01-18 17:04:03 | 1 | Anyone have an idea of what I should be looking at in a situation like this? Does the 'goto' field look fine? -- Darek

by J4 18 Jan '11

Hi there, I changed postfix to pass email to spamassassin, and then deliver to dovecot LDA. It fails to deliver. The current entry in master.cf now reads: dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/deliver -d ${recipient} smtp inet n - - - - smtpd -o content_filter=spamassassin spamassassin unix - n n - - pipe user=nobody argv=/usr/bin/spamc -f -e /usr/sbin/sendmail -oi -f ${sender} ${recipient} This is the same as I had to afore I factored in spamassassin. The error message is this:- Jan 18 16:30:44 logout postfix/pipe[28952]: 56AE58230A: to=<test(a)test.info>, relay=dovecot, delay=0.01, delays=0/0/0/0.01, dsn=5.3.0, status=bounced (command line usage error. Command output: Fatal: Unknown argument: flags=DRhu Usage: deliver [-c <config file>] [-a <address>] [-d <username>] [-p <path>] [-f <envelope sender>] [-m <mailbox>] [-n] [-s] [-e] [-k] ) Does anyone know which options I should have added to dovecot deliver?

[Dovecot] v2.0.9 released
by Timo Sirainen 18 Jan '11

18 Jan '11

http://dovecot.org/releases/2.0/dovecot-2.0.9.tar.gz http://dovecot.org/releases/2.0/dovecot-2.0.9.tar.gz.sig I'm still lagging behind in my email, but I guess it's time to release v2.0.9 anyway. - Linux: Fixed a high system CPU usage / high context switch count performance problem - Maildir: Avoid unnecessarily reading dovecot-uidlist while opening mailbox. - Maildir: Fixed renaming child mailboxes when namespace had a prefix. - mdbox: Don't leave partially written messages to mdbox files when aborting saving. - Fixed master user logins when using userdb prefetch - lda: Fixed a crash when trying to send "out of quota" reply - lmtp: If delivering duplicate messages to same user's INBOX, create different GUIDs for them. This helps to avoid duplicate POP3 UIDLs when pop3_uidl_format=%g. - virtual storage: Fixed saving multiple mails in a transaction (e.g. copy multiple messages). - dsync: Saved messages' save-date was set to 1970-01-01.

[Dovecot] Question about indexes and maildir/sdbox/mdbox
by Javier de Miguel Rodríguez 18 Jan '11

18 Jan '11

Hello We are now running dovecot 2.0.9 with indexes in a ram disk and maildir storage in a test system. We have the following questions: - If there is a power outage / kernel crash, we will lose the content of ramdisk. We have tested that indexes are regenerated when a user logs in via imap, so e-mail access will be "slower" after a power outage / kernel crash, but everything should work as expected (TM). Are we missing something? - We are evaluating migrating from maildir to dbox. There are two alternatives: sdbox and mdbox. Reading about dbox in the wiki (http://wiki2.dovecot.org/MailboxFormat/dbox) we see that using a ram disk for indexes for mdbox is a really bad idea: /"Note that with dbox the Index files actually contain significant data which is held nowhere else. Index files for both *single-dbox* and *multi-dbox* contain message flags and keywords. For *multi-dbox*, the index file also contains the map_uids which link (via the "map index") to the actual message data. This data cannot be automatically recreated, so it is important that Index files are treated with the same care as message data files."/ So in mdbox we should not use a ramdisk for indexes. But what about sdbox? sdbox indexes work as maildir indexes? Are sdbox indexes bigger than maildir indexes? Thank you very much for your support Regards Javier

[Dovecot] Running two different versions of Dovecot (was: making folders unmovable)
by Dave 17 Jan '11

17 Jan '11

OK, so I decided to go ahead and just upgrade to the latest 1 series Dovecot and see if that solves my ACL/config issues I've been having. (I tried compiling 2.0.9, but it errored out and I assume that's because it's a pretty old machine/compiler.) Anyway, 1.2.16 compiled fine, and I installed it in another location from the currently running 1.1 series install. I have this new install running (IMAP) on a non-standard port while I test it out, and it starts fine and all seems well. However, I'm wondering, is it OK to run it and have it look at the same Maildir mailboxes as the currently running 1.1 series install? Does that have the potential to mess with indexes or change anything in a bad way? (FWIW, I tried it briefly, and after changing the port number in and restarting my mail client [Thunderbird], it had trouble pulling up the mailbox I was trying to access.) David

This is pretty much what I do with the mail domain I administer. I've set the INBOX with a modest quota, and a personal mail folder with a generous quota. I encourage users to keep their INBOX as a "working set", and archive the rest using any method they prefer. It forces users to process their Email (or at least their INBOX). and keeps packratting in check. Super-big INBOX quotas seem to encourage wasteful habits. I've helped some users clean out their mailboxes and was surpised at the amount of junk being kept for years and years. Apart from a few users moaning about their meager INBOX, this policy works out fairly well. Joseph Tam <jtam.home(a)gmail.com>

by Nikita Koshikov 17 Jan '11

17 Jan '11

Hello list, New version of dovecot segfaulting with expire plugin(sqlite db). Steps to reproduce: 1)DB file has permitions: -rw-r--r-- 1 mail mail 87040 Янв 17 10:04 /var/mail/expire.db 2)Dict dovecot config section: service dict { # If dict proxy is used, mail processes should have access to its socket. # For example: mode=0660, group=vmail and global mail_access_groups=vmail unix_listener dict { mode = 0600 user = mail } #user = mail } 3)Trying to add new record to database I get: Jan 17 10:03:12 dict: Error: sqlite: exec(INSERT INTO expires (expire_stamp,username,mailbox) VALUES ('1294852805','user(a)domain.com','Trash')) fail ed: attempt to write a readonly database (8) Jan 17 10:03:12 IMAP(user(a)domain.com 192.168.2.252): Error: read(/var/run/dovecot/dict) failed: Remote disconnected Jan 17 10:03:12 master: Error: service(dict): child 13957 killed with signal 11 (core not dumped) This crash has gone after service dict got enough permission to access db file(user mail in my case). Don't know how to get backtrace with dict service, but can reproduce crash any time.

[Dovecot] vpopmail disabled services fix
by Calvin 17 Jan '11

17 Jan '11

I noticed that disabling services using vpopmail was not being recognized by dovecot. Using "vmoduser -swip user(a)domain.com" should disable all services, but both pop and imap logins were still allowed. After a bit of digging in the code and confirming with a few debug lines, it appears that lines 38 and 52 of src/auth/passdb-vpopmail.c are the issue (dovecot 2.0.8). These two lines do a strcmp on request->service. It appears that request->service is in lower case, but the comparison values are in upper case. Either updating the values to lowercase or using strcasecmp should fix the issue.

[Dovecot] mail to admin when quota exceeded
by Karolis Žvaigždinas 16 Jan '11

16 Jan '11

We're using Dovecot v1.2.15 LDA/IMAP/POP3+MySQL with quota plugin, quota_rule per-user size, quota_exceed_message and quota_warning on storage=90%%.with script. Everything is working as expected. But I've been asked to configure it the way, that when a user gets message, which would make his maildir over quota limit, notification go not only to sender, but also to postmaster(a)domain.com. Browsed wiki, mailinglist archive - couldn't find anything on that. Is there a way to implement such feature? And what about possibility to send a message to user, notifying him about rejected email "from: xxx(a)yyy.com" with "subj: blah blah" due to full mailbox? Such messages are small and would not take too much space. Thus the user would know what he misses, urging him to clean his mailbox. Thank you in advance. -- Karolis

[Dovecot] [PATCH] auth: Fixed mech_winbind_ntlm by using mech_winbind_auth_initial()
by Christian Wiese 16 Jan '11

16 Jan '11

Hi folks, attached is a trivial patch which is fixing Winbind/NTLM authentication in dovecot 2.0 series. The patch was made against 2.0.8 sources, but there should be no problem applying it onto HEAD, because 'src/auth/mech-winbind.c' wasn't touched for quite some time now ;) I tested the patch with a dovecot 2.0.8 running on linux, authenticating against a WindowsServer 2008R2 Enterprise using ntlm_auth/winbind (from current stable samba 3.5.6). I successfully tested NTLM authentication for IMAP and POP3 (with and without STARTTLS) using following MUAs for the test: - Thunderbird 3.1.7 (Linux X86-64) - Outlook Express 6.00 (Windows XP Pro Qemu-KVM) Cheers, Chris Patch Description: In changeset 9002 a new function named mech_winbind_auth_initial() was introduced, but only the mech_winbind_spnego module part was changed to finally use this function. The mech_winbind_ntlm module part was not properly adapted which leads to a non functioning NTLM authentication mechanism while using winbind, because it will never call the `ntlm_auth` helper. The simple fix is to replace mech_generic_auth_initial() with mech_winbind_auth_initial() as auth_initial "hook" when setting up the mech_winbind_ntlm module, like it is done in the mech_winbind_spnego module. References: - Changeset 9002: http://hg.dovecot.org/dovecot-2.0/diff/9d0037a997f4/src/auth/mech-winbind.c

[Dovecot] Seeing other people subscribed non-shared mailboxes
by Thomas Hummel 16 Jan '11

16 Jan '11

Hello Timo, With dovecot-2.0.8/Maildir, in a simple shared mailboxes setting I noticed the following : - user "doveimap" has 2 mailboxes : "Common" and "Private" - he shares only the "Common" mailbox to user "dovepop" doing : x setacl "Common" dovepop lrwstipekxacd x OK Setacl complete. - he subscribed to both x lsub "" * * LSUB () "." "Trash" * LSUB () "." "Common" * LSUB () "." "Private" x OK Lsub completed. I'm not realy sure if the fact that "dovepop" can see doveimap's subscribed "Private" mailbox in the "#Shared" namespace is legitimate or not : x login dovepop xxxxx x OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT IDLE CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS ACL RIGHTS=texk] Logged in x list "" * * LIST (\HasNoChildren) "."

"#shared.doveimap.Private" x OK Lsub completed. x logout Is this the way it's supposed to work ? My setup is : namespace { type = shared separator = "." prefix = "#shared.%%u." location = maildir:/courriel/boites/%%u:INDEX=/var/dovecot-2/indexes/%1u/%u/shared/%%u:CONTROL=/courriel/meta/%%u # Use the default namespace for saving subscriptions. # subscriptions = no # hidden = no # list = no list = children } # pwd /courriel/boites/doveimap # cat dovecot-acl-list 1294755382 Common # cat .Common/dovecot-acl user=dovepop akxeilprwts # cat .Private/dovecot-acl cat: .Private/dovecot-acl: No such file or directory Also, I'm not sure I correctly understand what "Use the default namespace for saving subscriptions." option is. Is it just the location of the subscription file for mailboxes subscribed in the shared namespace ? Where would it be if set to "yes" ? Thanks. -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

[Dovecot] dovecot lda and quota plugin with mysql
by J4 16 Jan '11

16 Jan '11

Dear all, I have postfix delivering to dovecot lda (via spamassinassin). I have configured the quota plugin, but it does not seem to respect the details in the quota table in mysql. The query I have used looks correct to me, and the user can connect to the database. I wonder if someone might put me straight on the misconfiguration. Best wishes, j. # Relevant portions of dovecot -n: mail_plugins: quota imap_quota lda: log_path: auth_socket_path: /var/run/dovecot/auth-master postmaster_address: postmaster(a)test.info mail_plugins: sieve quota plugin: quota: dict:user::proxy::quotadict dict: quotadict: mysql:/etc/dovecot/dovecot-dict-quota.conf # cat /etc/dovecot/dovecot-dict-quota.conf connect = host=localhost dbname=fred user=fred password=freddy map { pattern = priv/quota/storage table = quota username_field = username value_field = bytes } map { pattern = priv/quota/messages table = quota username_field = username value_field = messages } # mysql table mysql> select * from quota; +-----------------------------+-----------+----------+ | username | bytes | messages | +-----------------------------+-----------+----------+ | root(a)test.info | 19524 | 18 | | bob(a)test.info | 9420 | 6 | | test(a)klunky.co.uk | 4662 | 4 | | bob1(a)test.info | 19284 | 13 | | bob2(a)test.info | 173906172 | 5702 | | postmaster(a)test.info | 10587 | 9 | | bob3(a)test.info | 3695 | 2 | +-----------------------------+-----------+----------+ 7 rows in set (0.00 sec)

[Dovecot] Quota_rule in dovecot 1.1
by drum.lucas＠gmail.com 16 Jan '11

What's up!? Well... i'm using this packages: dovecot.x86_64 1.0.7-7.el5 quota.x86_64 1:3.13-1.2.5.el5 Squirrelmail Postfix MYSQL Centos 5.5 64 Bits I configured my dovecot.conf to leave the "TRASH" folder outside the "quota", but without success ... How do I proceed to give effect to my setup? My dovecot.conf: plugin { quota = maildir quota2 = maildir:user quota *quota_rule = Trash:ignore* quota_exceeded_message = Quota excedida. Por favor, exclua alguns emails! quota_warning = storage=95%% /usr/local/bin/quota-warning.sh 95 quota_warning2 = storage=80%% /usr/local/bin/quota-warning.sh 80 } My dovecot-sql.conf: driver = mysql connect = host=localhost dbname=mail user=mail password=mail # The new name for MD5 is MD5-CRYPT so you might need to change this depending on version default_pass_scheme = MD5 # Get the mailbox user_query = SELECT '/var/vmail/%d/%n' as home, 'maildir:/var/vmail/%d/%n' as mail, 150 AS uid, 12 AS gid, CONCAT('dirsize:storage=', ROUND( mailbox.quota / 1024 ) ) AS quota FROM mailbox WHERE username = '%u' AND active = '1' ######user_query = SELECT '/var/vmail/%d/%n' as home, 'maildir:/var/vmail/%d/%n' as mail, 150 AS uid, 12 AS gid, CONCAT('*:storage=', quota_bytes, 'B') AS quota FROM mailbox WHERE username = '%u' AND active = '1' # Get the password password_query = SELECT username as user, password, '/var/vmail/%d/%n' as userdb_home, 'maildir:/var/vmail/%d/%n' as userdb_mail, 150 as userdb_uid, 12 as userdb_gid FROM mailbox WHERE username = '%u' AND active = '1' # If using client certificates for authentication, comment the above and uncomment the following #password_query = SELECT null AS password, .%u.

[Dovecot] umask setting
by PA 16 Jan '11

16 Jan '11

Hi, I have a user called archive that gets a BCC of all incoming/outgoing email. I would like to have the email in the new/cur directories setup to be read only, is there a way to do this in dovecot 2.0.8. I know you can set the umask in the dovecot config but I believe this is a global setting. Thanks, Paul

[Dovecot] Rename public folders
by Burian, John 16 Jan '11

16 Jan '11

I've got a number of public mailboxes configured for my users. We pretty much have to use Entourage for a client, which insists on creating all new subfolders with the name 'Untitled Folder'. When they try to rename these subfolders with useful names, Dovecot returns A028 NO [CANNOT] Renaming not supported across non-private namespaces. I guess this is because renaming a subfolder could potentially break subscriptions for other users? Or is it a hard requirement from IMAP RFC? If the former, is the problem merely very complicated, but eventually fixable, or is it just intractable? We're using Dovecot 2.0.7 from the atrpms RPM, Redhat EL 5.0. The public mailbox namespace is configured with: namespace { type = public prefix = Public/ separator = / hidden = no list = yes inbox = no subscriptions = no location = maildir:/data/imapmail/public:LAYOUT=fs } -- John Burian Systems Programmer Battelle Center for Mathematical Medicine The Research Institute At Nationwide Children's Hospital 614-355-5686 John.burian(a)nationwidechildrens.org ----------------------------------------- Confidentiality Notice: The following mail message, including any attachments, is for the sole use of the intended recipient(s) and may contain confidential and privileged information.

Interesting since imap_acl also makes dovecot segfault. Maybe there is a problem in the way Dovecot loads plugins?

In the real world of an ISP, killing 99% of all spam before it hits the storage is unthinkable. We only block spam that is guaranteed to be unwanted, mostly based on technical facts that can't ever happen in normal email. But email that our scanning system flags as probable spam, is just that, probable spam. We can not just throw that away, because in the real world, there are always, and I mean always, false positives. It is unthinkable to throw false positives away. So we have to put these emails in a spam folder in case the user wants to look at it. We block about 40% of all spam on technical grounds, our total spam percentage is 90%, so still about 80% of all customer email reaching the storage is spam. > > But in other environments throwing away all probable spam may be perfectly fine.

Currently mostly in database servers, but our experiences have been good enough that we're slowly starting to add them to more systems as even boot drives. But we're not using them yet in email storage. Like Brad we're using Netapp filers because as far as I know they're one of the few commercially available HA filesystem companies. We've looked at EMC and Sun as well, but havent found a reason to move away from Netapp. In 12 years of netapp we've only had 1 major outage that lasted half a day (and made the front page of national news papers). So, understand that bit. Major outages make it to national news papers for us. HA, failover, etc are kind of important to us. > > So why not build something ourselves and use SSD? I suppose we could, but it's not as easy as it sounds for us. (your mileage may vary). It would take significant amounts of engineering time, testing, migrating, etc etc. And the benefits are uncertain. We dont know if an open source HA alternative can give us another 12 years of virtually faultless operation. It may. It may not. Email is not something to start gambling with.

Certainly indexes are a prime target for SSD drives. But when the director matured, we started using the director and the netapp for indexes again. I may still build my own NFS server and use SSD drives just for indexes, simply to offload IOPS from the Netapp. Indexes are a little less scary to experiment with. > > So, if you're in the position to try out SSD drives for indexes or even for storage, go for it.

[Dovecot] Can I get rid of the fchown log messages?
by Maarten Bezemer 16 Jan '11

16 Jan '11

Hi, Since upgrading dovecot version (from somewhat ancient to 1.2.16), I see messages in the logs like these: Jan 15 00:55:17 srv0303 dovecot: POP3(obm03): fchown(/home/obm/obm03/mail/.imap/INBOX/dovecot.index.tmp, -1, 8(mail)) failed: Operation not permitted (egid=1033(obm), group based on /var/mail/obm03) I know that this is because the mailbox in /var/mail has ownership username:mail. However, in this setup this is intentional, and quota-related (quota on inbox is enforced by Exim, not Dovecot, and kernel does group-quota but not for group mail). Also, group read rights for group mail are intentional. >From what I read on this list, it has something to do with shared folders. I did not (at least it wasn't my intention) configure users' inboxes as shared folders. So, is there a way to disable these log messages, or, to disable Dovecot's attempts to try to change the owner/group of the index/cache/log files when these are inside the user's private ~/mail folder? More specifically, is there a way to do this without changing anything to users' inbox permissions? Thanks, Maarten

[Dovecot] fs quota backend bug
by Jan Škoda 16 Jan '11

16 Jan '11

Hi, I maintain postfix mailserver with sudo enabled dovecot LDA using multiple uids. I want to enforce quotas per-unix-user (which can have multiple domains with multiple emails set up using postfixadmin), so I have set up a FS quota backend with imap_quota plugin. Unfortunately, the quota appears to work (when i disable chrooting) according to dovecot-info.log, but doesn't send anything over IMAP. I found several topics related to this bug in this mailing list, but without any reply.
