[Dovecot] Managesieve with multiple uid's
by Joseba Torre 22 Dec '10

22 Dec '10

Hi, I'm trying to setup a system with dovecot to remove the old courier one, and everything (pop3, imap, lmtp, quotas) but managesieve is working fine. It seems like it's a problem with each user having a separate uid, because I have a working similar setup with a single uid working without problems. In this system when I try to connect to the managesieve port using telnet I get no response: $ telnet localhost 4190 Trying 127.0.0.1... Connected to localhost.localdomain (127.0.0.1). Escape character is '^]'. ^] telnet> quit In the logs I see: Dec 21 14:16:30 v000148 dovecot: managesieve-login: Disconnected: Inactivity (no auth attempts): rip=10.0.4.25, lip=10.0.82.8 Dec 21 14:16:30 v000148 dovecot: managesieve-login: Error: auth: connect(login) in directory / failed: Permission denied (euid=102(<unknown>) egid=103(<unknown>) missing +x perm: /, euid is not dir owner) Dec 21 14:16:30 v000148 dovecot: managesieve-login: Error: auth: connect(login) in directory / failed: Permission denied (euid=102(<unknown>) egid=103(<unknown>) missing +x perm: /, euid is not dir owner) Dec 21 14:19:30 v000148 dovecot: managesieve-login: Disconnected: Inactivity (no auth attempts): rip=10.0.4.25, lip=10.0.82.

[Dovecot] Restarting dovecot-auth stops authentication
by Attila Nagy 22 Dec '10

22 Dec '10

Hi, The Dovecot wiki states that Dovecot's master restarts all died processes, which is good for availability. But when I kill dovecot/auth (to simulate an error condition which happened on a machine), the authentication fails with: Nov 16 14:32:40 be dovecot: imap: Error: net_connect_unix(auth-master) failed: No such file or directory It seems -albeit it gets restarted- dovecot/auth doesn't re-create its socket file. Before: # ls /var/run/dovecot/ anvil auth-worker doveadm-server anvil-auth-penalty config dovecot.conf auth-client dict empty auth-login director-admin lmtp auth-master director-userdb login auth-userdb dns-client master.pid # ps auwx | grep dovecot/auth dovecot 87455 0.0 0.0 20024 3832 ?? S 2:34PM 0:00.01 dovecot/auth # rm /var/run/dovecot/auth-master; kill 87455 # ps auwx | grep dovecot/auth dovecot 88815 0.0 0.0 20024 3776 ?? S 2:36PM 0:00.01 dovecot/auth # ls /var/run/dovecot/ anvil config dovecot.conf anvil-auth-penalty dict empty auth-client director-admin lmtp auth-login director-userdb login auth-userdb dns-client master.pid auth-worker doveadm-server I've deleted the auth-master socket because if I don't, you can't see that it's not re-created. :) Is this a normal behaviour? I understand that killing dovecot/auth is not, but Dovecot could survive this easily, if recreating and re-using the new socket file would work. And loosing dovecot/auth happens sometimes (I don't yet now why). Thanks,

[Dovecot] Moving email between folders outside of IMAP context
by Phil Howard 22 Dec '10

22 Dec '10

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

[Dovecot] shared boxes
by Tobias Daucher 22 Dec '10

22 Dec '10

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

Re: [Dovecot] doveadm "-S <socket_path>" option enabled in 2.0.8?

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

21 Dec '10

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

[Dovecot] quota issues

Hi I seem to be getting an error when quotas are enabled. Also I noticed that the quota_ rule settings don't actually get used, the only settings that are used are on the sql.conf file. Maybe I'm not understanding what the quota_rule does but should I be specifying the storage/messages values on there even though they are being read/used are on the sql.conf file only. dict { quotadict = mysql:/usr/local/etc/dovecot/dovecot-dict-quota-sql.conf } plugin { quota = dict:::proxy::quotadict quota_rule = *:storage=1M:messages=5 quota_exceeded_message = Quota exceed, please email support for further assistance. trash = /usr/local/etc/dovecot/trash.conf.ext driver = sql } Sql.conf user_query = SELECT concat('/var/vmail/%d/', maildir) as home, concat('maildir:/var/vmail/%d/', maildir) as mail, 101 AS uid, 502 AS gid, concat('*:messages=5:storage=', quota) AS quota_rule FROM mailbox WHERE username = '%u' AND active = '1' Below are the errors I'm seeing in the log.

[Dovecot] Sieve create non-existent folder

Hello, Is there a way to have a Sieve script create a non-existent folder rather than have it deliver messages to INBOX instead? I'm using Dovecot 2.0.8 with Postfix, via LMTP. Thanks!

[Dovecot] Best way to move mail to an archive
by Richard C. Cox 19 Dec '10

19 Dec '10

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

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

18 Dec '10

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

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

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

17 Dec '10

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

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

16 Dec '10

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

[Dovecot] adding servers to director_mail_servers

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

16 Dec '10

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

[Dovecot] Trying to populate dovecot with outlook contacts

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

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

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

15 Dec '10

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

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

14 Dec '10

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

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

14 Dec '10

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

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

14 Dec '10

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

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

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

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

13 Dec '10

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

[Dovecot] Question about "slow" storage but fast cpus, plenty of ram and dovecot

13 Dec '10

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

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

13 Dec '10

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

I am hoping to use extra fields to migrate certain accounts in advance for testing, and I can't find info on setting up extra fields with the "passwd" backend. Is this possible, or will I have to use another approach?

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

13 Dec '10

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