[Dovecot] "starting" dovecot
by Dave Abrahams 07 Nov '12

07 Nov '12

My system never issues the "dovecot start" command. I do, however, run /usr/local/libexec/dovecot/imap on port 9xxx. I talk to the server through port 9xxx and through the preauth tunnel. Is this arrangement OK? Are there some things that will only work if "dovecot" is invoked? Thanks, -- Dave Abrahams BoostPro Computing Software Development Training http://www.boostpro.com Clang/LLVM/EDG Compilers C++ Boost

[Dovecot] Modifying mailbox GUIDs?
by Faheem Patel 07 Nov '12

07 Nov '12

Greetings all, I can view a mailbox's GUID like so: doveadm mailbox status -u guid However, how may I *modify* a mailbox GUID? Can this be done using doveadm or some other tool? If not, how may I go about modifying the dovecot.mailbox.log (where I assume GUID data is stored)? My specific use case has to do with me wanting to modify an existing mailbox's GUID so that its messages are mirrored into a folder of the same name using "dsync mirror". (As we know, dsync utilizes GUIDs to determine mailbox uniqueness) Thanks! -- - Faheem

[Dovecot] Error: Internal quota calculation error
by Micah Anderson 07 Nov '12

07 Nov '12

Hello, I'm using 2.1.7 with seive and mysql quotas. We had an outage the other day where the database server where quotas are stored was not available for a short period of time. In dovecot land, the following types of errors occured in that scenario: Oct 26 22:19:01 grosbeak dovecot: lda(example(a)riseup.net): Error: Internal quota calculation error Oct 26 22:19:01 grosbeak dovecot: lda(example(a)riseup.net): Error: sieve: msgid=<20122132765181x.ABCCE457(a)example.com>: failed to store into mailbox 'Trash': Internal error occurred. Refer to server log for more information. [2012-10-26 22:19:01] Oct 26 22:19:01 grosbeak dovecot: lda(example(a)riseup.net): Error: sieve: script /maildir/e/example/.dovecot.sieve failed with unsuccessful implicit keep (user logfile /maildir/e/example/.dovecot.sieve.log may reveal additional details) I expect that there would be quota calculation errors as dovecot could not reach the database server, but what worried me was the 'failed to store into mailbox' message from sieve. The 'Trash' mailbox in this particular seive script is the correct location for the message to be filed into, but the worrisome message is the 'failed with unsuccessful implicit keep'. I looked through all the message-ids that reported this error and I found that the messages were properly delivered in the end, so this might be some issue interacting between sieve, dovecot and quota and just causing a scary message that can be ignored? thanks for any information you can provide, dovecot is great! micah --

[Dovecot] how to best import Evolution/Thunderbird mail into dovecot?
by Christoph Anton Mitterer 07 Nov '12

07 Nov '12

Hi. I'm migrating all my mail archive (some 60 GB) from Evolution (which is really a broken piece of software) into dovecot. Now I face the problem how to do this best... Evolution (which is still a old 2.32.x version) itself uses mbox files, in a special hierarchical structure to allow subfolders and that like. It also stores it's own status info in X-Evolution and X-Evolution-Source mail headers. Unfortunately,... much of the mail was earlier from a Thunderbird installation, which uses it's own status headers (X-Mozilla*) that were not recognised by Evolution. I have no idea which mbox subformat was always used throughout the different programs and versions... 1) Any way to check for that? To make things worse... Thunder(burden) seems to have used a modified From_ line syntax... "^From -<address> <date>$" Ideally I'd like migrate all mail into dovecot (for storage reasons again, mbox) retaining the different status flags (read, forwarded, etc.) and getting rid of the proprietary headers (of course only when they were. First thing I tried was to simply copy mail within Evolution (i.e. dragging&dropping it from the local folders to the IMAP folders from dovecot). - that preserves the status from Evolution, but doesn't restore that from Thunderbird - it clutters up the information of all From_ lines... "<address> <date>" becomes "<address of my default evolution account> <now>" - neither does it handle the special Thunderbird From_ lines - neither does it remove the Thunderbird or the X-Evolution-Source headers - if Evolution has already had corrupted index files (and this is extremely likely... as it happens even immediately during recreating all of them)... so I may loose mail So my idea was that I need a program that: - can parse all the different mbox formats (those that use the quoted ">From" style and those that use Conent-Length) - can differentiate message headers from body (so that I can drop the proprietary headers and replace them by what dovecot uses as headers) - must of course understand multiline message headers 2) Any idea for a tool like that? The meaning of the X-Evolution and X-Mozilla* headers are easy to find on the web.... so I can convert them. So I basically "just" need a tool that parses all kinds of mbox formats... allow me to drop/add headers... and spits out the rest unmodified. 3) dovecot uses some special headers like X-UID and X-IMAPD... will it create these on it's own, the first time it processes the new mbox file? I mean these headers won't be there after creation. 4) Should I drop out (during) conversion... any other mail headers.. that dovecot uses as it's own? Thanks, Chris.

Hello, My phone: Android ics 4.1.2 on galaxy nexus. And yes, stock mean the default client that come with the os in IMAP mode. I already know about that configuration parameter, but it will display two time namespace in postlogin capabilities, and so I like much more to adjust the source code to fix the issue. Yes there is k9 but I didn't like it too much, I prefer the stock client and is much important to keep compatibility with stock client then user-installed client.

[Dovecot] sieve
by Christian Rößner 06 Nov '12

06 Nov '12

Hi, is there a sieve option that can reject a mail directly without creating a new mail and sending that out? I know about reject "Reject message goes here"; but I am looking for a mechanism that can reject Mail. Postfix can use reject_unverified_recipient to connect to LMTP and ask if a mail would successfully be enqueued and will return the status gotten from the LMTP server if not. Chances are high that the mechanism would work, too, if Dovecot would know about the sieve rule, while getting a connection on LMTP. Does Dovecot know all rules at this point or is sieve handled after the mail has already been accepted?

[Dovecot] Android ICS stock client and IMAP Capability issue.
by Massimiliano Cianelli 06 Nov '12

06 Nov '12

Hi, My setup: Dovecot 2 latest, installed to replace courrier IMAP, and off course configured with the dot separator and all folder under INBOX.*. The problem: My phone was driving me mad during the test, due that it will only recognize Inbox. How found the solution: I've started sniffing IMAP traffic on my server and ended up with one difference: On courier it ask for namespace, on dovecot it won't. I gives a better look, and noticed that courier show namespace capability on prelogin banner, adding it too solved the problem. Reason: Android ICS stock client seems do not honor the capability gived after the login. Request: Maybe is possible to put namespace capability in prelogin banner for the next version? That will solve trouble with a setup like the mine and android stock email client. Thank you, Best regards Sent from Galaxy Nexus

[Dovecot] Quota
by Christian Rößner 05 Nov '12

05 Nov '12

Hi, is it possible to ask Dovecot for a users quota by talking to the Dovecot server over TCP? I know about doveadm quota -u <user>, but I would like to know, if I can query for that over a network connection (on the Postfix ML they suggested writing a policy service that checks quota. Postfix is not always on the same server as Dovecot is). Does the LMTP protocol give that information somehow? I am not so familiar with LMTP. Or some Unix-Socket to query that could also be configured as inet_listener?

Hi. Even new mails delivered by my MDA don't get the ,S= and ,W= fields set... (but when I "upload" a mail via IMAP to dovecot, they are set) Is there some place in dovecot where I need to enable this? Or would it be the MDA that has to calculate and set this already when placing a file in ./new? Thanks, Chris.

I don't know if Dovecot takes advantage of this in any way though. Joseph Tam <jtam.home(a)gmail.com>

Dear listmembers. I have the following login_log_format_elements = service=%s user=<%u> session=%{session} method=%m rip=%r lip=%l mpid=%e %c %k Maybe I have overseen the config option to add the %{session} also to the logout line. Here a example from my log: ### Nov 3 00:46:43 <HOST> dovecot: imap-login: Login: service=imap, user=<USER>, session=ETV8v4vNfwB/AAAB, method=CRAM-MD5, rip=127.0.0.1, lip=127.0.0.1, mpid=14874, TLS, TLSv1.1 with cipher AES256-SHA (256/256 bits) zlib compression Nov 3 00:46:43 external dovecot: imap(USER): Disconnected: Logged out in=15649 out=80199 ### Thanks for help and answers.

Hi Javier, yes i see. Storage for now is just a 3tb sata2 hdd, so i guess that write performance is around 100 MB/s What do you think about that ?

[Dovecot] dovecot dimensioning
by mancyborg＠gmail.com 01 Nov '12

Hi All, first post here, nice to meet you :) I've been using dovecot + postfix + clamav + spamassassin for years but always with few users. Now i must build a server for 1500 users, they will use various email software (thunderbird, outlook, ..) the webmail (i'm not sure if squirrelmail or roundcube) and blackberry devices (with the BIS service). There will be around 1000 domains (virtual_domains) and postfix will read its users and domains from mysql. Let's say that they will send and receive around 5000 emails per hour (10K in total per hour). I was thinking to use karspersky server instead of clamav. I already have the hardware, it is a server with 4 physical cpu (Intel Xeon E5504 @ 2.00GHz) and 24 gb of ram, do you think it is enough ? Thanks for supporting, regards and have a nice day, Mike

I'm compiling as I normally do. The config line for Dovecot is: configure --with-ldap --with-ssl --with-bzlib --with-zlib --with-stemmer --with-lucene --with-ldap followed by make & make install Then a 'configure' for Pigeonhole,

[Dovecot] IMAP proxy between Office 365 client/Sun Messaging Server
by John Dalbec 31 Oct '12

31 Oct '12

I would like to be able to migrate messages from existing end-user accounts on Sun Messaging Server to Office 365 using an administrator login and password. Unfortunately the migration tool for Office 365 doesn't support SASL AUTHENTICATE PLAIN login. The online documentation I've found suggests that I should be able to configure dovecot as an IMAP proxy and have it log in to Sun Messaging Server with AUTHENTICATE PLAIN and encode_base64("user\0admin\0adminpw") in response to a login from the Office 365 migration tool. I'd like to configure dovecot to run only the IMAP proxy if possible. I was thinking of setting all accounts to use the same (strong) password in the proxy. Would anyone be willing to share a sample configuration? Thanks, John Dalbec ellucian Luminis system administrator Youngstown State University

[Dovecot] Unable to get Managesieve working
by Cliff Dunn 31 Oct '12

31 Oct '12

I have Roundcube webmail (v. 0.8.2) running with the managesieve plugin (v. 5.1). I am able to create sieve rules without any problems in Roundcube, but incoming mail is not being processed with the rule I specify. I suspect there is something that isn't configured correctly in dovecot, but unfortunately I am unable to find a resolution online and my very limited knowledge of dovecot isn't allowing me to solve this problem on my own.

[Dovecot] Dovecot stops to work - anvil problem
by FABIO FERRARI 31 Oct '12

31 Oct '12

Hi all, we have a problem about anvil, it seems that when we have a high load the dovecot stops to work. Sometimes it is sufficient to make a dovecot reload, but sometimes we have to restart it. These are the lines related to anvil in the dovecot.log: [root@secchia ~]# grep anvil /var/log/dovecot.log | more Oct 26 11:13:55 anvil: Error: net_accept() failed: Too many open files Oct 26 11:14:32 imap-login: Error: net_connect_unix(anvil) failed: Resource temporarily unavailable Oct 26 11:14:32 imap-login: Fatal: Couldn't connect to anvil Oct 26 11:14:33 pop3-login: Error: net_connect_unix(anvil) failed: Resource temporarily unavailable Oct 26 11:14:33 pop3-login: Fatal: Couldn't connect to anvil [...] (many lines like these) Oct 26 12:01:10 pop3-login: Fatal: Couldn't connect to anvil Oct 26 12:01:18 auth: Error: read(anvil-auth-penalty) failed: Connection reset by peer Oct 26 12:01:18 auth: Error: read(anvil-auth-penalty) failed: Connection reset by peer Oct 26 12:01:18 auth: Error: net_connect_unix(anvil-auth-penalty) failed: Connection refused Oct 26 12:01:18 auth: Error: net_connect_unix(anvil-auth-penalty) failed: Connection refused Oct 26 12:01:18 auth: Error: read(anvil-auth-penalty) failed: Connection reset by peer Oct 26 12:01:18 auth: Error: net_connect_unix(anvil-auth-penalty) failed: Connection refused And this is the output of the doveconf -n: [root@secchia ~]# doveconf -n # 2.0.1: /etc/dovecot/dovecot.conf # OS: Linux 2.6.18-308.11.1.el5 x86_64 Red Hat Enterprise Linux Server release 5.8 (Tikanga) xfs auth_cache_size = 1024 auth_cache_ttl = 21600 s auth_debug = yes auth_debug_passwords = yes auth_master_user_separator = * auth_mechanisms = plain login auth_socket_path = /var/run/dovecot/auth-userdb auth_verbose = yes base_dir = /var/run/dovecot/ disable_plaintext_auth = no hostname = mail.unimore.it info_log_path = /var/log/dovecot.log lda_mailbox_autocreate = yes log_path = /var/log/dovecot.log mail_debug = yes mail_location = maildir:/cl/mail/vhosts/sms.unimo.it/%Ln/Maildir mail_plugins = $mail_plugins quota mailbox_idle_check_interval = 60 s mbox_write_locks = fcntl namespace { inbox = yes location = prefix = INBOX. separator = . type = private } passdb { args = /usr/local/etc/dovecot.masterusers driver = passwd-file master = yes } passdb { args = dovecot driver = pam } plugin { quota = maildir:User quota quota_exceeded_message = Quota exceeded (mailbox is full) quota_rule = *:storage=200MB quota_rule2 = *:messages=100000 quota_rule3 = INBOX.Trash:storage=+100M quota_warning = storage=90%% quota-warning 90 %u quota_warning2 = storage=85%% quota-warning 85 %u quota_warning3 = messages=95%% quota-warning 95 %u quota_warning4 = messages=80%% quota-warning 80 %u setting_name = quota } postmaster_address = postmaster(a)unimore.it quota_full_tempfail = yes service anvil { client_limit = 199999 process_limit = 199999 } service auth { client_limit = 14500 unix_listener auth-userdb { mode = 0600 user = vmail } } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 } process_limit = 5000 } service imap { process_limit = 5000 } service pop3-login { inet_listener pop3 { port = 110 } inet_listener pop3s { port = 995 } } service pop3 { process_limit = 1024 } service quota-warning { executable = script /usr/local/bin/quota-warning.sh unix_listener quota-warning { group = vmail user = vmail } user = dovecot } ssl_ca = </etc/pki/tls/certs/ca_unimore_tcs.pem ssl_cert = </etc/pki/tls/certs/cert-852-mail.unimore.it-cluster.pem ssl_key = </etc/pki/tls/certs/mailcluster.key userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } verbose_ssl = yes protocol lda { mail_plugins = $mail_plugins quota } protocol imap { mail_plugins = $mail_plugins imap_quota } protocol pop3 { mail_plugins = $mail_plugins quota pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_uidl_format = %08Xu%08Xv } [root@secchia ~]# And these are the limit settings in the OS: * soft nofile 131072 * hard nofile 131072 Have someone had the same problem? thanks in advance Fabio Ferrari

[Dovecot] lmtp out of memory - raw backtrace
by Daniel Parthey 31 Oct '12

31 Oct '12

Hi, Our setup: - 4 hosts with director and mailbox instance - delivery via director lmtp into mailbox lmtp - mailbox format: mdbox - storage on NFS - OS: Linux 2.6.32-44-server x86_64 Ubuntu 10.04.4 LTS - Dovecot 2.1.10 - Pigeonhole 0.3.3 We're getting strange "out of memory" lmtp errors/backtrace with dovecot 2.1.10 accompanied by high load caused caused by a lot of lmtp deliveries to one user. First action would be to increase vsz_limit to a higher value, but I just want to make sure there is no bug - before blindly increasing this limit. I think it should not crash and corrupt mdbox, even if memory limit is reached: Oct 29 20:14:56 10.129.3.249 dovecot: lmtp(26698, user1(a)example.org) Fatal: pool_system_realloc(16777216): Out of

[Dovecot] POP3 Proxy : user format not accepted
by Christian Gregoire 30 Oct '12

30 Oct '12

Hello, I want to use Dovecot as a POP3 proxy (http://wiki.dovecot.org/HowTo/ImapProxy) All is working fine on my sample platform, except that I have plenty (several thousands) of users that login using local_part#domain, instead of local_part@domain, which is an old setting on my POP3 server. And in that case, Dovecot returns 'Authentication failed'. Here is my proxy table : mysql> select * from tbl_proxy; +--------------------+-------------+--------------------+ | user | host | destuser | +--------------------+-------------+--------------------+ | christian(a)mydom.fr | 10.10.100.1 | christian(a)mydom.fr | | christian#mydom.fr | 10.10.100.1 | christian(a)mydom.fr | +--------------------+-------------+--------------------+ If I login on the Dovecot proxy with the '@' version, everything is fine : root : ~> telnet 10.10.100.24 110 Trying 10.10.100.24... Connected to 10.10.100.24 (10.10.100.24). Escape character is '^]'. +OK Dovecot ready. user christian(a)mydom.fr +OK pass azerty42 +OK christian#mydom.fr has 3 messages (3561 octets) And MySQL logs show the query : 121030 12:55:28 3 Query SELECT NULL AS password, host, destuser, 'Y' AS nologin, 'Y' AS nodelay, 'Y' AS proxy, 'Y' AS nopassword FROM tbl_proxy WHERE user = 'christian(a)mydom.fr' If I login on the Dovecot proxy with the '#' version, it fails : root : ~> telnet 10.10.100.24 110 Trying 10.10.100.24... Connected to 10.10.100.24 (10.10.100.24). Escape character is '^]'. +OK Dovecot ready. user christian#mydom.fr +OK pass azerty42 -ERR Authentication failed. And nothing shows up the the MySQL logs. If I login directly on the POP server with the same credentials, no problem : root : ~> telnet 10.10.100.1 110 Trying 10.10.100.1... Connected to 10.10.100.1 (10.10.100.1).

Authenticate yourself. user christian#mydom.fr +OK Password required for christian#mydom.fr pass azerty42 +OK christian#mydom.fr has 3 messages (3561 octets) Any idea ? Is the '#' not internally supported in the user login by Dovecot ? Thanks in advance. Christian

[Dovecot] Dovecot does not update acl_shared_dict file
by Chris Smith 30 Oct '12

30 Oct '12

Hi all, Firstly, thanks for all your effort with this software. Much appreciated. I am having a slight issues trying to enable reading of other users mailboxes. The docs are a little sparse for those that aren't mailadmin heros, I wonder if anyone could please help me see where I am going wrong. I would like to allow some users to list and read the mailboxes of others. E.g: When User1 logs in, they are presented with a list of their own folders, and those of User2, User3, etc to which they have (e.g. read/list) access I followed the instructions on the wiki (for Version 1.X)- there are two concepts here: 1. Grant some [e.g. list/read] access on a mailbox folder to a particular user 2. Enable the acl_shared_dict to allow dovecot to track (and display to IMAP clients) the folders to which they have access. This will take the form of a BDB file: /var/lib/dovecot/shared-mailboxes.db This file can only be updated by using the SETACL command. *This is where I have the problem*. The SETACL command does nothing. No matter how hard I try, I cannot get dovecot to update this file. The only indication I have that the file exists and is readable by dovecot is the disappearance from the logs of the line: No acl_shared_dict setting - shared mailbox listing is disabled So I can see that dovecot knows the file is there because it does not complain any more. The file is there (because I created it myself, although it is empty: size = 0), and in a moment of weakness I made sure it could be updated (this will be changed back!): ls -l /var/lib/dovecot/shared-mailboxes.db -rwxrwxrwx 1 dovecot dovecot 0 2012-10-30 12:27 /var/lib/dovecot/shared-mailboxes.db But if I try to update the ACL, absolutely nothing happens: [ > command ] [ < reply ] > telnet localhost 143 < * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE STARTTLS AUTH=CRAM-MD5] Email server > a login [User2] [pass] < a OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE 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 ACL RIGHTS=texk] Logged in > a SETACL Inbox [User 1] rl < a OK Setacl complete.

Hi All, With the below setting (cropped), the ssl certificate(signed by godaddy) don’t seems to work. It will still ask me if I want to accept this certificate.

[Dovecot] Save/restore IMAP session state
by Timo Sirainen 30 Oct '12

30 Oct '12

Some future Dovecot version will have "imap-idle" processes where IDLEing IMAP connections get moved, so the system wouldn't waste so much memory for all the IDLEing imap processes. A week ago I thought I'd see how easy it would be to implement this. I got a basic proof of concept working as a "X-STATE" command. Save the state: a x-state * STATE AQDLW45QdwAAAAMAAABuAQAAAAAAAFAcffYAPHnpFctbjlDbYQAAcEmzCwAA a OK State exported. Restore the state: b x-state AQDLW45QdwAAAAMAAABuAQAAAAAAAFAcffYAPHnpFctbjlDbYQAAcEmzCwAA b OK State imported. This could also be used to implement quick session state restoring for webmails (as suggested by Michael Slusarz). For getting the imap-idle process there would have to be code that: * triggers the session saving when process is IDLEing * figures out what filesystem paths the imap-idle should be looking at (i.e. paths to selected mailbox's dovecot.index.log file and maybe for e.g. maildir new/) * send the session state string, paths and imap connection fd to imap-idle process via UNIX socket * implement the actual imap-idle process * implement a way for imap-idle process to send back the state and connection fd to restore the imap process The patch is ugly and still missing many things. Anyway I thought I'd include it here just in case someone was really eager to continue implementing it. :) I'm not sure when I'll have time for it. A full patch would probably have to have some session_save()/session_restore() functions in lib-storage API. But a quick and dirty way is possible to implement for v2.1 as well, as long as some IMAP extensions aren't used (most importantly rfc5267).

[Dovecot] does dovecot interpret any mail headers specially with maildir?
by Christoph Anton Mitterer 30 Oct '12

30 Oct '12

Hi. For mbox, http://wiki2.dovecot.org/MailboxFormat/mbox#Dovecot.27s_Metadata lists a numer of mail headers: - X-IMAPbase - X-IMAP - X-UID - Status - X-Status - X-Keywords - Content-Length that are treated specially by dovecot. It also suggests, that these should be stripped by the LDA (I guess in order that someone sending you such mail cannot set the status or keywords, or even "attack you" by setting a bogus Content-Length). I wondered, when using maildir, are there any headers that dovecote would treat specially, too? And which I therefore should strip? Thanks, Chris.

[Dovecot] No failover from director to backend?
by Patrick Westenberg 29 Oct '12

29 Oct '12

Hi everyone, short version: Is there no built in failover mechanism for the director service to handle a backend failure? Long version: I have a frontend server running the director service and two backends. Due to maintenance I had to shut down one of the backends which caused connection errors for the users being directed to this backend. I was very surprised as I expected the director to redirect these users to the remaining backend. Am I wrong or is the director not working as expected?

[Dovecot] INBOX permissios woes
by Josep L. Guallar-Esteve 29 Oct '12

29 Oct '12

Hello, I have a dovecot system that uses winbind authentication against Active Directory. I set it up by following the directions in the wiki. That works great. When a new user receives an email, the inbox is created with permissions 600 (rw- --- --) and ownership user:mail , even though I did chmod 02770 /var/spool/mail. And then, when dovecot tries to access the inbox, it throws the error: Oct 29 13:47:59 imap-login: Info: Login: user=<user1>, method=PLAIN, rip=10.0.0.6, lip=10.0.0.26, mpid=29047, secured Oct 29 13:47:59 imap(user1): Error: stat(/var/mail/user1) failed: Permission denied Oct 29 13:47:59 imap(user1): Error: stat(/var/mail/user1) failed: Permission denied Accessing users' Sent, Trash, creating new folders.... all that works fine.

[Dovecot] Overlapping userdb/passdbs
by James Devine 29 Oct '12

29 Oct '12

I have an ldap server for which each entry includes the email address and the username portion of the email address for authentication. Authentication works by username if the username is unique among all the entries. I need to now add some users which must authenticate even if the username is not unique. I figured one way to do this would be to add a second user/pass db which puts further restrictions on the ldap query to make it unique for those users. This doesn't seem to work however as if the user is found in the first ldap query but the password does not match it does not try the second. I would use the password as part of the query but this setup requires me to allow the client to hash the password. Is there a way to do this? Or maybe I am approaching the problem wrong.

[Dovecot] Can Dovecot authenticate against an external email server?
by Marc Perkel 29 Oct '12

29 Oct '12

Just wondering if anyone has done this. I have a spam filtering service where I am now storing spam for users I filter for. It's a filter and forward service so I don't control the recipient's email server. What I would like to do somehow is have the user enter their email address and password and then look up their POP/IMAP server from a database and try to authenticate from it. If sucessful then the user will be able to access their stored spam using Dovecot and Squirrelmail. Any suggestions? Thanks in advance

[Dovecot] Auth caching and password changes
by Angel L. Mateo 29 Oct '12

29 Oct '12

Hello, In my system I have configured auth caching. The problem I have is that whenever a user changes his password, he/she can't login to dovecot after a while and the scenarios described at http://wiki2.dovecot.org/Authentication/Caching are not applied. I have tried also with "doveadm auth cache flush <login>", but it didn't work. He also could to login again if he waits for a time or if I run "doveadm auth cache flush" in the server, flushing all auth information from cache. I have attached the log I had when I changed my password (and suffered the problem). I have attached my doveconf -n too. -- Angel L.

[Dovecot] Configuring Dovecot & Snarf plugin for the first time
by Jeffrey Ross 29 Oct '12

29 Oct '12

I've been using uw-imap for some time on my linux system and have been running into issues with it so I've decided to move to Dovecote, so far it seems to have solved the issues I've been having however I need/want to move the incoming emails out of /var/spool/mail/{user} in the same (or similar fashion) that uw-imap did, and I found the snarf plugin. However whenever I enable the snarf plugin using the example on the wiki page my email is not loaded and when I remove my configuration for snarf my email re-appears. Based upon what I can tell the snarf plugin is either not loading (but I see it listed in the logs) or simply not working (which is probably because its not configured properly). The system is Fedora 16 (x86_64), the MTA is Exim, and Dovecot is 2.0.21 (version supplied with Fedora). I know I'm making a newbie mistake. Any guidance would be appreciated.

[Dovecot] LDA without lookup as non-root?
by E.B. 29 Oct '12

29 Oct '12

Hello, I'm having some problems getting LDA to work without userdb lookups and have a few related questions. This system has all users in MySQL, each user with unique UID/GID, no local users at all. Installation is from apt-get. 1) If LDA is invoked without lookups, is it correct to assume that the "service auth" and "service auth-worker" can be completely removed from dovecot master configuration? (I have tried commenting them out and logging into IMAP, which seems to work, not sure if anyone else needs the auth service) 2) If LDA is invoked without lookups, will I be unable to use Dovecot quota plugin? Does it need to have a user lookup to get quota info? (haven't added quota support, need to take this one step at a time) 3) The interesting part -- I am invoking LDA from Maildrop. See: http://thread.gmane.org/gmane.mail.imap.dovecot/65473 So when invoked, Maildrop has already dropped to the destination UID/GID and the needed paths are available in the environment. However, using as many permutations of calling LDA as I can think of (based on http://wiki2.dovecot.org/LDA ), I always get this: (command line usage error. Command output: lda: Fatal: Couldn't lookup our username (uid=2500) ) The UID is correct for the target user. If I add "-d $LOGNAME" to my LDA callout, I get permission denied on the userdb lookup, which I guess is another issue to work out if I want to go with lookups. But right now I am trying not to. Why does LDA seem to try for a lookup even when I follow the wiki instructions how to call it without a lookup? 3.5) Related question, my users have separate homedir and maildir, both paths are looked up by Maildrop. I think I need to call LDA with "HOME=$DEFAULT dovecot-lda -f $FROM". Is this correct?

[Dovecot] mail open slowly
by Bernics Gábor | Penta Unió Zrt. 29 Oct '12

29 Oct '12

Hello, I have a dovecot IMAP server (relative small hardware: HP Microserver with 6 Gbyte RAM, linux soft RAID1 with 2x 7200 SATA disk) with 100 Gbyte maildirs. Server works fine but sometimes I can open mails slowly (5-10 sec), typical with new mails. It's intresting when I open an another old mail (with 0 sec wait), after new mail open quickly. Is it dovecot mail indexes or I/O problem? Load and CPU use is small typical 0.10, 10%, I see small IO wait. Debian 6.0, Dovecot 1.2.15, fsync and nmap is disable Best Regards, Gabor

[Dovecot] Active Directory 2003 user database and passwords with special characters
by Boris PINON 29 Oct '12

29 Oct '12

Hello everybody, As explained in the topic, i have troubles with authentication of my users. First of all, sorry for my poor english... I'm running dovecot v1.2.15 on a Debian 6 64bits server up to date. My users database is an Active Directory 2003 (it's important to know that because Active Directory can't retrieve users passwords, you have to bind LDAP with a domain administrator). So, i'm using userdb ldap for authenticated my users and it works ! BUT... When an user having a password with special characters like " ² ° § µ à é è ç à â ê î ô û ù ä ë ï ö ü ", authentication does not work. And in my log file : MY_SERVER | mail/info | dovecot | 2012/08/27 10:42:14 | auth(default): cache(my_user,192.168.7.127): plain(RU0975é*) != 'RU0975Ã©*' As you can see, the character é has been replaced by Ã©.

[Dovecot] Problem with sieve. dovecot 2.0.17
by Eliezer Croitoru 28 Oct '12

28 Oct '12

Since I have lots of filtering rules in thunderbird I was thinking of using sieve instead. I want to filter incoming mail into subdirectories. like "from" store at folder "old". the script is: require ["fileinto", "envelope"]; if envelope :is "from" "eliezer(a)test.dom" { fileinto "old"; } else { # The rest goes into INBOX # default is "implicit keep", we do it explicitly here keep; } the result is that the mail is stored in two folders instead of just one, INBOX and old. the logs shows: Oct 23 17:12:26 lda(eliezer(a)ngtech.co.il): Debug: sieve: executing script from /home/vmail/domain/eliezer/home/.dovecot.svbin Oct 23 17:12:26 lda(eliezer(a)test1.dom): Info: sieve: msgid=<5086B3C9.5030909(a)test.dom>: stored mail into mailbox 'INBOX' Oct 23 17:12:26 lda(eliezer(a)test1.dom): Info: sieve: msgid=<5086B3C9.5030909(a)test.dom>: stored mail into mailbox 'old' from unknown reason(or I didnt understood how sieve works?) plugin section from dovecot -n plugin { ... sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_extensions = +vnd.dovecot.debug +imapflags +relational +comparator-i;ascii-numeric } Thanks, Eliezer

[Dovecot] Locking /var/mail/user issue with postfix and dovecot
by Robert JR 27 Oct '12

27 Oct '12

Hello, I have a question regarding mailbox locking and hope any one can help me to better understanding the locking of mbox My Postfix lock option is fcntl dotlock mailbox_delivery_lock = fcntl, dotlock virtual_mailbox_lock = fcntl, dotlock My Dovecot lock option is fcntl only mbox_write_locks = fcntl mbox_read_locks = fcntl now, when user is download a large mail (20 MB) for example, dovecot locks /var/mail/user with fcntl until the users finish downloading the mail ok here comes my question. While the user is downloading the mail , a mail arrives so postfix make some thing weird 1- Postfix creates /var/mail/user.lock for 5 secs , then postfix defer the mail with reason that the /var/mail/user is locked and then delete the /var/mail/user.lock (after 5 secs) My question is ? why postfix create user.lock although it shouldn't because already dovecot fcntl it … 1- Dovecot locks /var/mail/user using FCNTL 2- Posttix at the same time tries to FCNTL /var/mail/user .. but it fail since dovecot already fcnl it. 3- Postfix at the same time add dot lock /var/mail/user for 5 secs then remove the lock. the question is how come postfix dot lock /var/mail although it couldn't FCNTL the file in the first place ??????? what i was expecting is 1- Dovecot locks /var/mail/user using FCNTL 2- Postfix tries to FCNTL /var/mail/user 3- POSTFIX WILL NOT CREATE DOTLOCK file unless the FCNTL is released by dovecot!!!! Please advise if postfix will dot lock the file even if it couldn't FCNTL the file in the first place…… Regards

26 Oct '12

Hi I've added a server-side feature where authenticated customers sending through our SMTP server have their outbound mail copied to their Sent folder (like Gmail does). The delivery script called by qmail calls dovecot-lda to deliver it to the user's Sent folder. The problem now, is that the Sent folder shows the mail as unread, which MUAs flag (and notify, in the case of some). I've searched the docs and mailing list, but can't find an option to tell dovecot-lda to mark the mail being delivered, as seen/read. If I've missed something, please let me know. If not, then I think it might be a good idea to add a feature to dovecot-lda permitting one to specify delivery to the ./cur subfolder of a Maildir, instead of ./new. Thanks

[Dovecot] Shared folders not shown if "INBOX.shared.%.%" is used with dovecot 2.1.10
by Christoph Bußenius 26 Oct '12

26 Oct '12

Hi, Thunderbird uses the following IMAP command to list shared folders: . list "" INBOX.shared.%.% Dovecot 2.1.10 does not list any folders in response to this command. Dovecot 2.0.21 does list them: * LIST (\HasNoChildren) "." "INBOX.shared.user1.folder" . OK List completed. Both versions list the folders if "*" is used instead of "INBOX.shared.%.%". Because of this issue, shared folders are not shown in Thunderbird. The ACL of the folder in question is ACL "keilrwtscd" for user1 (who is trying to access them using Thunderbird). config: # 2.1.10: /usr/local/dovecot/etc/dovecot/dovecot.conf # OS: Linux 2.6.32-42-server x86_64 Ubuntu 10.04.4 LTS disable_plaintext_auth = no mail_gid = vmail mail_location = mdbox:~/mail mail_plugins = acl mail_uid = vmail namespace { inbox = no list = children location = mdbox:%%h/mail prefix = INBOX.shared.%%u. separator = . subscriptions = no type = shared } namespace default { inbox = yes location = prefix = INBOX. separator = . type = private } passdb { args = scheme=CRYPT username_format=%u /usr/local/dovecot/etc/dovecot/users driver = passwd-file } plugin { acl = vfile acl_shared_dict = file:/mail/shared-mailboxes } protocols = imap pop3 service auth { unix_listener auth-userdb { group = vmail mode = 0660 } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = /usr/local/dovecot/etc/dovecot/users driver = passwd-file } protocol imap { imap_client_workarounds = tb-extra-mailbox-sep mail_max_userip_connections = 20 mail_plugins = acl imap_acl acl } Cheers, Christoph -- Christoph Bußenius Rechnerbetriebsgruppe der Fakultäten Informatik und Mathematik Technische Universität München +49 89-289-18519 <> Raum 00.05.040 <> Boltzmannstr. 3 <> Garching

[Dovecot] Small issue with "submission host"
by Raphael Ordinas 26 Oct '12

26 Oct '12

Hi everyone, I'm facing a small issue with the lda/lmtp "submission_host" feature in dovecot 2.0.14. When sending mail to MTA (in case of sieve filter forwarding for example), dovecot pass a RCPT TO command just after the EHLO. He's missing the MAIL FROM command. Therefore, my MTA show me a warning like this : "improper command pipelining after EHLO". How can i solve that ? Regards, Raphael

[Dovecot] Public folders and groups
by b m 26 Oct '12

26 Oct '12

Currently I have dovecot working with Active Directory authentication and public folders with acl. In acl I have the users I want to access the public folders. It'll be easier for me to use one group instead of 50 users but I can't get it to work. From where does dovecot get the "group" attribute for a user? Can it read the groups that a user belongs from AD?

[Dovecot] Snarf plugin
by Jeffrey Ross 26 Oct '12

26 Oct '12

I've now upgraded dovecot from 2.0.21 to 2.1.10 and the good news is I no longer see dovecot crashing when loading the snarf plugin however snarf still does not do anything except make the inbox disappear. I've come to the conclusion that either snarf does not actually work, possible, but I doubt it, or more likely I have a configuration issue preventing it from working. The system is simple, all email is stored in /var/spool/mail/{username} and I want all the mail moved to ~/mbox when the user logs in via imap, similar to uw-imap. Any guidance would really be appreciated.

[Dovecot] Creating Maildir and populating with emails via external Python process
by Bradley Rintoul 26 Oct '12

26 Oct '12

Hello: I'm using Dovecot to provide IMAP services for Thunderbird clients. The user's mail is stored in Maildir format and the individual emails which the user "receives" are actually downloaded and put into the Maildir "repository" using a Python email client (POP3 client). I am trying to create the dovecot-uidlist file and maintain the "next UID" value within it, but I am having trouble with the UIDVALIDITY and the 128 bit mailbox global UID among other things. How can I "seed" a dovecot-uidlist file with these values..? Sorry if the information is not much to go on, please let me know what more information you might need to help point me in the right direction. Thanks, B. RIntoul

[Dovecot] spamc can't seem to call /usr/lib/dovecot/deliver

Hi, My server uses a system comprised of postfix, dovecot and dspam to filter and deliver mail.

[Dovecot] dovecot auth against AD on samba4
by Carsten Laun-De Lellis 24 Oct '12

24 Oct '12

Hi group I am currently running a mail server on ubuntu 11.04 with postfix 2.8.5, dovecot dovecot 2.0.13 and openldap 2.4.23. I have now read about sogo and I am thinking about installing it because of it's native outlook support capabilities. The ZEG appliance wouldn't be an option for me because I use a virtual server from a provider where I can't install my own vm or even an iso. When I go thru the documentation there is a part with installing OpenChange based on samba4. As far as I understood the OpenChange authentication is against the samba4 AD. Actually there is no support in syncing the AD against an OpenLdap Server and I would have to change the OpenLdap port because the AD is listening on port 389. To change the port wouldn't be a big deal, but what i was thinking about to run the dovecot auth also against the samba 4 AD. I searched around on the internet but didn't find a doc yet how to do that. Does anyone here could provide me with a link or a how-to ? Thanks very much in advance.

[Dovecot] Clarifications on Pigeonhole and MySQL lookups
by Sandro Tosi 24 Oct '12

24 Oct '12

Hello, we're scouting if it's possible to use Pigeonhole (currently v0.3.1, as this will be provided with an upcoming Debian package) with MySQL dict lookups with the mail setup we're designing. Our (main) goals are: 1. store the filters on the database 2. allow each user to enable/disable any of the filters set we provide (it's a static set of some general filters, available to all the users; we're currently not providing the possibility to users to write their own filters) For point 1) we already see[1] that's possible, but it uses the map construct that might not fit with our current database structure: we have a domain table (storing the domain info) and a mailbox table (storing the mailbox info, but the username is composed by the local part, stored in this table, and the domain part is a FK to the domain table, using an id). Do you think it's possible to run a join query on domain+mailbox to retrieve the mailbox_id needed to query the table for the filters? Or do we have to create the filter table and store the local(a)domain.ext info there ("relaxing" the integrity relationships between tables)? How do we specify which filters are enabled for any given user? We originally thought of an "Enabled" field on the filter table, but in the example in the doc[1] I hadn't seen a way to do that: it seems like the filter list is specified in the proxy definition - am I wrong? How can we do that? [1] http://hg.rename-it.nl/dovecot-2.1-pigeonhole/file/e9ed5d5cef4b/doc/script-… I think it's enough for now, maybe additional questions will arise going deeper in details :) Thanks in advance, -- Sandro Tosi Product Engineer Shared Hosting Products R&D | Dada.pro eml sandro.tosi(a)register.it

[Dovecot] Maildir hardlinks

23 Oct '12

Hello list, Excuse me for my poor english. I have updated on a test server dovecot 2.0.13 to dovecot 2.1.1. All works fine, but with the new version it seems that dovecot don't do hardlinks when deliver a message to multiple users. I have checked my config and the only rule I can see aboout that is maildir_copy_with_hardlinks = yes in /etc/dovecot/conf.d/10-mail.conf My mail location config is mail_location = maildir:~/MailDir:LAYOUT=fs I tryed using lmtp directly issuing 'telnet localhost 24' and sending a test message to 3 recipients. Then issuing a 'ls -il' in the "new" directory of that users, I saw the inode was not the same. I rechecked my config and take a look in the wiki and in the list for someone who had the same problems, but found nothing. Maybe I did something wrong, but I can't understand what. Can you help me?

[Dovecot] index files created improperly in dovecot 1.2.16
by john roman 23 Oct '12

23 Oct '12

Greetings, It seems to be a problem that ive seen occasionally on the web with few results as to a solution, but im experiencing it as well. Namely, dovecot creates index logs for users with a 600 permission, when it should create with a 700 permission. My indexes are stored in /var/indexes with the directory at 777 permission, the users are identified in MySQL. The error is as follows: Oct 23 09:03:13 mailer01 dovecot: POP3 (johnr(a)testing.com) stat(/var/indexes/j/johnr(a)testing.com/.INBOX) failed: Permission denied (euid=10509305(x10509305) egid=81607(pg199275) missing +x perm: /var/indexes/j) the permissions of /var/indexes/j are 700, owned by the euid and egid effectively. the only file that does not have this permission is in /var/indexes/j/johnr(a)testing.com/.INBOX/dovecot.index.log, at 600.

Hello all, I would like to thank you all for your kind replies and feedback in regards to migrating from a smaller hdd to a bigger one (namely from 72gb to 146gb). I finally found a painless way of doing this. Since I believe that this is still an off-topic post, if anyone is interested in the solution i've adopted for this, let me know by replying to me privately. If, however, you don't mind me posting here, let me know. Many many thanks go to Alexander Hoogerhuis, the "mad Norwegian" :-) who helped me on this too much to describe here.

[Dovecot] (new) director issues in 2.1.10
by Kelsey Cummings 23 Oct '12

23 Oct '12

Timo - I upgraded to 2.1.10 on our director servers two nights ago and apart from errors associated with the directors processes restarting everything looked great for ~24 hours until I failed our the real servers last night to update the nfs mount options for the spools. I followed the suggested procedure for each backend server, just run on one of the directors, which seemed to work as expected. doveadm director add x.x.x.x 0 doveadm director flush x.x.x.x The following errors on the directors that started after this went unnoticed until this AM. director: User bb host lookup failed: Timeout - queued for 30 secs (Ring synced for 36 secs) director: User cc host lookup failed: Timeout - queued for 48 secs (Ring synced for 66 secs, user refreshed 12 secs ago) director: User dd host lookup failed: Timeout - queued for 124 secs (Ring synced for 119 secs, weak user, user refreshed 155 secs ago) director: User ee host lookup failed: Timeout - queued for 79 secs (Ring synced for 119 secs, weak user, user refreshed 113 secs ago) ... User ff host lookup failed: Timeout - queued for 30 secs (Ring synced for 7427 secs, weak user, user refreshed 620 secs ago) This continued, combined with occasional login timeouts (as reported by some internal imap clients.) The login delays/timeouts got bad enough that our load balancers dropped both the servers while I was investigating. They seem to be okay after being restarted. -K

[Dovecot] auth timeout state=2, bad?

[Dovecot] Marking all mail in one folder of public mailbox as read
by Frerich Raabe 22 Oct '12

22 Oct '12

Hi, I'm running Dovecot 1.2.17 on FreeBSD 9 to serve an archive of a few internal mailinglists. The archive is implemented using a public namespace: namespace private { separator = / prefix = inbox = yes } namespace public { separator = / prefix = Lists/ location = maildir:/home/vmail/lists/Maildir:CONTROL=~/Maildir/lists:INDEX=~/Maildir/lists subscriptions = no } As you can see, the CONTROL/INDEX files are stored per-user to allow private \Seen flags. The different mailinglists are all sent to the 'lists' user which has a Sieve script to file them into different folders, so I have directories on my harddisk like /home/vmail/lists/Maildir/.somelist /home/vmail/lists/Maildir/.anotherlist Now, I'd like to mark the mail in *one* of those folders as \Seen by default. If the INDEX files weren't per-user, it would simply be a matter of using 'addflag "\Seen";' in the Sieve script of the lists user. Alas, this has no effect. Hence my question - how can I have the mail of just one mailinglist get marked as "read" for all users? So far, the only option I see is to add a second public namespace, with a different prefix - and this namespace doesn't use private CONTROL/INDEX files. However, I'd like to keep using the "Lists" prefix if possible to avoid too many changes to the clients. -- Frerich Raabe - raabe(a)froglogic.com www.froglogic.com - Multi-Platform GUI Testing

The dict is also needed for quota lookup from the database. The only thing which might be omitted is the global quota_rule since it is returned by the userdb/passwd in any case, but I'm not sure what happens if you only configure a "quota_rule2" without configuring a "quota_rule". > My outstanding issue is whenever I as the root mysql user update a > user's quota the other user also gets an update, I noticed with one > the messages column on the other user went from 0 to 2, another time > the quota value went up from 0 to 3500 it seems random. You should not be accounting the actual mailbox usage in the same virtual_users table as the quota is read from. Use *different* column or table name in your dict file where dovecot may write the current storage/message count. > dovecot-dict-sql.conf.ext > > map { > pattern = priv/quota/storage > table = virtual_users > username_field = user > value_field = quota value_field should be current_quota_storage (writable column) > } > map { > pattern = priv/quota/messages > table = virtual_users > username_field = user > value_field = quota_messages value_field should be current_quota_messages (writable column) > I'd like to know why these columns are updating. Dovecot stores the current storage and mailcount in there. These columns should be different from the columns defining the maximum limit. Regards Daniel

[Dovecot] still having difficulties with per-user quotas
by David Mehler 20 Oct '12

Hello, I am trying to get per-user quotas working. My thanks to all who have helped so far. To recap I am running Dovecot 2.1 and Mysql where I've got my virtual users. All virtual users are under the system user vmail with a UID and GID of 5000. Looking over the wiki docs I've added a quota table and got the dict service working, I am not having problems with permissions or the login username and password, all that is working fine. Here's my current doveconf -n output it is producing the following debug error related to the userdb sql query: # 2.1.10: /etc/dovecot/dovecot.conf # XXX dict { quota = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } first_valid_gid = 5000 first_valid_uid = 5000 hostname = XXX last_valid_gid = 5000 last_valid_uid = 5000 mail_location = maildir:/home/vmail/%d/%n:LAYOUT=fs mail_plugins = " quota" namespace inbox { inbox = yes location = prefix = } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { quota = dict:User quota::proxy::quota quota_rule = *:storage=1G quota_rule2 = Trash:storage=+100M quota_warning = storage=95%% quota-warning 95 %u quota_warning2 = storage=80%% quota-warning 80 %u } protocols = imap service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { mode = 0600 user = vmail } } service dict { unix_listener dict { mode = 0600 user = vmail } } service imap-login { inet_listener imap { address = 127.0.0.1 ::1 } inet_listener imaps { address = xxx xxxx ssl = yes } } service quota-warning { executable = script /usr/local/bin/quota-warning.sh user = vmail } ssl_cert = </etc/ssl/certs/server.crt ssl_key = </etc/ssl/private/server.key userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } protocol imap { mail_plugins = " quota imap_quota" } Oct 19 15:23:52 auth-worker(29279): Info: mysql(/var/run/mysqld/mysqld.sock): Connected to database mail Oct 19 15:23:52 auth-worker(29279): Debug: sql(xxx,::1): query: SELECT user as user, password FROM virtual_users WHERE user='xxx@domain'; Oct 19 15:23:52 auth: Debug: client passdb out: OK 1 user=xxx Oct 19 15:23:52 auth: Debug: master in: REQUEST 3523346433 29276 1 f5cd16e3f5e078c28d850749e42c86cc Oct 19 15:23:52 auth-worker(29279): Debug: sql(xxx,::1): SELECT concat('*:storage=', bytes, 'M') as quota_rule FROM quota WHERE username='xxx'; Oct 19 15:23:52 auth: Debug: master userdb out: USER 3523346433 xxx quota_rule=*:storage=368485M Oct 19 15:23:52 imap-login: Info: Login: user=<xxx>, method=PLAIN, rip=::1, lip=::1, mpid=29282, secured, session=</xKpcW7MFgAAAAAAAAAAAAAAAAAAAAAB> Oct 19 15:23:52 imap(xxx): Error: user xxx: Couldn't drop privileges: User is missing UID (see mail_uid setting) Oct 19 15:23:52 imap(xxx): Error: Internal error occurred.

[Dovecot] Dovecot 2 and TCP-Keepalive
by Sven Hartge 20 Oct '12

20 Oct '12

Hi! I am about to migrate a perdition-based IMAP/POP3 proxy to Dovecot. Unfortunately some users are behind a firewall/NAT setup which throws away seemingly idle TCP connections sooner than the established default of 24 hours (more likely after 30 minutes ...) resulting in all kinds of weird client behavior. And unfortunately² this firewall/NAT setup is outside of my control and I have no means of correcting this (in my opinion) flawed configuration. Now, with perdition I was able to use the --tcp_keepalive option which totally solved the mentioned weird client behavior. My question is: does Dovecot2 use TCP-Keepalive on its sockets per default or do I need to enable it some way I have not yet discovered? The manual and wiki only talk about "keepalive" in connection with the IMAP protocol and IDLE and my C-fu is too weak to understand the source code. Grüße, Sven. -- Sigmentation fault. Core dumped.

Hello, Can You explain to me how dovecot-lda knows actual size of virtual user directory?

[Dovecot] Question about salted hashes
by Tobias Maffert 19 Oct '12

19 Oct '12

Hello. I'm switching from b1gmail to my own setup which consists of Postfix+Dovecot+MySQL (and maybe VBoxAdm). There are two problems: - b1gmail is using unsalted MD5 hashes. Is there any good way to make my new setup backward compatible?

[Dovecot] Add S=<size> to maildirfile

Hi, in some old Maildir/ I have file without the S=<size> in file name. Is possibile to add the size to the file name with some tools like doveadm? Are there other methods to update these file?

[Dovecot] Emails from invalid local accounts
by Steven Kiehl 19 Oct '12

19 Oct '12

Hi, I'm using dovecot 1.2.9 in a postfix/dovecot setup and I'm having issues with receiving spam where the "from" header contains an address like accounting(a)mydomain.com. Is there some way I can filter out these emails coming from outside our network with an account associated with our network which doesn't exist? Do I just need to configure some custom process to evaluate these addresses, or is there some way either in dovecot or spamassassin to do this? Thanks, Steve K

[Dovecot] lmtp proxy logging
by Jack Bates 18 Oct '12

18 Oct '12

The logging on lmtp and lmtp proxy is pretty limited from what I can see. It seems to handle errors, Connect, Disconnect, and in the case of lmtp delivery, it logs where an email is saved to. The lmtp may be enough, "connect, saved user, saved user..., disconnect", but I was curious if it is worth while to add more info logging for the proxy, primarily which recipients are sent to which proxy. I was thinking of local patching it, but I'll generate up something more inline with official code if it is desired. My thought is to show 1 entry for each recipient, and the destination server chosen. If I recall correctly, the proxy code doesn't actually listen in on the conversation, so logging results would probably complicate the code. Jack

[Dovecot] Problem with process_limit
by FABIO FERRARI 18 Oct '12

18 Oct '12

Hello, i have a problem with the process_limit configuration. Occasionally, it happens that the dovecot.log shows this line: master: Warning: service(imap): process_limit reached, client connections are being dropped So I checked, the process number, with the command: ps auxwww | grep imap | grep -v login | wc -l and it shows 1024. Then, i edited the file /etc/dovecot/conf.d/10-master.conf and set the line process_limit = 1500 I checked if the dovecot had accepted the change with the command doveconf -n | grep process_limit and it shows process_limit = 1500 But it is dropping the connections when they reach 1024 anyway, the configuration parameter is totally ignored. Can anyone help? Am I editing the right parameter? thanks in advance Fabio Ferrari P.S. The version of the dovecot is dovecot-2.0.1-1_118.el5 on Red Hat Enterprise Linux Server release 5.8 (Tikanga).

[Dovecot] real_rip variable addition for dovecot 2.1.10
by Jack Bates 18 Oct '12

18 Oct '12

Timo, Please check the code. I didn't add it, but a real_lip might be useful for some people as well. Also, I notice that pop3-proxy is doing a different xsession than the imap proxy. Is there an xsession standard that is different between the two, or just an oversight in the code? Both send the remote address/port, but only imap proxy sends the local address/port. This patch declares long variable %{real_rip} so that a backend server can declare a different login_log_format_elements login_log_format_elements = user=<%u> method=%m rip=%r lip=%l pip=%{real_rip} mpid=%e %c This is primarily useful for backend servers to log both the rip, lip, and in case of xsession, the real rip. I haven't done extensive testing yet, but as long as nothing does anything weird elsewhere in the code, it should be good. http://www.brightok.net/jbates/dovecot-2.1.10-real-ip.patch dovecot: pop3-login: Login: user=<test>, method=PLAIN, rip=192.168.1.5, lip=::1, pip=::1, mpid=8665, secured Jack Bates

[Dovecot] Difference between Indexing and Rescan in FTS
by Fred Kilbourn 18 Oct '12

18 Oct '12

I've had squat running on dovecot 2.0 and have been updating all users mailbox indexes nighty via cron with this command: doveadm -v search -A text xyzzyx I've just updated to 2.1 and I'm migrating to lucene indexes, but reading the documentation I'm having a hard time understanding the semantic differences between indexing and rescanning. If I were to continue to run an all user all mailbox index every night, would that be appropriate? Would running this every night avoid the need to ever rescan? Should I run rescan instead of index? Should I run both rescan and index? In which order? Best Regards, FredK

[Dovecot] Per user quotas
by David Travers 18 Oct '12

18 Oct '12

Hi All, I keep going round in circles with this. I have quotas up and running but would like to add a couple of per user exceptions but can't figure out how to do it! I am using Open Xchange community edition on top of dovecot and tha tis showing the 200MB limit, if I change it in the dovecot.conf the change is reflected in open xchange, but can't figure out how to change for 1 user. I believe I need to add to a passwd file, but I have added to that and nothing has changed. # dovecot -n # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-686 i686 Debian 6.0.5 log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s ssl_cert_file: /etc/ssl/certs/postfix.pem ssl_key_file: /etc/ssl/private/postfix.key login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login mail_privileged_group: mail mail_location: maildir:~/mail:LAYOUT=fs:INBOX=~/mail/ mbox_write_locks: fcntl dotlock mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 lda: mail_plugins: quota auth default: mechanisms: plain login passdb: driver: pam userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix plugin: quota: maildir:user quota quota_rule: *:storage=200M quota_rule2: Trash:storage=10%% quota_rule2: SPAM:ignore quota_warning: storage=95%% /usr/local/bin/quota-warning.sh 95 quota_warning2: storage=80%% /usr/local/bin/quota-warning.sh 80 quota_exceeded_message: Quota exceeded, Please delete some emails Any help gratefully received Dave _________________________________________ This email has been scanned for malicious content. _________________________________________

[Dovecot] Dsync clustering
by list＠airstreamcomm.net 18 Oct '12

18 Oct '12

I have not seen mention of using dsync for clustering Dovecot in some time on the mailing list, but I believe Timo was going to write a wiki page when v2.2 became more mature. Does this documentation exist yet, or are there any resources on what dsync replication is capable of at this point (looking on the wiki and google didn't reveal much)? Thank in advance.

Re: [Dovecot] Disconnected for inactivity time.

Easy enough to test. It's non-RFC compliant as one poster points out, so unless you got a good reason to do this like lots of zombie pop3 processes, leave it alone.

[Dovecot] Dovecot sieve and duplicate email subjects
by Benjamin Thomas 17 Oct '12

17 Oct '12

Hi, I'm running a small email server with the help of iRedMail. I can manage sieve scripts from the Rouncube web interface or manually inside the user's personal sieve folder. I have an email account setup to receive automated tasks. Some of these "alerts" occur too often and they have the same subject line, but different senders. This is the rule I am currently using: ##CODE START## # rule:[AutoAlerts] if anyof ( header :matches "Subject" "AutoAlert Type1*", header :matches "Subject" "AutoAlert Type2*", header :matches "Subject" "AutoAlert Type3*" ) { fileinto "INBOX.AutoAlerts"; stop; } ##CODE END## I was wondering if it's possible to gracefully handle duplicate subjects lines (within a given time frame) with sieve filters ? Ideally, I would like the first email of the day with subject ""AutoAlert Type1..." to get moved to the subfolder given above. Subsequent "duplicate" emails would then go into a "duplicate" subfolder. Is this possible with sieve filters ? I could not find anything striking me as obvious while reading the page http://wiki.dovecot.org/LDA/Sieve. Thanks very much for your input.
