Also, I've tried to follow the advice in the warnings and it never works. I've tried the doveconf -n > dovcot-new.conf command and the same conf file I've been using pops up. Can someone post some code that reflects how the new conf file should look? TIA, Jack

[Dovecot] Don't Know Where Emails Are Or What's Happening

[Dovecot] Quota
by nuno marques 21 Oct '11

21 Oct '11

hi, I'm having some difficulty understanding the connection between postfix, dovecot and quota. What is the best way to set up quotas? through the file system quota and maildir? Need the dovecot lda working? The postfix needs a patch? I was thinking about setting quotas on file system, then configure Postfix to connect to dovecot-lda. Any suggestion? The system as a whole is composed of:dovecot-2.0-0.10.beta6.20100630.el6.x86_64 -> 2.0.beta6 (3156315704ef)openldap-servers-2.4.19-15.el6_0.2.x86_64postfix-2.6.6-2.1.el6_0.x86_64mailscanner-4.84.3-1.noarchspamassassin-3.3.1-2.el6.x86_64centos 6 2.6.32-71.29.1.el6.x86_64 #1 SMP Mon Jun 27 19:49:27 BST 2011 x86_64 x86_64 x86_64 GNU/Linux

[Dovecot] Email filters
by Jos Chrispijn 21 Oct '11

21 Oct '11

Can someone tell me how I can configure Dovecot to use message filters on incoming email? When I now activate my mail account on my mobile phone and Thunderbird (or any other mail client with message filters) is not online, I get a huge pile of email in my INBOX that I have to go thru, while 90% is not that interesting to read as they belong to Spam messages, newsletters etc. Thanks in advance Jos Chrispijn

[Dovecot] Expire plugin not executing for sieve plugin?
by Dan Swartzendruber 20 Oct '11

20 Oct '11

Running dovecot 1.2.12 on ubuntu 10.10. Here is the problem: I have mysql backend for expire. I am using the dovecot-postfix package which creates /etc/dovecot/conf.d/01-mail-stack-delivery.conf which looks like this: # Some general options protocols = imap imaps managesieve disable_plaintext_auth = no ssl = yes ssl_cert_file = /etc/ssl/certs/ssl-mail.pem ssl_key_file = /etc/ssl/private/ssl-mail.key ssl_cipher_list = ALL:!LOW:!SSLv2:ALL:!aNULL:!ADH:!eNULL:!EXP:RC4+RSA:+HIGH:+MEDIUM mail_location = maildir:~/Maildir auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@ # IMAP configuration protocol imap { mail_max_userip_connections = 10 imap_client_workarounds = outlook-idle delay-newmail mail_plugins = expire } # LDA configuration protocol lda { postmaster_address = postmaster mail_plugins = sieve expire quota_full_tempfail = yes deliver_log_format = msgid=%m: %$ rejection_reason = Your message to <%t> was automatically rejected:%n%r } # Plugins configuration plugin { sieve=~/.dovecot.sieve sieve_dir=~/sieve # If the user has no personal active script (i.e. if the file # indicated in sieve= does not exist), use this one: sieve_global_path = /var/lib/dovecot/sieve/default.sieve } The sieve is: require "fileinto"; require "imap4flags"; if header :contains "X-Spam-Flag" "YES" { setflag "\\Seen"; fileinto "SPAM"; stop; } Originally, this did not have the setflag or stop - I added them hoping to fix the problem, but no luck. The problem is this: when spam assassin has flagged a message as spam, the sieve runs and the message is in fact filed into the SPAM folder, but no expire entry is added to the database. If I move such a message from the SPAM folder to the Inbox and then back to SPAM, voila, I *do* get the entry created. Here is the mysql table before and after I did the move/move: mysql> select * from expires; +----------+---------------+--------------+ | username | mailbox | expire_stamp | +----------+---------------+--------------+ | dswartz | Deleted Items | 1319720163 | | dswartz | Sent | 1319120165 | | denise | Trash | 1319139920 | | samantha | Trash | 1319136146 | | denise | Sent | 1319655872 | | danielle | Sent | 1319192230 | | samantha | Sent | 1319268855 | | dswartz | Trash | 1319725884 | | samantha | SPAM | 1321504531 | +----------+---------------+--------------+ 9 rows in set (0.00 sec) mysql> select * from expires; +----------+---------------+--------------+ | username | mailbox | expire_stamp | +----------+---------------+--------------+ | dswartz | Deleted Items | 1319720163 | | dswartz | Sent | 1319120165 | | denise | Trash | 1319139920 | | samantha | Trash | 1319136146 | | denise | Sent | 1319655872 | | danielle | Sent | 1319192230 | | samantha | Sent | 1319268855 | | dswartz | Trash | 1319725884 | | samantha | SPAM | 1321504531 | | dswartz | SPAM | 1321714666 | +----------+---------------+--------------+ 10 rows in set (0.00 sec) It's almost like the fileinto stuff is not running the plugin code at all, or am I totally on drugs? If I can't get a fix for this, I at least now can think of a hack to "fix" it. e.g. every night, run a script that adds a "now" timestamp for everyone's SPAM folder to trick the periodic expire tool code into checking that folder, but obviously I'd rather have a real fix :) If this is just 'how it works', is it better in 2.0?

[Dovecot] too many open files and v1.2
by Michael Moritz 20 Oct '11

20 Oct '11

Hi I've found an older thread http://www.dovecot.org/list/dovecot/2010-March/047886.html which mentions that this is a bug in version 1. I'm on Debian squeeze (1:1.2.15-7) and got errors like these recently Oct 5 11:29:29 mail dovecot: dovecot: pipe() failed: Too many open files Oct 5 11:29:32 mail dovecot: dovecot: pipe() failed: Too many open files Oct 5 11:29:32 mail dovecot: dovecot: Temporary failure in creating login processes, slowing down for now As a work around I've increased login_max_processes_count from 256 to 512 and it seems to have helped (as I suspected stale opened files). My colleague thinks it's hitting the kernel open file limit ulimit -n (currently at 1024) but I don't see how that could happen if the number of process is nowhere near that. Any ideas? Thanks, Michael

[Dovecot] Is '*:bytes=" quota specification the quota 'Value', or 'Limit'?
by Rich 19 Oct '11

19 Oct '11

Docs for quota configuration http://wiki2.dovecot.org/Quota/Configuration#Limit_configuration state that the 'bytes=' specification defines the quota **LIMIT** "bytes: Quota limit in bytes, 0 means unlimited" as used in plugin { ... quota_rule = *:bytes=10000000 ... BUT, documentation for quota dict http://wiki2.dovecot.org/Quota/Dict states "MySQL uses the following queries to update the quota" and provides an SQL example of Dovecot decrementing the 'bytes' value, "UPDATE table SET bytes=bytes-14433,messages=messages-2 ..." I'm working on a current problem (http://dovecot.org/list/dovecot/2011-October/061538.html) with 'doveadm' reporting mixing up quote Value & Limit. Question: Is 'bytes' supposed to contain the Value, or the Limit? Rich

Hi, I'm setting up SQL quota usage in Dovecot2. I've created a MAILBOX parameter table, 'PARAMS', that contains unique <user>@<domain> pairs, with quota data. mysql> select * from PARAMS; +----+------------------------+------------+-------------+------------+ | ai | MAILBOX_user_domain | quota | quota_bytes | quota_msgs | +----+------------------------+------------+-------------+------------+ | 1 | myuser(a)domain1.com | 1073741824 | 0 | 0 | | 2 | myuser(a)domain2.com | 1000000000 | 0 | 0 | +----+------------------------+------------+-------------+------------+ 2 rows in set (0.00 sec) I've specified dict usage for quota, /etc/dovecot/dovecot.conf !include conf.d/*.conf protocols = imap lmtp dict { quota = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } created the maps, /etc/dovecot/dovecot-dict-sql.conf.ext connect = host=/var/run/mysql/mysql.sock dbname=my_db user=my_user password=my_pass map { pattern = priv/quota/storage table = PARAMS username_field = MAILBOX_user_domain value_field = quota_bytes } map { pattern = priv/quota/messages table = PARAMS username_field = MAILBOX_user_domain value_field = quota_msgs } assigned the global values and backend, /etc/dovecot/conf.d/90-quota.conf plugin { quota = dict:User Quota::proxy::quota quota_rule = *:storage=1GB:messages=10000 quota_rule2 = Trash:storage=+10%% } and specified the user iteration query /etc/dovecot/sql/virtmail-userdb-sql.cf driver = mysql connect = host=/var/run/mysql/mysql.sock dbname=my_db user=my_user password=my_pass user_query = CALL UserDBQuery('%n','%d'); iterate_query = SELECT `MAILBOX_user_domain` AS user FROM `PARAMS`; Verifying operation with with `doveadm`, I get a result from a !error query, doveadm quota get -u myuser(a)domain1.com Quota name Type Value Limit % User quota STORAGE 0 1048576 0 User quota MESSAGE 0 10000 0 doveadm quota get -u myuser(a)domain2.com Quota name Type Value Limit % User quota STORAGE 0 1048576 0 User quota MESSAGE 0 10000 0 But notice that there's no specificity by *domain*. Despite being provided the full <user>@<domain>, matched to the map, username_field = MAILBOX_user_domain the Dovecot dict query seems to ignore the <domain> part, and simply matches on the first of the tow identical <user> parts. Specifying "-A" doesn't help, doveadm quota get -A Username Quota name Type Value Limit % myuser(a)domain1.com User quota STORAGE 0 1048576 0 myuser(a)domain1.com User quota MESSAGE 0 10000 0 myuser(a)domain2.com User quota STORAGE 0 1048576 0 myuser(a)domain2.com User quota MESSAGE 0 10000 0 What needs to be done to get domain-specificity in the 'doveadm quota get' query? Is my configuration off, or incomplete, or is this a bug? Thanks, Rich

[Dovecot] LDA/Postfix with quotas and without LMTP
by Steve Fatula 18 Oct '11

18 Oct '11

Reading the wiki page for dovecot2 and LDA/Postfix, the system users section (all mail delivery goes to system users)... It shows you can simply use postfix mailbox_command. There is this additional comment: "This command doesn't do a userdb lookup. If you want that (e.g. for per-user quota lookups) you need to add -d "$USER" parameter." So, i added that. Once adding it, I find I get an error: dovecot: lda: Error: userdb lookup: connect(/var/run/dovecot/auth-userdb) failed: Permission denied Using mailbox_command in Postfix means that dovecot-lda is running as the system user getting the mail. Which means it can't access the socket file. Of course, one can simply use mode 666 on it, but, then people can use it to find out information according to the doc, which I do not want. So, I am not sure why the doc says to add -d for per user quotas, without also mentioning the problem with doing that. I don't see how it can work? Assuming I need per user quotas, and I don't want to use LMTP, is there a good way around this without the security issue? Steve

[Dovecot] Syntax to specify sdbox: mail_location path?
by mephistopheles＠operamail.com 18 Oct '11

18 Oct '11

I'm implementing sdbox. In conf.d/10-mail.conf, with "maildir:" mail_location = maildir:/my_mailbox_path/%d/%n mail gets stored in /my_mailbox_path/%d/%n/new/ With "sdbox:" mail_location = sdbox:/my_mailbox_path/%d/%n mail gets stored in /my_mailbox_path/%d/%n/mailboxes/INBOX/dbox-Mails. How do I get rid of the '/mailboxes/' and '/dbox-Mails/' path components so sdbox stores in: /my_mailbox_path/%d/%n/INBOX @ wiki2.dovecot.org/MailboxFormat/dbox#Alternate_storage points out that 'ALT=' can change the *lookup* location, and messages can be *moved* to ALT storage using 'doveadm altmove'. Unclear what TAGS are available/used for 'sdbox'.

[Dovecot] Rare error with concurrent users searching with fts-solr
by Antonio Perez-Aranda 18 Oct '11

18 Oct '11

Hi all, If I start two o more connections with diferent users that make a search text to solr I get this message many times: Error: fts_solr: Query didn't return uid If I repeat the test about 2000 times, with only one user concurrent, with 60 diferent users, without concurrent, I get between 0. If I repeat the test about 2000 times, with 2 users concurrent, I get between 3 or 10 errors. If I repeat the test about 2000 times, with 4 users concurrent, I get between 10-20 errors. After see this error, I set a tcpdump to try to watch the SOLR XML and GET, I can watch that Solr send a xml like this: <response></response> with 200 as http status When the normal response is like this <response> <lst name="responseHeader"> <int name="status">0</int> <int name="QTime">1</int> <lst name="params"> <str name="fl">uid,score</str> <str name="sort">uid asc</str> <str name="q">BLABLABLA</str> <str name="fq">+user:"ANYUSER" +uidv:1208469916 +box:"ANYFOLDER" -ns:[* TO *]</str> <str name="rows">1</str> </lst> </lst> <result name="response" numFound="0" start="0" maxScore="0.0"/> </response> At first, I think that the problems it's in Solr, but after get all GET from tcpdump, I make a python script with urllib2 and send it all to Solr with the same concurrency and I can't get any error or "empty response" Have someone made a intensive concurrency tests over Dovecot + Solr ? -- Antonio Pérez-Aranda Alcaide aperezaranda(a)yaco.es Yaco Sistemas S.L. http://www.yaco.es/ C/ Rioja 5, 41001 Sevilla Teléfono +34 954 50 00 57 Fax +34 954 50 09 29

[Dovecot] 2.1 Plans
by Steve Fatula 18 Oct '11

18 Oct '11

Back in early 2010, Timo posted about a potential 2.1 feature to in essence reduce the number of imap/pop3 processes using various techniques since the code already supports multiple connections. It even went as far as moving all idle connections. I don't see this on the 2.1 roadmap. Is it still planned perhaps for 2.1? Thousands of imap processes going away is a great thing for me! So, just curious. Reference: http://dovecot.org/list/dovecot/2010-January/046148.html Steve

[Dovecot] doveadm mailbox list shows file system directories as mailboxes

Hello. In our dovecvot we use mbox format with the default filesystem layout. Therefore it is not possible to have mailboxes which are subfolders of other mailboxes containing messages. The command "doveadm mailbox list" includes the file system directories, that contain only subfolders, as normal mailboxes in the output: archiv archiv/daemon archiv/dovecot Did I miss something in the dovecot configuration or is there a bug in the command "doveadm mailbox list"? # 2.0.13: /opt/local/etc/dovecot/dovecot.conf # OS: SunOS 5.10 sun4v auth_verbose = yes disable_plaintext_auth = no listen = imap.hrz.uni-giessen.de localhost mail_fsync = always mail_location = mbox:~/Mail:INBOX=/var/mail/%u mail_nfs_index = yes mail_nfs_storage = yes mail_plugins = mail_log notify managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date mmap_disable = yes namespace { inbox = yes location = prefix = separator = / type = private } namespace { hidden = yes list = no location = prefix = Mail/ separator = / subscriptions = yes type = private } Thanks, Jürgen -- Hochschulrechenzentrum der | Mail: Juergen.Obermann(a)hrz.uni-giessen.de Justus-Liebig-Universitaet | WWW: http://www.uni-giessen.de/obermann/ Heinrich-Buff-Ring 44 | Tel: 0641-99-13054 (0641-99-13001) D-35392 Giessen, Germany | Fax: 0641-99-13009

Re: [Dovecot] Spammers attempting SASL Auth

Take a look at: http://hg.dovecot.org/dovecot-2.0/file/962df5d9413a/src/auth/auth-request.c on line 536. That's the auth service catching illegal characters and rejecting the attempt. It'll happen with or without a valid user. So, working as it should. As for spammers trying to brute force valid logins, yep, pretty common.

Dovecot2 has been around for a bit now but Eugene Paskevich's antispam plugin unfortunately still doesn't seem to have a tagged release. Has anyone by any chance rolled a .deb for the plugin that works on current Debian sid? -- Philipp Haselwarter

[Dovecot] lmtp performance
by Juan Carlos Sanchez 17 Oct '11

17 Oct '11

Hello: In the process of migration from version 1.2 to 2.0 have tried to use lmtp instead of lda as delivery agent. But unfortunately througput we get is poor with lmtp compared to lda. In peak times with lda we are able to deliver over 1800 messages/minute (high I/O but not affecting service) but if we switch to lmtp cannot deliver more than 300 mess/minute (very low I/O). This is enough for normal work but low under heavy load (distribution lists messages sometimes stay queued for 4 hours before deliver). We have arround 50000 boxes and use postfix as MTA How to increase lmtp performance? dovecot config for lda and lmtp: protocol lda { auth_socket_path = /usr/local/var/run/dovecot/auth-master info_log_path = /var/log/mail/dovecot_deliver.log log_path = /var/log/mail/dovecot_deliver.log mail_plugins = quota sieve zlib postmaster_address = postmaster(a)upm.es sendmail_path = /usr/lib/sendmail } protocol lmtp { info_log_path = /var/log/mail/dovecot_deliver.log log_path = /var/log/mail/dovecot_deliver.log mail_plugins = quota sieve zlib postmaster_address = postmaster(a)upm.es sendmail_path = /usr/lib/sendmail } In postfix I have: mailbox_transport = lmtp:unix:private/dovecot-lmtp Thanks in advance. -- ------------------------------------------------------ Juan Carlos Sanchez Hernandez Universidad Politecnica de Madrid ------------------------------------------------------

[Dovecot] Problems Configuring Pigeonhole/Seve
by Ian Barton 17 Oct '11

I am moving my email server from Ubuntu Lucid to Arch. The Arch server is running Dovecot V2.0.15. Email is working fine, but I can't get Pigeonhiole/sieve to work. My dovecot.conf is: protocols = imap sieve ssl = yes ssl_cert = </etc/ssl/certs/mail2.wilkesley.net.crt ssl_key = </etc/ssl/private/mail2.wilkesley.net.key first_valid_uid = 5000 first_valid_gid = 5000 auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@ namespace { location = maildir:/home/vmail/%d/%n/Maildir type = private prefix = INBOX. inbox = yes hidden = yes } protocol imap { imap_client_workarounds = delay-newmail tb-extra-mailbox-sep } protocol lda { postmaster_address = ian(a)wilkesley.net hostname = wilkesley.org sendmail_path = /usr/sbin/sendmail mail_plugins = $mail_plugins sieve } protocol sieve { # Nothing to do here as defaults are OK } plugin { sieve = ~/.dovecot.sieve sieve_global_path = /home/vmail/globalsieverc sieve_dir = ~/ } passdb { driver = sql args = /etc/dovecot/dovecot-sql.conf } userdb { driver = sql args = /etc/dovecot/dovecot-sql.conf } I have created the sieve dir in the virtual users folder. However sieve doesn't appear to be working. I have tried logging in manually to see if sieve is running, but get the following error: ian:~/ $ gnutls-cli --starttls -p 143 mail2.wilkesley.net [8:32:22] Resolving 'mail2.wilkesley.net'...

According to the Dovecot wiki this should reply with the capabilities of my server, Note the server sends and receives mail OK using starttls. So what am I doing wrong?

[Dovecot] Question about ionice & dovecot-deliver
by Maria Arrea 16 Oct '11

16 Oct '11

Hello We are running dovecot 2.0.13 with mdbox on RHEL 5.7 x64, ext4 filesystem. Sometimes we have a big load increase because a mailing list server send 16.000 32k messages in less than 3 minutes. We want to "slow down" delivery, we prefer slow delivery instead of logging out webmail users. I have the following line en /etc/postfix/master.cf: flags=DRhu user=userid argv=/usr/libexec/dovecot/deliver -d ${user} And in /etc/postfix/main.cf mailbox_command = /usr/libexec/dovecot/deliver I would like to add ionice to the equation, prefixing /usr/bin/ionice -c2 -n6 before the deliver lines in postfix config. Is there any other way of slowing down delivery speed vs imap access? Regards Maria

Hi, I would like to know if plugins of sieve support UserDB/SQL backend. For example, for the vacation plugin, is it possible to retrieve a field like "sieve_vacation_days", "sieve_vacation_reason", and so on.. on user_query? Or, there is a plan for implement this? Thanks ------ dovecot version: 2.0.13

[Dovecot] Dovecot not processing through Sieve
by Steven Kiehl 13 Oct '11

13 Oct '11

Hello everyone, I'm fairly new to Dovecot, but I've gotten the majority of things working except for Sieve. I'm running Dovecot 1.2.9 coupled with Postfix and SpamAssassin all with a virtual domains setup. I am receiving mail and it is being processed by all the plugins that operate through Postfix. The quota configured in Dovecot appears to be working because my mail client shows the configured quota. But the Sieve rules are not processing. I created a rule as follows to filter spam: require ["fileinto"]; # rule:[global-spam] if anyof (header :contains "Subject" "[SPAM]", header :contains "X-Spam-Flag" "YES") { fileinto "Junk"; } If I mail myself a message with [SPAM] in the title, it goes into my inbox regardless. I've run 'sieve-test' with the same email and it says it will file it into Junk. The Junk folder exists. I even tried adding :create and the "mailbox" plugin, but that didn't do anything either. Here is the relevant majority of my dovecot configuration: 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 login_executable(managesieve): /usr/lib/dovecot/managesieve-login mail_privileged_group: mail mail_location: maildir:/home/dovecot/mail/domains/%d/%n/Maildir mail_debug: yes 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_executable(managesieve): /usr/lib/dovecot/managesieve mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota mail_plugins(managesieve): 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 mail_plugin_dir(managesieve): /usr/lib/dovecot/modules/managesieve imap_client_workarounds(default): outlook-idle delay-newmail tb-extra-mailbox-sep imap_client_workarounds(imap): outlook-idle delay-newmail tb-extra-mailbox-sep imap_client_workarounds(pop3): imap_client_workarounds(managesieve): pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh pop3_client_workarounds(managesieve): namespace: type: private separator: / inbox: yes list: yes subscriptions: yes lda: *mail_plugins: quota sieve* quota_full_tempfail: yes deliver_log_format: msgid=%m: %$ rejection_reason: Your message to <%t> was automatically rejected:%n%r auth default: mechanisms: cram-md5 plain login passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: sql args: /etc/dovecot/dovecot-sql.conf socket: type: listen master: path: /var/run/dovecot/auth-master mode: 384 user: dovemail group: dovemail socket: type: listen client: path: /var/spool/postfix/private/dovecot-auth mode: 432 user: postfix group: postfix plugin: convert_mail: maildir:/home/dovecot/mail/domains/%d/%u/Maildir * sieve: /etc/dovecot/sieve/domains/%d/%n.sieve* * sieve_global_dir: /etc/dovecot/sieve/global/* quota: maildir:User quota_rule: INBOX:storage=500M quota_rule2: INBOX.Trash:storage=100M The sieve plugin exists in /usr/lib/dovecot/modules/lda/lib90_sieve_plugin.so, so I would assume I'd have to use *mail_plugin: sieve* as my configuration setting. Like I said, I am receiving emails to my domains without any problem, but sieve rules are not being processed. I can see the rules set up by using the Roundcube plugin, and I can create and edit rules through Roundcube, but nothing different happens when I send myself an email. It all just delivers to the inbox. Thanks for your help, Steve K.

[Dovecot] Auth Worker failures
by Simon Brereton 12 Oct '11

12 Oct '11

Hi I have a script that checks the logs each day and mails me invalid user attempts and authentication failures for the previous day. (I use fail2ban to ban multiple attempts in a short space of time). For some reason, this appears every day: Oct 11 06:25:12 mail dovecot: auth-worker(default): sql(simon(a)mydomain.net,127.0.0.1): Password mismatch Oct 11 06:25:19 mail dovecot: auth-worker(default): sql(simon(a)mydomain.net,127.0.0.1): Password mismatch Oct 11 06:25:31 mail dovecot: auth-worker(default): sql(simon(a)mydomain.net,127.0.0.1): Password mismatch Oct 11 06:25:48 mail dovecot: auth-worker(default): sql(simon(a)mydomain.net,127.0.0.1): Password mismatch Oct 11 06:26:10 mail dovecot: imap-login: Aborted login (auth failed, 4 attempts): user=<simon(a)mydomain.net>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Of all the accounts on the box, it's only mine that throws this up. Since its LIP is localhost, it could really only be for webmail - but I don't always leave the webmail open, so I'm curious to know how this gets there and what it is. Any suggestions? I find it difficult to believe I have an IMAP process in a script somewhere (especially with my user account - the postmaster account, I could believe, but not with my personal one).. The log time is UTC, so watching the process list at 2.24 is less than appealing! Simon

[Dovecot] To query two SQL tables for user verification over LMTP, should I use (a) two separate lookups? or (b) just one lookup with a boolean query?
by jake0534＠airpost.net 12 Oct '11

12 Oct '11

Hey all I've been running a Dovecot 1X server for awhile. Most of the config was pretty simple using flat files. I'm switching to Dovecot 2X now, and want to switch to using SQL for lookups so I can share info with the Postfix front end. For starters I setup two SIMPLE SQL tables -- a 'users' table and a 'aliases' table, where each user can have many aliases. I want to have Postfix check Dovecot's SASL/LMTP passdb to see if a <user>@<domain> exists. If yes, deliver through LMTP. If NO, reject it. Here are the table definitions so far, CREATE TABLE user ( userid TINYINT, user VARCHAR(64), domain VARCHAR(128), password VARCHAR(64), PRIMARY KEY (userid), UNIQUE (user,domain) ); CREATE TABLE alias ( aliasid TINYINT, alias VARCHAR(64), user VARCHAR(64), domain VARCHAR(128), PRIMARY KEY (aliasid), UNIQUE (domain,user,alias), CONSTRAINT fk_alias1 FOREIGN KEY (user) REFERENCES user (user) ON DELETE NO ACTION ON UPDATE NO ACTION, CONSTRAINT fk_alias2 FOREIGN KEY (domain) REFERENCES user (domain) ON DELETE NO ACTION ON UPDATE NO ACTION ); With flat file and just one table, 'users', I get how to setup LMTP. I can get Postfix delivering/rejecting over LMTP depending on if the user exists in the Dovecot passdb or not. I don't get how to do the SQL query in Dovecot if I have the TWO tables. An inbound <user>@<domain> needs to be auth'd as valid if it exists in EITHER 'user' OR 'alias' table. Do I need to use a single lookup for passdb with some sort of "IF EXISTS IN TABLE 'user' OR TABLE 'alias'" query? Or do I need to have TWO lookups, the main one for 'user' and a fallback one for 'alias' (like talked about here http://wiki2.dovecot.org/Authentication/MultipleDatabases)? Cheers! Jake

[Dovecot] inbox issue
by Eric Broch 10 Oct '11

10 Oct '11

I have dovecot 2.0.11 installed on a CentOS 5.7 email server. Two of the server email clients, one using Outlook and the other Thunderbird, have had all the contents of their inbox disappear only to reappear at a later time. One client's inbox email reappeared upon receiving a test email (to check if it would show up in the inbox) from another user. Has anyone heard of such a thing? Here's a dump of my dovecot configuration. # 2.0.11: /etc/dovecot/dovecot.conf # OS: Linux 2.6.18-238.19.1.el5 i686 CentOS release 5.7 (Final) auth_anonymous_username = anonymous

Re: [Dovecot] Filesystem quotas
by Joseph Tam 10 Oct '11

10 Oct '11

Timo Sirainen writes in response to Steve Fatula's query: > With imap_quota plugin it allows IMAP client to see how much quota is > used/left. You could also enable quota warnings. And configure the > quota exceeded error message. It could also prevent the catch-22 situation I wrote about earlier whereby a filesystem out-of-space condition will result in a user not being able get themselves out of that situation, since a mailbox operation (like a delete and expunge) will not be able to create a lockfile. Having quotas handled by the IMAP/LDA will allow extra room to handle this impasse. Disabling dotlock or using dotlock_try locking method are some other workarounds.

[Dovecot] Filesystem quotas
by Steve Fatula 10 Oct '11

10 Oct '11

I am wondering if I really need to use dovecot quota functions or not. Assume for the moment, that, each system user has a quota defined using Linux quotas, and that the Maildir is within their quota limited directory. So, any mail (or files created by the user etc) that would exceed the quota obviously can't be created. In such an environment, is there any advantage to implementing the same quota already defined in the filesystem via dovecot? Or, can I just make things simpler and ignore dovecot quotas? Assuming I keep the index and control files out of the quota limited directories. I presume if exceeding filesystem quota, the mail will not be delivered of course. If using lmtp, I presume it stays in the queue to retry later for some period of time. Steve

[Dovecot] lazy expunge namespaces
by Micah Anderson 07 Oct '11

07 Oct '11

I turned on lazy_expunge and configured a namespace following the wiki[0] instructions for mdbox configuration: namespace { inbox = yes location = prefix = separator = . } namespace { hidden = yes inbox = no list = no location = prefix = INBOX. separator = . } namespace { location = mdbox:~/mdbox:MAILBOXDIR=expunged prefix = EXPUNGED. separator = . } This created an EXPUNGED mailbox in my client (thunderbird), which was greyed out. When I deleted things, they got put in the EXPUNGED mailbox, as expected, but I could not access them to try and "restore" them. The server would say that the mailbox did not exist. micah 0. http://wiki2.dovecot.org/Plugins/Lazyexpunge --

[Dovecot] doveadm mailbox subscribe wildcard
by Micah Anderson 07 Oct '11

07 Oct '11

Hi, I noticed that wildcards work like the following, as described in the man page: # doveadm mailbox list -s -u bob dovecot* dovecot dovecot/pigeonhole dovecot/pigeonhole/2.0 however, wildcard subscriptions don't work: # doveadm mailbox subscribe -u bob dovecot* # doveadm mailbox list -s -u bob dovecot* dovecot dovecot* dovecot/pigeonhole dovecot/pigeonhole/2.0 It seems I subscribed the non-existant mailbox called 'dovecot*' -- is there a better way to handle this? thanks! micah --
