[Dovecot] adding dovecot to webmin list of services
by Spyros Tsiolis 28 Oct '11

28 Oct '11

Hello , I am playing with webmin these days and find it really fun to install and use everyday. However, on the services option, amongst other services, the dovecot service is not shown. Does anyone out there have similar experience with webmin and dovecot and know how to make it appear there ? I am using CentOS (5.5/5.6/5.7) 32-bit Dovecot was installed manually and not from yum (.rpm) Dovecot v1.2.15 TIA, s. ---- "I merely function as a channel that filters music through the chaos of noise" - Vangelis

[Dovecot] IMAP shows forwarding and vacation files
by Nico Suhl 28 Oct '11

28 Oct '11

Hello, I'm migrating our mailserver from a linux machine to solaris and got some small problems with our forwarding and vacation files, which are stored in the maildir of each user. I'm now using 2.0.15, on the old machine there was a dovecot 1. Now the problem is, that the .forward and .vacation files, which are used by exim, are shown as folders (they have a point...) in imap lists. This problem only occurs on the new solaris machine and not on the old linux system (with dovecot v1) or another testing machine with dovecot 2, which runs also under linux. userdb lookups are static with system account/group of exim. Is there any way to "hide" the .forward and .vacation files or do i have to rename or move them? Why are they shown here and not on our testsystems? regards, Nico Suhl

Dovecot reports to have looked in the system password file, failed, then looked in /etc/dovecot/users and found the user and logged them in. I think the problem happens later and you will have to show the subsequent log entries. Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] Configuring mbox and maildir formats - dovecot-1.2.15
by Albert E. Whale 28 Oct '11

28 Oct '11

I am transitioning an existing server from using exclusively mbox, to being able to support both mbox and then fully maildir formats. I need to support the mbox format until I can get everyone switched over to maildir. What do I need to to use in the config of /etc/dovecot.conf to support the default of mbox, and then the new Maildir format (users will get upgraded individually from mbox to Maildir, and need to be upgraded). Thank you. -- Albert E.

[Dovecot] Marathon Day 6 of First Install: MySQL Connection Problem
by Jack Fredrikson 25 Oct '11

25 Oct '11

Hi; This is my 6th day installing my first Postfix/Dovecot installation. The Postfix mailing list indicates I've got the MTA under control so now I'm seeking your help with the MDA. I get these errors with legitimate email addresses: Oct 24 11:47:38 myserver dovecot: auth-worker: Error: mysql(localhost): Connect failed to database (postfix): Access denied for user 'dovecot'@'localhost' (using password: YES) - waiting for 25 seconds before retry Now I've logged in myself: mysql -u dovecot -p Enter password: xxx and succeeded. What am I doing wrong? I've noticed that every time I restart dovecot I get this error in the dovecot-deliver.log: Oct 24 11:31:11 lda: Error: userdb lookup: connect(/usr/local/var/run/dovecot/auth-userdb) failed: Permission denied (euid=512(vmail) egid=512(vmail) missing +r perm: /usr/local/var/run/dovecot/auth-userdb, dir owned by 0:0 mode=0755) Oct 24 11:31:11 lda: Fatal: Internal error occurred. Refer to server log for more information. Every time I go to chmod 666 on that file, restarting dovecot wipes those permissions. How fix? Even when I fix that, I still get the "temporary failure". Please advise. 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

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

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

Re: [Dovecot] "doveadm log reopen" don't reopen separate lmtp log

I still see the issue below. Is there anyone running separate LMTP logging that could check if they experience the same issue?

[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. Higher rate of success if they can mail from a known good server and account. * Simon Brereton <simon.brereton(a)buongiorno.com> [2011-10-17 11:51:15 -0400]: > On 17 October 2011 11:31, Robert Schetterer <robert(a)schetterer.org> wrote: > > Am 17.10.2011 17:16, schrieb Simon Brereton: > >> Hi > >> > >> This is a new one on me - I've never seen spammers attempt to use to SASL Auth to inject spam.

[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] 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

Even when things are filed in INBOX, the logs should show that deliver and sieve are being executed and putting the mail there. http://wiki1.dovecot.org/Logging Regards, Stephan

[Dovecot] Sieve and UserDB/SQL support
by ben＠benweblife.fr 13 Oct '11

13 Oct '11

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
