[Dovecot] Pigeonhole sieve include namespace regression
by Daniel Piddock 07 Aug '12

07 Aug '12

Hi, We've recently upgraded from Dovecot 1.2.15 with Sieve 0.1.18 (Debian Squeeze) to Dovecot 2.1.8 and Pigeonhole 0.3.1. We provide a selection of global sieve scripts to make users' lives easier and one noticed that some of these have stopped working. I tracked it down to them having personal scripts with the same name. Using a really simple sieve script: require "include"; include :personal "svn"; include :global "svn"; sievec debug output for sieve 0.1.18 (trimmed a bit): * Required extensions: 0: include (16) 1: fileinto (5) * Included personal script 'svn' (block: 3): [script code here] * Included global script 'svn' (block: 4): [script code here] * Main program (block: 1): 00000000: EXTENSIONS [1]: 00000001: include 00000002: INCLUDE: 00000004: script: svn.sieve [ID: 1, BLOCK: 3] 00000006: INCLUDE: 00000008: script: svn.sieve [ID: 2, BLOCK: 4] 0000000a: [End of code] sievec debug output for Pigeonhole 0.3.1: * Required extensions (block: 1): 0: include (id: 16; block: 4) 1: fileinto (id: 5) * Included personal script 'svn' (block: 5): [script code here] * Main program (block: 2): Address Line Code 00000000: DEBUG BLOCK: 3 00000001: EXTENSIONS [1]: 00000002: include 00000003: 2: INCLUDE: 00000005: script: `svn' from /home/notroot/sieve/svn.sieve [ID: 1, BLOCK: 5] 00000007: 3: INCLUDE: 00000009: script: `svn' from /home/notroot/sieve/svn.sieve [ID: 1, BLOCK: 5] 0000000b: 3: [End of code] As can be seen the personal script is included twice. Obvious work around is to rename the personal script. However it'd be nice if namespacing came back.

[Dovecot] connectionlimit for pop3s?
by Hajo Locke 07 Aug '12

07 Aug '12

Hello, i have a user who is able to do pop3 on port 110 without problems and without limits. There are ~10 real users using same public IP. When switching to port 995 to use pop3s he is limited at connection count. Some people can reach pop3s-server successful, some getting a timeout. I cant find any errors or limits within my config or in my log, there are no differences between using plain text and using tls. Are there some special loglines to grep for at this situation? Maybe i missed some lines... At the moment i dont see server-side problems. Somebody knows some typical clientside problems when this problem occurs? dovecot version is 1.2.11 Thanks, Hajo

[Dovecot] LDAP auth with AD

Hi, I'm struggling to setup LDAP authentication with dovecot against an AD server.

[Dovecot] redirect actions exceeds policy limit
by Mike Greene 06 Aug '12

06 Aug '12

Hello, We have a vacation/mail forwarder plugin in squirrel mail that allows customers to forward email. It has come to my attention that there is a limit (appears to be 5) on the number of addresses that can be specified. I'm now trying to track down where this policy limit is set. This is the error we see in the customers .dovecot.sieve.log file: main_script: line 26: error: number of redirect actions exceeds policy limit. sieve: info: started log at Jul 25 07:02:54. I checked the following for possible settings: /usr/local/etc/dovecot/dovecot.conf /usr/local/etc/sieve/dovecot.sieve /usr/local/etc/sieve/global.sieve I didn't see anything specific to limiting the number of redirects. I'm wondering where else I can look to find where this limit is coming from and adjust it upwards. We are using the following dovecot / pigeonhole versions. dovecot-2.0.7 dovecot-pigeonhole-0.2.1 athena# dovecot -n # 2.0.7: /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 8.1-RELEASE amd64 auth_default_realm = rockisland.com auth_mechanisms = plain login cram-md5 auth_username_format = %Lu disable_plaintext_auth = no dotlock_use_excl = yes first_valid_gid = 1000 first_valid_uid = 1000 listen = * mail_location = mbox:~/mail:INBOX=/var/mail/%u mail_privileged_group = mail 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 passdb { args = /usr/local/etc/dovecot/dovecot-ldap.conf driver = ldap } plugin { quota = maildir quota_rule = *:storage=2G quota_warning = storage=90%% /usr/local/sbin/quota-warning.sh 90 quota_warning2 = storage=80%% /usr/local/sbin/quota-warning.sh 80 sieve = ~/.dovecot.sieve sieve_dir = ~/ sieve_global_dir = /usr/local/etc/sieve/ } protocols = imap pop3 service auth { unix_listener auth-client { mode = 0660 } unix_listener auth-master { group = vmail mode = 0600 user = vmail } unix_listener auth-userdb { group = vmail mode = 0600 user = vmail } user = root } service imap-login { service_count = 0 } service pop3-login { service_count = 0 } ssl_cert = </usr/local/etc/ssl/star.rockisland.com.crt.pem ssl_key = </usr/local/etc/ssl/star.rockisland.com.key.pem userdb { driver = prefetch } userdb { args = /usr/local/etc/dovecot/dovecot-ldap.conf driver = ldap } verbose_proctitle = yes protocol imap { imap_client_workarounds = delay-newmail tb-extra-mailbox-sep mail_plugins = quota imap_quota } protocol pop3 { mail_plugins = quota pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_uidl_format = %08Xu%08Xv } protocol lda { auth_socket_path = /var/run/dovecot/auth-master info_log_path = lda_mailbox_autocreate = no lda_mailbox_autosubscribe = yes log_path = mail_plugins = quota sieve postmaster_address = postmaster(a)rockisland.com sendmail_path = /usr/sbin/sendmail } Mike Greene Rock Island Technology Solutions, Inc.

I'm trying to setup per user '+spam' delivery from amavis tags, so that each user gets any mails tagged as spam to 'spam' Maildir via +spam Dovecot lmtp delivery. after say 7 days I want to delete all spams older than 7 days, if I simply delete mail files from the file system, is that a 'bad thing' ? what is a proper way to do that, and scripts ? for removing/archiving old uncollected emails in main INBOX I use archivemail from sf, but, don't think I can do subfoldrs with archivemail any pointers (and scripts) welcomed, thanks -- Voytek

[Dovecot] authenticate plain and utf-8 with special chars
by Matthias Lay 04 Aug '12

04 Aug '12

Hi, I experienced some problems with authenticate. seems like the mail clients like thunderbird send their base64 string in ISO- encoding, which doesnt work on my dovecot setup if there are some Umlauts I am not able to login as "ömer" for example If I authenticate from telnet with an base64 encoded utf-8 string like 'echo -en "\0ömer\0Start12" |base64' everything works fine -dovecot 2.1.7 -userdb is an openldap which queries an windows AD so results are in utf8, I think. any clues at which point to fix this are welcome ;)

[Dovecot] Overriding inbox= in userdb extra fields
by Bret Martin 03 Aug '12

03 Aug '12

Hello, I'm trying to set up an alternate user with a different inbox using passwd-file and userdb extra fields and the extra field settings don't seem to be taking effect. I've used auth_debug and mail_debug and I'm unclear how I can further troubleshoot this. Is it possible to have inbox=yes in one namespace globally and then override this for one user by setting inbox=no for that namespace and then inbox=yes for another? My doveconf -n is below. I would like to have inbox=yes for the inbox namespace, inbox=no for the virtual namespace, and then be able to invert these for selected users using userdb extra fields. My attempt at doing this so far looks like bam-ios:[REDACTED]:500:500::/home/bam::user=bam namespace/inbox/inbox=no namespace/virtual/inbox=yes Changing the user with user= seems to work fine, but the inbox= changes don't.

[Dovecot] v2.1.9 released
by Timo Sirainen 03 Aug '12

03 Aug '12

http://dovecot.org/releases/2.1/dovecot-2.1.9.tar.gz http://dovecot.org/releases/2.1/dovecot-2.1.9.tar.gz.sig I've again mostly finished reading and answering most of the mails in Dovecot mailing list. There are a couple annoyingly difficult / time consuming bugreport mails that I haven't replied to yet, but if anyone thinks I should have replied to something already feel free to resend the mail. For the new Redis/memcached dict stuff see http://master.wiki2.dovecot.org/AuthDatabase/Dict and http://master.wiki2.dovecot.org/Quota/Dict I'm thinking about removing the new quota_ignore_save_errors=yes setting in v2.2 and just forcing it enabled always. Thoughts? (I didn't want to change v2.1 behavior by doing this.) The most important changes since v2.1.8: * mail-log plugin: Log mailbox names with UTF-8 everywhere (instead of mUTF-7 in some places and UTF-8 in other places) * director: Changed director_username_hash setting's default from %u to %Lu (= lowercase usernames). This doesn't break any existing installations, but might fix some of them. + doveadm: Added "auth cache flush [<username>]" command. + Implemented dict passdb/userdb + Implemented Redis and memcached dict backends, which can be used as auth backends. Redis can also be used as dict-quota backend. + Added plugin { quota_ignore_save_errors=yes } setting to allow saving a mail when quota lookup fails with temporary failure. - Full text search indexing might have failed for some messages, always causing indexer-worker process to run out of memory. - fts-lucene: Fixed handling SEARCH HEADER FROM/TO/SUBJECT/CC/BCC when the header wasn't lowercased. - fts-squat: Fixed crash when searching a virtual mailbox. - pop3: Fixed assert crash when doing UIDL on empty mailbox on some setups. - auth: GSSAPI RFC compliancy and error handling fixes. - Various fixes related to handling shared namespaces

[Dovecot] Antispam only when LMTP delivers some specific messages
by Sandro Tosi 03 Aug '12

03 Aug '12

Hello, we're setting up a weird platform where every incoming email is passed from the MTA directly to a tool that then uses dovecot LMTP to deliver the message into the user mailbox. We are legally *not* allowed to run antispam on all the incoming messages, but only on some of them, as they are recognized by the aforementioned tool; but given that tool directly uses LMTP to delivers the mail we need to find a way to parse the messages passing thru LMTP and run spamassassin only on those matching some regex on subject and mail body. Is is possible to do that with some dovecot LMTP feature? i've read a lot of documentation about how to possibly implement it and it *seems* there would be a way using pigeonhole sieve and extprograms - what do you think? The idea I have in mind is something like: 1. identify the mails we want to scan with spamassassin (using regex or whatever else to precisely pin-point them) 2. run SA on those 3. in case it's spam, rewrite the subject (or similar) Do you think it's something doable with dovecot? Thanks in advance, -- Sandro Tosi Product Engineer Shared Hosting Products R&D | Dada.pro eml sandro.tosi(a)register.it

What whould be the best way to do this, maybe in plugins/quota/quota.c:quota_root_add_rules() ? Regards, Michal Grzedzicki

[Dovecot] Problem with preserving MIME format with Dovecot IMAP and MS Outlook client
by Peter Grimmond 01 Aug '12

01 Aug '12

Hello all, Apologies for the repost, but I am really struggling to solve this problem... I have installed Dovecot 2.0.19 on Ubuntu 12.04 LTS. I have set up a very basic IMAP configuration. I have two different laptops running MS Outlook (one MacOS, one Windows 7) and I have configured both to connect to the Dovecot service. My problem is, emails in MIME format that I synchronise from one MS Outlook client are not being correctly decoded as MIME messages on the other client. Instead, the message is rendered in plaintext, starting with the lines: This message is in MIME format. Since your mail reader does not understand this format, some or all of this message may not be legible. --B_3426360453_22814Content-type: multipart/alternative; boundary="B_3426360453_4099" --B_3426360453_4099Content-type: text/plain; charset="ISO-8859-1"Content-transfer-encoding: quoted-printable Can anyone help me understand why this might be happening? The output from dovecot -n is: # 2.0.19: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-26-generic-pae i686 Ubuntu 12.04 LTS auth_debug = yes auth_verbose = yes disable_plaintext_auth = no mail_location = maildir:~/Maildir passdb { driver = pam } protocols = " imap" ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } Thanks!

[Dovecot] Erroneous operation not permitted when deleting mailbox with mdbox
by Nikolai Schupbach 01 Aug '12

01 Aug '12

I'm seeing the following error in our logs when removing mailboxes (we are using mdbox and dovecot 2.1.8): Aug 1 20:03:36 msgsrv dovecot: imap(test(a)test.com): Error: stat(/mailstore/domains/test.com/test/mdbox/mailboxes/Spam) failed: Operation not permitted Aug 1 20:03:36 msgsrv dovecot: imap(test(a)test.com): Mailbox deleted: Spam When I run truss against the process it appears the error relates to attempted unlink of a directory, not a stat of it, as reported by the log. However the mailbox does appear to be deleted fine, so it appears to be an erroneous error.

[Dovecot] BUG: LDAP extension failed to authenticate if 'base' DN configuration is empty ''
by Hendy Irawan 01 Aug '12

01 Aug '12

Dear Dovecot developers, We have several context entries and want to authenticate a user against the whole LDAP server. However when setting "base = " Dovecot LDAP fails with following message: Jul 29 10:50:59 nitik1 dovecot: auth: Error: ldap(hendy(a)staging.member.berbatik.com,127.0.0.1): ldap_search((virtualMail=hendy(a)staging.member.berbatik.com)) failed: Other (e.g., implementation specific) error This limits the search to only one base DN, e.g. base = dc=staging,dc=berbatik,dc=com The ldap client library is able to search entries using an empty base DN, so it should be possible for Dovecot LDAP to do the same. An even more elegant solution will be the ability to specify multiple base DNs, but if Dovecot can search the "root DN" (empty string) it would be great. Thank you.

[Dovecot] mdbox with separate index location results in many emptydirectories
by Jürgen Obermann 31 Jul '12

31 Jul '12

Hallo, I use dovecot 2.1.7 with mdbox format and I specified a separate location for mailbox index files with mail_location = mdbox:/dovecot/storage%h:INDEX=/dovecot/index%h With this setting I get for every mailbox a directory under both filesystems /dovecot/index and /dovecot/storage, e.g. for the inbox it looks like that: # ls -lR /dovecot/index/home/hrz/myuser/mailboxes/INBOX /dovecot/storage/home/hrz/myuser/mailboxes/INBOX /dovecot/index/home/hrz/myuser/mailboxes/INBOX: total 49 -rw------- 1 myuser hrz 20480 Jul 20 11:12 dovecot.index.cache -rw------- 1 myuser hrz 1280 Jul 20 08:00 dovecot.index.log -rw------- 1 myuser hrz 301 Jul 19 16:45 dovecot.index.search -rw------- 1 myuser hrz 20 Jul 19 16:45 dovecot.index.search.uids /dovecot/storage/home/hrz/myuser/mailboxes/INBOX: total 3 drwx------ 2 myuser hrz 2 Jul 19 15:20 dbox-Mails /dovecot/storage/home/hrz/myuser/mailboxes/INBOX/dbox-Mails: total 0 As expected the index files now reside under /dovecot/index%h/mailboxes/, but the path /dovecot/storage%h/mailboxes/ also contains for every user and every mailbox name a directory which in turn contains only an empty subdirectory 'dbox-Mails'. These directories seem to me to sum up to a lot of unneded infrstructure objects. I tried to delete these empty directories, but dovecot did not like that and stopped to work. So somehow they are necessary, in spite of setting a separate index file location. So my question is, could these empty directories be avoided, perhaps in a future version?

[Dovecot] Empty argument in "executable = script ..." service
by Florian Wagner 31 Jul '12

31 Jul '12

Hi, what is the point of adding an empty argument to the command called by the "executable = script ..." setting in a service? I guess that would be the call to array_append_space at line 57 in util/script.c. Background is that I'm trying to run bogofilter through the extprograms Pigeonhole plugin. So I've defined a service entry with a unix_listener and wondered why my test shell script works but bogofilter exits with a cryptic error. Turns out that this empty argument at the end trips up the bogofilter argument parsing code. If I manually call bogofilter with execv and add that empty argument I get the same cryptic error. Regards Florian

[Dovecot] Dovecot Director behaviour when two or more fail
by Dominic Malolepszy 31 Jul '12

31 Jul '12

Hi, On the Dovecot wiki here http://wiki2.dovecot.org/Director it says the following: "The directors are going to connect to each others in a ring. For example if you have servers called A, B and C, director will create connections A->B, B->C and C->A" I am curious what happens in a scenario when two or more directors fail and potentially break a ring in half, do the active directors detect this and reform a new ring?

Entries in /etc/dovecot/users look like this: jax@XXX.com:{plain}password The output from 'doveconf -n' is in the attachment to this mail message. I'm a beginner without experience with either IMAP servers or clients. Can you give me pointers to see what I'm missing that causes the errors logged as above? The user data base looks like this: userdb { args = uid=5000 gid=5000 home=/var/vmail/%d/%n/home mail=maildir:/var/vmail/%d/%n driver = static } Being a beginner, I wonder if is necessary to manually make home directories for each '/var/vmail/%d/%n/home'? I've tried test accounts with and without empty "home" directories at the indicated locations without seeing any difference in the error indications. Is it necessary to manually populate the "home" directories? Besides having no clue about the errors logged, I don't understand what it takes to make quotas work nor do I understand what options are available or advisable. The distribution wiki/QuotaMaildir.txt seems clear that the Maildif+++ backend is indicated but beyond that I remain in the dark. FWIW, I've yet to try a real IMAP client. Thank you for any pointers you can give me.

[Dovecot] Problem with running two dovecot instances on the same server
by Alexandr Sabitov 31 Jul '12

31 Jul '12

Hello All, Have anyone met the problem I am struggling with at the moment ? The problem is when I run two instances of dovecot 2.1.8 which are one for proxy-director and another one is a regular one on the same server then I have big amount of strange entries in the /var/log/mail.err: Jul 26 11:51:20 dovecot-test-1 dovecot: director: Error: Empty server list Jul 26 11:51:20 dovecot-test-1 dovecot: director: Fatal: Invalid value for director_mail_servers setting Jul 26 11:51:20 dovecot-test-1 dovecot: master: Error: service(director): command startup failed, throttling for 60 secs Jul 26 11:52:20 dovecot-test-1 dovecot: director: Error: Empty server list Jul 26 11:52:20 dovecot-test-1 dovecot: director: Fatal: Invalid value for director_mail_servers setting Jul 26 11:52:20 dovecot-test-1 dovecot: master: Error: service(director): command startup failed, throttling for 60 secs That's for sure set->director_mail_servers variable in main_preinit of ./src/director/main.c But after dumping it it turns out that ppid of the process which failed to use main_preinit function is a "regular" dovecot not the proxy one. When main_preinit is used by dovecot-proxy then set->director_mail_servers = ip address of a mail server and it is all good but if main_preinit is used by dovecot then set->director_mail_servers = empty and I get fatal errors in logs. So here is a question: How come that "non-proxy" dovecot requests director_mail_servers variable and writes fatal error in the logs if it doesn't find it ? Thank you very much for any assistance!

[Dovecot] maildir_copy_with_hardlinks on v.2.0.19
by mailing list subscriber 31 Jul '12

31 Jul '12

Hi, I'm trying to get the so-called "single instance store" (I think cyrus has got the name for the first time) with dovecot --version = 2.0.19 binary package installed from ubuntu 12.04 lts official repo. I have checked that "maildir_copy_with_hardlinks" is enabled ("dovecot -a|grep hard" shows "yes") then I have installed and enabled the lmtp component of dovecot. The configuration "dovecot -n" is pasted here: http://paste.lug.ro/131180 Also in the same paste is a strace against dovecot and childrent showing evidence of the MTA delivering a single copy of the message via LMTP with multiple RCPT TO: headers. However when looking in the Maildir, I see the mail break down into three separate files instead of expected hardlinked files ("stat" and "ls" shows one single link count, inodes are different) Given the above data, what (am I | dovecot is) doing wrong? Please cc me if you need additional input when replying as I'm not subscribed to the list (I'll watch the thread online only) Many thanks in advance.

Evolution seems to be in pretty widespread > use. Wondering what others like and use heavily. Hi Chris, I tried Evolution once about 10 years ago, and it was too complex and comprehensive for me to understand. The centerpiece of my emailing activity is a Dovecot IMAP server on my daily driver desktop computer. The way it works is that fetchmail grabs all my email from my various POP accounts, pushes them through procmail, whose filters distribute the emails into the proper Dovecot IMAP directories (and also /dev/null stuff from PITA people). As far as I know, my Dovecot has never malfunctioned. Currently, I access my local IMAP with Claws-Mail. Claws is capable, robust, and does what I need without being an ecological disaster like Kmail or intermittently pig slow like Thunderbird. Claws' configuration is difficult to wrap your head around, and very much in need of better documentation, but so far, thanks to a knowledgeable and helpful user community on the mailing list, I've been able to make almost every config change to speed my interaction with Claws. My one complaint about Claws that can't be cured by documentation is its propensity to do everything with one process and one thread, so while you're sending an email or scanning your IMAP, you cannot look at other emails. I also wanted their powerful search to be able to recurse folders, and when nobody volunteered to do it, I tried to do it myself. Making something recursive sounds like simply a matter of writing a simple loop around the existing functionality, but what I found out is, at least this part of Claws was written in a manner resembling MVC, with process and UI completely commingled. For that reason I was unable to make it recursive. I have Claws on my daily driver and all my laptops. Thanks to Kevin Korb's instructions, on the laptops I was able to tell Claws its IMAP server was at 127.0.0.1. I pinholed my OpenBSD/pf firewall appliance to port forward incoming ssh to my daily driver. Then, on my laptop, if I'm at home and on the LAN, I run the following inhouse.sh sudo ssh -NTL 993:127.0.0.1:993 slitt(a)192.168.1.88 While on the road I run this travelling.sh: sudo ssh -NTL 993:127.0.0.1:993 slitt(a)99.99.99.99 In the preceding, 99.99.99.99 is the IP address my ISP gave me, while 192.168.1.88 is the LAN IP address of my daily driver. This makes 127.0.0.1:993 get pushed through ssh to the ISP supplied internet address or the LAN address. So I can use Claws to interact with my daily driver desktop anywhere I go. I'm extremely pleased with this setup. My IMAP tree is trivial to back up, and gives me the assurance that if Claws-Mail ever commits suicide the way Kmail did when they went to Kmail2, I can simply plug in a different IMAP enabled email client. Meanwhile, Claws gives me an extremely productive and easy to use user interface. With my client/server setup, I no longer need to copy all my email too and from the laptop when travelling. I'm going to present on my remote use of my daily driver desktop Dovecot, using Claws and ssh, at tomorrow night's GoLUG meeting.

Hi guys, I'm trying to set up in-mailbox routing for messages using the + delimiter. The server runs postfix and dovecot 1.2.15. I have re-defined the delivery service in master.cf as "-f ${sender} -d ${user}@${nexthop} -n -m INBOX.${extension}" (server was formerly courier) but the routing only works when the destination folder has no uppercase characters. "Folder1" doesn't deliver correctly while "folder2" does. What am I doing wrong? Kurt

[Dovecot] SSL Warnings in Debug Logs

[Dovecot] mysql auth failover failing
by Paul B. Henson 29 Jul '12

29 Jul '12

We are running dovecot to provide authentication for postfix, using two mysql servers in a multi-master replication set as the password source: ---------------------------------------- # 2.0.13: /etc/dovecot/dovecot.conf # OS: Linux 2.6.37-gentoo-r4 x86_64 Gentoo Base System release 2.0.2 auth_mechanisms = plain login digest-md5 cram-md5 auth_verbose = yes passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } protocols = none service auth-worker { unix_listener auth-worker { user = postfix } user = $default_internal_user } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } user = postfix } ssl = no userdb { driver = passwd } --------------------------------------- With an sql config of: ------------------------- driver = mysql connect = host=mysql-1.unx.csupomona.edu host=mysql-2.unx.csupomona.edu dbname=idmgmt user=postfix password=XXXXXXX default_pass_scheme = PLAIN password_query = XXXXXXXXX ------------------------- According to the sample SQL configuration file "HA / round-robin load-balancing is supported by giving multiple host settings, like: host=sql1.host.org host=sql2.host.org". However, as far as I can tell dovecot only connects to the first listed host, and processes all queries through it, there does not appear to be any load-balancing going on. That's not necessarily a dealbreaker; however, high-availability does not appear to be working either. If I shutdown the first mysql server, dovecot starts to log connection failures: Sep 9 15:47:34 tweak dovecot: auth: Error: mysql(mysql-1.unx.csupomona.edu): Connect failed to database (idmgmt): Can't connect to MySQL server on 'mysql-1.unx.csupomona.edu' (111) - waiting for 1 seconds before retry Sep 9 15:47:39 tweak dovecot: auth: Error: mysql(mysql-1.unx.csupomona.edu): Connect failed to database (idmgmt): Can't connect to MySQL server on 'mysql-1.unx.csupomona.edu' (111) - waiting for 25 seconds before retry And postfix starts to fail authentications: Sep 9 15:47:35 tweak postfix/smtpd[5119]: warning: bender.iitsys.csupomona.edu[134.71.250.134]: SASL DIGEST-MD5 authentication failed: Connection lost to authentication server Now and again the authentication process dies: Sep 9 15:47:39 tweak dovecot: auth: Panic: file auth-request-handler.c: line 697 (auth_request_handler_flush_failures): assertion failed: (auth_request->state == AUTH_REQUEST_STATE_FINISHED) Sep 9 15:47:39 tweak dovecot: auth: Error: Raw backtrace: /usr/lib64/dovecot/libdovecot.so.0(+0x3f71a) [0x7f25822ca71a] -> /usr/lib64/dovecot/libdovecot.so.0(+0x3f766) [0x7f25822ca766] -> /usr/lib64/dovecot/libdovecot.so.0(+0x198ca) [0x7f25822a48ca] -> dovecot/auth() [0x4137f4] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handle_timeouts+0xd4) [0x7f25822d5fe4] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handler_run+0x5b) [0x7f25822d6bcb] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_run+0x28) [0x7f25822d5c48] -> /usr/lib64/dovecot/libdovecot.so.0(master_service_run+0x13) [0x7f25822c3de3] -> dovecot/auth(main+0x2be) [0x4179de] -> /lib64/libc.so.6(__libc_start_main+0xfd) [0x7f2581898bbd] -> dovecot/auth() [0x40bdc9] Sep 9 15:47:39 tweak dovecot: master: Error: service(auth): child 4154 killed with signal 6 (core dumps disabled) Requests start to pile up: Sep 9 15:51:46 tweak dovecot: auth: Warning: auth workers: Auth request was queued for 25 seconds, 45 left in queue Lookups time out: Sep 9 15:57:22 tweak dovecot: auth: Error: auth worker: Aborted request: Lookup timed out This occasionally pops up: Sep 9 15:58:38 tweak dovecot: auth: Fatal: net_connect_unix(auth-worker) failed: Resource temporarily unavailable And sometimes the auth process gets temporarily disabled: Sep 9 15:58:57 tweak dovecot: master: Error: service(auth): command startup failed, throttling Resulting in more postfix authentication failures: Sep 9 15:58:57 tweak postfix/smtpd[6531]: warning: bender.iitsys.csupomona.edu[134.71.250.134]: SASL DIGEST-MD5 authentication failed: Sep 9 15:59:08 tweak postfix/smtpd[6551]: fatal: no SASL authentication mechanisms To the point where postfix also temporarily throttles smtpd: Sep 9 15:59:21 tweak postfix/master[6526]: warning: /usr/lib64/postfix/smtpd: bad command startup -- throttling Resulting in a complete unavailability of smtp service, not just unavailability of authenticated services. I don't think all authentications fail during the scenario, but I think the majority do. Based on the network traffic, dovecot is almost continuously trying to connect to the first listed server. It sometimes connects to the second listed server, but when it does, the connection does not persist, it goes away almost immediately. Ideally, I would like no authentications to fail if one of the MySQL servers is unavailable. If a few fail just when the server dies, that would be undesirable but acceptable as long as they do not continuously fail while the server is down. Am I doing something wrong? Does the example sql config have incorrect information? We were previously running dovecot 1.2.11, we just recently upgraded to 2. In the previous version, we actually had two different passdb's configured, each one listing only one of the mysql servers. I seem to recall that was the recommendation at the time for high-availability. When that configuration did not seem to work under version 2, I found an updated recommendation to list both servers in the same passdb, which also does not appear to work correctly. I actually went back and tested the older version, and determined it seemed to work okay in the case where the server was up but the service was down, and connections were refused, but also failed a large number of authentication attempts when the server was completely down and connections were timing out.

[Dovecot] Enable ACL for master user

Hi Team, I have dovecot setup and I have enabled master User login in dovecot.conf file as below :- auth_master_user_separator = * passdb { driver = passwd-file args = /etc/dovecot/passwd.masterusers master = yes pass = yes } passdb { driver = shadow } userdb { driver = passwd } and craeted file. I can login to the user but what I see after login is : - Trying 0.0.0.0... Connected to 0. Escape character is '^]'. * OK [CAPABILITY IMAP4rev1 SASL-IR SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN NAMESPACE LOGIN-REFERRALS UIDPLUS LIST-EXTENDED I18NLEVEL=1 STARTTLS AUTH=PLAIN] Dovecot ready. a login user*masteruser password a OK Logged in. a list "" * * LIST (\HasNoChildren) "." "Trash" * LIST (\Unmarked) "." "INBOX" a OK List completed. However when I login as a normal user I see this : - Connected to 0. Escape character is '^]'. * OK [CAPABILITY IMAP4rev1 SASL-IR SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN NAMESPACE LOGIN-REFERRALS UIDPLUS LIST-EXTENDED I18NLEVEL=1 STARTTLS AUTH=PLAIN] Dovecot ready. a login user userpassword a OK Logged in. a list "" * * LIST (\HasNoChildren) "." "Drafts" * LIST (\HasNoChildren) "." "Trash" * LIST (\HasNoChildren) "." "Sent items" * LIST (\HasNoChildren) "." "INBOX" a OK List completed. I think its because of ACL for user and it is using masterusers ACL. I looked at http://wiki2.dovecot.org/PostLoginScripting, however do we have sample login script so that I can use that script with modifications. Sorry I am new to dovecot. Thanks and Regards.

[Dovecot] Problem with preserving MIME format with Dovecot IMAP and Outlook
by Peter Grimmond 29 Jul '12

29 Jul '12

Hello, I have installed Dovecot 2.0.19 on Ubuntu 12.04 LTS. I have set up a very basic IMAP configuration. I have two different laptops running Outlook (one MacOS, one Windows 7) and I have configured both to connect to the Dovecot service. My problem is, emails in MIME format that I synchronise from one Outlook client are not being correctly decoded as MIME messages on the other client. Instead, the message is rendered in plaintext, starting with the lines: This message is in MIME format. Since your mail reader does not understandthis format, some or all of this message may not be legible. --B_3426360453_22814Content-type: multipart/alternative; boundary="B_3426360453_4099" --B_3426360453_4099Content-type: text/plain; charset="ISO-8859-1"Content-transfer-encoding: quoted-printable Can anyone help me understand why this might be happening? The output from dovecot -n is: # 2.0.19: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-26-generic-pae i686 Ubuntu 12.04 LTS auth_debug = yes auth_verbose = yes disable_plaintext_auth = no mail_location = maildir:~/Maildir passdb { driver = pam } protocols = " imap" ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } Thanks!

Dumping out this field using doveadm -ftab fetch -A \ "mailbox date.saved" \ $ mailbox Trash OR mailbox Junk OR mailbox "Deleted Items" $ it seems the timestamps do not actually correspond to when the client moves messages to their trash folder, but rather, to the time I query for it i.e. a query instantiates this value. This timestamp is then retained. In practice, if this query is done on a periodic interval (e.g. daily), the date.saved will be roughly correct, and is usable as an age test for expungement. Is there a way to force this value to be cached when the client actually saves or moves a message? Joseph Tam <jtam.home(a)gmail.com>

28 Jul '12

Hi, current version of courier migration script courier-dovecot-migrate.pl preserve order of POP3 UIDLs, but it keep IMAP UIDs not in order which cause problems with clients using IMAP along with POP3 in some cases. Attached patch use MAIL_FETCH_POP3_ORDER feature added in version 2.0.13 to keep POP3 and IMAP UID[L]s in order. -- [ Ohodnotte kvalitu mailu: http://nicereply.com/websupport/4afafd34/ ] Pavel Stano | admin team http://WebSupport.sk *** TAKE AND ENJOY ***

[Dovecot] Dsync replication
by list＠airstreamcomm.net 28 Jul '12

28 Jul '12

I have been loosely following discussions dsync replication, but I am wondering if this tool still in a testing phase or has it been committed as a production part of Dovecot? I would like to do some testing with the protocol to see if it's capable of handling the change rate our mail service generates, which has about 23,000 active users. We are trying to find solutions for a two site setup where mail processing is either being done at the primary data center A and fails over to a hot standby cluster at the secondary data center B, or where both data centers are doing active processing. I have been unable to find documentation on dsync replication on the wiki, so if there is any documentation available on how to setup dsync replication I would appreciate a nudge in the right direction.

[Dovecot] fts-lucene vs SEARCH HEADER
by Matthew Powell 28 Jul '12

28 Jul '12

Hello. This is in Dovecot 2.1.7 on Linux x86, but it looks as though 2.1.8 has the same issue. I'm using fts-lucene. SEARCH HEADER TO returns no results, but SEARCH TO works: B SEARCH TO TEST * SEARCH 1 2 3 4 5 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 24 26 27 28 29 31 B OK Search completed (0.000 secs). C SEARCH HEADER TO TEST * SEARCH C OK Search completed (0.000 secs). Without FTS enabled, both forms of the query work. It looks as though the header names are indexed in lower case. But Dovecot is passing the header name to the backend in upper case when SEARCH HEADER is used. I'm not sure whether this is the *right* fix, but lower-casing the header name in lucene-wrapper.cc seems to fix the problem: --- dovecot-2.1.7-clean/src/plugins/fts-lucene/lucene-wrapper.cc 2011-12-13 06:35:29.000000000 -0500 +++ dovecot-2.1.7/src/plugins/fts-lucene/lucene-wrapper.cc 2012-07-24 14:03:14.000000000 -0400 @@ -1094,7 +1094,7 @@ return false; q = lucene_get_query(index, - t_lucene_utf8_to_tchar(index, arg->hdr_field_name, FALSE), + t_lucene_utf8_to_tchar(index, t_str_lcase(arg->hdr_field_name), FALSE), arg); break; default: Now: B SEARCH TO TEST * SEARCH 1 2 3 4 5 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 24 26 27 28 29 31 B OK Search completed (0.000 secs).
