[Dovecot] Just trying to make dovecot work.

Hi, I have to say that Dovecot is certainly the most challenging piece of software I've ever had the pleasure of setting up (due mainly to the reams of largely unhelpful documentation). After 36 almost non-stop hours reading and trying, I finally end up here. :-) I really would appreciate your help - and many thanks in advance! *************************************************************** /var/log/dovecot.info.log (showing unsuccessful login) *************************************************************** Aug 04 21:32:36 auth: Debug: Loading modules from directory: /usr/lib64/dovecot/auth Aug 04 21:32:36 auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libauthdb_ldap.so Aug 04 21:32:36 auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_sqlite.so Aug 04 21:32:36 auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libmech_gssapi.so Aug 04 21:32:36 auth: Debug: passwd-file /usr/local/etc/dovecot.passdb: Read 1 users Aug 04 21:32:36 auth: Debug: auth client connected (pid=24769) Aug 04 21:32:41 auth: Debug: client in: AUTH 1 PLAIN service=imap securedlip=::1 rip=::1 lport=143 rport=52551 resp=AHBldGVyAGZ1YXNpbjU0MTRz Aug 04 21:32:41 auth: Debug: passwd-file(peter,::1): lookup: user=peter file=/usr/local/etc/dovecot.passdb Aug 04 21:32:41 auth: Debug: client out: OK 1 user=peter Aug 04 21:32:41 auth: Debug: master in: REQUEST 1417805825 24769 1 44a3aec60ec6eaec6eff0efb99971eee Aug 04 21:32:41 auth: Debug: master out: USER 1417805825 peter Aug 04 21:32:41 imap-login: Info: Login: user=<peter>, method=PLAIN, rip=::1, lip=::1, mpid=24772, secured *************************************************************** END *************************************************************** *************************************************************** /var/log/dovecot.log (showing unsuccessful login) *************************************************************** Aug 04 21:32:41 IMAP(peter): Error: user peter: Couldn't drop privileges: User is missing UID (see mail_uid setting) Aug 04 21:32:41 IMAP(peter): Error: Internal error occurred.

[Dovecot] getting rid of old spam from +spam Maildir ?
by Voytek Eymont 06 Aug '12

06 Aug '12

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

[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. Here is the truss output from the "3 DELETE INBOX.Spam" IMAP command: gettimeofday({1343808204.962165 },0x0) = 0 (0x0) gettimeofday({1343808204.962351 },0x0) = 0 (0x0)

[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?

[Dovecot] Help needed with configuration giving dict error No such file
by Ajax 31 Jul '12

31 Jul '12

Each time a mail message is delivered to a mailbox records like the following appear in /var/log/dovecot.warn: Jul 29 10:02:05 iris dovecot: lmtp(29320, jax(a)XXX.com) Error: file dict commit: file_dotlock_open(/var/vmail/XXX.com/jax/home/maildir/dovecot-quota) failed: No such file or directory Jul 29 10:02:05 iris dovecot: lmtp(29320, jax(a)XXX.com) Error: file dict commit: file_dotlock_open(/var/vmail/XXX.com/jax/home/maildir/dovecot-quota) failed: No such file or directory Jul 29 10:02:05 iris dovecot: lmtp(29320, jax(a)XXX.com) Error: dict quota: Quota update failed, it's now desynced This is with Dovecot 2.1.7 installed by Debian Squeeze binary packages, dovecot-core v 1:2.1.7-2~bpo60+1, and friends. The host is running GNU/Linux 3.2.0-0.bpo.2-amd64 and on a xfs filesystem. 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.

[Dovecot] Address extensions

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] mysql auth failover failing

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".

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) "."

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>

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.

[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).

[Dovecot] Auto logging-out client
by Nicolás 28 Jul '12

28 Jul '12

Hi list! I'm writing because of an issue I'm having with my Postfix-Dovecot installation. Everything's working fine but when an IMAP client is idle for some time, Dovecot automatically logs it out. Jul 26 14:01:16 mail dovecot: imap(nicolas(a)devels.es): Disconnected: Logged out bytes=1271/7439 This entails errors when trying to send e-mails after this auto logout, such as: host devels.es[91.215.158.237] said: 550-Please turn on SMTP Authentication in your mail client, or login to the 550-IMAP/POP3 server before sending your message. Which result in a very annoying and continuous proccess of restarting my mail client. Is there a way to avoid this auto-logout, or at least configure the time after I want idle clients to auto-logout? Thank you very much! Nicolás

[Dovecot] Slightly OT - Winbind and remote authentication.
by Simon Brereton 28 Jul '12

28 Jul '12

Hi I was doing some research on setting up a samba server for my internal network (as an alternative to NAS). The setup looks easy enough, but then I got to thinking - I already have an internet host with an mysql DB that has usernames and passwords and it would be simpler all round to reuse that as the authentication server. That server is also running Dovecot, so I thought it might be simpler still to set up samba to authenticate using IMAP (the mysql server is not accessible on port 3306 anyway). A quick google resulted in a suggestion from Robert (who by now must be on every single list I'm on or rather vice-versa) about using winbind. I went off to the link he posted - http://wiki.dovecot.org/Authentication/Mechanisms/Winbind?highlight=%28winb… and the problem is that seems to indicate bind and dovecot are on the same server. So, this not being the samba list notwithstanding, is it possible to use a remote dovecot host as an authentication back-end on a local samba installation? Cheers Simon

[Dovecot] Problem overriding default quota limit
by RAUL JAREÑO MORAGO 28 Jul '12

28 Jul '12

Hi, We get user's quota limit from LDAP. It works fine when user has quota attribute in LDAP (this is when it's different from default quota). But when user doesn't have quota limit attribute Dovecot doesn't take default value defined in quota plugin and assign unlimit quota to user.

[Dovecot] emails are being marked as read auto-magically
by Joe Beaubien 28 Jul '12

28 Jul '12

Hi, I'm having a weird issue with dovecot 2.1.7 (using the latest thunderbird client). Something, I have emails that mark themselves as read on their own. No one touches them, and they get marked as read. I try to re-mark them as unread, but a few seconds later, they get marked as read again. The same problem happens in reverse (emails marks as unread become read). Has anyone ever experienced anything similar? I cannot see any warnings or errors in the dovecot logs, so I'm not sure if the problem is with thunderbird or with dovecot. However, I have never had this issue before switching from dovecot 1.0.X to dovecot 2.1.X. Unfortunately, we updated the thunderbird versions around the same time, so I feel like a dog chasing my tail on this issue. Any help would be appreciated. Regards, -Joe

I just tried configuring the submission port on postfix but the problem persists even sending by port 587. About what Harald said, I guess I initially missed the point of the problem, it was just my conclusion because that error happens always after the logout message appears, and SMTP authentication is set on my client, so I deduced the problem had something to do with the logout thing. The curious thing is it just happens with SMTP, not with POP3/IMAP protocols. Thanks again! Nicolás

[Dovecot] Sieve & Adding headers.
by Steven Haigh 26 Jul '12

26 Jul '12

Hi all, I've just migrated my mail system from procmail to managesieve/sieve and I'm having trouble trying to duplicate a could of rules I used to use in my procmail config. One particular rule would be this: :0 Wfh * ^Sender: owner-scientific-linux-devel(a)LISTSERV.FNAL.GOV | (sed -e '/^Subject:/ s/\[SCIENTIFIC-LINUX-DEVEL\] *//g'| sed ':a;N;$!ba;s/Precedence: list/Precedence: list\nList-Post: <mailto:scientific-linux-devel@fnal.gov>/g') :0 A .Mail\ Lists.SL-Devel/ This in effect adds the header "List-Post: <mailto:scientific-linux-devel@fnal.gov>" after "Precedence: list". This allows me to use the Reply To List functionality in Thunderbird. Another rule is: :0 Wfh * ^X-BeenThere: users(a)lists.repoforge.org | sed -e '/^Subject:/ s/\[users\] *//g' :0 A .Mail\ Lists.RPMForge/ This removes the [users] tag from the subject of each message to the RPMForge / RepoForge mailing lists. Is there a way to do this with sieve? Nothing I have seen seems to do this - however I'm only a beginner in this area. Please CC myself as well as the list. I'm not currently subscribed. -- Steven Haigh Email: netwiz(a)crc.id.au Web: http://www.crc.id.au Phone: (03) 9001 6090 - 0412 935 897 Fax: (03) 8338 0299

Starting on July 24 I started seeing the following type lock files I the /var/mail directory. -rw-rw-rw- 1 agab mail 0 Jul 24 10:08 agabriel.lock.1343138908.28535.hardy.purdue.edu -rw-rw-rw- 1 agab mail 0 Jul 24 10:08 agabriel.lock.1343138907.28535.hardy.purdue.edu -rw-rw-rw- 1 agab mail 0 Jul 24 10:08 agabriel.lock.1343138906.28535.hardy.purdue.edu -rw-rw-rw- 1 agab mail 0 Jul 24 10:08 agabriel.lock.1343138905.28535.hardy.purdue.edu They are being created by only three of our users. What is common with the three users is that they are using alpine mail client. Again these just started on July 24. We have over 300 user and a lot of them use alpine but only three users seem to generate these lock files. Can some one tell me what and why these are being created and why they are not getting destroyed? Thanks Robert _____________________________________________________________________ Robert P.

[Dovecot] deleted-to-trash plugin problems
by Steve Platt 24 Jul '12

24 Jul '12

We have a user who wants to use Outlook with our Dovecot IMAP server but doesn't like the way Outlook handles deletion with IMAP. Ironically she would like Outlook to move the message to her Trash folder, just like Outlook does with "local" folders, I guess. So I enabled the "deleted-to-trash" plugin (v0.3) on our Dovecot 1.2.17 server (built for SPARC, solaris 10, btw). The problem is that it doesn't seem to work; the message doesn't even appear to get marked for delete. The imap log says: "opening Trash succeeded" and then nothing else! I have found that there is a copy of the message in .Trash/tmp/ suggesting that the plugin may be bailing out part way through. Has anyone any idea what's wrong please? I'll attach the output of dovecot -n ... Thanks, Steve

Morten Stevens <mstevens(a)imt-systems.com> writes: > So it is now RFC compliant. Anyway I think delaying mail traffic is not > a good solution. Well, OK, if you not keen on greylisting, you can try greet pausing, which introduces a shorter delay. It tests a bot's patience by inserting a pre-HELO pause. RFC allows 5 minutes before timeout. This is last week's stat for one of my mail server and the count of early-talker or early-disconnecter, almost all of which are bots. A greet pause of over 20s dumps a lot of bots. Expect to whitelist the odd server here and there because they've tuned their servers to some aggressively small RFC non-compliant timeouts.

That's another problem with the poor IT guy trying to assemble bricks from different vendors: when he finally is heard, the answer is "uhm, the feature you requested fail beyond the scope of my brick. I'm sorry, I can't do that", even when there is a proposed patch available! If you read carefully all my referenced links you'll find one that is listing other imap servers that support it.

Unfortunately that feature only addresses PROVISIONING of data, which is quite unuseful since cyrus mail admins do this with the auto-* uoa.gr patches (that's another pain that devs refused to include for a long time) - What it lacks is the ability to handle CHANGE (change of default script, or alter existing user scripts).

[Dovecot] Couple of questions about the logs
by Steve Campbell 23 Jul '12

23 Jul '12

The log entries for imap disconnection shows a "bytes = x/y" format where the x equals bytes sent from client and y equals bytes received from client. Can someone explain that a little better to me, please? In an imap account, does this "y" represent the size of the header information being returned to the client or the amount of data of the email mailbox? Also, is there a way to tell if an email has been deleted (or marked for deletion) when using an imap client? Here's the situation: I've got a user who uses imap when using his phone and webmail. When in the office, he uses a pop3 client on his desktop. He indicates he's missing some emails from the weekend when first turning on his desktop. I know of no way to discover if he's deleted and then purged email from his mailbox using imap clients. I've checked the logs and he does not access his mailbox simultaneously from any of the 3 clients. I can find 31 emails he received since his last pop login on Friday until his first pop login on Monday. The pop login indicates he received only 27 emails during the pop retrieval. I'm a little lost here. Any help would be appreciated in interpreting the logs or suggesting how this might have happened. thanks steve campbell

[Dovecot] Performance based choices
by Hans J. Albertsson 22 Jul '12

22 Jul '12

I've stopped trying to find a HowTo that suits me right away, and instead I am happily trudging thru the Dovecot wiki, article by article. I have right up front thought of one question, a general one, and some detailed versions of that same question: Generally, is there much general performance and reliability background data available for making the basic choices? Say: 1st. delivery: maildrop or LDA or LMTP? I tend to think LMTP should be the ideal choice for me, from what I've gleaned so far. Above all it means that there's only one conceptual thing that needs to know, and postfix and other stuff can safely let dovecot deal with accessing and finding mailboxes. And it won't start and stop thousands of processes. 2nd. mailbox format: Maildir and mbox are the older forms. Are there any advantages to using dovecot's dbox instead? mdbox strikes me as having the potential for being a fast and reliable format. Is that an accurate impression? And, is mdbox mature enough for me to forget maildir and mbox? 3rd. I'm aiming for a poor man's High Availability system: I'm using zfs, and I'm hoping to place all config data for dovecot and postfix and everything else in one zfs file system, and all the user owned data (what should normally go in a home directory) in another (or two or three other) zfs file systems. Then I'm planning to copy over all data at regular intervals, to a second, normally passive, mail server. If the main server breaks, we'll manually (or using scripts and autodetection) fail over to the passive one, making it active, and turning power off to the failed guy using IPMI. The data transfer is to be zfs send/zfs recv over a separate highly redundant network connection. Is this a reasonable idea, or is there some advantage to letting dsync do some of the copying??? Or is there some totally different alternative? iscsi? 4th. With about a thousand users/accounts: does MySQL pay off? Or is LDAP the way to go? Or will a dovecot-specific passwd-file do the job well enough? Those are the three I'm used to since before. I'd like to stay with the flat file, but not the system password file: we're not going to let users in except into dovecot.

[Dovecot] Corrupted dbox file - purging found mismatched offsets

Hi, we are running a cluster using mdbox on NFS with director+mailbox on each node. After running our daily doveadm purge loop over all users, we got dbox corruption... doveadm user "*" |\ while read username do doveadm -c /etc/dovecot-director/dovecot-director.conf -D purge -u "$username" done For one user (which deleted a lot of messages from his mailboxes today), we got the following error in the dovecot.log: Jul 22 20:10:36 10.129.3.213 dovecot: doveadm(user(a)example.org): Error: Corrupted dbox file /mail/dovecot/example.org/user/mail/storage/m.24 (around offset=1380859): purging found mismatched offsets (1380829 vs 920527, 3/61) Jul 22 20:10:36 10.129.3.213 dovecot: doveadm(user(a)example.org): Warning: mdbox /mail/dovecot/example.org/user/mail/storage: rebuilding indexes What does this message exactly tell me and how to prevent this in the future?

[Dovecot] Confusion when trying to set up a first postfix+dovecot mailserver
by Hans J. Albertsson 22 Jul '12

22 Jul '12

I'm trying to set up a first test for a dovecot + postfix (+ many other things) mail server for about 1000 accounts, and I keep stumbling on confusing inconsistencies in the HowTo documents I'm trying to follow. I tried to do a simple setup with virtual users using a howto saying it was for just that and that it's for Dovecot 2.x, and it shows a few text chunks to put in files, and then says it's better to do the changes in the example-config conf file.... And then the whole structure of config files and dirs is totally different from what is implied in the howto. And of course it won't run. Probably because of the structure of a conf.d dir is multiple files, and the instructions are explicitly written for the case of having a single conf file. Can anyone suggest an order in which to read docs that will take me thru w/o being totally confusing? I would very much like to be able to enable bit by bit, rather than have to understand all of dovecot before I can even begin to test it. P.S: I want to setup a server using postfix+dovecot+tls+virtualusers+maildir+dspam+mailman, at least that's the target I'm aiming for. Please suggest a good HowTo for this setup that will not be too confusing. Also, Sorry if I sound like a whining kid: I am new to dovecot and postfix, but I was a software support engineer for Sun for ages, and I should really be able to manage this if I just had some consistent and non-confusing HowTo or Tutorial to follow as a first try.

[Dovecot] Director for smtp-auth

Hi all, isn't it possible to use the director functionality for smtp-auth too? I have a frontend system for imap and outgoing mails using sasl and I recognized that all sasl username/password combinations are accepted as these credentials aren't checked by the backend servers. Regards Patrick

[Dovecot] postfix/sendmail configuration
by Gary Partis 20 Jul '12

20 Jul '12

Hi all I have searched the net and cant find anything relating to this. In 15-lda.conf, the default sendmail is used to send messges from Dovecot, such as "out of hours" and "redirected" emails controlled by sieves. However, postfix/sendmail is looking in /etc/postfix/main.cf for the configuration file (as logged in /var/log/maillog), but I have the config file elsewhere, and I even have MAIL_CONFIG setup to point to the true config directory. Is there a method of setting 15-lda.conf sendmail config to ensure it uese the correct postfix config file? Thanks in advance Gary

[Dovecot] Append with literal+ and mailbox over quota
by Ewald Dieterich 19 Jul '12

19 Jul '12

I'm appending a mail with literal+ to a mailbox that is over quota: 1 APPEND INBOX {127+} From: <ewald.dieterich(a)fun.de> To: <ewald.dieterich(a)fun.de> Subject: Quota-Test Message-ID: <abcdefg(a)fun.de> Quota-Test 1 NO [OVERQUOTA] Quota exceeded (mailbox for user is full) 2 NOOP 1 BAD Error in IMAP command APPEND: Invalid arguments. 3 NOOP 3 OK NOOP completed. Somehow the first NOOP is considered to be part of the already failed APPEND. I have to add an empty line after to NO response for the NOOP to work: 1 APPEND INBOX {127+} From: <ewald.dieterich(a)fun.de> To: <ewald.dieterich(a)fun.de> Subject: Quota-Test Message-ID: <abcdefg(a)fun.de> Quota-Test 1 NO [OVERQUOTA] Quota exceeded (mailbox for user is full) 2 NOOP 2 OK NOOP completed.

[Dovecot] Converting from Maildir format ?
by Nick＠5sg.eu 19 Jul '12

19 Jul '12

Hi again, I'm still trying to find out if anyone knows the correct way to either switch the existing Maildir multiple file format to the single file format I believe known as MBox. Failing that, though it'll mean a LOT of work for me to manually convert all of the existing Maildirs, how do I get dovecot to work in future in MBox single file format. I tried entering 'mail_location = mbox:~/mail:INBOX=/%h/%u' in the 'dovecot.conf', but it still saves each message in a file of its own in the /new /cur /tmp directories ??

Whilst I would normally agree, at the same time I've had a fair amount of experience with dovecot and sendmail (been running them for over 10 years). Pigeonhole is new to me, however. . . > One thing I did notice is that you are sending this mail from an internal IP... since most people use very different checks for such mail (bypassing many/most checks), maybe you should be testing from an external address (one that comes in from outside your network)? So I have a DMZ that houses the mail server for my domain, which is where the private addresses are. Connections are passed through the OpenBSD router to the mail server. So testing from an external address would be essentially the same (since the connection to the SMTP server talks to the sendmail process as the /usr/lib/sendmail process). Regardless, my original tests were sending mail from the Mac off-network. > Also, it is always recommended when setting up a new server to start with the latest version... for 2.0.x that would be 2.0.19, but the latest is 2.1.8... When I set it up, 2.0.13 _was_ the latest. :-) I was hoping to avoid the pain of recompiling dovecot and pigeonhole. Not that big a deal, I guess. . . >> lda_original_recipient_header = X-Original-To >> lmtp_save_to_detail_mailbox = yes > > Ok, I think this is the problem... > > Dovecot's LMTP currently does NOT preserve the x-original-to header... in fact, brought this up recently (I was one of the ones interested in Timo adding support for it) on this (and the postfix, which is what I use) on this very list: > > http://www.dovecot.org/list/dovecot/2012-April/065075.html > > Apparently, after Timo discussed this on the postfix list, he determined that it would not be a very significant change for him to make to add support for this header in LMTP and that he would get to it sooner than later, but as of now, it has not been added. Actually, I'm not using lmtp. I whacked the lmtp_save_to_detail_mailbox in an effort to see if that was the issue before I realized I don't have it turned on. dovecot.conf has: protocols = imap though in 20-managesieve.conf I have: protocols = $protocols sieve I just turned it off and restarted dovecot (though lmtp was not running) and re-ran the test with the same result. So, I think what's going on is pretty straightforward. The local mailer definition in the sendmail.cf file is: Mlocal, P=/usr/local/libexec/dovecot/dovecot-lda, F=lsDFMAw5:/|@qSPhn9, S=EnvFromL/HdrFromL, R=EnvToL/HdrToL, T=DNS/RFC822/X-Unix, A=/usr/local/libexec/dovecot/dovecot-lda -d $u This is more or less right out of the wiki. Since dovecot-lda is passed the -d option, it's using that (and only that) for delivery. Since there's no X-Original-To: header, it doesn't really have any option (since the non-envelope-to address might not exist, or point to something other than the end user's mailbox, etc). It would appear that I have two options: 1) Figure out what macro(s) is(are) valid to pass to dovecot-lda with the -a option in the sendmail config file (sendmail.cf). 2) Get sendmail to put "X-Original-To: <address>" in the header. Both would appear to be a sendmail issue, not a dovecot/pigeonhole issue. Everything I find on the web seems to center around how to use plus addressing to accept mail from multiple email address and filter it into a single address for delivery, only to have the local delivery agent break it back out again. That's not my issue. :-( Sean Sean

[Dovecot] doesn't work at all

Hi, I can't seem to get dovecot to work. When I connect with thunderbird, tbird complains that it can't find the settings for my email.

[Dovecot] SQLite dovecot query caching
by Dominic Malolepszy 19 Jul '12

Hi, I am wondering if Dovecot caches SQLite queries, and how well it works in high performance setups. I am particularly interested because in the below thread SQLite has been suggested as a means of Dovecot proxying connections to different ports. http://old.nabble.com/director%3A-non-standart-ports-at-backends-td33991991… Cheers, Dominic.

[Dovecot] MySQL dict issues
by list＠airstreamcomm.net 18 Jul '12

18 Jul '12

Testing using the mysql dict for quota storage (dovecot-2.0.12-2_127.el5), and ran into a couple issues. First is a permissions issue: dovecot: lmtp(26786, dude(a)test.tld) Error: net_connect_unix(/var/run/dovecot/dict) failed: Permission denied (euid=5000(<unknown>) egid=5000(<unknown>) missing +r perm: /var/run/dovecot/dict, euid is not dir owner) The file /var/run/dovecot/dict is listed with srw------- perms. I changes the perms to srw----rwx and it works, but I would like to figure out how to configure properly to run with the uid and gid 5000 as this is the user for virtual mail. The second issue is that two identical rows are created in the mysql database for each user quota. The next message delivered updates both rows. Here is my quota config: 90-quota.conf: plugin { quota_rule = *:storage=10G quota_rule2 = Trash:storage=+10% } plugin { quota = dict:user::proxy::userquota } dict { userquota = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } dovecot-dict-sql.conf.ext: connect = host=a.b.c.d dbname=mail user=user password=derp map { pattern = priv/quota/storage table = domain_user_quotas username_field = username value_field = bytes } map { pattern = priv/quota/messages table = domain_user_quotas username_field = username value_field = message_count } The last issue might be a documentation omission. Dovecot warned me that the mysql user did not have DELETE privileges on the quota table: dovecot: dict: Error: sql dict: commit failed: DELETE command denied to user 'user'@'a.b.c.d' for table 'domain_user_quotas' The quota dict documentation (at http://wiki2.dovecot.org/Quota/Dict) does not mention DELETE being needed: MySQL uses the following queries to update the quota. You need suitable privileges. INSERT INTO table (bytes,username) VALUES ('112497180','foo(a)spam.dom') ON DUPLICATE KEY UPDATE bytes='112497180'; INSERT INTO table (messages,username) VALUES ('1743','foo(a)spam.dom') ON DUPLICATE KEY UPDATE messages='1743'; UPDATE table SET bytes=bytes-14433,messages=messages-2 WHERE username = 'foo(a)spam.dom';

Hello! I've just upgraded dovecot from 2.0.18 to 2.1.8 and configured impac. I notice dovecot/imap throws segfault from time to time. I'm not sure i know what steps are needed to reproduce problem.

[Dovecot] expire-tool stops on first box with nothing to expire in it
by Michael Wessel 18 Jul '12

18 Jul '12

Hi, I'm running dovecot 1.2.11 on Centos and have the expire plugin enabled. I've had this in place for some time but until now never actually ran the expire-tool. I'm now trying to put this to use. The expire plugin as such is working fine and also the tool is working fine - up to a point. When I run it with --test it goes through a bunch of boxes and lists the messages it would expunge and the new date being logged at the end. As soon as it hits the first box that has nothing in it that's expired however, it stops and goes no further. As an example here are the last two lines of the output when I just ran it: Info: user(a)domain.com/Trash: timestamp 1342320464 (Sat Jul 14 19:47:44 2012) -> 1342937319 (Sat Jul 21 23:08:39 2012) Info: nextuser(a)domain.com/Trash: stop, expire time in future: Sat Jul 14 20:41:49 2012 If I run it again after the indicated expire time it will now also go through the nextuser(a)domain.com but then again stop as soon as it encounters another user with nothing to expire. As far as I can tell the same happens when I actually run the tool. Harder to tell of course as there is no output, but I can tell that not all boxes are expunged as they should be. Any ideas why this would be? Any way to get debug logging on this? Michael

[Dovecot] Compile issue Dovecot 2.1.8, OS X 10.6.x
by Jim 18 Jul '12

18 Jul '12

Hey all. I'm running Mac OS X 10.6.4, and had Dovecot 2.0.7 installed built from source. I'm now wanting to upgrade to Dovecot 2.1.8, but I can't get MAKE to finish without errors: ./configure --with-mysql (snip) Install prefix . : /usr/local File offsets ... : 64bit I/O polling .... : kqueue I/O notifys .... : kqueue SSL ............ : yes (OpenSSL) GSSAPI ......... : no passdbs ........ : static passwd passwd-file pam checkpassword sql : -shadow -bsdauth -sia -ldap -vpopmail userdbs ........ : static prefetch passwd passwd-file checkpassword sql : -ldap -vpopmail -nss SQL drivers .... : mysql : -pgsql -sqlite Full text search : squat : -lucene -solr sudo make (snip) Undefined symbols: "_libiconv_open", referenced from: _charset_to_utf8_begin in libcharset.a(charset-iconv.o) "_libiconv", referenced from: _charset_to_utf8_reset in libcharset.a(charset-iconv.o) _charset_to_utf8 in libcharset.a(charset-iconv.o) "_libiconv_close", referenced from: _charset_to_utf8_end in libcharset.a(charset-iconv.o) ld: symbol(s) not found collect2: ld returned 1 exit status make[3]: *** [libdovecot.la] Error 1 make[2]: *** [all-recursive] Error 1 make[1]: *** [all-recursive] Error 1 make: *** [all] Error 2 The reason for the 'sudo make' was to get around a permissions issue, but I don't think that's related to my issue here. I had build Dovecot 2.0.7 and earlier without issue on this system, but I'm a bit stumped on this particular problem. I also found that the configure parameter --with-sql-drivers no longer seems to work, even though it's still shown in the wiki for 2.x. As far as I can tell, I had used this parameter when compiling 2.0.7.

[Dovecot] Different LDAP filters for different protocols
by James Devine 18 Jul '12

18 Jul '12

Is it possible to query LDAP differently for different protocols? I am using dovecot for both pop3/imap and lmtp deliveries and there are different enable flags in ldap for them. I tried wrapping user_filter inside the protocols in the file dovecot-ldap.conf.ext as shown below but this didn't seem to work. protocol lmtp { user_filter = (&(objectClass=posixAccount)(cn=%u)(active=1)(msmtp=1)) } protocol imap { user_filter = (&(objectClass=posixAccount)(cn=%u)(active=1)(mpop=1)) } protocol pop3 { user_filter = (&(objectClass=posixAccount)(cn=%u)(active=1)(mpop=1)) }

[Dovecot] outlook and redirect sieve
by Lazy 18 Jul '12

18 Jul '12

Hi Aall, we are having issues with outlook clients, running exchange or lotus being unable to parse the email messages redirected by dovecot's sieve 0.3.1, the command is plain redirect "email(a)lotusmail.xxx"; redirects from mta also work correctly exchange was fixed by removing this commit http://hg.rename-it.nl/dovecot-2.1-pigeonhole/raw-diff/082216ad12d6/src/lib… are there any other modifications to the email body or headers that can make those mesages not parsable for outlook ? looking at http://hg.rename-it.nl/dovecot-2.1-pigeonhole/raw-diff/082216ad12d6/src/lib… maybe removing HEADER_FILTER_NO_CR fromi_stream_create_header_filter() will make redirected messages more in tact ? what can I do to make redirect more verbatim ? Thanks in advance for any information. Regards, Michal Grzedzicki

[Dovecot] Selective TLS per local IP
by Robert Blayzor 17 Jul '12

17 Jul '12

We have the requirement to provide SSL on some IP addresses, but not others on our servers. Providing SSL is the easy part and we're able to use multiple SSL certificates now. (thanks Timo!) All is working ok, but we several IP hosts that do not require SSL and do not have valid certificates. While we can limit access via a firewall ACL to TLS connect ports (993/995) we can't do so on port 110/143. The problem is that some clients now are smart enough to look for an offered STARTTLS or STLS, and if it's offered, they try to use it. While not normally a problem if your setup for SSL with valid key/certs, if you have a self signed or no CERT at all, it starts connection warnings and errors on the client side. So is there any way possible to turn off advertising of TLS on port or turn it off/on per IP? Something like: ssl = yes ssl_cert = </etc/ssl/cert/default.pem ssl_key = </etc/ssl/cert/default.pem local 10.1.1.1 { protocol imap { ssl_cert = </etc/ssl/cert/site1.pem ssl_key = </etc/ssl/cert/site1.pem } protocol pop3 { ssl_cert = </etc/ssl/cert/site1.pem ssl_key = </etc/ssl/cert/site1.pem } } local 10.1.1.2 { ssl = no } *or* ssl = no local 10.1.1.1 { ssl = yes protocol imap { ssl_cert = </etc/ssl/cert/site1.pem ssl_key = </etc/ssl/cert/site1.pem } protocol pop3 { ssl_cert = </etc/ssl/cert/site1.pem ssl_key = </etc/ssl/cert/site1.pem } } -- Robert Blayzor INOC, LLC rblayzor(a)inoc.net http://www.inoc.net/~rblayzor/

[Dovecot] [PATCH] Interop problem with Cyrus SASL and GSSAPI
by Ben Morrow 17 Jul '12

17 Jul '12

[I sent this a while ago, but it seems not to have made it to the list. I'm resending it having subscribed first; I apologise if anyone get it twice.] I have been trying to get a Postfix mail server using Dovecot SASL to accept GSSAPI AUTH from another Postfix server using Cyrus SASL, and I believe I have found a couple of bugs in Dovecot's GSSAPI implementation. The first problem is that, because of the way the client invokes libsasl, it sends a GSSAPI request which does not ask for mutual authentication. This means that on the server gss_accept_sec_context returns GSS_S_COMPLETE with a zero-length output token. Dovecot currently sends this to the client as a zero-length continuation response, but this is incorrect according to RFC 4752: what it ought to do instead is proceed straight to the security layer negotiations, and send a gss_wrap packet. The second is that Cyrus sends an empty authz identity; that is, the security layer negotiation packet, when gss_unwrapped, is exactly 4 bytes long. Dovecot objects to this, but in RFC 4422 this is explicitly allowed, and means the authz identity is identical to the authn identity. I believe the attached patches (for the 1.2 and 2.1 branches) fix the problem, though I'm not entirely sure if the difference between the p_strndup in mech_gssapi_unwrap and the t_strndup in get_display_name is important.

[Dovecot] Feature request
by Malloc Kilobyte 17 Jul '12

17 Jul '12

Hi, I am implementig Dovecot as a part of my new e-mail server, which is aimed to be replacement for proprietary software I've been using sofar. Appreciating all Dovecot rich features, I lack just one. And this is the ability to customize the "quota exceeded, message rejected" message. I know I can set it's default content using quota_exceeded_message parameter, but i would also like to have ability to set: - to whom the message is sent. Some mail systems send copy not only to the sender, but also to the recipient. It makes sense in case rejected message has big size. - it's subject - if the rejected message is being attached ( with or without it's own attachments ) or not Moreover, I think it would make sense if the "rejected messege" contained information about size of rejected message and current mailbox space usage. Please, consider this in future development. with regards and respect to the tremendousness of Dovecot, -- malloc4k

[Dovecot] doveadm director status username != doveadm director status username@mailserver
by Joseba Torre 17 Jul '12

17 Jul '12

Hi, I've almost finished my new director based setup, but in the first test I discovered that imap and lmtp connections were not always being proxied to the same server. After some research now I think that the main problem is that in imap connections users connect as 'username' while lmtp connections are as 'username@mailserver'. In my current setup I receive mail via SMTP in my director servers (which are loadbalanced by a CISCO machine), and then they send them to dovecot running on localhost.

We don't use passdb in the directors because incoming mails have already been checked by postfix, and the final mail server need to check our ldap server for other values, so we check there.

[Dovecot] imapc: Restrict the number of connections
by René Neumann 17 Jul '12

17 Jul '12

Hi, I have managed to get an imapc connection to another server and bind its contents to only one account (via global ACL). The namespace itself is created as public, though it does not seem to make a difference for this use case (i.e., it does not matter, whether its type is 'public', 'shared', or 'private'). namespace { hidden = no list = children location = imapc: prefix = Gemeinsam. separator = . subscriptions = no type = public } One problem remains: Though there is only one account that is allowed to use this imapc-connection, each imap-process opens a connection to the imapc'd server. Is this caused directly by the imapc_*-definitions in the config? Or is there a way of restricting this to only the account which actually uses it. Used dovecot version: 2.1.8 Thanks, René

Dear Timo, Do you intend to introduce bcrypt into the built in password schemes? In lew of all these hacks lately many larger companies appear moving this way, we are looking at it too, but dovecot will then be the weakest link in the database security. So, are you planning on this and if so what sort of timeframe / version would you expect it to be in beta ? Nik

[Dovecot] incremental backups of maildir via rsync

17 Jul '12

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi folks, I would like to do incremental backups of the users' maildir directories to a dedicated backup host (using "rsync -SHa" and rsnapshot). Problem is: Dovecot bloats the incremental backup by changing the file names again and again. Is there some way to tell Dovecot to keep meta information separate from the file names? Any helpful comment would be highly appreciated.

[Dovecot] Last login datetime on accounts
by Robert Blayzor 16 Jul '12

16 Jul '12

I have searching for the best way to tell if a Dovecot user is idle by finding the last time they have logged in. Right now the best way I can tell is to do something like "touch" a file in the users homedir via a post login exec. This seems like a LOT of overhead, to accomplish such a simple task, especially if your doing a lot of dozens of logins per second. Is there an easier/better way? Is there a way to possibly tell Dovecot to refresh the mod time on an index file whenever the user successfully auths or to refresh a separate file in the homedir, ie: ~/.lastlogin (not ~/Maildir/.lastlogin as that would obviously cause some issues) Seems like something that would be far less overhead than calling a shell, execing another command, etc. I'm open to other ideas/alternatives if they are out there!

[Dovecot] Multi Server Exim/Dovecot and NFS
by Robert Blayzor 16 Jul '12

16 Jul '12

In reading the Dovecot NFS WIKI entry: http://wiki2.dovecot.org/NFS It mentions a FreeBSD NFS client caching bug. I believe that bug only exists pre-8.x ? It seems that a patch in the PR notes was MFC'd and made it into 8.x at some point. (at least I checked the source in 8.3 and it was there). So I assume that FreeBSD 8.x mitigates the issue? Maybe not? So our deployment is multi server Dovecot/Exim running on FreeBSD servers, frontended by a layer3 load balancing switch and a NetApp NFSv3 datastore. The only real concern we have right now is race conditions and file write contention on the Dovecot index files. Our original plan was to use Dovecot LMTP on the servers to deliver to the inbox, but that doesn't seem to be recommended as we'll have a number of servers all acting as primary MX for domains and delivering to the same set of mailboxes. So are the Dovecot dotlock file locking mechanisms not enough for multiple servers trying to write/access index files in Maildirs? If we have to deliver straight to the ~/Maildir/new out of Exim, that's fine, also. We're just wondering if there is a added benefit of actually using LMTP. (other than making sure the index are kept the most recent). The other concern we have is client mailbox access. While we can make sessions "sticky" from one IP so they hit the same server, it doesn't help with the person that checks their email via POP from their PC while having their mobile phone access it via IMAP. (obviously from different IP addresses). So I guess there is some possibly index file write contention there as well. (though hopefully this should be rare). I'm curious as to know others experiences with a similar deployment. TIA -- Robert Blayzor INOC, LLC rblayzor(a)inoc.net http://www.inoc.net/~rblayzor/

[Dovecot] ACL with MySQL dict => full table scans
by Roland Rosenfeld 16 Jul '12

16 Jul '12

Hi! I'm just installing ACL support on 2.1.6. When a user changes these ACLs, this results in a full table scan on the dictionary, that tells dovecot who shares with whom. Here's what queries I see when I run $ doveadm acl delete -u user1 shared/user2/folder user=user1 1: SELECT dummy,to_user,from_user FROM imap_acl_shares 2: SELECT dummy,from_user FROM imap_acl_anyone 3: BEGIN 4: DELETE FROM imap_acl_shares WHERE to_user = 'user1' AND from_user = 'user1' 5: INSERT INTO imap_acl_shares (dummy,to_user,from_user) VALUES ('1','user1','user1') ON DUPLICATE KEY UPDATE dummy='1' 6: DELETE FROM imap_acl_shares WHERE to_user = 'user2' AND from_user = 'user1' 7: INSERT INTO imap_acl_shares (dummy,to_user,from_user) VALUES ('1','user2','user1') ON DUPLICATE KEY UPDATE dummy='1' 8: COMMIT Line 2 is okay, since imap_acl_anyone is always empty (I'm not able to disable this query, otherwise dovecot spawns errors about a missing map, but I can live with this). Don't ask me what lines 4/5 are repeated in 6/7, but these use indexes and I can live with this. But what the hell is line 1? Why doesn't dovecot use a WHERE clause here with either to_user='user1', to_user='user2', from_user='user1', or from_user='user2'? All these WHERE clauses would use an index and speedup the query. Without the WHERE clause I expect 100000 or more results on our production system, which could slow down it massively. Here's my setup: /etc/dovecot/dovecot-dict-sql.conf: connect = host=foo dbname=mail user=imap password=hidden map { pattern = shared/shared-boxes/user/$to/$from table = imap_acl_shares value_field = dummy fields { from_user = $from to_user = $to } } map { pattern = shared/shared-boxes/anyone/$from table = imap_acl_anyone value_field = dummy fields { from_user = $from } } And dovecot -n: # 2.1.6: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-amd64 x86_64 Debian 6.0.5 auth_cache_negative_ttl = 5 mins auth_cache_size = 100 M auth_cache_ttl = 5 mins auth_default_realm = example.com auth_master_user_separator = * auth_mechanisms = plain login auth_verbose = yes dict { acl = mysql:/etc/dovecot/dovecot-dict-sql.conf } disable_plaintext_auth = no listen = * log_timestamp = "%Y-%m-%d %H:%M:%S " mail_fsync = always mail_gid = 999 mail_location = maildir:~/mail mail_plugins = acl quota mail_uid = 999 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 ihave imapflags mmap_disable = yes namespace { list = children location = maildir:%%h/mail:INDEX=~/mail/shared/%%u prefix = shared/%%u/ separator = / subscriptions = no type = shared } namespace inbox { inbox = yes location = prefix = separator = / type = private } passdb { args = /etc/dovecot/passwd.master driver = passwd-file master = yes pass = yes } passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } plugin { acl = vfile acl_shared_dict = proxy::acl quota = maildir sieve = ~/.dovecot.sieve sieve_dir = ~/mail/sieve sieve_extensions = +imapflags } protocols = imap pop3 sieve service auth { unix_listener auth-master { group = vmail mode = 0600 user = vmail } } service dict { unix_listener dict { group = vmail mode = 0600 user = vmail } } service imap { process_limit = 4000 } service managesieve-login { inet_listener sieve { port = 4190 } } service managesieve { process_limit = 100 } service pop3 { process_limit = 1000 } shutdown_clients = no ssl = no syslog_facility = local2 userdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } verbose_proctitle = yes protocol imap { mail_max_userip_connections = 10 mail_plugins = quota imap_quota acl imap_acl } protocol pop3 { mail_plugins = quota pop3_no_flag_updates = yes pop3_uidl_format = %v.%u } Tschoeeee Roland

[Dovecot] Issues with Plus addressing and detail part of subaddress.
by Sean Kamath 16 Jul '12

16 Jul '12

Hi all, So, it's been a while. I'm just ramping back up with Dovecot after a hiatus of a few years. I've been using it fine, complete with Sieve, for about a year, with little or no issues. I finally got around to setting up a second account, to start figuring out how I want to do some plus address filtering. In a nutshell, I want to put mail for foo+bar in foo's 'bar' folder. That's in the wiki. I did this: require ["fileinto", "envelope", "subaddress"]; if header :contains "subject" ["test"] { fileinto "Test"; } if envelope :detail "to" "test" { fileinto "test"; stop; } So, this fails miserably. No error message, nothing in the logs, no nothing. Yet, when I run sieve-test .dovecot.sieve /path/to/testmessage it works just fine. I even run sieve-test -e .dovecot.sieve /path/to/testmessage and it files it just fine into the folder. I tried adding some debug logging, but it looks like vnd.dovecot.debug isn't in my version. I searched the archives, and found a bit about adding (explicitly) the delimiter to the plugin section of 90-sieve.conf. So I did that. I'm running 2.0.13 of dovecot, and pigeonhole 0.2.3 on Solaris 10. Before I dive in and upgrade everything, am I missing something simple? The "test" bit works just fine (and in another account as well), so I think something's just not seeing the detail in subaddressing when mail is delivered (even though it works just fine with sieve-test). Thanks, Sean

[Dovecot] Migrating with dsync and INBOX.INBOX namespace issue

I'm working on migrating IMAP users from Mirapoint Message Servers to Dovecot servers. The Mirapoint IMAP server uses INBOX as a namespace for private mailboxes.

I'm running dovecot v1.2.9 postfix v2.7 on Ubuntu v10.4 Thanks, Nick. . . . . MU/Webcasting -- _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ . . . . . . . .

[Dovecot] imap-login: Panic: epoll_ctl(add, 6) failed: Invalid argument
by Angel L. Mateo 13 Jul '12

13 Jul '12

Hello, More problems (it seems that we won't be able to put our new servers in production). The problem now is that when we reach 1000 dovecot processes we have errors like: Jul 9 12:10:22 myotis31 dovecot: imap-login: Panic: epoll_ctl(add, 6) failed: Invalid argument Jul 9 12:10:22 myotis31 dovecot: imap-login: Fatal: master: service(imap-login): child 32251 killed with signal 6 (core dumps disabled) and server doesn't accept any new connection. Our servers are running in ubuntu 12.04 with kernel 3.2.0-24-generic kernel. I have found a similar problem at https://bugzilla.redhat.com/show_bug.cgi?id=681578 but it is for redhat kernel of series 2.6. Could be the same problem? Any pointer to this problem for ubuntu kernels? Or for generic 3.0 kernels? Any idea? -- Angel L.

[Dovecot] mail_log plugin logs UTF-8 mailbox name
by Ewald Dieterich 11 Jul '12

11 Jul '12

A small bug in the mail_log plugin: When I copy a mail from the inbox to a mailbox with special characters, the mailbox name is logged in UTF-8: [...] copy from INBOX: box=INBOX.Euro €, [...] I guess the name should be in mUTF-7, like it is done when I copy the other way round: [...] copy from Euro &IKw-: box=INBOX, [...]

[Dovecot] more dsync problems: Error: proxy client timed out
by Jeff Gustafson 11 Jul '12

11 Jul '12

Hi all, I'm using dsync for backups. I recently upgraded to 2.1.7 due to issues with dsync mirror/backups. 2.1.7 fixed the issue with the guid conflict, but now I'm seeing this error on a couple of mailboxes: Error: proxy client timed out (waiting for output stream to flush, 0 bytes left) If there are 0 bytes left, why is it trying to flush? I'm using this command to backup the mailbox: dsync -vo mail_home=/home/users/user%domain.com backup ssh vmail(a)10.1.2.2 dsync -o mail_home=/home/.incoming_mail_migrations/users/user%adomain.com Any ideas? ...Jeff

First, this sub discussion in this thread has been dealing strictly with mechanical storage, and that was intentional.

[Dovecot] recover .sieve plaintext from .sievec binary file
by Florin Andrei 10 Jul '12

10 Jul '12

Hi, I upgraded a server from an old Linux distribution to a much newer one. In the process, Dovecot got upgraded from v1 to v2. By mistake, I deleted the .sieve plaintext file with all the Sieve filters, but I still do have the .sievec compiled binary. Is there any way to dump the binary file back into plaintext format? Keep in mind, I'm running v2 now, and the binary was made on a v1 Dovecot server. Thanks. -- Florin Andrei http://florin.myip.org/

[Dovecot] configuring imap_stats

Hi, i'm trying to configure imap_stats like it's documented in the wiki: http://wiki2.dovecot.org/Statistics. But as soon as i activate the imap_stats plugin i get the following error message trying to login via imap: dovecot: imap: Error: Can't load plugin imap_stats_plugin: Plugin stats must be loaded also (you must set: mail_plugins=$mail_plugins stats) But the stats plugin is configured as you can see in the attached configurations. Also i can get statistics without the imap_stats enabled, but as far as i know only of the pop3 users. Kind regards Reinhard

[Dovecot] mailboxes missing after upgrade from 2.1.4 to 2.1.7
by Micah Anderson 09 Jul '12

09 Jul '12

Hi all, I mentioned this on the #dovecot irc channel, but I thought I would post here so I can provide more details. The basic problem is that when I upgraded from 2.1.4 to 2.1.7, some users no longer are able to see their folders in pine/alpine. The folders are actually there, and are subscribed (according to doveadm) and its possible to do operations on those folders, if you know the name (for example, opening the folder works fine if you know the name). When I downgrade to 2.1.4 again, the folders appear again, so its clearly something that changed between the two versions. I looked through the changelog, and found a few possibile culprits, I think pine/alpine use imapc, so that could be related: . imapc: Use imapc_list_prefix also for listing subscriptions . Fixed looking up parent mailbox name with different namespace vs. layout separators. . imapc: Don't list mailboxes that don't match list patterns. . layout=fs: Fixed listing mailboxes with prefix=INBOX/ . LIST with mailbox {} settings incorrectly set subscribed-flags. Here is my dovecot -n output: # OS: Linux 2.6.32-5-amd64 x86_64 Debian 6.0.5 auth_default_realm = example.net auth_verbose = yes default_process_limit = 256 default_vsz_limit = 512 M dict { expire = mysql:/etc/dovecot/dovecot-dict-sql.conf quota = mysql:/etc/dovecot/dovecot-dict-sql.conf } disable_plaintext_auth = no first_valid_gid = 8 first_valid_uid = 8 last_valid_gid = 8 last_valid_uid = 8 listen = * login_greeting = howdy, ready. mail_location = mdbox:~/mdbox:INDEX=/srv/dovecot_indexes/%d/%1n/%n mail_plugins = expire quota zlib stats maildir_very_dirty_syncs = yes namespace { inbox = yes location = prefix = separator = . } namespace { alias_for = hidden = yes inbox = no list = no location = prefix = INBOX. separator = . } passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } plugin { antispam_allow_append_to_spam = yes antispam_backend = pipe antispam_debug_target = syslog antispam_pipe_program = /usr/local/bin/train_spam antispam_pipe_program_args = -d;10.0.1.109 antispam_pipe_program_notspam_arg = ham antispam_pipe_program_spam_arg = spam antispam_pipe_tmpdir = /var/tmp antispam_signature = X-Spam-Flag antispam_signature_missing = error antispam_spam_pattern_ignorecase = SPAM antispam_trash_pattern = trash;Trash;Deleted * expire = Trash expire2 = Trash/* expire3 = Spam expire_dict = proxy::expire quota = dict:Your mail quota::proxy::quota quota_rule = *:bytes=100663296 quota_rule2 = Trash:bytes=+20%% quota_rule3 = Spam:bytes=+10%% quota_rule4 = INBOX.Trash:bytes=+20%% quota_rule5 = INBOX.Spam:bytes=+10%% quota_rule6 = INBOX.restored_from_backups:bytes=+500%% sieve = ~/.dovecot.sieve sieve_after = /var/lib/dovecot/sieve/after.sieve sieve_before = /var/lib/dovecot/sieve/default.sieve sieve_dir = ~/sieve stats_refresh = 30 secs stats_track_cmds = yes zlib_save = gz zlib_save_level = 6 } postmaster_address = postmaster(a)example.net protocols = " imap pop3" service anvil { unix_listener anvil { group = dovecot mode = 0660 user = root } } service auth { unix_listener auth-userdb { group = mail mode = 0600 user = mail } } service dict { unix_listener dict { group = mail mode = 0600 user = mail } } service imap-login { process_min_avail = 10 service_count = 0 vsz_limit = 512 M } service imap-postlogin { executable = script-login /usr/local/sbin/postlogin_imap } service imap { executable = imap imap-postlogin process_limit = 2048 } service pop3-login { process_min_avail = 10 service_count = 0 vsz_limit = 512 M } service pop3-postlogin { executable = script-login /usr/local/sbin/postlogin_pop } service pop3 { executable = pop3 pop3-postlogin } service stats { fifo_listener stats-mail { mode = 0600 user = mail } } ssl_cert = </etc/certs/wildcard/cert.pem ssl_cipher_list = HIGH:-ADH:-aNULL ssl_key = </etc/certs/wildcard/key.pem userdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } verbose_proctitle = yes protocol lda { mail_plugins = expire quota zlib stats sieve plugin { quota_exceeded_message = Sorry, your message cannot be delivered to that person because their mailbox is full.

[Dovecot] I changed the separator from . to / and it still seems to work.
by Hans de Groot 06 Jul '12

06 Jul '12

Hello, Just as an experiment I changed the separator from . to / restarted dovecot (v2.1.1). When adding an existing account with lots of mail folders to thunderbird everything still seems to work. My directory layout is like this: .Info.mailinglists .Info.mailinglists.Horde .Info.mailinglists.modperl .Info.mailinglists.PDNS .Info.mailinglists.Sogo .Info.mailinglists.tinc .Info.mailinglists.Zabbix I added a new folder to the horde mailing using thunderbird list and got an extra folder .Info.mailinglists.Horde.testinhorde Does this mean the separator has nothing to do with the . in the directory names and I am safe to switch saparators without having to do anything else?

[Dovecot] Dovecot v2 shared mailboxes , a . separator and complete emailaddress as username.
by Hans de Groot 06 Jul '12

06 Jul '12

Hello, I've been trying to get shared mailboxes to work and got stuck. I tried lots of examples made the shared dict but the shared mail boxes never showed up. I am using the . separator and I think this the problem. I changed it to a / separator and now I could see my shared mailboxes. Checking the maillog in debug mode I saw a few failed login attempts between the succesful logins. The weird thing is that the username was changed, instead of hansg(a)debushalte.nl the login was hansg@debushalte without the .nl part and that user is not in my database. So I suspect that dovecot splits the shared path based hansg(a)debushalte.nl shares mailboxes with dean(a)debushalte.nl below a few lines from the log: Debug: Namespace : type=shared, prefix=INBOX.shared.%u., sep=., inbox=no, hidden=no, list=yes, subscriptions=no location=maildir:%h/mail:INDEX=/mail/debushalte.nl/dean/mail/shared.%u Debug: shared: Tried to access mails of nonexistent user hansg@debushalte Debug: Namespace INBOX.shared.hansg@debushalte.: Creating storage despite: Root mail directory doesn't exist Is there a work arround for this? I really like to keep using '.' as a seperator so I do not have to change all the existing mailboxes. If I do rename and move all existing mailboxes the '/' separator way and of course change the separator in the namespaces would my users notice this? (ie would they have to change something in their mail clients?) Regards Hans

[Dovecot] dovecot and nfs readdir vs readdirplus operations
by Angel L. Mateo 06 Jul '12

06 Jul '12

Hello, We are having performance problems trying to migrate our pop/imap servers to a new version. Our old servers are 4 debian lenny with 5GB of RAM running of XenServer VMs with kernel 2.6.32-4-amd64 and dovecot 1.1.16. New servers are 4 ubuntu 12.04 with dovecot 2.1.5 running on vmware vm with 6 cores and 16GB of RAM and kernel 3.2.0-24-generic. On both server we are using nfs 3 with same configuration (regardless of internal kernel differences, but we have no customized any of them, we are using vanilla kernels with default configurations). The problem we have is that new servers have performance problems. Even when have a small part of our total users (about 25%) directed to the new farm, performance is very poor, even useless. Looking for NFS problems, we have found a lot of differences in nfs operations. For example, this is the nfsstat of one of a new servers at this moment: myotis21:~# nfsstat Client rpc stats: calls retrans authrefrsh 414528349 885 37 Client nfs v3: null getattr setattr lookup access readlink 0 0% 95673837 23% 3961938 0% 89586364 21% 110097351 26% 2930961 0% read write create mkdir symlink mknod 20009850 4% 6065319 1% 3757720 0% 1557 0% 0 0% 0 0% remove rmdir rename link readdir readdirplus 6378134 1% 281 0% 2602358 0% 555097 0% 53126619 12% 15615402 3% fsstat fsinfo pathconf commit 113256 0% 26152 0% 0 0% 4026151 0% and this is the same on one of the new ones: amateo_adm@myotis31:~$ nfsstat Server rpc stats: calls badcalls badclnt badauth xdrcall 0 0 0 0 0 Client rpc stats: calls retrans authrefrsh 178040318 675 178040800 Client nfs v3: null getattr setattr lookup access readlink 0 0% 24350345 13% 5045924 2% 10939469 6% 30185146 16% 142865 0% read write create mkdir symlink mknod 8818016 4% 6058614 3% 2877653 1% 420 0% 0 0% 0 0% remove rmdir rename link readdir readdirplus 2842562 1% 69 0% 2961239 1% 634038 0% 0 0% 82921863 46% fsstat fsinfo pathconf commit 70861 0% 18754 0% 9377 0% 152702 0% Although nfs configuration is the same, there are a lot of differences on readdir vs readdirplus nfs operations. In fact, in the old one we have 12% readdir operations and 3% of readdirplus. And in the new one we have 46% of readdirplus and no readdir operations. Although readdirplus is supposed to be an optimization in nfs3, in situations when you have big directories and uses just a few entries of these directories it could be worse. So we think if this could be the problem (or one of them). Any idea of this difference? And if this difference could be significative? PS: I have attached doveconf -n of the new server. -- Angel L.

[Dovecot] Dovecot mailstorage migration uppon logging / delivery with dsync
by Xavier Beaudouin 05 Jul '12

05 Jul '12

Hi there, I have a pretty standard setup with "simple" dovecot 2,0 configuration (eg /var/mailboxes on NFS with old netapp) and local ldap directory and Maildir. I wanted to find a good way to migrate from NFS old netapp to NFS new server (this one is not a netapp !). There 3 kind way (according to my own experience) - rsync old spool to new spool being patient stop services and then doing last rsync and mount /var/mailboxes mount point from old netapp to new nfs server). - doing imap_login (and other stuff like this) doing an rsync per box AFTER doing the first rsync with all boxes... - using dsync to fetch the maildir stuff from old server to new one, doing a simple flag, and doing "au fil de l'eau" migration. The last one seems to me a good idea, but I cannot figure host to make this correctly. Any hints or do someone here has already done this kind of stuff? Kind regards, -- Xavier Beaudouin

[Dovecot] Migration Question
by Peter Fraser 05 Jul '12

05 Jul '12

Hi all I got a shiny new server and I want to install the latest and greatest of everything on it. The old server has dovecot-1.2.17 working with postfix-2.8.4,1, dovecot quotas, sieve etc. My question is: Would it work of I installed dovecot 2 on this server along with everything I want and just copy the /home/virtualmail directory where all the user mail directories are? I use the Maildir format by the way.

[Dovecot] Outlook 2010 very slow when using IMAP - are there any tweaks?
by Kaya Saman 03 Jul '12

03 Jul '12

Hi, though this is a bit of a side question, has anybody had an issue while running Outlook 2010 with Dovecot? The reason why I am asking is that I have setup a Dovecot 2.1.7 server on FreeBSD which works fantastically with Thunderbird but Outlook seems to be twice as slow in transferring information across?? # dovecot -n # 2.1.7: /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 8.2-RELEASE amd64 auth_debug = yes auth_mechanisms = plain ntlm login auth_use_winbind = yes auth_username_format = %n auth_verbose = yes auth_winbind_helper_path = /usr/local/bin/ntlm_auth disable_plaintext_auth = no info_log_path = /var/log/dovecot-info.log log_path = /var/log/dovecot.log mail_gid = mail_user mail_home = /mail/AD_Mail/%Ld/%Ln mail_location = maildir:~/Maildir mail_uid = mail_user passdb { args = failure_show_msg=yes driver = pam } pop3_fast_size_lookups = yes pop3_lock_session = yes pop3_no_flag_updates = yes protocols = imap pop3 ssl = no userdb { driver = static } Since (like most corporate organizations out there) we solely run Outlook coupled to Exchange, this excersize was meant to be a way of getting rid of PST files. We don't run out own Exchange however, and don't have any control over it either. My workaround was to simply use the Outlook GUI space to transfer emails between Exchange and Dovecot running the IMAPv4 protocol. For whatever reason Outlook is being really garbage about dealing with stuff and since I don't know Outlook or MS products very well (being your typical average OpenSource guy) I was wondering if there were any tweaks that could be made within Outlook to speed it up or in Dovecot to work better with Outlook? I guess one could get sidetracked into the argument of mdbox vs. Maildir from my config however, Thunderbird is really fast and transfers large amounts of data really easily. Reaches round 130Mbps using nload performance grapher, while Outlook only manages ~50kbps but spikes at 2-3Mbps on occassion. Can anyone offer any guidence or assistance in this matter?? Actually wherever I run Dovecot, including my servers at home, it is fast and reliable. Yes I know MS is the polar opposite of anything worth using however, my company won't change and I'm stuck banging my head against the wall while trying to get MS to interface with ANYTHING.....

[Dovecot] Problem with 'doveadm mailbox status -t' reporting cumulative vsizes after upgrading from v2.0.16 to v2.1.7
by Jase Thew 03 Jul '12

03 Jul '12

Hi, I upgraded from Dovecot v2.0.16 to v2.1.7 over night and I noticed this morning that one of my daily reports which lists summarised mailbox sizes per user has started listing nonsense for vsizes. The reporting script at its core calls : doveadm -f flow mailbox status -A -t 'messages vsize' '*' It appears that Dovecot 2.1.7 is not resetting the vsize after collating the sum total of mailboxes sizes for each user, so that vsize just constantly increases as it iterates over each user. Eg: # doveadm -f flow mailbox status -A -t 'messages vsize' '*' accounts(a)example.com messages=1 vsize=759 adam(a)example.com messages=0 vsize=759 amy(a)example.com messages=24 vsize=51699697 andy(a)example.com messages=5446 vsize=3220940815 anna(a)example.com messages=50 vsize=3224035563 careers(a)example.com messages=1 vsize=3224036311 craig(a)example.com messages=2471 vsize=4421343199 creative(a)example.com messages=189 vsize=4426884182 david(a)example.com messages=8 vsize=4440729729 davidw(a)example.com messages=0 vsize=4440729729 enquiries(a)example.com messages=1 vsize=4440730491 gemma(a)example.com messages=4109 vsize=6349098844 gin(a)example.com messages=86 vsize=6392599904 holly(a)example.com messages=2000 vsize=7200342663 ian(a)example.com messages=0 vsize=7200342663 info(a)example.com messages=4 vsize=7200558689 jackie(a)example.com messages=2 vsize=7200721146 jade(a)example.com messages=137 vsize=7210548548 jake(a)example.com messages=16667 vsize=15260532446 katie(a)example.com messages=1 vsize=15260533375 mark(a)example.com messages=0 vsize=15260533375 mike.a(a)example.com messages=9 vsize=15261474205 mike.s(a)example.com messages=296 vsize=15314352543 mike(a)example.com messages=6357 vsize=20631446344 nick(a)example.com messages=1184 vsize=21038046728 social(a)example.com messages=65 vsize=21038935461 will(a)example.com messages=85 vsize=21057572390 [SNIP] The same occurs with -u '*(a)example.com' in place of -A, and also for 'all' in place of 'messages vsize'. Is this expected behaviour in 2.1.x compared to 2.0.x, or have I stumbled upon a bug? Regards, Jase Thew.

[Dovecot] Dovecot shared library to replace libc-client
by Asheesh Laroia 03 Jul '12

03 Jul '12

Hi all Dovecotters, Lots of programs (e.g, PHP) link to a library called c-client, which is a derivative of the original IMAP implementation, UW IMAP. (For those new to UW IMAP, read here: http://www.washington.edu/imap/ ) UW IMAP is not in as much of active development as it used to be, so I am curious: I see there is a dovecot shared library. I haven't looked into the details, but here are things I'm interested in: 1. Replacing libc-client's use as a client library In Debian, for example, you can search for packages that depend on this library as a client. It looks like this: $ ~ apt-cache rdepends libc-client2007e libc-client2007e Reverse Depends: uw-mailutils uw-imapd libc-client2007e-dev ipopd prayer php5-imap mailsync libmail-cclient-perl asterisk aolserver4-nsimap uw-mailutils libc-client2007e-dev prayer php5-imap mailsync libmail-cclient-perl asterisk-voicemail-imapstorage Let's say, hypothetically, we wanted to switch php5-imap to using Dovecot where it currently uses libc-client. I envision creating libdovecot-c-client-alike that is a set of headers and a library that is API-compatible with (at least a subset of) c-client. You can call that a "compatibility shim." Then e.g. php5-imap could be given the path to those headers and the corresponding libdovecot-c-client-alike library, and when it thinks it is linking to c-client, it could instead link to the libdovecot-c-client-alike. This might be convenient if you want to limit how much of a public API is presented by the current "dovecot.so" that gets installed in e.g. /usr/lib/dovecot/. The compatiblity shim could have a small API, and if you don't want provide ABI guarantees within dovecot.so, the shim could dlopen() dovecot.so rather than link to it. 2. Use of Dovecot shared library within alpine, embedding the imapd Right now, the mail client "alpine" embeds a copy of the UW IMAP source. It uses this when accessing local mail spools, for example. If Dovecot's IMAPd were available as a shared library, perhaps with a c-client-like API, (although not necessarily -- it would be feasible to upgrade alpine to a different API), then alpine could use Dovecot's mail drivers directly. So, those two are the dream. Timo and others, what are your thoughts? Thanks for reading this far! -- Asheesh. P.S. The radical request #2 would be an excellent, decisive way to end a sad thread in the Debian bug tracker about Alpine + Maildir: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=405762 .

[Dovecot] v2.1.8 released
by Timo Sirainen 03 Jul '12

03 Jul '12

http://dovecot.org/releases/2.1/dovecot-2.1.8.tar.gz http://dovecot.org/releases/2.1/dovecot-2.1.8.tar.gz.sig Most importantly fixes a pretty bad behavior of sending mailbox names as UTF-8 instead of mUTF-7 as required by IMAP RFC. I'm surprised nobody hadn't noticed this in v2.1.x tree before yesterday. I guess some clients might have translated the name to UTF-8 anyway and not noticed it, while others would have silently ignored the problem of not seeing STATUS updates. + pop3c: Added pop3c_master_user setting. - imap: Mailbox names were accidentally sent as UTF-8 instead of mUTF-7 in previous v2.1.x releases for STATUS, MYRIGHTS and GETQUOTAROOT commands. - lmtp proxy: Don't timeout connections too early when mail has a lot of RCPT TOs. - director: Don't crash if the director is working alone. - shared mailboxes: Avoid doing "@domain" userdb lookups. - doveadm: Fixed crash with proxying some commands. - fts-squat: Fixed handling multiple SEARCH parameters. - imapc: Fixed a crash when message had more than 8 keywords. - imapc: Don't crash on APPEND/COPY if server doesn't support UIDPLUS.

[Dovecot] Additional passdb result status
by Jürgen Pabel 03 Jul '12

03 Jul '12

Dear Dovecot-Team, I am implementing a plugin (for the pop3/imap process) that requires some data to provided from the authentication phase (a derivative of the password). For that, I have now implemented a passdb plugin that generates this data and I would like to "pass" this data down to the mail process (pop3/imap) via extra_fields in the reply of the authentication. The general idea is that my custom passdb plugin calculates the data, sets the extra_field and returns some error (authentication was not successful) so that the "real" passdb backend can be invoked to "really" validate the authentication data. However, in auth_request_handle_passdb_callback() the extra_fields are reseted unless the return code is PASSDB_RESULT_USER_DISABLED. But if that return code is used then any following passdb's aren't invoked any more - which makes sense with respect to user authenticiation. I would therefore like to propose that some IGNORE/CONTINUE-status to be introduced in auth/passdb.h, that would be handled in that extra_fields and possible other values are not reseted in order to allow such propagation of data from authentication process down to the mail process (which could be extracted from the reply string by parsing it). As a further implementation alternative (to the parsing of the reply string), I also propose that some new "environment" item be introduced (in auth_request) in order to allow such data passing in a generic manner. I hope you consider my proposal to be reasonable. If desired, I could implement this myself and provide a patch for merging (based on 2.0.x). If my proposal is generally unfavored, it would be great if any alternative approaches for my situation were suggested. Thanks. Regards, Jürgen PS: please reply to my e-mail (or CC me), as I have not subscribed to the dovecot list

[Dovecot] userdb errors after upgrading to 2.1
by André Rodier 03 Jul '12

03 Jul '12

Hello everybody, I am running debian wheezy for development and test, and I recently upgrade to dovecot 2.1.7 I am using LDAP lookups, and virtual users with the same UID/GID. Everything was working fine before, but now, I have this error when I try to send an email to a local account: -------------------------------------------------------- Jun 26 15:46:52 lapetus dovecot: lmtp(24518): Error: user user.test(a)indienet.com: Auth USER lookup failed Jun 26 15:46:52 lapetus dovecot: auth: Error: userdb(user.test(a)indienet.com,127.0.0.1): client doesn't have lookup permissions for this user: userdb reply doesn't contain uid (change userdb socket -------------------------------------------------------- However, even if I set the permissions to 0666, I still have the same error. Can you point me in the right direction to fix this, please? Kind regards, André Rodier

[Dovecot] Setting up mixed mbox and maildir
by Jonathan Ryshpan 03 Jul '12

03 Jul '12

I'm trying to set up a dovecot server for which mail arrives in an mbox, and mail is stored in a maildir. The wiki (see http://wiki.dovecot.org/Namespaces) refers to this as "Mixed mbox and Maildir". It advises handling this situation by creating two namespaces: one for the mbox and the other for the maildir. Each of these namespaces starts with namespace private { On the other hand the sample configuration in the documentation puts inbox in a namespace starting with: namespace inbox { # Namespace type: private, shared or public #type = private It appears that there has been a change in the configuration syntax after the wiki was written, and that the word following namespace no longer gives a property of the namespace, but rather its name. Is this correct? In any case, how should the configuration be modified to handle mixed mailboxes? Thanks - jon

[Dovecot] Proxy config help please
by Zac Israel 03 Jul '12

Hello, I am new to dovecot and I am initially trying to setup a basic imap proxy with password forwarding, I can start the dovecot service, connect and give it my password, and that is where I hang. My config is: root@imap-test:/etc/dovecot# doveconf -n # 2.0.19: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-24-generic x86_64 Ubuntu 12.04 LTS auth_debug = yes auth_verbose = yes debug_log_path = syslog first_valid_uid = 100 imap_capability = CAPABILITY IMAP4rev1 ACL BINARY CATENATE CHILDREN CONDSTORE ENABLE ESEARCH ESORT I18NLEVEL=1 ID IDLE LIST-EXTENDED LIST-STATUS LITERAL+ LOGIN-REFERRALS MULTIAPPEND NAMESPACE QRESYNC QUOTA RIGHTS=ektx SASL-IR SEARCHRES SORT THREAD=ORDEREDSUBJECT UIDPLUS UNSELECT WITHIN XLIST last_valid_uid = 200 mail_debug = yes mail_gid = 107 mail_uid = 107 passdb { args = proxy=proxy_always nopassword=y host=172.16.0.13 port=143 proxy_timeout=5 starttls=y ssl=any-cert driver = static } protocols = imap service imap-login { inet_listener imap { address = * port = 143 } } ssl = required ssl_cert = </etc/courier/imapd.pem ssl_key = </etc/courier/imapd.pem verbose_ssl = yes The system at 172.16.0.13 is a zimbra proxy. I can see in the logs that it initially complains about my ssl cert, and if I remove ssl=any-cert it fails because my cert is self signed, so I know it is talking to the proxy and doing starttls which is a requirement of zimbra. Unfortunately I have not found a way to see the full exchange between dovecot and my zimbra proxy other than tcp dump, which just shows a small packet exchange. Please let me know if I can provide any other information and thanks in advance for any help. -Zac

[Dovecot] Dovecot 2.1 stable packages for Debian?
by Krzysztof Trybowski 02 Jul '12

02 Jul '12

Hello all, it is strange, but Dovecot 2.x still didn't make it into Debian (not even backports). It exists in testing, but that's still a long wait. OTOH there are official packages built every day (referenced from the download page). This puzzles me: why isn't there a build created from each stable, released version of Dovecot, so that users of Debian Stable could benefit from the new version, and run it on production environment? Could you (I mean — the Dovecot team) provide such packages? This wouldn't require any major amount of work, since you already have daily builds produced. You would just have to run that building system once per each released version and keep it available for download. The reason for this is relatively simple: I'm about to implement a new mail server, and I'd like to keep to Debian Stable while using Dovecot 2.x. This will make future updates much easier, as I won't have to face 1.2 -> 2.0 migration on a production system. Regards, KT

Hello! somewhere in maillist I've seen RAID1+md concat+XFS being promoted as mailstorage. Does anybody in here actually use this setup? I've decided to give it a try, but ended up with not being able to recover any data off survived pairs from linear array when _the_first of raid1 pairs got down. thanks!

[Dovecot] [PATCH] GSSAPI authorization and virtual users
by Sam Morris 02 Jul '12

02 Jul '12

The attached patch makes it possible for Kerberos principals to be associated with a password database entry by adding a new "k5principals" passdb setting. A client that successfully authenticates using GSSAPI will be able to log in as any user who has been associated with the client's Kerberos principal. This means that users can now use their Kerberos identities to access virtual mail accounts. The patch definitely needs review by someone familiar with Dovecot. It works for me on a small test installation using the passwd-file backend. Things that should probably be improved: 1. The list of authorized principals is stored in struct auth_request. I would prefer to store it in struct gssapi_auth_request, but auth-request.c does not know about structs that are specific to the different authentication plugins. This could be fixed in a more general way by adding a new function to struct mech_module to allow authplugins to read fields during passdb lookups. 2. The gssapi authplugin now does a credential lookup in order to trigger parsing of the k5principals setting. In order for this to work, auth_request_set_username is now called before mech_gssapi_userok. AFAICT the only impact of this is that messages logged by this function (and the functions it calls) will now use the name of the virtual account. 3. The credentials lookup triggers an info log message saying that credentials for GSSAPI were requested, "but we have only (e.g.) MD5-CRYPT". The authplugin doesn't actually want the credential, but I think that the only way the authplugin can trigger a passdb lookup is by requesting it. 4. The final part of the code in mech_gssapi_unwrap was moved to the callback that's triggered when the credentials lookup is complete. The code still needs access to the GSSAPI data, so the buffer pointer & length are now stored in struct gssapi_auth_request, making the inbuf parameter to the mech_gssapi_{sec_context,wrap,unwrap} functions superfluous. The parameters should be removed. 5. The k5principals list won't be processed on Solaris. The code added to the end of mech_gssapi_krb5_userok would have to be moved to a separate function and then be called from the Solaris code. 6. GCC tells me about assignment to incompatible pointer types in the code that iterates through gssapi_k5principals. I must be missing something. The patch is licensed under the MIT license. Please let me know what you think. -- Sam Morris <sam(a)robots.org.uk>

[Dovecot] UTF-8 mailbox name STATUS response
by Ewald Dieterich 02 Jul '12

02 Jul '12

STATUS in Dovecot 2.1.7 returns the UTF-8 decoded folder name in a string literal: . CREATE "INBOX.Euro &IKw-" . OK Create completed. . LIST "" "INBOX.Euro &IKw-" * LIST (\HasNoChildren) "." "INBOX.Euro &IKw-" . STATUS "INBOX.Euro &IKw-" (MESSAGES) * STATUS {14} INBOX.Euro € (MESSAGES 0) . OK Status completed. Is this intended? My Perl script based on Mail::IMAPTalk doesn't like it and I wonder if there are other clients that don't cope with it.

[Dovecot] lmtp proxy timeout while waiting for reply to DATA reply
by Daniel Parthey 02 Jul '12

02 Jul '12

Hi, we are experiencing similar sporadic data timeout issues with dovecot 2.0.20 as in http://dovecot.org/pipermail/dovecot/2011-June/059807.html at least once a week. Some mails get temporarily deferred in the postfix queue since dovecot director lmtp refuses them and the mails are delivered at a later time. The problem applies to mails delivered to single users as well as distribution lists where the mails gets delivered to several mailboxes by postfix. The postfix log shows the following output: postfix.log.7.gz:Apr 21 18:48:46 10.129.3.233 postfix/lmtp[15868]: 88062C08E: to=<username(a)example.org>, orig_to=<username(a)example.org>, relay=127.0.0.1[127.0.0.1]:20024, delay=35, delays=5.4/0.01/0/30, dsn=4.4.0, status=deferred (host 127.0.0.1[127.0.0.1] said: 451 4.4.0 Remote server not answering (timeout while waiting for reply to DATA reply) (in reply to end of DATA command)) The dovecot.log (mailbox and director log there via syslog) shows the following output: Apr 21 18:46:53 10.129.3.233 dovecot: lmtp(15869): Debug: none: root=, index=, control=, inbox=, alt= Apr 21 18:46:53 10.129.3.233 dovecot: lmtp(15869): Connect from 127.0.0.1 Apr 21 18:46:53 10.129.3.233 dovecot: lmtp(15869): Debug: auth input: user=username(a)example.org proxy port=19024 host=10.129.3.190 proxy_refresh=450 Apr 21 18:46:53 10.129.3.233 dovecot: lmtp(15869): Disconnect from 127.0.0.1: Client quit (in reset) Apr 21 18:47:29 10.129.3.233 dovecot: lmtp(15869): Debug: none: root=, index=, control=, inbox=, alt= Apr 21 18:47:29 10.129.3.233 dovecot: lmtp(15869): Connect from 127.0.0.1 Apr 21 18:47:29 10.129.3.233 dovecot: lmtp(15869): Debug: auth input: user=username(a)example.org proxy port=19024 host=10.129.3.190 proxy_refresh=450 Apr 21 18:47:29 10.129.3.233 dovecot: lmtp(15869): Disconnect from 127.0.0.1: Client quit (in reset) Apr 21 18:48:15 10.129.3.233 dovecot: lmtp(15869): Debug: none: root=, index=, control=, inbox=, alt= Apr 21 18:48:15 10.129.3.233 dovecot: lmtp(15869): Connect from 127.0.0.1 Apr 21 18:48:15 10.129.3.233 dovecot: lmtp(15869): Debug: auth input: user=username(a)example.org proxy port=19024 host=10.129.3.190 proxy_refresh=450 Apr 21 18:48:46 10.129.3.233 dovecot: lmtp(15869): Disconnect from 127.0.0.1: Client quit (in reset) One cannot identify the lmtp log origin from the log_format prefixes, but it seems that the "lmtp($PID)" log originated from the director, since proxy port 19024 is mentioned in the logs, which is our dovecot mailbox backend. Config for dovecot (mailbox) and director (proxy) is attached. mail_debug is yes for both dovecot and director. How can we find out more information? Shall I apply the following patches from http://dovecot.org/pipermail/dovecot/2011-June/059987.html or are they already included with version 2.0.20? Regards, Daniel

[Dovecot] director directing to wrong server (sometimes)
by Angel L. Mateo 02 Jul '12

02 Jul '12

Hello, I have discovered a strange behaviour with director proxying... I have a user, its assigned server is 155.54.211.164.

[Dovecot] Config off by a nuance or a gross?
by Michael Brian Bentley 01 Jul '12

01 Jul '12

Hi, I am trying to establish an IMAP mail service accessible using a current Thunderbird on a laptop. I used Macports to install Dovecot2 (2.1.5) on an older Snow Leopard Mac mini with Intel Core Duo (specifically a Macmini1,1). My goal is to be able to run sieve under dovecot2 and offload the email triage from my work laptop to the little mail server. Mail appears to show up on the server just fine. I'm having trouble getting Tbird to log in and access properly. Because there are so many components in play (Tbird, pam, Dovecot2, macports, OS X Snow Leopard 10.6.8) (dovecot by itself seems to have quite a few settings), it is hard to tell what bit is out of whack. The message I get from Tbird 13.0.1 for OS X (on Lion) is: Alert: The IMAP server bentley on TheMini does not support the selected authentication method. Please change the 'Authentication method' in the 'Account Settings | Server settings'. When I set up the account, Tbird's automatic configuration invents a fake mail service based on my domain name, but appears to configure things sensibly once I switch to the manual configuration and fill in the relevant IP information. It does not appear to care whether it has a password or not. When I set up the account manually on TBird, I let it set up as: IMAP (ipv4)xx.xxx.xx.xx Port: 143 Connection security: None Authentication method: Password, transmitted insecurely SMTP xxxxxxxx.com Port: 587 The dovecot.conf tree includes these: passdb { driver = pam } userdb { driver = passwd } default_login_user = _dovenull default_internal_user = _dovecot service imap-login { executable = /opt/local/libexec/dovecot/imap-login inet_listener imap { address = * port = 143 } } service imap { executable=/opt/local/libexec/dovecot/imap process_limit = 1024 } service lmtp { unix_listener lmtp { } } Issuing the command: dovecot --build-options produces: Build options: ioloop=kqueue notify=kqueue ipv6 openssl io_block_size=8192 Mail storages: shared mdbox sdbox maildir mbox cydir imapc pop3c raw SQL drivers: Passdb: checkpassword pam passwd passwd-file Userdb: checkpassword passwd prefetch passwd-file The /etc/pam.d/dovecot file contains: # pop3, imap, smtp : auth account password session auth required pam_opendirectory.so account required pam_permit.so password required pam_deny.so session required pam_permit.so Dovecot provides the following debug messages on the console when I add args = failure_show_msg=yes to passdb in the relevant dovecot conf file: Jul 1 11:12:38 xx-xxx-xx-xx-nerewhon dovecot[3871]: auth: Debug:auth client connected (pid=5047) Jul 1 11:12:40 xx-xxx-xx-xx-nerewhon dovecot[3871]: imap-login: Disconnected (no auth attempts in 2 secs): user=<>, rip=192.168.xx.xx, lip=xx.xxx.xx.xx I recently discovered doveadm and used it with: doveadm config to create what I think is the current dovecot.conf file. I hesitate to inflict that on the list without being told, "yeah, we need that," there may be digest subscribers out there... I also see these messages show up; they appear unrelated to what I do with Tbird: Jul 1 11:37:33 xx-xxx-xx-xx-nerewhon dovecot[3871]: auth: Debug: Loading modules from directory: /opt/local/lib/dovecot/auth auth: Debug: auth client connected (pid=5094) auth: Debug: client in: AUTH 1 PLAIN service=imap secured lip=127.0.0.1 rip=127.0.0.1 lport=143 rport=49774 auth: Debug: client out: CONT 1 auth: Debug: client in: CONT 1 AGJlbnRsZXkAZ3IxbmNo auth-worker(5100): Debug: Loading modules from directory: /opt/local/lib/dovecot/auth auth-worker(5100): Debug: pam(bentley,127.0.0.1): lookup service=dovecot auth-worker(5100): Debug: pam(bentley,127.0.0.1): #1/1 style=1 msg=Password: auth-worker(5100): pam(bentley,127.0.0.1): pam_authenticate() failed: authentication error (password mismatch?)

[Dovecot] ot: trying to understand log entries, etc
by Voytek Eymont 01 Jul '12

totally of, I'm trying to understand what's happening, aka, 'how does email works' ? I have Dovecot 1.x, all works fine I noticed in the logs failed access from no-longer-hosted account/user, physical account deleted/removed, most likely from user's BBerry, every ~15 minutes: from /var/log/maillog --- Jun 24 07:31:25 dovecot: imap-login: Disconnected: Inactivity (auth failed, 1 attempts): user=<vvv@tld>, method=PLAIN, rip=101.222.222.222, lip=111.111.111.111 --- I recreated account/physical path /var/mail/.../tld/vvv@tld I logged in with webmail, all works, webmail logged out I physically copied some emails (from another account) to physical path ../../tld/vvv@tld/new after a while, I see the email files NO LONGER in ../../../new BUT now in ../../tld/vvv@tld/cur Q: that means the email was accessed, doesn't it ? BUT, I don't see any more access in the /var/log/maillog, not failed, not OK I did see one, after I recreated account Jun 30 20:01:53 dovecot: IMAP(vvv@tld): Disconnected: Logged out bytes=32/666 NONE since, but email files move from new to cur ?? if I observe email files moving from 'new' to 'cur' shouldn't I see some action logged in /var/log/maillog to correspond ? perplexed.... -- Voytek

Log message "lda(rolf)" looks like this happens. To summarize, I think LMTP will be the easiest way to fix the permission problems. Otherwise you would need to fiddle out how to prevent dovecot lda from switching to group additional group "mail", since unprivileged user "rolf" is not allowed to do that.

[Dovecot] how to announce shared folders to clients using non-default mail prefix
by Tom Lieuallen 30 Jun '12

30 Jun '12

We're using dovecot 2.1.3 and I've been doing some testing with 2.1.7. We have shared mail (maildir) folders working along with our default mbox mailboxes. Our problem is trying to get this to work in a reasonable fashion with our iPhone or iPad mail.app clients. It's well known that they don't honor the subscription list; they show all available mail folders and do not collapse trees of folders. I have 381 folders in directories under mail. Normal clients are fine, but this is unmanageable in IOS. What we have been doing is changing the mail prefix for the iPhone to a subfolder, then using soft links to point to the most commonly used folders we use. This works, but when one changes the mail prefix, any shared folders are not presented. I'm suspicious that this is a design decision. If there is some way to make it work, I'd be very grateful. Note the two 'sharedimap' folders listed in the first 'list'. Note that if I change the prefix for that shared namespace to 'iphonemail/', it does present my shared folders as well as anything in a personal iphonemail directory. However, 'select' didn't work with the personal folders. My guess is it's mostly due to the difference in mail formats between the two (mbox & maildir). But, it does show that somewhere in the code it's checking the mail prefix against namespaces and not displaying shared folders in non-default prefixes. I wish this were a configurable option. thank you Tom Lieuallen Oregon State University . list "" * * LIST (\Noselect \HasChildren) "/" "foo1" * LIST (\NoInferiors \UnMarked) "/" "foo1/folder1" * LIST (\Noselect \HasChildren) "/" "iphonemail" * LIST (\NoInferiors \Marked) "/" "iphonemail/foo1" * LIST (\NoInferiors \UnMarked) "/" "Sent" * LIST (\NoInferiors \UnMarked) "/" "Trash" * LIST (\HasNoChildren) "/" "INBOX" * LIST (\HasNoChildren) "/" "sharedimap/cesupport" * LIST (\HasNoChildren) "/" "sharedimap/mimesupport" .

[Dovecot] Adding IMAP SORT and THREAD Extensions but THREAD=ORDEREDSUBJECT functionality to Dovecot 2.x.y !
by Oooo1 30 Jun '12

30 Jun '12

Hi. Can somebody add IMAP SORT and THREAD Extensions THREAD=ORDEREDSUBJECT function to the just next version of Dovecot ? It is necessary to GroupWare server. At the moment I have made it workable together, but there is one unstable point, as I have understood SOGo needs THREAD=ORDEREDSUBJECT sorting functions and if it not to get it, GroupWare server makes unworkable some of its component. If it needs additional info, you are welcome.

[Dovecot] What does "namespace inbox {..." mean
by Jonathan Ryshpan 30 Jun '12

30 Jun '12

I'm trying to set up a dovecot server for which mail arrives in an mbox, and mail is stored in a maildir. The wiki (see http://wiki.dovecot.org/Namespaces) refers to this as "Mixed mbox and Maildir". It advises handling this situation by creating two namespaces: one for the mbox and the other for the maildir. On the other hand the sample configuration coming with dovecot in my distro puts inbox in a namespace starting with: namespace inbox { # Namespace type: private, shared or public #type = private It appears from the wiki that the word following the namespace declarator (if this is the right word) should be either "public", "shared", or "private", and describes a property of the namespace being declared. So what does: namespace inbox {... mean? Similarly in another part of the wiki (see http://wiki2.dovecot.org/Plugins/Virtual) I read that it's possible to have namespace virtual { namespace real { ... which only increases my perplexity. Please advise! Thanks - jon

[Dovecot] Preferred LDAP Attribute for home/mail location
by Edgar Fuß 29 Jun '12

29 Jun '12

Is there, among the dovocot community, any preferred LDAP schema and attribute to use for setting the home/mail storage location? Some people seem to use the qmail schema, some a Jamm schema (whatever that is), and Markus Effinger has even created a dovecot schema (https://www.effinger.org/blog/2009/01/11/eigenes-ldap-schema-erstellen/) There may be more. I could even create my own given we have been assigned an official OID a decade ago anyway. However, sometimes I prefer to use what most other people do. I would effectively only need to store the name of the relevant NFS server.

Hi Kelsey, We're running ZFS here, and have just started using dovecot on it. No stats yet to report, but you might be interested in this edge case. One of our server started behaving badly... the database would randomly crash and not restart due to corrupted indexed. It turns out that the memory had gone bad, and that it had been bad for a while. Disk blocks were getting corrupted on read, and some on write! Luckly because we were on ZFS, which checksums all data, we were able to detect and repair most of the data (some 80mb of bad blocks distributed evenly thoughout the entire file system!) automatically, and also know exactly which files were unrecoverable (in the end just two or three files!). Also, we have hourly snapshots of all the file systems, so we were able to recover older versions of those files with minimal loss. I will never rely on a non-checksumming file system for production use again, for data that is existed to persist over time. Joe

Should I really increase the limit based on my settings? Can these commits fix the reported leak? http://hg.dovecot.org/dovecot-2.0/rev/6299dfb73732 http://hg.dovecot.org/dovecot-2.0/rev/67f1cef07427 Please note that the auth service is restarted when it reach the limit so no real issues, please advice thanks Nicola

[Dovecot] Integrating Dovecot with Amazon Web Services
by Gary Mort 29 Jun '12

29 Jun '12

I did some searching in the mail archives and didn't see any discussion of integration with AWS, so I wanted to through out my thoughts/plans and see if it has been done before. I am setting up my own personal website on EC2 along with an email server, and I really don't like the idea of using the disk drive as permanent mail storage. EBS is too small instance storage is ephermeral. Looking over the docs, the dbox format seems most easily copied for my needs. http://wiki2.dovecot.org/MailboxFormat/dbox To make life easy, I'll stick with just single-dbox as a start, however multi-dbox would be doable. With dbox, the only thing that I need to change is the alternate storage model: "An upshot of the way alternate storage works is that any given storage file (mailboxes/<folder>/dbox-Mails/u.* (sdbox) or storage/m.* (mdbox)) can only appear *either* in the primary storage area *or* the alternate storage area but not both — if the corresponding file appears in both areas then there is an inconsistency." First I want to add AWS S3 as a storage option for alternate storage. Then instead of the above model, the new model would be that email is always stored in alternate storage, and may be in primary storage. So, when mail comes in, I'd have Dovecot save the email to the alternate storage S3 bucket and update the indexs and other information[ideally, for convenience purposes, a few bits of relevant indexing information can be stored as metadata in the S3 object - sufficient so that instead of retrieving the entire S3 object, just the meta data can be pulled to build indexes. When a client attempts to retrieve an email message, Dovecot would check primary storage as it does now, if the message is not found than it will retrieve it from the alternate storage system AND store a copy in the primary storage. Primary storage can be periodically purged, have quota's to keep it from growing too large, etc. In this way, primary storage can be viewed as a message cache, just keeping the messages that are currently of interest, while S3 is the real data. [Ideally, this can be expanded so that when a message comes in, in addition to storing a copy in S3, an AWS SNS notification can be issued so if multiple IMAP servers are running, they can all subscribe to the same SNS channel and update themselves as needed]. This give me unlimited disk storage at S3 prices, I would even like to be able to set a few options based on the folder, so I can enable versioning on important message folders, use the even cheaper reduced redundancy storage for archives, and set expiration dates on email in the trash and spam folders so S3 will automatically purge the messages after a month. Secondly, I'd like to replace the Mysql database usage with a simpleDB database. While simpleDB lacks much of MySQL's sophistication, it doesn't seem that Dovecot is really using any of that, so simpleDB can be functionally equivalent. The primary purpose of using simpleDB is that this way the entire Dovecot system can be ephermeral. When a properly configured dovecot AMI is launched, it will start up, pull it's config data from an S3 bucket, subscribe to the SNS channel for new updates, and then start the Dovecot server. It won't care if it is the only Dovecot server, or if there are 500 other servers running. They all share the same simpleDB database. Whenever any change is made that is relevant to server configuration, a notice is generated to SNS, and all the email is stored in S3. As a starting point, I'm thinking the best place for me to start coding is the single-s3-dbox message store as it has the least moving parts[mainly just fix up the save function to run the way I need it to, and the retrieve function to make a local copy of any incoming email...additional metadata functionality can be added later]. Has anyone else been working on something similar? -Gary

[Dovecot] Mail migration to dovecot with doveadm backup
by Reinhard Vicinus 28 Jun '12

28 Jun '12

Hi, i try to migrate mails from a non dovecot imap server to a dovecot imap server with doveadm backup as described there: http://wiki2.dovecot.org/Migration/Dsync i first tried (local-mailbox port 18143 is the non dovecot imap server): /usr/bin/doveadm -o imapc_user=user(a)example.org -o imapc_password=imappw -o imapc_host=local-mailbox -o imapc_features=rfc822.size -o imapc_port=18143 -o mailbox_list_index=no -v -D backup -R -f -u user(a)example.org -m Sent imapc: and got the following error: dsync(user(a)example.org): Fatal: dsync backup: Looks like you're trying to run backup in wrong direction.

[Dovecot] Default for non-present LDAP attributes?
by Edgar Fuß 28 Jun '12

28 Jun '12

With 1.2, is there a syntax to, for LDAP lookups, use a given fixed replacement for a non-present LDAP attribute? E.g. something that would extend user_attrs = mailFileServer=mail=maildir:/import/mail/%$/%d to use maildir:/import/mail/foo/%d in case the mailFileServer attribute is not present?

[Dovecot] Maildir Seen Flags not heeded when dovecot-shared present
by J E Lyon 28 Jun '12

28 Jun '12

Hi, After many hours of searching (!) and lots of testing procmail scripts, I found the explanation I was looking for -- something you explained at http://www.dovecot.org/list/dovecot/2008-July/032551.html That explains it. Thing is, though, every time I've seen shared mailboxes -- really shared by multiple staff or not -- the preference is in fact for the shared behaviours to also "share" the Seen flags. Typically, someone doesn't want to read an email that someone else has already picked up and started dealing with or responded to. (They'll file it in due course, but the Seen flag is the first indicator that someone's opened and started to deal with it.) Hacking source code and branching and whatnot isn't easy or done lightly, but I wondered if anything else had come to light in recent years about this issue. I'd be as happy getting my procmail script to tell Dovecot to update the index based on the flag, but I'm pretty sure that's not possible :) Any ideas greatly appreciated, thanks. ~ James.

[Dovecot] last hope... public namespace and directory structure
by Daniel Fischer 28 Jun '12

28 Jun '12

hello, I would like to migrate to dovecot, but I have a problem with a public namespace declaration: # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-2-amd64 x86_64 Debian wheezy/sid And here are the relevant parts from the configuration: namespace { location = maildir:/var/mail/vhosts/%d/public prefix = Public. separator = . type = public } namespace inbox { prefix = separator = . subscriptions = yes type = private } I assume that all folders under ./public/ are public mailboxes. The public folder itself is not a maildir, but contains the team mailboxes i.e. ./public/.sales/ ./public/.service/ ./public/.purchase/ The file passwd for those 3 samples looks like this: sales@$DOMAIN::5000:5000::/var/mail/vhosts/$DOMAIN/public/.sales service@$DOMAIN::5000:5000::/var/mail/vhosts/$DOMAIN/public/.service purchase@$DOMAIN::5000:5000::/var/mail/vhosts/$DOMAIN/public/.purchase Note: All other users have mail_location /var/mail/vhosts/%d/%n Now a have the following problem: If I login in as user sales and create a folder foo and in there a folder bar. The directory structure is: ./public/. sales /.foo and /public/. sales /.foo.bar thats exactly what I´m expect. Now I logon as normal user. I can see the namespace Public with the sales mailbox but no subfolder foo or foo.bar. Now I create also the folders foo and in there bar, but the result is to me unexpected ;-): ./public/. sales ./public/. sales.foo ./public/. sales.foo.bar Looking forward to your comment, Daniel

[Dovecot] permissions on auth-userdb

Hi.. im still trying to upgrade to 2.0. Im getting: dovecot: lda: Error: userdb lookup: connect(/var/run/dovecot/auth-userdb) failed: Permission denied (euid=10000(vmail) egid=10000(vmail) missing +r perm: /var/run/dovecot/auth-userdb, euid is not dir owner) the error is correct caus its owned by root. My Questions is who should own it ? Im not sure how that works, what process/user calls the auth-userdb ? The auth-userdb returns the args generated in master.conf, right ? i think comment out the user and group setting in master.conf will fix it but im not sure if that is the securest way. the mails come from postfix via dovecot-lda Hans master.conf service auth { # auth_socket_path points to this userdb socket by default. It's typically # used by dovecot-lda, doveadm, possibly imap process, etc. Its default # permissions make it readable only by root, but you may need to relax these # permissions. Users that have access to this socket are able to get a list # of all usernames and get results of everyone's userdb lookups. unix_listener auth-userdb { mode = 0600 #user = vmail #group = vmail } auth-ldap.conf.ext passdb { driver = ldap args = /etc/dovecot/dovecot-ldap.conf.ext } userdb { driver = static args = uid=vmail gid=vmail home=/home/MAILBOXES/%u/ mail=/home/MAILBOXES/%u/mail }

[Dovecot] The deleted_to_trash Plugin (workaround Outlook 2007 behaviour)
by J E Lyon 27 Jun '12

27 Jun '12

Hi, I see this plugin exists for v1 & v2, all very interesting... Surprised no one seems to have created an RPM and it looks like deleted_to_trash is one of the very few plugins to not be shipped as part of the default install with CentOS 5.5 or CentOS 6 (i.e. Dovecot v1 & v2 respectively.) Am I missing something, or does everyone really build from source? Thanks, James.

[Dovecot] pop3-throttle
by manu＠netbsd.org 27 Jun '12

27 Jun '12

Hello I am having a hard time with users using POP while leaving mailboxes of several gigabyte cumulated. This causes a lot of disk I/O and kills performancs for everyone. I try to encourage people migrating to IMAP, but that migration will take some time, and therefore I am looking for alterantive ways to workaround the problem. I found pop3-throttle-plugin.c, which seems a smart way to solve the problem, unfortunately it comes with no documentation. I was able to build it and load it, bu itsays nothing in the logs. Is there any doc somewhere? Any advices on how to set it up? -- Emmanuel Dreyfus http://hcpnet.free.fr/pubz manu(a)netbsd.org

[Dovecot] Hardware infrastructure for email system
by Michael Wessel 27 Jun '12

27 Jun '12

Hi, I'm currently (re-)planning my email setup and have been doing some research. I have done some searches and read several threads in the areas of my questions here. While there are some that come close I haven't yet been able to get all my questions answered. I currently run a postfix, dovecot & roundcube setup and have about 2000 active accounts. I have a separate SMTP server for outbound mail and auth is done against a separate LDAP server. In front of the POP/IMAP server I have another SMTP (4 in parallel actually) server that receives and filters inbound mail through a company specific, proprietary filter before the mail hits the POP/IMAP server. LDAP & SMTP servers are ESXi VMs. So right now both dovecot and roundcube run on the same box which is a Dell PE2950 with dual quad-core Xeon, 16GB RAM and 6 1TB disks in RAID 6, so only local storage using maildir. So far it's been holding up fine, but it's beginning to show signs of overload now. I also expect an increase in users over the next few months up to somewhere between 10 - 20,000 mail boxes. Hence the re-planning. My first priority in redesigning my setup is reliability. I definitely need something fail-save and as close to always on as possible. Next is performance. And while the budget is of course limited for the moment I'm setting that aside and will worry about that when the time comes. Now here is my question(s): In order to support up to 20,000 mailboxes (distributed over several times-zones so they won't all be used at the same time) with a very reliable service with good performance, what do I actually need? Do I need(ul) SAN or is it just a "would be nice to have"? If yes, why and what would be appropriate for my needs? Or will a setup with a few more servers like the ones I already have, using something like DRBD and distributing services (imap, http, spamd etc) onto different boxes do? I know I have more reading to do on all the different options out there, but would like some input from people that have experience in this area so I can focus on the stuff that's right for my situation.

[Dovecot] doveadm proxy kick in director setups
by Tom Pawlowski 27 Jun '12

27 Jun '12

Something I noticed on a 2.1.7 director test cluster (two directors, three backends): 'doveadm proxy kick user' will kick all connections for that user on that director only. Any additional connections on other directors will remain active unless the command is run on all directors. Are the proxy and director sub-commands intended to be separate and distinct in their operation? If so, then this makes sense, as a proxy isn't necessarily a director. Are there any plans for a proxy kick equivalent that would work across directors? -- Tom Pawlowski OIT-CSS System Administrator office: Hill 145 email: tompru(a)jla.rutgers.edu phone: (732) 445-2634

[Dovecot] director map and mysql
by Костырев Александр Алексеевич 27 Jun '12

27 Jun '12

hello! Is "doveadm director map" command suppose to work when I store "host" value in mysql table? It gives me nothing in output with no errors in log. I've successfully setup directors with static passdb, and decided to give a try setup with storing host value in mysql table. The proxying is actually working, I'm just unhappy with no output from "doveadm director map". on the other hand output from "doveadm director map" is not empty, when I configure my password_query not to return host from table. director's settings in dovecot.sql is: passdb { driver = sql args = /etc/dovecot/dovecot-sql.conf } userdb { driver = sql args = /etc/dovecot/dovecot-sql.conf } director_servers = 192.168.5.125 director_mail_servers = 192.168.5.110 192.168.5.111 service doveadm { inet_listener { port = 24245 } } protocol doveadm { auth_socket_path = director-userdb } doveadm_proxy_port = 24245 in /etc/dovecot/dovecot-sql.conf at director there's password_query = SELECT \ NULL AS password,\ 'Y' as nopassword, \ 'Y' AS proxy, \ MBOX_NAME as user, \ host2 as host \ from M_MAILBOX \ where MBOX_NAME = '%u' user_query = SELECT \ MBOX_NAME AS username, \ MAIL_DIRECTORY as home \ from M_MAILBOX \ where MBOX_NAME = '%u'; iterate_query = select MBOX_NAME AS username from M_MAILBOX; backend's conf: service doveadm { inet_listener { port = 24245 } }

by Martin Schitter 27 Jun '12

27 Jun '12

the configuration keyword "pop3c_master_user" mentioned in the dsync migration documentation (http://wiki2.dovecot.org/Migration/Dsync) does not work for dovecot 2.1.7. a config line like: "pop3c_master_user = cyrus" will produce this error: doveconf: Fatal: Error in configuration file /etc/dovecot/local.conf line 33: Unknown setting: pop3c_master_user it's not defined in: src/lib-storage/index/pop3c/pop3c-settings.* is this feature not enabled with intention? btw. another question: will 'doveadm backup' mirror all the IMAP ACL information? thanks martin

[Dovecot] Dovecot performance under high load (vs. Courier)
by email builder 27 Jun '12

27 Jun '12

Hi, We are building a new system that will support a large number of users (high volume, high concurrent usage, etc). We have played with Dovecot, but in most serious applications we have traditionally used Courier IMAP. It's my (lay) understanding that with indexing and perhaps other things in Dovecot, it might perform better than Courier in larger environments like this. Am I correct or is it less clear-cut? Any tips on making the migration (not migrating an existing system, I mean migrating our paradigm - things to consider, things to watch out for)? TIA

Hi, I'm trying to configure a server to use SAMBA and Winbind to authenticate to Active Directory.... I managed to get this portion up and running even the Dovecot portion. For reference something similar to this guide: http://www.whitneytechnologies.com/?p=119 However PAM is slightly different: # cat /etc/pam.d/dovecot auth sufficient pam_krb5.so no_user_check validate account sufficient pam_permit.so This is what my dovecot.conf file looks like: # cat dovecot.conf # v1.2+: auth_use_winbind = yes auth_winbind_helper_path = /usr/local/bin/ntlm_auth protocols = imap # It's nice to have separate log files for Dovecot. You could do this # by changing syslog configuration also, but this is easier. log_path = /var/log/dovecot.log info_log_path = /var/log/dovecot-info.log # Disable SSL for now. ssl = no disable_plaintext_auth = no # We're using Maildir format #mail_location = maildir:~/Maildir mail_location = mbox:/mail:INBOX=/mail/%u # Authentication configuration: auth_verbose = yes auth_debug = yes auth_username_format = %n auth_mechanisms = plain ntlm login userdb { driver = static # args = uid=501 gid=1001 home=/mail/%u args = home=/mail/%u driver = static } passdb { driver = pam args = failure_show_msg=yes } Now what I would like to know is, which is better for "virtual hosting" Maildir or mbox? Basically my requirement is that I would like to separate users via either individual folders and then put each user's mbox or Maildir in the created directory, or simply name each mbox or Maildir according to the user name. First up is this possible? Secondly, how would I go about doing it? My users are not allowed to login to the system outside of IMAP as it's a Mail only server. Currently I've been looking at many links: http://satish-linuxbug.blogspot.co.uk/2008/08/freebsd-with-active-directory… http://joseph.randomnetworks.com/2005/11/08/freebsd-users-and-groups-with-s… http://wiki2.dovecot.org/HowTo/ActiveDirectoryNtlm http://wiki2.dovecot.org/Authentication/Mechanisms/Winbind http://wiki2.dovecot.org/TestInstallation http://wiki2.dovecot.org/VirtualUsers http://www.linuxmail.info/active-directory-dovecot-pam-authentication/ http://wiki2.dovecot.org/HowTo/SimpleVirtualInstall I'm running dovecot version 2.1.7 on FreeBSD 8.2 x64 RELEASE. The system is not being used as an MTA server meaning that only IMAP transfers are being done using MS Outlook then filtered by Thunderbird. Regards, Kaya

[Dovecot] started with dovecot sieve

As I am new to dovecot and sieve I am really happy to get it working in a straight forward way. Thanks for the documentation to whom it concerns. Now I came to my limits with this failure messages in /home/rolf/.dovecot.sieve.log: sieve: info: started log at Jun 25 20:22:54. error: msgid=<1340648569.94073.YahooMailClassic(a)web190304.mail.sg3.yahoo.com>: failed to store into mailbox 'INBOX': BUG: Unknown internal error. with this messages in mail.info: Jun 25 20:22:54 rolf14 postfix/smtpd[21674]: connect from localhost[127.0.0.1] Jun 25 20:22:54 rolf14 postfix/smtpd[21674]: 90898E0190: client=localhost[127.0.0.1] Jun 25 20:22:54 rolf14 postfix/cleanup[21669]: 90898E0190: message-id=<1340648569.94073.YahooMailClassic(a)web190304.mail.sg3.yahoo.com> Jun 25 20:22:54 rolf14 postfix/qmgr[21172]: 90898E0190: from=<stephanie.otavy(a)live.com>, size=5291, nrcpt=1 (queue active) Jun 25 20:22:54 rolf14 postfix/smtpd[21674]: disconnect from localhost[127.0.0.1] Jun 25 20:22:54 rolf14 dovecot: lda(rolf): Error: setegid(privileged) failed: Operation not permitted Jun 25 20:22:54 rolf14 dovecot: lda(rolf): Error: sieve: msgid=<1340648569.94073.YahooMailClassic(a)web190304.mail.sg3.yahoo.com>: failed to store into mailbox 'INBOX': BUG: Unknown internal error Jun 25 20:22:54 rolf14 dovecot: lda(rolf): Error: sieve: script /home/rolf/.dovecot.sieve failed with unsuccessful implicit keep (user logfile /home/rolf/.dovecot.sieve.log may reveal additional details) I guess the mentioned mail is spam.

[Dovecot] dsync error: "Mailboxes don't have unique GUIDs"

I'm getting an error backing up mailboxes. I'm using the mirror command: dsync -fvo mail_home=/home/users/bob mirror ssh vmail(a)10.1.4.1 dsync -o mail_home=/home/.incoming_mail_migrations/users/bob dsync-remote(vmail): Error: Mailboxes don't have unique GUIDs: 1ef6ee37c694894d783100000581a675 is shared by INBOX and INBOX dsync-remote(vmail): Error: command BOX-LIST failed dsync-local(vmail): Error: Worker server's mailbox iteration failed The mail user doesn't yet exist on the destination yet, thus the use of the mail_home parameter. I found a mailing list message where a person was having a similar problem but I couldn't find confirmation that the issue was resolved. In our case, the backup goes from maildir to mdbox format (we can't to convert to mdbox). Things seemed to be moving along, but there are quite a few examples of dsync failing.

[Dovecot] specifying home/sieve/sieve_dir relative to mail_location
by Edgar Fuß 25 Jun '12

25 Jun '12

With 1.2, is it possible to specify home, sieve and sieve_dir relative to mail_location? I have mail_location = maildir:/import/mail/%n/:INDEX=/var/db/dovecot/indexes/%n and, in the plugin section, home = /import/mail/%n/home sieve = /import/mail/%n/dovecot.sieve sieve_dir = /import/mail/%n/sieve I would like to partially move users to another location (different file server) by using an LDAP entry. I know it's possible to specify everything relative to home, so I could probably use relative ~/../-type paths for mail_locatin etc., but that looks a bit awkward. The VirtualUsers/Home Wiki enty contains an example for relative paths user_attrs = .., mailDirectory=home=/var/vmail/%$ which I do not understand.

[Dovecot] 2.1.7 TLS issues
by Christian Rößner 25 Jun '12

25 Jun '12

Hi, I have an interesting problem: I am building dovecot packages for Ubuntu since 10.04. Never had bigger trouble with it. Now since 2.1.6 or 2.1.7 (I can not say more precisely), Thunderbird 10ESR and Outlook 2010 can no longer use 143/TLS correctly. Automx delvers 143/TLS and Outlook tells me that it can not create a secure connection. I changed automx to use 993/SSL and everything works. Under Thunderbird 10ESR, I get a box that tells me that I need to change settings. When I sent mail, TB told me that it could not copy the mail to the sent folder. I also changed to 993/SSL and everything is perfect. At the other and, Apples Mail.app and iOS devices work perfectly over 143/TLS. So my guess is that it has to do with OpenSSL. Did something change in dovecot concerning TLS? Can I change options in the built process? Thanks in advance -Christian Rößner --- Roessner-Network-Solutions Bachelor of Science Informatik Nahrungsberg 81, 35390 Gießen F: +49 641 5879091, M: +49 176 93118939 USt-IdNr.: DE225643613 http://www.roessner-network-solutions.com

[Dovecot] The deleted_to_trash Plugin (workaround Outlook 2007 behaviour)
by J E Lyon 24 Jun '12

24 Jun '12

Hi, I see the plugin exists for v1 & v2, all very interesting... Surprised no one seems to have created an RPM and it looks like deleted_to_trash is one of the very few plugins to not be shipped as part of the default install with CentOS 5.5 or CentOS 6 (i.e. Dovecot v1 & v2 respectively.) Am I missing something, or does everyone really build from source? Thanks, James.

[Dovecot] Dovecot Quotas in Version 2
by Brian Spraker 24 Jun '12

24 Jun '12

Hello all, Just upgraded from Ubuntu 10.04 to 12.04 on a server today and went through a few issues that I finally got corrected with many different services. However, one of them - I absolutely cannot figure out. I was using Dovecot 1 in Ubuntu 10.04 - but in Ubuntu 12.04, it has been upgraded to Dovecot 2. Finally managed to get the configuration to work and get it to use MySQL as the back-end authentication method (had to install the dovecot-mysql package). But, I cannot get quotas to work. The moment I uncomment a quota line, Dovecot fails to start. Would appreciate any help with this. I am not using any of the individual configuration files on the conf.d folder - simply the dovecot.conf and dovecot-sql.conf file. Here is a copy of those. You can see the one commented line (mail_plugins under imap) simply will not work - but yet the one under POP works (although I don't think it is used): base_dir = /var/run/dovecot/ disable_plaintext_auth = no first_valid_uid = 33 last_valid_uid = 33 listen = * log_timestamp = "%Y-%m-%d %H:%M:%S " mail_privileged_group = www-data passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } plugin { quota = maildir quota_rule = Trash:storage=100M } protocols = imap pop3 service auth { user = root } service imap-login { executable = /usr/lib/dovecot/imap-login } service imap { executable = /usr/lib/dovecot/imap } ssl = no userdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } protocol imap { imap_client_workarounds = mail_plugin_dir = /usr/lib/dovecot/modules/imap # mail_plugins = quota imap_quota } protocol pop3 { mail_plugins = quota pop3_uidl_format = %08Xu%08Xv } And for the dovecot-sql.conf file (passwords changed, of course): driver = mysql connect = dbname=horde user=<USER> password=<PASSWORD> host=localhost default_pass_scheme = PLAIN password_query = SELECT user_uid as user, user_pass as password FROM horde_users WHERE user_uid = '%u'; user_query = SELECT uid, gid, home, maildir, concat('maildir:storage=', quota) AS quota FROM horde_users WHERE user_uid = '%u'; I did not update the dovecot-sql.conf file at all - so I don't know if there maybe be some configuration issue with how it is pulling the quota limit from the database. Quotas are in bytes in the database. Certainly would appreciate any help with this. I went through the Dovecot Quota Configuration in the wiki but it wasn't any help - as I basically already have that line in the config file, but it will fail to start Dovecot. Thank you! Brian S.

[Dovecot] Problems getting auto create plugin to work
by Dr Josef Karthauser 23 Jun '12

23 Jun '12

Hi there, I've configured the 'autocreate' plugin (in v.2.1.6), but it doesn't appear to be working. Can someone help me work out how to work out why please? I've got this in my 20-imap.conf file: protocol imap { mail_plugins = $mail_plugins antispam autocreate } and this in my 90-plugins.conf file: plugin { autocreate = Trash autocreate2 = Spam autosubscribe = Trash autosubscribe2 = Spam ... etc } But, the spam does not get created upon login. I've restart dovecot and restarted my mail client, but there's no hint of an spam folder. Is there something else that I also need to do? Thanks, Joe

[Dovecot] Import from Evolution
by Jonathan Ryshpan 23 Jun '12

23 Jun '12

I need to import the mail database generated by the evolution mail reader into dovecot. Evolution stores its mail in maildir format (fully standards compatible, I think); I would be using the maildir format in dovecot. Is there anything in the wiki, etc. explaining exactly how to do this? Why do this? Evolution is hopelessly broken, and is not likely to be fixed in the forseeable future, and I would like to keep my mails in maildir form. Reviews of kmail are very bad, and thunderbird uses the mbox format for storage. Thanks in advance - jon

[Dovecot] cumulative userdb ?
by Benoit Branciard 22 Jun '12

22 Jun '12

in Dovecot 2.0, is it possible to have kind of "cumulative" multiple userdb ? that is, for all users: - extract some attributes (let's say: uid, gid, home) from a first userdb (Passwd for example), - an extract some other attributes (mail for example, but overwriting those from the first userdb in case of redundancy) from a second userdb (LDAP for example) ? This is *different* from the "multiple databases" setup described in http://wiki2.dovecot.org/Authentication/MultipleDatabases, where it is meant as "failover": the second database is looked up only if the user isn't found in the first database. -- Benoit BRANCIARD Service InfraStructures (SIS) - Direction du Système d'Information (DSI) Université Paris 1 Panthéon-Sorbonne Centre Pierre Mendès France B 406 - 90, rue de Tolbiac - 75634 Paris cedex 13 - France Tél : +33 1 44 07 89 68 - Fax : +33 1 44 07 89 66 Accueil tél. : +33 1 44 07 89 65 Assistance : assistance-dsi(a)univ-paris1.fr Web : http://dsi.univ-paris1.fr -- Ce message a ete verifie par MailScanner pour des virus ou des polluriels et rien de suspect n'a ete trouve.

[Dovecot] Dovecot LDA, Offlineimap and Sieve
by Johnny 22 Jun '12

22 Jun '12

Hi, I am trying to st up Offlineimap to use Dovecots LDA to be able to use Sieve for mail filtering, but am not sure how to get this working. I think the right way would be to use 'preauthtunnel' in .offlineimaprc and try the setup below, which doesn't work. ,----.offlineimaprc | [Repository LocalRepository] | type = IMAP | preauthtunnel = ssh -q localhost '/usr/libexec/dovecot/deliver -d myloginid' `---- If I go via the network card, the snch is fine, but Sieve can't be used? ,---- | [Repository LocalRepository] | type = IMAP | preauthtunnel = MAIL=maildir:$HOME/Maildir/myMailDir /usr/libexec/dovecot/deliver -d mylogonid | remotehost = localhost | port = 143 | remoteuser = mylogonid | remotepass = mypassword `---- Has anyone got any tips on how to get offlineimap to send mail to Dovecot in a way that Siev3e can be used? thanks! -- Johnny

[Dovecot] LDA vs maildrop... LDA *and* maildrop?
by email builder 22 Jun '12

22 Jun '12

We're considering a move from Courier to Dovecot. So far, looks like it's not too bad, but the most challenging obstacle is what to do about our local delivery. Factors: 1. we use a lot of maildrop "features" that are impossible in sieve without piping to an external program (would rather not re-write our working maildrop scripts in another language) 2. would love to try dbox 3. we use IMAP/Maildir++ quotas (looks like with a little finesse it's possible to get maildrop and dovecot to play nice on this account, yes?) I saw it suggested to just call LDA from maildrop for any maildrop "to" commands (hmmm, what about "cc"?) here: http://article.gmane.org/gmane.mail.imap.dovecot/56120 How much overhead will this take? Would it be possible or advisable to use LMTP instead if that would help? Is this idea just too crazy?

[Dovecot] Manual manipulation of Sieve files
by email builder 22 Jun '12

22 Jun '12

We have some scripts that take care of some tasks when creating new email accounts, such as creating some default mail filter rules. I know Sieve scripts are plain text files, but need to be compiled for use. I see that you can use seivec to compile scripts manually, which can help me create .dovecot.svbin which can be placed where needed and permissioned correctly. But a couple questions: * Sieve has the concept of an active script - is this merely whatever is compiled into the .dovecot.svbin file? * Does dovecot (managesieve) do any other housekeeping when a user sieve script is installed and set as the active script? I would need to replicate this manually. * If the default script is always the same (sorry, for us, the solution isn't global scripts), would it work to compile that script once, keep the compiled version somewhere and merely copy it into the correct place for a new user? Are there issues with this? * Should we always have the plain text version along with the compiled one for proper managesieve operation going forward (users can edit their sieve scripts) Thank you

[Dovecot] Dovecot proxy/director and mail pop3/imap backend service on same server
by Aerion Stevens 22 Jun '12

22 Jun '12

Hi all, I am interested in running a Dovecot Proxy(with Director) on the same server as the main Dovecot IMAP/POP3 service. I have a basic Proxy/Director configuration working, however I am struggling with getting the Proxy and IMAP/POP3 service to coexist on the same server. I plan to use three IMAP/POP3 servers with a NFS/maildir backend, and I am playing with Dovecot 2.1.5 at the moment. I have two seperate configurations, one for the Proxy/Director and one for the Dovecot IMAP/POP3 "mail backend servers". For this to work my thoughts are that I will need to run the Proxy/Director imap/pop3 login process on the standard ports 143, 110, 993, 995 and for the Dovecot IMAP/POP3 mail backend service running on the same server will need to use different ports (I decided to be 9143, 9110, 9993, 9995 for example). How do I tell the director to proxy incoming imap/pop3 connection to the mail backend servers running on ports 9143, 9110, 9993, 9995 rather than the default imap/pop3 ports? Using the default ports will clearly cause loops. Can anyone kindly provide an example snippet of config that tells the director to use different port for IMAP and POP3 proxy? I have so far found the following pages helpful to what I am working on: http://wiki2.dovecot.org/PasswordDatabase/ExtraFields/Proxy http://wiki2.dovecot.org/PasswordDatabase/ExtraFields http://wiki2.dovecot.org/Director Cheers, Aerion.

[Dovecot] GlusterFS + Dovecot

Hello, Has anyone used GlusterFS as storage file system for dovecot or any other email system..? It says that it can be presented as a NFS, CIFS and as GlusterFS using the native client, technically using the client would allow the machine to read and write to it, therefore, I think that Dovecot would not care about it. Correct? Anyone out there used this setup?? Thanks.
