[Dovecot] 2.0.12 Coredump under Solaris 10

hi, I've installed a testversion from 2.0.12 and getting coredumps after login via IMAP/POP3.

[Dovecot] calling dovecot exported auth from Java
by WJCarpenter 30 Apr '11

30 Apr '11

As far as I have been able to figure out, dovecot auth always works over a Unix domain socket. I believe it is not currently possible to operate dovecot auth over an Internet domain (TCP) socket. Am I correct? I want to call dovecot's exported authentication from a Java application. Java doesn't natively know how to talk to a Unix domain socket, so there are inconveniences. There are 3rd party JNI libraries to allow Java to do it, but I'm not too wild about the idea of using JNI. My current thinking is to rig up some kind of proxy/shuttle arrangement between a localhost TCP port and the dovecot auth Unix domain socket in the filesystem. I'm looking at using the more or less standard tool "socat" to do that. ('m on a mainstream Linux distribution.) Has anyone else confronted and solved this problem? Do tell us the details .... :-) TIA!

[Dovecot] linking problems of dovecot 2.0.3
by Funda Wang 30 Apr '11

30 Apr '11

Hello, I'm currently packaging dovecot 2.0.3 under Mandriva Linux. It has been using LDFLAGS="-Wl,--as-needed -Wl,--no-undefined" for shared libraries for over two years[1]. And I've found there are lots of linking problems with dovecot 2.0.3. After some investigation, I've made small patch regarding dovecot 2.0.3, posted here: http://svn.mandriva.com/cgi-bin/viewvc.cgi/packages/cooker/dovecot/branches… Even after applying mentioned patch, it still produce following errors: make[3]: Entering directory `/tmp/dovecot/BUILD/dovecot-2.0.3/src/login-common' /bin/sh ../../libtool --tag=CC --mode=link gcc -std=gnu99 -O2 -g -pipe -Wformat -Werror=format-security -Wp,-D_FORTIFY_SOURCE=2 -fstack-protector --param=ssp-buffer-size=4 -fstack-protector-all -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -Wstrict-aliasing=2 -export-dynamic -Wl,--as-needed -Wl,--no-undefined -Wl,-z,relro -Wl,-O1 -Wl,--build-id -o libdovecot-login.la -rpath /usr/lib64/dovecot liblogin.la ../lib-dict/libdict.la ../lib-dovecot/libdovecot.la -lrt libtool: link: gcc -shared -Wl,--as-needed -Wl,--whole-archive ./.libs/liblogin.a ../lib-dict/.libs/libdict.a -Wl,--no-whole-archive -Wl,--as-needed -Wl,--no-undefined -Wl,-z -Wl,relro -Wl,-O1 -Wl,--build-id -Wl,-rpath -Wl,/tmp/dovecot/BUILD/dovecot-2.0.3/src/lib-dovecot/.libs -Wl,-rpath -Wl,/usr/lib64/dovecot -L/usr/lib64/ -lssl -lcrypto -ldl -lpthread ../lib-dovecot/.libs/libdovecot.so -lrt -Wl,-soname -Wl,libdovecot-login.so.0 -o .libs/libdovecot-login.so.0.0.0 ./.libs/liblogin.a(client-common.o): In function `get_var_expand_table': /tmp/dovecot/BUILD/dovecot-2.0.3/src/login-common/client-common.c:372: undefined reference to `login_binary' ./.libs/liblogin.a(client-common.o): In function `client_create': /tmp/dovecot/BUILD/dovecot-2.0.3/src/login-common/client-common.c:50: undefined reference to `client_vfuncs' ./.libs/liblogin.a(client-common-auth.o): In function `client_auth_parse_args': /tmp/dovecot/BUILD/dovecot-2.0.3/src/login-common/client-common-auth.c:111: undefined reference to `login_binary' /tmp/dovecot/BUILD/dovecot-2.0.3/src/login-common/client-common-auth.c:99: undefined reference to `login_binary' ./.libs/liblogin.a(client-common-auth.o): In function `client_auth_begin': /tmp/dovecot/BUILD/dovecot-2.0.3/src/login-common/client-common-auth.c:491: undefined reference to `login_binary' ./.libs/liblogin.a(login-settings.o): In function `login_settings_read': /tmp/dovecot/BUILD/dovecot-2.0.3/src/login-common/login-settings.c:195: undefined reference to `login_binary' ./.libs/liblogin.a(main.o): In function `login_access_lookup_next': /tmp/dovecot/BUILD/dovecot-2.0.3/src/login-common/main.c:185: undefined reference to `login_binary' ./.libs/liblogin.a(main.o):/tmp/dovecot/BUILD/dovecot-2.0.3/src/login-common/main.c:338: more undefined references to `login_binary' follow ./.libs/liblogin.a(main.o): In function `main': /tmp/dovecot/BUILD/dovecot-2.0.3/src/login-common/main.c:358: undefined reference to `login_process_preinit' ./.libs/liblogin.a(main.o): In function `main_init': /tmp/dovecot/BUILD/dovecot-2.0.3/src/login-common/main.c:308: undefined reference to `clients_init' ./.libs/liblogin.a(main.o): In function `main_deinit': /tmp/dovecot/BUILD/dovecot-2.0.3/src/login-common/main.c:317: undefined reference to `clients_deinit' ./.libs/liblogin.a(sasl-server.o): In function `anvil_check_too_many_connections': /tmp/dovecot/BUILD/dovecot-2.0.3/src/login-common/sasl-server.c:187: undefined reference to `login_binary' collect2: ld returned 1 exit status Could somebody take a look?

[Dovecot] Help a newbie...
by Juan Bernhard 29 Apr '11

29 Apr '11

Hi every one! Im new to the list, and to dovecot. I foud this program very usefull, scalable and with a serious security focus. So Im trying to implement it here at work. The first logical step is to read as much as I can, to build the best possible configuration avaible... but i found that the wiki es a pour source of serious information, filled with examples... examples are great to learn, but I was loocking for something that describes every dovecot.conf option (for example: mail_location = *string* default: mbox:~/mail:INBOX=/var/mail/%u bla,bla,bla...) Or perhaps some one can give me some directions to start reading... any help will be great. Thank you!

[Dovecot] Dovecot Folder Creation Problem
by Ceyhun Ganioglu 29 Apr '11

29 Apr '11

Hi all, I installed Dovecot-Postfix as an IMAP mail server and also RoundCube as webmail. When I create an account using Postfix Admin and login to webmail, roundCube creates the Junk Mail, Deleted Emails folder automatically. I also added this account to my Microsoft Outlook 2007. Following some tutorials on the internet I created an Outlook rule to move the sent emails to the IMAP server's sent mail folder. When I send an email, the email disappears from the default sent items of Outlook but it doesn't appear on the IMAP server's sent items folder. Do I have to set some kind of other permissions on the IMAP server to fix this problem? My version of Dovecot is 1.2.16. I want my clients use Microsoft Outlook and reach all received and sent emails via webmail anywhere they go. Many thanks Ceyhun

[Dovecot] Problem Authenticating with Master User
by Henry Franco 29 Apr '11

29 Apr '11

Dovecot provides a master login (a master user name and password that can log into all user accounts). I've setup Dovecot as per: http://wiki1.dovecot.org/Authentication/MasterUsers Here's my problem. The only way I can authenticate successfully is if I try to authenticate through telnet twice. Also, imapsync (the tool I need to use to migrate over emails from Dovecot to other mail server) won't work because of this. $ telnet mail01.server.com 143 Trying 10.10.10.12... Connected to mail01.server.com. Escape character is '^]'. * OK Dovecot ready. 1 login user(a)server.com*master my_password 1 NO Authentication failed. 1 login user(a)server.com*master my_password 1 OK Logged in.

[Dovecot] Re-downloading mails after migrate server
by Esther Yébenes --Conzentra-- 29 Apr '11

29 Apr '11

Hi all, first of all, I must say that I am pretty new to mailing lists, so please, if I do something wrong, just tell me. Now, my problem. I'm migrating a mail service from a temporal to a definitive server. Both servers have the same versions (Postfix, Dovecot -1.0.7, POP3 & IMAP services-, MySQL) and it all works perfectly. The only problem is with the users that store their mail on the server; on the testing, when I check if there is new mail, I download the mail stored on the new server once more. After that, it works correctly (no more unwanted downloads), but I need to avoid that first download. I have been investigating before writing to the list. I have checked that UIDL are the same on both servers, and the configuration is exactly the same except for the name of the server; I have seen in few places that it may be the cause for downloading thdovecote mail again, so I changed the name of the new server to the old's one, but it happened again. I know that lots of servers are migrated every day, and never heard about those problems, so I suppose it must be a solution for this, or maybe a better way to configure the servers. If you wanna take a look at the configuration of both servers, I have pasted them on here --> http://pastebin.ca/2051228 Please, let me now if you need any more information.

[Dovecot] [dovecot] Question about master user and PAM with dovecot 2.0.12

Is it possible to allow master users to be authenticated against PAM? Something like: passdb { driver = pam #args = /etc/dovecot/passwd.masterusers master = yes #pass = yes } and then have a userdb which qualifies what accounts are master accounts but doesn't have passwords? Thanks, Jonathan

Re: [Dovecot] Dovecot Folder Creation Problem

Hi Robert, Many thanks for your reply. I realized that the title of my email was not explaining my exact problem. My problem is not the creation of the folders. I am happy with the folders created by RoundCube. I am confused why Outlook can't write to the Sent Items folder. Logically Outlook, TB or any other email client must have permission to write the sent mails to the chosen sent mail folder on an IMAP server without any problems. Am I wrong?

[Dovecot] how to limit size of dovecot.log
by Aaron C Johnson 29 Apr '11

29 Apr '11

I've done some searching and maybe I'm missing something... I have a remote dovecot and postfix server running on debian 5. I then have a local fetchmail server that retrieves email from the dovecot server via pop3s every 5 minutes. The problem is that the /var/log/dovecot.log file has grown to be over 1.1GiB over a period of less than 1 year. Is there a way to limit the size of the dovecot.log file, or do I have to run a monthly cron job or something to take care of it for me? Thank you, Aaron Johnson

[Dovecot] dovecot lda aliases doesn't work
by Selcuk MIYNAT 28 Apr '11

28 Apr '11

Hi, I am trying to use dovecot as lda. I have put this line in my .qmail-default file: #|/var/qmail/bin/preline -f /usr/local/libexec/dovecot/dovecot-lda -d $EXT@$USER It is working correct with real addresses but couldn't find forwarding addresses. This is my /usr/local/etc/dovecot-sql.conf: driver = mysql connect = host=localhost user=vpopmailuser password=vpopmailpassword dbname=vpopmail default_pass_scheme = PLAIN password_query = SELECT CONCAT(pw_name, '@', pw_domain) AS user, pw_clear_passwd AS password FROM vpopmail WHERE pw_name = '%n' AND pw_domain = '%d' user_query = SELECT pw_dir as home, 89 AS uid, 89 AS gid FROM vpopmail WHERE pw_name = '%n' AND pw_domain = '%d' It is querying vpopmail table all the time but forwarding addresses are in the valias table, so it couldn't find forwarding addresses.

[Dovecot] What is the recommended way to move a message from one mailbox to another using CLI
by Uffe Jakobsen 27 Apr '11

27 Apr '11

What is the recommended way to move a message from one mailbox to another using CLI - serverside commands ? Since IMAP does not support transactional moves between mailboxes - The only thing that comes to my mind is this operation: 1) extract message from mailbox A using "doveadm fetch" 2) inject message into mailbox B using "dovecot-lda" 3) expunge message from mailbox A using "doveadm expunge" it this the right solution ? One problem with above approach is that injecting through "dovecot-lda" will trigger the sieve script - which I'm not interested in since the message have already been injected and processed once before - at delivery... Any advice is much welcome -- View this message in context: http://old.nabble.com/What-is-the-recommended-way-to-move-a-message-from-on… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] What is the recommended way to delete a message from a mailbox ?
by Uffe Jakobsen 27 Apr '11

27 Apr '11

Hi, I'm implementing a shell-script (pseudo) solution to the missing IMAP Outbox feature in Dovecot (Courier IMAP feature http://www.inter7.com/courierimap/INSTALL.html#imapsend) In order to remove the message from the Outbox once it is sent I have a question: What is the recommended way to delete a message from a mailbox (from an "external" server side program - such as a shell script) ? Can I just remove the file from the mailbox - I cannot seem to find any doveadm commands that does this task. I guess that Dovecot over time will discover that the atime and mtime of its indexes and maps does not reflect reality - or is there another (better) way to delete a message. Thanks Uffe -- View this message in context: http://old.nabble.com/What-is-the-recommended-way-to-delete-a-message-from-… Sent from the Dovecot mailing list archive at Nabble.com.

Robert Schetterer <robert(a)schetterer.org> writes: >> Anyway, why use lmtp over lda ? > > i.e avoid backscatter by overquota A clarification on this: backscatter (or rather, ambiguous NDR notices that claim many users are over quota rather than just one) is a result of a local mailer that support multiple recipient delivery in one invocation, but can only return one result code to the MTA. Since Dovecot's deliver-lda does not support multiple recipient delivery, this is not a problem. LMTP can support multiple deliveries of the same message per invocation, but replies with individual SMTP codes to avoid the above problem. It can take advantage of this to efficiently implement single instance storage if it is enabled. > performance should better too Apart from multiple deliveries or SIS, I'm not sure this is true, or significant if it were.

Multiple mirrors (seems like you have plenty of offers) preferrably is multi geographical regions, using DNS round robin with TTL 0 on www and ftp , I wouldnt bother with the wiki mirroring though.

If this is an SMTP relay server, I'm surprised you bothered to install an IMAP server at all. It would have been easier to simply alias postmaster@ to another account on another machine where you do store mailboxes. I.e. simply 'forward' all postmaster mail to you main account and use Sieve to sort all postmaster mail into a folder. This is exactly what I do. It's what a lot of people do, especially those handling many domains, and thus having lots of postmaster addresses. > A question about where the mail is actually supposed to be delivered to... > initially I configured Exim4 to delivery the email to ~/Maildir and I > noticed as you saw in the list directories like ~/Maildir/new and > ~/Maildir/cur, however once I configured Evolution to login to Dovecot I > noticed the directories ~/Maildir/INBOX/new and ~Maildir/INBOX/cur were > created. Should therefore Exim4 be configured to ~/Maildir/INBOX instead of > just ~/Maildir ? Configuration of maildir can be a little confusing the first time around. Given your situation/server, I'm really surprised you didn't use mbox instead. It fits this scenario much better than maildir. > Voila!

Setting up Dovecot LDA with EXIM: http://wiki1.dovecot.org/LDA/Exim You're probably using procmail or maildrop currently. I don't use either of these, so I'm unfamiliar with their setup WRT maildir. Should be pretty straightforward though. > RoundCube still isn't working but I'm not going to worry about that - > Evolution will be cool. Need more details to help with RC. As long as you can establish an IMAP connection to Dovecot, RC is pretty smart about figuring out where everything is even if you don't explicitly tell it. > Thanks for your help - simply confirming one setting helps. Heh, I didn't do much, but you're welcome. Are you planning on migrating all the mailboxes from the old server to this new one? -- Stan

[Dovecot] Having trouble getting Dovecot to read a ~/Maildir configuration
by Murray Collingwood 26 Apr '11

26 Apr '11

Hi folks Setting up a new server, hence a few software packages have been upgraded / changed. On my old server (only 2 years old) I was using Dovecot and RoundCube (web mail app) and had a good experience so was keen to use these again. The only major change is I have switched from sendmail to exim4 (which was installed by default on this Debian server). Exim4 appears to be doing the right thing, however read on and see if you can spot the error. I've tried two email clients, RoundCube (via apache) as a local connection and Evolution as a remote connection. Both appear to login to the Dovecot IMAP connection okay (log entries included further down), although they don't see any email. The INBOX is completely empty. Although when I check out /home/postmaster/Maildir/new it has many messages waiting to be read. It's like Exim4 is delivering the email into the ~/Maildir folder but Dovecot is not seeing it.... I've tried these three combinations in dovecot.conf but they give the same result: #mail_location = maildir:~/Maildir (ie this one I commented the line out to see if Dovecot would work it out automatically) mail_location = maildir:~/Maildir (I think this one should work) mail_location = maildir:~/Maildir:LAYOUT=fs (Now I'm just desperate and will try anything) The dovecot log gives no indication of any errors: This is the version I am running - it was the default version for Debian installed via apt-get: 2011-04-21 08:55:22 dovecot: Info: Dovecot v1.2.15 starting up (core dumps disabled) This connection is using Evolution email client on Linux: 2011-04-21 08:40:05 imap-login: Info: Login: user=<postmaster>, method=PLAIN, rip=122.148.149.28, lip=202.125.41.111 This connection is using roundcube via apache on the same server: 2011-04-21 08:40:41 imap-login: Info: Login: user=<postmaster>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured 2011-04-21 08:40:41 IMAP(postmaster): Info: Disconnected: Logged out bytes=39/443 And finally a look at the ~/Maildir content for my "postmaster" user: root@ds5683:/etc/dovecot# ls -al /home/postmaster/Maildir total 148 drwx------ 6 postmaster postmaster 4096 Apr 21 08:55 . drwxr-xr-x 3 postmaster postmaster 4096 Apr 19 08:12 .. drwx------ 2 postmaster postmaster 12288 Apr 21 08:40 cur -rw------- 1 postmaster postmaster 89088 Apr 21 08:40 dovecot.index.cache -rw------- 1 postmaster postmaster 2376 Apr 21 08:40 dovecot.index.log -rw------- 1 postmaster postmaster 5208 Apr 21 08:40 dovecot-uidlist -rw------- 1 postmaster postmaster 8 Apr 21 08:55 dovecot-uidvalidity -rw------- 1 postmaster postmaster 0 Apr 21 08:34 dovecot-uidvalidity.4daf5f73 drwx------ 5 postmaster postmaster 4096 Apr 21 08:56 INBOX drwx------ 2 postmaster postmaster 12288 Apr 21 09:39 new drwx------ 2 postmaster postmaster 4096 Apr 21 09:39 tmp So, can somebody help me get Dovecot to recognise the messages in this mailbox please? You can suggest anything you like.... upgrades, conf changes, low level formating of HDD... at this stage I'm ready to try anything!

Hi all I hope to get some help on the separator. I am sure that I hava a wrong understanding what the separator is. I thaught the separator is the delimiter within the imap folder structure. For example: Imap folder structure: folder Flights, subfolder Lufthansa If the delimiter is . the ls a command should result: .Flights .Flights.Lufthansa If delimiter is / Flights Flights/Lufthansa I tried several delimiters but only the . Works.

[Dovecot] sieve & plus addressing
by Jerry 22 Apr '11

22 Apr '11

Assume and e-mail address of: me+dovecot(a)domain.com I have a sieve script that sorts mail into the appropriate folders using "+" addressing. I want to extend it to also work with mailing list like this one. A post from the dovecot forum arrives with a Delivered-To: me+dovecot(a)domain.com when I receive it. The "To" is to dovecot. I cannot figure out a way to get sieve to filter on the "Delivered-To" portion rather than the "To" portion using plus addressing. There are several other names; i.e, john, joe, bill, nancy, etcetera that would have the plus suffix of (in this scenario anyway) dovecot. Filtering on each individual address would be a real PIA. I believe it is not supported though. EXAMPLE: This works fine when filtering on the "To" attribute: Assuming email address: me+dovecot(a)domain.com ## Plus Addressing if envelope :detail "To" "dovecot" {fileinto "Dovecot"; stop;} Unfortunately, I cannot substitute the "Delivered-To" attribute in place of the "To" one. I know and currently do sort based on the "List-ID" attribute; however, I have other reasons for wanting to sort only on the delivery address. Is there anyway to actually incorporate the plus addressing feature with the delivery address? -- Jerry ✌ Dovecot.user(a)seibercom.net Disclaimer: off-list followups get on-list replies or get ignored.

[Dovecot] the right way to delete mailbox/user home

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Dear list, we are using dovecot with mdbox to provide mail services for a community of 1000 academic users. We have quite a big turnover of guest users, so we often have to deprovision the allocated resources, that is the mailboxes. Given that the users are virtual, and that the mdbox directory is located in the home directory of each virtual user (static userdb), is it ok to simply delete (rm -rf) the home directory to get rid of the mailbox? Could the delete, without say a dovecot reload, be harmful for dovecot processes and the like? thanks davide - -- Dott.

[Dovecot] Running mailfront under dovecot2.x service supervision
by Uffe Jakobsen 21 Apr '11

21 Apr '11

Hello, Hello, I'm trying to run mailfront SMTP (http://untroubled.org/mailfront/) under Dovecot 2.x process/service supervision My intention was to utilize the fact that dovecot2.x seems to have some kind of generic process/service supervision as well as builtin ssl support. But I cannot get the most simple generic service setup (without ssl) to work. Currently running dovecot 2.0.11 on FreeBSD 8.1 service smtp-auth { executable = /usr/local/bin/smtpfront-qmail inet_listener smtp-auth { port = 587 ssl = no } } I have added the above to dovecot.conf Once I start dovecot everything seems fine - no errors in the log But at the first attempt to telnet to localhost port 587 - I instantly get the indication of never ending forks in the dovecot log (see below) - neither do I get the SMTP prompt that I expected in my telnet session - it just hangs. Apr 19 10:05:34 smtp-auth: Error: mailfront[43539]: bytes in: 0 bytes out: 29 Apr 19 10:05:34 smtp-auth: Error: mailfront[43541]: bytes in: 0 bytes out: 29 Apr 19 10:05:34 smtp-auth: Error: mailfront[43543]: bytes in: 0 bytes out: 29 Apr 19 10:05:34 smtp-auth: Error: mailfront[43545]: bytes in: 0 bytes out: 29 Question is if I've misconfigured something or if it is impossible to utilize dovecot2.x this way ? PS: Now I know that I could use daemontools or such for this task - but I like the dovecot ssl handling and would like to end up by wrapping this smtp service inside same dovecot ssl that I use for IMAPS. Any feedback is more than welcome - I'm stuck Thanks in advance Uffe -- View this message in context: http://old.nabble.com/Running-mailfront-under-dovecot2.x-service-supervisio… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] Umask of Homedir
by Francisco Wagner C. Freire 20 Apr '11

20 Apr '11

Hello, I following the instrucions of: http://wiki2.dovecot.org/SharedMailboxes/Permissions When the user receive the first mail, dovecot create the directory structure always using mode 0700, if i change the permission of the user maildir all new mails arrived get the correct umask: dovecot: lmtp(24960, *): Debug: Namespace INBOX.: Using permissions from .../maildir: mode=0770 The problem is: I need to all accounts have the permission 0770. Tried to use the option: mail_access_groups but doesn't work at all when the first creation of the user path. "For example a simple way to set up shared mailbox access for all system users is to make all mail dirs/files 0770/0660 mode and owned by group "sharedmail" and then set mail_access_groups=sharedmail. Using more fine grained groups of course leaks less mail data in case there's a security hole in Dovecot" Is a bug?

[Dovecot] help with MYSQL and dovecot

20 Apr '11

Hello all: I understand I can't provide to much information; at the moment, I do not have dovecot installed. Here is the problem. I started out running saslauthd, but there appears to be a problem where memory isn't freed after someone fails to authenticate, which leads to a huge dos attack. I hit this problem a couple of times, and it looks like some poor lonely soul (or bot, as it may be) with no life decided to go after my server again today. I had previously tried to configure dovecot, but I have an odd mysql setup, so it was particularly dificult. I am leaving out of town tomorrow afternoon and will not have internet, so I want to make sure this is going to be running as it should be. Here is the info from the dovecot configuration file for mysql. It was giving an error about "username" when I tried to run this. If someone can't spot the problem from this, I will disable courier and reinstall dovecot tonight so I can get the exact error. userdb static { args = uid=vmail gid=vmail home=/home/vmail/%d/%n password_query = select email as user, password,\ home AS userdb_home, uid AS userdb_uid, gid AS userdb_gid \ from users where email = '%u' user_query = \ SELECT home AS userdb_home, uid AS userdb_uid, gid AS userdb_gid \ FROM users WHERE email = '%n'; } And here is the describe for both tables: mysql> describe users; +----------+-------------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +----------+-------------+------+-----+---------+-------+ | email | varchar(80) | NO | PRI | NULL | | | password | varchar(20) | NO | | NULL | | +----------+-------------+------+-----+---------+-------+ 2 rows in set (0.00 sec) -- mysql> describe domains; +--------+-------------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +--------+-------------+------+-----+---------+-------+ | domain | varchar(50) | NO | PRI | NULL | | +--------+-------------+------+-----+---------+-------+ 1 row in set (0.01 sec) Thanks, Ty

[Dovecot] Debug new emails?
by Beto Moreno 20 Apr '11

20 Apr '11

Hi guys. I would like to debug all the new emails arrive to the users mailbox, I have some issue with 1 users that claim that is losing some important emails. The issue that I are not logging to much info in dovecot, I had read the mail_log plugin wiki is not difficult to setup. I want to see went the users receive the new emails, because postfix have the log that say" "sent" from the envelop to the issue user, but I the user say that he didn't receive the email, check his emails and is true I didn't see those 2 emails that postfix send to the user mailbox. I check my spam server and is not blocking that envelop, the spam is not causing this. I'm using Centos 5.4 Postfix 2.3.x Dovecot 1.0.x,but reading mail_log plugin say that we need 1.2.x, can I still use this plugin or I have other options? Thanks!!!

[Dovecot] expire-tool skipping mailbox
by Alex Reinhart 20 Apr '11

20 Apr '11

Hello, I have dovecot set up with expire-tool to nuke Junk messages greater than 30 days old. On a server with many user accounts, it seems to work on most of them. However, on my user account, expire-tool skips my Junk folder entirely, despite it containing messages from January of this year. Here is the expire-tool --test output: Info: alex(a)scienceforums.net/Junk: timestamp 1284027481 (Thu Sep 9 05:18:01 2010) -> 1304023056 (Thu Apr 28 15:37:36 2011) Then it skips to the next mailbox. (Note that I intentionally set the timestamp back to force it to consider my mailbox.) I don't understand why it doesn't want to expunge my 2700 junk messages when it will expunge several thousand in other accounts happily. The expire plugin has been enabled for probably over a year, so all of the messages should be tracked. My only hypothesis is that it has something to do with variables in the mail_location; however, mail_location should be overridden by a user_query, though that contains variables too. Would this account for the issue? It seems unlikely, since other users on the server work just fine. dovecot -n output for the interested: # 1.2.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-24-server x86_64 Ubuntu 10.04.2 LTS ext3 base_dir: /var/run/dovecot/ log_timestamp: %Y-%m-%d %H:%M:%S protocols: managesieve imaps pop3s listen(default): *:143 listen(imap): *:143 listen(pop3): *:110 listen(managesieve): * ssl_listen(default): *:993 ssl_listen(imap): *:993 ssl_listen(pop3): *:995 ssl_listen(managesieve): login_dir: /var/run/dovecot//login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login login_executable(managesieve): /usr/lib/dovecot/managesieve-login first_valid_uid: 150 last_valid_uid: 150 mail_privileged_group: mail mail_location: maildir:/var/vmail/%d/%u mbox_write_locks: fcntl dotlock mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_executable(managesieve): /usr/lib/dovecot/managesieve mail_plugins(default): quota imap_quota expire mail_plugins(imap): quota imap_quota expire mail_plugins(pop3): quota expire mail_plugins(managesieve): mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 mail_plugin_dir(managesieve): /usr/lib/dovecot/modules/managesieve lda: mail_plugins: quota sieve expire postmaster_address: postmaster(a)xyloid.org sendmail_path: /usr/lib/sendmail auth_socket_path: /var/run/dovecot/auth-master sieve_global_path: /etc/dovecot/sieve.global auth default: user: nobody passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: sql args: /etc/dovecot/dovecot-sql.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 432 user: vmail group: mail plugin: quota: dict:user::proxy::quotadict quota_rule: *:storage=1G quota_rule2: Trash:storage=10%% quota_rule3: Junk:ignore sieve: /var/vmail/%d/%n/dovecot.sieve expire: Trash 7 Trash/* 7 Junk 30 expire_dict: proxy::expire dict: quotadict: mysql:/etc/dovecot/dovecot-dict-quota.conf expire: mysql:/etc/dovecot/dovecot-dict-expire.conf And dovecot-dict-expire.conf: connect = host=localhost dbname=mail user=mail password=[password] map { pattern = shared/expire/$user/$mailbox table = expires value_field = expire_stamp fields { username = $user mailbox = $mailbox } } Thanks. - Alex Reinhart

Hello, I'm using pigeonhole-0.2.3, it works fine. I tried to verify some build in checks of vacation concerning precedence or auto-submitted header lines. It looks like sieve-test ignores header lines like Auto-Submitted: auto-submitted Precedence: bulk Return-Path: MAILER-DAEMON@... if I have a vacation script like require ["vacation", "regex", "fileinto", "variables", "envelope"]; if allof (header :regex ["to"] ["address1", "address2"], header :matches "to" "*") { vacation :days 7 : ... "text"; } The email to test contains a line like Precedence: bulk or Return-Path: <MAILER-DAEMON@...> or Auto-Submitted: yes sieve-test -D -C script.sieve mail I get Performed actions: * send vacation message: => seconds : 604800 ... text of vacation message END MESSAGE Implicit keep: * store message in folder: INBOX sieve-test(root): Info: final result: success -- Regards --- Burckhard Schmidt

[Dovecot] Question about Outlook workarounds
by Michael Durket 19 Apr '11

19 Apr '11

Do the Outlook workarounds in Dovecot 1.x still apply to current versions of Outlook? Or has Microsoft fixed Outlook such that workarounds are no longer needed in Dovecot (and if so, after what version of Outlook can I remove the workaround settings in my dovecot.conf file)?

I've got things working now so that I can build applications with the openssl built by Sun to tap into the cryptographic accelerators on the T2. It turns out that the /opt/coolstack stuff related to openssl is actually symlinks to /usr/sfw. So, in the Makefile, if I set the openssl directory to /usr/sfw, rather than the default /usr/local/openssl, it finds the includes, the libraries, and the binaries that are needed. Then I specifically point the certs directory (in the Makefile) to /usr/local/openssl/certs for local control. Then, for the example of uw-imap, everything builds just fine. This should simply apply to anything we need to build with openssl on any of the T5220s. One side note is that this was a custom Makefile. Applications that use ./configure would presumably find the openssl through the paths provided in /usr/local/src/env. In the process of figuring that out, I also found that one of the most recent Solaris 10 kernel patches that we have on imladris specifically addresses awareness of the crypto accelerators and included patches to the openssl related items in /usr/sfw. So, I'm pretty confident that everything is alright. It's interesting too that in the paper presented at ACM by Sun last year they said that a couple of classes of attacks on crypto processes were negated by running it directly on the CPU. One of them had to do with timing. I should forward that paper to you as well. OK, just attached it. -- --------------- Chris Hoogendyk - O__ ---- Systems Administrator c/ /'_ --- Biology& Geology Departments (*) \(*) -- 140 Morrill Science Center ~~~~~~~~~~ - University of Massachusetts, Amherst <hoogendyk(a)bio.umass.edu> --------------- Erdös 4

[Dovecot] Post-login script with LDAP virtual users
by Hideo GOTO 16 Apr '11

16 Apr '11

Dear sirs, I'm working on Post-login script for migrating 40K Courier-imap users to Dovecot. After reading related topics about post-login script in your documentation, mailing list, I cannot remove the problem described here-below. Is there any special config to add when users are virtual (authentication and user info is fed by LDAP server). I would be grad if anyone could give me advise. Phenomena: ========== Although the authentication and script execution is successfully done, Pop3 session is aborted just after that, leaving the following error message to syslog: /var/log/maillog: Feb 7 17:45:58 pop3migr dovecot: pop3(vuser1): Post-login script denied access to user vuser1 cf. "vuser1" is UID of a virtual account on the LDAP tree. Maildir is located at /var/spool/postfixdata/%u/Maildir, and is owned by linux local user "mailuser". Dovecot works perfect ,if post-login script configuration is commented out. Environment: Dovecot: dovecot-2.0.9 (built from source tar ball) OS: Linux / 2.6.30.10-105.2.23.fc11.x86_64 (Virtual machine on a xen server) Maidir: tested both with local file system and NFS (ext3, xfs) client: Using telnet on pop3 TCP port. All the pop3 users are virtual and does not have local login account ('authentication and user information is given by LDAP server). SMTP service is managed by Postfix: ( A single local login account is writing all mails to Maildir for all the virtual users. ) Thanks in advance.

[Dovecot] How to purge mailboxes manually [dovecot_1.2.15]
by Emilio Nacelle 15 Apr '11

15 Apr '11

Hi, we have a linux network at the office. Mainly ubuntu and debian systems. Each user has it's own mail client, thunderbird, evolution, etc. In the mail server we use as the local delivery agent, dovecot 1.2.15 and the protocol imap. The users mailbox are in the server at /var/mail. Due to some kind of problem the mails that are set for delete in the mail client are not being deleted in the mailbox (if we check the mbox the mails are marked to be purged). Unless the owner uses something lowlevel shell mail client like pine to do the purge, the mails start to pile filling the account. Is this some known bug with a fix, or is there some routine we can run as admins to actually purged the mails set for deletion? (Like the "doveadm purge" in dovecot 2.0) Thanks a lot, looking forward to your answers, Emilio P.S: we would really like not having to install dovecot 2.0 :)

[Dovecot] Released Pigeonhole v0.2.3 for Dovecot v2.0.12
by Stephan Bosch 14 Apr '11

14 Apr '11

Hello Dovecot users, It's been a while since the last Pigeonhole release. This new release adds support for the new vacation-seconds extension, which allows the vacation extension to reply more frequently than every day and allows specifying this interval in seconds instead of days. I've also fixed quite a few bugs that were reported in the last couple of months. Changelog v0.2.3: * Sieve-filter tool: finished implementing basic functionality. It is not quite ready yet, but it is available for those willing to experiment with it (needs --with-unfinished-features config to compile). Also includes man page. + Vacation extension now inhibits replies to messages from sender listed in :addresses, thus preventing replies to one of the user's other known addresses. + Vacation extension: implemented the (draft) vacation-seconds extension. This also adds min/max period configuration settings. Refer to doc/vacation.txt for configuration information. - ManageSieve: fixed bug in UTF-8 checking of string values. This is done by discarding the original implementation and migrating to the Dovecot API's UTF-8 functionality. - Sieve command line tools now avoid initializing the mail store unless necessary. This prevents sievec and sieve-dump from failing when executed by root for example. - Enotify extension: fixed inappropriate return type in mailto URI parse function, also fixing ARM compiler warning. - Vacation extension: fixed handling of sendmail errors. It produced an additional confusing success message in case of error. - Removed header MIME-decoding to fix erroneous address parsing. Applies to address test and vacation command. - Fixed segfault bug in extension configuration, triggered when unknown extension is mentioned in sieve_extensions setting. The release is available as follows: http://www.rename-it.nl/dovecot/2.0/dovecot-2.0-pigeonhole-0.2.3.tar.gz http://www.rename-it.nl/dovecot/2.0/dovecot-2.0-pigeonhole-0.2.3.tar.gz.sig Refer to http://pigeonhole.dovecot.org and the Dovecot v2.0 wiki for more information. Have fun testing this new release and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

You'd need to find out what exactly is locking those mailboxes for that long. It could simply be the user's client. Or I guess it could be LDA itself, or anything really.. Difficult to say. Difficult also to tell easy way to debug this.. Or when this happens does it happen to many people at the same time? Is the system load really high at that time then?

[Dovecot] Login via IMAP with MySQL as user database not working
by Chris Martin 13 Apr '11

13 Apr '11

Hello all, I am migrating from Postfix/Cyrus/MySQL mail server to a recently installed dovecot 1.2.8 on a QNAP TS259 NAS via XDove. I am unable to login via IMAP (the only method I've tried and the only method I want). I am using an almost identical database as the current existing Postfix/Cyrus/MySQL setup (with the except of paths). I have been attempting to get this working (off and on) for the past 5 months. During that time I have researched and researched, but have not found a solution. The Maildir has been copied from the existing server to the Dovecot server and have run the script 'courier-dovecot-migrate.pl', which was found at http://www.dovecot.org/tools/courier-dovecot-migrate.pl In a nutshell: If I have the password_query string in the SQL config file (shown below) set to return only 1 field, i.e. the password, then the Dovecot authtest app succeeds. But if more than 1 field is returned (i.e.: user and password) the test fails. And if testing with telnet I get the message of "* BYE Internal login failure. Refer to server log for more information.". The logs indicate that the password check returned OK but the userdb read appears to fail. If I change the userdb_query to return only 1 field (such as only the uid), then the logs show the correct value is returned, and yet the telnet login fails. So it seems that anytime there are multiple fields returned from the SQL query, the result is failure at that step (password check or userdb read). Therefore userdb prefetch never works. The NAS doesn't utilize a syslog so it's of no help in debugging. Below are the config files and samples from log files (scrubbed): dovecot.conf- (NOTE: the 'home = /tmp' in the plugin section is an attempt at rawlog from http://wiki2.dovecot.org/Debugging/Rawlog ... which doesn't seem to work) # 1.2.8: /etc/dovecot/dovecot.conf # OS: Linux 2.6.33.2 i686 log_path: /var/log/dovecot/dovecot.log info_log_path: /var/log/dovecot/dovecot-info.log log_timestamp:

[Dovecot] Solaris 10 Compilation Issue with 2.0.12 (actually post 12690) [WORKAROUND PROVIDED]
by Peter Bray 13 Apr '11

13 Apr '11

Greetings, Post 12689:7f5735ab7c35 / 12690:02829f7f79c7 dovecot uses the reentrant version of get(password/group)* related functions. There are two variants of these functions on Solaris. To get the variant used by dovecot code based you need to define _POSIX_PTHREAD_SEMANTICS (see attached manual page). Initially I defined this just for the compilation of lib/src/ipwd.c, and got the code to compile / check / run successfully in my environment. After this worked I decided to try compiling the whole code base with CPPFLAGS="-D_POSIX_PTHREAD_SEMANTICS" ./configure .... This also seems to work fine. My environment uses IMAPS (X86) and Proxying IMAPS (SPARC). All code compiles / checks / runs (only 64-bit versions run tested) with the above CPPFLAGS modification on Oracle Solaris 10 Update 9 (both 32/64 bit on both X86 / SPARC with GCC 4.1.2) systems. Regards, Peter Bray Sydney, Australia PS: I have not investigated an appropriate way to modified configure.in to make this addition automatic.

Multiple > deliveries are useful only if you want to try to get the same mail file > hard linked to all recipients. So normally this is a non-issue. I guess my sendmail is not normal. The default configuration does pool multiple recipient delivery and run mail.local with all these users as arguments in one invocation. dovecot-lda doesn't seem to support multiple recipients per invocation, so this won't be a problem. The implication for sendmail users, though, is that multiple concurrent deliveries must be disabled if you use dovecot-lda (the 'm' flag must be removed from LOCAL_MAILER_FLAGS) as implicitely done in http://wiki2.dovecot.org/LDA/Sendmail I notice the 'A' flag is missing here: doesn't this kill aliasing?

[Dovecot] Questions about converting maildir to mdbox.
by Henrique Fernandes 12 Apr '11

12 Apr '11

First of all i would like to thanks Timo for the excellent job done in dovecot. We are using it in you prodution server with about 5 millions of emails and it is pretty good, only a performance problens but i guess it is realated to ocfs2 that we are using. So lets begin: We are using dovecot 2.0.6 with maildir in an ocfs2 partiton. It is pretty slow access in peak time, but it is related to ocfs2 as i said before, i am trying to mimimize the ocfs2 latancy by using mdbox. Another problem that we have are Full backup that takes about 24h and incremental takes about 13h I am thinking in converting some email for testing propose, but i am wondoring how would dovecot convert this, like if i convert all mail from maildir to mdbox it would make many mailbox based on this seetings ? Or in the first convert it would make a big mdbox file and after it it will rotate by day or it would make many boxes just based on size? mdbox_rotate_size = 5m mdbox_rotate_interval = 1d Well, another thing can i make rotate interval happens in a certain time of day? end from where it takes this time ? it rotates at midnight ? Another one!, if i lose the index files what really happens ? Sometimes in my server the index get corrupet and as i am reading mdbox index files held information that is not in other place. So what should i do to prevent any possible lose of data even if i lose the indexes? I was reading about backup restore also, but i did not get it pretty well. With maildir we simple restore the files and the index gets rebuilt! What should i do with mdbox ? Restore the files and the index ? But how about the other emails that the account got after the backup, how i should merge the multiple files and more importanet how do i merge the index files ? Well, sorry about my english! And Thanks alot guys! []'sf.rique

[Dovecot] Vpopmail and lastauth
by mailing＠securitylabs.it 12 Apr '11

Hello, I'm migrating many accounts to a new server with vpopmail 5.4.33 and dovecot 2.0.11. I've already vpopmail 5.4.32 and dovecot 1.2.16 on others servers running without problems. With dovecot 2.0.11 my lastauth file is not updated. This file usually is update on any access (smtp, pop3, imap) with the client's IP, for every mailbox. Now it's updated only when a client authenticate itself via SMTP (smtp-auth with qmail + vpopmail), and not with imap/pop3 access.

[Dovecot] SUMMARY: LDA vs LMTP, Cyrus SASL, verbose_proctitle
by Joseph Tam 12 Apr '11

12 Apr '11

A summary of answers I got to the questiosn I posed. > Is there a reason I should prefer LMTP over LDA for local delivery? Thanks for the responses I received. The benefits reported were more/better information logging, and service isolation. Also, one significant advantage not mentioned for LMTP was that one delivery failure to multiple recipients can be disambiguated; LDA can only return an exit code to be tested by the MTA, but the MTA cannot know which recipient(s) generated the error. This problem present can itself, for example, when one user has a full mailbox. An LDA will return EX_TEMPFAIL, and the message will be requeued, and delivery will be retried for all recipients (even those that were successfully delivered to). > The Wiki doesn't differentiates LMTP vs LDA with respect to sendmail > configuration, so am I correct that I just need to replace mail.local > with dovecot-lda, which will choose LDA/LMTP based on dovecot.conf? Not that simple, but I finally did find my answer in the Dovecot archives. It's too bad I had to spend hours tearing apart the sendmail docs before finding it http://www.dovecot.org/list/dovecot/2010-September/052936.html The .mc version of the configuration: # Use LMTP for local delivery over IPC channel FEATURE(`local_lmtp',`[IPC]') # Location of LMTP socket define(`LOCAL_MAILER_ARGS', `FILE /path/to/dovecot/lmtp') # Replace default sendmail LMTP options: the same options # with the 'P' flag removed so that the Return-Path is not # added (again?) define(`LOCAL_MAILER_FLAGS', `SXmnz9') MAILER(`local') I haven't tried this yet, but this is pretty close. > Also, can I consolidate authentication by configuring dovecot to use > what sendmail uses (Cyrus SASL) or vice versa? The Wiki hints this is > in the works. No response, so I guess the answer is no. > Lastly, toggling verbose_proctitle seems to have no effect on the output > of ps. Is verbose_proctitle broken for Solaris? The answer to is verbose_proctitle is broken for Solaris. There is no setproctitle(), and ps does not report changes to a process's argv[]: echo "main(int c,char**v){**v='x';sleep(9);}" | \ gcc -xc -o y -; ./y; rm y & ps -f You'll have to use "lsof", "pfiles" or "doveadm who" to get the information.

[Dovecot] trying to combine static userdb with LDAP passdb with per-user userdb_mail and userdb_home
by Igor Zinovik 12 Apr '11

12 Apr '11

Hello, dovecot users. I'm trying to cope with following problem I have single computer which will be going to be final destination for several virtual domains. Domains are stored in LDAP catalog. Dovecot will be working together with Postfix MTA running on same computer. I'm a bit confused how to achieve following thing: I want Postfix to use Dovecot LMTP server for mail delivery. All my mail is located under /var/vmail partition. I designed my own ldap schema and according to dovecot documentation that user should always has home and mail directory i added separate attributes for user home and mail. My typical user that is stored in LDAP has homeDirectory (which stores value like /var/vmail/domain.com/j/joe) and mailMessageStore (which stores value like /var/vmail/domain.com/j/joe/Maildir). All data under /var/vmail is owned by Postfix MTA user (which is called `postfix', uid=89). After reading dovecot documentation I understand that my setup needs to combine static userdb with LDAP passdb. But i also want dovecot to be able to deliver mail for local system users (that are stored in /etc/passwd). For system users i want to store their mail in $HOME/Mail. So i set mail_location = ~/Mail (which turns into /home/user/Mail), but for virtual (which are stored in LDAP) users i want to set mail (or maybe i should write here userdb_mail) to LDAP value mailMessageStore. Seems to me that LMTP server needs separate userdb query to fetch mail_location from LDAP. Setting mail_location = /var/vmail/%d/%n1/%u solves my problem, but I want dovecot to dynamically fetch maildir location from LDAP. Maybe in near future I would also store mail somewhere else not only under /var/vmail. And dovecot will fetch this information from LDAP.

Should i just add two attributes to each LDAP user like mailuid and mailgid and set both these variables to `postfix'. Or maybe i should just forget about mail for local system users and just user `prefetch' userdb. I'm just mazed about dovecot userdb and passdb queries. It so powerful but also so hard to understand. I would appreciate any help, since I peck dovecot authentication and userdb-passdb queries like woodpecker starting from last week. Do I understand right that dovecot during userdb fetches Unix UID which will be used to access data on disk? I just want postfix (uid=89) to allow to do this.

Re: [Dovecot] IO rate quotas?
by Alan Brown 12 Apr '11

12 Apr '11

From: Timo Sirainen <tss(a)iki.fi> Subject: Re: [Dovecot] IO rate quotas? > So a single process that is reading files fast enough from disk can > cause disk IO to spike in a way that makes all other processes wait for > available disk IO? It's not a single process. Thunderbird's newest defaults are to syncronize every folder and it will open one connectrion per folder in order to do that. Appropriate disk/swappiness/readahead/cache tuning is required - along with enough ram to cope with several users trying this at once. The underlaying filesystem is also important. as a for-instance, this kind of load with maildir format will effectively _kill_ a GFS box. Our fix was to install systemwide defaults on managed systems to not synchronize (not needed, the home directories are on network storage anyway) and to ask people to check/unset this on laptops/etc

[Dovecot] domain variable still empty
by Andre Rodier 11 Apr '11

11 Apr '11

Hello all, First, thanks for your help with my previous NFS problem. I am trying to mount a mail server, with debian and dovecot 1.2. Until now, I have both shared and public folders working, on a NFS share. indexes are stored locally, as well as per user flags. Sive is also working :-) Now, I'd like to restrict sharing by domain, and for this, to use the "%d" variable When I authenticate, for instance using arodier@red2team, the authentication works. However, the "%d" variable is still empty, when I'd like it to contains "red2team" Here my config: -------------------------------------------------------------- # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-amd64 x86_64 Debian 6.0.1 nfs4 log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps managesieve ssl: required disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(managesieve): /usr/lib/dovecot/managesieve-login login_greeting: Titan Ready mail_access_groups: mails mail_privileged_group: mails mail_uid: vmails mail_gid: mails mail_location: maildir:/home/emails/%d/%n/Maildir:INDEX=/var/mail/indexes/%n:CONTROL=/var/mail/indexes/%n mail_debug: yes mmap_disable: yes fsync_disable: yes mail_nfs_storage: yes lock_method: flock mbox_write_locks: fcntl dotlock mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(managesieve): /usr/lib/dovecot/managesieve mail_plugins(default): quota imap_quota acl imap_acl fts fts_squat mail_plugins(imap): quota imap_quota acl imap_acl fts fts_squat mail_plugins(managesieve): mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(managesieve): /usr/lib/dovecot/modules/managesieve namespace: type: private separator: / location: maildir:/home/emails/%d/%n/Maildir:INDEX=/var/mail/indexes/private/%n:CONTROL=/var/mail/indexes/private/%n inbox: yes list: yes subscriptions: yes namespace: type: shared separator: / prefix: Shared/%%u/ location: maildir:/home/emails/%d/%%n/Maildir:INDEX=/var/mail/indexes/users/%n/%%n:CONTROL=/var/mail/indexes/users/%n/%%n list: children namespace: type: public separator: / prefix: Team/ location: maildir:/home/emails/%d/Public/Maildir/:INDEX=/var/mail/indexes/public/%n list: yes lda: postmaster_address: postmaster(a)red2group.com hostname: smtp1.red2group.com mail_plugins: quota acl sieve auth_socket_path: /var/run/dovecot/auth-master auth default: mechanisms: plain login default_realm: red2team username_format: %u verbose: yes debug: yes passdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf userdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 438 plugin: quota: maildir acl: vfile:/etc/dovecot/acls/:cache_secs=300 acl: vfile acl_shared_dict: proxy::acl sieve: /home/emails/%d/%n/Filters/Active.sieve sieve_dir: /home/emails/%d/%n/Filters fts: squat dict: quota: ldap:/etc/dovecot/dovecot-ldap.conf acl: mysql:/etc/dovecot/dovecot-mysql.conf -------------------------------------------------------------- This is now the content of the dovecot-ldap config -------------------------------------------------------------- auth_bind = yes base = dc=red2,dc=srv default_pass_scheme = PLAIN-MD5 hosts = callisto.red2.srv thebe.red2.srv ldap_version = 3 pass_filter = (&(objectClass=posixAccount)(uid=%n)) scope = subtree user_attrs = homeDirectory=home,gosaMailQuota=quota_rule=*:storage=%$M, mail_plugins user_filter = (&(objectClass=posixAccount)(uid=%n)) -------------------------------------------------------------- What surprise me is this line during the authentication: ===> auth(arodier(a)red2team,10.10.2.19): username changed arodier@red2team -> arodier Any idea, please ?

[Dovecot] INBOX empty after dsync
by Gary Chodos 11 Apr '11

11 Apr '11

After hearing so many good things about mdbox, I am testing it. I moved my Maildir to a test box, and did the conversion with dsync which reported no errors and appeared to go fine after I set: namespace { separator = / inbox = yes } and changed mail_location=mdbox:~/mdbox But the problem is that the Inbox now is empty in my imap client. What did I do wrong? I can see the emails are there if I grep for subject lines I know exist in my inbox within ~/mdbox, but in the imap client it is as if inbox is totally empty. All the other folders appear fine in imap client.

[Dovecot] Dovecot 2.0 config bug with SSL certificate per protocol?
by Andy Smith 09 Apr '11

09 Apr '11

Hi, yesterday I upgraded Dovecot from 1.2 to 2.0.11. I'd seen that there was a config file converter to make the upgrade smooth so was expecting it to be pretty quick and easy. In the end I spent a long time trying to get it working as it just wouldn't listen on the ssl ports, imaps and pop3s. I am using per portocol SSL certificates, as I was in version 1.2. The part of my config is as follows (as generated by doveconf): protocol imap { imap_client_workarounds = delay-newmail tb-extra-mailbox-sep mail_plugins = fts fts_squat ssl = yes ssl_cert = </usr/local/etc/ssl.crt/imap.crt ssl_key = </usr/local/etc/ssl.key/imap.key } protocol pop3 { pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_uidl_format = %08Xu%08Xv ssl = yes ssl_cert = </usr/local/etc/ssl.crt/pop3.crt ssl_key = </usr/local/etc/ssl.key/pop3.key } But when I started dovecot it was only listening on the non SSL ports for IMAP and POP3. I went through many things, adding in a service imap-login section with the SSL port set via inet_listener and spent ages googling for how to get it to work. In the end it turns out it was that the global ssl setting was set to "no", but I hadn't enabled this previously as this requires that there are global SSL certificates, which I don't have; I have specific certs for IMAP and for POP3. Also this isn't how dovecot 1.2 worked, there I specificed the protocols (pop3, pop3s, imap, imaps) and specificed the protocol certs and it worked. Anyway, I ended up just specifiing my pop3 certs as the global certs, this is then redefined in the pop3 protcol section etc. The config seems to work, but to me all this doesn't seem logical and doesn't work like in dovecot 1.2. Maybe this is something that can be cleaned up in the next version? thanks Andy.

[Dovecot] IO rate quotas?
by Kádár Tamás (KTamas) 09 Apr '11

09 Apr '11

Hi Okay so we've been having this issue since forever and I figured why the heck not ask it here since it's mostly related to dovecot. The thing is, we have a huge amount of public folders (at the moment, around 1100). Now, with dovecot indexing and caching we're mostly okay, also being careful with things like Thunderbird 3's default 'Download everything' option ("Keep messages for this account on this computer") and such. However once in a while, someone goes rogue, we install a new version of thunderbird, someone accidentally sets up an email account in thunderbird mistakingly leaving the download everything option on. This causes high IO on our server, and a single user can quickly more or less kill the whole server in mere minutes, load average quickly spiking to 30-40-50 and everything becomes sloooooow (obviously). Is there any way I can limit the amount of IO a certain user can use? Thanks and best regards, KT P.S. my dovecot -n is: # 2.0.9: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 2.6.26-2-xen-amd64 x86_64 Debian 5.0.8 auth_mechanisms = plain login disable_plaintext_auth = no listen = * mail_location = maildir:~/Maildir mail_plugins = acl maildir_very_dirty_syncs = yes namespace { inbox = yes location = prefix = separator = . type = private } namespace { location = maildir:/home/_shared/projects:INDEX=~/Maildir/_shared prefix = shared. separator = . subscriptions = no type = public } namespace { location = maildir:/home/_shared/sys:INDEX=~/Maildir/sys prefix = sys. separator = . subscriptions = no type = public } passdb { driver = pam } plugin { acl = vfile mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename flag_change append mail_log_fields = uid box msgid from subject size vsize flags mail_log_group_events = no } protocols = imap pop3 service imap { executable = imap } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } verbose_proctitle = yes protocol imap { mail_max_userip_connections = 40 mail_plugins = acl imap_acl }

This will be opaque to the user, but I don't think it will happen often so it's no bother to find the problem in the logs. Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] Imap segfault on login with version 2.0.8 & 2.0.11
by Nicholas VonHollen 09 Apr '11

09 Apr '11

Hi everyone, I'm trying to upgrade/test our configuration files from Dovecot 1.2 to 2.0.11. I used the Dovecot config convert command, created a RHEL 5 x86_64 rpm, and tested it. I can connect, but once I login, the IMAP service segfaults. I've also reproduced this on version 2.0.8. I installed the debug RPM (for the stripped symbols), took a look at the core dump in gdb, and just got the _start method in ld_preload and a broken pointer in the backtrace. I tried to strace everything but the segfault doesn't happen then :-). I'm not sure what to do to get better information. I attached my client session, dovecot -n output, gdb trace, maillog, and the core dump. I published the RPMs I made at: http://c3205012.r12.cf0.rackcdn.com/dovecot-2.0.11-1_125.x86_64.rpm http://c3205012.r12.cf0.rackcdn.com/dovecot-debuginfo-2.0.11-1_125.x86_64.r… My platform is RHEL 5 with kernel 2.6.18 on x86_64. Is there anything else I can provide for more info? Thanks, Nick Nick VonHollen Rackspace Software Developer Desk: 540-443-2003 (internal 505-2003) Personal Cell: 757-710-7038

[Dovecot] restarting director
by Cor Bosman 08 Apr '11

08 Apr '11

Hi all, anyone having any problems with restarting the director? Every time I bring down 1 of the director servers, reboot it, or just restart it for whatever reason, im seeing all kinds of problems. Dovecot generally always gives me this error: Jan 20 22:49:55 imapdirector3 dovecot: director: Error: Director 194.109.26.173:444/right disconnected before handshake finished It seems the directors cant agree on forming a ring anymore, and this may be leading to problems with clients. I mostly have to resort to bringing down all directors, and restarting them all at once. Not really a workable solution. As an example, last night for a few hours we were getting complaints from customers about being disconnected, and the only obvious error in the log was the one above, after one of my colleagues had to restart a director because of some changes in the syslog daemon. After I restarted all directors withing a few seconds of each other, all complaints disappeared. Timo, i know ive asked similar questions before, but the answer just eludes me. If I have 3 director servers, and need to take one down and restart it, what is the proper method to reconnect the ring? In practice, I cant seem to work it out and I mostly end up with the above error until I just restart them all. Not fun with 20.000 clients connected. Cor

[Dovecot] Thunderbird 3.1 unable to delete subfolder of Trash under mdbox
by William Blunn 08 Apr '11

08 Apr '11

Thunderbird 3.1.9 over Windows 7. Dovecot 2.0.11 (2:2.0.11-0~auto+41 from http://xi.rename-it.nl/debian/ source on 8 Apr 2011) over Ubuntu 10.04 LTS. Trying to set up a Dovecot system with mdbox. But I also wanted to keep some Maildir. So I ended up with both mdbox and Maildir side-by-side and noticed an issue. On this system, Dovecot's global mail location is configured with maildir:~/Maildir I have a two users configured in a password-file passdb/userdb: One using the Dovecot global mail location (maildir:~/Maildir) the other with an override mail location (userdb_mail) of mdbox:~/mdbox (The only other configurations different to the default were to turn off the default system password passdb and userdb, and enable my local password-file-format passdb and userdb.) I have configured two IMAP accounts in Thunderbird 3.1.9, one to access each of the two users above. The test procedure is: In Thunderbird, create a folder at the top level (i.e. alongside Inbox), say "foo". In Thunderbird, delete the folder just created. This results in Thunderbird "moving" the folder to "Trash", resulting in a folder "Trash/foo". Up to this point, both the Maildir and mdbox users behave OK. Then in Thunderbird, delete the trashed folder "Trash/foo". At this point, things start to happen differently. With the Maildir user, the folder "Trash/foo" deletes successfully. But with the mdbox user, Thunderbird pops up an error: The current command did not succeed. The mail server for account <accountname> responded: Invalid mailbox name: Trash/foo/. The folder does disappear from the Thunderbird folder pane, but if Thunderbird is "prodded" to refresh what folders it thinks are there, then the folder reappears. If we check the user's mdbox directory, we can see that indeed the mailbox has not been deleted. Whatever I then do, I am unable to delete this folder in the mdbox user through Thunderbird. The only way I have found to safely delete the folder is to use "doveadm mailbox delete", but this requires root privilege on the server, which is not really a practical solution. It maybe a Thunderbird problem, but the question then arises: Why does it work under Maildir but doesn't work under mdbox? Any ideas? Bill

[Dovecot] fstat no such file or directory error
by Mark Dieterich 08 Apr '11

08 Apr '11

Periodically, we will have users IMAP sessions get hung. Their client sees a message like: The server responded: 'SERVERBUG] Internal error occurred. Refer to server log for more information On the server, we see the following in the logs: IMAP(<username>): Transaction log dovecot.index.log: duplicate transaction log sequence (37) IMAP(<username>): fscking index file dovecot.index IMAP(<username>): fstat() failed with index file dovecot.index: No such file or directory After the fstat message shows up, there doesn't appear to be anything on the user side that can be done to fix the problem. We've seen multiple instances where the file dovecot is complaining about not existing is visible, readable, and writable by the user in question, but dovecot is convinced it's not. The only way we've found to fix this issue is to kill off all user connections. When the user reconnects, then all appears to work fine. We have not found a way to recreate this problem. Some details: # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.26-2-686 i686 Debian 5.0.8 Mail files are stored on NFS. All imap connections for a given user are are mapped to a particular server at any given time. We have a script in place that watches our logs for this order of events, so the problem self corrects relatively quickly. But it would certainly be nice not have this happen at all. Thanks, Mark -- ---------- I'd rather be burning carbohydrates than hydrocarbons
