Postfix doesn't allow external hosts to connect & relay mail, which explains what you're seeing. Why you're seeing that is better addressed on the postfix list, although you seem to have told postfix to use Dovecot for sasl auth, so maybe, since this is the Dovecot list you should send your Dovecot conf so we can see why it's not working. Also, if you ask on the postfix list you will be asked for the out-put of postfinger which can diagnose sasl problems. Simon

[Dovecot] Update 1.2 -> 2.0 ... INBOX away?
by Martin Rabl 29 Dec '12

29 Dec '12

Hi, yesterday I did an update from dovecot 1.2 to 2.0.19 (Ubuntu 10.04 -> 12.04). After fixing the configuration dovecot startups as it should, but with one error, I don't understand: the INBOX will not be delivered to the Mailclient and will not be filled by "deliver". Instead, dovecot create the two dirs "new" and "cur" directly in "Maildir". the filesystem looks now like: domain/user1/Maildir/INBOX # official INBOX domain/user1/Maildir/new # new mail domain/user1/Maildir/cur # read mail We have searched for an configuration error, but didn't found anything - or did not see one ;-) Maybe there is someone in the list, which see our error in a moment? We are using only imap/s and managesieve, no pop3. Maildir-Layout is FS. Here a snippet of our configuration: ------------ mail_home = mail_location = maildir:~/Maildir:LAYOUT=fs namespace { hidden = no inbox = yes list = yes location = prefix = separator = / subscriptions = yes type = private } namespace { list = yes location = maildir:%%h/Maildir/:INDEX=%%h/Maildir/shared/%u:LAYOUT=fs prefix = shared/%%u/ separator = / subscriptions = no type = shared } namespace { list = yes location = maildir:/srv/vmail/public:LAYOUT=fs prefix = public/ separator = / subscriptions = no type = public } protocol lda { mail_plugins = sieve autocreate } protocol imap { imap_client_workarounds = delay-newmail tb-lsub-flags tb-lsub-flags mail_max_userip_connections = 10 mail_plugins = acl autocreate imap_acl } ------------ Hope you can help! Thank you! Martin

[Dovecot] question

I just install Dovecot and postfix. When I'm pull dovecot I see in the log that its checking for mail. if a put a test message locally on the server I can pull the message down to my cell phone and other computers. But when I try to a message from gmail or aol it doesn't come in to the server. it always bounces back to the place were I sent it from

[Dovecot] mdbox: more then one altstorage
by Peer Heinlein 28 Dec '12

28 Dec '12

The mdbox-format with the altstorage-feature is quite nice and important. But we're having much more then >> 30 TB of maildata and doing an fsck on huge partitions takes too much (down-) time for our mailsystem. It would be much easier, if Dovecot would be able to use at least THREE storage-paths for his m-Files (and not just TWO like now). Having an altstorage1 and altstorage2, we would be able to move away all mails from on altstorage-mountpoint, we could put this storage-moungpoint into "maintenance" and do an fsck without Downtime for Dovecot. It would be nice having a doveadm-feature to put a altstorage-path in "maintenance-mode", so to move easily away all m-files to other alt-storage-paths and to let Dovecot know not to use this locked partition. Having even more then 3 storage-paths would be nice for huge setups: In this case we could easily use different SMALLER partitions without having just two or three huge partitions > 15 TB. The architecture of the altstorage-system is nice and simple. Wouldn't it be easily possible to look (at least) in three, then just in two places for a m-file? What about a "hash_dir"-system for the storage? What about a configuration-parameter like altstorage_dirs=4 which would mean, that there are 4 storage-mountpoints that could be addressed by "%m": mail_location = mdbox:/vmail/%d/%n/mdbox:altstorage/alt/%m/%d/%n In this case, Dovecot could easily use all existing partitions automatically "round-robin". Or maybe it would be better to tell Dovecot the partitions by: altstorage_dirs_existing = 1,2,3,4 altstorage_dirs_newmail = 1,4 so it would be very easy to tell Dovecot in which partitions he has to look for m-files and where he is allowed to save round-robin new e-mails. With this setup it's easy to put a partition in maintenance mode.

[Dovecot] Mixing v2.1 and 2.0 directors ?

I'm preparing to set up a new set of directors on dovecot-ee-2.1.10.3-1, but would prefer to do this a bit gradually. Will it be OK to set up a ring of directors with 2x dovecot-ee-2.1.10.3-1 and 2x dovecot-2.0.14 ? -jf

[Dovecot] dovecot testinstallation does not tell how to quit
by Robert Moskowitz 28 Dec '12

28 Dec '12

I am having problems logging in with RoundCube, so thought I should see if there were instructions for testing Dovecot login, and sure enough I found some at: wiki.dovecot.org/Testinstallation Well it works, so the problem is probably all RoundCube's, but this wiki page is missing an important line about how to end the Telnet session without killing Telnet! What is the quit/exit command? And please add this to the wiki! Oh, I just guessed it: a logout

[Dovecot] Using -module flag on sieve libs
by Dimitri 26 Dec '12

26 Dec '12

Some modern distros (Mageia, Mandriva) use -no-undefined as a default linker flag for building software. However, undefined symbols are OK if the binary being linked is a plugin. To detect plugins, build system looks for presence of "-module" libtool flag in makefiles. There are two libraries in Pigeonhole that couldn't be linked with -no-undefined: src/lib-sieve/plugins/mailbox/libsieve_ext_mailbox.la src/lib-sieve/libdovecot-sieve.la These modules do contain undefined symbols, but they are not linked against library that provides them. It would be good if corresponding makefiles contained "-module" flags, so that build system could selectively turn off that -no-undefined linker flag. Please see proposed patch (attached). Thanks, Dimitri Mageia Linux packager

[Dovecot] Postfix/mysql/dovecot - Understanding password encryption
by Robert Moskowitz 25 Dec '12

25 Dec '12

I am switching from a fedora/postfix/mysql/couriermail/squirrelmail to Centos/.../dovecot/roundcubemail and adding postfixadmin to the mix. My tutorial before was an earlier version (on F14) of: http://www.howtoforge.com/virtual-users-and-domains-with-postfix-courier-my… Now I am using http://www.campworld.net/thewiki/pmwiki.php/LinuxServersCentOS/Cent6VirtMai… to get me started. I am up to roundcubemail setup and am stumbling to understand what the author here is doing with encrypted passwords, so felt it was time to delve deeper into this. My old setup uses mysql-crypt for the password. MYSQL_CRYPT_PWFIELD password and users could be added to the table with: INSERT INTO `users` (`email`, `password`, `quota`) VALUES ('sales(a)example.com', ENCRYPT('secret'), 10485760); But where this was all simple and no choices, I get to figure out what to do with my dovecot setup. Some of the 'secret' is hinted at in postfixadmin's config.inc.php: // Encrypt // In what way do you want the passwords to be crypted? // md5crypt = internal postfix admin md5 // md5 = md5 sum of the password // system = whatever you have set as your PHP system default // cleartext = clear text passwords (ouch!) // mysql_encrypt = useful for PAM integration // authlib = support for courier-authlib style passwords // dovecot:CRYPT-METHOD = use dovecotpw -s 'CRYPT-METHOD'. Example: dovecot:CRAM-MD5 $CONF['encrypt'] = 'md5crypt'; Where is there information on the different choices and how to choose. Is it as 'simple' as setting up postfixadmin to control the password encryption format then 'inform' dovecot in the dovecot-mysql.conf with default_pass_scheme = MD5-CRYPT Thank you for any pointers.

[Dovecot] Understanding Sockets
by Tim Smith 22 Dec '12

22 Dec '12

Hi, Just trying to consolidate my knowledge of Dovecot and I want to understand various things rather than just key out lines of config in dovecot.conf with the hope of it working. What I wanted to clarify is my understanding the "socket listen" section of the config file. From my limited understanding, this section details how other processes can access the userdb defined in Dovecot. The master socket is used for "internal" processes which is mainly dovecot-lda so that when Dovecot receives mail it knows where to deliver it and client is defined for "external" processes, for example Postfix who would use the info to determine if a user existed. Would you say this is a fair (albeit) dumbed down!!) synopsis of sockets and their purpose? Thanks in advance! Tim

[Dovecot] Non-dovecot user looking for feedback
by Chris Ross 21 Dec '12

21 Dec '12

I've been using UW-IMAPd for neigh on forever (at least since 2001). But, as it's basically stalled, and I'm about to update the hardware that is my mail server, I thought it was time to review existing open-source IMAP servers. Dovecot is the top three in my looking. The other of the top three candidates, because I know of people who've used it, is Cyrus IMAP. So, I should note that my thoughts are "uw-imapd, because I already know how to use it", "Cyrus, because someone I know/trust liked it years ago", and dovecot, because "it seems stable, professional, and to meet all of my needs". I guess the biggest question I have is how files/folders are stored in the filesystem. uw-imapd has a "mbx" format that all of my folders are in, and also has support for mbox and maildir (i think). mbx had some advantages for speed access, which would be unimportant I assume with dovecot's indexes, but IIRC there was also some reason the mbox format coped poorly with multiple clients accessing the same folder at the same time. So, am I right that dovecot supports only the "one big full file" mbox format, and the maildir format? And if so, is it known to allow multiple simultaneous IMAP clients to access and monitor and/or modify the same folder simultaneously? After those questions, it's just a "what do you think the pros and cons of each are?" I know asking in this forum, that I will get most if not all votes for Dovecot. And that's fine, as long as you have specific reasons why it would be better for someone with only a handful of users and minimal time available to administer the systems in question. Thanks! I appreciate any and all feedback. - Chris

[Dovecot] backtrace from postgres dict
by Steffen Kaiser 20 Dec '12

20 Dec '12

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, since I enabled ACLs I get following backtrace. It looks like that it happens if the ACLs had been changed only. Also, it looks like that it always happens 1 minute after last "dict: Info: pgsql(localhost): Connected to database dovecot", no matter if the user is logged in (and idle) or logged off. Postgres logs: "could not receive data from client: Connection reset by peer" and "unexpected EOF on client connection". Is there some TCP keep alive issue? Postgres is using the "system default" for TCP keep alive. I'm currently testing ACLs via telnet, so the activity with the ACL dict is pretty low, hence, an idle timeout would make much sense. # ../../sbin/dovecot --version 2.1.10 (a4f02f6c0d32) dict connect string: connect = host=localhost dbname=db user=user 2012-11-28 10:03:39 dict: Info: pgsql(localhost): Connected to database dovecot 2012-11-28 10:03:39 dict: Info: pgsql(localhost): Connected to database dovecot 2012-11-28 10:03:39 dict: Info: pgsql(localhost): Connected to database dovecot 2012-11-28 10:03:58 IMAP(user) [22922]: Info: Disconnected: Logged out in=23 out=763 2012-11-28 10:04:41 dict: Panic: file driver-pgsql.c: line 84 (driver_pgsql_set_state): assertion failed: (state == SQL_DB_STATE_BUSY || db->cur_result == NULL) 2012-11-28 10:04:41 dict: Error: Raw backtrace: /usr/local/dovecot-2.1.10/lib/dovecot/libdovecot.so.0(+0x4857a) [0x7f91f511157a] -> /usr/local/dovecot-2.1.10/lib/dovecot/libdovecot.so.0(+0x485c6) [0x7f91f51115c6] -> /usr/local/dovecot-2.1.10/lib/dovecot/libdovecot.so.0(i_error+0) [0x7f91f50e4eaf] -> dovecot2.1/dict() [0x40aa36] -> dovecot2.1/dict() [0x40aa91] -> dovecot2.1/dict() [0x40bed3] -> dovecot2.1/dict() [0x409504] - -> dovecot2.1/dict(sql_db_cache_deinit+0x20) [0x408a60] -> dovecot2.1/dict(main+0x169) [0x405a59] -> /lib/libc.so.6(__libc_start_main+0xfd) [0x7f91f4b5cc8d] -> dovecot2.1/dict() [0x404bb9] 2012-11-28 10:04:41 dict: Fatal: master: service(dict): child 22923 killed with signal 6 (core not dumped) - -- Steffen Kaiser -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQEVAwUBULXbiGoxLS8a3A9mAQI9Ywf/YItPO4fFT70HcuwCkDXgx0Sn7CEyXu2j +1VzOu3R/TMs1rcxYJIvWiei6Nk3wXywzQl84POadJn61Yf2NuT80nMxwBsBbgio e+0oRE9JNVSjtvX5l7kehEdUDQjqRRKyrhWG9KDlpjWidGsYh7pQg0rDtp3UwG57 HuSBMiBAZ9t9sC2DXjn9wT9vweH3gMIhc/K5U0BLF5JG/K8UAKc5QBUgezjIYzvn KP90TJ4RoZ2vnPzmWfeIsjffRBvvC6UUgWmU02e2H9xJxzF32Nix0s8YWi7G91sH Ei057HW5NsKNDtp6B5fYk+xCpC6ucQiwFSr/ZG+uZCAdtTd2qmf60g== =tQYK -----END PGP SIGNATURE-----

[Dovecot] Problems trying to add dspam delivery to dovecot LDA to working Postfix/Dovecot server. No passdb.
by Brian Jarrett 20 Dec '12

20 Dec '12

Hello list, I'm really hoping someone can point me in the right direction on this. I set up a server using Postfix with LDAP lookups to Active Directory. Postfix delivers to maildir. Dovecot IMAP and POP are working correctly using PAM Kerberos to authenticate via Active Directory. I want to add spam filtering, so I'm trying to set up Postfix to use dspam which is then supposed to use Dovecot LDA to deliver messages to the mailbox instead of having Postfix deliver to the Maildir. I can't get any deliveries to Dovecot LDA to get past passdb lookup. When I run /usr/lib/dovecot/deliver -f bjarrett(a)garfield16.org -d bjarrett(a)metcalfexcavation.com I get: Dec 19 20:57:55 mxserver2 dovecot: auth: Debug: master in: USER#0111# 011bjarrett(a)metcalfexcavation.com#011service=lda Dec 19 20:57:55 mxserver2 dovecot: auth: Debug: password( bjarrett(a)metcalfexcavation.com) passdb doesn't support credential lookups Dec 19 20:57:55 mxserver2 dovecot: auth: Error: static( bjarrett(a)metcalfexcavation.com) passdb doesn't support lookups, can't verify user's existence Dec 19 20:57:55 mxserver2 dovecot: auth: Debug: master out: FAIL#0111 Dec 19 20:57:55 mxserver2 dovecot: lda: Error: user bjarrett(a)metcalfexcavation.com: Auth USER lookup failed Dec 19 20:57:55 mxserver2 dovecot: lda: Fatal: Internal error occurred.

[Dovecot] namespace subscription problem
by Holger Hegmanns 19 Dec '12

19 Dec '12

Hi all, my problem seems to be a cosmetic one (again). According to the docs: subscriptions: "yes" (default) if this namespace should handle its own subscriptions. If "no", then the first parent namespace with subscriptions=yes will handle it. Therefore is no way to create the following scenario: three namespaces (private, shared, public) the private namespace has to handle its own subscriptions the private namespace setup with "prefix = INBOX." the both shared and public namespace setup with "subscriptions = no" cause there is no so called "parent" namespace. Private namespace setup with "prefix = " works fine, but that's not what I want. namespace { type = public separator = . prefix = public. location = maildir:/var/spool/dovecot/vmail/public subscriptions = no } namespace inbox { type = private separator = . prefix = INBOX. inbox = yes } namespace { type = shared separator = . prefix = user.%%u. location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u subscriptions = no list = children } Any chance that the private namespace can subscribe to shared mailboxes with the principals above? ... Few hours later. Added a default namespace without any prefix: namespace { prefix = separator = . hidden = yes subscriptions = yes } Subscriptions works as expected, but when I telnet to dovecot now the LSUB command shows all boxes beneath the INBOX as well as without the prefix: b lsub "" * * LSUB () "."

[Dovecot] migration to dovecot pop3
by Rajesh M 19 Dec '12

19 Dec '12

hi i am planning to migrate from qmail pop3 to dovecot pop3 the number of users on the server is large over 5000 also data volume is large - over 3.5 tb -- ie many users several 1000s of emails in their inbox email clients used are outlook / outlook express / windows mail, etc my questions 1) will the migration cause all the emails on the server to re-download 2) can dovecot be configured to allow only one download at a time - pop3 locking with time out setting that can be customized 3) can dovecot pop3 be configured so that it will allow download of emails only of the last say 15 days ie even if the same pop3 user is configure on another machine it will download only messages of the last 15 days 4) has anybody migrated from qmail pop3 to dovecot pop3 successfully without emails being downloaded again thankyou very much in advance rajesh

[Dovecot] environment variables not set

[Dovecot] Upload / migrate old mails: iPhone shows oldest mails first
by Denny Schierz 19 Dec '12

19 Dec '12

hi, I've got a very strange behavior: I uploaded old mails from a local folder (thunderbird / osx) to my Dovecot (Debian Squeeze) and now, the iphone (ios6) show the oldest mails first. The only thing I can imagine is, that Dovecot got from Thunderbird the newest mails first and last the old mails, so that in the last mdbox are the old one. So, if it is correct, how can I fix it? cu denny

[Dovecot] Too many imap connections in state "idling"
by 3.listas＠adminlinux.com.br 19 Dec '12

19 Dec '12

Hi, I have a "Ubuntu12.04 + dovecot-2.0.19" configuration in my server. My mailbox server is shared by ~ 10k domains. It works fine with ~50k accounts. On average, my server has about 6K simultaneous imap connections during office hours. But I've noticed that this server has an average of approximately 4k connections in state "idling". On other Dovecot servers the average connections in state "idling" is only 10%. My doveconf -n: http://thiagoh.prv.digirati.com.br/doveconf-n.txt Can someone help me? Thanks -- Thiago Henrique adminlinux.com.br

[Dovecot] Dsync help, new attempt
by Torbjorn Astlind 19 Dec '12

19 Dec '12

I observe that dsync fills Maildir correctly incl. cur, if I delete Maildir just before dsync runs. Can the failed mbox to Maildir conversion be caused by dovecot creating Maildir automatically if a client connects to dovecot? Should dovecot be shutdown when running dsync? All the best, Torbjörn 9. dsync help?

Message-ID: <50C600B4.4040603(a)dbb.su.se> Content-Type: text/plain; charset=ISO-8859-1; format=flowed Hi all, I have dovecot serving aprox 200 users through mbox, but the time has come to migrate to a new server, and to use Maildir. Using rsync from the old server I get all user data, i.e /home/*, and inboxes i.e /var/mail/* to a new server. This has worked well for some time as backup. The dsync should convert everything to Maildir, and it does... to an extent. (linebrakes for easy viewing) What I see, is that often, the /home/mail/xxx is NOT resulting in /home/xxx/Maildir/cur All mailboxes from /home/xxx, are properly converted to /home/xxx/Maildir/.name_of_ box Am I misunderstanding something? I get it to work sometimes if I delete the ~/Maildir completely before doing the dsync.

[Dovecot] Advice on sieve vacation for aliases
by Marcio Merlone 19 Dec '12

19 Dec '12

Greetings, I have a working mail server with sieve 1:1.2.9-1ubuntu6.5 working just fine. My commercial dept. has asked me to set a vacation message for comercial(a)domain.tld, but this is an alias to jhon(a)domain.tld and meggie(a)domain.tld. I have created a sieve_global_path = /etc/dovecot/global.sieve and it works, but not the intended way: it sends two vacation messages, each From: each employee, and not From: comercial(a)domain.tld alias. Is there how to make dovecot send only one vacation message From: comercial(a)domain.tld or will I have to survive with one message from jhon and another from meggie? Also, is there how to have a dovecot.lda-dupes for the alias instead the users? /etc/dovecot/global.sieve: require ["vacation"]; # rule:[Ferias coletivas] if anyof (header :contains "To" "comercial(a)domain.tld") { vacation :days 7 :subject "Férias coletivas de 20/12/2012 a 07/01/2013" text: bla bla bla. ; stop; } Thanks in advance and nice holidays. -- Marcio Merlone

[Dovecot] Adding a parameter to dovecot's deliver to get a meaningful return value
by Cyril RUSSO 18 Dec '12

18 Dec '12

Hi, First, please forgive me as I'm not subscribed to the list. I'm using Dovecot 2 (2.1.7) for serving my local maildir. This maildir is filled by an external process, fetching & merging mails from different sources that's outside this scope (but it's working). Dovecot is thus acting as a MTA, but more as a MDA. I've a web client running on the server, and it connects to Dovecot to get the mails. I've configured this web client & dovecot to use sieve to filter the mails. I know that since Dovecot does not actually deliver the messages, it's not the expected behavior. Anyway, I can use the "deliver" software in your suite for passing sieve's rules on each message in my maildir, and it's almost working. I've a cron job that run deliver on each message of my maildir, but I'm a bit puzzled now. Basically, I'm not able to figure out if a message was matched by a sieve filter or not. I'm a bit disappointed by two things: 1) Sieve's reject doesn't make "deliver" to return an error, so a sieve rule chain ending in "reject" can't be detected from my cron's script. I wonder it's due to the step deliver is supposed to be run (after a mail is already accepted). 2) "deliver" doesn't have a method to find out if it processed the given mail as input. Basically, would it be possible to either add a parameter to "deliver" (for example: "--fail-on-discarding") so it would fail if the sieve rules discard or reject (/ereject) the mail ? That way, I could detect the failure in my script, and know that I don't need to delete the initial mail since it was not filtered. Or, thought differently, I wonder if "deliver" could open a socket/pipe/file whatever, and write the number of processed mails in there (or using a "--return-processed-mail"), so a sieve rule ending with "delete", would be detectable by my script. Best regards, -- Cyril

[Dovecot] Clear-text ldap passwords: {CLEAR} scheme?
by Kristof Bajnok 18 Dec '12

18 Dec '12

Hi, if I read the documentation correctly, the clear-text password storage scheme in Dovecot is called PLAIN. Unfortunately, in Sun LDAP Directory Server I have to specify them as "{CLEAR}" [1]. Is it somehow possible to make Dovecot recognise "{clear}foobar" passwords as plaintext? Now I get: auth: Error: ldap(username): Unknown scheme clear Thanks, Kristof [1]: http://docs.oracle.com/cd/E19850-01/816-6699-10/confattr.html#passwordStora…

[Dovecot] dovecot-lda (2.1.12) segfaults
by Joseph Tam 18 Dec '12

18 Dec '12

We uograded our dovecot from version 2.1.10 -> 2.10.12, but within the first hour of use, dovecot-lda would segfault during delivery. This left a lock file lying around causing the user's mail readers to hang; much hilarity ensues. All further deliveries to the same user will result in a crash. The only thing that fixes this condition is to blow away the user's INBOX cache index. Reindexing with "doveadm index" does not fix anything. I've installed a test version with one user's problematic INBOX cache indices and ran gdb dovecot-lda (gdb) run -t testuser </dev/null and it crashes with the following backtrace Program received signal SIGSEGV, Segmentation fault. 0xff2a0440 in mail_cache_header_fields_read (cache=0x5c120) at mail-cache-fields.c:323 323 if (field_hdr->size < sizeof(*field_hdr) + (gdb) bt #0 0xff2a0440 in mail_cache_header_fields_read (cache=0x5c120) at mail-cache-fields.c:323 #1 0xff29e8bc in mail_cache_compress_locked (cache=0x5c120, trans=0x63ce8, unlock=0xffbfeeef) at mail-cache-compress.c:361 #2 0xff29efd0 in mail_cache_compress (cache=0x5c120, trans=0x63ce8) at mail-cache-compress.c:489 #3 0xff2a3df4 in mail_cache_transaction_compress (ctx=0x5dac0) at mail-cache-transaction.c:180 #4 0xff2a4084 in mail_cache_transaction_open_if_needed (ctx=0x5dac0) at mail-cache-transaction.c:241 #5 0xff2a6e60 in mail_cache_field_want_add (ctx=0x5dac0, seq=1, field_idx=12) at mail-cache-transaction.c:1048 #6 0xff27e8e8 in index_mail_parse_header_register_all_wanted (mail=0x5e6b0) at index-mail-headers.c:175 #7 0xff27ec90 in index_mail_parse_header_init (mail=0x5e6b0, headers=0x0) at index-mail-headers.c:230 #8 0xff27f5c8 in index_mail_cache_parse_init (_mail=0x5e6b0, input=0x63760) at index-mail-headers.c:376 #9 0xff2299cc in mbox_save_get_input_stream (ctx=0x5dde8, input=0x62ed0) at mbox-save.c:411 #10 0xff22a084 in mbox_save_begin (_ctx=0x5dde8, input=0x62ed0) at mbox-save.c:520 #11 0xff24e9c0 in mailbox_save_begin (ctx=0xffbff514, input=0x62ed0) at mail-storage.c:1652 #12 0xff23f138 in mail_storage_try_copy (_ctx=0xffbff514, mail=0x54cd8) at mail-copy.c:68 #13 0xff23f23c in mail_storage_copy (ctx=0x5dde8, mail=0x54cd8) at mail-copy.c:93 #14 0xff24ec28 in mailbox_copy (_ctx=0xffbff670, mail=0x54cd8) at mail-storage.c:1721 #15 0xff24ec98 in mailbox_save_using_mail (ctx=0xffbff670, mail=0x54cd8) at mail-storage.c:1730 #16 0xff388070 in mail_deliver_save (ctx=0xffbff8a8, mailbox=0x13fe8 "INBOX", flags=0, keywords=0x0, storage_r=0xffbff83c) at mail-deliver.c:317 #17 0xff38869c in mail_deliver (ctx=0xffbff8a8, storage_r=0xffbff83c) at mail-deliver.c:403 #18 0x00012d08 in main (argc=3, argv=0xffbff964) at main.c:434 I dumped the value of field_hdr, and it has some bogus value (gdb) p field_hdr $1 = (const struct mail_cache_header_fields *) 0x20 Other observations - blowing away the indices does not fix it permanantly.

[Dovecot] NFS, deleting folder issue
by Catalin Petrescu 18 Dec '12

18 Dec '12

Hi there, I use dovecot on a server with some Nightmare File Systerm (aka NFS) storage. When I delete a folder, its content gets deleted, but the folder itself does not. Here's what I found: #### Step 1: From a shell, telnet to imap, then create a folder cpetrescu@cpetrescu-mobile:~$ telnet server1.localdomain 143 Trying 10.200.28.36... Connected to server1.localdomain.

Here's the content of F1 before calling delete_dir: Dec 05 10:29:14 imap(testuser1): my_delete_dir: d_name: "new" inode: 843617 Dec 05 10:29:14 imap(testuser1): my_delete_dir: d_name: "tmp" inode: 843623 Dec 05 10:29:14 imap(testuser1): my_delete_dir: d_name: "cur" inode: 843616 Dec 05 10:29:14 imap(testuser1): my_delete_dir: d_name: "dovecot.index.log" inode: 2363059 Dec 05 10:29:14 imap(testuser1): my_delete_dir: d_name: "." inode: 843612 Dec 05 10:29:14 imap(testuser1): my_delete_dir: d_name: ".." inode: 807717 And here's its content after calling delete_dir Dec 05 10:29:15 imap(testuser1): my_delete_dir: name: INBOX/F1 Dec 05 10:29:15 imap(testuser1): my_delete_dir: path: /data/testuser1/Maildir/INBOX/F1 Dec 05 10:29:15 imap(testuser1): my_delete_dir: ret: -1 Dec 05 10:29:15 imap(testuser1): my_delete_dir: error: "Directory not empty" trying again Dec 05 10:29:15 imap(testuser1): my_delete_dir: d_name: "." inode: 843612 Dec 05 10:29:15 imap(testuser1): my_delete_dir: d_name: ".." inode: 807717 Dec 05 10:29:15 imap(testuser1): my_delete_dir: d_name: ".nfs0000000000240eb3000000e0" inode: 2363059 Dec 05 10:29:15 imap(testuser1): my_delete_dir: ret: -1 So, the dovecot.index.log was deleted, but it's still open, and the folder can't be deleted because of the pesky .nfs* file. Now, the question: Is there a *magic* function that closes "dovecot.index.log" that I can call before delete_dir()? I tried mailbox_log_close() but it didn't help. Thanks a lot. p.s. Please don't suggest that I should not use NFS! I know that, and I don't really like NFS, but I have no other choice. Catalin Petrescu <catalin.petrescu gmail com>

[Dovecot] Manually creating dovecot- files after isync/mbsync mirror
by Dale Gallagher 18 Dec '12

18 Dec '12

Hi everyone I'm using isync 1.0.5 patched to do recursive folder listing and mirroring mail from an external party's IMAP server to a local Maildir, which will be accessed by Dovecot 2.0.9. In order to prevent IMAP clients from re-downloading their mail, when connecting to Dovecot, I'm busy writing a script to generate appropriate dovecot-uidlist and dovecot-uidvalidity files, per Maildir. isync stores the uid in the filename, so that's extractable, per message, and the uidvalidity and current max uid are stored in a file .uidvalidity, in each Maildir. I've read the docs here: http://wiki2.dovecot.org/MailboxFormat/Maildir Regarding the dovecot-uidlist header (first line) - I've tried to search for and figure out what exactly is meant by the "mailbox global uid" and once I do, how to manually generate the 128 bit hex variation of it? Could someone elaborate on this, please. How would omitting the global uid field, beginning with G, affect remote clients' syncing of mail? Is this field mandatory? I also see that Dovecot's uidvalidity is of the form 4df8a4e2, whereas isync uses an integer. I'd appreciate it if someone could elaborate on what Dovecot uses and whether I can convert one to the other? I'll post the full solution, once complete, and working. Thanks. Dale

Re: [Dovecot] Automatically Cleaning Kerberos Credential Cache Files

Ben Morrow writes: > In any case, it's likely that the delivery process looks in the user's > home directory even if delivery is to a separate mail spool, unless > you've taken steps to prevent this. I can confirm this. I think the reason is that dovecot changes to the user's home directory so that it has a place to dump core. This causes problem for my setup since I user per-user NFS mounts, so a delivery to an internal mailing list caused hundreds of NFS automounts. I patched this behaviour out, but there is probably a more elegant solution (unset MAIL_STORAGE_SERVICE_FLAG_ENABLE_CORE_DUMPS? How?).

[Dovecot] Removing configured SSL certificate file from disk while Dovecot is running spams syslog
by Nils 18 Dec '12

18 Dec '12

Hi! [root@mikan ~]# dovecot --version 2.1.12 When I remove the SSL certificate from disk while Dovecot is running, it spams syslog with the following log message over and over: Dec 6 17:41:41 mikan dovecot: config: Fatal: Error in configuration file /etc/dovecot/conf.d/10-ssl.conf line 12: ssl_cert: Can't open file /etc/ssl/private/dovecot.pem: No such file or directory Dec 6 17:41:41 mikan dovecot: config: Fatal: Error in configuration file /etc/dovecot/conf.d/10-ssl.conf line 12: ssl_cert: Can't open file /etc/ssl/private/dovecot.pem: No such file or directory Dec 6 17:41:41 mikan dovecot: config: Fatal: Error in configuration file /etc/dovecot/conf.d/10-ssl.conf line 12: ssl_cert: Can't open file /etc/ssl/private/dovecot.pem: No such file or directory [...] Reporting that the certificate went away is fine and useful, but spamming the syslog over and over with hundreds of entries per second(!) is annoying. :( I know what I'm doing, so reporting it once per connection attempt or something is enough. Even if Dovecot just decides to terminate, that would be fine. But a denial of service attack on syslog is not nice. Configuration output follows below. All the best, Nils [root@mikan ~]# dovecot -n # 2.1.12: /etc/dovecot/dovecot.conf # OS: Linux 3.5.4-1-ARCH x86_64 auth_failure_delay = 5 secs auth_mechanisms = plain login auth_verbose = yes listen = *,:: login_greeting = mail_location = maildir:~/.maildir namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { driver = pam } protocols = pop3 service pop3-login { inet_listener pop3 { port = 110 } inet_listener pop3s { port = 995 ssl = yes } } service pop3 { process_limit = 10 } ssl_cert = </etc/ssl/private/dovecot.pem ssl_key = </etc/ssl/private/dovecot.key userdb { driver = passwd } protocol imap { imap_idle_notify_interval = 2 mins mail_max_userip_connections = 5 } protocol pop3 { mail_max_userip_connections = 5 pop3_logout_format = pop3_save_uidl = no pop3_uidl_format = %08Xu%08Xv }

[Dovecot] Documentation of Redis and Memcache Backends
by Urban Loesch 18 Dec '12

18 Dec '12

Hi, in the release notes of 2.1.9 I read that dovecot supports memcache and redis backends for userdb/passdb authentication. This is very interesting for me and should reduce queries and database load of our mysql servers. My idea is to use memcache or redis in our IMAP/POP3 proxies in front of our backend servers. So I would like to try out if it's possible to store proxy information of our backends. For example the backend ip adress. But in the wiki I found only a few configuration settings for redis backend. http://master.wiki2.dovecot.org/AuthDatabase/Dict Also the mentioned example config file "dovecot-dict-auth.conf.ext" with full list of configuration options does not exits in the source of 2.1.11. Have you any idea where I can find the full info or any howtos? Many thanks and regards Urban

[Dovecot] Error: unlink_directory(.../lucene-indexes) with doveadm index
by Fred Kilbourn 18 Dec '12

18 Dec '12

Hi, Per discussion on this previous thread: http://dovecot.org/pipermail/dovecot/2012-October/068849.html I am updating search indexes on all my mailboxes via a nightly cronjob that runs: doveadm index -A '*' The problem we're running into is that random mailboxes will throw the following error during the update (sanitized to conceal actual domain name): doveadm(user(a)domain.com): Error: unlink_directory(/var/spool/mail/domain.com/user/sdbox/lucene-indexes) failed: Permission denied We have around 250 domains on the server, with a handful of mailboxes on average in each domain. We get this for a varying number of total mailboxes (1 to 6 every night). It is common for the same mailbox to show up a few days in a row and then stop throwing the error. The script is running as root, so there shouldn't be any file level permissions. Any thoughts on the root cause of these errors? What can I provide to help further diagnose? Thanks, Fred Kilbourn

[Dovecot] Dovecot version 1.2.17
by Philip Coackley 17 Dec '12

17 Dec '12

Hello, I am currently performing retrospective upgrades to an old ubuntu 9.10 Karmic Kola server. I need to upgrade dovecot 1.1.11 to 1.2.17 then to 2.0 etc. I have downloaded the binaries and run ./configure make make install. Dovecot compiles OK however I can not get the ./configure options to install at the following locations: executable: /usr/sbin/ config: /etc/dovecot/ Question: What are the ./configure options to do this? What are the ./configure options used to create the executable for unbuntu? (especially 9.10 if different). Reason for upgrade is auth-login errors every 2-3 weeks with 1.1.11 - looking at the release descriptions, this should fix this and the memory leaks! Phil Coackley

Hello Serveral of our clients are running into a problem relating to Gmails change in their "Check mail from other accounts (using POP3):". It seems related to the response dovecot sends back on a connection. Gmail is checking for a +OK in the header, however dovecot is sending OK without a prefix of +. Here is the response from Gmail webmail "Missing +OK response upon connecting to the server: * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE AUTH=PLAIN] Dovecot ready." Here is dovecot header on a pop3-ssl connection * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE AUTH=PLAIN AUTH=LOGIN] Dovecot ready. Who's end is this problem on? Google's, dovecots? Anyway to enable the response to include a +? Thanks Josh

I still run using mbox, and have not had a problem with corruption, however, this is probably owing to our modest IMAP demand and careful coordination of file locks among all the different MUAs. You're better off with Maildir and other formats, that are better designed for simultaneous access. There are other good reasons to switch formats. Dovecot also supports its own mdbox/sdbox for high performance: its a hybrid that tries to incorporate the best of both words. More info http://wiki2.dovecot.org/MailboxFormat > After those questions, it's just a "what do you think the pros and cons > of each are?" I can't speak to the other software you are looking at, but two factors I found to be particularly good: - flexibility: you can get almost every oddball setup to work. Migration from uw-imapd is fairly easy, but then again, uw-imapd didn't have a lot of knobs to turn. Plugins are available that extends its functionality. - support: this mailing list is great, and Timo is an absolute wizard in getting bugs fixed.

[Dovecot] more than one password_query
by goffer 15 Dec '12

15 Dec '12

Hello, I use dovecot + postfix with postfix sasl authentication by dovecot auth service. I have one question. Is it possible to have separate password_query only for auth service. I have two fields in database, one permits login to imap pop, second I want to use to permit login to smtp. Please explain how to set this (if it is possible) or give me some direction and sorry my English. -- View this message in context: http://dovecot.2317879.n4.nabble.com/more-than-one-password-query-tp39282.h… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] need help with dovecot-lda
by Andreas Meyer 15 Dec '12

15 Dec '12

Hello all! Some month ago I upgraded our dovecot installation from version 1.0.5 to version 2.1.7 without having any trouble. Postfix is delivering email directly per virtual transport to the maildirs and mailboxes of the users in /var/spool/vhosts/domains/.... Now I want to use dovecot-lda and created a new entry in the master.cf of postfix. dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/libexec/dovecot/dovecot-lda -f ${sender} -d ${recipient} It is not clear to me, how the dovecot-lda is started bei dovecot and you it finds the socket dovecot postfix created. The dovecot.conf looks like this; # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 2.6.22.5-31-bigsmp i686 openSUSE 10.3 (i586) ext3 auth_verbose = yes disable_plaintext_auth = no log_path = /var/log/dovecot1 mail_location = mbox:/var/spool/vhosts/%d/dovecotprivate/%n:INBOX=/var/spool/vhosts/%d/%n !include /etc/dovecot/conf.d/*.conf passdb { args = /etc/dovecot/passwd driver = passwd-file } userdb { args = /etc/dovecot/passwd driver = passwd-file } ssl_cert = < /etc/dovecot/ssl/hostcert.pem ssl_key = < /etc/dovecot/ssl/hostkey.pem #verbose_ssl = yes plugin { quota = maildir:User quota quota_rule = *:storage=500MB # 10% of 1GB = 100MB quota_rule2 = Trash:storage=+10%% # 20% of 1GB = 200MB # quota_rule3 = Spam:storage=+20%% autocreate = Trash autocreate2 = Drafts autocreate3 = Sent autosubscribe = Trash autosubscribe2 = Drafts autosubscribe3 = Sent } I set soft_bounce = yes in main.cf of postfix and delivery of mail fails with Dec 14 16:13:34 delta postfix/virtual[14082]: BBC0F1B31294: to=<xyz(a)anup.de>, relay=virtual, delay=395, delays=395/0.01/0/0.13, dsn=4.1.1, status=SOFTBOUNCE (unknown user: "xyz(a)anup.de") This is the relevant part of the main.cf: dovecot_destination_recipient_limit = 1 virtual_mailbox_domains = anup.de bit-corner.de bitcorner.de baubetreuung-meyer.de saxelektro.de virtual_mailbox_base = /var/spool/vhosts #virtual_mailbox_maps = hash:/etc/postfix/vmailbox #virtual_minimum_uid = 100 #virtual_uid_maps = static:5000 #virtual_gid_maps = static:5000 virtual_mailbox_limit = 524288000 virtual_transport = dovecot I don't get it right.

I am missing somthing but don't know what. Any help is appreciated! Andreas

[Dovecot] Dovecot "sleep" for short snapshots
by Peer Heinlein 15 Dec '12

15 Dec '12

Making consistent backups from Dovecot with mdbox requires a snapshoted filesystem with (at least) a short Downtime for Dovecot. I'd like to avoid killing several thenthousand IMAP-sessions for 60 seconds. Users don't like that... And the admin dislakes that too... What about a "short sleep" mechanism for Dovecot, where all writes are finished and new writes are easily delayed? I'd like to following process: *) "doveadm sleep" puts Dovecot in sleep-Mode: -- All existing writes are finished (before "doveadm sleep" is allowed to exit) -- All new writes are simply delayed -- All readonly-operations could work normally, so users can fetch and read mails *) The the admin can create a LVM-/SAN-snapshot of the filesystems *) "doveadm unsleep" will finish the magic Overall the whole process will take just some seconds. Users will recognize a simple write-delay, but they can work normally and the aren't unconnected at all. If the snapshot is really fast the users won't recognize the whole situation at all.

[Dovecot] More detail re dovecot-uidlist and -uidvalidity files
by Dale Gallagher 13 Dec '12

13 Dec '12

Regarding the dovecot-uidlist header (first line) - I've tried to search for and figure out what exactly is meant by the "mailbox global uid" and once I do, how to manually generate the 128 bit hex variation of it? Could someone elaborate on this, please. How would omitting the global uid field, beginning with G, affect remote clients' syncing of mail? Is this field mandatory? Would "3 V$uid_validity N$next_uid" be sufficient to ensure that clients don't re-download everything? I also see that Dovecot's dovecot-uidvalidity is of the form 4df8a4e2, whereas the IMAP syncing utility which I'm using (isync) uses an integer. I'd appreciate it if someone could elaborate on what Dovecot uses and whether I need to convert one to the other (ie. after syncing with isync, do I need to convert it to work with Dovecot? Thanks.

It's typical. Some popular mail readers open about 5, some more, some less. I set my mail_max_userip_connections at 12 even though there are some users who regularly bump up against this. They don't seem to notice -- dovecot probably bumps off the least recently used connection and their mail reader reconnects if it needs to open that mailbox again. Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] rare ssl issue

I'am having a rare situation with ssl connections. I can connect to 993/995 but the connection never starts. >From the client side i test with: $ openssl s_client -connect example.com:993 CONNECTED(00000003) and stays like that... waiting. In the other side i see in dovecot logs: Disconnected: Inactivity (no auth attempts): rip=x.x.x.x, lip=x.x.x.x, TLS handshaking this happens from some networks only, so i think that mi isp (where the server is hosted) is doing some kind of shaping. But if i try to connect to port 465 for example, or 443 it works like a charm. i am talking to my isp, but i thougth that someone may have a hint or any comment that could help. regards, eduardo.

[Dovecot] dovcot+offlineimap+gmail: INBOX empty, mail doubled
by Uwe Brauer 11 Dec '12

11 Dec '12

Hello I have used for years offlineimap-6.2.0 dovecot-imapd 1:1.2.9 in Kubuntu 10.04 Together with a imap server of my university. Yesterday we switched to google, which I know, is not a real imap server. I have 2 problems and the first I think has to do with either an old version of offlineimap or a bad configuration file: - All folders are downloaded+ Gmail[All Mail] so doubling my mail. - My INBOX folder is empty, however this is the only folder for which offlinemap gives the following warning: Syncing INBOX: Gmail -> MappedIMAP WARNING: UID validity problem for folder INBOX (repo UniLocal) (saved 1309334376; got 1355232397); skipping it So maybe this is also a offlineimap fault. In any case I have googled around and found out that I am not the only person suffering this problem. I have attached my configuration file in the hope that may be somebody could give me a hint.

Each user has one credential cache file in /tmp on the mail server after logging into Dovecot. We aren't using randomized names, so everything is in the standard format /tmp/krb5cc_uid. We do use KRB5 authenticated (and encrypted) NFS, but we don't deliver mail to home directories. Since all users are "real" users, and our office size is small, everyone has a mail spool directory on the mail server. Postfix is configured to use Dovecot for Kerberos. The relevant lines in its /etc/postfix/main.cf are as follows: smtpd_sasl_type = dovecot smtpd_sasl_path = private/auth smtpd_sasl_auth_enable = yes smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination smtpd_client_restrictions = permit_mynetworks, permit_sasl_authenticated, reject smtpd_sasl_security_options = noanonymous >> Currently, I have a cron job deleting the files manually every night. >> Obviously, this is a cruddy solution. > Well, I don't know about that: obviously, it would be a good idea to > work out what's going on here, in case it causes anything else to go > wrong, but a cronjob clearing out /tmp is a good idea in any case. Fair enough. And of course, I get a cache file every time I use sudo or log in through a GUI. Those aren't cleaned up either! Maybe I should be deleting credential cache files on all the machines every night. Those cache files have never given me a problem, though. >> I have Dovecot configured on a >> RHEL 6 box.

No random portion (the only application we have configured with random ccache names is SSH), just the usual /tmp/krb5cc_uid. Permissions appear correct, they belong to the appropriate user and group accounts. The SELinux permissions are set to: system_u:object_r:user_tmp_t:s0. This is different from the machine's credential cache (system_u:object_r:gssd_tmp_t:s0), but I've disabled and re-enabled SELinux during different parts of my testing and didn't notice any errors. Using GSSAPI directly doesn't create any cached credential files on the server. However, I just verified that I'm still sporadically getting the duplicate tickets (two lines for imap/hostname.server.com(a)SERVER.COM, with identical expiration dates). It comes and goes. I have a few users testing it for me, and they'll let me know if their logins break tomorrow like they have in the past once the normal log in period elapses. Since the "fix" for that problem is to log into the mail server, I have a hard time testing for the problem myself (being logged into the mail server nearly continuously just now). > What happens if you log in as an ordinary user (preferably using the > same PAM stack as Dovecot uses), use klist to find the ccache name and > 'ls -i' to find its inode number, then manually kinit again?

I've noticed that the ccache files for regular users do not get deleted when they log out. On another user's workstation, I found a ccache file for my account from a week ago (my current session was using a randomly generated SSH ccache file). I ran a command with sudo to force it to reauthenticate with pam_sss, and the timestamp on the ccache file was updated and the inode changed. My best guess is that pam_sss.so just doesn't do ccache cleanup. > Ben > Thanks for taking a look, I appreciate all the suggestions. This problem's been driving me up a wall for weeks now. I only just managed to narrow down the cause in the last few days. If I can't get a fix working in Dovecot, I'll try tackling it from a different perspective. I understand why Dovecot might not be cleaning up credential files (especially if it's just calling PAM normally), but I definitely do not understand why Postfix is behaving the way it does. If I can just get GSSAPI to work, I could probably bypass the problem as well. - Maura Dailey maura(a)eclipse.ncsc.mil

[Dovecot] Switch from MySQL/CourierMail to MySQL/Dovecot
by Robert Moskowitz 11 Dec '12

11 Dec '12

Hello, new here. I am a Centos/Fedora user, and for the past 3 years have been running my mail server using Postfix/MySQL/CourierMail/Squirrelmail on Fedora. The current incantation of the tutorial is at: http://www.howtoforge.com/virtual-users-and-domains-with-postfix-courier-my… Well it is time to rebuild my mailserver; this time on Centos 6.3. My goal is to use supplied rpms, not to build my own (and rebuild everytime there is an important update). So I am pulling quotas which has been a pain anyway, and I am investigating using Dovecot in place of CourierMail. In Centos 6.3, the version of Dovecot is: 2.0.9-2 I am looking for a tutorial to assist in the setup, as I am nowhere an expert on any of this (I am a communications security expert in the IETF and IEEE 802). There are a couple items that I have come to depend on in my current setup that are musts in anything new: Virtual user/domain That is, not only virtual domains, but also users defined by domain. So in the MySQL user table, the email value is set to user@domain. Thus a user can receive/send mail from multiple domains with the same addr and only those domains defined for the user in the user table. Obviously there is no coupling of Linux user accounts and email accounts. CourierMail is storing mail under /home/vmail/domain/user/... Encrypted passwords The passwords in the user table in MySQL are encrypted. This will be used to auth the user for POPing or IMAPing and sending their mail. I have encountered a few tutorials where it seems like passwords are stored in the clear? Anyway, not much else! Well as far as the user interface is concerned. Postfix with clamav and spamassassin and maybe one or two extras. And SquirrelMail for Webmail. A better gui than phpMyAdmin for maintaining the tables would be nice, but I don't have a lot of users, so it works well enough. Can someone point me to a tutorial best suited to my needs? Also any firewall rules, as I don't want to turn off iptables (and ip6tables) and any SELinux policy rules to add. Oh, and IPv6 will be a must in the near future, so anything needed to ensure IPv6 working right as well. Thanks

[Dovecot] Automatically Cleaning Kerberos Credential Cache Files
by Maura Dailey 10 Dec '12

10 Dec '12

I'm in a situation here at work where I'm trying to support a mixed network of OS X and RHEL desktop machines with a Postfix/Dovecot combination. - user account information is stored in LDAP - user credentials are in MIT Kerberos - server is running RHEL 6/Dovecot 2.0.9/Postfix 2.6.6 I am currently using the PAM passdb module to authenticate my users (I began to have trouble with using GSSAPI directly). After I implemented it, a few weeks later, I noticed that some users were no longer getting their mail if they hadn't logged in during the past day. Postfix's mailq showed that hundreds of messages were backing up in the queue. I eventually tracked it down to leftover Kerberos credential cache files (/tmp/krb5cc_????) sitting in /tmp on the mail server. The presence of expired credential files was preventing Postfix from delivering mail to those users' mail spools. If I delete the credential files manually, Postfix immediately delivers the queued emails. Currently, I have a cron job deleting the files manually every night. Obviously, this is a cruddy solution. I have Dovecot configured on a RHEL 6 box. The Pam stack on a RHEL 6 machine uses sssd (pam_sss.so) for authentication with Kerberos, not pam_krb5.so. I'm trying to track down which piece of the puzzle is responsible for cleaning up leftover credential caches. Is there a configuration option I can pass to Dovecot's passdb directly to clean up these cache files? Do others generally have more success using a custom PAM stack with pam_krb5.so instead of pam_sss.so? Poring over sssd's configuration options didn't reveal anything useful. I'm still not sure why Postfix even cares if there are expired credential cache files in /tmp at all. I'm back to trying GSSAPI directly again as well in the meantime on a few test clients. When I used that in the past, users were getting issued duplicate Kerberos tickets and users were forced to log into the mail server directly using SSH after a day in order to get their mail to work (seemingly a related issue). If I get those same errors again, I'll start another thread.

[Dovecot] dsync help?
by Torbjorn Astlind 10 Dec '12

10 Dec '12

Hi all, I have dovecot serving aprox 200 users through mbox, but the time has come to migrate to a new server, and to use Maildir. Using rsync from the old server I get all user data, i.e /home/*, and inboxes i.e /var/mail/* to a new server. This has worked well for some time as backup. The dsync should convert everything to Maildir, and it does... to an extent. (linebrakes for easy viewing) What I see, is that often, the /home/mail/xxx is NOT resulting in /home/xxx/Maildir/cur All mailboxes from /home/xxx, are properly converted to /home/xxx/Maildir/.name_of_ box Am I misunderstanding something? I get it to work sometimes if I delete the ~/Maildir completely before doing the dsync. All, and any help most welcome, Torbjörn for i in `cat /home2/torbjorn/SCRIPTS/userlist.txt`; do dsync -D -v -f -u $i -c /etc/dovecot/alt_config/10-mail.MBOX.conf backup maildir:~/Maildir; done > /home2/torbjorn/SCRIPTS/mb2mdRES.txt 2>&1 the -c 10.mail.MBOX.conf contains, the parts I think are relevant for the dsync operation: mail_location = mbox:~/home:INBOX=/home/mail/%u namespace { type = private separator = '/' inbox = yes } dsync(root): Debug: Effective uid=501, gid=501, home=/home/torbjorn dsync(root): Debug: Namespace : type=private, prefix=, sep=/, inbox=yes, hidden=no, list=yes, subscriptions=yes location=mbox:~/home:INBOX=/home/mail/torbjorn dsync(root): Debug: fs: root=/home/torbjorn/home, index=, control=, inbox=/home/mail/torbjorn, alt= dsync(root): Debug: Effective uid=501, gid=501, home=/home/torbjorn dsync(root): Debug: Namespace : type=private, prefix=, sep=/, inbox=yes, hidden=no, list=yes, subscriptions=yes location=maildir:~/Maildir dsync(root): Debug: maildir++: root=/home/torbjorn/Maildir, index=, control=, inbox=/home/torbjorn/Maildir, alt= dsync(root): Debug: Namespace : /home/torbjorn/Maildir doesn't exist yet, using default permissions dsync(root): Debug: Namespace : Using permissions from /home/torbjorn/Maildir: mode=0700 gid=-1 dsync(torbjorn): Debug: Namespace : Using permissions from /home/torbjorn/home: mode=0700 gid=-1

[Dovecot] IMAP instead of Maildir on Ubuntu Precise
by Thufir 10 Dec '12

10 Dec '12

Why is dovecot using Maildir and not IMAP. Or is it using even using Maildir at all? Currently I'm using mailman, postfix and dovecot to manage a mailing list. Mail is sent to thufir(a)dur.bounceme.net which the "mail server delivery agent stack provided by Ubuntu server team" of dovecot-postfix handles fine, keeping it locally, so far as it goes. The mail ends up in /home/thufir/Maildir, which the balsa mail client reads fine, as it handles Maildir fine. However, I would like to use dovecot-imapd which is installed. However, it's not clear quite how to switch over to IMAP. I see: root@dur:~# root@dur:~# nl /usr/share/dovecot/protocols.d/imapd.protocol 1 protocols = $protocols imap root@dur:~# root@dur:~# grep protocol /etc/dovecot/dovecot.conf # Enable installed protocols !include_try /usr/share/dovecot/protocols.d/*.protocol root@dur:~# which indicates to me that IMAP is configured. So, why is mail showing up using Maildir? I'm looking at: "Once you have chosen, amend the following line in the file /etc/dovecot/dovecot.conf: protocols = pop3 pop3s imap imaps" https://help.ubuntu.com/community/Dovecot Admittedly, I've not looked too closely into Dovecot man pages as I don't want to get too deep into the weeds on that if it's not even Dovecot I need to configure. I'm assuming that it's dovecot which is using Maildir: root@dur:/etc/postfix# root@dur:/etc/postfix# grep dovecot main.cf smtpd_sasl_type = dovecot smtpd_sasl_path = private/dovecot-auth mailbox_command = /usr/lib/dovecot/deliver -c /etc/dovecot/conf.d/01-mail-stack-delivery.conf -m "${EXTENSION}" root@dur:/etc/postfix# Can I force dovecot to only ever use IMAP and never use anything else? Is it maybe postfix which is using Maildir, and this is why my mail shows up as Maildir type mail? thanks, Thufir thufir@dur:~$ thufir@dur:~$ head .balsa/config -n 20 [mailbox-Inbox] Path=/var/mail/thufir Type=LibBalsaMailboxMbox Name=Inbox [mailbox-Outbox] Path=/home/thufir/Maildir/outbox Type=LibBalsaMailboxMbox Name=Outbox [mailbox-Sentbox] Path=/home/thufir/Maildir/sentbox Type=LibBalsaMailboxMbox Name=Sentbox [mailbox-Draftbox] Path=/home/thufir/Maildir/draftbox Type=LibBalsaMailboxMbox Name=Draftbox thufir@dur:~$

[Dovecot] Performance problems while running doveadm purge
by Jost Krieger 08 Dec '12

08 Dec '12

I have a rather large and active mdbox (28 GB, 3M mess, 1200 deliveries/day). I usually have no problems working with those mails, and there is some batch processing going on (via doveadm). Every few weeks I try my luck running doveadm purge, and this a) crunches about 5GB (to be expected), b) takes rather long (ok), c) leads to long stretches of blocked mdbox, which is the problem. I always turn off the batch processing, but deliveries take so long that they sometimes give up after timeout (they will come back later), and the IMAP clients get blocked for long minutes. Sometimes even the purge run aborts because of 3-minute-timeouts. What could be going on here (2.1.10)?

[Dovecot] Cannot STORE \Seen flag on some mails
by Frerich Raabe 07 Dec '12

07 Dec '12

Hi, I'm running Dovecot 1.2.17 on FreeBSD (exact output of 'dovecot -n' is atttached to this mail). The machine is serving a public mailinglist archive which is read-only; all mail arriving for the archive is marked as \Seen using Sieve script. This setup works well most of the time, but I noticed that for *some* mails, the \Seen flag doesn't seem to be stored. Right now I have 31255 mails in one of my folders and I can't seem to mark five of them as \Seen - the others work just fine. I first suspected a client issue so I did a little IMAP session by hand: * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE AUTH=PLAIN AUTH=LOGIN] Dovecot ready. . LOGIN "xxxxxx" "yyyyyy" . OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT IDLE CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS ACL RIGHTS=texk] Logged in . SELECT "Lists/Archive/squish" * FLAGS (\Answered \Flagged \Deleted \Seen \Draft $NotJunk) * OK [PERMANENTFLAGS ()] Read-only mailbox. * 31250 EXISTS * 0 RECENT * OK [UNSEEN 27126] First unseen. * OK [UIDVALIDITY 1350573750] UIDs valid * OK [UIDNEXT 31265] Predicted next UID * OK [HIGHESTMODSEQ 9512] Highest . OK [READ-ONLY] Select completed. . SEARCH UNSEEN * SEARCH 27126 27127 28484 29835 29838 . OK Search completed (0.000 secs). . STORE 27126 FLAGS \SEEN . OK Store completed. . SEARCH UNSEEN * SEARCH 27126 27127 28484 29835 29838 . OK Search completed (0.000 secs). . LOGOUT * BYE Logging out . OK Logout completed. Note how the first 'SEARCH UNSEEN' command shows that '27126' is unseen, the subsequent 'STORE' command succeeds - but then 'SEARCH UNSEEN' still shows 27126 as unseen! I have all four logging levels being piped to /var/log/maillog (I verified this by running dovecot --log-error) but the file does not show any problems. I checked the file permissions of the Maildir directories, and it all looks dandy to me. Does anybody have some suggestions how to debug this further, or what the reason for this may be? -- Frerich Raabe - raabe(a)froglogic.com www.froglogic.com - Multi-Platform GUI Testing

Sorry to ask such a basic question, but I finally got some major hurdles working for imaps on port 993 and Im getting the following when I try to connect from my iphone: imap-login: Disconnected (no auth attempts in 60 secs): user=<>, rip=192.168.1.1, lip=192.168.1.22, TLS handshaking: Disconnected Im using SQL and SSL over 993. I cant seem to find where my user comes from that its blank? Your help is appreciated. Thanks /mf/home/jeep/shell/.signature

[Dovecot] Message Flag definitions
by Chris Dutton 06 Dec '12

06 Dec '12

Hello, I am in charge of migrating our mail system from dovecot to another server, and I am having to write a script to do this as tools like imapsync are too slow. What I am trying to find is the definitions of the flags that dovecot adds to the Maildir file name it uses for the IMAP messages. For example what the a and b mean in the following: 1176236036.P7260Q1438.sucia:2,RSab I am looking for all definitions not just a and b. Thanks Chris chris(a)rosepointnav.com

[Dovecot] How can I force FTS reindexing?
by Dave Abrahams 06 Dec '12

06 Dec '12

I threw out my lucene-indexes folder because it seemed to be missing something, and I figured it would get regenerated. Unfortunately, dovecot is only FTS-indexing new mails that come in. Is there a way to get it to reindex everything? -- Dave Abrahams BoostPro Computing Software Development Training http://www.boostpro.com Clang/LLVM/EDG Compilers C++ Boost

I've got both 10.7 and 10.8 SDKs in Xcode and neither have SO_ISDEFUNCT defined in sys/socket.h (or anywhere else in the usr/include directories) -- there's a SS_DEFUNCT mask defined in sys/socketvar.h -- is that what you're looking for?

[Dovecot] Update configuration for separate mail directory
by eehmke 06 Dec '12

06 Dec '12

I have a small mail server with virtual users. In my /etc/dovecot/conf.d/10- mail.conf I have this setting: mail_location = maildir:/var/mail/vhosts/%d/%u which is also the home location of each user. Now I learned that this is not the prefered configuration, and in fact some of my sieve subdirectories are mistaken as mail directories. While I understand that I have to create separate mail subdirectories in each user folder, I am not sure where I have to adapt the dovecot configuration files. I could not find a guide, only some scattered hints and of course http://wiki2.dovecot.org/VirtualUsers/Home I guess I have to shut down the server for the reconfiguration, or is there a way to do it on a life system?

[Dovecot] When are search indexes updated?
by David Abrahams 06 Dec '12

06 Dec '12

I noticed that occasionally searching in my huge archive mailbox can be really slow, so I tried doveadm index on it and it seemed to do a lot of work, which seemed strange given, for example, that dovecot-lda says it keeps Dovecot index files up-to-date. Then I thought, "maybe these are different files than the search indices." If so, that's not entirely clear from the docs and Wiki. So, questions: * When are search indexes updated? * Are they updated incrementally? * If not, why not? * If so, why would a mailbox's index drift out-of-date, as mine had? BTW, I'm using the clucene search backend. -- Dave Abrahams BoostPro Computing Software Development Training http://www.boostpro.com Clang/LLVM/EDG Compilers C++ Boost

[Dovecot] dovecot backend on director ?
by Thomas Hummel 05 Dec '12

05 Dec '12

Hello Timo, The last time I checked my understanding about director was that : 1. backend/"real" imap servers should not be on the same host (or the same dovecot instance) to avoid proxying loops. Is it still the case with the latest 2.1 stable release ? Is there a plan to be able to run director and real server on the same host, thus requiring only 2 hosts instead of 4 to have load balancing and a redundant director ? 2. director itself was not able or meant to check if one of the real server was down (some script was pointed long time ago in this list). Same questions. 3. you'll have to use dovecot lmtp instead of let's say procmail. Would deliver be still a choice or is lmtp the only deliver compatible choice ? In what case would lmtp be more useful than deliver ? To have some sort of "remote LDA" ? By the way, what gets indexed on deposit on the mailbox since, by definition, the user has not done any request yet ?

[Dovecot] Quotas 2.1clarification
by Nick Edwards 05 Dec '12

05 Dec '12

Timo, I have much suspicion that our quota system is not working correctly since we migrate to 2.1 Currently using 2.1.10 Previously we had for issue of warnings quota_warning = storage=90%% /scripts/dqwarn-90.sh quota_warning2 = storage=75%% /scripts/dqwarn-75.sh worked great, these lines also migrated to new conf upon conversion. But quota conf example shows plugin { #quota_warning = storage=95%% quota-warning 95 %u #quota_warning2 = storage=80%% quota-warning 80 %u } # Example quota-warning service. The unix listener's permissions should be # set in a way that mail processes can connect to it. Below example assumes # that mail processes run as vmail user. If you use mode=0666, all system users # can generate quota warnings to anyone. #service quota-warning { # executable = script /usr/local/bin/quota-warning.sh # user = dovecot # unix_listener quota-warning { # user = vmail # } #} So this seems to indicate /scripts/dqwarn-75.sh should be a service name, which then calls the service quota-warning with that script in it etc etc etc surely this old 4 line method has not been replaced into a 20 line mess? Is this old way still functioning as I suspect it is not, and we need to write up two separate new quota warning services given our warnings are worded differently, or should the old methods still be working as they did in 1.2 and we have an error elsewhere?

Hello Timo, I've been using dovecot from many years now using Maildir mailbox format with default layout (Maildir++, everthing in a single directory). What would be the reason(s) to convert to Layout=fs ? I can only think of one : to allow dots in mailbox names. And even in that case, I guess I still have the option to use the litescape plugin. Besides, how would one process to do the conversion ? Using dsync ? Thanks. -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Groupe Exploitation et Infrastructure

This CVE isn't worthy of existence. A user can crash his/her own IMAP session by issuing a specific SEARCH command, which is just slightly worse than user issuing a LOGOUT command. It took years for people to notice this bug, because just about no IMAP client issues such a command.

[Dovecot] imap-login hanging when firewall blocks ssl handshaking
by Erik A Johnson 04 Dec '12

04 Dec '12

imap-login processes are hanging (using 100% of CPU) when connected from a client that is partially blocked by a firewall. It appears that imap-login is stuck in a loop trying to complete an ssl handshake. imap-login is working fine for other clients not blocked by the firewall (including localhost). This is dovecot 2.1.10 under Mac OS X 10.8.2 (compiled from sources); the firewall is Little Snitch 3.0.1 blocking port 993, which appears to let the connection initiate but then squashes and disconnects the socket during ssl handshaking. gdb backtrace and Activity Monitor's "Sample Process" show that imap-login is stuck calling ioloop-kqueue's io_loop_handler_run -> io_loop_call_io -> ssl_step repeatedly; dtruss shows that it is repeatedly making system calls to kevent and read, the latter returning -1 with errno 57=ENOTCONN="Socket is not connected". (I also tried ./configure --with-ioloop=poll and --with-iopoll=select instead of the default best = kqueue but the results were the same; --with-iopoll=epoll didn't work because epoll is not available on this machine.) The client, initiated by the command "openssl s_client -connect SERVER:993", first responds "CONNECTED(00000003)" but then immediately the error "60278:error:140790E5:SSL routines:SSL23_WRITE:ssl handshake failure:/SourceCache/OpenSSL098/OpenSSL098-44/src/ssl/s23_lib.c:182:". The infinite loop is in src/lib/ioloop.c in the function "io_loop_run" where the statement "while (ioloop->running) io_loop_handler_run(ioloop)" is executed. While I think the firewall is not doing the right thing (i.e., it lets a connection start but then kills it), it seems that imap-login should fail gracefully when the socket is no longer connected.

[Dovecot] clucene (in)stability

I'm going to try CLucene 0.9.21, which they claim has been "proven to be stable over time" (see http://clucene.sourceforge.net) and see how it works out. I wonder if there's a future envisioned for FTS with Dovecot that's suitable for small installations (i.e. doesn't require a Solr server) and has a good chance of correctness and stability? -- Dave Abrahams BoostPro Computing Software Development Training http://www.boostpro.com Clang/LLVM/EDG Compilers C++ Boost

[Dovecot] sieve problem after upgrade to 2.1.12
by Daniel Funke 03 Dec '12

03 Dec '12

Hi, I have a sieve filter for a mailbox with amavisd-admin mails. if header :regex "Subject" "^INVALID HEADER" { fileinto "INVALID HEADER"; } After the upgrade to dovecot 2.1.12 this filter doesn't work for some (16) messages with this subject. For 424 messages it worked correct. Any ideas where to look? Bye Daniel

[Dovecot] Thunderbird SSL/TLS client authentication fails
by Roger Hunen 03 Dec '12

03 Dec '12

Hi, This is my first post to the list, so greetings to you all! I am seeking your help with SSL/TLS client authentication. I currently have the following setup: * Server: - Debian Squeeze (fully patched) - OpenSSL 0.9.8o - Dovecot v2.1.10 (Debian backport package from Wheezy) - SSL listener on port 993 with the Dovecot selfsigned certificate that was created during installation - Virtual users (user(a)domain.net) with password in passwd style file * Client: - Windows XP SP3 (fully patched) - Thunderbird 17.0 - IMAP account using "Normal password" authentication - Roundcube webmail (to be added soon) This works just fine :) ==> I now want to set Thunderbird to use "TLS certificate" authentication so that I can safely expose port 993 to the internet for mobile use. The idea is that clients with a trusted client certificate do not need a password so that I can change my password for Roundcube without having to change passwords on other IMAP clients (Roundcube will connect to localhost without SSL). To do so I did the following: - use XCA (v0.9.3, Windows version) to setup a private root CA with a CRL - export root CA certificate and CRL in PEM format and join them into a ca.pem file (order: certificate, CRL) - configure Dovecot to use the ca.pem file and require a client certificate - use XCA to generate a private key and certificate for commonName=user(a)mydomain.net - import certificate and private key into Thunderbird - change IMAP account setting in Thunderbird to use "TLS Certificate" authentication - When prompted, select the imported certificate to be used for authentication. Unfortunately the authentication fails :( Using "verbose_ssl=yes" I can see in the Dovecot logfile that Thunderbird connects and that the SSL handshake completes successfully. "Valid certificate" is logged for both client certificate and root CA certificate. This looks "so far so good" to me :) The Dovecot log has the following lines at the point of failure: imap-login: Warning: SSL alert: where=0x4004, ret=256: warning close notify [<IP>] imap-login: Warning: SSL alert: where=0x4008, ret=256: warning close notify [<IP>] imap-login: Disconnected (no auth attempts in 0 secs): user=<>, rip=<IP>, lip=<IP>, TLS, session=<ID> (IP address and TLS session ID removed) The last log line ("user=<>") suggests that Dovecot does not try to use the commonName from the client certificate as the username even though (I think) I have configured Dovecot to do so. The relevant lines in the Dovecot configuration are: <config> auth_mechanisms = plain auth_ssl_require_client_cert = yes auth_ssl_username_from_cert = yes disable_plaintext_auth = yes protocols = imap ssl = yes ssl_ca = </etc/dovecot/ssl/ca.pem ssl_cert = </etc/ssl/certs/dovecot.pem ssl_cert_username_field = commonName ssl_key = </etc/ssl/private/dovecot.pem ssl_parameters_regenerate = 0 ssl_require_crl = yes ssl_verify_client_cert = yes service imap-login { chroot = login process_min_avail = 1 service_count = 1 inet_listener imap { port = 143 } inet_listener imaps { port = 993 ssl = yes } } </config> Observation: with "auth_ssl_require_client_cert = yes" Dovecot requires Thunderbird to send the client certificate even when Thunderbird uses "Normal password" authentication (authentication only fails if I delete the certificate from Thunderbird). So the SSL part looks OK to me. It seems that Dovecot is waiting for the client to logon over the established SSL/TLS connection instead of taking the username from the commonName in the certificate. ==> What could be going wrong here? I can post full config and logfile lines if you wnt to. Except for some possible oversight on my behalf there is nothing secret in there (I just didn't want to add too many lines to this already long post). Regards, -Roger

[Dovecot] Redelivery of mdbox messages to pass through sieve
by Hugh Davenport 30 Nov '12

30 Nov '12

Hey, I've been slack and haven't updated my sieve script for yonks, and finally got round to it. What I was wondering is whether there was a way to basically take all the messages from a folder and pass it through sieve again. I've found earlier messages in this list, but they were for Maildir format, not mdbox which I use now. Does anyone know of a way to do this? Cheers, Hugh

[Dovecot] Maildir conversion
by Aristidis Fesarlis 30 Nov '12

30 Nov '12

Hi all, I am using Dovecot 1.2.7, and trying to do my first Mbox to Maildir conversion. So I created a small script: > #!/bin/bash > > ls > userlist.txt > > for i in `cat userlist.txt`; do > echo "---------------------"; > echo "Converting user $i..."; > echo "---------------------"; > > su - $i -s /bin/bash -c "/opt/scripts/mb2md.pl -s mail -R"; > su - $i -s /bin/bash -c "/opt/scripts/mb2md.pl -m -s > /var/mail/$i"; > su - $i -s /bin/bash -c "cp ~$i/mail/.subscriptions > ~$i/Maildir/subscriptions"; > done > > rm -f userlist.txt I would like some help with the following: 1. Trying it, I get multiple warnings for some mailboxes like this: > "WARNING: UID from X-UID: header too low. Ignoring it Is this a problem? Or I can ignore it? 2. I understand that I also have to instruct my MDA (procmail) to deliver mail to the new location. I found that I have to create an /etc/procmailrc with the following line: > DEFAULT=$HOME/Maildir/ My question is: Some users have their own .procmailrc file inside their home directory, to filter mail etc. Their file does not contain the above statement. Would the default procmailrc file be processed for them as well? Or their file takes precedence, causing the default file not to be processed at all? Thank you

30 Nov '12

http://dovecot.org/releases/2.1/dovecot-2.1.12.tar.gz http://dovecot.org/releases/2.1/dovecot-2.1.12.tar.gz.sig The dovecot-config file installed by v2.1.11 was missing quotes, which broke building Pigeonhole. This release fixes that.

30 Nov '12

http://dovecot.org/releases/2.1/dovecot-2.1.11.tar.gz http://dovecot.org/releases/2.1/dovecot-2.1.11.tar.gz.sig * lmtp/lda: dovecot.index.cache file is no longer fully mapped to memory, allowing mail deliveries to work even if the file is huge. * auth: userdb passwd lookups are now done by auth worker processes instead of auth master process (as it was documented, but accidentally didn't work that way). + lmtp: lmtp_rcpt_check_quota=yes setting checks quota on RCPT TO. - lmtp: After successful proxying RCPT TO, the next one to a nonexistent user gave tempfail error instead of "user not found". - lmtp proxy: Fixed hanging if remote server was down. - imap: Fixed crash when SEARCH contained multiple KEYWORD parameters. - doveadm: Various fixes to handling doveadm-server connections. - -i <instance name> parameter for Dovecot tools didn't work correctly. - director was somewhat broken in v2.1.10. This version also includes various reliability enhancements. - auth: passdb imap was broken in v2.1.10.

Then, after no change - I remembered to do a "compact" in my MUA. That cleared up one mailbox - then dovecot complained about various errors & corruption on another mailbox. So I'll start a new thread for that as it looks like the solr interface is now good! -- Daniel

[Dovecot] mdbox corruption
by Daniel L. Miller 30 Nov '12

Trying to clean up the last of the corruption caused by my own stupidity. I now have two mailboxes for one user that give errors such as: doveadm(fax(a)amfes.com): Error: zlib.read(/var/mail/amfes.com/fax/mdbox/storage/m.9): gz trailer has wrong CRC value at 20065618 doveadm(fax(a)amfes.com): Error: read(/var/mail/amfes.com/fax/mdbox/storage/m.9) failed: Invalid argument (uid=238) doveadm(fax(a)amfes.com): Error: zlib.read(/var/mail/amfes.com/fax/mdbox/storage/m.9): corrupted data at 20145217 [...] doveadm(fax(a)amfes.com): Error: read(/var/mail/amfes.com/fax/mdbox/storage/m.20) failed: Invalid argument (uid=5155) doveadm(fax(a)amfes.com): Error: zlib.read(/var/mail/amfes.com/fax/mdbox/storage/m.20): corrupted data at 24779604 doveadm(fax(a)amfes.com): Error: Cached message size smaller than expected (1259 < 1260) doveadm(fax(a)amfes.com): Error: Corrupted index cache file /var/mail/amfes.com/fax/mdbox/mailboxes/INBOX/2010/dbox-Mails/dovecot.index.cache: Broken physical size for mail UID 5158 'doveadm force-resync' does not appear to fix these. There appear to be only the two mdbox files affected and I see about 40 errors. I would prefer to salvage as much as possible of these. What options do I have? Do a dsync to another location and take whatever I get? -- Daniel

[Dovecot] Missing Messages on IOS device
by David Morsberger 29 Nov '12

29 Nov '12

Resending because I didn't get any responses from my first post: I just converted my old server running UW/Panda to a Mac Mini Server running Mountain Lion (ML) Server. I'm using the postfix / dovecot setup provided by Apple. My IMAP clients are not showing all my emails. The Mail App on my iPhone and iPad is behaving the worse. I can see the emails that are not showing up in the cur directory. The ML Mail App is stating there are 3854 emails in my INBOX. There are 3948 files in the 'cur' directory ('ls cur | wc -l' returns 3948). Other mailboxes and directories have the same behavior. I'm not sure what to expect here. My method of conversion was to bulk copy (drag and drop) all the messages from one the UW server to the Dovecot server using the Apple Desktop Mail App in Mountain Lion. Any idea why these messages are not showing up on my devices and how I can get them to show up? bash-3.2# /Applications/Server.app/Contents/ServerRoot/usr/sbin/dovecotd --version 2.0.19apple1 bash-3.2# /Applications/Server.app/Contents/ServerRoot/usr/sbin/dovecotd -n # 2.0.19apple1: /Library/Server/Mail/Config/dovecot/dovecot.conf # OS: Darwin 12.2.1 x86_64 hfs aps_topic = com.apple.mail.XServer.fc3bb7c3-c8ef-4fe2-aff3-95ecd927fb11 auth_mechanisms = cram-md5 x-plain-submit plain login apop digest-md5 auth_socket_path = /var/run/dovecot/auth-userdb auth_username_format = %n default_internal_user = _dovecot default_login_user = _dovenull disable_plaintext_auth = no first_valid_gid = 6 first_valid_uid = 6 mail_access_groups = mail mail_location = maildir:/Library/Server/Mail/Data/mail/%u mail_log_prefix = "%s(pid %p user %u): " mail_plugins = quota zlib fts fts_sk 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 mdbox_rotate_size = 200 M passdb { args = /Library/Server/Mail/Config/dovecot/submit.passdb driver = passwd-file pass = yes submit = yes } passdb { driver = od } plugin { fts = sk quota = maildir:User quota quota_warning = storage=100%% quota-exceeded %u sieve = /Library/Server/Mail/Data/rules/%u/dovecot.sieve sieve_dir = /Library/Server/Mail/Data/rules/%u } postmaster_address = postmaster(a)mini.mmpcrofton.com protocols = imap pop3 lmtp sieve quota_full_tempfail = yes service auth { extra_groups = _keytabusers idle_kill = 15 mins unix_listener auth-userdb { user = _dovecot } } service dns_client { unix_listener dns-client { mode = 0600 } } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 ssl = yes } service_count = 0 } service imap { client_limit = 5 process_limit = 200 service_count = 0 } service lmtp { unix_listener lmtp { mode = 0600 } } service managesieve-login { inet_listener sieve { port = 4190 } } service pop3-login { inet_listener pop3 { port = 110 } inet_listener pop3s { port = 995 ssl = yes } } service pop3 { client_limit = 5 process_limit = 200 service_count = 0 } service quota-exceeded { executable = script /Applications/Server.app/Contents/ServerRoot/usr/libexec/dovecot/quota-exceeded.sh unix_listener quota-exceeded { group = mail mode = 0660 user = _dovecot } user = _dovecot } service quota-warning { executable = script /Applications/Server.app/Contents/ServerRoot/usr/libexec/dovecot/quota-warning.sh unix_listener quota-warning { group = mail mode = 0660 user = _dovecot } user = _dovecot } ssl_ca = </etc/certificates/*.chain.pem ssl_cert = </etc/certificates/*.cert.pem ssl_cipher_list = ALL:!LOW:!SSLv2:!EXP:!aNULL:!ADH:!eNULL ssl_key = </etc/certificates/*.key.pem ssl_key_path = /etc/certificates/*.key.pem syslog_facility = local6 userdb { args = partition=/Library/Server/Mail/Config/dovecot/partition_map.conf enforce_quotas=no driver = od } verbose_proctitle = yes protocol lmtp { mail_plugins = quota zlib fts fts_sk sieve push_notify } protocol lda { mail_plugins = quota zlib fts fts_sk sieve push_notify } protocol imap { imap_id_log = * imap_id_send = "name" * "version" * mail_max_userip_connections = 20 mail_plugins = quota zlib fts fts_sk imap_quota imap_zlib imap_fts urlauth } protocol pop3 { mail_max_userip_connections = 6 }

[Dovecot] Problem with mail_location and INDEX location
by Matt Jones 29 Nov '12

29 Nov '12

HI, I'm pulling my hair out a little trying to get dovecot to save it's index locally rather than in the NFS mount. No matter what I do it seems to save the indices in the Maildir on the NFS.

[Dovecot] Shutting down my Dovecot server?
by Bjørn T Johansen 29 Nov '12

29 Nov '12

I am planning to shut down my own Dovecot server and start using the other Dovecot server I am administering together with a friend.. And I was thinking that I don't want to copy the emails I have on my server so I want to start from scratch on the other server.. But I would like to be able to look at the old emails if I need to, so was wondering if there is a way to do this without using an imap server? Can I convert my mails stored in the maildir format to mbox or is there a better way to solve my problem?

[Dovecot] shared mailboxes and indexes
by Angel L. Mateo 28 Nov '12

28 Nov '12

Hello, We are deploying shared mailboxes in our mail system. We are running 2.1.9 and mail backend is maildir. As described at http://wiki.dovecot.org/SharedMailboxes/Shared when shared namespace is configured as namespace shared { separator = / prefix = shared/%%u/ location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u subscriptions = no list = children } each user accessing this folder has its own index, stored in ~/Maildir/shared/%%u/<shared mailbox>, hasn't it? Our mail is store in NFS disks so we are very concerned about indexes optimizations (we had performance problems until we got all of our indexes and nfs tunned). So, is there any way so those indexes could be shared for all users (and they always would be updated). Regarding this... if we'd use dbox instead of maildir, indexes are a really important part of the mailbox and they can't be re-constructed when they are outdated. So, how do shared mailboxes work with dbox backend? Do I have to configure indexes in any particular way? -- Angel L.

[Dovecot] problems with quota and clients
by Marco Sacchetto 28 Nov '12

28 Nov '12

Hi, I had configured dovecot in a pretty standard way and had it working nicely enough with maildir quotas (no tests done apart for reaching the quota and looking at mails coming back). Still I wanted to have the quota and the actual quota usage displayed in postfixadmin (3.5) but I think I messed with something. Now I can connect to the mailbox, send mail, receive mail, see the quota usage in postfixadmin but: * thunderbird: can create a subfolder if i do so by hand from the client. But if I try sending a mail i get a [TRYCREATE] mailbox error as it seems that thunderbird can't create the Sent box anymore by its own; * thunderbird: when i delete mail, it goes in the trash folder. I try then to delete it from there. In thunderbird indeed I see no mail anymore but the quota level remain the same. Then I try to browser the mail directory and... yep, all the messages are still there! How come? This is the output of dovecot -n and the relevant sql configuration : # 2.0.19: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-33-generic i686 Ubuntu 12.04.1 LTS ext4 auth_mechanisms = plain login auth_realms = yyyyyyyyy.it aaaaaaa.com xxxxx.it auth_verbose_passwords = plain debug_log_path = syslog dict { quotadict = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext sqlquota = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } first_valid_uid = 150 info_log_path = /var/log/syslog last_valid_uid = 150 listen = * mail_debug = yes mail_gid = mail mail_location = maildir:/var/vmail/%d/%u mail_plugins = " quota" mail_uid = vmail passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename mail_log_fields = uid box msgid size quota = dict:User quota::proxy::sqlquota quota_rule = *:storage=50M quota_rule2 = Trash:storage=+10M } postmaster_address = xxxxxxxx(a)yyyyyyyyy.it protocols = " imap pop3" service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } unix_listener auth-userdb { group = mail mode = 0600 user = vmail } } service dict { unix_listener dict { group = mail mode = 0660 user = vmail } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } protocol lda { mail_plugins = quota } protocol imap { mail_plugins = quota imap_quota } protocol pop3 { mail_plugins = quota } >>grep -v '^ *$#.*$\?$' dovecot-dict-sql.conf.ext connect = host=127.0.0.1 dbname=mail user=mail password=xxxxxxx map { pattern = priv/quota/storage table = quota2 username_field = username value_field = bytes } map { pattern = priv/quota/messages table = quota2 username_field = username value_field = messages } >>grep -v '^ *$#.*$\?$' dovecot-sql.conf.ext driver = mysql connect = host=localhost dbname=mail user=mail password=xxxxxxx default_pass_scheme = MD5-CRYPT password_query = \ SELECT username as user, password, '/var/vmail/%d/%u' as userdb_home, \ 'maildir:/var/vmail/%d/%u' as userdb_mail, 150 as userdb_uid, 8 as userdb_gid \ FROM mailbox WHERE username = '%u' AND active = '1' user_query = \ SELECT '/var/vmail/%d/%u' as home, 'maildir:/var/vmail/%d/%u' as mail, \ 150 AS uid, 8 AS gid, CONCAT('*:storage=',ROUND(mailbox.quota / 1024)) AS quota_rule \ FROM mailbox WHERE username = '%u' AND active = '1' iterate_query = SELECT username AS user FROM mailbox -- -- Questo messaggio è di carattere riservato ed è indirizzato esclusivamente al destinatario specificato.

[Dovecot] Any chance to access read-only mdboxes?
by Jost Krieger 28 Nov '12

28 Nov '12

We would like to provide a self-service restore function to our users using their IMAP client of choice.. Our idea was to use a snapshot (under ZFS, btrfs, whatever) and have it available to the user in a namespace. Unfortunately, but understandably, dovecot doesn't like the mdbox structure to be read-only. Is there any chance to change that? In the meantime, we could use a read-write snapshot, but we wouldn't like the users to really do changes to that snapshot. Our next attempt is to use ACLs, but it's a bit hard to gt the ACLs to the correct place in the snapshots, at least for thousands of users. Our currents solution (in test) is a quick and dirty patch to introduce inheritance to the ACLs by walking up the directory tree, so we need only one ACL. A cleaner solution would be very much appreciated. Yours Jost Krieger -- | Helft Spam ausrotten!

[Dovecot] Dovecot sieve with postfix.
by /#!/JoePea 28 Nov '12

28 Nov '12

Hi all, I can't get dovecot working with postfix. If I leave virtual_transport set to "virtual", I can send and receive messages just fine in roundcube. If I set virtual_transport to "dovecot", I can only send messages in roundcube, but incoming messages never arrive. Seems I can't get dovecot-lda to work. I need dovecot-lda in order for sieve filters to work. Any idea what I'm doing wrong? Here's `doveconf -n`: http://pastie.org/5401133 `postconf -n`: http://pastie.org/5401157 and `postconf -M`: http://pastie.org/5401177 Note: All I have to do is change virtual_transport = dovecot to virtual_transport = virtual and all will be fine, except for that I won't have sieve filtering which is what I really want. */#!/*JoePea

(BTW, I don't want to use port 143 at all.) # dovecot -n log_timestamp: %Y-%m-%d %H:%M:%S protocols: imaps listen: *:143,[::]:143 ssl_listen: *:993,[::]:993 ssl: required ssl_cert_file: /etc/dovecot/keycert.pem ssl_key_file: /etc/dovecot/keycert.pem ssl_cipher_list: TLSv1+HIGH:!SSLv2:!aNULL:!eNULL:!NULL:@STRENGTH login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login mail_privileged_group: mail mail_location: maildir:~/Maildir mbox_write_locks: fcntl dotlock auth default: passdb: driver: pam userdb: driver: passwd 1. Here is a snippet from dovecot.conf. Is it correct? Should I change something? (Note that I don't want to enable IMAP on port 143.) protocols = imaps protocol imap { listen = *:143,[::]:143 ssl_listen = *:993,[::]:993 } disable_plaintext_auth = yes ssl_listen = *:993,[::]:933 ssl = required ssl_cert_file = /etc/dovecot/keycert.pem ssl_key_file = /etc/dovecot/keycert.pem ssl_cipher_list = TLSv1+HIGH:!SSLv2:!aNULL:!eNULL:!NULL:@STRENGTH 2. I don't understand the syntax connected with auth. What auth options are enabled by default? dovecot.conf: No sections (e.g. namespace {}) or plugin settings are added by default, they're listed only as examples. Does it mean that passdb pam will use defaults (e.g. session=yes, setrcred=yes)? passdb pam { # [session=yes] [setcred=yes] [failure_show_msg=yes] [max_requests=<n>] # [cache_key=<key>] [<service name>] # # session=yes makes Dovecot open and immediately close PAM session. Some # PAM plugins need this to work, such as pam_mkhomedir. # # setcred=yes makes Dovecot establish PAM credentials if some PAM plugins # need that. They aren't ever deleted though, so this isn't enabled by # default. # # max_requests specifies how many PAM lookups to do in one process before # recreating the process. The default is 100, because many PAM plugins # leak memory. # # cache_key can be used to enable authentication caching for PAM # (auth_cache_size also needs to be set). It isn't enabled by default # because PAM modules can do all kinds of checks besides checking password, # such as checking IP address. Dovecot can't know about these checks # without some help. cache_key is simply a list of variables (see # /usr/share/doc/dovecot-common/wiki/Variables.txt) which must match # for the cached data to be used. # Here are some examples: # %u - Username must match. Probably sufficient for most uses. # %u%r - Username and remote IP address must match. # %u%s - Username and service (ie. IMAP, POP3) must match. # # The service name can contain variables, for example %Ls expands to # pop3 or imap. # # Some examples: # args = session=yes %Ls # args = cache_key=%u dovecot #args = dovecot } 3. Here is the output of `openssl s_client -tls1 -connect mail.example.com:993`. Is it OK?

[Dovecot] Default fallback behaviour
by Nikita Koshikov 27 Nov '12

27 Nov '12

Hello list, Here is the problem: I have few: passdb { #1 } passdb { #2 } And relative userdb sections. If user not found in 1) section it fallbacks to next one - it's expected and right, IMHO. But when the user exists in both section and password verification fails on 1) database it successfully authenticated on next one. I think this behaviour should be configured. The main goal of 1) section for this server is to overwrite users in main (section2) database. Maybe I missed something and this option is already in dovecot code and I can't find it ? Or if not - will it be added in the future ? Dovecot version 2.1.10.

[Dovecot] lmtp_rcpt_check_quota working somewhere?
by Steffen Kaiser 27 Nov '12

27 Nov '12

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, I'm running Dovecot v2.1 and enabled the lmtp_rcpt_check_quota option in conf.d/20-lmtp.conf, because I just found it in the sample config. Is this option working somewhere? When I have the option enabled, I get _no_ response in the RCPT TO phase, if the user is under quota. If I go on and enter the DATA keyword eventually, I get "554 5.5.1 No valid recipients", so it looks like, the user is really ignored at all. For an user over quota, I get: 552 5.2.2 <user> Quota exceeded (mailbox for user is full) Without lmtp_rcpt_check_quota LMTP works fine. For the user over quota I get the error after DATA phase, the user under quota gets the message delivered.

Many messages been continously delivered to this mailbox on this installation since May 2012, and the mdbox was only accessed with deliver and imap/pop3 from dovecot. About four hours after the problem initially appeared, I did a hard reset of the system because it was unresponsive. The error message is exactly the same before and after the hard reset. The problem is triggered by both IMAP access and dovecot deliver access. The whole mdbox is 6.6 GiB large and I guess that it contains about 300k-600k messages. It's an archive of public mailing lists, so I could give access to the files. Can anybody say something about this? May the mdbox be repaired?

[Dovecot] Dovecot IMAP/POP3 auto creating maildir
by Dominic Malolepszy 27 Nov '12

27 Nov '12

Hi I have observed that after deleting a mailbox and removing the user from the userdb, immediately accessing the mail account via POP3/IMAP causes Dovecot to auto create an empty mailbox, because the userdb/passdb details are still cached for 10minutes. Is there any option to tell Dovecot POP3/IMAP not to auto create the mailbox if it does not exist? Alternatively and less desirably is there a mechanism for telling Dovecot to expire a userdb/passdb cached entry? Running Dovecot 2.1.9 Dominic

[Dovecot] memory allocation issues

27 Nov '12

One of our dovecot backend servers ran into a problem with it's auth process a few days ago. This doesn't appear to be the error logged when dovecot hits its internal limit so I'm not sure what is going on here. auth: Error: malloc: 58012: Cannot allocate memory auth: Error: Unable to allocate memory for mutexes from the region auth: Error: PANIC: Cannot allocate memory auth: passwd(test,1.1.1.1,<8HTlNHzNIQBAjhKC>): unknown user pop3: Error: Authenticated user not found from userdb, auth lookup +id=2509111297 (client-pid=4781 client-id=1) pop3-login: Internal login failure (pid=4781 id=1) (internal failure, 1 +succesful auths): user=<test>... There was at least 10+GB free RAM on the server and no indication of a system level issue at the same time. The server is running 2.1.9. There were about 3,200 active sessions, with something like 12 new sessions/sec. The other identical servers are/were handling virtually identical load with the same service uptime and haven't had any issues so far.

[Dovecot] fs_flush_file_handle_cache_dir: rmdir(/var/mail) AGAIN
by Ken Mandelberg 27 Nov '12

27 Nov '12

We are running Dovecot 2.0.12. It runs on only one server and /var/mail is local where all the INBOX's are stored. Users other IMAP folders are NFS mounted on the server. We see frequent Error: nfs_flush_file_handle_cache_dir: rmdir(/var/mail) failed: Device busy I know this error message has been around a long time. Should we still be seeing it on 2.0.12 with a local /var/mail. Perhaps the message is misleading and really complaining about folders other than INBOX that are NFS mounted. Our config has dovecot.conf:mail_nfs_index = no dovecot.conf:mail_nfs_storage = yes is that correct given the above? Also, does the flush error messages have any real consequences? My understanding is that the rmdir is meant to fail, just to force a flush.

[Dovecot] Filesystem quotas
by Andreas Kasenides 27 Nov '12

27 Nov '12

I could not determine if when using filesystem quotas (http://wiki2.dovecot.org/Quota/FS) Dovecot will use the reported quota and limits without the need of configuring them via "quota_rules". Is this possible somehow? Such a feature would determine the quota limits automatically from the filesystem quotas thereby allowing to make use of them in quota warnings. Dovecot already knows the quota settings and limits. Here is evidence from the logs > Nov 21 19:24:22 iolaos dovecot: imap(user): Debug: box=/Mail/ank > mount=/newmail match=yes > Nov 21 19:24:22 iolaos dovecot: imap(user): Debug: quota-fs: > host=xxxx.xxxx.ucy.xx.cy, path=/mail, uid=211, bytes > Nov 21 19:24:22 iolaos dovecot: imap(user): Debug: quota-fs: uid=211, > value=2779115520, limit=8388608000 I am using (testing) version 2.2alpha1.

[Dovecot] Plugin help, number of messages in mailbox
by Richard Platel 27 Nov '12

27 Nov '12

Hi, We use Dovecot for IMAP and POP (but not LDA), we want to do something when a user has an INBOX that becomes empty, or becomes not empty (set a flag in memcached, but that's not really important). I'm writing a plugin (for Dovecot 2.1.7). On mailbox_open() I can use mailbox_get_status() to get a count of messages in the mailbox, and then decrement this in expunge() or increment it in mailbox save_finish() (for IMAP APPEND or COPY commands). However in expunge() and mailbox_save_finish, even after calling the super function, mailbox_get_status doesn't update the number of messages in the mailbox. This is a problem if (for example) there are concurrent POP sessions. Two POP sessions could get all the messages in INBOX, one could logout, calling expunge a few times, eventually causing my plugin to note that the inbox is empty, then our LDA could deliver a message, mark the INBOX not empty, then the other POP session could log out, call expunge and cause my plugin to mark the INBOX empty, when it's not. So in summation: how can a plugin be notified of changes to a mailbox, and then accurately get the real number of messages in that mailbox?

[Dovecot] Folder layout after Cyrus to Dovecot migration
by Keith Edmunds 27 Nov '12

27 Nov '12

# dovecot --version 1.2.15 We're trying to migrate a server from Cyrus to Dovecot, and we're mostly there. On Cyrus, the folder layout in the MUA is: INBOX subfolder subfolder ... Sent Drafts Queue Trash Users cannot create sibling folders to the Inbox, only subfolders (and sub-subfolders, etc). We've replicated that with: -------------------------------------------------------------------------------- mail_location = maildir:/shared/imapmail/users/%u:INBOX=/shared/imapmail/users/%u:LAYOUT=fs namespace private { separator = / prefix = "INBOX/" inbox = yes } -------------------------------------------------------------------------------- ...however, the Sent/Drafts/Queue/Trash folders are now subfolders of Inbox. Cyrus seems to default to the above layout (at least, I can't find anywhere that defines it). There are no special settings in the MUA to achieve the abovev. Is there a way of replicating the above within Dovecot? We can probably go to V2 if we have to, but 1.2.15 would be preferable. Thanks, Keith

[Dovecot] cannot update mailbox - unable to lock for exclusive access
by 1st WebDesigns 27 Nov '12

27 Nov '12

Hi there, We're using Dovecot version 1.0.7 and Postfix, and since upgrading our Linux box we're getting this in the maillog: Nov 8 07:49:11 server1 postfix/local[27901]: 04B8E7081DA: to=<xyz(a)xyz.com>, orig_to=<abc(a)abc.com>, relay=local, delay=19, delays=0.07/0/0/19, dsn=4.2.0, status=deferred (cannot update mailbox /var/spool/mail/abc for user abc. unable to lock for exclusive access: Resource temporarily unavailable) Postfix is currently set to: mailbox_delivery_lock = fcntl, dotlock Dovecot has this: mbox_read_locks = fcntl mbox_write_locks = fcntl dotlock I've scoured the web and tried all kinds of different locking mechanisms and combinations to no avail. The mail is eventually delivered but on a busy day this can take several hours. In the evening it generally doesn't happen, which leads me to believe it occurs during the day when people have their mail clients open. However, this particular issue doesn't affect every user that has their mail client open, only some! We currently have the mailboxes in mbox format - yes I know we should upgrade to maildir which we will eventually, however we've been using mbox for the last 10 years and this has only become an issue since upgrading. What I have discovered this morning is a Dovecot connection that is open for 6 minutes before disconnection. During this 6 minutes the above problem occurs (new mail cannot get an exclusive lock). The same user will have connected and disconnected several times before and after, with a connection taking no more than a few seconds. But it seems sometimes the connection is taking longer than it should and I suspect the problem lies here. Please can anyone help! Thank you, G

[Dovecot] IMAP proxy - can it detect parodying to itself?
by Graham Leggett 26 Nov '12

26 Nov '12

Hi all, I have some IMAP servers fronted with separate perdition processes, and it would be ideal if I could collapse this down to having dovecot do both the IMAP proxying and the IMAP serving at the same time on the same IP addresses. One of the fields in my LDAP entries contains the canonical name of the server that hosts their mailbox, and if I follow the manual at http://wiki2.dovecot.org/PasswordDatabase/ExtraFields#LDAP I could add the host field to enable proxying. My question is whether dovecot has the ability to notice whether dovecot is being asked to proxy to itself, in other words the value of "host" is the current dovecot server, and when this happens, ignore the proxy and just be a straight IMAP server, because the user has connected to the right box already. Is this possible? Regards, Graham --

Re: [Dovecot] doveadm fails with passdb authentication binds (dovecot 2.0.16)

Hello, >> # doveadm mailbox list -u user001 >> doveadm(user001): Error: user user001: Auth PASS lookup failed >> doveadm(user001): Fatal: passdb lookup failed > Are you running this on a Dovecot proxy? It looks like doveadm wants to do a passdb lookup to find out which server should handle this user. Passdb lookups don't work with LDAP binding. But if everything else works then I think you simply shouldn't have enabled doveadm proxying. So, set doveadm_proxy_port back to 0? thank you Timo, setting doveadm_proxy_port to 0 did the trick.

[Dovecot] Missing Messages on IOS device
by David Morsberger 26 Nov '12

26 Nov '12

I just converted my old server running UW/Panda to a Mac Mini Server running Mountain Lion (ML) Server. I'm using the postfix / dovecot setup provided by Apple. My IMAP clients are not showing all my emails. The Mail App on my iPhone and iPad is behaving the worse. I can see the emails that are not showing up in the cur directory. The ML Mail App is stating there are 3854 emails in my INBOX. There are 3948 files in the 'cur' directory ('ls cur | wc -l' returns 3948). Other mailboxes and directories have the same behavior. I'm not sure what to expect here. My method of conversion was to bulk copy (drag and drop) all the messages from one the UW server to the Dovecot server using the Apple Desktop Mail App in Mountain Lion. Any idea why these messages are not showing up on my devices and how I can get them to show up? bash-3.2# /Applications/Server.app/Contents/ServerRoot/usr/sbin/dovecotd --version 2.0.19apple1 bash-3.2# /Applications/Server.app/Contents/ServerRoot/usr/sbin/dovecotd -n # 2.0.19apple1: /Library/Server/Mail/Config/dovecot/dovecot.conf # OS: Darwin 12.2.1 x86_64 hfs aps_topic = com.apple.mail.XServer.fc3bb7c3-c8ef-4fe2-aff3-95ecd927fb11 auth_mechanisms = cram-md5 x-plain-submit plain login apop digest-md5 auth_socket_path = /var/run/dovecot/auth-userdb auth_username_format = %n default_internal_user = _dovecot default_login_user = _dovenull disable_plaintext_auth = no first_valid_gid = 6 first_valid_uid = 6 mail_access_groups = mail mail_location = maildir:/Library/Server/Mail/Data/mail/%u mail_log_prefix = "%s(pid %p user %u): " mail_plugins = quota zlib fts fts_sk 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 mdbox_rotate_size = 200 M passdb { args = /Library/Server/Mail/Config/dovecot/submit.passdb driver = passwd-file pass = yes submit = yes } passdb { driver = od } plugin { fts = sk quota = maildir:User quota quota_warning = storage=100%% quota-exceeded %u sieve = /Library/Server/Mail/Data/rules/%u/dovecot.sieve sieve_dir = /Library/Server/Mail/Data/rules/%u } postmaster_address = postmaster(a)mini.mmpcrofton.com protocols = imap pop3 lmtp sieve quota_full_tempfail = yes service auth { extra_groups = _keytabusers idle_kill = 15 mins unix_listener auth-userdb { user = _dovecot } } service dns_client { unix_listener dns-client { mode = 0600 } } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 ssl = yes } service_count = 0 } service imap { client_limit = 5 process_limit = 200 service_count = 0 } service lmtp { unix_listener lmtp { mode = 0600 } } service managesieve-login { inet_listener sieve { port = 4190 } } service pop3-login { inet_listener pop3 { port = 110 } inet_listener pop3s { port = 995 ssl = yes } } service pop3 { client_limit = 5 process_limit = 200 service_count = 0 } service quota-exceeded { executable = script /Applications/Server.app/Contents/ServerRoot/usr/libexec/dovecot/quota-exceeded.sh unix_listener quota-exceeded { group = mail mode = 0660 user = _dovecot } user = _dovecot } service quota-warning { executable = script /Applications/Server.app/Contents/ServerRoot/usr/libexec/dovecot/quota-warning.sh unix_listener quota-warning { group = mail mode = 0660 user = _dovecot } user = _dovecot } ssl_ca = </etc/certificates/*.chain.pem ssl_cert = </etc/certificates/*.cert.pem ssl_cipher_list = ALL:!LOW:!SSLv2:!EXP:!aNULL:!ADH:!eNULL ssl_key = </etc/certificates/*.key.pem ssl_key_path = /etc/certificates/*.key.pem syslog_facility = local6 userdb { args = partition=/Library/Server/Mail/Config/dovecot/partition_map.conf enforce_quotas=no driver = od } verbose_proctitle = yes protocol lmtp { mail_plugins = quota zlib fts fts_sk sieve push_notify } protocol lda { mail_plugins = quota zlib fts fts_sk sieve push_notify } protocol imap { imap_id_log = * imap_id_send = "name" * "version" * mail_max_userip_connections = 20 mail_plugins = quota zlib fts fts_sk imap_quota imap_zlib imap_fts urlauth } protocol pop3 { mail_max_userip_connections = 6 }

[Dovecot] sieve-extprograms strips Return-Path headers
by Ben Morrow 25 Nov '12

25 Nov '12

The sieve-extprograms extension strips Return-Path headers before passing mail off to the external program. The patch to remove this behavious is trivial (and attached), but since it appears to be deliberate I felt I should investigate further. I believe this is basically a cut-and-paste error. The code to strip Return-Path has been there since the sieve-pipe plugin for Dovecot 1.x, and I believe it was copied from the equivalent code in the 'redirect' action for passing mail off to sendmail(8). In that case, stripping Return-Path is correct, since the message is being resubmitted for delivery (by SMTP or otherwise), and the last step of the new delivery will (should) add a new Return-Path header with the new envelope information. In the case of sieve-extprograms, though, the filtering is happening post-delivery, so a stripped Return-Path will never be replaced. Ben

[Dovecot] Proxy to join two accounts
by Tomek 23 Nov '12

23 Nov '12

Hello, I have server with IMAP on dovecot for user mails and second server on archiveopteryx as mail archive. I'm wondering if it's possible to make some sort of proxy to these two servers in way where: - dovecot server will be main IMAP service with INBOX, etc - I want archiveopteryx account to be something like shared folder with read only access (no delete, no move, etc) in path ex. /archive/user.name - this proxy mappings should allow adding few archive accounts to one user (in case of people replacement) + it will be cool if this mappings could be defined in database so I could write tools to manage archive access for bosses. Is such case possible to achieve with dovecot (any howto or example would be very helpful)? If not - do you know any proxy tools that could allow such configuration? Thanks for any help. Regards, Tomek.

[Dovecot] v2.1.10: Director director_servers order issue
by Bertrand Jacquin 23 Nov '12

23 Nov '12

Hi, I'm setting up an IMAP/POP cluster using dovecot director for some NFS reasons and I'm getting some troubles with director_servers directive. Configuration is shared on both nodes : director_servers = 10.0.50.50 10.0.50.51 director_mail_servers = 192.168.0.150 192.168.0.151 director_user_expire = 15 min service director { unix_listener login/director { mode = 0666 } fifo_listener login/proxy-notify { mode = 0600 user = $default_login_user } unix_listener director-userdb { mode = 0600 } inet_listener { port = 9090 } } service ipc { unix_listener ipc { user = $default_login_user } } Here 10.0.50.50 is node1, 10.0.50.51 is node2 # ring status on node1 director ip port type last failed 10.0.50.50 9090 self never 10.0.50.51 9090 never # ring status on node2 director ip port type last failed 10.0.50.50 9090 self never 10.0.50.51 9090 never self is the same on both nodes, and that generate some cases that can be observed on logs : # logs on node1 dovecot: director: Error: Remote director thinks it's someone else (connected to 10.0.50.51:9090, remote says it's 10.0.50.50:9090) And this is true, TCP packet contain bad DATA : # tcpdump -i eth0 -nn src host 10.0.50.51 and port 9090 -s 0 -w - -l | strings | egrep '^ME' ME 10.0.50.50 9090 # logs on node2 dovecot: director: Error: connect(10.0.50.51:9090) failed: Invalid argument Invalid argument is present as bind() is not done with the appropriate IP : # strace -p 6063 -fF -s 1024 -e trace=bind,connect bind(28, {sa_family=AF_INET, sin_port=htons(0), sin_addr=inet_addr("10.0.50.50")}, 16) = 0 connect(28, {sa_family=AF_INET, sin_port=htons(9090), sin_addr=inet_addr("10.0.50.51")}, 16) = -1 EINVAL (Invalid argument) Also, during this time, CPU is ~100% used. bind() is done with node1 IP address. I also tested using a DNS : director_servers = director-all director-all is two A entries, first containing 10.0.50.50, second 10.0.50.51 and the result here is exactly the same. Using two configurations : # director_servers on node1 director_servers = 10.0.50.50 10.0.50.51 # director_servers on node2 director_servers = 10.0.50.51 10.0.50.50 Give the same result as showed before : # ring status on node1 director ip port type last failed 10.0.50.50 9090 self never 10.0.50.51 9090 never # ring status on node2 director ip port type last failed 10.0.50.50 9090 self never 10.0.50.51 9090 never It seems that first sorted entry in director_servers is considered as "self". I'm using dovecot 2.1.10-0~auto+55 debian package from rename-it repository. Thanks for your help. -- Beber

[Dovecot] whoson plugin for 2.0
by Chuck Cochems 23 Nov '12

23 Nov '12

I have found a plugin at ftp://ftp.ufanet.ru/pub/boco/dovecot/whoson-plugin/ I was able to make it function on a dovecot 1.2.8 server, by changing __attr_unused__ to ATTR_UNUSED and strlcpy to i_strocpy (since glibc doesn't HAVE strlcpy, on purpose). However, it doesn't work with 2.1 this is, of course, because getenv() no longer functions lie it used to in plugins. so i need a replacement for getenv("IP") and getenv("USER") to make this work. i know, pop before SMTP is stupid, but the isp i'm doing this for hs customers that have used pop before smtp for ages. so I MUST make a whoson plugin. as i said, the remote ip and the email address are required to interface with whoson. (this is superior to DRAC, which just opens the IP)

[Dovecot] User iteration with static userdb

Hi all, can someone explain me, please, why user iteration (iterate_query) doesn't work with static userdb? There isn't reason why it shouldn't work. In my opinion. However static userdb doesn't mean that user list not exist. Thanks Radek

[Dovecot] Is there a hook for a plugin to do some transient operation on the mail body ...
by Jay 23 Nov '12

23 Nov '12

... when the MUA has issued a FETCH? I am a Dovecot newbie ... so please bear with me if this is obvious. Basically what I am trying to do is process the mail body (in my own specific way) before Dovecot serves it up to the MUA. I want to do it as a transient operation in memory. So think of the scenario as ... - the MUA issues a FETCH - Dovecot intercepts the FETCH - Dovecot internally gets the mail from the storage into a buffer in memory ----> This is where I'd like to apply a function to the mail body and modify the mail body in the buffer (not in the storage) - Dovecot serves up the (modified) mail to the MUA Looking for a hook that allows me to do it using a plugin. Looks like the zlib plugin does something similar ... applies a decompression function ... but I am not 100% sure. Thanks for your help. -- J.

[Dovecot] maildir and end-of-line encoding
by Christoph Anton Mitterer 23 Nov '12

23 Nov '12

Hi. I just wondered, the following: My MDA may get mails that use LF or CR/LF end of line encodings and deliver them into maildirs. I couldn't find any information about, whether one should or must convert all into one format, cause AFAIK at least on the IMAP side, CR/LF is always used? How does this work on the maildir/backend side of dovcot? Can it work with both and simply automatically convert LF into CR/LF? Thanks, Chris.

Thank you. One thing that still doesn't work is subscribing to all mailboxes via "*", I guess because the folder names start with "." but dovecot mailbbox subscribe wants it without a starting "." Any clues how that can be solved? Regards Andre

[Dovecot] v2.1 memory usage
by Timo Sirainen 21 Nov '12

21 Nov '12

v2.1's imap/pop3 processes are linked with OpenSSL by default, because of imapc/pop3c storages. I wonder if you notice any actual (system-global) memory usage reduction when compiling without those and you have thousands of imap processes? ./configure --with-storages=mdbox sdbox maildir mbox cydir I guess I could try it myself also but maybe someone else wanting to reduce memory usage is quicker? :) Related to that, you can look at where imap processes' memory goes with: http://dovecot.org/tools/linux-maps-parse-imap.pl I don't know how much memory those (writable!) file-backed memory areas actually use per-process. Maybe nothing, maybe something..

[Dovecot] ACL and SSL

Finally got Dovecot to work on ports 100 and 143. I would like to a) Learn about ACL esp on port 110 as there are still yodellaks that try to brake in on port 110. b) Setting up separate SSL cert for imaps and pop3s. -- For effective Internet Etiquette and communications read http://catb.org/jargon/html/T/top-post.html, http://idallen.com/topposting.html & http://www.caliburn.nl/topposting.html -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

[Dovecot] users mail folders have to be subscribed
by Andre Bischof 19 Nov '12

19 Nov '12

Hi, I did a migration from cyrus 2.2 to dovecot (fresh installation, details below) via cyrus2dovecot from FU Berlin. That worked, but I first was missing mails in subfolders ander Inbox. No I detected that they are in the users Maildir in folders in his directory. They are listed when using telnet: * LIST (\HasChildren) "." "INBOX.ebay" * LIST (\HasNoChildren) "." "INBOX.ebay.xj" But they are not shown in thunderbird, I have to subscribe to them one by one. I probably did something wrong and maybe messed up with namespace and seperator settings - it would be great if one could lead me out of that. The wiki was a great help installing and configuring everything, but now I'm stuck. I use dovecot 2.1.7 under Ubuntu 12.10: # dovecot -n # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.5.0-18-generic x86_64 Ubuntu 12.10 auth_verbose = yes mail_debug = yes mail_location = maildir:~/Maildir managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation s ubaddress comparator-i;ascii-numeric relational regex imap4flags copy include variab les body enotify environment mailbox date ihave namespace inbox { inbox = yes list = yes location = prefix = separator = . type = private } passdb { driver = pam } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } postmaster_address = postmaster@localhost protocols = imap pop3 sieve service auth { unix_listener /var/spool/postfix/private/dovecot-auth { group = postfix mode = 0660 user = postfix } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_cipher_list = ALL:!LOW:!SSLv2:ALL:!aNULL:!ADH:!eNULL:!EXP:RC4+RSA:+HIGH:+MEDIUM ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } protocol imap { imap_client_workarounds = delay-newmail mail_max_userip_connections = 10 } protocol pop3 { mail_max_userip_connections = 10 pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_cipher_list = ALL:!LOW:!SSLv2:ALL:!aNULL:!ADH:!eNULL:!EXP:RC4+RSA:+HIGH:+MEDIUM ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } protocol imap { imap_client_workarounds = delay-newmail mail_max_userip_connections = 10 } protocol pop3 { mail_max_userip_connections = 10 pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } protocol lda { deliver_log_format = msgid=%m: %$ mail_plugins = sieve sieve postmaster_address = postmaster quota_full_tempfail = yes rejection_reason = Your message to <%t> was automatically rejected:%n%r } Any help is greatly appreciated!

[Dovecot] upgrade 1.0.15 -> 2.1.7: MBOX index compatibility and performance
by Benoit Branciard 19 Nov '12

19 Nov '12

Hi, we just upgraded our mailserver from Dovecot 1.0.15 to Dovecot 2.1.7. We use MBOX format (due to legacy compatibility), system users, PAM+GSSAPI auth, filesystem quotas, and indexes located on a separate filesystem: mail_location = mbox:~/mail:INBOX=~/mail/INBOX:INDEX=/var/cache/dovecot/indexes/%16Hu/%u The 2.1.7 configuration files have been rewritten based on default templates instead of converting it from 1.0.15. The server has ~8000 mailboxes and about ~2000 simultaneous IMAP/POP active connexions. The problem is: - indexes seem to be rebuilt: first IMAP/POP connexion for each user thows lots of error messages in the log, and the global index size decreases. Example error log: Nov 19 08:56:38 myhost dovecot: imap(myuser): Error: Cached message size larger than expected (27884 > 27855) Nov 19 08:56:38 myhost dovecot: imap(myuser): Error: Corrupted index cache file /var/cache/dovecot/indexes/4/myuser/.imap/INBOX/dovecot.index.cache: Broken physical size for mail UID 4414 Nov 19 08:56:38 myhost dovecot: imap(myuser): Error: Cached message size larger than expected (27884 > 27855) Nov 19 08:56:38 myhost dovecot: imap(myuser): Error: Corrupted index cache file /var/cache/dovecot/indexes/4/myuser/.imap/INBOX/dovecot.index.cache: Broken physical size for mail UID 4414 Nov 19 08:56:38 myhost dovecot: imap(myuser): Error: Cached message size larger than expected (27884 > 27855) Nov 19 08:56:38 myhost dovecot: imap(myuser): Error: Corrupted index cache file /var/cache/dovecot/indexes/4/myuser/.imap/INBOX/dovecot.index.cache: Broken physical size for mail UID 4414 Nov 19 08:56:38 myhost dovecot: imap(myuser): Error: Cached message size larger than expected (27884 > 27855) Nov 19 08:56:38 myhost dovecot: imap(myuser): Error: Corrupted index cache file /var/cache/dovecot/indexes/4/myuser/.imap/INBOX/dovecot.index.cache: Broken physical size for mail UID 4414 Nov 19 08:56:38 myhost dovecot: imap(myuser): Error: copy: i_stream_read() failed: Input/output error Nov 19 08:56:38 myhost dovecot: imap(myuser): Error: Cached message size larger than expected (27884 > 27855) Nov 19 08:56:38 myhost dovecot: imap(myuser): Error: Corrupted index cache file /var/cache/dovecot/indexes/4/myuser/.imap/INBOX/dovecot.index.cache: Broken physical size for mail UID 4414 - load average is extremely high (more than 10x the usual one), resulting from an significant increase of disk I/O, and for now (4h after the "monday rush") this doesn't seem to decrease. Questions: - are 1.05 indexes supposed to be backward compatible with Dovecot 2.1.7 ? - are there some technical reasons which could explain the increase of disk I/O, apart from index rebuild ? -- 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] advices for a new installation
by Surviet Amine 18 Nov '12

18 Nov '12

hello everyone, first of all, please forgive my bad english skill, I live in France. On our "old" Dovecot 1.x architecture, we have NFS shares between the front servers (MTA, IMAP...) and mail storage server. I've read some wiki2 pages that present the new director and imap proxy. But I'm still don't see things clearly, so I post here to have your advices to set-up a new mail architecture. The hardware we have : - 24x hard drives in a SAS bay - this bay is directly attached via SAS to a server that I'll call : mail storage server - 2 others servers run ProxMox Virtual Environment The PVE will help us to get many virtual servers : - MX : "mail in" servers - IMAP/POP : our hosted clients services These clients may come from webmail (RoundCube) and others clients (Outlook, Thunderbird, mobile clients...) - RoundCube webmail - MySQL server (hosts in databases accounts and settings for Postfix, Dovecot and RoundCube) - maybe antivirus and antispam servers I've read several threads about NFS and IMAP issues. So I decided to not keeping it. In this scenario, I've tried for the mail receiving part : - front-end (postfix lmtp-client) to mail storage server (lmtp server) that seems to runs fine, now i'll must try to add antispam and antivirus scans Now, for the IMAP part, could you, please tell me, if it is better to : - have several IMAP frontend servers that proxy to the mail storage server or - still keeps NFS between the mail storage server and the frontends Dovecot ? On our Dovecot 1.x webmail use imapproxy. I've read that others proxies exist. We have used for a limited time Perdition. What is the differences between imapproxy, Perdition, nginx imap proxy and Dovecot proxy ? Thanks for sharing your experience of "large mail service" that are solid enought to be scaled.

[Dovecot] Different Mechanism for POP3
by Tim Smith 18 Nov '12

18 Nov '12

Just wondered if there was a way of making the PLAIN an authentication method for POP3S transactions only without making this an option for IMAP? I am attempting to connect to a POP3S server through the GMail interface available through "Accounts and Import". The issue is that there does not seem to be an option to specify the type of mechanism within their interface so I think I have to offer PLAIN along with SSL. Has anyone else had any experience of using the GMail import settings? -- Tim Smith Tel: 01423 564 078 Mob: 07984 398 299 Email: info(a)titan21.co.uk Web: www.titan21.co.uk

[Dovecot] couple questions about dovecot
by Raan Young 17 Nov '12

17 Nov '12

I am attempting to migrate an ancient IMAP server to Dovecot 2.0.9 running on CentOS 6.3, while trying to minimize the impact on users. Most are using Outlook. I have everything working, but have run into a couple of problems, neither horrible, but both weird. It started when I noticed Outlook shows the .subscriptions file in the folder listing. I figured out a way to prevent that (see below), but then decided to attempt the same tactic to move the .imap index structure out of the folder tree and ran into an interesting side-effect. The .subscriptions issue would seem to be a bug, since the documentation I found implies Dovecot should be hiding it from list requests - as it does for the .imap index structure. I made a workaround by using the below mail_location setting. This puts the .subscriptions file above the imap folder structure and hence outside the list scope. mail_location = mbox:~/imap:INBOX=~/mbox:CONTROL=~:INDEX=~/.imap You'll note I have also moved the .imap index. This works, but the full path to the index files has extra layers of .imap. For example, if a folder tree of imap/A/B/C/D exists, where D is the actual mbox format message file, then the index files are stored in .imap/A/B/C/.imap/D. Don't know if this is a bug or I'm misunderstanding something. Can you provide any insight or better solutions for either issue? Some clients are also using iPhones and/or roundcubemail for web access. Those do not have the .subscriptions issue. Raan

[Dovecot] multiple users to same e-mail account with ldap authentication
by Marco Gatti 14 Nov '12

14 Nov '12

Hi, I was looking for a particular case of dovecot configuration I cannot find anywhere. Is there a way dovecot can authenticate via ldap different windows 2008 AD users that have access to the same e-mail account (like user authorization in ms exchange)? For example I want to extend AD schema to let users have 10 email accounts (with multiple domain support). If they are private accounts I think there is no problem at all. But if I want two or more users to access the same mail account what happens? Can I do it with dovecot? Or should I create AD groups and add members to that, to let user access the same mail account? Cheers -- Marco

[Dovecot] Dovecot 2.1.10

14 Nov '12

Hi all, I've a problem with dovecot-2.1.10. At time we use dovecot-1.2 without zlib. We setup a new server with dovecot 2.1.10. After syncing the emails everything looks fine. But if we use zlib plugin all new emails have no content. There are a lot of "Error: Maildir filename has wrong S value" log entrys. So we have compiled dovecot-2.0.18 and we use exactly the same configuration. Everything works. What can be our problem with version 2.1.10? Greets Ralf

[Dovecot] dovecot lost mail! Cause?

14 Nov '12

Hi, After using dovecot for several years now, today happend something which makes me really feel unconfortable: An email received was just not delivered properly, or, is lost! The mail (from an external server) was sent to two local mailboxes, user1 and user2. user1 received the message but for user2, it *magically* disappeared. MTA is exim4 which definitely processed the messages and handed over to dovecot deliver: 2012-11-12 07:28:21 1TXnVG-00053I-GD SA: [...] id=8644593.887351352701 685934.JavaMail 2012-11-12 07:28:21 1TXnVG-00053I-GD => user1 <user1(a)example.com> R=dovecot T=dovecot_pipe 2012-11-12 07:28:21 1TXnVG-00053I-GD => user2 <user2(a)example.com> R=dovecot T=dovecot_pipe 2012-11-12 07:28:21 1TXnVG-00053I-GD Completed Also, the log of dovecot tells that the mail should have been stored: Nov 12 07:28:21 mail dovecot: deliver(user1): sieve: msgid=<8644593.887351352701685934.JavaMail>: stored mail into mailbox 'INBOX' Nov 12 07:28:21 mail dovecot: deliver(user2): sieve: msgid=<8644593.887351352701685934.JavaMail.orbitz>: stored mail into mailbox 'INBOX' user1 received the mail but user2 not. Since user2 is myself, I *know* that I did not accidently delete any mail or something like that. It was just never received! Disk space is 3GB left, so enough. So I grepped the whole Maildir of user2 for the message ID. There is only one match in the dovecot.index.cache and within that, the most important data of the mail (Message ID, Date, Sender, Receiver, Subject) appears. But apart from that, not a single file! Is there hope to ever find out why what was going wrong here? It feels me veeeeeeeeery unconfortable because from now on I can never be sure any more that all my mails are really received :( :( However, as I said, my mail system processed maybe millions of messages the past 8 years. Although, I can not be sure if that was the case ... :( And help greatly appreciated! Luke PS: Dovecot version 1.2.15 (Debian 6.0.6) with Maildir backend on local harddrive. No NFS, nothing which can go wrong ... PPS: Original log files, just named replaced for privacy.

[Dovecot] Dovecot newbie (migrating from qmail)
by Ajai Khattri 13 Nov '12

13 Nov '12

Ive been using qmail+vpopmail+courier-imap for many years but its time to retire that server so I thought this might be an opportunity to see how I could use Postfix and Dovecot to provide the same services. Im running Dovecot 2.1.9 and Postfix 2.9.4. I have spent a few days reading through some of the docs on the wiki (there's doesn't seem to be any large overview of Dovecot concepts or books so bear with me). Im thinking something simple like passwd-file setup would suffice for me. I want to use completely virtual users. Id like to store mail under /home/vmail/$domain/$user. I think Ive figured out how to do that. But how do I create the maildir? I understand the need to have a mail directory but also a directory for things like sieve - how to specify that? Im thinking the structure would be something like: /home/vmail/$domain/$user/mail <-- mail stored here /home/vmail/$domain/$user/ <-- sieve and other sundry store here Or should the sieve stuff also be under its own folder alongside the maildir? Is it possible to have a separate passwd file per domain? It is possible to combine password and userdb files into one per domain? (I prefer to keep all files related to each domain in its own folder). Also would like to configure Postfix to use dovecot-sasl and I want to use dovecot-lmtp for deliveries. Any good docs / example on those? Later on, I think I want to integrate some kind of virus and spam filtering (amavisd and maybe dspam - anybody used those? would I configure Postfix to handle that or dovecot-lmtp?) Im sure Ill have more questions as I get more complicated but baby steps for now. -- Aj.

[Dovecot] Commercial features in Dovecot future: Object storage, archive
by Timo Sirainen 13 Nov '12

13 Nov '12

Hi all, Dovecot Oy’s web pages at www.dovecot.fi have been updated. The products page lists two features that will be available for commercial licensing, extending the functionality of the basic open-source version of Dovecot. * Storing emails to (high-latency) object storage, initially supporting Amazon S3, Caringo CAStor and Scality. * Email archive storage. See http://www.dovecot.fi/products/index.html for details. I’ve been developing Dovecot for over 10 years now. For a long time it was my primary motivation in life to create the best IMAP server available :) I think I've pretty much accomplished that by now. The future is looking very bright for Dovecot: we will continue the open source development stronger than ever, but in addition, for the long term it needs some additional licensed components that bring the money to cover the cost for future Dovecot development and to be able to build up the support in a professional way. These new features will be added as plugins on top of Dovecot to extend the functionality. Note that I’m not just randomly choosing which features will be open and which will be licensed. Only some specific features will be licensed where my company is going to make money with partnerships and in other measurable ways.

[Dovecot] mbox vs. maildir storage block waste
by Christoph Anton Mitterer 12 Nov '12

12 Nov '12

Hi. I recently mentioned in several posts, that I'd tended to use mbox rather than maildir, because you don't loose so much space (due to always allocating full blocks per maildir file and thus per mail). I made some tests of my archive, which consists of some 3,4 million mails at a total of 42GB). Most of these mails are probably normal sized, but there are also some with bigger attachments. For those who are interested here are the results: I used a 53687091200 B image file (via loop device) and tested ext4 only. btrfs is IMHO not yet ready, I have had often issues with XFS (corruptions), reiser4 is more or less dead and reiser3 is said to have issues (see e.g. its wikipedia article, even though it has that mode for small files which would fit nicely). As you see the number of mails increased a bit, cause I tested over several days... but this is only a very small increase so it shouldn't change the numbers a lot. 1) Original mbox archives (right now in Evolution) mbox exact space: 38122676224 (does not include meta-data) mbox guess space: 44625670144 (includes Evolution meta-data which is several GBs) mbox num mails: 3412999 (occurances of From_ lines) In the following: - image file, 1B-blocks, Used_begin, Used_end, Available_begin, Available_end result out of df -B 1 - mdir exact used space is the sum of du -B 1 for each regular file (i.e. each mdir file) - mdir guess used space du -B 1 on the root dir of the filesystem - mdir num mails: find . type -f | wc -l on the root dir of the filesystem 2) EXT4 with 4096 blocks: image file: 53687091200 1B-blocks: 52844687360 Used_begin: 188555264 Used_end: 45198778368 Available_begin: 49971777536 Available_end: 2444972032 mdir exact used space: 44810866688 mdir guess used space: 45010243584 mdir num mails: 3423296 delta: 6.688190464 G delta / mail: 1953 B 3) EXT4 with 2048 blocks: image file: 53687091200 1B-blocks: 50324295680 Used_begin: 82857984 Used_end: 41598846976 Available_begin: 47557083136 Available_end: 6041094144 mdir exact used space: 41323991040 mdir guess used space: 41516007424 mdir num mails: 3425033 delta: 3.201314816 G delta / mail: 934 B 4) EXT4 with 1024 blocks: image file: 53687091200 1B-blocks: 50314834944 Used_begin: 38287360 Used_end: 39909360640 Available_begin: 47592193024 Available_end: 7721119744 mdir exact used space: 39683908608 mdir guess used space: 39871086592 mdir num mails: 3425033 delta: 1.561232384 G delta / mail: 455 B As you can see, the delta per mail is rather close to the statistically expected values of 2048B, 1024B and 512B. In the end I probably changed my opinion. ~7GB of wasted block space for all my mails is actually quite a lot, but in days of cheap disk space it's acceptable. And with mbox one has IMHO the major disadvantage that mailservers (including dovecot) store some meta-data _in_ it (i.e. in the mails themselves) , which I don't like a lot. I still think about reports that mbox is much faster with full text search (which sounds reasonable)... but therefore one needs probably and database backend anyway. HTH, Chris.

[Dovecot] Invalid Managesieve commands are counted twice
by Christoph Bußenius 12 Nov '12

12 Nov '12

Hi, the Managesieve server closes the connection if it receives an unknown command before authentication: "IMPLEMENTATION" "Dovecot Pigeonhole" "SIEVE" "fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave" "NOTIFY" "mailto" "SASL" "PLAIN" "STARTTLS" "VERSION" "1.0" OK "Dovecot ready." --> BOGUS NO "Error in MANAGESIEVE command received by server." NO "Error in MANAGESIEVE command received by server." BYE "Too many invalid MANAGESIEVE commands." Connection closed by foreign host. Note that only one bogus command has been sent by the client, however the server sends two identical error messages. This seems to be a bug in Pigeonhole 0.3.3. In version 0.2.6, the connection was kept open after the error message. This is actually important to us because we use the "sieveshell" utility which is shipped with the Python "managesieve" package. The managesieve.py module always sends a BOGUS command after the TLS handshake. According to its comments, this is done to work around problems with other server implementations: # Some servers send capabilities after TLS handshake, some # do not. We send a bogus command, and expect a NO. If you # get something else instead, read the extra NO to clear # the buffer. typ, data = self._command('BOGUS') (The full source is at http://pydoc.net/managesieve/0.4.2/managesieve) As a result, sieveshell cannot be used with TLS and a current Dovecot/Pigeonhole server.

[Dovecot] Solr 4.0 - lucene - FTS
by Charles Marcus 12 Nov '12

12 Nov '12

Hi Timo, As one who is interested in implementing FTS sometime in the future, I'm curious about what is in store as far as improvements go... Specifically, any plans for implementing immediate/automatic index updates at delivery time? The lack of automatically updated indexes is one downside for its implementation... Also, does the release of Solr 4.0 mean anything for the lucene library used by dovecot? http://www.marketwatch.com/story/lucidworks-congratulates-apache-foundation… Thanks, -- Best regards, Charles

[Dovecot] Sieve puts incoming message into inbox on any problem with submission_host
by Christian Rohmann 11 Nov '12

11 Nov '12

Hello dovecot-users, I have a question/suggestion regarding the submission_host feature of the lda (either via dovecot-lda binary or lmtp) in combination with sieve. When trying to deliver message to a mailbox and this message has a sieve redirect action applied to it, dovecot is using the configured smtp server to forward the message just fine. Unfortunately, if the server configured for submission is unavailable, returns an error or cannot be found via DNS, sieve will simply put the message into the inbox and be done with it: --- dovecot.log --- dovecot: lda(user1): Error: lmtp client: DNS lookup of idonotexist.example.com failed: Name or service not known dovecot: lda(user1): Error: sieve: msgid=unspecified: failed to redirect message to <user2> (refer to server log for more information) dovecot: lda(user1): sieve: msgid=unspecified: stored mail into mailbox 'INBOX' dovecot: lda(user1): Error: sieve: execution of script /mailboxes/user1/.dovecot.sieve failed, but implicit keep was successful (user logfile /mailboxes/user1/.dovecot.sieve.log may reveal additional details) --- /dovecot.log --- The same applies to vacation messages being sent out. Especially with an (unconditional) redirect action, users don't expect to find messages in their inbox. Also problems with the submission_host could very much be temporary and a little delay in delivering a message is better then putting it somewhere the user doesn't expect a message to be. Is there any way to change the behavior of dovecot or the sieve plugin to tempfail in case a message cannot be sent out? I know that with multiple sieve actions it gets more complicated as there could be corner cases were the first message can be sent via the submission server and another message produced by the same sieve script cannot. I'd love sieve to behave like this: a) if submission host is unreachable (hostname wrong, timeout, ...) -> tempfail b) if submission host returns 4xx error -> tempfail c) if submission host returns 5xx error -> fail(-save) and just drop the message into inbox or even have an option to reject the message completely in this case. In case of a tempfail response, the mta simply queues the message and tries again later. In case of a permanent fail the mta will create a bounce message to in form the sender. Regards and have a great weekend, Christian

We have 1 proxy with director and 2 mail servers. we use LDAP when I try to do doveadm quota get -u user it works fine. The problem is when I try to do doveadm quota get -A ON PROXY I have this result: doveadm(first_user): Error: Proxy is missing destination host doveadm: Error: Failed to iterate through some users Username Quota name Type Value Limit % in 10-auth.conf I have "!include auth-ldap.conf.ext" in auth-ldap.conf.ext I hve: passdb { driver = ldap args = /etc/dovecot/dovecot-ldap.conf.ext } userdb { driver = ldap args = /etc/dovecot/dovecot-ldap.conf.ext } and In dovecot-ldap.conf.ext I have: uris = ldap://ldap:port dn = xxxxx dnpass = yyyyy auth_bind = no ldap_version = 3 base =base scope = subtree user_attrs = attributes user_filter = (mail=%u) pass_attrs = userPassword=password,uid=user=%L$,cn=proxy,=starttls=any-cert pass_filter = (mail=%u) iterate_attrs = uid=user iterate_filter = (uid=*) I don't know where is my error!!!

[Dovecot] quota recalc does not work
by Adrian Stoica 09 Nov '12

09 Nov '12

Hi I upgraded dovecot from 2.0 to 2.1 , and now i face the quota recalc problem. All settings are keep in mysql Before , after a change in mailbox.quota field, i run doveadm quota recalc and all was ok , but now that command doesn't do anything. After i change a quota for a user , i have to restart dovecot to get the new quota , or do a "doveadm reload" instead of recalc. And the doveadm quota recalc -A" give me back a lot of "doveadm(username): Info: User no longer exists, skipping" Any thoughts ? # 2.1.10: /usr/dovecot21/etc/dovecot/dovecot.conf # OS: Linux 2.6.35.4 i686 auth_cache_negative_ttl = 1 secs auth_cache_size = 2 M auth_failure_delay = 4 secs auth_mechanisms = plain login digest-md5 cram-md5 auth_worker_max_count = 100 base_dir = /var/run/dovecot/ default_client_limit = 4096 default_internal_user = vmail default_login_user = nobody default_process_limit = 256 deliver_log_format = mail delivery from=%f subject=%s msgid=%m: %$ dict { acl = mysql:/usr/dovecot21/etc/dovecot/dovecot-dict-sql.conf.ext } disable_plaintext_auth = no first_valid_uid = 1 lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes listen = * mail_location = maildir:~/Maildir mail_plugins = " quota acl trash notify mail_log" 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 namespace { hidden = no list = children location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u prefix = shared/%%u/ separator = / subscriptions = no type = shared } namespace inbox { inbox = yes list = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = separator = / subscriptions = yes type = private } passdb { args = /usr/dovecot21/etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { acl = vfile acl_shared_dict = proxy::acl autocreate = Trash autocreate2 = Drafts autocreate3 = Sent autosubscribe = Trash autosubscribe2 = Drafts autosubscribe3 = INBOX autosubscribe4 = Sent mail_log_events = delete mailbox_delete mailbox_rename mail_log_fields = box subject from msgid size quota = maildir:User quota quota_warning = storage=95%% quota-warning 95 %u quota_warning2 = storage=95%% quota-warning 90 %u quota_warning3 = storage=85%% quota-warning 85 %u sieve = ~/.dovecot.sieve sieve_dir = ~/sieve trash = /usr/dovecot21/etc/dovecot/dovecot-trash.conf.ext } postmaster_address = postmaster(a)dacris.net protocols = imap quota_full_tempfail = yes rejection_subject = Rejected: %s: %r service auth { unix_listener auth-client { mode = 0666 user = vmail } unix_listener auth-userdb { mode = 0666 user = vmail } } service dict { unix_listener dict { user = vmail } } service imap-login { process_min_avail = 4 } service imap-postlogin { executable = script-login /bin/imap.sh unix_listener imap-postlogin { mode = 01232 } } service imap { executable = imap imap-postlogin process_limit = 1024 vsz_limit = 1 G } service quota-warning { executable = script /bin/quota_warning.sh unix_listener quota-warning { user = vmail } user = vmail } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = /usr/dovecot21/etc/dovecot/dovecot-sql.conf.ext driver = sql } protocol lda { mail_plugins = " quota acl trash notify mail_log sieve autocreate" } protocol imap { imap_client_workarounds = delay-newmail mail_max_userip_connections = 20 mail_plugins = " quota acl trash notify mail_log imap_quota imap_acl" } dovecot-sql.conf.ext: password_query = SELECT password FROM mailbox WHERE \ username = '%Ln' AND domain = '%Ld' AND \ active = '1' user_query = SELECT CONCAT('/srv/vmail/',mailbox.domain,'/%Ln') AS 'home' ,'98' AS 'uid', '98' AS 'gid' , \ CONCAT('*:storage=', mailbox.quota,'M') AS quota_rule ,"Trash:storage=+50M" AS quota_rule2 FROM mailbox WHERE \ mailbox.username = '%Ln' AND mailbox.domain = '%Ld' AND \ mailbox.active = '1' iterate_query = SELECT username AS user , domain FROM mailbox WHERE active = '1'

[Dovecot] Mails don't get deleted after POP3
by cullinan＠rocketmail.com 09 Nov '12

09 Nov '12

Hi, there! Well, I am new to dovecot, so please be patient with me: I have a virtual server and want to setup simple mail delivery. postfix, saslauthd and dovecot basically work fine. The only open issue is, that (I guess) dovecot doesn't remove the mail when it's retrieved via pop3 from the server. It keeps sending me the same emails again and again. (The mail client (Thunderbird) is configured to remove the messages from the server - it was working already.) I guess that dovecot cannot write to some files / has problems with write permissions. But it doesn't tell me anything... Can you tell me, what configuration might be wrong or how can I enable more debugging to see what dovecot is doing after the mails got sent out via pop3? Here is the configuration: # dovecot -n # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.38-8-server x86_64 Ubuntu 11.04 log_timestamp: %Y-%m-%d %H:%M:%S protocols: pop3 pop3s login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/pop3-login mail_privileged_group: mail mbox_write_locks: fcntl dotlock mail_executable: /usr/lib/dovecot/pop3 mail_plugin_dir: /usr/lib/dovecot/modules/pop3 auth default: passdb: driver: pam userdb: driver: passwd -----8<----- # dovecot -a # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.38-8-server x86_64 Ubuntu 11.04 base_dir: /var/run/dovecot log_path: info_log_path: log_timestamp: %Y-%m-%d %H:%M:%S syslog_facility: mail protocols: pop3 pop3s listen: * ssl_listen: ssl: yes ssl_ca_file: ssl_cert_file: /etc/ssl/certs/dovecot.pem ssl_key_file: /etc/ssl/private/dovecot.pem ssl_key_password: ssl_parameters_regenerate: 168 ssl_cipher_list: ssl_cert_username_field: commonName ssl_verify_client_cert: no disable_plaintext_auth: yes verbose_ssl: no shutdown_clients: yes nfs_check: yes version_ignore: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/pop3-login login_user: dovecot login_greeting: Dovecot ready. login_log_format_elements: user=<%u> method=%m rip=%r lip=%l %c login_log_format: %$: %s login_process_per_connection: yes login_chroot: yes login_trusted_networks: login_process_size: 64 login_processes_count: 3 login_max_processes_count: 128 login_max_connections: 256 valid_chroot_dirs: mail_chroot: max_mail_processes: 512 mail_max_userip_connections: 10 verbose_proctitle: no first_valid_uid: 500 last_valid_uid: 0 first_valid_gid: 1 last_valid_gid: 0 mail_access_groups: mail_privileged_group: mail mail_uid: mail_gid: mail_location: mail_cache_fields: mail_never_cache_fields: imap.envelope mail_cache_min_mail_count: 0 mailbox_idle_check_interval: 30 mail_debug: no mail_full_filesystem_access: no mail_max_keyword_length: 50 mail_save_crlf: no mmap_disable: no dotlock_use_excl: yes fsync_disable: no mail_nfs_storage: no mail_nfs_index: no mailbox_list_index_disable: yes lock_method: fcntl maildir_stat_dirs: no maildir_copy_with_hardlinks: yes maildir_copy_preserve_filename: no maildir_very_dirty_syncs: no mbox_read_locks: fcntl mbox_write_locks: fcntl dotlock mbox_lock_timeout: 300 mbox_dotlock_change_timeout: 120 mbox_min_index_size: 0 mbox_dirty_syncs: yes mbox_very_dirty_syncs: no mbox_lazy_writes: yes dbox_rotate_size: 2048 dbox_rotate_min_size: 16 dbox_rotate_days: 1 mail_drop_priv_before_exec: no mail_executable: /usr/lib/dovecot/pop3 mail_process_size: 256 mail_plugins: mail_plugin_dir: /usr/lib/dovecot/modules/pop3 mail_log_prefix: %Us(%u): mail_log_max_lines_per_sec: 10 imap_max_line_length: 65536 imap_capability: imap_client_workarounds: imap_logout_format: bytes=%i/%o imap_id_send: imap_id_log: imap_idle_notify_interval: 120 pop3_no_flag_updates: no pop3_enable_last: no pop3_reuse_xuidl: no pop3_save_uidl: no pop3_lock_session: no pop3_uidl_format: %08Xu%08Xv pop3_client_workarounds: pop3_logout_format: top=%t/%p, retr=%r/%b, del=%d/%m, size=%s dict_db_config: dict_process_count: 1 managesieve_max_line_length: 65536 managesieve_logout_format: bytes=%i/%o managesieve_implementation_string: dovecot auth default: mechanisms: plain realms: default_realm: cache_size: 0 cache_ttl: 3600 cache_negative_ttl: 3600 executable: /usr/lib/dovecot/dovecot-auth user: root chroot: username_chars: abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@ username_translation: username_format: master_user_separator: anonymous_username: anonymous krb5_keytab: gssapi_hostname: winbind_helper_path: /usr/bin/ntlm_auth failure_delay: 2 verbose: no debug: no debug_passwords: no ssl_require_client_cert: no ssl_username_from_cert: no use_winbind: no count: 1 worker_max_count: 30 process_size: 256 passdb: driver: pam args: deny: no pass: no master: no userdb: driver: passwd args: -----8<----- Please let me know if you need more.

[Dovecot] Dovecot ok for port 110, but not for SSL (beginner asking)
by ycc_Swe 09 Nov '12

Hello, I just installed Dovecot. It works for plaintext autorization, port 110. It has connected with Telnet, Thunderbird and an on-line pop3 client. Telnet: +OK Dovecot ready. user nnnnn -ERR Unknown command. user nnnnn +OK pass xxxxxxxxxx +OK Logged in. stat +OK 1 1553 retr 1 +OK 1553 octets Return-path: <sssssss(a)hotmail.com> Envelope-to: nnnnnn(a)mydomain.com Delivery-date: Tue, 06 Nov 2012 12:02:28 +0100 Received: from bay0-xcvxcv-xvxcv.bay333.hotmail.com ([123.123.123.123]) by deb7.pc with esmtp (Exim 4.80) But when I try ssl (port 995) with an on-line pop3 client, it will not work: /var/log/mail.log Nov 7 02:46:55 deb7 dovecot: pop3-login: Disconnected (no auth attempts in 0 secs): user=<>, rip=12.12.12.7, lip=123.123.123.123, TLS: Disconnected, session=<Iza75N3NlABBNykH> Nov 7 02:46:56 deb7 dovecot: pop3-login: Disconnected (no auth attempts in 1 secs): user=<>, rip=12.12.12.7, lip=123.123.123.123, TLS: Disconnected, session=<nWTF5N3NlQBBNykH> root@deb7:~# doveconf -n # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-3-686-pae i686 disable_plaintext_auth = no mail_gid = mail mail_location = mbox:~/mail:INBOX=/var/mail/%u namespace inbox { inbox = yes location = prefix = } passdb { args = username_format=%u /etc/dovecot/users driver = passwd-file } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = " imap pop3" ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = username_format=%u /etc/dovecot/users driver = passwd-file } I know very little about mail and ssl.

As you can see I am a beginner with Dovecot, I hope it is still OK to ask on this mailing list.

The current stable release is RHEL 6.3, released in June 2012. What is the valid reason preventing you from upgrading to the 6.x distribution? The packages in general in 6.x are 5 years newer than 5.x. And given the fact that RHEL runs miles behind the bleeding edge, you're way behind the curve even with a recent RHEL distribution. You can probably find a much newer version of Dovecot in an RPM somewhere, and Postfix for that matter. But it would be better for you if you simply upgraded to RHEL 6.3. -- Stan

[Dovecot] IP/SSL configuration

Is there a way I can have something like the following setup: 192.168.0.2 port 110/143, with no starttls/ssl 192.168.0.3 port 110,995/143,993 with starttls/ssl 192.168.0.4 port 110,995/143,993 with starttls/ssl I am looking to setup dovecot so that some IPs will run without any notion of SSL whereas other IPs will run with with ssl/starttls available, each with its own certs

[Dovecot] pop3 exim4 dovecot
by Patrick Shirkey 08 Nov '12

08 Nov '12

Hi, I have an exim4 and dovecot system. The system has multiple accounts. Exim4 is receiving emails in the /var/mail/user files and dovecot is configured to use /home/user/mail (mbox) folder. I have one account that dovecot is not processing replies/bounces/etc... The data is being written in the /var/mail/user file by exim4 but as far as dovecot is aware there is nothing in the pop3 inbox. Can anyone suggest how I can enable dovecot to know that the data is in the /var/mail/user file and deliver it to the pop3 inbox for this account? -- Patrick Shirkey Boost Hardware Ltd

[Dovecot] v2.2.alpha1 released
by Timo Sirainen 08 Nov '12

08 Nov '12

http://dovecot.org/releases/2.2/alpha/dovecot-2.2.alpha1.tar.gz http://dovecot.org/releases/2.2/alpha/dovecot-2.2.alpha1.tar.gz.sig I wanted to start stabilizing v2.2 release some months ago already, but I somehow got stuck adding more and more features. Now it looks like all of the necessary API changes are done, so everything I'm planning on near future can still be added to v2.2 without major changes. The redesigned dsync hasn't had much testing yet, so avoid running it with important mails. Would be nice if people started testing and reporting any bugs. I was going to create some kind of a test suite for testing all the possible syncing combinations and also doing some random stress testing, but I haven't had time for that yet. The new dsync supports doing very fast syncs by saving the resulting state and giving it as command line parameter to the next sync. So for example doveadm sync -s "" > new-state saves the state and doveadm sync -s `cat new-state` continues from the saved state. The replicator code doesn't yet support this. * When creating home directories, the permissions are copied from the parent directory if it has setgid-bit set. For full details, see http://wiki2.dovecot.org/SharedMailboxes/Permissions * "doveadm auth" command was renamed to "doveadm auth test" * IMAP: ID command now advertises server name as Dovecot by default. It was already trivial to guess this from command replies. + Implemented IMAP MOVE and BINARY extensions + Implemented IMAP CATENATE, URLAUTH and URLAUTH=BINARY extensions (by Stephan Bosch). + Implemented IMAP NOTIFY extension. Requires mailbox_list_index=yes to be enabled. + Redesigned and rewritten dsync. The new design makes the syncing faster, more reliable and more featureful. The new dsync protocol isn't backwards compatible with old dsync versions (but is designed to be forwards compatible with future versions). + All mailbox formats now support per-user message flags for shared mailboxes by using a private index. It can be enabled by adding :INDEXPVT=<path> to mail location. This should be used instead of :INDEX also for Maildir/mbox to improve performance. + Improved mailbox list indexes. They should be usable now, although still disabled by default. + Added LAYOUT=index. The mailbox directories are created using their GUIDs in the filesystem, while the actual GUID <-> name mapping exists only in the index. + LMTP proxy: Implemented XCLIENT extension for passing remote IP address through proxy.
