[Dovecot] mdbox: Is there any more info on the "cleanup" step? (Dovecot 2.0beta5)
by William Blunn 26 May '10

26 May '10

The wiki page which mentions mdbox talks about a "cleanup" step for mdbox: : The space is later freed in "cleanup" step. This may be done : automatically within the session or later in a nightly cronjob when : there's less disk I/O. The cleanup first finds all files that have : refcount=0 mails. Then it goes through each file and copies the : refcount>0 mails to other dbox files (to the same files as where newly : saved messages would also go), updates the map index and finally : deletes the original file. So there is never any overwriting or file : truncation. I was wondering if there was any code to actually do this, or any command-line tools (and if either of those where they might be), or whether it was just design musings at the minute. Regards, Bill

[Dovecot] mdbox: What format is the file "storage/dovecot.map.index" in? (Dovecot 2.0beta5)
by William Blunn 26 May '10

26 May '10

I am looking at "mdbox" under Dovecot 2.0beta5. Looking at the documentation for "mdbox" I saw that we had a directory "storage" containing files "m.#" where "#" is an integer and a map file ("dovecot.map.index"). I think I expected the map file to be a plain text file with one record per line, but in fact it appears to contain binary data. According to the wiki ( http://wiki.dovecot.org/MailboxFormat/dbox ) the records go as: - map_uid: Unique growing 32 bit number for the message. - refcount: 16 bit reference counter for this message. Each time the message is copied the refcount is increased. - file_id: File number containing the message. For example if file_id=5, the message is in file m.5. - offset: Offset to message within the file. - size: Space used by the message in the file, including all metadata. The map file I have here is 1688 bytes in size (and I think there are 64 messages stored). Prime factors of 1688 are 2^3 x 211, so I think it is something other than just a straight array of fixed-size structures. Still, I can always look at the source if I really want to know :-) Regards, Bill

But the whole point of the code is to get number of affected rows for previous UPDATE, so that if there is no quota row for user, the quota gets recalculated. This fixed it for my tests: http://hg.dovecot.org/dovecot-2.0/rev/0c15a760dab8

[Dovecot] newbie question about shared folders
by Tom Lieuallen 26 May '10

26 May '10

I'm preparing to move our site to dovecot 1.2.11 and have a question about shared folders. We're currently using UW imap's mbx mailboxes for shared folders. We accomplish the sharing by use of file system permissions and ACLs. I notice that dovecot's method of sharing is more based on IMAP ACLs and apparently file system permissions are useful, but not necessary. On the main dovecot page, it says: "Dovecot allows mailboxes and their indexes to be modified by multiple computers at the same time..." So, my question is whether I need to use the dovecot imap sharing namespace in order to safely share imap folders, or whether I can just use file system permissions as we have been using? My biggest concern is safe concurrent access to the shared folders, which I'm planning to implent with mbox files for now. thank you Tom Lieuallen Oregon State University College of Engineering

[Dovecot] Busy looping of 2.0Beta4 on NetBSD-current
by Scott Ellis 26 May '10

26 May '10

I built and install Dovecot 2.0Beta4 on my NetBSD/amd64-current system, and am seeing the user-owned imap processes busy-looping. In Dovecot 1.2.x (and 1.x and 0.x..) I force ionotify and ioloop to kqueue, so I suspected that was the problem. Turns out it's not: Using poll or none also causes the same problem. This did not happen in 1.2.8 (didn't try anything later than that). After a quick visit to gdb, I added some i_debug() statements in ioloop-kqueue.c (when I had that as the notify and loop method) which showed that the loop was in io_loop_handler_run() . I haven't done any similar debugging for the other ioloop methods, but a quick look at the 2.0 changelog for those files doesn't raise any immediate alarms. Any ideas what to look for here? Timo, any ideas? 1.2.x worked perfectly so it's something "new" in 2.0. ScottE

[Dovecot] quota and lazy_expunge plugins both used: quotas go wrong with lazy_expunge'd mails
by Baptiste Malguy 26 May '10

26 May '10

Hello, I may have missed a point, but I could have found an issue between plugins quota and lazy_expunge. I have noticed that the "lazy_expunge"d mails are counted as part of the quota, while the documentation says it should not be. I have first tried to find out if this was a configuration mistake somewhere. Notably, you can notice that the expunged mails are in directory ~/expunged while the usual mail is in ~/Maildir : expunged mails are not in a subdirectory of ~/Maildir (this was just to make sure there were no side effect with this). I have deleted some expunged mails to be sure : at its next cycle, the file ~/Maildir/maildirsize contained expected value. So yes, I do know expunged mails in the expunged directory are counted (size, number of mails). So I've taken a look at the source code, adding some i_info(...) at different places of the quota and lazy_expunge plugins. >From the source code reading session, I understand that : 1. In src/lazy-expunge/lazy-expunge-plugin.c 1.1. lazy_expunge_mail_storage_init() sets the expunged mails namespace flag with NAMESPACE_FLAG_NOQUOTA 1.2. lazy_expunge_mail_storage_init() is called by lazy_expunge_mail_storage_created() 1.3. lazy_expunge_mail_storage_created() is part of the callback list hook_mail_storage_create 2. In src/plugins/quota/quota-storage.c: 2.1. The only place in the whole dovecot source code where NAMESPACE_FLAG_NOQUOTA is checked is in function quota_mailbox_list_created() 3. In src/plugins/quota/quota-plugin.c: 3.1 quota_plugin_init() add quota_mailbox_list_created() to the callback list hook_mailbox_list_created. >From my observations : - Callback functions in quota_mailbox_list_created are called _before_ callback functions in hook_mail_storage_create. - This observation led me to move the piece of code that sets NAMESPACE_FLAG_NOQUOTA from lazy_expunge_mail_storage_init() to lazy_expunge_mail_storage_created(). - But there, lazy_expunge_mail_storage_created() is called after quota_mail_storage_created() because names of the library files are lib10_quota_plugin.so and lib02_lazy_expunge_plugin.so. - There I have also learnt that callback functions of the same list are called in the reverse order compared to the library filenames. So see if my observations were right, I have renamed lib10_quota_plugin.so to lib01_quota_plugin.so, then it worked. But I doubt this is the right way to fix it. This also reverses the order other callbacks between the two plugins are called, which migh not be expected at all. I'm not event sure moving some code from lazy_expunge_mail_storage_init() to lazy_expunge_mail_storage_created() was right : I've improvized the reading the source code and do not understand the whole logic, so I suppose this could break something else. Timo, what do you propose ? Thanks for your great software. -- Baptiste MALGUY PGP fingerprint: 49B0 4F6E 4AA8 B149 B2DF 9267 0F65 6C1C C473 6EC2

[Dovecot] Zlib plugin dovecot 2.0beta4
by Alex Baule 26 May '10

26 May '10

Hi Timo... I made the plugin like you say. The header part is saved by dovecot, with o_stream_send , and the body with my function. This implementation, works fine. But i need to get / change some values to create the "link" from header to body. When a email is saved, have the S an W flags, that is the size of email. There is a way to increase this Flags ? I need to put one more line in the header, to have some link to body. To Increase the S Flag i increase the ostream.offset, but the W is based in the offset from istream, that's right ? There is a way to do this without rewrite the read function !? Exemple, when the email is moved from tmp to cur.

[Dovecot] proxy user wildcard
by Martin Ott 26 May '10

26 May '10

Hi, I'd like to try dovecot as a imapproxy in front of a webmailer. Authentication should be done by the main dovecot-imapserver. It works if I specify the user in passdb passwd-file: user2::0:0::::proxy=yes host=[ip-address] ssl=any-cert starttls=yes nopassword=y Is there some kind of catch-all function to pass all users to the main dovecot-imapserver without knowing the valid users? dovecot: 1.2.9 thx Martin

[Dovecot] Plugins and message file access
by Reinaldo Matukuma 26 May '10

26 May '10

Hello. I need to know how I can get the final message file name inside a plugin like the zlib 2.0 plugin. I saw another threads about zlib plugin, but don't see no one asking about this. My interest is to use the message's file name in a specific function that will add some lines on it and, after that, calculate a md5 hash of the modified file. As the size flags will not correspond to the effective message size/vsize, then I could change the flags using the filename too, right? This is my first approach. But... There are another way to do this directly on message been received by the plugin, like pre-allocating the size/vsize flags? I cannot simply to pass the extra text directly on the message being received because I need to do some extra validations over the full content of the message before add my data on the message.

[Dovecot] corrupted transaction log errors causing users mail to disappear temporarily
by Jordan Tardif 26 May '10

26 May '10

So Ive been looking into some problems with users reporting their mail goes missing for a second but then re-apears very soon after. I have tracked it down to happening at the same time these appear in the logs. Seems the transaction logs is getting corrupted somehow and then rebuilding itself (which works fine). The problem is while its re-builing the users think all of their mail is gone.

[Dovecot] Where should I define mail_uid for deliver LDA?
by Alex 26 May '10

26 May '10

Hello folks I'm trying to use Dovecot deliver LDA instead Postfix virtual LDA The last road block I have to resolve is to define mail_uid, becaus dovecot.err log has these error messages: May 04 14:57:19 deliver(user1(a)some_domain.com): Error: User user1(a)some_domain.com is missing UID (set mail_uid) May 04 14:57:19 deliver(user2(a)some_domain.com): Error: User user2(a)some_domain.com is missing UID (set mail_uid) May 04 14:57:25 deliver(user3(a)some_domain.com): Error: User user3(a)some_domain.com is missing UID (set mail_uid) Where exactly should I define mail_uid? Somewhere in Dovecot dovecot.conf file? I tried to set mail_uid in dovecot-sql.conf in user_query as follows: user_query = SELECT maildir as mail, 51 as userdb_uid, 51 as userdb_gid, 51 as mail_uid FROM dovecot_email_maps WHERE email = '%u' But this apparently doesn't provide that mail_uid as I expected. Could somebody please enlighten me on this issue. Thank you in advance, Alex

Hi, I'm using RoundCube and I asked RC team to add ACL support, but there is a problem with renaming ACL protected folders. Users don't have permissions to deleting/renaming some folders.

[Dovecot] mixture of virtual and plain users
by Kapetanakis Giannis 26 May '10

26 May '10

Hi, I have a mail server (postfix/dovecot) running so far with normal local /etc/passwd users for domain example.com. mail_location = maildir:~/Maildir passdb pam { } userdb passwd { } Is it possible to add virtual domains/users to my setup without changing example.com to a virtual domain? I can do the postfix part with http://www.postfix.org/VIRTUAL_README.html#virtual_mailbox but I'm not sure if I can mix dovecot (IMAP and maybe smtp auth) for both local and virtual users. Any hint would be appreciated. best regards, Giannis

[Dovecot] libdovecot not referencing libiconv

[Dovecot] Bug in zlib Plugin (2.0)
by Alex Baule 26 May '10

26 May '10

Hello everyone..... I Made some tests in zlib plugin, and in ostream file (ostream-zlib.c) in o_stream_zlib_sendv function, have it: stream->ostream.offset += bytes; In struct mail_save_context, have saved_physical_size and it can be updated, acording with the observation. /* if non-zero, overrides the physical size that should be saved. for example when using zlib plugin, this would contain the mail's uncompressed size. */ uoff_t saved_physical_size; in file zlib-plugin.c in zlib_mail_save_compress_finish function, have it: ctx->saved_physical_size = ctx->output->offset; It's a update to offset (the size of email) in zlib, but if you update this value with a new number, the W flag in email is NOT updated. This is the original file, without update the or increase offset. 1273155226.M512158P16310.brc,S=435,W=390:2,S This is the file updated with 5000b more. 1273155226.M512158P16310.brc,S=5435,W=390:2,S The S is updated, but W not. OK, this not matter in zlib plugin, because the physical size is the email uncompressed, but if you use the zlib as example, and you use this value (saved_physical_size) to update your saved email size, it can't update the W flag, and the email will not be open, because the W size is wrong.

[Dovecot] A few questions on shared folders
by Michael Durket 26 May '10

26 May '10

I'm looking at the possibility of using shared folders to solve a particular problem for my employer and I have a few questions: 1) Can shared folders be in mbox format while allowing the user's mail to be in maildir format? (I think the answer is yes, but wanted to check). 2) What version of dovecot should I be running in order to support shared folders? 3) Is there a good overview document that people could recommend I read that describes how best to set up shared folders under dovecot (and perhaps also gives an overview of shared folder usage in IMAP mail clients in general)? Thanks very much, Michael Durket

[Dovecot] STARTTLS does not seem to work
by Phil Howard 26 May '10

26 May '10

I believe I have the configuration set to use START TLS on IMAP4 (143) and POP3 (110) ports. However, it does not seem to be working. Yet "STARTTLS" is listed as a capability (which tells me I probably do have it configured right). In the session below, 172.30.0.24 is the mail server I'm putting up. 64.26.60.229 is an outside mail service. A similar thing happens on POP3. The always-SSL/TLS ports (993 and 995) are working. There's very little documentation matching "starttls". ======================================================================== altair/phil /home/phil 162> telnet 172.30.0.24 143 Trying 172.30.0.24...

[Dovecot] config file includes
by Tim Traver 26 May '10

26 May '10

Hi all, ok, I couldn't quite find this in any of the documentation, so I figured I would ask here. In preparation to move to version 2.0 to take advantage of the mutiple IP and SSL cert options that are coming, it would be really nice to be able to include other config files in the main config file, so that I don't have to edit the main config in order to add new IP addresses or certs... Does dovecot currently have the ability to include another config file when it is parsing the main config??? If not, is that something that we can put on the wish list? Thanks, Tim.

[Dovecot] Problems with the fs-quota plugin on delivery stage
by Kostik 25 May '10

25 May '10

Hi All! Just noticed a strange behavior of the FS quota plugin on delivery stage. We use group FS quotas via NFS. And quota-tool says: --- Disk quotas for group #5751796 (gid 5751796): Filesystem blocks quota limit grace nfse:/export 1276 10240 10240 --- I run: --- cat ./test.eml | /usr/local/libexec/dovecot/deliver -e -n -d xxxx(a)xxxxx.xxxx --- and get: --- Quota exceeded (mailbox for user is full) --- But ./test.eml is 7088147 bytes and it is not above the quota. dovecot debug log is: --- May 12 20:01:46 dovecot: deliver(xxxx(a)xxxxx.xxxx): fs quota block device = nfse:/export May 12 20:01:46 dovecot: deliver(xxxx(a)xxxxx.xxxx): fs quota mount point = /mount/m5 May 12 20:01:47 dovecot: deliver(xxxx(a)xxxxx.xxxx): quota-fs: host=nfse, path=/export, gid=5751796, bytes May 12 20:01:47 dovecot: deliver(xxxx(a)xxxxx.xxxx): quota-fs: gid=5751796, value=8409088, limit=10485760, active=1 May 12 20:01:47 dovecot: deliver(xxxx(a)xxxxx.xxxx): from=<xxxx(a)xxxxx.xxxx>, msgid=<4BEA4744.1040701@xxxx@xxxxx.xxxx>: save failed to INBOX: Quota exceeded (mailbox for user is full) --- It seems that "value=8409088, limit=10485760" shows that the quota is no problem, but "save failed". If I become that user, then no problems. I can copy ./test.eml without problems. Now quota-tool says: --- Filesystem blocks quota limit grace nfse:/export 8212 10240 10240 --- If I try to copy again(over quota), then honestly get: --- cp: closing `./test2.msg': Disk quota exceeded --- If I switch off quota plugin on dovecot.conf (LDA specific settings), then: - 1. The first delivery is without error, but the INBOX is corrupted(last msg is clipped) but quota-tool show only 3300 blocks used (quota is 10240 blocks). - 2. Following delivery big msgs (over quoted) ends with an error: "Not enough disk space" (this is correct, because the quota is really ended) - 3. Following delivery small msgs (above quoted) ends well, msgs are delivered (used 3304 blocks and etc.) Our setup: -- slackware 11.0, x86_32 -- linux 2.6.31.6 -- dovecot 1.2.11 -- mailbox(not maildir) via NFS storage. Please, tell me where to start looking for the problem? =kostik

[Dovecot] (1.2.11): Confused about shared/public folders
by Denny Schierz 25 May '10

25 May '10

hi, i red several hours a lot of documentation (wiki, Blogs, lists ...) how to get public folders. Under cyrus it is very easy. Create a mbox on the top with cyradm and some acls. Nothing more ... All i want is: public/info public/group/internal public/foo public/foo/bla on info, everybody can read on group/internal - only group has full access to internal public/foo/bla - read write for everyone The flags (seen, ...) is stored for all. The wiki entries are to old or mixing several things and are not clear, what I should do, to get it working. my config: dovecot.conf mail_location = maildir:/imap/domain/%1n/%n:INDEX=/imap/indexes/domain/% 1n/%n namespace private { separator = / prefix = inbox = yes } #namespace shared { # separator = / # prefix = shared/%%u/ # location = maildir:/imap/shared/domain/%1n/% n:INDEX=mbox:/imap/shared/domain/%1n/%n # subscriptions = no # list = yes #} namespace public { separator = / prefix = public/ location = maildir:/imap/shared/domain subscriptions = no list = yes } mail_uid = vmail mail_gid = vmail mail_privileged_group = vmail protocol imap { login_executable = /usr/local/dovecot/dovecot/libexec/dovecot/imap-login mail_executable = /usr/local/dovecot/dovecot/libexec/dovecot/imap mail_plugin_dir = /usr/local/dovecot/dovecot/lib/dovecot/imap/ mail_plugins = quota imap_quota imap_idle_notify_interval = 120 fsync_disable = yes mail_plugins = quota imap_quota acl imap_client_workarounds = outlook-idle netscape-eoh } plugin { acl = vfile acl_shared_dict = file:/imap/rbg/acl/shared-mailboxes.db acl = vfile:/imap/rbg/acl/dovecot-acls } I wasn't able to use under plugins imap_acl, cause of errors: open(/usr/local/dovecot/dovecot/lib/dovecot/imap//lib02_imap_acl_plugin.so) failed: ld.so.1: imap: fatal: relocation error: file /usr/local/dovecot/dovecot/lib/dovecot/imap//lib02_imap_acl_plugin.so: symbol acl_mailbox_right_lookup: referenced symbol not found Couldn't load required plugins Error: imap dump-capability process returned 89 Fatal: Invalid configuration in /usr/local/dovecot/1.2.11/etc/dovecot.conf System is Solaris10, build by my self with Sieve Patches. After changing to "acl" only, DoveCot starts. So, i can see in Roundcube (webmail) the folder Public (or shared, from the above example) but nothing more. Do i need symlinks, or what I have to do after create the folder + permissions? cu denny

[Dovecot] order of variable modifiers
by Phil Howard 25 May '10

25 May '10

I'd like to have a variable substitute take the domain name part, lower case it, MD5 it, and take a 2-character substring of that. Would that be like %2MLd ? The documentation on the H hash modifier described reversing with R, but expresses it at %3RHu which seems to me like it would be reversing the hash result rather than the user string. I'm undecided about MD5 vs. hash, and could go either way. But I was thinking: mail_location = /data/mail/%2MLd/%Ld/%2MLn/%Ln

[Dovecot] per domain quota
by alex 25 May '10

25 May '10

Hi I'am using dovecot with quota_rule stored in mysql user table, and quota usage stored in mysql dict ###### Quota ############# dict { quotadict = mysql:/usr/local/etc/dovecot-quota.conf } plugin { quota = dict:user::proxy::quotadict quota_rule2 = Trash:storage=10%% quota_rule3 = Sent:ignore #quota_rule = *:storage=10M } ################################### Everything works as expected, but I have some inconveniences for domains with large number of mailboxes. Allocating and maintain quota to every account it's a hard job. I just want to implement some flexibility for this situations (ex the first enforcement to be the user quota and the second to be the domain quota). Is there a way to implement such thing in dovecot and what are the adjustments that I need to do. Regards Alex

[Dovecot] v2.0.beta5 released
by Timo Sirainen 25 May '10

25 May '10

http://dovecot.org/releases/2.0/beta/dovecot-2.0.beta5.tar.gz http://dovecot.org/releases/2.0/beta/dovecot-2.0.beta5.tar.gz.sig Sorry for being so quiet recently. Unfortunately I think it's still going to last a while longer. I'll be in Italy for next two weeks and immediately after that I'll move to Portugal. I'll probably write something about that later to blog. I had hoped that this beta5 would be almost the same as RC1, but I didn't have time to put everything there yet, and thought beta4 is way too old already. The few things that should still be done: - Change expire-tool to be a plugin for doveadm expunge command - doveadm mailbox * commands should use UTF-8 for mailbox names, not mUTF-7 (and add -7, -8 parameters to switch between them) - THREAD command seems to be crashing - some other bugfixes Some of the changes since beta4: - default_login_user is now "dovenull". You should create this user. - imap, pop3 -u <user> now does userdb lookup + changes privileges if necessary, so it's much easier to start imap/pop3 session for a specific user from command line - doveadm has all kinds of new commands and changes - PostgreSQL supports now multiple connections to backend. Also supports load-balancing / HA by specifying multiple host parameters. MySQL and PostgreSQL now share the same code for that. - probably lots of other things I can't think of right now. h

[Dovecot] about acl
by Yavuz Maşlak 25 May '10

25 May '10

I use dovecot, vpopmail. I wish to restrict a mail user's login to its mailbox according to its ip address. I don't wish other users to be affected . Namely, for instance, abc(a)domain.com can login to its mailbox from a few specific ip addresses but the same user will not able to login from anywhere. Meanwhile normally other mail users can login to their mailboxes from all ip addresses. How can I do that with dovecot acl ? any advice.

[Dovecot] suggestion
by Andreas Schulze 25 May '10

25 May '10

hello, dovecot2 implements "!include conf.d/*.conf" to build the configuration from multiple configfiles. So the settings for pop3, imap or lmtp may stay in different files. unfortunately the "protocol = " does not allow a += logic to enables or disable inet listeners. It would be nice to have protocols += imap in conf.d/imap.conf and protocols += managesieve in conf.d/managesieve.conf This would make the include feature more consistent... or is it already possible ? -- Andreas Schulze Internetdienste | P532 DATEV eG 90329 Nürnberg | Telefon +49 911 319-0 | Telefax +49 911 319-3196 E-Mail info @datev.de | Internet www.datev.de Sitz: 90429 Nürnberg, Paumgartnerstr. 6-14 | Registergericht Nürnberg, GenReg Nr.70 Vorstand Prof. Dieter Kempf (Vorsitzender) Dipl.-Kfm.

[Dovecot] List shared folders
by Marcio Merlone 25 May '10

25 May '10

Good morning! I run an imap-only Ubuntu 8.04 mail server with dovecot 1.2 and pam_ldap, so all my users are posix users. No virtual user or domain, no sql so far. I am setting up shared folders with "namespace shared". I got no errors upon restarting the service, but I get no shared folders listing. As per the wiki http://wiki.dovecot.org/SharedMailboxes/Shared I can use a bdb file or sql connection to keep the listing. But when I use a single bdb file like: plugin { acl_shared_dict = file:/var/lib/dovecot/shared-mailboxes.db } everytime a user logs in, this file get its ownership to the user with 0600 mode. I could use an sql dictionary, but since I dont have any sql params on my configs I am not sure where to store connection params like user, password and host for database. Can anybody help me with that? My goal is to allow my users to shared selected folders with other users, hope to be in the right path. Thanks and regards. -- Marcio Merlone

[Dovecot] Setting up ACL for IMAP
by Andrés Gattinoni 25 May '10

25 May '10

Hi guys, I just suscribed cause I'm trying to do something which I'm not sure how. I need to prevent some accounts from deleting there emails. >From what I've seen [0] this could be achieved by using ACL. My first question is, is this right? Is there a way to achieve the same using POP3? I tried setting up ACL using the info at the Wiki [1], but it's not working.

[Dovecot] SSL Bug
by Matthew Sackman 25 May '10

25 May '10

Hi, After many hours of testing, I've finally tracked down the issue I have been having with dovecot's SSL support. The problem is that the SSL certs result in "TLS handshaking: SSL_accept() syscall failed: Connection reset by peer" errors *if the certificate granted is not granted for client use*. For servers, I normally generate SSL certificates specifically for servers: [ server_ca_extensions ] basicConstraints = CA:false keyUsage = keyEncipherment extendedKeyUsage = 1.3.6.1.5.5.7.3.1 If you just do that, then the SSL certificate doesn't work in dovecot (it will work fine in Apache, or Postfix etc etc). You also need the certificate to be valide for client side work: [ client_and_server_ca_extensions ] basicConstraints = CA:false keyUsage = digitalSignature, keyEncipherment extendedKeyUsage = 1.3.6.1.5.5.7.3.2, 1.3.6.1.5.5.7.3.1 I believe this is a fault with Dovecot. This is with the Debian package for Dovecot 1.2.11 (Version: 1:1.2.11-1). The default self-signed certificate the Debian post-install script generates pops out a certificate that is valid for everything, which is why it works by default out of the box. Matthew

[Dovecot] Plugin to encrypt mailboxes ?
by Frank Bonnet 25 May '10

25 May '10

Hello Is there a possibility for my users to encrypt their mailboxes through Dovecot ? They haven't direct access to the server, IMAP & IMAPS only. We use Thunderbird as client and mailboxes are in MBOX format Dovecot is running on a FreeBSD 7.2 server. Thanks a lot

[Dovecot] dovecot/deliver ... Can't open log file /var/log/dovecot/error.log: Permission denied
by Phil Howard 24 May '10

24 May '10

I'm getting this ... May 10 12:45:01 eth0 postfix/local[3416]: A788D685F7: to=< xxxxxxxx(a)xxxxxxxx.net>, relay=local, delay=13, delays=13/0/0/0.03, dsn=4.3.0, status=deferred (temporary failure. Command output: Can't open log file /var/log/dovecot/error.log: Permission denied ) So I'm looking at http://wiki.dovecot.org/LDA to see what I can do about it. I would have hoped some comments in the example config file would have mentioned this and suggested a default practice solution. Is this something few people or many people encounter (among those using dovecot/deliver from Postfix)? If I do as the wiki describes and make separate log files for dovecot/deliver to use, do I just make them owned by Postfix? It would seem to me a different directory might be more helpful (absent log files could be created by having the directory permissions. I'm also thinking in terms of log rotations, too ... and I prefer to do log rotations by date stamping rather than pushing sequence numbers (the legacy log rotation). Any chance there are %-style variables I can use in log file/path names to make log files automatically named by the date (and maybe time) ... kind of like in a shell script I would do: `date +/path/to/tree/%Y/%m/%d.log` or such.

[Dovecot] Thunderbird very slow startup, 1.2.11, mbox, postfix local delivery to /var/mail
by Stan Hoeppner 22 May '10

22 May '10

I've Google'd to exhaustion and can't seem to find an answer to my problem. I'm not sure if the problem is TBird 3 or my Dovecot setup. The basic problem is that when I launch TBird and it grabs messages upon startup, it takes forever to supposedly pull them down. Once it's got them they sort relatively quickly into the proper IMAP (dovecot) folders. I don't use sieve yet; I sort with TBird rules. I don't sync messages for offline use. The only thing TB stores locally is the index cache, which I deleted and had TB rebuild once, which didn't help. All that did was waste more time, as I've got 40,000 messages in my IMAP folders which had to be re-indexed by TB. (I save all list mail for future searching). As an example of this problem, I'd not checked my email for just over day, had ~300 messages waiting in /var/mail/stan. TBird starts pulling them from dovecot and says in the status bar "downloading x of ~300". As I watch the count tick up +10 at a whack, the TB process is pegged at 100%, there is zero network activity, and the imap process on the server shows zero cpu use. It took over 60 seconds to "pull" the messages, after which TB sorted them. During the apparent sorting process, there is quite a bit of network activity and the imap process on the server is relatively busy. I say "pull" in quotes because the entire time TB is saying it's pulling more messages there is no network activity. The client and server are plugged into the same 100BaseT FDX switch (FDX verified), and the server has zero load. I know TBird isn't the greatest IMAP client around, but I think taking over 60 seconds just to download ~300 messages is way too damn long given the hardware resources, network, and load on the client and server machines. TB basically seems to be pulling, or dovecot serving, only about 5 messages/sec over 100Mb ethernet, which is abysmal performance given neither the server nor client have any load. The messages are mostly list mail which are at max a few kilobytes each. I'm leaning toward a problem with TBird but I've been unable to find a bug report that covers this, nor a forum post anywhere, etc. The closest I've found for "slow startup" are recommendations to compact folders. I have no local folders to compact. I delete immediately and expunge on exit. Anyone have any ideas? Other than switching to LDA+sieve and have TB check the IMAP folders for new mail? -- Stan

Hi I've just compiled dovecot under Slitaz, but I can't get it to run...

[Dovecot] Dovecot and /dev/shm
by DJ GRP 22 May '10

22 May '10

Hi, I have tried to use /dev/shm for Dovecot's index files: > mail_location = mbox:~/mail:INBOX=/var/mail/%u:INDEX=/dev/shm/%u But it does not seem to like it. May 21 07:13:59 IMAP(user): Error: stat(/dev/shm/user/.imap/INBOX) failed: Permission denied (euid=1234(user) egid=500(group) missing +x perm: /dev/shm) It seems to me that /dev/shm permissions are OK. Any suggestions on how to achieve this?

[Dovecot] Patch for logging variables
by James Devine 20 May '10

Upon thinking, the variable names may not be descriptive enough as `host` is a bit ambiguous and `deleted_count` may refer to a different command than expunge in imap and may be valid to track at some point so I have changed `host` to `client_ip` and `deleted_count` in imap to `expunged_count`, below is the modified diff for version 1.2.11. diff -crB dovecot-1.2.11.orig/src/imap/client.c dovecot-1.2.11/src/imap/client.c *** dovecot-1.2.11.orig/src/imap/client.c 2010-01-24 16:14:17.000000000 -0700 --- dovecot-1.2.11/src/imap/client.c 2010-05-20 09:30:47.170407921 -0600 *************** *** 42,47 **** --- 42,48 ---- client->fd_out = fd_out; client->input = i_stream_create_fd(fd_in, imap_max_line_length, FALSE); client->output = o_stream_create_fd(fd_out, (size_t)-1, FALSE); + client->expunged = 0; o_stream_set_flush_callback(client->output, client_output, client); *************** *** 105,110 **** --- 106,113 ---- static struct var_expand_table static_tab[] = { { 'i', NULL, "input" }, { 'o', NULL, "output" }, + { 'c', NULL, "client_ip" }, + { 'e', NULL, "expunged_count" }, { '\0', NULL, NULL } }; struct var_expand_table *tab; *************** *** 115,120 **** --- 118,125 ---- tab[0].value = dec2str(client->input->v_offset); tab[1].value = dec2str(client->output->offset); + tab[2].value = getenv("IP") ? getenv("IP") : "Unknown"; + tab[3].value = dec2str(client->expunged); str = t_str_new(128); var_expand(str, logout_format, tab); diff -crB dovecot-1.2.11.orig/src/imap/client.h dovecot-1.2.11/src/imap/client.h *** dovecot-1.2.11.orig/src/imap/client.h 2009-06-26 22:49:34.000000000 -0600 --- dovecot-1.2.11/src/imap/client.h 2010-05-19 16:26:31.529833893 -0600 *************** *** 133,138 **** --- 133,139 ---- unsigned int destroyed:1; unsigned int handling_input:1; unsigned int syncing:1; + unsigned int expunged; unsigned int id_logged:1; unsigned int mailbox_examined:1; unsigned int input_skip_line:1; /* skip all the data until we've diff -crB dovecot-1.2.11.orig/src/imap/cmd-close.c dovecot-1.2.11/src/imap/cmd-close.c *** dovecot-1.2.11.orig/src/imap/cmd-close.c 2010-01-24 16:14:17.000000000 -0700 --- dovecot-1.2.11/src/imap/cmd-close.c 2010-05-19 16:26:31.529833893 -0600 *************** *** 18,24 **** client->mailbox = NULL; storage = mailbox_get_storage(mailbox); ! if ((ret = imap_expunge(mailbox, NULL)) < 0) client_send_untagged_storage_error(client, storage); if (mailbox_sync(mailbox, 0, 0, NULL) < 0) client_send_untagged_storage_error(client, storage); --- 18,24 ---- client->mailbox = NULL; storage = mailbox_get_storage(mailbox); ! if ((ret = imap_expunge(client, NULL)) < 0) client_send_untagged_storage_error(client, storage); if (mailbox_sync(mailbox, 0, 0, NULL) < 0) client_send_untagged_storage_error(client, storage); diff -crB dovecot-1.2.11.orig/src/imap/cmd-expunge.c dovecot-1.2.11/src/imap/cmd-expunge.c *** dovecot-1.2.11.orig/src/imap/cmd-expunge.c 2010-01-24 16:14:17.000000000 -0700 --- dovecot-1.2.11/src/imap/cmd-expunge.c 2010-05-19 16:26:31.529833893 -0600 *************** *** 24,30 **** { struct client *client = cmd->client; ! if (imap_expunge(client->mailbox, search_args == NULL ?

[Dovecot] Dovecot LDAP problems
by Adam Pardy 20 May '10

20 May '10

I'm currently trying to configure a linux mailserver running centos to use an xserve running snow leopard. I am configuring the mailserver to run dovecot,sendmail,clamav,spam assassin and squirrelmail so it matches those used by the mac. The problem I am having is that I cannot get the server to authenticate properly to the macs LDAP database. As far as I can tell it is either a problem authenticating passwords or username and passwords. mail.app says its the password it cant authenticate Thunderbird says it could be either. It seems to be a problem in dovecot-ldap.conf, (as I can run ldapsearch from the linux server authenticate correctly and gain user information) What I'd like to know is there a standard set of settings required to authenticate to the LDAP on the mac? I'm currently running the od with no requirements for Kerberos, SSL or anything else it can authenticate with plain passwords (it will be once it is implemented I'm trying to have as few variables as possible at the moment). Copy of dovecot-ldap.conf below; 1. This file is opened as root, so it should be owned by root and mode 0600. # 1. http://wiki.dovecot.org/AuthDatabase/LDAP # 1. NOTE: If you're not using authentication binds, you'll need to give 2. dovecot-auth read access to userPassword field in the LDAP server. 3. With OpenLDAP this is done by modifying /etc/ldap/slapd.conf. There should 4. already be something like this: 1. access to attribute=userPassword 2. by dn="<dovecot's dn>" read # add this 3. by anonymous auth 4. by self write 5. by * none 1. Space separated list of LDAP hosts to use. host:port is allowed too. hosts =hostname.com 1. LDAP URIs to use. You can use this instead of hosts list. Note that this 2. setting isn't supported by all LDAP libraries. #uris = 1. Distinguished Name - the username used to login to the LDAP server dn= uid=wmuser,cn=#####,dc=##,dc=###########,dc=### 1. Password for LDAP server dnpass = password 1. Use SASL binding instead of the simple binding. Note that this changes 2. ldap_version automatically to be 3 if it's lower. Also note that SASL binds 3. and auth_bind=yes don't work together. #sasl_bind = no 1. SASL mechanism name to use. #sasl_mech = 1. SASL realm to use. #sasl_realm = 1. SASL authorization ID, ie. the dnpass is for this "master user", but the 2. dn is still the logged in user. Normally you want to keep this empty. #sasl_authz_id = 1. Use TLS to connect to the LDAP server. #tls = no 1. Use authentication binding for verifying password's validity. This works by 2. logging into LDAP server using the username and password given by client. 3. The pass_filter is used to find the DN for the user. Note that the pass_attrs 4. is still used, only the password field is ignored in it. Before doing any 5. search, the binding is switched back to the default DN. auth_bind = yes 1. If authentication binding is used, you can save one LDAP request per login 2. if users' DN can be specified with a common template. The template can use 3. the standard %variables (see user_filter). Note that you can't 4. use any pass_attrs if you use this setting. # 1. If you use this setting, it's a good idea to use a different 2. dovecot-ldap.conf for userdb (it can even be a symlink, just as long as the 3. filename is different in userdb's args). That way one connection is used only 4. for LDAP binds and another connection is used for user lookups. Otherwise 5. the binding is changed to the default DN before each user lookup. # 1. For example: auth_bind_userdn = cn=%u,cn=users,dc=##,dc=###########,dc=### # #auth_bind_userdn = 1. LDAP protocol version to use. Likely 2 or 3. ldap_version = 3 1. LDAP base. %variables can be used here. base = dc=##, dc=###########, dc=### 1. Dereference: never, searching, finding, always #deref = never 1. Search scope: base, onelevel, subtree #scope = subtree 1. User attributes are given in LDAP-name=dovecot-internal-name list. The 2. internal names are: 3. uid - System UID 4. gid - System GID 5. home - Home directory 6. mail - Mail location # 1. There are also other special fields which can be returned, see 2. http://wiki.dovecot.org/UserDatabase/ExtraFields user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid 1. Filter for user lookup. Some variables can be used (see 2. http://wiki.dovecot.org/Variables for full list): 3. %u - username 4. %n - user part in user@domain, same as %u if there's no domain 5. %d - domain part in user@domain, empty if user there's no domain user_filter = (&(objectClass=posixAccount)(uid=%u)) 1. Password checking attributes: 2. user: Virtual user name (user@domain), if you wish to change the 3. user-given username to something else 4. password: Password, may optionally start with {type}, eg. {crypt} 5. There are also other special fields which can be returned, see 6. http://wiki.dovecot.org/PasswordDatabase/ExtraFields pass_attrs = uid=user,userPassword=password 1. If you wish to avoid two LDAP lookups (passdb + userdb), you can use 2. userdb prefetch instead of userdb ldap in dovecot.conf. In that case you'll 3. also have to include user_attrs in pass_attrs field prefixed with "userdb_" 4. string. For example: #pass_attrs = uid=user,userPassword=password 1. Filter for password lookups pass_filter = (&(objectClass=posixAccount)(uid=%u)) 1. Default password scheme. "{scheme}" before password overrides this. 2. List of supported schemes is in: http://wiki.dovecot.org/Authentication default_pass_scheme = PLAIN 1. You can use same UID and GID for all user accounts if you really want to. 2. If the UID/GID is still found from LDAP reply, it overrides these values. #user_global_uid = #user_global_gid =

[Dovecot] LDAP against Novell eDirectory: 'Confidentiality required'

Hi list! I am trying to get dovecot to authenticate users against Novell eDirectory via LDAP. I have successfully gotten open-xchange to authenticate, and I have written a PHP module that authenticates, however I cannot seem to get Dovecot working.

[Dovecot] POP3 Problem with SPAM-Mail's over sieve
by Michael Niehren 20 May '10

20 May '10

Hi together, i am currently using dovecot 1.2.10 with the sieve-plugin and use a sieve-filter to sort the SPAM-Mail's directly into a Junk-Folder: require "fileinto"; # rule:[junkfilter] if header :contains "X-Spam-Flag" "YES" { fileinto "Junk"; } My problem is now, if i try to retrieve the Mails via POP3, i did not get the SPAM-Mail's in the Junk-Folder, only the normal ones, that are not filtered over the sieve plugin. Could anyone tell me how to solve that issue ? best regards Michael -- Michael Niehren __ _ powered by / / (_)__ __ ____ __ / /__/ / _ \/ // /\ \/ / /____/_/_//_/\_,_/ /_/\_\

hi, we have IMAP and SMTP (sendmail(solaris)) on different hosts. Sendmail delivers Mails via LMTP to Cyrus and Cyrus puts the mails into the (hopefully) right box. Now I want to replace the Cyrus host with Dovecot. I've searched a bit in Google but there isn't much about LMTP via TCP in combination with DoveCot. Version 2 seems to be get the feature, but we have round about 5k users, so beta is no choice. Also I red something about maidag (mailutils from Gnu) that could do the Job, but maybe there is a better way. I do not want to install Postfix (or any other SMTP service) on that IMAP Server. So I'm asking is there anybody who has the same construct. Important is, that Quota full etc. messages (RFC) gets back to sendmail, so that the MTA reject the mails, before accepting. cu denny

[Dovecot] logging
by James Devine 20 May '10

20 May '10

I am looking through the logging options and wondering if there are a couple of things that we can do 1. Logouts don't seem to show the IP address of the logout, we typically see multiple sessions at a time and wondering if there is a way to tie the logouts to an IP 2. POP logouts show the number of messages retrieved/deleted but I don't see a way to do this with IMAP, is there a logout option for this with imap? Thanks

[Dovecot] looking for IMAP testing tool
by Phil Howard 19 May '10

19 May '10

I'm looking for an IMAP testing tool, suitable to use with Dovecot IMAP. It needs to support TLS, STARTTLS, and login/authentication. It needs to be able run from command line, shell scripts, and even do so under cron jobs (e.g. a way to supply the password to use w/o a terminal prompt). Typical interactive mail clients just don't cut it (even the text mode ones). One reason is I need to do the tests on a number of machines, under a number of user and domain names, and with a variety of parameters or destinations. This is for a suite of regression tests I am putting together intended to verify that configuration changes do not break things (or unbreak things that are supposed to not work). Anyone ever heard of such a tool? Open source would be preferred (better yet, my favorite programming languages: C, Pike, Python).

[Dovecot] problem compiling pigeonhole + my fix

hello, yesterday I tried to package dovecot-2.0beta5 + pigeonhole from Mercurial repository. I put pigeonhole as a subdir in the dovecot sourcetree. Following http://hg.rename-it.nl/dovecot-2.0-pigeonhole/raw-file/tip/INSTALL I called ./autogen.sh; ./configure --with-dovecot=..; make In the buildprocess I saw this output ( from autogen.sh ): Putting files in AC_CONFIG_AUX_DIR, `..'. libtoolize: `config.guess' exists: use `--force' to overwrite libtoolize: `config.sub' exists: use `--force' to overwrite libtoolize: `ltmain.sh' exists: use `--force' to overwrite I dont know *why* AC_CONFIG_AUX_DIR is .. but in .. there are the mentioned files (from dovecot) already present.

We've talked about that before, that the proxy could for instance fall back to itself as the 'final server'. The people in here want to use their existing monitoring script that would do "ssh host doveadm director remove 1.2.3.4". But on top of that, yeah, maybe proxy itself could tell director that some host is down and retry the lookup. Although determining when it's down might not be fully reliable always, so I'm a bit worried that proxy could sometimes fail to connect to a mail server even if it's up (but e.g. with high load, temporary small network problem, etc).

[Dovecot] double write-locking dovecot.index.log
by Mike Abbott 19 May '10

19 May '10

Dovecot's transactions often write-lock dovecot.index.log twice (without unlocking in between), and then unlock it twice. Is that intended, or is that a bug? If I read the man pages correctly, double write-locking is pointless but safe. But double unlocking could cause data corruption during the period between the first and second unlocks, because the locks don't nest (are not refcounted). The first unlock leaves the file totally unlocked. Could this be the source of some index corruption errors? For example: 1. Process A acquires a F_WRLCK on a file. 2. Through a different code path, process A again acquires a F_WRLCK on the same file. Since these locks don't nest this is essentially a no-op. 3. Process A modifies the file. 4. Process A unlocks the file to undo the lock in step 2. Now the file has no lock on it at all. 5a. Process B locks, modifies, and unlocks the file. 5b. Process A also modifies the file, thinking that it still has a write lock. 6. Process A unlocks the file to undo the lock in step 1, but this is another no-op. Data corruption is possible if steps 5a and 5b conflict, or if 5b uses stale data. Here is a code path in dovecot-1.2.11 which exhibits the above behavior. "Outer" write lock: maildir_transaction_save_commit_pre -> maildir_transaction_save_commit_pre_sync -> maildir_sync_index_begin -> mail_index_sync_begin -> mail_index_sync_begin_to -> mail_index_sync_begin_init -> mail_transaction_log_sync_lock -> mail_transaction_log_lock_head -> mail_transaction_log_file_lock -> mail_index_lock_fd -> file_wait_lock -> file_lock_do "Inner" write lock: maildir_transaction_save_commit_pre -> maildir_sync_index_finish -> mail_index_sync_commit -> mail_index_write -> mail_transaction_log_rotate -> mail_transaction_log_file_create -> mail_transaction_log_file_create2 -> mail_transaction_log_file_lock -> mail_index_lock_fd -> file_wait_lock -> file_lock_do The file being locked is the same, dovecot.index.log. In another case, maildir_sync_index_begin is reached this way (outer lock): mailbox_sync -> mailbox_sync_init -> maildir_storage_sync_init -> maildir_sync_context -> maildir_sync_index_begin -> mail_index_sync_begin -> etc. And maildir_sync_index_finish is reached this way (inner lock): mailbox_sync -> mailbox_sync_init -> maildir_storage_sync_init -> maildir_sync_context -> maildir_sync_index_finish -> etc. Could these lead to data corruption? Please let me know if you need any more information. Thanks.

[Dovecot] how authentication works?
by Mihamina Rakotomandimby 18 May '10

18 May '10

Manao ahoana, Hello, Bonjour, I've read: http://wiki.dovecot.org/Authentication/PasswordSchemes I have a users database with clear plain passwords. Dovecot authenticates users without problems against it. Now, it's time to move to CRYPT scheme. Before that, I would like to know how things happen. He have: - the user, (entering his password in the MUA) - the user's MUA (Thunderbird, Outlook, Squirrelmail,...) - the POP or IMAP server - the users database (mySQL) with username and crypt()'d password How I think the process is: - the user enters his password in a clear way. - the MUA sends the password as the user entered it to the POP or IMAP server - the POP or IMAP server fetches the password from the database - the POP or IMAP server crypt()'s the user entered password - the POP or IMAP server compares crypt()'d ones and gives his response Am I close enough to reality? Too far? Misaotra, Thanks, Merci. -- Architecte Informatique chez Blueline/Gulfsat: Administration Systeme, Recherche & Developpement +261 3456 000 19

[Dovecot] %d is empty in mail_location

I have this in dovecot-postfix.conf: mail_location = maildir:/home/mail/dnamesum=%12MLd/dname=%Ld/unamesum=%12MLn/uname=%Ln/mail Yes, it is excessive, but that's just for testing. The pattern I really want is less clear for debugging. In postfix/main.cf I have: mailbox_command = /usr/lib/dovecot/deliver -c /etc/dovecot/dovecot-postfix.conf -a "${RECIPIENT}" I verified through strace that -a "${RECIPIENT}" is in fact getting a full user@domain address. The problem is that %d and %Ld are coming up as empty, and %12MLd is giving me the first 12 hex characters of an md5 of an empty content. It's losing the domain name somewhere. It's in the mail headers and in the -a option. So what else is needed?

[Dovecot] Wiki page(s) to document executable tools?
by William Blunn 14 May '10

14 May '10

Motivated by a desire to know what "doveadm" does: Do we want to be having a page or pages in the Dovecot Wiki which document the executable tools? It might be an idea for each one to say: * What the tool does * How it normally gets invoked (e.g. manually by the administrator, automatically by some other part of Dovecot, automatically by something else) * What parameters it could take and what they would do List of executable tools: (found in Debian dovecot 1.0.15) lib/dovecot/ checkpassword-reply deliver dict dovecot-auth dovecot-config gdbhelper idxview imap imap-login logview managesieve managesieve-login modules pop3 pop3-login rawlog sievec sieved ssl-build-param (found in dovecot 2.0beta5) bin/ doveadm doveconf dsync libexec/dovecot/ anvil auth config dns-client dovecot-lda expire-tool imap-utf7 listview lmtp log maildirlock script ssl-params Regards, Bill

I can also see Dovecot 2.0 builds in there. But they appear to be being made every couple hours, so presumably based on the bleeding edge of the Mercurial repository. It would be kind of handy to have a Debian package of the original 2.0 beta 5 build. Is that lying around anywhere? Regards, Bill

[Dovecot] dovecot 2.0 vs. SELinux
by Michal Hlavinka 14 May '10

14 May '10

Hi, we were modifying old SELinux rules for dovecot 2.0. Everything seems ok, only one report seems odd: "SELinux is preventing /usr/sbin/dovecot "write" access on dovecot.conf." Looking at strace output, dovecot tries to use socket on /etc/dovecot/dovecot.conf which is regular file and no socket: ... geteuid() = 0 getegid() = 0 open("/dev/null", O_WRONLY) = 3 fcntl(3, F_GETFD) = 0 fcntl(3, F_SETFD, FD_CLOEXEC) = 0 socket(PF_FILE, SOCK_STREAM, 0) = 4 fcntl(4, F_GETFL) = 0x2 (flags O_RDWR) fcntl(4, F_SETFL, O_RDWR|O_NONBLOCK) = 0 connect(4, {sa_family=AF_FILE, path="/var/run/dovecot/config"}, 110) = -1 ECONNREFUSED (Connection refused) close(4) = 0 socket(PF_FILE, SOCK_STREAM, 0) = 4 fcntl(4, F_GETFL) = 0x2 (flags O_RDWR) fcntl(4, F_SETFL, O_RDWR|O_NONBLOCK) = 0 connect(4, {sa_family=AF_FILE, path="/etc/dovecot/dovecot.conf"}, 110) = -1 ECONNREFUSED (Connection refused) close(4) = 0 nanosleep({0, 70000000}, NULL) = 0 socket(PF_FILE, SOCK_STREAM, 0) = 4 fcntl(4, F_GETFL) = 0x2 (flags O_RDWR) fcntl(4, F_SETFL, O_RDWR|O_NONBLOCK) = 0 connect(4, {sa_family=AF_FILE, path="/etc/dovecot/dovecot.conf"}, 110) = -1 ECONNREFUSED (Connection refused) close(4) = 0 nanosleep({0, 90000000}, NULL) = 0 socket(PF_FILE, SOCK_STREAM, 0) = 4 fcntl(4, F_GETFL) = 0x2 (flags O_RDWR) fcntl(4, F_SETFL, O_RDWR|O_NONBLOCK) = 0 connect(4, {sa_family=AF_FILE, path="/etc/dovecot/dovecot.conf"}, 110) = -1 ECONNREFUSED (Connection refused) close(4) = 0 nanosleep({0, 80000000}, NULL) = 0 ... (tries to connect 14x) traceback for connect causing this selinux denial is: connect net_connect_unix : lib/network.c #246 net_connect_unix_with_retries : lib/network.c : #255 master_service_open_config : lib-master/master-service-settings.c #157 master_service_settings_read : lib-master/master-service-settings.c #302 master_settings_read : master/main.c main : master/main.c Does anyone know what happens here? Why dovecot tries to use regular file dovecot.conf as socket? There is probably some magic in it (from my pov) which I don't understand. Regards, Michal Hlavinka

hi, I am currently experiencing a problem: there is a group of 200 people to this group when a user send a large message (50MB), can easily lead to congestion. Is there a good way to handle such a situation, like the hard link cyrus?

[Dovecot] Compressed mail archives
by Will Palmer 14 May '10

14 May '10

Hello, I have recently begun using IMAP to access my mails, and have found that the size of my maildir is quickly getting larger than I had anticipated. Googling around, I've seen a lot of messages related to compressing individual messages in a maildir. However, what I'm really looking for is a solution which will allow multiple messages to be compressed into a single compressed file, while still allowing those messages to be accessed via IMAP. The reasoning behind this is that most of my incoming mail consists of many very-similar messages (for example, it is not unheard of for me to receive 10,000 emails detailing the same error report over a weekend, with the actual "needs to be processed" parts stuck on the end of each message) I'm expecting a simple "no, there's no way to do that", but I wouldn't mind being pleasantly surprised. My question again: Is there any way to keep a bundle of older mails compressed, so that they can enjoy the high compression of being very similar to each-other, while still allowing access via imap? A solution may involve (just throwing out ideas here, which I have no idea how to implement) putting messages older than N days into an MBox file, and either somehow linking my account to that file (so that my account consists of [compressed readonly Mbox]+[live uncompressed Maildir]), or perhaps the first half of that, but accessing archived messages through a separate account. (Not the preferred way, but if it's the only way, I'll do it) But really I don't even know if it's possible to have dovecot support MBox and Maildir simultaneously, nor do I know enough about the MBox format to even know if the IMAP-style "multiple mailboxes" thing is possible in MBox. Please excuse my no-doubt confused terminology and general air of doesn't-know-what-he's-talking-about. The internals of e-mail are generally not my thing, so I'd appreciate any pointing in the right direction which anyone may have to offer. Any ideas?

[Dovecot] Can't get Thunderbird 2 to delete a folder under mdbox (Dovecot 2.0beta5)
by William Blunn 13 May '10

13 May '10

Can't get Thunderbird 2 to delete a folder under mdbox (Dovecot 2.0beta5) I have built Dovecot 2.0 and installed it under "/opt/dovecot2". I have done the minimum configurations necesary to get it to work with SSL, systems users but with a secondary password database, and set up mail location as "mdbox:~/dbox". I had to create the directory "dbox" in the user's home directory to get things working. Using Thunderbird 2, I can happily copy messages into this system and read them out again, and that all works. In the user's "~/dbox" directory, I get a "storage" directory and a file "m.1". I can also create folders, and nested folders, and put messages into those and read them out again, and that all works. If I try to delete a folder through Thunderbird 2, what happen is that the folder gets moved to be under a folder "Trash" (which Thunderbird calls "Deleted"). So if I had a folder "foo" and deleted it, I end up with a folder "Trash/foo" (which Thunderbird calls "Deleted/foo"). Fair enough: Thunderbird is doing a trash can model on folders. I then go to remove the folder foo from "Trash". Thunderbird doesn't complain, and the folder disappears from the folder list. But upon re-starting Thunderbird, we see that the folder "foo" is still there under "Trash". So it seems the folder was never properly deleted. Perhaps this is a bug in Thunderbird 2, but since this is a beta Dovecot with a new storage subsystem, I thought I would suggest that it might be an issue with Dovecot 2.0beta5. Regards, Bill

[Dovecot] antispam plugin problem

Hi I have installed a plug-in an antispam and when I try to move the message to a folder a spam mutt produces an error "Failed to call dspam."

[Dovecot] Dovecot and POP3
by DJ GRP 13 May '10

13 May '10

Hi all, I run Dovecot 1.2.9, for both IMAP and POP3 access. I was wondering if there is a way to force messages be deleted from server when the user uses POP3, even if she has selected a 'Leave messages on server' option. I was able to do it in the past using Qpopper (--enable-auto-delete option). Thanks

[Dovecot] auth: Error: PLAIN(user): Request 27511.1 timeouted after 150 secs, state=3
by Mark Sapiro 13 May '10

13 May '10

Since upgrading from Dovecot 2.0.beta4 + patches http://hg.dovecot.org/dovecot-2.0/rev/96496e1d3d12 and http://hg.dovecot.org/dovecot-2.0/rev/aefa279e2c70 to Dovecot 2.0.beta 5, I have started to see the subject error from Dovecot for SASL authentications. It doesn't happen every time, but it happens more often than not. It doesn't seem to affect Postfix's acceptance of the message. One other change made about the same time as the dovecot upgrade that may be involved is the addition of smtpd_sasl_authenticated_header = yes in Postfix.

[Dovecot] Help with acl_shared_dict
by Marcio Merlone 11 May '10

11 May '10

Hi all, I am trying to set up shared folders with dovecot 1.2.10-0xk1 on a ubuntu 8.04 server and so far so good. I managed to share a folder using GOSa GUI, but I cannot list it on Thunderbird yet, because of acl_shared_dict param (I guess). I tried BDB as per the wiki: plugin { acl_shared_dict = file:/var/lib/dovecot/shared-mailboxes.db } I gave shared-mailboxes.db 0666 perms but it keeps resetting permissions to 0600, which gives me "open(/var/lib/dovecot/shared-mailboxes.db) failed: Permission denied" errors. So I went to try sql dict, but could not find where to put sql server connection details like user, host, password. dovecot -n (with sql dict): # 1.2.10: /etc/dovecot/dovecot.conf # OS: Linux 2.6.24-27-server i686 Ubuntu 8.04.4 LTS log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps managesieve ssl_cert_file: /etc/ssl/certs/dovecot.pem ssl_key_file: /etc/ssl/private/dovecot.pem disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(managesieve): /usr/lib/dovecot/managesieve-login mail_privileged_group: mail mail_location: maildir:~/Maildir mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(managesieve): /usr/lib/dovecot/managesieve mail_plugins(default): quota imap_quota acl imap_acl mail_plugins(imap): quota imap_quota acl imap_acl mail_plugins(managesieve): mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(managesieve): /usr/lib/dovecot/modules/managesieve namespace: type: private separator: / inbox: yes list: yes subscriptions: yes namespace: type: shared separator: / prefix: shared/%%u/ location: maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u list: children lda: postmaster_address: postmaster(a)a1.ind.br hostname: a1.ind.br mail_plugins: quota sieve acl auth default: mechanisms: plain login passdb: driver: pam args: session=yes blocking=yes dovecot userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/dovecot mode: 436 user: postfix group: postfix plugin: quota: maildir:storage=10485760 acl: vfile acl_anyone: allow acl_shared_dict: proxy::acl dict: acl: mysql:/etc/dovecot-dict-sql.conf (/etc/dovecot-dict-sql.conf is a copy from the wiki) Have I missed something?

[Dovecot] Best location for indexes?
by Brandon Lamb 11 May '10

11 May '10

I cant seem to find anything via a google search, so if this has been answered I apologize. I am wondering if INDEX=MEMORY is going to give the best performance versus files? I have a server with directly attached storage, 8 gigs of ram, about 500 gigs of data. I am ok with losing and having to rebuild the indexes on a reboot as the last uptime was over 200 days

[Dovecot] Client cant see emails

Hello, Last Saturday i scp the vmail folder from server1 running SLES to server2 running Debian.

[Dovecot] Reading emails, vmail user mail access problems.
by David Haggard 11 May '10

11 May '10

Hello, I have a new installation of Ubuntu 10.04 64bit and all packages are from the Ubuntu repos. dovecot version 1.2.9 My goal is to have a basic email server setup with imap and pop support so imap users can send and receive email for the company. Setup: I have a few users that will be using this mail server so I do not need anything advanced and I am ok with creating a user account with a password and managing email addresses manually. I currently have system accounts for a test user and I have setup virtual mailbox as this mail server will host 2+ domains. Postfix is installed and running, I also confirmed mail flow to this box and from this box is working to the test user created. I can log in with the test username of the system and this is the point at which I have some issues as I am having a permission problem which I think is related to dovecot. What I am not able to do is download emails via imap client, but I can send emails just fine. If I change the permissions of the virtual mailbox to the test user that is logged in to chmod 777 I can download emails, but I can't do this for each new email to that users mailbox. /var/vmail/DOMAIN/USER1/cur/ and anything listed here will be owned by vmail so no other user can read it. (can't download emails) as dovecot seems to be trying to use USER1 as a user to read the files. How can I have dovecot read emails as vmail no matter what user logs in? I have tried many config changes using vmail but its failed so I need some advise. Here is my config: I edited the DOMAIN to hide the real domain used. # 1.2.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-21-server x86_64 Ubuntu 10.04 LTS ext4 log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login mail_location: maildir:/var/vmail/DOMAIN/%n/ mbox_write_locks: fcntl dotlock mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 auth default: passdb: driver: pam userdb: driver: passwd userdb: driver: static args: uid=vmail gid=vmail home=/var/vmail/DOMAIN/%n/ Thank you

[Dovecot] wrong config file?
by Phil Howard 10 May '10

10 May '10

The sample provided config file (the one I started with by editing it) included the following text: # ------------------------------ WARNING ------------------------------- > > # If there's a file /etc/dovecot/dovecot-postfix.conf, which is part of > # dovecot-postfix package, it will be used instead of dovecot.conf. > > # Keep in mind that, if that file exist, none of the changes in > # /etc/dovecot/dovecot.conf will have effect on dovecot's configuration. > # In that case you should customize /etc/dovecot/dovecot-postfix.conf. > > # ------------------------------ WARNING ------------------------------- > So I expected it would use that by default. It seems to not be doing so. Does this mean I have to modify the startup scripts to add the -c option to force the use of this config file? Or should I just put all my configs in the default "/etc/dovecot/dovecot.conf" file? When doing "dovecot -n" it became apparent that my configs were not being used. But "dovecot -c /etc/dovecot/dovecot-postfix.conf -n" was doing it. Any idea why it's not behaving as those comments described?

[Dovecot] configuration user= or auth_user=
by Phil Howard 10 May '10

10 May '10

The sample config file has: # User to use for the process. This user needs access to only user and # password databases, nothing else. Only shadow and pam authentication # requires roots, so use something else if possible. Note that passwd # authentication with BSDs internally accesses shadow files, which also # requires roots. Note that this user is NOT used to access mails. # That user is specified by userdb above. user = root # Directory where to chroot the process. Most authentication backends don't # work if this is set, and there's no point chrooting if auth_user is root. # Note that valid_chroot_dirs isn't needed to use this setting. #chroot = So is the variable for the authentication process user supposed to be "user" or "auth_user"? It would make more sense to be "auth_user". Is it just "user" for legacy reasons, and the reference to "auth_user" is in error? Or can either name be used? Also, those of you who change this, do you change it to something existing like "dovecot" or "vmail" or "nobody" or do you make a whole new user for it?

10 May '10

Hi All, I am new to dovecot so this may be a very easy thing to do. I need to setup a postfix+dovecot server for a multilocation setup The rules are very simple mails to *(a)local.example.com send to dovecot mails to *(a)otherlocation.example.com send to smtp:[otherlocation] But the users are created on dovecot as user(a)example.com. How can I configure dovecot to accept mails for *(a)local.example.com and deliver to *(a)example.com I use lmtp_generic_maps for a similar thing in postfix+cyrus Thanks Derwyn.

[Dovecot] problems implementing dovecot LDA with Postfix
by Stan Hoeppner 09 May '10

09 May '10

Per the instructions here http://wiki.dovecot.org/LDA and here http://wiki.dovecot.org/LDA/Postfix I set postmaster_address = postmaster(a)hardwarefreak.com in /etc/dovecot/dovecot.conf and mailbox_command = /usr/lib/dovecot/deliver in /etc/postfix/main.cf When I restart dovecot I get this: [07:17:00][root@greer]/etc/dovecot$ /etc/init.d/dovecot restart Restarting IMAP/POP3 mail server: dovecotError: Error in configuration file /etc/dovecot/dovecot.conf line 754: Unknown setting: postmaster_address Fatal: Invalid configuration in /etc/dovecot/dovecot.conf failed! And after restarting Postfix and sending a test message from a gmail account I get this in the mail log: May 9 07:26:09 greer postfix/qmgr[13384]: AEE976C32C: from=<snugmonster(a)gmail.com>, size=1628, nrcpt=1 (queue active) May 9 07:26:09 greer dovecot: deliver(stan): Fatal: postmaster_address setting not given May 9 07:26:09 greer postfix/local[13392]: AEE976C32C: to=<stan(a)hardwarefreak.com>, relay=local, delay=1.4, delays=1.3/0.03/0/0.04, dsn=4.3.0, status=deferred (temporary failure) The server is Debian Lenny 5.0.4 with Postfix 2.5.5 and Dovecot 1.2.11 from Lenny backports. Any ideas? Everything I've found via Google relating to this Dovecot startup error has to do with people converting old dovecot.conf files to a new dovecot version. -- Stan

[Dovecot] CRYPT scheme and 8 character limit
by Phil Howard 09 May '10

09 May '10

I've decided that having users supply cleartext passwords for me to encrypt and encode is a bad idea, anyway. So maybe I won't need dovecotpw. The idea is that users supply an already-encrypted password. Most of the users can fetch their login password from /etc/shadow on their own computer. Wiki page http://wiki.dovecot.org/Authentication/PasswordSchemes indicates that scheme name CRYPT is the one that uses the libc crypt() function. But it also says it uses no more than 8 characters. Then there is MD5-CRYPT. But that doesn't call crypt(), I presume. No limit on password size is indicated. But this at least looks like SOME of the encrypted passwords I have. Other passwords I have have ids indicating SHA-256 and SHA-512. Here is an example from /etc/shadow that encrypted the clear password "dovecotandpostfix" (in case it is necessary to test it): $6$IwZzpjjj$p1VrkxQmgmTED8iQnQrV3sVEZpBmw2N8oD1ykOguXB5tf8aahICesX0TF6.VMThIW2QFs1buHjT3eDtnaAFhF1 The big question is, what scheme name should I use for these passwords? I can, of course, consider the id (6 in the above example, suggesting SHA-512) if there is one (so far all are like this). But the other consideration is most of the passwords are longer than 8, some longer than 12, characters. So apparently CRYPT can't be used in those cases (so I can't have the automatic identification of crypt() to detect the scheme). What scheme would I use for the various passwords? What scheme would be used for the above example for starters? What if the id is 5 or 1 (the ones documented for the crypt() call)?

[Dovecot] looking for feedbacks on courier to dovecot
by Mihamina Rakotomandimby 08 May '10

Manao ahoana, Hello, Bonjour, We currently run courier POP . We would like to switch to Dovecot. I encounter problems when migrating the UIDL because we have big Maildirs and POP re-downlading the data is not possible for most of the users. I tried the http://www.dovecot.org/tools/courier-dovecot-migrate.pl script but I still have the re-downloading event. What are your stories and advices about courier-to-dovecot move?

[Dovecot] Questions, Issues with 2.0
by Kelsey Cummings 08 May '10

08 May '10

I'm trying to use an external program to set the location of user's maildirs to match an existing hashing schema but the docs for how to do this in 1.x do not seem to apply to 2.0 or I'm misinterpreting them. protocol imap { mail_executable = /opt/dovecot-test/sonic-imap ... This correctly executes the and attempts to sets the MAIL variable but it appears that mail_executable is run before the user is logged in so the $USER variable isn't set and the process' uid is still 0. We also need to have dovecot include an additional maildir for each user that is currently stored outside of the user's main maildir directory into the same namespace as a specific folder name. Is there a way to do this in dovecot directly or will it need to be hacked (as it is currently with courier) or could it be done with a plugin? I've also noticed that while doveconf complains about mail_executable: May 3 13:44:10 a dovecot: config: Obsolete setting in /opt/dovecot-test/etc/dovecot/conf.d/imap.conf:7: mail_executable has been replaced by service { executable } However, when replaced as suggested by doveconf: protocol_imap { executable = /opt/dovecot-test/sonic-imap ... It fails altogether: doveconf: Fatal: Error in configuration file /opt/dovecot-test/etc/dovecot/conf.d/imap.conf line 7: Unknown setting: executable Similarly, it also suggests 'drop_priv_before_exec = no' which doesn't appear to be valid either. -- Kelsey Cummings - kgc(a)corp.sonic.net sonic.net, inc.

[Dovecot] Requiring STARTTLS only on some networks

Hello Timo, is there a way, either in 1.2.x or in 2.x to activate disable_plaintext_auth=yes only for some address or network ? The idea would be to enable clients from the internal networks to keep making clear text connections while forbidding it to the rest of the world.

[Dovecot] Tracing sieve execution
by Jerry 07 May '10

07 May '10

I have just recently begun learning how to use sieve. For the most part, it works fine. The problem is that I have created some rather complicated rules. Occasionally, an e-mail will get sorted incorrectly and I am not able to easily determine what rule caused it to occur. Is there any way or utility that I could use to actually see what rule or line in the sieve file caused the action? -- Jerry Dovecot.user(a)seibercom.net Disclaimer: off-list followups get on-list replies or get ignored.

[Dovecot] ACLs and public folders
by hyperbatus＠gmx.de 07 May '10

07 May '10

Dear list, I am using dovecot 1.0.15 on Debian Lenny. I have a public folder, I use ACL / vfile (without public ACL), and I use maildir / vmail. Now I have two questions: 1) http://wiki.dovecot.org/ACL states: "Mailboxes in public namespaces don't have owners, so by default no-one can access them." The same document, when explaining the meaning of the k flag in the ACLs, states: "Mailboxes can be created (or renamed) under this mailbox (there is no recursion, so creating a mailbox under this mailbox's child uses only the child's ACLs)" I have placed an ACL (dovecot-ACL) at the root of the public namespace (all rights to anyone). The public namespace was appearing correctly in my IMAP client. Then I have copied a large folder with hundreds of nested subfolders (nesting level > 3) from another account to the root of the public namespace. According to the documentation mentioned above, this should not have been possible (if I got the docs right): The first nesting level of folder should have been created, but not the messages in them and for sure not the deeper nested folders. There is no dovecot-acl within a single of the first level folders (I have verified this), so no one should have access to them. Nevertheless, in addition to the succesful copy, I can see every folder and every message in my IMAP client, I can delete and so on. Could some please explain if I got the docs wrong? 2) If there really is no ACL recursion, how are we supposed to copy large folder structures (perhaps thousands of folders, nested to 5 levels deep) to a public namespace? Do we need to create all folders by hand, then place the dovecot-acl in each folder, and then copy the messages to each folder by hand? Do we need to switch to global ACLs so that we can establish a master user for doing the act of filling the public space? Or is there a dovecot module which, immediately after creating a folder, looks into the parent folder of the new folder and copies the dovecot-acl from the parent folder to the new folder? Currently, I am very happy that dovecot didn't what it should do according to my understanding of the documentation (since I really needed to copy this folder structure to the public namespace), but on the other hand, I am a bit puzzled now not knowing if the documentation is wrong, my understanding of it is wrong or the source code is wrong :-) Thanks you very much for any help, Peter Here is the output of dovecot -n: # 1.0.15: /etc/dovecot/dovecot.conf base_dir: /var/run/dovecot/ log_path: /var/log/dovecot.log info_log_path: /var/log/dovecot-info.log log_timestamp: %Y-%m-%d %H:%M:%S protocols: imaps listen: 192.168.20.23 ssl_cert_file: /etc/dovecot/imap-ssl.home.omeganet.de.crt ssl_key_file: /etc/dovecot/imap-ssl.home.omeganet.de.key ssl_parameters_regenerate: 24 ssl_cipher_list: ALL:!LOW login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login login_processes_count: 1 login_max_processes_count: 32 max_mail_processes: 32 mail_privileged_group: mail mail_location: maildir:~/Maildir mail_cache_fields: mail_never_cache_fields: mail_plugins: acl namespace: type: private inbox: yes namespace: type: public prefix: Archive. location: maildir:/home/vmail/archive:INDEX=~/Maildir/archive auth default: cache_size: 1 cache_ttl: 600 worker_max_count: 4 passdb: driver: passwd-file args: /etc/dovecot/passdb userdb: driver: static args: uid=vmail gid=vmail home=/home/vmail/%u socket: type: listen master: path: /var/run/dovecot/auth-master mode: 384 user: root plugin: acl: vfile -- GMX DSL: Internet, Telefon und Entertainment für nur 19,99 EUR/mtl.! http://portal.gmx.net/de/go/dsl02

[Dovecot] disable plaintext auth ... only for some addresses
by Phil Howard 06 May '10

06 May '10

I'd like to disable plaintext authentication (e.g. only allow authentication that does STARTTLS or connects on SSL/TLS only ports) only for certain (most) IP addresses. I want to exempt a few addresses (users coming over known VPNs). Fortunately, all this is coming in over a firewall (Sonicwall) in which I can NAT traffic by IP address to go to specific port numbers. So, if I can establish a different disable_plaintext_auth policy by port number (for extra port numbers I'll choose later), that would let me accomplish this. If I cannot do this, then my only alternative is making the SSL/TLS only ports the only ones open to the internet, and use the non-SSL/TLS ports only for the VPNs (with disable_plaintext_auth = no). But I read somewhere that this is discouraged. What say ye?

[Dovecot] adding users to passwd-file
by Phil Howard 06 May '10

Is there a tool equivalent to the system "passwd" command (or maybe "adduser" or "useradd") that can support a passwd-file by setting a password, encrypting it with the salted MD5 scheme? The system "passwd" command doesn't have an option to "do it to this alternate file instead of /etc/shadow".

The socket is set up so that deliver should be able to talk to the db, but I'm not seeing anything in the expires table when I look. Is there anywhere that expire can log to so I can see what might be happening? It doesn't look like it logs to the dovecot log.

[Dovecot] [Bug] Case sensitive usernames and variables
by Неворотин Вадим 05 May '10

05 May '10

Today I've found a very irritating bug: I use mail_location = maildir:/var/mail/%u/ in my dovecot.conf. And if user type Username, username, USERname etc at login dovecot create a different Maildir's for one real user. But LDA works corretly and save all messages to lowercase username mailbox. No problem, add L: mail_location = maildir:/var/mail/%Lu/ Then all works good. But I has also such namespace configuration: namespace shared { separator = / prefix = &BCAEMARBBEEESwQ7BDoEOA-/%%u/ location = maildir:/var/mail/%%u:INDEX=/var/mail/%u/shared/%%u subscriptions = no list = children } And here I can't replace %u with %Lu, because dovecot write to dovecot.log: IMAP(malamut): Error: Namespace '&BCAEMARBBEEESwQ7BDoEOA-/%Lu/': shared: Shared namespace prefix contains unknown variables So user has only one mailbox (with lovercase name), but a lot of different indexes for shared mailboxes, eg /var/mail/username/shared, /var/mail/USERname/shared etc. How can I tune dovecot to use always lowercase username?

[Dovecot] Access filesystem (NFS) as some user
by Mihamina Rakotomandimby 05 May '10

05 May '10

Manao ahoana, Hello, Bonjour, My Dovecot server has to access the users Maildirs. Maildirs are on a NFS mount that only a user (vmail/500) may read and write. No one else. How to configure Dovecot so that at least disk read-write are performed as a "vmail" user (that I have created with the right attributes)? Is the workaround of changing dovecot's system UID/GID a not-so-bad one? (I am trying to see if it works, at least...) Misaotra, Thanks, Merci. -- Architecte Informatique chez Blueline/Gulfsat: Administration Systeme, Recherche & Developpement +261 34 29 155 34 / +261 33 11 207 36

[Dovecot] Dovecot antispam plugin with virtual users
by Philipp 04 May '10

04 May '10

Hi, I'm running dovecot 1.2.11 with the antispam plugin 1.2+20090702-1+b1 installed from the debian repos (squeeze) and dspam 3.9.0+git20100416-1. Unfortunately this doesn't seem to work well with my virtual users, stored on a local openldap server: While sending mail manually to dspam does work, there's some trouble when trying to use the antispam plugin. I tried using both sendmail (exim4 in my case) and configuring antispam_mail_sendmail = /usr/bin/dspam to point to dspam, with similar results: exim: [15042] Failed to get user name for uid 5001 dspam: dspam[18961]: Unable to determine the runtime user both errors are reproducible by running exim/dspam with sudo -u \#5001 with 5001 being the virtual uid used of the user that is logged in through imap. Of course the uid 5001 is invalid for the rest of the system, so it can't run anything, but as far as I can tell the plugin uses this uid to call the respective programs :\ Now I was wondering if it was possible to keep the plugin from using the imap-uid and instead specifying one elsewhere? I guess this would be of fairly great interest for everyone using virtual users, be it ldap or anything else. Or is there a different way to do this? Do I maybe just miss setting a variable somewhere? Philipp

[Dovecot] dovecot user
by Timo Sirainen 04 May '10

04 May '10

Any thoughts on this: The primary use for "dovecot" user has been for login processes. But people keep misunderstanding this and try to use dovecot for accessing mails. For years I've been wondering about renaming this user to something else like dovelogin, but it never really seemed practical. So now with v2.0 there are a bunch of new processes, and for example anvil and dict are now run as dovecot user by default. But it's not really good that login processes can just go and kill those processes. And even worse, if drop_priv_before_exec=yes they could ptrace these processes. So I think we need two Dovecot users for v2.0: 1. Completely untrusted user for login processes. 2. Slightly more trusted internal Dovecot user. So "dovecot" could be reused for 2. And it would no longer be a mortal sin to use dovecot user for owning mail files. For 1. there would be a new user. I'd use "dovelogin", but apparently tools still don't much like usernames that are longer than 8 characters. Like ps could show numeric uid instead of 9 character long username. So .. any suggestions? "dovlogin" could be one possibility I guess. It would be nice if the name somehow reminded of login processes, but maybe something else could be used too, like: dovenil, dovenull, dovezero, dovenone, dovevoid, doveint, dovedown, dovein, dove0

[Dovecot] Dovecot SQL user_query
by Alex 04 May '10

04 May '10

Hello folkz, Is it possible to setup in dovecot-sql.conf file to run user_query twice if its first run didn't yield any values. And likewise don't proceed with the second run if the first user_query execution produced the result. I have to query two tables which specify there email messages shall be delivered via Dovecot deliver LDA depending on the incoming email addresses. Please don't question me about this setup. I inherited this mess from the previous Network Admin. First query should be ran like this: user_query = SELECT concat('maildir:/data/mail/',maildir) as mail FROM folders WHERE email = '%u' If the first query doesn't yield any result the second shall be ran like this: user_query = SELECT maildir as home FROM users WHERE email = '%u' Please advise if such user_query setup is possible at all. Thanks in advance, Alex

[Dovecot] exit codes for 'sievec'
by Jerry 03 May '10

03 May '10

As far as I can tell, 'sievec' always exits with '0' whether there is an error or not. If that is correct, I believe it should be modified to exit with some other code if the conversion and writing of the new file are not completed successfully. I have written a few script files and a 'make' file specifically for sievec. The inability to get an accurate exit code is problematic for me. -- Jerry Dovecot.user(a)seibercom.net Disclaimer: off-list followups get on-list replies or get ignored.

[Dovecot] [SUGGESTION] Managesieve: Transparent home dir creation
by Felix Leimbach 03 May '10

03 May '10

Hi all, I'm using dovecot 2.0-beta4's sieve plugin and it works great but here is an idea for improvement: When creating the first sieve script for an account whose home dir does not yet exist then dovecot *does* create that homedir but the sieve client times out. Tried Thunderbird's sieve addon as well as horde's ingo. The log says: dovecot: managesieve-login: Login: user=<me(a)example.com>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured dovecot: managesieve(me(a)example.com): sieve-storage: sieve_storage_verify_dir(/mnt/data/vmail/dovecot-homedirs/example.com/me//s… failed: File exists dovecot: managesieve(me(a)example.com): Fatal: Failed to open Sieve storage. Because the homedir was created (great!) when I retry the same action then all works perfectly well. So why not make that homedir creation transparent so that the clients' first try succeeds instead of the second try? Cheers, Felix

[Dovecot] What causes dovecot to rebuild dovecot-uidlist?
by Pat 02 May '10

02 May '10

Hello, In what situations will Dovecot 1.2.11 rebuild its uidlist? I am using the maildir storage format, and I am also modifying the uidlist manually (so it's possible I could jack* things up). I have found some related code in maildir-uidlist.c: maildir_uidlist_next. 1) Blank filename or UID 0 2) Any UID not being greater than the proceeding UID 3) Any UID being greater than ~4 billion. 4) Any UID being greater than the suggested next uid. 6) If a filename contains a / 7) General header line sanity checking. Are there any other sections of the code that do sanity checks on dovecot-uidlist (for Maildir type storage)? And optionally do you agree that maildir_uidlist_set_corrupted is the best place to watch to see if I have mangled the uidlist? Thanks in advance, Pat * I insert into dovecot-uidlist manually when I deliver new messages, or discover a message that is not in uidlist for some reason. For compatability reasons I maintain a completely separate cache. If there is a better way to keep the uidlist up to date when the user isn't necessarily accessing the account via dovecot imap, I'm open to suggestions. However my situation is fairly unique I think.

[Dovecot] UK Blackberry BIS and Dovecot - 2-way sync
by Lucio Godoy 01 May '10

Hi All; I have search the net and i cannot find any answers or fixes for this issue. I have a RHEL5 server running Dovecot Version 1.2.11 all worked well until i have diceded to subscribe to Vodafone's BIS service (BB Bold 9700). Internally I use outlook, and it does 2-way sync without any issues, but the blackberry only syncs new email and it does not sync deleted emails when I delete them in Outlook. Is there any special setting to allow such synchronisation? My server is secured by a pix firewall with ports 993, and 995 open for email sync (Secure IMAP and Secure Pop), i have setup the blackberry to use port 993. Many thanks for your help.

Sometimes dovecot leaves errormessage in Log: IMAP(username): FETCH [HEADER] for mailbox INBOX UID 5106 got too little data (copying): 516 vs 528 Until now only Inbox was effected and no other folders. I delete cachesfiles in ~mail/.imap to solve this but is there a way to do this automatical (self healing)? Dovecot could recreate complete caches if there was a difference in calculation.

[Dovecot] Quota maildirsize and dbox
by luben karavelov 30 Apr '10

30 Apr '10

Hello, Is there any reason that maildirsize Quota store should not work in dbox folders or any other folder based mailbox stores? I have patched a test version here and it seems to work (added "dbox" check in src/plugins/quota/quota-maildir.c line 785). If there could be any complications or unexpected consequences of this setup? Thanks in advance luben

[Dovecot] Expire plugin / expire-tool redesign for doveadm
by Timo Sirainen 30 Apr '10

30 Apr '10

Expire plugin / expire-tool seems annoyingly inflexible currently, so I was thinking about a more generic redesign: The expire plugin keeps track of the oldest message in configured mailboxes. Its only configuration is the list of tracked mailboxes. There's no configuration like what the expire timeouts are or anything. There will be a new doveadm command: doveadm expunge [-u user | -A] <mailbox> <search query> So when you want to expunge all mails from Trash older than 1 week for all users, you say: doveadm expunge -A Trash savedbefore 1w This command works even without expire plugin. To optimize it to avoid looking into all users' Trash mailbox, there's a new expire doveadm plugin, which can use the expire dict to filter out users who don't have anything to expunge. This also supports another feature that the plugin can optimize: doveadm move -A INBOX Archive/2009/INBOX since 2009-01-01 before 2010-01-01 And since people have had problems waiting for expire dict to fill, there could be also a new parameter that does the filling immediately. TODO: - dbox altmove feature will be removed from expire plugin. it may need another plugin, or some other way to configure expire plugin for it. it's anyway a special case. - When using multiple mailboxes it would be more optimal to handle all mailboxes for a user at once, rather than using separate doveadm commands. Maybe the command syntax needs some more thinking to support this. Different mailboxes could have different rules though..

[Dovecot] Released Pigeonhole Sieve v0.1.16 for Dovecot v1.2.11
by Stephan Bosch 30 Apr '10

30 Apr '10

Hello Dovecot users, Pigeonhole development has slowed down significantly in the last few months due to the fact that I got swamped in work. The plan is now to move active development of Pigeonhole to Dovecot v2.0, meaning that this will be the last release for v1.2 that contains significant development changes and new features. However, if a certain new feature is simple enough and there is a demand for it, I may backport it from v2.0 and release it along with any bugfixes that may still arise. The main thing that this new release adds is full support for the spamtest, spamtestplus and virustest extensions. These extensions implement a uniform means of testing the content spam/virus status headers in mail messages: http://ietfreport.isoc.org/idref/rfc5235/ Not many people have tested these new features yet and therefore these are currently considered experimental. Test these thoroughly before you start using them! Documentation is available in doc/spamtest-virustest.txt Changelog Sieve v0.1.16: * Finished implementation of spamtest, spamtestplus and virustest extensions. These are not enabled by default and need to be activated with the sieve_extensions setting. Documentation available in doc/spamtest-virustest.txt + Vacation extension: the from address of the generated reply is now by default equal to whatever known recipient alias matched the headers of the message. If it is one of the aliases specified with :addresses, it is used in stead of the envelope recipient address that was used before. + Restructured and optimized the lexical scanner. + Added --with-docs configure option to allow disabling installation of documentation. - Accidentally omitted 'extern' in two declarations of global variables in header files, causing compile failures on certain systems. - Deprecated imapflags extension: fixed implicit assignment of flags. Turns out this never really worked, but the effect of this bug was obscured by the removeflag bug fixed in the previous release. - Fixed various memset argument mixups in enotify extension. This caused warnings on certain systems, but luckily no adverse effects at runtime. The releases are available as follows: Sieve: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.16.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.16.tar.gz.sig Refer to http://pigeonhole.dovecot.org for more information. Have fun testing the new releases and don't hesitate to notify me when there are problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

[Dovecot] Again: Occasional problem with POP3-Download
by Andre Tann 30 Apr '10

30 Apr '10

Hello everyone, in february I posted the mail below[1]. I can now reproduce the problem. When filling up a mailbox with postfix' smtp-source with dozens of identical mails, then it is never possible for me to fetch one single mail out of the mailbox. The process of fetching mail via POP3 always fails. It makes no difference which mail client I use. I have tested KMail, Outlook and Thunderbird. Can anyone confirm this? Is dovecot for some reason unable to deliver such identical mails? Can it be the case that this is a problem with too similar message ids? ~/Maildir/cur$ cat * | grep -i message-id Message-Id: <1024.0003.0008@alphamobil> Message-Id: <1024.0003.0009@alphamobil> Message-Id: <1024.0003.0006@alphamobil> Message-Id: <1024.0003.0007@alphamobil> Message-Id: <1024.0003.0005@alphamobil> Message-Id: <1024.0003.0004@alphamobil> Message-Id: <1024.0003.0003@alphamobil> Message-Id: <1024.0003.0002@alphamobil> Message-Id: <1024.0003.0001@alphamobil> Message-Id: <1024.0003.0000@alphamobil> Thanks and greetings from Munich! AT [1] Hello everyone, I have two mailservers [1] running dovecot. Mail store format is maildir. Every once in a while I have the following problem: When a User downloads his mail via POP3, the client says something like "the server has closed the connection unexpectedly, and gives this reason: [...blahblah...]". One can now cancel the download, and restart it, and the problem shows up again and again. The first few mails get downloaded, and then the process stops. Strange to say the "blahblah"-portion is a piece of text out of the email that doesn't want to get downloaded. Then I remove this single message out of the Maildir/cur-directory, and everything is fine again. It is easy to figure out which mail to delete because it's the first one that is not market as seen [...] filename...:2,S otherfilename...;2, <= this file must be deleted [...] For me it looks as if dovecot had a problem with some byte sequence in this mail, and for some reason it gives an error message to the client which is taken out of the mail. On the SuSE-Machine, before dovecot there was a courier-imapd running, which never showed this kind of problem, so it should not be a client problem. Hopefully my description is clear enough. Does anyone have an idea what's going on here? Thanks. Andre [1] One machine is a openSuSE 11.2 with # rpm -qa | grep dovecot dovecot12-backend-sqlite-1.2.9-0.1.1.i586 dovecot12-backend-mysql-1.2.9-0.1.1.i586 dovecot12-backend-pgsql-1.2.9-0.1.1.i586 dovecot12-1.2.9-0.1.1.i586 The other machine is a Debian Lenny with # dpkg -l | grep dovecot dovecot-common 1:1.0.15-2.3+lenny1 dovecot-imapd 1:1.0.15-2.3+lenny1 dovecot-pop3d 1:1.0.15-2.3+lenny1 -- Andre Tann

[Dovecot] Question about auth multiple configuration
by Fabrice MATHIEU 30 Apr '10

30 Apr '10

Hello, My mail system is build with postfix, dovecot and roundcube. In first time users can view and "manage" their mail only on the webmail. So this one (webmail) use IMAP (no tls/ssl at all) authentication to give access to users maildir. This connection is made on the 'loopback' interface and use PLAIN method. This works fine (configuration below without ssl parameters). Now I want to see and send my mail with a MUA (thunderbird). As my system is on an Internet provider I want to add more security "solutions". I use smtps with postfix and SASL/auth by dovecot socket mechanism to send mail. I use imaps with dovecot for managing my maildir. I have added ssl parameters to the configuration file (see below) and I required certificate from the client (to avoid man in the middle attack and to get access only for client with user certificate). To get this "ssl_require_client_cert" is set to yes. Ok, now imaps works perfectly. But since a certificate is required webmail authentication (localhost) and SASL (postfix auth trough dovecot socket mechanism) don't work. Webmail => dovecot: imap-login: Disconnected (cert required, client didn't start TLS): method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Postfix => postfix/smtpd[71640]: warning: TOTO[X.A.B.C]: SASL PLAIN authentication failed: Client didn't present valid SSL certificate That's normal. But 127.0.0.1 client(network) is considered by dovecot as secure, so won't the auth possible without certificate ? Can't we make two auth policy to make secure (client crt require) for public IP/client and less "secure" (without crt client) for local process (postfix) and local newtwork(127.0.0.1) for roundcube ? I see section "auth default { ... }" and is used by ... default ! But can we make an other one to make this two particular authentication on the same "instance" ? Thank you. And then my configuration : operating system => FreeBSD 7.1 dovecot --version => 1.2.8 dovecot -n => # 1.2.8: /usr/local/etc/dovecot.conf # OS: FreeBSD 7.1-RELEASE i386 ufs protocols: imap listen: 127.0.0.1 ssl_listen: X.Y.Z.T ssl: yes ssl_ca_file: /usr/local/etc/dovecot/CAclient.pem ssl_cert_file: /usr/local/etc/dovecot/imaps.pem ssl_key_file: /usr/local/etc/dovecot/imaps.key ssl_verify_client_cert: yes login_dir: /var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login verbose_proctitle: yes first_valid_uid: 1000 first_valid_gid: 1000 mail_privileged_group: mail mail_location: maildir:/jails/mails/%d/%n imap_client_workarounds: delay-newmail netscape-eoh tb-extra-mailbox-sep lda: postmaster_address: postmaster@SOMETHING hostname: SOMETHING_ELSE sendmail_path: /usr/sbin/sendmail auth default: mechanisms: plain login username_format: %Lu passdb: driver: passwd-file args: username_format=%n /jails/mails/dov_pass/%d/usr_pas userdb: driver: passwd-file args: username_format=%n /jails/mails/dov_pass/%d/usr_pas ssl_require_client_cert = yes ssl_username_from_cert = no socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: wheel master: path: /var/run/dovecot/auth-master mode: 384 Best regards, _________________________________________________________________ Consultez gratuitement vos emails Orange, Gmail, Free, ... directement dans HOTMAIL ! http://www.windowslive.fr/hotmail/agregation/

[Dovecot] Question about dovecot imap proxy
by Monika Janek 29 Apr '10

29 Apr '10

Hi everyone! I have dovecot (1.2.11) on one our external mail servers acting as a proxy. The client (ifor now, my iphone) connects fine via ssl to the external mailserver but I can't seem to get a secure connection now to the internal destination imap server (between external mail server and internal imap server, it's going through port 143). Running tcpdump, I can clearly see my password being transmitted on our internal network. I read the addition to the documentation about dovecot proxy but I'm not sure where to add these variables: In v1.2.rc4+ the connections to destination server can be TLS/SSL encrypted by returning: * ssl=yes: Use SSL and require a valid verified remote certificate. *WARNING: Unless used carefully, this is an insecure setting!* Currently host must be an IP address, so this setting accepts any certificate signed by a trusted CA. The host name isn't checked in any way against the certificate's CN. The only way to use this securely is to only use and allow your own private CA's certs, anything else is exploitable by a man-in-the-middle attack. * ssl=any-cert: Use SSL, but don't require a valid remote certificate. * starttls: Use STARTTLS command instead of doing SSL handshake immediately after connected. Can anyone point me in the right direction? Thanks so much! :) -- Monika Janek Systems Administrator, Side Effects Software Toronto, Ontario Canada 416-504-9876 x207 www.sidefx.com

[Dovecot] Problems with Mailbox is in inconsistent state, please relogin.
by Daniel Machado Grilo 29 Apr '10

29 Apr '10

Dear Dovecot users, I'm a sysadmin in a company that recently migrated the IMAP from courier-imap to dovecot :-) *urray* Everything with the perl migrating scripts (version 1.0) went with OKs and it was a lot of fun (and pray) to move 400Gb of mails and migrate.. and everything is working even better :-) The problem is for some outside users that use webmails, like: - Squirrel - Roundcube - Horde They claim that the connection is constantly dropping.. You might say now: "Webmail's fault!!!" as I said in the beginning :) But the IMAP logs shows SEVERAL times (almost every 10mins ?!): Apr 28 21:10:48 olive dovecot: IMAP(rcoelho): Maildir /cluster/mail/mailboxes/rcoelho sync: UID inserted in the middle of mailbox (192736 > 192720, file = msg.LDW0C) Apr 28 21:10:48 olive dovecot: IMAP(rcoelho): Disconnected: Mailbox is in inconsistent state, please relogin. Apr 28 19:14:11 olive dovecot: IMAP(pcorreia): Maildir /cluster/mail/mailboxes/pcorreia sync: UID < next_uid (7874 < 7875, file = msg.5BNVC) Apr 28 19:14:12 olive dovecot: IMAP(pcorreia): Disconnected: Mailbox is in inconsistent state, please relogin. and so on. I read somewhere on the web that configuring the mbox_lazy_write=no should work .. it did not :-) I have CentOS 5.4 in our mailserver, so the version of dovecot is not the latest (it is 1.0.7).. But of course, this is production environment and I don't want to update if its not needed :-) So my questions are: - Is this a known bug for this version and I have to upgrade ? - Is this a problem in my configs for dovecot ? - Can this be other problem than dovecot ? -- so probably i should be able to add more debug anoying messages to our logs ? - Probably something went wrong in the migration for these maildirs? So now what can we do to fix this ? Our mail is working and, at the moment, I found 3 users with this error.. They have about 10Gb of mail each, I don't think this is a problem for dovecot.. only for our storages.. :-) Tks for your patience, Best Regards!

Hello I use dovecot, postfix, mysql and squirrelmail as a mail server. it works well. Meanwhile I am novice at postfix. As you know, there is a change_password plugin on squirrelmail. I wish to add change_password plugin on squirrelmail. I couldn't find how to integrate postfix and change_password. How can I add it ?

Re: [Dovecot] returned error 83 (Out of memory)
by J Contad 28 Apr '10

FYI, sorted out this issue by taking out a specific email manually. Not sure if it helps, but the email had these attributes: - X-Mailer is PHPMailer [version 1.73] - References: header is quite large, and contains email addresses external to the sender and I's conversation. Removing the email fixed the issue. -- John

[Dovecot] somebody using Net::Sieve (Perl) with dovecot 1.2.11?
by Heiko Schlittermann 27 Apr '10

27 Apr '10

Hello, I've just (hopefully) fixed some issue with Net::Sieve (0.05) to cooperate with a current (1.2.11) dovecot managesieve server and STARTTLS. Does somebody use this Perl library? If yes, did it work for you (STARTTLS triggers the problem)? If not, which other (Perl) library do you use?

[Dovecot] Anyone successfully using expire plugin?
by Thomas M Goerger 23 Apr '10

23 Apr '10

Anyone out there using expire? At this point, I'm not sure that it's even running. It was touching the plugin libraries yesterday, but doesn't appear to be doing so today. The plugin directory wasn't explictly set, so I've done so now, but it's still not touching these. Anyone have a cf file I could take a look at, or any ideas as to what might be happening?

[Dovecot] How can I make dovecot aware of user's email aliases?
by Ian P. Christian 23 Apr '10

23 Apr '10

Sieve will not reply to mail it doesn't think was sent directly to a user. I use an SQL auth backend, and a user might login as user1(a)domain.com. What method can I use to inform dovecot that user2(a)domain.com is a forward to user1(a)domain.com, such that the vacation auto response will fire when user2(a)domain.com is emailed (therefore, the mail ends up in user1(a)domain.com's mailbox). -- Blog: http://pookey.co.uk/blog Follow me on twitter: http://twitter.com/ipchristian

[Dovecot] best choice of user database file to work with postfix?
by Phil Howard 23 Apr '10

23 Apr '10

I'm setting up a Postfix and Dovecot combination. What I want to do is have a user database that (1) is not running from some engine (so not LDAP or SQL or such) ... and (2) is completely disassociated from system users (e.g. most email users are not in /etc/passwd and most /etc/passwd users are not email users). Ideal would be a one-file solution, which can be managed by text editing or simple command line tools. But what I want is ONE file that both Postfix (for valid recipients) and Dovecot (for user login authentication) can use together. An alternative is some way to get Postfix to go through Dovecot to query for users (at the time of mail arriving on SMTP so it doesn't queue anything that would later be rejected). This is a smallish setup on one server, with probably a max of 50 to 100 users and 50 or so role account mailboxes over the next year or two. Any recommendations?

Hello, I would like to monitor users quotas in Dovecot but I don't find a way to do it for every user. Acutally I can log in with user & password to get the users quota but wat I need is a way to monitor the quota of every user with e.g an admin user which would have an acces to the quota of each mailbox. Is there a way to this? Thanks for your help.

[Dovecot] Quota Issue
by Peter Fraser 21 Apr '10

21 Apr '10

Hi All I'm using dovecot version 1.2.4_1 and I noticed something strange. I checked the list but so far I haven't found anything that exactly fits my setup. I'm using maildirs and ldap as a backend to authenticate. A user went over quota, realized it and proceeded to delete a lot of email. Even now, after about 15 minutes, the quota indicator is still showing that he is over quota even though the users mailbox size is down by over 200MB. Why isn't Dovecot showing the change, and is there a way around this? Thanks for any help.

[Dovecot] corrupted index cache file, physcial size, in migration to snow leopard
by Norman Packard 21 Apr '10

21 Apr '10

Hi, I am in the middle of migrating a server from Apple's leopard to snow leopard. Having big problems with migrating mail to dovecot. The version is: # dovecotd --version 1.1.17apple0.5 and I use the migration script provide by Apple, /usr/libexec/dovecot/migrate_mail_data.pl The current problems concern migrating imap accounts. The old data typically shows up to mail clients as only partially migrated, with some issues there, like folders change from being listed on the server to being listed locally, but the biggest problem is that many many messages and folders have disappeared from view. But on the server, they seem to be there, in their correctly migrated place. The log files are full of messages like the ones below, which I'm guessing has something to do with the problem. The number of files with this problem is huge. Are there any scripts to rebuild the index cache files with correct physical sizes? Thanks in advance for any help!

[Dovecot] Checkpassword/prefetch/master_user and problems
by Emerson Pinter 20 Apr '10

20 Apr '10

Hi. I'm trying to use checkpassword for simple auth and masteruser auth. I have two programs, one called checkpassword-master (for masteruser lookup) and another called checkpassword for normal passdb and userdb lookup). All works fine for non-masteruser authentication (in this case dovecot makes a single call to checkpassword binary). But if a master-user authenticates, dovecot execute checkpassword-master binary, and then executes checkpassword binary. Checkpassword binary receive the MASTER_USER env and do all the checks correctly, when checkpassword finish, dovecot logs this message "auth(default): checkpassword: sighandler called for unknown child" and authentication fails... I'm trying checkpassword-reply and fd4 too, on 1.2.11 and 2.0b4, no success. Below is my config: auth default { mechanisms = plain passdb checkpassword { args = /srv/dovecot/checkpassword } passdb checkpassword { args = /srv/dovecot/checkpassword-master master=yes pass=yes } userdb prefetch { } } Anybody can help me ?

[Dovecot] zero sized messages in Maildir, corrupt filenames ?
by Rodolphe Buret 20 Apr '10

20 Apr '10

Hi, I'm starting to see more and more duplicates in my cur directory. they seem to be a copy of an incoming mail (messages share the same date) but they appears in the client as a message without subject and without sender or body. Their filename starts with an underscore and the 4th letter is a %. The rest of the filename is random (but it also includes my hostname). Which program could create such a filename ? If it's in the cur directory, it can only be dovecot, right ? Example of 2 probably related messages in the cur folder: 1785 Apr 20 09:18 msg.zMeU:2,d 0 Apr 20 09:18 _J9C%jVVzLB.{myhostname}:2, In addition, it seems that since we have started to use thunderbird 3, indexes are often corrupt, mailboxes needs reconstruction and so on. Could it be an incompatibility with my version of dovecot ? I've disabled my thunderbird filters that were moving the incoming mail automatically, no difference. I use no antivirus (linux imap client mainly). I can (probably) upgrade to dovecot-1.2.11-3_108 but I'd like to be sure that I won't create more problems before doing it.

[Dovecot] permission denied, no logs
by Shane Brooks 19 Apr '10

19 Apr '10

Hi, We have a sendmail/dovecot/squirrelmail installation that was working ok except for deleted files showing in the list with a [d] beside it. In trying to fix that issue, I apparently made a new error appear in the left navigation area: ERROR: Could not complete request.

[Dovecot] dovecot-1.2-sieve sending vacation replies regardless of recipient (patch)
by Mark Washenberger 19 Apr '10

19 Apr '10

I want a way to send VAR messages without having to specify up front all of the addresses for which such VARs should be sent. I realize this goes against rfc 3834, but it seemed reasonable to add a tag to the vacation command to skip the [to, cc, bcc, ...] recipients check. The patch I made is attached. The new usage with this patch is: vacation [":days" number] [":subject" string] [":x_any_address"] [":from" string] [":addresses" string-list] [":mime"] [":handle" string] <reason: string> What do you think of this patch? Is there a better way to accomplish the same thing without writing a patch? Is there a better way to write this patch to make it a cleaner feature or easier to maintain? Could this ever be part of the mainline? Mark Washenberger Rackspace Hosting Software Developer, Email & Apps mark.washenberger(a)rackspace.com

[Dovecot] sieve plugin - reject sends MDN. Can it 550 reject ?
by Ken A 19 Apr '10

19 Apr '10

I'm using dovecot-1.2-sieve-0.1.15 with dovecot-1.2.11. I have a reject test filter that looks like this: require "reject"; if header :contains "subject" "reject" { reject "bye"; } Is there any way to get a "reject" filter to send back a 550 reject as detailed in http://ietfreport.isoc.org/idref/rfc5429/#section-2.5 rather than a MDN? The MDN can result in blowback spam. :-( Thanks, Ken -- Ken Anderson Pacific Internet - http://www.pacific.net

[Dovecot] PostgreSQL driver supporting [round-robin] load balancing and redundancy [LONG]
by Rainer Weikusat 18 Apr '10

18 Apr '10

One of the things my employer uses dovecot for is as mail download server for an 'e-mail purification service' (AV/ anti-spam) for smartphones. The service itself presently runs on a rented server somewhere in the UK and the corresponding 'web service' front-end and user account/ mail account database resides on a server in Germany. The UK dovecot server uses the PostgreSQL server on the German machine for user authentication. The latter is reachable using two entirely different 'internet paths' and there was an outage of several hours on one of them a couple of weeks ago. This prompted some frantic network reconfiguration efforts in order to get the abovementioned service going again and resulted in the conviction that - ideally - the dovecot server should be capable of using connections to multiple PostgreSQL servers (or a single server reachable via several IPs) simultaneoulsy, distributing requests among them, and should be capable of detecting a possible problem on one of the db server connections and use the still functioning ones to continue operations. After having spent about eight hours reading through the code of existing pgsql driver, I concluded that modifying that in order to achieve the goals outlined above would require some major brain surgery with a high chance of causing a lot of collateral damage in the course of that and that writing a new driver providing the sought-after feature set was the better idea. Which is the point of this e-mail. Example Usage ------------- Multiple connections can be specified in an ordinary connect-string by separating the necessary parameters with a ;;;-sequence. For the server I was writing about above, this looks like: connect = host=1.1.1.1 dbname=mailgate user=mailgate_user password=secret sslmode=require ;;; \ host=2.2.2.2 dbname=mailgate user=mailgate_user password=secret sslmode=require Leading and trailing whitespace in a connect sub-string is ignored. Basic Operation --------------- After having split the connect string, the driver creates a connection structure (struct multi_pgsql_pgc) for each connection specification contained in that and initiates an asynchronous connect for each. As the actual connections become ready, they are put onto a (linked list) (FIFO) queue of 'connections which are ready'. When a query is submitted to the driver, the first connection structure is removed from the ready list and used to execute the query. After this has finished, the connection is added to the end of the 'connections which are ready' list. If no connection is ready at the time a query was submitted, the query is put on a FIFO queue of queries which will be executed as the resources to actually do so become availabe. Each query has a lifetime of 60 seconds (arbitrary). A query which couldn't be started before his lifetime was over will be aborted with a timeout error. A connection which is currently being used to execute a query will be considered dead if no forward progress of any kind has happened for 20 seconds (also arbitrary). If this happens (or if some kind of I/O error occurs), the existing connection will be closed and an asychronous connect on a newly created one will be started. Assuming the lifetime of the query isn't yet over, it will either be started again on another available connection or pushed back onto the front of the query queue, causing it to be started as soon as a connection becomes available. Attemtps to reestablish the failed connection will continue (with 5 seconds of delay between each) in the background until success. Design Overview --------------- struct multi_pgsql_pgdb & routines working on that provide both the 'simple' query interface and transaction support. struct multi_pgsql_pgc represents a database connection. The result interface is implemented as struct multi_pgsql_result & assorted subroutines. Transactions are provided by a struct multi_pgsql_transaction_context which contains a linked-list of transaction subqueries (struct multi_pgsql_transaction_subquery). A 'class hierarchy' of 'query classes' is used to provide the different kinds of 'queries' supported by the driver (simple queries, simple synchronous queries, transaction queries, synchronous transaction queries). The complete hierarchy itself looks like this: multi_pgsql_query / \ / \ multi_pgsql_simple_query multi_pgsql_transaction_query / \ / \ / \ / \ multi_pgsql_user_query multi_pgsql_sync_query \ / \ / \ multi_pgsql_async_transaction_query multi_pgsql_sync_transaction_query Notable Difference to the pgsql Driver -------------------------------------- sql_exec This interface is not implemented. It is (as far as I can tell) not used anywhere except inside the sqllite driver. It cannot be used for queries which return information because there is no way to access this information and it can neither generally be used for queries which cause side effects since it cannot be determined if execution was successful (the only possible use I can think of is actually a rollback after a failed transaction). sql_result_get_field_value_binary Not implemented. Appears to be unused and the way I understand the libpq programming documentation, the only way to retrieve a binary result to some query is to use PQsendQueryParams or PQsendQueryPrepare and request that some columns are returned in binary. Nothing like this is supported in the present, abstract SQL database interface. synchronous query execution Because background connection reestablishment might still be going on after a synchronous query has been executed, it is necessary to switch any timeouts/ io operations registered to the ioloop used for synchronous query execution back to the main ioloop. The code implements this by using io_loop_set_current to temporarily restore the original ioloop, unregistering and registering any timeouts/ io-requests possibly associated with one of the existing database connections, switching back to the synchronous execution ioloop afterwards and then destroying that via io_loop_destroy. This works but is probably not exactly how the existing interfaces were supposed to be used. error messages for synchronously committed transaction These are put onto the data stack by the commit_s subroutine which will hopefully (judging from the dict-code, this should work, too) be sufficient to enable them to survive until someone higher up in the callchain wants to look at them. Remarks on the Patch -------------------- Created against dovecot-1-2-cf3fe573a560. Applies cleanly to 1.2.11. Applies to 2.0.beta4 with a rejection because of a feature which doesn't exist anymore. The result can be compiled but it hasn't been tested. ---- Index: dovecot/configure.in =================================================================== RCS file: /sysdata/cvs/dovecot/configure.in,v retrieving revision 1.1.1.2 retrieving revision 1.1.1.2.6.9 diff -u -r1.1.1.2 -r1.1.1.2.6.9 --- dovecot/configure.in 15 Mar 2010 18:18:14 -0000 1.1.1.2 +++ dovecot/configure.in 5 Apr 2010 16:16:03 -0000 1.1.1.2.6.9 @@ -159,6 +159,11 @@ [ --with-sqlite Build with SQLite3 driver support], TEST_WITH(sqlite, $withval), want_sqlite=no) + +AC_ARG_WITH(multi-pgsql, +[ --with-multi-pgsql Build with PostgreSQL driver supporting multiple connections], + TEST_WITH(multi-pgsql, $withval), + want_multi_pgsql=no) AC_ARG_WITH(lucene, [ --with-lucene Build with CLucene full text search support], @@ -1969,7 +1974,12 @@ LIBS=$old_LIBS fi -if test $want_pgsql != no;

[Dovecot] windows live mail + dovecot and nfs
by Anes Muhametov 17 Apr '10

17 Apr '10

Hi all. My clients have got problem accessing dovecot by "Windows live mail (Windows 7)" client. The problem is that users can't delete two or more folders one-by-one. There is no errors deleting first folder (new dir /storage/vol1/mail/domain/user/Maildir/..DOVECOT-TRASHED appeared and wasn't deleted). If I try to delete second one, error occurs (user, domain, IP address changed): dovecot: IMAP(user@domain): unlink_directory(/storage/vol1/mail/domain/user/Maildir/..DOVECOT-TRASHED) failed: Directory not empty I'm using dovecot 1.2.10 @FreeBSD 7.2-RELEASE-p1 amd64 and NFS storage backend. dovecot -n # 1.2.10: /usr/local/etc/dovecot.conf # OS: FreeBSD 7.2-RELEASE-p1 amd64 syslog_facility: local7 protocols: imap imaps pop3 pop3s ssl_cert_file: /etc/ssl/1.crt ssl_key_file: /etc/ssl/1.key.unsec disable_plaintext_auth: no verbose_ssl: yes shutdown_clients: no login_dir: /var/run/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login login_greeting: mail server ready. login_process_per_connection: no login_process_size: 512 login_processes_count: 60 login_max_processes_count: 256 login_max_connections: 100 max_mail_processes: 4096 mail_max_userip_connections(default): 50 mail_max_userip_connections(imap): 50 mail_max_userip_connections(pop3): 30 verbose_proctitle: yes first_valid_uid: 90 last_valid_uid: 90 first_valid_gid: 90 last_valid_gid: 90 mail_privileged_group: mail mail_location: maildir:%h/Maildir mmap_disable: yes mail_nfs_storage: yes mail_nfs_index: yes lock_method: dotlock maildir_copy_preserve_filename: yes mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_process_size: 128 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 imap_client_workarounds(default): delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(imap): delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(pop3): pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh lda: postmaster_address: postmaster(a)domain.ru mail_plugins: quota sendmail_path: /usr/sbin/sendmail log_path: /var/log/dovecot/deliver.log info_log_path: /var/log/dovecot/deliver.log auth default: mechanisms: plain login cram-md5 cache_size: 262144 cache_ttl: 180 cache_negative_ttl: 60 failure_delay: 1 worker_max_count: 2000 process_size: 512 passdb: driver: sql args: /usr/local/etc/dovecot-sql.conf userdb: driver: prefetch userdb: driver: sql args: /usr/local/etc/dovecot-sql.conf socket: type: listen master: path: /var/run/dovecot/auth-master mode: 384 user: user group: domain plugin: quota: maildir:Quota Here is listing of ..DOVECOT-TRASHED: ls -la /storage/vol1/mail/domain/user/Maildir/..DOVECOT-TRASHED: total 16 drwx------ 2 user user 4096 Apr 9 11:32 . drwx------ 27 user user 8192 Apr 9 11:41 .. -rw------- 1 user user 156 Apr 9 11:32 .nfs.014cd02e.ffffd11b4.4 -rw------- 1 user user 17 Apr 9 11:32 .nfs.014cd031.ffffd11b4.4 fstat output: [root@ /storage/vol1/mail/domain/user/Maildir/..DOVECOT-TRASHED]# fstat .* USER CMD PID FD MOUNT INUM MODE SZ|DV R/W NAME root fstat 82081 wd /storage/vol1 32454159 drwx------ 4096 r . user imap 53042 7 /storage/vol1 40573622 -rw------- 156 rw .nfs.014cd02e.ffffd11b4.4 user imap 53042 9 /storage/vol1 40573631 -rw------- 17 rw .nfs.014cd031.ffffd11b4.4 root bash 22223 wd /storage/vol1 32454159 drwx------ 4096 r . # ps uxwa|grep user user 53042 0.0 0.1 9812 2400 ??

Hi there! I am new to imap "Command Line" and trying to write a script doing the following on a dovecot imap server: - APPEND a message (e.g. to Drafts) - get the ID to reopen the message for reading In short: How do i get the ID back from the APPEND command or which command has to be invoked to get the uid of the newly added message? Thank you!

[Dovecot] mysql log entry
by Terry Barnum 16 Apr '10

16 Apr '10

I'm sure this is a really newbie question, but I notice in /var/log/mail.log that there are between 3 and 15 of the following log entries every day for the last five days, which is far back as my logs go--what do they mean? Apr xx hh:mm:ss mail dovecot[109]: auth-worker(default): mysql: Connected to localhost (postfix) Is it dovecot connecting to mysql for password or user info? If so, wouldn't it be more frequent? I've got 20 users with some connecting from outside many times per day. Thanks, -Terry

[Dovecot] Problems with masteruser

I have very strange problem with masteruser. See two logs below: # telnet localhost 143 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE STARTTLS AUTH=PLAIN AUTH=LOGIN] Welcome to our post server! x login nevorotin password x 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 x list "" "*" * LIST (\HasNoChildren) "/" "INBOX" x OK List completed. x getacl INBOX * ACL "INBOX" "nevorotin" lrwstipekxacd x OK Getacl completed. All work perfectly. And then I log in throw masteruser: # telnet localhost 143 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE STARTTLS AUTH=PLAIN AUTH=LOGIN] Welcome to our post server! x login nevorotin*master masterpassword x 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 x list "" "*" * LIST (\Unmarked) "/" "INBOX" x OK List completed. x getacl INBOX x NO [NONEXISTENT] Mailbox doesn't exist: INBOX I've turned on debug logging, but there aren't any errors. I only see that masteruser succesfully logged in as nevorotin. How can I make a masteruser login to user account exactly the same as simple user login? Now it don't work at all [?] I use 1.2.10 version of dovecot.

Re: [Dovecot] zlib Plugin Dovecot 2.0
by Alex Baule 16 Apr '10

16 Apr '10

Hi Paschal You do not understand what I want. I developed a plugin based on the zlib plugin, but want to port it to dovecot 2.0. There are some differences in the 2.0 plugin, which I did not quite understand how it works for me to readjust it in my plugin. As in the source code there are not many comments, I do not quite know what each function does, if they are all necessary in my adaptation. In developing the plugin in version 1.4, Timo helped me a lot. What I need to know is how the hooks on write emails do this, and what the differences in the read function, since the code is different from version 1.4 to 2.0.

[Dovecot] 2.0beta4 and latest Mercurial: Folder not SELECT-able until LIST-ed
by B. Johannessen 16 Apr '10

16 Apr '10

Have a look at the attached dialog. It shows the folder "shared/a(a)db.org/Archive" not being SELECT-able until after it's been mentioned in a LIST response. This can't possibly be right, can it? Bob
