[Dovecot] 1.1.8 upgrade to 1.2
by Guy 23 Jul '09

23 Jul '09

Hi, I'm hoping to upgrade to 1.2 in the next couple of days. I remember seeing something mentioning some sort of config change, but unfortunately I don't remember where I saw it nor what the config option was. Are there any gotchas I need to watch out for in the change to 1.2 from 1.1.8? I've included dovecot -n below. Thanks Guy #dovecot -n # 1.1.8: /etc/dovecot/dovecot.conf # OS: Linux 2.6.24-23-server x86_64 Ubuntu 8.04.2 protocols: imap imaps pop3 pop3s listen(default): *:143 listen(imap): *:143 listen(pop3): *:110 ssl_listen(default): *:993 ssl_listen(imap): *:993 ssl_listen(pop3): *:995 ssl_cert_file: /etc/ssl/certs/imapd.pem ssl_key_file: /etc/ssl/private/imapd.pem disable_plaintext_auth: no verbose_ssl: yes login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login login_greeting: Dovecot ready on mink.domain.org. login_process_per_connection: no login_processes_count: 5 login_max_processes_count: 1024 login_max_connections: 1024 max_mail_processes: 1024 mail_max_userip_connections: 20 verbose_proctitle: yes mail_location: maildir:%h/Maildir/ mail_debug: yes mail_full_filesystem_access: yes mmap_disable: yes dotlock_use_excl: no mail_nfs_storage: yes mail_nfs_index: yes lock_method: dotlock mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugins(default): imap_quota quota mail_plugins(imap): imap_quota quota mail_plugins(pop3): quota mail_log_max_lines_per_sec: 30 imap_client_workarounds(default): outlook-idle delay-newmail netscape-eoh imap_client_workarounds(imap): outlook-idle delay-newmail netscape-eoh imap_client_workarounds(pop3): pop3_uidl_format(default): %08Xu%08Xv pop3_uidl_format(imap): %08Xu%08Xv pop3_uidl_format(pop3): %08Xv%08Xu pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh namespace: type: private separator: / inbox: yes list: yes subscriptions: yes namespace: type: private separator: / prefix: mail/ location: maildir:%h/Maildir/ hidden: yes subscriptions: yes auth default: cache_size: 2048 cache_ttl: 300 cache_negative_ttl: 1 username_chars: abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@' master_user_separator: * debug: yes passdb: driver: passwd-file args: /etc/dovecot/dovecot-master.pwd master: yes passdb: driver: sql args: /etc/dovecot/dovecot-mysql.conf userdb: driver: sql args: /etc/dovecot/dovecot-mysql.conf plugin: quota: maildir quota_rule: *:storage=100M quota_rule2: Trash:ignore -- Don't just do something...sit there!

[Dovecot] flat file dict
by Sven Strickroth 23 Jul '09

23 Jul '09

Hi, I'm using version 1.2.1 with acl. How do I use acl_shared_dict? Especially with file:-dictionary. What's the layout of that file? Is it possible that the file is ignored with the current version? If the file doesn't exist or isn't readable, I don' get any error message. Best regards, Sven

[Dovecot] Released Sieve v0.1.9 for Dovecot v1.2.1
by Stephan Bosch 23 Jul '09

23 Jul '09

Hello Dovecot users, Relatively many bugs and problems were reported recently in a short period of time. Apparently, now that Dovecot v1.2 is finally stable, the new Sieve plugin is also starting to get used much more. No known bugs remain. Let's hope I didn't spawn any new ones. Apart from the bugfixes I made the deprecated notify plugin implementation compatible with CMUSieve. You can use it, but keep in mind that the (rather stupid) denotify command is not (yet) implemented and that the $text$ substitution does not work (yes, there is a world of differences compared to enotify). Changelog Sieve v0.1.9: * Removed the unfinished sieve-filter tool from the default build. It is now only built when the --with-unfinished-features switch is supplied during configure. + Started building support for the ereject version of the reject action, which has a preference to use an SMTP/LMTP protocol error in stead of a bounce message. This is to be used to make the Sieve plugin honour Deliver's -e parameter. This is not yet finished and not built by default. + Improved 'Permission denied' error messages just like Dovecot does, precisely specifying what permission is missing to access or create a file. + Added additional headers to the list of allowed headers for the address test. The restrictive nature of the address test is not always appropriate. Still thinking of a better, less restrictive implementation. + Made the deprecated notify extension compatible with the old CMUSieve plugin. However, the denotify command and the $text$ substitution are not yet supported. + Made the discard action log a message to avoid confusion about disappearing messages. - Fixed behavior of fileinto when delivering into a namespace prefix. It now uses silent delivery into INBOX as fallback. - Fixed logging of folder namespace prefix upon delivery into a prefixed namespace. Formerly it only logged the bare folder name. - Fixed a potential segfault in the argument validation. It didn't surface because no command could have a :tag followed by an associated parameter as last argument. - Fixed segfault bug occuring in envelope test when performed on null (<>) envelope path. The fix involves a rather large restructuring of the code to make sure envelope addresses are properly handled everywhere (bug reported by Nikita Koshikov) - Envelope: fixed bug in application of address parts; failure to obtain the part would cause inappropriate match success (bug reported by Ron Lee) - Fixed extension conflict checks during validation. It could sometimes produce useless errormessages. This is currently only used by the deprecated extensions. - Forgot to remove old explicit storage library dependency (patch by Arkadiusz Miskiewicz). - Fixed compiler warnings on certain platforms regarding the use fwrite for outgoing message construction -- The releases are available as follows: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.9.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.9.tar.gz.sig -- Have fun testing the new releases and don't hesitate to notify me when there are problems.

[Dovecot] Compiling Dovecot
by Jason Silkey 23 Jul '09

23 Jul '09

I'm attempting to compile Dovecot 1.2.1 from source with support for ManageSieve, with little success. ./configure seems to complete successfully, but make fails with the message: make: *** No targets. Stop. I checked the Makefile, and it's empty. I run into the same problem no matter the configure options, with or without the managesieve patch applied, and even with earlier versions (I also tried 1.2.0 and 1.1.17 just to see if it would work, but no go). I've had no problems compiling other software, so I'm at a bit of a loss here. Any thoughts?

[Dovecot] PAM_USER falsely assumed immutable
by Aaron Richton 23 Jul '09

23 Jul '09

In 1.2.1 there's: passdb-pam.c:230 status = pam_get_item(pamh, PAM_USER, &item); passdb-pam.c:237 auth_request_set_field(request, "user", item, NULL); so "item" is PAM_USER, which is then checked by auth_request_set_field: 1022 if (strcmp(request->user, value) != 0) { 1023 auth_request_log_debug(request, "auth", 1024 "username changed %s -> %s", 1025 request->user, value); that it hasn't changed. You're not allowed to assume that PAM_USER doesn't change. See, for example, http://www.kernel.org/pub/linux/libs/pam/Linux-PAM-html/adg-security-user-i… to say nothing of the fact that Rutgers has PAM modules that do exactly that (change PAM_USER). This check needs to be relaxed (or, perhaps if you want a config directive for DontComplyWithThePAMSpec = true, you can have a tunable). Can this be as simple as ditching the call to auth_request_set_field, or is there concern over interactions between PAM and other auth features?

[Dovecot] Defunct processes w/ v1.2.1
by Chris O'Regan 22 Jul '09

22 Jul '09

I have limited information at the moment (currently distracted by other projects) but I'm hoping that someone has already found and solved this problem. I have a v1.2.1 installed on my development box waiting for me to tinker with the configuration. On several occasions, I have noticed that all the dovecot processes are listed as "defunct". I don't recall seeing anything significant in the logs the last time I checked. The system is not under any load. Has anyone else encountered this before? If not, I will dig deeper. BTW, ignore the fd limit warning below; limits are set in the init script. # /local/bin/dovecot -n # 1.2.1: /local/pkg/dovecot-1.2.1/root/etc/dovecot.conf Warning: fd limit 1024 is lower than what Dovecot can use under full load (more than 10240).

[Dovecot] virtual plugin question
by Nikita Koshikov 22 Jul '09

22 Jul '09

Hello list, After enabling virtual plugin in dovecot config, I got imap segmentation faults from time to time. I can't say what event trigs this behavior, but in logs I see: Jul 22 13:55:01 dovecot: Error: child 20908 (imap) killed with signal 11 (core dumped) Jul 22 13:56:43 dovecot: Error: child 19466 (imap) killed with signal 11 (core dumped) Jul 22 14:06:16 dovecot: Error: child 22629 (imap) killed with signal 11 (core dumped) Jul 22 14:08:17 dovecot: Error: child 22879 (imap) killed with signal 11 (core dumped) Here is my config section, which I added to enable virtual plugin: namespace private { prefix = Company/ separator = / location = virtual:/var/mail/virtual subscriptions = no } and "virtual" to mail_plugins in imap and lda section. Full dovecot -n config provided at the end of this message. I'm not sure, if it is save to enable virtual location for all users using the same path, but the main goal for me - to create dovecot-virtual files once for all users.

[Dovecot] Problem with INTERNALDATE when the year in localtime and GMT different
by 도원철 21 Jul '09

21 Jul '09

In my thought utc_offset function in src/lib/utc-offset.c returns wrong offset value when the year in localtime and GMT different. /* max offset of 24 hours */ if (ltm.tm_yday < gtm.tm_yday) offset = -24 * 60; else if (ltm.tm_yday > gtm.tm_yday) offset = 24 * 60; else offset = 0; I think this code should be modified as followings. /* max offset of 24 hours */ if ((ltm.tm_year == gtm.tm_year && ltm.tm_yday < gtm.tm_yday) || (ltm.tm_year < gtm.tm_year)) offset = -24 * 60; else if ((ltm.tm_year == gtm.tm_year && ltm.tm_yday > gtm.tm_yday) || (ltm.tm_year > gtm.tm_year)) offset = 24 * 60; else offset = 0; On 1 Jan. 2009, I found an error related to this code. The intrenal date of message recieved at 01-Jan-2009 07:17:38 was not display as it received. The protocol log was as followings. FETCH (INTERNALDATE “01-Jan-2009 07:17:38 -3900” RFC822.SIZE 1597 FLAGS (\Seen) ENVELOP (“Thu, 1 Jan 2009 07:17:38 +0900 (KST)” … The INTERNALDATE must be “01-Jan-2009 07:17:38 +0900”, but it was "01-Jan- 2009 07:17:38 -3900". This error may be caused by the bug in utc_offset.c. How do you think?

[Dovecot] [Bug] dovecot deliver v1.2.1 segfaults
by Nikita Koshikov 21 Jul '09

21 Jul '09

Hello list, I have noticed strange dovecot behavior with exim system-filter. I'm using exim+dovecot setup. My exim configuration have system filter enable, which restrict some attachments, like exe, vbs etc. When message with forbidden attachment received, exim accept the message, then construct bounce-message(Reject reason + original message) and returns it to sender. Trying to deliver such messages, I always get segmentation faults and message stayed in exim's queue. Others common delivers work fine. This only happens with bouncing system-filter messages. Steps to reproduce: 1) Create message with forbiden attachment 2) Send message. 3) Get segmentation fault. Here is more details: exim -d+all -M 1MSn7r-0003hN-BG (this command runs delivery from exim's queue) 13:14:23 11570 --------> koshikov.n(a)domain.com <-------- 13:14:23 11570 locking

[Dovecot] vpopmail and shared mailbox
by David Fuchs 20 Jul '09

20 Jul '09

hi all, I'm a long time courier-imap user and just switched to dovecot-1.2.1. my MTA is qmail and all user accounts are virtual vpopmail users. getting dovecot to work was mostly painless, but I am desperately trying to share a user's mailbox and can't seem to figure out how. unfortunately the documentation is not very helpful. I am trying to share the mailbox /home/vpopmail/domains/ example.com/someuser/Maildir here's what I put in dovecot.conf: namespace shared { separator = . prefix = shared.%%u. location = maildir:/home/vpopmail/domains/%%d/%%n/Maildir:INDEX=~/Maildir/shared/%%u subscriptions = no list = yes } I then logged in as someuser and did a "setacl anyone Inbox lrip". /home/vpopmail/domains/example.com/shared-mailboxes.db now contains an entry shared/shared-boxes/anyone/someuser(a)example.com 1 and /home/vpopmail/domains/example.com/someuser/Maildir/dovecot-acl has anyone ilpr however, when I connect to the server, the client does not see the "shared" namespace. also, dovecot seems to be creating empty shared-mailboxes.db in /home/vpopmail/domains/example/ (missing .com!). I'm very confused at this point, but I'm sure someone has gotten this to work and can help me out. fwiw, the output of dovecot -n is appended. thanks! - Dave.

[Dovecot] Problem with quota-dict
by Sascha Bendix 20 Jul '09

20 Jul '09

Hi, I wanted to migrate a mailserver from cyrus to dovecot. The new setup was using postfixadmin let the domain admins configure the hostet domains. To view the used quota in postfixadmin the usage of the quota dict backend is required. I have configured it according to the wiki but everytime I connect I get a sucessfully login and then every next command hangs. It seems to me, that the dict process itself is hanging. I even startet with a fresh mail box. The only way to login with my setup is to disable quota for the used protocol. My system is debian lenny based with dovecot 1.0.15 and PostgreSQL 8.3.7 as database server. My config is the following: # 1.0.15: /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S protocols: imaps pop3s managesieve listen: [::] ssl_cert_file: /etc/ssl/certs/server.crt ssl_key_file: /etc/ssl/private/server.key login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login login_executable(managesieve): /usr/lib/dovecot/managesieve-login login_greeting: Ready. first_valid_uid: 8 last_valid_uid: 8 mail_privileged_group: mail mail_location: maildir:/var/mail/%d/%n mail_debug: yes mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_executable(managesieve): /usr/lib/dovecot/managesieve mail_plugins(default): quota imap_quota acl mail_plugins(imap): quota imap_quota acl mail_plugins(pop3): quota mail_plugins(managesieve): mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 mail_plugin_dir(managesieve): /usr/lib/dovecot/modules/managesieve pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %v.%u pop3_uidl_format(managesieve): sieve_storage(default): sieve_storage(imap): sieve_storage(pop3): sieve_storage(managesieve): /var/mail/sieve/%d/%n sieve(default): sieve(imap): sieve(pop3): sieve(managesieve): /var/mail/sieve/%d/%n.sieve namespace: type: private inbox: yes auth default: user: dovecot-auth passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: sql args: /etc/dovecot/dovecot-sql.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 master: path: /var/run/dovecot/auth-master mode: 384 user: mail group: mail plugin: quota: dict:storage=10240 proxy::quota acl: vfile:/etc/dovecot/acls sieve: /var/mail/sieve/%d/%n.sieve dict: quota: pgsql:/etc/dovecot/dovecot-dict-quota.conf My /etc/dovecot/dovecot-dict-quota.conf: connect = host=localhost dbname=mail user=mail password=dovecot-passwort table = quota select_field = current where_field = path username_field = username My database table: CREATE TABLE quota ( username character varying(255) NOT NULL, path character varying(100) NOT NULL, "current" integer, CONSTRAINT quota_pkey PRIMARY KEY (username, path) ) WITH (OIDS=FALSE); ALTER TABLE quota OWNER TO mail; -- Trigger: mergequota on quota -- DROP TRIGGER mergequota ON quota; CREATE TRIGGER mergequota BEFORE INSERT ON quota FOR EACH ROW EXECUTE PROCEDURE merge_quota(); connect = host=localhost dbname=mail user=dovecot password=jianueyeePeev5o table = quota select_field = current where_field = path username_field = username My dovecot logfile with mail_debug=yes: Jul 20 21:06:17 skippy dovecot: Dovecot v1.0.15 starting up Jul 20 21:06:17 skippy dovecot: auth(default): pgsql: Connected to mail Jul 20 21:07:07 skippy dovecot: POP3(user(a)domain.tld): Loading modules from directory: /usr/lib/dovecot/modules/pop3 Jul 20 21:07:07 skippy dovecot: POP3(user(a)domain.tld): Module loaded: /usr/lib/dovecot/modules/pop3/lib10_quota_plugin.so Jul 20 21:07:07 skippy dovecot: POP3(user(a)domain.tld): Effective uid=8, gid=8 Jul 20 21:07:07 skippy dovecot: POP3(user(a)domain.tld): maildir: data=/var/mail/domain.tld/user Jul 20 21:07:07 skippy dovecot: POP3(user(a)domain.tld): maildir: root=/var/mail/domain.tld/user, index=/var/mail/domain.tld/user, control=, inbox= Jul 20 21:07:07 skippy dovecot: POP3(user(a)domain.tld): dict quota: uri = proxy::quota Jul 20 21:07:07 skippy dovecot: POP3(user(a)domain.tld): dict quota: byte limit = 52428800 Jul 20 21:07:07 skippy dovecot: POP3(user(a)domain.tld): dict quota: count limit = 0 Jul 20 21:07:07 skippy dovecot: pop3-login: Login: user=<user(a)domain.tld>, method=PLAIN, rip=::ffff:1.2.3.4, lip=::ffff:1.2.3.5, TLS Jul 20 21:07:07 skippy dovecot: dict: pgsql: Connected to mail Jul 20 21:07:07 skippy dovecot: dict: Timeout leak: 0x40e150 Jul 20 21:07:07 skippy dovecot: dict: WARNING: there is no transaction in progress I'm a little bit clueless because there is no significant output (even in strace).

[Dovecot] Filesystem size limitation?
by Tommy Ng 20 Jul '09

20 Jul '09

I'm new to dovecot, nice to meet you guys here. Referring to Redhat, 32bit Linux v5 GFS supports 16TB filesystem size while 64bit version supports 8 EB (1EB = 1024TB) size. Reference: http://www.redhat.com/rhel/compare/ My question is, any limitation on a single filesystem (Redhat GFS) that Dovecot can handle? or Dovecot depends only on the limitation of OS?

[Dovecot] Bug in Dovecot Managesieve or Horde ?
by Christian Felsing 20 Jul '09

20 Jul '09

Hello, there is a problem between Dovevot 1.2 Managesieve 0.11.7 and Horde webmail 1.2.2 (possibly also in 1.2.3) in imap4flags $ telnet localhost 2000 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. "IMPLEMENTATION" "dovecot" "SIEVE" "fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include body variables enotify environment" "SASL" "PLAIN LOGIN" "STARTTLS" "NOTIFY" "mailto" "VERSION" "1.0" OK "taunusstein.net imap4/pop3 ready." This shows imap4flags, Cyrus sieve shows imapflags instead that. Horde Ingos does not like that and complains about missing "imapflags". Two small patches in Horde code resolves that, but I do not know if that's the right way. cd webmail2/ingo/lib vi ./Script/sieve.php: function requires() { //return array('imapflags'); return array('imap4flags'); } vi ./tests/SieveTest.php: function testBlacklistMarker() { $bl = &new Ingo_Storage_blacklist(3); $bl->setBlacklist(array('spammer(a)example.com')); $bl->setBlacklistFolder(INGO_BLACKLIST_MARKER); $this->store($bl); //$this->assertScript('require "imapflags"; $this->assertScript('require "imap4flags"; if address :all :comparator "i;ascii-casemap" :is ["From", "Sender", "Resent-From"] "spammer(a)example.com" { addflag "\\\\Deleted"; keep; removeflag "\\\\Deleted"; stop; }'); } After that, Horde Ingo likes Dovecot mailsieve. Is it a bug of mailsieve ? Regards Christian

[Dovecot] dovecot 1.2rc5 fails to authenticate user via GSSAPI
by Michal Hlavinka 20 Jul '09

20 Jul '09

Hi, we're facing problem where dovecot 1.2rc5 is not able to authenticate user via gssapi. (I'm forwarding information from red hat's bugzilla) Steps to reproduce: 1. Install dovecot with kerberos support, create mailboxes for the client 2. Get initial credentials on client side 3. Attempt to log in via dovecot using gssapi -> login failed Client side 1. Email client displays: "[AUTHENTICATIONFAILED] Authentication failed." 2. klist before login shows: Valid starting Expires Service principal 06/18/09 20:01:01 06/19/09 20:01:01 krbtgt/realm@realm 3. klist after login attempt shows: Valid starting Expires Service principal 06/18/09 20:01:01 06/19/09 20:01:01 krbtgt/realm@realm 06/18/09 20:01:28 06/19/09 20:01:01 imap/mail.domain@realm Server side 1. /var/log/maillog: dovecot: auth(default): gssapi(user,192.168.0.1): authn_name not authorized dovecot: imap-login: Aborted login (auth failed, 1 attempts): user=<user>, method=GSSAPI, rip=192.168.0.1, lip=192.168.0.2, TLS ---------------- It is possible for the same user to login via other mechanisms. The issue reproduced with different email clients. Evolution and a custom java-based client were attempted. example of dovecot.conf: protocols = imap mail_location = maildir:/home/virtual/%u/Maildir protocol imap { } auth_krb5_keytab=/etc/dovecot.keytab auth default { mechanisms = gssapi userdb static { args = uid=vmail gid=vmail home=/home/virtual/%u } } ------------------------- Exactly the same dovecot setup was working just fine with dovecot 1.1 series. Authentication using kinit works just fine and kerberos infrastructure is functioning well as I use kerberos auth for other services like apache and ssh successfully. /var/log/maillog with using auth_debug=yes can be found here: https://bugzilla.redhat.com/attachment.cgi?id=348710 Regards, Michal Hlavinka

[Dovecot] RFC: Different quota for dovecot and deliver
by Philipp Marek 20 Jul '09

20 Jul '09

Hello everybody, I've been with this question in IRC the last days, but no solution was found. So I looked into the sources, and came up with the attached (untested, not even compiled) patch against 1.2.1. Rationale ----------- I'd like to bounce on the external side, which is quite easy if the quota is stored in a SQL database; then eg. postfix can directly query it, and reject accordingly without doing any real work. Now, as discussed some time ago on the postfix list (cannot find it anymore, sorry), it would be best to *not* bounce internally, ie. when the mail is delivered in the mailbox, but to allow a small bit of over-usage instead. Thoughts ---------- Why don't we simply set the value seen by postfix down a bit? I don't think that this is the correct solution; if the difference between these two values is smaller than the allowed mail size we'd get internal bounces again. (And we wouldn't allow to *get* the amount of mail, btw, only to use it via COPY.) There are more complicated schemes, like putting a slightly higher quota in the configuration, and subtracting a bit in postfix again. I wouldn't see that as aesthetical, too. Furthermore all such schemes have the problem of being unstable - larger mails get (internally) rejected earlier than small ones. Wanted behaviour ------------------ What I'd like to achieve is that postfix uses the trigger value from the Database as well, but that deliver allows a small bit more - say 5, 10, or 20MB. Then one incoming mail simply makes the quota go over the defined limit; now postfix no longer accepts mail, but the incoming queue (amavis etc.) can be drained - at least if there's not some big hiccup in queue processing, and that's why I'd like to use a *different* quota, and not simply *none* (for deliver). Idea to solve this -------------------- The idea is that in the SQL configuration the name of an environment variable can be given to the SELECT query; this name, and the value of the environment variable, are used as an additional WHERE constraint. It would be much nicer if a stored procedure could be called with parameters (like Postfix allows), but that would mean a fair bit of change to dovecot. (And in Postgres at least the query could be rewritten with rules - but that's not that nice, either.) I've now looked into the sources, and tried to sketch the basic change that I imagine; please see the attached patch. Would something like that be acceptable? I thought for some time whether the additional query should use the filename part of the executable; then similar things could be done. But as this is a bit more general I settled for the environment variable. Thank you for all answers. Regards, Phil

[Dovecot] dovecot as lda : nothing happens
by denis 19 Jul '09

19 Jul '09

Hi, On debian lenny, I try to configure my setup (with Postfix virtual domains) to use dovecot as lda. I adjusted my settings to postfix and dovecot, but nothing happens... The dovecot.log is always empty and nothing seems to change, as if it had no effect. Here are my changes, if someone sees what would be problematic ...

[Dovecot] Changed URLs of the automated Debian repositories
by Stephan Bosch 19 Jul '09

19 Jul '09

Hi, Due to the advent of Dovecot v2.0, I restructured the automated Debian package builder to build packages for v2.0 as well. Those of you using the automated repositories should change their /etc/apt/sources.list files as follows: Dovecot v1.1 for Debian Testing (binary and source): deb http://xi.rename-it.nl/debian/ testing-auto/dovecot-1.1 main deb-src http://xi.rename-it.nl/debian/ testing-auto/dovecot-1.1 main Dovecot v1.2 for Debian Testing (binary and source): deb http://xi.rename-it.nl/debian/ testing-auto/dovecot-1.2 main deb-src http://xi.rename-it.nl/debian/ testing-auto/dovecot-1.2 main Dovecot v2.0 for Debian Testing (binary and source): deb http://xi.rename-it.nl/debian/ testing-auto/dovecot-2.0 main deb-src http://xi.rename-it.nl/debian/ testing-auto/dovecot-2.0 main Dovecot v2.0 ManageSieve and Sieve need quite a few changes yet to become fully functional. ManageSieve is even still pretty much broken for the new Dovecot version. This means that Dovecot v2.0 (at least with respect to the Sieve support) is not quite ready for testing. That is also why the the v2.0 repository is not mentioned in the wiki. Regards, -- Stephan Bosch stephan(a)rename-it.nl

[Dovecot] Changed URL of the Sieve Mercurial repository.
by Stephan Bosch 19 Jul '09

19 Jul '09

Hi, I've changed the name of the Sieve Mercurial repository form dovecot-libsieve to dovecot-1.2-sieve, to signify the Dovecot version it applies to. The URL thus looks as follows: http://hg.rename-it.nl/dovecot-1.2-sieve Note that there are already dovecot-2.0-sieve and dovecot-2.0-managesieve repositories, but these are still somewhat broken in multiple ways and I wouldn't call these ready for testing yet.

[Dovecot] dsync - one or two ways?
by Timo Sirainen 18 Jul '09

18 Jul '09

dsync in Dovecot v2.0 tree is a new utility for syncing a mailbox in two locations. Some things it can be used for: - Initially transfer a mailbox to another server via SSH - A faster sync done to an existing mailbox, sending only changes - A superfast sync based on modification sequences. - Source and destination mailboxes can use different formats (convert-tool will be history) dsync can handle all kinds of conflicts in mailboxes, handle mailbox deletions, renames, etc. So it's safe to sync even if both source and destination mailboxes have had all kinds of changes. Now, the question is: Does anyone want dsync to only sync changes from source to destination, instead of doing a full two-way sync? I think in typical cases where you'd think you would want only one-way sync are also the cases where there's no changes coming the other way in any case.

[Dovecot] SMTP Auth Issue for non /etc/passwd accounts
by Mark R. Baith 17 Jul '09

17 Jul '09

Folks - With Dovecot 1.0.7, we're seemingly unable to authenticate users for out-going SMTP access who are not residing directly within the main system passwd/shadow files. (I.e. the users seeded within our non-system "dovecot" userdbs & passwd files have no "smtp-auth" joy! (Ye olde "Relaying denied. Proper authentication required") I've mucked around with this from several different angles and clearly saslauthd is the sticking point in terms of "locking-in" on the /etc system files ONLY for smtp-auth. Our defined dovecot user/passwd files are entirely ignored. Can anyone provide a direction regarding the appropriate smtp-auth in-road? Thanks, -M Regards, M

[Dovecot] Question regarding layout.
by Johan Hendriks 17 Jul '09

17 Jul '09

Hello all. I have a question regarding my mail flow. We have some users who are in a mail group (alias), and these alias receives a lot of attached documents. So i have the document in all the mailboxes of the alias. If the attached document is 2MB and that is not rare, i have 10 times 2 MB on my mail server. Is there a way to tackle this. Maybe by making the alias a mailbox itself and give other users acces or are there other options. Also i have very lame and lazy users. They refuse to clean thrash cans (i asked about that earlier,and got that tackled through the expire plugin.),also the do not remove old mail not even reading it. So is there also a option to remove mail that is not been opened, and is older than xx days or weeks.

[Dovecot] Can Dovecot Proxy GMail?
by Paul Carter-Brown 16 Jul '09

16 Jul '09

Hi, We are using gmail (google apps) across our company with most users using outlook (windoze) or evolution (linux) and imap/pop based on user preference. We are having issues in that our internet links are fairly slow and when users download mails they get frustrated with the time it takes and often get timeouts and issues where outlook fails to fetch a mail yet gmail thinks it was retrieved - users then complain of "missing" emails. Is there a way that we could use dovecot (or similar?) to act as an imap "proxy" and users connect to dovecot while dovecot connects to gmail? Thanks Paul

[Dovecot] Expire plugin - where to start?
by Frank Leonhardt 15 Jul '09

15 Jul '09

I'm running Dovecot 1.1.3 on FreeBSD 7.0 with procmail 3.22 sorting the output of Spamassassin. Just for me and a few friends. I didn't like the ageing 'standard' IMAP implementation so I thought I'd give Dovecot a try and it's really impressive. However, I'm a complete newbie to its inner workings. Spamassassin is able to find plenty to chew on so the "Probable spam" mbox (note) fills up fast. I obviously want to zap the old stuff in there automatically. It seems to me that the expire plugin is the thing I need BUT reading the documentation: http://wiki.dovecot.org/Plugins/Expire Leaves me to scared to try anything. It's all working and I don't want to break it or delete anyone's mail. The problem that the wiki isn't accurate to the version I'm running. For example /usr/libexec/dovecot/expire-tool.sh doesn't exist. Okay, this isn't Linux, and there's something likely where I'd expect it on BSD (/usr/local/...) - but it's a binary, not a shell script. It may be a direct replacement AFAIK, but it may not. I've been reading the old mailing list about problems with 1.2 and this reinforces the feeling that the wiki is out-of-sync. Am I being paranoid? Possibly, but I don't want to be posting a "Help! I've wrecked my config and deleted all my friend's mail" type message. (Okay, I'd take a backup first). So could some kind person point me at the latest documentation? Thanks, Frank.

[Dovecot] multiple authentication mechanisms/passwords for same account
by Tapani Tarvainen 15 Jul '09

15 Jul '09

This may be trivial but reading the documentation I can't find a clear answer: If multiple authentication mechanisms (or multiple databases for one) are defined, does it allow one user account to have several (at least two) alternative passwords (so that any of them would work)? Or does it first map an account to a fixed authentication mechanism/password and if it fails, others won't be tried? -- Tapani Tarvainen

[Dovecot] v3.0 architecture
by Timo Sirainen 15 Jul '09

15 Jul '09

I just had a thought. It's probably going to be too big of a change for v2.0, so something to think about for v3.0: Supporting multiple UIDs is difficult. Currently expire-tool and v2.0's LMTP server are implemented in a way that it's always running as root and only temporarily dropping privileges. So any security hole in there gives the attacker root privileges. Not very nice. With a single UID it's possible (or will be) to just use that one UID for the process without running as root. User sharing mailboxes to another user with different UID is even more difficult. Currently the only practical way to implement this is to assign read-write permissions to some group and have all mail files owned by that group. Not very nice. Sharing mailboxes between users located in different servers is impossible if the disk isn't somehow shared. All of these can be solved the same way: 1. imap, pop3, lmtp, etc. processes will be running without any privileges, very much like imap/pop3-login nowadays. Nobody-chrooted to empty directory. 2. Create storage processes that are started as needed. They can be configured in different security/performance settings: One storage process per user, one storage process per UID, setuid-root style shared storage process for multiple UIDs. 3. Mail processes talk to storage processes via some protocol. They can talk via UNIX socket or TCP/IP. If an existing connection can't handle the target UID, a new connection is made that either reuses an existing storage proces or creates a new one. 4. IMAP can finally implement truly simultaneously running queries (where it makes sense) by creating more storage processes if existing ones are busy handling longer-running commands. This also allows using the same storage process for multiple simultaneous IMAP connections and mail deliveries (and etc). The storage processes can also hang around and keep mailboxes open after all connections have closed it (dynamically figured out when it makes sense) to handle webmail clients that create lots of short-living connections or POP3 clients who poll for new mail every minute. The big problem is what the protocol should be. Use some existing RPC protocol? It should be something extensible so that a plugin in imap process can talk to a plugin in storage process, without the base processes knowing anything about the details (e.g. imap-quota plugin asking quota usage from storage's quota plugin). In any case the client side API should be asynchronous. That can make it annoyingly difficult to use though. Wonder if I could switch to erlang or something for the imap/pop3 processes :)

[Dovecot] Sieve problem: No vacation message when mail is addressed to an alias of the mailbox.
by M. Bobkiewicz 15 Jul '09

15 Jul '09

Hi, I?m facing here a wierd problem: We have a vacation messaging system using sieve. When activated the system forwards incomming messages to a given address and sents an out of office reply to the sender. This works like a charm when the mail is addressed to mailbox@domain. When the incomming mail ist addressed to alias.to.mailbox@domain the mail is delivered to the mailbox, it is forwarded to the given reciepient but there is no auto reply going out to the sender! Our setup: CentOS 5.2 + postfix 2.5.6 + dovecot 1.1.11 with domain and accounts stored in a mysql database. The script: require ["fileinto", "vacation"]; redirect "mailbox2@domain"; keep; vacation :days 1 :subject "Out of Office reply" " The auto reply text. "; Any advice is welcome, Best regards, Mike

Apart from that, it would be very useful if wasn't hard- coded like that.

[Dovecot] getting Apple Mail and dovecot/IMAP to co-operate
by Jim Reid 13 Jul '09

13 Jul '09

Hi. I've been fighting a losing battle to get Apple Mail and dovecot to play nice. When dovecot is told to use mbox-style mailboxes, it's not possible to create child mailboxes. Apple Mail whines "The IMAP command “CREATE” failed with server error: Mailbox doesn't allow inferior mailboxes.". I've looked through the documentation, the wiki and searched the mail archives without finding a solution. Can anyone help? I've tried (and failed) to get a hybrid maildir/mbox setup to work like that shown on http://wiki.dovecot.org/Namespaces. When that gets plugged into dovecot.conf, Apple Mail blocks, with the Activity window saying "waiting for login" or something like that, even though a valid imaps connection and login has been established. There's nothing getting logged by dovecote for both of these problems, even when syslog is turned all the way to debug priority. Here's the current configuration info: shaun# dovecot -n # 1.1.16: /usr/local/etc/dovecot.conf # OS: FreeBSD 7.2-RELEASE amd64 ufs base_dir: /var/run/dovecot/ syslog_facility: local4 protocols: imaps listen: *, [::] ssl_cert_file: /usr/local/etc/ssl/certs/dovecot.pem ssl_key_file: /usr/local/etc/ssl/private/dovecot.pem ssl_cipher_list: ALL:!LOW:!SSLv2 login_dir: /var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login login_max_processes_count: 8 login_max_connections: 32 max_mail_processes: 32 mail_privileged_group: mail mail_location: mbox:/mail/imap/%u:INBOX=/var/mail/%u mail_debug: yes mbox_write_locks: fcntl auth default: mechanisms: cram-md5 verbose: yes debug: yes passdb: driver: pam passdb: driver: passwd-file args: /usr/local/etc/dovecot-md5 userdb: driver: passwd shaun# dovecot --version 1.1.16

[Dovecot] Possible fix to an old Thunderbird related problem
by Marc Perkel 13 Jul '09

13 Jul '09

I think I might have finally fixed it. The problem was that the max_cached_connections in Thunderbird defaults to 25 and I had login process count set to 10. I think raising it to 25 ill fix it. Just posting this in case others are having this problem. What was happening was that the message counts were increasing but the messages didn't show up in the list. Or messages would appear to be empty. Restarting Dovecot or restarting Thunderbird fixes the problem temporarily. I'm hoping this annoyance will go away now.

by Timo Sirainen 13 Jul '09

13 Jul '09

http://dovecot.org/releases/1.2/dovecot-1.2.1.tar.gz http://dovecot.org/releases/1.2/dovecot-1.2.1.tar.gz.sig Mainly fixes to some issues found by people when upgrading to v1.2.0. * GSSAPI: Changed logging levels and improved the messages. Changed the way cross-realm authentication handling is done, hopefully it's working now for everyone. * imap/pop3 logins now fail if home directory path is relative. v1.2.0 deliver was already failing with these and they could have caused problems even with v1.1. * IMAP: Custom authentication failure messages are now prefixed with [ALERT] to get more clients to actually show them. + Improved some error messages. - pop3: AUTH PLAIN was broken when SASL initial response wasn't given. - mbox: New mailboxes were created with UIDVALIDITY 1. - quota-fs was defaulting to group quota instead of user quota. - Fixed ACLs to work with mbox. - Fixed fchmod(-1, -1) errors with BSDs - convert plugin / convert-tool: Fixed changing hierarchy separators in mailbox names when alt_hierarchy_char isn't set.

[Dovecot] Released Sieve v0.1.8 and ManageSieve v0.11.7 for Dovecot v1.2.1
by Stephan Bosch 13 Jul '09

13 Jul '09

Hello Dovecot users, The recent Dovecot v1.2.1 release broke ManageSieve compilation. Today, I release new packages to fix this and additionally a few bugs are resolved. Changelog Sieve v0.1.8: - Fixed AIX compile problem. For portability, the typeof operator is not used anymore. + Added partial support for the deprecated notify extension. However, it turns out that the implementation provided by cmusieve is even older (2001), meaning that this is currently not backwards compatible with cmusieve. Should be fixed in next release. Changelog ManageSieve v0.11.7: * Adjusted to changes in the Dovecot login API. This release now depends on Dovecot v1.2.1 or newer. * Incorporated various small changes in IMAP into ManageSieve. This includes properly enabling the generation of core dumps. - The previous release implicitly resolved the FreeBSD script truncation error. This release adds a small correction to the code that detects the truncation. - Fixed panic occurring when many errors are produced by the Sieve compiler (bug found by Pascal Volk). - Fixed memory leak in the PUTSCRIPT command. (ManageSieve patch) - Forgot to add the managesieve_logout_format setting to the config file. Now it works (bug reported by Pascal Volk). -- The releases are available as follows: Sieve: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.8.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.8.tar.gz.sig ManageSieve (package + patch): http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.7.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.7.tar.gz.s… http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.1-managesieve-0.11.7.diff.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.1-managesieve-0.11.7.diff.g… -- Have fun testing the new releases and don't hesitate to notify me when there are problems.

Hello, I try to get per-mailbox-ACLs on dovecot. So, I've modded dovecot.conf: protocol imap { mail_plugins = acl } and plugin { acl = vfile } When I telnet to dovecot an try the command "capability" there is nothing about acl. I need acl for "open-xchange" so I can share Mailboxes over the webinterface.

[Dovecot] problem with convert-tool: "Invalid mailbox name"

Hello everyone. I'm having a problem with convert-tool while trying to convert mbox folders to maildir. I'm running dovecot-1.1.16 on Centos 5.3 If the user has subfolders, convert-tool fails saying: "Mailbox conversion: Couldn't create mailbox sub/folder3: Invalid mailbox name" However, if I ran the convert-tool with the same arguments and same folders with dovecot 1.1.11 on Ubuntu 9.04 it works fine. Any pointers for troubleshooting this? Thanks in advance, Ezequiel

Description of problem: Hello, I am having problems with Dovecot not delivering 'big' emails. Small email with 1-2 kb text delivered fine. If the message about 200kb long or more it freezes. I am also getting "copy: i_stream_read() failed: Permission denied" erros in Dovecot log files.

[Dovecot] non-lowercase usernames

Should I just make Dovecot lowercase usernames by default in v2.0? auth_username_format = %Lu Does anyone actually want to use non-lowercase usernames?

[Dovecot] Sieve on full mailbox
by ian＠comtek.co.uk 10 Jul '09

10 Jul '09

Hi, We are using dovecot with "mail_plugins = cmusieve". I have Avelsieve in SquirrelMail for users to interact with it. Is there any way I can allow users to run their sieve script on an entire mailbox? While the normal case of having messages filtered as they are delivered to the Maildir makes sense it would be useful for a few users to be able to apply their rules to every message on a one-off basis. If there is a binary which will do this job? I could adapt the SquirrelMail interface to invoke it with appropriate arguments. Thanks, Ian

[Dovecot] Dovecot delivering mail in the wrong directory location
by Tjerk Wolterink 10 Jul '09

10 Jul '09

Hello everybody,my new server is setup with postfix as a MTA and dovecot as a MDA, mysql is used as a user db, and postfixadmin is used to setup accounts. Login via pop works fine, also sending via smtp works fine. HOWEVER: when i sent a mail by hand via smtp it is delivered in the wrong directory. For example for test(a)xdatasystem.com i have the following directory: /home/vmail/xdatasystem.com/test However the mail is delivered to this directory: /home/vmail/test(a)xdatasystem.com/ I cannot figure this out as dovecot is correctly configured. ( think) Here is the important part of my dovecot.conf (sorry for the indents): === DOVECOT.CONF === *disable_plaintext_auth = no* *log_timestamp = "%Y-%m-%d %H:%M:%S "* *mail_location = maildir:/home/vmail/%d/%n/Maildir* *mail_access_groups = vmail* *first_valid_uid = 100* *first_valid_gid = 100* * * *protocol imap {* *}* * * *protocol pop3 {* *pop3_uidl_format = %08Xu%08Xv* *}* *auth default {* *mechanisms = digest-md5 plain* *passdb sql {* *args = /etc/dovecot/dovecot-sql.conf* *}* *#userdb sql {* *#args = /etc/dovecot/dovecot-sql.conf* *#}* * * *userdb static {* *args = uid=vmail gid=vmail home=/home/vmail/%d/%n* * }* * * *user = root* *}* === DOVECOT.CONF === Has anybody a clue?

[Dovecot] Optimal quota method for SQL
by Tom Sommer 10 Jul '09

10 Jul '09

Hi, I just installed 1.2.0 and I'm gonna set up some quota on my vitual users. I' ve got dovecot set up as LDA, and currently I'm using the dict-mysql method described for 1.2.0, but it's not really working at all. Am I correct in assuming that with this method I can define the quota limit in my dict (sql field)? This is my current config: dict { quotadict = mysql:/etc/dovecot-dict-sql.conf } plugin { quota = dict:user::proxy::quotadict quota_rule = *:storage=0:messages=0 } protocol lda { mail_plugins = quota ..... } I want quota to be disabled unless otherwise specified in my SQL database. // Tom

[Dovecot] Managesieve fails to retrieve scripts > 8kB on Dovecot 1.1.16
by John Marshall 10 Jul '09

10 Jul '09

After some help with debugging tips on #dovecot, I have established that a sieve script on Dovecot 1.1.16 has to be less than 8kB in order to be retrieved by a managesieve client. I have been using managesieve for about 6 months over as many 1.1.n versions of dovecot as have been around during that time and hit this problem when I upgraded to Dovecot 1.1.16. I have gone back to Dovecot 1.1.15 and can once again manage my 9kB sieve script remotely. Symptoms were that managesieve login was OK but instead of displaying my sieve script, the script editing window was empty. After 30 seconds the client gave me a timeout message. If I entered a small script in the empty client edit window and saved it, the new, small script was saved to the server and became active. I could then successfully retrieve and edit that small script. I tried hacking a few lines at a time out of my 9kB script (locally on the server). When it was down to 8.4KB I still couldn't get it through managesieve. The next hack took it down to 7.7kB and I could get that through managesieve. So, I'm guessing there's a magic 8192 number in there somewhere - perhaps a buffer? Server dovecot 1.1.16 dovecot-sieve 1.1.6 dovecot-managesieve 0.10.6 FreeBSD 7.2 Client Thunderbird 2.0.21 Sieve 0.1.6 A special thanks to all who write this stuff: it's great! -- John Marshall

[Dovecot] First V1.2 compile questions
by Stewart Dean 09 Jul '09

09 Jul '09

1) I see that the --without-pop3d option has gone away. What does this imply, i.e why was that done? Is there some other way that you now avoid compiling the POP code? Are there any other discontinued options? 2) There was some talk a while back about changing how and where the plugins were to be built and their code located. Was this implemented? If so, is there any doc on it? -- ==== Once upon a time, the Internet was a friendly, neighbors-helping-neighbors small town, and no one locked their doors. Now it's like an apartment in Bed-Stuy: you need three heavy duty pick-proof locks, one of those braces that goes from the lock to the floor, and bars on the windows.... ==== Stewart Dean, Unix System Admin, Bard College, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035

[Dovecot] Long delay checking mail with POP w/plain auth
by david hardy 09 Jul '09

09 Jul '09

I just switched from UW-IMAP to dovecot, and it all went smooth, except now I get a 4-5 second delay after connecting to the POP3 server (IMAP is fine). If I switch to auth "mechanisms=login", it is instantaneous - the delay is gone. In my logs I am getting : Jul 9 12:21:03 haleakala dovecot: auth(default): client in: AUTH 1 PLAIN service=pop3 lip=205.168.236. rip=205.168.236. lport=110 rport=62500 resp=<hidden> Jul 9 12:21:03 haleakala dovecot: auth(default): plain(?,205.168.236.): invalid input Jul 9 12:21:03 haleakala dovecot: auth(default): new auth connection: pid=2750 Jul 9 12:21:03 haleakala dovecot: auth(default): client out: FAIL 1 and then it tries again apparently, and succeeds: Jul 9 12:21:08 haleakala dovecot: auth(default): client in: AUTH 2 PLAIN service=pop3 lip=205.168.236. rip=205.168.236. lport=110 rport=62500 resp=<hidden> Jul 9 12:21:08 haleakala dovecot: auth-worker(default): pam(divad,205.168.236.): lookup service=dovecot Jul 9 12:21:08 haleakala dovecot: auth-worker(default): pam(divad,205.168.236.): #1/1 style=1 msg=Password: Jul 9 12:21:08 haleakala dovecot: auth(default): client out: OK 2 user=divad Jul 9 12:21:08 haleakala dovecot: auth(default): master in: REQUEST 217 2552 2 Jul 9 12:21:08 haleakala dovecot: auth(default): passwd(divad,205.168.236.): lookup Jul 9 12:21:08 haleakala dovecot: auth(default): master out: USER 217 divad system_groups_user=divad uid= gid= home=/home/david Jul 9 12:21:08 haleakala dovecot: pop3-login: Login: user=<divad>, method=PLAIN, rip=205.168.236., lip=205.168.236.

[Dovecot] Problem with 1.2 and sieve: failed with unsuccessful implicit keep
by Julien Danjou 08 Jul '09

08 Jul '09

Hi, First, thanks for this awesome piece of software. I've just upgraded to latest dovecot, aka 1.2. I've a problem. I've started using Sieve, and everything works fine, I already received a thousand of mails without any problem. However, there's one mail which is stuck in the postfix queue because of that: Jul 8 18:47:51 prometheus dovecot: deliver(jd(a)danjou.info): mkdir_parents_chown(danjou.info/jd/) failed: Permission denied (euid=8(mail) egid=8(mail)) Jul 8 18:47:51 prometheus dovecot: deliver(jd(a)danjou.info): copy: i_stream_read() failed: No such file or directory Jul 8 18:47:51 prometheus dovecot: deliver(jd(a)danjou.info): sieve: msgid=? <1186f9b5-0529-4622-8f4a-58462f9a4bcb(a)svr-exchange.siege.ldlc.com>: failed to store into mailbox 'INBOX': Internal error occurred.

[Dovecot] System users, mbox format and global ACLs
by Axel Luttgens 08 Jul '09

08 Jul '09

I need some help here... ;-) I'm experimenting with global ACLs, but just fail to understand very basic behaviors. So, before digging into the source code, I would really be delighted if someone could immediately point a mistake I'm making and miserably overlooking. The output of dovecot -n is provided at the end of this email. Just in case, conforming to the suggestion made in http://wiki.dovecot.org/ACL , I've specified a CONTROL directory; but I get a similar behavior without it. As far as the acl plugin is concerned, I've just specified a directory for global ACLs; whether that directory is populated or not doesn't seem to have an impact on the observed behavior. Here's the structure of the test user's home directory: total 0 drwx------ 4 testuser people 136 26 jui 13:52 . drwxr-xr-x 3 root admin 102 19 mai 16:56 .. drwxr-xr-x 4 testuser people 136 28 jui 17:09 _mailboxes drwxr-xr-x 2 testuser people 68 28 jui 17:07 _mboxesctrl ./_mailboxes: total 96 drwxr-xr-x 4 testuser people 136 28 jui 17:09 . drwx------ 4 testuser people 136 26 jui 13:52 .. drwx------ 3 testuser people 102 19 mai 17:02 .imap -rw------- 1 testuser people 48685 25 jui 16:58 inbox ./_mailboxes/.imap: total 0 drwx------ 3 testuser people 102 19 mai 17:02 . drwxr-xr-x 4 testuser people 136 28 jui 17:09 .. drwx------ 5 testuser people 170 23 jui 18:02 INBOX ./_mailboxes/.imap/INBOX: total 88 drwx------ 5 testuser people 170 23 jui 18:02 . drwx------ 3 testuser people 102 19 mai 17:02 .. -rw------- 1 testuser people 1376 23 jui 18:02 dovecot.index -rw------- 1 testuser people 26624 28 jui 10:23 dovecot.index.cache -rw-rw-rw- 1 testuser people 10284 25 jui 17:57 dovecot.index.log ./_mboxesctrl: total 0 drwxr-xr-x 2 testuser people 68 28 jui 17:07 . drwx------ 4 testuser people 136 26 jui 13:52 .. I've tried various combinations of permissions and ownership, again without any obvious influence. The manual creation of directory ~/_mboxesctrl/.imap doesn't seem to be more helpful. So, let's go to the heart of my "problem": # telnet 127.0.0.1 imap Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE AUTH=PLAIN] Dovecot ready. a1 login testuser ****** a1 OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE SORT THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT IDLE CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH] Logged in a2 list "" * * LIST (\NoInferiors \UnMarked) "/" "dovecot-acl-list" * LIST (\HasNoChildren \UnMarked) "/" "INBOX" a2 OK List completed. a3 logout * BYE Logging out a3 OK Logout completed. Connection closed by foreign host. And indeed, a file named "dovecot-acl-list" has now been created under the _mailboxes directory: ./_mailboxes: total 96 drwxr-xr-x 5 testuser people 170 28 jui 17:11 . drwx------ 4 testuser people 136 26 jui 13:52 .. drwx------ 3 testuser people 102 19 mai 17:02 .imap -rw-r--r-- 1 testuser people 0 28 jui 17:11 dovecot-acl-list -rw------- 1 testuser people 48685 25 jui 16:58 inbox This is the only file to have been created consecutively to the telnet session. Is such a file supposed to be created there? If yes, why? I would have tended to believe that it is more a server internal matter than a name having to appear in the namespace. More generally, is such a file supposed to be created at all? After all, the configuration doesn't explicitely mention per-mailbox ACLs at all... Anyway, this is what gets written in mail.log for the whole telnet session: dovecot[82305]: auth(default): new auth connection: pid=82374 dovecot[82305]: auth(default): client in: AUTH 1 PLAIN service=imap secured lip=127.0.0.1 rip=127.0.0.1 lport=143 rport=49879 resp=<hidden> dovecot[82305]: auth-worker(default): pam(testuser,127.0.0.1): lookup service=imap dovecot[82305]: auth-worker(default): pam(testuser,127.0.0.1): #1/1 style=1 msg=Password: dovecot[82305]: auth(default): client out: OK 1 user=testuser dovecot[82305]: auth(default): master in: REQUEST 8 82327 1 dovecot[82305]: auth(default): passwd(testuser,127.0.0.1): lookup dovecot[82305]: auth(default): master out: USER 8 testuser system_groups_user=testuser uid=2001 gid=2001 home=/Volumes/ALMbpSpare/ People/a/testuser dovecot[82305]: imap-login: Login: user=<testuser>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured dovecot[82305]: IMAP(testuser): Loading modules from directory: /usr/ local/dovecot-1.2.rc7/lib/dovecot/imap dovecot[82305]: IMAP(testuser): Module loaded: /usr/local/ dovecot-1.2.rc7/lib/dovecot/imap/lib01_acl_plugin.so dovecot[82305]: IMAP(testuser): Effective uid=2001, gid=2001, home=/ Volumes/ALMbpSpare/People/a/testuser dovecot[82305]: IMAP(testuser): acl: No acl_shared_dict setting - shared mailbox listing is disabled dovecot[82305]: IMAP(testuser): mbox: data=~/_mailboxes:INBOX=~/ _mailboxes/inbox:CONTROL=~/_mboxesctrl dovecot[82305]: IMAP(testuser): fs: root=/Volumes/ALMbpSpare/People/a/ testuser/_mailboxes, index=, control=/Volumes/ALMbpSpare/People/a/ testuser/_mboxesctrl, inbox=/Volumes/ALMbpSpare/People/a/testuser/ _mailboxes/inbox dovecot[82305]: IMAP(testuser): acl: initializing backend with data: vfile:/usr/local/etc/dovecot-acls dovecot[82305]: IMAP(testuser): acl: acl username = testuser dovecot[82305]: IMAP(testuser): acl: owner = 1 dovecot[82305]: IMAP(testuser): acl vfile: Global ACL directory: /usr/ local/etc/dovecot-acls dovecot[82305]: IMAP(testuser): acl vfile: file /usr/local/etc/ dovecot-acls//.DEFAULT not found dovecot[82305]: IMAP(testuser): Namespace : Using permissions from / Volumes/ALMbpSpare/People/a/testuser/_mailboxes: mode=0755 gid=-1 dovecot[82305]: IMAP(testuser): acl vfile: file /usr/local/etc/ dovecot-acls/.temp.ALMbp.local.82375.f9efcb24711711fb not found dovecot[82305]: IMAP(testuser): acl vfile: file /Volumes/ALMbpSpare/ People/a/testuser/_mboxesctrl/.imap/.temp.ALMbp.local. 82375.f9efcb24711711fb/dovecot-acl not found dovecot[82305]: IMAP(testuser): acl vfile: file /usr/local/etc/ dovecot-acls/INBOX not found dovecot[82305]: IMAP(testuser): acl vfile: file /Volumes/ALMbpSpare/ People/a/testuser/_mboxesctrl/.imap/INBOX/dovecot-acl not found dovecot[82305]: IMAP(testuser): acl vfile: file /usr/local/etc/ dovecot-acls/dovecot-acl-list not found dovecot[82305]: IMAP(testuser): acl vfile: file /Volumes/ALMbpSpare/ People/a/testuser/_mboxesctrl/.imap/dovecot-acl-list/dovecot-acl not found dovecot[82305]: IMAP(testuser): Disconnected: Logged out bytes=23/431 Why does the server seem to expect to find a temp file under ~/ _mboxesctrl/.imap?

[Dovecot] Problem with sieve and german umlauts
by M. Bobkiewicz 08 Jul '09

08 Jul '09

Dear list, I?m running a postfix (2.5.6) / Dovecot (1.1.11) on a Centos 5.2 box. I?ve written a small gui application to simply create Out of Office replys with sieve. The resulting code did work with maildrop without any problems. Now sieve fails when it meets any german umlauts like ä or ü. It just stops compiling the scripts and complains about the missing "};". A simple fix is to just replace the umlauts, but that doesn?t meet the expectations of my users. Is there any escape code I could use or any way to place the mail text outside the script? Best regards, Mike

During the whole telnet session, both files "new1" and "new2" remained empty (i.e. no pseudo-message written to them), no uidvalidity-related helper file seems to have been created and no uidvalidity-related function seems to have been called. And clearly, both mailboxes "new1" and "new2" have received the same UIDVALIDITY. Those UIDVALIDITYs appear to be persistent; messages may be added to and deleted from those mailboxes, those mailboxes may be renamed... their UIDVALIDITY remain unchanged and equal to 1. In fact, any additional mailbox is created with that unique and persistent UIDVALIDITY of 1. Is this supposed to behave that way?

[Dovecot] Dovecot 1.2rc7 / Sieve Plugin problem / Namespaces
by reg9009 08 Jul '09

08 Jul '09

Hi, I've got a problem with Dovecot 1.2rc7 and a Sieve script which should store eMails in a subfolder. It always fails with Jun 28 14:56:43 deliver(): Error: sieve: msgid=<4A47687D.30903(a)some.domain>: failed to store into mailbox '': Invalid mailbox name Jun 28 14:56:43 deliver(): Error: sieve: script /home/dovecot/sieve/info/dovecot.sieve failed with unsuccessful implicit keep This is with dovecot-libsieve. Same happens with cmusieve, though the message is slightly different: Jun 28 14:55:39 deliver(): Info: cmusieve: Executing script /home/dovecot/sieve/info/dovecot.sievec Jun 28 14:55:39 deliver(): Info: sieve runtime error: Keep: Generic Error Sieve script: if header :comparator "i;ascii-casemap" :contains "X-Spam-Level" "*****" { fileinto "INBOX/Junk"; stop; } I tried "INBOX.Junk", "Junk", etc., but no success. Namespace section in dovecot.conf: namespace private { separator = / prefix = INBOX/ inbox = yes #hidden = yes #list=yes } Same configuration works with cmusieve and Dovecot 1.1.16. I assume some problems with the namespace separator. Anyone got any ideas or got sieve running with namespace separator "/" and prefix "INBOX"? Regards, Sebastian

[Dovecot] readdir and rename don't mix; patch included
by Mike Abbott 08 Jul '09

08 Jul '09

Enclosed please find a patch to dovecot-1.1.16 that fixes a common problem we see under load on Mac OS X and HFS+. The symptom is that sometimes readdir() returns EINVAL. The problem is that readdir() and rename() don't mix well, and maildir_scan_dir() renames messages from new/ to cur/. The solution I chose is just to retry scanning the directory, since code to rescan is already present. An alternative solution would be to read the entire directory first, then process the contents; that is, to do all the readdirs before any renames. The patch is like Apple's previous ones, all tagged with /*APPLE*/ and formatted to simplify our merges. Please reformat it as you desire. It should also apply easily to 1.2.0. --- dovecot-1.1.16/src/lib-storage/index/maildir/maildir-sync.c 2009-05-20 16:42:49.000000000 -0500 +++ dovecot/src/lib-storage/index/maildir/maildir-sync.c 2009-07-07 19:50:37.000000000 -0500 @@ -354,7 +354,8 @@ return -1; } -static int maildir_scan_dir(struct maildir_sync_context *ctx, bool new_dir) +static int maildir_scan_dir(struct maildir_sync_context *ctx, bool new_dir, + bool final) /* APPLE */ { struct mail_storage *storage = &ctx->mbox->storage->storage; const char *path; @@ -486,6 +487,11 @@ } } + /* APPLE - rename can cause readdir to fail with EINVAL; force + quiet rescan unless this is the final such rescan already */ + if (errno == EINVAL && move_count && !final) + move_count = MAILDIR_RENAME_RESCAN_COUNT + 1; + else /* APPLE reduce code deltas */ if (errno != 0) { mail_storage_set_critical(storage, "readdir(%s) failed: %m", path); @@ -772,7 +778,8 @@ that new/ dir is checked as well. it's a good idea anyway. */ unsigned int count = 0; - while ((ret = maildir_scan_dir(ctx, TRUE)) > 0) { + while ((ret = maildir_scan_dir(ctx, TRUE, + count == MAILDIR_SCAN_DIR_MAX_COUNT)) > 0) { /* APPLE */ /* rename()d at least some files, which might have caused some other files to be missed. check again (see MAILDIR_RENAME_RESCAN_COUNT). */ @@ -783,7 +790,8 @@ return -1; if (cur_changed) { - if (maildir_scan_dir(ctx, FALSE) < 0) + if (maildir_scan_dir(ctx, FALSE, + FALSE) < 0) /* APPLE */ return -1; }

Attached is a patch which in my environment (Linux/Heimdal 1.2.1) fixes cross-realm GSSAPI authentication. Changes it makes: 1. When using krb5_kuserok, do not call gss_compare_name to check that authn_name and authz_name are the same. Instead, make TWO calls to krb5_kuserok, one for each ID. If both IDs are acceptable, allow the login. 2. Disable checking that the name is a GSS_KRB5_PRINCIPAL_NAME, as this doesn't appear to be always the case for the authz_name. If I create a .k5login listing both username@REALM1 and username@REALM2, and make that file follow the appropriate security restrictions (world read, user only write permissions), this lets me use GSSAPI logins with principals from either REALM1 or REALM2. This leaves untouched the behavior in the case where krb5_kuserok is not available. Bryan Jacobs

[Dovecot] v1.2.0 released
by Timo Sirainen 08 Jul '09

08 Jul '09

http://dovecot.org/releases/1.2/dovecot-1.2.0.tar.gz http://dovecot.org/releases/1.2/dovecot-1.2.0.tar.gz.sig As promised. No changes since v1.2.rc8 (except packaged in OS X, since CentOS 5 autotools didn't add support for configure --docdir). Below are the largest changes since v1.1: * When creating files or directories to mailboxes, Dovecot now uses the mailbox directory's permissions and GID for them. Previous versions simply used 0600 mode always. For backwards compatibility dovecot-shared file's permissions still override these with Maildir. * SQL dictionary (quota) configuration file is different than in v1.1. See doc/dovecot-dict-sql-example.conf for the new format. * deliver -m: Mailbox name is now assumed to be in UTF-8 format, not modified-UTF7. Stephan Bosch's new Sieve implementation also assumes UTF-8 format in fileinto parameters. + Full support for shared mailboxes and IMAP ACL extension. The code is mainly from Sascha Wilde and Bernhard Herzog. + IMAP: Added support for extensions: CONDSTORE, QRESYNC, ESEARCH, ESORT, SEARCHRES, WITHIN, ID and CONTEXT=SEARCH. + SEARCH supports INTHREAD search key, but the rest of the INTHREAD draft isn't implemented yet so it's not advertised in capability. + THREAD REFS algorithm where threads are sorted by their latest message instead of the thread root message. There is also no base subject merging. + IMAP: Implemented imap-response-codes draft. + Thread indexes for optimizing IMAP THREAD command and INTHREAD search key. + Added userdb checkpassword (by Sascha Wilde) + Virtual mailboxes: http://wiki.dovecot.org/Plugins/Virtual + Autocreate plugin: http://wiki.dovecot.org/Plugins/Autocreate + Listescape plugin: http://wiki.dovecot.org/Plugins/Listescape

[Dovecot] rquota RPC with netapp filer
by Ralf Becker 07 Jul '09

07 Jul '09

Hello list, with dovecot 1.2 on AIX rquota RPC calls fail with quota-fs: remote ext rquota call failed: RPC: 1832-012 Program/version mismatch when using a netapp filer. This is what netapp says: Bug ID 97288 Title Support requested for rquota version 2 Bug Severity 5 - Suggestion Bug Status Closed Product Data ONTAP Bug Type NFS Description Linux has implemented its own extensions to the rquota protocol as a version 2 of that protocol. ONTAP only supports v1 as that is the only version defined by Sun, the owner of that RPC program number. Workaround - Fixed-In This bug is not scheduled to be fixed, you may opt to Version open a technical support case if you would like to contact Network Appliance regarding the status of this bug. A complete list of releases where this bug is fixed is available here. So this should be no AIX specific problem. Using the attached rquota.x fixes the problem. In addition you have to disable group quota checking by adding "user" to your "quota" definition. Otherwise you'll see: quota-fs: rquota not compiled with group support Regards, Ralf -- ______________________________________________________________________ Dipl.-Inform.

[Dovecot] AUTH PLAIN error with Thunderbird and Dovecot 1.2

Hi, a few days ago I started to get some complaints about authentication delays from Thunderbird POP3 users. After some debugging it turned out that the problem was introduced somewhere between 1.2rc3 and 1.2rc7 (1.2.0 is still affected). A session with Thunderbird 2.0.0.22 against 1.2rc3 looks like this: <<< +OK Dovecot ready. >>> CAPA <<< +OK <<< CAPA <<< TOP <<< UIDL <<< RESP-CODES <<< PIPELINING <<< STLS <<< USER <<< SASL PLAIN LOGIN <<< . >>> AUTH PLAIN <<< + >>> <base64> <<< +OK Logged in. and with 1.2.0 (same client, same config, just replaced the server binaries) <<< +OK Dovecot ready. >>> CAPA <<< +OK <<< CAPA <<< TOP <<< UIDL <<< RESP-CODES <<< PIPELINING <<< STLS <<< USER <<< SASL PLAIN LOGIN <<< . >>> AUTH PLAIN [ 2 seconds delay ] <<< -ERR Authentication failed. >>> AUTH LOGIN [ 5 seconds delay ] <<< + <base64> >>> <base64> <<< + <base64> >>> <base64> <<< +OK Logged in.

[Dovecot] troubles with broken clients (iPhone) - again
by Federico Bianchi 07 Jul '09

07 Jul '09

The PC (Outlook) is accessing the mailbox via POP3, the iPhone is using IMAP; please consider we are talking about a user's home setup, so it's pretty difficult to have a more detailed report on his part (Outlook version, iPhone OS version, xDSL router type and configuration, etc.). The mail server 'dovecot -n' output is attached. The symptoms: when the Mail application is "closed" on the iPhone, Outlook still says the mailbox is in use; a Dovecot imap process is still active for that user even after a few minutes (manually killing it releases the lock, thereby leaving the inbox available for Outlook). >From the client side, there is a seemingly relevant article at http://blogs.sun.com/chienr/entry/iphone_supports_imap_idle it describes, among others, the "Settings / Mail / Auto-Check" and "Settings / General / Auto-Lock" parameters; from my point of view, however, being able to solve the problem directly on the server would be far better, and might also accomodate other broken clients we haven't seen yet: that's why I asked you whether there is a way to tell Dovecot only one POP3 or IMAP process from the same user, the latest one, can be active at the same time, closing and disconnecting all the others.

I'm sure that isn't an authentication problem. I've tried some days to understand and to find over internet and here in the dovecot mailing list but I've not find a solution yet. I think it's a dovecot internal bug. Someone know what I'm talking about?" Set permissions on the mail folder to 2775 because dovecot runs as its own user and group and you need the mail file in that folder to accept writes from mail and from dovecot groups. Also in the config file dovecot.conf you need to specify if the files are maildir or mbox. They are probably mbox but try both for the error messages.

[Dovecot] Released Sieve v0.1.7 and ManageSieve v0.11.6 for Dovecot v1.2.0
by Stephan Bosch 07 Jul '09

07 Jul '09

Hello Dovecot users, I hereby release new versions of the Sieve packages for the recently released Dovecot v1.2.0 (Congrats Timo!). Apart from small changes to make things compile with Dovecot again, a few other bugs were fixed as well. Unfortunately, the (FreeBSD-specific) 8kb script truncation bug remains. Although it is reported for Dovecot v1.1.16, I see no reason why it should not surface in v1.2.0 as well. Any help is appreciated. Changelog Sieve v0.1.7: + Improved consistency of sieve tool documentation and fixed missing parameters in internal tool help output. + Enhanced extensions configuration, allowing to specify the enabled extensions relatively to the default (patch by Steffen Kaiser). - Forgot to initialize script execution status in Sieve plugin, causing segfaults on compile errors in specific conditions. - Fixed logging in Sieve plugin for execution of default main script (went to STDERR). Changelog ManageSieve v0.11.6: * Adjusted to changes in Dovecot regarding client idle timeout vs authentication timeout. This release now depends on Dovecot v1.2.rc6 or newer. - Fixed CRLF line breaks in compile errors (bug reported by Pascal Volk). - Corrected directory/file creation behavior with respect to mode bits and gid (bug reported by Pascal Volk). - Improved handling of script truncation bugs: connection is now closed and and error is logged (bug itself not fixed yet). - Prevented temp script name from showing up in error output. -- The releases are available as follows: Sieve: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.7.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.7.tar.gz.sig ManageSieve (package + patch): http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.6.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.6.tar.gz.s… http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.0-managesieve-0.11.6.diff.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.0-managesieve-0.11.6.diff.g… -- Have fun testing the new releases and don't hesitate to notify me when there are problems.

[Dovecot] Dovecot-sieve version compatability
by Phill Edwards 07 Jul '09

I'm thinking of upgrading my dovecot version to 1.2 so that I can use the Dovecot sieve plugin instead of the CMU Sieve plugin. My RPM repo for dovecot is ATrpms so I could get dovecot-1.2.0-0_95.el5.i386.rpm from the bleeding ATrpms repo. Would this be compatible with dovecot-sieve-1.1.6-9.el5.i386.rpm which is in the stable repo, or would I need to find a later dovecot-sieve version somewhere? Regards, Phill

Hello, can`t sort Mails with sieve in Subfolders. Mails only delivered in my INBOX.

Hi All, I've got a brand new dovecot installation. I'm new to dovecot, so please be gentle :-) Anyway, I'm getting some errors when I try to connect to dovecot. I've tried searching the web and haven't been able to find a lot of information.

[Dovecot] mbox sync failure2
by Alnis Morics 06 Jul '09

06 Jul '09

Hello, list, I'm new here and also new to Dovecot. On Friday evening (perhaps not the best moment...) I sent the following question but it seems to have been lost somehow: Yesterday I had to reboot my server machine and I think there was an email client connected from the LAN during the reboot which I did not notice then. Now that mailbox is no longer accessible: as soon as I try to connect, it lets me wait forever while openin the folder, and cycles endlessly this message in the logs: Jul 2 19:40:37 myhostname dovecot: imap-login: Login: user=<username>, method=PLAIN, rip=#.#.#.#, lip=#.#.#.#, TLS Jul 2 19:40:37 myhostname dovecot: IMAP(username): unlink(/var/mail/username.lock) failed: Permission denied Jul 2 19:40:48 myhostname dovecot: IMAP(username): file mbox-sync.c: line 1372 (mbox_sync_handle_eof_updates): assertion failed: (trailer_size <= 2) Jul 2 19:40:48 myhostname dovecot: IMAP(username): Raw backtrace: imap [0x80b2081] -> imap [0x80b1f99] -> imap [0x807a536] -> imap [0x807ae71] -> imap(mbox_sync+0x422) [0x807d3c2] -> imap(mbox_storage_sync_init+0x3e) [0x807d8de] -> imap(imap_sync_nonselected+0x1c) [0x806446c] -> imap(_cmd_select_full+0xc3) [0x805be83] -> imap(cmd_select+0x19) [0x805c059] -> imap [0x805d5ef] -> imap [0x805d690] -> imap(_client_input +0x74) [0x805dd64] -> imap(io_loop_handler_run+0xf0) [0x80b7e20] -> imap(io_loop_run+0x18) [0x80b7338] -> imap(main+0x478) [0x8066388] -> /lib/i686/cmov/libc.so.6(__libc_start_main+0xe5) [0xb7e36455] -> imap [0x8058561] Jul 2 19:40:48 myhostname dovecot: child 2459 (imap) killed with signal 6 (I have Debian Lenny with dovecot 1.0.15.; protocol: imaps; mailbox: mbox; lock: dotlock) I tried to add the user dovecot to the group mail and give the group mail write permission to the mailbox. The permission errors stopped appearing but everything else is still there, including .lock file and 3 imap-login processes that resume as soon as I try to kill them. There are also 2 unimportant mailboxes that still work. I can view the beginning of the "username" mailbox with mc inner viewer, but it hangs as I go to the end of file. Tried to copy the file so I could freely experiment with it but the copying hung up when it reached 87 % (the file is 1.1 GB). The copied part was unreadable. Tried to formail -ds < /var/mail/username >> /backup/usernameJul3 but with the same result. Is there a way to repair the synchronization of the mbox? Or at least a way to recover its content? ------------------------------------------------------- After that I also tried to "shutdown -F -r now" but to no effect. (filesystem is ext3) Now I'm really in trouble. Could someone, please, suggest what I could try to do to solve this? Thanks.

[Dovecot] 1.1.16 and global ACLs
by Axel Luttgens 04 Jul '09

04 Jul '09

I was going to test 1.1.16 so as to see how it handles global ACLs (in the hope to have a possible comparison with 1.2.0's odd behavior), when I encountered the problem described hereafter. Note that just disabling ACLs is sufficient to get back a fully functional imap binary. So, should there be some plans for a 1.1.17 version, perhaps could the info provided here prove somewhat useful. Folowing telnet session: # telnet 127.0.0.1 imap Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. * OK Dovecot ready. a1 login testuser ****** a1 OK Logged in.

[Dovecot] Urgent problem with deleting emails and maildirsize
by Jose Luis Marin Perez 04 Jul '09

04 Jul '09

Dears Sirs, I hope they can help me with this problem since it is urgent. I've completed the migration from Courier to Dovecot that has been running correctly, the only problem is that maildirsize file is not updated when you delete the emails, resulting in accounts that reach to 100% faster, so I have to manually delete this file. Through Dovecot can be configured to automatically update when maildirsize delete emails?

[Dovecot] How to rebuild index?
by Max Ivanov 03 Jul '09

03 Jul '09

I've deleted some mails using my handmade tool, it deletes some files in "cur" subdir, but deleted messages are still appear in thunderbird. I believe that's because of stale index file. Is it safe to delete dovect.index? Or what else should I delete/modify to make TB view in sync with real state of filesystem?

Now that mailbox is no longer accessible: as soon as I try to connect, it lets me wait forever while openin the folder, and cycles endlessly this message in the logs: Jul 2 19:40:37 myhostname dovecot: imap-login: Login: user=<username>, method=PLAIN, rip=#.#.#.#, lip=#.#.#.#, TLS Jul 2 19:40:37 myhostname dovecot: IMAP(username): unlink(/var/mail/username.lock) failed: Permission denied Jul 2 19:40:48 myhostname dovecot: IMAP(username): file mbox-sync.c: line 1372 (mbox_sync_handle_eof_updates): assertion failed: (trailer_size <= 2) Jul 2 19:40:48 myhostname dovecot: IMAP(username): Raw backtrace: imap [0x80b2081] -> imap [0x80b1f99] -> imap [0x807a536] -> imap [0x807ae71] -> imap(mbox_sync+0x422) [0x807d3c2] -> imap(mbox_storage_sync_init+0x3e) [0x807d8de] -> imap(imap_sync_nonselected+0x1c) [0x806446c] -> imap(_cmd_select_full+0xc3) [0x805be83] -> imap(cmd_select+0x19) [0x805c059] -> imap [0x805d5ef] -> imap [0x805d690] -> imap(_client_input +0x74) [0x805dd64] -> imap(io_loop_handler_run+0xf0) [0x80b7e20] -> imap(io_loop_run+0x18) [0x80b7338] -> imap(main+0x478) [0x8066388] -> /lib/i686/cmov/libc.so.6(__libc_start_main+0xe5) [0xb7e36455] -> imap [0x8058561] Jul 2 19:40:48 myhostname dovecot: child 2459 (imap) killed with signal 6 (I have Debian Lenny with dovecot 1.0.15.) I tried to add the user dovecot to the group mail and give the group mail write permission to the mailbox. The permission errors stopped appearing but everything else is still there, including .lock file and 3 imap-login processes that resume as soon as I try to kill them. There are also 2 unimportant mailboxes that still work. I can view the beginning of the "username" mailbox with mc inner viewer, but it hangs as I go to the end of file. Tried to copy the file so I could freely experiment with it but the copying hung up when it reached 87 % (the file is 1.1 GB). The copied part was unreadable. Tried to formail -ds < /var/mail/username >> /backup/usernameJul3 but with the same result. Is there a way to repair the synchronization of the mbox? Or at least a way to recover its content?

[Dovecot] Dovecot Support Added to OSSEC
by Michael Starks 03 Jul '09

03 Jul '09

I have added (beta) Dovecot support for the OSSEC HIDs. It will detect certain attacks and error conditions, and optionally block the attacker (similar to fail2ban). Rather than re-hash the details here, I refer you to the OSSEC mailing list for details on how to install. I would appreciate any feedback either here, there, or privately. The idea is to get a few people trying it so I thought a post here would be good, too.

[Dovecot] about Update Road and no IDLE in CAPABILITY
by kfx 02 Jul '09

02 Jul '09

Hi list, I'm in the path of moving from courier-imap to dovecot and testing it since 1.2-rc3. So far it is very promising. Thank you for your amazing work. So my first question is: what is the recommended update road ? For now, I first "managesieve patch"/compile the source, go on to the old source folder and do a "make uninstall", switch back to the new source folder and do the "make install". As I am using dovecot-sieve and managesieve, the update is a little bit tricky. My second question is how to have the IDLE mode to appear in the server's CAPABILITY announce (without touching imap_capability in the conf ?) I think the IDLE mode is working because when I send me a mail from the server directly in command line like: " echo test | mail -s test my(a)address.com" The mail immediately pop-up in my thunderbird from my workstation. # !tel telnet 127.0.0.1 143 Trying 127.0.0.1... Connected to 127.0.0.1. Escape character is '^]'. * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE STARTTLS AUTH=PLAIN] My Message ------- No IDLE.

[Dovecot] Directory Layout Performance
by Mario Antonio Garcia 02 Jul '09

02 Jul '09

From a performance perspective: Which Directory layout is better: 1. All mailboxes are stored in a single directory and prefixed with a dot or 2. Maildirs using physical directories, such as: Maildir/folder/subfolder/ It looks like the second option -- File Sytem Layout (LAYOUT=fs) -- could spread the load in a better way ...... I do not expect a user reaching maximum number of subfolders in linux , but what about those heavy users with a lot of sub-folders: Is there a significant performance gain by choosing a specific Directory Layout ... Any Comments? Regards, Mario Antonio

[Dovecot] keeping 2 dovcots in sync?
by joakim＠verona.se 02 Jul '09

02 Jul '09

I would like to have one master dovecot instance that gets email, and a slave dovecot on my laptop. I use maildir, and I was thinking of doing this with unison, but I suppose dovecots indexes would go out of sync whenever I used unison. There seems to be a number of imap folder synchronizers, but I have heard they are troublesome. Any hints? -- Joakim Verona

[Dovecot] dovecot lda and postfix
by Mauricio Tavares 02 Jul '09

02 Jul '09

I do not know if this is a help request to solve a problem but to understand what is going on. I am going to start with the problem description as I see it and we will go from there. I have postfix setup to use dovecot for tls/sasl in addition to its normal imap/pop3 functions. Postfix is also setup to do virtual domains, getting its information from the files valias, vmaps, and vhosts which are all located in its /etc/postfix directory: # Virtual domain stuff virtual_mailbox_domains = /etc/postfix/vhosts.txt virtual_mailbox_base = /var/spool/vmail virtual_mailbox_maps = hash:/etc/postfix/vmaps.txt # 1500:1500 is user virtual virtual_uid_maps = static:1500 virtual_gid_maps = static:1500 virtual_alias_maps = hash:/etc/postfix/valias.txt Dovecot uses its own unix passwd-like files to do authentication. In fact, as you can see, I broke them apart so I can make the actual password file readable only by root: mail_location = maildir:~/ auth default { passdb passwd-file { args = /etc/dovecot/passwd } userdb passwd-file { args = /etc/dovecot/users } } I know the norm is to use a database or at least ldap, but I had my reasons. Mailscanner is also installed. So, the whay things have been working so far was, postfix receives an email and checks if it is recipient exists here. If so, it would pass it to mailscanner and then get it back, when it would then drop it at the recipient's mailbox in /var/spool/vmail/domain.com/user. A user would then connect to dovecot to retrieve the email. And when an email was to be sent, postfix would use dovecot to do the user authentication. So far so good. Now I want to add dovecot lda so I can run the cmu sieve plugin (this is dovecot 1.0.1) primarily to move emails mailscanner (and spamassassin) thinks that are spam to each virtual user's Spam maildir directory. So, reading http://wiki.dovecot.org/LDA/Sieve/CMU, I add the following entries to dovecot.conf: protocol lda { mail_plugin_dir = /usr/lib/dovecot/modules/lda sendmail_path = /usr/lib/sendmail auth_socket_path = /var/run/dovecot/auth-master mail_plugins = cmusieve global_script_path = /etc/dovecot/scripts/dovecot.sieve mail_debug = yes log_path = /var/log/dovecot-lda info_log_path = /var/log/dovecot-lda } # I am being rather lazy in my sieve config entry. I did make sure the file # is owned by virtual:virtual plugin { sieve = /etc/dovecot/scripts/dovecot.sieve } socket listen { master { path = /var/run/dovecot/auth-master mode = 0600 user = virtual # User running Dovecot LDA's deliver } # Postfix is using dovecot for SMTP AUTH (SASL) client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } Then, based on http://wiki.dovecot.org/LDA/Postfix, I edit postfix's master.cf: dovecot unix - n n - - pipe flags=DRhu user=virtual:virtual argv=/usr/lib/dovecot/deliver -f ${sender} -d ${user}@${nexthop} and main.cf: dovecot_destination_recipient_limit = 1 virtual_transport = dovecot # mailbox_virtual_domains was already defined as shown above The dovecot.sieve file looks like this: require ["fileinto", "reject"]; # Spam stuff if header :contains "X-Spam-Level" "********************" { discard; stop; } elsif header :contains "X-Spam-Status" "Yes" { fileinto "Spam"; stop; } So, I restart it and try to send a message to my account, say raub(a)domain.com, in this machine. It bounces back saying the user does not exist. I check th elog files and they seem to agree: dovecot: 2009-06-30 16:31:44 Info: auth(default): passwd-file(raub(a)domain.com): lookup: user=raub(a)domain.com file=/etc/dovecot/users dovecot: 2009-06-30 16:31:44 Info: auth(default): passwd-file(raub(a)domain.com): unknown user Now this is where I am trying to understand what is going on. It seems to me that postfix *or* dovecot went to /etc/dovecot/users looking for raub(a)domain.com. Not finding it there (I had it defined there as raub simply; I have mail_location = maildir:~/ in dovecot.conf, so the username in this file does not need to be related to the user's email address), it decided user does not exist and bounced back. My testing indicated that happened after postfix passed the email to dovecot lda (I guess that virtual_transport = dovecot means it goes to master.cf and looks for the dovecot entry and then passes the message to it). That would mean postfix is not using vmaps to see if the user exists anymore. Instead, it is delegating checking if a user exists to dovecot, which is not what I want to do. I want postfix to worry about getting mail and making sure the recipient exists. Out of the blue, if I replaced the virtual_mailbox entry with local_transport = dovecot, or nothing at all, mail is delivered as it should. My gut feeling is the master.cf dovecot entry is responsible for the problem, but I am not sure because I really do not know everything that is going on there; this is the first time I venture in that file. So, could anyone shed some light on what is causing the problem? Thanks!

[Dovecot] Dovecot / Sieve

Hi, As the "new Sieve implementation" is using a "gratefully stolen copy of deliver.c from dovecot" (i.e. a dirty code in mail-raw.c), would it be possible for the Sieve piece 1 - to be using files from dovecot directly rather than copying&changing it (which is very bad for maintenance) 2 - to be incorporated in the hg/mercurial tree of dovecot ? Thanks a lot in advance, Joan

[Dovecot] short-cut for install prefix in conf file?
by Steffen Kaiser 01 Jul '09

01 Jul '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, is there a way to shortcut the absolute path in the dovecot.conf file for the various referenced files? Something like: Now: acl = pgsql:/usr/local/dovecot-1.2.rc8acl-hook2/etc/dovecot-dict-acl-sql.conf mail_executable = \ /usr/local/dovecot-1.2.rc8acl-hook2/libexec/dovecot/rawlog \ /usr/local/dovecot-1.2.rc8acl-hook2/libexec/dovecot/imap Short #1 - relative to dir of conf file acl = pgsql:dovecot-dict-acl-sql.conf mail_executable = ../libexec/dovecot/rawlog ../libexec/dovecot/imap Relative paths are currently evaluated relative to /tmp or '.', it looks like. Because of the different useages of the .conf file, this variant will be troublesome, I guess. Short #2 - use variables as in the shell INSTALL := /usr/local/dovecot-1.2.rc8acl-hook2 acl = pgsql:$INSTALL/etc/dovecot-dict-acl-sql.conf mail_executable = \ $INSTALL/libexec/dovecot/rawlog \ $INSTALL/libexec/dovecot/imap So you need to define the path just one time in the file. Maybe use %$INSTALL instead of $INSTALL, in order to _not_ introduce another metacharacter and break backwards compatibly. Short #3 - pseudo variable (%* here) with modifier (I == installpath) acl = pgsql:%I*/etc/dovecot-dict-acl-sql.conf The background is to support multiple parallel installations, e.g. during testing, I cannot rely on symlinks, but want that all stuff in a conf file is referenced to the same install tree.

Re: [Dovecot] No folders listed in felamimail

dovecot-request(a)dovecot.org wrote: > I thought I try and solve a long standing bug we've had with felamimail > not listing folders from our dovecot server. > Is it bad form to reply to your own postings? I've managed to find the source of the problem and apply a temporary hack to get the folders listed. I'm not sure whether it's a bug or a feature or if there is a proper fix. The issue is that our mail folder layout is still based on "elm" (hands up everyone who remembers that) and we store all the users folders in mbox format under a directory called Mail in their home directory. We've defined a namespace in dovecot called "" which knows to look there and will list all the folders. However, we have run uw-imap in the past so we have a hidden namespace that maps all the folders starting "Mail/" to the new namespace so that we didn't have to change any of the clients. Egroupware has a bunch of code that tries to guess what sort of IMAP server is on the other end based on what folders it can find. One of those checks is for "Mail" and when it finds it it assumes that's the place to go looking for folders rather than using what the Namespace command returned. I'm guessing that this was put in by someone with the same layout as we used to have with "elm" trying to overcome the lack of a configuration file in uw-imap. Our "Mail/" namespace doesn't list any folders and so felamimail can't see anything for the user. My temporary hack was to comment out all the IMAP server guessing code and that fixes the problem for us. Now I need to find out how felamimail deals with IMAP servers that can't have mail folders containing messages and subfolders (it's one or the other with dovecot using mbox) Jon.

[Dovecot] configure dovecot to invoke pam_setcred() from the same process that accesses ~/Maildir?
by Adam Megacz 30 Jun '09

30 Jun '09

Hello. I'm wondering how one would go about configuring dovecot to invoke pam_setcred() from the same process as (or a parent process of) the process which eventually reads the user's mail off the disk. This is required for pam modules that set kernel-level credentials which are later used to access the user's mail files. In particular, I'm trying to use dovecot with pam_krb5 (which associates a ticket cache to a specific pid) and pam_afs_session (which associates tokens to a specific process authentication group -- roughly equivalent to a process and all its descendents). Thanks, - a

[Dovecot] ACLs, imap and launchd
by Axel Luttgens 30 Jun '09

30 Jun '09

I was going to experiment with ACLs when I faced a small problem. It is just sufficient to enable the acl plugin for getting the behavior described hereafter. When launching dovecot from the command line, one gets: sh-3.2# /usr/local/dovecot/sbin/dovecot -F ILoading modules from directory: /usr/local/dovecot-1.2.rc6/lib/ dovecot/imap IModule loaded: /usr/local/dovecot-1.2.rc6/lib/dovecot/imap/ lib01_acl_plugin.so IEffective uid=65534, gid=65534, home=/tmp Iacl: No acl setting - ACLs are disabled ^C In fact, a "dummy" imap process is run so as to fetch the capability (see master-settings.c); that process is run with an hardcoded uid/gid 65534.

[Dovecot] No folders listed in felamimail
by Jonathan Knight 30 Jun '09

30 Jun '09

Egroupware 1.4.004 I thought I try and solve a long standing bug we've had with felamimail not listing folders from our dovecot server. Watching dovecot's packet dumps I'm seeing dovecot do a namespace call and the a list call. Felamimail does a namespace and gets back * NAMESPACE (("" "/")) NIL NIL which is how I've configured dovecot to keep the client configuration very simple. Now Felamimail does a LIST "" "" which gets no folders returned and is obviously why it won't show anything in the felamimail display. I was expecting felamimail to do something more like: LIST "" "%" or LIST "" "*" Is there something I need to configure to make felamimail happy with our dovecot configuration? We use dovecot with outlook express, thunderbird (1,2,3), Mozilla, squirrelmail, iPod, iPhone and symbian with no issues so I'm tending towards felamimail being the source of the problem. Jon.

Hi, I'm a bit confused by the Wiki. Do the settings "sieve_dir" and "sieve_global_dir" belong to the lda or the plugin section (Dovecot 1.1.11)? Thanks Rainer

[Dovecot] SSL / TLS
by Carlos Williams 30 Jun '09

30 Jun '09

I am running Postfix and Dovecot on my mail server. I am required now to have SSL/TLS on my mail server. I did check and found out that I have a SSL certificate with Verisign issued to my mail servers FQDN. Now my question is when reading the Dovecot Wiki, I noticed it said that it is not common to use SSL but rather TLS on most mail servers. Even though SSL will work, which should I use on my server? We already have a purchased SSL certificate but does that really matter? Should I simply just revoke that certificate & use TLS instead? So when I read this link: http://wiki.dovecot.org/SSL/DovecotConfiguration Is it talking about a actual SSL certificate or TLS? Thanks for any clarification! - Carlos

[Dovecot] Users with large (4GB) inboxes crippling dovecot
by robforrest 29 Jun '09

29 Jun '09

Hi all, I'm new here and would very much appreciate any help you can give me. We are running a rather outdated mail server that until recently has been running beautifully. Under the pretense of "it is ain't broke, don't fix it" it hasn't been updated so is running Fedora Core 4 and dovecot v0.99.14. What is happening is that as users log in (via thunderbird), they are shown the contents of their mailboxes. However, when they try and access a given email, they get no response even if they wait upwards of 10 minutes. I believe that the problem has arisen from their huge inboxes, several users have inboxes in excess of 4GB. Do any of you know how I could split these large mbox files down in to manageable chunks of 1GB? Please be aware that I only have remote access to the server over a modest internet connection. Thanks again for any suggestions.

[Dovecot] Recommended Groupware?
by it-dovecot＠ml.epigenomics.com 29 Jun '09

29 Jun '09

Hi, is there a recommended groupware (email + calendar + address book + syncing with mobile devices) on top of an existing dovecot installation? Most existing commercially supported groupwares come with their own mail storage engine. I would like to keep dovecot as the email storage engine because of the maildir format which greatly helps with backup & restore. Regards -- Robert Sander

[Dovecot] Dovecot Expire doesn't work
by Stef Simoens 29 Jun '09

29 Jun '09

Hello, I'm using dovecot and I want to use the "expire" plugin. However, it doesn't work, i.e. mails do not get deleted. I ran `/usr/sbin/dovecot --exec-mail ext /usr/libexec/dovecot/expire-tool --test` and besides printing Info: stef/Trash: no messages left Info: stef/Spam: no messages left it doesn't do anything (especially not deleting e-mails). Obviously, in stef/Trash and stef/Spam, there are e-mails waiting to be deleted. I'm using dbox as mail storage; and use dbox:/var/mail/%u as mail_location in dovecot.conf. Furthermore, I'm running 1.1.16 on a gentoo PPC system. This is the output from `dovecot -n` # 1.1.16: /etc/dovecot/dovecot.conf # OS: Linux 2.6.29-gentoo-r2 ppc Gentoo Base System release 1.12.11.1 xfs listen: *, [::] ssl_cert_file: /etc/ssl/dovecot/server.pem ssl_key_file: /etc/ssl/dovecot/server.key login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login verbose_proctitle: yes mail_privileged_group: mail mail_location: dbox:/var/mail/%u mail_plugins: expire auth default: verbose: yes debug: yes passdb: driver: pam args: * userdb: driver: passwd socket: type: listen master: path: /var/run/dovecot/auth-master mode: 384 plugin: quota: fs:Disk Quota expire: Trash 7 Spam 30 expire_dict: proxy::expire dict: expire: db:/var/lib/dovecot/expire.db A strace on `/usr/sbin/dovecot --exec-mail ext /usr/libexec/dovecot/expire-tool --test` shows the following output: mkdir("/var/mail/root", 0770) = -1 EEXIST (File exists) stat64("/var/mail/root/Trash/dbox-Mails", 0xbfda2708) = -1 ENOENT (No such file or directory) write(2, "Info: stef/Trash: no messages lef"..., 35Info: stef/Trash: no messages left ) = 35 which explains why nothing happens (stat64("/var/mail/root/Trash/dbox-Mails", which is empty, it should not even exist, but it passes by a mkdir), but why does it want to check /var/mail/root and not /var/mail/%u (i.e. why no stat64(/var/mail/stef/Trash/dbox-Mails))? Thanks for your help and kind regards, -- Stef Simoens

[Dovecot] automated email setup and white/blacklists

We are running a Red Hat Enterprise Linux environment with Dovecot IIMAP, Exim and mySQL 5.0.81, Apache 2.2.11 We are looking for several server side scripts: 1. Create a user account automatically at the completion of our registration process. i.e. username(a)ourdomain.com and existing MD5 password that is associated with his/her user account 2. Add a new user to an existing subscriber email whitelist (add buddy function) 3. Add an existing user to an existing subscriber email blacklist (block buddy function) Our preference is to receive access to a publicly available scripts. Alternatively, to come to a commercial arrangement with a party who has written or who is prepared to write the same.

So with only 3 POP3 users, why should so many login processes be spawned? I can understand 10-15. But 100 definitely indicates either the processes are not dying or something else happening on the system which is causing such high number of login processes. The system definitely needs to be checked for some kind of attack, a rogue process running on the system or something else. > >> My idle box has 64 imap-login processes and no, I'm not under a >> dictionary attack :) I am not sure what your load is (user base, system config etc), but I will give you my typical load here. I run mail server for about 6000 users with a mix of 70% POP3 and 30% IMAP (thro webmail). And here are the typical stats (I run a script in the background collecting this data every 5 secs): pop3-logins:12 pop3-connections:8 IMAP-logins:7 IMAP-connections:11 I have read other opinions in this thread by Timo & others. And I am interested in a few things. So if you will indulge me, maybe it will be useful for others who face these kind of issues Timo Wrote: You can also just decrease login_process_max_count Wouldn't decreasing the login_process_max_count simply create more problems. Now users will start experiencing timeouts sooner than before, because whatever is causing the login processes to increase (attack, rogue process or whatever) will *always* be trying to login and genuine users will be denied login. So without knowing the root cause of the issue simply decreasing or increasing the login_process_max_count will lead to other problems. Correct me if I am wrong. Rodman Wrote: I'll go ahead and lower that limit to something that fits my usage better. No, I think leave that value to default and try and identify the root cause and prevent it. Noel Wrote: What would be nice is, an anti brute force option Yes, that would be nice. But consider a situation where the system is not under brute force attack, but for some reason the number of login processes keep on increasing by the hour. This would ultimately lead the system to deny connections to the users. Is there a way to track what is happening? strace would be too complicated for us field guys to work with. Any suggestions?

[Dovecot] Dovecot v1.2 ACL inheritance for new subfolders (aka copying ACLs)
by Steffen Kaiser 28 Jun '09

28 Jun '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, http://wiki.dovecot.org/ACL mentions: "Currently there is no ACL inheritance." However this applies to a folder inherit ACLs to existing subfolders; when you share a folder and a non-owner creates a sub-folder within, no ACLs are set, hence, the creator cannot access the new folder. Could the "create mailbox"-process copy the ACLs to the sub-folder? Actually, I would like most, if this is done regardless if owner or non-owner creates subfolders.

[Dovecot] bzip2 compression bug
by fernando＠dfcom.com.br 28 Jun '09

28 Jun '09

Hi, I compressed many files using bzip2, but in some cases it crashes. I believe that it is related to dovecot indexes. How to reproduce: Inside a Maildir folder without any indexes yet, compress a message with bzip2 and tryes to access it. At my server is showed the error: Jun 24 00:18:20 maildev dovecot: IMAP(xxx@xxx): FETCH for mailbox Trash UID 1 failed to read message input: No such file or directory Jun 24 00:18:20 maildev dovecot: IMAP(xxx@xxx): Disconnected: BUG: Unknown internal error bytes=329/1050 When I did the same with gzip compression it works as expected (opening the message and creating dovecot indexes). (version, 1.1.16) Best Regards, Fernando

[Dovecot] strange quota behaviour with dovecot 1.1.7
by listacc＠gmx.de 27 Jun '09

27 Jun '09

Hello! I´m running dovecot 1.1.7 (which is the most recent binary of openSuSE 11.1 repository) with Postfix, MySQL and Postfixadmin. Now I´m trying for some days to get quota working, but I get some strange behaviour and I was not yet able to figure out where the error in my configuration is. Quota information is inserted by postfixadmin into a MySQL database. It seems that dovecot is reading this information correctly - when a mailbox is filled up and gets over-quota, further emails are rejected. But then, if I want to increase the quota for this filled-up mailbox in postfixadmin, postfixadmin correctly changes the quota information in MySQL table. After growing quota, mails to the account are accepted again. But my Thunderbird with Quota plugin continues showing the old quota setting. When more mails are sent to this account, it shows a quota > 100%. If I look into the "mailboxsize" file of this account, it still shows the old quota value before I raised it. If I delete the entry in mailboxsize, dovecot writes the old value in again. Seems that dovecot isn´t looking in the MySQL table (but it did after creating the account). But why are mails accepted again if dovecot is not recognizing the raised quota?? If I try now, as a user, to delete mails from the "overfilled" Inbox, it is denied with a "quota exceeded" message. But I´m able to send further mails to this account. The only way to get the account working properly again is to delete the messages directly on the server´s filesystem. I´m very grateful for every hint! regards, Andreas ------------- dovecot -n: # 1.1.7: /etc/dovecot/dovecot.conf # OS: Linux 2.6.27.23-0.1-default x86_64 openSUSE 11.1 (x86_64) ext3 base_dir: /drbd/mail/var/run/dovecot/ log_path: /var/log/dovecot.err info_log_path: /var/log/dovecot.info protocols: imaps managesieve listen(default): * listen(imap): * listen(managesieve): 192.168.1.8:2000 ssl_listen(default): *:993 ssl_listen(imap): *:993 ssl_listen(managesieve): ssl_cert_file: /etc/ssl/certs/imap.domain.crt ssl_key_file: /etc/ssl/private/imap.domain.key verbose_ssl: yes login_dir: /drbd/mail/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 max_mail_processes: 2000 mail_max_userip_connections(default): 30 mail_max_userip_connections(imap): 30 mail_max_userip_connections(managesieve): 10 first_valid_uid: 5001 last_valid_uid: 5001 mail_location: maildir:/drbd/mail/vmail/%d/%n mail_debug: yes 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 mail_plugins(imap): quota imap_quota mail_plugins(managesieve): mail_plugin_dir(default): /usr/lib64/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib64/dovecot/modules/imap mail_plugin_dir(managesieve): /usr/lib64/dovecot/modules/managesieve managesieve_implementation_string(default): dovecot managesieve_implementation_string(imap): dovecot managesieve_implementation_string(managesieve): Cyrus timsieved v2.2.13 sieve_storage(default): sieve_storage(imap): sieve_storage(managesieve): /drbd/mail/vmail/%d/%n/sieve sieve(default): sieve(imap): sieve(managesieve): /drbd/mail/vmail/%d/%n/dovecot.sieve auth default: mechanisms: plain login cram-md5 user: nobody verbose: yes debug: yes debug_passwords: yes passdb: driver: pam passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: passwd userdb: driver: sql args: /etc/dovecot/dovecot-sql.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 432 user: vmail group: vmail plugin: sieve: /drbd/mail/vmail/%d/%n/dovecot.sieve quota: maildir --- dovecot-sql.conf: (...) password_query = SELECT username AS user, password, '/drbd/mail/vmail/%d/%n' AS userdb_home, 'maildir:/drbd/mail/vmail/%d/%n' AS userdb_mail, 5001 AS userdb_uid, 5001 AS userdb_gid FROM mailbox WHERE username = '%u' AND active = '1' (...) user_query = SELECT '/drbd/mail/vmail/%d/%n' AS home, 'maildir:/drbd/mail/vmail/%d/%n' AS mail, 5001 AS uid, 5001 AS gid, concat('*:storage=', quota, 'B') AS quota_rule FROM mailbox WHERE username = '%u' AND active = '1' --- mysql> select quota from mailbox; +-----------+ | quota | +-----------+ | 512000000 | | 512000000 | | 512000000 | | 512000000 | | 512000000 | | 512000000 | | 512000000 | | 512000000 | | 512000000 | | 30720000 | | 30720000 | +-----------+ 11 rows in set (0.00 sec) -- GRATIS für alle GMX-Mitglieder: Die maxdome Movie-FLAT!

[Dovecot] POP3 flag updates

Why does Dovecot add \Seen flag for mails that have been RETRed? Does anyone really want to use this feature? I can't remember why I implemented it originally, perhaps it was just "because other servers do that too". I'm thinking about at least changing pop3_no_flag_updates=yes to be default. There's also of course pop3_enable_last setting to enable LAST command which was removed from POP3 specs. That requires knowing the last RETRed mail, so I guess I should add a check that it can't be enabled without pop3_no_flag_updates=no.

[Dovecot] Spliting Folders for Efficiency
by Daniel Watts 27 Jun '09

27 Jun '09

Dear Timo, Would there be any sense in giving Dovecot the option to split folders into multiple subfolders when they reached a specified size (probably message count) limit? Dovecot would monitor folders and when they reached, say, 10,000 messages, silently split the folder on the filesystem to ensure that access remains fast. I know that Dovecot scales very well but this would give practically unlimited storage capability and also keep things fast. You could even have it so that the latest 100 messages are kept in their own folder for fast access. .Folder.new .Folder.cur .Folder.tmp could become: .Folder__1.new .Folder__1.cur .Folder__1.tmp and .Folder__2.new .Folder__2.cur .Folder__2.tmp with Dovecot merging them before display as just "Folder" within the mail client. This could be further extended so that Dovecot could be configured to store 'old' message folders in a separate location. We could then have slower+cheaper+larger storage mounted so that 'old mail' does not take up the expensive local SCSI disks on the machine. Mail from 2 years ago is much less likely to be accessed than mail from the last week. This would provide very neat behind-the-scenes archiving functionality. Looking forward to hearing your thoughts. Best, Daniel -- Squirrelmail Stable 1.4.8 (and developing on 1.5.2) PHP 5.x Hardened with Eaccelerator Apache 2.x Mysql 5.0.x Imapproxy over Dovecot 1.0.rc27 with Maildir all running on Gentoo Linux for ~5,000 users.

[Dovecot] Sieve/ManageSieve integration into pkgsrc
by Edgar Fuß 27 Jun '09

27 Jun '09

I'm integrating Sieve (the new one) and ManageSieve into wip/dovecot. Currently, this works as dovecot options because dovecot must be built before sieve can be configured and sieve must be built before managesieve can be configured/built. Now, the question arose what the long-term solution (in pkgsrc) should be. To my understanding, with dovecot 2.0, ManageSieve will no longer need to patch dovecot. But what about both Sieve and ManageSieve depending on doevcot sources in order to build (or on libraries dovecot only builds internally)? The preferred way (for pkgsrc) would be if both Sieve and ManageSieve could be built as stand-alone packages and not needing a dovecot source tree to build. What's the long-term plan for Sieve/ManageSieve in this respect? The pkgsrc infrastructure (intentionally) doesn't like a package depending on anothers package working directory in order to build. So with these cross-dependencies, the only pkgsrc ways to go would be either to build it all as one package with options (that's what I currently do) or extract, patch, configure and build dovecot inside a sieve package.

[Dovecot] dovecot and vmailmgr/qmail mailboxes
by Mij 26 Jun '09

26 Jun '09

Hello folks, Time ago I worked on a patch for dovecot to work with vmailmgr http://mij.oltrelinux.com/net/dovecot-qmail-vmailmgr/ The patch was required because, despite vmailmgr complies with the checkpassword interface supported by dovecot, dovecot snips the mailbox directory returned by the authentication module at colon characters ':'. Incidentally, vmailmgr maps any "name.surname@domain" to "~domain/users/name:surname" (a standard practice in the qmail world, see eg http://www.qmail.org/man/man5/dot-qmail.html at "For security") This path dovecot would then parse as "~domain/users/name". An authentication module can't do anything about it, as this is due to dovecot collecting accounting information in one common buffer, tokenized by ':' separators. I soon stopped updating the patch because I didn't see much point in running indefinitely after releases. However, a bunch of people wrote me over the last years asking for details or updates. Partially for having a similar requirement myself, partially drafted by such feedback, I recently wrote a "compromise" wrapper solution (attached). It does not require patching dovecot (external module) and it's thus (supposedly) durable across dovecot releases; however, it cannot help with the colon problem. The wrapper works as follows: 1) compile and install: # cc -O2 -Wall -o checkvpw-dovecot-wrapper checkvpw-dovecot-wrapper.c # install -s -o root checkvpw-dovecot-wrapper /usr/local/bin 2) edit dovecot.conf, setup the auth section as follows: ============ auth default { mechanism = plain passdb checkpassword { args = /usr/local/bin/checkvpw-dovecot-wrapper } userdb prefetch { } user = root } ============ If "name.surname@domain" wants to be created, the administrator shall instead create the user "namesurname@domain" and an alias "name.surname@domain" pointing to it. This may be conceivable for new installations, but it is not for scenarios where dovecot is to replace another server on top of an existing user base. Of course, it's very desirable to support "." users too. I see that it would require several changes in the code, but I'd like to hear your opinion on this. What about - using a different separator than ":", less common and safer. Could '\0' be one? If not, what about '*'? - as a quicker & dirtier solution, what about allowing escaping? One can modify the auth module to replace ":" with "\:", if dovecot is instructed to avoid tokenizing when a "\" precedes a ":". - as an alternative, dovecot may require the module to chdir() to the mailbox directory instead of returning its path as a string, and subsequently operate locally on mailbox-relative paths. I can't guess how compatible this is with the current design. In the next days, I will publish such wrapper to the webpage. For your convenience, I will invite interested users to show up on this thread; this should help you in assessing how this is interesting for people. bye

That is not right, no matter what. >> No, login_processes_count matters. How? If my understanding is correct, you have extra 3 login processes created to cater to new connections. So with only 3 POP3 users, why should so many login processes be spawned? I can understand 10-15. But 100 definitely indicates either the processes are not dying or something else happening on the system which is causing such high number of login processes. The system definitely needs to be checked for some kind of attack, a rogue process running on the system or something else. Regards --Rao

[Dovecot] dovecot-acl-list not honouring owner / permissions that are set on dovecot-shared
by Stuart Rowan 25 Jun '09

25 Jun '09

Hi, I've just upgraded our dovecot installation from 1.0.15 to 1.1.13. This went smoothly and just worked -- thank you very much for writing such a high performance and robust piece of software. However, we have a shared mailbox that people can subscribe to. After upgrading to 1.1.13 ... dovecot tries to create a dovecot-acl-list file in the top level of this ... but it creates it chown'd to the first logged in user with a umask of -rw- --- --- A. -rw------- 1 userA shared 17179 2009-06-25 11:10 /home/imapshared/SharedMaildir/dovecot-acl-list Everyone else who tried to access the shared folder (and hence dovecot tried to read / update the dovecot-acl-list file) caused an error to be logged to the error.log I changed the permissions (once I realised what had gone wrong) to match those on the dovecot-shared file and all was well as everyone can now read/update it. B. -rw-rw---- 1 imapshared shared 17179 2009-06-25 11:19 /home/imapshared/SharedMaildir/dovecot-acl-list -rw-rw---- 1 imapshared shared 0 2008-04-25 13:20 /home/imapshared/SharedMaildir/dovecot-shared Also from time to time the permissions seem to get changed back on dovecot-acl-list inexplicably to those in situation A -- usually following a restart of dovecot but I haven't been able to reproduce this reliably. This seems like a bug to me ... do you agree / is there a sensible work-around? The declaration in dovecot.conf for the shared namespace sets user specific CONTROL and INDEX locations so that users can independently subscribe to folders and mark messages as read on an individual basis. Many thanks, Stu.

That is not right, no matter what. There is definitely some issue. Once the load increases the system will start timing out on POP3 connections or other network connections, such as IMAP, SSH etc. Better check out the system logs, utilization etc. for any abnormal values.

[Dovecot] Quota_rules ignored
by A. Gideonse 24 Jun '09

24 Jun '09

Today I upgraded to version 1.1.16 of Dovecot (and Sieve), because I wanted to use mailbox quotas. I tried using the instructions on http://wiki.dovecot.org/Quota/1.1 and simular websites for 4 hours now, but it seems that all quota_rules are ignored. Also, whenever I use a '*' in my MySQL query I get the error: 'unknown quota backend'. With the following query the quota from the database is used (if value is not NULL), but the quota_rules are ignored once again: user_query = SELECT maildir AS home, 5000 AS uid, 5000 AS gid, CONCAT('maildir:storage=', quota) AS quota FROM mailbox WHERE username = '%u' Below is my configuration: # 1.1.16: /etc/dovecot/dovecot.conf # OS: Linux 2.6.24-19-virtual i686 Ubuntu 8.04.1 nfs log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s ssl_disable: yes disable_plaintext_auth: no login_dir: /usr/local/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 mail_privileged_group: mail mail_location: maildir:/data/vmail/%d/%n mail_debug: yes mmap_disable: yes dotlock_use_excl: no mbox_write_locks: fcntl 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_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota 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: mechanisms: plain login debug: yes passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: passwd userdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: static args: uid=5000 gid=5000 home=/home/vmail/%d/%n allow_all_users=yes socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: vmail plugin: quota: maildir:User quota quota_rule: *:storage=1G quota_rule2: .Trash:storage=100M Any thoughts on how to solve this problem?

[Dovecot] deliver does not update maildirsize
by ftriboix＠falcon-one.com 24 Jun '09

24 Jun '09

Hello, I have installed postfix 2.5.1 + dovecot 1.0.13 + MySQL and it all works perfectly. I use deliver as the local delivery agent and use IMAP only with maildir mailboxes. I am using virtual mailboxes. Now I wanted to introduce quotas, but I can't manage to make them work. Quota information is retreived from MySQL in userdb requests. I have noticed that the maildirsize file is not updated by deliver when a new mail comes in. I don't know if this is correct or not... It is updated though when I log in. But even then mails are still received without any kind of problem while the mailbox is well over the quota. I tried to add a "-v" option to deliver in postfix's master.cf to debug deliver, but it apparently does not like this option. Please find below my postfix and dovecot's configurations. Thank you very much for any help.

[Dovecot] Dovecot Problem
by Robert Sloan 24 Jun '09

24 Jun '09

Dear Sirs, I was able to migrate successfully from Courier-Imap to Dovecot, Timo I appreciate your help. I have notices that the file /var/log/dovecot.log shows the following: dovecot: Jun 23 15:04:05 Info: imap-login: Login: user=<dtoledo>, method=PLAIN, rip=172.16.10.15, lip=172.16.10.19 dovecot: Jun 23 15:04:06 Info: imap-login: Login: user=<abonilla>, method=PLAIN, rip=172.16.10.14, lip=172.16.10.19 dovecot: Jun 23 15:04:06 Info: IMAP(abonilla): Disconnected: Logged out bytes=59/566 dovecot: Jun 23 15:04:06 Info: imap-login: Login: user=<slopez>, method=PLAIN, rip=172.16.10.14, lip=172.16.10.19 dovecot: Jun 23 15:04:06 Info: IMAP(slopez): Disconnected: Logged out bytes=59/567 dovecot: Jun 23 15:04:06 Info: IMAP(dtoledo): Disconnected: Logged out bytes=1252/34481 dovecot: Jun 23 15:04:07 Info: imap-login: Login: user=<slopez>, method=PLAIN, rip=172.16.10.14, lip=172.16.10.19 dovecot: Jun 23 15:04:07 Info: IMAP(slopez): Disconnected: Logged out bytes=59/567 dovecot: Jun 23 15:04:07 Info: IMAP(framirez): Disconnected: Logged out bytes=1252/34041 dovecot: Jun 23 15:04:08 Info: imap-login: Login: user=<mgomez>, method=PLAIN, rip=172.16.10.14, lip=172.16.10.19 dovecot: Jun 23 15:04:10 Info: IMAP(mgomez): Disconnected: Logged out bytes=1805/66570 dovecot: Jun 23 15:04:13 Info: imap-login: Login: user=<curibe>, method=PLAIN, rip=172.16.10.14, lip=172.16.10.19 dovecot: Jun 23 15:04:15 Info: IMAP(curibe): Disconnected: Logged out bytes=749/351591 Given that there are several domains hosted on the server, how can I configure Dovecot to the log file shows the full user name.

[Dovecot] dovecot-antispam problem with sa-learn
by maxlosblob＠tiscali.it 24 Jun '09

24 Jun '09

Hi all, I just set up a dovecot+postfix+roundcubemail+spamassassin system with virtual users. These applications work fine, I have a problem with the dovecot-antispam plugin. Dovecot is compiled from tarball, version 1.1.16, the plugin is version 1.2. The problem is that when I move messages from or to "Posta indesiderata", which is in antispam_spam list, nothing happens. I have no logs about sa-learn activity in /var/log/maillog, nor in /var/log messages, no matter if I set DEBUG=syslog or DEBUG=stderr. Here are my confs: dovecot-antispam .config BACKEND=mailtrain USER=root GROUP=root DEBUG=syslog DEBUG_VERBOSE=5 PLUGINNAME=antispam dovecot -n # 1.1.16: /usr/local/etc/dovecot.conf # OS: Linux 2.6.18-sblob i686 CentOS release 5.2 (Final) simfs protocols: imap pop3 ssl_disable: yes disable_plaintext_auth: no login_dir: /usr/local/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 last_valid_uid: 500 first_valid_gid: 500 last_valid_gid: 500 mail_location: maildir:/var/virtual/%d/%n/Posta mail_debug: 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_plugins(default): listescape antispam mail_plugins(imap): listescape antispam mail_plugins (pop3): 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 namespace: type: private separator: / inbox: yes list: yes subscriptions: yes auth default: passdb: driver: sql args: /etc/dovecot-sql.conf userdb: driver: static args: uid=500 gid=500 home=/var/virtual/% d/%u plugin: antispam_trash: trash;Trash;Deleted Items;Cestino; antispam_spam: Spam;Posta indesiderata;.Posta indesiderata;SPAM;.SPAM antispam_mail_sendmail: /usr/bin/sa-learn antispam_mail_spam: --spam antispam_mail_notspam: --ham antispam_mail_tmpdir: /tmp Thanks in advance Max Non rinunciare ai tuoi ricordi...Tiscali Photo affronta la crisi con incredibili offerte http://photo.tiscali.it

[Dovecot] v1.2.rc6 released
by Timo Sirainen 24 Jun '09

24 Jun '09

http://dovecot.org/releases/1.2/rc/dovecot-1.2.rc6.tar.gz http://dovecot.org/releases/1.2/rc/dovecot-1.2.rc6.tar.gz.sig I think it's time to get v1.2.0 released soon. There is apparently still one rare crashing bug in virtual plugin, but unless someone can reproduce the bug I'm not going to delay v1.2.0 because of it. The release plan is: - Release v1.2.rc7 next Friday (assuming there have been some fixes) - Release v1.2.0 the next Monday I'll be giving a Dovecot talk in Berlin on July 2nd, and I really want to have v1.2.0 released by them. So July 1st is the absolute final deadline for v1.2.0. :) Changes since rc5: * imap proxy: Pass through to client unexpected untagged replies from remote server (e.g. alerts). * Solr: Don't use "any" copyfield, it doubles the index size. * mail_location: Allow using ":" characters in dir names by escaping it as "::". - mbox: Don't crash with invalid From_-lines. - IMAP: Don't crash if IDLE command is pipelined after a long-running UID FETCH or UID SEARCH. - ACL / shared mailbox fixes - Some metadata files were incorrectly getting 0666 permissions.

[Dovecot] courier-imap 2 Dovecot Migration
by Odhiambo ワシントン 24 Jun '09

24 Jun '09

I have a question about migration from courier-imap. I have a server running courier-imap which I'd like to change to dovecot. The problem at hand is that there are POP3 users as well as IMAP4 users.Some of the POP3 users have the option to "leave a copy of the message on the server" set in their MuAs. Is it possible to migrate from courier-imap --> Dovecot and not have these people re fetching all their old e-mails all over again? -- Best regards, Odhiambo WASHINGTON, Nairobi,KE +254733744121/+254722743223 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ "If you have nothing good to say about someone, just shut up!." -- Lucky Dube

[Dovecot] tcp_wrappers
by listmail 23 Jun '09

23 Jun '09

Hi, I've just started using Dovecot (v1.1.14), and I'm noticing a lot of dictionary attacks. I searched through the documentation and the mailing list archives hoping to find support for tcp_wrappers (hosts.deny) support. I did find some suggested patches in the list from last year, but as far as I can tell, there is no support in the released versions. Is this implemented and undocumented, or just unimplemented? I would be surprised to find it unimplemented in such an otherwise sophisticated project. Thanks in advance, --Bill

[Dovecot] A X-Mailbox header?
by Alessandro Ranellucci 23 Jun '09

23 Jun '09

Hi all, I'm waiting for the virtual mailbox feature in order to make a single POP3 access to retrieve messages contained in all my mailbox folders. This is because I use webmail and other IMAP clients but my main workstation uses a POP3-only client. I was wondering if there's a way to keep the name of the folder containing each message while retrieving via POP3. I guess this could be done by dynamically adding a header to messages at retrieval time. Is there a feature for this or a plugin API? Otherwise I was thinking about modifying the messages themselves on the server using a script. However, such a script would need to be run when a IMAP user moves a message to a folder and I believe Dovecot doesn't provide a trigger/hook mechanism. I also don't know if modifying stored messages is allowed since it could break some caching/hashing mechanism. Do you have any idea for this? Thanks in advance and thanks to Timo for the great work! - alessandro.

[Dovecot] CRAM-MD5 authentication but plain-md5 password storage.
by Richard 22 Jun '09

22 Jun '09

Hi all, Got a question on configuring dovecot, I'm still new at this so I might be doing this all wrong. I want dovecot to authenticate the mail client using CRAM-MD5 so I've setup the config in dovecot.conf: auth default { mechanisms = cram-md5 passdb sql { # Path for SQL configuration file, see doc/dovecot-sql-example.conf args = /etc/dovecot/dovecot-sql.conf } <snipped> } In my dovecot-sql.conf I've setup the password scheme to be: default_pass_scheme = MD5 Somehow this does not work, the error I see in the logfile is: auth-worker(default): password(info(a)richard5.tld,127.0.0.1): Requested CRAM-MD5 scheme, but we have only MD5 Is there a way to get this working or does this feature only works with passwords stored in plain text ? Thanks! Richard

[Dovecot] dedup in dovecot?
by Roy Sigurd Karlsbakk 22 Jun '09

22 Jun '09

Hi all Deduplicating data is not really a new thing, but quite efficient in mail systems where an email with an nMB attachment may be sent to multiple recipients. This might call for deduplicating data. Is there a way to do this, or is it far off? If I understand the system correctly, usually an MTA is calling dovecot on every single message, meaning the message itself won't necessarily be a duplicate in terms of headers (BCCs and so on). Would it be possible to dedup the content in terms of using separate files for the header and content and then deduping this with hard or symbolic links? Sorry if this is an old question, but I couldn't find anything about it. roy -- Roy Sigurd Karlsbakk (+47) 97542685 roy(a)karlsbakk.net http://blogg.karlsbakk.net/ -- I all pedagogikk er det essensielt at pensum presenteres intelligibelt.

[Dovecot] Dovecot v1.2 share user Maildir problems with %%h
by Steffen Kaiser 22 Jun '09

22 Jun '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, I'm using Dovecot v1.2 9133:f65112bd90b3 with attached config and try to share user Maildirs. The ACLs are working. However the %%h gives me head aches, well, the location in general: I've copied the default mail_location and changed its CONTROL and INDEX settings: namespace shared { ... location = maildir:%%h/Maildir:CONTROL=/var/cache/dovecot/%i/control/shared/%%u:INDEX=/var/cache/dovecot/%i/index/shared/%%u } Now the first wows are that: a) IMAP insists to connect to $install_prefix/var/run/dovecot/auth-master instead of /var/run/dovecot/auth-master used by deliver. My workaround was to symlink /var/run/dovecot/ to $install_prefix/var/run/dovecot/ b) This socket needs to be r/w for every user, which is a security risk as mentioned in the conf and the default permission is 0600. For deliver I changed the socket attr to permission 0660 and group=mail; for making %%h work I added mail_access_groups=mail c) The user's mailbox is not found still, because: 2009-06-17 15:04:57 auth(default): Info: master in: USER 1 testusr/INBOX service=internal 2009-06-17 15:04:57 auth(default): Info: auth(?): Invalid username: testusr/INBOX 2009-06-17 15:04:57 auth(default): Info: userdb(?): Username contains disallowed character: 0x2f 2009-06-17 15:04:57 auth(default): Info: master out: NOTFOUND 1 The imap process passes the mailbox to the authentificator, too. Also, it changes the '.' to '/', although rawlog has: select "shared.testusr.INBOX" If I allow "/" as userchar, I get: 2009-06-17 15:43:00 auth(default): Info: ldap(testusr/INBOX): Unknown user 2009-06-17 15:43:00 auth(default): Info: master out: NOTFOUND 1 It reallt requests the data of user "testusr/INBOX". d) If I use location = maildir:/home/%%u/Maildir: instead of %%h/Maildir, things work _except_ that some user's %%h != /home/%%u . ============== Basically I have yet another problem with location in the user-share namespace: Because one can override the default mail_location for each user, I did so for some users. Some of them even do not have the Maildir. That leads to the problem, that I need one shared namespace for each location template. There had been a suggestion of a special user-shared namespace a while back. How about to add the base location in the shared-mailboxes.db? So instead of "1" the value is the base of the shared location, e.g. maildir:/local/testuser or maildir:/home/user/Maildir..., and some %%? token takes the string from there. Because the path is known from the db now, the other problems mentioned above do no longer apply.

That is the problem, fetchmail just forwards it to port 25 (I think) and I need to work out what to put between fetchmail and dovecot in order to get the mail into the correct folders... And I am just going around in circles on this at the moment. Any hint would be appreciated! Thanks, Michael

[Dovecot] auth_cache multiple passwords ?
by Geoffroy Desvernay 22 Jun '09

22 Jun '09

Hi, First, thanks Timo and Stefan for this great IMAP/Sieve implementation... We are using 1.1.16+cmu_sieve/managesieve additions for now (following releases since ~ 1.0.1). We have a specific problem here with auth-cache: We use direct imap/sieve connection from different clients, using LDAP password: everything is fine. The problem appears with our webmail access using a web-SSO system (jasig's CAS), using one-time-tickets as password for imap connections (checked by pam_cas module for now). For a single webmail connection par login, it work, thanks to cache_key using client's IP. But for multiple use of the same login in the webmail, there are more than one 'password' valid at a time… What may be the 'correct' solution: - patching auth-cache.c (auth_cache_lookup function ?) - writing a different login backend ? - ??? Hope I'm clear enough… -- geoffroy desvernay Ecole Centrale de Marseille

[Dovecot] dovecot-acl file questions
by Steffen Kaiser 22 Jun '09

22 Jun '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, playing around with Dovecot's v1.2 ACLs I wondered about some things about the dovecot-acl files: + They are created within the Maildirs, as described in http://wiki.dovecot.org/ACL. But why? Shouldn't they belong to the CONTROL= directories? So it is more compatible with filesystem quota. + They have 0666 permissions, but all other files (e.g. when I create a new mailbox) have 0660 permissions. Are the permissions selected explicitly to allow "a"-right for other (system) users? + When one removes all rights, the size of the file drops to zero. The wasted space is no great deal; but how much processing is wasted if such file is present? I mean, the log says that the files are opened very regularily. Would it help to remove zero-size files?

[Dovecot] Corrupted index cache file issues (Corrupted physical size)

The maildirs are migrated from a previous courier server. I've tried searching the archives and can't find anything related to this error. Could someone shed some light on it? Other than the error messages, I'm not aware of anything being affected, but I'd like to be sure of it Some info about the configuration: Maildirs are accessed via NFS, related settings are mmap_disable: yes mail_nfs_storage: yes mail_nfs_index: yes lock_method: dotlock Regards, Brent

[Dovecot] dovecot and ntp: Fatal: Time just moved backwards
by Arno Wald 22 Jun '09

22 Jun '09

Hallo, I am running dovecot on a PC (a workstation) to have a mail client independent storage for my mails. Now I would like to have the system clock set correctly by using ntpd or ntpdate (using debian/sid). The problem is, that the PC is not online at boot time, but is set online on demand manually using "pon" to start the pppd later. So ntpd cannot sync the time on boot time before dovecot gets started. First I was using ntpdate that was started in ppp's if.up.d/ directory. This tool does set the time very hard instead of just slightly shifting some milliseconds. So dovecot did stop itself, reporting: "Fatal: Time just moved backwards by 118 seconds. This might cause a lot of problems, so I'll just kill myself now." So I have tried ntpd as I thought it shifts the time in smaller time deltas. But this takes much time (several seconds) when booting, giving up on all configured servers, because they are not reachable when booting (as going online later manually). This turns off ntp functionality because ntpd does think that all servers are unreachable for ever. (I have tried a command "dynamic" in ntp.conf but this did not change anything and ntpd reports it to be obsolete.) My idea now is to not start ntpd on system boot, but only on if-up. But this brings up the same fatal error of dovecot as ntpd seems to hardly set the time, too. The only idea I have left is to stop dovecot, start ntpd and then start dovecot again on if-up. Is there a more elegant way to use dovecot and ntpd on a manually dialed in PC? Thanks, Arno

[Dovecot] cross compiling (arm)
by Stephen Feyrer 21 Jun '09

21 Jun '09

Hi. I'm trying to cross compile dovecot. My desktop machine is an AMD64 box with bells and whistles. The ARM based machine is a network attached storage box. When I run "make" always get x86_64 binaries. My OS is Gentoo, so I have been able to build using emerge a variety of other programs from source. What am I doing wrong here. (Gentoo doesn't have Dovecot for the arm) I run: ./configure --prefix=/opt --target=armv5tel-softfloat-linux-gnueabi host=armv5tel-softfloat-linux-gnueabi --build=x86_64-pc-linux-gnu --cache-file=config.cache These are some values from config.cache which I think are pertinent: ac_cv_build=${ac_cv_build=x86_64-pc-linux-gnu} ac_cv_c_compiler_gnu=${ac_cv_c_compiler_gnu=yes} ac_cv_env_build_alias_set=set ac_cv_env_build_alias_value=x86_64-pc-linux-gnu ac_cv_env_host_alias_set= ac_cv_env_host_alias_value= ac_cv_env_target_alias_set=set ac_cv_env_target_alias_value=armv5tel-softfloat-linux-gnueabi acl_cv_path_LD=${acl_cv_path_LD='/usr/x86_64-pc-linux-gnu/bin/ld -m elf_x86_64'} lt_cv_path_LDCXX=${lt_cv_path_LDCXX='/usr/x86_64-pc-linux-gnu/bin/ld -m elf_x86_64'} lt_cv_sys_lib_dlsearch_path_spec=${lt_cv_sys_lib_dlsearch_path_spec='/lib /usr/lib /usr/local/lib //usr/lib32/opengl/nvidia/lib //usr/lib64/opengl/nvidia/lib /lib /usr/lib /lib64 /usr/lib64 /usr/local/lib64 /lib32 /usr/lib32 /usr/local/lib32 /usr/x86_64-pc-linux-gnu/lib /usr/lib/gcc/x86_64-pc-linux-gnu/4.3.2 /usr/lib/gcc/x86_64-pc-linux-gnu/4.3.2/32 /usr/lib/gcc/x86_64-pc-linux-gnu/4.2.3 /usr/lib/gcc/x86_64-pc-linux-gnu/4.2.3/32 /usr/lib/gcc/x86_64-pc-linux-gnu/4.1.2 /usr/lib/gcc/x86_64-pc-linux-gnu/4.1.2/32 /usr/lib64/nspr /usr/lib64/nss /usr/lib64/seamonkey /opt/blackdown-jdk-1.4.2.03/jre/lib/amd64/ /opt/blackdown-jdk-1.4.2.03/jre/lib/amd64/native_threads/ /opt/blackdown-jdk-1.4.2.03/jre/lib/amd64/classic/ /opt/blackdown-jdk-1.4.2.03/jre/lib/amd64/server/ /usr/kde/4.1/lib /usr/kde/4.1/lib64 /usr/kde/4.1/lib32 /usr/kde/4.2/lib /usr/kde/4.2/lib64 /usr/kde/4.2/lib32 /usr/lib64/qca1 /usr/lib64/qca2 /usr/lib/qt4 /usr/lib64/qt4 /usr/lib32/qt4 /usr/qt/3/lib /usr/qt/3/lib64 /usr/qt/3/lib32 /usr/games/lib /usr/games/lib64 /usr/games/lib32 /opt/flash-libcompat /usr/lib64/fltk-1.1 /usr/lib32/libstdc++-v3/ '} lt_cv_sys_lib_search_path_spec=${lt_cv_sys_lib_search_path_spec='/usr/lib/gcc/x86_64-pc-linux-gnu/4.3.2 /usr/lib64 /lib64 /usr/x86_64-pc-linux-gnu/lib'}

[Dovecot] 1.1.16 stops authenticating users after several days
by Juergen Obermann 19 Jun '09

Hello, we use dovecot v1.1.16 on two servers with Solaris 9. This week both suddenly stopped authenticating users. The first server was startet on Jun 2 and ran until Jun 18 and the other startet on Jun 3 and failed on Jun 15. Both generated then lots of error messages, three for every user that attemps to login, looking like that: Jun 15 08:35:23 minerva dovecot-auth[20831]: [ID 401707 user.error] open_module: /usr/lib/security/pam_unix_account.so.1 failed: ld.so.1: dovecot-auth: fatal: /usr/lib/security/pam_unix_account.so.1: open failed: No such file or directory Jun 15 08:35:23 minerva dovecot-auth[20831]: [ID 487707 user.error] load_modules: can not open module /usr/lib/security/pam_unix_account.so.1 Jun 15 08:35:23 minerva dovecot: [ID 107833 local0.error] auth-worker(default): pam(gp1071,134.176.2.89): pam_acct_mgmt() failed: Dlopen failure The file /usr/lib/security/pam_unix_account.so.1 was still there and had not been changed.

[Dovecot] compiling dovecot-1.2-sieve-0.1.5 with the latest dovecot-1.2.rc5
by Tim Traver 19 Jun '09

19 Jun '09

Hi all, ok, downloaded dovecot-1.2.rc5 and compiled it with no problem. Then, I went to compile the latest dovecot-1.2-sieve-0.1.5 with it, and got the following error : mail-raw.c: In function 'mail_raw_init': mail-raw.c:119: error: 'NAMESPACE_FLAG_INTERNAL' undeclared (first use in this function) mail-raw.c:119: error: (Each undeclared identifier is reported only once mail-raw.c:119: error: for each function it appears in.) *** Error code 1 In looking around, I noticed in a changed log dated last month, that the NAMESPACE_FLAG_INTERNAL was moved to be two separate flags "_NOQUOTA and _NOACL"... But I think that the author of dovecot-1.2-sieve-0.1.5 hasn't made the change to handle that... So, first of all, I guess I would just like to bring it to the authors attention if it hasn't been already, and second, what is the last rc version before that change so I can actually get things to compile? Thanks, Tim.

[Dovecot] quota.
by Mauro 18 Jun '09

18 Jun '09

Hallo. Sorry for may bad english. I'm running dovecot 1.0.15 on a debian lenny system. I've set quota plugin and, under section plugin, I've set: quota = maildir quota_rule = *:storage=50M quota_rule2 = Trash:storage=10%% quota_warning = storage=95%% /usr/local/bin/quota-warning.sh 95 quota_warning2 = storage=80%% /usr/local/bin/quota-warning.sh 80. For some accounts the quota limit works well. When I send mail I receive a rejected mail for quota exceeded. For some other accounts it doesn'work despite they have passed the 50M storage limit. Why?

[Dovecot] Question about "target is inferior" type of message
by Michael Durket 17 Jun '09

17 Jun '09

We're converting UW-IMAP users here to dovecot. Some of them have seen the error message issued when Thunderbird clients try to delete folders and I understand what's going on (from previous postings) that Dovecot doesn't support mbox subfolders within folders. What puzzles me is that many of these users already have folders within folders (I've found typically 2 levels of nested folders within their main Mail directory). And they're not complaining that they can't read the messages in those folders. If UW-IMAP supposedly never supported this for mbox format, and Dovecot doesn't support it, how is this possible under Dovecot? (We don't have any maildir format mailboxes here at all).

[Dovecot] enourmous amount of disc writes
by Rainer Sigl 17 Jun '09

17 Jun '09

Hi List, on my mailserver (exim4, dovecot 1.0.0, postgresql, ubuntu dapper, about 500 users) I record an enourmous amount of disc writes (up to 18000 blocks written each second) in the time where most of users are active. This IO activity causes wait-states on the disc interface (RAID5) and finally slows down my mailmachine. Is there a explanation for these disc writes respectively is there a possibility to minimize this activity. Stopping Dovecot on this machine causes stopping most of the disc activity.

[Dovecot] v1.2.rc5 imap ignores configuration reloads

Hi Timo, after changing the mail_executable in the imap {…} section I have to restart Dovecot v1.2.rc5, otherwise the changes are not accepted. With Dovecot v1.1.x (tested with v1.1.11 and v1.1.16) it's enough to send a SIGHUP to the dovecot process. Regards, Pascal -- The trapper recommends today: c01dcofe.0916521(a)localdomain.org

[Dovecot] Authentication cache, failure to login after changed password
by Tom Sommer 16 Jun '09

16 Jun '09

Hi, I have an issue with the authentication cache. When a user changes his password, the cache doesn't seem to get flushed. Meaning the user is unable to log in to his IMAP account after changing his password. Flow: - Log into IMAP account using pass1 - Approved - Stored in auth cache - Change password to pass2 in MySQL - Log into IMAP account using pass2 - Access is denied - Restart dovecot - Log into IMAP account using pass2 - Approved I'd really like to continue to use the auth cache, is there any solution to the above? perhaps a way to debug the cache and auth process? I wasn't able to activate auth_debug without restarting Dovecot and solving the problem. Using version 1.1.1, MySQL userdb, with "nopassword=Y". Maybe it's due to nopassword? Thanks -- Tom

[Dovecot] LAYOUT=fs vs LAYOUT=maildir++ and quota
by Ezequiel Alfíe 16 Jun '09

16 Jun '09

Hi everyone. I'm confused about LAYOUT=fs... Does using LAYOUT=fs breaks maildir++ quota, if I use this quota scheme? What are the advantages anyway of using LAYOUT=fs vs LAYOUT=maildir++ ? (it's not important in my case if users can't create folders with dots '.') Thanks in advance, Ezequiel
