[Dovecot] On-delivery deduplication?
by Xin LI 10 Jun '11

10 Jun '11

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hi, A feature of Cyrus-IMAPd I really missed after migrated to Dovecot is their optional "duplicate suppression", which eliminates duplicate message at deliver time, if their envelope sender, recipient and message-id matches. For example, if one subscribes to a mailing list, and someone hit "Reply All" to reply to him, there will be two different SMTP deliveries, one from the replier's server and one from the mailing list. Is it possible to do the same on latest Dovecot? (Looking at the documentation it seems not?) Or is there some better ways to implement the same functionality? Thanks in advance!

[Dovecot] possible bug leading to lmtp crashes
by Trever L. Adams 10 Jun '11

10 Jun '11

I have been using Samba 4 kerberos and ldap with dovecot. Samba 4 changed a while back (resulting in me asking for help) which requires kerberos auth for ldap lookups. My setup worked perfectly before hand. Before and after were with dovecot-2.0.11 and the after also happens with 2.0.11. The only changes were (in my ldap.conf for dovecot -- changes are new lines starting with *, * is not in the conf, just showing changes): hosts = example.org base = dc=example,dc=org ldap_version = 3 user_attrs = userPrincipalName=user user_filter = (&(objectClass=person)(|(mail=%u)(sAMAccountName=%u)(userPrincipalName=%u))) *dn = MACHINEACCOUNT$(a)EXAMPLE.ORG *sasl_bind = yes *sasl_mech = GSSAPI *sasl_realm = EXAMPLE.ORG *#sasl_authz_id = MACHINEACCOUNT$(a)EXAMPE.ORG # For using doveadm -A: iterate_attrs = userPrincipalName=user iterate_filter = (objectClass=person) in dovecot.conf: import_environment = TZ KRB5CCNAME=/etc/dovecot/krb5.cc With that do any of the following lines from the referenced hg rev set mean I am missing anything on my import_environment variable? Or is it all good? 10.15 +/* <settings checks> */ 10.16 +#ifdef HAVE_SYSTEMD 10.17 +# define ENV_SYSTEMD " LISTEN_PID LISTEN_FDS" 10.18 +#else 10.19 +# define ENV_SYSTEMD "" 10.20 +#endif 10.21 +#ifdef DEBUG 10.22 +# define ENV_GDB " GDB" 10.23 +#else 10.24 +# define ENV_GDB "" 10.25 +#endif 10.26 +/* </settings checks> */ 10.27 + 10.28 static const struct master_settings master_default_settings = { 10.29 .base_dir = PKG_RUNDIR, 10.30 .libexec_dir = PKG_LIBEXECDIR, 10.31 + .import_environment = "TZ" ENV_SYSTEMD ENV_GDB, If I am not missing anything, then there seems to be a problem with kerberos sasl with ldap lookups.

[Dovecot] IMAP Label Updates not showing up across shared account
by Ricardo Branco 09 Jun '11

09 Jun '11

Dovecot 2.0.13 Centos 5.4 x86_64 2.6.18-164.9.1.el5 (on ESXi) OS/Logs on local storage, /home all on NFS server for datastore (NFS Store Centos 5.5 x86_64 2.6.18-194.11.1.el5) Thunderbird 3.1.10 on XP/W7 Desktops We are seeing a werid issue where there is a delay of up to a few mins in seeing label updates on messages. I have confirmed that Thunderbird is sending the update to the server with WireShark, its just additional users connected to the same mailbox do not see them. Marking a message as Seen/Un-Seen happens faster just not labels. If you have a label set when you mark a message as Seen/Un-Seen the other clients then see the update straight away. -- The information contained in or attached to this email is intended only for the use of the individual or entity to which it is addressed.

Hi I migrated to dovecot 2 and I started using lmtp for mail delivery. But I have found this on my logs "save failed to INBOX: Not enough disk space" . There is enougth space on disk. and I am not using quota plugin on lmtp my lmtp conf is as follow: # ## LMTP specific settings ## # Support proxying to other LMTP/SMTP servers by performing passdb lookups. #lmtp_proxy = no # When recipient address includes the detail (e.g. user+detail), try to save # the mail to the detail mailbox. See also recipient_delimiter and # lda_mailbox_autocreate settings. #lmtp_save_to_detail_mailbox = no protocol lmtp { # Space separated list of plugins to load (default is global mail_plugins). #mail_plugins = $mail_plugins mail_plugins = sieve postmaster_address = admin(a)domain.tld } Any idea please? Thanks

[Dovecot] deliver doesn't find adress/inbox
by Martin Benkenstein 08 Jun '11

08 Jun '11

I'm trying to make dovecot 1.2.15, deliver, openLDAP, exim and fetchmail work together on an Debian Squeeze (virtual) maschine. The connection between dovecot and LDAP seems to be working, I can logon from Thunderbird (IMAP) and my maildir is created automatically. So far so good. But when I download the mails via fetchmail, it seems that deliver cannot find the correct mailbox for the X-Envelope-To entry in the header. fetchmail downloads all mails for the domain from one account (config below) and hands them over to exim. I configured exim addording to the wiki entry (http://wiki.dovecot.org/LDA/Exim Virtual Users / Single UID). The mail is sent back to the account which is fetched by fetchmail. There is a header entry X-Fetchmail-Warning: no recipient addresses matched declared local names. The fetchmail-log itself is worthless. What am I doing wrong? At which does the system try to look up the mailaddress and fails?

[Dovecot] How Dovecot 2 create folders and subfolders ( MBOX format ) with TB ?
by Frank Bonnet 07 Jun '11

07 Jun '11

Hello When creating new IMAP folder with thunderbird and Dovecot configured with the std MBOX format dovecot create a file in mbox format and so it is not possible to create a subfolder of this folder. If you ask to create a NEW subfolder of the form : TOTO/TATA Dovecot create a directory TOTO containing a mbox file TATA. Very useful :-) I suppose the "/" separator is parsed by dovecot then it creates a directory containing the mbox file. Am I right ?

Hi, I was wondering if anyone might be able to help me with this. I am running Postfix 2.7.0, Dovecot 1.2.9 and squirrelmail. Every week, I perform a back-up on both Postfix and Dovecot (maildir and conf folders). That's good because I have all the emails backed up. And now what I would like to ask is whether or not there are any easy way of restoring e-mails if some emails got deleted by accident or for other reason. So far, I have tried to look up the answer on the Internet but got a bit of vague answer. Any help would be greatly appreciated. Thank you

I'm running Dovecot 1.2.15 as an IMAP server on an up-to-date Debian v6 VM. I've recently upgraded the server from a pretty crusty old Debian v4 installation, though I don't recall exactly which version of Dovecot that would have been running. I guess I could try crawling through the old logs to check if it is likely to be useful. The upgrade seemed to have gone fine and I've been using the new server for about a week, but this morning I'm finding that whilst I can successfully connect to the IMAP server using Mutt, it can't display a mail index and a quick peek at the logs shows the IMAP process falling over: (account and server IP replaced) Jun 6 10:39:27 xen dovecot: Dovecot v1.2.15 starting up (core dumps disabled) Jun 6 10:39:27 xen dovecot: auth-worker(default): mysql: Connected to localhost (mail) Jun 6 10:39:34 xen dovecot: imap-login: Login: user=<example(a)example.org>, method=PLAIN, rip=::1, lip=::1, TLS Jun 6 10:39:35 xen dovecot: IMAP(example(a)example.org): Panic: file mail-index-view.c: line 264 (view_lookup_seq_range): assertion failed: (first_uid > 0) Jun 6 10:39:35 xen dovecot: IMAP(example(a)example.org): Raw backtrace: imap() [0x80f0e1e] -> imap() [0x80f0e82] -> imap() [0x80f0809] -> imap() [0x80ceb17] -> imap(mail_index_lookup_seq+0x26) [0x80ce5f6] -> imap() [0x80c481d] -> imap(mail_index_modseq_hdr_update+0x2e) [0x80c48ee] -> imap(mail_index_sync_ext_hdr_update+0xbb) [0x80de91b] -> imap(mail_index_sync_record+0x40f) [0x80cd57f] -> imap(mail_index_sync_map+0x2dd) [0x80cdfed] -> imap(mail_index_map+0x5c7) [0x80c3557] -> imap() [0x80bfd87] -> imap(mail_index_open+0x23f) [0x80c01ff] -> imap(index_storage_mailbox_open+0x71) [0x80abc81] -> imap(maildir_storage_sync_init+0x188) [0x8086c18] -> imap(mailbox_sync+0x31) [0x80b59d1] -> imap(imap_status_get+0x8a) [0x806f0ea] -> imap(cmd_status+0x123) [0x8065dd3] -> imap() [0x8067b5c] -> imap() [0x8067c32] -> imap(client_handle_input+0x175) [0x8067eb5] -> imap(client_input+0x5f) [0x80686ef] -> imap(io_loop_handler_run+0xd6) [0x80f9aa6] -> imap(io_loop_run+0x20) [0x80f8f20] -> imap(main+0x5b4) [0x8070f24] -> /lib/i Jun 6 10:39:35 xen dovecot: IMAP(example(a)example.org): 76] -> imap() [0x80603a1] Jun 6 10:39:35 xen dovecot: dovecot: child 20617 (imap) killed with signal 6 (core dumps disabled) I've not been able to find any mentions of this error occurring for other people.

Hi all, I'm not so sure it is about to dovecot, but any thoughts will be appreciated. I have an email account configured as IMAP(dovecot-1.2.10) via outlook 2010.

[Dovecot] file rights for dictionary file
by Michael Köhler 06 Jun '11

06 Jun '11

Hi, I use Debian Squeeze and the sources from Stephan Bosch. A few weeks ago I´ve upgraded from 2.0.11 to 2.0.13 and got an error May 29 20:01:53 mailserver dovecot: dict: Error: Can't open configuration file /etc/dovecot/dovecot-dict-sql.conf.ext: Permission denied May 29 20:01:53 mailserver dovecot: dict: Error: Failed to initialize dictionary 'quota' and I could see that /etc/dovecot/dovecot-dict-sql.conf.ext is owning by root:root with 600. After changing to root:root 644 all works, but after each upgrade all files in /etc/dovecot will be set to 600. Is it a problem of the dovecot package or should I do some changes to config to allow dovecot reading the dict file?

[Dovecot] Bug: Fixed a duplicate
by Tom Sommer 06 Jun '11

06 Jun '11

I restored a dovecot mailserver today, and when I started the server again, the logs filled up with "Fixed a duplicate" warnings. This in itself it not a problem, the problem is that it appears the fix is not done correct. Consider this: Warning: Fixed a duplicate: [X]/cur/1305907573.V807I37682f3M146183.mail8.xxx.com:2,S -> 1306601066.M382668P27710.mail8.xxx.com The problem appears to be the timestamp of this new file isn't updated correctly. Now I got hundreds of mailboxes filled with mails named 1305907573.* with random (in the past) timestamps, leading to mangled miss-sorted inboxes for customers. 3575 May 25 02:05 1306600913.M982997P26976.mail8.xxx.com:2,S 55313 May 6 01:50 1306600913.M982998P26976.mail8.xxx.com:2,S 9839 May 7 23:59 1306600913.M982999P26976.mail8.xxx.com:2,S 3453 May 10 01:32 1306600913.M983000P26976.mail8.xxx.com:2,S 16616 May 14 00:22 1306600913.M983001P26976.mail8.xxx.com:2,S 68850 May 25 00:46 1306600913.M983002P26976.mail8.xxx.com:2,S etc. Dovecot is v. 2.0.11 I guess I should have deleted all dovecot.* files after the restore, before I started dovecot? // Tom

[Dovecot] Custom sql query for keeping quota with dict-sql
by Marcin Mirosław 05 Jun '11

05 Jun '11

Hello! I'd like to setup quota for for virtualusers, i'm using both maildir++ and mdbox as storage, and i'm using postgresql to keep users. I'm keeping all users data in one table: [...] login text NOT NULL, domain text, password text, quota_mb integer NOT NULL DEFAULT 0 [... other columns ...] i'd like to keep present quota in such two columns: quota_dict_bytes integer NOT NULL DEFAULT 0, quota_dict_messages integer NOT NULL DEFAULT 0 I read wiki a little and it looks i can't define own sql queries, they appear to be hardcoded. Am i wrong? Is it possible to write own queries to get/set quota using such table schema? Or maybe there is diffrent way to track quota for diffrent storages? Regards! Marcin

[Dovecot] solr substring schema.xml
by Daniel Miller 03 Jun '11

03 Jun '11

I'm trying a modified schema.xml with solr - it appears I now have substring searches! I took the schema.xml file shipped with Dovecot, and modified the text field definition to be: <fieldType name="text" class="solr.TextField" positionIncrementGap="100"> <analyzer type="index"> <tokenizer class="solr.WhitespaceTokenizerFactory"/> <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt"/> <filter class="solr.WordDelimiterFilterFactory" generateWordParts="1" generateNumberParts="1" catenateWords="1" catenateNumbers="1" catenateAll="0"/> <filter class="solr.LowerCaseFilterFactory"/> <filter class="solr.SnowballPorterFilterFactory" protected="protwords.txt"/> <filter class="solr.NGramFilterFactory" minGramSize="3" maxGramSize="15"/> <filter class="solr.RemoveDuplicatesTokenFilterFactory"/> </analyzer> <analyzer type="query"> <tokenizer class="solr.WhitespaceTokenizerFactory"/> <filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" ignoreCase="true" expand="true"/> <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt"/> <filter class="solr.WordDelimiterFilterFactory" generateWordParts="1" generateNumberParts="1" catenateWords="0" catenateNumbers="0" catenateAll="0"/> <filter class="solr.LowerCaseFilterFactory"/> <filter class="solr.SnowballPorterFilterFactory" protected="protwords.txt"/> <filter class="solr.RemoveDuplicatesTokenFilterFactory"/> </analyzer> </fieldType> Changing to the new "SnowballPorter" instead of the deprecated "EnglishPorter" filters is probably minor - the magic is the "NGramFilterFactory". 3 & 15 seemed reasonable defaults for the min/max size to search on. -- Daniel

[Dovecot] unexpected subfolder locaton in Maildir/.INBOX.subfolder
by wulf 03 Jun '11

03 Jun '11

Hallo, I try to migrate existing imap server to dovecot 1.2 in debian squeeze if I connect to imap://user@host/INBOX Inbox works as expected and I get the content of Maildir/{cur,new,tmp} Maildir/.subfolder already exists if I connect to imap://user@host/INBOX.subfolder I get "folder not found" if I do a imap directory listing (raw mutt config, no subscriptions) - I see "../" - If I navigate to "../" I se all my existing subfolders if I create a new folder via imap the folder is created in Maildir/.INBOX.new_subfolder I expect the creation of Maildir/.new_subfolder This doesn't fit to the client configs and if I move the existing folders it doesn't fit to existing delivery agent filters and settings. I enabled mail_debug and the expansion looks ok for me: dovecot: imap-login: Login: user=<wulf>, method=PLAIN, rip=85.178.xx.xxx, lip=80.81.xxx.xxx, TLS dovecot: IMAP(wulf): Effective uid=112, gid=114, home=/var/mail/home/wulf dovecot: IMAP(wulf): maildir: data=~/Maildir dovecot: IMAP(wulf): maildir++: root=/var/mail/home/wulf/Maildir, index=, control=, inbox=/var/mail/home/wulf/Maildir the existing subscription information from courier-imap looks like INBOX.subolder Yes I can sed them to subfolder (of course I have to copy them to Maildir/subscriptions anyhow) But is that the idea?

[Dovecot] Running a dovecot cluster with mixed versions?
by Ian Foutch 03 Jun '11

03 Jun '11

I have been trying to find information and possible issues with running a cluster of dovecot server with different versions without any luck. We have an existing cluster with dovecot v1.1.10 and tried migrating to a new cluster with dovecot v2.0.12. We ran into some issues when we moved traffic to the new cluster and have been unable to reproduce it in our own testing. We may need to put real usage on the new servers but would like to be able to do this by adding newer servers into the existing cluster. What are the potential issues with doing this?

[Dovecot] Problems in auth when switching from PLAIN-MD5
by Eduardo Casarero 03 Jun '11

03 Jun '11

Hi, i am running dovecot 2.0.11 (with mysql backend) and until now using PLAIN-MD5 as pass default_pass_scheme everything was working fine. However i wanted to change the pass_scheme to something stronger than plain-md5, so i started by reading the wiki. I found this: http://wiki2.dovecot.org/HowTo/ConvertPasswordSchemes But when i comment out "default_pass_scheme" and i create the pass with the {SHA256.hex} prefix i see this in the logs: auth: Error: sql(xxx(a)xxxxxx.com,10.21.1.1): Password in passdb is not in expected scheme SHA256.hex I tried with several algorithms, but it seems to be something in my config that it's only working with plain-md5. the auth_mechanism is plain with ssl/tls. Maybe someone can give me a hint of where to see o which config file review. Thanks in advance. Eduardo.

Hi all, ive been playing with squat indexes. Up to about 300.000 emails in a single mailbox this was working flawlessly. The search index file is about 500MB at that time. Ive now added some more emails, and at 450.000 or so emails im seeing a serious problem with squat index creation. It takes...f o r e v e r . The .tmp file is being so slowly, it will probably take 2-3 hours to create. Upto this point it took maybe a minute. Im doing this in an openvz container, so theoretically i may be hitting some openvz resource limit. But ive upped all the limits and dont see any improvements. I dont see any resources starvation either. Could there be some dovecot issue when the search index reaches say 1GB? (im estimating that it's now trying to save about 1GB search index). Regards, Cor

Hi All, I need your help to limit the size of the Trash folder. I want to exclude the Trash folder in my user quota. But I do not want the Trash folder can not exceed 10M for example. I can manage to exclude the size of the Trash folder. But I can not limit the size of the folder. On my test, I've bytes=512000 for the Trash folder. But the user can move more that 512000B on the Trash folder ... Could you help me please ?

[Dovecot] Error: file_dotlock_create failed: Permission denied
by M. Fioretti 03 Jun '11

03 Jun '11

Hi, I have a Fedora 14 x86_64 computer. I run dovecot 2.0.12 on it, only to keep a local imap copy of all my email, in maildir format. A couple days ago the hard disk broke, so I bought a new one, and reinstalled Fedora 14 x86_64 with all the updates. Then I copied all the maildirs from a backup to the new drive. But I can't access email now. No matter how I change sticky bits or ownership and permissions of all the involved files and directories, etc.. Login succeeds, but I get this error whenever I try to create new mailboxes or access existing ones: May 25 13:36:03 polaris dovecot: imap-login: Login: user=<marco>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=8489, secured May 25 13:36:06 polaris dovecot: imap(marco): Error: file_dotlock_open(/home/z/email/marco/dovecot.index.log) failed: Permission denied (euid=500(marco) egid=500(marco) missing +w perm: /home/z/email/marco, euid is not dir owner) May 25 13:36:06 polaris dovecot: imap(marco): Error: file_dotlock_create(/home/z/email/marco/dovecot-uidlist) failed: Permission denied (euid=500(marco) egid=500(marco) missing +w perm: /home/z/email/marco, euid is not dir owner) May 25 13:36:06 polaris dovecot: imap(marco): Error: file_dotlock_create(/home/z/email/marco/dovecot-uidlist) failed: Permission denied (euid=500(marco) egid=500(marco) missing +w perm: /home/z/email/marco, euid is not dir owner) May 25 13:36:06 polaris dovecot: imap(marco): Error: opendir(/home/z/email/marco/new) failed: Permission denied (euid=500(marco) egid=500(marco) missing +r perm: /home/z/email/marco/new, euid is not dir owner) May 25 13:36:06 polaris dovecot: imap(marco): Error: file_dotlock_create(/home/z/email/marco/dovecot-uidlist) failed: Permission denied (euid=500(marco) egid=500(marco) missing +w perm: /home/z/email/marco, euid is not dir owner) Again, this doesn't change changing ownership. Output of dovecot -n is below The only possible difference I can find between this and the previous install of the SAME distro/dovecot package is that this time I use ext4 filesystem.

[Dovecot] Squat Question!
by Henrique Fernandes 03 Jun '11

03 Jun '11

Hello folks, I use dovecot squat for indexing. I use to have fts_squat = partial=4 full=4 But i change to fts_squat = partial=4 full=8 My question is, do i need to delete older indexes to have it consistenly, or dovecot is able "update" the indexes or it sees that it is broken and rebuild it all? Other question, is there an comand line to update the indexes ? Thanks a lot! []'sf.rique

[Dovecot] This is appear a fts bug
by Antonio Perez-Aranda 03 Jun '11

03 Jun '11

I have checked this on dovecot 2.0.9 and 2.0.13 with fts-solr without patching. If you execute the follow IMAP script, then the imap process die by and a "assert" . select "inbox." . search text something After search, the connection is aborted in the client side, and imap process died on the server. When the log in dovecot says: (fts_backend_solr_init): assertion failed: (*box_name != '\0') After debug the code, there isn't in context any possibility to get "box_name". With squat plugin it is running. -- Antonio Pérez-Aranda Alcaide aperezaranda(a)yaco.es Yaco Sistemas S.L. http://www.yaco.es/ C/ Rioja 5, 41001 Sevilla Teléfono +34 954 50 00 57 Fax +34 954 50 09 29

[Dovecot] shared folders "invisible" on new setup
by Torsten Harenberg 03 Jun '11

03 Jun '11

Dear list, I hope this is not an old issue, but I couldn't find a solution even after google'ing quite some time. I try to migrate our institute's mail server (~200 users) from an old cyrus-based Mac installation to a new machine (NetBSD, dovecot 2.0.13). Everything went quite smoothly so far, but we are used to have "shared folders" ("public" folders in dovecot) and I simply couldn't make them to appear. I have two separate folders for private (user) mails and for public ones (yes, I set everything to 777 for the moment to avoid file access problems) : mailserver# pwd /var/mail mailserver# ls -al total 8 drwxrwxrwt 4 dovecot wheel 512 May 31 12:26 . drwxr-xr-x 28 root wheel 512 Mar 29 15:05 .. drwxrwxrwx 3 root mail 512 May 31 15:18 public drwxrwxrwx 4 root wheel 512 May 31 12:26 user In the public folder there is a shared folder named "fb8": mailserver# pwd /var/mail/public mailserver# ls -al total 8 drwxrwxrwx 3 root mail 512 May 31 15:18 . drwxrwxrwt 4 dovecot wheel 512 May 31 12:26 .. -rw-rw-rw- 1 10001 mail 0 May 31 15:14 dovecot-acl-list -rwxrwxrwx 1 root mail 0 May 31 11:06 dovecot-shared drwxrwxrwx 5 root mail 512 May 31 12:03 fb8 Now my own username (LDAP-based) is "harenber" and I try to subscribe myself to this list: mailserver# doveadm mailbox subscribe -u harenber public.fb8 mailserver# So a "subscriptions" file appears: mailserver# ls -al total 8 drwxrwxrwx 3 root mail 512 May 31 15:18 . drwxrwxrwt 4 dovecot wheel 512 May 31 12:26 .. -rw-rw-rw- 1 10001 mail 0 May 31 15:14 dovecot-acl-list -rwxrwxrwx 1 root mail 0 May 31 11:06 dovecot-shared drwxrwxrwx 5 root mail 512 May 31 12:03 fb8 -rw-rw-rw- 1 10001 mail 4 May 31 15:18 subscriptions mailserver# cat subscriptions fb8 mailserver# (although I think this is wrong, as I have namespace { list = children location = maildir:/var/mail/public:INDEX=~/public prefix = public. separator = . subscriptions = no type = public } I would assume this file to appear somewhere in /var/mail/user/harenber/public... ) But I cannot access this "fb8" folder with any client.

[Dovecot] Dovecot 2 + Director: IMAP+GSSAPI and LMTP-proxying
by Jahnke-Zumbusch, Dirk 03 Jun '11

03 Jun '11

Hi all, I have a setup of some nodes running Dovecot 2.0.13 and Postfix 2.5.6 with storage in NFS and authentication happening with PAM. Poking around in the wiki, I tried out different possibilities but now I am stuck -- and are hoping for your (enlightening) comments and tips. My planned setup for IMAP and LMTP is like this: IMAP ==== 1. A loadbalancer directs new sessions to a Dovecot-Director instance; this extra amount of traffic routing is mostly done for automatic handling in case of a failing Director node; this works fine, the same IP will end always on the same backend, but user-based Directory proxying seems more appropriate, especially taking the NFS-setup and the delivery process into account 2. Then the Director decides where to direct the user's session; this works fine when I let the backend servers do the authentication work 3. The backend Dovecot server will happily provide the user's e-mail For now my section for the passdb in the Director instance is passdb { driver = static args = proxy=y nopassword=y } So the backend will do the authentication of the session. But this setup inhibits using Kerberos, as the TGT is not forwarded to the backend server. I would very much like to provide GSSAPI/Kerberos authentication, which already works fine with the backend servers being directly connected by mail clients. The backend servers are using the PAM driver. I could not figure out, how to setup the passdb entry for the director instance to use PAM (this way enabling GSSAPI/Kerberos) and also giving back the necessary "proxy=y" to make director proxying the IMAP session. Is this setup feasible at all? LMTP ==== 1. Postfix accepts incoming e-mail and decides, which e-mail will go the LMTP-way to be deliverd into a Dovecot mailbox with something like virtual_transport = lmtp:inet:DOVECOT-DIRECTORS-IP:LMTP-PORT-ABC 2. the Dovecot Director instance accepts the LMTP connections and will proxy this to the appropriate==user's current backend server For now Postfix delivers e-mails using LMTP to the _backend_ w/o proxying and everything like SIEVE-filtering works fine: virtual_transport = lmtp:inet:DOVECOT-BACKENDS-IP:LMTP-PORT-XYZ But when I use the Director's IP/Port combination for LMTP, I see an error "554 5.4.6 <the(a)addr.ess> Proxying loops to itself". Where may I specify the port number of the backend server's LMTP-port? I suspect that the missing port number implies that the receiving LMTP-backend server uses the same port and so this would lead to a loop, hence the loop error?! I browsed the Wiki and the archives but still cannot find the information I am looking for. Any hints on that?

[Dovecot] doveadm "-S <socket_path>" option enabled in 2.0.8?
by David Warden 03 Jun '11

03 Jun '11

I apologize if this is a stupid question but I just compiled 2.0.8 and am trying to use doveadm to get the quota for a user using the -S <socket_path> option because I have different options for the various local IPs that dovecot listens on. For example, my default quota is filesystem (NFS rquota) and I can get that by doing: doveadm quota get -u warden which tells me: Quota name Type Value Limit % User quota STORAGE 1313476 1766400 74 But when I try to get my quota on a different local IP using the -S flag to doveadm: doveadm quota get -u warden -S 137.238.2.244:143 I am told: get: invalid option -- S The strange thing is doveadm's usage says that the -S option is valid for quite a few commands and in the man pages for those commands it looks like they should work for the way I'm calling doveadm. In the 2.0.8 source I also see code that looks like it should be parsing the -S flag. I can telnet to 127.0.0.1:143 and do ". getquotaroot inbox" which gives me the same information as "doveadm quota get -u warden" and I can telnet to 137.238.2.244:143 and ". getquotaroot inbox" also tells me my quota, but I'm hoping to use doveadm to periodically recalc my Maildir++ quota and update the squat FTS indexes and for that to happen doveadm needs to be able to be told what local IP address/port to connect to (I think).

[Dovecot] [dovecot] notifications when delivery fails
by Héctor Moreno Blanco 03 Jun '11

03 Jun '11

Hello Timo, We have dovecot 1.2.13. Is there any way to send notifications to the postmaster when a delivery fails? For example, when the dovecot index are corrupted and the mail is not sent to the user (the user who sent the message receives an error informing that the mail has not sent). Thank you very much in advanced.

[Dovecot] 2.0: deliver run from multiple uids and configuration files
by Arkadiusz Miskiewicz 03 Jun '11

03 Jun '11

I'm trying to run deliver from exim transport in a way that it doesn't need to query userdb AND doesn't need to read configuration files. The problem is that config files are readable for root only and if I run deliver with multiple UIDs then I would have to allow reading config files for everyone. Of course that's not a option because configs contain database passwords and such stuff. I wonder if it is possible to avoid reading config files by deliver? The only solution I see it to run deliver via sudo which doesn't look nice. -- Arkadiusz Miśkiewicz PLD/Linux Team arekm / maven.pl http://ftp.pld-linux.org/

[Dovecot] LMTP/Sieve/sendmail path
by Andreas Schulze 03 Jun '11

03 Jun '11

Hello, I have a system using postfix multi instance feature. The first, main postfix-instance is a nullclient as suggested by http://www.postfix.org/MULTI_INSTANCE_README.html#split The second instance is for real use. Postfix receive mail and handover them to the dovecot lmtp server. Thats working. The lmtp server supports sieve. One account has activated a vacation rule. So while delivering a mail to this account, dovecot creates a new mail based on the vacation rules. *This one* fail. It is injected in the main postfix instance, which is wrong in this case. I tried to start dovecot with an additional environment MAIL_CONFIG=/etc/postfix-instance2 and enabled alternate_config_directories in main.cf of the first insance. ( http://www.postfix.org/postconf.5.html#alternate_config_directories ) I also configured the userdb to return an extrafield userdb_mail_config=/etc/postfix-instance2. But all produce strance postfix errors I never saw in my last 6 years as postfix-admin. Would it be possible to configure dovecot lmtp server to use an external smtp-server to submit new mails ? Any other Ideas ?
