[Dovecot] Managing public folder ACL files
by Keith Edmunds 14 Nov '11

14 Nov '11

We have a customer with a large public folder hierarchy. They occasionally make requests to have the public folder ACLs changed; for example: "please give user X access to all public folders" (that's nearly 1700 folders). Worse: "please give user Y access to all sales folders" (there are 1450 sales folders). The problem is that there are (naturally) spaces in the folder names, which makes command line manipulation challenging. We've ended up with some astonishingly hacky Python scripts that enter each folder starting with (for example) ".sales" and replacing the dovecot-acl file to try to fulfil the above requests. One day our script are going to get it wrong, or requests will become more complex ("give X access all sales/CustA folders, Y access to all sales/CustB folders, and Z access to all sales folders). There must be a Better Way. How do others manage divergent ACLs within large public folder hierarchies? Thanks, Keith

[Dovecot] Dovecot 1.2, problem with SQL quota and mail aliases
by Jacek Osiecki 22 Sep '11

22 Sep '11

Hello, I have a small server running dovecot 1.2 (still not balsy enough to switch to 2.0 - virtual sql accounts, managesieve etc.). There are no local users - only ones defined in the SQL database, and everything else (including quota) is defined in SQL db too. Dovecot is used as IMAP daemon, and dovecot-lda is responsible for delivery (in order to make use of sieve and managesieve). I know that my configuration might be a bit ancient, but this is not referring to any bug (at least I think so) and rather to errors I've made in configuration. Several users have reported, that they are running out of quota even though their mailboxes are empty. I thought these were some single cases, but recently I discovered that this situation occurs when: - user john(a)domain.com has a mail alias, eg. john.smith(a)domain.com - he logs in to the imap account (using MUA or webmail) using his alias (john.smith(a)domain.com). In effect, all incoming emails for john(a)domain.com are increasing the counters (both "bytes" and "messages"), but since user logs in using john.smith(a)domain.com - anything he deletes from the mailbox decreases the records for john.smith(a)domain.com. Finally, John has two records: +---------------------------+-----------+----------+ | username | bytes | messages | +---------------------------+-----------+----------+ | john.smith(a)domain.com | -5488133 | -13 | | john(a)domain.com | 341411029 | 1111 | +---------------------------+-----------+----------+ The record for john(a)domain.com finaly reaches the quota limit - and even removing all emails does not help. My /etc/dovecot/dovecot-dict-quota.conf looks like this: map { pattern = priv/quota/storage table = quota username_field = username value_field = bytes } map { pattern = priv/quota/messages table = quota username_field = username value_field = messages } And my question is: what is used as "username"? Always the username given wher user logs in? Is there a way to provide some dictionary to translate all aliases to the real username? Best regards, -- Jacek Osiecki joshua(a)ceti.pl GG:3828944 I don't want something I need. I want something I want.

[Dovecot] [PATCH] Indexing mail attachments with Dovecot + Solr
by Antonio Perez-Aranda 31 Aug '11

31 Aug '11

Indexing mail attachments with Dovecot + Solr. This patch has been tested with these versions: * dovecot 2.0.9 * apache-solr 1.4.1 This is a patch for the fts-solr plugin (that indexes mail messages for Dovecot with Solr). In main stream, the plugin does not index attachments; With this patch, you can index mails and their attachments (pdf, docs, openoffice docs...) . You can get others goodies with this patch and the Solr Config provided, like Synonyms and Stemming (Spanish by default). Attachment indexing is provided by Solr Cell and Tika (ExtractingRequestHandler) * http://wiki.apache.org/solr/ExtractingRequestHandler Synonyms and Stemming are provided by SnowballPorterFilterFactory from Solr Language Analysis: * http://wiki.apache.org/solr/LanguageAnalysis We have tested Solr with Tomcat and Jetty. Tomcat is better to handle UTF-8 and bigger POSTS. Attachments file format supported * http://tika.apache.org/0.9/formats.html At present, attachments in attachments (like, for example, attachments in fordwarded "eml" attachments) are not indexed. Also, keep in mind that there are many types of files, and many variants of the same file type. Per Example, some pdf files are "not readable" by solr pdf reader. Config: There are two new options added to fts_solr property: * index-attachments Enable attachments indexing. * manual-update Avoid index on user search. You can trigger indexing using doveadm search or doveadm index commands. There is a new property for the section plugin to filter the mimetypes that you want to index. * fts_solr_mimetype files with this mimetype will be sent to solr. After integrating solr directory in your solr config, and building Dovecot with fts-solr support and with fts-solr-attachments-r885.patch applied, you can update your dovecot config by adding to your dovecot.conf: ... mail_pluings = $mail_plugins fts fts_solr plugin { fts = solr fts_solr = url=http://solrhost:8983/solr/ break-imap-search index-attachments fts_solr_mimetype = application/x-pdf application/vnd.openxmlformats-officedocument.wordprocessingml.document } ... -- 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

Having enabled shared mailboxes - is there a way to provide access to all users' mailboxes by a given user? Instead of having to manually provide ACL rights to every mailbox of every user? -- Daniel

[Dovecot] possible bug leading to lmtp crashes
by Trever L. Adams 09 Jun '11

09 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.
