Dovecot auth-ldap ignores tls_* settings when using ldaps://
by Heiko Schlittermann 13 Oct '15

13 Oct '15

Hi, I'm using dovecot 2.2.9 (but after checking src/auth/db-ldap.c in 2.2.13 there seems to be the same bug/feature). The userdb and passdb use LDAP. All further configuration is done in auth-ldap.conf.ext. uri = ldaps://<host>/ # tls = tls_cert_file = /etc/ssl/certs/client-cert.pem tls_key_file = /etc/ssl/certs/client-key.file Dovecot ignores the tls_* options. If I use an ldap:// URI and switch on TLS using tls=yes it works as expected. But I do not see any reason why LDAPS should not read the tls_* settings. This small patch solved it for me --- dovecot-2.2.9/src/auth/db-ldap.c 2013-11-24 14:37:39.000000000 +0100 +++ dovecot-2.2.9.hs12/src/auth/db-ldap.c 2015-10-08 21:24:47.051446465 +0200 @@ -1043,7 +1043,7 @@ static void db_ldap_set_tls_options(struct ldap_connection *conn) { - if (!conn->set.tls) + if (!(conn->set.tls || strncmp(conn->set.uris, "ldaps:", 6) == 0)) return; #ifdef OPENLDAP_TLS_OPTIONS It would be great, if somebody can confirm this and if this or some equivalent patch could make it upstream.

Multiple core solr support
by Daniel Miller 13 Oct '15

13 Oct '15

Is it possible to use variables, such as domain or username, in the plugin url declaration? This would allow using multiple cores to separate the stored indexes. So when my own giant mailbox gets corrupt...I don't have to rebuild everybody's... Something like url=http://mysolr.server.com:8983/solr/%u -- Daniel

fts solr ignores new mailboxes until fts rescan
by Giorgio Paolucci 13 Oct '15

13 Oct '15

Hello, on my debian wheezy installation, I implemented fts plugin with solr as indexing system. I noticed that if a user creates a new folder, that folder it is ignored by dovecot indexing until a doveadm fts rescan is performed for that user. From that time on everything works ok on that folder. As a test I set fts_autoindex=yes and put in that folder a brand new mail never indexed before. in my logs indexer-worker says it indexed 0 messages Obviously this is a major issue as users often create new folders, but a search always returns empty results. My system is a debian wheezy with dovecot packages from backports dovecot 2.2.13-11~bpo70+1. Am I missing something? Any clue would be appreciated. Thank you all in advance.

Hello, i have installed Centos 7.1.1503 with Dovecot 2.2.10-4.el7_0.1. With Thunderbird all works fine, but when i configure the email client of Mac (Yosemite) with IMAP i can see a error in the log and the client not see the emails: Oct 9 14:31:34 localhost dovecot: imap(xxxxxxx@xxxxxxx): Fatal: master: service(imap): child 18639 killed with signal 11 (core dumps disabled) I have read the instructions of http://www.dovecot.org/bugreport.html, but core file is not writing.

iterate users with passwd-file passdb?
by Eric Abrahamsen 12 Oct '15

12 Oct '15

Apologies for the basic question, but I've been googling and can't figure out if this is possible or not. Simply: Is it possible to iterate over users if I'm using the passwd-file passdb driver? Do I need a SQL-based driver if I want to iterate? Here's what I've got right now. I don't have many users, and would prefer to retain the simplicity of the passwd-file if possible. Thanks! passdb { driver = passwd-file args = username_format=%u scheme=ssha512 /etc/dovecot/passwd.db deny = no master = no pass = no skip = never result_failure = continue result_internalfail = continue result_success = return-ok } userdb { driver = static args = uid=5000 gid=5000 home=/var/mail/vmail/%d/%n }

Syncronizing two IMAP servers
by Timothy Murphy 10 Oct '15

10 Oct '15

I spend time in two places, in different countries. I have a local network in each place, with IMAP servers on each network. I collect email by fetchmail from various servers, and read email on my laptop with KMail. I tried using just one IMAP server, but this proved impractical. So I have two collections of the same sub-folders, on the two servers. I have two questions: 1. Is there a simpler way of organizing my email? 2. Given the current method, is there a way of syncronizing folders on the two servers? -- Timothy Murphy gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin

Maildir: ACLs/Unix perms and unable to see content of specific mailbox
by Olaf Marzocchi 10 Oct '15

10 Oct '15

Dear Dovecot users, hello. I will merge two issues I have into a single email because they may be related. I used dovecot on a OmniOS server since 2014 (currently OmniOS r151014) with the following configuration (it shows 2.2.18 because I recently updated dovecot, skipping only the PostgreSQL plugin): # 2.2.18: /etc/dovecot/dovecot.conf # OS: SunOS 5.11 i86pc zfs mail_location = maildir:/tank/home/%u/Maildir mail_privileged_group = mail namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { driver = pam } protocols = imap ssl = required ssl_cert = </etc/dovecot/certs/dovecot.pem ssl_key = </etc/dovecot/private/dovecot.pem userdb { driver = passwd } You can see that I set the Maildir folder inside the shared home folders of my server (it is only one user, anyway). It always worked perfectly, but one-two months ago I changed the permissions of my whole home folder, recursively, to add proper ACLs. I needed them because the clients started using illumos kernel SMB (relying on ACLs) instead of Netatalk/AFP (relying on Unix perms only). I didn't realise I applied the ACLs also to the Maildir folder. Dovecot worked for several weeks fine, I noticed the issue only yesterday when a mailbox (see below) appeared in Thunderbird completely empty even if the "cur" subfolder on the server still contains all the mails. Dovecot was throwing some errors like: dovecot: [ID 583609 mail.error] imap(olaf): Error: rename(/tank/home/olaf/Maildir/.&A6k- Mailing Lists.Log/dovecot.index.cache) failed: Permission denied (euid=501(olaf) egid=501(olaf) UNIX perms appear ok (ACL/MAC wrong?)) dovecot: [ID 583609 mail.error] imap(olaf): Error: rename(/tank/home/olaf/Maildir/.&A6k- Mailing Lists.Log/dovecot.index.tmp, /tank/home/olaf/Maildir/.&A6k- Mailing Lists.Log/dovecot.index) failed: Permission denied dovecot: [ID 583609 mail.error] imap(olaf): Error: unlink(/tank/home/olaf/Maildir/subscriptions.lock) failed: Permission denied dovecot: [ID 583609 mail.error] imap(olaf): Error: rename(/tank/home/olaf/Maildir/subscriptions.lock, /tank/home/olaf/Maildir/subscriptions) failed: Permission denied I will post here the current permissions of the folder containing Maildir, of the Maildir itself, of its contents, and of the folder that appears empty when browsed with a client (Thunderbird). /tank/home/olaf $ ls -lV .. drwx------+ 16 olaf olaf 17 Sep 19 01:52 olaf user:olaf:rwxpdDaARWcCos:fd-----:allow group:2147483648:rwxpdDaARWcCos:fd-----:allow everyone@:rwxpdDaARWcCos:fd-----:deny /tank/home/olaf $ ls -lV drwxrwx--- 348 olaf olaf 359 Sep 19 01:51 Maildir owner@:rwxp--aARWcCos:-------:allow group@:rwxp--a-R-c--s:-------:allow everyone@:------a-R-c--s:-------:allow /tank/home/olaf $ ls -lV Maildir/ drwxrwx--- 2 olaf olaf 2 Jan 30 2014 cur owner@:rwxp--aARWcCos:-------:allow group@:rwxp--a-R-c--s:-------:allow everyone@:------a-R-c--s:-------:allow -rwxrwx--- 1 olaf olaf 21 Jan 30 2014 dovecot-keywords owner@:rwxp--aARWcCos:-------:allow group@:rwxp--a-R-c--s:-------:allow everyone@:------a-R-c--s:-------:allow (ALL THE SAME PERMISSIONS FOR THE OTHER FILES EXCEPT...) -rwxrwx--- 1 olaf olaf 13735 Jan 24 2015 subscriptions owner@:rwxp--aARWcCos:-------:allow group@:rwxp--a-R-c--s:-------:allow everyone@:------a-R-c--s:-------:allow -rw-rw---- 1 olaf olaf 13709 Sep 19 01:51 subscriptions.lock owner@:rw-p--aARWcCos:-------:allow group@:rw-p--a-R-c--s:-------:allow everyone@:------a-R-c--s:-------:allow The folder that appears empty: /tank/home/olaf $ ls -lV Maildir/.Generiche/ total 513 drwxrwx--- 2 olaf olaf 949 Sep 18 01:42 cur owner@:rwxp--aARWcCos:-------:allow group@:rwxp--a-R-c--s:-------:allow everyone@:------a-R-c--s:-------:allow -rwxrwx--- 1 olaf olaf 46 May 18 2014 dovecot-keywords owner@:rwxp--aARWcCos:-------:allow group@:rwxp--a-R-c--s:-------:allow everyone@:------a-R-c--s:-------:allow (ALL THE SAME PERMISSIONS FOR THE OTHER FILES) I really hope you will have the time to help me because I already applied the permissions recursively and I removed the ACLs, almost as it was before my mistake. I specified "almost" because originally (I checked the backups) the Maildir folder had an ACL that gave access permissions also to the group "mail": drwxrwx---+349 olaf olaf 359 Feb 16 2014 Maildir group:mail:rwxpdDaARWcCos:fd-----:allow owner@:rwxpdDaARWcCos:fd----I:allow group@:rwxpdDaARWcCos:fd----I:allow everyone@:rwxpdDaARWcCos:fd----I:deny Yesterday I haven't replicated it because from the documentation I understood it was not necessary. My questions, in short: - what are the permissions I need to give to the Maildir folder? I understood from the documentation it's 700, with my user/group (the one of the user accessing the mail). What about ACLs? and what about group "mail"? - the (only!) subfolder which appears empty in Thunderbird, may it depend on the permissions? maybe due to them the index was not updated and UIDs don't match. If after applying the correct permissions I still cannot see its contents, is there a way to recover the mails? the files are all still there. Sorry for the long email, but after several tries yesterday I exhausted my ideas. Regards, Olaf

Double Dots
by Ken Mandelberg 09 Oct '15

09 Oct '15

I've noticed lately that Dovecot seems to be inserting an extra dot in some url's contained in html email. The most consistent example I see is in the newsletters from the Washington Post. For example, if I look at the raw email on the mail server I see text that starts <http://link.washingtonpost.com/click But if I look at what Thunderbird shows it starts http://link..washingtonpost.com/click/ I don't think its Thunderbird adding the dot, since K9 mail on my Android phone shows the same issue. It's only after the IMAP delivery that the extra dot appears. We are running dovecot 2.0.12 Incidentally, the newsletter is full of these link.washington post url's. For each article it appears 3 times, once on title, once on a "read full article" link, and one on a picture. Its only the one on title, that gets the extra dot after its been through dovecot. Furthermore, it only happens from the second article on. Any ideas?

Dovecot plugin and Push Mail
by Steffan Cline 08 Oct '15

08 Oct '15

I’m posting this here and will in a couple other places to see if anyone has any experience with this and knows what I can do. My setup is CentOS 6 with postfix, procmail and dovecot administered via Virtualmin. Postfix of course receives the email. Procmail uses it’s hooks to run the email through spam assassin and clamd. After than procmail hands it off to dovecot/deliver to drop it in the user’s mail box. I use the following plugin for dovecot with the daemon to provide Apple push mail for iPhones. https://github.com/st3fan/dovecot-xaps-daemon https://github.com/st3fan/dovecot-xaps-plugin For the most part, this works awesome but have run into a bit of a race issue with notification of mail in a particular instance. On my computer I use Outlook for Mac which says it supports IDLE but is broken. When an email comes in, I ALWAYS get the notification via the dovecpt plugin for a push since Outlook is checking IMAP every 2 minutes. On a buddy’s setup, he uses Apple Mail which supports IDLE that actually works. When his email client is connected from his laptop, it does actually maintain a persistent connection and NEVER receives a notification from the dovecot plugin because I’m guessing dovecot/deliver sees that the email was received by the desktop client. I’m not sure how to make the plugin ALWAYS give a push. Is it a dovecot config? A bug in the plugin? I’m not sure. Suggestions? Thank you, Steffan Cline 602-793-0014

how to treat synonymous domain names as one
by Nikolai Krot 08 Oct '15

08 Oct '15

Hallo List Users, I am curious if there is a way to rewrite domain name to another domain name. My goal is to provide authentication and mailboxes for the synonymous domains in a single source while keeping all other domains separate. I have setup: auth_username_format = %Lu mail_location = /var/vmail/%d/%u/Maildir in userdb/passdb (passwd-file): /etc/dovecot/%d/users Say I have two synonymous domain names my-domain-1.com my-long-named-domain-1.com I want both to resolve to my-domain-1.com when %d variable is used in Dovecot configs, so that passwd-file is /etc/dovecot/my-domain-1.com/users mailbox is /var/vmail/my-domain-1.com/user/Maildir while keeping other domains unchanged my-other-domain-2.com should resolve to: passwd-file is /etc/dovecot/my-other-domain-2.com/users mailbox is /var/vmail/my-other-domain-2.com/user/Maildir thanks, Nikolai
