[Dovecot] BUG: LDAP extension failed to authenticate if 'base' DN configuration is empty ''
by Hendy Irawan 31 Jul '12

31 Jul '12

Dear Dovecot developers, We have several context entries and want to authenticate a user against the whole LDAP server. However when setting "base = " Dovecot LDAP fails with following message: Jul 29 10:50:59 nitik1 dovecot: auth: Error: ldap(hendy(a)staging.member.berbatik.com,127.0.0.1): ldap_search((virtualMail=hendy(a)staging.member.berbatik.com)) failed: Other (e.g., implementation specific) error This limits the search to only one base DN, e.g. base = dc=staging,dc=berbatik,dc=com The ldap client library is able to search entries using an empty base DN, so it should be possible for Dovecot LDAP to do the same. An even more elegant solution will be the ability to specify multiple base DNs, but if Dovecot can search the "root DN" (empty string) it would be great. Thank you.

Hi Timo, since I've upgraded to 2.1.8, solr indexer doesnt work correctly. I see a lot of these errors in logs: Fatal: master: service(indexer-worker): child 9582 returned error 83 (Out of memory (service indexer-worker { vsz_limit=256 MB }, you may need to increase it)) I've tried to set vsz_limit to a lot more, (around 4096 MB) but same problem occurs. thank for your help !

[Dovecot] mdbox with separate index location results in many emptydirectories
by Jürgen Obermann 31 Jul '12

31 Jul '12

Hallo, I use dovecot 2.1.7 with mdbox format and I specified a separate location for mailbox index files with mail_location = mdbox:/dovecot/storage%h:INDEX=/dovecot/index%h With this setting I get for every mailbox a directory under both filesystems /dovecot/index and /dovecot/storage, e.g. for the inbox it looks like that: # ls -lR /dovecot/index/home/hrz/myuser/mailboxes/INBOX /dovecot/storage/home/hrz/myuser/mailboxes/INBOX /dovecot/index/home/hrz/myuser/mailboxes/INBOX: total 49 -rw------- 1 myuser hrz 20480 Jul 20 11:12 dovecot.index.cache -rw------- 1 myuser hrz 1280 Jul 20 08:00 dovecot.index.log -rw------- 1 myuser hrz 301 Jul 19 16:45 dovecot.index.search -rw------- 1 myuser hrz 20 Jul 19 16:45 dovecot.index.search.uids /dovecot/storage/home/hrz/myuser/mailboxes/INBOX: total 3 drwx------ 2 myuser hrz 2 Jul 19 15:20 dbox-Mails /dovecot/storage/home/hrz/myuser/mailboxes/INBOX/dbox-Mails: total 0 As expected the index files now reside under /dovecot/index%h/mailboxes/, but the path /dovecot/storage%h/mailboxes/ also contains for every user and every mailbox name a directory which in turn contains only an empty subdirectory 'dbox-Mails'. These directories seem to me to sum up to a lot of unneded infrstructure objects. I tried to delete these empty directories, but dovecot did not like that and stopped to work. So somehow they are necessary, in spite of setting a separate index file location. So my question is, could these empty directories be avoided, perhaps in a future version?

I propose to improve error messages but inserting quotes. I spent good time until I looked into source code to find right meaning of error message. I would like them in following format: namespace configuration error no 'hidden=no' namespaces

[Dovecot] Empty argument in "executable = script ..." service
by Florian Wagner 31 Jul '12

31 Jul '12

Hi, what is the point of adding an empty argument to the command called by the "executable = script ..." setting in a service? I guess that would be the call to array_append_space at line 57 in util/script.c. Background is that I'm trying to run bogofilter through the extprograms Pigeonhole plugin. So I've defined a service entry with a unix_listener and wondered why my test shell script works but bogofilter exits with a cryptic error. Turns out that this empty argument at the end trips up the bogofilter argument parsing code. If I manually call bogofilter with execv and add that empty argument I get the same cryptic error. Regards Florian

[Dovecot] Dovecot Director behaviour when two or more fail
by Dominic Malolepszy 31 Jul '12

31 Jul '12

Hi, On the Dovecot wiki here http://wiki2.dovecot.org/Director it says the following: "The directors are going to connect to each others in a ring. For example if you have servers called A, B and C, director will create connections A->B, B->C and C->A" I am curious what happens in a scenario when two or more directors fail and potentially break a ring in half, do the active directors detect this and reform a new ring?

[Dovecot] Help needed with configuration giving dict error No such file
by Ajax 31 Jul '12

31 Jul '12

Each time a mail message is delivered to a mailbox records like the following appear in /var/log/dovecot.warn: Jul 29 10:02:05 iris dovecot: lmtp(29320, jax(a)XXX.com) Error: file dict commit: file_dotlock_open(/var/vmail/XXX.com/jax/home/maildir/dovecot-quota) failed: No such file or directory Jul 29 10:02:05 iris dovecot: lmtp(29320, jax(a)XXX.com) Error: file dict commit: file_dotlock_open(/var/vmail/XXX.com/jax/home/maildir/dovecot-quota) failed: No such file or directory Jul 29 10:02:05 iris dovecot: lmtp(29320, jax(a)XXX.com) Error: dict quota: Quota update failed, it's now desynced This is with Dovecot 2.1.7 installed by Debian Squeeze binary packages, dovecot-core v 1:2.1.7-2~bpo60+1, and friends. The host is running GNU/Linux 3.2.0-0.bpo.2-amd64 and on a xfs filesystem. Entries in /etc/dovecot/users look like this: jax@XXX.com:{plain}password The output from 'doveconf -n' is in the attachment to this mail message. I'm a beginner without experience with either IMAP servers or clients. Can you give me pointers to see what I'm missing that causes the errors logged as above? The user data base looks like this: userdb { args = uid=5000 gid=5000 home=/var/vmail/%d/%n/home mail=maildir:/var/vmail/%d/%n driver = static } Being a beginner, I wonder if is necessary to manually make home directories for each '/var/vmail/%d/%n/home'? I've tried test accounts with and without empty "home" directories at the indicated locations without seeing any difference in the error indications. Is it necessary to manually populate the "home" directories? Besides having no clue about the errors logged, I don't understand what it takes to make quotas work nor do I understand what options are available or advisable. The distribution wiki/QuotaMaildir.txt seems clear that the Maildif+++ backend is indicated but beyond that I remain in the dark. FWIW, I've yet to try a real IMAP client. Thank you for any pointers you can give me.

[Dovecot] Problem with running two dovecot instances on the same server
by Alexandr Sabitov 31 Jul '12

31 Jul '12

Hello All, Have anyone met the problem I am struggling with at the moment ? The problem is when I run two instances of dovecot 2.1.8 which are one for proxy-director and another one is a regular one on the same server then I have big amount of strange entries in the /var/log/mail.err: Jul 26 11:51:20 dovecot-test-1 dovecot: director: Error: Empty server list Jul 26 11:51:20 dovecot-test-1 dovecot: director: Fatal: Invalid value for director_mail_servers setting Jul 26 11:51:20 dovecot-test-1 dovecot: master: Error: service(director): command startup failed, throttling for 60 secs Jul 26 11:52:20 dovecot-test-1 dovecot: director: Error: Empty server list Jul 26 11:52:20 dovecot-test-1 dovecot: director: Fatal: Invalid value for director_mail_servers setting Jul 26 11:52:20 dovecot-test-1 dovecot: master: Error: service(director): command startup failed, throttling for 60 secs That's for sure set->director_mail_servers variable in main_preinit of ./src/director/main.c But after dumping it it turns out that ppid of the process which failed to use main_preinit function is a "regular" dovecot not the proxy one. When main_preinit is used by dovecot-proxy then set->director_mail_servers = ip address of a mail server and it is all good but if main_preinit is used by dovecot then set->director_mail_servers = empty and I get fatal errors in logs. So here is a question: How come that "non-proxy" dovecot requests director_mail_servers variable and writes fatal error in the logs if it doesn't find it ? Thank you very much for any assistance!

[Dovecot] maildir_copy_with_hardlinks on v.2.0.19
by mailing list subscriber 31 Jul '12

31 Jul '12

Hi, I'm trying to get the so-called "single instance store" (I think cyrus has got the name for the first time) with dovecot --version = 2.0.19 binary package installed from ubuntu 12.04 lts official repo. I have checked that "maildir_copy_with_hardlinks" is enabled ("dovecot -a|grep hard" shows "yes") then I have installed and enabled the lmtp component of dovecot. The configuration "dovecot -n" is pasted here: http://paste.lug.ro/131180 Also in the same paste is a strace against dovecot and childrent showing evidence of the MTA delivering a single copy of the message via LMTP with multiple RCPT TO: headers. However when looking in the Maildir, I see the mail break down into three separate files instead of expected hardlinked files ("stat" and "ls" shows one single link count, inodes are different) Given the above data, what (am I | dovecot is) doing wrong? Please cc me if you need additional input when replying as I'm not subscribed to the list (I'll watch the thread online only) Many thanks in advance.
