[Dovecot] quota-related crash for doveadm dsync operation
by Emmanuel Dreyfus 15 May '13

[Dovecot] Lucene and Zlib with 2.2.1
by Kyle Wheeler 15 May '13

15 May '13

Hello, I have an "archive" folder in my inbox, where I manually stick old mails into a compressed mbox format. Since upgrading to Dovecot 2.2.1, I've started seeing messages like the following in my log files: imap(...): Error: lucene: Failed to sync mailbox INBOX: Mailbox isn't selectable indexer-worker(...): Error: lucene: Failed to sync mailbox INBOX: Mailbox isn't selectable indexer-worker(...): Error: lucene: Failed to sync mailbox INBOX: Mailbox isn't selectable indexer-worker(...): Error: lucene: Failed to sync mailbox INBOX: Mailbox isn't selectable imap(...): Error: indexer failed to index mailbox INBOX/Archive/2007/Sent.gz These errors *appear* to be mostly benign; I still get results from searching the mailbox. But for whatever reason, the indexer appears to not be working for those folders. As you can probably tell, I'm using the fts_lucene plugin, which used to work just fine (with Dovecot 2.1.x). Is this expected behavior? Are these errors truly ignorable? Why are these compressed mailboxes not selectable? ~Kyle -- Where justice is denied, where poverty is enforced, where ignorance prevails, and where any one class is made to feel that society is an organized conspiracy to oppress, rob and degrade them, neither persons nor property will be safe. -- Frederick Douglas

by Hajo Locke 15 May '13

15 May '13

Hello, i use dovecot 2.1.7 and exported all my XLIST FolderSettings to userdb Whole Story is here: http://dovecot.org/list/dovecot/2013-March/089209.html This is all successful, but there is one problem left. I use lines like this to realize individual XLIST Foldernames in usedb: namespace/inbox/mailbox=Sent namespace/inbox/mailbox/Sent/name=Sent namespace/inbox/mailbox/Sent/auto=subscribe namespace/inbox/mailbox/Sent/special_use=\sent My problem is to allow Foldernames with whitespace in it f.e. Sent Messages I tried to put these names in quotes in this line or mask the blank with backslash but nothing was working. Dovecot ist not accepting these settings: dovecot: imap: Debug: Added userdb setting: namespace/inbox/mailbox="Sent Messages" dovecot: imap: Debug: Unknown userdb setting: plugin/namespace/inbox/mailbox/"Sent Messages"/auto=subscribe dovecot: imap: Debug: Unknown userdb setting: plugin/namespace/inbox/mailbox/"Sent Messages"/name="Sent Messages" dovecot: imap: Debug: Unknown userdb setting: plugin/namespace/inbox/mailbox/"Sent Messages"/special_use=\sent How to code folders with whitespace etc. in my userdb settings? I tried a lot but nothing was correct. Thanks, Hajo

[Dovecot] protocols and privileges
by andreas graeper 15 May '13

15 May '13

hi, 1) protocols = pop3 but when starting the service, output tells about imap. when mua fetches mails ~/mail/.imap/INDEX is created. 2) i have some users uid=500 .. 505. src in /var/mail/%u, owner is <user>.mail and home-directories /home/<user> - owner is <user>.users when dovecot tries to create directory /home/<user>/mail then it tells for user xyz (uid = 502) euid=502(xyz) egid=100(users) missing +w permission /home/xyz , euid is not dir owner. but /home/xyz is owned by xyz.users and mod = 0700 ( drwx------ ) same environment for uid = 501 works great ! thanks in advance andreas ? permission lookup from /home/xyz/mail failed do i have to create that mail directory manually ?

[Dovecot] dovecot 2.2.1: lmtp running in base_dir
by Andy R 15 May '13

15 May '13

Evening all, I'm running into an issue with lmtp trying to store user mail in 'base_dir' ( same as this ( http://www.dovecot.org/list/dovecot/2011-January/056736.html )) however I'm just using PAM for auth. I've tried with chroot, without chroot and 'chroot'ing lmtp directly in ' service lmtp { } ' which just lead to lots more errors. I've not included anything of the current config so far, as I don't know what is needed here yet. I'm sure I'm missing something obvious, but I can't spot it for the life of me. Can anyone offer any new ideas? Many thanks Andy R.

[Dovecot] Dovecot 2.2.1 subscribtion status in LIST
by Nikolay S. 15 May '13

15 May '13

Hi there, I am using Evolution to connect to dovecot imap server. Today the server was upgraded to 2.2.1 from 2.1.9, and there is problem with evolution being unable to subscribe to INBOX. This is from dovecot 2.1.9: a002 list "" "*" return (subscribed) * LIST (\Subscribed) "." "Sent Items" * LIST (\Subscribed) "." "Junk E-mail" * LIST (\Subscribed) "." "Trash" * LIST (\Subscribed) "." "Archive" * LIST (\Subscribed) "." "Drafts" * LIST (\Subscribed) "." "INBOX" <--- And this is from 2.2.1: a002 list "" "*" return (subscribed) * LIST (\Subscribed) "."

[Dovecot] IMAP SSL proxy (questions)
by Trever L. Adams 15 May '13

15 May '13

Hello everyone, I have seen: http://wiki.dovecot.org/HowTo/ImapProxy. It doesn't seem to fit what I need. Unfortunately, I cannot use TLS. I have to use SSL. Also, I would rather not duplicate the certificates for the IMAP servers. Hence nginx doesn't seem to be a good choice either. I am hoping that since SSL has "Client Hello" which specifies the site requested the the following could be done: Client - > Proxy [SYN] Proxy -> Client [SYN, ACK] Client -> Proxy [ACK] Client -> Proxy [SSL With "Client Hello", having server_name in Extension: server_name and sub-fields] Proxy sees intended host Proxy <-> Intended Server [SYN/SYN+ACK/ACK sequence] Proxy -> Intended Server [Replay SSL/Client Hello] Client <-> Proxy <-> Intended Server (Proxy is non decrypting Man-in-the-Middle, just acting as a pseudo-invisible relay) I know that something somewhat like this works because this is how Apache can do virtual hosts with SSL. Of course, it acts as the end point intended server, not a proxy. I believe it is also somewhat how Squid does SSL proxying, although I could be entirely wrong. Is this possible? Can this be implemented in dovecot? If not, does anyone know of such a project. Proxy needs to not have any exploitable holes and really only needs to understand enough SSL to get the server_name, pass through the connection, replaying Client Hello, and then knowing when to shut the connection. Just as a breif example, the use I have for this now is that I have several imap servers which all have IPv6 addresses, but have to share an IPv4 address. for SMTP side of things, this works well for all incoming email. (As an aside, does anyone know of a similar setup for SSL traffic on port 465 SSL for SMTP?) Thank you for any help, Trever

[Dovecot] Keyword limit?
by Michael M Slusarz 15 May '13

15 May '13

Running into a weird issue in a mailbox that has 26+ keywords. In one session, I do this: S: 2 SELECT "INBOX" (QRESYNC (1255685337 78608 [...uids...])) S: [...] S: * OK [HIGHESTMODSEQ 78608] Highest S: * OK [UIDVALIDITY 1255685337] UIDs valid S: 2 OK [READ-WRITE] Select completed. C: 3 UID STORE 48386 (UNCHANGEDSINCE 78608) +FLAGS AAAAAAAA S: * 8 FETCH (UID 48386 MODSEQ (78609) FLAGS (\Seen AAAAAAAA)) S: 3 OK Store completed. C: 4 LOGOUT S: * OK [CLOSED] Previous mailbox closed. S: * BYE LOGOUT received S: 4 OK Completed The next time I access that mailbox, I see this: C: 2 SELECT "INBOX" (QRESYNC (1255685337 78609 [...uids...])) S: [...] S: * OK [UIDVALIDITY 1255685337] UIDs valid S: * OK [HIGHESTMODSEQ 78609] Highest S: * 8 FETCH (MODSEQ (78610) UID 48386 FLAGS (\Seen)) S: 2 OK [READ-WRITE] Select completed. MODSEQ 78610 is entirely server-initiated. It *appears* that the mailbox doesn't handle more than 26 keywords. My dovecot-keywords looks like: 0 $Forwarded [Entries 1-24] 25 Test "Test" is a keyword I created immediately before "AAAAAAAA". If I remove Test and then add "AAAAAAAA", the keyword sticks. Is this a built-in limit? Can't find anything in the config/wiki docs (Dovecot 2.1.16). Or are my dovecot index/cache files hosed in some way? michael

[Dovecot] Mail deduplication
by Tim Groeneveld 15 May '13

15 May '13

Hi Guys, I am wondering about mail deduplication. I am looking into the possibility of seperating out all of the message bodies with multiple parts inside mail that is recived from `dovecot` and hashing them all. The idea is that by hashing all of the parts inside the email, I will be able to ensure that each part of the email will only be saved once. This means that attachments & common parts of the body will only be saved once inside the storage. How achievable would this be with the current state of dovecot? Would it even be worth doing? Thanks, Tim

[Dovecot] quota and dict
by Jeff Gustafson 15 May '13

15 May '13

I have a question about using dict and quotas. I want dovecot to send quota queries to a custom dict server over a socket. I'm doing this because I can't do group quotas based on domain since a customer can have each of their users associated with different domains under a single account. I need to lookup the account ID and group based on that. I'm worried putting everything in mysql will cause way too many writes and lower the performance of our mysql cluster. I have having a little trouble connecting all the dots in the config file. In the userdb example, there is an 'args' parameter that allows a file to specify a uri. I don't see how to do that for dict. I only see file, mysql, and postgresql. Shouldn't I be able to use a dictionary proxy to attach any custom program to a quota dict socket? Tell the quota plug to proxy quota which then points to a socket: plugin { quota = dict:User quota::proxy::quota } dict { quota = proxy:/tmp/test-socket } or should it be: plugin { quota = dict:User quota::proxy:/tmp/test-socket } Neither one create a socket in /tmp. It seems like this should be possible, but I don't see an obvious way to do it. ...Jeff

[Dovecot] Released Pigeonhole v0.4.0 for Dovecot v2.2.1.
by Stephan Bosch 15 May '13

15 May '13

Hello Dovecot users, I finally release the first version of Pigeonhole v0.4 for Dovecot v2.2. The main reason for the delay was that some unexpected (design) problems occurred with the new doveadm-sieve plugin, which allows synchronizing sieve scripts using doveadm sync. One important change is that I incorporated the extprograms plugin into the main Pigeonhole release. With this plugin it is possible to execute administrator-controlled external programs (shell scripts) from the Sieve interpreter, e.g. for special message delivery, filtering and string manipulation. The list of new features is not that impressive. I've been working on IMAP URLAUTH, IMAP CATENATE and HTTP support for Dovecot. Currently, I'm building an SMTP submission proxy server. After all that I plan to spend more time on Sieve development. One of the most important issues on my list is implementing support for using alternative types of storage (e.g. a database) for Sieve scripts, rather than only a filesystem directory as it is now. Changelog v0.4.0: + Added doveadm-sieve plugin that provides the possibility to sync Sieve scripts using doveadm sync along with the user's mailboxes. + Added the Sieve extprograms plugin to the main Pigeonhole package. It is still a plugin, but it is now included so that a separate compile is no longer necessary and distributors are likely to include it. The extprograms plugin provides Sieve language extensions that allows executing (administrator-controlled) external programs for message delivery, message filtering and string manipulation. Refer to doc/plugins/sieve_extprograms.txt for more information. + Added debug message showing Pigeonhole version at initialization. Makes it very clear that the plugin is properly loaded. + Finished implementation of the Sieve include extension. It should now fully conform to RFC 6609. The main addition is the new :optional tag which makes the include command ignore missing included scripts without an error. + Finished implementation of the Sieve environment extension as much as possible. Environment items "location", "phase" and "domain" now also return a usable value. The release is available as follows: http://www.rename-it.nl/dovecot/2.2/dovecot-2.2-pigeonhole-0.4.0.tar.gz http://www.rename-it.nl/dovecot/2.2/dovecot-2.2-pigeonhole-0.4.0.tar.gz.sig Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information. Have fun testing this new release and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

[Dovecot] 2.2.x autobuilds: Debian Stable now Wheezy, which pool for 2.2.x?
by Ron Leach 15 May '13

15 May '13

List, good evening, just installed a new Debian Stable (Wheezy). The Debian Stable repositories now include Dovecot 2.1.7 as standard. I haven't installed that because I wanted to try 2.2.x on this new clean install but unsure which 'pool' to use in the xi.rename-it.nl repository of autobuilds. http://xi.rename-it.nl/debian/pool/ Wheezy became Stable on May 5, just a few days ago. I'm not sure whether to still follow the advice in the wiki for obtaining 2.2.x for Wheezy, which (understandably, because the new Debian Stable release has been so very recent) continues to refer to Wheezy as 'testing'. http://wiki2.dovecot.org/PrebuiltBinaries#Automatically_Built_Packages Presumably, the packages in the 'testing' autobuild system pick up Debian's 'testing' pool libraries (or assume them to exist) and these may no longer be the ones needed for Wheezy because Wheezy is 'Stable', in Debian-speak. Does anyone know, for sure, which autobuild pool to now use for 2.2.x for Wheezy? http://xi.rename-it.nl/debian/pool/stable-auto/ or http://xi.rename-it.nl/debian/pool/testing-auto/ 2.2.x in 'stable-auto' doesn't seem to have changed since before Wheezy was released, whereas 2.2.x has changed in 'testing-auto', and I'm not sure what to make of that. Stephan does suggest that queries be directly written to him, but I posted here because I thought I might not be the only person who was unsure. I'd be grateful for any advice, regards, Ron

[Dovecot] Idea: POP3 deletion as a flag
by Timo Sirainen 14 May '13

14 May '13

GMail doesn't delete mails when POP3 client issues a DELE command for it. Instead they just become invisible for future POP3 sessions, but they still exist for IMAP/webmail. The same could be implemented pretty easily for Dovecot: - Add a new setting to enable this: pop3_deleted_flag = $POP3Deleted - When DELEting a message, add this flag to the message. - When listing messages, skip all messages that have this flag. - Also hide this flag from IMAP clients(?) Thoughts? Probably 20 lines of new code.

I have Doveot 2.1.1 on Centos, all's well user mails are kept for 60 days, then, 'aged off' (deleted) a Mac user with two domains and two dozen users asked me: can I set a mail server on my home Mac server, and, 'mirror' the real mail server mailboxes so than I can have an offline mail archive for ever ? I know very little about Macs, can I setup dovceot on Mac? any tips/suggestions/howtos for mirroring/archiving as so?

[Dovecot] Any way to let dovecot block pop3 attempts?
by Steve Campbell 12 May '13

12 May '13

Is there a way using dovecot facilities to block an IP from attempting POP3 connections (similar to the sendmail access file for smtp connections)? I usually do this at my border firewall, but if there's a quick and dirty way in dovecot to do this, it'd make life a little simpler. Thanks steve campbell

Re: [Dovecot] change inbox dotlock name
by Chris Saldanha 10 May '13

10 May '13

Axel Luttgens <AxelLuttgens(a)swing.be> wrote: > But I fear I don't understand your problem description. > Could you elaborate? Hi Axel, The issue is that the procmail port on FreeBSD doesn't acquire a dotlock when it's the default lock file (/var/mail/username.lock). It prints that it's bypassing the dotlock and just does a lockf() lock after. Looking in the code for procmail, it seems that it's being too clever with a bunch of checks and so it doesn't try to get the lock -- it's decided it doesn't want to before doing it. The permissions and runtime environment permit the lock, and the same lock is acquired correctly by dovecot when writing to the inbox. I'm doing dotlock and then lockf() locking in all the mail software. procmail's checks only seem to apply to the default lock file for the inbox. If I specify an alternate name in the .procmailrc for the $ORGMAIL delivery of the message, then it will acquire any other lock I ask, including an alternate name in the /var/mail directory. I'll dig into the procmail sources as needed to resolve it, but I had hoped that I could get dovecot to lock with a different filename, because that would resolve the issue with minimal hackery...

[Dovecot] dovecot not logging after upgrade to 2.1.7 on debian
by Steinar Bang 09 May '13

09 May '13

After upgrading my IMAP server to the new debian stable, and upgrading dovecot from 1.x to 2.1.7 in the process, dovecot no longer logs anything to /var/log/mail.*. The last entries there are from before the upgrade, and no starts or error messages or failed login attempts, since then, have been logged. Does anyone know what might cause this? "doveconf -n" doesn't mention any of the log settings. Maybe the log settings aren't picked up? What could be done to make sure they are picked up? Here's the content of the /etc/dovecot/conf.d/10-logging.conf file: ## ## Log destination. ## # Log file to use for error messages.

May 6 18:37:59 nordkap dovecot: lda: Error: userdb lookup: connect(/var/run/dovecot/auth-userdb) failed: Connection refused May 6 18:37:59 nordkap dovecot: lda: Fatal: Internal error occurred. Refer to server log for more information. >> For me it looks odd because the auth-userdb is defined as << base_dir = /usr/local/var/run/dovecot/ service auth { unix_listener auth-userdb { mode = 0777 user = vmail group = vmail } .... >> The rights on the file should be correct according to the config above << ls -al /usr/local/var/run/dovecot/auth-userdb srwxrwxrwx 1 vmail vmail 0 May 6 20:11 /usr/local/var/run/dovecot/auth-userdb >> I cannot explain why the lda tries to access << Error: userdb lookup: connect(/var/run/dovecot/auth-userdb) >> I grepped through all the configfiles but could not find the "wrong" path from the error message above. Would it might be a "fix" to symlink /usr/local/var/run/dovecot to /var/run/dovecot ? Or would that break something with dovecot? Thanks for any hint or idea tobi

[Dovecot] SSL problems on dovecot 2.1.7
by Steinar Bang 09 May '13

09 May '13

When I upgraded my debian-based imap server from squeeze to wheezy yesterday, SSL stopped working. I am using a http://cacert.org signed server sertificate, and I am reusing the certificates that were used on the 1.x dovecot of debian squeeze. My three MUAs that worked against the previous 1.x dovecot with the same certificate, now fails in various ways. Any hints and guesses as to how to debug this further will be highly appreciated. Even more appreciated will be a pin point of the issue. :-) Here are the error messages from the MUAs: - Opera 12.15 on Windows 7 just reports: "The connection with the IMAP server was unexpectedly interrupted." - Emacs24(w/linked-in gnutls)/Ma Gnus 0.8 (Gnus git HEAD) on Windows 7 says "imap.mydomain.com certificate could not be verified." - Emacs23/Ma Gnus 0.8 (also Gnus git HEAD) on debian testing (with Emacs23 gnutls-cli is run in a subprocess), says: "Opening connection to imap.mydomain.com via tls... Opening TLS connection to `imap.mydomain.com'... Opening TLS connection with `gnutls-cli --insecure -p 993 imap.mydomain.com'...done Opening TLS connection to `imap.mydomain.com'...done Unable to open server nnimap+privat due to: Process *nnimap* not running" When I try running gnutls-cli from the command line of the debian testing machine (the same gnutls-cli that is used by the emacs23/gnus combo), it seems to connect ok (the transcript of that session is below). The config for the SSL, from /etc/dovecot/conf.d/10-ssl.conf, is: # SSL/TLS support: yes, no, required. <doc/wiki/SSL.txt> ssl = yes # PEM encoded X.509 SSL/TLS certificate and private key. They're opened before # dropping root privileges, so keep the key file unreadable by anyone but # root. Included doc/mkcert.sh can be used to easily generate self-signed # certificate, just make sure to update the domains in dovecot-openssl.cnf ssl_cert = </etc/ssl/certs/imap_mydomain_com.pem ssl_key = </etc/ssl/private/imap_mydomain_com.key The access privileges of the files, are: -rw-r--r-- 1 root root 2077 Mar 27 12:45 /etc/ssl/certs/imap_mydomain_com.pem -rw------- 1 root root 3243 Jul 12 2011 /etc/ssl/private/imap_mydomain_com.key What follows, is the transcript from the gnutls-cli session from a debian testing machine to the server (which seems to be working as far as I can tell...): sb@edwards:~$ gnutls-cli -p 993 rainey.mydomain.com WARNING: gnome-keyring:: couldn't connect to: /home/sb/.cache/keyring-yeEdM3/pkcs11: No such file or directory Resolving 'rainey.mydomain.com'...
