[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) "." "Sent Items" * LIST (\Subscribed) "." "Junk E-mail" * LIST (\Subscribed) "." Trash * LIST (\Subscribed) "." Archive * LIST (\Subscribed) "." Drafts * LIST () "."

INBOX is actually subscribed: cat <path-to-maildir>/subscriptions Drafts Sent Items Archive Trash INBOX Junk E-mail

[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 14 May '13

14 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 14 May '13

14 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... Cheers, Chris -- Chris Saldanha Parliant Corporation

[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. "syslog" logs to syslog, # /dev/stderr logs to stderr. log_path = syslog # Log file to use for informational messages. Defaults to log_path. #info_log_path = # Log file to use for debug messages.

[Dovecot] Permission problem with LDA and dovecot 2.2.1

Hello list today I built dovecot 2.2.1 from sources. But I have permission problems with LDA The "normal" imap part works fine, users can login and see their boxes. deliver is called as LDA from postfix master.cf as follows << dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/local/libexec/dovecot/deliver -f ${sender} -d ${user}@${nexthop} >> but when I try to send a testmail then I get the following in the logs << 2013 May 6 18:37:59 nordkap lda: Fatal: Internal error occurred.

[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 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.

[Dovecot] dovecot stats
by Jan-Frode Myklebust 09 May '13

09 May '13

I just upgraded one of our servers to dovecot v2.1.16 (ee), and am looking into the stats feature. Am I interpreting the wiki correct in reading that the "doveadm stats dump command" only returns statistics about IMAP commands? Is it possible to collect info about POP3 and LMTP commands also ? Also, is "doveadm stats dump command" telling me the results of all commands that has finished the last stats_command_min_time, or will it maybe contain much more than 1 minute of activity ? -jf

[Dovecot] AuthenticationFailedException: [IN-USE] Couldn't open INBOX: Permission denied
by Earles, Jill 09 May '13

09 May '13

I've been pouring over the documentation for dovecot, but can't find a solution to this problem. I recently took over administration of the dovecot email service at the University where I work, and things were going smoothly. We've been creating email accounts for use with JIRA, a bug reporting/tracking system, and one day recently, when I tried to add a new account to JIRA, I got this error returned from dovecot: "AuthenticationFailedException: [IN-USE] Couldn't open INBOX: Permission denied" I got help from Atlassian, the creators of JIRA, and they sent me links to some forum posts that said that changing the permissions of that user's /var/mail/ directory to 0600 would solve the problem. I changed that and no longer got the error. Being satisfied that this was a solution, I created a bunch of new email accounts today to replace exchange accounts, and then changed the permissions on all the /var/mail/ directories to 0600. Now I'm getting that error again, even for pre-existing email addresses, including the one that I had previously fixed by changing the permissions the same way. I tried changing some of the older accounts back to 0660, which is what they had before, and I still get the error even after restarting dovecot. JIRA uses POP, port 110, to connect to the dovecot mail server. I've also had the same problem trying to connect from Mac Mail. Our JIRA application is used for tracking issues for the UBC Libraries, and those email addresses are critical for the creation of tickets and adding comments to tickets. I am at a loss for what to do. Can anyone help? Thank you very much for your time. # dovecot -n # 2.0.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-131.0.15.el6.x86_64 x86_64 Red Hat Enterprise Linux Server release 6.4 (Santiago) auth_debug = yes auth_debug_passwords = yes disable_plaintext_auth = no mail_access_groups = mail mail_location = mbox:~/mail:INBOX=/var/spool/mail/%u mail_privileged_group = mail mbox_write_locks = fcntl passdb { driver = pam } ssl_cert = </etc/pki/dovecot/certs/server.crt ssl_key = </etc/pki/dovecot/private/server.key userdb { driver = passwd } protocol pop3 { pop3_uidl_format = %08Xu%08Xv } Here's an except of the maillog from a recent attempt: May 8 17:46:49 moose dovecot: auth: Debug: pam(lib.sysadmin,{ip removed}): lookup service=dovecot May 8 17:46:49 moose dovecot: auth: Debug: pam(lib.sysadmin,{ip removed}): #1/1 style=1 msg=Password: May 8 17:46:49 moose dovecot: auth: Debug: client out: OK#0111#011user=lib.sysadmin May 8 17:46:49 moose dovecot: auth: Debug: master in: REQUEST#0111028653057#01128298#0111#011a60ed90501af39d7e353a14e027255cd May 8 17:46:49 moose dovecot: auth: Debug: passwd(lib.sysadmin,{ip removed}): lookup May 8 17:46:49 moose dovecot: auth: Debug: master out: USER#0111028653057#011lib.sysadmin#011system_groups_user=lib.sysadmin#011uid=523#011gid=524#011home=/home/lib.sysadmin May 8 17:46:49 moose dovecot: pop3-login: Login: user=<lib.sysadmin>, method=PLAIN, rip={ip removed}, lip={ip removed}, mpid=28302 May 8 17:46:49 moose dovecot: pop3(lib.sysadmin): Error: stat(/var/spool/mail/lib.sysadmin) failed: Permission denied May 8 17:46:49 moose dovecot: pop3(lib.sysadmin): Error: stat(/var/spool/mail/lib.sysadmin) failed: Permission denied May 8 17:46:49 moose dovecot: pop3(lib.sysadmin): Error: Couldn't open INBOX: Permission denied May 8 17:46:49 moose dovecot: pop3(lib.sysadmin): Couldn't open INBOX top=0/0, retr=0/0, del=0/0, size=0 May 8 17:46:50 moose dovecot: auth: Debug: auth client connected (pid=28303) May 8 17:46:50 moose dovecot: auth: Debug: client in: AUTH#0111#011PLAIN#011service=pop3#011lip={ip removed}#011rip={ip removed}#011lport=110#011rport=64420#011resp=AGJ2YXV3LnJlbGFpcwByM2xAaXMuYnZAdXc=

[Dovecot] change inbox dotlock name
by Chris Saldanha 08 May '13

08 May '13

Hi, Is there a configuration element that would allow me to change the dot-lock name for the user's /var/mail inbox when it is locked? dovecot (correctly) acquires <username>.lock, but I'm having a problem with procmail where some obscure code path is preventing procmail's acquisition of a lock when it's that default name in /var/mail. The issue is not permissions (using a world-writeable and sticky-bit config for /var/mail). I'll dig into the procmail code if needed, but if dovecot could use a different filename for such locks, then that would solve my issue. procmail has such an option, and I only need to do this for inboxes. Thanks, Chris -- Chris Saldanha Parliant Corporation

[Dovecot] sieve redirect envelope address problem
by Костырев Александр Алексеевич 08 May '13

08 May '13

Good day! I have a problem with mail redirection through sieve rules. I've configured sieve rule that redirects any mail coming to user to gmail mailbox (or whatever external mail system there is). But when sieve redirects any mail it puts vmail@%dovecot_hostname% into envelope address, gives it to my exim for delivery and gmail rejects my mail because user vmail@%dovecot_hostname% do not exist. Please, advice for what can be done about this behavior. my `doveconf -n` http://pastebin.com/0dyL9Jgs Thanks in advance! -- С уважением, Костырев Александр администратор Linux-систем

[Dovecot] CATENATE mis-reads literal after bad URL
by Mike Abbott 08 May '13

08 May '13

Dovecot-2.2.1 plus Timo's recent CATENATE and URLAUTH fixes mishandles literals after bad URLs. (As before remember that the "foobar" text below is really "foobarCRLF" hence the length of 8. Also, last time some MTA discarded an important single leading space character in the snippet I quoted so this time I'm prefixing all the lines to avoid that. In case it's lost again, there's a space before the word "url" below.) | b append inbox catenate (text {8} | + OK | foobar | url /a-bad-url text {8} | b NO [BADURL /a-bad-url] Invalid messagepart IMAP URL. | c noop | d noop | d OK NOOP completed. | e logout | * BYE Logging out | e OK Logout completed. Note that the command with tag "c" is lost. I think it shouldn't be, because the NO was reported to the client without sending a continuation (+ OK) so the client knows not to send the literal. Plus it appears only one line is discarded regardless of the size of the literal.

Auch beim Debug-Logging sind leider nicht mehr Infos zum Fehler zu finden. Zum Einsatz kommt aktuell Postfix 2.10.0 und Dovecot 2.2.1. Die Dovecot Quota Konfiguration sieht so aus, wie bei sys4 beschrieben: service quota-status { executable = quota-status -p postfix unix_listener /var/spool/postfix/private/quota-status { group = postfix mode = 0660 user = postfix } client_limit = 1 } Mittlerweile habe ich schon einige Optionen und Berechtigungen ausprobiert, aber der Fehler bleibt leider der gleiche. Hat vielleicht jemand noch einen Tip? Danke schon mal. -- Daniel

[Dovecot] imap crash during URLFETCH
by Mike Abbott 06 May '13

06 May '13

Dovecot-2.2.1's imap processes crash reliably when they use an IMAP URL with an invalid access specifier. A backtrace and some debug output follows. The crash is likely caused by imap_urlauth_fetch_parsed() returning 0 without having set *mpurl_r to NULL, and then imap_urlauth_fetch_local() freeing an uninitialized pointer.

[Dovecot] doveadm search causes replication error message
by Oli Schacher 06 May '13

06 May '13

Hi # 2.2.1 (83d83f55e5c2+) / dsync replicated setup I just noticed that 'doveadm search' apparently tries to replicate mailboxes and spits out errors if a mailbox in the search query is not found: #doveadm search -u user(a)example.com mailbox Spamreport doveadm(user(a)example.com): Error: Syncing mailbox Spamreport failed: Mailbox doesn't exist: Spamreport this is especially problematic with -A searches as this causes a error message for every user which doesn't have that folder. Is this a bug or intended behaviour? Should I just 2>/dev/null these errors in doveadm scripts? Thanks Oli -- message transmitted on 100% recycled electrons

[Dovecot] SELECT/EXAMINE don't report URLMECH
by Mike Abbott 06 May '13

06 May '13

In dovecot-2.2.1 neither the SELECT nor the EXAMINE commands include an untagged URLMECH reply. (Note, this is not the one mandated by the RESETKEY command.) AFAICT RFC 4467 does not require an URLMECH reply to SELECT or EXAMINE but without it clients have no way of knowing about authorization mechanisms other than INTERNAL. Now I know dovecot-2.2 supports only the INTERNAL mechanism at present so this is probably harmless, but still I think it's worthwhile to ask: Is the absence of the URLMECH reply intentional or an oversight? For comparison Apple's enhanced dovecot replies: c1 select inbox [...] * OK [URLMECH INTERNAL] Mechanisms supported c1 OK [READ-WRITE] Select completed.

[Dovecot] many SSH connexions with dsynx/SSH replication
by Emmanuel Dreyfus 06 May '13

06 May '13

Hi I am trying replication over dsync/ssh, as explained there: http://wiki2.dovecot.org/Replication I added the options below to dovecot.conf. It works, but it seems there is a new SSH connexion for each user, which is a bit overkill performance-wise. Since I sync as root, I guess there is a way of haing everything on the same SSH connexion? --- cut here --- mail_plugins = $mail_plugins notify replication service replicator { process_min_avail = 1 } dsync_remote_cmd = ssh -lroot %{host} doveadm dsync-server -u%u plugin { mail_replica = remote:root@mail1.example.net } service aggregator { fifo_listener replication-notify-fifo { user = dovecot } unix_listener replication-notify { user = dovecot } } service replicator { unix_listener replicator-doveadm { mode = 0600 } } service doveadm { inet_listener { port = 12345 ssl = yes } } doveadm_port = 12345 ssl_client_ca_file = /etc/openssl/certs/ca.crt doveadm_proxy_port = 0 --- cut here --- -- Emmanuel Dreyfus manu(a)netbsd.org

[Dovecot] dsyncing lazy_expunge namespace
by Angel L. Mateo 06 May '13

06 May '13

Hello, I'm in the process of migrating mailbox from one dovecot server running dovecot 2.1.9 with mailboxes stored in maildir format to a newer one running 2.1.16 with mailboxes stored in mdbox format. To migrate mailboxes I'm using dsync as explained at http://wiki2.dovecot.org/Tools/Dsync. The command I'm running in the newer server is: sudo dsync -o mailbox_list_index=no mirror -R -u <user> imapc: The mailbox of the user is correctly synced to the newer server, except the lazy_expunge namespace, which is not synced at all. The config in my old server is: namespace { # hidden = yes # list = no # Temporally, only for migration hidden = no list = yes location = maildir:~/Maildir/expunged prefix = BORRADOS. separator = . } and in the newer one is: namespace { hidden = yes list = no location = mdbox:%h/expunged:INDEX=/mail/indexes/%2Ln/%Ln/expunged prefix = BORRADOS/ separator = / } With a tcpdump I have checked that old servers list the namefolder, this is the IMAP dialog for an example user: * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE AUTH=PLAIN] Dovecot ready. 2 AUTHENTICATE PLAIN YW5nZWwubHVpcwBtYXN0ZXIAVkFzR293ZW0= 2 OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS THREAD=ORDEREDSUBJECT MULTIAPPEND UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS SPECIAL-USE QUOTA ACL RIGHTS=texk] Logged in 1 LIST "" "" * LIST (\Noselect) "."

[Dovecot] XFS vs EXT4 for mail storage
by Charles Marcus 05 May '13

05 May '13

Hello, I'm in the process of finalizing the spec for my new dovecot VM, and this is the last question I need to address... I've read until I'm just about decided on XFS, but I have no experience with it (been using reiserfs on my old box (@ 8 yrs old now), and never had a problem (knock on wood), but considering its current situation (little to no development support for reasons everyone is aware of), I've decided now is the time to switch. It came down to XFS or EXT4, and I like what I've read about XFS, but am unsure how to tune it (or even if I should). I've decided to use mdbox for storage (been using maildir), and will enable SIS for attachments. So, anyone (Stan?) have any suggestions? Should I go with EXT4? Or XFS with just the defaults? Or XFS with one or more tuned parameters? Appreciate any suggestions (including links to docs dealing with tuning XFS for my mail storage conditions that are written more at the layman level) or comments from anyone experienced using both... Thanks, -- Best regards, Charles

[Dovecot] Dovecot has no understandable configuration any more
by forum 04 May '13

04 May '13

Hello, for many years i used an mailserver with dovecot V1 very satisfied! http://mailserver.decotrain.de/ One of the reasons to use dovecot was a simply configuration. Dovecot was the best choice for IMAP for me! Now i updated the server to Debian testing with dovecot 2.1.7. It's not possible for me to get a running authentication for virtual mail users! I recently found this mailing and have the same problem: http://www.dovecot.org/list/dovecot/2012-March/064181.html The documentation says *nothing* about my problem how to authenticate with mysql! http://wiki2.dovecot.org/VirtualUsers I can solve the problem only with try and error without a chance in this complex system. It's nice to have all this possibilites but they are not useful if not documented. There should be some clear examples for different scenarios to be found in your wiki. My problem at this time: I don't know how to configure the userdb to work with mysql authentification? All mail is running under the special user mail. dovecot.conf ============ disable_plaintext_auth = yes passdb { driver = sql # Path for SQL configuration file, see example-config/dovecot-sql.conf.ext args = /etc/dovecot/dovecot-sql.conf } userdb { driver = prefetch } first_valid_uid = 8 last_valid_uid = 8 first_valid_gid = 8 last_valid_gid = 8 mail_location = maildir:/srv/mail/%d/%n dovecot-sql.conf ================ driver = mysql connect = host=/var/run/mysqld/mysqld.sock dbname=... => WORKS! default_pass_scheme = SHA1 password_query = SELECT password, '/srv/mail/%d/%n' AS home, 'mail' AS uid, 'mail' AS gid FROM user WHERE username = '%n' AND domain = '%d' AND IMAP_allowed = 'YES' Errors ====== Apr 30 10:28:22 auth: Debug: client out: OK 1 user=xxxx@yyyy home=/srv/mail/yyyy/xxxx uid=mail gid=mail Apr 30 10:28:22 auth: Debug: master in: REQUEST 3163291649 5347 1 87066c907eef8f4e5ed71319b560dd2a Apr 30 10:28:22 auth: Error: prefetch(xxxx@yyyy,::1,<doTKyI/brgAAAAAAAAAAAAAAAAAAAAAB>): userdb lookup not possible with only userdb prefetch Apr 30 10:28:22 auth: Error: userdb(xxxx@yyyy,::1,<doTKyI/brgAAAAAAAAAAAAAAAAAAAAAB>): user not found from userdb prefetch Apr 30 10:28:22 auth: Debug: master out: NOTFOUND 3163291649 Apr 30 10:28:22 imap: Error: Authenticated user not found from userdb, auth lookup id=3163291649 (client-pid=5347 client-id=1) Apr 30 10:28:22 imap-login: Info: Internal login failure (pid=5347 id=1) (internal failure, 1 succesful auths): user=<karsten(a)dct.mine.nu>, method=PLAIN, rip=::1, lip=::1, mpid=5352, secured, session=<doTKyI/brgAAAAAAAAAAAAAAAAAAAAAB> I have no idea how to solve the problem and up to know i could not find an example with google.

[Dovecot] Accessing mail files not owned by imap login user
by PaulM47 03 May '13

03 May '13

Hi, I have managed to set up a 'maildir' based mail system using fetchmail and procmail that delivers sorted mail to folders /var/spool/mail/user1, ../user2 etc. 'user1', 'user2' etc. are real users but the mail system is run under logged in user 'mailserver'. The mail folders are owned by 'user1', 'user2' etc. but mail files, when delivered, are owned by 'mailserver'. I've been unable to find a way to change this behaviour :-( Dovecot is configured by adding the single line 'mail_location = maildir:/var/spool/mail/%u' to 'dovecot.conf', everything else is as installed. When I make an imap connection as 'user1' the logon is successful, the mail files are moved from ../new/ to ../cur/ but are invisible to the imap client. If I 'chown' the mail files to 'user1' they instantly become visible to the imap client. I gather from googling info on dovecot I can configure dovecot to allow 'user1', when logged in, to access the mail files owned by 'mailserver'. Is this simple to do, and if so how do I do it please ? Thanks PaulM -- View this message in context: http://dovecot.2317879.n4.nabble.com/Accessing-mail-files-not-owned-by-imap… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] feature request: pipe for custom quota dict queries
by Jeff Gustafson 03 May '13

03 May '13

Just a followup to my previous post. I appears that a pipe for quota queries via dict is not supported right now. Because of the way we group things we need more flexibility. I'd like to propose that dovecot should support quota queries just like userdb dict queries. My expertise is not C, but I might try to poke around and see if I can make something work. ...Jeff

[Dovecot] sieve: deleteheader sometimes fails [bug]
by Daniel Piddock 03 May '13

03 May '13

Hi, We're using Dovecot 2.1.16 with Pigeonhole 0.3.4. Mail is delivered by exim4 to the dovecot LDA. Sometimes users are unable to delete headers. I've narrowed the problem down to preceding the deleteheader command with a query against the body. A simple example: """ require ["body", "editheader", "fileinto"]; if body :contains "!TEST!" { fileinto "INBOX.Trash"; stop; } deleteheader "Subject"; addheader "Subject" "Testing"; """ Putting the "deleteheader" above the "if body" causes it to be deleted correctly. Although I've used Subject in this example it happens for other headers. Cheers, Dan

[Dovecot] CATENATE allows zero parts
by Mike Abbott 03 May '13

03 May '13

I'm pleased to see that dovecot-2.2 includes support for RFCs 4467 and 4469 (URLAUTH and CATENATE). I have begun testing these features (in dovecot-2.2.1) and comparing their functionality against Apple's implementation. So far I have discovered a few inconsistencies. I will report each of these, and any more that I may find, in separate threads. The first issue is that using CATENATE with no message parts works but, IMO, shouldn't: a2 append inbox catenate () a2 OK [APPENDUID 1366726248 9] Append completed. For comparison this is how Apple's enhanced dovecot in OS X Server handles this request: a2 append inbox catenate () a2 BAD Invalid arguments. According to RFC 4469 section 3 CATENATE requires "one or more message parts." This is formalized in section 5: append-data =/ "CATENATE" SP "(" cat-part *(SP cat-part) ")" and in RFC 3501 section 9 which states that "[ABNF] rules MUST be followed strictly." I believe that permitting zero cat-parts is contrary to the RFC, although I can understand permitting it under the general doctrine of "servers should be liberal in what they accept, and clients strict in what they send." Is accepting zero cat-parts an intentional exception to the RFC or an oversight?

[Dovecot] CATENATE doesn't support literal+ url
by Mike Abbott 03 May '13

03 May '13

Dovecot-2.2.1 does not appear to support URLs specified via non-synchronizing literals (RFC 2088 LITERAL+), and also does not read and discard the literal+ input after reporting the error. This results in the literal+ input being interpreted as IMAP commands, which could alter the user's mail store in unexpected ways and/or lead to the abrupt disconnection of the client for exceeding the maximum number of bad IMAP commands. Example using dovecot-2.2.1 (note that the text nonsync literal includes the invisible CRLFs: "foobarCRLFbarbazCRLF"): a3 append inbox catenate (url {9+} /some-url text {16+} foobar barbaz ) a4 noop a3 BAD Error in IMAP command APPEND: Invalid arguments. foobar BAD Error in IMAP command : Unknown command. barbaz BAD Error in IMAP command : Unknown command. ) BAD Error in IMAP command : Unknown command. a4 OK NOOP completed. Example using Apple's enhanced dovecot in OS X Server: a3 append inbox catenate (url {9+} /some-url text {16+} foobar barbaz ) a4 noop a3 NO [BADURL /some-url] missing or invalid uid a4 OK NOOP completed. I believe the RFCs indicate that nonsync literal URLs should be permitted. RFC 4469 section 5: append-data =/ "CATENATE" SP "(" cat-part *(SP cat-part) ")" cat-part = text-literal / url url = "URL" SP astring RFC 3501 section 9: astring = 1*ASTRING-CHAR / string string = quoted / literal RFC 2088 section 4: literal ::= "{" number ["+"] "}" CRLF *CHAR8

[Dovecot] Tuning!
by Rafael VOlpe TI 02 May '13

02 May '13

Hi Buddies, I have 2 servers running dovecot + postfix for pop/imap users. The users mailbox are in a Nfs storage. The load of server is ranging at 3.0 to 15.0. I really dont know what happened.. I read a lot about tuning of dovecot, and the changes are applied, how you can see. The Hardware of server is really good! The host have 8GB of mem and 2 sockets with 2 cores anyone. The server receives 900-1000 user connections in pop and imap. How i can aprimmorate this processes? Some errors are displayed on the console randomly when the load rises. Example: May 02 13:57:42 pop3(user(a)domain.com): Error: Timeout (180s) while waiting for lock for transaction log file //var/vmail/ domain.com/user//dovecot.index.log May 02 13:57:42 pop3(user(a)domain.com): Error: Couldn't init INBOX: Internal error occurred.

[Dovecot] Dovecot vs MBox
by Gregory Sloop 02 May '13

02 May '13

I'm still in the "what's wrong" stage of figuring out what's going on. But I've got a mail user who isn't getting new messages. Postfix accepts it and drops it in the users mbox. [This is verified. If I tail the Mbox, I can see the new messages.] "Mail" will see the messages too. But dovecot doesn't seem to know they exist. I don't think the MBox is corrupt, as I've tossed the first few messages in hopes that it would then read the rest, but no luck. Any ideas where to look next, what I might do to force dovecot to forget message ID's etc - that might force it to read the whole mailbox file again? [Or a pointer as to where it might be most productive to poke next?] TIA -Greg -- Gregory Sloop, Principal: Sloop Network & Computer Consulting 503.251.0452 x121 Voice | 503.251.0452 Fax www.sloop.net mailto:gregs@sloop.net

[Dovecot] CATENATE allows empty messages
by Mike Abbott 02 May '13

02 May '13

Dovecot-2.2.1 allows empty messages to be APPENDed when using CATENATE: b1 append inbox catenate (text {0+} ) b1 OK [APPENDUID 1366726248 12] Append completed. Contrast this with regular APPEND: b2 append inbox {0+} b2 NO Can't save a zero byte message. Note that zero-size literals are OK but zero-size messages are not. So while "b1" above should fail like "b2", this should continue to succeed: b3 append inbox catenate (text {0+} text {8+} foobar ) b3 OK [APPENDUID 1366726248 13] Append completed.

[Dovecot] Slow DNS warnings (proxy/auth)
by Christian Balzer 02 May '13

02 May '13

Hello, I've just finished transiting our proxies from perdition to dovecot (2.1.7-7 Debian). Yesterday 12 messages (all within the same second) like this caught my attention: --- Apr 25 17:19:09 pp11 dovecot: auth: Warning: proxy(redacted(a)gol.com,xx.xx.xx.xx,<26hUEivbfQBlMrMS>): DNS lookup for mb04.dentaku.gol.com took 5.002 s --- Now this machine at that time was handling a load of about 2 logins per second, about 20% of what it previously handled with perdition w/o a hiccup. It also runs a local caching nameserver and the A record for the mailbox server in question was most definitely cached at the time (verified via TTL). The machine in question was very bored and certainly capable of handling hundreds if not thousands of DNS queries per second at that moment. In short, I can't see any reason how the lookup could have taken so long, so my guess is there are some issues with the dns-helper (locking, stepping on each others feet, not being spawned fast enough) causing this. Some general remarks, dovecot as proxy feels "heavier" than perdition. In the CPU area that's probably a more subjective impression, because all the little helper processes make it clear what's going on where. Though the "config" process being rather active is something that perdition definitely doesn't do, it reads the config once at start time and that's it. All the IPC and central processes of course also make dovecot rather file handle hungry. Memory wise it's about 35% bigger than perdition and that's not subjective at all. ^o^ About one MB per proxy process/connection for dovecot in my case. Caveat emptor. ^o^ Regards, Christian -- Christian Balzer Network/Systems Engineer chibi(a)gol.com Global OnLine Japan/Fusion Communications http://www.gol.com/

[Dovecot] Dovecot has no understandable configuration any more
by forum 30 Apr '13

30 Apr '13

Hello, my last problem could be solved now with userdb { driver = static args = uid=mail gid=mail home=/srv/mail/%d/%n } I can connect to dovecot locally with an webmailer. But there is no listener process to be seen outside of the server? Locally this ports are working, but not outside: # netstat -tulpn | grep dove tcp6 0 0 :::110 :::* LISTEN 5741/dovecot tcp6 0 0 :::143 :::* LISTEN 5741/dovecot tcp6 0 0 :::993 :::* LISTEN 5741/dovecot tcp6 0 0 :::995 :::* LISTEN 5741/dovecot Is this a configuration problem inside dovecot? Another problem is the migration from the existant emails from V1 to V2: In the log i can find: Apr 30 11:14:57 imap(xxxx@yyyy): Error: Broken file /srv/mail/yyyy/xxxx/.INBOX.dir.09/dovecot-uidlist line 1: Broken header (uidvalidity = 0, next_uid=697) How can i recover this? Delete all the index files? Has someone an idea how to migrate the emails from charset ISO8859-1 to UTF-8? Best regards Karsten

[Dovecot] last login timestamp

Hello, I am settiing up a dovecot (imap, pop, sieve, lda) + openldap infrastructure. I need to store the timestamp of the last login of each user in an attribute of its corresponding ldap object. I could not find a way of doing this through configuration options so I am thinking of coding this task into the dovecot-auth source code, maybe in the passdb-ldap.c file. What do you recomend about this? Thanks. __________ Information from ESET Mail Security, version of virus signature database 8278 (20130429) __________ The message was checked by ESET Mail Security. http://www.eset.com

[Dovecot] mailbox_list_index_parse_header crash
by Kyle Wheeler 29 Apr '13

29 Apr '13

Hi, I got all excited about IMAP NOTIFY support and tried enabling mailbox_list_index on my server. Unfortunately, I rather quickly ran into trouble of the segfault variety. This prevented me from doing basic things like seeing the contents of some of my folders. Disabling mailbox_list_index got me back up and running, but... darnit, that's annoying. The only message I got in my log file was this: imap(user@domain): Fatal: master: service(imap): child 6899 killed with signal 11 (core dumped) If I can help track this down, please let me know.

[Dovecot] Dovecot 2.1.16 doveadm purge -A segfault

[Dovecot] Dovecot Solr Panic
by Andre Rodier 29 Apr '13

29 Apr '13

Hello Everyone, I have a small base of users (30), but a lot of emails. I have an error again when I am indexing a virtual folder with a large number of folders. I appreciate this is a special case, but I am using dovecot and solr as it is, according to the documentation, the favourite way. One user is using a large number of archives sub folders, by years, months and subfolders, since 5 years. I am convincing this user to give up this organisation, but in the mean time, I hope to solve this problem. The virtual folder, called Archives, references all the sub folders in the Archive folder. There is about 380 folders, and worst of all, 55k characters with their names concatenated. On solr, I have increased the value of headerBufferSize to a huge value, but I have still this error. Anyway, this is the error I have when I try to index this virtual folder: ---8<--------------------------------------------------------------------------------------------------------------------------------------- root@lapetus:/mnt/emails/indiefield.co.uk/jsmith/Mails/Virtual# doveadm -v index -u 'john smith' 'Search/Archives' doveadm(john smith): Info: Search/Archives: Caching mails seq=109580..127362 1800/17783doveadm(john smith): Panic: file solr-connection.c: line 416 (solr_connection_select): assertion failed: (!conn->posting) doveadm(john smith): Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(+0x4414a) [0x7fcb7b5b014a] -> /usr/lib/dovecot/libdovecot.so.0(default_fatal_handler+0x2a) [0x7fcb7b5b020a] -> /usr/lib/dovecot/libdovecot.so.0(i_fatal+0) [0x7fcb7b58782a] -> /usr/lib/dovecot/modules/lib21_fts_solr_plugin.so(+0x754a) [0x7fcb790fa54a] -> /usr/lib/dovecot/modules/lib21_fts_solr_plugin.so(+0x4037) [0x7fcb790f7037] -> /usr/lib/dovecot/modules/lib20_fts_plugin.so(fts_backend_get_last_uid+0x5a) [0x7fcb79b2f66a] -> /usr/lib/dovecot/modules/lib20_fts_plugin.so(+0xc1fd) [0x7fcb79b341fd] -> /usr/lib/dovecot/modules/lib20_fts_plugin.so(+0xc689) [0x7fcb79b34689] -> /usr/lib/dovecot/modules/lib20_fts_plugin.so(+0xc51e) [0x7fcb79b3451e] -> doveadm(+0x16719) [0x7fcb7bf71719] -> doveadm(+0x13346) [0x7fcb7bf6e346] -> doveadm(+0x13e21) [0x7fcb7bf6ee21] -> doveadm(doveadm_mail_try_run+0x161) [0x7fcb7bf6f2e1] -> doveadm(main+0x3d1) [0x7fcb7bf6def1] -> /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xfd) [0x7fcb7b200ead] -> doveadm(+0x13125) [0x7fcb7bf6e125] Aborted ---8<--------------------------------------------------------------------------------------------------------------------------------------- On the solr side: ---8<--------------------------------------------------------------------------------------------------------------------------------------- 28-Apr-2013 17:13:33 org.apache.solr.update.processor.LogUpdateProcessor finish INFO: {add=[1/70af772eafc17c51fb350000812a8a77/john smith(a)indiefield.co.uk, 2/70af772eafc17c51fb350000812a8a77/john smith(a)indiefield.co.uk, 3/70af772eafc17c51fb350000812a8a 77/john smith(a)indiefield.co.uk, 4/70af772eafc17c51fb350000812a8a77/john smith(a)indiefield.co.uk, 5/70af772eafc17c51fb350000812a8a77/john smith(a)indiefield.co.uk, 6/70af772ea fc17c51fb350000812a8a77/john smith(a)indiefield.co.uk, 7/70af772eafc17c51fb350000812a8a77/john smith(a)indiefield.co.uk, 8/70af772eafc17c51fb350000812a8a77/john smith@indiefie ld.co.uk, ...

[Dovecot] dovecot-sql.conf - Unknown setting: driver
by jeep＠rahul.net 27 Apr '13

27 Apr '13

Im upgrading my dovecot from 2.1.14 to dovecot 2.2.1 on linux. Im using the same configuration file against my MySQL db and getting the following error: doveconf -n # 2.2.1: /opt/dovecot221/etc/dovecot/dovecot.conf doveconf: Fatal: Error in configuration file /opt/dovecot221/etc/dovecot/conf.d/dovecot-sql.conf line 2: Unknown setting: driver dovecot-sql.conf: # The mysqld.sock socket may be in different locations in different systems driver = mysql # Use "host= ... pass=foo#bar" if your password has '#' character connect = host=/var/run/mysqld/mysqld.sock dbname=mydb user=username password=pass password_query = SELECT userid AS username, domain, password \ FROM users WHERE userid = '%n' AND domain = '%d' user_query = SELECT home, uid, gid FROM users WHERE userid = '%n' AND domain = '%d' home=/opt/ii/%1n/%n/INBOX # For using doveadm -A: iterate_query = SELECT userid AS username, domain FROM users That file worked fine in the last version. Looking at the docs 'driver' is still a valid setting. Can someone help me figure out why its complaining? Ive even Im lost as to why this error is occuring unless the error itself is actually another problem and the wrong error is popping up. Been working on this for a day and cant figure it out. Thanks in advance! /mf/home/jeep/shell/.signature

[Dovecot] Replication fails with "Remote dsync doesn't use compatible protocol"
by Rich Wales 27 Apr '13

27 Apr '13

I can't get replication to work in Dovecot 2.2.1. I'm getting the following error on the machine where I'm initiating the replication: richatwork dovecot: doveadm: Error: dsync-remote(richatwork): Error: dsync(local): Remote dsync doesn't use compatible protocol Both the local and remote servers are running identical versions of Dovecot (2.2.1), so I don't understand why I would be having any sort of "compatible protocol" problem. Any ideas? I posted the "dovecot -n" output for both servers in my earlier e-mail on this issue, which I sent about 24 hours ago (and which I assume was too long for people to be willing to read).

[Dovecot] ios clients and namespace trouble
by Kelsey Cummings 26 Apr '13

26 Apr '13

We migrated to dovecot from courier and maintained a courier compatible namespace configuration. This resulted in ios clients needing to be manually configured in order to use the special folders correctly (delete messages, save drafts, etc) either by being given the correct "Path Prefix" or by manually selecting the special folders. I can't fathom why apple has chosen not to support or can't detect namespace correctly and require manual configuration but if they haven't done it by now they must have some reason for it and aren't going to fix it any time soon. Are there any creative solutions to fixing the i-clients and preventing them from needing manual configuration? -K

[Dovecot] Replication -- multiple users, three or more servers?
by Rich Wales 24 Apr '13

24 Apr '13

I'm running Dovecot 2.2.1 on an Ubuntu 12.04.2 server, with half a dozen accounts for various family members. I want to set up replication involving at least three Ubuntu servers, with different users replicated on different sets of servers. For example, I might have mail for "user1" replicated on "server1", "server2", and "server3"... while mail for "user2" would be on "server1" and "server2"... and mail for "user3" would be on "server1" and "server3". I've read the wiki page (http://wiki2.dovecot.org/Replication) but I'm still confused. I'd love to see an example that clearly shows how to set up specific individual mail users to be replicated on a different set of servers for each user, like what I described above.

[Dovecot] login crashes - maybe too many simultan connections
by Frank Leonhardt 24 Apr '13

24 Apr '13

Hallo, since a few days, users sometimes have problems connecting to our mailserver, in the mail.err are many lines like this: Apr 23 11:14:25 psy2 dovecot: dovecot: child 17607 (login) killed with signal 11 (core dumps disabled) (ip=xx.xx.146.84) Users who are already logged in keep connected, but new connections are not possible.This happens only between 10 am and 3 pm, never in the early morning or at night, so i assume, maybe this is caused by too many simultaneous connections? After restarting dovecot the problem is temporary solved, new users may connect, but after one or a few days, this may happen again. # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-amd64 x86_64 Debian 6.0.1 log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login mail_privileged_group: alle mail_location: maildir:~/Maildir fsync_disable: yes mbox_write_locks: fcntl dotlock mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 auth default: passdb: driver: pam args: dovecot userdb: driver: passwd May anybody help?

(dovecot 2.1.16) I try to retrieve information about a specific user but dovecot says it doesn't exist (whereas I just created it). The following command fails: $ sudo -u vmail doveadm user pouet(a)domain.tld userdb lookup: user pouet(a)domain.tld doesn't exist If I try a more global lookup, the user is properly found: $ sudo -u vmail doveadm user *(a)domain.tld user1(a)domain.tld *pouet(a)domain.tld* Sending a query for another user works well. For example : $ sudo -u vmail doveadm user user1(a)domain.tld userdb: user1(a)domain.tld home : /var/vmail/domain.tld/user1 uid : 500 gid : 500 quota_rule: *:bytes=100M I really don't understand what's happening... The only difference I see between the users is that user1 was created when I was using dovecot 1.2... Thanks for your help.

[Dovecot] Feature request: Configure CONFIG_MODULE_DIR and AUTH_MODULE_DIR at runtime
by Rickard Nilsson 23 Apr '13

23 Apr '13

Hi! I am running dovecot 2.1.16 on NixOS (http://nixos.org) and I have been fighting the dynamically loaded dovecot modules/plugins a bit. The problem is that in Nix/NixOS all packages are completely isolated from each other (each package has a separate /lib, /libexec, /bin etc, with only its own files in it). So dovecot has all its modules under /nix/store/xxx-dovecot/{lib,libexec}/dovecot, and the Pigeonhole modules are under /nix/store/yyy-pidgeonhole/{lib,libexec}/dovecot. Now, dovecot wants to load modules only from one directory, so I created a "virtual" package that unifies all modules in /nix/store/zzz-dovecot-plugins/{lib,libexec}/dovecot. I can then use this directory as the "mail_plugin_dir" setting in dovecot.conf. This works fine, dovecot can then find the "sieve" mail plugin. The problem is the service and auth modules, that dovecot tries to load from the compile-time set MODULE_DIR/{settings,auth}. This is a problem for me, because I can't set the module path during compilation since that introduces a circular dependency between the dovecot package and the virtual dovecot-plugins package. I have solved this by hacking dovecot to read an environment variable, DOVECOT_CONFIG_MODULE_DIR, in the config_parse_load_modules function. This way I can inject my module path during runtime. But this only works for the master process, not the config process which seems to reset its environment (I assume it does this when dropping privileges). So I did another hack which lets me pass an argument to the config process which contains the module path. I can then set this argument in dovecot.conf by "service config { executable = config /my/module/path }". These hacks work, and I can now use both the sieve mail plugin and the sieve service. I have attached the patch, but this is not a request to add it to the source. My hack is a hack because I don't know enough about the inner workings of dovecot to solve it in a good way. Rather, I'm asking for some way to configure the module path in dovecot, either as an argument to the master process or as a setting in dovecot.conf. A bonus would be the ability to specify several paths that dovecot would search, then I can do away with my virtual module package. Best regards, Rickard Nilsson

I understand that the +x workaround suggested for the auth-userdb socket (so as to have 0777 permissions instead of 0666) relies on provisions made in Dovecot's code in order to relax some requirements. But I still need help for a correct interpretation... The socket receives 0666 permissions by default; any process should thus be able to read from/write to that socket. So, why set such a default, since it is anyway going to yield un-intuitive results? And, as far as the log messages are concerned: "client doesn't have lookup permissions...". Who's the client here? Still from the log: "client doesn't have lookup permissions for this user:". Which user? "userdb reply doesn't contain uid" The userdb query seems to have failed; but does it mean that is should explicitly return a uid?

[Dovecot] Dovecot 2.1.16: "default_client_count" written to the logs
by Axel Luttgens 23 Apr '13

23 Apr '13

Hello, As to be expected with low system limits, a warning may be written to the logs: master: Warning: fd limit (ulimit -n) is lower than required under max. load (256 < 1000), because of default_client_count Shouldn't it read "default_client_limit" instead of "default_client_count"? It seems that the warning is written only when reloading Dovecot, not upon Dovecot's startup. Is this deliberate? Thanks, Axel

[Dovecot] Integrate mbox into mdbox
by lutz.niederer＠gmx.net 23 Apr '13

23 Apr '13

Hi! I have several mbox files (unstructured, only the big plain mbox files) and I would like to integrate/read these mbox files into mdbox subfolders of specific users. This is a production system and I don't want to disturb running services and I am a bit afraid of not using the right command and maybe destroying (or whatever) their mailboxes. I am sure it is pretty easy. Can someone please tell me the correct dsync command line that I should use to read each mbox file (one-way) into the specific folder of the mdbox folder structure of a specific user? Thanks a lot, -lutzn

[Dovecot] Using dsync to export mail to remote IMAP account
by Joseph Tam 23 Apr '13

23 Apr '13

I've read the web/man pages on dsync, but it's not clear to me whether dsync can be used to export (rather than import) a user's mailbox to a remote non-dovecot IMAP account. (The intention is to use it whenever a user leaves and wants to copy their local mail to Google or whatever. I currently use uw-imapd's mailutil -- it works, but it's dreadfully slow.) As a first crack at it, I tried (on the dovecot server) dsync -o imapc_user=remoteuser -o imapc_password=remotepassword -o imapc_host=remote-imap-server -o imapc_port=993 -o imapc_ssl=imaps -o imapc_features=rfc822.size -o imapc_list_prefix=remoteprefix -o mailbox_list_index=no backup -f -u localuser imapc: I got this error: dsync(localuser): Error: user localuser: Initialization failed: Namespace '': Unknown mail storage driver imapc dsync(localuser): Fatal: User init failed Is exporting mail to a remote (non-dovecot) IMAP account even doable with dsync, or am I completely off-track?

[Dovecot] Dovecot Failover
by Nikolaos Milas 22 Apr '13

22 Apr '13

Hello, Assuming we have two (low traffic) servers (on different data centers) replicated using dsync, what is the best way to automatically direct users to the main server when it is up and to the redundant one when the main server is down? Using DNS? I've seen that DNS-based failover has generally issues (for example: http://serverfault.com/questions/60553/why-is-dns-failover-not-recommended, which is informative although it refers to web servers). What is the suggested approach? HAProxy? Heartbeat/Pacemaker? Any advice will be appreciated. Thanks and regards, Nick

[Dovecot] Sieve - BCC
by iliusha 21 Apr '13

Hi ! Can you help me please with sieve plugin for dovecot I have this rule: /require ["variables", "envelope", "fileinto", "subaddress", "imap4flags"]; if anyof ( address :is [ "to", "cc", "bcc" ] "test(a)example.com", envelope :contains "to" "test(a)example.com" ) { fileinto "Test"; stop; }/ and if somebody sends me an email with "test(a)example.com" in "TO" or "CC" - then sieve works properly and put this email in Test folder, but i can't understand why if it sends e-mail to "test(a)example.com" in BCC - sieve don't move it to Test but leave it in Inbox? If i run sieve-test -faD .dovecot.sieve "Message-ID" i get: /Performed actions: * store message in folder: Test Implicit keep: (none) sieve-test(root): Info: final result: success/ but in dovecot log i get: /Info: sieve: msgid=<20130421074437.570EA2BA1C1F(a)mail.com>: stored mail into mailbox 'INBOX'/ and email is going to Inbox folder, instead Test. Please tell me what i am doing wrong and how i can make sieve to work properly with BCC.

[Dovecot] listen directive changed?
by Nick Edwards 20 Apr '13

20 Apr '13

Timo, Is the global listen directive supposed to be a governing directive, like in apache? or is it there just in case you dont use it in protocols? I set a specific ipv6 address in global listen, but use [::] in proto Testing to a secondary IP, not in the global listen, it still connects, so can I ask has the original use of global listen been deprecated? ciao

[Dovecot] Moving mail servers, moving mailboxes
by Gregory Sloop 19 Apr '13

19 Apr '13

So, I've done some searching - but search terms are hard to come by, that work, for this query. In short, migrating a RHEL 5.9 server running the back-ported Dovecot 1.0.7 To: Ububtu 12.04 with 2.0.19, I believe. [I'm not against compiling a more recent version if there's some real advantage to doing so. But I'd certainly prefer to stay with the packaged version.] Most users are POP3, with some leaving messages on the server for a while. Other users are IMAP - whole mail repository on server. --- In an ideal world, I'd like to simply copy all the mailboxes/dirs from one server to the other. [Local/LAN file copies are possible] It would be great if the message ID's wouldn't change, so the read/unread/new etc status all all the messages wouldn't change between the two servers for POP/IMAP. --- So, does anyone have a reasonable walk-through for doing so? Is this a poor idea? Should I simply set myself on fire now and save everyone a lot of hassle? :) Would you suggest an alternative, and tell me if it might achieve the objectives above? I'm more than glad to take pointers to threads on this topic. I just haven't been able to dredge this up with my Google-foo. TIA -Greg

Sorry List, I am reposting with dovecot -n ------------------------------------------------------------------ Hi, all I've recently upgraded to 2.1.16 and found my self in deep .... There are 4 accounts in my setup that need to be accessed simultaneously by 5-6 PCs on a local lan. The thing is if a user A updates, deletes, flags mail messages in the imap folders the changes don't get propagated to the other mail clients. To state this clearly, PC (A) thunderbird has an account SALES, Maildir etc PC (B) thunderbird also has the SALES account. Changes from PC (A) and vice-versa like marks,deletes, or moves mails around will randomly get propagated to PC (B) Sometimes they do sometimes they don't. This never occured with previous version 1.2.xx I am attaching my doveconf -a output ..

[Dovecot] Problem with "convert" Plugin
by Andreas Schnederle-Wagner - Futureweb.at 18 Apr '13

18 Apr '13

Hello, I got a Problem with the "convert" Plugin. Trying to convert from mbox to maildir Format. OS: CentOS release 5.8 (Final) dovecot -version: 1.0.7 (Centos RPM) convert Plugin call: convert_mail = mbox:/opt/pop3/%u:INBOX=/var/spool/mail/%u When converting to maildir - POP3 works fine (except the lost UIDL - so every server-saved message is double downloaded - but did not find any fix for this problem with convert plugin) But the IMAP In-Boxes give me some headache . All Folders are converted correct - and displayed in Mail Client. But all Mails in the IMAP INBOX are "lost" (at least Mail Client won't show them anymore) Newly delivered Mails to the Inbox work - but all older ones are missing. When looking into this Folder: /var/maildata/USER/Maildir/cur/ I can see that newly delivered mails look like this: 1366122898.14776_0.SERVERNAME:2, And the old - converted ones like this: 1366119758.P14442Q12M682874.SERVERNAME:2, Can someone point me in the right direction why the converted Mails are missing? (It worked on other Servers - about 1 year ago - without any problem?!)

[Dovecot] qmail-ldap LDA Delivery and sieve
by Ruda Porto Filgueiras 18 Apr '13

18 Apr '13

Hi, I'm using dovecot 2.1.7 on debian Squeeze with ldap integration. Almost everything is working fine and I would link to thank all developers for this amazing piece of software. But after changing my qmail-ldap to do LDA integration get all the benefits from LDA and sieve, some emails return with failure like this: <sar(a)mondialline.com.br>: lda(sar): Fatal: Unknown argument: sar Usage: dovecot-lda [-c <config file>] [-a <address>] [-d <username>] [-p <path>] [-f <envelope sender>] [-m <mailbox>] [-e] [-k] It happens on messanges that could not be delivered and need to be returned to the sender. I'm using the configuration described on wiki to do qmail-ldap integration: http://wiki.dovecot.org/HowTo/qmailldap The relevant delivery command is: | /usr/lib/dovecot/dovecot-lda -a $RECIPIENT -f $SENDER -d $USER I also tried to use this way, as documented here: http://wiki2.dovecot.org/LDA/Qmail | /var/qmail/bin/preline -f /usr/lib/dovecot/dovecot-lda But in that case, some sieve plugins can't detect the mail recipient, like vacation plugin. Finally, the vacation plugin also is not doing email forwarding when I use the first delivery option above. Follow my settings: # LDAP scope = subtree user_attrs = uidNumber=11184,gidNumber=2110 user_filter = (&(objectClass=qmailUser)(uid=%u)(accountStatus=active)) pass_attrs=uid=user,userPassword=password,mailHost=host,=proxy_maybe=y pass_filter = (&(objectClass=qmailUser)(uid=%u)(accountStatus=active)) iterate_attrs = uid=user iterate_filter = (&(objectClass=qmailUser)(accountStatus=active)) # dovecot -n output: # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-xen-amd64 x86_64 Debian 6.0.7 ext4 default_client_limit = 8000 default_process_limit = 2048 disable_plaintext_auth = no hostname = mail.mondialline.com.br lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes lda_original_recipient_header = X-Original-To mail_gid = vmail mail_location = maildir:/dados/vmail/%u/Maildir mail_plugins = zlib mail_privileged_group = vmail mail_uid = vmail managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave vacation-seconds 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 = INBOX. separator = . type = private } passdb { args = /etc/dovecot/master-users driver = passwd-file master = yes pass = yes } passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { sieve = /dados/vmail/%u/.dovecot.sieve sieve_dir = ~/sieve sieve_extensions = +vacation +vacation-seconds sieve_global_dir = /var/lib/dovecot/sieve/global/ sieve_vacation_default_period = 1h sieve_vacation_max_period = 30d sieve_vacation_min_period = 0 } postmaster_address = ti(a)mondialline.com.br protocols = " imap lmtp sieve" service dict { unix_listener dict { group = vmail mode = 0600 user = vmail } } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 ssl = yes } process_min_avail = 10 } service imap { process_limit = 2048 } service managesieve-login { inet_listener sieve { port = 4190 } } shutdown_clients = no ssl_cert = </var/qmail/control/cert.pem ssl_key = </var/qmail/control/cert.pem submission_host = mail.mondialline.com.br:25 userdb { args = /etc/dovecot/dovecot-ldap.conf.ext default_fields = uid=vmail gid=vmail home=/dados/vmail/%u driver = ldap } protocol lmtp { auth_socket_path = director-userdb } protocol lda { mail_plugins = zlib sieve } protocol imap { mail_max_userip_connections = 500 mail_plugins = zlib imap_zlib } protocol sieve { mail_max_userip_connections = 100 managesieve_max_line_length = 65536 } Best regards, -- Rudá Porto Filgueiras http://python-blog.blogspot.com http://twitter.com/rudaporto

[Dovecot] Multiple Logins on same accounts from different stations
by HL 18 Apr '13

18 Apr '13

Hi, all I've recently upgraded to 2.1.16 and found my self in deep .... There are 4 accounts in my setup that need to be accessed simultaneously by 5-6 PCs on a local lan. The thing is if a user A updates, deletes, flags mail messages in the imap folders the changes don't get propagated to the other mail clients. To state this clearly, PC (A) thunderbird has an account SALES, Maildir etc PC (B) thunderbird also has the SALES account. Changes from PC (A) and vice-versa like marks,deletes, or moves mails around will randomly get propagated to PC (B) Sometimes they do sometimes they don't. This never occured with previous version 1.2.xx I am attaching my doveconf -a output .. Please Help, Thanks in advance Harry

[Dovecot] Pros and cons of having folders under INBOX vs. not
by Rich Wales 18 Apr '13

18 Apr '13

I have some questions about whether I should set up folders under INBOX vs. having them outside the INBOX namespace. I'm setting up a new Dovecot 2.2.0 on an Ubuntu 12.04.2 server. My plan is to move my users (family members) to this new server from an old Cyrus server. Everybody is currently using (and will continue to use) IMAP, and either Thunderbird or SquirrelMail as their e-mail client. I'm using the maildir mailbox format on this new Dovecot server. No one is using the new Dovecot server yet, so I'm still free to do additional tweaking of the server configuration. When I used imapsync to copy everyone's mail to the new server, I found that all the folders (other than INBOX) were renamed. On the old Cyrus server, all the folders are subfolders of INBOX, but the folders on the new Dovecot server are not. (For example, a folder named "INBOX.Dovecot" on the old server was renamed to "Dovecot" on the new server by the imapsync utility.) Can I just keep things this way on the new server? Or are my users going to run into problems if folders are not all under INBOX? I do realize that IMAP servers can be set up either to put everything under INBOX, or not, but I'm not familiar with all the pros/cons. And if I do need (or want) to put all the folders under INBOX, can I simply rename the existing folders in each user's Maildir (and also edit folder names accordingly in everyone's "subscriptions" file)? Or will Dovecot be broken unless I recopy everything from scratch (with a command-line option to imapsync to put everything in the INBOX destination namespace)? Rich Wales richw(a)richw.org

[Dovecot] auth: passwd file (info): unknown user
by Jim Knuth 17 Apr '13

Hello, the problem is: The users are system users (by Confixx) say webxpy. But behind it e-mail puts of course address like info(a)domain.de and so on. Everything functions perfectly, nevertheless, is following in the log. … … dovecot: auth: passwd file (jk): unknown user … dovecot: auth: passwd file (jim.knuth): unknown user … dovecot: auth: passwd file (info): unknown user … and so on It is tried obviously, before the domain part in the passwd file to find user info … However, there is in it only webxpy. How can I solve this dilemma, by which does this come then? auth_username_format = %n Thanks in advance as attached mine dovecot-n -- Mit freundlichen Grüßen, with kind regards, Jim Knuth

[Dovecot] Dovecot 2.2 & LEMONADE extensions
by Jan Phillip Greimann 17 Apr '13

17 Apr '13

Hi there, I read an article about dovecot 2.2, which includes the LEMONADE extensions, and was fascinated about the feature "Forward without download". We have a small internet-uplink in our office and our CEO loves to receive mails with large attachments, he also reply/forward it, so every time the full attachments get downloaded and uploaded again. Now the question is: Is LEMONADE supported by desktop-mailclients like thunderbird or just mobile Clients? (Google said nothing to this, maybe searched the wrong words) I hope someone can help me with this. Greetings, Jan

[Dovecot] Maildirs location migration
by Thomas Hummel 17 Apr '13

17 Apr '13

Hello Timo, I'm using dovecot-2.1.15 with Maildir mailboxes located on an NFS filer. Postfix is used to deliver mail through procmail ("mailbox_command) as LDA. Our team has bought another filer and everything is meant to go on it, so we're planning to migrate those mailboxes to the new filer. To test it only on a subset of users, I ended up to the following solution : 1. keep new messages in postfix mailqueue for those users (via a service and a transport) 2. prevent new dovecot authentication for those users (via the "auth-deny" passwd-file type passdb) 3. doveadm kick those users 4. copy or rsync the mailboxes 5. symlink maildir, control and indexes directories to the new filer (nfs mounted on the mail server) 6. re-enable mail delivery and imap authentication I was wondering if such a migration could be done differently in order to be seamless to the user : - for the postfix part, it would be easy, I guess, to create a new service (and a new transport map using this service) to deliver to the new location - but for the imap part, I'm not sure if it can be done. My guess is that, if feasible, it would involve some namespace settings and a dsync copy but I cannot figure out how exactly. What do you think ?

[Dovecot] process_limit must be 1
by FABIO FERRARI 17 Apr '13

17 Apr '13

Hello, recently I have migrated a dovecot configuration from a Red Hat 5 to a CentOS 6. Since the versions of dovecot are quite the same (dovecot-2.0.1-1_118.el5 vs dovecot-2.0.9-5.el6.x86_64), I was thinking that copying the configurations file from one server to the other was a good thing, but instead, when I try to start the service, I have this bad error: Avvio di Dovecot Imap: doveconf: Fatal: Error in configuration file /etc/dovecot/dovecot.conf: service(anvil): process_limit must be 1 Does anyone know why I am getting this? Is there a change in configurations between the 2 versions, is it a known issue or I have to check something else? thanks in advance Fabio Ferrari

[Dovecot] %{session} does not work with deliver_log_format
by Daniel Parthey 17 Apr '13

17 Apr '13

Hi, # 2.1.10: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-45-server x86_64 Ubuntu 10.04.4 LTS deliver_log_format = mailbox: deliver: session=<%{session}> msgid=%m from=%f: %$ produces log messages always containing "session=<session}>", like this one: Feb 24 09:22:09 10.129.3.233 dovecot: lmtp(3484, user(a)example.org) mbnWK6/NKVGcDQAAiWCYmA: sieve: mailbox: deliver: session=<session}> msgid=<20130224082208.8A807C0CF(a)mx01.example.org> from=postmaster(a)example.org: stored mail into mailbox 'INBOX/postmaster' http://wiki2.dovecot.org/Variables leads me to the assumption that %{session} works "everywhere" and for deliver_log_format too. Is deliver_log_format variable expansion handled differently from login_log_format_elements and mail_log_prefix? Regards Daniel -- https://plus.google.com/103021802792276734820

[Dovecot] Delete_to_Trash plugin and quota problem
by BINOTTO Luis SIDOR 16 Apr '13

16 Apr '13

Hello list... I am new at dovecot and I have a problem with it; any help will be very grateful We have a exchange server with outlook at the client side, and we are migrating the exchange server to postfix/dovecot(1.2.15) solution. I enabled the "deleted-to-trash" plugin (v0.3) to move the messages to the Trash folder automatically when it is deleted. Also, I am using quota and quota_imap plugins to maintain the quota for users. The quota rule for Trash folder is unlimit. The problem is, when the client reach their maximum quota and try to delete a mail in the inbox to release space. The delete to trash plugin effectively copy it to the Trash folder, but the original mail still remain (marked for delete) at the inbox folder and the quota does not released.

[Dovecot] Sync errors trying to sync old mbox inboxes to dovecot

We are currently running dovecot 2.2.rc3. I am trying to 'dsync mirror' old Qpopper/mbox inboxes to our new Dovecot/mdbox servers. For most of the several thousand accounts, it works without issue. But there are a handful of accounts that are generating the following errors. dsync(joe): Error: Sync failed for mbox file /var/opt/migrate/users/joe/inbox: seq=981 uid=981 uid_broken=0 originally needed 9 bytes, now needs 11 bytes dsync(john): Error: Sync failed for mbox file /var/opt/migrate/users/john/inbox: seq=115028 uid=115028 uid_broken=0 originally needed 34 bytes, now needs 35 bytes dsync(john): Error: Sync failed for mbox file /var/opt/migrate/users/john/inbox: seq=114779 uid=114779 uid_broken=0 originally needed 34 bytes, now needs 35 bytes dsync(john): Error: Sync failed for mbox file /var/opt/migrate/users/john/inbox: seq=114778 uid=114778 uid_broken=0 originally needed 34 bytes, now needs 35 bytes dsync(john): Error: Sync failed for mbox file /var/opt/migrate/users/john/inbox: seq=114621 uid=114621 uid_broken=0 originally needed 34 bytes, now needs 35 bytes dsync(john): Error: Sync failed for mbox file /var/opt/migrate/users/john/inbox: seq=114610 uid=114610 uid_broken=0 originally needed 34 bytes, now needs 35 bytes dsync(john): Error: Sync failed for mbox file /var/opt/migrate/users/john/inbox: seq=114607 uid=114607 uid_broken=0 originally needed 34 bytes, now needs 35 bytes dsync(john): Error: Sync failed for mbox file /var/opt/migrate/users/john/inbox: seq=113993 uid=113993 uid_broken=0 originally needed 34 bytes, now needs 35 bytes dsync(john): Error: Sync failed for mbox file /var/opt/migrate/users/john/inbox: seq=113868 uid=113868 uid_broken=0 originally needed 34 bytes, now needs 35 bytes dsync(john): Error: Sync failed for mbox file /var/opt/migrate/users/john/inbox: seq=113855 uid=113855 uid_broken=0 originally needed 34 bytes, now needs 35 bytes dsync(john): Error: Sync failed for mbox file /var/opt/migrate/users/john/inbox: seq=46725 uid=46725 uid_broken=0 originally needed 32 bytes, now needs 34 bytes What exactly is this error indicating and how can I fix it?

[Dovecot] Dovecot 2.1.16: Quota plugin compile fails: Solaris 10

[Dovecot] LDAP attribute as shared mailbox name
by Marek Skubela 16 Apr '13

16 Apr '13

Hello, Is it possible to use LDAP attribute (cn in my case) instead of e-mail address as a shared folder name, so users would see something like: Shared > ExampleCompany Service and not the default Shared > service(a)example.com? -- Regards, Marek Skubela

[Dovecot] [PATCH] mailbox_get_metadata() for mailboxes with open transactions.
by Dafan Zhai 16 Apr '13

16 Apr '13

Hi everyone, I am writing a dovecot statistic plugin, which calls mailbox_get_metadata() to get the virtual size of the mailbox, if a mail is copied. I have noticed that mailbox_get_metadata() calls mailbox_sync(), and mailbox_sync() will fail for the mailboxes with open transactions. But if a mail is copied, there must be at least one transaction opened for the mailbox. So I can not get the virtual size. Commit [1] has fixed the same problem in mailbox_get_status(). I think the same should also be done in mailbox_get_metadata(). See the patch below. Dovecot version: 2.2.0 OS: OS: Linux 3.4.39-dist i686 maildir:~/Maildir:LAYOUT=fs:INBOX=~/Maildir/INBOX Dafan [1] http://hg.dovecot.org/dovecot-2.2/rev/12136db6e31f # HG changeset patch # User Dafan Zhai <dafan.zhai(a)securepoint.de> # Date 1366118323 -7200 # Node ID 7f0c5122d863d303ef5e74bbf650c2bac89ac564 # Parent f33bacb03cc22e02ca2d11d527d8dc0d99214486 lib-storage: mailbox_get_metadata() no longer forces mailbox to be synced.

[Dovecot] Dovecot 2.2 multiple master user passdb's not working anymore
by Christian Wiese 16 Apr '13

16 Apr '13

Hi, after an update from dovecot 2.1.16 to 2.2.0 I encountered a problem when using multiple master user passdb's like the following: ----%<--------------------------------------------------------- passdb { args = /etc/dovecot/passwd.foo-master driver = passwd-file master = yes } passdb { args = /etc/dovecot/passwd.bar-master driver = passwd-file master = yes } ----%<--------------------------------------------------------- The former behavior that the passdb's are searched sequentially to find the given master user doesn't seem to work anymore. Only the first passdb is searched, and thus authentication will fail for all master users which are not defined in the first passdb. Because I cannot find any hint that the master user handling has changed fundamentally it looks like a bug, but maybe I missed configuration related changes from 2.1 to 2.2 that is causing this new behavior. Cheers, Chris

[Dovecot] Probs authenticating to Dovecot
by Kris Magnusson 16 Apr '13

16 Apr '13

Hi folks. I have set up a Ubuntu 12.04 VM with Dovecot, Postfix, MySQL, amavisd, and ISPConfig 3. The VM has tons of RAM and disk and processor and is permanently connected to the Internet with a static IP. I followed the instructions at howtoforge.com to set up and configure this VM and am using ISPConfig to set up a mail hub for multiple domains. I have the DNS for my other domains' MX records pointing at this host—we'll call it "mail." Here's the version of Dovecot I'm using: root@mail:# dovecot --version 2.1.7 Anyway, when I try to connect to my VM and Dovecot using Mail.app on Mountain Lion, I get the following messages in mail.log: Apr 15 01:18:40 mail postfix/smtpd[4284]: connect from 50-196-170-xxx-static.hfc.comcastbusiness.net[50.196.170.xxx] Apr 15 01:18:40 mail dovecot: auth-worker(4331): mysql(localhost): Connected to database dbispconfig Apr 15 01:18:42 mail postfix/smtpd[4284]: warning: 50-196-170-xxx-static.hfc.comcastbusiness.net[50.196.170.xxx]: SASL PLAIN authentication failed: Apr 15 01:18:42 mail postfix/smtpd[4284]: disconnect from 50-196-170-xxx-static.hfc.comcastbusiness.net[50.196.170.xxx] Apr 15 01:18:54 mail dovecot: imap-login: Disconnected (auth failed, 1 attempts in 6 secs): user=<kris>, method=PLAIN, rip=50.196.170.xxx, lip=50.196.170.yyy, TLS, session=<wwn85mHa8AAyxKq9> Apr 15 01:19:04 mail dovecot: imap-login: Disconnected (auth failed, 1 attempts in 10 secs): user=<kris>, method=PLAIN, rip=50.196.170.xxx, lip=50.196.170.yyy, TLS, session=<XGdT52Ha8QAyxKq9> But if I run alpine on mail, I can send and receive mail all day long. Here's a log entry that demonstrates this: Apr 15 01:20:01 mail postfix/smtpd[4284]: connect from localhost[127.0.0.1] Apr 15 01:20:01 mail postfix/smtpd[4284]: lost connection after CONNECT from localhost[127.0.0.1] Apr 15 01:20:01 mail postfix/smtpd[4284]: disconnect from localhost[127.0.0.1] Apr 15 01:20:01 mail dovecot: pop3-login: Disconnected (no auth attempts in 0 secs): user=<>, rip=127.0.0.1, lip=127.0.0.1, secured, session=<FGhS62HaIwB/AAAB> So I thought it was a problem with SASL not liking PLAIN authentication. When I go to /etc/dovecot and print the contents of dovecot.conf, I see that auth_mechanisms = plain login. root@mail:/etc/dovecot# more dovecot.conf listen = *,[::] protocols = imap pop3 auth_mechanisms = plain login disable_plaintext_auth = no log_timestamp = "%Y-%m-%d %H:%M:%S " mail_privileged_group = vmail ssl_cert = </etc/postfix/smtpd.cert ssl_key = </etc/postfix/smtpd.key passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } userdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } plugin { quota = dict:user::file:/var/vmail/%d/%n/.quotausage sieve=/var/vmail/%d/%n/.sieve } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { group = vmail mode = 0600 user = vmail } user = root } protocol imap { mail_plugins = quota imap_quota } protocol pop3 { pop3_uidl_format = %08Xu%08Xv mail_plugins = quota } protocol lda { mail_plugins = sieve quota } At this point I'm not sure what to think about this. The mailbox is created, it works on the host, so why wouldn't it work over the network? I've tried frobbing settings in Mail.app, as it does have some wonkiness to it, but no dice. The password is fine, everything is in place, it just doesn't work. Any thoughts or recommendations? Thanks, Kris

[Dovecot] [OT] xi.rename-it.nl dovecot-2.2 stable-auto
by Jan Phillip Greimann 16 Apr '13

16 Apr '13

Hi there, I check my mail-server for debian package-upgrades with Nagios, so everyday I got a mail for 8 "new" dovecot-packages on this server. I think that wasn't so in 2.1 stable-auto, but I'm not sure about that. Maybe someone who uses the 2.1 stable-auto repo could response to this? But 2.2 released only few days ago, maybe the repo-admin hadn't time to change this, or my memory about this is wrong. best regards, Jan

[Dovecot] Dovecot IMAPS and slow reconnections
by Jarrad 16 Apr '13

16 Apr '13

Hi List, I've recently moved from postfix + courier-imap to a new server with postfix + dovecot with a mysql user management. I have it up and running and receiving mail ok but I'm having problems with IMAP connections being slow. I have an iphone with multiple imap accounts set up on it (4 I think) and when I open the mail app it connects to first account quickly. Then if I navigate to another account it takes about 1 minute to connect (sits there with the 'connecting....' status) Looking at the logs it shows the connection come through at the same time the iphone actually connects so it's as if something is timing out before it actually connects. My setup is an Amazon EC2 micro instance running debian wheezy. There is about 5 domains being hosted with approximately 4-5 accounts for each so it's not a heavy load by any means. I've tried bumping up the max connections, service_count and minimum processes but nothing seems to help. Any advice is much appreciated. My config is as per below: # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-4-amd64 x86_64 Debian 7.0 ext4 auth_debug = yes auth_verbose = yes disable_plaintext_auth = no mail_location = maildir:/var/vmail/%d/%n/Maildir 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 { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } protocols = " imap pop3" service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-master { group = vmail mode = 0600 user = vmail } } service imap-login { process_min_avail = 5 service_count = 10 } ssl_cert = </etc/dovecot/dovecot.pem ssl_key = </etc/dovecot/private/dovecot.key userdb { args = uid=5000 gid=5000 home=/var/vmail/%d/%n/Maildir allow_all_users=yes driver = static } verbose_ssl = yes protocol lda { auth_socket_path = /var/run/dovecot/auth-master log_path = mail_plugins = postmaster_address = <removed for spam reasons> } protocol imap { mail_max_userip_connections = 100 }

[Dovecot] SSHA512 auth not working
by Marcin Czupryniak 16 Apr '13

16 Apr '13

I'm trying to configure SSHA512 passwords and when testing discovered that they were not working as expected. At first i was using Centos 6.4 which doesn't have the glibc CRYPT newest functions ($6$salt$pass) so had to rollback to the Dovecot format ({SSHA512.HEX}saltedpassword+salt ) but I'm unable to let dovecot authenticate properly. Some logs and details: Apr 16 02:55:37 auth: Debug: client in: AUTH 1 PLAIN service=imap lip=xxx rip=xxx lport=143 rport=58171 resp=AGRpbm9AYWJjLml0AGRpbm8= Apr 16 02:55:37 auth: Debug: sql(dino(a)abc.it,xxxx): query: SELECT '{SSHA512.HEX}' || password as password FROM mailboxes WHERE fullusername='dino(a)abc.it' Apr 16 02:55:37 auth: Info: sql(dino(a)abc.it,xxxx): Password mismatch (given password: dino) Apr 16 02:55:37 auth: Error: md5_verify(dino(a)abc.it): Not a valid MD5-CRYPT or PLAIN-MD5 password Apr 16 02:55:37 auth: Warning: Invalid OTP data in passdb Apr 16 02:55:37 auth: Warning: Invalid OTP data in passdb Apr 16 02:55:37 auth: Debug: sql(dino(a)abc.it,xxxx): SSHA512.HEX(dino) != 'd449914d83c85a786bcde7114b3dfdb24a651c27956388ac641d46eaf40c86e7c95ce2534348730475c8893eab314af189b3a46bf6d76b82cfba119e920813a531e985acd35c47ca8d3cafe50b595b66' Apr 16 02:55:39 auth: Debug: client out: FAIL 1 user=dino(a)abc.it Full password as taken from database: {SSHA512.HEX}d449914d83c85a786bcde7114b3dfdb24a651c27956388ac641d46eaf40c86e7c95ce2534348730475c8893eab314af189b3a46bf6d76b82cfba119e920813a531e985acd35c47ca8d3cafe50b595b66 The first 128 chars are the salted password, remaining 32 the salt (hex uuid representation) I've checked twice that the generated passwords are correct, in fact if you salt the password (dino) you get the exact 128chars as in the stored password but dovecot compares the full password with the salt (160 chars), is this correct? Any ideas?

[Dovecot] rsync migration issue
by Luigi Rosa 16 Apr '13

16 Apr '13

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I am trying to migrate a mail server from an old VM to a new one. I have maildir and virtual users, the files and dirs of the file system are owned by a single user. I exported the old (now in production) /var/spool/mail with (ro,no_root_squash) parameters I mounted the NFS on the new server with -o nolock This is not the first time I use this method and it always worked. Until now. If I try to rsync the current maildir structure to the new server I get MANY errors like: rsync: readdir("/mnt/xxxx/username"): Invalid argument (22) rsync: readdir("/mnt/xxxx/username/.Deleted Messages/cur"): Too many levels of symbolic links (40) I tried with rsync -a rsync --force --delete-after --devices --specials --sparse -tPrlHpogEAX rsync --force --delete-after --devices --specials --sparse -tPrlHpogEAXL but the result is the same. Suggestions? I don't want to tgz every mailbox, but I wuold like to do a rsync during the night and a final rsync bevore switching IP addresses to minimize downtime.

[Dovecot] Delete_to_Trash plugin problem
by BINOTTO Luis SIDOR 15 Apr '13

15 Apr '13

Hello list... I am new at dovecot and I have a problem with it; any help will be very grateful We have a exchange server with outlook at the client side, and we are migrating the exchange server to postfix/dovecot(1.2.15) solution. I enabled the "deleted-to-trash" plugin (v0.3) to move the messages to the Trash folder automatically when it is deleted. Also, I am using quota and quota_imap plugins to maintain the quota for users. The quota rule for Trash folder is unlimit. The problem is, when the client reach their maximum quota and try to delete a mail in the inbox to release space. The delete to trash plugin effectively copy it to the Trash folder, but the original mail still remain (marked for delete) at the inbox folder and the quota does not released. Am I doing something wrong? Thanking you in anticipation.... Luis Binotto. " Notificacion Automatica: Este mensaje y cualquier archivo que se adjunte contiene informacion privilegiada y confidencial.

[Dovecot] Dict quota question
by Antoine Nguyen 15 Apr '13

15 Apr '13

Hi all, I'm using Dovecot 2.1.16 and I'd like to know if the following configuration is supported: * An SQL dictionary quota * A static userdb to get uid/gid/home information * An SQL userdb to get per-user quota limit Currenlty, current quota usage are properly stored into the database but per-user limits are not found. If I replace the SQL dictionary by the maildir backend (my previous config.), it works as expected. Do you have any idea? Thanks in advance, Antoine Nguyen http://modoboa.org/

[Dovecot] lazy_expunge plugin with virtual mailboxes
by Gilles Chauvin 15 Apr '13

15 Apr '13

Hi, When using both lazy_expunge and virtual mailboxes (with, for instance, a "All Messages" virtual mailbox) as soon as a user deletes/expunges a mail in one of its mailbox, Dovecot is saving two mails to the lazy_expunge namespace (the one in the user mailbox and the one in the virtual mailbox). Is there some kind of trick to make Dovecot ignore any mail deleted from a virtual mailbox namespace ? Thanks, Gilles.

The out would be proportional to the length of your input password if the were encrypting, rathher than hashing. But the length of the hash is consant + encoded(salt) + encoded (hash(password)), all of which ought to be fixed lengths. Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] How to manually generate a password hash
by David Murphy 14 Apr '13

14 Apr '13

Hi folks. I've recently set up a Postfix 2.9.6/Dovecot 2.0.19 IMAPS/SMTPS setup on Ubuntu 12.04.2 (Mysql backend). I'm new to all this, so I apologize if this is fairly basic. I've attempted to the best of my ability to search for an answer, but no luck so far. What I'm trying to do is generate a password hash that I can inject directly into my Mysql database (disaster recovery sort of situation). Towards that goal, I'm trying to use 'doveadm pw' to generate a hash that matches a known password in my database. Unfortunately, I'm coming up empty. My default_pass_scheme in dovecot-sql.conf is set to MD5-CRYPT, and the passwords in the database have no scheme prefixes. I'm attempting to generate a hash with: sudo doveadm pw -s 'MD5-CRYPT' but the hash generated does not match the user's password hash in the database, which is known to be a good password. I'm able to log into this account successfully in both Roundcube and a remote IMAP client. I've also tried using the -p flag and including the password in the command, and that doesn't do it either, though it oddly gives a different response than using the prompt. (What causes this? Newlines?) So... what am I missing? If the hash was salted, it would seem the hashes in the database would be longer than the ones generated at the command line, but that isn't the case. I'm out of ideas. Any guidance appreciated. -Dave

[Dovecot] LMTP Setup/Design Help Request
by Matthias Hofer 13 Apr '13

13 Apr '13

Hi again, Thank you for your first hints. I have now set up a dedicated test instance of postfix and dovecot to be able to recreate the problems in detail. Even after using your inputs, they do not seem to work with my setup I already mentioned above. I get errors like postfix/lmtp[10994]: C2DF4C000DF: to=<user1(a)mydomain.org>, relay=mail.mydomain.org[private/dovecot-lmtp], delay=0.1, delays=0.05/0/0/0.04, dsn=5.1.1, status=bounced (host mail.mydomain.org[private/dovecot-lmtp] said: 550 5.1.1 <user1(a)mydomain.org> User doesn't exist: user1(a)mydomain.org (in reply to RCPT TO command)) As stated before, my setup is as follows: > I only have virtual users and have set > > mail_uid = dovemail > mail_gid = dovemail > > For authentication, I simply use (for now) a flat file: > > passdb { > driver = passwd-file > args = scheme=PLAIN username_format=%u /etc/dovecot/mypasswd.file > } > > # cat /etc/dovecot/mypasswd.file > user1:{PLAIN}userpw1 > user2:{PLAIN}userpw2 > user3:{PLAIN}userpw3 > > And everything works fine with IMAP. I am completely domain-agnostic > here. I do not know how to strip the domain when the username is handed over from postfix to dovecot, and what would be the sane solution. I hope, you can give me a hint to that. Thank you, again, and greetings, Matthias Hofer

Putting pop3 in /etc/hosts.deny with the associated ip seems to work, like so: pop3: 166.84.1.2 or imap imap: 166.84.1.2 (are there any challenges to this?) Given that services such sendmail and sshd respond to sshd: xxx.xxx.xxx.xxx sendmail: xxx.xxx.xxx.xxx I thought that it should be dovecot: xxx.xxx.xxx.xxx As a suggestion, can dovecot binaries for distributions such as CentOS and Fedora be compiled with tcp wrappers by default? > - Richard Much thanks.

[Dovecot] Questions about the upcoming Object Storage Plugin for 2.2
by Charles Marcus 11 Apr '13

11 Apr '13

Hi Timo, I'm curious and have questions about the new Object Storage Plugin (OSP), and how it can be leveraged by an SMB like us. First, am I reading this right where it could be used as a kind of 'live/realtime backup' solution, where everything is stored *both* locally and in the cloud, with two-way syncing, ie, so local users could access the local server for faster access, and when outside the office, they'd access the cloud based storage and any changes made there are sync'd back to the local server? Or is it intended to be more as an alternative storage for storing older emails in a separate namespace? Or both/either? Second, is SIS fully supported by the OSP? Third - I'm a little confused by the Amazon S3 pricing page, especially on how to try to estimate the costs for usage (bandwidth, etc)... do you have any idea how to go about estimating that? Is there some kind of process we could use on our existing server to measure it over a given period of time that would give us an estimate of what to expect if we decided to switch over? Last - have you established pricing for the OSP? Will it be per user, or per MB/GB, per month (or per year), or just a one-time cost? And/or will you include/bundle it with any/all of your support tiers? Sorry if I'm jumping the gun here... Thanks, really looking forward to the 2.2 release! -- Best regards, Charles

Sorry for top posting, but I have no additional info on this. BTW I need to refresh the question as I have tried squat, and I'm biting the dust with the already known problems ( "Corrupted squat uidlist file" or "Panic: file squat-trie.c:" ). Is there some pointer on where/how to find assist on fts-lucene to keep on analisys for this problem on sparc ? T.I.A.

Greetings, I am looking to implement tcp wrappers with dovecot; I am using the following two links as guides to configuration: http://blog.acsystem.sk/linux/brute-force-attack-dovecot-imap-server-blocki… http://wiki2.dovecot.org/LoginProcess (you need to go to the very bottom) I'm concerned in making the configuration correctly. If you set login_access_sockets = tcpwrap in /etc/dovecot/dovecot.conf Then everything accessing ports controlled by dovecot (and open by iptables) is blocked. So my question relates to the second part of the configuration examples in the links above: service tcpwrap { unix_listener login/tcpwrap { group = $default_login_user mode = 0600 user = $default_login_user } } Where does this code get placed (in dovecot.conf or in one of the files in /etc/dovecot/conf.d)? And regarding $default_login_user, it appears in a comment line in /etc/dovecot/conf.d/10-master.conf Should that line be uncommented? Much thanks.

[Dovecot] [PATCHES] NetBSD support, authentication buffer size
by Emmanuel Dreyfus 11 Apr '13

11 Apr '13

Hi Here are a few unintegrated patches, just tested against 2.2rc7: 1) NetBSD's getmntinfo uses struct statvfs while other BSD use struct statfs http://ftp.espci.fr/shadow/manu/patch-ak 2) NetBSD 5.x net_getunixcred() support. Build on NetBSD, but not tested (I am testing on NetBSD 6.0): http://ftp.espci.fr/shadow/manu/patch-src_lib_net.c 3) Increase authentication buffer size so that it can cope with unusual authentication scheme. This patch was integrated in dovecot-1.x but did not make its way in dovecot-2.x http://ftp.espci.fr/shadow/manu/patch-src_lib-master_master-auth.h -- Emmanuel Dreyfus manu(a)netbsd.org

[Dovecot] Easy way to make all mailboxes of a user read-only
by Stephan von Krawczynski 11 Apr '13

11 Apr '13

Hello all, I try to configure dovecot to make all imap accesses read-only for a certain user. I thought this would be possible by creating a global acl file (here "global-acl") like: user=<username> lr and plugin { acl = vfile:/etc/dovecot/global-acls:cache_secs=300 } But that seems to be ignored. What is wrong with this idea, the docs are not really clear about a single acl file with global settings. -- Regards, Stephan

[Dovecot] v2.2.rc7 released
by Timo Sirainen 11 Apr '13

11 Apr '13

http://dovecot.org/releases/2.2/rc/dovecot-2.2.rc7.tar.gz http://dovecot.org/releases/2.2/rc/dovecot-2.2.rc7.tar.gz.sig OK, still not quite v2.2.0, but now it's definitely very close. :) * checkpasword: AUTH_PASSWORD environment is no longer set. * Running dsync no longer triggers quota warnings. + dsync: Commit large transactions every 100 new messages, so if a large sync crashes it doesn't have to be restarted from the beginning. - replicator: doveadm commands and user list export may have skipped some users. - Various fixes to mailbox_list_index=yes

[Dovecot] Dovecot distribution configuration files source
by Dave Gattis 11 Apr '13

11 Apr '13

Where can I find unaltered distribution config files (/etc/dovecot/ and /etc/dovecot/config.d/) for Dovecot 2.1.7? I upgraded from version 1 and had to butcher them to get it working. Now that I understand it better, I'd like to do it right. -- Dave

[Dovecot] My old email is not stored
by HylkeB 11 Apr '13

11 Apr '13

Hi, Im have not much experience with dovecot, postfix or debian, which i am using for my email server. But the thing is, everything worked just fine, until I found out that old emails were missing, only emails of a few months old exist on my server. I have no idea if this is a setting in dovecot, postfix or debian, or that something weird happened. But my question is, is there a setting in either dovecot, postfix or debian that i should check that could cause this behaviour, and if so, how do i check that? (opening and checking a conf file for example, or executing some commands in PuTTy). And if this is somehow default behaviour that cannot be changed, is there some other way to store all emails ever entered my inbox? Sincerely, Hylke Bron -- View this message in context: http://dovecot.2317879.n4.nabble.com/My-old-email-is-not-stored-tp41478.html Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] Proxying, pertinent values and features, SNI
by Christian Balzer 11 Apr '13

11 Apr '13

Hello, I'm looking into deploying dovecot as a proxy, currently using perdition. Have been using dovecot on the actual servers for years, nearly a decade. So far just 1.x, but for the proxy it will have to be 2.x (2.1.7 is the current Debian version), as the trigger for this change is the need to support multiple SSL certificates. All that happens on the proxy seems to be handled by the login processes, so that is why we're not seeing anything useful in the process titles or with doveadm, right? And from past comments by Timo I guess that adding such functionality isn't on his to-do list at all. A configurable capabilities string for POP would be quite welcome, but at least nothing is different between the 1.x backends and the 2.x proxy in that protocol. Speaking of 1.x versus 2.x, the feature to pass on the remote IP from the proxy to the backend is a 2.x thing only, correct? So I suppose any parameters really affecting this setup are default_process_limit and default_client_limit as well as the settings in service-imap-login and service pop-login. In particular mail_max_userip_connections never is looked at on the proxy as this check happens in the respective protocol AFTER login, rite? I presume to best support all(?) clients out there is to have "local_name" sections for SNI first and then "local" sections for IP address based certs. It is my understanding that SNI needs to be requested by the client, so aside from client bugs (nah, those don't exist ^o^) every client should get an appropriate response for TLS. Has anybody done a setup like that already? Regards, Christian -- Christian Balzer Network/Systems Engineer chibi(a)gol.com Global OnLine Japan/Fusion Communications http://www.gol.com/

[Dovecot] [PATCH proposal] make dsync preserve pop3_uidl_format
by Mark Zealey 11 Apr '13

11 Apr '13

Hi there, I ran into an issue yesterday (dovecot 2.0) whereby when we dsync messages from a local machine (sdbox) to a remote (Maildir) which have different pop3_uidl_formats configured, the uidl format is not preserved. There doesn't seem to be any way to force this in the code, although I suspect that Maildir sources with saved pop3 uidls would pass them correctly. Attached is a rough patch against 2.0.21 dsync which will generate the uidls on the client before passing them over to the destination. This only works for %u and %v currently, also because dsync doesn't read the whole config file you need to specify -o pop3_uidl_format=... to dsync. Mark

[Dovecot] Postfix/Dovecot/lmtp with virtual and local users
by David Obando 11 Apr '13

11 Apr '13

Hi all, I'm about to change my Debian mailserver setup from Postfix/dovecot1/procmail to Postfix/dovecot2/sieve with lmtp enabled. After enabling lmtp the virtual users can receive e-mails but not the local users: Mar 21 14:21:40 orange postfix/lmtp[4119]: DE62226216: to=<user(a)orange.domain.de>, relay=orange.domain.de[private/dovecot-lmtp], delay=7627, delays=7627/0/0/0.02, dsn=5.1.1, status=bounced (host orange.domain.de[private/dovecot-lmtp] said: 550 5.1.1 <user(a)orange.domain.de> User doesn't exist: user(a)orange.domain.de (in reply to RCPT TO command)) In 10-auth.conf I have the setting "auth_username_format = %Lu". When changing it to "auth_username_format = %n" the local users can be found but not the virtual users anymore. Is there a way to define "if <user> is local then auth_username_format = %n else auth_username_format = %Lu"?

[Dovecot] Pigeonhole 0.3.4: Warning: sieve: encountered corrupt binary: re-compiling script
by Daniel Piddock 10 Apr '13

10 Apr '13

Hi all, Upgraded to Dovecot 2.1.16 and Pigeonhole 0.3.4 yesterday. We use lmtp and sieve. I've now started to see in the logs the following entries: >Warning: Jz6kNv8AY1FdfQAAVMeomg: sieve: encountered corrupt binary: re-compiling script [script path] The script then appears to run correctly and the message gets stored where ever it should be. This only appears to be happening for a few users and although it happens on the majority of their messages it doesn't happen for every single one. What's the best way to start debugging? Thank, Dan

[Dovecot] thunderbird detach attachment
by mourik jan heupink 10 Apr '13

10 Apr '13

Hi all, Thunderbird has an option to detach attachments from (for example) sent items. I've tried it, and it does not work, and also in the dovecot logs I don't see anything interesting meanwhile. Before looking deeper into this: Does anyone here know if this option is known to work, or not? We're running dovecot 2.1.7 on debian wheezy. Removing unwanted attachments is a nice way to keep mail archives smaller... Thanks, MJ

[Dovecot] How to see folders/subfolders/emails through imap
by Stephan von Krawczynski 10 Apr '13

10 Apr '13

Hello all, I am trying to do something very simple - at least thats what I thought. I have some fs, it contains folders and subfolders with email files ordered like maildir. Now I try to set up dovecot on top simply to let some imap account watch these email files. But I cannot see any folders at all. I can create new folders and see them, but I cannot create subfolders as subdirs like "folder/subfolder". Instead I get "folder.subfolder" dirs on the fs. I tried to set the separator to "/", but that does not help at all. Is there some easy way to configure dovecot to display: <somedir>/<folder1>/<subfolder1>/new/files... <subfolder2>/new/files... <subfolder3>/new/files... according to fs layout on some imap-client (like thunderbird)? -- Regards, Stephan

You probably want to compile in tcp_wrapper support and handle it that way http://wiki2.dovecot.org/LoginProcess You might also hook into a the post-login script if you need some bizarre logic to determine whether to allow a login or not, but this is later in the session setup rather than block-on-sight like a firewall. http://wiki2.dovecot.org/PostLoginScripting Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] How to exec /usr/libexec/dovecot/imap with specific maildir location
by David Woodhouse 09 Apr '13

09 Apr '13

Once upon a time I could configure my mailer to access my historical archives by running something like ssh $mailserver MAIL=maildir:~/Maildir-archive dovecot --exec-mail imap I need to run /usr/libexec/dovecot/imap manually now, and I've fixed that a while ago for my normal email access. But I've just had cause to go back to my archives for the first time in a while... and realised that I don't know how to make it work any more. When invoking /usr/libexec/dovecot/imap, is there an environment variable or command line option which can set the mail location? -- dwmw2

Does Dovecot have a facility to block pop3 and imap logins by IP address. I usually do this by putting the IPs in my border firewall, but it's in transition currently to a new one, and I'd like to end connection fairly fast. If it matters, I'm using 2.0.9. Thanks steve campbell

[Dovecot] Received date on emails is wrong after file copying
by maia＠weiser.dk 09 Apr '13

09 Apr '13

Hi, I have installed a new mail server where I'm migrating from Courier to Dovecot. I have made a mistake when I was copying over the emails so the date/time mark on them is updated. So all my mails are now from the copy date/time and not the real receive time. I have tried to copy the emails over again, so they get the right date/time on the file level. And when I look at a single email in details in SquirrelMail it has now the right date/time, but when I look at the overview of a folder it still have the copy date/time on them. Is there any way to get the date/time in the overview updated, maybe delete some index files or force it to re-index? I'm not even sure that the problem is in Dovecot. But I'm sure You can help me here. Best Regards, Kim Johansen

[Dovecot] LMTP Setup/Design Help Request
by Matthias Hofer 09 Apr '13

09 Apr '13

Hi altogether, I am switching from dbmail 2.2 to dovecot 2.1.7, and I was able to do a successful transition of IMAP. But I had a very hard time with receiving mail, and in the end -- after loads of reading and debugging -- I broke down and failed. This is why I am asking you for your kind help. I only have virtual users and have set mail_uid = dovemail mail_gid = dovemail For authentication, I simply use (for now) a flat file: passdb { driver = passwd-file args = scheme=PLAIN username_format=%u /etc/dovecot/mypasswd.file } # cat /etc/dovecot/mypasswd.file user1:{PLAIN}userpw1 user2:{PLAIN}userpw2 user3:{PLAIN}userpw3 And everything works fine with IMAP. I am completely domain-agnostic here. But I was not able to use this fine setup to receive mails with my postfix. I tried about 13 different configurations, some with considerable changes dovecot-config, the passwd-file or postfix, but I could not find a single variant working. In this situation, I would be very happy if somebody could give me a hint, which would be the prudent way to configure dovecot, LDA/LMTP and postfix based on the setup above. Thank you very much in advance, and have a great time, Matthias Hofer

[Dovecot] repeating dsync - questions
by Bob Gustafson 08 Apr '13

08 Apr '13

I'm moving/converting email from one system to another The source system is: Dual core x86_64 6GB memory 180 GB raid1 disks ext4 Fedora 9 Dovecot 1.0.15 Maildir format The destination system is: Dual core x86_64 2GB memory 1TB raid1 disks ext4 Fedora 18 Dovecot 2.1.15 sdbox format I am moving mail in a series of steps: 0) cd ( to mail user home directory ) mkdir Maildir 1) # rsync mail from source system (hoho4) to current (hoho0) time rsync -arv --times hoho4:/home/bobgus/Maildir/ /home/bobgus/Maildir/ This step takes about 37 minutes the first time 2) # dsync mirror/convert to sdbox format on current system time dsync mirror maildir:~/Maildir This step takes about 858 minutes (!!) Looking at -D messages indicates that dsync is deciding between duplicates much of the time. Looking at the results in a mail browser (Evolution), it seems fine, although the latest mails are not there. 3) # pick up more current mail - use same script as in 1) time rsync -arv --times hoho4:/home/bobgus/Maildir/ /home/bobgus/Maildir/ This step takes about 5 minutes although this varies depending on the amount of new mail. 4) # repeat the 2) dsync step time dsync mirror maildir:~/Maildir This is where things look peculiar. When I look at the directory of sdbox/mailboxes, I see duplicated directories [bobgus@hoho0 sdbox]$ cd mailboxes [bobgus@hoho0 mailboxes]$ ls Apple Mail To Do Apple Mail To Do_2a47983780615e5179600000ba55d82c Deleted Messages Deleted Messages_2847983780615e5179600000ba55d82c Drafts Drafts_2447983780615e5179600000ba55d82c Important Important_2947983780615e5179600000ba55d82c INBOX INBOX_1547983780615e5179600000ba55d82c Sent Sent_2547983780615e5179600000ba55d82c Trash Trash_2747983780615e5179600000ba55d82c The 2nd dsync step has not completed yet.

[Dovecot] dsync replication: quota counted twice
by Oli Schacher 08 Apr '13

08 Apr '13

Hi I enabled quota + warnings in my replication test setup and now whenever a mail gets delivered the quota is counted twice (probably due to both servers using the same mysql quota backend) and quota warnings are fired too early. After a doveadm quota recalc -u <username> the quota is correct again. How do I make dovecot only count the quota on the server where the mail was added originally? dovecot -n is the same as in my previous message to the list today http://www.dovecot.org/list/dovecot/2013-April/089558.html (thanks Timo for the hint in this thread btw, changing the permissions made the errors go away) Thanks Oli -- message transmitted on 100% recycled electrons

[Dovecot] Dovecot Configuration
by Andreas K. 08 Apr '13

08 Apr '13

Can somebody, please, point me in the right direction in finding a COMPLETE and EXACT definition of the Dovecot configuration hierarchy. In other words what configuration options exist both at the top level but also at each subconfiguration elements (ex. sections etc). While my C is a bit rusty, I can still make sense of source code and with a bit of effort I will figure it out. I have been going through the src/config/all-settings.c but still have large gaps. A hint in the right direction on how the config works might help clarify and speed things up. Thanks Andreas Kasenides

[Dovecot] checkpassword protocol
by dovecot.pkoch＠dfgh.net 08 Apr '13

08 Apr '13

Hi, I'm writing a checkpassword script in order to support our OTP token as a fallback for client certificate authentication. Here are two questions: 1) It seems to me that the username and the password will be delivered to my script both on file descriptor 3 and via the environment variables AUTH_USER and AUTH_PASSWORD. May I ignore file descriptor 3 and use the environment variables or may it happen that these variables will have differnet content from what is sent via fd 3? 2) There seems to be some undocumented interaction between dovecot and my script via file descriptor 4. Seems that whatever I write to fd 4 will show up in syslog (unless it contains newlines). Can I use this "feature" to send error messages from my script to dovecot? What data does dovecot expect on fd 4? Peter

[Dovecot] ssl_require_crl does not work as expected
by dovecot.pkoch＠dfgh.net 08 Apr '13

08 Apr '13

Hi I'm trying to use dovecot with client certificates. We produce our certificates with our on CA and we do NOT use certificate revocation lists. So I put "ssl_require_crl = no" into 10-ssl.conf. I did not find a solution neither in the wiki nor somewhere else, so I finally started to read the source. My impression is that openssl will always try to use CRLs. If "ssl_require_crl = no" dovecot will use CRLs but tries to ignore openssl error codes X509_V_ERR_UNABLE_TO_GET_CRL and X509_V_ERR_CRL_HAS_EXPIRED. This is done in ssl_verify_client_cert() in ssl-proxy-openssl.c line 871, namely i_info("proxy=%d, require_crl=%d, error=%d", proxy->client_proxy, proxy->set->ssl_require_crl, ctx->error ); if (proxy->client_proxy && !proxy->set->ssl_require_crl && (ctx->error == X509_V_ERR_UNABLE_TO_GET_CRL || ctx->error == X509_V_ERR_CRL_HAS_EXPIRED)) { /* no CRL given with the CA list. don't worry about it. */ preverify_ok = 1; } With my setup proxy->client_proxy is 0. I added the i_info() to check this and with this modification my syslog shows: Apr 7 13:01:16 d600 dovecot: master: Dovecot v2.1.15 starting up (core dumps disabled) Apr 7 13:01:21 d600 dovecot: auth: Debug: Loading modules from directory: /usr/dovecot/lib/dovecot/auth Apr 7 13:01:21 d600 dovecot: auth: Debug: auth client connected (pid=26175) Apr 7 13:01:22 d600 dovecot: imap-login: proxy=0, require_crl=0, error=3 Apr 7 13:01:22 d600 dovecot: imap-login: Invalid certificate: unable to get certificate CRL: /CN=...user cert.../C=DE Apr 7 13:01:22 d600 dovecot: imap-login: proxy=0, require_crl=0, error=3 Apr 7 13:01:22 d600 dovecot: imap-login: Invalid certificate: unable to get certificate CRL: /CN=...intermedieate cert.../C=DE Apr 7 13:01:22 d600 dovecot: imap-login: proxy=0, require_crl=0, error=3 Apr 7 13:01:22 d600 dovecot: imap-login: Invalid certificate: unable to get certificate CRL: /CN=Root-CA.../C=DE I dont know what the proxy-stuff is about so instead of ignoring CRL-related errors I tried to disable CRL-checking. I therefore commented out two lines in ssl_proxy_ctx_verify_client() in ssl-proxy-openssl.c line 1004, namely: // X509_STORE_set_flags(store, X509_V_FLAG_CRL_CHECK | // X509_V_FLAG_CRL_CHECK_ALL); This tells OpenSSL not to check CRLs. Of course in production code this should be done only if "ssl_require_crl = no". Similar code is contained in iostream-openssl-context.c, namely in routine ssl_iostream_ctx_verify_remote_cert() Is this a bug? Peter

[Dovecot] client limit and STARTTLS
by David Benfell 08 Apr '13

08 Apr '13

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all, I'm migrating from one system to another. Both are Arch Linux, but copying the configurations and just modifying them for IP addresses and hostnames didn't work. Here's doveconf -n # 2.1.15: /etc/dovecot/dovecot.conf doveconf: Warning: service auth { client_limit=256 } is lower than required under max. load (3072) doveconf: Warning: service anvil { client_limit=256 } is lower than required under max. load (2051) # OS: Linux 3.8.4-1-ARCH x86_64 base_dir = /var/run/dovecot/ default_client_limit = 256 default_process_limit = 1024 login_trusted_networks = 10.8.0.0/16 127.0.0.0/8 mail_location = maildir:~/Maildir mail_max_userip_connections = 30 passdb { args = failure_show_msg=yes driver = pam } service auth { unix_listener /var/spool/postfix/private/auth { mode = 0666 } } ssl_cert = </big/www/ssl/www.cybernude.org_publickey.pem ssl_key = </big/www/ssl/www.cybernude.org_privatekey.pem userdb { driver = passwd } Obvious first question: I can't figure out how to make dovecot happy with the client and process limits. I'm not terribly worried about going overboard here, though I have a very small number of users; the migration is to a much more capable system. But I would like to stop looking at the warning. It doesn't seem to matter what I put where--it keeps complaining. Second question: STARTTLS isn't working. What am I missing? Sorry if this is something that should be obvious; I'm fighting a similar battle with postfix and I'm being pushed around the bend while I really need to be working on other things.

[Dovecot] v2.2.rc6 released
by Timo Sirainen 08 Apr '13

08 Apr '13

http://dovecot.org/releases/2.2/rc/dovecot-2.2.rc6.tar.gz http://dovecot.org/releases/2.2/rc/dovecot-2.2.rc6.tar.gz.sig Some more fixes to bugs I noticed today while trying out some new things in production. Note especially the replicator-doveadm socket change, see http://wiki2.dovecot.org/Replication for how to configure it. This change allowed local replicator to notify the remote replicator about user being synced. * replicator: Don't create replicator-doveadm socket by default. This way doveadm replicator commands don't accidentally start an unconfigured replicator server. + replicator: Have remote dsync notify the remote replicator that a user was just synced. This way the replicators are kept roughly in sync. + Added ssl_client_ca_file to specify the CA certs as a file. This is needed (instead of ssl_client_ca_dir) in RedHat-based systems. + Added "doveadm fs" commands, mainly to debug lib-fs backends. - Mailbox list indexes weren't using proper file permissions based on the root directory.

[Dovecot] mdbox and folders containing both messages and sub-folders
by Rich Wales 08 Apr '13

08 Apr '13

I've got Dovecot 2.2r5 (Ubuntu package version 2:2.2.0~rc5-0~auto+1 from the "testing-auto/dovecot-2.2" repository on xi.rename-it.nl) running on a brand-new Ubuntu 12.04.2 server. I'm trying to configure Dovecot (using the "mdbox" mailbox format) to allow folders to contain both messages and sub-folders. However, it's not working consistently. I need to have folders with both messages and sub-folders because I'm trying to migrate mail from an existing (but soon-to-be-retired) Cyrus server, and the existing body of mail has folders of this sort. I'm currently using the following configuration line: mail_location = mdbox:~/mdbox:DIRNAME=.indexes:INDEX=~/mdbox/indexes and am using the Larch program to do an IMAP-to-IMAP copy of one of my family member's mail from the old Cyrus server to the new Dovecot server. When I examine the "mailboxes" directory tree, I see some directories that (correctly) contain both the renamed ".indexes" directory and also directories for IMAP subfolders. However, the Larch output is showing many errors of the form "mailbox cannot contain messages", and some of the messages could not be migrated because of this problem. Am I doing something wrong? Or is the "folders containing both messages and sub-folders" feature simply broken for the "mdbox" format -- meaning presumably that I'll be forced either to use the Maildir format, or else abandon Dovecot entirely and install Cyrus on my new mail server instead?

[Dovecot] autocreate mailbox but no sub folders
by Arnaud Abélard 07 Apr '13

07 Apr '13

Hello, We have been using lda_mailbox_autocreate to avoid to intialize empty mailboxes upon account creations. This does the job allright except that dovecot-lda is also allowed to autocreate sub folders which is a problem when using addresses extensions (adress+folder(a)domain.tld) It's easy for a malicious user to flood a mailbox with tons of subfolders. Is there a way to tell dovecot-lda it can only create the initial mailbox and maybe some special folders but nothing else?

[Dovecot] replicator/dsync over tcp
by Michael Grimm 07 Apr '13

07 Apr '13

Hi -- I am testing replicator/dsync over tcp, and I did run into some issues. First of all I did need to extend http://wiki2.dovecot.org/Replication to get dsync over tcp running without ssl: | # dsync over tcp default port | # | doveadm_port = 12345 | service doveadm { | # running dsync over tcp and using ssl | # added-->| user = vmail | inet_listener { added-->| address = 1.2.3.4 | port = 12345 | # ssl = yes | } | } | plugin { | # this host replicates to remote host | # | mail_replica = tcp:SERVER-A.TLD That didn't work ... | dovecot: doveadm(test): Error: doveadm_password not set, can't authenticate to remote server ... thus, I needed to add: added-->| local 1.2.3.4 { added-->| # password for client authentication by doveadm server added-->| # added-->| doveadm_password = secret added-->| # allow client to only use specified list of commands (default is all): added-->| # added-->| #doveadm_allowed_commands = added-->| } 1. Question: may one include "secret" from a file? Well, that runs like a charm! Now, I did try to add ssl by activating "ssl = yes" in 'service doveadm' (see above) and adding ... | # used by replicator/dsync over tcp | # | ssl_client_ca_dir = /<path-to>/ssl/certs ... and ... | mail_replica = tcps:SERVER-A.TLD But, this didn't work (logfile at remote server): | dovecot: doveadm(test): Invalid certificate: self signed certificate: /OU=dovecot server/CN=OTHER-NAME.TLD/emailAddress=postmaster(a)OTHER-NAME.TLD | dovecot: doveadm(test): Error: SERVER-A.TLD: Received invalid SSL certificate | dovecot: doveadm(test): Error: sync: Disconnected from remote The OTHER-NAME.TLD is served by my additional settings used by my MUAs: | ssl_cert = </<path-to>/ssl/certs/OTHER-NAME.TLD.pem | ssl_key = </<path-to>/ssl/private/OTHER-NAME.TLD.pem I did supply SERVER-A.TLD certs and private certificates at both servers as well, but dovecot seems to use those of OTHER-NAME.TLD for replicator/dsync instead :-( 2. Question: May I config the certificate that should be used for replicator/dsync and that might be different from those used by my MUAs (other then pointing to '/<path-to>/ssl/certs')? I am quite sure that I screwed my config somehow, but I cannot find the cause. Thus, someone? Thanks, and with kind regards, Michael

This loses much of the security benefits of the login process design, because in case of a security hole (in Dovecot or SSL library) the attacker is now able to see other users logging in and steal their passwords, read their mails, etc. Default client_limit * process_limit = 1000*100 = 100k connections vsz_limit should be increased to avoid out of memory errors, especially if you're using SSL/TLS.

[Dovecot] The sieve_extprograms plugin included in main Pigeonhole 0.4 source tree
by Stephan Bosch 07 Apr '13

07 Apr '13

Hi, I think the sieve_extprograms is mature enough for an initial release and that is why I've included the sieve_extprograms plugin into the main Pigeonhole v0.4 source tree. It is still a plugin, but is no longer provided as a separate package. This should make things easier. It will be released along with Pigeonhole v0.4.0. Regards, Stephan.

[Dovecot] Released Pigeonhole v0.3.4 for Dovecot v2.1.16
by Stephan Bosch 06 Apr '13

06 Apr '13

Hello Dovecot users, Much time passed since I last released a new Pigeonhole, so quite a few unreleased fixes were pending until now. Development of new features is shifted to the upcoming Pigeonhole v0.4 for Dovecot v2.2. I intend to release v0.4.0 shortly after Dovecot v2.2.0. Changelog v0.3.4: * Changed error handling to be less of a nuisance for administrators. Strictly user-caused errors are only reported in user log. Some errors are logged as info instead. * Sieve: Changed behavior of redirect in case of a duplicate message delivery or a mail loop. If a duplicate is detected the implicit keep is canceled, as though the redirect was successful. This prevents getting local deliveries. The original SMTP recipient is used when it is available to augment the entry in the LDA duplicate database. This way, duplicates are only detected when (initially) addressed to the same recipient. + Sieve vnd.dovecot.duplicate extension: added new features to the duplicate test, making it possible to manually compose the key value for duplicate checking. This extension is in the process of being standardized: https://tools.ietf.org/html/draft-bosch-sieve-duplicate-01 + Sieve date extension: generate warning when invalid date part is specified. - Sieve editheader extension: fixed crash occurring when addheader :last was used. - Sieve include extension: fixed missing error cleanup that caused a resource leak. - Sieve vacation extension: fixed determination of From: address for when sieve_vacation_dont_check_recipient is active. - Sieve tools: the -D option wasn't enabled and documented for all tools. - Sieve dict script storage: fixed potential segfault occurring when dict initialization fails. - ManageSieve: fixed bug in skipping of CRLF at end of AUTHENTICATE command. - ManageSieve: fixed handling of unknown commands pre-login. - Fixed compile on Mageia Linux. The release is available as follows: http://www.rename-it.nl/dovecot/2.1/dovecot-2.1-pigeonhole-0.3.4.tar.gz http://www.rename-it.nl/dovecot/2.1/dovecot-2.1-pigeonhole-0.3.4.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] password encryption
by Jim Pazarena 06 Apr '13

06 Apr '13

I have just come to the realization that password encryption using the crypt function in linux, ONLY USES THE FIRST 8 CHARS. I have written routines using crypt allowing 16+ chars, and find that anything past 8 is ignored. Wow. Is there a way around this that can be used in dovecot, as well as encryption routines for an email front end? (not system users). It's the integration with dovecot which is the most important.

[Dovecot] not showing subfolders on INBOX

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all, Apologies if a duplicate message. I initially sent the following from a non-subscribed email address (my usual address, but not the one that works when I'm having trouble with mail). First, I'm pretty sure I screwed up something with dovecot. The symptom appears in both thunderbird and mutt. I'm moving my server from a VPS to a dedicated server. *Both* are Arch Linux systems. Here's the dovecot -n output: # 2.1.15: /etc/dovecot/dovecot.conf # OS: Linux 3.8.4-1-ARCH x86_64 base_dir = /var/run/dovecot/ default_client_limit = 3000 default_process_limit = 1000 login_trusted_networks = 10.8.0.0/16 127.0.0.0/8 mail_location = maildir:~/Maildir mail_max_userip_connections = 30 passdb { args = failure_show_msg=yes driver = pam } service auth { unix_listener /var/spool/postfix/private/auth { mode = 0666 } } ssl_cert = </home/www/ssl/www.cybernude.org_publickey-apache.pem ssl_key = </home/www/ssl/www.cybernude.org_privatekey.pem userdb { driver = passwd } One detail, the kernel version, is different from what is indicated above. munich is the new system; atlanta is the old one: Linux munich.parts-unknown.org 3.8.4-1-ARCH #1 SMP PREEMPT Wed Mar 20 22:10:25 CET 2013 x86_64 GNU/Linux Linux atlanta.parts-unknown.org 3.6.10-1-ARCH #1 SMP PREEMPT Tue Dec 11 09:40:17 CET 2012 x86_64 GNU/Linux I literally copied this configuration, so it's the same on both systems. But on the new system, I'm not seeing subfolders in INBOX. I also copied my Maildir from the old system to the new system, so it should--I thought, anyway--be okay. What did I do wrong?

[Dovecot] v2.2.rc4 released
by Timo Sirainen 04 Apr '13

http://dovecot.org/releases/2.2/rc/dovecot-2.2.rc4.tar.gz http://dovecot.org/releases/2.2/rc/dovecot-2.2.rc4.tar.gz.sig A lot of small random fixes. Some last minute major cleanups/fixes to lib-http and lib-ssl-iostream error handling, which makes them much easier to debug if something goes wrong (so e.g. if https site has invalid certificate, the caller gets error message saying that, including the part of the cert that couldn't be validated). I don't have anything important left in my v2.2 TODO. It passes all my tests. So I'm hoping for v2.2.0 release any day now. + Added "doveadm replicator" commands - Larger changes to lib-http and lib-ssl-iostream error handling. The API caller can now get the exact error message as a string. - Various bugfixes to LDAP changes in rc3

[Dovecot] Outlook 2013 - mounting folders with XLIST
by Hajo Locke 04 Apr '13

04 Apr '13

Hello, i do some tests with dovecot 2.1.7 and activated a default special-use config. To get it work with outlook 2013, i also added XLIST to imap capability string. basically this is working. is somebody also using special-use folders successful with outlook 2013? In my understanding of special-use extension, every client should map its own local folders to corresponding folders on server. Real Name of folder on server should be irrelevant, if a folder "aaa" is marked as \Sent, then a Client should show this folder as "Sent" "Sent Items" or "Gesendete Objekte", just like local preferences. Outlook 2013 seems to work slightly different. Outlook 2013 seems to really use the marked folder on server regardless of local preferences. If i mark Drafts as \Drafts, outlook 2013 will use this for drafts even in german environment. Did somebody other notice this behaviour? Is it possible to adjust some settings in outlook 2013 fo fix this? Otherwise the serveradmin is forced to provide special-use folders per every single user and let them choose how his folders should be named? What experience did others make who use special-use folders in productive environment? Thanks, Hajo

[Dovecot] maildirsize problem
by mastertoilet＠netzero.net 04 Apr '13

04 Apr '13

i am currently using roundcube my webmail and configure using dovecot quota plugins. but it seems to not be updating the maildirsize when new mails comes.Deleting the maildirsize will recreate the files correctly.Is there any solutions to this problem with dovecot. Either you're not using dovecot-lda to deliver the mails, or you haven't configured quota plugin correctly for it. dovecot -n output and logs about a mail delivery would help. My configuration is using Centos 6.dovecot 2.1.1.and i have configure the quota plugin.but i am not sure what you mean by dovecot-lda.i just follow the guides on the internet and skim through dovecots documentation.i am using the local unix account for mail account not using virtual users.here is my configuration: [root@mail ~]# dovecot -n # 2.1.1: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-279.el6.x86_64 x86_64 CentOS release 6.3 (Final) base_dir = /var/run/dovecot/ mail_debug = yes mail_location = maildir:~/Maildir mail_plugins = " quota" maildir_broken_filename_sizes = yes mbox_write_locks = fcntl 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 } plugin { quota = maildir:User quota quota_rule = *:storage=1G quota_rule2 = Trash:storage=+100M } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } } ssl = required ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { driver = passwd } protocol imap { imap_id_log = * imap_idle_notify_interval = 2 mins mail_plugins = " quota imap_quota" } protocol pop3 { mail_plugins = " quota imap_quota" } i am still not sure why maildirsize is not updating.thanks ____________________________________________________________ How to Sleep Like a Rock Obey this one natural trick to fall asleep and stay asleep all night. http://thirdpartyoffers.netzero.net/TGL3231/515ce5588c8f765586e9dst01duc

[Dovecot] sieve-filter ignoring separator
by Isak Rubin 03 Apr '13

03 Apr '13

It seems like running sieve-filter from the console ignores the separator setting, thus not letting me filter into folder names containing dots. Normal delivery using lda handles it just fine, but not when using the sieve-filter command. Character not allowed in mailbox name: '.' Is there anyway to override this or is patching and recompiling the source my only option? # dovecot --version 2.1.9 /Isak

[Dovecot] Sieve vacation issue - Dovecot + Postfix + LDA
by Ivan Bogdanovic 03 Apr '13

03 Apr '13

Hi to all, I have an issue with Dovecot Sieve on sending vacation message... Actually Sieve is working and I can use all the filters but just vacation is causing a problem and only in specific case... I have Dovecot + Postfix + LDA running on Ubuntu 11 without MySql database for users but I'm using virtusertable instead. The problem is when linux user ( mail user ) is different from mail allias in virtusertable... Example: ivan(a)domain.com > ivan1 ( from virtusertable ). When alias and user are the same sieve vacation works just fine but when it's not the sieve script collects the user(ivan1)(a)domain.com in from instead ivan(a)domain.com and this is when mail log shows like "discarded message because of implicitily no known envelope in message header etc... Is there a way to adjust sieve to pickup the recipient address from mail header or whatever and not to collect the user...? I was trying to play with postfix master.cf using dovecot-lda switches -f ${sender} -a (or -d ) ${recipient} but without success... Did anyone had this kind of problem? I would really appreciate some hints on fixing this issue... Thanks, Ivan

[Dovecot] Separate log file for Sieve
by Ewald Dieterich 03 Apr '13

03 Apr '13

I use log_path = /var/log/dovecot/error.log info_log_path = /var/log/dovecot/info.log debug_log_path = /var/log/dovecot/debug.log to log to different files. Since I don't consider Sieve errors as severe as "real" Dovecot errors I would like to keep them away from the error log. Is it possible to configure a separate log file for Sieve?
