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

15 May '13

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

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

15 May '13

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

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

14 May '13

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

[Dovecot] ot: mirroring/archiving to a Mac?
by voytek＠sbt.net.au 14 May '13

14 May '13

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

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

12 May '13

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

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

10 May '13

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

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

09 May '13

After upgrading my IMAP server to the new debian stable, and upgrading dovecot from 1.x to 2.1.7 in the process, dovecot no longer logs anything to /var/log/mail.*. The last entries there are from before the upgrade, and no starts or error messages or failed login attempts, since then, have been logged. Does anyone know what might cause this? "doveconf -n" doesn't mention any of the log settings. Maybe the log settings aren't picked up? What could be done to make sure they are picked up? Here's the content of the /etc/dovecot/conf.d/10-logging.conf file: ## ## Log destination. ## # Log file to use for error messages. "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
by Tobi 09 May '13

09 May '13

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

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

09 May '13

When I upgraded my debian-based imap server from squeeze to wheezy yesterday, SSL stopped working. I am using a http://cacert.org signed server sertificate, and I am reusing the certificates that were used on the 1.x dovecot of debian squeeze. My three MUAs that worked against the previous 1.x dovecot with the same certificate, now fails in various ways. Any hints and guesses as to how to debug this further will be highly appreciated. Even more appreciated will be a pin point of the issue. :-) Here are the error messages from the MUAs: - Opera 12.15 on Windows 7 just reports: "The connection with the IMAP server was unexpectedly interrupted." - Emacs24(w/linked-in gnutls)/Ma Gnus 0.8 (Gnus git HEAD) on Windows 7 says "imap.mydomain.com certificate could not be verified." - Emacs23/Ma Gnus 0.8 (also Gnus git HEAD) on debian testing (with Emacs23 gnutls-cli is run in a subprocess), says: "Opening connection to imap.mydomain.com via tls...

Opening TLS connection 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?

[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

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.

[Dovecot] URLAUTH assertion failures in 2.2.1

Testing URLAUTH in dovecot-2.2.1 plus Timo's recent CATENATE and URLAUTH fixes eventually trips some assertions. No simple sequence of commands always hits these; they appear to be timing-dependent.

Hallo zusammen, über den Policy Service von Dovecot zum Abfragen der User Quotas wurde ja schon diskutiert - auch gibt es eine gute Anleitung zum Einrichten, nur leider bekomme ich den Policy Server nicht korrekt konfiguriert.

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. Exception Type: EXC_BAD_ACCESS (SIGSEGV) Exception Codes: KERN_INVALID_ADDRESS at 0x0000000000001059 0 libdovecot-storage.0.dylib 0x000000010b06a383 imap_msgpart_url_free + 17 1 imap 0x000000010afc71cc imap_urlauth_fetch_local + 770 2 imap 0x000000010afc6dcf imap_urlauth_fetch_url + 439 3 imap 0x000000010afbb489 cmd_urlfetch + 580 4 imap 0x000000010afbdf4d command_exec + 55 5 imap 0x000000010afbdabb client_command_input + 34 6 imap 0x000000010afbdc7c client_command_input + 483 7 imap 0x000000010afbd351 client_handle_input + 239 8 imap 0x000000010afbc613 client_input + 119 9 libdovecot.0.dylib 0x000000010b111c74 io_loop_call_io + 46 10 libdovecot.0.dylib 0x000000010b112c85 io_loop_handler_run + 214 11 libdovecot.0.dylib 0x000000010b111e1f io_loop_run + 77 12 libdovecot.0.dylib 0x000000010b0d10c6 master_service_run + 24 13 imap 0x000000010afc5aba main + 1010 14 libdyld.dylib 0x00007fff89e5f7bd start + 1 Apr 29 20:00:31 imap(pid 82429 user mja): Debug: Fetching local URLAUTH imap://mja@duck.example.com/INBOX;uidvalidity=1366726248/;uid=19;urlauth=submit+mja:internal:012c9c6a3d74db6509e4a3802a0f5edf64546608b8 Apr 29 20:00:31 imap(pid 82429 user mja): Debug: Failed to fetch URLAUTH "imap://mja@duck.example.com/INBOX;uidvalidity=1366726248/;uid=19;urlauth=submit+mja:internal:012c9c6a3d74db6509e4a3802a0f5edf64546608b8": No 'submit+mja' access allowed for user mja Apr 29 20:00:31 imap(pid 82429 user mja): Fatal: master: service(imap): child 82429 killed with signal 11 (core dumps disabled)

[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

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. Refer to server log for more information. [2013-05-02 13:54:40] May 02 13:57:42 pop3(user(a)domain.com): Info: Mailbox init failed top=0/0, retr=0/0, del=0/0, size=0 I really appreciate any suggestion!

[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

Im trying to convert my dovecot-lda setup to use LMTP for better security. My setup is postfix + dovecot + mysql with virtual users. Im setting up dovecot 2.2.1 w/postfix 2.10.0 Im still learning dovecot so Im not totally sure where Im going wrong. Can someone point out why Im getting permission problems? Im also concerned with server security, so if you notice anything that should be better, please point that out. I am the only user on this Linux box. Thank you! ls -l /opt/imapdata/j/jeff/INBOX total 8 drwxr-xr-x 2 vmail vmail 4096 Apr 27 14:21 ./ drwxr-xr-x 3 vmail vmail 4096 Apr 27 14:21 ../ Dovecot is running with the following users: root 20847 0.0 0.0 15572 1108 ?
