Hello Timo, I think the following commit makes problems: http://hg.dovecot.org/dovecot-2.2/rev/68a8b650578e # Doesn't work A01 LIST "" ~/Mail/Gesendet # OK with quoted mailbox A02 LIST "" "~/Mail/Gesendet" Details: imap * PREAUTH [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS THREAD=ORDEREDSUBJECT MULTIAPPEND URL-PARTIAL CATENATE UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS SPECIAL-USE BINARY MOVE] Logged in as user A01 LIST "" ~/Mail/Gesendet A01 BAD Error in IMAP command LIST: literal8 not allowed here A02 LIST "" "~/Mail/Gesendet" * LIST (\NoInferiors \UnMarked) "/" ~/Mail/Gesendet A02 OK List completed.

[Dovecot] BUG report: doveadm HEADER <field> <pattern> when concatenating with another Search key
by megodin＠inboxalias.com 07 May '14

07 May '14

Hey there, I'm pretty sure I've found a bug with doveadm when concatenating with another search key. While doveadm HEADER <field pattern> works fine when not using additional search keys, it doesn't work properly when concatenating with other serarch keys - it then simply seems to ignore the additional HEADER <field pattern> search key. It's reproduceable, also with different user accounts on 2 different productive systems. Testing it on latest dovecot-ee 2.2.9.2 and 2.2.5.5. I think it's best explained with showing some examples: doveadm search -u exampleuser SUBJECT Silvester (outputs correctly 10 matches) 5a09f50926daef51b50e000025ab05f8 1106 5a09f50926daef51b50e000025ab05f8 1107 5a09f50926daef51b50e000025ab05f8 1579 5a09f50926daef51b50e000025ab05f8 4092 5a09f50926daef51b50e000025ab05f8 5330 5a09f50926daef51b50e000025ab05f8 9773 5a09f50926daef51b50e000025ab05f8 11460 5a09f50926daef51b50e000025ab05f8 12718 5a09f50926daef51b50e000025ab05f8 15653 5a09f50926daef51b50e000025ab05f8 15697 doveadm search -u exampleuser SUBJECT Silvester HEADER Return-Path someuser(a)example.com (gives exactly the same output - but this is WRONG, as the given Subject AND Return-Path is really only found in 1 Message - uid 15697) 5a09f50926daef51b50e000025ab05f8 1106 5a09f50926daef51b50e000025ab05f8 1107 5a09f50926daef51b50e000025ab05f8 1579 5a09f50926daef51b50e000025ab05f8 4092 5a09f50926daef51b50e000025ab05f8 5330 5a09f50926daef51b50e000025ab05f8 9773 5a09f50926daef51b50e000025ab05f8 11460 5a09f50926daef51b50e000025ab05f8 12718 5a09f50926daef51b50e000025ab05f8 15653 5a09f50926daef51b50e000025ab05f8 15697 doveadm search -u exampleuser HEADER Return-Path someuser(a)example.com (showing that Return-Path as standalone search key is working fine - note that message uid 15697 with subject "Silvester" is also found of course.

[Dovecot] New global ACL mailbox pattern feature in HG
by Thomas Leuxner 07 May '14

07 May '14

Hi, I played around with changeset 9376bf098692 a bit. Right now I'm unsure how to describe a namespace using this feature. Using something like 'Public/*" doesn't seem to work while 'Public*" does, but would also potentially alter non-related mailboxes elsewhere: $ cat global-acl INBOX owner lrwstiekxap Public* group=PublicMailboxAdmins lrwsik Regards Thomas

[Dovecot] SSL/TLS handshake stays forever without timeout
by morrison 07 May '14

07 May '14

Hi, I am a system admin and I am evaluating using dovecot as our email server. In my test, I found that if I telneted to 993 port and did not do anything or I telneted to 143 port, sent starttls command and then did not do anything, the connection stayed forever without timeout. This will make our mail server vulnerable to DOS attack. I dig into dovecot Wiki and did not find any solution. This seems to me that dovecot does not handle SSL/TLS handshake timeout. I am wondering if this is a known issue and will be fixed in near future. Thanks,

[Dovecot] output of doveconf in conflict with order of settings in conf.d/*-*.conf files

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I wanted to enable stats, so I added the settings from http://wiki2.dovecot.org/Statistics into conf.d/99-stats.conf: mail_plugins = $mail_plugins stats protocol imap { mail_plugins = $mail_plugins imap_stats } plugin { # how often to session statistics stats_refresh = 30 secs # track per-IMAP command statistics stats_track_cmds = yes } reloaded dovecot, see output of doveconf -n below, but I got the error: imap: Error: Can't load plugin imap_stats_plugin: Plugin stats must be loaded also (you must set: mail_plugins=$mail_plugins stats) If I move the line "mail_plugins = $mail_plugins stats" from 99-stats.conf into 15-stats.conf, the output of doveconf -n looks the same, but the stats is working.

[Dovecot] ID command and dovecot
by Jernej Porenta 02 May '14

02 May '14

Heya, we are seeing some strange issues with IMAP ID command using latest Roundcube builds on dovecot 2.2.10 responding "Input buffer full, aborting". Roundcube webmail connects to IMAP server and issues ID command first with some long arguments to ID command, however shorter than 1024 octets, which are specified in RFC2971 for ID IMAP extension. The situation is easily reproducible (see http://pastebin.com/q4HX4wqb) # telnet hostname 143 * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE AUTH=PLAIN AUTH=LOGIN] Server ready. . ID ("name" "Roundcube" "version" "1.0-git" "php" "5.3.3" "os" "Linux" "command" "<$long_less_than_1024_octets_string>") * BYE Input buffer full, aborting However, this problem does not occur when user is already logged in. RFC2971 is saying "Field strings MUST NOT be longer than 30 octets. Value strings MUST NOT be longer than 1024 octets. Implementations MUST NOT send more than 30 field-value pairs." IMHO, dovecot is handling ID command before successful login successfully only if the length of the whole command is less than 1024 octets (exactly 861 octets is working fine, over that "Input buffer full" occurs). I tried finding the reference in the source code, however I am unable to find where this limit actually occurs (maybe IMAP_ARG_STRING imap_arg->type?) thank you in advance, regards, Jernej

[Dovecot] nfs flush/fsync config settings problem
by Troton_admin 03 Apr '14

03 Apr '14

Hi, I need to place a maildir storage on a NFS filesystem, so I set up the config like this: mmap_disable = yes mail_nfs_storage = yes mail_nfs_index = yes mail_fsync = always lock_method = dotlock (also tried fcntl - local lockd is running, no success, now using dotlock, to be sure while debugging) The problem is that Dovecot (2.2.9/2.2.10 - the relevant code in mail-index.c is the same) logs a fatal error and quits the session (no daemon crash/coredump).

Any ideas, what could possibly be wrong ? Is it a feature or a bug ? Thanks for your help. Regards, Troton

[Dovecot] Is replication broken?
by IT geek 31 03 Apr '14

03 Apr '14

Hi, Apologies for this being my 248th post about replication... The current error I'm getting is: Jan 30 12:10:54 Server1 dovecot: dsync-local(MailUser1): Error: dsync( Server2.test.com) read() failed: read((fd)) failed: Connection reset by peer Subsequent errors are: Jan 30 12:15:47 Server1 dovecot: dsync-local(MailUser1): Error: read( Server2.test.com) failed: EOF The above error is seen on Server1, after the initial sync completes of the first mailbox (Sent folder to be precise). Does anyone have an ideas as to what might be causing it? These are brand new rebuilds, running the latest build - I just can't seem to get this working. Bug maybe? Configs are as follows: Server1: # 2.2.10: /usr/pkg/etc/dovecot/dovecot.conf # OS: NetBSD 5.2 cobalt auth_mechanisms = plain login doveadm_password = secret doveadm_port = 12345 first_valid_uid = 1003 last_valid_uid = 1020 listen = 192.168.1.1 login_greeting = test.com mail_location = mbox:~/mail:INBOX=/var/mail/%u mail_plugins = " notify replication" passdb { driver = passwd } plugin { mail_replica = tcp:Server2.test.com } protocols = imap service aggregator { fifo_listener replication-notify-fifo { mode = 0666 } unix_listener replication-notify { mode = 0600 } } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } user = root } service imap-login { inet_listener imap { port = 0 } } service replicator { process_min_avail = 1 unix_listener replicator-doveadm { mode = 0600 } } ssl_cert = </etc/openssl/certs/Server1.test.crt ssl_key = </etc/openssl/private/Server1.test.key userdb { driver = passwd } protocol lda { postmaster_address = postmaster(a)test.com } ServerB: # 2.2.10: /usr/pkg/etc/dovecot/dovecot.conf # OS: NetBSD 5.1 cobalt auth_mechanisms = plain login doveadm_password = secret doveadm_port = 12345 listen = 192.168.1.2 login_greeting = test.com mail_location = mbox:~/mail:INBOX=/var/mail/%u passdb { driver = passwd } protocols = imap service aggregator { fifo_listener replication-notify-fifo { mode = 0666 } unix_listener replication-notify { mode = 0600 } } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } user = root } service doveadm { inet_listener { port = 12345 } } service imap-login { inet_listener imap { port = 0 } } service replicator { process_min_avail = 1 unix_listener replicator-doveadm { mode = 0600 } } ssl_cert = </etc/openssl/certs/Server2.test.com.crt ssl_key = </etc/openssl/private/Server2.test.com.key userdb { driver = passwd } protocol lda { postmaster_address = postmaster(a)test.com }

[Dovecot] possible quota bug ?
by fernando.figaro＠uol.com.br 31 Mar '14

31 Mar '14

Hi, I'm using dovecot 2.2.5 with quota (maildir backend), zlib and expunge plugins. When I list maildirsize file, I get: 1073741824S 17952 16 If I receive a new message (example: 1204 bytes compressed and 2524 bytes plain text), the quota file is write correctly (2524 1 entry). When I move the message to trash folder (or between user custom folders) the file have wrong entries: 1073741824S 17952 16 2524 1 1204 1 (this is the size of the compressed message) -2524 -1 I coudn't find any relation with the config settings causing this problem and checked the changelog since 2.2.5. Had someone had this same problem? Thanks, Fernando

[Dovecot] dsync in a cronjob to replace offlineimap
by Guilhem Moulin 24 Mar '14

24 Mar '14

Hi list, Replacing offlineimap with dsync for IMAP-to-IMAP synchronization (using dovecot 2.1.7) is working great, but now that I upgraded to 2.2.9 I'd like to take advantage of the incremental replication [1]. I don't think having a separate replicator process & notifications suits my configuration, as I want to sync my server with my laptop which is not always on or might be behind a firewall. After reading ‘replication/replicator/dsync-client.c’ I was thinking of writing a small wrapper around dsync performing a daily full replication and updating the state otherwise. The following works great in a cronjob doveadm sync -l30 imap.example.org but when I try to get the current state doveadm sync -l30 -fs '' imap.example.org >~/mail/dsync.state and later use incremental replication state=$(< ~/mail/dsync.state) doveadm sync -l30 -s "$state" imap.example.org >~/mail/dsync.state the state seems to somehow quickly become "stale" and messages stop being retrieved from the server. I understand that dsync's incremental replication is mostly intended to be used by the replicator process, but I'm wondering whether it's also possible to use it manually ;-) If so, how to keep a sane state? Thanks, cheers, -- Guilhem. [1] http://wiki2.dovecot.org/Replication
