[Dovecot] Released Pigeonhole v0.4.3 for Dovecot v2.2.13.
by Stephan Bosch 12 May '14

12 May '14

Hello Dovecot users, Now that Dovecot v2.2.13 is released, I can release a new Pigeonhole. Due to changes in Dovecot, this Pigeonhole release will not compile cleanly against older Dovecot releases. This release is mainly about bugfixes. One notable addition is that I have updated the "vnd.dovecot.duplicate" extension to the new IETF draft "duplicate" extension. Changelog v0.4.3: * Editheader extension: Made control characters allowed for editheader, except NUL. Before, this would cause a runtime error. + Upgraded Dovecot-specific Sieve "vnd.dovecot.duplicate" extension to match the new draft "duplicate" extension. - Fixed sieve_result_global_log_error to log only as i_info in administrator log (syslog) if executed from multiscript context. - Sieve redirect extension: Adjusted loop detection to show leniency to resent messages. - Sieve include extension: Fixed problem with handling of duplicate includes with different parameters :once or :optional. - Sieve spamtest/virustest extensions: Tests were erroneously performed against the original message. When used together with extprograms filter to add the spam headers, the changes were not being used by the spamtest and virustest extensions. - Deprecated Sieve notify extension: Fixed segfault problems in message string substitution. - ManageSieve: Fixed active link verification to handle redundant path slashes correctly. - Sieve vacation extension: - Fixed interaction of sieve_vacation_dont_check_recipient with sieve_vacation_send_from_recipient setting. - Fixed log message for discarded response. - Sieve extprograms plugin: - Forgot to disable the alarm() timeouts set for script execution. - Fixed fd leak and handling of output shutdown. - Fixed 'Bad filedescriptor' error occurring when disconnecting script client. - Made sure that programs are never forked with root privileges. The release is available as follows: http://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.3.tar… http://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.3.tar… 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] 2.2.12: Panic: file mail-index.c: line 380 (mail_index_keywords_unref): assertion failed: (keywords->refcount > 0)
by Leho Kraav 12 May '14

I upgraded 2.1 -> 2.2 something like a week ago because I needed INDEXPVT. Not sure if this crash started immediately or not, noticed it today looking at journalctl. Backtrace http://bpaste.net/raw/181944/ and pasted below. This seems to crash on every IMAP connection made, so any ideas for a possible client-level workaround are quite welcome until dovecot code improves here. root@server ~ $ dovecot -n # 2.2.12:

[Dovecot] IMAP disconnect before greeting / banner
by Benoit Panizzon 12 May '14

12 May '14

Hello We have a server on which we run multiple instances of dovecot. Each instance serving a domain and binding to a specific IP. The whole thing on three servers using the proxy ability and replication of dovecot. Now one domain has more users and we start seeing very strange behaviour. As soon as about 45 users have connected to the imap service ip of that instance, the server accepts the connections and then disconnects without showing the IMAP banner. This happens on all of our three servers and only for that specific domain (which has most connections). While this occurs, there is no problem with the other instances for other domains on the same physical machine. So the database backend etc. are not the issue. While this occurs, there is no hint of what goes wrong in the logfiles. I did even set mail_debug=yes but that still does not produce any output of why clients get disconnected prior to the server displaying the banner. Any hints on where I could start looking for the error, or get more debug output as with mail_debug=yes ? -Benoit-

[Dovecot] ManageSieve OOM with Huge Folders
by Fabian Peter 12 May '14

12 May '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Hi all, we're experiencing "Out of Memory" Problems caused by Sieve-Filters delivering mail to huge IMAP folders. From the logs, I'm beginning to think the problem is that the sieve/lmtp process loads the "dovecot.index.cache" file apparently twice into memory to do something with it. We've set our memory limit per process to 256MB - the cache file of the folders we're having issues with is exactly 128MB. Mails coming in that should be filtered to these folders are being denied, an error is being logged. Apparently, there would be two easy solutions to this: increasing memory OR decreasing folder size. Both are not possible. Increasing memory just means we will have this issue again in some weeks. Deacreasing mailbox size isn't possible since the folders contain archived system mails from our backend software which need to be kept for a while. Currently, we're creating a new folder each time we reach this limit, but that isn't exactly the best way to go for the future. In the end, the folders are for archiving purposes and therefore should not be managed at all since all this is automated. I hope there's some obvious switch I've just not seen in the config. I actually can't imagine that this is default or wanted behaviour since there must be people with large inboxes and sieve filters that either also have this problem or don't have it since they fixed it. The problem clearly is reproducable. Each time the cache file hits 128MB - which happens at around 200k mails in the folder - (with our current setting of 256MB memory limit per process), things go down and our mailqueues reach 10k undelivered mails within a few hours.

[Dovecot] v2.2.13.rc1 vs. Pigeonhole
by Tamsy 12 May '14

12 May '14

Server: Ubuntu 10.04 LTS 32bit There seems to be an incompatibility when compiling Pigeonhole against Dovecot v2.2.13.rc1. # make check with Pigeonhole throws up the following error message: <snip> Test case: ./tests/extensions/editheader/addheader.svtest: 1: Test 'Addheader - first' SUCCEEDED 2: Test 'Addheader - last' SUCCEEDED 3: Test 'Addheader - framed' SUCCEEDED 4: Test 'Addheader - folded' SUCCEEDED 5: Test 'Addheader - newlines' FAILED: wrong first header content in redirected mail 6: Test 'Addheader - implicit keep' SUCCEEDED 7: Test 'Addheader - UTF 8' SUCCEEDED 8: Test 'Addheader - devious characters' SUCCEEDED FAIL: 1 of 8 tests failed. I tried this with the latest Pigeonhole from Mercurial: - dovecot-2-2-pigeonhole-3b6917a4807c and also with the older: - dovecot-2-2-pigeonhole-e111a2393a92 Both versions are quitting during "make check" with the same error when compiling against dovecot-2.2.13.rc1. Compiling those versions against dovecot-2.2.12 is going without errors though. Cheers, Tamsy

[Dovecot] message-decoder bug for attachments with charset=binary attribute in content-type?
by Robert Wolf 12 May '14

12 May '14

Hello, I have configure dovecot with solr and I wanted to let solr index content of attachments. For testing I have used biabam command line tool to generate emails with attachments. I have found that dovecot with fts_decoder incorrectly decodes these attachments from biabam and therefore pdftotext has reported corrupted PDF. The problem is that biabam generates header with charset=binary and dovecot message decoder tries to process it as UTF8 or non-UTF8 data. ============================================================ --biabam.ZxWVLybiabam.ZxWVLy Content-Type: application/pdf; charset=binary Content-Disposition: attachment; filename="bacula-jobs.pdf" Content-Transfer-Encoding: base64 JVBERi0xLjQKJcfsj6IKNSAwIG9iago8PC9MZW5ndGggNiAwIFIvRmlsdGVy IC9GbGF0ZURlY29kZT4+CnN0cmVhbQp4nF2PT0+EMBDF7/0U7yYYWdqFXdbe 1vgnMXpQezMeClSoQNltweh+egvLyczhN3kz703mCLpioFMtLDoSv2aoHKGo ..... ============================================================ This PDF begins orginal with ============================================================ 0000000: 2550 4446 2d31 2e34 0a25 c7ec 8fa2 0a35 %PDF-1.4.%.....5 0000010: 2030 206f 626a 0a3c 3c2f 4c65 6e67 7468 0 obj.<</Length 0000020: 2036 2030 2052 2f46 696c 7465 7220 2f46 6 0 R/Filter /F 0000030: 6c61 7465 4465 636f 6465 3e3e 0a73 7472 lateDecode>>.str ============================================================ But the dovecot pass following data to fts_decoder script: ============================================================ 0000000: 2550 4446 2d31 2e34 0a25 c3a4 c3bc c3b6 %PDF-1.4.%...... 0000010: c39f 0a32 2030 206f 626a 0a3c 3c2f 4c65 ...2 0 obj.<</Le 0000020: 6e67 7468 2033 2030 2052 2f46 696c 7465 ngth 3 0 R/Filte 0000030: 722f 466c 6174 6544 6563 6f64 653e 3e0a r/FlateDecode>>. ============================================================ As you can see binary data are mangled.

Original code: ============================================================ 241: ctx->binary_input = ctx->content_charset == NULL && 242: (ctx->flags & MESSAGE_DECODER_FLAG_RETURN_BINARY) != 0 && 243: (part->flags & (MESSAGE_PART_FLAG_TEXT | 244: MESSAGE_PART_FLAG_MESSAGE_RFC822)) == 0; ============================================================ My update: ============================================================ 241 ctx->binary_input = ((ctx->content_charset != NULL) && (strcasecmp(ctx->content_charset, "binary") == 0)) || (ctx->content_charset == NULL && 242 (ctx->flags & MESSAGE_DECODER_FLAG_RETURN_BINARY) != 0 && 243 (part->flags & (MESSAGE_PART_FLAG_TEXT | 244 MESSAGE_PART_FLAG_MESSAGE_RFC822)) == 0); ============================================================ This will set ctx->binary_input for the attachment with charset set to "binary". I don't know if this is correct update, but the searching works with this update for biabam binary attachments too. Could you please verify this problem and maybe update the code? Thank you very much. # dovecot --version 2.1.7 Config: plugin { fts = solr fts_solr = url=http://localhost:8080/solr/ fts_decoder = decode2text } service decode2text { executable = script /etc/dovecot/scripts/decode2text.sh user = dovecot unix_listener decode2text { mode = 0666 } } Regards, Robert Wolf.

[Dovecot] Segfault with passwd as a second userdb at auth_fields_rollback
by Jan Kończak 11 May '14

11 May '14

Hello, I've been trying to set up dovecot to support passwd-file + passwd/PAM auth. I made an unusual config (passwd-file as userdb failed to work for me), which uses static as userdb: =============== passdb { driver = passwd-file args = username_format=%u scheme=CRYPT /etc/dovecot/users } userdb { driver = static default_fields = uid=vmail gid=vmail home=/var/spool/mail/%d/%n } passdb { driver = pam } userdb { driver = passwd } =============== While passwd-file+static worked well, passwd/PAM caused trouble: $ doveadm user xxx doveadm(root): Error: userdb lookup(xxx): Disconnected unexpectedly field value If passwd-file had the user, check went fine; otherwise it segfaulted. The crash has been accompanied by a syslog message: kernel: auth[9788]: segfault at 18 ip 0000000000416391 sp 00007fffd11a3d90 error 4 in auth[400000+44000] Translating address lead me to: 0000000000416390 <auth_fields_rollback>: 416390: 53 push %rbx 416391: 48 83 7f 18 00 cmpq $0x0,0x18(%rdi) I was using packages from http://packages.atrpms.net/dist/el6/dovecot/ To be precise, dovecot-2.2.10-1_14.el6.x86_64.rpm I tampered with the src.rpm, upgraded spec&sources to match 2.2.12. It didn't help, so I tries to "workaround" this. The bug has gone when in src/auth/auth-fields.c:210 I added check if the field ptr is not null. As it's a userdb query, it seems that for some reason (static?) in src/auth/auth-request.c:1058 the function auth_fields_rollback is called with null request->userdb_reply Now it works fine: $ doveadm user xxx field value uid 1000 gid 100 home /home/xxx mail maildir:~/.maildir system_groups_user xxx $ doveadm user jkonczak@ast... field value uid 103 gid 103 home /var/spool/mail/ast.../jkonczak mail maildir:~/.maildir So now virtual users get vmail uid/gid, system users get their uid/gid, home is fine etc. Below I attach the patch + full config.

[Dovecot] ECDSA certificate support
by SIW 11 May '14

11 May '14

Does the latest version of Dovecot support ECDSA certificates? I had a look in: http://wiki2.dovecot.org/SSL but it didn't answer my question. Can someone please help or point me in the right direction? I'd also like to know if I can run an RSA cert AND an ECDSA certificate at the same time in Dovecot (like you can in Postfix). Many thanks.

[Dovecot] Only part of sieve script works
by Sebastian Schlingmann 10 May '14

10 May '14

Hi, I am using Dovecot 2.2.11 with Pigeonhole on Arch Linux. I have a partly working sieve script (pasted to the end of this mail) which sorts mail into various imap folders. The first, third and fourth if blocks work just fine. The second and fifth block do not sort any mails. However, if I apply the script with sieve-test to mails the second and fifth block seem to work. How is the manual check with sieve-test different from the sieve filtering during mail delivery? I am thankful for any hints. Sebastian this is the sieve script I am talking about require "fileinto"; # Musik wegsortieren if anyof ( header :comparator "i;ascii-casemap" :contains "Subject" "Mixing.DJ", header :comparator "i;ascii-casemap" :contains "Subject" "John B", header :comparator "i;ascii-casemap" :contains "Subject" "FLOSS Weekly", header :comparator "i;ascii-casemap" :contains "Subject" "BrainStuff", header :comparator "i;ascii-casemap" :contains "Subject" "Nerdy Show", header :comparator "i;ascii-casemap" :contains "Subject" ["My Brother", " My Brother And Me"], header :comparator "i;ascii-casemap" :contains "Subject" "MoJoMenace", header :comparator "i;ascii-casemap" :contains "Subject" "GWJ Conference Call", header :comparator "i;ascii-casemap" :contains "Subject" "Welcome to Night Vale", header :comparator "i;ascii-casemap" :contains "Subject" "International Waters" ) { fileinto "Feeds.music"; stop; } # Youtube wegsortieren if address :all :comparator "i;ascii-casemap" :contains "From" "noreply(a)youtube.com" { fileinto "Feeds.Youtube"; stop; } # Awesomer wegsortieren if header :comparator "i;octet" :contains "Subject" "[The Awesomer]" { fileinto "Feeds.Awesomer"; stop; } # Feeds sortieren if address :all :comparator "i;octet" :contains "From" "sebi+feedmailer(a)mighty.selfhost.bz" { fileinto "Feeds"; stop; } # AIStA wegsortieren if header :comparator "i;ascii-casemap" :contains "Received" "webmail.awista.net" { fileinto "AIStA"; stop; }

[Dovecot] Denial of Service attacks against Dovecot v1.1+
by Timo Sirainen 10 May '14

10 May '14

There's an upper limit to how many IMAP/POP3 connections can exist that haven't logged in (and separate limits for post-login). Normally when this limit is reached, the oldest connection gets disconnected. There is of course some potential to try to DoS Dovecot by doing a lot of IMAP/POP3 connections, but because the oldest connection always gets destroyed this requires quite a lot of activity from the attacker. This "destroy oldest connection" however hasn't been working in v1.1+ releases for connections that have started SSL/TLS handshake, but haven't finished it. So an attacker could just do a bunch of TCP connections to port 993 and leave them hanging around and Dovecot would pretty quickly reach the upper limit without being able to disconnect any of the oldest connections. Here are patches to fix this: http://hg.dovecot.org/dovecot-2.2/rev/41622541a7a3 http://hg.dovecot.org/dovecot-2.1/rev/b7ac23b4d339 http://hg.dovecot.org/dovecot-2.0/rev/48f90e7e92dc http://hg.dovecot.org/dovecot-1.2/rev/8ba4253adc9b http://hg.dovecot.org/dovecot-1.1/rev/fe0e6550585c The fix will be in v2.2.13. Maybe also in v2.1.18 if I decide to release it. For older releases you need to patch it yourself. For people who are using dovecot-ee releases the fix is also in v2.2.12.12 and v2.1.7.7 releases.

[Dovecot] Strange behavior on with "listescape" and "lda_mailbox_autocreate" - double entries
by Patrick De Zordo 09 May '14

09 May '14

Hello Guys, we are using Dovecot since years; all working flawless but one strange behavior: Let me explain.. - we have enabled the "listescape" plugin in "15-lda.conf", "10-mail.conf" and "20-imap.conf". - we use the following default namespace in "10-mail.conf": --------------- 10-mail.conf ----------------------------------------- namespace { type = private prefix = separator = / inbox = yes subscriptions = yes } ---------------------------------------------------------------------------------------- - we use a sieve script that automatically generates folders in the following form (example): ---------------------------------------------------------------------------------------- ".INBOX.2014.05.patrick.incoming" for user "patrick(a)xx.com" ".INBOX.2014.05.patrick.outgoing" for user "patrick(a)xx.com" ".INBOX.2014.05.p\2edezordo.incoming" for user "p.dezordo(a)xx.com" ---------------------------------------------------------------------------------------- This is ok, but the automatically generated "subscriptions"-file of the user contains double lines (the second line is something strange?!); the second one should not be created, its totally wrong..! --------------- subscriptions ----------------------------------------- Trash Sent INBOX.2014.05.patrick.incoming INBOX.2014.05.patrick.outgoing INBOX.2014.05.p\2edezordo.incoming INBOX\2e2014\2e05\2ep\5c2edezordo\2eincoming <----- this line!?!?!? ---------------------------------------------------------------------------------------- Have you any ideas whats going on? Could this be a bug, or misconfiguration? Thanks in advance!! Greeting from Italy! Patrick.

I use MySQL to store my virtual users passwords and I am running the latest version of Dovecot. What I need to do is have one particular user have ONLY access to their email via Roundcube (webmail) and no IMAP/SMTP access. Therefore, how do I disable IMAP/SMTP access for just one user?

[Dovecot] imapc with Outlook.com transfers max 22-23 messages per mailbox!?
by Nicholas Riley 08 May '14

08 May '14

Hi, I'm trying to migrate a user from Outlook.com IMAP to Dovecot. I'm using a setup similar to that on http://wiki2.dovecot.org/Migration/Dsync: imapc_host = imap-mail.outlook.com imapc_user = [...](a)hotmail.com imapc_password = [...] imapc_features = rfc822.size fetch-headers mail_prefetch_count = 20 imapc_port = 993 imapc_ssl = imaps imapc_ssl_verify = yes ssl_client_ca_dir = /etc/ssl # this needs fixing on the wiki page Here's how I sync a single mailbox, which should have a few hundred messages in it: % doveadm -D -v -c [...] sync -1 -R -u [...] -m Avalon imapc: Output is at http://sabi.net/temp/sync.txt But every mailbox contains at most 22-23 messages. % for i in Maildir/**/cur; do echo $i $(ls -1 $i | wc -l) done Maildir/Alaska/cur 23 Maildir/Avalon/cur 22 Maildir/Christine Scott/cur 22 Maildir/Cornell/cur 22 Maildir/Coupons/cur 10 Maildir/Deleted/cur 22 [...] I was using 2.2.9 but I also tried with the dovecot-2.2 hg tip and did not see any difference. Is there a rawlog equivalent for imapc? I'm hoping that there is a simple protocol usage change that could let me get entire mailboxes. -- Nicholas Riley <njriley(a)illinois.edu>

[Dovecot] segfault with shared namespace version > 2.1.16

We're currently running 2.1.16. I've been wanting to update to a 2.2.X version, but have been running into problems, even with the latest (2.2.12).

[Dovecot] Dsync via dovecot proxy
by mtrainer＠cloud-free.com 08 May '14

08 May '14

Hi All, I need to import mailboxes into my Director NFS setup via one of my director proxy's as doing a direct dsync to the backend mailstores appears to giving me NFS locking issues. It looks like it may be possible to do this using doveadm listeners. I have setup doveadm listeners on a test proxy and backend mailstore. I am not sure how to make the dsync proxy through to the backend mailstore - it doesn't appear to be doing so below. My dovecot configs follow further below. Any help would be greatly appreciated.

[Dovecot] dsync replication does not replicate new subfolders
by Nikolaos Milas 08 May '14

08 May '14

Hello, Although this issue has been raised in another thread: https://www.mail-archive.com/dovecot@dovecot.org/msg57281.html I decided I should create a new one dedicated on it because that thread includes other issues as well, and the issue in question still remains unresolved although it is an important one (and I am hoping to attract Timo's attention on it, too ;-) ). The problem is that when dsync is configured between two servers (master/master), messages do get replicated, but newly created subfolders do not get replicated; as a result, when messages are moved by users from existing folders to newly created ones, replication results in chaos. Manually running a dsync command does not resolve the issue. See details of debug log on the above thread. I remind you that the configs of the two master/master installations (2.2.12) are available at: Primary Master: https://www.mail-archive.com/dovecot@dovecot.org/msg57298.html Secondary Master: https://www.mail-archive.com/dovecot@dovecot.org/msg57304.html The questions: 1. Is it an expected dsync behavior that newly created subfolders do not get replicated? 2. If yes, how can we replicate those? 3. If not, what is going wrong in the replication process? Does our configuration need a fix (which?) or does Dovecot needs one? Please advise! Sincerely, Nick

[Dovecot] TCP Cluster replication headache
by FUSTE Emmanuel 07 May '14

07 May '14

Hello, After going crazy building a dovecot cluster, I finally see the light ;-)) But some things are "strange" and could probably be fixed/enhanced. First : I follow the wiki doc, setting global doveadm_port. Things did not work, I've got: dovecot: doveadm(X1234567): Error: sync: /var/run/dovecot/auth-userdb: Configured passdbs don't support crentials lookups (to see if user is proxied, because doveadm_port is set) Same kind of error too when trying to use doveadm on the command line to get the replica status. My user/auth db is LDAP with "auth_bind = yes", but I don't understand the message in these context and did'nt know how to fix this. I tried to hardcode proxy/proxy_maybe property in the passdb declaration etc... Finally, I remove the global "doveadm_port 12345" and add ":12345" at the end of my "mail_replica =" line and all began to work ! Is it a wanted and expected error/fix ? Secondly: Now all is working and "doveadm replicator status '*' " correctly list all my users and the status, but after a few seconds (after replication kick in), I see all user listed twice. One time, as declared in the userdb with letters in uppercase : "X1234567" One time, in lowercase : "x1234567" On disk, all is OK, with only one replica in an uppercase directory. I initially think that it was a mismatch between userdb and passdb users return, but it was in fact the default value of auth_username_format that was the culprit. After going from the default %Lu to %u doveadm replicator status show only one entry per user as expected. Is it wanted and expected too? why auth_username_format is used/interact with/in the replication process and/or the replicator status command ? Not all is functionally tested, I go back to work. My is conf at the end of this message. Thanks Simo for this great piece of software.

[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.

[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] imap process and indexer-worker crash while creating folders
by Michael Kliewe 07 May '14

07 May '14

Hi, our dovecot processes sometimes crash when we create new folders. The "imap" process and the "indexer worker" process is crashing. We can reproduce this, we have a java program with multiple threads, and sometimes 2 threads try to create the same folder for the same user, and if both collide, dovecot processes crash. We don't see this happening in the real world if "normal" imap clients are connected, but our special java program trying to create folders in parallel is producing these crashes. Below you can see the log entries and gdb "bt full" output, one for an "imap" process and one for an "indexer worker" process. We are using dovecot 2.2.9, and I did not find anything in the changelog regarding this problem. Does ist make sense to try the newest version 2.2.12?

[Dovecot] sieve - different sieve scripts
by Héctor Moreno Blanco 07 May '14

Hello everybody, We have Dovecot 2.1.6 and PigeonHole 0.3.0. Is possible to have two different sieve scripts working at the same time? My sieve configuration in dovecot.conf: ... 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 imapflags notify ... sieve = %h/.dovecot.sieve sieve_dir = %h/sieve sieve_extensions = +imapflags +notify } protocols = imap pop3 sieve ... service managesieve-login { executable = /usr/local/dovecot/libexec/dovecot/managesieve-login inet_listener sieve { address = * port = 4190 } inet_listener sieve_deprecated { address = * port = 12000 } user = vmail } service managesieve { executable = /usr/local/dovecot/libexec/dovecot/managesieve } ... protocol sieve { managesieve_implementation_string = dovecot Pigeonhole managesieve_logout_format = bytes ( in=%i : out=%o ) managesieve_max_line_length = 65536 } Thank you very much in advanced.

[Dovecot] WG: on High Load using IMAPSYNC : Panic: file ostream-lzma.c: line 147: unreached. Dovecot 2.2.12 with zlib/XZ compression
by Robert Nowotny 07 May '14

07 May '14

when syncing Mailboxes with IMAPSYNC, using xz compression the dbox file gets corrupted. the same configuration was working ok on low load with xz compression. Dovecot Version 2.2.12 Linux Mint 16 EXT4 Filesystem another dovecot user already reported the same problem on the mailinglist, using dsync. That user switched to bz2 compression what worked for him. the answer was : > are you on latest patchlevel ? > there are some dsync fixes since 2.2.12 but it is not a problem of dsync. when looking at the code, we get here an unexpected returnvalue when flushing. I propose it would be good practice to write some logging in the default switch cases, to see the unexpected returnvalues in the errorlog. something like : ostream-lzma.c : -- Line 147 : i_unreached(); ++ Line 147 : i_fatal("unexpected lzma errorcode when flushing : %s", ret); after that modification the errorlog shows : May 6 14:03:05 vm-imap dovecot: imap(test): Fatal: lzma errorcode when flushing : (null) maybe You can also investigate and let me know when fixed. Here the log : May 5 14:53:10 vm-imap dovecot: imap(rrernboeck): Panic: file ostream-lzma.c: line 147: unreached May 5 14:53:10 vm-imap dovecot: imap(rrernboeck): Error: Raw backtrace: /usr/local/lib/dovecot/libdovecot.so.0(+0x67450) [0x7ff99d8ce450] -> /usr/local/lib/dovecot/libdovecot.so.0(+0x6752e) [0x7ff99d8ce52e] -> /usr/local/lib/dovecot/libdovecot.so.0(i_fatal+0) [0x7ff99d88955e] -> /usr/local/lib/dovecot/lib20_zlib_plugin.so(+0x4f0a) [0x7ff99ce87f0a] -> /usr/local/lib/dovecot/libdovecot.so.0(o_stream_flush+0x3e) [0x7ff99d8e6dbe] -> /usr/local/lib/dovecot/libdovecot.so.0(o_stream_nflush+0xf) [0x7ff99d8e71df] -> /usr/local/lib/dovecot/libdovecot.so.0(o_stream_nfinish+0x9) [0x7ff99d8e7229] -> /usr/local/lib/dovecot/libdovecot-storage.so.0(dbox_save_end+0x29) [0x7ff99db7cfa9] -> /usr/local/lib/dovecot/libdovecot-storage.so.0(mdbox_save_finish+0x39) [0x7ff99db76619] -> /usr/local/lib/dovecot/libdovecot-storage.so.0(mailbox_save_finish+0x4d) [0x7ff99dbb6a4d] -> dovecot/imap [rrernboeck 127.0.0.1 APPEND]() [0x40be09] -> dovecot/imap [rrernboeck 127.0.0.1 APPEND](command_exec+0x3c) [0x416cfc] -> dovecot/imap [rrernboeck 127.0.0.1 APPEND]() [0x40b491] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x27) [0x7ff99d8de527] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0xd7) [0x7ff99d8df2b7] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_run+0x38) [0x7ff99d8de0c8] -> /usr/local/lib/dovecot/libdovecot.so.0(master_service_run+0x13) [0x7ff99d88e753] -> dovecot/imap [rrernboeck 127.0.0.1 APPEND](main+0x2af) [0x40b06f] -> /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xf5) [0x7ff99d4c0de5] -> dovecot/imap [rrernboeck 127.0.0.1 APPEND]() [0x40b1cc] May 5 14:53:10 vm-imap dovecot: imap(rrernboeck): Fatal: master: service(imap): child 47957 killed with signal 6 (core dumped) May 5 14:53:10 vm-imap dovecot: imap(rrernboeck): Error: Corrupted dbox file /home/vmail/virtualmailboxes/rrernboeck/storage/m.1 (around offset=1302): msg header has bad magic value

I'm interested in using authentication via a UNIX socket as documented at http://wiki2.dovecot.org/AuthDatabase/Dict. (We are currently using a checkpassword script to enable us to authenticate against a django app that stores passwords in pbkdf2 format, but I'm concerned about scalability as we grow - specifically the comment about performance on http://wiki2.dovecot.org/AuthDatabase/CheckPassword) The example clearly shows retrieving a password, but is there some way to validate a password that was provided the way a checkpassword script does? Otherwise, for performance reasons, perhaps we should implement a new password scheme directly for dovecot? Thanks- Tom

Hi, in April I wrote an e-mail to the list, that with dovecot 2.2.12 on debian squeeze some pop3-sessions were killed sometimes. But I got no anwser from the list. At this was not a urgend problem and it happend very rarely it was not a big problem. But today it happend again more several times and I have no idea why. I have the following in my errorlog: ...

Hello, unfortunatly, TLS doesn't seem to work on LMTP, anyway, not by simply put ssl=yet to the lmtp inet_listener. I've tried and when I *openssl s_client -connect* to the lmtp listener I've got the following response : CONNECTED(00000003) 34379118248:error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol:/usr/src/secure/lib/libssl/../../../crypto/openssl/ssl/s23_clnt.c:766: My postfix server can't neither establish a TLS connection on LMTP listener.

[Dovecot] Status of sieve-extdata?
by Jiri Bourek 06 May '14

06 May '14

Hi, I'd like to ask about status of extdata plugin for sieve. The wiki page (http://wiki2.dovecot.org/Pigeonhole/Sieve/Plugins/Extdata) mentions versions for PigeonHole 0.2 and 0.3, but there seems to be no version for 0.4 and Dovecot 2.2. Is the plugin dead or is it planned to make version for Dovecot 2.2 (when time allows I guess)? Regards J.

[Dovecot] on High Load using IMAPSYNC : Panic: file ostream-lzma.c: line 147: unreached. Dovecot 2.2.12 with zlib/XZ compression
by Robert Nowotny 06 May '14

06 May '14

when syncing Mailboxes with IMAPSYNC, using xz compression the dbox file gets corrupted. the same configuration was working ok on low load with xz compression. Dovecot Version 2.2.12 Linux Mint 16 EXT4 Filesystem another dovecot user already reported the same problem on the mailinglist, using dsync. That user switched to bz2 compression what worked for him. the answer was : > are you on latest patchlevel ? > there are some dsync fixes since 2.2.12 but it is not a problem of dsync. when looking at the code, we get here an unexpected returnvalue when flushing. I propose it would be good practice to write some logging in the default switch cases, to see the unexpected returnvalues in the errorlog. something like : ostream-lzma.c : -- Line 147 : i_unreached(); ++ Line 147 : i_fatal("unexpected lzma errorcode when flushing : %s", ret); I will try to change it and let You know. maybe You can also investigate and let me know when fixed. Here the log : May 5 14:53:10 vm-imap dovecot: imap(rrernboeck): Panic: file ostream-lzma.c: line 147: unreached May 5 14:53:10 vm-imap dovecot: imap(rrernboeck): Error: Raw backtrace: /usr/local/lib/dovecot/libdovecot.so.0(+0x67450) [0x7ff99d8ce450] -> /usr/local/lib/dovecot/libdovecot.so.0(+0x6752e) [0x7ff99d8ce52e] -> /usr/local/lib/dovecot/libdovecot.so.0(i_fatal+0) [0x7ff99d88955e] -> /usr/local/lib/dovecot/lib20_zlib_plugin.so(+0x4f0a) [0x7ff99ce87f0a] -> /usr/local/lib/dovecot/libdovecot.so.0(o_stream_flush+0x3e) [0x7ff99d8e6dbe] -> /usr/local/lib/dovecot/libdovecot.so.0(o_stream_nflush+0xf) [0x7ff99d8e71df] -> /usr/local/lib/dovecot/libdovecot.so.0(o_stream_nfinish+0x9) [0x7ff99d8e7229] -> /usr/local/lib/dovecot/libdovecot-storage.so.0(dbox_save_end+0x29) [0x7ff99db7cfa9] -> /usr/local/lib/dovecot/libdovecot-storage.so.0(mdbox_save_finish+0x39) [0x7ff99db76619] -> /usr/local/lib/dovecot/libdovecot-storage.so.0(mailbox_save_finish+0x4d) [0x7ff99dbb6a4d] -> dovecot/imap [rrernboeck 127.0.0.1 APPEND]() [0x40be09] -> dovecot/imap [rrernboeck 127.0.0.1 APPEND](command_exec+0x3c) [0x416cfc] -> dovecot/imap [rrernboeck 127.0.0.1 APPEND]() [0x40b491] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x27) [0x7ff99d8de527] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0xd7) [0x7ff99d8df2b7] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_run+0x38) [0x7ff99d8de0c8] -> /usr/local/lib/dovecot/libdovecot.so.0(master_service_run+0x13) [0x7ff99d88e753] -> dovecot/imap [rrernboeck 127.0.0.1 APPEND](main+0x2af) [0x40b06f] -> /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xf5) [0x7ff99d4c0de5] -> dovecot/imap [rrernboeck 127.0.0.1 APPEND]() [0x40b1cc] May 5 14:53:10 vm-imap dovecot: imap(rrernboeck): Fatal: master: service(imap): child 47957 killed with signal 6 (core dumped) May 5 14:53:10 vm-imap dovecot: imap(rrernboeck): Error: Corrupted dbox file /home/vmail/virtualmailboxes/rrernboeck/storage/m.1 (around offset=1302): msg header has bad magic value

[Dovecot] doveadm auth and the "nologin" extra field
by Axel Luttgens 05 May '14

05 May '14

Hello, Still busy with details... Considering, as in my previous example, a password_query returning '!' or NULL for the "nologin" column, depending on an account's status (suspended or not). Let's consider a suspended user "some.user". In the case of a successful authentication, one has: sh-3.2# doveadm auth test some.user goodpassword; echo $? passdb: some.user auth succeeded extra fields: user=some.user nologin 0 On the other hand, in the case of an authentication failure: sh-3.2# doveadm auth test some.user badpassword; echo $? passdb: some.user auth failed extra fields: user=some.user nologin=! 77 So, this is similar to what happens in a connection (pop3, imap...): when present, the nologin info is always taken into account, even in the case of an authentication failure. Again, this may raise some concerns about the consistency of such a behavior. Is this guaranteed to always behave that way, because of some rationale I'm currently missing, or does it go about some overlooked combination, liable to be inadvertently "corrected" in the future? I haven't been able to find a definitive answer in the wiki or in the code about such matters. This is particularly important in the case of doveadm, since its output requires parsing for extracting such informations (the exit code alone isn't sufficient); should above behavior be changed without notice, and a script could suddenly take the worst decisions... BTW, why: nologin in the first output, and: nologin=! in the second output? TIA, Axel
