Released Pigeonhole v0.4.8.rc3 for Dovecot v2.2.17
by Stephan Bosch 14 May '15

14 May '15

Hello Dovecot users, RC2 had one more important bug caused by the new sieve_default_name feature. To prevent causing more of such rather stupid bugs in the future, I created an external shell-based test suite to test dovecot-lda delivery, the doveadm sieve tools and ManageSieve. These kind of tests aren't possible with the current Sieve-based test suite that is included in the Pigeonhole tarball. Now I can test most basic top-level Pigeonhole functionality in one go. Additionally, I created one new feature for ManageSieve. It allows logging various statistics at client disconnect, much like POP3 currently supports. This is e.g. useful for debugging. In the process, I fixed a few ManageSieve bugs as well. If RC3 doesn't cause any more issues, I will release 0.4.8 this Friday. Changelog v0.4.8 (updated): * LDA Sieve plugin: Dovecot changed the deliver_log_format setting to include %{delivery_time}. This prompted changes in Pigeonhole that make this release dependent on Dovecot v2.2.17. + Implemented magic to make sieve_default script visible from ManageSieve under a configurable name. This way, users can see the default rules, edit them and store a private adjusted version. This could also be achieved by copying the default script into the user's script storage, but updates to the global sieve_default script would be ignored that way. + ManageSieve: Implemented support for reporting command statistics at disconnect. Statistics include the number of bytes and scripts uploaded/downloaded/checked and the number of scripts deleted/renamed. - Fixed problem in address test: erroneously decoded mime-encoded words in address headers. - extprograms plugin: Fixed failure occurring when connecting to script service without the need to read back the output from the external program. - Fixed bug in script storage path normalization occurring with relative symbolic links below root. - Fixed and updated various parts of the documentation - ManageSieve: Used "managesieve" rather than "sieve" as login service name, which means that all managesieve-specific settings where ignored. - Managesieve: Storage quota was not always enforced properly for scripts uploaded as quoted string. Nobody uses that, but it is allowed in the specification and we support it, so it should work properly. The release is available as follows: http://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.8.rc3… http://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.8.rc3… 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

v2.2.17 release candidate 2 released
by Timo Sirainen 13 May '15

13 May '15

http://dovecot.org/releases/2.2/rc/dovecot-2.2.17.rc2.tar.gz http://dovecot.org/releases/2.2/rc/dovecot-2.2.17.rc2.tar.gz.sig Changes since rc1: - Compiling fix for fs-compress in Solaris and maybe others. - Implemented Cassandra CQL support as lib-sql backend. This is mainly usable as dict-sql backend. - lib-fts fixes and improvements - Some other small random changes If no new issues are found, v2.2.17 final should be out in a day or two. (Actually looks like I have a few more bugs that probably will be fixed for it.) Changes since v2.2.16: * Dovecot no longer checks or warns if a mountpoint is removed. This was causing more trouble than it was worth. Make sure that all the mountpoints that Dovecot accesses aren't writable by mail processes when they're unmounted. * dict server wasn't properly escaping/unescaping data. Fixing this broke backwards compatibility with data that contains line feeds. This hopefully affects only very few installations. If you're using dict to save multiline data (Sieve scripts to SQL), you may be affected. * imap: SPECIAL-USE capability is no longer advertised if there are no special_use flags specified for any mailboxes. + lmtp: Added lmtp_hdr_delivery_address setting to specify whether to include email address in Delivered-To: and Received: headers. + Added initial version of full text search library, which includes language-specific text normalization and filtering. This is still in development, but it's already possible to use for testing with fts-lucene and fts-solr. + lda, lmtp: deliver_log_format can now include %{delivery_time}, which expands to how many milliseconds it took to deliver the mail. With LMTP %{session_time} also expands to how many milliseconds the LMTP session took, not including the delivery time. + lmtp proxy: Mail delivery logging includes timing information. + imap: Most IMAP commands now include in the tagged reply how many milliseconds it took to run the command (not counting the time spent on waiting for the IMAP client to read/write data). + director: Implemented director_proxy_maybe passdb extra field to be able to run director and backend in the same Dovecot instance. (LMTP doesn't support mixed proxy/non-proxy destinations currently.) + doveadm: Added -F <file> parameter to read a list of users from the given file and run the command for all the users. This is similar to -A parameter reading the list of users from userdb lookup. + Implemented initial Cassandra CQL support as lib-sql backend. It's only usable as dict backend currently. - auth: If auth_master_user_separator was set, auth process could be crashed by trying to log in with empty master username. - imap-login, pop3-login: Fixed crash on handshake failures with new OpenSSL versions (v1.0.2) when SSLv3 was disabled. - auth: If one passdb fails allow_nets check, it shouldn't have failed all the other passdb checks later on. - imap: Server METADATA couldn't be accessed - imapc: Fixed \Muted label handling in gmail-migration. - imapc: Various bugfixes and improvements. - Trash plugin fixes by Alexei Gradinari - mbox: Fixed crash/corruption in some situations when the first mail was expunged.

dovecot-lda panics when postmaster_address is given on command line
by Onno Molenkamp 13 May '15

13 May '15

Hi, When passing a postmaster_address to dovecot-lda on the command line with -o, it panics: $ ./dovecot-lda -o postmaster_address=anything lda(onno,)Panic: file lda-settings.c: line 80 (lda_settings_check): assertion failed: (set->postmaster_address[0] == SETTING_STRVAR_UNEXPANDED[0]) It looks like postmaster_address has already been expanded at that point when it's given on the command line. (set->postmaster_address[0] is "1") I'm running v2.2.15, but with v2.2.17.rc1 the same thing happens. Regards, Onno

Some mail readers have auto-discover features that are rather stupid. If possible, manually configure the SSL style (TLS/STARTTLS) and port rather than letting it guess. To diagnose whether it is some dovecot config error, you can manually connect with both flavours of SSL openssl s_client -connect 192.168.0.15:993 ... or ... openssl s_client -starttls imap -connect 192.168.0.15:143 then if it gets past the SSL handshake, a login <user> <password> to test the authentication part. This will at least tell you whether it's a client side or server side issue. (However, since it is working with other client, it's probably a client side issue.) Joseph Tam <jtam.home(a)gmail.com>

Bug#776094: dovecot-imapd: corrupts mailbox after trying to retrieve it (fwd)
by Santiago Vila 11 May '15

11 May '15

Hello. I wrote about this three weeks ago but got no answer. I'm going to officially "forward" the Debian bug this time, with all the details. The test case is just 840 bytes long. Please give it a try. ---------- Forwarded message ---------- From: Santiago Vila <sanvila(a)unex.es> To: submit(a)bugs.debian.org Date: Fri, 23 Jan 2015 22:32:28 +0100 (CET) Subject: dovecot-imapd: corrupts mailbox after trying to retrieve it Package: dovecot-imapd Version: 1:2.2.13-11 Severity: serious The following mbox folder, when put in $HOME/mail, becomes corrupted after trying to retrieve it with fetchmail. The problem may be reproduced by using the same machine as server and client: * Put "inbox-b" in $HOME/mail * Put this in $HOME/.fetchmailrc server localhost proto imap port 143: user "someuser" pass "thepassword" * Retrieve email using this command line: fetchmail -a localhost --folder inbox-b -m "true" Note: By looking at the "true" above it is clear that whatever fetchmail does with the message is not important at all. You will see something like this: 12 messages for someuser at localhost (folder inbox-b). reading message someuser@localhost:1 of 12 (171 header octets) (3 body octets) flushed reading message someuser@localhost:2 of 12 (245 header octets) (3 body octets) flushed reading message someuser@localhost:3 of 12 (245 header octets) (3 body octets) flushed reading message someuser@localhost:4 of 12 (245 header octets) (3 body octets) flushed reading message someuser@localhost:5 of 12 (245 header octets) (3 body octets) flushed reading message someuser@localhost:6 of 12 (171 header octets) (3 body octets) flushed reading message someuser@localhost:7 of 12 (171 header octets) (3 body octets) flushed reading message someuser@localhost:8 of 12 (245 header octets) (3 body octets) flushed reading message someuser@localhost:9 of 12 (245 header octets) (3 body octets) flushed reading message someuser@localhost:10 of 12 (245 header octets) (3 body octets) flushed reading message someuser@localhost:11 of 12 (245 header octets) (3 body octets) flushed reading message someuser@localhost:12 of 12 (273 header octets)fetchmail: incorrect header line found - see manpage for bad-header option not flushed And in fact "inbox-b" in the server is now like this: [...] >From root(a)example.com Tue Jan 13 10:18:20 2015 rstuvwxyzabcdefghijklmnopqrstuvwxyz(a)example.com To: a(a)example.com Subject: a MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Message-Id: <20150113091737.B5ADA5F8B1(a)example.com> Date: Tue, 13 Jan 2015 10:17:25 +0100 (CET) X-UID: 16035 Status: O a Note how the From: line has been truncated from its original state.

Dovecot is not reading connections from iOS devices correctly. Any ideas?
by Robert Chalmers 11 May '15

11 May '15

From the dovecot logs. dovecot-info.log May 11 09:27:45 imap-login: Info: Aborted login (no auth attempts in 0 secs): user=<>, rip=192.168.0.1, lip=192.168.0.15, session=<pXcBJ8oVbgDAqAAB> dovecot-debug.log May 11 09:27:45 auth: Debug: auth client connected (pid=17388) When I try to connect using either the iOS Mail app, or Outlook mail app, nothing happens at al with ssl, and if I use plain login the iOS device tells me I have either the username or password wrong - which I haven't. Connection from Mac with MailMate works fine. iOS doesn't. so I'm stumped. I can't see why this is refusing the connection.

Full text search indexes not used for header/body OR queries?
by Robert L Mathews 09 May '15

09 May '15

I've noticed that when using Lucene full text search, most queries use the indexes and/or header cache and are fast: . SEARCH BODY test . OK Search completed (0.001 secs). . SEARCH SUBJECT test . OK Search completed (0.053 secs). . SEARCH BODY test SUBJECT test . OK Search completed (0.002 secs). . SEARCH OR SUBJECT test FROM test . OK Search completed (0.093 secs). But an OR query that mixes headers and body does not use the available FTS indexes for the BODY part and is slow: . SEARCH OR BODY test SUBJECT test * OK Searched 62% of the mailbox, ETA 0:05 * OK Searched 70% of the mailbox, ETA 0:04 . OK Search completed (15.147 secs). Is this the expected behavior? Since the FTS code can handle an AND of header and body searches, I'm surprised it doesn't do the same for an OR. I noticed this while tracking down poor performance in Thunderbird, which issues searches like this: UID SEARCH RETURN (ALL) (OR FROM "Evelyn" (OR SUBJECT "Evelyn" (OR TO "Evelyn" (OR CC "Evelyn" BODY "Evelyn")))) NOT DELETED These are slow even with FTS enabled because of this behavior. I'm using Dovecot 2.1.7 from Debian wheezy. (I know this is outdated; however, I've examined the 2.1.x and 2.2.x changelogs and found no mention of it.) -- Robert L Mathews, Tiger Technologies, http://www.tigertech.net/

PublicFolders using Maildir and INDEXPVT in Dovecot v2.2.13
by Panayiotis Fafakos 08 May '15

08 May '15

Dear all, we have succesfully configured Dovecot v2.2.13 in debian wheezy 7.8 (using backports) using Maildir structure, to use private index files for the \Seen flag on a per user basis. All users access their emails and Public Folders using IMAP protocol. The problem is that when a user moves an email from publicFolderA to publicFolderB under the same namespace the other users see this message as unread, although they have actually read it when it was in publicFolderA. Please note that this is an old message which has been moved , it was not copied, so the actual UID should be the same... Is there a way to keep the \Seen flag for the messages that are moved from folder to folder? Is there a way to keep the \Seen flag in a database, so that we can ignore the folder structure and only check the message UIDs? We could use MySQL, PgSQL or even SQLite... Below follows the Public-Folder namespace declaration: ------------------------------------------ namespace { inbox = no location = maildir:/var/vmail/Public-Folders:LAYOUT=fs:INDEXPVT=~/Maildir/public/%u prefix = Public-Folders/ separator = / subscriptions = no type = public } ------------------------------------------ With the above system configuration we have the complete folder structure under ~/Maildir/public/%u, and many log files, one for each folder a user has accessed. Could we only have one index file for each user for all the public folder structure under the same namespace? Kind regards to all, Panayiotis Fafakos

Different mdbox_rotate_size for primary and alternate storage
by Paolo Cravero 08 May '15

08 May '15

Hello. In order to speed up backups of very very old messages I would like to set two different limits for mdbox_rotate_size. Like, 50M for primary storage and 100M or larger for alternate storage. There is no mention in docs or such a possibility, so I assume it is not possible. Is that correct? While I am at it, is it possible to configure primary storage as maildir (sturdy indexes) and altstorage as mdbox (more delicate indexes)? Thanks, Paolo

Dovecot and data migration
by Alain BERNARD 07 May '15

07 May '15

Hi, Our legacy data store retains a single copy of a message regardless of the number of mailboxes in which that message resides. It does this by creating hard links to that message in the mailboxes containing that message. Thus, when we perform data migration to the server target (Dovecot), the copies of the same message are copied over with the migration process (imapsync). We use the storage format maildir. With a small message store, this means that a lot of messages are duplicated unnecessarily. How to reduce message store size due to duplicate storage of identical messages ? Does a relinking function exist and can be run in real-time mode ? how can we configure Dovecot to deduplicate for all users using a hash to determine whether the file could be already exist ? Thanks in advance. Memo

Mapping other Inbox method (symlink vs ACL)

Hi, I am trying to map a account(bob(a)mydomain.com) to help(a)mydomain.com. I would like him to see/access Inbox,Sent,Junk,Trash of help(a)mydomain.com . What would you reckon would be the best way to do this? ACL or Symlink? With symlink, I dont think I will be able to set permissions. Is it possible to use ACL to get the entire email account access(the inbox, junk, sent etc.)?

lmpt director and ldap userdb
by Angel L. Mateo 06 May '15

06 May '15

Hello, I've been using dovecot for a long time, but now I'm having troubles with I change I need to make. I have a director server in front of two backend servers. All of these servers are running dovecot 2.1.16. Redirection to backend servers are based in an attribute of a ldap server. My users are defined in this same ldap server. At this moment, for user authentication we use password lookups. My current configuration at both frontend and backend servers is attached. But now I need to change it to bind authentication, so the only change I've made is changing "auth_bind=no" to "auth_bind=yes". After this change, backend servers are working fine. Director servers are also working for POP and IMAP connections, but for LMTP they are returning: May 6 10:23:35 myotis40 dovecot: lmtp(48026): Error: user myuser(a)um.es: Auth PASS lookup failed This error is returned without any ldap lookup, neither connection to backend servers. Any help? thanks in advance. -- Angel L.

only mark as deleted when deleted as default for some mailboxes
by zucca＠systemschmiede.com 06 May '15

06 May '15

Hi list, i wonder if this is possible with some dovecot configuration. Selected mailboxusers will only mark their mails as deleted, when a mail is being deleted through any client. No automatic expunge. This is default behaviour in Outlook, and i think in Thunderbird too, but unfortunately not in Open-Xchange for example. So i was asking myself if it would be possible to simply turn this feature on maybe globally and as a default for some users. Thank you very much for your reply.

dovecot-proxy with managesieve, director and backend dovecot imap
by George Vieira 06 May '15

06 May '15

hi all, I've been tasked to add sieve/managesieve to an existing dovecot cluster running 2.1.7 on debian wheezy which is made up of 2 dovecot-proxy hosts as directors and some back end dovecot imap hosts all running the same version. My problem is that I thought to put the service on the director/proxy hosts since they wouldn't have too much load on it, but when I do I get the following error: Apr 28 11:00:28 master: Info: Dovecot v2.1.7 starting up (core dumps disabled) Apr 28 11:00:28 config: Warning: service auth { client_limit=50000 } is lower than required under max. load (60000) Apr 28 11:00:34 managesieve-login: Error: proxy: host not given: user=<mailchannel(a)mydomain.net>, method=PLAIN, rip=192.168.100.207, lip=192.168.100.119, TLS, session=<3/zPY74UOgDAqGTP> Apr 28 11:00:34 managesieve-login: Info: Aborted login (internal failure, 1 succesful auths): user=<mailchannel(a)mydomain.net>, method=PLAIN, rip=192.168.100.207, lip=192.168.100.119, TLS, session=<3/zPY74UOgDAqGTP> From searching around, only ever saw 1 result which was to add "executable = managesieve-login director" to the managesieve service, but this made no difference at all and the error is the same. So I tried to instead use the back end imap servers, but they throw errors expecting the users password to be the common proxy/director password as below: passdb { driver = static args = user=%u password=crypticpasswordagain } Apr 28 12:03:37 auth: Debug: static(mailchannel(a)mydomain.net,192.168.100.207,<17RTRb8UpADAqGTP>): lookup Apr 28 12:03:37 auth: Info: static(mailchannel(a)mydomain.net,192.168.100.207,<17RTRb8UpADAqGTP>): Password mismatch Apr 28 12:03:37 auth: Debug: static(mailchannel(a)mydomain.net,192.168.100.207,<17RTRb8UpADAqGTP>): PLAIN(85387v92394jks) != 'crypticpasswordagain' Apr 28 12:03:39 auth: Debug: client out: FAIL 1 user=mailchannel(a)mydomain.net So with configs below, how is it best to run managesieve that takes the correct login/password without directing to the cluster (or direct if it's easier but must use real user password)? -- dovecot proxy config -- #

[sieve] extracting address behavior changes beetwen 2.2.13 and 2.2.16
by Marcin Mirosław 05 May '15

05 May '15

Hi all! After upgrading dovecot from 2.2.13 to 2.2.16 I noticed that my sieve filters doesn't catch some emails. I used sieve-test with tracing (it's great tool!) and I can see as below: part of sieve filter: [...] elsif address :is "From" "backup(a)areda.pl" { [...] dovecot-2.2.13: 36: address test 36: starting `:is' match with `i;ascii-casemap' comparator: 36: extracting `From' headers from message 36: parsing address header value `=?UTF-8?B?QmFjdWxhQEFUTQ==?= <backup(a)areda.pl>' 36: extracting `all' part from address `backup(a)areda.pl' 36: matching value `backup(a)areda.pl' 36: with key `backup(a)areda.pl' => 1 36: finishing match with result: matched 36: jump if result is false 36: not jumping dovecot-2.2.16: 36: address test 36: starting `:is' match with `i;ascii-casemap' comparator: 36: extracting `From' headers from message 36: parsing address header value `Bacula@ATM <backup(a)areda.pl>' 36: extracting `all' part from address `Bacula@ATM' 36: matching value `Bacula@ATM' 36: with key `backup(a)areda.pl' => 0 36: finishing match with result: not matched 36: jump if result is false 36: jumping to line 43 So in newer dovecot sieve uses comment not exact email address. Did I wrongly wrote my sieve script? Thanks, Marcin.

Dovecot 2.2.16 doesn't rotate mdbox files
by Басов Евгений 04 May '15

04 May '15

Hello, there's setting in my config file: mail_location = mdbox:/var/vmail/%Ld/%Ln:INDEX=/var/indexes/%Ld/%Ln mdbox_rotate_size = 1M mdbox_preallocate_space = yes mdbox_rotate_interval = 1d As I understand, this settings means that file which contains letters with refcount=0 will be rotated after 23:59 today. I remember letter ID and execute grep whith this one in storage directory. Letter was presented. After that, I removed letter over IMAP protocol, checked and find it again. On the next day check with grep was repeated and letter was finded. After doveadm purge -u user@domain letter was expunged. What's wrong in my configuration?

backup mails from alternate storage
by Lars Täuber 04 May '15

04 May '15

Hi there! It seems that # doveadm backup -v backup -fu $MUSER mdbox:"$BKPDIR/$MUSER/mdbox" doesn't backup all messages stored in alternate storage. mail_location = mdbox:~/mdbox:ALT=/srv/mail/slow/vmail/%n/mdbox I don't know how to debug this. The sizes of the mailboxes in the filesystems of user C are strange: ~/mdbox: # du -sm 2169 ALT: # du -sm 25252 backup: # du -sm 2658 This is with dovecot 2.2.9 on Ubuntu x86_64 14.04.2 LTS. Is this a bug or am I doing something wrong? How can I test if messages stored in the alternate storage are successfully backed up? Thanks Lars

Fatal: Unknown scheme: SHA512-CRYPT. On a Mac-mini
by Robert Chalmers 02 May '15

02 May '15

Running postfix+dovecot+mysql on a mac-mini, and trying to solve this puzzle. Is this a Mac issue?, a MySQL issue? or something I haven't configured in? You can see from the output of the samples shows in the first case, that SHA512-CRYPT seems to be Unknown. The code I used is from a Linux based tutorial on setting up Postfix+Dovecot+MySQL on a site. Everything is generally going ok, apart from this bit. There are some others unknown as well. The codes used to create my database of passwords follows these output examples. MacMini:~ robert$ sudo doveadm pw -s SHA512-CRYPT -p 123456 Fatal: Unknown scheme: SHA512-CRYPT MacMini:~ robert$ sudo doveadm pw -s SHA512 -p 123456 {SHA512}ujJTh2rta8ItSm/1PYQGxq2GQZXtFEq1yHYhtsIztUi66uaVbfNG7IwX9eoQ817jy8UUeX7X3dMUVGTioLq0Ew== MacMini:~ robert$ sudo doveadm pw -s SHA256 -p 123456 {SHA256}jZae727K08KaOmKSgOaGzww/XVqGr/PKEgIMkjrcbJI= MacMini:~ robert$ sudo doveadm pw -s MD5 -p 123456 {MD5}$1$.mAQzPhO$6v/WxTUt.Y1lhopkMarEb0 MacMini:~ robert$ sudo doveadm pw -s MD5-CRYPT -p 123456 {MD5-CRYPT}$1$gNkYwx/o$3nQLmUIPOBmZdR/e/EXFV1 MacMini:~ robert$ sudo doveadm pw -s BLF-CRYPT -p 123456 Fatal: Unknown scheme: BLF-CRYPT MacMini:~ robert$ sudo doveadm pw -s SHA512 -p 1pass66U! {SHA512}EuuO6BAt+bgzXIOw7XIdiVBFwdEZ2tGqHOJ/DSTSkD+ikw7GQQo+KtHSta7p3KNv2AEVKtfOuyl5UeCEqnKogg== MacMini:~ robert$ sudo doveadm pw -s SHA256-CRYPT -p 1pass66U!

Which seems to work fine, and creates the table as it should - even though the resulting password doesn't appear to be quite right for SHA512-CRYPT INSERT INTO `mailserver`.`virtual_users` (`id`, `domain_id`, `password` , `email`) VALUES ('1', '1', ENCRYPT('firstpassword', CONCAT('$6$', SUBSTRING(SHA(RAND()), -16))), 'email1(a)example.com'), ('2', '1', ENCRYPT('secondpassword', CONCAT('$6$', SUBSTRING(SHA(RAND()), -16))), 'email2(a)example.com'); What it actually creates is this: This is not a SHA512-CRYPT password?? mysql> SELECT * FROM mailserver.virtual_users; 3 | 1 | $6jxK9DWPBrAc | robert(a)zeus.example.com Just to be clear,. this is the section of the Dovecot configs that deals with handling this. BUT.. On the MAC-Mini, SHA512-CrYPT is unknown. # List of supported schemes is in # http://wiki2.dovecot.org/Authentication/PasswordSchemes # default_pass_scheme = SHA512-CRYPT So the question is, what Encryption should I be using, and is this an Apple thing, or a MySQL thing?

Postpone email delivery with LMTP and Postfix
by Miloslav Hůla 01 May '15

01 May '15

Hi, is there any way, based on userdb/passwdb attribute, how to postpone an email delivery? The purpose is, I need to freeze an account (Maildir++) for a few minutes and new email must not be delivered. But emails must be delivered when account is unfrozen. I found few things about Postfix filters, but I'm not sure it's a good way. Thank you, Milo

A question about Configure time options, and base directories and Defaults?
by Robert Chalmers 30 Apr '15

30 Apr '15

I originally downloaded the sources a few weeks ago, dovecot-2.2.16, and simply did a ./configure make make install I'm running OSX 10.10.3 on a mac-mini. Not being too sure that I was going to go ahead with this whole idea... in any event, I did. BUT... most documentation I come across as I search for answers refers to the base directories being below /etc - as in postfix actually. ie; /etc/dovecot /etc/postfix Which seems logical to me - and appears to be a "default" or standard, at least in most documentation. However, my cavaliere installation put everything below /usr/local, as in /usr/local/etc/dovecot Which has caused me no end of fiddling as I try and remember where things are when I'm working on config files. There even appears to be a /private/etc/dovecot folder, which I seem to have somehow created about a month ago??? but is empty anyway. So, on my Mac I now have these folders/directories. These may have been created by a previous attempt, or by an installation to CutedgeSystems Mailserve. Now redundant. /private/etc/dovecot <---- empty /private/etc/pam.d/dovecot <--- contains login, pop3, ssh etc etc /private/var/spool/postfix/private/dovecot <-- this is a link to the one just above ??? or the other one is a link to this? /usr/libexec/dovecot <-- this contains a link to dovecot-lda [dovecot-lda -> /usr/local/libexec/dovecot/dovecot-lda] that I put in myself because that's where dovecot was looking for it. ========= everything below this line is as a result of the installation from source /usr/local/cutedge/dovecot /usr/local/etc/dovecot /usr/local/include/dovecot /usr/local/lib/dovecot /usr/local/libexec/dovecot /usr/local/sbin/dovecot /usr/local/share/doc/dovecot /usr/local/var/lib/dovecot /usr/local/var/run/dovecot I see from this list in someone else's post, that it's obviously possible - and I should have remembered - to put the files where ever I want them. i.e. /etc/dovecot If I read this list right, it will put the installation into /etc/dovecot - with some in other, appropriate directories. NOT all below /user/local as I have done. --prefix=/usr \ --sysconfdir=/etc \ --libexecdir=\${prefix}/lib \ --localstatedir=/var \ --mandir=\${prefix}/share/man \ --infodir=\${prefix}/share/info \ --with-moduledir=\${prefix}/lib/dovecot/modules \ --disable-rpath \ --disable-static Now for the burning question. Is it possible now to re-configure, then reinstall into the more appropriate directories, then copy the configuration files over. Make the appropriate weeks, and remove the original /usr/local/xxxx installation? Or is that just a step too far for the sake of what is essentially window dressing. The system I might add appears to be working as is? Thanks for any advice from the experts. (Sorry if the formatting in this post gets screwed up. It;s gmail;s web interface) Robert

doveadm -D and -v options
by Reuben Farrelly 30 Apr '15

30 Apr '15

According to doveadm-dsync man page the above two options are valid, but they are rejected when used: tornado # doveadm backup -v -u testuser remote:pi.me.name:4814 backup: invalid option -- 'v' doveadm backup [-u <user>|-A] [-S <socket_path>] [-fPRU] [-l <secs>] [-r <rawlog path>] [-m <mailbox>] [-g <mailbox_guid>] [-n <namespace> | -N] [-x <exclude>] [-s <state>] -d|<dest> tornado # tornado # doveadm backup -D -u testuser remote:pi.me.name:4814 backup: invalid option -- 'D' doveadm backup [-u <user>|-A] [-S <socket_path>] [-fPRU] [-l <secs>] [-r <rawlog path>] [-m <mailbox>] [-g <mailbox_guid>] [-n <namespace> | -N] [-x <exclude>] [-s <state>] -d|<dest> tornado # This is with 2.2.16 (latest -hg). Looks to me like either a bug, or the documentation (man doveadm-sync) is incorrect...? Reuben

quota_over_flag examples?
by E.B. 30 Apr '15

30 Apr '15

I can't find any posts on this list for peoples using quota_over_flag http://wiki2.dovecot.org/Quota/Configuration#Overquota-flag_.28v2.2.16.2B-.… If my userdb is sql what would be best script to use in terms of performance? (I mean if over-quota-flag triggers script every time it changes and the script calls CLI mysql client isn't all this so expensive to spawn a new shell session which spawns a mysql client?) Anyone knows how to use this flag with postfix *making postfix send special reject* "user over quota" note instead of plain SMTP reject?? Is an additional database lookup (restriction class?) unavoidable? :( TIA1 PS Looks like it is tricky almost impossible to make postfix do rejects based on this flag for aliases. (Special query would be a little messy for our schema but i dunno at what point postfix resolves aliases?)

lda and lmtp error after upgrading dovecot
by giorgio paolucci 29 Apr '15

29 Apr '15

Hello everybody, after upgrading dovecot on a debian wheezy installation from the standard package version (dovecot 2.1.7) to dovecot 2.2.13-11 from wheezy-backports, i noticed some errors in my logs... Apr 28 22:00:13 lmtp(4879, xxxxxxxxx(a)unipd.it) Info: copy from <lmtp DATA>: box=INBOX, uid=error, msgid=<20150428200011.47D801F32(a)mydoom.unipd.it>, size=1523 They are not frequent but still coninuing since the upgrade.

Trash Plugin bugs
by Alexei Gradinari 29 Apr '15

29 Apr '15

dovecot v2.2.16 I've found a few bugs in Trash plugin. 1. If Quota set only messages limit (without storage limit) then Trash plugin does not expunge any message because Quota plugin sets too_large_r=TRUE. It's because quota_default_test_alloc function does not check if bytes_limit is set. /* if size is bigger than any limit, then it is bigger than the lowest limit */ - if (size > bytes_limit) { + if (bytes_limit > 0 && size > bytes_limit) { *too_large_r = TRUE; break; } 2. Trash plugin does not use bytes_ceil/count_ceil to calculate size_needed/count_needed to expunge. Trash plugin may expunge more messages that nedeed. + if (ctx->bytes_ceil!=(uint64_t)-1 && ctx->bytes_ceil < size + ctx->bytes_over) { + size_needed = size + ctx->bytes_over - ctx->bytes_ceil; + } + if (ctx->count_ceil!=(uint64_t)-1 && ctx->count_ceil < 1 + ctx->count_over) { + count_needed = 1 + ctx->count_over - ctx->count_ceil; + } + /* not enough space. try deleting some from mailbox. */ - ret = trash_try_clean_mails(ctx, size + ctx->bytes_over, - 1 + ctx->count_over); + ret = trash_try_clean_mails(ctx, size_needed, count_needed); 3. Trash plugin does not check 'unlimited' values in bytes_ceil/count_ceil and may overflow them when add expunged size/messages - ctx->bytes_ceil += size_expunged; - ctx->count_ceil += expunged_count; + if (ctx->bytes_ceil!=(uint64_t)-1) { + ctx->bytes_ceil += size_expunged; + } + if (ctx->count_ceil!=(uint64_t)-1) { + ctx->count_ceil += expunged_count; + } See attached patch.

Quotas not working after reboot
by Edgaras Lukoševičius 28 Apr '15

Hello, after rebooting my dovecot server quotas are no longer working. # dovecot --version 2.2.10 CentOS Linux release 7.0.1406 It is strange that restarting dovecot did not reveal this problem, but rebooting whole server did. Before reboot it was like this: # doveadm -D quota get -u test1(a)testdomain1.tld doveadm(root): Debug: Loading modules from directory: /usr/lib64/dovecot doveadm(root): Debug: Module loaded: /usr/lib64/dovecot/lib10_quota_plugin.so doveadm(root): Debug: Loading modules from directory: /usr/lib64/dovecot/doveadm 03NB0d9erYBwhnzXhbS66fLDMU8v4ZiCDQDM3tDHCKme4ujpHy/lRk33305AIO9UXtgHGFyJYSpcVgoVnXJQGpJBphGvkAF4XI1JGx83Dtlb44wgJ8ZBgOm4qSNOoQIXKv0NO35EwUohtYBMlDJKPRUTwRF93tW7RsfWZGVNi4Eo5k616Tn4ooU3JMXkQA8LZ5zzLllspBVDbyb4GPAmWiw== root@ovzcloud doveadm(root): Debug: Skipping module doveadm_acl_plugin, because dlopen() failed: /usr/lib64/dovecot/doveadm/lib10_doveadm_acl_plugin.so: undefined symbol: acl_user_module (this is usually intentional, so just ignore this message) doveadm(root): Debug: Skipping module doveadm_expire_plugin, because dlopen() failed: /usr/lib64/dovecot/doveadm/lib10_doveadm_expire_plugin.so: undefined symbol: expire_set_deinit (this is usually intentional, so just ignore this message) doveadm(root): Debug: Module loaded: /usr/lib64/dovecot/doveadm/lib10_doveadm_quota_plugin.so doveadm(root): Debug: Module loaded: /usr/lib64/dovecot/doveadm/lib10_doveadm_sieve_plugin.so doveadm(root): Debug: Skipping module doveadm_fts_lucene_plugin, because dlopen() failed: /usr/lib64/dovecot/doveadm/lib20_doveadm_fts_lucene_plugin.so: undefined symbol: lucene_index_iter_deinit (this is usually intentional, so just ignore this message) doveadm(root): Debug: Skipping module doveadm_fts_plugin, because dlopen() failed: /usr/lib64/dovecot/doveadm/lib20_doveadm_fts_plugin.so: undefined symbol: fts_backend_rescan (this is usually intentional, so just ignore this message) doveadm(test1(a)testdomain1.tld): Debug: Added userdb setting: plugin/quota=maildir:storage=512000000 doveadm(test1(a)testdomain1.tld): Debug: Added userdb setting: plugin/quota_rule=*:bytes=512000000 doveadm(test1(a)testdomain1.tld): Debug: Effective uid=997, gid=996, home=/home/vmail/t/e/testdomain1.tld/test1/ doveadm(test1(a)testdomain1.tld): Debug: Quota root: name=storage=512000000 backend=maildir args= doveadm(test1(a)testdomain1.tld): Debug: Quota rule: root=storage=512000000 mailbox=* bytes=512000000 messages=0 doveadm(test1(a)testdomain1.tld): Debug: Quota warning: bytes=486400000 (95%) messages=0 reverse=no command=quota-warning 95 test1(a)testdomain1.tld doveadm(test1(a)testdomain1.tld): Debug: Quota warning: bytes=409600000 (80%) messages=0 reverse=no command=quota-warning 80 test1(a)testdomain1.tld doveadm(test1(a)testdomain1.tld): Debug: Quota grace: root=storage=512000000 bytes=25600000 (5%) doveadm(test1(a)testdomain1.tld): Debug: Namespace inbox: type=private, prefix=INBOX., sep=., inbox=yes, hidden=no, list=yes, subscriptions=yes location=maildir:/home/vmail/t/e/testdomain1.tld/test1/ doveadm(test1(a)testdomain1.tld): Debug: maildir++: root=/home/vmail/t/e/testdomain1.tld/test1, index=, indexpvt=, control=, inbox=/home/vmail/t/e/testdomain1.tld/test1, alt= doveadm(test1(a)testdomain1.tld): Debug: Namespace : type=private, prefix=, sep=, inbox=no, hidden=yes, list=no, subscriptions=no location=fail::LAYOUT=none doveadm(test1(a)testdomain1.tld): Debug: none: root=, index=, indexpvt=, control=, inbox=, alt= Quota name Type Value Limit % storage=512000000 STORAGE 0 500000 0 storage=512000000 MESSAGE 0 -

[patch] TLS Handshake failures can crash imap-login
by Hanno Böck 27 Apr '15

27 Apr '15

Hi, I tracked down a tricky bug in dovecot that can cause the imap-login and pop3-login processes to crash on handshake failures. This can be tested by disabling SSLv3 in the dovecot config (ssl_protocols = !SSLv2 !SSLv3) and trying to connect with openssl and forced sslv3 (openssl s_client -ssl3 -connect localhost:995). This would cause a crash. What was going on is this: In ssl-proxy-openssl.c in line 545 in the function ssl_step() the function ssl_handshake() is called. There SSL_accept() is called. If SSL_accept failes - because a client sent an invalid packet or something the server doesn't support or any other reason - ssl_handle_error() will be called. ssl_handle_error() will call ssl_proxy_destroy(). ssl_proxy_destroy() will then call ssl_proxy_flush(). And ssl_proxy_flush will call ssl_step() again. Here we have a loop. Now when SSL_accept() gets called again on the same context this is an invalid state for OpenSSL and it crashes. What to do? In essence, if ssl_proxy_destroy is called it shouldn't try to finish the handshake if the handshake hasn't even started due to an error. This can be done by a simple if check, see attached patch. I think this should do it. I have seen that a bug that is probably rootet in this has been posted here before regarding ssl3-disabled configs: http://dovecot.org/pipermail/dovecot/2015-March/100188.html cu, -- Hanno Böck http://hboeck.de/ mail/jabber: hanno(a)hboeck.de GPG: BBB51E42

Using Identities to send Emails, question on Email Storage
by Kevin Laurie 27 Apr '15

27 Apr '15

hi, i was wondering that when sending mail with a different identity(bob(a)mydomain.com using help(a)mydomain.com identity), why does it not copy the message to help(a)mydomain.com(Sent box). instead it only shows it on bob(a)mydomain.com(Sent box). appreciate if someone could advise. could someone advise how to fix this as i would like to see the message in help(a)mydomain.com(SentBox) too. thanks kevin

prefetch not working (for me) on ldap user backend
by Hector M. Jacas 26 Apr '15

26 Apr '15

Dear Sir, I'm having problems with the implementation of prefetch userdb. Following the directives from the site (http://wiki2.dovecot.org/UserDatabase/Prefetch) I am unable to avoid the second search to the user backend (ldap). Could give me any advice or tips to achieve my goal? Thanks a lot, Hector M.
