Dovecot lmtp support for SMTPUTF8
by Igor Colombi 16 Sep '16

Hello, I'm using dovecot lmtp with Postfix. I'm enabling SMTPUTF8 (EAI), but when Postfix (v 3.1.2) tries to deliver the message to dovecot-lmtp it receive this error: status=bounced (SMTPUTF8 is required, but was not offered by host dlvmx.espsrv.net[private/dovecot-lmtp] I'm not sure if Dovecot lda and lmpt support EAI and how can I enable it. I've just found and old thread: http://www.dovecot.org/list/dovecot/2013-January/087756.html Thanks for your help. -- Igor Colombi

pop3 deleted count
by Dave 16 Sep '16

16 Sep '16

On pop3 logout, we're seeing log lines where the deleted count is blank (using default pop3_logout_format), so "del=%d/%m" is displaying in the logs as: "del=/1186" for example. In src/pop3/pop3-client.c:552: tab[4].value = client->delete_success ? dec2str(client->deleted_count) : 0; Shouldn't this be: tab[4].value = client->delete_success ? dec2str(client->deleted_count) : "0"; (very minor bug) -- Dave

dovecot-keywords and mbox
by Anton Yuzhaninov 15 Sep '16

15 Sep '16

Hello, With Maildir++ it is possible to store list of IMAP message keyworkds (tags in Thunderbird) on server in dovecot-keywords file. Is it possible the same with mbox mailboxes? My mbox directory contains .subscriptions file, but no .dovecot-keywords file. -- WBR, Anton Yuzhaninov

Hello Timo, from the maintainer of the OpenCSW package I got the below answer. As the newly build package yields another different commit hash (which I cannot find on GitHub too), I would ask, if you are sure that the commit hash-output in 'doveconf -n' is generated correctly?

How to obtain a "non-stripped" executable for producing a usable core-dump
by Ben Johnson 14 Sep '16

14 Sep '16

Hello, I'm attempting to capture a core-dump file, and gdb reports warning: core file may not match specified executable file. And only after installing "dovecot-dbg" on my system (Ubuntu 16.04 LTS) does gdb report further warning: the debug information found in "/lib64/ld-2.23.so" does not match "/lib64/ld-linux-x86-64.so.2" (CRC mismatch). It took some searching the internet to realize that both messages are likely the result of having a "stripped" executable: # file /usr/lib/dovecot/dovecot-lda /usr/lib/dovecot/dovecot-lda: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.32, BuildID[sha1]=49c9c607c304a5c853c05a4ccb9e4b995f185ac4, stripped So, how best I am I to obtain a "non-stripped" dovecot-lda executable? Must I forego my distro's repositories and download the dovecot source, compiling every executable and all plugins "from scratch", in order to obtain a useful core-dump file? Perhaps the bug report instructions at http://www.dovecot.org/bugreport.html should mention "stripped" executables and how to avoid them. Perhaps I am simply ignorant, but if that is the case, there is little to no hope for the "average user" where submitting bug reports is concerned. Any guidance would be most appreciated. Thanks in advance, -Ben

Limit replication to one user
by Arne Hoffmann 14 Sep '16

14 Sep '16

Hello, we have a setup here where the main (and only important) feature of the IMAP server is the public folder. Two Dovecot instances are running in a active/passive cluster and mailstorage should be replicated between the two. Since there is a race condition when using public namespaces (locking on user level and not on mailbox level) I had the intention of limiting the replication to one user. I read somewhere that dsync is replicating all the users the command "doveadm user '*'" shows. And the command only shows *one* user because I have modified the iterate_query: ,----[/etc/dovecot/mysql.conf] | iterate_query = SELECT username AS user FROM mailbox WHERE username = 'data_replication(a)example.com' `---- root [~]# doveadm user '*' data_replication(a)example.com root [~]# So, why does Dovecot still replicate mails from other users inboxes? And why does doveadm replicator still show other users? root [~]# doveadm replicator status '*' username priority fast sync full sync success sync failed data_replication(a)example.com none 00:57:14 01:13:21 00:57:12 - arne.hoffmann(a)example.com none 00:20:04 00:31:40 00:20:02 - root [~]# [I removed some whitespace to keep line length in check] Any explanation of this behavior would be just awesome.

As the initial performance is bad it scales pretty quickly with space used. So it handles maildir storage very well. The latency is a little high but with indexes there is no problem. It works as NFS storage with unlimited space (8EB) and you pay for what you use. So it turns out to be very cost effective as you do not have to worry about reserving space. For better performance you can keep indexes on ephermal storage or EBS, which both have much lower access times. As for 'elastic cloud type hosting' EFS store can be used by thousands of instances in multiple AWS AZs at the same time, so it looks like it is somehow optimized.

Sieve filtering SPAM and redirect
by Andre Luiz Paiz 12 Sep '16

12 Sep '16

Hi every body. I'm having difficulties to setup my filters correctly and I really need some help. This is my environment: Mail that is received on the system passes through a sieve_before script that checks the message header for SPAM tag and store it into the "Junk" folder. If no spam tag is found, mail goes to inbox. My horde webmail is integrated with sieve, so this allow users to create their own scripts to store mail in other folders or forward them to external accounts. And this are the problems I'm having: 1 - When users create a forward filter to redirect to external mail, mail that is stored inside the Junk folder are not forwarded; 2 - If I insert a "keep" parameter inside the sieve_before script to keep processing the rules, the mail is forwarded, but becomes duplicated and stored inside the inbox or other folders, if the user has more filters. 3 - If I move my sieve_before script to sieve_after, the same thing happened, one copy is stored on the user selected folder (inbox or filtered), including mail marked as SPAM. My needs are: I need to separate SPAM and HAM e-mail before users intervention (so I need sieve_before). But this SPAM e-mail has to be forwarded if a forward filter is created. Is it possible to use a sieve_after script that moves (instead of copy) the user mail marked as SPAM to the Junk folder even if it was stored in a different folder? Is that possible? Thanks a lot.

Use of obox2 and AWS S3
by Raymond Sellars 11 Sep '16

11 Sep '16

Hi Has anyone used or is using dovecot obox and S3 storage? I see very little chatter or documentation on it. Interested in how mature it is and technical items such as high availability and region replication. I'm guessing that multiple updates to a S3 mailbox is mitigated via the standard dovecot pattern of Director pointing multiple user sessions to a single/common dovecot node. And for disaster recovery - that's out of scope of dovecot and more reliant on S3 replication? Any one running a dovecot solution within AWS in general? Interested in best practice for the storage layer. Although NFS is possible its not really optimised for elastic cloud type hosting. Thanks Raymond

sieve - find in header
by Hajo Locke 09 Sep '16

09 Sep '16

Hello list, have a problem with sieve script. I want to perform an action if an arbitrary headerline contains a defined string. I tried with regex: if header :regex [".*"] ["searchstri.*"] { fileinto "junk"; } This is not working because regex is only used in 2nd argument ["searchstri.*"] In 1st argument [".*"] no regex is used, sieve expects just plain string. Something like this would work, if "x-myheader" contains "searchstring": if header :regex ["x-myheader"] ["searchstri.*"].... How to solve this case and find a string in arbitrary/unknown headerline? Thanks, Hajo

OK, the origin of your problem becomes clearer. You can hardcode these paths into the executables by doing something like env CFLAGS='-I/my'ssl/include' \ LDFLAGS='-L/your/ssl/lib -Wl,-rpath,/my/ssl/lib' \ configure ... I use this myself (except the -Wl part since these libs are symlinked to my shared library path).

I don't have that problem -- I use configure to tell dovecot where to find my self-compiled openssl, and the resulting executables load from where I want. Joseph Tam <jtam.home(a)gmail.com>

This is my quota backends configuration: plugin { quota = maildir:UserQuota quota2 = dict:Quota Usage::noenforcing:proxy::sqlquota } dict { sqlquota = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } I found that if I comment the line “quota2 = dict:…” doveadm quota recalc works fine. I have two quota backends because with dict I can store everybody's current quota usage in a SQL database for fast retrieving (like quota_clone plugin but I cannot switch to it immediately).

You can also affect where shared libraries are loaded using the LD_LIBRARY_PATH environment variable. Try adding LD_LIBARY_PATH=/location/of/libdir; export LD_LIBARY_PATH to your service boot scripts. Joseph Tam <jtam.home(a)gmail.com>

It's fine for a temporary working around problems (like this one, so you're absolutely right :-) However, no program should require that for regular use because you never know exactly if somebody in the chain of executed code removes certain environment variables. And also the opposite way, if Dovecot runs external programs, those might not play well with an existing LD_LIBARY_PATH and incompatible SSL libraries. For every program I compile myself, I link it against my custom OpenSSL library (always newest version; distributions usually tend to stick with a specific version and only apply security fixes). For most packages (eg, Exim, Apache HTTP, BIND, INN, OpenSSH, Mutt, wget etc.) it pretty straightforward. Even if not, usually I can find a quick solution myself. Dovecot is the only package I know of where there are like a thousand places to put additional libs in the Makefile.am files, but most of them are totally ignored by configure. And even if I modify the Makefile files after configure, again most of the additional options get ignored. Never seen it that complicated. As Dovecot is my favorite IMAP daemon, there's no way I'm giving up. :-) I'm totally confident that the developers will find a good solution. And I'm happy to test every patch they come up with. Greetings, Andreas

Cannot subscribe to Public mailbox
by MI 04 Sep '16

04 Sep '16

I'm trying to set up a Public mailbox, but when I try to subscribe to it in Thunderbird, nothing happens: it doesn't appear as a folder, and when I go back to the Subscribe window, it is unchecked again. I use postfix local dlivery, which created a Maildir when a mail arrived for this mailbox: /home/others/sharedmail/Maildir/{cur,new,tmp} (sharedmail is a system user so that Postfix can deliver the mail; it doesn't have a login shell or a password) To make sure it is not a simple filesystem permissions problem, I did "chmod -R a+rwX Maildir/" This is my current config ( I tried to keep it short by leaving only what might be relevant ): # dovecot -n # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-4-amd64 x86_64 Debian 7.9 ... mail_location = maildir:~/Maildir namespace { list = yes location = maildir:/home/others/sharedmail/Maildir prefix = Public. separator = . subscriptions = no type = public } namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox ... ... } prefix = separator = . } passdb { driver = pam } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = " imap" service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } } userdb { driver = passwd } Also, I'm not sure about the difference between type=public and type=shared. But anyway, I tried both with the same result.

Alternate mail store of few users is disparaged unexpectedly
by Prakash Autade 02 Sep '16

02 Sep '16

Hello, We are using dovecot with mdbox and ALT store on S3(Simple Storage System). We export the mail_location=mdbox:/<user-mailstore>/mdbox:ALT=/altmailstore/<user-mailstore>/mdbox of user in extra parameters. Today, alternate mail store of few users is disparaged unexpectedly which resulted in mail loss. We are unable to trace out why and when the alternate store is disparaged. Our hypothesis is, the folder is removed during doveadm altmove. We want to prevent this in future. It will be great if someone helps to identify the root cause. Dovecot version: 2.2.19 # dovecot -n # 2.2.19: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-573.el6.x86_64 x86_64 CentOS Linux release 6.0 (Final) auth_mechanisms = plain login auth_verbose_passwords = plain disable_plaintext_auth = no mail_fsync = always mail_gid = 65111 mail_location = maildir:~/Maildir mail_nfs_index = yes mail_nfs_storage = yes mail_plugins = " quota" mail_uid = 65111 mdbox_rotate_interval = 1 days mdbox_rotate_size = 20 M mmap_disable = yes namespace inbox { inbox = yes location = mailbox Drafts { auto = create special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Items" { auto = create } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { auto = create special_use = \Trash } mailbox chat { auto = create } prefix = INBOX. separator = . type = private } plugin { mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename mail_log_fields = uid box msgid size } ssl_cert = </conf/server/server.crt ssl_key = </conf/server/server.key -- Sincerely, Prakash P.

Dovecot 2.2.25 fails on SSL
by Andreas M. Kirchwitz 02 Sep '16

02 Sep '16

Dear Dovecot developers! This problem already existed some years ago, has been fixed, and now it's there again in Dovecot 2.2.25 (2.2.24 was fine). I'm running CentOS 6 with a custom OpenSSL installation in /usr/local/ssl Therefore, Dovecot is configured like this: env SSL_CFLAGS="-I/usr/local/ssl/include" SSL_LIBS="-L/usr/local/ssl/lib -Wl,-R/usr/local/ssl/lib -lcrypto -lssl" ./configure --prefix=/usr/local/Dovecot-2.2.25 --with-ssl=openssl --with-ssldir=/usr/local/Dovecot-2.2.25/etc/dovecot/certs With "pkg-config", the same options for SSL are provided. "make" and "make install" run just fine, and the daemon starts without any errors. However, if a user connects on port 993 (IMAPS), Dovecot logs this failure message to syslog: Jul 4 01:08:43 myhost dovecot: ssl-params: Fatal: Couldn't load required plugin /usr/local/Dovecot-2.2.25/lib/dovecot/libssl_iostream_openssl.so: dlopen() failed: libcrypto.so.1.0.0: cannot open shared object file: No such file or directory Jul 4 01:08:43 myhost dovecot: ssl-params: Error: child process failed with status 22784 ldd /usr/local/Dovecot-2.2.25/lib/dovecot/libssl_iostream_openssl.so linux-gate.so.1 => (0x00e8c000) libcrypto.so.1.0.0 => not found libssl.so.1.0.0 => not found librt.so.1 => /lib/librt.so.1 (0x00be4000) libc.so.6 => /lib/libc.so.6 (0x001a6000) libpthread.so.0 => /lib/libpthread.so.0 (0x003e4000) /lib/ld-linux.so.2 (0x007e7000) ldd /usr/local/Dovecot-2.2.25/lib/dovecot/libdcrypt_openssl.so linux-gate.so.1 => (0x00dca000) libcrypto.so.1.0.0 => not found libssl.so.1.0.0 => not found librt.so.1 => /lib/librt.so.1 (0x00a7a000) libc.so.6 => /lib/libc.so.6 (0x00160000) libpthread.so.0 => /lib/libpthread.so.0 (0x0072f000) /lib/ld-linux.so.2 (0x00560000) When comparing to Dovecot 2.2.24: ldd /usr/local/Dovecot-2.2.24/lib/dovecot/libssl_iostream_openssl.so linux-gate.so.1 => (0x0073d000) libcrypto.so.1.0.0 => /usr/local/ssl/lib/libcrypto.so.1.0.0 (0x00b04000) libssl.so.1.0.0 => /usr/local/ssl/lib/libssl.so.1.0.0 (0x0044a000) librt.so.1 => /lib/librt.so.1 (0x00a60000) libc.so.6 => /lib/libc.so.6 (0x001e5000) libdl.so.2 => /lib/libdl.so.2 (0x003a9000) libpthread.so.0 => /lib/libpthread.so.0 (0x009d0000) /lib/ld-linux.so.2 (0x00d77000) There's no libdcrypt_openssl.so in Dovecot 2.2.24, so I guess with the newly introduced dcrypt stuff something with SSL went wrong. Would be great if that could be fixed so that SSL works again. Thanks a lot in advance ... Andreas

Force SSL/TLS and client certificate checking only for connections from Internet
by Konstantin Khomoutov 02 Sep '16

02 Sep '16

(Please CC me if possible.) I have Dovecot 2.2.13 (shipped with Debian 8 "Jessie") serving IMAP for a small organization. It's connected both to the Internet and to that organization LAN. I'd like to have Dovecot has rather tight security requirements for connections made from the Internet and reasonably laxed requirements for the LAN clients. Due to Dovecot authenticating users against a LDAP database which is also used for logging into the users' machines, we have to use somewhat weak passwords (randomly generated but short) for most users. Because of this I want to: * Mandate the usage of TLS for the connections made from Internet; * Require the clients to present their SSL certificates, and * Verify the validity of these certificates. The certificates are issued by our own CA, so it's not a problem to verify them. The first iteration was to set ssl = required and disable_plaintext_auth = yes which I then overrode with a "remote" section for LAN connections: remote 192.168.0.0/16 { disable_plaintext_auth = no ssl = yes } The next iteration was to actually enable verification of the client certificates. I have set the "ssl_ca" variable appropriately, then ssl_require_crl = yes ssl_verify_client_cert = yes and auth_ssl_require_client_cert = yes Then I went on and attempted to override the latter two settings for the LAN clients by appending them to my special "remote" section to it read: remote 192.168.0.0/16 { disable_plaintext_auth = no ssl = yes ssl_verify_client_cert = no auth_ssl_require_client_cert = no } But after restart Dovecot complained that I cannot use the "auth_ssl_require_client_cert" setting in a "remote" section. I have removed it in the hope that still having ssl_verify_client_cert = no there would inhibit SSL certificate checks for the LAN clients but apparently it did not. So, to recap: * I need to have tight TLS settings for the clients connecting from the Internet: - TLS is required; - The client must present a valid certificate (issued by a CA we control). * LAN clients should use relaxed security settings: TLS is okay but that's all. How do I go about setting this? (On a side note, I can supposedly get away installing stunnel and making it proxy IMAP and IMAPS connections to Dovecot -- at least from the documentation, it appears stunnel supports IMAP+STARTTLS, -- but I would rather have all this handled solely by Dovecot.)

Debian Jessie comes with systemd so you really should not use initscript anymore but switch to systemd for starting dovecot. There is systemd service description file available for you in case your vendor does not provide it in the package: https://github.com/dovecot/core/blob/master/dovecot.service.in Sami

Dsync config help
by Jean-Luc Wasmer 01 Sep '16

Hi, I’m having a hard time with the http://wiki2.dovecot.org/Replication page. - for a master-master setup, does the configuration need to be mirrored on both masters? - after aggregating unrelated sections of the wiki page, there seems to be 3 different values for “mail_replica": - "remote”: for SSH - “remoteprefix": for SSH wrapper - “tcp”: for TCP connection using the Doveadm protocol Is this correct? - what’s the purpose of the replicator VS aggregator VS doveadm services? Who talks to who? Where can I find documentation about their configuration (i.e. not examples) - most examples are for a single vmail user setup… what should be done when using system accounts? Thanks, Jean-Luc

autoexpunge clarification
by Michael Fox 01 Sep '16

01 Sep '16

I'm trying to understand autoexpunge, but the documentation is just not clear. Hopefully, someone can clear up a few questions. http://wiki.dovecot.org/MailboxSettings says the following: autoexpunge=<time>: (v2.2.20+) Automatically at user deinitialization expunge all mails in this mailbox whose saved-timestamp is older than <time> (e.g. autoexpunge=30d). This removes the need for expire plugin <http://wiki.dovecot.org/Plugins/Expire> if you don't care that the expunging may not always happen in time. What does "at user deinitialization" mean? What does "if you don't care that the expunging may not always happen in time" mean? I read the sub-bullets but they just aren't clear. When exactly does autoexpunge occur? Thanks, Michael

Help setting up IMAP account in Outlook 2016
by Spiro Angeli 01 Sep '16

01 Sep '16

Hi, I need help setting up mail clients for my email accounts running on dovecot ver 2.2.18 on CentOS release 6.8 (Final) and Plesk Web Admin Edition in Italian. For better reading I posted a forum thread where you can get all detail info: Help setting up IMAP account in Outlook 2016 Forum link: http://www.emailquestions.com/threads/help-setting-up-imap-account-in-outloo k-2016.13439 I was advised to " ask dovecot list for help with the IMAP server. " So I did and a user kindly suggested me to customize "15-mailboxes.conf " file. I have some technical questions I need to ask. Hope someone knows the answers. As Plesk continuously updates itself and manages most of the server the majority of CentOS fils report this lines on top of each file: ## ## Authentication for Plesk mail users. ## # PLEASE DON'T EDIT ANYTHING IN THIS FILE! ANY CHANGES WILL BE LOST ON UPGRADE. So if I customize this "15-mailboxes.conf " I need to make sure that Plesk does not overwrite. Also I need to make sure that it gets updated if Dovecot changes in its settings. So, my first question is: how do I manage to keep this "15-mailboxes.conf " file updatable by OS (when I update system) but at the same time retain customizations upon system updates? Second question has to do with customization: Please consult attachment for this question a. I wish to see existing server folders (Draft, Sent, Spam, Trash) on my MS Outlook mail client software only in Italian and not in English. What should I do? Roundcube displays them in Italian. AquaMail (on Android) displays them in Italian. b. I was told to solve this server wise and not mail box per mailbox. Is this correct? c. Can you please share a complete customized code, for my needs, for this "15-mailboxes.conf " so I can learn from it? Thank you, Spiro

ACL List uses wrong namespace for permissions
by Harald Leithner 31 Aug '16

31 Aug '16

Hi, I'm using dovecot 2.2.devel (11c704a) with lazyexpunge and shared Mailboxes, this seams to work since the latest patch. There is only one problem creating the correct dovecot-acl-list, if I login as the normal user that has set permissions for another user everything is ok. If I login with the same user but with a modified roundcube that uses the #EXPUNGED Namespace as root, dovecot overrides the correct dovecot-acl-list with an empty version. I think this is the most interesting part of the log: 2016-04-26T16:49:26+02:00 mailstore1 dovecot: imap(user(a)company.at): Debug: fs: root=/srv/storage1/vmail/company/628, index=, indexpvt=, control=, inbox=, alt= 2016-04-26T16:49:26+02:00 mailstore1 dovecot: imap(user(a)company.at): Debug: acl: initializing backend with data: vfile 2016-04-26T16:49:26+02:00 mailstore1 dovecot: imap(user(a)company.at): Debug: acl: acl username = user(a)company.at 2016-04-26T16:49:26+02:00 mailstore1 dovecot: imap(user(a)company.at): Debug: acl: owner = 1 2016-04-26T16:49:26+02:00 mailstore1 dovecot: imap(user(a)company.at): Debug: acl vfile: Global ACLs disabled 2016-04-26T16:49:26+02:00 mailstore1 dovecot: imap(user(a)company.at): Debug: Namespace : type=private, prefix=#EXPUNGED/, sep=, inbox=no, hidden=yes, list=no, subscriptions=no location=mdbox:/srv/storage1/vmail/company/628:MAILBOXDIR=expunged 2016-04-26T16:49:26+02:00 mailstore1 dovecot: imap(user(a)company.at): Debug: fs: root=/srv/storage1/vmail/company/628, index=, indexpvt=, control=, inbox=, alt= 2016-04-26T16:49:26+02:00 mailstore1 dovecot: imap(user(a)company.at): Debug: acl: initializing backend with data: vfile 2016-04-26T16:49:26+02:00 mailstore1 dovecot: imap(user(a)company.at): Debug: acl: acl username = user(a)company.at 2016-04-26T16:49:26+02:00 mailstore1 dovecot: imap(user(a)company.at): Debug: acl: owner = 1 2016-04-26T16:49:26+02:00 mailstore1 dovecot: imap(user(a)company.at): Debug: acl vfile: Global ACLs disabled 2016-04-26T16:49:26+02:00 mailstore1 dovecot: imap(user(a)company.at): Debug: Namespace : type=shared, prefix=#Users/%u/, sep=/, inbox=no, hidden=no, list=children, subscriptions=yes location=mdbox:/srv/storage1/vmail%h 2016-04-26T16:49:26+02:00 mailstore1 dovecot: imap(user(a)company.at): Debug: shared: root=/var/run/dovecot, index=, indexpvt=, control=, inbox=, alt= 2016-04-26T16:49:26+02:00 mailstore1 dovecot: imap(user(a)company.at): Debug: acl vfile: file /srv/storage1/vmail/company/628/mailboxes/dovecot-acl not found 2016-04-26T16:49:26+02:00 mailstore1 dovecot: imap(user(a)company.at): Debug: Namespace : Using permissions from /srv/storage1/vmail/company/628: mode=0700 gid=default 2016-04-26T16:49:26+02:00 mailstore1 dovecot: imap(user(a)company.at): Debug: acl vfile: file /srv/storage1/vmail/company/628/mailboxes/Drafts/dbox-Mails/dovecot-acl not found 2016-04-26T16:49:26+02:00 mailstore1 dovecot: imap(user(a)company.at): Debug: acl vfile: file /srv/storage1/vmail/company/628/expunged/dovecot-acl not found 2016-04-26T16:49:26+02:00 mailstore1 dovecot: imap(user(a)company.at): Debug: Namespace #EXPUNGED/: Using permissions from /srv/storage1/vmail/company/628: mode=0700 gid=default 2016-04-26T16:49:26+02:00 mailstore1 dovecot: imap(user(a)company.at): Debug: acl vfile: file /srv/storage1/vmail/company/628/expunged/INBOX/dbox-Mails/dovecot-acl not found 2016-04-26T16:49:26+02:00 mailstore1 dovecot: imap(user(a)company.at): Debug: acl vfile: file /srv/storage1/vmail/company/628/expunged/INBOX/test/dbox-Mails/dovecot-acl not found 2016-04-26T16:49:26+02:00 mailstore1 dovecot: imap(user(a)company.at): Debug: acl vfile: reading file /srv/storage1/vmail/company/628/mailboxes/INBOX/dbox-Mails/dovecot-acl 2016-04-26T16:49:26+02:00 mailstore1 dovecot: imap(user(a)company.at): Logged out in=178 out=870 2016-04-26T16:49:26+02:00 mailstore1 dovecot: imap(user(a)company.at): Logged out in=315 out=27172 regards, -- Harald Leithner ITronic Wiedner Hauptstraße 120/5.1, 1050 Wien, Austria Tel: +43-1-545 0 604 Mobil: +43-699-123 78 4 78 Mail: leithner(a)itronic.at | itronic.at

Automatic purging of old email in all mailboxes
by Scott W. Sander 30 Aug '16

30 Aug '16

I am using a postfix + Dovecot server as a test mail server for which some applications in our test environment use as a target to deliver email so that our real endusers don't receive messages from our test servers. A few of the mailboxes in Dovecot receive hundreds of emails per day. I'd like to automatically remove all emails in all mailboxes and mailbox folders that were received more than 90 days prior to the received date. As I'm a novice Dovecot administrator, I'm not exactly sure what the best way to accomplish this is, but I've started looking at the "doveadm expunge" command. I figure I could create a cron job that calls this command with the -A switch and that has a search query that finds all emails older than 90 days. I'm aware that I can test my query by using the "doveadm search" command. The problem is that when I do any sort of search query with that command (e.g. "doveadm search -A NEW"), I receive the following error messages: Error: User listing returned failure doveadm: Error: Failed to iterate through some users I've searched for help with this error, but most of the guidance I'm seeing refers to making sure that dovecot-sql is configured correctly; however, I'm using "passwd-file" for the passdb and not a true database.

Sub addressing delimiters
by Kurt Fitzner 30 Aug '16

30 Aug '16

Hello, There is a disconnect between the way Postfix handles recipient_delimiter and the way Dovecot handles it. For Postfix, it is a set of delimiters that can each individually be used to separate the address from the . In Dovecot, having multiple characters in recipient_delimiters simply makes it a multi-character single delimiter. For my purposes, the Postfix method is much more versatile. Extra delimiters can be added without breaking the way users currently have delimiters. I am wondering what the odds are of reconciling the two approaches, hopefully in favour of the Postfix one. Failing a switch to the other behaviour, is it possible to add the Postfix method as an option? Would a patch for either of these be accepted? Thanks, Kurt Fitzner

Move dovecot between servers
by Gandalf Corvotempesta 30 Aug '16

30 Aug '16

Hi to all I have a very old dovecot server (1.2.15) with about 195GB used and 1081 email accounts. I have to move this server to another one with contextual dovecot upgrade. Anyone did this before? Any advice? Obviously, existing emails *must not* be downloaded twice by existing clients (outlook, thunderbird, ...) I have no access to customer's clients, only to my server.

sieve-filter with duplicate-extension
by hendrik＠luecke-tieke.de 26 Aug '16

26 Aug '16

Hi, i have imported a mailbox twice (accentially). Now i thought, it might be a valid approach to simply use a custom sieve rule to mark duplicates using the attached ruleset I ran sieve-filter like this: ~# sieve-filter -e -W -v -C -u userxyz(a)example.com /var/vmail/example.com/userxyz/sieve/duplicates.sieve 'INBOX' But sieve-filter complains like this: info: msgid=<1231321313212312312312(a)p3enginer2.emv2.com>: left message in mailbox 'INBOX'. info: message kept in source mailbox. info: filtering: [Sun, 1 May 2011 16:41:46 +0100; 101297 bytes] `Cipo & Baxx, Nike Golf, Strenesse, al...'. roundcube2: line 3: warning: duplicate test: duplicate checking not available in this context. info: msgid=<1123123123123123(a)p3enginer3.emv2.com>: left message in mailbox 'INBOX'. info: message kept in source mailbox. info: filtering: [Sun, 28 Oct 2012 11:32:56 +0100; 1416 bytes] `DenyHosts Report for example.com'. roundcube2: line 3: warning: duplicate test: duplicate checking not available in this context. Is there a way, to refilter an existing mailbox and applying the duplicate extension? Many thanks and best regards, Hendrik

lazy_expunge and public folder
by Arne Hoffmann 26 Aug '16

26 Aug '16

Hi all, I stumbled upon the lazy_expunge plugin and thought that it might be useful in some cases. It works fine if I delete mails from my inbox. But it doesn't do anything if I deleted mails from a public folder (and for the server I am currently working on the public folder is _the_ _main_ _feature_). Does lazy_expunge not work with public folders? Or am I using it wrong? root@imap01 [~]# doveconf -n # 2.2.24 (a82c823): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.13 (7b14904) # OS: Linux 3.16.0-4-amd64 x86_64 Debian 8.5 ext4 auth_debug = yes auth_debug_passwords = yes debug_log_path = /var/log/mail.debug disable_plaintext_auth = no doveadm_password = # hidden, use -P to show it doveadm_port = 22001 mail_debug = yes mail_location = maildir:/var/mail/vmail/%d/%n/Maildir:INBOX=/var/mail/vmail/%d/%n/Maildir mail_plugins = " listescape lazy_expunge notify replication" mail_privileged_group = vmail namespace { location = maildir:/var/mail/vmail/Öffentliche Ordner:INDEXPVT=~/Maildir/Öffentliche Ordner mailbox "Gelöschte Elemente" { auto = subscribe special_use = \Trash } mailbox MirrorServer-Projekt { auto = subscribe } prefix = Öffentliche Ordner/ separator = / subscriptions = no type = public } namespace { hidden = yes list = no location = maildir:~/Maildir/expunged prefix = .EXPUNGED/ separator = / } namespace inbox { inbox = yes location = prefix = separator = / type = private } passdb { args = /etc/dovecot/mysql.conf driver = sql } plugin { lazy_expunge = .EXPUNGED/ mail_replica = tcps:imap02.example.com } protocols = imap service aggregator { fifo_listener replication-notify-fifo { user = vmail } unix_listener replication-notify { user = vmail } } service doveadm { inet_listener { port = 22001 ssl = yes } } service replicator { process_min_avail = 1 unix_listener replicator-doveadm { group = vmail mode = 0660 } } ssl = required ssl_ca = </etc/ssl/os/cert-sub-ca1-and-root-ca.pem ssl_cert = </etc/ssl/os/cert-imap01-example.com.pem ssl_client_ca_file = /etc/ssl/os/cert-all.pem ssl_client_cert = </etc/ssl/os/cert-imap01-example.com.pem ssl_client_key = </etc/ssl/os/key-imap01-example.com.pem ssl_key = </etc/ssl/os/key-imap01-example.com.pem ssl_require_crl = no userdb { args = /etc/dovecot/mysql.conf driver = sql } root@imap01 [~]#

Change dovecot hostname

Possible IMAP IDLE bug in Dovecot 2.2.18 and 2.2.25
by cleber-listas＠inetweb.com.br 24 Aug '16

24 Aug '16

Hello Guys, I guess that I found a bug in Dovecot 2.2.18 and 2.2.25 versions. The problem it's when I try to connect in a Dovecot used a proxy to another e-mail server (in our case it's a Smartermail Server) the DoveCot send a lot of IDLE commands to the destination server. With that, the LOG files grow and grow and grow :( I make a test with 1 connection only and if you see the log file in the same second the dovecot send 25, 40 IDLE commands. But, when I disconnect the client (outlook 2013) the dovecot continue to send the IDLE command for some seconds. If I try to connect directly to Smartermail with Outlook this don't occurrs.

antispam plugin pipe script seems not to be called when it "should be"
by Ben Johnson 23 Aug '16

23 Aug '16

Hello, (Full "doveconf -n" output is at the end of this message.) I'm attempting to recreate a "recipe" I had used successfully for quite some time (in Ubuntu 12.04 LTS), which allowed me to train SpamAssassin's Bayes database when someone dragged an email message from one sub-folder of the account to another. I later tried to re-implement it (in Ubuntu 14.04 LTS), and core-dumps resulted. I posted to this list about it several times, but nobody was ever able to help me solve the problem. I just tried the same (in Ubuntu 16.04 LTS), hoping that the source had evolved since then, and while I don't see a core-dump, the pipe script doesn't seem to be called. I've booby-trapped the pipe script with quite a bit of debugging output, which should be written to a file, but I don't see any indication that the pipe script is ever executed. When logged-in as an IMAP user, and I drag a message from the user's Inbox into the "Spam" folder, I do see the following activity in the syslog: Aug 18 22:12:15 example.com imap: antispam: mailbox_is_unsure(Junk): 0 Aug 18 22:12:15 example.com imap: antispam: mailbox_is_trash(INBOX): 0 Aug 18 22:12:15 example.com imap: antispam: mailbox_is_trash(Junk): 0 Aug 18 22:12:15 example.com imap: antispam: mail copy: from trash: 0, to trash: 0 Aug 18 22:12:15 example.com imap: antispam: mailbox_is_spam(INBOX): 0 Aug 18 22:12:15 example.com imap: antispam: mailbox_is_spam(Junk): 1 Aug 18 22:12:15 example.com imap: antispam: mailbox_is_unsure(INBOX): 0 Aug 18 22:12:15 example.com imap: antispam: mail copy: src spam: 0, dst spam: 1, src unsure: 0 Aug 18 22:12:15 example.com imap: antispam: running mailtrain backend program /bin/bash Aug 18 22:12:15 example.com imap: antispam: running mailtrain backend program /bin/bash Aug 18 22:12:15 example.com imap: antispam: running mailtrain backend program parameter 1 /usr/local/bin/sa-learn-pipe.sh Aug 18 22:12:15 example.com imap: antispam: running mailtrain backend program parameter 2 --spam But the piped message is never delivered to the target mailbox.

Postfix uses the filename you provide as name for the db file, so running it against symlinks does follow the symlink, but it uses the symlink name as what it uses to create the .db file. You can test this by creating file and doing symlink for it and running postmap against the symlink. You'll see that it will create symlink-name.db file instead of file.db. Aki Tuomi Dovecot oy

Oh yeah, right, LMTP. I don't run LMTP myself, but I suspect the hostname is mapped from the IP of the LMTP listening interface (using /etc/hosts or DNS). Maybe you can change the IP of your listening interface to match mail.domain.test and firewall it off if that IP is public facing. >From reading the code, I can't quite grok how LMTP derives the host label, but as a last resort, you can patch at src/lmtp/commands.c in client_get_added_headers().

specifying elliptic curve

Hi, I've noticed that Dovecot is using per default the elliptic curve sect571r1. Because not all clients might support sect571r1, I would like to set the elliptic curve manually. Is that possible? -Ihsan -- ihsan(a)dogan.ch http://blog.dogan.ch/

Crash on opening mailbox
by Ladislav Laska 22 Aug '16

22 Aug '16

Hi! I'm currently experiencing a crash of dovecot 2.2.25 on Gentoo, upon opening mailbox. The crash only triggers on opening inbox, other mailboxes seem to work fine. It happens every time, and can be reproduced on request. I also briefly tried 2.2.19, and it behaves the same. The bug seems to be triggered by some mail, as I encountered it previously and fixed by removing some spam. I guess it might be malformed header of some kind. I can open the mailbox locally using mutt, but fail to do so remotely (using mutt or K-9 mail on android). Unforunately, I haven't been able to isolate the specific mail, as when I create a new mailbox, dovecot refuses to open it: [CANNOT] Mailbox isn't a valid mbox file (0.000 + 0.000 secs). I'm not really sure what's going on and will investigate further once I find some time to do so. I also experienced a similar problem on opening a specific mail, but it's much harder to reproduce and I currently don't have an example. The crash looks very similar, and only happens on first attempt to open a specific mail, it always works later on. I'm attaching a stack trace and dovecot -n. I'm also willing to send the binary and core dump, but not publicly, as I'm not eager to share whatever's inside with the whole world. Other than what I mentioned, I'm running pretty standard setup, with postfix on Gentoo x86_64, ext4 fs, quota and disk space is plentiful. The delivery agent is dovecot itself, in postfix/main.cf I have: mailbox_command = /usr/libexec/dovecot/deliver I'm using sieve script to file my mail, but the problem manifested even before when I was still using procmail to deliver my mail (I migrated because I had doubts about procmail and dovecot lock cooperation) I'll keep my mailbox corrupted for a few more days, and access the mail only locally, hoping to test a potential fix. Let me know if you need any more info/experimentation. Also, if you know a good way to find the mail that causes the trouble out of the core, let me know, I'd be glad to forward it for testing. Thanks and I hope we can find (and fix) the problem! -- S pozdravem Ladislav Láska <laska(a)kam.mff.cuni.cz> Katedra Aplikované Matematiky, MFF UK tel.: +420 739 464 167

LMTP doing passdb queries ?
by Peter Mogensen 22 Aug '16

22 Aug '16

Hi, I can see dovecot is doing a passdb query when handling the LMTP RCPT command. That's kinda unexpected for me. I would have thought it only did a userdb lookup. I have disabled lmtp_proxy to be sure it didn't do a passdb lookup to check the proxy field. Is this expected? Doesn't the LDA only do userdb lookups? /Peter

Catch-all with LMTP and Postfix

Hidy-ho, I'm having a difficult time getting catch-all working when using Dovecot LMTP.

Field Return-Path contains twice the domain
by Quaquaraquà 22 Aug '16

22 Aug '16

Dear exim & dovecot users, posting on both mailing lists as I am not sure who has the ultimate responsability for this field. I am trying to set up a mail server for multiple domains in my VPS. So I managed to set up the authentication through a dovecot authenticator, which relies to a sqlite database. I would like that, from the database perspective, a query has, as input parameters, both the username and the domain to check the password. For this purpose, I am requesting that the SMTP account is in the full form username(a)domain.com. When forwarded to the dovecot authenticator, I can extract the user with %n and %d. This works, but it has a utter drawback: emails are sent repeating twice the domain in the Return-Path field, e.g. : Return-Path: <"user(a)domain.net"@domain.net> Subject: Re: Hello To: nuquaquaraqua(a)gmail.com From: user <user(a)domain.net> How do I properly fix the field Return-Path now? dovecot --version: 2.2.25 (7be1766) Exim version 4.87 #1 built 28-Jul-2016 18:38:04 Kind regards, Quaquaraqua

Occasional error from TB when selecting a dovecot's shared mbox: "Unable to open the summary file for [shared]" "Perhaps there was an error on disk, or the full path is too long." The server's disk is clear, and the longest full path is [a-zA-Z\/\.]{46}. The error occurs occasionally.

What might cause messages delivered with dovecot-lda to be "invisible" to IMAP clients?
by Ben Johnson 19 Aug '16

19 Aug '16

Hello! I'm attempting to use dovecot-lda, and for whatever reason, messages that I send with it are not visible in my IMAP client. $ dovecot --version 2.2.22 (fe789d2) (Full "doveconf -n" output is at the bottom of this message!) Here's the the sequence of commands that I'm using: # su vmail $ echo 'This is a test message.' > /tmp/test.txt $ stat /tmp/test.txt File: '/tmp/test.txt' Size: 24 Blocks: 8 IO Block: 4096 regular file Device: fd01h/64769d Inode: 783925 Links: 2 Access: (0664/-rw-rw-r--) Uid: ( 5000/ vmail) Gid: ( 5000/ vmail) Access: 2016-08-18 20:49:38.419011552 -0400 Modify: 2016-08-18 20:49:07.178995015 -0400 Change: 2016-08-18 20:49:38.191011425 -0400 Birth: - $ /usr/lib/dovecot/dovecot-lda -d "test(a)example.com" -p "/tmp/test.txt" When I do this, the destination mailbox acts like there's a new message (I'm using Thunderbird, and the mailbox is highlighted in blue and bolded, which is the "new mail" behavior in this client). But when I "check my inbox", i.e., click on the Inbox, I don't see the new message. With regard to the filesystem, the message is present and contains the intended contents. Here's the "stat" output: $ stat /var/vmail/example.com/ben/Maildir/cur/1471567777.M685753P32257.example.com,S=24:2, File: '/var/vmail/example.com/ben/Maildir/cur/1471567777.M685753P32257.example.com,S=24:2,' Size: 24 Blocks: 8 IO Block: 4096 regular file Device: fd01h/64769d Inode: 783925 Links: 2 Access: (0664/-rw-rw-r--) Uid: ( 5000/ vmail) Gid: ( 5000/ vmail) Access: 2016-08-18 20:51:05.647059340 -0400 Modify: 2016-08-18 20:50:58.543055378 -0400 Change: 2016-08-18 20:50:58.543055378 -0400 Birth: - Might anyone know why I'm not "seeing" this message in my IMAP client?

Reporting on CephFS being ready to use with Dovecot
by Daniel van Ham Colchete 18 Aug '16

18 Aug '16

I would like to report that from version 10.2.3 on (next release), Ceph FS is working really well with Dovecot systems. For those that don't know, Ceph is a "distributed object store and file system designed to provide excellent performance, reliability and scalability.". We have used it here since 2013 very successfully, but never with our Dovecot setup. For more information go on http://ceph.com/. Since Ceph Jewel (the current version), Ceph FS is considered production ready by their team. With Ceph FS you have a cache-coherent POSIX-compliant [1] clustered file system, without most of the NFS shortcomings. Ceph have very nice features like online upgrades, online maintenance, constant deep scrubbing of replicated data, cache tiering (HD -> SSD -> etc), erasure coding (clustered RAID6 for really old email - I'm not using), etc. Ceph is very complex to operate but very flexible and robust. This year we moved our Dovecot servers to a Ceph based system, found one bug there (http://tracker.ceph.com/issues/15920) when Dovecot's LMTP was delivery an email, and the fix is about to be released on version 10.2.3. I have been using a fix-build here for a couple of months without issue. So, now I'm glad to share with you guys that it works really well! My setup involves two clusters, each with about 30k-40k users. Each cluster will have two HD storages (with 6TB HDs), two SSD storages (with Intel 480GB SSDs) and two frontends. In a few months will add a third server of each type. Clusters work better with 3's. Here we used mdbox as it is better performant on Ceph for maintenance tasks, since each file is an object on Ceph and maintenance costs increase with the number of objects. We created two base directories: - /srv/dovecot/mail/%d/%n - stored on HDs with the most recent files cached on SSDs, thanks to Ceph Cache Tiering. Also, the directory structure itself is stored on SSDs, so dir listings are very fast (Ceph FS Metadata). - /srv/dovecot/index/%d/%n - stored only on SSDs, thanks for Ceph FS file layout. On our setup about 17% of the IOPs are going to HDs, the rest will go to SSDs, even though SSDs are less than 5% of the space. This is a matter of tuning the cache tiering parameters, but we didn't look at that yet. That setup is working like a charm, performance is about 53% better than when we were using NFS on the same hardware. Our previous DRBD+Heartbeat setup didn't allow for online maintenance and had a few problems. Now we can do 100% online maintenance on storage without users noticing, and on frontends with just a reconnect but without any downtime. Ceph is hard to learn at first but those with bigger setups and stronger SLAs will want to take a look at that. I really recommend that the Dovecot community take at look at that setup. Good luck! Best, Daniel Colchete [1] http://docs.ceph.com/docs/hammer/dev/differences-from-posix/

POP3 strange logging behavior after upgrade from 2.2.13 to 2.2.25
by Iavor Stoev 18 Aug '16

18 Aug '16

Hello, After the upgrade from Dovecot version 2.2.13 to 2.2.25, we experience the following strange behavior with POP3 logging. When a connection is closed with reason "Connection closed" & "Disconnected for inactivity", the number of deleted mails is missing. Like del=/1166 & del=/4138 from the example bellow. With Dovecot 2.2.13: Feb 14 03:35:20 serverXYZ dovecot: pop3(user(a)domain.com): Connection closed top=0/0, retr=0/0, del=0/946, size=39500197 Feb 15 16:49:18 serverXYZ dovecot: pop3(user(a)domain.com): Disconnected for inactivity top=0/0, retr=0/0, del=0/739, size=52319632 With Dovecot 2.2.25: Jul 31 02:56:03 serverXYZ dovecot: pop3(user(a)domain.com): Connection closed top=1/1380, retr=0/0, del=/4138, size=284167741 Jul 31 02:34:47 serverXYZ dovecot: pop3(user(a)domain.com): Disconnected for inactivity top=0/0, retr=0/0, del=/1166, size=111425436 For sessions completed normally, everything works fine with both Dovecot versions: Jul 31 06:55:48 serverXYZ dovecot: pop3(user(a)domain.com): Disconnected: Logged out top=0/0, retr=0/0, del=0/0, size=0 Jul 31 02:36:59 serverXYZ dovecot: pop3(user(a)domain.com): Disconnected: Logged out top=0/0, retr=1/18821, del=1/1, size=18803 Please advise if this behavior is normal and if yes how should we read entries like "del=/4138"?

dsync replication issue
by Cédric ML 18 Aug '16

18 Aug '16

Hello, I'm facing a problem with dsync : replication between my two dovecot 2.2.10 servers (10.10.10.10 = serverA and 10.10.10.11 = serverB) is not done when a mail is received on any of the two servers. Sync is correctly working when running "doveadm [-D] sync -A tcp:10.10.10.10:12345" from serverB or "doveadm [-D] sync -A tcp:10.10.10.11:12345" from serverA Sieve vacation message replication is functional too, and triggered when a change is done on any of the two servers. I guess it's a notify problem, but I did not find how to debug it... I've enabled dovecot debug, but I don't see anything related to notify in logfile. Here's my doveconf -n (it's the same on the two servers, except IP address changes) Hope somebody will be able to help me.

dsync: Keywords not being replicated

I just noticed that some IMAP keywords are not being replicated through dsync backup/sync using Dovecot 2.2.24 from Debian backports: On the master server everything looks fine: RECORD: seq=3, uid=44731, flags=0x09 (Seen Answered) - ext 0 keywords : (0900) <-- 0900 - ext 1 modseq : 701695 (ffb40a0000000000) - ext 3 cache : 3948 (6c0f0000) - ext 4 sort-s : 0 (00000000) On Replica: RECORD: seq=3, uid=44731, flags=0x09 (Seen Answered) - ext 0 keywords : (0000) <-- 0000 - ext 1 modseq : 701695 (ffb40a0000000000) - ext 3 cache : 3948 (6c0f0000) In this case the "forwarded" keyword is gone. Thunderbird no longer displays the message as having been forwarded. The command I used was: > doveadm sync -u myuser -l 60 -N tcp:replica:24245 My config is attached.

[Dovecot] How to disable SSL and TLSv1.1?
by Darren Pilgrim 16 Aug '16

16 Aug '16

I'm running Dovecot 2.2.5 and want to make it refuse SSLv2, SSLv3 and TLSv1.0. Clients will opportunistically use TLS 1.1 and 1.2, but now I want require they do so. Is it enough to set ssl_cipher_list = HIGH:!SSLv2:!SSLv3:!TLSv1.0:!aNULL:!MD5 or are there additional settings I need to specify?

public namespace quota
by Chris 16 Aug '16

16 Aug '16

All, sorry, I've to ask again. I'm trying to define quotas for public namespace subfolders: ns=public/ - DepartmentA - 50G - DepartmentB - 500M - DepartmentC - 10G public/ shouldn't have a limit. public/DepartmentA is independent of B and C. Is this possible with dovecot? I've added the following rules quota = maildir:User quota quota2 = maildir:Public quota:ns=public/ quota2_rule = *:storage=10M quota2_rule2 = DepartmentA:storage=+50M but then only 10M is shown for DepartmentA in Thunderbird. I'm using Maildir++. maildirsize is only created in public/ toplevel, not in public/DepartmentA. Public-subfolders are owned by vmail system-user. Different virtual users' ACLs are set (and working). Any help is appreciated! - Chris

Symbolic link for sieve script not created by dsync
by Laz C. Peterson 15 Aug '16

15 Aug '16

Hello Dovecot ~ I know this bug has been discussed previously for other versions of dsync, pigeonhole and dovecot … But we still can’t get dsync to create the symbolic link for the sieve script after it is created on a replicated server. We are running Ubuntu 16.04.1 with the official Ubuntu dovecot packages (2.2.22). Sieve script itself is replicated, but not the symbolic link. Any suggestions? ~ Laz Peterson Paravis, LLC

fts-solr autoindex issue in public mailbox
by maks 15 Aug '16

15 Aug '16

Hello everyone, I have a public mailbox: /var/mail/example.com/public/public_mailbox with "Public/" namespace set up in config file. When i move message from user's INBOX to one of mailboxes inside Public/ (for example Public/archive), i'm getting "indexer-worker: Info: Indexed 0 messages in Public/archive" in logs and i can't find the message through the FTS search. If i move the message back from Public/archive into personal mailbox the message is indexed by indexer-worker "indexer-worker: Info: Indexed 1 messages in temp_folder" If i perform "doveadm index Public/archive" then the message is added to the index. Dovecot version: 2.2.9 FTS backend: Solr fts_autoindex = yes Searching through localhost:8983/solr/collection1 gives the same result.

Bug with shared access to mailbox
by van der Kamp, John 15 Aug '16

15 Aug '16

Hello, I'm testing dovecot with some setups, and one of them is with shared mailboxes. The test I wrote will create and delete mail using multiple connections to the same user and folder. Each connection makes a couple of mails, remembers the uid from APPENDUID, and will delete those emails again. At the end of the test I expect an empty folder. This is not what happens. At the end I still have several mails in the folder. I lack insight in the dovecot source to tell exactly what's going on. I've tested this with different setups: 1) local system user, connecting over localhost -> bug is present 2) local system user, connecting over internet -> bug is present, but is harder to reproduce 3) dovecot as proxy to another imap server -> bug is present In step 3, you can even setup a dovecot to be a proxy to another dovecot server. >From logging in the other imap server I've seen that a client command to the proxy like: TAG UID STORE 1:3 +FLAGS (\Deleted) TAG UID EXPUNGE 1:3 will be sent to the other imap server in 3 steps, one for each message. When running the test with multiple threads, that logging shows that some uids are never sent to the other imap server, and some uids are sent over different connections than they original were sent to. (Thread 1 deletes 1:3, Thread 2 deletes 4:6, the proxy of Thread 1 might expunge messages from Thread 2 and vice versa). Attached is a python script which tests the behavior. The script expects a file named "testmail.eml" to upload to the imap server. I used an email which was about 75 kB. I tested using version: 2.2.22 (fe789d2). Let me know if I can help in any other way too. John

Save user passwords in clear text

Is it possible to save user passwords as clear text through dovecot? I am currently using MD5 passwords and I allow only "plain and login” mechanisms but I want to switch my database to clear text as this will give me the ability to use more mechanisms such as CRAM-MD5. Is this possible? Thank you

receiving and associating emails to single a/c
by David Tildesley 13 Aug '16

13 Aug '16

Hi,Looking for advice.Scenario: we have a dmz mta that currently redirects received emails for a selection of email domains to specific internal ms exchange servers. We want this mta to redirect incoming customer emails directed to a set of email addresses numbering about 30, to a dovecot server and associate these emails to a single dovecot user account so that a contact Centre platform can pull these emails on a frequent cycle.How to go about configuring this on the dovecot? I assume a postfix server needs to be installed on the dovecot server for the dmz mta to send these emails to dovecot inbox? Any advice most appreciated. David. Sent from Yahoo Mail on Android

Dovecot Director self ip
by Tomaž 12 Aug '16

12 Aug '16

Hello everybody! I kindly ask somebody to help me with this problem. I'm trying to configure Dovecot proxy with Director. On the same machine is KeepAlived that needs this configured to bind non local IP: sysctl net.ipv4.ip_nonlocal_bind=1 But as already mentioned in this email: http://www.dovecot.org/list/dovecot/2012-November/087033.html Dovecot Director needs sysctl net.ipv4.ip_nonlocal_bind=0 (if this is set, everything works ok, but we break keepalived) because otherwise the second server uses IP from the first server as "self". Is it possible to configure this some other way, so Dovecot Director doesn't try to bind to all IPs and because of above configuration, uses the first one that binds. This is the result from director status on server 1: root@u1:~# doveadm director ring status director ip port type last failed status 172.16.100.191 9090 self never handshaking 172.16.100.192 9090 never handshaking and server 2: root@u2:/var/log# doveadm director ring status director ip port type last failed status 172.16.100.191 9090 self never handshaking 172.16.100.192 9090 never My dovecot config: http://pastebin.com/RnmHRWhY Thank you very much!

dovecot 2.2.25 & deleting emails from \Junk special-use assigned folder

Since our cPanel installation upgraded Dovecot from 2.2.23 to 2.2.25, deleting emails located in the Junk folder (\Junk special-use), the emails end-up in the \Trash special-use folder instead of being purged as before. Is there something that changed or this some configuration I am missing? Thanks for any help regarding this. -- Marc Jauvin Register4less, Inc. 514-905-6500 x403

Replication issue EOF or unknown flag V

Hi, I'm trying to sort out a replication error: It was working initially, but now it no longer works. Dovecot 2.2.25, Maildir format Delivering via LMTP.

custom mail_location detection for dovecot lda
by Alexander 'Leo' Bergolth 09 Aug '16

09 Aug '16

Hi! Is it possible to do something like "post-login scripting" to detect and set a per-user custom mail location for dovecot LDA delivery? I tried to use a wrapper-script around dovecot-lda that sets the environment variables MAIL="..." and USERDB_KEYS="MAIL" just like overriding userdb fields may be done using imap postlogin scripts, but unfortunately this doesn't seem to be honored. (Also tried with dovecot-lda -k.) Woud be very useful for slow migration from one mailbox format to another. Is there any other way to supply a custom mail_location to dovecot-lda?

Questions about how fts-solr works
by Radu Gheorghe 08 Aug '16

08 Aug '16

Hello, I'm quite a Dovecot newbie, so please be gentle :) Though I did my homework as well as I could, I still have some questions regarding the Solr plugin. Specifically: - I understand that by default, a mailbox is indexed on the first search and then deltas are indexed in subsequent searches. Are Emails indexed in batches or one by one? Looking at the code, I see a hardcoded limit of 1000, and I'm guessing if the mailbox is done and there are <1000 Emails in the buffer, it just flushes them, right? - if I set fts_autoindex=yes, does it mean that as soon as the Email is delivered by the MTA, it will be indexed in Solr? or does it have to read by the user or touched in any way? - also, with fts_autoindex=yes, are Emails indexed in batches? if yes, is there also a time limit besides the size limit? e.g. if only 100 messages were received - I have the same question about deletes: when do they happen, and are they batched? - what happens if Solr is unavailable? I know Dovecot keeps track of what indexed in dovecot.indexed files, but does it retry? if yes, what's the retry policy and can it be configured? Also, does it behave the same if Solr is actually available and throws an error? - the same question is for attachments, though I think this is general FTS - what if Tika fails to parse the attachment? Does Dovecot still index the Email metadata? As a side, I'm also wondering if I could use the Tika that comes with Solr (https://cwiki.apache.org/confluence/display/solr/Uploading+Data+with+Solr+C…) Can fts-solr handle attachments at all? I'm asking because I don't see that field in the default schema.xml - can I add arbitrary URI parameters to the Solr request? I see that one could fiddle with the path, which I assume will let one have one collection per mailbox (though I'm curious how that works with batches - I'm guessing one batch/indexing thread per mailbox?). Specifically, I'm interested in using the mailbox as a routing value - if I read the code well, Dovecot does a soft commit when it's done with the specific mailbox. For indexing at search time, I see why it makes sense. If I do "autoindex", can I disable that and let Solr autoSoftCommit every N seconds? That should improve indexing throughput and reduce load. I see that one can already do this for hard commits (I'd use autoCommit there, though a hard commit is also triggered when ramBufferSizeMB gets hit) - when querying, can I sort by an arbitrary field, such as the date? I saw I can sort by score, but I can't find anything in the code that will suggest it's supported - also when querying, can I specify which fields to return? I see that the plugin asks for Email ID, so I'm guessing it fetches things like from/to from the Email itself. I'm thinking that if I want to sort by those values I need to set docValues=true on them, to save memory. In that case, I might as well retrieve the original string from docValues, which should be a whole lot faster My plan is to do all sorts of tests, but having a better background on how it works will certainly help. Any pointers, feedback, encouragement, etc is certainly welcome - thanks in advance!

Dovecot password policy
by Robert Blayzor 06 Aug '16

Is there a way to configure Dovecot to perhaps filter/enforce which passwords are accepted before authenticating? Ie: Reject immediately (without a database lookup) if password is not X characters in length? ? -- Robert inoc.net!rblayzor XMPP: rblayzor.AT.inoc.net PGP Key: 78BEDCE1 @ pgp.mit.edu

Yes, use the checkpassword hook. http://wiki.dovecot.org/AuthDatabase/CheckPassword I think there also some PAM module that you can stack into your system that will enforce password policies.

Dovecot and Solr 6
by KSB 05 Aug '16

05 Aug '16

Hi! Dovecot 2.2.24 Had set up solr and new schema collection. Copied dovecot provided schema. There was an error with booleans (while getting schema via http), which I "solved" by removing "add-unknown-fields-to-the-schema" from solrconfig.xml. It is correct way to solve this? Anyway, I run tcpdump to see network activity between dovecot and solr: #tcpdump -i lo port 8983 and see nothing while doing: #doveadm fts rescan -u username(a)domain.tld no output also from doveadm. Noticed that dovecot.index.log reapears in user mail root if deleted. plugin { fts = solr fts_solr = url=http://localhost:8983/solr/dovecot/ debug .. } -- KSB

Problem with sieve configuration on dovecot+debian_jessie+ISPC3
by Filip Loncar [WarpMax | FederationServers] 05 Aug '16

05 Aug '16

I'm new-ish to dovecot and sieve (haven't used it extensively till now) and I'm not sure that I configured everything propperly. The problem is that we're trying to get the following sieve code to run: require ["fileinto", "regex", "date", "relational", "vacation", "duplicate"]; require "duplicate"; if duplicate :header "message-id" { discard; } else { redirect "<somemail1>"; redirect "<somemail2>"; redirect "<somemail3>"; redirect "<somemail4>"; redirect "<somemail5>"; redirect "<somemail6>"; keep; } keep; But we're constantly getting the following error: sieve: info: started log at Aug 02 08:13:21. main script: line 5: error: require command: unknown Sieve capability `duplicate'. main script: line 6: error: unknown test 'duplicate' (only reported once at first occurence). main script: error: validation failed. Both me and my collegue can't find what's wrong with the system. I would appreciate any kind of help on this matter.
