dovecot as proxy and verification of the backends certificate
by Heiko Schlittermann 13 Oct '15

13 Oct '15

Hello, I'm using a dovecot as proxy, connecting to one or more backends. The backends use X.509 certificates. The proxy's passdb returns extra fields: user=foo proxy host=backend1.<domain> ssl=yes nopassword=y Thus the proxy connects to the backend but can't verify the backends certificate. The following comment suggests using ssl_client_ca_file for that. # Directory and/or file for trusted SSL CA certificates. These are used only # when Dovecot needs to act as an SSL client (e.g. imapc backend). The # directory is usually /etc/ssl/certs in Debian-based systems and the file is # /etc/pki/tls/cert.pem in RedHat-based systems. #ssl_client_ca_dir = #ssl_client_ca_file = ssl_client_ca_file = /tmp/certs/ca-local.pem But that does not work! Instead I've to use ssl_ca # PEM encoded trusted certificate authority. Set this only if you intend to use # ssl_verify_client_cert=yes. The file should contain the CA certificate(s) # followed by the matching CRL(s). (e.g. ssl_ca = </etc/ssl/certs/ca.pem) # ssl_ca = ssl_ca = </tmp/certs/ca-local.pem Bug or feature? Mainly I'm asking because the comments do not indicate that I should have used ssl_ca for this type of operation (dovecot as a SSL client) Best regards from Dresden/Germany Viele Grüße aus Dresden Heiko Schlittermann -- SCHLITTERMANN.de ---------------------------- internet & unix support - Heiko Schlittermann, Dipl.-Ing.

Dovecot auth-ldap ignores tls_* settings when using ldaps://
by Heiko Schlittermann 13 Oct '15

13 Oct '15

Hi, I'm using dovecot 2.2.9 (but after checking src/auth/db-ldap.c in 2.2.13 there seems to be the same bug/feature). The userdb and passdb use LDAP. All further configuration is done in auth-ldap.conf.ext. uri = ldaps://<host>/ # tls = tls_cert_file = /etc/ssl/certs/client-cert.pem tls_key_file = /etc/ssl/certs/client-key.file Dovecot ignores the tls_* options. If I use an ldap:// URI and switch on TLS using tls=yes it works as expected. But I do not see any reason why LDAPS should not read the tls_* settings. This small patch solved it for me --- dovecot-2.2.9/src/auth/db-ldap.c 2013-11-24 14:37:39.000000000 +0100 +++ dovecot-2.2.9.hs12/src/auth/db-ldap.c 2015-10-08 21:24:47.051446465 +0200 @@ -1043,7 +1043,7 @@ static void db_ldap_set_tls_options(struct ldap_connection *conn) { - if (!conn->set.tls) + if (!(conn->set.tls || strncmp(conn->set.uris, "ldaps:", 6) == 0)) return; #ifdef OPENLDAP_TLS_OPTIONS It would be great, if somebody can confirm this and if this or some equivalent patch could make it upstream.

Multiple core solr support
by Daniel Miller 13 Oct '15

13 Oct '15

Is it possible to use variables, such as domain or username, in the plugin url declaration? This would allow using multiple cores to separate the stored indexes. So when my own giant mailbox gets corrupt...I don't have to rebuild everybody's... Something like url=http://mysolr.server.com:8983/solr/%u -- Daniel

fts solr ignores new mailboxes until fts rescan
by Giorgio Paolucci 13 Oct '15

13 Oct '15

Hello, on my debian wheezy installation, I implemented fts plugin with solr as indexing system. I noticed that if a user creates a new folder, that folder it is ignored by dovecot indexing until a doveadm fts rescan is performed for that user. From that time on everything works ok on that folder. As a test I set fts_autoindex=yes and put in that folder a brand new mail never indexed before. in my logs indexer-worker says it indexed 0 messages Obviously this is a major issue as users often create new folders, but a search always returns empty results. My system is a debian wheezy with dovecot packages from backports dovecot 2.2.13-11~bpo70+1. Am I missing something? Any clue would be appreciated. Thank you all in advance.

Does anyone have this issues? I think that can be a problem in the configuration Best regards

iterate users with passwd-file passdb?
by Eric Abrahamsen 12 Oct '15

12 Oct '15

Apologies for the basic question, but I've been googling and can't figure out if this is possible or not. Simply: Is it possible to iterate over users if I'm using the passwd-file passdb driver? Do I need a SQL-based driver if I want to iterate? Here's what I've got right now. I don't have many users, and would prefer to retain the simplicity of the passwd-file if possible. Thanks! passdb { driver = passwd-file args = username_format=%u scheme=ssha512 /etc/dovecot/passwd.db deny = no master = no pass = no skip = never result_failure = continue result_internalfail = continue result_success = return-ok } userdb { driver = static args = uid=5000 gid=5000 home=/var/mail/vmail/%d/%n }

Syncronizing two IMAP servers
by Timothy Murphy 10 Oct '15

10 Oct '15

I spend time in two places, in different countries. I have a local network in each place, with IMAP servers on each network. I collect email by fetchmail from various servers, and read email on my laptop with KMail. I tried using just one IMAP server, but this proved impractical. So I have two collections of the same sub-folders, on the two servers. I have two questions: 1. Is there a simpler way of organizing my email? 2. Given the current method, is there a way of syncronizing folders on the two servers? -- Timothy Murphy gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin

Maildir: ACLs/Unix perms and unable to see content of specific mailbox
by Olaf Marzocchi 10 Oct '15

10 Oct '15

Dear Dovecot users, hello. I will merge two issues I have into a single email because they may be related. I used dovecot on a OmniOS server since 2014 (currently OmniOS r151014) with the following configuration (it shows 2.2.18 because I recently updated dovecot, skipping only the PostgreSQL plugin): # 2.2.18: /etc/dovecot/dovecot.conf # OS: SunOS 5.11 i86pc zfs mail_location = maildir:/tank/home/%u/Maildir mail_privileged_group = mail namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { driver = pam } protocols = imap ssl = required ssl_cert = </etc/dovecot/certs/dovecot.pem ssl_key = </etc/dovecot/private/dovecot.pem userdb { driver = passwd } You can see that I set the Maildir folder inside the shared home folders of my server (it is only one user, anyway). It always worked perfectly, but one-two months ago I changed the permissions of my whole home folder, recursively, to add proper ACLs. I needed them because the clients started using illumos kernel SMB (relying on ACLs) instead of Netatalk/AFP (relying on Unix perms only). I didn't realise I applied the ACLs also to the Maildir folder. Dovecot worked for several weeks fine, I noticed the issue only yesterday when a mailbox (see below) appeared in Thunderbird completely empty even if the "cur" subfolder on the server still contains all the mails. Dovecot was throwing some errors like: dovecot: [ID 583609 mail.error] imap(olaf): Error: rename(/tank/home/olaf/Maildir/.&A6k- Mailing Lists.Log/dovecot.index.cache) failed: Permission denied (euid=501(olaf) egid=501(olaf) UNIX perms appear ok (ACL/MAC wrong?)) dovecot: [ID 583609 mail.error] imap(olaf): Error: rename(/tank/home/olaf/Maildir/.&A6k- Mailing Lists.Log/dovecot.index.tmp, /tank/home/olaf/Maildir/.&A6k- Mailing Lists.Log/dovecot.index) failed: Permission denied dovecot: [ID 583609 mail.error] imap(olaf): Error: unlink(/tank/home/olaf/Maildir/subscriptions.lock) failed: Permission denied dovecot: [ID 583609 mail.error] imap(olaf): Error: rename(/tank/home/olaf/Maildir/subscriptions.lock, /tank/home/olaf/Maildir/subscriptions) failed: Permission denied I will post here the current permissions of the folder containing Maildir, of the Maildir itself, of its contents, and of the folder that appears empty when browsed with a client (Thunderbird). /tank/home/olaf $ ls -lV .. drwx------+ 16 olaf olaf 17 Sep 19 01:52 olaf user:olaf:rwxpdDaARWcCos:fd-----:allow group:2147483648:rwxpdDaARWcCos:fd-----:allow everyone@:rwxpdDaARWcCos:fd-----:deny /tank/home/olaf $ ls -lV drwxrwx--- 348 olaf olaf 359 Sep 19 01:51 Maildir owner@:rwxp--aARWcCos:-------:allow group@:rwxp--a-R-c--s:-------:allow everyone@:------a-R-c--s:-------:allow /tank/home/olaf $ ls -lV Maildir/ drwxrwx--- 2 olaf olaf 2 Jan 30 2014 cur owner@:rwxp--aARWcCos:-------:allow group@:rwxp--a-R-c--s:-------:allow everyone@:------a-R-c--s:-------:allow -rwxrwx--- 1 olaf olaf 21 Jan 30 2014 dovecot-keywords owner@:rwxp--aARWcCos:-------:allow group@:rwxp--a-R-c--s:-------:allow everyone@:------a-R-c--s:-------:allow (ALL THE SAME PERMISSIONS FOR THE OTHER FILES EXCEPT...) -rwxrwx--- 1 olaf olaf 13735 Jan 24 2015 subscriptions owner@:rwxp--aARWcCos:-------:allow group@:rwxp--a-R-c--s:-------:allow everyone@:------a-R-c--s:-------:allow -rw-rw---- 1 olaf olaf 13709 Sep 19 01:51 subscriptions.lock owner@:rw-p--aARWcCos:-------:allow group@:rw-p--a-R-c--s:-------:allow everyone@:------a-R-c--s:-------:allow The folder that appears empty: /tank/home/olaf $ ls -lV Maildir/.Generiche/ total 513 drwxrwx--- 2 olaf olaf 949 Sep 18 01:42 cur owner@:rwxp--aARWcCos:-------:allow group@:rwxp--a-R-c--s:-------:allow everyone@:------a-R-c--s:-------:allow -rwxrwx--- 1 olaf olaf 46 May 18 2014 dovecot-keywords owner@:rwxp--aARWcCos:-------:allow group@:rwxp--a-R-c--s:-------:allow everyone@:------a-R-c--s:-------:allow (ALL THE SAME PERMISSIONS FOR THE OTHER FILES) I really hope you will have the time to help me because I already applied the permissions recursively and I removed the ACLs, almost as it was before my mistake.

My questions, in short: - what are the permissions I need to give to the Maildir folder? I understood from the documentation it's 700, with my user/group (the one of the user accessing the mail). What about ACLs? and what about group "mail"? - the (only!) subfolder which appears empty in Thunderbird, may it depend on the permissions? maybe due to them the index was not updated and UIDs don't match. If after applying the correct permissions I still cannot see its contents, is there a way to recover the mails? the files are all still there. Sorry for the long email, but after several tries yesterday I exhausted my ideas. Regards, Olaf

I've noticed lately that Dovecot seems to be inserting an extra dot in some url's contained in html email. The most consistent example I see is in the newsletters from the Washington Post. For example, if I look at the raw email on the mail server I see text that starts <http://link.washingtonpost.com/click But if I look at what Thunderbird shows it starts http://link..washingtonpost.com/click/ I don't think its Thunderbird adding the dot, since K9 mail on my Android phone shows the same issue. It's only after the IMAP delivery that the extra dot appears. We are running dovecot 2.0.12 Incidentally, the newsletter is full of these link.washington post url's. For each article it appears 3 times, once on title, once on a "read full article" link, and one on a picture. Its only the one on title, that gets the extra dot after its been through dovecot. Furthermore, it only happens from the second article on. Any ideas?

Dovecot plugin and Push Mail
by Steffan Cline 08 Oct '15

08 Oct '15

I’m posting this here and will in a couple other places to see if anyone has any experience with this and knows what I can do. My setup is CentOS 6 with postfix, procmail and dovecot administered via Virtualmin. Postfix of course receives the email. Procmail uses it’s hooks to run the email through spam assassin and clamd. After than procmail hands it off to dovecot/deliver to drop it in the user’s mail box. I use the following plugin for dovecot with the daemon to provide Apple push mail for iPhones. https://github.com/st3fan/dovecot-xaps-daemon https://github.com/st3fan/dovecot-xaps-plugin For the most part, this works awesome but have run into a bit of a race issue with notification of mail in a particular instance. On my computer I use Outlook for Mac which says it supports IDLE but is broken. When an email comes in, I ALWAYS get the notification via the dovecpt plugin for a push since Outlook is checking IMAP every 2 minutes. On a buddy’s setup, he uses Apple Mail which supports IDLE that actually works. When his email client is connected from his laptop, it does actually maintain a persistent connection and NEVER receives a notification from the dovecot plugin because I’m guessing dovecot/deliver sees that the email was received by the desktop client. I’m not sure how to make the plugin ALWAYS give a push. Is it a dovecot config? A bug in the plugin? I’m not sure. Suggestions? Thank you, Steffan Cline 602-793-0014

how to treat synonymous domain names as one
by Nikolai Krot 08 Oct '15

08 Oct '15

Hallo List Users, I am curious if there is a way to rewrite domain name to another domain name. My goal is to provide authentication and mailboxes for the synonymous domains in a single source while keeping all other domains separate. I have setup: auth_username_format = %Lu mail_location = /var/vmail/%d/%u/Maildir in userdb/passdb (passwd-file): /etc/dovecot/%d/users Say I have two synonymous domain names my-domain-1.com my-long-named-domain-1.com I want both to resolve to my-domain-1.com when %d variable is used in Dovecot configs, so that passwd-file is /etc/dovecot/my-domain-1.com/users mailbox is /var/vmail/my-domain-1.com/user/Maildir while keeping other domains unchanged my-other-domain-2.com should resolve to: passwd-file is /etc/dovecot/my-other-domain-2.com/users mailbox is /var/vmail/my-other-domain-2.com/user/Maildir thanks, Nikolai

Dovecot don't erase mails from storage.

Hi, I have a dovecot installation with a strange problem: all the mails stays in storage after deleted from users mailbox.

Compiling v2.2.19 - internal compiler error: segmentation fault (test-timing.c -> int64_t issue?)
by Guest-X 05 Oct '15

05 Oct '15

Hi, I am trying to compile a 64-build of the latest dovecot v2.2.19 on my SuSE Linux Enterprise Server 10 (x64) system. I've run ./configure with two parameters, the --prefix one and the --with-ssldir one.

Can somebody help me please ? Thank you for your time.

Released Pigeonhole v0.4.9 for Dovecot v2.2.19
by Stephan Bosch 05 Oct '15

05 Oct '15

Hello Dovecot users, Here is the definitive 0.4.9 release. Only a few minor fixes were done since RC1. Changelog v0.4.9: * Properly implemented checking of ABI version for Sieve interpreter plugins, much like Dovecot itself does for plugins. This will prevent plugin ABI mismatches. + Implemented a vnd.dovecot.environment extension. This builds upon the standard environment extension and adds a few more environment items, such as username and default mailbox. It also creates a variables namespace so that environment items can be accessed directly. I am still thinking about more environment items that can be added. + Sieve extprograms plugin: Made line endings of the input passed to the external programs configurable. This can be configured separately for each of the three extensions. + ManageSieve: Implemented proxy XCLIENT support. This allows the proxy to pass client information to the back-end. - ManageSieve: Fixed an assert failure occurring when a client disconnects during the GETSCRIPT command. - doveadm sieve plugin: Fixed incorrect initialization of mail user. This caused a few memory leaks. - sieve-filter command line tool: Fixed handling of failure-related implicit keep when there is an explicit default destination folder. This caused message duplication. - lib-sieve: Fixed bug in RFC5322 header folding. Words longer than the optimal line length caused empty lines in the output, which would break the resulting message header. This surfaced in References: headers with very long message IDs. The release is available as follows: http://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.9.tar… http://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.9.tar… Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information. Have fun testing this new release and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

v2.2.19 released
by Timo Sirainen 03 Oct '15

03 Oct '15

http://dovecot.org/releases/2.2/dovecot-2.2.19.tar.gz http://dovecot.org/releases/2.2/dovecot-2.2.19.tar.gz.sig * pop3_deleted_flag has been broken since v2.2.10. Using it would cause buffer overflows, which could be exploitable. However, this bug would have become visible quite soon after users had deleted some POP3 mails, because the pop3 processes would have started crashing all the time even in normal use. * "doveadm director flush" command has a changed meaning now: It safely moves users to their wanted backends, instead of simply forgetting the mapping entirely and leaving the existing connections untouched. Use -F parameter to get the original unsafe behavior. + Added imap-hibernate processes (see imap_hibernate_timeout setting). IDLEing IMAP connections can be hibernated, which saves memory. + Optimized tracking mailboxes' vsizes (= sum of all messages' sizes). If mailbox_list_index=yes, it's also stored in there. This makes it very efficient to look up vsizes for all mailboxes. + Added a quota "count" backend, which uses the mailbox vsizes to get the current quota usage. It requires using the new quota_vsizes=yes setting, which tracks the messages' "virtual sizes" rather than "physical sizes". Their distiction is minor and mostly irrelevant nowadays (if mail sizes should be counted with LF or CRLF newlines). + "doveadm director up/down" commands added. The monitoring script should be using these commands instead of changing the vhost count. This allows admin to manually disable a server by changing the vhost count to 0 without the monitoring script changing it back. + Added support for HAProxy protocol: http://wiki2.dovecot.org/HAProxy + Added push-notification plugin framework, which can be used to easily implement push notifications to various backends. Implemented "ox" backend for notifying Open-Xchange via HTTP/json. + imap_logout_format supports more variables now, e.g. number of deleted messages. + pop3: Added pop3_delete_type setting (related to pop3_deleted_flag). + plugin { fts_enforced=yes } setting now fails body searches unless it can be done via the full text search engine. + Added %{passdb:*} and %{userdb:*} variables to various places + auth: Added ":protected" suffix for passdb and userdb fields. If used, the field doesn't overwrite an existing field. + IMAP/POP3 proxy: If a backend server dies, avoid client reconnection spikes by slowly disconnecting clients over time. This is enabled by setting login_proxy_max_disconnect_delay=secs passdb extra field. + imap: Added new read-only METADATA entries: /private/specialuse, /shared/comment, /shared/admin + imap: If client disconnects in the middle of a command, log how long the command had been running. - mdbox: Rebuilding could have caused message's reference count to overflow the 16bit number in some situations, causing problems when trying to expunge the duplicates. - Various search fixes (fts, solr, tika, lib-charset, indexer) - Various virtual plugin fixes - Various fixes and optimizations to dsync, imapc and pop3-migration - imap: Various RFC compliancy and crash fixes to NOTIFY

Hello, Thanks for the clarifications plugin { quota = maildir:User quota quota_rule = *:storage=1G quota_grace = 10%% # 10% is the default quota_status_success = DUNNO quota_status_nouser = DUNNO quota_status_overquota = "552 5.2.2 Mailbox is full" } The above configurations is my default for all users. but my mail system is using mbox format and not maildir.... so what should i change in the above configuration to use mbox INSTEAD of maildir ??

imap_logout_format improvements / ideas
by Timo Sirainen 03 Oct '15

03 Oct '15

http://hg.dovecot.org/dovecot-2.2/rev/93bba97afb2a http://hg.dovecot.org/dovecot-2.2/rev/e0a17714f0c9 So all in all, you can now add to imap_logout_format: # %i - total number of bytes read from client # %o - total number of bytes sent to client # %{fetch_hdr_count} - Number of mails with mail header data sent to client # %{fetch_hdr_bytes} - Number of bytes with mail header data sent to client # %{fetch_body_count} - Number of mails with mail body data sent to client # %{fetch_body_bytes} - Number of bytes with mail body data sent to client # %{deleted} - Number of mails where client added \Deleted flag # %{expunged} - Number of mails that client expunged # %{trashed} - Number of mails that client copied/moved to the # special_use=\Trash mailbox. Any thoughts on what else would be useful? I was also thinking about separating (deletes and) expunges from Trash vs non-Trash, but I'm not sure how useful that would be (and what would it be called?) It's also a bit annoying that a copy+expunge to a Trash will return expunged=1 trashed=1, but a move to Trash (via IMAP MOVE) will return expunged=0 trashed=1. But trying to fix that would be too much trouble.

/usr/lib/dovecot/imap exits with an error if stderr closed
by Josh Triplett 01 Oct '15

01 Oct '15

At the end of a direct IMAP conversation with the imap binary, it writes an informative message like "imap(josh): Info: Connection closed in=0 out=365" to stderr. With stderr closed, the imap binary will exit with exit code 81 after it gets EBADF from that write. While it makes sense to fail on failure to write an error message, I don't think it makes sense to fail if writing an info message fails. I encountered this when using /usr/lib/dovecot/imap with mutt's "tunnel" option. Mutt seems to run the configured tunnel program with stderr closed, which triggers this error. - Josh Triplett

Dovecot 1.0.10 - Authenticate against LDAP with multiple sub-trees
by Daniel Heitepriem 01 Oct '15

01 Oct '15

Hi guys, I'm using Dovecot 1.0.10 with LDAP authentication. Below is my dovecot-ldap.conf { hosts = *IP of LDAP server* auth_bind = yes auth_bind_userdn = uid=%u,ou=people,dc=*something*,dc=com ldap_version = 3 base = %u,ou=people,dc=*something*,dc=com deref = never scope = subtree user_filter = (&(objectClass=person)(uid=%u)) } And the current structure: Base | |-- people | | *user entries* | Now I want to update to a LDAP server with the following structure: Base | |-- people | |-- staff | | *user entries* |-- other location | | *user entries* | How can I keep my "auth_bind_userdn" using this new structure? Hopefully somebody can help me :) Regards, Daniel

SiS and attachments filename
by Angel L. Mateo 01 Oct '15

01 Oct '15

Hi, I've been working with dovecot SiS for a long time without any problem. This is my configuration for SiS: mail_attachment_dir = /mail/users/attachments mail_attachment_fs = sis posix mail_attachment_hash = %{sha1} mail_attachment_min_size = 128 k With this configuration, I have, for example: # ls -l /mail/users/attachments/27/d1/27d1904ac9947945bf48ea545ec278940d840ed1* -rw------- 12 vmail vmail 142914 may 6 2013 /mail/users/attachments/27/d1/27d1904ac9947945bf48ea545ec278940d840ed1-090d88269ad28851f14b0000a9061514 ... And every file is a hard link to /mail/users/attachments/27/d1/hashes/27d1904ac9947945bf48ea545ec278940d840ed1 For the documentation I have found, "27d1904ac9947945bf48ea545ec278940d840ed1" is a hash of the attach content, but what does the other part of the filename (the "090d88269ad28851f14b0000a9061514" means) My question has come to my mind because I need an easy way to find the mailbox where this attach is referenced from. -- Angel L.

Maybe you need to set the INBOX parameter directly. http://wiki2.dovecot.org/MailLocation Joseph Tam <jtam.home(a)gmail.com>

userdb prefetch doesn't work with imapc (2.2.18)
by Nagy, Attila 30 Sep '15

30 Sep '15

Hi, I have the following config in dovecot 2.2.18: # doveconf -n userdb passdb userdb { driver = prefetch } passdb { args = host=127.0.0.1 port=1430 default_fields = userdb_imapc_user=%u userdb_imapc_password=%w driver = imap } I guess it should cause a single login to the backend IMAP server when issuing a LOGIN to dovecot. Yet, dovecot opens two TCP sessions. In the first, it issues a LOGIN and in the second it logs in again (LOGIN) and issues LIST "" "". At the end (after LOGIN succeeds to dovecot), only one of the two connections remain open to the backend server. Any ideas about this? Thanks,

v2.2.19 release candidate 2 released
by Timo Sirainen 30 Sep '15

30 Sep '15

http://dovecot.org/releases/2.2/rc/dovecot-2.2.19.rc2.tar.gz http://dovecot.org/releases/2.2/rc/dovecot-2.2.19.rc2.tar.gz.sig There were still a bit too many bugs in RC1, so here's RC2. Hopefully this will be stable enough to become v2.2.19 final. Please test now rather than wait for v2.2.19 final, since v2.2.20 is unlikely to arrive anytime soon (unless there are some major problems). Some fixes since RC1: - dict fixes, especially with pgsql - virtual plugin crashfixes - quota "count" backend fixes - lib-http fixes - some compiling fixes

dovecot quota service for postfix
by Michael Peter 29 Sep '15

29 Sep '15

Hello, I am trying to use dovecot quota service for postfix in order set quota for some users. i configure postfix policy service to ask dovecot if user quota is sufficient to accept the email or not. (dovecot in this case acts only as policy server to postfix as it only ACCEPT/REJECT email according to user quota, but it is not used to deliver email , because postfix will deliver the email to user mailbox) Incase user is underquota, then the email is returned back to postfix for processing and delivering email to user mbox, incase user has no sufficient quota then dovecot will inform postfix to reject email. Please confirm if what i mentioned above is correct and that i understand correctly how dove-cot policy works with postfix. Kindly check my configuration below and advise the missing parts to add... plugin { quota_rule = *:storage=1G quota_grace = 10%% # 10% is the default quota_status_success = DUNNO quota_status_nouser = DUNNO quota_status_overquota = "552 5.2.2 Mailbox is full" ... } The above configurations is for all users which is not override by quota rules in userdb's extra fields in my password file below. Is the above configuration missing some thing ? i am using mbox format for emails storage. do you i have to add (quota= SOMETHING) before (quote_rule = *:storage=1G) and what to do add to make dovecot support mbox quota? smtpd_recipient_restrictions = check_policy_service inet:SERVER-HIDDEN-FOR-SECRUITY.com:12340 service quota-status { executable = quota-status -p postfix inet_listener { port = 12340 } client_limit = 1 } now in order to configure dovecot specific quota for user named (user1) i use passwd-file as follow user1:{plain}pass3:1002:1002::/home/user1::userdb_mail=mbox:~/mymail:INBOX=/var/mail/user1 userdb_quota_rule=*:bytes=300M All other users except users1 should have 1GB storage according to this configuration. which user1 will only have 300MB Please advise what is my configuration is missing and if i need to add any thing to run without issues. Many thanks Michael Peter

BINARY capability not working correctly?
by Jouko Nikula 29 Sep '15

29 Sep '15

Hello, I have trouble with some attachments not working on Horde and Roundcube. I made a ticket to Roundcube webmail and they tracked down it to Dovecot not responding correctly to BINARY FETCH: http://trac.roundcube.net/ticket/1490532 What is causing Dovecot to answer NIL? Is there an issue in Dovecot? If I want to disable to BINARY capability in Dovecot I need to use imap_capabilities. I found out that I could add capabilities with syntax imap_capabilities= +FOO but it seems I can't use similar syntax (imap_capabilities= -FOO) to remove capabilities? If I list all capabilities like: imap_capabilities= IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE AUTH=PLAIN SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS THREAD=ORDEREDSUBJECT MULTIAPPEND URL-PARTIAL CATENATE UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS SPECIAL-USE MOVE QUOTA I understood that this will result in listing all capabilities already pre-login. Is this a problem? Thanks, Jouko Nikula

mirroring one domain.tld to domain.tld.au
by voytek＠sbt.net.au 29 Sep '15

29 Sep '15

I have Postfix/Dovecot/postfixadmin/MySQL with several virtual mailbox domains one of the domains is like aname.com.au, the user also now has aname.com, and, would like to 'mirror' most of the addresses to be user(a)aname.com, THOUGH, some are to remain as user2(a)aname.com.au so, both user(a)aname.com as well as user(a)aname.com.au should be one user the users retrive emails as user(a)aname.com.au longer term... some would want to use aname.com.au. some, aname.com what's the best/proper way to do so in Dovecot ? I think I can do Postfix with postfixadmin to "Mirror addresses of one of your domains to another." but what do I do at the Dovecot end...? thanks for any pointers, suggestions or advice

distuguish between different domains
by Andreas Meyer 29 Sep '15

29 Sep '15

Hello! I asked myself wether it is possible to distinguish between different doamins in dovecot so that a user only sees his mailbox when he is connecting with user1(a)aaa.de specifying the server with mail.aaa.de for example. So the server does not handout the mailbox for user1(a)bbb.de when the client connects to mail.aaa.de as user1(a)bbb.de I have this problem with roundcube. Dovecot is responisble for two domains. With roundcube I can login as user1(a)aaa.de altough the client is configured like so: $config['smtp_server'] = 'tls://mail.bbb.de'; and I am landing in the mailbox of user1(a)aaa.de Is there a way to striktly differentiate between doamins? Both domains have their own IP-addresses. Regards Andreas

Newbie why is dovecot classified diff then sendmail or courier
by David Niklas 29 Sep '15

29 Sep '15

Hello, this is probably a dumb question, but I can't for the life of me figure out why sendmail and courier are classified universally as network-mail-mta whereas dovecot is in places like network-mail-general or some such place. I've used several Linux distros and have noted this keenly (they also normally classify photorec, the HD recovery tool as hardware-photography,so this may just be a mistake). I'm concerned that I'm looking into the wrong software for an mail transport/delivery agent. Thanks, David

doveadm fetch line wrapping
by Peter Chiochetti 28 Sep '15

28 Sep '15

The manual at http://wiki2.dovecot.org/Tools/Doveadm/Deduplicate tells how to estimate what will be expunged: > doveadm -f table fetch -u jane 'guid uid' mailbox a_Box | sort I wanted to learn the subjects: > doveadm -f table fetch -u jane 'guid hdr.Subject' mailbox a_Box In the output, long lines will be broken up, continuation lines starting with a blank (mostly), disabling the sort > doveadm -f table fetch -u jane 'guid hdr.Subject' mailbox a_Box \ > | sed -e :a -e '$!N;s/\n\s//;ta' -e 'P;D' | sort --stable Some (gnu) sed foo joins them back together, the sort works again :) -- peter

Hi, I have been using dovecot for multiple years, without a problem so far. I'm running version 2.0.19-0ubuntu2.2. A few weeks ago, the following problem started. When sending an e-mail with Thunderbird, the message is saved to the "Sent" IMAP folder after sending it out. Every few days, this

Sieve and forward
by Il Neofita 28 Sep '15

28 Sep '15

Hi I have already posted to the postfix group, however, I believe that sieve and dovecot should be able to fix this problem. When I receive a message from yahoo and the user forward it to a gmail or yahoo acount this email is considered as spam or rejected. >From yahoo is rejected since it seems that I am try to send spam since the email should be signed with dkim. Is there a way to encpuslated or sign in some way. Thank you

dovecot, fts, solr5 patch, fuzzy search
by Sergey Urushkin 28 Sep '15

28 Sep '15

Hi! I have a patch and several thoughts about FTS in dovecot. I. SOLR v5.1 and above doesn't allow GET /select queries with Content-Type header set, so, I just removed it from the code: --- dovecot-2.2.18/src/plugins/fts-solr/solr-connection.c 2015-05-13 17:14:45.000000000 +0300 +++ dovecot-2.2.18.patch/src/plugins/fts-solr/solr-connection.c 2015-09-27 19:47:40.363843359 +0300 @@ -432,7 +432,6 @@ solr_connection_select_response, conn); http_client_request_set_port(http_req, conn->http_port); http_client_request_set_ssl(http_req, conn->http_ssl); - http_client_request_add_header(http_req, "Content-Type", "text/xml"); http_client_request_submit(http_req); conn->request_status = 0; After that it works just fine. And it seems it doesn't hurt compatibility with older versions. Tested with 3.1, 3.6.2, 4.10.4, 5.3.1 So, I think this patch should be included. II. Fuzzy search. As I understand dovecot searches the same way despite FUZZY word is given or not. In my case I'd like to have an ability to make lookups like "domain.com usernamepart" (usernamepart - part of localpart). So, I use '<str name="defType">edismax</str><int name="qs">15</int>' inside requestHandler /select in solrconfig.xml. It's very convenient for users. Besides other things, this makes searches "abc@def" and "def@abc" identical to dovecot. But the problem is that sometimes the exact match is necessary. E.g. when using "doveadm expunge". For now I found a workaround - remove fts plugins while using doveadm with -o "`dovecot -n | sed -n 's/"//; s/ *= */=/; /^mail_plugins/s/$"\| fts\(\|_[^ ]\+$\)//gp'`". But I think users should have an ability to decide which search type to use. Here is what I'm suggesting: 1. Implement fts_fuzzy_default option (default - true, current behavior). false should disable fuzzy search by default. 2. Make a way for fts backend to choose which search type to use. For solr it would be an ability to specify: a) "handler" (default=select) and "handler_fuzzy" (default=select or handler's value) (the same as handler by default). After this you have to create second select-like handler with fuzzy capabilities in solrconfig.xml. Example: fts_solr = url=http://127.0.0.1:8983/solr/dovecot/ handler=select handler_fuzzy=select2 This method will use the same index for both search types. b) "url_fuzzy" URL (different solr core or even address/port), like this: fts_solr = url=http://127.0.0.1:8983/solr/dovecot/ url_fuzzy=http://127.0.0.1:8983/solr/dovecot_fuzzy/ This method will allow to have two completely different indexes. And according to RFC 6203 search query generally may be mixed (FUZZY/EXACT). Both options will be useful in different setups. Hope, these thoughts will help. -- Best regards, Sergey Urushkin

v2.2.19 release candidate released
by Greg Wildman 28 Sep '15

28 Sep '15

Hello, I am trying out 2.2.19.rc1 on a lightly loaded server with no problems so far. The reason I wanted to try 2.2.19.rc1 was to get access to the %{listener} variable in the auth phase so I can modify the SQL password_query according to which unix_listener is being queried. According to the docs, "These variables work only in Dovecot-auth and login_log_format_elements setting". I can confirm that %{listener} works in login_log_format_elements but it does not work if I use it in my SQL auth query. My logic is as follows: I create multiple listeners for different SASL authentications in 10 -master.conf service auth { unix_listener auth-userdb { mode = 0660 user = dovecot group = vmail } unix_listener exim-client { mode = 0660 user = dovecot group = exim } unix_listener xmpp-client { mode = 0660 user = dovecot group = mail } user = $default_internal_user } Now I want to use %{listener} in my SQL password_query in a case statement to auth according to which listener is being used. E.g. CASE '%{listener} ' \ WHEN 'exim-client' THEN ma.SMTPAUTH_allowed = 'YES' \ WHEN 'xmpp-client' THEN ma.XMPP_allowed = 'YES' \ ELSE ma.IMAP_allowed = 'YES' \ END Should the %{listener} variable work in this case ? -- Greg

modify message with doveadm?
by Frank-Ulrich Sommer 27 Sep '15

27 Sep '15

Hello, I'm using dovecot with getmail and spamassassin. To re-learn false detected mails I created two folders and use an external script that checks the corresponding maildir directories for changes (with inotifywait). The mails found in these directories are passed to sa-learn (to re-learn the correct classification) and then moved back to the inbox or the spam folder. To access the mail I use "doveadm search" (to find all mails in the two folders), "doveadm fetch" (to get the text and pass it to sa-learn) and "doveadm move" (to move the mail to the correct location. This works as desired, except that a mail once marked as spam will forever be marked as such. Spamassassin has the -d option to remove the markup, but I need to replace the original mail with the cleaned version. The only idea I got was deleting that mail and importing the cleaned one, but as I want to implement several "special" folders for further functionality with different IMAP clients I would prefer a "cleaner" solution. What would be the correct/best way to modify the mail body/header/text from an external tool? Kind regards, Frank

Hi All! I'm also hitted by this problem. I'm trying to migrate emails from very old dbmail to dovecot (maildir). I read old threads with similar problem but I found only such solutions: - upgrade to 2.2.13 - workarround : use imapsync - no solution I'd like to not use imapsync, have you got an idea what should I

Sieve - multiple cores/CPUs
by Paweł Grzesik 25 Sep '15

25 Sep '15

Hi All, I have a quick question about the Sieve in Dovecot. I know that this is a plugin so probably it depends on the Dovecot itself but: is it able to use multiple cores/CPUs when doing the filtering? does the filtering for each mail user run on a separate core? Thanks, Pawel

Cyrus mailbox (plain files) to Dovecot
by Wolfgang Rosenauer 25 Sep '15

25 Sep '15

Hi, I'm migrating from a Cyrus to a Dovecot installation right now. As part of it I've got plain Cyrus mailboxes (w/o real metadata; so to say I've got the /var/spool/imap/user part but not the /var/lib/imap/user one)). Those former mailboxes I want to provide under a public namespace via ACLs. The question I cannot answer right now is: How can I convert these plain mailboxes on a FS level to maildir++ so I can provide them as public mailboxes on the new system? The tools I have found require a valid/complete cyrus mailbox. (I don't really care about message flags etc). Thanks, Wolfgang

v2.2.19 release candidate released
by Timo Sirainen 25 Sep '15

25 Sep '15

http://dovecot.org/releases/2.2/rc/dovecot-2.2.19.rc1.tar.gz http://dovecot.org/releases/2.2/rc/dovecot-2.2.19.rc1.tar.gz.sig A lot of changes since v2.2.18, so here's a release candidate first. If no bugs are reported, I'm planning on making the final release sometimes this week. The most interesting new features here are the imap-hibernate process, quota count backend and director/proxy improvements. * "doveadm director flush" command has a changed meaning now: It safely moves users to their wanted backends, instead of simply forgetting the mapping entirely and leaving the existing connections untouched. Use -F parameter to get the original unsafe behavior. + Added support for imap-hiberanate processes. + Optimized tracking mailboxes' vsizes (= sum of all messages' size). If mailbox_list_index=yes, it's also stored in there. This makes it very efficient to look up vsizes for all mailboxes. + Added a quota "count" backend, which uses the mailbox vsizes to get the current quota usage. It requires using the new quota_vsizes=yes setting, which tracks the messages' "virtual sizes" rather than "physical sizes". Their distiction is minor and mostly irrelevant nowadays (if mail sizes should be counted with LF or CRLF newlines). + "doveadm director up/down" commands added. The monitoring script should be using these commands instead of changing the vhost count. This allows admin to manually disable a server by changing the vhost count to 0 without the monitoring script changing it back. + Added support for HAProxy protocol: http://wiki2.dovecot.org/HAProxy + Added push-notification plugin framework, which can be used to easily implement push notifications to various backends. Implemented "ox" backend for notifying Open-Xchange via HTTP/json. + imap_logout_format supports more variables now, e.g. number of deleted messages. + pop3: Added pop3_delete_type setting (related to pop3_deleted_flag). + plugin { fts_enforced=yes } setting now fails body searches unless it can be done via the full text search engine. + Added %{passdb:*} and %{userdb:*} variables to various places + auth: Added ":protected" suffix for passdb and userdb fields. If used, the field doesn't overwrite an existing field. + IMAP/POP3 proxy: If a backend server dies, avoid client reconnection spikes by slowly disconnecting clients over time. This is enabled by setting login_proxy_max_disconnect_delay=secs passdb extra field. + imap: Added new read-only METADATA entries: /private/specialuse, /shared/comment, /shared/admin + imap: If client disconnects in the middle of a command, log how long the command had been running. - mdbox: Rebuilding could have caused message's reference count to overflow the 16bit number in some situations, causing problems when trying to expunge the duplicates. - Various search fixes (fts, solr, tika, lib-charset, indexer) - Various virtual plugin fixes - Various fixes and optimizations to dsync, imapc and pop3-migration - imap: Various RFC compliancy and crash fixes to NOTIFY

dovecot --hostdomain issue
by dovecot＠outputservices.com 25 Sep '15

25 Sep '15

I am on a server I called "email. But dovecot says i am on sunfire.outputservices.com ------------------------------------ dovecot --hostdomain sunfire.outputservices.com ------------------------------------ I would like to at least get it to say email.outputservices.com.

Released Pigeonhole v0.4.9.rc1 for Dovecot v2.2.19.rc1
by Stephan Bosch 25 Sep '15

25 Sep '15

Hello Dovecot users, Here's the Pigeonhole RC that goes with the Dovecot RC. Changelog v0.4.9.rc1: * Properly implemented checking of ABI version for Sieve interpreter plugins, much like Dovecot itself does for plugins. This will prevent plugin ABI mismatches. + Implemented a vnd.dovecot.environment extension. This builds upon the standard environment extension and adds a few more environment items, such as username and default mailbox. It also creates a variables namespace so that environment items can be accessed directly. I am still thinking about more environment items that can be added. + Sieve extprograms plugin: Made line endings of the input passed to the external programs configurable. This can be configured separately for each of the three extensions. + ManageSieve: Implemented proxy XCLIENT support. This allows the proxy to pass client information to the back-end. - ManageSieve: Fixed an assert failure occurring when a client disconnects during the GETSCRIPT command. - doveadm sieve plugin: Fixed incorrect initialization of mail user. This caused a few memory leaks. - sieve-filter command line tool: Fixed handling of failure-related implicit keep when there is an explicit default destination folder. This caused message duplication. - lib-sieve: Fixed bug in RFC5322 header folding. Words longer than the optimal line length caused empty lines in the output, which would break the resulting message header. This surfaced in References: headers with very long message IDs. The release is available as follows: http://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.9.rc1… http://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.9.rc1… 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

24 Sep '15

Hello, Im getting problem on FTS on new created folders (mailboxes). How to simulate: - Enable FTS (solr on our case) - Create a new folder (mailbox) - Move some message to that mailbox - Try to search for the message contents *doveadm search -u user@domain text sometext* # Found nothing, but if i move the message to another mailbox, the search catch the message. # I tried doveadm index command but no response as well # This works only after a full fts rescan *doveadm fts rescan -u user@domain* # And now, works *doveadm search -u user@domain text sometext3c7b60241443ba55af680000cc4d0d4b 1* # My dovecot version = 2.2.18 (EE) # My fts config: fts = solr fts_autoindex = yes fts_autoindex_max_recent_msgs = 50 fts_solr = url=http://127.0.0.1:8080/solr/ Anyone got this problem?

dict lookup from quota plugin
by Bjørnar Ness 23 Sep '15

23 Sep '15

I am having trouble with using a custom daemon listening on a socket together with the quota plugin. My configuration is: quota = dict:User quota::dict:/tmp/dovecot-proxy-dict:: The problem is that dovecot sends keys without usernames, for example: priv/quota/storage Is it possible to get around this limitation without code modification? Also, is it planned to support the "new-style" userdb/passdb lookups from other plugins? -- Bj(/)rnar

bug - over system quota and dovecot-uidlist
by krzf83＠gmail.com 23 Sep '15

23 Sep '15

Ever since I've migraded from courier pop3 to dovecot pop3 I'm constantly getting complains from users that went over system quota for short while and then their pop3 client downloads all messages again. I never happened with courier pop3. I think that dovecot does not handle dovecot-uidlist file safely so it can withstand such situations. rsync and other similar programs always writes to a copy of the file like dovecot-uidlis.xcb453 and on success unlinks old file and renames new one. Dovecot should not assume that write operation on dovecot-uidlist will succeed. Yes, I know I can put metadata like dovecot-uidlist somewhere else, on another partition but that really splits mailbox into multiple locations making for example backups way harder to make, restore, share etc.

Dovecot proxy ignores trusted root certificate store
by Alex Bulan 22 Sep '15

22 Sep '15

Dovecot v2.2.18 OS: FreeBSD 10.1/amd64 Dovecot in proxy mode ignores the root certificate store and can't verify the backend's SSL certificate. I've pointed ssl_client_ca_file to my root certificate store, but I suspect ssl_client_ca_file is only used in imapc context. It seems to be ignored in proxy context. doveconf -n ssl_client_ca_file: ssl_client_ca_file = /usr/local/share/certs/ca-root-nss.crt In my password_query I return host set to the backend's IP address, starttls='yes', proxy='y'. The backend's certificate chain is correct and it verifies successfully with "openssl s_client -connect x.x.x.x:110 -starttls pop3 -CAfile /usr/local/share/certs/ca-root-nss.crt". But the Dovecot proxy fails to verify the intermediate certificate it receives from the backend. The inode atime of ca-root-nss.crt is never updated, either at Dovecot start or when it connects to the backend, so Dovecot (via the openssl library) never reads the file.

2.2.18 Regression: Incorrect STATUS response for virtual mailboxes
by Guilhem Moulin 22 Sep '15

sieve_extprograms - run any individual script?
by Hajo Locke 22 Sep '15

22 Sep '15

Hello, i use sieve extension sieve_extprograms to send incoming mail to some script. For security reasons it is needed that script-paths etc. are registered in dovecot.conf This is my current dovecot.conf plugin { sieve = ~/.dovecot.sieve sieve_plugins = sieve_extprograms sieve_extensions = +vnd.dovecot.pipe +vnd.dovecot.filter +vnd.dovecot.execute sieve_pipe_bin_dir = /usr/local/bin/ sieve_filter_bin_dir = /usr/local/bin/ } .dovecot.sieve example: if address "to" "test(a)example.com" { filter "myfilter"; } This is all working without problems. Is there a possibility to allow users the execution of individual scripts in own homepath? Some people need to pipe mails to scripts for immediately processing (some ticketsystems need this). Is there a way to make this possible with sieve? Thanks, Hajo

Multiple passwords for a user (SQL)
by Marco Fretz 22 Sep '15

22 Sep '15

Hi everyone, I'm not sure if this has been discuessed already as I coun't find anything in the archives - maybe I'm looking for the wrong thing. I want to build something similar to googles "app passwords" where your use a different password (strong, auto generated) for each device / app. In general I think this is pretty easy on the database side as I just need a password table and link say the passwords with an user_id to the corresponding user in the users table - one use has many passwords (1:n). for dovecot this means that it will get multiple rows with passwords back from the "password_query". is there a way to tell dovecot to check all those returned passwords and "pass" the request if one of those passwords match? thank you, best regards Marco

[Dovecot] Pigeonhole sieve re-filter extension?
by T.B. 22 Sep '15

22 Sep '15

Dear Stephan Bosch, dear Dovecot community, "sieve-filter" re-filtering of existing mails is already a great progress for everyone using sieve! But as far as I know this functionality is just accessible by the server administrator. In the meanwhile everyone knows the comfort of re-executing filter scripts on his own existing mailboxes - triggered by himself! This service is already very widespread. Examples are MUA's like Outlook or Thunderbird which provide this service just on the client side. Or almost every web-mail provider offers this. Is there already an managesieve protocol extension that allows client triggered server side re-filtering? If not, maybe you could design a RFC for this? What do you think? Best regards. T.B.

ssl_key_password loaded from file: 'Couldn't parse private ssl_key'
by B. R. 22 Sep '15

22 Sep '15

As this is my first message to this ML: Hello! I am using a password-protected SSL key for my dovecot MDA. When I tried to use the ssl_key_password configuration directive as follow: ssl_key_password = </path/to/passfile it did not work as I logged the following: dovecot: imap-login: Error: SSL: Stacked error: error:06065064:digital envelope routines:EVP_DecryptFinal_ex:bad decrypt dovecot: imap-login: Fatal: Couldn't parse private ssl_key: error:0906A065:PEM routines:PEM_do_header:bad decrypt However, not using the fille inclusion but directly configuring as follow: ssl_key_password = mypass did work... I am loading my certificate & key with the file inclusion trick... How come cannot I use that for the password file? It would avoid input the password directly into the dovecot configuraiton files, forcing me to change permissions and duplicating it... When renewing the private key I will be force to edit the password at every location. Is it a bug? or a feature? :D --- *B. R.*

Messages lost from imap folders
by Nikolaos Milas 19 Sep '15

19 Sep '15

Hello, We have one user who is complaining that he has lost mails from 3 imap folders, administered through squirrelmail. The folders suddenly appeared unregistered, and once manually registered they were empty. Has anyone observed something like this? We are running two servers (as VMs) with Dovecot v2.2.18, synced (two-way) using dsync. The configurations follow. Can you please help me understand what may have gone wrong? Can I try to find actions regarding these folders in the logs? What should I search for? Could this be an issue involving dsync? How can I trace back dsync activity in detail? Server configs follow (I have only altered the real domain name and the login greeting.)

Is there a way to restrict my user logins from a set of IPs? For example, all my users are in the US so there shouldn't be any logins from other countries. Can I tell dovecot to restrict logins to a CIDR list of US IPs? Can someone point me to docs on how to set this up? I've searched but haven't found how to accomplish this. Thanks, -Terry Terry Barnum digital OutPost http://www.dop.com

New created users can not log in
by Ferdinand Gruber 17 Sep '15

17 Sep '15

Hi, I am using dovecot 2.2 for some time. All users on the system can log in using Horde Webmail. But now, after creating a new user on the server with <useradd -m username> this new user is not able to log in. Of course I have set a password for the new user. In the log file I can see: Sep 16 23:04:05 servername auth: gkr-pam: error looking up user information Sep 16 23:04:07 servername HORDE: [imp] [login] Authentication failed. [pid 1584 on line 730 of "/srv/www/htdocs/horde/imp/lib/Imap.php"] Sep 16 23:04:07 servername HORDE: [imp] FAILED LOGIN for calendar (93.82.157.132) to {imap://localhost/} [pid 1584 on line 157 of "/srv/www/htdocs/horde/imp/lib/Auth.php"] Sep 16 23:04:07 servername HORDE: [horde] FAILED LOGIN for calendar to horde (93.82.157.132) [pid 1584 on line 199 of "/srv/www/htdocs/horde/login.php"] Please give me a hint. -- Ferdinand

How to "Windows Authenticate"
by Mark Foley 17 Sep '15

17 Sep '15

I've been using Dovecot 2.2.15 as the IMAP server for Outlook (2010/2013) on Windows workstations for over 6 months with no problems. Dovecot is hosted on the office Samba4 AC/DC server. I have been using auth_mechanisms plain login, and passdb driver = shadow. What I'd like to do now is use the "Windows Authenticated" login so I don't have to have separate passwords for users logging into the Windows AD workstations and their Outlook clients. If anyone has actually done this I'd appreciate some tips. My various attempts have not been successful. Here is my current config: $ doveconf -n # 2.2.15: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 3.10.17 x86_64 Slackware 14.1 auth_debug_passwords = yes auth_mechanisms = plain login auth_verbose = yes auth_verbose_passwords = plain disable_plaintext_auth = no info_log_path = /var/log/dovecot_info mail_location = maildir:~/Maildir passdb { driver = shadow } protocols = imap ssl_cert = </etc/ssl/certs/OHPRS/GoDaddy/Apache/c5fe0cc8242d6030.crt ssl_key = </etc/ssl/certs/OHPRS/GoDaddy/mail.ohprs.org.key userdb { driver = passwd } verbose_ssl = yes Thanks, Mark Foley

FreeBSD 10 & default_vsz_limit causing reboots?
by Rick Romero 15 Sep '15

15 Sep '15

Ok, So this is really more of an observation than anything else. I had a FreeBSD 10.1 server that was running great. Some SSL issue came up, or I upgrade Dovecot in ports - something occurred and the machine started rebooting randomly. It would run for 2 weeks, then reboot. It might run for 5 days and then reboot. So I started doing more FreeBSD upgrades, thinking it was a kernel issue. The reboots only increased. This weekend I started thinking I might actually be having hardware issues. But, since I don't have easy physical access to the box and it's REALLY under loaded, I figured what the hell and upraded to 10.2 on Sunday. I think it rebooted 4 times after that on Sunday, and then another 2 times Monday morning. Its worth noting that while I have crash dumps enabled, they don't seem to be occurring. So hardware is still a possibility. After the 2nd Monday morning reboot, I started to wonder if there was some sort of process issue. Besides the OS upgrades - I had been monitoring the Dovecot logs for when the process limits are reached, and increasing them. It's a 'big' box, and load is typically between .30 and .50. CPUs aren't overtaxed, and most of the memory is dedicated to ZFS. The reboots are so short, I've only received one 'down' alert due to them. So it's a conerning issue, but not really impacting production. On a whim I changed my default_vsz_limit (as I had been increasing every other limit but that) from 384M to 512M. The system hasn't rebooted in 24hours. Now that could be a coincidence, but I thought I'd at least put it out there. If you see anything weird in my dovecot config, let me know - My config was originally vpopmail, but over time I've migrated to SQL-only. root@romulus:/usr/local/etc/dovecot # dovecot -n # 2.2.18: /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 10.2-RELEASE amd64 auth_master_user_separator = * auth_mechanisms = plain login auth_username_translation = %@ auth_verbose = yes default_login_user = dovecot default_vsz_limit = 512 M disable_plaintext_auth = no first_valid_gid = 89 first_valid_uid = 89 last_valid_gid = 89 last_valid_uid = 89 log_path = /dev/stderr login_greeting = Ready. login_trusted_networks = 172.16.100.0/24 mail_fsync = never mail_plugins = " quota zlib stats" mail_privileged_group = mail namespace compat { alias_for = hidden = yes inbox = no list = no location = prefix = INBOX. separator = . } namespace inbox { inbox = yes location = prefix = separator = . } passdb { args = /usr/local/etc/dovecot/dovecot-master-sql.conf driver = sql master = yes pass = yes } passdb { args = /usr/local/etc/dovecot/dovecot-sql.conf driver = sql } plugin { quota = maildir quota_rule = Trash:storage=+10%% stats_refresh = 30 secs stats_track_cmds = yes } protocols = imap pop3 service anvil { client_limit = 3175 } service auth { client_limit = 3684 unix_listener auth-master { mode = 0600 } } service imap-login { process_limit = 1536 process_min_avail = 25 service_count = 1 } service imap-postlogin { executable = script-login rawlog /usr/local/etc/dovecot/lastauth-imap.sh user = vpopmail } service imap { executable = /usr/local/libexec/dovecot/imap imap-postlogin process_limit = 1536 } service pop-postlogin { executable = script-login /usr/local/etc/dovecot/lastauth-pop.sh user = vpopmail } service pop3-login { process_limit = 1536 process_min_avail = 15 service_count = 1 } service pop3 { executable = /usr/local/libexec/dovecot/pop3 pop-postlogin } service stats { fifo_listener stats-mail { mode = 0600 user = vpopmail } } shutdown_clients = no ssl_cert = </etc/ssl/mail.pem ssl_key = </etc/ssl/mail.key ssl_key_password = na userdb { driver = prefetch } verbose_proctitle = yes protocol imap { imap_client_workarounds = delay-newmail tb-extra-mailbox-sep mail_max_userip_connections = 100 mail_plugins = " quota zlib stats imap_zlib quota imap_quota" } protocol pop3 { mail_max_userip_connections = 100 mail_plugins = quota pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_uidl_format = %08Xu%08Xv }

Dovecot does not accept new connection with error "imap-login: Error: read(anvil) failed: EOF"
by Julien Fastré 14 Sep '15

14 Sep '15

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hi, First of all, thank you for the work the contributors are doing with Dovecot ! Dovecot is doing a great job ! I am encountering a problem with a configuration and, despite my search on the web, I do not find any solution for this problem. Dovecot seems to stop accepting new connection. The users : - - can not save sent messages to "Sent" folder (using Thunderbird) ; - - can not connect or retrieve message from webmail (using sogo or roundcube) In the log, I see this error : > Jun 30 13:54:53 mail dovecot: imap-login: Error: read(anvil) > failed: EOF Jun 30 13:54:53 mail dovecot: message repeated 2 times: > [ imap-login: Error: read(anvil) failed: EOF] (the message may be repeated more than 2 times) It happens... sometimes. Manually restarting the dovecot service make the software working again. By searching on the web, I regularly see this statement in logs : > dovecot: auth: Error: read(anvil-auth-penalty) failed: EOF like here : http://www.dovecot.org/list/dovecot/2010-November/054694.htm l But it doesn't seem to be the same problem as mine (anvil / anvil-auth-penalty). The problem happens during peak load. Sometimes it happens twice a week, sometimes it may spent two month without any problem (during holidays, I did not had any problem). My configuration : > # doveconf -n # 2.2.9: /etc/dovecot/dovecot.conf # OS: Linux > 3.13.0-49-generic x86_64 Ubuntu 14.04.3 LTS login_trusted_networks > = 10.0.3.0/24 mail_location = mbox:~/mail:INBOX=/var/mail/%u > mail_plugins = quota acl managesieve_notify_capability = mailto > managesieve_sieve_capability = fileinto reject envelope > encoded-character vacation subaddress comparator-i;ascii-numeric > relational regex imap4flags copy include variables body enotify > environment mailbox date ihave namespace { list = children location > = maildir:/var/mail-data/vhosts/%%u:INDEX=~/shared/%%u prefix = > shared/%%u/ separator = / subscriptions = no type = shared } > namespace inbox { inbox = yes location = mailbox Drafts { > special_use = \Drafts } mailbox Junk { special_use = \Junk } > mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { > special_use = \Sent } mailbox Trash { special_use = \Trash } prefix > = separator = / type = private } passdb { driver = pam } passdb { > args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { > acl = vfile acl_shared_dict = > file:/var/mail-data/acl_db/shared-mailboxes quota = maildir:User > quota quota_grace = 10%% quota_rule = *:storage=2G quota_rule2 = > Trash:storage=+100M sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } > postmaster_address = julienfastre(a)cvfe.be protocols = " imap lmtp > sieve" service auth { unix_listener > /var/spool/postfix/private/dovecot-auth { group = postfix mode = > 0660 user = postfix } } service lmtp { unix_listener > /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = > 0600 user = postfix } } ssl_ca = </etc/dovecot/certificates/ca.pem > ssl_cert = </etc/dovecot/certificates/mail.cert.pem ssl_key = > </etc/dovecot/certificates/mail.key.nopass.pem userdb { driver = > passwd } userdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver > = ldap } protocol lmtp { mail_plugins = quota acl sieve } protocol > imap { mail_max_userip_connections = 30 mail_plugins = quota acl > imap_quota imap_acl } As somes answer about anvil-auth-penalty may suggest it is linked with proc capabilities, this is the limitation of the /proc > root@mail:/home/ubuntu# ps -aux | grep anvil postfix 4568 0.0 > 0.0 27404 1596 ?

Need help on checkpassword userdb/passdb
by Mark Foley 13 Sep '15

13 Sep '15

I'm experimenting with checkpassword as an auth method for usedb and passdb (http://wiki2.dovecot.org/AuthDatabase/CheckPassword) I've set up the userdb and passdb *exactly* as the wiki suggests as the "standard way": passdb { driver = checkpassword args = /user/util/bin/checkpassword } userdb { driver = prefetch } I've created a checkpassword program that does receive the correct user and password from dovecot. And I am successfully authenticating with ntlm_auth and exiting with status 0. My debug output: AUTHORIZED: (null) USER: (null) userdb_uid: (null) userdb_gid: (null) arg1=/usr/local/libexec/dovecot/checkpassword-reply CMD: /usr/bin/ntlm_auth --username="mark" --password='mypass' ntlm_auth status: 0 Now, the wiki says 2 things that have me stumped: 1. It says that, "Dovecot calls the script with AUTHORIZED=1 environment set when performing a userdb lookup. The script must acknowledge this by changing the environment to AUTHORIZED=2, otherwise the lookup fails." As you can see from my program log, "AUTHORIZED" is not set. Why? Nor are any of the other environment variables mentioned in the wiki. I've listed all the environment variables that *are* passed to the program at the bottom of this message. 2. The wiki says, "Your program received a path to checkpassword-reply binary as the first parameter. Execute it." I did so as a fork() and then execve("/usr/local/libexec/dovecot/checkpassword-reply") How do I know it worked ... or failed? What am I doing wrong?

Dovecot CalDAV server
by Timo Sirainen 11 Sep '15

11 Sep '15

I've been once in a while over the years thinking about implementing CalDAV (and CardDAV) to Dovecot. It might be time to start that soon. Does anyone have any suggestions? So far my main goals would be: - scalable, of course - configurable storage (object storage, regular fs, maybe some key-value dbs, maybe storing as emails) - efficient indexes (potentially using key-value dbs? or maybe just local files. not sure yet what kind of indexing is needed) - have it work with dsync (= replication & migration) Some things I wonder about: - Maybe there is already some code out there that could be used to implement it faster? - Maybe even use something else besides C to implement it.. Then again that makes integration to Dovecot more difficult. - Is anybody interested in helping to develop this? :) I think I still have too much other work that I won't spend a lot of time coding it.. One thing that makes this easier is that Open-Xchange has already implemented a CalDAV server, so they can help to avoid the biggest design mistakes. (There are a couple of reasons why they'd want to replace that.)

My dovecot works fine against Active Directory 2003, but not against AD2008
by Fran 10 Sep '15

10 Sep '15

Hello, my dovecot installation has been working fine against AD till we upgrade from AD 2003 to AD 2008. As http://wiki2.dovecot.org/AuthDatabase/LDAP said, now I'm not able to connect AD through 389 port. The port 3268 works fine though. (...) Sep 7 19:02:05 <dovecotServer> dovecot: imap-login: Error: master(imap): Auth request timed out (received 0/12 bytes) Sep 7 19:02:05 <dovecotServer> dovecot: imap-login: Internal login failure (pid=4846 id=1) (internal failure, 1 successful auths): user=<<username>>, method=PLAIN, rip=<clientLAN_IP>, lip=<dovecotServer_IP>, TLS, session=<T+grMCsfqgAKHyZV> (...) Sep 7 19:02:06 <dovecotServer> dovecot: auth: Error: ldap(<username>,<clientLAN_IP>,<ZjyONSsf6QAKHyZV>): Connection appears to be hanging, reconnecting Sep 7 19:02:06 <dovecotServer> dovecot: auth: Error: ldap(<username>,<clientLAN_IP>,<T+grMCsfqgAKHyZV>): LDAP search returned multiple entries (...) Is there a technical reason for this problem? Does it exist any workaround? The use of Global Catalog (port 3268) is not a solution for me, since it misses many attributes. (ex. I use the field "initials" to set the quota and this field is not available through port 3268). I also noticed that, now, it uses any DC available in the domain, it doesn't care what I configured in "hosts = " parameter. This is using "hosts = dc03.domain:389": ----------------------------------------------- [root@<dovecotServer> ~]# netstat -anp | grep dovecot | grep auth tcp 22 0 <dovecotServer_IP>:55217 <dc03.domain_IP>:389 ESTABLISHED 4872/dovecot/auth tcp 22 0 <dovecotServer_IP>:57645 <dc06.domain_IP>:389 ESTABLISHED 4872/dovecot/auth tcp 0 0 <dovecotServer_IP>:55216 <dc03.domain_IP>:389 ESTABLISHED 4872/dovecot/auth It looks like it does a look up for other domains controller (I don't know how nor why) and it connect aleatory to any DC in my domain (in this case dc06.domain, but it changes any time), additionally to the configured one (dc03.domain). This is using "hosts = dc03.domain:3268": ------------------------------------------------ [root@<dovecotServer> ~]# netstat -anp | grep dovecot | grep auth tcp 0 0 <dovecotServer_IP>:58485

Convert from Maildir to Mdbox
by J. Echter 09 Sep '15

09 Sep '15

Hi, i'd like to convert from maildir to mdbox. what would be the best way to do this? i have read the dsync part of the dovecot wiki but i don't get what i have to use for my setup. my dovecot.conf (the snippets i think would matter): mail_gid = 5000 mail_home = /DATEN/vmail/%d/%n mail_location = maildir:/DATEN/vmail/%d/%n/mail/ mail_plugins = " zlib" mail_uid = 5000 Thanks for your input.

[Dovecot] dsync replication errors
by Oli Schacher 09 Sep '15

09 Sep '15

Hi I'm trying to build a cluster of two servers with dsync replication (based on http://wiki2.dovecot.org/Replication) My test setup works fine for very simple tests, I can log in to both servers, copy a message to one of the servers and it successfully apperars in the other account. But, if I try to copy a large amount of messages at once to one of the accounts, my maillogs get flodded with errors(see below) and the mailboxes seem to get out of sync and messages are duplicated over and over again (I originally copied 100 messages and ended up with thousands in both mailboxes until I killed dovecot) I'd appreciate if someone could have a look at my config and tell me what I did wrong. dovecot.conf of both servers, they are identical except for the target ip in mail_replica: dovecot -n # 2.2.beta1 (070ca24e5846+): /etc/dovecot/dovecot.conf # OS: Linux

sieve_extprograms - double linebreaks at filtering
by Hajo Locke 09 Sep '15

09 Sep '15

Hello List, i have a problem when using sieve-plugin sieve_extprograms. I use dovecot 2.2.18 and bundled pigeonhole 0.4.6 (Ubuntu 14.04.3 LTS) i have enabled sieve_extprograms and vnd.dovecot.filter to send mail to user-defined script and get changed content back. My script previously was used with procmail and is working fine. Using same script with vnd.dovecot.filter leads to odd behavior. I already found out the problem itself: By sending Mailcontent to filter-programm it seems that sieve/sieve_extprograms is adding additional linebreaks to every line of complete mail. Please see this image to clarify: http://r31i.imgup.net/header8d56.jpg?l=de Every lineending got additional windows-lineendings, which leads to problems with processing scripts. Piping mails by procmail to same script is working without problems, because this mails are recieved "clean" without the "^M". this is part of dovecot.conf: plugin { sieve = ~/.dovecot.sieve sieve_plugins = sieve_extprograms sieve_extensions = +vnd.dovecot.pipe +vnd.dovecot.filter +vnd.dovecot.execute sieve_pipe_bin_dir = /usr/local/bin/ sieve_filter_bin_dir = /usr/local/bin/ } this is part of userscript ~/.dovecot.sieve: require ["fileinto", "vacation", "variables", "envelope", "imap4flags", "vnd.dovecot.filter", "subaddress"]; if address "to" "test2(a)example.com" { filter "my-script"; } my-script currently just recieves and saves raw-data, so i could find difference between sieve and procmail mails. What to do here? Is this a kind of bug of sieve/sieve_extprograms or i have to use additional parameters? Thanks, Hajo

Problems setting up SIS (duplicate files with same hash)
by Joe Beaubien 09 Sep '15

09 Sep '15

Hi everyone, I am currently trying to setup our next dovecot server (2.2.18) with SIS enabled, but I have enconutered 1 problem and 1 question: *1) Same attachment, different filenames* I have a feeling a misconfigured something (or forgot to do something) because SIS almost works, but not quite since 3 identical attachment take 3x the space (see end of email for my SIS config). For 3 the emails I sent with the same attachment, I got 3 seperate files with the same hash name but a different string following the dash: -rw------- 1 info info 2.6M Sep 5 11:14 e35083e3280a21c6aaabbae8cb23d54493f514a5-6a22711a7b05eb5509480000045c9bf4 -rw------- 1 info info 2.6M Sep 5 11:16 e35083e3280a21c6aaabbae8cb23d54493f514a5-6c22711a7b05eb5509480000045c9bf4 -rw------- 2 info info 2.6M Sep 5 11:18 e35083e3280a21c6aaabbae8cb23d54493f514a5-6e22711a7b05eb5509480000045c9bf4 drwx------ 2 info info 4.0K Sep 5 11:18 hashes For the record, the "hashes" subfolder has only 1 hash (e35083e3280a21c6aaabbae8cb23d54493f514a5) which perfectly matches the first part of the 3 filenames. *2) Saving attachments under a generic name or more flexible permissions?* It seems that dovecot saves the attachment with the username and group of the user who has received the email. Is it possible to have dovecot save the attachments as a generic user (like dovecot or dovenull) so that all my different users can share the same pool of attachments? Alternatively, is it possible to have dovecot save the attachment under more flexible permissions so that they can be shared between users? This would allow us to save alot of disk space. *Here is the SIS config I am using:* mail_attachment_dir = /data/emails/attachments #mail_attachment_min_size = 128k #mail_attachment_fs = sis posix #mail_attachment_hash = %{sha1} Any help would be very much appreciated. Thank you, Joe B

Dovecot and IPA
by Kanwar Ranbir Sandhu 08 Sep '15

08 Sep '15

Hello, I'm trying to get Dovecot to use GSSAPI for authentication. I have an IPA server on CentOS 7 with a bunch of my servers attached to the IPA domain, including the server running Dovecot. I've followed official documentation from Red Hat and read numerous wiki articles on how to configure Dovecot to get it to use GSSAPI correctly. I don't think I've done anything incorrectly, but it refuses to work. This is the error I'm seeing: mailman02 dovecot: imap-login: Disconnected (tried to use unsupported auth mechanism): user=<>, method=PLAIN, rip=1.1.1.1, lip=2.2.2.2, TLS, session=<QhWSqxofyAAKyAkM> I don't understand why no username is being passed. My mail client is Evolution 3.10.4. FYI, Dovecot does work fine using a user/password file. I'm just trying to switch it over to GSSAPI so that I can manage passwords from one system. Any help would be appreciated. Regards, Ranbir -- Kanwar R.S. Sandhu

Multiple vacation
by Michele Locati 08 Sep '15

08 Sep '15

Hi all I'm using Dovecot 2.2.9 and I'm having problems configuring multiple vacation actions. The problem is that I'd like to have two different senders and two different messages, selecting the correct case by the recipient email address. I mean, if someone writes me to my email address "to-address1(a)example.com" I'd like to answer from "from-address1(a)example.com" with the message "TEST 1". If someone writes me to my email address "to-address2(a)example.com" I'd like to answer from "from-address2(a)example.com" with the message "TEST 2". Here's my script: require ["fileinto","vacation"]; vacation :addresses ["to-address1(a)example.com"] :from " from-address1(a)example.com" text: TEST 1 . ; } vacation :addresses ["to-address2(a)example.com"] :from " from-address2(a)example.com" text: TEST 2 . ; But the vacation filter doesn't work, and I see this message in the log file: main script: line X: error: duplicate vacation action not allowed (previously triggered one was here: main script: line Y). Is there a way to allow multiple vacation actions? Thank you Michele

Public folder subscriptions with Outlook
by Paul Tansom 08 Sep '15

08 Sep '15

This is more an Outlook issue than Dovecot, but given that it is connected to Dovecot I figured there would be a good pool of knowledge here that increases the likelihood that somebody knows the answer :) I have a Dovecot server setup with a public folder and keep getting complaints that Outlook users don't see new folders created by other people. In Thunderbird it is simply a case of unchecking the box to only show subscribed folders, but I can't find a way to do this in Outlook. The only thing I can think of is putting a script on the server to check for new folders and update each users subcriptions file, but I'm not completely happy with that solution! Any suggestions welcome. -- Paul Tansom | Aptanet Ltd. | https://www.aptanet.com/ | 023 9238 0001 Vice Chair, FSB Portsmouth & SE Hampshire Branch | http://www.fsb.org.uk/ ============================================================================= Registered in England | Company No: 4905028 | Registered Office: Ralls House, Parklands Business Park, Forrest Road, Denmead, Waterlooville, Hants, PO7 6XP

Different behavior of ACLs in MUA and doveadm
by Thomas Leuxner 08 Sep '15

08 Sep '15

I have noticed a difference in the behavior of ACLs. When used in a MUA the following global ACL works fine and has the desired effect - new mailboxes can be created by a user being part of the 'PublicMailboxAdmins' group: [ global-acl: ] INBOX owner lrwstiekxap Public/* group=PublicMailboxAdmins lrwsipk Public/* anyone lr Public/* authenticated lrws Creating the same mailbox via doveadm however fails with a permission problem: doveadm(tlx(a)leuxner.net): Debug: acl vfile: Global ACL file: /var/vmail/conf.d/leuxner.net/global-acl doveadm(tlx(a)leuxner.net): Debug: Namespace : type=public, prefix=Public/, sep=/, inbox=no, hidden=no, list=yes, subscriptions=no location=mdbox:/var/vmail/public:INDEXPVT=~/mdbox/public doveadm(tlx(a)leuxner.net): Debug: fs: root=/var/vmail/public, index=, indexpvt=/var/vmail/domains/leuxner.net/tlx/mdbox/public, control=, inbox=, alt= doveadm(tlx(a)leuxner.net): Debug: acl: initializing backend with data: vfile:/var/vmail/conf.d/leuxner.net/global-acl:cache_secs=300 doveadm(tlx(a)leuxner.net): Debug: acl: acl username = tlx(a)leuxner.net doveadm(tlx(a)leuxner.net): Debug: acl: owner = 0 doveadm(tlx(a)leuxner.net): Debug: acl vfile: Global ACL file: /var/vmail/conf.d/leuxner.net/global-acl doveadm(tlx(a)leuxner.net): Debug: Namespace : type=private, prefix=Virtual/, sep=/, inbox=no, hidden=no, list=yes, subscriptions=yes location=virtual:~/mdbox/virtual doveadm(tlx(a)leuxner.net): Debug: fs: root=/var/vmail/domains/leuxner.net/tlx/mdbox/virtual, index=, indexpvt=, control=, inbox=, alt= doveadm(tlx(a)leuxner.net): Debug: acl: initializing backend with data: vfile:/var/vmail/conf.d/leuxner.net/global-acl:cache_secs=300 doveadm(tlx(a)leuxner.net): Debug: acl: acl username = tlx(a)leuxner.net doveadm(tlx(a)leuxner.net): Debug: acl: owner = 1 doveadm(tlx(a)leuxner.net): Debug: acl vfile: Global ACL file: /var/vmail/conf.d/leuxner.net/global-acl doveadm(tlx(a)leuxner.net): Debug: acl vfile: file /var/vmail/public/mailboxes/dovecot-acl not found doveadm(tlx(a)leuxner.net): Error: Can't create mailbox Public/Archive/Newsletters/heise-security/2014: Permission denied Interestingly, doveadm succeeds when dovecot-acl is present in the namespace root - which of course is not desirable in the light of the global ACL: [ dovecot-acl: ] group=PublicMailboxAdmins lrwsipk doveadm(tlx(a)leuxner.net): Debug: acl vfile: Global ACL file: /var/vmail/conf.d/leuxner.net/global-acl doveadm(tlx(a)leuxner.net): Debug: Namespace : type=public, prefix=Public/, sep=/, inbox=no, hidden=no, list=yes, subscriptions=no location=mdbox:/var/vmail/public:INDEXPVT=~/mdbox/public doveadm(tlx(a)leuxner.net): Debug: fs: root=/var/vmail/public, index=, indexpvt=/var/vmail/domains/leuxner.net/tlx/mdbox/public, control=, inbox=, alt= doveadm(tlx(a)leuxner.net): Debug: acl: initializing backend with data: vfile:/var/vmail/conf.d/leuxner.net/global-acl:cache_secs=300 doveadm(tlx(a)leuxner.net): Debug: acl: acl username = tlx(a)leuxner.net doveadm(tlx(a)leuxner.net): Debug: acl: owner = 0 doveadm(tlx(a)leuxner.net): Debug: acl vfile: Global ACL file: /var/vmail/conf.d/leuxner.net/global-acl doveadm(tlx(a)leuxner.net): Debug: Namespace : type=private, prefix=Virtual/, sep=/, inbox=no, hidden=no, list=yes, subscriptions=yes location=virtual:~/mdbox/virtual doveadm(tlx(a)leuxner.net): Debug: fs: root=/var/vmail/domains/leuxner.net/tlx/mdbox/virtual, index=, indexpvt=, control=, inbox=, alt= doveadm(tlx(a)leuxner.net): Debug: acl: initializing backend with data: vfile:/var/vmail/conf.d/leuxner.net/global-acl:cache_secs=300 doveadm(tlx(a)leuxner.net): Debug: acl: acl username = tlx(a)leuxner.net doveadm(tlx(a)leuxner.net): Debug: acl: owner = 1 doveadm(tlx(a)leuxner.net): Debug: acl vfile: Global ACL file: /var/vmail/conf.d/leuxner.net/global-acl doveadm(tlx(a)leuxner.net): Debug: acl vfile: reading file /var/vmail/public/mailboxes/dovecot-acl doveadm(tlx(a)leuxner.net): Debug: Namespace Public/: /var/vmail/public/mailboxes/Archive/Newsletters/heise-security/2014 doesn't exist yet, using default permissions doveadm(tlx(a)leuxner.net): Debug: Namespace Public/: Using permissions from /var/vmail/public: mode=0700 gid=default doveadm(tlx(a)leuxner.net): Debug: acl vfile: file /var/vmail/public/mailboxes/Archive/Newsletters/heise-security/dbox-Mails/dovecot-acl not found doveadm(tlx(a)leuxner.net): Debug: acl vfile: file /var/vmail/public/mailboxes/Archive/Newsletters/heise-security/2014/dbox-Mails/dovecot-acl not found doveadm(tlx(a)leuxner.net): Debug: acl vfile: file /var/vmail/public/mailboxes/Archive/Newsletters/heise-security/2014/dbox-Mails/dovecot-acl not found doveadm(tlx(a)leuxner.net): Debug: acl vfile: file /var/vmail/public/mailboxes/Archive/Newsletters/heise-security/2014/dbox-Mails/dovecot-acl not found # 2.2.15 (6078354e6238): /etc/dovecot/dovecot.conf I know there have been some changes in Mercurial as to how global ACLs are interpreted. Is doveadm probably behind on them? Regards Thomas

Fetch command response questions
by Vlad Pop 08 Sep '15

08 Sep '15

Hello, I have the following issue: When using command FETCH 2 (BODY.PEEK[HEADER] UID INTERNALDATE FLAGS BODYSTRUCTURE) on 2 different emails, we get 2 different response structure. First response structure contains the BODYSTRUCTURE in a single line, while in the second response, the BODYSTRUCTURE is divided into multiple lines with "{61}" character at the end of each line. The difference between those 2 emails is the name of some attachments. The attachment is an .eml file named "Re: [SR-Users] Keep-Alive in dialog "freeing a free fragment"" Is this a sort of bug or is it correct to receive the BODYSTRUCTURE on multiple lines? Vlad Pop

segfault when using zlib module with glibc 2.22
by Florian Pritz 08 Sep '15

08 Sep '15

Hi, I'm seeing the following segfault when I run `doveadm search mailbox inbox` with the zlib module enabled with dovecot 2.18 and glibc 2.22 on Arch Linux. It does not happen with glibc 2.21. I've noticed that when I remove "zlib" from the mail_plugins line at the beginning of the config file the segfault goes away. I've also tested hg tip and the problem does not appear to be fixed yet. The segfault also happens with other commands like `doveadm purge`. Do you need any more information to reproduce and fix this?

File permissions: system groups for do not work for group/shared mailboxes
by Jens Kirchner 08 Sep '15

08 Sep '15

Hello! I am struggling to set up a group mailbox for users of a certain system group. I want to grant access to the mailbox on a filesystem mode by using the system groups. The problem, the set up works fine and when I use setfacl and grant permissions too each user manually, it works fine. However, I want to use a system user's group membership in order to grant access to these mailboxes insted of manually granting for each user. dovecot version: 2.2.9 This is the config part: namespace { location = maildir:/data/mail/public:LAYOUT=fs prefix = GROUP-MAILBOXES/ separator = / subscriptions = no type = public } ... passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } ... userdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } filesystem permissions (getfacl): # file: GroupboxA/ # owner: root # group: root user::rwx user:user1:rwx group::rwx mask::rwx other::--- default:user::rwx default:user:user1:rwx default:group::rwx default:mask::rwx default:other::--- # file: GroupboxB/ # owner: root # group: root user::rwx group::rwx group:group1:rwx mask::rwx other::--- default:user::rwx default:group::rwx default:group:group1:rwx default:mask::rwx default:other::--- user1 is in roup1 When setting username-based permissions (GroupboxA), the mailbox is usable and subsribable; when setting groupname-based permissions (GroupboxB) it is not subscribable/usable. Thanks for your help in advance and best regards, Jens

bug in acl_defaults_from_inbox option
by Marco Giunta 08 Sep '15

08 Sep '15

Hi at all, there is a bug in in acl_defaults_from_inbox option: if you define it with ANY value ('yes', 'no', 'whatyouwant', 'xxx') it acts like the value is ALWAYS 'yes', and Dovecot enable it; the only way to disable it, is comment it or delete from configuration file. With 'acl_defaults_from_inbox = no', or 'acl_defaults_from_inbox = whatyouwant', all my folders get ACLs from INBOX; in my case I want to only share INBOX, but also all other folders were shared. When you comment 'acl_defaults_from_inbox', Dovecot works like expected.

Patch for "doveadm -f table" nit (was Re: Dovecot current number of connections being used.)
by Joseph Tam 08 Sep '15

08 Sep '15

> doveadm who -1 2>/dev/null | wc -l You have to redirect stderr to /dev/null because that's where the first header line is written to. The default format style (table) is inconsistent with the other formats (flow,pager,tab) that write headers and data to stdout. The following patch will pick this nit. This patch will require modifications to scripts that rely on doveadm writing headers to stderr. For example, the above doveadm command could be modified to doveadm who -1 | grep -vc '^username' -------------------------------------------------------------------------------- --- a/dovecot-2.2.16.rc1/src/doveadm/doveadm-print-table.c Wed Mar 18 15:40:40 2015 +++ b/dovecot-2.2.16.rc1/src/doveadm/doveadm-print-table.c Wed Mar 18 15:41:18 2015 @@ -151,3 +151,3 @@ for (i = 0; i < count; i++) { - if (i > 0) fprintf(stderr, " "); + if (i > 0) printf(" "); @@ -155,3 +155,3 @@ DOVEADM_PRINT_HEADER_FLAG_RIGHT_JUSTIFY) == 0) { - fprintf(stderr, "%-*s", (int)headers[i].length, + printf("%-*s", (int)headers[i].length, headers[i].title); @@ -158,3 +158,3 @@ } else { - fprintf(stderr, "%*s", (int)headers[i].length, + printf("%*s", (int)headers[i].length, headers[i].title); @@ -162,3 +162,3 @@ } - fprintf(stderr, "\n"); + printf("\n"); } -------------------------------------------------------------------------------- Joseph Tam <jtam.home(a)gmail.com>

Re: Null deference pointer in dovecot-2.2.18
by 吴迪 08 Sep '15

08 Sep '15

Dear, use our static analysis tools, I find some bugs (Null deference pointer) for dovecot-2.2.18. Null deference pointer bugs often make program crashes, Please confim them, Thanks! 1. dovecot-2.2.18/src/config/config-request.c 332 'setting_export_section_name(ctx->prefix, def, children[i], i);', pointer 'children' in line 202 assigned NULL and if branch 'case SET_DEFLIST_UNIQUE' not execute, so pointer 'children' is always NULL. It load to a bug of null deference pointer In line 332. The same bugs also appeared in : 1. dovecot-2.2.18/src/lib-index/mail-index-fsck.c line 170 or 174, pointer 'kw_rec ' mybe NULL. 2.dovecot-2.2.18/src/lib-storage/mail-search-args-simplify line 349, pointer 'prev_arg' mybe NULL. best wishes~ Amy
