Dovecot authentication LDAP SSL-TLS againts SAMBA4
by Lista de Dovecot 22 Aug '14

22 Aug '14

Hi, i would like to know if anybody have implemented the authentication of dovecot against samba4 via secure ldap (SSL/TLS). I made it but in plain text through dovecot´s offical page: http://wiki2.dovecot.org/AuthDatabase/LDAP/AuthBinds http://wiki2.dovecot.org/AuthDatabase/LDAP But when i try to do it in a secure way i can´t make it work. Samba4 is listening by port 636 and dovecot is speaking by 389 or 636, but they can´t comunicate themself. I´m wondering if any of you have done this before or have any clue that might help me. Thanks.

Avoid "451 4.4.0 Remote server not answering (timeout while waiting for reply to DATA reply)"
by Florent Bautista 22 Aug '14

22 Aug '14

Hi all, I have a Dovecot setup (2.1, I will switch to 2.2 soon) with one Director and 2 backend servers. When my MX server (Postfix) tries to deliver mail to Dovecot via LMTP, it often gets an error "451 4.4.0 Remote server not answering (timeout while waiting for reply to DATA reply)" from the Director. Service LMTP is configured with "client_limit = 1" on Director en backends (others limits are default ones). Postfix is using "lmtp_destination_recipient_limit = 1" and "lmtp_destination_concurrency_limit = 1". I want that incoming messages are stored one after one per recipient (have a queue per recipient). I does not seem to be done actually. I think Postfix is sending too many messages at a time to Director. How do you do to handle that ? I already applied the 3 patches available on the list for 2.1, but it does not seem to solve my problem... Thank you a lot. Florent

Folders don't show up
by Christian Hudon 22 Aug '14

22 Aug '14

Hello, I've upgraded to the new LTS version of Ubuntu. With that comes a new dovecot version. I think I've migrated my dovecot configuration correctly to the new version. Everything works, except that the mailboxes don't show up in the list of mailboxes in my mail clients. Trying to issue a LIST command, I see the following: CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE STARTTLS AUTH=PLAIN] Dovecot (Ubuntu) ready. 1 login USERNAME_HERE PASSWORD_HERE 1 OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS THREAD=ORDEREDSUBJECT MULTIAPPEND URL-PARTIAL CATENATE UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS SPECIAL-USE BINARY MOVE] Logged in 2 LIST "" "*" * LIST (\HasNoChildren) " * LIST (\HasNoChildren) " [SNIP...

I'm not an IMAP protocol expert, but those answers to the list command don't quite look like valid IMAP to me. My imapdir has a bunch of maildir directories in it, like a normal imapdir should. Everything worked fine with the previous version of dovecot (1.2?). Maybe a dovecot bug? At least I don't see how my config could cause this. Any help would be appreciated.

Thunderbird not able to edit sieve Message Filters
by Peter Bell 22 Aug '14

22 Aug '14

I'm not sure when this problem first occurred - it is many months since I last editted a sieve filter. I am certainly several versions of Thunderbird and, probably, a few versions of Dovecot on from when I last editted a sieve filter. However, I do know that I have done so in the past. I have just built Dovecot 2.2.13 and Pigeonhole 0.4.3, installed and running on Slackware 14.1 x64. I am running an up-to-date version of Thunderbird (31.0) on Arch Linux x64. The sieve filters are definitely being applied to incoming mail, and working perfectly well. However, when I attempt to edit the Sieve Filters (from Thunderbird Tools->Sieve Message Filters...), the Sieve Filters tab is displayed, but not populated (eg, the Server Sieve Capabilities are not displayed, and there is an endless 'hourglass' displayed in the main mailfilters pane. Does anyone recognise the symptoms and can advise how to resolve the problem, or suggest what logs I should examine/post in order to identify the cause? -- ------------------------------------------------------------------- Peter Bell Mob: +63 (0) 9287 340 343 Tagum City, Philippines.

Assertion in istream.c::167 in POP3 mode when maildir content has wrong S value (using 2.2.13)
by Rolf Eike Beer 21 Aug '14

21 Aug '14

Hi, the affected machine is running 2.2.13 on Gentoo x86_64. For me it looks like the old size is still in some struct or whereever even after the file has been renamed. I see that there are many commits following 2.2.13, is that possibly already fixed or do I need to dig in the code? The original problem seems to be that maildrop uses the file size before piping the mail into spamassassin even if the mail is bigger afterwards. Not relevant here, but in case anyone wonders how this happens. Greetings, Eike Error: Cached message size smaller than expected (81118 < 81308) Error: Maildir filename has wrong S value, renamed the file from /var/vpopmail/domains/example.org/user/.maildir/cur/1408452738.16341.mail,S=81118:2, to /var/vpopmail/domains/example.org/user/.maildir/cur/1408452738.16341.mail,S=81308:2, Error: Corrupted index cache file /var/vpopmail/domains/example.org/user/.maildir/dovecot.index.cache: Broken physical size for mail UID 65 Panic: file istream.c: line 167 (i_stream_read): assertion failed: (old_size <= _stream->pos - _stream->skip) Error: Raw backtrace: /usr/lib64/dovecot/libdovecot.so.0(+0x6bbef) [0x7f50652a4bef] -> /usr/lib64/dovecot/libdovecot.so.0(+0x6bc4e) [0x7f50652a4c4e] -> /usr/lib64/dovecot/libdovecot.so.0(i_fatal+0) [0x7f506525e2be] -> /usr/lib64/dovecot/libdovecot.so.0(i_stream_read+0x214) [0x7f50652ad904] -> /usr/lib64/dovecot/libdovecot.so.0(i_stream_read_data+0x3d) [0x7f50652adfed] -> /usr/lib64/dovecot/libdovecot.so.0(message_get_body_size+0x9d) [0x7f5065299b3d] -> /usr/lib64/dovecot/libdovecot-storage.so.0(index_mail_init_stream+0x200) [0x7f506556f700] -> /usr/lib64/dovecot/libdovecot-storage.so.0(+0x2dd0f) [0x7f506553cd0f] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mail_get_stream+0x4b) [0x7f506554915b] -> /usr/lib64/dovecot/libdovecot-storage.so.0(+0x2dae7) [0x7f506553cae7] -> dovecot/pop3(client_create+0x56d) [0x40622d] -> dovecot/pop3() [0x404ea3] -> dovecot/pop3() [0x40508f] -> /usr/lib64/dovecot/libdovecot.so.0(+0x28346) [0x7f5065261346] -> /usr/lib64/dovecot/libdovecot.so.0(+0x28841) [0x7f5065261841] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_call_io+0x4e) [0x7f50652b58de] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handler_run_internal+0xd7) [0x7f50652b68b7] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handler_run+0x9) [0x7f50652b5969] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_run+0x38) [0x7f50652b59e8] -> /usr/lib64/dovecot/libdovecot.so.0(master_service_run+0x13) [0x7f50652635a3] -> dovecot/pop3(main+0x233) [0x404bf3] -> /lib64/libc.so.6(__libc_start_main+0xf5) [0x7f5064eb6db5] -> dovecot/pop3() [0x404d49]

About network throughput between Director and backends
by Listas＠Adminlinux 21 Aug '14

21 Aug '14

I plan to migrate my Dovecot IMAP servers to a clustered structure. I'm planning a cluster with high availability and load balancing. I know I need instances of Dovecot Proxy / Director. But these instances can be on another network? There is need for high network throughput between the Director and the backends? For me it would be cheaper to run Director in VM's at Amazon AWS for example. Thanks! -- Thiago Henrique

doveadm proxy list
by Claus 21 Aug '14

21 Aug '14

Hi, i have configured my dovecot-proxy with "shutdown_clients = no" and "service_count = 1" for a "default_process_limit = 5000" and "default_client_limit = 25000". I don't know if this is a prefered setup for so many users/concurrent sessions but so i can reload my dovecot without disconnecting all sessions. The main problem are pop3 sessions - if i kill them, the mailbox remains locked and the client gets an error. Back to my problem: If i reload dovecot the "doveadm proxy list" shows me the list of the new processes. Is there any possibility to see the stats of the old sessions (user,source,destination) ? greet's Claus PS.: Could someone explain me why i have to set default_client_limit to 5x default_process_limit?

rebuilding indexes for dovecot pop3
by Arkadiusz Miśkiewicz 21 Aug '14

21 Aug '14

Hi. doveadm -D fetch -u login \ 'imap.envelope imap.bodystructure size.virtual date.received' '*' according to mail archives allows to regenerate indexes and precache specified headers for imap usage. What headers are needed for dovecot pop3 daemon? I have one server where dovecot works for imap only. For pop3 there is different software being used. I want to migrate to dovecot pop3 but I need to precache and regenerate indexes for dovecot pop3. Note, some users used pop3 only, so dovecot imap had no chance to generate any indexes.

Fatal: lazy_expunge: Unknown namespace: '.EXPUNGED/'
by Philipp Faeustlin 21 Aug '14

21 Aug '14

Hello List, with dovecot version 2.2.13.9, I actually have a problem using lazy_expunge and acl together. Shared/Public Folders work fine with lazy_expunge disabled. If lazy_expunge is enabled and userA got a shared folder form userB, then there is the error shown in subject. My test case to reproduce the error. doveadm mailbox list -u userA@domain --> Output Fine. doveadm acl set -u userB@domain INBOX user=userA@domain lookup read write write-seen write-deleted insert expunge create --> Fine. doveadm mailbox list -u userA@domain --> Some output and then: --> doveadm(userA@domain): Fatal: lazy_expunge: Unknown namespace: '.EXPUNGED/' I think this is a bug in dovecot, can someone of the dovecot developers or someone else confirm this? If it is not please show me the fault in my configuration.

New user mailbox permission
by Gionatan Danti 21 Aug '14

21 Aug '14

Hi all, I have a problem with my Dovecot installation. First, some informations: - OS: CentOS 6.5 x86_64 - Dovecot: dovecot-2.0.9-7.el6.x86_64 Config: mail_location = sdbox:~/dbox user_query = SELECT username, password, 'vmail' as uid, 'vmail' as gid, '/var/vmail/%d/%n' as home, CONCAT('*:storage=', (quota DIV 1000)) as quota_rule FROM mailbox WHERE username='%u' What I want to do is to create a backup user to rsync the mailstore to a remote location. If possible, I don't want to use the root user for this operation. I already added the backup user to "vmail" group. The problem is that when a new user is created, it's base directory permission are 0700 (vmail:vmail). From what I read here (http://wiki2.dovecot.org/SharedMailboxes/Permissions, "Permissions to new /domain/user directories"), simply using the setgid bit is not sufficient because I am not using an absolute path for mail_location. My questions are: 1) all I need to do is to switch to an absolute mail_location? 2) it is possibile to solve my problem _without_ altering mail_location?

How to configure read-only access during a migration?
by Jeffrey Tunison 20 Aug '14

20 Aug '14

Hi. I would appreciate your advice about these TWO PROBLEMS: ======================================================= Find the simplest way to A) configure a Dovecot 2.2.10 IMAP server to access (existing) email users' (mbox-format) mail folders ****in read-only mode.**** B) Do the above while allowing a master_user to access mail on behalf of real users. (I've got master_user access working in read-write mode.) Simplest because while I'm proficient at UNIX systems administration, I'm under time pressure and dovecot has a lot of configuration flexibility. Identifying the right way to do this is proving time- consuming. Namespaces? ACL's? passdb's? I thought it was time to bring in the dovecot wizards. You! GOAL: ======================================================= Without knowing or changing users' passwords, migrate several hundred users of dovecot IMAP to MS Exchange using the commercial product Transend. I'm manging the dovecot side, someone else is doing the Transend/Exchange piece. Migration would occur in batches due to slowness of the Transend side when dealing with users with email collections over a few gigabytes. I have a production IMAP server (dovecot 1.0.13 on 32-bit RHEL 4.9). Let's call it PROD for short. Users INBOXes are stored locally on PROD. Their other mail folders are stored on a second machine and accessed via NFS. Those other folders contain the great majority of the email to be migrated. Let's call the NFS server MIGR for short. On MIGR, I've set up a migration IMAP server (dovecot 2.2.10 on 64-bit RHEL 5.10). MIGR is a dedicated NFS server with newer hardware than PROD. It has an unused Ethernet NIC I can tell Transend to use. Both PROD and MIGR use NIS for authentication. Therefore PAM is consulted for passdb information, normally. No SQL db's used. I set up the second server (MIGR) for several reasons: 1) there are some users mail folders larger than the 32-bit file size limit found on the PROD server. 2) the bulk of the email is stored locally on the MIGR server. 3) the version of dovecot is much newer and therefore more likely to have fewer bugs and more configuration options. 4) I don't want to modify the production environment except where really necessary. Pointing Transend at MIGR instead of PROD seems like it will be faster and better. Telling end-users to use MIGR instead of PROD would allow them to verify that their email came across okay (into MS Exchange) without being able to modify the original copy of email (in Dovecot). In the days and weeks after migration. I may need to re-enable write access on PROD for certain users if the migration does not succeed. Transend has been dying on a number of test users despite tweaking its parameters in consultation with the vendor. "Corrupt" messages seem to be the issue. Users (or sysadmins) might be required to identify and delete the offending messages before we retry their migration. (Which folders and which messages are causing problems will hopefully be discernible in Transend logs.) Ha! If you've read this far, then I'd also say that I welcome any advice on changes to increase performance on MIGR, such as whether trying to minimize indexing as I've done is useful. Current configurations of the two servers follow. =========================================================================== PRODUCTION: =========================================================================== # 1.0.13: /etc/dovecot.conf log_path: /var/log/dovecot.log info_log_path: /var/log/dovecot.log protocols: imaps imap listen: *:143 ssl_listen: *:993 ssl_cert_file: /etc/pki/dovecot/certs/dovecot.pem ssl_key_file: /etc/pki/dovecot/private/dovecot.key login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login login_processes_count: 20 login_max_processes_count: 500 max_mail_processes: 1524 first_valid_uid: 100 mail_location: mbox:~/Mail:INBOX=/var/mail/%u:INDEX=/var/spool/dovecot-indexes/%u/ mbox_read_locks: dotlock mbox_write_locks: dotlock mbox_dotlock_change_timeout: 60 mbox_min_index_size: 2048 namespace: type: private separator: / inbox: yes namespace: type: private separator: / prefix: Mail/ hidden: yes namespace: type: private separator: / prefix: ~/Mail/ hidden: yes namespace: type: private separator: / prefix: mail/ hidden: yes namespace: type: private separator: / prefix: ~/mail/ hidden: yes auth default: master_user_separator: * verbose: yes debug: yes debug_passwords: yes passdb: driver: passwd-file args: /etc/dovecot.transend master: yes passdb: driver: shadow passdb: driver: pam userdb: driver: passwd =========================================================================== MIGRATION: =========================================================================== # 2.2.10: /etc/dovecot/dovecot.conf # OS: Linux 2.6.18-348.18.1.el5 x86_64 Scientific Linux release 5.10 (Boron) auth_debug = yes auth_debug_passwords = yes auth_master_user_separator = * auth_verbose = yes auth_verbose_passwords = plain first_valid_uid = 100 log_path = /var/log/dovecot.log mail_debug = yes mail_location = mbox:~/Mail:INBOX=/var/spool/concmail/%u:INDEX=MEMORY mbox_min_index_size = 50048 B mbox_write_locks = fcntl namespace four { hidden = yes location = prefix = ~/mail/ separator = / } 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 = } namespace one { hidden = yes location = prefix = Mail/ separator = / } namespace three { hidden = yes location = prefix = mail/ separator = / } namespace two { hidden = yes location = prefix = ~/Mail/ separator = / } passdb { args = /etc/dovecot/dovecot.transend driver = passwd-file master = yes } passdb { driver = pam } protocols = imap service imap-login { process_min_avail = 15 service_count = 10 } service imap { process_limit = 2048 } ssl = required ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { driver = passwd } verbose_proctitle = yes protocol imap { mail_max_userip_connections = 1000 }

LMTP re-reading all messages
by Florent Bautista 20 Aug '14

20 Aug '14

Hi all, I have a little problem with Dovecot 2.1.17 and MailDir accounts. I was using a shared file system (MooseFS), and all was pretty stable. Now I'm switching to CephFS, and Dovecot LMTP have problem to deliver mails. Very often, on large accounts, LMTP processes are running for a few hours before delivering the message. When I strace it, I can see that they are reading (open and stat operations) ALL the messages of the account. I was thinking to an index problem, but I think that after hundreds of delivered mails, indexes are rebuilded and problem should be solved. But not. The same way, If user connects to IMAP, a lot of IMAP processes get stuck on "getquotaroot" command (multiple processes for a single account). The previous FS didn't support mmap, so I disabled it. The new one supports it, so I enabled it, but it does not solve the problem. Do you have an idea of why Dovecot (LMTP or IMAP) spend a lot of time on large accounts ? Thank you a lot. Florent

antispam plugin crash
by Thomas Witt 20 Aug '14

Hi, the dovecot antispam plugin crahses here on a nullpointer dereference in antispam_copy() at mailbox.c The crash tracks back to a call of antispam_classify_copy(asms->box_class, asmb->box_class) At that point in time asmb is set to 0x0, causing the process to crash with SIGSEGV. Regards, Thomas GDB output: Program received signal SIGSEGV, Segmentation fault. antispam_copy (ctx=0x14ed9f0, mail=0x14c6cc0) at mailbox.c:107 107 enum mailbox_copy_type copy_type = (gdb) bt #0 antispam_copy (ctx=0x14ed9f0, mail=0x14c6cc0) at mailbox.c:107 #1 0x00007fdadb627fcd in mailbox_copy () from /usr/lib64/dovecot/libdovecot-storage.so.0 #2 0x00007fdada6cdba0 in act_store_execute () from /usr/lib64/dovecot/libdovecot-sieve.so.0 #3 0x00007fdada6c59d9 in sieve_result_execute () from /usr/lib64/dovecot/libdovecot-sieve.so.0 #4 0x00007fdada6d4a2a in sieve_execute () from /usr/lib64/dovecot/libdovecot-sieve.so.0 #5 0x00007fdada9212cb in lda_sieve_deliver_mail () from /usr/lib64/dovecot/lib90_sieve_plugin.so #6 0x00007fdadb8cae1a in mail_deliver () from /usr/lib64/dovecot/libdovecot-lda.so.0 #7 0x0000000000405ebd in client_input_data_handle () #8 0x00007fdadb34e9bf in io_loop_call_io () from /usr/lib64/dovecot/libdovecot.so.0 #9 0x00007fdadb34f8b7 in io_loop_handler_run_internal () from /usr/lib64/dovecot/libdovecot.so.0 #10 0x00007fdadb34ea29 in io_loop_handler_run () from /usr/lib64/dovecot/libdovecot.so.0 #11 0x00007fdadb34eaa8 in io_loop_run () from /usr/lib64/dovecot/libdovecot.so.0 #12 0x00007fdadb2fe803 in master_service_run () from /usr/lib64/dovecot/libdovecot.so.0 #13 0x0000000000404995 in main () (gdb) p asms $3 = (struct antispam_mailbox *) 0x0

Dovecot v2.2 FTS is not indexing "text/html" emails...
by Akash 20 Aug '14

20 Aug '14

Hi, I am not sure its intended or a fault in the newest Dovecot versions. I have been using Dovecot v1.2.15 on Debian squeeze and FTS is working as expected. When I search a quoted string "very good", I get 107 results including plain and HTML emails which have this phrase. In order to compare the benefits of lucene over squat, I recently started testing dovecot v2.2.13 on Debian Sid with the same maildir content. But now the same search "very good" yielded just 8 results. I thought it could be some problem with lucene so I tried switching to squat and got 107 results again. After this I deleted the old squat search index files created by v1.2.15 and re-indexed the mail-box by using doveadm index command. Now the same squat search is giving 8 results just as lucene. So I have realized that its not a problem with just lucene but FTS in newer dovecot isn't indexing those emails which have Content-type as text/html. Thus if a mail is like this: Content-Type: text/html <b>He is very good.</b> It isn't shown in search by the squat indexes created using dovecot v2.2.13. I have done further testing on some sample emails which confirmed this behavior. Why is this so? -Regards, Akash

auth_username_translation and LTMP problem
by Arkadiusz Miśkiewicz 20 Aug '14

20 Aug '14

auth_username_translation seems to be appliet on RCPT TO address of LTMP transport. Why dovecot is doing that? And better question - is there a way to disable auth_username_translation for LTMP but leave enabled for the rest (imap, pop3 etc) ? Background: I'm doing auth_username_translation = @= to allow logins like aaa(a)bbb.pl to be internally translated to aaa=bbb.pl. That works fine. Now my exim delivers mail to dovecot using LTMP and it does translation or it own, so it does: RCPT TO: <aaa=bbb.pl(a)mymbox.pl> Unfortunately looks like dovecot it doing translation one more time and looking in user database for aaa=bbb.pl=mymbox.pl where such user doesn't exist. Only aaa=bbb.pl user exists. Thanks, -- Arkadiusz Miśkiewicz, arekm / maven.pl

Mail Archiving/Lucene Indexes/mbox
by Larry Rosenman 20 Aug '14

20 Aug '14

I have a script (available on demand) that moves all my mail for a given month to a separate NAMESPACE (#ARCHIVE). When I do that, the lucene-indexes folder in the PRIMARY namespace seems to get cleaned out, and NOTHING gets put in the lucene-indexes folder (although it gets created) in the #ARCHIVE namespace. Is this to spec? the archiving is done via doveadm move commands.

Segfault with indexer-worker using Tika/Solr
by G H 20 Aug '14

20 Aug '14

Using Dovecot 2.2.13 with Tika 1.5 on Centos 5 64bit Tika is throwing an exception for some reason, which seems to be causing Dovecot's indexer to segfault. I'm using mdbox/gzipped compressed mail and private indexes for the shared folder. I'm importing mail via formail/dovecot-lda: formail -s /usr/libexec/dovecot/dovecot-lda -d admin -m Public/TestSubFolder < /tmp/Inbox.mbox dovecot -n and the GDB backtrace are attached. # find /var/mail/ -maxdepth 2 /var/mail/_public /var/mail/_public/dovecot.mailbox.log /var/mail/_public/dovecot-uidvalidity /var/mail/_public/dovecot-uidvalidity.53ecade1 /var/mail/_public/storage /var/mail/_public/subscriptions /var/mail/_public/mailboxes /var/mail/admin /var/mail/admin/dovecot-uidvalidity.53ecade2 /var/mail/admin/dovecot.mailbox.log /var/mail/admin/public /var/mail/admin/dovecot-uidvalidity /var/mail/admin/storage /var/mail/admin/subscriptions /var/mail/admin/mailboxes

BUG: Solr FTS engine appends domain name to index records
by G H 20 Aug '14

20 Aug '14

The Solr FTS engine appends domain names to the "user" and "id" fields inside Solr when indexing. However, when an IMAP search is performed, the domain name is not appended, resulting in 0 results, 100% of the time. You can reproduce this by setting up dovecot to have user names like "admin", "james", etc (as opposed to admin(a)example.com) Then import some mail (ie: "dovecot-lda -d admin < /tmp/mymail.txt"). Now attempt to search for that mail and it will not be returned as a result. You can see in the Solr GUI (http://xxxx:8983/solr/) that record is indexed as: { "uid": 1, "box": "7dff0b0d4f84df53f25300003d823887", "user": "admin(a)example.com", "id": "1/7dff0b0d4f84df53f25300003d823887/admin(a)example.com", "_version_": 1475511406809841700 } However, the IMAP search is sent to Solr performed with user:"admin" instead of user:"admin(a)example.com". Either the Solr FTS plugin needs to not append the domain name or the search does need to do so.

Trouble getting public folders working
by Bjarne Mark Kondrup 20 Aug '14

Hi i have trouble getting my public folders working properly. I have a few issues atm with them. First off i'm using version 2.0.9 as it came with CentOS and would greatly prefer to keep this version. Here is my dovecot.conf file # dovecot -n # 2.0.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-431.23.3.el6.centos.plus.x86_64 x86_64 CentOS release 6.5 (Final) ext4 auth_debug = yes auth_verbose = yes disable_plaintext_auth = no first_valid_uid = 101 last_valid_uid = 101 login_greeting = Dovecot ready.

I cannot get shared folders to work with pr. user settings. What i want is a public folder that all my users can see but each user marks mail as read individually. Atm no matter how i set it up if user1 marks a mail as read, then user2 will also see that mail as read :( 2. ACL to control the permissions. Right now all users can move mail and remove mail from the shared folders. I want people (except a few specific users) to be read only on this public folders. 3. Need to know if i'm creating the folders correctly. Right now i'm under my shared folder directory creating shared_folder and 3 subfolders beneath it (cur, new and tmp). After this it shows up in eg. roundcube and i can subscribe to it. I have read all the documentation and tried all the solutions i can. Mostly moving the index and/or config files to seperate dirs and from my understanding that should give each user their own index file marking what mails have been read ect. But this doesn't happen. Hope you guys are able to help me out a little here. -Bjarne

Huge difference between the lucene index size created by v2.1 and v2.2
by Akash 20 Aug '14

20 Aug '14

Hi everyone, While examining dovecot versions v2.1 and v2.2 for their lucene search performances, I have noticed a huge difference in the index sizes created by them. Both versions were compiled on same system, against same libclucene, same configure options and were used with same dovecot.conf during run-time. I deleted the lucene-indexes folder and dovecot* files in the Maildir prior to indexing with both versions. The tests were performed on a untouched mail archive folder containing 300000 mails without any dovecot* files in it: root@server:/home/admin/mails/.Archive# ls -l total 78640 drwx------ 2 2500 2500 14098432 Aug 17 22:16 cur drwx------ 2 2500 2500 12435456 Jul 30 09:46 new drwx------ 2 2500 2500 4096 Aug 2 13:02 tmp The command used was: doveadm -v index -u admin Archive After search indexing on v2.1 resulted in: root@server:/home/admin/mails# ls -lh lucene-indexes total 390M -rw------- 1 2500 2500 390M Aug 18 07:03 _25.cfs -rw------- 1 2500 2500 20 Aug 18 07:03 segments.gen -rw------- 1 2500 2500 46 Aug 18 07:03 segments_4d Whereas dovecot v2.2 resulted in: root@server:/home/admin/mails# ls -lh lucene-indexes total 1.5G -rw------- 1 2500 2500 1.5G Aug 18 06:41 _5g.cfs -rw------- 1 2500 2500 20 Aug 18 06:41 segments.gen -rw------- 1 2500 2500 46 Aug 18 06:41 segments_az 390M vs 1.5G. That is a huge difference in size. Why is that? Thanks in advance. -Regards, Akash

Problems with dovecot 2.2.13 and monit
by Hanno Böck 20 Aug '14

20 Aug '14

Hello, When I upgraded my servers to dovecot 2.2.13 the monitoring tool monit started to send out warnings that it couldn't reach my imap/pop3 servers through ssl any more. The same problem didn't happen on non-ssl-connections. According to people on the monit list this is likely a dovecot issue: https://lists.gnu.org/archive/html/monit-general/2014-06/msg00031.html Let me quote: > the root cause of the error is, that dovecot 2.2.13 closes the > connection if SSL is used in response to LOGOUT command instead of > sending usual response. When no SSL is enabled, dovecot responses to > LOGOUT command normally. [...] > According to RFC 3501 (http://tools.ietf.org/html/rfc3501) LOGOUT is > any-state command, where the server MUST send response before closing > the connection: http://tools.ietf.org/html/rfc3501#section-3.4 > > => the problem is caused by dovecot 2.2.13 bug ... its behaviour is > inconsistent (LOGOUT in non-authenticated state works per RFC > requirement if no SSL is used and doesn't conform to RFC if SSL is > used). It is possible that the problem is related to their DoS-attack > modification, which has most probably unexpected side-effect. Maybe this is related to the DDoS-protection measures that have been added in dovecot 2.2.13. Would apprechiate if someone could have a look. cu, -- Hanno Böck http://hboeck.de/ mail/jabber: hanno(a)hboeck.de GPG: BBB51E42

Does Dovecot Director health monitoring of backend servers ? Or is poolmon (http://www.dovecot.org/list/dovecot/2010-August/051946.html) the best option for this? Maybe Ldirectord? Thanks! -- Thiago Henrique www.adminlinux.com.br

IMAP on 993/SSL or 143/STARTTLS?
by Alex 18 Aug '14

18 Aug '14

Hi, I have a postfix+dovecot-2.2.13 system and have configured it to support IMAPS on 993 with SSL/TLS. I'm noticing with users using Thunderbird, the autodetect defaults to IMAPS on 143 with STARTTLS. Which is preferred? Which is more secure? Which is more common? Why would someone choose one over the other? Can I ask the same question about SMTP and submission? Why would one choose 587 with STARTTLS versus 465 with SSL/TLS? Thanks, Alex

Dovecot failing with exit code 19200 in cron job
by Murray Trainer 18 Aug '14

18 Aug '14

Hi All, I am synchronizing a few hundred dovecot mailboxes with a perl script via a crontab. It works for a while (ie exit status=0) but the rest then start failing with exit code 19200. I tried redirecting STDERR but showed nothing. I suspect the cron job is hitting some sort of resource limit? If I run the perl script from the command line it appears to dsync all the accounts OK. The relevant part of my Perl code is below. Any ideas? Thanks, Murray foreach (@userlist) { my $email = $_; chomp ($email); # get rid of CR logit("Started sync of mailbox $email") if $debug; my $dsync_command="dsync -v -D -u $email mirror ssh -C root@$mailstore dsync -u $email"; logit("dsync_command=$dsync_command"); # Run dsync of mailbox logit("Started secondary sync of $mailbox to $mailstore") if $debug; my $exit_status = system ( $dsync_command ); logit("Dsync exit status: $exit_status") if $debug; logit("Finished secondary sync of $mailbox to $mailstore") if $debug; }

NFS INTR mount option
by Murray Trainer 18 Aug '14

Hi again, We have our mailboxes on several NFS filesystems mounted with the options below. 10.11.0.238:/mailbox_store_01 on /home1 type nfs4 (rw,noatime,vers=4.0,rsize=65536,wsize=65536,namlen=255,hard,nordirplus,proto=tcp,port=0,timeo=600,retrans=2,sec=sys,clientaddr=10.11.0.95,local_lock=none,addr=10.110.238) On the rare occasions that the NFS mounts hang, the system load goes through the roof and I often have to reboot the mailstore server as dovecot process are hung and can't be killed. Will the NFS INTR mount option help in this situation? Thanks Murray Send EMAIL [1] Links: ------ [1] https://webmail.westnet.com.au/index.php/mail#

INBOX subfolders not showing up
by Matthias Sitte 16 Aug '14

16 Aug '14

Hi, I have a problem with INBOX subfolders and subscriptions which I can't solve... Maybe somebody has seen this, too... I can create regular subfolders (not in INBOX) and (un-)subscribe to them with Thunderbird. If I create subfolders in the INBOX with TB this seems to work now in v31 (just found this out), but with v24.6 neither INBOX subfolder creation nor subscriptions worked. When I modified the `subscriptions' file manually on the server, the folders would show up in TB, though. Maybe this was a TB bug, but quite similarly INBOX subfolders don't show up on iPhones (iOS up-to-date), but all other subfolders do. Any ideas what's going on?

Hello, I am having an issue with Dovecot. I am using Roundcube to access my mailboxes, which I have set up using ViMbAdmin. However when I go to the Roundcube, I get login Failed. So looking in the mail.log I can see the following: Aug 15 13:20:09 Server dovecot: auth: Warning: sql: Ignoring changed iterate_query in /etc/dovecot/dovecot-sql.conf.ext, because userdb sql not used.

namspace management
by A. Schulze 15 Aug '14

15 Aug '14

Hello, since some weeks I'm playing with namespaces. But I still did nod found a solution for all faces of different problems. Current issue: Public namespace. I have users inbox as follow: mail_home = /data/mail/%Ln/ mail_location = maildir:~/Maildir:INDEX=~/.dovecot.index namespace { inbox = yes separator = / prefix = INBOX/ } Public namespace: namespace { location = maildir:/data/mail_public/Maildir/:INDEXPVT=~/.dovecot.index.public/ prefix = PUBLIC/ separator = / type = public } that way only one subscription file is possible. Any use could subscribe/unsubscribe any folder and that match all users. If I add "subscription=no" the parent namespace' subscription is used. In fact there is no parent namespace an no subscription management is possible at all. On the other side I tried to change the PUBLIC namespace prefix to "INBOX/PUBLIC" but now the namespace is *below* the inbox. That's also not what I want. How do other users organise the namespaces INBOX, PUBLIC, SHARED and VIRTUAL (via virtual plugin) ? Thanks Andreas

The parentheses in the subject are due to referral to this discussion on the mailing list: http://dovecot.org/list/dovecot/2012-February/063851.html At first I thought I found the problem, but then realized this was 2012 and the suggested patch already is applied in dovecot.

The used CMS is PyroCMS (v2.2.3) - the version is not up2date, but nevertheless the CMS might be the one to blame, a service should not segfault. Some packages are to be updated, as well as the CMS; but I am willing to wait to provide information, which leads to the problem, as I cannot switch between different versions on my productive system for the sake of gaining debug information. I hope that someone has any kind of clue and is willing to resolve that issue with me, asking me for the necessary information to do so. Thanks in advance!

Multiple Passdb's - Order
by Jean-Louis Dupond 15 Aug '14

15 Aug '14

Hi, Today I upgraded my dovecot to a newer version (2.2.9 debian wheezy-backports) At that moment I also reconfigured the whole thing a bit nicer. Now I stumbled on the following issue. In my configuration I use 2 backends (LDAP & passwd-file). passdb { args = scheme=CRYPT username_format=%u /etc/dovecot/users driver = passwd-file } passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } userdb { args = uid=vmail gid=vmail home=/var/vmail/%d/%n driver = static } Now this worked fine before. But if I tested it, LDAP logins worked, and passwd-file logins failed. Failed log (user is only in the passwd-file): Aug 01 21:31:55 auth: Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth Aug 01 21:31:55 auth: Debug: Module loaded: /usr/lib/dovecot/modules/auth/libdriver_mysql.so Aug 01 21:31:55 auth: Debug: Module loaded: /usr/lib/dovecot/modules/auth/libdriver_pgsql.so Aug 01 21:31:55 auth: Debug: Module loaded: /usr/lib/dovecot/modules/auth/libdriver_sqlite.so Aug 01 21:31:55 auth: Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth Aug 01 21:31:55 auth: Debug: Module loaded: /usr/lib/dovecot/modules/auth/libauthdb_ldap.so Aug 01 21:31:55 auth: Debug: Read auth token secret from /var/run/dovecot/auth-token-secret.dat Aug 01 21:31:55 auth: Debug: passwd-file /etc/dovecot/users: Read 10 users in 0 secs Aug 01 21:31:55 auth: Debug: auth client connected (pid=5516) Aug 01 21:31:55 auth: Debug: client in: AUTH 1 PLAIN service=imap secured session=c34kcZb/uwBbtKLu lip=xxx rip=xxxx lport=993 rport=52411 Aug 01 21:31:55 auth: Debug: client passdb out: CONT 1 Aug 01 21:31:55 auth: Debug: client in: CONT 1 xxxxx (previous base64 data may contain sensitive data) Aug 01 21:31:55 auth: Debug: cache(info(a)xxx.com,xxx,<c34kcZb/uwBbtKLu>): miss Aug 01 21:31:55 auth: Debug: ldap(info(a)xxx.com,xxx,<c34kcZb/uwBbtKLu>): pass search: base=uid=info(a)xxx.com,ou=mail,dc=dupie,dc=be scope=subtree filter=(&(objectClass=posixAccount)(uid=info(a)xxx.com)) fields=uid,userPassword Aug 01 21:31:55 auth: Debug: cache(info(a)xxx.com,xxx,<c34kcZb/uwBbtKLu>): miss Aug 01 21:31:55 auth: Debug: cache(info(a)xxx.com,xxx,<c34kcZb/uwBbtKLu>): miss Aug 01 21:31:55 auth: Debug: passwd-file(info(a)xxx.com,xxx,<c34kcZb/uwBbtKLu>): lookup: user=info(a)xxx.com file=/etc/dovecot/users Aug 01 21:31:57 auth: Debug: client passdb out: FAIL 1 user=info(a)xxx.com temp Aug 01 21:31:57 auth: Debug: client in: AUTH 2 PLAIN service=imap secured session=c34kcZb/uwBbtKLu lip=xxx rip=xxx lport=993 rport=52411 resp=xxx (previous base64 data may contain sensitive data) Aug 01 21:32:01 auth: Debug: cache(info(a)xxx.com,xxx,<c34kcZb/uwBbtKLu>): miss Aug 01 21:32:01 auth: Debug: ldap(info(a)xxx.com,xxx,<c34kcZb/uwBbtKLu>): pass search: base=uid=info(a)xxx.com,ou=mail,dc=dupie,dc=be scope=subtree filter=(&(objectClass=posixAccount)(uid=info(a)xxx.com)) fields=uid,userPassword Aug 01 21:32:01 auth: Debug: cache(info(a)xxx.com,xxx,<c34kcZb/uwBbtKLu>): miss Aug 01 21:32:01 auth: Debug: cache(info(a)xxx.com,xxx,<c34kcZb/uwBbtKLu>): hit: {CRAM-MD5}19192922.....

Cannot use dovecot with vpopmail and sendmail
by Matthias Fechner 15 Aug '14

15 Aug '14

Hi, I setup a configuration that will use sendmail with dovecot as imap/pop3 service and vpopmail as backend to handle virtual users and store email there. For this I created a dovecot.m4 as described in the wiki, it looks like: ######################*****############## ### DOVECOT Mailer specification ### ##################*****################## Mdovecot, P=/usr/local/libexec/dovecot/dovecot-lda, F=l59DFMPhnu, S=EnvFromSMTP/HdrFromSMTP, R=EnvToSMTP/HdrFromSMTP, M=51200000, U=vpopmail:vchkpw, T=DNS/RFC822/X-Unix, A=/usr/local/libexec/dovecot/dovecot-lda -d $u Then I added to my .mc file: MAILER(dovecot) I added to my mailertable: dovecot.fechner.net dovecot:dovecot I create one entry in the virtusertable to catch a email and forward it to dovecot (all other email have to handled by another imap server till dovecot is running fine): dovecot(a)fechner.net idefix(a)dovecot.fechner.net I created a domain and a user in vpopmail to catch idefix(a)dovecot.fechner.net. If I execute: doveadm auth test idefix(a)dovecot.fechner.net Password: passdb: idefix(a)dovecot.fechner.net auth succeeded extra fields: user=idefix(a)dovecot.fechner.net So I think the first part is fine.

Trying Dovecot Replication with dsync
by Minhas Listas 14 Aug '14

14 Aug '14

Hi, I have a failover cluster for mail server with: Ubuntu12.04 + DRBD (for block replication) + Ext4 filesystem + Dovecot-2.0.19-2 with Mdbox It works fine with ~50k accounts. My cluster design: http://adminlinux.com.br/cluster_design.txt I plan to test Dovecot Replication with dsync to build an active/active cluster with load balancing. Can anyone direct me to some literature? A tutorial for example. I'm installing a cluster (for tests) with Ubuntu 14.04 + Ext4 filesystem (without Drbd) + Dovecot-2.2.9-1ubuntu2.1. My conf is in: http://adminlinux.com.br/replication-doveconf.txt I'm following this doc http://wiki2.dovecot.org/Replication but I'm getting some errors: 1) Aug 14 15:39:34 ceph1 dovecot: imap(account=domaintest.com): Error: open(/var/run/dovecot/replication-notify-fifo) failed: Permission denied What is the correct perms for /var/run/dovecot/replication-notify-fifo ?

Quota Help
by user7743 14 Aug '14

14 Aug '14

Hi all, First post here so hopefully I get all the required information correct. I am running a mail server on Debian, its consists of Postfix (2.9.6-2), Dovecot (2.1.7) and MySQL (5.5). Basic stuff is all working find so I decided to try and implement quotas. This is working to an extent but not properly and I am a little lost so looking for some help. In my configuration the default mailbox quota is set to "*:storage=100M". When I create a mailbox with 250M specified in the database, dovecot is applying the default quota rather than that specified in the database. So in the database I have a test user with the following entry password,email,quota_kb [hash], test(a)example.org, 25000 If I turn debugging on for mail and auth I see the following logged when the user logs in (logs pasted at the end in a bid to maintain some readability) If I check the quota with doveadm I get the limit back of 102400 which is the default mailbox size rather than that from the database. doveadm quota get -u test(a)example.org Quota, name, Type, Value, Limit, % User quota, STORAGE, 19139, 102400, 18 User quota, MESSAGE, 567, - I can't quite figure out where I am going wrong in terms of getting the database value to supersede the default value set in 90-quota.conf. I did read one thing in the quota documentation on the dovecot website (http://wiki2.dovecot.org/Quota/Configuration) that I didn't get and this might be where I am going wrong but can't check. It says "Check that dovecot-lda is called with -d parameter." Where would this be configured and where could I check? Below are some other inputs - hopefully they help. ### Debug logs at login Aug 14 14:06:24: auth: Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth Aug 14 14:06:24: auth: Debug: Module loaded: /usr/lib/dovecot/modules/auth/libdriver_mysql.so Aug 14 14:06:24: auth: Debug: auth client connected (pid=8090) Aug 14 14:06:24: auth: Debug: auth client connected (pid=8093) Aug 14 14:06:24: auth: Debug: client in: AUTH#0111#011PLAIN#011service=imap#011secured#011session=2QDLu5UAKAAuBSdf#011lip=99.99.99.99#011rip=55.55.55.55#011lport=993#011rport=50216 Aug 14 14:06:24: auth: Debug: client out: CONT#0111#011 Aug 14 14:06:24: auth: Debug: client in: AUTH#0111#011PLAIN#011service=imap#011secured#011session=ZBnLu5UAKQAuBSdf#011lip=99.99.99.99#011rip=55.55.55.55#011lport=993#011rport=50217 Aug 14 14:06:24: auth: Debug: client out: CONT#0111#011 Aug 14 14:06:24: auth: Debug: client in: CONT<hidden> Aug 14 14:06:24: auth-worker(8095): Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth Aug 14 14:06:24: auth-worker(8095): Debug: Module loaded: /usr/lib/dovecot/modules/auth/libdriver_mysql.so Aug 14 14:06:24: auth-worker(8095): mysql(127.0.0.1): Connected to database mailserver Aug 14 14:06:24: auth-worker(8095): Debug: sql(test.example.org,55.55.55.55): query: SELECT email as user, password FROM users WHERE email='test.example.org';

Domain name lost for SASL
by Dominic Wong 13 Aug '14

13 Aug '14

Hi, I'm trying to set up Postfix + Dovecot (2.0.9) + PostfixAdmin on CentoOS (the standard amazon machine image) and am having problems with my SMTP user authentication. Turning on auth debugging I can see the username is losing the first part of the domain so one(a)two.three becomes one.three dovecot: auth: Debug: sql(one.three, ... ): query: SELECT username AS user,password FROM mailbox WHERE username = 'one.three' AND active='1' I don't know if it's postfix or dovecot which is trimming the username, any tips on what causes this would be greatly appreciated. Thanks

Defer email via LMTP when there is 'no space left on device' instead of rejecting it
by Christian Rohmann 12 Aug '14

12 Aug '14

Hello dovecot-users, (This problem was being discussed a little in this thread from 2011: http://www.dovecot.org/list/dovecot/2011-May/059009.html) I noticed (using LMTP) that Dovecot handles 'no space left on device' just like an 'over-quota', if I read this part of method "static int client_deliver(struct client *client, const struct mail_recipient *rcpt, struct mail *src_mail, struct mail_deliver_session *session)" "lmtp/commands.c" correctly: --- cut --- [...] else if (storage != NULL) { error = mail_storage_get_last_error(storage, &mail_error); if (mail_error == MAIL_ERROR_NOSPACE) { client_send_line(client, "%s <%s> %s", dctx.set->quota_full_tempfail ? "452 4.2.2" : "552 5.2.2", rcpt->address, error); } else { client_send_line(client, "451 4.2.0 <%s> %s", rcpt->address, error); } ret = -1; [...] --- /cut --- In consequence this means the configuration option quota_full_tempfail is applied in both cases. But to me there is a major difference between a full disk (a.k.a "admin fucked up") and over-quota (a.k.a. "user has simply too much stuff in his mailbox"). So I would like to be able tell Dovecot to reject messages due to full mailboxes, but simply defer those that cannot be stored due to a full disk (which I am to blame for). To me this should result in two separate configuration options for the two problem root-causes: quota_full_tempfail storage_full_tempfail Or did I simply miss or completely misunderstood anything here? Regards Christian

Frequent error: unknown namespace Trash

Hello to all of you! ;-) My first post on this list. I frequently get this error in dovecot.log every time a user logs in and out: ============================= imap(mailaddress): Error: quota: Unknown namespace: Trash ============================= When I change my conf.d/90-quota.conf from "Trash" to ".Trash" (as this is the imap/maildir folder name, the error stays the same, but with the ".Trash" in dovecot.log This is what my 90-quoato.conf looks like: ============================= plugin { quota_rule = *:storage=2G quota_rule2 = Trash:storage=+100M quota_grace = 10%% } ============================= Where can I start my search, what is going wrong?

Sieve: Saving "pristine" messages for backups and spam training
by Jeff Rice 12 Aug '14

12 Aug '14

Hello, I'm trying to work out a way to have my Sieve filter save a "pristine" version of email messages as a backup, primarily to use for training the spam filter. I would like is to have every message saved into a single, site-wide directory (in the global sieve) before being processed additionally and delivered. The messages in that directory will be used to train the spam filter without having to worry about removing Spamassassin headers and so forth. I thought fileinto :copy might do what I wanted, but this creates a backup directory individually for each user. That's unmanageable for the spam training process I use. redirect *could* work, but that adds a header during the process so the email saved would not be "pristine". I'm thinking of using the extprograms plugin to pipe to a program that will do a simple copy. That feels very hackish, however, and I'm hoping there is a more elegant solution. Am I missing something obvious here? Thanks! Jeff

This seems weird, as I would expect it to be more or less randomly distributed over that interval. Does this happen at the top of each minute? If what you observe is true, the only situation I can think of that would cause this is a bunch of POP3 fetch clients running as a cron job synchronized to a minute grid (i.e seconds=0).

Options mail_nfs_storage and mail_nfs_index not in 2.2(.13) example config anymore?
by Christian Rohmann 11 Aug '14

11 Aug '14

Hey dovecot-users, did I miss anything anywhere about the configuration variables "nfs_storage" and "mail_nfs_index" being removed from the example configuration in 2.2? In 2.1 they where both in 10-mail.conf commented out and set to their default "no". But with 2.2 they are not in any of the exmaple config files anymore. doveadm is still showing the variables and they can be used as ever still. Just wondering if I missed something and this should be configured differently on 2.2 now. Regards Christian

poolmon improvements
by Timo Sirainen 11 Aug '14

11 Aug '14

I've been planning to improve poolmon failure checking for a long time already, but I still haven't managed to get to it. Maybe somebody else has more time, so here's a feature request for anyone to implement: poolmon currently gives up immediately if the first check to any service fails. It really should be trying multiple times over multiple seconds before giving up. I think ideally it would be: - Individual check timeout could still be the default 5 seconds - Add full check time setting, which could be e.g. 15 seconds. If all checks fail during this time then disable the host. - If request fails because connection gets rejected, retry quickly, e.g. after 0,1 seconds - If check fails because of protocol errors, wait for a long time, e.g. 1 second So this would avoid backend being removed in situations where it really shouldn't be removed: - Dovecot restarts - Dovecot reloads - load spikes and other random issues that cause temporary problems Especially the load spike is an annoying issue which my plan doesn't even fully solve. The solution to fix a heavily overloaded cluster isn't really to start removing all of its backends that are busy working..

I frequently get this error in dovecot.log every time a user logs in and out: ============================= imap(mailaddress): Error: quota: Unknown namespace: Trash ============================= When I change my conf.d/90-quota.conf from "Trash" to ".Trash" (as this is the imap/maildir folder name, the error stays the same, but with the ".Trash" in dovecot.log This is what my 90-quoato.conf looks like: ============================= plugin { quota_rule = *:storage=2G quota_rule2 = Trash:storage=+100M quota_grace = 10%% } ============================= Where can I start my search, what is going wrong? Just for letting you know: This mailserver is a fresh and clean setup. I am using postfix/dovecotvimbadmin/mysql/spamassassin/clamsmtp. Cheers, Michael

Dovecot v2.2 FTS is not indexing "text/html" emails...
by Akash 09 Aug '14

09 Aug '14

Hi, I am not sure its intended or a fault in the newest Dovecot versions. I have been using Dovecot v1.2.15 on Debian squeeze and FTS is working as expected. When I search a quoted string "very good", I get 107 results including plain and HTML emails which have this phrase. In order to compare the benefits of lucene over squat, I recently started testing dovecot v2.2.13 on Debian Sid with the same maildir content. But now the same search "very good" yielded just 8 results. I thought it could be some problem with lucene so I tried switching to squat and got 107 results again. After this I deleted the old squat search index files created by v1.2.15 and re-indexed the mail-box by using doveadm index command. Now the same squat search is giving 8 results just as lucene. So I have realized that its not a problem with just lucene but FTS in newer dovecot isn't indexing those emails which have Content-type as text/html. Thus if a mail is like this: Content-Type: text/html <b>He is very good.</b> It isn't shown in search by the squat indexes created using dovecot v2.2.13. I have done further testing on some sample emails which confirmed this behavior. Why is this so? -Regards, Akash

Throttling pop3-login connections
by Alex 09 Aug '14

09 Aug '14

Hi, I have a fedora20 system with dovecot-2.2.13 running various services, including pop3. I'm noticing some users are frequently hamming pop3, and wondered if this was normal, or something I should be investigating? Aug 8 14:05:20 email dovecot: pop3-login: Login: user=<user1>, method=PLAIN, rip=97.77.115.121, lip=192.168.1.1, mpid=30509, session=<DnRtDCIAUQBhTXN5> Aug 8 14:05:21 email dovecot: pop3(user1): Disconnected: Logged out top=0/0, retr=0/0, del=0/15, size=5693601 So it is immediately followed by a logout, but when there are 50 of them successively in a five minute period, I wondered if it is creating unnecessary overhead on the system? I suppose this most likely is how they have their email client configured, but wondered if some throttling would be necessary? Any advice would be most appreciated. Thanks, Alex

postfix-dovecot via lmtp
by Timothy Murphy 08 Aug '14

08 Aug '14

I've been trying for some days to get postfix + dovecot + pigeonhole/sieve working on a CentOS-7 home server. I think I may have detected the problem; I read in /var/log/maillog Aug 4 11:29:13 alfred postfix/lmtp[14871]: 9C04C220A99: to=<tim(a)localhost.gayleard.eu>, orig_to=<tim@localhost>, relay=alfred.gayleard.eu[private/dovecot-lmtp], delay=971, delays=971/0.03/0.02/0.1, dsn=4.3.0, status=deferred (host alfred.gayleard.eu[private/dovecot-lmtp] said: 451 4.3.0 <tim(a)localhost.gayleard.eu> Internal error occurred. Refer to server log for more information. (in reply to RCPT TO command)) (I've split one long line here.) 1) I see that the permissions on /var/spool/postfix/private/ are [tim@alfred ~]$ ls -ls /var/spool/postfix/ 4 drwx------. 2 postfix root 4096 Aug 4 11:30 private The socket dovecot-lmtp setup by postfix is in this directory; does dovecot need permission to access this? 2) I see that this mail (a test email from me) was deferred. What exactly does this mean? Where is the mail stored? I couldn't find it anywhere. (It has already been brought to the server by fetchmail.) 3) Am I right in thinking that there are 2 alternatives to dovecot/sieve a) amavisd-new with postfix + spamassassin b) postfix + procmail ? 4) I remember seeing a posting (probably not in this mailing list) describing how one can trace the progress of email through the server. Unfortunately I didn't note the URL, and now cannot find it. Does anyone have a pointer to such a document? As will probably be obvious, I am not at all clear how postfix and dovecot fit together if one introduces lmtp. I take it that without lmtp (or similar) postfix just delivers email to ~/Maildir/cur (in my case), and dovecot is not involved at all until a client (KMail in my case) looks at email? -- Timothy Murphy e-mail: gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin 2, Ireland

Dovecot, Thunderbird and messages in wrong folder
by Gerhard Wiesinger 08 Aug '14

08 Aug '14

Hello, Sometimes it happens that messages (e.g. one or two) appear in wrong folders in Thunderbird (latest version, also past versions, different computers, also Earlybird). When I repair the folder (folder/Settings/Repair Folder) in Thunderbird, the folder is correct then. It happens on my new server with Fedora 20, Dovecot 2.2.13 and Maildir but it also happened on my old server with Fedora 1, Dovecot 2.2.13 and mbox. Has anyone the same issue? Any guess whether it might be a thunderbird or dovecot issue? Anyone has the same issues with thunderbird and a different IMAP server (e.g. cyrus)? Thank you.

invalid/unknown path to storage
by Benjamin Connelly 08 Aug '14

08 Aug '14

Am I correct: pigeonhole now wants the symlink to the filter file to use an absolute path instead of the relative paths we had? i.e.) sieve-filterfile@ -> /home/mail/domain/user(a)domain/roundcube.sieve instead of sieve-filterfile@ -> roundcube.sieve Dovecot logs these: dovecot: managesieve(user(a)domain.org): Warning: sieve-storage: Active sieve script symlink /home/mail/domain.org/user(a)domain.org/sieve-filterfile is broken: invalid/unknown path to storage (points to roundcube.sieve). and the debug log: Jul 29 15:37:59 managesieve(user(a)domain.org): Debug: sieve: Pigeonhole version 0.4.3 initializing Jul 29 15:37:59 managesieve(user(a)domain.org): Debug: sieve: include: sieve_global_dir is not set; it is currently not possible to include `:global' scripts. Jul 29 15:37:59 managesieve(user(a)domain.org): Debug: sieve-storage: using active sieve script path: /home/mail/domain.org/user(a)domain.org/sieve-filterfile Jul 29 15:37:59 managesieve(user(a)domain.org): Debug: sieve-storage: using sieve script storage directory: /home/mail/domain.org/user(a)domain.org/ Jul 29 15:37:59 managesieve(user(a)domain.org): Debug: sieve-storage: using permissions from /home/mail/domain.org/user(a)domain.org/: mode=0700 gid=-1 Jul 29 15:37:59 managesieve(user(a)domain.org): Debug: sieve-storage: relative path to sieve storage in active link: I found if I manually delete a symlink and replace it using the full path: sieve-filterfile -> /home/mail/domain.org/user(a)domain.org/roundcube.sieve then everybody is happy. So I'm looking to make a configuration change (and then change all existing symlinks.) I just wanted to check with the list about the two settings we return as part of the user_query: concat(homedir, maildir, 'sieve-filterfile') as sieve, concat(homedir,maildir) as sieve_dir In testing it seems like changing 'sieve' to return not the whole path but just the link name, actuall causes pigeonhole to properly make the symlink with full path! Does this seem right? FreeBSD (8.4) dovecot-pigeonhole (0.4.3_1) dovecot2 (2.2.13_3) Benjamin

Is atomic MOVING of messages between IMAP folders possible?
by Greg Sullivan 07 Aug '14

07 Aug '14

I would like to use a shared IMAP account, with multiple users accessing it simultaneously. The users would take ownership of messages by first attempting to MOVE the messages from the Inbox, into their private IMAP folder, still within the same account. Now, since there will be multiple users competing for the same messages, I naturally want only ONE of the simultaneous moves to be successful at a time. So far, this isn't working. If I do the move from two clients, simultaneously, the messages can go to *both *destination folders - duplicates can result. Is it possible to configure Dovecot and/or an IMAP client to behave the way I want it to? If the answer to this is YES, then I'll offer my config details. If the answer is NO, the next question is - do any email systems at all behave the way I want? (I tried a hosted Exchange/OWA service - it has the same problem) Thanks & regards, Greg.

Panic on alway_bcc mail with attachment while using sdbox

Important emails
by André Rodier 06 Aug '14

06 Aug '14

Hi, Sorry if I am not posting on the right mailing list, but I need email and especially IMAP experts opinion. I have developed a small perl script for Amavis that tries to recognise business emails from bulk & mailing lists, in order to promote 'important' emails, ala google. This is a feature I found very useful in corporate environments, where a lot of users are receiving advertisements, but not consider it as spam. (For info, the code is here: https://github.com/arodier/emclass) My script add an email header (X-Email-Type), and dovecot uses a virtual folder called 'Important' to present them. I know there is IMAP labels, and they are server side stored. I have successfully played with Thunderbird, but IMHO, it's not very reliable. The name of the label is the responsibility of the email client. As a result, if one client decided that $Label1 is 'Important', and $Label2 is 'Business', other clients should be configured exactly the same. I wonder if there is some norm - or convention - to attach labels to email headers, or if such a header exists, for instance a header called e.g. 'X-Tags', 'X-Keywords' or 'X-Labels'. So, once stored, an email could contains - for instance - a header like this: X-Tags: Travel,Advertisement,France. Then, it would be easy to have server side search for labels. Thanks for your feedback. Kind regards, André.

maildir: could lda/lmtp log filenames?

hello, on a mailstorage server receiving messages per lda/lmtp I like to pimp my logfile. when starting to search for a specific message I have a queueid.

Any ideas? Andreas

Hi Steffen, but I have not set-up any namespace separator, so I understand that all namespaces use the default one, right? :-S Do you think I should better use the next command? dsync -u "user(a)domain.org" mirror maildir:/mnt/vmail/domain.org/user:LAYOUT=fs Felix On Tuesday 05 August 2014 12:07:16 Steffen Kaiser wrote: > On Tue, 5 Aug 2014, Felix Rubio Dalmau wrote: > > > But it replies this answer, that I do not understand: > > > > dsync(user(a)domain.org): Error: Mail locations must use the same virtual mailbox hierarchy separator (specify separator for the default namespace) > > > > http://wiki2.dovecot.org/Namespaces > > "You should use the same hierarchy separator for all namespaces.

Migrating from maildir to mdbox
by Felix Rubio Dalmau 05 Aug '14

05 Aug '14

Hi all, I have (I think) migrated my dovecot mail format from maildir to mdbox. I have changed in 10-mail.conf the format from maildir to mdbox, and I have executed this command for all my users: dsync -u user(a)domain.org mirror maildir:/mnt/vmail/domain/user The only output of the command has been, for some users, this: dsync(user(a)domain.org): Warning: quota: Namespace '' is not Maildir, skipping for Maildir++ quota Is this important? How can I check that I am effectively using the new format? Thank you, Felix

Migrating from maildir to mdbox
by Felix Rubio Dalmau 05 Aug '14

05 Aug '14

Hi everybody, I have a virtual user setup that is using maildir, and I'd like to migrate it to mdbox. Following directions from http://wiki2.dovecot.org/Migration/MailFormat and keeping in mind that my maildir is in maildir:/mnt/vmail/%d/%u, after having updated 10-mail.conf I have tried to execute: dsync -u "user(a)domain.org" mirror maildir:/mnt/vmail/domain.org/user But it replies this answer, that I do not understand: dsync(user(a)domain.org): Error: Mail locations must use the same virtual mailbox hierarchy separator (specify separator for the default namespace) What am I doing wrong? Thank you, Felix

dovecot-lda 2.2.13 crashing when sieve_before used
by Christoph Lechleitner 05 Aug '14

05 Aug '14

Hi together! We use dovecot under Debian wheezy amd64, using the repository ... deb http://xi.rename-it.nl/debian/ stable-auto/dovecot-2.2 main Yesterday's routine upgrade to version 2:2.2.13-1~auto+130 (or some other upgrade that came along from Debian?) introduced a problem with mail delivery, which I was able to track down to a crash of dovecot-lda. Whenever I do something like ... /usr/lib/dovecot/dovecot-lda -d christoph.lechleitner(a)iteg.at <test.msg ... (with test.msg containing a raw e-mail message), dovecot-lda crashes. The gdb backtrace is: #0 buffer_free (_buf=_buf@entry=0x242eb20) at buffer.c:145 #1 0x00007f30d47ea4fd in array_free_i (array=0x242eb20) at /build/dovecot-8Ko2hw/dovecot-2.2.13/src/lib/array.h:108 #2 sieve_file_script_sequence_destroy (seq=0x242eb10) at sieve-file-script-sequence.c:242 #3 0x00007f30d47c963e in sieve_script_sequence_free (_seq=_seq@entry=0x7fffe2dbe900) at sieve-script.c:686 #4 0x00007f30d4a3d4b3 in lda_sieve_multiscript_get_scripts (svinst=svinst@entry=0x242abe0, label=label@entry=0x7f30d4a3e7c0 "sieve_before", location=location@entry=0x2416500 "/etc/dovecot/sieve/discard-viruses.sieve", scripts=scripts@entry=0x7fffe2dbe9b0, error_r=error_r@entry=0x7fffe2dbe998) at lda-sieve-plugin.c:271 #5 0x00007f30d4a3d7e5 in lda_sieve_find_scripts (srctx=0x7fffe2dbea40) at lda-sieve-plugin.c:740 #6 lda_sieve_deliver_mail (mdctx=<optimized out>, storage_r=0x7fffe2dbec00) at lda-sieve-plugin.c:973 #7 0x00007f30d5e05464 in mail_deliver (ctx=ctx@entry=0x7fffe2dbec70, storage_r=storage_r@entry=0x7fffe2dbec00) at mail-deliver.c:400 #8 0x0000000000402a92 in main (argc=3, argv=0x2402390) at main.c:437 The problem vanishes once I remove the sieve_before script, in our case /etc/dovecot/sieve/discard-viruses.sieve The sieve script does not contain anything fancy, and it works perfectly when used as sieve_default. It seems the mere presence of a sieve_before script triggers the problem. Some environment info: As of dovecot -n, I guess only the sieve related parts are relevant, if at all: plugin { sieve = /var/vmail/%d/%n/sieve sieve_before = /etc/dovecot/sieve/discard-viruses.sieve sieve_default = /etc/dovecot/sieve/default.sieve sieve_dir = /var/vmail/%d/%n/sieve-scripts } I also tried version 2:2.2.13-1~auto+138 from the dovecot-2.2.patched repository that I stumbled over while browsing the repository server. No difference regarding our problem. Our filesystem is ext4 disguised as simfs by the OpenVZ virtualization kernel. I'm pretty sure the filesystem does not matter with our problem. I'd be happy to re-test with testing releases, but I'd like to avoid setting up a full-blown test environment where unstable and bleeding edge versions would be ok.

Set an archive folder for every user
by Felix Rubio Dalmau 05 Aug '14

05 Aug '14

Hi everybody, I have a running postfix+dovecot installation, running flawlessly. The machine this setup is running onto has 2 mirrored SSD disks (in which dovecot stores the mails) and 2 mirrored regular HD. I'd like to keep the fresh emails in the SSD, and move them to an Archive folder after some days/weeks. Is there any way in dovecot to set up a folder for every user, that points to an external disk rather than the default one? Thank you, Felix

prefix behavior with Dovecot / Squirrelmail
by Will Yardley 05 Aug '14

05 Aug '14

Old: Dovecot 1.1.18 + Squirrelmail 1.4.8 + Imapproxy New: Dovecot 2.2.10 + Squirrelmail 1.4.22 (no Imapproxy) In both, we have: [dovecot config] namespace private { separator = . prefix = Mail. inbox = yes } (The 'Mail' prefix is set this way for compatibility reasons) $imap_server_type = 'dovecot'; $default_folder_prefix = 'Mail.'; $trash_folder = 'Mail.Trash'; $sent_folder = 'Mail.Sent'; $draft_folder = 'Mail.Drafts'; $show_contain_subfolders_option = true; $default_sub_of_inbox = false; (I know some of these are redundant with $imap_server_type, but that's how it's setup now). This works as we expect with the old setup - folders are set in, e.g., $maildir/.Sent, and we only see one set of each. With the newer one, it auto-creates folders as Mail.{Trash,Sent,Drafts}, which translates into Mail.Mail.{Trash,Sent,Drafts}. If I set $foo_folder to just 'Foo' (e.g., $trash_folder = 'Trash';), the auto-creation works as expected, however, now I have two sets of folders (one indented) in the folder list, and the set linking to Mail.{Trash,Sent,Drafts} (the indented ones), don't work. What's the easiest way to get the new setup working in a way that will cause the least change (preferably no change) to end-users. TIA w

Solr indexing appends domain to users
by G H 04 Aug '14

04 Aug '14

My users are set up as "admin", "john", etc -- as opposed to john(a)example.com. When I run test command "/usr/libexec/dovecot/dovecot-lda -d admin < /tmp/mymail.txt", the mail is successfully imported with Solr, Tika (yay). However, results are never found when I search within IMAP. Why? Dovecot is appending the domain name to the user and admin fields of the Solr record ("admin(a)example.com" instead of just "admin") during index. But during searching, Dovecot is only searching for the user directly, from the Solr logs: q=body:"TESTCONTENT"&fq=%2Bbox:7dff0b0d4f84df53f25300003d823887+%2Buser:"admin" If I rerun the query via the Solr web gui with user:"admin(a)example.com", the message is found. How do I disable appending the domain name to the solr index names? Thanks, G H

I'm getting 2 errors which are probably related, the second of which I haven't actually seen an issue with yet (I just found it looking at the error log) The issue is that I cannot change my subscriptions through Thunderbird (version 31.0). I created the subscriptions through Thunderbird, but now it won't let me change them. dovecot responds with sutff like this when I sniff network traffic or configure Thunderbird to log IMAP traffic: 10 NO [NOPERM] No permission to modify subscriptions The time stamp on the .subscriptions.lock file gets updated every time I try to make a change. To test I edited .subscriptions by hand and forced Thunderbird to try to subscribe something and I got access to the folder I added, so I presume it is reading the file correctly. Permissions on~jreid/mail is 0700, the existing .subscriptions file is 0640 and .subscriptions.lock file is 0600. all the files are owned by me and their group is my primary group (not mail). As for the second error, the dovecot.index.log.newlock file gets created but no dovecot.index.log file gets created. And dovecot would have created the directory tree to those files itself... I'm new to dovecot but not Unix or IMAP so I'm sure this is just some configuration option I've missed, any help would be most appreciated. $ /opt/csw/bin/doveconf -n # 2.2.12: /etc/opt/csw/dovecot/dovecot.conf # OS: SunOS 5.11 i86pc disable_plaintext_auth = no first_valid_uid = 100 mail_access_groups = mail mail_location = mbox:~/mail:INBOX=/var/share/mail/%u 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_cert = </etc/opt/csw/ssl/certs/dovecot.pem ssl_key = </etc/opt/csw/ssl/private/dovecot.pem userdb { driver = passwd } $ doveadm log errors [...] Aug 03 16:47:02 imap(jreid): Error: rename(/home/jreid/mail/.subscriptions.lock, /home/jreid/mail/.subscriptions) failed: Permission denied Aug 03 16:52:49 imap(jreid): Error: rename(/home/jreid/mail/2012/.imap/Received/dovecot.index.log.newlock, /home/jreid/mail/2012/.imap/Received/dovecot.index.log) failed: Permission denied -- joe

Dovecot with dbox indexing weirdness
by Coert 04 Aug '14

04 Aug '14

Hello all, I run a local dovecot imap server, with dbox storage in my home directory. It works well, but everytime I restart the machine, it seems according to lsof to reindex everything (and I am sitting with 250k mails). Is this the intended behaviour? I would expect it to happen only once or on update of a folder? regards, Coert

When running Dovecot with Postfix under Virtualmin on my VPS, I was wondering if there was a way for it to handle a separate certificate for each domain and IP address? Thank you.

autocreate mailboxes
by Mike Pultz 02 Aug '14

02 Aug '14

Hello, I just upgraded to Dovecot 2.2.13 from the 2.0 version branch- so far everything is working great. I wanted to take advantage of the mailbox option to auto create and auto subscribe users to a Sent and Trash folder (using the support for the special use flags), but ideally, I only want to do this for new mailboxes, and not for all the mailboxes that already exist on the system. The reason for this is because all the existing users likely already have a sent-mail folder configured, and I don't want to implement this, and have their sent-mail folder switched to this new one. When I set this up on my test system, I noticed that the new sent and trash folders appeared in my existing mailbox, and when I checked the account on my iPhone, it switched my sent-mail folder away from my "normal" sent-mail folder, and I couldn't change it back. Is there a way to do this ONLY when dovecot creates a new mailbox? Thanks, Mike

Advantage of LMTP
by Jerry 02 Aug '14

02 Aug '14

Sat, 2 Aug 2014 06:53:58 -0400 Presently, I have: "virtual_transport = dovecot" in my Postfix main.cf file and dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/local/libexec/dovecot/dovecot-lda -f ${sender} -d ${recipient} in the master.cf file. Is there any advantage to using LMPT instead? All of my users are configured as virtual users. If I change it, do I have to eliminate the above from my master.cf file? -- Jerry

[Dovecot] Converting old emails to compressed format
by Renaud Allard 02 Aug '14

02 Aug '14

Hello, I know this question has already been asked, but I would really like a solution here as I tried all I could find on the wiki or mail archives I am now running dovecot 2.2.12 Compression works fine for new mails, so zlib works Mails are currently stored using dbox So I tried for testing dsync -D -v mirror -u user -m Archives dbox:~/temp dsync -o "plugin/zlib_save=xz" -D -v mirror -u user -m Archives dbox:~/temp dsync -o "plugin/zlib_save=" -D -v mirror -u user -m Archives dbox:~/temp dsync -o "plugin/zlib_save=" -D -v mirror -u user -m Archives maildir:~/temp dsync -o "plugin/zlib_save=xz" -D -v mirror -u user -m Archives maildir:~/temp And also converting again those maildir messages to dbox (just in case it wouldn't work from dbox format) And also with backup instead of mirror None of this actually works, mails are indeed copied, but not compressed So I am wondering if there is a way to compress those mails? Thank you

Configuring pigeonhole/sieve
by Timothy Murphy 02 Aug '14

02 Aug '14

I've been trying for a few days to get pigeonhole/sieve working in order to filter email with spamassassin. Unfortunately I have had no success; and I have found no document which simply tells me what changes I need to make to which files, and what other action I have to take. I'm running CentOS-7 on my home-server, and have postfix + dovecot working perfectly; moreover spam is marked with ***Spam*** added to the Subject header. The only problem is that this spam is getting through to my inbox. It's clear that I'm overlooking some action I should be taking, and I'm sure there must be a document somewhere that gives simple and complete instructions on setting up pigeonhole/sieve to work with SpamAssassin. If anyone knows of such a document I should be eternally grateful. I was told at one point that "You need to pass your mail through dovecot-lda or lmtp", but I have no idea what this means. I see in /var/log/dovecot when I re-start dovecot "Aug 02 00:13:04 master: Info: Dovecot v2.2.10 starting up for imap, pop3, lmtp, sieve, sieve (core dumps disabled", which seems to imply that lmtp is enabled. Any suggestions or advice gratefully received. -- Timothy Murphy e-mail: gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin 2, Ireland

Dovecot EE on SciLinux 6.5: No Config Files in /etc
by Asai 02 Aug '14

02 Aug '14

Greetings, I tried installing Dovecot EE on Scientific 6.5 yesterday, but there was no repo under that release version, so I hardcoded the release version to 6 in yum.repos.d/dovecot.repo. That worked, but when I installed, it didn't install any default configuration files. /etc/dovecot was empty. Is that to be expected for EE? -- --Asai

Are you implying that Dovecot 2.1.7 doesn't enable persistent modseq tracking in this case? I never claimed that earlier versions of Dovecot didn't advertise CONDSTORE or didn't implement it properly, etc. Perhaps I should have written "...after *any* of the two commands... (and maybe others)" -- meaning it does after either of those two commands, and the other ones I don't care about and so didn't test. > And as mentioned above, there are 6 different ways of enabling CONDSTORE. > (Enabling QRESYNC is done 1 way ... the "ENABLE QRESYNC" command). Yes, agreed, noted. I'm asking about two out of those five / six. And not just about what the RFC says, but about how real, out in the field, installed on mail servers that people use, possibly quite old, versions of Dovecot behave. So let me try again: Is sending SELECT ... (CONDSTORE) or STATUS (... HIGHESTMODSEQ ...) enough to enable reliable persistent modseq tracking for all versions of Dovecot which advertise CONDSTORE in their capabilities? Not what the currently relevant RFC says, but how Dovecot versions with CONDSTORE in their caps behave. This is the one thing I'd really like to know. > > > So my questions are: >> >> 1 - Is this (enabling persistent modseq) also the case for all Dovecot >> versions prior to 2.1.7 that advertise CONDSTORE? >> >> There must be people running older versions out there, older than 2.1.7. >> >> If not, how can I branch my logic to not use HIGHESTMODSEQ, given that >> Dovecot doesn't appear to return any version info via its greeting or via >> the ID command? >> > > As noted above, this is irrelevant.

However: > Returning NOMODSEQ on mailboxes that don't support persistent > mod-sequences has worked since 1.2.0, at least as far as I know. The linked message from 2012, discussing 2.0.18, says: "2) If a mailbox doesn't have modseqs enabled, return NOMODSEQ. This isn't ideal, but seems like the only possibility" And based on my tests, Dovecot 2.1.7 returns "HIGHESTMODSEQ 1" for mailboxes where modseq tracking has not been enabled. You're largely right about the value only being relevant if the client enabled CONDSTORE, and I don't care too much about this quirk, just wanted to to get a clarification on this as well, if possible.

Differences in "Delivered-To" header between deliver and LMTP
by Jeff Rice 01 Aug '14

01 Aug '14

Hi, I'm transitioning my server over from using the deliver LDA and LMTP. Suddenly a bunch of sieve filters stopped working, and I noticed the contents of the Delivered-To header are different. Using Dovecot's deliver LDA, the contents are a bare email address (foo(a)bar.com) Using Dovecot LMTP, they are in brackets (<foo(a)bar.com>). Is there a reason why this isn't consistent between the two delivery agents? It seems like it ought to be. Jeff

solr_add_definite_query quotes queries
by G H 01 Aug '14

01 Aug '14

So Solr 4.0 and higher supports regular expressions in searching. However, Dovecot is quoting search queries in solr_add_definite_query (via solr_add_str_arg). This breaks regex searching. I do a sample search for emails with "merged" in their body via the query /merg.*/. If you look at the Solr logs, it is sending: q=body:"/merg.*/" which is converted to body:\"/merg.*/\" inside Solr. but if it had sent only: q=body:/merg.*/ then regex would have worked. Is regular expression searching on the dashboard? I'm considering patching fts-backend-solr.c to not quote-enclose the search, but am looking for any better suggestions. Or perhaps not quote-enclose if the search is prefixed with RX: (ie: "RX:/merg.*/")... Thanks, G H

Hello everyone, We have Dovecot 2.1.6 and Pigeonhole 0.3.0. We would like Pigeonhole not to send the vacation response to noreply(a)whatever.com<mailto:noreply@whatever.com>. In this wiki http://wiki2.dovecot.org/Pigeonhole/Sieve/Usage#Vacation_auto-reply are showed the different exceptions, but the noreply is not in there. How can I add this address, or another one, to this exception list? Thank you very much in advanced. Kind regards. Héctor Moreno.

Solr 4+ schema.xml?
by G H 31 Jul '14

31 Jul '14

Does anyone have a Solr 4+ compatible schema.xml for dovecot indexing? I am trying to test to see if regex-based FTS searching works through IMAP, but Solr 4.9.0 is throwing an error, "SolrException: undefined field text", on startup with the schema.xml included with Dovecot 2.2.9. Thanks. G H

Issue with exim and auth protocol
by Mildred Ki'Lya 31 Jul '14

31 Jul '14

Hi, I'm trying to set up exim (4.83) as a submission server, and need to set up the dovecot authentication in exim. I'm having an issue with that (documented at <https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=756258>) The problem is that exim doesn't follow the handshake as described here: <http://wiki2.dovecot.org/Design/AuthProtocol>. The wiki page says that the client should start the handshake, but exim waits for the server to start and to receive the DONE command until it starts its own handshake. What I actually get is: exim connects to dovecot auth dovecot VERSION 1 1 dovecot SPID 48 And then, dovecot stops (I presume it waits for the client handshake, VERSION and CPID). Exim on its side waits for the DONE. This results in the SMTP connection by exim never replying to the AUTH PLAIN command. This is exim 4.80 (or 4.83) and dovecot 2.1.7. I have another server set up almost exactly the same (but with dovecot 2.1.17) where it does work. In that case, dovecot finishes the handshake before exim starts its handshake. It results in: exim connects to dovecot auth dovecot VERSION 1 1 dovecot MECH PLAIN plaintext dovecot SPID 10905 dovecot CUID 1 dovecot COOKIE d3861d29441f06d962490eab8549fd46 dovecot DONE exim VERSION 1 0 exim CPID 10619 exim AUTH 1 PLAIN service=smtp secured rip=82.247.184.53 lip=80.67.179.36 nologin resp=<base64 encoded string> I don't understand what could change the dovecot behaviour in that regard. Is there a solution that would only require modifying the configuration? Thank you, Mildred
