[Dovecot] Dovecot 2.1.10
by Ralf Zimmermann 14 Nov '12

14 Nov '12

Hi all, I've a problem with dovecot-2.1.10. At time we use dovecot-1.2 without zlib. We setup a new server with dovecot 2.1.10. After syncing the emails everything looks fine. But if we use zlib plugin all new emails have no content. There are a lot of "Error: Maildir filename has wrong S value" log entrys. So we have compiled dovecot-2.0.18 and we use exactly the same configuration. Everything works. What can be our problem with version 2.1.10? Greets Ralf

[Dovecot] dovecot lost mail! Cause?
by Lukas Haase 14 Nov '12

14 Nov '12

Hi, After using dovecot for several years now, today happend something which makes me really feel unconfortable: An email received was just not delivered properly, or, is lost! The mail (from an external server) was sent to two local mailboxes, user1 and user2. user1 received the message but for user2, it *magically* disappeared. MTA is exim4 which definitely processed the messages and handed over to dovecot deliver: 2012-11-12 07:28:21 1TXnVG-00053I-GD SA: [...] id=8644593.887351352701 685934.JavaMail 2012-11-12 07:28:21 1TXnVG-00053I-GD => user1 <user1(a)example.com> R=dovecot T=dovecot_pipe 2012-11-12 07:28:21 1TXnVG-00053I-GD => user2 <user2(a)example.com> R=dovecot T=dovecot_pipe 2012-11-12 07:28:21 1TXnVG-00053I-GD Completed Also, the log of dovecot tells that the mail should have been stored: Nov 12 07:28:21 mail dovecot: deliver(user1): sieve: msgid=<8644593.887351352701685934.JavaMail>: stored mail into mailbox 'INBOX' Nov 12 07:28:21 mail dovecot: deliver(user2): sieve: msgid=<8644593.887351352701685934.JavaMail.orbitz>: stored mail into mailbox 'INBOX' user1 received the mail but user2 not. Since user2 is myself, I *know* that I did not accidently delete any mail or something like that. It was just never received! Disk space is 3GB left, so enough. So I grepped the whole Maildir of user2 for the message ID. There is only one match in the dovecot.index.cache and within that, the most important data of the mail (Message ID, Date, Sender, Receiver, Subject) appears. But apart from that, not a single file! Is there hope to ever find out why what was going wrong here? It feels me veeeeeeeeery unconfortable because from now on I can never be sure any more that all my mails are really received :( :( However, as I said, my mail system processed maybe millions of messages the past 8 years. Although, I can not be sure if that was the case ... :( And help greatly appreciated! Luke PS: Dovecot version 1.2.15 (Debian 6.0.6) with Maildir backend on local harddrive. No NFS, nothing which can go wrong ... PPS: Original log files, just named replaced for privacy.

[Dovecot] Dovecot newbie (migrating from qmail)
by Ajai Khattri 13 Nov '12

13 Nov '12

Ive been using qmail+vpopmail+courier-imap for many years but its time to retire that server so I thought this might be an opportunity to see how I could use Postfix and Dovecot to provide the same services. Im running Dovecot 2.1.9 and Postfix 2.9.4. I have spent a few days reading through some of the docs on the wiki (there's doesn't seem to be any large overview of Dovecot concepts or books so bear with me). Im thinking something simple like passwd-file setup would suffice for me. I want to use completely virtual users. Id like to store mail under /home/vmail/$domain/$user. I think Ive figured out how to do that. But how do I create the maildir? I understand the need to have a mail directory but also a directory for things like sieve - how to specify that? Im thinking the structure would be something like: /home/vmail/$domain/$user/mail <-- mail stored here /home/vmail/$domain/$user/ <-- sieve and other sundry store here Or should the sieve stuff also be under its own folder alongside the maildir? Is it possible to have a separate passwd file per domain? It is possible to combine password and userdb files into one per domain? (I prefer to keep all files related to each domain in its own folder). Also would like to configure Postfix to use dovecot-sasl and I want to use dovecot-lmtp for deliveries. Any good docs / example on those? Later on, I think I want to integrate some kind of virus and spam filtering (amavisd and maybe dspam - anybody used those? would I configure Postfix to handle that or dovecot-lmtp?) Im sure Ill have more questions as I get more complicated but baby steps for now. -- Aj.

[Dovecot] Commercial features in Dovecot future: Object storage, archive
by Timo Sirainen 13 Nov '12

13 Nov '12

Hi all, Dovecot Oy’s web pages at www.dovecot.fi have been updated. The products page lists two features that will be available for commercial licensing, extending the functionality of the basic open-source version of Dovecot. * Storing emails to (high-latency) object storage, initially supporting Amazon S3, Caringo CAStor and Scality. * Email archive storage. See http://www.dovecot.fi/products/index.html for details. I’ve been developing Dovecot for over 10 years now. For a long time it was my primary motivation in life to create the best IMAP server available :) I think I've pretty much accomplished that by now. The future is looking very bright for Dovecot: we will continue the open source development stronger than ever, but in addition, for the long term it needs some additional licensed components that bring the money to cover the cost for future Dovecot development and to be able to build up the support in a professional way. These new features will be added as plugins on top of Dovecot to extend the functionality. Note that I’m not just randomly choosing which features will be open and which will be licensed. Only some specific features will be licensed where my company is going to make money with partnerships and in other measurable ways.

[Dovecot] mbox vs. maildir storage block waste
by Christoph Anton Mitterer 13 Nov '12

13 Nov '12

Hi. I recently mentioned in several posts, that I'd tended to use mbox rather than maildir, because you don't loose so much space (due to always allocating full blocks per maildir file and thus per mail). I made some tests of my archive, which consists of some 3,4 million mails at a total of 42GB). Most of these mails are probably normal sized, but there are also some with bigger attachments. For those who are interested here are the results: I used a 53687091200 B image file (via loop device) and tested ext4 only. btrfs is IMHO not yet ready, I have had often issues with XFS (corruptions), reiser4 is more or less dead and reiser3 is said to have issues (see e.g. its wikipedia article, even though it has that mode for small files which would fit nicely). As you see the number of mails increased a bit, cause I tested over several days... but this is only a very small increase so it shouldn't change the numbers a lot. 1) Original mbox archives (right now in Evolution) mbox exact space: 38122676224 (does not include meta-data) mbox guess space: 44625670144 (includes Evolution meta-data which is several GBs) mbox num mails: 3412999 (occurances of From_ lines) In the following: - image file, 1B-blocks, Used_begin, Used_end, Available_begin, Available_end result out of df -B 1 - mdir exact used space is the sum of du -B 1 for each regular file (i.e. each mdir file) - mdir guess used space du -B 1 on the root dir of the filesystem - mdir num mails: find . type -f | wc -l on the root dir of the filesystem 2) EXT4 with 4096 blocks: image file: 53687091200 1B-blocks: 52844687360 Used_begin: 188555264 Used_end: 45198778368 Available_begin: 49971777536 Available_end: 2444972032 mdir exact used space: 44810866688 mdir guess used space: 45010243584 mdir num mails: 3423296 delta: 6.688190464 G delta / mail: 1953 B 3) EXT4 with 2048 blocks: image file: 53687091200 1B-blocks: 50324295680 Used_begin: 82857984 Used_end: 41598846976 Available_begin: 47557083136 Available_end: 6041094144 mdir exact used space: 41323991040 mdir guess used space: 41516007424 mdir num mails: 3425033 delta: 3.201314816 G delta / mail: 934 B 4) EXT4 with 1024 blocks: image file: 53687091200 1B-blocks: 50314834944 Used_begin: 38287360 Used_end: 39909360640 Available_begin: 47592193024 Available_end: 7721119744 mdir exact used space: 39683908608 mdir guess used space: 39871086592 mdir num mails: 3425033 delta: 1.561232384 G delta / mail: 455 B As you can see, the delta per mail is rather close to the statistically expected values of 2048B, 1024B and 512B. In the end I probably changed my opinion. ~7GB of wasted block space for all my mails is actually quite a lot, but in days of cheap disk space it's acceptable. And with mbox one has IMHO the major disadvantage that mailservers (including dovecot) store some meta-data _in_ it (i.e. in the mails themselves) , which I don't like a lot. I still think about reports that mbox is much faster with full text search (which sounds reasonable)... but therefore one needs probably and database backend anyway. HTH, Chris.

[Dovecot] Invalid Managesieve commands are counted twice
by Christoph Bußenius 12 Nov '12

12 Nov '12

Hi, the Managesieve server closes the connection if it receives an unknown command before authentication: "IMPLEMENTATION" "Dovecot Pigeonhole" "SIEVE" "fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave" "NOTIFY" "mailto" "SASL" "PLAIN" "STARTTLS" "VERSION" "1.0" OK "Dovecot ready." --> BOGUS NO "Error in MANAGESIEVE command received by server." NO "Error in MANAGESIEVE command received by server." BYE "Too many invalid MANAGESIEVE commands." Connection closed by foreign host. Note that only one bogus command has been sent by the client, however the server sends two identical error messages. This seems to be a bug in Pigeonhole 0.3.3. In version 0.2.6, the connection was kept open after the error message. This is actually important to us because we use the "sieveshell" utility which is shipped with the Python "managesieve" package. The managesieve.py module always sends a BOGUS command after the TLS handshake. According to its comments, this is done to work around problems with other server implementations: # Some servers send capabilities after TLS handshake, some # do not. We send a bogus command, and expect a NO. If you # get something else instead, read the extra NO to clear # the buffer. typ, data = self._command('BOGUS') (The full source is at http://pydoc.net/managesieve/0.4.2/managesieve) As a result, sieveshell cannot be used with TLS and a current Dovecot/Pigeonhole server.

[Dovecot] Solr 4.0 - lucene - FTS
by Charles Marcus 12 Nov '12

12 Nov '12

Hi Timo, As one who is interested in implementing FTS sometime in the future, I'm curious about what is in store as far as improvements go... Specifically, any plans for implementing immediate/automatic index updates at delivery time? The lack of automatically updated indexes is one downside for its implementation... Also, does the release of Solr 4.0 mean anything for the lucene library used by dovecot? http://www.marketwatch.com/story/lucidworks-congratulates-apache-foundation… Thanks, -- Best regards, Charles

[Dovecot] Sieve puts incoming message into inbox on any problem with submission_host
by Christian Rohmann 12 Nov '12

12 Nov '12

Hello dovecot-users, I have a question/suggestion regarding the submission_host feature of the lda (either via dovecot-lda binary or lmtp) in combination with sieve. When trying to deliver message to a mailbox and this message has a sieve redirect action applied to it, dovecot is using the configured smtp server to forward the message just fine. Unfortunately, if the server configured for submission is unavailable, returns an error or cannot be found via DNS, sieve will simply put the message into the inbox and be done with it: --- dovecot.log --- dovecot: lda(user1): Error: lmtp client: DNS lookup of idonotexist.example.com failed: Name or service not known dovecot: lda(user1): Error: sieve: msgid=unspecified: failed to redirect message to <user2> (refer to server log for more information) dovecot: lda(user1): sieve: msgid=unspecified: stored mail into mailbox 'INBOX' dovecot: lda(user1): Error: sieve: execution of script /mailboxes/user1/.dovecot.sieve failed, but implicit keep was successful (user logfile /mailboxes/user1/.dovecot.sieve.log may reveal additional details) --- /dovecot.log --- The same applies to vacation messages being sent out. Especially with an (unconditional) redirect action, users don't expect to find messages in their inbox. Also problems with the submission_host could very much be temporary and a little delay in delivering a message is better then putting it somewhere the user doesn't expect a message to be. Is there any way to change the behavior of dovecot or the sieve plugin to tempfail in case a message cannot be sent out? I know that with multiple sieve actions it gets more complicated as there could be corner cases were the first message can be sent via the submission server and another message produced by the same sieve script cannot. I'd love sieve to behave like this: a) if submission host is unreachable (hostname wrong, timeout, ...) -> tempfail b) if submission host returns 4xx error -> tempfail c) if submission host returns 5xx error -> fail(-save) and just drop the message into inbox or even have an option to reject the message completely in this case. In case of a tempfail response, the mta simply queues the message and tries again later. In case of a permanent fail the mta will create a bounce message to in form the sender. Regards and have a great weekend, Christian

[Dovecot] doveadm quota get -A via doveadm-proxy director with LDAP
by Ramon Frontera 10 Nov '12

10 Nov '12

Hi, We are running Dovecot 2.1.10 I want configure dovecot to do execute doveadm commands on the proxy server. We have 1 proxy with director and 2 mail servers. we use LDAP when I try to do doveadm quota get -u user it works fine. The problem is when I try to do doveadm quota get -A ON PROXY I have this result: doveadm(first_user): Error: Proxy is missing destination host doveadm: Error: Failed to iterate through some users Username Quota name Type Value Limit % in 10-auth.conf I have "!include auth-ldap.conf.ext" in auth-ldap.conf.ext I hve: passdb { driver = ldap args = /etc/dovecot/dovecot-ldap.conf.ext } userdb { driver = ldap args = /etc/dovecot/dovecot-ldap.conf.ext } and In dovecot-ldap.conf.ext I have: uris = ldap://ldap:port dn = xxxxx dnpass = yyyyy auth_bind = no ldap_version = 3 base =base scope = subtree user_attrs = attributes user_filter = (mail=%u) pass_attrs = userPassword=password,uid=user=%L$,cn=proxy,=starttls=any-cert pass_filter = (mail=%u) iterate_attrs = uid=user iterate_filter = (uid=*) I don't know where is my error!!!

[Dovecot] quota recalc does not work
by Adrian Stoica 09 Nov '12

09 Nov '12

Hi I upgraded dovecot from 2.0 to 2.1 , and now i face the quota recalc problem. All settings are keep in mysql Before , after a change in mailbox.quota field, i run doveadm quota recalc and all was ok , but now that command doesn't do anything. After i change a quota for a user , i have to restart dovecot to get the new quota , or do a "doveadm reload" instead of recalc. And the doveadm quota recalc -A" give me back a lot of "doveadm(username): Info: User no longer exists, skipping" Any thoughts ? # 2.1.10: /usr/dovecot21/etc/dovecot/dovecot.conf # OS: Linux 2.6.35.4 i686 auth_cache_negative_ttl = 1 secs auth_cache_size = 2 M auth_failure_delay = 4 secs auth_mechanisms = plain login digest-md5 cram-md5 auth_worker_max_count = 100 base_dir = /var/run/dovecot/ default_client_limit = 4096 default_internal_user = vmail default_login_user = nobody default_process_limit = 256 deliver_log_format = mail delivery from=%f subject=%s msgid=%m: %$ dict { acl = mysql:/usr/dovecot21/etc/dovecot/dovecot-dict-sql.conf.ext } disable_plaintext_auth = no first_valid_uid = 1 lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes listen = * mail_location = maildir:~/Maildir mail_plugins = " quota acl trash notify mail_log" 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 { hidden = no list = children location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u prefix = shared/%%u/ separator = / subscriptions = no type = shared } namespace inbox { inbox = yes list = 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 = / subscriptions = yes type = private } passdb { args = /usr/dovecot21/etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { acl = vfile acl_shared_dict = proxy::acl autocreate = Trash autocreate2 = Drafts autocreate3 = Sent autosubscribe = Trash autosubscribe2 = Drafts autosubscribe3 = INBOX autosubscribe4 = Sent mail_log_events = delete mailbox_delete mailbox_rename mail_log_fields = box subject from msgid size quota = maildir:User quota quota_warning = storage=95%% quota-warning 95 %u quota_warning2 = storage=95%% quota-warning 90 %u quota_warning3 = storage=85%% quota-warning 85 %u sieve = ~/.dovecot.sieve sieve_dir = ~/sieve trash = /usr/dovecot21/etc/dovecot/dovecot-trash.conf.ext } postmaster_address = postmaster(a)dacris.net protocols = imap quota_full_tempfail = yes rejection_subject = Rejected: %s: %r service auth { unix_listener auth-client { mode = 0666 user = vmail } unix_listener auth-userdb { mode = 0666 user = vmail } } service dict { unix_listener dict { user = vmail } } service imap-login { process_min_avail = 4 } service imap-postlogin { executable = script-login /bin/imap.sh unix_listener imap-postlogin { mode = 01232 } } service imap { executable = imap imap-postlogin process_limit = 1024 vsz_limit = 1 G } service quota-warning { executable = script /bin/quota_warning.sh unix_listener quota-warning { user = vmail } user = vmail } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = /usr/dovecot21/etc/dovecot/dovecot-sql.conf.ext driver = sql } protocol lda { mail_plugins = " quota acl trash notify mail_log sieve autocreate" } protocol imap { imap_client_workarounds = delay-newmail mail_max_userip_connections = 20 mail_plugins = " quota acl trash notify mail_log imap_quota imap_acl" } dovecot-sql.conf.ext: password_query = SELECT password FROM mailbox WHERE \ username = '%Ln' AND domain = '%Ld' AND \ active = '1' user_query = SELECT CONCAT('/srv/vmail/',mailbox.domain,'/%Ln') AS 'home' ,'98' AS 'uid', '98' AS 'gid' , \ CONCAT('*:storage=', mailbox.quota,'M') AS quota_rule ,"Trash:storage=+50M" AS quota_rule2 FROM mailbox WHERE \ mailbox.username = '%Ln' AND mailbox.domain = '%Ld' AND \ mailbox.active = '1' iterate_query = SELECT username AS user , domain FROM mailbox WHERE active = '1'

[Dovecot] Mails don't get deleted after POP3
by cullinan＠rocketmail.com 09 Nov '12

09 Nov '12

Hi, there! Well, I am new to dovecot, so please be patient with me: I have a virtual server and want to setup simple mail delivery. postfix, saslauthd and dovecot basically work fine. The only open issue is, that (I guess) dovecot doesn't remove the mail when it's retrieved via pop3 from the server. It keeps sending me the same emails again and again. (The mail client (Thunderbird) is configured to remove the messages from the server - it was working already.) I guess that dovecot cannot write to some files / has problems with write permissions. But it doesn't tell me anything... Can you tell me, what configuration might be wrong or how can I enable more debugging to see what dovecot is doing after the mails got sent out via pop3? Here is the configuration: # dovecot -n # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.38-8-server x86_64 Ubuntu 11.04 log_timestamp: %Y-%m-%d %H:%M:%S protocols: pop3 pop3s login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/pop3-login mail_privileged_group: mail mbox_write_locks: fcntl dotlock mail_executable: /usr/lib/dovecot/pop3 mail_plugin_dir: /usr/lib/dovecot/modules/pop3 auth default: passdb: driver: pam userdb: driver: passwd -----8<----- # dovecot -a # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.38-8-server x86_64 Ubuntu 11.04 base_dir: /var/run/dovecot log_path: info_log_path: log_timestamp: %Y-%m-%d %H:%M:%S syslog_facility: mail protocols: pop3 pop3s listen: * ssl_listen: ssl: yes ssl_ca_file: ssl_cert_file: /etc/ssl/certs/dovecot.pem ssl_key_file: /etc/ssl/private/dovecot.pem ssl_key_password: ssl_parameters_regenerate: 168 ssl_cipher_list: ssl_cert_username_field: commonName ssl_verify_client_cert: no disable_plaintext_auth: yes verbose_ssl: no shutdown_clients: yes nfs_check: yes version_ignore: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/pop3-login login_user: dovecot login_greeting: Dovecot ready. login_log_format_elements: user=<%u> method=%m rip=%r lip=%l %c login_log_format: %$: %s login_process_per_connection: yes login_chroot: yes login_trusted_networks: login_process_size: 64 login_processes_count: 3 login_max_processes_count: 128 login_max_connections: 256 valid_chroot_dirs: mail_chroot: max_mail_processes: 512 mail_max_userip_connections: 10 verbose_proctitle: no first_valid_uid: 500 last_valid_uid: 0 first_valid_gid: 1 last_valid_gid: 0 mail_access_groups: mail_privileged_group: mail mail_uid: mail_gid: mail_location: mail_cache_fields: mail_never_cache_fields: imap.envelope mail_cache_min_mail_count: 0 mailbox_idle_check_interval: 30 mail_debug: no mail_full_filesystem_access: no mail_max_keyword_length: 50 mail_save_crlf: no mmap_disable: no dotlock_use_excl: yes fsync_disable: no mail_nfs_storage: no mail_nfs_index: no mailbox_list_index_disable: yes lock_method: fcntl maildir_stat_dirs: no maildir_copy_with_hardlinks: yes maildir_copy_preserve_filename: no maildir_very_dirty_syncs: no mbox_read_locks: fcntl mbox_write_locks: fcntl dotlock mbox_lock_timeout: 300 mbox_dotlock_change_timeout: 120 mbox_min_index_size: 0 mbox_dirty_syncs: yes mbox_very_dirty_syncs: no mbox_lazy_writes: yes dbox_rotate_size: 2048 dbox_rotate_min_size: 16 dbox_rotate_days: 1 mail_drop_priv_before_exec: no mail_executable: /usr/lib/dovecot/pop3 mail_process_size: 256 mail_plugins: mail_plugin_dir: /usr/lib/dovecot/modules/pop3 mail_log_prefix: %Us(%u): mail_log_max_lines_per_sec: 10 imap_max_line_length: 65536 imap_capability: imap_client_workarounds: imap_logout_format: bytes=%i/%o imap_id_send: imap_id_log: imap_idle_notify_interval: 120 pop3_no_flag_updates: no pop3_enable_last: no pop3_reuse_xuidl: no pop3_save_uidl: no pop3_lock_session: no pop3_uidl_format: %08Xu%08Xv pop3_client_workarounds: pop3_logout_format: top=%t/%p, retr=%r/%b, del=%d/%m, size=%s dict_db_config: dict_process_count: 1 managesieve_max_line_length: 65536 managesieve_logout_format: bytes=%i/%o managesieve_implementation_string: dovecot auth default: mechanisms: plain realms: default_realm: cache_size: 0 cache_ttl: 3600 cache_negative_ttl: 3600 executable: /usr/lib/dovecot/dovecot-auth user: root chroot: username_chars: abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@ username_translation: username_format: master_user_separator: anonymous_username: anonymous krb5_keytab: gssapi_hostname: winbind_helper_path: /usr/bin/ntlm_auth failure_delay: 2 verbose: no debug: no debug_passwords: no ssl_require_client_cert: no ssl_username_from_cert: no use_winbind: no count: 1 worker_max_count: 30 process_size: 256 passdb: driver: pam args: deny: no pass: no master: no userdb: driver: passwd args: -----8<----- Please let me know if you need more.

[Dovecot] Dovecot ok for port 110, but not for SSL (beginner asking)
by ycc_Swe 09 Nov '12

Hello, I just installed Dovecot. It works for plaintext autorization, port 110. It has connected with Telnet, Thunderbird and an on-line pop3 client. Telnet: +OK Dovecot ready. user nnnnn -ERR Unknown command. user nnnnn +OK pass xxxxxxxxxx +OK Logged in. stat +OK 1 1553 retr 1 +OK 1553 octets Return-path: <sssssss(a)hotmail.com> Envelope-to: nnnnnn(a)mydomain.com Delivery-date: Tue, 06 Nov 2012 12:02:28 +0100 Received: from bay0-xcvxcv-xvxcv.bay333.hotmail.com ([123.123.123.123]) by deb7.pc with esmtp (Exim 4.80) But when I try ssl (port 995) with an on-line pop3 client, it will not work: /var/log/mail.log Nov 7 02:46:55 deb7 dovecot: pop3-login: Disconnected (no auth attempts in 0 secs): user=<>, rip=12.12.12.7, lip=123.123.123.123, TLS: Disconnected, session=<Iza75N3NlABBNykH> Nov 7 02:46:56 deb7 dovecot: pop3-login: Disconnected (no auth attempts in 1 secs): user=<>, rip=12.12.12.7, lip=123.123.123.123, TLS: Disconnected, session=<nWTF5N3NlQBBNykH> root@deb7:~# doveconf -n # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-3-686-pae i686 disable_plaintext_auth = no mail_gid = mail mail_location = mbox:~/mail:INBOX=/var/mail/%u namespace inbox { inbox = yes location = prefix = } passdb { args = username_format=%u /etc/dovecot/users driver = passwd-file } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = " imap pop3" ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = username_format=%u /etc/dovecot/users driver = passwd-file } I know very little about mail and ssl.

As you can see I am a beginner with Dovecot, I hope it is still OK to ask on this mailing list.

The current stable release is RHEL 6.3, released in June 2012. What is the valid reason preventing you from upgrading to the 6.x distribution? The packages in general in 6.x are 5 years newer than 5.x. And given the fact that RHEL runs miles behind the bleeding edge, you're way behind the curve even with a recent RHEL distribution. You can probably find a much newer version of Dovecot in an RPM somewhere, and Postfix for that matter. But it would be better for you if you simply upgraded to RHEL 6.3. -- Stan

Is there a way I can have something like the following setup: 192.168.0.2 port 110/143, with no starttls/ssl 192.168.0.3 port 110,995/143,993 with starttls/ssl 192.168.0.4 port 110,995/143,993 with starttls/ssl I am looking to setup dovecot so that some IPs will run without any notion of SSL whereas other IPs will run with with ssl/starttls available, each with its own certs

[Dovecot] pop3 exim4 dovecot
by Patrick Shirkey 08 Nov '12

08 Nov '12

Hi, I have an exim4 and dovecot system. The system has multiple accounts. Exim4 is receiving emails in the /var/mail/user files and dovecot is configured to use /home/user/mail (mbox) folder. I have one account that dovecot is not processing replies/bounces/etc... The data is being written in the /var/mail/user file by exim4 but as far as dovecot is aware there is nothing in the pop3 inbox. Can anyone suggest how I can enable dovecot to know that the data is in the /var/mail/user file and deliver it to the pop3 inbox for this account? -- Patrick Shirkey Boost Hardware Ltd

[Dovecot] v2.2.alpha1 released
by Timo Sirainen 08 Nov '12

08 Nov '12

http://dovecot.org/releases/2.2/alpha/dovecot-2.2.alpha1.tar.gz http://dovecot.org/releases/2.2/alpha/dovecot-2.2.alpha1.tar.gz.sig I wanted to start stabilizing v2.2 release some months ago already, but I somehow got stuck adding more and more features. Now it looks like all of the necessary API changes are done, so everything I'm planning on near future can still be added to v2.2 without major changes. The redesigned dsync hasn't had much testing yet, so avoid running it with important mails. Would be nice if people started testing and reporting any bugs. I was going to create some kind of a test suite for testing all the possible syncing combinations and also doing some random stress testing, but I haven't had time for that yet. The new dsync supports doing very fast syncs by saving the resulting state and giving it as command line parameter to the next sync. So for example doveadm sync -s "" > new-state saves the state and doveadm sync -s `cat new-state` continues from the saved state. The replicator code doesn't yet support this. * When creating home directories, the permissions are copied from the parent directory if it has setgid-bit set. For full details, see http://wiki2.dovecot.org/SharedMailboxes/Permissions * "doveadm auth" command was renamed to "doveadm auth test" * IMAP: ID command now advertises server name as Dovecot by default. It was already trivial to guess this from command replies. + Implemented IMAP MOVE and BINARY extensions + Implemented IMAP CATENATE, URLAUTH and URLAUTH=BINARY extensions (by Stephan Bosch). + Implemented IMAP NOTIFY extension. Requires mailbox_list_index=yes to be enabled. + Redesigned and rewritten dsync. The new design makes the syncing faster, more reliable and more featureful. The new dsync protocol isn't backwards compatible with old dsync versions (but is designed to be forwards compatible with future versions). + All mailbox formats now support per-user message flags for shared mailboxes by using a private index. It can be enabled by adding :INDEXPVT=<path> to mail location. This should be used instead of :INDEX also for Maildir/mbox to improve performance. + Improved mailbox list indexes. They should be usable now, although still disabled by default. + Added LAYOUT=index. The mailbox directories are created using their GUIDs in the filesystem, while the actual GUID <-> name mapping exists only in the index. + LMTP proxy: Implemented XCLIENT extension for passing remote IP address through proxy.

Re: [Dovecot] Android ICS stock client and IMAP Capability issue.
by Massimiliano Cianelli 08 Nov '12

Hi, Yes w/o prefix work as expected, try to add a prefix like courier does (eg. Inbox.) It will not work as expected. Due I'm upgrading an old installed server, I've to keep everything as much transparent I can... it includes IMAP folder and subscription. Looking at that I've encountered that issue, and analyzed for fix it (thank you open source), not everyone will want to use/use k9.. but you can be 100% sure the stock client is there. Due that Google act like BlackBerry, Microsoft,etc.. (hovewer they will not fix it soon, or really respect the rfc), it's much simple add Namespace on prelogin banner then wait or have to tell someone to install another client for that mailbox. I didn't know the history, but looking at change log seems that idle as been put back to prelogin client for some kind of compatibility with their service. Anyway, the most important reason that got me to subscribe the mailing list for write those emails, is share with the community that problem and provide a solution.. for someone in the future that have the same problem and will search on internet for a solution (like I've does.. before analyze it on my own). If the workaround will be added to the wiki or will be put in the source.. the important thing is that there is a solution simple and fast (two.. the source modify, and the configuration file) and someone can find it.. (Sarcastic) And if the mayans were right we can't wait for google to fix it :p Best Regards Sent from Galaxy Nexus Robert Schetterer <rs(a)sys4.de> ha scritto: >Am 07.11.2012 08:13, schrieb Massimiliano Cianelli: >> Hello, >> >> My phone: >> Android ics 4.1.2 on galaxy nexus. >> And yes, stock mean the default client that come with the os in IMAP mode. >> >> I already know about that configuration parameter, but it will display two time namespace in postlogin capabilities, and so I like much more to adjust the source code to fix the issue. >> >> Yes there is k9 but I didn't like it too much, I prefer the stock client and is much important to keep compatibility with stock client then user-installed client. >> >> About the issue on Google code, there is thr issue on google code... but Google is a lot slow in fixing those things. >> http://code.google.com/p/android/issues/detail?id=1811 >> >> In a few hour I'll update the issue noticing where is hidden the problem. >> >> Regards >> Sent from Galaxy Nexus > >Hi , i shortly tested this with android sdk jelly bean 4.1.1 and "my >setup" dovecot 2.1.10 with included orginal android mail app in imap mode, >,leaving IMAP prefix blank, everything works as expected, no double >shown inbox, namespace problems etc >so you might have to fit your namespace setup. >Also you might follow allready given advice from here. > >Anyway , i understand you using "stock client" >but you have to understand that the producers of mail clients >optimize their stuff fitting best in their own server structure >making money with it, therefor their motivation coding better imap code >is not very high, same case is for outlook and microsoft >however, i would say, fixing bugs is on the google site here, looks like >there is patch >at >http://code.google.com/p/android/issues/detail?id=1811 >and the issue seems long known > >i dont see any hard relation to dovecot in this case >meanwhile using k9mail seems the best way to workaround >there are lots of other bugs around android versions >over the years i dont expect google to fix them > > >> >> Robert Schetterer <rs(a)sys4.de> ha scritto: >> >>> Am 06.11.2012 07:08, schrieb Ben Morrow: >>>> At 6AM +0100 on 6/11/12 you (Massimiliano Cianelli) wrote: >>>>> Hi, >>>>> >>>>> My setup: >>>>> Dovecot 2 latest, installed to replace courrier IMAP, and off course >>>>> configured with the dot separator and all folder under INBOX.*. >>>>> >>>>> The problem: >>>>> My phone was driving me mad during the test, due that it will only >>>>> recognize Inbox. >>>>> >>>>> How found the solution: >>>>> I've started sniffing IMAP traffic on my server and ended up with one >>>>> difference: >>>>> On courier it ask for namespace, on dovecot it won't. >>>>> >>>>> I gives a better look, and noticed that courier show namespace >>>>> capability on prelogin banner, adding it too solved the problem. >>>>> >>>>> Reason: >>>>> Android ICS stock client seems do not honor the capability gived after >>>>> the login. >>>> >>>> See http://wiki2.dovecot.org/Upgrading/2.0?highlight=%28capability%29 ; >>>> you need to set imap_capability and/or get your client fixed. >>>> >>>> Ben >>>> >>> >>> Hi, first ,what is the exact meaning of >>> >>> "Android ICS stock client" >>> >>> do you mean default included email client in standard android in imap >>> mode, when yes, which version of Android , i like to test my own >>> however is there changelog/code etc at google for this behave? >>> >>> conf example >>> >>> # Override the IMAP CAPABILITY response.

[Dovecot] Auth USER lookup failed
by Angel L. Mateo 07 Nov '12

07 Nov '12

Hello, I'm running dovecot 2.1.9 and I'm trying to configure shared folders. So, as described at http://wiki2.dovecot.org/SharedMailboxes/Shared I have configured a namespace like this: namespace { type = shared separator = / prefix = shared/%%u/ location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u subscriptions = no list = yes } In one user (user1) I have configured ACLs so another one (user2) has access to a folder. Now, I want to susbscribe user2 to this folder. The problem I have is that whenever I try to list folders for this user (running thunderbird client) I get a panic and an error in the dovecot server (I have attached the complete log). The error says: Nov 6 11:58:56 myotis30 dovecot: auth: Error: userdb(user1): client doesn't have lookup permissions for this user: userdb uid (113246) doesn't match peer uid (14585) (change userdb socket permissions) Nov 6 11:58:56 myotis30 dovecot: auth: Debug: master out: FAIL#0112 Nov 6 11:58:56 myotis30 dovecot: imap(user2): Error: user user1: Auth USER lookup failed Nov 6 11:58:56 myotis30 dovecot: imap(user2): Debug: auth input: Nov 6 11:58:56 myotis30 dovecot: imap(user2): Error: Couldn't create namespace 'shared/' for user user1: userdb didn't return a home directory, but plugin setting quota used it (%h): dict:User quota::file:%h/Maildir/dovecot.quota It seems that imap process running for user2 is trying to a user lookup that fails. So I have manually tried it root@myotis30:/etc/dovecot/conf.d# sudo -u user2 doveadm user user2 userdb: user2 home : <homeDirectory> uid : 14585 gid : 404 root@myotis30:/etc/dovecot/conf.d# sudo -u user2 doveadm user user1 doveadm(user2): Error: user user1: Auth USER lookup failed doveadm(user2): Error: userdb lookup failed for user1 I have checked the socket permissions, but they are 0666 (if I'm looking the right socket): root@myotis30:/etc/dovecot/conf.d# ls -l /var/run/dovecot/auth-userdb srwxrwxrwx 1 dovecot root 0 nov 6 11:43 /var/run/dovecot/auth-userdb In fact, I have tried to put all sockets with permissions 0666 and 0777, but the error persists.

[Dovecot] LDAP congestion
by Bernhard Schmidt 07 Nov '12

07 Nov '12

Hello, I've been asked to have a look at a misbehaving mail server of some colleagues today where almost all logins where failing or excessively delayed, while the LDAP database itself was pretty fast. They run Dovecot 1.2.11 (yes, I know, stoneage) against an LDAP server run by a 3rd party, auth_bind=yes (required). The problem is that this third party LDAP server delays bindResponse 3 seconds when the password is wrong. A user wanted to login every 2-3 seconds this morning with the wrong password, which effectively killed the system because the LDAP connection was mostly stalled waiting for the auth timeout. >From a previous discussion with Timo I know that bindRequests cannot be parallelized in LDAP, so the problem does not come completely unexpected. Other than removing the failure delay in the LDAP server, is there anything one can do? If there is any change in newer Dovecot versions about that please tell me so I can encourage them to upgrade, but I haven't seen anything in the changelog. Any way to get several LDAP workers/connections for passdb in parallel? Thanks, Bernhard

[Dovecot] "starting" dovecot

My system never issues the "dovecot start" command. I do, however, run /usr/local/libexec/dovecot/imap on port 9xxx. I talk to the server through port 9xxx and through the preauth tunnel. Is this arrangement OK? Are there some things that will only work if "dovecot" is invoked?

[Dovecot] Modifying mailbox GUIDs?

Greetings all, I can view a mailbox's GUID like so: doveadm mailbox status -u guid However, how may I *modify* a mailbox GUID? Can this be done using doveadm or some other tool? If not, how may I go about modifying the dovecot.mailbox.log (where I assume GUID data is stored)? My specific use case has to do with me wanting to modify an existing mailbox's GUID so that its messages are mirrored into a folder of the same name using "dsync mirror". (As we know, dsync utilizes GUIDs to determine mailbox uniqueness) Thanks! -- - Faheem

[Dovecot] Error: Internal quota calculation error
by Micah Anderson 07 Nov '12

07 Nov '12

Hello, I'm using 2.1.7 with seive and mysql quotas. We had an outage the other day where the database server where quotas are stored was not available for a short period of time. In dovecot land, the following types of errors occured in that scenario: Oct 26 22:19:01 grosbeak dovecot: lda(example(a)riseup.net): Error: Internal quota calculation error Oct 26 22:19:01 grosbeak dovecot: lda(example(a)riseup.net): Error: sieve: msgid=<20122132765181x.ABCCE457(a)example.com>: failed to store into mailbox 'Trash': Internal error occurred. Refer to server log for more information. [2012-10-26 22:19:01] Oct 26 22:19:01 grosbeak dovecot: lda(example(a)riseup.net): Error: sieve: script /maildir/e/example/.dovecot.sieve failed with unsuccessful implicit keep (user logfile /maildir/e/example/.dovecot.sieve.log may reveal additional details) I expect that there would be quota calculation errors as dovecot could not reach the database server, but what worried me was the 'failed to store into mailbox' message from sieve. The 'Trash' mailbox in this particular seive script is the correct location for the message to be filed into, but the worrisome message is the 'failed with unsuccessful implicit keep'. I looked through all the message-ids that reported this error and I found that the messages were properly delivered in the end, so this might be some issue interacting between sieve, dovecot and quota and just causing a scary message that can be ignored? thanks for any information you can provide, dovecot is great! micah --

[Dovecot] how to best import Evolution/Thunderbird mail into dovecot?
by Christoph Anton Mitterer 07 Nov '12

07 Nov '12

Hi. I'm migrating all my mail archive (some 60 GB) from Evolution (which is really a broken piece of software) into dovecot. Now I face the problem how to do this best... Evolution (which is still a old 2.32.x version) itself uses mbox files, in a special hierarchical structure to allow subfolders and that like. It also stores it's own status info in X-Evolution and X-Evolution-Source mail headers. Unfortunately,... much of the mail was earlier from a Thunderbird installation, which uses it's own status headers (X-Mozilla*) that were not recognised by Evolution. I have no idea which mbox subformat was always used throughout the different programs and versions... 1) Any way to check for that? To make things worse... Thunder(burden) seems to have used a modified From_ line syntax... "^From -<address> <date>$" Ideally I'd like migrate all mail into dovecot (for storage reasons again, mbox) retaining the different status flags (read, forwarded, etc.) and getting rid of the proprietary headers (of course only when they were. First thing I tried was to simply copy mail within Evolution (i.e. dragging&dropping it from the local folders to the IMAP folders from dovecot). - that preserves the status from Evolution, but doesn't restore that from Thunderbird - it clutters up the information of all From_ lines... "<address> <date>" becomes "<address of my default evolution account> <now>" - neither does it handle the special Thunderbird From_ lines - neither does it remove the Thunderbird or the X-Evolution-Source headers - if Evolution has already had corrupted index files (and this is extremely likely... as it happens even immediately during recreating all of them)... so I may loose mail So my idea was that I need a program that: - can parse all the different mbox formats (those that use the quoted ">From" style and those that use Conent-Length) - can differentiate message headers from body (so that I can drop the proprietary headers and replace them by what dovecot uses as headers) - must of course understand multiline message headers 2) Any idea for a tool like that? The meaning of the X-Evolution and X-Mozilla* headers are easy to find on the web.... so I can convert them. So I basically "just" need a tool that parses all kinds of mbox formats... allow me to drop/add headers... and spits out the rest unmodified. 3) dovecot uses some special headers like X-UID and X-IMAPD... will it create these on it's own, the first time it processes the new mbox file? I mean these headers won't be there after creation. 4) Should I drop out (during) conversion... any other mail headers.. that dovecot uses as it's own? Thanks, Chris.

Hello, My phone: Android ics 4.1.2 on galaxy nexus. And yes, stock mean the default client that come with the os in IMAP mode. I already know about that configuration parameter, but it will display two time namespace in postlogin capabilities, and so I like much more to adjust the source code to fix the issue. Yes there is k9 but I didn't like it too much, I prefer the stock client and is much important to keep compatibility with stock client then user-installed client.

[Dovecot] sieve
by Christian Rößner 06 Nov '12

06 Nov '12

Hi, is there a sieve option that can reject a mail directly without creating a new mail and sending that out? I know about reject "Reject message goes here"; but I am looking for a mechanism that can reject Mail. Postfix can use reject_unverified_recipient to connect to LMTP and ask if a mail would successfully be enqueued and will return the status gotten from the LMTP server if not. Chances are high that the mechanism would work, too, if Dovecot would know about the sieve rule, while getting a connection on LMTP. Does Dovecot know all rules at this point or is sieve handled after the mail has already been accepted?

[Dovecot] Android ICS stock client and IMAP Capability issue.
by Massimiliano Cianelli 06 Nov '12

06 Nov '12

Hi, My setup: Dovecot 2 latest, installed to replace courrier IMAP, and off course configured with the dot separator and all folder under INBOX.*. The problem: My phone was driving me mad during the test, due that it will only recognize Inbox. How found the solution: I've started sniffing IMAP traffic on my server and ended up with one difference: On courier it ask for namespace, on dovecot it won't. I gives a better look, and noticed that courier show namespace capability on prelogin banner, adding it too solved the problem. Reason: Android ICS stock client seems do not honor the capability gived after the login. Request: Maybe is possible to put namespace capability in prelogin banner for the next version? That will solve trouble with a setup like the mine and android stock email client. Thank you, Best regards Sent from Galaxy Nexus

[Dovecot] Quota
by Christian Rößner 05 Nov '12

05 Nov '12

Hi, is it possible to ask Dovecot for a users quota by talking to the Dovecot server over TCP? I know about doveadm quota -u <user>, but I would like to know, if I can query for that over a network connection (on the Postfix ML they suggested writing a policy service that checks quota. Postfix is not always on the same server as Dovecot is). Does the LMTP protocol give that information somehow? I am not so familiar with LMTP. Or some Unix-Socket to query that could also be configured as inet_listener?

Hi. Even new mails delivered by my MDA don't get the ,S= and ,W= fields set... (but when I "upload" a mail via IMAP to dovecot, they are set) Is there some place in dovecot where I need to enable this? Or would it be the MDA that has to calculate and set this already when placing a file in ./new? Thanks, Chris.

I don't know if Dovecot takes advantage of this in any way though. Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] dovecot dimensioning
by mancyborg＠gmail.com 01 Nov '12

01 Nov '12

Hi All, first post here, nice to meet you :) I've been using dovecot + postfix + clamav + spamassassin for years but always with few users. Now i must build a server for 1500 users, they will use various email software (thunderbird, outlook, ..) the webmail (i'm not sure if squirrelmail or roundcube) and blackberry devices (with the BIS service). There will be around 1000 domains (virtual_domains) and postfix will read its users and domains from mysql. Let's say that they will send and receive around 5000 emails per hour (10K in total per hour). I was thinking to use karspersky server instead of clamav. I already have the hardware, it is a server with 4 physical cpu (Intel Xeon E5504 @ 2.00GHz) and 24 gb of ram, do you think it is enough ? Thanks for supporting, regards and have a nice day, Mike
