[Dovecot] ACLs - creating new top level folders
by Ingo Rogalsky 22 May '13

22 May '13

Hi, I'm wondering, whether it's possible, to define an ACL on the mailbox itself. We use Dovecot 1.2.15 (included in Debian 6) and maildir filesystem layout: /home/mail01/user1/Maildir/new \ /home/mail01/user1/Maildir/cur Inbox /home/mail01/user1/Maildir/tmp / /home/mail01/user1/Maildir/.folder1/new \ /home/mail01/user1/Maildir/.folder1/cur folder1 /home/mail01/user1/Maildir/.folder1/tmp / ... Assigning an ACL with full access rights for user2 to the folder Inbox works as expected. user2 can create subfolders of Inbox, too. But he can't create a new folder like folder1 parallel to Inbox. Is there a possibility of defining an ACL on the mailbox of user1 itself? Or do we need to create all subfolders beneath Inbox like this is usual with other IMAP servers?

[Dovecot] dsync-2.2.2 incorrectly synchronizes subscription status of deleted mailbox
by Karol Jurak 22 May '13

22 May '13

Hi, It seems that dsync-2.2.2 doesn't correctly synchronize subscription status of a deleted mailbox. The situation is as follows. There are two servers: A and B, and a test user test_mdbox. Mailboxes (mdbox) of this user on both servers are synchronized. Specifically on both of them there is a Trash/x mailbox. Replication plugin is disabled. I delete Thrash/x mailbox on A with Thunderbird. The relevant IMAP commands issued are: 71 87.068176 10.4.0.13 10.1.107.144 IMAP Request: 9 delete "Trash/x" 72 87.072238 10.1.107.144 10.4.0.13 IMAP Response: 9 OK Delete completed. 73 87.073736 10.4.0.13 10.1.107.144 IMAP Request: 10 unsubscribe "Trash/x" 74 87.085263 10.1.107.144 10.4.0.13 IMAP Response: 10 OK Unsubscribe completed. Inspecting output of 'doveadm mailbox list' and contents of subscriptions file shows that everything is as expected, ie. mailbox was deleted and unsubscribed. Moreover in dovecot.mailbox.log on A the following records appear: #480: delete-mailbox 3f3eb117a51c9a51d8280000f671379f (2013-05-20 14:54:40) #504: delete-dir f91e44cab57821aa456b525c7a2f1d7e (2013-05-20 14:54:40) #528: unsubscribe f91e44cab57821aa456b525c7a2f1d7e (2013-05-20 14:54:40) Subsequently I run 'doveadm sync -u test_mdbox -d'. It causes an entry for Thrash/x to reappear in subscriptions file on both servers and the following records are appended to dovecot.mailbox.log on B: #2112: delete-mailbox 3f3eb117a51c9a51d8280000f671379f (2013-05-20 14:55:49) #2136: delete-dir f91e44cab57821aa456b525c7a2f1d7e (2013-05-20 14:55:49) On A this record is added: #552: subscribe f91e44cab57821aa456b525c7a2f1d7e (2013-05-20 14:55:49) So, in described situation, dsync subscribes a mailbox on a server it was deleted on instead of unsubscribing it on the other one. -- Karol Jurak

[Dovecot] Dovecot 2.2.1 LDA and sieve (lack of) errors
by Jim McNamara 22 May '13

22 May '13

Hello again, all. Of course after posting yesterday that all was well with my setup, turns out all is not well. The problem I'm having is with dovecot-lda functioning and making deliveries to my mailbox, but the sieve scripts don't seem to have any effect. Attempts at logging what is/isn't happening have been total failures. Managesieve seems to work fine, port 4190 is open on the server and it allows the tunderbird plugin to function, I can create and edit scripts with the plugin. For some reason it doesn't seem to auto-compile the scripts to binary form, but if I just need to do that manually I can live with it. I only mention the lack of auto-compiling in case that sheds light on what is wrong with the LDA or sieve. I'm running the current dovecot, 2.2.1 along with pigeonhole 0.4.0. Here is the config: root@hostname:/usr/local/dovecot-2.2.1# doveconf -n # 2.2.1: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 3.2.0-4-amd64 x86_64 Debian 7.0 auth_cache_size = 10 M auth_default_realm = mail.domain.com auth_mechanisms = plain login auth_socket_path = /usr/local/var/run/dovecot/auth-userdb debug_log_path = /dev/stderr default_internal_user = vpopmail default_login_user = vpopmail first_valid_gid = 89 first_valid_uid = 89 hostname = mail.domain.com last_valid_gid = 89 last_valid_uid = 89 lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes log_path = /dev/stderr mail_access_groups = 89 mail_debug = yes mail_gid = 89 mail_location = maildir:%h/Maildir mail_plugins = " quota" mail_privileged_group = 89 mail_uid = 89 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 spamtest spamtestplus vnd.dovecot.debug namespace inbox { inbox = yes location = prefix = separator = . } passdb { driver = vpopmail } plugin { quota = maildir:User quota quota_rule = *:storage=2G quota_warning = storage=95%% quota-warning 95 %u sieve = ~/.sieve/dovecot.sieve sieve_dir = ~/.sieve sieve_extensions = +spamtest +spamtestplus +relational +comparator-i;ascii-numeric +vnd.dovecot.debug } postmaster_address = postmaster(a)mail.domain.com protocols = imap pop3 lmtp sieve sendmail_path = /var/qmail/bin/sendmail service auth-worker { user = $default_internal_user } service auth { unix_listener auth-userdb { group = vchkpw mode = 0600 user = vpopmail } user = $default_internal_user } service managesieve-login { inet_listener sieve { port = 4190 } service_count = 1 vsz_limit = 64 M } ssl = required ssl_cert = </var/qmail/control/servercert.pem ssl_key = </var/qmail/control/servercert.priv userdb { args = quota_template=quota_rule=*:backend=%q driver = vpopmail } protocol lda { info_log_path = /dev/stderr log_path = /dev/stderr mail_plugins = " quota sieve" } protocol imap { mail_plugins = " quota imap_quota" } protocol pop3 { mail_plugins = " quota quota" } I've set the lda specific logs to /dev/stderr because I'm running dovecot through daemontools, and that is what it logs.

Re: [Dovecot] Outlook 2013 - mounting folders with XLIST
by Hajo Locke 21 May '13

21 May '13

Hello, >> i do some tests with dovecot 2.1.7 and activated a default special-use >> config. To get it work with outlook 2013, i also added XLIST to imap >> capability string. basically this is working. >> >> is somebody also using special-use folders successful with outlook 2013? > yes, testet a few times, works fine, without Junk folder , cause > outlook wants this handled by it own, but i ve seen reg patches to > change this My serverside setup now is completed. I did a lot of tests last weeks and experienced some strange behaviour of some clients. Outlook 2013 is only working when adding XLIST manually to imap_capability imap_capability = +XLIST This is because outlook 2013 not supports rfc 6154 but the deprecated XLIST standard invented by google. So the problem with junkfolder is not a bug in Outlook 2013, in rfc 6154 spamfolder is tagged by \Junk, in XLIST standard \Spam is used. I did see that when using a gmailaccount in outlook 2013. Adding XLIST capability to dovecot seems to be a problem for other Clients. k9 is able to work with rfc 6154 servers. But if k9 finds XLIST and SPECIAL-USE together in capabilitystring it seems to prefer XLIST requests. Because of dovecot is accepting XLIST requests, but outputs rfc 6154 details, k9 seems to be confused and dont finds special Folders. rfc 6154 is similar but not identical to XLIST. If you dont test with really individual foldernames, you get tricked by clients behaviour. I looked around and the most imap-servers of hosting companies etc. provide XLIST feature, Special-USE unfortunately only a few. So i did now some changes to dovecot sources on my own. I added \Spam as allowed special-use attribute and created a new function for XLIST Requests. So if XLIST is requested, Clients gets lines of output with XLIST and \Junk is replaced with \Spam. So all is done in the code and i dont need to change my userdb-config. Testing this server with different clients was successful. All of them did find their special folders and worked fine, outlook 2013 also finds spamfolder now. So this changes contribute to consolidate a deprecated standard but i have to find a way where all users can benefit from new features. This is not a request to change something in dovecot, this is a call to decision makers to support one rfc Standard. Hajo

[Dovecot] Configure dovecot to provide SASL authentication
by Peter Skensved 21 May '13

21 May '13

Hi, I'm trying to get dovecot to provide SASL authentication for postfix My setup appears to be working but I'm not 100% certain I've got it right. I've come across several examples for dovecot version 1 but I'm running 2.0.9. The output of doveconf -n is here : 2.0.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-279.2.1.el6.x86_64 x86_64 CentOS release 6.3 (Final) auth_debug = yes auth_verbose = yes disable_plaintext_auth = no mbox_write_locks = fcntl passdb { driver = pam } protocols = imap service auth { unix_listener /var/spool/postfix/private/auth { mode = 0666 } } ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { driver = passwd } Specifically : are the "service auth", userdb and passdb sections correct ? And the mode ? Or is it too permissive ? For completeness the postfix setup is here : smtpd_sasl_auth_enable = yes broken_sasl_auth_clients = yes smtpd_sasl_type = dovecot smtpd_sasl_path = private/auth smtpd_sasl_security_options = noanonymous # smtpd_delay_reject = yes smtpd_helo_required = yes smtpd_helo_restrictions = permit_mynetworks, reject_non_fqdn_helo_hostname, reject_invalid_helo_hostname, permit # smtpd_sender_restrictions = permit_mynetworks, reject_non_fqdn_sender, reject_unknown_sender_domain, permit # smtpd_recipient_restrictions = reject_unauth_pipelining, reject_non_fqdn_recipient, reject_unknown_recipient_domain, permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination, permit # peter ---- Peter Skensved Dept. of Physics, Queen's University, Kingston, Ontario, Canada

[Dovecot] How to configure ssl cert chain in dovecot 10-ssl.conf file

Hi there, Does anyone know how to do this: "Put all the certificates in the ssl_cert file. For example when using a certificate signed by TDC the correct order is: Dovecot's public certificate TDC SSL Server CA TDC Internet Root CA Globalsign Partners CA " I try to set these parameters in the conf.d/10-ssl.conf as below, but it seems doesn't work. --- ssl_cert = </etc/pki/dovecot/certs/mail.mymailserver.com.crt ssl_cert = </etc/ssl/certs/dovecot/sub.class1.server.ca.pem ssl_cert = </etc/ssl/certs/dovecot/ca.pem ---- I even cat mail.mymailserver.com.crt sub.class1.server.ca.pem certs/dovecot/ca.pem into one singe file, and define ssl_cert = < /path/to/the/singcertfile.pem, but it doesn't work too. In my apache httpd server httpd.conf file I can define: -- SSLCertificateChainFile /etc/pki/dovecot/certs/sub.class1.server.ca.pem SSLCACertificateFile /etc/pki/dovecot/certs/ca.pem -- And it well work fine.

[Dovecot] v2.2.2 + dsync version incompatibility

Looks like dsync v2.2.2 isn't fully compatible with earlier dsync versions, unless you add: http://hg.dovecot.org/dovecot-2.2/rev/e0156c479a12

[Dovecot] Linking mdbox directories
by Alex Crow 20 May '13

20 May '13

Hi Timo/list, We have a scenario in which some email accounts on dovecot (stored in mdbox, separate paths for indexes, email, ALT storage and also using SIS for attachments, LDAP directory) need their names changed. I know we could just change the mail LDAP attribute (and leave mailMessageStore alone) so they keep the same directories on disk, but this would throw a spanner in the works for our backups. Would it be possible to create a hard link of the user's directories under the new name, and change the LDAP mailMessageStore attribute to point to these without stopping and starting dovecot? And after a while unlink the original locations? Or would this mess up dovecot's internal state?

Hi, im wondering if it's possible to store old messages in a compressed mdbox on alternate storage. The main storage is uncompressed mdbox. I tried something like: doveadm -Dv -o "plugin/zlib_save=gz" altmove -u testuser sentbefore 8d Could someone tell me if it's possible and give me a hint how this can be done?

[Dovecot] Empty file in maildirs
by Roel Wagenaar 20 May '13

20 May '13

I am cleaning up some old users, and found that in every maildir folder there is an empty file called maildirfolder, created at the time the original dovecot was installed. Is this empty file necessary for dovecot, or is it left there in an upgrade proces and can it be removed?

[Dovecot] v2.2.2 released
by Timo Sirainen 20 May '13

20 May '13

http://dovecot.org/releases/2.2/dovecot-2.2.2.tar.gz http://dovecot.org/releases/2.2/dovecot-2.2.2.tar.gz.sig It's been a while since v2.2.1. I think all of the bad bugs in v2.2 series should be fixed by now, so here's a new release. I think there are still some small URLAUTH bugs left though, so you might want to wait before enabling it in production (imap_urlauth_host is empty by default, which disables it). + zlib: Keep the last mail cached uncompressed in a temp file. This fixes performance when doing small partial fetches from a large mail. + acl: If plugin { acl_defaults_from_inbox = yes } is set, get the default ACLs for private and shared namespaces from the user's INBOX. (This probably will become default in v2.3.) + pop3: Added pop3_deleted_flag setting to switch POP3 deletions to only hide the messages from POP3, but still be visible via IMAP. - ACL plugin: Mailbox creation wasn't actually checking any ACLs and always succeeded (due to some v2.2 API changes). The created mailbox couldn't have been accessed though, so this couldn't have caused any data leak. - IMAP: Various URLAUTH fixes. - IMAP: Fixed a hang with invalid APPEND parameters. - IMAP LIST-EXTENDED: INBOX was never listed with \Subscribed flag. - mailbox_list_index=yes still caused crashes. - maildir: Fixed a crash after dovecot-keywords file was re-read. - maildir: If files had reappeared unexpectedly to a Maildir, they were ignored until index files were deleted. - Maildir: Fixed handling over 26 keywords in a mailbox. - Maildir++: Fixed mail_shared_explicit_inbox=no - namespace { prefix="" list=no } was listing mailboxes. - imap/pop3-login proxying: Fixed a crash if TCP connection succeeded, but the remote login timed out. - Case-insensitive search/sort didn't work correctly for all unicode characters, as specified by i;unicode-casemap comparator. If full text search indexes were used, they need to be rebuilt for old mails to be handled correctly. (This bug has existed always in Dovecot.)

[Dovecot] Quota not working with dict proxy
by Chris Richards 16 May '13

16 May '13

Hello all, I'm sure this has been covered somewhere before, but my googlefu is not up to the challenge. Basically, I'm trying to configure quota plugin to use a dictionary service (specifically proxy with mysql) so that I can store the quota usage in a database and use that information in a lookup for postfix to reject mail if over quota. I'm doing this because postfix+avamis+dovecot setup with amavis re-injecting into postfix results in mail being effectively accepted before dovecot lmtp knows if mailbox is full. I'm currently using quota maildir: quota = maildir:User quota and this works; doveadm -Df tab quota get -u 'user@domain' Quota name Type Value Limit % User quota STORAGE 55388 204800 27 User quota MESSAGE 4883 - 0 When I use quota dict: quota = dict:User quota:%u:proxy::quota I get this: "doveadm -f tab quota get -u user@domain" Quota name Type Value Limit % User quota STORAGE 0 204800 0 User quota MESSAGE 0 - 0 So far so good. But manually setting database entry to values retrieved above with maildir quota results in this: Quota name Type Value Limit % User quota STORAGE 54 204800 0 User quota MESSAGE 4883 - 0 I'm guessing this is returning values in KB, so that makes sense, I guess. Attempting to recalc quota on one account using command: "doveadm -f tab quota recalc -u user@domain" returns with nothing, and when I repeat 'quota get' command, it says: doveadm(user@domain): Fatal: User doesn't exist Err............what?! Indeed, looking in the database shows the account in question was actually DELETED! Obviously, I've got something messed here, but I don't know what. I need some guidance here. Dovecot version is 2.1.12 Here is my config: # 2.1.12: /etc/dovecot/dovecot.conf # OS: Linux 3.7.5-hardened-r1 x86_64 Gentoo Base System release 2.1 ext4 auth_master_user_separator = * auth_mechanisms = plain login auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@& auth_verbose_passwords = plain default_process_limit = 200 dict { quota = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } disable_plaintext_auth = no login_greeting = Awaiting command... mail_location = maildir:/home/vmail/%d/%n/Maildir mail_plugins = " quota" mail_privileged_group = 100 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 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 = INBOX. separator = . type = private } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { expire = Trash 7 expire2 = Trash/* 7 expire3 = Spam 7 quota = dict:User quota:%u:proxy::quota quota_rule = *:storage=200M quota_warning = storage=99%% quota-warning 99 %n %d quota_warning2 = storage=95%% quota-warning 95 %n %d quota_warning3 = storage=80%% quota-warning 80 %n %d quota_warning4 = -storage=95%% quota-warning 'less than 95' %n %d sieve = ~/.dovecot.sieve sieve_default = /home/vmail/dovecot/sieve/default.sieve sieve_dir = ~/sieve sieve_global_dir = /home/vmail/dovecot/sieve } protocols = imap pop3 sieve lmtp service auth-worker { user = $default_internal_user } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } unix_listener auth-userdb { group = dovecot mode = 0666 user = dovecot } user = $default_internal_user } service dict { unix_listener dict { mode = 0600 user = vmail } } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } } service quota-warning { executable = script /etc/dovecot/quota-warning.sh unix_listener quota-warning { user = vmail } user = dovecot } ssl_cert = </etc/ssl/dovecot/server.pem ssl_key = </etc/ssl/dovecot/server.key userdb { driver = prefetch } userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } protocol lmtp { mail_plugins = sieve quota postmaster_address = postmaster@domain } protocol lda { mail_plugins = " quota sieve quota" } protocol imap { mail_max_userip_connections = 20 mail_plugins = " quota quota imap_quota" } protocol pop3 { mail_plugins = " quota quota" } >From dovecot-dict-sql.conf.ext: connect = host=localhost dbname=maildb user=dbuser password=dbpass # CREATE TABLE quota ( # username varchar(100) not null, # bytes bigint not null default 0, # messages integer not null default 0, # primary key (username) # ); map { pattern = priv/quota/storage table = email username_field = address value_field = quota_bytes } map { pattern = priv/quota/messages table = email username_field = address value_field = quota_messages } # CREATE TABLE expires ( # username varchar(100) not null, # mailbox varchar(255) not null, # expire_stamp integer not null, # primary key (username, mailbox) # ); map { pattern = shared/expire/$user/$mailbox table = email value_field = expire_stamp fields { address = $user maildir = $mailbox } } Other than some guesswork, I've not got the FOGGIEST idea what the settings in the file actually mean; it doesn't seem to be documented anywhere. Also, the quota plugin settings, at least with respect to using a proxy service, don't seem to be real explanatory either, e.g. the reason I'm using %u for the user is because I stumbled across a post suggesting that leaving it blank would result in just getting the username instead of the username@domain. This is not at all obvious from the documentation, IMO. The docs would benefit greatly from some example use cases (no, I'm not volunteering; I'm TERRIBLE with documentation ;) ). Anyway, if someone could proffer some help or at least guidance here, I'd be very grateful.

[Dovecot] dovecot 2.2.0 corrupts mailboxes?
by manu＠netbsd.org 16 May '13

16 May '13

Hi On april 17th, I upgraded from dovecot 2.1.13 to 2.2.0. Since that time, I had two different users that reported received three incident of messages that disapeared from their mailboxes. The mailbox format is mbox on local FFS filesystem (no NFS), and I use filesystem quotas (but both users are far from filling their quotas). When the message disapeared, it was always a whole rand of dates. On the last incident reported, the user also saw some message being duplicated many times. There is something interesting in the logs: May 4 20:16:30 volanges dovecot: imap(jdoe): Error: Cached message size smaller than expected (2000 < 8063) May 4 20:16:30 volanges dovecot: imap(jdoe): Error: Corrupted index cache file /mail/indexes/jdoe/.imap/INBOX/dovecot.index.cache: Broken physical size for mail UID 141869 May 4 20:19:48 volanges dovecot: imap(jdoe): Error: Cached message size smaller than expected (9711 < 16248) May 4 20:19:48 volanges dovecot: imap(jdoe): Error: Corrupted index cache file /mail/indexes/jdoe/mail/.imap/Arxiv/dovecot.index.cache: Broken physical size for mail UID 4383 May 4 21:14:35 volanges dovecot: imap(jdoe): Error: Cached message size smaller than expected (1878 < 8066) May 4 21:14:35 volanges dovecot: imap(jdoe): Error: Corrupted index cache file /mail/indexes/jdoe/mail/.imap/CNRS/dovecot.index.cache: Broken physical size for mail UID 290 May 4 21:15:17 volanges dovecot: imap(jdoe): Error: Cached message size smaller than expected (17285 < 24440) May 4 21:15:17 volanges dovecot: imap(jdoe): Error: Corrupted index cache file /mail/indexes/jdoe/mail/.imap/Commandes/dovecot.index.cache: Broken physical size for mail UID 680 Does that ring a bell?

[Dovecot] quota with imapc

Dear dovecot team, I have set up my mail system with a mail gateway connecting to mail server using imapc. Now I need my web mail client to show up the quota info.

Is there any way the plugin will get quota info from the mail server? I am attaching my conf ## Dovecot configuration file in mail_uid = imapproxy mail_gid = imapproxy mail_home = /home/imapproxy/%u mail_location = imapc:~/imapc protocols = imap ## ## imapc settings ## imapc_host = mailserver.example.com imapc_port = 143 imapc_ssl = starttls imapc_ssl_ca_dir = /etc/postfix/certs ## ## auth settings ## auth_mechanisms = plain login passdb { driver = imap args = host=mailserver.example.com ssl=starttls ssl_ca_dir=/etc/postfix/certs default_fields = userdb_imapc_user=%u userdb_imapc_password=%w ssl=starttls } userdb { driver = prefetch } mail_plugins = $mail_plugins quota plugin { quota = maildir:User quota quota_rule = *:storage=200M } protocol imap { # Space separated list of plugins to load (default is global mail_plugins). mail_plugins = $mail_plugins imap_quota } ## ## SSL settings ## ssl = required disable_plaintext_auth = yes #verbose_ssl = yes ssl_cert = </etc/postfix/certs/public_cert.pem ssl_key = </etc/postfix/certs/private_key.pem ssl_cipher_list = ALL:!LOW:!SSLv2:!EXP:!aNULL Greetings. -- View this message in context: http://dovecot.2317879.n4.nabble.com/quota-with-imapc-tp42280.html Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] Looking for a good way to manage passwords for CRAM-MD5
by Steinar Bang 15 May '13

15 May '13

I prefer not to use clear text passwords, even over an encrypted connection. With IMAP, the only such mechanism with widespread client support is CRAM-MD5 (please correct my if I'm wrong... I'd love to be corrected here...). On the dovecot 2 wiki, the only way I've found to implement CRAM-MD5 support, is to use a passwd-like file: http://wiki2.dovecot.org/HowTo/CRAM-MD5 I am running a small IMAP server used by my family. As long as I was the single user on the IMAPd, manually managing the passwd file as doable (if a bit cumbersome). With 2-5 users, I'm looking for a more elegant solution. Does anyone have a similar situation, and a solution they would like to share (config/HOWTO)? Here are the possibilities that comes to mind: 1. Create a web interface to change the password (does anyone know of a ready-made solution for this that they could recommend?) 2. Convince PAM to update the dovecot HMAC-MD5 password file as well as the regular system password file (my dovecot runs on a debian stable "wheezy" system. In theory this should be possible, but it is very hard to find documentation on what PAM modules exist, and how to write a new one, and if it is possible to chain modules in PAM, ie. use one module to update-this-passwd-file and then use a different module to update a different passwd file) 3. Use LDAP, which I think can also support CRAM-MD5 when using password lookups http://wiki2.dovecot.org/AuthDatabase/LDAP/PasswordLookups (learning how to set up LDAP is something I have avoided for years, because it looks awfully complex and time consuming) I haven't looked into using databases, SQL, or key-value store, because they seem like a more cumbersome way to do the same thing as passwd files. But I am aware that this assumption could be wrong. It could e.g. be easier to make the web interface idea work with a database manager, than messing around with setuid bits to safely update a passwd file owned and touchable only by the dovecot user. Thanks for any and all responses! - Steinar

[Dovecot] dovecot 2.0 -> 2.1 sieve problem
by Trever L. Adams 15 May '13

15 May '13

I had a completely working setup before. I upgraded, now I get: Error: 7LUaNYqHklG6EAAApwKjnA: sieve: execution of script (null) failed, but implicit keep was successful sieve = /home/vmail/%Ld/%Ln/.dovecot.sieve sieve_dir = /home/vmail/%Ld/%Ln/sieve (this was ~/sieve) I am not quite sure what is going on. Is anyone else seeing this? Any idea on what has changed? (I am not readily seeing it in changelogs or mailing lists.)

[Dovecot] 2.2.1 and quota-status
by Christian Rößner 15 May '13

15 May '13

Hi, maybe this question already came up and I missed it in my mails, but if not… : I have configured Quota for Dovecot since decades and now with the new policy service, I wanted to include this into Postfix. I have followed Ralf's Blog and there a two Problems: I need to do this: ls -la /var/run/dovecot/config srw------- 1 root root 0 May 14 11:06 /var/run/dovecot/config chown vmail /var/run/dovecot/config ls -la /var/run/dovecot/config srw------- 1 vmail root 0 May 14 11:06 /var/run/dovecot/config Where can I tell Dovecot to set user vmail here? If I do not do this, I get the following error in the logs: May 14 10:54:50 mx0 dovecot: quota-status(c(a)roessner-network-solutions.com): Error: user c(a)roessner-network-solutions.com: Error reading configuration: net_connect_unix(/var/run/dovecot/config) failed: Permission denied Also the following test does not succeed: telnet localhost 12340 Trying ::1...

[Dovecot] Crossrealm Kerberos problems
by Jonathan Hanks 15 May '13

15 May '13

I am running dovecot 2.1.7 on Debian Squeeze 64 bit, config information at the end of the email. I am working on a Kerberos/GSSAPI based setup that requires cross-realm authentication. I have regular GSSAPI working, I can log in using pam_krb5 with password based logins or with the GSSAPI support when using a kerberos ticket in the default realm. However when I attempt to authenticate using cross realm authentication the login fails (logs below). After perusing the source code I beleive that the problem is as such: All taking place in mech-gssapi.c 1. mech_gssapi_userok(...) calls mech_gssapi_krb5_userok 2. mech_gssapi_krb5_userok(...) calls krb5_kuserok(...) to verify that the given Kerberos prinicpal can log in as the requested user. 3. The authentication process is running as the Dovecot user so: 3a. krb5_kuserok(...) looks for ~dovecot/.k5login to authorize cross realm logins 3b. There is no ~dovecot/.k5login, thus no cross realm access is allowed 3c. It should be looking at the users .k5login ~poptest/.k5login 3d. This never happens and the login attempt fails I have the server set up to use system users specifically so that I can do cross-realm authentication. Do I have some basic configuration error? How do I change the authentication process to run as the user requesting to login? Should that be allowed? Another thought is to backport some of the patches proposed for 2.2 that remove krb5_kuserok from the loop. Thank you for any insight. This server is not in production use so I can experiment.

[Dovecot] Fatal: Can't finish POP3 UIDL command
by stevenfah 15 May '13

15 May '13

I have been setting up a new mail server and copied our client's old mail to it. The old server has Courier (under Plesk), we're using Dovecot on the new server. Most accounts seem to work fine (under IMAP or POP3), but for a few we're getting the following in the /var/log/mail.err. Error: Message ordering changed unexpectedly (msg #1: storage seq 140 -> 1) Fatal: Can't finish POP3 UIDL command And the affected accounts can't get at their email. Things work ok if people switch to IMAP but for some of our clients that is a difficulty, so we really need POP3 working. I used the Perl script given here to convert the mailboxes. The only fix we've found is the rename/delete the Dovecot-uidlist file for the affected mailboxes and we've done that, as it was only a few. The issue now is that more mailboxes are coming with the same error, even though they were fine originally. -- View this message in context: http://dovecot.2317879.n4.nabble.com/Fatal-Can-t-finish-POP3-UIDL-command-t… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] Lucene and Zlib with 2.2.1
by Kyle Wheeler 15 May '13

15 May '13

Hello, I have an "archive" folder in my inbox, where I manually stick old mails into a compressed mbox format. Since upgrading to Dovecot 2.2.1, I've started seeing messages like the following in my log files: imap(...): Error: lucene: Failed to sync mailbox INBOX: Mailbox isn't selectable indexer-worker(...): Error: lucene: Failed to sync mailbox INBOX: Mailbox isn't selectable indexer-worker(...): Error: lucene: Failed to sync mailbox INBOX: Mailbox isn't selectable indexer-worker(...): Error: lucene: Failed to sync mailbox INBOX: Mailbox isn't selectable imap(...): Error: indexer failed to index mailbox INBOX/Archive/2007/Sent.gz These errors *appear* to be mostly benign; I still get results from searching the mailbox. But for whatever reason, the indexer appears to not be working for those folders. As you can probably tell, I'm using the fts_lucene plugin, which used to work just fine (with Dovecot 2.1.x). Is this expected behavior? Are these errors truly ignorable? Why are these compressed mailboxes not selectable? ~Kyle -- Where justice is denied, where poverty is enforced, where ignorance prevails, and where any one class is made to feel that society is an organized conspiracy to oppress, rob and degrade them, neither persons nor property will be safe. -- Frederick Douglas

[Dovecot] protocols and privileges
by andreas graeper 15 May '13

15 May '13

hi, 1) protocols = pop3 but when starting the service, output tells about imap. when mua fetches mails ~/mail/.imap/INDEX is created. 2) i have some users uid=500 .. 505. src in /var/mail/%u, owner is <user>.mail and home-directories /home/<user> - owner is <user>.users when dovecot tries to create directory /home/<user>/mail then it tells for user xyz (uid = 502) euid=502(xyz) egid=100(users) missing +w permission /home/xyz , euid is not dir owner. but /home/xyz is owned by xyz.users and mod = 0700 ( drwx------ ) same environment for uid = 501 works great ! thanks in advance andreas ? permission lookup from /home/xyz/mail failed do i have to create that mail directory manually ?

[Dovecot] dovecot 2.2.1: lmtp running in base_dir
by Andy R 15 May '13

15 May '13

Evening all, I'm running into an issue with lmtp trying to store user mail in 'base_dir' ( same as this ( http://www.dovecot.org/list/dovecot/2011-January/056736.html )) however I'm just using PAM for auth. I've tried with chroot, without chroot and 'chroot'ing lmtp directly in ' service lmtp { } ' which just lead to lots more errors. I've not included anything of the current config so far, as I don't know what is needed here yet. I'm sure I'm missing something obvious, but I can't spot it for the life of me. Can anyone offer any new ideas? Many thanks Andy R.

Hi there, I am using Evolution to connect to dovecot imap server. Today the server was upgraded to 2.2.1 from 2.1.9, and there is problem with evolution being unable to subscribe to INBOX. This is from dovecot 2.1.9: a002 list "" "*" return (subscribed) * LIST (\Subscribed) "." "Sent Items" * LIST (\Subscribed) "." "Junk E-mail" * LIST (\Subscribed) "." "Trash" * LIST (\Subscribed) "." "Archive" * LIST (\Subscribed) "." "Drafts" * LIST (\Subscribed) "." "INBOX" <--- And this is from 2.2.1: a002 list "" "*" return (subscribed) * LIST (\Subscribed) "."

[Dovecot] IMAP SSL proxy (questions)
by Trever L. Adams 15 May '13

15 May '13

Hello everyone, I have seen: http://wiki.dovecot.org/HowTo/ImapProxy. It doesn't seem to fit what I need. Unfortunately, I cannot use TLS. I have to use SSL. Also, I would rather not duplicate the certificates for the IMAP servers. Hence nginx doesn't seem to be a good choice either. I am hoping that since SSL has "Client Hello" which specifies the site requested the the following could be done: Client - > Proxy [SYN] Proxy -> Client [SYN, ACK] Client -> Proxy [ACK] Client -> Proxy [SSL With "Client Hello", having server_name in Extension: server_name and sub-fields] Proxy sees intended host Proxy <-> Intended Server [SYN/SYN+ACK/ACK sequence] Proxy -> Intended Server [Replay SSL/Client Hello] Client <-> Proxy <-> Intended Server (Proxy is non decrypting Man-in-the-Middle, just acting as a pseudo-invisible relay) I know that something somewhat like this works because this is how Apache can do virtual hosts with SSL. Of course, it acts as the end point intended server, not a proxy. I believe it is also somewhat how Squid does SSL proxying, although I could be entirely wrong. Is this possible? Can this be implemented in dovecot? If not, does anyone know of such a project. Proxy needs to not have any exploitable holes and really only needs to understand enough SSL to get the server_name, pass through the connection, replaying Client Hello, and then knowing when to shut the connection. Just as a breif example, the use I have for this now is that I have several imap servers which all have IPv6 addresses, but have to share an IPv4 address. for SMTP side of things, this works well for all incoming email. (As an aside, does anyone know of a similar setup for SSL traffic on port 465 SSL for SMTP?) Thank you for any help, Trever

[Dovecot] Keyword limit?
by Michael M Slusarz 15 May '13

15 May '13

Running into a weird issue in a mailbox that has 26+ keywords. In one session, I do this: S: 2 SELECT "INBOX" (QRESYNC (1255685337 78608 [...uids...])) S: [...] S: * OK [HIGHESTMODSEQ 78608] Highest S: * OK [UIDVALIDITY 1255685337] UIDs valid S: 2 OK [READ-WRITE] Select completed. C: 3 UID STORE 48386 (UNCHANGEDSINCE 78608) +FLAGS AAAAAAAA S: * 8 FETCH (UID 48386 MODSEQ (78609) FLAGS (\Seen AAAAAAAA)) S: 3 OK Store completed. C: 4 LOGOUT S: * OK [CLOSED] Previous mailbox closed. S: * BYE LOGOUT received S: 4 OK Completed The next time I access that mailbox, I see this: C: 2 SELECT "INBOX" (QRESYNC (1255685337 78609 [...uids...])) S: [...] S: * OK [UIDVALIDITY 1255685337] UIDs valid S: * OK [HIGHESTMODSEQ 78609] Highest S: * 8 FETCH (MODSEQ (78610) UID 48386 FLAGS (\Seen)) S: 2 OK [READ-WRITE] Select completed. MODSEQ 78610 is entirely server-initiated. It *appears* that the mailbox doesn't handle more than 26 keywords. My dovecot-keywords looks like: 0 $Forwarded [Entries 1-24] 25 Test "Test" is a keyword I created immediately before "AAAAAAAA". If I remove Test and then add "AAAAAAAA", the keyword sticks. Is this a built-in limit? Can't find anything in the config/wiki docs (Dovecot 2.1.16). Or are my dovecot index/cache files hosed in some way? michael

[Dovecot] Mail deduplication
by Tim Groeneveld 15 May '13

15 May '13

Hi Guys, I am wondering about mail deduplication. I am looking into the possibility of seperating out all of the message bodies with multiple parts inside mail that is recived from `dovecot` and hashing them all. The idea is that by hashing all of the parts inside the email, I will be able to ensure that each part of the email will only be saved once. This means that attachments & common parts of the body will only be saved once inside the storage. How achievable would this be with the current state of dovecot? Would it even be worth doing? Thanks, Tim

[Dovecot] quota and dict
by Jeff Gustafson 15 May '13

15 May '13

I have a question about using dict and quotas. I want dovecot to send quota queries to a custom dict server over a socket. I'm doing this because I can't do group quotas based on domain since a customer can have each of their users associated with different domains under a single account. I need to lookup the account ID and group based on that. I'm worried putting everything in mysql will cause way too many writes and lower the performance of our mysql cluster. I have having a little trouble connecting all the dots in the config file. In the userdb example, there is an 'args' parameter that allows a file to specify a uri. I don't see how to do that for dict. I only see file, mysql, and postgresql. Shouldn't I be able to use a dictionary proxy to attach any custom program to a quota dict socket? Tell the quota plug to proxy quota which then points to a socket: plugin { quota = dict:User quota::proxy::quota } dict { quota = proxy:/tmp/test-socket } or should it be: plugin { quota = dict:User quota::proxy:/tmp/test-socket } Neither one create a socket in /tmp. It seems like this should be possible, but I don't see an obvious way to do it. ...Jeff

[Dovecot] Released Pigeonhole v0.4.0 for Dovecot v2.2.1.
by Stephan Bosch 15 May '13

15 May '13

Hello Dovecot users, I finally release the first version of Pigeonhole v0.4 for Dovecot v2.2. The main reason for the delay was that some unexpected (design) problems occurred with the new doveadm-sieve plugin, which allows synchronizing sieve scripts using doveadm sync. One important change is that I incorporated the extprograms plugin into the main Pigeonhole release. With this plugin it is possible to execute administrator-controlled external programs (shell scripts) from the Sieve interpreter, e.g. for special message delivery, filtering and string manipulation. The list of new features is not that impressive. I've been working on IMAP URLAUTH, IMAP CATENATE and HTTP support for Dovecot. Currently, I'm building an SMTP submission proxy server. After all that I plan to spend more time on Sieve development. One of the most important issues on my list is implementing support for using alternative types of storage (e.g. a database) for Sieve scripts, rather than only a filesystem directory as it is now. Changelog v0.4.0: + Added doveadm-sieve plugin that provides the possibility to sync Sieve scripts using doveadm sync along with the user's mailboxes. + Added the Sieve extprograms plugin to the main Pigeonhole package. It is still a plugin, but it is now included so that a separate compile is no longer necessary and distributors are likely to include it. The extprograms plugin provides Sieve language extensions that allows executing (administrator-controlled) external programs for message delivery, message filtering and string manipulation. Refer to doc/plugins/sieve_extprograms.txt for more information. + Added debug message showing Pigeonhole version at initialization. Makes it very clear that the plugin is properly loaded. + Finished implementation of the Sieve include extension. It should now fully conform to RFC 6609. The main addition is the new :optional tag which makes the include command ignore missing included scripts without an error. + Finished implementation of the Sieve environment extension as much as possible. Environment items "location", "phase" and "domain" now also return a usable value. The release is available as follows: http://www.rename-it.nl/dovecot/2.2/dovecot-2.2-pigeonhole-0.4.0.tar.gz http://www.rename-it.nl/dovecot/2.2/dovecot-2.2-pigeonhole-0.4.0.tar.gz.sig Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information. Have fun testing this new release and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

15 May '13

List, good evening, just installed a new Debian Stable (Wheezy). The Debian Stable repositories now include Dovecot 2.1.7 as standard. I haven't installed that because I wanted to try 2.2.x on this new clean install but unsure which 'pool' to use in the xi.rename-it.nl repository of autobuilds. http://xi.rename-it.nl/debian/pool/ Wheezy became Stable on May 5, just a few days ago. I'm not sure whether to still follow the advice in the wiki for obtaining 2.2.x for Wheezy, which (understandably, because the new Debian Stable release has been so very recent) continues to refer to Wheezy as 'testing'. http://wiki2.dovecot.org/PrebuiltBinaries#Automatically_Built_Packages Presumably, the packages in the 'testing' autobuild system pick up Debian's 'testing' pool libraries (or assume them to exist) and these may no longer be the ones needed for Wheezy because Wheezy is 'Stable', in Debian-speak. Does anyone know, for sure, which autobuild pool to now use for 2.2.x for Wheezy? http://xi.rename-it.nl/debian/pool/stable-auto/ or http://xi.rename-it.nl/debian/pool/testing-auto/ 2.2.x in 'stable-auto' doesn't seem to have changed since before Wheezy was released, whereas 2.2.x has changed in 'testing-auto', and I'm not sure what to make of that. Stephan does suggest that queries be directly written to him, but I posted here because I thought I might not be the only person who was unsure. I'd be grateful for any advice, regards, Ron

[Dovecot] Idea: POP3 deletion as a flag
by Timo Sirainen 14 May '13

14 May '13

GMail doesn't delete mails when POP3 client issues a DELE command for it. Instead they just become invisible for future POP3 sessions, but they still exist for IMAP/webmail. The same could be implemented pretty easily for Dovecot: - Add a new setting to enable this: pop3_deleted_flag = $POP3Deleted - When DELEting a message, add this flag to the message. - When listing messages, skip all messages that have this flag. - Also hide this flag from IMAP clients(?) Thoughts? Probably 20 lines of new code.

I have Doveot 2.1.1 on Centos, all's well user mails are kept for 60 days, then, 'aged off' (deleted) a Mac user with two domains and two dozen users asked me: can I set a mail server on my home Mac server, and, 'mirror' the real mail server mailboxes so than I can have an offline mail archive for ever ? I know very little about Macs, can I setup dovceot on Mac? any tips/suggestions/howtos for mirroring/archiving as so?

[Dovecot] Any way to let dovecot block pop3 attempts?
by Steve Campbell 12 May '13

12 May '13

Is there a way using dovecot facilities to block an IP from attempting POP3 connections (similar to the sendmail access file for smtp connections)? I usually do this at my border firewall, but if there's a quick and dirty way in dovecot to do this, it'd make life a little simpler. Thanks steve campbell

Re: [Dovecot] change inbox dotlock name
by Chris Saldanha 10 May '13

Axel Luttgens <AxelLuttgens(a)swing.be> wrote: > But I fear I don't understand your problem description. > Could you elaborate? Hi Axel, The issue is that the procmail port on FreeBSD doesn't acquire a dotlock when it's the default lock file (/var/mail/username.lock). It prints that it's bypassing the dotlock and just does a lockf() lock after. Looking in the code for procmail, it seems that it's being too clever with a bunch of checks and so it doesn't try to get the lock -- it's decided it doesn't want to before doing it. The permissions and runtime environment permit the lock, and the same lock is acquired correctly by dovecot when writing to the inbox. I'm doing dotlock and then lockf() locking in all the mail software. procmail's checks only seem to apply to the default lock file for the inbox. If I specify an alternate name in the .procmailrc for the $ORGMAIL delivery of the message, then it will acquire any other lock I ask, including an alternate name in the /var/mail directory. I'll dig into the procmail sources as needed to resolve it, but I had hoped that I could get dovecot to lock with a different filename, because that would resolve the issue with minimal hackery...
