by Balamurugan Ramasamy 10 Mar '14

10 Mar '14

Hi All I follwed the steps in the below url to configure a dovecot proxy instance. http://wiki2.dovecot.org/PasswordDatabase/ExtraFields/Proxy I created a new file '95-test.conf' in /etc/dovecot/conf.d/ location. and put the below lines in that file. proxy=yes host=**** port=143 nopassword=yes However I am getting the following when starting the serice. I tried 'proxy' and 'proxy_maybe' entries, and they both failed. doveconf: Fatal: Error in configuration file /etc/dovecot/conf.d/10-auth.conf line 11: Unknown setting: proxy Could anyone help me how i can resolve this? Thanks Bala

[Dovecot] Sieve/autosubscribe subfolder
by Moritz Augsburger 08 Mar '14

08 Mar '14

Hi, I just ran across the annoying issue, that with lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes set, parent folders of newly created subfolders get subscribed without being existent. Let me give an example: In sieve I use fileinto "foo/bar"; but "foo/" does not exist as folder. So the Mailbox "foo/bar" gets created, but without "foo/" being a Mailbox. Nevertheless gets "foo/" subscribed, so that I have a non-existing mailbox in my subscription list, what confuses thunderbird. So, to solve this problem, I would propose - either the implicit creation of foo/ as mailbox or - not subscribing foo/ Moritz

[Dovecot] Mbox corruption - Inbox beginning with 'FFrom' or 'FrFrom'
by Dimos Alevizos 08 Mar '14

08 Mar '14

Hello, we're having some problems with our dovecot setup. I've seen similar problems in the mailing list some years ago but alas wasn't able to find a solution. Our setup is as follows : An MX farm (postfix) sends mails via LMTP to a director farm (dovecot 2.1.12) which proxies pop3/imap/lmtp traffic to a dovecot farm (dovecot 2.1.16). All mailboxes and indexes are on NFS and all servers are Centos. The problem is that at times we see mailboxes (all of them are in mbox format) beginning with FFrom or FrFrom and of course dovecot says it's not a valid mbox file. If we manually remove the offending extra characters from the beginning of the file everything is working again, but often the same user will show the problem again tomorrow. However it's very rare and so far we haven't been able to reproduce the problem. After activating the mail_log plugin hoping it'll help us locate the problem we run across this case : The user (let's call him user(a)domain.gr) logs in via pop3 and deletes some mails but one of them fails: Jun 19 11:09:18 pop01 dovecot: pop3-login: Login: user=<user(a)domain.gr>, method=PLAIN, rip=83.235.173.26, lip=83.235.66.40, mpid=1389, secured, session=<Ao+rWH3fHgBT660a> Jun 19 11:09:18 director5 dovecot: pop3-login: proxy(user(a)domain.gr): started proxying to 83.235.66.40:110: user=<user(a)domain.gr>, method=PLAIN, rip=83.235.173.26, lip=83.235.66.65, session=<Ao+rWH3fHgBT660a> Jun 19 11:09:24 pop01 dovecot: pop3(user(a)domain.gr): expunge: box=INBOX, uid=20670, msgid=<9f5b1a20a9428ed31a9e7e42ce4411f08d0.20130612070424(a)mail84.us2.rsgsv.net>, size=36526 Jun 19 11:09:24 pop01 dovecot: pop3(user(a)domain.gr): expunge: box=INBOX, uid=20671, msgid=<b27d72dc5a47a3235a232494c6fe8aa0(a)newsletter.stockout.gr>, size=4637 Jun 19 11:09:24 pop01 dovecot: pop3(user(a)domain.gr): expunge: box=INBOX, uid=20672, msgid=<1113670779560.1111910791405.1470.2.32032003(a)scheduler.constantcontact.com>, size=38655 Jun 19 11:09:24 pop01 dovecot: pop3(user(a)domain.gr): expunge: box=INBOX, uid=20673, msgid=<83600a274c1407c5aa4c263e2592cb54(a)debop.gr>, size=1181688 Jun 19 11:09:24 pop01 dovecot: pop3(user(a)domain.gr): expunge: box=INBOX, uid=20674, msgid=<F2A59BE7-007A-4567-9BA5-803446C3D7F8(a)bernier-eliades.gr>, size=61116 Jun 19 11:09:26 pop01 dovecot: pop3(user(a)domain.gr): Error: Next message unexpectedly corrupted in mbox file /var/mail/K/Y/V/domain_gr_user_007 at 1 Jun 19 11:09:26 pop01 dovecot: pop3(user(a)domain.gr): Error: Cached message offset 1 is invalid for mbox file /var/mail/K/Y/V/domain_gr_user_007 Jun 19 11:09:27 pop01 dovecot: pop3(user(a)domain.gr): Disconnected: Logged out top=0/0, retr=2/1502843, del=122/359, size=137448432 Jun 19 11:09:27 pop01 dovecot: pop3(user(a)domain.gr): Warning: Our dotlock file /var/mail/K/Y/V/domain_gr_user_007.lock was deleted (locked 9 secs ago, touched 9 secs ago) Jun 19 11:09:27 pop01 dovecot: pop3(user(a)domain.gr): Error: file_dotlock_delete() failed with mbox file /var/mail/K/Y/V/domain_gr_user_007: No such file or directory Jun 19 11:09:27 director5 dovecot: pop3-login: proxy(user(a)domain.gr): disconnecting 83.235.173.26 (Disconnected by server): user=<user(a)domain.gr>, method=PLAIN, rip=83.235.173.26, lip=83.235.66.65, session=<Ao+rWH3fHgBT660a> However he's still able to log in again : Jun 19 11:11:36 pop01 dovecot: pop3-login: Login: user=<user(a)domain.gr>, method=PLAIN, rip=85.74.231.10, lip=83.235.66.40, mpid=10094, secured, session=<QDLrYH3f7ABVSucK> Jun 19 11:11:36 director3 dovecot: pop3-login: proxy(user(a)domain.gr): started proxying to 83.235.66.40:110: user=<user(a)domain.gr>, method=PLAIN, rip=85.74.231.10, lip=83.235.66.63, session=<QDLrYH3f7ABVSucK> Jun 19 11:11:51 pop01 dovecot: pop3(user(a)domain.gr): Disconnected: Logged out top=0/0, retr=0/0, del=0/237, size=75036938 Jun 19 11:11:51 director3 dovecot: pop3-login: proxy(user(a)domain.gr): disconnecting 85.74.231.10 (Disconnected by server): user=<user(a)domain.gr>, method=PLAIN, rip=85.74.231.10, lip=83.235.66.63, session=<QDLrYH3f7ABVSucK> A few minutes later he receives another mail which is delivered with no problem : Jun 19 11:30:39 corvus amavis[546]: (00546-22) Passed CLEAN, [91.190.168.40] [91.190.168.40] <tk-14439(a)free.splio.com> -> <user(a)domain.gr>, Message-ID: <58175-bWFyaW5hQGJlcm5pZXItZWxpYWR lcy5ncg==(a)free.splio.com>, mail_id: J1P-0WpmQksJ, Hits: 1.412, size: 9025, queued_as: 02BA4AE00414, Tests: [DKIM_VALID=-0.1,DKIM_VERIFIED=-0.1,FREEMAIL_FROM=0.001,HTML_IMAGE_RATIO_04=0.61,INVALID_MSGID=1,URIBL_BLOCKED=0.001], autolearn=disabled, 1533 ms Jun 19 11:30:39 corvus smtp/smtpd[1283]: proxy-accept: END-OF-MESSAGE: 250 2.0.0 from MTA(smtp:[127.0.0.1]:10025): 250 2.0.0 Ok: queued as 02BA4AE00414;

[Dovecot] Planning migration
by Alan Chandler 08 Mar '14

08 Mar '14

I think I have a working dovecot installation, and the time has come to migrate my users. There are only 4 of us, so it can be done manually per user. I looked at this page in the wiki http://wiki2.dovecot.org/Migration/Dsync but I am totally confused. 1st off, it uses doveadm, but with commands parameters that dont match my doveadm's man page. In fact they look more like dsync parameters. Is there an error, or am I totally misunderstanding 2nd - if I assume its a dsync set of parameters, the imapc: at the end is a specification of location2. However, again my man page doesn't give any explanation of this. I am wondering, is this an example of an proxy 3rd - where do the imapc_* parameters go in the configuration I can't find any reference to them in the wiki

[Dovecot] How to run a program with mail_filter plugin
by Stanislas SABATIER 07 Mar '14

Hi, I'm using mail_filter plugin but I don't want it to launch a script but a program I wrote instead. In 10-master, if I put the absolute path to my program in the plugin settings ie : (…) service mail-filter { executable = /usr/local/bin/mail/my_email_filter (…) But I've got the following error from Dovecot : dovecot: master: Error: service(mail-filter): Initial status notification not received in 30 seconds, killing the process h ow do I need to configure the service to launch my program ?

[Dovecot] no sieve with lmtp_save_to_detail_mailbox=yes
by Dennis Kuhn 06 Mar '14

06 Mar '14

i have a problem with sieve and lmtp_save_to_detail_mailbox = yes. If the mailbox "detail" exists everything works fine, but if the mailbox detail does not exist then sieve does not work. The .dovecot.sieve.log file says sieve: info: started log at Mar 06 14:28:47. error: msgid=<531877EE.7070806(a)heinlein-support.de>: failed to store into mailbox 'test2': Mailbox doesn't exist: test2. I think this is the reason why no sieve script is executed, but why is sieve here involved? Is there any relation between lmtp_save_to_detail_mailbox=yes and sieve or is this a bug? The same sieve file works with the same mailaddress without mailextension, so the sieve script is not the reason for the failure. I am using dovecot version 2.2.12 Dennis Kuhn -- Heinlein Support GmbH Schwedter Str. 8/9b, 10119 Berlin http://www.heinlein-support.de Tel: 030 / 405051-57 Fax: 030 / 405051-19 Zwangsangaben lt. §35a GmbHG: HRB 93818 B / Amtsgericht Berlin-Charlottenburg, Geschäftsführer: Peer Heinlein -- Sitz: Berlin

[Dovecot] Still no emails since Feb. 6
by Steve Campbell 06 Mar '14

06 Mar '14

I checked my settings on the dovecot mailman page, and although my account was set to "disable" email, after changing it and attempting to have the list resend my password, I'm still not seeing emails. The last time I received emails, the outgoing server for the list was sent from the IP 193.210.130.67. Is that still correct? I've checked my logs to see if there's anything blocked, and I don't see anything. I've checked my access file and firewall, and nothing is blocked there. I'm not sure why my account settings showed "disabled", but it sounds like email was either bounced back to the list or my server is in some type of outgoing list to prevent sending to me. I'm at a loss. Is there any way an admin can check for me, please, to see if there's a problem they might spot? Thanks, steve

[Dovecot] Pigeonhole Sieve Extprograms Plugin

Hi, I upgraded to Dovecot 2.2.9 from Debian's wheezy-backports today (which should contain the "sieve_extprograms" plugin and thus also the vnd.dovecot.{pipe,filter,execute} capabilities. However when I add require "vnd.dovecot.filter"; to my sieve script via managesieve, the server reports error: require command: unknown Sieve capability: 'vnd.dovecot.filter' What am I missing and what should I do to get pipe/filter/execute to work? postconf -n attached.

[Dovecot] whole user mailbox read only
by Francesco 06 Mar '14

06 Mar '14

Hello, i was browsing the dovecot wiki for some documentation related to the use of ACLs but i couldn't find an answer. i'm in the need to prevent users from deleting emails, yet being able to add new content via imap, what i mean is that a user should be able to create an email in its mailbox (maildir actually is used), but once the email is there the user shouldn't be able to delete it. do you know if there is a way to accomplish this for each subfolder on a Maildir environment? Thanks in advance Francesco

[Dovecot] Shared Namespace and correct location
by Dieter Knopf 05 Mar '14

05 Mar '14

Hello again, i still have problems using a Shared Namespace in my configuration. I'm using Dovecot 2.2.9. mail_location = maildir:/home/vmail/%d/%n/MAILDIR:INDEX=/home/vmail/%d/%n/INDEX/ namespace inbox { type = private separator = / prefix = inbox = yes } This works create. But: namespace { type = shared separator = / prefix = shared/%%u/ location = maildir:/home/vmail/%%d/%%u/MAILDIR/shared:INDEX=/home/vmail/%d/%u/INDEXS/%%u subscriptions = no list = children } I'm still not sure how i can see a shared mailbox on a different account. I can add ACL rules and dovecot is adding SQL-Entries to the user-shares table. The dovecot-acl-list file is created too, hope this is okay (vfile + SQL) But i can't see the shared folder on the target account. I tried many location-pathes, but not sure how i can add the right folder. There must be a problem with %%d and %%u. Thank you very much, Dieter

[Dovecot] Dovecot Migration: Retrieving/Logging POP/IMAP Passwords in Plaintext
by Traiano Welcome 05 Mar '14

05 Mar '14

Hi List I'm currently in the process of migrating my dovecot imap/pop users to a new server and have to extract their passwords in order to import them into the new system (different password encryption schemes). I've tried enabling auth_* debug parameters in my dovecot.conf in the hope that this would result in logging plaintext passwords to the dovecot log. However dovecot does not log the passwords in plaintext under any debugging configuration. My question: Is there any other configuration of dovecot that would allow me to capture POP/IMAP passwords at a successful login time? Dovecot version: 1.0.7 (from dovecot-1.0.7-7.el5_7.1 rpm) The output of dovecot -n is: --- # 1.0.7: /etc/dovecot.conf info_log_path: /var/log/dovecot.debug verbose_ssl: yes login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login mail_location: mbox:~:INBOX=~/Mailbox mail_debug: yes mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/lib64/dovecot/imap mail_plugin_dir(imap): /usr/lib64/dovecot/imap mail_plugin_dir(pop3): /usr/lib64/dovecot/pop3 auth default: mechanisms: plain login verbose: yes debug: yes debug_passwords: yes passdb: driver: pam userdb: driver: passwd socket: type: listen client: path: /var/run/dovecot/auth-client mode: 438 --- My dovecot.conf is as follows: ------ info_log_path = /var/log/dovecot.debug verbose_ssl = yes mail_location = mbox:~:INBOX=~/Mailbox mail_debug = yes protocol imap { } protocol pop3 { } protocol lda { postmaster_address = postmaster(a)example.com } auth_verbose = yes auth_debug = yes auth_debug_passwords = yes auth default { mechanisms = plain login passdb pam { } userdb passwd { } user = root socket listen { client { path = /var/run/dovecot/auth-client mode = 0666 } } } dict { } plugin { } --- Many thanks in advance!

[Dovecot] Using AD, one more try - "successfol auth" and crashing auth process
by Jeroen Scheerder 05 Mar '14

05 Mar '14

Hi, I have no success in using AD with dovecot. The little checkpassword script I cooked up that uses ldapsearch to lookup a user DN (with an authenticated bind) and then ldapsearch with an authenticated bind for that DN again works well. * Approach 1: use a service account to bind to AD, lookup the user DN, and bind to that DN. It fails. The LDAP config looks like: hosts = dc2.office.on2it.net ldap_version = 3 base = dc=office,dc=on2it,dc=net scope=subtree auth_bind = yes dn = CN=DovecotSvc,OU=Svcs,DC=office,DC=on2it,DC=net dnpass = suppressed pass_attrs = sAMAccountName=user pass_filter = (&(objectClass=person)(sAMAccountName=%u)) user_attrs = sAMAccountName=user user_filter = (&(objectClass=person)(sAMAccountName=%u)) What happens in this case is best shown in the packet capture as displayed by tshark: $ tshark -o tcp.check_checksum:FALSE -tr -r dc2.pcap 1 0.000000 172.17.50.13 -> 172.17.10.2 LDAP 197 bindRequest(7) "CN=DovecotSvc,OU=Svcs,DC=office,DC=on2it,DC=net" simple 2 0.001879 172.17.10.2 -> 172.17.50.13 LDAP 88 bindResponse(7) success Yay! The service account binds just fine. 3 0.001967 172.17.50.13 -> 172.17.10.2 LDAP 180 searchRequest(8) "dc=office,dc=on2it,dc=net" wholeSubtree 4 0.002772 172.17.10.2 -> 172.17.50.13 LDAP 502 searchResEntry(8) "CN=Jeroen Scheerder,OU=Users,DC=office,DC=on2it,DC=net" \ | searchResRef(8) | searchResRef(8) | searchResRef(8) | searchResDone(8) success 5 0.098367 172.17.50.13 -> 172.17.10.2 TCP 66 49416 > 389 [ACK] Seq=246 Ack=459 Win=1037 Len=0 TSval=602425599 TSecr=124473537 Yay!

The user DN bind works. But wait, why is it taking dovecot 225 seconds to get around to trying it? The auth process has already given up. * Approach 2: A template defines the user DN. Bind to that DN. AD DNs don't contain usernames, but AD allows all kinds of non-LDAP shorthands for DNs, inclusing %user%@domain. I've verified this to work using ldapsearch: $ ldapsearch -o ldif-wrap=no -x -LLL -E pr=200/noprompt -H ldap://dc2.office.on2it.net \ -b dc=office,dc=on2it,dc=net -s sub \ -D js(a)office.on2it.net -W \ '(&(ObjectClass=person)(sAMAccountName=js))' DN Enter LDAP Password: dn: CN=Jeroen Scheerder,DC=office,DC=on2it,DC=net The config looks like: hosts = dc2.office.on2it.net ldap_version = 3 base = dc=office,dc=on2it,dc=net scope=subtree auth_bind = yes auth_bind_userdn = "%u(a)office.on2it.net" pass_attrs = sAMAccountName=user user_attrs = sAMAccountName=user What happens in this case is best shown by a snippet of dovecot logging: Mar 5 09:57:36 <mail.err> ponyboy dovecot: auth: Error: ldap(js,127.0.0.1,<z1dLNtjzJwB/AAAB>): ldap_search(base=dc=office,dc=on2it,dc=net filter=(&(objectClass=posixAccount)(uid=js))) failed: Operations error Mar 5 09:57:36 <mail.err> ponyboy dovecot: imap: Error: Disconnected from auth server, aborting (client-pid=7247 client-id=1) Mar 5 09:57:36 <mail.crit> ponyboy dovecot: auth: Fatal: master: service(auth): child 7245 killed with signal 11 (core not dumped - set service auth { drop_priv_before_exec=yes }) Mar 5 09:57:36 <mail.info> ponyboy dovecot: imap-login: Internal login failure (pid=7247 id=1) (internal failure, 1 successful auths): user=<js>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=7248, secured, session=<z1dLNtjzJwB/AAAB> I find this intriguing -- "1 successful auths", so says imap-login, with auth dying horribly. I smell a rat. Something's wrong here...

[Dovecot] Send and Bounced mail not appearing, depending on mail client
by Dominique 05 Mar '14

05 Mar '14

Hi, I just installed Dovecot2 on Ubuntu 12.04 server with postfix and postfixadmin. I am using virtual users and virutal domains. When using Thunderbird, Roundcubemail,iOS mail application on an iPad2 or Kmail n Android, all mail sent and bounce shows up. However, when using vTigerCRM to send mails, nothing shows up - anywhere. I know the mail are being send - as per the mail.log and the various postfix log lines. But none of that is being captured by Dovecot... What am I missing? Thanks for any hints you can provide.

This does not test what you want, which is trying to authenticate the master user, not the regular user. From what I remember of your config, you have another passdb which holds the credentials of your master user: you need to check that file to make sure the master user's password (hash) matches what you think the master password ought to be.

[Dovecot] Hidden virtual folder
by Moritz Augsburger 04 Mar '14

04 Mar '14

Hi, I wanted to create a virtual folder containing all unread messages and the threads they belong to, and this config works really fine: > dovecot.conf: namespace { type = private prefix = virtual/ separator = / location = virtual:~/Maildir/virtual:INDEX=MEMORY list = children subscriptions = no } > virtual/All/dovecot-virtual: * -Trash -Trash/* -Junk -Junk/* -Drafts -Drafts/* -virtual -virtual/* all > virtual/New/dovecot-virtual: virtual/All inthread refs or unseen recent The only problem I got is that scanning all files for the virtual/All mailbox takes too long, and I would like to keep them cached (no INDEX=MEMORY), so I thought I'll just put virtual/All inside a second virtual namespace. As it's a bad idea to open the All directory manually, I could also hide the complete namespace to the user. So I added the following to my config: namespace { type = private prefix = virtual-all/ separator = / location = virtual:~/Maildir/virtual-all/ hidden = yes list = no subscriptions = no } But sadly it didn't work, a directory virtual-all/ pops up inside my client (thunderbird/icedove). Is hidden=yes/list=no unsupported for virtual locations, or is it me misconfiguring dovecot? If it should matter, it's version 2.2.9, or more specific debian 1:2.2.9-1~bpo70+1. Thanks Moritz

Hi, I did the upgrade frpom 1.2.x to 2.2.10 and had some warnings/errors on a very few accounts/mailboxes. All of them where permission related and solved. Dovecot rocks again. But on one mailbox I do get an error: Error: user rechnnugseingang-animationsinstitut: Initialization failed: Initializing mail storage from mail_location setting failed Error: Invalid user settings. Refer to server log for more information. There is a homedirectory and the permissions are set like on all other accounts.

[Dovecot] Dovecot, AD and authenticated binds...
by Jeroen Scheerder 03 Mar '14

03 Mar '14

I posted earlier with reports of less than stellar success in using Active Directory for dovecot authentication. My approach is to using the two-step approach of - obtaining the user DN by a search using an authenticated bind (using a service account) - then binding as that DN, and returning the relevant user attributes This hasn't been succesful. Dovecot's authentication process does perform the (first) authenticated bind successfully, it does obtain the right DN, than just sits there doing nothing as far as I can tell, and after a long delay concludes authentication failure - shortly before deciding to perform the bind with the user-supplied credentials, successfully. Source inspection has not resulted in a glorious eureka yet. So I thought, why not handle it myself? And I wrote a little script, using the checkpassword interface. I've enclosed it. The script is based on <http://wiki2.dovecot.org/AuthDatabase/CheckPassword>, but somehow the userdb_uid and userdb_gid I've passed back in the "EXTRA" environment variable get lost along the way.

[Dovecot] Tracking logins
by Alex 03 Mar '14

03 Mar '14

Hi, I'm using dovecot-2.1.17 on fc18 and wondered if there is some mechanism, perhaps a database, that can store the logins/logouts for each user? I realize there's something already logged to syslog, but I'd like more of a history. While lastlog is great for users that actually login, my dovecot users don't login, just check email via pop and imap. Any ideas greatly appreciated. Thanks, Alex

[Dovecot] maildir quota divergence
by Juan Carlos Sanchez 03 Mar '14

Hello; We are using maildir quotas and have found differences in many users in respect to what system command are showing and doveadm quotas. For example, four user test, we have: doveadm quota get -u test Quota name Type Value Limit % STORAGE 98066 102400 95 MESSAGE 883 - 0 But if we check user mail_location with "du" system command we get he is using 70458 Kb. We are running dovecot 2.1.17 ¿any clue? Thanks in advance.

[Dovecot] No speed improvement with FTS for iOS 7?
by Nicholas Riley 02 Mar '14

02 Mar '14

Hi, I recompiled Dovecot with Lucene FTS to try to improve iOS 7 IMAP search speed. Unfortunately this does not seem to help. I have 60 mailboxes, totaling 300 MB; lucene-indexes is 30 MB in size. % doveadm mailbox status -t all '*' messages=16335 recent=0 unseen=1736 vsize=280049586 Searching for a single word which is present in two messages of one mailbox takes 40 seconds to return. This is true whether or not fts is enabled. doveadm search takes much less than 1 second to do the same search. % time doveadm search BODY cython d8f09230c97af952b60c0000c1443b93 1 d8f09230c97af952b60c0000c1443b93 2 doveadm search BODY cython 0.18s user 0.05s system 99% cpu 0.230 total With fts disabled, it takes about 6.5 seconds. This is still a long way from 40 seconds. Is there any way I can make dovecot perform better here? Thanks, -- Nicholas Riley <njriley(a)illinois.edu>

[Dovecot] + prefix in dovecot-virtual
by Nicholas Riley 01 Mar '14

01 Mar '14

Hi, The "+" prefix in dovecot-virtual does not seem to be documented. only discovered it because I tried to include a mailbox whose name began with + and Dovecot gave me an error when I tried to copy to it. I see it was added here: http://hg.dovecot.org/dovecot-2.2/rev/be0f0de75e34 My dovecot-virtual file looked like this: !+/2014-03 +/2014-02 all I just added another + to the second line and it seems to work. I don't care about \Recent thankfully but is there a better way to specify a mailbox whose name begins with +? Thanks. -- Nicholas Riley <njriley(a)illinois.edu>

[Dovecot] Force SSL authentication per user basis
by Urban Loesch 28 Feb '14

28 Feb '14

Hi, I'm searching a way to force encrypted connections for POP3/IMAP on a per user basis. To not break clients which still connect in plaintext (there are still many of it) I must implement a mechanism to force encrypted connections on a per user basis. The users and passwords are stored in a mysql database. So there would be no problem to expand the database with a column like "ssl_tls" -> yes/no. The problem now: how can I get dovecot to process this field in the right way? I searched the list and googled about such a way, but I can't find any solution. My Dovecot version is 2.2.12. Many thanks and regards Urban Loesch

[Dovecot] Logging authentication failures when Dovecot's auth service used to authenticate postfix smtpd
by MV 28 Feb '14

28 Feb '14

Hello, tl;dr: Is there a way to get dovecot's auth to log failed smtp authentications without having to switch on "auth_verbose"? postfix version 2.11.0 and dovecot version 2.2.12 I'm currently migrating my postfix+courier to postfix+dovecot and so far it's working as expected. Except for logging smtp login failures. Despite Postfix logging successful authentications (see sample below), it doesn't log failed smtp logins. Feb 25 22:28:53 mailer2 postfix/submission[20274]: C981B20198: client=A-B-C-D.*****.net[A.B.C.D]:63107, sasl_method=PLAIN, sasl_username=joe(a)example.net And since my postfix setup authenticates virtual users through Dovecot's auth, I thought maybe dovecot could report smtp login failures the same way it reports imap and pop3 login failures. Below is a sample extracted from "info_log_path" after several imap and pop3 login failures. (Obviously the IP 255.... is made up and irrelevant for this mater). # begin extract "/var/log/dovecot-info.log" 2014-02-27 21:14:26 auth: Info: passwd-file(joe(a)example.net,255.255.255.255,<Y0lbzmnzfwAuQV80>): Password mismatch 2014-02-27 21:16:46 auth: Info: passwd-file(foobar,255.255.255.255,<Y0lbzmnzfwAuQV80>): unknown user 2014-02-27 21:52:00 auth: Info: passwd-file(foo(a)example.net,255.255.255.255,<0Su6VGrzGwAuQV80>): unknown user 2014-02-27 21:53:35 auth: Info: plain(?,255.255.255.255,<0Su6VGrzGwAuQV80>): Empty username 2014-02-27 21:53:55 auth: Info: plain(?,255.255.255.255,<0Su6VGrzGwAuQV80>): Username character disallowed by auth_username_chars: 0x5c (username: \0) 2014-02-27 22:08:05 auth: Info: plain(?,255.255.255.255): invalid input 2014-02-27 22:09:36 auth: Info: passwd-file(joe(a)example.net,255.255.255.255): Password mismatch 2014-02-27 22:09:53 auth: Info: login(?,255.255.255.255): Empty username # end extract I've tried adding "-L -o info_log_path=/var/log/dovecot-info.log" to the both auth and auth-worker services but that yield nothing. ----------------------%<-------------------------------- auth_mechanisms = plain login auth_verbose = yes base_dir = /var/run/dovecot/ info_log_path = /var/log/dovecot-info.log log_path = /var/log/dovecot.log log_timestamp = "%Y-%m-%d %H:%M:%S " passdb { args = scheme=CRYPT username_format=%u /etc/dovecot/virtual_users driver = passwd-file } userdb { args = username_format=%u /etc/dovecot/virtual_users default_fields = uid=vmail gid=vmail driver = passwd-file override_fields = home=/home/vmail/%d/%u result_failure = return-fail result_internalfail = return-fail } service auth-worker { executable = auth -w -L -o info_log_path=/var/log/dovecot-info.log } service auth { executable = auth -L -o info_log_path=/var/log/dovecot-info.log unix_listener /var/spool/postfix/private/dovecot-auth { group = postfix user = postfix mode = 0660 } } service lmtp { executable = lmtp -L -o info_log_path=/var/log/dovecot-info.log unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix user = postfix mode = 0660 } } ---------------------->%-------------------------------- The relevant postfix config is ... smtpd_sasl_type = dovecot smtpd_sasl_path = private/dovecot-auth virtual_transport = lmtp:unix:private/dovecot-lmtp

[Dovecot] Dovecot2 vs. AD, "Inactivity during authentication"
by Jeroen Scheerder 28 Feb '14

28 Feb '14

Hi, I'm trying to setup Dovecot2 for o IMAP client access o LDA for postfix mail delivery (with SIEVE) ... on a FreeBSD host. The FreeBSD server has no users (by intention), so I've set up a virtual mail domain, using LDAP lookups in Postfix. So far so good. Mail delivers into the proper mailbox. But I'm stuck getting Dovecot to authenticate. User- and passwd DB's are set up for LDAP lookups to AD, using an authenticated bind (the AD server offers no anonymous binds, yet). I've enabled all the debugging I can find, but my logs have little information to offer. Any help in getting me a step further would be much appreciated. In particular, I'd like to learn how do diagnose these userdb/passdb issues properly. Here's what I see in the logs: Feb 27 12:25:49 <mail.info> ponyboy dovecot: imap-login: Disconnected: Inactivity during authentication (disconnected while authenticating, waited 172 secs): user=<>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured, session=<r/ERi2HzQAB/AAAB> Feb 27 12:26:42 <mail.err> ponyboy dovecot: auth: Error: PLAIN(js,127.0.0.1,<r/ERi2HzQAB/AAAB>): Request 74099.1 timed out after 225 secs, state=1 This logging is related to the folloging IMAP session: ponyboy% telnet localhost 143 Trying 127.0.0.1...

[Dovecot] Quota-Status issue
by Cyberonic Turbo 27 Feb '14

27 Feb '14

Following this guide: http://sys4.de/en/blog/2013/04/08/postfix-dovecot-mailbox-quota/ I can't seem to get it to work, as soon as I add the smtpd_recipient_restrictions setting to postfix I can no longer send mail at all. I get the message SMTP Error (450): Failed to add recipient "postmaster(a)example.com" (4.7.1 : Recipient address rejected: Internal error occurred. Refer to server log for more information.). I googled around and found this command to test the quota-status service: printf "recipient=postmaster at example.com\nsize=1234\n\n" | nc 127.0.0.1 12340 It seems to always return the quota_status_nouser message.

[Dovecot] dsync mirror to mailstores in director setup

27 Feb '14

Hi All, I have dsync mirror command working between a standalone dovecot server and a backend mailstore in a Dovecot Director setup. Is it safe to do the dsync directly to the backend mailstore in this setup? It doesn't seem to work via the director proxy. Thanks Murray

[Dovecot] 2 users database on same LDAP with different mail location
by Francesco 26 Feb '14

26 Feb '14

Hello, i know i know, i'm getting annoying but appearently i always come up with weird ideas and i cant seem to accomplish such a task. the scenario is that i have an LDAP server with a bunch of users. some of them are in a specific OU, and i'd like to define for all these users belonging to this OU an alternative mail location/storage. in details for all the users i'd like to use maildir storage in a directory, while for the users belonging to a specific OU i'd like to use dbox with an alternative storage attached. so i created 2 userdb like this: userdb { driver = ldap args = /etc/dovecot/dovecot-ldap-maildir.conf.ext } userdb { driver = ldap args = /etc/dovecot/dovecot-ldap-dbox.conf.ext } and then defined these 2 args files: maildir: hosts = localhost dn = CN=ldapadmin,OU=administrators,DC=plutone,DC=local dnpass = <password> auth_bind = yes ldap_version = 3 base = DC=plutone,DC=local user_attrs = sAMAccountName=home=/var/vmail/%$ dbox: hosts = localhost dn = CN=ldapadmin,OU=administrators,DC=plutone,DC=local dnpass = <password> auth_bind = yes ldap_version = 3 base = OU=dboxusers,OU=lowpriority,DC=plutone,DC=local user_attrs = sAMAccountName=home=/var/local_dbox/%$, =mail=dbox:/var/local_dbox/%$:ALT=/var/iscsi_dbox/%$ user_filter = (&(ObjectClass=person)(mail=%u)) yet it doesn't matter how hard i try if i send an email to a user belonging to the dboxusers OU i still have the user to be addressed to the maildir storage in /var/vmail am i missing something? Thanks Francesco

[Dovecot] Dovecot upgrade 1 to 2 on Debian Squeeze : broken /var/run/dovecot

Hi, I just upgraded from version 1 to version on Debian Squeeze using their backports. Like I expected my dovecot1 config had to be converted using doveconf and this I did. However, I see problems with files inside directory: drwxr-xr-x 4 dovenull root 4096 Feb 25 20:35 /var/run/dovecot All of them were created owned by root:root rw. I tried to changed, for example : chown postfix:dovecot /var/run/dovecot/auth-master but noticed when I restarted dovecot it reset the permissions back to root:root rw.

[Dovecot] Upgrading from 1.2.x -> 2.2.x in one step possible
by Götz Reinicke - IT Koordinator 26 Feb '14

26 Feb '14

Hi, after some off-ML discussions to and some reconsiderations, we might do the "big jump" from our current 1.2.17 to the atrpms 2.2. From googling and reading the dovecot upgrade wiki I don't see any (big) pitfalls. Basically we use the default config options, mbox, pop3s/imaps on RH EL 5. So "just" run the upgrade-config script, fingers crossed and thats it? Ii it possible to do such a big step form 1.2 to 2.2? Thanks for comments and suggestions .

[Dovecot] Removing Mount Points
by Jeff Geiger 26 Feb '14

26 Feb '14

Dovecot version 2.1.7 If a dovecot mount point (drive) dies, and the data is restored into the same path that's no longer a mount point (subfolder), dovecot complains about a missing mount point. Is it safe to do a `doveadm mount remove {path}` to fix the error since it's no longer a legit mount point? Example: We were storing indexes on an SSD drive mounted at /mnt/ssd. That drive died. I was able to put everything back into the /mnt/ssd folder (no longer mounted, just a folder). Everything seems to be working as expected. But, when I just went to dsync an account from another server to this one, I got the following error: dsync(sales(a)foo.com): Error: Couldn't create index dir /mnt/ssd/indexes/6/a/ sales(a)foo.com/mailboxes: Can't create mailbox root dir /mnt/ssd/indexes/6/a/ sales(a)foo.com/mailboxes: Mountpoint /mnt/ssd isn't mounted. Mount it or remove it with doveadm mount remove Would doing a `doveadm mount remove /mnt/ssd` fix my issue, or cause some type of catastrophe? Thanks, Jeff Geiger jeff.geiger(a)firespring.com

Re: [Dovecot] AUTH_USER variable has invalid value in checkpassword Script

26 Feb '14

answering my own questions: > This has somehow changed and now AUTH_USER always > contains the username. This has fatal consequences as no > every owner of a valid certificate can logon as any user. I now use auth_ssl_username_from_cert = yes and this temporarily fixes my problem. Now if user A authenticates with his certificate and claims to be user B he will be logged on as user A. With ssl_username_from_cert = no (default) he was logged in as User B. > I'm absolutely sure that the value of the x500UniqueIdentifier > was stored into the AUTH_USER when I tested my setup > last year. If one looks at the source code, in particular routine env_put_auth_vars() in src/auth/db-checkpassword.c and routine auth_request_get_var_expand_table() in src/auth/auth-request.c it is clear, that this has never worked. The environemnt variable AUTH_USER always contais the username (in all Dovecot versions). It dows NOT contain the Dovecot auth_user-variable. Comparing AUTH_USER with the username makes no sense in a checkpassword-script So here's my next question: How do I find out the original username from within a chackpassword script after it has been replaced by the x500UniqueIdentifier value from a client certificate? Why is request->requested_login_user == NULL in env_put_auth_vars(). request->user contains the x500UniqueIdentifier value from the clients certificate so the original username was replaced and therefore should have been moved into request->requested_login_user.

Hi, we still run dovecot 1.2.17 and upgrading is not planed for some time. But I'm asked to install a sieve system to be used with SOGo soon. What do I have to install / configure? Is installing/configuring the dovecot-sieve-0.1.19 and dovecot-managesieve-0.11.13 enough? We still use mostly the default settings for imaps/pop3s. And of course configure SOGo.

[Dovecot] AUTH_USER variable has invalid value in checkpassword Script
by dovecot.pkoch＠dfgh.net 25 Feb '14

25 Feb '14

Dear dovecot experts: We are using client certificates to authenthicate against a Dovecot server. Our certificates contain a x500UniqueIdentifier. I'm absolutely sure that the value of the x500UniqueIdentifier was stored into the AUTH_USER when I tested my setup last year. This has somehow changed and now AUTH_USER always contains the username. This has fatal consequences as now every owner of a valid certificate can logon as any user. Here are some more details of our setup: We are using a checkpassword-Script that does the following: 1. Read Username and Password from file descriptor 3 2. If (AUTH_CERT=="valid") and (AUTH_USER==Username) then user is authenticated 3 If (AUTH_CERT=="valid") and (AUTH_USER<>Username) then authentication is rejected (User a tries to logon as User B) 4 If (AUTH_CERT<>"valid) we calculate the current OATH value for Usernames TOTP-token and compare that with the provided password. The last step is the reason why we are using a checkpassword script. Our smartphone users cannot use a smartcard but enter a password that was created by an OTP generator, so programming my own checkpassword script was my only option. AUTH_USER contains the username even if the x500UniqueIdentifier from the users certificate does not, so step 2 happens when step 3 should happen. I did the initial testing with Dovecot 2.2.6. At that time we were using both port 143 and 993. We now use Dovecot 2.2.7 and port 993 only. This should not make a difference but I will recompile 2.2.6 right after sending this posting. Kind regards and thank you very much for this wonderful IMAP server Peter Koch current dovecot.conf: --------------------------------------------------------- # Dovecot configuration file default_process_limit = 2048 protocols = imap listen = * base_dir = /var/dovecot/ mail_location = maildir:/mail/%u:LAYOUT=fs ssl_cert = </etc/ssl/certs/imap.crt ssl_key = </etc/ssl/private/imap.key ssl_ca = </etc/ssl/certs/imap-ca.crt ssl_verify_client_cert = yes ssl_cert_username_field = x500UniqueIdentifier service imap-login { inet_listener imap { port = 0 } } service auth { client_limit = 4096 } service anvil { client_limit = 5000 } passdb { driver = checkpassword args = /usr/dovecot/bin/checkpassword } userdb { driver = passwd override_fields = home=/mail/%u } protocol imap { mail_max_userip_connections = 1000 }

[Dovecot] A question regarding doveadm replicator status
by XarHs 25 Feb '14

25 Feb '14

Hello, I am using Dovecot version 2.2.10. I am quite familiar with ssh replication and I managed to set it up correctly. The only problem I see is that when i run the command: doveadm replicator status I get a wrong "Total number of known users" which is a) is different between the two (2) replicated dovecot servers, i.e. in mail1 I get a total of 21 users and in mail2 I get a total of 20 users (it should be the same, correct?) b) is not matching the total number of users I have in each server (mail1, mail2) which I am also getting when counting the total users with "doveadm" service enabled. (the command doveadm user '*' | wc lists a total of 16 users for both mail1, mail2 servers, which is also the total number of users that exist indeed in the LDAP structure with the doveadm service enabled. Is there any way to reset the value of "Total number of known users"? Do I have to delete a file in /var/run/dovecot or something in order to do it? The only way I tried (not successfully though) to reset it is by executing the command: for i in `doveadm user '*'` ;do doveadm replicator remove $i ; done which does empties all existing users (16), but leaves me with Queued 'sync' requests 0 Queued 'high' requests 0 Queued 'low' requests 0 Queued 'failed' requests 0 Queued 'full resync' requests 0 Waiting 'failed' requests 0 Total number of known users 5 in mail1 server and Queued 'sync' requests 0 Queued 'high' requests 0 Queued 'low' requests 0 Queued 'failed' requests 0 Queued 'full resync' requests 0 Waiting 'failed' requests 0 Total number of known users 4 in mail2 server, i.e. the value is 5 (21-16) for mail1 and 4 (20-16) for mail2 server. After seeing that I tried to restart dovecot service, which again ended in the following numbers: Queued 'sync' requests 0 Queued 'high' requests 0 Queued 'low' requests 0 Queued 'failed' requests 0 Queued 'full resync' requests 0 Waiting 'failed' requests 0 Total number of known users 21 in mail1 server and Queued 'sync' requests 0 Queued 'high' requests 0 Queued 'low' requests 0 Queued 'failed' requests 0 Queued 'full resync' requests 0 Waiting 'failed' requests 0 Total number of known users 20 in mail2 server thus their values augmented back to +16, meaning dovecot read succesfully my 16 users. I have not found a way to successfully reset the "Total number of known users" numbers back to the valid 16 users, which is also returned by running the command: doveadm user '*' | wc Why do I have those differences? How is the "Total number of known users" being calculated? What should I do to effectively reset to to the normal value (which in my case is 16)? Thanks in advance.

[Dovecot] tests with metadata module
by Mihai Badici 25 Feb '14

25 Feb '14

--Repost after subscription as list member --- I made some tests with metadata support in dovecot 2.2.10. Previously I had dovecot 2.2.4 with external metadata plugin who work well. I use dovecot with roundcube and roundcube plugins from kolab project . First, the feature activation was tricky and rather undocumented. I spent about half hour googling, after that I set: imap_metadata = yes and mail_attribute_dict = file:%h/shared_metadata I think you cold put those lines in the 20-imap.conf example file commented; that way will be easy for us to activate. Because I changed the location of shared_metadata, all folders was unannotated . I went in folder manager in roundcube and set folder "calendar" as calendar type and so on. That worked and i have: cat shared_metadata: shared/c4268a04da44bb527c5b0000193e0904/vendor/kolab/folder-type event shared/cd5792367fc9cd5196170000193e0904/vendor/kolab/folder-type event shared/33f55d2e8912195209290000193e0904/vendor/kolab/folder-type event shared/32f55d2e8912195209290000193e0904/vendor/kolab/folder-type contact However, it looks like the metadata is not properly read after. Calendar and Contacts folders don't appear in roundcube. I have this crash in dovecot's log: Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(+0x67d81) [0xb7625d81] -> /usr/lib/dovecot/libdovecot.so.0(+0x67e11) [0xb7625e11] -> /usr/lib/dovecot/libdovecot.so.0(i_fatal+0) [0xb75d6af9] -> dovecot/imap() [0x805d3b2] -> dovecot/imap() [0x805d5bc] -> dovecot/imap() [0x805d6c9] -> dovecot/imap(client_handle_input+0x56) [0x805d836] -> dovecot/imap(client_input+0x72) [0x805dcc2] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x38) [0xb7638d98] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0x10e) [0xb7639d6e] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_run+0x48) [0xb7638818] -> /usr/lib/dovecot/libdovecot.so.0(master_service_run+0x28) [0xb75dcb68] -> dovecot/imap(main+0x284) [0x8050f34] -> /lib/libc.so.6(__libc_start_main+0xf5) [0xb743f5a5] -> dovecot/imap() [0x80510a5] Dec 26 09:28:49 imap(mihai.badici): Fatal: master: service(imap): child 4919 killed with signal 6 (core dumps disabled) I logged imap sessions in roundcube and I have: A0003 GETMETADATA "*" (/private/vendor/kolab/folder-type /shared/vendor/kolab/folder-type) On a similar server with the "old" metadata plugin, I have here listed all folders with coresponding annotations.

[Dovecot] Detail improvement: %c variable
by Hadmut Danisch 25 Feb '14

25 Feb '14

Hi, although dovecot is great and almost exactly solving my problems and fitting my requirements, there is an odd detail that causes me problems: The %c variable. (See http://wiki2.dovecot.org/Variables ) I'm managing an IMAP server for an association, which is connected to an LDAP server. Users can connect in three ways: IMAPS from the internet, IMAP from local acccounts, and IMAP through a Web->IMAP interface, which is protected through additional one-time-passwords. The web gateway is intended to be used from untrusted computers as well, so the IMAP password entered through the Web site must not be the same as the password used on IMAPS. I have solved this problem by using %s%c as part of the LDAP user_filter. When people connect over IMAPS, this becomes imapsecured (%s=imap, %c=secured), while an unencrypted connect becomes imap (%s=imap, %c=) Unfortunately, this works only, if the web interface and the IMAP server are located on different (virtual) machines. But if the web gateway and dovecot are no the /same/ machine, this does not work anymore, since %c becomes "secured" on localhost, even if unencrypted. It causes a lot of trouble and headache. Please add a configuration variable to configure, whether %c should become "secured" for unencrypted traffic on the loopback device (localhost). regards Hadmut

[Dovecot] realtime backup with LDA?
by Francesco 25 Feb '14

25 Feb '14

Hello everyone, i was reading the dovecot-lda documentation as i'm using LDA as a delivery agent on my current mailserver configuration. I was curious to know if there are some options for having a message to be delivered to a "twin mailbox" upon delivery. this twin mailbox would work as a backup archive for recovering emails in case the user accidentally deletes them. so if i have a user which is alice i would create a second mailbox named backup_alice or whatever respecting a predictable schema and then every mail delivered to alice would also be delivered to backup_alice. do you know if this can be done? have any example? i was also planning to use shared folders + ACLS to have backup_alice accessible as a read only mailbox directly from the alice imap account. thanks in advance Francesco

Hello people, I am absolute newbie in the world of Dovecot. Before I start learning configuration and plugin writing I want to ensure that what I am trying to do can be done using Dovecot. I want to have a IMAP proxy setup with a module (written by me) that scans email data for some specific content. Any help appriciated. -- View this message in context: http://dovecot.2317879.n4.nabble.com/Dovecot-hooks-tp46887.html Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] Why are ACLs for non-existent mailboxes accepted?
by Boris 25 Feb '14

25 Feb '14

Dovecot 2.2.9-1 accepts SETACL commands that share mailboxes to non-existent mailboxes. There is no error message. Is this intended behavior? I think it's bad because clients present a success message when indeed the intent of the user failed. Typos are hard to catch.

[Dovecot] dsync, a zero-way synchronisation tool?
by Fabiano Sidler 24 Feb '14

24 Feb '14

Hi folks! I have set up dsync replication with SSH according to http://wiki2.dovecot.org/Replication with the exception of having system users and calling doveadm dsync-server directly from authorized_keys, because the wrapper script posted on the above site is needless (at least in 2.2.10). However, while the two instances connect well to each other, no synchronisation is performed at all, the mailboxes happily remain untouched. I've then temporarily replaced SSH with socat and captured the traffic. Any hints what goes wrong? Unfortunately there are no logs to provide... Greetings, Fabiano

[Dovecot] doveadm mailbox command in multi instance setup
by Peer Heinlein 22 Feb '14

22 Feb '14

We're running Dovecot in a multipe instance cluster with individual userdb-querys to different LDAP-Servers. As far as I can see there's no way to use the doveadm mailbox command with different Auth-Sockets or different configurations. While root@dobby4:/etc/dovecot# doveadm user -a /var/run/dovecot-xy/auth-master p.heinlein(a)example.com field value uid 10000 gid 10000 home /mail/example.com/123456/ mail mdbox:~/mdbox quota_rule2 *:storage=50G is working, using doveadm -c /etc/dovecot/dovecot-xy.conf mailbox list -u p.heinlein(a)example.com does NOT an (user unknown). How can use a different auth socket with "doveadm mailbox" commands? (Maybe using the network socket could be a working way, but what about normal way on the command line?)

Dovecot Version: 2.2.12 Postfix Version: 2.9.6 Hello I've configured the quota-status service (socket and port).

How it's possible to debug the quota-status for understand why to postfix the service return DUNNO and not 552 ?

[Dovecot] Syntax of pattern in map section
by da-dovecotlist-15＠abelonline.de 20 Feb '14

20 Feb '14

I can't seem to find any documentation on the meaning/syntax of the "pattern" variable in map sections that are found in dovecot-dict-sql.conf.ext for example. I am trying to setup shared folders. The only thing[1] I found is: >>First you'll need to know what kind of dict paths the code uses. ACL >>plugin uses these paths: >> >>shared/shared-boxes/anyone/$owner >>shared/shared-boxes/user/$user/$owner >>shared/shared-boxes/group/$group/$owner What is a "dict path"? Is this some kind of hard coded identifier in the Dovecot code? I need to understand how they work because I can't use the example in http://wiki2.dovecot.org/SharedMailboxes/Shared. This is because in my PostreSQL table users are not a single column but two columns with the local and domain part[2]: Table "public.shared_mailboxes" Column | Type -----------------------+------------------------ shared_mailbox_local | character varying(64) shared_mailbox_domain | character varying(253) shared_to_local | character varying(64) shared_to_domain | character varying(253) How should a map section look in this case? [1]http://www.dovecot.org/list/dovecot/2009-April/038922.html [2]I did this in order to use REFERENCES to ensure the user exist. Kind regards

Hi List, I have a problem with dovecot 2.2.12 and sieve-filter call: su -c 'sieve-filter -D -v -W -C -u account(a)domain.tld /var/vmail/domain.tld/account/.sieve INBOX.Refilter' vmail gives me sieve-filter(vmail): Error: user account(a)domain.tld: Auth USER lookup failed sieve-filter(vmail): Fatal: Internal error occurred. Refer to server log for more information. on log file I see this: Feb 17 16:21:34 mail1 dovecot: auth-worker(8430): Warning: mysql: Query failed, retrying: Unknown column 'filter' in 'where clause' Feb 17 16:21:34 mail1 dovecot: auth-worker(8430): Error: sql(account(a)domain.tld): User query failed: Unknown column 'filter' in 'where clause' but I never used filter in dovecot: grep -iR filter /etc/dovecot/ gives me no result (and yes the dir is right).

[Dovecot] virtualfolders all mails minus duplicates
by Francesco 19 Feb '14

19 Feb '14

Hello everyone, i'm trying to mess up a bit with virtual folders and i'm trying to perform something like this: i'd like to create an IMAP virtual folder which shows me all the emails in in INBOX and subfolders but by removing "duplicates" what i mean as duplicates? simply i can recognize duplicate emails as the ones with the same message-id in the header (this was just an idea). in that way if i have a message which is present in more then one folder then it's displayed only once. i considered the idea of using message-id in the header as a criteria, but i don't know if this can be done in this way or in any way at all. any suggestion is really welcome. i'm using dovecot 1.2.15. this is a namespace example just for reference: for INBOX: namespace private { separator = . prefix = INBOX. #subscriptions = yes #list = no inbox = yes } for virtuals: namespace private { prefix = v. separator = . location = virtual:/var/utenti/%Ld/%n/VirtualFolders list = yes inbox = no subscriptions = yes hidden = no } as of now i'm running a virtualfolder which shows messages flagged as important which is done like this: INBOX INBOX.* all flagged hope you can provide me with some hints. Thanks very much Francesco

Hi, i want use dovecot and plugin quota to inform users about exceeded space. I also configure postfix to rewrite envelope_sender so envelope_sender<>header: from. Dovecot sent mail with information about exceeded space to email in envelope_sender. It is possible to configure that dovecot sent mail to header from address? I need use sender_canonical_maps in postfix because i want also relay mail outgoing.

[Dovecot] Filtering spam in an offlineimap + dovecot setup
by Alan Schmitt 19 Feb '14

19 Feb '14

Hello, To easily access my mail both offline on my computer and on my phone, I am synchronizing a local copy on my computer using offlineimap. As the spam filtering options provided on the server are not sufficient, I am now looking into client-side spam filtering. My current setup is as follows. Mail is synchronized using offlineimap, and delivered to a local dovecot server: --8<---------------cut here---------------start------------->8--- [Repository LocalIMAP] type = IMAP preauthtunnel = /usr/local/Cellar/dovecot/2.2.10/libexec/dovecot/imap -c ~/.dovecotzimbra.rc --8<---------------cut here---------------end--------------->8--- The configuration of the local server is simply: --8<---------------cut here---------------start------------->8--- protocols = imap mail_location = maildir:~/.Maildir/zimbra:INBOX=~/.Maildir/zimbra/.INBOX --8<---------------cut here---------------end--------------->8--- I then read my mail using gnus, and index it using notmuch. A suggestion I've been considering is use the pigeonhole sieve extprograms plugin (http://wiki2.dovecot.org/Pigeonhole/Sieve/Plugins/Extprograms) to call the spam filter (I've been looking at dspam at the moment). However, I could not find how to configure the use of sieves in the context of offlineimap. Hence my questions: Is it possible to use dovecot sieves in such a setting? Is there a howto that explains how to do it? Should I try to do things in a different way? (I'm ready to change my setup, as long as I can keep an offline copy of my email in sync with a server copy.) Thanks a lot for any suggestion, Alan PS: I used to use SpamSieve (http://c-command.com/spamsieve/) on a Mac Mini that was running continuously as a spam filter drone. This machine has been retired and I'm basically looking for leaner ways to do a similar thing.

[Dovecot] dovecot antispam plugin not found
by Alan Schmitt 19 Feb '14

19 Feb '14

Hello, I'm trying to setup dovecot-antispam, and even though the configuration and the installation seem to have gone well, dovecot is telling me it's not finding it. Here is the symptom: schmitta@top-wifi ~> /usr/local/Cellar/dovecot/2.2.10/libexec/dovecot/imap -c ~/.dovecotzimbra.rc Fatal: Plugin 'antispam' not found from directory /usr/local/Cellar/dovecot/2.2.10/lib/dovecot However there seems to be a plugin there: schmitta@top-wifi ~> ls -al /usr/local/Cellar/dovecot/2.2.10/lib/dovecot/ | grep antispam -rwxr-xr-x 1 schmitta admin 38460 18 fév 22:40 lib90_antispam_plugin.bundle I note that it is the only plugin with the ".bundle" extension, if it's important.

[Dovecot] Virtual folder for selected users only? (1.2.15)
by Sebastian Schäfer 19 Feb '14

19 Feb '14

hi, i want to set up virtual folders just for some users on our mailserver. the server is set up with a virtual system-user for each of our clients having multiple mailboxes/users (provided by dovecot-mysql). mailboxes are located: /var/mails/SYSUSER/MAILBOX f.e. my mailbox-folder is set to /var/mails/bergschaf/sebastian[at]bergschaf.net {homedir} = /var/mails {maildir} = bergschaf/sebastian[at]bergschaf.net user_query = SELECT homedir AS home, concat('maildir:', maildir) AS mail, uid, gid, concat('maildir:storage=', (quota*1024)) as quota FROM mail_users WHERE username = '%u' now i want to add virtual folders to my mailbox without affecting any other client/mailbox on the server. i already tried to add a namespace "virtual" like mentioned in the wiki and in some other hotwo-guides, but this points to the need to create a "virtual"-folder for each mailbox what i would like to avoid. (f.e. location = %h/%u/virtual => /var/mails/sebastian[at]bergschaf.net). is it possible to enable a namespace just for some selected users on the server? if that's not possible - i'm not sure how to set the location-directive correctly, because i can't find a variable pointing to the maildir: %u => sebastian[at]bergschaf.net %h => /var/mails ...but how should i point the location to {homedir}/{maildir}/virtual? thanks! sebastian dovecot --version 1.2.15

[Dovecot] failed: Message has been copied too many times
by Angel L. Mateo 19 Feb '14

19 Feb '14

Hello, I'm running dovecot 2.1.16 in a ubuntu 12.04 server, with lazy_expunge, SiS and mdbox format. The problem I'm having is that the index for one the mailboxes of one of my users is growing too much. This is not the first time of this problem. In previous cases, is because a message is duplicated thousand of times (I haven't found any reason for this). In these cases, moving messages to other folder and moving again to this same folder fixes the problem. So I have tried this, and I have moved all messages from this folder to another one. But this time, after this, indexes directory is still using a lot of space. And the folder seems to have more serious problems: amateo_adm@myotis51:~$ sudo doveadm search -u vlo mailbox BORRADOS.INBOX.MNCS doveadm(vlo): Error: Syncing mailbox BORRADOS.INBOX.MNCS failed: Message has been copied too many times (59306 + -1) I have tried to delete the folder, with the same result: amateo_adm@myotis51:~$ sudo doveadm mailbox delete -u vlo BORRADOS.INBOX.MNCS doveadm(vlo): Error: Can't delete mailbox BORRADOS.INBOX.MNCS: Message has been copied too many times (59306 + -1) And to purge user's mailbox, but it didn't fix the problem. PS: If this could help, BORRADOS. is the namespace used by lazy_expunge plugin. -- Angel L.

Re: [Dovecot] Virtual folder for selected users only? (1.2.15)
by Sebastian Schäfer 19 Feb '14

19 Feb '14

> thats very outdated, you should upgrade 2.1.x / 2.2.x latest I would like to avoid this, because the 1.2.15 is running extremely stable for a long time. (also it's the most recent version on this old squeeze-machine if not using backports) As far as I see, the virtual folders are fully supported since 1.2.x - am I wrong? What are the advantages of upgrading to 2.x? Are there security issues? Thanks! best, sebastian

[Dovecot] Dovecot, mysql, and quota
by David Mehler 19 Feb '14

19 Feb '14

Hello, I'm running dovecot 2.2 and wanting to get quotas going. I've got the plugins loaded appropriately and am wanting to configure a dictionary backend to talk to my mysql database. I've got a single database called mail which has all the mail-related items in it. One table is for virtual users which postfix uses. It looks like this: CREATE TABLE `virtual_users` ( `id` int(11) NOT NULL auto_increment, `domain_id` int(11) NOT NULL, `password` varchar(128) NOT NULL, `email` varchar(100) NOT NULL, PRIMARY KEY (`id`), UNIQUE KEY `email` (`email`), FOREIGN KEY (domain_id) REFERENCES virtual_domains(id) ON DELETE CASCADE ) ENGINE=InnoDB DEFAULT CHARSET=utf8; and a user looks like: INSERT INTO `mail`.`virtual_users` ( `id` , `domain_id` , `password` , `email` ) VALUES ( '1', '1', SHA2( 'PasswordGoesHere', 512) , 'username(a)domain.com' ); plugin { # SQL backend: quota = dict:User quota::proxy::sqlquota } dict { sqlquota = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } Now when creating the quota table i'd like to have the username field linked to my virtual_users table username field, so I don't have to set up two tables both with the same username information in it. Can someone check me on this design so that if I delete a virtual user out of the virtual_users table the coresponding row in the quota table is also eliminated? My second question has to do with global and per user quotas. If I have something like this: CREATE TABLE quota ( username varchar(100) not null, bytes bigint not null default 262144, messages integer not null default 0, primary key (username) ); 256MB for all users by default, but then if I give a user a 100MB value in the bytes field of their quota entry would that be a per-user quota? Thanks. Dave.

[Dovecot] Index corruption with 2.2.12 when moving a message
by Bojan Smojver 19 Feb '14

19 Feb '14

Just bumped into this today, when I upgraded to a testing package in Fedora: https://admin.fedoraproject.org/updates/FEDORA-2014-2672/dovecot-2.2.12-1.f… For details, see this bug: https://bugzilla.redhat.com/show_bug.cgi?id=1066709 Haven't seen this kind of thing before. Sure, it worked the second time I tried to move the message to another folder (I'm guessing index got rebuilt or something), but still, looks suspicious. Anyway, I'm using mbox format mailboxes, if it matters. Client was Gnome Evolution 3.10.4. -- Bojan

[Dovecot] Problems with dovecot 2.1.7, spamassassin 3.3.2 and antispam plugin
by Dean Carpenter 18 Feb '14

18 Feb '14

This might be a fairly long message, but I wanted to be sure to include as much information as possible. I'm having an issue with the dovecot-antispam plugin in that it seems to be unable to successfully run anything from the pipe backend. To qualify that, they run, but they fail ... Running /usr/bin/sa-learn directly always returns with an error code of 1, and the bayes DB isn't actually updated. Running the /usr/local/bin/sa-learn-pipe.sh script from the example will run sa-learn successfully, but sa-learn fails partway through, right on a sql DB access. I have both bayes and FuzzyOcr data stored in mysql, and the error occurs on accessing either one. That is, I've tested with FuzzyOcr enabled, and it fails on the db access to the FuzzyOcr DB, and I've tried it with FuzzyOcr disabled. In that case, it fails on the access to the bayes DB. The error line right there is : libgcc_s.so.1 must be installed for pthread_cancel to work Since sa-learn terminated prematurely, the bayes DB isn't updated at all. Running /usr/bin/sa-learn or the script /usr/local/bin/sa-learn-pipe.sh directly from cmdline works fine though - sa-learn completes correctly and updates the bayes DB properly, I can see the new tokens. $ sa-learn-pipe.sh --spam < /usr/share/doc/spamassassin/examples/sample-spam.txt $ sa-learn --spam /usr/share/doc/spamassassin/examples/sample-spam.txt I think it would be great to have a dedicated logfile for antispam, one that would capture both stdout as well as stderr. These tests are being done on a clean Ubuntu 13.04 system. I'm rebuilding the VM repeatedly as I configure the various pieces, and can test any changes or whatever you might suggest very easily. I've fully scripted the install and configuration of Exim4, Dovecot, Spamassassin, Clamav, Percona/Mysql, Roundcube, and can build a full VM under Virtualbox or any VPS in less than 10 minutes. Ubuntu 13.04 Dovecot 2.1.7 dovecot-antispam 2.0+20120225-3 Anyone else using the antispam plugin with spamassassin 3.3.2 ?

[Dovecot] SMTP configuration for director mail cluster
by Murray Trainer 18 Feb '14

18 Feb '14

HI All, I have setup my Dovecot director proxies and Dovecot backend mail stores. I intend setting up several incoming and outgoing Exim MTA's. I am a bit confused about what I need to run on the backend Dovecot MTA's to get the incoming mail delivered to them. Do I need to install Exim on them or use LMTP to receive mail from the MTA's? Also, can I directly deliver mail to the mailstores or do I have to go through the director proxies using lmtp? Note that I am using Director with the mailboxes on NFS backed storage. Thanks Murray

[Dovecot] PARTIAL results and UIDs
by Anders Thøgersen 18 Feb '14

18 Feb '14

Hi, I have had a look at dovecot 2.2.12 and think that I may have run into an issue with PARTIAL results. I have a mailbox with 9 emails having UIDs from 1 - 9. One of these emails contains the STRING "RFC" in the Subject header. The following SORT command with this mailbox selected does not return any emails: A4 UID SORT RETURN (COUNT PARTIAL 1:3) (FROM) UTF-8 (SUBJECT "RFC") * ESEARCH (TAG "A4") UID PARTIAL (1:3 NIL) COUNT 1 A4 OK Sort completed (0.000 secs). Here COUNT is 1, but the result is NIL. Changing the partial range to 1:5 returns the expected result: A4 UID SORT RETURN (COUNT PARTIAL 1:5) (FROM) UTF-8 (SUBJECT "RFC") * ESEARCH (TAG "A4") UID PARTIAL (1:5 5) COUNT 1 A4 OK Sort completed (0.000 secs). It may be that UIDs are used instead of sequence numbers. Regards Anders

[Dovecot] Possible error in function mailbox_autocreate
by Potapov Sergey 18 Feb '14

18 Feb '14

Hi! in mailbox_autocreate: if (mailbox_create(box, NULL, FALSE) < 0) { errstr = mailbox_get_last_error(box, &error); if (error != MAIL_ERROR_NOTFOUND) { <<< May be MAIL_ERROR_EXISTS should be here? mail_storage_set_critical(box->storage, "Failed to autocreate mailbox %s: %s", box->vname, errstr); return -1; } Some time I got this error when two connections tries to create INBOX at same time. ______ С уважением, Сергей Потапов

[Dovecot] The submission server
by Peter Mogensen 17 Feb '14

17 Feb '14

Hi, As many others I'm looking forward to the submission server. But I have a question: A use-case with authenticated SMTP is to have the server restrict From/Sender headers based on the authenticated user. (and adding the actual authenticated user to the headers) Postfix supports this (AFAICS) and I can't imagine Exims doesn't either with it's elaborate config possibilities. But will that be possible with the Dovecot submission server? /Peter

[Dovecot] Master user ldap config
by Roman Gelfand 17 Feb '14

17 Feb '14

I am using outlook 2010 to login to pop3 mailbox as master user. The user name I provide is john@domain.tld*test@domain.tld. The password is that of test(a)domain.tld. I am not quite sure as to how to specify ACL. I guessed the ACL specs as per ldap config, below. But it is not working. The master password is stored in master-users file. The ldap config is # debug_level = 9 hosts = 192.168.0.22:389 ldap_version = 3 auth_bind = yes dn = dlookup(a)domain.local dnpass = password base = OU=Test Users,DC=domain,DC=local scope = subtree deref = never user_filter = (&(Mail=%u)(objectClass=person)(!(userAccountControl=514))) pass_filter = (&(Mail=%u)(objectClass=person)(!(userAccountControl=514))) pass_attrs = uid=user, userPassword=password, =proxy=y, =destuser=%u*masteruser, =pass=mastpass default_pass_scheme = CRYPT user_attrs = =uid=999,=gid=8,=home=/vmail/%Ld/%Ln/home/,=mail=maildir:/vmail/%Ld/%Ln/Maildir/ The dovecot.conf is auth_mechanisms = plain login disable_plaintext_auth = no base_dir = /var/run/dovecot/ log_path = /var/log/dovecot.log info_log_path = /var/log/dovecot.info.log mail_debug = no auth_debug = no auth_verbose = no auth_debug_passwords = no first_valid_gid = 8 instance_name = test last_valid_gid = 8 log_timestamp = "%Y-%m-%d %H:%M:%S " mail_location = maildir:~/Maildir mail_privileged_group = mail passdb { args = /etc/dovecot/conf.d/users.conf driver = passwd-file } passdb { args = /etc/dovecot/dovecot-ldap-test.conf driver = ldap } auth_master_user_separator = * passdb { driver = passwd-file args = /etc/dovecot/master-users master = yes pass = yes } service auth { inet_listener { port = 10305 } unix_listener auth-master { group = mail mode = 0600 user = mail } } userdb { args = /etc/dovecot/conf.d/users.conf driver = passwd-file } userdb { args = /etc/dovecot/master-users driver = passwd-file } userdb { args = /etc/dovecot/dovecot-ldap-test.conf driver = ldap } protocol lmtp { postmaster_address = postmaster(a)domain.tld mail_plugins = sieve } protocol lda { postmaster_address = postmaster(a)domain.tld hostname = server.domain.tld # Sieve plugin for local delivery agent mail_plugins = cmusieve log_path = /var/log/dovecot-local-deliver.log }

[Dovecot] FTS question
by Peter Chiochetti 14 Feb '14

14 Feb '14

Please advise: Can I override the user parameter in solr indexing and searching? To understand, why I wish for that, please consider my setup: # Mail is fetched from a remote imap server # dovecot LDA stores into Maildir as system user # Several virtual users exist in a static userdb # They all share the system users Maildir # everybody can see, move, delete etc. all the mails # dovecot mail_log plugin is used for audit So it is like all/only shared folders, isn't it? A cheap groupware, maybe… This works exceptionally well (2.0 and 2.2.11 as of now). The problem: When e-mails are indexed by solr, the uid of the virtual user is passed on, and only this user will later find that mail in a server side body search. I tried and made "user" an ignored field in solr schema, but then nothing will ever be found, because it is dropped when indexing, but will be asked for in searching. So far, what I learned in a day. Maybe someone can help? Thank You in advance -- peter

Re: [Dovecot] Maildir format
by Roman Gelfand 14 Feb '14

I am not sure where I went wrong here. The wiki says... By default Dovecot uses Maildir++ directory layout for organizing mailbox directories. This means that all the folders are directly inside ~/Maildir directory: ~/Maildir/new, ~/Maildir/cur and ~/Maildir/tmp directories contain the messages for INBOX. The tmp directory is used during delivery, new messages arrive in new and read shall be moved to cur by the clients. ~/Maildir/.folder/ is a mailbox folder ~/Maildir/.folder.subfolder/ is a subfolder of a folder (ie. "folder/subfolder") You can also optionally use the "fs" layout by appending :LAYOUT=fs to mail_location. This makes the folder structure look like: ~/Maildir/new, ~/Maildir/cur and ~/Maildir/tmp directories contain the messages for INBOX, just like with Maildir++. ~/Maildir/folder/ is a mailbox folder ~/Maildir/folder/subfolder/ is a subfolder of a folder Here is my folders. Though there are emails in the inbox, I am not seeing anything in new/ or cur/ folders. root@mbx:/etc/dovecot# ls -la /vmail/domain.tld/j.doe/Maildir/ drwx------ 5 999 mail 4096 Feb 14 10:06 . drwx------ 3 999 mail 4096 Feb 12 19:53 .. drwx------ 2 999 mail 4096 Feb 14 10:02 cur -rw------- 1 999 mail 17408 Feb 14 10:02 dovecot.index.cache -rw------- 1 999 mail 2896 Feb 14 10:06 dovecot.index.log -rw------- 1 999 mail 51 Feb 14 10:06 dovecot-uidlist -rw------- 1 999 mail 8 Feb 12 19:53 dovecot-uidvalidity -r--r--r-- 1 999 mail 0 Feb 12 19:53 dovecot-uidvalidity.52fc176c drwx------ 2 999 mail 4096 Feb 14 10:02 new drwx------ 2 999 mail 4096 Feb 14 09:59 tmp root@mbx:/etc/dovecot# ls -la /vmail/domain.tld/j.joe/Maildir/new total 8 drwx------ 2 999 mail 4096 Feb 14 10:02 . drwx------ 5 999 mail 4096 Feb 14 10:06 .. root@mbx:/etc/dovecot# ls -la /vmail/domain.tld/j.joe/Maildir/cur total 8 drwx------ 2 999 mail 4096 Feb 14 10:02 . drwx------ 5 999 mail 4096 Feb 14 10:06 ..
