[Dovecot] BUG: segmentation fault in auth

Hi I'm getting segmentation fault in Dovecot 2.2.11. This happens when trying to do a user lookup by "doveadm user".

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

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.

[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
by dovecot＠voidptr.de 06 Mar '14

06 Mar '14

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.

[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. It syslogs, and the syslogs show that the LDAP parts working as expected: Mar 3 14:49:09 <mail.info> ponyboy checkpassword: successful authenticated bind and DN(js) lookup Mar 3 14:49:09 <mail.info> ponyboy checkpassword: DN(js) is CN=Jeroen Scheerder,OU=Users,OU=Netherlands,OU=ON2IT,DC=office,DC=on2it,DC=net Mar 3 14:49:09 <mail.info> ponyboy checkpassword: js authenticated In dovecot's log, simultaneously, I see basically a successful login, except that the (user_)uid and (userdb_)gid work - unless I disable prefetch, and use a static userdb: Mar 03 14:49:04 auth: Debug: Loading modules from directory: /usr/local/lib/dovecot/auth Mar 03 14:49:04 auth: Debug: Read auth token secret from /var/run/dovecot/auth-token-secret.dat Mar 03 14:49:04 auth: Debug: auth client connected (pid=90856) Mar 03 14:49:09 auth: Debug: client in: AUTH 1 PLAIN service=imap secured session=+qFODbTzDgB/AAAB lip=127.0.0.1 rip=127.0.0.1 lport=143 rport=63246 resp=<hidden> Mar 03 14:49:09 auth: Debug: checkpassword(js,127.0.0.1,<+qFODbTzDgB/AAAB>): execute: /usr/local/etc/dovecot/checkpassword-on2it /usr/local/libexec/dovecot/checkpassword-reply Mar 03 14:49:09 auth: Debug: checkpassword(js,127.0.0.1,<+qFODbTzDgB/AAAB>): Received input: userdb_uid=143 userdb_gid=143 Mar 03 14:49:09 auth: Debug: checkpassword(js,127.0.0.1,<+qFODbTzDgB/AAAB>): exit_status=0 Mar 03 14:49:09 auth: Debug: client passdb out: OK 1 user=js Mar 03 14:49:09 auth: Debug: master in: REQUEST 4007395329 90856 1 29571963894e557ab643d2e51872ba55 session_pid=90899 request_auth_token Mar 03 14:49:09 auth: Debug: prefetch(js,127.0.0.1,<+qFODbTzDgB/AAAB>): success Mar 03 14:49:09 auth: Debug: master userdb out: USER 4007395329 js uid=143 gid=143 auth_token=e2d7c2463dd4c039010e904afb4ea45214cb7de5 Mar 03 14:49:09 imap-login: Info: Login: user=<js>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=90899, secured, session=<+qFODbTzDgB/AAAB> Mar 03 14:49:09 imap: Error: user js: Mail access for users with UID 143 not permitted (see first_valid_uid in config file, uid from userdb lookup).

[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

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).

[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. I'm really stumped here. What logs do I need to check for errors and does anyone have any experience with this?

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

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.

[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

[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] Dovecot / Postfix and the quota-status
by nathan＠schultheiss.fr 22 Feb '14

Dovecot Version: 2.2.12 Postfix Version: 2.9.6 Hello I've configured the quota-status service (socket and port). When I call the service with shell, he replied request=smtpd_access_policy sender=sender(a)domain.tld recipient=recipient(a)domain.tld size=100000 action=552 5.2.2 Mailbox is full In shell the service returns a 552 when the quota is exceeded, but when postfix call it, the service return alway DUNNO. How it's possible to debug the quota-status for understand why to postfix the service return DUNNO and not 552 ? The mailbox it's overquota already, all quota check with shell return the good reply (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

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.

[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

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 18 Feb '14

18 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 }

Hi, I have the same crashes in pop3 with the recent dovecot release 2.2.11 on Fedora 16 x86_64.

[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 ..

[Dovecot] Hybrid of linux user accounts and virtual user accounts configuration
by Derek Winterstien 14 Feb '14

14 Feb '14

So some system users have their email forward to Maildir in their /home/user directory (virtual_alias_maps) for their domain . This I have working! And the rest are non-system users, ie virtual users listed in a plain text file and their MailDir will be in /home/vmial/domain.com/user/ The virtual user part is working 100% with postfix and dovecot accepting mail for each virtual alias and system account holders popping in to retrieve their mail. The second part is working 50%. I have email for virtual users going into /home/vmail/domain.com where they are supposed to go. Now, I am very confused on how to configure dovecot to allow folks without system accounts to login and retrieve their email. I have been going through one guide after another. When I start changing things I break the first working part, the system accounts being able to get their mail. Changes to dovecot.conf to get the second working negatively impact the first. Also, a lot of documentation is out of date, which further complicates matters. Postfix/Dovecot: Postfix version: 2.6.6 Dovecot version: 2.0.9

[Dovecot] Feature request about Info: Internal login failure (pid=2296 id=17278) (internal failure, 1 successful auths)
by Steffen Kaiser 14 Feb '14

14 Feb '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, since some time I'm plagued by internal login failures. With v2.2.10 I got the some additional error, that I should raise the process_limit for the imap service, then I got the hint to raise vsz_limit for the lmtp and imap serverices. These hints are very helpful and are some sort of unique feature of Dovecot - descriptive error messages. Now I have upgraded a Webfrontend behind imapproxy -> Dovecot and get this during a phase in the day, several of messages go to large internal mailing lists and lots of users are connecting/disconnecting via IMAP, POP,& Web: <login success> imap: Error: Disconnected from auth server, aborting (client-pid=2296 client-id=17278) imap-login: Info: Internal login failure (pid=2296 id=17278) (internal failure, 1 successful auths) .... . doveadm and to query the userdb [I have some processes that use Dovecot UserDB to query user data, which do not cache its information], & login into IMAP fail as well. Even connecting to the auth-userdb socket reveals no reaction - usually the VERSION prompts immediately. I now suppose that the deault auth_worker_max_count=30 is the culprit, because I query LDAP for passdb and userdb and client_count, but client_limit=0. Would it be possible to add a warning to all limits "that max out"? Or, if such "generic error" occurs, could Dovecot be enabled to dump a list of which limit is used up to which level? Or something like that. Also, I'm surprised to find that the "Internal login failure" is at "Info" level only. Also note: It is very possible that the problem is caused by a client that goes havoc. ====== Just to no trigger the "post your config" reply I give now and then myself: # 2.2.10 (5432b55a2b87): /usr/local/dovecot-2.2.10/etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-amd64 x86_64 Debian 6.0.8 auth_cache_size = 10 M auth_debug = yes auth_mechanisms = plain login auth_verbose = yes base_dir = /var/run/dovecot2.2/ default_vsz_limit = 512 M deliver_log_format = msgid=%m: %$ %p/%w "%f" "%s" dict { acl = pgsql:/usr/local/dovecot-2.2.10/etc/dovecot/dovecot-dict-sql.conf.ext quota = pgsql:/usr/local/dovecot-2.2.10/etc/dovecot/dovecot-dict-sql.conf.ext } instance_name = dovecot2.2 lda_mailbox_autocreate = yes lmtp_save_to_detail_mailbox = yes log_path = /var/log/dovecot/dovecot2.2.log log_timestamp = "%F %H:%M:%S " mail_debug = yes mail_gid = vmail mail_log_prefix = "%Us(%u) [%p]: " mail_max_userip_connections = 0 mail_plugins = " quota notify mail_log zlib acl" mail_shared_explicit_inbox = yes mail_uid = vmail 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 imapflags namespace { list = children location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u prefix = users.%%u. separator = . type = shared } namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { args = /usr/local/dovecot-2.2.10/etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { acl = vfile acl_shared_dict = proxy::acl antispam_allow_append_to_spam = yes antispam_backend = spool2dir antispam_spam = SPAM+ReportAsSPAM antispam_spool2dir_notspam = /tmp/spamspool/%%020lu-%%05lu-%u-H antispam_spool2dir_spam = /tmp/spamspool/%%020lu-%%05lu-%u-S antispam_trash = trash;TRASH;Trash;spam;SPAM;Spam;junk;JUNK;Junk;Deleted Items;Deleted Messages;Gel&APY-schte Elemente;Gel&APY-schte Objekte;Junk E-mail;Junk-E-Mail;INBOX.Trash;INBOX.TRASH;INBOX.trash mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename mail_log_fields = uid box msgid size vsize from subject quota = dict:User quota::proxy::quota quota_rule = *:storage=300MB quota_rule2 = Trash:storage=+30M recipient_delimiter = + sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_extensions = +imapflags sieve_max_actions = 0 sieve_quota_max_storage = 3M } protocols = imap pop3 lmtp sieve quota_full_tempfail = yes service auth { unix_listener auth-client { mode = 0766 } unix_listener auth-userdb { mode = 0766 user = vmail } } service dict { unix_listener dict { group = vmail mode = 0660 user = vmail } } service doveadm { unix_listener doveadm-server { mode = 0666 } } service imap-login { process_min_avail = 4 service_count = 0 vsz_limit = 768 M } service imap { process_limit = 10000 vsz_limit = 768 M } service lmtp { vsz_limit = 768 M } service managesieve-login { inet_listener sieve { port = 4190 } inet_listener sieve_deprecated { port = 2000 } } service pop3-login { process_min_avail = 5 service_count = 0 vsz_limit = 512 M } ssl_ca = </etc/ssl/certs/ca.crt ssl_cert = </etc/ssl/certs/imap.pem ssl_key = </etc/ssl/private/imap.key userdb { driver = prefetch } userdb { args = /usr/local/dovecot-2.2.10/etc/dovecot/dovecot-ldap.conf.ext default_fields = home=/home/%u uid=vmail gid=vmail driver = ldap } verbose_proctitle = yes protocol lmtp { mail_plugins = " quota notify mail_log zlib acl quota sieve" } protocol lda { mail_plugins = " quota notify mail_log zlib acl quota sieve" } protocol imap { mail_plugins = " quota notify mail_log zlib acl imap_quota imap_zlib imap_acl antispam" } - -- Steffen Kaiser -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQEVAwUBUvjzZnD1/YhP6VMHAQKElQgAoBU3v5JD9kFNzan06UFG88sucvf6HZru gLF6l7IZSWiY/IwouTBoseJcrXmgVG9sCk12gxvonO3iT0KVu1PyJZeTMaKtY3hS I37J4iS88pmY3cGQNguYMSidrIvNOt6SW+Jv/9QxuYTJKYCqoEZRdP8yJ+dvrmQw zpZEzKqcV+x4ofDLcpRxLZtXwb+Bl5AA9hoe/Md/UqzUEa9CYyvANoX63/zY7WS5 1VpK+a80/L6ukJUt9tPQTWSe0ALYmL6Cd4tAdC2Bsq7rN+6SQIcjxxr/9v8Byj8Q BdtwUhpTazVm7CLOjnFiWxfXmHCL9BNrQUBBAd5docSydNDEUMmQng== =r9QR -----END PGP SIGNATURE-----

[Dovecot] Status
by Timo Sirainen 14 Feb '14

14 Feb '14

So, just some quick notes: - dovecot.org server was down a couple of days again, need to find time to move it to a VM.. - my tss(a)iki.fi emails were also broken for some hours at least and it was bouncing back all mails to it during the time - I fixed some bugs reported by people, but I did it in airplane so couldn't reply back with links to the fixes in hg repo. I'll probably do that tomorrow. But you can already check if your reported bug has been fixed in http://hg.dovecot.org/dovecot-2.2 - I'm planning on going through Dovecot list's mails this week and make v2.2.11 release - although it looks like I've a flu, so lets see how far I can get.. - hopefully by the beginning of March I'll have more time again

[Dovecot] Sieve is not getting the propper RCPT from the LMTP daemon
by klondike 14 Feb '14

14 Feb '14

Hi! Since the setup I use is a bit strange let's go for it first: * The system uses postfix as MTA and dovecot as LDA after alias translation by local via LMTP * The dovecot version is 2.2.5 and the pigeonhole version is 0.4.1 * The SMTP server at gentoo.org is configured to send me a backup of my emails to klondike+gentoo (at) xiscosoft.es using sendmail * The email is received by the server and then (hopefully filtered). * The email comes with two Delivered-To: headers, the first one has the correct address, the second one has the gentoo address. The interesting part of the filter is this: if envelope :detail "to" "gentoo" { addflag "\\Seen"; fileinto "gentoo"; stop; } But this doesn't seem to work, I enable debugging with the following lines: require "vnd.dovecot.debug"; require "envelope"; require "variables"; if envelope :matches "to" "*" { debug_log "envelope to `${1}'"; } if envelope :matches "from" "*" { debug_log "envelope from `${1}'"; } The relevant lines for the test e-mail I sent are these: sieve: info: started log at Dec 24 13:37:23. main script: line 9: info: DEBUG: envelope to `klondike (at) gentoo.org'. main script: line 10: info: DEBUG: envelope from `klondike (at) gentoo.org'. info: msgid=<52B97FF7.6050109(a)gentoo.org>: stored mail into mailbox 'INBOX'. The thing is that the to envelope should be instead klondike+gentoo (at) xiscosoft.es as show by the lmtp logs: Dec 24 13:37:23 localhost dovecot: lmtp(26249): Connect from local Dec 24 13:37:23 localhost dovecot: lmtp(26249, klondike): Cd6YHwOAuVKJZgAA0J78UA: sieve: msgid=<52B97FF7.6050109(a)gentoo.org>: stored mail into mailbox 'INBOX' Dec 24 13:37:23 localhost dovecot: lmtp(26249): Disconnect from local: Successful quit Dec 24 13:37:23 localhost postfix/lmtp[26248]: 657D9101E5E: to=<klondike+gentoo (at) xiscosoft.es>, relay=xiscosoft.net[private/dovecot-lmtp], delay=0.29, delays=0.05/0.03/0.03/0.18, dsn=2.0.0, status=sent (250 2.0.0 <klondike+gentoo (at) xiscosoft.es> Cd6YHwOAuVKJZgAA0J78UA Saved) I really have no idea of why sieve is behaving like this as the evelope address is sent properly by postfix's lmtp according to the logs. Any ideas? klondike PS: please do CC me when answering this e-mail as I'm not subscribed to the list yet

[Dovecot] master user and ACL's
by Peter Mogensen 14 Feb '14

14 Feb '14

Hi, Quick question...I read in the docs that: "Master user is still subject to ACLs just like any other user, which means that by default the master user has no access to any mailboxes of the user." ... and that the standard workaround is to return master_user=%u from the userdb. But why is the master_user authn-id used in the ACLs and not the authz-id (requested-login-user) ? Isn't the whole point of SASL authz-id semantics to have authorization resolved based on the authz-id? /Peter

[Dovecot] Public folder doesn't work
by vupibi 14 Feb '14

14 Feb '14

Hey, I have some issues with dovecot, because the public folder won't show up in Mail accounts. Dovecot is installed via zentyal 3.3. I tried several settings, but I dont get it running. What I tried is adding this to my dovecot.conf file # User's private mail location mail_location = maildir:~/Maildir # When creating any namespaces, you must also have a private namespace: namespace { type = private separator = / prefix = #location defaults to mail_location. inbox = yes } namespace { type = public separator = / prefix = Public/ location = maildir:/var/vmail/public subscriptions = no } But nothing happened. I tried it with # Umask for shared folders umask = 0007 with subscriptions = yes tried creating the folder first like this touch /var/vmail/public/dovecot-shared chown -R ebox /var/vmail/public find /var/vmail/public -type d -print0 | xargs -0 chmod 2770 find /var/vmail/public -type f -print0 | xargs -0 chmod 660 But i had no success. Any Ideas how to get it running?

[Dovecot] Exclude Users from replication/sync
by Daniel Stoye 14 Feb '14

14 Feb '14

Hi All, i'm searching for a way to exclude certain users from dovecots replication mechanism. I can't use the first_valid_uid setting, because the uid of my pam (ldap) users und my system users are mixed up. So, is there a way to limit my users i currently have in my userdb or somehow exclude specific uids from replication? Thanks, Daniel

[Dovecot] v2.2.12 released
by Timo Sirainen 14 Feb '14

14 Feb '14

http://dovecot.org/releases/2.2/dovecot-2.2.12.tar.gz http://dovecot.org/releases/2.2/dovecot-2.2.12.tar.gz.sig POP3 server code changes rarely, so I haven't spent time adding automated testing for it. So of course now that it changed in v2.1.11 there was a bug that caused it to crash most of the time (except for the test case I was using while developing it). This release fixes it, no other changes.

[Dovecot] Dovecot 2.2.10 crash / infinite loop bug
by Jani Hast 14 Feb '14

14 Feb '14

Hello, I though this bug should be reported, although there is workaround already made and in use. Dovecot 2.2.10 crashes into out of memory error when there is defined system users (userdb+passdb) and own virtual users (userdb+passdb). Removing either one solves the issue and Dovecot is working as it should. When memory leak (I replaced pw_init and gr_init with the version that is found from 2.1.17) is fixed from lib/ipwd.c source, the auth worker gets to infinite loop and authentication timeouts(timeout was increased, but worker does not end what ever it's doing). This far I got chance to debug this before other passdb was removed due lack of time. Here's logs, configs and backtrace: Feb 1 07:39:19 openbsd dovecot: auth-worker(30906): Fatal: pool_system_realloc(268435456): Out of memory Feb 1 07:39:19 openbsd dovecot: auth: Error: auth worker: Aborted request: Worker process died unexpectedly Feb 1 07:39:19 openbsd dovecot: auth-worker(30906): Fatal: master: service(auth-worker): child 30906 returned error 83 (Out of memory (service auth-worker { vsz_limit=256 MB }, you may need to increase it) - set CORE_OUTOFMEM=1 environment to get core dump) Feb 1 07:39:19 openbsd dovecot: auth: Error: static(email@localhost): passdb doesn't support lookups, can't verify user's existence Feb 1 07:39:19 openbsd dovecot: lda: Error: user email@localhost: Auth USER lookup failed Feb 1 07:39:19 openbsd dovecot: lda: Fatal: Internal error occurred.

[Dovecot] sqlite queries for master user
by Alan Chandler 14 Feb '14

14 Feb '14

Hi I am trying to achieve the following functionality "usera" can't login because his account is set non active. there is a deny query that checks this. a master user ("masteruser") should be able login using "usera*masteruser" syntax to this disabled account I just tried it with auth_debug set on, but the deny query is being run for usera, presumably because my master definition is passdb { driver = sql master = yes args = /etc/dovecot/sqlite-master.conf # Unless you're using PAM, you probably still want the destination user to # be looked up from passdb that it really exists. pass=yes does that. pass = yes } with pass=yes, and that causes usera to be validated through both the deny and accept phase of authorisation. In the password_query defined in sqlite-master.conf I user '%u' to locate my master user. Is there any variable I could use to (in that query) to also check that "usera" exists? I could then remove the pass = yes, both to avoid two more queries and to avoid the trap that this account is locked out. Alternatively some other parameter in the passdb segment above to tell the other login to miss the deny stage.

[Dovecot] v2.2.11 released

13 Feb '14

http://dovecot.org/releases/2.2/dovecot-2.2.11.tar.gz http://dovecot.org/releases/2.2/dovecot-2.2.11.tar.gz.sig I haven't had time to read through the Dovecot mailing list yet, so there are likely some reported bugs that haven't been fixed yet. I'll try to get to them next week in San Francisco. (Probably can't get much done this week in Tokyo.) In the mean time here's v2.2.11 with some new features. + acl plugin: Added an alternative global ACL file that can contain mailbox patterns. See http://wiki2.dovecot.org/ACL for details. + imap proxy: Added proxy_nopipelining passdb setting to work around other IMAP servers' bugs (MS Exchange 2013 especially). + Added %{auth_user}, %{auth_username} and %{auth_domain} variables. See http://wiki2.dovecot.org/Variables for details. + Added support for LZ4 compression. + stats: Track also wall clock time for commands. + pop3_migration plugin improvements to try harder to match the UIDLs correctly. - imap: SEARCH/SORT PARTIAL reponses may have been too large. - doveadm backup: Fixed assert-crash when syncing mailbox deletion.

[Dovecot] can not see public mailbox
by David Mehler 13 Feb '14

13 Feb '14

Hello, I'm running Dovecot2 and trying to set up public mailboxes. I've got a virtual user system set up with postfix and using MySQL authentication. I'm wanting to create several public mailboxes for shared messages. I've followed the wiki and have the public folder created. I've got a folder /home/vmail/public/public1 public1 being the maildir of the public mailbox. I can see in my folder list of my webmail client the root public folder but I can't change in to it and I can not see the public1 public mailbox.

[Dovecot] Order of istream and ostream chains
by Philipp Brüll 12 Feb '14

12 Feb '14

Hi, I'm creating a scrambler plugin, that adds an istream and an ostream to the stream-chain for the mail input/output. It works well until the zlib plugin is added to the configuration. The scrambler should run before the zlib and encrypt the mail before it's compressed. Since, the plugin is named lib18_scrambler_... (and the other lib20_zlib....), that works well when a mail is received. When a mail is read via IMAP, the plugins should handle the mail in the reverse order. So first, the zlib should decompress it and afterwards the scrambler should decrypt it. But it seems, that they work the other way around. The scrambler istream gets compressed data as input. It's hooked in the chain of istream as the following... static int scrambler_istream_opened(struct mail *_mail, struct istream **stream) { struct mail_private *mail = (struct mail_private *)_mail; union mail_module_context *mmail = SCRAMBLER_MAIL_CONTEXT(mail); struct istream *input, *inputs[2]; input = *stream; *stream = scrambler_istream_create(input); i_stream_unref(&input); return mmail->super.istream_opened(_mail, stream); } static void scrambler_mail_allocated(struct mail *_mail) { struct mail_private *mail = (struct mail_private *)_mail; struct mail_vfuncs *v = mail->vlast; union mail_module_context *mmail; mmail = p_new(mail->pool, union mail_module_context, 1); mmail->super = *v; mail->vlast = &mmail->super; v->istream_opened = scrambler_istream_opened; MODULE_CONTEXT_SET_SELF(mail, scrambler_mail_module, mmail); } How can I reverse the order of istreams? Should I use another hook or vfuns? I'm stuck in the problem for a while now, so any help would be very welcome. Best regards, Philipp

[Dovecot] personal sieve script not included
by Thomas Krause 12 Feb '14

12 Feb '14

Hello, I'm using dovecot 2.2.10 and roundcube (with managesieve enabled). Sieve filtering works well, as long the rule is written into ~/.dovecot.sieve (which is a link to ~/sieve/managesieve.sieve) When adding a new filter set (in roundcube) the script is written to ~/sieve/newfilterset.sieve. This script will not be executed. How can I solve this? I set sieve_dir = ~/sieve This should work, except I misunderstand the doc. # ls -l ./sieve total 6 -rw------- 1 vmail mail 105 Feb 5 09:24 managesieve.sieve -rw------- 1 vmail mail 113 Feb 4 16:30 test.sieve drwx------ 2 vmail mail 512 Feb 5 09:24 tmp Regards, Thomas.

[Dovecot] Problem rebuilding Centos 5/6 pigeonhole RPM from mercurial version
by Juan C. Blanco 12 Feb '14

12 Feb '14

Hi Stephan, I'm traying to rebuild the RH (Centos) EL5 and EL6 RPM with the last mercurial pigeonhole 0.4.2 version, but I'm having problems with the build. I think that I've isolated the problem outside rpmbuild context. I've downloaded dovecot and pigeonhole mercurial versions and built dovecot with the commands: dovecot-2.2.10$ ./autogen.sh dovecot-2.2.10$ ./configure INSTALL_DATA="install -c -p -m644" --enable-header-install --disable-static --with-nss --with-shadow --with-pam --with-gssapi=plugin --with-ldap=plugin --with-sql=plugin --with-mysql --with-zlib --with-sql-drivers --with-libcap --with-db --with-ssl=openssl --with-ssldir=/etc/pki/dovecot --with-notify=inotify --with-solr --with-docs dovecot-2.2.10$ make dovecot-2.2.10$ make install DESTDIR=/var/tmp/dovecot after that, building pigeonhole with the commands pigeonhole-0.4.2$ ./autogen.sh pigeonhole-0.4.2$ ./configure INSTALL_DATA="install -c -p -m644" --build=x86_64-redhat-linux-gnu --host=x86_64-redhat-linux-gnu

pigeonhole-0.4.2$ make pigeonhole-0.4.2$ make install DESTDIR=/var/tmp/dovecot works fine, but if I install pigeonhole in a different path, i.e. pigeonhole-0.4.2$ make install DESTDIR=/var/tmp/pigeonhole I get the following error make[4]: Entering directory `/home/jc/pigeonhole-0.4.2/src/lib-sieve' make[4]: Nothing to be done for `install-exec-am'. test -z

[Dovecot] RFC 5267 Contexts for IMAP4 PARTIAL results
by Anders Thøgersen 11 Feb '14

11 Feb '14

Hello, I am looking at PARTIAL responses using a dovecot version 2.2.5 and am running into an inconsistency with the RFC which I would like to ask about. The following section http://tools.ietf.org/html/rfc5267#section-4.4 lists client requests and server responses which I have tried running against a folder, specifying the ranges that fit the contents of the folder I have selected. The Last of the listed client requests returns a response that is not as I would expect: C: A04 UID SEARCH RETURN (PARTIAL 24000:24500) UNDELETED UNKEYWORD $Junk should return S: * ESEARCH (TAG "A04") UID PARTIAL (24000:24500 NIL) // No results are present, this is beyond the end of the results. S: A04 OK Completed. according to the RFC, but instead of NIL in the PARTIAL result I see the full range of UIDs that are in the folder, as in: C: A02 UID SEARCH RETURN (PARTIAL 23500:24000) UNDELETED S: * ESEARCH (TAG "A02") UID PARTIAL (23500:24000 1:9) S: A02 OK Search completed (0.000 secs). The folder that is selected contains 9 emails with the UIDs 1-9. Should the server return NIL Instead of returning 1:9? Thanks! Anders

[Dovecot] Undertanding what the lmtp_save_to_detail_mailbox actually does
by Alan Chandler 11 Feb '14

11 Feb '14

Hi I am just learning to setup dovecot as part of a project to move my home mail serving from a large and complex linux computer which is acting as internet router/nat gateway to the internet (this leaving me exposed without internet connection when it goes down) to a raspberry pi - which will be port-forwarded to, when I turn my internet cable modem back into a router/modem. I have chosen to try and do this with a Postfix/Dovecot combination with some key user information coming from an sqlite database. Postfix will use Dovecot for authentication (where needed) and use its lmtp service for local delivery. I have so far got Dovecot working fine for the basic stuff, including using rsync to copy each of my users entire maildir from the old machine to the new to prove that it can be accessed. but I have one last specific piece of functionality I want to achieve that the old system does (and has been doing) for at least 5 years (that is what is still online - I think I have "archived" some older stuff). The existing environment uses a Exim4/Cyrus IMAP combination and with Exim I have managed to develop the rules so that all outgoing mail from my internal clients is copied into a subdirectory of their sent mail folder. The format of the folder is Sent.yyyy.mm where yyyy and mm are computed on the fly from todays date. (the .separator defining a subfolder in the hierarchy) I now have several years of saved messages in my existing system. Postfix has nowhere near the flexibility of Exim to develop rules like that, but I think I could potentially use an sql query on my user database to set up a sender_bcc_map that addressed the result to <sender local part>+Sent.<yyyy>.<mm> (or maybe<senderlocalpart>+Sent/<yyyy>/<mm> and then send that to dovecot. I have then to decide how to handle it. The problem I am facing is I can find no documentation about what lmtp_save_to_detail_mailbox actually causes lmtp to actually do. Searching the wiki refers to it only in the LMTP page. How should the detail of the address be formatted to specify a subdirectory - can it be specified even? Should I be using it? I have seen comments in the past about people recommending using sieve for this sort of thing. and indeed it might be better if I could figure it out, in that 1) I could then send to something more simple like <senderlocalpart>+saveoutgoing and use the "date" extension of sieve to generate the split. 2) Users could ultimately decide what to do them selves with this tag (and I could define a global "after_sieve" to throw it away. Unfortunately my reading of the fileinto extension is that the destination can only be a literal string and not a "computed" value based on the date. UNLESS anyone knows different? I would welcome any advice anyone could give me Thanks Alan Chandler

[Dovecot] Sieve - Not showing new emails in Thunderbird?
by craig.dovecot＠noboost.org 11 Feb '14

11 Feb '14

Hi, Issue: Sieve works perfectly and does deliver the mail to the correct mail directories. However Thunderbird doesn't detect the new email, until the user clicks on the folder and then all of a sudden it shows the newly detected emails. Perhaps this is a task for the Thunderbird forums? (Thunderbird 24.2.0) Server Side: * CentOS release 6.3 (Final) * dovecot-2.0.9-7.el6.x86_64 * dovecot-pigeonhole-2.0.9-7.el6.x86_64 * postfix-2.6.6-2.2.el6_1.x86_64 * Server Sieve Settings: mail_location = maildir:~/Maildir plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_vacation_default_period = 10d sieve_vacation_max_period = 30d sieve_vacation_min_period = 1h } * Client App: - Thunderbird 24.2.0 * Userlevel config; File: ~/.dovecot.sieve require "fileinto"; if address :is "to" "sysadmin(a)example.com" { fileinto "sysadmin"; } elsif address :is "to" "root@" { fileinto "sysadmin"; } elsif address :is "from" "root@" { fileinto "sysadmin"; } cya Craig

[Dovecot] Looking for HowTo Postifx, Dovecot and PostgreSQL
by Frank Lanitz 10 Feb '14

10 Feb '14

Hi folks, I know it's a bit a n00bish question, but I'm a little confused about this many different ways on setting up dovecot with postfix and using a PostgreSQL backend for virtual hosts. I've found this one quiet helpful: http://wiki2.dovecot.org/HowTo/DovecotPostgresql even it seems to be little outdated for recent versions of dovecot (the auth part of dovecot.conf). Also its lagging some inforamtions I wasn't able to find on my own (e.g. how to set password for a imap account). Can somebody give me a hint for a up-2-date howto for some noob as I am? Cheers, Frank

[Dovecot] Dsync Errors
by Asai 08 Feb '14

Greetings, I've seen something like this in another thread, about a month ago, but we're running into this error pretty frequently when we run dsync backup. Error: Raw backtrace: /usr/lib64/dovecot/libdovecot.so.0 [0x39ccc5f1c0] -> /usr/lib64/dovecot/libdovecot.so.0(default_fatal_handler+0x35) [0x39ccc5f2a5] -> /usr/lib64/dovecot/libdovecot.so.0 [0x39ccc5ebb3] -> dsync(dsync_brain_mailbox_tree_sync_change+0x41c) [0x42cc0c] -> dsync(dsync_brain_recv_mailbox_tree_deletes+0x10a) [0x42be7a] -> dsync(dsync_brain_run+0x4fc) [0x429cdc] -> dsync [0x42885b] -> dsync [0x4119ff] -> dsync(doveadm_mail_try_run+0x269) [0x411e09] -> dsync(main+0x358) [0x41a2c8] -> /lib64/libc.so.6(__libc_start_main+0xf4) [0x3f4281d994] -> dsync [0x4111c9] We're running Dovecot 2.2.4 and the dsync command is this: dsync -u <username> backup maildir:/mnt/backups/<period>/<domain>/<username> When this happens to a particular users account I delete the backup and let it rebuild, which works for awhile, but then it happens again, and it seems to happen to particular users. Can you point me in the right direction to start troubleshooting this? Thanks. -- --Asai

[Dovecot] Auth socket can't listen using ssl
by Anthony Bourguignon 07 Feb '14

07 Feb '14

Hi, I'm using Dovecot 2.2.9 (debian package on testing). It seems that it's not possible to open an auth socket using ssl. I'm using this configuration : service auth { [...] inet_listener authxmpp-client { address = [ips] port = 5220 } inet_listener genericauth-client { ssl = yes address = [ips] port = 5221 } [...] } Both ports are running fine. But the 5221, which should listen in ssl (because of the "ssl = yes" as written in the documentation here : http://wiki2.dovecot.org/Services ) is using plaintext. If I telnet directly to it, the content is delivered on an unsecured socket. Is there a way to make ssl works on this kind of socket ? Thanks a lot

[Dovecot] Multiple ssl-certs on different ports with the same protocol
by myleetlist＠gmx.de 07 Feb '14

07 Feb '14

Hi, is it possible to use multiple ssl-certs on different _ports_ with the same protocol? I know I can configure multiple certs with the "local <ip>" setting*. But how is this (or similar) possible in v2.2.10: local :100 { protocol imap { ... } } local :101 { protocol imap { ... } } This would be useful in a loadbalancing setup, you don't waste IPs and the config files on different servers stay the same. * [http://wiki2.dovecot.org/SSL/DovecotConfiguration]

[Dovecot] Plugin architecture
by Philipp Brüll 06 Feb '14

06 Feb '14

Hi, I'm currently developing a scrambler plugin which should be used to store the mails encrypted on the disk. It uses a special ostream for encryption and an istream for decryption. The idea is, that if a mail arrives via LMTP it goes through the ostream and is written encrypted to disk. If an mail is accessed via IMAP, the istream is used to decrypt the data from disk. That all works fine, but if I add the zlib plugin it all gets mixed up. For some reason, the lmtp process tries to read something from disk using the chain of istreams. That behaviour is a little bit bizzare to me, because my understanding is, that the zlib plugin at this point should only write (compressed) data to disk. Why is the istream used here? And what is read? If I remove zlib from the configuration again, it all works as expected. The dovecot version is 2.1.17. Best regards, Philipp

[Dovecot] Trying to get Dovecot Director Proxying working
by Murray Trainer 06 Feb '14

Hi All, Firstly, thanks for all the really helpful responses to my previous questions "Architecture for large Dovecot cluster" and "Sizing MTA servers". I am now trying to get a Dovecot director proxy working with a single backend mail server. When I try to connect to the dovecot proxy on the pop3 and imap ports I get connection refused. I want the authentication to be on the backend mail server initially. I am not sure if I am missing something? More info below...

[Dovecot] LMTP troubles
by Phillip Odam 06 Feb '14

06 Feb '14

Background: Dovecot: v 2.0.9 OS: AWS Linux (derived from CentOS) At this stage I've avoided upgrading to a newer version of Dovecot as version 2.0.9 is what AWS Linux provides and I'd like to be able to run a regular AWS Linux installation if I can. As opposed to pulling newer versions of dovecot from other repositories or building from source, since the odds are this issue is not a bug in dovecot. I've just tried setting up the LMTP service and eventually uncovered that that the greeting the server responds with straight after connecting isn't being returned. This must be a configuration mistake on my behalf but I just haven't been able to figure it out yet. I haven't had LMTP configured for awhile but I'm sure I've had it all in place and don't recall any issue like this. I've followed the detail here http://wiki2.dovecot.org/LMTP, in particular # add lmtp to protocols, otherwise its listeners are ignored protocols = imap pop3 lmtp service lmtp { inet_listener lmtp { address = 192.168.0.24 127.0.0.1 ::1 port = 24 } unix_listener lmtp { #mode = 0666 } } What's also interesting, using telnet my first attempt to connect results in the server closing the connection immediately and then a second attempt to connect results in an established connection but no response from the server so that then the LMTP client knows it's all good to begin issuing commands. I have no idea about the architecture of dovecot and the LMTP service but it's as if dovecot has successfully bound to the port allocated for LMTP* but the the LMTP service has either not started or dovecot doesn't know which service to pass the connection on to. * - dovecot has definitely bound to the port (localhost:24) as netstat clearly shows this. I've tried enabling debug logging per the details here http://wiki2.dovecot.org/Logging and checked that I'm looking at all the logs I need to be using doveadm log find but not seeing any information that helps. At the moment I know I'm light on necessary detail for anyone to help but I thought I'd try in case anyone has seen this before and is able to tell me I've missed X and Y. I'm planning on setting up a clean environment to sort this issue out and if needed will follow up here with more detail and the final solution/s. Thanks Phillip

[Dovecot] mime support for pigeonhole

is there any chance of rfc5703 (mime support/extension) being added to pigeonhole? I am trying to filter mail with .exe and .zip attachments, to no success.

I am not sure I understood this issue correctly... When using maildir with ie ldap. Suppose ldap attribute settings say gid 8 and uid 999, Those are the permissions for every email address. If so, someone who has access to one email user on the server, has access to all. If this is so, is using mailbox instead of maildir resolve this problem? Thanks in advance

[Dovecot] userdb section not recognized in dovecot.conf. Help?
by CypherPunk 06 Feb '14

06 Feb '14

I'm following a tutorial[1] on how to configure dovecot and the tutorial says to insert the following configuration options into the dovecot.conf file: disable_plaintext_auth = no mail_privileged_group = mail mail_location = mbox:~/mail:INBOX=/var/mail/%u userdb { driver = passwd } This seems to have worked for a lot of others using this tutorial but not for me. When I try to start dovecot, I am told that the section at userdb is an unknown section type. I've spent the last few hours on Google searching this out and I've gotten conflicting answers that don't make sense. Is this the proper way to use the userdb directive? For information, I've also tried userdb{ driver = passwd-file } and that didn't work either. So I'm assuming that perhaps userdb is deprecated somehow but I don't know what to replace it with. Can someone point me in the right direction? Many Thanks! CypherPunk [1] https://www.digitalocean.com/community/articles/how-to-set-up-a-postfix-e-m…

[Dovecot] Debian Wheezy-Backports - Dovecot (1:2.2.9-1~bpo70+1) missing xz compression support?

Hallo Everyone, since some days a new dovecot version is available in Debian "wheezy-backports": (1:2.2.9-1~bpo70+1) wheezy-backports As described in http://wiki2.dovecot.org/Plugins/Zlib and http://www.dovecot.org/doc/NEWS-2.2 "xz"-compression is available since Dovecot version 2.2.9. Today I tried to convert my mailboxes with the new xz compression. Therfore I changed my config as follows: /etc/dovecot/conf.d/10-mail.conf: # Space separated list of plugins to load for all services. Plugins specific to IMAP, LDA, etc. are added to this list in their own .conf files. mail_plugins = zlib acl fts fts_solr /etc/dovecot/conf.d/90-plugin.conf: # Enable these only if you want compression while saving: zlib_save_level = 9 # 1..9 zlib_save = xz # gz or bz2 or xy Now I tried to convert my mailboxes - but somehow, something goes wrong: root@SERVER:/# dovecot --version 2.2.9 root@SERVER:/# dsync mirror mdbox:/srv/converted_vmail/ doveadm(root): Error: zlib_save: Support not compiled in for handler: xz dsync(root): Error: zlib_save: Support not compiled in for handler: xz Where is the failure? Did the packet maintainer forget to activate xz? I can't find anything xz related in the debian package changelog: http://metadata.ftp-master.debian.org/changelogs//main/d/dovecot/dovecot_2.… Should I contact the Debian packet maintainer? http://packages.qa.debian.org/d/dovecot.html Best regards T.B.

[Dovecot] Applying a DNS RBL to deny authentication?
by Marc Perkel 05 Feb '14

05 Feb '14

Hope to get some attention about this idea to reduce hacking passwords. Here is a list of about 700,000 IP addresses that are hacking passwords through SMTP AUTH http://ipadmin.junkemailfilter.com/auth-hack.txt This is a list of IP addresses that attempted to authenticate against my fake AUTH advertizing on servers with no authentication. We do front end spam filtering for thousands of domains and I decided to advertize authentication where there is none and I accept and blackhole all authenticated email to those servers. I have harvested the IP addresses in this list that is available through an RBL. It seems to me that a nice dovecot feature would be the ability to do a black list check against IP addresses connecting and deny access if listed. Thoughts?

The following just causes each msg file in maildir to be compressed as well. dsync -f -u user1 backup maildir:/var/tmp/user1 While this just causes the dsync to fail while spewing a bunch of errors because it can no longer read the compressed mdbox files. dsync -f -u user1 -o mail_plugins= backup maildir:/var/tmp/user1 # doveconf -n # 2.2.4: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-279.19.1.el6.x86_64 x86_64 CentOS release 6.3 (Final) auth_debug = yes auth_debug_passwords = yes auth_default_realm = domain1.net auth_master_user_separator = * auth_mechanisms = plain login auth_verbose = yes auth_verbose_passwords = plain debug_log_path = /var/log/dovecot-debug.log disable_plaintext_auth = no dotlock_use_excl = no lda_mailbox_autocreate = yes lock_method = dotlock mail_access_groups = mail mail_debug = yes mail_fsync = always mail_location = mdbox:~/mail:INDEX=~/index mail_plugins = quota zlib mail_privileged_group = mail 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 mbox_read_locks = dotlock mbox_write_locks = dotlock mdbox_rotate_interval = 1 weeks mdbox_rotate_size = 20 M mmap_disable = yes namespace { inbox = yes location = mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Junk { auto = subscribe special_use = \Junk } mailbox Sent { auto = subscribe special_use = \Sent } mailbox Trash { auto = subscribe special_use = \Trash } prefix = separator = / type = private } passdb { args = /etc/dovecot/dovecot-sql-master.conf.ext driver = sql master = yes pass = yes } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { autosubscribe = Trash autosubscribe2 = Junk autosubscribe3 = Drafts autosubscribe4 = Sent autosubscribe5 = INBOX mail_max_userip_connections = 10 managesieve_max_line_length = 65536 quota = dict:User quota::file:%h/dovecot.quota quota2_rule = Trash:storage=+10%% quota3_rule = Junk:storage=+20%% quota_rule = *:storage=100M:messages=100000 recipient_delimiter = + sieve_before = /var/opt/mail/global.sieve/ zlib_save = gz zlib_save_level = 9 } pop3_reuse_xuidl = yes protocols = imap pop3 sieve lmtp service auth { inet_listener auth { port = 113 } unix_listener auth-userdb { user = nobody } } service lmtp { inet_listener lmtp { port = 24 } process_min_avail = 10 service_count = 1 } service managesieve-login { inet_listener sieve { port = 4190 } process_min_avail = 0 service_count = 1 vsz_limit = 64 M } ssl = no ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } protocol lda { mail_plugins = quota zlib sieve } protocol imap { mail_plugins = quota zlib imap_quota } protocol sieve { mail_max_userip_connections = 10 mail_plugins = quota zlib managesieve_max_line_length = 65536 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 } protocol lmtp { mail_plugins = quota zlib sieve }

[Dovecot] BLF-CRYPT passwords
by KT Walrus 04 Feb '14

04 Feb '14

I’m using the Dovecot Enterprise Edition on Centos 6.5, but Blowfish password hashes don’t seem to work. What can I do to enable Blowfish hashes for passwords? Maybe I don’t have my installation configured properly? Note that I really want to use the existing Blowfish hashes in my MySQL database for Dovecot Authentication. The hashes are generated by PHP crypt() that has Blowfish support built-in. I looked at PHP’s sources, and PHP uses crypt_blowfish.c from http://www.openwall.com/crypt/. This code is in the public domain and could easily be used by Dovecot to support Blowfish passwords on all platforms (if Dovecot doesn’t already support Blowfish on all platforms). Kevin

[Dovecot] mail_log_events, but who exactly triggered events?
by Arkadiusz Miśkiewicz 04 Feb '14

04 Feb '14

Hi. mail_log_events is nice addition but how to log who exactly triggered particular event? For example 5 users from 5 IP addresses uses single imap user/mailbox. One of them deletes email and I'm logging delete related events. The only logged thing is: dovecot: imap(user): delete: box=INBOX, uid=673287, msgid=<some@thing>, size=1230 which tells me nothing about who triggered it actually (note all 5 users were logged in at deletion time) How to solve this problem? Thanks, -- Arkadiusz Miśkiewicz, arekm / maven.pl

[Dovecot] zlib unexpected EOF
by Anand Kumria 04 Feb '14

04 Feb '14

Hi, I am seeing occasional log entries like: Feb 4 06:20:01 mail1 dovecot: imap(user(a)example.com): Error: read(<imap client>) failed: zlib.read(<imap client>): unexpected EOF at 894774 Feb 4 06:20:01 mail1 dovecot: imap(user(a)example.com): Disconnected in APPEND (1 msgs, 201 secs, 0/5180550 bytes) in=894774 out=643701 I've been able to correlate this to users - using Thunderbird - complaining that they have been unable to "send email". Is the problem on the Dovecot side, their side or something else? If on the Dovecot any pointers and what I should look at? Thanks, Anand

Hello! I need to configure Quota on Roundcubemail with Dovecot2. So, I did: 90-quota.conf: # SQL backend: quota = dict:User quota::proxy::sqlquota quota_rule = *:storage=20M:messages=1000 } dict { sqlquota = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } OK, works! but, My webmail shows me 20M of quota. But on my Postfixadmin I configured 200M. How can I fix this? Att; *Lucas Possamai* http://about.me/lucaspossamai https://www.digitalocean.com/?refcode=25021cb7dbdf

[Dovecot] Assertion failed with imapc after upgrading Dovecot from 2.1.7 to 2.2.9
by Sylvain 29 Jan '14

29 Jan '14

Hi ! I have an old Courier IMAP and in front of it, I have put a proxy cache with Dovecot/imapc. I use Debian Wheezy (stable) which package Dovecot in version 2.1.7. I have tested the upgrade to Debian Jessie (testing) which package Dovecot in version 2.2.9 but an assertion is thrown : dovecot: imap(xxx): Panic: file imapc-list.c: line 499 (imapc_list_delete_unused_indexes): assertion failed: (strncmp(vname, fs_list->ns->prefix, fs_list->ns->prefix_len) == 0) I have checked source code and have seen that if *imapc_list_prefix* is not set, assertion will not be "walked". It's works but special inbox aren't detected correctly in email clients. If I understand the meaning of *vname* variable, it is because our Courier IMAP send us "INBOX" which is the value of my *imapc_list_prefix* and thus, assertion is thrown.

[Dovecot] Shared mailbox ACL
by Alex Ferrara 29 Jan '14

29 Jan '14

Hi everyone, I am having some trouble with shared folders in trying to replicate how we use them with a Cyrus backend. The auth database is Samba4 active directory, so I am using an LDAP lookup to authenticate and forcing the UID and GID to be all the same. I have a post-login script that sets the group ACL, and this seems to be working fine. /mnt/mail is an NFS mount to a FreeNAS machine, and there is only one Dovecot server connecting to that NFS share. I have been able to get the inbox of the shared mailbox to appear in Thunderbird, but I would like to allow all subfolders to have the same ACLs. Is there a way to do this without having an ACL entry for each folder in the dovecot-acl file? I also cannot seem to create folders under the shared inbox. Thanks. Below is the output of /mnt/mail/acl/shared-mailboxes shared/shared-boxes/group/accounting/accounting 1 shared/shared-boxes/group/team1/team1 1 shared/shared-boxes/group/team2/team2 1 Below is the output of dovecot -n # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-22-pve x86_64 Debian 7.3 nfs auth_mechanisms = plain login auth_username_format = %n mail_debug = yes mail_location = maildir:/mnt/mail/mailboxes/%n/Maildir:INDEX=/var/local/dovecot-indexes/%n mail_plugins = acl mail_shared_explicit_inbox = no managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave namespace { list = yes location = maildir:/mnt/mail/mailboxes/%%n/Maildir:INDEX=/var/local/dovecot-shared/%%n prefix = ZGroup/%%n/ separator = / subscriptions = no type = shared } namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = separator = / type = private } passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { acl = vfile acl_defaults_from_inbox = yes acl_shared_dict = file:/mnt/mail/acl/shared-mailboxes sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = " imap lmtp sieve" service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } } service imap-postlogin { executable = script-login /usr/local/bin/postlogin.py user = vmail } service imap { executable = imap imap-postlogin } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } user = vmail } ssl_cert = </etc/dovecot/dovecot.pem ssl_key = </etc/dovecot/private/dovecot.pem userdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } protocol lmtp { mail_plugins = quota sieve } protocol lda { mail_plugins = quota sieve } protocol imap { mail_plugins = acl imap_acl }

Oh yes, that's right. I confused maildir format with sendmail queue files that separates header and body. There is still some similarlity for mass mailouts to the same mail domain: they will have almost identical headers +/- message IDs and a few bytes here and there, but as you say, SiS is the way to go for deduping bulky message attachments.

[Dovecot] recipient_delimiter -- feature request
by Andrew Ray 29 Jan '14

29 Jan '14

Hi, It would be nice if the recipient_delimiter configuration option supported multiple recipient delimiters as Postfix now does. e.g. now if I set: recipient_delimiter = +- in Postfix, then test-extension(a)sample.com and test+extension(a)sample.com are both recognized. But if I set: recipient_delimiter = +- in Dovecot, neither of the above are recognized and instead test+-extension(a)sample.com is valid. Well, presently this feature isn't that important to me, but I imagine it could be a source of confusion for people who are migrating from say qmail to postfix (as I am doing) and notice Postfix's cool ability to support both types of delimiters and assume Dovecot will as well (as I did).

[Dovecot] post-login scripting failing with "denied access to user" v2.1.7
by Frank 29 Jan '14

29 Jan '14

I am trying to have a default sieve rule for new mailboxes that can be edited by users using the round cube sieve plugin. It would actually be better executed when a new user is created but my postfixadmin runs on a separate machine so that's a bit tricky. The "sieve-default =" setting won't quite achieve what I want as I want users to be able to edit the default rule (to adjust SPAM level) Mail works fine before I add my post-login script to 10-master.conf ---------------------- service imap { # tell imap to do post-login lookup using a socket called "imap-postlogin" executable = imap imap-postlogin } service imap-postlogin { # all post-login scripts are executed via script-login binary executable = script-login /etc/dovecot/custom_sieve/postlogin.sh # the script process runs as the user specified here (v2.0.14+): user = mail # also tried $default_internal_user and root # this UNIX socket listener must use the same name as given to imap executable unix_listener imap-postlogin { } } After adding this setting, login fails and gives the error below. It certainly looks like a permission issue, but I have checked my script is executable and owned by vmail:vmail. The bash script executes fine as the mail user. The other possibility is that dovecot is denying access to the $HOME variable, but that seems unlikely. Nevertheless, I am stuck!

Just a guess, but I expect the difference is because NetApp de-dupes by checksumming blocks and mark whole blocks as duplicates if they have the same checksum. The message body has the same block offset in maildir (i.e. the start of a message is at byte 0), whereas mdbox might align message body anywhere in a block, so you might have 512 different block configurations for the same message. I don't know whether message alignment would be a worthwhile optimization for mdbox. Joseph Tam <jtam.home(a)gmail.com>

Everything costs less than a NetApp...except an EMC. > If anyone has any first-hand experience (or even > off-the-top-of-their-head thoughts), I'd love to hear them) Distributed filesystems give you the advantage of a single filesystem namespace with massive amounts of storage, fairly easy addition of storage space, and distributed replication to allow failure of a storage node without service interruption. Replication mitigates node failure, but not disk failure, so you still need RAID in each node. So you have RAID6 in a node and filesystem block mirroring amongst nodes. Thus storage utilization is -worse- than direct attach, CFS on SAN, or NFS head attached RAID10 and far worse than RAID6 in these 3 setups. And if using large SSD cache you'd surely use RAID6 with DAS, CFS, or NFS. You'd need half as many disk drives vs DFS. Each DFS expansion, assuming the typical model, entails the cost of a server, RAID HBA (unless using md) and disks, not strictly buying disks as with DAS, CFS/SAN, or NFS filer. Then you also need more switch ports, more power connections, greater UPS capacity due to all the CPUs, RAM, etc in the nodes. And you'll have a higher electric bill. So while a distributed filesystem storage architecture may seem less expensive it may not be. And just as one can build a DIY DFS cluster, one can also build a DIY NFS cluster instead of buying a NetApp, saving significant cash on the front end box and on disks since you'd need half as many vs a distributed filesystem architecture, though failure of one node may not be quite as graceful as with a NetApp losing a controller board. -- Stan

[Dovecot] Replication - what am I doing wrong?
by IT geek 31 27 Jan '14

27 Jan '14

Hi, I'm having issues getting replication working, and I'm not also not having much luck finding help on it. So I'm wondering... am I not asking the right questions? Or am I not providing enough information... or do we just not know how this aspect of the technology works? If it's the former, then any pointers on what questions to ask or information to provide would be very helpful. If the community genuinely doesn't know how this works then that's okay too - I will look at another solution (if one exists) and try to move on. But if I can get this working then that would be amazing as I really like Dovecot and would be gutted to move away from it. -Mark

This is the error i'm always getting when my client tries to get new mails, which i want to get rid off: http://sprunge.us/NZhf Jan 25 11:49:30 old dovecot: auth-worker(15979): Debug: sql(root(a)hallowe.lt,81.217.212.85): query: SELECT password FROM mailbox WHERE username = 'root(a)hallowe.lt' Jan 25 11:49:30 old dovecot: auth: Debug: client out: OK#0111#011user=root(a)hallowe.lt Jan 25 11:49:30 old dovecot: auth-worker(15979): Debug: sql(root(a)hallowe.lt,81.217.212.85): SELECT CONCAT('maildir:/var/vmail/',maildir) AS mail, 1000 AS uid, 1000 AS gid FROM mailbox WHERE username = 'root(a)hallowe.lt' Jan 25 11:49:30 old dovecot: auth: Debug: master out: USER#0113983671297#011root@hallowe.lt#011mail=maildir:/var/vmail/hallowe.lt/root/#011uid=1000#011gid=1000 Jan 25 11:49:30 old dovecot: imap-login: Login: user=<root(a)hallowe.lt>, method=PLAIN, rip=81.217.212.85, lip=10.111.56.107, mpid=17606, TLS, session=<rQGqOsnwuABR2dRV> Jan 25 11:49:30 old dovecot: imap(root(a)hallowe.lt): Debug: Effective uid=1000, gid=1000, home= Jan 25 11:49:30 old dovecot: imap(root(a)hallowe.lt): Debug: quota: No quota setting - plugin disabled Jan 25 11:49:30 old dovecot: imap(root(a)hallowe.lt): Debug: maildir++: root=/var/vmail/hallowe.lt/root, index=, control=, inbox=/var/vmail/hallowe.lt/root, alt= Jan 25 11:49:30 old dovecot: imap(root(a)hallowe.lt): Panic: file index-mailbox-check.c: line 75 (index_mailbox_check_add): assertion failed: (box->notify_min_interval > 0) Jan 25 11:49:30 old dovecot: imap(root(a)hallowe.lt): Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(+0x4414a) [0x7f858118714a] -> /usr/lib/dovecot/libdovecot.so.0(+0x4418e) [0x7f858118718e] -> /usr/lib/dovecot/libdovecot.so.0(i_fatal+0) [0x7f858115e82a] -> /usr/lib/dovecot/libdovecot-storage.so.0(+0x99027) [0x7f858146b027] -> /usr/lib/dovecot/libdovecot-storage.so.0(+0x4ccc9) [0x7f858141ecc9] -> dovecot/imap(cmd_idle+0x66) [0x7f8581907c96] -> dovecot/imap(command_exec+0x3c) [0x7f858190dedc] -> dovecot/imap(+0x11f2e) [0x7f858190cf2e] -> dovecot/imap(+0x11fda) [0x7f858190cfda] -> dovecot/imap(client_handle_input+0x11d) [0x7f858190d23d] -> dovecot/imap(client_input+0x65) [0x7f858190db35] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x36) [0x7f8581194016] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0xa7) [0x7f8581194cc7] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_run+0x28) [0x7f8581193a28] -> /usr/lib/dovecot/libdovecot.so.0(master_service_run+0x13) [0x7f8581180483] -> dovecot/imap(main+0x297) [0x7f85819053e7] -> /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xfd) [0x7f8580dd7ead] -> dovecot/imap(+0xa561) [0x7f8581905561] Jan 25 11:49:30 old dovecot: imap(root(a)hallowe.lt): Fatal: master: service(imap): child 17606 killed with signal 6 (core dumps disabled) I asked for this in the irc already but got no answer.

[Dovecot] outlook will not sync
by Eric Broch 27 Jan '14

27 Jan '14

Dovecot users list, I started having problems with Outlook not syncing with Dovecot a public imap folder upon issuing a send/receive in the client; eventually Outlook timed out, and I received the following error in the Dovecot log. Jan 23 09:20:23 imap(user(a)mydom.com): Error: FETCH [] for mailbox projects.myfolder UID 120 got too little data: 7744 vs 7759 Jan 23 09:20:23 imap(user(a)mydom.com): Error: Maildir filename has wrong W value: /home/vpopmail/domains/mydom.com/shared/projects/.myfolder/cur/1384292337.M440452P9788.mail.mydom.com,S=265901,W=269597:2,Sc Jan 23 09:20:23 imap(user(a)mydom.com): Error: Corrupted index cache file /home/vpopmail/domains/mydom.com/shared/projects/.myfolder/dovecot.index.cache: Broken virtual size for mail UID 120 Jan 23 09:20:23 imap(user@mydom): Info: Disconnected: FETCH failed bytes=175/270387 However, I've since removed the file manually, deleted the old folder and recreated it and Outlook will still not sync even in the absence of the above error. Has anyone seen this issue--slow to no Outlook performance with dovecot--before, and/or does anyone have a solution or point me in the right direction? Thanks!

[Dovecot] dovecot produces messages dupes after nfs problems
by Patrick Westenberg 25 Jan '14

25 Jan '14

Hi everyone, some days ago I had trouble with my NFS-Server (high delays) which caused dovecot lmtp to deliver the same message several times (up to 10x). I recognized some old/unused .nfsXXXX files in the maildirs which seemed to be index files. I deleted them and everything was fine again. However, there are still 2-3 mailboxen where mails (old and new ones) are delivered multiple times. All duplicates have no "received from" headers. Seperate lmtp log shows only one delivery. Any hint or advice what might be wrong?

[Dovecot] Architecture for large Dovecot cluster
by Murray Trainer 25 Jan '14

25 Jan '14

Hi All, I am trying to determine whether a mail server cluster based on Dovecot will be capable of supporting 500,000+ mailboxes with about 50,000 IMAP and 5000 active POP3 connections. I have looked at the Dovecot clustering suggestions here: http://blog.dovecot.org/2012/02/dovecot-clustering-with-dsync-based.html and some other Dovecot mailing list threads but I am not sure how many users such a setup will handle. I have a concern about the I/O performance of NFS in the suggested architecture above. One possible option available to us is to split up the mailboxes over multiple clusters with subsets of domains. Is there anyone out there currently running this many users on a Dovecot based mail cluster? Some suggestions or advice on the best way to go would be greatly appreciated. Thanks Murray

hi, i tried to setup my configuration to use the SETQUOTA command but the only thing i got is: 3 setquota "User quota" (storage 12345) 3 OK Setquota completed. but nothing is changed in database. i modified the password_query and the user_query to return the admin and userdb_admin field, both set to y. all other changes that are done are like in the wiki http://wiki2.dovecot.org/Quota/Configuration enabling debug doesn't show anything in debug.log

[Dovecot] Dovecot imap-postlogin failed
by Sayajin 24 Jan '14

24 Jan '14

*** This is 2 posts combined into one which I had asked on linuxquestions.org and never got an answer *** Hi, In short I am trying to run a bash script which will then update a mysql database with the last login date/time & last IP for each mailbox. I have searched google dead but still cant figure out what im doing wrong or if there is some issue with the centos 6 rpm's for dovecot. -- - 1st i had the default dovecot in the centos 6 repo's which is version: 2.0.9 - I read that there was an issue with the script-login binary which was fixed in version 2.0.14, so i updated dovecot to version 2.2.7. - This sadly did not fix my issue with the bash script excecuting. In my /etc/dovecot/conf.d/10-master.conf i have the following service imap { executable = imap imap-postlogin } service imap-postlogin { executable = script-login /var/www/lighttpd/mail-admin/scripts/lastLogin.sh } But when i try login i still get the same error as with the previous version: - Nov 27 14:44:36 dovecot: imap(MaIlBoX(a)DoMaIn.co.za): Error: net_connect_unix(/var/run/dovecot/imap-postlogin) failed: No such file or directory - One thing i did notice on the one site was that someone had a ls of their /var/run/dovecot directory, and in there was a binary called imap-postlogin. - But i dont have that binary anywhere on my server, with the old or new version of dovecot. Please any help would be appreciated. ===================================================== ===================================================== Ok well i tried a few other things and got it working a bit more. So the variables that i needed are now being set correctly etc, but im getting authentication errors now which I was not before. my setup in 10-master.conf now looks like the following: service imap-postlogin { executable = script-login /var/www/lighttpd/mail-admin/scripts/lastLogin.sh unix_listener imap-postlogin { user = root } } service imap { executable = imap imap-postlogin } My lastLogin.sh bash script has the following in it for debugging echo "$(date +%Y.%m.%d-%H:%M:%S)"; echo "User: ${USER}" >> /tmp/tracking.log 2>&1; echo "Home: ${HOME}" >> /tmp/tracking.log 2>&1; echo "Client IP: ${IP}" >> /tmp/tracking.log 2>&1; echo "Server IP: ${LOCAL_IP}" >> /tmp/tracking.log 2>&1; The output to my /tmp/tracker.log is the following User: user(a)domain.com Home: /var/spool/mail/domain.com/user Client IP: x.x.x.x Server IP: y.y.y.y The Authentication Error I am getting now dovecot: auth: Debug: Loading modules from directory: /usr/lib64/dovecot/auth dovecot: auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_mysql.so dovecot: auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_pgsql.so dovecot: auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_sqlite.so dovecot: auth: Debug: Read auth token secret from /var/run/dovecot//auth-token-secret.dat dovecot: auth: Debug: auth client connected (pid=25865) dovecot: auth: Debug: client in: AUTH#0111#011PLAIN#011service=imap#011secured#011session=VPOQpNvsPwDELro2#011lip=X.X.X.X#011rip=Y.Y.

[Dovecot] Writing an FTS plugin
by John Morrissey 23 Jan '14

23 Jan '14

Hi, I'm having some trouble writing an FTS plugin that uses notmuch (http://notmuchmail.org/) as the backend. As a proof of concept, I'm adding a hardcoded UID to the search results in the plugin's lookup handler: seq_range_array_add(&result->definite_uids, 1, 42); but this UID is never returned by IMAP SEARCH commands. I know the plugin is being used, since I'm also syslogging immediately before the call to seq_range_array_add(). Interestingly, SEARCH commands return correct results (based on the mailbox content and the search terms specified), but I'm not sure where those results are coming from. The notmuch plugin is the only configured FTS plugin: mail_plugins = $mail_plugins fts fts_notmuch plugin { fts = notmuch } What might I be doing wrong? Additionally, notmuch returns message filenames, which I'll need to translate to UIDs. I've seen maildir_uidlist_get_uid(), but I'm not sure where to get the struct maildir_uidlist arg it needs. notmuch only supports the Maildir format, so using a maildir_* function seems a reasonably safe assumption, but is there a better way? john -- John Morrissey _o /\ ---- __o jwm(a)horde.net _-< \_ / \ ---- < \, www.horde.net/ __(_)/_(_)________/ \_______(_) /_(_)__

My scheme is: There are several postfix on different machines 1.1.1.1 - domain1 2.2.2.2 - domain2 3.3.3.3 - domain3 All they send messages to one server virtual_transport = lmtp:10.10.10.10:24 where mail is stored. In 10.10.10.10 installed dovecot 2.2.9, dovecot-pigeonhole 0.4.2 and another posfix In postfix inet_interfaces = 10.10.10.10 sender_dependent_relayhost_maps = hash:$config_directory/relayhost_maps relayhost_maps @domain1 [1.1.1.1] @domain2 [2.2.2.2] @domain3 [3.3.3.3] Sieve script make from Roundcube require ["vacation"]; # rule:[autoreply] if true { vacation :days 1 :subject "Test." "Test."; } (if add [":from" string] nothing changes) The letter comes, script fulfills, vacation auto-reply sent. But either /usr/sbin/sendmail -i -f <> -- user@senddomain or, if write in 15-lda.conf submission_host = 10.10.10.10:25 postfix log Jan 1 00:00:00 mail pf-OUT/cleanup[6098]: 4CD104A8A4: message-id=<dovecot-sieve-1390316174-295666-0@mail> Jan 1 00:00:00 mail pf-OUT/qmgr[5950]: 4CD104A8A4: from=<>, size=693, nrcpt=1 (queue active) How to make dovecot and dovecot-pigeonhole write in field MAIL FROM:?

[Dovecot] beginners sieve: copy not move to subfolder?
by voytek＠sbt.net.au 22 Jan '14

22 Jan '14

I'm trying to learn how do basic stuff with sieve; I pasted this from a tutorial, it works fine, mail is delivered to 'friends' BUT, what should I do to keep mail in main inbasket as well as, copy to subbasket ? tried 'copy' but failed so far main_script: line 6: error: unknown command 'copy' (only reported once at first occurence). even after I added 'copy' to 'require' still failed ? ------------------------------------ require ["fileinto", "reject"]; # Daffy Duck is a good friend of mine. if address :is "from" "daffy.duck(a)example.com" { fileinto "friends"; }

[Dovecot] IDLE dropping EXISTS events on mass message arrival
by Eric Wong 22 Jan '14

22 Jan '14

Hi, I'm not sure if this is some throttling/DoS protection or a bug. I didn't see notice anything like it mentioned looking at the NEWS file from hg, this is on 2.1.7 on Debian stable. I have a client doing IDLE on INBOX.vomiteer. When individual messages arrive with some time interval in between them, I get EXISTS events for each message as expected. However, when I store a bunch of messages at once (via tag + mass copy in mutt on a fast-ish connection), I get a few EXISTS events (sometimes one, sometimes two) even though I copied a lot of new messages over. I expected to get an EXISTS event for each message which arrived, but perhaps there's some sort of DoS/throttling mechanism. strace -t -s4096 output of the dovecot process below: fd=13 is inotify, you'll see large read(13, ... indicating multiple filenames from inotify. However, only one EXISTS message got written to the socket. I've filtered out the gettimeofday syscalls for brevity. 07:30:02 epoll_wait(9, {}, 6, 3937) = 0 07:30:06 stat64("/home/ew/.maildir/.INBOX.vomiteer/cur", {st_mode=S_IFDIR|0700, st_size=12288, ...}) = 0 07:30:06 stat64("/home/ew/.maildir/.INBOX.vomiteer/new", {st_mode=S_IFDIR|0700, st_size=4096, ...}) = 0 07:30:06 stat64("/home/ew/.maildir/.INBOX.vomiteer/new", {st_mode=S_IFDIR|0700, st_size=4096, ...}) = 0 07:30:06 stat64("/home/ew/.maildir/.INBOX.vomiteer/cur", {st_mode=S_IFDIR|0700, st_size=12288, ...}) = 0 07:30:06 stat64("/home/ew/.maildir/.INBOX.vomiteer/dovecot.index.log", {st_mode=S_IFREG|0600, st_size=25920, ...}) = 0 07:30:06 fstat64(10, {st_mode=S_IFREG|0600, st_size=25920, ...}) = 0 07:30:06 epoll_wait(9, {}, 6, 7865) = 0 07:30:14 setsockopt(11, SOL_TCP, TCP_CORK, [1], 4) = 0 07:30:14 write(11, "* OK Still here\r\n", 17) = 17 07:30:14 setsockopt(11, SOL_TCP, TCP_CORK, [0], 4) = 0 07:30:14 time(NULL) = 1390289414 07:30:14 epoll_wait(9, {{EPOLLIN, {u32=4159555408, u64=4159555408}}}, 6, 22124) = 1 07:30:17 read(13, "\2\0\0\0\200\0\0\0\t\365\r\0000\0\0\0001390289417.M94623P14841.dcvr,S=1580,W=1619:2,S\0\0\2\0\0\0\200\0\0\0\n\365\r\0000\0\0\0001390289417.M94624P14841.dcvr,S=1580,W=1619:2,S\0\0\2\0\0\0\200\0\0\0\v\365\r\0000\0\0\0001390289417.M94625P14841.dcvr,S=1422,W=1460:2,S\0\0\2\0\0\0\200\0\0\0\f\365\r\0000\0\0\0001390289417.M94626P14841.dcvr,S=1422,W=1460:2,S\0\0\2\0\0\0\200\0\0\0\r\365\r\0000\0\0\0001390289417.M94627P14841.dcvr,S=1861,W=1907:2,S\0\0\2\0\0\0\200\0\0\0\16\365\r\0000\0\0\0001390289417.M94628P14841.dcvr,S=1861,W=1907:2,S\0\0\2\0\0\0\200\0\0\0\17\365\r\0000\0\0\0001390289417.M94629P14841.dcvr,S=4732,W=4854:2,S\0\0\2\0\0\0\200\0\0\0\20\365\r\0000\0\0\0001390289417.M94630P14841.dcvr,S=4732,W=4854:2,S\0\0\2\0\0\0\200\0\0\0\21\365\r\0000\0\0\0001390289417.M94631P14841.dcvr,S=4028,W=4128:2,S\0\0\2\0\0\0\200\0\0\0\22\365\r\0000\0\0\0001390289417.M94632P14841.dcvr,S=4028,W=4128:2,S\0\0\2\0\0\0\200\0\0\0\23\365\r\0000\0\0\0001390289417.M94633P14841.dcvr,S=3865,W=3968:2,S\0\0\2\0\0\0\200\0\0\0\24\365\r\0000\0\0\0001390289417.M94634P14841.dcvr,S=3865,W=3968:2,S\0\0", 32768) = 768 07:30:17 epoll_wait(9, {{EPOLLIN, {u32=4159555408, u64=4159555408}}}, 6, 499) = 1 07:30:17 read(13, "\2\0\0\0\200\0\0\0\25\365\r\0000\0\0\0001390289417.M94635P14841.dcvr,S=4092,W=4189:2,S\0\0\2\0\0\0\200\0\0\0\26\365\r\0000\0\0\0001390289417.M94636P14841.dcvr,S=4092,W=4189:2,S\0\0\2\0\0\0\200\0\0\0\27\365\r\0000\0\0\0001390289417.M94637P14841.dcvr,S=1517,W=1552:2,S\0\0\2\0\0\0\200\0\0\0\30\365\r\0000\0\0\0001390289417.M94638P14841.dcvr,S=1517,W=1552:2,S\0\0", 32768) = 256 07:30:17 epoll_wait(9, {}, 6, 498) = 0 07:30:17 stat64("/home/ew/.maildir/.INBOX.vomiteer/new", {st_mode=S_IFDIR|0700, st_size=4096, ...}) = 0 07:30:17 stat64("/home/ew/.maildir/.INBOX.vomiteer/cur", {st_mode=S_IFDIR|0700, st_size=12288, ...}) = 0 07:30:17 stat64("/home/ew/.maildir/.INBOX.vomiteer/dovecot.index.log", {st_mode=S_IFREG|0600, st_size=26328, ...}) = 0 07:30:17 fstat64(10, {st_mode=S_IFREG|0600, st_size=26328, ...}) = 0 07:30:17 pread64(10, "\200\200\200\207@\0\0\20\0\0\0\0\0\0\0\0$\0\0\0\0\0\0\0\1\0\0\0\200\200\200\214\0\1\0\20\0\0$\0\337!\336R\344\231\2L\0\0\0\0\t\"\336R\t\"\336R\0\0\0\0\t\"\336R\0\0\0\0007\n\0\0\200\200\200\204 \0\0\20@\0\4\0\234e\0\0\200\200\200\242\2\0\0\20\317\0\0\0\10\0\0\0\320\0\0\0\10\0\0\0\321\0\0\0\10\0\0\0\322\0\0\0\10\0\0\0\323\0\0\0\10\0\0\0\324\0\0\0\10\0\0\0\325\0\0\0\10\0\0\0\326\0\0\0\10\0\0\0\327\0\0\0\10\0\0\0\330\0\0\0\10\0\0\0\331\0\0\0\10\0\0\0\332\0\0\0\10\0\0\0\333\0\0\0\10\0\0\0\334\0\0\0\10\0\0\0\335\0\0\0\10\0\0\0\336\0\0\0\10\0\0\0\200\200\200\207@\0\0\20\1\0\0\0\0\260\2L\0\0\0\0\4\0\4\0\1\0\0\0\200\200\200\242\0\2\0\20\317\0\0\0\250\275\0\0\320\0\0\0\234\277\0\0\321\0\0\0|\301\0\0\322\0\0\0|\304\0\0\323\0\0\0\200\307\0\0\324\0\0\0|\312\0\0\325\0\0\0h\315\0\0\326\0\0\0\\\320\0\0\327\0\0\0\224\323\0\0\330\0\0\0\210\325\0\0\331\0\0\0h\327\0\0\332\0\0\0h\332\0\0\333\0\0\0l\335\0\0\334\0\0\0h\340\0\0\335\0\0\0T\343\0\0\336\0\0\0H\346\0\0\200\200\200\204 \0\0\0200\0\4\0\337\0\0\0", 8192, 25920) = 408 07:30:17 pread64(10, "", 8192, 26328) = 0 07:30:17 stat64("/home/ew/.maildir/.INBOX.vomiteer/dovecot.index.log", {st_mode=S_IFREG|0600, st_size=26328, ...}) = 0 07:30:17 fstat64(10, {st_mode=S_IFREG|0600, st_size=26328, ...}) = 0 07:30:17 time(NULL) = 1390289417 07:30:17 setsockopt(11, SOL_TCP, TCP_CORK, [1], 4) = 0 07:30:17 write(11, "* 32 EXISTS\r\n", 13) = 13 07:30:17 setsockopt(11, SOL_TCP, TCP_CORK, [0], 4) = 0 07:30:17 epoll_wait(9, <unfinished ...> (Nothing happened after this) #

22 Jan '14

Hello, I got stucked on Kerberos auth with Dovecot: Jan 22 17:48:36 test dovecot: auth: Error: LDAP: binding failed (dn cn=AUTH\_ldap): Local error, SASL(-1): generic failure: GSSAPI Error: Unspecified GSS failure. Minor code may provide more information (Credentials cache file '/tmp/krb5cc_1003' not found) kinit and and ldapsearch with gssapi auth are working. Are there instructions how to set up Kerberos auth with Dovecot and Active Directory? How does Dovecot handle Kerberos tickets? best regards Christian

[Dovecot] master password
by Marc Perkel 21 Jan '14

21 Jan '14

This is probably easy but how would a set a secret static master password so that if I typed it in for any login it would be happy? I can't use the * separator method in this case because it screws up squirrelmail.

[Dovecot] Failure in doveconf
by Andrew Ray 21 Jan '14

21 Jan '14

I ran into a problem while configuring dovecot. Quickly reading the paragraph below, I saw "yes" as one of the options, and put that into the config, as below: # In case of password mismatches, log the attempted password. Valid values are # no, plain and sha1. sha1 can be useful for detecting brute force password # attempts vs. user simply trying the same password over and over again. # You can also truncate the value to n chars by appending ":n" (e.g. sha1:6). auth_verbose_passwords = yes The result from doveconf -n was: doveconf: Error: x�η doveconf: Fatal: Error in configuration file /etc/dovecot/dovecot.conf: 0pη (where the error message was always a changing, apparently random set of characters.) So I managed, by going back through the config file and commenting out options, to find this was the problem and then finally read what are the acceptable values. Any other place that I have tried to give a non acceptable value I get a reasonable error message with line number and problem. Well, now I fixed my original problem, but something needs to be adjusted in the error handling code.

[Dovecot] forwarded message is broken in 2.2.10 with pigeonhole-0.4.2
by Burckhard Schmidt 21 Jan '14

21 Jan '14

Hi, forwarding a message with sieve like redirect:copy "me(a)other.domain"; was working without any problem until dovecot-2.1.17, dovecots lmtp and dovecot-2.1-pigeonhole-0.3.5. Using dovecot-2.2.10 , dovecots lmtp and dovecot-2.2-pigeonhole-0.4.2 the structure of a forwarded message is broken. Content of a message is not displayed or an attachment (for instance pdf) can not be opened by (different) clients. Writing a html mail or plain one makes no different. I have compared two messages and the main different is a missing Content-Type: multipart/alternative; boundary="...." to encapsulate the body of the forwarded message. Was it lost in sieve?

[Dovecot] Dovecot doesn't seem to report all subfolders to Thunderbird
by dovecot＠voidptr.de 21 Jan '14

21 Jan '14

Hi, I've recently migrated my emails from a Yahoo account to my own mailserver on a VPS. Ever since then, Thunderbird seems to have issues with the mailbox's directory structure: When I start Thunderbird, it immediately deletes the local copies of all 3rd-level folders (i.e. subfolders of a subfolder of a folder in the mailbox root). Since that didn't happen with the Yahoo account, I assume it's some kind of error or misconfiguration of Dovecot. Here's an example of the mailbox structure: voidptr.de '-> University '-> IEEE '-> Conference "University" and "IEEE" work without problems, but "Conference" gets deleted locally every time I start Thunderbird. When I collapse and re-expand "University" in the folder panel, all subfolders (including "Conference") reappear, but Thunderbird has to re-download the contents of "Conference", since it deleted the local copies earlier. It looks as if Dovecot only reported the topmost two folder levels when Thunderbird requests a folder list... Is there any way I can change that behavior?
