[Dovecot] dovecot+LDAP/AD encoding issue
by Wiethoff, Helge 09 Aug '12

09 Aug '12

Hello everybody, i have a problem with dovecot+Active Directory as Authentication-Service. I am not able to use special characters (äöüß (german umlaut)) within a password. Normally I would suggest that the ldap-query is done in UTF-8 but as I debugged the auth-process, I have seen that the password is ISO-8859-1 encoded. The "original" query (from roundcube for example) is UTF-8 encoded (I dumped the POST-Query). So far I wasn't able to find my error by myself or by searching the web. Maybe someone of you can give me a hint :-) Thanks and greetings from Germany, Helge ---- dovecot --version 2.0.16 ---- D-AS01:/etc/dovecot # grep -v '^ *$#.*$\?$' dovecot-ldap.conf.ext uris = ldap://10.37.5.90 dn = CN=ldap-d-as01,CN=Users,DC=tfh-bochum,DC=de dnpass = xxxx auth_bind = yes ldap_version = 3 base = ou=Benutzer, ou=Lehre, dc=tfh-bochum, dc=de user_attrs = =uid=10000,=gid=10000,=home=/srv/mail/%Ld/%Ln user_filter = mail=%u pass_attrs = =uid=10000,=gid=10000,=home=/srv/mail/%Ld/%Ln pass_filter = (&(mail=%u)(!(extensionAttribute3=*))) ---- dovecot -n # 2.0.16: /etc/dovecot/dovecot.conf # OS: Linux 2.6.37.6-0.11-default x86_64 openSUSE 11.4 (x86_64) auth_debug = yes auth_mechanisms = plain login auth_username_translation = %Lu auth_verbose = yes mail_location = maildir:~/Maildir mail_max_userip_connections = 1000 mail_plugins = quota managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave namespace { inbox = yes list = yes location = prefix = INBOX/ separator = / subscriptions = yes type = private } namespace { list = yes location = maildir:%%h/Maildir:INDEX=%h/Maildir/shared/%%u:CONTROL=%h/Maildir/shared/%%u prefix = shared/%%u/ separator = / subscriptions = yes type = shared } passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { acl = vfile acl_shared_dict = file:/srv/mail/shared-mailboxes quota = maildir:Quota quota_rule = *:storage=1G sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_max_redirects = 10 } protocols = imap pop3 sieve lmtp service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { group = vmail mode = 0770 user = root } } service imap-login { process_min_avail = 4 service_count = 0 } service managesieve-login { inet_listener sieve { address = * port = 4190 } inet_listener sieve_deprecated { address = * port = 2000 } process_min_avail = 2 service_count = 0 } ssl_ca = </etc/ssl/certs/tfh_dfn_dtag_cacert.pem ssl_cert = </etc/ssl/certs/imap.stud.tfh-bochum.de-20110530-cert-302177588.pem ssl_key = </etc/ssl/private/imap.stud.tfh-bochum.de-20110530.key userdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } protocol lmtp { mail_plugins = quota } protocol imap { mail_plugins = quota acl imap_acl imap_quota } protocol pop3 { mail_plugins = quota } ________________________________ Helge Wiethoff Medienzentrum Telefon: +49 (234) 968 8717 Fax: +49 (234) 968 3453 E-Mail: Wiethoff(a)tfh-bochum.de Technische Fachhochschule Georg Agricola für Rohstoff, Energie und Umwelt zu Bochum Staatlich anerkannte Fachhochschule der DMT-Gesellschaft für Lehre und Bildung mbH Herner Straße 45 44787 Bochum http://www.tfh-bochum.de ________________________________ Träger: DMT-Gesellschaft für Lehre und Bildung mbH Sitz der Gesellschaft: Bochum Registergericht: Amtsgericht Bochum Handelsregister: B 4052 Geschäftsführung: Prof. Dr. Jürgen Kretschmann (Vorsitzender) Manfred Freitag

[Dovecot] Mail deletion and Solr index update
by Matthias Rieber 09 Aug '12

Hi, I've deleted 10000s emails and it seems that every mail is removed with a single request from Solrs index. This works, but it's quite slow. Is it possible/plans to improve that? Matthias

[Dovecot] Quota dict configuration
by Uros 08 Aug '12

08 Aug '12

Hi, I have enabled quota dict with mysql following wiki http://wiki2.dovecot.org/Quota/Dict Everything work as expected. I just have a question about query used for updating quota usage. I already check the source file dict-sql.c but i still can't figure it out. I store user info in a mysql table where only left (user) part of an email address is stored with foreign id for domain conected to domain table. The problem is administration because quota table have primary key whole email. Is there even possible to configure quota dict settings to use separate variables %n and %d like in user and password query? -- lp Uroš

[Dovecot] dsync and pop3 migration plugin fails for large inbox due to idle timeout
by Nikolai Schupbach 08 Aug '12

08 Aug '12

Timo, There is a problem with the dsync POP3 migration plugin when syncing a large INBOX. What happens is dsync establishes a connection to the POP3 server at the beginning of the sync, but then it sits there idle until it's used to sync the UIDLs. On a very large inbox with many thousands of messages it will be idle for longer than a POP3 server's idle timeout setting. When the UIDL sync occurs dsync produces the following errors (because the connection has been lost due to the POP3 server's inactivity timeout): dsync(first.last(a)test.co.nz): Error: pop3c(pop3.test.com): Server disconnected unexpectedly dsync(first.last(a)test.co.nz): Error: pop3_migration: Failed to get header for msg 13: Disconnected dsync(first.last(a)test.co.nz): Error: pop3_migration: Failed to get header for msg 14: Disconnected dsync(first.last(a)test.co.nz): Error: pop3_migration: Failed to get header for msg 15: Disconnected dsync(first.last(a)test.co.nz): Error: pop3_migration: Failed to get header for msg 16: Disconnected ... dsync(first.last(a)test.co.nz): Error: pop3_migration: Failed to get header for msg 14492: Disconnected dsync(first.last(a)test.co.nz): Error: pop3_migration: Failed to get header for msg 14493: Disconnected dsync(first.last(a)test.co.nz): Error: pop3_migration: Failed to get header for msg 14494: Disconnected Also at the end of the dsync it actually has an exit status of 0, but it shouldn't because the POP3 sync failed, and none of the UIDLs are retained. Dsync should try to keep the POP3 connection alive, by sending a regular 'NOOP' command to the POP3 server, or it should simply reconnect if sees the connection is lost. At the moment the only work around is to increase the POP3 server's idle timeout to a multi hour value, which isn't a good work around as it causes a lot of inactive POP sessions to bank up. Regards, Nikolai.

The problem is solved!!!! In the library "src/lib-sieve/plugins/vacation/cmd-vacation.c", in the package "dovecot-sieve" or "dovecot-pigeonhole" modify: smtp_handle = sieve_smtp_open(senv, reply_to, NULL, &f); smtp_handle = sieve_smtp_open(senv, reply_to, reply_from, &f); You can check the correct operation in your logs. /var/log/maillog postfix/smtpd[27112]: connect from smtp.mydomain.com postfix/smtpd[27112]: A95D2168456: client=smtp.mydomain.com postfix/cleanup[27114]: A95D2168456: message-id=<A5BBC98AAF65424CADBFB6ACF0003E8B03FB4B74(a)example.com> postfix/smtpd[27112]: disconnect from smtp.mydomain.com postfix/qmgr[17010]: A95D2168456: from=<asier.cidon(a)example.com>, size=7274, nrcpt=1 (queue active) postfix/pipe[27115]: A95D2168456: to=<asier.cidon(a)mydomain.com>, relay=dovecot, delay=0.09, delays=0.01/0/0/0.08, dsn=2.0.0, status=sent (delivered via dovecot service) postfix/qmgr[17010]: A95D2168456: removed /var/log/dovecot.log dovecot: auth(default): master out: USER 1 asier.cidon(a)mydomain.com uid=xxx gid=xxx quota_rule=*:bytes=524288000 home=/buzon/asier.cidon dovecot: deliver(asier.cidon(a)mydomain.com): sieve: msgid=<A5BBC98AAF65424CADBFB6ACF0003E8B03FB4B74(a)example.com>: sent vacation response to <asier.cidon(a)example.com> dovecot: deliver(asier.cidon(a)mydomain.com): sieve: msgid=<A5BBC98AAF65424CADBFB6ACF0003E8B03FB4B74(a)example.com>: stored mail into mailbox 'INBOX' /var/log/maillog postfix/pickup[17009]: B221D168458: uid=xxx from=<asier.cidon(a)mydomain.com> postfix/cleanup[27114]: B221D168458: message-id=<dovecot-sieve-1344420404-703760-0(a)mda.mydomain.com> postfix/qmgr[17010]: B221D168458: from=<asier.cidon(a)mydomain.com>, size=661, nrcpt=1 (queue active) postfix/smtp[27195]: B221D168458: to=<asier.cidon(a)example.com>, relay=smtpinterno.mydomain.com, delay=0.04, delays=0.01/0/0.01/0.01, dsn=2.0.0, status=sent (250 2.0.0 Ok: queued as A3A092280B3) postfix/qmgr[17010]: B221D168458: removed

[Dovecot] doveadm import is always verbose
by Jürgen Obermann 08 Aug '12

08 Aug '12

Hello, with dovecot versions up to 2.1.9, when I use: doveadm import -u guser mbox:/tmp/mbox/guser/restore_2012-05-08 restore_2012-05-08 all it always sends out info messages for every mail copied like that: doveadm(guser): Info: copy from mymail: box=restore_2012-05-08/mymail, uid=5, msgid=<######>, size=6999462 I had expected to see these info messages only if I add the verbose option to doveadm. And using the option -v with: doveadm -v import -u guser mbox:/tmp/mbox/guser/restore_2012-05-08 restore_2012-05-08 all makes no difference at all, the same messages appear. The verbose option seems to be always on. Is this a bug or intended behaviour?

[Dovecot] Dovecot with Company - level Quota
by Kavish Karkera 08 Aug '12

08 Aug '12

Hi Timo, We are using maildir as quota-backend , and performing user level quota, which is working fine. (using dovecot 2.x ). Now the requirement is to , restrict the quota to client / company level along with user level quota. For. eg. We have a mailbox path like /mail/mailstore/10001/kavish.karkera(a)linoquery.com/Maildir/ where 10001 is Client code (unique number given to very client) instead of domain name. So there would be two quota's one at company level and other user level. Such as 10001(linoquery.com) = 5GB ---> Company Quota kavish.karkera(a)linoquery.com = 0 ? ---> User Quota If the sum of the user quota under 10001/* exceeds the 5GB limit then the mails for that particular domain should get bounced. Please Help , if this is possible. Regards, Kavish Karkera

[Dovecot] replication chain
by Костырев Александр Алексеевич 08 Aug '12

08 Aug '12

good day! I wonder if it is possible to make a chain of replication in dovecot 2.1.9. Now I'm using two way replication(I use proxy to redirect users) and it's working just fine but is it possible to setup replication like this: serverA ---> serverB --> server C <--- I've added additional mail_replica2 on serverB and after restart dovecot didn't complain about errors, with doveconf -n I am able to see two replica's settings but user's mails aren't replicating to server C. no errors in logs. I want to use server C as backup server with lvm snapshots.

Do the same user(s) have this problem and/or do each user have their own mail configuration for their mail readers? If yes, I would also check that the port and security protocol matches (i.e. clear/TLS/SSL on ports 110/110/995 respectively). Mismatched configurations could cause what you describe. Log messages could also be helpful here. Joseph Tam <jtam.home(a)gmail.com>

Re: [Dovecot] redirect actions exceeds policy limit

Thank you David, I saw that in the share/docs but we didn't have the /conf.d/ folder or any of the extra conf files in place. I created that directory, copied the file over, made my changes and all is well again. Not sure why things were setup the way they were, after looking at the other files in conf.d it would appear the previous sysadmin had merged a lot of those bits and pieces into the main dovecot.conf file. Perhaps leftovers from v1.x days. Will likely address that down the road when we update that server. Mike Greene Rock Island Technology Solutions, Inc.

[Dovecot] Pigeonhole sieve include namespace regression
by Daniel Piddock 07 Aug '12

07 Aug '12

Hi, We've recently upgraded from Dovecot 1.2.15 with Sieve 0.1.18 (Debian Squeeze) to Dovecot 2.1.8 and Pigeonhole 0.3.1. We provide a selection of global sieve scripts to make users' lives easier and one noticed that some of these have stopped working. I tracked it down to them having personal scripts with the same name. Using a really simple sieve script: require "include"; include :personal "svn"; include :global "svn"; sievec debug output for sieve 0.1.18 (trimmed a bit): * Required extensions: 0: include (16) 1: fileinto (5) * Included personal script 'svn' (block: 3): [script code here] * Included global script 'svn' (block: 4): [script code here] * Main program (block: 1): 00000000: EXTENSIONS [1]: 00000001: include 00000002: INCLUDE: 00000004: script: svn.sieve [ID: 1, BLOCK: 3] 00000006: INCLUDE: 00000008: script: svn.sieve [ID: 2, BLOCK: 4] 0000000a: [End of code] sievec debug output for Pigeonhole 0.3.1: * Required extensions (block: 1): 0: include (id: 16; block: 4) 1: fileinto (id: 5) * Included personal script 'svn' (block: 5): [script code here] * Main program (block: 2): Address Line Code 00000000: DEBUG BLOCK: 3 00000001: EXTENSIONS [1]: 00000002: include 00000003: 2: INCLUDE: 00000005: script: `svn' from /home/notroot/sieve/svn.sieve [ID: 1, BLOCK: 5] 00000007: 3: INCLUDE: 00000009: script: `svn' from /home/notroot/sieve/svn.sieve [ID: 1, BLOCK: 5] 0000000b: 3: [End of code] As can be seen the personal script is included twice.

[Dovecot] connectionlimit for pop3s?
by Hajo Locke 07 Aug '12

07 Aug '12

Hello, i have a user who is able to do pop3 on port 110 without problems and without limits. There are ~10 real users using same public IP. When switching to port 995 to use pop3s he is limited at connection count. Some people can reach pop3s-server successful, some getting a timeout. I cant find any errors or limits within my config or in my log, there are no differences between using plain text and using tls. Are there some special loglines to grep for at this situation? Maybe i missed some lines... At the moment i dont see server-side problems. Somebody knows some typical clientside problems when this problem occurs? dovecot version is 1.2.11 Thanks, Hajo

[Dovecot] redirect actions exceeds policy limit
by Mike Greene 06 Aug '12

06 Aug '12

Hello, We have a vacation/mail forwarder plugin in squirrel mail that allows customers to forward email. It has come to my attention that there is a limit (appears to be 5) on the number of addresses that can be specified. I'm now trying to track down where this policy limit is set. This is the error we see in the customers .dovecot.sieve.log file: main_script: line 26: error: number of redirect actions exceeds policy limit. sieve: info: started log at Jul 25 07:02:54. I checked the following for possible settings: /usr/local/etc/dovecot/dovecot.conf /usr/local/etc/sieve/dovecot.sieve /usr/local/etc/sieve/global.sieve I didn't see anything specific to limiting the number of redirects.

[Dovecot] Just trying to make dovecot work.

Hi, I have to say that Dovecot is certainly the most challenging piece of software I've ever had the pleasure of setting up (due mainly to the reams of largely unhelpful documentation). After 36 almost non-stop hours reading and trying, I finally end up here. :-) I really would appreciate your help - and many thanks in advance! *************************************************************** /var/log/dovecot.info.log (showing unsuccessful login) *************************************************************** Aug 04 21:32:36 auth: Debug: Loading modules from directory: /usr/lib64/dovecot/auth Aug 04 21:32:36 auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libauthdb_ldap.so Aug 04 21:32:36 auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_sqlite.so Aug 04 21:32:36 auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libmech_gssapi.so Aug 04 21:32:36 auth: Debug: passwd-file /usr/local/etc/dovecot.passdb: Read 1 users Aug 04 21:32:36 auth: Debug: auth client connected (pid=24769) Aug 04 21:32:41 auth: Debug: client in: AUTH 1 PLAIN service=imap securedlip=::1 rip=::1 lport=143 rport=52551 resp=AHBldGVyAGZ1YXNpbjU0MTRz Aug 04 21:32:41 auth: Debug: passwd-file(peter,::1): lookup: user=peter file=/usr/local/etc/dovecot.passdb Aug 04 21:32:41 auth: Debug: client out: OK 1 user=peter Aug 04 21:32:41 auth: Debug: master in: REQUEST 1417805825 24769 1 44a3aec60ec6eaec6eff0efb99971eee Aug 04 21:32:41 auth: Debug: master out: USER 1417805825 peter Aug 04 21:32:41 imap-login: Info: Login: user=<peter>, method=PLAIN, rip=::1, lip=::1, mpid=24772, secured *************************************************************** END *************************************************************** *************************************************************** /var/log/dovecot.log (showing unsuccessful login) *************************************************************** Aug 04 21:32:41 IMAP(peter): Error: user peter: Couldn't drop privileges: User is missing UID (see mail_uid setting) Aug 04 21:32:41 IMAP(peter): Error: Internal error occurred.

[Dovecot] getting rid of old spam from +spam Maildir ?
by Voytek Eymont 06 Aug '12

06 Aug '12

I'm trying to setup per user '+spam' delivery from amavis tags, so that each user gets any mails tagged as spam to 'spam' Maildir via +spam Dovecot lmtp delivery. after say 7 days I want to delete all spams older than 7 days, if I simply delete mail files from the file system, is that a 'bad thing' ? what is a proper way to do that, and scripts ? for removing/archiving old uncollected emails in main INBOX I use archivemail from sf, but, don't think I can do subfoldrs with archivemail any pointers (and scripts) welcomed, thanks -- Voytek

Hello all, Can someone please give me a hint about how can I disable such messages to be inserted into log file(maillog this case as syslog_facility = mail)? >> dovecot: auth-worker(13377): mysql(localhost): Connected to database postfix All the '_debug' and '_verbose' statements bear the 'no' value.
