[Dovecot] dovecot-2.2.beta1: do not removes e-mail with enabled replication
by Евгений Басов 16 Jan '13

16 Jan '13

Hello. I'm created two installations of dovecot-2.2.beta1 with identical config. Without replication each server works good. With replication enabled every changes are replicated between these ones. When I probe remove or move some email in another folder it is disappears and reappears again and again in source folder and appears in destination folder. Thus increasing number of letters like with copy. Possible reasons cause of the problem: - bug - configuration settings of dovecot - users with wich dovecot works and users rights. Which version is true? If this not a bug, what should be corrected in the configuration? Configuration: auth_debug = yes auth_mechanisms = plain login auth_verbose = yes import_environment = TZ lock_method = flock mail_debug = yes mail_location = mdbox:/var/vmail/%d/%n:INDEX=/var/vmail_indexes/%d/%n/ mail_plugins = " quota notify replication" mail_temp_dir = /var/spool/lmtp-dovecot mdbox_preallocate_space = yes mdbox_rotate_interval = 1 days mdbox_rotate_size = 50 M namespace inbox { inbox = yes location = mailbox Шаблоны { auto = create } mailbox Archive { auto = create special_use = \Archive } mailbox Archives { auto = create special_use = \Archive } 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 = } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { mail_replica = remote:vmail@mailsys.office.megagroup.ru quota = dict:Domain quota:%d:redis:host=127.0.0.1:prefix=domain/ quota2 = dict:User quota::redis:host=127.0.0.1:prefix=user/ quota2_rule = *:storage=0 quota2_rule2 = Trash:storage=+5%% quota_rule = *:storage=0 quota_rule2 = Trash:storage=+5%% } service aggregator { fifo_listener replication-notify-fifo { mode = 0600 user = vmail } unix_listener replication-notify { mode = 0600 user = vmail } } service auth-worker { user = $default_internal_user } service auth { unix_listener auth-userdb { group = $default_internal_user mode = 0666 user = $default_internal_user } } service config { unix_listener config { mode = 0600 user = vmail } } service dict { unix_listener dict { mode = 0600 user = $default_internal_user } } service doveadm { user = vmail } service imap-login { process_min_avail = 5 service_count = 1 } service imap-postlogin { executable = script-login /usr/local/bin/imaptrackLastLogin.sh user = $default_internal_user } service imap { executable = imap imap-postlogin process_limit = 1024 } service lmtp { inet_listener lmtp { address = *, :: port = 24 } process_min_avail = 5 } service pop3-login { process_min_avail = 5 service_count = 1 } service pop3-postlogin { executable = script-login /usr/local/bin/pop3trackLastLogin.sh user = $default_internal_user } service pop3 { executable = pop3 pop3-postlogin process_limit = 1024 } service replicator { process_limit = 1024 process_min_avail = 3 } ssl_cert = </etc/ssl/dovecot/server.pem ssl_key = </etc/ssl/dovecot/server.key userdb { driver = prefetch } userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } verbose_proctitle = yes protocol imap { mail_plugins = " quota notify replication imap_quota" } Filesystem permissions: # ls -l /var/ drwxr-xr-x 3 vmail vmail 24 Jan 16 16:14 vmail drwxr-xr-x 3 vmail vmail 24 Jan 16 16:14 vmail_indexes # ls -l /var/spool/ drwxrwx--- 2 dovecot dovecot 6 Jan 16 15:11 lmtp-dovecot Users: dovecot:x:97:97:added by portage for dovecot:/dev/null:/sbin/nologin uid=97(dovecot) gid=97(dovecot) groups=97(dovecot) dovenull:x:102:102:added by portage for dovecot:/dev/null:/sbin/nologin uid=102(dovenull) gid=102(dovenull) groups=102(dovenull) vmail:x:999:999:User for work with local mail storage:/home/vmail:/bin/bash uid=999(vmail) gid=999(vmail) groups=999(vmail),97(dovecot) Selects from user database are rights because isolated installations are works and not get errors.

[Dovecot] FTS what to use ?
by Erik Colson 16 Jan '13

16 Jan '13

Hi I'm currently using dovecot 2.0 with squat fts which does a nice job. However I'm thinking about upgrading to dovecot 2.1 and the wiki isn't clear about which fts can or should be used with it. Is squat support dead ? As the wiki mentions that the config syntax is obsolete, I'm not sure if squat is obsolete also ? If not, what is the new syntax ? But in the case squat is dead.. what is the recommended alternative nowadays ? I don't really need substring search, but it is a nice thing to have. PS : I will be using dovecot 2.1 with maildir thanks -- erik

[Dovecot] Dovecot subtree problem in ldap/ad search
by Marcus Jüttner 15 Jan '13

15 Jan '13

Hallo Im trying to set up an Postfix and Dovecot mailserver with ActiveDirectory interation. Postfix is doing well and even Dovecot does ... but I have one big problem! My AD Accounts ar stored in two Subfolders ou=Bischoff Benutzer LTT, dc=bischoff-ltt, dc=local ou=Bischoff Benutzer Nbg, dc=bischoff-ltt, dc=local If i use "base = ou=Bischoff Benutzer LTT, dc=bischoff-ltt, dc=local" everything is fine but users from "ou=Bischoff Benutzer Nbg" will not work. Thats ok so far. But when i use "base = dc=bischoff-ltt, dc=local" none user will be found even if i use "scope = subtree". Postfix has no problem with the base set to "dc=bischoff-ltt, dc=local". Ldapsearch has no problem too. I use Version 2.1.12 on Gentoo Linux with a 2003R2 AD Is scope=subtree broken in Dovecot? Must I set some special parameters for Windows AD? My Config: hosts = 192.168.1.98 dn = bischoff-ltt\ldapsearch dnpass = xxxxx auth_bind = yes ldap_version = 3 scope = subtree base = dc=bischoff-ltt, dc=local #base = ou=Bischoff Benutzer LTT, dc=bischoff-ltt, dc=local #base = ou=Bischoff Benutzer Nbg, dc=bischoff-ltt, dc=local user_attrs = =home=/var/dovecot/%Ln/,=mail=maildir:/var/dovecot/%Ln/ user_filter = (&(ObjectClass=person)(sAMAccountName=%u)) pass_filter = (&(ObjectClass=person)(sAMAccountName=%u)) Thanks for Help Marcus

[Dovecot] Define custom ldap libraries when building Dovecot
by Nikolaos Milas 15 Jan '13

15 Jan '13

Hello, I would like to compile Dovecot using custom ldap libraries, located at a particular custom system location. How should I alter the config process to specify that the include dir is "/usr/local/openldap/include" and the lib dir is "/usr/local/openldap/lib64" and not the standard ones (/usr/include/ and /usr/lib64/ respectively) on RHEL/CentOS 5 (x86_64). Note that all of the above files/folders exist on the file system at the same time. The idea is to build dovecot against current openldap v2.4.x libraries and not against the available (by the OS) ancient openldap v.2.3.x libs. Please, advise. Thanks, Nick

[Dovecot] Zlib maildir reindex bug?
by Richard Platel 14 Jan '13

14 Jan '13

Hi Running dovecot 2.1.7 (from debian repo). We have some old compressed maildir messages with the wrong S= size in the filename (our fault). If I delete index files, log in to the mailbox and try to FETCH the bad message, dovecot complains about the incorrect message size, attempts to fix the filename and disconnects the client. However, it changes the filesize to the size of the message on disk, not the message's uncompressed size. For subsequent clients, the FETCH works, but dovecot logs an error (and maybe re-indexes the mailbox?) and the message UID changes.

If the UIDs are just headers, why don't you simply checksum without them: sed -e '/^Whatever-header:/d' < $file | md5sum grep -Ev '^Whatever-header:' < $file | md5sum Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] sieve reject to wrong address?
by Felix Rubio Dalmau 14 Jan '13

14 Jan '13

Hi all, I have succeed in setting up postfix (to send/receive emails), dovecot to access the folders via IMAP, all using TLS and sieve under dovecot to manage filters. I have also set up a sieve rule to reject those mails whose size exceeds 2 MB... and I'm really proud of everything, because it is my first time!! However, when rejecting the mail, instead of sending a mail saying "I'm sorry blah, blah, blah" to the originary sender, it is sent to the final recipient (that is, me). Do you know how to solve it? Is it a problem from sieve or dovecot? I think is some misconfiguration of my dovecot installation, because the sieve rule is: ################ if size :over 2M { reject text: Ho sento, no accepto cap correu de mes de 2MB de tamany. Sisplau, puja els fitxers mes grans a un servidor i envia'm un link. Gracies. I'm sorry, I do not accept mail over 2 MB in size. Please upload larger files to a server and send me a link. Thanks. . ; } ################ dovecot log looks like: Jan 14 17:34:16 server dovecot: lda(felix@server): sieve: msgid=<201301141734.16203.felix@server>: rejected message from <felix@server> (reject) Jan 14 17:34:16 server postfix/cleanup[2011]: 2B59CB59: message- id=<dovecot-1358181256-51155-0@server> Jan 14 17:34:16 server postfix/pipe[2012]: 311AF4E0: to=<felix@server>, relay=dovecot, delay=1, delays=0.81/0.02/0/0.19, dsn=2.0.0, status=sent (delivered via dovecot service) Thank you! -- Felix Rubio Dalmau

[Dovecot] Dovecot SASL Client support?
by Charles Marcus 14 Jan '13

14 Jan '13

Hi all, I seem to recall mention of SASL client support either being added, but can't remember for sure. The wiki says nothing about Client support (now, or in the future)... http://wiki2.dovecot.org/Sasl So - is there support for it now? If not, is it planned for anytime soon? Thanks, -- Best regards, Charles
