Hi! I am create replication between two Debian 8.2 servers with dovecot 2.2.13. It work, but wont now more about replication used and i didn't now where i can red it: 1. aggregator - documentation and what he done? 2. replicator - full description or man for him 3. dsync - full description or man for him 4. doveadm replicator status - full description for all his points: * Queued 'sync' requests - when it started and what it is mean? * Queued 'high' requests - when it started and what it is mean? * Queued 'low' requests - when it started and what it is mean? * Queued 'failed' requests - when it started and what it is mean? * Queued 'full resync' requests - when it started and what it is mean? (wherry often i see this point is active on status for all my mail accounts) * Waiting 'failed' requests - i now what is it! * Total number of known users - i now what is it! 5. can dovecot create replication in real-time????

Doveadm client/server possible?
by Leon Kyneur 19 Oct '15

19 Oct '15

Hi As my mail infrastructure grows I'm now looking at the possibility of running all my doveadm commands from a central location. Wondering if there is a way to configure an inet_listener on doveadm and have a client elsewhere connect to it? Have seen the inet_listener for replication but not sure if it can also be used for general client server communication. Thanks Leon

Order in which UIDs are assigned..
by Akash 17 Oct '15

17 Oct '15

Hi, I just want some clarification on how Dovecot's IMAP assigns UIDs when it picks files from the "new" directory of a Maildir. What I am observing is that only ctime has a role to play in it. For example if there are two files in "new", a.msg & z.msg. Even when a.msg has lower mtime than z.msg and "a" comes before "z" alphabetically, dovecot will assign z.msg a lower UID if its ctime is lower than a.msg. Is this correct? Secondly, when mails are placed into Maildir through a external mechanism by-passing LDA, by any means is it possible for IMAP to run seive on it when it migrates the files from new to cur and indexes them? I understand that this might not be a valid question as mail is delivered already so there is nothing to filter :-) -Akash

doveadm-search-query pattern format
by Frank-Ulrich Sommer 17 Oct '15

17 Oct '15

Hello, the doveadm-search-query documentation specifies a 'pattern' for many search keys. Unfortunately it does not mention the format specification of this pattern (special characters, wildcards, ...). I'm using dovecot 2.2.9 but also searched the current documention on dovecot.org. Where can I find further documentation concerning the exact specification of the pattern format?

hi everyone need a few questions answering if possible before i can complete some modifications on my mailserver 1 how do i modify my user_query line in dovecot-sql.conf for quotas 2 is my iterate_query line ok 3 should i use lmtp or lda to deliver the quota warnings in quota-warning.sh my server is using lmtp but i've only seen examples using lda 4 how do i break long lines in dovecot.conf, is it the same as postgresql where you leave a space on the next line before continuing the txt. i would like to break the cipher line in dovecot.conf over multiple lines 5 have i configured my namespace section correctly so that i can substitute for the autocreate plugin also could you give the files a quick look over to make sure there isn't any unnecessary additions that shouldn't be there or omissions that should be there thanks shadrock ============ /etc/dovecot/dovecot.conf disable_plaintext_auth = no mail_privileged_group = vmail log_timestamp = "%Y-%m-%d %H:%M:%S " log_path = /var/log/dovecot.log auth_debug_passwords=yes mail_debug=yes verbose_ssl=yes ssl_prefer_server_ciphers = yes ssl_dh_parameters_length = 2048 ssl_cert = </etc/ssl/certs/postfix.crt ssl_key = </etc/ssl/private/postfix.key ssl_ca = </etc/ssl/ca.crt ssl_protocols = !SSLv2 !SSLv3 ssl_cipher_list = ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES256-GCM-SHA384:DHE-RSA-AES128-GCM-SHA256:DHE-DSS-AES128-GCM-SHA256:kEDH+AESGCM:ECDHE-RSA-AES128-SHA256:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA:ECDHE-ECDSA-AES128-SHA:ECDHE-RSA-AES256-SHA384:ECDHE-ECDSA-AES256-SHA384:ECDHE-RSA-AES256-SHA:ECDHE-ECDSA-AES256-SHA:DHE-RSA-AES128-SHA256:DHE-RSA-AES128-SHA:DHE-DSS-AES128-SHA256:DHE-RSA-AES256-SHA256:DHE-DSS-AES256-SHA:DHE-RSA-AES256-SHA:AES128-GCM-SHA256:AES256-GCM-SHA384:AES128-SHA256:AES256-SHA256:AES128-SHA:AES256-SHA:AES:CAMELLIA:DES-CBC3-SHA:!aNULL:!eNULL:!EXPORT:!DES:!RC4:!MD5:!PSK:!aECDH: auth_mechanisms = plain login passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } userdb { driver = prefetch } userdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } #namespace inbox { # separator = / # type = private # inbox = yes # location = maildir:/home/mailboxes/Maildir # list = yes # prefix = INBOX. #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 #} #} mail_plugins = quota # protocols = "pop3 imap lmtp" protocols = pop3 imap lmtp sieve plugin { autocreate = Trash autocreate2 = Sent autosubscribe = Trash autosubscribe2 = Sent sieve = ~/.dovecot.sieve sieve_global_path = /etc/dovecot/sieve/default.sieve sieve_dir = ~/sieve sieve_global_dir = /etc/dovecot/sieve/global/ quota = dict:User quota::proxy::quotadict quota_rule2 = Trash:storage=+10%% quota_warning = storage=100%% quota-warning +100 %u quota_warning2 = storage=95%% quota-warning +95 %u quota_warning3 = storage=80%% quota-warning +80 %u quota_warning4 = -storage=100%% quota-warning -100 %u # user is no longer over quota } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } } service managesieve-login { inet_listener sieve { port = 4190 } } service managesieve { } service dict { unix_listener dict { group = vmail mode = 0660 user = vmail } user = root } service quota-warning { executable = script /usr/local/bin/quota-warning.sh user = vmail unix_listener quota-warning { group = vmail mode = 0660 user = vmail } } protocol imap { mail_plugins = $mail_plugins autocreate imap_quota } protocol sieve { managesieve_max_line_length = 65536 managesieve_implementation_string = dovecot log_path = /var/log/dovecot-sieve-errors.log info_log_path = /var/log/dovecot-sieve.log } protocol lmtp { postmaster_address=postmaster(a)thisdomain.co.uk hostname=testy.thisdomain.co.uk mail_plugins = $mail_plugins sieve quota info_log_path = /var/log/dovecot-lmtp.log } dict { quotadict = pgsql:/etc/dovecot/dovecot-dict-sql.conf } protocol pop3 { mail_plugins = quota pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_uidl_format = %08Xu%08Xv } --(postgresql stuff)-- CREATE DATABASE mail WITH OWNER mailreader;

Strange indexing behavior on HTML emails ..
by Akash 16 Oct '15

16 Oct '15

Hi, In continuation to the issue I had posted about long back: http://www.dovecot.org/list/dovecot/2014-August/097362.html I did further testing today on a fresh new Debian & latest Dovecot and observed a undesired behavior. I am using fts_lucene & following sequence of commands on a empty test account me(a)myself.com: doveadm expunge -u 'my(a)myself.com' mailbox 'INBOX' all cat test.eml | /usr/lib/dovecot/dovecot-lda -e -f you(a)yourself.com -d me(a)myself.com doveadm search -u 'akash(a)mailjol.in' mailbox 'INBOX' text ABCD Search command does or doesn't find the email with slight variation in the content of test.eml. Here are the results: test.eml content: ----------------------------- From: you(a)yourself.com To: me(a)myself.com Subject: Test Message Content-Type: text/html <div id="mydiv">ABCD 1234</div> ----------------------------- RESULT: OK. The email is found. test.eml content (double quotes inside div tag replaced with single): ----------------------------- From: you(a)yourself.com To: me(a)myself.com Subject: Test Message Content-Type: text/html <div id='mydiv'>ABCD 1234</div> ----------------------------- RESULT: None. The email isn't found. test.eml content (single quotes in div but content/type header removed): ----------------------------- From: you(a)yourself.com To: me(a)myself.com Subject: Test Message <div id='mydiv'>ABCD 1234</div> ----------------------------- RESULT: OK. The email is found. What could be the reason for this? -Akash
