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

Dovecot top stats
by Kilburn Abrahams 15 Oct '15

15 Oct '15

Hi, I have being try to track down top email users to sometime. When I do a network traffic check I can see there is about 15 times more email traffic pulled from mail server than sent. The problem I am trying to track down is which users are the culprit. I have enabled doevcot stats and I can do a doveadm stats dump user but I get a 0 for disk_input, disk_output, read_bytes and write_bytes. I do get mail_read_bytes numbers but I am not sure these numbers are correct. I there a top utility that works well so I can see email traffic from users mailboxes. The doveadm top does not work well. I also tried the perl scripts and that does not do a much better job. Thanks Kilburn

What do you mean by "iterate"? If you mean whether you can look up a password entry in a multi-entry file, then yes, definitely. If you mean to sequentially go through it and do a first/last/best match, probably not. Joseph Tam <jtam.home(a)gmail.com>

Hello, we are working in the migration from courier-imap to dovecot 2.2.10-4.el7_0.1.x86_64. Some emails that send a internal application show as sender "MISSING_MAILBOX@missing_domain", i use like email client Horde using dovecot like server. But if i open that email with Horde and courier-imap i can see the correct email sender. I think that the email of the sender is no correct or not accomplish some RFC. Can anyone help me to understand this? Thank you
