Can't access maildir with dovecot
by Julien Cubizolles 27 Oct '15

27 Oct '15

I'm a total newbie regarding imap servers. I'm trying to set up a Offlineimap/dovecot/Gnus system and Gnus complains that it cannot access the maildir... Here is my setup, put together by copying stuff from around the web without any prior knowledge of these tools... * Offlineimap is setup to use the $HOME/Maildir-free/, using --8<---------------cut here---------------start------------->8--- preauthtunnel = /usr/lib/dovecot/imap -o mail_location=maildir:$HOME/Maildir-free --8<---------------cut here---------------end--------------->8--- in the local maildir part of ~/.offlineimaprc. * The Maildir-free maildir has been correctly (I think) populated with a single "General" folder. /home/wilk/Maildir-free: total used in directory 52 available 5502852 drwxrwxr-x 6 wilk wilk 4096 oct. 23 11:10 . drwx------ 240 wilk wilk 20480 oct. 23 15:06 .. drwxrwxr-x 2 wilk wilk 4096 oct. 23 11:09 cur -rw-rw-r-- 1 wilk wilk 348 oct. 23 11:10 dovecot.index.log -rw-rw-r-- 1 wilk wilk 51 oct. 23 11:10 dovecot-uidlist -rw-rw-r-- 1 wilk wilk 8 oct. 23 11:09 dovecot-uidvalidity -r--r--r-- 1 wilk wilk 0 oct. 23 11:09 dovecot-uidvalidity.5629f967 drwx------ 6 wilk wilk 4096 oct. 23 11:16 General -rw-rw-r-- 1 wilk wilk 0 oct. 23 11:09 maildirfolder drwxrwxr-x 2 wilk wilk 4096 oct. 23 11:09 new drwxrwxr-x 2 wilk wilk 4096 oct. 23 11:09 tmp * dovecot is not setup to start as a server (no script in /etc/rc*.d/) and I didn't configure anything in any /etc/dovecot/ file (maybe I should have ?) * Gnus is supposed to access the maildir as an IMAP server through dovecot: I have: (nnimap "FreeOffline" (nnimap-stream shell) (nnimap-shell-program "/usr/lib/dovecot/imap -o mail_location=maildir:$HOME/Maildir-free") in gnus-secondary-select-methods * I try to access this maildir as follows /usr/lib/dovecot/imap -o mail_location=maildir:/home/wilk/Maildir-free/ * PREAUTH [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS THREAD=ORDEREDSUBJECT MULTIAPPEND URL-PARTIAL CATENATE UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS SPECIAL-USE BINARY MOVE] Logged in as wilk * LIST "" * * LIST (\HasNoChildren) "."

As you can see, the "General" folder doesn't appear, and there is a mention of "INBOX" even though there is no folder under this name (but I guess that's a default for any IMAP system). Accordingly, Gnus only displays a INBOX folder when browsing the FreeOffline IMAP server, and complains that it contains no message. What's the correct way to setup dovecot? Thanks for your help. Julien.

2.2.18 initial setup permissions problem
by Forrest 27 Oct '15

27 Oct '15

I'm using Dovecot 2.2.18, compiled from source, on CentOS 6. I'm running into a permissions problem with my first rollout of Dovecot which has to do with directory permissions: Oct 23 14:34:51 mail dovecot: imap(username): Error: stat(/home/username/Maildir/tmp) failed: Permission denied (euid=596(<unknown>) egid=97(dovecot) missing +x perm: /home/username/Maildir, dir owned by 500:500 mode=0700) This being setup with the Dovecot wiki instructions. I may have misunderstood an initial setting. If I change permissions to my personal Maildir directory struct to be dovecot:dovecot it works fine, but this seems unusual. Dovecot is running as root: root 19176 0.0 0.1 2876 1096 ? Ss 14:28 0:00 /usr/local/sbin/dovecot dovecot 19178 0.0 0.0 2780 996 ? S 14:28 0:00 dovecot/anvil root 19179 0.0 0.1 2912 1144 ? S 14:28 0:00 dovecot/log root 19225 0.0 0.1 3544 1776 ? S 14:38 0:00 dovecot/config dovecot 19226 0.0 0.1 3332 1408 ? S 14:38 0:00 dovecot/auth root 19227 0.0 0.0 2776 916 ? S 14:38 0:00 dovecot/ssl-params I can't seem to figure this one out. Can someone point me in the right direction. Thanks.

Haproxy and Dovecot auth
by Giuseppe Civitella 26 Oct '15

26 Oct '15

Hi all, I'd like to use Haproxy to balance an auth service on a couple of Dovecot directors to have a redundant sasl service for my Postfix instances. While I configure the Postfixes to use, as smtpd_sasl_path, a direct connection to one of the directors I notice no errors. When I redirect the smtpd_sasl_path through an Haproxy balanced connection, I receive an error the first time I try to sen an email. The error is: SASL PLAIN authentication failed: Connection lost to authentication server If then I send more emails I receive no errors. If I do not send emails for a few minutes, the error appears again. The relevant Haproxy configuration is the following: listen auth *:12345 mode tcp balance source log global option tcplog option log-health-checks stick-table type ip size 200k expire 30m stick on src default-server inter 1000 fall 3 rise 1 server dovecot-director01 dovecot-director01:12345 check Do anyone have an idea about what it's missing? Thanks a lot Giuseppe -- Giuseppe Civitella gcivitella(a)entermail.it

Memory leak or misconfiguration: Repeated allocation of very large block
by Sebastian Wolfgarten 25 Oct '15

25 Oct '15

Dear all, I am using Dovecot 2.2.19 and I keep on getting the following warnings in my mail.log file on FreeBSD 10: Oct 24 10:45:28 server1 dovecot: imap: Error: GC Warning: Repeated allocation of very large block (appr. size 20480): Oct 24 10:45:28 server1 dovecot: imap: Error: May lead to memory leak and poor performance. I am wondering whether this is a configuration issue (i.e. a mistake in my current config) or whether I am hitting a bug. What’s the best way of figuring this one out? I tried increasing the verbosity of the logs but it did not really provide me with further information. Any ideas?

Notify plugin doesn't send mailbox_create notifications
by Lukas Mika 25 Oct '15

25 Oct '15

Hi there, I'm running dovecot 2.2.13 on my debian jessie server. When installing my own dovecot plugin, I noticed that there are no notifications coming from the notify plugin. I checked back with the mail_log plugin, but also this plugin doesn't log any notifications when a new mailbox is created; the mail is saved to the new inbox never the less. I ran dovecot 2.2.9 before on my Ubuntu Trusty (14.04) server, where with the same settings the plugins worked. Can you reproduce this issue and does anybody know a fix to this? Here are the relevant bits of my config: 20-lmtp.conf: protocol lmtp { mail_plugins). mail_plugins = $mail_plugins sieve mail_log notify } 10-logging.conf ... plugin { mail_log_events = mailbox_create mail_log_fields = uid box } ... Cheers

Question about dovecot replication
by Urban Loesch 25 Oct '15

25 Oct '15

Hi, last week I installed 2 servers with two dovecot nodes and replication in active/active mode located in different datacenters. Based on the howto from wiki "http://wiki2.dovecot.org/Replication" it works great. According to the wiki it is recomended to run "doveadm purge" on both systems continously, because "doveadm purge" will not be replicated by the replication service. No problem so far. But I have one doubt: is it also reccmended (for keeping maildata in sync) to run "doveadm replicator replicate '*'" continously on both nodes? Or is it enough on only one node? Or should I run "doveadm sync -A tcp:anotherhost.example.com" in regular intervalls? Perhaps once a day on both nodes? Thanks Urban Loesch

help filtering messages
by James 23 Oct '15

23 Oct '15

Hello, I'm attempting to use sieve-filter on a local mailbox. I've defined mail_location as follows: % grep mail_location /etc/dovecot/conf.d/10-mail.conf mail_location = maildir:~/Mail I have a large number of mailboxes / mail in ~/Mail: ~ % find Mail | wc -l 63158 There are definitely a few messages in INBOX: ~ % find Mail/INBOX/cur | wc -l 5 I must admit, I'm completely new to sieve and have just begun experimenting with it. Based on a super helpful blog post[1], I quick set up the following ~/.sieve: % cat ~/.sieve require ["fileinto"]; # rule:[TEST] if header :contains "Subject" "Test Email" { fileinto "TEST"; stop; } As mentioned, there are numerous emails in INBOX. This email is located in ~/Mail/INBOX/cur/<blah> and, for verbosity (and to ensure I'm not making a foolish mistake), I've displayed it here: From: Test Account <test(a)test.com> To: "Me" <me(a)test.com> Subject: Test Email Date: Mon, 19 Oct 2015 14:55:06 +0000 This is a test email. Looking at the sieve filter recipe and email message, it appears that I should have a match, no? sieve-filter appears to disagree: % sieve-filter -C ~/.sieve INBOX sieve-filter(test_user): Debug: Effective uid=1000, gid=1000, home=/home/test_user sieve-filter(test_user): Debug: Namespace inbox: type=private, prefix=, sep=, inbox=yes, hidden=no, list=yes, subscriptions=yes location=maildir:~/Mail sieve-filter(test_user): Debug: maildir++: root=/home/test_user/Mail, index=, indexpvt=, control=, inbox=/home/test_user/Mail, alt= Thinking this was because sieve will only filter on new messages, I moved the file from cur to new. No change. Any thoughts on why this may be happening? Thanks! 1 https://mebsd.com/configure-freebsd-servers/dovecot-pigeonhole-sieve-filter…

Hibernation disabled when mailbox selected
by Joseph Tam 20 Oct '15

20 Oct '15

After setting imap_hibernate_timeout to 60s, I could not find any hibernated connections after a few hours. I tested hibernation and made an observation: IDLE'd imap sessions only hibernate if they don't have a mailbox SELECT'd, otherwise they never hibernate. Is this the way it's supposed to work?

TLS communication director -> backend with X.509 cert checks?
by Heiko Schlittermann 19 Oct '15

19 Oct '15

Hello, using Dovecot 2.2.9 and a setup with directors and backends. The communication between directors and backends needs to be TLS secured. The director config contains a list of hostnames for the backends. (implicit list because of multiple A/AAAA records for a single hostname or explicit list of several host names) On connection setup from a client the director connects to the selected backend. But it seems (not checked in the source yet), that for SSL certificate verification the director doesn't know the original host name anymore. The certificate's CN gets compared to the IP address the director connects to. Oct 12 23:56:51 director2 dovecot: director: Error: director(2001:683:921:f33::5:1:9090/out): connect() failed: Connection reset by peer Oct 12 23:57:53 director2 dovecot: imap-login: Error: proxy: hostname doesn't match SSL certificate at 2001:683:921:f33::5:fe:993: user=<foo>, method=PLAIN, rip=2001:638:912:f33::1:1, lip=2001:638:912:f33::5:2, TLS, session=<fLrUa+8hggAgAQY4CRIPMwAAAAAAAQAB> In 10-directors.conf I've: director_mail_servers = backend1.<domain> backend2.<domain> Should I create certificates with IP address in SAN? (Any hint about the correct syntax for the openssl.conf is welcome). Or is there any chance that this is fixed already or will be fixed in the near future or even better, that it's my fault?

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

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>

Emails with sender MISSING_MAILBOX@missing_domain
by grupo correo 15 Oct '15

15 Oct '15

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

Hi all, Thanks for making Dovecot. I just transitioned from Debian Wheezy to Void Linux. It was fairly easy to get Dovecot working on my Void box, and having Dovecot makes all of my email activities easier by doing one thing and doing it right. Thank you for such great software. SteveT

Dualstack IPv4/IPv6 setup with directors
by Heiko Schlittermann 13 Oct '15

13 Oct '15

Hi, still using 2.2.9, I've two directors, and these directors use both IPv4/IPv6 addresses. `host directors.<domain>` returns one A and AAA for each of the two directors: directors.<domain> has address 149.x.y.96 (director1) directors.<domain> has address 149.x.y.97 (director2) directors.<domain> has IPv6 address 2001:x:y:f33::5:1 (director1) directors.<domain> has IPv6 address 2001:x:y:f33::5:2 (director2) But connecting the the neighbor director gives: Oct 13 21:23:29 director1 dovecot: director: Warning: Director 2001:x:y:f33::5:2:9090/left disconnected us with reason: Invalid input: ME 149.x.y.96 9090 Oct 13 21:23:29 director1 dovecot: director: Error: director(149.x.y.97:9090/out): connect() failed: Connection refused Oct 13 21:23:29 director1 dovecot: director: Warning: net_connect_ip(): ip->family != my_ip->family Oct 13 21:23:29 director1 dovecot: director: Error: Remote director thinks it's someone else (connected to 2001:x:y:f33::5:1:9090, remote says it's 149.x.y.96:9090) I assume it's because the director uses only one (IPv4 OR IPv6) address for it's own identity, right?

Storage Design (Regligious War, Whatever)
by Kelsey Cummings 13 Oct '15

13 Oct '15

We've been running dovecot director setup using MAILDIR++ spools on NFS served by 4 (aging) Netapp clustered filers and are considering modernizing our storage. There's nothing particularly wrong with the existing storage except the age, density and power consumption don't compare well when against new systems. Refreshing the Netapps is an option but they come at a substantial cost. The last time we were looking one of the recommended hot DIY setups was Linux NFS backed by XFS on N mirrors but this predated the availability of stable ZFS in FreeBSD or Linux as well as products like FreeNAS. A FreeBSD NFS/ZFS filer on commodity hardware with zil/l2arc on a PCIe SSD seems like an attractive, affordable and easily scaled out solution which also would allow us to leverage compression at the filesystem layer. Does anyone have any experience running ZFS spool storage? If so, how do you handle DR/HA for spool storage? Thoughts on how this might compare to using DRBD? Any pitfalls to watch out for or general pointers? Suggestions on pool configuration? -K
