[Dovecot] Quota
by Christian Rößner 05 Nov '12

05 Nov '12

Hi, is it possible to ask Dovecot for a users quota by talking to the Dovecot server over TCP? I know about doveadm quota -u <user>, but I would like to know, if I can query for that over a network connection (on the Postfix ML they suggested writing a policy service that checks quota. Postfix is not always on the same server as Dovecot is). Does the LMTP protocol give that information somehow? I am not so familiar with LMTP. Or some Unix-Socket to query that could also be configured as inet_listener?

[Dovecot] maildir S= and W=
by Christoph Anton Mitterer 05 Nov '12

05 Nov '12

Hi. Even new mails delivered by my MDA don't get the ,S= and ,W= fields set... (but when I "upload" a mail via IMAP to dovecot, they are set) Is there some place in dovecot where I need to enable this? Or would it be the MDA that has to calculate and set this already when placing a file in ./new? Thanks, Chris.

I don't know if Dovecot takes advantage of this in any way though. Joseph Tam <jtam.home(a)gmail.com>

Dear listmembers. I have the following login_log_format_elements = service=%s user=<%u> session=%{session} method=%m rip=%r lip=%l mpid=%e %c %k Maybe I have overseen the config option to add the %{session} also to the logout line. Here a example from my log: ### Nov 3 00:46:43 <HOST> dovecot: imap-login: Login: service=imap, user=<USER>, session=ETV8v4vNfwB/AAAB, method=CRAM-MD5, rip=127.0.0.1, lip=127.0.0.1, mpid=14874, TLS, TLSv1.1 with cipher AES256-SHA (256/256 bits) zlib compression Nov 3 00:46:43 external dovecot: imap(USER): Disconnected: Logged out in=15649 out=80199 ### Thanks for help and answers.

Hi Javier, yes i see. Storage for now is just a 3tb sata2 hdd, so i guess that write performance is around 100 MB/s What do you think about that ?

[Dovecot] dovecot dimensioning
by mancyborg＠gmail.com 01 Nov '12

Hi All, first post here, nice to meet you :) I've been using dovecot + postfix + clamav + spamassassin for years but always with few users. Now i must build a server for 1500 users, they will use various email software (thunderbird, outlook, ..) the webmail (i'm not sure if squirrelmail or roundcube) and blackberry devices (with the BIS service). There will be around 1000 domains (virtual_domains) and postfix will read its users and domains from mysql. Let's say that they will send and receive around 5000 emails per hour (10K in total per hour). I was thinking to use karspersky server instead of clamav. I already have the hardware, it is a server with 4 physical cpu (Intel Xeon E5504 @ 2.00GHz) and 24 gb of ram, do you think it is enough ? Thanks for supporting, regards and have a nice day, Mike

[Dovecot] IMAP proxy between Office 365 client/Sun Messaging Server

I would like to be able to migrate messages from existing end-user accounts on Sun Messaging Server to Office 365 using an administrator login and password. Unfortunately the migration tool for Office 365 doesn't support SASL AUTHENTICATE PLAIN login. The online documentation I've found suggests that I should be able to configure dovecot as an IMAP proxy and have it log in to Sun Messaging Server with AUTHENTICATE PLAIN and encode_base64("user\0admin\0adminpw") in response to a login from the Office 365 migration tool. I'd like to configure dovecot to run only the IMAP proxy if possible. I was thinking of setting all accounts to use the same (strong) password in the proxy. Would anyone be willing to share a sample configuration? Thanks, John Dalbec ellucian Luminis system administrator Youngstown State University

[Dovecot] Unable to get Managesieve working
by Cliff Dunn 31 Oct '12

31 Oct '12

I have Roundcube webmail (v. 0.8.2) running with the managesieve plugin (v. 5.1). I am able to create sieve rules without any problems in Roundcube, but incoming mail is not being processed with the rule I specify. I suspect there is something that isn't configured correctly in dovecot, but unfortunately I am unable to find a resolution online and my very limited knowledge of dovecot isn't allowing me to solve this problem on my own. I am including my dovecot config below. Please keep my knowledge level in mind when suggesting options and let me know if there is any other information I can provide to help troubleshoot the problem. Thanks for any assistance! # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-amd64 x86_64 Debian 6.0.6 log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps managesieve ssl_cert_file: /etc/ssl/certs/postfix.pem ssl_key_file: /etc/ssl/private/postfix.key ssl_cipher_list: ALL:!LOW:!SSLv2 login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(managesieve): /usr/lib/dovecot/managesieve-login mail_privileged_group: mail mail_location: maildir:~/mail:LAYOUT=fs:INBOX=~/mail/ mbox_write_locks: fcntl dotlock mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(managesieve): /usr/lib/dovecot/managesieve mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(managesieve): /usr/lib/dovecot/modules/managesieve auth default: mechanisms: plain login passdb: driver: pam passdb: driver: pam userdb: driver: passwd userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix plugin: sieve: ~/.dovecot.sieve sieve_dir: ~/mail/sieve

[Dovecot] Dovecot stops to work - anvil problem

Hi all, we have a problem about anvil, it seems that when we have a high load the dovecot stops to work. Sometimes it is sufficient to make a dovecot reload, but sometimes we have to restart it.

[Dovecot] lmtp out of memory - raw backtrace
by Daniel Parthey 31 Oct '12

31 Oct '12

Hi, Our setup: - 4 hosts with director and mailbox instance - delivery via director lmtp into mailbox lmtp - mailbox format: mdbox - storage on NFS - OS: Linux 2.6.32-44-server x86_64 Ubuntu 10.04.4 LTS - Dovecot 2.1.10 - Pigeonhole 0.3.3 We're getting strange "out of memory" lmtp errors/backtrace with dovecot 2.1.10 accompanied by high load caused caused by a lot of lmtp deliveries to one user. First action would be to increase vsz_limit to a higher value, but I just want to make sure there is no bug - before blindly increasing this limit. I think it should not crash and corrupt mdbox, even if memory limit is reached: Oct 29 20:14:56 10.129.3.249 dovecot: lmtp(26698, user1(a)example.org) Fatal: pool_system_realloc(16777216): Out of

[Dovecot] POP3 Proxy : user format not accepted
by Christian Gregoire 30 Oct '12

30 Oct '12

Hello, I want to use Dovecot as a POP3 proxy (http://wiki.dovecot.org/HowTo/ImapProxy) All is working fine on my sample platform, except that I have plenty (several thousands) of users that login using local_part#domain, instead of local_part@domain, which is an old setting on my POP3 server. And in that case, Dovecot returns 'Authentication failed'. Here is my proxy table : mysql> select * from tbl_proxy; +--------------------+-------------+--------------------+ | user | host | destuser | +--------------------+-------------+--------------------+ | christian(a)mydom.fr | 10.10.100.1 | christian(a)mydom.fr | | christian#mydom.fr | 10.10.100.1 | christian(a)mydom.fr | +--------------------+-------------+--------------------+ If I login on the Dovecot proxy with the '@' version, everything is fine : root : ~> telnet 10.10.100.24 110 Trying 10.10.100.24... Connected to 10.10.100.24 (10.10.100.24). Escape character is '^]'. +OK Dovecot ready. user christian(a)mydom.fr +OK pass azerty42 +OK christian#mydom.fr has 3 messages (3561 octets) And MySQL logs show the query : 121030 12:55:28 3 Query SELECT NULL AS password, host, destuser, 'Y' AS nologin, 'Y' AS nodelay, 'Y' AS proxy, 'Y' AS nopassword FROM tbl_proxy WHERE user = 'christian(a)mydom.fr' If I login on the Dovecot proxy with the '#' version, it fails : root : ~> telnet 10.10.100.24 110 Trying 10.10.100.24...

If I login directly on the POP server with the same credentials, no problem : root : ~> telnet 10.10.100.1 110 Trying 10.10.100.1... Connected to 10.10.100.1 (10.10.100.1).

Authenticate yourself. user christian#mydom.fr +OK Password required for christian#mydom.fr pass azerty42 +OK christian#mydom.fr has 3 messages (3561 octets) Any idea ? Is the '#' not internally supported in the user login by Dovecot ? Thanks in advance. Christian

[Dovecot] Dovecot does not update acl_shared_dict file
by Chris Smith 30 Oct '12

30 Oct '12

Hi all, Firstly, thanks for all your effort with this software. Much appreciated. I am having a slight issues trying to enable reading of other users mailboxes. The docs are a little sparse for those that aren't mailadmin heros, I wonder if anyone could please help me see where I am going wrong. I would like to allow some users to list and read the mailboxes of others. E.g: When User1 logs in, they are presented with a list of their own folders, and those of User2, User3, etc to which they have (e.g. read/list) access I followed the instructions on the wiki (for Version 1.X)- there are two concepts here: 1. Grant some [e.g. list/read] access on a mailbox folder to a particular user 2. Enable the acl_shared_dict to allow dovecot to track (and display to IMAP clients) the folders to which they have access. This will take the form of a BDB file: /var/lib/dovecot/shared-mailboxes.db This file can only be updated by using the SETACL command. *This is where I have the problem*. The SETACL command does nothing. No matter how hard I try, I cannot get dovecot to update this file. The only indication I have that the file exists and is readable by dovecot is the disappearance from the logs of the line: No acl_shared_dict setting - shared mailbox listing is disabled So I can see that dovecot knows the file is there because it does not complain any more. The file is there (because I created it myself, although it is empty: size = 0), and in a moment of weakness I made sure it could be updated (this will be changed back!): ls -l /var/lib/dovecot/shared-mailboxes.db -rwxrwxrwx 1 dovecot dovecot 0 2012-10-30 12:27 /var/lib/dovecot/shared-mailboxes.db But if I try to update the ACL, absolutely nothing happens: [ > command ] [ < reply ] > telnet localhost 143 < * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE STARTTLS AUTH=CRAM-MD5] Email server > a login [User2] [pass] < a OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT IDLE CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH ACL RIGHTS=texk] Logged in > a SETACL Inbox [User 1] rl < a OK Setacl complete.

[Dovecot] Problem about SSL for Dovecot.
by sheng-wei.lim 30 Oct '12

30 Oct '12

Hi All, With the below setting (cropped), the ssl certificate(signed by godaddy) don’t seems to work. It will still ask me if I want to accept this certificate. I have use the same certificate for apache host and postfix it works without any prompt. dovecot version : 2.0.19 # OS: Linux 3.2.0-32-generic-pae i686 Ubuntu 12.04.1 LTS Dovecot config: ssl = required ssl_cert = </aaa/4/merged5.crt ssl_key = </certs/proximityjobs.key userdb { args = /etc/dovecot/dovecot-mysql.conf driver = sql } verbose_ssl = yes protocol lda { auth_socket_path = /var/run/dovecot/auth-master lda_mailbox_autocreate = yes log_path = /var/log/sieve.log mail_plugins = quota sieve autocreate acl postmaster_address = root } protocol imap { imap_client_workarounds = tb-extra-mailbox-sep mail_plugins = quota imap_quota autocreate acl imap_acl } protocol pop3 { mail_plugins = quota pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_uidl_format = %08Xu%08Xv } Best Regards, Sheng Wei

[Dovecot] Save/restore IMAP session state
by Timo Sirainen 30 Oct '12

30 Oct '12

Some future Dovecot version will have "imap-idle" processes where IDLEing IMAP connections get moved, so the system wouldn't waste so much memory for all the IDLEing imap processes. A week ago I thought I'd see how easy it would be to implement this. I got a basic proof of concept working as a "X-STATE" command. Save the state: a x-state * STATE AQDLW45QdwAAAAMAAABuAQAAAAAAAFAcffYAPHnpFctbjlDbYQAAcEmzCwAA a OK State exported. Restore the state: b x-state AQDLW45QdwAAAAMAAABuAQAAAAAAAFAcffYAPHnpFctbjlDbYQAAcEmzCwAA b OK State imported. This could also be used to implement quick session state restoring for webmails (as suggested by Michael Slusarz). For getting the imap-idle process there would have to be code that: * triggers the session saving when process is IDLEing * figures out what filesystem paths the imap-idle should be looking at (i.e. paths to selected mailbox's dovecot.index.log file and maybe for e.g. maildir new/) * send the session state string, paths and imap connection fd to imap-idle process via UNIX socket * implement the actual imap-idle process * implement a way for imap-idle process to send back the state and connection fd to restore the imap process The patch is ugly and still missing many things. Anyway I thought I'd include it here just in case someone was really eager to continue implementing it. :) I'm not sure when I'll have time for it. A full patch would probably have to have some session_save()/session_restore() functions in lib-storage API. But a quick and dirty way is possible to implement for v2.1 as well, as long as some IMAP extensions aren't used (most importantly rfc5267).

I did consider it, and you're right, it is tricky to get it absolutely right. If robusteness and security was of utmost importance, I would abandon PHP too. I was scaling the solution to the OP's technical ability and apparent size of their operation -- if poppwd passes muster, this wouldn't be too far off. Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] does dovecot interpret any mail headers specially with maildir?
by Christoph Anton Mitterer 30 Oct '12

30 Oct '12

Hi. For mbox, http://wiki2.dovecot.org/MailboxFormat/mbox#Dovecot.27s_Metadata lists a numer of mail headers: - X-IMAPbase - X-IMAP - X-UID - Status - X-Status - X-Keywords - Content-Length that are treated specially by dovecot. It also suggests, that these should be stripped by the LDA (I guess in order that someone sending you such mail cannot set the status or keywords, or even "attack you" by setting a bogus Content-Length). I wondered, when using maildir, are there any headers that dovecote would treat specially, too? And which I therefore should strip? Thanks, Chris.

[Dovecot] No failover from director to backend?
by Patrick Westenberg 29 Oct '12

29 Oct '12

Hi everyone, short version: Is there no built in failover mechanism for the director service to handle a backend failure? Long version: I have a frontend server running the director service and two backends. Due to maintenance I had to shut down one of the backends which caused connection errors for the users being directed to this backend. I was very surprised as I expected the director to redirect these users to the remaining backend. Am I wrong or is the director not working as expected?

[Dovecot] INBOX permissios woes
by Josep L. Guallar-Esteve 29 Oct '12

29 Oct '12

Hello, I have a dovecot system that uses winbind authentication against Active Directory. I set it up by following the directions in the wiki. That works great. When a new user receives an email, the inbox is created with permissions 600 (rw- --- --) and ownership user:mail , even though I did chmod 02770 /var/spool/mail. And then, when dovecot tries to access the inbox, it throws the error: Oct 29 13:47:59 imap-login: Info: Login: user=<user1>, method=PLAIN, rip=10.0.0.6, lip=10.0.0.26, mpid=29047, secured Oct 29 13:47:59 imap(user1): Error: stat(/var/mail/user1) failed: Permission denied Oct 29 13:47:59 imap(user1): Error: stat(/var/mail/user1) failed: Permission denied Accessing users' Sent, Trash, creating new folders.... all that works fine. I've been looking at the documentation, reading the wiki, searching on google, asking on IRC. If you have any hint or documentation that I've must have overlooked, please let me know.
