[Dovecot] Maildir filename extensions S=<size> and W=<vsize>
by Ralf Hildebrandt 25 Oct '10

25 Oct '10

I'd like to add S=<size> and W=<vsize> to the filenames in my Maildir storage for newly delivered mails. But I cannot find where I can make Dovecot's LDA add those. Anybody? http://wiki2.dovecot.org/MailboxFormat/Maildir says: A maildir filename with those fields would look something like: 1035478339.27041_118.foo.org,S=1000,W=1030:2,S which is exactly what I want, but it doesn't tell me how! -- Ralf Hildebrandt Geschäftsbereich IT | Abteilung Netzwerk Charité - Universitätsmedizin Berlin Campus Benjamin Franklin Hindenburgdamm 30 | D-12203 Berlin Tel. +49 30 450 570 155 | Fax: +49 30 450 570 962 ralf.hildebrandt(a)charite.de | http://www.charite.de

[Dovecot] fallocate and glibc 2.10
by Paul Howarth 25 Oct '10

25 Oct '10

In glibc 2.10 (32 bit) fallocate() exists but fallocate64() doesn't. When _FILE_OFFSET_BITS==64, fallocate() is a redirect to fallocate64() and the program can't be linked (fails to find symbol fallocate64). See http://bugzilla.redhat.com/500487 Attached patch detects fallocate() more robustly to guard against this problem. Cheers, Paul.

[Dovecot] "Maintenance instance"
by Ralf Hildebrandt 24 Oct '10

24 Oct '10

Does any of you have a "Maintenance instance" of dovecot? Something that will accept any user/pass combination (and thus doesn't make MUAs fail in utter unforeseen ways), and gives any user logging in a canned mail (e.g. "We're doing maintenance, go away") -- Ralf Hildebrandt Geschäftsbereich IT | Abteilung Netzwerk Charité - Universitätsmedizin Berlin Campus Benjamin Franklin Hindenburgdamm 30 | D-12203 Berlin Tel. +49 30 450 570 155 | Fax: +49 30 450 570 962 ralf.hildebrandt(a)charite.de | http://www.charite.de

24 Oct '10

Hi all, I have running dovecot-1.2.15 and I try whith dovecot-antispam-1.3 and 1.2-* if it's running for me. I use mailtrain backend to call a script when I move a mail to a specific folder. Then, I set allow_append_to_spam: yes At .config for Make dovecot-antispam. I set the plugin's name to: PLUGINNAME=isspam An then, I have another copy of the sources and .config with plugin's name set to: PLUGINNAME=nospam With this. If I put on dovecot.conf protocol imap { ... mail_plugins = isspam nospam ... } When I try to login, the connection is aborted and dovecot connection die with coredump Are there are any people with similar settings ?

[Dovecot] [stava@telcotec.se: [stava: antispam problem]]
by Lars Stavholm 24 Oct '10

24 Oct '10

Hi All, I've built the dovecot-antispam-plugin from hg.dovecot.org and installed it. I've turned on debugging with "mail_debug = yes" in dovecot.conf and restarted dovecot. However, the antispam plugin module gets loaded by dovecot, but then nothing, i.e. when moving mail from Inbox to Spam and vice versa, I see nothing. How do I get debug messages from the dovecot-antispam-plugin? There's a few i_debug() statements in there (and I added a few myself), but I don't see any of these messages. # dovecot -n # 2.0.6: /etc/dovecot/dovecot.conf # OS: Linux 2.6.34.7-0.4-desktop x86_64 openSUSE 11.3 (x86_64) auth_debug = yes auth_debug_passwords = yes auth_mechanisms = plain login auth_username_format = %Lu auth_verbose = yes base_dir = /var/run/dovecot disable_plaintext_auth = no dotlock_use_excl = yes listen = * mail_access_groups = mail mail_debug = yes mail_full_filesystem_access = yes mail_location = maildir:~/Mail:LAYOUT=fs mail_plugins = autocreate quota zlib managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date passdb { args = /etc/dovecot/ldap.conf driver = ldap } plugin { antispam_backend = dspam antispam_dspam_binary = /usr/sbin/dspam antispam_signature = X-DSPAM-Signature antispam_spam = Spam antispam_trash = Trash autocreate = Spam autocreate2 = Sent autocreate3 = Trash autosubscribe = Spam autosubscribe2 = Sent autosubscribe3 = Trash quota = fs:disk quota quota2 = fs:user quota } protocols = imap ssl = no userdb { args = /etc/dovecot/ldap.conf driver = ldap } verbose_ssl = yes protocol imap { mail_plugins = autocreate quota zlib imap_quota imap_zlib antispam } Any help appreciated /Lars Stavholm

[Dovecot] minimize mbox mdbox fragmentation
by Stan Hoeppner 22 Oct '10

22 Oct '10

Hi Timo, Any chance the mbox/mdbox writer code could be modified to do physical preallocation on files to help avoid file(system) fragmentation? Constantly appending a file is the prime recipe for causing fragmentation, and mbox is notorious for this--not a fault of Dovecot but the nature of the mbox beast. Obviously maildir doesn't have such a problem, but some (many?) of us still prefer mbox for many reasons, fast full body search being one, portability being another. mdbox file fragmentation could benefit from such a change as well. I was having a discussion on the XFS list about this, trying to tweak XFS mount options to mitigate the fragmentation effects. Alas, there is no way to do this purely at the filesystem level. From Dave Chinner, one of the lead XFS devs: "What you want is _physical_ preallocation, not speculative preallocation. i.e. look up XFS_IOC_RESVSP or FIEMAP so your application does _permanent_ preallocate past EOF. Alternatively, the filesystem will avoid the truncation on close() if the file has the APPEND attribute set and the application is writing via O_APPEND... The filesystem cannot do everything for you. Sometimes the application has to help...." How great would the effort need to be to implement something like this? Would the return on investment be sufficient to justify doing this, in your eyes? -- Stan

[Dovecot] Question about Client Certificates
by William Gallafent 21 Oct '10

21 Oct '10

Hi, I have a simple dovecot installation, version 1.2.12 of ubuntu 10.10. I also have a straightforward newbie question! I've hunted in the wiki and on the wider web, but not yet found a solution. Current status: I have successfully configured imap with tls, accessed on port 993, and for security require a valid client certificate to be presented, using ssl_require_client_cert and ssl_verify_client_cert. This is all working fine! Now I want to add a SquirrelMail service to the same server. This will connect using IMAP over port 143, without TLS. My question is: how do I achieve this! At the moment, I simply get the following in the logs: Aborted login (cert required, client didn't start TLS): method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured If I comment out the "ssl_require_client_cert = yes" in the auth default section, SquirrelMail then works fine … but I can also connect remotely without presenting a valid certificate, which is no good! At the moment I have a single auth section in dovecot.conf, the "auth default { ... }" section. I wondered if I need a second section, which does not have the ssl requirement inside it. Is that right? If so, how do I link one auth section to the imaps service, and the other to the imap service (listening only on localhost)? In other words, I want "ssl_require_client_cert = yes" for remote connections (on port 993), but "ssl_require_client_cert = no" for local connections using non-tls imap on port 143. Is this possible? Hope that late-night explanation makes sense, and hope somebody can point me in the right direction, thanks in advance! -- Bill Gallafent.

Hi, we found a serious bug while testing our migration scripts. in Solaris (or other system 5) the user variable is not always set. Dsync is not very happy about that and crashes with an segmentation fault. After hours of debugging and TWOE simple lines # USER=$LOGNAME # export USER the problem was solved! The null pointer was found - so i will go home now an drink a bottle of "Erdinger"... hope this hint helps for development - and we hope that we don't find more of these bugs :) bye Tobi -- Dr. Nagler & Company GmbH Hauptstraße 9 92253 Schnaittenbach Tel : 09622-7197-38 Fax : 09622-7197-50 Web : http://www.nagler-company.com E-Mail : tobias.daucher(a)nagler-company.com Hauptsitz: Schnaittenbach Handelregister: Amberg HRB 4653 Gerichtsstand: Amberg Steuernummer: 201/118/51825 USt.-ID-Nummer: DE 273143997 Geschäftsführer: Dr. Martin Nagler, Dr. Dr. Karl-Kuno Kunze

[Dovecot] allow_nets and local sockets
by Oliver Eales 21 Oct '10

21 Oct '10

Hello, i am running dovevot 2.0.5 using ldap authentication with the allow_nets paramter to limit access to some local networks. The problem is, when i want to use the local lmtp socket from postfix *virtual_transport = lmtp:unix:private/dovecot-lmtp * i get the follwing error: *Oct 21 15:48:03 auth: Info: passdb(username): allow_nets check failed: Remote IP not known *When using the TCP socket with postfix *virtual_transport = lmtp:localhost:30025 *it is working. (i have 127.0.0.0/8 in the allow_nets list) Is there a way, other than using two different config sets to get this working together ? Something like disabling the address lookup on local passdb sockets ? Regards, Oliver

[Dovecot] Director and CRAM-MD5

Hello, i have a setup with two director servers pointing to two backends. I don't care that much for load balancing, my main goal is high availability.

[Dovecot] Campo de quota en LDAP
by Antonio Perez-Aranda 20 Oct '10

20 Oct '10

En un principio, en los ldif que tenemos de los usuarios de prueba, tenemos el campo mailQuota. Sin embargo, si nos vamos a los schemas de qmail medianamente, con algo más de 3 años, se cambió mailQuota por mailQuotaSize y mailQuoatCount. Esto se debe entre otras cosas a que en la cabecera del fichero maildirsize del buzón, tenemos esta información, es decir, máximo tamaño ocupado y máximo número de mensajes. En el ldap de producción se sigue usando mailQuota? En el courier que tenemos montados aquí, misma versión y misma configuración que la existente en desbuz03, cuando no existe la quota del maildir directamente no da información sobre quota. ¿Estamos usando la quota de ldap? O al entregar un correo mediante Exim, se actualiza el fichero maildirsize con los valores de mailQuota. En este caso, podemos seguir con este comportamiento, o podemos utilizar la información que viene de ldap si no hay nada en el maildirsize.

[Dovecot] Outlook problem when deleting mails
by Ulf Jaenicke-Rößler 20 Oct '10

20 Oct '10

Hi, I'm seeking advice to solve the following "mystery": I set up an IMAP server on Ubuntu 10.04 (dovecot 1.2.9). It appears to work fine apart from one problem. A colleague is running Outlook 2007 on Vista and sometimes (sometimes very often, sometimes only occasionally) when he wants to delete mails, Outlook hangs for some time (he says about 1, 2 or 3 minutes) until it finally puts out a message box: "The server did not respond to this IMAP command before the connection was terminated" I have activated the outlook-idle workaround, but I learned that this doesn't do anything anymore, right? There's no error message in dovecot's logs. Nevertheless, today I found this around the time the error happened: 2010-10-12 17:13:02 imap-login: Info: Login: user=<user>, method=PLAIN, rip=192.168.100.53, lip=192.168.100.20 2010-10-12 17:13:03 imap-login: Info: Login: user=<user>, method=PLAIN, rip=192.168.100.53, lip=192.168.100.20 2010-10-12 17:15:07 IMAP(user): Info: Disconnected in IDLE bytes=272298/631645 2010-10-12 17:15:07 IMAP(user): Info: Disconnected: Logged out bytes=63/539 2010-10-12 17:15:07 IMAP(user): Info: Disconnected: Logged out bytes=462/47082 What exactly does "Disconnected in IDLE" mean? Could the error be related to the same time stamp? (I'm not yet sure, if it always happens this way if the error occurs) I also found "Disconnected in IDLE" for other users at other times, but no one other complained so far. Maybe, that's because most of the other users use Thunderbird ;-) Is this problem known? What could I do? Best regards Ulf

[Dovecot] (Single instance) attachment storage with single-dbox
by Timo Sirainen 19 Oct '10

19 Oct '10

Just a note to myself and whoever else cares, should be added to wiki once it has its own page about this: With single-dbox messages can be copied with hard linking. This means that there can be multiple files that point to the same attachment file. The attachment is now deleted only once the mail file's link count drops to zero, so this works fine.. ..until someone goes and starts manually copying files or maybe restoring from backups or whatever, causing the hard links to be replaced with separate files having link count=1, even when there are other files pointing to the same attachment file. Now deleting this one mail will delete the attachment too early. I can't think of any other reasonable way to handle this though, so unless someon has some great ideas, I think the solution is to simply add enough warnings that message store shouldn't be accessed directly. Maybe add some import/export commands to doveadm which can be used to add a bunch of mails to storage without doing it directly on filesystem.

[Dovecot] gssapi problems (postfix sasl through dovecot, dovecot imap working fine)
by Trever L. Adams 19 Oct '10

19 Oct '10

Thanks to Timo, I have solved all but one of my problems. For back ground, I am using Samba4 as an AD. I have the userdb working from LDAP just fine and kerberos authenetication for dovecot's IMAP server working fine. The problem is using dovecot's SASL with postfix. I also have plain/login working in imap and smtp. Both use pam_krb5 through pam to authenticate clients that don't have kerberos, and for now smtp. When trying to do smtp kerberos, I get the following: postfix/smtpd[6197]: warning: CLIENT_FQDN[CLIENT_IP]: request longer than 2048: AUTH GSSAPI ... dovecot: auth: Debug: client in: AUTH#0111#011GSSAPI#011service=smtp#011nologin#011lip=SERVER_IP#011rip=CLIENT_IP#011secured#011resp=<hidden> dovecot: auth: Debug: gssapi(?,CLIENT_IP): Obtaining credentials for smtp@MAILSERVER_FQDN dovecot: auth: gssapi(?,CLIENT_IP): While processing incoming data: Unspecified GSS failure.

Any help would be greatly appreciated. I have made sure that the file has proper permissions. I have regenerated the smtp cert making suer the password is accurate. I have done everything I know to try. The only thing that I am guess remains is something is broken with Thunderbird's kerberos setup for smtp. Thank you very much, Trever

We have got the very similar specs on IMAP LOGIN log, but I can't get the Logout format. Courier write like that: ... imapd: LOGOUT, user=luism.martinez, ip=[::ffff:127.0.0.1], headers=0, body=0, rcvd=131, sent=632, time=0 ¿Is there any Variables on imap_logout_format to get headers, body and time vars?

Hello Dovecot v2.0.5 zlib_save_level = 6 # 1..9 zlib_save = gz # or bz2 Is there a config option to disable zlib, even if above config are in place? If so please provide an example. If no, would it be possible to add one? Like if zlib_save_level = 0 disable zlib. So one can configure per mailbox compression level via sql database. KuiZ Thanks

[Dovecot] cmusieve and logging
by cool.chris65＠web.de 18 Oct '10

18 Oct '10

Hello, is there a way to write a logfile during sieve-actions? At least, I have trouble in reading sieve-scripts with tools from kmail ("connection refused) or thunderbird (timed out: server does not answer). There is no problem with the mailbox itself in reading or writing in it. The config for Sieve: dovecot.conf: ## ## LDA specific settings ## protocol lda { # Address to use when sending rejection mails. postmaster_address = christoph@localhost # Hostname to use in various parts of sent mails, eg. in Message-Id. # Default is the system's real hostname. #hostname = # Support for dynamically loadable plugins. mail_plugins is a space separated # list of plugins to load. # Binary to use for sending mails. #sendmail_path = /usr/lib/sendmail # UNIX socket path to master authentication server to find users. #auth_socket_path = /var/run/dovecot/auth-master debug = yes log_path = /var/log/dovecot/dovecot-deliver-errors.log info_log_path = /var/log/dovecot/dovecot-deliver.log # Enabling Sieve plugin for server-side mail filtering mail_plugins = cmusieve } plugin { # Here you can give some extra environment variables to mail processes. # This is mostly meant for passing parameters to plugins. %variable # expansion is done for all values. #sieve = /var/sieve-scripts/%u/sieve sieve=~/.dovecot.sieve # Quota plugin.

SQL) # maildir: Maildir++ quota # fs: Read-only support for filesystem quota #quota = maildir # ACL plugin. vfile backend reads ACLs from "dovecot-acl" file from maildir # directory. You can also optionally give a global ACL directory path where # ACLs are applied to all users' mailboxes. The global ACL directory contains # one file for each mailbox, eg. INBOX or sub.mailbox. #acl = vfile:/etc/dovecot-acls # Convert plugin. If set, specifies the source storage path which is # converted to destination storage (mail_location) when the user logs in. # The existing mail directory is renamed to <dir>-converted. #convert_mail = mbox:%h/mail # Skip mailboxes which we can't open successfully instead of aborting. #convert_skip_broken_mailboxes = no # Trash plugin. When saving a message would make user go over quota, this # plugin automatically deletes the oldest mails from configured mailboxes # until the message can be saved within quota limits.

Currently works only with maildirs. When a user # expunges mails, the mails are moved to a mailbox in another namespace # (1st). When a mailbox is deleted, the mailbox is moved to another namespace # (2nd) as well. Also if the deleted mailbox had any expunged messages, # they're moved to a 3rd namespace.

Hi, I've upgraded my Dovecot from 1.2 to 2.0.5. Everything is working fine on my Gentoo, also login with imaps and pop3s. But: I have in my config autocreate folders for new users.

I have been carefully watching the ver 2.x tree rev from week to week and I await the defacto signal from people that it is in fact at least as solid at 1.2.12, that signal being adoption by people in busy mail servers. So therefore I await ver 2.0.6 with a mix of conflicting anticipation and trepidation. :-) -- Dennis Clarke dclarke(a)opensolaris.ca <- Email related to the open source Solaris dclarke(a)blastwave.org <- Email related to open source for Solaris

There is still a rather large number of Solaris 8 Sparc servers out there running in production and based on the conversations I have had with some sysadmins they will upgrade them when the smoke comes out. That could be another five years. So, before you say "stability has less to do with that" you should see the horrendous work it takes to port an app from the open source world ( usually Linux people with tons of Linux-isms/GCC-isms in it ) over to an old POSIX/XPG4 ( POSIX.1-1990, POSIX.2-1992, POSIX.1b-1993, POSIX.1c-1996 etc ) compliant UNIX.

[Dovecot] Split plugin config in diferents files
by Antonio Perez-Aranda 18 Oct '10

Hi all, Is possible to split dovecot.conf with a very very big plugin {} section? Maybe, some like apache with sites-enabled.d Then, we could have a file per plugin.

[Dovecot] Version checks and API/ABI/sonames
by Axel Thimm 18 Oct '10

18 Oct '10

Hi, pigeonhole/sieve check against dovecot's version comparing to what they have been built against. This means that whenever there is a minor version of dovecot released pigeonhole/sieve need to be rebuilt and then redistributed to users even if there is no need for it (I'm thinking of packaged versions of dovecot and dovecot-pigeonhole). Could the checks become ABI-version aware, so that rebuilds and redistribution are kept to a minimum? Maybe Timo is already keeping API/ABI stability between minor updates, so the version checks should be against the first two version components only. Thanks! -- http://thimm.gr/ - http://ATrpms.net/

[Dovecot] Retrieving unread message count
by Brandon Davidson 18 Oct '10

18 Oct '10

Timo, I'm working with a webmail client that periodically polls unread message counts for a list of folders. It currently does this by doing a LIST or LSUB and then iterating across all of the folders, running a SEARCH ALL UNSEEN, and counting the resulting UID list. Eventually I'd like to see it using RFC5819 LIST-EXTENDED, but that requires a fair bit of work. In the mean time I'm trying to speed up the existing iteration. I've got it working using 'STATUS "mailbox" (UNSEEN)', but the language in RFC3501 suggest that this may be slow. There is a counterproposal to use RFC4731 ESEARCH and do 'SELECT "MAILBOX"'; 'SEARCH RETURN (COUNT) UNSEEN'. >From an IMAP server perspective, which do you anticipate would be faster? >From a client perspective it seems like STATUS would be better since it involves less round-trips to the server and less output parsing, but given the warnings in the RFCs there is concern that it is in fact be more expensive. -Brad

Huh? What are you talking about? If dovecot has tcpwrapper support and is compiled -DTCPWRAP then it can run as a standalone daemon and will consult the hosts.allow/deny files, no need for inetd of any type. man 3 hosts_access man 5 hosts_access for details on tuning. Tcpwrapper tuning is far more powerful than people realise.

[Dovecot] strange behavior with virtual accounts and imap
by vladi 18 Oct '10

18 Oct '10

hi, I've recently setup new mailserver with dovecot and postfix. They use mysql and virtual accounts. All works perfectly except.. There is one group account named info, all the mail is forwarded to every other account. Users download their mail via Outlook (2003, 2007) with imap. If someone downloads email send to info and delete it after that. Outlook stoke the message and doesn't delete it immediately, thats normal. But if later someone else downloads his mail and it have received the same letter to info. The message appear as if it's already deleted by that user. But is supposed to be unreaded. I cant find any info why is this happening. Please help

[Dovecot] quota sql dict permissions dilemma
by LEVAI Daniel 18 Oct '10

18 Oct '10

Hi! I'm trying to set up SQL based dict quota. The quota is working, gets updated but I had to configure really loose file permission to make it work: dovecot.conf: dict { quota = pgsql:/etc/dovecot/dovecot_dict-sql.conf } service dict { unix_listener dict { mode = 0660 group = vmail # sidenote: I noticed that writing the number equivalent # of 'vmail' here does not work. Why? } } # ~ls -la /etc/dovecot/dovecot_dict-sql.conf -rw-r----- root vmail dovecot_dict-sql.conf # ~ls -la /var/dovecot/dict srw-rw---- root vmail /var/dovecot/dict= Every virtual user lookup returns a 'gid' field, and it is always 'vmail' (actually it is the number equivalent of 'vmail'). Despite that the imap process should run as the 'uid' and 'gid' values returned from the userdb, it can not read the dict config file: dovecot.log: dict: Error: Can't open configuration file /etc/dovecot/dovecot_dict-sql.conf: Permission denied dict: Error: Failed to initialize dictionary 'quota' lda(<username>): Error: read(/var/dovecot//dict) failed: Remote disconnected Now I must set o+r to the config file, which I really don't want to, given that it contains the db username and password. Strange thing is that the group r/w permission is enough for the dict= socket, and it doesn't need world-wide permissions at all.

Everytime I try to create a folder under my imap-inbox, I get an error like "can't upload folder...", but after this message I can see a new folder under my inbox-folder, but I can't use it ... With a thundermail-client I can create a subfolder without any erro and I can use it r (but only first level).

[Dovecot] Quota, Postgres + Postfixadmin
by Roman 17 Oct '10

17 Oct '10

Hi everybody, i am currently testing dovecot-1.2.9 together with postfix, postgres and postfixadmin. After setting up the basics, i wanted to get the quotas working... So i edited the dovecot.conf: mail_plugins = quota imap_quota mail_plugins = sieve quota quotadict = pgsql:/etc/dovecot/dovecot-dict-quota.conf quota = dict:user::proxy::quotadict and dovecot-dict-quota.conf: connect = host=localhost dbname=postfix user=yyy password=xxx map { pattern = priv/quota/storage table = quota2 username_field = username value_field = bytes } map { pattern = priv/quota/messages table = quota2 username_field = username value_field = messages } After moving some mail on and off the account and finally cleaning out any mail (verified via console) quota2 looks like this: username bytes messages test(a)testdomain.de -1009339 -1 So it seems to me its calculating sth. wrong? Or am i doing sth. wrong? greetings, Roman -- printk(KERN_ERR "happy meal: Transceiver and a coke please."); linux-2.6.6/drivers/net/sunhme.c

[Dovecot] Convert plugin
by Egbert Jan van den Bussche 15 Oct '10

15 Oct '10

Hi, I'm trying to get old mail from /var/mail/<user>, where <user> is the (sometimes) huge mailfile, not a directory, converted to the maildir INBOX in ~/Maildir. Users have no ~/mail directory; they were supposed to use pop3 only. I'm trying the example from the wiki: plugin { convert_mail = mbox:~/mail:INBOX=/var/mail/%n } but have still not succeded. I tried /var/mail/<user> where <user> is a file and /var/mail/<user>/<user> where user is first a diredtory en the second <user> a file. I also used the filename 'inbox', since the logging suggested that to me. Other logging seems to indicate that the right maildir++ info is composed. I'm in vor any advise!

[Dovecot] Weird glitches with public folders - Dovecot not using per-user INDEX?
by Kádár Tamás (KTamas) 15 Oct '10

15 Oct '10

Hi I have this public folder: namespace { location = maildir:/home/_shared/projects:INDEX=~/Maildir/_shared prefix = shared. separator = . subscriptions = no type = public } Access is controlled by ACLs, everyone who has access is 'lrwstipek' except for some people who also have 'xa' privileges. As you can see it is set to put its index to the user's Maildir so they can have per-user \Seen flags. And that is the case -- most of the time anyway. But for some folders, and I can't figure out why those, they just don't work: if someone sets a message read it immediately becomes read for everyone else, too, and vice versa if someone marks a message unread, it becomes unread everywhere. Further investigation shows that in these problematic folders, indeed all users directly manipulate the flag of the email (i.e. X marks email Z read, ",S" appears immediatelly in the filename). Anyone knows what I'm doing wrong? I can't seem to find anything different with these problematic folders, ACLs look right etc. Thanks in advance, Tamas

[Dovecot] Custom Flags
by qmail＠top-consulting.net 15 Oct '10

15 Oct '10

I have modified my delivery agent to deposit files in my Maildir already containing custom flags. For example, x is appended for files that are sent from local users, y is for e-mails from Contacts and z is for e-mails from Whitelisted sources. A file will thus be delivered in the Maildir and be called something like: filename:2,yz Also in the Maildir I created a file called dovecot-keywords and have added these 3 flags in there as so: #cat dovecot-keywords 23 Local 24 InContacts 25 Whitelisted I went ahead and erased all the dovecot-uid* dovecot.index* files but Dovecot won't recognize the flags - furthermore, it labels z as 'unknown-25'! - for both old messages or new messages. Here is a bit of IMAP conversation: a02 select inbox * FLAGS (\Answered \Flagged \Deleted \Seen \Draft unknown-25 Whitelisted ) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft unknown-25 Whitelisted \*)] Flags permitted. a03 SEARCH KEYWORD Whitelisted * SEARCH * FLAGS (\Answered \Flagged \Deleted \Seen \Draft unknown-25 Whitelisted Whitelisted) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft unknown-25 Whitelisted Whitelisted \*)] Flags permitted. a03 OK Search completed (0.004 secs). a04 SEARCH KEYWORD unknown-25 * SEARCH a04 OK Search completed (0.004 secs). I know for sure there are files with the z letter in their name in the Inbox. What is going wrong ?

[Dovecot] Limit access to dovecot by domains?
by Jobst Schmalenbach 15 Oct '10

15 Oct '10

Hi. Is there any way to limit access to dovecot by domains. I only need to give access to a well known set of domains, all from Australia and all networks are known and used either from people at home or mobile access (phones, laptops etc). iptables is not possible as e.g. OPTUS does not give away all of the networks mobile phones are connected to. I know some, but not all. It would be much nicer and easier to allow optusnet.com.au bigpond.com.au tpg.com.au and I have given 100% of our users access. I know there is an extra field called "allow_nets", I tried this and failed. I did a search and found that this only works with SQL? Maybe I could include a script that would check the reverse DNS record of a connected IP and then I could filter?????

The problem is when doing doveadm stuff. I do not know ldap (learning as I go). I need to set the uid/guid to vmail (500 in this case if vmail can't be used). Any help would be greatly appreciated. I do not have sfu or rfc2xxx enabled as this requires changing things with Samba 4 that I would rather avoid at the moment.

[Dovecot] Master user sees empty folder list
by interfaSys sàrl 15 Oct '10

15 Oct '10

Hello, I'm having a "path" problem with master users. When logged on as a master user, I can't see the user's folders. I'm trying to use system users as master users, so I'm using something like this: # Master password auth_master_user_separator = * passdb { driver = passwd master = yes pass = yes } # System users passdb { driver = passwd } # Virtualusers users passdb { driver = passwd-file args = username_format=%n /etc/virtual/%d/passwd } mail_location = mdbox:~/mdbox System and virtual users see their folders fine, including the shared namespaces, but as a master user, I see an empty mailbox. I've turned on debugging and watched things like root= and fs= and they're normal. Permissions should be OK since the system user has the same uid:gid as the virtual user. What could it be? Cheers, Olivier

[Dovecot] "doveadm mailbox create" oddities

Hi to all! I’m trying to understand the usage of "doveadm mailbox create”. If I do, as root: # doveadm mailbox create -u __public__ sys/test doveadm(__public__): Error: Can't create mailbox sys/test: Permission denied but if I do: # doveadm mailbox create -u __public__ test every thing is OK. “sys" is a shared maildir folder, that is visible in the client as "#Public/sys”. __public__ is the user that owns Public folders, here is the complete details: userdb: __public__ uid : 10002 gid : 8 home : /var/mail/domainname/__public__ mail : maildir:~/maildir:INBOX=~/maildir/INBOX:LAYOUT=fs:INDEX=~/indexes/ Do I have to add root with proper permissions to ACL?

[Dovecot] Missing ACLOCAL_AMFLAGS ?

dovecot-2.0.5 autoreconf is failing with: [1] $ autoreconf -f -i [...] src/plugins/acl/Makefile.am:11: `module_LTLIBRARIES' is used but `moduledir' is undefined [...] autoreconf-2.65: automake failed with exit status: 1 Also, $ ./configure --help | grep module --with-nss Build with NSS module support (auto) In other words, no moduledir output in configure --help.

[Dovecot] Dovecot chgrp actions on new files/folders
by David Ford 14 Oct '10

14 Oct '10

Timo, I did further study of the user/group permissions. Applying the below patch will make no difference to virtually everyone out there. Those that have default uid/gid ownership won't see any change as the gid already matches so the fchown() action won't be attempted. Those that have sgid will still see the normal expected fchown() enforced by the kernel which becomes a duplicated action by dovecot. In the last case, those with an unknown 3rd party gid were used to seeing fchown() failures and those will now go away. It is only this third group that will see anything change as all other cases are already handled. Anyone who wishes to create new files with another group ID should make their directories sgid or stgid as per normal filesystem ACL semantics. The original net effect of this only turns on an fchown() that will fail and emit numerous error messages. This patch fixes that. Technically the fchown is unneccessary extra code already since any directory that is sgid or stgid will have ownership enforced by the kernel already. I simply made it #if 0 below, the correct patch would be to delete the extraneous block. --- src/lib-storage/mailbox-list.c.orig 2010-09-14 11:03:18.000000000 -0400 +++ src/lib-storage/mailbox-list.c 2010-10-08 13:02:54.000000000 -0400 @@ -450,7 +450,7 @@ } if (S_ISDIR(st.st_mode) && (st.st_mode & S_ISGID) != 0) { - /* directory's GID is used automatically for new + /* directory is sgid, so GID is used automatically for new files */ *gid_r = (gid_t)-1; } else if ((st.st_mode & 0070) >> 3 == (st.st_mode & 0007)) { @@ -460,9 +460,13 @@ } else if (getegid() == st.st_gid) { /* using our own gid, no need to change it */ *gid_r = (gid_t)-1; - } else { + } +#if 0 +#warning this code makes dovecot attempt to chgrp files to wrong ownership + else { *gid_r = st.st_gid; } +#endif } if (name == NULL) {

Hello, testing the lazy_expunge plugin (with 2.0.5), I realized the following effect, which users may not expect/understand: As moving messages from one folder to another has to be done by clients with the IMAP command sequence COPY STORE EXPUNGE, every moved message is also put into the "shadow folder" of the source folder. Maybe it's possible to extend the plugin to optionally hook into the COPY operation, remember it somewhere with the message (simply as special/ configurable IMAP flag?), and then really expunge messages with this flag set. What do you think? I haven't looked into the plugin interface yet. Of course, if a user manually copies a message and deletes the source message later (maybe having the copy deleted inbetween...), the consequence may not be expected either...

[Dovecot] limits to serve sure a number of users
by Schmidt 14 Oct '10

14 Oct '10

Hi, lets say dovcot should serve 1000 user (only imaps) without rejecting a users connection because of to short resources. With version 1.x I had to increase login_max_processes_count = ... With 2.x I'm not sure which parameters I have to set. So Thunderbird 3.x has a default value of 5 connections to cache. "dovadm who" shows quite often 5 connections: userx 5 imap (11154 11152 11158 11156 11150) ... So dovecot has to be configured for 5000 connections/imap-login's? Within 10-master.conf these defaults are shown #default_process_limit = 100 #default_client_limit = 1000 Is it right process_limit is not generally a problem because oldest imap-login process(?) will be closed? (With this expected number of users this value should be increased too.) But what about client_limit? Does it has to be increased to 5000? (There have been some hints by Timo concerning "doveconf -a service" to see how limits will be used for different services.) Any advices? thanks -- Mit freundlichen Gruessen --- Burckhard Schmidt

[Dovecot] userdb syntax
by suzuki 14 Oct '10

14 Oct '10

Hello, I have a question about userdb lookup when using expire-tool. Dovecot version 1.2.15 In dovecot.conf, mail_location = maildir:/var/mail/%u:INDEX=/var/indexes/%u I run dovecot expire-tool, target user's directory becomes executing user's one. According to wiki, userdb setting overrides mail_location. userdb passwd { mail=maildir:/var/mail/%u:INDEX=/var/indexes/%u } With this setting, it seems working. But, there are no examples with ":INDEX=.." setting. Is this syntax right? Regards

[Dovecot] Problem with dovecot-acl was not solved

Problems with acl in dovecot-1.2.15 was not solved! See my configs below. And I see the new bug - still something wrong with configs: cat dovecot-acl: user=t1 lrwsti #user=oper-olegs lrwsti #user=oper-antona lrwsti user=operdss lr #user=operdss lrwsti User t1 can't create subfolers in inbox. He can only create subfolders in the first levels: Inbox test3 test4 Outbox Sent Trash Test1 - test folder created by t1 user Folders test3 and test4 can't be deleted by t1 - why? Owner of the test3 and test4 - annother user, but but with group rights everething is fine. User operdss also can create folders in the same level with such permissions.

[Dovecot] Dovecot 2.0 lock upgrade assertion failure
by Ryan Murray 14 Oct '10

14 Oct '10

Hi! I've now seen this assertion failure from lmtp (most frequent), pop3 (next frequent), and imap (rarely). It didn't start happening until the number of accounts on the server was increased into the 10k-25k range. It happens when index->file_lock is a read lock and mail_index_lock is called asking for a write lock. Dovecot 2.x dies at the assertion on line 62 of mail-index-lock.c If that assertion were removed, it would likely die at the assertion on line 80. Looking at the mail-index-lock.c from dovecot 1.2.15, it looks like the 1.2 series would enter the else case of the "kind of kludgy" block, and end up calling file_lock_try_update(), which seems like what needs to happen. Dovecot 2.x only does a file_lock_try_update() when unlocking, to demote a write lock to a read lock (according to grep). # 2.0.5 (6ea01abfaea9): /etc/dovecot/dovecot.conf # OS: Linux 2.6.35.6 x86_64

[Dovecot] managesieve fileinto folder with international characters
by Edward Carraro 14 Oct '10

14 Oct '10

I have a folder created in dovecot entered by the user as "ññoéé" On the file system it appears as "&APEA8Q-o&AOkA6Q-" (mUTF7) When creating a sieve rule, to file into the folder ññoéé, I am converting the name from UTF8 into UTF7, the rule becomes require ["fileinto"]; if header :contains ["From"] "user(a)domain.com" { fileinto "&APEA8Q-o&AOkA6Q-"; } however when executed, a sieve log is generated saying: failed to store into mailbox '&APEA8Q-o&AOkA6Q-' (&-APEA8Q-o&-AOkA6Q-): Mailbox doesn't exist: &-APEA8Q-o&-AOkA6Q-. If I directly modify the sieve file and place the actual utf8 version of the folder in it require ["fileinto"]; if header :contains ["From"] "user(a)domain.com" { fileinto "ññoéé"; } I get the following error: main_script: line 1: error: folder name specified for fileinto command is not utf-8: ññoéé.

[Dovecot] Outlook FLAGS bug
by qmail＠top-consulting.net 14 Oct '10

14 Oct '10

I believe I have uncovered an Outlook bug. I've searched on the Internet a bit but I didn't find much on this particular topic. Basically it seems that Outlook (I'm using 2007) is overwriting message flags at least when replying to messages. I have seen the following behavior in the dovecot logs, first for only viewing a message, second when replying to a message. urfh UID STORE 65998 +FLAGS (\Seen) 3fxj IDLE DONE ejm4 UID STORE 65998 FLAGS (\Seen \Answered) The second STORE effectively wipes out any other flags on the message and replaces them with \Seen & \Answered I tried the same operation in Thunderbird and it performs properly. Anyone else encountered this bug ? Anyone knows if it's fixed in 2010 ?

[Dovecot] Error on mailbox file
by augustocasagrande＠gmail.com 14 Oct '10

14 Oct '10

Hi! I'm running Postfix 2.2.9 as MTA. I have several mail clients , such as Outlook 2000/xp/2007. The clients comunicate to the MTA using pop3/smtp protocols. I have also installed Webmail Squirrel for the internet users. Squirrel needs an Imap server, so i have utilized Dovecot 1.2.6. To authenticate users , i use pam_winbbind to validate users to my NT domain. Here is my problem : Today i checked my /var/log/mail log and this took my attention : Sep 29 08:25:07 host1 dovecot: imap-login: Login: user=<USER>, method=PLAIN, rip=172.20.22.12, lip=172.20.22.14 Sep 29 08:25:07 host1 dovecot: IMAP(user): mail_location: mbox: mkdir(/home/NT-DOMAIN/user/mail) failed: Permission denied (euid=10188(user) egid=10001(domain users) missing +w perm: /home) Sep 29 08:25:07 host1 dovecot: IMAP(user): Fatal: Namespace initialization failed Here , i assume the user put his user name in CAPS (USER), and that i generating an error. Then Dovecot tries to create the directory /home/NT-DOMAIN/user/mail. In my dovecot.conf file , i have : mail_location = mbox:~/mail:INBOX=/var/mail/%u Now , the log continues : Sep 29 08:25:18 host1 dovecot: imap-login: Login: user=<user>, method=PLAIN, rip=172.20.22.12, lip=172.20.22.14 Sep 29 08:25:18 host1 dovecot: IMAP(user): mail_location: mbox: mkdir(/home/NT-DOMAIN/user/mail) failed: Permission denied (euid=10188(user) egid=10001(domain users) missing +w perm: /home) Sep 29 08:25:18 host1 dovecot: IMAP(user): Fatal: Namespace initialization failed Here the user re-enters the user, now correctly, but the problem persists . Finally , a could see this new log entry : Sep 29 10:50:43 host1 postfix/local[19663]: 50B98441E0: to=<user(a)domain.com>, orig_to=<user(a)domain.com>, relay=local, delay=0, status=bounced (cannot access mailbox /var/mail/user for user user. cannot open file: Permission denied) Here some user tries to send an email to this user , and a permission denied error occurs. Watching the permissions on the file : -rw------- 1 user users 1499655 2010-09-29 02:18 /var/mail/user Maybe some Dovecot process is blocking the file access ? List of Dovecot process: ps ax | grep dovecot 25997 ? Ss 0:07 /usr/sbin/dovecot 15399 ? S 0:02 dovecot-auth 20614 ? S 0:00 dovecot-auth -w How can i fix this issue? Thank you very much ! Augusto

[Dovecot] doveadm doesn't seem to honor mail_location, mail_uid, mail_gid
by Trever L. Adams 14 Oct '10

14 Oct '10

I am adjusting the recommended ldap configuration to match active directory instead of the standard posixaccount layout. The problem is that doveadm seems to ignore mail_uid and mail_gid along with (possibly) mail_location. This is a setup with all virtual users (all ldap, not system accounts). Everything works in postfix and standard dovecot operation, it is only doveadm which doesn't work. Ldap queries return everything but these entries (as they do not exist in AD). These items I have tried setting in the configuration and in environment variables. Any help would be GREATLY appreciated. Thank you, Trever -- "The three Rs of Microsoft support: Retry, Reboot, Reinstall." -- Unknown

[Dovecot] Why deliver+usercheck? deliver+MTA?
by Lukas Haase 14 Oct '10

14 Oct '10

Hi, I successfully configured dovecot using virtual users (and LDAP/AD). deliver is the LDA and verifies if the user exists (as recommended in the WIKI). However, the howtos in the Wiki say *nothing* about the case that the recipients should be verified *before* receiving the messages (prevent backscatter, ...). All configurations in the dovecot-Wiki (postfix and exim) just accept the mails and pass them to deliver. Also, all howtos which I found on the web. If the user does not exist, the mail is bounced because the mail was already accepted by the MTA. Nowadays this is an unacceptable configuration! Is there a special reason why there is no discussion about this? However, as postfix seems to be really too unflexible I have set up exim to handle incoming mail and do the usercheck in the router (with an LDAP query). But now the user is doubled-checked: Once when receiving with exim and a second time in deliver. This is not necessary, so I guess I can disable the LDAP query for deliver and set up a static userdb. Why does the Wiki recommened to verfify with deliver when the user needs to be checked at the MTA anyway? Regards, Luke

[Dovecot] Pigeonhole feature request: automatically copy sieve_global_path (default script) to user's sieve_dir
by Jerrale G 14 Oct '10

14 Oct '10

We have used the great managesieve you have merged together, with sieve, to create pigeonhole. However, when a user creates a custom script through a GUI of ours, the default, as we expected, would be ignored. Maybe you could add a retain_sieve_global=yes|no setting OR be more complex by having the sieve_global_dir copied to the users sieve_dir on first managesieve script save, if another setting to do this was set to yes. This way the administrators can create a skeleton directory and the users can retain the default skeleton settings. Maybe, in the future, you can do, just like the master auth for logging into users' imap accounts, you could have the master=yes allow login to each user's managesieve. Just some suggestions but, until a new feature comes around, I will have a cron job or a imap-login script do the trick. Timo has said that you are a separate developer from dovecot. I just want to thank you for the great job on sieve as well, Kudos, Jerrale G -- Jerrale G. SC Senior Admin

[Dovecot] Qmail+Vpopmail+Mysql+Dovecot 2.x (Notes on a successful conversion)
by Aaron 12 Oct '10

12 Oct '10

SoI had a hell of a time converting my qmail install to dovecot 2.0.5, so I thought I'd pass on what I learned. 1. When using vpopmail, do not use " --disable-many-domains". If you do, you'll need to recompile vpopmail without that setting and use the script found at http://qmailrocks.thibs.com/downloads/scripts/migrate-vpopmail-many-domains to collapse the tables. 2. Switch to mysql authentication. The following snippet works well. driver = mysql connect = host=/var/run/mysqld/mysqld.sock user=vpopmail password=YOURPASS dbname=vpopmail default_pass_scheme = PLAIN password_query = SELECT CONCAT(pw_name, '@', pw_domain) AS user, pw_clear_passwd AS password FROM vpopmail WHERE pw_name = '%n' AND pw_domain = '%d' user_query = SELECT pw_dir as home, 1008 AS uid, 1003 AS gid FROM vpopmail WHERE pw_name = '%n' AND pw_domain = '%d' 3. When integrating Sieve, vpopmail apparently needs to own auth-master and authdb. (example available on request) 4. If coming from maildrop as the LDA, you can put the following in your maildroprc to allow a gentler transition (or to keep maildrop's ability to call external applications) `test -r /usr/libexec/dovecot/deliver` if ( $RETURNCODE == 0) { `test -r $HOME/$EXT/.sieve` if ( $RETURNCODE == 0) { to "| /usr/libexec/dovecot/deliver -d $EXT@$USER" } } 5. When completely switching, you can either replace the .qmail files or use one of the following in qmail/control/defaultdelivery |/var/qmail/bin/preline -f /usr/libexec/dovecot/deliver -d $EXT@$USER |/var/qmail/bin/preline -f /usr/libexec/dovecot/deliver -d ${EXT/-*}@$USER -a $EXT@$USER -- This should allow a final conversion to vpopmail 5.5 (from 5.4.30) with dovecot 2.0.x.. I haven't done that final step yet, but it should now work. Anyhow, I hope this saves someone a few days of head scratching. a.

[Dovecot] POP3 Slow

12 Oct '10

Hi, I am running both IMAP/POP3 services. Recently, the POP3 users started complaining of slow performance. I tried to resolve it by advising them to trim their inbox, but to no avail. Kindly advise as I am not able to resolve this issue. dovecot -n: # 1.0.7: /etc/dovecot.conf ssl_cert_file: /etc/dovecot.cert.pem ssl_key_file: /etc/dovecot.key.pem login_dir: /var/run/dovecot/login

[Dovecot] Dovecot Version 1.2.12 Slow IMAP LIST Question
by Dave Shanefelter 11 Oct '10

11 Oct '10

We are using Dovecot 1.2.12, FreeBSD 8.1 Stable, & SquirrelMail 1.4.21 Our problem is that SquirrelMail works fine inside our Network, but from the outside SquirrelMail times out before it can display the inbox contents. SquirrelMail times out for everyone, all of the time. In troubleshooting we have observed the following: >From the inside, if I telnet into Dovecot IMAP and issue ? LIST "" "*" I get an instant list of my folders. If I do the above from the outside, the LIST command slowly lists 10 - 15 entries and stops, then pauses for what seems to be 30 seconds to a minute, then lists another 10 - 15 entries. After about 5 minutes of this it finally times out. An interesting note is, when it stops listing and pauses, it doesn't stop at the end of a line (folder entry), it stops half way through a line entry. For example, say the folder entry is mailfolder/folder1/folder2, when it stops I see mailfolder/fol I don't think this is a SquirrelMail issue because of the IMAP LIST problem. We have turned on debugging, but the logs really don't show much, just the timeout. Can anyone offer additional troubleshooting to help us track down this issue? Thanks

[Dovecot] ATTN TIMO: Man pages of "deliver"
by Jerrale G 11 Oct '10

11 Oct '10

The man pages of "man deliver" do not explain the "-n" option which is confusing a lot of people as to why mailboxes and mail folders aren't being automatically created; yet, the dovecot wiki's both say to use "-n" in postfix's master.cf which keeps dovecot's lda from automatically creating the folders. People are pulling hair over this! The default should be to not use -n as most will want their directories automatically created. The dovecot wikis, at least wiki1, also do not include the -e option to be more verbose to postfix, on error. Jerrale G.Jerrale G. SC Senior Admin

[Dovecot] login_* options for 1.0.15
by Hugo Monteiro 10 Oct '10

10 Oct '10

Hello all, Although i'm aware that version 1.0.15 is rather old, that's what is used in Lenny, so... Either way, the setup is rather simple, regular dovecot install, with maildirs residing on a "local" ext3 filesystem accessed through FC to a SAN (2Gbps link). The server has 2 cores (with HT), so "almost" 4 cores and 3GB of ram. A couple weeks ago we had a major number of account migrations, from POP to IMAP. We started to notice that in times of peaks, specially after lunch hour, dovecot started to get REALLY slow and closing client connections. A restart to the service was enough to get things working again. Firstly i thought about the max fd number per process, but after checking it turned out it was already rather large, 8192 in our case. I cannot observe any concerning I/O load either. Besides upgrading, are there any suggestions?

[Dovecot] Visible temp files as Imap Folder in INBOX
by Antonio Perez-Aranda 10 Oct '10

10 Oct '10

Hi all, I'm using dovecot-1.2.15 and NFS as storage of Maildir . When I try over IMAP and Evolution to move a mail to another Imap Folder, a file like .nfs000000000159816c0000245 is created and when move operation is finished, the file is deleted. Sometimes, this file isn't deleted and then, you can see a new imap folder called .nfs000000000159816c0000245 when you restart your Evolution or another Imap Client. Is this file created by dovecot? maybe, must dovecot delete this file on login? I think thats is easy fix this with a Post-Login script but I think that dovecot must delete it

2010-10-08 14:37:29 imap <hmarie(a)olypen.com>: Error: Mailbox Removed: Expunged GUID mismatch for UID 1257: ceb413227b55e8aa14cf86ec86f2b652 vs 32b06aa8bc66762bbd6af15228072949 I keep getting a bunch of these, which turn out to be "customer cant delete messages from folder X". I just deleted all dovecot indexes (find -name dovecot* -type f -delete) from all users this morning and this is still happening. Any ideas? Using maildir format
