[Dovecot] questions of how to connect to pop3s
by Scott Berry 12 Nov '10

12 Nov '10

Hello there, I am new to Dovecot and I am using version1.2.12. I have included the dovecot -n output: root@ubuntuSnoopBear:/home/scott# dovecot -n \# 1.2.12: /etc/dovecot/dovecot.conf # OS: Linux 2.6.35-22-generic-pae i686 Ubuntu 10.10 log_timestamp: %Y-%m-%d %H:%M:%S protocols: pop3 pop3s listen: 995 ssl_key_password: nerdie1tech login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/pop3-login login_greeting: pilotalknet.dyndns.org ready. mail_privileged_group: mail mbox_write_locks: fcntl dotlock mail_executable: /usr/lib/dovecot/pop3 mail_plugin_dir: /usr/lib/dovecot/modules/pop3 auth default: passdb: driver: pam userdb: driver: passwd What I need to ensure is that everything is correctly set for a pop3s server. I also need to know how to tell someone how to configure their mail client as the pop3 and smtp server. For example do I say pop.pilotalknet.ldyndns.org and smtp.pilotalknet.dyndns.org? The hostname is: pilotalknet.dyndns.org also is it still possible to check the working of the connection via a telnet connection doing: telnet pilotalknet.dyndns.org:995 or do I have to do something different? what I am achieving with the telnet connection is to ensure the pop server comes up with the greeting from dovecot. Thanks much.

[Dovecot] alternate sendmail binary for sieve redirect OT
by Robert Schetterer 12 Nov '10

12 Nov '10

Hi , this isnt really a dovecot/postfix question in dove lda, there is sendmail_path = someone tried other progs here like mini_sendmail ? http://www.acme.com/software/mini_sendmail/ i.e for using a default from forwarder address when sending redirects by sieve....is a stupid idea? background, some other mail providers use a default sender forwarder mailaddress when redirect this may avoid problems at forwarding with spf etc any other idea to reach this goal, pipe etc? -- Best Regards MfG Robert Schetterer Germany/Munich/Bavaria

[Dovecot] correct syntax for multiple ports
by Kilburn Abrahams 12 Nov '10

12 Nov '10

Hi, What is the correct format to specify multple ports in dovecot 2. With dovecot 1.2 listen = *:143 *:6188 worked fine. I cannot find any mention in the wiki2 about the different combinations of listen, address and port parameters and dovecot complains about the combinations I tried. Does not seem to work 1. inet_listener imap { listen = *:143 *:6188 } 2. inet_listener imap { address = *:143 *:6188 } 3. inet_listener imap { port = 143, 6188 or port = 143 6188 } This start dovecot, but roundcube will not connect on port 143, although Thunderbird will connect on 1432 and 6188 listen = *, :: 1. inet_listener imap { port 143 port = 6188 } Regards K

[Dovecot] Phantom email message
by Marc Perkel 12 Nov '10

12 Nov '10

Got sort of a strange problem on one email account. Everything works fine with Thunderbird/IMAP showing the correct unread message count. But on my DroidX smartphone one of my email accounts always shows one unread message, but I can't bring any unread messages up. It's like there's something there making it think there's a message when there isn't. The email client is K-9 mail Anyone have any ideas?

[Dovecot] --exec-mail
by David Woodhouse 12 Nov '10

12 Nov '10

Most of my IMAP access is achieved by 'ssh $mailhost exec dovecot --exec-mail imap'. I'm testing Dovecot 2.0, and this doesn't seem to work any more — and I can't seem to work out how to make it work. The wiki page at http://wiki2.dovecot.org/Upgrading/2.0 has no mention of it. I looked through the git history to find the commit that broke it and see if I could find the replacement that way, but it was the commit entitled 'Initial commit for v2.0 master rewrite.', and wasn't particularly edifying. Once upon a time in the dim and distant past, I believe I used to run /usr/libexec/dovecot/imap directly. But that doesn't set the environment up correctly, so isn't the right way to do it... is it? -- dwmw2

[Dovecot] setting up Dovecot
by Scott Berry 12 Nov '10

12 Nov '10

Hello there, I am a new user of Dovecot. I am using version 1.2.12. Here is the config file: I attached the dovecot.conf file as a screenshot using dovecot -n because I am blind and haven't quite figured out how to copy from the terminal to Gnome yet. My intentions here are as follows: 1. To allow only pop3s because I want to use ssl for security. 2. I am going to be using fetchmail to grab the mail and give it to dovecot. 3. There will be three people adventually grabbing their mail through pop3s. Another question I have is when you tell someone to configure their mail client through pop3s how does that work as far as the server name meaning like most ISp's have pop.whatever.whatever.? Also I am using a smarthost with postfix to send out the mail through Google how do I tell someone how to configure the smtp server in their mail client such as Isp's such as smtp.whatever.whatever. I am using Windows for two of the clients with Windows Mail on a Vista machine and Windows Mail on a Windows 7 machine and Evolution on a Ubuntu linux machine. Looks to me like everything is copeastetic except for how to log in. The SSL cert file in "/etc/ssl/certs/dovecot.pem" is a bit tricky cause I didn't create the cert so I am not sure of the password but I did try my normal root password. Not sure if that works. Other than this actually Dovecot is quite easy to config.

[Dovecot] Dovecot 2.0.7 Virtual plugin
by Henrique Fernandes 12 Nov '10

12 Nov '10

Well, it seens the virtual plugins is not working correctly or i miss undertood how to configurate it. http://wiki2.dovecot.org/Plugins/Virtual as this wiki says, I should be possible to make an ndeamespace namespace { prefix = virtual/ separator = / location = virtual:~/Maildir/virtual } And in side of ~/Maildir/virtual create virtual folders and inside of those folders create dovecot-vitual. But it does not work. Right if i make this conf, on my imap client it shows a folder called virtual ( the prefix, or whtever i put in there ) and show nothing, only shows something if i create a dovecot-virtual inside of ~/Maildir/virtual/ i would appreciate if someone explain what i am doind wrong. Thanks! my dovecot -n # 2.0.7: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-amd64 x86_64 Debian squeeze/sid mail_debug = yes mail_location = maildir:~/TesteEmail/Maildir mail_plugins = " virtual" namespace { inbox = yes location = prefix = separator = / } namespace virtual { location = virtual:~/TesteEmail/virtual/ prefix = virtual/ separator = / } passdb { driver = pam } ssl = no userdb { driver = passwd } protocol imap { mail_plugins = " virtual virtual" } []'sf.rique

[Dovecot] $MAIL environment variable to override mail_location works in v1.2.16 but not in v2.0.7 for /usr/libexec/dovecot/imap
by Giam Teck Choon 11 Nov '10

11 Nov '10

Hi, For the past day, I have been researching about making dovecot to support mailfront (http://untroubled.org/mailfront/) imapfront-auth natively and able to use mailfront imapfront-auth with dovecot imap v1.2.16 without starting any dovecot related services and no /etc/dovecot.conf file is required. More information about this can be read at: http://lists.untroubled.org/?list=bgware&cmd=showthread&month=201011&thread… However, same trick can't be used for dovecot v2.0.7. First error is /etc/dovecot/dovecot.conf must be exists so I just simply touch /etc/dovecot/dovecot.conf with empty content to bypass that error. I noticed v2.0.7 is not using $MAIL environment variable to override mail_location? I have read the following: http://wiki2.dovecot.org/MailLocation Any idea to override mail_location setting? I have tried various setting of environment variables such as below: --------------------8<----------8<----------8<----------8<--------------------- #!/bin/sh # $MAIL, $HOME, $MAILDIR, $MAILBOX are the same in mailfront # imapfront-auth if [ -n "$MAIL" ]; then # make dovecot imap escape colon by replacing single : to :: export MAIL=maildir:`echo $MAIL | sed 's@:@::@g'` fi export USERDB_KEYS="$USERDB_KEYS mail" # For knowing all env. uncomment the below line and # see /tmp/imapd-log.txt # printenv >>/tmp/imapd-log.txt exec "$@" --------------------8<----------8<----------8<----------8<--------------------- The above script is being placed between imapfront-auth and dovecot imap (/usr/libexec/dovecot/imap). Thanks for any kind assistance. Kindest regards, Giam Teck Choon

Hi, I been using dovecot for awhile and its been solid, however I been having some issues with dictionary attacks. I installed fail2ban and for the most part is working fine.

[Dovecot] dovecot2.0+ldap auth problems
by Antonio Perez-Aranda 10 Nov '10

10 Nov '10

I'm using a config from dovecot 1.2 adapted to 2.0 After update config, and restart dovecot service: If I do a doveadm user user1 then it is found correctly. If I do a doveadm auth user1 then it is ask for the password user, and it's running correctly. But if I tray to login by telnet using IMAP then I get: . login user1 pass1 Connection closed by foreign host. I can see at logs a Info line with: Internal login failre with auth failed It's very odd that with doveadm runs ok and but not with IMAP.

[Dovecot] need to block user by IP address (tried denyhosts, xinetd, iptables etc)
by Tom 10 Nov '10

10 Nov '10

Hi, I am kind of restricted to using packaged versions of software due to company policy, and we have f12 on our mail server with dovecot-1.2.15-2.fc12.i686 package. we have recently had some brute force attacks on the pop3 and imapd and this results in many processes being used for login attempts. Our dovecot is hosted on a Virtual Private Server which restricts access to IPTABLEs and also make a limit on the number of processes that can be running So I can't restrict the attackers IP addresses via IPTABLES, as we don't have access to that. I can't really patch dovecot as we are reliant on the distro packages. I spent some time trying to get dovecot to run under xinetd but had no luck, and I read some reports that it was not possible using recent versions. I was hoping some advice on what avenue I should proceed with to automatically block brute force attacks on the dovecot server, (that dont use iptables) Thanks, Tom

[Dovecot] emails getting mangled when dragging from Exchange account to IMAP shared folders
by Scott Goodwin 10 Nov '10

10 Nov '10

I'm having the most frustrating issue, and I'm at a loss for what is happening. I'm not even sure it is with Dovecot, but that's why I'm posting this here... if it isn't a dovecot issue, maybe someone can get me headed in the right direction? I've posted relevant dovecot and config info at the bottom of this post. Here's the scenario: We recently migrated our email from Postfix+Dovecot+Amavis+SA to Exchange (not my choice, unfortunately). Now, users have to use Outlook (as opposed to before, when they could choose between Outlook and Thunderbird), and have the new Exchange account set up, as well as their old IMAP account, which they still use for shared project folders. So, emails come in to Exchange, then they drag the emails from the Exchange mailbox to the shared branch under their IMAP account, and into the appropriate job folder. Emails to one specific user in my organization (let's call him Roy(a)Ocean.org) is having his emails mangled when dragging certain items from his Exchange mailbox to the IMAP account. I can't reproduce the issue with any other user. Also, this only seems to happens with emails from one other specific domain (let's call them tornado.org) So, in summary, user1(a)Tornado.orgsend an email to Roy(a)Ocean.organd Sue(a)Ocean.org. Both drag the email from their Exchange box into any folder (shared or otherwise) in the IMAP tree. Sue's copy makes it in just fine, while Roy's copy gets mangled. Here's the headers of the resultant email after Roy has dragged it into the shared folder: ======================================== From: "User1" <User1(a)tornado.org> To: "Roy", "Sue" References: <B3457C1920D7A2438CCC19EF2A527293372B11(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A527293372D9A(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A5272933A2C3D(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A5272933A310E(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A5272933A3683(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A5272933A3B97(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A5272933D103B(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A5272933D192F(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A5272933D1B12(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A5272933FD341(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A5272933FD8F8(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A5272933FD9A0(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A5272933FDFDD(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A5272934C8927(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A5272934C8B46(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A5272934C8D76(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A5272934C8D7A(a)abc027.abc.local> <B3457C1920 ======================================== And here's the email body: ======================================== D7A2438CCC19EF2A5272934C8D95(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A5272934C8DB6(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A5272934C8F0D(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A5272935008B5(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A527293500C27(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A5272935011BC(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A527293525B1D(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A527293525D81(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A527293526139(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A527293526416(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A5272935524A6(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A5272935524C9(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A527293589E1C(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A5272935BF6A9(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A5272935E7414(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A5272935E75E2(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A5272935E75E8(a)abc027.abc.local> <B3457C1920 D7A2438CCC19EF2A5272935E75F4(a)abc027.abc.local> <B3457C1920D7A2438CCC19EF2A5272935E800E(a)abc027.abc.local> Subject: RE: Some Subject Date: Tue, 26 Oct 2010 15:11:01 -0700 Message-ID: <B3457C1920D7A2438CCC19EF2A52729364D0A0(a)abc027.abc.local> MIME-Version: 1.0 Content-Type: multipart/alternative; boundary="----=_NextPart_000_0118_01CB7755.52354760" X-Mailer: Microsoft Office Outlook 12.0 Thread-Index: AcrhmOPG84jptRwERxazrnj4Ne2YAQAACMtAAAAjcPAAAAu+gAAAE1hAAAAZWCAAABMaEAAADGzwACO3fdAACN0HsAEpVUrgAPt2jvAAAcrbcABrFxCQAAAXwjAAABGv8AAAI35QAYbDMHAAAPjDYAADNREgAA5XR4AAHoOFcAFtPWTAAIubCCAALwf/MAADBptQACzN6nAAAC61kAAAEN+AAACfkjAAO7MG4AAHLrMQALmKX6AAAUlCcAAAq9SgAAuoo+AAABqqMABXq+FwAD5jAAABYqZYoAOISoLgAAAd//AAAKVPYAApG8DwAAt6dsAAKxpd8AEy9g6gAADrZVAAAE4WgAAlXdkQAPY4tNAAAWY+kAFsS/RgAFtG7qAAAGJT8AAAPLUwAAA2xsAAACamEAAC4ufAADaZyfAAKizZ0AAAZ9EAAAWRHAAAAOgkgAAAUUOgAAQWBBAAij+IkAAE2k1wAAPgAgAANGrwsAACt+wgAC0EW9AAAEDpoAA12EJgAAAyAtAAAyATYAAgyfBQAKS/7/AAAEPWEAABNsTAAAAZujAALLkhkAAwwG5AAAMVt8AAAE3iwAEhzNqgAA8qbEAAIqDaMAA0UTmgAEE0hxAAlsz9IAABAdrAAFIwRcAAZxd5oAAOziPQAJEu45AAOaFlIAAeeCygADwtnbAD9zXHwAApeNOAACk/pfAAABxl0AAAWgGAAAB7d4AACGbyQACNOVmwABF68KAAKuKysAAsiR5gADDcY1AAOMAK8ACO561QABCk+7AAI5IqsAAJGVEgAFjaIkAANWSCQAACuaAwAAAKUQAABugScAAAbmTQAADspwAAzNO+MAAiFH8wAAEA4mAAMv6E0AEtz2wQADWsQHAAO4pvkACIRgpAAAApFcAAABO4UABmP4/QAAEJ/lABNOByMAAF28awAACwfDA= Content-Language: en-us X-OlkEid: C664F3259FA9393D4124CD409B5CAE330696EE82 content-class: urn:content-classes:message This is a multi-part message in MIME format. ------=_NextPart_000_0118_01CB7755.52354760 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit <SNIP> =========================================================================== Obviously, it's breaking the message in the References header, and I've tracked down the following byte sequence at the breaking point: 0D:09:0A:09 ...which is CR,TAB,CR,LF. What puzzles me is why Roy's gets broken here, when the others' do not; they're the exact same email, so you'd think they would all get broken. I can't figure out A) where that byte sequence is coming from (our Exchange server, Tornado.net's exchange server, or one of the two of our external spam filtering service... they use BigFish.com, and we use MxLogic), or B) if that's even the issue. I've rebuilt Roy's entire machine, reconfigured Outlook from scratch, still happening. When he logs onto another machine and sets up his Exchange account on another outlook, it still happens. Our Exchange administrator (I don't have access to Exchange) says there is nothing wrong with his Exchange account, for what it's worth. I don't expect anyone to have the solution here, since there are many variables, and there is other info that would probably be needed. What I DO want is to be pointed in the right direction on how I might track this down. For example, what is the path that this mangled email would take in this case? Even with full logging in Dovecot and postfix, I can't see any info on the path that this email follows in our system, and where it might be getting mangled. Does it actually go through the same path as an email that was actually sent to the IMAP account, or is it different when it is dragged in from another account in the same mail client? Is this more likely a problem with Postfix, or Sieve, or....? (I've disabled Amavis and SA to get them out of the picture, and same problem).

Re: [Dovecot] Todays Performance Data for 2.0.x

Dividing the imap processes's system CPU usage by number of imap processes: imap : 0.478872 of 975 imap : 0.460797 of 1242 imap : 0.409641 of 2482 imap : 0.424035 of 4711 imap : 0.488494 of 6148 imap : 0.56809 of 7031 imap : 0.734864 of 6965 So it's about 0.5 seconds of system CPU per imap login. I also get something like 0.3 seconds of system CPU per imap login on my system. Also setting: service imap { service_count = 0 } (i.e. reuse imap processes) reduced the system CPU usage to almost nothing. But if you use different UIDs for different users you can't do that. So, yeah, looks like the process initialization is wasting time somewhere. I'll look further into it.

[Dovecot] how can I use different LDAP config for LDA and AUTH?
by Zhou, Yan 09 Nov '10

09 Nov '10

Hi there, I am setting up mail client with DoveCot and, at the same time, use Postfix to deliver message to DoveCot via LDA. I want to support having user name "jsmith" on my mail client, and that gets all messages for email address: dovecotdemo@domain. (The user name is different from what is in the email address). In addition, all user & password look up is handled by LDAP. Here is my problem: 1. my mail client will login as "jsmith", that goes through LDAP to find mail/home/password for this user. (this matches user name) 2. When postfix delivers a message, DoveCot LDA will find a match with email address "dovecotdemo@domain", it goes through the same LDAP configuration. (this matches email address). You can see the two search criteria are different, but by default they use the same passdb and userdb configuration. I want to use a different LDAP config. file for LDA to use, where it will match the email address (so that it is different from the default dovecot-ldap.conf, which is used by authentication). DoveCot Deliver can specify a separate configuration file with "-c", so I tried that. But I cannot get LDA to use a different configuration. Would should be an example of config file used by Deliver? Anyone running into this problem? Thanks, Yan NOTICE: This email message is for the sole use of the intended recipient(s) and may contain confidential and privileged information.

[Dovecot] Expunge -A cannot find users
by Kilburn Abrahams 08 Nov '10

08 Nov '10

Hi List, If I use doveadm expunge in this format expunge will delete the email doveadm expunge -u test(a)planetseafood.com mailbox Archive ON '8-Nov-2010' But in this format doveadm expunge -A mailbox Archive ON '8-Nov-2010', it will list all the users in the database and display the following and no messages are expunged. doveadm(test@planetseafood.com@planetseafood.com): Info: User no longer exists, skipping. The iterate_query = SELECT username AS username, domain FROM mailbox which is correct for the DB layout. I am not using the expire plugin. Is this a permissions issue? Thanks Kilburn

[Dovecot] Estimación de horas del cambio a Dovecot 2.0
by Antonio Perez-Aranda 08 Nov '10

08 Nov '10

Actualmente tenemos dovecot 1.2.15 que ha demostrado ser bastante estable, pero con el que podemos tener problemas de corrupción en ficheros de índices de Dovecot (dovecot-uidlist). Este problema, podría llegar a ocasionar la descarga de todos los correos desde el cliente del usuario. En Dovecot 2.0 tenemos una mejor gestión sobre NFS mediante un nuevo sistema llamado director. Con este director se consigue que dovecot haga a su vez de proxy/balanceador e intente direccionar las conexiones de un usuario a un mismo servidor si este permite conexiones. En resumen, conseguimos evitar escrituras "concurrentes" sobre cachés de NFS que podrían ocasionar corrupción en determinados índices de dovecot. Para este cambio básicamente deberíamos repetir ciertas pruebas que hemos realizado para dovecot 1.2 así como ciertas tareas. 1. Actualizar configuración 2. Actualizar plugin TrataSPAM (MarcaSPAM/DesmarcaSPAM) Usando skel creado por Timo durante las sesiones de Málaga. 3. Pruebas de tiempos de indexado con SQUAT 4. Búsquedas concurrentes. 5. Pruebas de IMAP IDLE. 6. Migración { Keywords, suscriptions, flags, status...} 7. Condiciones de estrés. 8. Actualizar Doc. En una primera estimación. El total de estas tareas no debería superar las 45-50 horas. A cambio obtendríamos: 1. Un mejor soporte por parte de Timo. 2. doveadm para realizar búsquedas, gestión del director, pruebas de depuración... 3. Mejoras en el comportamiento ante storage en NFS. 4. Mejoras en la coordinación con SOLR para cuando comencemos con el buscador avanzado con ficheros adjuntos. 5. Mejoras para conexiones concurrentes. La razón por la que no empezamos directamente con dovecot 2.0 es porque no preveíamos que fuera relativamente estable en poco tiempo. Observando la lista de correos y después de la conversación con Timo, la última release de dovecot 2.0 es lo suficientemente estable como para usarse en sistemas de producción. Si lo creéis necesario, podemos organizar una reunión para tomar la decisión, aunque sí que esta reunión debería ser para esta semana o a principios de la siguiente.

[Dovecot] dovecot + sieve

Hi, In ower mail system we use postfix and dovecot v1.2.10 with sieve plugin and i think is work fine but..... i need to have access to variables values like in these test script require ["enotify", "variables", "envelope"]; keep; notify :importance "1" :message "TEST SIEVE ${from}: ${subject}" "mailto:i_not_exist@hotmail.com"; but when i receive message, the values for "${from}" and "${subject}" are empty. i don't know the reasons about these (i'm some lost with these issue).. if help ... i put in master.cf (postfix) these value for dovecot delivery: dovecot unix - n n - - pipe flags=DRhu user=mail:mail argv=/etc/dovecot/libexec/deliver -f ${sender} -d ${recipient} ¿is here the problem or what could be? thanks in advance! *Salu2 ;)*

Summarising mail standards (WRT headers) There is a limit of 4096 characters per line. If Outlook is breaking at less than that it's a bug. If the References: line is longer than that then it should have been truncated by the sending MUA - there's no provision for multiline References headers (which are a non-standardised import from Usenet anyway).

[Dovecot] Last login tracking with login_executable
by Denny Lin 07 Nov '10

07 Nov '10

Hi, I'm using Dovecot 1.2.14, and I've read PostLoginScripting on the wiki. Is there any way to make Dovecot use the same username/password for database access as userdb and passdb queries? Specifying the password with -p doesn't seem like a good idea, so I'm wondering if it can be handled by Dovecot directly. Or is it possible to track last logins with a plugin similar to quota? -- Denny Lin

[Dovecot] Keep a copy of email.
by Henrique Fernandes 07 Nov '10

07 Nov '10

Can dovecot-lda, keep a copy of any email that it receives in a diferente folder ? Like if user(a)domain.com get an email. It goes to user(a)domain.com inbox and goes to other folder..diferente that his mailboxes ? I want this with all users. Can it be done ? If not, does any one have any ideia how could it be done ? We are having serius problems with backups, with this we gona be able to at least save one or two days of each emails, than rotate them again. I though about using postfix always_bcc, but would be everyones emails only in one account. Though in migh use sieve for filter this acount and separete it for each folder.. but i don't guess sieve could get a parameter from the email to make a filter.. or can it ? like, if email from user2(a)domain.com it goes to user2 folder, but this user2 would be variable, otherwise i have to create a sieve too bigm and would work i guess. Well, i am open to ideas. Thanks! []'sf.rique

[Dovecot] Getting plugin config by user
by Alex Baule 05 Nov '10

05 Nov '10

There is a native way to set/get a configuration to one plugin, to various users ? Like this: my_plugin{ user_a=configurations user_b=configurations user_...... user_z=configurations } I Have plugin and it can be enable/disabled by user. And i have a lot of users, like 10 m. i think if i do like this: my_plugin { configurations=user_a,user_b,user....,user_z } Can get much memory to read every line of configuration... Tks !

[Dovecot] sdbox-format and sa-learn(spamassassin)

Hello, is it somehow possible to use sa-learn on sdbox-mailboxes?

I know the antispam-Plugin, but until now no success, to get it running. So I think about an way, to learn via sa-learn on an file which i can process. Regards Ingo

[Dovecot] automatic un-subscribe ?
by Per Jessen 03 Nov '10

03 Nov '10

Is there a way for an unsubscribe from a previously (auto-)subscribed folder? I'm building an email archiving system, and archived mails are organized by annum. A user will have e.g. 3 years of archive available. Currently that would mean this user would be auto-subscribed to private folders named 2007, 2008, 2009 and current. Starting January 2011 though that would change to 2008, 2009, 2010 and current. Is there a way of auto-unsubscribing 2007 ? /Per Jessen, Zürich

by Alex Baule 03 Nov '10

03 Nov '10

Hi Timo and Everyone.... There is a way to know when a folder it's been deleted ? And if this folder is empty ? Let's explain why... I intercept the expunge function, to treat my files expunged, but when i expunge a folder, this function it's not called, and my emails don't get my treatment to be expunged. Basically i need to do something like this: It's empty ? No --> return OK but Dont Delete folder, because it's not empty. Yes --> Return OK and Delete the Folder to be expunged. Tks !

[Dovecot] Virtual inbox folder bug
by Antonio Henrique Oliveira 03 Nov '10

03 Nov '10

Hi all, I've been using dovecot as our internal mail server for quite some time. It works very well. Each of our mailboxes have 1000+ messages (some have more than 4-5000 messages). I have recently started using virtual folders and, using an adaptation of an example script in the dovecot site (http://wiki.dovecot.org/Plugins/Virtual) to have a virtual folder changed to act as inbox. All of my email is delivered in some folder other than the real inbox via sieve scripts. My inbox is, therefore, a virtual folder, which only displays the unread emails on all the folders in the account. Everything works fine *except* that, when I mark an email as read or when I open an email directly on the inbox, it does not disappear from the inbox (as it should since it is not unread after being open or being marked as read). I'm not sure if this is a bug, a "feature", or a misconfiguration.... :) I'm using dovecot 1.2.13 on Debian Etch (installed using the backports repository). Attached is the file with the output of "dovecot -n", the script for the virtual folder and the custom login script to change the virtual folder to act as the inbox. I'm using Thunderbird 3.1.6 on Windows XP SP3 as the main mail client and also using an Android phone (Samsung Galaxy) to access the same account. Regards, -- Anto'nio Henrique A.

[Dovecot] Dovecot 1.1.20 on OS X - ACL deliver Problem
by R. Svejda 03 Nov '10

03 Nov '10

I am trying to create an archive postoffice by bcc all e-mail from the "real" mail server to an existing OS X server and by setting all ACL to read-only. Problem: deliver reports: "Fatal: mail_full_filesystem_access=yes is incompatible with ACLs" It seems, that the failure is independent of the existence of an ACL file. I cannot change machines (must be OS X) and I do not like to compile anything on that box (but I could re-configure stuff). Can anybody help how to get around this error with existing hard and software?

I am using a postfix virtual users/domains setup (hosting multiple domains with multiple users), with SQL lookup. What I need is to be able to define a mailing list on a given domain, so that mails received on that one address will be sent to a multiple of users, with the sender e-mail changed to be the address of the mailing list, so replies are sent straight to the list, and not the original sender. >Otherwise, mailman isn't hard to setup. and you >get the benefits of a "real" list manager.

[Dovecot] Wrong protocol in socket (director-doveadm vs director) ?
by Edward Carraro 02 Nov '10

02 Nov '10

I just noticed this error in my logs: director: Error: doveadm not compatible with this server (mixed old and new binaries?) director: Error: director(10.161.192.28:541/right): Wrong protocol in socket (director-doveadm vs director) The first error I removed by changing director_doveadm_port = 541 to director_doveadm_port = 542 Not really sure why that fixed it. The second error I don't know how to clear. I found this thread, http://dovecot.org/pipermail/dovecot/2010-July/051022.html but it didn't work for me. If I create a new service for dovecot-doveadm service director-doveadm { inet_listener { port = 542 } } Then I get a new error saying: service(director-doveadm): executable is empty here is my original 10-director.conf file (i'm using dovecot 2.0.6) director_doveadm_port = 541 service director { unix_listener login/director { mode = 0666 } fifo_listener login/proxy-notify { mode = 0666 } unix_listener director-userdb { mode = 0600 } inet_listener { port = 541 } } service imap-login { executable = imap-login director } service pop3-login { executable = pop3-login director } service managesieve-login { executable = managesieve-login director } protocol lmtp { auth_socket_path = /usr/local/var/run/dovecot/director-userdb passdb { driver = static args = proxy=y nopassword=y port=24 } }

[Dovecot] Dovecot 2.0.5 crash when It cannot remove maildir

This is scenario that cause segmentation fault in my Dovecot. Maybe I do something wrong, but I don't know what... We run: mailbox_delete mailbox_delete do: mailbox_open(box) < 0 and after we have: box->v.delete(box) which run index_storage_mailbox_delete index_storage_mailbox_delete do: mailbox_close(box); and now mailbox is closed (this close box->view and mailbox open) Try to delete folder, but can't do this... example becaus it is system folder, or NFS failure... set error message and return -1. Now we are returning to mailbox_delete. And we have: if (ret < 0 && box->marked_deleted) and this is true mailbox_mark_index_deleted(box, FALSE) if (box->marked_deleted && del) this is false mail_index_transaction_begin(box->view, trans_flags); mail_index_view_ref(view) and segmentation fault, because view is 0x0 #0 mail_index_view_transaction_ref (view=0x0) at mail-index-view.c:81 #1 0xb7ef3214 in mail_index_transaction_begin (view=0x0, flags=MAIL_INDEX_TRANSACTION_FLAG_EXTERNAL) at mail-index-transaction.c:268 #2 0xb7eb7a73 in mailbox_mark_index_deleted (box=0x80c8268, del=false) at mail-storage.c:682 #3 0xb7eb80a9 in mailbox_delete (box=0x80c8268) at mail-storage.c:757 #4 0x0805001f in cmd_delete (cmd=0x8095978) at cmd-delete.c:46 #5 0x0805625c in client_command_input (cmd=0x8095978) at imap-client.c:741 #6 0x0805630b in client_command_input (cmd=0x8095978) at imap-client.c:791 #7 0x0805646d in client_handle_input (client=0x8095390) at imap-client.c:857 #8 0x08056f1f in client_input (client=0x8095390) at imap-client.c:908 #9 0xb7e6f110 in io_loop_handler_run (ioloop=0x806c370) at ioloop-epoll.c:212 #10 0xb7e6da98 in io_loop_run (ioloop=0x806c370) at ioloop.c:350 #11 0xb7e5b26a in master_service_run (service=0x806c2c0, callback=0x805f800 <client_connected>) at master-service.c:496 #12 0x0805f6da in main (argc=1752462689, argv=0x73616d2d) at main.c:358 This is Dovecot error or I do something wrong? -- Len7hir

[Dovecot] Help with implementing quota warning
by Joy 02 Nov '10

02 Nov '10

Dear All, I am using the latest version of doveot-2.0.6 and using dovecot-lda to deliver mail in to Maildir. I have successfully implemented the global quota as well as per user quota using ldap for storing per user quota. Now i am trying to send warning message when user exceed quota limit of 80% and 95% but unable to implement the same. Here is the output of doveconf -n # 2.0.6: /usr/local/dovecot/etc/dovecot/dovecot.conf # OS: Linux 2.6.35-22-generic i686 Ubuntu 10.10 base_dir = /var/run/dovecot/ disable_plaintext_auth = no hostname = mail.example.net lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes listen = * log_path = /var/log/imap login_greeting = IMAP4 and POP3 server ready to serve you. mail_location = maildir:~/Maildir mail_plugins = " acl quota" passdb { args = /usr/local/etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { acl = vfile:/usr/local/dovecot-acl/acl:cache_secs=3600 autocreate = Sent Items autocreate2 = Drafts autocreate3 = Spam autocreate4 = Deleted Items autosubscribe = Sent Items autosubscribe2 = Drafts autosubscribe3 = Spam autosubscribe4 = Deleted Items quota = maildir:User quota quota_rule = *:storage=1G quota_warning = storage=95%% /usr/local/bin/quota-warning.sh 95 %u quota_warning2 = storage=80%% /usr/local/bin/quota-warning.sh 80 %u } postmaster_address = admin(a)example.net protocols = imap pop3 service imap-login { inet_listener imap { port = 143 } } service pop3-login { inet_listener pop3 { port = 110 } } service quota-warning { executable = script /usr/local/bin/quota-warning.sh unix_listener quota-warning { user = vmail } user = dovecot } ssl = no userdb { args = /usr/local/etc/dovecot/dovecot-ldap.conf.ext driver = ldap } protocol lda { mail_plugins = " acl quota" } protocol imap { mail_plugins = " acl quota autocreate imap_acl imap_quota" } protocol pop3 { mail_plugins = " acl quota" } Here is quota-warning.sh content #!/bin/sh PERCENT=$1 USER=$2 cat << EOF | /usr/local/dovecot/libexec/dovecot/dovecot-lda -d $USER -o "plugin/quota=maildir:User quota:noenforcing" From: postmaster(a)teamgenesys.net Subject: quota warning Your mailbox is now $PERCENT% full.

[Dovecot] Dovecot 2.0.5 - multiple auth processes.
by Marek Miska 02 Nov '10

Hi. On Dovecot 1.2.x it is possible to run multiple auth daemons. Is it possible on dovecot 2.0.x ? (Setting "process_min_avail" for auth service gives this error message: "doveconf: Fatal: Error in configuration file /etc/dovecot/dovecot.conf: service(auth): process_min_avail is higher than process_limit") Sample configuration for dovecot 1.2.8: auth default { count = 10 mechanisms = plain passdb ldap { args = /etc/dovecot/dovecot-ldap.conf } userdb ldap { args = /etc/dovecot/dovecot-ldap.conf } user = root } auth lda { mechanisms = plain passdb ldap { args = /etc/dovecot/dovecot-ldap.conf } userdb ldap { args = /etc/dovecot/dovecot-ldap.conf } user = root socket listen { master { path = /var/run/dovecot/auth-master mode = 0666 } } }

[Dovecot] Help Dovecot / vpopmail auth process...
by postmaster＠cyborspace.com 02 Nov '10

02 Nov '10

Please forgive my previous posts, sending mail manually since i cant get the auth to work. Thought i had the body cut and pasted correctly. I am pulling my hair out, i think I know what is wrong - i just cant find out how to fix it. Using Debian - lenny it appears that the auth process - is not looking for / seeing the proper file or database for the lookup. i would like it to point to the cdb file stored ~/domains/%d/ <---- assuming the %d = domains - and the file would then be vpasswd.cdb......

[Dovecot] Namespace subscription issue
by Brad Davidson 02 Nov '10

02 Nov '10

I'm a little confused about how public namespaces work with subscriptions. If I set subscriptions=no and subscribe to the folders, the subscription entries go into the user's private subscription file and that's fine. However, I am unable to pull their status with the LIST-EXTENDED extension. Normal listing works OK: A0004 LIST "" "*" RETURN (STATUS (MESSAGES UNSEEN)) * LIST (\NonExistent) "/" "Public" * LIST () "/" "Public/Public One" * STATUS "Public/Public One" (MESSAGES 0 UNSEEN 0) * LIST () "/" "Public/Public One/Sub 1" * STATUS "Public/Public One/Sub 1" (MESSAGES 0 UNSEEN 0) * LIST () "/" "Public/Public One/Sub 2" * STATUS "Public/Public One/Sub 2" (MESSAGES 0 UNSEEN 0) * LIST () "/" "Public/Public Two" * STATUS "Public/Public Two" (MESSAGES 0 UNSEEN 0) * LIST () "/" "Public/Read-only" * STATUS "Public/Read-only" (MESSAGES 1 UNSEEN 0) A0004 OK List completed. Listing SUBSCRIBED (or LSUB) fails: A0003 LIST (SUBSCRIBED) "" "*" RETURN (STATUS (MESSAGES UNSEEN)) * LIST (\Subscribed) "/" "Public/Public One" * NO Mailbox doesn't exist: Public.Public One * LIST (\Subscribed) "/" "Public/Public One/Sub 1" * NO Mailbox doesn't exist: Public.Public One.Sub 1 * LIST (\Subscribed) "/" "Public/Public One/Sub 2" * NO Mailbox doesn't exist: Public.Public One.Sub 2 * LIST (\Subscribed) "/" "Public/Public Two" * NO Mailbox doesn't exist: Public.Public Two * LIST (\Subscribed) "/" "Public/Read-only" * NO Mailbox doesn't exist: Public.Read-only A0003 OK List completed. If I set subscriptions=yes it works OK, but then the subscriptions are shared unless I override SUBSCRIPTIONS in the mail location. Is this working as designed? Here's what I ended up doing - is there a better way? namespace { inbox = yes location = prefix = separator = / type = private } namespace { hidden = yes list = no location = maildir:%h/Maildir prefix = ~/mail/ separator = / type = private } namespace { type = public separator = / prefix = Public/ location = maildir:/var/mail/public:INDEX=~/Maildir/public:SUBSCRIPTIONS=~/Maildir/ public/subscriptions subscriptions = yes } --- Brandon 'Brad' Davidson Virtualization Systems Administrator University of Oregon Information Services (541) 346-8098 brandond(a)uoregon.edu

[Dovecot] What causes the quota information to get updated?
by Patrick Westenberg 02 Nov '10

02 Nov '10

Hello, if new mails arrive, the quota information is updated and reported via imap immediately. However, after deleting a message, nothing happens. Even if I delete all messages and the mailbox e.g. was over quota, new mails won´t be accepted because the mailbox is over quota. Is this the way it should be or a misconfiguration? # 2.0.4: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 2.6.26-2-amd64 x86_64 Debian 5.0.5 auth_mechanisms = plain login log_timestamp = "%Y-%m-%d %H:%M:%S " mail_debug = yes mail_gid = vmail mail_location = mdbox:~/mdbox mail_plugins = quota mail_uid = vmail managesieve_notify_capability = mailto managesieve_sieve_capability = comparator-i;octet comparator-i;ascii-casemap fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date namespace { inbox = yes location = prefix = INBOX. separator = . type = private } passdb { args = /usr/local/etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { quota = dict:User quota::file:%h/mdbox/dovecot-quota quota_rule2 = INBOX.Trash:storage=+50M quota_warning = storage=95%% quota-warning 95 %u quota_warning2 = storage=5%% quota-warning 5 %u sieve = ~/.dovecot.sieve sieve_global_path = /usr/local/etc/dovecot/sieve/default.sieve } protocols = imap sieve service imap-login { service_count = 1 } service managesieve-login { inet_listener sieve { port = 4190 } inet_listener sieve_deprecated { port = 2000 } service_count = 1 } ssl = required ssl_cert = </etc/ssl/certs/imap_wk-serv_net.crt ssl_key = </etc/ssl/certs/imap_wk-serv_net.key userdb { args = /usr/local/etc/dovecot/dovecot-sql.conf.ext driver = sql } protocol imap { mail_plugins = $mail_plugins imap_quota }

[Dovecot] LDAP acl_groups - can multivalue LDAP be used
by ian+dovecot＠comtek.co.uk 02 Nov '10

02 Nov '10

Hi, Is there some kind of way to get acl_groups out of LDAP without having to maintain an entry with a list of groups 'a,b,c' and so on? Our groups have a list of 'member' attributes with CNs pointing at users. Ideally there would be a way to look this up directly. Alternately I could perhaps use an OpenLDAP overlay to show 'group' attributes for each user's ldap entry. I would then like to be able to tell it to get all 'group' attributes and comma-separate them. The best option I've seen so far is something like http://www.dovecot.org/list/dovecot/2010-March/047731.html which seems to involve a completely separate LDAP session from a login script. Thanks in advance for any help, Ian

[Dovecot] problem with folder creation
by John Watson 02 Nov '10

02 Nov '10

I am running dovecot 1.2.12 on Free BSD 8.1. We also have postfix and a version of squirrelmail for the UI. We are using MySql database to store the email account info. I wrote a script to insert about 100K users into mysql. Those accounts seem to work well and I'm able to see things like 'Drafts', 'Trash' and 'Sent'. Now I am working on code to create new accounts - one at a time. The accounts get created and I can send and receive email from them but when I go go Drafts, Sent or Trash I get an error that says: ERROR: Could not complete request. Query: SELECT "INBOX.Drafts" Reason Given: Mailbox doesn't exist: INBOX.Drafts When I go out and look at the mailbox folders for these users I only see "cur", "new", and "tmp" whereas on other accounts that work well I also see things like INBOX.Drafts etc. I have examined the sql that is inserting the accounts in bulk versus the one by one case and can not see any differences (other than a new mailbox name/password etc). Everything that I'm reading online indicates that Dovecot should just create these extra folders on the server and there is really nothing for either an admin or a user to do. Does anyone have any more information on this? Thanks in Advance John Watson

[Dovecot] Doveadm-Expunge v2.0.5
by Kui Zhang 02 Nov '10

02 Nov '10

Hello Few questions regarding Doveadm-Expunge. 1. I have lazy expunge configure with this name space: .EXPUNGED Storage type: mdbox doveadm -Dv expunge -u user@domain mailbox ".EXPUNGED/*" savedbefore 7d I get some interesting outputs. doveadm(user@domain): Debug: expunge: box=.EXPUNGED/INBOX/mon uid=791 doveadm(user@domain): Debug: expunge: box=.EXPUNGED/INBOX/mon uid=792 doveadm(user@domain): Debug: expunge: box=.EXPUNGED/INBOX/mon uid=793 .... doveadm(user@domain): Info: expunge: box=INBOX/mon, uid=196, msgid=<E1OwJm4-0000j4-1l@domain>, size=1856 doveadm(user@domain): Info: expunge: box=INBOX/mon, uid=197, msgid=<E1OwJmP-0000pr-4M@domain>, size=1756 doveadm(user@domain): Info: expunge: box=INBOX/mon, uid=198, msgid=<E1OwJpP-0002Hp-Pu@domain>, size=1810 doveadm(user@domain): Info: expunge: box=INBOX/mon, uid=199, msgid=<E1OwJqw-0002y7-AF@domain>, size=1766 doveadm(user@domain): Info: expunge: box=INBOX/mon, uid=200, msgid=<E1OwJud-0004ba-Fe@domain>, size=1890 ... So what is the diff between "Debug: expunge" and "Info: expunge". Anything done to "Info: expunge"? I am assuming the "debug: expunge" are the only entries with actions. And "Info: expunge" is not doing anything. I ran doveadm purge -u user@domain after. I did not notice any missing emails. Sorry for the trivial question, I just want to make sure not mail would disappear, all of sudden. 1.A. Would not it be faster not to enumerate for large mailboxes (30-40GB - Maildir)? Is it possible to add a switch, to select single user expunge behavior? ref: http://www.mail-archive.com/dovecot@dovecot.org/msg32322.html 2. Also. expunge does not appear to remove empty mailboxes, is this a bug or intentional? If intentional, why? Any way to automated removal of empty mailboxes? Thank you KuiZ

[Dovecot] Maildir and Index max size
by Emmanuel Gonzalez Carmona 02 Nov '10

02 Nov '10

Hi all, I was wondering if any of you had configured a Mailbox with >= 5GB of space with LDA indexing enabled on it. I'm trying to understand the limits to Dovecot (if there are any) regarding maildirs/indexes max size. Reading in the documentation i didn't found anything concerning this issue. Any experience with this? Emmanuel Gonzalez Carmona

[Dovecot] Differences between IPv4 and IPv6 authentication
by Tony Meyer 02 Nov '10

02 Nov '10

Hi, I have Dovecot listening on both IPv4 and IPv6, and can connect on both interfaces, but cannot authenticate over IPv6, using exactly the same credentials as IPv4. I assumed that the same authentication mechanisms would be used, regardless of the protocol being used - are there differences somewhere? For example: ~$ telnet server1.teststable.simplyspamfree.com 143 Trying 2a01:4f8:100:12c1:bc:28:b2:34... Connected to server1.teststable.simplyspamfree.com.

[Dovecot] fts_solr on debian lenny dovecot 1.2.15
by a＠test123.ru 02 Nov '10

02 Nov '10

Hello, I cannot run FTS SOLR engine. OS is debian lenny. I re-compiled debian package (from backports) with --with-solr option. Dovecot loads fts_solr plugin. I know that it loads plugin because if I remove lib21_fts_solr_plugin.so, dovecot does not start. But it does not attempt to communicate with SOLR. Simple check: stop solr tomcat, and open 8080 port in netcat: $nc -l -p 8080 dovecot never tries to connect to 8080 when I search message by IMAP. I removed indexes, it did not help.

[Dovecot] Problem with excel and word attachements ?
by Frank Bonnet 02 Nov '10

02 Nov '10

Hello We are in (random) troubles with some emails that contains word and excel attachements ( others attachements are OK ) I don't really think Dovecot is implied in this trouble but I want to be sure ... The problem is users cannot open attachements from their clients ( thunderbird 3.1 ) it stays in "download" mode until timeout. Maybe there is a Dovecot's workaround to solve that boring problem ? Thank you

[Dovecot] Linux Bootup: Dovecot Failure
by Christopher Metter 01 Nov '10

01 Nov '10

Hi there! Im using a dovecot system in combination with postfix(with dovecot lda) and ldap. Till today it ran well, but before switching to live, i did some system updates and at the reboot following message occured: Starting IMAP/POP3 mail server: dovecoUnexpected first line <localhost: timed out, nothing received> (First it says: "Starting IMAP/POP3 mail server: dovecot ", but then something fails and overrides the "t" of dovecot with "Unexpected.... ") I don't know when this error occured first, but it only goes away if i delete dovecot from autostart at bootup (by renaming dovecot-file in /etc/rc2.d/ ) No error shown in /var/log/mail.* or syslog Apart from showing this message, system is running perfectly. Users can login, receive their mail and produce new mail-traffic with postfix ;) ATM i really dont know what to do, im near switching to live status of this system and that message is annoying me. Didnt find any information on the net. Hope someone on this list can give an helpful advice Dovecot version: 1.2.15 Greetings from Germany, Christopher Metter dovecot -n: http://nopaste.info/0447cd09ba.html Boot log: http://nopaste.info/index.html

[Dovecot] Mailing lists in Dovecot?
by Peter Reinhold 01 Nov '10

01 Nov '10

Hi all, I was wondering if anyone could recommend a simple mailing list manager that plays well with a Postfix/Dovecot setup, with virtual domains? It really just has to be very simple, basically, an alias would work, if I could rewrite the sender address/name, and I don't really need the possibility for users to subscribe via e-mail based commands. I've looked at the XEXEC plugin as a possible method of doing this, via some Perl perhaps, anyone has any experience using this they would like to share? Mvh, Peter Reinhold / peter(a)reinhold.dk

[Dovecot] auth child abort - "Requested NTLM scheme, but we have only SSHA256"
by LEVAI Daniel 01 Nov '10

01 Nov '10

Hi! I noticed these messages in my logs. It seems that the user checked the "encrypted password" in her outlook or something, and wants NTLM auth. I'm storing all the passwords as SSHA256, and when the user tries to auth, this happens: => dovecot.info auth: Info: password(<username>,<user_ip>): Requested NTLM scheme, but we have only SSHA256 auth: Debug: sql(<username>,<user_ip>): query: SELECT username AS user, password, home AS userdb_home, uid AS userdb_uid, gid AS userdb_gid, userdb_import AS userdb_userdb_import FROM userdb WHERE auth_username = '<username>' AND login = 'enabled' => dovecot.log auth: Error: sql(<username>,<user_ip>): Multiple password values not supported auth: Panic: file passdb-sql.c: line 113 (sql_query_callback): assertion failed: (password == NULL || scheme != NULL) master: Error: service(auth): child 10679 killed with signal 6 (core not dumped - set service auth { drop_priv_before_exec=yes }) Is this an error condition if I store the password in a different scheme than what user is requesting?

[Dovecot] Testing pop3/imap4 and mdbox corrupted indexes?
by Odhiambo Washington 01 Nov '10

01 Nov '10

I have two questions: 1. What method/tool (other than a MuA) can I use to test my Dovecot setup from Windows CLI when ssl is enabled? I have tried connecting to to the pop3/imap4 services from a Windows PC but here is what I get: [pop3] +OK Dovecot-2.0-sis ready. user wash(a)domain.co.ke -ERR Plaintext authentication disallowed on non-secure (SSL/TLS) connections. [imap4] OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE STARTTLS LOGINDISABLED AUTH=DIGEST-MD5] Dovecot-2.0-sis ready. login wash(a)domain.co.ke S3ecreat BAD [ALERT] Plaintext authentication not allowed without SSL/TLS, but your client did it anyway. If anyone was listening, the password was exposed. NO [PRIVACYREQUIRED] Plaintext authentication disallowed on non-secure (SSL/TLS) connections. 2. When mdbox indexes are corrupted, are they automatically repaired/rebuilt or must I specify this in the configuration? How long does it take? Nov 01 12:08:04 pop3(wash(a)domain.co.ke): Error: Corrupted dbox file /var/spool/virtual/domain.co.ke/wash/mdbox/storage/m.1 (around offset=1941): Ex t refs metadata corrupted: 3861 783856 75/80/75805ed445f1b8b31508dba8d86280a37a74aec1-fabfb11f9f80654ced090000dcbe1dcb Nov 01 12:08:04 pop3(wash(a)domain.co.ke): Error: Corrupted dbox file /var/spool/virtual/domain.co.ke/wash/mdbox/storage/m.1 (around offset=1941): ui d=5 points to broken data at offset=1911 Nov 01 12:08:04 pop3(wash(a)domain.co.ke): Warning: mdbox /var/spool/virtual/ domain.co.ke/wash/mdbox/storage: rebuilding indexes When I connect using outlook, I see this on Outlook: Task 'wash(a)domain.co.ke - Receiving' reported error (0x800CCC90) : 'Your incoming (POP3) e-mail server has reported an internal error.

[Dovecot] [OT] dovecot appliance
by Johan Hendriks 29 Oct '10

29 Oct '10

Hello all. I am reading the mailinglist for a long time now, and there was a thread i believe called webgui or something. In this thread there was a company i believe german, that was working on a dovecot appliance with a web based gui to administrate a dovecot mail server. The problem is i did not save the URL of that company. Does anyone know which company make the appliance. Or does anyone knows a good webbased tool for dovecot. The reason is that in a windows environment, with only a few FreeBSD machine's , my collega's get frustrated if they can not use a mouse. They even want a mouse on there smartphone's :D I am doing the administration of the mail server, but when i am not there, it would be nice if they can do things them selves. thanks for your time. regards, Johan Hendriks

ALL other mail delivers perfectly but I dont know whats with crontab on this mail server. Thanks Jerrale G. SC Senior Admin

[Dovecot] Upgrading from 1.2.8 to 2.0.6: INBOX not selectable in Thubderbird (greyed and italic)
by Michele Bergonzoni 29 Oct '10

29 Oct '10

I recently upgraded from 1.2.8 to 2.0.6, I am using Maildir, and Thunderbird is showing the INBOX grayed out and in italics, and does not show new messages in it (it shows messages previously downloaded). This occurs when Thunderbird is restarted (if I upgrade dovecot, TB keeps working fine until I shut it down, and at next startup it greys out the inbox). All the subfolders of INBOX work fine. Accessing with horde+imp webmail works fine. I'm using TB 3.1.6 After some traffic capturing, The first difference I see in the IMAP exchange is the answer to 6 list "" "INBOX" Which for 1.2.8 is: LIST (\HasChildren) "." "INBOX" and for 2.0.6 is: LIST (\Noselect \HasChildren) "." "INBOX" Of course for the same user and same maildir. I enabled tb-extra-mailbox-sep in 2.0, but it doesn't appear to differ (I don't really think it should). Any help will be very much appreciated. My 1.2.8 config for the namespaces is: namespace private { prefix = INBOX. inbox = yes location = maildir:~/Maildir } namespace public { prefix = shared. location = maildir:/usr/local/shared list = yes subscriptions = no } And the config for 2.0.6 is the same with new syntax: namespace { type = private prefix = INBOX. inbox = yes location = maildir:~/Maildir } namespace { type = public prefix = shared. location = maildir:/usr/local/shared list = yes subscriptions = no } Regards, Michele Bergonzoni

[Dovecot] Can you POP a specific folder in Dovecot?
by Peter Reinhold 29 Oct '10

29 Oct '10

Hi all, I am in the middle of migrating from an old, Windows based mailserver, and have run into a small challenge I hope someone here can help me with. In my old setup, a user could have folders on the server, and by using his login with the mailbox appended, could pop a given folder specifically. For instance, logging in with user(a)example.com would pop INBOX, and logging in with user-folder(a)example.com would pop just that specific folder. Is it possible to do something like this in Dovecot, or is the only possible way of popping folders by using the virtual plugin?

Hello Dovecot users, There haven't been that many Pigeonhole developments lately, not even really significant bugs were reported. That is why this release is pretty small in terms of changes. However, one issue got some attention: the fact that not recompiling Pigeonhole for Dovecot v2.0.3 would result in rather interesting message delivery. Normally, Dovecot would complain about a version mismatch, but unfortunately Pigeonhole's Sieve plugin didn't record the Dovecot version it was compiled with. Starting with this release, such problems should not occur again. Changelog v0.2.1: + Incorporated distinction between original and final envelope recipient in Sieve interpreter, as recently introduced in Dovecot. + Regex extension: added support for regex keys composed from variables. - LDA Sieve plugin: added _version symbol to enable Dovecot's plugin version check. Without this check, people can forget to recompile the plugin, which can lead to unexpected effects. - LDA Sieve plugin: turned debug message about an unconfigured home directory into a proper error and added script path information. - Fixed unnecessary reporting of dummy extensions in ManageSieve SIEVE capability; the comparator-i;octet and comparator-i;ascii-numeric 'extensions' were reported explicitly. The release is available as follows: http://www.rename-it.nl/dovecot/2.0/dovecot-2.0-pigeonhole-0.2.1.tar.gz http://www.rename-it.nl/dovecot/2.0/dovecot-2.0-pigeonhole-0.2.1.tar.gz.sig Refer to http://pigeonhole.dovecot.org and the Dovecot v2.0 wiki for more information. Have fun testing this new release and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

[Dovecot] problem with virtual plugin/index files?
by Lutz Preßler 29 Oct '10

29 Oct '10

Hello, with latest 2.0.6 (601065674f74), the following virtual mailbox is not behaving correctly. I'm quite sure that the problem has not existed in some earlier 2.0.x (maybe only INBOX as mailbox then though): ~user/Maildir/virtual/.week/dovecot-virtual contains INBOX INBOX.* -INBOX.Trash inthread refs younger 604800 This works as expected for the first time. But later on, also older messages/ threads are included until I delete the virtual/.week/dovecot.index*.

[Dovecot] dsync, separator, but really - Default Namespace
by Daniel L. Miller 29 Oct '10

29 Oct '10

Just made the leap from 1.2 to 2.0.6 - and several maddening config typos I think I have a working system again! Getting closer to converting from maildir to mdbox, but first... Trying to use dsync gives me: dsync(root): Fatal: Mail locations must use the same virtual mailbox hierarchy separator (specify separator for the default namespace) Ok - I 've never configured namespaces before...time to learn. So my first attempt - is the following config the same as having no explicit namespace declaration?: # My Default Namespace namespace { type = private separator = '.' prefix =. location = /var/mail/%d/%n/Maildir inbox = yes hidden = no list = yes subscriptions = yes } -- Daniel

[Dovecot] Problem with quota and mdbox and quota warning
by Patrick Westenberg 28 Oct '10

28 Oct '10

Hi again, I just recognized that my dovecot forgets the quota for a mailbox. This is what the maildirsize looks like: 1 read mail present, 1 new/unread mail 2097152S 0 0 909936 1 and later, with 2 read mails: 2097152S 0 0 There are no errors logged. Moreover, my quota warning script doesn´t work because dovecot doesn´t recognize my specified folder. I specified /usr/local/etc/dovecot/quota-warning.sh but the log shows that dovecot looks somewhere else: Error: quota: connect(/usr/local/var/run/dovecot/quota-warning) failed: Permission denied # 2.0.1: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 2.6.26-2-amd64 x86_64 Debian 5.0.5 disable_plaintext_auth = no mail_gid = vmail mail_location = mdbox:~/mdbox mail_plugins = quota mail_uid = vmail managesieve_notify_capability = mailto managesieve_sieve_capability = comparator-i;octet comparator-i;ascii-casemap fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date namespace { inbox = yes location = prefix = INBOX. separator = . type = private } passdb { args = /usr/local/etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { quota = maildir:User quota quota_rule2 = INBOX.Trash:storage=+50M quota_warning = storage=90%% quota-warning 90 %u quota_warning2 = storage=75%% quota-warning 75 %u sieve = ~/.dovecot.sieve sieve_global_path = /usr/local/etc/dovecot/sieve/default.sieve } protocols = lmtp imap sieve service auth { unix_listener /var/spool/postfix/private/auth { mode = 0666 } } service imap-login { service_count = 1 } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0660 user = postfix } } service managesieve-login { inet_listener sieve { port = 4190 } inet_listener sieve_deprecated { port = 2000 } service_count = 1 } service quota-warning { executable = script /usr/local/etc/dovecot/quota-warning.sh user = vmail } ssl = no userdb { args = /usr/local/etc/dovecot/dovecot-sql.conf.ext driver = sql } protocol lmtp { mail_plugins = $mail_plugins sieve } protocol lda { mail_plugins = $mail_plugins sieve } protocol imap { mail_plugins = $mail_plugins imap_quota }

[Dovecot] Can quota_rule be inherited by child mailboxes?

28 Oct '10

Is there a way to make quota_rule apply to subfolders? I've got some symlinked mailboxes which I want to exclude from quotas. This would work, but is verbose: quota_rule6 = USERS.aaa:ignore quota_rule7 = USERS.bbb:ignore ... quota_rule9999 = USERS.zzz:ignore But simply writing this: quota_rule7 = USERS:ignore doesn't apply to USERS.xxx and so on. The wiki says '*' isn't supported as a wildcard and frankly I'm struggling with the source code!

[Dovecot] Per User Quotas with LDAP on Dovecot 1.x
by Camron W. Fox 28 Oct '10

28 Oct '10

Alle, We're running Dovecot V1.0.7 on RHEL5.5, using maildir. We would like to user per user quotas with an OpenLDAP (V2.3.43) backend. We have setup a default quota in /etc/dovecot.conf: quota = maildir:storage=10240:ignore=Trash And have the following userdb configs in /etc/doveconf.conf: userdb ldap { args = /etc/dovecot-ldap.conf } and the following user_attrs defined in /etc/dovecot-ldap.conf user_attrs = uidNumber=uid,gidNumber=gid,mailQuotaSize=quota=maildir:ignore=Trash:storage,mail_plugins The user's quota setting is: dn: uid=loadtest,ou=people,dc=subaru,dc=nao,dc=ac,dc=jp mailQuotaSize: 1024000 Dovecot-imap appear to recognize the quota from ldap, as the Thunderbird quota plugin reads the correct info from LDAP if the mailQuotaSize entry exists, and the default storage=10240 from doveconf.conf if there is no LDAP attr. However, deliver bounces the mails with a quota exceeded message: deliver(loadtest): Sep 28 10:46:23 Info: msgid=<20100928204620.B83876402EA(a)loa.subaru.nao.ac.jp> : save failed to INBOX: Quota exceeded deliver(loadtest): Sep 28 10:46:23 Info: msgid=<20100928204620.B83876402EA(a)loa.subaru.nao.ac.jp> : Rejected: Quota exceeded Are we misunderstanding the way quotas are supposed to work in 1.x, or are we just missing something, period?

[Dovecot] imap can't reconnect to auth-master after setuid
by Mike Abbott 27 Oct '10

27 Oct '10

With service imap { client_limit = 5, service_count = 0 }, when the auth process crashes the existing imap processes cannot reconnect to the auth-master socket because they have long ago dropped root privileges. Is the right solution to this: (1) change the perms on the auth-master socket so processes running as vmail:vmail can connect to it, or (2) change the code so that multi-client imap processes stop accepting new clients when they notice an auth bounce? If (1), the wiki should be updated to mention this. Thanks.

[Dovecot] Smart boxes
by Marcelo Salhab Brogliato 27 Oct '10

27 Oct '10

Hi, I'm using dovecot as IMAP server. I access my mails trough Mail (Mac client), iPhone and webmail. In Mail I use a smartbox that shows all my unread messages, no matter where it is. I really want this feature at my iPhone, so I'm thinking about developing a plugin that will create the smart unread box and follow these rules: - Every new mail arrived, it will create a hard link to directory .smart.unread (in case of Maildir); - Every mark as unread, it will create a hard link; - Every mark as read, it will remove the hard link; - Every mail delete, it will remove all files with same inode. This way, a smartbox with all unread messages will be available into webmail, iPhone and every IMAP client. What do you think about it? Is there a simple way? If it is a cool feature, I'll develop it and post the plugin here. Regards, Marcelo

[Dovecot] Dovecot's maildir format / is rm safe
by ian＠comtek.co.uk 26 Oct '10

26 Oct '10

Is it considered 'safe' to delete directly from a dovecot Maildir? I mean things of the form: rm Maildir/cur/1288062016.M581217P9422.alpha,S=1873,W=1900:2,S The wiki tells me 'If you wish to modify them in any way, create a new message instead and expunge the old one. ' but it doesn't mention deleted files. Specifically I'm wondering what happens with: dovecot.index dovecot.index.cache dovecot.index.log dovecot-uidlist Since (http://wiki.dovecot.org/IndexFiles) tells me these files index each message is there a chance of Dovecot breaking badly if it can't find them? Is it intelligent enough to automatically update the above files when it finds a missing message file? Would simply deleting the 4 files be appropriate? I have users with 4 gig mailboxes so I really wouldn't want to be deleting those files in a script every night if its a long winded process to regenerate them. Thanks in advance for any help, Ian

[Dovecot] post-login scripting using PHP
by Maciej Uhlig 26 Oct '10

26 Oct '10

I'd like to write post-login script using PHP. I noticed every shell post-login script ends with: exec "$@", which effectively executes dovecot's script-login. However, while I try to do the same (?) in PHP: $prog = $argv[1]; exec ("$prog"); it doesn't work. The client timeouts, dovecot (2.0.6) says "Disconnected for inactivity". May be I don't clearly see the way post-login scripting should work. Any hint to make it done? Regards, MU

[Dovecot] Exchange-replacement with SOGo
by Timo Sirainen 26 Oct '10

26 Oct '10

I thought some people here would be interested: Recently SOGo added support for OpenChange, which means Outlook can natively access it via MAPI the same way as Exchange. Everything is open source, and the great thing about SOGo is that it uses existing IMAP server for mails rather than reimplementing yet another one itself. They seem to prefer Cyrus, but apparently Dovecot should work too. For non-mail (calendar, etc) it uses SQL, but I heard it's not too difficult to replace that either if someone would prefer some NoSQL database or something. http://www.sogo.nu/ http://www.openchange.org/

[Dovecot] doveadm-expunge not expunging when ran from cron
by LEVAI Daniel 26 Oct '10

26 Oct '10

Hi! I noticed that this command ... : for USERNAME in ${USERS};do /usr/local/bin/doveadm -Dv expunge -u "${USERNAME}" mailbox sa.* SAVEDBEFORE 1d done ... does not expunge mails if ran from crontab. It shows in the Debug output what would have been done, but it doesn't really expunge those mails. This command runs daily, and every day the list of expunged mails (in the Debug output) just grows and grows, and the sa.* directories stay the same (except the new mails of course). However, if I run it from a terminal it really expunges the mails. Example output: doveadm(root): Debug: Loading modules from directory: /usr/local/lib/dovecot doveadm(root): Debug: Module loaded: /usr/local/lib/dovecot/lib10_quota_plugin.so doveadm(root): Debug: Loading modules from directory: /usr/local/lib/dovecot/doveadm doveadm(root): Debug: Skipping module doveadm_expire_plugin, because dlopen() failed: Cannot load specified object (this is usually intentional, so just ignore this message) doveadm(root): Debug: Module loaded: /usr/local/lib/dovecot/doveadm/lib10_doveadm_quota_plugin.so doveadm("${USERNAME}"): Debug: expunge: box=sa.spam uid=6657 doveadm("${USERNAME}"): Debug: expunge: box=sa.spam uid=6658 doveadm("${USERNAME}"): Debug: expunge: box=sa.spam uid=6659 doveadm("${USERNAME}"): Debug: expunge: box=sa.spam uid=6660 doveadm("${USERNAME}"): Debug: expunge: box=sa.spam uid=6661 doveadm("${USERNAME}"): Debug: expunge: box=sa.spam uid=6662 [...] If ran from cron, then the same uids show up every day, and new ones gets added (as new mails gets copied into those directories). Is there something fishy going on in doveadm-expunge if it has no controlling terminal?

[Dovecot] 2.0.2 : crashes with LDA
by Jakob Curdes 26 Oct '10

26 Oct '10

Hello, I just migrated to 2.0.2 and see some <xx(a)localhost.redirectme.net> (expanded from<xx@localhost>): Command died with signal 6: "/usr/local/libexec/dovecot/dovecot-lda -c /etc/dovecot2.conf". Command output: doveconf: Panic: file settings-parser.c: line 1838 (settings_copy_deflist_unique): assertion failed: (dest_count == ccount) doveconf: Error: Raw backtrace: /usr/local/lib/dovecot/libdovecot.so.0 [0x9395c0] -> /usr/local/lib/dovecot/libdovecot.so.0(default_fatal_handler+0x45) [0x9396b5] -> /usr/local/lib/dovecot/libdovecot.so.0 [0x938c78] -> /usr/local/lib/dovecot/libdovecot.so.0 [0x9183c7] -> /usr/local/lib/dovecot/libdovecot.so.0 [0x9182de] -> /usr/local/lib/dovecot/libdovecot.so.0(settings_parser_apply_changes+0x6f) [0x91849f] -> /usr/local/bin/doveconf(config_filter_parsers_get+0x25f) [0x804e8af] -> /usr/local/bin/doveconf(config_parse_file+0x6a8) [0x80502f8] -> /usr/local/bin/doveconf(main+0x21f) [0x804c43f] -> /lib/i686/nosegneg/libc.so.6(__libc_start_main+0xdc) [0x5c8e9c] -> /usr/local/bin/doveconf [0x804b291] This does not happen always; most mails get delivered normally through the LDA. A command line call of doveconf yields no problems. Any hints? Best regards, Jakob Curdes

[Dovecot] merge mdboxes
by Tobias Daucher 26 Oct '10

26 Oct '10

Hi there, after migration we have a very big problem... there are two mailboxes in /var/mail/username/mailboxes/ /var/mail/username/mailboxes/inbox /var/mail/username/mailboxes/inbox2 i DO have to merge these boxes, but i found no tools for this step. is there any way with doveadm oder dsync to move alle messages from mdbox inbox2 into mdbox inbox? i hope you all can tell me a way to do this - its a very very big problem at the moment. By the way - logging in via imap with thunderbird und move them on that way is not my favorite solution cause i have to do this for hundreds of users... i hope you can help me! thanks a lot!

I don't really know if there's much to do about this. I guess it could wait a second or so before disconnecting client to avoid it reconnecting back too fast.. > The client wasn't reconnecting as far as I can tell. It looked to me like the server process wedged after this error - we only got the error message logged once. The problem is that after it occurred no new clients could complete connections, but existing clients worked ok. Incoming connections were accepted, but then nothing would happen. As far as I can tell the parent would fork new child processes but they couldn't complete initialisation. Mail clients simply complained of a timeout during connection. This was affecting all users. With regard to error disconnections - yes a delay is a good idea.

[Dovecot] delivering mail to public mbox with permission 660?
by RParr 26 Oct '10

26 Oct '10

I am migrating a couple old RH servers running sendmail and UW-IMAP to a new Ubuntu 10.04 servers running Postfix and Dovecot. I have everything working reasonably well except that the permissions of newly created mbox mail folders is always 600. I have reviewed the archives, google, and double checked everything is as suggested in the Dovecot Wiki / SharedMailboxes / Permissions. I am running Ubuntu 10.04 packages postfix 2.7.0-1, dovecot-common, dovecot-imapd, dovecot-pop3d, and dovecot-postfix (all version 1.2.9-1ubuntu6.1). I plan to install amavisd-new, et.al. for spam filtering and anti-virus but have held off until I get Postfix and Dovecot working 100%. I have configured Postfix and Dovecot to use mbox mailboxes. I chose mbox becaus I have a LOT of shared mbox folders to migrate and decided it best to first migrate to Postfix/Dovecot mbox and later worry about migrating to maildir (as suggested on the Dovecot wiki mailbox format page). I have configured private (also as default) and public namespaces with the public mailboxes stored in /var/mail/public. /var/mail/public has rwxrws--- and is group tarts (the shared "company" group for this server). Initially I had procmail configured via the mailbox_command. Initial test mail sent to user tarts triggered creation of /var/mail/tarts with 660 permissions as expected. I then changed the configuration to use deliver via the mailbox_command. I did this because procmail appears to be unmaintained and to benefit from deliver's support for indexing at time of delivery and seive. I then added user testuser with primary group testuser and supplemental group tarts. I made sure testuser's home directory and mail sub dir had rwxrws--- permissions. I sent test mail to user testuser and had both user tarts and user testuser create some subfolders in public (via Thunderbird accounts) THE PROBLEM is that mbox folders that hold messages are created with permssion 600. My understanding, from the Dovecot wiki and other docs/postings is that the folders should be 660 given the /var/mail permssions of rwxrwsrwt and ~/mail permssions of rwxrws--- MY QUESTION is how do I correct the configuration and/or directory permissions so that mbox folders and .imap indices (especially public/ ones) are created with 660 permissions thus allowing users who belong to a common group (eg tarts) to access the public mailboxes? It appears all Dovecot configuration options to establish directory/box perms or mask, such as umask, have been deprectated and no longer work. The primary option appears to be using the permissions yet that is not working for me here. ----------------------------------- /home/: drwxrws--- 4 tarts tarts 4096 2010-10-19 13:59 tarts/ /home/tarts: drwxrws--- 4 tarts tarts 4096 2010-10-19 13:50 mail/ ----------------------------------- /d/home/: drwxrws--- 4 testuser testuser 4096 2010-10-19 13:59 testuser/ /d/home/testuser: drwxrws--- 4 testuser testuser 4096 2010-10-19 13:59 mail/ /d/home/testuser/mail: total 20 drwxrws--- 4 testuser testuser 4096 2010-10-19 13:59 ./ drwxrws--- 3 testuser testuser 4096 2010-10-19 13:44 ../ drwxrws--- 3 testuser testuser 4096 2010-10-19 13:45 .imap/ -rw-rw---- 1 testuser testuser 36 2010-10-19 13:59 .subscriptions -rw------- 1 testuser testuser 0 2010-10-19 13:50 Trash drwxrws--- 2 testuser testuser 4096 2010-10-19 13:54 test1/ -rw------- 1 testuser testuser 0 2010-10-19 13:54 test2 /d/home/testuser/mail/.imap: total 12 drwxrws--- 3 testuser testuser 4096 2010-10-19 13:45 ./ drwxrws--- 4 testuser testuser 4096 2010-10-19 13:59 ../ drwx--S--- 2 testuser testuser 4096 2010-10-19 13:50 INBOX/ /d/home/testuser/mail/.imap/INBOX: total 24 drwx--S--- 2 testuser testuser 4096 2010-10-19 13:50 ./ drwxrws--- 3 testuser testuser 4096 2010-10-19 13:45 ../ -rw------- 1 testuser testuser 16384 2010-10-19 14:00 dovecot.index.cache -rw------- 1 testuser testuser 864 2010-10-19 14:00 dovecot.index.log /d/home/testuser/mail/test1: total 8 drwxrws--- 2 testuser testuser 4096 2010-10-19 13:54 ./ drwxrws--- 4 testuser testuser 4096 2010-10-19 13:59 ../ -rw------- 1 testuser testuser 0 2010-10-19 13:54 sub1 ----------------------------------- /var: drwsrwsrwt 3 root mail 4096 2010-10-18 10:23 mail/ /var/mail: total 896 drwsrwsrwt 3 root mail 4096 2010-10-19 13:51 ./ drwxr-xr-x 16 root root 4096 2010-03-05 13:57 ../ -rw-rw---- 1 nobody mail 1386 2010-10-12 16:54 nobody drwsrws--- 5 root tarts 4096 2010-10-19 13:51 public/ -rw-rw---- 1 tarts mail 894107 2010-10-19 08:59 tarts -rw------- 1 testuser mail 632 2010-10-19 13:51 testuser /var/mail/public: total 24 drwsrws--- 5 root tarts 4096 2010-10-19 13:51 ./ drwsrwsrwt 3 root mail 4096 2010-10-19 13:51 ../ drwxrws--- 3 tarts tarts 4096 2010-10-19 13:51 .imap/ drwxrws--- 3 tarts tarts 4096 2010-10-16 15:02 test1/ drwxrws--- 2 tarts tarts 4096 2010-10-16 15:01 test2/ -rw------- 1 testuser tarts 633 2010-10-19 13:51 test3 /var/mail/public/.imap: total 12 drwxrws--- 3 tarts tarts 4096 2010-10-19 13:51 ./ drwsrws--- 5 root tarts 4096 2010-10-19 13:51 ../ drwx--S--- 2 testuser tarts 4096 2010-10-19 13:51 test3/ /var/mail/public/.imap/test3: total 28 drwx--S--- 2 testuser tarts 4096 2010-10-19 13:51 ./ drwxrws--- 3 tarts tarts 4096 2010-10-19 13:51 ../ -rw------- 1 testuser tarts 16384 2010-10-19 13:51 dovecot.index.cache -rw------- 1 testuser tarts 628 2010-10-19 13:51 dovecot.index.log /var/mail/public/test1: total 16 drwxrws--- 3 tarts tarts 4096 2010-10-16 15:02 ./ drwsrws--- 5 root tarts 4096 2010-10-19 13:51 ../ drwxrws--- 3 tarts tarts 4096 2010-10-16 15:02 .imap/ -rw------- 1 tarts tarts 614 2010-10-16 15:02 sub1 -rw------- 1 tarts tarts 0 2010-10-16 15:01 sub2 /var/mail/public/test1/.imap: total 12 drwxrws--- 3 tarts tarts 4096 2010-10-16 15:02 ./ drwxrws--- 3 tarts tarts 4096 2010-10-16 15:02 ../ drwx--S--- 2 tarts tarts 4096 2010-10-16 15:02 sub1/ /var/mail/public/test1/.imap/sub1: total 12 drwx--S--- 2 tarts tarts 4096 2010-10-16 15:02 ./ drwxrws--- 3 tarts tarts 4096 2010-10-16 15:02 ../ -rw------- 1 tarts tarts 408 2010-10-16 15:02 dovecot.index.log /var/mail/public/test2: total 8 drwxrws--- 2 tarts tarts 4096 2010-10-16 15:01 ./ drwsrws--- 5 root tarts 4096 2010-10-19 13:51 ../ Any help would be greatly appreciated.

26 Oct '10

http://dovecot.org/releases/2.0/dovecot-2.0.6.tar.gz http://dovecot.org/releases/2.0/dovecot-2.0.6.tar.gz.sig * Pre-login CAPABILITY includes IDLE again. Mainly to make Blackberry servers happy. * auth: auth_cache_negative_ttl default was 0 in earlier v2.0.x, but it was supposed to be 1 hour as in v1.x. Changed it back to 1h. If you want it disabled, make sure doveconf shows it as 0. + dbox: Added support for saving mail attachments to external files, with also support for single instance storage. This feature hasn't had much testing yet, so be careful with it. + doveadm: Added import command for importing mails from other storages. + Reduced NFS I/O operations for index file accesses + dbox, Maildir: When copying messages, copy also already cached fields from dovecot.index.cache + mdbox: Added mdbox_preallocate_space setting (Linux+ext3/XFS only) - Maildir: LDA/LMTP assert-crashed sometimes when saving a mail. - Fixed leaking fds when writing to dovecot.mailbox.log. - Fixed rare dovecot.index.cache corruption - IMAP: SEARCH YOUNGER/OLDER wasn't working correctly

Because the parent directory was rwxr-xr-x root.root The problem is that for some reason dovecot then wedged and a lot of other stuff piled up behind it, causing people to complain their mail wasn't coming through. Load average climbed to over 100. Creating the user directories freed things up...

I have been, but I've seen no similar reports and it may still be in 2.0.6. I will update to that version during a planned maintenance window tomorrow.

compatible ) or pop3_uidl_format = %g ( better with virtual ) pop3_reuse_xuidl = ? what ist the most compatible/konservative setting with maildir on a cluster filesystem pop3_save_uidl = ? what ist

[Dovecot] Auto delete older messages in SPAM folder
by Thiago Henrique 25 Oct '10

25 Oct '10

Hello, I use Cyrus in my mailservers and I intend to migrate it to Dovecot. Cyrus has a setting that purge the emails from a mailbox under a pre-defined criteria. For example: EVENTS { ... # At 12:01 delete messages older than 60 days in SPAM folder deletespam cmd="ipurge -d 60 -f user/*/SPAM" at=1201 } Is there in Dovecot any setting like this ? Thank you. -- []'s Thiago Henrique Network Administration Digirati Networks K8 Networks

[Dovecot] Problems converting to maildir with dsync in 2.0.6
by Nicholas Riley 25 Oct '10

25 Oct '10

I'm trying to convert from an old Dovecot (1.0.15) and mbox to a new Dovecot and maildir. I'm running into several problems with dsync which are causing my mboxes not to convert. If I use LAYOUT=fs (as I'd prefer) I get an error because I have a mailbox called "subscriptions", and none of my messages convert. Is there a way to get dovecot to put its own metadata in dotfiles instead? (I guess I can rename my mailbox too :-) % dsync mirror mbox:~/Mail dsync(nriley): Error: read() failed with subscription file /home/nriley/Maildir/subscriptions: Is a directory dsync(nriley): Error: Can't update subscription +/INBOX: Internal error occurred. Refer to server log for more information. [2010-10-21 20:17:55] [...] Also, what "server log" is it referring to above? So I tried without LAYOUT=fs, and dsync successfully converts some mailboxes, then crashes: % dsync mirror mbox:~/Mail dsync(nriley): Error: Maildir: 6ef533cd4cdb1fd454b0226bfc851bb3:2, changed UID 1846529 -> 1846531 dsync(nriley): Panic: file maildir-save.c: line 892 (maildir_save_sync_uidlist): assertion failed: (ret > 0) dsync(nriley): Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0 [0xb7ea21f1] -> /usr/lib/dovecot/libdovecot.so.0(default_fatal_handler+0x47) [0xb7ea2317] -> /usr/lib/dovecot/libdovecot.so.0(i_error+0) [0xb7ea2544] -> /usr/lib/dovecot/libdovecot-storage.so.0(maildir_transaction_save_commit_ pre+0x858) [0xb7f2ab58] -> /usr/lib/dovecot/libdovecot-storage.so.0 [0xb7f2501f] -> /usr/lib/dovecot/libdovecot-storage.so.0(mail_index_transaction_commit_fu ll+0x85) [0xb7f67eb5] -> /usr/lib/dovecot/libdovecot-storage.so.0(index_transaction_commit+0x94) [0xb7f24c14] -> /usr/lib/dovecot/libdovecot-storage.so.0(mailbox_transaction_commit_get_c hanges+0x42) [0xb7efeaa2] -> /usr/bin/dsync [0x8056ed2] -> /usr/bin/dsync [0x80570f0] -> /usr/bin/dsync(dsync_worker_select_mailbox+0x2e) [0x8055b2e] -> /usr/bin/dsync [0x80507e6] -> /usr/bin/dsync [0x8050a3b] -> /usr/bin/dsync(dsync_brain_msg_sync_new_msgs+0x12) [0x8050c12] -> /usr/bin/dsync(dsync_brain_msg_sync_more+0x2e1) [0x8050261] -> /usr/bin/dsync(dsync_brain_sync+0x309) [0x804e949] -> /usr/bin/dsync [0x804f953] -> /usr/bin/dsync(dsync_brain_sync+0x72e) [0x804ed6e] -> /usr/bin/dsync [0x804f7d0] -> /usr/bin/dsync(dsync_brain_sync+0x55d) [0x804eb9d] -> /usr/bin/dsync(dsync_brain_sync_all+0x18) [0x804f668] -> /usr/bin/dsync(main+0x5a1) [0x804da51] -> /lib/libc.so.6(__libc_start_main+0xe5) [0xb7d29455] -> /usr/bin/dsync [0x804d2e1] [1] 30528 abort dsync mirror mbox:~/Mail I tried running it in GDB but that crashed GDB, so hopefully the above info is OK... % gdb --args dsync mirror mbox:~/Mail (gdb) run Starting program: /usr/bin/dsync mirror mbox:\~/Mail [Thread debugging using libthread_db enabled] [New process 30652] Executing new program: /usr/bin/doveconf warning: Cannot initialize thread debugging library: generic error warning: Cannot initialize thread debugging library: generic error warning: Cannot initialize thread debugging library: generic error warning: Cannot initialize thread debugging library: generic error [New process 30652] [Thread debugging using libthread_db enabled] [1] 30651 segmentation fault gdb -q --args dsync mirror mbox:~/Mail I'm using the Debian packages from rename-it.nl.

[Dovecot] Recommendation for OCFS2 filesystem type
by Andre Nathan 25 Oct '10

25 Oct '10

Hello When creating an OCFS2 filesystem, one can specify a "filesystem type" option: -T filesystem-type Specify how the filesystem is going to be used, so that mkfs.ocfs2 can chose optimal filesystem parameters for that use. The supported filesystem types are: mail Appropriate for file systems which will have many meta data updates. Creates a larger journal. datafiles Appropriate for file systems which will host a rela‐ tively small number of very large files. A small journal is selected. Cluster size will be at least 128K. Considering I'm using a separate partition for the dovecot indices, and that I'm using mdbox, would it be more appropriate to use 'datafiles' for the mail location partition and 'mail' just for the indices? Or would 'mail' be appropriate for both even with the larger files created by mdbox? Thanks, Andre

[Dovecot] problem with subscriptions=no and changed separator ?
by Lutz Preßler 25 Oct '10

25 Oct '10

Hello, Dovecot 2.0.5+ (Debian "automatic package" 2.0.5-0~auto+5). If I use the following namespace definitions namespace personal { inbox = yes location = maildir:~/Maildir separator = ^ prefix = type = private } namespace others { type = shared separator = ^ prefix = shared^%%u^ location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u subscriptions = no list = children } namespace virtual { location = virtual:~/Maildir/virtual:LAYOUT=maildir++ separator = ^ prefix = virtual^ type = private } (virtual should not matter, but I have not tested without.) I have problems with subscriptions for the shared mailboxes: SUBSCRIBE ^shared^user^box leads to entry shared^user^box in ~/Maildir/subscriptions file. All subscriptions for folders in personal namespace use the "layout" separator (".") thought. LSUB "" "*" does not show the just subscribed folder, but it does after I manually change the entry to read shared.user.box Bug?

I can not see the subfolders of the shared inbox. This is not very useful if the user which shares his inbox, has sieve rules active that stores e-mail directly into subfolders.

[Dovecot] Manual login to SSL-protected port?
by Ron Leach 25 Oct '10

25 Oct '10

List, good afternoon, Dovecot and mail clients work fine. Several recent postings mention trying telnet to check this or that and, since I was considering using a spreadsheet plug-in to analyse some mail statistics by directly connecting to the server, I thought I'd try to test what the command sequence was that I might be able to use, and what message data was available (headers etc). We use only SSL-protected ports. Is it possible to manually login to dovecot when dovecot uses SSL-protected imap ports? I've tried telnet and the telnet localhost 993 login user pass resulted in connection closure, as I (think I) would expect because telnet doesn't use SSL (does it?). I checked man telnet and it described authentication options but when I tried telnet localhost 993 auth enable ? to check what auth protocols it allows, the connection closed. I tried SSH but it just 'hung' - presumably SSH expects an SSH server at the other end, not dovecot. Is it possible to manually login to a dovecot SSL imap port? regards, Ron

[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.

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] Correct permissions for base_dir??

[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.

[Dovecot] bug with null pointer

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

You can compile Dovecot from the official sources (apply the patch before), download/install Dovecot from Mercurial (hg.dovecot.org) or open a bugreport for the package maintainer so that the bug can be fixed for your distribution. -- Daniel

[Dovecot] Director and CRAM-MD5
by Martin Spuetz 20 Oct '10

20 Oct '10

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. CRAM-MD5 auth is working fine if I connect directly to the backends, but the director only supports AUTH=PLAIN because of the static passdb. director config: > passdb { > driver = static > args = nopassword=y proxy=y > } > > director_servers = director1 director2 > director_mail_servers = backend1 backend2 backend config: > passdb { > driver = vpopmail > args = > } > > userdb { > driver = vpopmail > } It seems that the director is only working, if I use the static passdb?! How can I use the director with other passdb drivers than the static one? Greetings, Martin

[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

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] 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.

Hello, I've some trouble with my kmail (Version 1.13.5 / KDE 4.5.1, Kubuntu 10.04 and a dovecot-imap-server on debian etch (dovecot 1.0.rc15-2etch5). 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 ?

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?????

[Dovecot] Samba4 Active Directory and Doveadm
by Trever L. Adams 15 Oct '10

When executing: doveadm search -A mailbox INBOX from SOMEBODY I am getting: doveadm(root): Error: user root: Invalid settings in userdb: userdb returned 0 as uid doveadm(root): Error: User lookup failed: Invalid user settings. Refer to server log for more information. doveadm(bin): Error: user bin: Couldn't drop privileges: Mail access for users with UID 1 not permitted (see first_valid_uid in config file). doveadm(bin): Error: User init failed doveadm: Error: Failed to iterate through some users hosts =FQDN base = dc=example,dc=com ldap_version = 3 user_attrs = =homeDirectory=/home/vmail/%d/%n, =mail=maildir:/home/vmail/%d/%n, uid=vmail, gid=vmail user_filter = (&(objectClass=person)(|(mail=%u)(sAMAccountName=%u)(userPrinicipalName=%u))) # For using doveadm -A: iterate_attrs = uid=samaccountname iterate_filter = (objectClass=person) I can receive email and login just fine. 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. Thank you for any help, Trever -- "Virtue does not always demand a heavy sacrifice -- only the willingness to make it when necessary." -- Frederick Dunn

[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
by Andre 15 Oct '10

15 Oct '10

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? TIA Andre

[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) {

[Dovecot] lazy_expunge and moving messages
by Lutz Preßler 14 Oct '10

14 Oct '10

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
by dss 14 Oct '10

14 Oct '10

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.

Some of our users need to use the same Mailbox with all folders: Inbox (with subfolders), Outbox, Send and Deleted, (some users need in full righs, some - readonly) so I choosed Symlinking mailboxes and tried to use dovecot-acl file. cat dovecot-acl: user=t1 lrwsti user=operolegs lrwsti user=operantona lrwsti user=operdss lr User operdss have lrwsti rights in this shared mailbox unstead of lr! But if I comment out other users in the dovecot-acl: #user=t1 lrwsti #user=operolegs lrwsti #user=operantona lrwsti user=operdss lr User operdss have lr rights. Whats wrong? It seems, that dovecot-acl is working only for one user and for one line in config. How can I fix it? === Here is my configs. imap:/usr/local/dovecot# /usr/local/dovecot/sbin/dovecot -n # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.26-2-686 i686 Debian 5.0.6 log_path: /var/log/dovecot.log log_timestamp: %Y-%m-%d %H:%M:%S disable_plaintext_auth: no login_dir: /usr/local/dovecot-1.2.15/var/run/dovecot/login login_executable: /usr/local/dovecot-1.2.15/libexec/dovecot/imap-login mail_privileged_group: mail mail_plugins: acl imap_acl auth default: debug: yes passdb: driver: pam userdb: driver: passwd ---- imap:~# ls -l /home/t1/Maildir lrwxrwxrwx 1 root root 21 2010-09-22 16:03 /home/t1/Maildir -> /var/mail/720/Maildir imap:~# ls -l /home/operolegs/Maildir lrwxrwxrwx 1 root root 21 2010-09-23 16:00 /home/operolegs/Maildir -> /var/mail/720/Maildir imap:~# ls -l /home/operantona/Maildir lrwxrwxrwx 1 root root 21 2010-09-23 16:00 /home/operantona/Maildir -> /var/mail/720/Maildir imap:~# ls -l /home/operdss/Maildir lrwxrwxrwx 1 root root 16 2010-09-28 16:32 /home/operdss/Maildir -> /home/t1/Maildir --- imap:/home/t1/Maildir# ls -l total 112 drwxrws--- 2 t1 mshare 4096 2010-09-27 10:46 cur -rw-rw---- 1 t1 mshare 99 2010-09-29 15:56 dovecot-acl -rw-rw---- 1 operdss mshare 312 2010-09-29 16:43 dovecot-acl-list -rw-rw---- 1 operolegs mshare 1144 2010-09-24 12:16 dovecot.index -rw-rw---- 1 t1 mshare 41984 2010-09-28 16:39 dovecot.index.cache -rw-rw---- 1 t1 mshare 25068 2010-09-28 16:38 dovecot.index.log -rw-rw---- 1 operantona mshare 17 2010-09-23 16:41 dovecot-keywords -rw-rw---- 1 operantona mshare 1941 2010-09-27 10:46 dovecot-uidlist -rw-rw---- 1 t1 mshare 8 2010-09-29 16:43 dovecot-uidvalidity -rw-rw---- 1 t1 mshare 0 2010-09-22 10:54 dovecot-uidvalidity.4c99a82f drwxrws--- 2 t1 mshare 4096 2010-09-27 10:46 new -rw-rw---- 1 operdss mshare 327 2010-09-29 16:43 subscriptions drwxrws--- 2 t1 mshare 4096 2010-09-27 10:46 tmp ----- dovecot packages - dovecot-1.2.15 --- Linux: Debian Lenny up2date
