[Dovecot] Dsync didn't updates automatically
by Breno Moreira 08 Jan '13

08 Jan '13

Hi, I'm trying to use the Dsync cluster feature in a simple setup, without director, but I'm having some troubles. First of all, I want to know if this functionality syncs the mailbox when the user receive a mail or only when the dovecot starts? Reading the Dovecot mailing list and the design description for a dsync-replicated Dovecot cluster, I understood that it should sync every time a new mail arrives, but it isn't happening in my system. So, can I do this update automatically? If yes, why is it not working properly? Maybe is my configuration files or maybe I'm confusing the capability of this feature. I'm using Dovecot 2.1.7 included in the Debian Wheezy, with virtual users in a MySQL database, Moreover, I have the following configuration: mail_plugins = $mail_plugins notify replication service aggregator { # give enough permissions for mail processes fifo_listener replication-notify-fifo { user = vmail #mode = 0666 } unix_listener replication-notify { user = vmail #mode = 0666 } } service replicator { # start replication at startup process_min_avail = 1 } plugin { # host1 replicates to host2 #mail_replica = remote:vmail at 10.127.0.2 # host2 replicates to host1 mail_replica = remote:vmail@10.127.0.5 } dsync_remote_cmd = ssh -l vmail %{host} doveadm dsync-server -u%u -l%{lock_timeout} -n%{namespace} service doveadm { # if you're using a single virtual user, set this to # start ssh as vmail (not root) user = vmail } service config { unix_listener config { user = vmail } } The vmail user has rsa id's in both servers, so it can do ssh connections without asking for password. I appreciate your help. Best Regards, -- --------------------------------------------------------------------- Breno Moreira "I have no idols. I admire work, dedication and competence." Ayrton Senna

Hi, I'm unable to get past the subject error trying to setup dovecot 2.1.10 on FreeBSD 6.4: right after login the server closes the connection (testing with telnet) I've tried manualy chown()ing auth-master to 666, so permission issues should be ruled out. I'm attaching logs, config and excerpt of ktrace -id. I've built a version with debug symbols, but I don't seem to hit a breakpoint in net_connect_unix on lib/network.c What can I look at? tks -- pica

[Dovecot] Access to deleted mails in mdbox storage
by Wolfgang.Friebel＠desy.de 08 Jan '13

08 Jan '13

Hi Timo, we are currently running dovecot 2.1.10 using mdbox storage. Sometimes we get requests from users to restore accidentally deleted mails. If the mails got deleted before a backup was made, such mails could of course not be restored from backup. One option to help users in this respect would be to use the lazy expunge plugin. On the other hand I have seen, that the deleted mails stay intact in the mdbox storage until a doveadm purge has been performed. Therefore without using the plugin it is in principle possible to get access to any deleted mails. As in our case the expunge runs once a week while the backup is done daily we can basically recover all mails ever received. My question: doveadm has currently no command similar to doveadm search or fetch to get to deleted mails. Would it be useful to have such a command? As a proof of concept I wrote a little script to mimic the doveadm fetch as closely as possible given the limited amount of information in the mdbox/storage/m.* files and could indeed get access to deleted mails. Do you regard such a procedure (within doveadm) useful or would you recommend nevertheless using the lazy expunge plugin? I am aware of the fact that this is a solution for mdbox storage only. -- Wolfgang Friebel Deutsches Elektronen-Synchrotron DESY Phone/Fax: +49 33762 77372/216 Platanenallee 6 Mail: Wolfgang.Friebel AT desy.de D-15738 Zeuthen Germany

[Dovecot] 2 node dovecot
by Lazy 08 Jan '13

08 Jan '13

Hi, We run dovecot 2.1 on 2 nodes with shared nfs storage. Index files are kept on local disk. Second node is usually used only for email snapshots access. If primary node fails it is configured to take place of the primary imap server. Snapshots are additional namespaces with mail from various points in time. We need a way to easly copy multiple messages from snapshots to current mailboxes. It would be best to make current mailbox available as another namespace so one would simply copy messages from one folder to another. Is it safe ? There will be times when given user is writing to the same nfs based Maildir mailbox from 2 nodes both of them having separate index files. What will happen if already present message gets copied back from the snapshot ? Regards, Michał Grzędzicki

[Dovecot] Director and forwarding LDAP user as Master user
by Alexandr Sabitov 08 Jan '13

08 Jan '13

Hello guys, Would you be able to help me with this little issue. I bet someone has the same config so if you can copy-paste it I will very appreciate it. So main idea is to enable Dovecot director to authenticate a LDAP user with plain or encrypted password and send the user to back-end Dovecot server after the authentication. According to Wiki it is only possible if we use the master user to communicate to the back-end server. On the back-end Dovecot server it is working fine, I can log in as normal user/user_password or as user*masteruser/master_password. The back-end config is: auth_master_user_separator = * passdb { driver = passwd-file args = /usr/local/dovecot/etc/dovecot/passwd.masterusers master = yes pass = yes } passdb { driver = ldap args = /usr/local/dovecot/etc/dovecot/dovecot-ldap.conf.ext } userdb { driver = ldap args = /usr/local/dovecot/etc/dovecot/dovecot-ldap.conf.ext } Now front-end: how to get director forward the user to the back-end after authentication on the director? With my director config the user stays on the director all the time: passdb { driver = static args = proxy=y master=masteruser pass=master_password destuser=%u*masteruser } passdb { driver = ldap args = /usr/local/dovecot/etc/dovecot/dovecot-ldap.conf.ext } userdb { driver = ldap args = /usr/local/dovecot/etc/dovecot/dovecot-ldap.conf.ext } The only way to forward the user is to setup nopassword=y in args of static passdb but in that case the user will be authenticated on the backend but not on the director... What do I missing ? Please help me Best Regards, Alexandr Sabitov

[Dovecot] BLF-CRYPT

Hi, I get "Unknown scheme: BLF-CRYPT" messages if I try to use Blowfish-encrypted passwords, even though it is supposed to be supported. I'm on 2.1.7, Debian Squeeze backports. Do you have any information whether Blowfish is supported with Debian Squeeze crypt(), or is there any other knobs I can turn on to make this algorithm available? Thanks, Kristof

My reading of all of this is that the dovecot daemon is up and running, that it's listening correctly on 143 and 993 and that I have to do something else to get authorisation even to start the IMAP dialogue with the server. I would like to get it working and locked to SSL only but thought I should start with both unencrypted and encrypted. Can someone help me or point me to the bits of documentation or good web howto or the like that I've missed? TIA, Chris (long term Debian user but it's some years since I last ran my own mail server and I'm a total newby to imap and dovecot)

[Dovecot] dovecot as layer between postfix and thunderbird
by martin svensson 05 Jan '13

05 Jan '13

Hello, im all new to this but feel i want to have a dedicated server to handle my mails from Gmail and Hotmail Basically, i installed SMS, superb Mini Server (based on slackware), and with that default install i got: dovecot, postfix, fetchmail and sendmail. The postfix part seems to work according to a "telnet localhost 25", now i want to procede with dovecot, as i understand it, its the middle layer between (in my case) postfix and thunderbird. What i expect in the very end is a dedicated server who regulary checks and fetches mails, and lets me have all contacts info in the (already up and running) LDAP server. When i start thunderbird, i want it to go grab those mails from my local machine I am, ofcourse all over manpages, HOWTOs, guides and google, but would certainly appriciate further help and points in the right direction My apologises for any weird beginner mistakes in this post

[Dovecot] doveadm backup issue with ACL plugin enabled
by Thomas Leuxner 05 Jan '13

Hi, when trying to backup mailboxes I noticed some hiccups when the ACL plugin is enabled. It works fine with ACL disabled: $ doveadm -o plugin/quota= backup -u tlx(a)leuxner.net mdbox:/home/backups/tlx/mdbox However, enabled (and w/ a mailbox actually using ACLs) the following error occurs: $ doveadm -o plugin/quota= backup -u tlx(a)leuxner.net mdbox:/home/backups/tlx/mdbox dsync(tlx(a)leuxner.net): Error: Couldn't update mailbox <name> metadata: Permission denied I tried to override the ACL plugin via '-o' to no avail, but I may be using the wrong syntax there.

[Dovecot] Non-standard fields?
by Attila Nagy 04 Jan '13

04 Jan '13

Hi, Non-standard fields are mentioned here: http://wiki2.dovecot.org/MailboxFormat/Maildir and they are stated as currently not used. Questions: - am I right that if they will be used, they will be key=value pairs, like fields in the base filename? Like: 1035478339.27041_118.foo.org,S=1000,W=1030:2,S,X=12,A=something - or are they supposed to be flags, like: 1035478339.27041_118.foo.org,S=1000,W=1030:2,S,ABCD - are there any plans to utilize these? Thanks,

[Dovecot] Dovecot Virtual Users with Sendmail
by DormitionSkete＠hotmail.com 04 Jan '13

04 Jan '13

I'm trying to get Dovecot working with Virtual Users and Sendmail on OpenIndiana 151a7. OpenIndiana is the Open Source continuation of OpenSolaris after Oracle tried to kill it off a couple of years ago shortly after acquiring Sun Microsystems. I'm not sure if this is so much a Dovecot problem, as much of a Sendmail problem. I thought this would probably be a better list to start with, though. If not, please let me know. I initially used this Dovecot wiki page to approach this: Simple Virtual User Installation http://wiki2.dovecot.org/HowTo/SimpleVirtualInstall I had to make few minor changes, but I don't think anything significant to the problem I'm having. I can log into SquirrelMail with both virtual users, and with system users. I can send mail to system users from both virtual and system users. I can see the mail that I sent in the Sent Messages folder for both types of users. I just can't send mail to virtual users. When I try to, I get the following message: ERROR: Message not sent. Server replied: Requested action not taken: mailbox unavailable 550 5.1.1 <dswebstore@localhost>... User unknown My configuration info is as follows: systemuser@openindiana:~# /usr/local/sbin/dovecot --version 2.1.12 systemuser@openindiana:~# /usr/local/sbin/dovecot -n # 2.1.12: /usr/local/etc/dovecot/dovecot.conf # OS: SunOS 5.11 i86pc auth_verbose = yes base_dir = /var/run/dovecot/ disable_plaintext_auth = no first_valid_uid = 101 info_log_path = /var/log/dovecot-info.log log_path = /var/log/dovecot.log mail_location = mbox:/home/vmail/%u/mail:INBOX=/var/mail/%u passdb { args = /usr/local/etc/dovecot/passwd driver = passwd-file } pop3_uidl_format = %g protocols = imap pop3 service auth { unix_listener auth-userdb { group = vmail mode = 0600 user = vmail } } ssl = no userdb { args = uid=vmail gid=vmail home=/home/vmail/%u driver = static } protocol lda { postmaster_address = systemuser@localhost } --- My dovecot password file looks something like this, though changed for obvious security reasons: systemuser:{PLAIN} systemuserPASS virtualuser1:{PLAIN}virtualuser1PASS virtualuser2:{PLAIN}virtualuser2PASS --- I read on this page that I needed to put the following in my sendmail dovecot.m4 file: Dovecot LDA with Sendmail http://wiki2.dovecot.org/LDA/Sendmail So this is my dovecot.m4 file, which shows up in my sendmail.cf file after recompiling my sendmail.mc file. ######################*****############## ### DOVECOT Mailer specification ### ##################*****################## Mdovecot, P=/usr/local/libexec/dovecot/dovecot-lda, F=DFMPhnu9, S=EnvFromSMTP/HdrFromSMTP, R=EnvToSMTP/HdrFromSMTP, T=DNS/RFC822/X-Unix, A=/usr/local/libexec/dovecot/dovecot-lda -d $u --- Finally, this is my sendmail.mc file: divert(-1) # # Copyright (c) 1983 Eric P.

[Dovecot] clucene-config.h location
by Dimitri 04 Jan '13

04 Jan '13

By deafult, CLucene installs the clucene-config.h header to /usr/lib/CLucene, but fts-lucene tries to include it from /usr/include/CLucene and fails. Here is how it is fixed in Fedora, for instance: sed -i '/DEFAULT_INCLUDES *=/s|$| '"$(pkg-config --cflags libclucene-core)|" src/plugins/fts-lucene/Makefile.in Indeed, Lucene's pkgconfig file reflects the fact that some headers reside in /usr/lib/CLucene. It would be great if Dovecot used pkgconfig for CLucene. Thanks, Dimitri Mageia Linux packager

[Dovecot] Can't rename mailboxes, any ideas on how to fix?
by Howard Leadmon 04 Jan '13

04 Jan '13

I am running Dovecot 2.1.12 under FreeBSD, and I use Outlook 2010 with imap to connect to my server. I know I used to be able to rename mailboxes, as I do this every year at year end, but when I went to rename some mailboxes the start of this year, blamo up popped the message "CANNOT Renaming not supported across conflicting directory permissions". Then only thing that has really been updated here, is Dovecot itself, as I know the FBSD port updates when new versions are released. Any clues on what may have caused this, or how to best correct it? --- Howard Leadmon

[Dovecot] Dovecot 1.2.7 and Roundcube LIST-EXTENDED commands
by aristidis fesarlis 04 Jan '13

04 Jan '13

Hi all, we use Dovecot 1.2.7 with Maildir, and recently we have set up the latest Roundcube webmail. Inside its config file,it is mentioned that: // By default list of subscribed folders is determined using LIST-EXTENDED // extension if available. Some servers (dovecot 1.x) returns wrong results // for shared namespaces in this case. http://trac.roundcube.net/ticket/1486225 // Enable this option to force LSUB command usage instead. I notice that it seems to work fine, though. We don't have shared namespaces. So my question is: should I change it to LSUB, or will I have problems with my Maildir subscriptions? Thanks

[Dovecot] Folder names
by James Starowitz 04 Jan '13

04 Jan '13

Running a pretty basic setup of imap +pop3 on version 2.1.10 Users are able to create folders in imap that contain "&" the folder on the backend reflects "&-" as it should, you can list folder, but then when you relog into imap then decides it can no longer subscribe to this folder due to invalid UTF characters. Essentially allowing users to lock themselves out by using a very common character in a folder name. Might one of the imap client compatibility plugins in imapd cause this quirkiness ? Should I be coming at this from another direction? Is this a bug?

[Dovecot] Kerberos/GSSAPI auth via .k5login file
by Jörg Herzinger 04 Jan '13

04 Jan '13

Hi, we are currently moving our mailserver to a new server with Dovecot, virtual users in LDAP, Passwords in Kerberos Setup. Everything works fine except for GSSAPI which seems to be a bit buggy. The thing is, that when using a .k5login [1] file it seems that SASL does not get passed the home directory specified userdb. In other words, mails for user1 (see below) are stored in /home/domain.at/user1, while the home dir defined in LDAP is /afs/domain.at/home/user1 (virtual users, so only dovecot, not the system does know about this user and home dir). If I do create a .k5login file in /home/domain.at/user1 with the content "someotheruser(a)DOMAIN.AT", then someotheruser should be able to authenticate himself as user1 via GSSAPI. However, this .k5login file is completely ignored. So it seems to me that the home is not passed on to SASL. If I do add ldap to my nsswitch (for testing only) I additionally have real system users. Now if I create a .k5login in their home defined in LDAP which now also the system knows about everything works just fine. It is still the wrong home since its the one in LDAP and not the one defined by dovecot but at least it shows that our setup is working.

[Dovecot] dovecot and avahi
by Robert Moskowitz 03 Jan '13

03 Jan '13

I am trying to figure out if I need avahi on my mail server. I see that POP3 and IMAP are services that Avahi can advertise/discover. Does Dovecot work with Avahi and how do you get POP3 and IMAP advertised? And perhaps more importantly, what clients look for mail services this way? I can't find any information on this in the Dovecot documentation ot googling. Perhaps my search fu is low this year. thank you

[Dovecot] Migration Problem UW-IMAP to Dovecot Maildir
by Michael Sloan 03 Jan '13

03 Jan '13

I've just replaced our ancient (10-year old) mail server running Sendmail/UW-IMAP on Solaris with Postfix/Dovecot 2.1.10 running on Linux on new hardware. I opted to go with virtual users and I didn't want to create system accounts and I might end up hosting another department's mail as well. We have a mix of POP3 and IMAP users, roughly 90 total. The POP3 user mailboxes migrated without a hitch, and the IMAP user mailboxes (in what looks like mbox format) migrated well for the INBOX (found in /var/mail/<username> ) but for those few who managed to create local folders and had mail files in their home directories, those mail files were ignored. Is there any clean way to manage to migrate those folders to the new server now? There were no .mailboxlist or .subscription files anywhere on the old mail server. When I was planning the migration, I tried a variety of the methods listed on the UW-IMAP and generic migration pages including dsync, uw2dovecot.pl, and several others. What appeared to work well at the time was this, although I still have the mail in users' home directories to recover/migrate: /usr/local/bin/doveadm -o imapc_user=$1 -o pop3c_user=$1 -o imapc_password=$2 -o pop3c_password=$2 backup -R -u $1(a)caps.fsu.edu imapc: with this dovecot.conf: # 2.1.10: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 3.0.13-0.27-pae i686 SUSE Linux Enterprise Server 11 (i586) ext3 auth_mechanisms = plain login disable_plaintext_auth = no imapc_features = rfc822.size imapc_host = p1.caps.fsu.edu imapc_list_prefix = INBOX listen = * mail_location = maildir:/var/vmail/%d/%n/Maildir namespace { hidden = yes list = no location = pop3c: prefix = POP3-MIGRATION-NS/ } namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = separator = . } passdb { args = /usr/local/etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { pop3_migration_mailbox = POP3-MIGRATION-NS/INBOX } pop3_uidl_format = %08Xv%08Xu pop3c_host = p1.caps.fsu.edu service auth { unix_listener /var/run/dovecot/auth-master { mode = 0600 user = vmail } unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = uid=vmail gid=vmail home=/var/vmail/%d/%n allow_all_users=yes driver = static } protocol lda { auth_socket_path = /var/run/dovecot/auth-master log_path = mail_plugins = postmaster_address = postmaster(a)caps.fsu.edu } protocol doveadm { mail_plugins = " pop3_migration" } -- Michael Sloan Systems Administrator FSU Center for Advanced Power Systems sloan(a)caps.fsu.edu

[Dovecot] How To Remove?
by Christian Guastella 03 Jan '13

03 Jan '13

hi, i was looking to setup imap on an old PPC G5 mac i have running as webserver and gateway/firewall machine.. found a dovecot-2.1.7-0.pkg online, and it looked like the typical easy install thing.. someplace called rudix made the package.. not much there in way of instructions, but after i finally figured out where the executable had been stuck i tried it, just to see what kinda config errors would be thrown-up.. got the line below.. /usr/local/sbin/dovecot: Bad CPU type in executable so i'm guessing this means dovecot is intel-cpu only? i don't have the time or patience to read all the unix junk, and get a compiler, do all the make files etc.. been years since i did any of that, and don't want to do it again.. the pkg installer did not come with an uninstaller, and since the install is pretty much useless, is there some list of what it installed so i can get rid of it all? thanks, christian

Re: [Dovecot] Dovecot Virtual Users with Sendmail
by DormitionSkete＠hotmail.com 01 Jan '13

01 Jan '13

Well our situation is kind of like this: We've been using UW-Imap for 12-15 years, and have loved it. It has a beauty and simplicity to it that is simply wonderful. We're located in a remote part of the Rocky Mountains, and the only internet connection we can get that's faster than a dial-up is a satellite. Lousy upload speeds. Can't host our own sites here. We've been hosting our sites on one of our parishioner's servers for years; but through the years, that's become more and more problematic, and we'd like to do more with it than we currently can. We'd like to set up our own server at our guest house in town. I wanted to use OpenIndiana (Solaris) to take advantage of some of the really amazing features it has. So, I set up UW-Imap on it. Works great. Glory be to our holy God. The problem is, after I got all that working, I went to set up the users for it, and discovered the GUI for creating the users won't allow me to add any users with usernames longer than eight characters. I'm not real dependent on GUI's, and a quick search on the net told me that I can easily add the users with the long user names from the command line. So, I asked on the UW-Imap and on the OpenIndiana list for people's experience about this. Two people said they'd been using long user names on Solaris and BSD for years without any problems, while two others recommended changing to an IMAP server that supports virtual users. One of those recommended Dovecot. So I started looking at Dovecot. I'm not real keen on Sendmail, but to make matters worse, we host our own email on our server here in the mountains. Since we can't get reverse DNS set up for our satellite connection, we have to relay our emails through our parishioner's server, which does have reverse DNS, or else most people's email servers reject them as spam. We also need to be able to send and receive emails from multiple domains. So, I have to be able to figure out how to do both parts of the relay -- our part where we tell our MTA to relay it through the other host, and what will become the server at our guest house to accept those emails and relay them on to the recipients. And the multiple domain issue. I can do all this with UW-Imap and Sendmail, because we've already done all the fighting necessary to get it to work. We've been doing it for years. It just leaves us with the question of whether it's better to go with using UW-Imap on a system that's not designed to support long user names, and possibly getting bit by that, or whether it's better to fight it out trying to learn all this other stuff with a different IMAP server and MTA? Fun! I could probably get Cyrus IMAP to work with Sendmail, because I tried it briefly years ago and already have gone through the grief of figuring that out. But I didn't particularly care for it. One of the things I like most about UW-Imap -- and Dovecot shares this -- is that it's easy to backup, restore inadvertently deleted directories, and to move emails from one server to another. From what I remember, Cyrus wasn't so friendly about that. And it was more difficult to administer than UW-Imap and Dovecot. After reading the 13-page article Ken posted this afternoon, I started looking at Postfix. My impression is, that maybe this might be a good route to try. Dovecot - PostFix - and if I'm going to go through all that, I might as well go with Sieve, instead of Procmail, like we've been using for years. I used Sieve briefly with Cyrus. I've never been thrilled with Procmail. So, with all that background, if anyone would like to share any suggestions or advice, I would certainly appreciate it.

[Dovecot] dovecot crashing?
by Eric 30 Dec '12

30 Dec '12

Happy holidays! I am experiencing an issue when trying to check my mail using IMAP. with Dovecot I have tried checking my mail using a full GUI client (Thunderbird) and telnet. Both times I get disconnected before all of my messages can be downloaded and I see an error in my mail log. Here are the details: [root@cust19-1-prod-domain userqa]# dovecot --version 2.0.9 [root@cust19-1-prod-domain userqa]# dovecot -n # 2.0.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.18-164.11.1.el5 x86_64 CentOS release 5.4 (Final) disable_plaintext_auth = no login_trusted_networks = 172.19.136.0 mail_location = maildir:~/Maildir mail_max_userip_connections = 100 mbox_write_locks = fcntl mmap_disable = yes passdb { args = scheme=plain username_format=%n /etc/dovecot/users driver = passwd-file } protocols = imap ssl = no userdb { args = username_format=%n /etc/dovecot/users driver = passwd-file } [root@cust19-1-prod-domain userqa]# i try to check my mail: username@ops1-1-domain:~$ telnet cust19-1-prod-domain imap Trying 172.19.136.223...

The attachment seems small in size: Content-Disposition: attachment; filename="report_amex.xlsx"; size=20527; That means the attachment is 20527 bytes, correct?

Postfix doesn't allow external hosts to connect & relay mail, which explains what you're seeing. Why you're seeing that is better addressed on the postfix list, although you seem to have told postfix to use Dovecot for sasl auth, so maybe, since this is the Dovecot list you should send your Dovecot conf so we can see why it's not working. Also, if you ask on the postfix list you will be asked for the out-put of postfinger which can diagnose sasl problems. Simon

[Dovecot] Update 1.2 -> 2.0 ... INBOX away?
by Martin Rabl 29 Dec '12

29 Dec '12

Hi, yesterday I did an update from dovecot 1.2 to 2.0.19 (Ubuntu 10.04 -> 12.04). After fixing the configuration dovecot startups as it should, but with one error, I don't understand: the INBOX will not be delivered to the Mailclient and will not be filled by "deliver". Instead, dovecot create the two dirs "new" and "cur" directly in "Maildir". the filesystem looks now like: domain/user1/Maildir/INBOX # official INBOX domain/user1/Maildir/new # new mail domain/user1/Maildir/cur # read mail We have searched for an configuration error, but didn't found anything - or did not see one ;-) Maybe there is someone in the list, which see our error in a moment? We are using only imap/s and managesieve, no pop3. Maildir-Layout is FS. Here a snippet of our configuration: ------------ mail_home = mail_location = maildir:~/Maildir:LAYOUT=fs namespace { hidden = no inbox = yes list = yes location = prefix = separator = / subscriptions = yes type = private } namespace { list = yes location = maildir:%%h/Maildir/:INDEX=%%h/Maildir/shared/%u:LAYOUT=fs prefix = shared/%%u/ separator = / subscriptions = no type = shared } namespace { list = yes location = maildir:/srv/vmail/public:LAYOUT=fs prefix = public/ separator = / subscriptions = no type = public } protocol lda { mail_plugins = sieve autocreate } protocol imap { imap_client_workarounds = delay-newmail tb-lsub-flags tb-lsub-flags mail_max_userip_connections = 10 mail_plugins = acl autocreate imap_acl } ------------ Hope you can help! Thank you! Martin

[Dovecot] question
by mattk＠kraner.us 29 Dec '12

29 Dec '12

I just install Dovecot and postfix. When I'm pull dovecot I see in the log that its checking for mail. if a put a test message locally on the server I can pull the message down to my cell phone and other computers. But when I try to a message from gmail or aol it doesn't come in to the server. it always bounces back to the place were I sent it from

[Dovecot] mdbox: more then one altstorage
by Peer Heinlein 29 Dec '12

29 Dec '12

The mdbox-format with the altstorage-feature is quite nice and important. But we're having much more then >> 30 TB of maildata and doing an fsck on huge partitions takes too much (down-) time for our mailsystem. It would be much easier, if Dovecot would be able to use at least THREE storage-paths for his m-Files (and not just TWO like now). Having an altstorage1 and altstorage2, we would be able to move away all mails from on altstorage-mountpoint, we could put this storage-moungpoint into "maintenance" and do an fsck without Downtime for Dovecot. It would be nice having a doveadm-feature to put a altstorage-path in "maintenance-mode", so to move easily away all m-files to other alt-storage-paths and to let Dovecot know not to use this locked partition. Having even more then 3 storage-paths would be nice for huge setups: In this case we could easily use different SMALLER partitions without having just two or three huge partitions > 15 TB. The architecture of the altstorage-system is nice and simple. Wouldn't it be easily possible to look (at least) in three, then just in two places for a m-file? What about a "hash_dir"-system for the storage? What about a configuration-parameter like altstorage_dirs=4 which would mean, that there are 4 storage-mountpoints that could be addressed by "%m": mail_location = mdbox:/vmail/%d/%n/mdbox:altstorage/alt/%m/%d/%n In this case, Dovecot could easily use all existing partitions automatically "round-robin". Or maybe it would be better to tell Dovecot the partitions by: altstorage_dirs_existing = 1,2,3,4 altstorage_dirs_newmail = 1,4 so it would be very easy to tell Dovecot in which partitions he has to look for m-files and where he is allowed to save round-robin new e-mails. With this setup it's easy to put a partition in maintenance mode.

[Dovecot] dovecot 2.1.12 panic in mbox-sync.c

Hello! I use dovecot 2.1.12 locally on a 32bit Linux with an ext4 filesystem and after deleting a lot of emails from a mbox folder, I now get the following messages in the log: dovecot: imap(amied): Panic: file mbox-sync.c: line 1351 (mbox_sync_handle_eof_updates): assertion failed: (offset == 0 || offset > 31) dovecot: imap(amied): Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(+0x4559a) [0x6f68959a] -> /usr/lib/dovecot/libdovecot.so.0(+0x45611) [0x6f689611] -> /usr/lib/dovecot/libdovecot.so.0(i_fatal+0) [0x6f658fa0] -> /usr/lib/dovecot/libdovecot-storage.so.0(+0x2d707) [0x6f708707] -> /usr/lib/dovecot/libdovecot-storage.so.0(mbox_sync+0x53) [0x6f7091d3] -> /usr/lib/dovecot/libdovecot-storage.so.0(mbox_storage_sync_init+0x6d) [0x6f70936d] -> /usr/lib/dovecot/libdovecot-storage.so.0(mailbox_sync_init+0x3b) [0x6f72333b] -> /usr/lib/dovecot/libdovecot-storage.so.0(mailbox_sync+0x3f) [0x6f72347f] -> dovecot/imap(cmd_select_full+0x16b) [0x805529b] -> dovecot/imap(cmd_select+0x17) [0x8055c57] -> dovecot/imap(command_exec+0x32) [0x80596f2] -> dovecot/imap() [0x80586fd] -> dovecot/imap() [0x805880d] -> dovecot/imap(client_handle_input+0x125) [0x8058a05] -> dovecot/imap(client_input+0x60) [0x80592f0] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x44) [0x6f6981f4] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0xce) [0x6f6991ce] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_run+0x40) [0x6f697cd0] -> /usr/lib/dovecot/libdovecot.so.0(master_service_run+0x2e) [0x6f680dbe] -> dovecot/imap(main+0x279) [0x804fdd9] -> /lib/libc.so.6(__libc_start_main+0xf5) [0x6f49bad5] -> dovecot/imap() [0x804ff51] The mbox file seems to be unchanged and a .lock file remains even after stopping dovecot.

[Dovecot] dovecot testinstallation does not tell how to quit
by Robert Moskowitz 28 Dec '12

28 Dec '12

I am having problems logging in with RoundCube, so thought I should see if there were instructions for testing Dovecot login, and sure enough I found some at: wiki.dovecot.org/Testinstallation Well it works, so the problem is probably all RoundCube's, but this wiki page is missing an important line about how to end the Telnet session without killing Telnet! What is the quit/exit command? And please add this to the wiki! Oh, I just guessed it: a logout

[Dovecot] Using -module flag on sieve libs
by Dimitri 26 Dec '12

26 Dec '12

Some modern distros (Mageia, Mandriva) use -no-undefined as a default linker flag for building software. However, undefined symbols are OK if the binary being linked is a plugin. To detect plugins, build system looks for presence of "-module" libtool flag in makefiles. There are two libraries in Pigeonhole that couldn't be linked with -no-undefined: src/lib-sieve/plugins/mailbox/libsieve_ext_mailbox.la src/lib-sieve/libdovecot-sieve.la These modules do contain undefined symbols, but they are not linked against library that provides them. It would be good if corresponding makefiles contained "-module" flags, so that build system could selectively turn off that -no-undefined linker flag. Please see proposed patch (attached). Thanks, Dimitri Mageia Linux packager

[Dovecot] Postfix/mysql/dovecot - Understanding password encryption
by Robert Moskowitz 25 Dec '12

25 Dec '12

I am switching from a fedora/postfix/mysql/couriermail/squirrelmail to Centos/.../dovecot/roundcubemail and adding postfixadmin to the mix. My tutorial before was an earlier version (on F14) of: http://www.howtoforge.com/virtual-users-and-domains-with-postfix-courier-my… Now I am using http://www.campworld.net/thewiki/pmwiki.php/LinuxServersCentOS/Cent6VirtMai… to get me started. I am up to roundcubemail setup and am stumbling to understand what the author here is doing with encrypted passwords, so felt it was time to delve deeper into this. My old setup uses mysql-crypt for the password. MYSQL_CRYPT_PWFIELD password and users could be added to the table with: INSERT INTO `users` (`email`, `password`, `quota`) VALUES ('sales(a)example.com', ENCRYPT('secret'), 10485760); But where this was all simple and no choices, I get to figure out what to do with my dovecot setup. Some of the 'secret' is hinted at in postfixadmin's config.inc.php: // Encrypt // In what way do you want the passwords to be crypted? // md5crypt = internal postfix admin md5 // md5 = md5 sum of the password // system = whatever you have set as your PHP system default // cleartext = clear text passwords (ouch!) // mysql_encrypt = useful for PAM integration // authlib = support for courier-authlib style passwords // dovecot:CRYPT-METHOD = use dovecotpw -s 'CRYPT-METHOD'. Example: dovecot:CRAM-MD5 $CONF['encrypt'] = 'md5crypt'; Where is there information on the different choices and how to choose. Is it as 'simple' as setting up postfixadmin to control the password encryption format then 'inform' dovecot in the dovecot-mysql.conf with default_pass_scheme = MD5-CRYPT Thank you for any pointers.

[Dovecot] Understanding Sockets
by Tim Smith 22 Dec '12

22 Dec '12

Hi, Just trying to consolidate my knowledge of Dovecot and I want to understand various things rather than just key out lines of config in dovecot.conf with the hope of it working. What I wanted to clarify is my understanding the "socket listen" section of the config file. From my limited understanding, this section details how other processes can access the userdb defined in Dovecot. The master socket is used for "internal" processes which is mainly dovecot-lda so that when Dovecot receives mail it knows where to deliver it and client is defined for "external" processes, for example Postfix who would use the info to determine if a user existed. Would you say this is a fair (albeit) dumbed down!!) synopsis of sockets and their purpose? Thanks in advance! Tim

[Dovecot] Non-dovecot user looking for feedback
by Chris Ross 21 Dec '12

21 Dec '12

I've been using UW-IMAPd for neigh on forever (at least since 2001). But, as it's basically stalled, and I'm about to update the hardware that is my mail server, I thought it was time to review existing open-source IMAP servers. Dovecot is the top three in my looking. The other of the top three candidates, because I know of people who've used it, is Cyrus IMAP. So, I should note that my thoughts are "uw-imapd, because I already know how to use it", "Cyrus, because someone I know/trust liked it years ago", and dovecot, because "it seems stable, professional, and to meet all of my needs". I guess the biggest question I have is how files/folders are stored in the filesystem. uw-imapd has a "mbx" format that all of my folders are in, and also has support for mbox and maildir (i think). mbx had some advantages for speed access, which would be unimportant I assume with dovecot's indexes, but IIRC there was also some reason the mbox format coped poorly with multiple clients accessing the same folder at the same time. So, am I right that dovecot supports only the "one big full file" mbox format, and the maildir format? And if so, is it known to allow multiple simultaneous IMAP clients to access and monitor and/or modify the same folder simultaneously? After those questions, it's just a "what do you think the pros and cons of each are?" I know asking in this forum, that I will get most if not all votes for Dovecot. And that's fine, as long as you have specific reasons why it would be better for someone with only a handful of users and minimal time available to administer the systems in question. Thanks! I appreciate any and all feedback. - Chris

[Dovecot] backtrace from postgres dict
by Steffen Kaiser 20 Dec '12

20 Dec '12

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, since I enabled ACLs I get following backtrace. It looks like that it happens if the ACLs had been changed only. Also, it looks like that it always happens 1 minute after last "dict: Info: pgsql(localhost): Connected to database dovecot", no matter if the user is logged in (and idle) or logged off. Postgres logs: "could not receive data from client: Connection reset by peer" and "unexpected EOF on client connection". Is there some TCP keep alive issue? Postgres is using the "system default" for TCP keep alive. I'm currently testing ACLs via telnet, so the activity with the ACL dict is pretty low, hence, an idle timeout would make much sense. # ../../sbin/dovecot --version 2.1.10 (a4f02f6c0d32) dict connect string: connect = host=localhost dbname=db user=user 2012-11-28 10:03:39 dict: Info: pgsql(localhost): Connected to database dovecot 2012-11-28 10:03:39 dict: Info: pgsql(localhost): Connected to database dovecot 2012-11-28 10:03:39 dict: Info: pgsql(localhost): Connected to database dovecot 2012-11-28 10:03:58 IMAP(user) [22922]: Info: Disconnected: Logged out in=23 out=763 2012-11-28 10:04:41 dict: Panic: file driver-pgsql.c: line 84 (driver_pgsql_set_state): assertion failed: (state == SQL_DB_STATE_BUSY || db->cur_result == NULL) 2012-11-28 10:04:41 dict: Error: Raw backtrace: /usr/local/dovecot-2.1.10/lib/dovecot/libdovecot.so.0(+0x4857a) [0x7f91f511157a] -> /usr/local/dovecot-2.1.10/lib/dovecot/libdovecot.so.0(+0x485c6) [0x7f91f51115c6] -> /usr/local/dovecot-2.1.10/lib/dovecot/libdovecot.so.0(i_error+0) [0x7f91f50e4eaf] -> dovecot2.1/dict() [0x40aa36] -> dovecot2.1/dict() [0x40aa91] -> dovecot2.1/dict() [0x40bed3] -> dovecot2.1/dict() [0x409504] - -> dovecot2.1/dict(sql_db_cache_deinit+0x20) [0x408a60] -> dovecot2.1/dict(main+0x169) [0x405a59] -> /lib/libc.so.6(__libc_start_main+0xfd) [0x7f91f4b5cc8d] -> dovecot2.1/dict() [0x404bb9] 2012-11-28 10:04:41 dict: Fatal: master: service(dict): child 22923 killed with signal 6 (core not dumped) - -- Steffen Kaiser -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQEVAwUBULXbiGoxLS8a3A9mAQI9Ywf/YItPO4fFT70HcuwCkDXgx0Sn7CEyXu2j +1VzOu3R/TMs1rcxYJIvWiei6Nk3wXywzQl84POadJn61Yf2NuT80nMxwBsBbgio e+0oRE9JNVSjtvX5l7kehEdUDQjqRRKyrhWG9KDlpjWidGsYh7pQg0rDtp3UwG57 HuSBMiBAZ9t9sC2DXjn9wT9vweH3gMIhc/K5U0BLF5JG/K8UAKc5QBUgezjIYzvn KP90TJ4RoZ2vnPzmWfeIsjffRBvvC6UUgWmU02e2H9xJxzF32Nix0s8YWi7G91sH Ei057HW5NsKNDtp6B5fYk+xCpC6ucQiwFSr/ZG+uZCAdtTd2qmf60g== =tQYK -----END PGP SIGNATURE-----

Hello! dovecot version 2.1.7 I set up vacation with sieve.

[Dovecot] Problems trying to add dspam delivery to dovecot LDA to working Postfix/Dovecot server. No passdb.
by Brian Jarrett 20 Dec '12

20 Dec '12

Hello list, I'm really hoping someone can point me in the right direction on this. I set up a server using Postfix with LDAP lookups to Active Directory. Postfix delivers to maildir. Dovecot IMAP and POP are working correctly using PAM Kerberos to authenticate via Active Directory. I want to add spam filtering, so I'm trying to set up Postfix to use dspam which is then supposed to use Dovecot LDA to deliver messages to the mailbox instead of having Postfix deliver to the Maildir. I can't get any deliveries to Dovecot LDA to get past passdb lookup. When I run /usr/lib/dovecot/deliver -f bjarrett(a)garfield16.org -d bjarrett(a)metcalfexcavation.com I get: Dec 19 20:57:55 mxserver2 dovecot: auth: Debug: master in: USER#0111# 011bjarrett(a)metcalfexcavation.com#011service=lda Dec 19 20:57:55 mxserver2 dovecot: auth: Debug: password( bjarrett(a)metcalfexcavation.com) passdb doesn't support credential lookups Dec 19 20:57:55 mxserver2 dovecot: auth: Error: static( bjarrett(a)metcalfexcavation.com) passdb doesn't support lookups, can't verify user's existence Dec 19 20:57:55 mxserver2 dovecot: auth: Debug: master out: FAIL#0111 Dec 19 20:57:55 mxserver2 dovecot: lda: Error: user bjarrett(a)metcalfexcavation.com: Auth USER lookup failed Dec 19 20:57:55 mxserver2 dovecot: lda: Fatal: Internal error occurred.

[Dovecot] Maildir hardlinks with sieve
by Benedetto Vassallo 19 Dec '12

Hi all, First of all, excuse me for my previous posts (Maildir hardlinks). Today I realized the following issue. Maildir hardlinks works OK on dovecot 2.1.10 without sieve. If set sieve plugin in dovecot-lmtp hardlinks stop working. Is there a way to have both sieve and hardlinks working?

[Dovecot] namespace subscription problem
by Holger Hegmanns 19 Dec '12

19 Dec '12

Hi all, my problem seems to be a cosmetic one (again). According to the docs: subscriptions: "yes" (default) if this namespace should handle its own subscriptions. If "no", then the first parent namespace with subscriptions=yes will handle it. Therefore is no way to create the following scenario: three namespaces (private, shared, public) the private namespace has to handle its own subscriptions the private namespace setup with "prefix = INBOX." the both shared and public namespace setup with "subscriptions = no" cause there is no so called "parent" namespace. Private namespace setup with "prefix = " works fine, but that's not what I want. namespace { type = public separator = . prefix = public. location = maildir:/var/spool/dovecot/vmail/public subscriptions = no } namespace inbox { type = private separator = . prefix = INBOX. inbox = yes } namespace { type = shared separator = . prefix = user.%%u. location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u subscriptions = no list = children } Any chance that the private namespace can subscribe to shared mailboxes with the principals above? ... Few hours later. Added a default namespace without any prefix: namespace { prefix = separator = . hidden = yes subscriptions = yes } Subscriptions works as expected, but when I telnet to dovecot now the LSUB command shows all boxes beneath the INBOX as well as without the prefix: b lsub "" * * LSUB () "." "Sent" * LSUB () "." "Templates" * LSUB () "." "Trash" * LSUB () "." "Drafts" * LSUB () "." "INBOX.Sent" * LSUB () "." "INBOX.Templates" * LSUB () "." "INBOX.Trash" * LSUB () "." "INBOX.Drafts" * LSUB () "." "INBOX.user.bar.Sent" * LSUB () "." "user.bar.Sent" b OK Lsub completed. Completely stuck Holgert

[Dovecot] migration to dovecot pop3
by Rajesh M 19 Dec '12

19 Dec '12

hi i am planning to migrate from qmail pop3 to dovecot pop3 the number of users on the server is large over 5000 also data volume is large - over 3.5 tb -- ie many users several 1000s of emails in their inbox email clients used are outlook / outlook express / windows mail, etc my questions 1) will the migration cause all the emails on the server to re-download 2) can dovecot be configured to allow only one download at a time - pop3 locking with time out setting that can be customized 3) can dovecot pop3 be configured so that it will allow download of emails only of the last say 15 days ie even if the same pop3 user is configure on another machine it will download only messages of the last 15 days 4) has anybody migrated from qmail pop3 to dovecot pop3 successfully without emails being downloaded again thankyou very much in advance rajesh

[Dovecot] Upload / migrate old mails: iPhone shows oldest mails first
by Denny Schierz 19 Dec '12

hi, I've got a very strange behavior: I uploaded old mails from a local folder (thunderbird / osx) to my Dovecot (Debian Squeeze) and now, the iphone (ios6) show the oldest mails first. The only thing I can imagine is, that Dovecot got from Thunderbird the newest mails first and last the old mails, so that in the last mdbox are the old one. So, if it is correct, how can I fix it? cu denny

[Dovecot] Too many imap connections in state "idling"
by 3.listas＠adminlinux.com.br 19 Dec '12

19 Dec '12

Hi, I have a "Ubuntu12.04 + dovecot-2.0.19" configuration in my server. My mailbox server is shared by ~ 10k domains. It works fine with ~50k accounts. On average, my server has about 6K simultaneous imap connections during office hours. But I've noticed that this server has an average of approximately 4k connections in state "idling". On other Dovecot servers the average connections in state "idling" is only 10%. My doveconf -n: http://thiagoh.prv.digirati.com.br/doveconf-n.txt Can someone help me? Thanks -- Thiago Henrique adminlinux.com.br

[Dovecot] Dsync help, new attempt
by Torbjorn Astlind 19 Dec '12

19 Dec '12

I observe that dsync fills Maildir correctly incl. cur, if I delete Maildir just before dsync runs. Can the failed mbox to Maildir conversion be caused by dovecot creating Maildir automatically if a client connects to dovecot? Should dovecot be shutdown when running dsync?

[Dovecot] Advice on sieve vacation for aliases
by Marcio Merlone 19 Dec '12

19 Dec '12

Greetings, I have a working mail server with sieve 1:1.2.9-1ubuntu6.5 working just fine. My commercial dept. has asked me to set a vacation message for comercial(a)domain.tld, but this is an alias to jhon(a)domain.tld and meggie(a)domain.tld. I have created a sieve_global_path = /etc/dovecot/global.sieve and it works, but not the intended way: it sends two vacation messages, each From: each employee, and not From: comercial(a)domain.tld alias. Is there how to make dovecot send only one vacation message From: comercial(a)domain.tld or will I have to survive with one message from jhon and another from meggie? Also, is there how to have a dovecot.lda-dupes for the alias instead the users? /etc/dovecot/global.sieve: require ["vacation"]; # rule:[Ferias coletivas] if anyof (header :contains "To" "comercial(a)domain.tld") { vacation :days 7 :subject "Férias coletivas de 20/12/2012 a 07/01/2013" text: bla bla bla. ; stop; } Thanks in advance and nice holidays. -- Marcio Merlone

[Dovecot] Adding a parameter to dovecot's deliver to get a meaningful return value
by Cyril RUSSO 18 Dec '12

18 Dec '12

Hi, First, please forgive me as I'm not subscribed to the list. I'm using Dovecot 2 (2.1.7) for serving my local maildir. This maildir is filled by an external process, fetching & merging mails from different sources that's outside this scope (but it's working). Dovecot is thus acting as a MTA, but more as a MDA. I've a web client running on the server, and it connects to Dovecot to get the mails. I've configured this web client & dovecot to use sieve to filter the mails. I know that since Dovecot does not actually deliver the messages, it's not the expected behavior. Anyway, I can use the "deliver" software in your suite for passing sieve's rules on each message in my maildir, and it's almost working. I've a cron job that run deliver on each message of my maildir, but I'm a bit puzzled now. Basically, I'm not able to figure out if a message was matched by a sieve filter or not. I'm a bit disappointed by two things: 1) Sieve's reject doesn't make "deliver" to return an error, so a sieve rule chain ending in "reject" can't be detected from my cron's script. I wonder it's due to the step deliver is supposed to be run (after a mail is already accepted). 2) "deliver" doesn't have a method to find out if it processed the given mail as input. Basically, would it be possible to either add a parameter to "deliver" (for example: "--fail-on-discarding") so it would fail if the sieve rules discard or reject (/ereject) the mail ? That way, I could detect the failure in my script, and know that I don't need to delete the initial mail since it was not filtered. Or, thought differently, I wonder if "deliver" could open a socket/pipe/file whatever, and write the number of processed mails in there (or using a "--return-processed-mail"), so a sieve rule ending with "delete", would be detectable by my script. Best regards, -- Cyril

[Dovecot] Clear-text ldap passwords: {CLEAR} scheme?
by Kristof Bajnok 18 Dec '12

18 Dec '12

Hi, if I read the documentation correctly, the clear-text password storage scheme in Dovecot is called PLAIN. Unfortunately, in Sun LDAP Directory Server I have to specify them as "{CLEAR}" [1]. Is it somehow possible to make Dovecot recognise "{clear}foobar" passwords as plaintext? Now I get: auth: Error: ldap(username): Unknown scheme clear Thanks, Kristof [1]: http://docs.oracle.com/cd/E19850-01/816-6699-10/confattr.html#passwordStora…

[Dovecot] dovecot-lda (2.1.12) segfaults
by Joseph Tam 18 Dec '12

18 Dec '12

We uograded our dovecot from version 2.1.10 -> 2.10.12, but within the first hour of use, dovecot-lda would segfault during delivery. This left a lock file lying around causing the user's mail readers to hang; much hilarity ensues. All further deliveries to the same user will result in a crash. The only thing that fixes this condition is to blow away the user's INBOX cache index. Reindexing with "doveadm index" does not fix anything. I've installed a test version with one user's problematic INBOX cache indices and ran gdb dovecot-lda (gdb) run -t testuser </dev/null and it crashes with the following backtrace Program received signal SIGSEGV, Segmentation fault. 0xff2a0440 in mail_cache_header_fields_read (cache=0x5c120) at mail-cache-fields.c:323 323 if (field_hdr->size < sizeof(*field_hdr) + (gdb) bt #0 0xff2a0440 in mail_cache_header_fields_read (cache=0x5c120) at mail-cache-fields.c:323 #1 0xff29e8bc in mail_cache_compress_locked (cache=0x5c120, trans=0x63ce8, unlock=0xffbfeeef) at mail-cache-compress.c:361 #2 0xff29efd0 in mail_cache_compress (cache=0x5c120, trans=0x63ce8) at mail-cache-compress.c:489 #3 0xff2a3df4 in mail_cache_transaction_compress (ctx=0x5dac0) at mail-cache-transaction.c:180 #4 0xff2a4084 in mail_cache_transaction_open_if_needed (ctx=0x5dac0) at mail-cache-transaction.c:241 #5 0xff2a6e60 in mail_cache_field_want_add (ctx=0x5dac0, seq=1, field_idx=12) at mail-cache-transaction.c:1048 #6 0xff27e8e8 in index_mail_parse_header_register_all_wanted (mail=0x5e6b0) at index-mail-headers.c:175 #7 0xff27ec90 in index_mail_parse_header_init (mail=0x5e6b0, headers=0x0) at index-mail-headers.c:230 #8 0xff27f5c8 in index_mail_cache_parse_init (_mail=0x5e6b0, input=0x63760) at index-mail-headers.c:376 #9 0xff2299cc in mbox_save_get_input_stream (ctx=0x5dde8, input=0x62ed0) at mbox-save.c:411 #10 0xff22a084 in mbox_save_begin (_ctx=0x5dde8, input=0x62ed0) at mbox-save.c:520 #11 0xff24e9c0 in mailbox_save_begin (ctx=0xffbff514, input=0x62ed0) at mail-storage.c:1652 #12 0xff23f138 in mail_storage_try_copy (_ctx=0xffbff514, mail=0x54cd8) at mail-copy.c:68 #13 0xff23f23c in mail_storage_copy (ctx=0x5dde8, mail=0x54cd8) at mail-copy.c:93 #14 0xff24ec28 in mailbox_copy (_ctx=0xffbff670, mail=0x54cd8) at mail-storage.c:1721 #15 0xff24ec98 in mailbox_save_using_mail (ctx=0xffbff670, mail=0x54cd8) at mail-storage.c:1730 #16 0xff388070 in mail_deliver_save (ctx=0xffbff8a8, mailbox=0x13fe8 "INBOX", flags=0, keywords=0x0, storage_r=0xffbff83c) at mail-deliver.c:317 #17 0xff38869c in mail_deliver (ctx=0xffbff8a8, storage_r=0xffbff83c) at mail-deliver.c:403 #18 0x00012d08 in main (argc=3, argv=0xffbff964) at main.c:434 I dumped the value of field_hdr, and it has some bogus value (gdb) p field_hdr $1 = (const struct mail_cache_header_fields *) 0x20 Other observations - blowing away the indices does not fix it permanantly.

Is this enough debug info to work your magic, Timo? I can supply the cache data if you neded it. It's compiled on a Solaris10. Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] NFS, deleting folder issue

Hi there, I use dovecot on a server with some Nightmare File Systerm (aka NFS) storage. When I delete a folder, its content gets deleted, but the folder itself does not.

Now, the question: Is there a *magic* function that closes "dovecot.index.log" that I can call before delete_dir()? I tried mailbox_log_close() but it didn't help. Thanks a lot. p.s. Please don't suggest that I should not use NFS! I know that, and I don't really like NFS, but I have no other choice. Catalin Petrescu <catalin.petrescu gmail com>

[Dovecot] Manually creating dovecot- files after isync/mbsync mirror
by Dale Gallagher 18 Dec '12

18 Dec '12

Hi everyone I'm using isync 1.0.5 patched to do recursive folder listing and mirroring mail from an external party's IMAP server to a local Maildir, which will be accessed by Dovecot 2.0.9. In order to prevent IMAP clients from re-downloading their mail, when connecting to Dovecot, I'm busy writing a script to generate appropriate dovecot-uidlist and dovecot-uidvalidity files, per Maildir. isync stores the uid in the filename, so that's extractable, per message, and the uidvalidity and current max uid are stored in a file .uidvalidity, in each Maildir. I've read the docs here: http://wiki2.dovecot.org/MailboxFormat/Maildir Regarding the dovecot-uidlist header (first line) - I've tried to search for and figure out what exactly is meant by the "mailbox global uid" and once I do, how to manually generate the 128 bit hex variation of it? Could someone elaborate on this, please. How would omitting the global uid field, beginning with G, affect remote clients' syncing of mail? Is this field mandatory? I also see that Dovecot's uidvalidity is of the form 4df8a4e2, whereas isync uses an integer. I'd appreciate it if someone could elaborate on what Dovecot uses and whether I can convert one to the other? I'll post the full solution, once complete, and working. Thanks. Dale

Re: [Dovecot] Automatically Cleaning Kerberos Credential Cache Files

18 Dec '12

Ben Morrow writes: > In any case, it's likely that the delivery process looks in the user's > home directory even if delivery is to a separate mail spool, unless > you've taken steps to prevent this. I can confirm this. I think the reason is that dovecot changes to the user's home directory so that it has a place to dump core. This causes problem for my setup since I user per-user NFS mounts, so a delivery to an internal mailing list caused hundreds of NFS automounts. I patched this behaviour out, but there is probably a more elegant solution (unset MAIL_STORAGE_SERVICE_FLAG_ENABLE_CORE_DUMPS? How?).

[Dovecot] Removing configured SSL certificate file from disk while Dovecot is running spams syslog
by Nils 18 Dec '12

18 Dec '12

Hi! [root@mikan ~]# dovecot --version 2.1.12 When I remove the SSL certificate from disk while Dovecot is running, it spams syslog with the following log message over and over: Dec 6 17:41:41 mikan dovecot: config: Fatal: Error in configuration file /etc/dovecot/conf.d/10-ssl.conf line 12: ssl_cert: Can't open file /etc/ssl/private/dovecot.pem: No such file or directory Dec 6 17:41:41 mikan dovecot: config: Fatal: Error in configuration file /etc/dovecot/conf.d/10-ssl.conf line 12: ssl_cert: Can't open file /etc/ssl/private/dovecot.pem: No such file or directory Dec 6 17:41:41 mikan dovecot: config: Fatal: Error in configuration file /etc/dovecot/conf.d/10-ssl.conf line 12: ssl_cert: Can't open file /etc/ssl/private/dovecot.pem: No such file or directory [...] Reporting that the certificate went away is fine and useful, but spamming the syslog over and over with hundreds of entries per second(!) is annoying. :( I know what I'm doing, so reporting it once per connection attempt or something is enough. Even if Dovecot just decides to terminate, that would be fine. But a denial of service attack on syslog is not nice. Configuration output follows below. All the best, Nils [root@mikan ~]# dovecot -n # 2.1.12: /etc/dovecot/dovecot.conf # OS: Linux 3.5.4-1-ARCH x86_64 auth_failure_delay = 5 secs auth_mechanisms = plain login auth_verbose = yes listen = *,:: login_greeting = mail_location = maildir:~/.maildir namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { driver = pam } protocols = pop3 service pop3-login { inet_listener pop3 { port = 110 } inet_listener pop3s { port = 995 ssl = yes } } service pop3 { process_limit = 10 } ssl_cert = </etc/ssl/private/dovecot.pem ssl_key = </etc/ssl/private/dovecot.key userdb { driver = passwd } protocol imap { imap_idle_notify_interval = 2 mins mail_max_userip_connections = 5 } protocol pop3 { mail_max_userip_connections = 5 pop3_logout_format = pop3_save_uidl = no pop3_uidl_format = %08Xu%08Xv }

[Dovecot] Documentation of Redis and Memcache Backends
by Urban Loesch 18 Dec '12

18 Dec '12

Hi, in the release notes of 2.1.9 I read that dovecot supports memcache and redis backends for userdb/passdb authentication. This is very interesting for me and should reduce queries and database load of our mysql servers. My idea is to use memcache or redis in our IMAP/POP3 proxies in front of our backend servers. So I would like to try out if it's possible to store proxy information of our backends. For example the backend ip adress. But in the wiki I found only a few configuration settings for redis backend. http://master.wiki2.dovecot.org/AuthDatabase/Dict Also the mentioned example config file "dovecot-dict-auth.conf.ext" with full list of configuration options does not exits in the source of 2.1.11. Have you any idea where I can find the full info or any howtos? Many thanks and regards Urban

[Dovecot] Error: unlink_directory(.../lucene-indexes) with doveadm index
by Fred Kilbourn 18 Dec '12

18 Dec '12

Hi, Per discussion on this previous thread: http://dovecot.org/pipermail/dovecot/2012-October/068849.html I am updating search indexes on all my mailboxes via a nightly cronjob that runs: doveadm index -A '*' The problem we're running into is that random mailboxes will throw the following error during the update (sanitized to conceal actual domain name): doveadm(user(a)domain.com): Error: unlink_directory(/var/spool/mail/domain.com/user/sdbox/lucene-indexes) failed: Permission denied We have around 250 domains on the server, with a handful of mailboxes on average in each domain. We get this for a varying number of total mailboxes (1 to 6 every night). It is common for the same mailbox to show up a few days in a row and then stop throwing the error. The script is running as root, so there shouldn't be any file level permissions. Any thoughts on the root cause of these errors? What can I provide to help further diagnose? Thanks, Fred Kilbourn

[Dovecot] Dovecot version 1.2.17
by Philip Coackley 18 Dec '12

18 Dec '12

Hello, I am currently performing retrospective upgrades to an old ubuntu 9.10 Karmic Kola server. I need to upgrade dovecot 1.1.11 to 1.2.17 then to 2.0 etc. I have downloaded the binaries and run ./configure make make install. Dovecot compiles OK however I can not get the ./configure options to install at the following locations: executable: /usr/sbin/ config: /etc/dovecot/ Question: What are the ./configure options to do this? What are the ./configure options used to create the executable for unbuntu? (especially 9.10 if different). Reason for upgrade is auth-login errors every 2-3 weeks with 1.1.11 - looking at the release descriptions, this should fix this and the memory leaks! Phil Coackley

Hello Serveral of our clients are running into a problem relating to Gmails change in their "Check mail from other accounts (using POP3):". It seems related to the response dovecot sends back on a connection. Gmail is checking for a +OK in the header, however dovecot is sending OK without a prefix of +. Here is the response from Gmail webmail "Missing +OK response upon connecting to the server: * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE AUTH=PLAIN] Dovecot ready." Here is dovecot header on a pop3-ssl connection * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE AUTH=PLAIN AUTH=LOGIN] Dovecot ready. Who's end is this problem on? Google's, dovecots? Anyway to enable the response to include a +? Thanks Josh

I still run using mbox, and have not had a problem with corruption, however, this is probably owing to our modest IMAP demand and careful coordination of file locks among all the different MUAs. You're better off with Maildir and other formats, that are better designed for simultaneous access. There are other good reasons to switch formats. Dovecot also supports its own mdbox/sdbox for high performance: its a hybrid that tries to incorporate the best of both words. More info http://wiki2.dovecot.org/MailboxFormat > After those questions, it's just a "what do you think the pros and cons > of each are?" I can't speak to the other software you are looking at, but two factors I found to be particularly good: - flexibility: you can get almost every oddball setup to work. Migration from uw-imapd is fairly easy, but then again, uw-imapd didn't have a lot of knobs to turn. Plugins are available that extends its functionality. - support: this mailing list is great, and Timo is an absolute wizard in getting bugs fixed. (Note: I am shamelessly buttering him up so that he fixes the outstanding bug I reported!) Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] need help with dovecot-lda
by Andreas Meyer 16 Dec '12

16 Dec '12

Hello all! Some month ago I upgraded our dovecot installation from version 1.0.5 to version 2.1.7 without having any trouble. Postfix is delivering email directly per virtual transport to the maildirs and mailboxes of the users in /var/spool/vhosts/domains/.... Now I want to use dovecot-lda and created a new entry in the master.cf of postfix. dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/libexec/dovecot/dovecot-lda -f ${sender} -d ${recipient} It is not clear to me, how the dovecot-lda is started bei dovecot and you it finds the socket dovecot postfix created. The dovecot.conf looks like this; # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 2.6.22.5-31-bigsmp i686 openSUSE 10.3 (i586) ext3 auth_verbose = yes disable_plaintext_auth = no log_path = /var/log/dovecot1 mail_location = mbox:/var/spool/vhosts/%d/dovecotprivate/%n:INBOX=/var/spool/vhosts/%d/%n !include /etc/dovecot/conf.d/*.conf passdb { args = /etc/dovecot/passwd driver = passwd-file } userdb { args = /etc/dovecot/passwd driver = passwd-file } ssl_cert = < /etc/dovecot/ssl/hostcert.pem ssl_key = < /etc/dovecot/ssl/hostkey.pem #verbose_ssl = yes plugin { quota = maildir:User quota quota_rule = *:storage=500MB # 10% of 1GB = 100MB quota_rule2 = Trash:storage=+10%% # 20% of 1GB = 200MB # quota_rule3 = Spam:storage=+20%% autocreate = Trash autocreate2 = Drafts autocreate3 = Sent autosubscribe = Trash autosubscribe2 = Drafts autosubscribe3 = Sent } I set soft_bounce = yes in main.cf of postfix and delivery of mail fails with Dec 14 16:13:34 delta postfix/virtual[14082]: BBC0F1B31294: to=<xyz(a)anup.de>, relay=virtual, delay=395, delays=395/0.01/0/0.13, dsn=4.1.1, status=SOFTBOUNCE (unknown user: "xyz(a)anup.de") This is the relevant part of the main.cf: dovecot_destination_recipient_limit = 1 virtual_mailbox_domains = anup.de bit-corner.de bitcorner.de baubetreuung-meyer.de saxelektro.de virtual_mailbox_base = /var/spool/vhosts #virtual_mailbox_maps = hash:/etc/postfix/vmailbox #virtual_minimum_uid = 100 #virtual_uid_maps = static:5000 #virtual_gid_maps = static:5000 virtual_mailbox_limit = 524288000 virtual_transport = dovecot I don't get it right.

I am missing somthing but don't know what. Any help is appreciated! Andreas

[Dovecot] Dovecot "sleep" for short snapshots
by Peer Heinlein 15 Dec '12

15 Dec '12

Making consistent backups from Dovecot with mdbox requires a snapshoted filesystem with (at least) a short Downtime for Dovecot. I'd like to avoid killing several thenthousand IMAP-sessions for 60 seconds. Users don't like that... And the admin dislakes that too... What about a "short sleep" mechanism for Dovecot, where all writes are finished and new writes are easily delayed? I'd like to following process: *) "doveadm sleep" puts Dovecot in sleep-Mode: -- All existing writes are finished (before "doveadm sleep" is allowed to exit) -- All new writes are simply delayed -- All readonly-operations could work normally, so users can fetch and read mails *) The the admin can create a LVM-/SAN-snapshot of the filesystems *) "doveadm unsleep" will finish the magic Overall the whole process will take just some seconds. Users will recognize a simple write-delay, but they can work normally and the aren't unconnected at all. If the snapshot is really fast the users won't recognize the whole situation at all.

[Dovecot] Copying just the folders to new Dovecot server?
by Bjørn T Johansen 14 Dec '12

14 Dec '12

I am setting up a new Dovecot server and I want to start from scratch, i.e. with an empty mailbox. But I want to have the same folders in my new mailbox that I have in my old. Is there a way to create these folders without manually creating one by one?

[Dovecot] More detail re dovecot-uidlist and -uidvalidity files
by Dale Gallagher 13 Dec '12

13 Dec '12

Regarding the dovecot-uidlist header (first line) - I've tried to search for and figure out what exactly is meant by the "mailbox global uid" and once I do, how to manually generate the 128 bit hex variation of it? Could someone elaborate on this, please. How would omitting the global uid field, beginning with G, affect remote clients' syncing of mail? Is this field mandatory? Would "3 V$uid_validity N$next_uid" be sufficient to ensure that clients don't re-download everything? I also see that Dovecot's dovecot-uidvalidity is of the form 4df8a4e2, whereas the IMAP syncing utility which I'm using (isync) uses an integer. I'd appreciate it if someone could elaborate on what Dovecot uses and whether I need to convert one to the other (ie. after syncing with isync, do I need to convert it to work with Dovecot? Thanks.

Re: [Dovecot] number of imap connection

It's typical. Some popular mail readers open about 5, some more, some less. I set my mail_max_userip_connections at 12 even though there are some users who regularly bump up against this. They don't seem to notice -- dovecot probably bumps off the least recently used connection and their mail reader reconnects if it needs to open that mailbox again. Joseph Tam <jtam.home(a)gmail.com>
