[Dovecot] Authentication process holding open filehandles
by George Barnett 07 May '12

07 May '12

Hi, We're using dovecot to provide pop3 for a number of mailboxes. The setup is pretty simple: Each user / domain has a mailstore in /data/mailstore/<domain>/<user>/Maildir (backed by NFS). Passwords are in simple passwd-file format in the top level domain directory eg: # cat /data/mailstore/foo.com/.passwd user:{plain}password The passdb setup looks like this. passdb { args = username_format=%n /data/mailstore/%d/.passwd driver = passwd-file } The problem we're having is that when we want to remove a domain from the system and we go to rm -rf /data/mailstore/<domain>/ we are unable to because the auth process is still holding onto the file handles for the password file. Can somebody suggest an alternative pattern that I could use for storing password files? Ideally, we'd avoid one large file to prevent locking issues and would also keep the passwd-file setup since it's simple. It would be possible to have the password files in a separate dir, but over time I'm guessing that would lead to nfs turds? Easy to clean up I suppose, but maybe there's a simpler solution I'm missing? George

[Dovecot] per user sieve after filters
by Andre Rodier 05 May '12

05 May '12

Hello, Thanks for dovecot, as it's still the best mail server. I'd like to use per users sieve_after scripts. Can I put in my dovecot config file, something like that: sieve_after = %h/Mails/Sieve/After/ It would be very useful for me, as I'd like to add vacation script to be executed from this place. Kind regards, André.

[Dovecot] Shared INBOX change in v2.1.6?
by Timo Sirainen 04 May '12

04 May '12

Previously Dovecot has shown shared INBOX like: * LIST (\HasChildren) "/" "shared/tss2" * LIST (\HasNoChildren) "/" "shared/tss2/INBOX" * LIST (\HasNoChildren) "/" "shared/tss2/foo" The last change in hg makes it return simply (same as with Cyrus): * LIST (\HasChildren) "/" "shared/tss2" * LIST (\HasNoChildren) "/" "shared/tss2/foo" This behavior could be made optional, but does anyone actually want it to work the old way (and why)? I'd rather not add an option that isn't useful to anyone. I think older Dovecot versions have allowed opening both shared/tss2 and shared/tss2/INBOX, but at least in v2.1 that code was broken. With the last change it's still possible to open both of them, the shared/tss2/INBOX just isn't visible in LIST output.

[Dovecot] dovecot sasl with postfix: SASL LOGIN authentication failed: Connection lost to authentication server
by David Jonas 04 May '12

04 May '12

When using dovecot (2.1.5) sasl with postfix (2.8.4) behind nginx smtp proxy I am seeing a ton of errors of the form: postfix/smtpd[7731]: warning: unknown[192.168.0.6]: SASL LOGIN authentication failed: Connection lost to authentication server Nothing is printed by dovecot in the logs regarding the error. It seems that dovecot just hung up on postfix. (side note: no, can't use xclient in nginx/postfix. But perhaps soon.) After much digging I thought I solved it with: login_trusted_networks = 172.20.20.0/24 mail_max_userip_connections = 0 This seems safe enough because dovecot is only providing sasl to postfix, no connections to the outside world. But the error is still happening. # doveadm penalty IP penalty last_penalty last_update 172.20.20.61 1 2012-04-30 19:15:56 19:15:56 strace on the anvil process shows a lot of GETs and INCs: 18:54:06 read(14, "PENALTY-GET\t172.20.20.61\n", 397) = 25 <0.000016> 18:54:06 write(14, "1 1335837245\n", 13) = 13 <0.000029> A two minute survey showed penalty distribution: 0: 60% 1: 15% 2: 18% 3: 8% Finally I just disabled penalties with the info from http://www.dovecot.org/list/dovecot/2011-December/062631.html and that seemed to do it. Is there a better way? This took me a long time to run down so I tried to make this message detailed enough that others with similar problems will stumble upon it.

[Dovecot] doveadm mailbox: rc=0 on error
by Andreas Schulze 04 May '12

04 May '12

Hi all, I use "doveadm mailbox mutf7 -7 $folder" to convert imap foldernames to UTF-8. If $foldername is not mUTF-7 encoded, doveadm returns "doveadm(root): Error: Mailbox name not valid mUTF-7: $folder" This errormessage is printed on stderr but the returncode of doveadm is zero. I tested with dovecot-2.0.* and dovecot-2.1.* # all right: $ doveadm mailbox mutf7 -7 'gr&APw-n'; echo $? grün 0 # also all right, no mUTF-7 encoded folder: $ doveadm mailbox mutf7 -7 'gruen'; echo $? gruen 0 # wrong $ doveadm mailbox mutf7 -7 'grün'; echo $? doveadm(root): Error: Mailbox name not valid mUTF-7: grün 0 Would be nice if doveadm exit with an errorcode != 0 in that case.

Hi all, i moved from dovecot 2.0.15 (lda) to 2.1.5 with lmtp transport, all works well with the same configuration directives. But sieve_before stopped working with mail_debug=no.

I have isolated the corruption in a mailbox to 4 mdbox files. Two of these (smaller) files cause the force-resync to report a breakage and save the file as m.XX.broken. The other two (larger) files cause a crash. Is there a way I can fix these files and recover the mails? -- Daniel

[Dovecot] dovecot, ldap and multiple auth_bind_userdn
by Cédric Jeanneret 01 May '12

01 May '12

Hello List! I'm having some troubles for a client of mine: he has two ldap branches which may contain valid users for imap login... For now, dovecot is configured so that it uses the auth_bind: ======== uris = ldap://localhost:389/ auth_bind = yes auth_bind_userdn = uid=%u,ou=user,dc=org ldap_version = 3 base = dc=artemis user_attrs = user_global_uid = 8 user_global_gid = 8 pass_attrs = uid=user ## other options user_filter = (uid=%u) pass_filter = (uid=%u) default_pass_scheme = CRYPT ======== Unfortunately, I cannot manage to tell him "hey guy, uses those two branches": uid=%u,ou=user,dc=org and uid=%u,ou=external,dc=org Is there a special way to do that ? Is it even possible ? I cannot modify the ldap tree, so this option is out, unfortunately :(. My dovecot version: dovecot --version 1.2.15 Thanks in advance for your answers. Cheers, C.

[Dovecot] restoring mails and directories
by oni-neko＠gmx.net 01 May '12

01 May '12

Good day! is there an easy way to restore e.g. deleted mails and/or mail directories? let me specify: I'm running dovecot 1.2.9 on a current ubuntu lts. It is set to Maildir and I backup the folder with the users maildata nightly via rsync. now, when someone deletes a mail that they still need, and I copy it back from the backup, it will not be visible to mail clients. When I change the mailfile by a letter or so, it shows. that's easy enough, if not exactly awesome ;-) But, if said person deletes a whole folder of mails, this way to make restored mails show up becomes rather unreasonable. surely there is a better way to do this? I'd be glad for any and all hints! =) best regards silvana -- Empfehlen Sie GMX DSL Ihren Freunden und Bekannten und wir belohnen Sie mit bis zu 50,- Euro! https://freundschaftswerbung.gmx.de

[Dovecot] Dovecot dsync mail replication issues
by Reuben Farrelly 01 May '12

01 May '12

Hi, I'm trying to set up some dsync based replication between two hosts on my network. The current topology is a single server running Postfix with a single dovecot installation with a Maildir per user (only 4 users including myself). No NFS, just local system users on ext4. I am only using system users, ie no virtual users. I am using dovecot deliver to deliver mails into the Maildir's. This - being a very standard Maildir installation - all works just fine. I'm running dovecot-2.1.5 (release versions) x86_64 with Gentoo on both hosts and using key based ssh to transport the data using the root login. What I would like to do is extend the design so as to replicate the Maildirs across a second machine and in the future be able to connect via IMAP into either machine to sync mail. Two way dsync would be rather cool because I could then deliver via SMTP to either system and have changes automagically propagate - but initially just simple replication would be a good start. I was hoping that dsync would allow me to do this, but I've run into quite a number of problems while getting this to work. http://dovecot.org/list/dovecot/2012-March/064243.html ...was very useful and I've based my config on that. Initially I've tried to sync up the user Maildirs, and this has more or less worked: doveadm sync -u lyn remote:root@dustbowl.reub.net This succeeds without error on the initial sync. However if I try to run the re-sync again (such as a use case of if the sync of another Maildir takes 4 hours so I want to resync up the earlier ones again) I end up with a mysteriously named INBOX folder in both the source and destination Maildirs: drwx------ 5 lyn lyn 4096 Apr 30 19:32 .INBOX_7a86a62d465a974fb92f00003b258734 It has the basic structure of a Maildir but is empty in terms of mails: drwx------ 2 lyn lyn 4096 Apr 30 19:32 cur -rw------- 1 lyn lyn 220 Apr 30 19:32 dovecot.index.log -rw------- 1 lyn lyn 51 Apr 30 19:32 dovecot-uidlist -rw------- 1 lyn lyn 0 Apr 30 19:32 maildirfolder drwx------ 2 lyn lyn 4096 Apr 30 19:32 new drwx------ 2 lyn lyn 4096 Apr 30 19:32 tmp First question: why is this random named directory being created in the origin Maildir? Shouldn't the replication be more or less read-only in the origin Maildir? Second question: If I re-attempt a doveadm sync a second time I get this error: tornado Maildir # doveadm sync -u lyn remote:root@dustbowl.reub.net dsync-local(lyn): Error: Can't rename mailbox INBOX_7a86a62d465a974fb92f00003b258734 to INBOX: Target mailbox already exists dsync-local(lyn): Error: Can't rename mailbox INBOX to INBOX_eb15f30ea563be4b703200002bd68bb1: Renaming INBOX isn't supported. tornado Maildir # It's not clear if the second attempt has failed or succeeded, and it's a bit odd that it errors out on a directory that the dovecot sync process itself has created. Third question: Upon starting Dovecot lots of ugliness is logged in the mail log: Apr 30 19:44:59 tornado dovecot: master: Dovecot v2.1.5 starting up (core dumps disabled) Apr 30 19:44:59 tornado dovecot: doveadm(mozsync): Error: user mozsync: Initialization failed: Namespace '': mkdir(/var/www/xxx/server-full/Maildir) failed: Permission denied (euid=1016(mozsync) egid=1016(<unknown>) missing +w perm: /var/www/xxx/server-full, dir owned by 0:0 mode=0755) Apr 30 19:44:59 tornado dovecot: doveadm(mozsync): Error: sync: User init failed Apr 30 19:44:59 tornado dovecot: doveadm(mozsync): Warning: I/O leak: 0x414190 (line 102, fd 16) Apr 30 19:44:59 tornado dovecot: dsync-local(cisco): Error: remote: doveadm(cisco): Fatal: User doesn't exist Apr 30 19:44:59 tornado dovecot: dsync-local(cisco): Error: read() from worker server failed: EOF Users mozsync and cisco are not valid mail users and it's not appropriate that Dovecot tries to create a Maildir for either of them. The users are system unprivileged users only, and do not ever send or receive mail. And - I/O leak? ;) Also, user cisco is local to one box only, and does not exist (nor does it need to) on the remote host. So any complaints about this user are invalid and dovecot needs to ignore replication for this user anyway. Fourth question, upon starting dovecot again, mail.log then spews several hundred of these messages: Apr 30 19:45:06 tornado dovecot: dsync-local(reuben): Error: msg-get failed: box=Trash uid=114863 guid=1335382569.M98089P29952.tornado,S=6479,W=6625 Before aborting entirely with: Apr 30 19:45:09 tornado dovecot: imap: Server shutting down. in=328 out=2042 It seems to me that a a few of those problems logged could be solved by being able to specify which system users to synchronise, rather than Dovecot making a blind assumption that all users actually have valid Maildirs that need to be created, and all need to be sync'd between two hosts. Subsequent delivery based sync'ing fails silently (pending more investigation) but I'd like to try and fix the above listed problems first before worrying about the later stages of the sync not working. Has anyone else run into these problems or found better ways of making this type of setup all work? Thanks, Reuben

[Dovecot] Sieve doesn't find user scripts
by Jochen Spieker 30 Apr '12

30 Apr '12

Hi, I want to use Sieve filtering with my Dovecot 1.2 installation on Debian squeeze. I have a virtual domain setup using Portgresql. ManageSieve works fine so far, I can edit and activate/deactive scripts (using Thunderbird + Plugin) and they show up in the filesystem where I expect them to be, see below. The problem is that LDA doesn't find the script.

[Dovecot] Refiltering mails without loosing flags
by Dieter Knopf 30 Apr '12

30 Apr '12

Hello, is there a way to refilter all mails in a folder without loosing all flags and moving all messages in a different folder? I have >10k mails in my Inbox and need to create new filterrules from time to time. But there is no way to refilter my inbox without moving. Atm i need to move all mails in a folder like "refilter" and then run getmail/... to refilter the mails. It would be really nice to refilter a existing folder and just move mails with hits in the filter list. Thanks Dieter

[Dovecot] setacl fails - does not find dovecot-acl file
by Michael Stilkerich 29 Apr '12

29 Apr '12

Hi, I'm using dovecot 2.0.13 that ships with Ubuntu 11.10. I tried setting up a shared namespace as documented in the wiki to enable the sharing of a mailbox between two users. I have a Maildir(++) directory for each user. Each user has a system account. The Maildir of each user is owned by the user's system account and group read/writable by the group mail (hence mail_access_groups=mail). Relevant parts of my config: mail_plugins = acl mail_location = maildir:/home/dovecot/%u mail_access_groups = mail namespace { type = private separator = / prefix = inbox = yes hidden = no subscriptions = yes } namespace { type = shared separator = / prefix = shared/%%u/ location = maildir:/home/dovecot/%%u:INDEX=/home/dovecot/%u/shared/%%u subscriptions = no list = children } protocol imap { mail_plugins = $mail_plugins imap_acl } plugin { acl = vfile } plugin { acl_shared_dict = file:/home/dovecot/shared-mailboxes } When I try to create an ACL in a telnet session, the command fails with an internal error. The log shows: dovecot: imap(michael): Error: fstat(/home/dovecot/michael/.test/dovecot-acl.lock) failed: No such file or directory dovecot: imap(michael): Error: file_dotlock_open(/home/dovecot/michael/.test/dovecot-acl) failed: No such file or directory The error occurs whether a (manually created) dovecot-acl file exists or not. The dovecot-acl.lock file is created by not removed afterwards. Subsequent setacl commands will timeout waiting for the lock to be released until I delete it manually. If I create the dovecot-acl file manually and provide access to another user, the getacl command will correctly show the permissions and the other user can access the folder. setacl will still fail to modify the acl file, however (same error). Another thing that irritates me is that dovecot seems to use the dotlock locking method, although I explicitly set lock_method to fcntl (also tried flock, same behavior). I'm not using chroot. I appreciate any help to get this sorted out. Thanks, Michael

[Dovecot] help with AES_DECRYPT and password lookup - mysql password_query
by jeep＠rahul.net 29 Apr '12

29 Apr '12

Hello- Sorry if this is a noob question, but I cant seem to get my password_query to work with dovecot + mysql. Im using 'Password verification by SQL server' at: http://wiki2.dovecot.org/AuthDatabase/SQL trying to modify it to work with my encrypted passwords in the DB. Im using the following which isnt working: password_query = SELECT NULL AS password, \ 'Y' as nopassword, userid AS user \ FROM users WHERE userid='%u' AND AES_DECRYPT(password, 'mykey')=password 1. Is it even possible to do this via 'password_query'? 2. If so, what am I doing wrong? Thanks, Jeff /mf/home/jeep/shell/.signature

[Dovecot] Session IDs
by Timo Sirainen 28 Apr '12

28 Apr '12

v2.1.2 added support for "session IDs", which is a 9 year unique identifier for that specific IMAP/POP3 connection. Initially I thought it would only be useful for tracking connections going through Dovecot proxies to backends (the session ID is forwarded), but then I thought it could be useful for everyone if auth process also logs the session ID. So I thought for v2.1.6 I'd change the defaults: a) Failed login: Apr 28 17:37:23 auth: Debug: client in: AUTH 1 PLAIN service=imap secured session=XtG7KL6+jQB/AAAB lip=127.0.0.1 rip=127.0.0.1 lport=143 rport=42125 resp=<hidden> Apr 28 17:37:23 auth: Debug: passwd-file(foo,127.0.0.1,<XtG7KL6+jQB/AAAB>): lookup: user=foo file=/usr/local/etc/passwd.imap Apr 28 17:37:23 auth: Info: passwd-file(foo,127.0.0.1,<XtG7KL6+jQB/AAAB>): unknown user Apr 28 17:37:25 auth: Debug: client out: FAIL 1 user=foo Apr 28 17:37:50 imap-login: Info: Aborted login (auth failed, 1 attempts in 27 secs): user=<foo>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured, session=<XtG7KL6+jQB/AAAB> b) Successful login: Apr 28 17:38:27 auth: Debug: client in: AUTH 2 PLAIN service=imap secured session=rNuHLL6+jgB/AAAB lip=127.0.0.1 rip=127.0.0.1 lport=143 rport=42126 resp=<hidden> Apr 28 17:38:27 auth: Debug: passwd-file(tss,127.0.0.1,<rNuHLL6+jgB/AAAB>): lookup: user=tss file=/usr/local/etc/passwd.imap Apr 28 17:38:27 auth: Debug: client out: OK 2 user=tss Apr 28 17:38:27 auth: Debug: master in: REQUEST 1375993857 14321 2 0f2f78deedcb7e38a278cf79819360c5 Apr 28 17:38:27 auth: Debug: passwd-file(tss,127.0.0.1,<rNuHLL6+jgB/AAAB>): lookup: user=tss file=/usr/local/etc/passwd.imap Apr 28 17:38:27 auth: Debug: master out: USER 1375993857 tss uid=1000 gid=1000 home=/home/tss Apr 28 17:38:27 imap-login: Info: Login: user=<tss>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=14338, secured, session=<rNuHLL6+jgB/AAAB> .. Apr 28 17:47:15 imap(tss,<rNuHLL6+jgB/AAAB>): Info: Disconnected: Logged out in=8 out=369 The last line requires a modified mail_log_prefix, I wasn't planning on changing its default. I'm mainly wondering: 1) Does this change break someone's auth log line parsing? 2) Does the auth prefix look prettier with or without <> around session id? :) 3) Anything else I should do about this now that I'm changing it anyway?

Hi, I'm sorry to bug you with an not directly dovecot related question, but this is for me right now the place with the best mailsystem admins I know. I'm asked if there is a way to save a copy of all mail we send trough our sendmail server (Red Hat EL 5.x) in and out as an .eml file for further processing by a DMS system. The files should be saved on some network share. Any suggestion are welcome and thanks.

[Dovecot] Permission problems when trying to create new folders with ACL plugin

[Dovecot] v2.1.5 released
by Timo Sirainen 26 Apr '12

26 Apr '12

http://dovecot.org/releases/2.1/dovecot-2.1.5.tar.gz http://dovecot.org/releases/2.1/dovecot-2.1.5.tar.gz.sig A few announcements first: I'm now going to start being more strict about not answering Dovecot questions sent to me privately (especially support requests, but also bug reports, feature requests, etc). Often those questions could be answered by other people in the mailing list as well, so they just waste my time. Even if you're sure that I'm the only person who can possibly answer it, it may be something that others are interested of as well and replying privately denies them the possibility of reading about it. If you really do not want to send something publicly, you still have an option for private communication: just buy one of the Dovecot support packages. This is also the first Dovecot release that has run through automated release testing. I've been planning on doing that for last 5 years at least, and finally it's done. The testing includes running a lot of tests to verify that the IMAP server gives proper responses, stress testing doesn't break it, memory isn't leaked and several other things. The tests are run for many different kinds of configurations. Some bugs show up only for some specific combination of settings, but unfortunately because there's such a large number of them it's impossible to test every combination. So here's another advantage that Dovecot support customers have: they can have their specific configuration included in the automated tests. This release already fixes one bug I found only after testing a customer's config. Oh, and looks like I got accepted as a speaker to LinuxTag 2012. The plan is to talk about some new things in Dovecot and dsync replication (looks like I have to hurry up with the dsync rewrite). And finally, the most important changes since v2.1.4: * IMAP: When neither the session nor the mailbox has modseq tracking enabled, return the mailbox as having NOMODSEQ in SELECT/EXAMINE reply. Old versions in this situation always simply returned HIGHESTMODSEQ as 1, which could have broken some clients. + dict file: Added optional fcntl/flock locking (default is dotlock) + fts-solr: doveadm fts rescan now resets indexes, which allows reindexing mails. (This isn't a full rescan implementation like fts-lucene has.) + doveadm expunge: Added -d parameter to delete mailbox if it's empty after expunging. - IMAP: Several fixes related to mailbox listing in some configs - director: A lot of fixes and performance improvements - v2.1.4 didn't work without a mail home directory set - mbox: Deleting a mailbox didn't delete its index files. - pop3c: TOP command was sent incorrectly - trash plugin didn't work properly - LMTP: Don't add a duplicate Return-Path: header when proxying. - listescape: Don't unescape namespace prefixes.

[Dovecot] LDAP Lookup not returning value in maxStorage
by Bruce, Andrew 26 Apr '12

26 Apr '12

Hi there, We're setting up a Dovecot virtual email setup - we've got everything working perfect with LDAP logins authenticating against AD and so forth, but we're having issues with retrieving the maxStorage value from AD (this is a pre-setup field in AD that we'd like to use to set per user quotas). In our LDAP lookup, we have the maxStorage entry listed under user_attrs for the quota (user_attrs = maxStorage=quota_rule=*:storage=%$M), and in the debug logs, can see it trying to get the entry, but it fails with: Mar 27 13:19:27 auth: Debug: ldap(username(a)site,192.168.1.5): user search: base=dc=site,dc=local scope=subtree filter=(&(objectClass=person)(| (userPrincipalName=username@site) (|(mail=username@site)(samAccountName=username@site)))) fields=maxStorage Mar 27 13:19:27 auth: Debug: ldap(username(a)site,192.168.1.5): no fields returned by the server At this point, we then see the default quota applied. If we change the name of the field from maxStorage to instanceType we see the value show up in the logs and passed through to the quota system and applied successfully: Mar 27 11:09:01 auth: Debug: ldap(username(a)site,192.168.1.5): user search: base=dc=site,dc=local scope=subtree filter=(&(objectClass=person)(| (userPrincipalName=username@site) (|(mail=username@site)(samAccountName=username@site)))) fields=instanceType Mar 27 11:09:01 auth: Debug: ldap(username(a)site,192.168.1.5): result: instanceType(quota_rule=*:storage=%$M)=*:storage=4M Mar 27 11:09:01 auth: Debug: master out: USER 3901227009 username@site quota_rule=*:storage=4M Which seems a bit weird. If we use ldapsearch and pass it the same search string and look for the field maxStorage, we clearly see the field and the value being returned. The result looks the same if we also lookup instanceType. We're using Dovecot 2.0.9. Does anyone have any idea as to why we can't use this field? Thanks, Andrew

Yeah, what he said. Someone helpfully added documentation on how to do this at the end of Dovecot1's wiki (http://wiki.dovecot.org/LDA/Sendmail) which probably should be copied to Dovecot 2's wiki. So that's what I did. Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] dovecot %u variable problem....
by Kris 26 Apr '12

26 Apr '12

Hi guys n gals, im on an ubuntu 11 VPS on linode (dovecot version 2.013). ive spent a lot of time and googling trying to get postfix, dovecot, ssl, saslauthd and mysql to all play nice together and im quite close now but theres something going on i cant quite explain and id really appreciate some help. I have been going for ten hours on this today and it seems in direct conflict with what dovecot themselves say... the problem is a variable in dovecot (%u) which is normally used as a full username in sql query strings (i.e. user@domain) and is simply dropping the domain for some reason... From dovecot docs (http://wiki2.dovecot.org/Variables) The variables that work everywhere are: %u user full username (e.g. user@domain) so i have postfix and stuff set up ok to send at least and i know this because ive tested it by hard-coding the string in the sql query myself with a successful send... but, anyway, the problem with the '%u' variable is it is doing stuff like this: (from mail.log and mysql.log) localhost dovecot: auth: Debug: sql(admin(a)microhard.com,xx.xx.xx.xx): SELECT home,uid,gid FROM users WHERE id = 'admin(a)microhard.com' this was derived from the following query in /etc/dovecot/dovecot-sql.conf.ext user_query = SELECT home,uid,gid FROM users WHERE id = '%u' so no problem there.... but then this happens when i attempt to send mail and this means the user gets rejected because dovecot cant find the user id in the db without the correct string (i.e. user@domain): localhost dovecot: auth: Debug: sql(admin,xx.xx.xx.xx): query: SELECT id as user, crypt as password FROM users WHERE id= 'admin' Query SELECT id as user, crypt as password FROM users WHERE id= 'admin' which is derived from the following query also in /etc/dovecot/dovecot-sql.conf.ext password_query = SELECT id as user, crypt as password FROM users WHERE id= '%u' and to further confuse me, this 'unchangeable' variable sometimes decides to right itself without any obvious reason... localhost dovecot: auth: Debug: sql(admin(a)microhard.com,xx.xx.xx.xx): query: SELECT id as user, crypt as password FROM users WHERE id= 'admin(a)microhard.com' im wondering if its something to do with my client dropping the domain, or whether dovecot has an error, or some other thing ive overlooked... my dovecot.conf looks a lot like this: # 2.0.13: dovecot.conf # OS: Linux 3.0.18-x86_64-linode24 x86_64 Ubuntu 11.10 ext3 first_valid_uid = 5000 last_valid_uid = 5000 login_greeting = I likes my ducks n geese I do. mail_location = maildir:/var/spool/mail/virtual/%u #enables logging all failed authentication attempts. auth_verbose=yes #enables all authentication debug logging (also enables auth_verbose). Passwords are logged as <hidden>. auth_debug=yes #does everything that auth_debug=yes does, but it also removes password hiding. auth_debug_passwords=yes #enables all kinds of mail related debug logging, such as showing where Dovecot is looking for mails. mail_debug=yes #enables logging SSL errors and warnings. Even without this setting if connection is closed because of an SSL error, the error is logged as the disconnection reason (v1.1+). verbose_ssl=yes passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { acl = vfile:/etc/dovecot/acls #quota = maildir:storage=10240:messages=1000 trash = /etc/dovecot/trash.conf } protocols = " imap" service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-master { group = dovecot mode = 0660 user = dovecot } user = dovecot } ssl_ca = /etc/pki/dovecot/certs/ca-bundle.crt ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } userdb { driver = prefetch } userdb { driver = passwd } protocol imap { mail_plugins = quota imap_quota } protocol pop3 { mail_plugins = quota pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } protocol lda { info_log_path = /var/log/dovecot-deliver.log log_path = /var/log/dovecot-deliver.log mail_plugins = quota postmaster_address = admin(a)microhard.com } any help *much* appreciated! cheerz Kris

[Dovecot] dsync: convert only mbox in /var/mail to maildir?
by Jeff Simmons 26 Apr '12

26 Apr '12

I'm migrating an old UW pop server to a new Dovecot server. The old server did not allow mail to be stored on the server, so only mbox files exist in /var/mail, with nothing in /home/$user. I'd like to copy the /var/mail directory over to the new server and then use dsync to convert the mbox files and put them in /home/$user/Maildir, but every permutation of the command line I've tried dies with a variation on can't find/write either /var/mail/mail or /home/$user/mail, seems it won't deal with mbox files without an associated mail directory. Can dsync be used for this kind of conversion, or should I look elsewhere for conversion utilities? Thanks for helping a noob who can't traverse a wiki without leaving a trail of breadcrumbs. -- Jeff Simmons jeff(a)j-simmons.net Simmons Consulting - Network Engineering, Administration, Security

[Dovecot] 2.1.x changes and dsync -- Wiki suggestion
by Jeff Kletsky 25 Apr '12

25 Apr '12

There are a couple things that show up on the Upgrading/2.1 wiki page that would be useful to have on pages describing dsync (Tools/Dsync, Migration/MailFormat, Tools, perhaps others): * dsync was merged into doveadm * You can't dsync 2.0.x to/from 2.1.x That second point is especially "interesting" to me as it seems that Apple MacOS X Server is still on 2.0.16, at least from what I see on opensource.apple.com. I was planning on migrating mail off the current server onto my friend's new MacMini, but I'll have to figure out how to "downgrade" the mail jail to a 2.0 version, it seems. Thanks for all the great work, Jeff

[Dovecot] Reading Mutt mboxes from Thunderbird
by Leonardo M. Ramé 25 Apr '12

25 Apr '12

Hi, I'm a user of Mutt, and before moving to Thunderbird I'm trying to share mboxes between them. To do this, I installed Dovecot to create an IMAP server in my local machine, to serve mutt mboxes to be read by Thunderbird. So far, I can read my inbox from /var/mail/%u, but in mutt, I have many folders in ~/mail, like 2010-mails, 2011-mails, mailing-list-x, mailing-list-y, and so on. How can I configure Dovecot to read them?. In /etc/dovecot/conf.d/10-mail.conf I have this: mail_location = mbox:~/Mail:INBOX=/var/mail/%u I'm using Ubuntu 11.10, and Dovecot 2.0.13.

[Dovecot] How to remove duplicate GUID messages from storage?
by Daniel Parthey 25 Apr '12

25 Apr '12

Hi, I tried to import messages like this: doveadm import -u username(a)example.org mdbox:/mail/dovecot/example.org/username/mail mbox:/root/mail.txt all This seemed to have imported the same messages in the mail storage, as they were already there. And now I have got a lot of duplicates. Then I deleted the mbox:/root/mail mail stuff from "mailboxes" folder and the storage remained, with duplicate GUIDs. The following command doveadm -v force-resync -u username(a)example.org INBOX outputs lots of messages like this one, with different GUID doveadm(username(a)example.org): Error: mdbox /mail/dovecot/example.org/username/mail/storage: Duplicate GUID 0b8a032d66a0924fb42c0000de5f8128 in m.55:45484041 and m.14:52173045 The messages at m.55:45484041 and m.14:52173045 have the same content, since they were seemingly imported from the mail store itself, they are in the storage twice now and require twice as much disk space as before. How can I manually remove these identical, duplicate messages from the storage to save space? Dovecot does not do it automatically. Kind regards, Daniel

[Dovecot] 2.1.5 problem with mail_location

25 Apr '12

I've been advised to set : mail_location = maildir:~/ as the home directory is found through a sql request. this has been working perfectly up to and including 2.1.4 from 2.1.5 however this setting gives cause to a problem : instead of looking in the mail home eg /var/mail/domain/user\@domain/ dovecot is looking for mail in /var/mail/domain/user\@domain/~ the '~' directory is created upon the first request for mail and all future mail transactions in dovecot is done relative to this folder. is this behavior a bug or a feature ??? -- Bjarne D Mathiesen København N ; Danmark ; Europa ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ denne besked er skrevet i et totalt M$-frit miljø MacOS X 10.7.3 Lion ; 2.8GHz Intel Core i7 ; 16GB 1067MHz DDR3

[Dovecot] dsync on large mailbox "fails"
by Jeff Kletsky 25 Apr '12

25 Apr '12

I've been trying to convert an existing set of mbox mail to maildir using dsync, but it seems to fail when it gets to the large boxes. $ dsync -Dv mirror maildir:~/Maildir Everything seems to work reasonably well until the first of the large boxes hits: dsync(jeff): Warning: Maildir /home/jeff/Maildir/.cron.2010-07-10: Synchronization took 1210 seconds (102289 new msgs, 0 flag change attempts, 0 expunge attempts) dsync(jeff): Warning: Transaction log file /home/jeff/Maildir/.cron.2010-07-10/dovecot.index.log was locked for 1210 seconds After this, the doveadm process goes from ~75% of the CPU core utilization to 100% and stays there, even overnight. I've also tried $ dsync -Dv backup maildir:~/Maildir with similar results. While I did see some threads on dsync speed, they seemed to be minutes for a few GB of data, not hours.

[Dovecot] trash plugin bug?
by Cor Bosman 25 Apr '12

25 Apr '12

Hey all, has anyone ever tried turning on the trash plugin when the directory is already over quota? I see some messages being deleted, but it seems it just deletes enough to fit the new email, not enough to go below quota. Example: . getquotaroot "Spam" * QUOTAROOT "Spam" "User quota" "Spam Quota" * QUOTA "User quota" (STORAGE 591036 5242880) * QUOTA "Spam Quota" (STORAGE 21173 20480) I now move a 5K message into this folder, and I see: Apr 23 22:26:43 lmtp1 dovecot: imap(cor): expunge: box=Spam, uid=226337, msgid=<3YVKIIE4II6R0064BA7IM55C2Q4MD01VX12U1I(a)shedevils.com>, size=12984 Apr 23 22:26:43 lmtp1 dovecot: imap(cor): expunge: box=Spam, uid=226338, msgid=<aab6bffa3ad83767d4a7bc571c31449c(a)bonus-news.com>, size=5623 Apr 23 22:26:43 lmtp1 dovecot: imap(cor): save: box=Spam, uid=227759, msgid=<20120423191509.F3B584A355B(a)signal.groundspeak.com>, size=2694 And now: . getquotaroot "Spam" * QUOTAROOT "Spam" "User quota" "Spam Quota" * QUOTA "User quota" (STORAGE 591016 5242880) * QUOTA "Spam Quota" (STORAGE 21158 20480) . OK Getquotaroot completed. This seems like a possible bug. For one, it shouldnt be allowed to actually save a message into that folder, but it does. The email does end up in the Spam folder even though the folder is over quota. And of course it doesnt clear up enough space to have the new email fit, it just deleted enough to match the 5K. Without the trash plugin quota is being properly enforced. Everything works fine if you start out below the quota limit btw. Regards, Cor ps: this is 2.1.4, but with the recent trash and quota patches applied.

Hello, sievec segfaults when it reads a file. I've tried with both the standard and gold linker. I've tried with various sieve files and they all make it crash.

[Dovecot] Dovecot Virtual Users with Users Domain Mapping
by Piotr Maier 24 Apr '12

24 Apr '12

I have successfully compiled, configured and ran Dovecot with virtual users feature. Here's part of my /etc/dovecot.conf configuration file: mail_location = maildir:~/Maildir auth default { mechanisms = plain login userdb passwd-file { args = /home/%d/etc/passwd } passdb passwd-file { args = /home/%d/etc/shadow } socket listen { master { path = /var/run/dovecot/auth-worker mode = 0600 } } } I faced one issue I can't resolve myself. Is there anyway to create users' domains mapping and provide username in mail_location? Example of usersdomains file: domain.com:user1 domain2.org:user3 Examples: 1. currently I have /home/domain.com/user/Maildir 2. I'd like to have /home/SYSTEM_USER/domain.com/user/Maildir Can I achieve this somehow?

[Dovecot] quota not being calculated
by Cor Bosman 23 Apr '12

23 Apr '12

It looks like my quota isnt being calculated properly after I started setting quota to a specific folder. The quota in that folder is always starting out at 0, and only new email is being added to the quota. If I remove the maildirsize file, and recalculate, it still starts at 0. Once email arrives in the folder, it gets added to maildirsize. This is with maildirquota, in perhaps a bit of an exotic config. The idea is to set a specific quota to Spam folder, using the trash plugin to keep it at a certain size. . getquotaroot "Spam" * QUOTAROOT "Spam" "User quota" "Spam quota" * QUOTA "User quota" (STORAGE 40848 1228800) * QUOTA "Spam quota" (STORAGE 0 20000) . OK Getquotaroot completed. Once 1 email gets added: .Spam# cat maildirsize 20480000S 0 0 2017 1 namespace { hidden = no ignore_on_failure = no inbox = yes list = yes location = maildir:%h:INDEX=/var/spool/mail/dovecot-control/indexes/%1u/%2u/%u:CONTROL=/var/spool/mail/dovecot-control/%1u/%2u/%u/INBOX prefix = separator = / subscriptions = yes type = private } namespace spam { hidden = yes ignore_on_failure = no inbox = no list = yes location = maildir:%h/.Spam:INDEX=/var/spool/mail/dovecot-control/indexes/%1u/%2u/%u/.Spam:CONTROL=/var/spool/mail/dovecot-control/%1u/%2u/%u/.Spam prefix = Spam/ separator = / subscriptions = no type = private } plugin { quota = fs:User quota quota2 = maildir:Spam quota:ns=Spam/ quota2_rule = *:storage=20000K sieve = /var/spool/mail/dovecot-control/sieve/%1u/%2u/%u/dovecot.sieve sieve_before = /etc/sieve/before sieve_dir = /var/spool/mail/dovecot-control/sieve/%1u/%2u/%u/scripts trash = /etc/dovecot/conf.d/dovecot-trash.conf.ext } (full config: http://pastebin.com/Mui4X7Zh)

[Dovecot] questions about SPECIAL-USE and virtual
by l.chelchowski＠eurocar.pl 23 Apr '12

23 Apr '12

Hi, I have some questions about Special-Use and virtual namespace: I want to create a virtual namespace with mailboxes: Sent, Unread, Flagged, All. 1. Is it enough to put in the config file: mailbox virtual/Sent { auto = subscribe special_use = \Sent } mailbox virtual/Unread { auto = subscribe special_use = \Unread #Is it correct? } mailbox virtual/Flagged { auto = subscribe special_use = \Flagged } mailbox virtual/All { auto = subscribe special_use = \All } and it would displays mail from every namespace I have subscribed (Shared, Public)? OR I have to make also dovecot-virtual files? 2. In dovecot-virtual file can I put for mailbox virtual/Sent something like: * \Sent 3. Is the http://wiki2.dovecot.org/Plugins/Virtual full documented, if not , where can I find it? 4. Is there a documentation for Special-Use? -- Łukasz

[Dovecot] Bug in HIGHESTMODSEQ when MODSEQ tracking is not enabled for version 2.0.18.
by Glenn Wurster 23 Apr '12

23 Apr '12

Greetings, I'm new to the list. I have encountered what I believe to be a bug in the return of HIGHESTMODSEQ when talking to a IMAP client. HIGHESTMODSEQ does not appear to be incrementing when a new message arrives. The exact steps I took are: 1) Create a new mail account 2) Send a mail to the account, check that you can receive the email. Send a second mail to the account. 3) perform a SELECT on the mailbox from a new session. PMLK4 SELECT INBOX * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 2 EXISTS * 1 RECENT * OK [UNSEEN 1] First unseen. * OK [UIDVALIDITY 1334074920] UIDs valid * OK [UIDNEXT 3] Predicted next UID * OK [HIGHESTMODSEQ 1] Highest PMLK4 OK [READ-WRITE] Select completed. 4) Retrieve the mail. Then perform another SELECT on the mailbox from yet another session. LLEP4 SELECT INBOX * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 2 EXISTS * 0 RECENT * OK [UNSEEN 1] First unseen. * OK [UIDVALIDITY 1334074920] UIDs valid * OK [UIDNEXT 3] Predicted next UID * OK [HIGHESTMODSEQ 1] Highest LLEP4 OK [READ-WRITE] Select completed. 5) Send another mail to the account, and check SELECT again. FKDA4 SELECT INBOX * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 3 EXISTS * 1 RECENT * OK [UNSEEN 1] First unseen. * OK [UIDVALIDITY 1334074920] UIDs valid * OK [UIDNEXT 4] Predicted next UID * OK [HIGHESTMODSEQ 1] Highest FKDA4 OK [READ-WRITE] Select completed. It appears as if HIGHESTMODSEQ is not being updated. I can get HIGHESTMODSEQ to start updating correctly if I send a "UID FETCH 1 MODSEQ" or similar command, which appears to enable MODSEQ tracking at the server (according to the comment around line 173 in file src/lib-index/mail-index-modseq.c), but until that command is sent, MODSEQ tracking is not enabled and hence HIGHESTMODSEQ is always going to return 1. According to RFC4551, the combination of HIGHESTMODSEQ and UIDVALIDITY should be sufficient to determine if the metadata associated with the mailbox has changed, but in this case looking at only those two parameters does not yield sufficient information about changes in the mailbox. The mail client I'm using relies on the combination of HIGHESTMODSEQ and UIDVALIDITY to determine if there are changes in the mailbox, and hence does not see new mail come in. It seems that Dovecot should not be returning HIGHESTMODSEQ in response to a command if MODSEQ tracking is not enabled, but I could be wrong. I've attached my configuration (it's Dovecot 2.0.18 running on Debian Stable). Let me know if you need more information.

[Dovecot] imapc / namespace question
by René Neumann 23 Apr '12

23 Apr '12

Hi, I've got two questions regarding imapc and namespaces: 1) Is there a way of stating, that I only want part of the hierarchy on the end of an imapc connection to be available here? My "problem": On the other end the layout is: INBOX.Shared.{some,nice,folders} If I mirror this into my dovecot hierarchy with prefix "Gemeinsam" I get the following folder structure: Gemeinsam.INBOX.Shared.{some,nice,folders} But I want to ignore the two top-most parts of the hierarchy, i.e. I want it to look: Gemeinsam.{some,nice,folders} Is this possible? I tried with 'location=imapc:INBOX.Shared.' but this did not change anything. 2) "Private" namespaces only make sense, if location contains something user-specific like "%u" or "~". Is this correct? If yes: Is there some other way to make something like an imapc connection only appear for one user, if there is nothing in the location or imapc_user to denote the user it belongs to and hence I cannot use "private"? The only way I see currently is to use "shared" and set up ACLs to forbid all users except one to access the namespace (which gets slightly ugly as I have to use global ACLs, as -- I think -- there is no way to store ACLs for an imapc storage). Thanks, René

This is just one dovecot IMAP client process moaning after another user client process pulled the rug out from under it by modifying the mailbox. I get a few dozen log entries of this sort per week with ~200 IMAP users without shared access. Unless your users actually complain about a problem, I think it's safe to ignore them.

[Dovecot] Correction of home and mail directory config

Hello, after running dovecot for a while, I stumbled accross the warning, not to have mail and home directory settings point to one and same directory. Here is the output of dovecot -n: > dovecot -n # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-686 i686 Debian 6.0.4 ext3 log_timestamp: %Y-%m-%d %H:%M:%S protocols: imaps imap disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login mail_max_userip_connections: 100 mail_privileged_group: mail mail_uid: 5000 mail_gid: 5000 mail_location: maildir:/var/vmail/%d/%n/Maildir mail_full_filesystem_access: yes mbox_write_locks: fcntl dotlock namespace: type: private separator: . inbox: yes list: yes subscriptions: yes lda: auth_socket_path: /var/run/dovecot/auth-master postmaster_address: xxxx(a)xxxx.org mail_plugins: sieve log_path: auth default: mechanisms: plain login passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: static args: uid=5000 gid=5000 home=/var/vmail/%d/%n/Maildir allow_all_users=yes socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: vmail In "args: uid=5000 gid=5000 home=/var/vmail/%d/%n/Maildir allow_all_users=yes" I should delete "Maildir". My question is: What files do I have to copy from /Maildir to the home directory /var/vmail/%d/%n/ ? Are there other side effects, I have to consider? Thank you very much for your help! Stefan

[Dovecot] sieve against ldap in Dovecot 1.2 vacation messeage
by Victor Oñate 22 Apr '12

22 Apr '12

Hi. I need configure "sieve" against ldap this is my file configuration dovecot.conf plugin { quota = dirsize:user sieve_dir = ~/sieve } protocol lda { mail_plugins = sieve } auth default { mechanisms = plain passdb pam { } userdb ldap { args = /etc/dovecot/dovecot-ldap.conf } user = nobody } I dont know what I have to put in dovecot-ldap.conf, ofcourse I have a atribut in LDAP by user with a vacation messeage "I'm out of office, please contact Mr. Black" this is dovecot-ldap.conf hosts = server auth_bind = yes ldap_version = 3 base = dc=dominio,dc=uk deref = never scope = subtree user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid,mail=Maildir,mailQuotaSize=quota_rule=*:storage=%$ user_filter = (&(objectClass=posixAccount)(uid=%u)) The principal idea is keep the control the message by user with LDAP and Dovecot(IMAP). without touching the postfix configuration file is that possible, or am I dreaming. Thanks.. Victor Oñate.

If not, look at this page to configure logging http://wiki.dovecot.org/LDA That's your best chance at finding out the problem. I don't have virtual users, so I can't venture to say whether this is part of the problem. I know I had to fiddle with the mailer flags (you have "DFMPhnu9") to get my setup working, but I don't remember what I did or why. Try adding the "S" flag and see if that helps.

[Dovecot] migrate 15K users to new domain name
by Jan-Frode Myklebust 21 Apr '12

21 Apr '12

I need to migrate 15K users to a new domain name, and plan to use "dsync mirror" in the transition phase. Could someone confirm that this should work: Before giving users access to new-domain do a first sync to get all the stale data over: for user in $old-domain; do dsync mirror $user@old-domain $user@new-domain done Configure sieve vacation filter to forward all messages from $user@old-domain to $user@new-domain, and notify sender of changed address. Give users access to both new-domain and old-domain, and do a final sync. for user in $old-domain; do dsync mirror $user@old-domain $user@new-domain dsync mirror $user@old-domain $user@new-domain # twice in case the first was slow drop all messages for $user@old-domain Leave notice message for $user@old-domain saying he should use new-domain done Wait a few weeks/months, and then drop all users@old-domain. Does this look sensible? -jf

[Dovecot] mbox folders on-disc layout
by John Robinson 20 Apr '12

20 Apr '12

I'd like to change the on-disk layout for my mboxes from being ~/mail/foo/bar to ~/mail/foo.bar so that I can have folders containing both messages and subfolders, without having subfolders beginning with . and then having to do all the other fiddling with locations of index files etc. that goes along with LAYOUT=maildir++, and also leaving the filesystem layout looking sensible so my users see their mailboxes instead of the index and control files. Is this possible or do I need to patch something? (CentOS 6, dovecot 2.0.9) Cheers, John.

[Dovecot] Error in logs indicating broken files
by Steve Campbell 20 Apr '12

20 Apr '12

Still new to dovecot, I'm seeing a couple of errors in my log file indicating corruption of index files. Error: Corrupted index cache file/home/xxxxxx/mail/.imap/sent-mail/dovecot.index.cache: Broken virtual size for mail UID 67: 1 Time(s) Error: FETCH [] for mailbox ~/mail/sent-mail UID 67 got too little data: 6203 vs 7478: 1 Time(s) This account is used by multiple users, but it is not a shared account (haven't set any of those up yet - still new to me), so I would expect corruption possibilities when multiple users modify the account folders in some manner. Until I get some experience under my belt and make this a truly "shared" account, is there any way to resolve the corruption of the files mentioned above? Maybe just delete them? thanks steve campbell

[Dovecot] array code issue ?
by Tim Ruehsen 20 Apr '12

20 Apr '12

Hi, I just took a look into the dovecot 2.1 sources and just saw a possible issue in array.h. This code snippet as an example: #static inline void * #array_get_modifiable_i(struct array *array, unsigned int *count_r) #{ # *count_r = array->buffer->used / array->element_size; # return buffer_get_modifiable_data(array->buffer, NULL); #} array->buffer->used and array->element_size are of type 'size_t' which is 64bit on amd64 and others while 'count_r' is a 32bit value. At least, I see ugly warnings with -Wconversion (which I personally like to use). I know, it is unlikely that 'array->buffer->used / array->element_size' exceeds 32bit range. But then, dovecot's source is so well written, that the above code seems to disturb dovecot's code aesthetics. And who knows... in a few years (when we have THz and TBytes on our desktops) emails (and array sizes) might exceed everything that we think of today. Tim

[Dovecot] old messages being delivered to blackberry
by Luc Belliveau 19 Apr '12

19 Apr '12

Several users are reporting old messages (sometime years old) are being delivered as new on their blackberry devices... I've confirmed that this happens to all blackberry users... I believe the problem is related to this error: Maildir: Expunged message reappeared, giving a new UID In fact, this is the only mail related error message on the server... the mail is stored on a glusterfs share, and I'm using director to prevent simultaneous access... although I wasn't able to get LMTP to work with Director... to simplify things, I've temporarily only enabled 1 dovecot server anyway, to get everything else working first... I'll fiddle with lmtp later... so right now only 1 server is accessing the mailboxes. Delivery is also done from that one server, from postfix. Possibly caused by GlusterFS, the indexes were still getting corrupted, even with only 1 server... so I've moved the indexes to a local directory on each server. I'm no longer getting index related errors... but the expunged error is still occuring... and the error seems to happen a few moments before the BB gets a bunch of messages... so it's very likely related.

[Dovecot] Re-indexing of fts-solr not working
by Joe Beaubien 18 Apr '12

18 Apr '12

Hi, I am currently testing a 2.1 dovecot setup with fts-solr. Search speed is simply amazing. I decided to try to delete and rebuild the solr indexes, but i can't seem to rebuild them thru dovecot. At first, when telnetting to the imap server, the search initially built the index, and then subsequent searches are blazingly fast. 1- I deleted all the solr indexes with the following query: <delete><query>*:*</query></delete> 2- Flag the mailbox to be re-indexed: doveadm force-resync INBOX At this point, it doesn't work. When I telnet into the imap server, the searches always come back empty 3- I also tried a few other commands: doveadm fts rescan, doveadm index INBOX. Still no search results. Nothing seems to be appearing in the logs when I issue all the doveadm commands. What did I miss? Thanks, Joe

[Dovecot] namespace hierarchy
by Tom Fernandes 18 Apr '12

18 Apr '12

Hi, I'm migrating from Courier to Dovecot and would like to keep the original namespace and add two new ones on the new server. There's only one namespace in Courier which is "INBOX." . The seperator is "." In the new server I would like to have 3 namespaces (private, public, shared) and use "/" as separator. Is it possible to keep "INBOX." for private, so that the users mailboxes appear below the Inbox, but have public and shared on the same hierarchy-level like the Inbox? When I set prefix to "INBOX/" for private I get the users mailboxes below the Inbox, like I have it Courier now. But then at least the public, probably also the shared namespace doesn't work any more. I get "unknown subscription namespace" when trying to subscribe to some of the folders. My current configuration is: namespace: type: private separator: / inbox: yes list: yes subscriptions: yes namespace: type: public separator: / prefix: public/ location: maildir:/var/vmail/example.com/public list: yes namespace: type: shared separator: / prefix: shared/%%u/ location: maildir:%%h/Maildir list: yes warm regards, Tom

[Dovecot] Hints for a NFS-Setup
by Patrick Westenberg 18 Apr '12

18 Apr '12

Hi everyone, as I have often trouble with OCFS2 I want to switch to NFS but I'm not sure how to rebuild my cluster with regard to locking and indexing problems. By now my I have a four server configuration (there are another 2 servers for outgoing mail but they can be ignored): MTA(MX10) --(lmtp/socket)--> local dovecot --> iSCSI-LUN with OCFS2 MTA(MX10) --(lmtp/socket)--> local dovecot --> iSCSI-LUN with OCFS2 IMAP-User <--(imap)--> IMAP-Server1 (local dovecot) <--> iSCSI-LUN/OCFS2 IMAP-User <--(imap)--> IMAP-Server2 (local dovecot) <--> iSCSI-LUN/OCFS2 As far as I understood I will get poor performance if I'd just switch from OCFS2 to NFS (while keeping this configuration) with 4 hosts accessing the NFS-share and the index files on it and it is recommended to assign users to a specific host (http://wiki2.dovecot.org/NFS) I'm uncertain what's the meaning of "user" in this context. Is it an IMAP-User or every incoming mail? An IMAP-User assigned to a specific IMAP-Server is ok for me and I could store and profit from local index files. However, I want my incoming mailservers to be equally receiving mails. Both should accept mails for every mailbox but in this case I won't have local indexes. I would appreciate any hints. Patrick

[Dovecot] 487 imap-login processes - is this ok

Hi, recently I checked our mailserver for some more tuning and optimizing and noticed, that currently I do have 487 imap-login processes and I'm asking myself if that's o.k. We do have about 1.000 user in total and not everybody is currently logged in. May be this is o.k. but if not, what might I check? We run the dovecot package provided by redhat EL 5.8 dovecot-1.0.7-7.el5_7.1 Thanks for any comment or suggestion. Regards .

[Dovecot] returning a namespace location from userdb?
by Cor Bosman 18 Apr '12

18 Apr '12

hey all, is it possible to return the location of namespace from the userdb lookup? The code is a bit unclear about it. There seems to be a part of the docs saying: If you want to override settings inside sections, you can separate the section name and key with '/'. For example: namespace default { inbox = yes } The inbox setting can be overridden by returning namespace/default/inbox=no extra field I realize you can set 'location=' in the namespace, but we have mailbox locations that cant be expressed by the normal variable substitution vars in dovecot (dont ask). So we have a userdb that returns the correct mail location. This works fine. But im currently trying to implement a second namespace, and Im having trouble returning a mailbox location for this specific namespace from our userdb. Is this possible? If so, what would the userdb have to return exactly? namespace spam { type = private separator = / inbox = no prefix = Spam/ subscriptions = no list = yes hidden = yes } Regards, Cor

[Dovecot] trash plugin
by Cor Bosman 18 Apr '12

18 Apr '12

The trash plugin docs say: "Normally if a message can't be saved/copied because it would bring user over quota, the save/copy fails with "Quota exceeded" error. The trash plugin can be used to avoid such situations by making Dovecot automatically expunge oldest messages from configured mailboxes until the message can be saved" This leads me to believe that if a message cant be stored, the plugin would avoid returning a quota error, but instead delete/expunge messages until the original message can fit, and then complete the command. But I see something different, at least using the plugin in imap (havent tried it on lmtp). When I drag a message to a folder thats almost full, and the message doesnt fit, I get an actual quota error: 23 uid copy 454343 "Spam" 23 NO [OVERQUOTA] Quota exceeded (mailbox for user is full) After my client sees this error, I see the trash plugin creating space. But then it's too late right? The client already has a visible error. Am I just misunderstanding how the trash plugin is supposed to work? Dovecot 2.1.4, config is on a set of test servers: namespace { type = private separator = / inbox = yes } namespace { type = private separator = / inbox = no prefix = Spam/ location = maildir:/var/spool/mail/%1u/%1.1u/%u/.Spam:INDEX=/var/spool/mail/dovecot-control/indexes/%1u/%2u/%u/.Spam:CONTROL=/var/spool/mail/dovecot-control/%1u/%2u/%u/.Spam subscriptions = no list = yes hidden = yes } plugin { quota = maildir:Spam quota:ns=Spam/ quota_rule = *:storage=5000K } My goal is to create a FIFO spam folder that never returns a quota error, but instead just deletes the oldest emails as new spam comes in. Regards, Cor

Server: Ubuntu 11.10 server with postfix (MTA), dovecot (MDA) Mail client: Outlook Express in Windows XP with IMAP on port 143, SMTP on port 25 When tried to set up a new Outlook Express mail acct, the following error encountered: Your IMAP server wishes to alert you to the following: plaintext authentication not allowed without SSL/TLS, but your client did it anyway.

[Dovecot] vacation plugins for squirrelmail

Thank you folks for your replies. I realised that the dovecot 1.2.9 that I installed via ubuntu synaptic package manager has already come with sieve plugins. After making some modifications on the dovecot.conf file, I went to download and install avelsieve 1.0.1 (stable version) onto the squirrelmail. Then, I run in squirrelmail conf.pl and added the plugin. I logged in and could see "Filter" option right on the top header row. I went to click it and nothing came up.

[Dovecot] POP3 Dovecot Auth CPU usage 75%+

16 Apr '12

Hello all, I hope someone can help me, I have been testing out Dovecot to switch from popa3d which I use at the moment. When I get several users connecting and disconnection multiple times, the Dovecot process with command Auth uses 50-90% of the CPU for the period which they are connecting. I am wondering if there is something that I may have misconfigured, or if there is something that I can change so that this spike doesn't occur. If anyone could shed some light on the issue, I would appreciate it, Kevin /var/mail# dovecot -n # 2.1.4: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 2.6.32-33-generic-pae i686 Ubuntu 10.04.4 LTS ext4 auth_cache_size = 10 M auth_verbose = yes disable_plaintext_auth = no instance_name = Mail Popper 1 listen = 172.20.20.222 login_greeting = Mail Popper 1 Ready mail_location = mbox:/var/empty:INBOX=/var/mail/%u:INDEX=MEMORY mail_privileged_group = mail 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 = shadow } protocols = pop3 service pop3-login { service_count = 0 } ssl = no userdb { driver = passwd } protocol pop3 { pop3_uidl_format = %08Xu%08Xv }

[Dovecot] Better to use a single large storage server or multiple smaller for mdbox?
by Emmanuel Noobadmin 15 Apr '12

I'm trying to improve the setup of our Dovecot/Exim mail servers to handle the increasingly huge accounts (everybody thinks it's like infinitely growing storage like gmail and stores everything forever in their email accounts) by changing from Maildir to mdbox, and to take advantage of offloading older emails to alternative networked storage nodes. The question now is whether having a single large server or will a number of 1U servers with the same total capacity be better? Will be using RAID 1 pairs, likely XFS based on reading Hoeppner's recommendation on this and the mdadm list. Currently, I'm leaning towards multiple small servers because I think it should be better in terms of performance. At the very least even if one node gets jammed up, the rest should still be able serve up the emails for other accounts that is unless Dovecot will get locked up by that jammed transaction. Also, I could possibly arrange them in a sort of network raid 1 to gain redundancy over single machine failure. Would I be correct in these or do actual experiences say otherwise?

[Dovecot] Sieve pipe extension - can it retur something?
by kjonca＠o2.pl 14 Apr '12

14 Apr '12

I have a question about sieve pipe: can it return something to further processing? For example in procmail I can do: --8<---------------cut here---------------start------------->8--- :0 VIRUS=`$CLAMSCAN --mbox --disable-summary --stdout -` --8<---------------cut here---------------end--------------->8--- and then test VIRUS variable. Maybe I missing something, when read http://hg.rename-it.nl/pigeonhole-0.2-sieve-pipe/raw-file/tip/doc/rfc/spec-… KJ -- http://sporothrix.wordpress.com/2011/01/16/usa-sie-krztusza-kto-nastepny/ Gloffing is a state of mine.

[Dovecot] Dovecot 2.1.4 and client certificates
by Бранко Мајић 14 Apr '12

14 Apr '12

Version: 2.1.4 OS: Gentoo stable/amd64 OpenSSL version: 1.0.0h I'm having a slight problem with the client certificates in Dovecot 2.1.4. I've set-up the client certificate verification/authentication, and it seems that Dovecot is choking on the trustchain with CRL's that I'm providing to it (attached to this mail). When I enable the client authentication using certificates, and pick the certificate from my client (I've also tried it out with gnutls-cli as well), I get the following errors in Dovecot's log: imap-login: Info: Invalid certificate: Different CRL scope: /CN=Example Root CA/O=Example Inc./C=RS As per the wiki2 configuration page, I've set up the truststore in the following order (everything PEM-encoded): Example Person CA Certificate Example Person CA CRL Example Root CA Certificate Example Root CA CRL Person CA is the one issuing the end-entity certificates, of course. I'm also attaching the certificate I've used for testing. On additional note, the imap-login process also got stuck writing out the error message to the log file, refusing to die when receiving the SIGTERM (had to send SIGKILL). A similar set-up used to work under Dovecot in Debian Squeeze (version 1.2.15). The same file copied over to Dovecot 2.1.4's configuration won't work. I've compiled Dovecot by hand, and I'm not running it in any kind of chroot (this is a developer set-up so I could add support for rfc822Name username extraction I mentioned a week or so ago without messing around as root).

[Dovecot] Compressed mbox - patch
by kjonca＠o2.pl 14 Apr '12

14 Apr '12

Some time ago I complained about very slow access to compressed mboxes. Unfortunately it looks like that it is very little interest in it, so I have to investigate some things by myself. Firstly: some rationale. Why do I prefer use mbox/maildir over mdbox. Short answer "bus factor" for support mdbox (not only dovecot) Longer answer: if something goes wrong withm maildir/mbox i can use other tools (mutt, or formail or even text editor) and with mdbox ... I am not ISP, I use dovecot as a "gateway" to my (rather huge) mail archive. Most of these mails are rather valuable for me, so I prefer use something "well-known-and-tested". (I can't do like most ISP's do: write in "Terms of Service" that mail can be lost or damaged and we give no warranty :) ) So then: Below my patch. It contains 2 changes: 1. when buffer is compressed, we try to save last marked offset. 2. Increase temporary buffer for decompression. without these changes 1.5 GB of bzip compressed mbox with ~20K messages can't be open in 1.5 day After applying 1. change it can be open in ~1.5 h With both changes it was a few minutes. Maybe it is a good idea to add config parameter to specify size of decompress buffer? Patch is against v2.0.18 -- Gdyby ktoś miał zbędny Toshiba G450 - to chętnie przejmę ;) < asuffield> a workstation is anything you can stick on somebodies desk and con them into using -- in #debian-devel

Just grabbed Dovecot 2.1.2 (which is all properly set up - so I couldn't do anything wrong ;-) and compiled it. Compilation works. Great! The binaries find all their libraries. But two libraries are not quite okay. They don't find their SSL libs: libdovecot-lda.so libdovecot-storage.so Since libdovecot-lda.so doesn't contain the words libssl or libcrypto, I guess that ldd just complains because it uses libdovecot-storage.so. Thus, libdovecot-storage.so is the (only) one left with an incomplete library search path. Luckily, all binaries use some additional libraries which come with a proper library path. So the whole things works, but it's more like some kind of magic. It would be great if libdovecot-storage.so could be fixed as well to make things finally perfect. Thanks for all your effort. (I know this isn't top priority as most people use precompiled stuff and never run into such kind of things.) Greetings, Andreas

[Dovecot] [OT] Outlook identities
by Michael Orlitzky 14 Apr '12

14 Apr '12

Nothing to do with Dovecot, but I figured this is the best place to ask. Do any of the newer versions of Outlook have proper identities support like Thunderbird, mutt, Roundcube, i.e. every other mail client on Earth? We have customers who set up ten different mailboxes for one person because otherwise Outlook won't Do the Right Thing. Is there some way to make it behave like the others? * When sending new mail, you can choose which address to use. * When replying to mail, it sends from the address that the message was sent to by default. * All mail winds up in one inbox. Outlook (2003, 2007) does do this if you set up different mail accounts, but we shouldn't have to do that.

[Dovecot] Unseen messages question
by Antoine Nguyen 14 Apr '12

14 Apr '12

Hi list, this question is related to the IMAP protocol itself, not really to Dovecot. I'm trying to understand what is the more efficient way to maintain the number of unseen messages of the currently selected mailbox. RFC3501 says a client must not issue a STATUS command to the selected mailbox and that information sent by a SELECT is enough. My current idea follows these steps : * Issue a STATUS before the mailbox is selected => I know how many unseen messages it contains * SELECT the mailbox => I got the eventual first unseen message in this mailbox but I don't understand how this info can be useful * Maintain the unseen counter (on client side) according to what the user do * Send a NOOP command every X minutes and look at the RECENT response to see if there are new messages I think it works pretty well when the mailbox is opened only once. Let's imagine this mailbox is opened twice, by different clients. If one client marks a message as \Seen, how can the second client know about this change? Thanks for your help, Antoine Nguyen http://modoboa.org/

[Dovecot] How do I test if the anti spam plugin is working?
by Dr Josef Karthauser 13 Apr '12

13 Apr '12

I've configured the dspam anti spam plugin, but it doesn't appear to be doing anything when I move mail between mailboxes. Can anyone help me determine what's going on? The plugin appears to be loading; at least if I don't define all the required configuration options I get a complaint in the log file. But beyond that I don't see any activity. Here's the config: babel# dovecot --version 2.1.3 The dovecot anti spam plugin config is: protocol imap { mail_plugins = $mail_plugins antispam } and plugin { antispam_debug_target = syslog antispam_verbose_debug = 1 antispam_backend = dspam antispam_signature = X-DSPAM-Signature antispam_signature_missing = error antispam_trash_pattern_ignorecase = trash;Deleted * antispam_spam_pattern = SPAM antispam_dspam_binary = /usr/local/bin/dspam antispam_dspam_args = --deliver=;--user;%n@_%d } I don't even appear to be seeing any log entries from the plugin. I've moving an email from my main mailbox into a mailbox called 'SPAM', which is how I thought that it was supposed to be triggered. Cheers, Joe

[Dovecot] Problems with Apple Mail and attachments
by Helga Mayer 12 Apr '12

12 Apr '12

Hello, has anyone experiences with the Apple mail client, to be precise : Mail 5.2? When I copy a message with an attachment from the inbox to a different folder using 'move' or 'copy' , Apple Mail does not properly display the attachment in the new folder. When I copy the same message using 'archive' the attachment shows up properly. There is no difference on the server side. We are using maildirs. The raw messages in the various folders are identical. Deleting plist on the Mac didn't help. After removing and recreation of the account (client side) the attachments are displayed correctly again. Is this an apple problem or has it got anything to do with dovecot.index.cache ? Kind Regards Helga Mayer

[Dovecot] vacation plugins for squirrelmail
by Daminto Lie 12 Apr '12

12 Apr '12

Hi, I am afraid I have a question to ask of you all. I have just completed setting up a mail server running on Ubuntu Server 10.04. It has postfix, dovecot 1.2.19, LDAP and squirrelmail as the webmail. I have also created virtual users accounts on the system through LDAP. I can send and receive mails which is great. Now, what I am trying to do is to set up a vacation auto-reply on the squirrelmail so that users who are about to go on vacation can set it up themselves. I was looking around for the vacation plugins for dovecot that I can incorporate it into squirrelmail. Any help would be very much appreciated. Thank you

[Dovecot] ldap idle connection timeout in DoveCot 1.0.13?
by Zhou, Yan 11 Apr '12

11 Apr '12

Hi there, We are using DoveCot 1.0.13, it connects to LDAP server for authentication. It seems that DoveCot keeps the idle LDAP connection open. Our firewall is terminating these connections after some time of idle activity (2 hours), then, we run into authentication problem. If we restart either LDAP or DoveCot, then it is fine. Can we set some kind of LDAP idle connection timeout in DoveCot? /etc/dovecot-ldap.conf. I do not see any configuration available for 1.0.13. Another alternative is to set idle connection timeout in LDAP, but we prefer doing that in DoveCot.

[Dovecot] lazy_expunge questions
by James Devine 11 Apr '12

11 Apr '12

I'm messing around with lazy expunge and I just had a couple of questions. If I delete messages or folders with messages, I see them being moved to the expunge namespace, but if I delete an empty folder, all traces of it seem to disappear. Is there a way to move empty folders to the expunge namespace also? My second question is in regards to restoring folders. If I try to execute the imap command 'RENAME EXPUNGED/TEST INBOX/TEST' I get 'NO [CANNOT] Can't rename mailboxes to/from expunge namespace'. Just wondering if this is possible or do I need to recreate the folder and then move messages into it.

[Dovecot] Bug tracker
by Timo Sirainen 11 Apr '12

11 Apr '12

I started thinking that perhaps I should move my TODO list to a bug tracker. But because of reasons I've explained a few times before, I don't want a full blown public bug tracking system. The requirements for it are: * I am the only person who can add new bugs. Everyone else reports bugs/requests to this mailing list as before. (Well, I guess Stephan could use this as well if he wants to.) * Everyone can comment existing bugs. * Dovecot mailing list integration: Commenting a bug sends a mail to the mailing list. Replies to those comments go back to bug tracker (probably based on some [#1234] tag in subject). I would have the option of adding a comment that doesn't go to the mailing list (= adding some internal comment that nobody else cares about). Notifications about new bugs won't go to the mailing list (most likely it was created due to a recent mailing list post). So the main difference to how things work now is that people would be able to easily browse existing bugs and add comments to them. I would add bugs there only when I'm not planning on fixing them within a few days. I wouldn't add each and every feature request there, only the things that I'm actually interested in developing. So the idea would be to actually get the bug tracker emptied at some point, not to be a graveyard of unimportant feature requests that about 1-2 people in the world would want. So, any suggestions for what software could do these things? I think Request Tracker has those features, but it's not really the nicest/prettiest thing.

[Dovecot] Proxy and SSO (single sign-on)
by Miguel Tormo 11 Apr '12

11 Apr '12

Hello, I have a running setup with a dovecot imap4/pop3 proxy to a few dovecot backend servers which actually store the mailboxes. This is running smoothly and allows me to transparently distribute mailboxes. I'm using some "extrafield" configured in the LDAP passdb. However, now I would like to use GSSAPI (preferred) and NTLM for single sign-on. Both are pretty straightforward to configure in a single instance environment, but I don't know if they would work with proxy. For example, with GSSAPI there are two cases: 1) Just use gssapi mechanism, without PAM. Then, it a user presents a ticket the passdb ldap is not used, so the extrafields are never read. 2) Use gssapi and PAM (thus allowing using a kerberos password). But the extrafields feature isn't available with PAM passdb driver, so again the proxy won't work. The case for NTLM would fall into the first case, I think. Am I right regarding this scenario? Is there a way I could make SSO and proxying work? I'm currently using dovecot 2.0.16 (had to patch it to increment LOGIN_MAX_INBUF_SIZE to 4096 for GSSAPI to work, as I read somewhere in this list), but I could upgrade to a newer version if that allows all this to work. Thanks!

[Dovecot] Folder Aliases - Revisited Yet Again
by Daniel L. Miller 11 Apr '12

11 Apr '12

I just did a search through my archives - seems this topic has been requested a few times since my posting two years ago. I asked about a specific implementation - which Mr. Sirainen never commented on. He was probably focused on something more important at the time - like a paying job. So I'll ask again... Calling Timo! If we can't get clients to agree on a "standard" set of folders (probably reasonably safe assumption) and if protocol implementations of variations of "*LIST*" are too far in the future...what about having alternative folder names presented based on login name - maybe by an extension? So where my usual login might be "user(a)domain.com", and that would continue to be supported as the default login, I could now have "user(a)domain.com+thunderbird", "user(a)domain.com+mobile", etc.? And each of those extensions would then have a system-wide map defining folder name relationships, like "Sent=Sent Items". Does this seem doable? -- Daniel

[Dovecot] F5 SLB iRule - POP3 TLS Offload & Add Realm
by Lee Standen 11 Apr '12

11 Apr '12

Hey Guys, I figured someone might have use of this at some point. I've created an iRule for our F5 Load Balancer which performs the following tasks: - Appends STLS to the POP3 Capability list (it does this blindly, so expects the backend POP3 server to not return this) - Watches for the STLS command and initiates SSL negotiation with the client (leaves the connection to the backend POP3 server unencrypted) - Watches for the USER command (login attempt) and appends a realm if the user hasn't supplied one - Stops watching once a successful login occurs It's designed to be attached to port 110 and port 995 at the same time, and will disable SSL if the user is connecting to port 110 until the STLS command is issued. This is a first pass, so there's probably room for improvement, but it does seem to work. This will require LTM v10 (at least), as the SSL::collect command didn't exist prior to that version. Here's the rule: when CLIENT_ACCEPTED { if { [TCP::local_port clientside] == "110" } { # Disable SSL if we're on port 110 (as we're doing TLS Offload) set secure 0 SSL::disable } else { set secure 1 } set realm "mydomain.com" set debug 0 set loggedin 0 } when SERVER_CONNECTED { TCP::collect } when CLIENTSSL_HANDSHAKE { SSL::collect set secure 1 } when CLIENTSSL_DATA { if { $debug } { log local0. "CLIENT DATA: [SSL::payload]" } set lcpayload [string tolower [SSL::payload]] if { $lcpayload starts_with "user" } { scan [SSL::payload] {%s%s} command user set pos [string first $user [SSL::payload] 0] SSL::payload replace $pos [string length $user] "$user@$realm" if { $debug } { log local0. [SSL::payload] } } SSL::release if { $loggedin == 0 } { SSL::collect } } when CLIENT_DATA { if { $debug } { log local0. "CLIENT DATA: [TCP::payload]" } set lcpayload [string tolower [TCP::payload]] if { $lcpayload starts_with "stls" } { TCP::respond "+OK Begin TLS negotiation\r\n" TCP::payload replace 0 [TCP::payload length] "" TCP::release SSL::enable return } elseif { $lcpayload starts_with "user" } { scan [TCP::payload] {%s%s} command user set pos [string first $user [TCP::payload] 0] TCP::payload replace $pos [string length $user] "$user@$realm" if { $debug } { log local0.

Hi, i am playing about mail archive this is what allready works for me require ["variables","date","fileinto","mailbox","envelope","subaddress","regex"]; # Extract date info if currentdate :matches "year" "*" { set "year" "${1}"; } if currentdate :matches "month" "*" { set "month" "${1}"; } if currentdate :matches "day" "*" { set "day" "${1}"; } if envelope :detail :matches "to" "*" { set "to" "${1}"; } if true { fileinto :create "INBOX.${year}.${month}.${day}.${to}"; stop; } but ${to} may have a dot included, foldernames with dot are not allowed in my dove setup yet ( and i dont want to change it ) i am looking for a way ( guess regex ) for replace a dot in string replaced by a space char on the fly -- Best Regards MfG Robert Schetterer Germany/Munich/Bavaria

[Dovecot] Username from rfc822Name subject alternative name
by Бранко Мај ић 10 Apr '12

10 Apr '12

Hello, I'm looking into adding support for extracting the username from client certificate's rfc822Name (from the subjectAltName extension). The question I have is what would be the best approach to do this? Current implementation has a kind of clean code since it just goes through the subject name, extracting the values with X509_NAME_get_text_by_NID (while NID is obtained with OBJ_txt2nid). If I were to add this, it's bound to make the code a little bit more complicated since SAN's can't be retrieved in the same way. So far in terms of options I have, I can see the following: 1. Create a distinct configuration option for the ssl_cert_username_field (i.e. specify something like "sanrfc822Name" to have Dovecot extract the username from the designated alternative name). 2. Make the current code fail-over to rfc822Name SAN if emailAddress is provided for ssl_cert_username (less invasion in code, but less flexibility as well). Any input/recommendation/directioning is welcome. I've wanted to actually first write a patch, and then submit it, but I think it might be better to check what would be preferable by Dovecot maintainers/devs. Best regards -- Branko Majic Jabber: branko(a)majic.rs Please use only Free formats when sending attachments to me.

[Dovecot] Dsync test on 2.1.3
by Jitendra Bhaskar 10 Apr '12

10 Apr '12

Hi, I am using dovecot version 2.1.3 on centos. I tested dsync from my live server to one of backup server. But I got that its working for most of the user and there is problem for few user. Some users got duplicated mail to their mailbox and I saw there is some extra folders i.e Sent Items_* , Draft_* and Trash_* in few users mail box. and I synced only from main server to backup server. I didn't enable mail_plugin in backup server. My configuration for testing of Dsync on master server is as: mail_plugins = $mail_plugins notify replication service aggregator { 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:root@backup_server } #dsync_remote_cmd = ssh -l%{login} %{host} doveadm dsync-server -u%u -l%{lock_timeout} -n%{namespace} dsync_remote_cmd = ssh -l root %{host} doveadm dsync-server -u%{user} -l%{10} -n%{namespace} service doveadm { user = root } And in backup server : service doveadm { user = root } 1. Problem is I am not getting why some user getting lots of duplicate mails. 2. Why duplicate folders like Sent Items_* and Trash_* created for few users 3. I used only one way syncing then why both replicated. Note: i am using root only for testing purpose * Thanks & Regards * *Jitendra Kumar Bhaskar* Cell:- +91 7306311531 +91 8102997821

Hello, My dovecot server (2.0.18 on FreeBSD 9) has multiple interface. I would like to configure the authentication (pop and imap) to append different domain according to the local IP address. I've tested this: local 10.0.0.1 { auth_default_realm = domain1.com } local 10.0.0.2 { auth_default_realm = domain2.com } But it doesn't work. I get this error message: doveconf: Fatal: Error in configuration file /usr/local/etc/dovecot/dovecot.conf line 58: Auth settings not supported inside local/remote blocks: auth_default_realm -- Stephane Locatelli

[Dovecot] 2.0/2.1 - different behavior for LIST-EXTENDED
by Peter Mogensen 10 Apr '12

10 Apr '12

Hi Timo, We are sitting here wondering if this difference in behaviour between dovecot 2.0.17 and 2.1.3 is intended. When you create a folder, subscribe to it and rename it (without changing the subscription) these are the behaviours: For 2.0.17: . list (SUBSCRIBED) "" "*" RETURN (STATUS (MESSAGES)) * LIST (\Subscribed \NonExistent) "." "INBOX.test" For 2.1.3: . list (SUBSCRIBED) "" "*" RETURN (STATUS (MESSAGES)) * LIST (\Subscribed) "." "INBOX.test" * NO Mailbox doesn't exist: test If you don't use rfc5819 the folder will just get silently ignored by dovecot 2.1.x, but if you actually try to get the number of messages you'll get the error. It seems to me from reading rfc5258 that the 2.0.x behaviour is the correct ?? /Peter

[Dovecot] Multiply mailboxes vs one huge
by Alexander Chekalin 10 Apr '12

10 Apr '12

Hello, as I need to store a lot of messages on my IMAP server (order of 900K-1000K; this is an archive for some time, maybe a year or so), I see some "slowness" in dealing with such a huge amount. I mainly need to do searches like "get all messages from user1(a)domain1.com to user2(a)domain2.tld recieved between date1 and date2". So I really interested will it be wise to a) split all messages into several smaller mailboxes (per-month, or per-day, or create 2-level-structure like "month/day/") b) use dbox (vs currently used mbox) storage scheme (I'm afraid of mdbox as I still not sure I'll be able to parse it by scripts later "just in case") Dovecot is the latest one (2.1.3). No compression Dovecot-side, but it mails are in zfs volume with compression on. I ask this mainly due to my not fully understand how Dovecot indexes are working. I also test another approach: to use my own index somewhere outside Dovecot which will store reference between emails and UIDs, and dates and UIDs, so I'll simple query my index for things I need. But then, that's exactly what IMAP index can do, so I simple slow my search down, isn't it? The only reason I think about my own index is I won't use 'all header' as search scope, I need to deal only with From:, To:, Cc:, Bcc: (if any), Recieved (if nowehere else I see the from/to info), and date field(s) - I doubt IMAP will care for that for me. Yours, Alexander

[Dovecot] Director pop-login and imap-login processes exiting on signal 11
by Andy Dills 09 Apr '12

09 Apr '12

We recently upgraded our cluster to 2.1.3, to enable director proxying. Everything appears to be working fine for the most part; the only odd thing is that I'm seeing a lot of entries in the logs like this: Apr 7 02:18:05 mail-out06 dovecot: pop3-login: Fatal: master: service(pop3-login): child 75029 killed with signal 11 (core not dumped - set service pop3-login { drop_priv_before_exec=yes }) This is on the proxy side, not that backend side. When I try to get a dump out of it, and add drop_prive_before_exec and chroot= to the pop3-login statement on the proxy, I keep running into permissions errors with the various service sockets. Any suggestions? Thanks, Andy --- Andy Dills Xecunet, Inc. www.xecu.net 301-682-9972 ---

[Dovecot] Director simplification?
by Timo Sirainen 09 Apr '12

09 Apr '12

An idea I just had: Director basically works by assigning the backend IP address by: ip = vhosts[ md5(username) mod vhosts_count ].ip The rest of director is about what happens when vhosts[] or vhosts_count changes. What about instead doing this on IP address level? ip = ip_pool[ md5(username) mod ip_pool_size ] When a backend dies, you'll reassign the backend's IPs to other backends. Each backend should have many IPs. The main restriction here is that the IP pool cannot change without stopping the entire Dovecot. But if you initially allocate enough IPs, that shouldn't be a problem. And the advantage of this over the current director? To guarantee that one director can't break others, because they don't need to communicate with each others. The disadvantage of course is that it's a little less flexible and requires more planning ahead. The IP address reassignment would also need some distro-specific scripts. This could be implemented as an alternative director-lite or something. The doveadm director status-related commands could still work with it.

[Dovecot] Outlook (2010) -> Dovecot (IMAP) >10x slower with high network load and many folders
by Thomas von Eyben 09 Apr '12

09 Apr '12

Hi, I am seeing a >10x as slow performance when trying to complete a "send/receive" from an Outlook 2010 client to Dovecot via IMAP, but only when the LAN is fully loaded with other traffic, EG file copying. It seems the problem is when outlook is trying to identify folders that have changed since last "send/receive" thus traversing the hierachy. Observations: - Apple's Mail.app does not have problems when exposed to the same environment. - Eliminating Outlook is not an option. - The tests have been performed during the easter vacation, thus almost no other clients are using the network/mailserver. Under normal load there are 2-300 users using the network. Description of the environment: Server sw: Mac OS X Server 10.6.8 running dovecot: 1.1.20apple0.5 (OS = fully updated 10.6.x) Server hw: Xserve Quadcore intel Xeon 2.26 GHz 12 GB RAM - Never having a cpu load > 20%, mail is stored on a Promise vtrack RAID connected via Fibre Channel Client: Windows 7, Outlook 2010 The client have maybe 50 folders (and each folder about a handfull of subfolders) the size of the mailbox is around 3-5 GB. Test results: CLIENT-1 is having the problems when CLIENT-2 is using all the (100Mbps) bandwidth eg. copying files to MAIL-SRV. If I move CLIENT-1 to CLIENT-3 then almost all the delay is gone. NB.: I have not (yet) tested if the problem also exists when CLIENT-2 generates traffic to MAIL-SRV as opposed to OTHER-SRV (but I am expecting the same problems). When dumping the traffic on CLIENT-1 (with Wireshark) one thing is catching my eyes for the 'bad' case: There is a very long delay after each "REQUEST IDLE" until the next "REQUEST DONE" ca. 0,3 seconds. Comparing to the 'good' setup the pause at the same place in the communication is less than 1 ms ! So why this delay? Where/how shall I continue my debugging? - Run dtruss/dtrace scripts on the server? - Get dovecot to output more debug info (I guess it's doing it's best so no problems will be seen there…)? Are there any dovecot configurations that can be altered to workaround [what I think is a limitation in Outlook's IMAP implementation]? The current dovecot configuration is Apple's defaults (+POP3 disabled)) I am seing one warning from dovecotd -n though: - But I see the same warning on a clean installed not-yet-configured OS X Server so I guess it's not 'that' bad: Warning: fd limit 256 is lower than what Dovecot can use under full load (more than 456).

[Dovecot] Setting ACL for master user after login
by PL MB 09 Apr '12

09 Apr '12

Hello, I'd like to log in to normal user accounts as a master user but retain the normal users' ACLs. The Master Users page on the Dovecot 1.x wiki (1) says that I can set the master user's ACLs in a postlogin script. The documentation for master users on the 2.x wiki (2) no longer has any statements about master user ACLs. Has something important in this regard changed? Can I no longer override the ACLs in a postlogin script? Thanks in advance. (1) http://wiki.dovecot.org/Authentication/MasterUsers (2) http://wiki2.dovecot.org/Authentication/MasterUsers

[Dovecot] POP3 dele to Trash?
by Kelsey Cummings 09 Apr '12

09 Apr '12

To simplify recovery of accidentally deleted messages we'd like to send all messages that are deleted by pop clients to their Trash folder. (Which is auto expired already.) This allows a POP client who deletes an important email to restore it themselves by logging into our webmail client and move the lost message from Trash to the Inbox where it would be fetched by their client again. Has anyone already done this? Should this be possible via a plugin? I see the deleted-to-trash imap plugin. We are using Maildir if it makes a difference. -- Kelsey Cummings - kgc(a)corp.sonic.net sonic.net, inc. System Architect 2260 Apollo Way 707.522.1000 Santa Rosa, CA 95407

[Dovecot] Using a namespace for providing access to mail snapshots for user based on-demand restoration of email backups
by Charles Marcus 09 Apr '12

09 Apr '12

Hi all, I'm planning on implementing this in my new upcoming dovecot instance, and would like to hear thoughts on how best to accomplish this. We will be paying Timo's support company to do the work, but obviously, the less work in the form of coding he has to do to get this working (I'm hoping it won't be a lot), the more money it will save us... ;) First - I currently use rsnapshot to backup emails, so that is the use-case I'm most interested in getting working. It is rsync based, and like other rsync based backup programs it uses hardlinks to save storage space - so you can have a *lot* of backups (going back months, or even years), where each snapshot only adds a little more to the total disk space being used. The snapshots are stored with the following filesystem layout: /path/to/snapshotsdir/hourly.0 ... /path/to/snapshotsdir/hourly.4 /path/to/snapshotsdir/daily.0 ... /path/to/snapshotsdir/daily.7 /path/to/snapshotsdir/weekly.0 ... /path/to/snapshotsdir/weekly.4 /path/to/snapshotsdir/monthly.0 ... /path/to/snapshotsdir/monthly.12 /path/to/snapshotsdir/yearly.0 ... /path/to/snapshotsdir/yearly.5 The 'names' (hourly, daily, weekly, monthly, yearly) are arbitrary (this is a bit confusing to people new to rsnapshot), and would *not* be used for displaying the mail folders to the users - it is the Date/Time stamps of each of the snapshot dirs above that would be used to display the folder names under the 'Time Machine' namespace. This is, I imagine, the part that will need some actual coding by Timo to get working - maybe just some new config variables added to the namespace code for mapping the date/time stamps of the directories to user friendly folder names in the namespace. That said, I'd like to design this and have it coded such that it will work with almost any type of backup storage that stores snapshots as date/time stamped directories like this (there must be others, right?). Also, it goes without saying that this code will be (if Timo is ok with it) part of the core dovecot code going forward, so anyone else will be able to benefit from it. What I'm envisioning is something like this... 1. Define a namespace - for this example we'll call it 'Time Machine' 2. Under this namespace, each user will see their, and *only* their snapshots So, each user would see something like this: My Mail Account Inbox Drafts Templates Sent Time Machine (sorted above user created folders if possible) -4/3/12, 8:00am (first subfolder) Inbox Drafts etc... (all other folders and sub-folders shown here) +4/3/12, 12:00pm (first subfolder) etc... Other User Folders ... Or even better, I'm thinking some magical code that can group them by Date, like: -4/3/12 (first subfolder) -8:00am (next sub-folder) Inbox Drafts Etc... (all folders and sub-folders shown here) +12:00pm +4:00pm +8:00pm +4/4/12 etc... Comments? Suggestions? Flames? -- Best regards, Charles

Re: [Dovecot] Using a namespace for providing access to mail snapshots for user based on-demand restoration of email backups

One idea is to take this complexity entirely out of dovecot and create a synthetic filesystem using hard or soft links (as rsnapshot has done) and create your own, with whatever weird and wonderful naming scheme you want. /path/to/TimeMachine/<friendlylabel>/<user> -> /path/to/snapshotsdir/<snaplabel>/<user> namespace { prefix = TimeMachine location = maildir:/path/to/TimeMachine:INDEX=MEMORY ... } This might not be very scalable depending on how big your userbase is. I would probably define memory indices for this namespace, and take the performance hit on the assumption that access will be a once-in-a- while thing. On-disk indices will probably get out of date with each snapshot rollover, if if you have a lot of snapshots/mailboxes, it could consume a non-trivial amount of space without a lot of benefits. Or you could run a cron script to rename or remove old indices, but that seems more trouble than it's worth. One other consideration (at least for me) is if the INBOX and personal mail folders are stored in two separate FS's. It would be nice to fuse the two sets of backups under the same namespace, but I don't know how the namespace prefix matching works and whether you can define hierarchical namespaces like namespace { prefix = backup/inbox location = mbox:/path/to/inbox-snapdir/%u ... } namespace { prefix = backup/mail location = mbox:/path/to/mail-snapdir/%u ... } The above can also be accomplished with a synthetic filesystem.

[Dovecot] 2.1.3: Overly lax FETCH parsing
by Michael M Slusarz 09 Apr '12

09 Apr '12

These commands both work in Dovecot (as of 2.1.3): 1 UID FETCH 1:* () (CHANGEDSINCE 1) * 1 FETCH (UID 30097 MODSEQ (19554)) [...] 1 OK Fetch completed. 2 FETCH 1:* () (CHANGEDSINCE 1) * 2 FETCH (MODSEQ (19554)) [...] 2 OK Fetch completed. However, RFC 3501 indicates that an empty FETCH attribute list is incorrect: fetch = "FETCH" SP sequence-set SP ("ALL" / "FULL" / "FAST" / fetch-att / "(" fetch-att *(SP fetch-att) ")") fetch-att = "ENVELOPE" / "FLAGS" / "INTERNALDATE" / "RFC822" [".HEADER" / ".SIZE" / ".TEXT"] / "BODY" ["STRUCTURE"] / "UID" / "BODY" section ["<" number "." nz-number ">"] / "BODY.PEEK" section ["<" number "." nz-number ">"] In other words, fetch-att is not allowed to be empty. (RFC 4466 does not alter this requirement when using FETCH modifiers). While useful that Dovecot is more liberal about what it receives, 3501 seems pretty clear that incorrect FETCH parameters must return a BAD. I can verify that the above commands fail on Cyrus. I don't disagree that the way Dovecot handles this is correct - or at least is the way that I wish the RFCs were written. Since this seems a bit redundant, but is necessary under the ABNF: 1 UID FETCH 1:* UID (CHANGEDSINCE 1) -or- 1 UID FETCH 1:* (UID) (CHANGEDSINCE 1) michael

[Dovecot] lmtp sometimes fails to deliver a message to all recipients
by Artur Zaprzała 09 Apr '12

09 Apr '12

Dovecot version: 2.1.3 lmtp config: protocol lmtp { mail_plugins = zlib acl sieve } Running strace on lmtp reveals that when lmtp delivers a message to multiple recipients it saves the message to a file in the first mailbox and hard links that file to other mailboxes. But when in the meantime of delivery that file is deleted, lmtp fails to deliver the message to remaining mailboxes. For example a message for 46 recipients is delivered by lmtp to the first 12 only (fortunately postfix retries delivery for remaining recipients) and for the rest lmtp logs the following error messages: lmtp(3344, foo@domain): Error: RU1WMnueeU9QDQABxjIODQ: sieve: msgid=unspecified: failed to store into mailbox 'INBOX': Message was expunged (guid) lmtp(3344, foo@domain): Error: RU1WMnueeU9QDQABxjIODQ: sieve: script /vmail/domain/foo/.dovecot.sieve failed with unsuccessful implicit keep (user logfile /vmail/domain/foo/.dovecot.sieve.log may reveal additional details) I'm seeing this error for about 10 messages per hour.

[Dovecot] dovecot and unison
by FZiegler 05 Apr '12

05 Apr '12

I am successfully using dovecot purely as a personal local mail store on my desktop. (There is only one account, and it's only ever accessed by local mail clients on the machine. The point is to have a common store I can use with any client; plus, I prefer dovecot's Mailbox storage to Thunderbird's mboxes.) Now I'd like if possible, to replicate this setup on my laptop and keep both in sync with unison (http://www.cis.upenn.edu/~bcpierce/unison/) which I am already using to sync much of my home dir about once a day. I found at least one positive message regarding this topic (http://dovecot.org/list/dovecot/2010-April/048092.html) but I feel I could use some more advice. Namely, which of the ancillary files should I be syncing (or perhaps deleting before sync)? In addition to the mails themselves I'm seeing: -rw------- 1 fz 501 13 Apr 1 17:10 dovecot-keywords -rw------- 1 fz 501 2483 Apr 1 17:10 dovecot-uidlist -rw------- 1 fz 501 1040 Mar 29 14:50 dovecot.index -rw------- 1 fz 501 44032 Apr 1 17:10 dovecot.index.cache -rw------- 1 fz 501 9772 Apr 1 17:10 dovecot.index.log and at the top level (in .local/var/Maildir/): -rw------- 1 fz 501 8 Apr 1 17:10 dovecot-uidvalidity -r--r--r-- 1 fz 501 0 Apr 1 17:10 dovecot-uidvalidity.4efb323d -rw------- 1 fz 501 3288 Apr 1 17:10 dovecot.mailbox.log -rw------- 1 fz 501 4104 Mar 28 10:53 dovecot.mailbox.log.2 -rw------- 1 fz 501 5114 Apr 1 17:10 subscriptions In my naive trials I ended up at least once in a situation where Thunderbird would not see some subfolders (even though they were there). That's since fixed but I guess my question is, what's the safe recommended way to not have this happen? Thanks, FZiegler

[Dovecot] Dovecot allows creation of folders outside of a user's directory
by Christoph Bußenius 05 Apr '12

05 Apr '12

Hi, in our dovecot 2.0 setup with shared folders, users can make dovecot create directories outside their mail directory. Which is a bit scary imho. The following command: . create inbox.shared.abc123 or even . create "inbox.shared.strange &ANY- characters" -- even though it will fail with a "permission denied" error -- will create a directory like "/mail/users/strange &ANY- characters". That directory will only contain a subdirectory "Maildir" and therein dovecot-acl-list. I think basically the reason for this behaviour is that Dovecot checks whether the directory has enough ACLs for the user to access it, and auto-creates the directory in the process. Is there way to avoid this auto-creation - or maybe a way to make Dovecot check whether the directory name is an existing username? Here's a config to reproduce this: # 2.0.19: /usr/local/dovecot/etc/dovecot/dovecot.conf # OS: Linux 2.6.32-35-server x86_64 Ubuntu 10.04.4 LTS auth_username_format = %Ln disable_plaintext_auth = no mail_gid = vmail mail_home = /mail/users/%u mail_location = maildir:~/Maildir mail_plugins = " acl" mail_uid = vmail maildir_very_dirty_syncs = yes namespace default { inbox = yes location = prefix = INBOX. separator = . type = private } namespace sharedns { inbox = no list = children location = maildir:/mail/users/%%u/Maildir prefix = INBOX.shared.%%u. separator = . subscriptions = no type = shared } passdb { args = /usr/local/dovecot/etc/dovecot/users driver = passwd-file } plugin { acl = vfile:/usr/local/dovecot/etc/dovecot/global-acls:cache_secs=300 acl_shared_dict = file:/mail/vmail/shared-mailboxes.db } service auth { unix_listener auth-userdb { group = vmail mode = 0660 } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem syslog_facility = local6 userdb { args = /usr/local/dovecot/etc/dovecot/users driver = passwd-file } protocol lmtp { mail_plugins = " sieve" } protocol imap { imap_client_workarounds = tb-extra-mailbox-sep mail_plugins = " acl imap_acl" } Content of the "users" file looks like this: user1:{plain}(hidden):::user1:/mail/users/user1:: user2:{plain}(hidden):::user2:/mail/users/user2:: testuser:{plain}(hidden):::testuser:/mail/users/testuser:: Cheers, Christoph -- Christoph Bußenius Rechnerbetriebsgruppe der Fakultäten Informatik und Mathematik Technische Universität München +49 89-289-18519 <> Raum 00.05.055 <> Boltzmannstr. 3 <> Garching

Hello, After upgrading from 1.2.x to 2.0.x I'm having problems using sent folder in Webmail applications like roundcube mail and squirrelmail. Relevant config dovecot.conf: mail_location = mbox:~:INBOX=/var/mail/%u Different LIST behaviour from rawlog: 1.2.x: with Prefix ~/Mail A002 LIST "" "~/Mail/sent" * LIST (\NoInferiors \UnMarked) "/" "~/Mail/sent" A002 OK List completed. 2.0.x: with Prefix ~/Mail A0003 LIST "" ~/Mail/sent A0003 OK List completed.: Configured prefix for private spaces in roundcube mail is ~/Mail . Roundcube Webmail application checks for existence of the folder but dovecot doesn't return anything in 2.x.latest. Is this by design? Any ideas to fix it by configuration?

I need to authenticate users via LDAP either by mailaddress or login name. In both cases the mailbox location is /src/mail/%d/%n. I can easily deduct that path from the mailaddress, but not so from the login name. Can I get the mail address as part of fetching user_attrs and modify it on the fly? Something along the lines of this: user_attrs = mail:/srv/mail/%d/%n=home,uidNumber=uid,gidNumber=gid Or would I be able to modify this with a post-login script? p@rick -- state of mind () Digitale Kommunikation http://www.state-of-mind.de Franziskanerstraße 15 Telefon +49 89 3090 4664 81669 München Telefax +49 89 3090 4666 Amtsgericht München Partnerschaftsregister PR 563

Hello, I current using dovecot with mdbox and on one account i get this error: doveadm(user@domain): Panic: file mail-index-sync-ext.c: line 209 (sync_ext_reorder): assertion failed: (offset < (uint16_t)-1) doveadm(user@domain): Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(+0x3fd8a) [0x7fae684fdd8a] -> /usr/lib/dovecot/libdovecot.so.0(default_fatal_handler+0x32) [0x7fae684fde72] -> /usr/lib/dovecot/libdovecot.so.0(i_error+0) [0x7fae684d719f] -> /usr/lib/dovecot/libdovecot-storage.so.0(+0x9bdc3) [0x7fae68c1edc3] -> /usr/lib/dovecot/libdovecot-storage.so.0(mail_index_sync_ext_intro+0x1e6) [0x7fae68c1fa76] -> /usr/lib/dovecot/libdovecot-storage.so.0(mail_index_sync_record+0x49f) [0x7fae68c21a3f] -> /usr/lib/dovecot/libdovecot-storage.so.0(mail_index_sync_map+0x234) [0x7fae68c225a4] -> /usr/lib/dovecot/libdovecot-storage.so.0(mail_index_map+0x86) [0x7fae68c13cd6] -> /usr/lib/dovecot/libdovecot-storage.so.0(+0x8b609) [0x7fae68c0e609] -> /usr/lib/dovecot/libdovecot-storage.so.0(mail_index_open+0x210) [0x7fae68c0eaa0] -> /usr/lib/dovecot/libdovecot-storage.so.0(+0x591c6) [0x7fae68bdc1c6] -> /usr/lib/dovecot/libdovecot-storage.so.0(mdbox_map_get_zero_ref_files+0x2d) [0x7fae68bdcd6d] -> /usr/lib/dovecot/libdovecot-storage.so.0(mdbox_purge+0xbc) [0x7fae68bde7ac] -> doveadm() [0x40a135] -> doveadm() [0x40a813] -> doveadm(doveadm_mail_single_user+0x61) [0x40a8d1] -> doveadm() [0x40aafd] -> doveadm(doveadm_mail_try_run+0x141) [0x40af11] -> doveadm(main+0x381) [0x4109c1] -> /lib/libc.so.6(__libc_start_main+0xfd) [0x7fae67d6ec8d] -> doveadm() [0x409ff9] Aborted All doveadm commands fail on thie error, index / force-resync / search / fetch etc. Any help?

[Dovecot] imapsync, namespaces and Dovecot 2.x
by Aleix Dorca 04 Apr '12

04 Apr '12

Hi people, I recently tried to migrate from Exchange using imapsync. It didn't work because it complained that dovecot had no namespace capablity. After looking through Dovecot's config files I found that namespaces could be defined, but if you did not a 'private' default one was created. In the 2.x wiki documentation (http://wiki2.dovecot.org/Migration) it says nothing about Namespaces. I don't know if I have to create one or not. If I add the parameters --sep2 . --prefix2 '' to imapsync then it works fine. I'm proxying using dovecot as frontend and backend, version 2.0.18 (The one that comes with Debian Wheezy). Any thoughts, please? Thanks, Aleix.

[Dovecot] doveadm user -f index
by Micah Anderson 04 Apr '12

04 Apr '12

I've configured my mail_location to have a different location for performance reasons so they aren't in the same location as the mail_location. The 'doveadm user -f home' is useful to find where a user's home directory is for various scripting purposes, but I can't seem to find a way to determine the location of the user's indexes. I can do something with the output of dovecot -a to find the mail_location and then look for a configured INDEX, but then I don't have a good way of translating the %d/%1n/%n type string formatters into their values for a user. thanks for any suggestions! micah --

[Dovecot] Dovecot and scalable database storage
by list＠airstreamcomm.net 04 Apr '12

04 Apr '12

I saw some interesting mails from TImo back in 2009 talking about the idea of using something like Cassandra db or similar as a storage platform for both email and index/logs. I was wondering if this has been discussed since then, and if there are any plans to support something like this in the future? I have been playing with Cassandra and found that their RackAwareStrategy gives you the ability to replicate writes to as many nodes as you would like, but more importantly what nodes and one of those nodes could be defined by what rack it lives in or what data center it lives in. This means multiple sites high available storage clusters, seemingly a system that dovecot could benefit from in terms of performance and redundancy and simplicity. Any takers?

[Dovecot] ldap userdb warning in v2.1.1

Hi, I've upgraded from 2.0.13 to 2.1.1 and when I started the service, I got the following warning: Mar 21 10:07:23 imapserver dovecot: master: Dovecot v2.1.1 starting up (core dumps disabled) Mar 21 10:08:17 imapserverdovecot: auth: Warning: ldap: Ignoring changed user_attrs in /etc/dovecot/dovecot-passdb-ldap.conf, because userdb ldap not used. (If this is intentional, set userdb_warning_disable=yes) I didn't see such warnings in 2.0.13. I guess I should/could remove the "user_attrs" line from dovecot-passdb-ldap.conf because it's not needed?

[Dovecot] dovecot-auth restaring and caching
by Angel L. Mateo 04 Apr '12

04 Apr '12

Hello, I'm trying to configure dovecot (2.0.13) to cache user and pass dbs. This a mail server whose purpose is only to deliver messages through dovecot lda. My users are in a ldap server. So I have configure auth_cache_size (with 20MB) and auth_cache_ttl (with 1 day). I have checked that caching is being done, and it is. If a send a message to a user, dovecot looks for it in my ldap server. If then I send another, then it uses cache information. The problem I'm having is that if I have no activity in the server, dovecot stops its auth process and when another message is received, it restarted it, but with an empty cache. This is the auth log for the first message: Mar 22 10:29:41 lynx10 dovecot: auth: Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth Mar 22 10:29:41 lynx10 dovecot: auth: Debug: Module loaded: /usr/lib/dovecot/modules/auth/libauthdb_ldap.so Mar 22 10:29:41 lynx10 dovecot: auth: Debug: master in: USER#0111#011amateo#011service=lda Mar 22 10:29:41 lynx10 dovecot: auth: Debug: prefetch(amateo): passdb didn't return userdb entries, trying the next userdb Mar 22 10:29:41 lynx10 dovecot: auth: Debug: userdb-cache(amateo): miss Mar 22 10:29:41 lynx10 dovecot: auth: Debug: ldap(amateo): user search: <search base and filter> fields=irisMailbox,homeDirectory,uidNumber,gidNumber Mar 22 10:29:41 lynx10 dovecot: auth: Debug: ldap(amateo): result: uidNumber(uid)=XXXXX gidNumber(gid)=XXX homeDirectory(home)=XXXXXXXXXX Mar 22 10:29:41 lynx10 dovecot: auth: Debug: master out: USER#0111#011amateo#011uid=XXXXXX#011gid=XXX#011home=XXXXXXXXXXXX And this is the second one, just after a few minutes: Mar 22 10:41:03 lynx10 dovecot: auth: Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth Mar 22 10:41:03 lynx10 dovecot: auth: Debug: Module loaded: /usr/lib/dovecot/modules/auth/libauthdb_ldap.so Mar 22 10:41:03 lynx10 dovecot: auth: Debug: master in: USER#0111#011amateo#011service=lda Mar 22 10:41:03 lynx10 dovecot: auth: Debug: prefetch(amateo): passdb didn't return userdb entries, trying the next userdb Mar 22 10:41:03 lynx10 dovecot: auth: Debug: userdb-cache(amateo): miss Mar 22 10:41:03 lynx10 dovecot: auth: Debug: ldap(amateo): user search: <search base and filter> fields=irisMailbox,homeDirectory,uidNumber,gidNumber Mar 22 10:41:03 lynx10 dovecot: auth: Debug: ldap(amateo): result: uidNumber(uid)=XXXXX gidNumber(gid)=XXX homeDirectory(home)=XXXXXXXXXXX Mar 22 10:41:03 lynx10 dovecot: auth: Debug: master out: USER#0111#011amateo#011uid=XXXXX#011gid=XXX#011home=XXXXXXXXXX This is my configuration: root@lynx10:/etc/dovecot/conf.d# doveconf -n # 2.0.13: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-4-amd64 x86_64 Ubuntu 10.04.4 LTS auth_cache_size = 20 M auth_cache_ttl = 1 days auth_debug = yes auth_verbose = yes hostname = lynx10 passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_extensions = +imapflags sieve_max_redirects = 15 } postmaster_address = postmaster(a)um.es protocols = " imap lmtp pop3" service auth { unix_listener auth-userdb { mode = 0666 } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = prefetch } userdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } protocol lmtp { mail_plugins = " sieve" } protocol lda { mail_plugins = " sieve" } Any idea? -- Angel L.

[Dovecot] Is it possible to migrating mail to dovecot using imapc?
by Dr Josef Karthauser 04 Apr '12

04 Apr '12

I'm excited to hear that dovecot now supports imap as a mailbox type. I've got a mailbox over on another imap server, which I want to migrate to dovecot. I was wondering whether I could use 'doveadm backup' to setup a two way synchronisation process between the old imap mailbox and the new dovecot mailbox. That way I can do the migration, and can coordinate the mail clients changing where they pick up their email from later. But, I can't find much documentation on imapc, other than it exists. Is this kind of move possible now? Would someone mind giving me some hints as to how to make it work please? Thanks :), Joe

[Dovecot] dovecot 2.1 breaks FTS + pre-auth?
by dm-list-email-dovecot＠scs.stanford.edu 04 Apr '12

04 Apr '12

Hi. I use dovecot in the simplest possible way, as an IMAP server in pre-auth mode over ssh or just locally over a unix-domain socket (e.g., with offlineimap, which runs much faster using dovecot for the local message store). Ideally I would like to avoid running any extra daemons or setting up anything as root. Until recently, this has worked fine by just setting the CONFIG_FILE environment variable to something in my home directory. Here is my configuration: $ export CONFIG_FILE=$HOME/etc/dovecot.conf $ dovecot -n # 2.1.3: /home/dm/etc/dovecot.conf # OS: Linux 3.2.13-1-ARCH x86_64 mail_location = maildir:~/Mail/inbox mail_plugins = " fts fts_squat" plugin { fts = squat fts_squat = partial=4 full=10 } doveconf: Error: ssl enabled, but ssl_cert not set doveconf: Fatal: Error in configuration file /home/dm/etc/dovecot.conf: ssl enabled, but ssl_cert not set Full text search used to work just fine with this configuration, and still does on a machine I have running dovecot 2.0.13. However, on the machine with 2.1, I get errors about /var/run/dovecot/index not existing. $ printf "a select INBOX\nb search text xyzzy\nc logout\n" \ | /usr/lib/dovecot/imap * PREAUTH [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS SPECIAL-USE] Logged in as dm imap(dm): Error: net_connect_unix(/var/run/dovecot/indexer) failed: No such file or directory ... Needless to say, no dovecot.index.search or dovecot.index.search.uids file is created after this error. While I can't write /var/run/dovecot, this is not a permission issue. For example, adding base_dir=/home/dm (my home directory) to the configuration file yields the same error for /home/dm/indexer. I'm guessing something has changed where imap requires an indexer daemon and doesn't launch it in pre-auth mode any more, but I can't find anything about this in the documentation. In short, if anyone can tell me how to use FTS in conjunction with pre-auth mode or point me to a working example, I would appreciate it.

[Dovecot] Dovecot stones
by Timo Sirainen 03 Apr '12

03 Apr '12

For the last few days I've been thinking about my company and what it really should do, and as much as the current plan seems reasonable, I think in good conscience I really can't help but to bring up an alternative plan: The support for Dovecot is quite good already, but wouldn't it be better if it was GUARANTEED that your email server was ALWAYS working with zero downtime or other problems? After some thinking, planning and consulting with my spiritual guides I realized I really should just go ahead and do it: From now on you can buy blessed Dovecot stones (http://www.dovecot.org/tmp/stone1.jpg) which are guaranteed to keep your email server running. I don't think there's really any further reason for me to provide commercial support. Probably the whole Dovecot mailing list will be pretty much useless after this as well, so I might as well stop posting there. If you have any problems, you'll just buy a Dovecot stone and the problem will go away. If for any reason that doesn't work, it means that your problem is more difficult than most and you need to buy a few more stones. Please remember that each shipment may take up to 3 weeks to reach you, so get your stones early and in sufficient quantities. A small email server will be happy enough with a single small Dovecot stone, but the more users you have the more stones you'll likely need. This is because most people are rather unhappy with their lives, and they project their negative energies towards their surroundings, including their email servers. To overcome this negative energy you need to have a counterbalancing positive energy, which the Dovecot stones will provide you. The Dovecot stones are hand painted from the finest materials available to the sister of the author of Dovecot that she could find in the local shops. Each stone contains such love and dedication towards the well being of Dovecot that you will shed tears when you lay your eyes upon their physical being. The images provided here unfortunately don't do justice to them. http://www.dovecot.org/tmp/stone2.jpg - This is how i keep my home desktop running all day every day. I have NEVER broken a single hard drive in my life. I don't even bother to keep backups, because I KNOW it is useless for me. A small Dovecot stone can be bought for 10 euros, a medium sized stone for 100 euros and a large stone for 500 euros. Each large stone can usually handle around 1000-2000 users before you need to buy more. If you have millions of users we'll need to find you a larger rock from my parents' backyard. There are only a limited number of such rocks available (we disposed of most of them to our neighbors' yards years ago), so their prices need to be negotiated in advance.

[Dovecot] Mail migration troubles
by Spyros Tsiolis 03 Apr '12

03 Apr '12

Hello all, OK, I would really appreciate your help on this. I managed to do a pretty straight-forward and flawless migration on dovecot from one domain to another. However, I have this nagging problem with most of the thunderbird MTAs. When I try to delete some "test" messages I sent to make sure that everything works, it comes back with the following message on the bottom of the Thunderbird window : "The current operation on InBox did not succeed. The mail server for account "Account(a)bloomingdomain.gr" responded [TRYCREATE] mailbox doesn't exist : Trash" Now, I know it has to do something with automatically creating a trash folder. But don't know anything more. Could someone shed some light on this ? Dovecot v1.2.15 AFAIK CentOS 5.5 x86 (32-bit) other stuff On Clients : Thunderbird v11.0.1 (XP Pro / 32-bit) s. ---- "I merely function as a channel that filters music through the chaos of noise" - Vangelis

[Dovecot] imapdir still a configuration option?
by Kurt Mosiejczuk 03 Apr '12

03 Apr '12

I've been looking at moving an old IMAPdir-based solution to dovecot. I came across references that dovecot (to my pleasant surprise) added imapdir support in 1.1. However, in trying 2.0.13 (from an OpenBSD package) things start okay, but I see in the logs: "Initialization failed: Initializing mail storage from mail_location setting failed: Unknown mail storage driver imapdir" Poking around in the sources, I still see lots of references to imapdir, but see very little in the documentation. Is IMAPdir still supported in 2.0.x (or even 2.1.x)? I'd prefer not to have to migrate users via renaming, especially since they like the IMAPdir layout for their own searching. --Kurt

[Dovecot] Connection queue full on dovecot 2.0.13
by Giovanni Mancuso 03 Apr '12

03 Apr '12

Hi, i have a problem with dovecot 2.0.13. I have one dovecot in Front-end that has only: passdb { driver = static args = proxy=y host=10.0.0.6 nopassword=y } In Back-end i have one dovecot that does auth and exports imap/pop3 ports. In dovecot's log of Front-end i see: /Apr 02 14:33:34 imap-login: Info: proxy(//user(a)example.com/ <mailto:amministrazionevendite@pec.gmatica.it>/): started proxying to 10.0.0.6:143: user=<//user(a)example.com/ <mailto:amministrazionevendite@pec.gmatica.it>/>, method=PLAIN, rip=//xx.xx.xx.xx//, lip=xx.xx.xx.xx, TLS Apr 02 14:34:36 imap-login: Info: Disconnected: *Connection queue full *(auth failed, 1 attempts): user=<//user(a)example.com/ <mailto:amministrazionevendite@pec.gmatica.it>/>, method=PLAIN, rip=//xx.xx.xx.xx//, lip=//xx.xx.xx.xx//, TLS/ I see this wiki page: http://wiki2.dovecot.org/LoginProcess but i read: It works by using a number of long running login processes, each handling a number of connections. This loses much of the security benefits of the login process design, because in case of a security hole (in Dovecot or SSL library) the attacker is now able to see other users logging in and steal their passwords, read their mails, etc. Is there another way? Thanks

[Dovecot] Per-user flags/indexes for shared mailboxes
by Timo Sirainen 03 Apr '12

03 Apr '12

The attached patch adds support for doing e.g.: namespace { type = public prefix = Public/ location = mdbox:/var/lib/public/mdbox:INDEXPVT=~/mdbox/public list = yes } So the private flags are stored in indexes under ~/mdbox/public/, while the shared flags are stored under /var/lib/public/mdbox/. The patch currently hardcodes the shared flags as only MAIL_SEEN. I'm not really sure what would be the best place to configure which flags are private. Perhaps a per-namespace default, but how to configure it per-mailbox? Also per-user keywords aren't currently supported. And it's a little bit annoying that each private flag update must increase the shared modseq for the message, but that can't really be helped. (Alternative would be for each user to have their own private modseqs, which could get difficult.) I'll probably commit this to v2.1 after some more testing.

[Dovecot] dsync redesign
by Timo Sirainen 03 Apr '12

03 Apr '12

In case anyone is interested in reading (and maybe helping!) with a dsync redesign that's intended to fix all of its current problems, here are some possibly incoherent ramblings about it: http://dovecot.org/tmp/dsync-redesign.txt and even if you don't understand that, here's another document disguising as an algorithm class problem :) If anyone has thoughts on how to solve it, would be great: http://dovecot.org/tmp/dsync-redesign-problem.txt It only deals with saving new messages, not expunges/flag changes/etc, but those should be much simpler.

[Dovecot] Dovecot 1.2.9. next_uid was lowered
by Müller Lukas 03 Apr '12

03 Apr '12

Hi There A while ago I posted here about a crash of dovecot, that had to do with nfs and was quite certainly due to bad luck. But still one problem persists: We have a Mailbox, that is accessed from multiple users using IMAP. Occasionally all the Emails in the mailbox seem to be missing, when accessing the Mailbox through IMAP, although they're still there on the server. This seems to happen, if the users are accessing the Mailbox on Server1 and at the same time an email gets delivered to the mailbox on server2. Since it happens quite seldom, there must be other conditions or circumstances that have to be met for the problem to occur. Unfortunately I don't know which. Shortly after the mail gets delivered on server2, I get the following errors on server1: mail01 dovecot: IMAP(akzidenz(a)triner.ch): fdatasync(/data/vmail/example.com/user/dovecot-uidlist) failed: Input/output error mail01 dovecot: IMAP(akzidenz(a)triner.ch): /data/vmail/example.com/user/dovecot-uidlist: next_uid was lowered (2143 -> 2142, hdr=2142) The new mail is than missing in the uidlist and as long as no new mail arrives all folders of the mailbox appear to be empty. If a new mail arrives, it will get the uid that should have been given to the pervious mail (the one that caused the error). The previous mail still won't be listed in the uidlist, but everything works as expected.

[Dovecot] setting up ldap for sasl
by jeff donovan 03 Apr '12

03 Apr '12

Greetings im new to the list dovecot --version 2.0.13 ubuntu 11.10 i want to use dovecot to authenticate my ldap users. My local users can authenticate and send email. Using postfix sasl/tls dovecot pam. I have read many docs/tutorials, which all have a plethora of options and information. my file structure is different than most of the documentation. I have ../etc/dovecot.conf which points to. !include_try /usr/share/dovecot/protocols.d/*.protocol !include conf.d/*.conf !include_try local.conf which leads me to /etc/dovecot/conf.d, which is full of config files. All were traditionally located in dovecot.conf in previous versions. im using PAM to authenticate my local system users. I have read that could adjust PAM, to use LDAP. How do I configure dovecot to keep using pam for local users and ldap for remote ? Do i just add the passdb lines dovecot.conf: passdb ldap { args = /etc/dovecot-ldap.conf } userdb prefetch { } # The userdb below is used only by deliver. userdb ldap { args = /etc/dovecot-ldap.conf } dovecot-ldap.conf: pass_attrs = uid=user,userPassword=password, homeDirectory=userdb_home,uidNumber=userdb_uid,gidNumber=userdb_gid # For deliver: user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid any assistance would be helpful. -j

Re: [Dovecot] Mail migration troubles
by Spyros Tsiolis 02 Apr '12

02 Apr '12

I have a suspicion that, as usual, no one is going to answer my message. Because of the fact that this is a call for help and no-one ever bothers, I 'll just have to re-phrase my question : Here's what I found on the dovecot wiki : imapsync Here's an example of how to run imapsync for a single user: imapsync --syncinternaldates \ --host1 192.168.1.57 --authmech1 LOGIN --user1 leah(a)example.com --password1 secret \ --host2 127.0.0.1 --authmech2 LOGIN --user2 leah(a)example.com --password2 secret It is quite easy to script this for a number of users, assuming you have their passwords. Even if you do not, imapsync also supports logging in as an admin user that has the ability to copy message for sub users, and a variety of other authentication options. Is the above what I need if I migrate mailboxes FROM dovecot TO dovecot ? E.g. in my example, I only copy mailboxes from an old "user(a)domainA.gr" to "user(a)domainB.gr". Is the above all I need ? Is there a native dovecot tool for this or should I just use imapsync ?

[Dovecot] Proxying Authentication on both sides
by Andy Dills 30 Mar '12

30 Mar '12

I've recently set up a director proxy environment on my test servers, with the intention of deploying on our cluster soon. One thing I found confusing in the proxying documentation [1] was the first bit about their being two ways to do the authentication...either you have the proxy forward the auth to the real server for authentication, or you have the proxy authenticate it and then login to the real server with a master password. Well, we use /bin/checkpassword authentication which hooks into a variety of subsytems for various specific customer needs, and sometimes we need to know the username AND password of the user in order to determine their home directory information. So, using a master password (which requires the back-end server not getting the user password) is out. However, when we have the front-end server do a static director proxy, the problem is that authentication failures are logged on the back-end server with a source IP of the proxy, and no authentication failure with the client IP address is logged on the proxy. So, fail2ban (which is a MUST these days, at least for us) will not be able to properly filter out the brute force attackers. My solution was an alternative: I authenticate with our /bin/checkpassword on the proxy, which authenticates the user and only at that point returns the proxy=y nopassword=y switch to proxy the connection and forward the authentication. As a result, we get logs on the proxy for failed attempts, and the full username and password is supplied to the back-end server for proper processing. Food for thought in case anybody else is implementing this. Thanks, Andy [1] http://wiki2.dovecot.org/PasswordDatabase/ExtraFields/Proxy --- Andy Dills Xecunet, Inc. www.xecu.net 301-682-9972 ---

[Dovecot] Multiple instances
by Timo Sirainen 30 Mar '12

30 Mar '12

v2.1 now saves the base_dir and instance_name to /var/lib/dovecot/instances when starting up. If you have for example two instances with names "backend" and "proxy", you can then use: doveadm -i proxy proxy list instead of something like: doveadm -c /etc/dovecot-proxy/dovecot.conf proxy list The same -i parameter works for all dovecot programs. I also added a couple of new doveadm commands: # doveadm instance list path name last used running /var/run/dovecot proxy 2012-02-06 21:41:39 yes # doveadm instance remove proxy It would be possible to add commands to start/shutdown some/all instances using doveadm, but is it all that useful? I'd guess people would have their own init.d scripts anyway doing that. Anything else that could be useful related to this?

[Dovecot] IMAP to Maildir Migration preserving UIDs?
by Gedalya 30 Mar '12

30 Mar '12

Hello all, I'm facing the need to migrate from a proprietary IMAP server to Dovecot. The migration must be as smooth and transparent as possible. The mailbox format I would want to use is Maildir++. The storage format used by the current server is unknown, and I don't look forward to trying to reverse-engineer it. This leaves me with the option of reading the mailboxes using IMAP. There are tools like offlineimap or mbsync, and they do store the UID and UIDVALIDITY info. The last piece of the puzzle is a process to properly create the dovecot-uidlist and dovecot-uidvalidity files. So far I wasn't able to find anything on this. Are there any tips? Are there any tools available to do this job, or part of it? In either case I need this done, and I'll have to create whatever I can't find available. If there isn't anything out there that I'm yet to become aware of, then I'm looking at creating something like an offlineimap post-processing routine? Any help would be much appreciated. Gedalya

[Dovecot] Dovecot migration from any IMAP/POP3 server

With the latest hg version / upcoming v2.1.4 you can do a perfect migration to Maildir using imapc/pop3c backends: http://wiki2.dovecot.org/Migration/Dsync The main new feature here is the pop3-migration plugin that matches messages from IMAP and POP3 servers together, so that when dsync needs to request POP3 UIDL for some IMAP message it's actually looked up from the POP3 server.

[Dovecot] newbie: keep getting same emails in mail client
by neuronetv 29 Mar '12

29 Mar '12

dovecot-2.0.9-2.el6_1.1.i686 I've just set up dovecot in centos 6.2 (server install) and finally got it working (kind of). I set up a unix user (not a virtual user) sent a test email to this user but in my mail client I keep getting this test email over and over again. I don't think the fault is with the email client because other emails work fine and never duplicate and I've tweaked the account settings too, so it must be something I've done wrong in the dovecot setup. Here is my dovecot.conf file: # Dovecot configuration file protocols = pop3 imap disable_plaintext_auth = no mail_location = mbox:~/mail:INBOX=/var/spool/mail/unix-username ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem passdb { driver = pam } userdb { driver = passwd } thanks for any pointers. -- View this message in context: http://old.nabble.com/newbie%3A-keep-getting-same-emails-in-mail-client-tp3… Sent from the Dovecot mailing list archive at Nabble.com.

Hey Timo, Splitting this off into a separate thread... On the question of the existing SIS capability for attachments... have you given any thought as to how to solve the problem of restoring from backups when SIS is used? I was planning on using it initially, until I read on list that restoring from (normal disk-to-disk) backups would not work when SIS was enabled - this is obviously a deal breaker for anyone who relies on backups - which I would think would be almost everyone? Or maybe I misunderstood the problem? -- Best regards, Charles

[Dovecot] dsync is SLOW compared to rsync
by Jeff Gustafson 29 Mar '12

29 Mar '12

Hi all, We are currently using snapshots and rsync to backup a large mail server to a backup mail server. I have been looking into using dsync to replace rsync in hopes that it would make backups more efficient. I decided to test the performance using a single mailbox. Unfortunately dsync seems to run much slower than rsync. Rsync was able to sync the mailbox in 2 seconds. dsync took over a minute. The test was run so that the source and destination are on the same filesystem. We would like to using the new replication system, but that doesn't seem likely since the performance of the underlying dsync is so much slower than rsync. Even with the extra work that dsync is doing I can't believe the difference in performance would be that great. I realize that dsync is actively being worked on and I hope bringing attention to performance issue will provoke some ideas on how to improve it. Here is the output of the tests using dovecot 2.1.3: [root@n24 bu]# du -hs /home/10.0.1.101/1009/users/testuser% domain.com/Maildir/ 517M /home/10.0.1.101/1009/users/testuser%domain.com/Maildir/ [root@n24 bu]# time rsync -va /home/10.0.1.101/1009/users/testuser% domain.com/Maildir/ . sending incremental file list Maildir/ Maildir/dovecot-uidlist [ ... deleted cruft ... ] Maildir/cur/1332387577.M381054P27635.n24,S=14215502,W=14448554:2, Maildir/new/ Maildir/tmp/ sent 540927820 bytes received 1222 bytes 216371616.80 bytes/sec total size is 540855755 speedup is 1.00 real 0m2.677s user 0m3.184s sys 0m1.513s [root@n24 bu]# time dsync backup -u testuser(a)domain.com \ mdbox:/home/bu/testuser real 1m9.519s user 1m7.592s sys 0m1.126s [root@n24 bu]# time dsync backup -u testuser(a)domain.com \ sdbox:/home/bu/testuser2 real 1m2.164s user 1m0.882s sys 0m0.993s [root@n24 bu]#

My suspicion is, that it has to do with accessing the same mailbox/mail stored on a NFS-share from two machines at the same time. setup We have to mail servers running, both run a Ubuntu 10.04, Postfix 2.70 and Dovecot 1.2.9. The mailboxes are stored in maildir format on a NFS-Share. In front of those to mail servers we have a load balancer. Unfortunately it can't be set up to use the same server for each domain, but it uses the same server for the same source-ip for at least 1 hour. Here is the output of dovecot -n: # 1.2.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-33-server x86_64 Ubuntu 10.04.3 LTS nfs log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s ssl_ca_file: /etc/ssl/ca-bundle/SSL123_CA_Bundle.pem ssl_cert_file: /etc/ssl/mail.newmedia.ch/mail.newmedia.ch.crt ssl_key_file: /etc/ssl/mail.newmedia.ch/mail.newmedia.ch.key ssl_verify_client_cert: yes disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login mail_max_userip_connections: 25 mail_privileged_group: mail mail_location: maildir:/data/vmail/%d/%n:INDEX=/data/vmail/%d/%n/indexes mmap_disable: yes dotlock_use_excl: no mail_nfs_storage: yes mail_nfs_index: yes mbox_write_locks: fcntl dotlock mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 imap_client_workarounds(default): outlook-idle delay-newmail imap_client_workarounds(imap): outlook-idle delay-newmail imap_client_workarounds(pop3): auth default: passdb: driver: sql args: /etc/dovecot/dovecot-mysql.conf userdb: driver: passwd userdb: driver: sql args: /etc/dovecot/dovecot-mysql.conf plugin: quota: maildir:storage=409600 sieve_global_path: /data/vmail/globalsieverc dict: quotadict: mysql:/etc/dovecot-dict-quota.conf problem the problem happens with a client's mailbox that is used by multiple users. >From time to time he cannot see any Emails in the mailbox, neither with his mail clients (Apple Mail) nor with in the webmail (Roundcube).

Unfortunately I'm not able to reproduce this error. My suspicion/speculation what happens is the following: Multiple users are accessing the Mailbox from their offices (all on the same server), one (or more) uses the Webmail or accesses the Mailbox from a different IP. Somehow this leads to problems with Locks on NFS, which leads to the crash. I have no idea how to solve this problem and any help is greatly appreciated.

A further look into this reveals that the clustered date.saved values are the earliest values for every mailbox in the system. This timestamp is close to the time I was testing "doveadm ... -A", so the likely explanation is that I accidentally deleted/updated these values using some variation of doveadm, even though I remember confining my testing to query/search/fetch. This appears to be a case of PEBKAC. These "wrong" values shouldn't cause problems with expunge queries since they err on the side of safety. Thanks for the insight though.

[Dovecot] doveadm purge on clusterfs
by Jan-Frode Myklebust 28 Mar '12

28 Mar '12

Since doveadm service proxying apparently doesn't work with dovecot v2.0, we need to find a way to safely run doveadm purge on the host the user is logged into. Would it be OK to run purge in the pop/imap postlogin scripts? We already do a conditional: test /var/log/activemailaccounts/imap/$USER -ot /var/log/activemailaccounts/today then touch /var/log/activemailaccounts/imap/$USER fi so adding a: doveadm purge -u $USER in this section would make it run once every day the users that log in. Does that sound like an OK solution? -jf

[Dovecot] Dovecot / IMAP / New Mails are not shown unless you open the folder in Outlook
by stonegate 28 Mar '12

28 Mar '12

Hi, i use dovecot 2.1.3 on a gentoo system. Before i installed my new imap server box, everything worked. Now with Dovecot it does not. Problem: When i receive a new email, it does not appear in my Outlook unless i have the IMAP Inbox Folder open (highlighted selection). Sometimes i have new mail in my inbox for over 15 Minutes and i dont realize it unless i click on the inbox folder. Before that problem occured on my old system ( i think it was dovecot as well ) the inbox folder refreshed automatically and i instantly knew when i had new emails. It was kind of like with my exchange account. Does anyone have a clue what might be wrong ? Since i did not re-install outlook or something it cannot be a client thing since no settings changed on the client side. Maybe i have to do something with dovecots config file? I think it should keep the connection to the server open or something. I´d appreciate any kind of help.

[Dovecot] zlib_save per namespace/mailbox?
by Lutz Preßler 28 Mar '12

28 Mar '12

Hi, the zlib_save question reminds me of a wish: I think it's not possible to set zlib_save parameter per namespace (or even mailbox). Per namespace would be something for the wish list to get rid of the cron job method to compress archival mailboxes. And maybe an option to add a "Z" flag to compressed maildir message files as recommended in the wiki regarding compress crob job. Lutz

[Dovecot] Namespace, prefix questions
by Steve Campbell 28 Mar '12

28 Mar '12

We've got some users who are using Outlook Express version 6. The client allows me to specify the root folder, but not a prefix or namespace. I'm still struggling with some users on our new server that have crazy imap folder layouts, so I've got a few questions. When I specify the root folder, does that bypass any namespace/prefix definitions on the imap server? On some clients, like Thunderbird, I have the option of specifying namespace OR prefix. How do these differ? I thought that the prefix was the "name" of the namespace. It appears that I have to delete and re-create the account on these OE 6 clients to make the list of folders show properly. Does that sound right? This all came about because one of these OE 6 users was not able to use their imap folders (server errors). Turns out it was one of the users that had their folders directly under ~. So I moved them to ~/mail, created a .subscriptions file from their .mailboxlist file and tried everything in the world to get the folders to list properly. Only after specifying the root folder as ~/mail after recreating the account and restarting OE did it show properly and the folders remained listed. My default config has this setup as the "mail_location" parm, but blanks as the root folder don't seem to work in this situation. I'm also wondering where I specify the "list", "hidden" and other parms that are usually set in namespace blocks. dovecot -n # 2.0.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-220.4.1.el6.x86_64 x86_64 CentOS release 6.2 (Final) disable_plaintext_auth = no listen = * mail_location = mbox:~/mail:INBOX=/var/spool/mail/%u mbox_write_locks = fcntl namespace { hidden = yes inbox = yes list = yes location = mbox:~/mail:INBOX=/var/spool/mail/%u prefix = separator = / type = private } namespace { hidden = yes list = no location = mbox:~/mail:INBOX=/var/spool/mail/%u prefix = "#mbox/" separator = / type = private } namespace { hidden = yes list = no location = prefix = mail/ separator = / type = private } namespace { hidden = yes list = yes location = mbox:~/mail:INBOX=/var/spool/mail/%u prefix = ~/mail/ separator = / type = private } namespace { hidden = yes list = no location = prefix = ~%u/mail/ separator = / type = private } passdb { driver = pam } protocols = pop3 imap ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { driver = passwd } protocol pop3 { pop3_uidl_format = %08Xu%08Xv } Thanks steve campbell Thanks steve campbell

[Dovecot] fts-solr not indexing body content
by Bård Johannessen 28 Mar '12

28 Mar '12

This could easily be me missing something, but I can't seem to get the fts-solr plugin to index message bodies. Tcpdump shows me the following being sent from Dovecot to Solr as a messages is indexed: <add><doc><field name="uid">6549</field><field name="box">fde08816e80d6b4f26650000b5f0b4b2</field><field name="user">user</field><field name="id">6549/fde08816e80d6b4f26650000b5f0b4b2/user</field><field name="body"> </field><field name="hdr">Return-path: ... As you can see, the <field name="body"/>-node contains just an empty line. The above is just a snippet to illustrate the problem. A full dump can be found at the following URL: http://db.org/temp/solr.xml.txt Full text search is configures such: plugin { fts = solr fts_solr = break-imap-search url=http://127.0.0.1:8080/solr/ } So; am I missing something, or is this a Dovecot problem? dovecot.conf: http://db.org/temp/dovecot.conf Regards, Bård Johannessen

Hi guys, recently I had some trouble with my ocfs2 cluster and it unmounted itself from /var/mail. Unfortunately I received mails while my mailstore was unmounted and some mails are stored in /var/mail on the hosts local harddisk. Now I need to merge/move these locally stored mails to my ocfs2 mailstore but I don't know how to do this. Regards Patrick

[Dovecot] Need fast Maildir to mdbox conversion
by Jeff Gustafson 28 Mar '12

28 Mar '12

I looked around the 'Net to see if there might be a custom program for offline Maildir to mdbox conversion. So far I haven't turned up anything. The problem for us is that the dsync program simply takes a lot of time to convert mailboxes. I wonder if time could be saved with a program that is optimized to convert mailboxes without the fancy locking that dsync needs to do. Does have (or seen) a tool that could do this? We're hoping that converting away from Maildir will help us speed up the backup processes by reducing the number of files to process. ...Jeff

[Dovecot] Using getmail with sieve
by Orr, Steve 27 Mar '12

27 Mar '12

I'm trying to setup a personal "mailmover" where I use getmail to retrieve remote IMAP server mail and load it into my local Dovecot then filter all email on the Dovecot server side with sieve. (I'm using Dovecot v. 2.0.9 with IMAP/Maildir.) 1) From the docs I gather that Dovecot sieve will not work as mail is loaded by getmail and I need to refilter the email after it has been loaded with getmail, right? 2) In http://wiki2.dovecot.org/HowTo/RefilterMail it says, "This HOWTO helps you create a folder for mail that needs refiltering..." But contrary to the doc I don't see any actual instructions about creating said folder. The HOWTO assumes mail already exists in a folder called "REFILTER' but doesn't say how this folder was populated. "How to?" 3) As a test I manually created the "REFILTER" folder and put my inbox mail in it (with Thunderbird) then following the HOWTO I ran my getmail script and my sieve script performed as expected. 4) How do I automate this? I tried a new getmail script to run against the inbox and tag new email so a subsequent getmail script could move it into the REFILTER folder for later sieve processing. This seems like way too much work. The HOWTO doc seems incomplete or presumes other knowledge, especially for an IMAP server and email sieve nubie. TIA, D.

[Dovecot] Dovecot upgrade from 1.2.x to 2.0.x: roundcube/squirrelmail sent folder doesn't work any more
by Gerhard Wiesinger 27 Mar '12

27 Mar '12

Hello, After upgrading from 1.2.x to 2.0.x I'm having problems using sent folder in Webmail applications like roundcube mail and squirrelmail. Relevant config dovecot.conf: mail_location = mbox:~:INBOX=/var/mail/%u Different LIST behaviour from rawlog: 1.2.x: with Prefix ~/Mail A002 LIST "" "~/Mail/sent" * LIST (\NoInferiors \UnMarked) "/" "~/Mail/sent" A002 OK List completed. 2.0.x: with Prefix ~/Mail A0003 LIST "" ~/Mail/sent A0003 OK List completed.: Configured prefix for private spaces in roundcube mail is ~/Mail . Roundcube Webmail application checks for existence of the folder but dovecot doesn't return anything in 2.x.latest. Is this by design? Any ideas to fix it by configuration? (I tried prefix Mail/ in roundcube mail without success) Thunderbird works well. Thnx. Ciao, Gerhard

[Dovecot] Problem with DOVECOT - long authentication time
by Jacek Kowalski 27 Mar '12

Hi all, I want to start new server with Postfix (I still have qmail ) and I think I have a problem with authentication in dovecot - it takes 3 seconds. Is this normal time? My configuration: Usernames: from MySQL Passwords: from Active Directory dovecot -n # 1.1.20: /etc/dovecot.conf # OS: Linux 2.6.18-274.7.1.el5 i686 CentOS release 5.7 (Final) ext3 log_path: /var/log/dovecot.log protocols: pop3 pop3s imap imaps listen: * ssl_cert_file: /etc/pki/tls/certs/iRedMail_CA.pem ssl_key_file: /etc/pki/tls/private/iRedMail.key login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login mail_uid: 500 mail_gid: 500 mail_location: maildir:/xxx/%u:INDEX=/xxx/%u mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugins(default): quota imap_quota zlib mail_plugins(imap): quota imap_quota zlib mail_plugins(pop3): quota zlib mail_plugin_dir(default): /usr/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 lda: postmaster_address: postmaster(a)domain.com mail_plugins: cmusieve quota log_path: /var/log/sieve.log auth default: mechanisms: plain login default_realm: infor.pl username_format: %Lu debug: yes debug_passwords: yes passdb: driver: pam passdb: driver: sql args: /etc/dovecot-ldap.conf userdb: driver: sql args: /etc/dovecot-mysql.conf socket: type: listen client: path: /var/spool/postfix/dovecot-auth mode: 438 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 438 user: vmail group: vmail plugin: quota_warning: storage=85%% /usr/local/bin/dovecot-quota-warning.sh 85 quota_warning2: storage=90%% /usr/local/bin/dovecot-quota-warning.sh 90 quota_warning3: storage=95%% /usr/local/bin/dovecot-quota-warning.sh 95 quota: maildir quota_rule: *:storage=300M quota_rule2: *:messages=0 expire: Trash 7 Trash/* 7 Junk 30 expire_dict: proxy::expire auth_socket_path: /var/run/dovecot/auth-master sieve: /xxx/sieve/%Ld/%Ln/dovecot.sieve dict: expire: db:/xxx/expire.db grep -v '^ *$#.*$\?$' dovecot-mysql.conf driver = mysql default_pass_scheme = CRYPT connect = host=localhost dbname=xxx user=xxx password=xxx #password_query = SELECT password FROM mailbox WHERE username='%u' AND active='1' user_query = SELECT CONCAT(storagebasedirectory, '/', storagenode, '/', maildir) AS home, CONCAT('*:bytes=', quota*1048576) AS quota_rule FROM mailbox WHERE username='%u' AND active='1' AND enable%Ls%Lc='1' postfix: postfix-2.5.9-5.ired dovecot: dovecot-1.1.20-1_98.el5 mysql: mysql-server-5.0.77-4.el5_6.6 This is not a TCP connection problem, because i have results from tcpdump and wireshark.
