[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.

[Dovecot] Strange behaviour for sieve_before
by Simone Caruso 04 May '12

04 May '12

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. The weird thing is that, with mail_debug=yes the sieve_before script starts working. Any idea? Thanks (my conf attacched, for the new install i used prebuild packages) -- Simone Caruso IT Consultant +39 349 65 90 805

[Dovecot] Sieve script does not run in dovecot 2.0 on squeeze
by Victor Oñate 03 May '12

03 May '12

Hi, I want to use Sieve filtering with my Dovecot 2.0.20 installation on Debian squeeze.

[Dovecot] mdbox corruption
by Daniel L. Miller 02 May '12

02 May '12

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] question dovecot Inheritance global acl vs userfolder acl

Hi Timo my tests resulted in inheritance is given if a userfolder has set some acl to its new created subfolder , which is nice if some userfolder has its acl from global acl there is no inheritance to its new created subfolders, that subfolders will always created with full owner rights i am not really sure if its a good idea to have inheritance from global acl and if its hackabel what is your idea to this ? -- Best Regards MfG Robert Schetterer Germany/Munich/Bavaria

[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] 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] 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).

[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?

[Dovecot] 2.1.x changes and dsync -- Wiki suggestion
by Jeff Kletsky 26 Apr '12

26 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 26 Apr '12

26 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 26 Apr '12

26 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
by postmaster 25 Apr '12

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. There is plenty of space on the drive, and, from what I understand, there is not a file-count limit on FreeBSD's ufs (at least not one that I'm anywhere near) Any suggestions? Thanks!

[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.

I've compiled pigeonhole with -ggdb, but I'm not getting much info Program received signal SIGSEGV, Segmentation fault. 0x0000000800b8e587 in strlen () from /lib/libc.so.7 (gdb) bt full #0 0x0000000800b8e587 in strlen () from /lib/libc.so.7 No symbol table info available. #1 0x0000000800a12e8c in str_append () from /usr/lib/dovecot/libdovecot.so.0 No symbol table info available. #2 0x000000080077f02d in sieve_binary_save () from /usr/lib/dovecot/libdovecot-sieve.so.0 No symbol table info available. #3 0x0000000000605bf0 in environ () No symbol table info available. #4 0x0000000000000000 in ??

[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] 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 21 Apr '12

21 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] Custom LDAP filter for doveadm-mailbox?

Dear Timo, With Dovecot-2.0.16, 'doveadm mailbox list -A' will perform LDAP search with filter "(objectClass=posixAccount)", and get value of attribute 'uid' as mail user. Is it possible to custom the ldap filter and returned attribute name? For example: - LDAP filter: (&(objectClass=mailUser)(accountStatus=active)) - Returned attribute name: mail Did i miss something? Thanks. ---- Zhang Huangbin iRedMail: Open Source Mail Server Solution for Red Hat Enterprise Linux, CentOS, Scientific Linux, Debian, Ubuntu, Mint, Gentoo, openSUSE, FreeBSD: http://www.iredmail.org/

[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. I would like to continue using GlusterFS if possible; I haven't found any indication that it is outright unsupported, as long as I'm using Director... I am using dovecot 2.0.16. Any help would be appreciated! Here is my configuration: # 2.0.16: /etc/dovecot/dovecot.conf # OS: Linux 3.1.9-1.4-desktop i686 openSUSE 12.1 (i586) auth_mechanisms = plain login disable_plaintext_auth = no log_timestamp = "%Y-%m-%d %H:%M:%S " mail_fsync = always mail_location = maildir:~/Maildir:INDEX=/var/indexes/%u mail_nfs_storage = yes mail_privileged_group = vmail managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } plugin { quota = dict:user::file:/var/vmail/%d/%n/.quotausage sieve = /var/vmail/%d/%n/.sieve } postmaster_address = postmaster(a)bigdata.nb.ca service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { group = vmail mode = 0666 user = vmail } user = root } service lmtp { inet_listener lmtp { port = 24 } unix_listener /var/spool/postfix/private/dovecot-lmtp { mode = 0660 user = postfix } } ssl_ca = </etc/postfix/smtpd.bundle ssl_cert = </etc/postfix/smtpd.cert ssl_key = </etc/postfix/smtpd.key userdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } protocol imap { imap_client_workarounds = delay-newmail mail_plugins = quota imap_quota } protocol pop3 { mail_plugins = quota pop3_uidl_format = %08Xu%08Xv } protocol lda { mail_plugins = sieve quota } protocol lmtp { mail_plugins = quota sieve } Luc

[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?

[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%+

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

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] 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

It works with me now that > I tried in a test server with OpenSSL in non-standard dir. Sorry, I didn't know that with "autogen.sh". 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 14 Apr '12

14 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
