[Dovecot] Can't create subfolders when activating namespaces, e.g. private/public
by Torsten Krah 02 Jul '08

02 Jul '08

Hi, i am using hardy dovecot, 1.0.10. If i enable namespaces (the private and a public one) i am unable to create new subfolders in my private namespace, only top level folders works. There is nothing in the log about that error even if i set mail_debug = yes. If i comment out everything (no namespaces at all, implicit private one), it works again. Any hints whats going wrong, why is my client getting the message about not being able to create this subfolder? kinds regards Torsten

[Dovecot] ManageSieve v0.10.3 released for Dovecot 1.1.1
by Stephan Bosch 02 Jul '08

02 Jul '08

Hello Dovecot users, I have formulated a new release that addresses an important ManageSieve compilation issue that arises when compiling with GCC 4.3 (as used by the new Debian Lenny). Change Log v0.10.3 ------------------- * Removed erroneous inline declarations that caused compiler warnings. GCC 4.3 turns out to fail entirely as reported by Joel Johnson. * Fixed auto-detection of Sieve implementation during ./configure. It now produces a proper error when the directory is invalid. Installation ------------ The full installation procedure and other relevant information regarding ManageSieve is available on the Dovecot wiki at: http://wiki.dovecot.org/ManageSieve New release: http://www.rename-it.nl/dovecot/1.1/dovecot-1.1-managesieve-0.10.3.tar.gz http://www.rename-it.nl/dovecot/1.1/dovecot-1.1-managesieve-0.10.3.tar.gz.s… To avoid confusion, I have refreshed the patch as well: http://www.rename-it.nl/dovecot/1.1/dovecot-1.1.1-managesieve-0.10.3.diff.gz http://www.rename-it.nl/dovecot/1.1/dovecot-1.1.1-managesieve-0.10.3.diff.g… My public key (id: 3DFBB4F4) can be found at wwwkeys.pgp.net.

[Dovecot] "select NULL as password..." failing after upgrade to dovecot-1.1
by Sergey Ivanov 02 Jul '08

02 Jul '08

Hi, I've upgraded mail server to dovecot-1.1, on solaris-10 with mysql user database. I used sql query "SELECT NULL as password, login as user, concat('/mail/var/dovecot/',login) AS userdb_home, 501 AS userdb_uid, 501 AS userdb_gid FROM users WHERE login='%n' AND password=old_password('%w')" with dovecot-1.0.15 and it worked perfectly. But since upgrade the server can not authenticate any users, complaining in info_log: "Empty password returned without no_password". How to set up such things in dovecot-1.1? Is it possible? -- Sergey Ivanov.

[Dovecot] Users can't delete an email (Totally Random effect)
by Jesse C. Smillie 02 Jul '08

02 Jul '08

Hello all... Found a weird one here. I tried to search the web but I'm not having luck so I thought I'd hit the mailing list. We have noticed off and on all school year that every so often a user gets an email that they just can't delete using Thunderbird or Outlook over IMAP (we do not support Pop3 anymore.) Essentially the user clicks the email and takes it to the trash. When they empty the trash the email appears again in their inbox as if it was new! Up until this point I would just tell people to login to Usermin which is still set to access the email natively through the maildir format and delete it that way. What we have found out is that emails which have their info fields repeated twice are emails which can't be deleted. So for example: root@gator:/home/somedude# find ./ -iname '*,*,*' ./Maildir/cur/1208807796.29873_0.gator:2,Sb:2,S ./Maildir/cur/1205162628.14926_0.gator:2,Sb:2,S ./Maildir/cur/1206557108.6542_0.gator:2,Sb:2,STb ./Maildir/cur/1204054624.5835_0.gator:2,Sa:2,S ./Maildir/cur/1208957483.28799_0.gator:2,RSb:2,RSTb ./Maildir/cur/1208803572.18922_0.gator:2,Sb:2,S ./Maildir/cur/1209482166.31816_0.gator:2,Sb:2,S ./Maildir/cur/1212778554.27192_0.gator:2,Sa:2,S ./Maildir/cur/1210613916.23757_0.gator:2,Sb:2,S ./Maildir/cur/1210277191.15311_0.gator:2,Sa:2,S ./Maildir/cur/1204813078.31520_0.gator:2,Sa:2,S ./Maildir/cur/1207318169.27142_0.gator:2,Sb:2,STb ./Maildir/cur/1206732320.12478_0.gator:2,RSb:2,RSTb ./Maildir/cur/1210788980.15319_0.gator:2,RSb:2,S ./Maildir/cur/1205432415.9316_0.gator:2,RSb:2,S ./Maildir/cur/1204135464.22085_0.gator:2,Sb:2,S ./Maildir/cur/1207161276.31798_0.gator:2,Sb:2,S ./Maildir/cur/1203969436.24684_0.gator:2,Sa:2,S ./Maildir/cur/1207753826.6079_0.gator:2,Sa:2,RSa ./Maildir/cur/1207832151.6749_0.gator:2,Sb:2,S ./Maildir/cur/1212082057.25882_0.gator:2,Sa:2,S ./Maildir/cur/1205856514.5523_0.gator:2,Sb:2,S ./Maildir/cur/1207072150.20246_0.gator:2,RSab:2,S ./Maildir/cur/1208800746.30992_0.gator:2,Sb:2,S ./Maildir/cur/1205353851.26747_0.gator:2,Sb:2,S All of these emails will not be deletable by the imap client. They will do the thing I described above. If I remove one of the info fields they can be deleted. We also found if we create a fake email and name it "test:2,ae:2,Sae" it too will have the nondelete problem. Unfortunately I don't know how or why these emails are created. As far as the vitals go: We are running Dovecot 1.0.14 now, but I have been able to observe this problem through a few of the last versions. The server runs Slamd 64 10.2 (Opteron 64 CPUs) and all of the home directories are on a ReiserFS formatted Volume Anything else I can tell you please let me know and of course any info anybody can tell me about how to make this weirdness go away would be greatly appreciated. Thanks. -- -Jesse C. Smillie "Insert inspirational or witty comment here...."

[Dovecot] courier IMAP to dovecot migration: folders not showing up
by Jacob Yocom-Piatt 01 Jul '08

01 Jul '08

i have been running postfix + courier-imap + cyrus sasl for several years and have some prior experience with dovecot + postfix and had no problems. now that i'm trying to convert an existing courier-imap configuration to dovecot and all the various parts work together (e.g. mail delivery and dovecot sasl), i cannot get the folder subscription issue sorted. the machine is running netbsd 4.1 + postfix 2.5.1 + dovecot 1.0.13. searching for a bit yields the following useful links http://wiki.dovecot.org/Migration/Courier http://wiki.dovecot.org/Migration http://marc.info/?l=dovecot&m=120592911416484&w=2 i have downloaded and run the courier-dovecot-migrate.pl script and that does not do the trick, nor does following it up with the suggested changes in the private namespace. an example of one of the maildirs i have at hand is mail# ls -al total 1580 drwx------ 71 vmail users 2560 Jun 27 13:47 . drwx------ 24 vmail users 512 May 28 14:10 .. drwx------ 6 vmail users 512 Jun 27 12:10 .Drafts drwx------ 5 vmail users 512 Jun 27 13:17 .INBOX.Trash drwx------ 6 vmail users 512 Jun 27 12:45 .RT drwx------ 6 vmail users 512 Jun 27 12:50 .Sent drwx------ 6 vmail users 512 Jun 27 12:46 .Trash drwx------ 6 vmail users 512 Jun 27 12:45 .Trash.bro drwx------ 6 vmail users 512 Jun 27 12:45 .associates .... and the subscriptions file, after courier-dovecot-migrate.pl runs is Trash Sent Drafts associates .... based on the folder subscriptions, i have attempted to move the folders preceded by a '.' to the same name without a '.'. this does not fix the problem either. any clues on how to fix this issue would be welcome. cheers, jake

[Dovecot] Poor pop3 over nfs performance
by Mark Zealey 01 Jul '08

01 Jul '08

Hi, About a week ago I upgraded our reasonably heavily loaded mail servers from a pretty recent courier version to dovecot-1.1rc10. IMAP performance on dovecot is amazing, however POP3 performance is worse than courier :-( I have uploaded some munin graphs taken today to http://linweb.atlas.pipex.net/dovecot/; the dovecot server is handling about 2000 pop logins/sec and 300 imap sessions (but these are negligible in terms of nfs ops). The courier server is handling a similar number of pop logins/sec but no imap (slightly less traffic overall but a similar number of logins). As you can see, dovecot seems to issue an awful lot more read requests than courier. The big spike at 10am is where I tried setting the :INDEX=MEMORY flag on dovecot as I assumed that's what courier is doing. I've also attached graphs of the relative network usage - as you can see, dovecot is using up to 100mbps whereas courier is using less than 10mbps; I believe this is due to the read. I initially assumed this high read load was due to courier building up its index files, but this has now been happening for about a week with little variation. The servers are both centos 5.0 (perhaps 5.1 actually, but with the latest centosplus kernel which fixes the nfs lookup bug in the standard kernels); and are not running any other nfs programs. The NFS server is a high performance NAS unit - no issues there. We're only using Maildirs; relevant config options are: mmap_disable: yes dotlock_use_excl: no mail_nfs_storage: yes mail_nfs_index: yes lock_method: dotlock maildir_copy_preserve_filename: yes Thanks, Mark

[Dovecot] Maildir and Invalid data in file
by Patryk 01 Jul '08

01 Jul '08

Hi Timo, Regarding our conversation in IRC, I'm attaching the uidlist and copying in the original message just in case. I'm using dovecot version 1.0.13 on reiserfs on hardware RAID-0, but I'm getting the following error in the logs every time one user tries to access his old mails in the .Sent directory: dovecot: 2008-06-23 15:09:46 Error: IMAP(marek.chajecki): Invalid data in file /var/mail/Maildir/marek.chajecki/.Sent/dovecot-uidlist As a result he fails to get access to the emails in this folder. I've googled a bit and read that deleting the uidlist makes dovecot recreate it, but after some time the same thing happens. It's a new hard drive, so I don't think this is a hard drive fault. Some additional info: this server is being used by about 200 users who get about 100 emails daily each one of them. Config: root@warsaw Maildir # dovecot -n # 1.0.13: /etc/dovecot/dovecot.conf log_path: /var/log/dovecot.log info_log_path: /var/log/dovecot.log log_timestamp: %Y-%m-%d %H:%M:%S ssl_listen: * login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login login_process_per_connection: no login_processes_count: 15 login_max_processes_count: 512 max_mail_processes: 4096 mail_privileged_group: mail mail_location: maildir:/var/mail/Maildir/%u maildir_copy_with_hardlinks: yes auth default: worker_max_count: 100 passdb: driver: pam args: cache_key=%u dovecot userdb: driver: passwd Any help will be appreciated! -- Regards, Patryk Rzadzinski

Hi, I would like to use Dovecot as IMAP Server in order to Develope a Squirrel Webmail. I have a problem with the Dovecot configuration; I have my Postfix server in the host: 192.168.100.100, and I have installed Dovecot in the host: 192.168.1.253. Everything goes right, but I can't see any mail that I had received in my mailbox. How can I configure the dovecot.conf in order to use an mbox placed in a different host?? Thanks.

[Dovecot] Global FTS index?
by Patrick Nagel 30 Jun '08

30 Jun '08

Hi, I tried the FTS (and FTS Squat) plugin today, and it works as advertised. But: On my 13000 folders with 160000 mails maildir I use for testing, the speed increase is not as big as one would wish (it still takes several minutes to complete a search). Is my assumption correct, that there is no way to do a search over a big IMAP folder hierarchy in a reasonable amount of time, because each folder has to be 'selected', and only one folder can be selected at once?

[Dovecot] Quota Check: fs with multiple "noenforcing" mount point
by Grandy Fu 30 Jun '08

30 Jun '08

Hi, It seems my previous mail has been lost, I apologize if this is a duplicate. I am using Dovecot 1.1.1 with user's INBOX in /var/mail and other folders in their home directories. I have setup file system quota on /var/mail to limit their usage. I would like dovecot to display such information in IMAP client and ignore all others. OS: Solaris 10 Dovecot version : 1.1.1 file system of /var/mail : NFS from Solaris file system of /home : other NFS server that not support rquotad. Here is my setting that works: ---------------------------- plugin { quota = fs:INBOX:mount=/var/mail quota2 = fs:home:noenforcing:mount=/home/h1 } ------------------------------------------ Unfortunately, I have many different mount points for different users, so I changed my settings to: --------------------------- plugin { quota = fs:INBOX:mount=/var/mail quota2 = fs:home:noenforcing:mount=/home/h1 quota3 = fs:home:noenforcing:mount=/home/h2 quota4 = fs:home:noenforcing:mount=/home/h3 } ---------------------------------------------- The result is... Devocolt is not able to get quota information anymore. Any suggestions?

[Dovecot] quota_warning script
by Nicolas Letellier 29 Jun '08

Hello. I'm reading http://wiki.dovecot.org/Quota/1.1 one last time before my upgrade, and I have a question about quota_warning option. Which type of script must we use for this example: quota_warning = storage=95%% /usr/local/bin/quota-warning.sh 95 What the script must doing? It sends an email? It deletes some emails? Thanks! -- -Nicolas.

[Dovecot] Dovecot corrupted index cache
by Michael D. Godfrey 28 Jun '08

28 Jun '08

System: Linux 2.6.25.6-55.fc9.x86_64 #1 SMP Tue Jun 10 16:05:21 EDT 2008 x86_64 x86_64 x86_64 GNU/Linux Dovecot: dovecot-1.0.14-8.fc9.x86_64 We have used Dovecot for several years. The error message below appears in the system log quite frequently. I have run a test which shows that this message is due to 2 or more users accessing the same mail (i.e connecting using the same userid). This happens for various reasons including the fact that some users have their client machine set up (typically using Thunderbird) with more than one account within a single Thunderbird configuration. Thus, more than one person may be reading or sending mail from a single Dovecot account. The Dovecot error is: Dovecot disconnects: Inactivity: 13 Time(s) Logged out: 2 Time(s) in IDLE: 12 Time(s) **Unmatched Entries** dovecot: IMAP(godfrey): Connection closed: 4 Time(s) dovecot: IMAP(godfrey): Corrupted index cache file /home/godfrey/Maildir/dovecot.index.cache: invalid record size: 1 Time(s) dovecot: IMAP(igodfrey): Connection closed: 4 Time(s) =============== or: Dovecot disconnects: Inactivity: 23 Time(s) Logged out: 1 Time(s) in IDLE: 6 Time(s) **Unmatched Entries** dovecot: IMAP(godfrey): Connection closed: 8 Time(s) dovecot: IMAP(godfrey): Corrupted index cache file /home/godfrey/Maildir/.Sent/dovecot.index.cache: invalid record size: 1 Time(s) dovecot: IMAP(godfrey): Corrupted index cache file /home/godfrey/Maildir/dovecot.index.cache: invalid record size: 1 Time(s) dovecot: IMAP(igodfrey): Connection closed: 6 Time(s) ---------------------- Dovecot End ------------------------- ========================================================= These errors do not seem to cause any serious problem, but it would be good if the problem could be fixed. I have seen other "corrupted" error reports in the mail archive, but they did not seem to be exactly like this one.

[Dovecot] Dovecot index, NFS, and multiple architectures
by David Halik 28 Jun '08

28 Jun '08

Hi all, I crawled through the archives for a bit but didn't see anything helpful, so I apologize if this has already been addressed. We've been dying to move from Courier to Dovecot across our whole infrastructure for quite some time, but until recently our setup wasn't possible until this happened: "Dovecot allows mailboxes and their indexes to be modified by multiple computers at the same time, while still performing well. This means that Dovecot works with NFS and clustered filesystems." Now that NFS is officially supported, we figured why not make the switch. All of our mail touches NFS in some way, so we need to check on the stability before completely migrating. In test trials we're having issues with the NFS'd index becoming corrupted. Here's the setup: * Linux workstations running Fedora 8/9 i386 and a locally called Dovecot 1.0.14 * NFS'd homedir with Maildir setup * NFS is on Solaris 9 sparcv9 (64bit) running Dovecot 1.0.14 Now this setup is just a test example and not exactly what we'll be running in production, but it tipped up the problem either way. Since the index is shared by both the Linux i386 machine and the sparc64 Solaris machine, if mail is accessed from both, lets say with Pine for example, the index becomes corrupted and breaks. As long as only one architecture only ever touches it there are no issues. I'm assuming this is an endian issue, which would make the most sense. Is there a way around this with flags or server options? Is this something that has maybe been addressed in 1.1.0? Unfortunately, we are not going to be able to move to Dovecot across all of our systems until this is no longer an issue. We run a lot of mixed environments that have everything from Linux i386/x86_64 to Solaris 9 64 to Windows. If a user accesses IMAP from a Windows box, then logs into the front end which is a Linux x86_64 box and runs Pine, and all of this is on a Solaris sparc NFS system, we're going to have serious issues with the index. ;) Any help would be appreciated.

[Dovecot] Keeping \Seen flag private
by Imobach González Sosa 28 Jun '08

28 Jun '08

Hi all, I wanna to set up shared folders for a couple of users and I'd like that everyone could keep the \Seen flag as private. So if user #1 reads some messages and user #2 not, those messages appear as "unseen" to #2 and "seen" to #1. I've implemented shared folders using namespaces with every user having their own "control" and "private" directories. But all the flags (\Seen included) are "shared". Am I on the right path? Some tip or documentation? Oh, I almost forgot: using dovecot 1.0.13 (from Debian Etch backports). Thank you in advance! -- Imobach González Sosa Banot.net http://www.banot.net/

[Dovecot] managesieve server aware?
by Cassidy Larson 28 Jun '08

28 Jun '08

Just upgraded to Dovecot 1.1 and thought I'd try out managesieve plugin. My situation is I have two front end proxy boxes and four storage nodes in the back. I have been able to load the managesieve plugin just like I should on the storage nodes, but not on the proxy boxes. My proxy boxes have multiple server sections to deal with unique configurations for 5-7 different mail domains: server mail.host1.com { listen a.b.c.d protocols = imap imaps pop3 pop3s ..... } server mail.host2.com { listen a.b.c.e protocols = imap pop3 .... } If I add the managesieve to the protocols line like I do on my storage nodes, I get this: Error: Can't access mail module directory: /usr/local/lib/dovecot/managesieve: No such file or directory Funny thing is /usr/local/lib/dovecot/managesieve does not exist on the the proxy boxes. It also does not exist on the storage boxes where managesieve loaded just fine. Anybody have any ideas or suggestions? -c

[Dovecot] Problem Compiling 1.1.1 on AIX
by Jackie Hunt 27 Jun '08

27 Jun '08

Hi all, We've been running Dovecot since December '07 with with no glitches. It's a great solid piece of software, thanks so much Timo!! I thought I'd try out 1.1.1, so I brought it down and tried compiling it on AIX, using the IBM compiler, xlc. It's what I've used all along. The error I'm seeing on the make is: source='array.c' object='array.o' libtool=no DEPDIR=.deps depmode=aix / bin/sh ../../depcomp xlc -DHAVE_CONFIG_H -I. -I../.. -I/usr/local/openssl_0. 9.7e/include -g -qcpluscmt -c array.c "macros.h", line 149.68: 1506-211 (S) Parameter list must be empty, or consist o f one or more identifiers separated by commas. make: 1254-004 The error code from the last command is 1. Looking at macros.h, the section it is erroring on is: #ifdef CONTEXT_TYPE_SAFETY # define CONTEXT_CALLBACK(name, callback_type, callback, context, ...) \ ({(void)(1 ? 0 : callback(context)); \ name(__VA_ARGS__, (callback_type *)callback, context); }) #else # define CONTEXT_CALLBACK(name, callback_type, callback, context, ...) \ name(__VA_ARGS__, (callback_type *)callback, context) #endif The second define is the line the error occurs on. Has anyone seen this before. I'm assuming xlc can't handle the '...' parameter, and an hoping there is an option I can enable. Just thought I might see if anyone else has already solved this issue. Thanks much! Jackie ---- Jackie Hunt ACNS Colorado State University Fort Collins, CO 80523

[Dovecot] maildirmake -q quota equivalent to set quota
by Eric PEYREMORTE 26 Jun '08

26 Jun '08

Hi, I'm coming from courier-imap and i'm trying to migrate to dovecot. I can't find how to create a maildir with a quota file(maildirsize) I saw that if there was a maildirsize it would get its quota from there but can't find how to create that file. I'm using pam auth and would like to set different quotas for each users. With courier-imap there is a useful command : maildirmake -q 100000S Maildir/ to assign a quota to a maildir. But i don't know how to do with dovecot... Cheers, Erc PEYREMORTE

[Dovecot] local rimapd not working with 1.1.1, fatal error
by David Halik 25 Jun '08

25 Jun '08

Hi all, I just upgraded a couple of Fedora 9 workstations to try out 1.1.1 over NFS'd homedir's and I'm having trouble running dovecot in the same configuration we were with 1.0.14. It's fairly simple, we use pine/alpine and set a couple of variables to fork rimapd directly: * smtp-server=host (for the main mail machine) * user-domain=host (same) * set the inbox-path={localhost}INBOX * ssh-command=%s %s %s %s * ssh-path=/etc/rimapd In rimapd we specifiy: exec /usr/sbin/dovecot --exec-mail imap 2>/dev/null In dovecot.conf we specify: protocols = imap listen = localhost mail_location = maildir:~/Maildir:INDEX=<path>/index/%u:CONTROL=<path>/control/%u namespace public { separator = . prefix = INBOX. inbox = yes } protocol imap { mail_executable = /usr/libexec/dovecot/imap mail_plugins = quota imap_quota } ...and away we go. This enables us to run pine and dovecot locally on the workstations since our home directories are all NFS'd to a central server, essentially giving us Maildir access anywhere local. This has been working great for a long time, and we still use it with 1.0.14, but as soon as I upgraded to 1.1.1, pine is telling me: "rsh to IMAP server timed out" "localhost,143: Connection refused" I know this is very pine specific, but our pine configuration hasn't changed, only dovecot has. I check the obvious answers like perms, and ensured the same dovecot conf exists, and it does. I'm pretty stumped. It's obviously the newer dovecot causing problems, but I don't know where exactly. If I run "/usr/sbin/dovecot --exec-mail imap" manually, i still get the normal IMAP session. The only error I see anywhere is this in /var/log/maillog: Jun 24 15:36:28 host IMAP(user): : Fatal: io_loop_handle_add: epoll_ctl(1, 2): Operation not permitted That doesn't really tell me much though. Any ideas? Is dovecot taking different arguments now so my rimapd line isn't working properly? Any help would be appreciated. Thanks. -- ================================ David Halik System Administrator OIT-CSS Rutgers University dhalik(a)jla.rutgers.edu ================================

Ehlo all, I've been working on a migration of about 240K users from one server with qmail, courier imap, maildrop and ldap to postfix, dovecot, lda +sieve. Before the migration the server and the storage were always on high load. Before migration: Storage IOPs = 4600 Read average = 2800 Write average = 1800 Storage CPU (Raid5) Crl0 = 50% Crl1 = 50% Server Load = 120 %user = 35 %system = 60 %iowait = 5 %idle = 0 After migration: Storage IOPs = 3000 Read average = 1200 Write average = 1800 Storage CPU (Raid5) Crl0 = 40% Crl1 = 40% Server Load = 25 %user = 10 %system = 27 %iowait = 40 %idle = 23 And now the server responds so quickly to any imap command. Dovecot is now the default imap/pop server here, Thanks Timo. []s, Raphael Costa

[Dovecot] v1.0.13: maildirfolder not being created
by Eduardo M KALINOWSKI 23 Jun '08

23 Jun '08

Hi, I'm using version 1.0.13 of dovecot. I know it's somewhat dated, but that's the latest that Debian etch offers, and I would like to avoid compiling by myself if possible. dovecot is not creating the 'maildirfolder' in folders that are created via IMAP. Looking at the NEWS file, this was implemented in v1.0.rc7, so my version should have that working already. Is there anything else that needs to be done? Here's dovecot -n: # 1.0.13: /etc/dovecot/dovecot.conf log_path: /var/log/dovecot/main.log info_log_path: /var/log/dovecot/info.log log_timestamp: %Y-%m-%d %H:%M:%S ssl_cert_file: /etc/ssl/certs/server.pem ssl_key_file: /etc/ssl/private/server.pem login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login login_processes_count: 1 first_valid_uid: 100 mail_privileged_group: mail mail_location: maildir:/home/vmail/%d/%n/INBOX:INDEX=/home/vmail/%d/%n/dovecotidx mail_plugins: quota imap_quota auth default: mechanisms: plain login cram-md5 passdb: driver: passwd-file args: /home/vmail/%d/db/passwd passdb: driver: pam userdb: driver: static args: uid=104 gid=8 home=/home/vmail/%d/%n userdb: driver: passwd socket: type: listen client: path: /var/run/dovecot/auth-client mode: 438 plugin: quota: maildir:ignore=Trash -- I want the presidency so bad I can already taste the hors d'oeuvres.

[Dovecot] Testing using namespaces
by Kyle Wheeler 23 Jun '08

23 Jun '08

Hey there, I'm interested in testing out using different storage formats for different folder hierarchies. I *think* this can be achieved using namespaces, but I'm not sure. For example, is it possible to, say, make all directories under INBOX.Archive be stored as mboxes, while everything else is stored as Maildirs? ~Kyle -- May your glass be ever full. May the roof over your head be always strong. May you be in heaven half an hour before the devil knows you're dead. -- Old Irish Toast

[Dovecot] v1.0.15 released

23 Jun '08

http://dovecot.org/releases/1.0/dovecot-1.0.15.tar.gz http://dovecot.org/releases/1.0/dovecot-1.0.15.tar.gz.sig Still some last fixes to v1.0 series: - IMAP: SORT SUBJECT and THREAD didn't create base subjects correctly - Maildir: Expunged messages may have never gotten removed from dovecot-uidlist - mbox: Fixed a crash when adding a new X-IMAPbase: header with keywords. - Multiple "socket listen" auth blocks should have been possible, but Dovecot failed to start with a "With connect auth socket no other sockets can be used in same auth section" error.

[Dovecot] no maildirsize file being created -dovecot v1.1
by Barry R Cisna 22 Jun '08

22 Jun '08

Hi Timo, Thanks for the info. You are exactly right ,,after I done some researching. by default the Fedora and El distros setups up mail folders in mbox format. My Bad. I was always under the impression default was maildir.I have used sendmail>Procmail>dovecot>squirrelmail for my new setup same as the last email server setup.I found that sendmail seems to be much less CPU intensive than postfix,or I did not have the config correctly as postfix was easy to setup but really choked our email server when a secretary " bulk emailed" everyone in the school district. I have learned a lot about this in the last couple days. I thought I knew a little bit about this,but obviously I didn't know a thing. I am going to go with the default dovecot rpm that ships with EL5 1.0.1x as this does what all I need to have done. My main concern is the check_quota plugin available for Squirrelmail works,and with the dirsize quota directive put into dovecot.conf this is working very slick, and appears to be reporting very accurately.Now hopefully some teachers will not end up with 1GB mail folders!! and complaining the mail server is so slow when they check their email via Squirrelmail at home! Thanks again for steering me straight! Take Care, Barry Cisna

[Dovecot] Cygwin and dovecot-auth problems
by TBlack 22 Jun '08

22 Jun '08

Hi all. I'm trying to install Dovecot 1.1.rc13 on Cygwin. I've read the related posts, and I realize that maybe there's no solution at present; since I'm having a different error, though, I'm posting it here. Compilation succeeds. Starting dovecot from command line results in: Warning: fd limit 256 is lower than what Dovecot can use under full load (more than 640). Either grow the limit or change login_max_processes_count and max_mail_processes settings Warning: Last died with error (see error log for more information): Auth process died too early - shutting down Trying to run just dovecot-auth outputs: dovecot-auth: Fatal: MECHANISMS environment is unset Now, if I try to set an environment variable called MECHANISMS (say, export MECHANISMS=plain) I get a different error: dovecot-auth: Fatal: No passdbs specified in configuration file. PLAIN mechanism needs one This is the output of dovecot -n: # 1.1.rc13: /usr/local/etc/dovecot.conf Warning: fd limit 256 is lower than what Dovecot can use under full load (more than 640).

[Dovecot] Using sork-passwd from Horde to change dovecot password
by Eduardo M KALINOWSKI 22 Jun '08

22 Jun '08

I'm using in my server dovecot and Horde to provide IMAP and Webmail for virtual users. Their password are stored in a passwd file, since the setup is quite simple and small. I'd like to use the Horde module sork-passwd to allow changing of the passwords. Apparently, this can be done for the case of passwd file by using an expect script, or simply calling a program that receives the data. It should not be hard to write a Perl (or Python, or whatever) script that does that. I'm just asking if someone has already done that and is willing to share the solution.

[Dovecot] no maildirsize file being created -dovecot v1.1
by Barry R Cisna 21 Jun '08

21 Jun '08

Hi Timo, I changed the maildir directive in my dovecot.conf as you suggested. The maildirsize file IS created now , but, the ~/mail folder structure is now showing all messed up for the user that logs into Squirrelmail for example: Before the mail_location was changed; ~/mail/Drafts,Sent,Trash,.subsciptions/.imap/Drafts,INBOX,Sent,Trash After, mail_location = maildir:~/mail ~/mail/cur/new/tmp/.Drafts,.Sent,.Trash,dovecot.index.log,subsciptions,maildirsize/.imap/Drafts/INBOX/Sent/Trash Notice how after the maildir directive change there are .DOT in front of Drafts,Sent,Trash as well as no .DOT in front of subsciptions,as well as the added cur,new,tmp directories under the ~/mail folder?? And yes this is the default EL5 install with maildir storage( not mbox). As I stated earlier, if i simply 'rpm -e dovecot' them 'rpm -ivh dovecot' with the default install of the dovecot rpm that shipps with EL5 everything comes up correctly as far as quotas for dovecot, Squirrelmail,etc. I think I may just stick with the default dovecot1.0.1.2-rc15.el rpm that ships with EL5 for now. I'm afraid of other underlying problems i may find as I we start using dovecot v1.1 when school starts then I will be in trouble! Another sidenote: After installing dovecot1.1 rpm dovecot appears to start fine with no errors,,but it is not actually listening on port 143 by doing an nmap localhost. I had to change listen = [::] to listen = * then restart dovecot,then dovecot was listening on port 143 as it should. Thanks for the help, Barry Cisna

[Dovecot] no maildirsize file being created -dovecot v1.1
by Barry R Cisna 21 Jun '08

21 Jun '08

Hello List, Getting ready to setup a new dovecot sendmail squirrelmail server for our school which is currently running on a 4 year old install of the same, which has worked like a champ by the way. --------------------- EL5 dovecot-1.1 rc10 rpm sendmail squirrelmail --------------------- Problem: I can not get my dovecot 1.1 rc10(rpm) to generate an maildirsize file in each of the users homedir. I have re-edited the dovecot.conf file many many times but still no joy. If I uninstall and install the default dovecot 1.0.1x rpm that ships with EL5 i get the maildirsize file to generate correctly without a hitch. I am wanting to use the check_quota plugin for SM this time so I need to get this functioning correctly. How would I go about troubleshooting this. The only error I get in maillog is when I log into SM I do see were dovecot tries to check for the maildirsize file but it can not find it of course and then says " skipping quota check",,so I think I have my dovecot.conf file setup correctly. Dovecot is simply not generating the maildirsize file. Following lines added to the end of dovecot.conf file: protocol imap { mail_plugins = quota imap_quota } protocol pop3 { mail_plugins = quota } # In case you're using deliver: protocol lda { mail_plugins = quota } plugin { quota = maildir quota_rule = *:storage=1GB # 10% of 1GB = 100MB quota_rule2 = Trash:storage=10%% # 20% of 1GB = 200MB quota_rule3 = Spam:storage=20%% } ,,I have reversed the above to have quota=maildir,,etc above the protocol directives as well and still no joy. Sidenote: I also tried dovecot v1.1 rc5 rpm as well with the same results. Any tips from anyone would be appreciated. Thanks, Barry Cisna

by Marc Perkel 21 Jun '08

21 Jun '08

OK - I wish I had more details but I'm using rc11 for the server and Thunderbird for the client. I'm using Maildir and I'm doing server side folder delivery using Exim. On server side folders I'm seeing the count of messages in a folder showing 22 unread messages but the messages themselves don't show up. I deleted the index files and it still didn't show up. But then I restarted dovecot and now the messages in that folder are there. I've noticed similar behavior randomly ever since I upgraded to 1.1. The 1.0 never had this problem. Wish I had more details to post.

[Dovecot] Quota warning question
by Torsten Krah 20 Jun '08

20 Jun '08

Hi. Read the example conf and doku about the quota warning stuff, but how might such a "sh" file may look? If i want to sent a mail to the user, how to get the mail address? Wheres the glue between the "sh" file and the percentage given and the user? thx for hints Torsten -- Bitte senden Sie mir keine Word- oder PowerPoint-Anhänge.

[Dovecot] v1.2 development tree started
by Timo Sirainen 20 Jun '08

20 Jun '08

I merged all the new features and latest v1.1 changes under one tree: http://hg.dovecot.org/dovecot-1.2/ The changeset order is kind of weird though. The timestamps jump all around. Wonder if there's a way to reorder them so that it looks more sane.. The status of the new features: 1. CONDSTORE extension is probably the largest change. It adds new "modification sequences" for messages that increase whenever the message's metadata changes. I'll probably have to reimplement the way modseqs are calculated, because modseqs will be very useful when implementing replication and the current way just doesn't work with it. If modseq-supporting clients see the current modseqs and later the server gets upgraded to new modseqs, the clients will most likely break. So this change should be done for v1.2. 2. QRESYNC, ESEARCH, SEARCHRES and WITHIN extensions are fully implemented. QRESYNC might need some cleanups and optimizations though. 3. CONTEXT=SEARCH extension is fully implemented, but could use a few optimizations (caching PARTIAL and CONTEXT searches, maybe others too). 4. Virtual mailboxes should work fast after mailbox is opened. The initial opening could use several optimizations though. It could probably share some code with QRESYNC to avoid the full initial search (storing each backend's modseq to index header). Also if search parameters don't contain any dynamically changing data, there's no point in searching the old messages. The current design doesn't allow changing the search parameters or list of mailboxes, otherwise it breaks more or less badly. I guess I could add code to check if the dovecot-virtual file's mtime has changed and if so make it do a full resync. This anyway means that there's no way to support wildcard mailbox names (e.g. "all mailboxes"). But does anyone really want that (yet)? It'll anyway be faster/easier to implement once mailbox list indexes are implemented. I'll still have to add a new X-MAILBOX search parameter which can be used to test what the backend mailbox name is. This will be especially useful with INTHREAD extension. I guess it wouldn't hurt to have FETCH X-MAILBOX if someone wants it. 5. Thread indexes should work, but some optimizations missing and there are some small bugs left. X-REFERENCES2 thread algorithm works. 6. INTHREAD extension isn't started yet, but I'll start it soon. Hopefully won't be too tricky to get it working with virtual mailboxes and CONTEXT=SEARCH..

[Dovecot] sig11 in 1.1rc5 fts
by Adam McDougall 20 Jun '08

20 Jun '08

This happened from one user near noon on the 17th and 19th (today) of this month. From the backtrace it looks like they were searching, but I won't know for sure unless I need to ask them. Is this possibly fixed already? I just haven't upgraded dovecot in a while due to lack of problems. The sig11 happened a few dozen times, a few seconds apart each day. I have one coredump from each day, and the size was the same. This is a trace from only one. The other backtrace looks pretty much the same.

Did you test it without index files? I couldn't reproduce the crash. Do you use 32bit or 64bit Dovecot?

Hi, I am getting a lot of warnings since upgrading to 1.1rc10 (from rc4): mbox /home2/seta/Mail/Sent: Can't find next message offset for uid=12 Almost always, it is the Sent or Trash folders that are giving these.

[Dovecot] Migrate to 1.1 from 1.0.14
by Nicolas Letellier 19 Jun '08

19 Jun '08

Hello. I see dovecot 1.1 will be release very soon. I'm thinking about a migration from my 1.0.14. The migration job will be hard/long? I see in http://wiki.dovecot.org/Upgrading/1.1 that dovecot-uidlist file are in a new format. It will be problem for Courier (pop/imap) upgrades? (today, I often upgrade old mailboxes in Courier to my Dovecot server). Best regards, -- - Nicolas.

[Dovecot] Using checkpassword to block ips?
by Larry Ludwig 19 Jun '08

19 Jun '08

Hi new to the list, but we are a long time user of Dovecot via DirectAdmin control panel. We, like everyone else, are seeing an increase in dictionary attacks of POP/IMAP. We want to block them. I've searched the mailing list and found a few recommended fail2ban, which really won't work for our case. We need to do this over many machines and not one or two. We also like to gather info at the network wide level. Hackers know about attacking specific server/ips too often and we've seen much more distributed attacks that go under the radar of one server monitoring setup. We've designed our own system and use a local RBL to distribute the blocked IPs. For ftp and ssh attacks it's worked very well. We would like to use the RBL to do the same with dovecot. >From my research it appears the best way to do this (and only currently) is with the checkpassword option. I haven't gotten it to work yet. We have: passdb checkpassword { args = /usr/local/bin/checkpassword deny = yes } As the first auth.. This should reject the connection if the IP matches. checkpassword can see TCPREMOTEIP enviornmental variable. In the checkpassword script we have: #!/usr/bin/perl sub read_uinfo { my($user,$passwd,$apop_ts); open X,"<&=3" or exit 111; $_ = <X>; # ugly; should use sysread instead ($user,$passwd,$apop_ts) = /^(.*)\0(.*)\0(.*)\0/; while (<X>) {}; close X; return ($user,$passwd,$apop_ts); } ($user,$passwd,$apop_ts)=$debug?(shift,shift,shift):read_uinfo; $ipaddr=$ENV{TCPREMOTEIP}; $result=system("/usr/sbin/checkdnsbl $ipaddr"); if ( $result == 0) { @ENV{"SHELL","USER","HOME"} = ($shell,$user,$home); exit 0; } else { exit 1; } My questions are as follows: - Can the deny = yes be used with checkpassword? - What am I doing wrong with the script? It should reject only the connections that are in the RBL. It blocks all -L -- Larry Ludwig Empowering Media 1-866-792-0489 x600 Managed and Unmanaged Xen VPSes http://www.hostcube.com/

[Dovecot] quote-warning details
by Alexander Prinsier 19 Jun '08

19 Jun '08

Hello, I have some questions on how quota-warning is supposed to work. -Does it keep a state, so that it doesn't send the same warning several times? Or should the script itself do something to remember it already sent a warning? -When exactly does it run? Does it run when deliver runs? Or only when the user accesses it's mailbox?

[Dovecot] dovecot as gmail imap proxy
by Farkas Levente 18 Jun '08

18 Jun '08

hi, may be this is a bit of topic, but i hope not. it's always a big question which is the better to choose a hosting provider to keep and manage you mail or setup your own mail server, hosting, virus and spam filter etc.. now as more and more people and company move to gmail or google apps mail service it seems google can't handle the load and it's getting more and more slower. what's more not just the imap interface but nowadays the web interface used to be hang or even stop working. it's getting more and more annoying that the speed is worst than in a 10 years ago. i thing about how can this be solved without totally give up gmail as a mail service provider (and may be they can solve it in a few months/years:-). would it be possible to create a dovecot server as an imap proxy for gmail and google apps? imho many people/company would be love to use such a setup where he can use gmail in vacation or any other time, but when the email is real critical apps (not acceptable to wait 1 minutes for an email to load or to open a folder/label) than he can use a proxy server eg. dovecot which act as a imap proxy to gmail and can be hosted on closer, faster server and this speed problem never happend. what's more it can be used as a mail backup server too. anybody has any such setup, idea? would it be possible with dovecot. any other suggestion? yours. -- Levente "Si vis pacem para bellum!"

[Dovecot] don't follow symlinks when creating mailbox list
by Dan Horák 18 Jun '08

18 Jun '08

Hi, this issue was discussed here twice in the not so far history (http://www.dovecot.org/list/dovecot/2008-January/028317.html, http://www.dovecot.org/list/dovecot/2008-February/029147.html) but I need to open it again as it makes problems for our users on one side and on the other side we don't want to diverge from the upstream sources in our packages. I agree with Timo that simply disabling the symlink following in creating the mailbox list can give a false sense of security so the question is whether a permanent solution can be developed and how it should look like? Regards, Dan -- Fedora and Red Hat package maintainer

[Dovecot] dovecot-uidlist cleanup

http://dovecot.org/releases/1.1/rc/dovecot-1.1.rc10.tar.gz http://dovecot.org/releases/1.1/rc/dovecot-1.1.rc10.tar.gz.sig v1.1.0 will be released on next Friday if nothing horrible happens. * LIST X-STATUS renamed to LIST STATUS and fixed its behavior with LIST-EXTENDED options. It's now compatible with STATUS-IN-LIST draft 00. - Message parsing could have sometimes produced incorrect results, corrupting BODY/BODYSTRUCTURE replies and perhaps others. - SORT: Fixed several bugs - FreeBSD 7.0: Environment clearing wasn't working correctly. This caused "environment corrupted" problems at least with deliver trying to call sendmail and running Dovecot from inetd. - HP-UX: Several fixes to get it to work (by Christian Corti) - Fixes to using expire plugin with SQL dictionary. - dbox fixes

[Dovecot] Mercurial repositories for ManageSieve and Sieve
by Stephan Bosch 17 Jun '08

17 Jun '08

Hello Dovecot users, Recently I was asked to use Mercurial for the ManageSieve development just like Dovecot. As a matter of fact I have been using Mercurial for some time now. Now that I am back from a short and active vacation I am ready to publish my repositories. The repositories are publicly available at: http://hg.rename-it.nl/ The -patch repositories are so-called Mercurial Queues (MQ) repositories. This provides an easy (quilt-like) means to manage patches over an upstream source repository like the one that exists for Dovecot. The patches are managed in a repository called 'patches' below the .hg directory in your main repository. Currently, these MQ repositories only have the managesieve.patch witch is the actual patch I refresh and release each time Timo makes a new Dovecot release. The following command sequence shows how to incorporate the managesieve patch repository in a freshly cloned dovecot-1.1 tree: hg clone http://hg.dovecot.org/dovecot-1.1 cd dovecot-1.1 hg clone http://hg.rename-it.nl/dovecot-1.1-managesieve-patch .hg/patches hg qpush When updating the dovecot tree it is important to unapply all patches before performing 'hg pull' on the dovecot tree: hg qpop --all hg pull hg update hg qpush This otherwise results in a multi-head situation which can be resolved using a 'hg rollback' or using 'hg qpop --all' afterwards, which should gracefully clean up the situation (never merge the heads!). Updating the patch repository works as follows: hg qpop --all hg -R .hg/patches pull hg -R .hg/patches update hg qpush After 'hg qpush' the dovecot repository is patched and can be compiled as explained for the normal patch method using the .diff.gz (don't forget ./autogen.sh for compiling dovecot in a mercurial repository). The actual ManageSieve implementation for Dovecot-1.1 is available as a separate package and thus there exists a separate repository for it. Its compilation is no different from the .tar.gz releases, except for the fact that (just like for dovecot) ./autogen.sh needs to be executed before configure. The new (and highly experimental) Sieve implementation is available as the dovecot-libsieve repository. It contains a README file that should explain most of its features and the installation procedure. This is currently still not release-ready and should not be used for any important mail whatsoever. I publish this for people who want to test and play around with it to provide feedback on early bugs and (release-critical) missing features. The TODO and README files provide an overview of my current progress towards a first release. Regards, Stephan.

[Dovecot] quota-warning.sh
by Drew Marshall 17 Jun '08

17 Jun '08

Hi I have just installed Dovecot (Moved from Courier-IMAP) and have just about everything running well thanks to some great docs in the wiki (Thank you to all those who contributed!) however I have not managed to get the quota warnings working yet. I have done much Googling and come back with some oldish posts which help me to understand how the quota warnings work but having looked at all this I have realised I don't have a quota-warning.sh script in /usr/local/bin where the config suggests it ought to be. In fact, I don't have a file by this name any where on the box. I have downloaded both 1.1 source (Which I'm running) and 1.0 and I can't find this anywhere in the sources or the tarball. Could some one tell me where I can find this or am I supposed to make my own? If so is there and example that I can follow?

[Dovecot] Caseless folder delivery?
by Jay Levitt 16 Jun '08

16 Jun '08

I'm using exim4 to deliver into dovecot 1.1, and using plus-addressing to deliver mailing lists directly to appropriate folders in my "lists" mailbox. I created a file called /folder-map.lists that looks like ## folder-map.lists dovecot: Dovecot lpedge: Linux PowerEdge ... and so on. So mail to lists-lpedge(a)jay.fm goes to the "Linux PowerEdge" folder. The one annoying thing: I'd like to avoid creating explicit folder-map entries where the plus-address suffix is identical an existing folder name. That *almost* works, but I like to name my folders with appropriate capitalization, and deliver doesn't seem to have a way to do "caseless" delivery. For instance, ideally, I wouldn't have to create the "dovecot: Dovecot" entry; mail to my lists-dovecot(a)jay.fm address would go into the "Dovecot" folder. I can't figure out how to do this. Is there a way to do that using deliver? Could there be? Relevant portions of the exim configuration follow. (And, p.s., am I using the new -a and -m options correctly? Are they used for anything yet?)

[Dovecot] Need help configuering Dovecot to support folders that contain sub-folders and messages
by Dan Roberts 14 Jun '08

14 Jun '08

Hi - Last year I set up a new CentOS 5 server and through the install process permitted it to set up dovecot as my IMAP server. ./dovecote --version returns "1.0.rc15" With the system up and running I moved the tar files of my old email accounts over and everything seemed to be just fine. Recently I have upgraded my primary workstation to a Mac Pro - and that of course has it's Mail application. Let me summarize briefly to be sure that I don't omit some minor detail that makes all the difference in the world. Previously I used Netscape 7.2 as my mail client and then went over to Thunderbird on the PC - in either application, under Server Settings / Advanced I had to uncheck the box "Server supports folders that contain sub-folders and messages". Then whenever I attempted to add a new subfolder I would be given a choice - "This server restricts folders to two special kinds. Allow your new folder to contain: [] Folders Only [x] Messages Only". Though perhaps not ideal, this has worked ok up till now. The Leopard Mail application doesn't seem to have this sort of support - it assumes that every folder or subfolder can and should contain both, so all I get are folders that can hold messages. This is a problem as I can't create any new folders to reorganize mail. Though I had thought about resolving this, or at least trying to when I first encountered it - life got busy. So my skills have become a bit rusty and I have not done anything about it. But now I would like to. I ported over my email and my wife's - so perhaps there is some legacy setting in those folders that prevents the bliss of folders and mail in the same subfile. But I created a new email account for my daughter and that has the same limitation. In Leopard mail, folders to hold folders look White, whereas folders to hole mail look blue. In Thunderbird Folders to hold Folders are in Italics whereas Folders to hold mail are normal font. I am also using Webmin to simplify access to the server, but I don't see anything obvious under the dovecot tool for this. The installation was the basic default, so far as I can remember. I have run Yum to update the files and at last review there was nothing outstanding. Regarding my configuration, dovecot -n reports as follows: [root@trailrunner sbin]# ./dovecot --version 1.0.rc15 [root@trailrunner sbin]# ./dovecot -n # /etc/dovecot.conf base_dir: /var/run/dovecot/ protocols: imap imaps listen: disable_plaintext_auth: yes login_dir: /var/run/dovecot//login login_executable: /usr/libexec/dovecot/imap-login mail_extra_groups: mail mail_location: mbox:~/mail:INBOX=/var/mail/%u auth default: passdb: driver: pam userdb: driver: passwd [root@trailrunner sbin]# Truly hoping that someone can help me resolve this. While I can use Thunderbird, I do like the Apple Mail feature of seeing the summary of email at the top of the list. Appreciate the help and insights - Cheers Dan

[Dovecot] Need a quick, safe method to empty /home/user/Maildir/{.Junk, .Trash}
by Jeff Kowalczyk 13 Jun '08

13 Jun '08

I have some (Thunderbird client, dovecot-1.0.13, Maildir) users who get an appalling amount of spam-with-attachment, and it's causing backups to take an inordinate amount of time. I'll implement some quota and server-side spam management when I go to dovecot-1.1, but in the meantime: What is the safest way to empty all messages within, but not delete, the following folders from the server command line: /home/user/Maildir/.Junk /home/user/Maildir/.Trash I don't want the Thunderbird-2.0.14 client to report corrupt indexing, or worse not show the folder at next use. Thanks.

[Dovecot] 9GB of messages in /tmp
by Charles Marcus 13 Jun '08

13 Jun '08

Hello, Well, I have a brain-dead user (using Thunderbird 2.0.0.14) who just won't listen when I tell them not to try to move 5000+ messages at one time (or if deleting, bypass the Trash), and they managed to royally screw up their maildirs... I have two problems... 1. The /tmp directory has 9+GB in it... can I just rm tmp/* on that directory without making this problem worse? and 2. One of the directories they were moving now has 5 copies of a whole bunch of messages... I'm very dangerous when it comes to command-line work beyond really basic stuff, and my scripting skills are less than inspiring... Is there a relatively safe command-line way of finding all messages that have more than one instance, and deleting all but the last instance? Tia... -- Best regards, Charles

[Dovecot] "Disable non webmail IMAP access" in vpopmail and Dovecot
by Alessio Cecchi 13 Jun '08

13 Jun '08

Hello, i'm using in my installation qmail+vpopmail and now I have migrated from courier-imap to dovecot. Dovecot is very much faster with large mailbox than courier-imap. But I have a problem. vpopmail has a feature that allows you to "Disable non webmail IMAP access", many webmail using imap as if they were, and they are, a client IMAP. vpopmail give me the ability to disabile IMAP, expect for 127.0.0.1, both for individual users than for single domain. So i can grant IMAP access, from remote client, only for some users but webmail access for all. Here you can read some of my messages in the vpopmail's list: http://www.mail-archive.com/vchkpw@inter7.com/msg25880.html But with dovecot this feature seems not to be compatible. A friend of the vpopmail's list sent me a patch for dovecot but I can not get it to work: >->->->->->->->->->->->->->->->->->->->->->->->->->-> Hi Alessio, i spent over 5 hours looking for a solution to this problem and i found one working for me in dovecot sources edit src/auth/passdb-vpopmail.c than add char *remotehost = net_ip2addr(&auth_request->remote_ip); auth_request_log_info(auth_request, "vpopmail", "remote ip is: %s", remotehost); before if (((vpw->pw_gid & NO_IMAP) != 0 && line than modify the condition line to look like: if (((vpw->pw_gid & NO_IMAP) != 0 && strcmp(auth_request->service, "IMAP") == 0 *&& strcmp(remotehost, "127.0.0.1") != 0*) || ((vpw->pw_gid & NO_POP) != 0 && strcmp(auth_request->service, "POP3") == 0)) { auth_request_log_info(auth_request, "vpopmail", "%s disabled", auth_request->service); password = NULL; *result_r = PASSDB_RESULT_USER_DISABLED; } else ............... this way you will preserve webmail access and cut imap from external in case -i limit is defined in vpopmail hope it helps <-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-< Can someone help me in making compatible this useful feature of vpopmail with dovecot?

Hi All, I tried to build dovecot-1.1.rc9 on a HP-UX machine, but failed to configure with the following message: configure: error: You don't appear to have C99 compatible vsnprintf() call The environment is like the following: - command: ./configure - uname: HP-UX B.11.23 U ia64 - aCC version: HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003] Also, I tried to run `./configure CC=c99' and `./configure CC="/opt/aCC/bin/aCC -Ae" also, but the result was the same. I'm not sure, but the HP C compiler does not seem to support C99 fully with vsnprintf() call. Is there any workaround for this problem? TIA, Woonsan

[Dovecot] [Patch] Fix delay on imao-append
by Bruno Prémont 13 Jun '08

13 Jun '08

Dovecot version: 1.1-rc8, 1.1-rc9 System: Linux-2.6.2x User-Agent: claws-mail-3.3 and 3.4 When appending messages (e.g. copy from mailclient local folder or second server to dovecot imap folder) dovecot answers with: <tag> OK [APPENDUID <n> <m>] Append completed\r\n This answer often reaches the client as two or more TCP packets, the client (when not using TCP_NODELAY on its socket) ACKs with some delay. When copying lots of (small) messages this delay has a very negative impact on copy time even though there are lots of network and system resources available. Sample sniffer output on client host: ... 1 0.0000 claws dovecot IMAP Request: 14639 APPEND "Test" (\Seen) {853} 2 0.0033 dovecot claws IMAP Response: +OK 3 0.0034 claws dovecot IMAP Request: <message> 4 0.0096 dovecot claws IMAP Response: 14639 5 0.0467 claws dovecot TCP 33453 > imap [ACK] 6 0.0481 dovecot claws IMAP Response: OK [APPENDUID 1204729411 2] Append Completed. 7 0.0481 claws dovecot TCP 33453 > imap [ACK] ... The delay of about 35ms between packet 4 and its ACK in packet 5 causes copies from client to server to be extremely slow. (Client and server on same 100Mb LAN, same result if client and server are on same host) The attached patch makes dovecot send the whole answer in a single packet, thus not triggering the delay issue. As far as I found out the delay is generated by Naggle algorithm, this algorithm being used by Linux TCP stack for small packets with the aim of improving payload/overhead share.

[Dovecot] How many imap processes per user
by Martijn de Munnik 13 Jun '08

13 Jun '08

Hi, I'm using dovecot for the first time on a production server (before dovecot I used bincimapd). I have a question about the number of imap (not imap-login) processes created for a user. I've seen 100+ processes for just 1 user. So far it only occurs for 1 user, other users have just 1 imap process. I now the user is using thunderbird and 2 mailclients are logged in at the same time (one workstation and one laptop). Is there an issue with dovecot/thunderbird? info@dem 28596 15780 0 10:48:41 ? 0:02 imap info@dem 28933 15780 0 10:50:57 ? 0:01 imap info@dem 25627 15780 0 10:28:55 ? 0:00 imap info@dem 28938 28933 0 - ? 0:00 <defunct> info@dem 29472 15780 0 10:54:23 ? 0:00 imap info@dem 25628 25627 0 10:28:55 ? 0:00 rawlog /opt/csw/ libexec/dovecot/imap info@dem 29329 29327 0 - ? 0:00 <defunct> info@dem 29805 29801 0 - ? 0:00 <defunct> info@dem 24303 24300 0 10:20:46 ? 0:00 rawlog /opt/csw/ libexec/dovecot/imap info@dem 29941 15780 0 10:58:09 ? 0:00 imap info@dem 28480 28477 0 - ? 0:00 <defunct> info@dem 28329 15780 0 10:46:28 ? 0:03 imap info@dem 29177 29176 0 - ? 0:00 <defunct> info@dem 28749 28748 0 - ? 0:00 <defunct> info@dem 29801 15780 0 10:56:56 ? 0:00 imap info@dem 29180 29179 0 10:52:05 ? 0:00 rawlog /opt/csw/ libexec/dovecot/imap info@dem 29635 15780 0 10:55:35 ? 0:00 imap info@dem 29642 29635 0 - ? 0:00 <defunct> info@dem 28477 15780 1 10:47:37 ? 0:02 imap info@dem 28200 28199 0 - ? 0:00 <defunct> info@dem 29942 29941 0 10:58:09 ? 0:00 rawlog /opt/csw/ libexec/dovecot/imap info@dem 28597 28596 0 - ? 0:00 <defunct> info@dem 28330 28329 0 - ? 0:00 <defunct> info@dem 25610 25609 0 10:28:49 ? 0:00 rawlog /opt/csw/ libexec/dovecot/imap info@dem 28748 15780 0 10:49:48 ? 0:02 imap info@dem 25609 15780 0 10:28:49 ? 0:00 imap info@dem 29176 15780 0 10:52:05 ? 0:01 imap info@dem 29327 15780 0 10:53:12 ? 0:01 imap info@dem 29179 15780 1 10:52:05 ? 0:05 imap info@dem 28199 15780 0 10:45:22 ? 0:03 imap info@dem 29474 29472 0 - ? 0:00 <defunct> info@dem 24300 15780 0 10:20:46 ? 0:00 imap All those processes are really slowing down the server.

[Dovecot] strange looking code and userdb errors
by Tony den Haan 13 Jun '08

13 Jun '08

hi, i'm trying to use passdb ldap and userdb prefetch, using the userdb_ prefixes in pass_attrs, and i get: passdb didn't return userdb entries looking at the code at auth/userdb-prefetch.c i see: if (auth_request->userdb_reply == NULL) { if (auth_request->auth->userdbs->next == NULL) { /* no other userdbs */ auth_request_log_error(auth_request, "prefetch", "passdb didn't return userdb entries"); } else { /* more userdbs, they may know the user */ auth_request_log_info(auth_request, "prefetch", "passdb didn't return userdb entries"); } callback(USERDB_RESULT_USER_UNKNOWN, auth_request); return; } is this really correct? if so it migth be a good idea to at least print different errors Tony

[Dovecot] auth issues on centos5 with ldap backend
by Jurvis LaSalle 13 Jun '08

13 Jun '08

Hi, We've had some issues with auth. /var/log/secure is full of 1000s of these lines: Jun 4 19:12:08 khan dovecot-auth: pam_unix(dovecot:auth): authentication failure; logname= uid=0 euid=0 tty=dovecot ruser= rhost=127.0.0.1 user=user123 Users can usually login OK with their ldap credentials, but occasionally logins slow to a crawl if not outright fail, esp people checking mail through Squirrelmail. Things get better after a dovecot restart. Googling around, I thought if we switched the order or disabled the second passdb we had configured for our dovecotadmin account, these failures would go away but that did not happen. Any thoughts or additional info I can provide? Pardon the unusual install prefix. We're trying to keep the source install separated from the ancient dovecot rpm shipped in rhel5.

[Dovecot] Antispam plugin custom behavior?
by Kyle Wheeler 12 Jun '08

12 Jun '08

Hello, I currently have a setup on my system with what I call "magic folders" to enable spam filter training. Here's how it works: 1. If you have a false-negative, put the spam into the Spam.Report folder 2. If you have a false-positive (which has all kinds of ugly spamassassin protective markup in it), put the message into the Spam.NotSpam folder Currently what happens is that a cron job comes along every five minutes and processes the messages in those folders. In the case of the NotSpam folder, it strips the message of the spamassassin markup, retrains the bayesian net, and redelivers the message (e.g. via deliver). In the case of the Report folder, the message is used to train the bayesian net (among other things) and then deleted. I'd love to be able to trigger these actions when the mail is moved, rather than have a cron job inspecting the mailboxes. I looked into the antispam plugin (http://johannes.sipsolutions.net/Projects/dovecot-antispam) which seems nice but doesn't appear sufficiently generic for my needs. What would really work is if I could get it set up such that putting a message into either of those directories is turned into piping the message to a script of my choosing (a different one for each folder). Does anyone know a good way of getting my own custom behavior in here, or is my cronjob setup probably the best way? ~Kyle -- The optimist thinks this is the best of all possible worlds. The pessimist fears it is true. -- J. Robert Oppenheimer

[Dovecot] quota-rewrite patch & userdb quota overriding
by Alan Premselaar 12 Jun '08

12 Jun '08

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I've spent the past couple of hours trying to figure this out by checking the wiki and googling, but haven't come up with anything that works yet. I just installed dovecot 1.0.14 with the quota-rewrite (1.09) patch and i'm trying to get the quota overridden via a passwd-file type userdb. I had 1.0.13 without the new quota style patched in working but having trouble figuring this out. any help would be appreciated. prior to the quota-rewrite patch (which i installed with the hopes of using quota_warn feature) i was able to put the following line into my passwd-file userdb and it was working: alan:*:1000:1000::/home/alan::userdb_quota=maildir:storeage=2048000:ignore=Sent (which is what I wanted) but now with the new quota definition style, I'm not sure what I need to define the extra fields as. here is dovecot -n: # 1.0.14: /usr/local/etc/dovecot.conf log_path: /var/log/dovecot.log protocols: imap imaps managesieve ssl_cert_file: /etc/pki/tls/certs/dovecot.pem ssl_key_file: /etc/pki/tls/private/dovecot.pem disable_plaintext_auth: no login_dir: /usr/local/var/run/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(managesieve): /usr/local/libexec/dovecot/managesieve-login login_greeting_capability(default): yes login_greeting_capability(imap): yes login_greeting_capability(managesieve): no verbose_proctitle: yes mail_location: maildir:~/Maildir mail_debug: yes maildir_copy_with_hardlinks: yes mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(managesieve): /usr/local/libexec/dovecot/managesieve mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(managesieve): mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(managesieve): /usr/local/lib/dovecot/managesieve sieve_storage(default): sieve_storage(imap): sieve_storage(managesieve): ~/sieve sieve(default): sieve(imap): sieve(managesieve): ~/.dovecot.sieve auth default: ~ passdb: ~ driver: pam ~ userdb: ~ driver: passwd-file ~ args: /usr/local/etc/dovecot.passwd ~ userdb: ~ driver: passwd ~ socket: ~ type: listen ~ master: ~ path: /var/run/dovecot/auth-master ~ mode: 384 ~ user: dovecot ~ group: dovecot plugin: ~ quota_rule: *:storage=1G ~ quota_rule2: Trash:storage=100M thanks, alan -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.8 (Darwin) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkhPd+cACgkQE2gsBSKjZHQNMACghSk7awVX1Aj5HVeo0KjRxyZc lT0AoLJA00SiYiefi2wNrAOt7L6N5eg4 =mA8L -----END PGP SIGNATURE-----

[Dovecot] Wrong message information
by Anders 12 Jun '08

12 Jun '08

We have a few users that every so often get empty data in their message overview. From and subject are empty, and the date is 1-Jan-1970. When opening the message in full view, all things are fine. Also, the data in the actual maildir file is fine. It looks a lot like the issue described here: http://dovecot.org/list/dovecot/2008-March/029282.html The server is Linux, ext3, no NFS, and Dovecot 1.1.rc4. The few clients that have had this problem so far have been Outlook Express. What can be done to debug this? Thanks, Anders.

The correct way has to be one or the other: http://wiki.dovecot.org/LDA/Exim are mutually exclusive with http://wiki.dovecot.org/HowTo/DebianStable It appears that exim can either call dovecot's LDA or make the delivery itself.

[Dovecot] Dovecot 1.1 rc9 compilation warnings

11 Jun '08

I've tried compiling 1.1.rc9 on everything to hand and I get various compilation warnings (but the compilation finishes). I don't know whether any of them are worth tracking down?

[Dovecot] Lucene index not updated when one saves a message from one folder to the other
by Asheesh Laroia 11 Jun '08

11 Jun '08

I'm running 1.1 rc8, and I enabled the Lucene indexes. I find that if a bunch of messages arrive in INBOX and I then move them to archive, the next time I do an X-TEXT-FAST search, Dovecot has to re-index the mails that I think it had indexed when they were in INBOX. This seems silly, since Dovecot was the one copying them (and then deleting, since that's what I mean by move). Will this change? -- Asheesh. -- Elliptic paraboloids for sale.

[Dovecot] Auto creating client folders on the IMAP server after installing client.
by Radio Tron 11 Jun '08

11 Jun '08

Hello, could someone help. I have installed Dovecot+SSL+TLS+Thunderbird and all is well except one thing. After installing TBird and adding the required data (smtp server and auth info, imap/pop server and auth info) I am able to view mail in my TBird Inbox BUT Trash and Sent don't work - it pops up saying folder doesn't exist on the server - can't the darn thing, auto create a folder on the server instead of cribbing to me??? Is there a painless (automatic way) to auto create client directories on the Dovecot server (in the users home dir on the server - i am using maildir/). I don't want to maintain a list of clients(TBird, outlook, eudora..) with their directory structure and then remember what user has what clients installed and Gahhh! How do i do this?? Is this explained/documented somewhere in simple language(for a newbie - I'm struggling through the RFC's but they are awfully obscure and don't seem to answer my question directly)? I've also googled but that's worse. Thank you for your patience and time. I'd like to add that I plan to sync GMail, Dovecot and a multitude-of-stupid-clients in some mysterious way so any advice in advance is more than welcome.

[Dovecot] Multiple SSL certificates with dovecot.
by Andre Rodier 10 Jun '08

10 Jun '08

Hello all, By advance, I hope you'll excuse my probably not perfect English, which is not my mother tongue. I have always appreciated dovecot for this simplicity to setup and lightweight, but today, after many installations, I cannot find how to setup dovecot for my configuration. - I use only IMAPS to retrieve the mails. - I manage two domain names - I use CA-Cert certificates So,the question is : how to setup dovecot to select the appropriate certificate, according to the domain name I use when I retrieve mails using the IMAPS protocol ? Thanks. Andre Rodier.

[Dovecot] inetd & corrupt environment
by Gelu G. Lupas 09 Jun '08

09 Jun '08

Hello. I'm having the following problem with dovecot 1.0.12 and above, on a FreeBSD 7.0 system - I'm trying to run pop3-login from inetd and I keep getting this error after authentication: May 25 09:46:19 charlie dovecot: POP3(gelu): /libexec/ld-elf.so.1: environment corrupt; missing value for no-nuls oe-ns-eoh The problem persists if I uncomment the lines with no-nuls oe-ns-eoh in dovecot.conf. I've also tried running pop3-login from tcpserver/ucspi-tcp and I still get the same error. Version 1.0.1 works fine on a similar setup. Please reply if you have any idea regarding a fix for this error. I need to run dovecot under a tcp wrapper of some kind (preferably inetd) as the standalone daemon doesn't allow any method to restrict access by IP. The allow_nets extra field doesn't help much as I'm using PAM and do not want to maintain yet another passdb. Restricting access via firewall rules is not an option. Until I find a way to restrict access by IP address, dovecot will only listen on the private IP address (192.168.100.1). My dovecot configuration follows: # 1.0.13: /usr/local/etc/dovecot.conf base_dir: /var/run/dovecot/ protocols: pop3 listen: 192.168.100.1 ssl_cipher_list: ALL:!LOW disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/pop3-login login_greeting: login_process_size: 32 login_max_processes_count: 32 login_max_connections: 128 max_mail_processes: 128 verbose_proctitle: yes first_valid_uid: 1000 mail_privileged_group: mail mail_location: mbox:~/Mail/:INBOX=/var/mail/%u mail_executable: /usr/local/libexec/dovecot/pop3 mail_plugin_dir: /usr/local/lib/dovecot/pop3 pop3_uidl_format: %08Xu%08Xv pop3_client_workarounds: outlook-no-nuls oe-ns-eoh auth default: mechanisms: plain login process_size: 64 passdb: driver: pam userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix ---------------------------------------------------------------------- Finally - A spam blocker that actually works. http://www.bluebottle.com/tag/4

[Dovecot] EXPUNGE delay
by Eugene 09 Jun '08

09 Jun '08

Hi people! I just switched one of my servers from Courier to Dovecot. Planned to do it anyway but had to do it faster after the discovery that courier [the version I had installed, at least] returns malformed headers for a few messages, causing Outlook Express to completely ignore them. Curiously, they were visible in Squirrelmail and Nokia Series60 e-mail client. Overal I am quite happy but have one little problem. More often than not, I have to press 'Purge' button two or more times in order to actually remove the deleted messages. The fragment of Outlook's IMAP log is below. Interestingly, Dovecot 1.0.7 (on another server) does not have such problem.

[Dovecot] deliver 1.0 vs 1.1
by arne van theemsche 09 Jun '08

09 Jun '08

Hi I use deliver with an auth socket I have 2 namespaces (which isn't relevant here, but anyway) namespace private { separator = / prefix = location = maildir:/var/spool/mail/%1n/%2n/%n inbox = YES #hidden = yes } namespace private { separator = / prefix = mail/ location = mbox:/home/%1n/%n/mail inbox = no hidden = no } and also an general mail_location mail_location = maildir:/var/spool/mail/%1n/%2n/%n with deliver 1.0 branch everything works fine with latest deliver 1.1rc8 I get Jun 5 13:32:18 xxx deliver(<username>): mkdir(/var/spool/mail/%1n/%2n/%n/.SPAM/cur) failed: Permission denied looks like arguments don't get resolved kind regards Arne

[Dovecot] v1.1.rc9 released
by Timo Sirainen 09 Jun '08

09 Jun '08

http://dovecot.org/releases/1.1/rc/dovecot-1.1.rc9.tar.gz http://dovecot.org/releases/1.1/rc/dovecot-1.1.rc9.tar.gz.sig Not many bug reports these last few days, so maybe this release will be a good one. + Maildir: When hardlink-copying a file, copy the W=<vsize> in the filename if it exists in the original filename. - mbox: With rc8 empty lines were inserted in the middle of saved mails' headers. - maildir: Fixed problems with opening newly saved messages which we saw in index file but couldn't see in dovecot-uidlist. Happened only when messages weren't saved via Dovecot (deliver or IMAP). - Several bugfixes to handling sort indexes - deliver: Boolean settings that were supposed to default to "yes" were set to "no" unless explicitly defined in dovecot.conf: dotlock_use_excl, maildir_copy_with_hardlinks, mbox_dirty_syncs, mbox_lazy_writes.

Hi, I found a typo on line 101 of dovecot-1.1.rc8/src/lib/failures.c. The first two arguments to io_add() are reversed. The fd should be first, and IO_WRITE second.

Hi. How can I write login name, timestamp and remote host address to MySQL database every time user connects? Now I run a daemon, which "tails" log file and parses output, but maybe that can be done more simply ? -- Dmitry Pryadko http://www.hc.ru

[Dovecot] assertion after upgrading to 1.1rc7 from 1.1rc3
by Nuno Lopes 07 Jun '08

Hi, I'm getting this assertion after making an upgrade from 1.1rc3 to 1.1rc7. Deleting the index files solves the problem. This seems to happen only to some accounts but I haven't managed to find which ones. I'm using dovecot's deliver to deliver the messages.

[Dovecot] question: auth_bind and userdb
by Matthias Šubik 07 Jun '08

07 Jun '08

Hi, this is my first post to the list, I'm not a member, please cc me directly. I'm converting from courier imap, and want to bring a special problem to your attention: I would like to use auth_bind and prefetch, b/c due to data security restriction the user information is only visible to the user himself. From http://wiki.dovecot.org/AuthDatabase/LDAP I found out that pass_attrs only works if no userdn template is set. But when unsetting userdn, dovecot-auth still tries to find the information from pass_attrs before binding. I'm no coding expert so here is my question: would it be possible to make pass_attrs work with userdn? If yes, even prefetch would work. right now, when using userdn, pass_attrs is ignored, but also userdb and user_attrs is impossible for me, because it is done anonymously, it can't reuse the bind from passdb, and can't construct a bind as passdb could. for now I defined a dummy user in ldap, but that's not the ideal solution, since then this dummy user has access to all usernames, uids, uidNumbers and gidNumbers. thank you for your attention best regards matthias subik ps: is there a list of all keywords and parameters?

[Dovecot] quotactl bug?
by JOHN ROMAN 05 Jun '08

05 Jun '08

more on the strange quota error....this is in BSD, with quotas referenced on an NFS, and users provided by YP/NIS quotactl(Q_GETQUOTA, /.amd_mnt/crock/vol/v_user1/jdoe) failed: Operation not supported this looks strange to me, as the specification for quotactl states the function Q_GETQUOTA: Q_GETQUOTA Get disk quota limits and current usage for the user or group (as determined by the command type) with identifier id. The addr argument is a pointer to a struct dqblk structure (defined in <ufs/ufs/quota.h>). this directory path is not a valid UID...rather, its my user home directory path!

[Dovecot] v1.1.rc8 released
by Timo Sirainen 05 Jun '08

05 Jun '08

http://dovecot.org/releases/1.1/rc/dovecot-1.1.rc8.tar.gz http://dovecot.org/releases/1.1/rc/dovecot-1.1.rc8.tar.gz.sig I then decided to add the deliver -c feature to this release. Seems to work in my tests, but who knows if it breaks something.. Although most of the code is called only if -c parameter is given. Anyway we really should have a comprehensive test suite written some day (yes, help is really wanted for this :). So let's hope this is the last RC release. If there aren't any major problems I'll release v1.1.0 in a couple of weeks. I'll also try to merge all my different development trees into a single v1.2 code tree within a few weeks. v1.2.0 will probably be released this summer as well, since it mainly has new features that don't change existing code all that much (CONDSTORE is a bit invasive though). + deliver: Added -c parameter to provide path to delivered mail. This allows maildir to save identical mails to multiple recipients using hard links. - rc6/rc7 broke POP3 with non-Maildir formats - mbox: Saving a message without a body or the end-of-headers line could have caused an assert-crash later. - Several dbox fixes

[Dovecot] Get the size of a maildir
by Nicolas Letellier 05 Jun '08

05 Jun '08

Hello. I would like to know it a 'proper' solution exist to get the size (in MB) of a maildir. Actually, to get it, I do a 'du -sh' but I'm not sure it is a good solution. And it does not return the same value than imap-quota. Is there a command, a tool, in Dovecot to get it? There is the maildirsize but it's very difficult to get the value with a script shell and with this file. Thanks for your help. Best regards, -- - Nicolas.

[Dovecot] FreeBSD port for 1.1, some bits more...
by Geoffroy DESVERNAY 04 Jun '08

04 Jun '08

I did (re-)compile dovecot (1.1rc8) today, with managesieve (0.10.2) and sieve-plugin (1.1.5). I did modify the existing dovecot-devel port, adding managesieve patch as an OPTION, and I added a 'dovecot-managesieve-devel' port, and a 'dovecot-sieve-devel' one to be complete... Not sure everything is very complete, but at least it works for me=E2=84=A2= , and if it can help anybody to save some time... The tree ports are there: http://dgeo.perso.ec-marseille.fr/dovecot Not sure I used the very good way of building FreeBSD ports...

[Dovecot] Re maintenance of the dovecot-uidlist files
by Dann Daggett 04 Jun '08

04 Jun '08

Greetings all, I am new to dovecot, using ver 1.0.13 and IMAP with ~/Maildir delivery. I have noticed that the entries in the dovecot-uidlist files don't seem to get updated when an email is deleted or moved to .Trash. It appears that this list list would just keep growing over time, being full of no longer used filenames, and must tend to increase its processing overhead. I have also noticed that if I manually delete that file and the 3 other dovecot* files, that it gets rebuilt with only what's present. Is there provision in the dovecot code to automatically clean this up periodically? If so, are there any configuration params for it? If not, what is the preferred method for maintenance in this regard? Thank you, Dan

[Dovecot] Error using antispam plugin
by Juan Asensio Sánchez 03 Jun '08

03 Jun '08

Hi When activating antispam plugin in imap protocol, when sending an email, Evolution/Thunderbirdkeeps infinitely "Sending authentication information", and Dovecor logs shows "dovecot: May 28 10:14:35 Error: child 6910 (imap) killed with signal 11"; lots of empty folders in /tmp are created with names like "antispam-mail-ZvyWeZ". I am using Dovecot1.1 rc15 compiled from Debian source repositories (http://xi.rename-it.nl/debian/) and last version of antispam plugin, obtained with git. Any idea or help to debug? Thanks.

03 Jun '08

http://dovecot.org/releases/1.0/dovecot-1.0.14.tar.gz http://dovecot.org/releases/1.0/dovecot-1.0.14.tar.gz.sig Since v1.1.0 release is getting near, this could well be the last v1.0 release. I'll still fix important bugs, but if the bugfix is large or affects only few people it'll probably get fixed only in v1.1 releases. * mbox: Enable mail_privileged_group while creating INBOX. - IMAP: Fixed a rare crash in FETCH BODY/BODYSTRUCTURE - IMAP: If mailbox is selected with EXAMINE, ignore flag changes - proxy: Login success reply was sent in two IP packets, which confused some IMAP/POP3 clients - ACL plugin leaked memory a bit - dovecot-auth: allow_nets setting with network masks didn't work correctly with big endian machines.

[Dovecot] How to set MDNSent flag on a large amount of mails?
by Patrick Nagel 03 Jun '08

03 Jun '08

Hi, after having moved a big mail archive to IMAP, I've now got the following problem: The MUA asks to send an MDN on all those old messages that contain the 'Disposition-Notification-To' header when opened. I'd like to set the $MDNSent flag on those (>10000 in a deeply nested directory structure) mails. After having read http://wiki.dovecot.org/MailboxFormat/Maildir I wrote a script that changed the filename of mails in all directories that contained the header, so that the filename contained a 'b' in the last part of the filename (after the comma), because I found '1 $MDNSent' in Maildir/dovecot-keywords. I then discovered that there can be a 'dovecot-keywords' file in each directory, and all of those files can have different flags in different order. Do I really need to write a script that evaluates each dovecot-keywords file, figures out which letter corresponds to the flag and rename the files (per directory) accordingly? Isn't there a more simple way?

[Dovecot] spamassassin, postfix with dovecot lda?
by George Mamalakis 03 Jun '08

03 Jun '08

Hi all, I am trying to setup a mail server using postfix (virtual_mailboxes), spamassassin and dovecot, along with SQL where appropriate. From my research so far I realized that, for several reasons, it is required for me to use dovecot LDA instead of maildrop, local, procmail or other alternatives. My configuration was working flawlessly, until spamassassin per-user configuration came to play. If I just wanted an MTA anti-spam gateway, I could directly call spamassassin via master.cf, or through some helper "content-filter-application" (like amavis or amavisd-new), and everything would work just fine (I tried and tested many such configurations with success). But when antispam per user preferences became my concern (Bayesian filters and classifier), I realized that spamd should be called by the LDA. With procmail this was a trivial issue, with dovecot-lda I was unable to find any solution on the web or other documentation. So my question is as follows: Is there a way to call spamc from dovecot-LDA (and/or dovecot-sieve), or is there an alternate way to do this for a site with virtual mailboxes configured with dovecot-lda? Thank you all in advance, regards, -- George Mamalakis IT Officer, Department of Electrical and Computer Engineering, Aristotle Univ. of Thessaloniki, Greece

[Dovecot] v1.1.rc6 released
by Timo Sirainen 03 Jun '08

03 Jun '08

http://dovecot.org/releases/1.1/rc/dovecot-1.1.rc6.tar.gz http://dovecot.org/releases/1.1/rc/dovecot-1.1.rc6.tar.gz.sig This is it. The first v1.1 release that actually deserves the "release candidate" name. It contains everything I require from v1.1.0 release. There are two bugs left that I'd like to get fixed, but they won't block v1.1.0 release: * index_mailbox_set_recent_uid() assert (reported by Diego Liziero) * Maildir not always finding new messages and returning them as empty (reported by Anders). The major change in v1.1.rc6 release is the SORT indexing half-rewrite. I hadn't much stress tested that code before, and once I started I just kept finding more and more weird bugs and it became extremely difficult to figure out how to fix them, so I finally decided to just redesign how it's supposed to work and then implemented that. The resulting sort code is a lot cleaner and it should also perform better (although it could still be improved a bit: the basic binary searching could be replaced with one that first binary searches between already-looked-up sort-strings and only after that binary searches the resulting space which requires slower sort-string lookups). Hopefully there are also no stupid bugs left like returning messages in wrong sort order. :) I've been wasting time this past week getting new stuff for my new apartment, but that's nearly done now. I think (hope) I'm going to be more productive in here, there are less neighbours behind walls/floors (just 1), so less potential for annoying noises. :) Thinking also seems to work better when there's more space to walk around. And finally, the changes since v1.1.rc5: * Index file format changed a bit. If an older Dovecot v1.1 reads index files updated by rc6+, they may give "Invalid header record size" or "ext reset: invalid record size" warnings. v1.0 won't give these errors. * IMAP: LIST .. RETURN (X-STATUS) command return now LIST entries before STATUS entries. * zlib plugin: Uncompress if the message begins with zlib header instead of looking at the 'Z' flag. This fixes copying with hard links. Based on a patch by Richard Platel. + IMAP: SORT index handling code was half-rewritten to fix several bugs when multiple sessions were sorting at the same time. The new code is hopefully also faster. + Maildir: If POP3 UIDL extra field is found from dovecot-uidlist, it's used instead of the default UIDL format (or X-UIDL: header). This allows easily preserving UIDLs when migrating from other POP3 servers. Patch by Nicholas Von Hollen @ Mailtrust. + Maildir: ,W=<vsize> is now always added to maildir filenames + deliver: Avoid reading dovecot-uidlist's contents if possible. + Added %T modifier = Trim whitespace from end of string - IMAP: Fixed some bugs in LIST-EXTENDED implementation. - IMAP: If client tries to change the selected mailbox state while another command is still running, wait until the command is finished. This fixes some crashes and other unwanted behavior. - allow_nets userdb setting was broken with big endian CPUs

[Dovecot] overview of patches used in Fedora
by Dan Horák 03 Jun '08

03 Jun '08

Hi, I have gone through the patches that are used in the Fedora package and probably only the "mkcert-permissions" [1] can be considered to be included upstream. It is dated into package version 1.0-0.beta2.3, but I cannot find any particular reason for the inclusion (like a bug in bugzilla, etc.). Some (winbind support, quota warnings) were obsoleted by dovecot 1.1, two are used for distro specific settings. So the only real patch that remains is the "pam_setcred" [2] patch that fixes https://bugzilla.redhat.com/show_bug.cgi?id=146198 Current state of the package for Fedora is at http://cvs.fedoraproject.org/viewcvs/rpms/dovecot/devel/ Dan [1] http://cvs.fedoraproject.org/viewcvs/rpms/dovecot/devel/dovecot-1.0.beta2-m… [2] http://cvs.fedoraproject.org/viewcvs/rpms/dovecot/devel/dovecot-1.0.rc2-pam… -- Fedora and Red Hat package maintainer

[Dovecot] Unsuccessful POP sessions on dovecot-1.0.3-13_60
by Patrick Ben Koetter 03 Jun '08

03 Jun '08

A Client runs a RAS network. Users access mailboxes using Outlook Express. The server runs dovecot-1.0.3-13_60. Almost a week ago users began to report that they can't retrieve their mail. The session starts, they seem to retrieve messages, but then the client reports a problem and the session is terminated. Here's what I have in the log: May 28 08:56:46 server dovecot: pop3-login: Login: user=<user@client>, method=PLAIN, rip=::ffff:10.11.9.18, lip=::ffff:10.11.9.108 May 28 08:59:00 server dovecot: POP3(user@client): Disconnected top=0/0, retr=5/448621, del=0/58, size=8991962 May 28 08:59:29 server dovecot: pop3-login: Login: user=<user@client>, method=PLAIN, rip=::ffff:10.11.9.18, lip=::ffff:10.11.9.108 May 28 09:03:49 server dovecot: POP3(user@client): Disconnected top=0/0, retr=5/448621, del=0/58, size=8991962 May 28 09:04:24 server dovecot: pop3-login: Login: user=<user@client>, method=PLAIN, rip=::ffff:10.11.9.18, lip=::ffff:10.11.9.108 May 28 09:12:11 server dovecot: POP3(user@client): Disconnected top=0/0, retr=5/448621, del=0/58, size=8991962 May 28 09:14:32 server dovecot: pop3-login: Login: user=<user@client>, method=PLAIN, rip=::ffff:10.11.9.18, lip=::ffff:10.11.9.108 May 28 09:17:10 server dovecot: POP3(user@client): Disconnected top=0/0, retr=5/448621, del=0/58, size=8991962 May 28 09:17:52 server dovecot: pop3-login: Login: user=<user@client>, method=PLAIN, rip=::ffff:10.11.9.18, lip=::ffff:10.11.9.108 May 28 09:20:27 server dovecot: POP3(user@client): Disconnected top=0/0, retr=5/448621, del=0/58, size=8991962 May 28 09:23:23 server dovecot: pop3-login: Login: user=<user@client>, method=PLAIN, rip=::ffff:10.11.9.18, lip=::ffff:10.11.9.108 May 28 09:30:05 server dovecot: POP3(user@client): Disconnected top=0/0, retr=5/448621, del=0/58, size=8991962 What I see is that the client seems to try to retrieve the same mails (retr=5/448621) over and over again. If they login using IMAP they don't experience any problems. Any idea what this could be? Rumor has it it's a know problem with Outlook Express and its POP implementation.

[Dovecot] Purging Deleted Messages
by Carlos Williams 02 Jun '08

02 Jun '08

I noticed today I checked a users mailbox with the mutt command: mutt -f /home/bob/email/ There I saw he had 100 messages that had been deleted but not yet purged from his inbox so they're still using up disk storage on my email server. My question is does Dovecot have a process to automatically delete these messages after a certain period of time? I would like to think that they don't just sit in a users mailbox for years waiting to be purged, right? Does anyone know exactly how this works? I checked my own mailbox using mutt and I see 11 messages that are deleted from my Thunderbird client but are still on the server (marked for deletion). How long do these messages stay there? -- Man your battle stations...

Hi We're in the phase of converting our existing unix-based users to virtual users. Goal is to make mail-spool totaly independent of home-spool. For that reason, NO files can be written to home. I've solved the problem for all files, except for .dovecot.lda-dupes. I can see in duplicate.c #define DUPLICATE_PATH "~/.dovecot.lda-dupes" I thought being clever and override in the userdb passwd following args = home=/var/spool/mail/%1n/%2n/%n but deliver totaly ignores that. does anybody has tips? kind regards Arne

[Dovecot] deliver saving mails with hard linking
by Timo Sirainen 02 Jun '08

02 Jun '08

http://dovecot.org/tmp/deliver-multiple.diff for Dovecot v1.1 implements -p <path> parameter for deliver, which reads the input mail from the specified path instead of stdin. With maildir and hardlink copying enabled, it also tries to hard link the file to destination instead of copying it. So to get the same mail delivered to multiple recipients using hard links, you'd have to write a small wrapper script that stored the mail temporarily somewhere and then called deliver for each recipient using the -p parameter. Any thoughts on if this should go to v1.1 like this? Some problems: - If you're not using a single UID/GID you probably have to make the file world-readable. - A wrapper script is kind of ugly, so it would be nice if deliver took a list of all recipients as input. But the deliver code is currently ugly enough that this would require larger changes. - Am I forgetting something?..

Why did I fail to mention that I was trying to use uiddb from Courier? :P Using your conversion script fixed it, but simply copying the Courier file crashed Dovecot. According to http://wiki.dovecot.org/Migration/Courier this is supposed to work though, so either that page is wrong, or Dovecot has a bug. >> betty - ~vpopmail/domains/bar.com/foo # gdb /usr/lib/dovecot/imap core > .. >> (no debugging symbols found) >> Core was generated by `imap'. >> Program terminated with signal 11, Segmentation fault. >> #0 0x080a539d in imap_bodystructure_write () >> (gdb) bt full >> #0 0x080a539d in imap_bodystructure_write () >> No symbol table info available. >> #1 0x08083b5c in ??

Right. This isn't implemented yet. Also I don't think it should rely on Message-ID: header proving the uniqueness. There are two ways this can be implemented reliably: 1) If the message is sent to multiple recipients using same RCPT TO command, all the recipients could be given to deliver as parameters, and deliver would know that it's the same message and they could be hard linked. 2) Keep some kind of a hash database where hash is e.g. SHA1 sum of the entire message. All messages could be then stored in some global directory and hard linked from there to users' mailboxes. When receiving a new message using an existing hash, it could still compare byte-by-byte the files to make sure that it's not a hash collision before hard linking the file. 1) probably wouldn't be too difficult to implement and probably would solve your problem (assuming the problem is that people are mailing 100MB attachments to everyone inside a company). But I don't think I have time to do it myself..

[Dovecot] Dovecot hard link problem
by 도원철 01 Jun '08

01 Jun '08

My company recently changed mail server from cyrus to dovecot. The problem is that dovecot does not support hard links for message files with same message ID. I turned on the ‘maildir_copy_with_hardlinks’ option in dovecot.conf, but it does not seems to have relation to this problem, am I misunderstood? Hard links are created when move or copy messages from one folder to other folder, but when deliver creates messages this option does not works. Our mail storage will be exhausted in few days. If you have some idea to solve this problem, please please help me. Or If you fix this problem, I will happily pay for it at reasonable cost. I installed dovecot 1.0.13 and postfix 2.5.1.

[Dovecot] Segfault in imap_bodystructure_write when searching

Whenever I try to search on my dovecot test install, dovecot dies. It immediately spawns a new process, which the client tries to connect to, and send search commands to, causing that to die, and so forth. This loop means I have to kill either the server or the client. Running Dovecot 1.0.13 from/on Debian testing, rebuilt with vpopmail support and no other source changes. Vpopmail version is 5.4.25, latest stable. Client is Mulberry 4.0.8, and the crash seems to occur whenever any type of search is performed, be it subject, sender, body etc. Otherwise the server behaves fine. dovecot -n output: # 1.0.13: /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S listen: *:9000 disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login login_greeting_capability: yes login_max_processes_count: 256 first_valid_uid: 89 mail_location: maildir:~/Maildir mail_debug: yes dotlock_use_excl: yes maildir_copy_with_hardlinks: yes maildir_copy_preserve_filename: yes mail_drop_priv_before_exec: yes mail_plugins: quota imap_quota imap_client_workarounds: outlook-idle delay-newmail auth default: user: vpopmail verbose: yes passdb: driver: vpopmail userdb: driver: vpopmail plugin: quota: maildir Anonymized log excerpt: May 31 21:01:24 betty dovecot: imap-login: Login: user=<foo(a)bar.com>, method=PLAIN, rip=1.2.3.4, lip=4.3.2.1 May 31 21:01:24 betty dovecot: child 21748 (imap) killed with signal 11 May 31 21:01:24 betty dovecot: imap-login: Login: user=<foo(a)bar.com>, method=PLAIN, rip=1.2.3.4, lip=4.3.2.1 May 31 21:01:24 betty dovecot: child 21752 (imap) killed with signal 11 May 31 21:01:24 betty dovecot: imap-login: Login: user=<foo(a)bar.com>, method=PLAIN, rip=1.2.3.4, lip=4.3.2.1 May 31 21:01:25 betty dovecot: child 21753 (imap) killed with signal 11 May 31 21:01:25 betty dovecot: imap-login: Login: user=<foo(a)bar.com>, method=PLAIN, rip=1.2.3.4, lip=4.3.2.1 May 31 21:01:25 betty dovecot: child 21759 (imap) killed with signal 11 May 31 21:01:25 betty dovecot: imap-login: Login: user=<foo(a)bar.com>, method=PLAIN, rip=1.2.3.4, lip=4.3.2.1 May 31 21:01:25 betty dovecot: child 21774 (imap) killed with signal 11 May 31 21:01:25 betty dovecot: imap-login: Login: user=<foo(a)bar.com>, method=PLAIN, rip=1.2.3.4, lip=4.3.2.1 May 31 21:01:25 betty dovecot: child 21775 (imap) killed with signal 11 May 31 21:01:25 betty dovecot: imap-login: Login: user=<foo(a)bar.com>, method=PLAIN, rip=1.2.3.4, lip=4.3.2.1 May 31 21:01:25 betty dovecot: child 21776 (imap) killed with signal 11 ...

[Dovecot] fetchmail on demand
by Graeme Vetterlein 31 May '08

31 May '08

I hoping this is an RTFM ... and somebody can point me at the correct 'FM' :-) I've just spent a while setting my new Debian , allways-on box in what I suspect is a generally useful configuration. I have fetchmail(1) collect mail from many mailboxes via pop3. I store these mails in different mboxs according to rules in procmail(1) I then offer these out to the household via imap in dovecot(1) . I have fetchmail(1) set to poll the ISPs every 5 minutes, this seems to work fine, but there are two issues: 1: The constant polling keeps the disk spinning for no good reason (most of the time) 2: If I check my mail via a mail reader using imap to the local mboxes ...there could be mail sitting on the ISP servers I don't see (for 5 mins) Now what would be much nicer, would simply be to have dovecot(1) issue the fetchmail(1) command whenever it it got an imap request. I general what I guess I would like is: "When a request comes in (via imap) fork off a command who's name is given in the conf file. ... imap_pre_cmd="xxx" -- Graeme

[Dovecot] Web-based shared calendar synchronizable with Outlook
by Samuel HAMEAU 30 May '08

30 May '08

Hi, I know this request is a a little off-topic but may be interesting for dovecot users (at least i hope!) Does anybody has already had an experience with a calendar sharing solution including a webcalendar and an outlook connector, "compatible" with dovecot ? Today, there are many projects aiming to be a "M$ Exchange Killer" (such as Zimbra, OBM, open-exchange, etc) but they offers a global package with MTA and imap server included. I saw the page about BynariConnector (http://wiki.dovecot.org/HowTo/BynariConnector) but unfortunatly they do not provide a webmail :( I'm afraid What I am looking for is a shared agenda solution providing a webcalendar, an outlook connector and eventually a pda connector, using (or not) dovecot, and a corporate ldap server... What are you guys using ? sam

[Dovecot] no bookeeping using public folders
by Claude Frantz 30 May '08

30 May '08

Using dovecot 1.0.10. In the config: namespace public { separator = / hidden = no prefix = Flock/ location = maildir:/home/baratin/PublicMaildir:CONTROL=~/Maildir/control/Flock:INDEX=/var/dovecot/index/%u/Flock } This should be a public mail folder owned by "baratin", "read only" for all other users. Every user has his/her own control and index area related to this public folder. I have verified, they are owner and "group" of the respective control and index area. The problem, while using Thunderbird: The "read only" user can delete messages or mark then read. But after a new session, all the messages are still "new". Of course, only "baratin" is the owner. The problem, while using mutt and IMAP: mutt refuse to change any flag because the folder is "read only". Of course, this is correct. My question: Why is no bookkeeping maintained for "other" users, although every one has his/her own control and index structure ? Thanks a lot ! Claude

[Dovecot] Problem deleting folders with Thunderbird?

I am running Thunderbird 2.0.0.14 on Windows XP. When I try to delete one of the folders I get a dialog with the following "The current command did not succeed. The mail server responded: Target mailbox doesn't allow inferior mailboxes." I am running dovecot version 1.0.13-6.fc8 under Fedora 8. The output of dovecot -n is below; [root@www knute]# dovecot -n # 1.0.13: /etc/dovecot.conf protocols: imaps pop3s disable_plaintext_auth: yes 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_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 auth default: passdb: driver: pam userdb: driver: passwd Is there something to be configured to allow mail box deletion?

[Dovecot] dovecot's deliver and SELinux
by Dan Horák 29 May '08

29 May '08

Hello, I am the new maintainer of dovecot for Fedora and Red Hat and so I am trying to cleanup some old reported bugs. One of them is a problem when "deliver" writes of temporary files into /tmp are blocked by SELinux policy (https://bugzilla.redhat.com/show_bug.cgi?id=424091) From the SELinux's point of view it is bad when system services try to write into /tmp (for detail see http://danwalsh.livejournal.com/11467.html) The solution looks simple - just to switch from /tmp to PKG_RUNDIR (line 472 in deliver.c for dovecot 1.0) for writing the temp files. But this raises two questions - will it really work and when yes, is it acceptable for the author? Thanks, Dan -- Fedora and Red Hat package maintainer

[Dovecot] Trim trailing whitespace from username
by David Jonas 29 May '08

29 May '08

Recently we changed Postfix to use Dovecot for our SASL authentication and we ran into trouble with some of our clients having extraneous spaces at the end of their usernames. The quick fix was to add a space to username_chars. The slightly longer fix was a pretty simple patch to Dovecot. I put the trimming in auth_request_fix_username. I didn't think it warranted a full strfuncs function. If there is a better way to do this I'm all ears. I don't really like patching with my own code, even if I did essentially steal if from the kernel's strstrip(). diff -u dovecot-1.1.rc5/src/auth/auth-request.c dovecot-1.1.rc5-patched/src/auth/auth-request.c --- dovecot-1.1.rc5/src/auth/auth-request.c 2008-05-04 15:01:52.000000000 -0700 +++ dovecot-1.1.rc5-patched/src/auth/auth-request.c 2008-05-16 00:44:15.000000000 -0700 @@ -22,6 +22,7 @@ #include <stdlib.h> #include <sys/stat.h> +#include <ctype.h> struct auth_request * auth_request_new(struct auth *auth, const struct mech_module *mech, @@ -750,6 +751,7 @@ { unsigned char *p; char *user; + size_t size; if (strchr(username, '@') == NULL && request->auth->default_realm != NULL) { @@ -759,6 +761,16 @@ user = p_strdup(request->pool, username); } + /* Trim trailing whitespace from the username */ + size = strlen((unsigned char*)user); + if(size) { + p = user + size - 1; + while (p != user && isspace(*p)) + p--; + *(p + 1) = '\0'; + p = NULL; + } + for (p = (unsigned char *)user; *p != '\0'; p++) { if (request->auth->username_translation[*p & 0xff] != 0) *p = request->auth->username_translation[*p & 0xff];

[Dovecot] Sieve/Vacation
by Ulrich Schreiner 29 May '08

29 May '08

hi, i'm using 1.1.rc5 but the same error occured with 1.0.13. the dovecot package was installed on centos 5 with rpm's from atrpms. exim 4.69. everything works fine except the vacation's from sieve. don't get me wrong, sieve works for everything, including mailforwards, or sorting in subfolders. but when i have a vacation, the script is compiled, but it produces the following output: sieve_execute_bytecode(/var/virtuser/test@<adomain>.sievec) failed (the "<adomain>" is replaced with the real domain of the user). i use virtual users in different domains. the sieve-scripts are generated by horde/ingo and stored via ftp in the "/var/virtuser" directory with the pattern "%u.sieve". the "sievec" files are up-to-date, because: a) i can delete the "sievec" files and they are regenerated b) i can "sieved" them and get an disassembled output with the vacation rule inside but when executing the script (when a mail arrives) the upper error is logged and no vacation is processed. the same error occured with 1.0.13 thank you </usc>

[Dovecot] Dovecot 1.0 rc15 + Quota by user using mysql
by Lucas Carlessi 28 May '08

28 May '08

Hi all, I installed the Dovecot on a Debian by apt-get, it's all working except quota by user.. I have a database with all quotas in bytes, and that lines in /etc/dovecot/dovecot-sql.conf : driver = mysql connect = host=127.0.0.1 dbname=mailserver user=USER password=PASS default_pass_scheme = CRYPT password_query = SELECT email as user, password FROM view_users WHERE email='%u'; #Quota: user_query = SELECT home AS maildir, 5000 AS uid, 5000 AS gid, CONCAT('dirsize:storage=', ROUND( view_users.quota / 1024) ) AS quota FROM view_users WHERE email='%u'; and in /etc/dovecot/dovecot.conf : protocol imap { mail_plugins = quota imap_quota } protocol pop3 { pop3_uidl_format = %08Xu%08Xv mail_plugins = quota } plugin { #quota = maildir:ignore=Trash } But when I open the webmail I have no limit quotas! If I put quota = maildir:storage=101480 in plugin the quota works fine at 100MB, but in all users... Is the query right? There is another way to configure quotas by user in Dovecot 1.0 using mysql? Sorry my bad English, and thank you all!

[Dovecot] Vanishing maildirsize files with 1.0.7 using 'deliver' via postfix
by Jason Forester 28 May '08

28 May '08

Aloha, I've searched the list and have found no similar reports, so I'm asking here. We have 3 RH5.1 boxes running the stock Postfix 2.3.3, but due to issues with the stock Dovecot 1.0rc15, Redhat supplied us with the version of Dovecot 1.0.7 that will be in Redhat 5.2. The mail store is automounted per-user from a Sun box via NFS. We were using it with no problems until last Friday, when we attempted to implement quotas. I had done quite a lot of testing on a single system, so I didn't anticipate any issues here. I created maildirsize files for each user in the NFS-mounted /var/spool/mail/$USER and everything seemed fine. I changed mailbox_command to /usr/libexec/dovecot/deliver in postfix main.cf. Mail was delivered, quota files updated, all good. However almost immediately a maildirsize folder vanished. Soon after another, then another, and now we're missing nearly 40 of them. Any ideas as to why they're vanishing? Something to do with NFS? I've tried to trigger it by massively sending to the same user on all three systems but have yet to reproduce it at will. Any clues would be appreciated. For reasons of support I cannot upgrade to a later dovecot at this time. Best Regards, - jason

[Dovecot] Dovecot quota for mailadministrator
by Markus Hofer 27 May '08

27 May '08

Hallo, i have a question for the quota with dovecot. I plan to go from our cyrus installation to dovecot. I have just install dovecot without problem with mysqldb and quota per user. Quota work well and the user receive always via Webmail or client the quota information. My question is: With cyrus the mailadministrator has the possibility to see the quota for all users with the command "quota". Output or example: 300000 9 28305 user.tinfo With that way the administrator could have always a look if some users have quota problems. My question is, if dovecot has some similar command for the administrator? Thanks in advance. Markus

[Dovecot] Problem with checkpassword-reply
by sawyer x 27 May '08

27 May '08

Hello I posted an earlier post on problems with getting usernames. That one is solved, thank you. I'm currently having trouble executing checkpassword-reply. The maillog shows the following error: (substituting rip/lip/user/domain) May 27 07:21:06 saw dovecot: Logins with UID 0 not permitted (user user(a)domain.com> May 27 07:21:06 saw dovecot: imap-login: Internal login failure: user=<user(a)domain.com>, method=plain, rip=xxx.xxx.xxx.xxx, lip=xxx.xxx.xxx.xxx, TLS My script reads fd3 right and gets all the details correct. Then runs the following code: --- $REPLY = $ARGV[0] || exit 111; # this is actually run much earlier $ENV{HOME} = "$USERSHOME/$domain/$user"; $ENV{USER} = $user; # effective gid $) = 300; # effective uid $> = 300; exec $REPLY; --- I've looked at the checkpassword-reply code (thank god for open source software) and I saw that it opens fd4 for writing. I couldn't find any documentation about this and couldn't find anyone who is using checkpassword-reply. No sample scripts, no examples, and the documentation on the site is extremely scarce. The wiki docs indicate I should just execute it - which I do - but that does not help. Also, the debugging isn't very meaningful. I'm definitely changing the UID and GID, but it's not apparent in the maillog. The fie permissions on checkpassword-reply show I could execute it under any user and I've tried that with "sudo -u <user> /path/to/checkpassword-reply. On a post somewhere in the vortex of the internet someone said Dovecot does not allow any uid/gid under 99 (which is why I tried 300), but I couldn't find any documentation for that anywhere in the wiki either. What am I missing and is there anything I've missed that would have prevented me from emailing the mailing list with this long email? Thanks, Sawyer.

[Dovecot] mbox From escaping implementation ?
by Nicolas KOWALSKI 27 May '08

27 May '08

Hello, I read in the wiki (http://wiki.dovecot.org/MailboxFormat/mbox) about "From Escaping": "Dovecot doesn't currently do this escaping however. Instead it prevents this confusion by adding Content-Length headers so it knows later where the next message begins. Dovecot doesn't either remove the '>' characters before sending the data to clients. Both of these will probably be implemented later." As I understand it, this makes the mbox format of dovecot slightly incompatible with other mbox-capable clients, because if they read the data files directly, they may understand a line starting with an unescaped 'From ' as the start of a new message. Right ? Are there any plans to implement this escaping in the future (1.1.x or 2.0.x?) Thanks, -- Nicolas

[Dovecot] Sieve plugin changes 'To' header on redirect
by Patrick Nagel 27 May '08

27 May '08

Hi, I'm a bit confused by the fact that the 'To' header is being modified by sieve when a message is being redirected. RFC3028 states in chapter 4.3: > The "redirect" action is used to send the message to another user at > a supplied address, as a mail forwarding feature does. The > "redirect" action makes no changes to the message body or existing > headers, but it may add new headers. The "redirect" modifies the > envelope recipient. (see http://www.ietf.org/rfc/rfc3028.txt) The situation here is as follows: I'm sending a mail to "city(a)company.net" (To: ...), which is being delivered to "city(a)city.company.net" (Delivered-To: ...). User city has the following sieve script: redirect "other(a)company.net"; keep; One would expect, that the 'To:' header is identical in both mails, but instead I get something like this: Mail in 'city' mailbox: > Delivered-To: city(a)city.company.net > To: city(a)company.net > Subject: test mail (Redirected) Mail in 'other' mailbox: > Delivered-To: other(a)city.company.net > To: city(a)city.company.net > Subject: test mail It seems as if sieve uses the 'Delivered-To' header as the 'To' header in the redirected mail - which is not what I need. Am I misunderstanding something here, or does dovecot's sieve plugin not act according to the RFC?

[Dovecot] Bug: subscriptions file does not take on the same perms as dovecot-shared
by Damon Atkins 27 May '08

27 May '08

All, Version: 1.1.rc5 Solaris x86 on ZFS Shared Folder Bug, renamed a folder with sub folders (Maildir format) After the rename the subscriptions file is own by the person who renamed the folders, and access is owner rw only. Instead it should be the same as dovecot-shared which would general be rw owner, and rw group for a shared folder. Cheers Damon.

[Dovecot] Multiple files for sieve
by Adrián Ribao Martínez 27 May '08

27 May '08

Hello, I have this line in the plugins configuration section : sieve = /etc/dovecot/sieve Where: /etc/dovecot/sieve: require "fileinto" if header :contains "Subject" "****SPAM****"{ fileinto "spam"; } I want this filter for all the users of the system, but I also want to tell dovecot to look in the /home/user/mail/.sieve file for custom per-user filters. Can I do this? Thank you. -- Adrián Ribao Martínez

[Dovecot] Dovecot crash in 1.0.9
by Peter Eriksson 26 May '08

26 May '08

I've been having a problem with a crashing Dovecot the last couple of months where it crashes after a couple of weeks of uptime. Been a bit difficult to diagnose. Anyway, we're now running 1.0.9 on a Sun Fire T1000 running Solaris 10. Any good ideas on how to pin-point the problem? - Peter Here's the output from syslog when the last crash happened: May 14 11:46:50 ifm.liu.se dovecot: [ID 107833 mail.info] imap-login: Login: user=<hidta>, method=PLAIN, rip=130.236.160.20, lip=13 0.236.160.6, secured May 14 11:46:50 ifm.liu.se dovecot: [ID 107833 mail.info] auth(default): new auth connection: pid=4054 May 14 11:46:51 ifm.liu.se dovecot: [ID 107833 mail.error] IMAP(joher): file maildir-uidlist.c: line 143: assertion failed: (UIDLIS T_IS_LOCKED(uidlist)) May 14 11:46:51 ifm.liu.se dovecot: [ID 107833 mail.error] IMAP(joher): Raw backtrace: 0x100082768 -> 0x1000298ec -> 0x100027e70 -> 0x100028fa8 -> 0x1000294a8 -> 0x10002057c -> 0x100014824 -> 0x100016cb4 -> 0x1000170d4 -> 0x10008a458 -> 0x100089938 -> 0x100022ad 8 -> 0x10000fe7c May 14 11:46:51 ifm.liu.se dovecot: [ID 684838 mail.error] child 3677 (imap) killed with signal 6 May 14 11:46:51 ifm.liu.se dovecot: [ID 107833 mail.warning] IMAP(hidta): Killed with signal 15 May 14 11:46:51 ifm.liu.se dovecot: [ID 107833 mail.warning] IMAP(peber): Killed with signal 15 ...

[Dovecot] Sort output of dovecot -n alphabetically?
by Charles Marcus 25 May '08

25 May '08

Is there a way? Postfix does this by default, and it makes it much less likely to miss/overlook a setting... If there is no way, any chance to modify it so that it does? Thanks for dovecot! Really looking forward to 1.1 release! -- Best regards, Charles

[Dovecot] dovecot developer documentation
by Piotr Wadas 25 May '08

25 May '08

Hello, I want to create some specific plugin for dovecot v1.1 (rc5). Where can I find some developer documentation ? Can I build my plugin separately, or do I need to rebuild dovecot again ? I'm looking into code, and analyzing some simple plugins, but hooks documentation or any hints you could give would be very helpful.. AFAIK there's no search for mailing list archives available, to let me search for some older guidance in this case :( Regards, Piotr

[Dovecot] Error while set mailQuota=0 with mbox and LDAP backend
by Zhang Huangbin 25 May '08

Hi, all. I have OpenLDAP(+qmail.schema), Dovecot, Postfix installed on RHEL 5.1 (x86_64), and they works fine with mbox format. The problem is if i set 'mailQuota=0' in LDAP, postfix can't send mail to recipient user. But it works fine with 'mailQuota != 0', such as '10240'(10M). What's wrong with my mail server setting? How can i solved this issue? Thanks very much.

[Dovecot] Auto-subscribe to folders
by Juan Asensio Sánchez 25 May '08

25 May '08

Hi I will use autocreate plugin in a new installation, and client has asked me if the users can be auto-subscribed to certain folders. Example: the users will have an autocreated Junk folder (for SPAM) and we want the users not to be un-subscribed for this folder; so if the user wants to be unsubscribed (from outlook, webmail, etc), there are two options: a) the action is rejected or denied; b) the next time he/she logins, then the folder is autosubscribed again. Could this be done? How? Thanks in advance.

[Dovecot] Domain variable in checkpassword
by sawyer x 25 May '08

25 May '08

Hello everyone I'm using the checkpassword method but I don't get the domain a user inputs. I can't cross check per virtual domains if I'm not getting one, which means it renders all my efforts useless. I've tried sending %d as a variable to my checkpassword script, but I'm just getting %d instead. This is a dump of my information: %ENV = { 'USERNAME_TRANSLATION' => '', 'SYSLOG_FACILITY' => '16', 'CACHE_SIZE' => '0', 'RESTRICT_GID_LAST' => '', 'TCPREMOTEIP' => '213.31.43.3', 'RESTRICT_GID_FIRST' => '', 'AUTH_NAME' => 'default', 'CACHE_TTL' => '3600', 'SERVICE' => 'IMAP', 'USERDB_1_DRIVER' => 'prefetch', 'USERNAME_CHARS' => 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@', 'DOVECOT_MASTER' => '1', 'RESTRICT_SETGID' => '', 'AUTH_WORKER_MAX_COUNT' => '30', 'AUTH_WORKER_PATH' => '/var/run/dovecot/auth-worker.25291', 'PASSDB_2_ARGS' => '/etc/exim/checkp %d', 'USERNAME_FORMAT' => '', 'LOCAL_IP' => '128.177.27.100', 'PASSDB_2_DRIVER' => 'checkpassword', 'PASSDB_1_DRIVER' => 'pam', 'REALMS' => '', 'PROTO' => 'TCP', 'ANONYMOUS_USERNAME' => 'anonymous', 'RESTRICT_SETEXTRAGROUPS' => '', 'TCPLOCALIP' => '128.177.27.100', 'LOG_TO_MASTER' => '1', 'MASTER_USER_SEPARATOR' => '', 'RESTRICT_SETUID' => '', 'REMOTE_IP' => '213.31.43.3', 'RESTRICT_USER' => '', 'DOVECOT_VERSION' => '1.0.rc15', 'MECHANISMS' => 'plain', 'RESTRICT_CHROOT' => '', 'DEFAULT_REALM' => '' }; ARGS: @ARGV = [ '%d', '/usr/libexec/dovecot/checkpassword-reply' ]; Thanks, Sawyer.

First, thanks for this great product. We migrated from Courier last week with only small bumps along the way. We have a few hundred active users with a mix of pop3 and imap clients. The server is running on sparc Solaris 9. We're seeing a problem now with the number of "imap-login" processes rising slowly to it's limit and then (understandably) not letting any more logins happen. Legitimate users seem to have no problem logging in until the limit is hit. Another odd thing is that this is not a problem for pop3-login processes, just imap... I've tried changing some obvious things including the passdb from pam to passwd and back again, but here's the current dovecot -n output: # 1.0.13: /opt/dovecot/etc/dovecot.conf protocols: imap imaps pop3 pop3s ssl_cert_file: /opt/dovecot/etc/ssl/certs/dovecot.pem ssl_key_file: /opt/dovecot/etc/ssl/certs/key.pem disable_plaintext_auth: no login_dir: /opt/dovecot/var/run/dovecot/login login_executable(default): /opt/dovecot/libexec/dovecot/imap-login login_executable(imap): /opt/dovecot/libexec/dovecot/imap-login login_executable(pop3): /opt/dovecot/libexec/dovecot/pop3-login login_processes_count: 12 login_max_processes_count: 512 verbose_proctitle: yes mail_location: maildir:~/Maildir mmap_disable: yes mail_executable(default): /opt/dovecot/libexec/dovecot/imap mail_executable(imap): /opt/dovecot/libexec/dovecot/imap mail_executable(pop3): /opt/dovecot/libexec/dovecot/pop3 mail_plugin_dir(default): /opt/dovecot/lib/dovecot/imap mail_plugin_dir(imap): /opt/dovecot/lib/dovecot/imap mail_plugin_dir(pop3): /opt/dovecot/lib/dovecot/pop3 pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv namespace: type: private prefix: INBOX. inbox: yes auth default: verbose: yes passdb: driver: pam userdb: driver: passwd Any ideas or advice?

[Dovecot] Bug [1.1rc5]: Crash during "CPU architecture changed" index upgrade

[Dovecot] Maildir locking by LDA of dovecot
by Mike Grozak 25 May '08

25 May '08

Hi all! First of all, I want ti thank the whole Dovecot community (developers for developing and fast responses, users for populating and responses too). Dovecot is a really good and fast IMAP server - it serves near 3000 in our installation. Now I have a problem and request community's help its resolving;) Dovecot version: 1.0.13, compiled with vpopmail support. I have an account spam(a)domain.com (:-), in which we put all our spam (we gather statistic later). There can be 10 and more delivery attempts in a second to maildir of this account during the spam attacks on our server. The queue of our server can grow up to 20k messages, and all of these messages are sent to spam(a)domain.com. I found a lot of such strings in dovecot.log file during such DoS attack: dovecot.log:deliver(spam@domain.com): May 16 04:18:48 Info: msgid=<01c8b6da$a8bacf80$b7af2abe@sale>: save failed to INBOX: Timeout while waiting for lock dovecot.log:deliver(spam@domain.com): May 16 04:18:59 Info: msgid=<6611811842.20080516012444(a)poiusadfhnvxzmdiasdasgkhlsdkfg.com>: save failed to INBOX: Timeout while waiting for lock dovecot.log:deliver(spam@domain.com): May 16 04:20:06 Info: msgid=<01c8b6a8$7b552e00$a0a4034c@sale>: save failed to INBOX: Timeout while waiting for lock dovecot.log:deliver(spam@domain.com): May 16 04:20:14 Info: msgid=<360825920.32055246029506(a)mirgames.ru>: save failed to INBOX: Timeout while waiting for lock dovecot.log:deliver(spam@domain.com): May 16 04:20:50 Info: msgid=<01c8b6b1$0df9cb00$cc36dfc9@tek2>: save failed to INBOX: Timeout while waiting for lock dovecot.log:deliver(spam@domain.com): May 16 04:21:00 Info: msgid=<087901c7ca2d$ef272640$1e01a8c0(a)telefonia.InterCable.net>: save failed to INBOX: Timeout while waiting for lock dovecot.log:deliver(spam@domain.com): May 16 04:21:01 Info: msgid=<000701c8b6d2$01ff999f$c491aca7@snoueiij>: save failed to INBOX: Timeout while waiting for lock dovecot.log:deliver(spam@domain.com): May 16 04:22:32 Info: msgid=<000801c8b69b$060c0230$3cd8a4b7@cpbvlrx>: save failed to INBOX: Timeout while waiting for lock dovecot.log:deliver(spam@domain.com): May 16 04:22:45 Info: msgid=<000801c8b6a5$04ba6412$9910848d@aldldr>: save failed to INBOX: Timeout while waiting for lock dovecot.log:deliver(spam@domain.com): May 16 04:22:45 Info: msgid=<031401c772e2$adc5be40$1e01a8c0(a)mtu-net.ru>: save failed to INBOX: Timeout while waiting for lock dovecot.log:deliver(spam@domain.com): May 16 04:23:08 Info: msgid=<01c8b6db$0222fe80$b7af2abe@info>: save failed to INBOX: Timeout while waiting for lock What can I do for resolving this locks?

[Dovecot] Multiple private namespace question
by Troy Engel 24 May '08

24 May '08

(apologies if this has been covered, can't find it on the Wiki/FAQ, etc.) We have a stellar, fantastic, hard working Dovecot 1.0.5 (yes, I need to upgrade) installation running in Courier-IMAP compatibility mode: mail_location = maildir:~/Maildir:INDEX=/var/spool/dovecot/indexes/%1u/%u namespace private { separator = . prefix = INBOX. inbox = yes } A user purchased a Windows Mobile 6 device which is ignoring the namespace (it's the device's bug for sure, other people report it on forums around the 'net) and there's no way on this device to manually set the Prefix; so, his Sent mails are never making it back to the server when replying from the device because of the missing INBOX. issue. Can I add a second hidden namespace with no prefix: namespace private { separator = . prefix = hidden = yes } ...to fix his problem, but without adversely affecting anyone else? The issue that has given me pause is this comment in the config file: "Default namespace is simply done by having a namespace with empty prefix." ..but then there's also: "If namespace is hidden, it's not advertised to clients via NAMESPACE extension or shown in LIST replies." I'm not sure what exactly will happen by adding a hidden namespace with no prefix after an advertised namespace with a prefix; this is a live server, so mucking up the works with a bad config is not an option. :) Anyone have a clue if this is valid/good/correct and Dovecot will play nicely? Many thanks, -te -- Troy Engel | Systems Engineer Fluid, Inc | http://www.fluid.com

[Dovecot] I've moved
by Timo Sirainen 24 May '08

24 May '08

I've moved again. If you need to know my new address, whois imapwiki.org (dovecot.org address is still lagging behind). My living costs also increased some because of this, but hopefully I'll get enough money from Dovecot coding to pay for it. :) I'll try to get back to replying mails within the next few days.

[Dovecot] Disallow folder delete
by Kenneth Porter 24 May '08

24 May '08

Is there a straightforward way to disallow the deletion of all IMAP mailboxes? I have a user who's deleted an important IMAP mailbox and I'm now recovering a recent copy from the backup. But I'd rather just blanket disallow all folder deletions. The user is using Thunderbird and this has happened more than once so I suspect Tbird is willing to let a folder get deleted too easily. Perhaps there was a delay in the confirmation dialog and the user clicked ahead and confirmed something he shouldn't have. I'm looking at <http://wiki.dovecot.org/ACL> and it looks like I should be able to use a group override to disallow "x" (mailbox delete) but the page says that groups aren't implemented, so I don't know how one says that nobody can do this for any mailbox. I'm using 1.2.rc15 from CentOS 5 (RHEL5 equivalent).

[Dovecot] Don't Understand Error Entry
by Carlos Williams 24 May '08

24 May '08

I am using dovecot-0.99.11-8.EL4 on my system and decided to check the logs since I just took over as the administrator on this system and I noticed the same error entry over and over in the logs. I went to /var/log/dovecot.err and see: imap(rangry): May 22 13:33:31 Error: Error parsing IMAP envelope: "Thu, 20 Apr 2006 10:10:01 -0400" "Re: Hi there I have a question" (("Rodney Angry" NIL "rodney.s.angry" "example.com")) (("Rodney Angry" NIL "rodney.s.angry" " example.com")) ((NIL NIL "rodney.s.angry" "example.com")) (("Gryder, Connie" NIL "CONSTANCE.L.GRYDER" "example.com")) NIL NIL "< DD3761B99DC88F4284EDE00D608383C65DF16C(a)0088-its-exmp01.us.example.com>" NIL I don't understand what this error message means and why its flooding my logs. I do know the that the name in parenthesis on line one is a user on my email server. <rangry> is a user on my domain with a valid email account but I can't tell if the problem is coming from example.com or originating from <rangry>. Anyone happen to know what is causing this? I don't know if you guys need my config here so I don't want to flood this message. If this makes sense to anyone, please let me know what I can do to resolve this or keep this from flooding my email server. Thanks!

[Dovecot] log contents questions?
by Knute Johnson 24 May '08

24 May '08

I switched from using Pegasus and POP3 to Thunderbird and IMAP for my email. Now I get a lot of "Corrupted index cache file" errors in my log.

[Dovecot] procmail --> deliver question
by Ben Budts 23 May '08

23 May '08

Hi there, I use dovecot-1.1-rc4, got imap, imaps, pop3 & pop3s working fine with the mbox format. I use sendmail-8.14.2 as an MTA, sendmail uses procmail as an LDA. I migrated to maildir format now, and pipe all my mail to deliver right now to be able to make use of the indexing etc... Problem is I run into some errors : #My .procmailrc PATH=/usr/bin:/usr/local/bin:/usr/sbin SHELL="/bin/bash" SENDMAIL="sendmail -oi -t" DELIVER="/opt/dovecot/libexec/dovecot/deliver" LOGFILE="$HOME/procmail.log" #/dev/null VERBOSE=on LOGABSTRACT = "all" #DEFAULT="$HOME/Maildir/" #MAILDIR="$HOME/Maildir/" :0 w | $DELIVER ##### My procmail.log : procmail: [12743] Wed May 21 13:43:38 2008 procmail: Assigning "LOGABSTRACT=all" procmail: Executing "/opt/dovecot/libexec/dovecot/deliver" Fatal: destination user parameter (-d user) not given procmail: Error while writing to "/opt/dovecot/libexec/dovecot/deliver" procmail: Program failure (64) of "/opt/dovecot/libexec/dovecot/deliver" procmail: Assigning "LASTFOLDER=/opt/dovecot/libexec/dovecot/deliver" procmail: Locking "/var/spool/mail/kris.lock" procmail: Assigning "LASTFOLDER=/var/spool/mail/kris" procmail: Opening "/var/spool/mail/kris" ####" It's not working out and he falls back to delivering his mail to /var/spool/mail/%u Could you guys point me out in the right direction please ? Another question about the logging with deliver... I've put the following in my deliver.conf : deliver.conf in the lda section : log_path = /var/log/dovecot/deliver.log info_log_path = /var/log/dovecot-deliver.log root@blaat:/home/kris# ls -la /var/log/dovecot/ total 232 drwxrwxrwx 2 root root 4096 2008-05-20 10:44 . drwxr-xr-x 11 root root 4096 2008-05-19 10:08 .. -rw-rw-rw- 1 root root 0 2008-05-20 10:44 deliver.log But it's not logging at all... Also tried the syslog alternative, no logging either. Also put set user or group ID on execution (s) on the deliver binary : -rwsr-sr-x 1 root root 693300 2008-05-19 09:38 /opt/dovecot/libexec/dovecot/deliver thx a lot Benjamin

[Dovecot] dovecot-sieve on freebsd
by Lazar Szilard 22 May '08

22 May '08

Hi,I need some help. I use dovecot and dovecot-sieve on a freebsd 7.0-release. everything worked fine without dovecot sieve. I want to deliver amavisd spam marked messages to the 'spam' folder of the user. the system uses virtual environment with multiple domains (and users).all want is a global sieve, to all users, all domains.I googled, but I cannot find the problem,my protocol lda section:protocol lda {    log_path = /usr/local/vmail/dovecot-deliver.log    sieve_global_dir = /usr/local/vmail/globalsieverc    mail_plugins = cmusieve    mail_debug = yes    log_path = /var/log/dovecot-deliver    info_log_path = /var/log/dovecot-deliver     postmaster_address = postmaster(a)tamann.hu    mail_plugin_dir = /usr/local/lib/dovecot/lda    sendmail_path = /usr/sbin/sendmail}globalsieverc:require "fileinto";if header :contains "X-Spam-Flag" "YES" {        fileinto "Spam";        stop;}thank you for your help,and sorry for my bad english.t

[Dovecot] auth_socket_path permissiones
by Adrián Ribao Martínez 22 May '08

22 May '08

Hello, I'm using dovecot 1.0 under debian etch. The lda socket path is set to: auth_socket_path = /var/spool/postfix/private/auth But this gives me the error: net_connect(/var/spool/postfix/private/auth) failed: Permission denied I suppose deliver is run as dovecot user. I read about running deliver as root with the suid bit set. I'm not quite sure if this is a good solution. Is there any other way. In the wiki says: "Most MTAs won't let you run deliver as root, so for now you'll need to make it setuid root. However deliver isn't designed to be run as setuid-root" My MTA is postfix, does someone know if postfix let me run deliver as root? If not, should I go to the setuid option? Thank you. -- Adrián Ribao Martínez

[Dovecot] Clients hang because imap-login discards post-login commands
by Mike Abbott 22 May '08

22 May '08

Some of my IMAP clients hang when connecting to Dovecot 1.1.rc5. I believe the problem is that imap-login reads eagerly rather than sparingly. If a client sends a login user password b select Inbox all at once, without waiting for the login reply before sending the select, imap-login eats the second command (reads it from the socket and does nothing with it; system call tracing confirms this) and the client hangs waiting for a reply to the select command. I can reproduce this simply using telnet to the dovecot on localhost, as long as I send both lines at once (I paste them in together). $ telnet localhost 143 * OK Dovecot ready. a login user password b select Inbox a OK Logged in. <dovecot never replies to select> This may also be true with pop3-login, I have not checked. It does happen (with IMAP) when authentication is delayed and Dovecot responds with "* OK Waiting for authentication process to respond.." but I believe that shares the same underlying cause as the simpler case above. I believe the login processes should read only as much as they need to satisfy the login request and leave subsequent commands in the socket for post-login processing. Or, the login processes should pass the remainder of their input buffers to the mail processes so no commands are dropped. This section of RFC 2060 explains why I think this: 5.5. Multiple Commands in Progress The client MAY send another command without waiting for the completion result response of a command, subject to ambiguity rules (see below) and flow control constraints on the underlying data stream. Similarly, a server MAY begin processing another command before processing the current command to completion, subject to ambiguity rules. [...] The exception is if an ambiguity would result because of a command that would affect the results of other commands. Clients MUST NOT send multiple commands without waiting if an ambiguity would result. If the server detects a possible ambiguity, it MUST execute commands to completion in the order given by the client. So it appears that both the client and Dovecot may be in violation, depending on how you define "ambiguity." The RFC does not explicitly define whether login causes an ambiguity, but I personally believe that login does "affect the results of other commands" (the login may fail, for instance). So the client should not issue commands before receiving the login reply, and Dovecot should not drop commands during login. I have reported the client issue to the developers of the IMAP client, as I am reporting the server issue to you. Fortunately for me, only one or the other needs to change to erase the symptom (hung clients), but fixing both would be best. Thanks for your attention.

[Dovecot] Dovecot or postfix Quota
by Adrián Ribao Martínez 22 May '08

22 May '08

Hello, I'm a bit confused with the dovecot quota support. What is it for? I thought postfix should be the one managing the quota. If I set up a quota in dovecot, does dovecot keep the messages size under certain limit? What happen when you reach the quota limit? What's the difference between postfix quotas and dovecot quota? I'm confused about this. Thank you! -- Adrián Ribao Martínez

[Dovecot] VMware and Time moved backwards
by Robert Henjes 22 May '08

22 May '08

Hi, I followed the discussions regarding the "time moved backward" problem and the use of ntp in such cases. At our department we are running two dovecot servers within an vmware server environment, and unfortunately the timedrift (with ntpd active) exceeds sometimes up to 30 minutes virtual drift within 10 minutes realtime (mostly into future). This is due to some overcorrections within the TSC algorithms of the vmware virtual machine. More information and some hints to workaround are documented here: http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=di… Nevertheless we are currently working on evaluating a stable solution by doing some system measurements, which would be the best option to cope with this problem, since the XEN environment seems to have a similar issue. Running "ntpdate -u" as a cronjob is not an option due to two facts: a) Time is moving quickly and may cause "major problems" ;) b) It is not recommended by the vmware team itself as well We are currently considering two options: a) Using the "clock=pit" kernel option, which may cause the system to be to slow b) using vmware tools and use only the ntp synchronisation of the host (we have currently only little experience with this). Also vmware tools are somewhat critical in case of updates. So our intention was to use as less vmware specific things as possible within the virtual machine, so only our host itself depends on vmware specific software. The question is, which option would you prefer? Is there another solution beside the mentioned ones? According to Timo's postings, workarounds within the dovecot itself to cope with "time moved backward" problems are not planned yet to be impelented. So best regards, Robert

Re: [Dovecot] VMware and Time moved backwards

Thank you for the prompt answers @Luuk Vosslamber >finding correct values for the following entrys in your vmware(host) >config file might solve some things: >host.cpukHz = 1596000 <== depends on processor speed ;-) >host.noTSC = TRUE >ptsc.noTSC = TRUE >hostinfo.noTSC = TRUE >tools.syntime = TRUE > >Above values go with the presumption that the host CPU is running at a >fixed frequency. The variable frequency seems to be the origin of this >problem.. We tried your parameters already, but they are not an option, unless you have the following a) machine smp disabled (enabled in our case) b) other machines on the host system have really low load c) vmware tools should not be missing on guest @Peter Hessler >never ever ever run ntp on virtual hardware. > >instead, run ntp on the host hardware, and tell the client to always obey the bios clock. I add "* * * * * /sbin/hwclock --localtime -->hctosys" >to my crontab for that. Thank you very much Peter, this hint opens up a bunch of new possibilities only mentioning "adjtimex" ... BUT: And this brings me back to, why I posted this issue to the dovecot mailinglist and not elsewhere: All these guest based solutions lead to a fixed time movement (we used previously ntpdate -u every 7 minutes, ntp itself synchronizes every 11 minutes with the hardware clock for calculating drifts), which happens about once per week, that the time movement backward is larger than 11 seconds between two dovecot imap operations, which leads to an immediate shutdown of the dovecot process. All other services on these machine can cope with this. So the question is how to get these adjustments smooth or close to realtime. Best regards, Robert Btw.: We are running Dovecot 1.0.13 from Debian etch-backports (which is an important information since debian seems to have its own rules ;) )

[Dovecot] Maildir locking by LDA of dovecot
by Mike Grozak 21 May '08

21 May '08

Hi all! First of all, I want ti thank the whole Dovecot community (developers for developing and fast responses, users for populating and responses too). Dovecot is a really good and fast IMAP server - it serves near 3000 in our installation. Now I have a problem and request community's help its resolving;) Dovecot version: 1.0.13, compiled with vpopmail support. I have an account spam(a)domain.com (:-), in which we put all our spam (we gather statistic later). There can be 10 and more delivery attempts in a second to maildir of this account during the spam attacks on our server. The queue of our server can grow up to 20k messages, and all of these messages are sent to spam(a)domain.com. I found a lot of such strings in dovecot.log file during the such DoS attack: dovecot.log:deliver(spam@domain.com): May 16 04:18:48 Info: msgid=<01c8b6da$a8bacf80$b7af2abe@sale>: save failed to INBOX: Timeout while waiting for lock dovecot.log:deliver(spam@domain.com): May 16 04:18:59 Info: msgid=<6611811842.20080516012444(a)poiusadfhnvxzmdiasdasgkhlsdkfg.com>: save failed to INBOX: Timeout while waiting for lock dovecot.log:deliver(spam@domain.com): May 16 04:20:06 Info: msgid=<01c8b6a8$7b552e00$a0a4034c@sale>: save failed to INBOX: Timeout while waiting for lock dovecot.log:deliver(spam@domain.com): May 16 04:20:14 Info: msgid=<360825920.32055246029506(a)mirgames.ru>: save failed to INBOX: Timeout while waiting for lock dovecot.log:deliver(spam@domain.com): May 16 04:20:50 Info: msgid=<01c8b6b1$0df9cb00$cc36dfc9@tek2>: save failed to INBOX: Timeout while waiting for lock dovecot.log:deliver(spam@domain.com): May 16 04:21:00 Info: msgid=<087901c7ca2d$ef272640$1e01a8c0(a)telefonia.InterCable.net>: save failed to INBOX: Timeout while waiting for lock dovecot.log:deliver(spam@domain.com): May 16 04:21:01 Info: msgid=<000701c8b6d2$01ff999f$c491aca7@snoueiij>: save failed to INBOX: Timeout while waiting for lock dovecot.log:deliver(spam@domain.com): May 16 04:22:32 Info: msgid=<000801c8b69b$060c0230$3cd8a4b7@cpbvlrx>: save failed to INBOX: Timeout while waiting for lock dovecot.log:deliver(spam@domain.com): May 16 04:22:45 Info: msgid=<000801c8b6a5$04ba6412$9910848d@aldldr>: save failed to INBOX: Timeout while waiting for lock dovecot.log:deliver(spam@domain.com): May 16 04:22:45 Info: msgid=<031401c772e2$adc5be40$1e01a8c0(a)mtu-net.ru>: save failed to INBOX: Timeout while waiting for lock dovecot.log:deliver(spam@domain.com): May 16 04:23:08 Info: msgid=<01c8b6db$0222fe80$b7af2abe@info>: save failed to INBOX: Timeout while waiting for lock My dovecot.conf: $ cat /etc/dovecot.conf | grep -v \# | grep -v ^\n protocols = imap pop3 log_path = /var/log/dovecot.log ssl_disable = yes login_user = dovecot login_process_per_connection = no login_max_connections = 1024 login_greeting = Server is ready. >>dotlock_use_excl = yes - can it be the reason? fsync_disable = yes first_valid_uid = 39 last_valid_uid = 39 first_valid_gid = 39 last_valid_gid = 39 max_mail_processes = 1024 maildir_copy_with_hardlinks = yes maildir_copy_preserve_filename = yes protocol imap { mail_plugins = quota imap_quota login_greeting_capability = yes imap_client_workarounds = outlook-idle } protocol pop3 { pop3_lock_session = no pop3_uidl_format = %08Xu%08Xv mail_plugins = quota } protocol lda { postmaster_address = postmaster(a)tversu.ru mail_plugins = quota cmusieve sendmail_path = /usr/lib/sendmail fsync_disable = no } auth_cache_size = 10240 auth_username_format = %Lu auth default { mechanisms = plain login cram-md5 socket listen { master { path = /var/run/dovecot/auth-master mode = 0666 } client { path = /var/spool/postfix/private/auth mode = 0666 user = postfix group = postfix } } passdb vpopmail { args = cache_key=%u dovecot } userdb vpopmail { } user = vpopmail ssl_require_client_cert = no } dict { } plugin { quota = maildir:ignore=Trash } What can I do for resolving this locks? May be, while looking into uidlist file, can dovecot LDA lock it? And other deliver processes can't open it and wait for him? --------------------------- WBR, Mike Grozak, TvSU IC

[Dovecot] Running sieve filters on already delivered mails
by Axel Gembe 20 May '08

20 May '08

I want to know what the best way to run sieve filters on already delivered mail is. Problem is that I have a rather large unfiltered mailbox and filtering it by hand would be a PITA. I don't mind coding something up to do this, but I just don't think that I'm the first one with this problem. Thanks - Axel
