[Dovecot] Multiple quota roots with quota-fs backend
by Ralf Becker 21 Jul '08

21 Jul '08

Today I've tried to configure multiple filesystem quotas, with some strange results. These are my two filesystems; both using quotas: * /dev/mail mounted to /var/spool/mail using AIX quotas for all users. Mailbox format is 'mbox' and they are named '/var/spool/mail/<logname>' * filer0:/vol/home mounted to /home/f0 via nfs using netapp quotas for all users. Mailboxes are all 'mbox' and located in '~<logname>/Mail' I've configured _two_ quota roots as described here: http://wiki.dovecot.org/Quota/FS?highlight=(two%20filesystems) plugin { quota = fs:Home:mount=/home/f0 quota2 = fs:Spool:mount=/var/spool/mail } This works like a charm, but when testing the configuration, the result was just surprising: * OK [CAPABILITY IMAP4rev1 SASL-IR SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN NAMESPACE LOGIN-REFERRALS UIDPLUS LIST-EXTENDED I18NLEVEL=1 QUOTA AUTH=PLAIN] Dovecot ready. . login rfttest XXX . OK Logged in. . getquotaroot "INBOX" * QUOTAROOT "INBOX" "Home" "Spool" * QUOTA "Home" (STORAGE 310360 1048576) * QUOTA "Spool" (STORAGE 89708 1000000) . OK Getquotaroot completed. . getquotaroot "Trash" * QUOTAROOT "Trash" "Home" "Spool" * QUOTA "Home" (STORAGE 310360 1048576) * QUOTA "Spool" (STORAGE 89708 1000000) . OK Getquotaroot completed. . logout * BYE Logging out . OK Logout completed. You see, that _always_ both quota roots are reported, whether the references mailbox is actually placed on this filesystem or not. However reading RFC2087 confirms me in the idea, that just the _related_ quota roots should be listed: -------------------------------8<----------------------------------------- 4.3. GETQUOTAROOT Command Arguments: mailbox name Data: untagged responses: QUOTAROOT, QUOTA Result: OK - getquota completed NO - getquota error: no such mailbox, permission denied BAD - command unknown or arguments invalid The GETQUOTAROOT command takes the name of a mailbox and returns the list of quota roots for the mailbox in an untagged QUOTAROOT response. For each listed quota root, it also returns the quota root's resource usage and limits in an untagged QUOTA response. Example: C: A003 GETQUOTAROOT INBOX S: * QUOTAROOT INBOX "" S: * QUOTA "" (STORAGE 10 512) S: A003 OK Getquota completed ------------------------------->8----------------------------------------- So in my opinion correctly reported quota roots should look like this: * OK [CAPABILITY IMAP4rev1 SASL-IR SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN NAMESPACE LOGIN-REFERRALS UIDPLUS LIST-EXTENDED I18NLEVEL=1 QUOTA AUTH=PLAIN] Dovecot ready. . login rfttest XXX . OK Logged in. . getquotaroot "INBOX" * QUOTAROOT "INBOX" "Spool" * QUOTA "Spool" (STORAGE 89708 1000000) . OK Getquotaroot completed. . getquotaroot "Trash" * QUOTAROOT "Trash" "Home" * QUOTA "Home" (STORAGE 310360 1048576) . OK Getquotaroot completed. . logout * BYE Logging out . OK Logout completed. Now I known what I want... but how to get it :-) While I see no way to use namespaces and/or quota rules to configure this behavior, patching quota.c, quota-fs.c and quota-private.h seems to be an option. A downside of this is, that I've to extend the quota plugin interface (quota_backend_vfuncs) defined in quota-private.h by adding an new callback function. Since all other quota backends don't have this new function, they have to initialize it with NULL. So there are side effects to other quota backends. This is the reason why I want to discuss the above described problem (and solution) before posting my patch :-) Regards, Ralf -- ______________________________________________________________________ Dipl.-Inform.

[Dovecot] v1.1.1: Some files not created with dovecot-shared permissions
by Eduardo M KALINOWSKI 21 Jul '08

21 Jul '08

Hi, I use dovecot-shared to add read permissions to the group in my mail server, which uses virtual users. This is only to ease backups. However, a few files are not created with the permissions in dovecot-shared. I've seen this happen to 'subscriptions', 'maildirfolder' (when dovecot-shared exists; the change to correctly create maildirfolder in this case is very recent), and possibly 'maildirsize' (I'm not sure about this one, it might be exim that is creating it with wrong permissions.) This has been tested in recent snapshot package, from the Debian repository listed at http://wiki.dovecot.org/PrebuiltBinaries. Here's dovecot -n for reference: # 1.1.1: /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 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: username_format=%n /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

[Dovecot] Upgrade to 1.1 maildir & shared folders problems

Hello, We recently upgraded to Dovecot 1.1 from 1.0.5 and we are having few issues: 1) Maildir's are not created anymore for new users if they dont excits, the directories where created before, is this a configuration issue? 2) Cannot subscribe to shared folders, if currently subscribed they work fine but cannot re-subscribe, also i noticed that the control directory for the namespace is not created anymore, before it was, any ideas? //sami conf: 1.1.1: /usr/local/etc/dovecot.conf base_dir: /var/run/dovecot/ protocols: imap pop3 ssl_disable: yes disable_plaintext_auth: no login_dir: /var/run/dovecot//login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login login_greeting: ready. login_processes_count: 5 verbose_proctitle: yes first_valid_uid: 1000 mail_location: maildir:~/:INDEX=/var/dovecot/index/%u:CONTROL=/var/dovecot/control/%u mail_nfs_storage: yes mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_process_size: 1024 mail_plugins(default): acl quota imap_quota mail_plugins(imap): acl quota imap_quota mail_plugins(pop3): mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 imap_client_workarounds(default): outlook-idle, delay-newmail imap_client_workarounds(imap): outlook-idle, delay-newmail imap_client_workarounds(pop3): namespace: type: private separator: / location: maildir:~/:INDEX=/var/dovecot/index/%u:CONTROL=/var/dovecot/control/%u inbox: yes list: yes subscriptions: yes namespace: type: public separator: / prefix: shared/ location: maildir:/var/mail/jaetut:INDEX=/var/dovecot/jaetut/index/%u:CONTROL=/var/dovecot/jaetut/control/%u list: yes subscriptions: yes auth default: passdb: driver: sql args: /usr/local/etc/dovecot-sql.conf userdb: driver: sql args: /usr/local/etc/dovecot-sql.conf userdb: driver: prefetch plugin: quota: fs acl: vfile:/usr/local/etc/dovecot-acls

[Dovecot] AIX: mntctl implementation for NFS quota support
by Ralf Becker 21 Jul '08

21 Jul '08

Hi Timo, Hello list, I've played around with dovecot-1.1.1 on AIX to get quotas (especially NFS quotas) to work. I've found that dovecot doesn't implement handling of 'mntctl' and so it is unable to determine filesystem mountpoints on AIX correctly. Your'll find more information about 'mntctl' here: http://publib.boulder.ibm.com/infocenter/systems/index.jsp?topic=/com.ibm.a… Okay... I've added mntctl support to 'lib/mountpoint.c' today. My tests are looking good and so I'd like to share the patch. While I'm still not really familiar with dovecots memory management, I need someone who is familiar with it to have a look on my lines of code. Especially the usage or p_new, t_strconcat and p_free should be checked. :-) To activate the patch you have to add "#define HAVE_VMOUNT_H 1" do 'config.h'. Maybe someone wants to alter configure* to do this automatically? And of course Timo, if you find it useful, you may include the code in one of the next dovecot releases.

[Dovecot] exim, LDA, quota
by Marcin Gryszkalis 20 Jul '08

20 Jul '08

Hi I configured Exim with dovecot LDA and added quota (dict/mysql). It works but it seems that dovecot is not reporting situation back to exim process - it looks like Exim returns OK(accepted) to smtp sender before the message is actually delivered - if the quota is exceeded then LDA drops the mail and sends DSN. Is it possible to change that behavior to report problem immediately (within SMTP session)? regards -- Marcin Gryszkalis, PGP 0x9F183FA3 jabber jid:mg@fork.pl, gg:2532994 http://the.fork.pl

[Dovecot] group ownership of new shared folders

Between versions 1.0.4 and 1.0.5 there were some changes to the way dovecot-shared group ownership is propogated into new maildirs. Changing the group of new_dir/{tmp,new,cur} was added, but changing the group of new_dir itself was removed. As far as I can tell, this latter change may have been accidental.

[Dovecot] No log for hitting login_max_processes_count?
by Adam McDougall 20 Jul '08

20 Jul '08

I think today just due to increased use, my mail servers hit login_max_processes_count. It wasn't obvious what was happening, logins just weren't acting like they should and sometimes would get disconnected before given a prompt from the server. Something made me think to check if I had too many of certain dovecot processes and I found I had 128 imap-login processes on both servers, but nothing in the logs seemed to point that out for me. Should there be? It would have been alot easier to debug. Also, this seems to be from general use, doesn't seem like a DoS, so is this just a setting I should keep an eye on and increase it by reasonable amounts as needed? Thanks.

[Dovecot] 1.1.1, mbox_snarf and duplicate messages
by Laurent.Moineau＠math-info.univ-paris5.fr 20 Jul '08

20 Jul '08

Hello, I recently switched to dovecot 1.1.1 with mbox_snarf from uw-imap with mbox driver enabled. The mail is delivered by procmail in /var/spool/mail/user Most of my users have a file INBOX located in $HOME/mail The mail is transfered from /var/spool/mail/user to $HOME/mail/INBOX every time an imap connection is done. Things are OK with clients like thunderbird or evolution, but with imp or mostly squirrelmail messages are duplicated (some user reported that a single message duplicated 50 times !). Every imap connection (thunderbird or webmail) terminates with a warning : Timeout leak: 0x4534e0 I 've tried to use fcntl in : lock_method, mbox_read_locks and mbox_write_locks but things are worse than traditional dotlocks. My config on my first server : sendmail-8.14.1 procmail dovecot 1.1.1 On the second server : The webmail (imp and squirrelmail, latest versions) is installed on another server but uses server 1 as imap server. I 've tried to use an imap proxy (perdition) but without any improvement as far as this problem is concerned. I previously used another dovecot server on that machine with an NFS mount to get /var/spool/mail from the first server with the duplicate problem too. I enabled mail_log and there where a bunch of Info messages like this : dovecot: Jul 11 18:20:11 Info: IMAP(foo): copy: uid=22, dest=/users/foo/mail/INBOX, msgid=<4877879C.40104(a)math-info.univ-paris5.fr>, size=2223 Any hint ?

It appears to occur when there are a lot of requests being sent to the LDAP servers from both Dovecot and Sendmail (I am guessing about this, since I have also seen "Server busy" messages regarding LDAP auth). dovecot: auth(default): file db-ldap.c: line 310 (ldap_conn_retry_requests): assertion failed: (conn->connected) dovecot: auth(default): Raw backtrace: dovecot-auth [0x806daf1] -> dovecot-auth [0x806da0c] -> dovecot-auth [0x8059607] -> dovecot-auth [0x8059b1d] -> dovecot-auth [0x8059b7b] -> dovecot-auth(io_loop_handler_run+0x110) [0x8070c90] -> dovecot-auth(io_loop_run+0x1c) [0x80701cc] -> dovecot-auth(main+0x2fe) [0x805b01e] -> /lib/libc.so.6(__libc_start_main+0xdc) [0x3efdec] -> dovecot-auth [0x8051161] dovecot: child 23178 (auth) killed with signal 6 Dovecot seems to recover from this error and continues to handle auth requests properly. Thanks, Eric

[Dovecot] Multiple auth client sockets
by Ulrich Zehl 20 Jul '08

20 Jul '08

I use two seperate Postfix instances as MSAs (so that different policies are simpler to configure), and both of them require Dovecot SASL support. Since Postfix' smtpd is chrooted (at least in the Debian package), the client socket needs to be somewhere under the instance's queue_directory. This means I need two different auth client socket paths. When I simply specify two "client { ... }" in dovecot.conf, the second takes precedence over the first. Besides using a second dovecot instance, which I'd like to avoid, what ways are there to run a second client socket? Ulrich

[Dovecot] [Help] quota_rule with LDAP backend, dovecot-1.1.1
by Zhang Huangbin 20 Jul '08

20 Jul '08

Hi, all. I use dovecot-1.1.1 with OpenLDAP as userdb. but i failed to convert quota value as expect. I set '10' as mail quota, and it should be '10M' as expect, but it's not effect, dovecot always uses 'quota_rule' setting in dovecot.conf. How can i fix this issue? 10*1047576? I have 'mailQuota' attr in ldap schema, such as: ----8<---- mailQuota: 10 # <- 10M ----8<---- My dovecot-ldap.conf: ----8<---- user_attrs = homeDirectory=home,mailMessageStore=maildir:mail,mailQuota=quota_rule=*:bytes=%$ ----8<---- And my dovecot.conf: ----8<---- plugin { quota = maildir # Quota rules. quota_rule = *:storage=10M } ----8<---- -- Best Regards.

[Dovecot] configuration query
by Michael Mounteney 20 Jul '08

20 Jul '08

Hello, please excuse my asking a question about simple configuration rather than something about a suspected bug or other detailed enquiry. I've set up dovecot (1.0.13, from http://www.blastwave.org) and when Thunderbird connects to it, all is well and I see folders as expected. When MacOS X mail connects however, it sees my home directory on the dovecot machine, not the mail directory. Now setting-aside the obvious rant about why MacOS has to be gratuitously different *again*, I would like to configure dovecot not to serve my home directory. I keeping saying I/my as this is just a personal set-up at home. This IMAP stuff is a bit involved but I thought namespaces would be the answer but it seems not. That is, I have namespace private { location = /var/marchive/%u inbox = yes } but even this still allows Mac Mail to see the home directory. What else should I do to stop dovecot serving my home directory ? I realise that there is also a problem with the client, that Mac Mail is *asking for* my home directory rather than the mail folder, but that's another problem, not for this list. Thanks in expectation.

[Dovecot] BUG: messages created with permissions not respecting umask
by Thomas Vander Stichele 20 Jul '08

20 Jul '08

Using dovecot 1.0rc15, together with postfix and dovecot-lda. umask is set to 0007. This should ensure directories and files get created with read/write permissions for both user and group. However, dovecot-lda writes files with 600 permissions, instead of 660. So dovecot does not seem to respect the umask configuration property for local mail delivery. In my particular case, I have vmail:vmail own the mail directories, and a backup user part of the vmail group. However the backup user cannot read the mails and thus back them up properly. Suggestions: - respect the umask for file delivery as well - alternatively, take the parent directory's permissions, strip executable bits, and apply to file Thanks Thomas

[Dovecot] Run script before delivery
by Juan Asensio Sánchez 20 Jul '08

20 Jul '08

Hi Is it possible to run one script before the "real" delivery of a message (with lda, or before the execution of the sieve scripts) but after the creation of necessary folders (Dovecot automatically creates the folders for virtual users)? I want to to this to manually create a fixed empty sieve script in each user home folder, so in the global sieve script include that personal script, because if personal script doesn't exists, global script is not executed, or am I wrong? Thanks in advance.

[Dovecot] Need suggestion regarding index file and Quota settings.
by Tim Chen 20 Jul '08

20 Jul '08

Dear All, My system has about 30,000 accounts and these accounts are created as unix system users. Each account has its own entry in /etc/passwd with different UID and home directory. We plan to deploy an Layer 4 switch as a load balancer. Proposed architecure is as the following: ---- internet ---- Layer 4 switch ---- mail server1 ---- NFS storage | | |--- mail server2 -----| Both mail servers will share the same storage which contains users' home with Maildir inside. Dovecot will be installed on the mail servers serving pop3 and imap4 protocols. Since the layer 4 switch will direct connection to backend mail server in random(or some of its algorithm), users can not guarantee which mail server to use. My first question is which kind of INDEX settings should I apply? 1) INDEX=MEMORY 2) INDEX=/nfs/%u 3) INDEX=/var/spool/%u Will INDEX stored on disk outperform INDEX stored in memory? If INDEX stored on NFS storage, we can be sure the consistency of INDEX file, but what about the performance and locking problem? If INDEX stored on local disk, since users may connect to different mail servers every time. Will that impose the problem of inconsistency? What kind of syndrome will happen if the INDEX became inconsistent to real maildir content? My second question is about quota. We use maildir as mail storage format. Our users were divided into 3-4 groups, each group of users with different quota size ranging from 100MB - 1G. To my best knowledge, dovecot's quota setting in config file supports only "one global configuration". (We are not using db, we use only /etc/passwd). dovecot.conf quota_rule = *:storage=10MB Since dovecot supports both fs and maildir++ quota, I would like to ask for your suggestion: 1. Should I use system quota instead? How about the comparision of performance? Is there any drawback/limitation using system quota? 2. Is there any settings of dovecot that could fullfil my situation? 3. My thought is to modify dovecot.conf, comment out quota_rule = *:storage=10MB and leave only the quota = maildir in the plugin { block. According to my experiment, dovecot will read the maildirsize file under user's home. Then I have to set the maildirsize file for every user individually! It seems to be a little crappy but works. Looking for your valuable suggestions! Thanks very much. Tim Chen

[Dovecot] OT: Deleting email
by Mauricio Tavares 19 Jul '08

19 Jul '08

I have a mail server running postfix and then using dovecot so others can reach it using imap. I go check mail using thunderbird and delete a few emails, emptying the trash afterwards. Then I quit it and access it using pine. The deleted emails are still there, marked as marked for deletion. I delete a few other emails within pine and quit. It asks to delete the marked emails, I tell go for it, and it does. When I go back to THunderbird all those emails are gone. Next I tell thunderbird to mark certain messages as spam and delete email I marked as spam. I quit it and go back to pine. The spam marked messages which thunderbird swore were deleted are still there. THis really does not seem to be a dovecot issue, but has someone seen that happen? If so, what is going on?

Re: [Dovecot] changing INTERNALDATE or similar
by Karl Rudnick 18 Jul '08

18 Jul '08

Looking at the IMAP4rev1 protocol (RFC 2060), we have the following definition: INTERNALDATE The internal date of the message. 2.3.3. Internal Date Message Attribute The internal date and time of the message on the server. This is not the date and time in the [RFC-822] header, but rather a date and time which reflects when the message was received. In the case of messages delivered via [SMTP], this SHOULD be the date and time of final delivery of the message as defined by [SMTP]. In the case of messages delivered by the IMAP4rev1 COPY command, this SHOULD be the internal date and time of the source message. In the case of messages delivered by the IMAP4rev1 APPEND command, this SHOULD be the date and time as specified in the APPEND command description. All other cases are implementation defined. How could any implementation of this protocol possibly use a file system time stamp to represent that important piece of meta-data, no matter where the file lives? It seems totally reasonable that this is what Outlook uses for the Received date (and I rarely defend Microsoft). This seems like a real design flaw in the dovecot implementation. I am fairly new to dovecot (and like many aspects of it over uw-imap), but having to really be careful with my mail store's mtimes borders on the absurd. I realize it is "implementation defined", but the intent of the definition surely does not refer to file system time stamps. Any chance this can be reconsidered? Is this an actual dovecot issue or a more general Maildir issue?

[Dovecot] v1.1.0 released
by Timo Sirainen 18 Jul '08

18 Jul '08

http://dovecot.org/releases/1.1/dovecot-1.1.0.tar.gz http://dovecot.org/releases/1.1/dovecot-1.1.0.tar.gz.sig Two hours later than promised, I slept longer than intended. :) No changes since v1.1.rc13. Below are the largest changes since v1.0: * After Dovecot v1.1 has modified index or dovecot-uidlist files, they can't be opened anymore with Dovecot versions earlier than v1.0.2. * See doc/wiki/Upgrading.1.1.txt (or for latest changes, http://wiki.dovecot.org/Upgrading/1.1) for list of changes since v1.0 that you should be aware of when upgrading. + IMAP: Added support for UIDPLUS and LIST-EXTENDED extensions. + IMAP SORT: Sort keys are indexed, which makes SORT commands faster. + When saving messages, update cache file immediately with the data that we expect client to fetch later. + NFS caches are are flushed whenever needed. See mail_nfs_storage and mail_nfs_index settings. + Out of order command execution (SEARCH, FETCH, LIST), nonstandard command cancellation (X-CANCEL <tag>) + IMAP: STATUS-IN-LIST draft implementation + Expire plugin can be used to keep track of oldest messages in specific mailboxes.

[Dovecot] Kerberos check logic incorrect
by Bryan Jacobs 18 Jul '08

18 Jul '08

In configure.in, there is a check that does `krb5-config --version | grep -v 1\.2`, making sure there is no "1.2" in the version of Kerberos in use. This is to prevent compiling against MIT Kerberos version 1.2, which is too old for Dovecot. Unfortunately for this idea, Heimdal 1.2.1 is out. And Dovecot builds fine against it. Whoever committed this check also appears to have removed the comment warning that it was broken, to add insult to injury. Please fix your checks to be for FEATURES, not version numbers. You never know when something else that correctly implements the features you want will come along. Bryan Jacobs

Re: [Dovecot] changing INTERNALDATE or similar
by Rudnick, Karl 18 Jul '08

18 Jul '08

I successfully executed the script which "fixed" my mail store. I also see now why there isn't a buttoned down solution out there. The basic steps are simple as outlined below, but when dealing with ~35,000 emails going back before 1993, there were just about a dozen that didn't adhere to the "Date:" screening and subsequent capture for use by "touch --date". Adding these exceptions to my script completely automated the INTERNALDATE resetting, but I would not publish this publicly on the internet. Nevertheless, I would share it with anyone who requests through this mail group given the caveat that it is only guaranteed to work for MY personal data store. Thanks - Karl -----Original Message----- From: Rudnick, Karl Sent: Thursday, July 17, 2008 9:06 AM To: dovecot(a)dovecot.org Cc: Timo Sirainen Subject: RE: [Dovecot] changing INTERNALDATE or similar Terrific - I'll just write a script to: 1. create a list of all Maildir folders ending in "/cur" 2. remove dovecot.index* in each folder 3. For each mail file in each Mailder /cur folder: a. grep/sed "Date:" to grab first date/time stamp in email b. pipe the output of a. into "touch --date" for that file On my windows side, all the imap info is saved in one pst file in "C:\Documents and Settings\<user>\Local Settings\Application Data\Microsoft\Outlook\Outlook*imap*.pst" and if I blow it away it gets correctly rebuilt - I just tested it and the blown away index files get rebuilt so that Outlook then has the correct Received date displayed. Pretty easy to do, but surprised a script wasn't openly available - or at least my googling skills weren't good enough. Since I have ~35,000 emails in about 450 folders, this needs to be scripted. I'll make it available when I get it smoothed out.

So you can use whatever utility/script you want to modify the mtime (I don't have any suggestions). Then delete dovecot.index.cache file to make sure the old value wasn't cached. You might also have to recreate the account in your clients to make sure they haven't cached the old values.

[Dovecot] changing INTERNALDATE or similar
by Karl Rudnick 17 Jul '08

17 Jul '08

I have a question which others must have encountered. I switched from uw-imap to dovecot-imap a few months ago and moved my fairly large mail archive (~15 yrs) by simply mounting both accounts in a mail app and simply copying my folders over. This worked well, and all my mail is in order when I view it in evolution or thunderbird on any number of machines. However, since our company uses MS Exchange Server, when I add my dovecot imap account to outlook, everything is great except the received dates - it looks like the date I made the transition, but in all instances it's not simply the time stamp in the Maildir folder. I googled around on this and have gathered that this date is coming somewhere from within the dovecot index file. Is there a utility for scanning that so I can ascertain where the date shown in Outlook is coming from? Is there also a utility which would just reset the INTERNALDATE (or whatever it is that Outlook is keying on) to the date in the message on the "Date: ..." line? This issue is not life threatening as I don't use Outlook much, but when I do, it is confusing to not have the "Received" column be meaningful, especially for sorting. Thanks for any help - Karl

[Dovecot] Change text from default overquota message - Possible?
by k bah 17 Jul '08

17 Jul '08

I'm using Dovecot 1.0.5-6 (SuSE 10.3) and using dovecot deliver. Is it possible to change the subject/body of the default overquota message (it says "Automatically rejected mail" on the subject) and also the text from the message? I don't wan't to "hack" anything, just if it's possible to do by editing config files. thanks = Web-Based Privileges Certification Quickly setup a collaborative Web-based facility for business managers to certify authorizations and IT privileges.

[Dovecot] thanks
by Andrew Schulman 17 Jul '08

17 Jul '08

Here's just a note of thanks to the developers of Dovecot. I first starting using just the Dovecot IMAP server about a year ago, and it's been working fine for that. More recently I've started to use the managesieve and LDA components as well, and what I find now is that this system works well and is straightforward to configure, well-integrated, and relatively well documented. Also, the LDA has a significantly stronger set of sieve capabilities than exim's. All in all, Dovecot is doing a lot of work for me now and doing it well. Hats off to the developers. Andrew.

[Dovecot] question dbox folders subscription
by Robert Schetterer 17 Jul '08

17 Jul '08

Hi, creating a imap dbox folder and deletion now works with thunderbird, but the subscription file seems not be updated ,somekind. After the deletion of a folder it apears again after restart thunderbird .Then ,by click on it , you get message , folder not exists ( which is true ) but for disapaer the folder must be be manually unsubscribed. this isnt the same behavior like i.e with maildir with maildir the deleted folder shows up too, after restart, but with clicking on it, it disapaers without any message to tb anyone an idea to this? -- Best Regards MfG Robert Schetterer Germany/Munich/Bavaria

[Dovecot] antispam plugin, amavis and sa-learn
by Johannes Bauer 16 Jul '08

16 Jul '08

Hello, I would like to use the Dovecot antispam plugin to train SpamAssassin via sa-learn. I compiled the plugin and got it to work with the sendmail backend, which I tested by having it send a message to me. As I'm calling SpamAssassin with amavisd-new, I have a system-wide Bayes db, maintained by the amavis user. As expected, the antispam plugin calls the configured binary as the mail user (I'm running deliver as suid, with mixed virtual and system accounts). My question is: How can I get the plugin to call sa-learn as user amavis? I have tried the following things: (1) making the amavis user's .spamassassin directory to world-writeable and handing the path to sa-learn with the --dbpath parameter. That failed - the IMAP client says "Move not allowed" when I try to move a message to or from the Spam IMAP folder. (2) making a suid copy of sa-learn with owner amavis. This failed because of an sperl error. (3) editing sudoers to allow 'sudo -u amavis sa-learn' without a password. This works fine on the command line, but fails with the same error as (1) when used with the plugin. Although I compiled the plugin from git with debugging to syslog activated, I do not get any error messages in mail.log where all messages from dovecot are logged. Now, I know that the methods above aren't exactly secure, so if anybody has a different way of training SpamAssassin with the antispam plugin in a amavis setup, I would appreciate it. Thank you, Johannes

[Dovecot] Maildir folder renaming disagreement among IMAP clients
by Adam McDougall 16 Jul '08

16 Jul '08

A user alerted me to a problem when he renamed an upper level mail folder and lost access to a lower level folder under it. I tried with and without listescape, it didn't seem to make a difference, and I saw no errors in the dovecot log. Symptoms are if a client has a maildir folder tree .a and .a.b and renames a to c in their client, Thunderbird shows c/b but b is inaccessible since it is still actually .a.b on the filesystem, unsubscribed but accessible if you go subscribe to it. Outlook Express seems to behave the same except it cannot access "b" (.a.b) at all now because "a" no longer exists. Subscribe window shows it, but you cannot subscribe (as expected for OE). According to the rawlog, Thunderbird just tries to rename the top level folder and change subscriptions, but doesn't rename other maildirs to match the new top level folder. On the other hand, Outlook seems to rename and subscribe the top folder and subfolders properly. Who is right, should the mail client be doing all the work, or should dovecot be doing more, or do I have something setup wrong? I'm pasting what I think are essentials from the rawlogs, and my dovecot -n.

[Dovecot] Postfix+maildrop+deliver?
by Tom Fernandes 16 Jul '08

16 Jul '08

Hello, I currently use procmail without the deliver LDA but would like to switch to using deliver. I also would like to get away from procmail for various reasons. Otherwise I could use the procmail-patch from http://dovecot.org/pipermail/dovecot/2006-July/014656.html AFAICS. I don't want to use sieve because it's too limited and can't see a similar patch like the one for procmail available for maildrop. What setup would I use for Postfix+maildrop+deliver? thanks, Tom

[Dovecot] ACL in sub-folders

Hi all, I've set up some shared folders and I'm controlling the access to them with the ACL plugin. As far as I know, ACL rules are not applied to sub-folders, right? So, when a user adds a new sub-folder, I need to add a dovecot-acl file granting read permissions to others users, right? Does exists any way to implement it using some dovecot feature? Or must I find my way? Just to be sure :) Thank you in advance. -- Imobach González Sosa Banot.net http://www.banot.net/

Not true! simple way: Just change the default config TB create your account from with the settings you need. You can find the file under your program dir i.e. C:\Programme\Mozilla Thunderbird\defaults\pref Compare the defaults to your working set of setting and change them accordingly. You can activate TLS or CRAM-MD5 and so an.
