[Dovecot] ACLs, imap and launchd
by Axel Luttgens 30 Jun '09

30 Jun '09

I was going to experiment with ACLs when I faced a small problem. It is just sufficient to enable the acl plugin for getting the behavior described hereafter. When launching dovecot from the command line, one gets: sh-3.2# /usr/local/dovecot/sbin/dovecot -F ILoading modules from directory: /usr/local/dovecot-1.2.rc6/lib/ dovecot/imap IModule loaded: /usr/local/dovecot-1.2.rc6/lib/dovecot/imap/ lib01_acl_plugin.so IEffective uid=65534, gid=65534, home=/tmp Iacl: No acl setting - ACLs are disabled ^C In fact, a "dummy" imap process is run so as to fetch the capability (see master-settings.c); that process is run with an hardcoded uid/gid 65534. But this appears to be problematic when dovecot is started from launchd; clearly, launchd doesn't like arbitrary users, as it may be seen from system.log: org.dovecot[28382]: ^AILoading modules from directory: /usr/local/ dovecot-1.2.rc6/lib/dovecot/imap org.dovecot[28382]: ^AIModule loaded: /usr/local/dovecot-1.2.rc6/lib/ dovecot/imap/lib01_acl_plugin.so com.apple.launchd[1] (com.apple.launchd.peruser.65534[28384]): getpwuid("65534") failed com.apple.launchd[1] (com.apple.launchd.peruser.65534[28384]): PID 28383 "imap" has no account to back it!

A workaround is to create the corresponding system user and group; launchd then doesn't complain anymore and everything seems to be working fine. But I feel somewhat uncomfortable with that... Wouldn't it be possible, for example, to consider using a system user such as "nobody" (unless I'm wrong, it should be defined on any unix flavor)?

[Dovecot] No folders listed in felamimail
by Jonathan Knight 30 Jun '09

30 Jun '09

Egroupware 1.4.004 I thought I try and solve a long standing bug we've had with felamimail not listing folders from our dovecot server. Watching dovecot's packet dumps I'm seeing dovecot do a namespace call and the a list call. Felamimail does a namespace and gets back * NAMESPACE (("" "/")) NIL NIL which is how I've configured dovecot to keep the client configuration very simple. Now Felamimail does a LIST "" "" which gets no folders returned and is obviously why it won't show anything in the felamimail display. I was expecting felamimail to do something more like: LIST "" "%" or LIST "" "*" Is there something I need to configure to make felamimail happy with our dovecot configuration? We use dovecot with outlook express, thunderbird (1,2,3), Mozilla, squirrelmail, iPod, iPhone and symbian with no issues so I'm tending towards felamimail being the source of the problem. Jon.

[Dovecot] Location of sieve_global_dir setting
by Rainer Frey 30 Jun '09

Hi, I'm a bit confused by the Wiki. Do the settings "sieve_dir" and "sieve_global_dir" belong to the lda or the plugin section (Dovecot 1.1.11)? Thanks Rainer

[Dovecot] SSL / TLS
by Carlos Williams 30 Jun '09

30 Jun '09

I am running Postfix and Dovecot on my mail server. I am required now to have SSL/TLS on my mail server. I did check and found out that I have a SSL certificate with Verisign issued to my mail servers FQDN. Now my question is when reading the Dovecot Wiki, I noticed it said that it is not common to use SSL but rather TLS on most mail servers. Even though SSL will work, which should I use on my server? We already have a purchased SSL certificate but does that really matter? Should I simply just revoke that certificate & use TLS instead? So when I read this link: http://wiki.dovecot.org/SSL/DovecotConfiguration Is it talking about a actual SSL certificate or TLS? Thanks for any clarification! - Carlos

[Dovecot] Users with large (4GB) inboxes crippling dovecot
by robforrest 30 Jun '09

30 Jun '09

Hi all, I'm new here and would very much appreciate any help you can give me. We are running a rather outdated mail server that until recently has been running beautifully. Under the pretense of "it is ain't broke, don't fix it" it hasn't been updated so is running Fedora Core 4 and dovecot v0.99.14. What is happening is that as users log in (via thunderbird), they are shown the contents of their mailboxes. However, when they try and access a given email, they get no response even if they wait upwards of 10 minutes. I believe that the problem has arisen from their huge inboxes, several users have inboxes in excess of 4GB. Do any of you know how I could split these large mbox files down in to manageable chunks of 1GB? Please be aware that I only have remote access to the server over a modest internet connection. Thanks again for any suggestions.

[Dovecot] Recommended Groupware?
by it-dovecot＠ml.epigenomics.com 29 Jun '09

29 Jun '09

Hi, is there a recommended groupware (email + calendar + address book + syncing with mobile devices) on top of an existing dovecot installation? Most existing commercially supported groupwares come with their own mail storage engine. I would like to keep dovecot as the email storage engine because of the maildir format which greatly helps with backup & restore. Regards -- Robert Sander

[Dovecot] Dovecot Expire doesn't work
by Stef Simoens 29 Jun '09

29 Jun '09

Hello, I'm using dovecot and I want to use the "expire" plugin. However, it doesn't work, i.e. mails do not get deleted. I ran `/usr/sbin/dovecot --exec-mail ext /usr/libexec/dovecot/expire-tool --test` and besides printing Info: stef/Trash: no messages left Info: stef/Spam: no messages left it doesn't do anything (especially not deleting e-mails). Obviously, in stef/Trash and stef/Spam, there are e-mails waiting to be deleted. I'm using dbox as mail storage; and use dbox:/var/mail/%u as mail_location in dovecot.conf. Furthermore, I'm running 1.1.16 on a gentoo PPC system. This is the output from `dovecot -n` # 1.1.16: /etc/dovecot/dovecot.conf # OS: Linux 2.6.29-gentoo-r2 ppc Gentoo Base System release 1.12.11.1 xfs listen: *, [::] ssl_cert_file: /etc/ssl/dovecot/server.pem ssl_key_file: /etc/ssl/dovecot/server.key login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login verbose_proctitle: yes mail_privileged_group: mail mail_location: dbox:/var/mail/%u mail_plugins: expire auth default: verbose: yes debug: yes passdb: driver: pam args: * userdb: driver: passwd socket: type: listen master: path: /var/run/dovecot/auth-master mode: 384 plugin: quota: fs:Disk Quota expire: Trash 7 Spam 30 expire_dict: proxy::expire dict: expire: db:/var/lib/dovecot/expire.db A strace on `/usr/sbin/dovecot --exec-mail ext /usr/libexec/dovecot/expire-tool --test` shows the following output: mkdir("/var/mail/root", 0770) = -1 EEXIST (File exists) stat64("/var/mail/root/Trash/dbox-Mails", 0xbfda2708) = -1 ENOENT (No such file or directory) write(2, "Info: stef/Trash: no messages lef"..., 35Info: stef/Trash: no messages left ) = 35 which explains why nothing happens (stat64("/var/mail/root/Trash/dbox-Mails", which is empty, it should not even exist, but it passes by a mkdir), but why does it want to check /var/mail/root and not /var/mail/%u (i.e. why no stat64(/var/mail/stef/Trash/dbox-Mails))? Thanks for your help and kind regards, -- Stef Simoens

We are running a Red Hat Enterprise Linux environment with Dovecot IIMAP, Exim and mySQL 5.0.81, Apache 2.2.11 We are looking for several server side scripts: 1. Create a user account automatically at the completion of our registration process. i.e. username(a)ourdomain.com and existing MD5 password that is associated with his/her user account 2. Add a new user to an existing subscriber email whitelist (add buddy function) 3. Add an existing user to an existing subscriber email blacklist (block buddy function) Our preference is to receive access to a publicly available scripts. Alternatively, to come to a commercial arrangement with a party who has written or who is prepared to write the same.

[Dovecot] sievec error: "fileinto require missing"

So with only 3 POP3 users, why should so many login processes be spawned? I can understand 10-15. But 100 definitely indicates either the processes are not dying or something else happening on the system which is causing such high number of login processes. The system definitely needs to be checked for some kind of attack, a rogue process running on the system or something else. > >> My idle box has 64 imap-login processes and no, I'm not under a >> dictionary attack :) I am not sure what your load is (user base, system config etc), but I will give you my typical load here. I run mail server for about 6000 users with a mix of 70% POP3 and 30% IMAP (thro webmail). And here are the typical stats (I run a script in the background collecting this data every 5 secs): pop3-logins:12 pop3-connections:8 IMAP-logins:7 IMAP-connections:11 I have read other opinions in this thread by Timo & others. And I am interested in a few things. So if you will indulge me, maybe it will be useful for others who face these kind of issues Timo Wrote: You can also just decrease login_process_max_count Wouldn't decreasing the login_process_max_count simply create more problems. Now users will start experiencing timeouts sooner than before, because whatever is causing the login processes to increase (attack, rogue process or whatever) will *always* be trying to login and genuine users will be denied login. So without knowing the root cause of the issue simply decreasing or increasing the login_process_max_count will lead to other problems. Correct me if I am wrong. Rodman Wrote: I'll go ahead and lower that limit to something that fits my usage better. No, I think leave that value to default and try and identify the root cause and prevent it. Noel Wrote: What would be nice is, an anti brute force option Yes, that would be nice. But consider a situation where the system is not under brute force attack, but for some reason the number of login processes keep on increasing by the hour. This would ultimately lead the system to deny connections to the users. Is there a way to track what is happening? strace would be too complicated for us field guys to work with. Any suggestions?

[Dovecot] Dovecot v1.2 ACL inheritance for new subfolders (aka copying ACLs)
by Steffen Kaiser 28 Jun '09

28 Jun '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, http://wiki.dovecot.org/ACL mentions: "Currently there is no ACL inheritance." However this applies to a folder inherit ACLs to existing subfolders; when you share a folder and a non-owner creates a sub-folder within, no ACLs are set, hence, the creator cannot access the new folder. Could the "create mailbox"-process copy the ACLs to the sub-folder? Actually, I would like most, if this is done regardless if owner or non-owner creates subfolders.

[Dovecot] bzip2 compression bug
by fernando＠dfcom.com.br 28 Jun '09

28 Jun '09

Hi, I compressed many files using bzip2, but in some cases it crashes. I believe that it is related to dovecot indexes. How to reproduce: Inside a Maildir folder without any indexes yet, compress a message with bzip2 and tryes to access it. At my server is showed the error: Jun 24 00:18:20 maildev dovecot: IMAP(xxx@xxx): FETCH for mailbox Trash UID 1 failed to read message input: No such file or directory Jun 24 00:18:20 maildev dovecot: IMAP(xxx@xxx): Disconnected: BUG: Unknown internal error bytes=329/1050 When I did the same with gzip compression it works as expected (opening the message and creating dovecot indexes). (version, 1.1.16) Best Regards, Fernando

[Dovecot] strange quota behaviour with dovecot 1.1.7
by listacc＠gmx.de 28 Jun '09

28 Jun '09

Hello! I´m running dovecot 1.1.7 (which is the most recent binary of openSuSE 11.1 repository) with Postfix, MySQL and Postfixadmin. Now I´m trying for some days to get quota working, but I get some strange behaviour and I was not yet able to figure out where the error in my configuration is. Quota information is inserted by postfixadmin into a MySQL database. It seems that dovecot is reading this information correctly - when a mailbox is filled up and gets over-quota, further emails are rejected. But then, if I want to increase the quota for this filled-up mailbox in postfixadmin, postfixadmin correctly changes the quota information in MySQL table. After growing quota, mails to the account are accepted again. But my Thunderbird with Quota plugin continues showing the old quota setting. When more mails are sent to this account, it shows a quota > 100%. If I look into the "mailboxsize" file of this account, it still shows the old quota value before I raised it. If I delete the entry in mailboxsize, dovecot writes the old value in again. Seems that dovecot isn´t looking in the MySQL table (but it did after creating the account). But why are mails accepted again if dovecot is not recognizing the raised quota?? If I try now, as a user, to delete mails from the "overfilled" Inbox, it is denied with a "quota exceeded" message. But I´m able to send further mails to this account. The only way to get the account working properly again is to delete the messages directly on the server´s filesystem. I´m very grateful for every hint! regards, Andreas ------------- dovecot -n: # 1.1.7: /etc/dovecot/dovecot.conf # OS: Linux 2.6.27.23-0.1-default x86_64 openSUSE 11.1 (x86_64) ext3 base_dir: /drbd/mail/var/run/dovecot/ log_path: /var/log/dovecot.err info_log_path: /var/log/dovecot.info protocols: imaps managesieve listen(default): * listen(imap): * listen(managesieve): 192.168.1.8:2000 ssl_listen(default): *:993 ssl_listen(imap): *:993 ssl_listen(managesieve): ssl_cert_file: /etc/ssl/certs/imap.domain.crt ssl_key_file: /etc/ssl/private/imap.domain.key verbose_ssl: yes login_dir: /drbd/mail/var/run/dovecot//login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(managesieve): /usr/lib/dovecot/managesieve-login max_mail_processes: 2000 mail_max_userip_connections(default): 30 mail_max_userip_connections(imap): 30 mail_max_userip_connections(managesieve): 10 first_valid_uid: 5001 last_valid_uid: 5001 mail_location: maildir:/drbd/mail/vmail/%d/%n mail_debug: yes mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(managesieve): /usr/lib/dovecot/managesieve mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(managesieve): mail_plugin_dir(default): /usr/lib64/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib64/dovecot/modules/imap mail_plugin_dir(managesieve): /usr/lib64/dovecot/modules/managesieve managesieve_implementation_string(default): dovecot managesieve_implementation_string(imap): dovecot managesieve_implementation_string(managesieve): Cyrus timsieved v2.2.13 sieve_storage(default): sieve_storage(imap): sieve_storage(managesieve): /drbd/mail/vmail/%d/%n/sieve sieve(default): sieve(imap): sieve(managesieve): /drbd/mail/vmail/%d/%n/dovecot.sieve auth default: mechanisms: plain login cram-md5 user: nobody verbose: yes debug: yes debug_passwords: yes passdb: driver: pam passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: passwd userdb: driver: sql args: /etc/dovecot/dovecot-sql.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 432 user: vmail group: vmail plugin: sieve: /drbd/mail/vmail/%d/%n/dovecot.sieve quota: maildir --- dovecot-sql.conf: (...) password_query = SELECT username AS user, password, '/drbd/mail/vmail/%d/%n' AS userdb_home, 'maildir:/drbd/mail/vmail/%d/%n' AS userdb_mail, 5001 AS userdb_uid, 5001 AS userdb_gid FROM mailbox WHERE username = '%u' AND active = '1' (...) user_query = SELECT '/drbd/mail/vmail/%d/%n' AS home, 'maildir:/drbd/mail/vmail/%d/%n' AS mail, 5001 AS uid, 5001 AS gid, concat('*:storage=', quota, 'B') AS quota_rule FROM mailbox WHERE username = '%u' AND active = '1' --- mysql> select quota from mailbox; +-----------+ | quota | +-----------+ | 512000000 | | 512000000 | | 512000000 | | 512000000 | | 512000000 | | 512000000 | | 512000000 | | 512000000 | | 512000000 | | 30720000 | | 30720000 | +-----------+ 11 rows in set (0.00 sec) -- GRATIS für alle GMX-Mitglieder: Die maxdome Movie-FLAT!

[Dovecot] POP3 flag updates

Why does Dovecot add \Seen flag for mails that have been RETRed? Does anyone really want to use this feature? I can't remember why I implemented it originally, perhaps it was just "because other servers do that too". I'm thinking about at least changing pop3_no_flag_updates=yes to be default. There's also of course pop3_enable_last setting to enable LAST command which was removed from POP3 specs. That requires knowing the last RETRed mail, so I guess I should add a check that it can't be enabled without pop3_no_flag_updates=no.

[Dovecot] Spliting Folders for Efficiency
by Daniel Watts 28 Jun '09

28 Jun '09

Dear Timo, Would there be any sense in giving Dovecot the option to split folders into multiple subfolders when they reached a specified size (probably message count) limit? Dovecot would monitor folders and when they reached, say, 10,000 messages, silently split the folder on the filesystem to ensure that access remains fast. I know that Dovecot scales very well but this would give practically unlimited storage capability and also keep things fast. You could even have it so that the latest 100 messages are kept in their own folder for fast access. .Folder.new .Folder.cur .Folder.tmp could become: .Folder__1.new .Folder__1.cur .Folder__1.tmp and .Folder__2.new .Folder__2.cur .Folder__2.tmp with Dovecot merging them before display as just "Folder" within the mail client. This could be further extended so that Dovecot could be configured to store 'old' message folders in a separate location. We could then have slower+cheaper+larger storage mounted so that 'old mail' does not take up the expensive local SCSI disks on the machine. Mail from 2 years ago is much less likely to be accessed than mail from the last week. This would provide very neat behind-the-scenes archiving functionality. Looking forward to hearing your thoughts. Best, Daniel -- Squirrelmail Stable 1.4.8 (and developing on 1.5.2) PHP 5.x Hardened with Eaccelerator Apache 2.x Mysql 5.0.x Imapproxy over Dovecot 1.0.rc27 with Maildir all running on Gentoo Linux for ~5,000 users.

[Dovecot] Sieve/ManageSieve integration into pkgsrc
by Edgar Fuß 28 Jun '09

28 Jun '09

I'm integrating Sieve (the new one) and ManageSieve into wip/dovecot. Currently, this works as dovecot options because dovecot must be built before sieve can be configured and sieve must be built before managesieve can be configured/built. Now, the question arose what the long-term solution (in pkgsrc) should be. To my understanding, with dovecot 2.0, ManageSieve will no longer need to patch dovecot. But what about both Sieve and ManageSieve depending on doevcot sources in order to build (or on libraries dovecot only builds internally)? The preferred way (for pkgsrc) would be if both Sieve and ManageSieve could be built as stand-alone packages and not needing a dovecot source tree to build. What's the long-term plan for Sieve/ManageSieve in this respect? The pkgsrc infrastructure (intentionally) doesn't like a package depending on anothers package working directory in order to build. So with these cross-dependencies, the only pkgsrc ways to go would be either to build it all as one package with options (that's what I currently do) or extract, patch, configure and build dovecot inside a sieve package.

[Dovecot] dovecot and vmailmgr/qmail mailboxes
by Mij 26 Jun '09

26 Jun '09

Hello folks, Time ago I worked on a patch for dovecot to work with vmailmgr http://mij.oltrelinux.com/net/dovecot-qmail-vmailmgr/ The patch was required because, despite vmailmgr complies with the checkpassword interface supported by dovecot, dovecot snips the mailbox directory returned by the authentication module at colon characters ':'. Incidentally, vmailmgr maps any "name.surname@domain" to "~domain/users/name:surname" (a standard practice in the qmail world, see eg http://www.qmail.org/man/man5/dot-qmail.html at "For security") This path dovecot would then parse as "~domain/users/name". An authentication module can't do anything about it, as this is due to dovecot collecting accounting information in one common buffer, tokenized by ':' separators. I soon stopped updating the patch because I didn't see much point in running indefinitely after releases. However, a bunch of people wrote me over the last years asking for details or updates. Partially for having a similar requirement myself, partially drafted by such feedback, I recently wrote a "compromise" wrapper solution (attached). It does not require patching dovecot (external module) and it's thus (supposedly) durable across dovecot releases; however, it cannot help with the colon problem. The wrapper works as follows: 1) compile and install: # cc -O2 -Wall -o checkvpw-dovecot-wrapper checkvpw-dovecot-wrapper.c # install -s -o root checkvpw-dovecot-wrapper /usr/local/bin 2) edit dovecot.conf, setup the auth section as follows: ============ auth default { mechanism = plain passdb checkpassword { args = /usr/local/bin/checkvpw-dovecot-wrapper } userdb prefetch { } user = root } ============ If "name.surname@domain" wants to be created, the administrator shall instead create the user "namesurname@domain" and an alias "name.surname@domain" pointing to it. This may be conceivable for new installations, but it is not for scenarios where dovecot is to replace another server on top of an existing user base. Of course, it's very desirable to support "." users too. I see that it would require several changes in the code, but I'd like to hear your opinion on this. What about - using a different separator than ":", less common and safer. Could '\0' be one? If not, what about '*'? - as a quicker & dirtier solution, what about allowing escaping? One can modify the auth module to replace ":" with "\:", if dovecot is instructed to avoid tokenizing when a "\" precedes a ":". - as an alternative, dovecot may require the module to chdir() to the mailbox directory instead of returning its path as a string, and subsequently operate locally on mailbox-relative paths. I can't guess how compatible this is with the current design. In the next days, I will publish such wrapper to the webpage. For your convenience, I will invite interested users to show up on this thread; this should help you in assessing how this is interesting for people. bye

That is not right, no matter what. >> No, login_processes_count matters. How? If my understanding is correct, you have extra 3 login processes created to cater to new connections. So with only 3 POP3 users, why should so many login processes be spawned? I can understand 10-15. But 100 definitely indicates either the processes are not dying or something else happening on the system which is causing such high number of login processes. The system definitely needs to be checked for some kind of attack, a rogue process running on the system or something else. Regards --Rao

[Dovecot] dovecot-acl-list not honouring owner / permissions that are set on dovecot-shared
by Stuart Rowan 25 Jun '09

25 Jun '09

Hi, I've just upgraded our dovecot installation from 1.0.15 to 1.1.13. This went smoothly and just worked -- thank you very much for writing such a high performance and robust piece of software. However, we have a shared mailbox that people can subscribe to. After upgrading to 1.1.13 ... dovecot tries to create a dovecot-acl-list file in the top level of this ... but it creates it chown'd to the first logged in user with a umask of -rw- --- --- A. -rw------- 1 userA shared 17179 2009-06-25 11:10 /home/imapshared/SharedMaildir/dovecot-acl-list Everyone else who tried to access the shared folder (and hence dovecot tried to read / update the dovecot-acl-list file) caused an error to be logged to the error.log I changed the permissions (once I realised what had gone wrong) to match those on the dovecot-shared file and all was well as everyone can now read/update it. B. -rw-rw---- 1 imapshared shared 17179 2009-06-25 11:19 /home/imapshared/SharedMaildir/dovecot-acl-list -rw-rw---- 1 imapshared shared 0 2008-04-25 13:20 /home/imapshared/SharedMaildir/dovecot-shared Also from time to time the permissions seem to get changed back on dovecot-acl-list inexplicably to those in situation A -- usually following a restart of dovecot but I haven't been able to reproduce this reliably. This seems like a bug to me ... do you agree / is there a sensible work-around? The declaration in dovecot.conf for the shared namespace sets user specific CONTROL and INDEX locations so that users can independently subscribe to folders and mark messages as read on an individual basis. Many thanks, Stu.

That is not right, no matter what. There is definitely some issue. Once the load increases the system will start timing out on POP3 connections or other network connections, such as IMAP, SSH etc. Better check out the system logs, utilization etc. for any abnormal values.

[Dovecot] Quota_rules ignored
by A. Gideonse 24 Jun '09

24 Jun '09

Today I upgraded to version 1.1.16 of Dovecot (and Sieve), because I wanted to use mailbox quotas. I tried using the instructions on http://wiki.dovecot.org/Quota/1.1 and simular websites for 4 hours now, but it seems that all quota_rules are ignored. Also, whenever I use a '*' in my MySQL query I get the error: 'unknown quota backend'. With the following query the quota from the database is used (if value is not NULL), but the quota_rules are ignored once again: user_query = SELECT maildir AS home, 5000 AS uid, 5000 AS gid, CONCAT('maildir:storage=', quota) AS quota FROM mailbox WHERE username = '%u' Below is my configuration: # 1.1.16: /etc/dovecot/dovecot.conf # OS: Linux 2.6.24-19-virtual i686 Ubuntu 8.04.1 nfs log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s ssl_disable: yes 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(pop3): /usr/local/libexec/dovecot/pop3-login mail_privileged_group: mail mail_location: maildir:/data/vmail/%d/%n mail_debug: yes mmap_disable: yes dotlock_use_excl: no mbox_write_locks: fcntl 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_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 auth default: mechanisms: plain login debug: yes passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: passwd userdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: static args: uid=5000 gid=5000 home=/home/vmail/%d/%n allow_all_users=yes socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: vmail plugin: quota: maildir:User quota quota_rule: *:storage=1G quota_rule2: .Trash:storage=100M Any thoughts on how to solve this problem?

[Dovecot] deliver does not update maildirsize
by ftriboix＠falcon-one.com 24 Jun '09

24 Jun '09

Hello, I have installed postfix 2.5.1 + dovecot 1.0.13 + MySQL and it all works perfectly. I use deliver as the local delivery agent and use IMAP only with maildir mailboxes. I am using virtual mailboxes. Now I wanted to introduce quotas, but I can't manage to make them work. Quota information is retreived from MySQL in userdb requests. I have noticed that the maildirsize file is not updated by deliver when a new mail comes in. I don't know if this is correct or not... It is updated though when I log in. But even then mails are still received without any kind of problem while the mailbox is well over the quota. I tried to add a "-v" option to deliver in postfix's master.cf to debug deliver, but it apparently does not like this option. Please find below my postfix and dovecot's configurations. Thank you very much for any help.

[Dovecot] Dovecot Problem
by Robert Sloan 24 Jun '09

24 Jun '09

Dear Sirs, I was able to migrate successfully from Courier-Imap to Dovecot, Timo I appreciate your help. I have notices that the file /var/log/dovecot.log shows the following: dovecot: Jun 23 15:04:05 Info: imap-login: Login: user=<dtoledo>, method=PLAIN, rip=172.16.10.15, lip=172.16.10.19 dovecot: Jun 23 15:04:06 Info: imap-login: Login: user=<abonilla>, method=PLAIN, rip=172.16.10.14, lip=172.16.10.19 dovecot: Jun 23 15:04:06 Info: IMAP(abonilla): Disconnected: Logged out bytes=59/566 dovecot: Jun 23 15:04:06 Info: imap-login: Login: user=<slopez>, method=PLAIN, rip=172.16.10.14, lip=172.16.10.19 dovecot: Jun 23 15:04:06 Info: IMAP(slopez): Disconnected: Logged out bytes=59/567 dovecot: Jun 23 15:04:06 Info: IMAP(dtoledo): Disconnected: Logged out bytes=1252/34481 dovecot: Jun 23 15:04:07 Info: imap-login: Login: user=<slopez>, method=PLAIN, rip=172.16.10.14, lip=172.16.10.19 dovecot: Jun 23 15:04:07 Info: IMAP(slopez): Disconnected: Logged out bytes=59/567 dovecot: Jun 23 15:04:07 Info: IMAP(framirez): Disconnected: Logged out bytes=1252/34041 dovecot: Jun 23 15:04:08 Info: imap-login: Login: user=<mgomez>, method=PLAIN, rip=172.16.10.14, lip=172.16.10.19 dovecot: Jun 23 15:04:10 Info: IMAP(mgomez): Disconnected: Logged out bytes=1805/66570 dovecot: Jun 23 15:04:13 Info: imap-login: Login: user=<curibe>, method=PLAIN, rip=172.16.10.14, lip=172.16.10.19 dovecot: Jun 23 15:04:15 Info: IMAP(curibe): Disconnected: Logged out bytes=749/351591 Given that there are several domains hosted on the server, how can I configure Dovecot to the log file shows the full user name.

[Dovecot] dovecot-antispam problem with sa-learn
by maxlosblob＠tiscali.it 24 Jun '09

24 Jun '09

Hi all, I just set up a dovecot+postfix+roundcubemail+spamassassin system with virtual users. These applications work fine, I have a problem with the dovecot-antispam plugin. Dovecot is compiled from tarball, version 1.1.16, the plugin is version 1.2. The problem is that when I move messages from or to "Posta indesiderata", which is in antispam_spam list, nothing happens. I have no logs about sa-learn activity in /var/log/maillog, nor in /var/log messages, no matter if I set DEBUG=syslog or DEBUG=stderr. Here are my confs: dovecot-antispam .config BACKEND=mailtrain USER=root GROUP=root DEBUG=syslog DEBUG_VERBOSE=5 PLUGINNAME=antispam dovecot -n # 1.1.16: /usr/local/etc/dovecot.conf # OS: Linux 2.6.18-sblob i686 CentOS release 5.2 (Final) simfs protocols: imap pop3 ssl_disable: yes 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(pop3): /usr/local/libexec/dovecot/pop3-login last_valid_uid: 500 first_valid_gid: 500 last_valid_gid: 500 mail_location: maildir:/var/virtual/%d/%n/Posta mail_debug: 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_plugins(default): listescape antispam mail_plugins(imap): listescape antispam 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 namespace: type: private separator: / inbox: yes list: yes subscriptions: yes auth default: passdb: driver: sql args: /etc/dovecot-sql.conf userdb: driver: static args: uid=500 gid=500 home=/var/virtual/% d/%u plugin: antispam_trash: trash;Trash;Deleted Items;Cestino; antispam_spam: Spam;Posta indesiderata;.Posta indesiderata;SPAM;.SPAM antispam_mail_sendmail: /usr/bin/sa-learn antispam_mail_spam: --spam antispam_mail_notspam: --ham antispam_mail_tmpdir: /tmp Thanks in advance Max Non rinunciare ai tuoi ricordi...Tiscali Photo affronta la crisi con incredibili offerte http://photo.tiscali.it

[Dovecot] v1.2.rc6 released
by Timo Sirainen 24 Jun '09

24 Jun '09

http://dovecot.org/releases/1.2/rc/dovecot-1.2.rc6.tar.gz http://dovecot.org/releases/1.2/rc/dovecot-1.2.rc6.tar.gz.sig I think it's time to get v1.2.0 released soon. There is apparently still one rare crashing bug in virtual plugin, but unless someone can reproduce the bug I'm not going to delay v1.2.0 because of it. The release plan is: - Release v1.2.rc7 next Friday (assuming there have been some fixes) - Release v1.2.0 the next Monday I'll be giving a Dovecot talk in Berlin on July 2nd, and I really want to have v1.2.0 released by them. So July 1st is the absolute final deadline for v1.2.0. :) Changes since rc5: * imap proxy: Pass through to client unexpected untagged replies from remote server (e.g. alerts). * Solr: Don't use "any" copyfield, it doubles the index size. * mail_location: Allow using ":" characters in dir names by escaping it as "::". - mbox: Don't crash with invalid From_-lines. - IMAP: Don't crash if IDLE command is pipelined after a long-running UID FETCH or UID SEARCH. - ACL / shared mailbox fixes - Some metadata files were incorrectly getting 0666 permissions.

[Dovecot] courier-imap 2 Dovecot Migration
by Odhiambo ワシントン 24 Jun '09

24 Jun '09

I have a question about migration from courier-imap. I have a server running courier-imap which I'd like to change to dovecot. The problem at hand is that there are POP3 users as well as IMAP4 users.Some of the POP3 users have the option to "leave a copy of the message on the server" set in their MuAs. Is it possible to migrate from courier-imap --> Dovecot and not have these people re fetching all their old e-mails all over again? -- Best regards, Odhiambo WASHINGTON, Nairobi,KE +254733744121/+254722743223 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ "If you have nothing good to say about someone, just shut up!." -- Lucky Dube

[Dovecot] tcp_wrappers
by listmail 23 Jun '09

23 Jun '09

Hi, I've just started using Dovecot (v1.1.14), and I'm noticing a lot of dictionary attacks. I searched through the documentation and the mailing list archives hoping to find support for tcp_wrappers (hosts.deny) support. I did find some suggested patches in the list from last year, but as far as I can tell, there is no support in the released versions. Is this implemented and undocumented, or just unimplemented? I would be surprised to find it unimplemented in such an otherwise sophisticated project. Thanks in advance, --Bill

[Dovecot] A X-Mailbox header?
by Alessandro Ranellucci 23 Jun '09

23 Jun '09

Hi all, I'm waiting for the virtual mailbox feature in order to make a single POP3 access to retrieve messages contained in all my mailbox folders. This is because I use webmail and other IMAP clients but my main workstation uses a POP3-only client. I was wondering if there's a way to keep the name of the folder containing each message while retrieving via POP3. I guess this could be done by dynamically adding a header to messages at retrieval time. Is there a feature for this or a plugin API? Otherwise I was thinking about modifying the messages themselves on the server using a script. However, such a script would need to be run when a IMAP user moves a message to a folder and I believe Dovecot doesn't provide a trigger/hook mechanism. I also don't know if modifying stored messages is allowed since it could break some caching/hashing mechanism. Do you have any idea for this? Thanks in advance and thanks to Timo for the great work! - alessandro.

[Dovecot] CRAM-MD5 authentication but plain-md5 password storage.
by Richard 22 Jun '09

22 Jun '09

Hi all, Got a question on configuring dovecot, I'm still new at this so I might be doing this all wrong. I want dovecot to authenticate the mail client using CRAM-MD5 so I've setup the config in dovecot.conf: auth default { mechanisms = cram-md5 passdb sql { # Path for SQL configuration file, see doc/dovecot-sql-example.conf args = /etc/dovecot/dovecot-sql.conf } <snipped> } In my dovecot-sql.conf I've setup the password scheme to be: default_pass_scheme = MD5 Somehow this does not work, the error I see in the logfile is: auth-worker(default): password(info(a)richard5.tld,127.0.0.1): Requested CRAM-MD5 scheme, but we have only MD5 Is there a way to get this working or does this feature only works with passwords stored in plain text ? Thanks! Richard

[Dovecot] dedup in dovecot?
by Roy Sigurd Karlsbakk 22 Jun '09

22 Jun '09

Hi all Deduplicating data is not really a new thing, but quite efficient in mail systems where an email with an nMB attachment may be sent to multiple recipients. This might call for deduplicating data. Is there a way to do this, or is it far off? If I understand the system correctly, usually an MTA is calling dovecot on every single message, meaning the message itself won't necessarily be a duplicate in terms of headers (BCCs and so on). Would it be possible to dedup the content in terms of using separate files for the header and content and then deduping this with hard or symbolic links? Sorry if this is an old question, but I couldn't find anything about it. roy -- Roy Sigurd Karlsbakk (+47) 97542685 roy(a)karlsbakk.net http://blogg.karlsbakk.net/ -- I all pedagogikk er det essensielt at pensum presenteres intelligibelt.

[Dovecot] Dovecot v1.2 share user Maildir problems with %%h
by Steffen Kaiser 22 Jun '09

22 Jun '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, I'm using Dovecot v1.2 9133:f65112bd90b3 with attached config and try to share user Maildirs. The ACLs are working. However the %%h gives me head aches, well, the location in general: I've copied the default mail_location and changed its CONTROL and INDEX settings: namespace shared { ... location = maildir:%%h/Maildir:CONTROL=/var/cache/dovecot/%i/control/shared/%%u:INDEX=/var/cache/dovecot/%i/index/shared/%%u } Now the first wows are that: a) IMAP insists to connect to $install_prefix/var/run/dovecot/auth-master instead of /var/run/dovecot/auth-master used by deliver. My workaround was to symlink /var/run/dovecot/ to $install_prefix/var/run/dovecot/ b) This socket needs to be r/w for every user, which is a security risk as mentioned in the conf and the default permission is 0600. For deliver I changed the socket attr to permission 0660 and group=mail; for making %%h work I added mail_access_groups=mail c) The user's mailbox is not found still, because: 2009-06-17 15:04:57 auth(default): Info: master in: USER 1 testusr/INBOX service=internal 2009-06-17 15:04:57 auth(default): Info: auth(?): Invalid username: testusr/INBOX 2009-06-17 15:04:57 auth(default): Info: userdb(?): Username contains disallowed character: 0x2f 2009-06-17 15:04:57 auth(default): Info: master out: NOTFOUND 1 The imap process passes the mailbox to the authentificator, too. Also, it changes the '.' to '/', although rawlog has: select "shared.testusr.INBOX" If I allow "/" as userchar, I get: 2009-06-17 15:43:00 auth(default): Info: ldap(testusr/INBOX): Unknown user 2009-06-17 15:43:00 auth(default): Info: master out: NOTFOUND 1 It reallt requests the data of user "testusr/INBOX". d) If I use location = maildir:/home/%%u/Maildir: instead of %%h/Maildir, things work _except_ that some user's %%h != /home/%%u . ============== Basically I have yet another problem with location in the user-share namespace: Because one can override the default mail_location for each user, I did so for some users. Some of them even do not have the Maildir. That leads to the problem, that I need one shared namespace for each location template. There had been a suggestion of a special user-shared namespace a while back. How about to add the base location in the shared-mailboxes.db? So instead of "1" the value is the base of the shared location, e.g. maildir:/local/testuser or maildir:/home/user/Maildir..., and some %%? token takes the string from there. Because the path is known from the db now, the other problems mentioned above do no longer apply.

That is the problem, fetchmail just forwards it to port 25 (I think) and I need to work out what to put between fetchmail and dovecot in order to get the mail into the correct folders... And I am just going around in circles on this at the moment. Any hint would be appreciated! Thanks, Michael

[Dovecot] auth_cache multiple passwords ?
by Geoffroy Desvernay 22 Jun '09

22 Jun '09

Hi, First, thanks Timo and Stefan for this great IMAP/Sieve implementation... We are using 1.1.16+cmu_sieve/managesieve additions for now (following releases since ~ 1.0.1). We have a specific problem here with auth-cache: We use direct imap/sieve connection from different clients, using LDAP password: everything is fine. The problem appears with our webmail access using a web-SSO system (jasig's CAS), using one-time-tickets as password for imap connections (checked by pam_cas module for now). For a single webmail connection par login, it work, thanks to cache_key using client's IP. But for multiple use of the same login in the webmail, there are more than one 'password' valid at a time… What may be the 'correct' solution: - patching auth-cache.c (auth_cache_lookup function ?) - writing a different login backend ? - ??? Hope I'm clear enough… -- geoffroy desvernay Ecole Centrale de Marseille

[Dovecot] dovecot-acl file questions
by Steffen Kaiser 22 Jun '09

22 Jun '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, playing around with Dovecot's v1.2 ACLs I wondered about some things about the dovecot-acl files: + They are created within the Maildirs, as described in http://wiki.dovecot.org/ACL. But why? Shouldn't they belong to the CONTROL= directories? So it is more compatible with filesystem quota. + They have 0666 permissions, but all other files (e.g. when I create a new mailbox) have 0660 permissions. Are the permissions selected explicitly to allow "a"-right for other (system) users? + When one removes all rights, the size of the file drops to zero. The wasted space is no great deal; but how much processing is wasted if such file is present? I mean, the log says that the files are opened very regularily. Would it help to remove zero-size files?

[Dovecot] Corrupted index cache file issues (Corrupted physical size)

The maildirs are migrated from a previous courier server. I've tried searching the archives and can't find anything related to this error. Could someone shed some light on it? Other than the error messages, I'm not aware of anything being affected, but I'd like to be sure of it Some info about the configuration: Maildirs are accessed via NFS, related settings are mmap_disable: yes mail_nfs_storage: yes mail_nfs_index: yes lock_method: dotlock Regards, Brent

[Dovecot] dovecot and ntp: Fatal: Time just moved backwards
by Arno Wald 22 Jun '09

22 Jun '09

Hallo, I am running dovecot on a PC (a workstation) to have a mail client independent storage for my mails. Now I would like to have the system clock set correctly by using ntpd or ntpdate (using debian/sid). The problem is, that the PC is not online at boot time, but is set online on demand manually using "pon" to start the pppd later. So ntpd cannot sync the time on boot time before dovecot gets started. First I was using ntpdate that was started in ppp's if.up.d/ directory. This tool does set the time very hard instead of just slightly shifting some milliseconds. So dovecot did stop itself, reporting: "Fatal: Time just moved backwards by 118 seconds. This might cause a lot of problems, so I'll just kill myself now." So I have tried ntpd as I thought it shifts the time in smaller time deltas. But this takes much time (several seconds) when booting, giving up on all configured servers, because they are not reachable when booting (as going online later manually). This turns off ntp functionality because ntpd does think that all servers are unreachable for ever. (I have tried a command "dynamic" in ntp.conf but this did not change anything and ntpd reports it to be obsolete.) My idea now is to not start ntpd on system boot, but only on if-up. But this brings up the same fatal error of dovecot as ntpd seems to hardly set the time, too. The only idea I have left is to stop dovecot, start ntpd and then start dovecot again on if-up. Is there a more elegant way to use dovecot and ntpd on a manually dialed in PC? Thanks, Arno

[Dovecot] cross compiling (arm)
by Stephen Feyrer 21 Jun '09

21 Jun '09

Hi. I'm trying to cross compile dovecot. My desktop machine is an AMD64 box with bells and whistles. The ARM based machine is a network attached storage box. When I run "make" always get x86_64 binaries. My OS is Gentoo, so I have been able to build using emerge a variety of other programs from source. What am I doing wrong here. (Gentoo doesn't have Dovecot for the arm) I run: ./configure --prefix=/opt --target=armv5tel-softfloat-linux-gnueabi host=armv5tel-softfloat-linux-gnueabi --build=x86_64-pc-linux-gnu --cache-file=config.cache These are some values from config.cache which I think are pertinent: ac_cv_build=${ac_cv_build=x86_64-pc-linux-gnu} ac_cv_c_compiler_gnu=${ac_cv_c_compiler_gnu=yes} ac_cv_env_build_alias_set=set ac_cv_env_build_alias_value=x86_64-pc-linux-gnu ac_cv_env_host_alias_set= ac_cv_env_host_alias_value= ac_cv_env_target_alias_set=set ac_cv_env_target_alias_value=armv5tel-softfloat-linux-gnueabi acl_cv_path_LD=${acl_cv_path_LD='/usr/x86_64-pc-linux-gnu/bin/ld -m elf_x86_64'} lt_cv_path_LDCXX=${lt_cv_path_LDCXX='/usr/x86_64-pc-linux-gnu/bin/ld -m elf_x86_64'} lt_cv_sys_lib_dlsearch_path_spec=${lt_cv_sys_lib_dlsearch_path_spec='/lib /usr/lib /usr/local/lib //usr/lib32/opengl/nvidia/lib //usr/lib64/opengl/nvidia/lib /lib /usr/lib /lib64 /usr/lib64 /usr/local/lib64 /lib32 /usr/lib32 /usr/local/lib32 /usr/x86_64-pc-linux-gnu/lib /usr/lib/gcc/x86_64-pc-linux-gnu/4.3.2 /usr/lib/gcc/x86_64-pc-linux-gnu/4.3.2/32 /usr/lib/gcc/x86_64-pc-linux-gnu/4.2.3 /usr/lib/gcc/x86_64-pc-linux-gnu/4.2.3/32 /usr/lib/gcc/x86_64-pc-linux-gnu/4.1.2 /usr/lib/gcc/x86_64-pc-linux-gnu/4.1.2/32 /usr/lib64/nspr /usr/lib64/nss /usr/lib64/seamonkey /opt/blackdown-jdk-1.4.2.03/jre/lib/amd64/ /opt/blackdown-jdk-1.4.2.03/jre/lib/amd64/native_threads/ /opt/blackdown-jdk-1.4.2.03/jre/lib/amd64/classic/ /opt/blackdown-jdk-1.4.2.03/jre/lib/amd64/server/ /usr/kde/4.1/lib /usr/kde/4.1/lib64 /usr/kde/4.1/lib32 /usr/kde/4.2/lib /usr/kde/4.2/lib64 /usr/kde/4.2/lib32 /usr/lib64/qca1 /usr/lib64/qca2 /usr/lib/qt4 /usr/lib64/qt4 /usr/lib32/qt4 /usr/qt/3/lib /usr/qt/3/lib64 /usr/qt/3/lib32 /usr/games/lib /usr/games/lib64 /usr/games/lib32 /opt/flash-libcompat /usr/lib64/fltk-1.1 /usr/lib32/libstdc++-v3/ '} lt_cv_sys_lib_search_path_spec=${lt_cv_sys_lib_search_path_spec='/usr/lib/gcc/x86_64-pc-linux-gnu/4.3.2 /usr/lib64 /lib64 /usr/x86_64-pc-linux-gnu/lib'}

[Dovecot] 1.1.16 stops authenticating users after several days
by Juergen Obermann 19 Jun '09

Hello, we use dovecot v1.1.16 on two servers with Solaris 9. This week both suddenly stopped authenticating users. The first server was startet on Jun 2 and ran until Jun 18 and the other startet on Jun 3 and failed on Jun 15. Both generated then lots of error messages, three for every user that attemps to login, looking like that: Jun 15 08:35:23 minerva dovecot-auth[20831]: [ID 401707 user.error] open_module: /usr/lib/security/pam_unix_account.so.1 failed: ld.so.1: dovecot-auth: fatal: /usr/lib/security/pam_unix_account.so.1: open failed: No such file or directory Jun 15 08:35:23 minerva dovecot-auth[20831]: [ID 487707 user.error] load_modules: can not open module /usr/lib/security/pam_unix_account.so.1 Jun 15 08:35:23 minerva dovecot: [ID 107833 local0.error] auth-worker(default): pam(gp1071,134.176.2.89): pam_acct_mgmt() failed: Dlopen failure The file /usr/lib/security/pam_unix_account.so.1 was still there and had not been changed.

[Dovecot] compiling dovecot-1.2-sieve-0.1.5 with the latest dovecot-1.2.rc5
by Tim Traver 19 Jun '09

19 Jun '09

Hi all, ok, downloaded dovecot-1.2.rc5 and compiled it with no problem. Then, I went to compile the latest dovecot-1.2-sieve-0.1.5 with it, and got the following error : mail-raw.c: In function 'mail_raw_init': mail-raw.c:119: error: 'NAMESPACE_FLAG_INTERNAL' undeclared (first use in this function) mail-raw.c:119: error: (Each undeclared identifier is reported only once mail-raw.c:119: error: for each function it appears in.) *** Error code 1 In looking around, I noticed in a changed log dated last month, that the NAMESPACE_FLAG_INTERNAL was moved to be two separate flags "_NOQUOTA and _NOACL"... But I think that the author of dovecot-1.2-sieve-0.1.5 hasn't made the change to handle that... So, first of all, I guess I would just like to bring it to the authors attention if it hasn't been already, and second, what is the last rc version before that change so I can actually get things to compile? Thanks, Tim.

[Dovecot] quota.
by Mauro 18 Jun '09

18 Jun '09

Hallo. Sorry for may bad english. I'm running dovecot 1.0.15 on a debian lenny system. I've set quota plugin and, under section plugin, I've set: quota = maildir quota_rule = *:storage=50M quota_rule2 = Trash:storage=10%% quota_warning = storage=95%% /usr/local/bin/quota-warning.sh 95 quota_warning2 = storage=80%% /usr/local/bin/quota-warning.sh 80. For some accounts the quota limit works well. When I send mail I receive a rejected mail for quota exceeded. For some other accounts it doesn'work despite they have passed the 50M storage limit. Why?

[Dovecot] Question about "target is inferior" type of message
by Michael Durket 17 Jun '09

17 Jun '09

We're converting UW-IMAP users here to dovecot. Some of them have seen the error message issued when Thunderbird clients try to delete folders and I understand what's going on (from previous postings) that Dovecot doesn't support mbox subfolders within folders. What puzzles me is that many of these users already have folders within folders (I've found typically 2 levels of nested folders within their main Mail directory). And they're not complaining that they can't read the messages in those folders. If UW-IMAP supposedly never supported this for mbox format, and Dovecot doesn't support it, how is this possible under Dovecot? (We don't have any maildir format mailboxes here at all).

[Dovecot] enourmous amount of disc writes
by Rainer Sigl 17 Jun '09

17 Jun '09

Hi List, on my mailserver (exim4, dovecot 1.0.0, postgresql, ubuntu dapper, about 500 users) I record an enourmous amount of disc writes (up to 18000 blocks written each second) in the time where most of users are active. This IO activity causes wait-states on the disc interface (RAID5) and finally slows down my mailmachine. Is there a explanation for these disc writes respectively is there a possibility to minimize this activity. Stopping Dovecot on this machine causes stopping most of the disc activity.

[Dovecot] v1.2.rc5 imap ignores configuration reloads

Hi Timo, after changing the mail_executable in the imap {…} section I have to restart Dovecot v1.2.rc5, otherwise the changes are not accepted. With Dovecot v1.1.x (tested with v1.1.11 and v1.1.16) it's enough to send a SIGHUP to the dovecot process. Regards, Pascal -- The trapper recommends today: c01dcofe.0916521(a)localdomain.org

[Dovecot] Authentication cache, failure to login after changed password
by Tom Sommer 16 Jun '09

16 Jun '09

Hi, I have an issue with the authentication cache. When a user changes his password, the cache doesn't seem to get flushed. Meaning the user is unable to log in to his IMAP account after changing his password. Flow: - Log into IMAP account using pass1 - Approved - Stored in auth cache - Change password to pass2 in MySQL - Log into IMAP account using pass2 - Access is denied - Restart dovecot - Log into IMAP account using pass2 - Approved I'd really like to continue to use the auth cache, is there any solution to the above? perhaps a way to debug the cache and auth process? I wasn't able to activate auth_debug without restarting Dovecot and solving the problem. Using version 1.1.1, MySQL userdb, with "nopassword=Y". Maybe it's due to nopassword? Thanks -- Tom

[Dovecot] LAYOUT=fs vs LAYOUT=maildir++ and quota
by Ezequiel Alfíe 16 Jun '09

16 Jun '09

Hi everyone. I'm confused about LAYOUT=fs... Does using LAYOUT=fs breaks maildir++ quota, if I use this quota scheme? What are the advantages anyway of using LAYOUT=fs vs LAYOUT=maildir++ ? (it's not important in my case if users can't create folders with dots '.') Thanks in advance, Ezequiel

[Dovecot] shared folders in v1.2 with one uid per user
by Ezequiel Alfíe 16 Jun '09

16 Jun '09

Hello everyone. I'm new to dovecot and I'm setting up a server for one domain only. I have not yet decided whether I will be using one uid per user or one uid for all of them. What are the steps for correctly setting up shared folders with acls if I choose one uid per user? What advantages or disadvantages has setting one uid for all users vs one uid per user, considering I wish to setup shared folders (including security, performance, etc) ? Thanks in advance, Ezequiel

[Dovecot] Multiple mail locations for a single user
by Ross Burton 16 Jun '09

16 Jun '09

Hi, I use offlineimap to cache my remote IMAP mail for my multiple accounts (personal, work, etc) to several maildirs locally. At the moment in my mail client I'm using Dovecot to access one of the maildirs via IMAP, and then direct maildir access for the others. This is suboptimal however because my clients direct maildir support isn't great. Is there any way to let me access all three maildirs through dovecot? I'm guessing that I can do this with namespaces but I'm not sure. Any suggestions and pointers? Cheers, Ross -- Ross Burton mail: ross(a)burtonini.com jabber: ross(a)burtonini.com www: http://burtonini.com

[Dovecot] Archiving feature
by Romer Ventura 16 Jun '09

16 Jun '09

It would be nice to have some sort of archiving feature on which dovecot can save emails older than N+1 months to either a remote Dovecot server with MySQL as storage or a separate instance of Dovecot running on the same server but storing the emails in MySQL Is any of this possible now, or in the works...?

[Dovecot] IMP reading entire mailbox
by Chris O'Regan 16 Jun '09

16 Jun '09

We have been noticing a constant hum of traffic between our IMAP server (Dovecot v1.1.14) and our filers over the past several days. I have narrowed it down to one particular user who has been logged in to IMP/Horde since the problem began (he hadn't logged since we upgraded to Dovecot a week before). IMP is periodically checking this user's mail every five minutes. Each time it does, the his entire mailbox is being read. I initially thought it might be an indexing problem since I am also seeing messages such as this in the logs: Corrupted index cache file /local/data/dovecot/indexes/mail/X/XXXXXXXX/.imap/delivery.log/dovecot.index.cache: Broken MIME parts for mail UID 30880 But the in/out bytes being logged by Dovecot indicate that the entire contents of his mailbox are being sent to the client. That is, this user has a particularly large mailbox (~500M) and about 500M are being sent to IMP every five minutes. (Actually, what is the meaning of the above message? He's the only user logging it.) The user does have some filters defined in IMP, but I can't imagine that it would try to apply them to the entire mailbox each time it is accessed. Surely it would only apply the filters to new messages, right? But I can't think of any other reason why we would be seeing this behaviour, and only for this user. I have not yet contacted the user as I need something to tell him other than "you're a bandwidth hog". I think the next step is to ask him to disable his filters, but I would prefer not shooting in the dark. This user alone is adding about 50Mbps of bandwidth; between the time we upgraded to Dovecot (from uw-imap) and he logged in, we were witnessing a huge drop in traffic. He's ruining our graphs! ;-) Seriously, if anyone has some ideas, please let me know.

[Dovecot] Dovecot v1.2.rc5 dbox file permissions
by Pascal Volk 16 Jun '09

16 Jun '09

Hi Timo, I've just setup Dovecot v1.2.rc5 and switched the mailbox format of one account to dbox. Therefor I've created an empty directory, called dbox, with access mode 0700, like the user's home directory. After the IMAP login with Thunderbird some dboxes was created. All permissions were set fine (0700 / 0600), except the permissions for the files: * ~/dbox/mailboxes/$FOLDERNAME/dbox-Mails/dbox.index * ~/dbox/mailboxes/$FOLDERNAME/dbox-Mails/dovecot.index.log Those files have the access mode 0666.

[Dovecot] mixing dovecot and non-dovecot access to mail
by Michal Szymanski 16 Jun '09

16 Jun '09

Hello, I have recently installed Mailscanner/postfix for the mail server and dovecot for (mainly remote) access to email (via T'bird etc. and/or Webmail). Most users still use text mail clients (mutt, pine, some still old elm) while in the office. These clients access mail (both incoming at /var/mail/ and users' private folders in ~/Mail) directly. I wonder whether this mixing of dovecot and non-dovecot access can make any problems, provide, of course, that the users are not using both ways at the same time. AFAIK dovecot makes some indexing. Will it not be confused if the folder is changed and de-sync-ed with the index? regards, Michal. -- Michal Szymanski (msz at astrouw dot edu dot pl) Warsaw University Observatory, Warszawa, POLAND -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

[Dovecot] dovecot-antispam plugin and "Failed to call dspam" message

Hi, I had this working until I recently upgraded Dovecot, and now I'm getting a message back from Thunderbird of "Failed to call dspam." when I attempt to move a message into one of the designated spam folders.

[Dovecot] dovecot-antispam and permissions
by Tom Hendrikx 14 Jun '09

14 Jun '09

hi list, I'm having trouble with a new setup. My server is running postfix (2.5.5), dovecot (1.1.7), dspam (3.8.0). These all seems to work with eachother. When I add dovecot-antispam in the mix, the following problem occurs: New mail arrives, postfix hands the mail to dspam using a content_filter, and dspam clasifies the mail, running as the dspam user. Dspam writes its data away in a sqlite database. Mail then gets reinjected into postfix and delivered to the system user by deliver. When I manually classify a mail using dovecot-antispam, dovecot runs dspam classification as the system user. This gives the error "failed to call dspam" in my client, and the message "dspam[20203]: query error: attempt to write a readonly database: see sql.errors for more details". Since the mentioned sql.errors is owned by the system user and not by the "dspam" user, it seems that the re-classification proces is run as that user, so he has no write access to the sqlite db, which is owned by dspam:dspam. I could fix this by manually changing group ownership to the database, but maybe there is a more generic way to solve this? -- Regards, Tom

[Dovecot] Couldn't open INBOX: Timeout while waiting for lock
by Eric Sammons 12 Jun '09

12 Jun '09

Hi, So I've been through google and the dovecot source and have not yet found a reasonable explanation for the 'Timeout while waiting for lock' error. My customer's configuration is utilizes mbox with the following mbox configs. [snip] pop3_lock_session = yes mbox_read_locks = fcntl mbox_write_locks = fcntl mbox_lock_timeout = 300 [/snip] I see from the source that this error can occur in one of two places: mbox_lock_dotlock() mbox_update_locking() Given my customer is using fcntl locking I automatically assume that it is the later where they are hitting the error. While I see in the source these errors are Temporary Errors; I do wonder what is the specific cause and what should we be looking at to address the errors. One thing we have noticed is that the errors do not occur regulararly. For exapmle, there were no such errors reported on June 9 or June 10; however on June 11 and 12 the errors started to appear. Any direction / pointers are greatly appreciated. Thank you! -- Eric L. Sammons, RHCE

[Dovecot] Dovecot as a (quota) policy server for Postfix
by Wolfram Schlich 12 Jun '09

12 Jun '09

Hi guys, I'm currently experimenting with Postfix, Dovecot and OpenLDAP to setup a mail server hosting virtual users. The standard stuff works fine so far. The only thing that doesn't work as I'd like it to do is Quota. Currently, Dovecot handles/enforces quota through the deliver LDA. When Postfix tries to deliver a mail to a mailbox that is over quota, the deliver LDA bounces the mail back to the sender. I don't like that. I'd rather prefer Postfix to reject the mail right after receiving the '.' DATA termination line and having checked whether the users quota is or would be exceeded. This could work by writing a small Postfix policy server/daemon that does exactly that Dovecot does: - get the user quota limit from userdb (from LDAP in my case) - get the user quota used (from maildirsize in my case) _ check whether the current mail size + quota used exceed the quota limit and if true, reject the mail Of course this would only work for mails going to a single local recipient address, but most of the time, that's just the case. Now I can re-implement that part of functionality from Dovecot in Perl and write such a small policy daemon that does exactly fit my setup (LDAP + maildirsize). There's one thing I'd like much better, though: What about extending Dovecot by a small policy server module for Postfix? Dovecot already has all the code to do the "over quota" checks and supports a great number of combinations for quota limit and used quota storage. My Postfix instance already kinda depends on a running Dovecot due to Dovecot-SASL for SMTP-Authentication and Dovecot-deliver for mail delivery, so it wouldn't introduce a completely new dependency either. Timo (and all others), what do you think about such a Postfix policy server implemented as a part of Dovecot? -- Regards, Wolfram Schlich <wschlich(a)gentoo.org> Gentoo Linux * http://dev.gentoo.org/~wschlich/

[Dovecot] Dovecot fails to deliver in mail clients

12 Jun '09

Morning I am new to linux and have configured a Postfix + Dovecot Mail server on my SUSE Linux Server 10 SP2 Machine. Postfix works fine I assume as mail gets delivered to user's mailbox or directories. But when I configure a mail client to download mail from the server it finds no mail. When I check the user's mailbox using Webmin mail is delivered. I have also tried to telnet to the server when I do I am able to log in with user's credentials but when I type the list or stat command telnet says there is no mail 0.0Kb. I have tried everything, mail gets delivered to inboxes but telnet and mail clients don't get mail. Please let me know what I am doing wrong Zwelabantu Ngwenya

[Dovecot] unable to send mails via postfix/dovecot SASL
by Michal Szymanski 11 Jun '09

11 Jun '09

Hello, I have a freshly setup postfix/dovecot mail server (after a server upgrade I decided to change my sendmail/popper conf to something more modern :) It mostly works, there is no problem in sending/receiving mails in local network, both using text clients like mutt or pine dealing with the incoming/outcoming mail directly. Also dovecot works fine with SSL authentication from the outside world (home computers etc) but only for reading the mail. I have been struggling for several days already to get postfix/dovecot/SSL trio to work for sending (relaying) mail from the home computers (but also from local network) via my server to the final recipients, using authenticated connections. I followed http://wiki.dovecot.org/HowTo/PostfixAndDovecotSASL hints for the configuration of postfix and dovecot (see output of dovecot -n and postconf -n commands below). I also uncommented "smtps" line in /etc/postfix/master.cf file (otherwise postfix was refusing any connections to secure SMTP port). For a while, I uncommented also "submission" line there but to no success either. Now when I try to send a mail from my home PC, using Thuinderbird 2.0.0.21, with SSL connection configured for outgoing smtp server (port 465), using username/password, it shows "Connected to server..." message but after a minute or so, it fails saying that the connection to SMTP server failed. The server log shows: 11:51:24 sirius postfix/smtpd[15126]: connect from my_home_pc_name/ip Jun 11 11:52:25 sirius postfix/smtpd[15126]: lost connection after UNKNOWN from from my_home_pc_name/ip Jun 11 11:52:25 sirius postfix/smtpd[15126]: disconnect from my_home_pc_name/ip There are no dovecot-related messages in the log regarding such an attempt. I am not sure whether this is dovecot or postfix problem but, being no expert on either of those, I am asking help to resolve this annoying problem. with best regards, Michal. -------------- dovecon -n -------------------------- # 1.0.7: /etc/dovecot.conf ssl_cert_file: /etc/pki/dovecot/certs/sirius.pem ssl_key_file: /etc/pki/dovecot/private/sirius.key login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login mail_location: mbox:~/Mail:INBOX=/var/spool/mail/%u mmap_disable: yes 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/lib64/dovecot/imap mail_plugin_dir(imap): /usr/lib64/dovecot/imap mail_plugin_dir(pop3): /usr/lib64/dovecot/pop3 imap_client_workarounds(default): delay-newmail outlook-idle netscape-eoh imap_client_workarounds(imap): delay-newmail outlook-idle netscape-eoh imap_client_workarounds(pop3): outlook-idle pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: mechanisms: plain login verbose: yes passdb: driver: pam userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix ----------------- postconf -n ---------------------------- alias_database = hash:/etc/mail/aliases alias_maps = hash:/etc/mail/aliases broken_sasl_auth_clients = yes command_directory = /usr/sbin config_directory = /etc/postfix daemon_directory = /usr/libexec/postfix debug_peer_level = 2 header_checks = regexp:/etc/postfix/header_checks html_directory = no inet_interfaces = all mail_owner = postfix mailbox_command = /usr/bin/procmail mailq_path = /usr/bin/mailq.postfix manpage_directory = /usr/share/man masquerade_domains = astrouw.edu.pl mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain, mail.$mydomain, www.$mydomain, ftp.$mydomain, /etc/mail/local-host-names myhostname = sirius.astrouw.edu.pl newaliases_path = /usr/bin/newaliases.postfix queue_directory = /var/spool/postfix readme_directory = /usr/share/doc/postfix-2.3.3/README_FILES sample_directory = /usr/share/doc/postfix-2.3.3/samples sendmail_path = /usr/sbin/sendmail.postfix setgid_group = postdrop smtp_generic_maps = hash:/etc/postfix/generic smtpd_recipient_restrictions = check_recipient_access hash:/etc/postfix/access, permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination, reject_unlisted_recipient smtpd_sasl_auth_enable = yes smtpd_sasl_path = private/auth smtpd_sasl_security_options = noanonymous smtpd_sasl_type = dovecot unknown_local_recipient_reject_code = 550 --------------------------------------------------------------- -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

[Dovecot] Quota over NFS with inode limit
by Patrick Domack 11 Jun '09

11 Jun '09

I tried searching this list, but couldn't find anything related to inode limits except for linux quotas. I wanted to add sieve support for our users, so was attempting to get our email system to use dovecot's deliver lda to handle email, instead of postfix's virtual lda, using maildir mailstore. When I did this, I noticed that emails would get stuck in the queue if a user was over quota, this got fixed when I added in quota support, and set it up to check it using the line: quota = fs:User quota:user:inode_per_mail Now if a user excedes disk space via quota, it's bounced with a message. But if a user excedes their inode quota, it's still tempfail and hangs in the queue till it expires. I just wanted to know if anyone knows about this issue, if I made a stupid mistake or anything else, before I go digging into the source.

Hi all, Dovecot with the "new Sieve" works fine, but 1 - how to have a global script AND 1 script per virtual maibox ? 2 - how to allow a user to change this script (from Thunderbird or Outlook) Thanks JM

[Dovecot] record points outside file error with dovecot revision 9116:9ae55b68cf61
by Jonathan Siegle 11 Jun '09

11 Jun '09

I use mbox with mbox-snarf plugin. I get errors like: dovecot: IMAP(testuser): Corrupted index cache file /full/path/ dovecot.index.cache: record points outside file The errors can be in either folders or INBOX. I put some syslog statements in src/lib-index/mail-cache-lookup.c to help understand this. if (offset + sizeof(*rec) > cache->mmap_length) { mail_cache_set_corrupted(cache, "record points outside file"); syslog(LOG_DEBUG,"mail_cache_get_record rec->size is %d ", rec->size); syslog(LOG_DEBUG,"cache->mmap_length is %d ", cache- >mmap_length); syslog(LOG_DEBUG,"offset is %d ", offset); return -1; } syslog: mail_cache_get_record rec->size is 268595472 syslog: cache->mmap_length is 4096 syslog: offset is 1630760037 Oh I forgot to print off sizeof(*rec). Would that help? Thanks, Jonathan

[Dovecot] SELinux
by Kenneth Porter 11 Jun '09

11 Jun '09

I've temporarily got SELinux set to permissive mode on a fresh install on CentOS 5. It was blocking Dovecot's access to ~/mail because the files were labeled file_t. What's the correct way to label these?

But really, all this leads is that admin has to detect the dovecot termination and simply go and restart it manually -- after some bad thoughts. I think that a config option to restart silently (or simply kill all connected imap/pop3 instances) would be quite reasonable. Basically it is the only thing I don't like in Dovecot... and was even planning to hack the time check out of the code =)) Best wishes Eugene

[Dovecot] Resync quota to mysql script
by Oli Schacher 09 Jun '09

09 Jun '09

I changed some quota options in my dovecot config (eg. excluded folders) but afaik this only affects new mail and there is no magic command to recalculate the quota (or is there?). So I wrote this little python script to do this, maybe someone finds it useful. It can output the sql statements (dovecot 1.0/1.1 and 1.2 format) or just print out quota usage to console.

[Dovecot] Managesieve
by Thomas E. Deutsch 09 Jun '09

09 Jun '09

Hi I've a problem. I've built a new mailserver for our company based on dovecot (1.1.15). At the same time, our company's name has changed. The old mail addresses are forwarded to the new addresses. But I've a problem with sieve. It looks like the sieve filters are only working for the new addresses. But due to the change of the name was not long ago, most of the mails are still sent to the old addresses. What can I do to get filters also working for the old addresses? Configuration of managesieve: protocol managesieve { listen = *:2000 login_executable = /usr/lib/dovecot/managesieve-login mail_executable = /usr/lib/dovecot/managesieve sieve = /home/vmail/%Ld/%Ln/sieve/dovecot.sieve sieve_storage = /home/vmail/%Ld/%Ln/sieve managesieve_implementation_string = Cyrus timsieved v2.2.13 # mail_debug=yes } Regards, Thomas

[Dovecot] Login processes in Dovecot
by Scott Haneda 09 Jun '09

09 Jun '09

I will be deploying Dovecot on OS X shortly. I am looking for clarification on the limits imposed by OS X and sysctl [kern.maxproc]. I understand that it is defaulting to 532, but can be raised to 2500. I believe the OS uses around 100 or so, plus I will have other processes and shells at times. Does Dovecot use one process per user logged in? I find Apple Mail uses about 4 IMAP connections per account. I am not sure that my current number of mail users would be able to be supported on OS X even if I bump up to 2500. Does Dovecot use one process per user logged in differently based on IMAP versus POP? Perhaps this is something that can also be changed in Dovecot, if so, can someone point me to the docs about it, or explain the downsides of going against default behavior. If this is the case, what are my options? Does OS X server have a higher limit in their kernel, or is this across the board? Is it even possible to compile a kernel for OS X with this change, or does that generally mess things up pretty bad? FreeBSD and Solaris seem to have much higher limits, and certainly a much more approachable way of upping those limits. Does anyone know why OS X chose to set these so low, especially given that they do sell server based hardware with a server based OS. Thanks. -- Scott * If you contact me off list replace talklists@ with scott@ *

[Dovecot] Mailbox isn't a valid mbox file

Getting "Mailbox isn't a valid mbox file" on 1.2rc2 after transferring mail from an ancient 0.99.13 system. The first line of the file looks ok. Curiously, it's one of my archival folders of this list. Here's the first header from the top of the file: >From tss at iki.fi Sat May 1 21:48:17 2004 From: tss at iki.fi (Timo Sirainen) Date: Sat May 1 21:54:18 2004 Subject: [Dovecot] 1.0-test2 released Message-ID: <1083437297.21296.19.camel@hurina> X-IMAPbase: 1085322222 20128 Status: RO X-UID: 14065 Content-Length: 226989 X-Keywords: It would be nice if the code that verified the mailbox format would log details about what it disliked.

[Dovecot] General performance of RC5
by Joan 08 Jun '09

08 Jun '09

Hi all, Switiching to RC5, there is a visible decrease in performance to access via IMAP large accounts (>1G) with mutiple mailboxes per accounts. In RC4, there was no delay visible by a human when accessing locally. Now it takes up to 4 or 5 secs. (running on OpenSuse, mysql 5.1.35 for auth, dbox as back end) Anybody experienced also this ? Thanks Joan

[Dovecot] Multiple Dovecot instances over single mail store
by Zohan 06 Jun '09

06 Jun '09

Hi, I need to run two Dovecot instances with totally different authentication configs: first - passwordless, based on client SSL certificate; and second - regular password based (LDAP, passwd etc.). (As far as I know this cannot be achieved with single Dovecot instance; if I'm mistaken, please correct me). My intention is to give clients dual access to their mailboxes: some do own a SSL cert, others do not. I want to know whether it is possible at all. If possible, how do we implement proper concurrent access (locking, etc.) between the two instances to a single maildir-based store? I guess this should be possible since I know Dovecot can operate NFS-backed mail stores, e.g. in a load-balancing cluster setup. Second, is it OK to run the second instance in the same OS (we use Linux)? or chroot'ed or even virtualized solution will work better? Thank you! Zohan

[Dovecot] sieve/dovecot folder separator inconsistency
by Daniel Mayer 06 Jun '09

06 Jun '09

Hi, I'm running dovecot 1.0.15 and ran recently into a problem with the folder separators when using sieve scripts. The server is set to use a slash as a folder separator for all namespaces and announces this correctly when issuing the NAMESPACE command. We are using Ingo (http://www.horde.org/ingo/) of the horde framework to manage our sieve scripts. It creates the folder name / folder path to be used in the sieve scripts based on the result of the NAMESPACE given by the IMAP Server. It therefore created the path separated by slashes ("/"). According to my tests, the delivery agent along with sieve expects the folders to be separated by dots (".") instead of slashes. Is this a correct observation or can this be set using a parameter or something similar? The result of this otherwise inconsistent behavior is that a client who sticks to the provided namespace creates a folder path which cannot be understood by the deliver process. Please let me know if you need any additional information. Thanks, Daniel

[Dovecot] Dovecot under brute force attack - nice attacker
by henry ritzlmayr 05 Jun '09

05 Jun '09

Hi List, optimizing the configuration on one of our servers (which was hit by a brute force attack on dovecot) showed an odd behavior. Dovecot Version 1.0.7 (CentOS 5.2) The short story: On one of our servers an attacker did a brute force attack on dovecot (pop3). Since the attacker closed and reopened the connection after every user/password combination the logs showed many lines like this: dovecot: pop3-login: Aborted login: user=<test>,...... The problem: If the attacker wouldn't have closed and reopened the connection no log would have been generated and he/she would have endless tries. Not even an iptables/hashlimit or fail2ban would have kicked in. How to reproduce: telnet dovecot-server pop3 user test pass test1 user test pass test2 ... QUIT ->Only the last try gets logged. If I enable auth_verbose every attempt gets logged, but if I read the docs correctly this option should only be used for figuring out why authentication isn't working. Question: Is there any way to close the connection after the first wrong user/pass combination. So an attacker would be forced to reopen it? This would be perfect since an easy iptables/hashlimit would avoid such a brute force attack. Any other Ideas? Henry

http://dovecot.org/releases/1.2/rc/dovecot-1.2.rc5.tar.gz http://dovecot.org/releases/1.2/rc/dovecot-1.2.rc5.tar.gz.sig Some small fixes mainly. I guess I'll still have to release rc6 and rc7 after all. I've been a bit busy with v2.0 changes recently. BTW. I'm leaving tomorrow to San Francisco and I'm going to check out what's happening in Apple WWDC next week. * auth_cache_negative_ttl is now used also for password mismatches (currently only with plaintext authentication mechanisms). + Added support for EXTERNAL SASL mechanism. + FETCH X-SAVEDATE can now be used to get messages' save timestamps + deliver_log_format: %s is now in UTF8 - If message body started with a space, some operations could have assert-crashed. - Fixed using LDAP support as a plugin - Fixes to virtual mailboxes.

Under load, we are experiencing the following errors: Jun 4 18:30:59 ug1s02-zone1 dovecot: [ID 107833 mail.error] auth(default): ldap(0202934816(a)ug.smilecoms.com,10.31.3.13): ldap_search() failed (filter (uid=0202934816(a)ug.smilecoms.com)) Server is busy We are authenticating against sun directory server yet see no errors in the directory server and it seems to be under low load. Any ideas if there is something on dovecot we should tune to erradicate this? We are running a web front end on top of dovecot and hence have a lot of login/logout happening as the user navigates around.

[Dovecot] imapmagicplus equivalent?
by Juergen Kreileder 04 Jun '09

04 Jun '09

Hi, is anything like Cyrus IMAP's imapmagicplus option available for Dovecot? If not, would it be possible to implement as a plugin? > imapmagicplus: 0 > Only list a restricted set of mailboxes via IMAP by using userid+namespace syntax as the authentication/authorization id. Using userid+ (with an empty namespace) will list only subscribed mailboxes. It's a quite useful option for clients that don't understand subscriptions. E.g., I don't want to see all of my folders on my iPhone, by using userid+ I can limit them to a useful set. Juergen

[Dovecot] Password environment variable - logging the password
by Donovan Craig 04 Jun '09

04 Jun '09

Hi, We¹re migrating to a Cpanel hosting system. Our passwords are currently stored in MD5. I looked at the post login scripting to be able to start storing the plain text passwords as people login temporarily so we can automate our migration. It seems that the password is not available in the post login environment variables. Is there any way we can get access to the plain text password upon login so we can insert this into our user table? Best regards, Donovan

[Dovecot] Some questions about deliver
by Axel Luttgens 04 Jun '09

04 Jun '09

While investigating Dovecot's deliver with Postfix, I encountered some behaviors making me wonder whether I really understand the purpose of that binary. So, if you allow... This is from Postfix' main.cf: mailbox_command = /usr/local/dovecot/libexec/dovecot/deliver -e -n This is my quick setup for Dovecot: # 1.2.rc4: /usr/local/etc/dovecot.conf # OS: Darwin 9.7.0 i386 protocols: pop3 ssl: no disable_plaintext_auth: no login_dir: /usr/local/var/run/dovecot/login login_executable: /usr/local/dovecot-1.2.rc4/libexec/dovecot/pop3- login first_valid_uid: 2001 mail_location: mbox:~/_mailboxes:INBOX=~/_inbox/mailspool mbox_read_locks: flock mbox_write_locks: flock dotlock mail_executable: /usr/local/dovecot-1.2.rc4/libexec/dovecot/pop3 mail_plugin_dir: /usr/local/dovecot-1.2.rc4/lib/dovecot/pop3 pop3_lock_session: yes pop3_uidl_format: %08Xv%08Xu auth default: passdb: driver: pam args: * userdb: driver: passwd Here is an excerpt from mail.log: postfix/smtpd[4117]: connect from localhost[127.0.0.1] postfix/smtpd[4117]: 163E1CA2675: client=localhost[127.0.0.1] postfix/cleanup[4120]: 163E1CA2675: message-id=<27002A3F-AF44-410D-A500-368D04F5FA9A(a)almbp.local > postfix/qmgr[3232]: 163E1CA2675: from=<testuser(a)almbp.local>, size=2650, nrcpt=1 (queue active) dovecot[4129]: deliver(www): mail_location: mbox: mkdir(/Library/ WebServer/_mailboxes) failed: Permission denied (euid=70(_www) egid=70(_www) missing +w perm: /Library/WebServer) dovecot[4129]: deliver(www): Fatal: Namespace initialization failed postfix/local[4122]: 163E1CA2675: to=<www(a)almbp.local>, relay=local, delay=0.09, delays=0.02/0/0/0.07, dsn=4.3.0, status=deferred (temporary failure) postfix/smtpd[4117]: disconnect from localhost[127.0.0.1] 1. Shouldn't deliver honor the first_valid_uid setting? After all, if some user isn't allowed to login, is that user supposed to receive mail? 2. What exactly is the -e option supposed to do? User _www clearly isn't configured for receiving mail, but Postfix will nevertheless try to deliver the message until maximal_queue_lifetime has expired. From the log excerpt, it appears that Postfix has been led to consider a temporary failure; unless I'm wrong, that's because Postfix didn't receive neither a "D.S.N text" string nor an EX_* fatal return code. From deliver.c, it seems that many calls to i_fatal() are liable to be executed before the -e option is taken into account (through the local variable stderr_rejection). As a result, I'm wondering under which circumstances exactly deliver is liable to return EX_NOPERM, so that Postfix may consider a permanent failure and bounce the message. Note that the question may somehow be re-phrased as: when invoked without the -e option, under which circumstances will deliver send a rejection message? 3. Doesn't failure_exit_callback() in deliver.c tend to merge many (possibly dissimilar) errors into the single EX_TEMPFAIL one? And BTW, is that function guaranteed to be always called with an EX_* value? Seems to be the case, but... ;-) TIA for your patience, Axel

Hi all I am in the process of migrating Courier to Dovecot, am using courier-dovecot-migrate.pl<http://www.dovecot.org/tools/courier-dovecot-migrate.pl>it works fine. I want to migrate each user as they login using post-login script (As i have huge no of users). We are using NFS storage, users are authenticated using mysql, User home directories as passed using variable mail ( usign mysql query). I am trying to execute postlogin script which does the conversion but unable to pass the user home directories . --*/etc/dovecot.conf mail_executable = /usr/libexec/dovecot/postloginscript.sh %h ---* %h ---- for home directory. ---*postloginscript.sh #!/bin/sh /usr/libexec/dovecot/courier-dovecot-migrate.pl --quiet --to-dovecot --recursive --convert $1 # This is for pop3 exec /usr/libexec/dovecot/pop3 ----* When i pass %h as argument its creating "%h" directory and writing dovecot-uidlist and rest the files in %h directory. Its not interpreting the %h and not passing the home directory. Its just passing as it is. Hope i am clear in articulating my problem. Please help. -- Regards Ash

[Dovecot] 1.2.beta1: expire-tool and 'mail_location' setting
by e-frog 03 Jun '09

03 Jun '09

Hi Timo, Trying 1.2.beta1 with expire plugin currently: When I set mail_location = maildir:~/.maildir the expire plugin doesn't delete messages. #: expire-tool --test Info: auth input: system_user=foo Info: auth input: uid=1000 Info: auth input: gid=1000 Info: auth input: home=/home/foo Info: foo/Trash: no messages left I also noticed that above command creates a new but empty directory 'mail' in user's home dir. However using mail_location = maildir:~/Maildir and of course moving the messages to it works. #: expire-tool --test Info: auth input: system_user=foo Info: auth input: uid=1000 Info: auth input: gid=1000 Info: auth input: home=/home/foo Info: foo/Trash: seq=1 uid=4078: Expunge . .

Hello, is the expire plugin usable to delete mails with different settings for each individual user? If i view sample config at http://wiki.dovecot.org/Plugins/Expire it looks like expire-data are related to foldernames. Is it possible to let each user "activate" the expire-plugin for different folders with different settings? Thanks, Andre

http://dovecot.org/releases/1.1/dovecot-1.1.16.tar.gz http://dovecot.org/releases/1.1/dovecot-1.1.16.tar.gz.sig Fixes a couple of bugs in v1.1.15's changes. Hopefully the last v1.1 release before v1.2.0. - v1.1.15 could have crashed if mailbox-closing command was pipelined after a mailbox-accessing command. - v1.1.15's zlib plugin may have caused crashes when fetching INTERNALDATE. - Maildir: If messages had been deleted externally from new/ directory and mailbox was opened with EXAMINE, Dovecot didn't immediately notice that the messages were deleted. - If message body started with a space, some operations could have assert-crashed.

[Dovecot] recipient delimiter and lmtp
by John Fawcett 02 Jun '09

02 Jun '09

I read in the list archives about work in progress on an lmtp delivery agent.As a previous cyrus user where that was the preferred delivery method from postfix, this sounds interesting. I was wondering whether it will handle recipient delimiters. ie will it be able to map user+foo(a)example.com to user(a)example.com? I'm not interested in the delivery into folder stuff, just the plain delivery to inbox. thanks, John

[Dovecot] IMAP labeling sometimes not taken into account
by Olivier Cailloux 02 Jun '09

02 Jun '09

Dear Dovecot list, I recently switched from uw-imapd to dovecot to manage my huge mbox files (about 1 GB). I now observe a very strange behavior, difficult to reproduce reliably, which might be related to some misunderstanding on my part on how either dovecot works or imap labeling works. What I call "labeling" is the fact of marking some e-mail, in my e-mail client (currently Thunderbird), with a label, which can be chosen among five labels (plus the "no-label" case). Evolution also supports labeling. As far as I understood until a few days ago, when I put a label, say, number five, on an e-mail, a keyword "$Label5" is added on the "X-Keywords:" line of the corresponding e-mail in my mbox file. Removing the label simply removes the keyword on the same line. That is, at least, what happened with uw-imapd (not that I have seen that documented somewhere but this is what I observed). The label is thus stored on the e-mail server, not on the client hard disk, which is important for me as I extensively use that feature to sort e-mails, and need to access them from several different places (and find the same labels at the same places, naturally, whatever client I use). Since the change for dovecot, however, things are going strange. Sometimes the labels disappear for some reasons. Sometimes they stay there. And I can't reproduce the behavior, it just seems random. This is very annoying as it totally breaks my e-mail management. Currently there is something strange I can reproduce however, and if someone could explain me what is happening I guess it would be a good step towards a solution. I see a specific e-mail as being labeled in thunderbird, having label number five. I also tried with evolution, accessing the same imap folder, evolution also sees that e-mail as having a label number five. I tried running these clients from my imap server, and I tried thunderbird on a Windows box at home, and every clients agree: this e-mail has a "5" label. BUT when I open the mbox file directly on the imap server (using "less"), and scroll to that given e-mail, I see NO "X-Keywords: " line. How then can the e-mail clients know that this e-mail is labeled? Please note that this behavior does not happen with only one specific e-mail, but I take it as an example of what is strange. In fact I can see, especially at the end of the mbox file (thus the latest e-mails), that plenty of e-mails have either no "X-Keywords: " line or a line with "X-Keywords: " and nothing else, whereas they are seen as being labeled (and indeed I remember having labeled most of those through thunderbird). The former e-mails I checked in the m-box (for example, one month ago) all correctly have an X-Keywords line indicating "$Label5" or other appropriate labels. It seems like dovecot is keeping some track of labeled e-mails somewhere which is NOT in the mbox file, probably related to its indexing capabilities. But I don't know how that works and where these index files are stored, how to purge them and rebuild the index, and so on. Apparently these index files have remembered some e-mails as being labeled (which is good, because I indeed labeled them). But I'd like to know how that works to be able to better troubleshoot why sometimes the label disappear. Note that restarting dovecot does not change the label status of the e-mail, so the status must be stored somewhere on disk and not only in memory. Or is all these labeling stuff some unsupported, non-standard extension to IMAP that only uw-imapd supports? (I hope not because I find it very practical and I'd like to use it with dovecot as well!) Thank you for any help. (Technical informations follow.)

[Dovecot] Capability problems dovecot 2.0
by ja nein 01 Jun '09

01 Jun '09

Hi, I had some problems connecting TB 2.x with dovecot 2.0. TB2 complained about not being an IMAP4 server. TB 3 worked. It seems that dovecot 2.0 doesn't return capabilities when queried. Maybe some wrong config, thoug? Here are the debug logs from TB2 comparing dovecot 2.0 (not working) and dovecot 1.2 (working): Dovecot 2.0: NA:CreateNewLineFromSocket: * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE AUTH=PLAIN AUTH=LOGIN AUTH=DIGEST-MD5 AUTH=CRAM-MD5] Dovecot ready.

[Dovecot] For the record: Postfix+Spamassassin+ClamAV+Dovecot
by James Butler 01 Jun '09

01 Jun '09

Postfix 2.5.5 SpamAssassin 3.2.5 (under Perl 5.10.0) ClamAV 0.95.1 Dovecot 1.2.rc2 works fine on Fedora 10. Installed Dovecot and ClamAV from source and everything else using yum. I'm using the ClamAV plugin for Spamassassin: http://wiki.apache.org/spamassassin/ClamAVPlugin I'm calling Spamassassin with: /etc/postfix/main.cf: mailbox_command = /usr/bin/spamc -f -e /usr/local/libexec/dovecot/deliver Postfix hands off to Spamassassin, which processes ALL mail (not just attachments) through the ClamAV plugin before parsing for spam, and then hands the whole mess off to Dovecot for 'deliver' to handle. How simple is that? Since ClamAV scanns all mail, it might be too processor-intensive for really large mail systems, but it is working great for our 120+ user system with lots of spam coming in. If you're using Procmail or some other preprocessor that can hand off to a pipe, then you could skip the plugin and pipe messages over a certain size (i.e. >1024) to clamd, instead. Enjoy! James

[Dovecot] Namespace delimiter...
by Lenthir 01 Jun '09

01 Jun '09

As RFC3501 (IMAP) say: 'A NIL hierarchy delimiter means that no hierarchy exists; the name is a "flat" name.' How to change delimiter to NIL? We have flat namespaces in our storage. Now I hardcoded this and everything is working, but maybe it is another possibility... -- Konrad

[Dovecot] namespace problem with dovecot 2.0
by reg9009 01 Jun '09

01 Jun '09

Hi all, I've got some namespace problems with dovecot 2.0 again. If I start dovecot 2.0 with same settings of namespace and maildir layout as dovecot 1.2, I don't see my folders above the Inbox. I see them as "INBOX/xxx" in the same root level as my INBOX. If I try to subscribe to the folders, I see them as "INBOX^xxx" (and cannot subscribe). My namespace settings: namespace private { separator = / prefix = "INBOX/" inbox = yes #hidden = yes list = yes subscriptions = yes } I tried nearly every separator/combination, but it won't work. Any ideas (to get it work like dovecot 1.2)? I've got no shared folders/namespaces, etc. Layout is plain Maildir. Regards, Sebastian

[Dovecot] Feature Missing OUTBOX Folder
by Frank Doege 01 Jun '09

01 Jun '09

Hi Dovecot People, i have switched my system from courier-imap to dovecot and iam quite happy with it, the performance is well and i had nearly no problems. One little feature iam missing is in Courier i had a folder called "Outbox" there i could paste mails which i want to sent out. In some networks its not always available to sent mails via port 21, i know i could just set up my email server to another port but it was a nice feature. Is this a big afford or is it just alittle hack ? could it done via a little plugin ? Thanks Timo & all others for the great work ! Frank

[Dovecot] imap cann't read the mail that foxmail send
by wallace0615 01 Jun '09

01 Jun '09

Hi everyone: I use dovecot only as the imap server, For smtp and pop3, I use apache james. The dovecot version: 1.1.14 And the configuration is : protocols: imap ssl_disable: yes login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login mail_location: mbox:/usr/local/edupass/mail/repo/%u:INBOX=/usr/local/edupass/mail/%u auth default: passdb: driver: sql args: /etc/dovecot-sql.conf userdb: driver: sql args: /etc/dovecot-sql.conf I have no porblems to login. When I use "telent host 25" to send a email, dovecot read it no problems. But when I use outlook and foxmail to send a email, dovecot cann't read the email data. I compared the data that using the two way to send, and found the reason: use outlook and foxmail: at the beginning of the eamil data is "From zxjteacher_SP_LZU <zxjteacher_SP_LZU@myserver>"; and if I telnet host 25 to send the mail: at the beginning of the eamil data is "From <zxjteacher_SP_LZU@myserver>", so I delete "zxjteacher_SP_LZU", dovecot read it out. "zxjteacher_SP_LZU" is because that outlook and foxmail need an account name to represent the eamil address. So, anyone ever confront with this situation? Any helps appreciate. Thx.

[Dovecot] Expire Plug-in stopped
by Matt Rude 01 Jun '09

01 Jun '09

Good evening, While working with Dovecot 1.2rc4 on Fedora 10, I have been trying to get the Expire plug-in to auto delete messages for us. When I run the plug-in with the test flag, I receive the following message: /usr/local/sbin/dovecot --exec-mail ext /usr/local/libexec/dovecot/expire-tool --test Info: amy(a)example.com/Trash: stop, expire time in future: 1242953758 All messages were deleted before the expire plug-in was added. I understand that dovecot will only expire messages after they have been in the trash or junk longer then the time in dovecot.conf. So I have let this fail since Monday, but continue to receive the same error. A quick grep for expire from my Dovecot logs doesn't show any output. Also, when I look up this error on google, I see other peaple who's output shows a real date (not 1242953758), how do I know when this date is?

[Dovecot] Assertion failure in maildir-mail.c for gzipped maildir files in 1.1.15
by David S. Madole 01 Jun '09

01 Jun '09

I attempted an upgrade from 1.1.7 to 1.1.15 and encountered an apparent regression in handling gzipped maildir files. I have tried to narrow down the conditions under which it happens and reproduce it with as simple a case as possible. The actual mail application that exposed this problem is Squirrelmail. Starting off with the index files removed from the "Folder" maildir directory: * OK Dovecot ready. 1 login x y 1 OK Logged in. 2 select Folder * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 13 EXISTS * 0 RECENT * OK [UIDVALIDITY 1220278111] UIDs valid * OK [UIDNEXT 14] Predicted next UID 2 OK [READ-WRITE] Select completed. 3 UID FETCH 3 (RFC822.SIZE INTERNALDATE) * 3 FETCH (UID 3 RFC822.SIZE 1085 INTERNALDATE "04-Jan-2004 09:23:45 -0500") 3 OK Fetch completed. 4 UID FETCH 4 (RFC822.SIZE INTERNALDATE) Connection closed by foreign host. The fetch of message 3, which is not gzipped succeeds, but the fetch of message 4, which is gzipped, fails with the following assertion in the log: Panic: imap: user=x, Status: file maildir-mail.c: line 85 (maildir_mail_stat): assertion failed: (fd != -1) Repeating, but first fetching only INTERNALDATE from the gzipped message succeeds, and once that value is cached in the index files, the same query that causes the failure before will now succeed, as it doesn't need to read the gzipped file any more to get INTERNALDATE: * OK Dovecot ready. 1 login x y 1 OK Logged in. 2 select Folder * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 13 EXISTS * 0 RECENT * OK [UIDVALIDITY 1220278111] UIDs valid * OK [UIDNEXT 14] Predicted next UID 2 OK [READ-WRITE] Select completed. 3 UID FETCH 4 (INTERNALDATE) * 4 FETCH (UID 4 INTERNALDATE "02-Dec-2003 10:39:18 -0500") 3 OK Fetch completed. 4 UID FETCH 4 (RFC822.SIZE INTERNALDATE) * 4 FETCH (UID 4 RFC822.SIZE 6035 INTERNALDATE "02-Dec-2003 10:39:18 -0500") 4 OK Fetch completed. 5 logout * BYE Logging out 5 OK Logout completed. Connection closed by foreign host. Now that the value is cached, the same previously failing query will continue to execute fine, as long as the indexes remain in place: * OK Dovecot ready. 1 login x y 1 OK Logged in. 2 select Folder * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 13 EXISTS * 0 RECENT * OK [UIDVALIDITY 1220278111] UIDs valid * OK [UIDNEXT 14] Predicted next UID 2 OK [READ-WRITE] Select completed. 3 UID FETCH 4 (RFC822.SIZE INTERNALDATE) * 4 FETCH (UID 4 RFC822.SIZE 6035 INTERNALDATE "02-Dec-2003 10:39:18 -0500") 3 OK Fetch completed. 4 logout * BYE Logging out 4 OK Logout completed. Connection closed by foreign host. Removing the indexes again, and this time first fetching just RFC822.SIZE first: * OK Dovecot ready. 1 login x y 1 OK Logged in. 2 select Folder * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 13 EXISTS * 0 RECENT * OK [UIDVALIDITY 1220278111] UIDs valid * OK [UIDNEXT 14] Predicted next UID 2 OK [READ-WRITE] Select completed. 3 UID FETCH 4 (RFC822.SIZE) * 4 FETCH (UID 4 RFC822.SIZE 6035) 3 OK Fetch completed. 4 UID FETCH 4 (RFC822.SIZE INTERNALDATE) Connection closed by foreign host. In this case, the assertion fails again. Fetching RFC822.SIZE alone does not populate the indexes in a way that then allows RFC822.SIZE and INTERNALDATE to be fetched, as fetching INTERNALDATE alone does. It's all confusing to me, hopefully this make some sense to others. Let me know if there is other testing I can help with. I'm running on Slackware 12.1 and have reproduced the same issue with both kernel 2.6.24.4 and 2.6.27.7. The filesystem is XFS. The content of the gzipped message does not seem to matter. David

[Dovecot] Missing IMAP folders after Server reboot
by Eoin Kennedy 31 May '09

31 May '09

Hi, Here is the situation, I hope somebody can help me. Our Email server running ubuntu 8.04.1 and dovecot 1.0.10 rebooted, and when it came back up the dovecot config had changed. Prior to the reboot, users stored their emails and folders in /var/mail/~username. Then the config became /var/mail/username for the main Inbox and /home/~username/mail for Folders. Now, none of the folders that users had created in their IMAP account are visible, and their contents are not in the main Inbox file. For example, the Drafts folder was there prior to the reboot, and now it had to be created in /home/username afterwards. These folders were not subfolders of the Inbox, but of the main IMAP root. All users were running Thunderbird as their client. Can they be recovered?

[Dovecot] antispam plugin and MUA-Junk folders
by Steffen Kaiser 31 May '09

31 May '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, I have a configuration problem, that I ignored till now. Many MUAs tag SPAM themselves and move SPAM to a junk folder (Thunderbird uses "Junk"). It is said to not automatically train these mails, but let have an human revise them. Currently, I have configured those folders as "trash" folders for antispam, which means that those messages are essentially lost, because a move into a spam folder will not train them. -> The current antispam plugin ignores moves in and out of trash folders completely. I wonder why the move trash -> SPAM is ignored? If I configure those junk folders as "unsure" in antispam, the situation can happen, that an user selects a spam folder, the MUA identifies junk and moves the messages into its Junk folder. Current implementation would train this move as HAM. How about the following: 1) copy from * into trash or unsure -> not train 2) copy from !spam into spam -> train as SPAM 4) copy from spam or unsure into !(trash or unsure or spam) -> train as HAM 6) else -> not train Bye, - -- Steffen Kaiser -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iQEVAwUBSh0PdHWSIuGy1ktrAQKmaAf/ew1SixCkkWD2V12Jfw3mLcWnUrUSRq/J nsyMkW2//tX74wSJeMjbzlEkxN3dyfJg7f4WviGPdnUp5sqNGuS9lBfHh3ShQHtt 30+mRzVqizmcNEXBFoZXVy1K5hE8p9ssN9avahmUejBVPaSZHD0OjN5h8nFkNMDI XHU2347g03zr1MxejinWyRiKt1MFQyyJ6Y7gXNf6yascWKJA8W6b4Zu/eIH5uEW+ yiMuweaxJOwuGcwqh/qSKZTXnoCLa9rzvd8i/uZGvn7AXoT5u4P5coZkIHrh64U7 oswuYAZwxkmjGNLdGrovZadRJym16BlfVHH5g3Zo7k4nwX+kGRKyug== =9b+n -----END PGP SIGNATURE-----

I have a dumb question, is it possible to use this combination: Synchronising a remote IMAP-server and a local dovecot-IMAP-server by offlineimap (with both types = IMAP), which works very well. But it seems, that my sieve-scripts on the local dovecot server are not recognised by this combination.

hello! on one of my servers (freebsd 7.0-R , Jail) I have a very strange problem I guess its something about LOCKing. some programs have issued with locking: saslauthd[38127] :main : could not lock pid lock file: /var/run/saslauthd/saslauthd.pid.lock saslauthd[38127] :main : fcntl: Invalid argument dovecot: 2009-05-29 03:45:50 Info: dovecot v1.1.15 starting up dovecot: 2009-05-29 03:45:50 Info: Generating Diffie-Hellman parameters for the first time.

[Dovecot] (no subject)
by Patrick Hemmen 29 May '09

29 May '09

Hi, I use a OpenLDAP for authentication. To authenticate a full DN as the user name must be used, like "cn=jim,ou=users,dc=example,dc=com". There are several domains, like example2.com and example3.com. I want to use Dovecot with ldap and authentication binds. For testing I use "auth_bind_userdn = cn=%n,ou=users,dc=%d" and the user name must provide as "jim@example,dc=com". To allow the special chars ("=,") in user name, I extend "auth_username_chars". Now my questions. Exists a real chance to attack the ldap directory with the extended "auth_username_chars"? And it's possible to use authentication binds with the regular "auth_username_chars" and a provided user names like "jim(a)example.com" in my special ldap directory structure? Thanks in advance - Patrick

[Dovecot] Clustering dovecot?
by dovecot＠corwyn.net 29 May '09

29 May '09

Currently I have a mail server running postfix and dovecot with users in mysql. I have Outlook (blich) clients checking IMAP mail on the server. I'd like to build some fault-tolerance into that system in case I have hardware failure. I've read through: http://wiki.dovecot.org/MailLocation/SharedDisk but I feel I need more information. My basic understanding is that I'll need 2 clustered systems running with shared disk space and shared IP. Performance/load-balancing isn't an issue for me, it's just fault-tolerance that I'm worried about. I found a nice long doc for Cyrus IMAP (http://cyrusimap.web.cmu.edu//ag.html) anything similar for dovecot? Rick Rick Steeves http://www.sinister.net "The more I learn, it seems, the less I know."

[Dovecot] expire: mysql table creation error
by John Fawcett 29 May '09

29 May '09

Don't know if anyone found this already (couldn't see anything in the archives about it) but maybe this is useful to someone else who finds the same problem. When following the instructions for setting up expire on v1.2+ for mysql backend at http://wiki.dovecot.org/Plugins/Expire I got the following error: mysql> CREATE TABLE expires ( -> username varchar(100) not null, -> mailbox varchar(255) not null, -> expire_stamp integer not null, -> primary key (username, mailbox) -> ); ERROR 1071 (42000): Specified key was too long; max key length is 1000 bytes that's because it's a utf8 database where every char is 3 bytes so a 355 char index is 1065 bytes. it worked ok with the following modification: mysql> CREATE TABLE expires ( -> username varchar(100) not null, -> mailbox varchar(255) not null, -> expire_stamp integer not null, -> primary key (username, mailbox(200)) -> ); Query OK, 0 rows affected (0.00 sec) but maybe that's not such a good primary key, probably better to do: mysql> CREATE TABLE expires ( -> id integer not null auto_increment, -> username varchar(100) not null, -> mailbox varchar(255) not null, -> expire_stamp integer not null, -> primary key (id), -> key (username, mailbox(200)) -> ); Query OK, 0 rows affected (0.00 sec) John

[Dovecot] dovecot: child xxxx (login) returned error 83 (Out of memory)
by Eric Sammons 29 May '09

Hi, Recently started receiving the error $SUBJECT. Soon after a number of segfault errors are reported for pop3-login. Based on my configuration, I believe I am set up to receive core files; however, my ulimit -c is 0. I have tried setting ulimit -c ... in /etc/init.d/dovecot and I have tried modifying /etc/security/limits.conf. In all cases /proc/[pid]/limits continued to report that my ulimit -c value was 0. What is the best process for capturing a core file from a login process (pop3-login). I have found some similar hits on the web for this; however, none appear to lead to resolution and in most cases the implementation includes imap, mysql, etc...

[Dovecot] Timeout during imapsync
by Craig Jackson 29 May '09

29 May '09

Hi, I'm using Imapsync to sync messages from an Exchange 2003 server to a Dovecot 1.1.11 server. The problem is that users' mailboxes are huge, several gigabytes with tens of thousands of messages. First Imapsync connects to Exchange and then to Dovecot, and then starts to get Inbox info from Exchange. By the time it gets this info, the connection to Dovecot has timed out. I realize the RFC calls for a 30 minute time out which I believe is hard coded into Dovecot. If there is a way around this by making a configuration change, please tell me. I have posted the same message on the Imapsync list in an attempt to find a work around with patched Imapsync. Thanks in advance. Craig Jackson

[Dovecot] dbox verses maildir - advantages/disadvantages
by James Brown 29 May '09

29 May '09

I am migrating our mail server from Courier-IMAP to Dovecot. We currently use maildir storage format. What are the advantages and disadvantages of Dovecot's dbox format over maildir? Does anyone have any performance benchmarks for both? What do people use to test performance? We are running on a Mac OS X box (10.5.7) using Postfix 2.6. Thanks, James.

[Dovecot] Dovecot and Phpgroupware compatibility
by Carlos Xavier 29 May '09

29 May '09

Hi, recently moved our server from mbox format to Maildir format. Almost all the users are very happy with this, since the speed had increased very much. I used mb2md to do the conversion and on this task all the mailboxes that had "." (dot) on their names were converted to "_". But there is one issue with this, we also use the webmail that comes with Phpgroupware, and it uses some mailbox that have fixed named like INBOX.Sent, INBOX.Draft and so on. When their names were changed the sent messages didn't get saved anymore, so I had to move them back to the old names. After that the sent messages returned to be saved again, but another troube showed up. As they start with .INBOX and have "." on the names, Dovecot shown them as a subdirectory of the INBOX and we got some people upset with this. I need help on configuring Dovecot to not show them this way, because if you look the .INBOX.Sent either on the webmail or by outlook, the field displayed is the sender, witch is not desired. When I did the conversion, to keep the compatibility with the old server (quota, avoid I/O botleneck, etc), I set two Maildirs, one at /var/spool/mail/$USER, to be the INBOX and another at the user home. We are using Dovecot version 1.1.13, and below is the relevant configuration on use. namespace public { prefix = "#mbox/" separator = / inbox = yes list = no location= maildir:/var/spool/mail/%u/:CONTROL=~/control:INDEX=~/control } namespace private { separator = / prefix = location= maildir:~/Maildir/:CONTROL=~/control:INDEX=~/control inbox = no } Best Regards, Carlos Xavier.

[Dovecot] Does a plugin can have root privileges ?
by Fabien 29 May '09

29 May '09

Hello, I wish to get "Fetchmail Wake" works in my environment. This plugin send SIGUSR1 to fetchmail so it wakes up when mail client grabs mail. For the moment "Fetchmail Wake" is executed by mail_uid (defined in dovecot.conf) which is not enough to send signal to fetchmail daemon (and access to fetchmail.pidfile). Thank you!

[Dovecot] Inotify instance limit for user exceeded, disabling?
by dovecot＠corwyn.net 29 May '09

29 May '09

I'm seeing this message in my /var/log/maillog: May 26 12:35:00 agencymail dovecot: IMAP(info(a)example.com): Inotify instance limit for user exceeded, disabling. Increase /proc/sys/fs/inotify/max_user_instances I rummaged through google, and found : http://www.dovecot.org/list/dovecot-cvs/2008-May/011132.html which says I need to increase /proc/sys/fs/inotify/max_user_instances (no surprise given the error message really). I can fix that with echo 256 > /proc/sys/fs/inotify/max_user_instances , but as /proc is temporary, so if I change it won't it break if/when the system reboots? The error message also implies that something has been disabled. If I increase /proc/sys/fs/inotify/max_user_instances will it fix automatically, or do I need to do something else? since it's a kernel message, I suspect just restarting dovecot won't do it. And what exactly is breaking when I receive this notification? The proc docs indicate: /proc/sys/fs/inotify (since Linux 2.6.13) This directory contains files max_queued_events, max_user_instances, and max_user_watches, that can be used to limit the amount of kernel memory consumed by the inotify interface. For further details, see <http://linux.die.net/man/7/inotify>inotify(7).

[Dovecot] A few easy pam and virtual domains questions
by Mauricio Tavares 29 May '09

29 May '09

I am using dovecot with postfix, which was setup to do virtual domains. Dovecot is setup to authenticate against pam (I know, I know) and knows to look for email in /var/spool/vmail/: virtual_mailbox_base = /var/spool/vmail I also have virtual_mailbox_maps defined as virtual_mailbox_maps = hash:/etc/postfix/vmaps.txt where I currently only have one account, % cat /etc/postfix/vmaps.txt raub(a)domain.com domain.com/raub/ % Inside raub we have the usual 3 directories, new,cur, and tmp. When I try to login through imap as raub@domain.com@mail.domain.com (i.e. since we are doing the virtual domain thingie, the username has to indicate the domain it belongs to), it will not take it. But, if I login as raub(a)mail.domain.com, it has no problems authenticating. However, it now expects to retrieve email from /var/spool/vmail/raub instead of /var/spool/vmail/domain.com/raub. Why would it be doing that? Could it be that pam reports raub to be a local account and as a result simply ignoring vmaps.txt? I asked dovecot to log everything it could. When I checked the log file, the following line screamed at me: dovecot: May 27 14:40:28 Info: IMAP(raub): maildir++: root=/var/spool/vmail//raub, index=, control=, inbox=/var/spool/vmail//raub Note the "//" in root and inbox declarations; between those slashes I would expect to be domain.com. Compounding the problem, and perhaps a clue of how pam is telling what these accounts are, postfix is completely ignoring /var/spool/vmail, placing the emails in /home/raub/Maildir (account is actually being nfs-automounted and user authenticated through ldap through pam). Once again I am guessing it too is being told raub is a local user; am I correct?

[Dovecot] RFC 3501 section 7
by Scott Haneda 27 May '09

27 May '09

Hello, been lurking a while, about to move over to Dovecot soon. I have a nice test machine up and running. My previous email server when talking IMAP to Apple Mail, will eventually go "deaf" and new messages will not make it to the Inbox of Apple Mail Client. A restart of the desktop application is required. I am told that the reason for this is that my current email server adheres to RFC 3501, specifically section 7, the second paragraph of which says: The client MUST be prepared to accept any response at all times. Apparently, Apple Mail is not adhering to that, and my email server is sending out that type of response. However, I look at this list, for which I am not entirely sure how accurate the actual test is: http://www.imapwiki.org/ImapTest/ServerStatus It lists Dovecot as one of only two that are fully compliant IMAP servers. Congrats on that. My questions are: Does Dovecot in fact support correctly the above mentioned RFC and subsection? I assume so. That being the case, I have not had issues in my testing of Dovecot, nor heard reports of Apple Mail and IMAP having any significant problems. How, if that is the case, can Apple Mail and Dovecot work well with each other, and my current email server is not able to? My primary reason for moving to Dovecot is to not be burdened by this issue, as well as have what I consider to be a more advanced storage mechanism for the actual messages. What I would like to avoid, is spending a lot of time migrating thousands of users to a new system, to only have them burdened by the same inability to have email come to them without an application relaunch. Thank you for any insight on this. * I have filed a bug report with Apple, which was accepted. Their system does not allow me to see the status on the report once it has been closed. -- Scott * If you contact me off list replace talklists@ with scott@ *

Hi all Trying to setup dovecot with mysql and postfix, I have configured it as given below. thecot user has the dovecot group as primary, and is also a member of mail and dovecot-users. Still, it can't setgid to dovecot-users. I tried changing the shell for the dovecot user to something useful and chmod'ing a file to dovecot-users, and it work well. Still, no mail comes through and dovecot gives me this error deliver(roy(a)somedomain.com): 2009-05-23 15:02:52 Fatal: setgid(115) failed with euid=115, gid=114, egid=114: Operation not permitted Any ideas? roy # Dovecot config # 1.0.15: /etc/dovecot/dovecot.conf log_path: /var/log/dovecot/dovecot.log log_timestamp: %Y-%m-%d %H:%M:%S disable_plaintext_auth: no verbose_ssl: yes login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login verbose_proctitle: yes mail_privileged_group: mail mail_location: maildir:/var/spool/dovecot/%d/%n auth default: default_realm: eventchief.com verbose: yes debug: yes passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: sql args: /etc/dovecot/dovecot-sql.conf socket: type: listen master: path: /var/run/dovecot/auth-master mode: 432 user: dovecot group: mail -- Roy Sigurd Karlsbakk (+47) 97542685 / 98013356 roy(a)karlsbakk.net http://blogg.karlsbakk.net/ -- I all pedagogikk er det essensielt at pensum presenteres intelligibelt.

[Dovecot] Secure Sockets Layer client certificate authentication
by Stephen Feyrer 26 May '09

26 May '09

Hi everyone. Please note, I've asked a very similar question before and I apologize for sounding like a broken record. Well here it goes. What I want to do is authenticate my users using a certificate. Thereby authenticating both the user and server with strong tokens that are centrally managed. In the worst case scenario the user should only need to enter a password for the certificate store and then the certificate should trigger the appropriate level of access to their account. Is Dovecot the correct tool for the job? If yes then, how? Else if not, then what would you recommend? I have tried setting the auth mechanism to anonymous without any joy. My password file is set with nopassword. All my certificates work well with the Secure Sockets Layer system. This is the configuration I am currently running: # 1.2.beta1: /opt/etc/dovecot/dovecot.conf # OS: Linux 2.6.12.6-arm1 armv5tejl log_path: /opt/var/log/dovecot.log info_log_path: /opt/var/log/dovecot-info.log protocols: imaps ssl_ca_file: /opt/etc/ssl.ca/cacrl.pem ssl_cert_file: /opt/etc/ssl.ca/newcerts/imap.cer ssl_key_file: /opt/etc/ssl.ca/private/imap.key ssl_parameters_regenerate: 24 ssl_cipher_list: ALL:!LOW:!SSLv2 ssl_verify_client_cert: yes disable_plaintext_auth: yes verbose_ssl: yes login_dir: /opt/var/run/dovecot/login login_executable: /opt/libexec/dovecot/imap-login login_user: guest login_processes_count: 2 login_max_processes_count: 4 mbox_write_locks: fcntl mail_process_size: 512 imap_client_workarounds: outlook-idle tb-negative-fetch auth default: user: admin verbose: yes debug: yes ssl_require_client_cert: yes ssl_username_from_cert: yes passdb: driver: passwd-file args: /opt/etc/dovecot/h.org/passwd userdb: driver: passwd This is a log of a login attempt: dovecot: May 25 11:55:58 Info: auth(default): new auth connection: pid=22556 dovecot: May 25 11:56:08 Info: imap-login: Valid certificate: /O=home.org/emailAddress=admin(a)nas2.h.org/L=W/ST=C/C=G/CN=h.org dovecot: May 25 11:56:08 Info: imap-login: Valid certificate: /C=G/ST=C/O=h.org/OU=K F/CN=k dovecot: May 25 11:56:10 Info: auth(default): new auth connection: pid=22585 dovecot: May 25 11:56:16 Info: auth(default): client in: AUTH 1 PLAIN service=imap secured valid-client-cert cert_username=k lip=10.1.1.245 rip=10.1.1.1 lport=993 rport=53430 dovecot: May 25 11:56:16 Info: auth(default): client out: CONT 1 dovecot: May 25 11:56:16 Info: auth(default): client in: CONT<hidden> dovecot: May 25 11:56:16 Info: auth(default): passwd-file(k,10.1.1.1): lookup: user=k file=/opt/etc/dovecot/h.org/passwd dovecot: May 25 11:56:16 Info: auth(default): passwd-file(k,10.1.1.1): No password dovecot: May 25 11:56:16 Info: auth(default): client out: OK 1 user=k dovecot: May 25 11:56:16 Info: auth(default): master in: REQUEST 6 22164 1 dovecot: May 25 11:56:16 Info: auth(default): passwd(k,10.1.1.1): lookup dovecot: May 25 11:56:16 Info: auth(default): master out: USER 6 k system_user=k uid=500 gid=100 home=/ dovecot: May 25 11:56:16 Info: imap-login: Login: user=<k>, method=PLAIN, rip=10.1.1.1, lip=10.1.1.245, TLS With this configuration the client will connect over ssl and identify itself with a certificate but a client password is still required. -- Regards Stephen.

[Dovecot] libsieve problems / wishes
by Steffen Kaiser 26 May '09

26 May '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, I'm trying libsieve (853:42e154b8792e) to cope with our current installation, the following issues arise: 1) vacation addresses are compared case-sensitivly, e.g.: vacation :addresses [ "Steffen.Kaiser(a)example.com" ] ""; it won't match "steffen.kaiser@...". attached patch makes a first shot about that problem, leaving: 1a) maybe one should lower-case :addresses argument at compile time and my_address at run-time and then use strcmp() again. 1b) duplicate checks are case-sensitive, too. This is probably no big issue, because if the same person uses different variants of his/her mail address for sending, s/he does not deserve better. 1c) Suppression of replies to own mails are case-sensitive, too. Well, many people I know test that "it just works" by sending themselves a mail. I would disable this check. 2) we have about 157 ways to write the domain part. Not all accounts are available in all of them, but it's close to it. The old vacation program we used prior to "cmusieve" didn't care about the domain unless explicitly given. It was quite painful. Attached patch adds a "domainless" variant of :addresses arguments in such way, that vacation :addresses [ "Steffen.Kaiser" ] ""; matches any domain. Ideally, it would be better to specify all valid domains, but perhaps one can leave that for another approach with a different syntax, e.g. with "@*" as domain? Maybe, there is a better approach. Now there is possibility that common local parts are matched from alien domains easily. If to specify a set of "default" domains would be an option for libsieve, what is the suggested way: - - as user-option via dovecot.conf? - - as admin-enforced Sieve-script that sets some internal variables? aka using the multi-script capability - - ??? 3) Because I try to migrate from cmusieve v1.0, I have a name issue with "imapflags". README sec "* Supports all extensions provided by the original CMUSieve plugin:" and sec "Implementation Status" explains that "imapflags" is available. This is not true entirly: "imapflags" is not, lib-sieve uses the name "imap4flags" as defined by RFC. So, it leaves me with two options: 3a) convert all user scripts and hack Horde-Ingo, or 3b) have libsieve accept the alias "imapflags" for the extension "imap4flags". Would it be worhtwhile for libsieve to implement aliases for extensions, so that they are available in require by more than one name? About Horde-Ingo, maybe they have an update to use "imap4flags", too, but it looks like that I upgrade Dovecot before Horde.

[Dovecot] Maildir with LAYOUT=fs not working
by Rich Wales 26 May '09

26 May '09

I'm considering converting a Cyrus system (managing my family's e-mail) to Dovecot. I'm trying Dovecot 1.1.15 on an Ubuntu 9.04 (2.6.28-11-server) system. My production server is currently running Cyrus 2.3.14. Since I have a huge number of folders and subfolders, I need to use LAYOUT=fs. However, it's not working consistently. I tried setting up a test account in Thunderbird (2.0.0.21), and I was able to create folders under the Inbox, and they showed up as nested subdirectories under my ~/Maildir on my mail server. So far, so good. However, when I tried a home-grown Perl script (an archival scheme for my work e-mail), Dovecot wouldn't create subfolders properly; instead of nesting them (as I thought LAYOUT=fs would do), it used a flat layout. Here is a trace (generated by my Perl script) of an IMAP session. This was supposed to log in as the user "stanford" (the name of my archival account); create a folder named "2009" if not already present; create (again, if not already there) a "2009-05" folder inside the "2009" folder; and, finally, save a message (marked as seen) inside the "2009-05" folder. 1 LOGIN XXXXXXXX XXXXXXXX1 OK Logged in. 2 STATUS user.stanford.2009 (MESSAGES)* STATUS "user.stanford.2009" (MESSAGES 0) 2 OK Status completed. 3 STATUS user.stanford.2009.2009-05 (MESSAGES)* STATUS "user.stanford.2009.2009-05" (MESSAGES 3) 3 OK Status completed. 4 APPEND user.stanford.2009.2009-05 (\Seen) {4043} + OK (message text here . . .) 4 OK [APPENDUID 1243306507 4] Append completed. 5 LOGOUT* BYE Logging out The above works perfectly when I'm talking to my Cyrus server. However, when I tried the same thing with Dovecot, I got a folder named "user.stanford.2009" in the "stanford" account's Maildir, and then another folder named "user.stanford.2009.2009-05" (again, in the Maildir -- NOT nested in the "user.stanford.2009" folder) -- and the message was stored in the "user.stanford.2009.2009-05" folder. I tried changing my Perl script to use "INBOX" instead of "user.stanford" -- but the result was basically the same, except I got new folders named "INBOX.2009" and "INBOX.2009.2009-05" directly in my archival account's Maildir. Finally, I tried omitting any prefix at all on the folder names, and I got new folders named "2009" and "2009.2009-05" -- again, directly in Maildir -- no nesting of one folder within another. I suppose I actually have two issues here -- the lack of folder nesting (even with LAYOUT=fs), and also Dovecot's failure to recognize a "user.XXX." prefix on a mailbox name as designating user XXX's inbox (something that seems to work fine on Cyrus). My Cyrus server currently has over 1,600 folders and subfolders, so I absolutely can't / won't consider switching it to Dovecot unless I can get the nested filesystem layout working. Any thoughts? -- Rich Wales / richw(a)richw.org / richw(a)stanford.edu Wikipedia: http://en.wikipedia.org/wiki/User:Richwales Facebook: http://www.new.facebook.com/profile.php?id=206680

[Dovecot] Converting mbox files with dots in names to Maildir
by Kenneth Porter 26 May '09

26 May '09

I tried to run convert-tool from dovecot-1.2-0.rc2 on a tree of mbox files with some containing dots in the filenames and got this failure: # /usr/libexec/dovecot/convert-tool ken /home/ken mbox:/home/ken/mail maildir:/home/ken/Maildir Error: Mailbox conversion: Couldn't create mailbox Lists.WINE.patches: Mailbox already exists Error: Internal failure *** glibc detected *** /usr/libexec/dovecot/convert-tool: double free or corruption (fasttop): 0x08ce6cc8 *** The directory in question contains these files: # ls Lists/WINE/ announce bugs cvs devel patches patches.20050130 Will I need to go through the (large) file tree and rename all files with dots in the names? If so, anyone have a script that will do that? (Changing the dot to dash would be fine with me.)

[Dovecot] lda deliver per instance sieve configuration
by J.P. Trosclair 26 May '09

26 May '09

I'd like to override the sieve settings in dovecot.conf for a deliver instance that is being run from a custom archiving script. This is dovecot 1.0.15 on debian lenny. Is this possible? Doesn't appear to be looking through the WIKI. If it's not any suggestions? The problem is the user specific sieve scripts override where the archived mail is supposed to be stored (maildir:~/.Archives.YYYY-MM) so I'd like to disable their sieve scripts while the archived mail delivery via deliver is taking place. Thanks, J.P.

[Dovecot] Separate home and mail folders problem on delivery
by Николай Бочев 26 May '09

26 May '09

Hello, I am using dovecot 1.2rc series on my mail server combined with postfix ( virtual users with postgre ). I have setup separate home and mail locations. It works fine ( with sieve etc. ). The user home folders are in /home/vmail/%d/%n and mailboxes are in /srv/mail/%d/%n . The permissions are fine and everything is working except in the following case : If a user does not have a home dir already crated ( the home dirs get auto created when creating a sieve script through managesieve for example ), and he recieves a message with an attachment, the delivery fails with the following error : May 19 10:47:28 mail postfix/pipe[2759]: 969531007B: to=<office(a)grandstarco.com>, relay=dovecot, delay=2296, delays=2296/0.2/0/0.06, dsn=4.3.0, status=deferred (temporary failure) The Dovecot deliver log says : > 2009-05-19 10:47:28 deliver(office(a)grandstarco.com): Error: creat(/home/vmail/grandstarco.com/office/.temp.mail.dodo.bg.2760.1242719248… failed: No such file or directory > 2009-05-19 10:47:28 deliver(office(a)grandstarco.com): Error: copy: i_stream_read() failed: No such file or directory > 2009-05-19 10:47:28 deliver(office(a)grandstarco.com): Error: sieve: msgid=<1242716935.24056.6.camel(a)shiny.bgservice.local>: failed to store into mailbox 'INBOX': Internal error occurred.
