[Dovecot] Antispam plugin + scriptsieve
by Allan Cassaro 03 Dec '08

03 Dec '08

Hi, I wrote a little python program that works with antispam plugin, to create or remove sieve rules based on "From:" of any e-mail that is moved to some folder configured in dovecot.conf. He works fine with "Felamimail" the email program of "eGroupware". After setup, is very simple: If an user move a message to "blocked" folder, is appended a rule in the script sieve of this user. If the message is deleted or moved out that folder, the rule is removed too. The setup is very simple: (after setup antispam plugin) Change this in dovecot.conf: protocol imap { mail_plugins = antispam } plugin { antispam_spam = Blocked antispam_mail_sendmail = /usr/libexec/dovecot/blockthis.py antispam_mail_sendmail_args = -u;%u antispam_mail_spam = -a antispam_mail_notspam = -d } Hooo... this script create a "include global script" statament in script sieve... If you don't want this feature, just comment this 2 lines: sievelist.append('require ["fileinto", "include"];\n') sievelist.append('include :global "global.sieve";\n') Here this is very useful! :D This script was created to suit my needs, so, have some paths in the code... It's not very "user friendly" yet... but if have intereting I will implement others features (like a config file). Download here: http://allan.cassaro.googlepages.com/blockthis.py Regards.

[Dovecot] my_vsnprintf crash on HP-UX

Hi, sorry for the double post, I stupidly composed this as a reply to an earlier mail, which causes it to appear in an older thread.

[Dovecot] Loginname - mapping
by Roald Amundsen 03 Dec '08

03 Dec '08

Hi! I have a server with a few thousand mailboxes (for a few hundred domains) on it. The usernames are following several naming conventions: username_domain domain_username username_domain.tld username-domain domain.username The reason for this chaos is that the accounts were set up on different mailservers, some imail, some linux, some with virtualmin and some manually and through aquisitons etc it has all ended up in one server. Now we are setting up atmail to replace imp. The loginprocess of atmail is a bit different in that you just type in your mail address and atmail tries a few combinations of loginnames to login. However, some of the combinations over atmail cant login to. Some of them works fine when using this line in dovecot.conf auth_username_translation = @_ Is there any facility to let dovecot do username mapping? If I eg have a file: usermapping that looks like this: user(a)domain1.com domain1_user user(a)domain2.com user_domain2 user(a)domain3.com domain3.user And yes, I know that the best way is to start again and use virtual domains and get all into one naming standard, but unfortunately, that is not going to happen. The other alternative is of course to hack into the source code of atmail, but I am not that confident in PHP. Any ideas? -- Regards Roald Amundsen

[Dovecot] Problem with sieve: Keep: Generic Error
by Thomas Siebert 03 Dec '08

03 Dec '08

Hi, i came across a strange error message in Ubuntu 8.10s package (Dovecot 1.1.4) regarding sieve: sieve runtime error: Keep: Generic Error sieve_execute_bytecode(/etc/dovecot/sieve/default.sievec) failed Note that the Sieve Scripts are basically executed fine and working fine. After a lot of testing I suppose the following: "keep" doesn't detect the private namespace I have to use (courier-compatibility...), thus sieve fails to do "keep", the message is handed back to dovecot-deliver which does a "keep"-similar action itself. If I have a script with "keep;" as the only command, I get this error message. If my script is totally blank (i.e. implicit keep only), I get the same error. But if there's no implicit or explicit "keep", e.g. "fileinto INBOX;" as only command, there's no error. Also IMAP-Folders, e.g. "fileinto INBOX.Test", work. Unfortunately, "fileinto INBOX" as default is no option for me, as I use a delimiter and want to let deliver put the mails into the according IMAP-Folders. Is this a known bug? Any Ideas?

[Dovecot] Compilation of 1.1.6 fails on HP-UX 11.31
by Marc Beyer 03 Dec '08

03 Dec '08

Hi, $ uname -srv HP-UX B.11.31 U $ cc --version cc: HP C/aC++ B3910B A.06.20 [May 13 2008] Compilation fails, output of configure and make are given below. The cause of this is almost certainly that this version of HP-UX does define the QCMD macro in sys/quota.h (checked in the ifdef line 26 dovecot-1.1.6/src/plugins/quota/quota-fs.h) as well as the dqblk struct, but the latter with different fields than the Linux version. Older versions of HP-UX seem not to have contained this macro(? can't check this at the moment), which is probably why it was used to distinguish between HP-UX and Linux in quota-fs.h. Deleting lines 26-28 and 30 from dovecot-1.1.6/src/plugins/quota/quota-fs.h fixes the problem for HP-UX, but of course a real fix would need to add a more current method of distinguishing between Linux and HP-UX. If there's any more helfpul information you'd like let me know, cheers, Marc configure: ...

[Dovecot] Using namespaces to duplicate mailboxes (Doable?)
by Julio C. Ortega 03 Dec '08

03 Dec '08

Greetings. As part of a new installation of dovecot, we are exploring backup options, and wondered if it's at all possible to define a couple of namespaces where messages get duplicated to be saved in another disk for fast recovery. (we do not intent to load balance between the two, all we would like is to see if it's possible to have duplicate mailboxes so to keep a fast working backup _besides_ normal methods: tape, external disk, etc.) The whole idea behind this would be that in case of a major failure of the array holding the mailboxes, a fast working backup can be put in place. Other thing we would like to know (and i reckon it's a long shot) if it's possible to "hide" this mailbox copy from the IMAP clients, so as to prevent any user from subscribing _again_ to the same folders. Naturally this last thing is to be considered only if the former (mailbox copy trough namespaces or other dovecot _internal_ method) it's at all possible. Any feedback or better ideas are totally welcome. -- --------------------------------- Julio C. Ortega Grupo de Infraestructura ONUVA | Integración de Sistemas http://www.onuva.com

[Dovecot] data retention and e-discovery rules
by Trever L. Adams 02 Dec '08

02 Dec '08

Hello All, I am in the United States where we have e-discovery rules. Some organizations have to retain data for a certain amount of time, others are required to have a data retention policy. This means that while it should probably be possible for a user to "delete" an email so they do not see it. The server needs to store it, possibly in a tree that mirrors the folder setup of the user (so if it is in "Sales" folder, it should move to namespace "hidden", or similar, in folder "Sales"). Is there anything like this in dovecot? Is it possible to use cron jobs to see when the message was deleted (Maildir) and erase it based on policy? (Python scripts are fine if the users password isn't needed.) Thank you, Trever Adams

[Dovecot] symlink() failure in 1.2 managesieve

I've been simultaneously learning about dovecot and experimenting with the 1.2.alpha4. To start I built an rpm under CentOS 5.2 from: dovecot-1.2.alpha4.tar.gz dovecot-1.2-managesieve-0.11.2.tar.gz dovecot-1.2.alpha4-managesieve-0.11.2.diff.gz dovecot-1.2.alpha4.tar.gz dovecot-1.2-sieve-0.1.2.tar.gz and then setup with mysql to use virtual users. Mail-wise, it all works. :) Where I'm having trouble is with the managesieve part. I find that when I activate a sieve script I get a symlink() failure message in /var/log/maillog similar to this: Dec 2 05:12:47 hostname dovecot: MANAGESIEVE(account(a)hostname.com): sieve-storage: Creating symlink() hostname.com/account//.dovecot.sieve to /usr/local/virtual/hostname.com/account/sieve/Test.sieve failed: No such file or directory I began to chase this first by inserting i_info() calls into various points of the managesieve build and later by attaching to the process with gdb. I can see that in sieve_storage_script_activate() the storage->active_path member is incomplete (i.e., is not a full, absolute path name) and the cwd is "/tmp", thus the symlink() call fails. Based on what I've been reading in the documentation, shouldn't the system have resolved the "home" area for the mail to be the same as what is determined for the virtual user mail area? Using the README in the alpha4 package I've found that I can get it to work by adding the following after the "protocol manageseive {}" section: plugin { sieve=/usr/local/virtual/%d/%n/.dovecot.sieve sieve_storage=/usr/local/virtual/%d/%n/sieve } While that helps, I'm a little confused as to why I need to do this. I believe that the documentation states that the sieve defaults to .dovecot.sieve under the MAIL_LOCATION directory. So it is not clear to me if I am doing something wrong, if there is an oversight in the software and/or documentation (or perhaps my reading of it), or is it really necessary to specify the same information multiple times? - Bruce Here is some output that may be of use: -bash-3.2# dovecot -n # 1.2.alpha4: /etc/dovecot.conf # OS: Linux 2.6.18-8.1.8.el5xen x86_64 CentOS release 5.2 (Final) ext3 info_log_path: /var/log/dovecot.log protocols: imap imaps pop3 pop3s managesieve 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 login_executable(managesieve): /usr/libexec/dovecot/managesieve-login max_mail_processes: 100 first_valid_uid: 150 last_valid_uid: 150 mail_location: maildir:/usr/local/virtual/%d/%n mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_executable(managesieve): /usr/libexec/dovecot/managesieve mail_plugin_dir(default): /usr/lib64/dovecot/imap mail_plugin_dir(imap): /usr/lib64/dovecot/imap mail_plugin_dir(pop3): /usr/lib64/dovecot/pop3 mail_plugin_dir(managesieve): /usr/lib64/dovecot/managesieve auth default: mechanisms: plain digest-md5 debug: yes debug_passwords: yes passdb: driver: sql args: /etc/dovecot/dovecot-mysql.conf userdb: driver: sql args: /etc/dovecot/dovecot-mysql.conf plugin: sieve: /usr/local/virtual/%d/%n/.dovecot.sieve sieve_storage: /usr/local/virtual/%d/%n/sieve ----- -bash-3.2# grep -v '^ *$#.*$\?$' /etc/dovecot/dovecot-mysql.conf driver = mysql connect = host=/var/lib/mysql/mysql.sock dbname=postfix user=postfix password=postfix default_pass_scheme = MD5-CRYPT user_query = \ SELECT maildir as home, 150 AS uid, 12 AS gid FROM mailbox WHERE username = '%u' password_query = select password from mailbox where username='%u'

I did some bugreports in last time and also compiled dovecot with some changes in guidance from timo to let the bug be more understandable but so far nothing helped. i like dovecot but if these bugs not get solved i cannot upgrade my maschines to > 1.0.15 :( Thanks, Andre

[Dovecot] Feature request: Force leave copy on server
by Bárður Háskor 02 Dec '08

02 Dec '08

It would be very nice, if I could force users to leave a copy on the server when using POP3. This is because users primarily use a web interface to access mail (the web interface uses IMAP), but users can also download messages using POP3. Users who forget to set the "Leave copy on server" get all their messages deleted in the web interface, and mostly they don't want (expect) this behavior. Isn't it possible to create another way to tag POP3 messages as deleted without these being deleted in IMAP? Sincerely, Bardur Haskor

[Dovecot] help on MailLocation please!
by Li Wei Nan 01 Dec '08

01 Dec '08

Hi Everyone, I'm now using dovecot with a POP3&SMTP server called JAMES. I want dovecot and james to share the email location. Both dovecot and james can store email in mbox format. However, the james will only store mbox mail repo in a fixed dir, such as: /var/mail/ And it will naming each user's mbox repo by its name, such as /var/ mail/tom or /var/mail/peter, etc. So I have to config dovecot for it to fit the situation. So I config dovecot as: mail_location = mbox:/var/mail:INBOX=/var/mail/%u The inbox get worked now, dovecot can read the mbox file created by james correctly. However, dovecot make each user's Trash, Sent in same directory: /var/mail. So it means all the user just have one Trash, Sent. I've read the Wiki carefully and tried some different config and still cannot get it work. Can anyone gives me some advice on it? Thanks a lot! What I hope to achieve is: - Let dovecot read everyone's inbox at: /var/mail/%u (it's a mbox file, not dir) - Let dovecot store everyone's Trash, Sent in /var/mail/%u/mail Thanks in advance. - Li Wei Nan

[Dovecot] Dovecot POP3 problem: Authentication suddenly fails until dovecot gets restarted
by Carsten Buchenau 01 Dec '08

Hi, I am running dovecot with postfix and OTRS2 on a fresh Ubuntu 8.10 Server system. OTRS2 is configured to poll new email to otrs-incoming@localhost via POP3 every 5 minutes. It works, but after approximately 20 hours it suddenly stops working and only a restart of dovecot helps. The outage starts at different times during night (00:15 on Thursday, 1:15 on Friday, 3:20 on Saturday). I checked all cron-jobs, but couldn't find anything matching. Anyone any idea?

[Dovecot] Relay-Ctrl, error message
by Wouter van der Schagt 30 Nov '08

30 Nov '08

Hi all, I'm trying to get Relay-Ctrl to work (as explained on http://wiki.dovecot.org/HowTo/PopBSMTPAndDovecot) however when i add: mail_executable: /usr/local/bin/envdir /etc/relay-ctrl /usr/local/bin/relay-ctrl-chdir /usr/local/bin/dovecot-settcpremoteip /usr/local/bin/relay-ctrl-allow /usr/local/libexec/dovecot/imap to /usr/local/etc/dovecot.conf I get the following error message when doing dovecot -n Error: Error in configuration file /usr/local/etc/dovecot.conf line 126: Expecting '=' Fatal: Invalid configuration in /usr/local/etc/dovecot.conf So I'm guessing i misplaced the line somewhere in the config file. Where should it be placed? Does it work for both pop3 and imap? Sincerely, - Wouter van der Schagt

[Dovecot] Cache details
by Warren Baker 30 Nov '08

30 Nov '08

Hi All, Is there any specific details we can extract from dovecots authentication cache (besides Authentication cache hits)? Reason i am asking is because we had a mysql user account which was returning a unknown user account. Fixing the one value in the sql result didnt have any affect and Dovecot was still returning an auth failure for the user after 24 hours had elapsed, even though auth_cache_negative_ttl was set to 120. Restarting Dovecot or a SIGHUP on dovecot-auth sorted out the problem. It would be useful if we could interrogate the cache somehow to see what cache entry is been hit. Auth cache settings are as follows: auth_cache_size = 51200 auth_cache_ttl = 2100 auth_cache_negative_ttl = 120 Any suggestions appreciated. Thanks, Warren

[Dovecot] INTERNALDATE call, timezone randomly changes
by Guy 30 Nov '08

30 Nov '08

Hi guys, I've run into an odd little problem. We use SquirrelMail as the basis for our webmail. Recently I've had a user complaining that the "Received" time on mail in the Sent folder has changed between logins. The change is always been by +1 hours or -5 hours. While checking, our developer had a time changed by +2 hours. On refresh it changed back. He poked through the code and it looks like SquirrelMail gets the received date via an IMAP command: A003 FETCH 1:10 (INTERNALDATE FLAGS BODY.PEEK[HEADER.FIELDS (To Content-Type Subject Date)]) I'm running dovecot 1.1.6, and I'm wondering how that function gets the date and time? If I can isolate the source of the timezone I can try and correct it. The server time shown by "date" is correct and /etc/localtime is /usr/share/zoneinfo/Europe/London (which is correct - I've also se the timezone in /etc/conf.d/clock is set to "Europe/London" now), so I'm wondering where else the information could be coming from? Thanks for any information you can give me to help isolate the problem. Guy -- Don't just do something...sit there!

[Dovecot] v1.2.alpha4 released
by Timo Sirainen 30 Nov '08

30 Nov '08

http://dovecot.org/releases/1.2/alpha/dovecot-1.2.alpha4.tar.gz http://dovecot.org/releases/1.2/alpha/dovecot-1.2.alpha4.tar.gz.sig Note that there are significant changes in this release from alpha3 and I haven't tested everything extensively. Be careful. The next release will hopefully be v1.2.beta1 with a feature freeze. Most importantly shared mailboxes and IMAP ACLs are finally supported. This is mainly thanks to the Kolab people (looks like I forgot your names from NEWS file, the next release will have them). I'll have to write a wiki page about ACLs, but the main thing you need to know is that if you want shared mailboxes to be LISTable by other users, you'll need to specify acl_dict. If you don't expect many shared mailboxes, a file backend is the easiest, but you could also use SQL or Berkeley DB. With a file backend you could also create per-domain files, which will improve performance if you don't need cross-domain shared mailboxes. You could do this with e.g.: acl_file = /home/virtual/%d/shared-mailboxes Also full text searching works now better with virtual mailboxes. Previously the fts would have duplicated the indexes for virtual mailboxes. Now with Solr backend it searches the original mailboxes directly. Although this is still missing some optimizations and also it doesn't check first if mails are missing from the original mailboxes, so it may not find everything. Also this still doesn't work with Squat backend.. Anyway, a bit more code and Dovecot will have fast full text searching from all mailboxes (virtual * mailbox). I implemented also draft-gulbrandsen-imap-response-codes-04, which adds some [codes] for all IMAP command failures, which should make it possible for clients to figure out more easily what caused the failure. Hopefully the draft won't change much anymore. :)

Hello, Thank you for this link, but this is not what I want. Dovecot is only used for imap. Currently, authentication works fine, but new fields are created in a subdirectory. Example: /var/vpopmail/domains/0/domain.com Once authenticated, I just want to be in chroot /var/vpopmail/domains/0/domain.com/user and not in /var/vpopmail/domains/domain.com/user I explained that vpopmail which manages the creation of areas and I can not influence the subdirectory.

[Dovecot] ManageSieve and invalid scriptname

I made this today with a couple of "sed + awk" and a wraper for managesieve-login... but, this is definily not the best way to do this... This is possible to do?

[Dovecot] Namespaces and shared folders
by bbell2000 28 Nov '08

28 Nov '08

I had a working dovecot install before I tried to implement shared folders using namespaces. I added the following to /etc/dovecot/dovecot.conf: namespace private { separator = prefix = inbox = yes } namespace public { separator = / prefix = location = maildir:/home/public/shared/Maildir } </pre> I created my shared folder using the maildirmake command that came with qmail: maildirmake -S /home/public/shared/Maildir maildirmake -s write -f online /home/public/shared/Maildir chown -R dovecot:shared /home/public/shared find /home/public/shared -type d -exec chmod 0777 {} \; find /home/public/shared -type f -exec chmod 0666 {} \; At this point, the online folder shows up as a subscribable folder in Thunderbird. I can subscribe to online and I can still access my Inbox. But I can't get to any of the folders in my Inbox (Trash, Drafts, etc.). I can access these folders if I comment out the namespaces and revert to the default behavior. There are no clues in mail.err, mail.info or mail.warn -- the only messages are the ones written when my client establishes a successful IMAP connection.

[Dovecot] UIDL question
by Wouter van der Schagt 28 Nov '08

28 Nov '08

Hi all, I'm migrating a Postfix + Dovecot 1.0 server with mboxes to Qmail + Dovecot 1.4 with Maildirs and encounter the following the problem. Using perfect-maildir.pl from: http://perfectmaildir.home-dn.net/ i can relatively succesfully convert the mbox to a Maildir. The problem, however is that clients with "leave mail on server" set to on retrieve all email a 2nd time. I understand this must be because the email client "sees" a different UIDL and downloads the message again. Looking at the 1.0 configuration, i do not see a "pop3_uidl_format" setting. So was wondering how the UIDL is generated. Is anybody aware of a conversion script that properly maintains the UIDL? Or am I misisng something else here? Sincerely, - Wouter van der Schagt

If I try to invoke the expire-tool like /usr/local/sbin/dovecot --exec-mail ext /usr/local/libexec/dovecot/expire-tool --test I get [root@m ~]# /usr/local/sbin/dovecot --exec-mail ext /usr/local/libexec/dovecot/expire-tool --test Error: read(/var/run/dovecot/dict-server) failed: Remote disconnected Hmm. I searched for hints but could not find a related discussion or problem. Here are the relavant config parts: dict { expire = db:/var/lib/dovecot/expire.db } plugin { # expire plugin expire_dict = proxy::expire expire = backup 7 spam 30 # If you have a non-default path to auth-master, set also: auth_socket_path = /var/run/dovecot/auth-master } Any ideas? Has anybody got this working ? The file /var/lib/dovecot/expire.db doas not exit even though I restarted DC quite a while ago. Regards, Jakob

In my case, the cause was a large spam message (above the configured MaxMessageSize parameter for DSPAM) that was skipped during tests and thus no signature was added. Might this be true in your case? As a general suggestion for Johannes: maybe it is better to ignore this error silently, just move the message and don't call DSPAM? > I checked that the given location for the dspam executable is correct, > that the user executing it (dovecot?) is actually able to execute dspam > and that dspam trusts this user.

I have lines like > X-DSPAM-Signature: 1,49084a24139132188715614 Another guess: if that comma is not a misprint, something is wrong in your setup. Regards Eugene

[Dovecot] Can I import RFC822 messages into Dovecot from file system
by bbell2000 27 Nov '08

27 Nov '08

I'm returning to qmail and dovecot after having suffered a complete failure with a different mail system and I'm now trying to figure out the easiest way to recover our messages from the failed system. The messages are stored as RFC822 in individual files and I can easily identify which message belongs to whom. I have qmail and dovecot configured to use Maildir format. I know I can probably write a script that resends the messages... but in addition to adding another layer of transport headers I really don't want, it's going to be way slow unless I disable my current content filters. I'm new to dovecot and what's got me hung up are the indexes that dovecot maintains in each user's directory. Otherwise, I'd probably try copying the messages into Maildir/cur just to see if it worked. I could sure use some ideas about an efficient, reliable means of getting our old messages back. Thanks. -- View this message in context: http://www.nabble.com/Can-I-import-RFC822-messages-into-Dovecot-from-file-s… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] Antispam plugin + script sieve
by Allan Cassaro 27 Nov '08

27 Nov '08

Hi guys, I will start a little script that receive via antispam plugin an email, extract the "from" and "return-path" and create alter the sieve script of the user that send the e-mail. Well, I don't speak english very well (I speak like Borat!!!), but with some examples is better to understand: 1) Some user move an "undesirable" mail to "Automatic Block" folder 2) The antispam plugin call my script 3) The script parse the e-mail and extract the from and return-path mail 4) A rule is added to ~/.dovecot.sieve to dicard messages that came from that e-mail 5) If the user remove the mail from "Automatic Block" folder, the script remove this rule So, my question is: anyone is working on something similar with this? (I don't want to reinvent the wheel) Regards. -- "Não deixe a faculdade atrapalhar seus estudos." http://allan.cassaro.googlepages.com

[Dovecot] deliver segv on sieve redirect
by Andy Howell 27 Nov '08

27 Nov '08

Hello, I've been trying out the bleeding edge, 1.2.alpha4. I'm having a problem with deliver and dovecot-1.2-sieve-0.1.1. I get a segv on this sieve script: require ["fileinto", "reject", "vacation", "envelope", "regex"]; if header :contains "subject" ["urgent"] { redirect "someone(a)somewhere.net"; fileinto "test"; } Seems its happening on the "redirect". If I put the fileinto before the redirect, the fileinto works. I tried putting extra debug statements in plugins/lda-sieve/lda-sieve-plugin.c right after the sieve_execute in lda_sieve_run, but it never prints anything. I'm guessing thats the right place. Its quite possible there is something amiss in my setup. My logs show: Nov 26 02:51:12 marvin dovecot: deliver(andy(a)x.y.org): sieve: using sieve path: /var/mail/vhosts/x.y.org/andy/.dovecot.sieve Nov 26 02:51:12 marvin dovecot: deliver(andy(a)x.y.org): sieve: opening script /var/mail/vhosts/x.y.org/andy/.dovecot.sieve Nov 26 02:51:12 marvin dovecot: deliver(andy(a)x.y.org): sieve: executing compiled script /var/mail/vhosts/x.y.org/andy/.dovecot.sieve Nov 26 02:51:12 marvin postfix/pipe[17027]: 0CA895CB3A: to=<andy(a)x.y.org>, relay=dovecot, delay=0.41, delays=0.33/0.01/0/0.07, dsn=5.3.0, status=bounced (Command died with signal 11: "/usr/libexec/dovecot/deliver") Thanks, Andy

[Dovecot] Released Sieve v0.1.2 (important bug fixed)
by Stephan Bosch 26 Nov '08

26 Nov '08

Hello Dovecot users, Today, Andy Howell tripped an important bug in the Sieve interpreter that makes it crash when redirect is executed. That is why I quickly release yet another new version to provide a fix for this bug. I really should prevent this from happening again in the future by extending the test suite to test the execution of actions. Changelog v0.1.2: - Fixed important bug in the redirect action (and probably other actions like reject and vacation that only send messages). This was a bug in the handling of context information during the execution of actions. It caused the sieve interpreter to crash with a segfault when redirect was executed. The release is available here: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.2.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.2.tar.gz.sig Refer to the initial release mail for more information: http://www.dovecot.org/list/dovecot-news/2008-October/000087.html Regards, -- Stephan Bosch stephan(a)rename-it.nl IRC: Freenode, #dovecot, S[r]us

Interesting. Somebody else was reporting the same errors, but I'm not seeing them. But I'm still using 1.1.2.

[Dovecot] Unable to use imapflags in sieve
by Guillaume Hilt 25 Nov '08

25 Nov '08

Hello, I'm using dovecot 1.1.6 with libsieve 2.2.5 and I can't use the imapflags extension. Here's the begginning of my .dovecot.sieve file : require ["fileinto"]; #require "imapflags"; #require "reject"; #if header :contains "X-DSPAM-Probability: 0.9" { # addflag "$label3"; #} # On déplace le spam dans le dossier Spam et on s'arrête là if header :contains "X-DSPAM-Result" "Spam" { fileinto "Spam"; # addflag "\\Seen"; stop; } # Si le destinataire est l'user apache, on discarde le mail if address :is "to" "ftp(a)shadowprojects.fr" { discard; } # Listes de diffusion if header :contains "List-Id" "dovecot.dovecot.org" { fileinto "Listes.Dovecot"; stop; } If i enable imapflags (require ["fileinto","imapflags"];) sieve won't work anymore (same with reject by the way). Only enabling it without using it (with addflag) is enough to stop sieve from working. All my emails will be delivered in my inbox despite the rules I use. If I remove imapflags, everything is working fine. And I don't see anything in my logs explaining the problem.

[Dovecot] Released Sieve v0.1.1 and ManageSieve v0.11.2 for Dovecot v1.2.alpha4
by Stephan Bosch 25 Nov '08

25 Nov '08

Hello Dovecot users, Since the first release of the new Sieve implementation, not that many bugs were reported. This is probably due to the fact that it is not tried yet by that many people. In the mean time, I did find and fix some more bugs myself, I adapted to changes in Dovecot, wrote some more documentation and started work on the enotify extension. Both Sieve and ManageSieve were changed to match API changes in Dovecot and therefore older versions will not compile against the new Dovecot release. Likewise, these new Sieve and ManageSieve releases will not compile for older Dovecot versions. Changelog Sieve v0.1.1: * Re-enabled support for compiling against dovecot headers. Much like cmusieve, command line tools like sievec and sieved are not compiled in this case. * Started implementation of enotify extension. Not anywhere near finished though. * Adapted to changes in Dovecot on various occasions, making this release dependent on Dovecot >= v1.2.alpa4. + Improved logging of errors at specific occasions and added debug messages to find script execution problems quicker. + Removed code duplication between command line tools and the test suite. Also restructured the sources of the tools. + Added UTF-8 to UTF-7 folder name conversion for compatibility with IMAP. + Created man pages for the command line tools. These are automatically installed upon 'make install' + Incorporated Valgrind support into the test suite and fixed a few memory leaks in the process. - Fixed compile error surfacing for gcc3.4. Forgot mask argument for the open() system call when the O_CREAT flag is specified. Bug found by Sergey Ivanov. - Fixed bug in the sievec tool. -d output was always written to stdout. - Fixed important bug in the imap4flags extension. When no :flags argument is specified, the previous version would always use the final value of the internal variable to set the flags. This means that modifications to the internal variable also affected the bare fileinto/keep actions executed earlier. This does not comply to the RFC. - Fixed bug in the include extension's import/export commands. Duplicate import/exports caused problems. - Fixed bug in the handling of non-existent scripts. Errors were sometimes ignored. - Dovecot omitted unfolding multi-line headers. This was added to the cmusieve plugin after the code was incorporated into the new implementation. This is now implicitly fixed by concurrent change in Dovecot. Changelog ManageSieve v0.11.2: * Adapted to changes in Dovecot, making this release dependent on Dovecot >= v1.2.alpa4 The following files are released: Sieve: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.1.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.1.tar.gz.sig ManageSieve package: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.2.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.2.tar.gz.s… ManageSieve patch: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.alpha4-managesieve-0.11.2.d… http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.alpha4-managesieve-0.11.2.d… The full story of the new Sieve implementation is available in my previous posting: http://www.dovecot.org/list/dovecot-news/2008-October/000087.html I still need to update the wiki with pointers to the new Sieve implementation. I hope to have some time and motivation to do so in the next few days. Have fun testing the new releases and don't hesitate to notify me when there are problems.

[Dovecot] v1.1.7 released
by Timo Sirainen 25 Nov '08

25 Nov '08

http://dovecot.org/releases/1.1/dovecot-1.1.7.tar.gz http://dovecot.org/releases/1.1/dovecot-1.1.7.tar.gz.sig I should have released this earlier since v1.1.6 had that annoying startup problem, but surprisingly few people complained about it so I kind of forgot about it then. BTW. v1.2 progresses nicely. Now that shared mailboxes are finally fully supported, there aren't any widely used IMAP features missing from Dovecot. v1.2.beta1 shouldn't be in too distant future anymore. * IMAP QUOTA extension now returns "MESSAGE" quota, not "MESSAGES". This makes Dovecot now RFC 2087 compliant. Hopefully this change doesn't break anyone's Dovecot-specific quota checking code.. + Added !include and !include_try directives to config file reader. Note that !include doesn't currently work with deliver. The main point here is that ssl_key_password can be placed to a different file with !include_try that deliver can just ignore. + More error/debug message logging improvements. - v1.1.6 gave "userdb didn't return a home directory" error at startup - Some config file parsers (deliver, passwd-file, acl, trash) ignored the file's last line if it didn't end with LF. - fts: SEARCH SUBJECT didn't search messages that weren't already in fts index. - fts-solr: Don't assert-crash if we couldn't connect to Solr. - IMAP: Mailbox deletion gave an error, but still worked, if mails' control directory wasn't the same as index directory. - Several fixes to rarely used mailbox list layout configurations.

[Dovecot] PLAIN password scheme question
by Dmitri V. Ivanov 24 Nov '08

24 Nov '08

Hi, ppls There is some problem with using passwd-like file and plaintext passwords within it. Let's assume we have users speaking russian. They think and remember their passwords also within russian words (they just not change keyboard layout before entering their passwords). So if the user has password like ":jgf" (meaning "ass" in russian) and passwords are stored into passwd-like file within {PLAIN} scheme what will happen? ===== user:{PLAIN}:jgf:1234:1234:.... ===== Isn't it a reason to implement something like {HEX} and why?

But why do you think there's a bug in Dovecot? Note > that Dovecot never even sees this value. It's the kernel that enforces > it, Dovecot simply reacts to a write() failure. The logs stating the "File too large" errors belong to dovecot's deliver process. While I was searching for a solution, I read that deliver honors mailbox_size_limit setting of postfix, I'm not sure if that is correct or not. Note that the destination mailboxes are smaller than 2GB here, but still gets "File too large" error. The machine is 64-bit, so no fs related kernel limits on file size. I have not dived into postfix and/or dovecot internals, but my guess is , dovecot gets the mailbox size limit and behaves accordingly. If that is the case, the problem can be fixed in dovecot's deliver code. If postfix sets file size limit with ulimit before execing deliver, OR uses a similar process which is out of deliver's control, then there is nothing concerning dovecot. If someone can clarify the issue I would be happy. -- Gokdeniz Karadag

[Dovecot] pam auth fail considered mail.error?
by David Halik 24 Nov '08

24 Nov '08

Hello all, Following the Dovecot wiki and migration help, we recently migrated our core IMAP systems from Courier to Dovecot on Solaris. So far it's been working great, but I have one issue that I'm curious about. Just as the docs mention, we also use "syslog_facility = mail" for logging. Unlike in the past, failed PAM auth attempts are now getting logged as mail.error: Nov 24 08:34:34 xxx.xxx.xxx.xxx dovecot: [ID 107833 mail.error] auth-worker(default): pam(dhalik,xxx.xxx.xxx.xxx): pam_authenticate() failed: Authentication failed Is there a reason for this, or a way to configure this behavior? mail.error is a little harsh for pam auth failures and I would think that the auth channel would be used instead similar to other processes (sshd, courier, etc) I'd like to continue using the mail facility, but if every time there is an auth error Dovecot reports to mail.error, my consoles and legitimate error logs are going to be full of something considered a non-issue by most. Any help is appreciated, thanks. -Dave -- ================================ David Halik System Administrator OIT-CSS Rutgers University dhalik(a)jla.rutgers.edu ================================

24 Nov '08

Hi all. I want to use two servers with dovecot using a common file system with drbd. So I have several questions. If one server write a mail to th file system he will use his name as part of the mail identification. the second server will use his own name. Each server will generate it own mail numbers . When an imap or pop user will consult the mails i shoul be confusion. Am I correct. is there a way of solving this issue?? Thanks
