[Dovecot] Sieve and ManageSieve for Dovecot v2.0 merged into one repository
by Stephan Bosch 13 Jan '10

13 Jan '10

Hi, I've merged the Mercurial repositories for Sieve and ManageSieve for Dovecot v2.0 into one repository: http://hg.rename-it.nl/dovecot-2.0-pigeonhole This simplifies the build process significantly. It also allows tightly integrating the implementation of the script storage with the main Sieve library, enabling the possibility to implement alternate means of script storage, like for instance a SQL or LDAP database. Building ManageSieve is still optional as outlined in the INSTALL file. The old v2.0 repositories will be archived soon. I'm slowly but surely progressing towards a first Pigeonhole release for Dovecot v2.0. Regards, Stephan

[Dovecot] using dovecot deliver
by Per Laine 13 Jan '10

13 Jan '10

Hi all! This is my first posting to the list and I really could use some help in getting postfix using dovecot as virtual_transport. I get an error in dovecot-deliver.log that says "Can't connect to auth server at /var/spool/postfix/private/dovecot: Permission denied" Im using postfix as MTA with two virtual domains and virtual users. This is my dovecot -n output: # 1.1.11: /etc/dovecot/dovecot.conf # OS: Linux 2.6.31-17-generic-pae i686 Ubuntu 9.10 ext4 base_dir: /var/run/dovecot/ log_path: /var/log/dovecot info_log_path: /var/log/dovecot.info log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap pop3 imaps pop3s managesieve ssl_cert_file: /etc/ssl/smtpd.crt ssl_key_file: /etc/ssl/smtpd.key disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login login_executable(managesieve): /usr/lib/dovecot/managesieve-login valid_chroot_dirs: /var/spool/vmail mail_location: maildir:/home/vmail/%d/%n mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_executable(managesieve): /usr/lib/dovecot/managesieve 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 mail_plugin_dir(managesieve): /usr/lib/dovecot/modules/managesieve sieve_storage(default): sieve_storage(imap): sieve_storage(pop3): sieve_storage(managesieve): ~/sieve sieve(default): sieve(imap): sieve(pop3): sieve(managesieve): ~/.dovecot.sieve auth default: mechanisms: plain login verbose: yes passdb: driver: passwd-file args: /etc/dovecot/passwd userdb: driver: passwd-file args: /etc/dovecot/users socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix plugin: sieve: ~/.dovecot.sieve sieve_dir: ~/sieve Kind regards Pelle

[Dovecot] Allow POP3 per Domain
by Hauke Hagedorn 13 Jan '10

13 Jan '10

Hi List, I wonder, if it is possible to "switch" POP3 on or off for specific domains. Actually I want to disallow POP3-logins for a certain domain, whereas users can still login into a webinterface via IMAP. Curently I use Dovecot 1.1.11 on current Ubuntu 9.10 with a mySQL backend for authentication. With kind regards Hauke

[Dovecot] problems running dsync
by joakim＠verona.se 13 Jan '10

[Dovecot] Discard duplicate messages at delivery?
by Nicolas KOWALSKI 12 Jan '10

12 Jan '10

Hello, I am using dovecot 1.2.9, and the sieve plugin for filtering incoming messages into specific folders. The MTA is postfix, and deliver is called using the "mailbox_command = /usr/lib/dovecot/deliver" directive. Is it possible to make dovecot's deliver discard duplicate messages? With cyrus there is a duplicatesuppression directive which works well (http://cyrusimap.web.cmu.edu/imapd/overview.html#duplicate) With procmail, this can be done with the following recipe, but I did not found an equivalent for dovecot: # One often receives duplicate messages for cross-postings to mailing # lists, or explicit replies to a post from you in addition to the # mailing list message. # # The following recipe eliminates all duplicate messages. It tells # formail(1) to keep a cache file of the Message-IDs of the most # recent messages you've received. Since Message-IDs are guaranteed # unique for distinct messages, they are ideally suited to weed out # duplicates. # :0 Wh: msgid.lock | formail -D 65536 .saves.msgid Thanks, -- Nicolas

[Dovecot] Silent migration from mbox to maildir?
by Götz Reinicke - IT-Koordinator 12 Jan '10

12 Jan '10

Hi, after migrating to a new hardware (which is soo soooo mutch faster than the old one) I start to think about migrating from mbox to maildir. I'v read some docs and wikies and some questions are unanswered or maybe I skip the answers: - Is it possible to migrate the mboxes "silent" e.g. if a user logs in the mbox is converted? - regarding the Namespaces wiki article, it is possible to mix mbox and Maildir for one user. Is it possible to use this setup for all newly created accounts? or - Is it possible to have maildir set up for all newly created accounts while the old accounts still use mbox? Thanks for any suggestion and best regards, Götz -- Götz Reinicke IT-Koordinator Tel. +49 7141 969 420 Fax +49 7141 969 55 420 E-Mail goetz.reinicke(a)filmakademie.de Filmakademie Baden-Württemberg GmbH Akademiehof 10 71638 Ludwigsburg www.filmakademie.de Eintragung Amtsgericht Stuttgart HRB 205016 Vorsitzende des Aufsichtsrats: Prof. Dr. Claudia Hübner Staatsrätin für Demographischen Wandel und für Senioren im Staatsministerium Geschäftsführer: Prof. Thomas Schadt

[Dovecot] Dovecot Quota Problem
by Ken Price 12 Jan '10

12 Jan '10

I'm using Dovecot LDA with Exim. I'm also using Dictionary Quotas in a MySQL database. I want to avoid backscatter completely, so I set "quota_full_tempfail = yes" and handle quota checking in the Exim RCPT ACL during the SMTP session. The problem lies in the case where a user's account is nearly full. Smaller messages will continue to come through, but a larger message would get queued for retry since it will push the account over quota. I need Dovecot's quota to exhibit the same behavior as Exim's "quota_is_inclusive=false". >From Exim docs: quota_is_inclusive=false When this is done, the check for exceeding the quota does not include the current message. Thus, deliveries continue until the quota has been exceeded; thereafter, no futher messages are delivered. Any ideas on how I can implement this inside of Dovecot? Thanks, -Ken Price

[Dovecot] Problem in LSUB?

[Dovecot] Dovecot (IMAP) Hangs sometimes
by Mario Gomide 12 Jan '10

12 Jan '10

Hi there! I'm using Dovecot 1.0.7 in RHEL 5.4 64bits as a IMAP/POP3 server. Dovecot authenticates users against an AD server via kerberos (pam configuration) and clients connect to it via IMAPs and POP3s with SSL. Webmail is in localhost and connects locally also with SSL. All is fine and people use the email server normally and with no problems. But, I have noticed that dovecot hangs sometimes. Usually twice a day somewhere between 09:40 and 10:00 a.m and in the afternoon at about 3:00 p.m. The problem starts when webmail takes long to authenticate and show folders and stuff. After a while it times out and doesn't connect. Then the clients (e.g. outlook, thunderbird) start taking long to connect and then they timeout. Important: Only IMAP connections timeout! POP3 continues ok. This latency keeps on going until dovecot finally hangs (after about 10 to 15 minutes). The problem is solved when I restart/reload dovecot. I'm not sure as to what's going on! I check the log, but it has been hard to pinpoint an exact event or to detect when the problem begins. Any ideas? BTW: what's the real difference between reload and restart? Thanks a lot! Mario

Thanks Stephan, I have the extdata plugin compiled, and am now trying to make a global sieve script to test it. I'm running into problems when using sievec to compile the script - I'm not getting the plugin's variables that are provided in dovecot.conf's plugin {}.

I've traced it through sievec.c -> sieve_tool_sieve_env -> sieve_tool_get_setting -> getenv() call. More info: 1. I've traced the process, there's no attempt to open or stat any dovecot.conf 2. using tip dovecot-1.2, dovecot-1.2-sieve, pigeonhole-sieve-extdata. I pulled+updated & rebuilt and confirmed the above behaviour just prior to sending this message. 3. The test scripts run because the test framework uses the test_config mechanism to provide sieve_extdata_dict_uri. Any hints on how to get the dovecot.conf data to sievec? Thanks, -Martin Foster

[Dovecot] Same filenames on different servers?
by Alexander Chekalin 11 Jan '10

11 Jan '10

Hi, I'm really fuzzy about some problem on how Dovecot used to name files to store messages in Maildir. I have two identical servers (let's call them "First" and "Second"), and have Dovecot and Exim set up on both of them (Maildirs are used to store messages and boxes). First server is the server to be used by people around, and the Second server is backup one, the only thing it can do while the First is alive is to get (via rsync) First's mail spool. I set up rsync to run every 5 minutes, and that's quite well sync spools from First to Second. So if something wrong happens to First server we simple disconnect it from the network and put Second server in place of First. The problem is that files in Maildirs on First server are named like that: 1262610335.H798006P5447.first.domain.my,S=1962:2, 1262610402.H529761P5596.first.domain.my,S=2975:2, 1262610410.H787724P5657.first.domain.my,S=75691:2, ... and the files on Second server should be named like 1262610335.H798006P5447.second.domain.my,S=1962:2, 1262610402.H529761P5596.second.domain.my,S=2975:2, 1262610410.H787724P5657.second.domain.my,S=75691:2, ... As soon as I enter the Second's mailbox with IMAP client Dovecot used to rename files the way they should be. If after that I rsync spools I'll end up with double sized spool as there'll be both First and Second files: 1262610335.H798006P5447.first.domain.my,S=1962:2, 1262610335.H798006P5447.second.domain.my,S=1962:2, 1262610402.H529761P5596.first.domain.my,S=2975:2, 1262610402.H529761P5596.second.domain.my,S=2975:2, ... Long description for simple problem, yes :) I also tried to set: maildir_copy_preserve_filename = yes but still no luck. My setup is FreeBSD 7.2 with all versions in 1.1.x and 1.2.x branches (now it is 1.2.8). Thank you in advance for you advice, yours, Alexander

[Dovecot] sieve 0.1.14: vacation encodes Subject twice
by Roland Rosenfeld 11 Jan '10

11 Jan '10

Hi! I noticed the following problem in dovecot-1.2-sieve-0.1.14: The following vacation causes trouble with the Subject line: if not exists ["List-Id", "List-Post"] { vacation :days 7 :addresses ["test(a)netcologne.de"] :subject "=?utf-8?b?w4TDlsOc?= sadasd" "Bin gerade nicht hier."; } As you can see, the Subject is already MIME encoded according to RFC2047. Starting with sieve 0.1.14 the subject is now encoded by sieve again, so I get the following in my vacation mail: Subject: =?utf-8?q?=3D=3Futf-8=3Fb=3Fw4TDlsOc=3F=3D?= sadasd As you can see, the RFC2047 encoding is RFC2047 encoded, which results in an unreadable subject. According to RFC5230 section 4.3 this shouldn't happen: The ":subject" parameter specifies a subject line to attach to any vacation response that is generated. UTF-8 characters can be used in the string argument; implementations MUST convert the string to [RFC2047] encoded words if and only if non-ASCII characters are present. Implementations MUST generate an appropriate default subject line as specified below if no :subject parameter is specified. If I understand this right, sieve should do the RFC2047 encoding only if the string is non-ASCII. But the RFC2047 encoded string is already ASCII, so it should not be encoded a second time. I just compared this with sieve 0.1.13, which behaves different: It does not encode the Subject header at all. As long as the managesieve client (in our situation Horde/IMP) encodes the subject, everything works correct, while we run into trouble with 0.1.14. I think that there needs to some mechanism in sieve that checks whether the subject contains non-ASCII and does the encoding only in this case. I just checked out, that 0.1.14 does not encode a non RFC2047 encoded 7bit subject, while a 7bit subject starting with =?utf-8?... is encoded twice.

[Dovecot] dovecot cannot access a specific folder
by Spyros Tsiolis 11 Jan '10

11 Jan '10

Hello list, Has someone stumbled upon this before ? -- Jan 09 11:25:01 IMAP(postmaster(a)webmail.domain.gr): Error: stat(/var/MailRoot/domains/webmail.domain.gr/postmaster/Maildir/tmp) failed: Permission denied (euid=501(vmail) egid=502(vmail) missing +x perm: /var/MailRoot) -- "/var/MailRoot" is the root path/folder for XMail. An smtp/pop3 server. Should I go ahead and chmod the folder or should I try to find a more delicate solution to this ? Any help would be greatly appreciated, Regards, spyros

[Dovecot] How to create UTF encoded folders?
by Kārlis Repsons 11 Jan '10

11 Jan '10

Hey, as I understand from post [1], system folders with UTF-8 chars in their names will only be available for use with Dovecot2 and I certainly look forward to that, but somehow I was short of info about the current use of UTF characters like ā, Ž etc. Should I just omit thinking about modified-UTF-7, avoid those characters for the time being and then with Dovecot2 create UTF-8 encoded folders with MUA and also on fs? Or there is something to know anyway? Please suggest as it would be a pity not to create folders with utf symbols... [1] http://www.mail-archive.com/dovecot@dovecot.org/msg23576.html

[Dovecot] "leave mail on server" workaround
by Kirill Miazine 10 Jan '10

10 Jan '10

Hello, POP users often keep fetched mail on server, by checking for "leave mail on server" or similar option in their client. What would be the best way to disallow them using such approach. That is, what is the best way to force deletion of messages that have been RETRieved in a POP session at the end of that POP session? RETRieved messages will be marked as \Seen, but since users might also use an IMAP client (e.g. webmail), it'll be dangerous to simply delete all \Seen messages in user's mailbox. I'm all open for suggestions. -- -- Kirill Miazine <km(a)krot.org>

[Dovecot] How to tell dovecot to use a specific MTA
by Spyros Tsiolis 10 Jan '10

10 Jan '10

Hello again people, OK. I checked a lot of HOWTOs and documents. One specific document describes how one can make dovecot "talk" to postfix. The procedure is pretty straightforward (taken from the document) : -- . Configuring Postfix and Dovecot Turn off sendmail: service sendmail stop chkconfig sendmail off system-switch-mail (select postfix) -- This is for CentOS systems. My question is pretty simple. How exactly does someone tell dovecot (or the CentOS system) that the MTA used is not a pre-packaged postfix MTA but (in my case as you have pretty much discovered by now) XMail compiled from source (no pre-packaged version AFAIK for CentOS; but even if existed, I would still build it on my own) ? Any help would be appreciated, Regards, spyros

[Dovecot] IMAP client dependence on dovecot mail storage fromat?
by Kārlis Repsons 09 Jan '10

09 Jan '10

Hi, After setting up a maildir tree with :LAYOUT=fs and accessing it with KMail and Thunderbird, various mail client-specific problems appeared, but, as I didn't try with maildir++, I would like to confirm here: does that matter for an IMAP client much if I store mail on server as ":LAYOUT=fs" or maildir++? Can it see differences? I would like to think, that IMAP protocol should provide for all transactions in a standard way and its dovecot's/server's sole business how it stores mail locally. However... These results seem not very good: KMail: try creating a folder "sub" in "parrent" and you'll get "parrent.sub" along with "parrent" on server side. There, however, are no problems with Latvian unicode chars. Thunderbird: it can create a new folder in "parrent" as desired, but it can't display Latvian unicode chars (being such at server side) on client, while, if I try creating a new folder with Thunderbird with these chars, on server it will look somewhat like base64! So I'm really confused. All together these things are pretty frustrating, sure, but I'd like to understand whats the real problem here!

[Dovecot] Sieve > Pigeonhole > external storage with LDAP or other data source available to dovecot
by Martin F. Foster 08 Jan '10

08 Jan '10

I am looking at porting and generalizing an old in-house patch that I'm using for the CMU Sieve plugin. It allows sieve script to test & lookup arguments from LDAP. Before getting too involved in this, I'd like to discuss my goals here in the hopes that someone else also thinks this would be useful. Many heads may make better design? Goal: ------ Allows scripts which are still stored on the filesystem to lookup parameters stored in an LDAP directory. Useful if you provide a global sieve script to implement functions such as "vacation", forwarding to small groups (not a MLM), wish to toggle whether a message is kept in the mailbox after being forwarded, etc. <example> # determine if we always auto-respond, or if we respond with a more vacation-ish setting of every 30d # # sample LDAP entry: # uid: testuser(a)domain.com # mailResponderMode: vacation # mailResponderText: "I'm on vacation, far far from the Internet" (base64 encoded string...) # "always" reply mode, sanitized to once a day if ldap "mailResponderMode" "reply" { vacation :days 1 "ldap@mailResponderText"; } # traditional "vacation" mode, say reply once every 30d if ldap "mailResponderMode" "vacation" { vacation :days 30 "ldap@mailResponderText"; } </example> This introduces: 1. a new command "ldap", to lookup attributes and their values in an LDAP directory using the user's context 2. an extention to the vacation command that looks up the vacation reply text that is triggered by supplying "ldap@ldapAttribute" as the text. 3. other actions not shown above which extends redirect and a few other commands to lookup data from LDAP Related work: 1. Pigeonhole low priority TODO would like to implement alternate script storage, eg: LDAP & SQL. I'm not immediately interested in alternate types of script storage, but for what I want to acheive, I need to sanely access at least an LDAP directory. 2. draft-ietf-sieve-external-lists (http://tools.ietf.org/html/draft-ietf-sieve-external-lists-01) proposes a mechanism to pull mailing list addresses from external storage mechanisms such as LDAP, ACAP or relational databases. I'm interested in this, but would like to extend this functionality beyond just lists as the example above demonstrates. 3. there are security and resource consumption issues with doing this, suggesting that limits should be set, or the use may have to be restricted to global scripts eg: sieve_before or sieve_after The question: - do others on this list see value in the functionality described above? If there's some consensus that this would be useful, I'll flesh out howI think a generalized version of this old patch may behave, then (!) work on an implementation as a plugin to dovecot's sieve. cheers, -Martin Foster martin_foster(a)pacific.net.au martin.foster(a)pacnet.com

[Dovecot] stripping attachments
by Frank Cusack 08 Jan '10

08 Jan '10

there is a windows tool that strips attachments from emails on the server. i think it works for exchange. is there a tool or a way to do this for imap? i don't mean a mail filter that would strip them before the user sees them, i mean that the user could actively cooperate to reduce mail storage space, yet keep the original email on the server sans attachment.
