[Dovecot] crashes on 2.0.16
by Cor Bosman 31 Dec '11

31 Dec '11

Hey all, I upgraded some servers today from Debian Lenny to Debian Squeeze, and after the upgrade I started getting dovecot crashes. I was on 2.0.13 but got these there as well, and hoped upgrading to 2.0.16 would help. It didn't. Anyone have an idea?

[Dovecot] mbox, hierarchical folders/folders and IMAP
by Alexander Chekalin 30 Dec '11

30 Dec '11

Hello, I'm now dealing with funny problem. I try to use Dovecot (2.1.rc1, actually) and mbox format to store old mailing, to keep logic of "one folder = one file". If I'd choose Maildir, I'd be able to create hierarchical folders (like "OldMail -> Maillists -> Dovecot"), and in fact on disk such a folders would be stored as real folders with dots in their names. In PHP it is easy to create with "imap_createmailbox()" function, I'd simple fire it 3 times (for "OldMail", for "OldMail.Maillists" and for "OldMail.Maillists.Dovecot"). But when I do the same with mbox, in fact it creates separate files (indeed, named "OldMail", "OldMail.Maillists" and "OldMail.Maillists.Dovecot") instead of creating filesystem folders ("OldMail/Maillists/Dovecot"). PHP is not guilty, Thunderbird won't create such folders as well. I can only create folders myself (say, with mkdir in the shell), chown it, and the it perfectly works in IMAP. Now I just wanted to know, are there any way to create IMAP-folders and subfolders using standard IMAP functionality? Thank you, Alexander

[Dovecot] Using Amazon S3 storage for Maildir ?
by Forrest Aldrich 30 Dec '11

30 Dec '11

I wonder if anyone has tried using an IMAP server with Amazon S3 as a backend. There would be many factors to consider (speed, etc). However, moreso, I don't know that Maildir(++) would support multiple folders that might be linked into the cloud. For example, higher-I/O local incoming mail is on disk, some folders archived on S3. Could be easily done by simply creating another account and storing its Maildir in S3 -- Curious....

[Dovecot] How to serve a subset of IMAP folders for hand held devices.
by David Pottage 30 Dec '11

30 Dec '11

Hello I am currently running dovecot 1.2.15 on my home server. I have over 200 folders in personal email account, and I have found that my smart-phone does not work well trying to display that many folders. I solved the problem by creating a second instance of dovecot running on a non standard port, and configured it to serve only a subset my email folders, so that way the email client on my smartphone works well and I can read the emails I am interested in on the move. The process of configuring two instances of dovecot on the same machine serving different views of the same mailbox was faily complex, so I think it would be worth documenting the process in an FAQ or suchlike for other users. I thought a good place to write up my method would be in the HowTo section of the Dovecot Wiki. Is that a good idea? Can I request an account to edit the Wiki, or should I send a draft text to an editor? Are there any Dovecot experts here who can review my methods and suggest improvements? -- David Pottage

[Dovecot] /usr/lib/dovecot/imap ignores log settings?
by Asheesh Laroia 29 Dec '11

29 Dec '11

Hi Dovecot peeps, I'm enjoying running /usr/lib/dovecot/imap directly as a PREAUTH IMAP pipe. I find that it outputs log messages whose severity is INFO to stdout. I'm running it as follows: /usr/lib/dovecot/imap -c /tmp/dovecot.conf and I see the following messages output to stdout: * PREAUTH [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS] Logged in as paulproteus imap(paulproteus): Info: Connection closed bytes=0/305 Naturally, the first line is great. My /tmp/dovecot.conf is: <cut here> # single-dbox mail_location = sdbox:~/Maildir/dbox log_path = syslog info_log_path = /dev/null </cut> I'm also attaching strace output, created by running this command: echo | strace /usr/lib/dovecot/imap -c /tmp/dovecot.conf > /tmp/straced 2>&1 (The point of the "echo | " is to provide a newline and then EOF to /usr/lib/dovecot/imap.) You can see in the strace output that /usr/lib/dovecot/imap outputs the "Connection closed" message to file descriptor 2. I'd like that message to actually not be printed, which is why I set log_path to syslog. -- Asheesh.

[Dovecot] Received date no longer email date?
by Brian L. Matthews 29 Dec '11

29 Dec '11

I just upgrade from dovecot 1.2 to dovecot 2.0.16. I use dovecot as a local IMAP server to archive email from my corporate email account (on Exchange). I don't have any automated archiving, I just periodically move messages from my Exchange inbox to the IMAP inbox. I'm on Mac OS X 10.6.8 using Entourage as my mail client. In the previous version of dovecot, the Received date of the email was preserved when I moved a message, but it's not in 2.0.16, it's set to the date and time I move the message. If I open a message, the date displayed is the date on the message as expected. I converted my config from 1.2 with $ doveconf -n -c dovecot.conf > dovecot-2.conf It spit out various warnings but, once I'd created a dovenull user, seemed to work fine. Here's my configuration info: $ dovecot --version 2.0.16 $ dovecot -n # 2.0.16: /usr/local/etc/dovecot/dovecot.conf # OS: Darwin 10.8.0 i386 disable_plaintext_auth = no listen = 127.0.0.1 log_path = /var/log/dovecot.log mail_location = maildir:~/Maildir passdb { args = login driver = pam } service auth { user = root } service imap-login { process_limit = 16 } service imap { process_limit = 64 } ssl = no userdb { driver = passwd } I'd like to get it back to preserving the Received date, any help you can provide will be appreciated.

[Dovecot] proxying, SSL, and client certificate
by Mike Abbott 29 Dec '11

29 Dec '11

How do I configure dovecot-2.0.x to present a client SSL certificate when proxying? If dovecot on server1.example.com has: passdb { driver = static args = proxy=y host=server2.example.com nopassword=y ssl=yes } and dovecot on server2.example.com has: ssl_verify_client_cert = yes auth_ssl_require_client_cert = yes then when a client connects to server1 and authenticates, a connection is established to server2 but the SSL handshake fails because server1 doesn't present a client certificate. I don't see where ssl_client_ctx is tied to a client certificate in ssl-proxy-openssl.c. Thanks.

[Dovecot] Dovecot imap proxy to nginx, incompatible
by David Jonas 29 Dec '11

29 Dec '11

It appears that using dovecot to proxy to nginx imap proxy doesn't work. >From tcpdump and browsing the source it appears dovecot sends, C CAPABILITY\r\nL LOGIN <user> <pass>\r\n and nginx only responds to the CAPABILITY command. Is this a problem with dovecot sending the two commands without waiting for the first to complete or is it nginx's trouble with not handling it correctly? A quick test with a perl script confirms: #!/usr/bin/perl -w $|++; use IO::Socket; use strict; my ($host, $user, $pass) = @ARGV; my $s = new IO::Socket::INET(Proto => 'tcp', PeerAddr => $host, PeerPort => 143); die "Could not create socket $!\n" unless $s; while(<$s>) { print $_; last if /OK/; } print $s "C CAPABILITY\r\nL LOGIN $user $pass\r\n"; while(<$s>) { print $_; last if /OK/; } print $s "Q logout\r\n"; while(<$s>) { print $_; last if /OK/; } close($s); ## Output: * CAPABILITY IMAP4rev1 SASL-IR SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN NAMESPACE LOGIN-REFERRALS UIDPLUS LIST-EXTENDED I18NLEVEL=1 QUOTA AUTH=PLAIN C OK completed * BYE Q OK completed

[Dovecot] Corrupted index cache file and high CPU usage
by hydra 24 Dec '11

24 Dec '11

I suspect, that dovecot v2.0.16 under Linux (tested on Gentoo 3.0.4 Hardened, Gentoo 3.0.6, Gentoo 3.1.4) causes 100% cpu utilization when index.cache is broken and doveadm is lanched. Dovecot uses LDAP as the userdb and provides IMAP and LDA. Because each user has a quota, the doveadm's expunge functionality is used to get rid of old trashed mail.

When this happens, I cannot unmount the drive nor a system reboot works. Thank you !

[Dovecot] Limit maximum connections for user/IP on proxy
by Martin Abrahamsson 23 Dec '11

23 Dec '11

Hi, Is it possible to limit the maximum number of IMAP connections allowed for a user from each IP address, on the proxy server instead of on the mail store server? mail_max_userip_connections works well when the client is connection to the mail store without proxy, but when using proxies the POP/IMAP server will register the remote IP (rip) as the proxy server's IP address - thus a low limit will be reached quite easily. Thanks -- Martin Abrahamsson

[Dovecot] Patch for dovecot 1.2.16 (and .17) for vpopmail module
by Alessio Cecchi 22 Dec '11

22 Dec '11

Hi Timo, I love dovecot but I love also vpopmail and its functions for manage user limits (via vmoduser). Unfortunately in dovecot 1.2.x auth default set to use "vpopmail" is unable to apply this limits. Only if used with checkpassword limits works fine but in the dovecot.log only user (without @domain) is logged. So, based on the code of dovecot 2.0, I have created this very simple patch that correct this bug.

[Dovecot] Backing Up To Windows File Server
by Asai 22 Dec '11

22 Dec '11

Greetings, Working with dsync and setting up backups to a Windows file server. Problem seems to be that Windows is renaming the dovecot mail files (maildir) to Windows friendly filenames, and losing the Dovecot name. For example, 1323817925.M36368P32049.triata.globalchangemultimedia.net,S=2255,W=2318:2,S becomes 1AETPH~X. Does anyone have any ideas about how to tell Windows to not do this? Or is it not possible? -- --asai

[Dovecot] lmtp logging incomplete (does not tell what mailbox mail is actually being saved to!)
by Gary Chodos 22 Dec '11

22 Dec '11

We created a new virtual domain and created a user in that domain in our pgsql database. Instead of creating any directory structure in /home/virtual/mail/<domain>/<user>, I just sent a test email to see if dovecot's lmtp would autocreate. And it did! And mail appears to be delivered to an inbox.. but, logging is weird and I'm not sure everything is working as it should because: Dec 20 23:01:28 mx dovecot: lmtp(21458, user(a)example.com) lUDFG8tZ8U7SUwAAO3tENA: msgid=<20111221040122.GP13367(a)hostname.example.org>: saved mail to . so why doesn't dovecot log where mail is stored/saved? thanks, Gary

[Dovecot] Problem listing SPECIAL-USE flags
by Patrick Ben Koetter 21 Dec '11

21 Dec '11

Timo, we want to implement SPECIAL-USE in Thunderbird (TB), but we've run into problems. I believe you could help change that. Here's the problem: By default TB only lists subscribed (LSUB) folders when it accesses an IMAP server. However when I do a LSUB on recent Dovecot 2.1 code from mercurial I don't get to see the SPECIAL-USE flags. Therefore TB fails to identify which folders it should use and map to until someone tells it to list all folders (LIST) manually. Central part of the SPECIAL-USE idea was/is to require as little user interaction as possible to automatically setup a MUA to do the right thing. Speculating that probably most MUAs will do a LSUB by default and never will get to see SPECIAL-USE flags I think it is easier to have the server-side promote the flags. Do you think that would be possible? Just to verify I configured Dovecot as you would expect for SPECIAL-USE: I've set Dovecot 2.1 to autocreate and autosubscribe SPECIAL-USE mailboxes like this: namespace inbox { ... mailbox AltDrafts { special_use = \Drafts auto = subscribe } ... } This is what I get: * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE AUTH=PLAIN AUTH=LOGIN AUTH=CRAM-MD5] Dovecot 2.1 ready. t1 login alice(a)example.com secret t1 OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS FUZZY SPECIAL-USE] Logged in t2 LSUB "" "%" * LSUB () "."

[Dovecot] compile dovecot-sieve for dovecot 1.2.9 (ubuntu pkg)
by Julien Lacroix 21 Dec '11

21 Dec '11

Cheers, I've a running Dovecot 1.2.9, installed from the ubuntu 10.04 Lucid LTS repository and trying to get the dovecot-sieve plugin (which seems to be not included in the lucid repo) compiled. Method 1 listed in http://wiki.dovecot.org/LDA/Sieve/Dovecot wont work, seems the rpm was build without --enable-header-install Is it sufficient to download the sources from http://archive.ubuntu.com/ubuntu/pool/main/d/dovecot/dovecot_1.2.9.orig.tar… and use them for ./configure --with-dovecot=$path ? thanks and happy holidays julien

[Dovecot] Can I block dovecot from deleting read messages, after being fetched?
by Vasiliu Adrian 21 Dec '11

21 Dec '11

Hi all, Is there an option to disable (server-side) the deletion of read mails after fetching them via POP3, regardless of the MUA config? Here are the issues I'm facing: - my boss wants to force everyone into a server-side "no delete message"-policy, for archiving, auditing and backup&recovery purposes - the requisite here is pop3, so imap is out - the mailusers are virtual users (held in a mysql db) - don't have the budget to set up a separate mail-arvhing server - don't want to use shaggy ways (aka immutable flag, r/w permissions for Maildirs, etc) dovecot --version 2.0.15 Help? Thanks!

After the imap_open() invocation, you should check for error messages in your PHP logs, or dump all the errors using imap_errors(); Without more details, I would say you dropped one of those /option-flags or got the mailbox argument syntax wrong.

[Dovecot] Mail lost - maybe a bug???
by Marco Carcano 21 Dec '11

21 Dec '11

Hello everybody I'm struggling against what seems a really serious trouble: sometimes mail get lost I did all the possible checks, but they seems really lost - I know is absurd, but it seems so it has been noticed by two users on my server: intially I tought that was their mistake (mail deleted, mail into spam, ecc), but it wasn't I deeply checked mail logs, and it seems that mail are delivered (the path is postfix->amavis->dovecotlda) - log files says that messages are delivered, but sometimes we lost a message. I also tried to get into the Maildir and grep the subject of the lost email: if it was addressed to more recipients I'm able to get it on some of them, but not to all (look at the example below) I hope I have clearly explained everything, otherwise let me knowmydomain now an extract from the log file: Oct 27 11:20:29 srv001 postfix/smtpd[24562]: connect from usstlz- psecap06.emerson.com[144.191.128.17] Oct 27 11:20:30 srv001 postfix/smtpd[24562]: CE0B74E4A9F: client=usstlz-psecap06.emerson.com[144.191.128.17] Oct 27 11:20:31 srv001 postfix/cleanup[25157]: CE0B74E4A9F: warning: header Subject: =?utf-8?B?

[Dovecot] APOP and AuthDatabase/SQL
by Peter Smith 21 Dec '11

21 Dec '11

Hi, We're running dovecot 1.2.15 and use SQL authentication. We'd like to be able to support APOP, but can't see how this would fit in with SQL auth. Currently we have: password_query = SELECT email as user, password FROM virtual_users WHERE email='%u' or (email LIKE '%n@%%' AND unhashed='%w') It seems that in order to auth APOP logins, we'd need to access variables containing the authentication string sent by the client, and also variables containing the auth string sent in the POP3 greeting. Incidentally, the RFC (1939) suggests using: <pid.time@hostname> for the greeting, but it looks as if dovecot uses something else? I'm seeing greetings such as: +OK Dovecot ready. <260f.4abcc.4ef11550.cJD6sQSUSnmPS1B/5RGF0Q==(a)myhostname.com> base64 encoding? Thanks in advance, Peter Smith

[Dovecot] Sieve too rfc compliant ;-)
by Jan-Frode Myklebust 20 Dec '11

20 Dec '11

It seems we have a few email addresses that are not RFC 5322 compliant, and now that we've started using sieve these are failing. The problem is that we have a few addresses with leading, trailing or double dots in the local part: jan..frode(a)tanso.net .janfrode(a)tanso.net janfrode.(a)tanso.net I believe these has been working fine with everything else in dovecot (lda, lmtp, imap, pop), but that sieve is more strict. I think it's fair enough that it's strict with messages generated by sieve scripts, but it would be nice if it could be more tolerant with messages addressed for the sieve script. So, is there any setting for making it more tolerant ? -jf

I have tried with doveadm force-resync, maybe this could solve this issues. All of those should be fixed automatically. Do they keep happening if you don't do force-resync? How often do they happen anyway? Do they happen at any specific times (e.g. during doveadm purge)?

Hi, I'm strugling to find some documentation on dovecot's anvil service and/or its penalties (that can be checked with doveadm penalty) ... but i'm not finding anything on that. is there any documentation on anvil/penalties that i should check other than a few messages on the mailing list archive ? thanks ! -- Atenciosamente / Sincerily, Leonardo Rodrigues Solutti Tecnologia http://www.solutti.com.br Minha armadilha de SPAM, NÃO mandem email gertrudes(a)solutti.com.br My SPAMTRAP, do not email it

[Dovecot] Dovecot 2.1rc1 + 2.0.16 woes regarding fts_squat
by Robin 20 Dec '11

20 Dec '11

I can confirm the report posted in http://dovecot.org/list/dovecot/2011-November/062263.html that fts_squat no longer seems to be used after moving from 2.0.16->2.1 rc 1. I don't see crash reports in the logs, just "0 messages indexed". My search test tool just does a normal IMAP SEARCH for a long non-existent string. If there's another way to trigger re-indexing in 2.1, I don't see anything in the documentation for it. I've enabled mail_debug, but no log entries that shed light on the problem are available. Has the configuration for fts_squat changed? If anyone has a working fts_squat setup with Dovecot 2.1rc1, I'd appreciate hearing how you have it setup and working. During a large mail import with 2.0.16 today, I ran across a worrying message in the logs during an fts_squat reindex: out of memory. The plugin doesn't obey the mmap_disable configuration directive, which I've confirmed in the plugin source. The mailbox in question has only 17GB (mdbox style), with about 90,000 emails in it. Its "index" (for the purposes of normal IMAP retrieval as opposed to IMAP TEXT/BODY searching) is fine and uncorrupted. I freshly import these mailboxes between test iterations and any version changes anyway, so if there's corruption, it's happening within dovecot only. I'm using use Mail::IMAPClient to create + append mail over localhost, not any direct mdbox conversion trickery. In looking through the code, I see that mmap() is called for the *ENTIRE FILE*, which is guaranteed to fail on large indexes. I assume this was done out of expedience, but it's a "risky" sort of thing to do in a server process, even if 8GB RAM systems do seem to grow on trees. I intend to put this to work in a large installation (>10K users), so this IS of some concern for me in the long-term.

[Dovecot] Question about index reset in dovecot 2.0.15

[Dovecot] doveadm quota does not list all accounts
by Nikolaos Milas 20 Dec '11

20 Dec '11

Hello, I am running dovecot-2.0.13-1_128.el5 x86_64 RPM on CentOS 5.7. All accounts are virtual, hosted on LDAP Server. My problem is that the command: doveadm quota get -A stopped listing all accounts. I think this problem started after I changed in LDAP lookup configuration from "scope = subtree" to "scope = onelevel", because it did not occur before (I did no other changes). Now, the above command only lists 12 accounts. If I query for a particular user: doveadm quota get -u userx this works fine, but userx (and all users except those 12) is NOT listed when trying to display all users. How can I run the above command without problems again? Thanks in advance, Nick

[Dovecot] Quota PostgreSQL INSERT trigger
by Adis Nezirovic 20 Dec '11

20 Dec '11

Wiki instructions for creating insert trigger for PostgreSQL are wrong http://wiki.dovecot.org/Quota/Dict Calling INSERT on the table from within BEFORE INSERT trigger creates cascading trigger. http://www.postgresql.org/docs/current/interactive/trigger-definition.html Instead, one should return NEW record from the trigger, and it will be inserted after trigger execution. --- CREATE OR REPLACE FUNCTION merge_quota2() RETURNS TRIGGER AS $$ BEGIN IF NEW.messages < 0 OR NEW.messages IS NULL THEN -- ugly kludge: we came here from this function, really do try to insert IF NEW.messages IS NULL THEN NEW.messages = 0; ELSE NEW.messages = -NEW.messages; END IF; return NEW; END IF; LOOP UPDATE quota2 SET bytes = bytes + NEW.bytes, messages = messages + NEW.messages WHERE username = NEW.username; IF found THEN RETURN NULL; END IF; BEGIN IF NEW.messages = 0 THEN RETURN NEW; ELSE NEW.messages = - NEW.messages; RETURN NEW; END IF; EXCEPTION WHEN unique_violation THEN -- someone just inserted the record, update it END; END LOOP; END; $$ LANGUAGE plpgsql; DROP TRIGGER IF EXISTS mergequota2 ON quota2; CREATE TRIGGER mergequota2 BEFORE INSERT ON quota2 FOR EACH ROW EXECUTE PROCEDURE merge_quota2(); --- Best regards, Adis

[Dovecot] Tuning Login processes for High-performance Mode
by Alessio Cecchi 20 Dec '11

20 Dec '11

Hi, I'm working for tuning a busy cluster of dovecot servers. Heach server as 4 core, 8GB of RAM and provide POP3 and IMAP access to mailbox. OS is Debian 6.0 and dovecot version is 1.2.15. I am unsure how to set "login_max_processes_count" and "login_max_connections" for reach the best situation when login_process_per_connection is set to no. I don't know what value to set login_max_processes_count. For example is better the first or the second configuration? login_process_per_connection=no login_processes_count=4 login_max_processes_count=8 login_max_connections=512 login_process_size=128 login_process_per_connection=no login_processes_count=4 login_max_processes_count=16 login_max_connections=256 login_process_size=128 Which is a suggested ratio from login_max_processes_count and login_max_connections ? Other values are correct?

[Dovecot] Calculation of suggested vsz_limit values
by Nikolaos Milas 20 Dec '11

20 Dec '11

Hello, I would like to ask on suggested vsz_limit values. Is there any way of calculating such values? How should we determine them? I don't want to risk wrong values (and possible errors) on a production system, if I upgrade to 2.0.16 where vsz_limit values are enforced (I read release notes)! If there is no standard way of calculation, could someone please check the following info and suggest some values? I am running dovecot-2.0.13-1_128.el5 x86_64 RPM on CentOS 5.7 (as a VM on a KVM Host). All accounts are virtual, hosted on LDAP Server. We have about 250 mailboxes of 4GB each (in practice, only a couple of mailboxes ever reach 1GB so we are "over-booking"). It is a relatively low-load server. Memory status and config follows below.

[Dovecot] Strange Login / Timeout Sessions
by Carlos Mennens 20 Dec '11

20 Dec '11

I have my webmail application tied to Postfix / Dovecot server & now for some reason the IMAP sessions oddly time out throughout the day and then logging back into the mail system over the web is painfully slow. The only thing I've seen that fixes it is to reload the Dovecot daemon in Linux: /etc/init.d/dovecot reload Once that command is ran, my webmail login is super fast and moving from folder to folder is extremely fast again. Then in about a few hours, the session will time out and this problem repeats. The problem is the same for everyone and not just a few user accounts. Anyone have any idea what I should be looking for or looking at? My Dovecot logs or mixed in /var/log/maillog which is extremely hard to watch live & gets mixed with Postfix, Amavisd, and Postgrey. Any ideas or suggestions to narrow this problem out? I'm running Dovecot-1.0.7-7.el5_7.1. I saw this load on the console today: Error: Dovecot is already running with PID 2334 (read from /var/run/dovecot/master.pid) Fatal: Invalid configuration in /etc/dovecot.conf Below is my configuration file: [root@mail ~]# dovecot -n # 1.0.7: /etc/dovecot.conf protocols: imap ssl_ca_file: /etc/ssl/certs/digicert.crt ssl_cert_file: ***OMIT*** ssl_key_file: ***OMIT*** login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login mail_location: maildir:~/Maildir auth default: mechanisms: plain login passdb: driver: pam userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix

[Dovecot] Two important new Pigeonhole v0.3 features
by Stephan Bosch 19 Dec '11

19 Dec '11

Hello Dovecot users, Pigeonhole v0.3 for Dovecot v2.1 has two new features I would like you to play with before I make a first release: 1) The new Sieve editheader extension (http://tools.ietf.org/html/rfc5293) This allows modifying the headers of the message before delivery. This is actually the first implemented extension that can modify the message itself in any way. This feature adds quite a bit of new code that I'd like to see tested more thoroughly. 2) The new sieve-filter tool (documented in the sieve-filter(1) man page upon installation). This allows (re-)filtering messages that are already stored in a particular mailbox. It preserves the assigned IMAP flags and keywords and using the imap4flags extension these can also be modified. It also plays nice with the editheader extension. Judging by postings in this mailing list from the last few years, this is a highly-demanded feature and I'm glad that I finally got around to finish this thing. If the new sieve-filter tool is lacking certain features in your opinion, just let me know. Needless to say: read the man page carefully and watch out with important mail. This is currently only available from the mercurial repository, but if you prefer to have an .rc1 release first, just tell me and I'll make one. The automatic Debian repository already includes these features. Regards, Stephan.

[Dovecot] IMAP and sieve
by moozer 19 Dec '11

19 Dec '11

I am currently setting up an IMAP server for archiving purposes. The goal is to drag an email to the IMAP folder, and then have a server-side sieve script to put it in the right folder. One of the sources used was this wiki entry http://wiki.dovecot.org/LDA/Sieve/Dovecot I added the mail_plugins = sieve to /etc/dovecot/15-lda.conf and after some exim4 fiddling, mails delivered are filtered by my sieve script. Doing the same for imap delivery (in /etc/dovecot/20-imap.conf) give the following error Dec 19 10:22:09 leon dovecot: imap: Error: dlopen(/usr/lib/dovecot/modules/lib90_sieve_plugin.so) failed: /usr/lib/dovecot/libdovecot-sieve.so.0: undefined symbol: mail_deliver_save_open Dec 19 10:22:09 leon dovecot: imap: Error: Can't load plugin sieve_plugin: Plugin is intended to be used only by binaries: lda lmtp (we're imap) Dec 19 10:22:09 leon dovecot: imap: Fatal: Couldn't load required plugins Dec 19 10:22:10 leon dovecot: imap: Error: dlopen(/usr/lib/dovecot/modules/lib90_sieve_plugin.so) failed: /usr/lib/dovecot/libdovecot-sieve.so.0: undefined symbol: mail_deliver_save_open Dec 19 10:22:10 leon dovecot: imap: Error: Can't load plugin sieve_plugin: Plugin is intended to be used only by binaries: lda lmtp (we're imap) Dec 19 10:22:10 leon dovecot: imap: Fatal: Couldn't load required plugins I notice this part: "plugin is intended to be used only by binaries: lda lmtp (we're imap)" So the question is if it is possible to run sieve server-side sieve scripts on emails copied using IMAP. Suggestions are most welcome. Moozer -- I am running debian testing # dovecot --version 2.0.15

[Dovecot] DKIM Verification failures
by Nikolaos Milas 18 Dec '11

18 Dec '11

Hi, -- This message refers to the maillist itself rather than to dovecot software -- I have noticed that when I post to this list (only), I get DKIM Verification failure reports from: root(a)moncton.sidefx.com (e.g. for my last post: "DKIM failure report for job 4D27B5DC4E on mail.sidefx.com") root(a)mail.rmacd.com (e.g. for my last post: "DKIM failure report for job B69B3187F1 on mail.rmacd.com") root(a)mx0.roessner-net.de (e.g. for my last post: "DKIM failure report for job 6103B52092 on mx0.roessner-net.de") I have not had other DKIM failure reports from anywhere and I know that we should not have issues with it. An example from gmail: Authentication-Results: mx.google.com; spf=pass (google.com: best guess record for domain of nmilas(a)noa.gr designates 195.251.204.235 as permitted sender) smtp.mail=nmilas(a)noa.gr; dkim=pass header.i=(a)noa.gr So, whom should I contact to investigate this problem? Thanks, Nick

[Dovecot] logging deletion of emails through IMAP?
by John Brock 16 Dec '11

16 Dec '11

Version 1.2.16: Is there some way to enable logging for when emails are deleted via IMAP? All I see are log entries for users logging in/logging out. It would be nice to know when an email is deleted, and from which IP address the user was logged in when s/he deleted the email. -- John Brock Adeptive Software 303-554-0301 x1
