[Dovecot] Limiting the size of index files
by Edgar Fuß 21 Nov '07

21 Nov '07

Is there a way to limit the amount of disc space dovecot will use for its index cache? Other than putting that on a separate partition, I mean. We host our mail data on the file server, however, the index files are located on local discs on each of the mail servers and seem to grow without bounds. We're above 250M now and soon /var will run out of space. Thanks for any help.

[Dovecot] Problem Running Dovecot 1.0.5
by dave 21 Nov '07

21 Nov '07

Hello, When trying to run dovecot I am getting the following error :- Error: Error in configuration file /usr/local/etc/dovecot.conf line 923: Unknown section type (section changed at line 923) Fatal: Invalid configuration in /usr/local/etc/dovecot.conf The following section is at line 923. userdb static { args = uid=5000 gid=5000 home=/var/spool/vmail/%d/%n allow_all_users=yes } It seems to be that dovecot does'nt understand the section, but I configured with support for static userdb and this was confirmed before compilation took place. OS is Solaris 9. Any advice would be appreciated. Thanks, David.

[Dovecot] Problems executing dovecot.
by Marcelo Iturbe 21 Nov '07

21 Nov '07

Hello, I am running OS: Ubuntu 6.06.1 LTS dovecot # 1.0.7 Beta Problem: I have all the email delivery set up with maildir. I currently have an account which has 297,261 emails in the Inbox. Here is a transcript of a telnet session with the server: * OK Dovecot ready. 110 login somelameuser lameuserspass 110 OK Logged in. 111 select inbox * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 297261 EXISTS * 149522 RECENT * OK [UNSEEN 1] First unseen. * OK [UIDVALIDITY 1188426666] UIDs valid * OK [UIDNEXT 301157] Predicted next UID 111 OK [READ-WRITE] Select completed. 112 copy 1:100 toBeProcessed Connection to host lost. I keep getting dropped... My original idea was to move the files via command prompt, but I wasn't sure if that was allowed, thought I might mess up the UIDs. How could I move the emails into other directories (folders) so that a regular IMAP conector can process the emails?

[Dovecot] Received Dates/Squirrelmail
by Jeff Grossman 21 Nov '07

21 Nov '07

I am trying to figure out an issue I have with the e-mails in my inbox showing up in Squirrelmail. I sometimes get (more often than I care for it to happen) e-mails which show up as new either many hours ago or days ago. I have one particular e-mail that in Squirrelmail is showing a data of Tue, 8:23PM. The received header of that e-mail shows: Received: from murphy.debian.org (murphy.debian.org [70.103.162.31]) by apple.stikman.com (8.14.1/8.14.1/Debian-9) with ESMTP id lA1JGTli011052 for <x>; Thu, 1 Nov 2007 12:16:35 -0700 And the date header of that e-mail shows: Date: Tue, 30 Oct 2007 23:23:11 -0400 I have tried changing the Squirrelmail setting under Display Settings which says Use Received Date. Both options, yes and no makes the mail display the same way in Squirrelmail. Is this a problem with the way Dovecot is sending the information to Squirrelmail, or is this a problem with the way Squirrelmail is interpreting the data from Dovecot? Dovecot version is 1.1beta5 Squirrelmail is version 1.4.11 Thanks for any help you can offer me. Jeff

[Dovecot] Throttle New Connections?
by Joe Allesi -X (joallesi - Coyote Creek Consulting at Cisco) 21 Nov '07

21 Nov '07

All, Is anyone using iptables (recent module), or any other alternatives, to throttle the number of new imap or pop connections per minute? We have some applications that like to login every second to pull mail using imap, so we'd like to protect the entire dovecot server from these applications. We've already made the change over to high-perf mode, but we still need some type of denial of service protection. Any real-world data would be appreciated. Thanks!

[Dovecot] Just getting started
by Randall Donaldson 20 Nov '07

20 Nov '07

This is my first attempt at creating a mail server. I'm running postfix and dovecot on Fedora 7. So far the process has been very enlightening. I currently have the server able to send and receive messages for a domain from the server machine itself. In addition, I can SMTP from any client set up on the LAN by logging in. However, I cannot retrieve messages from remote clients on the LAN. Thunderbird reads "Connected to" {servername} across the bottom, then times out. I tried to telnet to port 110 on the server, and I no response, just hangs. Not sure where the problem lies. Thanks for any assistance. here's the output of dovecot -n: # 1.0.7: /etc/dovecot.conf 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_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/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 auth default: passdb: driver: pam userdb: driver: passwd Randall Donaldson Information Technology Stolze Printing

[Dovecot] How to write plugin

Hi, Where can I find documentation for plugin writers? Now I see mail-log-plugin source, but I can't understand how entry points (functions mail-log-plugin-init and mail-log-plugin-deinit) are defined to execute some actions on load/unload/copy messages. Can anybody comments this?

[Dovecot] Helping OS's page cache
by Timo Sirainen 20 Nov '07

20 Nov '07

http://dovecot.org/patches/1.1/fadvise.diff http://dovecot.org/patches/1.0/fadvise.diff These patches try to tell kernel when mail files are wanted to be read and when they're wanted out of memory, so the memory could be used for more important things such as index files. I'd like to hear if someone sees any actual changes (for better or worse) in the system load because of this. I'm not sure if I should add this to v1.1 and if it should be enabled by default.

[Dovecot] imap process consuming 100% CPU (Dovecot 1.0.3)
by Robert Tomanek 20 Nov '07

20 Nov '07

Hi, I have yet another problem with Dovecot: sometimes (rarely, maybe once every few days) one of the imap processes will 'hang', consuming all available CPU time. It does not seem to 'finish' in any reasonable amount of time (in one instance I waited a few days). This process will not even exit gracefully, it needs to be killed with 'kill -9 <PID>'. It has just happened again.

[Dovecot] mail_location backends
by Harrison Metzger 19 Nov '07

19 Nov '07

Hello, Where I work we have have an interesting setup, we have 2 machines with mail accounts on them and both have dovecot. We would really like to centralize all the mail accounts on one machine, but unfortunately the administration has not approved it. However, if we could create the "illusion" that they are on the same machine that would be acceptable. If we have a 3rd machine, lets say called mail.example.com, could we install dovecot on it (using LDAP authorization), such that when a user connects to this machine, it then connects to one of the 2 other machines to retrieve their mail (instead of reading from /var/spool/mail). So in essence, the mail backend is just another POP or IMAP server. In the ldap directory we could have a field that says the mail location is: "imap://machine1.example.com" for some users and "imap://machine2.example.com" (Of course it dosent have to look like that, but I hope you get my idea), then dovecot would make a connection to those servers and read the user's mail. Does such a backend even exist? Can dovecot's plugin support register a mail_location backend (such as mbox:/blah/blah, ...)? Harrison Metzger

[Dovecot] MANAGESIEVE patch v9 for dovecot 1.0.7
by Stephan Bosch 19 Nov '07

19 Nov '07

Hello Dovecot users, Since v8, I have updated the MANAGESIEVE patch to fix various issues reported by users. Although I planned to upgrade the next release after v8 to Dovecot v1.1, I release these changes for Dovecot 1.0 first. If no further major issues are found, I can upgrade to Dovecot 1.1. Change Log V9 ------------- + Definitively fixed the segfault mentioned in V8. It proved to be very time-constrained and thus hard to reproduce. The error turned out to be related to the input handling of the login daemon during authentication. + Checked for changes in the imap daemon that weren't propagated to the managesieve implementation due to code duplication. + Fixed a bug in the autodetection of the sieve storage location. + Fixed bug in the sieve storage that failed to refresh the symlink if the storage was moved. + Improved error handing in the sieve-storage implementation in various places. + Fixed the situation in which the active script link is located in the sieve storage. + Added managesieve configuration to dovecot-example.conf and made the example in this file more concise. This patch still includes (yet another) instance of the CMU Sieve source, as explained in one of my previous e-mails (http://dovecot.org/list/dovecot/2006-July/015016.html) The latest patch can be downloaded at: http://sinas.rename-it.nl/~sirius/ The README.managesieve is located in the root of the dovecot source tree after applying the patch. The dovecot-example.conf file is updated with a configuration example for managesieve. Have fun testing the patch. Don't hesitate to notify me when there are problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl IRC: Freenode, #dovecot, S[r]us

[Dovecot] unlink_directory(....Trash.NewFolder) failed: Directory not empty
by Adam McDougall 18 Nov '07

18 Nov '07

I noticed the following this week. No idea how long its been happening because I have not tested deleting folders hardly at all. Steps to reproduce: 1. Create a folder "NewFolder", click on it in thunderbird so an index dir is created: ls -ldi Maildir/.NewFolder/ 1504062 drwx------ 5 mcdouga9 egrstaff 4096 Nov 16 19:44 Maildir/.NewFolder/ ls -ldi Maildir/dovecot/boomhauer/private/indexes/.NewFolder/ 4198832 drwx------ 2 mcdouga9 egrstaff 4096 Nov 16 19:44 Maildir/dovecot/boomhauer/private/indexes/.NewFolder/ ls -li Maildir/dovecot/boomhauer/private/indexes/.NewFolder/ total 0 4198833 -rw------- 1 mcdouga9 egrstaff 128 Nov 16 19:44 dovecot.index.log 2. Delete "NewFolder" which makes Thunderbird move both the folder under Trash, and seems to "rename" the .NewFolder index dir to .Trash.NewFolder (same inode #): ls -ldi Maildir/.Trash.NewFolder/ 1504062 drwx------ 5 mcdouga9 egrstaff 4096 Nov 16 19:44 Maildir/.Trash.NewFolder/ ls -ldi Maildir/dovecot/boomhauer/private/indexes/.Trash.NewFolder/ 4198832 drwx------ 2 mcdouga9 egrstaff 4096 Nov 16 19:44 Maildir/dovecot/boomhauer/private/indexes/.Trash.NewFolder/ ls -li Maildir/dovecot/boomhauer/private/indexes/.Trash.NewFolder/ total 4 4198833 -rw------- 1 mcdouga9 egrstaff 128 Nov 16 19:44 dovecot.index.log 3. Right click on Trash folder in Thunderbird, choose "Empty Trash": Nov 16 19:47:25 boomhauer dovecot: IMAP(mcdouga9): unlink_directory(/home/mcdouga9/Maildir/dovecot/boomhauer/private/indexes/.Trash.NewFolder) failed: Directory not empty ls -ldi Maildir/.Trash.NewFolder/ 1504062 drwx------ 5 mcdouga9 egrstaff 4096 Nov 16 19:44 Maildir/.Trash.NewFolder/ ls -ldi Maildir/dovecot/boomhauer/private/indexes/.Trash.NewFolder/ 4198832 drwx------ 2 mcdouga9 egrstaff 4096 Nov 16 19:47 Maildir/dovecot/boomhauer/private/indexes/.Trash.NewFolder/ ls -li Maildir/dovecot/boomhauer/private/indexes/.Trash.NewFolder/ (sometimes has a .nfs.blahblah file, I think I failed to catch it quick enough this time) The folder dissapears from Thunderbird's view but stays on disk, and will reappear in Thunderbird if you collapse and re-expand the folder tree, or close and open thunderbird.

[Dovecot] SIGSEGV (Segmentation fault) with antispam plugin
by Boky 18 Nov '07

18 Nov '07

Hi all. I am trying to get dovecot (1.0.rc17) running with antispam plugin. I have created another backend, which executes "sa-learn" from spamassassin's arsenal. The backend is modeled after sendmail backend. But I can't seem to get the plugin working wit either my backend or signature-log.

[Dovecot] crash with fts_squat on an identified email
by Adam McDougall 18 Nov '07

18 Nov '07

I have some folders with a good amount of spam. While demonstrating full text search to a user, we found a folder that would crash dovecot while doing a fts. While splitting up the mailbox to narrow it down, I found there are a good number of messages in that folder that all made it crash in the same manner. I figured I'd narrow down a single one, get that fixed, then retest the rest. I also added to my todo list to try a full text search on as much email as I can find, to try to weed out any other problems (and see if fts is realistic to use in production). Nov 17 09:03:26 boomhauer dovecot: IMAP(mcdouga9): file message-decoder.c: line 201 (translation_buf_decode): assertion failed: (*size >= skip) Nov 17 09:03:26 boomhauer dovecot: child 14668 (imap) killed with signal 6 Let me know if this is not reproducable with the attached tgz containing a maildir with one message, I could do a local gdb if needed.

[Dovecot] mailbox size limit
by Bazy 18 Nov '07

18 Nov '07

Hi guys, I was wondering... my Inbox is 1.3GB large, my mailbox size limit is 6GB (6442450941). Other users have 500+ MB in their Inbox. I have about 27GB of mail. I'm running dovecot 1.0.7 now under Fedora 7 with postfix. I have no trouble at all, everything is working perfect. I use ext3 as my file system, and I store mail in maildir format. Will I have any inode, file system, issues? Is anyone storing more then 27GB in maildir format on only one ext3 partition? Here is my dovecot -n output: # 1.0.7: /etc/dovecot.conf log_path: /var/log/dovecot.log log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 ssl_cert_file: /etc/postfix/smtpd.cert ssl_key_file: /etc/postfix/smtpd.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 login_max_processes_count: 512 mail_location: maildir:/home/vmail/%d/%n/ mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/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/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 imap_client_workarounds(default): outlook-idle delay-newmail imap_client_workarounds(imap): outlook-idle delay-newmail 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 passdb: driver: sql args: /etc/dovecot-sql.conf userdb: driver: sql args: /etc/dovecot-userdb-sql.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix plugin: quota: maildir:storage=102400 [root:pts/0][~]# cat /etc/dovecot-sql.conf driver = mysql connect = host=/var/lib/mysql/mysql.sock user=mail_admin password=XXXXXXXX dbname=mail default_pass_scheme = CRYPT password_query = SELECT password FROM users WHERE CONCAT(SUBSTRING_INDEX(email,'@',1)) = '%n' AND CONCAT(SUBSTRING_INDEX(email,'@',-1)) = '%d'; [root:pts/0][~]# cat /etc/dovecot-userdb-sql.conf driver = mysql connect = host=/var/lib/mysql/mysql.sock user=mail_admin password=XXXXXXXX dbname=mail user_query = SELECT CONCAT(('/home/vmail/'), SUBSTRING_INDEX(email,'@',-1),'/',SUBSTRING_INDEX(email,'@',1),'/') as home, 5000 as uid, 5000 as gid, CONCAT('maildir:storage=', floor(quota/1024)) as quota FROM users WHERE email = '%u';

[Dovecot] Path to public folder subscription file not created in 1.1b7?
by Adam McDougall 17 Nov '07

17 Nov '07

I use CONTROL=%h/Maildir/dovecot/public/control/[namespace] for each of my public namespaces. A few nights ago, I noticed having a new user subscribe to public folders for the first time will silently fail, becuase the path up to the subscriptions file will not be created. I am pretty sure dovecot used to create it for me, but maybe that changed in a recent version, or maybe I did something to break it? Work around is to mkdir -p /home/[user]/Maildir/dovecot/public/control/[namespace] but I'd like to avoid having to do that. Once I create the directory and make sure it is writable, the client can subscribe to public folders in that namespace. If they do not have permission, it still silently fails. namespace: type: public separator: / prefix: #shared/decs/ location: maildir:/egr/mail/shared/decs:CONTROL=%h/Maildir/dovecot/public/control/decs:INDEX=%h/Maildir/dovecot/%q/public/indexes/decs list: yes subscriptions: yes

[Dovecot] Mail.app IDLE support
by Martin R. Ehmsen 16 Nov '07

16 Nov '07

Hi, I'm trying to use the new IDLE support in Mail.app on Mac OS 10.5, and it works sort of, but it seems to miss some notifications. My guess is the IDLE support in Mail.app is implemented such that it sets up a connection for IDLE notifications and then checks the mail via another connection, and because of that the "IDLE-connection" gets disconnected for inactivity after 30 min. The reason for my guess is that I get the following in my logs: dovecot: Nov 14 17:00:29 Info: imap-login: Login: user=<amanda>, method=PLAIN, rip=::ffff:xxx.xxx.xxx.xxx, lip=::ffff:192.168.1.2, TLS dovecot: Nov 14 17:00:29 Info: imap-login: Login: user=<ehmsen>, method=PLAIN, rip=::ffff:xxx.xxx.xxx.xxx, lip=::ffff:192.168.1.2, TLS dovecot: Nov 14 17:00:30 Info: imap-login: Login: user=<amanda>, method=PLAIN, rip=::ffff:xxx.xxx.xxx.xxx, lip=::ffff:192.168.1.2, TLS dovecot: Nov 14 17:00:50 Info: imap-login: Login: user=<ehmsen>, method=PLAIN, rip=::ffff:xxx.xxx.xxx.xxx, lip=::ffff:192.168.1.2, TLS dovecot: Nov 14 17:00:51 Info: imap-login: Login: user=<ehmsen>, method=PLAIN, rip=::ffff:xxx.xxx.xxx.xxx, lip=::ffff:192.168.1.2, TLS dovecot: Nov 14 17:04:58 Info: imap-login: Login: user=<ehmsen>, method=PLAIN, rip=::ffff:xxx.xxx.xxx.xxx, lip=::ffff:192.168.1.2, TLS dovecot: Nov 14 17:30:40 Info: IMAP(amanda): Disconnected for inactivity dovecot: Nov 14 17:43:29 Info: IMAP(amanda): Disconnected for inactivity Is there something I can do about this problem? Is the IDLE implementation in the 1.1 branch different from the implementation in the 1.0 branch of dovecot? Or can I debug this issue further? I guess these things are standardized, but it seems hard for Apple to follow a standard :-) Thanks in advance, Martin R. Ehmsen

[Dovecot] dovecot.index mtime
by Matt 15 Nov '07

15 Nov '07

Is there anyway I can get Dovecot to update mtime on dovecot.index everytime a user successfully checks there email? Or perhaps there is a better way to do what I want here. I am working on a script that I want to check when the last time a user checked there email account. If a user has not checked it in say 6 months I want to automatically suspend the account through the MTA. If they start checking it again I also want to automatically reinstate it. What I thought was a good way was to look at the mtime on dovecot.index but a user can be checking there email daily but if they do not receive a new message in say 6 months the mtime will date back to 6 months still. Ran into this with an email address used by a fax machine. So is there a better way with dovecot to determine this? I am using dovecot-1.0.rc29 right now. Matt

[Dovecot] New full text search indexer
by Timo Sirainen 14 Nov '07

14 Nov '07

As described earlier (http://dovecot.org/list/dovecot/2006-December/018055.html) Dovecot nowadays has full text search indexing support in CVS HEAD. Currently there are two backends: Lucene and Squat. Lucene's problem is that standard IMAP SEARCH command can't be used with it without breaking IMAP RFC. So Lucene can be used only with non-standard X-BODY-FAST and X-TEXT-FAST search commands. Squat's code then is quite complex and it's pretty slow. It works with 4 character blocks, so it can answer: - Search string < 4 characters: Can't answer anything - Search string = 4 characters: Definite yes/no - Search string > 4 characters: Probable yes / definite no Since search strings are usually more than 4 characters, Dovecot uses the index only to filter out messages which definitely won't match and then does regular searching for the non-filtered messages. It works ok, but it could work better. The Squat indexes take maybe 30-50% of the mailbox's size. Most of the space goes to UID lists (list of messages matching each 4 character block). For example one UID list could be "2,4-10,20-30". This is already stored in a compressed format by storing the UID numbers relative to previous UID, which allows storing them usually with a single byte per UID, even if the UIDs are large. So, this morning I had an idea how this could maybe be improved with two changes: 1. Don't use 4 character blocks. Instead allow variable sized paths, and keep track of the UIDs for each node in the path. So for example adding "abc" to UID 1 will place the UID 1 to node "a", "ab" and "abc". 2. Use UIDs relative to parent's UIDs. For example if node "a" has UIDs 1,3,5 and "ab" is added for UID 5, the UID is changed to 2 (3th in 1,3,5 list - 1). This can help the compression a lot. The best case scenario for the above example is if "ab" contains also 1,3,5 UIDs. Then it can be written with a single 0-2 range. With these changes, the indexer can be configured to perform in different ways. Text can be indexed in two ways: full words, and substrings within those words (as required by IMAP). I think a useful combination of these would be to index all 4 character substrings and all full words up to 10 characters or so. This kind of an index can answer: - Search string <= 4 characters: Definite yes/no - For X-BODY-FAST / X-TEXT-FAST: - Search string 5-10 characters: Definite yes/no - Search string 11+ characters: Probable yes / definite no - For standard IMAP SEARCH: - Search string 5-10 characters: Definite yes if message contains the key as non-substring, otherwise same as below. This helps only if user does a search that matches a lot of messages. - Search string 11+ characters: Probable yes / definite no UTF-8 text is indexed as bytes, but the path depth can be counted as characters instead of as bytes. I've a test program finished, and unless there are some bugs left I think it shows that this can work pretty well: Squat-like 4 byte substrings (but can answer 1-3 char queries also): Message count: 7495 Index time: 4.19 CPU seconds (7.39MB/CPUs) Node memory: 3014072 bytes (2943 kB) in 90550 nodes UID memory: 8277212 bytes (8083 kB) in 352778 lists Total: 11291284 / 32474899 bytes = 34.77% Indexing the same mailbox file with squat-test gives: - Index time: 9.55 CPU seconds, 9.63 real seconds (3.24MB/CPUs) - 4145192 bytes in 102208 nodes (12.76%) - 7286058 bytes in 305501 uid_lists (22.44%) - 11431250 bytes total of 32474899 (35.20%) So the new indexer is over twice as fast and uses slightly less space. Indexing 4 char substrings and words up to 10 chars: Index time: 5.13 CPU seconds (6.04MB/CPUs) Node memory: 6002804 bytes (5862 kB) in 615501 nodes UID memory: 9044610 bytes (8832 kB) in 519488 lists Total: 15047414 / 32474899 bytes = 46.34% So it takes somewhat more space, but definitely less than having both Squat + Lucene. No substring indexing, words up to 10 chars (Lucene replacement): Index time: 1.39 CPU seconds (22.28MB/CPUs) Node memory: 3297663 bytes (3220 kB) in 548540 nodes UID memory: 1803735 bytes (1761 kB) in 213554 lists Total: 5101398 / 32474899 bytes = 15.71% Is there a need for Lucene anymore with this kind of a speed and disk space usage? :) The above tests are run with everything being indexed except space and control chars (ie. practically space + tab). If only alphanumeric characters are indexed, the total lines are (in same order as above): Total: 7048664 / 32474899 bytes = 21.70% (-13.07%) Total: 9610543 / 32474899 bytes = 29.59% (-16.75%) Total: 3963335 / 32474899 bytes = 12.20% (-3.51%) There are probably still a few optimizations that can be done to get the disk space usage even lower. I did spent quite a lot of time making it use less CPU though. Even tried a bit different coding style variations in the critical functions to get gcc to create faster code.. One interesting thing I noticed was that binary searching a character from a char array was slower than just sequentially going through the characters. I tried adding checks to do it only if the array was big, but it was always slower. Maybe something to do with CPU cache. If you want to try yourself, the test program is in http://dovecot.org/tmp/new-indexer.c

[Dovecot] Using Dovecot as Asterisk PBX voicemail server
by Kenneth Porter 14 Nov '07

14 Nov '07

I'm reading the Asterisk book, 2nd edition, and it describes how one can set up voicemail to be delivered by IMAP to a voicemail folder. Asterisk can monitor flags on the folder so that the "message available" light on one's phone tracks the state of the "read" flag in the folder. One can either dial in for one's voicemail or listen to it from one's favorite IMAP client. (Dovecot is mentioned in the book.) I'm wondering how one would set up auth for this? Asterisk needs to log in to the account to deliver the voicemail and to check its state, but I wouldn't want to put everyone's mail password in plaintext in Asterisk's voicemail.conf file. Would I set up a separate IMAP account for each user to hold their voicemail, and use simple passwords (such as the PIN they use for phone access to voicemail) in the Asterisk config? Or is there a way to set up Dovecot to allow a second user to login to a specific IMAP folder in all accounts, in the same way the local delivery agent has write access to all users' mailbox? Google's page for the book: <http://books.google.com/books?id=vtQxJ3oSm64C&dq=asterisk+book> Dovecot mentions: <http://books.google.com/books?id=vtQxJ3oSm64C&dq=asterisk+book&q=dovecot#se…>

Hi list, Here is thing im trying to accomplish. I would like to setup public folders which resposible for delivering mails for some speical addresses like info(a)example.com. And it will be perfect if "seen" status for this folder will be saved per user. I mean if one user read message and set it as read other user should see it still as unread. As I far i know there some limitation in 1.0 tree but not in lates 1.1. My question is can I do such setup with dovecot+postfix. Im really appreciate for simple examples how can i accomplish this kind setup if it possible :)

http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta8.tar.gz http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta8.tar.gz.sig Changes since beta7: - Added a new "raw" mail storage backend which allows opening files/streams as single mail mailboxes. deliver uses this now instead of opening the incoming mail as a mbox. So deliver should be now faster and it doesn't anymore remove Dovecot's private mbox headers if you're not using mbox. - Cache file tracks message expunges again - All kinds of other fixes - Some optimizations I think we're getting closer to v1.1 RCs.

[Dovecot] Missing deliver
by Sean Smitz 13 Nov '07

13 Nov '07

I've installed Red Hat Enterprise Linux 5 on a new server. I'm configuring sendmail and dovecot; however, /usr/local/libexec/dovecot was not created when I installed the dovecot rpm (rpm -Uvh dovecot-1.0-1.2.rc15.el5.x86_64.rpm). The problem is I can't find the deliver executable which is supposed to be in this directory. Any help would be appreciated.

[Dovecot] login_process_size too small on x86_64 Fedora/RHEL
by Tomas Janousek 12 Nov '07

12 Nov '07

Hello, as described in [253363], login_process_size of 32M is not enough on 64-bit versions of Fedora and RHEL (and possibly other distributions as well). [253363] https://bugzilla.redhat.com/show_bug.cgi?id=253363 As I understand it, there's an intersegment gap between read-only/executable and writable segments of shared libs. That's probably a security feature or something. I found a similar issue here[1], if anyone wants a comment from someone who understands it. [1] http://gcc.gnu.org/ml/libstdc++/2006-12/msg00033.html Shall we just increase login_process_size or make it arch-dependent or something? Regards, -- Tomas Janousek, SW Engineer, Red Hat, Inc.

[Dovecot] Secure authentication?
by Bjørn T Johansen 12 Nov '07

12 Nov '07

I have enabled SSL support for my dovecot installation but if I enable secure authentication in my MUA, I get an error from dovecot telling me that this is not supported.. Is this because dovecot does not support this or am I missing some config?

[Dovecot] v2.0 / Master/config rewrite
by Timo Sirainen 12 Nov '07

12 Nov '07

If anyone's interested, I updated my master/config rewrite to latest Dovecot v1.1 tree and added it to hg: http://hg.dovecot.org/dovecot-master-rewrite/ It probably doesn't work, but with the exception of plugins it compiles anyway. :) I'm thinking that maybe after v1.1.0 I could continue with the rewrite and create v2.0 after all instead of v1.2. Just look at how much cleaner deliver.c is :) http://hg.dovecot.org/dovecot-master-rewrite/file/59ebbfcf21cb/src/deliver/… vs http://hg.dovecot.org/dovecot/file/eb4f1fbeecda/src/deliver/deliver.c Another thing with v2.0 I was thinking about was to change index file formats to be more efficient.

[Dovecot] some mail accesses in dovecot 1.1 stall for a bit (in progress)
by Adam McDougall 11 Nov '07

11 Nov '07

I noticed this in an earlier beta and took a note, and I still see it sometimes in 1.1b4, but it is only occasional so I have not tracked down yet what dovecot is doing. Just a FYI for the list incase others see it and to say that its an issue I tend to track down that I did not see in 1.0, and its been low on my list until now. Sometimes when I login to dovecot and read a message from an imap maildir folder, the message contents do not load for at least 10 seconds, sometimes closer to a minute, but after that first message loads, the rest seem fine in that mailbox. The time seems to vary some, usually longer rather than shorter.

Do you need a gdb backtrace for this one? I'm not sure why all of a sudden this started happening, its probably due to me adding a folder somewhere? not sure. It happened when I went to open my folder subscriptions in thunderbird. It was taking longer than usual (call this phase 1) and I noticed this in the logs: (cant remember if this was phase 1 or 2 but the error is probably the same) Nov 11 00:38:38 boomhauer dovecot: imap-login: Login: user=<mcdouga9>, method=PLAIN, rip=208.53.102.126, lip=35.9.37.190, TLS Nov 11 00:38:39 boomhauer dovecot: IMAP(mcdouga9): fchown(/egr/mail/shared/decs/temp.boomhauer.3050.af3db3ac545170a7) failed: Operation not permitted Nov 11 00:38:44 boomhauer dovecot: IMAP(mcdouga9): file mailbox-list-maildir.c: line 186 (maildir_list_get_path): assertion failed: (mailbox_list_is_valid_existing_name(_list, name)) Nov 11 00:38:44 boomhauer dovecot: child 3050 (imap) killed with signal 6 Nov 11 00:38:45 boomhauer dovecot: imap-login: Login: user=<mcdouga9>, method=PLAIN, rip=208.53.102.126, lip=35.9.37.190, TLS Nov 11 00:38:45 boomhauer dovecot: IMAP(mcdouga9): fchown(/egr/mail/shared/decs/temp.boomhauer.3052.5538be060c2f9c7d) failed: Operation not permitted Nov 11 00:38:46 boomhauer dovecot: IMAP(mcdouga9): file mailbox-list-maildir.c: line 186 (maildir_list_get_path): assertion failed: (mailbox_list_is_valid_existing_name(_list, name)) Nov 11 00:38:46 boomhauer dovecot: child 3052 (imap) killed with signal 6 When I cancelled the subscription window, "phase 2" is the same thing but happening more rapidly.

[Dovecot] Outlook can't see namespace folders
by James 10 Nov '07

10 Nov '07

Hi guys i understand that you can't subscribe to the Prefix names of namespace folders right now with dovecot. But for instance if i user outlook express and it can't see the prefix name then it can't see the subfolders of that "prefix folder" either. So even though it can detect and see the subfolders it won't display them cause it can't see the "parent" Is there any fix for this? it's also kind of annoying in thunderbird but at least you can still see the subfolders. TIA James Here's my config # /etc/dovecot/dovecot.conf protocols = imap imaps pop3 pop3s log_timestamp = "%Y-%m-%d %H:%M:%S " first_valid_uid = 100 login_user=vmail mail_extra_groups = mail mail_debug = yes pop3_uidl_format = %08Xu%08Xv mail_location = maildir:/home/vmail/domains/%n/Maildir #default_mail_env = maildir:/home/vmail/domains/%n/Maildir auth default { mechanisms = plain passdb ldap { args = /etc/dovecot/dovecot-ldap.conf } userdb ldap { args = /etc/dovecot/dovecot-ldap.conf } } # maildir namespace private { separator = / prefix = location = maildir:/home/vmail/domains/%n/Maildir inbox = yes hidden = no } # mbox namespace private { separator = / prefix = "Mbox/" location = mbox:/home/vmail/domains/%n/Mbox inbox = no hidden = no } #public spam folder namespace public { separator = / prefix = /Spam/ location = maildir:/home/vmail/domains/Spam/Maildir/ hidden = no } ssl_disable = no ssl_cert_file = /etc/ssl/certs/dovecot.pem ssl_key_file = /etc/ssl/private/dovecot.pem ssl_verify_client_cert = no ssl_cipher_list = ALL:!LOW:HIGH:MEDIUM:+SSLv2:RSA

[Dovecot] Request for variable unique to each server?
by Adam McDougall 10 Nov '07

10 Nov '07

I've been looking for a variable I can use in my dovecot.conf within the INDEX= setting so I can have one index dir per imap server on NFS. I've been looking at http://wiki.dovecot.org/Variables but no variable seems to contain something like server hostname, and I've been hunting for the variable expansion code in dovecot but haven't been able to find it. %l (local IP) won't help me because when using our load balancer, %l is the same IP on all of my servers. %r is close to useful but having a local webmail server on each server means I'd end up with 127.0.0.1 being shared (also I would end up with one directory per unique user/clientIP combo). Is there a variable that holds the server hostname or something else unique per server, or could one be added, or could someone point me at the code? Thanks.

[Dovecot] UTF-8 in dovecot-sieve ?
by Arthur Pétry 10 Nov '07

10 Nov '07

Hi, Reading http://tools.ietf.org/html/rfc3028#section-2.7.2 I thought that out-of-the-box dovecot can filter messages by matching header in UTF-8. But when I tested it, it failed : (I'm using 1.0.5 with sieve plugin) Here is my .dovecot.sieve file : ---------- require ["fileinto", "imapflags"]; if allof(header :contains "subject" "filtre") { addflag "test_1"; } if allof(header :contains "subject" "là") { addflag "test_2"; } if allof(header :comparator "i;ascii-casemap" :contains "subject" "hé") { addflag "test_3"; } ---------- Only the first of the three rules do work. When I try to match a subject string with accent encoded in ISO-8859 like "hélà" : "=?ISO-8859-1?Q?h=E9l=E0?=" there is no match Am I doing something wrong ?

[Dovecot] 1.0beta7 still has SEARCH TEXT not search the FROM

I just tried out 1.0beta7 and erased all my indexes and with fts and fts_squat enabled, and when I SEARCH TEXT in Dovecot, it does *not* find messages where the thing I SEARCH for appear only in the From: header.

[Dovecot] Dovecot I/O scheduling (all versions)
by mikkel＠euro123.dk 08 Nov '07

08 Nov '07

I have experienced this on all versions of Dovecot that Ive used (1.0 - 1.1b6) using IMAP (its difficult to test if its also there with POP3). What I see is that if there is a peak in disk usage at the time of a specific request that requests stalls. The saturation of disk I/O is momentary but when its done (maybe after one or two seconds) Dovecot still waits for its I/O operation instead of continuing as soon as resources are available. Now, I would expect Dovecot to only wait until there are resources available and not stall for at long time (sometimes it stalls for like 10 seconds, and sometimes completely). This could be OS specific (Im using ZFS and Solaris 10 on Sparc) but it may also be due to the way dovecot is programmed. Theres always plenty of RAM and CPU available so thats not whats causing troubles. Is anyone else familiar with this issue? Regards, Mikkel

http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta7.tar.gz http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta7.tar.gz.sig Changes since beta6: - Beginnings of unit tests, as I mentioned in a previous mail - Message parsing fixes - Cache file handling fixes Known bugs: - Cache file doesn't keep track of how much it contains deleted data, which means it could grow infinitely. This worked at some point, so I'm not sure what I did to break it. I'll figure it out later. - Apparently for some use cases v1.1 is still slower (about 2x) than v1.0. Probably more or less specific to NFS + mmap_disable=yes.

Unit testing is good, even though it's boring and not very glamorous. I wonder if you have seen or considered libtap, possibly as an optional dependency for those who care about running the tests? http://jc.ngo.org.uk/trac-bin/trac.cgi/wiki/LibTap It looks like it could almost drop in, in place of some of your existing test helpers. It is also compatible with a variety of end user test tools. However, I could see hesitation in adding external dependencies where they aren't really necessary. If you had TAP compatibility through libtap or other means, I could easily drop dovecot into our existing suite of nightly smoke tests on FreeBSD. > I'm probably going to be pretty lazy at adding more of those tests, so > if you've ever wanted to get your own code to Dovecot, now would be a > great time to do it! :) With a 5 month old and a 4 year old on hand, "copious free time" isn't my strong point, but I'll at least attempt to provide tests with any future bug reports.

[Dovecot] How to set multi backends (with same type)
by maximatt 07 Nov '07

07 Nov '07

hi..... i don't know if its posible. i have two ldap directories, and i want use them to use as my dovecot users backend... so i have two configurations files... "dovecot-ldap1.conf" and " dovecot-ldap2.conf" and i try setting like: Test 1: (simil postfix ) :D This dont work auth default { : : passdb ldap { args= /etc/dovecot/etc/ldap/dovecot-ldap1.conf, /etc/dovecot/etc/ldap/dovecot-ldap2.conf } userdb ldap { args= /etc/dovecot/etc/ldap/dovecot-ldap1.conf, /etc/dovecot/etc/ldap/dovecot-ldap2.conf } } Test 2: This dont work auth default { : : passdb ldap { args= /etc/dovecot/etc/ldap/dovecot-ldap1.conf/etc/dovecot/etc/ldap/dovecot- ldap2.conf } userdb ldap { args= /etc/dovecot/etc/ldap/dovecot-ldap1.conf/etc/dovecot/etc/ldap/dovecot- ldap2.conf } } Test 3: (looking "passbd ldap" as a set) :) this work, but dovecot-ldap2.conf override dovecot-ldap1.conf (the set vision, none) auth default { : : passdb ldap { args= /etc/dovecot/etc/ldap/dovecot-ldap1.conf args= /etc/dovecot/etc/ldap/dovecot-ldap2.conf } userdb ldap { args= /etc/dovecot/etc/ldap/dovecot-ldap1.conf args= /etc/dovecot/etc/ldap/dovecot-ldap2.conf } } ¿How could i do this? :( Thanks in advance :) -- Salu2 ;)

[Dovecot] imaptest update
by Timo Sirainen 07 Nov '07

07 Nov '07

http://dovecot.org/tools/imaptest.c now keeps track of messages' metadata and complains if they change. It relies on Message-ID: header being unique in the source mailbox, otherwise it'll give bogus errors. I might fix that some day. I changed the code from using simple line-based parsing to Dovecot's imap-parser code. Unfortunately it looks like it's pretty slow. At least I'm pretty sure imaptest didn't take more than a few % of CPU before, while now it's showing 35% CPU usage.. I guess I'll have to profile it a bit to see what's eating the CPU. And yes, looks like it found a couple of bugs from Dovecot 1.1's MIME parsing (BODY/BODYSTRUCTURE replies change). That was actually why I wrote this code in the first place, I was trying to figure out how to reproduce a bug. I'm getting closer to my stress testing dream tool. :) http://mailman1.u.washington.edu/pipermail/imap-protocol/2007-March/000413.…

[Dovecot] Unit testing
by Timo Sirainen 07 Nov '07

07 Nov '07

I finally added beginnings of unit tests to Dovecot v1.1 code tree: http://hg.dovecot.org/dovecot/rev/4e4a5d6bb2cb There are currently just a couple of tests implemented in test-lib (lib/ functions) and test-mail (lib-mail/ functions). I'm probably going to be pretty lazy at adding more of those tests, so if you've ever wanted to get your own code to Dovecot, now would be a great time to do it! :)

[Dovecot] index corruption
by rosenfield＠users.sourceforge.net 07 Nov '07

07 Nov '07

Hi people Just switched to Dovecot yesterday, and I've already got about five reports of users with duplicate mail in their inbox :-/. Not as bad as lost email, mind you, but pretty annoying still. Checking the server log, it says: postfix/smtpd: disconnect from unknown deliver: msync() failed with index file maildir/dovecot.index: Input/output error unionfs: new lower inode mtime (bindex=0, name=maildir) dovecot: IMAP: msync() failed with index file maildir/dovecot.index: Input/output error IMAP: Disconnected: Internal error occurred. Refer to server log for more information. This is dovecot version 1.0.3, the log presented here relates to only one user; user name snipped for anonymity purposes. Afterwards things just get worse and worse with the affected user: dovecot: IMAP: msync() failed with index file maildir/dovecot.index: Input/output error dovecot: IMAP: msync() failed with index file maildir/dovecot.index: Input/output error dovecot: IMAP: msync() failed with index file maildir/dovecot.index: Input/output error deliver: msync() failed with index file maildir/dovecot.index: Input/output error dovecot: IMAP: msync() failed with index file maildir/dovecot.index: Input/output error dovecot: IMAP: msync() failed with index file maildir/dovecot.index: Input/output error dovecot: IMAP: msync() failed with index file maildir/dovecot.index: Input/output error dovecot: IMAP: msync() failed with index file maildir/dovecot.index: Input/output error dovecot: IMAP: msync() failed with index file maildir/dovecot.index: Input/output error dovecot: IMAP: Corrupted transaction log file maildir/.SPAM/dovecot.index.log: invalid new transaction log sequence (1 >= 1) dovecot: IMAP: fscking index file maildir/.SPAM/dovecot.index dovecot: IMAP: Transaction log file maildir/.SPAM/dovecot.index.log: marked corrupted dovecot: IMAP: Corrupted transaction log file maildir/.SPAM/dovecot.index.log: invalid new transaction log sequence (2 >= 2) dovecot: IMAP: fscking index file maildir/.SPAM/dovecot.index dovecot: IMAP: Corrupted transaction log file maildir/.Junk/dovecot.index.log: invalid new transaction log sequence (1 >= 1) dovecot: IMAP: fscking index file maildir/.Junk/dovecot.index dovecot: IMAP: Transaction log file maildir/.Junk/dovecot.index.log: marked corrupted dovecot: IMAP: Corrupted transaction log file maildir/.Junk/dovecot.index.log: invalid new transaction log sequence (2 >= 2) dovecot: IMAP: fscking index file maildir/.Junk/dovecot.index deliver: msync() failed with index file maildir/dovecot.index: Input/output error dovecot: IMAP: msync() failed with index file maildir/dovecot.index: Input/output error dovecot: IMAP: msync() failed with index file maildir/dovecot.index: Input/output error dovecot: IMAP: msync() failed with index file maildir/dovecot.index: Input/output error dovecot: IMAP: msync() failed with index file maildir/dovecot.index: Input/output error deliver: msync() failed with index file maildir/dovecot.index: Input/output error dovecot: IMAP: msync() failed with index file maildir/dovecot.index: Input/output error dovecot: IMAP: msync() failed with index file maildir/dovecot.index: Input/output error dovecot: IMAP: msync() failed with index file maildir/dovecot.index: Input/output error What could be the problem?

[Dovecot] IMAP - Empty attachments error
by Tomáš Klandra 06 Nov '07

06 Nov '07

Hallo, I have one problem with the following configuration: - server: debian, dovecot used as an IMAP server, version 0.99.14. - stations: windows 2k/XP, mailer seamonky 1.1.4 Sometimes (let's say once in 20 attemptes) when saving attachments, they are empty (zero size files). Simple re-saving them helps. I was looking on mozilla forums if it's not a bug in SeaMonkey, which looked more likely to me, but didn't find anything, so I got the idea it could be a bug in dovecot. If someone saw this as well or have any ideas, I would really appreciate any help about it, as the error is really annoying. Thank you, Tom

[Dovecot] User keywords limit to 26
by Arthur Pétry 06 Nov '07

06 Nov '07

Hi, I'm planning to use dovecot 1.0.5 for a webmail using a lot of user- defined tags. Recently, I just saw the limit of 26 of them when messages are stored in maildir format. This is an important issue for me, since I didn't find how to remove a flag from the dovecot-keywords database. Is there any plan to get rid of the keywords limit ? Or perhaps the new dbox storage format can fix that ? By the way, the comportement of Dovecot when we try to add a new flag while the limit is exceeded is strange : (C: is client and S: Dovecot) The store of the flags is ok : C: RUBY0094 UID STORE 89 +FLAGS (test_0 test_1 test_2 test_3 test_4 test_5 test_6 test_7 test_8 test_9 test_10 test_11 test_12 test_13 test_14 test_15 test_16 test_17 test_18 test_19 test_20 test_21 test_22 test_23 test_24 test_25 test_26) S: * 81 FETCH (UID 89 FLAGS (\Seen test_1 test_2 test_3 test_4 test_5 test_6 test_7 test_8 test_9 test_10 test_11 test_12 test_13 test_14 test_15 test_16 test_17 test_18 test_19 test_20 test_21 test_22 test_23 test_24 test_25 test_26 test_0)) S: RUBY0094 OK Store completed. And then when we fetch them, dovecot reply 2 times. The first time with all the flags, and the second time with only the 26 flags stored in maildir. (I suppose Dovecot try to sync the flags when we fetch it) : C: RUBY0095 UID FETCH 89 FLAGS S: * 81 FETCH (FLAGS (\Seen test_1 test_2 test_3 test_4 test_5 test_6 test_7 test_8 test_9 test_10 test_11 test_12 test_13 test_14 test_15 test_16 test_17 test_18 test_19 test_20 test_21 test_22 test_23 test_24 test_25 test_26 test_0) UID 89) S: * 81 FETCH (FLAGS (\Seen test_1 test_2 test_3 test_4 test_5 test_6 test_7 test_8 test_9 test_10 test_11 test_12 test_13 test_14 test_15 test_16 test_17 test_18 test_19 test_20 test_21 test_22 test_23 test_24 test_25 test_0)) S: RUBY0095 OK Fetch completed.

[Dovecot] Sent vs Sent Items
by Ed W 06 Nov '07

06 Nov '07

Religious wars about which is "best" aside - some mail clients seem to default to using "Sent Items" folder for saving sent mail, and others (many) default to "Sent". Seems that in the interests of compatibility and "doing the right thing" (tm) that a symlink from one folder to the other name would ensure that either default would give the same result (in a mixed client setup)? However, I wonder if someone has already written a plugin to do something simple like this? More generally I guess it's folder aliasing, so that Sent == Sent Items and perhaps there are also synonyms for Drafts/Templates? Anyone got any thoughts on this simple idea? (The prob with sym links is a) creating them at mailbox setup time and b) what happens when someone tries to delete the folder...) Cheers Ed W

[Dovecot] MySQL-SSL
by xyon 06 Nov '07

06 Nov '07

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello all, I've been running dovecot authenticating against a local MySQL database, but it has come time to implement it with a remote database. Instead of using stunnel, I'd rather take advantage of MySQL's native SSL support. I didn't know if this was possible with dovecot, and if it was, what config changes I might need to get it going. I found the below page/patch from some time ago and tried to use the ssl_key and ssl_cert directives in /etc/dovecot-sql.conf, but it didn't seem to recognize them (perhaps I need to compile mysql-ssl support into dovecot manually?): http://www.dovecot.org/list/dovecot-cvs/2004-July/003003.html Also, I noticed a need for ssl_ca and ssl_ca_path but am unfamiliar with how to generate what's needed if these options are required. FYI, dovecot 1.0.7 is running on CentOS 4.5, using rpm from ATrpms: http://dl.atrpms.net/el4-i386/atrpms/stable/dovecot-1.0.7-0_63.el4.i386.rpm Thanks for any advice or documentation pointers you can provide.

[Dovecot] truncated messages / attachments
by Markus Stumpf 05 Nov '07

05 Nov '07

I am currently running dovecot-1.1.beta6 (at least beta5 also had the problem) Retrieving some messages via IMAP gets them truncated and it also happens with retrieving attachments (message is HTML part of multipart-alternative, attachments are at least some PDF files). A user reported she is rather sure one of the messages was ok, before moving it to some other folder. In the filesystem the messages are there in full length. It happens with Outlook as well as with Thunderbird. We're using Maildir. After upgrading from beta5 to beta6 I have removed all dovecot.index* files of a folder with a defect message. This didn't make a difference. (Thought it could be related to some indexing problem). Any one else seeing this? \Maex -- Markus Stumpf

[Dovecot] Couldn't init INBOX: Can't sync mailbox: Messages keep getting expunged
by Tom Sommer 05 Nov '07

05 Nov '07

After updating Dovecot, one of my servers keep spamming these errors in the log: dovecot: Nov 03 14:14:18 Error: POP3(foo(a)bar.com): Getting size of message UID=4402 failed dovecot: Nov 03 14:14:18 Error: POP3(foo(a)bar.com): Getting size of message UID=4402 failed dovecot: Nov 03 14:14:18 Error: POP3(foo(a)bar.com): Couldn't init INBOX: Can't sync mailbox: Messages keep getting expunged The funny thing is the mailbox is empty, there are no mails in the folder that should be needed to be parsed It was perfectly fine before I updated, and the permissions on the folder is correct. It only affects some mailboxes as well. Any ideas? // Tom

I guess the reason is that ZFS can now make use if it's caching capabilities. Delivers activity is completely random since it's impossible to load balance a connection based on the e-mail recipient, since only the ip is known at the load balancing point. Therefore I have fsync_disable=no for deliver. It's easy to force the clients using imap/pop3 to the same server since it can be based on the ip only. Therefore I have fsync_disable=yes for imap/pop3. This changed everything. Now there's a real performance gain upgrading from 1.0.x to 1.1.x. About two or three times less disk activity overall (reads were already improved) for both reads and writes. Thats pretty neat!

[Dovecot] Dovecot write activity (mostly 1.1.x)
by mikkel＠euro123.dk 04 Nov '07

04 Nov '07

Im experiencing write activity thats somewhat different from my previous qmail/courier-imap/Maildir setup. This more outspoken in v.1.1.x than v1.0.x (Im using Maildir). Write activity is about half that of read activity when measuring throughput. But when measuring operations its about 5-7 times as high (measured with zpool iostat on ZFS). I think this might be due to the many small updates to index and cache files. Anyway since writing is much more demanding to the disk than reads dovecots ends up being slower (only a little though) than my old qmail/courier-imap/Maildir was. And the old setup didnt even benefit from indexes like Dovecot does. (What I mean saying slower is that it can service fewer users before it hits the wall). Of course theres also lots of benefits using Dovecot. Im just wondering whether this was a thing that should be focused on for later versions (maybe writes could be grouped together or something like that). Dovecot is very cheap on the CPU side so the only real limit in terms of scalability is the storage. Regards, Mikkel

[Dovecot] IMAP vs system username logging with checkpassword auth
by dale gallagher 03 Nov '07

03 Nov '07

Hi After upgrading to dovecot 1.0.7 I noticed that the actual username is no longer logged, but rather the system user (in my case 'vmail') under which my virtual set-up runs. Now I'm unable to see which virtual users log in. Any pointers on how to configure dovecot to log the actual username given during the IMAP dialogue would be appreciated. My dovecot.conf includes the following: auth default { mechanisms = plain passdb checkpassword { args = /var/qmail/bin/qmail-vauth } userdb prefetch { } user = auth } An example logfile entry: 2007-11-03 15:41:56.027191500 dovecot: Info: imap-login: Login: user=<vmail>, method=PLAIN, rip=192.168.0.141, lip=192.168.0.10, TLS

[Dovecot] MANAGESIEVE patch v8 for dovecot 1.0.7
by Stephan Bosch 03 Nov '07

03 Nov '07

Hello dovecot users, I have updated the MANAGESIEVE patch to the latest stable version of dovecot (1.0.7). This new version also adds extra configuration settings to explicitly specify the location of the sieve storage and the active sieve script. Additionally, the README now more clearly explains the configuration of the daemon. It currently won't compile with 1.1 due to significant changes in the master code. However, because 1.1 now approaches a stable release, the next version is going to be updated to version 1.1. Change Log V8 ------------- + Fixed a few incompatibilities with 1.0.7 version. For instance, the "Logged in" message is now sent by the -login process and not by the managesieve daemon anymore. This caused a segfault every once in a while. + Probably fixed the settings problem reported by Steffen Kaiser regarding login_dir. 'dovecot -n' now reports correct results, but testing will show whether the whole problem is solved. + The managesieve daemon now accepts the sieve_storage and sieve configuration settings, so it is now possible to explicitly configure the location of the sieve storage and the active script respectively. The daemon still falls back to using the mail_location (MAIL) settings if nothing else is specified. + The cyrus timsieved does not use the + character in string literals and many clients have adopted to this behaviour. The latest managesieve (08) advises to accept a missing + from clients. The server should not send any + characters as well. This behavior is now implemented on the server. + Cleaned up sieve-storage.c: split up the sieve_storage_create function in various sub-functions for obtaining the various paths and directories. + Forced manual intervention if rescueing a non-symlink file at the active script path fails somehow. Previously, this presented the admin with a log message that it had just eaten the script, which is not very nice. + Restructured the README.managesieve file and added some more explanation with regard to the configuration of the daemon. This patch still includes (yet another) instance of the CMU Sieve source, as explained in one of my previous e-mails (http://dovecot.org/list/dovecot/2006-July/015016.html) The patch can be downloaded at: http://sinas.rename-it.nl/~sirius/dovecot-1.0.7-MANAGESIEVE-v8.diff.gz The README.managesieve is located in the root of the dovecot source tree after applying the patch. Have fun testing the patch. Don't hesitate to notify me when there are problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl IRC: Freenode, #dovecot, S[r]us

[Dovecot] Listening only on localhost

Hi! I've got dovecot 1.0.rc15. I want dovecot to listen only on localhost for imap, and on any interfaces for imaps. So I put the following into my config: protocol imap { listen = 127.0.0.1:143 ssl_listen = *:10993 .. } dovecot -n correctly reports: listen: 127.0.0.1:143 ssl_listen: *:10993 But I can still do a 'telnet MY_HOST 143' from the outside, and 'netstat -pltn | grep dovecot' reports: [ip changed ;)] tcp 0 0 77.my.ip.253:10993 0.0.0.0:* LISTEN 4847/dovecot tcp 0 0 77.my.ip.253:143 0.0.0.0:* LISTEN 4847/dovecot Am I doing something wrong?

[Dovecot] caching custom headers (via plugins)
by Paolo 02 Nov '07

02 Nov '07

hi, currently dovecot caches on disk some most common headers. Is it possible to tweak such headers list via plugins, eg to cache custom X-* headers, or do I need to hack the actual index/cache src? if so, which are the .c/.h files to touch? thanks -- paolo GPG/PGP id:0x1D5A11A4 - 04FC 8EB9 51A1 5158 1425 BC12 EA57 3382 1D5A 11A4

http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta5.tar.gz http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta5.tar.gz.sig APPEND should be working now. Also lots of fixes to handling namespace prefixes and namespaces where virtual separator differs from real separator. zlib plugin now supports opening compressed maildir files. This is done for files that have Z flag. SORT still assert-crashes sometimes. Would be great if someone could show me how to reproduce it. SEARCH TEXT or Squat indexes apparently still have some problems, but I couldn't reproduce them (http://dovecot.org/list/dovecot/2007-October/026254.html)

[Dovecot] Bug within Authentication Caching
by Matthias Waffenschmidt 02 Nov '07

02 Nov '07

Hello, there seems to be a bug in the authentication caching code when using it in combination with username_translation (using the current version 1.0.7 on FreeBSD 6). I've set username_translation to +@:@ to allow usernames of the form test+dom.ain or test:dom.ain (historical reasons force us....). If someone has a successful login using the username test(a)dom.ain, the subsequent authentication information is read from the cache, no matter which of the 3 possible usernames the client uses the next time. But if someone has a successful login using the username test+dom.ain, the following data has or has not been found in the cache: test+dom.ain: miss test(a)dom.ain: miss test:dom.ain: hit If the first username is test:dom.ain the behaviour is the following: test:dom.ain: miss test(a)dom.ain: miss test+dom.ain: hit I've added the information if the username changes for better debugging possibilities. In practice the username is of course always the same. The complete authentication part of the tested config: auth default: cache_size: 10000 username_chars: abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@:+ username_translation: +@:@ verbose: yes debug: yes debug_passwords: yes passdb: driver: passwd-file args: /var/pop/%d/Accounts.passwd userdb: driver: static args: uid=70 gid=70 home=/var/emtpy It looks as if Dovecot does some wrong username translations before inserting/lookup up the data in the cache. BTW: a SIGUSR2 signal to the dovecot-auth process does not give any information as suggested in http://wiki.dovecot.org/Authentication/Caching. Please do not only answer to the list as I am not subscribed. Thanks. -- Gruss / Best regards | LF.net GmbH | fon +49 711 90074-411 Matthias Waffenschmidt | Ruppmannstr. 27 | fax +49 711 90074-33 mw(a)LF.net | D-70565 Stuttgart | http://www.lf.net

[Dovecot] dovecot + LDAP + SASL?
by hadmut＠danisch.de 02 Nov '07

02 Nov '07

Hi, I would like to setup an IMAP server with SASL and LDAP support. As far as I can see dovecot supports SASL and LDAP, but not the way I need it. If I understand dovecot correctly, it has it's own set of SASL mechnisms and uses the LDAP server just to store the plaintext password. In case of authentication dovecot fetches the plaintext password from LDAP and then performs the SASL steps internally. I need to support proprietary SASL mechanisms built into an LDAP server, which are not based on just a single password. So is there a way to configure dovecot to just pass SASL through to LDAP, allowing the IMAP client to talk SASL with the LDAP server through dovecot? regards Hadmut

[Dovecot] Successful experience with auth_winbind module
by Dmitry Butskoy 02 Nov '07

02 Nov '07

Hi, Recently the support of Samba's ntlm_auth helper was added to dovecot-auth (mech-winbind.c etc.). It is alrready in 1.1, the patch for 1.0 is here: http://dovecot.org/patches/1.0/dovecot-1.0.3-winbind.patch . It allows auth against NT or AD domain. I would like to infrom all that we successfully use this new feature during 2 month and ~300 users 24x7 (an energy power company). No any failures at all! This feature allows to specify "SPA" (Secure Password Authentication) option in OE, and to avoid explicit user passwords in mail accounts. Some random notes: - In the mixed environment (both plain and ntlm methods in use), you have to specify: mechanisms = plain ntlm login i.e. "ntlm" before "login". When sending mails, OE just catch first seen and try to use it, even if you specify to use SPA in the mail account preferences. - It seems that MS Outlook requires the specifying of password even when SPA is in effect - When OE has several identities, and one of the identities has SPA for SMTP set (outgoing mail), it wins over all another identities. - "The Bat" mailer supports NTLM for reading, not sending, and requires password too. Regards, Dmitry Bustkoy http://www.fedoraproject.org/wiki/DmitryButskoy P.S. We use NTLM only, GSS-SPNEGO still not tested.

Theirs is a proprietary system which from what I've read, seems to use SMS in combination with IMAP. Wacky. (If you aren't talking about iPhone compatibility, I'm less knowledgeable, but dovecot does support IDLE-style "imap push" style notification.) Alan Ferrency

[Dovecot] mail_location and master_user rel 1.0.x

login me(a)mymail.net*theboss thebossespwd this is a great piece of software, but it has some frustrating issues. i have included my two configurations below, just FYI. the one (older) system is 1.0rc7 on mandriva 2007.0 and postfix 2.3.3 and amavisd and spamassassin and using a maildir configuration the newer system is 1.0.5 (soon to be 7) on mandriva 2008.0 and postfix 2.4.5 amavisd and spamassassin and using a maildir configuration first, i followed the instructions in this document http://wiki.dovecot.org/Authentication/MasterUsers to the letter and it works for neither the old server nor the new. specifically i was using the first example configuration. all i ever got was: Connected to mail.mailserver.com Escape character is '^]'. * OK [CAPABILITY IMAP4rev1 SASL-IR SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN NAMESPACE LOGIN-REFERRALS STARTTLS AUTH=LOGIN AUTH=PLAIN AUTH=DIGEST-MD5] Dovecot ready. login him(a)mailserver.com*theboss thebossespwd login BAD Error in IMAP command received by server. and the auth_debug information was completely useless. if someone goes to the trouble of writing great examples they really should test to make sure they actually work. secondly: this configuration on the old server (1.0rc7) works fine: ##

[Dovecot] receive date wrong in outlook
by Farkas Levente 01 Nov '07

01 Nov '07

hi, we migrate from exchange to dovecot. we do it with imapsync. first we try to do it with --syncinternaldates, but this fails on many messages with invalid date, so we drop this option. unfortunately after this those users who use outlook see the received date as the date we do the migration in stead of the real received date. other clients eg webmail, thunderbird etc sees the right date. so my question what can i do? it's a dovecot bug or outlook and if outlook's bug is there any workaround fro this? thanks in advance. -- Levente "Si vis pacem para bellum!"

I've tried with apacheds ldap server versions 1.0.2 and 1.5.0 command line search with parameters taken from dovecot.debug log gives me all needed attributes. Comments and help welcome.

[Dovecot] Sometimes Dovecot v1.0.3 does not accept new connections
by Steffen Kaiser 30 Oct '07

30 Oct '07

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, occasionally Dovecot stops to accept new connections. Already existing ones do function properly. Strace'ing dovecot-auth reveals that it is running and is authentificating users, the logfile logs new connections. However, lots of other connects just stall, before the IMAP server responds with the greeting. My user backend is a LDAP server. I've sniffed the interface, but I also don't see numerous connection attempts, so I suppose, that there is no DoS attack running. The logfile contains no warning or error except: dovecot: Oct 17 15:34:44 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:34:49 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:34:52 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:02 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:05 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:12 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:19 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:20 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:25 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:26 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:27 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:27 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:41 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:42 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:47 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:49 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:49 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:50 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:56 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:36:03 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 Does somebody has an idea, where to go to look into the issue?

[Dovecot] 1.1Beta5 Issue
by Jeff Grossman 30 Oct '07

30 Oct '07

I installed 1.1Beta 5 this weekend. I had no problems at all yesterday using Thunderbird. I started reading my mail with Squirrelmail this morning and everything was going pretty smooth. I tried to delete a daily e-mail I receive from careerbuilder.com and the IMAP process shot up to 99.9% and I was not able to do anything in Squirrelmail. I killed that process and tried it again just to be sure what it was. And it did it again. I can delete any other message with no problems, just that one causes me issues. I am not sure if Thunderbird is the same, I will have to wait until I get home tonight. If there is any troubleshooting you would like me to do, please let me know. Jeff

[Dovecot] time going back
by zbigniew szalbot 29 Oct '07

29 Oct '07

Hi all, Sorry if this is trivial. I am just concerned. In Poland we will be putting the clocks one hour behind (back) on Sunday. I once saw dovecot killing itself because I manually adjusted the clock in the past. Will it not happen in this case? Thanks for your ideas. Zbigniew Szalbot

[Dovecot] Static home while using LDAP
by David Bosque 29 Oct '07

29 Oct '07

Hello all, I've been googling for a workaround for this for nearly a week to no avail and I hope someone in the list can shed some light on it. I have downloaded and compiled dovecot 1.0.5 and applied the quota-warning to it. I have configured everything and it's working wonderfully, even the lda with the sieve plugin. This is my current relevant configuration: userdb static{ args = uid=501 gid=12 home=/var/mail/buzones/%d/%n allow_all_users=yes } passdb ldap { args = /etc/dovecot/dovecot-ldap.conf } However, I need to obtain some more data from LDAP, so I need to switch to an ldap userdb, but want to keep the home as it is in the static configuration and not having to store it in LDAP. Is it possible to use a fixed home (as in the static userdb) while using an ldap userdb? I am looking for something similar to user_global_uid and user_global_gid but for the "home". If not, is it possible to fix or append something to the values in the user_attrs (like the following)? user_attrs = [whatever_i_want_to_append]uid=home uidNumber=uid,gidNumber=gid Regards, David Bosque

http://dovecot.org/releases/1.0/dovecot-1.0.7.tar.gz http://dovecot.org/releases/1.0/dovecot-1.0.7.tar.gz.sig Almost missed this one. I had already fixed it in v1.1 tree, but forgot to fix in v1.0 tree. - deliver: v1.0.6's "From " line ignoring could have written to a bad location in stack, possibly causing problems.

[Dovecot] lost emails with version 1.0.6
by Nishant Limbachia 29 Oct '07

29 Oct '07

Hi list members, I am using dovecot on Slackware 12.0 with postfix 2.4.5. I just upgraded to version 1.0.6 from 1.0.5 and now I am not getting emails. I am using dovecot deliver with postfix. deliver log also says email put into appropriate inbox. Starting up dovecot doesn't show any error messages. I've looked at the release notes and couldn't find any changes that should affect the config file. Here's an excerpt from dovecot deliver's log for the last two emails I've lost after upgrade. ### deliver(raghu): Oct 28 19:34:52 Info: msgid=<200710281935.AA6815928(a)stuart.iit.edu>: saved mail to INBOX deliver(raghu): Oct 28 19:40:13 Info: msgid=<200710281940.AA82444392(a)stuart.iit.edu>: saved mail to INBOX ### Any ideas? ---- tuxrules.in(a)gmail.com

[Dovecot] do 1.1b4 assertion failed: (mailbox_list_is_valid_existing_name
by Adam McDougall 28 Oct '07

I think this is where I left off last weekend. Instead of this happening at the base of one of my shared mail namespaces, it happens when I try to select a top level folder inside the namespace, or try to directly select an entire path to a folder. This only happens when ACL is enabled. Let me know if I need to provide more. Thanks.

[Dovecot] fallback for proxy?
by Cor Bosman 28 Oct '07

28 Oct '07

Is it possible somehow to configure a fallback for a failed proxy? I am using sql based proxying through dovecot, but it would be nice if you can fallback to another host if the proxy destination server is down. High availability and all.. Regards, Cor

[Dovecot] More core dump stack traces
by Lloyd Parkes 28 Oct '07

28 Oct '07

Hi all, I found a whole bunch of core files from imap this evening, so here are the stack traces from each. Unlike my last message, I don't have debugging symbols for these, so there isn't any analysis I can easily do. There were several cores with the first stack trace and one with the second trace. The core dump for the second trace is the only one I noticed. I suspect that the first trace happens when the client host goes to sleep. If so, the situation needs to be handled more gracefully. I'm currently building a copy of imap with debugging symbols.

[Dovecot] Possible Caching Bug showing up as a MIME Boundary Issue
by Kevin A. McGrail 27 Oct '07

27 Oct '07

Possible Caching Bug showing up as a MIME Boundary Issue I'm using Dovecot version 1.0.0. I was using Dovecot version 1.0.0 beta3 or alpha4. I upgraded to Dovecot 1.0.0 to make sure that was not the issue. Over the past few weeks on a server running a stable dovecot, I have seem a few emails arriving where the MIME document structure dividers are visible. I've included a screenshot showing this. Using OE6 as client. Have tried adding oe6-fetch-no-newmail per clients wiki but this seems to stop the ability to login at all. I am using two different machines with Outlook Express to access the same email. The same problem will show up on both. Usually, if I delete the .imap cache for the folder, the email comes down correctly. My dovecot -n output is: # /etc/dovecot.conf listen: *:144 ssl_listen: *:994 ssl_cert_file: /usr/local/ssl/certs/stunnel.pem ssl_key_file: /usr/local/ssl/certs/stunnel.pem disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login max_mail_processes: 50 verbose_proctitle: yes default_mail_env: mbox:~/:INBOX=/var/spool/mail/%u mail_location: mbox:~/:INBOX=/var/spool/mail/%u imap_client_workarounds: outlook-idle delay-newmail auth default: passdb: driver: pam userdb: driver: passwd userdb: driver: prefetch The server is on a heavily modified RedHat 7.2 on x86 box with ext3 Thanks in Advance, KAM

[Dovecot] trouble deleting folders that only contain folders
by Ken A 27 Oct '07

27 Oct '07

Hi, I'm using dovecot 1.0.5 with mbox storage. Users can't delete folders that are created to 'only hold other folders'. I can create these folders with no problem. They are directories in the file system. Normal folders (which are mbox files) are deleted with no problem. I've tried with both squirrelmail and Thunderbird, and what happens when a delete is requested, is that all files within the folder's dir tree are deleted and the client is unsubscribed, but the directory tree remains. Any ideas? Thanks, Ken -- Ken Anderson Pacific.Net

[Dovecot] 1.1b3 and Maildir quota
by Rick Romero 27 Oct '07

27 Oct '07

I upgraded a 1.0 install to 1.1b3. Almost everything is working peachy-keen :) It seems faster to me, Offline Folders and 'new mail' options for Thunderbird are now working, and Mail.App doesn't seem to need the extra namespace. Unfortunately it doesn't seem to read my quotas any longer. I went through the docs, and I see the quota plugin has changed, but there doesn't seem to be a needed configuration change. Did I miss something? I used my same dovecot.conf as 1.0: I also wiped clean my /usr/local/lib/dovecot directory and reinstalled, just to be sure, but it still doesn't work :/ Is it because I use checkpassword for my auth? # 1.1.beta3: /usr/local/etc/dovecot.conf base_dir: /var/run/dovecot/ log_path: /var/log/dovecot/dovecot.log info_log_path: /var/log/dovecot/dovecot_info.log disable_plaintext_auth: no shutdown_clients: no login_dir: /var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login login_user: nobody login_process_per_connection: no login_greeting_capability: yes login_process_size: 64 login_processes_count: 15 login_max_processes_count: 512 verbose_proctitle: yes first_valid_uid: 89 mail_executable: /usr/local/libexec/dovecot/rawlog /usr/local/libexec/dovecot/imap mail_plugins: quota imap_quota imap_client_workarounds: delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep namespace: type: private separator: . prefix: INBOX. inbox: yes list: yes auth default: user: vpopmail passdb: driver: checkpassword args: /usr/local/vpopmail/bin/vchkpw userdb: driver: prefetch plugin: quota: maildir dell#

[Dovecot] quota problems - which Dovecot version ?
by Albert Schweizer 27 Oct '07

27 Oct '07

Hi, I've got a little problem with Dovecot IMAP. Everything works nice ( pam auth, ldap userdb, and so on ) BUT i need to uses quotas and it doesn't seem to work. I tried both ways : 1) user dovecot-ldap.conf with user_attrs, as it's shown on dovecot wiki ; 2) use the commandes "plugin {.........." in dovecot.conf But it didn't work. Strangely, when i try to use the PLUGIN command in dovecot.conf, the server crashes at start, "syntax error" in config.... I'm not sure if the quotas are supported in my Dovecot version : version : 0.99.14 release : 1.EL4 I'm using an old AlphaServer ( dec ) with Centos 4.2 installed, and it's a real mess to get yum updates. Building from sources neither worked.... Please help !!! Regards Y.V.

[Dovecot] Duplicate message
by Timothy Murphy 27 Oct '07

27 Oct '07

I'm running dovecot on my desktop and using kmail as a client on my laptop. I am very happy with this - I was previously running kmail under NFS, and this is infinitely better. There is one small issue, which is not very important. I get a small number of messages apparently duplicated. This doesn't really matter, as there is a facility Folder=>Remove Duplicate Messages under kmail, and this deals with the issue easily enough. I just wondered though why I get the duplicate messages, and if there is some simple way to avoid them?

[Dovecot] dovecot-auth: Too many open files
by Joe Allesi -X (joallesi - Coyote Creek Consulting at Cisco) 27 Oct '07

27 Oct '07

All, [version: dovecot-0.99.11-4.EL4.src.rpm] We recently experienced an issue that prevented all new IMAP logins from occurring. Although it appears that it was due to running out of available system file descriptors, I'm still not sure what the true root cause was as I can't replicate the same error in our test environment. The system file descriptor max was set at (per `cat /proc/sys/fs/file-nr`) 380081 , and we're averaging around 7,000 in use. It appears that the main issue was dovecot-auth, so does this appear to fall in line with the known PAM bug in this version? Auth config: auth_userdb = passwd auth_passdb = pam Checked maillogs (cleansed): Oct 16 11:48:05 host dovecot-auth: PAM: pipe() failed: Too many open files Oct 16 04:48:06 host imap-login: Disconnected [::ffff:<internal_IP>] Oct 16 11:48:11 host dovecot-auth: PAM: pipe() failed: Too many open files Oct 16 04:48:11 host imap-login: Aborted login [::ffff:<internal_IP>] Oct 16 04:48:11 host dovecot-auth: PAM unable to dlopen(/lib/security/pam_nologin.so) Oct 16 04:48:11 host dovecot-auth: PAM [dlerror: /lib/security/pam_nologin.so: cannot open shared object file: Too many open files] Oct 16 04:48:11 host dovecot-auth: PAM adding faulty module: /lib/security/pam_nologin.so Oct 16 04:48:11 host dovecot-auth: PAM unable to dlopen(/lib/security/pam_stack.so) Oct 16 04:48:11 host dovecot-auth: PAM [dlerror: /lib/security/pam_stack.so: cannot open shared object file: Too many open files] So, during the event I performed an strace against the dovecot-auth process and noticed the following error as well: accept(3, 0xbfe05a50, [2]) = -1 EMFILE (Too many open files) gettimeofday({1192538310, 41972}, NULL) = 0 poll([{fd=3, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL, revents=POLLIN}, {fd=0, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=18, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=10, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=7, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=23, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=8, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=11, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=12, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=13, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=14, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=19, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=16, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=17, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=6, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=15, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=20, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=21, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=9, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=22, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=24, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=25, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=26, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=27, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=28, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=34, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=33, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=29, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=37, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=30, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=31, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=41, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, ...], 1020, 1585) = 1 gettimeofday({1192538310, 99354}, {480, 0}) = 0 Then I checked for the current network connections: netstat | grep imap | wc -l 42 Then used lsof to check for open files: while true ; do lsof | awk '{ print $3 }' | wc -l ; sleep 4 ; done 21728 21668 (restarted dovecot) 1838 1953 1864 2066 2018 2020 2036 2189 2661 2558 2490 (cont @2,000) Thanks!

[Dovecot] Problem in mbox-sync.c
by Hal Pomeranz 27 Oct '07

27 Oct '07

We've just cut over to a new mail server running Dovecot 1.0.5. The underlying OS is RHEL 5. User mailboxes are stored in Unix mbox format on a local ext3 file system. The MTA on the system is the default RedHat version of Sendmail 8.13.8 with procmail for local delivery. We're using a combination of dotlock and fcntl style locking. The output of "dovecot -n" for this system appears below my signature. Periodically we see errors like the following in our logs: Oct 21 19:36:01 postoffice1 dovecot: POP3(someuser): file mbox-sync.c: line 1433 (mbox_sync_handle_eof_updates): assertion failed: (file_size >= sync_ctx->expunged_space + trailer_size) Oct 21 19:36:01 postoffice1 dovecot: POP3(someuser): Raw backtrace: pop3 [0x809eda1] -> pop3 [0x809ecbc] -> pop3(mbox_sync+0x1088) [0x806c4e8] -> pop3(mbox_storage_sync_init+0x3e) [0x806cb6e] -> pop3(client_create+0x1a4) [0x80552a4] -> pop3(main+0x556) [0x8057236] -> /lib/libc.so.6(__libc_start_main+0xdc) [0x304dec] -> pop3 [0x8054a11] Oct 21 19:36:01 postoffice1 dovecot: child 24409 (pop3) killed with signal 6 Note that while the above log is for a POP3 user, we also see similar behavior when some users access mail folders via IMAP as well. The real problem with this behavior is that sometimes, but not in all cases, the process will leave behind a dotlock when it exits. If the abandoned dotlock is on the user's inbox, then procmail won't deliver new mail to the user until the lock is cleared. This is a big problem. Anybody seen this behavior before and/or know what's causing it? Can anybody suggest ideas for further debugging this issue? We'd appreciate any help that you all can provide.

[Dovecot] master user can not login with digest-md5 password
by Daniel 27 Oct '07

27 Oct '07

Hi! I'm trying to use a master user, here is what I'm doing: dovecot.conf: auth default { [...] passdb passwd-file { args = /etc/dovecot.passdb_master pass = yes master = yes } passdb passwd-file { args = /etc/dovecot.passdb } [...] } (Dovecot said that one can not place the passdb containing "master = yes" last, why?) This only works if the master user (in the master passwd file) has PLAIN password scheme. It doesn't work with DIGEST-MD5. Here is the log when it's in DIGEST-MD5: auth(default): passdb(master,84.x.x.x,master): Master user logging in as leva auth(default): digest-md5(leva,84.x.x.x): password mismatch imap-login: Disconnected: user=<leva>, method=DIGEST-MD5, rip=84.x.x.x, lip=212.x.x.x, TLS When the master password is in PLAIN scheme, I can login as anyone. I'm using dovecot-1.1beta4. Daniel

[Dovecot] Messages not marked as read
by Manilal K M 27 Oct '07

27 Oct '07

Hello everybody, Recently I have migrated my IMAP server from Courier-IMAP to dovecot. The migration was successful and all the users are happy due to the speed of the new IMAP server. We are using Horde-3.2+IMP-4.2 as the webmail client. But one of the users is having some unusual issues with his mailbox. Whenever he clicked and open a new email, it's never marked as read. He has to click and open several times to get it marked as "Read". I checked the dovecot version and found that we have a unstable version. So I upgraded to the latest stable version(1.0.5). But still occasionally he has the same issue. Does anyone have experienced similar issue. Please share. regards -- Manilal K M. http://linuxeyes.blogspot.com http://flossvalley.blogspot.com Better to light one candle than to curse the darkness.

[Dovecot] Keywords (labels) support via virtual folders
by Robert Tomanek 27 Oct '07

27 Oct '07

Hi all, while I am rather a beginner when it comes to IMAP, I was thinking whether it would be possible (and feasible) to implement setting and unsetting of IMAP keywords with the means of virtual folders in Dovecot. The background is that the IMAP keywords seem to be a very useful thing to me: I would often like to be able to 'tag' a message so that it is easy to group with other similar messages and easy to find/ browse later. The problem is that not all IMAP clients support this functionality (as far as I am aware, mine which happens to be The Bat! does not); the only way of achieving similar results is using regular folders for grouping messages but this has several disadvantages, the most prominent one being unable to assign more than one 'tag' to a message this way (without copying a message). What I am thinking of is a server-side 'helper' that intends to achieve functionality similar to native client keywords support by the means of providing 'virtual folders' (as opposed to regular folders that we've known for a long time). The server would expose a list of virtual folders (user defined, either server-side by modifying the configuration, or client-side, by using the existing 'create regular folder' folder functionality but using a special name format that would be recognized by the server to be virtual folder related). These virtual folders would, upon moving a message to them, apply a keyword to the message (but the message would not be moved as it would be the case with regular folders). Upon moving a message from a virtual folder, the keyword would be reset. This means that the messages would not normally be moved from their place in existing hard folder structure but they would additionally be flagged with a keyword (or more of them) and be visible in respective virtual folders. The result is: - keywords support for clients that do not natively support it, - leaving existing message folder structure intact, - support for multiple keywords/ labels per message (one virtual folder = one keyword), - browsing flagged messages via respective virtual folders. What do you think of it? While I've been toying with this and similar ideas for a long time, what I propose above is of course heavily influenced by the recent addition of IMAP access to Gmail ([1]). While I still do not have it enabled for my account, I presume this is how the Gmail labels get translated to IMAP client ([2], [3]).

[Dovecot] few questions about 1.1*
by Daniel 27 Oct '07

27 Oct '07

Hi! I'm testing 1.1, and have some questions. (How) Can I override the default maildir++ quota setting (I mean quota_rule) in the userdb, so that one won't have quota at all. Right now I'm setting a very high limit in the userdb with quota_rule=*:storage=99G in the extra field. Prior to 1.1 I was using 1.0 and had fs quota. I've had set up dovecot so that the indexes were stored on another partition where there were no fs quotas for the users. Now I'm trying to use maildir++ quota, and wondering if there is still any use of keeping the index files on a separate partition. This will be maybe a bit stupid, but do I still need the quota plugin to be loaded in the protocol {imap,pop3,lda} sections if I'm using the above mentioned new 1.1 maildir++ quota? Furthermore, will deliver be aware of the new quota system? Thanks! Daniel

[Dovecot] sieve filtering, rewriting subjects
by Ian P. Christian 26 Oct '07

26 Oct '07

Is it possible to modify an emails subject line in a sieve script? I've seen references to 'addtag' whilst googling, but it appears dovecots implementation doens't support it - are there any other methods? As a side note, can anyone suggest a web based script editor that works? Simply a text area to write the script in would do Thanks, -- Ian P. Christian ~ pookey.co.uk

[Dovecot] SSL help needed - "no root certificate"
by Jim Gottlieb 26 Oct '07

26 Oct '07

Hi. I've spent the past few hours trying to get SSL working right in Dovecot 1.0.5 and now I must turn to you for help. I purchased an SSL certificate from Go Daddy. I pointed ssl_cert_file to the .crt file and ssl_key_file to the .key file, but the client (Mail.app) complains: Mail was unable to verify the identity of this server, which has a certificate issued to "imap.nccom.com". The error was: There is no root certificate for this server. So I tried downloading Go Daddy's root certificate and pointing ssl_ca_file to that file, but that didn't help. So I tried pointing ssl_ca_file to the intermediate certificate sent to me by Go Daddy, but that breaks things to the point where I never even get the above message; just nothing happens at all. I'm not sure what to try next and am happy to entertain any suggestions. Thanks...

[Dovecot] SSL/TLS with Outlook client
by Eli 25 Oct '07

25 Oct '07

I am trying to get TLS to work with Outlook 2007 and I've hit a small problem. Whenever I start it up, I get this error: "The server you are connected to is using a security certificate that cannot be verified. The target principal name is incorrect." (yes/no choice of trusting) I first tried with a wildcard cert (*.elisand.com), and then tried with mail.elisand.com - both certs are from cacert.org and the root CA certs are installed and functioning properly on my system (so the certs should be trusted). I've searched all over Google and such trying to find out why Outlook would give me this error from an IMAP/TLS connection (closest I could find was Exchange related info), and I know this is by no means an Outlook mailing list... though I'm just wondering if anyone else on here has ever encountered this problem before and could point me in the right direction to getting the SSL cert working with Outlook. Thanks in advance!

[Dovecot] How to debug slow operation
by zbigniew szalbot 24 Oct '07

24 Oct '07

Hello, I am no programmer at all. I have dovecot set up on two very similar machines. On one of the boxes, the dovecot server has recently been showing slower response times. It feels slower. Where it is slower, dovecot works as an auth server for postfix. I have replaced exim with postfix on that box and I think since then dovecot started to slow down. On the other machine the MTA is exim. I'd like to ask how to go about debugging the problem. Neither machine serves many users, the one that is slower has currently only two. It's a home setup really. Here's the output of dovecot -n # 1.0.5: /usr/local/etc/dovecot.conf protocols: imap imaps pop3 pop3s disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login login_greeting: Server ready. verbose_proctitle: yes first_valid_uid: 125 first_valid_gid: 125 mail_extra_groups: mail mail_location: maildir:/usr/local/virtual/%d/%n 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/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 imap_client_workarounds(default): delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(imap): delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(pop3): outlook-idle pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: mechanisms: plain login passdb: driver: sql args: /usr/local/etc/dovecot-postfix-sql.conf userdb: driver: sql args: /usr/local/etc/dovecot-postfix-sql.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 384 user: postfix group: postfix Many thanks for your suggestions!

[Dovecot] graceful failure when some folders are not available...
by bhayden＠umn.edu 23 Oct '07

23 Oct '07

Hi folks. Quick question in the hopes that someone knows the answer, before I dig in the code some more. In testing a new setup with some long-term archival mbox-format mailboxes stored on an NFS mount, we've found the following: if the mount is unavailable for any reason, the user cannot log into their email at all. Dovecot says: "stat() failed with mbox foo" and dies. This is coming from the mbox sync checks. (It's possible the same happens with a maildir folder--I'm just specifying mbox because that's what we've tested with so far). Is there a way to reconfigure this behavior? I could maybe see a fatal abort if the inbox is unavailable, but for other folders it seems rather... presumptuous. I have to think there's already a way to handle this more gracefully in the config and I'm just not seeing it. Also, does anyone know offhand if this behavior is the same for folders that aren't in the default/inbox namespace? That would seem *really* wrong. Any thoughts? Thanks much, -Brian

[Dovecot] trying to enable features
by Ray 23 Oct '07

23 Oct '07

Hello all, I'm trying to enable 3 different features in my mail system (postfix, amavisd, dovecot). 1)out of office auto reply 2)script execution based on email 3)automatically add disclaimer/signature to outgoing email (also listed in order of importance to me) I'm looking for pointers to documentation or instructions. It seems that 1 and 2 would best be done in dovecot somewhere, while 3 is probably best implemented in postfix. (my next step is postfix documentation) Can anybody provide any suggestions or pointers to a how to or other documentation? Thanks, Ray

[Dovecot] Courier to Dovecot: problems with folders
by Claudio Strizzolo 22 Oct '07

22 Oct '07

Hi all, I am migrating a maildir Courier-IMAP installation to Dovecot. Almost everything seems to work well, but I still have problems accessing subfolders. First let's see what I have done. I used the courier-dovecot-migrate.pl script suggested in http://wiki.dovecot.org/Migration/Courier to convert mailboxes from Courier to Dovecot. No problems here. My dovecot.conf contains this: (...) mail_location = maildir:/mail/vmail/domains/%h namespace private { prefix = INBOX. inbox = yes } (...) The subscriptions file in the mailboxes looks correct to me. It includes all the folders and subfolders, i.e.: Sent Trash Drafts mail.dovecot mail.misc mail.postmaster tools web.apache web.css Folders separated by "." are actually subfolders: mail ---- dovecot | --- misc | --- postmaster I let the configuration of my IMAP clients unchanged from Courier to Dovecot. That is, they specify the "INBOX." prefix, as before. For instance, with Pine: folder-collections=mymail {mymail.example.com/user=John.Smith}INBOX.[] Now the problem: I get different behaviours depending on the client I use to access to Dovecot: - Thunderbird: All the folders are seen correctly. But the whole folders tree is under "Inbox", while with Courier the first-level folders (i.e. Drafts, mail, web) were at the same level of Inbox - Webmail (Squirrelmail 1.4.8): The same as above. - Pine: The folders are apparently correct, and are not under Inbox, but I can access only the first-level folders: the folders containing sub-folders are empty, therefore the subfolders cannot be accessed. Any hints? Thanks in advance Claudio

[Dovecot] Squirrelmail: "ERROR: Connection dropped by IMAP server."
by Jakob Hirsch 22 Oct '07

22 Oct '07

Hi, running the current version from http://hg.dovecot.org/dovecot/ (but the same happens with 1.1.beta3) After yesterday's patches, squirrelmail (tested with 1.4.11 and 1.4.10a) complains when appending to the Sent folder (after sending a message): ERROR: Connection dropped by IMAP server. Query: SELECT "INBOX" dovecot's log says dovecot: IMAP(jh): Disconnected: EOF while appending bytes=12780/37798 I have captured the conversation with tcpdump (http://plonk.de/imap.cap) and it looks like dovecot is closing the connection. With Thunderbird it works just fine. Regards, Jakob

[Dovecot] pam_ldap.so memory leaks?
by Flannery, Andrew 22 Oct '07

22 Oct '07

Hello List, I have a question about dovecot-1.1.0-beta3 but first I'll ramble a little bit: Recently I upgraded a 0.99 installation of dovecot to 1.0.5. All went relatively smoothly until the dovecot-auth process began returning "out of memory" after a day. There is a rather large user base here. The current setup is using passdb pam with blocking=yes, with pam_ldap.so handling most authentication (although in special cases I am using a custom written pam module which I have disabled to eliminate as the source of the leak). The dovecot-auth process' VmRSS size grows by 4k per request and has a limit of 256megs. Unfortunately turning blocking=yes off isn't an option. The reason I must have it turned on is that the custom pam module is changing the username on specific requests. I am trying to pinpoint the memory leak (pam_ldap is my biggest suspect right now though I'm going to try running valgrind on a test system). For now I have set shutdown_clients=no and am restarting dovecot at regular intervals. Okay the question: In dovecot 1.1.0 beta3 I see that blocking=yes is now on, no matter what. Has something been done to address potential memory leaks in pam modules? Thanks, -Andrew

[Dovecot] Best version for production systems?
by Mitch Pirtle 22 Oct '07

22 Oct '07

Hi dovecotters, I have a system running 1.0rc1 right now and am having problems (more on that later). I know that 1.0.5 is "current" but I'm running Debian Stable (Etch) and have reservations of upgrading until nothing works anymore ;-) Do I really need to make the upgrade to 1.0.5, and if so can anyone here point out how to do so using the standard Debian apt-get process? -- Mitch

[Dovecot] Migrating from UW IMAP - pine - Thunderbird - squirrelmail
by Israel Bravo 22 Oct '07

22 Oct '07

Hello! I saw your post to the mailing list (http://www.dovecot.org/list/dovecot/2006-January/010968.html) where you write "A description for pine with imap acces without entering any password is also discussed.", but I didn't find such description in this post. Would you be so kind to point me to some source where it is explained - currently users have to insert the password twice - when they open the shell window and when they start Pine. Another question - may be you can help me: Currently we use Pine with IMAP (dovecot); both INBOX and folder collection are saved on the Linux server. But how to save the "saved-messages" and "sent-mail" folders in the user's home directory on the server?

[Dovecot] assertion failed: (mailbox_list_is_valid_existing_name(_list, name))
by Adam McDougall 21 Oct '07

21 Oct '07

When I was initially testing dovecot 1.1b2,3 I had ACLs turned on and encountered this problem below. I had them turned off until now, I'll need to have ACLs working before I can widen testing. I'm not sure how to make "env MAIL=maildir:~/Maildir gdb /tmp/imap" load the ACL plugin so I assume that is why it does not crash; not getting any log either from that, maybe I made a mistake? But when running mutt, I can load it up with the inbox, then when I ask for imap://server/mail/ it crashes with the assertion at the bottom. Let me know if I need to provide more info. Thanks.

[Dovecot] Upgrade from 1.0.1 -> 1.0.5 failed (rc 75)
by Andy Shellam (Mailing Lists) 21 Oct '07

21 Oct '07

Hi, I'm using a mixture of Exim, Dovecot and Deliver. Exim receives the mail and validates the user against our database, then pipes the e-mail to deliver which puts it in the right mailbox. We were running Exim 4.67 and Dovecot 1.0.1, and today I did an in-place upgrade to Dovecot 1.0.5 and Exim 4.68. However, now Exim is failing deliveries saying deliver returned code 75. If I examine the dovecot log file, I'm getting errors like: deliver(andy.shellam-lists(a)mailnetwork.co.uk): Oct 21 17:19:49 Fatal: chroot(/users/mail/andy.shellam-lists(a)mailnetwork.co.uk) failed: Operation not permitted All mailboxes are owned by user "dovecot-mail" and group "localservice", with user and group having full permissions, and other having no access (0770). None of the config files (Exim nor Dovecot's) have changed, nor have permissions on the mailbox paths, and Dovecot can still access the mailboxes through IMAP just fine. If I delete the dovecot log-file and force a mail delivery, the log gets re-created with mode 0644 and owner dovecot-auth:localservice, which confirms the user running dovecot is the same group, so why doesn't it have permissions? I've read on another message that return code 75 is EX_TEMPFAIL, what does this mean? My sendmail_path is the correct path to Exim, verified by killing Exim and copying and pasting the command to start it back up again. Any advice would be appreciated, as I may have to restore back to 1.0.1.

[Dovecot] dovecot? putting wrong seperator in subscriptions file
by Adam McDougall 21 Oct '07

21 Oct '07

My config has folders show up in the root namespace as well as hidden ones like mail/ for compat. In thunderbird when I set the namespace prefix to mail/, I effectively cannot subscribe to folders. You can pull up the folder list, select some folders to subscribe to, hit okay, and nothing changes in thunderbird: 3 subscribe "mail/Spam" 3 OK Subscribe completed. 4 lsub "" "mail/*" 4 OK Lsub completed. What gets put in my subscriptions file: mail.Spam If I manually change my subscriptions file to mail/Spam, it works as expected. # dovecot -n # 1.1.beta3: /usr/local/etc/dovecot.conf ssl_cert_file: /usr/local/etc/apache2/ssl/cert.pem ssl_key_file: /usr/local/etc/apache2/ssl/cert.pem disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login verbose_proctitle: yes first_valid_uid: 1000 first_valid_gid: 0 mail_location: maildir:%h/Maildir:CONTROL=%h/Maildir/dovecot/private/control:INDEX=%h/Maildir/dovecot/private/indexes mail_debug: yes mmap_disable: yes mail_nfs_storage: yes mail_nfs_index: yes mail_plugins: mail_log mail_log_max_lines_per_sec: 0 imap_client_workarounds: delay-newmail netscape-eoh tb-extra-mailbox-sep imap_logout_format: bbytes=%i/%o username=%u namespace: type: private separator: / prefix: mail/ location: maildir:%h/Maildir:CONTROL=%h/Maildir/dovecot/private/control:INDEX=%h/Maildir/dovecot/private/indexes hidden: yes namespace: type: private separator: / inbox: yes list: yes auth default: mechanisms: plain login passdb: driver: pam userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/auth mode: 384 user: postfix group: postfix plugin: acl: vfile:/usr/local/etc/dovecot-acls

[Dovecot] two small low importance issues in 1.1b
by Adam McDougall 21 Oct '07

21 Oct '07

Item 1: I store the indexes and control in their own directory. I noticed in 1.1: 1192 ./private/indexes/.INBOX 32 ./private/indexes/.Trash 1228 ./private/indexes 4 ./private/control/.INBOX/.INBOX 84 ./private/control/.INBOX 4 ./private/control/.Trash/.Trash 12 ./private/control/.Trash 100 ./private/control 1332 ./private .INBOX/.INBOX and .Trash/.Trash are both empty. This was an empty directory, I logged in with thunderbird and looked at the inbox and Trash folders. Item 2: I wanted to try imap_logout_format, forgetting what params it uses and taking a stab at it, but it seems to be ignored? It shows up in dovecot -n. I made it 'bbytes' just to see if the intentional typo would come through, but no: imap_logout_format: bbytes=%i/%o username=%u dovecot: IMAP(mcdouga9): Disconnected: Logged out bytes=439/169567

[Dovecot] dovecot 1.1.beta3 crashes on NetBSD/sparc64 4.0_RC3 with Thunderbird 2.0.0.6
by Lloyd Parkes 21 Oct '07

21 Oct '07

Hi all, I'm getting core dumps from Dovecot when using Thunderbird as a client. Everything is fine when using the Apple Mail client. I've appended the debug dumps to this message so they are out of the way, but they should be read now. I think the problem might be that io->prev and io->next aren't reliably initialised in ioloop.c:io_add. The value that io->prev has when the program crashes is just completely bogus. It isn't aligned correctly, and it doesn't point to anywhere inside the process's memory map. I don't know what *io->next is, but it sure doesn't look like a struct io_file. It doesn't even look like a struct io. Part of the garbage in *io->next is the char sequence "/vol/home/lloyd/Maildir/new" which is part of my mail box. *io is not in the doubly linked list in current_io_look->io_files. I'm guessing that this object has been unlinked already. Some further digging (not shown here) shows that io->callback is notify_callback. It is set to NULL by the time imap crashes. Here are all the gory GDB details: Version: 1.1.beta3 OS: NetBSD 4.0_RC3/sparc64 (a 64 bit big endian architecture) Client: Mozilla Thunderbird 2.0.0.6 bt full: #0 0x00000000001e846c in io_file_unlink (io=0x32e2c0) at ioloop.c:54 No locals. #1 0x00000000001e8568 in io_remove (_io=0x3420a8) at ioloop.c:82 io_file = (struct io_file *) 0x32e2c0 io = (struct io *) 0x32e2c0 #2 0x000000000017a0a4 in index_mailbox_check_remove_all (ibox=0x331048) at index-mailbox-check.c:118 file = (struct index_notify_file *) 0x0 aio = (struct index_notify_io *) 0x3420a0 #3 0x0000000000139850 in maildir_notify_changes (box=0x331048) at maildir-storage.c:824 mbox = (struct maildir_mailbox *) 0x331048 #4 0x00000000001c0724 in mailbox_notify_changes (box=0x331048, min_interval=0, callback=0, context=0x0) at mail-storage.c:544 No locals. #5 0x00000000001c074c in mailbox_notify_changes_stop (box=0x331048) at mail-storage.c:550 No locals. #6 0x00000000001167fc in idle_finish (ctx=0x3380b0, done_ok=true, free_cmd=true) at cmd-idle.c:48 client = (struct client *) 0x334100 #7 0x0000000000116a04 in idle_client_input (ctx=0x3380b0) at cmd-idle.c:90 client = (struct client *) 0x334100 line = 0x33a075 "DONE" #8 0x00000000001ea2ac in io_loop_handler_run (ioloop=0x320080) at ioloop-kqueue.c:149 ctx = (struct ioloop_handler_context *) 0x32e080 events = (struct kevent *) 0x332000 event = (const struct kevent *) 0x332000 tv = {tv_sec = 0, tv_usec = 999441} ts = {tv_sec = 0, tv_nsec = 999441000} io = (struct io_file *) 0x320a80 events_count = 4 t_id = 2 msecs = 1000 ret = 1 i = 0 __PRETTY_FUNCTION__ = "io_loop_handler_run" #9 0x00000000001e8f28 in io_loop_run (ioloop=0x320080) at ioloop.c:303 No locals. #10 0x000000000012d710 in main (argc=1, argv=0xffffffffffffc978, envp=0xffffffffffffc988) at main.c:293 No locals.

[Dovecot] Problems with dovecot 1.1b3
by Adam McDougall 21 Oct '07

21 Oct '07

I am testing dovecot 1.1 betas on a testing system, hoping to take advantage of self repairing and NFS-capable indexes when 1.1 is sensible to put into production. I ran into a number of issues that I did not have with 1.0, and I think I'll just pick one or more at a time and report them rather than try to report every single issue at once, hoping that some of the fixes will solve more than one problem. I started with 1.1b2 just for record, but the issues seem to be present in 1.1b3 as well. I realized yesterday that using the acl plugin may be complicating my testing and results, so I have disabled it for now and am connecting with plaintext IMAP just so I can sniff connections and see what is happening. I am running it on FreeBSD 6.2-stable from Sep 19 2007. First my dovecot -n output: # 1.1.beta3: /usr/local/etc/dovecot.conf ssl_cert_file: /usr/local/etc/apache2/ssl/ssl.pem ssl_key_file: /usr/local/etc/apache2/ssl/ssl.pem disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login verbose_proctitle: yes first_valid_uid: 1000 first_valid_gid: 0 mail_location: maildir:%h/Maildir:CONTROL=%h/Maildir/dovecot/private/control:INDEX=%h/Maildir/dovecot/private/indexes mail_debug: yes mmap_disable: yes mail_nfs_storage: yes mail_nfs_index: yes mail_plugins: mail_log mail_log_max_lines_per_sec: 0 imap_client_workarounds: delay-newmail netscape-eoh tb-extra-mailbox-sep namespace: type: private separator: / prefix: mail/ location: maildir:%h/Maildir:CONTROL=%h/Maildir/dovecot/private2/control:INDEX=%h/Maildir/dovecot/private2/indexes hidden: yes list: yes namespace: type: private separator: / inbox: yes list: yes auth default: mechanisms: plain login passdb: driver: pam userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/auth mode: 384 user: postfix group: postfix plugin: acl: vfile:/usr/local/etc/dovecot-acls The first thing I did was to try to update my dovecot.conf from 1.0 to work with 1.1. When I started dovecot 1.1 for the first time, I noticed it was listening to 143 but not 993, even though my config was designed for ssl/tls in 1.0 without any listen ports specified: # netstat -a | grep LISTEN | grep imap tcp4 0 0 *.imap *.* LISTEN So, I thought I would try specifying the ports in the config: protocol imap { listen = *:143 ssl_listen = *:993 # .. } Success! # netstat -a | grep LISTEN | grep imap tcp4 0 0 *.imaps *.* LISTEN tcp4 0 0 *.imap *.* LISTEN Initially I was then testing using ACLs, but I disabled it to simplify. One of the more basic problems I've seen is the behavior from "list = no/yes". For the sake of simplicity and example, I've disabled most of the additional public and private namespaces from my 1.0 config. I have some private namespaces with prefix "mail/" and "Mail/" that I wish to provide for users for compatability with clients set with those prefixes. In dovecot 1.0, this worked as expected: namespace: type: private separator: / prefix: mail/ hidden: yes But in 1.1b2 or b3, I never seem to get a list of the contents under mail/ when I tell mutt to default to servername/mail/ as the default folder path. Cases: hidden = yes list = yes a0006 LIST "" "mail" * LIST (\Noselect \HasChildren) "/" "mail" a0006 OK List completed. a0007 LIST "" "mail/%" a0007 OK List completed. mutt lists contents of only "../" and selecting it brings me to the imap root with the expected folders. When ../ is followed, I see all my folders as well as all my folders repeated under mail/ prefix. hidden = yes list = no a0006 LIST "" "mail" a0006 OK List completed. a0007 LIST "" "mail/%" a0007 OK List completed. mutt claims "No such folder" hidden = no list = yes a0006 LIST "" "mail" * LIST (\Noselect \HasChildren) "/" "mail" a0006 OK List completed. a0007 LIST "" "mail/%" a0007 OK List completed. mutt lists contents of only "../" and selecting it brings me to the imap root with the expected folders. When ../ is followed, I see all my folders as well as all my folders repeated under mail/ prefix.

[Dovecot] Problem with fts found against Dovecot hg; examples + trace attached
by Asheesh Laroia 21 Oct '07

21 Oct '07

I've been wanting to try out Squat for full-text indexing for a while now, so I finally gave it a whirl. I did a fresh pull from hg. I have it enabled, but it's taking *forever* to do a query. (Using alpine, I issued a Select command for all messages with some word anywhere, which presumably caused the Squat indexer to run.) I think Dovecot is infinite looping. I thought something was wrong when I attached strace to it for five minutes and saw no calls to read() or open(). I can reproduce the "select takes forever" on a tiny Maildir with 5 messages: http://paulproteus.acm.jhu.edu/bug-report/2007-10-21/broken.tar.gz I've also attached the *.in and *.out files that I think are related to this IMAP conversation. On a different IMAP conversation with the same "SEARCH takes forever" problem, I attached a gdb to the running Dovecot and got this backtrace: (gdb) bt #0 parse_next_body_to_boundary (ctx=0x85746e8, block_r=0xbf92325c) at message-parser.c:332 #1 0x080c1b7d in message_parser_parse_next_block (ctx=0x85746e8, block_r=0xbf92325c) at message-parser.c:717 #2 0xb7f582c2 in fts_mailbox_search_next_nonblock (ctx=0x811c0c0, mail=0x811d380, tryagain_r=0xbf9232bb) at fts-storage.c:175 #3 0x0805f3e6 in cmd_search_more (cmd=0x80feec0) at cmd-search.c:74 #4 0x0805f768 in cmd_search_more_callback (cmd=0x80feec0) at cmd-search.c:112 #5 0x080ce8eb in io_loop_handle_timeouts (ioloop=0x80fb250, update_run_now=true) at ioloop.c:264 #6 0x080cf309 in io_loop_handler_run (ioloop=0x80fb250) at ioloop-poll.c:159 #7 0x080ce7c8 in io_loop_run (ioloop=0x80fb250) at ioloop.c:303 #8 0x08068c9c in main (argc=135213400, argv=0xbf923464, envp=0xbf92346c) at main.c:293 So I do know that it's using the fts system.

I've linked to a fairly small Maildir (five messages) that reproduces the problem for me.

[Dovecot] Multiple server sections for SSL
by Wolfram Schlich 21 Oct '07

21 Oct '07

Hi, I would like to achieve the following with my dovecot server: - listen von FQDN 'mail.foo.example.com'/IP 'A' for imaps and pop3s with an SSL certificate for 'mail.foo.example.com' - listen von FQDN 'mail.bar.example.com'/IP 'B' for imaps and pop3s with an SSL certificate for 'mail.bar.example.com' I stumbled over a posting by Timo made in 2004 that got my attention: http://osdir.com/ml/mail.imap.dovecot/2004-07/msg00133.html Now, what is the correct nesting/structure for the server, protocol, auth, dict and plugin section as well as any other (by default) "non-sectional" configuration options (like 'login_greeting')? I failed to find *any* documentation references on this topic :-( TIA. -- Regards, Wolfram Schlich <wschlich(a)gentoo.org> Gentoo Linux * http://dev.gentoo.org/~wschlich/

[Dovecot] Homedir Access without exposing whole Homedir.
by Dan Mahoney, System Admin 21 Oct '07

21 Oct '07

Hello All, Dovecot 1.0.3 I am coming from UW IMAP, and I'm finding for some reason that mail is getting stored in a variety of places (which I believe, is because by default UW imap allowed access to the entire home directory). All files are mbox. My default delivery location is ~/.mail Thus: * At least a couple of my users have mail in ~/INBOX, as well as ~/INBOX.drafts (not many users so I don't really care about this). * Several of my users have their mail folders in their home directory, AND in a mail folder. For example, my "test case" user, had the following .mailboxlist file: mail/Sent mail/Drafts mail/Spam mail/Trash Sent Items Drafts Deleted Items Junk E-mail Now, here's the question. I'd like to make it so that everyone has what they had before, but that any new folders are created in ~/mail/ (so that if I ever DO decide to convert, I know where to look). What I thought would be useful for this is make the default namespace "", but set it hidden. Then define a secondary namespace (mail) and use that. However, when I did this, and got a mailbox list, it still recursively listed every file in the homedir. Is there a simple way to do what I want? -Dan Mahoney -- "Station!" -Bill & Ted's Bogus Journey --------Dan Mahoney-------- Techie, Sysadmin, WebGeek Gushi on efnet/undernet IRC ICQ: 13735144 AIM: LarpGM Site: http://www.gushi.org ---------------------------

I deleted the dovecot.index.cache file and it still will not display any messages in my inbox when I have the setting to only display the most current 30 days worth of mail.

[Dovecot] v1.1 QUOTA and inbox quota
by Kristian Vlahovicek 21 Oct '07

21 Oct '07

My mail agent is postfix and by default it imposes the INBOX size of 50 meg. I would like my imap mail clients (I'm using Thunderbird) to "see" this and warn me when my inbox fills up. I tried doing it with the old quota system but wasn't successful. With the new quota rule system it looks like per-mailbox quotas are possible, however when I do this: quota = maildir quota_rule = INBOX:storage=50000 I get an error in the log: Sep 28 02:18:31 discworld dovecot: IMAP(kristian): open((null)) failed: Bad address Sep 28 02:18:31 discworld dovecot: IMAP(kristian): Internal quota calculation error Sep 28 02:20:04 discworld dovecot: IMAP(kristian): open((null)) failed: Bad address Sep 28 02:20:04 discworld dovecot: IMAP(kristian): open((null)) failed: Bad address is there any way to get the inbox quota to work properly? I guess many systems use postfix and have 50M inbox limit so it would really be helpful if this information is pushed somehow through imap to the client. thanks, K

Postfix, by defaults, don't do more than 100 concurrent deliveries with the same transport, local in my case. I raised up auth_worker_max_count to 128, to accomodate 100 potential concurrent deliveries plus some pop3/imaps clients. The problem appears with certain frequency. There is no other info in the log besides the error notification. FWIW: I have auth_debug enabled.

[Dovecot] Errata: dovecot + ldap + virtual mailbox: building mail location path
by Claudio Strizzolo 21 Oct '07

21 Oct '07

Hi all again, I've just realized that I did a bad cut&paste in my previous mail, then I rewrite my request. I apologize. I am trying to set up my dovecot configuration using LDAP and virtual mailboxes. I succeeded in authenticating the users correctly with LDAP, but have problems with referencing the correct mail location directory. I manage several domains. The mailboxes are stored under separate directories for each domain: /mail/vmail/domains/writers.com/William.Shakespeare/ /mail/vmail/domains/writers.com/Jack.London/ /mail/vmail/domains/painters.com/Pablo.Picasso/ /mail/vmail/domains/painters.com/Vincent.VanGogh/ Now, I supposed I could build the path by setting the common part of the paths as mail_location into dovecot.conf: mail_location = maildir:/mail/vmail/domains/%h passdb ldap { args = /etc/dovecot-ldap.conf } userdb ldap { args = /etc/dovecot-ldap.conf } userdb prefetch { } and getting the variable part ("domain/user", i.e. writers.com/Jack.London) from the userdb in dovecot-ldap.conf: auth_bind = yes auth_bind_userdn = mail=%u,vd=%d,o=hosting,dc=example,dc=com ldap_version = 3 base = o=hosting,dc=example,dc=com deref = never scope = subtree user_attrs = mail,,mailbox,mail,, user_filter = (&(objectClass=VirtualMailAccount)(accountActive=TRUE)(mail=%u)) pass_attrs = mail=user,userPassword=password,mailbox=userdb_home,mail=userdb_uid,mail =userdb_mail pass_filter = (&(objectClass=VirtualMailAccount)(accountActive=TRUE)(mail=%u)) default_pass_scheme = CRYPT In the LDAP database the fields are something like: mail = Jack.London(a)writers.com mailbox = writers.com/Jack.London uid = Jack.London However, the above does not work. Here is an extract from the log: Oct 16 15:57:07 mymail.example.com dovecot: auth(default): ldap(Jack.London@writers.com,::ffff:127.0.0.1): user search: base=o=hosting,dc=example,dc=com scope=subtree filter=(&(objectClass=VirtualMailAccount)(accountActive=TRUE)(mail=Jack.London(a)writers.com)) fields=mail,mailbox,mail Oct 16 15:57:07 mymail.example.com dovecot: IMAP(Jack.London(a)writers.com): Ambiguous mail location setting, don't know what to do with it: writers.com/Jack.London/ (try prefixing it with mbox: or maildir:) Oct 16 15:57:07 mymail.example.com dovecot: IMAP(Jack.London(a)writers.com): Failed to create storage with data: writers.com/Jack.London Any hints? BTW, I am trying to prefetch, as you see, but I am not sure that works too. Thanks in advance Claudio

[Dovecot] Incomplete Subject Line

21 Oct '07

Hi, since upgrading from 1.0.5 to latest 1.1-hg I get an incomplete subject line for mails autogenerated by one of our systems in the message list (Thunderbird and mutt). When I open the mail the subject line is intact. It appears that the system is using multiline subjects. Example Subject: =?ISO-8859-1?B?SG9zdG1hc3RlcjogMDAwMDEwNjM1OiBOYW1lc2U=?= =?ISO-8859-1?B?cnZlcjogTmV1dmVyZ2FiZSBvZGVyIMRuZGVydW5n?= is printed as Subject: Hostmaster: 000010635: Namese in the Message list and correctly decoded as Subject: Hostmaster: 000010635: Nameserver: Neuvergabe oder Änderung when viewing the message.

[Dovecot] Namespace Question
by Jeff Grossman 21 Oct '07

21 Oct '07

I installed 1.1Beta2 over 1.0.5 last night. My 1.0.5 setup was running with no problems at all. Stupid me overwrote my dovecot.conf file with a vanilla one. I know I know, backup!!! I am pretty sure my old dovecot.conf file did not specify any namespaces, but I could be mistaken. My Thunderbird and Squirrelmail are working fine on the new 1.1Beta2 setup. But, my smartphone running Windows Mobile 5.0 does not see the inbox or my folders. Does anybody know what might be different between 1.0.5 and 1.1Beta2 in regards to pocket outlook? This is on a Gentoo system.

[Dovecot] Migration Issues UW-POP3

I am migrating from UW's POP3 server (mbox), to Dovecote (mbox -> maildir). Anyway, I am concerned about the Logging details offered by Dovecot, as I manage several details from the logging information provided by UW's Syslog information. Here's a sample of the UW information: Oct 7 22:08:39 ns6 ipop3d[15432]: pop3 service init from 66.207.133.233 Oct 7 22:08:39 ns6 ipop3d[15432]: Auth user=aewhale host=ns.ABS-CompTech.com [66.207.133.233] nmsgs=0/0 Oct 7 22:08:39 ns6 ipop3d[15432]: Logout user=aewhale host=ns.ABS-CompTech.com [66.207.133.233] nmsgs=0 ndele=0 The first time I connected to the server to test the information, I got the following: Oct 7 20:22:17 ns6 dovecot: Dovecot v1.0.rc26 starting up Oct 7 20:22:37 ns6 dovecot: pop3-login: Login: user=<aewhale>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Oct 7 20:23:44 ns6 dovecot: POP3(aewhale): Disconnected: Logged out top=0/0, retr=0/0, del=0/800,size=1576887 None of the other connections reported information about the mailbox or the connections.

[Dovecot] potential maildir folder rename bug

I was expecting to wind up with two folders "INBOX" and "a.b". Instead I got "INBOX" and "a.b.b". I think the problem is that ".a" gets renamed in the filesystem to ".a.b" before src/lib-storage/index/maildir/maildir-storage.c rename_subfolders() is called, which then finds ".a.b", assumes "b" was a subfolder of "a" so renames it. The following may or may not be an appropriate fix. It certainly feels rather ad hoc and I've not thought too deeply about other circumstances where this code is called. I'd certainly appreciate a second opinion. diff -r 8d6433652a33 src/lib-storage/index/maildir/maildir-storage.c --- a/src/lib-storage/index/maildir/maildir-storage.c Sun Sep 30 18:03:17 2007 +0300 +++ b/src/lib-storage/index/maildir/maildir-storage.c Mon Oct 01 20:13:27 2007 +0100 @@ -937,6 +937,10 @@ static int rename_subfolders(struct inde t_push(); old_listname = t_strconcat(oldname, names[i], NULL); + if (strcmp(old_listname, newname) == 0) { + t_pop(); + continue; + } new_listname = t_strconcat(newname, names[i], NULL); oldpath = maildir_get_path(storage, old_listname); newpath = maildir_get_path(storage, new_listname);

[Dovecot] API problem (noob)
by Lars Stavholm 21 Oct '07

21 Oct '07

I'm a bit of a newbie, especially when it comes to dovecot internals, but nevertheless, I need some help: I'm working on a dovecot plugin, and I would like to copy a mail message from the mail store out to a temporary file, less a few headers: static const char *const exclude_headers[] = { "X-DSPAM-Signature" } strcpy(fname, mktemp(fname)); fd = creat(fname, 0600); mail_get_stream(mail, NULL, NULL, &input); output = o_stream_create_fd_file(fd, 0, TRUE); input = i_stream_create_header_filter(input, HEADER_FILTER_EXCLUDE | HEADER_FILTER_NO_CR, exclude_headers, N_ELEMENTS(exclude_headers), null_header_filter_callback, NULL); o_stream_send_istream(output, input); But all I get in the temp file is the message body, i.e. no headers at all. What am I doing wrong here? My understanding (or hope:) of what the function i_stream_create_header_filter() is supposed to do might not be accurate: I was hoping that it would exclude the aforementioned headers, but leave the rest of the headers as is. Any help appreciated /Lars

[Dovecot] Better flagging of errors on logs?

21 Oct '07

Last night dovecot died because of time changed backward. I noticed that the line from dovecot read Oct 9 01:00:44 mailstore16 dovecot: Time just moved backwards by 132 seconds. This might cause a lot of problems, so I'll just kill myself now. Shouldn't such lines have the word "Error" or "Fatal"? If I set the log_path = to a file, will syslog messages still be generated?

[Dovecot] Dovecot raw backtrace when copying to folder
by Julian Cowley 21 Oct '07

21 Oct '07

Seeing a problem with a certain user causing dovecot to crash when copying mail to a folder. This looks similar to a bug someone on the mailing list posted recently. Since the backtrace mentions the index, I tried deleting all of the index files for the user (including subfolders) but it had no effect. Seems that the bug still happens when creating the index for the first time. Unfortunately, I can't pin down if there is a particular message causing the problem but I'll see if I can track it using strace. Lines are broken for clarity. This is dovecot 1.0.5 on CentOS 4.5.

[Dovecot] User database ldap lookups and sasl
by olivier castan 21 Oct '07

21 Oct '07

Hello I'm currently trying to use Active Directory with Unix extensions to store UID, GID and homedir and retrieve them with ldap I don't want to allow anonymous bindings and I would rather not use TLS and manage a PKI. So I'm trying to use SASL to do a Kerberos authentication for Dovecot against AD LDAP. I'm currently getting GSSAPI errors about the lack of "credentials cache". Looking at similar cases where services act as clients, like using nss_ldap for unix host accounts, I understand the credentials cache should be initiated by an external program (cron and startup script), at least with the TGT and maybe the TGS for ldap. Since usually kerberosv5 cache is based on the user id ( /tmp/krb5cc_0 for root) there's an option in ldap.conf (krb5_ccname) to set the filename (/etc/.ldapcache in nss_ldap tutorials) for this cache. Is there any way to do this with dovecot-ldap.conf or should I try to use "auth user" default cache filename ? Thanks in advance

[Dovecot] Howto make deleted itens visible to users?
by "Fábio M. Catunda" 21 Oct '07

21 Oct '07

Hi! I'm using lazy_expunge to backup that are deleted/expunged, but I would like it to be visible to the user. I tried something like: namespace private { prefix = .EXPUNGED/ separator = / location = maildir:~/Maildir/.Apagadas } namespace private { prefix = .DELETED/ separator = / location = maildir:~/Maildir/.Apagadas } namespace private { prefix = .DELETED/.EXPUNGED/ separator = / location = maildir:~/Maildir/.Apagadas/ } But neither OE nor TB shows the messages. (yes, i subscribed the ".Apagadas" maildir). Anybody can give me this little tip? Thanks a lot. []'s, Catunda! !DSPAM:46f1105715318362916074!

[Dovecot] Mail client kill imap-login process
by dovecot acc 21 Oct '07

21 Oct '07

Hi, In my env we have quite a number of old PC which are running windows95. I have installed the thunderbird and outlook97 with the right configuration to dovecot. Everytime I starts the mail client it shows the following, dovecot: Oct 09 10:56:45 Info: imap-login: Disconnected: rip=172.24.65.60, lip=172.24.66.24 only then it shows the login screen. After submit the password, it doesn't seems to login properly. If I use the Outlook Express, it runs ok on the same machine? I can send and read email. I trace the process using strace but it failed since the pid got killed everytime I starts that two mail client. In order to make sure my dovecot run correctly, I run all mail clients from XP and it works like charm. Can someone share with my what should I do next or how to debug further? Thanks.

[Dovecot] Disconnects in log
by Jackie Hunt 21 Oct '07

21 Oct '07

Hi all, I need some help interpreting the info I'm seeing in the dovecot logs. I have a user using Outlook who is having connectively problems. Below is a sample of what the Dovecot log is showing. Can anyone explain to me why multiple logins occur within a few seconds of each other? Also, as I understand it, the "Disconnected" messages mean the kernel told Dovecot the connection was closed. I'm trying to figure out why I'm seeing so many of these. And why they seem to occur shortly after a login. Thanks for any insight!

[Dovecot] verbose_proctitle for proxy processes?
by Onno Molenkamp 21 Oct '07

21 Oct '07

Hi, We're using Dovecot to proxy incoming POP3 and IMAP connections to the right server. We'd like to be able to see what connections are currently open on the proxy servers, without having the parse the log file. For normal mail processes it's possible to use verbose_proctitle for this purpose, but this setting doesn't work for proxy/login processes. Is it possible to do something similar for proxy processes? Even without displaying the username and IP address, it would be useful to be able to see the difference between normal (idle/active) login processes, and proxy processes. Onno

[Dovecot] Per-user quota (with local users)
by Maykel Moya 20 Oct '07

20 Oct '07

I'm migrating to LDAP mi local users, there is the auth section of my dovecot.conf -- auth default { mechanisms = plain socket listen { master { path = /var/run/dovecot/auth-master mode = 0660 user = dovecot group = nusers } } passdb ldap { args = /etc/dovecot/dovecot-ldap.conf } passdb pam { } userdb ldap { args = /etc/dovecot/dovecot-ldap.conf } userdb prefetch { } userdb passwd { } user = root } -- The idea is to try to find the user in the directory and if it isn't found then fallback to a local user lookup. My quota configuration is -- plugin { quota = maildir:storage=10240:ignore=Trash } -- I have some users with particular quotas. With LDAP lookups, there is no problem, in those cases I simply put their particular quota values in their entries and pass it to dovecot via user_attrs. I wonder how to do the same for local users, I mean, to have the ability of specifying particular quotas for some local users. Another doubt is how to express to Dovecot that a user have no quota at all, could I use 0? Regards, maykel

[Dovecot] dovecot and imap session forwarding
by Omer Faruk SEN 20 Oct '07

20 Oct '07

Hi, I was trying to install a qmail-ldap cluster. I have successfully setup dovecot to authenticate against ldap directory. But what I need is to enable imap session forwarding for qmail-ldap. For example when a user connects to a imapserver if the real mailhost of this user is different than the one that is connected so session is forwarded to real mailhost. Normally we can do that with courirer imap using auth_imap binary that comes with qmail-ldap which handles session forwarding. I have done this but got error auth_executable = /var/qmail/bin/auth_imap . Obviously it won't work. But I am not sure where to put /var/qmail/bin/auth_imap http://www.qmail-ldap.info/dovecot.php and http://www.qmail-ldap.info/imap_courier.php page shows a bit information about where to put it. -- Best regards, Omer mailto:omer@faruk.net

[Dovecot] thunderbird and email duplication
by Alexander Banthien 20 Oct '07

20 Oct '07

Hi all, I have recently switched over to Dovecot from CourierIMAP trying for some speedup, which I did get. Installation went OK, so all seemed fine. But suddenly I realised, that incoming emails are replicating themselves. This seems only to happen when connected with Thunderbird. I am also using Squirrelmail and KMail as clients which don't seem to show the behaviour. It seems to happen only for mails received during a Thunderbird session. When I close TBird and reopen it, only newly received messages will show the funny behaviour. The emails are real file copies in the Maildir, I have checked that. Running Dovecot on Debian Etch: dovecot --version: 1.0.0 (this is Debian package 1:1.0.0-1~bpo.1 from backports. I have tried the main package from Debian aswell, same result) with qmail delivering the mails to a Maildir without Dovecot's LDA. Clients: Thunderbird 2.0.0.6 on WinXP over Wireless LAN (tried Thunderbird/Iceweasel on Debian aswell) Squirrelmail and KMail (both running on the same box as Dovecot) don't show that behaviour. Has anybody seen anything similar or have any advice on what to look for? I would like to stick with Dovecot but the way it is looking now, I find working with emails near impossible.

[Dovecot] how to deliver when username and email differ
by Cory Coager 20 Oct '07

20 Oct '07

I have an Active Directory virtual setup and am using LDA to deliver to local recipients. Today I found a big problem with my configuration and not sure if this is fixable. Some of the users have multiple email addresses and the %n variable for user doesn't match their actual username. So if I have realname "Joe Bob" with a username of "joe" and an email of "jbob(a)somewhere.com", deliver will try to deliver to "jbob" and this is wrong. Here is the relevant part of my ldap config: user_attrs = mail,postOfficeBox=home user_filter = (|(mail=%n@%d)(proxyAddresses=%n@%d)(sAMAccountName=%u)) pass_attrs = mail,postOfficeBox=home pass_filter = (|(mail=%n@%d)(proxyAddresses=%n@%d)(sAMAccountName=%u)) Somehow I need to change the username from the LDAP lookup but it seems that the mail attribute does this already. If I switch the mail attribute with sAMAccountName the domain becomes NULL. Anyone know if this is fixable?

[Dovecot] Dovecot v1.0.3 -> Sieve "redirect" command returning Sendmail exit status 75
by Elisamuel Resto 20 Oct '07

20 Oct '07

Hello! My local setup here is Exim 4.68, DSPAM 3.8.0 and Dovecot 1.0.5. Entirely on MySQL tables for virtual hosts and authentication. Dovecot does the authentication for Exim. What I am having problems with, is a simple sieve script to redirect a message that matches the "X-DSPAM-Result" header as "Spam" to another email address. When this rule matches, deliver returns in the log (which is attached) that "Sendmail process terminated abnormally, exit status: 75" What would cause this, and how can I resolve it? Thanks. -- Elisamuel Resto <samuel(a)dragonboricua.net> ID: 0x18615F19 / FP: B66D 1C2A E8EE B922 1D9C D98F D2D5 FB61 1861 5F19

[Dovecot] Problem with bodystructure/partial fetch using 1.1*
by mikkel＠euro123.dk 20 Oct '07

20 Oct '07

Hi there I'm using dovecot-1.1b2/b3 with deliver. All information is stored in an SQL database and no errors related to this issue are written to the logs (actually I get no errors at all). I've run into at problem; FETCH BODYSTRUCTURE is broken after upgrading to dovecot 1.1b2 (same issue with 1.1b3). BODUSTRUCTURE only returns information from the first section (with incorrect content-type/disposition) and discards everything else. This problem is somehow related to deliver; IMAP returns the correct BODYSTRUCTURE for e-mails received before the upgrade, but an incorrect for ones received after the upgrade. This tells me that IMAP is working properly but somehow the MIME sections are being corrupted doing mail delivery (if I fetch the complete body nothing seems to be wrong). Also if I fetch a section something is not right - instead of just the section I get part of the Content-type header as well (but only half the header). Obviously this makes various webmail clients go somewhat crazy while Outlook/Thunderbirds dont mind (since they fetch the complete body and do the MIME parsing themselves). These are my compile options (GCC 3.4.3 on Solaris 10): CPPFLAGS=-I/opt/pkgsrc/pkg/include/mysql LDFLAGS=-L/opt/pkgsrc/pkg/lib/mysql ./configure --prefix=/opt/freeware/dovecot-1.1b2 --with-pop3d --with-deliver --with-mysql --with-prefetch-userdb --with-sql --with-gnu-ld --with-ssl=no --enable-header-install make; make install Everything else works flawlessly.

[Dovecot] Operations error with AD connections
by Maarten Vanraes 19 Oct '07

19 Oct '07

Hello, dovecot version: 1.0.beta3-3ubuntu5.5 OS: 2.6.15-26-server i686 GNU/Linux Ubuntu dapper filesys: ext3 authentication is with ldap (Active Directory) the problem is that after a while with a number of pop3 connections (8 people who have checking every 5 minutes), the ldap_search gives 'Operation Error' . we have tried to use the global catalog, but that doesn't solve the problem. the binding is the problem, we must use binding, cause we don't get a userPassword field. Right now, we have switched to courierLDAP and it works for now, we'll have to see if it persists (we have set an LDAP timeout variable, but don't know if it's related.) The thing is that we have lots of places where can setup something like this with AD, and that for now, we'll probably use courier. dovecot-ldap.conf: hosts = 172.17.80.1:3268 dn = CN=SPIC,OU=Beheerders,OU=Zonnegroep,DC=zonnewende,DC=local dnpass = xxxxxxxxx auth_bind = yes ldap_version = 3 base = dc=zonnewende, dc=local user_filter = (mail=%u) pass_attrs = uid=user,userPassword=password pass_filter = (mail=%u) user_global_uid = 5000 user_global_gid = 5000 any ideas on how to solve it?

[Dovecot] performance?/connectivity? issues after server upgrade
by Udo Rader 18 Oct '07

18 Oct '07

Hi, we are facing some weird performance issues after we upgraded on of our mail servers to a new Opteron 64bit machine. The problem we are facing is that mail retrieval from external clients is incredibly slow. Fetching a mail with say a size of 3MB takes 7 minutes vs. sending exactly the same mail back to our postmaster account is only a question of seconds. I've verified this with various customers and thus I am completely lost here. The only service affected with this massive slowdown seems to be dovecot but unfortunately I cannot think of a way to debug the issue ... System load is absolutely minimal. % dovecot -n # 1.0.5: /etc/dovecot/dovecot.conf log_path: /var/log/dovecot.log protocols: imaps imap pop3 listen: 81.16.98.99 ssl_listen(default): 81.16.98.99 ssl_listen(imap): 81.16.98.99 ssl_listen(pop3): ssl_cert_file: /usr/bestsolution/ssl/certs/mail.bestsolution.at.pem ssl_key_file: /usr/bestsolution/ssl/private/mail.bestsolution.at.pem ssl_parameters_regenerate: 24 disable_plaintext_auth: yes 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 first_valid_uid: 9 mail_extra_groups: mail default_mail_env: mbox:~/mail/:INBOX=/var/mail/%u mail_location: mbox:~/mail/:INBOX=/var/mail/%u mmap_disable: yes lock_method: dotlock maildir_copy_with_hardlinks: yes mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 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 pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %v.%u auth default: mechanisms: digest-md5 cram-md5 login passdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf userdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix Any ideas welcome :-) -- Udo Rader bestsolution.at EDV Systemhaus GmbH http://www.bestsolution.at

[Dovecot] Released v1.1.beta3
by Timo Sirainen 18 Oct '07

18 Oct '07

http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta3.tar.gz http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta3.tar.gz.sig Please try and report any bugs. Beta2 still had a few bad bugs, but I'm hoping this release is near a usable state. I've been a bit busy with school lately so I haven't had time/energy to answer mails in here. The main reason has been this lab course (biochemistry) which ends on friday, so I'll try to start answering mails sometimes next week. Changes since beta2: - SORT fixes. Still buggy? - If Date: header doesn't exist or is broken, fallback to INTERNALDATE (as required by newer sort drafts, which I hadn't noticed before, v1.0.6 will have this too) - Log fatals/panics as such, instead of converting them to errors. - Don't bother logging "returned error 89" if the child process logged a fatal before that. - dovecot.index.cache file may have been updated wrong when saving messages causing all kinds of problems if it was - Some crashfixes

Hello all Tomorrow is the day , I'm gonna migrate all our mailboxes and imap folders from our old mailhub to the new one. In the same time I will migrate from UW to Dovecot , I've read all the stuff about it on the Dovecot web site. I have one question , do I have to care about the .imap cache directory created by Dovecot in any way or will it be "all automatic" when starting Dovecot ? Many thanks -- Cordialement Frank Bonnet

[Dovecot] iPhone 1.1.1 problems.
by Mike Meyer 18 Oct '07

18 Oct '07

I'm having problems with the iPhone client in the 1.1.1 version of the iPhone software. Things with other clients work fine, and the iPhone worked fine before it was upgraded to 1.1.1. Other phones on 1.1.1 failed. I'm still working on testing against the client with the iPhone 1.0.2 software on it. The problem is that the client simply doesn't connect to dovecot. I can see the packets passing back and forth in a number of ways, but haven't been able to see the contents. I tried turning on raw logging, but don't get log files for accesses from the iPhone. What I get are lines like so: Oct 13 00:08:34 bhuda dovecot: imap-login: Disconnected: rip=xxx.xxx.xxx.xx2, lip=xxx.xxx.xxx.xx1, TLS Turning off SSL both ways, and the message changes to: Oct 13 18:21:38 bhuda dovecot: imap-login: Aborted login: rip=xxx.xxx.xxx.xx2, lip=xxx.xxx.xxx.xx1 Tweaking the logging in the firewall reveals something interesting: apparently the phone makes the connection to 993, then dovecot drops the connection, but the phone keeps sending to it (and yes, I've tried setting the firewall to allow arbitrary traffic between the phone and the server). So, first question: is anyone who has clients using iPhone software version 1.1.1 working willing to share config information? Second question: suggestions for things to try to solve the problem? (Other than talk to apple as that process is underway)? For instance, a recipe to sniff the text of the interchange? Final question: Any other information I can provide that might help debug this?
