[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

Hi, I have server with multiple virtual domains and this server also accepts mail for the local domain. I'm using postfix and have the following setup for a virtual sales(a)domain.com mapped to custsales@localhost I was wondering if there is a way to login with the virtual email address, for example sales(a)domain.com? I would also like to still be able to login with the local user as well. TIA, P

Hi! Is it possible to combine these two features of dovecot, i.e. to have a specific namespace that proxies to another IMAP server? Greetings -- Robert Sander

[Dovecot] How to write plugin
by Eugene Prokopiev 20 Nov '07

20 Nov '07

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] umask not applied

Hi all! I am trying to get dovecot-1.0.rc15 to create files with mode 660 in my virtual mailboxes. I set umask=0007 in dovecot.conf, restarted dovecot (/etc/init.d/dovecot restart) and send me an e-mail but it is still 600. "dovecot -n" says "umask: 7" How come the zeros are not displayed? Is this by intention or is something wrong?

[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. This is my ".config": DOVECOT=/usr/src/dovecot-1.0.7 DOVECOT_VERSION=1.0 BACKEND=spamassassin-exec INSTALLDIR=/usr/lib/dovecot/modules/imap/ PLUGINNAME=antispam This is how I make the plugin: make && make install && chmod 644 /usr/lib/dovecot/modules/imap/lib90_antispam_plugin.so Since Ubuntu server does not come with dovecot sources, I have downloaded dovecot-1.0.7 and put it in /usr/src. As far as I understand, only the headers are needed, so this should not be the cause of the crash (if the headers hadn't changed). When invoked from dovecot process, the "imap" dies with signal 11. When running: strace /usr/sbin/dovecot --exec-mail imap This is how it ends: etdents64(8, /* 14 entries */, 4096) = 592 getdents64(8, /* 0 entries */, 4096) = 0 open("/usr/lib/dovecot/modules/imap/lib90_antispam_plugin.so", O_RDONLY) = 9 read(9, "\177ELF\1\1\1\0\0\0\0\0\0\0\0\0\3\0\3\0\1\0\0\0\340\21"..., 512) = 512 fstat64(9, {st_mode=S_IFREG|0644, st_size=19252, ...}) = 0 mmap2(NULL, 16148, PROT_READ|PROT_EXEC, MAP_PRIVATE|MAP_DENYWRITE, 9, 0) = 0xb7f29000 mmap2(0xb7f2c000, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_FIXED|MAP_DENYWRITE, 9, 0x2) = 0xb7f2c000 close(9) = 0 close(8) = 0 stat64("/var/mail/mailboxes/boky/Maildir/subscriptions", 0xbfc17d2c) = -1 EACCES (Permission denied) lstat64("/var/mail/mailboxes/boky/Maildir/cur", 0xbfc17c3c) = -1 EACCES (Permission denied) write(2, "imap(boky): ", 12imap(boky): ) = 12 write(2, "Error: ", 7Error: ) = 7 write(2, "lstat(/var/mail/mailboxes/boky/M"..., 69lstat(/var/mail/mailboxes/boky/Maildir/cur) failed: Permission denied) = 69 write(2, "\n", 1 ) = 1 open("/etc/localtime", O_RDONLY) = 8 fstat64(8, {st_mode=S_IFREG|0644, st_size=696, ...}) = 0 fstat64(8, {st_mode=S_IFREG|0644, st_size=696, ...}) = 0 mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xb7de2000 read(8, "TZif\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\6\0\0\0\6\0"..., 4096) = 696 close(8) = 0 munmap(0xb7de2000, 4096) = 0 stat64("/etc/localtime", {st_mode=S_IFREG|0644, st_size=696, ...}) = 0 --- SIGSEGV (Segmentation fault) @ 0 (0) --- +++ killed by SIGSEGV +++ Process 4707 detached antispam plugin was downloaded from: http://git.sipsolutions.net/?p=dovecot-antispam.git;a=snapshot;h=HEAD;sf=tgz Please advise me n next steps; I'm just a beginner with debugging C/C++.

[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?

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] v2.0 / Master/config rewrite

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.

When performing an imap search, I hit the following assertion failure: imap(vmail): Panic: file unichar.c: line 128 (uni_ucs4_to_utf8_c): assertion failed: (chr <= 0x40000000) imap(vmail): Error: Raw backtrace: /usr/lib/dovecot/imap [0x80c7f7f] -> /usr/lib/dovecot/imap [0x80c7d6a] -> /usr/lib/dovecot/imap [0x80d8616] -> /usr/lib/dovecot/imap(uni_utf8_to_decomposed_titlecase+0x9f) [0x80d892f] -> /usr/lib/dovecot/imap(message_decoder_decode_next_block+0x679) [0x80c46e9] -> /usr/lib/dovecot/imap(message_search_more+0x3e) [0x80c2e8e] -> /usr/lib/dovecot/imap(message_search_msg+0x72) [0x80c3012] -> /usr/lib/dovecot/imap [0x8093f47] -> /usr/lib/dovecot/imap [0x80b7719] -> /usr/lib/dovecot/imap(mail_search_args_foreach+0x32) [0x80b77c2] -> /usr/lib/dovecot/imap(index_storage_search_next_nonblock+0x243) [0x8093af3] -> /usr/lib/dovecot/imap [0x805cdc7] -> /usr/lib/dovecot/imap [0x805d138] -> /usr/lib/dovecot/imap(io_loop_handle_timeouts+0x112) [0x80ce892] -> /usr/lib/dovecot/imap(io_loop_handler_run+0x66) [0x80cf316] -> /usr/lib/dovecot/imap(io_loop_run+0x28) [0x80ce768] -> /usr/lib/dovecot/imap(main+0x4ab) [0x806675b] -> /lib/tls/i686/cmov/libc.so.6(__libc_start_main+0xc8) [0xb7e68ea8] -> /usr/lib/dovecot/imap [0x8059141] My quick analysis: This seemed to be caused by a single message in this mailbox.

[Dovecot] assertion failed: (mailbox_list_is_valid_existing_name(_list, name))
by Adam McDougall 11 Nov '07

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
by Asheesh Laroia 10 Nov '07

10 Nov '07

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. Timo, can you confirm or deny that you still see this behavior? I did clear my indexes before doing it. -- Asheesh. -- Man is the measure of all things. -- Protagoras

[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

[Dovecot] v1.1.beta7 released
by Timo Sirainen 08 Nov '07

08 Nov '07

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.

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

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.

[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] Sieve error messages (sieve 1.1.2, dovecot 1.1b6)

Sorry for spamming the list today:) Im getting a lot of these errors in the deliver log: deliver([recipient]): [date] Info: sieve runtime error: Fileinto: Generic Error deliver([recipient]): [date]:18 Error: sieve_execute_bytecode([path-to-sieve]) failed deliver([recipient]): [date] Info: msgid=<[msgid] >: save failed to [foldername]: Quota exceeded In this case the account is over the defined Dovecot quota limit. Dovecot knows what to do but sieve seems to throw its standard error message. Is there something wrong with Sieve or is it just that the error is misleading? This has been present in all v1.1.x I think (some changes was made to the error messages in b3 or b4 but believe this didnt change). Regards, Mikkel

hi, the current code has changed include linux/inotify.h to sys/inotify.h since 2006-01-17, but that won't work with inotify*.h as documented in the wiki. One has to either revert back to linux/inotify.h, or add #include <sys/inotify-syscalls.h> to both configure.in and src/lib/ioloop-notify-inotify.c Or, just symlink sys/inotify.h -> linux/inotify.h.

[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

The worst errors are things like: Oct 30 16:11:42 delta2 dovecot: IMAP(x): Corrupted transaction log file /home/spamcop-net2/deputies/dovecot.index.log: end_offset (392) > current sync_offset (388) Oct 30 16:11:42 delta2 dovecot: IMAP(x): file mail-index-sync-update.c: line 841 (mail_index_sync_update_index): assertion failed: (view->hdr.messages_count == map->hdr.messages_count) Oct 30 16:11:42 delta2 dovecot: IMAP(x): Raw backtrace: imap [0x462a7e] -> imap [0x46234c] -> imap(mail_index_sync_update_index+0x7b2) [0x44a982] -> imap(mail_index_sync_commit+0xe7) [0x447f87] -> imap(maildir_sync_index_finish+0xd2) [0x420b32] -> imap [0x4225af] -> imap(maildir_storage_sync_init+0x63) [0x4227b3] -> imap(imap_sync_nonselected+0xf) [0x41be9f] -> imap(_cmd_select_full+0xc5) [0x413f95] -> imap(cmd_select+0xb) [0x41411b] -> imap [0x415a87] -> imap [0x415b2c] -> imap(_client_input+0x75) [0x415cd5] -> imap(io_loop_handler_run+0xee) [0x4684ce] -> imap(io_loop_run+0x2d) [0x46797d] -> imap(main+0x3e3) [0x41d7b3] -> /lib/libc.so.6(__libc_start_main+0xdb) [0x2aaaaace049b] -> imap [0x410cca] When this happens, my users just get timeouts trying to do stuff. I have my messages (maildirs) and indices all stored on NFS. For locking, I have mmap_disable = yes and lock_method = dotlock Do you have any idea what is going on here? In general, I get tons of errors about corrupted transaction log files for all users. Is this normal? Thanks Jeff

[Dovecot] v1.1.beta5 released
by Timo Sirainen 02 Nov '07

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.

Re: [Dovecot] Dovecot push imap/imap notify support?

Mart Pirita <sysadmin(a)e-positive.ee> wrote: > Tried search, no luck, does the Dovecot include push imap/imap notify support? If you're looking for something iPhone-compatible, then "no." 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

02 Nov '07

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 1.0 configuration file base_dir = /var/lib/dovecot protocols = imap pop3 imaps log_path = /var/log/dovecot/error.log info_log_path = /var/log/dovecot/info.log first_valid_uid = 60000 last_valid_uid = 60000 first_valid_gid=15 last_valid_gid=15 default_mail_env = maildir:/var/spool/mail/%d/%u mailbox_check_interval = 60 maildir_copy_with_hardlinks = yes mbox_locks = fcntl umask = 0077 auth default { mechanisms = plain digest-md5 user = dovecot passdb pgsql { /etc/dovecot/dovecot-pgsql.conf } userdb pgsql { /etc/dovecot/dovecot-pgsql.conf } socket listen { master { path = /var/run/dovecot/auth-master mode = 0660 user = postfix group = mail } client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = mail } } } but the same configuration on the newer version 1.0.5 does not work, the problem being in mail location (note changed from default_mail_location to mail_location). so i had to make a number of changes... ##

[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!"

[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

Thanks for the quick fix. 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
