[Dovecot] Sieve regex never matches
by frank.kintrup＠fkware.de 26 Nov '07

26 Nov '07

Hi, I found the following code on the net which should redirect all mails to another address depending on the time of day (useful for forwarding mails to work): require ["regex"]; if allof (header :regex "date" "(08|09|10|11|12|13|14|15|16|17):..:..", not header :regex "date" "(sat|sun)") { redirect "address@work>"; keep; } To check and test I simplified the regex to match all mails within a certain hour: require ["regex"]; if header :regex "date" "20:..:.." { redirect "user@domain"; keep; } Both scripts compile fine, but their regex never match. Has anyone an idea why? I'm using Dovecot 1.0.0 on Debian Etch stable. Frank

[Dovecot] passdb ldap static values
by Harrison Metzger 26 Nov '07

26 Nov '07

Hello, In the pass_attrs field one can map ldap attributes to dovecot attributes. I'm wondering if I can map both ldap attribuets and static attributes to a dovecot value in the same passdb section. Also, I can't seem to find what other values (if any) can belong in the: passdb ldap { args = /path/filename } stanza. Are there any other options I can put in that stanza, I can't seem to find any on the wiki. Harrison Metzger

[Dovecot] recalculation of maildir Quota
by Ingo Rogalsky 26 Nov '07

26 Nov '07

Hello, I intend to use maildir Quota for measurement only, not for applying restrictions. Therefore I defined rather high values. That's working as expected. Nevertheless it's not useful, because the recalculation time is to high. This takes some minutes for my own mailaccount with 250.000 mails on a NFS storage. This would be to bad, but whilst this time, the Mailclient hangs. Probably our users woulnd't accept this. Can this be done in the background? Furthermore I noticed that recalculation occurs after the file maildirsize gets longer than 30 lines (around 250-300 bytes) and not after 5120 bytes as the wiki states. Do I do/understand something wrong or is this a bug? Probably a nightly cronjob, which does calculation of Maildir-size would be a more useful alternative. Regards, Ingo Rogalsky

[Dovecot] migrating from mbox to maildir
by Erick Perez 26 Nov '07

26 Nov '07

Hi all, I have a locking problem in a Centos 4.4 linux machine with the following config: dovecot-0.99.11-8.EL4 postfix-2.2.10-1.1.el4 I use virtual mailboxes with postfix currently I have dovecot with mbox as this: default_mail_env = mbox:/var/mail/virtualmail/%d/%n The problem is that mail is being delivered to mailboxes very very slowly (sometimes up to 4 hours). In my logs, I have tons of these messages: mail postfix/virtual[24965]: CFB8878D04F: to=<REMOVED@REMOVED>, relay=virtual, delay=51, status=deferred (mailbox /var/spool/mail/virtualmail/REMOVEDDOMAINNAME/npitti: unable to lock for exclusive access: Resource temporarily unavailable) then someone told me that I need to change dovecot to maildir format. Is there a reference to change format? Or some comments about this? Thanks in advance.

[Dovecot] Squat full text search indexer redesign
by Timo Sirainen 26 Nov '07

26 Nov '07

I was writing this to beta9 announcement, but it grew so huge that I guess a separate mail is better. :) I've spent quite a lot of time this last week redesigning/rewriting Squat indexer. I think the redesign is good enough now that I'll just replace the existing squat with this new one in next release. I don't think many people are using the old squat, and there are also some bugs in it that cause some searches not to find anything (haven't tried to fix it). The old Squat indexes about 3MB/s on my machine while the new one indexes 8MB/s. Or it's actually 10MB/s, but at the end of indexing it does a compression step that merges all fragmented UID lists. That drops the index size something like 5-10%, but it's pretty slow because it has to go through all the fragmented lists. It could probably be optimized to be a lot faster, but I think I'll forget about it for now. Besides being faster there are other improvements in it: - Old squat could answer only 4 character long substring searches. New squat can answer 1..n characters long substring searches, where n can be configurable. The larger the n, the larger the index size. For example 4..10 index sizes are about 35% -> 46% -> 53% -> 59% -> 63% -> 67% -> 70% of the mailbox size (with 32MB of Dovecot mailing list archives). With both old and new squat if the search keyword is longer than n, Dovecot looks up the list of all possible n char long combinations of the word, gets a list of their common UIDs and then reads those mails to verify that the word is really found from them. - New squat can also be configured to index longer words for non-substring searches. This allows it to give a definite list of UIDs where the word is found, so Dovecot doesn't have to open those mails to verify it. However it can't give a definite list of UIDs where the substring isn't found. So it still has to do the n-char-combination lookup described above, and for those returned UIDs which aren't also in the definite-UIDs list Dovecot still has to read them to check if the substring is found or not. This could be skipped for non-standard X-FAST-TEXT and X-FAST-BODY searches which don't try to search substrings. Adding 255 char long non-substring searches to 4 char long substring searches grows the index about 7% (35%->42% for 32MB, 28%->36% for 200MB, 27%->33% for 1,4GB). Unfortunately it also grows memory usage pretty much. For a 200MB mailbox heap usage grows from 34MB to 163MB. For 1,4GB lkml mailbox heap usage grows from 80MB to 700MB. So I'm not sure if this should be enabled by default until something can be done about the memory usage. - The current list of indexed characters are: A-Z, 0-9, @.-+#$%_& and all 8bit chars. When trying to search for non-indexed characters Dovecot has to split the search word. For example "a,b" would search "a" and "b", combine the results and then open those mails to see where it really exists. The same thing happens with "a b". If the search word doesn't contain any indexable characters, Dovecot has to read all mails. This indexable character list could be changed runtime, so if a user keeps searching for some non-indexed character, it could be added to indexed characters and the index be rebuilt. - To be able to give definite replies for BODY searches squat has to keep track of whether a word was found from body or header. This also optimizes HEADER searches because then Dovecot has to search only those mails that have the word in their headers, instead of the mails that have it in either header or body. Unfortunately this makes the indexes somewhat larger again (22%->28% for 200MB), but I think this should be done by default. The header+body is stored by storing UID 1=message 1 header, UID 2=message 1 body, UID 3=message 2 header, etc. I haven't yet tried how well the UID lists could be compressed if could support only-header or only-body ranges. For example now if word is found from all headers but from no bodies, it stores the UID list as 1,3,5,7,etc, while it could be stored as simple "only bodies, 1:7". I guess the UID list compression could use all kinds of other algorithms as well. Currently it supports only the whole list being either a bitmask or UID range. A long UID list might compress better as a bitmask +range combination. UID lists take most of the Squat space, so even small improvements can give huge benefits. If you're interested in trying, you can download the current test code and modify uidlist_write_array() for writing and node_uidlist_get_at_offset() for reading. http://dovecot.org/tmp/test.c http://dovecot.org/tmp/test-uidlist.c Place to src/plugins/fts-squat/, run with ./test some-mbox-file Another somewhat different idea to substring indexing (suggested to me by someone else) would be to index the messages' words normally like most indexers do, and then use Squat indexes for those words. So for example when searching for "ord" it first looks up all words that contain "ord" substring in them. Then it looks up message UIDs for those words, and the resulting UID list is a definite list of messages that has the substring. I'm not sure how well the above would work in practise. If the list of words would be mostly static it would work great. Unfortunately every mail has at least two unique strings: Message-ID and Received header's ESMTP ID. Dovecot must be able to search those as well. Also with some languages, like Finnish, a single word can be written in tens of different ways and combined with other words. A quick preliminary testing for 32MB Dovecot mailing list shows: - 142265 unique words takes 2,0MB, one per line - indexing those words creates 6,7MB Squat indexes So not including extra overhead for the unique word index, these use a total of 8,8MB. 4-char-substring Squat indexes for the same mailbox take 8,5MB and 4-char-substring+255-char-full-word Squat indexes take 11MB. So this doesn't look very promising.

[Dovecot] Configuration Error
by Mike McGonagle 26 Nov '07

26 Nov '07

Hello, I am a newbie when it comes to Dovecot, and in following this ( http://workaround.org/articles/ispmail-etch/ ) document in setting these things up, I have run into an error that I am not quite certain what to do... I am running Ubuntu Gutsy Gibbon, and using 1.0.5 for Dovecot. The message I am getting when I try to 'restart' Dovecot (using '/etc/init.d/dovecot restart') is: Error: Error in configuration file /etc/dovecot/dovecot.conf line 505: Protocol section not allowed here (section changed at line 505) Fatal: Invalid configuration in /etc/dovecot/dovecot.conf ...fail! Does this mean that I need to move this section of the configuration file to a different spot in the file? All I did was uncomment these things, and make the changes described in the link above, I would think that because this is just an edited version of the configuration file, that something like this shouldn't happen. Any help would be appreciated. Thank you, Mike -- Peace may sound simple—one beautiful word— but it requires everything we have, every quality, every strength, every dream, every high ideal. —Yehudi Menuhin (1916–1999), musician

[Dovecot] dspam integration
by Eugene Prokopiev 24 Nov '07

24 Nov '07

Hi, I see http://johannes.sipsolutions.net/Projects/dovecot-antispam and http://blog.cynapses.org/2007/09/13/dovecot-dspam-plugin/ solutions. Second git repo is not answer, first one is cloned, but I see some drawbacks with it. Dspam backend is more native solution but libdspam using instead of dspam external binary looks like preffered way to integrate dspam. Another problem is waiting for dspam child process exit, so IMAP session is blocked. Why not to fork and forget dspam child process? Email sender backend is non-blocking, but using MTA is great overhead. Calling external program with some args and mail body via pipe can be more suitable way, so external program may be dspam binary directly or shell/perl/python filter to any antispam engine via sendmail or something else. Has anybody plans to implement this features or it will be better to try it myself?

[Dovecot] Weirdness and Questions...
by James 24 Nov '07

24 Nov '07

version 1.0.7 OK, so here is my weirdness. I sent mail to the server from the command line. mail username@localhost < /etc/passwd When I open /var/spool/mail/username I can see 2 messages. The "system" message at the top and the the message produced from my command line email. If I HUP the process that runs xinet.d and re-open the users mail spool the 2nd email disappears which I wouldn't expect. Has anyone seen this before. My SMTP server could be EXIM or Sendmail. My co- admin is in the process from switching over from to EXIM. I am not sure if the SMTP server has anything to do with it or not. I can see the contents of all the email in ~/mail which is rsynced from my old server so that seems to be working properly. I have mail_locatiion in my config file, do I need anything else? mail_location = mbox:~/mail:INBOX=/var/spool/mail/%u In my list of mailboxes that are in ~/mail I see 2 folders that I'd rather not see. There .customeflags and .INBOX Anyway to hide these, as they are not needed in my opinion. Thanks, James

[Dovecot] Broken system.
by Marcelo Iturbe 22 Nov '07

22 Nov '07

Hello, I had an Inbox with 975,604 emails on ext3 filesystem. I keept getting dropped on the comand "copy 1:2000 inbox2", the syslog gave me an error message indicating "out of memory" problems. This despite the fact that the server has 800MB of ram free. Anyways, I asked if I could manuanlly move the files at the filesystem level or if that would mess up dovecot (break the GUIDs etc). I was informed that dovecot does not use GUIDs and that I could go ahead and move the emails at the shell level. So I did that, now the /cur folder only has 40,000 emails, but when I connect to the account via telnet, I still get the following: telnet localhost 143 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. * OK Dovecot ready. 110 login somelameuser somelamepass 110 OK Logged in. 111 select inbox * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 975604 EXISTS * 0 RECENT * OK [UNSEEN 1] First unseen. * OK [UIDVALIDITY 1188426666] UIDs valid * OK [UIDNEXT 979500] Predicted next UID 111 OK [READ-WRITE] Select completed. So even though there are only 40,000 emails in /cur, dovecot still thinks that there are 9756304 emails. How can I fix this? Thanks Marcelo

[Dovecot] dovecot loading during boot
by Robert W Nocella 22 Nov '07

22 Nov '07

I have two RHEL4 email servers running postfix/MailScanner which use dovecot. They work great. But during bootup the nfslock script in my init.d loads rpc.statd and calls portmap to get a port number. Portmap keeps giving rpc.statd the imaps port number (993). I then have to stop my mail server services, manually start dovecot, then restart the mail server services and everything goes merrily on its way. Stopping the mail server services drops rpc.statd from using port 993(according to netstat -tlnp). This allows dovecot to take it by default. How to I reserve imap and imaps ports exclusively for use by dovecot. The imap and imaps ports are listed in /etc/services. Thanks for any insight. -- Robert W Nocella Systems Analyst III Computer Support Group Manager UNM ECE Department UNM SOE IT Agent

[Dovecot] Getting two mails.....

When I receive a mail that is addressed to my email address and also with a cc to a mailinglist I subscribe to, I get two mails, which I guess is expected... But I have just moved to Dovecot from Cyrus, and Cyrus seems to know that this is the same mail, so only one of those two mail is stored on the imap srv...

[Dovecot] pop3_lock_session and NFS
by salimlist＠sdv.fr 22 Nov '07

22 Nov '07

Hello, I need an advice about POP3 and NFS with Dovecot 1.0 (as 1.1 is still tagged beta) . I currently have all messages and indexes under a NFS partition . I thus turned cache off using actimeo=0 . Of course, my current architecture does not allow me to keep the same user on the same dovecot server. Now, I have some NFS issues with high percentages of getattr() . If I understood well, the cache must be disabled, because of the case of 2 differents computers could log on the same time and mess up the index file . If I use the directive pop3_lock_session and enable it, that should block conccurent pop3 access using a lock file . Can I consider it safe enough to turn on the NFS cache (ie removing actimeo=0) ? Thanks in advance Salim Ps: For you info, we use dovecot here for a big cable broadband ISP, with 2,000,000 mailboxes using 30 dovecot POP3 servers,10 dovecot proxy servers and we are really happy with your nice software, we expect a lot from 1.1 .

[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

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';

Before dovecot I'm using # charter to mark public folders. So if I want set prefix = # its of course won't work, I tried using \# combination without luck. Is this possible anyway?

[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
