[Dovecot] Sylpheed-claws and virtual mailboxes
by Thomas Berker 27 Jul '09

27 Jul '09

Hi! Has someone encountered the following problem? What am I doing wrong or does someone know a workaround? Dovecot 1.2.1 on Debian unstable, two namespaces: namespace private { prefix = location = maildir:~/res/Maildir:LAYOUT=fs inbox = yes list = yes } namespace private { prefix = gtd/ separator = / list = yes location = virtual:~/res/Maildir/gtd:LAYOUT=fs:INBOX=~/res/Maildir/gtd } The problem: cur, tmp, new maildir folders get created within the folder gtd when it is opened by Sylpheed-claws (3.7.1). Subfolders in gtd holding the dovecot-virtual files are not recognised as mail folders at all, they show up but do nothing. Other clients (I have tested thunderbird, evolution) work as expected: they show the folder gtd and the sub-folders perform searches. Thanks in advance, tb

[Dovecot] Problems with ioloop on MacOS
by David Abrahams 27 Jul '09

27 Jul '09

I've been using the macports version of dovecot, which is 1.1.11, on MacOS 10.5.6 $ /opt/local/sbin/dovecot --exec-mail imap Fatal: kevent(EV_ADD, 0) failed: Operation not supported This version is configured --with-ioloop=kqueue The problem seems to be known, if not understood: http://lists.apple.com/archives/Darwin-userlevel/2008/Dec/msg00010.html However, if I use --with-ioloop=poll, I eventually get IMAP(dave): [9079]: invalid I/O fd 0, callback 0x9330 (not from the above command; it's a little later when Gnus tries to interact with dovecot through the shell) I've been unable to build/install any later versions of dovecot on MacOS. autogen.sh fails like this: ... glibtoolize: putting auxiliary files in `.'. glibtoolize: copying file `./ltmain.sh' glibtoolize: Consider adding `AC_CONFIG_MACRO_DIR([m4])' to configure.in and glibtoolize: rerunning glibtoolize, to keep the correct libtool macros in-tree. glibtoolize: Consider adding `-I m4' to ACLOCAL_AMFLAGS in Makefile.am. configure.in:281: installing `./config.guess' configure.in:282: required file `./config.rpath' not found configure.in:281: installing `./config.sub' configure.in:5: installing `./install-sh' configure.in:5: installing `./missing' src/auth/Makefile.am: installing `./depcomp' autoreconf: automake failed with exit status: 1 -- Dave Abrahams BoostPro Computing http://www.boostpro.com

[Dovecot] [BUG] Incorrect maildir quota value after maildirsize creation
by Adam Osuchowski 27 Jul '09

27 Jul '09

I found a problem with maildir++ quota. When dovecot creates maildirsize file, it counts quota wrong. This is, how I reproduce a situation on version 1.2.0: First, I remove maildirsize file: # cd /var/mail/test # rm -f maildirsize # ls -la total 32 drwx--S--- 5 mbox mbox 4096 Jul 12 20:45 . drwxrwsr-x 3 root mbox 4096 Jul 12 20:39 .. drwx--S--- 2 mbox mbox 4096 Jul 9 20:45 cur -rw------- 1 mbox mbox 491 Jul 12 20:45 dovecot-uidlist -rw------- 1 mbox mbox 8 Jul 12 20:45 dovecot-uidvalidity -rw------- 1 mbox mbox 8536 Jul 12 20:45 dovecot.index.cache -rw------- 1 mbox mbox 284 Jul 12 20:45 dovecot.index.log drwx--S--- 2 mbox mbox 4096 Jul 12 00:58 new drwx--S--- 2 mbox mbox 4096 Jul 12 00:58 tmp I have 8 emails which take 14183471 bytes together: # find cur new -type f | wc -l 8 # find cur new -type f -printf '%s\n' | awk 'END { print a } { a += $0 }' 14183471 Now, I connect to dovecot via POP3 and delete exactly _one_ email which takes 969 bytes. After that, maildirsize file has been created: # ls -la total 48 drwx--S--- 5 mbox mbox 4096 Jul 12 20:50 . drwxrwsr-x 3 root mbox 4096 Jul 12 20:39 .. drwx--S--- 2 mbox mbox 4096 Jul 12 20:50 cur -rw------- 1 mbox mbox 491 Jul 12 20:45 dovecot-uidlist -rw------- 1 mbox mbox 8 Jul 12 20:45 dovecot-uidvalidity -rw------- 1 mbox mbox 8536 Jul 12 20:50 dovecot.index.cache -rw------- 1 mbox mbox 532 Jul 12 20:50 dovecot.index.log -rw------- 1 mbox mbox 28 Jul 12 20:50 maildirsize drwx--S--- 2 mbox mbox 4096 Jul 9 00:58 new drwx--S--- 2 mbox mbox 4096 Jul 9 00:58 tmp # cat maildirsize 5242880S 14182502 7 -969 -1 So, maildirsize says, that there should be 7-1=6 emails which should take 14182502-969=14181533 bytes together. In fact, there are 7 emails (I delete only one of eight emails) which take 14182502 bytes together (deleted email taked 969 bytes): # find cur new -type f | wc -l 7 # find cur new -type f -printf '%s\n' | awk 'END { print a } { a += $0 }' 14182502 I figured, that dovecot after physically file removal, calls function maildir_quota_update(), which calls maildirquota_refresh() first (which in turn recalculate quota with new values), and then calls maildirsize_update(), which additionally and incorrectly decreases quota value. Regards, Adam.

I'm using the mysql program supported Dovecot but ? have a problem about qoution so I would like to put user specific quota. Would you like to send me necessary settings. dovecot-sql.conf file would be? Please send conf dovecot-sql.conf ? dovecot 1.1.13 dovecot.conf file dict { quotadict = mysql:/etc/dovecot/dict-quota.conf } plugin { quota = dict:user::proxy::quotadict quota_rule = *:storage=200M:messages=10000 quota_rule2 = Trash:storage=100M quota_warning = storage=95%% /usr/local/bin/quota-warning.sh 95 quota_warning2 = storage=80%% /usr/local/bin/quota-warning.sh 80 } Thanks for your feedback.

[Dovecot] [PATCH] include parameters can handle globbing
by Thomas GUTHMANN 27 Jul '09

27 Jul '09

Hey guys, This patch will allow you to include different configuration files in the main dovecot.conf by using globbing [1] (like Apache for instance). !include = conf.d/*.conf !include_try = /etc/dovecot/extra* So with this you can split the dovecot.conf in different smaller configuration files. It's more the debian way to do that. But it's very handy if you have to generate dynamically parts of dovecot.conf based on a centralized main configuration (imagine you have 10 servers and you want to change the default quota for instance, do a script which update that based on the data contained in SQL/LDAP/XML/whatever). I designed this for my personal use with dovecot 1.2.1. It does the job. But I warn you :) My code may hurt your eyes. If so either close them or improve/fix my code or ... "Hare Krishna" [2] :) The include features has been done and almost kept hidden by Timo :) I've just add the globbing feature to !include and !include_try. The patch will modify - src/lib-settings/settings.c - dovecot-example.conf $ cd dovecot-1.2.1 $ patch -p1 < includepatch.diff It has been test with GNU/Linux Debian dunno if it compiles on FreeBSD/AIX/MacOSX but everything is POSIX compliant so... it should :) Cheers, Thomas [1]: Thanks Aria for the tip about the glob() function. It's cleaner. [2]: Rumor has it that Hare Krishna means hire a consultant in Hindi.

I'm try to build additional 2 private namespaces namespace private { prefix = 1/ #location = ~/mail/1 list = yes subscriptions = yes } namespace private { prefix = 2/ #location = ~/mail/2 list = yes subscriptions = yes } First private namespace contains inbox and mail_location not defined (selects in sql query in userdb). Is dovecot have variable which contains current mail_location like current home? And if i have location = ~/mail/2 and subscrive to namespace in my mail client - i have error like mailbox does not exists. Where i must create folder fo what namespace? in ~/mail or ~/mail/mailboxes? Thank You. -- Vasiliy Tolstov <v.tolstov(a)selfip.ru> Selfip.Ru

[Dovecot] Newbie: unable to access mailbox more than once
by Matt Petoe 27 Jul '09

27 Jul '09

Hello, I'm using dovecot as a mail relay so that I can back up my providers IMAP mail locally. I'm impressed how easy this was to set up, but I'm having a quirk that I would like help with, if possible. There are many weak links in my set-up chain, if you will, but I think I've narrowed the problem. I'll describe my set-up anyway. I'm running dovecot 1.1.4 on ubuntu 8.10. I have a shared NAS drive running a NFS server. I have chosen to store the .indexes and .control directories on the NAS also, since I want a set-up that will remain backed up and easily replicated if I (accidentally) erase the ubuntu install in the future. I'm using imapsync to copy messages from my email provider. It works once only, and subsequent attempts seem to hang when accessing any local dovecot mailbox folders that were changed last time. I have succeeded in using Thunderbird to access the dovecot mailboxes once. I know the paths are being found, because I can 'list' mailboxes when I telnet locally: b list "" * * LIST (\HasNoChildren) "." "Trash" * LIST (\HasNoChildren) "." "Drafts" * LIST (\HasNoChildren) "." "indexes" * LIST (\HasNoChildren) "." "control" * LIST (\HasNoChildren) "." "Junk" * LIST (\HasNoChildren) "." "Sent" * LIST (\HasNoChildren) "." "INBOX" * LIST (\HasNoChildren) "." "Trash-1000" b OK List completed. However, a 'select' command will only work for empty folders (such as .Trash). If I try to select a full folder such as ".Sent" then the process just hangs. The logs don't mention anything interesting, even though I have enabled debug_on and auth_debug. However, I attached a trace to the 'imap' process and got something interesting. I think maybe the lock process is failing for some reason? Here's a snip of the failure when selecting the .Sent folder: 12:00:21.190011 gettimeofday({1248141621, 190099}, NULL) = 0 12:00:21.190503 read(0, "f select Sent\r\n", 4034) = 15 12:00:21.190906 stat64("/mnt/Mail/.Sent/tmp", {st_mode=S_IFDIR|0700, st_size=4096, ...}) = 0 12:00:21.241561 stat64("/mnt/Mail/.indexes/.Sent", {st_mode=S_IFDIR|0700, st_size=4096, ...}) = 0 12:00:21.248325 stat64("/mnt/Mail/.Sent/dovecot-shared", 0xbf86c6c8) = -1 ENOENT (No such file or directory) 12:00:21.248847 time(NULL) = 1248141621 12:00:21.249060 open("/mnt/Mail/.indexes/.Sent/dovecot.index.log", O_RDWR|O_LARGEFILE) = 7 12:00:21.286953 fstat64(7, {st_mode=S_IFREG|0600, st_size=26472, ...}) = 0 12:00:21.287423 pread64(7, "\1\0\30\0\264:dJ\4\0\0\0\3\0\0\0\\\200\0\0\374?dJ", 24, 0) = 24 12:00:21.287696 stat64("/mnt/Mail/.indexes/.Sent/dovecot.index.log.2", 0xbf86c5ac) = -1 ENOENT (No such file or directory) 12:00:21.288070 open("/mnt/Mail/.indexes/.Sent/dovecot.index.log.2", O_RDWR|O_LARGEFILE) = -1 ENOENT (No such file or directory) 12:00:21.288614 open("/mnt/Mail/.indexes/.Sent/dovecot.index", O_RDWR|O_LARGEFILE) = 9 12:00:21.296814 alarm(60) = 0 12:00:21.297181 fcntl64(9, F_SETLKW64, {type=F_RDLCK, whence=SEEK_SET, start=0, len=0} I have set the locks to dotlock_try followed by fcntl. The trace above seemed to fail with the dotlock, and proceed to fcntl? Here is the output from dovecot -n # 1.1.4: /etc/dovecot/dovecot.conf log_path: /var/log/dovecot.log log_timestamp: %Y-%m-%d %H:%M:%S login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login login_greeting_capability: yes mail_max_userip_connections: 0 mail_privileged_group: mail mail_location: maildir:/mnt/Mail:INBOX=/mnt/Mail/.INBOX:INDEX=/mnt/Mail/.indexes/:CONTROL=/mnt/Mail/.control mail_debug: yes mail_full_filesystem_access: yes mmap_disable: yes dotlock_use_excl: no mail_nfs_storage: yes mail_nfs_index: yes lock_method: dotlock maildir_stat_dirs: yes mbox_read_locks: dotlock_try fcntl mbox_write_locks: dotlock_try fcntl imap_client_workarounds: tb-extra-mailbox-sep auth default: verbose: yes debug: yes passdb: driver: pam userdb: driver: passwd Sorry if this is a long post. The summary, I guess, is that I can't access mailbox folders with emails inside. I'm very new at all this, and only got this far from the excellent wiki. But now I'm stumped. Thanks heaps, Matt P

[Dovecot] lazy expunge - how to unset deleted imap flag
by Colo Colo 27 Jul '09

27 Jul '09

Hello, I am using dovecot 1.1.13 in debian lenny with exim4 and I have Outlook 2007 clients. I have configured lazy expunge plugin. User marks messages in INBOX for deletion then click "delete messages from server" then the messages are moved to .EXPUNGED folder which is correct but they are still marked with IMAP deleted flag which is bad cause when user marks another messages in INBOX for deletion and click again on "delete messages from server" the messages which were in .EXPUNGE are gone forever. Is there any possibility to change this behavior i.e. instead from: move messages tagged for deletion to .EXPUNGE folder to: move messages tagged for deletion to .EXPUNGE folder and UNSET deleted flag ? Thanx
