[Dovecot] squirrelmail doesn't display share
by Eric Broch 05 Apr '11

05 Apr '11

Hello list, I have dovecot 2.0.11 installed on a client's server and Squirrelmail as the webmail client. I created the share below in dovecot.conf and it appears in Thunderbird and Outlook but not in Squirrelmail. What setting do I need to adjust in order for the share to appear in squirrelmail? Below are dumps of /etc/dovecot.conf and /etc/squirrelmail/local_config.conf # dovecot -n # 2.0.11: /etc/dovecot/dovecot.conf # OS: Linux 2.6.18-194.32.1.el5 i686 CentOS release 5.5 (Final) auth_cache_size = 32 M auth_mechanisms = plain login digest-md5 cram-md5 auth_username_format = %Lu disable_plaintext_auth = no first_valid_uid = 89 log_path = /var/log/dovecot.log login_greeting = Dovecot toaster ready. namespace { inbox = yes location = prefix = INBOX. separator = . type = private } namespace { location = maildir:/home/vpopmail/domains/mydomain.com/shared/projects prefix = projects. separator = . type = shared } passdb { args = cache_key=%u webmail=127.0.0.1 driver = vpopmail } plugin/quota = maildir protocols = imap ssl_cert = </var/qmail/control/servercert.pem ssl_key = </var/qmail/control/servercert.pem userdb { args = cache_key=%u quota_template=quota_rule=*:backend=%q driver = vpopmail } protocol imap { imap_client_workarounds = delay-newmail } # cat config_local.php <?php #################### # Local configuration for Qmail Toaster # configure to suit your requirements $hide_sm_attributions = true; $useSendmail = false; $imap_server_type = 'courier'; $optional_delimiter = '.'; $default_folder_prefix = 'INBOX.'; $show_prefix_option = false; $show_contain_subfolders_option = false; $delete_folder = true; $plugins[] = 'calendar'; $plugins[] = 'notes'; $plugins[] = 'filters'; $plugins[] = 'quota_usage'; $plugins[] = 'unsafe_image_rules'; $plugins[] = 'qmailadmin_login'; ?>

[Dovecot] imap-login: Panic: file ioloop.c: line 35 (io_add): assertion failed:
by Jan-Frode Myklebust 05 Apr '11

05 Apr '11

My dovecot directors (v2.0.8) had 3 instances of these yesterday: imap-login: Panic: file ioloop.c: line 35 (io_add): assertion failed: (fd >= 0) master: Error: service(imap-login): child 17374 killed with signal 6 (core dumps disabled) imap-login: Panic: file ioloop.c: line 35 (io_add): assertion failed: (fd >= 0) master: Error: service(imap-login): child 1780 killed with signal 6 (core dumps disabled) imap-login: Panic: file ioloop.c: line 35 (io_add): assertion failed: (fd >= 0) master: Error: service(imap-login): child 10349 killed with signal 6 (core dumps disabled) dovecot "assertion failed" normally scares me quite a bit, but I don't think this can be very bad, since it's only on the directors and we're not doing lmtp here yet.. More of a FYI, and please let me know if I should enable something to get better debug data if/when it happens again. -jf

[Dovecot] Master credentials for sieve
by Edgar Fuß 05 Apr '11

05 Apr '11

Is there a method for using master credentials for sieve only? We sometimes need to install/edit sieve script for some of our users. Currently, we just edit the files on the file server, but that doesn't appear the most sensible way for me

[Dovecot] Invalid old index files
by Reinhard Vicinus 05 Apr '11

05 Apr '11

Hi, i'm in the process of evaluating dovecot. I have a rather big testing environment with four dovecot director frontend instances and four dovecot backend instances. Mailboxes are all in mdbox format and stored on nfs. Indexes are stored locally. dovecot nfs setup for high performance is used (mmap_disable = no, dotlock_use_excl = yes, mail_nfs_storage = yes, mail_nfs_index = no). The remaining problem is, if i disable a backend server and the backend server which took over the connection already has some old index files, this index files aren't updated. If there aren't any index files all is fine and the index files are created anew. I can solve this by regularly deleting old index files via a cronjob. But i'm not sure if i made a configuration mistake and dovecot somehow can detect old index files automatically and invalidate them? Thanks in advance Reinhard

by Igor Zinovik 05 Apr '11

Hello. I'm migrating from cyrus to dovecot and now after i converted mailboxes to Maildir. Some users already has imap folders with cyrillic chars. How could i autocreate folders with cyrillic chars? When i type something like: ... autocreate = utf8_chars autosubscribe = utf8_chars ... In logs i see that dovecot complains: Apr 05 16:21:43 imap(pavelkor): Debug: autocreate: Failed to create mailbox utf8_chars: Invalid mailbox name It is even possible to achieve?

[Dovecot] Dsync & random delete problem
by Antoine Millet 04 Apr '11

04 Apr '11

Hello, I've updated my home mail server with dovecot 2.0.11 with idea of using dsync to synchronize two master servers (one at home behind an ADSL connection, and another in a DC with a gigabit connection). Dsync is launched every minutes by a cron job for each hosted mailboxes (in Maildir format). Obviously, a lock prevents to launch more than one dsync process at time. On a test mailbox, it worked perfectly, but when I decided to use it on my own mailbox: big drama :-). Some trashed messages reappear after the next sync, by dint of insisting, sometime it are duplicated. Occasionally, the synchronization has the desired effect, but messages reappear few hours later... So, my questions are: * Dsync is it supposed to be used to synchronize two mailboxes on continuously? * Are these problems known? I've found one thread about a random delete problem, so it seem to be? Do you need more informations to debug it? My informations: * Dovecot version: 2.0.11 * Distro: Debian Squeeze amd64 * FS: ext4 * Mailbox format: Maildir * Dsync command: "dsync -u {account} mirror ssh -i /var/vmail/sync/id_vmail -C {dest} dsync -u {account}" * Bug happen randomly, I haven't found a way to reproduce it. * Dovecot configuration: A part in particular is interesting? Thanks in advance, -- Antoine Millet http://inaps.org

[Dovecot] doveadm mailbox status - getting the size in bytes
by Patrick McLean 04 Apr '11

04 Apr '11

Hi, doveadm has an option to get the "vsize" of mailboxes, which is calculated by counting the number of linefeeds, but there does not appear to be way to simply get the size in bytes of a mailbox. I was wondering if there is something I am missing (I am using mdbox), or if not is it possible to implement this. Thanks

[Dovecot] dovecot ldap failed to recover
by Jan-Frode Myklebust 04 Apr '11

04 Apr '11

One of our backend pop/imap-server running dovecot v1.2.16 experienced some problems yesterday. It suddenly couldn't authenticate users anymore, flooding the logs with: pop3-login: Disconnected (auth failed, 1 attempts): user=<user1(a)example.com>, method=PLAIN, rip=192.168.42.15, lip=192.168.42.28 The problem seemed to start with this log entry: Mar 29 18:57:21 popimap1 dovecot: auth(default): ldap(userX(a)example.com,192.168.42.15): Connection appears to be hanging, reconnecting and this suspicious entry a few seconds later: Mar 29 18:57:41 popimap1 dovecot: auth(default): LDAP: Reply with unknown msgid 2 Afterward 18:57:21 it was unable to authenticate any users before I restarted the dovecot service. Also some of our postfix servers reported ldap lookup failures between 18:56-18:58, but then recovered. Looking at the ldap server side, we saw no problems logged, but netstat reports there being 3 active ldap sessions towards the dovecot server that failed yesterday, while the dovecot server only has 1: ldap1$ netstat -na |grep 192.168.42.28 tcp 0 0 192.168.43.2:389 192.168.42.28:44408 ESTABLISHED tcp 0 0 192.168.43.2:389 192.168.42.28:36464 ESTABLISHED tcp 0 0 192.168.43.2:389 192.168.42.28:60580 ESTABLISHED popimap1$ netstat -na| grep 192.168.43.2 tcp 0 0 192.168.42.28:60580 192.168.43.2:389 ESTABLISHED So it looks to us like there was some problem with either the network, or the ldap-server for a short periode, and that dovecot then wasn't able to recover from this. -jf

Dear list, I'm trying to build a dovecot-2.0.11 package for our systems, and so I would like to install it to a temporary directory. But when I use "gmake DESTDIR=/tmp/build install", instead of binaries, it's wrapper scripts that get installed for dovecot, doveconf and doveadm. When I install to the default location all is well. Does anybody know how how to install to a temp location? Thanks in advance for your answer! Best regards, Gerard Ranke

[Dovecot] Segmentation fault with vpopmail auth
by Samuel Montosa 04 Apr '11

04 Apr '11

Hi. I am new in the list. First, excuse my english. I am not native speaker. A few hours ago I had a problem with process dovecot-auth and vpopmail. Versions I had using, working, were: vpopmail 5.4.28 dovecot-1.1.12 I tried to compile dovecot-1.2.16. Compilation was well but in execution system said: kernel: dovecot-auth[2842]: segfault at 645f20 ip 0000000000645f20 sp 00007fff69bd3708 error 15 in dovecot-auth[645000+1000] and so. Then, I tried to recompile dovecot-1.1.12 (original version I had working) but system said the same. After investigation, I saw I had mixed of vpopmail versions. Problem was I had /home/vpopmail/lib/libvpopmail.so in my system. When this file is present, compilation of dovecot link dovocot-auth to dynamic library libvpopmail.so, but it is not necessary since I had my system working using vpopmail without this .so. What I recommend is to compile a fresh vpopmail. Now I am using vpopmail-5.4.32 (at now, stable version) and dovecot-1.2.16. First, compile vpopmail and make sure you purge /home/vpopmail/lib/ of libvpopmail.so. Fresh installations of vpopmail, from tar.gz (not from SVN) _doesn't_ build libvpopmail.so, so make sure this file doesn't exist before you compile dovecot. For me, library dependencies are: mymachine:/usr/local/src/dovecot-1.2.16# ldd src/auth/dovecot-auth linux-vdso.so.1 => (0x00007fff63df5000) libpam.so.0 => /lib/libpam.so.0 (0x00007f9f925e1000) libcrypt.so.1 => /lib/libcrypt.so.1 (0x00007f9f923aa000) libdl.so.2 => /lib/libdl.so.2 (0x00007f9f921a5000) librt.so.1 => /lib/librt.so.1 (0x00007f9f91f9d000) libc.so.6 => /lib/libc.so.6 (0x00007f9f91c3c000) /lib64/ld-linux-x86-64.so.2 (0x00007f9f927f7000) libpthread.so.0 => /lib/libpthread.so.0 (0x00007f9f91a1f000) I hope this helps. It was a strange "bug". Regards. -- Samuel Montosa

[Dovecot] Maildir
by Walt Shekrota 01 Apr '11

01 Apr '11

I noticed in Cyrus they seem to address maildir++ recognised by IMAP. I need to know does Dovecot recognise this format? Procmail has an ability to deliver mails to different folders which if unrecognised renders the whole process useless. Does Dovecot have a similar deliver method? Thanks. -Walt

[Dovecot] inotify and network/cluster filesystems
by Jan-Frode Myklebust 01 Apr '11

01 Apr '11

(dovecot v1.2.16) I've notice the log notices about increasing /proc/sys/fs/inotify/max_user_instances on my servers, and started wondering if inotify works for network/cluster filesystems.. I found this: http://www.ibm.com/developerworks/forums/thread.jspa?threadID=311194 which says that there's no mechanism for one node to tell another node that a directory changed for GPFS.. And I would assume the same applies for NFS and other network filesystems. (Yes I know, we should use director to make users sticky to one host -- but we're not yet ready for that for lmtp). So, are there any recommendations for what settings one should use for for filesystems where inotify woun't work ? Are there settings for disabling it (without recompiling)? And does mailbox_idle_check_interval happen in addition to inotify, so that clients will be notified even with a broken inotify ? -jf

Hello, I've upgraded from dovecot 1.2.x with sieve to dovecot 2.0.11 with sieve. I've noticed that folders are no more created at delivery time now. I've read that I have to do two things: lda_mailbox_autocreate = yes in dovecot.conf and fileinto :create in the sieve script.

[Dovecot] Mail_location and formats
by Walt Shekrota 31 Mar '11

31 Mar '11

Hi, Ok I know that the Maildir hierarchical structure works because I saw it intermittantly in my setup. At times I could look at ALL folders in my client. mail_location = maildir:~/Maildir:LAYOUT=fs http://wiki1.dovecot.org/MailLocation/Maildir this says 1.1 only? My maildir folder has a collection of maildir folders ie each has cur new tmp folders. As an experiment I took the cur new tmp out of my INBOX folder and put it in the root of Maildir. This worked with dovecot using the inbox only or the standard maildir++ format. Although it would not see the old mail in the folder not sure why. mail_location = maildir:~/Maildir This setup also ignores the remainder of folders. I know the dovecot support of maildir is shakey due to standards compliance but this is crazy ... and unusable. Does ANYONE have a working maildir setup in the hierarchical layout? Maildir/ inbox mail-sent outbox otherfolder Fred Sue Thanks. -Walt

[Dovecot] POP3 connection issue & SASL not compiled in
by sunhux G 31 Mar '11

31 Mar '11

After I've configured dovecot for SSL according to the info given in the link below: https://access.redhat.com/kb/docs/DOC-6671 (tried both POP3 & secure POP3 & got the same result) I tested POP3 access from my unblocked (no firewall rule for outgoing) broadband PC's Outlook to connect to the postfix/dovecot server & got the following : Tasks Status ===================== ======== Establish network connection Completed Find outgoing mail server (SMTP) Completed Find incoming mail server (POP3) Completed Log onto incoming mail server (PO... Send test e-mail message Completed (yep, this email was received in postfix mailbox) & seconds later, the following messages returned: Log onto incoming mail server (POP3): The specified server was found, but there was no response from the server. Please verify that the port and SSL information is correct. To access these settings close this dialog, then click More Settings and click on the Advanced tab. Find incoming mail server (POP3): Outlook could not connect to the incoming mail server (POP3). The problem could be the server name or port, or your server may not support SSL. Verify your port and SSL settings in More Settings under the Advanced tab. Q1: What do I need to provide to this list for further troubleshooting? Q2: I have the following log entry in /var/log/mailog : Mar 31 10:48:36 hostname postfix/smtpd[22258]: warning: smtpd_sasl_auth_enable is true, but SASL support is not compiled in Is this related to my POP3 connection issue?

[Dovecot] How to grant a kerberos ticket after successful imap authentication from dovecot
by André Rodier 31 Mar '11

31 Mar '11

Hello everybody, I hope this question is appropriate for this list. Apologies if not. I am running a set of virtual machines under debian 6, to build a mail/collaboration server. I am mainly using dovecot, postfix, openldap and heimdal. Mails are stored using maildir, on a NFSv4 share. My users are system users, but using LDAP and libpam-ldap and libnss-ldap for caching credentials information. Everything is working as expected, well, /almost/. Since NFS is using kerberos, by defaults, my users are not able to access their mail storage if they have not received their kerberos ticket. For instance, if I do nothing, this is the errors I have from dovecot when trying to logon using any imap client: Mar 31 09:33:07 titan dovecot: imap-login: Login: user=, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Mar 31 09:33:07 titan dovecot: dovecot: Fatal: chdir(/home/emails/team/arodier/) failed: Permission denied (euid=1003(arodier) egid=1001(red2team) missing +x perm: /home/emails) Mar 31 09:33:07 titan dovecot: dovecot: child 5089 (imap) returned error 89 (Fatal failure) However, if I just login on a console for the user "/arodier/", I see that I have received a ticket, and I can see it with klist: Credentials cache: FILE:/tmp/krb5cc_1001_ywvktf Principal: arodier(a)RED2.SRV Issued Expires Principal Mar 31 09:25:55 Mar 31 19:25:53 krbtgt/RED2.SRV(a)RED2.SRV Mar 31 09:25:57 Mar 31 19:25:53 nfs/ananke.red2.srv(a)RED2.SRV Once I have simply logged myself on a console, I can access my emails using any IMAP client. The question is: How should I configure libpam (or dovecot ?) to initialise/receive a kerberos ticket after successful authentication ? Thanks for your answers.

No '.'s just folders. something like Maildir/ INBOX mail-sent outbox other where each has cur new and tmp folders. if I access this directory with IMAP it creates cur new and tmp in the root. ie Maildir/ INBOX cur new tmp mail-sent outbox other This implies to me 1. it finds the Maildir directory 2. it apparently does not have access to the directories like INBOX so it makes its own in the root? or is this a side effect I'm misunderstanding? The resulting IMAP session shows an empty INBOX only (this must be the cur new tmp it added) The real INBOX is not accessible but still intact. In a session this morning I could access all the folders just not the real INBOX. INBOX was as is here empty with cur new tmp in the root of the Maildir folder. This behavior makes no sense. I'm using the hierarchical structure as pointed to in. http://wiki1.dovecot.org/MailLocation/Maildir It appears my grief surrounds dovecot's detection of mailbox. This is kind of what I said days ago. Setting up requires you to know expected states. Something in my environmment I haven't been able to identify (yet) is influencing recognising that hierarchical maildir structure. -Walt

Hi, small question: Will the WiKi of the version 2 be updated shortly? Many things are not right at all. This would be really very nice. Many thanks in advance. -- Mit freundlichen Grüßen, Jim Knuth P.S.: Bitte senden Sie KEINE HTML-Mails! Zufallszitat: Das Schweigen von gestern rechtfertigt nie das Schweigen von heute. (Otto Schily)

[Dovecot] Message file prefetching to memory
by Timo Sirainen 31 Mar '11

31 Mar '11

I added a new mail_prefetch_count setting to Dovecot v2.1 (http://hg.dovecot.org/dovecot-2.1/) Its main purpose is to avoid unnecessary latency while waiting for replies from remote server with imapc, i.e. instead of doing (FETCH, wait, FETCH, wait, ...) it can do (FETCH, FETCH, .., wait). For the same reason it's also going to be very useful once I add support for key-value databases / other high latency cloud filesystems. It also works with Maildir, single-dbox and cydir backends by calling posix_fadvise(POSIX_FADV_WILLNEED) for the files. This syscall is apparently only implemented by Linux. It should tell the kernel to start reading the files from disk to page cache. By calling this for multiple files, it should help the kernel optimize disk I/O. For example if 10 files are prefetched, the kernel might figure out that it should read them in a different order to avoid extra disk seeks. Perhaps it also does something useful with NFS, I don't know. I'm not sure if it would be a good idea to use this for mbox or multi-dbox files, since they already have multiple messages in same file so kernel probably already did some prefetching. With mdbox I guess it could be useful if the message file changes.. This optimization currently works only for FETCH command (and POP3 RETR and TOP). SEARCH/THREAD/SORT commands will hopefully implement it soon also. I'd be interested in knowing what the effects of this setting are if anyone tests this some day.

[Dovecot] v1.2.12 and debug
by Walt Shekrota 30 Mar '11

30 Mar '11

Is there some kind of extended debug that might show why my maildir is not foundat login? It has worked off and on, once briefly today then no more. I'm going around twiddling knobs guessing at this point which is foolish. I need some real bread crumbs to indicate what is going wrong. I've tried all kinds of .conf file ... example file etc. I figured using the least number of settings should get me somewhere but I still have no luck. I'd love to just give up and load that PPA for 2.x but I have no idea what package to install in debian. (I have the PPA update) Thanks. -Walt

In 1.2.12 or there abouts how do changes in the dovecot.conf happen? After doing the sig HUP I have noted there is generally a delay in the recognition of items in my .conf. An example I had logging set off, turned it on and it was several restarts before I again saw logging? This delay is driving me nuts in trying to figure out what needs to change. Thanks. -Walt

[Dovecot] migrating to dovecot
by Alexandre Chapellon 30 Mar '11

30 Mar '11

Hello, I am trying to setup a migration scenario from an proprietary solution to dovecot IMAP/POP3. Whereas am only at the strating point, things appear quite complicated because of the following reasons: - The proprietary solution uses special/own/proprietary mailbox format (wich is more like maildir but is not maildir) - I don't have direct access to the filesystem where the mails are stored. The best I could do would be a snapshots of the filesystem - I have about 1,5TB of mail data. - Having users to be forced to empty their mailbox before migration or re-download their whole mailbox after migration would be something hard for me to present as a correct option. Am looking for advices that would avoid me loosing time searching in bad directions. Or even point me to a miraculous tool thatdoes all magic while i have a beer :) Best regards. -- horoa: la voie est libre

[Dovecot] file permissions
by Walt Shekrota 29 Mar '11

29 Mar '11

Dovecot 1.2.12 maildir format using :LAYOUT=fs (my Mail dir came from KDE) I can't remember the permissions of the /Mail/ directory because I haven't been concerned with it too much until now. I think they were user:user or user:mail. Now a new mail ends up 600 root:mail. (in alternate directories) When I start my mutt client to the imap server it gets an error for any folder containing a root:mail new mail file. I think the root ownership is a procmail side effect? If I chmod 760 Mail/folder/* (then the new emails show in dovecot without the access error) It appears mail comes to the INBOX fine just not individual folders On the initial access, dovecot gets a "missing +r perm" or "+x" in the log. 1: What permission structure should permeate my Mail dir? 2: What might affect the incoming mail file getting wrong permissions/ownership? I'm thinking the later may be a procmail issue unless it is related to initial incorrect permissions? Thanks for any insight. -Walt

[Dovecot] Trouble with password scheme module
by Ian R. Justman 29 Mar '11

29 Mar '11

Hi, all. About two and a half years ago, I wrote a hack to add an additional MD5-based password scheme to Dovecot, but I wrote it as a hack to src/auth/password_scheme.c since it was relatively easy to do, and I needed to get a machine running since the machine I was replacing, a Sun Ultra 5 running Post.Office, had dying hard drives. Now, I'm actually sitting down and adapting it as a module and am having trouble getting it to work. The code tarball itself can be picked up here: http://www.ian-justman.com/code/dovecot/password_scheme_po_smd5.tar.gz Before I continued, I made sure that a system-level account worked: # telnet <server IP> 110 Trying <server IP>... Connected to <server IP>. Escape character is '^]'. +OK Dovecot ready. user <username> +OK pass <password> +OK Logged in. quit +OK Logging out. Connection closed by foreign host. I then enabled the module, which introduces the password scheme "PO-SMD5". I have Dovecot's default scheme set to SMD5. If I get a password hash whose value has a {PO-SMD5} tag on it, the session looks like the following: # telnet <server IP> 110 Trying <server IP>... Connected to <server IP>. Escape character is '^]'. +OK Dovecot ready. user <user with PO-SMD5 password> +OK pass <user's password> -ERR Authentication failed. quit +OK Logging out Connection closed by foreign host. The following entry is deposited into the system log: Mar 28 17:44:51 <hostname> dovecot: auth: Error: sql(<username>,<server IP>): Unknown scheme PO-SMD5 However, when I try using an account covered by the system (which does work when the plugin isn't loaded in dovecot.conf), the session looks like the following: mikuru# telnet <server IP> 110 Trying <server IP>... Connected to <server IP>. Escape character is '^]'. +OK Dovecot ready. user <user with system password> +OK pass <user's password> Connection closed by foreign host. The following entry is deposited into the system log: Mar 28 17:45:13 <hostname> dovecot: pop3: Error: dlopen(/usr/local/lib/dovecot/lib_password_scheme_po_smd5.so) failed: /usr/local/lib/dovecot/lib_password_scheme_po_smd5.so: Undefined symbol "password_scheme_unregister" Otherwise, the patch I developed under 1.x applies cleanly to 2.0.x's password_scheme.c and works perfectly as a builtin. This work was done under FreeBSD 8.1-RELEASE amd64. Any ideas? --Ian. -- Ian R. Justman UNIX hacker. Anime fan. Any questions? ianj (at) ian-justman.com

[Dovecot] dovecot auth password mismatch
by david＠davidwbrown.name 28 Mar '11

Hello dovecot gods, after using Postfix with webmail for 8 years the new gen of email smartphones forces me to consider using IMAP. Actually, for several months I was successfully using IMAP. I believe the reason why IMAP worked previously (before migrating to the Cloud) the hosting server and the client machines were considered local by the system. Now, I have moved everything to a Cloud service. And, now attempts to use my Ubuntu Evolution or iPhone generates the following error condition in my logs: dovecot: auth(default): client in: AUTH 1 PLAIN service=imap lip=xxx.yyy.www.zzz rip=75.214.160.72 lport=143 rport=59107 resp=AGRhdmlkAGx1dGVmaXNr dovecot: auth(default): passwd(kilroy,75.214.160.72): lookup dovecot: auth(default): passwd(kilroy,75.214.160.72): Password mismatch dovecot: auth(default): passwd(kilroy,75.214.160.72): CRYPT(mypass) != 'x' dovecot: auth(default): new auth connection: pid=15522 dovecot: auth(default): client out: FAIL 1 user=kilroy ******************* dovecot -n ******************* 1.2.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.34.1-rscloud x86_64 Ubuntu 10.04.2 LTS log_timestamp: %Y-%m-%d %H:%M:%S disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login mail_privileged_group: mail mail_location: maildir:~/Maildir mbox_write_locks: fcntl dotlock auth default: realms: myname.name, hisname.name, hername.name default_realm: myrealm.com username_format: %n verbose: yes debug: yes debug_passwords: yes passdb: driver: passwd userdb: driver: passwd

[Dovecot] Errors logged from 2.0.11
by Andreas Kossack 28 Mar '11

28 Mar '11

Hi all, we use dovecot 2.0.11 with local (LDAP based) users and see (occasionally) error messages like "Mar 15 09:29:26 MailServ local3:err|error dovecot: imap(xxxx): Error: creat(/dovecot.mailbox.log) failed: Permission denied (euid=1985(xxxx) egid=219(yyyy) stat() failed: No such file or directory, euid is not dir owner) but all (filesystem) permissions are correct and the user doesn't report any errors. All works as expected. What can be the reason for such messages? -- Mit freundlichen Grüßen A.

[Dovecot] IMAP move extension support
by Nikolay Shopik 28 Mar '11

28 Mar '11

Hi Timo, Any chance we could get IMAP move extension support in Dovecot? http://tools.ietf.org/html/draft-krecicki-imap-move-01 This is now landed in Thunderbird trunk, so it will be great to have server to test and use with :). Thanks
