[Dovecot] Outlook problem when deleting mails
by Ulf Jaenicke-Rößler 20 Oct '10

20 Oct '10

Hi, I'm seeking advice to solve the following "mystery": I set up an IMAP server on Ubuntu 10.04 (dovecot 1.2.9). It appears to work fine apart from one problem. A colleague is running Outlook 2007 on Vista and sometimes (sometimes very often, sometimes only occasionally) when he wants to delete mails, Outlook hangs for some time (he says about 1, 2 or 3 minutes) until it finally puts out a message box: "The server did not respond to this IMAP command before the connection was terminated" I have activated the outlook-idle workaround, but I learned that this doesn't do anything anymore, right? There's no error message in dovecot's logs. Nevertheless, today I found this around the time the error happened: 2010-10-12 17:13:02 imap-login: Info: Login: user=<user>, method=PLAIN, rip=192.168.100.53, lip=192.168.100.20 2010-10-12 17:13:03 imap-login: Info: Login: user=<user>, method=PLAIN, rip=192.168.100.53, lip=192.168.100.20 2010-10-12 17:15:07 IMAP(user): Info: Disconnected in IDLE bytes=272298/631645 2010-10-12 17:15:07 IMAP(user): Info: Disconnected: Logged out bytes=63/539 2010-10-12 17:15:07 IMAP(user): Info: Disconnected: Logged out bytes=462/47082 What exactly does "Disconnected in IDLE" mean? Could the error be related to the same time stamp? (I'm not yet sure, if it always happens this way if the error occurs) I also found "Disconnected in IDLE" for other users at other times, but no one other complained so far. Maybe, that's because most of the other users use Thunderbird ;-) Is this problem known? What could I do? Best regards Ulf

[Dovecot] (Single instance) attachment storage with single-dbox
by Timo Sirainen 19 Oct '10

19 Oct '10

Just a note to myself and whoever else cares, should be added to wiki once it has its own page about this: With single-dbox messages can be copied with hard linking. This means that there can be multiple files that point to the same attachment file. The attachment is now deleted only once the mail file's link count drops to zero, so this works fine.. ..until someone goes and starts manually copying files or maybe restoring from backups or whatever, causing the hard links to be replaced with separate files having link count=1, even when there are other files pointing to the same attachment file. Now deleting this one mail will delete the attachment too early. I can't think of any other reasonable way to handle this though, so unless someon has some great ideas, I think the solution is to simply add enough warnings that message store shouldn't be accessed directly. Maybe add some import/export commands to doveadm which can be used to add a bunch of mails to storage without doing it directly on filesystem.

[Dovecot] gssapi problems (postfix sasl through dovecot, dovecot imap working fine)
by Trever L. Adams 19 Oct '10

19 Oct '10

Thanks to Timo, I have solved all but one of my problems. For back ground, I am using Samba4 as an AD. I have the userdb working from LDAP just fine and kerberos authenetication for dovecot's IMAP server working fine. The problem is using dovecot's SASL with postfix. I also have plain/login working in imap and smtp. Both use pam_krb5 through pam to authenticate clients that don't have kerberos, and for now smtp. When trying to do smtp kerberos, I get the following: postfix/smtpd[6197]: warning: CLIENT_FQDN[CLIENT_IP]: request longer than 2048: AUTH GSSAPI ... dovecot: auth: Debug: client in: AUTH#0111#011GSSAPI#011service=smtp#011nologin#011lip=SERVER_IP#011rip=CLIENT_IP#011secured#011resp=<hidden> dovecot: auth: Debug: gssapi(?,CLIENT_IP): Obtaining credentials for smtp@MAILSERVER_FQDN dovecot: auth: gssapi(?,CLIENT_IP): While processing incoming data: Unspecified GSS failure.

Any help would be greatly appreciated. I have made sure that the file has proper permissions. I have regenerated the smtp cert making suer the password is accurate. I have done everything I know to try. The only thing that I am guess remains is something is broken with Thunderbird's kerberos setup for smtp. Thank you very much, Trever

[Dovecot] Imap Logout format
by Antonio Perez-Aranda 19 Oct '10

19 Oct '10

He all, I'm migrating a big system from Courier to Dovecot and we have a custom analyzer logger system to Courier logs. We have got the very similar specs on IMAP LOGIN log, but I can't get the Logout format. Courier write like that: ... imapd: LOGOUT, user=luism.martinez, ip=[::ffff:127.0.0.1], headers=0, body=0, rcvd=131, sent=632, time=0 ¿Is there any Variables on imap_logout_format to get headers, body and time vars?

Hello Dovecot v2.0.5 zlib_save_level = 6 # 1..9 zlib_save = gz # or bz2 Is there a config option to disable zlib, even if above config are in place? If so please provide an example. If no, would it be possible to add one? Like if zlib_save_level = 0 disable zlib. So one can configure per mailbox compression level via sql database. KuiZ Thanks

Hello, another problem with changed separator (2.0.5-0~auto+23 (b8803a1e2dc2)).

[Dovecot] cmusieve and logging

18 Oct '10

Hello, is there a way to write a logfile during sieve-actions? At least, I have trouble in reading sieve-scripts with tools from kmail ("connection refused) or thunderbird (timed out: server does not answer). There is no problem with the mailbox itself in reading or writing in it. The config for Sieve: dovecot.conf: ## ## LDA specific settings ## protocol lda { # Address to use when sending rejection mails. postmaster_address = christoph@localhost # Hostname to use in various parts of sent mails, eg. in Message-Id. # Default is the system's real hostname. #hostname = # Support for dynamically loadable plugins. mail_plugins is a space separated # list of plugins to load. # Binary to use for sending mails. #sendmail_path = /usr/lib/sendmail # UNIX socket path to master authentication server to find users. #auth_socket_path = /var/run/dovecot/auth-master debug = yes log_path = /var/log/dovecot/dovecot-deliver-errors.log info_log_path = /var/log/dovecot/dovecot-deliver.log # Enabling Sieve plugin for server-side mail filtering mail_plugins = cmusieve } plugin { # Here you can give some extra environment variables to mail processes. # This is mostly meant for passing parameters to plugins. %variable # expansion is done for all values. #sieve = /var/sieve-scripts/%u/sieve sieve=~/.dovecot.sieve # Quota plugin.

[Dovecot] After Upgrade to Dovecot 2.0.5 SSL problems

18 Oct '10

Hi, I've upgraded my Dovecot from 1.2 to 2.0.5. Everything is working fine on my Gentoo, also login with imaps and pop3s. But: I have in my config autocreate folders for new users. After creating a new user (with PostfixAdmin) I see in my logfile with SSL enabled this: imap-login: Warning: SSL alert: where=0x4004, ret=560: fatal unknown CA [127.0.0.1] With SSL-disable, autocreation folders for new users is no problem. I've searched a fiew days for a solution, but I did not find anything. Also dovecot-page what describes running SSL does not help me. Here are the relevant config-sniplets: plugin { autocreate = Trash autocreate2 = Sent autocreate3 = Junk autocreate4 = Drafts autosubscribe = Trash autosubscribe2 = Sent autosubscribe3 = Junk autosubscribe4 = Drafts } service imap-login { inet_listener imap { address = * port = 143 } inet_listener imaps { address = * port = 993 } } ssl = yes ssl = yes ssl_cert =

I'm concerned with the very same question. I currently have 1.2.12 running very well and I see risk in an upgrade to ver 2.x. Unless of course the benefits outweigh the risks. I have been carefully watching the ver 2.x tree rev from week to week and I await the defacto signal from people that it is in fact at least as solid at 1.2.12, that signal being adoption by people in busy mail servers.

There is still a rather large number of Solaris 8 Sparc servers out there running in production and based on the conversations I have had with some sysadmins they will upgrade them when the smoke comes out. That could be another five years. So, before you say "stability has less to do with that" you should see the horrendous work it takes to port an app from the open source world ( usually Linux people with tons of Linux-isms/GCC-isms in it ) over to an old POSIX/XPG4 ( POSIX.1-1990, POSIX.2-1992, POSIX.1b-1993, POSIX.1c-1996 etc ) compliant UNIX.

[Dovecot] Version checks and API/ABI/sonames
by Axel Thimm 18 Oct '10

18 Oct '10

Hi, pigeonhole/sieve check against dovecot's version comparing to what they have been built against. This means that whenever there is a minor version of dovecot released pigeonhole/sieve need to be rebuilt and then redistributed to users even if there is no need for it (I'm thinking of packaged versions of dovecot and dovecot-pigeonhole). Could the checks become ABI-version aware, so that rebuilds and redistribution are kept to a minimum? Maybe Timo is already keeping API/ABI stability between minor updates, so the version checks should be against the first two version components only. Thanks! -- http://thimm.gr/ - http://ATrpms.net/

[Dovecot] Retrieving unread message count
by Brandon Davidson 18 Oct '10

18 Oct '10

Timo, I'm working with a webmail client that periodically polls unread message counts for a list of folders. It currently does this by doing a LIST or LSUB and then iterating across all of the folders, running a SEARCH ALL UNSEEN, and counting the resulting UID list. Eventually I'd like to see it using RFC5819 LIST-EXTENDED, but that requires a fair bit of work. In the mean time I'm trying to speed up the existing iteration. I've got it working using 'STATUS "mailbox" (UNSEEN)', but the language in RFC3501 suggest that this may be slow. There is a counterproposal to use RFC4731 ESEARCH and do 'SELECT "MAILBOX"'; 'SEARCH RETURN (COUNT) UNSEEN'. >From an IMAP server perspective, which do you anticipate would be faster? >From a client perspective it seems like STATUS would be better since it involves less round-trips to the server and less output parsing, but given the warnings in the RFCs there is concern that it is in fact be more expensive. -Brad

Huh? What are you talking about? If dovecot has tcpwrapper support and is compiled -DTCPWRAP then it can run as a standalone daemon and will consult the hosts.allow/deny files, no need for inetd of any type. man 3 hosts_access man 5 hosts_access for details on tuning. Tcpwrapper tuning is far more powerful than people realise.

[Dovecot] strange behavior with virtual accounts and imap
by vladi 18 Oct '10

18 Oct '10

hi, I've recently setup new mailserver with dovecot and postfix. They use mysql and virtual accounts. All works perfectly except.. There is one group account named info, all the mail is forwarded to every other account. Users download their mail via Outlook (2003, 2007) with imap. If someone downloads email send to info and delete it after that. Outlook stoke the message and doesn't delete it immediately, thats normal. But if later someone else downloads his mail and it have received the same letter to info. The message appear as if it's already deleted by that user. But is supposed to be unreaded. I cant find any info why is this happening. Please help

The quota is working, gets updated but I had to configure really loose file permission to make it work: dovecot.conf: dict { quota = pgsql:/etc/dovecot/dovecot_dict-sql.conf } service dict { unix_listener dict { mode = 0660 group = vmail # sidenote: I noticed that writing the number equivalent # of 'vmail' here does not work. Why? } } # ~ls -la /etc/dovecot/dovecot_dict-sql.conf -rw-r----- root vmail dovecot_dict-sql.conf # ~ls -la /var/dovecot/dict srw-rw---- root vmail /var/dovecot/dict= Every virtual user lookup returns a 'gid' field, and it is always 'vmail' (actually it is the number equivalent of 'vmail'). Despite that the imap process should run as the 'uid' and 'gid' values returned from the userdb, it can not read the dict config file: dovecot.log: dict: Error: Can't open configuration file /etc/dovecot/dovecot_dict-sql.conf: Permission denied dict: Error: Failed to initialize dictionary 'quota' lda(<username>): Error: read(/var/dovecot//dict) failed: Remote disconnected Now I must set o+r to the config file, which I really don't want to, given that it contains the db username and password. Strange thing is that the group r/w permission is enough for the dict= socket, and it doesn't need world-wide permissions at all.

[Dovecot] kmail-error: can't upload folder (imap-account on dovecot-server)
by cool.chris65＠web.de 17 Oct '10

17 Oct '10

Hello, I've some trouble with my kmail (Version 1.13.5 / KDE 4.5.1, Kubuntu 10.04 and a dovecot-imap-server on debian etch (dovecot 1.0.rc15-2etch5). Everytime I try to create a folder under my imap-inbox, I get an error like "can't upload folder...", but after this message I can see a new folder under my inbox-folder, but I can't use it ... With a thundermail-client I can create a subfolder without any erro and I can use it r (but only first level). My conf: # /etc/dovecot/dovecot.conf log_path: /var/log/dovecot/dovecot.log info_log_path: /var/log/dovecot/dovecot.log disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login login_greeting: Herzlich Willkommen, %u. mail_location: mbox:~/mail imap_client_workarounds: outlook-idle tb-extra-mailbox-sep auth default: passdb: driver: passwd-file args: /etc/passwd.dovecot userdb: driver: passwd The reason for using debian etch and dovecot 1.0 is the hardware: it's running on a Fritzbox-Router, and there is actual a littlebit trouble with lenny (often crashing, reboots of the whole box etc.) I hope, someone can help me ...

[Dovecot] Quota, Postgres + Postfixadmin
by Roman 17 Oct '10

17 Oct '10

Hi everybody, i am currently testing dovecot-1.2.9 together with postfix, postgres and postfixadmin. After setting up the basics, i wanted to get the quotas working... So i edited the dovecot.conf: mail_plugins = quota imap_quota mail_plugins = sieve quota quotadict = pgsql:/etc/dovecot/dovecot-dict-quota.conf quota = dict:user::proxy::quotadict and dovecot-dict-quota.conf: connect = host=localhost dbname=postfix user=yyy password=xxx map { pattern = priv/quota/storage table = quota2 username_field = username value_field = bytes } map { pattern = priv/quota/messages table = quota2 username_field = username value_field = messages } After moving some mail on and off the account and finally cleaning out any mail (verified via console) quota2 looks like this: username bytes messages test(a)testdomain.de -1009339 -1 So it seems to me its calculating sth. wrong? Or am i doing sth. wrong? greetings, Roman -- printk(KERN_ERR "happy meal: Transceiver and a coke please."); linux-2.6.6/drivers/net/sunhme.c

[Dovecot] Convert plugin
by Egbert Jan van den Bussche 15 Oct '10

15 Oct '10

Hi, I'm trying to get old mail from /var/mail/<user>, where <user> is the (sometimes) huge mailfile, not a directory, converted to the maildir INBOX in ~/Maildir. Users have no ~/mail directory; they were supposed to use pop3 only. I'm trying the example from the wiki: plugin { convert_mail = mbox:~/mail:INBOX=/var/mail/%n } but have still not succeded. I tried /var/mail/<user> where <user> is a file and /var/mail/<user>/<user> where user is first a diredtory en the second <user> a file. I also used the filename 'inbox', since the logging suggested that to me. Other logging seems to indicate that the right maildir++ info is composed. I'm in vor any advise!

[Dovecot] Weird glitches with public folders - Dovecot not using per-user INDEX?
by Kádár Tamás (KTamas) 15 Oct '10

15 Oct '10

Hi I have this public folder: namespace { location = maildir:/home/_shared/projects:INDEX=~/Maildir/_shared prefix = shared. separator = . subscriptions = no type = public } Access is controlled by ACLs, everyone who has access is 'lrwstipek' except for some people who also have 'xa' privileges. As you can see it is set to put its index to the user's Maildir so they can have per-user \Seen flags. And that is the case -- most of the time anyway. But for some folders, and I can't figure out why those, they just don't work: if someone sets a message read it immediately becomes read for everyone else, too, and vice versa if someone marks a message unread, it becomes unread everywhere. Further investigation shows that in these problematic folders, indeed all users directly manipulate the flag of the email (i.e. X marks email Z read, ",S" appears immediatelly in the filename). Anyone knows what I'm doing wrong? I can't seem to find anything different with these problematic folders, ACLs look right etc. Thanks in advance, Tamas

[Dovecot] Custom Flags
by qmail＠top-consulting.net 15 Oct '10

15 Oct '10

I have modified my delivery agent to deposit files in my Maildir already containing custom flags. For example, x is appended for files that are sent from local users, y is for e-mails from Contacts and z is for e-mails from Whitelisted sources. A file will thus be delivered in the Maildir and be called something like: filename:2,yz Also in the Maildir I created a file called dovecot-keywords and have added these 3 flags in there as so: #cat dovecot-keywords 23 Local 24 InContacts 25 Whitelisted I went ahead and erased all the dovecot-uid* dovecot.index* files but Dovecot won't recognize the flags - furthermore, it labels z as 'unknown-25'! - for both old messages or new messages. Here is a bit of IMAP conversation: a02 select inbox * FLAGS (\Answered \Flagged \Deleted \Seen \Draft unknown-25 Whitelisted ) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft unknown-25 Whitelisted \*)] Flags permitted. a03 SEARCH KEYWORD Whitelisted * SEARCH * FLAGS (\Answered \Flagged \Deleted \Seen \Draft unknown-25 Whitelisted Whitelisted) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft unknown-25 Whitelisted Whitelisted \*)] Flags permitted. a03 OK Search completed (0.004 secs). a04 SEARCH KEYWORD unknown-25 * SEARCH a04 OK Search completed (0.004 secs). I know for sure there are files with the z letter in their name in the Inbox. What is going wrong ?

[Dovecot] Limit access to dovecot by domains?
by Jobst Schmalenbach 15 Oct '10

15 Oct '10

Hi. Is there any way to limit access to dovecot by domains. I only need to give access to a well known set of domains, all from Australia and all networks are known and used either from people at home or mobile access (phones, laptops etc). iptables is not possible as e.g. OPTUS does not give away all of the networks mobile phones are connected to. I know some, but not all. It would be much nicer and easier to allow optusnet.com.au bigpond.com.au tpg.com.au and I have given 100% of our users access. I know there is an extra field called "allow_nets", I tried this and failed. I did a search and found that this only works with SQL? Maybe I could include a script that would check the reverse DNS record of a connected IP and then I could filter?????

The problem is when doing doveadm stuff. I do not know ldap (learning as I go). I need to set the uid/guid to vmail (500 in this case if vmail can't be used). Any help would be greatly appreciated. I do not have sfu or rfc2xxx enabled as this requires changing things with Samba 4 that I would rather avoid at the moment.

[Dovecot] Master user sees empty folder list
by interfaSys sàrl 15 Oct '10

15 Oct '10

Hello, I'm having a "path" problem with master users. When logged on as a master user, I can't see the user's folders. I'm trying to use system users as master users, so I'm using something like this: # Master password auth_master_user_separator = * passdb { driver = passwd master = yes pass = yes } # System users passdb { driver = passwd } # Virtualusers users passdb { driver = passwd-file args = username_format=%n /etc/virtual/%d/passwd } mail_location = mdbox:~/mdbox System and virtual users see their folders fine, including the shared namespaces, but as a master user, I see an empty mailbox. I've turned on debugging and watched things like root= and fs= and they're normal. Permissions should be OK since the system user has the same uid:gid as the virtual user. What could it be? Cheers, Olivier

[Dovecot] "doveadm mailbox create" oddities
by Andre 15 Oct '10

15 Oct '10

Hi to all! I’m trying to understand the usage of "doveadm mailbox create”. If I do, as root: # doveadm mailbox create -u __public__ sys/test doveadm(__public__): Error: Can't create mailbox sys/test: Permission denied but if I do: # doveadm mailbox create -u __public__ test every thing is OK. “sys" is a shared maildir folder, that is visible in the client as "#Public/sys”. __public__ is the user that owns Public folders, here is the complete details: userdb: __public__ uid : 10002 gid : 8 home : /var/mail/domainname/__public__ mail : maildir:~/maildir:INBOX=~/maildir/INBOX:LAYOUT=fs:INDEX=~/indexes/ Do I have to add root with proper permissions to ACL? TIA Andre

[Dovecot] Dovecot chgrp actions on new files/folders
by David Ford 14 Oct '10

14 Oct '10

Timo, I did further study of the user/group permissions. Applying the below patch will make no difference to virtually everyone out there. Those that have default uid/gid ownership won't see any change as the gid already matches so the fchown() action won't be attempted. Those that have sgid will still see the normal expected fchown() enforced by the kernel which becomes a duplicated action by dovecot. In the last case, those with an unknown 3rd party gid were used to seeing fchown() failures and those will now go away. It is only this third group that will see anything change as all other cases are already handled. Anyone who wishes to create new files with another group ID should make their directories sgid or stgid as per normal filesystem ACL semantics. The original net effect of this only turns on an fchown() that will fail and emit numerous error messages. This patch fixes that. Technically the fchown is unneccessary extra code already since any directory that is sgid or stgid will have ownership enforced by the kernel already. I simply made it #if 0 below, the correct patch would be to delete the extraneous block. --- src/lib-storage/mailbox-list.c.orig 2010-09-14 11:03:18.000000000 -0400 +++ src/lib-storage/mailbox-list.c 2010-10-08 13:02:54.000000000 -0400 @@ -450,7 +450,7 @@ } if (S_ISDIR(st.st_mode) && (st.st_mode & S_ISGID) != 0) { - /* directory's GID is used automatically for new + /* directory is sgid, so GID is used automatically for new files */ *gid_r = (gid_t)-1; } else if ((st.st_mode & 0070) >> 3 == (st.st_mode & 0007)) { @@ -460,9 +460,13 @@ } else if (getegid() == st.st_gid) { /* using our own gid, no need to change it */ *gid_r = (gid_t)-1; - } else { + } +#if 0 +#warning this code makes dovecot attempt to chgrp files to wrong ownership + else { *gid_r = st.st_gid; } +#endif } if (name == NULL) {

[Dovecot] lazy_expunge and moving messages
by Lutz Preßler 14 Oct '10

14 Oct '10

Hello, testing the lazy_expunge plugin (with 2.0.5), I realized the following effect, which users may not expect/understand: As moving messages from one folder to another has to be done by clients with the IMAP command sequence COPY STORE EXPUNGE, every moved message is also put into the "shadow folder" of the source folder. Maybe it's possible to extend the plugin to optionally hook into the COPY operation, remember it somewhere with the message (simply as special/ configurable IMAP flag?), and then really expunge messages with this flag set. What do you think? I haven't looked into the plugin interface yet. Of course, if a user manually copies a message and deletes the source message later (maybe having the copy deleted inbetween...), the consequence may not be expected either...

[Dovecot] limits to serve sure a number of users
by Schmidt 14 Oct '10

14 Oct '10

Hi, lets say dovcot should serve 1000 user (only imaps) without rejecting a users connection because of to short resources. With version 1.x I had to increase login_max_processes_count = ... With 2.x I'm not sure which parameters I have to set. So Thunderbird 3.x has a default value of 5 connections to cache. "dovadm who" shows quite often 5 connections: userx 5 imap (11154 11152 11158 11156 11150) ... So dovecot has to be configured for 5000 connections/imap-login's? Within 10-master.conf these defaults are shown #default_process_limit = 100 #default_client_limit = 1000 Is it right process_limit is not generally a problem because oldest imap-login process(?) will be closed? (With this expected number of users this value should be increased too.) But what about client_limit? Does it has to be increased to 5000? (There have been some hints by Timo concerning "doveconf -a service" to see how limits will be used for different services.) Any advices? thanks -- Mit freundlichen Gruessen --- Burckhard Schmidt

[Dovecot] userdb syntax
by suzuki 14 Oct '10

14 Oct '10

Hello, I have a question about userdb lookup when using expire-tool. Dovecot version 1.2.15 In dovecot.conf, mail_location = maildir:/var/mail/%u:INDEX=/var/indexes/%u I run dovecot expire-tool, target user's directory becomes executing user's one. According to wiki, userdb setting overrides mail_location. userdb passwd { mail=maildir:/var/mail/%u:INDEX=/var/indexes/%u } With this setting, it seems working. But, there are no examples with ":INDEX=.." setting. Is this syntax right? Regards

[Dovecot] Problem with dovecot-acl was not solved
by dss 14 Oct '10

14 Oct '10

Problems with acl in dovecot-1.2.15 was not solved! See my configs below. And I see the new bug - still something wrong with configs: cat dovecot-acl: user=t1 lrwsti #user=oper-olegs lrwsti #user=oper-antona lrwsti user=operdss lr #user=operdss lrwsti User t1 can't create subfolers in inbox. He can only create subfolders in the first levels: Inbox test3 test4 Outbox Sent Trash Test1 - test folder created by t1 user Folders test3 and test4 can't be deleted by t1 - why? Owner of the test3 and test4 - annother user, but but with group rights everething is fine. User operdss also can create folders in the same level with such permissions.

Some of our users need to use the same Mailbox with all folders: Inbox (with subfolders), Outbox, Send and Deleted, (some users need in full righs, some - readonly) so I choosed Symlinking mailboxes and tried to use dovecot-acl file. cat dovecot-acl: user=t1 lrwsti user=operolegs lrwsti user=operantona lrwsti user=operdss lr User operdss have lrwsti rights in this shared mailbox unstead of lr! But if I comment out other users in the dovecot-acl: #user=t1 lrwsti #user=operolegs lrwsti #user=operantona lrwsti user=operdss lr User operdss have lr rights. Whats wrong? It seems, that dovecot-acl is working only for one user and for one line in config. How can I fix it? === Here is my configs. imap:/usr/local/dovecot# /usr/local/dovecot/sbin/dovecot -n # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.26-2-686 i686 Debian 5.0.6 log_path: /var/log/dovecot.log log_timestamp: %Y-%m-%d %H:%M:%S disable_plaintext_auth: no login_dir: /usr/local/dovecot-1.2.15/var/run/dovecot/login login_executable: /usr/local/dovecot-1.2.15/libexec/dovecot/imap-login mail_privileged_group: mail mail_plugins: acl imap_acl auth default: debug: yes passdb: driver: pam userdb: driver: passwd ---- imap:~# ls -l /home/t1/Maildir lrwxrwxrwx 1 root root 21 2010-09-22 16:03 /home/t1/Maildir -> /var/mail/720/Maildir imap:~# ls -l /home/operolegs/Maildir lrwxrwxrwx 1 root root 21 2010-09-23 16:00 /home/operolegs/Maildir -> /var/mail/720/Maildir imap:~# ls -l /home/operantona/Maildir lrwxrwxrwx 1 root root 21 2010-09-23 16:00 /home/operantona/Maildir -> /var/mail/720/Maildir imap:~# ls -l /home/operdss/Maildir lrwxrwxrwx 1 root root 16 2010-09-28 16:32 /home/operdss/Maildir -> /home/t1/Maildir --- imap:/home/t1/Maildir# ls -l total 112 drwxrws--- 2 t1 mshare 4096 2010-09-27 10:46 cur -rw-rw---- 1 t1 mshare 99 2010-09-29 15:56 dovecot-acl -rw-rw---- 1 operdss mshare 312 2010-09-29 16:43 dovecot-acl-list -rw-rw---- 1 operolegs mshare 1144 2010-09-24 12:16 dovecot.index -rw-rw---- 1 t1 mshare 41984 2010-09-28 16:39 dovecot.index.cache -rw-rw---- 1 t1 mshare 25068 2010-09-28 16:38 dovecot.index.log -rw-rw---- 1 operantona mshare 17 2010-09-23 16:41 dovecot-keywords -rw-rw---- 1 operantona mshare 1941 2010-09-27 10:46 dovecot-uidlist -rw-rw---- 1 t1 mshare 8 2010-09-29 16:43 dovecot-uidvalidity -rw-rw---- 1 t1 mshare 0 2010-09-22 10:54 dovecot-uidvalidity.4c99a82f drwxrws--- 2 t1 mshare 4096 2010-09-27 10:46 new -rw-rw---- 1 operdss mshare 327 2010-09-29 16:43 subscriptions drwxrws--- 2 t1 mshare 4096 2010-09-27 10:46 tmp ----- dovecot packages - dovecot-1.2.15 --- Linux: Debian Lenny up2date
