[Dovecot] Differences between IPv4 and IPv6 authentication
by Tony Meyer 02 Nov '10

02 Nov '10

Hi, I have Dovecot listening on both IPv4 and IPv6, and can connect on both interfaces, but cannot authenticate over IPv6, using exactly the same credentials as IPv4. I assumed that the same authentication mechanisms would be used, regardless of the protocol being used - are there differences somewhere? For example: ~$ telnet server1.teststable.simplyspamfree.com 143 Trying 2a01:4f8:100:12c1:bc:28:b2:34... Connected to server1.teststable.simplyspamfree.com.

[Dovecot] fts_solr on debian lenny dovecot 1.2.15
by a＠test123.ru 02 Nov '10

02 Nov '10

Hello, I cannot run FTS SOLR engine. OS is debian lenny. I re-compiled debian package (from backports) with --with-solr option. Dovecot loads fts_solr plugin. I know that it loads plugin because if I remove lib21_fts_solr_plugin.so, dovecot does not start. But it does not attempt to communicate with SOLR. Simple check: stop solr tomcat, and open 8080 port in netcat: $nc -l -p 8080 dovecot never tries to connect to 8080 when I search message by IMAP. I removed indexes, it did not help.

[Dovecot] Problem with excel and word attachements ?
by Frank Bonnet 02 Nov '10

02 Nov '10

Hello We are in (random) troubles with some emails that contains word and excel attachements ( others attachements are OK ) I don't really think Dovecot is implied in this trouble but I want to be sure ... The problem is users cannot open attachements from their clients ( thunderbird 3.1 ) it stays in "download" mode until timeout. Maybe there is a Dovecot's workaround to solve that boring problem ? Thank you

[Dovecot] Linux Bootup: Dovecot Failure
by Christopher Metter 01 Nov '10

01 Nov '10

Hi there! Im using a dovecot system in combination with postfix(with dovecot lda) and ldap. Till today it ran well, but before switching to live, i did some system updates and at the reboot following message occured: Starting IMAP/POP3 mail server: dovecoUnexpected first line <localhost: timed out, nothing received> (First it says: "Starting IMAP/POP3 mail server: dovecot ", but then something fails and overrides the "t" of dovecot with "Unexpected.... ") I don't know when this error occured first, but it only goes away if i delete dovecot from autostart at bootup (by renaming dovecot-file in /etc/rc2.d/ ) No error shown in /var/log/mail.* or syslog Apart from showing this message, system is running perfectly. Users can login, receive their mail and produce new mail-traffic with postfix ;) ATM i really dont know what to do, im near switching to live status of this system and that message is annoying me. Didnt find any information on the net. Hope someone on this list can give an helpful advice Dovecot version: 1.2.15 Greetings from Germany, Christopher Metter dovecot -n: http://nopaste.info/0447cd09ba.html Boot log: http://nopaste.info/index.html

[Dovecot] Mailing lists in Dovecot?
by Peter Reinhold 01 Nov '10

01 Nov '10

Hi all, I was wondering if anyone could recommend a simple mailing list manager that plays well with a Postfix/Dovecot setup, with virtual domains? It really just has to be very simple, basically, an alias would work, if I could rewrite the sender address/name, and I don't really need the possibility for users to subscribe via e-mail based commands. I've looked at the XEXEC plugin as a possible method of doing this, via some Perl perhaps, anyone has any experience using this they would like to share? Mvh, Peter Reinhold / peter(a)reinhold.dk

[Dovecot] auth child abort - "Requested NTLM scheme, but we have only SSHA256"
by LEVAI Daniel 01 Nov '10

01 Nov '10

Hi! I noticed these messages in my logs. It seems that the user checked the "encrypted password" in her outlook or something, and wants NTLM auth. I'm storing all the passwords as SSHA256, and when the user tries to auth, this happens: => dovecot.info auth: Info: password(<username>,<user_ip>): Requested NTLM scheme, but we have only SSHA256 auth: Debug: sql(<username>,<user_ip>): query: SELECT username AS user, password, home AS userdb_home, uid AS userdb_uid, gid AS userdb_gid, userdb_import AS userdb_userdb_import FROM userdb WHERE auth_username = '<username>' AND login = 'enabled' => dovecot.log auth: Error: sql(<username>,<user_ip>): Multiple password values not supported auth: Panic: file passdb-sql.c: line 113 (sql_query_callback): assertion failed: (password == NULL || scheme != NULL) master: Error: service(auth): child 10679 killed with signal 6 (core not dumped - set service auth { drop_priv_before_exec=yes }) Is this an error condition if I store the password in a different scheme than what user is requesting?

[Dovecot] Testing pop3/imap4 and mdbox corrupted indexes?
by Odhiambo Washington 01 Nov '10

01 Nov '10

I have two questions: 1. What method/tool (other than a MuA) can I use to test my Dovecot setup from Windows CLI when ssl is enabled? I have tried connecting to to the pop3/imap4 services from a Windows PC but here is what I get: [pop3] +OK Dovecot-2.0-sis ready. user wash(a)domain.co.ke -ERR Plaintext authentication disallowed on non-secure (SSL/TLS) connections. [imap4] OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE STARTTLS LOGINDISABLED AUTH=DIGEST-MD5] Dovecot-2.0-sis ready. login wash(a)domain.co.ke S3ecreat BAD [ALERT] Plaintext authentication not allowed without SSL/TLS, but your client did it anyway.

[Dovecot] [OT] dovecot appliance
by Johan Hendriks 29 Oct '10

29 Oct '10

Hello all. I am reading the mailinglist for a long time now, and there was a thread i believe called webgui or something. In this thread there was a company i believe german, that was working on a dovecot appliance with a web based gui to administrate a dovecot mail server. The problem is i did not save the URL of that company. Does anyone know which company make the appliance. Or does anyone knows a good webbased tool for dovecot. The reason is that in a windows environment, with only a few FreeBSD machine's , my collega's get frustrated if they can not use a mouse. They even want a mouse on there smartphone's :D I am doing the administration of the mail server, but when i am not there, it would be nice if they can do things them selves. thanks for your time. regards, Johan Hendriks

[Dovecot] Upgrading from 1.2.8 to 2.0.6: INBOX not selectable in Thubderbird (greyed and italic)
by Michele Bergonzoni 29 Oct '10

29 Oct '10

I recently upgraded from 1.2.8 to 2.0.6, I am using Maildir, and Thunderbird is showing the INBOX grayed out and in italics, and does not show new messages in it (it shows messages previously downloaded). This occurs when Thunderbird is restarted (if I upgrade dovecot, TB keeps working fine until I shut it down, and at next startup it greys out the inbox). All the subfolders of INBOX work fine. Accessing with horde+imp webmail works fine. I'm using TB 3.1.6 After some traffic capturing, The first difference I see in the IMAP exchange is the answer to 6 list "" "INBOX" Which for 1.2.8 is: LIST (\HasChildren) "." "INBOX" and for 2.0.6 is: LIST (\Noselect \HasChildren) "." "INBOX" Of course for the same user and same maildir. I enabled tb-extra-mailbox-sep in 2.0, but it doesn't appear to differ (I don't really think it should). Any help will be very much appreciated. My 1.2.8 config for the namespaces is: namespace private { prefix = INBOX. inbox = yes location = maildir:~/Maildir } namespace public { prefix = shared. location = maildir:/usr/local/shared list = yes subscriptions = no } And the config for 2.0.6 is the same with new syntax: namespace { type = private prefix = INBOX. inbox = yes location = maildir:~/Maildir } namespace { type = public prefix = shared. location = maildir:/usr/local/shared list = yes subscriptions = no } Regards, Michele Bergonzoni

[Dovecot] Can you POP a specific folder in Dovecot?
by Peter Reinhold 29 Oct '10

29 Oct '10

Hi all, I am in the middle of migrating from an old, Windows based mailserver, and have run into a small challenge I hope someone here can help me with. In my old setup, a user could have folders on the server, and by using his login with the mailbox appended, could pop a given folder specifically. For instance, logging in with user(a)example.com would pop INBOX, and logging in with user-folder(a)example.com would pop just that specific folder. Is it possible to do something like this in Dovecot, or is the only possible way of popping folders by using the virtual plugin?

[Dovecot] Released Pigeonhole v0.2.1 for Dovecot v2.0.4
by Stephan Bosch 29 Oct '10

29 Oct '10

Hello Dovecot users, There haven't been that many Pigeonhole developments lately, not even really significant bugs were reported. That is why this release is pretty small in terms of changes. However, one issue got some attention: the fact that not recompiling Pigeonhole for Dovecot v2.0.3 would result in rather interesting message delivery. Normally, Dovecot would complain about a version mismatch, but unfortunately Pigeonhole's Sieve plugin didn't record the Dovecot version it was compiled with. Starting with this release, such problems should not occur again. Changelog v0.2.1: + Incorporated distinction between original and final envelope recipient in Sieve interpreter, as recently introduced in Dovecot. + Regex extension: added support for regex keys composed from variables. - LDA Sieve plugin: added _version symbol to enable Dovecot's plugin version check. Without this check, people can forget to recompile the plugin, which can lead to unexpected effects. - LDA Sieve plugin: turned debug message about an unconfigured home directory into a proper error and added script path information. - Fixed unnecessary reporting of dummy extensions in ManageSieve SIEVE capability; the comparator-i;octet and comparator-i;ascii-numeric 'extensions' were reported explicitly. The release is available as follows: http://www.rename-it.nl/dovecot/2.0/dovecot-2.0-pigeonhole-0.2.1.tar.gz http://www.rename-it.nl/dovecot/2.0/dovecot-2.0-pigeonhole-0.2.1.tar.gz.sig Refer to http://pigeonhole.dovecot.org and the Dovecot v2.0 wiki for more information. Have fun testing this new release and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

[Dovecot] problem with virtual plugin/index files?
by Lutz Preßler 29 Oct '10

29 Oct '10

Hello, with latest 2.0.6 (601065674f74), the following virtual mailbox is not behaving correctly. I'm quite sure that the problem has not existed in some earlier 2.0.x (maybe only INBOX as mailbox then though): ~user/Maildir/virtual/.week/dovecot-virtual contains INBOX INBOX.* -INBOX.Trash inthread refs younger 604800 This works as expected for the first time. But later on, also older messages/ threads are included until I delete the virtual/.week/dovecot.index*.

Just made the leap from 1.2 to 2.0.6 - and several maddening config typos I think I have a working system again! Getting closer to converting from maildir to mdbox, but first... Trying to use dsync gives me: dsync(root): Fatal: Mail locations must use the same virtual mailbox hierarchy separator (specify separator for the default namespace) Ok - I 've never configured namespaces before...time to learn. So my first attempt - is the following config the same as having no explicit namespace declaration?: # My Default Namespace namespace { type = private separator = '.' prefix =. location = /var/mail/%d/%n/Maildir inbox = yes hidden = no list = yes subscriptions = yes } -- Daniel

[Dovecot] Problem with quota and mdbox and quota warning
by Patrick Westenberg 28 Oct '10

28 Oct '10

Hi again, I just recognized that my dovecot forgets the quota for a mailbox. This is what the maildirsize looks like: 1 read mail present, 1 new/unread mail 2097152S 0 0 909936 1 and later, with 2 read mails: 2097152S 0 0 There are no errors logged. Moreover, my quota warning script doesn´t work because dovecot doesn´t recognize my specified folder. I specified /usr/local/etc/dovecot/quota-warning.sh but the log shows that dovecot looks somewhere else: Error: quota: connect(/usr/local/var/run/dovecot/quota-warning) failed: Permission denied # 2.0.1: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 2.6.26-2-amd64 x86_64 Debian 5.0.5 disable_plaintext_auth = no mail_gid = vmail mail_location = mdbox:~/mdbox mail_plugins = quota mail_uid = vmail managesieve_notify_capability = mailto managesieve_sieve_capability = comparator-i;octet comparator-i;ascii-casemap fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date namespace { inbox = yes location = prefix = INBOX. separator = . type = private } passdb { args = /usr/local/etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { quota = maildir:User quota quota_rule2 = INBOX.Trash:storage=+50M quota_warning = storage=90%% quota-warning 90 %u quota_warning2 = storage=75%% quota-warning 75 %u sieve = ~/.dovecot.sieve sieve_global_path = /usr/local/etc/dovecot/sieve/default.sieve } protocols = lmtp imap sieve service auth { unix_listener /var/spool/postfix/private/auth { mode = 0666 } } service imap-login { service_count = 1 } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0660 user = postfix } } service managesieve-login { inet_listener sieve { port = 4190 } inet_listener sieve_deprecated { port = 2000 } service_count = 1 } service quota-warning { executable = script /usr/local/etc/dovecot/quota-warning.sh user = vmail } ssl = no userdb { args = /usr/local/etc/dovecot/dovecot-sql.conf.ext driver = sql } protocol lmtp { mail_plugins = $mail_plugins sieve } protocol lda { mail_plugins = $mail_plugins sieve } protocol imap { mail_plugins = $mail_plugins imap_quota }

[Dovecot] Can quota_rule be inherited by child mailboxes?

28 Oct '10

Is there a way to make quota_rule apply to subfolders? I've got some symlinked mailboxes which I want to exclude from quotas. This would work, but is verbose: quota_rule6 = USERS.aaa:ignore quota_rule7 = USERS.bbb:ignore ... quota_rule9999 = USERS.zzz:ignore But simply writing this: quota_rule7 = USERS:ignore doesn't apply to USERS.xxx and so on. The wiki says '*' isn't supported as a wildcard and frankly I'm struggling with the source code!

[Dovecot] Per User Quotas with LDAP on Dovecot 1.x
by Camron W. Fox 28 Oct '10

28 Oct '10

Alle, We're running Dovecot V1.0.7 on RHEL5.5, using maildir. We would like to user per user quotas with an OpenLDAP (V2.3.43) backend. We have setup a default quota in /etc/dovecot.conf: quota = maildir:storage=10240:ignore=Trash And have the following userdb configs in /etc/doveconf.conf: userdb ldap { args = /etc/dovecot-ldap.conf } and the following user_attrs defined in /etc/dovecot-ldap.conf user_attrs = uidNumber=uid,gidNumber=gid,mailQuotaSize=quota=maildir:ignore=Trash:storage,mail_plugins The user's quota setting is: dn: uid=loadtest,ou=people,dc=subaru,dc=nao,dc=ac,dc=jp mailQuotaSize: 1024000 Dovecot-imap appear to recognize the quota from ldap, as the Thunderbird quota plugin reads the correct info from LDAP if the mailQuotaSize entry exists, and the default storage=10240 from doveconf.conf if there is no LDAP attr. However, deliver bounces the mails with a quota exceeded message: deliver(loadtest): Sep 28 10:46:23 Info: msgid=<20100928204620.B83876402EA(a)loa.subaru.nao.ac.jp> : save failed to INBOX: Quota exceeded deliver(loadtest): Sep 28 10:46:23 Info: msgid=<20100928204620.B83876402EA(a)loa.subaru.nao.ac.jp> : Rejected: Quota exceeded Are we misunderstanding the way quotas are supposed to work in 1.x, or are we just missing something, period?

[Dovecot] imap can't reconnect to auth-master after setuid
by Mike Abbott 27 Oct '10

27 Oct '10

With service imap { client_limit = 5, service_count = 0 }, when the auth process crashes the existing imap processes cannot reconnect to the auth-master socket because they have long ago dropped root privileges. Is the right solution to this: (1) change the perms on the auth-master socket so processes running as vmail:vmail can connect to it, or (2) change the code so that multi-client imap processes stop accepting new clients when they notice an auth bounce? If (1), the wiki should be updated to mention this. Thanks.

[Dovecot] auth crash in 2.0.3

[Dovecot] Smart boxes
by Marcelo Salhab Brogliato 27 Oct '10

27 Oct '10

Hi, I'm using dovecot as IMAP server. I access my mails trough Mail (Mac client), iPhone and webmail. In Mail I use a smartbox that shows all my unread messages, no matter where it is. I really want this feature at my iPhone, so I'm thinking about developing a plugin that will create the smart unread box and follow these rules: - Every new mail arrived, it will create a hard link to directory .smart.unread (in case of Maildir); - Every mark as unread, it will create a hard link; - Every mark as read, it will remove the hard link; - Every mail delete, it will remove all files with same inode. This way, a smartbox with all unread messages will be available into webmail, iPhone and every IMAP client. What do you think about it? Is there a simple way? If it is a cool feature, I'll develop it and post the plugin here. Regards, Marcelo

[Dovecot] Dovecot's maildir format / is rm safe
by ian＠comtek.co.uk 26 Oct '10

26 Oct '10

Is it considered 'safe' to delete directly from a dovecot Maildir? I mean things of the form: rm Maildir/cur/1288062016.M581217P9422.alpha,S=1873,W=1900:2,S The wiki tells me 'If you wish to modify them in any way, create a new message instead and expunge the old one. ' but it doesn't mention deleted files. Specifically I'm wondering what happens with: dovecot.index dovecot.index.cache dovecot.index.log dovecot-uidlist Since (http://wiki.dovecot.org/IndexFiles) tells me these files index each message is there a chance of Dovecot breaking badly if it can't find them? Is it intelligent enough to automatically update the above files when it finds a missing message file? Would simply deleting the 4 files be appropriate? I have users with 4 gig mailboxes so I really wouldn't want to be deleting those files in a script every night if its a long winded process to regenerate them. Thanks in advance for any help, Ian

[Dovecot] post-login scripting using PHP
by Maciej Uhlig 26 Oct '10

26 Oct '10

I'd like to write post-login script using PHP. I noticed every shell post-login script ends with: exec "$@", which effectively executes dovecot's script-login. However, while I try to do the same (?) in PHP: $prog = $argv[1]; exec ("$prog"); it doesn't work. The client timeouts, dovecot (2.0.6) says "Disconnected for inactivity". May be I don't clearly see the way post-login scripting should work. Any hint to make it done? Regards, MU

[Dovecot] Exchange-replacement with SOGo
by Timo Sirainen 26 Oct '10

26 Oct '10

I thought some people here would be interested: Recently SOGo added support for OpenChange, which means Outlook can natively access it via MAPI the same way as Exchange. Everything is open source, and the great thing about SOGo is that it uses existing IMAP server for mails rather than reimplementing yet another one itself. They seem to prefer Cyrus, but apparently Dovecot should work too. For non-mail (calendar, etc) it uses SQL, but I heard it's not too difficult to replace that either if someone would prefer some NoSQL database or something. http://www.sogo.nu/ http://www.openchange.org/

[Dovecot] doveadm-expunge not expunging when ran from cron
by LEVAI Daniel 26 Oct '10

26 Oct '10

Hi! I noticed that this command ... : for USERNAME in ${USERS};do /usr/local/bin/doveadm -Dv expunge -u "${USERNAME}" mailbox sa.* SAVEDBEFORE 1d done ... does not expunge mails if ran from crontab. It shows in the Debug output what would have been done, but it doesn't really expunge those mails. This command runs daily, and every day the list of expunged mails (in the Debug output) just grows and grows, and the sa.* directories stay the same (except the new mails of course). However, if I run it from a terminal it really expunges the mails. Example output: doveadm(root): Debug: Loading modules from directory: /usr/local/lib/dovecot doveadm(root): Debug: Module loaded: /usr/local/lib/dovecot/lib10_quota_plugin.so doveadm(root): Debug: Loading modules from directory: /usr/local/lib/dovecot/doveadm doveadm(root): Debug: Skipping module doveadm_expire_plugin, because dlopen() failed: Cannot load specified object (this is usually intentional, so just ignore this message) doveadm(root): Debug: Module loaded: /usr/local/lib/dovecot/doveadm/lib10_doveadm_quota_plugin.so doveadm("${USERNAME}"): Debug: expunge: box=sa.spam uid=6657 doveadm("${USERNAME}"): Debug: expunge: box=sa.spam uid=6658 doveadm("${USERNAME}"): Debug: expunge: box=sa.spam uid=6659 doveadm("${USERNAME}"): Debug: expunge: box=sa.spam uid=6660 doveadm("${USERNAME}"): Debug: expunge: box=sa.spam uid=6661 doveadm("${USERNAME}"): Debug: expunge: box=sa.spam uid=6662 [...] If ran from cron, then the same uids show up every day, and new ones gets added (as new mails gets copied into those directories). Is there something fishy going on in doveadm-expunge if it has no controlling terminal?

[Dovecot] 2.0.2 : crashes with LDA
by Jakob Curdes 26 Oct '10

26 Oct '10

Hello, I just migrated to 2.0.2 and see some <xx(a)localhost.redirectme.net> (expanded from<xx@localhost>): Command died with signal 6: "/usr/local/libexec/dovecot/dovecot-lda -c /etc/dovecot2.conf". Command output: doveconf: Panic: file settings-parser.c: line 1838 (settings_copy_deflist_unique): assertion failed: (dest_count == ccount) doveconf: Error: Raw backtrace: /usr/local/lib/dovecot/libdovecot.so.0 [0x9395c0] -> /usr/local/lib/dovecot/libdovecot.so.0(default_fatal_handler+0x45) [0x9396b5] -> /usr/local/lib/dovecot/libdovecot.so.0 [0x938c78] -> /usr/local/lib/dovecot/libdovecot.so.0 [0x9183c7] -> /usr/local/lib/dovecot/libdovecot.so.0 [0x9182de] -> /usr/local/lib/dovecot/libdovecot.so.0(settings_parser_apply_changes+0x6f) [0x91849f] -> /usr/local/bin/doveconf(config_filter_parsers_get+0x25f) [0x804e8af] -> /usr/local/bin/doveconf(config_parse_file+0x6a8) [0x80502f8] -> /usr/local/bin/doveconf(main+0x21f) [0x804c43f] -> /lib/i686/nosegneg/libc.so.6(__libc_start_main+0xdc) [0x5c8e9c] -> /usr/local/bin/doveconf [0x804b291] This does not happen always; most mails get delivered normally through the LDA. A command line call of doveconf yields no problems. Any hints? Best regards, Jakob Curdes

[Dovecot] merge mdboxes
by Tobias Daucher 26 Oct '10

26 Oct '10

Hi there, after migration we have a very big problem... there are two mailboxes in /var/mail/username/mailboxes/ /var/mail/username/mailboxes/inbox /var/mail/username/mailboxes/inbox2 i DO have to merge these boxes, but i found no tools for this step. is there any way with doveadm oder dsync to move alle messages from mdbox inbox2 into mdbox inbox? i hope you all can tell me a way to do this - its a very very big problem at the moment. By the way - logging in via imap with thunderbird und move them on that way is not my favorite solution cause i have to do this for hundreds of users... i hope you can help me! thanks a lot!

I don't really know if there's much to do about this. I guess it could wait a second or so before disconnecting client to avoid it reconnecting back too fast.. > The client wasn't reconnecting as far as I can tell. It looked to me like the server process wedged after this error - we only got the error message logged once. The problem is that after it occurred no new clients could complete connections, but existing clients worked ok. Incoming connections were accepted, but then nothing would happen. As far as I can tell the parent would fork new child processes but they couldn't complete initialisation. Mail clients simply complained of a timeout during connection. This was affecting all users. With regard to error disconnections - yes a delay is a good idea.

[Dovecot] delivering mail to public mbox with permission 660?
by RParr 26 Oct '10

26 Oct '10

I am migrating a couple old RH servers running sendmail and UW-IMAP to a new Ubuntu 10.04 servers running Postfix and Dovecot. I have everything working reasonably well except that the permissions of newly created mbox mail folders is always 600. I have reviewed the archives, google, and double checked everything is as suggested in the Dovecot Wiki / SharedMailboxes / Permissions. I am running Ubuntu 10.04 packages postfix 2.7.0-1, dovecot-common, dovecot-imapd, dovecot-pop3d, and dovecot-postfix (all version 1.2.9-1ubuntu6.1). I plan to install amavisd-new, et.al. for spam filtering and anti-virus but have held off until I get Postfix and Dovecot working 100%. I have configured Postfix and Dovecot to use mbox mailboxes. I chose mbox becaus I have a LOT of shared mbox folders to migrate and decided it best to first migrate to Postfix/Dovecot mbox and later worry about migrating to maildir (as suggested on the Dovecot wiki mailbox format page). I have configured private (also as default) and public namespaces with the public mailboxes stored in /var/mail/public. /var/mail/public has rwxrws--- and is group tarts (the shared "company" group for this server). Initially I had procmail configured via the mailbox_command. Initial test mail sent to user tarts triggered creation of /var/mail/tarts with 660 permissions as expected. I then changed the configuration to use deliver via the mailbox_command. I did this because procmail appears to be unmaintained and to benefit from deliver's support for indexing at time of delivery and seive. I then added user testuser with primary group testuser and supplemental group tarts. I made sure testuser's home directory and mail sub dir had rwxrws--- permissions. I sent test mail to user testuser and had both user tarts and user testuser create some subfolders in public (via Thunderbird accounts) THE PROBLEM is that mbox folders that hold messages are created with permssion 600. My understanding, from the Dovecot wiki and other docs/postings is that the folders should be 660 given the /var/mail permssions of rwxrwsrwt and ~/mail permssions of rwxrws--- MY QUESTION is how do I correct the configuration and/or directory permissions so that mbox folders and .imap indices (especially public/ ones) are created with 660 permissions thus allowing users who belong to a common group (eg tarts) to access the public mailboxes? It appears all Dovecot configuration options to establish directory/box perms or mask, such as umask, have been deprectated and no longer work. The primary option appears to be using the permissions yet that is not working for me here. ----------------------------------- /home/: drwxrws--- 4 tarts tarts 4096 2010-10-19 13:59 tarts/ /home/tarts: drwxrws--- 4 tarts tarts 4096 2010-10-19 13:50 mail/ ----------------------------------- /d/home/: drwxrws--- 4 testuser testuser 4096 2010-10-19 13:59 testuser/ /d/home/testuser: drwxrws--- 4 testuser testuser 4096 2010-10-19 13:59 mail/ /d/home/testuser/mail: total 20 drwxrws--- 4 testuser testuser 4096 2010-10-19 13:59 ./ drwxrws--- 3 testuser testuser 4096 2010-10-19 13:44 ../ drwxrws--- 3 testuser testuser 4096 2010-10-19 13:45 .imap/ -rw-rw---- 1 testuser testuser 36 2010-10-19 13:59 .subscriptions -rw------- 1 testuser testuser 0 2010-10-19 13:50 Trash drwxrws--- 2 testuser testuser 4096 2010-10-19 13:54 test1/ -rw------- 1 testuser testuser 0 2010-10-19 13:54 test2 /d/home/testuser/mail/.imap: total 12 drwxrws--- 3 testuser testuser 4096 2010-10-19 13:45 ./ drwxrws--- 4 testuser testuser 4096 2010-10-19 13:59 ../ drwx--S--- 2 testuser testuser 4096 2010-10-19 13:50 INBOX/ /d/home/testuser/mail/.imap/INBOX: total 24 drwx--S--- 2 testuser testuser 4096 2010-10-19 13:50 ./ drwxrws--- 3 testuser testuser 4096 2010-10-19 13:45 ../ -rw------- 1 testuser testuser 16384 2010-10-19 14:00 dovecot.index.cache -rw------- 1 testuser testuser 864 2010-10-19 14:00 dovecot.index.log /d/home/testuser/mail/test1: total 8 drwxrws--- 2 testuser testuser 4096 2010-10-19 13:54 ./ drwxrws--- 4 testuser testuser 4096 2010-10-19 13:59 ../ -rw------- 1 testuser testuser 0 2010-10-19 13:54 sub1 ----------------------------------- /var: drwsrwsrwt 3 root mail 4096 2010-10-18 10:23 mail/ /var/mail: total 896 drwsrwsrwt 3 root mail 4096 2010-10-19 13:51 ./ drwxr-xr-x 16 root root 4096 2010-03-05 13:57 ../ -rw-rw---- 1 nobody mail 1386 2010-10-12 16:54 nobody drwsrws--- 5 root tarts 4096 2010-10-19 13:51 public/ -rw-rw---- 1 tarts mail 894107 2010-10-19 08:59 tarts -rw------- 1 testuser mail 632 2010-10-19 13:51 testuser /var/mail/public: total 24 drwsrws--- 5 root tarts 4096 2010-10-19 13:51 ./ drwsrwsrwt 3 root mail 4096 2010-10-19 13:51 ../ drwxrws--- 3 tarts tarts 4096 2010-10-19 13:51 .imap/ drwxrws--- 3 tarts tarts 4096 2010-10-16 15:02 test1/ drwxrws--- 2 tarts tarts 4096 2010-10-16 15:01 test2/ -rw------- 1 testuser tarts 633 2010-10-19 13:51 test3 /var/mail/public/.imap: total 12 drwxrws--- 3 tarts tarts 4096 2010-10-19 13:51 ./ drwsrws--- 5 root tarts 4096 2010-10-19 13:51 ../ drwx--S--- 2 testuser tarts 4096 2010-10-19 13:51 test3/ /var/mail/public/.imap/test3: total 28 drwx--S--- 2 testuser tarts 4096 2010-10-19 13:51 ./ drwxrws--- 3 tarts tarts 4096 2010-10-19 13:51 ../ -rw------- 1 testuser tarts 16384 2010-10-19 13:51 dovecot.index.cache -rw------- 1 testuser tarts 628 2010-10-19 13:51 dovecot.index.log /var/mail/public/test1: total 16 drwxrws--- 3 tarts tarts 4096 2010-10-16 15:02 ./ drwsrws--- 5 root tarts 4096 2010-10-19 13:51 ../ drwxrws--- 3 tarts tarts 4096 2010-10-16 15:02 .imap/ -rw------- 1 tarts tarts 614 2010-10-16 15:02 sub1 -rw------- 1 tarts tarts 0 2010-10-16 15:01 sub2 /var/mail/public/test1/.imap: total 12 drwxrws--- 3 tarts tarts 4096 2010-10-16 15:02 ./ drwxrws--- 3 tarts tarts 4096 2010-10-16 15:02 ../ drwx--S--- 2 tarts tarts 4096 2010-10-16 15:02 sub1/ /var/mail/public/test1/.imap/sub1: total 12 drwx--S--- 2 tarts tarts 4096 2010-10-16 15:02 ./ drwxrws--- 3 tarts tarts 4096 2010-10-16 15:02 ../ -rw------- 1 tarts tarts 408 2010-10-16 15:02 dovecot.index.log /var/mail/public/test2: total 8 drwxrws--- 2 tarts tarts 4096 2010-10-16 15:01 ./ drwsrws--- 5 root tarts 4096 2010-10-19 13:51 ../ Any help would be greatly appreciated.

26 Oct '10

http://dovecot.org/releases/2.0/dovecot-2.0.6.tar.gz http://dovecot.org/releases/2.0/dovecot-2.0.6.tar.gz.sig * Pre-login CAPABILITY includes IDLE again. Mainly to make Blackberry servers happy. * auth: auth_cache_negative_ttl default was 0 in earlier v2.0.x, but it was supposed to be 1 hour as in v1.x. Changed it back to 1h. If you want it disabled, make sure doveconf shows it as 0. + dbox: Added support for saving mail attachments to external files, with also support for single instance storage. This feature hasn't had much testing yet, so be careful with it. + doveadm: Added import command for importing mails from other storages. + Reduced NFS I/O operations for index file accesses + dbox, Maildir: When copying messages, copy also already cached fields from dovecot.index.cache + mdbox: Added mdbox_preallocate_space setting (Linux+ext3/XFS only) - Maildir: LDA/LMTP assert-crashed sometimes when saving a mail. - Fixed leaking fds when writing to dovecot.mailbox.log. - Fixed rare dovecot.index.cache corruption - IMAP: SEARCH YOUNGER/OLDER wasn't working correctly

[Dovecot] 2.0.3 Bug - hanging issue
by Alan Brown 25 Oct '10

25 Oct '10

We had this this morning: Oct 25 12:36:34 msslat dovecot: imap(keh2): Error: user keh2: Initialization failed: Namespace '#mbox/': mkdir(/stage/mail/imap1/keh2/mail) failed: Permission denied (euid=2291(keh2) egid=101(luci) missing +w perm: /stage/mail/imap1, euid is not dir owner) Oct 25 12:36:34 msslat dovecot: imap(keh2): Error: Invalid user settings. Refer to server log for more information. Oct 25 12:36:35 msslat dovecot: imap-login: Login: user=<keh2>, method=PLAIN, rip=128.40.73.160, lip=128.40.73.13, mpid=26736 Oct 25 12:36:35 msslat dovecot: imap(keh2): Error: user keh2: Initialization failed: Namespace '#mbox/': mkdir(/stage/mail/imap1/keh2/mail) failed: Permission denied (euid=2291(keh2) egid=101(luci) missing +w perm: /stage/mail/imap1, euid is not dir owner) Oct 25 12:36:35 msslat dovecot: imap(keh2): Error: Invalid user settings. Refer to server log for more information. Because the parent directory was rwxr-xr-x root.root The problem is that for some reason dovecot then wedged and a lot of other stuff piled up behind it, causing people to complain their mail wasn't coming through. Load average climbed to over 100. Creating the user directories freed things up...
