[Dovecot] Feature request: 'dovecot-shared' files to be configurable
by Hendrik Pahl 24 Sep '09

24 Sep '09

Hi list, using dovecot in a more complex environment nearly always requires use of ACLs and shared mailboxes/folders. Now, to make life more easy for the users, we can use 'dovecot-shared' files to eable per-user \seen-flagging. Is it possible to make this issue configurable in the dovecot config, something like "always keep a 'dovecot-shared' file in users maildir, even if that mailbox is not shared"? That would be nice, since creating that files by hand is really time-consuming. Or are there any relations which avoid making this issue configurable?

[Dovecot] Upgrading Dovecot on CentOS 4, from 0.99 to 1.x
by Josep L. Guallar-Esteve 24 Sep '09

24 Sep '09

Hello, We have a production mail server running dovecot 0.99 (dovecot-0.99.14-1.rf). We are getting several errors corrected in dovecot 1.x versions: * corrupted inboxes (garbage at beggining of mbox files), * corrupted index files (Error: Corrupted file index /home/jsmith/.imap/Drafts/.imap.index: Sequence 6 not found from binary tree (6 msgs says header)), * others (Error: fcntl() failed with mbox file /var/mail/jsmith: Resource deadlock avoided), etc. I'm planning to upgrade using the instructions found at dovecot's wiki. -- Josep L.

[Dovecot] Dovecot LDA, quota, sieve
by Jacek Osiecki 24 Sep '09

24 Sep '09

Hi, While moving services to a new server, I finally decided to switch from exim + procmail delivery to exim + dovecot-LDA (dovecot 1.2.5). All accounts are virtual - their settings are stored in mysql. This also includes configuring Quota and Sieve. So... there come some doubts: 1. Using "deliver" As I see, deliver uses auth-master socket to retrieve the mailbox settings (especially mailbox location). So, enabling dovecot-auth socket is everything I need to enable dovecot-LDA (apart from the exim configuration, which is explained quite clearly in wiki)? 2. Autocreation of mail folders Is it possible somehow to automatically create folders (like Trash, Sent-mail etc.)? 3. quota and its dict file. map { pattern = priv/quota/storage table = popbox username_field = username value_field = bytes } map { pattern = priv/quota/messages table = quota username_field = username value_field = messages } First - what is the "username_field" here? I'm running multiple domains, so will it be just username@domain? And - if so - is it possible to use the existing tables? I mean, that in my configuration I have a table named "popbox" with fields "local_part", "domain_name" and "quota". It would be perfect to make use of it, but either I could not find the solution or it simply requires an extra table... Hope someone will be able to help :) Best regards, -- Jacek Osiecki joshua(a)ceti.pl GG:3828944 I don't want something I need. I want something I want.

[Dovecot] windows imap clients
by Charles Sprickman 23 Sep '09

23 Sep '09

All, This is slightly OT, but I figure a bunch of folks running IMAP servers should have some strong opinions on the topic. While working on a migration to Dovecot, I had the opportunity to move one account to a server running same. This is an in-house billing department box that 3-4 people share. In theory, this should work well - all the billing folks see the same email, save sent mail to the same place, have the same set of folders available, and concurrent access is no problem. In practice, I'm finding most clients kind of suck. They started with Outlook, and that did not work well. The list of problems is long. They've been using Thunderbird for some time and I'm finding the following issues there: -searches across 2GB+ of mail are painfully slow, since it's all server-side -while the inbox is checked regularly and automatically, other folders are not unless the user manually checks them. getting tbird to do this involves a fairly non-intuitive process, and there's also the issue of making sure everyone actually adds the folders they need to watch -the client does not deal well with large amounts of mail in general - some operations give no feedback, like expanding large sub-folders or doing large copy/move operations. this leads to the user quitting the app and starting the whole process again. dovecot deals with this more gracefully than the old server (Courier), but it's still an issue -offline operation would be handy sometimes, but tbird has no "hybrid" mode, and again, one must select every folder for offline access As much as people like to bash it, OS-X mail.app is basically what I'm looking for. It addresses all the shortcomings in Tbird. If I tell it to make messages available offline, it does that for all boxes. It always checks all my boxes, and when a search is performed it searches on the local copy rather than the server (which is quite polite, IMHO). It works quite well with no internet connection as well. I have about 50,000 messages in it now across 5 accounts and it only rarely gets laggy on me. I want this client on Windows, basically. :) I'm installing Mulberry now, but the manual seems to indicate it also will rely on the server-side search unless it's in offline mode (which has to be toggled - not a good solution). I must say, Dovecot has impressed the hell out of me. I had a chance to deal with the same mailbox in courier and dovecot, and everything is much faster, especially in mail.app and roundcube. Insanely fast... What else is out there for windows clients? Thanks, Charles ___ Charles Sprickman NetEng/SysAdmin Bway.net - New York's Best Internet - www.bway.net spork(a)bway.net - 212.655.9344

[Dovecot] Solr Plugin make only INBOX able to search
by rui.carneiro＠portugalmail.net 23 Sep '09

23 Sep '09

Hi all, I have downloaded and installed dovecot 1.2.4 with Solr plugin. After that, when I try to do some searches the results are weird. All messages that aren't on INBOX folder are ignored. For example, if I have a folder named "Test Folder", when I try to do ". search text <string>" the result is always empty. I tried TEXT, SUBJECT and BODY arguments and none of them returned any email. Any idea of the problem's source? Regards, Rui Carneiro

[Dovecot] SharedMailboxes in a distributed environment
by Christian Rohmann 23 Sep '09

23 Sep '09

Hello folks, I'd like your thoughts on the following problem: If one is using v1.2+ IMAP ACLs to allow users to share their mailbox and uses SQL as dictionary backend, every dovecot server would know which ACLs to enforce. But as the wiki states here "http://wiki.dovecot.org/SharedMailboxes/Shared" dovecot needs access to the other mailbox. Does that automatically mean that one dovecot machine needs to have filesystem access to the all mailboxes that are to be shared? Is there no way to share mailboxes (folders) between different servers? (apart from using NFS i.e.) -- Christian Rohmann Content Delivery Server u.

[Dovecot] shared/public mailbox doesn't exist
by Eric Shubert 22 Sep '09

22 Sep '09

I have 3 servers running dovecot 1.0.10. 2 of them are configured with a shared/public namespace, but I'm having trouble getting it to work on the third, even with 2 working examples to go by. There's something I'm missing, and I'm hoping that someone here can see/tell what it is. I've created the maildir for sharing: # cd /home/vpopmail/domains/mydomain.com # maildirmake shared # chown -R vpopmail:vchkpw shared Then added the configuration to dovecot.conf: # shared namespace namespace shared { separator = . prefix = shared. location = maildir:/home/vpopmail/domains/mydomain.com/shared } Restarted dovecot: # service dovecot restart When I try to subscribe to the shared namespace though with Outlook, I get: "Failed to subscribe the folder. Server responded: 'Mailbox doesn't exist: shared'." When I try to subscribe with Squirrelmail I get: "ERROR: Could not complete request. Query: SUBSCRIBE "shared" Reason Given: [TRYCREATE] Mailbox doesn't exist: shared" I've tried various combinations of permissions to no avail. Suggestions welcome. I'm at my wits end. -- -Eric 'shubes'

[Dovecot] Dovecot versions and index compatibility
by Steven F Siirila 22 Sep '09

22 Sep '09

I realize these are older versions, but I'd like to know specifically whether dovecot 1.1.6 and dovecot 1.1.8 are compatible index-wise. In particular, if we downgraded from 1.1.8 to 1.1.6 would there be any issues with doing so? I realize there are later versions, but we've tested both of the above extensively, but recently loaded up a server with 1.1.8 and found that the 'imap' process core dumps frequently, so before we pursue later versions we thought it would be best to downgrade to 1.1.6. -- Steven F.

[Dovecot] Managesieve displays folder name (dovecot/sieve)
by Seba 21 Sep '09

21 Sep '09

Hi, I'm using Dovecot 1.2.4 with ManageSieve 0.11.9 and Sieve. All works fine but users can subscribe to the folder "dovecot/sieve" which is also displayed in the folders list. protocols = imap managesieve protocol managesieve { listen = ip_address:2000 managesieve_logout_format = bytes ( in=%i : out=%o ) } plugin { sieve=~/Maildir/.dovecot.sieve sieve_dir=/home/vmail/%d/%n/Maildir } In the maildir of the user I see this folders and files: .Drafts/ .Sent cur/ new/ temp/ sieve/ @.dovecot.sieve ingo.sieve The file "ingo.sieve" comes from Horde Ingo because users manage their scripts with ingo.The symlink "dovecot.sieve" is correct and point to ingo.sieve. When users browse their available IMAP folders they'll see a folder "dovecot/sieve". Can this be turned off or restricted with acl's? Without an symlink all folders are displayed normally without the "dovecot sieve" folder. Thanks.

Now I change the first line in foo's maildirsize file to "0S" to allow unlimited quota. Then I boost it's size to force recalculation (just to be sure) dd if=/dev/zero bs=1k count=6 >> ~foo/Maildir/maildirsize - From now, TB still reports 20GB quota for user foo, the above "echo" command still reports 20971520, but(!), quota is actually unlimited for user foo. OK, now I stop dovecot, delete maildirsize, change line in dovecot.conf quota_rule = ?:storage=0 and start dovecot again. The same result - TB still reports 20GB quota for user foo, the above "echo" command still reports 20971520, but(!), quota is actually unlimited for anyone. When I set some limit in ~foo/Maildir/maildirsize now, same values 20971520) are reported, although the limit works! Looks like LDA (deliver) works fine, but imap_quota plugin is doing something weird. Finally, the question ;-) Where does that value (20971520) come from? Is it a feature or a bug? - -- David Kmoch -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkqfhQoACgkQsUUM+N2AWobj7ACgh3yCU9LVfe1Pp2lO0nBG9iKf zbgAn15UvkVM0AeCxaUlDeYgFu++8TOn =CAoG -----END PGP SIGNATURE-----

[Dovecot] plugin development guide for non-FS backing store
by Chang Song 21 Sep '09

21 Sep '09

Hi, folks. I was wondering if anyone has some sort of guide or reference on plugin development. We are trying to develop a non-filesystem backing store. So basically we do not store mailboxes for users in local filesystem. We do RPC call to fetch from fileservers. Thank you in advance. Chang

[Dovecot] Override quota rules based on mail's content
by Andreas Calvo Gómez 21 Sep '09

21 Sep '09

Hi, I've a mail server with Postfix and Dovecot, using a LDAP backend to get the users. I've also configure quota rules, and I'm able to get the quota from LDAP. But I need the mails that come from the local domain to bypass the quota rule and be delivered to the users' inbox. Is there any way to do that? Information required by Dovecot's mailing list rules: +++ dovecot.conf +++ # 1.1.11: /etc/dovecot/dovecot.conf # OS: Linux 2.6.28-15-server x86_64 Ubuntu 9.04 ext4 log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login login_user: postfix valid_chroot_dirs: /var/spool/dovecot first_valid_uid: 1000 first_valid_gid: 512 mail_privileged_group: mail mail_location: maildir:/var/spool/dovecot/%n/ mail_plugins: quota imap_quota imap_client_workarounds: delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep auth default: mechanisms: plain login default_realm: esci.es username_format: %Lu passdb: driver: pam passdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf userdb: driver: prefetch userdb: driver: passwd userdb: driver: ldap args: /etc/dovecot/dovecot-ldap-userdb.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: mail group: mail plugin: quota: maildir:User quota quota_rule: *:storage=50M quota_rule2: Trash:ignore +++ dovecot-ldap.conf +++ hosts = ldap.esci.es auth_bind = yes ldap_version = 3 base = ou=Users, dc=esci, dc=es scope = subtree user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid,mailQuota=quota_rule=*:storage=%$M user_filter = (&(objectClass=posixAccount)(|(mail=%u)(uid=%u)(uid=%n))) pass_attrs = uid=user,userPassword=password,\ homeDirectory=userdb_home,uidNumber=userdb_uid,gidNumber=userdb_gid,mailQuota=userdb_quota_rule=*:storage=%$M pass_filter = (&(objectClass=posixAccount)(|(mail=%u)(uid=%u))) default_pass_scheme = SSHA Thanks. --------------------- Andreas Calvo Gómez <andreas.calvo(a)admi.esci.es> Dept.

[Dovecot] Automatic fd limit changing
by Timo Sirainen 21 Sep '09

21 Sep '09

I just realized that Dovecot should probably be doing something different with how it handles fd limits. The way it currently works is: 1. It checks some settings and warns at startup if fd limit is lower than what master process might need. 2. For login processes it calculates how many fds are needed and then either increases or decreases it. So it's automatically and silently increasing fd limit for some processes, but not for others. Should it just automatically increase the limits to all processes when necessary, or never increase and just warn that the limit is too low?

[Dovecot] Sieve not fast enough after upgrade?
by Nikolay Shopik 21 Sep '09

21 Sep '09

I've upgraded mine Dovecot 1.0.15 to 1.2.4 also moved to new Sieve. I have simple sieve rule: if header :contains "Delivered-To" ["bcc(a)bcc.inblock.ru"] { setflag "\\Seen"; } It basically mark my own messages which are saved to Sent folder. When I was on 1.0.15 I never seen unread count in Thunderbird, but suddenly after upgrade I seen unread message in Sent folder just after I've sent message. If I open Sent folder it already marked as read. Me wonder if this is actually Dovecot much faster delivers and reports to MUA there is new unread message or Sieve not perform fast enough?

[Dovecot] Dovecot Sieve Vacation Messages
by Steven Murphy 20 Sep '09

20 Sep '09

I'm using a Postfix, Dovecot, MySQL setup with virtual domains. I have mail being delivered through Dovecot LDA working 100%. I'm trying to use sieve to handle vacation messages but dovecot is not reading the .dovecot.sieve file in the users maildir. I have a hunch it has to do with my dovecot-sql query but have had no success with what I found in the forums from Googling. Any help would be greatly appreciated.

[Dovecot] simple feature request: IMAP logged out message
by Leonardo Rodrigues 18 Sep '09

18 Sep '09

i'd like to make a simple feature request on dovecot .... i'm using v1.2.4 (latest one) and IMAP logout message, by default is: Sep 18 14:26:27 correio dovecot: IMAP(user(a)domain.com): Disconnected: Logged out bytes=384/932222 the message can be a little customized with: # IMAP logout format string: # %i - total number of bytes read from client # %o - total number of bytes sent to client imap_logout_format = bytes=%i/%o The remote IP address, the IP which the user is coming from, can only be seen on the login message: Sep 14 09:09:12 correio dovecot: imap-login: Login: user=<user(a)domain.com>, method=PLAIN, rip=187.6.xx.xx, lip=200.140.yy.yy the feature request is that the remote IP address could be added on the Logout message too, that would make much easier to watch connections from some specific user and from some specific ip address, regarding traffic of the connection. For example, something like: Sep 18 14:26:27 correio dovecot: IMAP(user(a)domain.com): Disconnected: Logged out bytes=384/932222, rip=187.6.xx.xx, lip=200.140.yy.yy -- Atenciosamente / Sincerily, Leonardo Rodrigues Solutti Tecnologia http://www.solutti.com.br Minha armadilha de SPAM, NÃO mandem email gertrudes(a)solutti.com.br My SPAMTRAP, do not email it

[Dovecot] IMAP clients suddenly redownload folder headers
by Brent Bloxam 18 Sep '09

18 Sep '09

We had an issue today with IMAP clients (Thunderbird, Outlook) having to redownload headers for folders. This issue was eerily close to a MySQL database structure change that shouldn't have affected any related queries, however we did notice an event of user CPU % not being reported via SNMP around the same time for the server. There are no entries in our dovecot error log around the outage. We're running Dovecot 1.1.13 with MySQL being used for user and password queries, and Maildir for storage on a fibre channel SAN. However, it is possible for some stores to be on an NFS mount (supporting legacy during migration), which is why there is the nfs options in the below config. I'm wondering if someone could shed light on what could cause this to occur. I imagine it's related to the index cache's, but the lack of any mention in the error logs has me puzzled. Output of dovecot -n: # 1.1.13: /usr/local/etc/dovecot.conf # OS: FreeBSD 7.0-RELEASE i386 base_dir: /var/run/dovecot log_path: /var/log/dovecot-error.log info_log_path: /var/log/dovecot-info.log protocols: imap pop3 ssl_disable: yes disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login mail_max_userip_connections: 100 first_valid_uid: 89 mail_privileged_group: 89 mail_uid: 89 mail_gid: 89 mail_location: maildir:~/Maildir mail_debug: yes mmap_disable: yes mail_nfs_storage: yes mail_nfs_index: yes lock_method: dotlock mail_executable(default): /usr/local/libexec/dovecot/rawlog /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/rawlog /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 pop3_uidl_format(default): %08Xu%08Xv pop3_uidl_format(imap): %08Xu%08Xv pop3_uidl_format(pop3): %f namespace: type: private separator: . prefix: INBOX. inbox: yes list: yes subscriptions: yes auth default: mechanisms: plain apop cache_size: 10240 cache_negative_ttl: 30 username_format: %Lu passdb: driver: sql args: /usr/local/etc/dovecot-sql.conf userdb: driver: sql args: /usr/local/etc/dovecot-sql.conf
