[Dovecot] Removing Duplicates
by Sabahattin Gucukoglu 23 Mar '10

23 Mar '10

Hi all, I am starting fresh with a local repository of mails, which almost certainly have duplicates in them. I am going to use maildirs, and ensure all mails are input with CRLFs. The question is: does anybody know how I can find and remove duplicates, either while injecting mail with IMAP, or afterward? I can use tools to find duplicate Message-IDs, but don't know of a way to remove duplicates in mailboxes that are already imported as opposed to incoming mail. Perhaps there is a way to use the IMAP protocol for this? Cheers, Sabahattin

[Dovecot] Debian Unstable Packages
by Sabahattin Gucukoglu 23 Mar '10

23 Mar '10

Hi all, Speaking of Debian, what relative position are the Debian Unstable (Sid) packages in to the latest "Bleeding edge" builds of RCS-based releases from the Wiki? If using Unstable is it recommended to stay or use the newer ones? I'd say it was production, yes, but I'm forgiving of problems in the latest releases, so long as they aren't meant to be beta (i.e., known breakages). Cheers, Sabahattin

Hi, I've been able to configure --with-mysql in Solaris 10 which has MySQL version 4.0.31 bundled in. Since beta4 build fails due to change in src/lib-sql/driver-mysql.c. I've never used this feature but so I don't need it. This is just a FYI if someone reads mailing list.

[Dovecot] Shared mailboxes basics
by Thomas Hummel 22 Mar '10

22 Mar '10

Hello Timo, I'm trying to set up shared mailboxes with dovecot-1.2.11/Maildir. I previsouly used public namespaces with 1.1+ to somehow implement them but I'm looking at the real ones now. I've read the Wiki but I'm still confused or not 100% sure about the following (basic) points : 1. Namespaces prefixes My understanding is that a namespace prefix is just an escape mechanism for the client to access the mailboxes this namespace holds. So the real location is _only_ defined by the "location" directive, independently of what the prefix is. So, for example, If you've got : prefix="foo/bar/" location=maildir:/some/folder/%u mailboxes are physically in /some/folder/%u, not in /foo/bar/some/folder/%u or something am I correct ? 2. Other Users mailboxes RFC234 states that shared mailboxes (which they call "Other Users" mailboxes) are "mailboxes from the Personal Namespaces of other users." Dovecot's Wiki takes as an example : # User's private mail location. mail_location = maildir:~/Maildir # You need to create also a private namespace: namespace private { separator = / prefix = #location defaults to mail_location. inbox = yes } namespace shared { separator = / prefix = shared/%%u/ location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u subscriptions = no list = children } and states : "This creates a shared/ namespace under which each user's mailboxes are." My understanding is that # User's private mail location. mail_location = maildir:~/Maildir and location = maildir:%%h/Maildir implies that mailboxes in both the private and the shared/ namespace are physically in the same location (under the "$HOME/Maildir" directory of the user who shares his mailbox) . Am I correct ? I tried the following set up : namespace private { separator = / location = maildir:/courriel/boites/%u:CONTROL=/courriel/meta/%u:INDEX=/var/dovecot-test/indexes/%1u/%u inbox = yes hidden = no list = yes subscriptions = yes } namespace shared { separator = / prefix = "#shared/%%u/" location = maildir:/courriel/boites/%%u:INDEX=/var/dovecot-test/indexes/%1u/%u/shared/%%u subscriptions = no list = yes # will try children later } the user doveimap has the following mailboxes : # pwd /courriel/boites # ls -l doveimap total 64 drwx------ 5 doveimap Invites 4096 Oct 23 13:38 .Trash drwxr-xr-x 5 doveimap Invites 4096 Oct 27 17:00 .sous drwxr-xr-x 5 doveimap Invites 4096 Oct 27 17:00 .sous.arbo drwxr-xr-x 5 doveimap Invites 4096 Oct 27 17:00 .sous.arbo.rescence drwx------ 5 doveimap Invites 4096 Oct 23 13:43 .testcopy drwx------ 2 doveimap Invites 4096 Mar 15 17:08 cur drwx------ 2 doveimap Invites 4096 Mar 15 17:07 new drwx------ 2 doveimap Invites 4096 Mar 15 17:07 tmp I can perform for instance : * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE STARTTLS AUTH=PLAIN] Dovecot test ready. x login doveimap xxxxxxxx x OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT IDLE CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS ACL RIGHTS=texk] Logged in 1 setacl INBOX dovepop rl 1 OK Setacl complete. But isn't a client like Thunderbird (3.0.3) supposed to . show me the #shared (even if no one shares mailboxes to me) "folder" (because of list = yes )? . let me share, let's say the .sous.arbo mailbox ? If yes, how ? Or should I first pre-set some acl files ??? For now, it says : "This is a personnal mail folder. It is not shared."

[Dovecot] dovecot-2.0.beta3 tcpwrapper support in Solaris
by Tomi Vainio 22 Mar '10

22 Mar '10

Hi, 2.0 compiles fine in Solaris but and I've found only one glitch so far. Tcpwapper support needs some tweaks. I need to add CPPFLAGS=/usr/sfw/include because tcpd.h is in there. Then also LDFLAGS='-R/usr/sfw/lib -L/usr/sfw/lib' is needed. It would be nice to have --with-tcpwrap-dir or something. After this linking gives an error Undefined first referenced symbol in file deny_severity /usr/sfw/lib//libwrap.so allow_severity /usr/sfw/lib//libwrap.so These are not defined but application itself should define these globally so I've added these to configure and src/util/tcpwrap.c #include <syslog.h> int allow_severity = LOG_INFO; int deny_severity = LOG_WARNING; Tomppa

[Dovecot] Dovecot 1.2.11 renames Maildir filenames on first read of foreign POPstore - how to avoid
by Sam C. Nicholson !! 22 Mar '10

22 Mar '10

Greetings, I'm converting from a custom POPstore ( > 100,000 messages) which is Maildir-like and uses the filename as the UIDL and doesn't store it inside the message. I'm wondering whether there is hope for config-file options to keep devecot from renaming files when it first sees them, or whether I'm going to need to create a new backend for dovecot based on Maildir. The renaming not only blows my current UIDLs, it seems to upset Dovecot's indexing, Cheers! -sam My POPstore looks like this: /zdata/domain/%d/folders/%n/{cur, new, tmp}/ and message filenames like this: msg.yyyy:mm:dd:hh:mm:ss.random I was able to get Dovecot to see the store by the symlink: INBOX -> . Here are the log messages regarding the index warnings: Mar 22 07:45:52 POP3(scion(a)6ix.net): Warning: Fixed a duplicate: /zdata/domain/6ix.net/folders/scion/INBOX/cur/msg.2008:02:20:16:37:56.951.2376 -> 1269258346.M323507P15988.mailbase Mar 22 07:45:52 POP3(scion(a)6ix.net): Warning: Fixed a duplicate: /zdata/domain/6ix.net/folders/scion/INBOX/cur/msg.2008:01:08:00:00:50.25142.18396 -> 1269258346.M323508P15988.mailbase ^ |____Dovecot message name appears to increment here #dovecot -c config -n # 1.2.11: /home/scion/Packages/dovecot-1211/dovecot.conf.short Warning: fd limit 256 is lower than what Dovecot can use under full load (more than 640).

[Dovecot] configure dovecot to read-only ?
by Frank Gadegast 22 Mar '10

22 Mar '10

Hi, I like to configure the use of IMAP to read-only on a special backup system. Users should only be able to read archived email, they should not be able to create folders or delete email. I know how to configure user- or folder-specific acls, but it seems to be a bit complicated to setup a ACL for every user. Any simple global option available ?

[Dovecot] Possible programming error in maildir_mail_get_save_date
by Rainer Weikusat 22 Mar '10

22 Mar '10

The maildir_mail_gate_save_date routine (lib-storage/index/maildir/maildir-mail.c) returns the save date when that was determined by looking at the ctime of the corresponding file. This is different from all other get_save_date routines which either return -1 if the date could not be determined or 0 to signal success. A particular problem caused by this would be that the first_nonexpunged_timestamp routine (plugins/expire/expire-plugin) never finds a not-yet-expired e-mail after the first message in a mailbox has been expunged when using the maildir storage and file ctimes for save dates, causing the expire_mailbox_transaction_commit function (same file) to delete expiry information for the mailbox in question from the expires table despite mails supposed to expire still exist.

[Dovecot] Public Folder for mailinglist with deliver
by Sebastian Heil 21 Mar '10

21 Mar '10

Hello Everybody, I'm looking for a nice way to implement the following: We are running a mail server for system users who are having their own mailbox. Now there's the idea to subscribe for a few mailinglists which are then available for the user per shared/public folder. So they can simply subscribe and unsubscribe with their MUA. For every mailinglist subscription there should exist an own email account with own mail directory. The namespaces are already working (in a test environment). But I haven't found any implementation to realize this nicely with deliver. The possiblities I'm thinking about are: -create a somewhere in userdb a passwd entry for each mailinglist email address with the corresponding directory -create a static userdb entry, but then deliver cannot check if an email address/mailbox exists. I think both ideas aren't a good implementation. So I'm asking you for help. Has someone a similar setup or a little idea how to make this work with deliver. Thanks in advance Sebastian

[Dovecot] Sendmail + deliver; silent errors.
by Daryl Tester 20 Mar '10

20 Mar '10

Hi all. I've got a bit of a peculiar issue here. I'm running dovecot 1.2.9 on an Ubuntu 9.10 box using Sendmail 8.14.3. I've set up Sendmail similar to <http://wiki.dovecot.org/LDA/Sendmail> except that *) dovecot's deliver is configured as my default local mailer, so some of the flags for the Mailer definition had to be adjusted accordingly. *) The setuid users listed in the wiki kept result in setgid() failures from deliver, so I've changed it to root:mail (mail being sendmail's MDA group), with permissions as u+s,g+rx,o-rwx When sendmail attempts delivery, I'm getting "deferred: deliver failed with EX_TEMP", but nothing recorded in the log files. I've embarrassingly widened the permissions of /var/log/dovecot and the files contained within to read/write everyone, just to ensure that whomever it's running as has access, but the log files aren't updated. The peculiar thing kicks in when I attempt to debug this. So far I have (amongst other things): *) Run deliver from the command line logged in as "mail". *) written a shell wrapper script to be able to confirm things like the user ID that was invoking deliver. *) both in the shell script, and as an mailer definition in sendmail, strace'd (using a setuid root binary) deliver to capture what it was doing. Whenever I do any of the above, deliver works perfectly, and appears to log correctly. It only appears to bork when no-one is watching it, which is quite frustrating when trying to fix it. Help? Configuration of dovecot follows: # 1.2.9: /etc/opt/dovecot-1.2.9/dovecot.conf # OS: Linux 2.6.31-14-server x86_64 Ubuntu 9.10 ext3 base_dir: /var/run/dovecot-1.2.9/ log_path: /var/log/dovecot/dovecot.log info_log_path: /var/log/dovecot/dovecot-info.log protocols: pop3 imap imaps ssl: no disable_plaintext_auth: no login_dir: /var/run/dovecot-1.2.9//login login_executable(default): /opt/dovecot-1.2.9/libexec/dovecot/imap-login login_executable(imap): /opt/dovecot-1.2.9/libexec/dovecot/imap-login login_executable(pop3): /opt/dovecot-1.2.9/libexec/dovecot/pop3-login mail_uid: vmail mail_gid: vmail mail_location: maildir:/vmail/spool/%u:LAYOUT=fs mail_executable(default): /opt/dovecot-1.2.9/libexec/dovecot/imap mail_executable(imap): /opt/dovecot-1.2.9/libexec/dovecot/imap mail_executable(pop3): /opt/dovecot-1.2.9/libexec/dovecot/pop3 mail_plugin_dir(default): /opt/dovecot-1.2.9/lib/dovecot/imap mail_plugin_dir(imap): /opt/dovecot-1.2.9/lib/dovecot/imap mail_plugin_dir(pop3): /opt/dovecot-1.2.9/lib/dovecot/pop3 lda: postmaster_address: postmaster(a)handcraftedcomputers.com.au auth_socket_path: /var/run/dovecot-1.2.9/auth-master auth default: verbose: yes passdb: driver: passwd-file args: /vmail/auth/passwd userdb: driver: static args: uid=vmail gid=vmail socket: type: listen master: path: /var/run/dovecot-1.2.9/auth-master mode: 384 user: vmail group: vmail -- Regards, Daryl Tester Member of the Amalgamated Australian Association Against Apostrophe Abuse.

[Dovecot] Dovecot v2.0.beta3 quota using userdb
by e-frog 20 Mar '10

20 Mar '10

Hello Timo, I'm playing around with the new Dovecot v2.0.beta3 and don't seem to be able to get quotas working from userdb. I didn't change the SQL query which was working for 1.2.10.

[Dovecot] INBOX of a shared namespace appears to be always subscribed
by Holger Richter 20 Mar '10

20 Mar '10

In dovecot 1.2.10 I run into the following problem: Our users are entitled to share their personal mailboxes. This works. But if user A shares any of its mailboxes with user B, then dovecot always reports the INBOX of user A as subscribed by user B. No matter whether user B really subscribed the INBOX of A, or whether user A permitted user B the access to its INBOX. The problem is caused by the repeated call of LSUB. Starting with the second call LSUB always shows INBOX as subscribed. To reproduce: -> telnet imap.xx.yy 143 1 LOGIN user password 2 LSUB "" shared/* => shows shared/UserB/folderXX 3 LSUB "" shared/* => shows shared/UserB/INBOX shared/UserB/folderXX 4 LSUB "" shared/* => shows shared/UserB/INBOX shared/UserB/folderXX Regards, Holger

[Dovecot] problem with master db and dovecot-2.0.beta3
by Oliver Eales 19 Mar '10

19 Mar '10

Hello, i am currenty testing dovecot 2.0.beta3 and ran into a problem with the master-db setting. For our webmail access we are sucessfully using the following settings with dovecot-1.2.10 auth_master_user_separator =* auth default { mechanisms = plain passdb passwd-file { args = /etc/dovecot/passwd.masterusers master = yes pass = yes } passdb ldap { args = /etc/dovecot/dovecot-ldap.conf } } when "converting" the settings to version 2.0 i tried the following: auth_mechanisms = plain auth_master_user_separator = * passdb { driver = passwd-file args = /etc/dovecot/passwd.masterusers master = yes pass = yes } passdb { driver = ldap args = /etc/dovecot/dovecot-ldap.conf } But when i try to login, the auth process gets stalled with the following log entry: auth: Fatal: Master passdb can't have pass=yes if there are no passdbs master: Error: service(auth): command startup failed, throttling Am i doing something wrong or is it problem with the 2.0-beta ?

[Dovecot] Triggering mailbox fetch
by Brian Candler 19 Mar '10

19 Mar '10

Greetings, I would like to migrate mailboxes into a Dovecot system by using an IMAP transfer from the old system - and I'd like this to take place automatically at the time the user first logs into the new system. I have a script which will perform an IMAP fetch and dump it into the local maildir. In courier-imap I could create a '.loginexec' file which is executed when the user logs in, and gets deleted if it completes successfully. I'm trying to find something similar for Dovecot. * fetchmail-wakeup is the right kind of idea, but I need it to stop running once mail has been transferred successfully once. It also needs different parameters for each user (e.g. user/pass used to login to the remote IMAP server) * The convert_mail plugin only works with local mail spools, as far as I can tell. I'm not sure how it determines whether conversion has already taken place (whether the target maildir already exists?) * autocreate only creates empty mailboxes Any of these might be a starting point for developing my own plugin, but does anyone here know of an existing one which would do the job? Thanks, Brian.

[Dovecot] Problem with quota recreation
by Uroš Gruber 19 Mar '10

19 Mar '10

Hi, I'm migrating from cyrus to dovecot 1.2.10 with cyrus2dovecot. I've setup quota with mysql dict and while testing delivery quota is working fine. The only problem is when i migrate mailbox from cyrus to dovecot and when bytes and messages is set to 0. I tried with x GETQUOTAROOT Inbox but the quota usage is not recalculated and when a new message is delivered quota is calculated only on the new message. Any help would be greatly appreciated. Best regards Uros

[Dovecot] ACL + shared-imap + nested AD groups
by Martin Ott 19 Mar '10

19 Mar '10

Hi, I'm looking for a solution to use nested AD groups for authorization in shared-imap folders(namespace public). As a simple hack to determine the (primary) groups of a user we use the following setup with a post-login script: in dovecot.conf ... protocol imap { mail_executable = /etc/dovecot/ldap_groups.sh ... ldap_groups.sh ACL_GROUPS=`ldapsearch -h ldapserver -p 3268 -s sub -D "cn=ldap mail, ou=user, ou=global, ou=xxx, dc=xxx, dc=local" -b "ou=xxx, dc=xxx, dc=local" "(&(sAMAccountName=$USER))" -LLL memberOf -w password | grep "memberOf: CN=" | sed 's/memberOf: CN=//' | sed 's/,OU=.*//' | tr "\n" "," | sed 's/, $//'` export ACL_GROUPS exec /usr/libexec/dovecot/imap $* Does anyone know, how to simply get the groups of groups with such a post-login script? Thanks, Martin

[Dovecot] 2.0beta3 10876:370ee9717a6c broke listen on literal IPv6 address
by Bernhard Schmidt 19 Mar '10

19 Mar '10

Hi, apparently the following change in dovecot hg * New revision (10876:370ee9717a6c) in dovecot Mercurial repository: - config: Forgot to add header file. broke listen = 83.170.6.69, 2001:1b10:1000::110:1:1 mail.svr02.mucip.net:~# dovecot -F -c /etc/dovecot/dovecot.conf doveconf: Warning: Obsolete setting in /etc/dovecot/dovecot.conf:29: listen=..:port has been replaced by service { inet_listener { port } } doveconf: Fatal: Error in configuration file /etc/dovecot/dovecot.conf: duplicate listener: 1: Is this even possible? That doesn't make sense to me, but Stephan's +29 works fine for me, +30 (with just that change according to changelog) doesn't. Bernhard

[Dovecot] GlusterFs - Any new progress reports?
by Ed W 18 Mar '10

18 Mar '10

GlusterFs always strikes me as being "the solution" (one day...). It's had a lot of growing pains, but there have been a few on the list had success using it already. Given some time has gone by since I last asked - has anyone got any more recent experience with it and how has it worked out with particular emphasis on Dovecot maildir storage? How has version 3 worked out for you? Anyone had success using some other clustered/HA filestore with dovecot who can share their experience? (OCFS/GFS over DRBD, etc?) My interest is more in bootstrapping a more highly available system from lower quality (commodity) components than very high end use Thanks Ed W

Re: [Dovecot] sieve vacation
by Martin F. Foster 18 Mar '10

18 Mar '10

Following from Steffen Kaiser's response, RFC5230 explains the conditions necessary for the Sieve Vacation extension to trigger a response. This says: "Vacation" MUST NOT respond to a message unless the recipient user's email address is in a "To", "Cc", "Bcc", "Resent-To", "Resent-Cc", or "Resent-Bcc" line of the original message. So your scenario 4 happens when the sender is only in the envelope, and not in the headers. For example: this transaction will get a response because the mailbox address is in the To: header ehlo there.com mail from: <dude(a)there.com> rcpt to: <user(a)domain.tld> << envelope recipient, mailsystem routes with this information data To: "Some User" <user(a)domain.tld> << header recipient must be correlated for Sieve Vacation to send a response From: "Dude" <dude(a)there.com> Subject: message Hi there . This transaction will not get a response, and will trigger the "discarding vacation response for message implicitly delivered to <user(a)domain.tld> " log: ehlo there.com mail from: <dude(a)there.com> rcpt to: <user(a)domain.tld> data Subject: message Hi there .

Perhaps it is installed by default on linux, but probably not on all other platforms. Why not just include the UnicodeData.txt file? Best Regards

[Dovecot] v1.2.11 released
by Timo Sirainen 18 Mar '10

18 Mar '10

http://dovecot.org/releases/1.2/dovecot-1.2.11.tar.gz http://dovecot.org/releases/1.2/dovecot-1.2.11.tar.gz.sig mbox users really should upgrade, because by sending a message with a huge header you could basically cause a DoS (this problem exists only with v1.2.x, not with v1.0 or v1.1). - mbox: Message header reading was unnecessarily slow. Fetching a huge header could have resulted in Dovecot eating a lot of CPU. Also searching messages was much slower than necessary. - mbox, dbox, cydir: Mail root directory was created with 0770 permissions, instead of 0700. - maildir: Reading uidlist could have ended up in an infinite loop. - IMAP IDLE: v1.2.7+ caused extra load by checking changes every 0.5 seconds after a change had occurred in mailbox

Re: [Dovecot] I stream read - stale NFS file handle (reboot of server)
by Damon Atkins 18 Mar '10

18 Mar '10

In the old days NFS Shared Path had a static handle (ie a number), normal based on some number pulled out of the file system/inode. To fix (well work around) a security issue, for about 10+ years now, when a NFS server reboots, it generates a new random handle for the NFS Share. (sever may generate a new random handle per mount request) The NFS Stale Handle happens when the client is still using the old NFS handle, the only fix is a remount Some NFSv3 server let you fix the handle id for NFS share so it does not change over reboots. (this is how NFS clustering works, sometimes you need to install cluster software if the exportfs/share command does not let you hard code the fsid by hand. The other option is to use NFSv4 which is design to handle reboots by servers.

[Dovecot] Testing EXTERNAL AUTHENTICATION
by Stephen Feyrer 17 Mar '10

17 Mar '10

Hi. I'm trying to test EXTERNAL AUTHENTICATION in Dovecot. To do this I first configured Thunderbird and Opera to use my server, neither of them were successful. As a result I contacted both organisations to enquire if they supported EXTERNAL AUTHENTICATION in their products. Thunderbird responded and said yes. However, on closer inspection my contact at Thunderbird identified that support for EXTERNAL AUTHENTICATION was poor at best and then only in SMTP. From that point on, my contact has been trying to implement support in Thunderbird. I've also try to test using openssl s_client which is detailed below.

Hello, i discovered that when a sieve rule "fileinto drawer;" tries to deliver a mail into a non existent drawer, the drawer gets created. This is neat, but is there also a way to automatically subcribe to the created folder ? Regards, Oliver Eales

[Dovecot] qmail-secretary plugin for dovecot deliver
by Rajkumar S 17 Mar '10

17 Mar '10

Hi, I have been using qmail-ldap for quite some time and now moved to postfix/dovecot. One feature that I miss is that provided by qmail-secretary. qmail-secretary basically is a mail list manager with following features: 1 no limit, just explode to all members 2 members only, as the name says; only members are allowed (based on envelope sender, so not very secure, everybody can fake that) 3 sender confirm, sender has to confirm submission and return address like DJBs qmail-secretary 4 moderated, moderator(s) have to accept every message; there are DN and RFC822 moderators All configuration (name, members, moderated etc...) are taken from LDAP. I had gone through the code and from what I understand for each 4 delivery types it works as follows: 1. Just deliver to all recipients (say, inject it via sendmail). 2. verify if envelope sender is in allowed list and proceed as above. 3. 1. create a random hash 2. save the mail in new/ with hash as filename 3. create a new mail with listname-confirm-hash(a)domain.com and send 4. If that mail comes back, deliver the mail to all recipients. 4. 1. as above but using listname-approve-hash and list-name-reject-hash 2. move the msg to cur/ 3. if appropriate reply comes retrieve the mail from cur/ and send to all recipient. qmail-secretary is invoked by qmail-local and thus this is a nice candidate for a deliver plugin. Before I start coding I just want to check if there is any gotchas that I am missing? I assume all these operations can be performed as a deliver plugin and that deliver plugin is the correct place for such functionality. It goes without saying that I would be contributing this plugin back to dovecot. with regards, raj

Re: [Dovecot] [xmail] XMail + Dovecot
by Sabahattin Gucukoglu 17 Mar '10

17 Mar '10

What, exactly, is the problem? How do you want Dovecot and XMail to work together? I am setting up Dovecot to read from standard Maildirs in user home directories, because I am using a separate delivery agent (TMDA but would work for maildrop, Dovecot's deliver program and others) to deliver mails using mailproc.tab. So, even while XMail runs as root, Dovecot need not and there is no problem getting it to work just like with other MTAs. XMail can't help with delivery to Maildir because it runs as root, and unless you mess about with packet filters to non-root it you'll still end up using for instance XACLs to allow Dovecot to read the mails. For authentication of XMail to Dovecot you would have to write external authentication helpers that use Dovecot's protocol. Or, you can use checkpassword or PAM-POP3 or something else to try getting Dovecot to authenticate against the active XMail list of users. Or you can just do what I do, maintain two databases and keep them in sync. Cheers, Sabahattin

[Dovecot] Design: Asynchronous I/O for single/multi-dbox
by Timo Sirainen 17 Mar '10

17 Mar '10

The long term plan is to get all of Dovecot disk I/O asynchronous. The first step to that direction would be to make dbox/mdbox I/O asynchronous. This might also allow mbox/maildir to become partially asynchronous. http://www.dovecot.org/list/dovecot/2009-December/045481.html already started describing how the lib-storage API could be changed to support high-latency storages. Adding support for all of the paralellism would be nice, but probably not necessary as the first step. Then again, the API changes are necessary, so the parallelism optimizations probably aren't a huge task on top of that. Besides the API changes described in the above link, another change that's necessary is to add mail_get_nonblocking_stream(). The returned stream can return EAGAIN whenever it would need to block. Whenever sending message data to client, this stream would have to be used. It would also be used internally by all of message parsing/searching code. Luckily all of that already supports nonblocking input or can be easily modified to support it. Below are some thoughts how to go forward with this. I originally thought about writing a more specific plan, but I think this is good enough now to start coding. The target Dovecot version is v2.1, not v2.0. Filesystem API ============== The idea is to first abstract out all POSIX filesystem accessing in dbox/mdbox code. Non-blocking I/O works pretty nicely for socket I/O, so I thought I'd use a similar API for disk I/O as well: handle = open(path, mode) - this function can't fail. it's executed asynchronously. - mode=read-only: no writing to file - mode=append: appending to file is allowed handle = create(path, mode, permissions) - this function can't fail. it's executed asynchronously. - mode=fail-if-exists: commit() fails if file already exists - mode=replace-if-exists: commit() replaces file if it already exists - permissions: i'm not entirely sure how this works yet. but it should contain mode and gid in some format set_input_callback(handle, callback, context) set_output_callback(handle, callback, context) - call the callback when more data can be read/written ret = pread(handle, buf, size, offset) - just like pread(), but can fail with EAGAIN if there are no bytes already buffered. so the idea is that the backend implementation would buffer/readahead data, which would be returned by this call. this would require memcpy()ing all data, but it might get too complex/fragile if it was asynchronously written to given buffer. ret = write(handle, buf, size) - append data to given file and return how many bytes were actually added to write buffer. works in a similar way than writing to socket. data can only be appended to files, there is no support for overwriting data. - no writes will be visible to reads until commit() is called ret = commit(handle, [filename]) - commit all previous writes to disk. either returns success/EAGAIN. - if filename is given and a new file is being created, the filename is changed to the given one instead of using the original path's filename. this is needed because e.g. mdbox saving can write many temp files in a single transaction and only at commit stage it locks the index files and knows what the filenames will be. rollback(handle) - rollback all previous writes. close(handle) - if file was created and not committed, the temp file will be deleted - does implicit rollback ret = try_lock(handle) - this isn't an asynchronous operation! it assumes that locking state is kept in memory, so that the operation will be fast. if backend doesn't support locking or it's slow, single-dbox should be used (instead of multi-dbox), because it doesn't need locking. - returns success or "already locked" - only exclusive locking is possible Async IO streams ================ Async input streams are created with FS API handle, so it's possible to start reading from them before the file has even been open()ed. The callers must be aware of this and realize that read() can fail with ENOENT, etc. Async input streams' read() would work exactly as file_istream works for non-blocking sockets: It would return data that is already buffered in memory. If there's nothing, it returns EAGAIN. The FS API's set_input_callback() can be used to set a callback function that is called whenever there's more data available in the buffer. Async output streams also work the same as non-blocking file_ostreams: write() returns the number of bytes added to buffer. When buffer becomes full, it starts returning EAGAIN. The ostream handles flushing internally the same way as file_ostreams does, although instead of using io_add(IO_WRITE) it uses FS API's set_output_callback(). If callers need to know when more data can be written or when all of the data has been written, it can override the ostream's flush_callback, just like with file_ostreams. Async IO for FS API backend =========================== So now that all of the APIs have been designed, all that's needed to do is to write a simple FS API implementation using kernel's async IO API, right? Wrong. There is no usable async IO API in Linux, and probably nowhere else either: * POSIX AIO isn't supported by Linux kernel. And even if it was, it only supports async reads/writes, not async open(). * Linux kernel has its own native AIO implementation! ..But it only works with direct IO, which makes it pretty much useless for almost everyone. There have been many different attempts to get buffered AIO support to Linux, but all of them have failed. So for now the only practical way is to implement it with threads. There are several libraries that could make this easier.. But all of them enable (and require) full thread safety for libc calls. I don't really like that. Dovecot isn't using threads, I shouldn't pay the penalty of using extra locking when it's really not necessary. So I was thinking about doing the async IO in two ways: 1) For Linux/x86/x86-64 (and maybe others) implement a version that creates threads with clone() and uses lockless queues for communicating between the async io worker threads. The threads won't use malloc() or any other unsafe calls, so this should be pretty nice. 2) Fallback version that uses pthreads with mutexes. Is 2) going to be noticeably slower than 1)? Probably not.. In both cases there is also the problem of how many worker threads to create. I've really no idea, kernel would be so much better in deciding that.. I guess that also depends on how many processes Dovecot is configured to run on (and how busy they are at the moment). Maybe it could be just a globally configurable number of threads/process, defaulting to something like 10. dbox changes ============ Most of the dbox code shouldn't be too difficult to change to using the FS API. The one exception is writing messages. Currently the format looks like: <dbox header magic (2 bytes)> <dbox message header, which contains message size><lf> <message> <dbox metadata magic (2 bytes)><lf> <dbox metadata> <lf> The problem is that the message size isn't always known before the message is written. So currently the code just pwrite()s the size afterwards, but this is no longer possible with the new FS API. One possibility would be to buffer the message in memory, but that could waste a lot of memory since messages can be large. So the only good solution is to change the dbox file format to contain the message size after the message. At the same time the dbox format could be cleaned up from old broken ideas as well. The reading code could support the old version format as well, because reading isn't a problem. The new dbox format could look like: <dbox header magic (2 bytes)> <dbox unique separator (random 16 bytes or so)><lf> <message> <dbox metadata magic (2 bytes)> <dbox unique separator, same as above><message size><lf> <dbox metadata, last item being metadata size> <lf> The unique separator exists there primarily for fixing corrupted dbox storage, so it can (quite) reliably recognize where a message ends. Multi-dbox's indexes contain already the message offset + size of (message+metadata), i.e. offset+size = offset of next message. The size is primarily used to figure out if more data can be appended to the file (so it won't grow too large). This size could just be changed to become message's size and the check just changed to assume metadata size would be e.g. 512 bytes. It won't really matter in practise. So then the reading code could get the message's size from the index. Single-dbox doesn't have such index. There are two ways to solve the problem there (both actually would work for multi-dbox too): 1) Metadata block can be found by reading backwards from end of file. For example read the last 512 bytes of the file and find the metadata magic block. Get the message's size from there. 2) Create an istream that simply reads until it reaches dbox metadata magic and unique separator. And to be absolutely sure it reached the correct end of message, it can also check that the rest of the data in the stream contains only a valid metadata block.

by Wilberth Pérez 17 Mar '10

17 Mar '10

some one knows, how to configure quotas with dovecot and mysql databases ? my dovecot was compiled with: CPPFLAGS=-I/opt/mysql/include/mysql LDFLAGS=-L/opt/mysql/lib/mysql ./ configure --with-sql --with-mysql and my dovecot.conf and dovecot-sql.conf have the following configurations: =========== dovecot.conf =========== protocol imap { listen = *:143 mail_plugins = quota imap_quota } protocol pop3 { listen = *:110 mail_plugins = quota } plugin { quota = maildir:storage=30M quota_rule = *:storage=30M quota_warning = storage=95%% /usr/local/bin/quota-warning.sh 95 quota_warning2 = storage=80%% /usr/local/bin/quota-warning.sh 80 } ============ dovecot-sql.conf ============ driver = mysql connect = host=localhost dbname=mail user=mail password=mail user_query = SELECT 1 AS gid, concat('maildir:storage= ', quota_kb) AS quota FROM users WHERE user = 'testuser'; I test my configuration and don't show errors , however, dovecot never show me my quota configuration. I will be omitting something ?

[Dovecot] Dovecot 2.0beta3: Auth master process is now running as default_internal_user
by Thomas Leuxner 16 Mar '10

16 Mar '10

Hi, with 'changeset 10910' the Auth master process is running as 'default_internal_user' now (dovecot). This requires permissions tuning for 'passwd-files' at least, while other plugins would run in a different user context, 'vmail' in my setup. I see that this may be safer, just wondering how to streamline the config: [20:27] root spectre:/var/vmail/conf.d# l drwxr-x--- 4 dovecot vmail 4096 2010-03-14 17:40 leuxner.net [20:27] root spectre:/var/vmail/conf.d# l leuxner.net/ drwx------ 2 vmail vmail 4096 2010-03-14 13:09 acls -r-------- 1 dovecot vmail 125 2010-02-07 13:08 passwd drwx------ 2 vmail vmail 4096 2010-03-14 12:13 sieve [20:27] root spectre:/var/vmail/conf.d# cat leuxner.net/passwd tlx@leuxner.net:{SSHA}xxxx:5000:5000::/var/vmail/leuxner.net/tlx::userdb_quota_rule=*:storage=5G […] Regards Thomas

[Dovecot] ACL problem
by SZÉKELYI Szabolcs 16 Mar '10

16 Mar '10

Hey, I seem to have a problem with ACLs. I'm trying to use them on shared folders those work fine without it. But as soon as I enable the plugin and create the dovecot-acl files, they disappear. I used strace to see if there's a problem with file permissions, but it looks like Dovecot doesn't even attempt to access the dovecot-acl file in the maildir, only the dovecot-acl-list files. However, it does look for dovecot-acl files in users' home directories. Maybe the ACL plugin is enabled only for the private mailboxes, not for the public ones, but I want right the opposite. How can I achieve it? Please find my dovecot config below. Thanks, -- cc # 1.2.4: /etc/dovecot/dovecot.conf # OS: Linux 2.6.26-2-686 i686 Debian 5.0.4 log_timestamp: %Y-%m-%d %H:%M:%S protocols: imaps ssl: required ssl_cert_file: /etc/ssl/certs/imapd.pem ssl_key_file: /etc/ssl/private/imapd.key.pem login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login mail_privileged_group: mail mbox_write_locks: fcntl dotlock mail_plugins: acl namespace: type: private location: mbox:%h:INBOX=/var/mail/%u inbox: yes list: yes subscriptions: yes namespace: type: public separator: / prefix: Logs/ location: maildir:/data/mail/logs:LAYOUT=fs:INDEX=~/.imap- public/Logs:CONTROL=~/.imap-public/Logs list: yes auth default: passdb: driver: pam userdb: driver: passwd plugin: acl: vfile

[Dovecot] Authentication userdb file / configuration help - newbie question...
by Zilon X 16 Mar '10

16 Mar '10

Hi All, I need to configure Dovecot with a XMail server ( www.xmailserver.org ) - this server uses a userdb file with the following format: "domain"[TAB]"account"[TAB]"encrypted-passwd"[TAB]"account-id"[TAB]"account-dir"[TAB]"account-type"[NEWLINE] How can authenticate Dovecot against this userdb file? Was anyone doing that? Maybe, can I authenticate Dovecot using SMTP Auth? Thank you for any help!

[Dovecot] Dovecot 2.0b3: mdbox with incorrect ACL file permissions crashes
by Thomas Leuxner 16 Mar '10

16 Mar '10

Hi, played around with 'mdbox' format some more. Converted my personal mailbox with latest Dovecot and dsync from HG: dsync convert -u login(a)yourdomain.com mdbox:~/mdbox One thing I noticed is, that dsync does not take care of existing 'dovecot-acl' files, which it should migrate/copy from my point of view, but simply skips them. Anyway I copied over the ACLs manually and forgot to set the rights accordingly. So the files were owned by 'root:vmail' instead of 'vmail:vmail' in my setup. Voilà Dovecot crashed, where it should really throw a warning or ignore the owner and work with the group permissions: Mar 2 19:27:52 spectre dovecot: imap(tlx(a)leuxner.net): acl vfile: file /var/vmail/conf.d/leuxner.net/acls/Support/Serverloft not found Mar 2 19:27:52 spectre dovecot: imap(tlx(a)leuxner.net): acl vfile: no access to file /var/vmail/leuxner.net/tlx/mdbox/mailboxes/Support/Serverloft/dbox-Mails/dovecot-acl Mar 2 19:27:52 spectre dovecot: imap(tlx(a)leuxner.net): Panic: file acl-cache.c: line 295 (acl_cache_update_rights): assertion failed: (obj_cache->my_current_rights != &negative_cache_entry) Mar 2 19:27:52 spectre dovecot: imap(tlx(a)leuxner.net): Raw backtrace: /usr/lib/dovecot/libdovecot.so.0 [0x7f4d8595ffb2] -> /usr/lib/dovecot/libdovecot.so.0 [0x7f4d8596001a] -> /usr/lib/dovecot/libdovecot.so.0 (i_error+0) [0x7f4d859603c3] -> /usr/lib/dovecot/modules/lib01_acl_plugin.so [0x7f4d84da690b] -> /usr/lib/dovecot/modules/lib01_acl_plugin.so [0x7f4d84da4249] -> /usr/lib/dovecot/modules/lib01_acl_plugin.so [0 x7f4d84da4572] -> /usr/lib/dovecot/modules/lib01_acl_plugin.so [0x7f4d84da472e] -> /usr/lib/dovecot/modules/lib01_acl_plugin.so [0x7f4d84da2aba] -> /usr/lib/dovecot/modules/lib01_acl_plugin.so(acl_object_get_m y_rights+0x65) [0x7f4d84da2b85] -> /usr/lib/dovecot/modules/lib01_acl_plugin.so [0x7f4d84da8fd9] -> dovecot/imap [tlx(a)leuxner.net 84.58.106.99 STATUS](client_find_namespace+0x17f) [0x41149f] -> dovecot/imap [t lx(a)leuxner.net 84.58.106.99 STATUS](cmd_status+0xfc) [0x40dc2c] -> dovecot/imap [tlx(a)leuxner.net 84.58.106.99 STATUS] [0x40f9bc] -> dovecot/imap [tlx(a)leuxner.net 84.58.106.99 STATUS] [0x40fa6d] -> dovecot/imap [tlx(a)leuxner.net 84.58.106.99 STATUS](client_handle_input+0x45) [0x40fbe5] -> dovecot/imap [tlx(a)leuxner.net 84.58.106.99 STATUS](client_input+0x62) [0x410622] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handl er_run+0xcb) [0x7f4d8596abab] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_run+0x18) [0x7f4d85969d28] -> /usr/lib/dovecot/libdovecot.so.0(master_service_run+0x13) [0x7f4d85959eb3] -> dovecot/imap [tlx(a)leuxner.n et 84.58.106.99 STATUS](main+0x191) [0x418661] -> /lib/libc.so.6(__libc_start_main+0xe6) [0x7f4d851e71a6] -> dovecot/imap [tlx(a)leuxner.net 84.58.106.99 STATUS] [0x4084e9] Mar 2 19:27:52 spectre dovecot: master: service(imap): child 30281 killed with signal 6 (core dumps disabled) Regards Thomas

[Dovecot] Shared folders
by Неворотин Вадим 16 Mar '10

16 Mar '10

I need to create a shared folder (mailbox for group mailing list) with access of several accounts to it. But all peoples with access to this mailbox should be able to work with this folder absolutely in the same way, as with local mailbox. Each user should be able to delete emails and mark it as readed. But this changes must be only for one user, not for others. For example user1 and user2 have access to folder Trades. There is a new incoming mail. User1 read it and delete. But in user2's client this mail must be not readed and not deleted. So there should be only one copy of a email (in group mailbox), but state (unreaded|readed|deleted) of this email shoud be different for each user. Can I do this with dovecot? Yes, I know that I can send a copy of group letter to each user's mailbox, but unfortunately I has a lot of groups and very big letters, so I can't duplicate each letter to many mailboxes. The purpose is to story only one instance of each letter, but to allow users to work with it like with their own letters. Now I use Maildir++ mailboxes.

[Dovecot] Quota plugin and SQL
by David 16 Mar '10

16 Mar '10

I have read through http://wiki.dovecot.org/Quota/Dict, which suggests a database schema for using quota. For 1.2, this includes a username, bytes and messages. Is there any way to modify the queries used to split out username into localpart and domain? This would enable me to put the current quota information in my main mailbox table and display it to users in my admin interface. Or possibly it should be in a separate table for a reason, and I should be look there for the values? Thanks, David

[Dovecot] extraneous mail folder created
by John Moorhouse 16 Mar '10

16 Mar '10

I'm trying to set up dovecot on a Fedora box for about 5 users, I have a raid 5 array that is used for home folders etc mounted on /home, and I've created a directory /home/mail, which I have used a sym link to map /var/mail to. I've created folders for each of the users with relevant permissions and edited the dovecote config with:- namespace private { separator = / prefix = "#dbox/" location = dbox:~/mail:INBOX=/var/mail/%u inbox = yes hidden = yes list = no # for v1.1+ } namespace private { separator = / prefix = location = dbox:/var/mail/%u/mail } This all seems to work with the exception that when a imap client attaches to dovecot an empty folder called 'mail' is created in the users home directory. so for client jenni, whist all her emails etc are stored in /home/mail/jenni/ for INBOX and /home/mail/jenni/mail/ for folders etc, an empty folder is created as /home/jenni/mail/ Any help appreciated John

[Dovecot] IMAP proxy configuration
by Leonardo Rodrigues 16 Mar '10

16 Mar '10

i know dovecot can act as IMAP and POP3 proxy ..... but i'm having a hard time configuring it. Actually i'm using a simple dovecot configuration with virtual users stored on MySQL. My dovecot-sql.conf is pretty simple: [root@correio dovecot]# cat dovecot-sql.conf driver = mysql connect = host=localhost dbname=DATABASE user=USERNAME password=PASSWORD default_pass_scheme = PLAIN # Get the mailbox user_query = select '/var/spool/mail/%u' as home, 'maildir:/var/spool/mail/%u' as mail, 8 as uid, 12 as gid, concat('*:storage=', quota) as quota_rule, 'Trash:storage=100M' as quota_rule2 from emails where endereco = '%u' and ativa = '1' # Get the password password_query = select endereco as user, password, '/var/spool/mail/%u' as userdb_home, 'maildir:/var/spool/mail/%u' as userdb_mail, 8 as userdb_uid, 12 as userdb_gid, concat('*:storage=', quota) as userdb_quota_rule, 'Trash:storage=100M' as userdb_quota_rule2 from emails where endereco = '%u' and ativa = '1' [root@correio dovecot]# i've read several docs about configuring proxy on dovecot but all of them says about proxying specific users .... i'm interested on proxying some domains. I couldnt find a way to configure that nor some howto similar to that. could anyone point me some documentation on configuring dovecot as IMAP/POP3 proxy for a full domain and not specific users ? Ideally i would have a list of domains that should be proxied to somewhere else and all the other domains would be threated locally.

[Dovecot] dovecot-2.0.beta3 does not create dovecot/login directory
by Jürgen Bereuter 16 Mar '10

16 Mar '10

Hello, i build the beta3 of dovecot 2.0 on Opensolaris (SunOS sol 5.11 snv_134 i86pc i386), restarted and dovecot logs the following error. I created the directory path /var/run/dovecot/login and voila, imap is starting up without any problems. But as soon as i reboot the PC (it is only a pseudo private server), the new directory gets deleted (as expected and planed, as fa as i know), but not to be (re)created. Not a big problem, but i think it is worth to mention it. Perhaps i am wrong and messed something completely up, in that case i would be glad to receive a clue.
