[Dovecot] auth server refusing connections intermittently
by Steven F Siirila 28 Mar '07

28 Mar '07

Running Dovecot 1.0-rc27 on Solaris 10.. We have been noticing intermittent messages of this sort and wondered if this indicates whether we need to add more dovecot-auth worker processes: Mar 28 03:15:41 myhost dovecot: pop3-login: Can't connect to auth server at default: Connection refused Mar 28 08:10:20 myhost dovecot: imap-login: Can't connect to auth server at default: Connection refused Mar 28 09:08:13 myhost dovecot: imap-login: Can't connect to auth server at default: Connection refused Mar 28 10:23:38 myhost dovecot: imap-login: Can't connect to auth server at default: Connection refused Mar 28 10:35:37 myhost dovecot: imap-login: Can't connect to auth server at default: Connection refused Mar 28 10:50:59 myhost dovecot: imap-login: Can't connect to auth server at default: Connection refused Mar 28 12:00:44 myhost dovecot: pop3-login: Can't connect to auth server at default: Connection refused Mar 28 12:07:31 myhost dovecot: imap-login: Can't connect to auth server at default: Connection refused Mar 28 14:44:57 myhost dovecot: imap-login: Can't connect to auth server at default: Connection refused However, this system has over 7,000 users and 1,500 simultaneous IMAP and POP3 connections, and we only see one dovecot-auth process running. By contrast, another server has over 11,000 users and 3,000 simultaneous IMAP and POP3 connections (but is currently running rc24), and we only have seen 3 of the above error messages there -- and there is only one dovecot-auth process there as well. Does this sound right? Also, how many times are these connections retried (and at what sleep interval, if any) before it gives up? -- Steven F.

[Dovecot] Removing users maildir DOVECOT+LDAP
by Venilton Junior 28 Mar '07

28 Mar '07

Hi all, Does anyone have an idea how can I remove(delete) my virtual mail users' maildir? I have Dovecot + LDAP and I would like to do something like this: When I remove an user entry in my ldap server, it should remove my user directory information. Does anyone has this implemented? Or have an idea? I can remove users entry in my ldap server remotely, is there some way in dovecot? I'm asking this, cause I'm very familiar with Cyrus and I can do this with it.

[Dovecot] Deliverm, vpopmail, and valias
by John Peacock 28 Mar '07

28 Mar '07

I'm in the final stages of testing my e-mail server to come and I seem to have hit a roadblock. One option of current vpopmail is to store all aliases in a valias table, that looks like this: +-------------+----------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +-------------+----------+------+-----+---------+-------+ | alias | char(32) | NO | MUL | | | | domain | char(64) | NO | | | | | valias_line | text | NO | | | | +-------------+----------+------+-----+---------+-------+ where valias_line could be either an e-mail address (preceded by an ampersand) or a command (piped to vacation for example). I have already accepted a message for an aliased address, but the MTA isn't going to be rewriting the envelope address, so how can I get dovecot's deliver to dereference the alias and deliver to the correct Inbox? Because of the number of other hops[1] that the message is going through, I don't want to rewrite the destination address unless I really have to, but if that is the only option, that is what I'll have to do. Thoughts? John 1) inbound e-mail hits a qpsmtpd instance which validates e-mails using several different filtering techniques. Next the mail gets fed to a dspam appliance running two Postfix queues (one before dspam and one after). Mail that isn't quarantine by dspam gets sent to the delivery server (currently running qmail) and delivered to the final destination (modulo sieve rules under deliver). The only place I could conceivably rewrite the address would be the second Postfix queue. -- John Peacock Director of Information Research and Technology Rowman & Littlefield Publishing Group 4501 Forbes Boulevard Suite H Lanham, MD 20706 301-459-3366 x.5010 fax 301-429-5748

[Dovecot] ignoring some subfolders [potential wishlist]
by Arkadiusz Miskiewicz 28 Mar '07

28 Mar '07

Hello I'm looking at migration path from my current setup (tpop3d/courier-imap) and I seem to miss one feature - ability to ignore some subfolders for pop3. tpop3d allows me to say: maildir-ignore-folders: Spam Trash trash Sent sent-mail POP3-Invisible (would be stupid to fetch own sent-mail via pop3 again 8-) In recent tpop3d cvs version I can also use regexps like maildir-ignore-folders: ^IMAP-Only.*$. Is it possible to ignore some subfolders in dovecot per protocol (like for pop3 only and not imap) ? If not then please consider this as wishlist, maybe in form of location negation like: mail_location = \ maildir:/var/mail/%Lu:!maildir:/var/mail/%Lu/.Something (which doesn't look sane) or with separate config directive like in tpop3d -- Arkadiusz Miśkiewicz PLD/Linux Team arekm / maven.pl http://ftp.pld-linux.org/

[Dovecot] problem with POP3 mail location when using namespaces
by Lutz Preßler 28 Mar '07

28 Mar '07

Hello, I have a problem (at least with 1.0rc28 and 1.0rc27) when using the following namespace definitions: namespace private { separator = "/" inbox = yes location = mbox:~/Mail:INBOX=/var/spool/mail/%u } namespace public { separator = / prefix = 0-LISTS/ location = mbox:/var/mail/lists:INDEX=~/.sharedMail/lists/index } namespace private { separator = "/" prefix = "0-MAILDIR-FOLDERS/" location = maildir:~/Maildir } IMAP access is working as expected, but when connecting with POP3(s), the (mostly empty in our case) ~/Maildir is used as mail location when it has been created (including index files) by IMAP access. If ~/Maildir does not exist/has been deleted again, POP3 uses /var/spool/mail/%u. This is independent of the private namespace section order and also an explicit "inbox = no" in 0-MAILDIR-FOLDERS namespace. Any idea if this is an configuration issue I don't understand yet or a bug?

[Dovecot] proxy host specified as fqdn in userdb
by Apostolos Papayanakis 28 Mar '07

28 Mar '07

Abstract from http://wiki.dovecot.org/PasswordDatabase/ExtraFields/Proxy > > host=s: The destination server's *IP address*. This field is required. > Note that currently it's required to use an IP address since no DNS > resolving is done. > Hello Timo, Here goes one more item for the v2.0 wishlist: Will it become possible to do dovecot imap proxying based on a "host" userdb attribute that is an FQDN (instead of a numeric IP as it is now)? It would simplify things for large smtp clusters that already do LDAP mail routing, based on per user "mailHost" attribute containg mail server FQDNs (according to "IETF Internet Draft LDAP Schema for Intranet Mail Routing", http://www.sendmail.org/m4/laser.txt) It is kinda redundunt to keep an extra LDAP attribute for "host" that contains essentially the same information as "mailHost" attribute, but in numeric form. I know the proposed change is not that important for many people, so don't really bother unless it is trivial to implement. apap

[Dovecot] rc2x seems to break Pegasus Mail
by Rick Romero 28 Mar '07

28 Mar '07

Hi guys, I upgraded from rc7 to rc24 a couple weeks ago, and noticed today that Pegasus Mail's IMAP no longer connects. So I put rc27 in, and it worked, but only for a little while...

[Dovecot] rc29 and documentation changes
by Timo Sirainen 28 Mar '07

28 Mar '07

http://dovecot.org/nightly/dovecot-latest.tar.gz Any comments about the doc/wiki/ contents? doc/documentation.txt? dovecot-example.conf's doc/wiki/ pointers? ./autogen.sh now updates the wiki from http://www.dovecot.org/tmp/wiki-export.tar.gz (updated each night) if doc/wiki/Authentication.txt doesn't exist. I guess I'll release rc29 tomorrow. The current changes are: + Added auth_gssapi_hostname setting. - IMAP: LIST "" "" didn't return anything if there didn't exist a namespace with empty prefix. This broke some clients. - If Dovecot is tried to be started when it's already running, don't delete existing auth sockets and break the running Dovecot - If deliver failed too early it still returned exit code 89 instead of EX_TEMPFAIL. - deliver: INBOX fallbacking with -n parameter wasn't working. - passdb passwd and shadow couldn't be used as master or deny databases - IDLE: inotify didn't notice changes in mbox file - If index file directory couldn't be created, disable indexes instead of failing to open the mailbox. - Several other minor fixes

[Dovecot] MANAGESIEVE patch v3 for dovecot 1.0.rc28
by Stephan Bosch 28 Mar '07

28 Mar '07

Hello dovecot users, I have updated the MANAGESIEVE patch to apply and compile against dovecot 1.0.rc28. Not much has changed with respect to the functionality of the previous version however: ChangeLog vs v2 - Updated source to compile with dovecot 1.0.rc28, tested with rc27 (debian package) - Daemon now uses the same location for .dovecot.sieve as dovecot-lda This is typically ~/.dovecot.sieve. - If .dovecot.sieve is a regular file, it is now moved into the script storage as dovecot.orig.sieve, preventing deletion of (important) active scripts upon managesieve installation. Otherwise, it would simply be replaced by a symlink to the new active script. - Changed error handling to yield a BYE message when the managesieve daemon exits unexpectedly (upon login) before any commands are entered. Horde-ingo would wait indefinitely for a response. This patch still includes (yet another) instance of the CMU Sieve source, as explained in my previous mail (http://dovecot.org/list/dovecot/2006-July/015016.html) It can be downloaded at: http://sinas.rename-it.nl/~sirius/dovecot-1.0.rc28-MANAGESIEVE-v3.diff.gz Have fun testing the patch. Notify me when there are problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl IRC: Freenode, #dovecot, S[r]us

[Dovecot] gssapi auth issue...
by Dan Price 28 Mar '07

28 Mar '07

Hi all-- been away from the list for a few weeks so forgive me if this problem has been reported-- with the help of some of our Kerberos engineers, we tracked down why we can't authenticate our Solaris kerberos clients to Dovecot. Here's the deal: Our IT organization issued us kerberos tickets of the form imap(a)foobar.sfbay.sun.com Which I presume is their standard-- and probably not negotiable. However, the hostname of the machine is: "foobar", not foobar.sfbay.sun.com (as reported by gethostname(3c)). So when dovecot does this: mech-gssapi.c: principal_name = t_str_new(128); str_append(principal_name, service_name); str_append_c(principal_name, '@'); ---> str_append(principal_name, my_hostname); We wind up asking kerberos to look for a ticket for imap@foobar, instead of imap(a)foobar.sfbay.sun.com. Obviously we can patch the source, but I was wondering if we could have a gssapi_hostname setting in the config file? Or perhaps we could have a knob letting us globally override my_hostname? Although I don't know what side effects that could have. We have some new cores I also need to report-- I'll get on that. Thanks in advance, -dp -- Daniel Price - Solaris Kernel Engineering - dp(a)eng.sun.com - blogs.sun.com/dp

[Dovecot] Custom Mail Directory for some users
by Patrick Kranz 27 Mar '07

27 Mar '07

Hi list, I'm new on this mailing list and I'm kind of stucked at the moment. I managed to get Postfix and Dovecot working together with Amavis, OpenLDAP und SASL on Ubuntu Linux Release "Dapper Drake". The Dovecot version shipped with Dapper is 1.0-beta3 (at least, that's what the package database tells me), I also tried this with a Debian Backport of version 1.0-rc15. And here is my problem: A customer of mine needs usernames different from the mail address for his third party software to work. In other words, I need the ability to login with the username foo to get access to the mailbox bar(a)example.com. So I tried to override the mail_location property for this user with a separate mailDirectory attribute in my LDAP tree. Speaking in dovecot.conf words: mail_location = maildir:/var/spool/dovecot/mail/%d/%n auth default { machanisms = plain passdb ldap { args = /etc/dovecot/dovecot-ldap.com } userdb ldap { args = /etc/dovecot/dovecot-ldap.com } userdb static { args = uid=vmail gid=vmail user = dovecot } and dovecot-ldap.conf: hosts = localhost dn = cn=admin,dc=ekits,dc=de dnpass = secret auth_bind = yes ldap_version = 3 base = ou=mailsystem,dc=ekits,dc=de scope = subtree user_attrs = mailDirectory=mail user_filter = (&(objectClass=ekitsMailAccount)(uid=%u)) pass_attrs = uid=user,userPassword=password pass_filter = (&(objectClass=ekitsMailAccount)(uid=%u)) user_global_uid = vmail user_global_gid = vmail a typical ldap entry looks something like this: dn: cn=Patrick Kranz,o=EK IT-Solutions,ou=mailsystem,dc=ekits,dc=de ekitsMailDestination: patrick(a)ekits.de objectClass: ekitsMailAccount objectClass: top cn: Patrick Kranz structuralObjectClass: ekitsMailAccount entryUUID: b4ebb9e8-6d8d-102b-9dc9-9edb870845a4 creatorsName: cn=admin,dc=ekits,dc=de createTimestamp: 20070323132526Z userPassword:: YVBhc3M= mailDirectory: maildir:/var/spool/dovecot/mail/ekits.de/blubb uid: patrick As far as I can interpret the log of slapd, dovecot doesn't even ask for the attribute "mailDirectory". I also tried this with userdb prefetch. With this it did actually ask for the attribute but it still had no effect. With this configuration dovecot creates the directory /var/spool/spool/dovecot/mail/patrick if I login with the uid patrick but I wanted access to /var/spool/dovecot/mail/ekits.de/blubb If anybody has any clue what I did wrong or if I have a conceptional misunderstanding, I would appreciate every help. Thanks in advance. Greetings, Patrick

[Dovecot] Sync of read message status between squirrelmail and outlook express
by Mohd Ikhwan Abdullah 27 Mar '07

27 Mar '07

Hi, We have a Linux email server running CentOS 4.4. I have a scenario here. The users here use a mixture of outlook express and squirrel mail as their email client. The users download their mail into outlook express via pop3 but the have configured outlook express to leave a copy on the server for 7 days. 1. After downloading the mail into outlook express the users would read the mail and the mail would be set as 'READ' in outlook express. 2. Is there a way to configure dovecot so that the 'READ' status in outlook express is reflected on the message still stored on the server as well. Cause when they access via squirrel mail the message is still mark as 'UNREAD'. Any suggestions is very much appreciated. Thanks in advance.

[Dovecot] LDA bouncing mails after upgrade

Hello, on my system, I have a copy of /usr/libexec/dovecot/deliver located in /usr/libexec/dovecot/postfix-deliver/deliver (only accessible to postfix and with SUID root permissions). If I happen to forget to update this copy after an upgrade of dovecot, the deliver LDA bounces mails: | Mar 22 20:29:20 host.example.org deliver(user(a)example.org): Module is for different version 1.0.rc27: /usr/lib/dovecot/lda/lib10_quota_plugin.so | Mar 22 20:29:20 host.example.org postfix/pipe[17344]: <ID>: to=<user(a)example.org>, relay=dovecot, delay=1.9, delays=1.5/0/0/0.35, dsn=5.3.0, status=bounced (Command died with status 89: "/usr/libexec/dovecot/postfix-deliver/deliver") Should I just set version_ignore=yes and remember myself to upgrade it, or could deliver return a code signaling "temporary failure", or should I rather make postfix interpret 89 as temporary failure?

[Dovecot] netapp/maildir/dovecot performance
by bofh list 26 Mar '07

26 Mar '07

We are seeing some poor performance recently that is focused around users with large mailboxes (100,000 message /INBOX, 80,000 message subfolders, etc). The performance problem manifests as very high system% utilization - basically iowait for NFS. There are two imap servers with plenty of horsepower/memory/etc. They are connected to a 3050c cluster via gig-e. Here are the mount options: rw,tcp,nfsvers=3,rsize=8192,wsize=8192,nosuid,nodev,soft,intr,noac,actimeo=0 I need to get this system% utilization brought down because it is starting to slowdown imap performance for other users (it goes up to 95% on a regular basis, with users that have folders with many messages). My thought is to try removing the noac option and bump up the actimeo value from 0 to 30. Unfortunately I don't have access to use a SLB to direct traffic to individual servers. My understanding is that the worst that can happen is index corruption (which will result in rebuilding them when it happens). Any thoughts? I'm running RC24.

[Dovecot] Unwanted INBOX. prefix issues
by Kevin Bowling 26 Mar '07

26 Mar '07

I have a strange problem. I installed Dovecot and had my trash folder and such in the root of my maildir, and everything was working great. I then installed SquirrelMail which created folders in with the INBOX. prefix. I manually removed these from the maildir, but the INBOX.Trash is still shown in the folder listing of Thunderbird. This leads to some strange behavior, such as the delete button not working. Is there a way I can reset the folder list, and take the INBOX.* items out? Any help would be appreciated. Regards, Kevin

[Dovecot] Rpm builders: Dovecot spec file
by Egbert Jan 26 Mar '07

26 Mar '07

Maybe best asked to Axel... I'm re-building my server from scratch (the old one was MDK 10.1 -> Mandriva 2006.0 with Postfix/Courier) and I want to install the latest versions postfix/mysql/postfixadmin/dovecot/squirrelmail. I've been building Dovecot (and postfix) from tarballs/srpm in the past so I know more or less how it all fits together. But I wonder if 'old' patches still need to be included/applied in the building of the latest rc's. I still see references to those patches in the spec file. Unfortunately the latest 'official' rpm for Mandriva (I'm running 2007.0) is rc7 and I never succeeded getting in contact with the Mandriva maintainer to ask the same question. In the Axel's AT rpm I still see some patches included but others than in the Mandriva rc7 spec file. Are those patches not already applied to the latest sources by Timo? Tnx Egbert Jan NL

Hm, so my mailing list archive is up, but when I add nopassword to the list of settings in my passdb passwd-file I get: file auth-request.c: line 924 (auth_request_set_field): assertion failed: (request->passdb_password == NULL) Raw backtrace: dovecot-auth [0x806be11] -> dovecot-auth [0x806bd8c] -> dovecot-auth(auth_request_set_field+0x277) [0x80547d7] -> dovecot-auth [0x8060418] -> dovecot-auth [0x8060509] -> dovecot-auth(auth_request_verify_plain+0xb3) [0x80559b3] -> dovecot-auth [0x8055ac2] -> dovecot-auth(auth_request_verify_plain_callback+0x30) [0x8055b50] -> dovecot-auth [0x8060dbe] -> dovecot-auth(io_loop_handler_run+0x152) [0x806f1c2] -> dovecot-auth(io_loop_run+0x28) [0x806e508] -> dovecot-auth(main+0x2fb) [0x805aaab] -> /lib/tls/i686/cmov/libc.so.6(__libc_start_main+0xc8) [0xb7a3fea8] -> dovecot-auth [0x8050ff1] This is with rc27.

[Dovecot] Bug tracking system
by Timo Sirainen 26 Mar '07

26 Mar '07

There are three reasons why I haven't really bothered setting up a bug tracking system for Dovecot: 1) They're all kind of annoying to use. 2) They all require a lot of stuff like PHP, SQL server, etc. which I don't really want to put into dovecot.org. 3) Probably most importantly: If people start reporing bugs in there, I'm pretty much the only person who will ever read them and reply to them. Currently when people report bugs in here, it's quite useful to have other people read them too. They may already know the bug and say they've reported it, they may have an idea what's causing it, they may know a workaround, etc. All in all, moving things to BTS would most likely cause my life to be harder and it might be more difficult to get some bugs fixed. A couple of days ago I started thinking about this and then I figured out a way to solve all of this nicely with a new and great Dovecot based bug tracking system. :) Just so I won't forget it, here's the plan: Dovecot BTS ----------- The preferred way to report bugs is to send them to dovecot-bugs(a)dovecot.org. The only thing it does is prefix the subject line with [BUG #nnn] and forward it to dovecot(a)dovecot.org. Now everyone can reply to it just as it was a normal mailing list mail. As long the subject contains the "[BUG #nnn]" prefix, it's part of the bug. Existing mailing list threads can also be turned into bugs by replying to the thread's root message with To: dovecot-bugs(a)dovecot.org. This again causes the new reply to contain [BUG #nnn] prefix. Then comes the web part. There's no SQL database or anything, everything is stored in a mailbox in the IMAP server. The mailbox contains the whole dovecot(a)dovecot.org archive. Bug metadata such as priority, status, etc. is stored using IMAP ANNOTATE extension, which allows setting key=value pairs to messages. Unfortunately Dovecot doesn't yet support that extension. Bugs' root messages contain the annotations for the whole bug thread. So to get a list of all bugs, the BTS issues an IMAP SEARCH ANNOTATE command to list all messages with some specific "bug=yes" type of annotation. For those messages then it can fetch the subject and whatever else metadata it wants. Newly created bugs don't have annotations though. To fix that, the BTS also uses ANNOTATEMORE (or is it METADATA nowadays?) extension to keep "last seen message in BTS" state in the mailbox's annotations. It then issues a SEARCH SUBJECT "[bug #" command for the new messages and does THREAD command for them to see if they're the bug root, or if they were replies to another message which should be treated as the bug root. When viewing a bug, the bug metadata comes from the annotations. Annotation history could also be kept, possibly as messages in another history mailbox. The messages for a bug can be viewed by issuing a THREAD (REFERENCES) command and showing all the mails that exist under the bug root. So, any volunteers to implement the web part, if I implement the ANNOTATE extension? :) It would actually even be possible to implement multiple frontends. All I need to do is give you access (read-only, or read-write for some) to the bug tracking mailbox, and you can use whatever frontend you wish, even a non-web one!

[Dovecot] Dovecot LDA issues
by Steven F Siirila 26 Mar '07

26 Mar '07

We've seen two issues come up with Dovecot LDA, both of which have caused us problems: 1) If the user's home directory does not exist, or is not owned by them, deliver fails and causes the mail message to bounce back to the originator. In our environment this happens when our user is moved to another server (where we move their files, but for up to 24 hours afterwards, continue to re-mail their /var/mail INBOX). This no longer works because the user has no home directory, causing deliver to fail with "Permission denied" when attempting to create their home directory for the purposes of creating INBOX index files. 2) If the user is over quota (in their home directory), deliver fails with a temporary error, causing requeues until the user is back under quota (which in our environment could be a long time, days). Since we've never had quotas on the user's INBOX (in /var/mail), this is a problem for us. I'd propose for both of these cases that deliver issue WARNING messages to its logs, and simply not create index files for the INBOX. If the INBOX index files already exist, and the user is over quota in /home, neither deliver nor any other Dovecot process should attempt to update them, and instead issue WARNING messages. This allows the e-mail to be delivered instead of requeued, or worse yet, rejected. Index files are supposed to make things perform better, not worse, in ALL cases. :) -- Steven F.

[Dovecot] deliver: -m, sieve and -n
by Jim Horner 26 Mar '07

26 Mar '07

Hi, I took a stab at editing the wiki ... the changes disappeared? I guess I was overruled. The wiki (http://wiki.dovecot.org/LDA) states -m <mailbox>: Destination mailbox (default is INBOX). If the mailbox doesn't exist, it's created (unless -n is used). If message couldn't be saved to the mailbox for any reason, it's delivered to INBOX instead. I tried to add a little note that the sieve plugin takes precedence. For example if at the end of the a .dovecot.sieve there is a line like: fileinto "CompanyFolders.general"; then the -m <mailbox> is ignored. I am not sure about the use of 'stop'. -n: If the destination mailbox doesn't exist, don't create it. This affects both -m parameter and fileinfo action in Sieve scripts. The fallback is to deliver mail to INBOX. (typo: fileinto not fileinfo) My testing shows that if the mailbox does not exist then the mail is rejected like so: === Your message was automatically rejected by Dovecot Mail Delivery Agent. The following reason was given: Mailbox doesn't exist: mail-lists.debian === I like the wiki's solution better. Jim

[Dovecot] dovecot authentication & exim in rc27
by Richard P. Welty 26 Mar '07

26 Mar '07

[introduction: new to the list, used dovecot w/exim as MTA in simple ways for 2 years, blah blah blah] i'm trying to get exim to use dovecot auth with a copy of rc27 and am missing something that's probably quite simple. specifically, how does one configure the authenticators in dovecot.conf for rc27? the auth section of the default config file installed in rc27 doesn't entirely look like what i'm seeing in other documentation; instead of auth default { } i'm seeing auth = default followed by lots of standard flags prefixed by auth_, but i don't see how to set up the socket. i have the following; dovecot starts and doesn't complain but it doesn't create the socket either: auth_socket listen { client { path = /var/run/dovecot/auth-client mode = 0660 user = exim group = exim } } any suggestions? thanks, richard

[Dovecot] anonymous mailing list archive configuration?
by Johannes Berg 25 Mar '07

25 Mar '07

Hi, I'd like to run a mailing list archive via IMAP like for this list but my mails are in maildir and not mbox. It's easy to add a new user that has access to the maildir that mails get stored in, and I can simply link that up to that user's inbox. It's also easy to prevent putting mail into that folder. However, one thing I'm not clear on is how to prevent that user from creating new folders. I don't think I can do that with permissions to the ~/Maildir since that user needs to be able to create files there for indizes etc. Is that possible? Should/can I write a plugin that prevents things? johannes

[Dovecot] Design docs in wiki

[Dovecot] 1.0.rc28 / v1.0 plans
by Timo Sirainen 24 Mar '07

24 Mar '07

I'll probably release 1.0.rc28 in a few days. Would be nice to get some testing for it first. http://dovecot.org/nightly/dovecot-latest.tar.gz contains pretty much what it's supposed to be. I've now replied to all the mails I was planning on replying, excluding the few patches that are v1.1 material. If you think I forgot to reply to some mail, please resend it. I think the documentation in Wiki is finally beginning to look pretty good. All the important things are done. The only things in my "would be nice TODO" list are: - Add a new page about index files and their configuration. I'll probably do this before rc28. - PasswordSchemes and Authentication/Mechanisms are pretty heavy reading. Could be made easier to understand. Possibly also create some mechanism-specific pages describing how to configure them in Dovecot and in clients. - Design documents would also be nice, but not very useful for non-programmers and pretty big job to write them I'm planning on adding the Wiki pages to doc/wiki/ in the tarball and changing: - http://wiki.dovecot.org/* links to doc/wiki/*.txt in dovecot-example.conf - doc/variables.txt could be removed and links to it updated to doc/wiki/Variables.txt - doc/auth-protocol.txt is also already in wiki. Maybe create doc/design/ and put the AuthProtocol.txt there and other design wiki pages there as well. As for v1.0, it looks like there aren't many bug reports anymore about rc27. If there are as few for rc28, I'll release v1.0 in about a month. So unless something special happens, I'll fix only the simplest bugs after rc28 and leave the rest to v1.1/v1.0.1. Hmm. Looks like 13.4. is Friday. Perhaps that's a good day for a release. :) Looks like I ended up adding a few more new features to rc28: * deliver + userdb static: Verify the user's existence from passdb, unless allow_all_users=yes * dovecot --exec-mail: Log to configured log files instead of stderr + When copying/syncing a lot of mails, send "* OK Hang in there" replies to client every 15 seconds so it doesn't just timeout the connection. + Added idxview and logview utilities to examine Dovecot's index files + passdb passwd and shadow support blocking=yes setting now also + mbox: If mbox file changes unexpectedly while we're writing to it, log an error. + deliver: Ignore -m "" parameter to make calling it easier. + deliver: Added new -n parameter to disable autocreating mailboxes. It affects both -m parameter and Sieve plugin's fileinto action - auth cache: If unknown user was found from cache, we didn't properly return "unknown user" status, which could have caused problems in deliver. - Index view syncing fixes - rc27 didn't compile with some non-GCC compilers - vpopmail support didn't compile in rc27 - NFS check with chrooting broke home direcotry for the first login - deliver: If user lookup returned "unknown user", it logged "BUG: Unexpected input" - convert plugin didn't convert INBOX

[Dovecot] Dovecot LDA Logging
by Jonathan Stewart 23 Mar '07

23 Mar '07

I have Dovecot LDA logging fine right now but I really don't like having my log files world writable because I have users with shell access. Is there a way to have Dovecot LDA log to syslog or would it be possible to write a mini-daemon that could log to syslog on behalf of Deliver or something else altogether? Jonathan

[Dovecot] multiple instances of dovecot on one machine
by Marshal Newrock 23 Mar '07

23 Mar '07

I was trying to run two instances of dovecot on the same machine, each listening on a single IP. The problem I ran into was that each time one was started or restarted, the other stopped responding. I saw the following in the logs: Mar 23 00:02:27 sentinel dovecot: Dovecot v1.0.rc27 starting up Mar 23 00:02:27 sentinel dovecot: Socket already exists: /var/run/dovecot/dict-server After I saw that, I commented out the dict section and quota from the plugins. The second line disappeared, but I could still only get one dovecot listening at a time. In the end, I went back to a single dovecot listening on all IP's, and found another way to do what I was trying to do, so all is still working for me. I'm guessing I'm the first person to try to run two dovecots on one machine. Actually, I should clarify: there was also a third, listening to none on localhost, but there only for the lda process. The auth socket was set to /var/run/dovecot/auth-master. And this also was not accepting connections while the others were running. -- Marshal Newrock Ideal Solution, LLC - http://www.idealso.com

[Dovecot] Possible bug with removing e-mail when user over fs quota
by Qweb - Yavuz Aydin 23 Mar '07

23 Mar '07

Dear list, I don't know if this is by design or possibly a bug, but there is a difference when removing e-mail when a user is over filesystem quota when indexing is on or off. All is working fine on our servers when indexing is on, users can remove then purge e-mail when over quota, but when we turn off indexing (by setting INDEX=MEMORY) it doesn't work. Users can remove, but not purge. And after a reload of the page the e-mail is there again. We are using Dovecot 1.0.rc15 on Debian Sarge (through backports.org) with mboxes. We have set up the configuration of dovecot regarding quota's according to http://wiki.dovecot.org/Quota/FS Unfortunately I don't have time to try this on the latest version, but is there anyone out there willing to try? -- Best regards, Yavuz Aydin Qweb Internet Services

Hello all, Recently I have received a few complaints from users that their quota was being reported wrong. This seems to have started when I switched to quota=maildir and ignore=Trash (did both at the same time). The main reported problem is that maildirsize is not correctly updated when they delete messages. My personal hypothesis is something like this: - User moves to Trash - Trash is ignored so it is not marked on the maildirsize (?) - User purges trash - Trash is still ignored so it is still not marked (?) Resulting in a buildup of errors in the maildirsize file. Would it be a good idea to mark the maildirsize file when a file is moved to an ignored folder? That could though potentially lead to people just moving to trash instead of deleting. Thank you guys and keep up the good work! -- Alan Mosca Systems Administrator Aluminati Network Group

[Dovecot] Timeout while logging in
by Kevin Richter 23 Mar '07

Hi, sometimes there is a timeout, while logging in. Dovecot-rc24 Dovecot uses PAM, PAM uses a LDAP server. Solaris 10 The log, if everything is ok: auth(default): client in: AUTH 1 PLAIN service=POP3 secured lip=x.x.x.x rip=x.x.x.x resp= auth(default): client out: CONT 1 auth(default): client in: CONT<hidden> auth(default): client out: OK 1 user=ssal0041 auth(default): master in: REQUEST 453 4779 1 auth(default): master out: USER 453 ssal0041 system_user=ssal0041 uid=3092 gid=1100 home=/home/ss pop3-login: Login: user=<ssal0041>, method=PLAIN, rip=x.x.x.x, lip=x.x.x.x, TLS POP3(ssal0041): Effective uid=3092, gid=1100 POP3(ssal0041): mbox: data=/home/ssal0041/mail/:INBOX=/var/mail/ssal0041 POP3(ssal0041): mbox: root=/home/ssal0041/mail, index=/home/ssal0041/mail, inbox=/var/mail/ssal0041 POP3(ssal0041): Disconnected: Logged out top=0/0, retr=0/0, del=0/0, size=0 The log, if a timeout occures: auth(default): client in: AUTH 1 PLAIN service=POP3 secured lip=x.x.x.x rip=x.x.x.x resp= auth(default): client out: CONT 1 auth(default): client in: CONT<hidden> auth(default): client out: OK 1 user=ssal0041 auth(default): master in: REQUEST 454 4770 1 auth(default): master out: USER 454 ssal0041 system_user=ssal0041 uid=3092 gid=1100 home=/home/ss pop3-login: Login: user=<ssal0041>, method=PLAIN, rip=x.x.x.x, lip=x.x.x.x, TLS The rest is missing.

Re: [Dovecot] deliver to subfolder with dovecot's LDA

So this might not work when there is no "+folder". Timo: Should -m treat empty string as if -m was not passed at all? Bill

[Dovecot] I wrote a managesieve server for Dovecot
by Neale Pickett 22 Mar '07

22 Mar '07

I have written a managesieve server from scratch in Python. I did just enough work to get it working with avelsieve (the squirrelmail plugin), smartsieve, and KDE's sieve kioplugin. It supports the entire Internet draft. Since I didn't have a working sieve server to compare against, I'm not sure if it's 100% compatible with timsieved. Client applications seem to work okay anyway. I wrote it in such a way as to decouple how authentication is carried out and how sieve scripts are actually stored, so you could for instance modify this to work with SASL and Exim. Currently it only has code for PAM and Dovecot's LDA, because I run Postfix :). TLS support is in the code but disabled because I had problems writing a unit test for it. All my connections are from localhost anyway. http://woozle.org/~neale/repos/pysieved if anyone is interested. I haven't looked closely at Stephan Bosch's managesieve server in C but I do want to acknowledge that he has written a C managesieve server that currently exists as a patch to the Dovecot source code. People looking for a managesieve implementation in C are encouraged to try his patch out: http://sinas.rename-it.nl/~sirius/ Neale

[Dovecot] tilde in mbox:, when used in non-system user db
by Michal Soltys 22 Mar '07

Originally I've thought that this is related to INBOX field, but it turned out it happens only when you specify mbox. Consider following passwd-file: testms::10000:10000:imap,,,:/home/vmail/ppgk.com.pl/testms/./::userdb_mail=mbox:~/Mail:INBOX=/home/vmail/ppgk.com.pl/%u/inbox or following line from userdb static: args = uid=10000 gid=10000 home=/home/vmail/ppgk.com.pl/%u/./ mail=mbox:~/Mail:INBOX=/home/vmail/ppgk.com.pl/%u/inbox In both cases, in user's directory, there will be an empty ~/Mail directory created, in addition to Mail and inbox. No idea about how sql or ldap would behave here, but global mail_location from dovecot.conf doesn't suffer from this issue (~ was expanded properly in ktrace dump). Chroot specification (/./) doesn't matter here. If I change mbox:~/Mail:INBOX=..... to mbox:/home/vmail/ppgk.com.pl/%u/Mail:INBOX=~/inbox then everything will be fine - no extra '~' dir. Thus my assumption it's not INBOX field related. Looking at ktrace, it seems that imap process is checking for the existence of ~/Mail, without expanding tilde. Then quite a bit later, it creates Mail as a "side effect" of creating Trash subdirectory. Relevant fragments: 1853 imap CALL mkdir(0x8a79b100,0x1f8) 1853 imap NAMI "~/Mail" 1853 imap RET mkdir -1 errno 2 No such file or directory 1853 imap CALL sigprocmask(0x1,0xffffffff) 1853 imap RET sigprocmask 0 1853 imap CALL mprotect(0x3c0ec000,0x1000,0x3) 1853 imap RET mprotect 0 1853 imap CALL mprotect(0x3c0ec000,0x1000,0x1) 1853 imap RET mprotect 0 1853 imap CALL sigprocmask(0x3,0) 1853 imap RET sigprocmask -65793/0xfffefeff 1853 imap CALL mkdir(0x8a79b108,0x1f8) 1853 imap NAMI "~" 1853 imap RET mkdir 0 1853 imap CALL mkdir(0x8a79b100,0x1f8) 1853 imap NAMI "~/Mail" 1853 imap RET mkdir 0 and 1853 imap CALL stat(0x8a79b180,0xcfbeb5c0) 1853 imap NAMI "/home/vmail/ppgk.com.pl/testms/Mail/Trash" 1853 imap RET stat -1 errno 2 No such file or directory 1853 imap CALL stat(0x8a79b1b0,0xcfbeb600) 1853 imap NAMI "/home/vmail/ppgk.com.pl/testms/Mail/Trash" 1853 imap RET stat -1 errno 2 No such file or directory 1853 imap CALL mkdir(0x8a79b1e0,0x1f8) 1853 imap NAMI "/home/vmail/ppgk.com.pl/testms/Mail" 1853 imap RET mkdir 0 1853 imap CALL open(0x8a79b1b0,0xa02,0x1b0) 1853 imap NAMI "/home/vmail/ppgk.com.pl/testms/Mail/Trash" 1853 imap RET open 7 My configuration is prtty much the same as previously: openbsd 3.9, i386, dovecot 1.0-rc27 (latest nightly, but the same happened in stock 1.0rc27) dovecot.userdb: testms::10000:10000:imap,,,:/home/vmail/ppgk.com.pl/testms/./::userdb_mail=mbox:~/Mail:INBOX=/home/vmail/ppgk.com.pl/%u/inbox dovecot.passdb: testms:{PLAIN}test: base_dir: /var/dovecot/ protocols: imap imaps pop3 pop3s ssl_listen: * ssl_ca_file: /etc/ssl/cert_bundle.pem ssl_cert_file: /etc/ssl/ca_ppgk/certs/fetch_crt.pem ssl_key_file: /etc/ssl/ca_ppgk/private/fetch_key.pem verbose_ssl: yes login_dir: /var/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 login_greeting: Dovecot IMAP server ready. login_greeting_capability(default): yes login_greeting_capability(imap): yes login_greeting_capability(pop3): no valid_chroot_dirs: /var/mail:/home/regular:/home/vmail verbose_proctitle: yes first_valid_uid: 1999 first_valid_gid: 10 mail_location: mbox:~/Mail:INBOX=/var/mail/%u mail_debug: yes fsync_disable: yes lock_method: fcntl maildir_copy_with_hardlinks: yes mbox_read_locks: fcntl mbox_write_locks: fcntl mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /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 imap_client_workarounds(default): outlook-idle delay-newmail imap_client_workarounds(imap): outlook-idle delay-newmail imap_client_workarounds(pop3): outlook-idle pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: mechanisms: plain login verbose: yes debug: yes passdb: driver: passwd-file args: /etc/dovecot.passdb passdb: driver: bsdauth userdb: driver: passwd-file args: /etc/dovecot.userdb userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master:
