[Dovecot] Coredump using virtual folder.
by Matthias Rieber 17 Apr '09

17 Apr '09

Hi, I'm using dovecot 1.2rc2 and I have the following issues with the virtual folder: 1. The virtual folders are flagged with \Noselect and at least thunderbird does not offer to select them. Adding them to the subscriptions file works fine and the folder can be used after that. 2. Two basic virtual work just fine like: $ cat virtual/all/dovecot-virtual INBOX INBOX.Ordner.work.archive.* all and $ cat virtual/unseen/dovecot-virtual INBOX unseen But the third one does not work: $ cat virtual/talk/dovecot-virtual virtual.all inthread x-references2 x-mailbox INBOX The IMAP Client says Unkown server error, the server logs look like this: ... dovecot: Info: IMAP(matthias): virtual: data=~/Maildir/virtual dovecot: Info: IMAP(matthias): fs: root=/home/matthias/Maildir/virtual, index=, control=, inbox= dovecot: Info: IMAP(matthias): Namespace INBOX.: Using permissions from /home/matthias/Maildir: mode=0700 gid=-1 <access happens here> dovecot: Info: IMAP(matthias): Loading modules from directory: /usr/local/lib/dovecot/imap dovecot: Info: IMAP(matthias): Module loaded: /usr/local/lib/dovecot/imap/lib20_fts_plugin.so dovecot: Info: IMAP(matthias): Module loaded: /usr/local/lib/dovecot/imap/lib20_virtual_plugin.so dovecot: Info: IMAP(matthias): Module loaded: /usr/local/lib/dovecot/imap/lib20_zlib_plugin.so dovecot: Info: IMAP(matthias): Module loaded: /usr/local/lib/dovecot/imap/lib21_fts_squat_plugin.so ... kind regards, matthias

[Dovecot] virtual domains with SQL auth + ntlm (winbind) auth for one of them...
by Tomasz Lutelmowski 16 Apr '09

16 Apr '09

Hello ! Is it possible to configure dovecot so it can use SQL authentication for set of domains, and ntlm authentication for one domain? In other words, I would like to authenticate all users (with user(a)domain.com as login) in SQL server, and if not found, then strip @windomain.com from login and fallback to pam->winbind authentication. So far i have in my dovecot.conf: auth_default_realm = windomain.com mechanisms = plain passdb sql { args = /etc/dovecot/dovecot-sql.conf } passdb pam { } passdb passwd { } userdb sql { args = /etc/dovecot/dovecot-sql.conf } userdb passwd { } userdb prefetch { } in pam.d/dovecot : auth required pam_nologin.so auth include system-auth-winbind account include system-auth-winbind session include system-auth-winbind With this configuration I can authenticate all users for virtual domains with logins user(a)domain.com - ok, then it fallbacks to pam - ok, but then it returns error (winbind uses only "user" or "DOMAIN\user" as login). After I set auth_username_format = %n I get opposite situation - I can authenticate users with pam, but I can't with SQL (it requires user@domain as login field). Unfortunately auth_default_realm = windomain.com is a must have (and most of the windows clients uses user(a)windomain.com as login anyway). Please help, I'm banging my head against keyboard since 3 days but still no idea how to do it. Best regards, Tomek

[Dovecot] dovecot SASL + Postfix no IMAP or POP3
by Roderick A. Anderson 16 Apr '09

16 Apr '09

A customer is suffering with an older version of a Windows "Mail Server" software that does not permit connections to _other_ ports (25 only). Several of the domains they host have users who's ISPs block port 25 so they can not send mail. They'd like to set up an outbound (relay?) SMTP server for those customers using per user(a)domain.tld authentication. Since I personally use Postfix with dovecot SASL I'd prefer doing the same for them. The only issue I see is how to "disable" IMAP and POP3 and use only the SASL authentication feature. I read that Timo is thinking to _someday_ :-) separate the SASL authentication from the rest of Dovecot, but in the mean time can I just leave out the IMAP and POP3 stuff from dovecot.conf, or is there a disable option? Of course I'll clamp the IMAP and POP3 ports down with iptables but it would be nice knowing Dovecot would just say go away or ignore those connections. Is anyone doing this or have any suggestions, thoughts, or ideas about it? \\||/ Rod --

[Dovecot] INBOX lost in virtual namespace
by Xueron Nee 16 Apr '09

Hi, I have set a virtual namespace to create Virtual POP3 INBOX follow: http://wiki.dovecot.org/Plugins/Virtual dovecot.conf: mail_location = maildir:~/Maildir # default namespace namespace private { separator = / prefix = list = yes hidden = no subscriptions = yes } # virtual mailbox, for pop3 namespace private { separator = / prefix = virtual/ location = virtual:~/Maildir/virtual:LAYOUT=maildir++ list = no hidden = yes } # Copy of the default namespace. We'll use this in dovecot-virtual file. namespace private { separator = / prefix = secret/ list = no hidden = yes subscriptions = no } # cat ~/Maildir/virtual/.INBOX/dovecot-virtual secret/* all but, the INBOX lost in secret/ namespace :( When list in IMAP: a1 list "" "*" * LIST (\HasNoChildren) "/" "Sent" * LIST (\HasNoChildren) "/" "Spam" * LIST (\HasNoChildren) "/" "Junk" * LIST (\HasNoChildren) "/" "Draft" * LIST (\HasNoChildren) "/" "Trash" * LIST (\HasNoChildren) "/" "INBOX" a1 OK List completed. a1 list "secret/" "*" * LIST (\HasNoChildren) "/" "secret/Sent" * LIST (\HasNoChildren) "/" "secret/Spam" * LIST (\HasNoChildren) "/" "secret/Junk" * LIST (\HasNoChildren) "/" "secret/Draft" * LIST (\HasNoChildren) "/" "secret/Trash" a1 OK List completed. INBOX lost, So, the virtual namespace for POP3 cannot see the messages in IMAP's INBOX. Am I doing anything wrong? Thanks.. -- Xueron Nee http://www.xueron.com

Oh, that was fun. Making the change below resulted in mail getting deferred with "Fatal: destination user parameter (-d user) not given" ... which apparently is caused by running deliver as 'root'! (http://archive.netbsd.se/?ml=dovecot-general&a=2008-02&t=6558196) So I am back to: -rwxr-xr-x 1 root dovecot 4044835 2009-04-03 13:52 deliver which doesn't produce the error and delivers the mail. Still no joy with Postfix+Spamassassin+Dovecot. This is unbelievably hard to get going. I started with the default installations of everything on a brand new system. I only made minimal changes as indicated by the docs. Then I made small changes as indicated by this and other mailing lists. I always reverted back to the original defaults between each effort. Now I'm just stumped. I'm not a newbie ... I've been administrating public servers for over 10 years, and using and working on the Internet since 1968! This is just the first time I've tried to use Postfix+Spamassassin+Dovecot. Previous installations have all used Sendmail+Spamassassin+Dovecot with zero issues. I want the benefits of using the Maildir storage system, but the past two weeks of trying to get this going are making me question whether that benefit is worth it. Can anyone please post their successful Postfix+Spamassassin+Dovecot setup for me to learn from? I would really appreciate it.

I've been messing with this for too long, now, and I'm blind to whatever's wrong. Or I'm simply being dense. Either way, I need help with a common issue. I'm trying to get Postfix+Spamassassin+Dovecot going on Fedora 10. (I'll get back to the global Sieve thingy soon, but I need to get this going, first.) When using the simple: mailbox_command = /usr/local/libexec/dovecot/deliver everything is cool, except there's no Spamassassin involvement, obviously. The problem shows itself when the Spamassassin user hands off to the recipient user and Deliver + the recipient user tries to access /var/run/dovecot/auth-master. Thank you for any insight you can provide. /var/run/dovecot: 755 root:dovecot /var/run/dovecot/login: 750 root:dovecot /var/run/dovecot/auth-master: 750 root:dovecot (I think. auth-master is a temporary file?

i plan to switch from uw-imap to dovecot on a couple of medium size systems and so i have written a conversion tool that understands mbox, mbx, and mix formats and converts to maildir format while trying to preserve uid info, keywords, flags, subscriptions, etc. it seems to work for me now, but i think some feedback might be useful. so if you have some files to convert and a desire to help, please download: http://www.spiretech.com/~joey/uw2dovecot.pl and give it a whirl. it is very sparsely documented right now but isn't too complex (yet). by default it copies your INBOX, mail dir, and .mailboxlist info into Maildir. those filenames can be overridden. i'd suggest running with -v to watch it. it requires that the output directory not exist before starting, so it should be relatively safe. it doesn't lock any files being read, so an active uw tree could cause it indigestion. it's designed to run while inbound mail and pop/imap sessions are disabled. it uses a few perl modules, but they should be standard with perl itself. it does do everthing in memory, so the largest message you have will be in memory and will be duplicated at least once as crlf pairs are replaced. also, this assumes you'll change the uid format in dovecot.conf to %08Xu%08Xv so that it doesn't change uids for the clients. send feedback to me and cc the list if you feel it useful. once this is stable, i'll get it added to the dovecot wiki.

[Dovecot] Handling ENFILE
by Mike Abbott 14 Apr '09

14 Apr '09

My mail server consumed all of its configured file table slots and started returning ENFILE ("Too many open files in system") for many operations. This wreaked havoc with dovecot-1.1.13. Here are some areas where dovecot should detect and more gracefully handle ENFILE error returns: 1. Deliver should report an error more helpful than "Unknown internal error" when fdatasync_path fails: deliver(user): Apr 10 14:53:20 Error: fdatasync_path(/Volumes/MailData/ user/new) failed: Too many open files in system deliver(user): Apr 10 14:53:20 Info: msgid=<...>: save failed to INBOX: BUG: Unknown internal error 2. Index files should not be fscked when they could not be opened due to ENFILE: Error: IMAP(user): open() failed with index file /Volumes/MailData/ user/.Deleted Messages/dovecot.index: Too many open files in system Warning: IMAP(user): fscking index file /Volumes/MailData/ user/.Deleted Messages/dovecot.index 3. Dovecot should not crash when mail transaction logs become corrupt, or appear to have become corrupt due to ENFILE. Here is a sequence of error messages from the log but I can't tell whether the IMAP ones up through the panic in the middle are all from the same process, or from different processes. deliver(user): Apr 10 14:55:32 Info: msgid=<...>: saved mail to INBOX deliver(user): Apr 10 14:55:54 Error: open() failed with index file / Volumes/MailData/user/dovecot.index: Too many open files in system deliver(user): Apr 10 14:55:54 Error: open() failed with file /Volumes/ MailData/user/dovecot.index.log.2: Too many open files in system deliver(user): Apr 10 14:55:57 Error: open() failed with index cache file /Volumes/MailData/user/dovecot.index.cache: Too many open files in system dovecot: Apr 10 14:56:08 Warning: IMAP(user): fscking index file / Volumes/MailData/user/dovecot.index dovecot: Apr 10 14:56:16 Error: IMAP(user): Fixed index file /Volumes/ MailData/user/dovecot.index: log_file_seq 15 -> 2 deliver(user): Apr 10 14:56:19 Info: msgid=<...>: saved mail to INBOX deliver(user): Apr 10 14:56:20 Error: Corrupted transaction log file / Volumes/MailData/user/dovecot.index.log seq 2: record size too small (type=0x0, offset=23088, size=0) (sync_offset=36848) deliver(user): Apr 10 14:56:20 Warning: fscking index file (in-memory index) deliver(user): Apr 10 14:56:21 Info: msgid=<...>: save failed to INBOX: Internal error occurred.

[Dovecot] Issue with converting users from cyrus user.domain.com
by Preston Lord 13 Apr '09

13 Apr '09

I have been using cyrus for the past 6 years, but it is a pain to config. So ... I just installed dovecot 1.0.15 on a new debian 4r7 box. In cyrus we were using usernames as "user.domain.tld". In dovecot I realize I can: auth_username_translation = .@ But this converts user.domain.tld to user@domain@tld which of course fails. Is there a regex or something I can apply to pull this off? I also tried auth_username_format = %n.%d But I think this does the opposite of what I need. Any help is GREATLY appreciated. Thanks in advance P.

[Dovecot] deliver vs lda
by Timo Sirainen 12 Apr '09

12 Apr '09

deliver is the binary name. but it's configured inside protocol lda {} section. This is getting annoying, any thoughts on what would be a good unifying name? a) deliver binary, protocol deliver {} b) lda binary, protocol lda {} c) dovecot-lda binary, protocol lda {} d) mda binary, protocol mda {} e) dovecot-mda binary, protocol mda {} f) something else? In any case protocol lda {} would work for a while longer for backwards compatibility. c) and e) choices also makes me think if e.g. imap and imap-login should be called dovecot-imap and dovecot-imap-login instead. People have had trouble finding them since ps|grep dovecot doesn't find them..

tonight dovecot 1.2beta4 crashed for the first time with an assertion failed. See attached log file. Around that time nobody was logged in into dovecot and there were no other mail deliveries going on.

[Dovecot] Postfix + Dovecot + Sieve + SpamAssassin
by Sascha Scandella 10 Apr '09

10 Apr '09

Hello Until now I used Postfix in combination with Procmail and Dovecot. I am convinced that the Dovecot Sieve plugin is a much more elegant solution. So I changed to Postfix + Dovcecot Deliver + Dovecot + Sieve. If I understood correctly I cannot call other applications within a Sieve script. Until now I used Procmail to filter Spam Messages with SpamAssassin. Is there a possibility to filter spam messages before/after Dovecot deliver. I want to use the users .spammassassin user_prefs located in their home folder. I suppose if I use a content filter in Postfix this is to early, since the user is not known at that moment. Or am I wrong? Any help is highly appreciated. Best regards, Sascha

hi list, I'd like to know about "Status" to the header on dovecot.

Which one is the reason of that cannot see "Status" to the header with evolution and thunderbird? - there isn't "Status" to the header - there is "Status" to the header, but just cannot see Thanks in advance.

[Dovecot] dbox problem
by Xueron Nee 09 Apr '09

09 Apr '09

Hi, I have just tested the dbox format mailbox, it works fine. But when I create dir through imap with `create` command, it only creates the dir onder ~/dbox/mailboxes, such as ~/dbox/mailboxes/newfolder. There was no `dbox-Mails` dir created. So the newfolder was 'noselect'. But the new folders created by `autocreate` plugin was correct. -- Xueron Nee http://www.xueron.com

[Dovecot] Indexing of mails to speed up the IMAP SEARCH command
by Tassilo Horn 09 Apr '09

09 Apr '09

Hi all, I use a local dovecot server which is synchronized with my two imap accounts using OfflineIMAP. This works very nice and is highly usable. But one thing I'd like to improve is the slow IMAP search. When I search for a string in the subjects of all messages in a mailbox using some mail client, dovecot seems to grep all the messages in there. Is there a way to let dovecot index more informations which are then used to speed up the SEARCH command? Bye, Tassilo

[Dovecot] Moving IMAP folders to NFS volume.
by Frank Bonnet 09 Apr '09

09 Apr '09

Hello Due to lack of disk space on local disks I need to move all our imap folders to a NFS volume ( NetAPP filer ) I have a question about Dovecot indexes , is it better to remove all of them before copying folders to the NFS volume and let Dovecot rebuild all indexes when users restart to access to their imap folders ? Thanks a lot.

[Dovecot] Upgrade from 0.99.x to 1.1.x
by Wolfram Schlich 09 Apr '09

09 Apr '09

Hi! I want to upgrade a Dovecot installation from 0.99.14 to 1.1.15, so I had a look at the following wiki article: http://wiki.dovecot.org/Upgrading?action=show&redirect=UpgradingDovecot The article http://wiki.dovecot.org/Upgrading/1.0 says something about .customflags -> dovecot-keywords and .subscriptions -> subscriptions change/conversion: http://wiki.dovecot.org/Upgrading/1.0#Subscriptions http://wiki.dovecot.org/Upgrading/1.0#Keywords Do I understand it correctly that when directly upgrading from 0.99 to 1.1, Dovecot does the subscriptions renaming but not the keywords renaming and conversion, but that when I manually rename all .customflags files to dovecot-keywords, it does the format conversion of that file automatically? Is there anything else what's important to note for such an upgrade? The system is using Maildir as the mailbox format and only local storage (no NFS etc.). -- Regards, Wolfram Schlich <wschlich(a)gentoo.org> Gentoo Linux * http://dev.gentoo.org/~wschlich/

[Dovecot] Multiple use of the same LDAP attribute
by Bernhard Schmidt 09 Apr '09

09 Apr '09

Hi, we've found a weird bug (?) in Dovecot 1.1.11. Since day and age we've been running dovecot for our student mailserver, getting the location of the mailbox from a LDAP directory. We allow login and LDA with both full mail address and an internal username, so the mailbox directory is based on a LDAP attribute user_attrs = xxxMailbox=mail=maildir:/home/mailstore/%U$/Maildir:INDEX=/home/mailstore/indexes/%1U$/%U$, uidNumber=vmail, gidNumber=vmail, xxxMailQuota=quota_rule2=*:storage=%$B this worked just fine until we introduced sieve, which made us realize we did not have the home directory set at all. The obvious and easy fix (we thought) was to set the home directory based on the xxxMailbox variable as well: user_attrs = xxxMailbox=mail=maildir:/home/mailstore/%U$/Maildir:INDEX=/home/mailstore/indexes/%1U$/%U$, uidNumber=vmail, gidNumber=vmail, xxxMailQuota=quota_rule2=*:storage=%$B, xxxMailbox=home=/home/mailstore/%U$ unfortunately, after this trivial change hell froze over, because suddenly the mail variable was not set at all anymore, and since we had set mail_location = maildir:/home/mailstore/%Uu/Maildir:INDEX=/home/mailstore/indexes/%1Un/%Un (based on username) it was suddenly delivered into the wrong folder (based on the supplied username, not on the LDAP attribute). Debug from after the change: Apr 8 13:53:39 lxmhs23 dovecot: auth(default): ldap(username(a)xxx.de): user search: base=<deleted> scope=onelevel filter=<deleted> fields=xxxMailbox,uidNumber,gidNumber,xxxMailQuota,xxxMailbox Apr 8 13:53:39 lxmhs23 dovecot: auth(default): ldap(username(a)xxx.de): result: xxxMailQuota(quota_rule2=*:storage=%$B)=*:storage=1073741824B xxxMailbox(home=/home/mailstore/%U$)=/home/mailstore/1636D8B1D7916DEA/ [...] Apr 8 13:53:39 lxmhs23 deliver(username(a)xxx.de): maildir: data=/home/mailstore/USERNAME@XXX.DE/Maildir:INDEX=/home/mailstore/indexes/U/USERNAME As you can see the mail variable wasn't set by LDAP at all. We did some more tests and found a workaround, when using another LDAP (mwnid) attribute that contains the same information it works just fine user_attrs = xxxMailbox=mail=maildir:/home/mailstore/%U$/Maildir:INDEX=/home/mailstore/indexes/%1U$/%U$, uidNumber=vmail, gidNumber=vmail, xxxMailQuota=quota_rule2=*:storage=%$B, mwnid=home=/home/mailstore/%U$ Apr 8 14:18:06 lxmhs23 dovecot: auth(default): ldap(username(a)xxx.de): user search: base=<deleted> scope=onelevel filter=<deleted> fields=xxxMailbox,uidNumber,gidNumber,xxxMailQuota,mwnid Apr 8 14:18:06 lxmhs23 dovecot: auth(default): ldap(username(a)xxx.de): result: xxxMailQuota(quota_rule2=*:storage=%$B)=*:storage=1073741824B xxxMailbox(mail=maildir:/home/mailstore/%U$/Maildir:INDEX=/home/mailstore/indexes/%1U$/%U$)=maildir:/home/mailstore/1636D8B1D7916DEA//Maildir:INDEX=/home/mailstore/indexes/1/1636D8B1D7916DEA/ mwnid(home=/home/mailstore/%U$)=/home/mailstore/1636D8B1D7916DEA Apr 8 14:18:06 lxmhs23 deliver(username(a)xxx.de): maildir: data=/home/mailstore/1636D8B1D7916DEA//Maildir:INDEX=/home/mailstore/indexes/1/1636D8B1D7916DEA/ So, it looks like there is an issue using the same LDAP attribute (xxxMailbox in this case) twice in variable expansion. Is this a known issue? Of course there are several viable workarounds (base mail location on home directory, use the second attribute), but this problem was pretty surprising. Bernhard

[Dovecot] Trying nonplaintext mech with LDAP password-hash
by dovecotlist＠encambio.com 09 Apr '09

09 Apr '09

Hello List, The only passdb block in /pfx/etc/dovecot/dovecot.conf is: passdb ldap { args = /pfx/etc/dovecot/dovecot-ldap.conf } In /pfx/etc/dovecot/dovecot-ldap.conf: auth_bind = no dn = cn=mymgr,dc=host,dc=tld dnpass = ******** default_pass_scheme = LDAP-MD5 In /pfx/etc/openldap/slapd.conf: password-hash {MD5} If I try: $ /pfx/bin/ldapsearch <...> \ | grep '^userPassword' \ | sed -e 's;.*:: $.*$$;\1;' \ | mimencode -u ...I get the correct password (MD5 hashed.) According to wiki.dovecot.org/AuthDatabase/LDAP/PasswordLookups this should work, and indeed when starting dovecot it does not complain about: 'CRAM-MD5 mechanism can't be supported with given passdbs' Instead it starts right up, but when a thunderbird client connects and tries authenticating with CRAM-MD5 it fails. In the wiki page 'PasswordLookups' it mentions: Supports non-plaintext authentication mechanisms (if returning plaintext/properly hashed passwords). I've already verified that this works correctly with plaintext (CLEARTEXT in slapd.conf), but I really want to store the passwords in LDAP using some hash. Why doesn't LDAP-MD5 work as advertised? What did the author mean by 'properly hashed passwords'? Thanks. -- Eduard

[Dovecot] Dovecot 1.1.11 failing to accept SSL/TLS connections
by Mike Brudenell 08 Apr '09

08 Apr '09

Greetings - We are running Dovecot 1.1.11 on our servers and have been gradually migrating people off our old (UW-based) systems onto the new (Dovecot-based) ones. As a result the new systems are seeing more connections from more people. We have started seeing problems reported by users of our webmail service that they are getting an error indicating the webmail software (Prayer) has failed to establish an IMAP connection using TLS to Dovecot. Investigations show it is not just the webmail service that is affected but all mail clients: it's just other clients retry the connection, whereas Prayer fails the login and shows the error message: TLS/SSL failure for username.imap.york.ac.uk: SSL negotiation failed It seems to be related to one of Dovecot's imap-login processes getting a lot of file descriptors in use. We initially spawn off 10 imap-login processes and have each handling 256 connections. Full "dovecot -n" at the end of the message, but the relevant settings here are: login_process_size = 64 login_process_per_connection = no login_processes_count = 10 login_max_processes_count = 128 login_max_connections = 256 We have grown to suspect it is to do with one of the imap-login processes having a large number of files open. Killing the process seems to get rid of the problem. For example currently we have 11 imap-login processes running, one of which has 518 open files -- process 12436 in the list below. I suspect that, as in previous times we've encountered the problem, killing this process will alleviate the problem. (I'll be doing this later on this evening.) It is slightly odd that the imap-login processes have a very skewed distribution of open files, almost as if the algorithm for allocating connections to a process favours some over others. For example the current counts of open files are: Pid = Open files count 12430 = 42 26818 = 237 12431 = 90 12433 = 12 12438 = 304 12437 = 106 12435 = 190 12432 = 14 12436 = 518 12434 = 32 12429 = 12 Process 12436 was one of the 10 imap-login processes initially created back on March 3rd. (Process 26818 was the additional imap-login process spawned a little later on March 4th.) I don't believe the problem lies with the available file descriptors on the system: in the script which starts Dovecot I do date >/var/run/dovecot-limits ulimit -Sa >>/var/run/dovecot-limits echo "----------" >>/var/run/dovecot-limits ulimit -Ha >>/var/run/dovecot-limits ulimit -Sn 10128 echo "==========" >>/var/run/dovecot-limits ulimit -Sa >>/var/run/dovecot-limits echo "----------" >>/var/run/dovecot-limits ulimit -Ha >>/var/run/dovecot-limits $DOVECOT >>/var/run/dovecot-limits 2>&1 (The magic 10128 number came from Dovecot 1.1.11 itself, complaining that the number I had originally was too low.) Likewise the output of the pfiles command on process 12436 (which is the one I believe to be problematic) indicates its limit still has some available -- I'm guessing Dovecot has reduced the limit down to 533 from the 10128 set in the startup script: Current rlimit: 533 file descriptors We originally saw this problem with Dovecot 1.0.3 which we were running up until a couple of weeks ago. From there I upgraded first to 1.0.15 and then to 1.1.11. I'd hoped that upgrading would fix the problem: I see it has been mentioned before on the list, but not for a year or two. Can anyone give any help, please?

[Dovecot] Prohibit removing INBOX
by floss＠pbartels.info 08 Apr '09

08 Apr '09

Hello list, I'm using dovecot 1.1.11 and I'm going to prohibit users to remove their INBOX and some other directories in the mailbox root. I used Access Control Lists (http://wiki.dovecot.org/ACL) to do this: protocol imap { mail_plugins = acl } plugin { # With global ACLs in /etc/dovecot/acls/ directory: acl = vfile:/etc/dovecot/acls } /etc/dovecot/acls/.DEFAULT: owner lrwstie /etc/dovecot/acls/INBOX/.DEFAULT owner lrwstiekxa Actually - its not possible to create/remove directories under the mailbox root - its possible to create directories under INBOX - its NOT possible to remove directories under INBOX (This is my problem.) I tried symlinks like: /var/mail/.../INBOX/dovecot-acl -> /etc/dovecot/acls/INBOX/.DEFAULT /var/mail/.../dovecot-acl -> /etc/dovecot/acls/.DEFAULT But I think the symlink won't help because they doesn't change anything. And even with the symlinks its not possible to remove directories under IBOX. The documentation says: > If a mailbox has both global and per-mailbox ACL file, both of them > are read and the ACLs are merged. If there are any conflicts: > * v1.0 and v1.1: The per-mailbox ACL file overrides global ACL file. As far I can see it the documentation says nothing about merging ACLs of subdirs. But it seems the given behavior is not wanted by the dovecot design, because it seems it should be possible to override ACLs for subdirs, also give more permissions than the upper dirs. Is this a dovecot failure, do I miss something or is it really wanted by dovecot this way? My MUA (Evolution) says: > Cannot delete folder "INBOX/test". > Because "IMAP command failed: Permission denied". It unsubscribes the folder but it not able to remove it.

[Dovecot] Dovecot, LVS and the issues I have with it.
by neil 08 Apr '09

08 Apr '09

We run around 5 dovecot (debian etch 1.0.rc15) POP/IMAP 'nodes' using the LVS load balancer and an NFS based SAN. it works pretty well. I love the robustness of load balancing POP/IMAP. We do a reasonable amount of throughput through these especially at peak times pushing our SAN to around 1.5k IOP/s We currently have two issues with this setup. One of which is NFS index corruption issues we get due to NFS/dovecot locking. Basically the UUID list or a .index gets corrupt. This causes a full re-indexing of the mailbox / broken mailbox until i delete the indexes. In the UUID lists case the symptom tends to effect use who use POP rather than IMAP and insist on keeping messages on the server. Because it's corrupt it gets rebuilt one way or the other and the users email client proceeds to redownload the entire mailbox again until he remarks them to be saved. This tends to annoy the user a lot. After a bit of testing we do however expect this to be fixed by version 1.1. However if anyone has any comments on this I would certainly be interested. The other issue is a little tricky to describe or even log effectively. Occasionally a node basically receives more connections than it is able to handle. The connection count goes through the roof for that node. It will go up way beyond 150 dovecot authentication threads and 100 or so active POP/IMAP dovecot threads. The IO_wait/cpu and memory usage also tends to be spiking at this point. The server gets to the tipping point where it can no longer serve it's POP/IMAP requests fast enough compared to the number of connections it's getting. I'd be fine with this but this creates some less than desirable symptoms: 1. We obviously reach the auth thread cap eventually so any new auth requests basically get refused by the server. To the user this is a seen as an outlook/mail client re-auth pop-up request. This annoys them. Ideally if the server stops accepting auth requests it should fall off our load balancer until it can consistently accept them again. Since the LVS detects a node fail by whether the tcp port is still open this doesn't happen, since dovecot keeps the port open. This is obviously more an LVS issue and not for this mailing list I expect unless anyone has any config tweaking tips here? 2. Now here's my real gripe. Dovecot does not handle running out resources very gracefully at all in our setup. It does start killing threads after a while. I get multiple *"dovecot: child 17989 (login) killed with signal 9". *I'm not exactly sure what's going on here because after this all I can see is the machine totally out of memory and the kernel starts killing absolutely everything. All services are killed (including ssh etc..) and I plug a monitor into the server and find the last few lines of the console listing init and other rather important things having just been killed. At this point it is a case of power cycling the server and all is back to normal again. I imagine there's not a huge amount of people using dovecot in this way. But anyone got any recommendations here? I really like using dovecot in this setup it handles it pretty well and the redundancy and functionality options it provides have been invaluable. Neil

[Dovecot] Global Sieve File
by James Butler 08 Apr '09

08 Apr '09

Is anyone here using a global Sieve file that handles messages for an entire server with many users? I understand and use local Sieve files, but I would like to learn more about how to set up Sieve to filter ALL incoming messages using a single file. I would love to read about how you managed to get it working. I'm running Fedora 10 with Postfix 2.5.5 and Dovecot 1.2.rc2. Thanks for any insight! James

[Dovecot] Compiling v1.3 on different OSes
by Timo Sirainen 08 Apr '09

08 Apr '09

I was hoping to finally get shared libdovecot.so and libdovecot-storage.so libraries for v1.3, so Sieve (and maybe others) could link against them. But I'm running into trouble getting it to compile in Solaris 10. Could you non-Linux users test if this compiles with you? http://dovecot.org/tmp/dovecot-1.3.UNSTABLE.tar.gz Or if anyone has ideas why this happens, I'd like to know: libtool: link: gcc -std=gnu99 -g -O2 -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -Wstrict-aliasing=2 -I/home/cras/include -o .libs/rawlog rawlog.o ../lib-dovecot/.libs/libdovecot.so -lrt -lsocket -lsendfile -Wl,-rpath -Wl,/usr/local/lib/dovecot ../lib-dovecot/.libs/libdovecot.so: undefined reference to `dlerror(a)SUNW_1.22' ../lib-dovecot/.libs/libdovecot.so: undefined reference to `dlopen(a)SUNW_1.22' ../lib-dovecot/.libs/libdovecot.so: undefined reference to `dlsym(a)SUNW_1.22' ../lib-dovecot/.libs/libdovecot.so: undefined reference to `dlclose(a)SUNW_1.22' If I disable plugins (so dl*() functions aren't used) it compiles, so it's only those functions that are problematic. pvs -s /lib/libc.so lists the dl* functions under SUNW_1.22 so I'd think that should have worked..

[Dovecot] v1.3 plugin locations
by Timo Sirainen 07 Apr '09

07 Apr '09

It's getting more and more annoying to have separate plugin directories for lda, pop3 and imap. Currently all the plugins are installed into $lib/dovecot/ and then symlinked to the lda, pop3, imap directories. The original reason was that v0.99 just loaded everything in those directories since there was no mail_plugins setting. But then there are things like expire-tool and convert-tool (and the upcoming doveadm) that don't load plugins at all, even though they probably should. Adding just more directories to them seems to be pointless. Also SQL plugins are shared by dovecot-auth and dict and those would need symlinking.. And in future you might want to load SQL plugins to e.g. imap process. So, I was planning on just putting everything into $lib/dovecot/. expire-tool etc. would use mail_plugins setting that wasn't inside protocol {}. So for example: mail_plugins = quota protocol lda { mail_plugins = quota sieve } protocol imap { mail_plugins = quota imap_quota } protocol pop3 { # defaults to mail_plugins=quota above, no need to set it explicitly } That leaves auth and dict.. I was considering adding new auth_plugins and dict_plugins settings, but that might make it more difficult to start using distro-compiled Dovecot where sql, ldap, etc. are in plugins. So perhaps the auth/ and dict/ directories can stay and contain symlinks. But the $lib/dovecot/sql/ directory could go away and the sql plugins be stored just in $lib/dovecot/ among everything else. Any thoughts?

[Dovecot] Compile and configure Solr plugin
by Rui Carneiro 07 Apr '09

07 Apr '09

Hi all, I'm having some kind of troubles on Solr's integration. I configured Dovecot with the Solr argument (--with-solr) and everything proceeded just fine. But, when I started Dovecot I got this error: Plugin fts_solr not found from directory /usr/lib64/dovecot/modules/imap Error: imap dump-capability process returned 89 Fatal: Invalid configuration in /etc/dovecot/dovecot.conf In fact, there is no Solr plugin in that directory. So I tried to make a symbolic link from where the compiled Solr plugin was to this directory: ln -s /usr/local/lib/dovecot/lib21_fts_solr_plugin.so And now I have the following error: dlopen(/usr/lib64/dovecot/modules/imap/lib21_fts_solr_plugin.so) failed: /usr/lib64/dovecot/modules/imap/lib21_fts_solr_plugin.so: undefined symbol: mailbox_get_virtual_box_patterns Couldn't load required plugins Error: imap dump-capability process returned 89 Fatal: Invalid configuration in /etc/dovecot/dovecot.conf I'm missing some steps in this installation for sure, do anyone have any clue?

[Dovecot] Modified websieve for use with dovecot
by Wolfgang.Friebel＠desy.de 07 Apr '09

07 Apr '09

In order to let users construct a sieve filter using a GUI I have taken websieve.pl from Alain Turbide (for use with Cyrus) and modified it to work with dovecot. In order to get it working quickly I have removed all the code I did not need (e.g. ldap support, password authentication) and coded Kerberos5 auth (via GSSAPI or SASL) in. I understand that this makes the work mostly useless to others. As however the dovecot adaptations were done by removing internally used perl packages by ones on CPAN such as Mail::IMAPClient and Net::Managesieve that part of the code should be of a broader interest. If someone is interested to have a look or even wants to help make it again a more universal tool I have put the code on ftp://ftp-zeuthen.desy.de/pub/unix/mail/websieve.pl Current status: I have tested the creation and modification of sieve rules, inspecting and setting ACL's (dovecot 1.2), displaying quota and creating folders. All the other code (e.g. the part that deals with an administrative user) is untested and probably not compatible yet with the new perl modules used. -- Wolfgang Friebel Deutsches Elektronen-Synchrotron DESY Phone/Fax: +49 33762 77372/216 Platanenallee 6 Mail: Wolfgang.Friebel AT desy.de D-15738 Zeuthen Germany

[Dovecot] Script to install dovecot 1.2 plus Managerootsieve to CentOS5.2
by Bruce A. Mallett 07 Apr '09

07 Apr '09

I have no idea if this is of interest to anyone but it might save you some work .. I created a script that will install Dovecot 1.2-rc2 (currently) to a CentOS5.2 installation complete with Stephan Bosch's Managesieve, postfix, virtual users, LDAP, and LDAP personal address books. Oh right! .. and Squirrelmail plus various plugins (change LDAP password, LDIF import, Avelsieve). Also self-signed certificates are created from data supplied in a configuration file. I've stuck the required files here: http://www.nightstorm.com/~bam/CentOS5.2/ I did an install to a 32 bit CentOS so it has worked at least once on that architecture. It *should* work on a 64 bit as well (I provide the RPM) but I've not personally tested it. I am by no means an expert on any of this stuff (particularly the security aspects), so I'd certainly welcome any suggestions for ways to improve on the installation, the script, life, the universe, ... ;-) - Bruce

[Dovecot] Implementation of editheaders in dovecot
by Konstantin Lepa 06 Apr '09

06 Apr '09

Hello. I wrote the hook function for deliver. I want to add support of editheaders in the plug-in for dovecot. For this purpose I wrote the function rarules_get_stream. Remover of headrs works properly, but adding does not work. I took Timo Sirainen's advice from http://markmail.org/message/skb6arnll5gaopdr . Do I use a correct way of creation of a message? I give backtrace and a part of my code.

[Dovecot] is it possible to recover files from a dovecot.inboxe.cache file?
by Alfred Nutile 06 Apr '09

06 Apr '09

I found this file in the mail boz and noticed it had 20 emails in it (though you can only read really the header the body is cryptic cause it is a bin file?) Just not sure if I can and how to use this to restore the lost emails in that inbox. Thanks

[Dovecot] Segfault in Sieve 1.2
by Bernhard Schmidt 06 Apr '09

06 Apr '09

Hello, two days ago I've upgraded to 1.2rc2 and the new sieve implementation (version 0.1.4). Today I got the first mail that got stuck in the postfix queue because deliver was dying with a segfault. The mail is spam, thus I don't have any issues sharing it: http://users.birkenwald.de/~berni/temp/deliver-segfault.mail It happens with this small sieve script (my normal one is larger, but this is the part that triggers the segfault): http://users.birkenwald.de/~berni/temp/deliver-segfault.sieve Note that I've been running this script unaltered for months, first with Dovecot 1.1 and CMUSieve and now with various versions of Dovecot 1.2 and the new sieve implementation for about three weeks, this is the first mail that got stuck. I got a coredump, but without debugging symbols it doesn't tell that much. If you can't reproduce it I'll compile it with debugging symbols and try again.

[Dovecot] THREAD X-REFERENCES2 index bug?
by Nathan Kinkade 04 Apr '09

04 Apr '09

Hi all, $ sudo dovecot --version 1.2.beta3 I just started using Dovecot a few weeks ago, and my client is also using the X-REFERENCES2 thread algorithm. The client is misbehaving when trying to list messages in my INBOX, but only when a threaded message exists. I have tracked it down to the thread index that Dovecot is returning, but the problem is only extant when using the X-REFERENCES2 thread algorithm. Here is a snippet of transcript from imap client that comes with Dovecot: $ export MAIL=maildir:~/Maildir:INBOX=~/Maildir/INBOX $ /usr/lib/dovecot/imap <snip> 1 SELECT "INBOX" <snip> 2 THREAD X-REFERENCES2 UTF-8 ALL * THREAD (0)(2)(1 3)(4) 2 OK Thread completed. There are, in fact, only 4 messages in my INBOX, and the reference to (0) seems spurious. When I do the same test, but passing REFERENCES instead of X-REFERENCES2 Dovecot returns an index which I believe to be correct: <snip> 2 THREAD REFERENCES UTF-8 ALL * THREAD (1 3)(2)(4) 2 OK Thread completed. <snip> Is this the normal and expected behavior of X-REFERENCES2 that the client just needs to take into account, or is the reference to thread index (0) an error? Thanks! Nathan

http://dovecot.org/releases/1.2/rc/dovecot-1.2.rc1.tar.gz http://dovecot.org/releases/1.2/rc/dovecot-1.2.rc1.tar.gz.sig I think it's time to get v1.2.0 out soon. Shared mailbox code is beginning to look like it's working and other features should work fine also. I don't really see any reasons to delay it, so please start testing and let's get the last bugs found and fixed quickly. I'm also going to start v1.3 branch soon with configuration rewrite and multi-dbox support. Changes since beta4: * Renamed THREAD X-REFERENCES2 to THREAD REFS (from INTHREAD draft) + When a process is killed, show the signal code and the sending process's pid and uid. + quota-fs: Added support for NFS group quota. - Several fixes to shared mailboxes and ACLs - Removed umask setting. We're nowadays creating practically all files with proper umasks. - acl: Dropped default ACL cache timeout from 5 minutes to 30 seconds. - fts-solr fixes - virtual mailbox fixes - Write to main index file less often.

[Dovecot] Missing mail_max_userip_connections setting
by Thomas M Goerger 03 Apr '09

03 Apr '09

Hi, I'm having a problem with a webmail client trying to open multiple IMAP connections with dovecot, and hitting a cap. I see from the error logs from this program that it's hitting the mail_max_userip_connections cap, but I'm not seeing this value as defined in the dovecot.conf file. Would this automatically get set to a certain value by default if it's not present? Thanks, ************************************************************************* * Tom Goerger - Email/Unix System Administrator * * * * University of Minnesota Email: tmg(a)umn.edu * * Operations, Infrastructure and Architecture Phone: 4-5804 * * Internet Services Office: 626J WBOB * * * *************************************************************************

[Dovecot] Maildir files with mtime in the future
by Holger Weiss 03 Apr '09

03 Apr '09

If Maildir storage is used, the mtime of a given Maildir file is set to the message's INTERNALDATE. Now, when a client APPENDs a message to an IMAP mailbox, the client may optionally specify the INTERNALDATE: | If a date-time is specified, the internal date SHOULD be set in the | resulting message; otherwise, the internal date of the resulting | message is set to the current date and time by default. [ ftp://ftp.fu-berlin.de/doc/rfc/rfc3501.txt (6.3.11. APPEND Command) ] However, if the client does so, Dovecot will set the mtime of the Maildir file in question to the date specified by the client even if it's in the future. Since files with an mtime in the future can cause all sorts of trouble (e.g., they might get backed up repeatedly by incremental backups), it would be nice if Dovecot would (optionally?) use the current time if the client specifies a time in the future. For example, we use the following patch: ---------- 8< ---------------------------------------- 8< ---------- diff --git a/src/imap/cmd-append.c b/src/imap/cmd-append.c index 0b22fd5..b7e42b9 100644 --- a/src/imap/cmd-append.c +++ b/src/imap/cmd-append.c @@ -319,6 +319,12 @@ static bool cmd_append_continue_parsing(struct client_command_context *cmd) return cmd_append_cancel(ctx, nonsync); } + if (internal_date != (time_t)-1 && internal_date > time(NULL)) { + /* the client specified a time in the future, set it to now. */ + internal_date = (time_t)-1; + timezone_offset = 0; + } + if (ctx->msg_size == 0) { /* no message data, abort */ client_send_tagline(cmd, "NO Can't save a zero byte message."); ---------- 8< ---------------------------------------- 8< ---------- Holger

[Dovecot] v 1.1.13 / GSSAPI / Timeout waiting for handshake from auth server
by Jahnke-Zumbusch, Dirk 03 Apr '09

03 Apr '09

Dear all, I am trying to setup Dovecot with GSSAPI support. For testing purposes gssapi is the only method allowed for login. As I cannot login to my mailbox, I'vo got two questions about the following log entries: dovecot: Info: auth-worker(default): passwd-file /dovecot/store/db/test-userdb: Read 3 users dovecot: Info: auth(default): new auth connection: pid=3915 dovecot: Info: auth(default): client in: AUTH 1 GSSAPI service=imap lip=131.169.*.* rip=131.169.*.* lport=143 rport=35779 dovecot: Info: auth(default): gssapi(?,131.169.40.218): Obtaining credentials for imap(a)my.host.name dovecot: Error: imap-login: Timeout waiting for handshake from auth server. my pid=3918, input bytes=0 1. I am puzzled about the credentials "imap(a)my.host.name" being obtained; shouldn't this be something like "imap/my.host.name(a)MY.REALM" ? 2. what does "Timeout waiting for handshake from auth server." mean? Who is trying to handshake with whom? Any ideas?

[Dovecot] Time moved backwards errors
by Bloke 03 Apr '09

03 Apr '09

Hello, I am experiencing a number of 'Time moved backwards errors' such as: Mar 27 11:38:20 host-78-129-239-60 dovecot: imap-login: Time just moved backwards by 729 seconds. This might cause a lot of problems, so I'll just kill myself now. http://wiki.dovecot.org/TimeMovedBackwards Mar 27 15:20:10 host-78-129-239-60 dovecot: Time just moved backwards by 4214 seconds. This might cause a lot of problems, so I'll just kill myself now. http://wiki.dovecot.org/TimeMovedBackwards Mar 29 11:08:59 host-78-129-239-60 dovecot: imap-login: Time just moved backwards by 4341 seconds. This might cause a lot of problems, so I'll just kill myself now. http://wiki.dovecot.org/TimeMovedBackwards on my Centos 5.2 openvz - based VPS I have raised the issue with my VPS provider, who are responding that 'the jury is still out' as to whether this is a system, or Dovecot problem. Reading the TimeMovedBackwards article on the Dovecot wiki, and the kernel mailing list thread referred to on it, it would seem quite apparent that this is caused by a failure of the gettimeofday() function to reliably return the correct value. If anyone has any advice as to how I could proceed to fix this (I currently have a watch on the Dovecot service which restarts it after any failures) or how I should best phrase this to get it resolved 'upstream' by the VPS provider, I would be very grateful. Thank you, Patrick Vale

[Dovecot] dbox benchmarks
by Timo Sirainen 03 Apr '09

03 Apr '09

http://hg.dovecot.org/dovecot-dbox-redesign/ Looks like multi-dbox scales pretty nicely. Even after 100k messages the peak saved msgs/sec is the same as the initial saved msgs/sec, even if the average slows down somewhat. I tested this by first deleting mailbox, then running "imaptest" for a second to get saving to start writing several fields to dovecot.index.cache file. Then ran imaptest for 60 seconds that did nothing but save messages using IMAP APPEND commands. The summary is that multi-dbox is almost 10x as fast as maildir when fsync is disabled and 2,5 faster with fsyncing: fsync_disable=yes: multi-dbox : ~1700 -> ~1500 msgs/sec, 90842 msgs/60 sec single-dbox: ~1700 -> ~1400 msgs/sec, 86149 msgs/60 sec maildir : ~330 -> ~110 msgs/sec, 9789 msgs/60 sec fsync_disable=no: multi-dbox : ~220 -> ~170 msgs/sec, 10113 msgs/60 sec maildir : ~100 -> ~70 msgs/sec, 4123 msgs/60 sec Also I just noticed that saving messages with two clients gets a peak of 2200 msgs/sec, most likely because two CPU cores can be used then. Hmm. I guess if there were no locking it should have reached 3400 msgs/sec, but it's better than no performance increase.

[Dovecot] An issue of I login my mail server from webmail client
by Alan Zheng 03 Apr '09

03 Apr '09

Dear all: I have a really strange issue, that is when I login my mail server from webmail client (I used SquirrelMail, by the way, I have modified squirrelmail's timeout value, that means not since squirrelmail timeout), I will got timeout issue when I login about 5PM ~ 10PM everyday (it works fine on other time, I also check my cron, that looks no problem), and during this time, I also cannot connect my 993 port with openssl like this: openssl s_client -connect myDomainName:993 But when I use mail client (such as outlook) to access dovecot, that works fine, and during 5PM ~ 10PM, my web site also works fine, and once I restart computer if I can not login during 5PM ~ 10PM from webmail client. that will work fine. can you try to help me? below is my configure of dovecot. *dovecot -n # 1.0.7: /etc/dovecot.conf log_path: /var/run/dovecot/maillog info_log_path: /var/run/dovecot/maillog protocols: imaps ssl_parameters_regenerate: 0 verbose_ssl: yes login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login mail_location: maildir:~/Maildir mail_debug: yes auth default: mechanisms: plain login passdb: driver: pam userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix plugin: convert_mail: mbox:~/Mail:INBOX=/var/mail/%u* -- Best Regards Alan Zheng

[Dovecot] Dovecot ACLs
by dovecot＠corwyn.net 03 Apr '09

03 Apr '09

Running Dovecot 1.1.8 using Virtual users, multiple domains. My file structure is /var/spool/mail/<domain>/<user>/Maildir/ (cur, new,tmp,.Spam) What I'd like to do is add an ACL such that all users can read/delete/move mail that's in the spam folder, but not delete it. Am I going to have to create an entry for every single user, or is there a way to do it once, for all .Spam folders? I've read through http://wiki.dovecot.org/ACL and can't quite get this as the last step. Thanks rick Rick Steeves http://www.sinister.net "The journey is the destination"

[Dovecot] Squat memory usage
by Ryan 02 Apr '09

02 Apr '09

I've been reading about using Squat with Dovecot on large mailboxes. I was wondering if some of the memory usage during searching and indexing could be reduced by using a berkeley db? I've used this in the past for something similar and in BTREE mode it was very fast for millions of keys. I havent had time to look at how squat is implemented, but I thought I'd throw it out there... -Ryan

[Dovecot] quota-fs: get nfs GROUP quota (patch)

[Dovecot] File and group permissions for incoming mails
by Sascha Scandella 02 Apr '09

02 Apr '09

Hello I am using Dovecot 1.1.1 together with Postfix (and for some users Procmail for Spam Filtering). Until now I didn't have to use shared mailboxes. Now I want to use simple simlinking to grant other users of the same group access to my mails. The problem is that new incoming mails have always file permissions set to 0600. I have also a file called dovecot-shared (0660) in the Maildir folder. No success. Why doesn't this work? I also tried to use UMASK in the procmailrc. No success. Any help is appreciated! Best regards Sascha

[Dovecot] dbox - how to awaken the monster
by Odhiambo Washington 02 Apr '09

02 Apr '09

Hello people, Since the invention of this storage called dbox, I have never quite gotten round to understanding it, nor getting to use it. It seems so strange to me and I must ask a few stupid questions about it. I use the MTA to deliver mail to Maildir, either in ~/Maildir or /some/path/%d/%n/Maildir. It has always beat me how dbox comes into play under such circumstances. From the wiki, I see the following: "dbox supports a quick migration from Maildir format" - now this leaves me hanging. How? Suppose I migrate from Maildir to dbox, what changes do I make to the MTA to understand that I use dbox? Ok, I use Exim as my MTA. I hope someone can explain to me what I need to do to Exim and what to do th Dovecot so that I can test this dbox thing. And suppose I want to transfer userA's mail to UserB, what do I do? With Maildir, I can simply do something like mv ~A/Maildir ~B/Maildir chown -R B ~b/Maildir Suppose I am using dbox, howdy? Thank you in advance. I know those sound dumb, but I simply haven't understood dbox. -- Best regards, Odhiambo WASHINGTON, Nairobi,KE +254733744121/+254722743223 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ "The only time a woman really succeeds in changing a man is when he is a baby." - Natalie Wood

[Dovecot] Dovecot in OSCON 2009?
by Timo Sirainen 02 Apr '09

02 Apr '09

Hi, I'm thinking about attending OSCON 2009 with some other people from Mailtrust and having some kind of an informal Dovecot meeting nearby. We could for example talk about what Dovecot would need to work better in your system, like missing features or if some things are annoyingly difficult etc, or just general talking and socializing. If you're interested in joining, send me a mail (privately, unless you have something else to say besides "yes").

[Dovecot] Slightly OT : Maildir format (silly) questions
by Thomas Hummel 02 Apr '09

02 Apr '09

Hello, I was asking what was the motivation for not having the envelope From in the Maildir format, as defined in the qmail spec : "The message is delivered without an extra UUCP- style From_ line, without any >From quoting, and without an extra blank line at the end." which may sound silly since we lose an important piece of information. Same question about the motivation in Courrier (Maildir++) for emulating a hierarchy for subfolders (like in .folder.subfolder.subsubfolder) instead of (note : I know about layout=FS, I'm not talking about that) implementing a real filesystem hierarchy. I understand dovecot kept those for compatibility reasons but I'd like to know what was the authors of thoses specs thinking when deciding this. Thanks -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

[Dovecot] Informations in LDAP and Database
by Etienne MAYNIER 02 Apr '09

02 Apr '09

Hi everybody, I'm installing an application using LDAP and I want dovecot to use LDAP too. The problem is that they don't use the same schema (especially because we want per-user quotas). I think the best solution is to have the authentication by LDAP and others datas (like quotas) in a database. Is it possible with dovecot ? and How ? Thanks Etienne

[Dovecot] postfix + dovecot

[Dovecot] courier-dovecot-migrate.pl issue
by Louis-David Mitterrand 02 Apr '09

02 Apr '09

Hi, I'm testing migration from courier to courier-0.57.0 to dovecot-imap-1.1.12 on a debian/sid box. When running the migration script, non of the active users' "courierimapsubscribed" and "courierimapuiddb" files seem to be detected: ZENON:~# ./courier-dovecot-migrate.pl --to-dovecot --recursive /home Testing conversion to Dovecot format Finding maildirs under /home /home/XXXX/Maildir: No imap/pop3 uidlist files /home/XXXX/CB: No imap/pop3 uidlist files /home/XXXX/Maildir/subscriptions already exists, not overwritten /home/XXXX/Maildir: No imap/pop3 uidlist files /home/XXXX/Maildir: No imap/pop3 uidlist files /home/XXXX/Mail: No imap/pop3 uidlist files /home/XXXX/Maildir: No imap/pop3 uidlist files /home/XXXX/Maildir: No imap/pop3 uidlist files Total: 0 mailboxes / 0 users 0 mailboxes / 0 users 0 errors No actual conversion done, use --convert parameter (the /home/XXXX users are old, non-active users) However when trying the courier-dovecot-migrate-1.0.pl I get plenty of mailbox matches, but since I am installing 1.1.12 it is useless to me. Dis I miss something? Thanks, -- http://www.critikart.net

[Dovecot] ampersand in local-part

[Dovecot] dbox with non-dovecot LDA
by Justin Krejci 01 Apr '09

01 Apr '09

Aside from the code is there any documentation on using dbox with a non-Dovecot LDA? We have our own MTA and currently use Dovecot with Maildir only for message retrieval and just have our MTA write the message files to our own directory structure (Dovecot per user mailbox locations stored in mysql) but I am interested in looking at moving to dbox if it is better for performance and other things like static filenames. One thing we'd like to do is not use the Dovecot LDA so as to control the entire inbound email delivery process all the way to verifying the actual message is 100% written to disk. Certainly we can use the Dovecot LDA if it came to it but we'd like to retain control over this entire process if possible.

[Dovecot] Virtual user folder configuration
by Daniel L. Miller 31 Mar '09

31 Mar '09

Since I'm going to make a change to my folder structure, what would be recommended so I can avoid the need in the future? All my mail users are virtual - they have no existence in /etc/passwd, nor do they have folders under /home. At this time, all mail is being delivered to maildir:/var/mail/%d/%n - and the home is the same (which is becoming more of a problem). As I see it, I have the choices of: 1. Place mail underneath home, as in /var/mail/%d/%n/mailbox Probably the simplest, but adds a level to the folder hierarchy. Does that matter in any way? 2. Place home underneath mail, as in /var/mail/%d/%n/home (unless THAT poses a problem as well, with a non-mail folder visible to the mail system) Leaves mail alone - but means the home folder is visible from within the mail system. 3. Relocate home totally outside mail, as in /var/mail/home/%d/%n Would provide isolation - but more difficulty in administration, particularly adding/deleting users. Any suggestions? -- Daniel

[Dovecot] CMUSieve with virtual users
by Guillaume HILT 31 Mar '09

31 Mar '09

Hi, I'm using dovecot 1.1.7 on Gentoo with Postfix and PostfixAdmin to manage my virtual users. I'm trying to use sieve (which has been compiled with Dovecot) but it doesn't work. I added cmusieve in the lda protocol : mail_plugins = cmusieve mail_plugin_dir = /usr/lib/dovecot/lda My maildir scheme is : /home/vmail/%d/%n/.maildir The sieve file is in /home/vmail/%d/%n/.dovecot.sieve (i'm using the sieve variable in the plugin section). I also tried in /home/vmail/%d/%n/.maildir/.dovecot.sieve. Then I tried in /var/sieve-scripts/%u.sieve. None of these solutions worked :x I enabled all the debug options in dovecot, and i can't see anything about sieve in my logs. I'm using the same configuration without virtual users on another server and it's working fine. I'm out of ideas. Could someone has managed to use sieve scripts with virtual users ? Thanks :) Guillaume

[Dovecot] Double mysql auth problem

[Dovecot] Sieve Rule for Folders
by Gerhard Wiesinger 31 Mar '09

31 Mar '09

Hello! Is it possible with sieve to do the following: When a new message is added to a folder (e.g. dovecot folder and not INBOX) then an action like forwarding it per E-Mail should be triggered. Is this possible? If yes, how does the sieve script look like? If possible, can a shell script also be triggered as action? Thanx. Ciao, Gerhard -- http://www.wiesinger.com/

[Dovecot] Empty To: Header and message_address_parse
by Wolfgang.Friebel＠desy.de 31 Mar '09

31 Mar '09

Using dovecot 1.2beta (but earlier versions should behave similarly) we have a problem in conjunction with empty To: headers and the RT request tracker. RT sends mail out using Bcc: and no To: header at all. To make some mailers happy one can configure to send a dummy To: header, which we do. Our To header looks like: To: "AdminCc of rt Ticket #123456":; The message_address_parse function called with the TRUE flag (triggers add_fixed_address) in dovecot changes that to To: AdminCc of rt Ticket #123456: MISSING_MAILBOX@MISSING_DOMAIN ; and then at least alpine does use that invalid address as Cc: address when replying. If the mail is stored in a local folder, i.e. does not get fetched via IMAP then the To: line is displayed as is and a reply does not result in an errorneous Cc: This behaviour is at least inconsistent from a user point of view. Is there some advice other than change the RT mail header generation? (other mailers seem to copy the To: line unaltered which results in an invalid address as well, therefore I admit that the real problem is with RT) -- Wolfgang Friebel Deutsches Elektronen-Synchrotron DESY Phone/Fax: +49 33762 77372/216 Platanenallee 6 Mail: Wolfgang.Friebel AT desy.de D-15738 Zeuthen Germany

[Dovecot] Convert from maildir to dbox
by Daniel L. Miller 31 Mar '09

31 Mar '09

Ok...I made the leap. Compiled a copy of 1.2b4 (very pleasant compile BTW - almost no warnings, nice code Timo!)...tweaked a config...had a few false starts... 1.2b4 seems to working quite nicely. Now...for my next magical trick... I would like to migrate from maildir to dbox. I've tried using the convert plugin, but it kept failing during the conversion. I should mention my paths: home (old & new) = /var/mail/%d/%n old mail = maildir:/var/mail/%d/%n new mail = dbox:/var/mail/%d/%n/dbox Note that "home" was defined as the same path as "mail" in my old config - I'm looking to fix that as well during the migration. I found entries in my mail log after the convert execution similar to: Mar 30 19:00:52 bubba dovecot: IMAP(sfox(a)amfes.com): rename(/var/mail/amfes.com/sfox/.dovecot.convert.lock/cur, /var/mail/amfes.com/sfox/dbox/mailboxes/dovecot/convert/lock/dbox-Mails) failed: Not a directory Mar 30 19:01:41 bubba dovecot: IMAP(sfox(a)amfes.com): Mailbox conversion failed for mailbox dovecot.convert.lock Now that I'm staring at that line...I'm wondering if that "home=mail" configuration is part of the problem. I currently have about a dozen users on this box - but with very large mailboxes (I still have archived mailing lists in mine!). If there's a few manual steps I need to perform to "condition" this setup prior to conversion please advise. Should I manually shift the mailboxes into a "/var/mail/%d/%n/maildir" folder? -- Daniel

[Dovecot] MAILBOXDIR question
by Stewart Dean 31 Mar '09

31 Mar '09

I'm unclear about where and how this is to be used. I gather it is to be a new standard, but I didn't seem to find anything about it in the Dovecot Wiki Mail Location page. There are some words about it in the 1.1.12/3 release notes, but perhaps I'm thick, but they're meta-ambiguous to me. Is it meant to be used like this: mail_location = mbox:MAILBOXDIR=~/mail:INBOX=/var/mail/%u instead of the current mail_location = mbox:~/mail:INBOX=/var/mail/%u ??? Sorry to be so dense. -- ==== Once upon a time, the Internet was a friendly, neighbors-helping-neighbors small town, and no one locked their doors.

[Dovecot] Panic: Trying to allocate 2147483648 bytes
by David Halik 30 Mar '09

30 Mar '09

Hi all, I recently upgraded from courier to dovecot 1.1.12 on a Solaris 9 system with about 100 users. We have been testing dovecot for sometime in a mixed Linux/Solaris environment and are aware of the index endianess issue with multiple archs. To solve this, we run with INDEX=MEMORY (as seen in the docs) so that only Linux clients have anything to do with the indexes. We generally have much more of them anyways. So far everything is working smoothly, but when someone does a search through directory with a large number of emails, dovecot dies and prints the following message: [ID 107833 mail.crit] Panic: Trying to allocate 2147483648 bytes I googled around and saw this same issue elsewhere, with NFS indexes usually being the problem. However, we have indexes turned off, so I don't understand why the same problem is still happening. Just to be sure, I ran with: mmap_disable = yes dotlock_use_excl = no mail_nfs_storage = yes But there has been no change, I can still reproduce it at will. Setting mail_nfs_index = yes caused my connections to stop working, so that didn't help either. Besides, I wouldn't think that would be the answer considering we set INDEX=MEMORY. This thread also seems to be related, but we're definitely running with this code in 1.1.12, yet it still happens: http://dovecot.org/list/dovecot/2008-September/033615.html I grabbed a backtrace if it is helpful: http://pastebin.com/f5f3d282c Also, here is dovecot -n: # 1.1.12: /usr/local/etc/dovecot.conf # OS: SunOS 5.9 sun4u protocols: imap imaps pop3 pop3s ssl_cert_file: /usr/local/ssl/certs/nbcs.key+crt.pem ssl_key_file: /usr/local/ssl/certs/nbcs.key+crt.pem login_dir: /usr/local/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 login_greeting_capability(default): yes login_greeting_capability(imap): yes login_greeting_capability(pop3): no mail_location: maildir:~/Maildir:INDEX=MEMORY mmap_disable: yes mail_nfs_storage: yes 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_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota pop3_quota 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): UID%u-%v namespace: type: private separator: . prefix: INBOX. inbox: yes list: yes subscriptions: yes auth default: passdb: driver: pam args: * userdb: driver: passwd plugin: quota: fs Any help would be appreciated!

[Dovecot] Upgrade from 1.0 to 1.1, plus migration from Maildir to dbox
by Daniel L. Miller 30 Mar '09

30 Mar '09

Ok - I gave up on trying to get CIFS to work - there's obviously stuff going on I don't understand. So - instead of trying to get a virtual server to work, I next tried a chroot. That worked...but imapsync error'ed out trying to handle one of my large mailboxes. I was trying to setup a "new" server, migrate all my mail over, verify everything worked - maybe even leave the virtual server operating for a while. But the fates are consipiring against me. So - time to make the leap. I want to upgrade a live version 1.0 server to version 1.1 (from Ubuntu repositories, using version 1.0.10 to 1.1.4). What special steps do I need to take to have this go smoothly? At least I have some semi-tested configs for 1.1 that I can use. Do I just stop the server, upgrade, upgrade the configs, start - and pray? Or is there another step? Also, my legacy installation was using maildir - I'd like to try shifting to dbox. Do I just need to change the prefix on mail_location and the conversion will magically happen? -- Daniel

[Dovecot] dovecot: auth(default): ldap(...): Authenticated user not found
by Stas SUSHKOV 29 Mar '09

29 Mar '09

Hi, I'm trying to set up dovecot together with postfix and experience some problems. Here's in details what I have and what I want to get. I have a ldap server on localhost, a working setup of dovecot to serve sasl, imap using ldap, a working setup of Postfix for (s)smtp (I can authenticate which uses dovecot's sasl). What i wan't to get is a completely working email server for ldap users with their email forwardings (so far they have only 1 forwarding). The porblem I stuck on is the following: when sending mail through (s)smtp, after passing authentication, I get my email dropped. And I see this in logs: http://ciorne.softwareliber.ro/index.php/view/raw/aaf3eb42 ***Authenticated user not found!!!*** My dovecot conf is this: http://ciorne.softwareliber.ro/index.php/view/raw/f8696531 And my dovecot-ldap is this: http://ciorne.softwareliber.ro/index.php/view/raw/698dc851 (I'm using prefetch) Can somebody point me where's my problem. *Any* advices are welcomed!!! Thank you in advance. P.S.: Environment is a vanilla installation of Ubuntu 8.04.02 with latest updates. -- () Campania Panglicii în ASCII /\ http://stas.nerd.ro/ascii/

Can dovecot do such things currently? (If not this is feature request). -- Arkadiusz Miśkiewicz PLD/Linux Team arekm / maven.pl http://ftp.pld-linux.org/

[Dovecot] Making changes to dovecot log levels
by Thomas M Goerger 27 Mar '09

27 Mar '09

Hi Timo, Not sure if you saw this yet, or if you're still working on a response. Awhile back I'd written about making changes to some of the log levels that dovecot writes to to stop the process from writing these to monitor. I wanted to run a few changes by you for this, just to make sure these won't cause problems somewhere else. And to send this to the list, in case anyone else wants to make similar changes in the future. In the file src/lib-index/mail-index.c: duplicate the function mail_index_set_error to mail_index_set_warning and call this function in /src/lib-index/mail_cache.c instead int mail_index_set_error(struct mail_index *index, const char *fmt, ...) { va_list va; i_free(index->error); if (fmt == NULL) index->error = NULL; else { va_start(va, fmt); index->error = i_strdup_vprintf(fmt, va); va_end(va); i_error("%s", index->error); } return -1; } changing the line : i_error("%s", index->error); to i_warning("%s", index_error); and for the file src/lib-storage/index/mbox/mbox-sync.c changing this code if (rec == NULL && uid < sync_ctx->idx_next_uid) { /* this UID was already in index and it was expunged */ mbox_sync_set_critical(sync_ctx, "mbox sync: Expunged message reappeared in mailbox %s " "(UID %u < %u, seq=%u, idx_msgs=%u)", sync_ctx->mbox->path, uid, sync_ctx->idx_next_uid, sync_ctx->seq, messages_count); ret = FALSE; rec = NULL; } else if (rec != NULL && rec->uid != uid) { /* new UID in the middle of the mailbox - shouldn't happen */ mbox_sync_set_critical(sync_ctx, "mbox sync: UID inserted in the middle of mailbox %s " "(%u > %u, seq=%u, idx_msgs=%u)",sync_ctx->mbox->path, rec->uid, uid, sync_ctx->seq, messages_count); ret = FALSE; rec = NULL; from mbox_sync_set_critical( etc... to mail_storage_clear_error(storage) i_warning("Error text"... mail_storage_set_internal_error(storage) to clear and set the storage pointer Hopefully that's all clear.

[Dovecot] outlook problem if TLS mailsettings are off

Behaviour: If I set /etc/dovecot/dovecot.conf: Following is valid with IMAP mailboxes only: disable_plaintext_auth = yes # outlook 2007 with TLS in/out enabled) can show index of mails and klick on mail does preview / doubleklick opens mail PERFECT AS INTENDED disable_plaintext_auth = no # outlook 2007 with TLS/SSL OFF can show index of mails, but (double)-/klick on mail gives me "sandwatch"-mouspointer and I've to restart outlook again (and enable TLS again to get it work again) with POP3 mailbox both variants are working smoothly.

Hi all, I have a dovecot installation which very suddenly decided to slow to a crawl yesterday after being totally fine for months. IMAP is fine, but POP3 is very painful to use, and frequently times out. here's my config: # 1.0.7: /etc/dovecot.conf log_path: /var/log/dovecot_errors info_log_path: /var/log/dovecot_informational ssl_ca_file: /etc/postfix/ssl/cacert.pem ssl_cert_file: /etc/postfix/ssl/postfix.webworks.ie.crt ssl_key_file: /etc/postfix/ssl/postfix.webworks.ie.key login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login login_process_per_connection: no login_processes_count: 6 first_valid_uid: 89 mail_location: maildir:/home/vmail/%d/%n mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: passdb: driver: pam passdb: driver: sql args: /etc/dovecot-mysql.conf userdb: driver: sql args: /etc/dovecot-mysql.conf I tried an strace as suggested by some other people. didn't know exactly what to attach it to, so did a "ps aux" (Centos 5.2, btw) and chose the first "pop3" process: [root@postfix cur]# strace -p 1697 Process 1697 attached - interrupt to quit gettimeofday({1238146840, 724484}, {0, 0}) = 0 gettimeofday({1238146840, 724542}, NULL) = 0 poll([{fd=4, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=2, events=POLLERR|POLLHUP|POLLNVAL}, {fd=0, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=1, events=POLLOUT|POLLERR|POLLHUP|POLLNVAL}], 4, 3123) = 0 gettimeofday({1238146843, 847540}, {0, 0}) = 0 gettimeofday({1238146843, 847590}, NULL) = 0 poll([{fd=4, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=2, events=POLLERR|POLLHUP|POLLNVAL}, {fd=0, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=1, events=POLLOUT|POLLERR|POLLHUP|POLLNVAL, revents=POLLOUT}], 4, 10000) = 1 gettimeofday({1238146847, 807077}, {0, 0}) = 0 write(1, "6DEDK02J5VXFQtloRQ/JPgdcCrSmSRXj"..., 2171) = 2171 setsockopt(1, SOL_TCP, TCP_CORK, [1], 4) = 0 pread64(9, "7P8JZloV9g/oYWdnm\nnZ9f+xzkO3fVXr"..., 4096, 102400) = 4096 write(1, "\r\nLhQoxZy+rq1TZXl2ZtrKrZH15dE2PK"..., 4134) = 3669 write(1, "uv69IdP6FDbO0lztPh2sA6Z/wBqIdP9Y"..., 465) = -1 EAGAIN (Resource temporarily unavailable) setsockopt(1, SOL_TCP, TCP_CORK, [0], 4) = 0 gettimeofday({1238146847, 807691}, NULL) = 0 poll([{fd=4, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=2, events=POLLERR|POLLHUP|POLLNVAL}, {fd=0, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=1, events=POLLOUT|POLLERR|POLLHUP|POLLNVAL}], 4, 6040) = 0 gettimeofday({1238146853, 847046}, {0, 0}) = 0 gettimeofday({1238146853, 847095}, NULL) = 0 poll([{fd=4, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=2, events=POLLERR|POLLHUP|POLLNVAL}, {fd=0, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=1, events=POLLOUT|POLLERR|POLLHUP|POLLNVAL, revents=POLLOUT}], 4, 10000) = 1 gettimeofday({1238146856, 546780}, {0, 0}) = 0 write(1, "uv69IdP6FDbO0lztPh2sA6Z/wBqIdP9Y"..., 465) = 465 setsockopt(1, SOL_TCP, TCP_CORK, [1], 4) = 0 pread64(9, "24\nekSIYgeKr5kpQwrk4iWMqC2+/uvwf"..., 4096, 106496) = 4096 write(1, "\r\nIHaoJDSPFqr4jw9SP8S2yLsWOt2RVx"..., 4134) = 4134 pread64(9, "DUJvKTRdVNxs3JTdRQYqD61EYbg22DLb"..., 4096, 110592) = 4096 write(1, "\r\nbDlx3+0LszvjOrD5+04T8PF39frFpQ"..., 4134) = 1241 write(1, "9Zc/wAr\r\nF1bI22U8dNTIKBc423KFJSO"..., 2893) = -1 EAGAIN (Resource temporarily unavailable) setsockopt(1, SOL_TCP, TCP_CORK, [0], 4) = 0 gettimeofday({1238146856, 547406}, NULL) = 0 poll( <unfinished ...> Process 1697 detached looking forward to you all saving my sanity! thanks, kae

[Dovecot] Preventing IMAP folder deletion?
by dovecot＠corwyn.net 27 Mar '09

27 Mar '09

Hi! I'm running postfix with dovecot using mysql for user accounts, with Outlook being used as the IMAP mail client. I'm using a mail delimiter ("+") and mail automatically goes to a Spam folder as part of spam filtering with amavisd and spam assassin. It's configured so that folders won't automatically create; if the folder isn't there mail delivers to the inbox (so that spam doesn't create extra folders). the problem I ran into today is that a user deleted the Spam folder. While recreating it isn't that hard, is there a way I can prevent them from being able to delete specific folders in IMAP? In squirrelmail I can create "system" folders that the user can't change or delete, but that's client based. Since I don't see that ability in Outlook, can I somehow configure dovecot so the user can't delete specified folders? Thanks Rick Rick Steeves http://www.sinister.net "The journey is the destination"

[Dovecot] Version 2.0 with multiple IP/TLS certificate support.
by Gordon Dickens 26 Mar '09

26 Mar '09

Hello, I sent this email earlier but for some reason it did not go through so I will try again! I am using Dovecot on several servers that require multiple domain SSL certificates. I like Dovecot very much because of its speed and stability. Currently, Dovecot does not support multiple SSL certificates directly although I have gotten around this problem with multiple Dovecot instances running multiple configuration files. However, I would prefer to have one configuration file that supports multiple domain certificates. My understanding is that Dovecot Version 2.0 will have this "multiple SSL certificate" feature. So, my question is, when is version 2.0 projected to be released? Many thanks! Gordon Dickens

[Dovecot] v1.2.beta4 released
by Timo Sirainen 26 Mar '09

26 Mar '09

http://dovecot.org/releases/1.2/beta/dovecot-1.2.beta4.tar.gz http://dovecot.org/releases/1.2/beta/dovecot-1.2.beta4.tar.gz.sig This release fixes a memory corruption bug related to MODSEQ handling in earlier v1.2 releases. Memory corruption means that it's a security bug and possibly exploitable. MODSEQ code is new in v1.2, so v1.1 and older releases are not affected. Other than that, there is an ESORT bugfix and other fixes that were added to v1.1 branch too.

[Dovecot] Missing TMP folder - Dovecot 1.2 Beta3
by Matt Rude 26 Mar '09

26 Mar '09

Recently after upgrading to 1.2 Beta3 from 1.1.13, I started to defer mail. After looking into it deeper, it looks like Dovecot/sieve now asks for a tmp folder in the imap (maildir) folder. Once I added the tmp folder as the logs indicants, the mail was processed normally. I have split my Inbox and imap store to different folder. Looking at what it's trying to do, it looks to me that dovecot/sieve expect the imap directory to be the Inbox. Is this a bug, or intended behaver? # Log output, when requeueing the message in postfix, with mail_debug on ######################################################################### Mar 24 12:02:50 samantha postfix/qmgr[6855]: EB4141237BD: from=<colleen(a)example.com>, size=493284, nrcpt=1 (queue active) Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): Loading modules from directory: /usr/local/lib/dovecot/lda Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): Module loaded: /usr/local/lib/dovecot/lda/lib10_quota_plugin.so Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): Module loaded: /usr/local/lib/dovecot/lda/lib20_expire_plugin.so Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): Module loaded: /usr/local/lib/dovecot/lda/lib90_cmusieve_plugin.so Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): auth input: maildir=example.com/jill@example.com/ Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): auth input: uid=1000 Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): auth input: gid=1000 Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): auth input: quota_rule=*:storage=524288 Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): Quota root: name=User quota backend=maildir args= Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): Quota rule: root=User quota mailbox=* bytes=536870912 messages=0 Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): Quota rule: root=User quota mailbox=Trash bytes=53687091 (10%) messages=0 Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): Quota rule: root=User quota mailbox=Junk bytes=107374182 (20%) messages=0 Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): maildir: data=/var/spool/virtualmailboxes/example.com/jill@example.com/imap/:INBOX=/… Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): maildir++: root=/var/spool/virtualmailboxes/example.com/jill@example.com/imap, index=/var/spool/virtualmailboxes/Indexes/example.com/jill@example.com, control=, inbox=/var/spool/virtualmailboxes/example.com/jill@example.com Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): cmusieve: /var/spool/virtualmailboxes/example.com/jill(a)example.com/dovecot.sieve doesn't exist Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): cmusieve: Using sieve path: /var/spool/sieve/dovecot.sieve Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): cmusieve: Executing script /var/spool/sieve/dovecot.sievec Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): Namespace : Using permissions from /var/spool/virtualmailboxes/example.com/jill(a)example.com/imap: mode=0700 gid=-1 ****** Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): creat(/var/spool/virtualmailboxes/example.com/jill@example.com/imap/tmp/tem… failed: No such file or directory ****** Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): copy: i_stream_read() failed: No such file or directory Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): msgid=<85866319ca18bf9cd994e34fe806c4f5.squirrel(a)mail.mattrude.com>: save failed to INBOX: Internal error occurred.

[Dovecot] Dbox Upgrade Problem With MAILBOXDIR

25 Mar '09

Hi. Trying to upgrade from Dovecot 1.1.11 to 1.1.13 but having a problem with imap process segfaulting. Backtrace is below.

[Dovecot] selection correct auth with multiple auth methods
by jm 25 Mar '09

25 Mar '09

How do you control which socket or authentication process dovecot's pop3 daemon chooses to use? I've got a user database with two flags one to allow pop3 access and the other to allow the use of auth smtp. There are two authentication instances configed, thus, auth default { .... passdb sql { args = /etc/dovecot-sql-postfix.conf } .... socket listen { master { path = /var/run/dovecot/auth-master mode = 0660 user = group = } } auth postfix { ..... passdb sql { args = /etc/dovecot-sql-postfix.conf } .... socket listen { client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } } From the logs and testing pop3 is using the postfix authentication instance and not the default as expected. Does anyone out there know how control dovecot's pops daemon authentication choice? This infomation seems to be lacking in the documentation I can find. Jeff.

[Dovecot] Making changes to dovecot log levels
by Thomas M Goerger 24 Mar '09

24 Mar '09

Hi Timo, Awhile back I'd written about making changes to some of the log levels that dovecot writes to to stop the process from writing these to monitor. I wanted to run a few changes by you for this, just to make sure these won't cause problems somewhere else. And to send this to the list, in case anyone else wants to make similar changes in the future. In the file src/lib-index/mail-index.c: duplicate the function mail_index_set_error to mail_index_set_warning and call this function in /src/lib-index/mail_cache.c instead int mail_index_set_error(struct mail_index *index, const char *fmt, ...) { va_list va; i_free(index->error); if (fmt == NULL) index->error = NULL; else { va_start(va, fmt); index->error = i_strdup_vprintf(fmt, va); va_end(va); i_error("%s", index->error); } return -1; } changing the line : i_error("%s", index->error); to i_warning("%s", index_error); and for the file src/lib-storage/index/mbox/mbox-sync.c changing this code if (rec == NULL && uid < sync_ctx->idx_next_uid) { /* this UID was already in index and it was expunged */ mbox_sync_set_critical(sync_ctx, "mbox sync: Expunged message reappeared in mailbox %s " "(UID %u < %u, seq=%u, idx_msgs=%u)", sync_ctx->mbox->path, uid, sync_ctx->idx_next_uid, sync_ctx->seq, messages_count); ret = FALSE; rec = NULL; } else if (rec != NULL && rec->uid != uid) { /* new UID in the middle of the mailbox - shouldn't happen */ mbox_sync_set_critical(sync_ctx, "mbox sync: UID inserted in the middle of mailbox %s " "(%u > %u, seq=%u, idx_msgs=%u)",sync_ctx->mbox->path, rec->uid, uid, sync_ctx->seq, messages_count); ret = FALSE; rec = NULL; from mbox_sync_set_critical( etc... to mail_storage_clear_error(storage) i_warning("Error text"... mail_storage_set_internal_error(storage) to clear and set the storage pointer Hopefully that's all clear.

[Dovecot] Problem with dovecot + imap idle + qmail-local delivery
by Jochen Schug 24 Mar '09

24 Mar '09

Hi, I've recently switched from courier-imap to dovecot. Everything seemed to work fine, but after I while I noticed that dovecot is occasionaly causing problems with delivery of new incoming mails. System: Gentoo Linux, kernel 2.6.19, qmail 1.03, vpopmail 5.4.26 , dovecot 1.1.11, maildir, mail store on ext3. Symptoms: qmail is having trouble with the mail delivery. First I thought it had something to do with vpopmail or dovecot's quota support, but I tracked it down to qmail-local. I tried two different versions, one with Bill Shupp's maildir++ patch and one without. With the patch, I'm getting "User_over_quota._(#5.1.1)" errors. Mail is delivered once and sender is sent a notification about the exceeded quota. Without the patch, I get "Temporary_error_on_maildir_delivery._(#4.3.0)". Mail is delivered, but delivery is tried again and again. This only happens if a MUA is logged in to the mailbox and IMAP IDLE is being used. If the MUA is disconnected: fine. If dovecot is stopped: fine. I tried a couple of different things, all without success: - upgraded dovecot from 1.1.7 to 1.1.11 - compiled a new kernel with inotify support and recompiled dovecot - migrated mail store from reiserfs to ext3 - disabling quota support in dovecot - tried dovecot's various file locking mechanisms Right now I'm working around this by removing IDLE from the capabilities. This solves the problem, but leaves me with a less functional IMAP server. Any help is greatly appreciated.

[Dovecot] Staged migration from mbox to maildir
by Stewart Dean 24 Mar '09

24 Mar '09

So much changes in this migration that the ideal way to do it would be to begin with a few users or a department, then migrate the users affinity group by affinity group: first an institute or so, then the faculty, then the staff, then the students, moving to bigger and bigger groupings as the bugs work out of the migration and the move becomes more assured. We use sendmail and procmail. There's no problem there, as the ~./procmailrc can be changed to over-ride the mbox default until all groups are done and it become the default. The problem comes with IMAP. While dovecot can tell if a folder is mbox or maildir, it has to be pointed to the right place (by namespace definitions in the client, IIRC), and the default of putting the inbox under ~/mail is one I'd like to embrace for various reason...but given that that means moved inbox folders and *that* means either making a global change (there goes staged migration) OR changing the namespace definitions on each PC. I can get to the early few and change the namespaces definition, but there doesn't appear to any equivalent (enlighten me, if I'm missing something) to ~/.procmailrc for imap, so that I don't have to get on the client machine. Is this correct or am I (hopefully) wrong and there *is* a way to change things on the server that allows for staged migration? Oh, I would so like to be wrong!

[Dovecot] Released Sieve v0.1.4
by Stephan Bosch 23 Mar '09

23 Mar '09

Hello Dovecot users, Not much Sieve development was done in the last five weeks, but some important platform-dependent bugs were found and repaired. The main new feature is the addition of a custom Sieve language extension for debugging in the Sieve command line tools. Changelog Sieve v0.1.4: * Started work on the sieve-filter tool. With this command line tool it will be possible to (re-)apply Sieve filters on a mail folder. It is currently undocumented and far from functional. + Added a custom debug extension that provides the possibility to print debug messages from scripts executed by the Sieve tools. - Fixed issue with opening relative paths as a mail file. Bug reported by Ian P. Christian. - Fixed MAC OSX compile problem. Turns out the extern modifier was missing at multiple places. Bug reported by Edgar Fuss. - Fixed Solaris compile problem: removed unecessary and unportable linker flags that caused compile to fail. Bug reported by Andres Yacopino. The release is available as follows: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.4.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.4.tar.gz.sig Have fun testing the new release and don't hesitate to notify me when there are problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

[Dovecot] Single Instance Storage still on the roadmap?

Hey Timo, I was curious where Single Instance Storage fits in on the roadmap, now that you are maybe settled in in your new digs... Is it still coming soon? Has it been pushed back by your new employers priorities? Its real high on mine, so if has been back-burnered, I'll need to start looking for alternatives... Thanks, -- Best regards, Charles

[Dovecot] update of current quota usage
by floss＠pBartels.info 20 Mar '09

20 Mar '09

Hello, I use Dovecot 1.1.11 and store the current quota usage in a Database. As far I can see it, the quota usage is updated each time dovecot performs an action on a mail. For example if a new mail is stored in the inbox, the current quota usage is increased. If a mail is deleted the quota usage is decreased. If there are still existing E-Mails in the inbox, before quota is turned on or if I perfom changes on the "mail storage" myself (for example purging trash or spam, or something) the current quota usage is NOT updated automatically by dovecot. For example I copy some mailboxes to my server, then the current quota for this mailboxes is still zero. Is it correct that dovecot can't do this for me? If yes, it seems I have to write my own (simple) update script and run it sometimes croned (because I don't really trust the actual quota implementation) and/or I have to update the current quota usage each time I perform actions myself. This "workaround" is easy by using a DB storage, but what about other implementations? Wouldn't it be nice if dovecot could do this or provide a tool for it? Thank you! Philipp

[Dovecot] IMAP ACLs not working

Hi, I've some problems to get folder ACLs working with Dovecot.

[Dovecot] mbox on NFS + automount, folder creation -> mkdir_parents() failed
by Sebastian Kayser 18 Mar '09

18 Mar '09

Hi, i am about to migrate some internal imapd mboxes to dovecot. Regular access is fine, just when i want to create a folder i get the following error message in the logs: Mar 18 17:36:57 pulsar dovecot: [ID 107833 mail.error] IMAP(skayser): mkdir_parents(/home/skayser) failed: Operation not applicable /home/skayser is mounted via autofs. When i set mail_location to a subdirectory within /home/skayser, folder creation works. From looking at the truss output dovecot tries to mkdir() the parent and doesn't seem to like the ENOSYS that is returned when the directoy is an autofs mountpoint.

[Dovecot] NFS-error with dovecot 1.1.12
by Martin Preen 18 Mar '09

18 Mar '09

Hello, I'm testing version 1.1.12 and occasionally there is Mar 18 14:40:44 imap2 dovecot: [ID 107833 mail.error] IMAP(xyz): nfs_flush_file_handle_cache_dir: rmdir(/home/xyz) failed: Device busy It seems that it is related to a crash of the previous imap process of that user. And it doesn't seem to cause any problems. So can it safely be ignored ? It is on Solaris 10. Index storage is local (UFS) and mailbox storage is NFS (mail_nfs_storage=yes).

Uhg, I win the CluelessnUnobservant Award for this. Thanks everyone for the followups. I caught that myself yesterday and fixed the problem on Postfix's side. To sum up in case anyone else runs in to this, the mistake I made was in assuming that Postfix just made the handoff to Dovecot and that Dovecot would handle the rest, so I commented out the parts of the old config where Postfix handled this when I was using Postfix virtual transport. Once I restored those and gave Postfix the query it needed, it worked fine. Thanks for bearing with me, everyone. Kat

Delivering works well, I'm just not sure if everyone could revive the emails ? Any tips ? reagards, Sebastian

Timo wrote: > So Postfix delivers bounces to everyone by calling Dovecot LDA > separately for each bounce? Looks like a Postfix configuration problem > to me. I should have been more specific... because we'd also changed domain names at the time we moved over to using Dovecot as the LDA, I temporarily disabled automatically bouncing mail addressed to invalid users because I figured that we'd have at least one who decided that they didn't want the standard formation of email addresses... What I'd wanted to happen was for Postfix to accept the message(s) and then for them to be delivered to the postmaster address so that I could address the issue. I'm still unsure as to why, when Dovecot couldn't find the user in the tables, it copied the message to every user of the system - that seems like odd behavior, which indicates that even though the system is "working", I need to fine-tune something.

[Dovecot] ACLs are applied recursively to sub mailboxes

[Dovecot] Dovecot as a POP3-/POP3SSL-proxy in front of exchange 2003
by south africa 17 Mar '09

17 Mar '09

Dear all, im looking for a solution to protect an Exchange 2003 email server from direct "pop3-internet-connects". Is it possible that Dovecot act as a POP3-/POP3SSL-Proxy, "LDAP-authenticate" all user logins to a Windows 2003 domain controller and forward then all POP3-connects to a single Exchange 2003 server? Could someone give me some advices or a link for howtos for this solution? The howto on www.dovcot.org (http://wiki.dovecot.org/HowTo/ImapProxy) does not fit in my situation because it prefere a mysql server and not a LDAP-server/domain-controller.

I have Julian Fitzell's migrateuser.sh script which uses mb2md-3.20.pl to convert a mailbox in mbox format to Maildir. I have set up a test user called "mailtest" which has mail as follows: /var/mail/mailtest /home/mailtest/mail/ Drafts MoreStuff Sent Items Stuff After the conversion I want all this user's mail to be in /home/mailtest/Maildir/ I'm not quite sure how to run the migrateuser.sh script, but I think it's like this (run as user mailtest): $ /usr/local/bin/mb2md/migrateuser.sh mailtest /home/mailtest /home/mailtest/Maildir When I run this I get the following output: mailtest -- Migrating INBOX...

hi guys, I hope it's common trouble, but I'm not able to find a solution: - i'am using courier imap and trying to migrate to the dovecot - on courier I have all folders as subfolder of Inbox - i.e. Inbox.Sent but on dovecot the folder Sent is not subfolder of Inbox, but its on the same level. Please is there some possibility to have the subfolders the same behaviour as in courier? we have lot's of customers so after the upgrade the folders can't change. thank you ondrej

[Dovecot] Dovecot and high availability
by d dimov 16 Mar '09

16 Mar '09

Hello dear all. Please accept apologies if the topic was discussed already, tried searching the archives but found few details. What I am looking for would be the best way to making Dovecot highly available in an environment where: two Alteons are load-balancing two Dovecot servers, each Alteon seing both of them; the clients are using exclusively POP3; low volume; in case of a Dovecot server failure service should fail over to the other node with preferably no manual intervention. Failover could mean Alteons just ignoring the failed host and routing all requests to the healthy one. Would it be shared NFS volume mounted on both of the servers from some NAS, maildirs put on that volume and both Dovecots seing the mailboxes simultaneously? Any risks? Is there a good document describing such a setup? Thank you in advance and please indicate if I missed relevant details. Best regards, Dimov

[Dovecot] Mailing list convert scripts not working on wiki

I'm trying to download Julian Fitzell's scripts to convert mbox to Maildir format from the wiki page at http://wiki.dovecot.org/Migration/MailFormat But when I click on the links for the scripts it just sends me back to the same page rather than downloading the scripts. The links in question are http://wiki.dovecot.org/Migration/MailFormat?action=AttachFile&do=get&targe… and http://wiki.dovecot.org/Migration/MailFormat?action=AttachFile&do=get&targe… How can I get the scripts?

Previously with pop3_lock_session = yes, I needed mail_access_group = mail. With the upgrade to beta2, I changed that to mail_privileged_group = mail as shown above. Now, during a session lasting several seconds, I see the following in maillog: Mar 15 09:35:51 sbh16 dovecot: pop3-login: Login: user=<mark>, method=APOP, rip=68.183.193.239, lip=72.52.113.16, TLS Mar 15 09:36:01 sbh16 dovecot: POP3(mark): fstat(mark.lock) failed: Bad file descriptor Mar 15 09:36:04 sbh16 dovecot: POP3(mark): Disconnected: Logged out top=0/0, retr=1/1919972, del=0/328, size=5381253 Mar 15 09:36:04 sbh16 dovecot: child 9023 (pop3) killed with signal 11 (core dumps disabled) This does not occur with shorter sessions lasting only a few seconds or less. The only symptom is the log messages. The client sees nothing unusual, at least in this case where the session is a retrieval of one large message. I haven't tried long sessions retrieving multiple messages. If I remove pop3_lock_session = yes, the issue does not occur. I don't think I need it. I put it in a long time ago to attempt to solve a problem that was actually caused by something else. Since removing it does seem to avoid this issue, I will leave it out, but I'm reporting this anyway as it seems there may be some underlying problem. -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.

[Dovecot] pop-proxy to redundant servers ?
by Jan-Frode Myklebust 15 Mar '09

15 Mar '09

I'm considering putting two servers with failover IP-addresses in front of our pop/imap cluster, with dovecot in proxy-mode running on both servers. But, can dovecot handle more than one backend server for each user ? I.e. I would want to point the dovecot proxy to send userX to backend-server1, or backend-server2 if backend-server1 is down. Is something like that possible ? -jf

Changes in v1.2.beta2 since beta1: * Authentication userdb: Renamed system_user to system_groups_user. Probably pretty much no one used this feature. * deliver no longer creates temp files to /tmp. They're instead created to the users' mailbox directories. - IMAP: Fixed SORT command crashing - POP3 was broken in beta1 - Fixes to virtual mailboxes - Fixes to IMAP ACL support Changes in both v1.1.12 and v1.2.beta2: * Added :MAILBOXDIR= to mail_location to specify the root dir for mailboxes. dbox users should migrate to ":MAILBOXDIR=mailboxes", because that's going to be the default in v1.2+. + Linux: Adding -D parameter to login_executable makes login processes dump core to login_dir if they crash. - IMAP: SELECT didn't always return first unseen message in reply - POP3: pop3_lock_session=yes didn't use mail_privileged_group while dotlocking. - mbox: Don't crash if >=8192 bytes long line begins with "From ". - Maildir: More fixes to handling over 26 keywords. - Several logging fixes and improvements - Fixed authentication caching with non-plaintext mechanisms when using a blocking passdb (e.g. MySQL) - Fixed DIGEST-MD5 authentication with user@domain style usernames.

[Dovecot] setting up both system password users AND virtual users
by Jim Pazarena 14 Mar '09

14 Mar '09

I'm afraid that I am a rookie at dovecot, and cannot seem to figure the configuration for a dual system & virtual setup. For now I am using POP3 ---only--- I've got the "system" working, but cannot figure out how to add the virtual system. The docs aren't quite clear enough for me to understand. The wiki example for dynamic passwd-file locations shows: mail_location = maildir:/home/%d/%n/Maildir userdb passwd-file etc etc I am using mbox, not maildir, AND I've already used mail_location for my system accounts with the following line: mail_location = mbox:~/mail/:INBOX=/mail/%u In the case of my virtual users, the mail is stored in INBOX=/mail/VIRTUAL/%d/%u and the password file is stored in /exim/etc/VIRTUAL/%d/passwd would someone kindly help me with this? thanks!

If so, I think the behavior is correct. Maybe change the query to: where username = '%n' and (domain = '%d' or ('%d' = '' and domain is null)) And change all the domain='' to domain=NULL.

[Dovecot] New to list, got a quota question
by Vlad Sedov 14 Mar '09

14 Mar '09

Hello folks - I'm running dovecot on top of qmail/vpopmail/mysql, serving up about 2500 mailboxes. Everything is running very smooth and fast.... I recently upgraded dovecot to 1.1, so I'm trying to implement some extra features like IMAP quotas. I'm using the sql passdb, with the following config: driver = mysql connect = host=/var/lib/mysql/mysql.sock user=username password=password dbname=vpopmail default_pass_scheme = PLAIN password_query = SELECT CONCAT(pw_name, '@', pw_domain) AS user, pw_clear_passwd AS password FROM vpopmail WHERE pw_name = '%n' AND pw_domain = '%d' user_query = SELECT pw_dir as home, 508 AS uid, 503 AS gid FROM vpopmail WHERE pw_name = '%n' AND pw_domain = '%d' My vpopmail installation keeps the quota information in the mysql database (pw_shell field) instead of maildirsize. The quota is in maildir format, e.g. 400M or 50331648S. Unlimited quota is specified as NOQUOTA. The question is... Is it possible to make dovecot understand this format and get it directly from SQL (via user_query, for example) or would it be easier to reconfigure the vpopmail installation somehow to use maildirsize? Thanks! Vlad

[Dovecot] how to handle CA CRL updates with client certificate verification context ?
by Raphael PRECIGOUT 13 Mar '09

13 Mar '09

Hello, As far as I can read in the Dovecot SSL configuration wiki page, each CA cert must be followed by the related CA CRL in the client certificate verification context ("ssl_ca_file" setting). In my company we do have our own PKI and as soon as Client certificate is compromised we do revoke it and update the related CA's CRL. Does that mean that I have to issue a new "ssl_ca_file" file as soon as our issuing CA CRL is updated ? If yes, does someone has an idea on how to do so ? Is it then necessary to restart dovecot process (to take the "ssl_ca_file" file changes into account) ? Does Dovecot have a way to check the issuing CA CRL automatically ? (the CRL is published in DER format and is accessible though http, the URI is mentionned in the CRL Distribution points of the CA certificate) Thanks in advance for your help. Regards, Raphael

[Dovecot] Problem with sasl auth with postfix...
by Douglas M. Stanley 13 Mar '09

13 Mar '09

Hello list, I'm running into some problems, and I couldn't find any info about this anywhere on the net. I recently set up a new debian lenny machine, and used my notes from the last debian etch machine I set up, which basically is for postfix + dovecot for sasl auth. On my old etch box, in the dovecot.conf, in the auth default section, I have a socket listen { client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } However, if I use the same config on my lenny setup, dovecot fails to start, and I see this in my logs: Mar 13 19:16:30 mailserver dovecot: Dovecot v1.0.15 starting up Mar 13 19:16:30 mailserver dovecot: auth(default): User doesn't exist: postfix Mar 13 19:16:30 mailserver dovecot: Auth process died too early - shutting down Mar 13 19:16:30 mailserver dovecot: child 4623 (auth) returned error 89 Now if I comment out the user and group lines, it works fine, but the socket is owned by root, and so I have to change the mode line so that it's world readable in order for postfix to use it. The version of dovecot in etch is: 1.0.rc15-2etch4 and the version in lenny is: 1.0.15-2.3 Any ideas why this might be happening? Did the syntax to do this change between those versions? Any input? I guess I don't mind leaving it world readable, but I wasted an entire morning trying everything to get it to work, so I guess I'm hoping some one atleast has an answer as to why it doesn't work. Thanks, Doug

[Dovecot] Using LDAP for Dovecot extra/regular fields
by Jack Stewart 13 Mar '09

13 Mar '09

Hi, We're moving to a dovecot proxy / server configuration in order to make sure that a users go to a specific server. If someone has used these LDAP for this, there are a few things that I wish to verify. Dovecot does not verify that type of the LDAP attribute, only that the returned value works. If a boolean is used for a yes/no field, then FALSE sets the field to no and TRUE sets the field to yes. If a multivalue attribute is used for a single value field, the last returned value for the LDAP lookup is used in that field (i.e. host will use the last value). If a string attribute is returned for a yes/no field and has any value, then the associated field is set to true. There is no automatic failover with the host field so if the remote host is down, the IMAP connection no longer works. I'm fairly sure of all of these except for the boolean. Now this is just due diligence. I don't know that turning on/off or switching LDAP attributes is the right way to go to handle failover but it might work for phased rollout. My feeling is the best configuration will be using a secondary IP address that has to be manually turned on for a host after a reboot or shutdown. This creates a poor mans "fencing". The secondary can either be brought up on another host or handled via a load balance with DSR/backup server. As a practical matter, it is probably worth setting sensible attributes for each field (i.e. numeric for host, boolean for proxy/proxy_maybe etc). Any interest in registering an LDAP object class for dovecot? ---Jack

[Dovecot] Maildir dirty syncs
by Timo Sirainen 13 Mar '09

13 Mar '09

http://dovecot.org/patches/1.1/maildir-dirty-syncs.diff This patch adds a new maildir_very_dirty_syncs setting. If set to "yes", Dovecot assumes it's the only one changing the cur/ directory (so other MDAs can add mails to new/ without problems). This makes it possible to avoid rescanning the cur/ directory all the time looking for filenames. It also looks like (in stress testing) it still scans the cur/ directory unneededly in some situations, but it shouldn't be common. Maybe I'll look into it some day to see why. I'd be interested in hearing how large performance benefits it gives, if any. If they're big I could consider adding it to v1.1.12. If they're pretty much irrelevant I probably won't even bother adding the code to v1.2. I guess you mainly see the performance benefits with large/huge mailboxes.

[Dovecot] General approach question - am I doing this the right way?
by Alan Bates 13 Mar '09

13 Mar '09

Quick outline of my current working setup: I'm running dovecot 1.0.5 as an IMAP mail server on my ubuntu home server, which i connect to with my phone and several other machines to check my mail etc. i use getmail to collect mail from my various pop accounts. getmail filters the mail using spamassassin via a Filter_external, before moving it to my Maildir on the home server. Then when I connect to the home server from my various machines, IMAP manages the status of all the mail, so unread messages are common etc. All works very nicely. However I'd like to fix a minor annoyance... ...Spamassassin marks mail as SPAM but the mail client has to do the job of moving it to the Junk folder. I'd like the mail to be filtered on the home server on receipt. Am I just making things really complicated for myself? Is there a simpler setup for what I'm trying to do? Thanks in advance for any thoughts or suggestions

[Dovecot] Extremely custom mailbox locations
by Steve Kemp 13 Mar '09

13 Mar '09

I'm in the position where I'd like to offer IMAP access to a collection of email accounts which are stored in a very odd manner. Files are stored as: /blah/$dd-$mm-$yy/$domain/1234/1234 For example: /reject/12-3-2009/cvsrepository.org/35199/35199639 There is a single file for each mail, which I guess technically probably counts as an mbox folder, but only just. I can handle the custom login requirements I have, but I see no obvious way to create a mailstore from this information unless I build up a parallel symlink farm, such as: /imap/cvsrepository.org/{new cur tmp} I suspect if I fill cur/ with symlinks to each of the individual messages things will mostly work out OK, but I wonder if that is the best solution, or if there is a slim chance that I could serve this hierarchy without the intermediate step?

[Dovecot] which architecture to use?
by GVG GVG 13 Mar '09

13 Mar '09

Dear List, Based on the following installed environment: - OpenBSD (latest version!) - PostgreSQL - dovecot with SSL would like to have a mail server which accepts system as well as virtual users and being able to connect to their mailboxes either via an MUA (Thunderbird etc.) or a web interface (squirrel mail?). When using the web interface, non registered users should be able to creat e-mail accounts which will be dovecot virtual users! Which components should I use? Thanks

Hello, It's my first mailserver I set up. Thanks to everybody who contributes to dovecot. Dovecot works great for me! One thing I want to get rid off is this traceback error using dovecot with sieve. Somebody can help on this? System: Ubuntu server 8.10 dovecot --version 1.1.4 I filter for keywords in mail body with sieve. Mail is stored at lokal harddrive. I already deleted dovecot.index.cache - no success. Here is what logs say: sudo dovecot -n # 1.1.4: /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login mail_privileged_group: mail mail_location: maildir:~/Maildir auth default: mechanisms: plain login passdb: driver: pam userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/auth-client mode: 432 user: postfix group: postfix /var/syslog Mar 10 22:19:01 aquarius /USR/SBIN/CRON[23838]: (root) CMD (/etc/webmin/fetchmail/check.pl --owner --errors) Mar 10 22:19:04 aquarius deliver(brabax): Panic: file sieve-cmu.c: line 264 (part_save): assertion failed: (buf->used - 1 == part- >body_size.physical_size) Mar 10 22:19:04 aquarius deliver(brabax): Raw backtrace: /usr/lib/dovecot/deliver [0xb8068e01] -> /usr/lib/dovecot/deliver(i_syslog_fatal_handler+0x38) [0xb8068ee8] -> /usr/lib/dovecot/deliver [0xb8068695] -> /usr/lib/dovecot/modules/lda/lib90_cmusieve_plugin.so [0xb7e394b6] -> /usr/lib/dovecot/modules/lda/lib90_cmusieve_plugin.so [0xb7e3ac24] -> /usr/lib/dovecot/modules/lda/lib90_cmusieve_plugin.so [0xb7e43b34] -> /usr/lib/dovecot/modules/lda/lib90_cmusieve_plugin.so [0xb7e43e13] -> /usr/lib/dovecot/modules/lda/lib90_cmusieve_plugin.so(sieve_eval_bc+0x47e) [0xb7e4533e] -> /usr/lib/dovecot/modules/lda/lib90_cmusieve_plugin.so(sieve_execute_bytecode+0x125) [0xb7e4b4d5] -> /usr/lib/dovecot/modules/lda/lib90_cmusieve_plugin.so(cmu_sieve_run+0x325) [0xb7e3a785] -> /usr/lib/dovecot/modules/lda/lib90_cmusieve_plugin.so [0xb7e38456] -> /usr/lib/dovecot/deliver(main+0x1229) [0xb7ff2c39] -> /lib/tls/i686/cmov/libc.so.6(__libc_start_main+0xe5) [0xb7e6b685] -> /usr/lib/dovecot/deliver [0xb7ff0531]

[Dovecot] 1.1.12 release candidate
by Timo Sirainen 13 Mar '09

13 Mar '09

http://dovecot.org/tmp/dovecot-1.1.12.rc.tar.gz I would have already released 1.1.12, but it needed the MAILBOXDIR change described below, and I'm slightly worried that it might have broken some special setup. So please test first and I'll release in v1.1.12 then in a few days. * Added :MAILBOXDIR= to mail_location to specify the root dir for mailboxes. dbox users should migrate to ":MAILBOXDIR=mailboxes", because that's going to be the default in v1.2+. - IMAP: SELECT didn't always return first unseen message in reply - POP3: pop3_lock_session=yes didn't use mail_privileged_group while dotlocking. - mbox: Don't crash if >=8192 bytes long line begins with "From ". - Maildir: More fixes to handling over 26 keywords. - Several logging fixes and improvements - Fixed authentication caching with non-plaintext mechanisms when using a blocking passdb (e.g. MySQL) - Fixed DIGEST-MD5 authentication with user@domain style usernames.

[Dovecot] Imap logout message on Dovecot restart
by RutgerM 12 Mar '09

12 Mar '09

I'm trying to receive a "Disconnected" message in my logfile for the connected imap-clients when I restart dovecot. When you disconnect a client, you receive the following message in your log: Mar 12 21:45:55 mail dovecot: IMAP(mailbox(a)domain.com): Disconnected: Logged out bytes=7496/22441 When a IMAP client is connected and Dovecot is restarted, this message is not shown. This should be solvable by a script like this: #!/bin/sh unset LOG_TO_MASTER export USE_SYSLOG=1 exec /usr/lib/dovecot/imap But this logs the user that runs the script into the imap server and when I terminate this terminal I get a "Disconnected" message for the local linux user, which I don't need of course. Is there a way to get to what I want ? I want to log my IMAP statics for every day and I need to "disconnect" my imap clients for it in some way to receive the Disconnected message and count from there. Thanks.

[Dovecot] High load/corrupted indexes after moving mailboxes?
by Patrick A. Treptau 12 Mar '09

12 Mar '09

Hello, we're experiencing an odd issue after combining two vDisks used for mail storage into one big new LVM. We've done this in the past successfully and didn't experience a lot of problems. We stopped all services (dovecot/postfix) to ensure that mailbox contents (Maildir) will not be changed, rsynch'ed the mail to the new disks and restarted everything. When we restarted dovecot, we noticed a huge spike in load (average load in top and high cpu iowait) and isolated dovecot as the issue. At some point, the average load crept up to over 100 and crashed the server twice. However, over time the average load and cpu wait times went down slightly. I have noticed a spike in load after moving user's mail storage, but not like this. It almost looks like everyone is either re-indexing or re-caching their mail? Any help would be appreciated. We're on dovecot 0.99. -Pat

[Dovecot] migration from dovecot to dovecot on different servers without downtime (dovecot replication?)
by Pau Oliva 12 Mar '09

12 Mar '09

Hello, I have an imap server with huge Maildirs and several users running dovecot 1.0.13, I need to migrate all the imap accounts to a new box which runs dovecot 1.1.4. The requisite is that need to do it with no downtime or minimal downtime possible, and totally transparent for end users. I have tried IMAP<-->IMAP syncing using a master user in both servers and imapsync, however due to the huge Maildirs (some users have more than 10 years of mail) this tends to be quite slow and painful. Can I tar all the user's Maildir and move them from one box to the other, and then run imapsync again? which I assume that would be faster... or is there any better solution I am not aware of? (ie: I've seen some emails about dovecot replication on the list archives, but few details of how that should be configured). I'd appreciate any feedback or thoughts on this matter. Thank you. Cheers, Pau Oliva

[Dovecot] GUI/WUI for creating (common) sieve scripts?
by Roderick A. Anderson 11 Mar '09

11 Mar '09

Anyone aware of a Web User Interface or GUI to allow users to create simple/common-type sieve scripts? I found the sieve testing and have used it as I play; plus mangesieve (and Net:ManageSieve.pm) but want to allow users to build so some clicking and maybe a little typing and then end up with some filters. So before I go invent this wheel I'd like to know what others are doing? TIA, Rod --

[Dovecot] dbox on CIFS

11 Mar '09

Ok - at this time I am using the following non-default settings: Samba server - smb.conf [Mailstorage] ea support = Yes use sendfile = Yes fake oplocks = Yes delete readonly = Yes Dovecot - dovecot.conf mmap_disable = yes dotlock_use_excl = yes fsync_disable = yes lock_method = dotlock I'm still testing - but at this time I'm seeing no errors. Two options I can state cause severe problems are the "directio" and "setuids" mount options for the cifs client. -- Daniel

[Dovecot] Error crosscompiling
by Diego Roversi 10 Mar '09

10 Mar '09

Hi, I was trying to crosscompile dovecot, but I got some error: --with-notify=inotify don't work, as it try to run a test program to verify if inotify is supported in the building platform. Solved with --with-notify=dnotify. Ihmo, is more a hack than a solution. | checking whether posix_fallocate() works... configure: error: cannot run test program while cross compiling I can't find an a suitable option for this error. Again the problem is that configure can't run an executable for a different platform. It's possible to set a safe default? Thanks in advance. -- Saluti / Regards Diego Roversi | | diegor at tiscalinet.it

[Dovecot] Random timeouts on mailboxes
by Bastien Semene 10 Mar '09

10 Mar '09

Hello, My dovecot server is currently having random issues when users want to acces their mailbox. When the issue is occuring there's a timeout. It's random because it happens more or less often and is not dependent on a user or the way their check the mailbox. The time during the problem occurs is random, sometimes it's less than a minute, sometimes it's some hours. When a user can't connect to its mailbox, he generally can receive its emails through his BlackBerry (it's just to illustrate the fact that it doesn't seem to be linked to an account). When this issue occurs they can't receive the headers from any folder (INBOX, custom, sent, ...) and can't read mails that headers are known by the mail client. When there's timeout, users can send emails (same jail and with an error when the client want to write a copy in the sentbox) and use the calendar server for example (on the same machine). Dovecot is running on a FreeBSD 7.0 32bits, 4GB RAM, Intel Xeon QuadCore @ 1.86 Ghz, and 3*500Gb SATA-2 RAID-5 disks. The box is hosting jails, and the mail jails ( imap + smtp, clamav + spamassassin ). The mail jails are new (since August 2008) but worked great since the beginning of this year. The server is hosting 122 accounts currently. My first thought was that there's an I/O issue, the disks are maybe too busy or there's paging that result in a timeout. I check it through vmstat an top commands but nothing appears, there's always some memory free (between 90-300 MB) and a very little paging, generally around 1MB. The fault are under a hundred and when, few times, it has more than a hundred (generally under 200) the next snapshot is under 100. I set the screen/line to refresh every 5 seconds. I shutdowned all jails not directly related to the mail service but the problem still occured. I also separated clamav and spamassassin from imap and smtp to a different box. After that I checked the dovecot config to lighten it, and ( only ) disabled fsync. I upgraded the RAM, added memory is used, but nothing changed. The human resources are constantly changing here, we were more before the problem started than now (around 10-15%), to illustrate the fact that I don't think it is linked to the number of users. I tried to recreate some accounts having the issue, but the problem appeared again. I upgraded Dovecot Friday to 1.1.11 from 1.1.7 (The installation was before 1.1.7, I did an upgrade some times ago). I used a command script to log Thunderbird's IMAP activity, everything is fine but there's no timestamp in the logs. So I'm only sure now this is not an erroneous packet/info sent problem. I watched the TB doc ( http://www.mozilla.org/projects/nspr/reference/html/prlog.html#25306 ) but there's no directive to put a timestamp for each line of log. The network is fine. I tried different configuration to be sure a device isn't doing something weird. Now, I don't know what to check to identify the issue. If anyone has any idea I didn't wrote here, or if I did erroneous interpretation(s) from the datas, I'll be glad to know. Regards, -- Bastien Semene Administrateur Réseau & Système
