[Dovecot] status of APPENDUID: returning a UID in response to APPEND
by martin f krafft 14 Aug '07

14 Aug '07

# dovecot-related content below, this one for debian bug tracking # system: retitle 435959 Please support RFC4315 UIDPLUS extension in APPEND reply severity 435959 wishlist thanks [please keep 435959(a)bugs.debian.org on Cc.] Hi there, I am working on http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=435959, which is a performance problem that offlineimap has on large mailboxes. We think that a simple patch to dovecot could cure this problem. I am willing to write the patch but would really like to get your opinion first. In order to keep track of which IMAP message is stored in which local file, offlineimap uses the message UID, which is guaranteed to be unique in the directory, but constant across sessions. When uploading a new message to the IMAP server with APPEND, offlineimap then has to run a SEARCH to obtain said UID for the message it just uploaded. This takes ages on larger mailboxes, as the way offlineimap identifies the message is via a header that's not indexed by dovecot. The solution I found in RFC4315 ("UIDPLUS"; http://www1.tools.ietf.org/html/rfc4315) and then I saw http://www.dovecot.org/list/dovecot/2004-July/003993.html, and now I am wondering: is anyone else interested in APPENDUID? What's the status of an implementation, if any? Newer Courier IMAP server implementation support UIDPLUS and offlineimap will likely obtain this functionality soon.

[Dovecot] dovecot-1.1 + dovecot-sieve-1.1 deliver backtraces

[Dovecot] logging dovecot-sieve vacation responses
by pod 13 Aug '07

13 Aug '07

I attach a patch that adds some informational logging for the vacation outcome in a similar style as the 'notify', 'redirect' and 'reject' cases. I considered adding logging for the not-willing-to-respond case since I think that would greatly assist testing/debugging vacation responses, but couldn't see where to put it that wasn't in the CMU code.

[Dovecot] plain authentication
by Roger D. Vargas 13 Aug '07

After upgrading my server I have found that Im not able to use plain auth for clients conecting from outside server. localhost clients (pine, webmail) works fine, but if I use Thunderbird I got an error saying that server requires TLS or SSL. But if I enable TLS or SSL I got more errors. I have tried sevral combinations, but havent found a working one. Here is my config, can somebody see what Im doing wrong? # /etc/dovecot/dovecot.conf protocols: imap pop3 ssl_disable: yes ssl_cert_file: /etc/ssl/dovecot/server.pem ssl_key_file: /etc/ssl/dovecot/server.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_greeting_capability(default): yes login_greeting_capability(imap): yes login_greeting_capability(pop3): no mail_extra_groups: mail mail_location: mbox:~/mail/:INBOX=/var/spool/mail/%u 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 auth default: passdb: driver: shadow userdb: driver: passwd -- Roger D.

[Dovecot] "pipe" plugin
by Nicolas Boullis 13 Aug '07

13 Aug '07

Hi, Long ago (more than 2 month ago), I told about a "pipe" plugin I had written to perform some spam/ham learning (see the attached message). I'm now proud to say that I can make it available for use by anyone. You can get it from http://nicolas.boullis.free.fr/pipe.tar.gz Note that this is a temporary location. If someone had a good place to host it, feel free to do (and tell). I think it would be great if the feature could be merged into dovecot. I don't care whether my plugin is used or a rewrite is performed... Cheers, Nicolas

[Dovecot] Inbox re-initialized
by Joshua, C.S. Chen 13 Aug '07

13 Aug '07

Hi folks, I just replaced my mail server's UW-imap with dovecot yesterday. I use the following folder setting default_mail_env = mbox:/asiaa/home/%u/:/asiaa/home/%u/mail/:INBOX=/var/mail/%u:INDEX=/asiaa/home/%u/mail/dovecot_indexes This is a Scientific linux 4.2 with dovecot 0.99.11-2 . Now today the server loading is highly reduced because of the pop3 session impact is low. But users have the following problems: For outlook express users, when they come in the office, the first time they launch outlook express, they found that the previous Inbox is re-transmitted. So they got double the number of all past e-mails (they setup OE setting to keep a copy on the server). And some users also use pine. After the pine session, they get another whole copy of the past e-mails (so some users got 3X or even 4X the past e-mails). Am I missing something for the dovecot.conf setting, here is the entire configurations: Thanks in advance protocols = pop3 pop3s imap_listen = [::] pop3_listen = [::] log_path = /var/log/dovecot login_dir = /var/run/dovecot-login login = imap login = pop3 default_mail_env = mbox:/asiaa/home/%u/:/asiaa/home/%u/mail/:INBOX=/var/m ail/%u:INDEX=/asiaa/home/%u/mail/dovecot_indexes mbox_locks = fcntl auth = default auth_mechanisms = plain auth_userdb = passwd auth_passdb = pam auth_user = root Cheers Joshua

[Dovecot] using complete email address as username
by WJCarpenter 13 Aug '07

13 Aug '07

I've been poking around the dovecot wiki, and this idea looks plausible. I'm just double-checking with the assembled experts to see if there is some "gotcha" that will happen to me down the road. I have in mind a deployment of dovecot which will use serve several unrelated domains. My plan is to use the complete email address of the users as the unique userid. So, for example, a user with email address <foo(a)example.COM> is unrelated to a user with email address <foo(a)example.NET>. The "home" directories of such users will look something like: /some/path/foo(a)example.com/ /some/path/foo(a)example.net/ I do also plan to use ACLs for some things, so there could be ACL entries of the form: user:foo@example.com ... I will probably be using the quota plugin for individual users right away and group quotas later when that's officially available. So, is all this likely to work or will it collapse in a miasma of unmet expectations? Thanks in advance for any comments!

[Dovecot] Deleting deleted eMails
by Michael Weisgerber 11 Aug '07

11 Aug '07

Hello 2gether, I am using Dovecot 1.0.rc15 together with Outlook (I apologize) via IMAPS. Now I discovered, that all the old eMails, I marked for deleting, are still there, even the veeery old ones. Dovecot is marking the eMails (I am using maildir configuration) files with an "ST" extension. Is there any switch to turn on garbage collection and maybe a screw to tune the duration until deletion? Thanks for your help! Michael Weisgerber

[Dovecot] dovecot: child 1690 (auth-worker) killed with signal 11
by Thomas Zajic 10 Aug '07

10 Aug '07

Hi there, I've been seeing this for quite a while now, but only today finally got off my lazy you-know-what and did a backtrace. Here's the requested info as per http://dovecot.org/bugreport.html: * Dovecot version [root@airframe]:~# dovecot --version 1.0.3 * Operating system or Linux distribution name Slackware 10.2, both kernel 2.6.21.3 and dovecot self-compiled * CPU architecture (x86 or something else?) x86 (AMD Athlon XP 3200+) * Filesystem you used (especially if you use NFS or not) ext3, local (no NFS) * Some kind of description of what you were doing and with what IMAP client. Thunderbird 2.0.0.4 (also happened with earlier versions) mail-notification-4.1 (" " " " " ) * If the problem can be reproduced, it helps a lot if you can tell how. Happens in almost regular intervals, not sure when exactly though. Usually when doing something in TB again (deleting or moving mails) after it has been sitting idling for a while. From the log files going back to July 22nd: [root@airframe]:~# grep "dovecot: child .* (auth-worker) killed with signal 11" /var/log/maillog* | wc -l 258 TB is configured to use TLS and secure authentication, use IDLE, and 5 cached server connections.

[Dovecot] Version 1.1 Alpha 2 Various Stuff
by Jerry Yeager 09 Aug '07

09 Aug '07

Some preamble information… OS X 10.4.10 (all updates) Power Mac Dual G5, 2.0 Postfix with Dovecot SASL, Dovecot LDA, Dovecot imaps (openssl) Mail clients Apple Mail v 2.1 SquirrelMail v 1.4.10a Thunderbird v 2.0.0.6 Mulberry v 4.06 For various versions of Dovecot, from 0.9m up through 1.0.3 things went well, no memorable big problems, with one exception: Mulberry v 4.0.8 would/will not work; i.e. it refuse(d) to connect saying it could not start SSL to begin the connection. Dropped back to version 4.0.6. I switched to version 1.1 alpha 2 (compile and configuration information is attached at the end of this message) 1) Started up Apple mail. Mail boxes disappeared in Apple Mail's list, except for the main Inbox mail box. Fixed by setting mailbox_list_index_disable = yes in the Dovecot.conf file, restarted both Dovecot and Mail, all the mailboxes reappeared and worked correctly. 2) Started up Squirrel Mail using several different browsers. No problems. 3) Started up Thunderbird. No problems. 4) Started up Mulberry. It partially connected, but stopped with the error saying that it had hit the limit for maximum connections. Mail logs show: dovecot: imap-login: Maximum number of connections exceeded: user=<username>, method=PLAIN, rip=192.168.1.1, lip=192.168.1.50, TLS I tried increasing the various limits in the Dovecot.conf file up through a maximum limit of 2048 connections, to no avail. Mulberry will initially connect to several of the mailboxes, but will stop without getting all of them and will throw up the 'over the connection limit' error and will then show you a dialog box that asks you to log-in. Attempting to doing so returns a fatal error 54. I have not tried Mulberry's version 4.0.8. 5) Mail logs had this message suddenly begin appearing: auth-worker(default): pam(username,192.168.1.1): pam_authenticate() failed: Authentication failure Fixed by completely commenting PAM authentication section out; It was: passdb pam { # [blocking=yes] [session=yes] [setcred=yes] # [cache_key=<key>] [<service name>] # ... essentially a placeholder section, since everything inside is commented out # # } now is: #passdb pam { # # ... even the outer block is commented out # #} The error has now disappeared from the logs.

[Dovecot] Crash with 1.1alpha2 when lazy_expunge is enabled?
by Rich at Whidbey Telecom 09 Aug '07

09 Aug '07

I'm seeing a crash in 1.1alpha2 when trying to expunge a folder when "lazy_expunge" is enabled: namespace private { separator = . prefix = .EXPUNGED/ location = maildir:/mailstore/%u/Expunged hidden = yes } ... lazy_expunge = .EXPUNGED/ .EXPUNGED/ .EXPUNGED/ Commenting out "lazy_expunge" prevents the crash and mail is expunged. It happens with and without ACL's. Attached is the log output. The messages never actually get moved to the "Expunged" directory, but there is a "temp" file created each time: /mailstore/testuser/Expunged/ drwx------ 6 testuser users 4096 Aug 9 11:39 . drwxr-xr-x 4 testuser users 4096 Aug 9 10:59 .. drwx------ 2 testuser users 4096 Aug 9 10:59 cur -rw------- 1 testuser users 24 Aug 9 11:39 dovecot.list.index.log -rw------- 1 testuser users 28 Aug 9 11:39 dovecot.list.index.uidmap drwx------ 5 testuser users 4096 Aug 9 11:02 .Junk -rw------- 1 testuser users 0 Aug 9 10:59 maildirfolder drwx------ 2 testuser users 4096 Aug 9 10:59 new -rw------- 1 testuser users 0 Aug 9 11:04 temp.mail4.whidbey.net.8596.7b344a891b2c6691 -rw------- 1 testuser users 0 Aug 9 11:32 temp.mail4.whidbey.net.8761.bfe04f5457e4ba7e -rw------- 1 testuser users 0 Aug 9 11:33 temp.mail4.whidbey.net.8765.44e803d87275348a -rw------- 1 testuser users 0 Aug 9 11:37 temp.mail4.whidbey.net.9031.f4a972591af59e05 -rw------- 1 testuser users 0 Aug 9 11:39 temp.mail4.whidbey.net.9125.d67b160254a01631 drwx------ 2 testuser users 4096 Aug 9 10:59 tmp Lazy expunge works on our production 1.0.0 systems.

[Dovecot] UW-IMAP style mbox snarfing from /var/mail/ to ~/mbox
by Timo Sirainen 09 Aug '07

09 Aug '07

http://dovecot.org/patches/mbox-snarf-plugin.c Also committed to CVS HEAD. Usage: mail_location = mbox:~/mail:INBOX=/var/mail/%u protocol imap { mail_plugins = mbox_snarf } protocol pop3 { mail_plugins = mbox_snarf } plugin { mbox_snarf = ~/mbox } If ~/mbox doesn't exist, nothing special is done. If ~/mbox exists, it's treated as INBOX and mails are moved from /var/mail/%u whenever the mailbox is synchronized. If all the messages couldn't be copied, for example because of out of quota, then none of the messages are copied. I suppose that could be a problem. It might be possible to fix that by changing: if (mailbox_copy(dest_trans, mail, 0, NULL, NULL) < 0) { if (!mail->expunged) { ret = -1; break; } } to just: if (mailbox_copy(dest_trans, mail, 0, NULL, NULL) < 0) { if (!mail->expunged) break; } But I'm not sure about that. Try and tell me. :)

Debugging information would have been really useful, but I did fix one bug and added some more asserts: http://hg.dovecot.org/dovecot-1.0/rev/bd113e9fe67b If it still wasn't fixed, maybe with this change it gives another assert.

[Dovecot] Outlook 2000/2003 frequent disconnect issue
by Jeff Ramsey 09 Aug '07

09 Aug '07

I have been using Dovecot for an IMAP server for a few years now, with no hitch. Even using Outlook 2K/2K3 as a client. Yesterday, I had a user experience the 'Negative UIDs' issue spoken of here: http://wiki.dovecot.org/Clients/NegativeUIDs I performed all of the steps mentioned in this article, and it seemed like it would work properly the first time the user checked their email, and then after that, they would get this error again. I checked to see what the latest stable version of Dovecot was, and decided to upgrade. I was at 0.99.11-8 and the latest stable rpm for my distro was 1.0.2-2. The upgrade went fine. Or so I thought. I am now getting the following message on all Outlook Clients: "Your IMAP Server closed the connection....this can occur if the connection is idle for too long" I have scoured the Internet for this error and have come up with many suggestions, none of which have worked. I have increased Outlook's timeout period to the full 10 minutes, and I have disabled SELinux. None of this seems to have worked. Is there anyone out there who has actually had this issue and resolved it? Can you please help?

[Dovecot] Database server failure causes endless loop
by Andy Shellam 09 Aug '07

09 Aug '07

Hi, I've just started setting up Dovecot 1.0.1, and made an error in my configuration, which I think has found a potential problem in Dovecot. I'm using PostgreSQL authentication, and set the database host to "localhost", which PostgreSQL doesn't listen on, so libpq is throwing the standard "is the server running?" message. The problem, however, is Dovecot isn't seeming to understand this, and is endlessly looping, trying to query it every 5 seconds. My client (telnet during testing) is simply sitting there waiting for a response, which it's never going to get. After about 5 minutes, Dovecot killed the connection, saying "* BYE Disconnected for inactivity." If this was from an IMAP client, I'm guessing the client would time-out after so long when it doesn't get a response back. Wouldn't it be more sensible for Dovecot to try PostgreSQL, say, 3 times. If unsuccessful, send the client an "internal server error" or something similar? Otherwise if the database server failed, and the client tries to connect, it'd be waiting for at least a minute (or whatever the standard time-out interval is) before failing, whereas it'd be better to see almost instantly if the server's down. Regards, Andy.

[Dovecot] Moving mboxes around
by tomas＠tuxteam.de 09 Aug '07

09 Aug '07

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Dovecot gurus, I have a couple of questions for which I haven't found answers in the docs (which may be well more a limitation of my capabilities than anything else). Here they go: - Is it OK to move mailboxes around from under Dovecot? Case in point: I'm using procmail to pass incoming mail through bogofilter (the standard recipe mentioned in their manpage, which more or less funnels spam into a "spam" mailbox, unsure into an "unsure" and non-spam into "inbox"). From time to time I'd like to clear the spam and unsure mailboxes, using logrotate. Dovecot seems to cope with it. Am I tempting my luck? - Is there a way to tell an external application when mail has been moved by a client? Again: dovecot+bogofilter: from time to time a client checks incoming, unsure and sometimes spam and decides to move --say-- a mail from unsure to spam (deciding it's spam, after all) or similar. This is of course important for the training of bogofilter, so I'd like to trigger a backend action. I see basically two possibilities: - create two more mailboxes, say "spam-indeed" and "ham-indeed". User is told to move mail into these. Ham-indeed gets re-funneled to inbox (or something like that). Manual and error prone. - Use the mail_log plugin (seems more attractive). I still have (distro-provided) dovecot 0.99.14, but this would be a good reason to upgrade. (I still don't see where I get the source mailbox in the mail_log messages from, but that's details now). You get the idea, I think. Anyway, I am interested in any ways to combine dovecot and bogofilter in the backend in a way that I can route user feedback to the filter without putting too much burden on the user. Ideas? Thanks - -- tomás -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (GNU/Linux) iD8DBQFGtuS4Bcgs9XrR2kYRAkiXAJoDJYZC8DYIxFqCw+HEIn0CCNssQwCfaZjh z533XFMH36c4Lemv/+gSn9A= =s87z -----END PGP SIGNATURE-----

[Dovecot] passdb/userdb restart
by Thomas Hummel 09 Aug '07

09 Aug '07

Hello Timo, I've noticed that when slapd which I'm using as the passdb and the prefetched userdb is restarted I have to restart dovecot. As a matter of fact, if I don't, I get the following error : -- Jul 2 16:38:39 xxxx dovecot: imap-login: Internal login failure: user=<xxxx>, method=PLAIN, rip=xxx.xxx.xxx.xxx, lip=xxx.xxx.xxx.xxx, TLS Jul 2 16:38:46 xxxx dovecot: auth(default): prefetch(xxx,xxx.xxx.xxx.xxx): passdb didn't return userdb entries Jul 2 16:38:46 xxxx dovecot: auth(default): userdb(xxx,xxx.xxx.xxx.xxx): user not found from userdb -- I'm using dovecot-1.0.1 on FreeBSD 6.2-STABLE with openldap-server-2.3.35_1 (bdb backend). Would some cache-related parameters allow to fix that or will restarting dovecot be always mandatory after an ldap restart ?

[Dovecot] 1.1.alpha2 error in logs

Did a quick-n-dirty install of 1.1.alpha2 on a Fedora Core 6 server... am getting the following message in the maillog, though there seems to be no problem accessing mail.

[Dovecot] lda: vacation auto-reply for a virtual address
by martin f krafft 09 Aug '07

09 Aug '07

Hi, I am using Dovecot to manage a complex virtual mailbox setup. It's all working splendidly, thanks to the Dovecot LDA. This morning, however, I needed to create a vacation-style autoreply for one of the virtual addresses. I made use of cmusieve, authored a little sieve script, and had it working in no time... until I discovered how limited sieve's vacation module is. Most importantly: it's hardcoded to use the Return-Path of a message, but in this very case, I need to actually use the address in the from header. So I had to give up on sieve and am now looking for another solution, but without much success. Given that mail is delivered by the Dovecot LDA, is there any way to make deliver pass it off to e.g. procmail in such a way that $HOME is set to /srv/vmail/domain.org/localpart, so that procmail can find the .procmailrc?

[Dovecot] LDAP and (py|cmu)sieve
by Thibault VINCENT 09 Aug '07

09 Aug '07

Hello, Before asking help, i would like thank Timo for this awesome server, it's lite, fast, and has good features. I've read the Wiki, tutorials, and tried various configurations to get the result I expect. My company is running a dovecot 1.0.0 server set up with an LDAP directory, mails are delivered to /var/spool/imap and users do not have a real unix home directory on this system. During my internship, I've installed a sieve server (pysieved) that is working with dovecot. But I encountered a problem with the LDAP setup. Pysieved is using dovecot's auth and client sockets to authenticate the user and get it's home directory where it will store sieve scripts, this home directory is also actually used by cmusieve. With our setup, users do not have /home directories on the mail server but the homeDirectory LDAP attribute is used by other services and cannot be modified for dovecot. I know we have the option to create a new attribute, set it to something like /var/spool/imap/<user> for every mail users, and use this new attribute name in dovecot-ldap.conf with the user_db statement. This is actually working on a test environnement, but we wish we could do it without any modification on the LDAP directory. The very precise question is : How can I tell dovecot to compute the « home » path from the login name when using LDAP userdb ? By example, if a user has login name "jdoe", dovecot will authenticate him against the LDAP directory but won't get the home path from it. Instead, it will use the same mail_location path (if possible) or something similar, like /var/spool/imap/%1u/%u . Can I do this without any modification of the source code of both dovecot and pysieved ? Thank you, -- Thibault VINCENT tibal(a)reloaded.fr thibault.vincent(a)reloaded.fr PGP Key : 0x4BA8A39B

[Dovecot] HP-UX troubles
by Matthias Luehr 09 Aug '07

09 Aug '07

Hi there, I got dovecot compiled and running on HP-UX 11.23. It's using LDAPUX and PAM for authentication. So far, it works. But after logging in the connection is closed immediately. It looks like this: telnet <ip> 143 Connected to ... Escape character is '^]'. * OK Dovecot ready. a01 login <user> <pass> Connection closed by foreign host. The dovecot log says: Error: imap-login: fd_send(7) failed: Bad file number Error: child 22629 (login) returned error 89 As far as I can see, the problem seems to reside in dovecot's fdpass.c... dovecot version: 1.0.3 gcc version: 2.9 Any ideas or solutions? Thanks in advance, Matthias

[Dovecot] UIDL match from 0.99.13 to 1.0-1.2
by Daniel Davidson 09 Aug '07

09 Aug '07

I am moving from and old FC2 system to a new RHEL5 system and am having trouble getting the UIDLs to move over right, mainly the UID. I copy over the mailbox, and see the x-uid in the message is what it was on the old server, but when I telnet in to check pop, it rewrites x-uid in the message to something new, causing old messages to get downloaded again, which is not what we want I have tried setting pop3_reuse_xuidl to yes, but that did not change anything, probably because that is the wrong header (I do not have x-uidl, but I do have x-uid). I do have pop3_uidl_format set to %v.%u for compatibility. On the old system the first five are: +OK Logged in. uidl +OK 1 1095087961.3092736 2 1095087961.3092737 3 1095087961.3092738 4 1095087961.3092739 5 1095087961.3092740 On the new system the first five are: +OK Logged in. uidl +OK 1 1095087961.3093018 2 1095087961.3093155 3 1095087961.3093156 4 1095087961.3093157 5 1095087961.3093158 Any help would be appreciated, I do not understand how it is generating the UID portion.

[Dovecot] Userdb and home directories
by Mike Brudenell 09 Aug '07

09 Aug '07

Greetings - I've just discovered an oddity I didn't know I had... We have two NetApp filers: one serves people's home directories; the other their message store and control files filestores. At the moment the first of the two filers is not accessible to my Dovecot system and I assumed all would be well because, as far as I knew, I wasn't using it at all. However in practice Dovecot DOES appear to be using it: it is trying to chdir() to my home directory when I login, finds it can't at the moment (because of a problem giving "Permission denied"), and closes the connection. I've read the pages on home directories and the userdb on the Wiki and it advises that having a home directory is beneficial. I'm happy to create a subdirectory for this within a user's control files directory, but do NOT want it on our normal filestore: we can't have mail inaccessible because a user's home directory is inaccessible because the other filer is out of action. We use shadow for the passdb and passwd for the userdb (see dovecot - n output below). I'm trying to work out how to override the home directory returned from NIS. Ultimately I'd like to use this template: /mailstore/control/%1Ln/%Ln/home but for the time being while I'm trying to work out how to do it have my own area hard-coded in (as it's only me logging in to the test system): /mailstore/control/p/pmb1/home I'm specifying this with the "args" directive in the userdb section as follows: args = home=/mailstore/control/p/pmb1/home but it isn't being picked up. What am I doing wrong, please? (We want to continue using uids and gids etc from NIS so I don't think using the static userdb is the right thing to do?)

[Dovecot] dovecot-sieve vacation changes
by pod 09 Aug '07

09 Aug '07

I'd like to put forward the following patch for dovecot-sieve. Essentially this just merges in some changes made in CMU sieve 2.3.8 and as such brings the behaviour more in line with RFC 3834 "Recommendations for Automatic Responses to Electronic Mail": - fixes erroneous sender "-request" substring match - checks for existence of a selection of list-* headers - expands "named-as-recipient" header checks to "Resent-To", "Resent-CC" and "Resent-BCC" fields. Note that the appended patch also includes a fix for some missing parentheses in the "resent-to" test which resulted in some extra work being done but was otherwise harmless. The fix has been sent to <cyrus-bugs+(a)andrew.cmu.edu> - prefixes subject in response with "Auto: " rather than (non-expanding) "Re: " I also, mostly for kicks, attach two sieve-like scripts that attempt to encapsulate the when-not-to-respond logic as implemented (if the patch were to be applied) and as advised by RFC 3834 respectively. I wrote these as an exercise to help me gain a better understanding of sieve and the CMU implementation. I'm not sure they are otherwise useful.

[Dovecot] NFS rquota support
by Timo Sirainen 09 Aug '07

09 Aug '07

For v1.1, probably applies to v1.0 code pretty easily too: http://hg.dovecot.org/dovecot/rev/078d9dde99c8 The other rquota patches had authunix_create_default() call. Is this needed/useful? The client is now always created+destroyed for each quota lookup. I'd think it would be faster if it was created only once, but does it then break something? If the above isn't done, clnt_create() could be replaced with clntudp_create() and have the struct sockaddr_in cached. Patches welcome. :)

[Dovecot] Shared folder hierarchies, multiple groups
by Benjamin R. Haskell 09 Aug '07

09 Aug '07

Hi, I'm trying to set up two shared folder hierarchies on my Dovecot installation for two groups of employees, all of whom should only have access to their own hierarchy. Any employee should be able to create sub-folders and generally have full access to the hierarchy. My initial setup was to create two public namespaces, Shared-One and Shared-Two. Each is a Maildir under /var/mail. The actual shared folders seem to be working fine in terms of adding and accessing folders and messages, and there are no problems at all for the 'admin' user, who belongs to both the shared1 and shared2 Unix groups. The problem is for other users, where trying to (IMAP-) LIST folders fails. (sanitized) IMAP session log: ('user2' is in group shared2) * OK Dovecot ready. A LOGIN user2 pass A OK Logged in. B LIST "" "%" * LIST (\Noselect \HasChildren) "/" "Shared-One" B NO Internal error occurred. Refer to server log for more information. [2007-08-02 09:01:23] In the mail logs I find: dovecot: IMAP(user2): stat(/var/mail/Shared-One/cur) failed: Permission denied Relevant permissions: 2770/drwxrws--- shared1 shared1 /var/mail/Shared-One 2770/drwxrws--- shared1 shared1 /var/mail/Shared-One/cur 0660/-rw-rw---- shared1 shared1 /var/mail/Shared-One/dovecot-shared And similarly for Shared-Two. (replace shared1 with shared2 everywhere) Among other things, I've read: http://wiki.dovecot.org/SharedMailboxes http://wiki.dovecot.org/ACL http://wiki.dovecot.org/MainConfig http://wiki.dovecot.org/Namespaces I don't want to use vfile ACL's (I think) because I want users to be able to create subfolders at will, and I don't want to have to add a dovecot-acl file per-folder. (Is there a way to set global defaults on a global basis? [not per-folder]) I also think there would be a problem with the hierarchies being similar. (e.g. both have a 'Projects' sub-folder, but there's a pretty clear WARNING on the wiki about mailbox name conflicts.) I can't use symlinked Maildirs, because new subfolders get created under ~user/Maildir/. (Want them under /var/mail/Shared-X/) I can't use hidden namespaces, because employees use Outlook (uggh), and I couldn't figure out how to "find" the namespace when it was hidden. (That seemed like the closest thing to a solution - it solved the LIST problem.) Ideally, Shared-Two wouldn't even be visible to members of Shared-One, and vice versa. But, that's at least an acceptable "problem" I could live with. Any suggestions? Thanks, Ben

[Dovecot] Bug in Exim->Dovecot auth

Hi. I'm using SMTP auth with Exim authenticating against Dovecot's auth socket.

[Dovecot] Authentication problem - or is it?
by Anne Wilson 09 Aug '07

09 Aug '07

My old server ran v.0.99, and this is the first time I've tried to get v.1 running. When I try to test it with telnet I see telnet localhost 143 Trying 127.0.0.1... Connected to david.lydgate.lan (127.0.0.1). Escape character is '^]'. * OK Dovecot ready. x login anne xxxxxx x OK Logged in. Connection closed by foreign host. I assumed it was an authentication problem (I want to use /etc/passwd as the authentication file) but it does say that I managed to log in. If so, what could be causing it to close immediately? Anne

[Dovecot] v1.1.alpha2 released
by Timo Sirainen 09 Aug '07

09 Aug '07

http://dovecot.org/releases/1.1/alpha/dovecot-1.1.alpha2.tar.gz http://dovecot.org/releases/1.1/alpha/dovecot-1.1.alpha2.tar.gz.sig Hopefully the next release can be v1.1.beta1. I'm not aware of any major problems and I think I'm pretty much done with new features (except for dbox). The largest changes since alpha1: * Removed THREAD indexing. It's a bit buggy and I think there's a better chance of releasing a bugfree v1.1 soon if it's not included. I'll fix it after v1.1. * Removed THREAD=X-REFERENCES2 also because it wasn't as easy to implement with the old threading code. I might put this back though if there's enough interest. * PAM always works in blocking=yes mode now. If you have problems with memory leaks, change auth_worker_max_request_count setting. + Filesystem quota backend supports inode limits, group quota and RPC quota for NFS. + SEARCH and SORT finally compare all characters case-insensitively. We use i;unicode-casemap algorithm. + Config files support splitting values to multiple lines with \ + Winbind NTLM and GSS-SPNEGO mechanism patches by Dmitry Butskoy.

[Dovecot] Not seeing other folders with some clients

Hi, With dovecot 1.0.2, depending on the client I can only see inbox, or all the folders. I see all the folders with pine and balsa, but can see only the inbox with squirel mail and thunderbird. Any idea what's going on here ? Thanks. Yves. ---- Yves Dorfsman yves(a)zioup.com http://www.SollerS.ca

[Dovecot] BUG (and suggested fix) in maildir code
by Tom Vajzovic 08 Aug '07

08 Aug '07

Hi all I'm using dovecot 1.0.rc15 to serve a maildir by IMAP. I have an IMAP subdirectory called subscriptions. The messages are in maidir/.subscriptions/cur/ etc. Dovecot is renaming the directory .subscriptions/ to subscriptions/ This means that when my IMAP client requests this directory, it gets the message "no such directory", and dovecot also gives the error message: dovecot: IMAP(tcv): read() failed with subscription file /var/mail/maildir/tcv/subscriptions: Is a directory The two should be able to live happily side by side, with the subscriptions file called "subscriptions" and the maildir called ".subsciptions". The offending function is maildir_subscriptions_convert_099() in src/lib-storage/index/maildir/maildir-storage.c Can someone with developer access please change this so that rename() is not called if subscriptions is a directory. Thanks, Tom

[Dovecot] dovecot.conf an <TAB> chars
by Sascha Holzleiter 08 Aug '07

08 Aug '07

Hi, I just wanted to "beautify" my dovecot configuration file and as one of the first comments suggests whitespaces and <TAB> should be completly ignored but that doesn't seem to be the case, e.g.: postmaster_address<TAB>= some(a)address.de results in an configuration error as the postmaster_address is not set. Using just a space or replacing the <TAB> char with space chars resolves the problem. This is with dovecot version 1.0.3 on Debian and FreeBSD. Greetings, Sascha

[Dovecot] OpenBSD and too many open files
by Bryan Vyhmeister 07 Aug '07

07 Aug '07

I posted some questions a few months back and received lots of great help in getting my dovecot/postfix/LDAP setup working. Initially, I ran into the pipe failed too many open files error. I am running this setup on OpenBSD/sparc64 4.1-stable and so I put dovecot in its own class and upped the maxfiles setting for that class. This was back with dovecot 1.0 and everything worked fine. I just recently upgraded to dovecot 1.0.2 from ports and now I am having the same problems again. I moved kern.maxfiles for that class from 2048 up to 3404 and yet I still run into the error. When I do, I have to restart dovecot to get things running again. Output of: su -c dovecot root -c 'ulimit -a' time(cpu-seconds) unlimited file(blocks) unlimited coredump(blocks) unlimited data(kbytes) 1048576 stack(kbytes) 8192 lockedmem(kbytes) 634482 memory(kbytes) 1898080 nofiles(descriptors) 3404 processes 1044 sysctl kern.maxfiles gives: kern.maxfiles=3404 My main IMAP accounts reside on this server and I have somewhere in the 25000 range of stored messages. Could this be causing the issue? I only have maybe a dozen other users using this server right now but I am planning on putting 500 users on it soon. I added another heavy IMAP user shortly before these problems started but I don't know if that has anything to do with it or not. Likewise, I am not sure if the dovecot 1.0.2 upgrade had any effect either although it did coincide. Any ideas? Thank you. Bryan

[Dovecot] vfile ACL's
by Benjamin R. Haskell 07 Aug '07

07 Aug '07

(Sorry for the impatience. This was one of several questions in my email from yesterday. I thought I might have better luck being more direct.) Is there a way to set ACL's, using the vfile backend, on a truly global basis? or hierarchically (i.e. .Maildir.Sub inherits from .Maildir)? The wiki page says: "The default ACLs for mailboxes is to give owner all permissions and other users none. Mailboxes in public namespaces don't have owners, so by default no-one can access them." Is this configurable? Thanks, Ben

[Dovecot] dovecot + LDAP-SASL ?
by Hadmut Danisch 07 Aug '07

07 Aug '07

Hi, just a question: I know that dovecot supports SASL authentication and supports LDAP. Which means that dovecot performs the SASL methods itself and stores the plaintext secret on LDAP. But it is also possible to have the LDAP do the SASL work and dovecot just pass SASL messages through? Even when the LDAP server uses a proprietary SASL method not supported by dovecot? regards Hadmut

[Dovecot] Ideas for Webmail/OTP
by Frank Behrens 07 Aug '07

07 Aug '07

I want to discuss some problems/enhancements for dovecot in a webmail/otp setup. For access to an IMAP server like dovecot I see different client types: a) a "normal" MUA installed in a more or less trusted environment b) remote access via "webmail" from untrusted environments For a) I see with dovecot and other IMAP servers no problems, tricky is the setup for b). If you use a webmail client in an untrusted environment the risk is high, that keyloggers and other malware steal your password. One easy solution is to use One-Time-Passwords (OTP). The otp setup for interactive logins (e.g. ssh) is easy, but until now I did not find any easy to use solution for webmail. The main problems I see - In most cases a webmail client does not hold a persistent connection to the IMAP server, but makes a login for every request. - The webmail clients are not prepared to display the otp password challenge to the user. When we say "otp" with IMAP we further have to distinguish a) the OTP SASL authentication mechanism b) OTP configured by PAM. I believe a) is implemented in new dovecot 1.1 version, but I prefer b), because - it works with many clients without special client support - all authentication setup is central in the os. All above described problems are not specially linked to dovecot, but I believe with dovecot there is an easy solution to solve them. :-) Solution 1: When PAM is configured for IMAP the user can use a one-time-password in the same way as before. The problem is, that the user must know the sequence number for the password (otp challenge), so we need a way to display it. The PAM module supplies the otp challenge in the conversation function, but the challenge is not processed by the IMAP server. My proposal: The IMAP server stores the challenge from the conversation function and includes it in the LOGIN response, when the login was not successful. So a user can try a login with a wrong dummy password and get knowlegdge about the current otp sequence. The webmail server should be extended in a way, that it displays the complete IMAP error message, when a login fails. Solution 2: Webmail clients do not use persistent connections in most cases. A OTP login needs different passwords for every displayed web page. My proposal: Use dovecot's login cache and do not ask the os for every login. :-) Solution 3: When we configure PAM we can restrict/allow it's use depending on IP address of client. Unfortunately with a webmail client the IMAP client is always the the webserver. It should be possible, that the webserver forwards the client IP address to the IMAP server. Furthermore to use dovecot's login cache as described above in a safe manner, the IP address should be compared, too. My proposal: Create a new IMAP command "XSETREMOTEIP". With this IMAP extension a client can set the real IP address of remote client. The access to this command is restricted to the webserver with a new configuration parameter "trusted clients", which holds an IP address with mask. I ask to discuss these solutions. It seems to work, I'm making the first tests now. I have patches for dovecot and squirrelmail, but they are very "quick and dirty". They show a possible solution, but not a clean implementation. Do you believe, that we can build a good webmail system this way, or do you have better solutions?

[Dovecot] [PATCH] Split sql drivers from lib-sql to plugins
by Tomas Janousek 07 Aug '07

07 Aug '07

Hi, in order to solve rhbz#170960 [1], I split the sql drivers to plugins so that they are loaded dynamically and can be split to separate packages. [1] https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=170960 The patches are here: [2] http://people.redhat.com/tjanouse/dovecot/145241/dovecot-1.0-split.patch [3] http://people.redhat.com/tjanouse/dovecot/145241/dovecot-trunk-split.patch (mv src/lib-sql/driver-mysql.c src/plugins/sql-mysql/, etc., afterwards) I'd like to ask for your comments and whether it's ok for inclusion or at least ok to use in the Fedora package. Regards, -- Tomas Janousek, SW Engineer, Red Hat, Inc.

[Dovecot] cache questions
by Daniel Watts 06 Aug '07

06 Aug '07

Hi Guys, We have: auth_cache_size = 2048 #Kb auth_cache_ttl = 900 #life of the cache Seems to work well (though haven't tried looking at stats). Only problem is that every so often, one of our new users tries to log in quickly before the account is marked (in a db) as 'active'. They use the right password but the sql query fails because the active flag is not yet set. This results in their trying to log in and failing for 15 minutes (900 seconds) until the cache clears. Is this dovecot caching negative results? Is this a good idea and can it be disabled? Some more questions: 1. Is the expire time on a per-login basis or for the entire cache? If someone logs in 14 minutes after the last expiry is their data cached for just 1 minute? 2. If it is per-login, is the time reset after every hit? If someone is using webmail and hitting the cache every 5 minutes, will the cache keep the information? 3. How does the cache size relate to number of distinct logins? Roughly how many auth datasets cached per 1MB of cache? Thanks! Daniel tg3 dovecot # dovecot --version 1.0.rc27 p.s. please CC my email so I know when this has been replied to. I will respond to group!

[Dovecot] Benchmark: Appending 250k messages
by Timo Sirainen 06 Aug '07

06 Aug '07

I just changed Dovecot v1.1 code to work much more nicely when appending new messages to large mailboxes. Dovecot hg (cydir format, fsync_disable=yes): ./imaptest secs=1 ./imaptest - append=100,0 logout=0 msgs=10000000 clients=1 seed=1 secs=300 Logi Sele Appe 100% 100% 100% 1 1 2322 1/ 1 0 0 1998 1/ 1 0 0 2293 1/ 1 0 0 2009 1/ 1 0 0 1789 1/ 1 0 0 1245 1/ 1 0 0 43 1/ 1 0 0 32 1/ 1 0 0 881 1/ 1 0 0 2137 1/ 1 .. 0 0 704 1/ 1 0 0 771 1/ 1 0 0 388 1/ 1 0 0 831 1/ 1 0 0 572 1/ 1 0 0 766 1/ 1 Totals: 1 1 251397 Averaging 837/sec. The append speed jumps around quite a lot. Typically it's around 800-1000/sec, but it jumps between 0-500/sec also quite often. I'm not sure why that is. Cyrus v2.3.8 (fsync and fdatasync calls disabled from code): ./imaptest - append=100,0 logout=0 msgs=10000000 clients=1 seed=1 secs=300 Logi Sele Appe 100% 100% 100% 1 1 2587 1/ 1 0 0 1907 1/ 1 0 0 1597 1/ 1 0 0 1260 1/ 1 0 0 1220 1/ 1 0 0 1151 1/ 1 0 0 1068 1/ 1 .. 0 0 121 1/ 1 0 0 127 1/ 1 0 0 128 1/ 1 0 0 126 1/ 1 Totals: 1 1 79613 Averaging 265/sec. The speed slows down pretty consistently, there's no jumping like with Dovecot.

[Dovecot] Disable IMAP for certain users, but not Webmailer
by FORMER 03 | Baltasar Cevc 06 Aug '07

06 Aug '07

Hi everybody, I'm planning to set up our new mail system using the Dovecot mailbox server. It mostly works fine yet (it's quite straigt forward to set up, I'd say), but there's a thing I haven't been able to find out yet. We provide POP3 access for all users, but want to restrict IMAP access to some of them (because IMAP users tend to leave more messages on the server, thus increasing storage needs). I used to do it by providing two services. One provided the public imap and checked a database flag during authentication, the other just provided IMAP on localhost and did not check the "allowed to use IMAP" flag. What I've found for Dovecot is http://wiki.dovecot.org/Authentication/RestrictAccess While this allows me to provide full POP3 to everybody and in the same time restricting IMAP, I don't see a possibility Is there any possibility to achieve what I need without having two completely separated instances of Dovecot running? I'd appreciate any hints, pointers to documents etc. Thanx, Baltasar -- _____ FORMER 03 GmbH _____ infanteriestra§e 19 haus 6 eg _____ 80797 muenchen _____ baltasar.cevc(a)former03.de _____ www.former03.de _____ fon 089.322112.29 _____ fax 089.322112.11 _____ mobil 0178.691.2233 _____ geschftsfhrer _____ sebastian fiedler _____ gert zellentin _____ handelsregister _____ HRB Mnchen 148468 _____ steuer _____ ust.-id DE 2291076876

[Dovecot] dovecot.index.cache weirdness
by Tan Shao Yi 06 Aug '07

06 Aug '07

Hi Timo, Just a quick check, may I know if the following output of idxview is normal? (see bottom of e-mail) I am running dovecot-1.0.3 on a Solaris 10 SPARC box. Deleting dovecot.index.cache does not seem to help for this user; it keeps getting regenerated with these same lines. I seems that I have to set mmap_disable=yes on this box to have a "clean-looking" dovecot.index.cache. Is it mmap related? Or it just happens to be a coincidence?

[Dovecot] Some of my IMAP Folders vanished in some MUAs
by Dominik Schulz 05 Aug '07

05 Aug '07

Hi, I'm using dovecot for some time now. Previously I was using Courier and I've migrated this setup to dovecot which went pretty fine. Now I'm experiencing some strange behaviour when using some newer mail clients. Some of my Folders, like "spam", are vanished. The strange point is that it only happens in some clients, like Thunderbird 2.x+ or KMail 3.5.x. In others, like Thunderbird < 2, Mutt or my Webmailer (Horde) they still show up. These folders are still there, i.e. in the filesystem, and the permissions seem to match those of the other folders which can be seem in all MUAs. I don't know if this is even related to dovecot but I think this is where I should start looking for an solution. I'm using dovecot 1.0.rc15 from Debian (stable/etch). It'd be great if anyone was able to help me. Thanks in advance. Best Regrads Dominik Schulz

[Dovecot] Password Encryption
by Dave Morrow 05 Aug '07

05 Aug '07

Hi all. I hope this is not a RTFM-type question, but I've been unable to find a searchable archive of this mailing list....... I recently began investigating using Dovecot/Postfix/MySQL solution. I've been following the documentation http://wiki.dovecot.org/HowTo/DovecotLDAPostfixAdminMySQL?highlight=%28m ysql%29 While everything seems to have gone right, I have been unable to successfully login to the IMAP server using Outlook Express. It seems that the problem may relate to PostfixAdmin storing passwords in the mysql database md5 encrypted, and Dovecot is not able to read them, but I am not certain. The error when a client logs in is something like dovecot: auth-worker(default): plain_md5_verify(testuser1(a)mydomain.com): Invalid password encoding David Morrow Technical Systems Lead Autodata Solutions Company David.Morrow(a)Autodata.net <mailto:David.Morrow@Autodata.net> http://www.autodatasolutions.com <http://www.autodatasolutions.com/> Tel: (519) 963-3020 Fax: (519) 451-6615 Think slowly.

Yep... and we have 500K very active users on it. We've scaled Dovecot horizontally without NFS, just lots of independent Dovecot server intances with smart proxy/mail-routing infrastructure around it. It can easily scale to millions of users this way. Just make sure you throw enough disks at it and you'll be fine, with or without NFS. > Do you think it's a good solution to use one synchronised local Openldap on each > server Dovecot ? No. I'd replicate your ldap database on a few servers that are dedicated to that purpose, and on each mail server use Dovecot's auth_cach feature to minimize how often it needs to query ldap. > Do you think It's possible to use Postgresql or MySQL instead of Openldap ? We use MySQL. MySQL handles frequent writes better than OpenLDAP from our experience. It is also simpler for us to do replication and troubleshooting because we employ several MysQL gurus already. > Are cyrus or courrier-imap better solutions ? Definitely not courier-imap, because of it's lack of indexes. Not sure about Cyrus. > Someone say "Zimbra is highly scalable and fast", I think Zimbra could be to heavy > in this architecture, is Dovecot scalable ? My opinion is Zimbra is too heavy beccause of the way mail is stored on the backend. Dovecot with maildir scales out well, and the promise of dbox mail storage format appears that it will make it even more scalable down the road. Bill

[Dovecot] MD5 mis-match
by Big Pizzle 03 Aug '07

03 Aug '07

Hi all, I'm almost finished building our new load balanced email server that are attached to an NFS mountpoint. There are currently two e-mail servers connected to the NFS share. Both email servers are running CentOS 4.5 with Postfix 2.4.3, Dovecot 0.99, and authenticating via LDAP. Dovecot is using Maildir format. I've been trying to do some benchmarks using Postal and Rabid, and whenever I run rabid, I'm getting errors like this: MD5 mis-match, calculated:a628289996ce19910ebbd4eef2ebc3fc, expected 9406a7cf56afb5a1308eb5377e141719! However, when I tail the /var/log/maillog, I don't see errors - I just see the pop3-login. Just wondering if that is okay. I've also been trying to find an RPM for Dovecot 1.0.3, with no avail. Anyone know where I can get one? Thanks in advance. Patrick

[Dovecot] Looking for RPM for 1.0.3 for CentOS with imap, ldap, and ssl
by Big Pizzle 03 Aug '07

03 Aug '07

Hi, I don't know how to compile Dovecot from src rpm;s - in fact I tried and failed miserably. The only other src rpm I have ever built was postfix, and I ran into a whole bunch of errors trying to build an rpm from the src rpm at ATRpm. Anywho, I was wondering if one of you wonderful Dovecot members would be willing to create an RPM for CentOS 4.5 that includes ldap and ssl. Or, if someone knows of a URL I can go to and follow a Dovecot-related src rpm build tutorial, that would be of great help too. Heck - I'll even settle for a 1.0.2. Since Dovecot doesn't support 0.99 I want to make sure I have the most recent package. Thanks in advance. Patrick

[Dovecot] Dovecot strong or not for a big Webmail architecture
by John fistack 03 Aug '07

03 Aug '07

Hello, Do you think Dovecot could handle millions of active users in a big architecture ? This cluster could be for example (each server is a bi quad Xeon 2.66 Ghz) : - 40 Dovecot servers - 4 LVS - 20 Apache+PHP - 2 Openldap - 20 Postfix + ClamAV + SpamAssassin - 1 NFS Netapps For millions of user it could be multiple different clusters of 40 Dovecot servers with 1 Netapp for each cluster. I want to work in NFS. I've experimented problem with Cyrus and NFS on Netapp. I want to use maildir, I can manage limitations of inodes with Netapp. I know webmail.us use Dovecot, what is the most big dovecot architecture known ? Do you think Dovecot can handle 1 million of active users in a good architecture ? Do you think it's a good solution to use one synchronised local Openldap on each server Dovecot ? Do you think It's possible to use Postgresql or MySQL instead of Openldap ? Are cyrus or courrier-imap better solutions ? Someone say "Zimbra is highly scalable and fast", I think Zimbra could be to heavy in this architecture, is Dovecot scalable ? Thank you for your ideas. Regards.

[Dovecot] dovecot 1.0.2, sieve 1.0.2 and regex
by Alexander Hoogerhuis 03 Aug '07

03 Aug '07

I've just ported a largeish procmail script across to sieve and want to get to use wildcards in filing mail and can't seem to get regex to work. The script starts nicely with: > require ["fileinto","regex","envelope","vacation","regex"]; and a bit down these few lines comes into play: > elsif header :regex "From" "logwatch.*stuff.com" { > fileinto "INBOX.Admin/Logwatch Stuff"; > } and regex just never seem to catch. I have 50ish machines in the stuff.com domain, and writing an induvidual section like this works: > elsif header :contains "From" "logwatch(a)a.stuff.com" { > fileinto "INBOX.Adin/Logwatch Stuff"; > } > elsif header :contains "From" "logwatch(a)b.stuff.com" { > fileinto "INBOX.Adin/Logwatch Stuff"; > } etc. But this shouldn't be neccesary? mvh, A

by Steffen Brunk 02 Aug '07

02 Aug '07

Hello list, my name is Steven and of course: I got a problem... we are using dovecot 0.99 because it´s the actual stable version for RedHat 4 Enterprise. I am trying to authenticate using "PLAIN" but I don´t know how. that´s what I am doing: telnet conny.MYDOMAIN.de 143 Trying IP.AD.RE.SS... Connected to conny.MYDOMAIN.de. Escape character is '^]'. * OK dovecot ready. a1 authenticate plain + a1 NO Authentication failed. what do I have to send after receiving the "+"-symbol? dovecot is waiting for something base64-encoded and I tried to give him by typing my username and pass and encrypted it here : http://www.php-einfach.de/base64_generator.php But I don´t know the correct syntax and it drives me crazy.... thanks for ANY help Steve .

Hi all I've got a standard dovecot setup: home is /var/spool/vmail/domain/user/ uid: vmail gid: vmail Sieve file is: /var/spool/vmail/domain/user/.dovecot.sieve if i want to change the dovecot-sieve file to modify the rules (or even let my users do it at some point) then it has to been done by root. Is there a way to setup the sieve plugin so a user can create his own rules? sort of like ~/.procmailrc TIA jalal

[Dovecot] v1.0.3 released
by Timo Sirainen 02 Aug '07

02 Aug '07

http://dovecot.org/releases/1.0/dovecot-1.0.3.tar.gz http://dovecot.org/releases/1.0/dovecot-1.0.3.tar.gz.sig - deliver: v1.0.2's bounce fix caused message to be always saved to INBOX even if Sieve script had discard, reject or redirect commands. - LDAP: auth_bind=yes and empty auth_bind_userdn leaked memory - ACL plugin: If user was given i (insert) right for a mailbox, but not all s/t/w (seen, deleted, other flags) rights, COPY and APPEND commands weren't supposed to allow saving those flags. This is technically a security fix, but it's unlikely this caused problems for anyone. - ACL plugin: i (insert) right didn't work unless user was also given l (lookup) right. - Solaris: Fixed filesystem quota for autofs mounts.

[Dovecot] mbox inbox default
by bhayden＠umn.edu 01 Aug '07

01 Aug '07

HI Timo & all. We're an mbox environment, inboxes in /var/mail/$USER (I'll include dovecot -n output at the bottom of this mail). mail_location is set accordingly for deliver. I'd assumed that if the /var/mail/$USER file doesn't exist, dovecot would create it, but we've discovered from experience (and I verified it in mbox-storage.c) that if access(path, R_OK|W_OK) fails--as it does if the file doesn't exist--that dovecot defaults then to delivering in root_dir/inbox. I'm curious why this is. It seems like if the configured INBOX file doesn't exist, dovecot should create it if possible; it's a different case than if, say, the user doesn't have write access to that directory, in which case it of course would be appropriate to fall back to some other location rather than rejecting mail. Is there something I'm missing that makes my idea wrong?

[Dovecot] Missing MIME-Version header in e-mails.
by Tan Shao Yi 01 Aug '07

01 Aug '07

Hi, I notice that in src/lib-mail/message-parser.c, there is a section of code that checks for the presence of MIME-Version before allowing processing of the Content-* headers. Is there a possibility of relaxing this rule? There are some broken mailers, in particular newsletter mailers that do not seem to honour the MIME-Version header, though they do send the Content-Type. Cheers.

[Dovecot] Mount options and NFS: just checking...
by Mike Brudenell 01 Aug '07

01 Aug '07

Greetings - I'm now in the last couple of weeks before going live with Dovecot (v1.0.3) on our revamped IMAP service. I'd like to double-check about the best mount options to use; could someone advise, please? I have three separate directory trees for the message store, the control files and the index files. These are arranged as follows: Message Store Mounted over NFS from a NetApp filer; filestore quotas are ENABLED. Control Files Mounted over NFS from the NetApp filer; filestore quotas are DISABLED. Index Files Mounted on local disk; filestore quotas are DISABLED. We will have a pair of Solaris 10 servers on which Dovecot 1.0.3 is running. Users are normally directed to their "preferred" server but, if it is unavailable, will go via the other server. Q1. Am I right in thinking that for the Message Store and Control Files I should NFS-mount both of them with the "actimeo=0"? (Or would "noac" be better, which also turns off client write- caching as well as the attribute cache?) Q2. Should I NFS-mount either or both of the Message Store and Control Files with the "noxattr" option to turn off extended attributes? Q3. Which of the filestores should I mount with the "noatime" option? (I understand that for the filer-based NFS mounts this can be done on the filer, as the option isn't available with "mount" for NFS-monted filestores.) Q4. Any other options to use/miss out? Currently my understanding from the list and the NFS page at the Wiki is: A1. Use "actimeo=0" for both Message Store and Control Files. No idea about the need for/impact of using "noac". A2. No idea. A3. Safe to use "noatime" for all three filestores. (I understand Dovecot will use utime() when needed on such filestores, but am not sure if it will work on the NFS-mounted filestores from the filer if access times are turned off at the filer end.) Any thoughts, please?

[Dovecot] mbox bug in 1.0.0
by bhayden＠umn.edu 01 Aug '07

Hi folks. We're moving users from rc24 and 27 to 1.0.0. On four mailboxes so far we've seen these errors after the move (quick and dirty anonymizing follows): Apr 23 13:22:41 server.umn.edu dovecot: [ID 107833 local6.info] imap-login: Login: user=<USER>, pid=<9046>, method=PLAIN, rip=***.***.***.***, lip=***.***.***.***, TLS Apr 23 13:22:41 server.umn.edu dovecot: [ID 107833 local6.error] [9073] IMAP(USER): mbox /var/mail/user: seq=1 uid=8808 uid_broken=0 originally needed 10 bytes, now needs 23 bytes Apr 23 13:22:41 server.umn.edu dovecot: [ID 107833 local6.error] [9073] IMAP(USER): Raw backtrace: 0x7b800 -> 0x43434 -> 0x3e018 -> 0x3fc34 -> 0x40080 -> 0x6d3cc -> 0x29a88 -> 0x21324 -> 0x214c0 -> 0x22f48 -> 0x22ec0 -> 0x230c0 -> 0x81c18 -> 0x814e4 -> 0x2b5cc -> 0x1dc58 Points of interest: 1. I can't reproduce this. It still happens after the user's .imap directories are removed. If I make a copy of the mailbox on another machine running the same version of Dovecot with the same config, the problem doesn't occur. Weird. 2. So far, have only seen it on quite large mailboxes (close to or over 100MB). Most large boxes have not had the problem, but the ones that have are all large. Any thoughts?

[Dovecot] dovecot-uidlist locking
by Tony Tsang 01 Aug '07

01 Aug '07

Hi all, I've a dovecot server setup and occassionally clients cannot get mails from their inbox. When I inspect the maildir for that user, there is stale dovecot-uidlist.lock file, and imap process keeps waiting for release of the lock. Is there any other method to perform locking on dovecot-uidlist instead of using dotlock mechanism? It is creating maintenance problems if I need to remove those stale lock files everytime clients hit this problem Tony.

[Dovecot] user name before and after authentication
by François Wautier 01 Aug '07

01 Aug '07

Hi, I am new to dovecot and spend the last few hours trying to configure it to my liking. I am using version 1.0.2 I have a setup where I only have "virtual" mailboxes in various domain ( mydomain.com, mydomain.biz,...). I setup Exim to deliver the email into <some path>/domains/<domainname>/<user> Now I am trying to get dovecot to access those mailboxes I setup LDAP bind authentication against an AD server. it works fine... but I have a problem getting the correct path to the mailboxes. The user logs in as user(a)domain.ext The mailbox path being at <some path>/domains/%n/%u The LDAP module gets the DN for my user and verify that it can binds, and in the process changes the "user" to cn=<real name>,cn=Users,dc=domain,dc=ext There goes my path To make matter worse, the uid and gid are the same for all users and are fixed (exim user and group). Hence cannot be retrieved from AD I tried to use userdb static, but I can't seem to be able to reset "user" to its pre-authentication value userdb prefetch/ldap but I can't set the uid/gid So here are my request for help... Is there a way to set home dir/ mail dir before authentication? Is there a way to reference the pre-auth user name? Is there a way to create arbitrary variables and used them? Is there a way to fix the uid/gid to use to access the mailboxes? Any one of these could probably solve my problem. Any suggestion is most welcome. François

[Dovecot] IMAPs and POP3s poxying
by Jason Russler 01 Aug '07

01 Aug '07

Hi All, I have a polotical situation at work that requires that I off-load mail access to a host other than the one our users have configured in their clients. I don't have access to any of the switching or routing to our hosts, and there's only a 1 to 1 relationship between the proxy I want to set up and the actual mail handler. I was looking at the proxying Howto in the Wiki and was presented with an SQL server requirement to do user/ip address look-ups. In my case, it will always be proxying the same host. How would I configure Dovecot to proxy another single system without doing the SQL look-up? Is there a port-forwarding solution that would work better (for POP3s and IMAPS)? These are RedHat 5 hosts so Netfilter is fair game if the protocols allow. Thanks, -Jason

[Dovecot] apparent bug with filesystem quota and message lists
by Stewart Dean 01 Aug '07

01 Aug '07

Don't know if anyone else uses Berkeley derived filesystem quota, but IBM's AIX does. A little over a week after migrating from UWIMAP to DC (with mbox format unchanged) everything is clean except for this one problem: When users go over quota, when they login the next time, the folder list is blank. You can imagine the panicked calls to the Helpdesk. If their quotas are raised or re-graced, Get Mail returns the expected list. This behavior happens with a variety of clients: Pine, MacMail,TBird, Horde Webmail, etc. The index filesystem has no quota on it. I would have to imagine the Dovecot is using (or trying to use) some space in the quota'ed filesystems which the operating system won't allow, and this results in there being an empty file that DC uses for the message list sent to the client. There are NO messages in syslog (other than the expected login and logout) indicating any problems. Our legacy setup has the inboxes in /var/spool/mail, and the folders in ~/mail. The problem can happen either place. dovecot -n returns: > # 1.0.1: /usr/local/etc/dovecot.conf > listen: *:143 > ssl_listen: *:993 > disable_plaintext_auth: no > login_dir: /var/run/dovecot/login > login_executable: /usr/local/libexec/dovecot/imap-login > login_processes_count: 12 > login_max_processes_count: 774 > verbose_proctitle: yes > first_valid_uid: 200 > mail_location: mbox:~/mail:INBOX=/var/spool/mail/%u:INDEX=/var/dcindx/%u > mbox_dirty_syncs: no > mbox_lazy_writes: no > auth default: > passdb: > driver: pam > userdb: > driver: passwd Suggestions? -- ==== Stewart Dean, Unix System Admin, Henderson Computer Resources Center of Bard College, Annandale-on-Hudson, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035

[Dovecot] Dovecot won't build against recent version of GnuTLS
by Jasper Bryant-Greene 01 Aug '07

01 Aug '07

Hi all, Dovecot won't build against recent versions of GnuTLS. The problem starts on line 34 of src/master/ssl-init-gnutls.c, where Dovecot generates DH params using gnutls_dh_params_generate(), a function which no longer exists [replaced with gnutls_dh_params_generate2()]. I'd fix it myself, but the signature of the function has changed to take gnutls_dh_params_t rather than prime & generator, and I'm not keen on hacking SSL code unless I really understand what's going on. It looks like the code goes on to save & free those values. I'm tracking HG and am happy to test any changes. Appreciate it if someone with more knowledge of GnuTLS and perhaps this code in particular could take a look. Thanks, J

It will not release the lock on the user mailbox and so mail to that user cannot be delivered. As a result the mailq backs up mostly with mail to that user. Closing the MUA does not help. I have to kill -9 PID the process to clear the hung connection. This happens with both Outlook and Thunderbird. Is there an option in the dovecot configuration that I can set to automatically close connections after say 30 minutes ? In the workaround section it says that it will close connections from Outlook & Outlook Express after 30 minutes dues to an IDLE bug in those 2. Regards, Arjun Datta

[Dovecot] Shared mailboxes (maildir, symlinks) and permissions
by Andreas Ntaflos 28 Jul '07

28 Jul '07

Hello list, I am trying to set up a public mailbox for users to put spam in so that sa-learn can do its job at night. Only I can't seem to fully understand how and which permissions should be set. I've read [1] and am using Dovecot 1.0.1. First some background information: I do not host or care (at the moment) about virtual users or virtual mail hosting. All users have Unix system accounts and shell access. I'd like to have a Spam folder, say /var/mail/public/.Spam that is a maildir where users can put Spam that got through the server-side filter. Spamassassin's sa-learn runs nightly and learns from the contents of the Spam folder. After reading [1] I think I should have under /var/mail/public a file called dovecot-shared that belongs to root:mail and has permissions 0660 (with user dovecot being a member of group mail) so that it looks like this: root@host:/var/mail/public# ls drwxr-sr-x 2 root mail 4096 2007-07-28 03:29 . drwxrwsr-x 3 root mail 4096 2007-07-28 02:19 .. -rw-rw---- 1 root mail 0 2007-07-28 02:46 dovecot-shared root@host:/var/mail/public# The first question arises: should Dovecot have write access to /var/mail/public itself? Now I should create the Spam folder called /var/mail/public/.Spam. Should this directory be in maildir format, i.e. should it already contain the subdirectories cur, tmp and new? What of the permissions of this directory? I am pretty sure Dovecot needs write access to it, so it should look like this: root@host:/var/mail/public# ls drwxr-sr-x 3 root mail 4096 2007-07-28 03:44 . drwxrwsr-x 3 root mail 4096 2007-07-28 02:19 .. -rw-rw---- 1 root mail 0 2007-07-28 02:46 dovecot-shared drwxrwsr-x 2 root mail 4096 2007-07-28 03:44 .Spam root@host:/var/mail/public# The .Spam directory here is completely empty. Now in a user's Maildir (/home/user1/Maildir) there are the user's private folders; a symlink to /var/mail/public/.Spam should be added: root@host:/home/user1/Maildir# ln -s /var/mail/public/.Spam . root@host:/home/user1/Maildir# ls ... drwx------ 5 user1 user1 4096 2007-07-19 16:14 .INBOX.foo drwx------ 5 user1 user1 4096 2007-07-06 23:01 .INBOX.bar ... lrwxrwxrwx 1 user1 user1 22 2007-07-28 03:51 .Spam -> /var/mail/public/.Spam ... root@host:/home/user1/Maildir# Is that all I have to do? Probably not, because I keep getting errors like the following when connecting (after subscribing of course): Jul 28 03:52:35 host dovecot: IMAP(user1): mkdir(/home/user1/Maildir/.Spam/cur) failed: Permission denied Should I have created the cur, tmp and new subdirectories manually and set their permissions like /var/mail/public/.Spam? But that still wouldn't give user1 write access. If I gave the users (or "others": chmod o+w) write permissions then Dovecot's index files would be owned by the first user that connects to the server and uses that folder. Apparently also not a solution. I also don't think I should have to make my users members of the mail group, but I could be wrong here. So I am not sure what I am missing, or if what I want to do is at all possible (without taking out the sledgehammer and setting all permissions to 0777). I also apologise for this lengthy post with many details and little interesting questions. It's getting late and I fear I've reached a dead end. I'd really appreciate it if someone knowledgeable could point me in the right direction here. Thanks in advance!

[Dovecot] Issues upgrading to 1.1alpha1
by Luca Corti 27 Jul '07

27 Jul '07

I'm trying to upgrade from 1.0.2 to 1.1alpha1. I can build and start dovecot correctly. dovecot -n says: # 1.1.alpha1: /usr/local/etc/dovecot.conf protocols: imap pop3 ssl_cert_file: /etc/postfix/server.pem ssl_key_file: /etc/postfix/server.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 mail_location: maildir:/mnt/shared/mail/%u:INDEX=/var/indexes/%u mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 auth default: passdb: driver: pam passdb: driver: passwd userdb: driver: passwd socket: type: listen client: path: /usr/local/var/run/dovecot/auth-client mode: 436 master: path: /usr/local/var/run/dovecot/auth-master mode: 384 user: root group: dovecot When I try to access my 1.4G Maildir via IMAP I can see messages in INBOX, but accessing mail in other folders returns a "resource temporarily unavailable" error in my client. In the server logs I see killed by signal 10 errors for dovecot imap processes. I'm on Linux 2.6.21 sparc64, mail is stored in NFS, indexes on local disk. ciao Luca

[Dovecot] auth_cache_...
by Frank Elsner 26 Jul '07

26 Jul '07

Hello, the dovecot-example.conf states: # Authentication cache size in kilobytes. 0 means it's disabled. # Note that bsdauth, PAM and vpopmail require cache_key to be set for caching # to be used. #auth_cache_size = 0 # Time to live in seconds for cached data. After this many seconds the cached # record is no longer used, *except* if the main database lookup returns # internal failure. We also try to handle password changes automatically: If # user's previous authentication was successful, but this one wasn't, the # cache isn't used. For now this works only with plaintext authentication. #auth_cache_ttl = 3600 auth_cache_size = 0, does it mean "cache can grow ad infinitum" or does it mean "no cache at all" ?

[Dovecot] quota: maildrop + dovecot. dovecot doesn't update maildirsize file
by Frittella Laurento 26 Jul '07

26 Jul '07

Hi all, I'm trying to implement quota support in postfix using maildrop + dovecot but I think dovecot doesn't update info stored in maildirsize file. # 1.0.2: /etc/dovecot/dovecot.conf base_dir: /var/run/dovecot/ listen: 127.0.0.1 ssl_listen: * ssl_ca_file: ... ssl_cert_file: ... ssl_key_file: ... ssl_cipher_list: ALL:!LOW:!SSLv2 login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login valid_chroot_dirs: /home/vmail/domains first_valid_uid: 1001 last_valid_uid: 1001 first_valid_gid: 1001 last_valid_gid: 1001 mail_location: maildir:/home/vmail/domains/%d/%n auth default: user: dovecot-auth passdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf userdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf plugin: quota: maildir:ignore=Trash When a mail arrives maildrop delivers it and update info in the maildirsize file, but when I delete messages through dovecot (using thunderbird) the maildirsize remains the same and so users reach overquota very soon. What's wrong? Thanks in advance, Laurento

[Dovecot] dspam plugin
by Oliver Kohll 26 Jul '07

26 Jul '07

Hello, I'm trying to install the dspam plugin to dovecot. So far, I've Installed dovecot 1.0.2 from RPM and set up Installed dspam 3.8.0, set up and integrated with postfix, using dspam as local delivery agent before dovecot's deliver Downloaded the dovecot 1.0.2 source in order to compile the C file http://johannes.sipsolutions.net/Projects/dovecot-dspam-integration/ beta7-code with the command cc -fPIC -shared -Wall -I../src/ -I../src/lib -I.. -I../src/lib- storage -I../src/lib-mail -I../src/lib-imap -I../src/imap/ - DHAVE_CONFIG_H -DDSPAM=\"/usr/local/bin/dspam\" dspam.c -o lib_dspam.so and copied the resulting lib_dspam.so to /usr/lib/dovecot/imap/ In dovecot.conf, set protocol imap { mail_plugins = dspam mail_plugin_dir = /usr/lib/dovecot/imap } Created a SPAM folder. However, when I move a message into or out of the SPAM folder, dspam doesn't seem to execute. Nothing appears in /usr/local/var/dspam/system.log or /var/log/maillog and "SELECT * FROM dspam_stats;" in the dspam database returns unchanged numbers: dspam=> select * from dspam_stats ; uid | spam_learned | innocent_learned | spam_misclassified | innocent_misclassified | spam_corpusfed | innocent_corpusfed | spam_classified | innocent_classified -----+--------------+------------------+-------------------- +------------------------+----------------+-------------------- +-----------------+--------------------- 505 | 18 | 1870 | 3 | 3 | 0 | 3 | 0 | 0 (1 row) One thing that may be relevant is that I have a namespace in dovecot.conf namespace private { prefix = INBOX. inbox = yes } Any ideas? Regards Oliver p.s. the page http://johannes.sipsolutions.net/Projects/dovecot-dspam- integration seems to be blank now but the Google cache http:// 216.239.59.104/search?q=cache:K_yW5wV88uwJ:johannes.sipsolutions.net/ Projects/dovecot-dspam-integration+dovecot +dspam&hl=en&ct=clnk&cd=3&client=safari is still there for now. oliver(a)gtwm.co.uk / 0845 456 1810 / 07814 828608 The Old Bank, 4 Ravenhill Rd, Swansea SA5 5AW, UK NOTE No contracts may be concluded on behalf of GT webMarque by means of e- mail communications.

[Dovecot] Vacation message functionality
by Charles Marcus 25 Jul '07

25 Jul '07

Hi, Since I will soon be attempting to get this working on one of my client's systems, I posed a question on the postfix list - since they mostly dislike vacation messages - but *ardent haters* of badly configured vacation message systems - as to the quality of the dovecot vacation message function. The only response I got did seem to have a few very good suggestions for additional conditions to test for, so I'm posting the response here to see if they can be incorporated (I'm not a coder or I'd attempt it myself). The original text (prefixed by double quote characters) in the following exchange is what I copied/pasted from the wiki, and the reply (prefixed by one quote character) is the suggested change/enhancement (this reply is from a trusted source on the postfix list): >> Vacation auto-reply >> >> The vacation replies are sent to the envelope sender. Currently this >> is taken from the Return-Path: header in the message. > comment: > or from the command line if this is supported. > > also, if the envelope sender is not available, no reply should be > sent. >> List of autoreplied senders is stored in .dovecot.lda-dupes file in >> user's home directory. When you're testing the vacation feature, it's >> easy to forget that the reply is sent only once in the number of >> configured days. If you've problems getting the vacation reply, try >> deleting this file. If that didn't help, make sure the problem isn't >> related to sending mails in general by trying the "reject" Sieve >> command. > if you support extensions, you can test using a unique sender each > time: foo+12345(a)domain.example. >> The automatic replies aren't sent if any of the following is true: >> >> <snip> >> >> o begins with "owner-" (case-sensitive) > replace with: > o starts with "${token}-" (not case sensitive), where token > is one of: owner, request, bounces > > It is safer to send nothing than send a risky one. >> o contains the string "-request" anywhere within it >> (case-sensitive) > replace with: > o contains "-${token}@" (not case sensitive), where token is > one of: owner, request, bounces >> * The envelope sender and envelope recipient are the same >> * The envelope recipient is not found in the message To:, Cc: or >> Bcc: fields. > add: > * There is a "Sender:" header containing one of the tokens listed > above. > * There is a List-Id or List-Post header > * There is no header suggesting that this is possible spam > > Unlike delivery, safety here is to not send a reply if the message > may be spam. so you don't rely on recipient preferences, and you > don't fear false positives too much (the guy who receives your > auto-rep may have a better filter, and besides annoying him, would > find you stupid to miss an obvious spam ;-p) >> The envelope sender is taken from a Return-Path: header in the >> message. The envelope recipient is taken from the recipient user >> (-d parameter with virtual user setup). A bare username without a >> domain gets canonicalised by the libsieve code to >> "<username>@unspecified-domain", which means it is highly unlikely >> to pass the last two tests in the list above. > note: > the envelope recipient can also be retrieved in the Delivered-To > header if this is available ('D' flag). Comments appreciated... -- Best regards, Charles
