[Dovecot] imap+ssl feedback
by Herr Nagengast 15 Aug '06

15 Aug '06

I've been using 1.0rc5 since August 2nd. Thunderbird users on multiple platforms haven't had any problems saving messages to the Sent mailbox. I know from reading release notes that the SSL proxy code in rc5 is different from rc6, but I have to admit to being leery about upgrading since it works for me. Here's my configure command: ./configure --without-shadow --localstatedir=/var --with-notify=kqueue --with-cyrus-sasl2 --without-gssapi --without-vpopmail --prefix=/usr/local --build=i386-portbld-freebsd5.3 Thanks for your hard work!

[Dovecot] Possible to alias ("ln") a folder?
by scianos＠speakeasy.net 15 Aug '06

15 Aug '06

Greetings - I've got an interesting issue that has cropped up due to some brain-dead "functionality" in mobile Windows Mobile clients... Our mail infrastructure traditionally uses "Sent" as our sent items folder. This is the default. However, WM puts it's sent messages in a folder called "Sent Items", and does not let you change it. Is there any proper and/or elegant way to alias the Sent folder to Sent Items (and allow both to coexist as the same message store) in an automated fashion without needing to set this up for each user? Thank you in advance for you help and patience! - Stu

[Dovecot] dovecot tring to load sql modules
by Dean Gibson (Mail Administrator) 15 Aug '06

Dovecot is issuing: Aug 12 17:09:27 athlon1 dovecot: Dovecot v1.0.rc6 starting up Aug 12 17:09:27 athlon1 dovecot: Generating Diffie-Hellman parameters for the first time. This may take a while..

The RPM requires the above SQL library module, among others (inc. postgresql and sqlite). However: 1. Why do I need ANY SQL library??? I want PAM to do the authorization. 2. If I have to use SQL, I want Dovecot to use PostgreSQL (which I have installed and am using in another application). I hope the above is a dumb question, because that means the fix is easy. No, I'd rather not build my own; that's why I picked an RPM. Running Fedora Core 1. -- Dean

[Dovecot] dovecot-lda, sieve, maildir
by Frank Cusack 14 Aug '06

I'm unable to get dovecot-lda with sieve filtering to deliver into maildir folders. The examples on the wiki explicitly say "mbox", so I'm wondering, does the dovecot-lda sieve implementation not support filtering into maildir folders? -frank

[Dovecot] duplicate uids in Outlook
by Faisal Shaikh 14 Aug '06

14 Aug '06

Hi, I run a Postfix/Dovecot server with Outlook 2002, Thunderbird clients as well as a Squirrelmail setup. All use IMAP to query the server. I recently converted our mail spool from mbox to maildir. After the conversion, one of the users is receiving two types of error messages which appear in a popup window. 1. The first popup says the following The UI D of a message changed unexpectedly. This typically indicates a server bug. Your program may not function properly after this. It then gives details of the MsgSeqNum, old UID and the new UID. 2. The second popup says Your server has reported a UID which does not comply with the IMAP standard. This typically indicates a server bug. Your program may not function properly after this. Ive searched for this on google and it has been reported before, but there are no reports of a solution or workaround. I would really appreciate any pointers or suggestions. Many Thanks, Faisal Shaikh

[Dovecot] POP to IMAP Transition
by Yudhvir Singh Sidhu 14 Aug '06

14 Aug '06

I am using Dovecot IMAP and added an IMAP folder to an Outlook client which is also popping another account. Both account folders exist in the same client. I am wondering if I can drag the pop-ed mail to the IMAP folder, thereby transferring old mail to the IMAP folder? Outlook allows me to click and drag folders into the IMAP folder. You see where I am going with this, I wnat to transition from the old POP accounts to the new IMAP accounts and delete the old folders. Is this possible? I'd love to hear from someone who has done this. ======== Yudhvir Singh Sidhu Systems Administrator Industry-University Cooperative Research Program www.ucdiscoverygrant.org 2087 Addison Street, 2nd Floor Berkeley, CA 94720-3340 510 643 4039 fax 510 643 7839

[Dovecot] Dovecot fails to come up when using ACLs (1.0.b5)

Suggestion for comments. Why not support this syntax for comments as well as # /* comments comments */ It will allow for neater looking config files.

[Dovecot] Ignoring dot files

Hi, Is there any way to have dovecot ignore files begining with . in directories that contain mbox formatted mail folders (in addition to the already ignored .imap and .subscriptions)? I've looked in the docs and haven't found anything but perhaps I'm not looking in the right place. Thanks, Andrew

[Dovecot] rc6 + ssl proxy patch = no go

Timo, I nervously ran rc6 plus the patch: http://dovecot.org/tmp/ssl-proxy-openssl.c on my Solaris 9 box, in production, this morning. My dovecot.conf file is attached. Like similar reports for BSD, rc6 fell over after an hour and a half. The final syslog message was: dovecot: [ID 920869 mail.error] Login process died too early - shutting down I rolled back to rc2 for production. BTW, last night's CVS compiled ok.

[Dovecot] IMAP4rev1 broken with evolution
by Charles Bueche 11 Aug '06

11 Aug '06

Hi, I'm running 1.0rc6 on Solaris/SPARC, compiled myself against openssl. Client is Evolution 2.6.2 on my gentoo x86 laptop. As Dovecot is not yet productive, we run it parallel to UW-imap, on other ports. I use TLS. If I configure my evolution client with server-type IMAP, everything works fine. However, dovecot claims IMAP4rev1 support. However, when I set server-type to IMAP4rev1 in evolution, I get a popup : -------------------------------------------------------------------- Evolution popup : Error while Scanning folders in "IMAP server xxx.yyy.com". IMAP4 server xxx.yyy.com unexpectedly disconnected : Invalid argument -------------------------------------------------------------------- Using --debug with evolution doesn't show more. In dovecot logs, nothing interesting. I'm ready to test, so please hints me. TIA, Charles -- Charles Bueche <charles(a)bueche.ch> sand, snow, wave, wind and net -surfer

[Dovecot] Summerising users subfolders imap logs?

But as I cant see here which subfolder the user access, so is it possible to summerise somehow this per users mass logging witth one row, something like: imap-login: Login: anti, [192.168.20.1], PLAIN, TLS, accessed 100 folders, or just: imap-login: Login: anti, [192.168.20.1], PLAIN, TLS Or someting else? Any idea to make this happend? -- Sysadmin

[Dovecot] vacation messages (dovecot lda cmusieve)
by Rene Luria 11 Aug '06

11 Aug '06

Hi, I am experiencing some problems with vacation messages feature. Using dovecot from alpha4 to 1.0.rc6 with lda from cvs, when setting up a vacation message, there is a parameter ":days" which specifies the interval between auto-reply messages. After the first reply, should wait that amount of days before sending a new reply to the same sender. The list of sender addresses is to be kept in $maildir/.dovecot.lda-dupes Now, what happens is that at random intervals, auto-replies are sent. It happens with any account, from thirty minutes to one hour maybe. How is it possible ? How to fix it ?

Does something still use SSLv2? If I do the change, I guess the only thing it does is to break those clients that still try to use it? Is its security already bad enough that it's just better to break them?

[Dovecot] SSL CRL checking
by Timo Sirainen 11 Aug '06

11 Aug '06

Is there a reason that CRL is required to exist in the ssl_ca_file? Could it just use it only if it's there, but otherwise ignore it? Or is this a bad idea? Is it even possible at all to tell that to OpenSSL?

[Dovecot] Seeing dovecot crash under rc6, seems to go almost exactly every 2.5 hours...

We're getting the following crash report, but I'm not sure it contains anything immediately useful (especially since we're running on a minority platform in OS X)...

[Dovecot] LDA Command time limit exceeded
by Dominique Feyer 11 Aug '06

I have many errors of this type in my logs: 2 * postfix/pipe[21511]: BC8DD3356A: to=<*****@******>, relay=dovecot, delay=1001, status=bounced (Command time limit exceeded: "/usr/local/dovecot-1.0-rc2/libexec/dovecot/deliver") My command time limit is 1000s in postfix (more than 15 minutes) After many check, I found that a lots of this error is not really an error. The mail is delivered in the mailbox, but postfix send an error message. Like if Dovecot LDA process dont exit correctly after sending a mail. Do you know this bug ? As workaround i set the command time limit to 1400s but this is too long for our customer. They need in time service. We use an NFS server as storage for all our mail.

[Dovecot] xfs quota support

Hello, quota support is out of action on xfs filesystem on my centos 4.x . Problem is that i haven't these file #include <linux/dqblk_xfs.h> on my system. Solution is simple. After instalation xfsprogs-devel you get necessary files, but you must use another header file in dovecot/src/plugins/quota/quota-fs.c. Instead <linux/dqblk_xfs.h> you should use <xfs/xqm.h>. If you advise me, how can i detect if <xfs/xqm.h> exist instead <linux/dqblk_xfs.h>, i can send patch back. I'm not familiar with autotools. existing code in dovecot/src/plugins/quota/quota-fs.c : #ifdef HAVE_LINUX_DQBLK_XFS_H # include <linux/dqblk_xfs.h> #endif new code : #ifdef HAVE_XFS_XQM_H #include<xfs/xqm.h> #endif Best regards Polish -- ********************************************************** * starnem a porad nic, rozum jako kdyby se nam vyhybal * **********************************************************

[Dovecot] Error: imap-login: Can't connect to auth server at default: Resource temporarily unavailable

So I just upgraded from Dovecot 0.99 to the latest 1.0 RC2 because I was having all sorts of Authentication problems and crashes in 0.99. The upgrade did not solve the problem apparently.

Currently only the dovecot server talks to the maildirs. Postfix is also on this server, using the same PAM Authentication for SASL and works fine - It does not appear to be a problem with the Authentication server. Thanks in advance!!! -Matt

Re: [Dovecot] Dovecot deliver logging problem and procmail
by Gerhard Wiesinger 11 Aug '06

11 Aug '06

Hello Timo! Any ideas why it may take so long time to open big mbox files with indexes and delivered through dovecot deliver? So it looks like that something is wrong with the indexes or the algorithm. For details have a look below. BTW: procmail filtering through deliver works well now for me in production environment. I'll make some code cleanups and configuration options. Maybe I can release the patch today.

I tried to deliver some large mails (~50MB) which worked well. After sending around 500MB (10 Mails) I opened the mailbox with pine over imap. It still took a lot of time (>20s) to open the mbox. Indexes should be up2date, so why does it take so long time? After opening a second time everything is fine. Any ideas? Ciao, Gerhard

[Dovecot] 1.0.rc2 released
by Timo Sirainen 11 Aug '06

11 Aug '06

Final 1.0 release is looking to get closer. There's nothing left in my TODO list for it, so please report any old and new bugs you see. This release also makes upgrades from 0.99 more transparent with automatic renaming of .subscriptions and .customflags files with maildir. http://dovecot.org/releases/dovecot-1.0.rc2.tar.gz http://dovecot.org/releases/dovecot-1.0.rc2.tar.gz.sig * disable_plaintext_auth=yes: Removed hardcoded 127.* and ::1 IP checks. Now we just assume that the connection is secure if the local IP matches the remote IP address. * SSL code rewrite which hopefully makes it work better than before. Seems to work correctly, but if you suddently have trouble with SSL connections this is likely the reason. + verbose_ssl=yes: Log also SSL alerts and BIO errors - If namespace's location field wasn't set, the default location was supposed to be used but it wasn't. - When copying ssl-parameters.dat file from /var/lib to /var/run its permissions went wrong if it couldn't be copied with hard linking. - Fixed filesystem quota plugin to work with BSDs. - Maildir: Saving mails didn't work if quota plugin was enabled (again) - Maildir: Messages' received time wasn't saved properly when saving/copying multiple messages at a time. Also if using quota plugin the S= size was only set for the first saved file, and even that was wrong. - passdb passwd-file: Don't require valid uid/gid fields if file isn't also being used as a userdb. - PostgreSQL: Handle failures better so that there won't be "invalid fd" errors in logs. - Don't try to expunge messages if the mailbox is read-only. It'll just cause our index files to go out of sync with the real mailbox and cause errors. - ANONYMOUS authentication mechanism couldn't work because anonymous_username setting wasn't passed from master process.

[Dovecot] imap-login (proxy) Connection queue full
by Bill Boebel 11 Aug '06

11 Aug '06

When running Dovecot (rc6 CVS dovecot-20060808) as a proxy, why would it log the following when it has not yet maxed out the allowed number of imap-login processes? Aug 10 16:23:34 director5 dovecot: imap-login: Disconnected: Connection queue full: I am seeing this logged several times per minute. From netstat, the server has 650 proxied IMAP connections and 450 proxied IMAPS connections, there are currently 10 imap-login processes running, and using the following config: login_process_per_connection = no login_processes_count = 3 login_max_processes_count = 20 login_max_connections = 225 I would think that under these conditions we should never see "Connection queue full" being logged. Thanks, Bill

[Dovecot] maildir++ specification compliance.
by Apps Lists 10 Aug '06

10 Aug '06

Hi folks. I was doing some testing this morning and realized Dovecot RC2 isn't fully compliant with the maildir++ specification. Most notably, it appears that Dovecot isn't creating a "maildirfolder" file (0 byte length) in folders it creates. >From http://www.inter7.com/courierimap/README.maildirquota.html "Within each subdirectory there's an empty file, maildirfolder. Its existence tells the mail delivery agent that this Maildir is a really a folder underneath a parent Maildir++." and "Make sure to create the maildirfolder file in any new folders created within the Maildir++." Also, GETQUOTAROOT on a folder (with messages in it) will always return the entire usage, not the usage in the folder itself. For example: INBOX - really has 100 mb of messages. Sent - has a few messages totalling 1mb. Drafts - no messages A GETQUOTAROOT on INBOX will return 101 mb, 100mb for INBOX and 1mb for Sent. Drafts will show zero, because there's nothing. Unfortunately, Sent will also show 101 mb, not 1mb. While Dovecot shouldn't be creating maildirsize files in each folder (the maildirfolder file is there to tell clients to look in .. for a maildirsize) ... it should still be able to answer queries about the number of messages (count of files in the folder) as well as the total size of all messages in that folder (sum of S=xxxx or by stat() on individual message files).

[Dovecot] Developing new Dspam Plugin
by Timothy White 10 Aug '06

10 Aug '06

This email /was/ going to be a bit of a bitch about trying to get mysql compiled in to a dovecot plugin, but I got it all working before I finished the email! :-D Ok, basically what I am doing (Johannes permission) is modifying the dspam plugin, so that it instead talks to a database (MySQL in this case), and updates a table, so that you can do the actual training at a time of lower load. It /does/ require MySQL >= 5 cause I am using stored PROCEDURE's, which gives you the advantage, that you can use the same plugin, without changing anything, regardless of what your database looks like, or how you want the database to work! :-D I have successfully modified Johannes plugin to call SPAM and HAM in the database, with the signatures, and also upgraded it to work with beta9. I also made the small change of a define for the Spam folder, so that if your Spam folder is named differently, you don't have to change the code in 2-3 places as well ;-) I am yet to write any 'batch' code for processing the database tables, but that is fairly trivial, and I could even write it in php if I wanted ;-) (If you want something to do, go ahead and write me a C client to do this!

[Dovecot] Complex MySQL query in dovecot-sql.conf
by Timo Neuvonen 10 Aug '06

10 Aug '06

Is there some limit for the maximum length of the line in dovecot-sql.conf? In particular, I would be writing a long MySQL password query. And further, can a long line be somehow split to several pieces? I tried the common unix-style way of putting backslash as the last character of the first line, but it results in an error immediatedly while restarting Dovecot (while parsing the conf, ie. not a MySQL error): (in conf:) password_query = SELECT user, password FROM users\ WHERE user='%u' AND active='Y' (results in log, line 88 refers to line starting with 'WHERE':) auth(default): Error in configuration file /etc/dovecot-mysql.conf line 88: Expecting '=' The example above is just the beginning, what comes to my question about a long line. I would be checking %r (remote ip) against user-specific allowed ip-address ranges given in the database. Actually, I'd like to use some MySQL user-defined variables within my query, for example to keep only the 3 highest octets of the IPv4 representation of %r (eg. '192.168.0') so I could easily check against allowed /24 networks stored in the database. That seems to run into another problem. A very simplified example what happens when I try to define a variable within the query: (in conf, split to two lines for news only:) password_query = SET @yes='Y'; SELECT user, password FROM users WHERE user='%u' AND active=@yes (results in log:) Password query failed: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '; SELECT user, password FROM users WHERE user='testi' AND active=@yes' at line 1 Anyway, a similar one-line construct works from the MySQL command line: SET @yes='Y'; SELECT user, password FROM users WHERE user='testi' AND active=@yes; (reults the following:) +-------+----------+ | user | password | +-------+----------+ | testi | 123 | +-------+----------+ Any ideas? Am I doing something in a completely wrong way? Of course, split lines & variables are not absolutely necessary, they just would improve readability & shorten the query. But if there is no limit on the length of the query, I propably can write everything as a one long SELECT command... I'm trying all this on Fedora Core 5, having - dovecot-1.0-0.beta8.2.fc5 - mysql-5.0.22-1.FC5.1 Regards, Timo Neuvonen

[Dovecot] My view on 1.0 release and version numbering
by Marc Perkel 10 Aug '06

10 Aug '06

Just throwing out some thoughts here. I know Timo has high standards and is trying to make 1.0 bug free before calling it 1.0. But I want to argue for an earlier less perfect 1.0. Dovecot is already way past the quality of most 1.0 releases. So it is good enough by common standards. No one really expects a 1.0 release to be perfect. But - some people don't consider a product ripe until it reaches 1.0. Once you cross the line then more people will pick it up and you will get more bug reports because of a larger base. This would actually accelerate the debugging process. And it will spur acceptance of the product and perhaps bring in more developer resources. Generally 1.0 is still buggy. It is usually followed quickly with 1.0.1, 1.0.2 ... and then stabilizes. Then as more people ask for new features it spawns 1.1.0 which is somewhat buggy and then 1.1.1 and by 1.1.2 it's rock solid. So - I'm not suggesting Timo go to 1.0 immediately. I'm just saying that I think it's pretty ripe and sooner is better than later. My 2 centz ...

[Dovecot] Dovecot under daemontools
by dale gallagher 10 Aug '06

10 Aug '06

Hi there I'm having difficulties in getting dovecot to run under daemontools. Also, from a sysadmin perspective, so far, I find dovecot's config rather complex - I suppose that's what happens when one attempts to appease all authentication methods... anyway, I digress. System details, to set the scene: OS: Slackware Linux Linux Kernel: 2.4.29 GCC: 3.2.2 Dovecot version: 1.0.rc6 Dovecot configure options: ./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var --with-checkpassword --without-passwd --without-passwd-file --without-shadow --without-pam --without-bsdauth --without-gssapi --without-ldap --without-vpopmail --with-prefetch-userdb --without-sql --without-pgsql --without-mysql --with-ssl=openssl --without-pop3d --with-storages=maildir --without-deliver MTA: qmail Storage: Maildirs under a single virtual user (vmail) Checkpassword: /var/qmail/bin/qmail-vpoplogin (modified cdb checkpassword) User DB: /var/qmail/users/vpasswd.cdb /etc/dovecot.conf base_dir = /var/run/dovecot protocols = imap listen = 127.0.0.1 ssl_disable = yes shutdown_clients = yes log_path = /var/log/dovecot login_dir = /var/run/dovecot/login maildir_copy_with_hardlinks = yes protocol imap { # only require access from webmail on same host listen = 127.0.0.1:143 } auth default { passdb checkpassword { args = /var/qmail/bin/qmail-vpoplogin } userdb prefetch { } # user who can access user/passwd db user = auth } Firstly, I cannot run dovecot as an unprivileged user, as the OS moans that the user doesn't have permission to write to /dev/stderr. I've had a similar issue running Clamav, but a patch to Clamav resolved this? This seems to be related to referencing /dev/stderr directly. Any ideas? Should I be running dovecot as the virtual mailbox user vmail? Before I ramble on about what I've tried, could someone explain to me what dovecot actually does, in terms of privilege separation? The online docs are somewhat convoluted. This would help shed light on the solution. I also noticed the posts re daemontools some time ago, yet they do not include any setup solutions etc - I'd appreciate details from those of you who've succeeded in this regard. Thanks Dale

[Dovecot] userdb prefetch problem..
by Mike 10 Aug '06

10 Aug '06

I have a setup that I'm working on migrating to Dovecot for thousands of users across a few dozen domains.. All users are authed from LDAP.. In LDAP, each user has a unique uidNumber, and varying gidNumber (for use in other applications) As far as mail storage, the entire Maildir structure is owned by UID/GID: vmail/vmail So, the uidNumber/gidNumber from LDAP is not needed. global uid/gid is set to 'vmail' When using "passdb ldap" and "userdb ldap" both pointing to dovecot-ldap.conf, and removing the "uidNumber=uid"..etc from the "_attrs" lines, this works just fine. I would like to use "userdb prefetch" to use one less ldap query, but the uid/gid stuff is giving me some problems. The appropriate line in - dovecot-ldap.conf: pass_attrs = mail=user,userPassword=password,homeDirectory=userdb_home I get the following erros in the log: .... .... dovecot: auth(default): prefetch(user(a)domain.com,127.0.0.1): userdb_uid not returned dovecot: auth(default): prefetch(user(a)domain.com,127.0.0.1): userdb_gid not returned dovecot: auth(default): userdb(user(a)domain.com,127.0.0.1): user not found from userdb dovecot: auth(default): master out: NOTFOUND 1 dovecot: pop3-login: Internal login failure: user=<user(a)domain.com>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Any help is appreciated! -Mike FreeBSD 6-1-RELEASE OpenLDAP 2.3 Dovecot 1.0rc2

[Dovecot] 1.0 RC1 status
by Timo Sirainen 10 Aug '06

10 Aug '06

Today I finally caught up with my mail. I've now read all the mails from the Dovecot list from this year and all my private mails from last few years (totaling around 500 unread mails). If you think there's still something I should have replied to, please re-send it because I've either missed it or just skipped it for some reason. (Except there are still a couple of mails from this week I've yet to reply to.) Besides reading mails I've also fixed a lot of bugs today. What's left from my original 1.0 roadmap is: - Solaris sendfile is broken? Is it? Can someone try? You can test it with maildir by setting mail_save_crlf=yes, saving a somewhat large mail and FETCHing it (and truss that it really uses sendfile) - LDA: empty mail gives an error. - quota code should probably be always doing some quota_set_critical() instead of using mail_storage_set_critical(), so that quota_last_error() would work properly - rfc2557 support for BODYSTRUCTURE, as specified by RFC3501 - keywords: add some limits to how many there can be - don't return \* in PERMANENTFLAGS when we're full - mbox: how well does dirty sync + status work? it reads the last mail every time? not very good.. - mbox: dirty state should be stored to index (with mbox_very_dirty_syncs) I think 1.0 could be released without any of those changes. But what about the connection hangs that some people have had? Do they still occur? Is it only with SSL? I guess I should look at my previous ssl-proxy rewrite, figure out what went wrong with it and try again. I'm thinking about releasing 1.0 RC1 within a few days. Would be nice if that release actually worked, so testing would be appreciated :) You can try it by getting the dovecot-latest from http://dovecot.org/nightly/ The current changes include: * PAM: If user's password is expired, give "Password expired" error message to the user. Now actually working thanks to Vaidas Pilkauskas * Relicensed dovecot-auth, lib-sql and lib-ntlm to MIT license. See COPYING file for more information. * Abuse prevention: When creating a mailbox, limit the number of hierarchies (up to 20) and the length of the mailbox name within a hierarchy (up to 200 characters). * mbox: If saved mail doesn't end with LF, add it ourself so that the mails always have one empty line before the next From-line. + Added --with-statedir configure option which defaults to $localstatedir/lib/dovecot. ssl-parameters.dat is permanently stored in that directory and is copied to login_dirs from there. + IMAP: Support SASL-IR extension (SASL initial response) + Support initial SASL response with LOGIN mechanism. Patch by Anders Karlsson + Added PLAIN-MD4 password scheme. Patch by Andrey Panin. + Added support for XFS disk quotas. Patch by Pawel Jarosz + If another process deletes the opened mailbox, try to handle it without writing errors to log file. Handles the most common cases. + Added TLS support for LDAP if the library supports it. - Dovecot corrupted mbox files which had CR+LF linefeeds in headers - MySQL code could have crashed while escaping strings - MD4 code with NTLM authentication was broken with 64bit systems. Patch by Andrey Panin - Plugin loading was broken in some OSes (eg. FreeBSD) - Several fixes to handling empty values in configuration file - Several fixes to dictionary quota backend and dict server. Also changed how they're configured. - deliver: Fixed plugin handling settings - mbox_min_index_size handling was somewhat broken - passdb passwd-file: extra_args field wasn't read unless the file was also used as userdb.

[Dovecot] Dovecot and MySQL auth - initial setup issues
by Andrew Hearn 10 Aug '06

10 Aug '06

Hello, I'm just setting up a new server and wanting to use MySQL for user authentication. Here is what I have: Fedora Core 5: 2.6.17-1.2145_FC5 Dovecot v1.0.rc2 (RPM install from atrpms.net) MySQL v5.0.22 SquirrelMail v 1.4.6-7.fc5 ...Running on a Dual XEON machine I've added the following to dovecot.conf: auth default { passdb sql { args = /etc/dovecot-mysql.conf } userdb sql { args = /etc/dovecot-mysql.conf } The rest of dovecot.conf is standard. /etc/dovecot-mysql.conf has: driver=mysql connect = host=127.0.0.1 port=3306 dbname=maildb user=root client_flags=0 password_query = SELECT password FROM users WHERE id = '%u' user_query = SELECT maildir FROM users WHERE id = '%u' (I've run the SQL queries within mysql and they give the right results) When I start Dovecot the log shows: dovecot: Jul 11 12:47:25 Info: Dovecot v1.0.rc2 starting up dovecot: Jul 11 12:47:27 Info: auth-worker(default): mysql: Connected to 127.0.0.1 (maildb) When I try to log in using SquirrelMail, it takes about 3 seconds, then I get dovecot: Jul 11 12:48:00 Info: imap-login: Aborted login: user=<andrew(a)mail-test.aaisp.net.uk>, method=PLAIN, rip=::ffff:127.0.0.1, lip=::ffff:127.0.0.1, secured ...So, no log of it trying MySQL...

[Dovecot] no protocols inhibits dovecot --exec-mail

10 Aug '06

Hi, Running the current debian unstable version (1.0.beta2) dovecot tells me: $ /usr/sbin/dovecot --exec-mail imap Error: No protocols given in configuration file Could this be changed? I don't need dovecot listening on any ports but would still like to allow this usage... Or should I configure protocols but no listen addresses instead? [if so the debian package needs an update because it filters out the case of no protocols and doesn't start dovecot in that case] johannes

[Dovecot] Duplicate e-mails
by Lisa Wu 10 Aug '06

10 Aug '06

Hi, I've got Postfix/Dovecot config mail server, POP3/mbox, and a few users are complaining about duplicate e-mails. User connects with Outlook 2003 to Dovecot to download mail. If you check the mail logs for that message ID, only one copy is delivered to his mailbox. Also, verified that the client is set-up to NOT leave a copy of the message on the server. He downloads a copy of the e-mail once, and then 2 minutes later when his client reconnects to check for mail, he gets another copy of that e-mail. It's not a consistent problem. I check the dovecot logs, and see his client connecting and disconnecting, and always deleting the same number of e-mails it downloads. Is this a network issue or a config issue? The only other thing to note is that it's usually an e-mail sent to a group list that he's a member of. And I've set-up the owner-list setting in the aliases file. So I don't think that's the problem. If anyone can shed some light on this issue, it'd be greatly appreciated. Thanks, Lisa

[Dovecot] Something other than dotlock for uidlist locking?

If I read the code correctly, only dotlocks are supported for locking of dovecot-uidlist. And I don't see any settings in the config file for it. As it turns out, dotlocks are very slow on my system, due to their implementation via hardlinks. Would it be possible to support other locking mechanisms for locking of the uidlist file? -jdb

[Dovecot] Newbie Questration
by Yudhvir Singh Sidhu 10 Aug '06

10 Aug '06

Actually, it is a frustration: The client does not work, have tried Opera mail and Outlook, to receive mail. the client can send, but not receive. I know the mail is sitting in the user account Maildir ready to be picked up. Dovecot "compiles" fine. What am I doing wrong? Someone please help me, I know it is something simple. I have racked the net trying to find a solution, but no 2 mail setups are the same. My setup is the simplest I can make it. I have Postfix and Dovecot installed on Linux. All recent versions. Plain text authentication off shadow passwords and login user accounts. Mail is configured as Maildir, IMAP. As you can see below, I have turned logs on and there is nothing in them that shows an error. I am on a real static IP behind a firewall. I have opened the SMTP and IMAP ports. BTW, Postfix can send and receive local and outside. IMAP does not work to/fro outside or locally. I have also logged into Dovecot like so: telnet localhost imap 1 login test testing 2 select INBOX It lets me login and I have tried it with root, which it rejects and with another account which works. It selects the INBOX and I hit the return key multiple times to exit because I don't know what else to type. So, it looks like it is authenticating. Postfix is working fine, it can send and receive mail both locally and the outside world. It puts the messages in the Maildir directories as it is supposed to. Here is my dovecot.conf file: protocols = imap imaps listen = * ssl_listen = * ssl_disable = no ssl_cert_file = /etc/pki/dovecot/certs/dovecot.pem ssl_key_file = /etc/pki/dovecot/private/dovecot.pem ssl_parameters_regenerate = 168 log_path = /var/log/dovecot info_log_path = /var/log/dovecot.info verbose_ssl = yes protocol imap { } auth_verbose = yes auth default { # Space separated list of wanted authentication mechanisms: # plain login digest-md5 cram-md5 ntlm rpa apop anonymous gssapi mechanisms = plain login userdb passwd { } passdb shadow { }

[Dovecot] IMAP/POP3 proxying and capability
by Laurent Papier 10 Aug '06

10 Aug '06

Hi, I setup a rather large POP3/IMAP configuration and want to use dovecot proxying feature. I have noted that the capability announce when connecting via the proxies are not the same before you are authenticated and after. Before you are authenticated the proxy announce is own capability and after it announce the final server capability. The problem is that some (most ? all ?) mail client ask for capability before authenticate to the server. So if the proxy capability are not the same as the final server capability the client gets wrong information. I use the QUOTA extension and it doesn't make sens to activate the quota feature on the proxy. Any other suggestion ? Perdition can hardcode the capability string the his configuration file. This is not perfect as the capability can change but it's an acceptable workaround for me. -- Laurent Papier - 03 88 75 80 50 Admin. système - SdV Plurimedia - <http://www.sdv.fr/>

Any other suggestion ? You can modify the "capability" variable around line 31096 of the "configure" file before you compile dovecot. Bill

[Dovecot] Issue building rc6 on Mac OS X (quota)
by James Berry 09 Aug '06

09 Aug '06

I haven't had time to put together a patch, but quota-fs.c fails to compile on Mac OS X. Any chance we could get a configuration switch that says "--without- quota"? I've resolved the problem temporarily by forcing HAVE_FS_QUOTA to undef in quota-fs.h. James

Re: [Dovecot] Dovecot imap with Postfix and using Thunderbird as client
by Shawn Needham 09 Aug '06

09 Aug '06

Hi, I was wondering if anyone knew of the mysterious fix to this problem that Curtis describes in his followup: "I vaguely remember something like this, but I don't recall the fix" I recently installed dovecot on a server running RHEL4-AS-U2 and have updated to RHEL latest dovecot package, dovecot-0.99.11-2.EL4.1. Seeing as this is close to the version Curtis is running (dovecot-0.99.14) I was wondering if anyone had some insights. There seems to be a Thunderbird specific problem when trying to retrieve messages from the server. Other imap clients (Mac OSX Mail, squirrelmail, etc) don't experience this problem, however Thunderbird 1.5.0.5 experiences it on Linux, Mac OSX and Windows boxes. In thunderbird, new messages don't reliably appear and the retrieval button doesn't work when new mail is present. Clicking on an email which isn't cached retrieves new ones as well as waiting around an hour to retrieve messages. Thanks in advance for any insight you can provide.

[Dovecot] Can't move messages
by Paul van Erk 09 Aug '06

09 Aug '06

Hi, I use dovecot with IMAP over SSL and with Plain Text authentication. I've been using that for quite a while, but now (with my new PC), it's not working like it should (I tried several 1.0* releases, including 1.0-rc6. The problem is that I can't move messages from one IMAP folder to another, no matter which mail client. When I use KMail, I get: "The connection to the server parena was unexpectedly closed or timed out. It will be re-established automatically if possible." But everything still works. The messages hasn't moved (deleting (so send to Trash folder) also doesn't work), it stays where it is. With Thunderbird, it just goes nuts in the status bar saying "Connecting..." and some other messages: clearly it tries to move, loses the connection and tries again and again... An extra weird thing is when I move a message from my IMAP account to a local folder, it works. And then I can move that message from the local folder to my IMAP account. It only doesn't work when moving messages within the IMAP account. I use: openssh 4.3_p2-r1 openssl 0.9.7j I hope someone can help me, 'coz my wife will soon start to find it just as annoying as I already do. ;) Paul van Erk

[Dovecot] rc6 compilation problems (obsd 3.9 stable)
by Michal Soltys 09 Aug '06

09 Aug '06

Starting with rc6, there seem to be problem with compilation on openbsd 3.9, (possibly due to autoconf 2.60 switch mentioned in other thread ?). Either way, this is what configure reports at some point (further compilation fails of course): checking for crypt... yes checking for dlopen... yes checking whether byte ordering is bigendian... no ./configure: echo $(top_builddir)/src/lib-storage/index/maildir/libstorage_maildir.a: not found ./configure: echo $(top_builddir)/src/lib-storage/index/mbox/libstorage_mbox.a: not found ./configure: echo $(top_builddir)/src/lib-storage/index/dbox/libstorage_dbox.a: not found checking zlib.h usability... yes checking zlib.h presence... yes checking for zlib.h... yes

[Dovecot] Dynamic server address
by Kresimir Tonkovic 08 Aug '06

08 Aug '06

Hi! My mail server (ubuntu breezey badger) is connected by ADSL and has a dynamic address. I have noticed that, every day after the IP address changes, dovecot is no longer reachable from the net. Iguess this is because dovecot doesn't register this change and continues to listen on a non-existing interface/address. I'm trying to solve this problem by putting a script in /etc/ppp/ip-up/ dovecot --===--- #!/bin/sh # By kresho # dovecot ip-up script (/etc/ppp/ip-up.d/dovecot) # /etc/init.d/dovecot restart ---===--- So far, it seems to work. I doubt I'm the first one to come across this problem, yet I couldn't find anything similar on google. Any comments? -- kresho

Hi all, Firstly if this is a FAQ and I've missed it - let me apologise in advance. I use dovecot as a backup mail store and would now like to purge all mails over a certain age. Is it as simple as using find and rm'ing the results or is there more to it? I'm using maildir if that make a difference? Thanks in advance. Daveh

[Dovecot] RC6 startup failure: "Login prcess died too early"
by S JList 07 Aug '06

07 Aug '06

Greetings. I have been running Dovecot-1.0rc2 on a test server for the last couple of weeks. No problems. However, when I installed RC6 this morning, Dovecot refused to launch completely. Here's the relevant snippet from /var/log/maillog: Aug 7 10:08:36 mercury dovecot: Dovecot v1.0.rc6 starting up Aug 7 10:08:37 mercury dovecot: Login process died too early - shutting down Aug 7 10:08:37 mercury dovecot: child 26127 (login) killed with signal 11 Aug 7 10:08:37 mercury dovecot: child 26128 (login) killed with signal 11 Both RC2 and RC6 compiled cleanly with "--with-pop3d". For reasons beyond my control, I have to set protocols = imap pop3 disable_plaintext_auth = no ssl_disable = yes I do have a valid /etc/pam.d/dovecot file (we're using PAM). I made certain that the localized settings for /usr/local/etc/dovecot.conf matched what they were in RC2 for RC6. (I did use the RC6 dovecot-example.conf as source for RC6, then made the local changes. I also tried testing RC6 with my old RC2 config file--same failure). So, RC2 starts just fine. RC6 fails to start with the messages logged above. Can anyone give me any pointers? RHEL (Linux Kernel 2.6.9-34.0.2.ELsmp), built from source, nothing out-of-the-ordinary. Right now, I've reverted back to RC2. TIA. S JList sjlist(a)heidelberg.edu

[Dovecot] Stale imap processes
by Martin Jackson 07 Aug '06

07 Aug '06

Hello, I'm new to the list, but I noticed a buildup of stale imap processes after upgrading to 1.0rc2. My IMAP server actually ran over maxpipekva, and I had to reboot it. I got to spend some time learning about kern.ipc.maxpipekva in the process of troubleshooting. I'm running FreeBSD 6.1-RELEASE-p3, and I have a small home office LAN setup. 2 XP client PC's, one which uses primarily Thunderbird 1.5.0.5, one which uses primarily Outlook Express. I had been running with SSL under Thunderbird (only), but disabled that in hopes of fixing the problem. It appears not to have helped. I am using the FreeBSD dovecot port, currently at rc2, with default settings. I use the default authentication scheme, and Maildir storage (my MTA is Postfix). I am running a number of other daemons on this machine but mail is its main function. I am interested in helping to solve this problem; is there anything I can do to help? Thanks, Marty

[Dovecot] 1.0 RC6 released
by Timo Sirainen 07 Aug '06

07 Aug '06

http://dovecot.org/releases/dovecot-1.0.rc6.tar.gz http://dovecot.org/releases/dovecot-1.0.rc6.tar.gz.sig Back to rc1's SSL proxying code with some improvements, which hopefully now makes everyone happy. I'm seeing all kinds of problems with namespace prefixes and LIST code. I guess it would be important to fix it before v1.0 since it makes upgrades from other servers easier.. I also tried looking into the "Unknown namespace" problems that happens if you try to create only one namespace with "INBOX." prefix. I couldn't really figure out what causes those errors. Could someone show me what commands the client tries to use which causes it? * Removed login_max_logging_users setting since it was somewhat weird in how it worked. Added login_max_connections to replace it with login_process_per_connection=no, and with =yes its functionality is now within login_max_processes_count. + Added --with-linux-quota configure option to specify which Linux quota version to use, in case it's not correct in sys/quota.h. Usually used as --with-linux-quota=2 + acl plugins: If .DEFAULT file exists in global ACL root directory, use it as the default ACLs for all mailboxes. - Fixes to login process handling, especially with login_process_per_connection=no. - Back to the original SSL proxy code but with one small fix, which hopefully fixes the occational hangs with it - Several fixes to handling LIST command more correctly.

[Dovecot] Dovecot proxy: Too many open files
by Bill Boebel 06 Aug '06

It appears that when running Dovecot as a proxy-only box with "login_process_per_connection = no", it ignores the value of login_max_logging_users. And in Linux, since each socket requires a file descriptor, if you don't increase the maximum number of open files that each process is allowed to have open, imap-login will reach the 1024 open file limit and start logging the following errors: imap-login: socket() failed: Too many open files imap-login: Internal login failure: user=... imap-login: socketpair() failed: Too many open files Here are the settings I am testing with: login_process_per_connection = no login_max_logging_users = 225 login_processes_count = 20 login_max_processes_count = 30 And here the output of "lsof -nu dovecot" when one of the imap-login processes reaches its open file limit. In this case PID 20087 had 362 users connected, but it should have allowed no more than 225 users, which would have kept it from reaching the open file limit: (sent directly to Timo since it was too big to post to the list) Also, I am running CVS dovecot-20060725.

[Dovecot] Using mail_chroot and default_mail_env
by Daniel Kauffman 06 Aug '06

06 Aug '06

Settings for mail_chroot and default_mail_env are not playing well together. It seems that default_mail_env is verified to exist *before* the chroot but is later used *after* the chroot. A configuration like this: * mail_chroot = /var/mail/example.com/username * default_mail_env = maildir:/Maildir Fails with the message: * stat(/Maildir) failed: No such file or directory As a work-around, I created an empty directory named Maildir *outside* of the chroot. The relevant portions of the filesystem now look something like this: * /Maildir * /var/mail/example.com/username/Maildir/... NOTE: The empty /Maildir directory is owned by root. NOTE: Each /var/mail/example.com/username directory and up is owned by root. NOTE: Each /var/mail/example.com/username/Maildir directory and below is owned by the email user. After successful testing with the "static" settings above, I was able to pull the per-user settings for mail_chroot in from PostgreSQL using home to over-ride mail_chroot. If anyone else has been having trouble with mail_chroot + default_mail_env, hopefully this work-around will help. Finally, I should mention my system, just in case I am the only one affected... * Xen + Linux 2.6.16.13 + Debian 3.1 + ( Dovecot 1.0rc2 in chroot ) Regards, Daniel Kauffman

[Dovecot] ldap + dovecot
by Gert Horne 06 Aug '06

06 Aug '06

Hi again, I am still struggling with ldap and dovecot. I have my dovecot authenticating against ldap. The problem now seems to be of a permission type. I am also trying to figure out the default_mail_env and valid_chroot_dirs settings. may maillog gives me: IMAP(user): Ambiguous mail location setting, don't know what to do with it: /var/spool/mail/ (try prefixing it with mbox: or maildir:) server dovecot: IMAP(user): Failed to create storage with data: /var/spool/mail/ Can anyone help me please.

[Dovecot] daemontools
by Rick Romero 05 Aug '06

05 Aug '06

Hi, I just started running RC2 on Thursday. I migrated an old Courier IMAP server, and the only issue I had was that I didn't understand how to enable quotas :) It's impressively fast, and I'm quite happy with it so far. This morning I found that dovecot had crashed, I had exceeded FreeBSD's kern.maxpipekva Has anyone successfully run dovecot under daemontools? I got it to fire up, but it didn't seem to work right.. I'm guessing it's a rights issue, but I haven't delved into it at all. Thanks! Rick

[Dovecot] Dovecot proxy in front of UWash?
by Vincent Fox 05 Aug '06

05 Aug '06

Is it possible to use Dovecot frontends in front of UWash backends? I need a proxy pool ASAP. There is not sufficient time to migrate the backends for 40,000+ users so they have to stay UW for now. I have been looking at Perdition but concerned about performance under load. Dovecot looks really promising with it's non-forking mode. I need simple dumb frontends no local mail. Other questions: 1) Database? Wiki only talks about SQL, can I have it map username to hostname using LDAP or some other mechanism? 2) Kerberos? I am hazy here, but can I have the frontends auth the user via Kerberbos and things "just work"? Or do I need to stick with PLAIN authentication? 3) Port mappings? Can I have the requests coming in on SSL ports remapped to non-SSL ports on the backends? Thus the backends could have their load reduced somewhat. e.g. client->proxy:993->backend:143

In postgresql you can do something like select 'maildir:' || maildir as mail, uid, ... through dovecot-sql.conf Is there a mysql equivalent for adding 'maildir:' as a prefix to the 'mail' location ?

[Dovecot] Thunderbird and hanging "Copying message to Sent folder..."
by M.-A. Lemburg 04 Aug '06

04 Aug '06

Here's a work-around for the problem that appears to work and maybe also hints at the root of the problem: If you setup the Thunderbird account to "Place a copy in:..." "Other" and then select the Sent folder of the account (rather than just selecting "Sent Folder on: ..."), the problem appears to go away. I can't tell for sure, but Thunderbird seems to send the copy using a different connection than the one used for sending the message itself if you set things up in this way. The email still gets copied to the same Sent folder, so there's no change there. -- Marc-Andre Lemburg eGenix.com Professional Python Services directly from the Source (#1, Aug 03 2006) >>> Python/Zope Consulting and Support ... http://www.egenix.com/ >>> mxODBC.Zope.Database.Adapter ... http://zope.egenix.com/ >>> mxODBC, mxDateTime, mxTextTools ... http://python.egenix.com/ ________________________________________________________________________ ::: Try mxODBC.Zope.DA for Windows,Linux,Solaris,FreeBSD for free ! ::::

[Dovecot] Stale imap processes
by Fran Fabrizio 04 Aug '06

04 Aug '06

Anyone have any theories or experiences as to why for a certain user, some of his imap processes hang, and stay around for days and days? He just reported that his Thunderbird was timing out when trying to open folders, I looked on the server, and he had 3 old imap processes from 1 week+ ago. I killed those and his performance immediately improved. He checks mail with Thunderbird > 1.5 from both Win and Linux, Squirrelmail webmail, and pine. Of those, pine is the only one that is somewhat rare around here - any specific problems with pine's imap client code that anyone knows about? We have been using the dovecot-1.0-0.beta2.7 rpm for Fedora Core 5, I'm updating to 1.0-0.beta8.2.fc5 to see if that helps, as well. Just curious if anyone else has seen this lately.

[Dovecot] RC5 Outlook POP3 problem
by DNSExit Com 04 Aug '06

04 Aug '06

We have been using dovecot v1.0 alpha3 for almost 1 year for our mail hosting. It was running great until more accounts added to the hosting. I have been trying to upgrade it to v1.0 rc5 and we have found that the RC5 has problem with Outlook (Express) with POP accounts. We are getting error with POP3 on Outlook Express: Your server has unexpectedly terminated the connection. Possible causes for this include server problems, network problems, or a long period of inactivity. Account: 'box5.dnsexit.com', Server: 'box5.dnsexit.com', Protocol: POP3, Port: 110, Secure(SSL): No, Error Number: 0x800CCC0F Do you know if this is a bug or it is our configuration problem? I tried it on Thunderbird and it works great. Both Outlook and Outlook express fail. Are there anyone getting the same problem?

[Dovecot] Dovecot IMAP and Mac OS X Mail.app
by Ronny Adsetts 04 Aug '06

04 Aug '06

Hi All, I recently switched our Courier IMAP server over to Dovecot primarily for performance reasons. Server OS is Debian Sarge with Dovecot packages from backports.org (v 1.0.rc2-1bpo1). Access from Thunderbird and Horde worked fine with some shared folders defined and the Courier compatibility private folder stanza. Initial testing with Mail.app showed that, although the folder listing was fetched correctly including all shared folders, no mail could be viewed with Mail.app timing out with an error about invalid namespace. (I'll post the exact error message as a follow up when I can test again later). After searching the mailing list for a while, I came upon a message suggesting adding a second private namespace like so: namespace private { separator = . prefix = "INBOX." inbox = yes hidden = no } namespace private { separator = . prefix = inbox = yes hidden = yes } Now, this does work in a fashion and allows Mail.app to access the folders and mail. Problem with this config: * Mail.app displays all INBOX. folders at the top level *and* below Inbox * Thunderbird displays a spurious INBOX folder in the folder listing under Inbox. * Horde displays folders at the top level and below Inbox. Whilst not being a huge problem for our internal mail server, this is not optimal. Has anyone else had these or similar problems and managed to work them out? If so, how did you configure Dovecot or the clients to all play nicely together? I'd quite like to roll Dovecot out on our client mail server but I need to work this out first so any help is appreciated. Thanks.

[Dovecot] Can't change permissions for /var/spool/postfix/dovecot.index.log
by James Brown 04 Aug '06

04 Aug '06

For some reason i can't change the permissions on /var/spool/postfix/ dovecot.index.log from postfix to dovecot, or anything else. I changed all the files in /var/spool/postfix to be owner postfix so that postfix wouldn't complain about insufficient priviledges. I'm running MacOS X 10.4.7. I can change it all I want, but the owner and group changes do not 'stick' - they simply stay at postfix. Does anyone have any ideas? Can I have the index and index.log files elsewhere? Thanks, James.

[Dovecot] alternate rawlog directory
by Thomas Hummel 03 Aug '06

03 Aug '06

Hello, In rc2 sources, the rawlog directory seem to be hard-coded to be looked for in $HOME. I'd like to have a way to centralized the place where rawlog files are, in order to be able : . to rotate them more easily . not to leave them at the user's reach . not to have to enter the user's directory to read them I'd like to have a layout similar to this : /var/log/dovecot.rawlog/ /user1/20060708-093811-45581.in /user1/20060708-093811-45581.ou /user1/... /user2/20060708-093811-45590.in /user2/20060708-093811-45590.out What do you think about that idea ? Is there already a patch to do that, should I change rawlog.c or is ther already a regular way do do that ?

I should have looked closer at the log entries. I went to my maildir and ran a find . -name "dovecot.index*" -print0 | xargs -0 rm -f, which got rid of all the index files, but left the uidlists alone. That worked. The 64 bit dovecot is now running fine. So I guess we know that a 32 bit and a 64 bit dovecot can't both use the same mail store. Doesn't the dovecot front page talk about sanity checks being done to prevent this kind of stuff? This makes dovecot seem brittle. Anyway, thanks for the help. cheers, Scott

If I remove the index files and let dovecot rebuild them, won't that lead > to my users re-downloading their entire inboxes if they're using POP3? Depends on how you have the UIDL format configured. Personally I use maildirs and have the format be the filenames so I can continue to use qmail-pop3d (for now). If you're using the default, yeah, I think that's a generated id. Another option would be to recompile dovecot on the 64bit system with the --with-file-offset-size=32 instead of the RPMs. It is really an easy build. Personally, first I'd try removing the index files for my own account and see if my mail gets re-downloaded. Please note that I've done very little on 64bit systems, so these are mostly guesses. But I have compiled with --with-file-offset-size=64 and had to remove my index files to avoid that crash. > -Scott >

Hey everyone, I'm trying version 1.0rc2, via the rpm at ATrpms. I'm running on CentOS 4.3 on an Opteron system. I have this running stably on a 32 bit system, but I'm crashing constantly on a 64 bit system. Here's what I'm getting in my mail logs when I try to log in via IMAP: Aug 3 15:01:21 lisa dovecot: imap-login: Login: user=<scottz>, method=PLAIN, rip=::ffff:192.168.1.183, lip=::ffff:192.168.1.21 Aug 3 15:01:22 lisa dovecot: IMAP(scottz): file index-mail.c: line 105 (index_mail_get_fixed_field): assertion failed: (buffer_get_used_size(buf) == data_size) Aug 3 15:01:22 lisa dovecot: imap-login: Login: user=<scottz>, method=PLAIN, rip=::ffff:192.168.1.183, lip=::ffff:192.168.1.21 Aug 3 15:01:22 lisa dovecot: child 3208 (imap) killed with signal 6 Aug 3 15:01:22 lisa dovecot: IMAP(scottz): file index-mail.c: line 105 (index_mail_get_fixed_field): assertion failed: (buffer_get_used_size(buf) == data_size) Aug 3 15:01:22 lisa dovecot: imap-login: Login: user=<scottz>, method=PLAIN, rip=::ffff:192.168.1.183, lip=::ffff:192.168.1.21 Aug 3 15:01:22 lisa dovecot: child 3210 (imap) killed with signal 6 Aug 3 15:01:22 lisa dovecot: IMAP(scottz): file index-mail.c: line 105 (index_mail_get_fixed_field): assertion failed: (buffer_get_used_size(buf) == data_size) Aug 3 15:01:22 lisa dovecot: imap-login: Login: user=<scottz>, method=PLAIN, rip=::ffff:192.168.1.183, lip=::ffff:192.168.1.21 Aug 3 15:01:22 lisa dovecot: child 3212 (imap) killed with signal 6 Aug 3 15:01:22 lisa dovecot: IMAP(scottz): file mail-cache-transaction.c: line 709 (mail_cache_add): assertion failed: (fixed_size == (unsigned int)-1 || fixed_size == data_size) Aug 3 15:01:22 lisa dovecot: imap-login: Login: user=<scottz>, method=PLAIN, rip=::ffff:192.168.1.183, lip=::ffff:192.168.1.21 Aug 3 15:01:22 lisa dovecot: IMAP(scottz): file mail-cache-transaction.c: line 709 (mail_cache_add): assertion failed: (fixed_size == (unsigned int)-1 || fixed_size == data_size) Aug 3 15:01:22 lisa dovecot: imap-login: Login: user=<scottz>, method=PLAIN, rip=::ffff:192.168.1.183, lip=::ffff:192.168.1.21 Aug 3 15:01:22 lisa dovecot: child 3214 (imap) killed with signal 6 Aug 3 15:01:22 lisa dovecot: child 3218 (imap) killed with signal 6 Can someone confirm whether this is a bug or not? thanks, Scott

[Dovecot] 1.0 RC3 released
by Timo Sirainen 03 Aug '06

03 Aug '06

http://dovecot.org/releases/dovecot-1.0.rc3.tar.gz http://dovecot.org/releases/dovecot-1.0.rc3.tar.gz.sig Does this fix the hangs people have been reporting? - SSL connections hanged sometimes, especially when saving messages. - mbox: Mail bodies were saved with CR+LF linefeeds - Mail forwarding was broken with deliver/Sieve - dbox fixes. Might actually be usable now. - Index file handling fixes with keywords - Cache file was incorrectly used in some situations, which probably caused problems sometimes. - Maildir++ quota: Don't count "." and ".." directory sizes to quota. After rewriting maildirsize file keep its fd open so that we can later update it. Patch by Alexander Zagrebin
