[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 ?

[Dovecot] Pb with ssl_disable in 1.0RC6
by Laurent Papier 11 Aug '06

11 Aug '06

Hi, I have a problem after upgrading dovecot 1.0rc1 to 1.0rc6. I don't use SSL at all so I have 'ssl_disable = yes' in my configuration. This works fine in 1.0rc1 but dovecot 1.0rc6 failed to start with the following error message "dovecot: Login process died too early - shutting down". Setting 'ssl_disable = no' resolves the problem but now dovecot announce TLS capability which is not what I want. Any suggestion ? -- Laurent Papier - 03 88 75 80 50 Admin. système - SdV Plurimedia - <http://www.sdv.fr/>

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

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
by polish 11 Aug '06

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

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.

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! I'll get to it eventually, and you can reuse most of the code from the plugin!) See http://members.plug.org.au/~linuxalien/dokuwiki/projects:dovecot-mysql-dspa… for more details, and the code! Feed back, comments, and criticism are all welcome! Tim -- Linux Counter user #273956

[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

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?
by James Berry 10 Aug '06

10 Aug '06

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 { }

I tried to google about this problem but what I found were related to other processes such as imap etc. Thanks in advance for your help. -- Ceasar

[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/>

[Dovecot] SSL hangs? Try this
by Timo Sirainen 09 Aug '06

09 Aug '06

Since apparently 1.0 RC5 didn't fix the SSL hangs for everyone, could you try if replacing src/login-common/ssl-proxy-openssl.c with this helps: http://dovecot.org/tmp/ssl-proxy-openssl.c It's basically the old proxying but with some new changes, plus hopefully also fixing the original rarely occurring hang which my rewrite was intended to fix.

[Dovecot] When auth_process_size is reached
by Bill Boebel 09 Aug '06

What does Dovecot do when dovecot-auth reaches the max size defined by auth_process_size? Does it just prevent it from growing further, or does it cause any problems? Thanks, Bill

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
