[Dovecot] Sent / Drafts / Trash folders and subscribing ?
by Xavier Beaudouin 17 Sep '07

17 Sep '07

Hello, I am trying to migrate our configuration that use Courier-imap to dovecot, appart some users that have some issues with pop and leave messages on servers that retreive all mails into their mailboes... but this is ok for me :).. One problem that it seems that Sent / Drafts and Trash folder are not automaticaly added as subscribed folder... I really dunno about IMAP rfc or standard, I just want to know if this is considered as normal for dovecot ? Thanks, /Xavier -- Xavier Beaudouin - http://oav.net/

[Dovecot] v1.1.alpha6 released
by Timo Sirainen 17 Sep '07

17 Sep '07

http://dovecot.org/releases/1.1/alpha/dovecot-1.1.alpha6.tar.gz http://dovecot.org/releases/1.1/alpha/dovecot-1.1.alpha6.tar.gz.sig Most importantly doesn't crash anymore if both pop3 and imap aren't used. :) I'm hoping people won't find anything too bad from this release anymore, so I'll release v1.1.beta1 in a week or so. I also finally did some larger API changes and code cleanups that I had been planning on doing for a long time. I also changed copyright notices in the code to: /* Copyright (c) xxxx-2007 Dovecot authors, see the included COPYING file */ So my name isn't there anymore. It wasn't always correct anyway. I'm planning on updating the -2007 year at the beginning of each year to all the files. It's annoying to try to keep it updated manually.

[Dovecot] Possible bug in authentication cache in dovecot 1.1.alpha4
by arvids 17 Sep '07

17 Sep '07

Hello, it seems that there is some bug in authentication cache code in dovecot version 1.1.alpha4 - after login attempt with wrong password the correct password also will fail. I can reproduce it very easy: $telnet 10.10.10.30 110 +OK Server. <861.2.46e6c679.jZ8QYpFmU8ZN6XIq7zPhkw==@server2> user testuser +OK pass pass +OK Logged in. quit +OK Logging out.

[Dovecot] Dovecot stops talking to the auth server.
by Tom Diehl 17 Sep '07

17 Sep '07

Hi, I have an RHEL4 machine running dovecot-1.0.3 + postfix-2.3.2 + postfixadmin + mysql-4.1.20-2.RHEL4.1 + amavisd-new-2.5.2-1. The machine only has a gig of memory in it, I am trying to keep it running until I get new hardware to replace it in a couple of weeks. For the most part it works as advertised but every once in a while it stops talking to the auth server. I think I have tracked this to periods of high auth requests. Today the machine experienced a dictionary attack and I had log entries like the following: Sep 10 13:31:06 rocky dovecot: pop3-login: Disconnected: Shutting down: rip=::ffff:24.0.201.240, lip=::ffff:192.168.0.16 Sep 10 13:31:06 rocky dovecot: pop3-login: Can't connect to auth server at default: Resource temporarily unavailable Sep 10 13:31:07 rocky last message repeated 47 times Sep 10 13:31:08 rocky dovecot: pop3-login: Disconnected: Shutting down: rip=::ffff:24.0.201.240, lip=::ffff:192.168.0.16 Sep 10 13:31:08 rocky dovecot: imap-login: Can't connect to auth server at default: Resource temporarily unavailable Sep 10 13:31:08 rocky dovecot: pop3-login: Can't connect to auth server at default: Resource temporarily unavailable Sep 10 13:31:09 rocky last message repeated 27 times Sep 10 13:31:09 rocky dovecot: imap-login: Can't connect to auth server at default: Resource temporarily unavailable Sep 10 13:31:09 rocky dovecot: pop3-login: Can't connect to auth server at default: Resource temporarily unavailable Sep 10 13:31:09 rocky last message repeated 4 times Sep 10 13:31:09 rocky dovecot: imap-login: Can't connect to auth server at default: Resource temporarily unavailable ... a ps showed numerous defunct processes similar to the following: ... nobody 16647 0.0 0.2 9784 2112 ?

[Dovecot] Dovecot Sieve crash
by Julian Cowley 16 Sep '07

16 Sep '07

I just transferred the files in my home directory from an x86_64 machine to an i686 machine. This included the .dovecot.sieve and .dovecot.sievec files in my home root, and the Dovecot index files in my ~/Maildir directory. Everything seemed to be working until I tried sending an email that triggers a Sieve "redirect" command, then I got the following in the logs. I then tried the same dovecot.sieve file using a separate account which has always been on the i686 machine (and the index files have always been written there too), and the Sieve "redirect" worked fine. There were core files written in my home directory which I can post if necessary. Both the x86_64 and i686 machines are CentOS 4.5 running Dovecot 1.0.5 and Dovecot Sieve plugin 1.0.1.

[Dovecot] Dovecot Periodically Stops Authenticating Users
by David Gitman 16 Sep '07

16 Sep '07

Hi, It seems that my dovecot installation periodically stops authenticating users. Restarting dovecot resolves the issue temporarily. I'm authenticating via PAM to OpenLDAP on a CentOS 4 box. I've seen several related posts about this issue but no resolution. My logs show: Sep 15 03:58:24 server01 dovecot: imap-login: Can't connect to auth server at default: Resource temporarily unavailable Sep 15 03:58:24 server01 dovecot: imap-login: Can't connect to auth server at default: Resource temporarily unavailable And my configuration is: /usr/sbin/dovecot --version 1.0.3 /usr/sbin/dovecot -n # 1.0.3: /etc/dovecot.conf 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 mail_location: maildir:~/mail 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: pam userdb: driver: passwd Any ideas on how to resolve this?

[Dovecot] Migration woes from tpop mbox to dovecot maildir
by Chris Richardson 16 Sep '07

16 Sep '07

I was hoping some one might be able to offer me some advice on a little problem I have. I am looking to A. move from mbox to maildir B. looking to move from tpop to dovecot to bring both pop and imap under the same program. anyways the problem I am having is this tpop3d mbox uses MD5 sum of the mailbox headers in hex which is option %m in the uidl section but the problem is when dovecot convert plugin runs and makes in a maildir it fails to find the md5 of this because it is only used for mboxs. if I change this from %m to %Mf it downloads every message on the clients computer which is not desirable. I was thinking only options i have is to allow it to download all them mail and or write a script to convert it to maildir or another pop servers uidl. but i dont know much about how other pop servers generate there headers. so I was hoping maybe some one has done something similar to this or could offer some input. thanks -Chris The information transmitted is intended only for the person or entity to which it is addressed and may contain confidential and/or privileged material.

Hi, sorry for this question, but I didn't find the information in the documentation or wiki: Is mailbox_idle_check_interval (in dovecot.conf) in seconds or minutes? I think it's minutes. But ... It would be nice, if this will be in the docu of the dovecot.conf. Thanks Rupert

[Dovecot] v1.1.alpha5 released
by Timo Sirainen 15 Sep '07

15 Sep '07

http://dovecot.org/releases/1.1/alpha/dovecot-1.1.alpha5.tar.gz http://dovecot.org/releases/1.1/alpha/dovecot-1.1.alpha5.tar.gz.sig I think we're finally close to v1.1.betas. - Fixed "messages_count too large" index errors. - deliver was crashing. - Saving messages with maildir accessed freed memory, which might have caused crashes. - Index files are now never marked as "corrupted". Instead fsck is run which preserves as much of the original index as possible. This is important with dbox at least since index files are the only place where the latest flag/keyword changes are. Recent alphas were also modifying process's fd limits. The current behavior is: - If current fd limit is less than login_max_processes_count (imap +pop3) + max_mail_processes, log a warning at startup: "fd limit 1024 is lower than what Dovecot can use under full load (more than 1234). Either grow the limit or change login_max_processes_count and max_mail_processes settings" - Since 1024 is a common default limit, I dropped max_mail_processes default to 512. - Login processes drop their fd limit to the maximum number of fds needed, plus a few more just in case.

[Dovecot] Proxy problems with 1.0.5 !
by Ed W 15 Sep '07

15 Sep '07

Hi I am trying to do a staged migration over to dovecot, but having troubles at the first hurdle. I setup the proxy feature to redirect most of our users back to the current Courier imap/pop server, and it's partly working, but I'm getting some serious errors using Thunderbird and IMAP. Now, I had expected the proxying to be fairly transparent and basically just dovecot doing an auth and then passing the stream on to the other server? My problem is that using Thunderbird I can read all my folders OK, but I can't save anything in my Sent Items or Drafts folders... Basically I get errors every time I try and send an email, or try to save to the draft folder. Curiously, directly browsing into those folders works fine, as does deleting emails, and apparently copying them works fine also... Why is the saving of sent messages failing...? The setup is basically taking a working Thunderbird install, changing the server name from pointing at the Courier server to point at the dovecot server - dovecot in turn is told to proxy back to the original server. All I'm getting from Thunderbird is an "Invalid Command" response. Is there an easy way to get a look inside the imap stream to try and see what's failing? Any suggestions on why this is happening at all? One idea is that I have setup completely different namespaces in Dovecot, (with a hidden namespace which should be courier compatible), but I wouldn't have expected this to affect the Proxy stuff at all?! Grateful for any pointers to debug this - it's a fairly major hurdle for my rollout Thanks Ed W

[Dovecot] auth_default_realm for different listeners
by John Morrissey 15 Sep '07

15 Sep '07

We provide POP3 service for several realms, each of which has a substantial number of users logging in with no realm (bare username). We would like to use Dovecot, but I haven't been able to findout how to vary auth_default_realm for each listener. My most recent attempt was to set up one auth {} block for each realm with a different auth_default_realm and socket master path. I then set up one protocol pop3 {} block for each realm, listening on different IP addresses and with a auth_socket_path corresponding to the auth block for that listener. I'm not sure if I'm on the right track here, but I'm seeing two problems: 1. When dovecot starts, I get: Sep 5 18:32:21 pop01 dovecot: auth(otherdomain): Socket already exists: /var/run/dovecot/auth-otherdomain for each additional auth {} block. 2. dovecot won't start with auth_socket_path specified in a protocl pop3 {} block: Error in configuration file /etc/dovecot/dovecot.conf line 654: Unknown setting: socket_path Is there a way to vary auth_default_realm for each listener, so I can have multiple realms log in with bare usernames? thanks, john -- John Morrissey _o /\ ---- __o jwm(a)horde.net _-< \_ / \ ---- < \, www.horde.net/ __(_)/_(_)________/ \_______(_) /_(_)__

[Dovecot] namespace prefix issue with avelsieve
by it-dovecot＠ml.epigenomics.com 15 Sep '07

15 Sep '07

Hi! I am currently testing a setup with dovecot's lda, the cmusieve plugin, pysieved and the avelsieve plugin for squirrelmail. The issue I am stumbling upon is that avelsieve is generating folder names including the namespace prefix when creating "fileinto" rules. E.g.: A rule: If the header "Precedence" contains "bulk", then file it into the folder INBOX.bulk. Also keep a copy in INBOX, marked as deleted. translates into sieve: require ["fileinto","reject","vacation","imapflags","relational","comparator-i;ascii-numeric","regex","notify"]; if header :contains "Precedence" "bulk" { fileinto "INBOX.bulk"; addflag "\\Deleted"; keep; } But what happens when a matching email is delivered is that a new mailbox ".INBOX.bulk" in the user's Maildir is created. I.e. the email is not delivered to ~/.Maildir/.bulk as intended, but into ~/.Maildir/.INBOX.bulk, creating the new folder on the fly. The same happens when trying to fileinto folders from other namespaces. It seems that either avelsieve is generating "too much" and should remove the prefix (at least for INBOX) or dovecot's deliver is not able to use the namespaces definition in dovecot.conf correctly when interpreting sieve's fileinto directive. Did I miss something? This is the dovecot.conf in use: # /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S listen: *:143 ssl_listen: *:993 ssl_cert_file: /etc/courier/imapd.pem ssl_key_file: /etc/courier/imapd.pem disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login login_processes_count: 12 login_max_processes_count: 512 verbose_proctitle: yes mail_location: maildir:~/.Maildir:INDEX=/var/cache/dovecot/INBOX.%u:CONTROL=/var/cache/dovecot/INBOX.%u mail_full_filesystem_access: yes maildir_stat_dirs: yes maildir_copy_with_hardlinks: yes namespace: type: private separator: . prefix: INBOX. inbox: yes namespace: type: public separator: . prefix: shared. location: maildir:~/.Maildir/shared:INDEX=/var/cache/dovecot/shared.%u:CONTROL=/var/cache/dovecot/shared.%u namespace: type: private separator: . prefix: archive. location: maildir:/mnt/nfs/imap_archive.hm/%u:INDEX=/var/cache/dovecot/archive.%u:CONTROL=/var/cache/dovecot/archive.%u auth default: verbose: yes passdb: driver: passwd userdb: driver: passwd socket: type: listen client: path: /var/run/dovecot/auth-client mode: 432 master: path: /var/run/dovecot/auth-master mode: 384 Greetings -- Robert Sander Senior Manager Information Systems Epigenomics AG Kleine Praesidentenstr. 1 10178 Berlin, Germany phone:+49-30-24345-0 fax:+49-30-24345-555 http://www.epigenomics.com robert.sander(a)epigenomics.com

Re: [Dovecot] Dovecot / OS X 10.4 Mail.app and "Too Many Opened files" error message ?
by Xavier Beaudouin 14 Sep '07

14 Sep '07

(replying to myself) > After a long time, the OS X client say error : "Too Many opened > files". Seems that OS X has stupidly low number of files that can be opened... $ ulimit -a [...] open files (-n) 256 On my MacBook Pro.... This is bloody low.... So I've figured to change this limit globaly, but it seems that OS X don't have any limits.conf or default values.... This kinda strange.. So I decided to do some local fixe for Mail.app only : in /Applications/Mail.app/Contents/MacOS/ $ sudo mv Mail Mail.orig and ... Create a Mail file with this following content : #!/bin/sh # thanks to http://www.amug.org/~glguerin/howto/More-open-files.html # To understand this, read 'man sh' below "substring processing". # This can also be accomplished with the 'dirname' command, # but it may not be installed. here="${0%/*}" # This should be the name of your native Java-app's executable. cmd='Mail.orig' # Set all desired soft-limits here. See 'ulimit' in 'man sh'. ulimit -S -n 1000 # Execute the Java-app in the current process. See 'exec' in 'man sh'. exec "$here/$cmd" "$@" $ sudo chmod +x Mail and this all... FYI Mail.app is really strange thing.... $ lsof | grep Mail.orig | wc -l 150 Mostly all libraries and TCP connection to mail server... Maybe this can be added to Wiki even if it is not too mutch dovecot related, but can be usefull for people like me that does have lots of mail.... /Xavier

[Dovecot] gssapi, kerberos and webmail
by Denis Cardon 14 Sep '07

14 Sep '07

Hi every one, first thanks for the great job, I switched successfully from courier imap a few months ago and both the migration and maintenance went smoothly from then on. The reason I switched was gssapi support (and the easier debug) and now I have thunderbird on Linux connecting in an SSO fashion through kerberos/GSSAPI (works great). Users should be able to access their mail throught a webmail too (eg. eGroupware). I have already checked for kerberos authentication on Apache, however there seems to be no way to have ticket forwarding throught PHP. AFIAK there is thus no way to use kerberos for php-imap --> dovecot authentication. The only information available seems to be the username. So here is my question : how do people on this mailing list handle kerberos authentication with webmail? Do you use other kind of authentication on privileged port (ie with access only from apache) and just do a login/nopassword authentication (like an uid base authentication through ldapi:/// on an ldap directory for example) ? Here is what we have with thunderbird : Thunderbird -------kerberos-------> dovecot on standard port Here is what I would guess for webmail auth : Firefox ------kerberos----> Apache ----gssapi-auth-just-using-login----> dovecot on privileges port Cheers, Denis -- Denis Cardon Tranquil IT Systems 44 bvd des pas enchantés 44230 Saint Sébastien sur Loire tel : +33 (0) 2.40.97.62.67 http://www.tranquil-it-systems.fr

by Xavier Beaudouin 14 Sep '07

14 Sep '07

Hello, I am trying to move from Courier-imap to dovecot.... Even if the processes to move logical (eg name spaces etc...) went very and without any problem, I've some etrange behavior when Imap client is Mac OS X Mail.app. I've got a big mailbox that have about 3 / 4G of mail in several folder (lots !!!)... After a long time, the OS X client say error : "Too Many opened files". I have check on the servers (a FreeBSD farm of 3 servers using freebsd ports of dovecot)... And nothing special... A question : why do I have never this kind of message on courier imap and why do I get this on dovecot... ? Configuration file on demand... if needed... THanks, /Xavier

[Dovecot] pipe() error but not linked to kqueue
by Patrick Milvich 14 Sep '07

14 Sep '07

I have dovecot 1.0.5 installed on an OpenBSD 4.1 box and an OS X Server 10.4.10 box. Sure you've all heard it before, because of the pipe error, no more login processes can be launched, and I have to restart the server. dovecot: Sep 13 05:50:00 Error: pipe() failed: Too many open files I first thought this was the issue with kqueue, but I've since recompiled making sure to use poll. This also happened with 1.0.3 and 1.0.2. It also happens very specifically after a dictionary attack that lasts usually about an hour, unless I can catch it earlier. (Around 18,000 login attempts) ex: dovecot: Sep 13 05:49:58 Info: pop3-login: Aborted login: user=<aaron>, method=PLAIN, rip=62.161.41.32, lip=<local ip> dovecot: Sep 13 05:49:58 Info: pop3-login: Aborted login: user=<adm>, method=PLAIN, rip=62.161.41.32, lip=<local ip> dovecot: Sep 13 05:49:58 Info: pop3-login: Aborted login: user=<account>, method=PLAIN, rip=62.161.41.32, lip=<local ip> But after the attack has subsided for a period of time, I still have the number of file descriptors maxed out for the dovecot process. I've increased the number available to have a higher roof, but that doesn't fix the problem. Wondering if anyone else has seen this issue, and also in a generic problem. How are others dealing the the problem of being attacked in this method? Is there a max number of login tries for a given ip address within a period of time that I'm missing? :) Thanks, Patrick
