[Dovecot] dovecot 1.2: SEGV in acl plugin when selecting a shared mailbox
by Sascha Wilde 24 Oct '08

24 Oct '08

Hi Timo, there is a bug in the acl plugin (in head, _without_ our acl changes), which causes an segfault on selecting a shared folder. * OK [CAPABILITY ...] Dovecot ready. x login 1(a)example.com secret x OK [CAPABILITY ...] Logged in y select "users/2(a)example.com/INBOX/bla" - Peer has closed the GNUTLS connection The dovecot.log shows a segfault: [...] child 4507 (imap) killed with signal 11 This _only_ happens when the shared mailbox wasn't accessed in the same session by any other means like MYRIGHTS or LSUB (when subscribed). After doing one of those selecting works too... If it helps I can generate a gdb backtrace. cheers sascha -- Sascha Wilde OpenPGP key: 4BB86568 http://www.intevation.de/~wilde/ http://www.intevation.de/ Intevation GmbH, Neuer Graben 17, 49074 Osnabrück; AG Osnabrück, HR B 18998 Geschäftsführer: Frank Koormann, Bernhard Reiter, Dr. Jan-Oliver Wagner

No, the protocol (IMAP/POP3) is irrelevant. The important part to note (and where I suspect your problem is) is that the folder, as far as your client (Thunderbird) is concerned, is "Maildir/", the "Maildir/ new/" directory is part of Maildir's internal format. That is to say, you should never be putting "Maildir/(new|cur|tmp)" as a mailbox name into a client, just "Maildir/". -N.

[Dovecot] ManageSieve v0.11.0 released for Dovecot 1.2.alpha3
by Stephan Bosch 24 Oct '08

24 Oct '08

Hello Dovecot users, I have composed a release of the ManageSieve service for Dovecot v1.2. I also added two new capabilities that were added to the ManageSieve specification. Just like the last few releases, this new release supports the new Sieve plugin already. Change Log v0.11.0 ------------------- * Upgraded to Dovecot v1.2 * Added support for new ManageSieve capabilities RENAME and NOOP * Moved sieve settings to plugin {} section of config file. Now the settings `sieve` and `sieve_dir` in the plugin section are used for both the Sieve plugin and the ManageSieve service, avoiding the posibility of accidental differences in configuration. Installation ------------ The full installation procedure and other relevant information regarding ManageSieve is supposed to be available on the Dovecot wiki: http://wiki.dovecot.org/ManageSieve However, the changes regarding the config file are not properly described there yet. Refer to the package's README file in stead. New release: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.0.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.0.tar.gz.s… I have released a new patch for Dovecot v1.2 as well: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.alpha3-managesieve-0.11.0.d… http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.alpha3-managesieve-0.11.0.d… My public key (id: 3DFBB4F4) can be found at wwwkeys.pgp.net.

[Dovecot] logging IMAP username rather than UNIX username
by Dale Gallagher 23 Oct '08

23 Oct '08

Hi there I'd like to change my setup to log the _actual_ IMAP user's login, rather than the UNIX username. My system uses a virtual uid setup with qmail, where the mailboxes are owned by the 'vmail' user and authentication is via checkpassword using user%domain (ie email, just with % instead of @). So dovecot is recording _all_ logins as: imap-login: Login: user=<vmail>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured I have the following log format specified: login_log_format_elements = user=<%u> method=%m rip=%r lip=%l %c I have also tried: login_log_format_elements = user=<%n@%d> method=%m rip=%r lip=%l %c However, this results in a log file entry of: imap-login: Login: user=<vmail@>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured How do I configure dovecot to log the _actual_ username which the client supplies during authentication? Thanks Dale

[Dovecot] Dovecot returns the same UIDL for another message
by Alexander Shikoff 23 Oct '08

23 Oct '08

Hello, I have a serious problem with dovecot and mbox format. dovecot returns the same UIDL for new messages and as result some MUAs don't retrieve new mail. UIDs returned by UIDL command look like 000000*1c*49006cec And there is a moment when dovecot stops incrementing marked digits. In other words when new message arrive to mbox, UIDL command returns used UID. I'll show with example: 1. Send some message and try to retrieve UIDL via telnet: # echo test-mailbox-1 | mail -s Test-1 mbox(a)cu.kiev.ua # telnet pop3.cu.kiev.ua 10110 Trying 193.108.130.4... Connected to emx.itcons.net.ua.

Is there some simple textual frontend to the ManageSieve protocol somewhat easier to use than gnutls-cli? I.e. something to use like managesieve -u ef putscript myscript < /tmp/myscript Password: managesieve -u ef setactive myscript Password: simply doing the TLS authentication and length computation for me.

[Dovecot] dovecot 1.0 to 1.1 upgrade and filesystem separators
by Ian Thurlbeck 23 Oct '08

23 Oct '08

Dear All I have a test system where I am trying out 1.1.4 On the old 1.0rc6 (!) system I had edited: src/lib-storage/index/maildir/mail-storage.h to change: #define MAILDIR_FS_SEP ';' #define MAILDIR_FS_SEP_S ";" so I can get some mail folder hierarchy and '.'s in folder names - this all worked perfectly. Under 1.1.4 the MAILDIR_FS_SEP lines are no longer present. What is the current practice for doing what I was doing before ? Many thanks!

Can you reproduce it? I can't really see how it's crashing. Could you apply the attached patch, and also compile the lib/*.c and lib-mail/istream-header-filter.c without -O2 so the backtrace will be more usable? (I usually do it by removing -O2 from the subdirs' Makefile and then make clean + make in those subdirs.)

Thanks Jose, Yes in the advanced options on email clients there is always a place to put the root folder path or (some similar name) and on the old server I used ~/mail/ in all of the email clients (thunderbird, outlook, seamonkey etc) and that worked fine. Doing that on the new dovecot based server produces the effect I've described - a folder called mail visible at the same level as inbox and the other IMAP folders inside that. On the older imapd based server doing the same thing produced a view of inbox with no mail folder ... just the IMAP folders in it displayed at the same level as inbox.

[Dovecot] mail_location & NFS mounted home dirs
by Roger Hale 23 Oct '08

23 Oct '08

Hi, I'm fairly new to Dovecot, migrating from a POP-only system with /var/mail only mailboxes. I'm currently on version 1.0.10 on Solaris 10, but I don't think that's relevant to the question. I'm a little overwhelmed by the number of configuration options at the moment. I took the "standard" mail_location = mbox:~/mail:INBOX=/var/mail/%u setting in dovecot.conf. This mostly works fine, but home dirs are NFS mounted and in the event that an NFS server is down users cannot read their mail. This is the case even for users who only use POP. So, my question is, do folks on this list have good suggestions for optimum ways to deal with this so that users (perhaps only POP users) can read their mail independent of home directories being available? I think I can make something up, but I'd rather take a standard approach if there is one. If this has already been discussed I apologise - just point me to it as I didn't find it.

[Dovecot] dovecot-deliver occasionally fails to deliver, leaving no clues
by Lucas Madar 22 Oct '08

22 Oct '08

Hello, I have a FreeBSD 7.1 x86 system using dovecot with postfix and a mysql user database. Everything works completely fine, except that on occasion dovecot-deliver fails. When postfix tries to redeliver the message in about 15 minutes, it succeeds. So this isn't a very big problem, just an annoying puzzle. Here's the postfix log. At first, I thought it could be a postfix delivery problem. Oct 17 00:36:22 xxxxxxx postfix/pipe[16017]: 41E581CC5B: to=<xxxx(a)xxxxx.xxx >, relay=dovecot, delay=0.04, delays=0. 01/0/0/0.03, dsn=4.3.0, status=deferred (temporary failure) I turned on delivery logging to see what I'd get, and I simply get this: deliver(xxxxxx(a)xxxxx.xxx): Oct 17 00:36:22 Info: Loading modules from directory: /usr/local/lib/dovecot/lda deliver(xxxxxx(a)xxxxx.xxx): Oct 17 00:36:22 Info: Module loaded: /usr/ local/lib/dovecot/lda/lib90_cmusieve_plugin.so (normally, here it would print out more info about the user, as "auth input" lines, but it doesn't when it fails in this way) Dovecot is not dumping core, or even printing out any error message that I can see. I have all logging turned on (except for passwords), and I still seem to get nothing. I've attached my dovecot -n output, which doesn't seem to contain the logging I have set up for deliver: log_path = /var/log/delivery.log info_log_path = /var/log/delivery.log mail_debug = yes auth_debug = yes auth_verbose = yes Any clue as to what could be going on here? Thanks, Lucas

[Dovecot] dovecot and postfix with tls and dovecot sasl issues for smtp clients

This issue is peripherally related to the following thread Re: [Dovecot] client certs with godaddy ssl cert This is running on CentOS 5.2 with latest Atrpms for Dovecot as of this weekend. # rpm -qa | grep dovecot dovecot-sieve-1.1.5-8.el5 dovecot-1.1.4-0_81.el5 With assistance from Rainer Frey (Inxmail GmbH), I am able to successfully use client ssl certs for imap access on both my Nokia e61i and Thunderbird 2.0.0.17, problem now is dovecot sasl and postfix smtp authentication.

[Dovecot] dovecot delivery log
by jalal 22 Oct '08

22 Oct '08

Trying to debug a delivery problem recently (with Postfix) and I realized that Dovecot wasn't logging any of the delivery information. I'm using Postfix to recieve mail, which is passing it on to Dovecot's deliver to actually deliver the emails into the mail boxes. In dovecot.conf, I have: protocol lda { log_path = /var/tmp/dovecot-deliver.log } [root]# dir /var/tmp/ total 2 drwxrwxrwt 2 root root 1024 Oct 22 12:30 . drwxr-xr-x 24 root root 1024 Aug 5 08:03 .. -rw------- 1 vmail vmail 0 Oct 22 12:11 dovecot-deliver.log The log file gets created OK, but then stays at zero size. Using: Postfix 2.3.3 Dovecot 1.1.4 (and previously 1.0.9) Any clues as to how I can have a delivery log?

[Dovecot] displaying IMAP folders that are in ~/mail/ at same level as inbox
by David London 22 Oct '08

22 Oct '08

Hi, We are moving our current IMAP based system to a new one with dovecot All I can get about the current IMAP (imapd) system is: IMAP4rev1 v12.264 dovecot version is: 1.0.rc15 In the existing system I can see IMAP folders that are in ~/mail/ with many mail clients (e.g. Thunderbird, Outlook, Seamonkey and horde). These folders are presented in the client software as being at the same level as the inbox - i.e. not inside the folder "mail" On the new system, horde webmail shows the other folders in ~/mail/ as being at the same level as the inbox. But ... all the other mail clients above now show a folder (directory) called mail with the imap folders inside. Is there some way to set this up so these other mail clients see the imap folders in ~/mail/ as being at the same level as the inbox as we have on the old server? Thanks, David _________________________________________________________________

[Dovecot] Permission issues with subscriptions
by Eric A. Bonney 22 Oct '08

22 Oct '08

I am having some permission issues with my setup and I can't see where to make the change in the configuration files. My users can not create folders at all from their email clients nor from the web interface. I have noticed that each time I try to create a folder the subscriptions files permissions are set to 000. If I go back and reset the permissions to rw-r--r-- then everything is fine until I try to add another folder. running dovecot -n produces the following: # 1.0.10: /etc/dovecot/dovecot.conf listen: [::] login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login verbose_proctitle: yes first_valid_uid: 1000 default_mail_env: maildir:/mnt/hd4/MailBoxes/%d/%n mail_location: maildir:/mnt/hd4/MailBoxes/%d/%n umask: 511 auth default: user: nobody passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: prefetch I am guessing that Dovecot is the actual process that is creating the folders on the IMAP server, so where inside the configuration file do I set the permissions for the new folders along with the user and groups? Thanks, -Eric

[Dovecot] Proxying pop3 sessions into an imap one.
by Diego Liziero 22 Oct '08

22 Oct '08

I know it seems at least unusual. But I would like to know if someone knows a software that can proxy multiple pop3 and imap connections to the same account and use only imap connections to the real server. I need it because I've to deal with two pieces of software that are out of my control: - 1 - A certified mail provider that states something that I would like to know if it's really true, or if it's worth keeping like a funny signature: "multiple imap sessions are possible. When an imap session is active, no pop3 connections are possible on the same account; when no imap connection is active, only one pop3 connection at a time is possible on the same account. This is a limitation of the pop3 protocol." - 2 - A software written to deal with certified mails that supports only pop3 used by many people on the same account, (and the same account is used also by multiple imap mail readers). Regards, Diego.

[Dovecot] 1.2: Bug in listing of shared mailboxes with dot in user id
by Sascha Wilde 21 Oct '08

21 Oct '08

In dovecot 1.2 I can create a shared name space like this: namespace shared { separator = / prefix = users/%%u/ location = Maildir:/PATH/TO/spool/%%u/maildir:INDEX=/PATH/TO/spool/%u/maildir/shared_idx subscriptions = no } now, when I subscribe to a shared mailbox of another user with an dot in the users id, like: users/2(a)example.com/INBOX/foo and I list my subscribed mailboxes I get: l001 lsub "" "*" * LSUB () "/" "users/2@example/com/INBOX/foo" as you can see the dot in the user-id got normalized to the hierarchy seperator `/' -- which of cause is wrong. ;-) cheers sascha -- Sascha Wilde OpenPGP key: 4BB86568 http://www.intevation.de/~wilde/ http://www.intevation.de/ Intevation GmbH, Neuer Graben 17, 49074 Osnabrück; AG Osnabrück, HR B 18998 Geschäftsführer: Frank Koormann, Bernhard Reiter, Dr. Jan-Oliver Wagner

[Dovecot] Reporting NFS quotas via IMAP
by Edgar Fuß 21 Oct '08

21 Oct '08

I'm confident that the question has been asked before, but I can't remember the answer. I have -- dovecot 1.1.2 -- Mail storage (maildir format) on NFS -- Quotas on that file system -- A working rquotad -- mail_plugins = quota imap_quota in the protocol imap section -- quota=fs in the plugin section I get (using Apple Mail as a client) -- Notification that the account supports quotas -- No information about the size of the quota nor the usage I probably do something stupidly wrong. The WIKI tells me that fs quota support RPC (i.e., rquotad), so I'd expect my client to report the quota to me. Using quota(1) on the mail server works as expected.
