[Dovecot] Testing sieve filter
by Cliff Meece 28 Sep '07

28 Sep '07

Hi, I am trying to get sieve working with dovecot. Dovecot itself is working fine, and I have the following config: root@master:/var/log# dovecot --version 1.0.rc2 root@master:/var/log# dovecot -n # /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap ssl_disable: yes disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login mail_extra_groups: mail default_mail_env: maildir:/var/mail/%u auth default: passdb: driver: pam userdb: driver: passwd I have this in my lda protocol: mail_plugins = cmusieve And I have created a .dovecot.sieve in both ~ and /var/mail/$user/ that looks like this: require "fileinto"; if exists "X-Spam-Flag" { fileinto "Junk"; } No mail gets moved to the junk folder, nut it does arrive in my inbox with the X-SPAM-Flag: Yes header. How do I troubleshoot this? I don't see anywhere in the logs any errors or any mention whatsoever of filtering activity or failure. I have seen numerous pages on how to set this up, but they invariably focus on setting up virtual users, which I do not need, so it isn't clear which steps I can safely ignore. thanks in advance, Cliff

I'll upgrade if I need to, but that is the most current dpkg for my distribution, and I'd really rather not compile from source if I don't have to.

[Dovecot] Documentation to create plugins.
by "Fábio M. Catunda" 28 Sep '07

28 Sep '07

hi! Is there any documentation to guide me how to create a dovecot plugin? I'm trying to read the code, but I'm not a good C programmer. I have been able to copy the mail-log plugin into copy-log, edited about 4 lines of code, then I edited Makefiles and configure, now I'm able to compile, install and use my "new" plugin. Anyway, any help is appreciated. Thankz! !DSPAM:46fd34b1153407177711712!

I have it (deliver) in a restricted access folder as a standard safety precaution, but as most of these "jails" end up being only safe for a short time I have again gone back to using Postfix as the deliver. Timo has from time to time mentioned that he was thinking that deliver needed to be rewritten. hmmm. I still give you and Rich credit though, if you had not mentioned the ideas behind Sendmail and LDA, it would most likely taken much longer before I read that wiki entry and gave that approach a try, instead of trying to find the missing setting for changing groups that the error message wants fixed. > -- > Bill Cole > bill(a)scconsult.com > > > > ------------------------------ > > Message: 7 > Date: Thu, 27 Sep 2007 17:07:28 -1000 (HST) > From: Julian Cowley <julian(a)lava.net> > Subject: [Dovecot] Dovecot raw backtrace when copying to folder > To: dovecot(a)dovecot.org > Message-ID: <alpine.LRH.0.9999.0709271646190.28814(a)taurus.cesta.com> > Content-Type: TEXT/PLAIN; format=flowed; charset=US-ASCII > > Seeing a problem with a certain user causing dovecot to crash when > copying > mail to a folder.

[Dovecot] dovecot IMAPS + kmail
by Timothy Murphy 27 Sep '07

27 Sep '07

I notice that kmail does not allow an IMAP sub-folder to be created (from an IMAPS client). When I try, kmail says this cannot be done for one of the following reasons: Your access permissions may be inadequate to perform the requested operation on this resource. The location where the folder was to be created may not exist. A protocol error or incompatibility may have occurred. Is there any simple way of getting round this? KMail has no problem creating top-level IMAP folders.

[Dovecot] filtering when mail is moved to IMAP Inbox
by Rahul Amaram 27 Sep '07

27 Sep '07

Hi, I have been looking for a solution to this problem for quite sometime but just haven't got any. This is how my current set up is. I have a IMAP Server installed on my home server. It has various folders. I have configured Thunderbird in my laptop to connect to the IMAP Server and access mails. I have also configured Thunderbird to download mails from my GMail account using POP3. I have set up a filter in Thunderbird to move all my mails which come to my Local Folders "Inbox" to my IMAP Server's Inbox. Now here is my question - Is it possible to set up some rules in the IMAP Server (maybe sieve) so that I can filter the messages coming to its Inbox and move them to another folder? The whole idea is that I have control over when I want to fetch mails from my GMail account but at the same time the filtering rules for moving to custom folders should be stored on the server so that i do not replicate this in every client. Regards, Rahul. -- http://rahul.amaram.name

[Dovecot] blackberry with imap idle and concurrent connections
by Chris Tirpak 26 Sep '07

26 Sep '07

Hello - I've combed the wiki and archives a bit and can't seem to find what I am lookng for. It seems that BlackBerry Internet server has an issue with IMAP accounts along with IDLE and concurrent connections. Please see the following link (sorry it's fairly long): http://www.blackberry.com/btsc/search.do?cmd=displayKC&docType=kc&externalI… It appears as though IDLE can be implemented without "concurrent connections". Courier appears to do this although they have an option to turn it on. At first blush it seems obvious that any mail server will permit concurrent connections but as I read the docs for Courier and BlackBerry it appears to be a subtle thing whereby IDLE allows more than one connection to IDLE against the same IMAP folder when using maildir. Does Dovecot support his? Also, if anyone on the list has experience running a BlackBerry against Dovecot, are you currently getting instant (or near instant) notifications? If so what service are you using? T-Mobile? I am considering upgrading and using Dovecot but BlackBerry support has become critical. Thanks in advance. Chris

[Dovecot] Moving email from a folder to another using IMAP is very slow (sometimes)
by Stefano Scalise 26 Sep '07

26 Sep '07

Hi to all, I am using the new beta release 1.1. I am experiencing, after the upgrade to the 1.1beta some problems regarding the following scenario: I am conneted with Outlook to dovecot server using IMAP. I have many folders and I want to move an email from a folder to another using drag and drop. I see that when I move the email, the IMAP process goes to 90-95% for about 5 seconds and after, the mail is finally moved. I noticed that this operation sometimes (20% about) is again fast. There is no problem of overload of the server because this mail server, at the moment, manage just 1 email address. Before the upgrade to 1.1beta, this operation was very very fast. Is there a way to try to debug the IMAP process for understanding what is happening? Thank you for your help. Stefano.

[Dovecot] user_global_uid and user_global_gid
by Stefano Scalise 25 Sep '07

25 Sep '07

Hi to all, I am using the new beta release 1.1. I see that parameters user_global_uid and user_global_gid are no more used in dovecot-ldap.conf. That means that, as I use LDAP as backend I am obliged to se t these two fileds in LDAP for each user even if they are always the same, as I use virtual domains. I see that I can set the in dovecot.conf the parameters mail_uid and mail_gid, but even if I set these parameters, when I do the query in LDAP (for retrieving other useful parameters) I have the error: userdb(<email address>) didn't return uid but... I don't want to take uid parameter from LDAP, I want to set it globally but I still want to do an LDAP query. Is there a way to do this in the new evrsion or I cannot do anymore this? Thank you, Stefano.

[Dovecot] v1.1.beta1 released

http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta1.tar.gz http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta1.tar.gz.sig Alpha6 seemed to finally work quite well, so I think it's time for a feature freeze (except for dbox changes). I started a new wiki page to list incompatibilities between v1.0 and v1.1: http://wiki.dovecot.org/Upgrading/1.1 Fixes since alpha6: - deliver + maildir caused "UID 0 in transaction log" errors - deliver + maildir no longer blocks if dovecot-uidlist.lock file exists. The mail is simply delivered without updating uidlist or indexes. - Quota handling fixes, especially dict quota - etc.

[Dovecot] pam session=yes with gssapi authentication

hi there I noticed the following behaviour with auth backend pam and "args session=yes *" configuration: - login with "plain": pam session gets opend - login with "gssapi" (kerberos): pam session isn't opend (-> no $HOME will be created) Is this a bug or just a limitation by GSSAPI (maybe gssapi works around PAM)? - Thomas Dovecot Versions seen this: - 1.0.rc15 (Debian 4.0 Etch) - 1.0.0 (Debian backports)

I find the statement that dovecot has maildir format support misleading. By maildir support, I mean that mail is contained in directories ~/Maildir/inbox/[cur,new,tmp], ~/Maildir/Family/[cur.new.tmp], ~/Maildir/Finance/[cur,new,tmp], etc. This is the setup created if one runs kmail as mail client, specifying that one is using maildir format, and using the GUI to create new folders Family, Finance, etc. As far as I can see, if you now set up an IMAP server using dovecot on this machine, setting mail_location = maildir:~/Maildir/ in /etc/dovecot.conf then the email in the folders Family, Finance, etc will not be seen by an IMAP client. > But as soon as you have an e-mail klant using a non-supported mailbox > format *or* that is storing mail folders in a supported format but in > a non-standard place, tour theory applies, yes. What is the "standard" place for mail folders? > See also <http://wiki.dovecot.org/> for more info about this all. I've studied that wiki, and not found clear information on this point. To clarify my question, suppose one has email organised in server X as described above, in directories ~/Maildir/Family/[cur.new.tmp/ , etc. And now suppose one wants to access this email from laptop Y. How exactly does one have to change the setup on machine X? And what does one set mail_location to? It seems to me that this is an issue likely to be faced by anyone wanting to run a small home network. reading email on various machines, and wanting this email to be kept "in sync". Maybe dovecot is not a suitable program for this purpose?

Wow! I'm running 1.1 Beta 1 on OpenSuSE linux 10.2. It seems not bad at all.

Either grow the limit or change login_max_processes_count and max_mail_processes settings Where does dovecot take this 1024 fd limit?

When I telnet to port 110 (dovecot/POP3) after I enter correct user/pass I always get: telnet 10.9.0.80 110 Trying 10.9.0.80... Connected to 10.9.0.80. Escape character is '^]'. +OK Dovecot ready. USER maurizio(a)example.com +OK PASS mypass -ERR [IN-USE] Internal login failure. Refer to server log for more information. Connection closed by foreign host.

[Dovecot] Deliver, sendmail & envelope From_
by Rich Winkel 25 Sep '07

25 Sep '07

Sorry, couldn't find this in the archives. Under freebsd 4.x, the native mail.local that sendmail uses by default writes From_ lines that include the origin address. This is very readily parsable and handy for quick greps in mboxes. But deliver defaults it to MAILER-DAEMON. I see you can specify the envelope From_ with "-f", but I'm not sure how that's useful. Also I'm trying to figure out the instructions for making deliver the default delivery program under sendmail. This is a very plain vanilla setup I have here, procmail is not configured into sendmail.cf so I'm not sure how to adapt the instructions at wiki.dovecot.org/LDA/Sendmail Any help would be much appreciated. I've appended my local mailer stuff below. Should I just substitute deliver's path for mail.local? By the way, dovecot is very slick! It should speed up my mail server by a huge factor. Many thanks to Timo!

[Dovecot] Unknown dict module: db
by Lars Stavholm 24 Sep '07

24 Sep '07

Using dovecot-1.1beta1 I get "Unknown dict module: db" when starting up dovecot. In dovecot.conf I've got the "expire_dict = db:/var/lib/dovecot/expire.db" statement in the plugin{} section. Aparently required when the "expire" plugin is enabled. dovecot is built with "--with-db" and db-devel is present at compile time. Any ideas anyone? Cheers /Lars

[Dovecot] deliver copies "^From " header lines when delivering to Maildir
by pod 24 Sep '07

24 Sep '07

deliver appears to copy "^From " header lines from stdin when delivering to Maildir. The header filtering in mbox-save.c prevents this when delivering to an mbox and instead a synthesized "^From " header is written. This is an issue when using, for example, Postfix and mailbox_command = /usr/libexec/dovecot/deliver which does not appear to have an option not to write a "^From " header on the mailbox_command input. I'm attaching a patch that adds a save_header_callback() along the same lines as in mbox-save.c but I'm really not sure this is the right way to do it.

[Dovecot] IMAP: Disconnected: BUG: Unknown internal error (Dovecot 1.0.3)

Hi, I am getting the following error in the server mail logfile: > Sep 2 18:39:44 h648123 dovecot: IMAP(<account>)(<PID>): Disconnected: BUG: Unknown internal error (mail_debug is on, but there is not really much context for this in the log file, ie. no log events for several minutes, and then it appears, all of a sudden).

The client connection is simply closed. I am not getting a core dump for this; I am not sure whether I am supposed to. I configured Dovecot according to the instructions at http://www.dovecot.org/bugreport.html and core dumps generally work on my system, eg. I can force one using 'kill -s SIGSEGV <PID>' (where <PID> is a PID of one of the imap processes). What do I do with it? I am running Dovecot 1.0.3 (compiled from sources) on Suse 9.3. The client is The Bat! 3.99.x Professional. Client is allowed to open several concurrent connections to the IMAP server.
