[Dovecot] Slight problem with dovecot + IMAP
by Timothy Murphy 02 Oct '07

02 Oct '07

I'm running dovecot on my desktop with kmail as IMAP client on my laptop. When I start kmail on the laptop it sometimes takes several minutes to "calm down". The number of messages listed in the IMAP inbox increases greatly - maybe from 2500 to 3000 - and then slowly decreases. There are sometimes a large number of duplicate messages, which kmail allows one to delete. I don't know if this is a kmail or dovecot problem. It is quite likely there is something wrong in my setup. Any suggestions or advice gratefully received.

[Dovecot] IMAP Fetch fails with BAD instead of NO
by Reinier Bezuidenhout 02 Oct '07

02 Oct '07

Hi, I'm running version 1.0.3 of dovecot using IMAP and using javamail to access the mail. The application I'm using (when stress testing the system by doing simultaious creation of email and deleting emails, it sometimes get into the state where the application (via javamail) ask for the UID of a message that has been expunged and deleted (no longer exists). Dovecot returns with the following error: AXXX FETCH 14 (UID) AXXX BAD Error in IMAP command FETCH: Invalid messageset This can easily be reproduced by using telnet to 143 and giving the command by hand. When I read through the source code, there were obvious comments that states the dovecot will not return NO on fetch errors, only BAD. So I assume it is done on purpose. My question is that in RFC 3501 for fetch it says: (section 6.4.5) Result: OK - fetch completed NO - fetch error: can't fetch that data BAD - command unknown or arguments invalid No I guess a UID that is out of range could be considered "arguments invalid", but shouldn't it be a soft error with NO as a result where "can't fetch that data" is more appropriate according the the RFC. The command isn't syntactically BAD, the requested data just does not exists. The same command tested against another IMAP server returns AXXX NO message not available Not that they are necessarily correct, but it just begs the question.

Re: [Dovecot] Moving email from a folder to another using IMAP isvery slow (sometimes)
by Stefano Scalise 02 Oct '07

Hi to all, very strange! I tried to debug why imap process takes 100% CPu and it is very slow when I move an email from an imap folder to another imap folder and then I typed: strace -tt -o /log-imap.txt -p <process number> well, during the trace the imap process doesn't crash and it is very fast. If I stop the tracing, I have again the problem and sometimes the crash of the process. Any help?

[Dovecot] plugin problem
by Lars Stavholm 02 Oct '07

02 Oct '07

I'm trying to do a rewrite of the dspam_plugin for dovecot 1.1b1. There are some API changes that warranted an update of the plugin. Also, I wanted the dspam_plugin to be able to handle pristine mails for dspam retraining, as opposed to the signature based retraining. Question: How can I retrieve the full unix path for a specific mail? The original code uses mail_get_first_header() to retrieve the signature header. I need something like mail_get_mail_file_path(&path) which I then could pass on to dspam. Is there some such function available? Thanks in advance /Lars

[Dovecot] shared mailboxes question
by Cory Coager 01 Oct '07

01 Oct '07

I'm using a virtual mailbox setup. Lets say my users have mailboxes in /home/vmail/domain/%u. What I'm trying to do is setup one namespace that points to /home/vmail/domain and contains everyones mailboxes that I can subscribe to. Is this possible? I tried using a symlink to /home/vmail/domain but it doesn't work because its looking for the dotFoldername. The only way I could get this to work is by creating a symlink for each folder in every mailbox. This is way too much maintenance especially since it will dynamically change. The only other way I could get it working was to create a namespace for each user and point to /home/vmail/domain/%u/Maildir/. Then inside everyones Maildir/ create a symlink for INBOX -> . This works but I'd have to do it for each user when I'd rather just use one namespace. Is there an easier way of doing this?

[Dovecot] Opinions on preferred namespace?
by Ed W 01 Oct '07

01 Oct '07

Hi Any opinions on a preferred namespace setting for use with Dovecot? Deciding factors seem to be client support, not being too unusual, accidental ease of setup, wider character range support (eg dots in folder names?), issues when scripting imap commands? For example Outlook Express (common with our userbase) seems to assume no folderprefix when using our current Courier server and from memory I think this causes some subtle issue with Sent Items and Drafts folders until you tell it to use an INBOX. folder prefix? (can't recall the exact details right now) I notice also that Thunderbird will show all folders under "Inbox" if I have an INBOX. prefix, but shows them all in a list if there is not one. Actually I find the former quite a useful feature because I have a number of test accounts where I only want to click into the INBOX, do I can keep the list of folders closed up Any other programs exhibit any (possibly beneficial) side effects from different prefix choices? Anyone got any preferences either way? Any pros/cons in using a dot as folder separator rather than a slash? I can see some logic in using an INBOX folder prefix and a slash as the folder separator because this would then mimic the on-disk layout.. (Is this what cyrus does?) I mainly care about best support for Outlook Express / Windows Mail and Thunderbird - any opinions on most compatible settings? Cheers Ed W

Correct. If the folder does not exist, maildrop will create it on first delivery. If the end user deletes the folder, maildrop will recreate the folder on the next message delivery to that account.

[Dovecot] 1.1b1 initial pop3 login: assertion failed

Currently running 1.0.2 with 1.1b1 listening on a different port. On first pop3 login on 1.1b1 I received an immediate disconnect (I was testing with telnet) with the log entries below.

[Dovecot] v1.1.beta2 - maildir quota calculation problem
by Andrew Pavlenko 01 Oct '07

01 Oct '07

I have a problem with the maildir quota plugin. Any imap operations cause the plugin to recalculate the mailbox size and put the new value in the second line of the maildirsize file, while the third line always contains the size of the latest operation. So the resulting sum is incorrect. Moreover, quota-warning is not working either. Have anybody else met such problem? mail# ./dovecot -n # 1.1.beta2: /usr/local/etc/dovecot.conf ... mail_plugins(default): quota mail_log mail_plugins(imap): quota mail_log mail_plugins(pop3): quota mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 ... plugin: quota: maildir quota_rule: *:storage=10240 quota_warning: storage=75%% /usr/local/etc/quota-warning.sh 75

[Dovecot] Mixed Courier POP3 and Dovecot IMAP environment
by Jan van den Berg 01 Oct '07

01 Oct '07

Hi, Currently we support Courier POP and IMAP for all our users (users can use IMAP as well as POP at the same time). We are thinking about moving to Dovecot; but first moving away from Courier IMAP to Dovecot IMAP (and maybe later also move to Dovecot POP). This would create a mixed environment; after some research I have the following questions. To not break POP3 Courier and still be able to use Dovecot IMAP: - I have to use the namespace prefix in the dovecot.conf file: I read this in the wiki. - "Patch" the source so Dovecot IMAP will look for/use 'courierimapuiddb' instead of 'dovecot-uidlist': otherwise I guess POP3 and IMAP users will have different UID files, right? Is this smart or will this still break the UID file? - "Patch" the source so Dovecot IMAP will look for/use 'courierimapsubscribed' instead of 'subscriptions' of should I just go with the renaming of the files? I'm thinking about patching so the transition can be as transparent as possible: Also if anything might go wrong in production I want to be able to switch back to the 'old' Courier IMAP (without renaming files etc.) Any thoughts on this? Cheers, Jan

I also did one more API change for mailbox_transaction_commit*(). There's probably something still wrong with SORT command, but other than that I've fixed everything that's been reported.

[Dovecot] Maildir ignore

[Dovecot] dovecot-dspam plugin & virtual users
by Wicher Minnaard 30 Sep '07

30 Sep '07

Hi list, hi Johannes, I'm trying to use the dovecot-dspam plugin ( http://johannes.sipsolutions.net/Projects/dovecot-dspam-integration ) with vpopmail's virtual users. All seems well, except for the fact that dspam should be called with '--user currentuser(a)currentdomain.com' at line 157 here: http://johannes.sipsolutions.net/Projects/dovecot-dspam-integration/beta7-c… For my needs, 'currentuser@currentdomain' could be taken as the login name I use for logging in to Dovecot. As I'm not a C-programmer by a long shot, I was wondering if one of you could help me use the bincimap-API to import the login name into a variable so I can use that variable to construct a suitable dspam-command. Hope this is possible! Regards, Wicher Minnaard

[Dovecot] dovecot dspam plugin using libdspam
by Andreas Schneider 30 Sep '07

30 Sep '07

Hi, I've found the dovecot dspam plugin and looked at the code. I forks and calls the dspam binary for every mail. I didn't like this behavior, so I've migrated it to use libdspam. The plugin still needs more love: * Use cmake instead of a Makefile * Make the spam folder configurable in the dovecot.conf * Code cleanup and more comments. Please test. Comments and patches are welcome ;) http://www.cynapses.org/tmp/dovecot-dspam-plugin-0.1.tar.gz Cheers, -- andreas -- http://www.cynapses.org/ - cybernetic synapses

[Dovecot] Problem with manually moving maildir files between folders
by Bill Landry 30 Sep '07

30 Sep '07

dovecot --version 1.1.beta1 With previous versions of Dovecot I could manually move maildir files between folders and the index would automatically update when entering the folder with Thunderbird. However, with 1.1.beta1, I am seeing the following when entering the folder, when attempting to rebuild the indexes via Thunderbird, or when attempting to force the download of all messages in the folder (this is with mail_debug = yes): Sep 30 09:05:55 mail dovecot: imap-login: Login: user=<bill(a)inetmsg.com>, method=PLAIN, rip=192.168.1.100, lip=192.168.1.37, TLS Sep 30 09:05:55 mail dovecot: IMAP(bill(a)inetmsg.com): Effective uid=1000, gid=1000, home=/var/spool/vmail/inetmsg.com/ Sep 30 09:05:55 mail dovecot: IMAP(bill(a)inetmsg.com): maildir: data=/var/spool/vmail/inetmsg.com/bill Sep 30 09:05:55 mail dovecot: IMAP(bill(a)inetmsg.com): maildir++: root=/var/spool/vmail/inetmsg.com/bill, index=, control=, inbox=/var/spool/vmail/inetmsg.com/bill Sep 30 09:05:58 mail dovecot: imap-login: Login: user=<bill(a)inetmsg.com>, method=PLAIN, rip=192.168.1.100, lip=192.168.1.37, TLS Sep 30 09:05:58 mail dovecot: IMAP(bill(a)inetmsg.com): Effective uid=1000, gid=1000, home=/var/spool/vmail/inetmsg.com/ Sep 30 09:05:58 mail dovecot: IMAP(bill(a)inetmsg.com): maildir: data=/var/spool/vmail/inetmsg.com/bill Sep 30 09:05:58 mail dovecot: IMAP(bill(a)inetmsg.com): maildir++: root=/var/spool/vmail/inetmsg.com/bill, index=, control=, inbox=/var/spool/vmail/inetmsg.com/bill Sep 30 09:05:58 mail dovecot: IMAP(bill(a)inetmsg.com): open(/var/spool/vmail/inetmsg.com/bill/.SURBL/cur/1190901367.M206487P27879V… failed: Permission denied Sep 30 09:05:58 mail dovecot: IMAP(bill(a)inetmsg.com): Disconnected: Internal error occurred.

[Dovecot] Log file name too with mail_log
by "Fábio M. Catunda" 30 Sep '07

30 Sep '07

Hi! Is there a way to log the file that have been copied when a person move it from a folder to another using mail_log? Actualy this is what I get in logfile: dovecot: 2007-09-27 15:15:33 Info: IMAP(user(a)mydomain.com): copy -> Spam: uid=101, msgid=<46FBC6C9.1060301(a)somedomain.com>, box=Dovecot What I would like to have is something like: dovecot: 2007-09-27 15:15:33 Info: IMAP(catunda(a)mydomain.com): copy -> Spam: uid=101, file=/cur/1190916950.P15981Q38M976125.mydomain.com:2,S, box=Dovecot I believe that its a pretty simple thing to do, but my C skills are null! Any help would be great. Thankz! !DSPAM:46fc21ce213771244520847!

[Dovecot] Subaddress Extension in sieve plugin
by Frank Behrens 30 Sep '07

30 Sep '07

Hello! With many MTAs it is possible to use a special form of adressing: subaddresses or "plussed addresses". For sendmail you can read some information on http://www.sendmail.org/m4/misc_features.html http://www.unix.org.ua/orelly/networking/sendmail/ch24_04.htm#SML2-CH-24-SE… In a sieve filter you can analyse these special detail values, the syntax is described in RFC3598 (http://tools.ietf.org/html/rfc3598) The current deliver with sieve plugin for dovecot seems to support this RFC, but has the detail information not available. If I use require ["subaddress", "fileinto", "reject"]; require "envelope"; if envelope :detail "to" "junk" { fileinto "junk"; } the rule is not triggered, because the detail information from envelope is not available. Deliver gets the user information only via command line switch "-d". I did not analyse the problem very deep, but I believe we should introduce a new command line parameter for deliver, so deliver can pass the detail information to the sieve plugin. With that parameter you are able to pass the detail information from sendmail to devecot's deliver in the same way procmail is handled (procmail uses -a parameter). To avoid confusion: deliver has already a parameter -m to specify a different mailbox. In the described case the mailbox should be determined by the sieve filter, not via command line parameter. Existing workaround: Because I need this functionality I wrote a quick (and dirty?) workaround. Sendmail does not call deliver directly, but a wrapper program, that adds an additional "Delivered-To" header line. So the detail information may be processed with if address :detail ["Delivered-to"] "junk" { but I would prefer to call deliver directly. What do you think, is it a useful extension and does it work?

[Dovecot] v1.1.beta1 POP3 delete problem
by arvids 30 Sep '07

30 Sep '07

Hello, POP3 server does not delete mails when user quits POP3 session, but only at the next login. It looks so - user logs in with USER and PASS commands, at this moment new messages are moved from /new to /cur maildir folder. Then messages are deleted with DELE command(before deleting there can be other POP3 commands) and the user quits session. The server says "+OK Logging out, messages deleted.", but in fact messages are not deleted from the disk and stays in /cur folder. And these messages are deleted only when user logs in next time. dovecot -n: # 1.1.beta1: /usr/local/dovecot/etc/dovecot.conf base_dir: /var/run/dovecot/ syslog_facility: local0 protocols: pop3 ssl_disable: yes disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/local/dovecot/libexec/dovecot/pop3-login login_greeting: Server. login_process_per_connection: no login_process_size: 64 verbose_proctitle: yes first_valid_uid: 95 first_valid_gid: 95 mail_uid: 95 mail_gid: 95 mail_location: maildir:~/Maildir mail_debug: yes fsync_disable: yes mail_executable: /usr/local/dovecot/libexec/dovecot/pop3 mail_plugins: quota mail_plugin_dir: /usr/local/dovecot/lib/dovecot/pop3 pop3_enable_last: yes pop3_client_workarounds: outlook-no-nuls oe-ns-eoh auth default: mechanisms: plain login digest-md5 cram-md5 apop cache_size: 2048 cache_ttl: 28800 cache_negative_ttl: 60 user: doveauth verbose: yes debug: yes debug_passwords: yes passdb: driver: sql args: /usr/local/dovecot/etc/dovecot-sql.conf userdb: driver: prefetch userdb: driver: sql args: /usr/local/dovecot/etc/dovecot-sql.conf socket: type: listen master: path: /var/run/dovecot/auth-master mode: 384 user: vmail group: vmail plugin: quota: dict:::proxy:/var/run/dovecot/dict-server:quotadict dict: quotadict: mysql:/usr/local/dovecot/etc/dovecot-sql-dict-quota.conf Regards, Arvids

[Dovecot] v1.0 vs 1.1b re: Postfix and Dovecot LDA
by Jerry Yeager 30 Sep '07

30 Sep '07

In running the various 1.0.n versions of Dovecot's LDA with the instructions in the wiki for using LDA with Postfix [on OS X 10.4] things went well using the instructions as-is (no setuid problems). This changed in moving over to the 1.1 beta. The LDA refused to work failing with the error "setgroups() failed: Operation not permitted" as I mentioned in a previous message. After reading the exchange between Bill Cole and Rich Winkel and following up on this, it seems that the new 1.1b wants you to give the Deliver app specific setuid permission via: cd /path/to/where/dovecot's/deliver/is sudo chmod u+s deliver Then things worked as before. There was no need to give the group 's' permission nor to change ownership of deliver from the default root:staff or root:wheel or whomever... . The error message seems odd though. I am not sure if, overall, this means there is a problem in Dovecot 1.0.n or that things are being tightened up in 1.1b. Thanks Bill and Rich for the tip! Jerry Yeager

I don't see this as a problem at all (why create one when there's none to be found:): * Move message into Spam: it's a spam that should be reclassified. * Move message out of Spam: it's a ham that should be reclassified. Don't really care where the mail comes from or where it is moved. This is the beauty of it all, count the key or mouse clicks, can't be less than this:) * Using the expire plugin, the Spam folder will be emptied auto- matically in due time (typically 30 days maybe) without user intervention. All close to zero maintenance for sysadmin as well as end-user. > Well, by now I dont have much, but I really would like to know how to > find the filename of a message being copied from a folder to another. No such luck (I think): to my understanding (with the help of Johannes in previous reply in this thread), you'd have to create a temporary file with the mail message using tmpnam() + mail_get_stream() or similar, and then do your thing. I'm aiming towards that exact functionality: I want to be able to do training using "pristine" source (so I'll need the whole message), and keep the previous functionality using signatures. We'll see how it goes. Good Luck and thanks for your input /Lars

[Dovecot] Configure/install path overrides
by Remy Zandwijk 30 Sep '07

30 Sep '07

Hi, I'm building and installing dovecot on a Solaris 10 machine and therefore I want to install Dovecot in /opt/dovecot. Thus, I start configure with --prefix=/opt/dovecot. I also override things like 'libexecdir', 'docdir', etc. When calling make install, Dovecot is installed in /opt/dovecot, but for example the binary user files are installed in /opt/dovecot/bin/dovecot. The same for the docs, which are installed in /opt/dovecot/share/doc/dovecot. I think that's not quite nice and neat, so I call 'make install' like: make docdir=/opt/dovecot/share/doc install. But even then, the wiki stuff is still installed in /opt/dovecot/share/doc/dovecot/wiki in stead of /opt/dovecot/share/doc/wiki. Very anoying. My point is that ./configure should be able to override all paths, but since some paths are somehow hard-coded in the Makefile, this is impossible. Any chance this will (be) change(d) sometime? -Remy

[Dovecot] deliver w/quotas - MDN after accept mail?

I'm testing deliver with sendmail and fs quotas. On an over quota condition, deliver accepts the mail, deletes it, then issues a MDN immediately. Is there a way to get deliver to soft fail like procmail does with a 400 error and queue the mail, then let sendmail handle the MDN, following it's "confTO_QUEUEWARN" and "confTO_QUEUERETURN" ? Thanks, Ken -- Ken Anderson Pacific.Net

[Dovecot] Testing sieve filter

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 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.

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] Password auth with Postfixadmin & MySQL

I am trying to get Postfix, Dovecot, Postfixadmin, and MySQP all working together. I'm using 1.0.5 atm. I've hit a point where I can't seem top get dovecot to auth to the MySQL password database It seems to see the user OK, but I can't seem to get a password match.

[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

25 Sep '07

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
by Thomas Mueller 25 Sep '07

25 Sep '07

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?

[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] What is your dovecot setup?
by Timothy Murphy 24 Sep '07

24 Sep '07

I'd be really grateful if someone running a dovecot IMAP (or IMAPS) server could tell me exactly how their email folders are arranged. What is the mail_location setting in /etc/dovecot.conf ? What are the directories (or some of them) containing mail messages? Does the client see an inbox folder? If so, what directory on the server contains these email messages?

[Dovecot] SEARCH NOT not working
by Julian Cowley 24 Sep '07

24 Sep '07

I think I've found the source of a bug which I first saw when running dovecot and pine (or alpine), which I finally tracked down by doing a protocol trace. In the IMAP session, the SEARCH command appears to have a problem with sets of messages and/or the NOT operator. Probably the best way to show this is by doing operations on a folder with ten messages in it. a select ten * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 10 EXISTS * 0 RECENT * OK [UNSEEN 1] First unseen. * OK [UIDVALIDITY 1190450101] UIDs valid * OK [UIDNEXT 11] Predicted next UID a OK [READ-WRITE] Select completed. Now, start doing some basic searches using message sets: b search (1:10) * SEARCH 1 2 3 4 5 6 7 8 9 10 b OK Search completed. OK, so far so good. Try the inverse: c search not (1:10) * SEARCH c OK Search completed. OK. d search not (1,10) * SEARCH d OK Search completed. Hmm, should have output 2..9. e search not (2,10) * SEARCH 1 e OK Search completed. Hmm.. that should have been 1, 3..9. f search not (2:10) * SEARCH 1 f OK Search completed. OK, expected. g search not (1,9) * SEARCH 10 g OK Search completed. Seems to affect other end of the range as well. h search not (2,9) * SEARCH 1 3 4 5 6 7 8 10 h OK Search completed. OK working again.

[Dovecot] dovecot with virtual and local users?
by Patrick Winnertz 23 Sep '07

23 Sep '07

Hello, I googled for a while in order to find a solution to make dovecot work with local and virtual users. My Mailserver setup looks like the following: virtual users are stored in a mysql database, and having their Mailbox here: /srv/mail/$domain/$uid/ Local users have a Maildir folder in their home directory. The only point i found in the web concerning this issue is this post here: http://www.dovecot.org/list/dovecot/2006-November/017478.html but I failed to understand the user_query. Can somebody who has such a setup running, or know how such a setup will work give me an advice, or a good point to read? Greetings Patrick ps: Please cc me, I'm not subscribed. -- .''`.

[Dovecot] kmail + IMAPS
by Timothy Murphy 23 Sep '07

23 Sep '07

I have dovecot IMAPS + kmail working perfectly on two laptops - I'm using one now - but I just tried starting it on a third laptop, and cannot get it running; kmail on the third laptop just waits indefinitely, saying "Retrieving Folder Contents Please wait ...". All 3 laptops are running Fedora 7, with more or less the same packages, all updated. (1) I suspect the problem lies with authentication. But how can I test this? Running "telnet <server> 993" gets the same response on all 3 laptops: [tim@elizabeth ~]$ telnet www.*.com 993 Trying 86.*.*.228... Connected to www.*.com. Escape character is '^]'. with no further response until I press ^]. I looked at <http://wiki.dovecot.org/TestInstallation> but this seems only to apply to IMAP on port 143. (2) kmail has an option to "Check What the Server Supports" under the Security tag, but pressing this just returns without any message, leaving whatever settings as they are. (On the laptops where kmail is working as an IMAPS client, the settings are changed to "Use TLS ..." and "Clear text".) I realise this is probably a kmail question, but shouldn't clicking on this option return some warning if it does not work? (3) I guess I don't understand exactly how TLS authentication works. Does installing openssl set up the correct certificates on server and client? Is there any documentation on this? Any suggestions or enlightenment gratefully received.

[Dovecot] recipient delimiter results in sieve errors
by Gregory Mokhin 23 Sep '07

23 Sep '07

Hello, I'm using dovecot 1.0.3 and Dovecot Sieve plugin 1.0.2. Sieve script works fine with normal addresses, like user@domain.., and messages marked with "X-Spam-Flag: YES" are delivered directly to INBOX.Spam. To make deliver understand recipient_delimiter I tried two methods, the first one as per wiki (tweaking postfix master.cf), and the second one by tweaking dovecot-sql.conf (the main idea is to use concat(substring_index('%n',"+',1),'@','%d') for the username). Both methods work good. However when deliver processes sieve script for the addresses with a delimiter, user+ext(a)domain.tld, there is an error: deliver(test@k..): Info: cmusieve: Using sieve path: /home/vmail/.dovecot.sieve deliver(test@k..): Info: cmusieve: Executing script /home/vmail/.dovecot.sievec deliver(test@k..): Info: sieve runtime error: Keep: Generic Error deliver(test@k..): Error: sieve_execute_bytecode(/home/vmail/.dovecot.sievec) failed deliver(test@k..): Info: msgid=<..@mail...>: saved mail to INBOX In that case message is delivered to INBOX, not to INBOX.Spam Regards, Gregory

Then there are a few files from Cyrus as well which contain: * 4.

Currently these copyrights or acknowledgments aren't listed anywhere else than in the source files. I don't know if binary packagers have added those, but somehow I doubt it.

[Dovecot] IDLE with inotify problem
by Michael Guntsche 23 Sep '07

23 Sep '07

Hi, I recently switched from courier imap to dovecot. With courier I had a working IDLE setup that informed me immediately when new mail arrived. With Dovecot it is different, sometimes i get an immediate result but most of the time it takes a rather long time for the notification to return to the client. For testing purposes I set mailbox_idle_check_interval = 1 and i now get the same behaviour as with couier (a new mail immediately causes a notification) but i am not sure that this is the right solution. Reading the comments in the config files I was under the impression that this is not needed if dovecot uses inotify. Setup: Kernel 2.6.22.1 with inotify dovecot 1.0.3 from debian unstable Build options: ioloop=epoll notify=inotify ipv6 openssl So my question is can I check that dovecot is actually using inotify? Kind regards, Michael

[Dovecot] Problems with quota dict in 1.1.alpha4
by arvids 22 Sep '07

22 Sep '07

Hello, there are problems with quota dict when multiple dovecot deliver processes are launched in parallel. It can be reproduced by sending a mail with multiple different recipients - the mail is delivered OK to all recipients, but the quota are not updated correctly in sql. I looked at the code and it seems that the problem is somewhere in dict cache. If I configure in Postfix max number of deliver processes to 1, dict quota is updated correctly. postconf -n output: # 1.1.alpha4: /usr/local/dovecot/etc/dovecot.conf base_dir: /var/run/dovecot/ syslog_facility: local0 protocols: pop3 ssl_disable: yes disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/local/dovecot/libexec/dovecot/pop3-login login_greeting: Server. login_process_per_connection: no login_process_size: 64 verbose_proctitle: yes first_valid_uid: 95 first_valid_gid: 95 mail_uid: 95 mail_gid: 95 mail_location: maildir:~/Maildir mail_debug: yes fsync_disable: yes mail_executable: /usr/local/dovecot/libexec/dovecot/pop3 mail_plugins: quota mail_plugin_dir: /usr/local/dovecot/lib/dovecot/pop3 pop3_enable_last: yes pop3_client_workarounds: outlook-no-nuls oe-ns-eoh auth default: mechanisms: plain login digest-md5 cram-md5 apop cache_size: 2048 cache_ttl: 28800 cache_negative_ttl: 60 user: doveauth verbose: yes debug: yes debug_passwords: yes passdb: driver: sql args: /usr/local/dovecot/etc/dovecot-sql.conf userdb: driver: prefetch userdb: driver: sql args: /usr/local/dovecot/etc/dovecot-sql.conf socket: type: listen master: path: /var/run/dovecot/auth-master mode: 384 user: vmail group: vmail plugin: quota: dict:::proxy:/var/run/dovecot/dict-server:quotadict dict: quotadict: mysql:/usr/local/dovecot/etc/dovecot-sql-dict-quota.conf Regards, Arvids

[Dovecot] Feature Request for Proxy
by Ed W 22 Sep '07

22 Sep '07

Hi, Quick feature request for the proxy function: I have a couple of machines which are all customer facing and customer mailbox lives on any one of them. Customer can login to any machine and the proxy feature then forwards them to the correct machine (often the machine they are already connected to). However, right now if the SQL query simply returns the IP of the correct machine, and this happens to be the same machine that the connection is already on, then we get the auth process stuck in an infinite loop (and generating a lot of log files...) The quick fix is to customise each installation and add some kind of WHERE clause to change the results IF result is already the same as the machine we are on. However, this is error prone when setting up new machines and it's easy to forget or make a typo adjusting the config files. In my case I am using vservers and it's quite neat to be able to simply copy the whole image and fire it up on a new IP to test an upgrade, etc, hence easy to mess up adjusting the conf files when creating a new image. Any suggestions on how this could be done more dynamically, or else could I raise a feature request that the auth process somehow realises when it's being forwarded to an IP address that it's actually listening on already already (ie it's a request which loops back to itself), thus simplifying the config files? I haven't cracked open the code, but it sounds somewhat possible to check the list of IP addresses we are currently listening on and check that the proxy dest isn't among them? Cheers Ed W

[Dovecot] maildir rename_subfolders() and listescape interaction
by pod 22 Sep '07

22 Sep '07

I'd like to flag a problem we are observing that looks like it is caused by the listescape-plugin.c. I realize that this plugin is not part of the standard Dovecot 1.0 distribution but I would appreciate any insights or suggestions for fixes that anyone is kind enough to offer. The problem concerns subfolder renames when used in conjunction with Maildir folders (I've not tested this against any other folder type). Without listescape plugin: mail_location: maildir:%h/Maildir:INDEX=%h/index:CONTROL=%h/control mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota namespace: type: private separator: / inbox: yes 01 LIST "" * * LIST (\HasNoChildren) "/" "INBOX" 01 OK List completed. 02 CREATE a 02 OK Create completed. 03 CREATE a/b 03 OK Create completed. 04 LIST "" * * LIST (\HasChildren) "/" "a" * LIST (\HasNoChildren) "/" "INBOX" * LIST (\HasNoChildren) "/" "a/b" 04 OK List completed. 05 RENAME a c 05 OK Rename completed. 06 LIST "" * * LIST (\HasChildren) "/" "c" * LIST (\HasNoChildren) "/" "INBOX" * LIST (\HasNoChildren) "/" "c/b" 06 OK List completed. 07 LOGOUT * BYE Logging out 07 OK Logout completed.

Seemingly the only relevant log entry is @4000000046d70d8f1f72b66c dovecot: Error: IMAP(pod): rename(/srv/mail/home/test0/pod/Maildir/.a/b, /srv/mail/home/test0/pod/Maildir/.c/b) failed: No such file or directory Note the response to tag 05 in each case. The 06 list response in the listescape case is not unexpected given the nature of the failure. My initial reading of rename_subfolders() from maildir-storage.c suggests that the calls through maildir_mailbox_list_init() and maildir_mailbox_list_next() are returning "external" style names (i.e. ones that present "/" as the hierarchy separator) to rename_subfolders(), which is an "internal" helper function. This is supported by the logged error message. I am afraid I am yet to get my head around the actual code path and the escaping and unescaping that is going on so am not able to suggest a fix as yet.

[Dovecot] Multiple SSL certs
by Noah Kantrowitz 22 Sep '07

22 Sep '07

I am trying to find a way to have the SSL cert used by Dovecot be dependent on the local IP address. So far the only ways I have found is to either have two different instances running (annoying because I would need to argue with the init scripts a lot) or use the old, undocumented server{} sections. Is the latter an acceptable way to do this, or is there something better? --Noah Kantrowitz

[Dovecot] deliver assertion failure

[Dovecot] v1.1.alpha4 released / about dbox
by Timo Sirainen 22 Sep '07

22 Sep '07

http://dovecot.org/releases/1.1/alpha/dovecot-1.1.alpha4.tar.gz http://dovecot.org/releases/1.1/alpha/dovecot-1.1.alpha4.tar.gz.sig Lots of fixes since alpha3. Also includes the dbox rewrite. Currently dbox works properly only in one-message-per-file mode. I'm not actually even sure how good idea it would be to use it with multiple-messages-per-file mode. But I guess it won't hurt to finish its implementation and see. :) As you can see I haven't been replying much to the mailing list lately. My school started again, which meant that I had to start sleeping again at night instead of at day :) Doing that always takes a few weeks of feeling too tired to get much of anything done. Hopefully that goes away soon. A bit more about dbox: Originally I had thought that it'd be good to have multiple messages per file. The bad thing about that is that it works badly without fcntl locks, which don't work all that great with NFS. So I changed my plans a bit so that dbox also supports one-message-per-file behavior where it doesn't need locking much. (Multiple-messages-per-file is still supported by the format, but currently the code is not fully working.) dbox files begin with a header, then they have the message data and at the end of file there's a metadata block. Metadata contains things like message flags, keywords, received date and so on. When a flag/keyword is updated, the change is normally done only to index files. This is why dovecot.index and dovecot.index.log files are important with dbox format, they contain flag changes that haven't been written anywhere else. But since there's still a chance that index files could break (although v1.1 tries harder than v1.0 to fix problems), it would be nice if the flags/keywords were written to metadata block once in a while. So if the index files are lost, flag changes wouldn't be completely lost. Metadata updates of course use disk I/O so they shouldn't be done too often. I was thinking that the metadata could be updated: - if IMAP connection has been idling for 4 hours (not changing flags) - when closing mailbox and there are changes older than 4h - immediately if there are changes older than 24h (whenever mailbox is being synced, e.g. SELECT/NOOP/STATUS) Or something like that. Those rules can of course be changed, but I'm not sure if I should bother making them configurable from dovecot.conf. There are already too many settings.

[Dovecot] Unexpected input from auth master: CUID
by Branislav Baca 22 Sep '07

22 Sep '07

Hello, I'm using postfix(2.4.5) and dovecot(1.0.5), and till now I have been using postfix deliver agent. Now I have tried to reconfigure postfix to use the dovecot LDA, but I'm getting some strange error: Sep 9 18:07:57 hostname deliver(username(a)domain.tld): BUG: Unexpected input from auth master: CUID^I5 For IMAP and POP3 my configuration works fine. I have tried it also with dovecot versions 1.0.4 and 1.0.1, but the behaviour is the same. What can be the reason of this? What should I look for to get more details what can causing this? I have this line in postfix master file: dovecot unix - n n - - pipe flags=DRhu user=mails:mails argv=/opt/dovecot-1.0.5-1/libexec/dovecot/deliver -f ${sender} -d ${recipient} In main.cf: dovecot_destination_recipient_limit = 1 virtual_transport = dovecot Relevant parts of dovecot.conf: auth default { passdb sql { args = /path/to/dovecot-sql.conf } userdb sql { args = /path/to/dovecot-sql.conf } socket listen { client { path = /var/run/dovecot/auth-master mode = 0600 user = mails group = mails } } } protocol lda { postmaster_address = postmaster(a)domain.tld auth_socket_path = /var/run/dovecot/auth-master } And relevant parts of dovecot-sql.conf: driver = mysql password_query = SELECT address as user, passwd as password FROM mail_users WHERE address='%u' user_query = SELECT CONCAT('/home/',maildir) as home, 999 as uid, 999 as gid FROM mail_users WHERE address='%u' Thanks, BB

[Dovecot] Dovecot "authentication failed" interaction with Postfix
by Julian Cowley 22 Sep '07

22 Sep '07

Hi, I'm not sure if I should be posting this question here or on the Postfix mailing list, but I'll start here. When using Dovecot SASL with Postfix, is there a way to return a login-failed reason in the SMTP AUTH dialog using "nologin", similar to the way it can be done with Dovecot IMAP and POP? Details: I have a Dovecot authentication-only daemon working with a Postfix server doing SMTP AUTH. The Dovecot configuration uses a MySQL driver to get the password information, and one of the fields in the database is "access". In my SQL query, I return a row only if "access" is non-zero. This all works -- I can shut down an account from accessing mail while retaining the user's original password. password_query = SELECT username AS user, password FROM mailbox WHERE username = '%u' AND access != 0 Now, in my Dovecot IMAP and POP server configuration, I'm using "access" in a similar way, except that instead of not returning a row when "access" is zero, I return the "nologin" extra field (along with a "reason" field). The MySQL query for this is slightly tricky, but it works: password_query = SELECT username AS user, password, NULLIF(access != 0, 1) AS nologin, 'Access not allowed for this account' AS reason FROM mailbox WHERE username = '%u' While this second query works correctly with IMAP and POP authentication, it does not work with Postfix SMTP AUTH. Assuming the password is correct, the user is authenticated even when "access" is zero. It seems that either Postfix and/or dovecot-auth (I'm not sure which) is ignoring the "nologin" field in this case. In addition, when using the first SQL query, nothing is returned as a reason following Postfix's message. For example: AUTH PLAIN (correct password) 535 5.7.0 Error: authentication failed: <-- no reason returned here I'd like to return a reason here in the (optimistic :) hope that this will be shown to the user by the email client when an account is shut off. Here's an example of it working correctly with IMAP with an account that is shut off: 001 LOGIN user (correct password) 001 NO Access not allowed for this account

[Dovecot] Wrong size calculating with maildirquota
by Umut Arus 22 Sep '07

22 Sep '07

Hello, I'm using dovecot-1.0.5 with postfix. There is a problem which dovecot folder's size calculating wrong. It doesn't calculates whole folders' sum. Only maildirsize file keeps the first requested folder's size (in this example, Inbox). The example shows Inbox's size, another folder's size didn't add although connecting with IMAP. As the effect, I can not manage users' quota. Is there any hint with using namespace. Include quota size infos in control file, [root@xxxx Maildir]# cat /var/no-quotas/control/oneusername/maildirsize 512000000S 4941014 190 1849 1 40788 1 Also, namespace descriptions in dovecot.conf, namespace private { separator = / prefix = inbox = yes location = maildir:~/Maildir:INDEX=/var/no-quotas/index/%u:CONTROL=/var/no-quotas/control/%u } namespace private { separator = / prefix = mail/ #hidden = yes location = maildir:~/Maildir/.mail:INDEX=/var/no-quotas/index/%u:CONTROL=/var/no-quotas/control/%u } thanks in advance.

[Dovecot] Deliver parameter problem
by Umut Arus 22 Sep '07

22 Sep '07

Hello, I'm using dovecot-1.0.5 with postfix. I have to use deliver from procmail because I have some filters. There is no document about how to using deliver parameters (-d) other than http://wiki.dovecot.org/LDA . If I set -d parameters manually as a username everything is ok. I can not set users' mail quota (don't lookup) with mysql db if I haven't set -d parameter as receipt username in procmail. How can I describe user (-d) parameter's variable in procmail?

[Dovecot] Assertion failure in mail-index-view-sync.c
by Doug Council 22 Sep '07

22 Sep '07

I have been getting these assertion failures every couple days, killing the IMAP process. After it happens, I can login immediately and everything is fine until it happens again. Here is the log entry: Sep 10 10:03:41 mailbox-4 dovecot: nh: IMAP(username): file mail-index-view-sync.c: line 666 (mail_index_view_sync_end): assertion failed: (view->log_file_offset >= view->map->hdr.log_file_int_offset) Sep 10 10:03:41 mailbox-4 dovecot: child 38458 (imap) killed with signal 6 It started after I disabled indexing for deliver and IMAP: mail_location = maildir:~/Maildir:INDEX=MEMORY I removed the dovecot.index* files from all of the maildir directories (including the root/INBOX), but that didn't help. I have upgraded to 1.0.5, but that didn't help either. Any ideas as to what might be causing this? Thanks, -Doug

Hi. I am testing E-mail delivery by using dovecot 1.1 alpha6. But, The following message(syslog) is output while receiving mail. And, I'm try to looked for this reason in that source code. Hum... I think why the deliver is not using a 'MAILBOX_TRANSACTION_FLAG_ASSIGN_UIDS' flag. # deliver/deliver.c:142::deliver_save() function - calling mailbox_transactio n_begin() The imap's COPY/APPEND commands is using this flag.

[Dovecot] dovecot 1.1alpha6 deliver+quota bugs
by Andrew Garner 22 Sep '07

22 Sep '07

I was playing around with dovecot-1.1 and maildir++ quotas, and ran into a reproducible error with indexing. This only seems to be a problem for new maildirs. If I send a message without the quota plugin on, and "seed" the index/control files, future deliveries with the quota plugin seem to succeed without errors.

[Dovecot] quota reporting and mail.app
by Mike Horwath 20 Sep '07

20 Sep '07

Hi everyone. I can't get mail.app to report back correct quota information using mail.app and dovecot (though it works with courier-imap). I am looking at migrating away from courier-imap to dovecot but this issue is something I need to have resolved <somehow>. Thunderbird is fine and reports back good info on either connection. I am off to read RFCs (can't I just read the sendmail book again? Might be easier...) to see what should really be done.

[Dovecot] SASL from remote server
by Daniel L. Miller 20 Sep '07

20 Sep '07

Is there a way, using Dovecot and Postfix, to use SASL from a remote server? Since it appears the communication uses Unix sockets, does this mean it is restricted to local services only? I have a two-server configuration, where my firewall also runs the mail gateway/filter (Postfix + ASSP). My internal server has Postfix + Dovecot. Right now I have my internal server configured to use Dovecot SASL, but the external server is still using the Courier authdaemon against the LDAP database. -- Daniel

[Dovecot] Running a script when a mail arrives
by Dennis Becker 20 Sep '07

20 Sep '07

Hi, I'm trying to execute a script when a mail arrives in a given user's mailbox. Something like .dovecot.sieve. The reason I'm not using sieve itself is that I need to do stuff on mail arrival, which is beyond sieve's features. So is there a way to tell dovecot to run a script when a mail arrives in a certain mailbox? Optionally a solution to forward the whole mail to a script would be good too. -- Dennis Becker

[Dovecot] Multiple Quota "ignore=" in Dovecot 1.0.x?
by Rich at Whidbey Telecom 20 Sep '07

20 Sep '07

Any chance that multiple "ignore=" statements cab be specified for a quota in Dovecot 1.0.x? We know this is possible in 1.1, but won't be able to update until it's stable. We've tried: quota = maildir:storage=256000:ignore=Junk:ignore=Trash and quota = maildir:storage=256000:ignore=Junk,Trash However, only "Junk" is ignored, and email can't be deleted when the mailbox is full. Thanks! Rich

Hello, hope guys someone can help me i have installed mailserver according this tutorial http://johnny.chadda.se/2007/04/15/mail-server-howto-postfix-and-dovecot-wi… which is linked from dovecot maunal pages Using Debian Etch 4.1 amd64, Postfix 2.3.8, Dovecot v1.0.rc15 , have tried also 32bit version with same result Everything works great except when i send mail to non-existing user in existing domain Dovecot is ignoring Postfix main.cf values delay_warning_time = 4h and unknown_local_recipient_reject_code = 550 And is sending error message ca every two hours for 4 days like : Out: 220 mailserver2.mydomain.tld ESMTP Postfix (Debian/GNU) In: EHLO mail.otherdomain.tld Out: 250- mailserver2.mydomain.tld Out: 250-PIPELINING Out: 250-SIZE 10240000 Out: 250-VRFY Out: 250-ETRN Out: 250-STARTTLS Out: 250-AUTH PLAIN Out: 250-AUTH=PLAIN Out: 250-ENHANCEDSTATUSCODES Out: 250-8BITMIME Out: 250 DSN In: STARTTLS Out: 220 2.0.0 Ready to start TLS In: EHLO mail.otherdomain.tld Out: 250- mailserver2.mydomain.tld Out: 250-PIPELINING Out: 250-SIZE 10240000 Out: 250-VRFY Out: 250-ETRN Out: 250-AUTH PLAIN Out: 250-AUTH=PLAIN Out: 250-ENHANCEDSTATUSCODES Out: 250-8BITMIME Out: 250 DSN In: MAIL From:<rh(a)tvujweb.cz> SIZE=704 Out: 250 2.1.0 Ok In: RCPT To:<non_existing_user(a)existingdomain.net> Out: 451 4.3.0 <non_existing_user(a)existingdomain.net>: Temporary lookup failure In: QUIT Out: 221 2.0.0 Bye I have googled out somewhere parameter for dovecot.conf unknown_address_reject_code = 550 , but Dovecot is not taking this one. Is Dovecot using Postfix paramteres delay_warning_time = and unknown_local_recipient_reject_code = ?? Assuming not, becauase Postfix is delivering over Dovecot, as defined in postfix/master.conf dovecot unix - n n - - pipe flags=DRhu user=vmail:mail argv=/usr/lib/dovecot/deliver -d $(recipient) So how can i set this two parameters ?? Thanks in advance for any hint Radim -- Radim Hejc

[Dovecot] documentation for developers
by Boris Lorbeer 20 Sep '07

20 Sep '07

Hi there, I have two questions: - Is there a dovecot documentation for developers (apart from the source itself)? - In the site I am concerned with, it happens very often that one mail is delivered to hundreds of recipients. Since almost all of the mailboxes are situated on the same filesystem, the mail is delivered by just saving it once and establishing hardlinks from the mail directories of all the other recipients to this one mail. My question now is: can dovecot's lda "deliver" be configured to deliver mail to more than one recipients and to use the hardlink method just described? Boris -- Dipl. Phys.

[Dovecot] 'r' flag in ACL stomping on 'l' flag effect
by Phil Edwards 19 Sep '07

19 Sep '07

We're using Dovecot 1.0.3, and I'm setting up some shared IMAP folders. The eventual goal is to do the standard "learn as spam" / "learn as ham" type of setup, with some cron jobs to do the message extractions. But there's one minor twist: the "learn as ham" folder will need to be write-only for users. (I'll either create a fake user with read access to extract the mail for sa-learn, or do some local filesystem access, etc. A problem for a future day.) The issue is that some of the mail being misclassified might contain sensitive information. So users should be able to copy messages into that folder, but not list or read other messages. (Yes, they will be removed from the folder by the future sa-learn script, don't worry.) I can get normal operation with the ACL plugin and a global ACL file: # "TestTwo" mailbox acl file: authenticated lrwik * OK Dovecot ready. 1 login ........ 1 OK Logged in. 2 list "" * * LIST (\Noselect \HasChildren) "." "Testing/" * LIST (\HasNoChildren) "." "Testing/TestTwo" * LIST (\HasNoChildren) "." "Testing/TestOne" 2 OK List completed. 3 select "Testing/TestTwo" * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 0 EXISTS * 0 RECENT * OK [UIDVALIDITY 1189458953] UIDs valid * OK [UIDNEXT 1] Predicted next UID 3 OK [READ-WRITE] Select completed. Now, I change the TestTwo acl file to read authenticated lwik but can no longer subscribe to the folder: 1 login ........ 1 OK Logged in. 2 list "" * * LIST (\Noselect \HasChildren) "." "Testing/" * LIST (\HasNoChildren) "." "Testing/TestTwo" * LIST (\HasNoChildren) "." "Testing/TestOne" 2 OK List completed. 3 subscribe "Testing/TestTwo" 3 NO Permission denied According to http://wiki.dovecot.org/ACL, the 'l' flag means "Mailbox is visible in mailbox list. Mailbox can be subscribed to." but the second part of that statement is not actually happening. Is this a misunderstanding on my part, or a bug? -- Phil Edwards

[Dovecot] Delete mails in dovecot POP3 has a bug/feature
by Nuilte Infotech 19 Sep '07

19 Sep '07

When a mailbox has abt 40 mails with 4-5 mb attachments , it is quite common for the pop3 connection to get timed out or disconnected esp. if user has dialup modem. In this case , dovecot seems to REALLY HIT the user hard. Because it simply DOES NOT delete mails , even if user requested so. It only deletes the mails if users succesfully logs out. No other pop3 server has this problem so i would request this bugs is fixed ASAP. Effect of this bug - user has to retry multiple times and download multiple copies of mail before it finally deleted. Server Using ubuntu 7.04 Feisty Fawn + standard apt-get dovecot. Client end tested using getmail+BrokenUIDLPOP3Retriever To be Fixed - dovecot should delete mail even if the client connection gets "broken" or disconnects "ungracefully". e.g. user hits CTRL+C with getmail.

[Dovecot] What's the best way to authenticate against Active Directory?
by Chris Johnson 19 Sep '07

19 Sep '07

Hi all, I'm working on a replacement for a legacy linux mail server: courier POP/IMAP, Postfix, OpenLDAP. One of the requirements of the new mail server is to authenticate against our AD infrastructure (I'll still keep a userdb in OpenLDAP). SSO is not required since most of the clients don't log into our domain. The current system has about 1,000 concurrent users on it during the day (almost all are IMAP users). Inbox size varies but is generally very high 1GB+. I'm considering dovecot as a replacement for courier IMAP on the new server mainly for performance reasons. Cyrus was also considered but I'd rather work with maildir format inboxes. I'm in the process of installing a "proof of concept" server with CentOS 5 and dovecot-1.0-1.2.rc15.el5. the production system will most likely run on RHEL Question: What's the best way (most reliable/fastest) to authenticate dovecot to AD? If someone is doing this in a production environment can you offer any hints on configuration for performance or what to expect in general? Thanks, chrisj

[Dovecot] Dovecot 1.0.3: mbox problems for newly created users
by Bernd Kuhls 18 Sep '07

18 Sep '07

Hi, I am having problems with Dovecot 1.0.3 and Thunderbird 2.0.0.6 when using a new user account without any mbox files present. Directory /home/$user/.imap_mail/ does not exist when Thunderbird first tries to login using IMAP to the account. On login this directory is created with a zero byte Trash file and .subscriptions containing string "Trash", so far, so good. Now I create a new message in Thunderbird and save it as draft. A zero byte file "Drafts" is created in /home/$user/.imap_mail/ but the message I wanted to save got _lost_, /home/$user/.imap_mail/Drafts stays at zero bytes. The next message I try to save as draft finds its way to the Drafts mbox however. Please note that no /home/$user/.imap_mail/inbox has been created although a inbox is shown in Thunderbird. When I move the saved message from Drafts to the inbox folder shown in Thunderbird, it gets saved in /var/mail/$user instead of /home/$user/.imap_mail/inbox, I guess this is due to the use of the mbox_snarf plugin, right? /home/$user/.imap_mail/inbox is the maildrop for Exim, which handles incoming mails, but in this scenario the user did not receive any emails yet. If I manually create /home/$user/.imap_mail/inbox, then moving a message from Drafts to the Thunderbird-displayed inbox works. How to fix this problem? Especially messages getting lost is really bad because I am in the process of changing our mail server setup from Exim/UW-Imapd to Exim/Dovecot, where I have to move 100+ /var/mail/$user mbox files to /home/$user/.imap_mail/inbox. But when Dovecot can not properly save files to previous non-existing mbox files, like Drafts, this is really a problem.

[Dovecot] IP based virtual users: stripping login domain?
by Alan Ferrency 17 Sep '07

17 Sep '07

Hello. I have a likely unusual request regarding IP based virtual dovecot users. When you specify a passdb passwd-file name containing "%d", then the domain portion is stripped from the login username, before the user is checked in the passwd-file. However, if you specify a passwd-file name containing "%l" (the local IP), the domain portion of the login is not stripped off before the username is checked in the passwd-file. This behavior makes sense, and should be considered the right and proper thing to do. But in this case, I want to do something different anyway. In the setup I'm working on, most logins will use domain based virtual usernames. However, if a customer logs in with an unknown domain in their login username, I'd like to fall back to IP-based virtualization, based on the local IP they connect to. I can't use auth_username_format to strip off %d, because that would break the domain based virtualization. What I need is an option to make %l work the way %d already works; or a format inside a passwd-file which allows for partial matches in the "username" column. If I can do this directly using a passwd-file, I'd like to do that. It seems like it'd be easy if I were using an SQL back end, but that's not an option. It's possible with an external authentication script, but I want to explore more direct configuration options, first. Does anyone have any recommendations? If what I want can't already be done, and I patched dovecot to do one of these things, how likely would it be to have that patch merged into the project? Thanks, Alan Ferrency pair Networks, Inc. alan(a)pair.com

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] 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

http://dovecot.org/releases/1.0/dovecot-1.0.5.tar.gz http://dovecot.org/releases/1.0/dovecot-1.0.5.tar.gz.sig v1.0.4 was a bit bad release. - deliver: v1.0.4 broke home directory handling - maildir: Creating mailboxes didn't use dovecot-shared's group for cur/new/tmp directories.

[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

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

[Dovecot] dirsize quota assertion problem
by Alan Ferrency 14 Sep '07

14 Sep '07

Our current virtual mailbox configuration is not compatible with one of the assertions in the dovecot quota plugin's assertions in quota-dirsize.c. I believe the assertion is incorrect, but I would also be happy if I could get the same result with a better configuration setting. Here is a sample passdb entry which causes the quota assertion to fail: test(a)example.com:<snip>:3007:1000::/usr/boxes/username/example.com::userdb_mail=mbox:~/test^/.imap:INBOX=~/test userdb_uid=3007 userdb_gid=1000 userdb_home=/usr/boxes/username/example.com userdb_quota=dirsize:storage=100 The imap folder is "~/test^/.imap" and the INBOX is "~/test". As you can see, these are in different locations, but the INBOX string happens to be a substring of the imap folder directory. An example of the failed assertion error: Aug 31 16:44:13 www2 dovecot: IMAP(test(a)example.com): file quota-dirsize.c: line 180 (quota_count_path_add): assertion failed: (!is_file) This particular error log line was generated by dovecot 1.0.3, but the code in quota-dirsize.c is the same in dovecot 1.1 alpha3's version of quota-dirsize.c: 131 if (strncmp(count_path[i].path, path, strlen(path)) == 0) { 132 /* the new path contains the existing path */ 133 i_assert(!is_file); 134 count_path += i; 135 break; 136 } First, quota_count_path_add() is called for directory "~/test^/.imap" and it succeeds. When it is subsequently called for file "~/test": - the strncmp matches because "~/test" is a substring of "~/test^/.imap" - the assertion fails because "~/test" is a file and not a directory It seems to me that instead of asserting !is_file, it would be better to simply skip the conditional in that case, since a path variable that is a file should never be tested to see whether it contains an existing path. if (!is_file && strncmp(count_path[i].path, path, strlen(path)) == 0) { /* the new path contains the existing path */ count_path += i; break; } But this also has a bug: if path is a directory which substring matches count_path[i].path, but the same path with a directory separator appended to it does not substring match count_path[i].path, then it is a different path and does not contain the existing path. For example, if count_path[i] is the directory /usr/home/test/mailbox_folders, and path is the directory /usr/home/test/mailbox, then /usr/home/test/mailbox does not contain/usr/home/test/mailbox_folders, and this condition should fail. If some other code were to enforce that /usr/home/test/mailbox be terminated with a directory separator, then this is not a problem and my patch should work. I hope this makes sense.

[Dovecot] Dovecot + virtual users
by bichumo 13 Sep '07

13 Sep '07

Hi, I'm running FreeBSD, Dovecot, Postfix (virtual users), MySQL, Squirrelmail. I have installed squirrelmail-quota_usage-plugin, but I cannot make it work. It mentions "If you have an IMAP server with QUOTA Extension capability...". In dovecot.conf I have enabled "mail_plugins = quota" near protocol pop3 and protocol lda, near protocol imap I have "mail_plugins = quota imap_quota". Near " plugin { ..." I have "quota = maildir:storage=204800". I think that the problem of why I don't see quota in Squirrelmail is in file dovecot-sql near user_query. I have my users mailboxes in such format: /usr/local/virtual/domain.tld/username and my user_query looks like this: user_query = SELECT maildir, 125 AS uid, 125 AS gid, concat('maildir:storage=', quota) AS quota FROM mailbox WHERE username = '%u' AND active = '1', I think that in my user_query I'm missing something. I do not get any errors in the dovecot and dovecot-debug logs, everything works fine, but I still can't see quota.

[Dovecot] Datehandling bug?
by Ed W 12 Sep '07

12 Sep '07

Hi, I am testing dovecot 1.0.3 alongside my existing courier installation and a number of my emails are heading to the top of the inbox even though they are rather old. Closer inspection shows that my mailclient (Thunderbird on Win32) is showing me some screwey dates for a number of messages. One example is an email which says: Date: 2007-08-21 11:42:43 But in TB I see the date shown as only: 03:27 ie just a time and no date OK, the date above is clearly not an RFC date, but any idea why this is showing up only under Dovecot? Is it a dovecot date handling issue? Cheers Ed W

[Dovecot] Deliver parameter problem
by Umut Arus 11 Sep '07

11 Sep '07

Hello, I'm using dovecot-1.0.5 with postfix. I have to use deliver from procmail because I have some filters. There is no document about how to using deliver parameters (-d) other than http://wiki.dovecot.org/LDA . If I set -d parameters manually as a username everything is ok. I can not set users' mail quota (don't lookup) with mysql db if I haven't set -d parameter as receipt username in procmail. How can I describe user (-d) parameter's variable in procmail?

[Dovecot] postfix + dspam + dovecot problem
by Lars Stavholm 11 Sep '07

11 Sep '07

Hi All, I'm new to dovecot (coming from cyrus) and have a bit of a problem setting up postfix + dspam + dovecot. 1. postfix + dovecot: works like a charm. Using "mailbox_command = /usr/lib/dovecot/deliver" in postfix main.cf 2. adding dspam to the equation: unable to deliver: net_connect(/usr/var/run/dovecot/auth-master) failed: No such file or directory Using "mailbox_transport = lmtp:unix:/var/tmp/dspam.sock" in postfix main.cf (instead of the above mailbox_command), and the corresponding setting in master.cf. In /etc/dspam.conf I'm using... TrustedDeliveryAgent "/usr/lib/dovecot/deliver" And here's the full error message: Sep 11 02:10:38 nwinnie postfix/pickup[18313]: 090F1C042: uid=0 from=<root> Sep 11 02:10:38 nwinnie postfix/cleanup[7010]: 090F1C042: message-id=<20070911001038.090F1C042(a)nwinnie.telcotec.se> Sep 11 02:10:38 nwinnie postfix/qmgr[18318]: 090F1C042: from=<root(a)nwinnie.telcotec.se>, size=431, nrcpt=1 (queue active) Sep 11 02:10:38 nwinnie deliver(stava(a)nwinnie.telcotec.se): net_connect(/usr/var/run/dovecot/auth-master) failed: No such file or directory Sep 11 02:10:38 nwinnie dspam[10379]: Delivery agent returned exit code 75: /usr/lib/dovecot/deliver -d stava(a)nwinnie.telcotec.se Sep 11 02:10:38 nwinnie postfix/lmtp[7018]: 090F1C042: to=<stava(a)nwinnie.telcotec.se>, orig_to=<stava>, relay=nwinnie.telcotec.se[/var/tmp/dspam.sock], delay=0.35, delays=0.32/0.01/0.01/0.01, dsn=4.3.0, status=deferred (host nwinnie.telcotec.se[/var/tmp/dspam.sock] said: 421 4.3.0 <stava(a)nwinnie.telcotec.se> Delivered (in reply to end of DATA command)) So, postfix hands the message to dspam, dspam does its thing, dspam tries to deliver and fails. What throws me is that the delivery works as expected in case 1) but not in case 2), despite the fact I'm using the same delivery agent, i.e. /usr/lib/dovecot/deliver. Why would dovecot go for some other authentication method in case 2)? BTW, we're using PAM on top of LDAP. Any ideas appreciated. Cheers /Lars

[Dovecot] Write-only mailboxes
by Steffen Kaiser 11 Sep '07

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, I've setup a mailbox for reporting SPAM by simply symlinking it into the Maildir of selected users. In order to preserve anonymity of the users I setup the mailbox as follows: drwxr-xr-t 5 root fb 4096 2007-09-05 16:18 ./ drwxr-xr-x 7 root root 4096 2007-09-05 16:16 ../ drwx-wx-wt 2 spamd fb 12288 2007-09-10 16:17 cur/ hence, with read permission for the spam bot only. When Thunderbird copies mails from the same mail account into the folder, it seems like it tries to select the mail box afterwards, then a "Internal error occured. Refer to server log for more information." because of permission denied. When one copies mail from yet another account into the SPAM box, no such message appears. I guess, Thunderbird does not try the refresh the message count. Well, is there a possiblity to setup a Write-Only mailbox, with Dovecot v1.0.3 with the ACL plugin? Is there a working setup for write-only mailboxes with the ACL plugin?

[Dovecot] multiple emails
by dhottinger＠harrisonburg.k12.va.us 10 Sep '07

10 Sep '07

I have a weird issue where several users are recieving the same email's multiple times. Each email has a different que id, but are exactly the same otherwise. I thought at first this was a new spam, but I have local users doing the same thing. Im not sure where to start looking for the root of this problem. Seems to be pretty widespread across multiple platforms. I currently utilize openldap for user database, sendmail, Dovecot-Imap, and horde webmail. Im not sure where to start digging for this problem, Ive scanned through all my log files and havent found anything. Any guidance would be great. thanks, ddh -- Dwayne Hottinger Network Administrator Harrisonburg City Public Schools

Hello, I'm using dovecot-1.0.5 with postfix. There is no document about how to using deliver parameters (-d). I can not set mail quota with mysql db if I haven't set this parameter. How can I describe user (-d) parameter to procmail. Procmail set, :0 | /usr/local/dovecot/libexec/dovecot/deliver -f blabla -d blabla regards,

[Dovecot] Courier Migration
by Ed W 09 Sep '07

09 Sep '07

Hi Is it legal/sensible to use the following in the conf file # default namespace namespace private { separator = / prefix = inbox = yes } # for backwards compatibility: namespace private { separator = . prefix = INBOX. inbox = yes hidden = yes } The goal would be to migrate away from an Courier server, whilst still supporting clients using their old settings, but going forward they can use the new settings? In particular I always noticed that OE would not set the namespace automatically, so being able to leave it blank would be an advantage (fewer config issues for customers) Grateful if someone could confirm this works ok? Compatibility issues with Thunderbird/OE/Outlook 2003+ in particular? Cheers Ed W

Hi, We are using dovecot version 1.0.3. We have dovecot-ldap configured to authenticate users using ldap database. We are facing the inactivity problem with dovecot. After some hrs of successful working, dovecot logs shows the connection inactive problem with pop3 & imap server, & it starts rejecting the connection requests from clients. The problem goes away once we restart dovecot. The problem occurs again & again after some random time. Please help us in solving this problem.

[Dovecot] shared mailbox subfolder permissions
by David Leuschner 09 Sep '07

09 Sep '07

Hi all, when I create a subfolder in a public mailbox the dovecot-shared file is copied for the newly created subfolder and all mails get the owner, group and permissions from the file. Unfortunately the cur, new and tmp folders only get the permissions from the file but owner and group are set according to the creator. This effectivly makes the folder private to the creator. Is this the intended behavior? Is it a bug that has already been fixed in a later version? I am using 1.0.rc29. An example follows. Thanks for your help! David As an example .foobar was created manually (maildirmake) and permissions were setup using the shell: uml public # ls -al . .foobar .: total 24 drwxrwx--- 6 root pub 4096 Aug 18 13:05 . drwxrwxr-x 3 root mail 4096 Aug 18 11:10 .. drwxrwx--- 5 root pub 4096 Aug 18 11:42 .foobar drwxrwx--- 2 root pub 4096 Aug 18 10:50 cur -rw-rw---- 1 root pub 0 Aug 18 11:40 dovecot-shared drwxrwx--- 2 root pub 4096 Aug 18 10:50 new drwxrwx--- 2 root pub 4096 Aug 18 10:50 tmp .foobar: total 20 drwxrwx--- 5 root pub 4096 Aug 18 11:42 . drwxrwx--- 6 root pub 4096 Aug 18 13:05 .. drwxrwx--- 2 root pub 4096 Aug 18 11:42 cur drwxrwx--- 2 root pub 4096 Aug 18 11:42 new drwxrwx--- 2 root pub 4096 Aug 18 11:42 tmp After creating a subfolder 'baz' with Thunderbird the group of .baz is the group from dovecot-shared but the contained new/cur/tmp directories have the users primary group (instead of pub). uml public # ls -al . .baz .: total 28 drwxrwx--- 7 root pub 4096 Aug 18 13:09 . drwxrwxr-x 3 root mail 4096 Aug 18 11:10 .. drwxrwx--- 5 dleuschner pub 4096 Aug 18 13:09 .baz drwxrwx--- 5 root pub 4096 Aug 18 11:42 .foobar drwxrwx--- 2 root pub 4096 Aug 18 10:50 cur -rw-rw---- 1 root pub 0 Aug 18 11:40 dovecot-shared drwxrwx--- 2 root pub 4096 Aug 18 10:50 new drwxrwx--- 2 root pub 4096 Aug 18 10:50 tmp .baz: total 20 drwxrwx--- 5 dleuschner pub 4096 Aug 18 13:09 . drwxrwx--- 7 root pub 4096 Aug 18 13:09 .. drwxrwx--- 2 dleuschner dleuschner 4096 Aug 18 13:09 cur -rw-rw---- 1 dleuschner pub 0 Aug 18 13:09 dovecot-shared drwxrwx--- 2 dleuschner dleuschner 4096 Aug 18 13:09 new drwxrwx--- 2 dleuschner dleuschner 4096 Aug 18 13:09 tmp Here's my configuration: listen: localhost ssl_listen: * ssl_ca_file: /root/ca/ca.crt ssl_cert_file: /root/ca/crt/uml.crt ssl_key_file: /root/ca/keys/uml.key ssl_verify_client_cert: yes verbose_ssl: yes login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login namespace: type: private separator: . prefix: Priv. location: maildir:~/.maildir:CONTROL=~/.maildir/ctrl/priv:INDEX=~/.maildir/idx/priv inbox: yes namespace: type: public separator: . prefix: Pub. location: maildir:/var/mail/public:CONTROL=~/.maildir/ctrl/pub:INDEX=~/.maildir/idx/pub auth default: passdb: driver: pam args: * userdb: driver: passwd socket: type: listen client: path: /var/run/dovecot/auth-client mode: 432 master: -- David Leuschner Meisenweg 7 79211 Denzlingen Tel. 07666/912466

[Dovecot] SSL connections frozen on Dovecot 1.0.0
by Thibault VINCENT 09 Sep '07

09 Sep '07

Hello, We are running Dovecot 1.0.0 (Debian Etch, Backports.org, OpenSSL) in a production environment and we experience sporadic SSL connection problems. At the moment, it's difficult to tell if the server goes back to normal operation after some time or if it can be reproduces at any time because we have to restart it as soon as we get Nagios alerts. Some tests with openssl s_client have shown difficulties to proceed the SSL handshake (hanging at different stages), or no response to IMAP commands. SSL client used: openssl s_client -host imap -port 993 - First case : s_client hangs on the first output "CONNECTED(00000003)" and there is no handshake at all; - Second case : like the first but the handshake starts after a few minutes; - Third case : the handshake goes fine but the "OK" server banner is never sent (no response to commands); - Fourth case : the greeting banner is received but dovecot will never answer. The configuration file is almost identical to the default and SSL certificate is not the autogenerated one. Log files do not show dying process. I've searched the ML archive for SSL issues but not found related bug. Does anyone use the Backport.org package of Dovecot ? Thank you :) -- Thibault VINCENT tibal(a)reloaded.fr thibault.vincent(a)reloaded.fr PGP Key : 0x4BA8A39B

[Dovecot] postfix + dovecot lda,
by Michael Moritz 09 Sep '07

I'm trying to replace procmail with deliver but I'm having problems with the group part of things. I keep getting: Aug 29 16:44:19 dingbat deliver(mimo): open(/var/mail/.temp.dingbat.3969.d1689935a308e0dd) failed: Permission denied Aug 29 16:44:19 dingbat deliver(mimo): file_lock_dotlock() failed with mbox file /var/mail/mimo: Permission denied My primary group is mimo and I think it's trying to use that. I changed it to mail and things work. But I do not want all my users to have a primary group mail. Is there a way I can force deliver to use group mail as group and ignore the per user gid? I tried chmod 6755 /usr/lib/dovecot/deliver but no change. This is on debian/etch, help appreciated.... mimo

Hi folks, My institute's mail server was upgraded to RHEL5 with dovecot 1.0-2.1rc5 recently. And it uses PAM authentication which points to LDAP server. Now from time to time it gets Error like dovecot: Aug 29 09:23:59 Error: auth(default): pam(joshua,192.168.177.52): pipe() failed: Too many open files and users can not login. My config is like dovecot -n # /etc/dovecot.conf base_dir: /var/run/dovecot/ log_path: /var/log/dovecot info_log_path: /var/log/dovecot listen: * 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 login_greeting: ASIAA Dovecot ready. login_processes_count: 4 mail_location: mbox:/asiaa/home/%u/:/asiaa/home/%u/mail/:INBOX=/var/mail/%u:INDEX=/asiaa/home/%u/mail/dovecot_indexes mail_debug: yes mail_full_filesystem_access: yes mail_drop_priv_before_exec: yes mail_executable(default): /etc/dovecot_postlogin_beforeimap.sh mail_executable(imap): /etc/dovecot_postlogin_beforeimap.sh mail_executable(pop3): /etc/dovecot_postlogin_beforepop3.sh mail_process_size: 512 mail_plugin_dir(default): /usr/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 pop3_uidl_format(default): %08Xu%08Xv pop3_uidl_format(imap): %08Xu%08Xv pop3_uidl_format(pop3): %08Xv%08Xu auth default: passdb: driver: pam userdb: driver: passwd Any suggestion or help is appreciated Cheers Joshua

It doesn't work with '+' delimited address+extension >(I reported it in this list, but had no replies). Actually I managed to fix this setting global_script_path = /usr/local/etc/sieve/Junk instead of sieve_global_dir = The emails marked as spam were moved to correct directory which is Junk, as listed in user's subscriptions file and not INBOX.Junk. I also correcred my sieve file to say: require ["fileinto"]; # Move spam to Junk folder if header :contains ["X-DSPAM-Result"] "Spam" { fileinto "Junk"; # Stop here so that we do not reply on spams stop; } But now I can see following logs for some of the accounts.

[Dovecot] Don't let deliver create index files
by Martin Strand 09 Sep '07

09 Sep '07

For various reasons I want to use deliver with Postfix and Courier-IMAP, and it seems to work fine except for one thing: deliver creates some dovecot.* index files that Courier never uses (and I assume deliver doesn't need them) Is there a way to prevent that? Thanks, Martin

[Dovecot] Using NID_x500UniqueIdentifier as ssl_username_from_cert
by S. Wefel 09 Sep '07

09 Sep '07

Hi, please have a look at the attached patch for dovecot-1.0.3 These patch modifies ssl_proxy_get_peer_name() to use the NID_x500UniqueIdentifier as username instead of NID_commonName. The reason is, that the Common Name doesn't have to be unique for the whole mailserver. Example; in germany a lot of people got the first name "Andreas" and the last name "Schulz". Therefore a lot of certificates exists with subjects like this: C=DE,O=ABC,CN=Andreas Schulz/emailAddress=andreas.schulz(a)abc.de C=DE,O=DEF,CN=Andreas Schulz/emailAddress=andreas.schulz(a)def.de ... dovecot couldn't distinguish between these users. So we decide to use certificates with an X509v3 extension NID_x500UniqueIdentifier which allows to extend the subject by an unique ID, e.g. the unix-uid or a database unique key. The new certificates may look like this: C=DE,O=ABC,CN=Andreas Schulz/emailAddress=andreas.schulz(a)abc.de/x500UniqueIdentifier=user1 C=DE,O=DEF,CN=Andreas Schulz/emailAddress=andreas.schulz(a)def.de/x500UniqueIdentifier=user2 With the attached patch the user is taken from this extension and e.g. with userdb=ldap you can use the filter string user_filter = (&(objectClass=posixAccount)(uid=%u)) A good solution to use booth, the common name and the UniqueIdentifier is to extend settings like ssl_username_from_cert = no | yes | cn | uid where "yes" is similar to "cn".

[Dovecot] Server Timed Out: Outlook Express
by Jackie Hunt 09 Sep '07

09 Sep '07

Hi all, We just started running Dovecot this fall here on campus v 1.0. I've started getting some trouble reports from users. An Outlook Express users reported seeing the "Server has not responded in 60 seconds" messages. Waiting longer doesn't help, he has to stop/start Outlook Express to get connected again. Also have a Thunderbird user who is seeing that type of behavior first thing in the morning after being logged in all night. He has to stop/restart Thunderbird. Also, have had some reports of "disconnected" showing up on the Outlook2007 status bar. I've looked at the Dovecot log, and don't see any errors. I do see lots of "Disconnected", "Disconnected in IDLE" and "Disconnected: Logged Out". These last two seem normal, if I just see "Disconnected" is that a flag that we're losing connections abnormally? I know version 1.0.3 is out. I've looked at the changes, and the only one I can see that might be related to what we are seeing is the IDLE commmand fix. Was hoping for some advice on whether upgrading might resolve these issue. Any insight would be greatly appreciated. Jackie --- Jackie Hunt ACNS Voice: (970) 663-3789 Colorado State University FAX: (970) 491-1958 Fort Collins, CO 80523 Email: jackie.hunt(a)colostate.edu

[Dovecot] LDA bouncing mails after upgrade -- again
by Milan Holzäpfel 09 Sep '07

09 Sep '07

Hi Timo, some time ago (2007-03-24 and following) I asked whether it was intended that Dovecot deliver bounces mails (by terminating with status 89) if the deliver version is older than the rest of the dovecot installation. You replied that it was a bug, and that it had been fixed in <URL:http://dovecot.org/list/dovecot-cvs/2007-March/008346.html>. When I upgraded from Dovecot 1.0.2 to 1.0.3 a few days ago, I found out that this problem probably still exists: | Aug 28 09:38:03 host.example.org deliver(user(a)example.org): Module is for different version 1.0.3: /usr/lib/dovecot/lda/lib10_quota_plugin.so | Aug 28 09:38:03 host.example.org postfix/pipe[18356]: <ID>: to=<user(a)example.org>, relay=dovecot, delay=0.4, delays=0.13/0.09/0/0.18, dsn=5.3.0, status=bounced (Command died with status 89: "/usr/libexec/dovecot/postfix-deliver/deliver") The error message I posted in march was: | Mar 22 20:29:20 host.example.org deliver(user(a)example.org): Module is for different version 1.0.rc27: /usr/lib/dovecot/lda/lib10_quota_plugin.so | Mar 22 20:29:20 host.example.org postfix/pipe[17344]: <ID>: to=<user(a)example.org>, relay=dovecot, delay=1.9, delays=1.5/0/0/0.35, dsn=5.3.0, status=bounced (Command died with status 89: "/usr/libexec/dovecot/postfix-deliver/deliver") I suppose you still want to fix it.

[Dovecot] processing Dovecot maildirs with shell scripts
by M. Fioretti 09 Sep '07

09 Sep '07

Hello, I have a postfix server which uses procmail as its delivery agent to deliver incoming messages to several maildirs. For several reasons, not really relevant here, I need to process/refilter/sort again the content of these mailboxes before delivering the messages to the _other_ maildirs which Dovecot sees and serves to local or remote imap users. Basically, I need to write some shell scripts that, from cron jobs, regularly do this: foreach file in some_incoming_mailbox/new/ do #process the file and/or set some variable according to its content delete the file or mv it to some_other_maildir/new/ where the actual action and value of some_other_maildir is set every time by the "process the file" part of the script. The part that I still miss is guidelines to do these things safely, that is without losing or corrupting messages or doing anything else that would confuse dovecot. For example, under which conditions it is sure to move or delete (the Unix way, with mv or rm) a message from mailbox1/new/ to mailbox2/new, when the latter is served via dovecot to remote users? What is advisable and most efficient? Use locks (how?), only work on file which are at least one minute old? Should I move the messages to tmp instead of new? What else? Tips or pointers about this are very welcome. Ciao, Marco

Hi, Whitbox Linux 3 (RHEL) Dovecot 1.0.rc29 Using NFS From time to time does all mail get re-downloaded to Thunderbird. I would believe this has something to do with an index problem. I upgraded to 1.0 a few months ago but that didn't work well so I installed version 1.0.rc29 which worked better but we still get this problem from time to time.

[Dovecot] passing quota to deliver via command line
by bill-dovecot＠carpenter.ORG 09 Sep '07

09 Sep '07

Is there any way to pass things like "quota=" for the quota plugin to the deliver LDA via the command line or as an environment variable or whatever? I've got all the info I need in my MTA to avoid a userdb lookup in the LDA, but I still have to do the userdb query to get the per-user quota number (the default quota works fine, of course). -- bill-dovecot(a)carpenter.ORG (WJCarpenter) PGP 0x91865119 38 95 1B 69 C9 C6 3D 25 73 46 32 04 69 D6 ED F3

[Dovecot] passdb/userdb args
by Daniel L. Miller 09 Sep '07

09 Sep '07

I'm a bit unclear on these - give me a moment to ramble on. I should mention I'm using version 1.0.3, my primary backend is LDAP, and I do NOT want to store user mail folders in my LDAP directory. I currently have the following: default_mail_env = maildir:/var/mail/%d/%n passdb ldap { args = /etc/dovecot/dovecot-ldap.conf } # Instructions for deliver state a userdb is still required if using prefetch userdb ldap { args = /etc/dovecot/dovecot-ldap.conf } userdb prefetch { } My dovecot-ldap.conf is pretty simple - the trimmed version is: hosts = localhost auth_bind = no user_attrs = %d/%n=mail user_filter = (mail=%u) pass_attrs = (&(userPassword=password)(mail=%u)) user_global_uid = 5000 user_global_gid = 8 I recognize that the pass_attrs is incorrect for a prefetch config - but I couldn't get it to work. My mail folder structure is /var/mail/domain/username. If, under 1.0.3, I can't use the %d/%n variables to build the user/home/mail parameters in the LDAP config, can I do it in the configuration stanza? Something like: passdb ldap{ args = home=%dn/%n mail=%d/%n /etc/dovecot/dovecot.conf } -- Daniel

I have a user that gets client timeout errors when he tries to delete/clean up his massive "Spam" folder (many thousands of mail messages). He uses Thunderbird and has it configured to use "Move to Trash" when he deletes messages. I find the following in Dovecot's log file when it happens: Aug 28 10:38:22 ifm.liu.se dovecot: [ID 107833 mail.error] IMAP(bpn): Timeout while waiting for lock for transaction log file /home/bpn/Maildir/.Trash/dovecot.index.log Aug 28 10:38:24 ifm.liu.se dovecot: [ID 107833 mail.info] IMAP(bpn): Disconnected Any suggestions on what I can tuned/fix in Dovecot to solve this issue?

[Dovecot] trouble with deliver in 1.0.4
by Jack Bailey 09 Sep '07

09 Sep '07

Ok, here's one for the idiot file. I just installed dovecot-1.0.4 on my personal system for testing, a system which has to be the simplest dovecot configuration possible. deliver is barking about something with which version 1.0.3 has no problem. I looked over the wiki, googled, and see nothing wrong. The error: deliver(jjb): Sep 07 21:39:40 Fatal: Failed to create storage for 'jjb' with mail 'mbox:/HOME_DIRECTORY_USED_BUT_NOT_GIVEN_BY_USERDB/:INBOX=/var/mail/jjb' In dovecot.conf: userdb passwd { # [blocking=yes] - By default the lookups are done in the main dovecot-auth # process. This setting causes the lookups to be done in auth worker # processes. Useful with remote NSS lookups that may block. # NOTE: Be sure to use this setting with nss_ldap or users might get # logged in as each others! #args = args = blocking=yes } and mail_location = mbox:~/:INBOX=/var/mail/%u Clues generously accepted, Jack

[Dovecot] Two newbie problems
by Timothy Murphy 08 Sep '07

08 Sep '07

I've started running dovecot on my server under Fedora 7, to act as an IMAPS server for kmail. 1. I see my email fine on my laptop in an IMAPS account, but it doesn't get updated - I mean I don't get any new email - until I run kmail on my server. This isn't a great problem, as I am always logged to the server with ssh, and I just start kmail and stop it after a few minutes. Then I run kmail on my laptop, and the new mail is there. But I assume this is not the intended system? 2. I opted (probably mistakenly) to set ~/Mail/inbox/ as my base IMAPS directory on my server. I'd like to change this to ~/Maildir (I use maildir folders). Is it relatively easy to do this? I tried copying my email to ~/Maildir/ and changing the setting in /etc/dovecot.conf (and restarting dovecot), but for some reason I could not see the email on my laptop. Any advice or suggestions gratefully received.

[Dovecot] o/s tuning for imap
by Ken A 07 Sep '07

07 Sep '07

I'm switching from a pop3 only dovecot install to a pop3/imap install and I'm wondering how many connections every 100 'normal' imap users might have/keep open? I'm wondering if I need to tweak any o/s related things, like time_wait, etc. Any pointers would be greatly appreciated. Thanks, Ken A.

Also taken from WIKI http://wiki.dovecot.org/VirtualUsers You can create for example one vmail user which owns all the mails, or you can assign a separate UID for each user. See UserIds#mailusers for more information about different ways to allocate UIDs for users. All I want is to be able to access the mail, with the same my "virtual_uid_maps = static:501"(set in my postfix main.cf) All of these say it can be done, but how do I do it?

[Dovecot] Quota bug in deliver?
by FORMER 03 | Baltasar Cevc 06 Sep '07

06 Sep '07

Hi, I may be wrong, but I suspect a bug in dovecot deliver when using quotas. I've put some mails into a mailbox and then reduced the quota, to have the mailbox be over quota - here's the quota informaiton: [...] 2 getquotaroot INBOX * QUOTAROOT "INBOX" "" * QUOTA "" (STORAGE 880 5) 2 OK Getquotaroot completed. [...] When I have a setup with quotas only in the database, everything works as expected and deliver denies the message: Sep 5 21:50:14 ms4 deliver(postfach(a)email5.former03.local): msgid=<20070905195014.9D874239C007(a)ms4.srv.hoster03.de>: save failed to INBOX: Quota exceed ed Sep 5 21:50:14 ms4 deliver(postfach(a)email5.former03.local): msgid=<20070905195014.9D874239C007(a)ms4.srv.hoster03.de>: Rejected: Quota exceeded When I put a standard quota into the config as follows, the delivery succeeds (apparently deliver checks the standard quota, while IMAP correctly checks the quota from the database if it is returned.

[Dovecot] securing dovecot proxy connections
by bill-dovecot＠carpenter.ORG 06 Sep '07

06 Sep '07

The wiki <http://wiki.dovecot.org/PasswordDatabase/ExtraFields/Proxy> page says this: "The connections created to the destination server can't be TLS/SSL encrypted.". Hrmm. Right now, with perdition, I'm forcing the use of STARTTLS on the internal connections. I'd just as soon get rid of perdition (to have one less moving part in my architecture), but I need the secure connections. Is there a way to configure dovecot's internal proxy connections to use STARTTLS or some other SSL/TLS level of security? (Without a bunch more research, I don't know what the interaction is between the real client, the dovecot proxy, and the destination server.) -- bill-dovecot(a)carpenter.ORG (WJCarpenter) PGP 0x91865119 38 95 1B 69 C9 C6 3D 25 73 46 32 04 69 D6 ED F3

[Dovecot] How do I use sieve to move bounces?
by Jef Driesen 06 Sep '07

06 Sep '07

How can I use sieve to move bounces and non delivery reports (i.e. anything with an empty envelope from) to a special mailbox? I placed this snippet at the start of my sieve script require ["envelope", "fileinto"]; if envelope :is "from" "" { fileinto "INBOX.Reports"; stop; } But mails are not moved to the reports mailbox, and they are still processed by the rest of the script.

[Dovecot] OT Project idea: IMAP plugin for Google Desktop
by Kenneth Porter 06 Sep '07

06 Sep '07

Posting here, as Dovecot seems to be the premier IMAP server available. In case anyone is looking for something to work on, I found today that Google Desktop only understands email clients that keep mail on the client, and it would be nice if there was a plugin that understood IMAP. Here's a site that seems to explain how to write such plugins: <http://www.plugindevelopment.com/>

[Dovecot] alert function (possible WIBNI)
by Stewart Dean 05 Sep '07

05 Sep '07

The imapd spec has a provision for an alert pop-up of any ASCII text message contained in /etc/imapd.alert on the IMAP server. Can I assume this is implemented on DC? It'd be real nice if in addition to the current all-users message, it was possible to do a per-user alert...but I guess that would be something for IMAP standards....... -- ==== Stewart Dean, Unix System Admin, Henderson Computer Resources Center of Bard College, Annandale-on-Hudson, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035

[Dovecot] Dovecot + Sieve
by Marcin M. Jessa 04 Sep '07

04 Sep '07

Hi guys. I installed dovecot 1.0.3 with sieve plugin. It looks like sieve is loaded fine by dovecot [1]. I set up dovecot to use sieve globally: protocol lda { mail_plugins = cmusieve quota sieve_global_dir = /usr/local/etc/sieve/Junk ..... } And created a sieve file which is supposed to move all the Spam marked by dspam to users's Junk folder (listed as Junk in the subscriptions file) : require ["fileinto"]; # Move spam to Junk folder if header :contains ["X-DSPAM-Result:"] "Spam" { fileinto "Junk"; # Stop here so that we do not reply on spams stop; } I also set up postfix to use pipe mail through dovecot: mailbox_command = /usr/local/libexec/dovecot/deliver The problem is dovecot seems to be ignoring my sieve rule and delivers emails directly to INBOX. Any idea how to fix that?

[Dovecot] rule of thumb for indexing overhead
by bill-dovecot＠carpenter.ORG 30 Aug '07

30 Aug '07

I realize it's hard to be precise about this, but does anyone have a feel or rule of thumb for a couple of aspects of indexing overhead? 1. Proportionally, how much space does it take for all 4 files? If I want to give my users a quota of 100 MB for messages, how much real space should I plan for so that I won't run out of space for indexing? 2. What's the overhead in rebuilding index files? Suppose I use an LDA other than dovecot, so at least the INBOX index is frequently getting out of date. Does it cost much (in CPU, memory, and disk IO) to rebuild the index files? (I'm using maildir.)
