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

24 Sep '07

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

The client connection is simply closed. I am not getting a core dump for this; I am not sure whether I am supposed to. I configured Dovecot according to the instructions at http://www.dovecot.org/bugreport.html and core dumps generally work on my system, eg.

[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] Is anyone using the dspam plugin for dovecot 1.1?

I'm about to try to adjust the dspam plugin code to dovecot-1.1, but before starting out on this, I thought I'd ask the list: anyone done it already? /L

[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

[Dovecot] Binary packagers: BSD license issues

Adding this SHA256 code made me read the BSD license once again. It says: * 2. Redistributions in binary form must reproduce the above copyright * notice, this list of conditions and the following disclaimer in the * documentation and/or other materials provided with the distribution. Then there are a few files from Cyrus as well which contain: * 4.

I think I'd really like to get rid of those base64.c and utc-mktime.c exceptions.. There's probably also an easier/faster way to implement utc_mktime(). Anyway.. 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. So I think I should add these to COPYING file somehow. Any suggestions?

[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.

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
by Jasper Bryant-Greene 22 Sep '07

22 Sep '07

Deliver from latest 1.1 HG with sieve also from latest 1.1 HG is dying with an assertion failure when it delivers to my mailbox. Other mailboxes on the same system are unaffected, but I can read my mailbox fine through IMAP. Dovecot and sieve were compiled with -march=nocona -pipe -ggdb I've commented out my entire sieve script and the problem still occurs. file index-mail-headers.c: line 590 (index_mail_get_raw_headers): assertion failed: (ret != -1) - Last output repeated twice - Raw backtrace: /usr/libexec/dovecot/deliver(i_syslog_panic_handler+0x2b) [0x493125] -> /usr/libexec/dovecot/deliver(i_fatal+0) [0x492b17] -> /usr/libexec/dovecot/deliver [0x44f7cf] -> /usr/libexec/dovecot/deliver(index_mail_get_first_header+0x30) [0x44fb9b] -> /usr/libexec/dovecot/deliver(mail_get_first_header+0x3a) [0x47ca3d] -> /usr/libexec/dovecot/deliver(deliver_get_return_address+0x21) [0x41453b] -> /usr/lib/dovecot/lda/lib90_cmusieve_plugin.so(cmu_sieve_run+0x14b) [0x2b3687f194a1] -> /usr/lib/dovecot/lda/lib90_cmusieve_plugin.so [0x2b3687f169ba] -> /usr/libexec/dovecot/deliver(main+0x8dc) [0x415c4d] -> /lib/libc.so.6(__libc_start_main+0xe3) [0x2b3687cf6533] -> /usr/libexec/dovecot/deliver [0x4137a9] Jasper

[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.

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

[Dovecot] v1.1 alpha6: Log synchronization error ... Append with UID 0

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

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 ??

[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.)

[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

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

[Dovecot] v1.1.alpha6 released

17 Sep '07

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