[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.

[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.

[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

[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
