[Dovecot] gnus/dovecot open transactions panic
by Greg Troxel 24 Nov '10

24 Nov '10

I have been using dovecot with gnus for a long time. Recently, I started getting failures, and I think it's a dovecot problem triggered by gnus being more aggressive, but I'd like to hear opinions about whether I should pursue this as a gnus bug. The log shows: Oct 25 19:27:36 gdtserver dovecot: IMAP(gdt): Panic: Trying to close mailbox foo.bar with open transactions Oct 25 19:27:36 gdtserver dovecot: dovecot: child 26231 (imap) killed with signal 6 (core not dumped - set mail_drop_priv_before_exec=yes) and this seems to be triggered when dovecot is going GCC: to a local mailbox (not imap) when sending, but also semi-randomly. most of dovecot -n: (I'm sure that I'm not having auth problems and would rather not post that part): # 1.2.14: /usr/pkg/etc/dovecot.conf # OS: NetBSD 5.1_RC1 i386 protocols: imaps login_dir: /var/run/dovecot/login login_executable: /usr/pkg/libexec/dovecot/imap-login login_processes_count: 4 login_max_processes_count: 16 max_mail_processes: 32 first_valid_uid: 128 mail_location: maildir:~/IMAP I have 162 mailboxes polled by gnus on this dovecot instance. I get the panic on various mailboxes and I can't see a pattern. I do get Checking new news... nnimap-send-command: SIGPIPE raised on process *nnimap*; closed it From gnus. I then look at the listed one in the panic, and *imap-log* From gnus. This just may be an artifact of pipelining, but the panic-list mbox has 30 more after it that were sent, as in: 19:35:43 506 EXAMINE "mbox.named-in-panic" (QRESYNC (1208908407 1)) [30 more lines] I'm guessing that this is a dovecot problem. I realize I should update to 1.2.15 :-) but I didn't see anything in the 1.2.15 release notes that looks like a match.

Tks timo, my plugin is under imap and pop protocol, i will put it in global conf. The syntax for doveadm in socket, is the same as the doveadm app? Ex. Doveadm expurge -u user mailbox inbox savedbefore 3w Than i create a connection to unix socket and write in socket the "expunge -u user mailbox inbox savedbefore 3w" I made a small socket program, doing this but it doesnt work...

[Dovecot] LDAP Filter
by Joy 23 Nov '10

23 Nov '10

Dear All, All my users reside in ldap and i am using filter to restrict access to imap and pop service which is working good but as my webmail also uses the imap service, restricting imap will also cause my users to login to webmail. I am looking for a way to bypass the same for a particular ip or loop back ip. Hoping to get answer ... Thanks Regards Piyush Joshi

[Dovecot] Doveoct crashes: UID
by Peer Heinlein 23 Nov '10

23 Nov '10

We're running Dovecot 2.0.2 and sometimes a user creates several imap- prozesses, all of them hanging with the UID-command, using 100% of the CPU resources: root@mail:~# ps ax | grep UID 8005 ? R 266:52 dovecot/imap [user(a)example.com 192.168.5.5 UID] 10342 ? R 250:33 dovecot/imap [user(a)example.com 192.168.5.5 UID] 10539 ?

R 243:55 dovecot/imap [user(a)example.com 192.168.5.5 UID] This situation is triggered by two users only. Looks like their mailclient is sending a special command, that triggers the crash. Is it a bug or another problem? Is this a bug already fixed in Dovecot 2.0.3? - Fixed an infinite loop introduced by v2.0.2's message parser changes. Unfortunetaly I can't try an update at the moment. :-( Peer -- Heinlein Professional Linux Support GmbH Linux: Akademie - Support - Hosting http://www.heinlein-support.de Tel: 030 / 40 50 51 - 0 Fax: 030 / 40 50 51 - 19 Zwangsangaben lt. §35a GmbHG: HRB 93818 B / Amtsgericht Berlin-Charlottenburg, Geschäftsführer: Peer Heinlein -- Sitz: Berlin

[Dovecot] Namespace help
by Joy 23 Nov '10

23 Nov '10

Dear All, I am currently using courier-imap which uses INBOX. namespace configuration now i am willing to use dovecot instead of courier-imap but without INBOX. namespace configuration means default namespace of dovecot which helps me to sort out no of mail client issues as well. I know that i can change the default namespace configuation of dovecot to work with courier-imap namespace but not willing to do that so suggest me something which can help me doing the same. Is it possible using postlogin script or something else ? Thanks Regards Piyush Joshi

[Dovecot] multiple IMAP ports, each announcing different capabilities

[Dovecot] "list" ACL privilege ignored for LSUB command?
by Willie Gillespie 22 Nov '10

22 Nov '10

Hello, I am new to this list, so feel free to correct me if I do something wrong. I don't have a problem, just a question. The RFC which covers IMAP ACLs [1] states that one of the standard rights is: l - lookup (mailbox is visible to LIST/LSUB commands, SUBSCRIBE mailbox) If I have a shared or public namespace and have a mailbox for which I do not have lookup rights, Dovecot seems to do great with the LIST commands at not showing it to me. Two things I noticed though: SUBSCRIBE-ing to the mailbox is still successful LSUB will list mailboxes which I do not have lookup rights to I imagine the first issue is easy enough to correct since it's just another check before actually subscribing. The second issue seems a little more difficult in my mind since Dovecot seems to just dump the subscription files to the client without checking whether the mailbox is allowed or not. I imagine a similar issue popped up with the LIST command and that's why the dovecot-acl-list files exist. Anyway, am I right in my observations, or am I completely overlooking something obvious? Thanks! Willie [1] http://tools.ietf.org/html/rfc4314#section-2.1 Dovecot's wiki also indicates support for this in http://wiki1.dovecot.org/ACL#ACL_files I'm using version 1.2.9 with the acl and imap_acl mail_plugins in case that matters.

[Dovecot] Soft Quota for moving messages
by Tim Traver 22 Nov '10

22 Nov '10

Hi all, ok, I have an account that is over quota, but they are unable to move things to the trash, because the system is giving an error because of course it is over quota. Is there a quota setting that will let them move things to the trash without error? this of course would be so they could decrease their disk usage and become under quota again... Thanks, Tim.

[Dovecot] What is that error all about: "Timeout leak: 0x4bd230"
by Christian Rohmann 22 Nov '10

22 Nov '10

Hey dovecot-users, we are running dovecot 1.2.15 and are seeing some odd errors in our logfiles: --- dovecot.log --- 2010-11-22 12:34:56 imapserver local2.warning dovecot dovecot: IMAP(username(a)domain.tld): Timeout leak: 0x4bd230 --- /dovecot.log --- Those errors only appear if connections are done using IMAP (via Horde's IMP Webmail). With POP3 we don't see any of those errors. We actually don't see anything in general being broken or wrong (no errors on the webmail machines, no user complaints), but these errors are constantly being logged. Where would one start to look for the cause? Thanks for your help, Regards Christian

[Dovecot] Confused about Maildir
by Glen Lee Edwards 22 Nov '10

22 Nov '10

I'm trying to configure Dovecot 2.0.7. In the Dovecot Wiki for Maildirs it says that Maildirs are almost always located in ~/Maildir. I'm a Linux end user, not a programmer, so I may be wrong in this; but isn't the notation "~/" used for system users only to reference their home page; /home/<user>? If that's the case, then does that mean that Maildirs can only be used with system users and not with vmail accounts? Glen

[Dovecot] dsync mbox->mdbox II: highest_modseq changed
by Axel Thimm 19 Nov '10

19 Nov '10

Hi again, after replacing CRLF in 4 mboxes dsync was able to sync all of the 30+GB mailstore to mdbox. Now the (repeated) calling of dsync yields info messages of the kind dsync(athimm): Info: old/speicher: highest_modseq changed: 1 != 10 dsync(athimm): Info: root/root-heretic: highest_modseq changed: 1 != 10 dsync(athimm): Info: lists/ccrma.stanford.edu/planetccrma: highest_modseq changed: 11 != 14 I actually have 987 such messages for a total of 1115 mboxes. I checked a couple of them to see whether this is a CRLF issue and found no CRLF, so it's probably something different. As long as the mboxes were still being delivered to or read from I thought it was normal, but I'd like to see a silent dsync which would give me more confidence in the migration process. So I kept from delivering to the mbox store as well as reading from it and performed multiple dsyncs. The output of dsync became stable, e.g. the "highest_modseq changed" messages were exactly the same. Before nuking all indexes from the mbox storage and the mdbox itself and then repeating the whole process (which does take a long time), I wanted to know whether I should debug something. Thanks! -- http://thimm.gr/ - http://ATrpms.net/

[Dovecot] Dovecot and user's quota
by oriol llistes 18 Nov '10

18 Nov '10

Hi, We are planning to use Dovecot-2.0.5 (Maildir format) as IMAP server. Currently, we are using Postfix+UW-Imap (mbox format) with the following configuration: - Postfix: Sends new messages to /var/mail/user - UW-IMAP: Reads mails from /var/mail/user and moves them to ~/nsmail/mbox Using that configuration, when a user overtakes his HOME’s quota, the MTA is still able to send new messages to the user, although he cannot read it until he frees HOME space. Can we configure Dovecot to work in the same way? I mean… 1)Postfix must use /var/mail partition for new mails. 2)Dovecot must move these mails to user’s HOME. 3)User’s HOME must be in Maildir format. If that is not possible, how can we achieve an equivalent solution? Thanks in advance. Oriol.

[Dovecot] dovecot with Active Directory problem
by marie ot 18 Nov '10

18 Nov '10

Hello, I am using dovecot-2.0.6 with NetBSD amd64. Active Directory is used as an authentication server. (Windows Server 2008 R2) However, the message of "Operations error" was displayed first and it did not move. It solved it by understanding that this is because the authority of the user who used it for bind was insufficient, and adding to "Account Operators" group. # Though it is not the best. The error "Error: re_encode_request new request is" occurs, and it doesn't operate still as follows. Postfix operates though connects with LDAP. The following are samples. ------------------------ # Active Directory Server settings domain = example.com server_host = ldap://xxx.xxx.xxx.xxx:389 search_base = dc=example, dc=com version = 3 timeout = 30 # Active Directory Searcher settings bind = yes bind_dn = cn=Mail Administrator, cn=Users, dc=example, dc=com bind_pw = ********* # Filter Query query_filter = (&(&(objectCategory=person)(|(mail=%s)(userPrincipalName=%s)))(!(userAccountControl:1.2.840.113556.1.4.803:=2))) result_attribute = userPrincipalName result_filter = %s/ chase_referrals = no ------------------------ The packet was done with wireshark by using this definition and a capture doing and a similar test were done to dovecot. It is a setting of dovecot. ------------------------ hosts = xxx.xxx.xxx.xxx:389 dn = cn=Mail Administrator, cn=Users, dc=example, dc=com dnpass = ********* auth_bind = no ldap_version = 3 base = dc=example, dc=com user_attrs = unixHomeDirectory=home,uidNumber=uid,gidNumber=gid user_filter = (&(&(objectCategory=person)(userPrincipalName=%u))(!(userAccountControl:1.2.840.113556.1.4.803:=2))) pass_attrs = userPrincipalName=user,unixUserPassword=password pass_filter = (&(&(objectCategory=person)(userPrincipalName=%u))(!(userAccountControl:1.2.840.113556.1.4.803:=2))) iterate_attrs = userPrincipalName=user iterate_filter = (&(objectCategory=person)(!(userAccountControl:1.2.840.113556.1.4.803:=2))) default_pass_scheme = MD5 ------------------------ # Schema of LDAP is matched to Windows Services for UNIX, # and the password is made a hush with MD5. Both dovecot and postfix the first "bindRequest" was quite the same demand and the results. Next, dovecot demanded query of "userPrincipalName" and "unixUserPassword". It seems to be ok for the result. # This fails if it doesn't add to "Account Operators" group. However, "name" and "simple" were issued by the blank (anonymously?) as for the following next demand (bindRequest). In addition, query of "userPrincipalName" and "unixUserPassword" is issued to "cn=Configuration, dc=example, dc=com" afterwards. And, "Operations Error" is returned because of this. Error description in LDAP packet: ------------------------ errorMessage: 000004DC: LdapErr: DSID-0C0906DC, comment: In order to perform this operation a successful bind must be completed on the connection., data 0, v1db0 ------------------------ Because LDAP is unprofessional, it has not understood though the source code was seen. Do you serve as a reference? Thanks powerful codes.
