[Dovecot] Dovecot 2.0.5 crash when It cannot remove maildir
by Len7hir 02 Nov '10

02 Nov '10

This is scenario that cause segmentation fault in my Dovecot. Maybe I do something wrong, but I don't know what... We run: mailbox_delete mailbox_delete do: mailbox_open(box) < 0 and after we have: box->v.delete(box) which run index_storage_mailbox_delete index_storage_mailbox_delete do: mailbox_close(box); and now mailbox is closed (this close box->view and mailbox open) Try to delete folder, but can't do this... example becaus it is system folder, or NFS failure... set error message and return -1. Now we are returning to mailbox_delete. And we have: if (ret < 0 && box->marked_deleted) and this is true mailbox_mark_index_deleted(box, FALSE) if (box->marked_deleted && del) this is false mail_index_transaction_begin(box->view, trans_flags); mail_index_view_ref(view) and segmentation fault, because view is 0x0 #0 mail_index_view_transaction_ref (view=0x0) at mail-index-view.c:81 #1 0xb7ef3214 in mail_index_transaction_begin (view=0x0, flags=MAIL_INDEX_TRANSACTION_FLAG_EXTERNAL) at mail-index-transaction.c:268 #2 0xb7eb7a73 in mailbox_mark_index_deleted (box=0x80c8268, del=false) at mail-storage.c:682 #3 0xb7eb80a9 in mailbox_delete (box=0x80c8268) at mail-storage.c:757 #4 0x0805001f in cmd_delete (cmd=0x8095978) at cmd-delete.c:46 #5 0x0805625c in client_command_input (cmd=0x8095978) at imap-client.c:741 #6 0x0805630b in client_command_input (cmd=0x8095978) at imap-client.c:791 #7 0x0805646d in client_handle_input (client=0x8095390) at imap-client.c:857 #8 0x08056f1f in client_input (client=0x8095390) at imap-client.c:908 #9 0xb7e6f110 in io_loop_handler_run (ioloop=0x806c370) at ioloop-epoll.c:212 #10 0xb7e6da98 in io_loop_run (ioloop=0x806c370) at ioloop.c:350 #11 0xb7e5b26a in master_service_run (service=0x806c2c0, callback=0x805f800 <client_connected>) at master-service.c:496 #12 0x0805f6da in main (argc=1752462689, argv=0x73616d2d) at main.c:358 This is Dovecot error or I do something wrong? -- Len7hir

[Dovecot] Problem with namespace (maybe bug?)
by l.chelchowski 02 Nov '10

02 Nov '10

Hi! Could you tell me what is wrong with an "existence" of mailbox? Please see the two examples: . list "" "*" * LIST (\HasNoChildren) "/" "Trash" * LIST (\HasNoChildren) "/" "Junk" * LIST (\HasNoChildren) "/" "Sent" * LIST (\HasNoChildren) "/" "Drafts" * LIST (\HasNoChildren) "/" "Archives" * LIST (\HasNoChildren) "/" "INBOX" * LIST (\HasNoChildren) "/" "Public/AddressBook" * LIST (\HasNoChildren) "/" "Public/PublicMails" * LIST (\Noselect \HasChildren) "/" "Shared/dziobak" * LIST (\Noselect \HasChildren) "/" "Shared/tester2" * LIST (\HasNoChildren) "/" "Shared/dziobak/root" * LIST (\HasChildren) "/" "Shared/tester2/sdfgsg" * LIST (\HasChildren) "/" "Shared/tester2/sdfgsg/gsdfgf" * LIST (\HasChildren) "/" "Shared/tester2/sdfgsg/gsdfgf/vtyjyfgj" * LIST (\HasChildren) "/" "Shared/tester2/sdfgsg/gsdfgf/vtyjyfgj/rtdhrthxs" * LIST (\HasNoChildren) "/" "Shared/tester2/sdfgsg/gsdfgf/vtyjyfgj/rtdhrthxs/zhfhg" .

[Dovecot] Help with implementing quota warning
by Joy 02 Nov '10

02 Nov '10

Dear All, I am using the latest version of doveot-2.0.6 and using dovecot-lda to deliver mail in to Maildir. I have successfully implemented the global quota as well as per user quota using ldap for storing per user quota. Now i am trying to send warning message when user exceed quota limit of 80% and 95% but unable to implement the same.

Hi. On Dovecot 1.2.x it is possible to run multiple auth daemons. Is it possible on dovecot 2.0.x ? (Setting "process_min_avail" for auth service gives this error message: "doveconf: Fatal: Error in configuration file /etc/dovecot/dovecot.conf: service(auth): process_min_avail is higher than process_limit") Sample configuration for dovecot 1.2.8: auth default { count = 10 mechanisms = plain passdb ldap { args = /etc/dovecot/dovecot-ldap.conf } userdb ldap { args = /etc/dovecot/dovecot-ldap.conf } user = root } auth lda { mechanisms = plain passdb ldap { args = /etc/dovecot/dovecot-ldap.conf } userdb ldap { args = /etc/dovecot/dovecot-ldap.conf } user = root socket listen { master { path = /var/run/dovecot/auth-master mode = 0666 } } }

[Dovecot] Help Dovecot / vpopmail auth process...
by postmaster＠cyborspace.com 02 Nov '10

Please forgive my previous posts, sending mail manually since i cant get the auth to work. Thought i had the body cut and pasted correctly. I am pulling my hair out, i think I know what is wrong - i just cant find out how to fix it. Using Debian - lenny it appears that the auth process - is not looking for / seeing the proper file or database for the lookup. i would like it to point to the cdb file stored ~/domains/%d/ <---- assuming the %d = domains - and the file would then be vpasswd.cdb......

[Dovecot] Namespace subscription issue
by Brad Davidson 02 Nov '10

02 Nov '10

I'm a little confused about how public namespaces work with subscriptions. If I set subscriptions=no and subscribe to the folders, the subscription entries go into the user's private subscription file and that's fine. However, I am unable to pull their status with the LIST-EXTENDED extension. Normal listing works OK: A0004 LIST "" "*" RETURN (STATUS (MESSAGES UNSEEN)) * LIST (\NonExistent) "/" "Public" * LIST () "/" "Public/Public One" * STATUS "Public/Public One" (MESSAGES 0 UNSEEN 0) * LIST () "/" "Public/Public One/Sub 1" * STATUS "Public/Public One/Sub 1" (MESSAGES 0 UNSEEN 0) * LIST () "/" "Public/Public One/Sub 2" * STATUS "Public/Public One/Sub 2" (MESSAGES 0 UNSEEN 0) * LIST () "/" "Public/Public Two" * STATUS "Public/Public Two" (MESSAGES 0 UNSEEN 0) * LIST () "/" "Public/Read-only" * STATUS "Public/Read-only" (MESSAGES 1 UNSEEN 0) A0004 OK List completed. Listing SUBSCRIBED (or LSUB) fails: A0003 LIST (SUBSCRIBED) "" "*" RETURN (STATUS (MESSAGES UNSEEN)) * LIST (\Subscribed) "/" "Public/Public One" * NO Mailbox doesn't exist: Public.Public One * LIST (\Subscribed) "/" "Public/Public One/Sub 1" * NO Mailbox doesn't exist: Public.Public One.Sub 1 * LIST (\Subscribed) "/" "Public/Public One/Sub 2" * NO Mailbox doesn't exist: Public.Public One.Sub 2 * LIST (\Subscribed) "/" "Public/Public Two" * NO Mailbox doesn't exist: Public.Public Two * LIST (\Subscribed) "/" "Public/Read-only" * NO Mailbox doesn't exist: Public.Read-only A0003 OK List completed. If I set subscriptions=yes it works OK, but then the subscriptions are shared unless I override SUBSCRIPTIONS in the mail location. Is this working as designed? Here's what I ended up doing - is there a better way? namespace { inbox = yes location = prefix = separator = / type = private } namespace { hidden = yes list = no location = maildir:%h/Maildir prefix = ~/mail/ separator = / type = private } namespace { type = public separator = / prefix = Public/ location = maildir:/var/mail/public:INDEX=~/Maildir/public:SUBSCRIPTIONS=~/Maildir/ public/subscriptions subscriptions = yes } --- Brandon 'Brad' Davidson Virtualization Systems Administrator University of Oregon Information Services (541) 346-8098 brandond(a)uoregon.edu

[Dovecot] What causes the quota information to get updated?
by Patrick Westenberg 02 Nov '10

02 Nov '10

Hello, if new mails arrive, the quota information is updated and reported via imap immediately. However, after deleting a message, nothing happens. Even if I delete all messages and the mailbox e.g. was over quota, new mails won´t be accepted because the mailbox is over quota. Is this the way it should be or a misconfiguration? # 2.0.4: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 2.6.26-2-amd64 x86_64 Debian 5.0.5 auth_mechanisms = plain login log_timestamp = "%Y-%m-%d %H:%M:%S " mail_debug = yes mail_gid = vmail mail_location = mdbox:~/mdbox mail_plugins = quota mail_uid = vmail managesieve_notify_capability = mailto managesieve_sieve_capability = comparator-i;octet comparator-i;ascii-casemap fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date namespace { inbox = yes location = prefix = INBOX. separator = . type = private } passdb { args = /usr/local/etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { quota = dict:User quota::file:%h/mdbox/dovecot-quota quota_rule2 = INBOX.Trash:storage=+50M quota_warning = storage=95%% quota-warning 95 %u quota_warning2 = storage=5%% quota-warning 5 %u sieve = ~/.dovecot.sieve sieve_global_path = /usr/local/etc/dovecot/sieve/default.sieve } protocols = imap sieve service imap-login { service_count = 1 } service managesieve-login { inet_listener sieve { port = 4190 } inet_listener sieve_deprecated { port = 2000 } service_count = 1 } ssl = required ssl_cert = </etc/ssl/certs/imap_wk-serv_net.crt ssl_key = </etc/ssl/certs/imap_wk-serv_net.key userdb { args = /usr/local/etc/dovecot/dovecot-sql.conf.ext driver = sql } protocol imap { mail_plugins = $mail_plugins imap_quota }

[Dovecot] LDAP acl_groups - can multivalue LDAP be used
by ian+dovecot＠comtek.co.uk 02 Nov '10

02 Nov '10

Hi, Is there some kind of way to get acl_groups out of LDAP without having to maintain an entry with a list of groups 'a,b,c' and so on? Our groups have a list of 'member' attributes with CNs pointing at users. Ideally there would be a way to look this up directly. Alternately I could perhaps use an OpenLDAP overlay to show 'group' attributes for each user's ldap entry. I would then like to be able to tell it to get all 'group' attributes and comma-separate them. The best option I've seen so far is something like http://www.dovecot.org/list/dovecot/2010-March/047731.html which seems to involve a completely separate LDAP session from a login script. Thanks in advance for any help, Ian

[Dovecot] problem with folder creation
by John Watson 02 Nov '10

02 Nov '10

I am running dovecot 1.2.12 on Free BSD 8.1. We also have postfix and a version of squirrelmail for the UI. We are using MySql database to store the email account info. I wrote a script to insert about 100K users into mysql. Those accounts seem to work well and I'm able to see things like 'Drafts', 'Trash' and 'Sent'. Now I am working on code to create new accounts - one at a time. The accounts get created and I can send and receive email from them but when I go go Drafts, Sent or Trash I get an error that says: ERROR: Could not complete request. Query: SELECT "INBOX.Drafts" Reason Given: Mailbox doesn't exist: INBOX.Drafts When I go out and look at the mailbox folders for these users I only see "cur", "new", and "tmp" whereas on other accounts that work well I also see things like INBOX.Drafts etc. I have examined the sql that is inserting the accounts in bulk versus the one by one case and can not see any differences (other than a new mailbox name/password etc). Everything that I'm reading online indicates that Dovecot should just create these extra folders on the server and there is really nothing for either an admin or a user to do. Does anyone have any more information on this? Thanks in Advance John Watson
