[Dovecot] Managesieve error
by Tim Traver 15 Jun '10

15 Jun '10

Hi all, ok, I am updating to the 2.0 way of doing things and have managed to get everything set up right, except I am getting the following errors when attempting to use managesieve with our webmail client (roundcube) that I didnt get when using dovecot 1.2.11... Jun 14 17:20:33 managesieve(address(a)domain.com): Warning: sieve-storage: Active sieve script symlink /home/mailboxes/data/domain/348/address(a)domain.com/.dovecot.sieve is broken: invalid/unknown path to storage (points to Maildir/sieve/roundcube.sieve). I checked, and the link appears to be there, and is a proper symlink to the sieve file... Here is the copy of my dovecot -n : # 2.0.beta6: /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 8.0-RELEASE-p3 i386 auth_username_format = %Lu auth_username_translation = %@ auth_verbose = yes disable_plaintext_auth = no dotlock_use_excl = yes first_valid_uid = 100 listen = * lock_method = dotlock log_path = /local/logs/dovecot.errors mail_gid = 100 mail_location = maildir:%h/Maildir mail_nfs_index = yes mail_nfs_storage = yes mail_uid = 100 mmap_disable = yes passdb { args = /bin/checkpassword_dovecot_auth driver = checkpassword } plugin { quota = maildir sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = imap pop3 managesieve quota_full_tempfail = yes ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = prefetch } userdb { args = /bin/checkpassword_dovecot_deliver driver = checkpassword } verbose_proctitle = yes protocol lda { mail_plugins = quota sieve } protocol imap { mail_plugins = quota imap_quota } protocol pop3 { pop3_client_workarounds = outlook-no-nuls oe-ns-eoh }

[Dovecot] Dovecot v2.0.beta6 - child ppppp killed with signal 11
by Mark Sapiro 15 Jun '10

15 Jun '10

Since upgrading from 2.0beta5 to beta6, I have seen a few pairs of log messages like the following: Jun 13 15:57:17 sbh16 dovecot: imap-login: Maximum number of connections from user+IP exceeded (mail_max_userip_connections=30): user=<gpc>, method=PLAIN, rip=76.126.100.210, lip=72.52.113.35, mpid=0, TLS Jun 13 15:57:17 sbh16 dovecot: master: Error: service(imap-login): child 16960 killed with signal 11 (core not dumped - add -D parameter to service executable The "Maximum number of connections from user+IP exceeded" message is not new - this is an issue with the K9 mail client on an android phone - but the killing of the child is new in beta 6. Is this intentional. -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B. Dylan

2.0.beta6 assert-fails for me when: - using mdbox (maildir is OK) - my authentication module returns the mail= and mail_location= attributes (relying on mail_location from 10-mail.conf is OK) - a user logs in for the first time and selects his nonexistent INBOX The error is: Panic: file mailbox-list.c: line 318 (mailbox_list_get_unexpanded_path): assertion failed: (*location == '0') The location string is "1mdbox:/Volumes/Mail/joe".

[Dovecot] convert Plugin Error
by Bradlee Landis 14 Jun '10

14 Jun '10

I am getting an error when using the convert plugin for dovecot. Jun 14 13:27:20 mail dovecot: IMAP(user): Mailbox conversion: rename(/home/user/mail, /home/user/mail-converted) failed: Directory not empty Dovecot creates mail-converted, but does not delete mail completely for some reason. It continues to add a message from the mbox to Maildir format, creating duplicates every time I check my email. I can fix it by deleting mail-converted, but I don't want this to happen to other users on the system. Does anyone have a clue as to why it's doing this, and what I can do to fix it? I can send you my mbox file and home directory structure if you'd like to take a gander at it. Dovecot v1.0.7 Scientific Linux 5.4 (Importing mbox files from RHEL 3.8). -- Thanks, Brad Landis

[Dovecot] Ubuntu upgrade to 10.04 --> dovecot no longer working
by HenkR 14 Jun '10

14 Jun '10

Hi, Last year I installed dovecot on my Ubuntu V9 system 64 bit system. I use it to store emails from several clients in the LAN using IMAP. Last week I upgraded to Ubuntu 10.04. Now Dovecot is no longer working. It started with messages about sieve, so I disabled sieve in the configuration file (did not use it in the past, don't know what it is). Dovecot can now be started without errors or warnings, but I cannot connect in the client. I get a message saying "could not connect to server: connection refused". Can anybody help? kind regards, Henk -- View this message in context: http://old.nabble.com/Ubuntu-upgrade-to-10.04---%3E-dovecot-no-longer-worki… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] v2.0.beta6 released
by Timo Sirainen 14 Jun '10

14 Jun '10

http://dovecot.org/releases/2.0/beta/dovecot-2.0.beta6.tar.gz http://dovecot.org/releases/2.0/beta/dovecot-2.0.beta6.tar.gz.sig Unfortunately this still isn't rc1 yet, but the next one will be, I promise :) Basically all of the important changes are done now. The TODO list for rc1 is: - Test and fix dsync bugs - Finish director - Add man pages started by Pascal Volk. BTW. He asked for some feedback about them, but got only one reply: http://dovecot.org/list/dovecot/2010-June/049438.html I've also read through and answered nearly all of my email backlog. If you haven't gotten a reply, resend the mail. Some changes since beta5: - Added director: http://blog.dovecot.org/2010/05/new-director-service-in-v20-for-nfs.html - IMAP: Added STATUS (X-VSIZE) command for easily getting mailbox's virtual size. - Lots and lots of doveadm improvements and new commands - Postlogin scripts now need to be executed using "script-login", not "script" binary. - Quota warnings are executed now asynchronously using the new script binary. See http://hg.dovecot.org/dovecot-2.0/rev/a179fcbbf960 - Added passdb static for proxying and similar configurations - TLS SNI configuration must now be done using local_name {} blocks, not local {} - lib-storage plugin API changes, external plugins must be updated to work correctly - Lots of fixes

[Dovecot] Shared Mailbox Questions
by Chris Hobbs 11 Jun '10

11 Jun '10

Hi All, I've pored over the wiki, read through the archive, and have what I believe should be a working set-up, but I can't seem to get my shared namespace to work correctly. Any guidance would be much appreciated. I started off using a flat file for acl_shared_dict and ran into the same problem recently reported with the shared-database file getting chown'd to the first user to touch it with 0600 permissions. So I thought I'd give it a whirl with sqlite. Here are the (hopefully) relevant bits from dovecot -n (the entire output is posted below). This is dovecot 1.2.9 running on a freshly installed ubuntu 10.4 server: namespace: type: shared separator: / prefix: shared/%%u/ location: maildir:/home/staff/%%n/Maildir:INDEX=~/Maildir/shared/%%u list: children plugin: acl_shared_dict: proxy::acl dict: acl: sqlite:/etc/dovecot/acl-shared-dict.conf acl-shared-dict.conf looks like this: connect = /home/staff/dovecot/acl-shared-ns.sqlite map { table = acl_shared_ns pattern = shared/shared-boxes/user/$to/$from value_field = has_visible_folders fields { from_user = $from to_user = $to } } /home/staff/dovecot/acl-shared-ns.sqlite is set 0666, and I can add records to it from the sqlite command line as a normal user. The table was created with: CREATE TABLE acl_shared_ns (from_user, to_user, has_visible_folders, PRIMARY KEY (from_user) ON CONFLICT REPLACE); When I attempt to SETACL from a telnet imap session, I get the following errors in mail.err: Jun 9 22:10:23 imap2 dovecot: dict: dict sql iterate failed: file is encrypted or is not a database Jun 9 22:10:23 imap2 dovecot: dict: dict sql iterate failed: file is encrypted or is not a database Jun 9 22:10:23 imap2 dovecot: dict: sqlite: exec(INSERT INTO acl_shared_ns (has_visible_folders,to_user,from_user) VALUES ('1','chobbs','IOchoa')) failed: file is encrypted or is not a database (26) Jun 9 22:10:23 imap2 dovecot: IMAP(IOchoa): read(/var/run/dovecot/dict-server) failed: Remote disconnected Jun 9 22:10:23 imap2 dovecot: IMAP(IOchoa): acl: dict commit failed Jun 9 22:10:23 imap2 dovecot: dovecot: child 8268 (dict) killed with signal 11 (core dumps disabled) Running that same "INSERT INTO..." as the IOchoa user from the sqlite command line works just fine. At this point any further deleteacl or setacl commands simply hang, presumably because there's no longer a running dict process. Here is the entire output of dovecot -n: # 1.2.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-22-server x86_64 Ubuntu 10.04 LTS log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s managesieve listen(default): * listen(imap): * listen(pop3): * listen(managesieve): *:2000 disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login login_executable(managesieve): /usr/lib/dovecot/managesieve-login mail_privileged_group: mail mail_uid: mail mail_gid: mail mail_location: maildir:~/Maildir mmap_disable: yes mail_nfs_storage: yes mail_nfs_index: yes mbox_write_locks: fcntl dotlock mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_executable(managesieve): /usr/lib/dovecot/managesieve mail_plugins(default): acl imap_acl mail_plugins(imap): acl imap_acl mail_plugins(pop3): mail_plugins(managesieve): mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 mail_plugin_dir(managesieve): /usr/lib/dovecot/modules/managesieve namespace: type: private separator: / inbox: yes list: yes subscriptions: yes namespace: type: shared separator: / prefix: shared/%%u/ location: maildir:/home/staff/%%n/Maildir:INDEX=~/Maildir/shared/%%u list: children lda: deliver_log_format: %$ -- FROM=%f SUBJECT=%s mail_plugins: cmusieve acl log_path: info_log_path: syslog_facility: mail postmaster_address: postmaster(a)nhusd.k12.ca.us hostname: mail.nhusd.k12.ca.us auth default: passdb: driver: pam passdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf userdb: driver: passwd userdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf plugin: acl: vfile acl_shared_dict: proxy::acl sieve: ~/.dovecot.sieve sieve_dir: ~/sieve dict: acl: sqlite:/etc/dovecot/acl-shared-dict.conf Chris Hobbs Director, Technology New Haven Unified School District -- This message was scanned by ESVA and is believed to be clean.
