[Dovecot] Dovecot 2.0 auth socket error
by Tim Traver 18 Jun '10

18 Jun '10

Hi Timo, ok, when dovecot starts up, it creates the socket files in /usr/local/var/run/dovecot for the auth and a variety of other socket stuff you have going on. It creates these socket files with root ownership. But I have in the config files that dovecot is running as a particular user (in this case uid100 and gid100) to match the global mail systems needs. I use qmail as the delivery agent, and when qmail envokes deliver, I get the following errors in the qmail log files : @400000004c1b18f22ea7a05c delivery 1497: deferral: lda:_Error:_userdb_lookup:_connect(/usr/local/var/run/dovecot/auth-userdb)_failed:_Permission_denied_(euid=100(sn)_egid=100(sn)_missing_+w_perm:_/usr/local/var/run/dovecot/auth-userdb,_euid_is_not_dir_owner)/lda:_Fatal:_Internal_error_occurred._Refer_to_server_log_for_more_information./ Now, from what I can tell, this is complaining that the socket doesn't have write permission for the group, because it is owned by root and created with only 600 permissions...I can chmod the file to add the rw for the group, and then it appears to start working ok, but if I stop and start dovecot, it will only re-create those files with the 600 permissions... It appears that this is not happening in the version 1.2.11 code base as I this machine is a new one that I am testing 2.0 code on... Am I missing a proper setting somewhere? here is my dovecot -l : # 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 = ~/Maildir/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 pop3 { pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } protocol lda { mail_plugins = quota sieve } protocol imap { mail_plugins = quota imap_quota } Thanks, Tim.

[Dovecot] strange regex sieve filter error
by Tim Traver 18 Jun '10

18 Jun '10

Hi all, ok, I'm getting an error produced by the following sieve file : require ["fileinto","copy"]; # rule:[SPAM-TAG] if allof ( header :regex "Subject" "^\\[SPAM-TAG\\]") { fileinto "SPAM-TAG"; stop; } and I'm getting the following error in the dovecot delivery log : main_script: line 3: error: unknown tagged argument ':regex' for the header test (reported only once at first occurence). main_script: error: validation failed. But I looked up the syntax, and tried to figure out why this is getting the error. I guess I just don't quite know what this error means... I know that the value that it is trying to match is kind of strange, but it is a regular expression, so it should work... Thanks, Tim.

[Dovecot] Problem configuring rawlog with 2.0beta6
by Mark Sapiro 18 Jun '10

18 Jun '10

The initial problem I was seeing after upgrade from 2.0beta5 to 2.0beta6 was error messages from my Android phone K9 client that dovecot was reporting -1 messages in various mailboxes. These mailboxes do have the special "Mail System Internal Data" message in them. In trying to get more information for debugging, I tried toenable rawlog using the same configuration I used successfully with 2.0beta5, namely: service imap { executable = imap imap-postlogin } service imap-postlogin { executable = script rawlog unix_listener imap-postlogin { } } (full dovecot -n below), but instead of successful rawlog writes, I got the following log messages: Jun 16 19:46:36 sbh16 dovecot: script: Fatal: Client not compatible with this binary (connecting to wrong socket?) Jun 16 19:46:36 sbh16 dovecot: imap: Error: fd_read(/usr/local/var/run/dovecot/imap-postlogin) failed: disconnected So the first question is how do I configure rawlog for 2.0beta6? And the next question is why the "-1 messages". Here's dovecot -n # dovecot -n # 2.0.beta6: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 2.6.18-8.1.14.el5 i686 CentOS release 5 (Final) auth_mechanisms = plain apop login auth_worker_max_count = 5 mail_location = mbox:~/Mail:INBOX=/var/spool/mail/%u mail_privileged_group = mail mbox_write_locks = fcntl dotlock passdb { args = /usr/local/etc/dovecot.passwd driver = passwd-file } passdb { driver = pam } protocols = imap pop3 service auth { unix_listener /var/spool/postfix/private/auth { mode = 0666 } } service imap-postlogin { executable = script rawlog } service imap { executable = imap imap-postlogin } ssl_cert = </etc/postfix/sbh16-cert.pem ssl_key = </etc/postfix/sbh16-key.pem userdb { driver = passwd } protocol imap { mail_max_userip_connections = 30 } -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.

Could anybody direct me to feature comparision document or explain here main differences betweeen thos two branches? -- Veiko

[Dovecot] LDA to address extensions
by Martijn de Munnik 18 Jun '10

18 Jun '10

Hi List, I'm trying to make dovecot deliver messages to sam+extension(a)example.com to the imap folder 'extension' of the user 'sam'. I've configured postfix with these dovecot as LDA: mailbox_command = /opt/redknot/libexec/dovecot/deliver -f "$SENDER" -d "$USER" -m "$EXTENSION" -a "$RECIPIENT" recipient_delimiter = + Sam is a local system user so I don't want to use virtual_transport (I think). I've read http://wiki.dovecot.org/LDA/Postfix but so far without success. # 1.2.11: /etc/opt/redknot/dovecot.conf Warning: There is no way to login to this server: disable_plaintext_auth=yes, ssl=no, no non-plaintext auth mechanisms. # OS: SunOS 5.11 sun4v log_path: /var/log/dovecot.log ssl: no login_dir: /opt/redknot/var/run/dovecot/login login_executable: /opt/redknot/libexec/dovecot/imap-login login_max_processes_count: 10 max_mail_processes: 10 mail_location: maildir:~/Maildir lda: postmaster_address: postmaster(a)redknot.nl mail_plugins: sieve mail_plugin_dir: /opt/redknot/lib/dovecot/lda sendmail_path: /usr/sbin/sendmail auth_socket_path: /opt/redknot/var/run/dovecot/auth-master auth default: passdb: driver: pam args: other userdb: driver: passwd socket: type: listen master: path: /opt/redknot/var/run/dovecot/auth-master mode: 384 plugin: sieve_before: /etc/opt/redknot/sieve/before sieve_after: /etc/opt/redknot/sieve/after I know about the warning, this dovecot is only used as LDA, not for imap or pop3. thanks, Martijn YoungGuns Kasteleinenkampweg 7b 5222 AX 's-Hertogenbosch T. 073 623 56 40 F. 073 623 56 39 www.youngguns.nl KvK 18076568 YoungGuns Kasteleinenkampweg 7b 5222 AX 's-Hertogenbosch T. 073 623 56 40 F. 073 623 56 39 www.youngguns.nl KvK 18076568

[Dovecot] \Noselect on virtual folders
by Matthias Rieber 17 Jun '10

17 Jun '10

Hi, I've some virtual folders which seem a bit odd when they are listed. a LIST "virtual.spam." "*" * LIST (\Noselect \HasNoChildren) "." "virtual.spam." * LIST (\HasNoChildren) "." "virtual.spam.unchecked" * LIST (\Noselect \HasChildren) "." "virtual.spam.disagree" * LIST (\HasNoChildren) "." "virtual.spam.disagree.dspam" * LIST (\HasNoChildren) "." "virtual.spam.disagree.spamassassin" a OK List completed. This seems ok, virtual.spam and virtual.spam.disagree can't contain mails. I'm wondering if virtual.spam should have the flag \HasChildren instead if \HasNoChildren, but this doesn't cause trouble... a LIST (SUBSCRIBED) "virtual.spam." "*" * LIST (\Subscribed \Noselect) "." "virtual.spam.disagree.spamassassin" * LIST (\Subscribed \Noselect) "." "virtual.spam.disagree.dspam" * LIST (\Subscribed \Noselect) "." "virtual.spam.unchecked" a OK List completed. When I list the folder with (SUBSCRIBED), the virtual folders are all flagged with \Noselect. This appears at all virtual folders. All other folders don't have the \Noselect flag. On the Nokia N900 I can't enter all virtual folders. The log shows that the n900 always list the folders with (SUBSCRIBED). Is this listing the expected behaviour? regards, Matthias

[Dovecot] Shared mailboxes errors
by Nikita Koshikov 17 Jun '10

17 Jun '10

Hello list, I'm implementing shared mailboxes on live system and after enabling acl plugin I got errors in my log: Jun 17 15:50:33 dict: Error: sql dict iterate: Invalid/unmapped path: shared/shared-boxes/anyone/ I have no clue why this happening, users don't know about new functionality they just use imap as before. Also dict database begin to fill up by records like: select * from user_shares; user@domain.com|admin@domain.com|1 But user don't use setacl command. Searching for the list gave http://www.dovecot.org/list/dovecot/2009-April/038664.html , but question seemed still open. So, can someone give point how to fix\avoid this ? One more question, on live system it's hard to debug dovecot with mail_debug=yes for all users, can this option be turn on for individual user? or maybe mail_debug stream can be redirected also for individual user ?

[Dovecot] basic conf error? v1.2.11
by Justin Krejci 17 Jun '10

17 Jun '10

I just downloaded 1.2.11 and compiled from source including mysql support and using default directory locations. I walked thru the included example conf file and tweaked it out and get an invalid configuration file. I trimmed out all of the commented sections to make the non-default config super easy to navigate during troubleshooting. Remaining config which gives an error of "unknown setting: mechanisms" so I switched it to auth_mechanisms and then get the following when starting dovecot: Error: Error in configuration file /usr/local/etc/dovecot.conf line 18: Unknown section type (section changed in /usr/local/etc/dovecot.conf at line 14) Fatal: Invalid configuration in /usr/local/etc/dovecot.conf ##################### protocols = imap pop3 listen = <SCRUBBED IP> disable_plaintext_auth = no ssl = no login_processes_count = 100 login_max_processes_count = 500 login_max_connections = 512 login_greeting = DovecotProxy08 ready. protocol imap { } protocol pop3 { } protocol lda { } #LINE 14 auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@/$!&\ auth default { mechanisms = plain passdb sql { #LINE 18 args = /usr/local/etc/dovecot-sql.conf } userdb sql { args = /usr/local/etc/dovecot-sql.conf } user = root } dict { } plugin { } ##################### Any ideas what is wrong here? It seems like the example conf file is not correct. Yes the dovecot-sql.conf file exists.
