[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] Help with a generated sieve rule

Hi all, Can some kind soul please help me find why this rule did not work, what's wrong? I am using dovecot 1:1.2.10-0xk1. ## Generated by RoundCube Webmail SieveRules Plugin ## require ["vacation","variables"]; set "subject" ""; if header :matches "subject" "*" { set "subject" "${1}"; } # rule:[Treinamento] if anyof (true) { vacation :days 1 :subject "Ausência: ${subject}" text: Olá!

[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 17 Jun '10

17 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.

[Dovecot] ZFS Index corruption and Connection reset by peer
by Philippe Chevalier 17 Jun '10

17 Jun '10

Hello, I'm currently using dovecot 1.2.11 on FreeBSD 8.0 with ZFS filesystems. So far, so good, it works quite nicely, but I have a couple glitches. Each user has his own zfs partition, mounted on /home/<user> (easier to set per user quotas) and mail is stored in their home. From day one, when people check their mail via imap, a lot of indexes corruption occured : dovecot: IMAP(<user>@domain.org): Corrupted transaction log file /home/<user>/Mail/Maildir/INBOX/dovecot.index.log seq 13: record size too small +(type=0x0, offset=5560, size=0) (sync_offset=5652) dovecot: IMAP(<user>@domain.org): fscking index file /home/<user>/Mail/Maildir/INBOX/dovecot.index dovecot: IMAP(<user>@domain.org): /home/<user>/Mail/Maildir/INBOX/dovecot.index log position went backwards (13,132 < 13,5560) dovecot: IMAP(<user>@domain.org): Transaction log file /home/<user>/Mail/Maildir/INBOX/dovecot.index.log: marked corrupted etc, etc... After some digging, I "solved" this problem with mmap_disable = yes in dovecot.conf. Index corruption doesn't seem to occur anymore. Is this normal? I thought this problem occured only on NFS filesystem and eventually on old versions of ZFS. Hasn't this been fixed? Is there an option in ZFS that would allow mmap calls without corruption. Has it something to do with compression ? The options of the zfs filesystem are : zhome/username type filesystem - zhome/username creation Thu Mar 18 11:10 2010 - zhome/username used 750M - zhome/username available 61.0G - zhome/username referenced 750M - zhome/username compressratio 1.20x - zhome/username mounted yes - zhome/username quota none default zhome/username reservation none default zhome/username recordsize 128K default zhome/username mountpoint /usr/home/username inherited from zhome zhome/username sharenfs off default zhome/username checksum on default zhome/username compression lzjb inherited from zhome zhome/username atime off inherited from zhome zhome/username devices on default zhome/username exec on default zhome/username setuid on default zhome/username readonly off default zhome/username jailed off default zhome/username snapdir hidden default zhome/username aclmode groupmask default zhome/username aclinherit restricted default zhome/username canmount on default zhome/username shareiscsi off default zhome/username xattr off temporary zhome/username copies 1 default zhome/username version 3 - zhome/username utf8only off - zhome/username normalization none - zhome/username casesensitivity sensitive - zhome/username vscan off default zhome/username nbmand off default zhome/username sharesmb off default zhome/username refquota none default zhome/username refreservation none default zhome/username primarycache all default zhome/username secondarycache all default zhome/username usedbysnapshots 0 - zhome/username usedbydataset 750M - zhome/username usedbychildren 0 - zhome/username usedbyrefreservation 0 - Other problem, that I have been unable to solve so far, is that a lot of entries show up in my logs about : dovecot: imap-login: net_disconnect() failed: Connection reset by peer It doesn't seem to have any adverse effect, except it's filling up the logs. It seem to appear when a client closes the imap connection? Is there a way to suppress this error? Regard P.C.
