SIS: dovecot creates duplicated attachments (sometimes)
by Alexander Moisseev 20 Jul '18

20 Jul '18

SIS deduplication was broken in 2.2.16 and has been fixed with https://github.com/dovecot/core/commit/3b39022ea0513363241cf852b7d454c84158… but still sometimes (just several times in a month or so) dovecot creates duplicated attachments. As you can see in directory listings below all attachments was created at (about) the same time, but one of them has different inode number. It easy to discover using https://github.com/moisseev/doveadm-tools/blob/master/bin/dsisck # dsisck -n mail_uid=vmail mail_attachment_dir=/vmail/attachments ==> Checking SIS... # ln -f ./30/b3/30b367c584a123eee59478adf3e4f4c9e1226545-c56eae04a67c3157287f01003d96bafd ./30/b3/30b367c584a123eee59478adf3e4f4c9e1226545-7ad0a411d17c31572b7a01003d96bafd #

Hello! I have a problem with a sieve-script which works for one domain but not for another one. Both domains are hostet on the same server running dovecot and postfix. This is the script that works: require ["vacation"]; # rule:[Out of office] if true { vacation :days 1 :addresses "a.meyer(a)nimmini.de" :subject "absent" "Ich bin nicht da."; } This one does not, a vacation message is not sent: require ["vacation"]; # rule:[Out of office] if true { vacation :days 1 :addresses "a.meyer(a)bitcorner.de" :subject "absent" "Ich bin nicht da."; } I don't know why.

v2.3.2 released
by Timo Sirainen 04 Jul '18

04 Jul '18

https://dovecot.org/releases/2.3/dovecot-2.3.2.tar.gz https://dovecot.org/releases/2.3/dovecot-2.3.2.tar.gz.sig v2.3.2 is mainly a bugfix release. It contains all the changes in v2.2.36, as well as a bunch of other fixes (mainly for v2.3-only bugs). Binary packages are already in https://repo.dovecot.org/ * old-stats plugin: Don't temporarily enable PR_SET_DUMPABLE while opening /proc/self/io. This may still cause security problems if the process is ptrace()d at the same time. Instead, open it while still running as root. + doveadm: Added mailbox cache decision&remove commands. See doveadm-mailbox(1) man page for details. + doveadm: Added rebuild attachments command for rebuilding $HasAttachment or $HasNoAttachment flags for matching mails. See doveadm-rebuild(1) man page for details. + cassandra: Use fallback_consistency on more types of errors + lmtp proxy: Support outgoing SSL/TLS connections + lmtp: Add lmtp_rawlog_dir and lmtp_proxy_rawlog_dir settings. + submission: Add support for rawlog_dir + submission: Add submission_client_workarounds setting. + lua auth: Add password_verify() function and additional fields in auth request. - doveadm-server: TCP connections are hanging when there is a lot of network output. This especially caused hangs in dsync-replication. - Using multiple type=shared mdbox namespaces crashed - mail_fsync setting was ignored. It was always set to "optimized". - lua auth: Fix potential crash at deinit - SSL/TLS servers may have crashed if client disconnected during handshake. - SSL/TLS servers: Don't send extraneous certificates to client when alt certs are used. - lda, lmtp: Return-Path header without '<' may have assert-crashed. - lda, lmtp: Unencoded UTF-8 in email address headers may assert-crash - lda: -f parameter didn't allow empty/null/domainless address - lmtp, submission: Message size limit was hardcoded to 40 MB. Exceeding it caused the connection to get dropped during transfer. - lmtp: Fix potential crash when delivery fails at DATA stage - lmtp: login_greeting setting was ignored - Fix to work with OpenSSL v1.0.2f - systemd unit restrictions were too strict by default - Fix potential crashes when a lot of log output was produced - SMTP client may have assert-crashed when sending mail - IMAP COMPRESS: Send "end of compression" marker when disconnecting. - cassandra: Fix consistency=quorum to work - dsync: Lock file generation failed if home directory didn't exist - Snippet generation for HTML mails didn't ignore &entities inside blockquotes, producing strange looking snippets. - imapc: Fix assert-crash if getting disconnected and after reconnection all mails in the selected mailbox are gone. - pop3c: Handle unexpected server disconnections without assert-crash - fts: Fixes to indexing mails via virtual mailboxes. - fts: If mails contained NUL characters, the text around it wasn't indexed. - Obsolete dovecot.index.cache offsets were sometimes used. Trying to fetch a field that was just added to cache file may not have always found it.

Released Pigeonhole v0.5.2 for Dovecot v2.3.2.
by Stephan Bosch 04 Jul '18

04 Jul '18

Hello Dovecot users, Here's the Pigeonhole release that goes with Dovecot v2.3.2. You will need this release for Dovecot v2.3.2, because the previous v0.5.1 release will not work. No changes were performed since the release candidate. Much like version 0.4.24 for Dovecot v2.2, this release consists mostly of fixes that accumulated over the last few months. Beyond that, this release contains the new IMAP FILTER=SIEVE capability, which was also released earlier with 2.2.24 (with a few additional fixes). Changelog v0.5.2: + Implement plugin for the a vendor-defined IMAP capability called "FILTER=SIEVE". It adds the ability to manually invoke Sieve filtering in IMAP. More information can be found in doc/plugins/imap_filter_sieve.txt. - The Sieve address test caused an assertion panic for invalid addresses with UTF-8 codepoints in the localpart. Fixed by properly detecting invalid addresses with UTF-8 codepoints in the localpart and skipping these like other invalid addresses while iterating addresses for the address test. - Make the length of the subject header for the vacation response configurable and enforce the limit in UTF-8 codepoints rather than bytes. The subject header for a vacation response was statically truncated to 256 bytes, which is too limited for multi-byte UTF-8 characters. - Sieve editheader extension: Fix assertion panic occurring when it is used to manipulate a message header with a very large header field. - Properly abort execution of the sieve_discard script upon error. Before, the LDA Sieve plugin attempted to execute the sieve_discard script when an error occurs. This can lead to the message being lost. - Fix the interaction between quota and the sieve_discard script. When quota was used together with a sieve_discard script, the message delivery did not bounce when the quota was exceeded. The release is available as follows: https://pigeonhole.dovecot.org/releases/2.3/dovecot-2.3-pigeonhole-0.5.2.ta… https://pigeonhole.dovecot.org/releases/2.3/dovecot-2.3-pigeonhole-0.5.2.ta… Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information. Have fun testing this release and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

How to log a Sieve match in Dovecot debug_log
by Lukas 01 Jul '18

01 Jul '18

Hi everybody! I manage a mail server running Dovecot 2.2.21 with Pigeonhole 0.4.10. I successfully configured sieve and use it also to filter some spam messages. Here is one of the script I use to filter messages on the basis of prohibited words in message body. As you can see, the last command writes to the log the action of this script. -- the script begins ------------ require ["fileinto", "imap4flags", "editheader", "body", "vnd.dovecot.debug"]; if anyof ( body :text :contains "crypto", body :text :contains "sex", body :text :contains "viagra" ) { setflag "\\Seen"; addheader :last "X-Sieve-Filtered" "blocked words in message body"; fileinto "INBOX.Spam"; debug_log "Body contains blocked word: <the matching word>"; } -- the script ends -------------- MY QUESTION: is there a way to have also the result of the match in that log message? I mean, is it possible to have that "<the matching word>" substituted with the exact word that matched one of the conditions (more or less the same way it is possible using Exim's System Filter)? I googled and searched a lot Dovecot documentation but wasn't able to find a definite YES or NO to this question. Thanks a lot! Lukas

Auto configure email clients from Dovecot?
by Davide Marchi 30 Jun '18

30 Jun '18

Hi Friends, I'm using on Debian Jessie, Dovecot 1:2.2.13-12~deb8u3. I would like to know if is it possible to auto-configure the email client, for example Thunderbird or K-9 mail. Essentially I would like to know if is it possible to let dovecot instruct the mail client about how to auto-configure the email client. Actually my mail server parameters are not automatically taken from Thunderbird or K9-Mail. Is there a way to make this possible? Or am I on a wrong path? Many many thanks! Davide Italy

We have an existing Dovecot/Postfix/Roundcube email solution, which I was hoping to add Caldav (and carddav?) support to, with the goal of 3rd party email clients being able to keep contacts and calendars in sync (as well as having the same information in roundcube) In doing research, I came across traces of it being considered for Dovecot at one time (https://www.dovecot.org/list/dovecot/2015-September/101996.html) and I was wondering where this went. Specifically, https://www.dovecot.org/list/dovecot/2015-September/101997.html seemed to hint that metadata support was a prerequisite for this (mainstream as of the email), and I was wondering if this meant there was potentially a solution built on top of this. Thank you -- Nathan Coulson
