Dovecot lifecycle announcement
by Aki Tuomi 03 Aug '18

03 Aug '18

Hi! We are giving the following end of life (EOL) statements: For any version before 2.2, we are not going to be providing any patches or fixes. This has been the case before, but we are now officially declaring them EOL. For 2.2 versions, we are going to provide security and critical bug fixes for 2.2.36 only. If you are using 2.2.x version prior to .36, we will not be providing anything other than critical security fixes. This means that if you are experiencing a problem with Dovecot, we need you to upgrade into latest 2.3 release and reproduce the problem there. If this happens, please file a bug report and we are more than happy to take a look! If you are using a 2.2.x version packaged from an Operating System Vendor, please open a bug against them for fixing it. We do not provide patches or bug fixes against these OS Vendor specific releases. 2.3.x is the current main release, which will receive feature, bug and security patches. We accept bug reports against latest 2.3 version or master version of Dovecot. If you need packages for 2.3, please see https://repo.dovecot.org. Thank you for using Dovecot! Note: Users with a commercial agreement with Open-Xchange (Dovecot Pro) have a separate EOL policy, so this announcement does not apply to those customers. Aki Tuomi Open-Xchange Oy

Released Pigeonhole v0.5.2 for Dovecot v2.3.2.
by Stephan Bosch 29 Jun '18

29 Jun '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

v2.3.2 released
by Timo Sirainen 29 Jun '18

29 Jun '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.

Hello Dovecot users, Here is the Pigeonhole release that goes with the new Dovecot v2.2.36 release. Apart from the changes that were already in the RC, this final release adds one new feature: a plugin for the IMAP FILTER=SIEVE capability. The is a vendor-defined feature that adds the ability to manually invoke Sieve filtering in IMAP. Changelog v0.4.24: + 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. - Fix assert panics triggered by empty messages that are being forwarded using redirect or vnd.dovecot.report. This does not likely normally occur, but this is seen as a result of certain benign failures in object storage. - 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.

We didn't fix everything reported (especially build changes) to try to minimize any unexpected breakages. v2.3.2 will be out with a lot of fixes hopefully in a few weeks.

Also don't do CRL checks for incoming client certificates. * stats plugin: Don't temporarily enable PR_SET_DUMPABLE while opening /proc/self/io.
