Local Packages
Updated dovecot to 2.2.19:
pop3_deleted_flag has been broken since v2.2.10, and using it would cause buffer overflows, which could be exploitable; however, this bug would have become visible quite soon after users had deleted some POP3 mails, because the pop3 processes would have started crashing all the time even in normal use
"doveadm director flush" command has a changed meaning now: it safely moves users to their wanted backends, instead of simply forgetting the mapping entirely and leaving the existing connections untouched; use the -F parameter to get the original unsafe behaviour
Added imap-hibernate processes (see imap_hibernate_timeout setting); IDLEing IMAP connections can be hibernated, which saves memory
Optimized tracking mailboxes' vsizes (= sum of all messages' sizes); if mailbox_list_index=yes, it's also stored in there, which makes it very efficient to look up vsizes for all mailboxes
Added a quota "count" backend, which uses the mailbox vsizes to get the current quota usage; it requires using the new quota_vsizes=yes setting, which tracks the messages' "virtual sizes" rather than "physical sizes" (their distinction is minor and mostly irrelevant nowadays - if mail sizes should be counted with LF or CRLF newlines)
"doveadm director up/down" commands added; the monitoring script should be using these commands instead of changing the vhost count, which allows admin to manually disable a server by changing the vhost count to 0 without the monitoring script changing it back
Added support for HAProxy protocol: http://wiki2.dovecot.org/HAProxy
Added push-notification plugin framework, which can be used to easily implement push notifications to various backends; implemented "ox" backend for notifying Open-Xchange via HTTP/json
imap_logout_format supports more variables now, e.g. number of deleted messages
pop3: Added pop3_delete_type setting (related to pop3_deleted_flag)
plugin { fts_enforced=yes } setting now fails body searches unless it can be done via the full text search engine
Added %{passdb:*} and %{userdb:*} variables to various places
auth: Added ":protected" suffix for passdb and userdb fields; if used, the field doesn't overwrite an existing field
IMAP/POP3 proxy: If a backend server dies, avoid client reconnection spikes by slowly disconnecting clients over time; this is enabled by setting login_proxy_max_disconnect_delay=secs passdb extra field
imap: Added new read-only METADATA entries: /private/specialuse, /shared/comment, /shared/admin
imap: If client disconnects in the middle of a command, log how long the command had been running
mdbox: Rebuilding could have caused message's reference count to overflow the 16-bit number in some situations, causing problems when trying to expunge the duplicates
Various search fixes (fts, solr, tika, lib-charset, indexer)
- Various virtual plugin fixes
Various fixes and optimizations to dsync, imapc and pop3-migration
imap: Various RFC compliance and crash fixes to NOTIFY
Also updated pigeonhole to 0.4.9:
Properly implemented checking of ABI version for Sieve interpreter plugins, much like Dovecot itself does for plugins; this will prevent plugin ABI mismatches
Implemented a vnd.dovecot.environment extension; this builds upon the standard environment extension and adds a few more environment items, such as username and default mailbox, and also creates a variables namespace so that environment items can be accessed directly
Sieve extprograms plugin: Made line endings of the input passed to the external programs configurable; this can be configured separately for each of the three extensions
ManageSieve: Implemented proxy XCLIENT support; this allows the proxy to pass client information to the back-end
ManageSieve: Fixed an assert failure occurring when a client disconnects during the GETSCRIPT command
doveadm sieve plugin: Fixed incorrect initialization of mail user; this caused a few memory leaks
sieve-filter command line tool: Fixed handling of failure-related implicit keep when there is an explicit default destination folder; this caused message duplication
lib-sieve: Fixed bug in RFC5322 header folding, in which words longer than the optimal line length caused empty lines in the output, which would break the resulting message header; this surfaced in References: headers with very long message IDs
Updated perl-DateTime-Format-Strptime to 1.57:
Make all tests pass with both the current DateTime::Locale and the upcoming new version (currently still in trial releases)
Updated python-zope-interface to 4.1.3:
Fix installation without a C compiler on Python 3.5 (https://github.com/zopefoundation/zope.interface/issues/24)
