Hello Dovecot users,
I release a new version of Pigeonhole tonight. This release extends the
configuration capabilities of the include and vacation extensions, adds
the ihave extension (RFC 5463), and fixes a few small other things.
Judging by Timo's plans, this will be one of the last feature releases
for Dovecot v2.0, since I'll be switching active development to Dovecot
v2.1 once that matures a little more.
+ Vacation extension: finally added support for using the original
recipient in vacation address check. It is also possible to disable
the recipient address check entirely. Check doc/vacation.txt for
+ Include extension: made limits on the include depth and the total
number of included scripts configurable. Check doc/include.txt for
+ Implemented ihave extension. This allows checking for the availability
of Sieve language extensions at 'runtime'. Actually, this is checked
at compile time. At runtime the interpreter checks whether extensions
that were not previously available are still unavailable. If the
situation changed, the script is re-compiled and the ihave tests are
+ Sieve: optimized compilation of tests that yield constant results
(i.e. known at compile tme), such as 'true' and 'false'. No code is
produced anymore for script sections that are never executed. Also,
semantics are not verified anymore in uncompiled script sections.
+ Made vnd.dovecot.debug extension available to the LDA plugin instead
of only the command line tools.
+ Sieve: redirect action now adds X-Sieve-Redirected-From header
(mainly for people using SPF/SRS).
- Sieve: fixed bug in handling flags and keywords; in case of error an
assertion was triggered.
- Script storage: improved handling of unconfigured user home directory.
Originally this would produce an unhelpful error message.
- Imap4flags extension: prevent forcibly enabling imap4flags when
imapflags is enabled.
- Fixed various -Wunused-but-set-variable compiler warnings.
- Include extension: forgot to check variable identifier syntax for
- Sieve: fixed debug mode; no messages were logged in some situations.
- sievec tool: forgot to enable -D (debug) parameter.
The release is available as follows:
Refer to http://pigeonhole.dovecot.org and the Dovecot v2.0 wiki for
more information. Have fun testing this new release and don't hesitate
to notify me when there are any problems.
So it's time for the first alpha version of Dovecot v2.1. There are no
huge intrusive changes, so I expect v2.1.0 to be released this year
(maybe even in a few months?)
The biggest changes are related to full text search handling. I'll
probably still make some changes to it and its configuration. Also it
wouldn't be difficult to add more backends, does anyone want to add
Xapian support for Dovecot? :)
Mailbox list indexes are intended to improve performance of IMAP STATUS
command lookups, since they could be simply looked up from the index
without even opening the mailbox. TODO related to this: 1) optimize
virtual mailbox handling so that it doesn't need to actually open all of
the mailboxes' index files, it can simply look at the mailbox list index
for changes. 2) Implement IMAP NOTIFY extension using this.
Statistics tracking can be used to look at what's happening currently in
your system and also its history. You can look at what's happening in
command/session/user/domain/ip level. "doveadm stats top" gives a list
of currently running sessions and sorts them by whichever is using the
most disk io/cpu/whatever. "doveadm stats dump" followed by one of the
levels shows you a raw dump of everything stored in that level.
It would be nice if someone wrote a pretty Ajaxy HTML stats browser
where you could zoom in/out of levels. I'd also like to hear if anyone
has suggestions on how to improve what stats are gathered or how they
could be exported. (I've thought about SNMP, but I'm not entirely sure
how to export the data nicely using it.)
Finally here's the NEWS file:
* Plugins now use UTF-8 mailbox names rather than mUTF-7:
acl, autocreate, expire, trash, virtual
* auth_username_format default changed to %Lu. If you really want
case sensitive usernames, set it back to empty.
* Solr full text search backend changed to use mailbox GUIDs instead of
mailbox names, requiring reindexing everything. solr_old backend can
be used with old indexes to avoid reindexing, but it doesn't support
some newer features.
+ imapc (= IMAP client) storage allows using a remote IMAP server to
be used as storage. This allows using Dovecot as a smart (caching)
proxy or using dsync to do migration from remote IMAP server.
+ Mailbox indexing via queuing indexer service (required for Lucene)
+ Lucene full text search (FTS) backend rewritten with support for
+ FTS finally supports "OR" search operation
+ FTS supports indexing attachments via external programs
+ IMAP FUZZY extension, supported by Lucene and Solr FTS backends
+ Mailbox list indexes
+ Statistics tracking via stats service. Exported via doveadm stats.
+ Autocreate plugin creates/subscribes mailboxes physically only when
the mailbox is opened for the first time. Mailbox listing shows the
autocreated mailboxes even if they don't physically exist.
+ Password and user databases now support default_fields and
override_fields settings to specify template defaults/overrides.
- listescape plugin works perfectly now
