Hello Dovecot users,
Unfortunately, Pigeonhole v0.4.4 had a rather big issue with error
handling and the execution of the implicit keep. This problem presented
itself for example when users exceeded their quota. This did not result
in the proper rejection message. This is why I quickly release a new
version.
Changelog v0.4.5:
+ Added a Pigeonhole version banner to doveconf output. This way, future
bug reports will also include Pigeonhole version information.
- Fixed handling of implicit keep. Last version erroneously reported
that implicit keep succeeded after an earlier failure, while it in
fact had failed. Particularly occurred for mailbox quota errors.
- Fixed segfault occurring on SunOS systems when there is no active
script.
The release is available as follows:
http://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.5.tar…http://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.5.tar…
Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for
more information. Have fun testing this new release and don't hesitate
to notify me when there are any problems.

Hello Dovecot users,
It's been about 5 months since the last Pigeonhole release, so it is
high time for a new one. However, the main reason to make a release now
is the fact that Dovecot v2.2.15 has one change that causes problems
with the previous release of Pigeonhole.
Unlike recent earlier releases, this release has a few big new features.
Most notably, I implemented a generic Sieve script storage framework.
This means that it is now relatively easy to implement a storage driver
to retrieve Sieve scripts from a location other than the file system. An
important effect of this new implementation is that these alternative
storage locations can also be used with sieve_before/sieve_after. Also,
storing Sieve scripts there using ManageSieve is also possible, provided
that the driver provides an implementation. I used the new framework to
implement an LDAP storage driver. However, it is read-only, which means
that it doesn't currently provide ManageSieve support.
Several bugs were fixed. The most nasty ones were related to the
doveadm-sieve plugin (which is one of the reasons why this release took
so long). The new script storage driver framework entailed large changes
in this plugin, so many of these problems were addressed implicitly.
Hopefully, all problems are solved now.
Changelog v0.4.4:
* Added support for Japanese mail addresses with dots at non-standard
places in localpart.
* Changed handling of ENOSPACE into a normal temporary failure and added
handling of ENOQUOTA as a user error.
* Restructured result execution, so that all actions which involve mail
storage are always committed before all others.
+ Implemented support for generic Sieve storages. Using alternative
storages now also possible for sieve_before/sieve_after.
+ Implemented storage driver for retrieving Sieve scripts from LDAP.
This currently cannot be used with ManageSieve.
+ Implemented sieve_redirect_envelope_from setting, which allows
configuring the envelope sender of redirected messages.
- Fixed handling of mail storage errors occurring while evaluating the
input message.
- managesieve-login:
- Removed bogus ALERT response code returned for AUTHENTICATE
command.
- Fixed handling of invalid initial response argument to AUTHENTICATE
command.
- Fixed handling of stream errors in lexical scanner.
- Fixed handling of SMTP errors. Permanent and temporary errors were
mixed up.
- Fixed several problems reported by CLang 3.4.
- duplicate extension: Fixed erroneous compile error about conflicting
tags when `:handle' argument was used last.
- relational extension: Fixed error handling of `:value' match.
- editheader extension: Fixed header unfolding and header iteration.
- mailbox extension: Fixed the `:create' tag, which erroneously
subscribed an existing folder.
- extprograms plugin: Fixed handling of error codes.
- doveadm-sieve plugin: Fixed several bugs. Synchronization of symbolic
link in the file storage should now also work properly.

Some small fixes and changes to v2.2.14. This release is mainly in the hope that it could still make it into the next Debian stable instead of v2.2.14 - mainly because of a couple of new assert crashes that started happening in v2.2.14 and should be fixed now.
* Plugins can now print a banner comment in doveconf output
(typically the plugin version)
* Replication plugin now triggers low (instead of high) priority for
mail copying operations.
* IMAP/POP3/ManageSieve proxy: If destination server can't be
connected to, retry connecting once per second up to the value of
proxy_timeout. This allows quick restarts/upgrades on the backend
server without returning login failures.
* Internal passdb lookups (e.g. done by lmtp/doveadm proxy) wasn't
returning failure in some situations where it should have (e.g.
allow_nets mismatch)
* LMTP uses mail_log_prefix now for logging mail deliveries instead of
a hardcoded prefix. The non-delivery log prefix is still hardcoded
though.
+ passdb allow_nets=local matches lookups that don't contain an IP
address (internally done by Dovecot services)
+ Various debug logging and error logging improvements
- Various race condition fixes to LAYOUT=index
- v2.2.14 virtual plugin crashed in some situations

Looks like it took a bit longer to make this release after RC1 than I thought. I'm now in San Jose area for a few months and still jumping between apartments and trying to adjust to the new timezone.
Some of the more important fixes since RC1:
- Fixed several race conditions with dovecot.index.cache handling that
may have caused unnecessary "cache is corrupted" errors.
- auth: If auth client listed userdb and disconnected before finishing,
the auth worker process got stuck (and eventually all workers could
get used up and requests would start failing).
Some of the larger changes since v2.2.13:
* lmtp: Delivered-To: header no longer contains <> around the email
address. Other MDAs don't have it either.
* "Out of disk space" errors are now treated as temporary errors
(not the same as "Out of disk quota").
* replication plugin: Use replication only for users who have a
non-empty mail_replica setting.
+ lmtp proxy: Log a line about each mail delivery.
+ Added login_source_ips setting. This can be used to set the source IP
address round-robin from a pool of IPs (in case you run out of TCP
ports).
+ Rawlog settings can use tcp:<host>:<port> as the path.
+ virtual plugin: Don't keep more than virtual_max_open_mailboxes
(default 64) number of backend mailboxes open.
+ SSL/TLS compression can be disabled with ssl_options=no_compression
+ acl: Global ACL file now supports "quotes" around patterns.
+ Added last-login plugin to set user's last-login timestamp on login.
+ LDAP auth: Allow passdb credentials lookup also with auth_bind=yes
- IMAP: MODSEQ was sent in FETCH reply even if CONDSTORE/QRESYNC wasn't
enabled. This broke at least old Outlooks.
- passdb static treated missing password field the same as an empty
password field.
- mdbox: Fixed potential infinite looping when scanning a broken
mdbox file.
- imap-login, pop3-login: Fixed potential crashes when client
disconnected unexpectedly.
- imap proxy: The connection was hanging in some usage patterns. This
mainly affected older Outlooks.
- lmtp proxy: The proxy sometimes delivered empty mails in error
situations or potentially delivered truncated mails.
- fts-lucene: If whitespace_chars was set, we may have ended up
indexing some garbage words, growing the index size unnecessarily.
- -c and -i parameters for dovecot/doveadm commands were ignored if
the config socket was readable.
- quota: Quota recalculation didn't include INBOX in some setups.
- Mail headers were sometimes added to dovecot.index.cache in wrong
order. The main problem this caused was with dsync+imapc incremental
syncing when the second sync thought the local mailbox had changed.
- doveadm backup didn't notice if emails were missing from the middle
of the destination mailbox. Now it deletes and resyncs the mailbox.

I've wanted to do this release for months now, but I keep being too busy all the time. This release fixes several important bugs and a lot of smaller ones. Because there are such a large number of changes I thought I'd make this release candidate release first and the final v2.2.14 early next week.
I usually read through the Dovecot mailing list mails before making a new release to see if there are some (important) bugs reported, but I've been way too busy recently to read through everything. I still have over 250 unread mails and I don't think I'll have time to read them anytime soon.
On the positive side the Dovecot company is now hiring more people. Especially having more Dovecot coders would reduce my work load and maybe allow me to go back to reading the Dovecot mailing list daily.. See:
