[Dovecot-news] v2.2.33 released

https://dovecot.org/releases/2.2/dovecot-2.2.33.tar.gz
https://dovecot.org/releases/2.2/dovecot-2.2.33.tar.gz.sig

We’re getting close to the last v2.2.x releases. Hopefully we’ll have the first v2.3 beta releases out soon.

* doveadm director commands wait for the changes to be visible in the
whole ring before they return. This is especially useful in testing.
* Environments listed in import_environment setting are now set or
preserved when executing standalone commands (e.g. doveadm)

+ doveadm proxy: Support proxying logs. Previously the logs were
visible only in the backend’s logs.
+ Added %{if}, see https://wiki2.dovecot.org/Variables#Conditionals
+ Added a new notify_status plugin, which can be used to update dict
with current status of a mailbox when it changes. See
https://wiki2.dovecot.org/Plugins/NotifyStatus
+ Mailbox list index can be disabled for a namespace by appending
“:LISTINDEX=” to location setting.
+ dsync/imapc: Added dsync_hashed_headers setting to specify which
headers are used to match emails.
+ pop3-migration: Add pop3_migration_ignore_extra_uidls=yes to ignore
mails that are visible in POP3 but not IMAP. This could happen if
new mails were delivered during the migration run.
+ pop3-migration: Further improvements to help with Zimbra
+ pop3-migration: Cache POP3 UIDLs in imapc’s dovecot.index.cache
if indexes are enabled. These are used to optimize incremental syncs.
+ cassandra, dict-sql: Use prepared statements if protocol version>3.
+ auth: Added %{ldap_dn} variable for passdb/userdb ldap
– acl: The “create” (k) permission in global acl-file was sometimes
ignored, allowing users to create mailboxes when they shouldn’t have.
– sdbox: Mails were always opened when expunging, unless
mail_attachment_fs was explicitly set to empty.
– lmtp/doveadm proxy: hostip passdb field was ignored, which caused
unnecessary DNS lookups if host field wasn’t an IP
– lmtp proxy: Fix crash when receiving unexpected reply in RCPT TO
– quota_clone: Update also when quota is unlimited (broken in v2.2.31)
– mbox, zlib: Fix assert-crash when accessing compressed mbox
– doveadm director kick -f parameter didn’t work
– doveadm director flush resulted flushing all hosts, if
wasn’t an IP address.
– director: Various fixes to handling backend/director changes at
abnormal times, especially while ring was unsynced. These could have
resulted in crashes, non-optimal behavior or ignoring some of the
changes.
– director: Use less CPU in imap-login processes when moving/kicking
many users.
– lmtp: Session IDs were duplicated/confusing with multiple RCPT TOs
when lmtp_rcpt_check_quota=yes
– doveadm sync -1 fails when local mailboxes exist that do not exist
remotely. This commonly happened when lazy_expunge mailbox was
autocreated when incremental sync expunged mails.
– pop3: rawlog_dir setting didn’t work
