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 <host> resulted flushing all hosts, if <host> 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
