[Dovecot-news] v2.2.33 released



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
  • 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
  • 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
