Release Notes: Search patterns are now MIME-aware. Search patterns are now specified in the UTF-8 codeset, and will get transcoded to the mail's character set, as indicated by the MIME headers.
Release Notes: This release changes the effective group ID of processes started by maildrop, on some configurations, to maildrop's effective group ID rather than maildrop's parent process' effective group ID. This eliminates a potential privilege escalation if maildrop was invoked by a process with a more privileged effective group ID than maildrop.
Release Notes: This release adds minor performance improvements to the reformail tool. An external program invoked to filter a message that terminated before consuming its standard input is no longer considered an error. Maildrop's license was changed to the GPLv3.
Release Notes: Messages delivered by maildrop will use the process's inherited umask. The -f option now allows an empty return address to be specified. The lockmail utility now drops any group-id privileges if the setgid bit was added to lockmail's permissions.
Release Notes: The agent now uses the PCRE library for regular expression pattern matching, with optional reversion to the old built-in legacy pattern matching engine.
Release Notes: This release adds support for setting IMAP keywords with Courier-IMAP 2.1 and higher.
Release Notes: This release adds updated maildir delivery code that uses a revised mechanism for creating message filenames that is less likely to produce duplicate filenames.
Release Notes: A bug in "reformime -h" was fixed and deliverquota's functionality was merged into maildrop.
Release Notes: This release includes a new configuration script from the updated autoconf/automake toolchain. The dotlock utility has been superseded by lockmail, with improved support for legacy mbox lock files.
Release Notes: This release features enhanced support for maildir quotas. Reliability of maildir quota support was improved, and there's now a documented process to change an existing maildir quota.
