Version 2.4.0 of maildrop
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: This release adds support for setting IMAP keywords with Courier-IMAP 2.1 and higher.
