hardlinkpl finds duplicate files and hardlinks them, especially but not only on Cyrus mail spools. The memory footprint is bearable low, making it possible to search huge file systems of several hundred gigabytes. Inspired by hardlinkpy.
MailDB adds a database back-end to an IMAP server for features such as "virtual" mail folders (msgs appearing in multiple folders), "view" folders (dynamic results of searches), etc. The DB is inherently multi-user, allowing msg reference counting.
PerlTix flags in/outgoing mail which allows internal addresses (i.e. support@ includes: tech1@, tech2@) to be reached through a single point of entry (i.e. support@). The ticket-ID also allows the admin to cross-ref w/other sub-systems (eg. webserver)
