Hi. This would be kind of cool to have in bincimap.
http://www.jedi.claranet.fr/qmail-compression.patch "This is a patch against the Qmail mail server. Messages will be saved in Maildir spools as gzip files, and the POP3 server uncompresses them on-the-fly. It may save a lot of hard disk space and does not change anything to the POP3 nor SMTP protocols." -- Regards // Oden Eriksson, Deserve-IT.com
