chewmail is a program for archiving mail. It is inspired by the by the
Python-based archivemail, but with more useful semantics. All mail
is archived to the mailbox specified with the --output-box switch,
in mbox format. It can read mailboxes in mbox, Maildir and MH formats.
Internally, chewmail uses Mail::Box,
so it supports file namesand URLs supported by that module.
