mailbox plugin adds support to ikiwiki for
rendering mailbox file into a page displaying the mails
in the mailbox. It supports mbox, maildir, and MH folders,
does threading, and deals with MIME.
One hitch I noticed was that it is not currently possible to treat a maildir or an MH directory as a page (i.e. just call it foo.mh and have it transformed to page foo). I'm not sure if this is possible and worthwhile to fix. It is certainly workable to use a [[!mailbox ]] directive. -- DavidBremner
