Traditional UNIX format is the mailbox format that has been on UNIX
systems since the 1970s. It is distinguished by flat files with messages
in LF newline form, delimited by lines that start with "From " (note the
space), an address of some sort, and a date/time of some sort.
mbx (not to be confused with "mbox") format was introduced in 1996, and is
distinquished by a flat file starting with a line consisting entirely of
the string "*mbx*". This flat file has a 2K mailbox metadata header area,
followed by messages consisting of a message metadata line containing the
size and the message text in CRLF newline form.
They are not at all alike.

mix is an indexed directory format designed for high performance with
large mailboxes. It was introduced in 2006. This is the format that UW
uses in its servers.
