Netscape just uses mbox format for its mail files.  This *should* be
parseable by TMail::UNIXMbox, but when I try it, I get IOErrors every
time I try to do IO within TMail::UNIXMbox#each:

irb(main):021:0> var = 'hi'
=> "hi"
irb(main):022:0> mbox = TMail::UNIXMbox.new('mbox')
=> #<TMail::UNIXMbox:0x4034fc84 @closed=false, @readonly=false, @finalizer=#<Proc:0x4034fc20>, @filename="mbox", @real=#<TMail::MhMailbox /tmp/ruby_tmail_4574_0.6634130709>>
irb(main):023:0> puts "var: [#{var}]"
var: [hi]
=> nil
irb(main):024:0> mbox.each{|port| puts "var: [#{var}]" }
IOError: not opened for writing
        from /usr/lib/ruby/1.6/tmail/mailbox.rb:280:in `truncate'
        from /usr/lib/ruby/1.6/tmail/mailbox.rb:280:in `update'
        from /usr/lib/ruby/1.6/tmail/mailbox.rb:260:in `lock'
        from /usr/lib/ruby/1.6/tmail/mailbox.rb:260:in `update'
        from /usr/lib/ruby/1.6/tmail/mailbox.rb:216:in `each_port'
        from (irb):24

Looks like a bug to me.
