Hi,

I modified my code, I'm afraid that I can't find it. It is like the
following:

class MailInfo
  def initialize
    @path=@recipients=@from=Array.new
    ...
  end
  def parse
         case header
	when "TO", "CC", "BCC"
		@recipients << header
	when "RECEIVED"
		@path << header
         end
  end
  ...
end

in the above code, the arrays will interfere with each other. The way to
solve it is not to use chained assignment.

Thanks
Shannon
