You can use iterator style #pop.

  # Example: CUI base progress bar

  Net::POP.start(host, 110, user, pass) {|pop|
    pop.each_mail do |msg|
      $stderr.print 'reading a message: '
      read = 0
      msg.pop do |chunk|
        read += chunk.size
        if (read * 100 / msg.size) >= 10
          $stderr.print '.'
          read = 0
        end
      end
      $stderr.puts
      # msg.delete
    end
  }

Result:

  % ruby poptest.rb
  reading a message: .........
  %
