delete

Marks a message for deletion on the server. Deletion does not actually occur until the end of the session; deletion may be cancelled for all marked messages by calling POP3#reset().

This method raises a POPError if an error occurs.

Example

    POP3.start('pop.example.com', 110,
               'YourAccount, 'YourPassword') do |pop|
      n = 1
      pop.mails.each do |popmail|
        File.open("inbox/#{n}", 'w') do |f|
          f.write popmail.pop
        end
        popmail.delete         ####
        n += 1
      end
    end
