Public Instance methods

all( dest = '' )

Alias for pop

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

mail( dest = '' )

Alias for pop

pop( dest = '' ) {|message_chunk| ...}

This method fetches the message. If called with a block, the message is yielded to the block one chunk at a time. If called without a block, the message is returned as a String. The optional dest argument will be prepended to the returned String; this argument is essentially obsolete.

Example without block

    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

Example with block

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