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
