Instance Method Details



  

    #delete  
    Also known as: #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

    #header(dest = '')  
  



  

    

Fetches the message header.



The optional dest argument is obsolete.

# File 'lib/net/pop.rb', line 759



def inspect

end


  








  

    #pop(dest = '', &block)  
    Also known as: #all, #mail
  



  

    

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



This method raises a POPError if an error occurs.

    #top(lines, dest = '')
