Instance Method Details

#delete ⇒ Object 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

def inspect
  "#<#{self.class} #{@number}#{@deleted ? ' deleted' : ''}>"
end

#pop(dest = '', &block) ⇒ Object 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.
