foreach(address, port = nil, account = nil, password = nil, isapop = false) public

Starts a POP3 session and iterates over each POPMail object, yielding it to the block. This method is equivalent to: 

    Net::POP3.start(address, port, account, password) do |pop|
      pop.each_mail do |m|
        yield m
      end
    end

This method raises a POPAuthenticationError if authentication fails.

Example

    Net::POP3.foreach('pop.example.com', 110,
                      'YourAccount', 'YourPassword') do |m|
      file.write m.pop
      m.delete if $DELETE
    end
