class responsible for sending html newsletter (images attached!)

I need a php class that will be responsible for sending html newsletter. All images must be attached in an e-mail (not referenced from web) so that it is always displayed in e-mail clients. This is a template: [login to view URL] the class must accept path to header image (header image will change from newsletter to newsletter) and also array of articles. Each article has - title - path to image (path on local server, saved somewhere using administration) - text - URL of link Everything else can be hardcoded. For sending, I prefer zend framework class (Zend_Mail) Other upon negotiation, class should not rely on any other framework set of libraries!
