Swift mailer

I need a mass mailer script using swift class. It is for a newsletter. The mail type and description : - HTML email - containing 2 (not embeded) images (1 logo, 1 image - the message/brochure kind) - at bottom will be a not spam text message and an unsubscribe link - both images will be links to the website and will have a click counter for statistics (I have the statistics script so will just have to have a link to my counter) - the mail will also have a counter for "email opened" (a php image - I supply the link) Very important: - emails will not be blocked by yahoo - header configurations - assistance needed for DKIM or other (just to be sure email will be received by most users)
