PHPApplication for send email

Hello, Your job is to create a small PHP application that allows me to dedicate my server shipments via email with a link to a text database with 5 million email addresses. This application will allow me to download. CSV format my database (segmented into 35 separate files of between 2M and 20M) I want to send an email to the easy spread of this database. I want to send emails is quick! (No e-mail in 2000 only 24 hours) I'm able to quickly send an email to my address 5 million) I'm able to choose the address from I'm also able to select an HTML e-mail items (No need of an editor I'll copy / paste the code) WARNING: You must program a simple and functional ... No software will not be tolerated, you can not install free programs or other law as PHPList ... This programming will be on a dedicated server performance. Thank you
