PHPMailer Advanced Loop PHP-MySQL

I am using my over modified version of PHPMailer open source code. for more info visit: [login to view URL] 1. Here is the page I created: [login to view URL] a. the page uses 1 MySQL database that stores the email accounts and the email addresses. b. page send out emails using a gmail username / password c. will provide MySQL access -------------------------------------------------------------- WHAT I NEED: 1. An advanced looping feature that will change the sender information(gmail from address) after 10 emails and will continue to cycle through all the sending email accounts until the list is completed. Example: 100 Email Address 5 Gmail Accounts each gmail account should send out 20 of the emails. after the first 50 emails have been send it will cycle back to the first account and start over.
