Mass mailer PHP Modification

I have a massmailer php script custom coded here in rac . I need some modification. The script is made to load email address with txt files. The disadvantage is whenever i want to send mail to the list . every time I have to upload the txt files to the server. I have about 100 text files containing 400 million email addresses. So i can't upload every time to send a single email to every one in the list Here is the solution 1]Once the txt file is uploaded i have to choose the text files which i want to email in the interface. 2] Otherwise use mysql database and i will provide all the email address txt files you convert it into a mysql database and make necessary changes in the database. Also create an interface for importing the txt files for future use. And one more thing i want to add these features also 1] how many people opened the mail out of total sent 2] total number of total sent emails 3] campaign manager i will give you full access to my server you have too install it and test it. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
