Nothing at all. Wheres your script? (without duplicating mine although you free to use chop slate and sling it for all i care)
Ive gone down the road of web based email news letter sending and I came up with a differnet solution (not so differnt i suppose as others who have bulk mailing facilities too). But I tend to use php for web development and not so much for creating wrappers to patch various technolgies together. Who knows perhaps you only know php.
However from a web/ISP based install you would be lucky to be able to send thousands of emails via a bulk mailing app (thats my experience of shared hosting). If you have a dedicated host then perhaps your khama may be differenet and you can use it as you please.
You can be as sarcastic as you like means nowt to me. Gives me a heads up on what and who you are though and at least gives me the fine impression that this place is NOT full of geeks with their heads up their %^&&**
