I am in need of an emailing system that will allow me to send 150,000 emails a day, with growth of about 4000-6000 more emails per month (meaning next month it would be 155,000 per day, and so on.) I want a robust system built to get around spam filters and automated blocking. Anyone with any experience doing this. Specifically with the idea of a solution on a dedicated server. The use of multiple ips and domains. And of course all the required features such as SPF, DKIM and anything else that might be needed. I have a basic understanding, and will be capable of using and maintaining the system after its built, but I have never set up a system like this from scratch. Thoughts? Anyone around here have these talents and want to get paid to build up a system for me?
