bulk smtp server required

Need an offshore SMTP server to send out emails with Sendblaster 2 - Ideally must have reverse DNS & DKNY keys enabled for best delivery. Should be able to switch to another IPs if it gets blacklisted for some reason or better yet be setup to work in rotation with a pool of 5-10 IP adresses. Should be able to send 100,000-200,000 email/Day. Will pay per month for a total of $600 USD/Year : to be clear MONTH per MONTH payment, not all $600 in advance. Thanks
