Dedicated email marketing Server

I am looking for a dedicated windows 2003 server. It will host a website that emails an opt-in list of over 100,000 recruiters and 400,000 candidates. The site will receive as many as 5-10 complaints a day due to the emailing activity. Please verify that you allow 100,000 + emails a day and you can tolerate 5-10 complaints a day. Also verify that you host other bulk emailers and have experience in handling this. The server itself needs to be 2.8 Ghz or higher, 1 GB ram, windows 2003 server. If you can tolerate the emailing activity and complaint level. I can pay $150 USD per month.
