We've used Postmark for a while, it's worked great. Considered moving to Mandrill for a while, to reduce the cost (they had a free tier) but never ended up doing it. Now I'm happy we never did, since they just axed/reshaped their service :) (on dedicated IPs, it's worth mentioning that reputation is moving from IP to domain, with DKIM et. al., so it's not as important as it used to be)
