What's the best way to screen vps / dedi by IP reputation?
I love my current provider, but either they or their upstream datacenter cannot seem to provide clean IPs. If I spin up a mail server, inevitably I find out that not just that particular IP but the whole class C block is blocked for prior bad behavior.
I could farm out our mail, but I don't want to, so that leaves me wondering how to sort future VPS or dedicated-server providers by IP reputation. Any ideas?
