Seeking recommendation: VPS/Dedi provider with extremely clean/good IP reputation
Title says it all. We're on a dedicated server and, despite reprovisioning IPs a few times, we end up with several on RBLs before we've even used them -- sometimes for IP-specific behavior, sometimes because we're in a larger block deemed to be bad.
Our own mail is clean; we could just route it all through SES or some other external SMTP, but we'd prefer not to. I'm shopping but can't find any rankings based on average IP reputation. Does such a thing exist? Any recommendations? Thanks!
