It's listed on zen.spamhaus.org because it's in pbl.spamhaus.org which is a policy blocklist:

Time Warner Cable/Road Runner's policy is not to permit outbound email for this IP address range.
so, using a roadrunner mail server as a "smarthost" is the only viable choice
Or some other server where they are willing to whitelist that address. We do this for several of our customers who are on networks that have delivery problems of one kind or another, usually on a port other that 25 to get around outgoing blocks or automatic redirection to a broadband provider's server.
