Your DNS is being corrupted. twitter.com is not blacklisted, and 4.36.66.178 is not a valid result. As long as your mail filter is not using these corrupted nameservers, then it's not an issue.
Please see:

The easiest answer is to run your own nameserver on your mail filter. Most operating systems can support this.

There are sites which return with IP addresses to dns lookups, but which report as "not blacklisted" when I submit them to the lookup web page.
For example,
% dig +short twitter.com.multi.surbl.org 4.36.66.178 % dig +short test.surbl.org.multi.surbl.org 127.0.0.126
But when I enter twitter.com into http://george.surbl.org/lookup.html, it says "twitter.com is not blacklisted" in a green box. Same for test.surbl.org.
What am I missing?
