Alert HN: Exim being exploited in the wild

Just got bit by an Exim exploit on Slicehost. I'm not sure, but I think Exim is installed by default in Centos 5. Here is a link to the exploit, or at least a similar one http://www.exim.org/lurker/message/20101207.215955.bb32d4f2.en.html. Please check all of your servers for Exim, and remove it ASAP.
