[CentOS] Mailman 2.1.16 or later for CentOS 5

Is there a repository with a newer version of mailman for CentOS 5?  CentOS 5 
ships with mailman 2.1.9 and it looks like I need some of the features of 
newer version of mailman to cope with DMARC issues relating to aol, yahoo, and 
hotmail with at least one of my mailman lists.
