so, supposedly mailman 2.1.16+ has a feature that allows you to configure mailman lists so yahoo won't have a hissy with their new implementation of DMARC. http://www.spamresource.com/2014/04/up-in-arms-about-yahoos-dmarc-policy.htm...

has anyone packaged this as an RPM for CentOS 5 ? I currently have mailman 2.1.9 from whatever repo it came from (probably base?)
