Hi All,

Unfortunately, yahoo has chosen to break just about all mailing lists on the planet. 

We are trying to come up with a solution. Unfortunately, those we have come up with are not good. 

More on the problem can be found below. 


"On April 8 Yahoo implemented a new DMARC policy that essentially bars any Yahoo user from accessing mailing lists hosted anywhere except on Yahoo and Google. While Yahoo is the initiator, it also affects Comcast, ATT, Rogers, SBGlobal and several other ISPs. Internet Engineering Council expert John R. Levine, specialing in email infrastructure and spam filtering claimed in a post .Yahoo breaks every mailing list in the world including the IETF's.. on the Internet Engineering Task Force (IETF) list.
