If the Yahoo's violation of published email standards only affected Yahoo users we could have left off the filter but unfortunately other email providers are honoring Yahoo's DMARC setting. We do not want email from Yahoo users unsubscribing non-Yahoo addresses. 22 of the 194 addresses unsubscribed for delivery errors on 3/31 and 4/1 were not Yahoo accounts. There are currently 31 Yahoo of 428 subscribers to Calantir which means we already lost ~141 Yahoo people and maybe some of the 22 others.

Due to Yahoo's DMARC policy: listserv.unl.edu lists do not accept incoming email from Yahoo.com
