[bitfolk] Yahoo! breaks every mailing list in the world (including this one)

Hi, Yahoo! have made a change to their DMARC settings in a way that is incompatible with how Internet mailing lists tend to operate. As a result it is likely that members of this list (5 of you) with a Yahoo! email account will start to cause email delivery issues for others subscribers. As this is not something that we can easily fix, and represents a failure to understand how the Internet works on Yahoo!'s part, I have had to moderate those 5 members. My best suggestion is for those affected to change email address if you wish to continue posting to this and other mailing lists. Sorry about that. The technical issue is that Yahoo! now requires that all email with a Yahoo! email address as its From: address to have originated on Yahoo!'s network. Mailing lists relay mail on behalf of users, using their own envelope sender address in order to catch bounces, but keeping the original's From: address. As a result they send email that appears to be from an individual, but originates elsewhere. Yahoo!'s current DMARC settings cause sites that use DMARC to reject such emails. Unfortunately this is not just limited to Yahoo!. It includes Gmail, Hotmail, Comcast and other large email providers. So if a Yahoo! user sends an email to this list, multiple subscribers will reject it. This will go to bounce processing and ultimately may start kicking people off the list.
