     3In early April, Yahoo changed their email policies (and called this change ''aggressive level of [http://www.dmarc.org/ DMARC]'') in an effort to stop spam and pishing against it's users.

    5 As a result of the changes, email messages sent to our email lists that are from a Yahoo address will bounce when delivered to many providers, including but not limited to gmail and comcast accounts. Once enough bounces are recorded, these subscribers (the gmail and comcast subscribers) will be removed from your lists.
     5As a side effect, they are pressuring their users (and users of other email providers) to avoid using third party email distribution infrastructures.

    15 Yahoo has published information to all mail providers telling them to reject any message that claims to be from Yahoo that does not properly prove it was sent from a Yahoo server. When you send a message to an email list, the email list will resend that message to all subscribers to that list. As a result, the message is not being sent from a Yahoo server, it is being sent from the server running the mailing list. When accepting email, servers are not able to verify that the message was coming from Yahoo, so they reject the message.
