From the Mailing List admins at JiscMail: --- Yahoo have recently changed the security settings on their email servers which is causing major issues with mailing list services across the world, including JiscMail.
Yahoo have changed their security settings in a way that causes emails sent through a mailing list service to be identified as junk-mail by email providers that using certain security systems. This causes many email providers including Google, Microsoft and Yahoo themselves, to reject any list emails originating from a Yahoo account. These rejections, can in some cases, cause subscribers to be removed from lists due to the number of rejected messages. In order to protect our subscribers and our service we have been advised to stop Yahoo subscribers from posting to *any* JiscMail lists and we have implemented this change. Yahoo subscribers will still receive messages from lists. --- If you have subscribed through a Yahoo mail account you will still get mails, but can no longer post to the list. If you wish to post please unsubscribed the Yahoo account resubscribe using a different email provider. Best wishes, Tim
