While the issue with Yahoo appears to be resoved, we’re still getting mail bounced by Google, so you may not receive notifications or digest emails. It seems to be intermittent so some may come through but not all.
Rackspace, our mail gateway provider, have investigated and it seems the solution is to implement authentication so Google recognises that email from the forum is legitimate. Hopefully I will get that sorted over the weekend.
