<div dir="ltr">Further from that, if you have DMARC enabled, and also have DMARC exception reporting enabled, expect to be spammed with a copy of every email your domain sends to bigpond customers who have opted into <a href="http://outlook.com">outlook.com</a> accounts for their bigpond email. The bigpond/outlook integration seems a little broken, and <a href="http://outlook.com">outlook.com</a> reports a DMARC violation on every email.
