This is the blog post I wanted to write :) I’m just behind on getting to p=quarantine. There are 2 things slowing me down: 1. As I just replied to Franck - enforcing inbound (which is my primary goal) - I need to handle mailing lists (and I don’t want to wait for ARC adoption). So I have to figure out all the mailing lists my users are posting to so I can whitelist those IPs coming back unless anyone wants to share a list? :) 2. Google seems to report itself as a DMARC failing sender for unrelated domains to me. This really started in earnest in March, but I’m getting 40k-60k what seem like unrelated reports a day, for example: Domain MAIL FROM DKIM domain SPF Auth DKIM Auth Total akamai.com oppa.com.br oppa-com-br.20150623.gappssmtp.com Pass Pass 237 So that’s killing my confidence on publishing p=quarantine (I can fake one inbound). Are others seeing this, or am I a special snowflake? Thanks John
