We picked up a new client and thankfully, they use Gravity Forms on their existing site. Unfortunately, it looks like form submissions are no longer being received via email (admin or user). We tried sending to the following email address extensions to no avail: @[our domain], @gmail, @yahoo, @fastmail. I wonder how we might clear up this email notification issue?
Note: It looks like their plugin and WordPress are a little out of date: v220.127.116.11 and v3.4.1, respectively.
