This results in emails from you guys to frequently show up in my spam folder.
Specifically, here's a subset of the headers that appeared in my most recent mod update alert email:
Code:
Received-SPF: softfail (google.com: domain of transitioning [email protected] does not designate 2600:3c00::f03c:91ff:fef1:90b6 as permitted sender) client-ip=2600:3c00::f03c:91ff:fef1:90b6;

spf=softfail (google.com: domain of transitioning [email protected] does not designate 2600:3c00::f03c:91ff:fef1:90b6 as permitted sender) [email protected]
