Emails being sent by WordPress.orgWordPress.org The community site where WordPress code is created and shared by the users. This is where you can download the source code for WordPress core, plugins and themes as well as the central location for community conversations and organization. https://wordpress.org/ & WordCampWordCamp WordCamps are casual, locally-organized conferences covering everything related to WordPress. They're one of the places where the WordPress community comes together to teach one another what they’ve learned throughout the year and share the joy. Learn more. WordPress instances are currently SPF softfail’ing, I suspect that’s what has caused Gmail to mark all contact requests from a WordCamp site to me (and the rest of the team) as spam.
This is happening as the bounce reply address is currently set to bouce@wp.com which doesn’t accept w.org IP ranges as SPF permitted senders (as expected).
WordPress.org emails are DKIM signed (where as WordCamp ones are not), so i suspect that’s why they don’t get marked as spam.
Relevant part of a WordCamp email:
Received-SPF: softfail (google.com: domain of transitioning bounce@wp.com does not designate 66.155.40.24 as permitted sender) client-ip=66.155.40.24;
