I’m using postmarkapp.com to allow bbpress members to post to forum using an email, but in order for postmarkapp.com to work It requires an inbound webhook to be accessible publicly. Right now s2member blocks that url and treat it as restricted content, and it redirect to login page:
xxx/wp-admin/admin-post.php?action=bbsub
I need to know how to remove restriction for one specific URL please (above url), and treat it as any public page or post on the site.
Thank you
