Just started getting some delivery failures when sending to mailhooks. Is there a chance of a sending domain being blocked so that the mailhook is not accepting it?
No SMTP servers were available for mailhook-latenode.com. Tried route3.mx.cloudflare.net, route2.mx.cloudflare.net, route1.mx.cloudflare.net.
This behavior is seen through one service but not through a different one.
