Email from one specific company is bouncing
I'm getting a bounce notification from DistroKid.com only. All other email seems to be getting through.
DistroKid are simply notifying me (via a website banner) that the emails are bouncing. I've checked with them and their response is "If your emails can't get through, maybe your host is blocking them".
Do Apple block certain IPs or domains from sending to icloud accounts?
