The American Kennel Club rejected mine because the domain was “too similar” to their name. I guess just because it had a “kc” in it? Completely bewildering.
I use this scheme (company@mydomain.com) and one that I remember blocking for this reason is Aliexpress/Alibaba - aliexpress@mydomain.com was rejected so I use ali@mydomain.com.
No idea what sort of security this is supposed to provide.
