Microsoft is the only mail provider that exhibits this behiavor.  And I've 
heard the same thing from other people using small domains.

The Microsoft autobot response a few years ago said "the domain didn't 
send enough emails."  I don't know why I would send more emails to a 
provider which doesn't deliver them.

Maybe Microsoft has reasons, but no customer service answer.

Gmail, Yahoo, and others don't have a problem.

Maybe Microsoft allows your small domain as an exception?  In the mean 
time, use Gmail or another cloud provider to get your email.
