Hello good afternoon, I have problems with the domain server, they do not allow me to send emails to the following domains (hotmail.com, outlook.com).
I received this message
----- The following addresses had fatal errors -----
[Status: Error, Address: <
operacionesgreen@hotmail.com>, ResponseCode 421, RP-001 (BAY004-MC4F25) Unfortunately, some messages from 135.84.80.217 weren't sent. Please try again. We have limits for how many messages can be sent per hour and per day. You can also refer to

Check the problem in troubleshoot and then inform me the reason for the failure: it is temporarily deferred
