its not like that. Hotmail sends
"Hello!" message to the sending server for the email address which was responsible to send email to hotmail address and server needs to respond to that
"Hello!" with
"Ok!"
If the server fails to send
"Ok!" message then the sent email is dumped. cPanel servers have this feature by default and
OK! message is sent by default for nobody and root emails.
