Non Delivery of message to email accounts ending with '.it'

hi there,
I have IMail 8.01 server in my win2k server. I have noticed that all mails to the email address ending with '.it ' as well as ".cy" are being returned, All other are working... I tried to send email at ".it" through my hotmail account it went fine.
Nebody know whats wrong do i have to change some settings in the IMail or what?
