sorry for this generic mail system question
i've got a problem with hotmail; when i send mail to a particular domain (
example.com)
sometimes it bounce back saying :

This is an automatically generated Delivery Status Notification.

Delivery to the following recipients failed.

as(a)example.com

Final-Recipient: rfc822;as(a)example.com <rfc822%3Bas(a)example.com>
Action: failed
Status: 5.7.1
Diagnostic-Code: smtp;554 5.7.1 <as(a)example.com>: Recipient address
rejected: Access denied

it's not even reaching the recipient's mx

but sometimes it get delivered; the problem started very recently;

any clue about this!
appreciate some guidance
