Unable to send email

if i send email(a Hotmail or outlook account) i received a notification= "This is an automatically generated Delivery Status Notification.

Unable to deliver message to the following recipients, because the message was forwarded more than the maximum allowed times. This could indicate a mail loop."

1.)my message is new.

2.)i did not forward it.

3.) i tried to a different recipients and it still comes up that notification.

Anyone can help me.??? maybe i did wrong in my email.settings or what so ever.
