your hotmail address once again bounced a series of emails and when that happens we stop sending to your email address. This is to stop us blasting 100s of emails over and over again to dud email addresses. It costs a tiny bit to send, clogs our system and apparently contributes to an email sender being marked as a spammer. Are you doing anything odd with your email? Forwarding / filtering etc? Have you whitelisted us?
In answer to your question - "don't know" and "no". Regarding the latter it would be pointless to do this when they don't get through.
