Found it Catty
Can't get to it from the Email page though

Puzzling?

The route to the Block Email setting is this way unless somebody has a better idea

Copy that address first,just the
digitalmail.com part.
Now go out of the email altogether to the MSN Homepage
Look to the Left and find the My Settings click on that then #9 on the List
Next locate this on the Next page
Block SendersBlock the delivery of messages from specific addresses or from entire domains.
click on this link
On the next Screen, paste that address into the left hand box and then click the "Add" button to put it in the right frame then press the "OK" button to save and Exit
Thats it ...Is that what you wanted?
PS There is also a "safe" list section which gives any address you designate access past the filter or Block (like a firewall)
