block email sender

Hi Experts,

is it possible to block one email for the whole exchange organization ?
And is it possible to block one sender just for one person (receiver) ?
Please can you show me how to do this in exchange 2007 ?

The anti-spam method can be done on a hub transport server but you need to install the AntiSpam agents first. This is a quick, simple task. See the link below for a guide.

using the hub transport rule is nice, but I have to create a contact first with this email to block. is there no other way just to type the blocked address ?
