Can you add ASAP a new function for the filter? As your filter only can add unwanted email one by one. It is good for your blocking tool that can add all unwanted emails in one click to block list. However, your blocking tool can not stop many bloody senders as they use different "false replying email address" to bypass your blocking tool and send again and again their spam emails to your customers even we add them to block list. Therefore please add a function to identify the same sender like their name too so that your customers can block them, in order to save your internet traffic and to improve your internet speed too. In fact we have found it takes much longer time to receive an email by testing to use yahoo mail system.
