I am trying to stop a person who is spamming me sending me emails. I am already added him/her to my blocked senders list but this person's emails are still getting through. How is this possible? I get about 25 spam emails a day so have set my email filters to 'exclusive' which means that unless people are in my contacts list thenm emails dont get through. Rather than having to keep adding spam email addresses to my 'blocked senders list' I have set the 'rules for new emails' which means that any spam trying to get to me with the words drugs, ****, F*buddy, prescription, life insurance etc ect doesnt get to my inbox and gets deleted immediately. I have 60 rules but still need to add more. For some reason the page isnt allowing me to do so. I can see the 'add new rule' button but there is no box for me to add what it is. So does this mean that there is maybe a 60 rule limit? How can I stop this junk mail from getting in? Everyone tells me to go to googlemail but I've had my Hotmail account for 15 years and dont like the Googlemail set up. Why is it that Hotmail users get so much junk mail? Answers to any of the above would be most appreciated. Thank you so much
