I need a solution
Dear Gentlemen,
we are using microsoft outlook , the user used to send me the spam-email as attachment and wants me to block it . So, please can you provide me with the best practice and way to get the information of the sender's domain and IP ? and what is the best way to block it and not give him any chance to reach my network again even if he did some changes or use aliases .
any comment or correction or answer will be helpful and will be highly appreciated
