And, even if it *is* unreasonable, well, his network, his rules, right? "I block all SMTP traffic from IPV4 servers (clients?) which have odd numbers in the third octet." might not be a good idea for a high volume mail server with clients, but if it's your network, go for it. -- _________________________________________ Nachman Yaakov Ziskind, FSPA, LLM awacs () ziskind us Attorney and Counselor-at-Law http://ziskind.us Economic Group Pension Services http://egps.com Actuaries and Employee Benefit Consultants
